Detailed ways

The utility model will be further described below in conjunction with the examples, but the protection scope of the utility model is not only limited to the examples.

As shown in Figure 1, a manufacturing equipment for high-reflection welding strips that takes both efficiency and welding effects into consideration, includes a frame 1, and an unwinding portion 2 and a winding portion 3 respectively arranged on both sides of the frame 1, The unwinding part 2 is mainly responsible for unwinding the welding ribbon 10 at a constant speed, and the winding part 3 is used for receiving the welding ribbon 10 at a constant speed after processing. According to the manufacturing process of the welding ribbon 10, a tension control device, a cleaning device 4, a drying device 5 and a processing device 6 are sequentially arranged between the unwinding part 2 and the winding part 3, and the cleaning device 4 is used for cleaning the welding ribbon and drying The device 5 is used to dry the cleaned ribbon 10, and the processing device 6 is used to process the ribbon into required products, which is a core part of the whole manufacturing device.

The unwinding part 2 looks like a big disc, driven by the unwinding driving wheel 11, the unwinding driving wheel 11 is coaxial with the unwinding part 2, the unwinding driving wheel 11 rotates, drives the unwinding part 2 to rotate, and realizes butt welding Belt discharge. Similarly, the winding part 3 is driven by the winding driving wheel 12, and the winding driving wheel 12 rotates to drive the winding part 3 to rotate, so as to realize the winding of the welding strip. Between the unwinding driving wheel 11 and the winding driving wheel 12, a main driving wheel 7 is arranged, and the main driving wheel 7 is positioned at the inside of the frame 1, and is connected with the driving motor 8, and the driving motor 8 drives the main driving wheel 7 to rotate. The unwinding driving wheel 11 , the winding driving wheel 12 and the main driving wheel 7 are engaged with a synchronous belt 9 at the same time. The main drive wheel 7 rotates, and the unwinding drive wheel 11 and the rewinding drive wheel 12 are driven to rotate simultaneously by the synchronous belt 9. The synchronous belt 9 is a common synchronous belt with internal teeth, so driven by the synchronous belt 9, the unwinding drive wheel 11 The same speed as the rewinding drive wheel 12 can realize the same speed of unwinding and rewinding, and better synchronization. And the synchronous belt 9 has the effect of preventing slipping, and the drive is more effective.

The tension control device is located at the upstream of the cleaning device 4. The tension control device is several control rollers 13 arranged up and down. The axes of the control rollers 13 are parallel to the horizontal plane, that is, arranged horizontally. Preferably, the position of the control roller 13 is adjustable, and can move up and down or left and right, so as to adjust the state of the welding ribbon according to the actual situation, so that the welding ribbon can always enter the cleaning device 4 horizontally, smoothly and orderly.

The unwinding section 2 and the winding section 3 can be vertical or horizontal, and what is adopted in Fig. 1 is vertical, that is, their axes are parallel to the horizontal plane. If the horizontal type is adopted, it is preferable to install an angle adjustment device, and the angle adjustment device 14 is arranged at the position of the discharge port of the unwinding part 2 and the position of the feed port of the winding part 3 . Because of the horizontal state, the welding strip is perpendicular to the horizontal plane, and the processing process is best carried out in a horizontal state, so it is necessary to adjust its state before and after processing.

As shown in FIG. 2 , the angle adjusting device 14 includes two rows of adjusting rollers 15 spaced apart from each other. The number and arrangement of each row of adjusting rollers 15 are the same. ° included angle, the axis line of the last adjustment roller 15 is parallel to the horizontal plane, and from the first to the last one, the angle between the axis line of the adjustment roller 15 and the horizontal plane decreases successively. Therefore, during the whole process of the welding ribbon passing through the two rows of adjustment rollers 15, under the action and guidance of the adjustment rollers 15, it will change from a vertical state to a horizontal state, or from a horizontal state to a vertical state, realizing Angle adjustment to ensure the smooth and orderly progress of the entire manufacturing process.

The cutting unit includes a support rod 61, a swing arm 62 connected to the upper end of the support rod 61, and a swing arm 62 connected to the swing arm 62. Knives 63 connected at the end. The swing arm 62 can swing up and down and left and right around its connection point with the support rod 61. As shown in FIG. Therefore, only part of the surface of the welding strip 10 needs special processing, and the processing process also occurs periodically, so the swing arm 62 swings up and down periodically, swings down, contacts with the welding strip, and the welding strip is running The processing of the surface is completed during the process; after the processing is completed, it swings upward; when the next area to be processed comes, the swing arm 62 moves downward again, and this cycle is repeated. The time interval and the swing distance of the swing arm 62 are controlled by the control unit 64 , and these parameters are pre-set in the control unit 64 .

As shown in FIG. 4 , the surface of the cutter 63 has several rows of cutter teeth 631 , and there is a distance between the cutter teeth 631 , and the distance is 0.1-0.6 mm, preferably 0.3-0.5 mm. And the cutter teeth 631 are arranged on the surface of the cutter 63 in a helical, striped or wavy shape. The specific properties are related to the requirements of the welding strip. Of course, no matter what shape it is, it is not limited to the several mentioned in this patent. Any shape, as long as under the action of the cutter teeth 631, the surface of the welding strip can form an uneven structure.

The front end of the knife tooth 631 has an R angle, that is, the front end is a circular arc angle, and the front end refers to the end that acts on the surface of the welding strip. The radius of the R angle is 0.01-0.08mm, preferably 0.02-0.05mm. Therefore, this makes the concave structure formed on the surface of the welding strip an arc-shaped structure.

Preferably, the rear end of the knife tooth 631 also has the same R angle, which makes the surface of the welding strip form a circular arc-shaped concave-convex structure, as shown in Figure 4, which has a higher reflection effect and enhances the photoelectricity. For conversion efficiency, the rear end portion is a position closer to the surface of the cutter 63 than the front end portion.
