Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tape production equipment, in particular to a PET adhesive tape production winding mechanism. Background Art

[0002] PET tape, also known as PET high-temperature tape, is made of PET double-sided coated with acrylic adhesive. It is suitable for bonding nameplates, decorations, decorative parts, plastics, and rubber. The PET tape is wound into a ring layer through a winding device.

[0003] The existing technology has the following problems:

[0004] 1. The existing PET tape production winding mechanism requires a tensioning device to ensure the tension of the tape and the winding effect during use. The current tensioning device is generally installed together with the roller. The tensioning device needs to be connected and fixed twice with the roller and the corresponding fixing frame. The maintenance operations such as the inspection and replacement of the tensioning device require more time, which is inconvenient and quick maintenance.

[0005] 2. In the existing PET tape production winding mechanism, when the rotating roller contacts the conveyed tape, it generally relies only on anti-slip materials to prevent the tape from deflecting during the conveying process. The protective material only increases the friction. As the use time increases, the anti-slip effect gradually decreases, affecting the stability of the contact between the tape and the rotating roller. Utility Model Content

[0006] In response to the deficiencies in the prior art, the utility model provides a PET tape production winding mechanism, which solves the problem that the current tensioning device needs to be connected and fixed twice to the roller and the corresponding fixing frame, which takes more time to perform maintenance operations such as inspection and replacement of the tensioning device, and is inconvenient for quick maintenance. The roller relies on anti-slip materials to avoid deviation during the tape conveying process. The protective material only increases the friction. As the use time increases, the anti-slip effect gradually decreases, affecting the stability of the contact between the tape and the roller.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a PET tape production winding mechanism, comprising a mounting plate and a tape, wherein the mounting plate is provided with a winding roller, the mounting plate is provided with a first tensioning roller, the mounting plate is provided with a first transition roller, the mounting plate is provided with a second tensioning roller, the mounting plate is provided with a second transition roller, the mounting plate is provided with a third tensioning roller, and the mounting plate is provided with a tensioning groove;

[0008] The first transition roller includes a jacket component and adsorption holes, and the jacket component is provided with adsorption holes;

[0009] The tensioning groove includes a side groove, a first tensioning spring, and a second tensioning spring. The first tensioning spring and the second tensioning spring are arranged in the side groove.

[0010] As a preferred technical solution of the present invention: there are two groups of mounting plates, and both ends of the winding roller, the first transition roller and the second transition roller are rotatably mounted on the two groups of mounting plates respectively.

[0011] As an optimal technical solution of the present invention: three groups of tightening grooves are opened on each group of the mounting plates, side grooves are opened on both sides of the inner wall of the tightening grooves, and a group of first tightening springs and a group of second tightening springs are fixedly installed in each group of the side grooves.

[0012] As an optimal technical solution of the present invention: both ends of the first tensioning roller are connected to short rods and connecting blocks adapted to side grooves are provided on both sides of the short rods. Both ends of the first tensioning roller are installed in corresponding tensioning grooves and correspond to two groups of side grooves.

[0013] As an optimal technical solution of the present invention: the ends of the first tensioning spring and the second tensioning spring are fixedly connected to the connecting blocks on both sides of the short rod at the end of the first tensioning roller, and the installation structure of the second tensioning roller and the third tensioning roller is consistent with that of the first tensioning roller.

[0014] As a preferred technical solution of the present invention: the first tensioning roller, the first transition roller, the second tensioning roller, the second transition roller and the third tensioning roller are all fixed with and covered with a jacket component, and the jacket component is specifically made of silicone.

[0015] Compared with the prior art, the present invention provides a PET tape production and winding mechanism, which has the following beneficial effects:

[0016] 1. A PET tape production winding mechanism is provided with a tensioning groove, a side groove, a first tensioning spring, and a second tensioning spring. The first tensioning roller, the second tensioning roller, and the third tensioning roller are subjected to the force of pulling the tape. According to different force directions, the first tensioning roller, the second tensioning roller, and the third tensioning roller are restricted by the first tensioning spring and the second tensioning spring in the corresponding tensioning groove, which can provide a tensioning effect for the corresponding tensioning rollers. The tensioning mechanism is integrated with the mounting plate, which makes installation, use, and subsequent maintenance more convenient, and has a simple structure, reducing costs.

[0017] 2. This PET tape production and winding mechanism is equipped with a jacket component, adsorption holes, and a tape. During the conveying process, taking the first transition roller as an example, the tape is pressed against the first transition roller to deform the silicone jacket component around the adsorption hole, compressing the internal space of the adsorption hole. Finally, as the tape is continuously conveyed, the force on the jacket component decreases and recovers, causing the adsorption hole to recover, so that the tape is stably adsorbed on the first transition roller. The silicone jacket component provides an anti-slip effect for the conveying of the tape, while the adsorption hole can further stabilize the position of the tape, avoiding the loss of anti-slip effect due to increased use time, affecting the stability between the tape and the corresponding roller. The same applies to the first tensioning roller, the second tensioning roller, the second transition roller, and the third tensioning roller. BRIEF DESCRIPTION OF THE DRAWINGS

During the conveying process of the adhesive tape 9, taking the first transition roller 4 as an example, the adhesive tape 9 contacts the first transition roller 4.
