Description

A kind of new shaftless moves back mechanism of paper

Technical field

The utility model is related to paper product production technical field, especially a kind of new shaftless moves back mechanism of paper.

Background technology

In paper roll production process, the lateral position of paper roll is adjusted according to actual conditions, paper roll support device is such as at present Shown in Fig. 1, the pressure of the paper roll axle sleeve 4 in this structure is all supported by thimble 2, and during paper roll is traversing, cylinder 3 is logical It crosses connecting seat 1 and horizontal force is passed into thimble 2, thimble 2 should bear the pressure of paper roll axle sleeve 4 at this time, bear to come again From the horizontal force of connecting seat 1, this structure stress situation is complicated, to the part processing request of structure and matching requirements all very Height, processing cost and assembly cost and maintenance cost are also very high.

Utility model content

In order to solve the above-mentioned technical problem, it is lower to provide a kind of more reasonable structure, processing and maintenance cost for the utility model New shaftless move back mechanism of paper.

To achieve these goals, the utility model adopts the following technical solution：

The new shaftless, which moves back mechanism of paper, includes two pedestals below two stents and stent, two stents respectively with paper The both ends of spool set are connected by bearing, and respectively there are one the push-pull device at fixed for being used to push and pull stent, branch for connection in the outside of two stents Sliding contact between the bottom surface of frame and the upper surface of pedestal, stent can move left and right under the push-and-pull action power of push-pull device at fixed, from And paper roll axle sleeve is driven to move.

Stress is more between the new shaftless of the utility model moves back mechanism of paper all parts due to the above structure, Rationally, processing request and the matching requirements of part are reduced, so as to reduce processing cost and assembly cost and maintenance cost.

Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained shall fall within the protection scope of the present invention.

Include as shown in Fig. 2, the new shaftless of the utility model embodiment moves back mechanism of paper under two stents 5 and stent 5 Two pedestals 8 of side, two stents 5 are connected respectively with the both ends of paper roll axle sleeve 4 by bearing 7, and the outside of two stents 5 respectively connects It connecing there are one for pushing and pulling the push-pull device at fixed of stent 5, process is more stable in order to push and pull, and wherein the push-pull device at fixed of one end is cylinder 6, The push-pull device at fixed of the other end is motor 9 and threaded rod 10, and sliding contact between the bottom surface of stent 5 and the upper surface of pedestal 8 is propped up Frame 5 can move left and right under the push-and-pull action power of motor 9 and threaded rod 10 and cylinder 6, so as to which paper roll axle sleeve 4 be driven to move, Ensure that paper roll axle sleeve 4 is not fallen off with this.

The operation principle that the new shaftless of the embodiment of the utility model moves back mechanism of paper is：Paper roll axle sleeve under normal circumstances 4 rotate with the bearing in stent 5, when paper roll needs traversing to the left（Compared with Fig. 2）, start motor 9 and cylinder 6, electricity Machine 9 pulls the stent 5 in left side to be moved to the left by threaded rod 10, and cylinder 6 promotes the stent 5 on right side to be moved to the left, and similarly, works as paper When volume needs traversing to the right（Compared with Fig. 2）, start motor 9, motor 9 by threaded rod 10 promote left side stent 5 to It moves right, cylinder 6 pulls the stent 5 on right side to move right by losing heart automatically, due to the bottom surface of stent 5 and the upper table of pedestal 8 It is sliding contact between face, during movement, stent 5 and 4 position of paper roll axle sleeve do not change, therefore each component Between loss it is very small.

Cylinder 6 and motor 9（Containing threaded rod 10）Play the role of in above-mentioned operation principle be push and pull effect, can be with The mechanism of oil cylinder or other push-and-pulls having the function of is replaced with according to actual needs, and similary can rise reaches said effect.

Stress is more reasonable between the new shaftless of the utility model moves back mechanism of paper all parts, reduces adding for part Work requirement and matching requirements, so as to reduce processing cost and assembly cost and maintenance cost.

The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention, Every equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is directly or indirectly transported Used in other related technical areas, it is equally included in the patent within the scope of the utility model.

Claims (1)

1. a kind of new shaftless moves back mechanism of paper, including two pedestals below two stents and stent, it is characterised in that：Two Both ends of the stent respectively with paper roll axle sleeve are connected by bearing, and respectively there are one be used to push and pull stent for connection in the outside of two stents Push-pull device at fixed, sliding contact between the bottom surface of stent and the upper surface of pedestal, stent can be under the push-and-pull action power of push-pull device at fixed It moves left and right, so as to which paper roll axle sleeve be driven to move.
