Description

Technical Field

[0001] This utility model relates to the field of tape production technology, specifically a winding device for tape production. Background Technology

[0002] Adhesive tape consists of two parts: a substrate and an adhesive. It bonds two or more unconnected objects together, with an adhesive coating its surface. The earliest adhesives came from animals and plants; in the 19th century, rubber was the main component of adhesives; while modern adhesives widely use various polymers. Adhesives stick things together because their molecules form bonds with the molecules of the objects to be bonded, firmly binding the molecules together. Adhesive tapes can be classified according to their function: high-temperature tapes, double-sided tapes, insulating tapes, specialty tapes, pressure-sensitive tapes, and die-cut tapes, each suited to different industry needs.

[0003] The announcement number is CN215923877U. A winding device for tape production includes a fixed base. A first support frame and a second support frame are fixedly connected to the top two sides of the fixed base, respectively. A bearing seat is fixedly connected to the top of the inner side of the first support frame and the second support frame. A rotating shaft is installed between the two bearing seats. A servo motor corresponding to the rotating shaft is installed on the top of the outer side of the first support frame.

[0004] While the above solution offers many advantages, it also has the following drawbacks: the positioning shaft is locked and fixed using locking bolts to install the winding shaft. However, since there are multiple locking bolts, it is not convenient to install and disassemble the first and second winding shafts. Furthermore, it cannot be used for winding shafts of different lengths, thus reducing the practicality of the device. Utility Model Content

[0005] The purpose of this invention is to provide a winding device for tape production, which solves the problems in the prior art that the installation and disassembly of the first and second winding shafts are not convenient enough, and that the device cannot meet the needs of winding shafts of different lengths.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a winding device for tape production, comprising a base, two fixed discs on the top of the base, an adjustment structure between the two fixed discs and the base, two winding shafts between the two fixed discs, positioning blocks fixedly connected to both ends of the winding shafts, positioning frames sleeved on the outer sides of the two positioning blocks, a rotating shaft fixedly connected to the outer side of one of the positioning frames, one end of the rotating shaft passing through one of the fixed discs and rotatably connected to it, a driving component at one end of the rotating shaft, a threaded rod rotatably connected to one side of the other positioning frame, a threaded sleeve threadedly connected to the outer side of the threaded rod, one end of the threaded sleeve passing through the other fixed disc and rotatably connected to it, a first worm gear fixedly connected to the outer side of the threaded sleeve, a first worm engaging with the outer side of the first worm gear, and a limiting component at one end of the threaded rod.

A limit groove is formed at one end of one of the rotating rods, and a limit rod is fixedly connected to one end of the other rotating rod. The limit rod is set inside the limit groove and slidably connected to one of the rotating rods. The setting of the limit rod and the limit groove can realize that the two rotating rods drive the two fixed disks to rotate synchronously.

[0009] Preferably, two limiting slide rods are provided between the two support plates. The two ends of the limiting slide rods pass through the two support plates and are slidably connected to the two support plates.

When the fixed discs 5 move, they drive the two positioning frames 8 to move through the two rotating shafts 9.
