[0001] The present invention relates to a machine for making a hybrid turf pitch, in particular to a filament stitching machine for a stitched hybrid turf pitch.
[0002] Turf has a plurality of functions such as pleasing to the eye, leisure, sport and the like, and is thus deeply liked by the public. In numerous functions of the turf, the sport
function has the closest relationship with people. With the constant development of economy
and culture, China pays more and more attention to the effects of sports on national culture
and physical health. A turf sports field is the basis and platform of competitive turf sports, and
the quality thereof directly determines the level of sports, the safety of sports, and the holding
level of major competitions. Sports turf is mainly divided into two categories: natural turf and
stitched hybrid turf. The natural turf has a good sport performance, is safe and pleasing to the
eye, and is good for health; therefore, the natural turf is often used as a competition field for
most competitive turf sports and competitions. However, the natural turf has the
disadvantages of low traffic resistance strength, slow regeneration speed, and being easy to
wither, degrade, catch a disease and die under the influence of environment, rainfall and
accumulated water, poor maintenance and management and the like, thus causing large areas
of baldness, and affecting competition and appearance. The stitched hybrid turf has the
characteristics of good playing performance, no water accumulation in general, high use
frequency, no environmental restriction and the like; therefore, the stitched hybrid turf can be
used as a competition field for sports (such as hockey, American football and the like) having
a high traffic intensity, great damage to the turf or special requirements. However, viscose
and a filling material used in the construction process of the stitched hybrid turf have the
problems of environmental risk, human injury risk, low safety and the like; therefore, the
stitched hybrid turf is forbidden to be used as a final sport competition field in most
competitive turf sports. Therefore, how to combine the advantages of the natural turf and the stitched hybrid turf, fully utilize the advantages and bypass the disadvantages, so as to form a new type of sports turf is an important way to effectively improve the turf technology. In the invention patent No. 201810835430.3, the inventor discloses a method for stitching artificial grass filaments to a natural turf and stitched hybrid turf. The artificial grass filaments are vertically stitched in the natural turf according to a certain gap and density, such that the advantages of the natural turf and the stitched hybrid turf can be effectively combined to form a new hybrid turf. However, during the construction of the hybrid turf, the manpower construction of the stitched hybrid turf requires a lot of time and labor, and the quality of the finished product cannot be guaranteed. Therefore, a stable, quick, and high quality stitched hybrid turf stitching machine is crucial to the successful construction of the stitched hybrid turf.
[00031 At present, the advantages of artificial filament stitching have been accepted both here and abroad. A few foreign companies apply and are granted with several foreign
patents, such as US 2003172858A1, W093/08332 and EP3 029 199 BI, wherein Sgrass Co.,
Ltd. is granted with a patent No. CN 106661850 B in China, entitled by Device for Stitching
Artificial Grass Bundle into Ground. The Chinese patent No. CN 166612754 A, entitled by
Filament Stitching Machine, also provides a filament stitching machine structure. However,
as can be seen from the filament stitching principles and structures in the patents, artificial
fiber filaments are mechanically delivered; that is, the fiber filaments are mechanically
stitched row by row; the apparatus moves forward by one row each time after the last row of
fiber filaments are stitched; therefore, the filament stitching efficiency is low; for the area of a
standard football pitch, an existing machine would take a long time to complete filament
stitching, which is far from satisfying the requirement for an artificial filament stitching field,
thus hindering the use and generalization of an artificial filament stitching machine. Artificial
filament stitching has a good effect. However, people can hardly enjoy the advantages thereof.
A sports field manager, a competent department of the state, sport enthusiasts, and the general
public all urgently appeal for a filament stitching machine with a higher stitching efficiency.
[0004] The object of the present invention is to provide a turf filament stitching machine capable of greatly improving filament stitching speed and efficiency.
[0005] The object of the present is realized by the following technical solution:
[0006] A turffilament stitching machine,
[00071 Comprising a feeding region and a filament stitching operation region, wherein
[0008] The filament stitching machine is configured to stitch a rectangular turf consisting of n rows and m columns in eachfilament stitching period; the rectangular turf
corresponds to the filament stitching operation region of the filament stitching machine;
[0009] Starting from pullout ends of m bundles of fiber filament spindles in the feeding region, m pieces of transversely-arranged filament feeding pipes are configured to
connect to a straight feeding pipe having a penetrative interior in a horizontal direction via a
flexible angle-changeable circular arc section; the straight feeding pipe horizontally
reciprocates back and forth one time in each filament stitching period, that is, an output end
of the straight feeding pipe moves from a start side of the rectangular turf to the other side;
after an end of a fiberfilament in the pipe is fixedly clamped by a clamping component on an
opposite machine frame, the straight feeding pipe returns to an original position;
[0010] The fiber filament in the pipe is delivered in two modes: an air flow delivery mode in an initial filament stitching period, and a mechanical delivery mode in a normal
filament stitching period;
[0011] In the air flow delivery mode, the fiber filament is delivered by blowing the fiber filament with compressed air;
[0012] In the mechanical delivery mode, the fiber filament is delivered with an end
head which is cut off in a previous period clamped by a clamping mechanism at an outlet end
of the straight feeding pipe and moving forward together with the pipe; after the fiber
filament is clamped by the clamping component fixed on the machine frame, the clamping
mechanism releases the end head, and the straight feeding pipe moves back;
[0013] A rectangular stereoscopic seat is fixed on the machine frame; the rectangular
stereoscopic seat has a horizontal shape the same as the rectangular turf of a filament
stitching operation, is provided with vertical through holes for n rows and m columns of
vertical filament pressing pipes corresponding to the positions of m columns of straight feeding pipes, and is provided with horizontal through holes for m columns of horizontal straight feeding pipes; a row of cutoff mechanisms are configured between the vertical through holes of two rows of transverse filament pressing pipes;
[0014] Each row of filament pressing pipes are fixed on an upright rectangular filament pressing pipe tandem arrangement frame; transverse upper and lower side frames are
respectively configured above and under the rectangular stereoscopic seat, such that the
filament pressing pipe tandem arrangement frame can drive m columns offilament pressing
pipes to move up and down on the rectangular stereoscopic seat; furthermore, the filament
pressing pipes are provided thereon with horizontal filament pressing pipe holes; at an initial
position, the filament pressing pipe holes are in communication with the horizontal through
holes of the straight feeding pipes on the rectangular stereoscopic seat; the straight feeding
pipe can pass through the two holes;
[0015] Each rectangular filament pressing pipe tandem arrangement frame is pushed
by respective filament pressing pipe pushing mechanism, and moves up and down along the
machine frame; starting from the clamping component adjacent to the machine frame, the
filament pressing pipe tandem arrangement frames move downward one by one;
[0016] After the filament pressing pipe moves downward to bend the fiber filament in
a U-shape, the cutoff mechanism cuts off the fiber filament;
[00171 Each filament pressing pipe is coaxially configured with a filament stitching
needle capable of moving up and down; a bottom end of the filament stitching needle is
higher than a bottom end of the filament pressing pipe; n rows offilament stitching needles
are divided into two or more sections; each section of m columns of filament stitching
needles are pushed by a filament stitching needle pushing mechanism to synchronously move
up and down along the machine frame, and are pressed downward under the cooperation of a
vibration apparatus;
[0018] The filament stitching needle vibrates and moves downward; the lower end
penetrates through a lower pipe orifice of the filament pressing pipe 7, and presses the fiber
filament 6 to enter the ground G by a determined depth; and
[0019] The fiber filament is an artificial plastic synthetic fiber.
[0020] In the technical solution, starting from pullout ends of m bundles of fiber filament spindles in the feeding region, m pieces of transversely-arranged filament feeding pipes are configured to connect to a straight feeding pipe having a penetrative interior in a horizontal direction via a flexible angle-changeable circular arc section; the straight feeding pipe horizontally reciprocates back and forth one time in each filament stitching period, that is, an output end of the straight feeding pipe moves from a start side of the rectangular turf to the other side; after an end of a fiber filament in the pipe isfixedly clamped by a clamping component on an opposite machine frame, the straight feeding pipe returns to an original position;
[0021] First, in the filament stitching operation region, the fiber filament on the fiber filament spindle is delivered from one side to the other side; each fiber filament is connected
to the straight feeding pipe having a penetrative interior in a horizontal direction via the
filament feeding pipe and the flexible angle-changeable circular arc section; the straight
feeding pipe must strictly reciprocate at specified positions on the machine frame in the
filament stitching region, and the m bundles of fiber filament spindles are stacked in the
feeding region; therefore, the positions are inconsistent, and the two need to be connected via
"the flexible angle-changeable circular arc section" when the filament stitching machine is
introduced to stitch filaments, such that the two can be both considered.
[0022] The fiber filament in the pipe is delivered in two modes: an air flow delivery
mode in an initial filament stitching period, and a mechanical delivery mode in a normal
filament stitching period; in the present invention, the fiber filament in the pipe is delivered in
two modes:
[0023] In the air flow delivery mode, the fiber filament is delivered by blowing the fiber filament with compressed air; the blowing is conventional compressed air blowing.
[0024] In the mechanical delivery mode, the fiber filament is delivered with an end
head which is cut off in a previous period clamped by a clamping mechanism at an outlet end
of the straight feeding pipe and moving forward together with the pipe; after the fiber
filament is clamped by the clamping component fixed on the machine frame, the clamping
mechanism releases the end head, and the straight feeding pipe moves back; the actions are
necessary for realizing the present invention; and mechanical clamping is common in industry,
and could be easily realized with multiple methods.
[00251 A rectangular stereoscopic seat is fixed on the machine frame; the rectangular stereoscopic seat has a horizontal shape the same as the rectangular turf of a filament
stitching operation, is provided with vertical through holes for n rows and m columns of
vertical filament pressing pipes corresponding to the positions of m columns of straight
feeding pipes, and is provided with horizontal through holes for m columns of horizontal
straight feeding pipes; a row of cutoff mechanisms are configured between the vertical
through holes of two rows of transverse filament pressing pipes;
[0026] Normally, the cutoff mechanism comprises n+1 rows including the two sides. However, the end head is clamped by the clamping component on the opposite machine
frame; one row will be formed as long as the end head is loosened. Therefore, totally n rows
are provided.
[00271 The "rectangular stereoscopic seat" in the present invention is distinctive, and is an important component which connects a transverse horizontal filament feeding process
step to the process step of vertically pre-bending the fiber filament and stitching the filament
in the ground. Therefore, horizontal through holes for m columns of horizontal straight
feeding pipes are disposed at positions corresponding to the m columns of straight feeding
pipes on the "rectangular stereoscopic seat" in a horizontal transverse direction; furthermore,
vertical through holes for n rows and m columns of vertical filament pressing pipes are
disposed corresponding to the nxm filament pressing pipes configured above the machine
frame; the upper ends of the lower ends of the filament pressing pipes are located in the
filament pressing pipe through holes of the rectangular stereoscopic seat all the time;
therefore, the structure and actions of the present invention are particularly reliable.
[0028] Each row of filament pressing pipes are fixed on an upright rectangular filament pressing pipe tandem arrangement frame; transverse upper and lower side frames are
respectively configured above and under the rectangular stereoscopic seat, such that the
filament pressing pipe tandem arrangement frame can drive m columns of filament pressing
pipes to move up and down on the rectangular stereoscopic seat; furthermore, the filament
pressing pipes are provided thereon with horizontal filament pressing pipe holes; at an initial
position, the filament pressing pipe holes are in communication with the horizontal through
holes of the straight feeding pipes on the rectangular stereoscopic seat; the straight feeding pipe can pass through the two holes;
[0029] With the above structure, the filament pressing pipe and the straight feeding pipe can regularly and orderly move and travel on a track.
[0030] Each rectangular filament pressing pipe tandem arrangement frame is pushed by respective filament pressing pipe pushing mechanism, and moves up and down along the
machine frame; starting from the clamping component adjacent to the machine frame, the
filament pressing pipe tandem arrangement frames move downward one by one; By means of
the power such as a motor and the like, the action of respectively pushing the filament
pressing pipe tandem arrangement frame by respective filament pressing pipe pushing
mechanism to move up and down along the machine frame could be easily realized in the art.
The key is to move downward in an order specified by the present invention. A long fiber
filament is pulled out from the fiber filament spindle in the feeding region. Only such
operation can ensure that one end of the fiber filament is fixed on the machine frame, and the
other end is under stress in one direction, and is gradually, slowly and orderly drawn from the
fiber filament spindle; after one row of filament pressing pipe is pressed in position, the
machine presses the next row, until the entire filament pressing pipes are pre-pressed
completely.
[0031] After the filament pressing pipe moves downward to bend the fiber filament in
a U-shape, the cutoff mechanism cuts off the fiber filament; after the fiber filament is
pre-bent in shape, the fiber filament is stretched tight, and is easy to be cut off according to a
requirement for process steps.
[0032] Each filament pressing pipe is coaxially configured with totally nxm filament
stitching needles capable of moving up and down; the present invention divides n rows of
filament stitching needles into two or more sections; each section of m columns of filament
stitching needles are pushed by a filament stitching needle pushing mechanism to move up
and down along the machine frame, and are pressed downward under the cooperation of a
vibration apparatus; The filament stitching needle pushing mechanism and the vibration
apparatus form a vibration and press mechanism in the present process step of the present
invention. The two actions are conventional actions in industry, and can be realized with
various methods. The present invention inventively applies the two actions to the filament stitching machine the operating efficiency of which is greatly improved.
[00331 In the present invention, the entire n rows are divided into a plurality of sections, for example, a front section and a back section, which could be easily achieved.
However, the operating efficiency is immediately improved by n/2 times. If n is 14, then
operating efficiency will be improved by 7 times. With a simple solution, the efficiency is
immediately amazingly improved to a level far beyond the international advanced level. In
addition, the solution is easy to realize.
[0034] "Each filament pressing pipe is coaxially configured with a filament stitching needle capable of moving up and down; a bottom end of the filament stitching needle is
higher than a bottom end of the filament pressing pipe". Therefore, with the downward move
of the filament stitching needle, it is doubtless that the fiber filament which has been pre-bent
in the U-shape is reliably, precisely and accurately stitched at a predetermined position in a
certain depth under the ground.
[00351 After the stitching, the entire filament stitching needles and the filament
pressing pipes move upward to complete a filament stitching period; and the filament
stitching machine moves the distance of one filament stitching operation region, and enters
the next filament stitching period.
[0036] The filament pressing pipe pushing mechanism and the filament stitching
needle pushing mechanism can be configured on one side or two sides of the machine frame
according to the situation of the overall structure, and can also be configured at the top of the
machine frame to avoid interference positions.
[00371 The fiber filament is an artificial plastic synthetic fiber, and is bunchy.
[00381 Further, the cutoff mechanism performs cutoff in a mechanical manner; n strip-shaped blade strips are transversely disposed with blades facing upward or slantwise
facing the fiber filament; and in a cutoff process step, the blade strips are mechanically lifted.
[00391 Further, the cutoff mechanism performs cutoff in an electric heating manner; n
strip-shaped blade strips are transversely disposed with blades facing the fiber filament; an
electric heating wire is disposed in each blade strip; after being activated, the electric heating
wire heats and achieves a temperature at which the fiber filament can be blown.
[0040] Further, the feeding region and the filament stitching operation region are configured in one of the following three modes:
[0041] The feeding region is located above the filament stitching operation region;
[0042] The feeding region is located in front or back of thefilament stitching operation region; and
[0043] The feeding region is divided into two parts which are respectively located on the left and right of thefilament stitching operation region.
[0044] Further, the filament pressing pipe pushing mechanism adopts a plurality of motors to respectively drive the filament pressing pipe tandem arrangement frames one by one to move up and down along the machine frame;
[0045] Alternatively, one motor drives a main shaft; and the filament pressing pipe tandem arrangement frames are respectively driven one by one to move up and down along the machine frame by means of the idle rotation and real rotation of a plurality of ratchet mechanisms.
[0046] Further, the filament stitching needle pushing mechanism adopts a plurality of motors to respectively drive corresponding sections of filament stitching needles to move up and down along the machine frame; and
[00471 The vibration apparatus generates vibration by means of one or a combination of gravity, a mechanical force, a hydraulic force, and a pneumatic force.
[0048] Further, in the mechanical delivery mode of the fiber filament, the clamping mechanism of the straight feeding pipe is configured as follows:
[0049] The straight feeding pipe consists of an inner pipe and an outer pipe which are sleeved together and can relatively slide; a head of the outer pipe is conical, and a head of the inner pipe is bifurcate; when moving forward, the inner pipe moves forward first, and then the two pipes move forward together; and when moving back, the inner pipe moves back first, and then the two pipes move back together.
[0050] Further, the clamping component on the machine frame is configured as follows:
[0051] The machine frame is provided thereon with a horizontal fixed bar spanning m columns, and is further provided with a transverse batten which is pushed to move up and down by a motor lead screw structure; alternatively,
[00521 The machine frame horizontally extends m fixed vertical blocks, and is further provided with a wooden comb structure which is pushed by a motor lead screw structure and
consists of m movable vertical blocks; and the vertical blocks transversely reciprocate, and
are pairwise clamped face to face or loosened.
[00531 Further, the rectangular stereoscopic seat is made from a plastic material or a metal material, and is integrally formed or is assembled together.
[0054] Further, m is 60, n is 14, and n rows of filament stitching needles are divided into a front section and a back section.
[0055] Further, a height of the straight feeding pipe from the ground is greater than or equal to the sum of a depth of the fiberfilament stitched in the ground and a height of the
fiber filament exposed out of ground.
[00561 The present invention has the following excellent effects and advantages:
[00571 I. From the views of multiple technologies, method, structure and effect, the present invention innovates, changes, and breaks through the prior art in the field of turf
filament stitching machines both here and abroad, and improves the efficiency by multiple
times. For example:
[00581 In the air flow delivery mode, the fiber filament is delivered by blowing the fiber filament with compressed air, thus being quick and saving troubles;
[0059] An n-row m-column filament pressing pipe structure is adopted; the n rows of
filament pressing pipe tandem arrangement frames move downward one by one; the
efficiency is high; and the fiber filament can be easily and orderly drawn from the fiber
filament spindle, such that the present process step can be orderly realized.
[00601 N rows of filament stitching needles are pressed downward by dividing into two or more sections, but not in one row; therefore, the efficiency is improved by multiple
times.
[00611 The filament stitching needles are pressed downward under the cooperation of
the vibration apparatus. The means is never used in the art, and can easily press the fiber
filament in the soil; therefore, more fiber filaments can be pressed at one time, and the means
is an important means to improve thefilament stitching efficiency.
[0062] II. An artificial filament stitching machine which really has a practical use value is provided; the present invention greatly reduces filament stitching time, improves the filament stitching efficiency, reduces economic input, and can quickly construct an artificial filament stitching turf.
[0063] III. The present invention vigorously promotes sport and body building activities such as football and the like, improves competition skills of an athlete, improves the
physical quality and health level of all the people, and enhance the disease resistant ability,
thus facilitating the healthy and rapid development of the social. The present invention is
particularly suitable for constructing a stitched hybrid turf football pitch.

[00791 The fiber filament 6 in the pipe is delivered in two modes: an air flow delivery mode in an initial filament stitching period, and a mechanical delivery mode in a normal
filament stitching period;
[0080] In the air flow delivery mode, the fiber filament 6 is delivered by blowing the fiber filament with compressed air;
[0081] In the mechanical delivery mode, the fiber filament 6 is delivered with an end
head which is cut off in a previous period clamped by a clamping mechanism 5 at an outlet
end of the straight feeding pipe 4 and moving forward together with the pipe; after the fiber
filament is clamped by the clamping component 10 fixed on the machine frame 9, the
clamping mechanism 5 releases the end head, and the straight feeding pipe 4 moves back;
[0082] A rectangular stereoscopic seat 16 is disposed on the machine frame 9; the rectangular stereoscopic seat 16 has a horizontal shape the same as the rectangular turf of a
filament stitching operation, is provided with vertical through holes 14 for n rows and m
columns of vertical filament pressing pipes corresponding to the positions of m columns of
straight feeding pipes 4, and is provided with horizontal through holes 15 for m columns of
horizontal straight feeding pipes; a row of cutoff mechanisms 11 are configured between the
vertical through holes 14 of two rows of transverse filament pressing pipes;
[0083] Each row of filament pressing pipes 7 are fixed on an upright rectangular filament pressing pipe tandem arrangement frame 13; each rectangular filament pressing pipe
tandem arrangement frame 13 is respectively pushed by respective filament pressing pipe
pushing mechanism 17, and moves up and down along the machine frame 9; starting from the
clamping component 10 adjacent to the machine frame 9, the filament pressing pipe tandem
arrangement frames 13 move downward one by one;
[0084] After the filament pressing pipe 7 moves downward to bend the fiberfilament
6 in a U-shape, the cutoff mechanism 11 cuts off the fiber filament 6 in a heating manner or a
mechanical manner;
[00851 Each filament pressing pipe 7 is coaxially configured with a filament stitching needle 8 capable of moving up and down; a bottom end of the filament stitching needle 8 is
higher than a bottom end of the filament pressing pipe 7; n rows of filament stitching needles
8 are in an entire section, or are divided into two (a front section and a back section) or more
sections; each section of m columns of filament stitching needles 8 are pushed by afilament
stitching needle pushing mechanism 12 to synchronously move up and down along the
machine frame 9, and are pressed downward under the cooperation of a vibration apparatus
18;
[00861 The filament stitching needle 8 vibrates and moves downward, penetrates through a lower pipe orifice of the filament pressing pipe 7, and presses the fiber filament 6
to enter the ground G by a determined depth; and the filament stitching operation is

protruding rectangular cutting blade strip is assembled on a strip-shaped blade strip rest at the
position of the fiber filament 6; the latter is easy to maintain, repair and replace.
[0090] The blade of the blade strip can face upward directly, so as to perform cutoff after being lifted; the blade can also be slantwise disposed, so as to generate an inclined slide
action when lifted, such that the fiber filament 6 can be cut off more easily.
[0091] The feeding region and the filament stitching operation region are configured in one or a combination of the following three modes, and the configuration modes can be
selected according to a requirement of a user.
[0092] The feeding region is located above the filament stitching operation region; the configuration mode has the advantages of compact structure and flexible operation and
movement.
[0093] The feeding region is located in front or back of the filament stitching operation region; and the center of gravity is lower, thus facilitating raw material supplement.
[0094] The feeding region is divided into two parts which are respectively located on
the left and right of the filament stitching operation region. The front and back arrangement
does not occupy space; the operation is simple, and the raw material is easy to replace.
[0095] One, or a combination of two, or a combination of the three of the
configuration modes can be adopted as required during configuration, so as to not only satisfy
the filament stitching operation requirement, but also facilitate operation and move flexibly.
[0096] The filament pressing pipe pushing mechanism 17 adopts a plurality of motors
to respectively drive the filament pressing pipe tandem arrangement frames 13 one by one to
move up and down along the machine frame 9; Such design is the simplest and most direct
structure; a program or a switch can be preset, and thefilament pressing pipe tandem
arrangement frames can be activated and deactivated one by one, so as to realize up and
down movement.
[00971 Alternatively, one motor drives a main shaft, and n driven shafts are
respectively engaged one by one to realize forward and reverse rotations, so as to drive the
filament pressing pipe tandem arrangement frames 13 to move up and down along the
machine frame 9. N driven shafts are respectively engaged or disengaged one by one
according to the program, realize forward rotation, stop, reverse rotation with the main shaft,
and drive the filament pressing pipe tandem arrangement frames 13 to move upward, stop,
and move downward. Such structure is more compact, and the filament pressing pipe tandem arrangement frames 13 can be driven to move up and down by one motor.
[0098] The driving of the motor can perform transmission in a belt and chain manner, or in a gear and rack manner, or in a worm gear and worm screw structure manner, and can also use a linear motor, namely the motor drives a lead screw and nut mechanism to perform transmission. All in all, the transmission modes are numerous in the electromechanical field.
[0099] The filament stitching needle pushing mechanism 12 adopts a plurality of motors to respectively drive corresponding sections of filament stitching needles 8 to move up and down along the machine frame 9; and the vibration apparatus 18 generates vibration by means of one or a combination of an electric power, a mechanical force, a hydraulic force, and a pneumatic force.
[00100] In the present process step, the fiber filament is forcibly pressed under the ground; a press and move apparatus converting gravity, electric power, a hydraulic force or a pneumatic force into a mechanical force is conventional; the present patent particularly proposes the method of pressing downward while vibrating; improving a downward pressing effect by means of vibration is a smart but common method. The present invention applies the method to a batch filament stitching apparatus for the first time, and will greatly improve the press and move efficiency. The vibration apparatus may comprise a motor, and a hydraulic or pneumatic vibrator.
[00101] In the original state, the fiber filament is delivered in the pipe by means of air flow delivery; and in the normal filament stitching period, the fiber filament 6 at the outlet end of the straight feeding pipe 4 needs to be clamped by the clamping mechanism 5.
[00102] In the present invention, the straight feeding pipe 4 consists of an inner pipe and an outer pipe which are sleeved together and can relatively slide; a head of the outer pipe is conical, and a head of the inner pipe is bifurcate; when moving forward, the inner pipe moves forward first, and then the bifurcate head of the inner pipe is squeezed and folded by the conical head of the outer pipe, such that the fiber filament 6 in the inner pipe is clamped and fed forward.
[00103] The end head of the fiber filament 6 is clamped by the clamping component fixed on the machine frame; when moving back, the inner pipe moves back first and detaches the squeezing of the conical head of the outer pipe; the bifurcate at the head of the inner pipe does not have a pressure, and thus cannot clamp the fiber filament 6 in the pipe; therefore, only the inner pipe and the outer pipe slide back on the surface of the fiberfilament with one end fixed. The technical solution is smart and is easy to realize in industry. The method can be used as long as standard pipes with appropriate diameters are available.
[00104] The clamping component 10 on the machine frame 9 has two clamping directions: a vertical direction and a horizontal direction; therefore, the clamping is simple,
reliable and easy to realize.
[00105] The machine frame is provided thereon with a horizontal fixed bar spanning m columns, and is further provided with a transverse batten which is pushed to move up and
down by a motor lead screw structure; the transverse batten moves up and down to
synchronously clamp or loosen the end heads of the m columns of fiberfilaments.
[001061 Alternatively, the machine frame 9 horizontally extends m fixed vertical
blocks at corresponding positions, and is further provided with a wooden comb like structure
which is pushed by a motor lead screw structure and consists of m movable vertical blocks;
the wooden comb like structure transversely reciprocates to push the m movable vertical
blocks; and therefore, the vertical blocks are pairwise clamped face to face or loosened.
[001071 The inventor achieves an excellent use effect by selecting the important
parameters of the filament stitching machine as follows: m is 60, and n is 14; n rows of
filament stitching needles 8 are divided into a front second and a back section; and the
filament stitching needles 8 are vibrated and pressed downward in two times.
[001081 According to the experience of the inventor, by dividing the n rows offilament
stitching needles 8 into two or more sections, when the fiber filaments in the second section
start to be pressed after the fiber filaments in the filament pressing pipe 7 in the range of the
first section are pressed in position, the filament stitching needle pushing mechanism 12 and
the vibration apparatus 18 in the first section can start to perform pressing; the two actions
can synchronously performed without influencing the row-by-row filament pressing action in
the second section, and it is unnecessary to wait and activate the filament stitching needles 8
in the first section after the entire filament pressing pipes 7 are all pressed downward
completely; such operations can reduce waiting time, thus improving operation efficiency and
speed.
[00109] The requirements for an artificial ball game field that the gap between n rows
and m columns is 20mm and the exposed height is 20mm can be conveniently realized by the
present invention.
[00110] In addition, the height of the straight feeding pipe 4 from the ground G is greater than or equal to the sum of the depth of the fiber filament 6 stitched in the ground G
and the height of the fiberfilament exposed out of ground. Under such condition, the filament
pressing pipe 7 can normatively pre-press the fiber filament 6 to a position approximate to the
ground G without let or hindrance, then complete the process step of pre-bending the fiber
filament 6 and the final process step of squeezing into the soil.
[00111] If the straight feeding pipe 4 is too low or the U-shaped filament section is too
short, the machine cannot normally operate; and if the straight feeding pipe is too high, the
machine occupies too much space, is unsteady to operate, and is hard to realize the
characteristics of compact mechanism, reliable action, reduced center of gravity and the like.
[00112] The machine frame 9 is a structural frame loaded on a travel mechanism, and can be provided with fixed bars with various lengths and angles at specified positions
according to functional requirements.
[00113] The present invention is not limited to the above embodiments. On the basis of
the technical solution disclosed by the present invention, a person skilled in the art can make
various substitutions and variations to the technical features in the embodiments according to
the disclosed technical content without involving an inventive effort. The substitutions and
variations are all concluded in the protection scope of the present invention.
