Description

Technical Field

[0001] The utility model relates to a traction roller mechanism, belonging to the field of PET sheet material processing. Background Art

[0002] PET plastic is referred to as PET or PETP. An extruder is often used in the processing of PET sheets. After the extrusion operation of the PET sheet extruder is completed, a traction roller device is required to traction and reel it. In the prior art, the traction roller device of the PET sheet generally uses multiple guide rollers to traction the sheet before reeling it. However, during the conveying process of the sheet, the sheet may overlap partially due to slight differences in the conveying speed or deviations in the conveying angle. After the reeling is completed, the overlapping sheets maintain a shape for a long time, which can easily cause creases on the surface of the PET sheet, and the PET sheet is easy to break from the creases. Therefore, it is necessary to design a traction roller mechanism that can reduce the probability of PET sheet overlap. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a traction roller mechanism to solve the problems raised in the above-mentioned background technology. The present invention can flatten the overlapping PET sheets and reduce the probability of overlapping of PET during the winding process.

[0004] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a traction roller mechanism, including a base plate, a plurality of fixed frames are installed above the base plate, two of the fixed frames form a group, and a conveying roller, a cleaning roller and a winding roller are respectively installed on the fixed frames, the cleaning roller is located between the conveying roller and the winding roller, a mounting frame is installed on the side of the conveying roller away from the cleaning roller, the bottom of the mounting frame is installed on the base plate, a smoothing piece is installed on the mounting frame, a dust collecting piece is installed on the rear side of the cleaning roller, a dust collecting box is installed at the bottom of the base plate, a drawer is installed inside the dust collecting box, and a driving motor is installed on one side of the winding roller.

[0005] Furthermore, the smoothing part includes a guide rod, two guide rods are symmetrically installed on the mounting frame, guide cylinders are installed on the two guide rods, an adjusting rod is installed at the bottom of the guide cylinder, a fixing plate is installed on the adjusting rod, two positioning rods are symmetrically installed at the bottom of the fixing plate, and a reset block is installed on the side of the positioning rod away from the adjusting rod.

[0006] Furthermore, the surface of the adjusting rod is threaded, a screw hole is provided on the fixing plate, and the adjusting rod is threadedly installed in the screw hole.

[0007] Furthermore, a limiting block is installed on the side of the reset block close to the positioning rod, a circular hole is provided on the limiting block, a mounting slot corresponding to the position of the limiting block is provided on the positioning rod, a through hole is provided on the positioning rod, the position of the through hole corresponds to the circular hole, a round rod is installed in the through hole, and the round rod is inserted in the circular hole to install the reset block on the positioning rod.

[0008] Furthermore, the dust suction part includes a dust suction groove, and a plurality of dust suction grooves are opened on the surface of the cleaning roller. A protective cover is installed on the outside of the dust suction groove, a limiting column is installed on one side of the protective cover, and a rubber strip is installed on the other end of the limiting column. The rubber strip is installed on a mounting plate, and the mounting plate is installed in the dust suction groove. A conveying pipe is installed on one side of the cleaning roller, and a fan is installed on the other end of the conveying pipe.

[0009] Furthermore, a transmission pipe is installed at the other end of the fan, and the other end of the transmission pipe is installed on the drawer.

[0010] The beneficial effects of the utility model are as follows: a traction roller mechanism of the utility model adjusts the position between the two fixed plates along the direction of the adjusting rod by rotating the angle of the fixed plate, so that the positioning rod is respectively fitted with the upper side and the lower side of the PET sheet. After the adjustment is completed, the guide cylinder is started to drive the reset block to move repeatedly left and right along the guide rod. The PET sheet at the folded part will be larger than the fixed gap between the two reset blocks. Therefore, while the guide cylinder drives the reset block to move, the thrust generated by the guide cylinder is used to flatten the PET at the folded part, thereby reducing the probability of overlap during the PET winding process.

[0011] The starting directions of the guide cylinders on the two guide rods are opposite, so that the upper and lower reset blocks can cover different parts of the PET during the translation process, which is convenient for timely discovery of the overlapping parts of the PET. The reset blocks are made of soft silicone material to reduce the damage caused by the reset blocks in the process of pushing the PET.

[0012] The fan generates suction, and the surface of the protective cover fits the surface of the PET sheet. The surface of the protective cover has holes. The dust and debris attached to the surface of the PET are sucked into the dust suction groove through the suction force generated by the fan, and then transferred to the drawer for storage by the fan, thereby improving the production quality of PET and preventing debris from adhering to the surface of the PET sheet and scratching the PET sheet during the winding process.
