Description

Fabric cutter

Technical field

The utility model is related to a kind of cloth process equipment, more specifically, it relates to a kind of fabric cutter.

Background technology

Clothes, refers to the mankind or completes by the mankind to cover body, carrier use cloth（Such as cotton, silk, swan Suede, chemical fibre etc.）The shelter for the various patterns made etc. material, while having different dresses, pattern in different occasions Very many, clothes is having become indispensable thing now.

And clothes is during processing, it is necessary first to which cloth is cut, traditional cutting method is all by cutting Knife is manually cut, and such processing mode causes low in processing efficiency, and machining accuracy is relatively low, for this problem, The Chinese patent of Application No. 201420343713.3, it discloses a kind of Scissoring device of fabric cutter, its process in work In, first material distribution cartridge is placed on material distribution cartridge rack, first cut the cloth on material distribution cartridge after one section around being located at by scissors On rewinding cylinder, then collecting shaft is driven to rotate by drive device, collecting shaft drives rewinding cylinder to rotate, and material distribution cartridge is pulled by cloth Rotation, around being located on rewinding cylinder after the clipped knife cutting of cloth, the hold-down roll of setting can facilitate shearing knife to cut, this The fabric cutter of structure, its automaticity is high, and production efficiency is high.

But when the rotating speed of collecting shaft is too fast, because rewinding cylinder is simply set on collecting shaft, so as to easily lead Cause that relative motion occurs between collecting shaft and rewinding cylinder, ultimately result in fabric cutter and done idle work to a certain extent, cause The waste of the energy.

Utility model content

The purpose of this utility model is to provide a kind of fabric cutter, and it can ensure the rotating speed when collecting shaft to a certain extent Than it is very fast when, few appearance skidding as far as possible between collecting shaft and rewinding cylinder.

Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of fabric cutter, including Rotate to be provided with collecting shaft, the lateral wall of the collecting shaft in frame, the frame and elastic meeting device, the elasticity are set Groove that meeting device includes being arranged on collecting shaft lateral wall and towards collecting shaft axis direction extend, it is slidably arranged in groove Interior and one end can with receive the abutting block that offset of material tube inner wall and be arranged in groove and two ends respectively with to abut block, bottom portion of groove solid Fixed elastic component.

By above-mentioned setting, during processing, rewinding cylinder and collecting shaft interference fits, collecting shaft are rotated, and it can band The dynamic rewinding cylinder being set in thereon is rotated, so as to realize that the cloth that will be cut is wound；And the process rotated in collecting shaft In, it can give elastic one centrifugal force of fitting, so that the direction for abutting block away from groove is slided, i.e. make abutting The inwall of block and rewinding cylinder offsets, and when the velocity of rotation of collecting shaft is constantly accelerated, abuts between block and collecting shaft Pushing against power can also become big, existing so as to effectively prevent from occurring between rewinding cylinder and collecting shaft to a certain extent relatively rotating As；, at this time i.e. can be very easily and after completion is wound, abutting block can be because the effect of elastic component be separated with rewinding cylinder Rewinding cylinder is disassembled from collecting shaft.

It is preferred that, the cambered surface for abutting one end that block and rewinding cylinder offsets to fit with rewinding medial wall of the tube.

By above-mentioned setting, after the contact area increase between block and rewinding cylinder is abutted, block and rewinding cylinder are abutted Between frictional force can also become big, can avoid to a certain extent rewinding cylinder and collecting shaft between relatively rotate.

It is preferred that, the side wall for abutting block is provided with several balls fitted with recess sidewall.

By above-mentioned setting, the presence of ball can make the sliding friction abutted between block side wall and recess sidewall into Rolling friction, i.e., can effectively reduce and abut the frictional force that block is subject in groove in sliding process, and then can effectively reduce Abut frictional force between block and recess sidewall and abutted to abutting the negative function of block centrifugal force, increase between block and rewinding tin Conflict power, prevents relative motion occur between collecting shaft and rewinding cylinder to a certain extent.

It is preferred that, it is provided with and is provided with step block, the frame and turning that collecting shaft is rotatably assorted on the collecting shaft Dynamic set, the turning set inwall is provided with the step groove being rotatably assorted with step block, and the collecting shaft passes through turning set and frame Rotate connection.

By above-mentioned setting, when collecting shaft is installed, first makes collecting shaft complete to be socketed with turning set, then will turn again Dynamic set is fixed in frame, due to the presence of step block, and collecting shaft can not be separated along its axis direction with turning set, but its according to Set can so be relatively rotated to rotate, that is, realize that collecting shaft is rotatably arranged in frame, whole dismounting mode very simple.

It is preferred that, the step block is fixedly installed on the one end of collecting shaft with respect to frame.

By above-mentioned setting, because stage blocks are fixedly installed at one end, therefore, it is possible to very easily realize collecting shaft with turning The mutual socket of dynamic set.

It is preferred that, the turning set is detachably connected with frame.

By above-mentioned setting, when needing dismounting collecting shaft to be repaired or changed, it is only necessary to by turning set from Disassembled in frame, you can realize the separation of collecting shaft and frame, whole disassembly process is very convenient.

It is preferred that, the inwall of the turning set, which is provided with to rotate in several rotation slots, the rotation slot, is provided with side The steel ball contacted with collecting shaft.

By above-mentioned setting, the sliding friction between turning set and collecting shaft can be changed to roll by the presence of steel ball Friction, effectively by the frictional force between turning set and collecting shaft, the abrasion of reduction collecting shaft and turning set effectively improves turning set Service life between collecting shaft.

It is preferred that, it is provided with the shoe cream room communicated with rotation slot on the turning set inwall.

By above-mentioned setting, during collecting shaft is rotated, it can drive steel ball to rotate, but be due to be in shoe cream room Lubricating oil has been expired in storage, and shoe cream room is communicated again with rotation slot, therefore steel ball can take lubricating oil at collecting shaft to, So as to carry out good lubrication between collecting shaft and steel ball, the wear extent of collecting shaft is reduced, collecting shaft is improved Service life.

In summary, the utility model has the advantages that：

1. it can effectively prevent during collecting shaft is rotated occurring between collecting shaft and rewinding cylinder to a certain extent Relative displacement；

2. the dismounting mode between collecting shaft and frame is very convenient；

3. frictional force suffered in collecting shaft rotation process can be reduced, by the wear extent of collecting shaft, collecting shaft is improved Service life.
