Description

Label paper roll feeding roller

Technical Field

The utility model relates to a tag paper processing field, concretely relates to tag paper roll blowing roller.

Background

In the production process of the label paper, a rolled paper needs to be sleeved on a discharging roller, and in the process of driving the rolled paper to rotate by the discharging roller, label information is printed on the paper in rows in the conveying process of the paper under the action of a conveying roller; after the paper on the emptying roller is used, new rolled paper needs to be sleeved on the emptying roller, and in order to be conveniently sleeved, the paper is usually wrapped on a supporting pipe, and the supporting pipe is directly sleeved on the emptying roller during replacement; however, as the diameter of the discharging roller is generally equal to the inner diameter of the supporting tube, the friction force is large in the process of sleeving the supporting tube on the discharging roller, and the supporting tube is not convenient to mount on the discharging roller; the diameter of the discharging roller is designed to be smaller than the inner diameter of the supporting pipe, the discharging roller is convenient to sleeve, the supporting pipe is not continuous in rotation in the rotating process of the discharging roller, even the supporting pipe cannot rotate, the equipment for printing label information is in reciprocating motion of moving upwards after moving downwards and printing, the supporting pipe can smoothly move to influence the quality of subsequent label information printing, the supporting pipe does not rotate, and paper is easy to break due to the fact that the paper only depends on the traction force of the conveying roller.

In order to achieve the purpose, the technical scheme of the utility model provides a label paper roll emptying roller, which comprises a support frame, a roller body and a tightening mechanism, wherein the roller body is provided with a pore channel along the axial direction of the roller body; every props tight unit and all includes to prop tight piece and prop tight strip, is equipped with the holding tank that holds and prop tight piece on the roller body, is equipped with the slide of intercommunication holding tank and pore on the roller body, props tight strip slide and sets up in the slide, props the inclined plane that is equipped with on the tight strip and can and props the contact of tight pole one end.

The technical effect of the scheme is as follows: the diameter of the roller body is designed to be smaller than the inner diameter of the supporting tube, when the paper roll is replaced, the supporting tube is conveniently sleeved on the roller body after the tensioning rod is pulled out of the pore channel of the roller body, and the friction force is small because a gap exists between the supporting tube and the roller body; after the supporting tube is sleeved on the roller body, the tensioning rod is inserted into the hole channel, so that the tapered end of the tensioning rod is in contact with the inclined plane of the tensioning strip and pushes the tensioning strip and the tensioning block to move in the process of moving the tensioning rod, the tensioning block is in contact with the inner side wall of the supporting tube and supports the supporting tube tightly through the tensioning block, and the supporting tube and the paper are driven to rotate continuously through the tensioning block in the continuous rotating process of the roller body.

Furthermore, the roller body and the tightening rod are both fixed with a limiting disc, and the limiting disc on the tightening rod can be contacted with the roller body. The technical effect of the scheme is as follows: the paper that is convenient for convolute on the stay tube carries on spacingly, prevents that the paper from taking place the skew and influencing subsequent printing in the in-process of conveying.

Furthermore, the side wall of the pore passage is provided with a key groove, and a flat key capable of being embedded into the key groove is fixed on the tightening rod. The technical effect of the scheme is as follows: the roller body rotates, and the tightening rod is driven to rotate smoothly through the flat key.

Furthermore, the number of the tightening units is four, and the four tightening blocks are uniformly distributed along the roller body. The technical effect of the scheme is as follows: the supporting block can stably support the supporting tube.

Further, this internal cavity that is equipped with of roller, the slide runs through the cavity, props and is fixed with the fixture block that is located the cavity on the tightening strip. The technical effect of the scheme is as follows: after the clamping block contacts with the side wall of the cavity, the tensioning strip and the tensioning block are prevented from falling off the roller body.

Further, the distance between the supporting frame which is rotationally connected with the tensioning rod and the roller body is greater than the length of the roller body. The technical effect of the scheme is as follows: the supporting tube is convenient to assemble and disassemble.
