Abstract
The utility model relates to a parallel conjugated cam type transverse sealing mechanism in a packaging, bag making and sealing machines. The utility model is characterized in that a cam slide bar structure is adopted, wherein cams of the cam slide bar structure are parallel conjugated cams composed of two curved disc type cams; slide bars are an inner frame type slide bar and an outer frame type slide bar. Two groups of frame type inner slide bars are used in the transverse sealing mechanism, and are respectively embedded in frames on both sides of the outer slide bar. When the utility model is operated, a heat sealing device in the inner slide bar is driven by the cams to be unfolded so as to compact packaging bags so that the packaging bags are heated, pressurized and sealed. The utility model has the advantages of novel design, simple and compact structure, stable operation and easy adjustment and control; because the parallel conjugated cams are adopted, and rotate at uniform speed, the utility model can ensure that the slide bar do not generate rigid impact when the cams rotate at high speed. In addition, vibration can be eliminated so that the work stability is increased. Because the two groups of inner slide bars are adopted, the work efficiency is greatly increased. The utility model can be used in an automatic high-speed bag making machine or a corresponding bag making filling machine.
Description
Technical field
The utility model relates to the parallel conjugate cam type transverse sealing mechanism in a kind of plastic wrapping bag sealer.
Background technology
The mechanical type transverse sealing mechanism of the gear swing-bar mechanism that the horizontal sealing machine structure commonly used in the packing bag capper is made up of pneumatic type, cylinder compound type and cam-type and many slide bars.All there is complex structure in above-mentioned transverse sealing mechanism, makes Installation and Debugging shortcomings such as difficulty and manufacturing cost height and functional reliability be on the low side.Existing a kind of clearance-type transverse sealing mechanism, its cam is the plate-like oval cam, and the rotative speed drop is bigger during work, and the steady rotation speed impact of performance is poor, adopts mono-slide bar heat-sealing structure, and its horizontal sealing work is renderd a service low.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of simple and compact structure is provided, and drive characteristic is good, at the uniform velocity rotate, move and steadily render a service high parallel conjugate cam type transverse sealing mechanism with function admirable and work.
The technical solution of the utility model is to adopt parallel conjugation twin cam batch (-type) horizontal sealing structure, this transverse sealing mechanism comprises slide bar in fulcrum, cam, the frame-like, hot enclosuring device, the outer slide bar of frame-like, flexure strip and pull back spring, interior slide bar is inlaid in the framework of outer slide bar, it is characterized in that cam is the parallel conjugate cam that two curvilinear figure disc camses are formed, and is provided with fulcrum on the cam; Outer slide bar is arranged on the frame, outer slide bar is the outer slide bar of three frame-like, promptly three frameworks are divided into the center cams framework framework that be used for setting-in in slide bar identical with the both sides size, on the framework of its both sides flexure strip is set, parallel conjugate cam is to be provided with in the center cams framework of outer slide bar and with actuating unit to join; Interior slide bar is provided with slide bars in the identical frame-like of two sizes, and interior slide bar front end is provided with hot enclosuring device, and the interior pull back spring of rear end and outer slide bar touches mutually, and hot enclosuring device touches mutually with flexure strip on the outer slide bar, and two interior slide bars are inlaid in respectively in the framework of outer slide bar both sides.The key core component cam of transverse sealing mechanism is to be designed to parallel conjugate cam, and its cam is at the uniform velocity rotated, and by pull back spring enclosed mechanism is contacted all the time with cam; Pull back spring cooperates with cam, make slide bar can accurately be close to camb contour.Hot enclosuring device is a slide bar front end and touch mutually with flexure strip in being inlaid in, and promptly hot enclosuring device is arranged on transverse sealing mechanism and packaging bag contact site.Hot enclosuring device also can be installed on the frame corresponding heat-sealing of transverse sealing mechanism with activity.The horizontal sealing slide bar is under the driving of parallel conjugate cam, and crank motion carries out clamping with the tubular bag material in moving process, its retaining part is embedded with hot enclosuring device, makes packing sealing part melted by heat and makes it to clamp, thereby realize sealing, cam rotates a circle, and finishes sealing of a bag.
In sum, the utility model modern design, simple and compact for structure, motion steadily is easy to regulating control, and low cost of manufacture, use parallel conjugate cam, cam is at the uniform velocity rotated, and in the time of can guaranteeing the cam high speed revolution, slide bar is unlikely to produce rigid shock, simultaneously can eliminate vibration, the stability of raising work is provided with two interior slide bars in the framework of outer slide bar, improved work efficiency greatly.The utility model can be used in the high speed automatic bag-forming machine, or on the corresponding bag stower.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is a plan sketch of the present utility model.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the utility model comprises slide bar 3 in fulcrum 1, cam 2, the frame-like, hot enclosuring device 4, the outer slide bar 6 of frame-like, flexure strip 7 and pull back spring 8, and interior slide bar 3 is inlaid in the framework of outer slide bar 6.It is characterized in that: cam 2 is the parallel conjugate cam that two two curvilinear figure disc camses are formed, and fulcrum 1 is set on the cam 2; Outer slide bar 6 is arranged on the frame 5, be designed to the outer slide bar of three frame-like on the outer slide bar 6, promptly three frameworks are divided into the center cams framework framework that be used for setting-in in slide bar identical with the both sides size, on its two body side frame flexure strip 7 is set, parallel conjugate cam 2 is to be provided with in the center cams framework of outer slide bar 6 and with actuating unit to join.Interior slide bar 3 is designed to slide bars in the identical frame-like of two sizes, and interior slide bar 3 front ends are provided with hot enclosuring device 4, and rear end and outer slide bar 6 interior pull back springs 8 touch mutually, and hot enclosuring device 4 touches mutually with flexure strip 7 on the outer slide bar 6; Two interior slide bars 3 are inlaid in respectively in the framework of outer slide bar 6 both sides.
Principle of work of the present utility model: cam 2 is by the Power train driven rotary, it is reciprocating to drive the interior slide bar 3 that is embedded with hot enclosuring device 4 by it, 3 of interior slide bars are tensioned to cam 2 by pull back spring 8 and contact, make inside and outside slide bar move back and forth and realize that sealing part seals the intermittently folding of hot device during cam 2 rotations, when hot enclosuring device is opened a business, the rectangular bag of filling quantitative article moves down, hot enclosuring device 4 in cam 2 drives in the slide bar 3 closes up, at last the packaging bag envelope is compressed, make the packaging bag pressurization seal that is heated, be right after and carry out next one action again.
