Description

Technical Field

[0001] This invention relates to the field of tape production equipment, and more particularly to a tape winding device. Background Technology

[0002] Adhesive tape consists of two parts: a substrate and an adhesive. It connects two or more unconnected objects together by bonding them. Its surface is coated with an adhesive. The earliest adhesives came from animals and plants; in the 19th century, rubber was the main component of adhesives; while today, various polymers are widely used. Adhesives can stick things together because their molecules form bonds with the molecules of the objects to be bonded, and these bonds firmly bind the molecules together. The composition of adhesives varies depending on the brand and type, and includes various polymers. Adhesive tape is widely used in daily life.

[0003] Patent application number CN202322542578.7 discloses a self-cutting tape production rewinding machine, including a rewinding mechanism, a detection mechanism, and a cutting mechanism. The rewinding mechanism rewinds the tape. However, this type of device does not tighten the tape during rewinding, resulting in an uneven tape winding surface and bulging during the tape winding process, which affects the actual quality of the tape.

[0004] This invention was developed to address the shortcomings of existing technologies. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a tape winding device.

[0006] This invention can be achieved through the following technical solutions:

[0007] This invention discloses a tape winding device, comprising a frame, with support plates symmetrically fixed on both sides of the frame. Each support plate has a support groove on one side, and a winding shaft is placed between the support grooves. A winding driven gear is fixed on the winding shaft. A sliding plate is also provided on one side of the frame, and a winding motor is fixed on the sliding plate. A winding master gear is fixed to the output end of the winding motor, and the winding master gear can mesh with the winding driven gear. A winding cylinder is also fixed on the frame, with the piston rod end of the winding cylinder fixed to the sliding plate. A positioning shaft is also provided on the frame, with positioning plates rotatably connected to the positioning shaft on both sides. A positioning rod is also provided between the two positioning plates, with a positioning roller rotatably connected to the positioning rod on the positioning rod. A torsion spring is also fixed on the positioning shaft, with the end of the torsion spring fixed to the positioning plate. A positioning gear is also fixed to the end of the positioning shaft. A positioning cylinder is also fixed on the frame, with a positioning rack fixed to the piston rod end of the positioning cylinder, and the positioning rack meshes with the positioning gear. The paper roll is fixed to the take-up shaft. The take-up motor drives the shaft to rotate, winding the tape onto the paper roll. The tape passes under the positioning roller, lifting the roller and wrapping it around the paper roll. A torsion spring drives the positioning roller to press down on the tape, tightening it. Once the tape is tightened and wrapped around the paper roll, the positioning cylinder activates. The piston rod on the positioning cylinder extends, moving the positioning rack. The positioning rack drives the positioning gear to rotate, causing the positioning shaft to rotate. The positioning roller separates from the tape, and the take-up cylinder activates again, extending its piston rod and sliding... After the plate moves and the main winding gear and the driven winding gear separate, the winding shaft is removed, the tape is cut, and the winding shaft with the blank paper roll is placed back on. The winding cylinder is activated, the piston rod on the winding cylinder shortens, and the main winding gear meshes with the driven winding gear on the winding shaft. One end of the tape is pasted onto the paper roll again, and the tape is wound up again. At the same time, the positioning cylinder is activated, the piston rod on the positioning cylinder shortens, and the positioning roller tightens the tape again. This device tightens the tape before winding by the positioning roller, which can avoid the problems of uneven tape winding and bulging.

[0008] Preferably, the frame is further fixed with multiple support rods, which pass through the slide plate and are slidably connected to it.

[0009] Preferably, a limiting rod is also fixed to one side below the positioning shaft. When the positioning shaft rotates, after the positioning shaft rotates a certain angle, the limiting rod contacts the positioning plate and pushes the positioning plate to rotate, thereby separating the positioning roller from the conveyor belt.

[0010] Preferably, a rotating shaft is also provided between the two support plates. A feeding gear is fixed to the end of the rotating shaft, and a feeding cylinder is also fixed on the frame. A feeding rack is fixed to the end of the piston rod of the feeding cylinder, and the feeding rack meshes with the feeding gear. Hooks are also symmetrically fixed on both sides of the rotating shaft. After placing the take-up shaft with the blank paper roll fixed between the two hooks and removing the take-up shaft with the tape wound up, the feeding cylinder is activated, the piston rod of the feeding cylinder shortens, the rotating shaft rotates, and the take-up shaft at the hook position rotates around the rotating shaft. After the take-up shaft on the hook contacts the support plate, it is blocked by the support plate, the take-up shaft separates from the hook, and the take-up shaft slides into the support groove of the support plate.

[0011] Compared with existing technologies, the present invention has the following advantages:

[0012] This device uses positioning rollers to tighten the tape before winding it up, which can avoid problems such as uneven tape winding and bulging. Attached Figure Description

The paper roll is fixed to the take-up shaft 4. The take-up motor 9 drives the take-up shaft 4 to rotate, winding the tape onto the paper roll. The tape passes under the positioning roller 18, lifting the positioning roller 18 and then wrapping it around the paper roll. The torsion spring 19 drives the positioning roller 18 to press down on the tape, tightening it. After the tape is tightened and wrapped around the paper roll, the positioning cylinder 22 is activated. The piston rod on the positioning cylinder 22 extends, the positioning rack 23 moves, and the positioning rack 23 drives the positioning gear 21 to rotate. The positioning shaft 15 rotates, the positioning roller 18 separates from the tape, and the take-up cylinder 8 is activated. The piston rod on the take-up cylinder 8...
