[0002] Conveyor belts are widely used in material handling in industrial production. They transport materials from one location to another through continuous operation, offering advantages such as high conveying efficiency and ease of operation. In the production of solar cells, the conveyor belt serves as a crucial material transport component, responsible for delivering solar cells to designated workstations. During long-term operation, direct contact and friction between the metal and the conveyor belt easily leads to wear and burrs on the belt surface. These burrs not only affect the normal use of the belt but can also scratch the surface of the solar cells, reducing product quality and increasing production costs. Furthermore, frequent friction not only affects the belt's appearance but, more importantly, reduces its strength and lifespan, making it prone to breakage and tearing. This, in turn, affects production continuity, increases equipment downtime for maintenance, and reduces production efficiency. Therefore, there is an urgent need for a device that can effectively reduce friction between the belt and metal, extend belt life, and prevent scratches on solar cells. Summary of the Invention

[0003] The purpose of this invention is to provide a device for extending the lifespan and preventing scratches on a feeding belt. By applying Teflon tape to the surface of the belt, direct friction between the metal and the feeding belt is reduced, burrs are avoided from forming on the surface of the feeding belt, thereby reducing the risk of scratches on the surface of the battery cells and effectively extending the service life of the feeding belt, thus solving the problems mentioned in the background art.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "inner", "outer", "horizontal", "vertical", etc. used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the technical solutions of the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0028] Please refer to the following: Figures 1-6The device for extending the life and preventing scratches of the feeding belt includes a belt cross support frame 1 and a belt turntable 2 below it. The belt cross support frame 1 includes two pulleys 1a of equal height and spaced apart. To allow the distance between the two pulleys 1a to be adjusted in both directions to accommodate feeding belts of different lengths, a horizontal sliding groove 1b is provided in the belt cross support frame 1. A slider 1c is movably connected in the horizontal sliding groove 1b. The slider 1c is connected to the pulleys 1a one-to-one through a rotating shaft. One pulley 1a is the driving pulley and the other is the driven pulley. The two sliders 1c are connected to the same spacing adjustment mechanism. The spacing adjustment mechanism includes two "U"-shaped frames 1e with their openings facing each other. The bottom of the opening of each "U"-shaped frame 1e is connected to a slider 1c. The upper part of each "U"-shaped frame 1e is connected to a nut 1f via an elastic element 5. A motor 1h is located between the two nuts 1f and is screwed to two lead screws 1g at both ends of the motor 1h shaft. The two lead screws 1g have opposite spiral directions. By controlling the forward and reverse rotation of the motor 1h, the two "U"-shaped frames 1e are brought closer or further apart, thereby controlling the spacing between the two pulleys 1a.

[0029] Specifically, each pulley 1a has an adjustable belt groove on its outer surface to accommodate feeding belts of different widths. The pulley 1a includes a wheel cylinder 1a-3. The outer surface of the wheel cylinder 1a-3 has a fixed first retaining ring 1a-1 and a movable second retaining ring 1a-2, which are parallel to each other. The belt groove is located between the first retaining ring 1a-1 and the second retaining ring 1a-2. An adjusting post 1a-4 extends from the center of the wheel cylinder 1a-3. An adjusting sleeve 1a-5 is movably connected to the adjusting post 1a-4. A fastening nut 1a-6 is screwed onto the adjusting sleeve 1a-5, with the head of the fastening nut 1a-6 abutting against the adjusting post 1a-4. To fix the adjusting sleeve 1a-5, the adjusting sleeve 1a-5 is connected to the second retaining ring 1a-2 via the "L"-shaped connecting rod 1a-7. When it is necessary to adjust the width of the belt groove, the fastening nut 1a-6 is loosened outward to move away from the adjusting column 1a-4. The adjusting sleeve 1a-5 can move inward and outward on the adjusting column 1a-4, and the distance between the first retaining ring 1a-1 and the second retaining ring 1a-2 changes. When the second retaining ring 1a-2 moves to the required position, the fastening nut 1a-6 is tightened to abut against the adjusting column 1a-4. The adjusting sleeve 1a-5 fixes the position of the second retaining ring 1a-2 via the "L"-shaped connecting rod 1a-7, thus obtaining the belt groove of the required width.

[0030] On the other hand, specifically, the conveyor belt turntable 2 is equipped with ≥2 liftable rollers 2a. Each roller 2a has a different thickness and its central axis is parallel to the central axis of the pulley 1a. The rollers 2a are connected to the conveyor belt turntable 2 through a rotating shaft. The outer circular surface of the rollers 2a is provided with a tape groove, and the width of the tape groove on each roller 2a is different. Therefore, multiple Teflon tape rolls of different sizes can be loaded on the conveyor belt turntable 2, and can be switched as needed to match the tape width required by the feeding belt above.

[0031] The tape turntable 2 is connected to the lifting frame 3 via a rotating shaft. The rotating shaft rotates to position the required tape roll at the top. The lower end of the lifting frame 3 is connected to the telescopic rod 4 via an elastic element 5. By controlling the telescopic rod 4, the lifting frame 3 can be raised and lowered along with the tape turntable 2, ultimately controlling the roller 2a to rise and fall. As the roller 2a rises, the tape roll on it comes into contact with the feeding belt, and the tape roll head is bonded to the feeding belt before being released as the feeding belt moves.

[0032] A further optimization scheme is proposed: the roller 2a includes a cylindrical core 2a-3. The outer surface of the cylindrical core 2a-3 is provided with a fixed third retaining ring 2a-1 and a fourth retaining ring 2a-2. The tape groove is located between the third retaining ring 2a-1 and the fourth retaining ring 2a-2. The fourth retaining ring 2a-2 is transparent and located in front of the third retaining ring 2a-1, which facilitates observation of the amount of tape roll inside and timely replenishment when insufficient.

[0033] In this embodiment, the elastic element 5 is a spring. The spring can adjust the provided tension or pressure by its own deformation, so that the feeding belt is not stretched too tight or too loose by the pulley 1a, and the Teflon tape roll on the roller 2a contacts the surface of the feeding belt with moderate pressure.

[0034] The working process of the feed belt life extension and anti-scratch treatment device provided by this utility model is as follows: Two pulleys 1a stretch the feed belt to be treated. Multiple Teflon tape rolls of different sizes are loaded on the tape turntable 2. The shaft on the lifting frame 3 rotates, and the tape roll to be used is at the top. The telescopic rod 4 works, the tape turntable 2 rises, and the tape roll on the roller 2a contacts the feed belt. After its head end is bonded to the feed belt, the pulley 1a rotates and moves the feed belt. The Teflon tape on the roller 2a is released as the feed belt moves and adheres to the surface of the feed belt. After the feed belt is treated, it can effectively reduce the burrs on the belt surface caused by direct friction between metal materials and the belt during use, reduce the probability of scratches on the surface of the battery cells, and extend the service life of the belt.

[0035] It should be noted that in the present invention, the "connection" not specifically defined can be a fixed connection, a detachable connection, or an integral connection; those skilled in the art can make corresponding adjustments and changes according to the specific application.

[0036] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications and substitutions can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
