A kind of plastics feeding accessory part
Technical field
The utility model relates to a kind of plastics feeding accessory part.
Background technology
In process of production, product needed is encapsulated by plastic paper or plastic bag, and plastic paper or plastic bag in use need cutting, in order to improve cutting efficiency, ensure stability in use, therefore, need in cutting machine, design a kind of plastics feeding accessory part.
Utility model content
For the technical matters of above-mentioned existence, the purpose of this utility model is: propose a kind of plastics feeding accessory part.
Technical solution of the present utility model is achieved in that a kind of plastics feeding accessory part, comprises locating rack, locating rack is provided with close-fitting upper pressure roller and lower compression roller; The both sides of locating rack are provided with vertical loose slot, the two ends of upper pressure roller are provided with movable block, movable block is provided with vertical return springs, movable block and return springs are all arranged in corresponding loose slot; Described locating rack is also provided with helper motor, and helper motor drives lower compression roller to rotate.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Plastics feeding accessory part of the present utility model, upper pressure roller and lower compression roller closely cooperate, and ensure that the stability of feeding, and return springs provides buffering simultaneously, avoids pressure roller and lower compression roller tension to affect feeding; Lower compression roller is driven by helper motor and rotates simultaneously, substantially increases the work efficiency of feeding, adapts to the user demand in enterprise's production.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the block diagram of a kind of plastics feeding accessory part of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described.
As shown in Figure 1, a kind of plastics feeding accessory part described in the utility model, comprises locating rack 41, locating rack 41 is provided with close-fitting upper pressure roller 42 and lower compression roller 43; The both sides of locating rack 41 are provided with vertical loose slot, the two ends of upper pressure roller 42 are provided with movable block 45, movable block 45 is provided with vertical return springs 46, movable block 45 and return springs 46 are all arranged in corresponding loose slot; Described locating rack 41 is also provided with helper motor 44, and helper motor 44 drives lower compression roller 43 to rotate.
During work, plastics pass between upper pressure roller 42 and lower compression roller 43 refer to, upper pressure roller 42 provides buffering by return springs 46, avoid the tension of pressure between pressure roller 42 and lower compression roller 43 to affect feeding; Lower compression roller 43 drives rotation feeding by helper motor 44 simultaneously, substantially increases the work efficiency of feeding.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Plastics feeding accessory part of the present utility model, upper pressure roller and lower compression roller closely cooperate, and ensure that the stability of feeding, and return springs provides buffering simultaneously, avoids pressure roller and lower compression roller tension to affect feeding; Lower compression roller is driven by helper motor and rotates simultaneously, substantially increases the work efficiency of feeding, adapts to the user demand in enterprise's production.
Below be only embody rule example of the present utility model, protection domain of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
