Description
Technical field
The present invention relates generally to field of textile machinery.The present invention is especially but not exclusively to a kind of carding machine.The present invention's
Further embodiment discloses a kind of fastener for being used to be fixed on pin strap on the rod of cover of carding machine.
Background technology
In textile industry, carding machines are in progress carding operation.Combing is to twine fibre bundle and fiber block shredding, solution
Around, and the mechanical process that they can be arranged with parallel direction.It can be also used for deburring and other foreign matters.
Carding process is vital in spinning process, and it determines quality and productivity ratio.Except removing impurity, cotton
Outside the basic function of knot and useless chopped fiber, carding machine by the physical form of textile material leniently and the conversion of thick feeding piece
Into cord, the textile material of cord form may be generally referred to as sliver.Feed piece line density can from about 300 grams ms to
About 800 grams ms are reduced to about 3 grams ms to about 8 grams ms of output sliver.Diameter can be configured in carding machine in about 100mm extremely
(from flat to covered with tooth form pin) roller about changing in the range of 1250mm and with different surfaces characteristic.These
Roller can be run and can be very close to each other with a variety of speed, can be close to a few tenths of a mm.Sliver output rating can be
Change between about 40 meters to about 400 meters per minute.Therefore, the operation of carding machine can be a kind of fine process, can be used for
Processing is referred to as the single fiber thin slice of web, the web may finally be pressed into sliver.
With the development of textile industry, modern textile carding machine has a different carding elements, for example, fixed cover plate and
Swinging cover plate.Basic grooming movement can be carried out between cover plate in comber cylinder (cylinder).Conveyed by roller pin
Fiber often moves towards cover plate, and cover plate can initially resist the motion of fiber, then allows fiber between cover plate and roller pin
Float.The grooming movement can separate single fiber, the fiber for untiing winding, separation and remove the cotton knot and impurity in cover plate
Grain, most fiber is orientated along drum movement direction at last.The cover plate is considered in textile industry relative to the setting of roller
Particularly important one side.The setting means the importance and precise requirements of cover plate processing.
Traditionally, cover plate used in the board-like cotton carding machine of rotary cap can be made by casting.Conventional cover plate includes
Pin cloth part and flat end, the pin cloth part are used for the top for receiving carding clothing, and the flat end is located at each of cover plate
End, for being slidably engaged on the corresponding flexible bending pars convoluta of carding machine.Conventional cover plate there may be the shortcomings that certain, wherein one
A little shortcomings become more serious in the combing of modern high yield.Due to own wt, it is negative that cover plate must endure as sizable bending
Carry.Because cover plate is the beam that is only supported by its end, cover plate may be pulled to roller because of grooming movement.It is intrinsic in order to bear these
The load applied, cover plate should have rotary inertia as big as possible in the case of the limitation that machine construction is applied, this
Played an important role in the design and processing of cover plate.In view of the accuracy and complexity of processing, can by by aluminium or
The aluminium alloy extruded and obtained conventional cover plate with substantial uniform crosssection.
Generally, the cover plate used in carding machine is equipped with pin strap.It is double that pin strap can be further equipped with flexible U shape
Hook, more or less into flexible fabric layer and plastic layer.Pin strap can pass through the fastener and rod of cover phase of such as clip
Attachment.The quality of the carded web of gained is largely by depending on set combing gap (the pin cloth of rod of cover and rolling
Space between the pin cloth of cylinder).According to the material and speed of processing, the combing gap generally can be set to 0.2mm extremely
0.3mm.The carding quality of output can be directly proportional to the combing gap, and narrower gap can always produce more preferable matter
Amount.Therefore, it is very important that accurately setting, which combs gap,.Research has shown that, is adjusted the fluctuation and inaccuracy in gap
There is sizable negative effect to the quality of carding process.In addition to narrower combing gap, along the whole work of rod of cover
It is also very important to set with making even width and comb gap.Comb narrower gap, be more difficult to adjustment comb gap and by its
Keep constant.The narrower gap, may be more sensitive to the temperature change of operating condition.In the operating process of carding machine, according to
The air adjustment of material, technique and inside plants, the operating temperature of rod of cover can raise 10 degrees Celsius to 15 degrees Celsius.Even if
Under such temperature fluctuation, combing gap, which still needs, keeps constant.Therefore, the selection of clamp material may be to combing gap
Change play a crucial role.In conventional carding machine, clip is generally made by steel.
The United States Patent (USP) (hereinafter referred to as " 978 patent ") that numbering is 5898978 discloses a kind of such clip configuration.
Clip disclosed in " 978 patent " is made by steel sheet metal, they be used for by pin strap be fastened on rod of cover and for for
The pin strap changed on rod of cover.These clips have the function of regularly clamping pin strap.By pin strap and rod of cover it
Between establish the connection (positive connection) of shape sealed and carry out fixed pin strap.Generally, clip is used to ensure that in pairs
Clamped respectively on the both sides of rod of cover.Clip has tooth at top, and can be inserted into pin strap, so as to these teeth and pin
Connect to strap shape sealed.
However, compared with the aluminium of rod of cover, steel clamp has different thermal coefficient of expansions.Measurement result shows, with steel clamp
Rod of cover as fastener may deform because temperature raises.Its reason is probably that steel clamp is installed to rod of cover at room temperature
On.When the temperature of the carding machine of factory is increased to operating temperature, mounted rod of cover may recover spill, the comb at center
Manage gap and become big, so as to damage carding quality.One of the main reason for above-mentioned limitation is probably aluminium and use as rod of cover
Make the difference of the thermal coefficient of expansion between the steel clamp of the fastener at the top of cover plate.
In view of the foregoing, some trials have been made, using the material identical material (aluminium) with rod of cover as
Clamp material.This number of being applied is that 1326/CHENP/2003 Indian patent application discloses.However, the holding intensity of pin strap
It is directly proportional to the tensile strength of fastener, and the tensile strength of the aluminium as fastener is very small.Therefore, in operation with
The problem of bending correlation of rod of cover, is still unresolved.
It is contemplated that overcome said one or multiple limitations.
