Description

Technical Field

[0001] This utility model relates to the field of belt processing equipment technology, and in particular to a belt cutting device. Background Technology

[0002] Belt processing requires cutting, which involves cutting the long belt into the required length, wrapping the cut portion into a loop, and connecting and securing the two ends to produce the finished belt. During the cutting process, the belt needs to be pressed and secured to prevent displacement during cutting, effectively improving the stability of the belt during cutting.

[0003] However, in actual operation, since the uncut long belt needs to be pulled along the processing table to ensure that the cutting part can move to the position below the cutter, in order to ensure the stability of the belt during pulling, a limiting structure needs to be set on both sides of the belt to prevent the material from deviating during feeding. When the belt is pulled, there is friction between the lower surface of the belt and the upper surface of the processing table, and there is also friction between the limiting structure and the side of the belt. Therefore, the probability of wear on the lower surface and side of the belt is increased, which significantly reduces the protection effect on the belt. To this end, we propose a belt cutting device that can reduce the probability of wear on the lower surface and side of the belt. Utility Model Content

[0028] Example

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, the present invention proposes a belt cutting device, including a processing table 1. A table support 6 is fixedly installed at the bottom of the processing table 1, which supports the processing table 1 on the ground, improving the stability of the device after placement. Two positioning frames 4 are fixedly installed on the top of the processing table 1. The positioning frames 4 press and position the belt to be cut, improving its stability during cutting. A cutting frame 5 is fixedly mounted on the top of the processing table 1, located between the two positioning frames 4. When the cutter 53 installed on the cutting frame 5 moves down and penetrates the belt, the belt can be cut. The processing table 1 has two first elongated openings 12 and two second elongated openings 13. Several support rollers 3 are rotatably installed inside the first elongated openings 12 and the second elongated openings 13. When the belt is pulled along the processing table 1 for feeding, the support rollers 3 are used to cut the belt. Several support rollers 3 provide stable support to the lower surface of the belt, maintaining a certain distance between the lower surface of the belt and the top of the processing table 1. This reduces the friction between the lower surface of the belt and the upper surface of the processing table 1, effectively reducing the probability of wear on the lower surface of the belt. Several horizontal limiters 2 are fixedly installed on the top of the processing table 1. Several sets of horizontal limiters 2 are set on both sides of the first elongated opening 12 and the second elongated opening 13. When the belt is fed and pulled along the processing table 1, the horizontal limiters 2 form a limit on both sides of the belt, preventing the belt from deviating during feeding and ensuring its stability during cutting. The rubber wheel 23 rotatably installed on the horizontal limiter 2 can prevent the side of the belt from directly contacting the horizontal limiter 2, thus reducing the probability of wear on the side of the belt and effectively improving the protection effect of the belt.

[0030] like Figures 1-3 As shown, in order to meet the horizontal limiting requirements for belts of different widths, the positioning seat 21 on the horizontal limiter 2 is fixedly installed on the top of the processing table 1. A connecting frame 24 is slidably installed on the top of the positioning seat 21. A limiting frame 22 is fixedly installed on one end of the connecting frame 24. Several rubber wheels 23 are rotatably installed on the limiting frame 22. When the belt is fed and pulled along the processing table 1, the connecting frame 24 is adjusted horizontally according to the width of the belt to ensure that the limiting frames 22 on both sides of the belt can approach the belt, so that the rubber wheels 23 can contact the side of the belt. Therefore, it can limit the horizontal width of belts of different widths and improve the applicability of the device.

[0031] Furthermore, in order to improve the stability of the adjusted limiting frame 22, a screw limiting plate 26 is fixedly installed on the top of the positioning seat 21. An adjusting screw 25 is threaded onto the screw limiting plate 26. One end of the adjusting screw 25 is rotatably connected to the matching connecting frame 24. By rotating the adjusting screw 25, the limiting frame 22 can be moved horizontally. When the limiting frame 22 is adjusted to the specified position, it is positioned horizontally by adjusting the screw 25, which effectively improves its stability after adjustment.

[0032] Secondly, in order to improve the stability of the connection between the limiting frame 22 and the positioning seat 21, two telescopic rods 27 are fixedly installed on the side of the limiting frame 22 near the positioning seat 21. The end of the telescopic rod 27 away from the limiting frame 22 is inserted into the matching positioning seat 21 and movably connected to it. When the limiting frame 22 is adjusted laterally, the telescopic rod 27 extends and retracts along the through groove inside the positioning seat 21 to ensure that the bottom of the limiting frame 22 can maintain a stable connection with the positioning seat 21.

[0033] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in order to facilitate the pressing and positioning of the belt, a positioning plate 42 is slidably installed on the positioning frame 4. A first cylinder 41 is fixedly installed on the top of the positioning frame 4. The output end of the first cylinder 41 is fixedly connected to the top of the positioning plate 42. The positioning plate 42 can be driven to move up and down by the first cylinder 41. When the positioning plate 42 moves downward and comes into close contact with the upper surface of the belt, the belt can be pressed and positioned.

[0034] Furthermore, to facilitate belt cutting, several suspensions 51 are fixedly installed on the cutting frame 5. The ends of the suspensions 51 away from the cutting frame 5 are all fixed to the top of the matching positioning frame 4 by bolts, ensuring that the cutting frame 5 can be firmly suspended above the processing table 1. A cutter 53 is slidably installed on the cutting frame 5. A second cylinder 52 is fixedly installed on the top of the cutting frame 5. The output end of the second cylinder 52 is fixedly connected to the blade holder of the cutter 53. The second cylinder 52 can drive the cutter 53 to move up and down. When the cutter 53 moves down and penetrates the belt, the belt can be cut.

[0035] Secondly, in order to reduce the probability of wear on the belt pressing and cutting parts, a first rubber pad 14 and a second rubber pad 15 are fixedly installed on the top of the processing table 1. The first rubber pad 14 is located on both sides below the cutter 53. When the cutter 53 applies pressure to the belt, the first rubber pad 14 can buffer and protect the bottom of the belt near the cut, thus reducing the probability of wear on the belt near the cut. The second rubber pad 15 is located below the positioning plate 42. When the positioning plate 42 presses and positions the belt, the second rubber pad 15 buffers and protects the lower surface of the belt positioning part, thus reducing the probability of wear on the lower surface of the belt positioning part.

[0036] It is worth noting that, in order to ensure that the cutter 53 can completely cut the belt, a V-groove 11 is cut on the top of the processing table 1 and below the cutter 53. The V-groove 11 is located between the two first rubber pads 14. When the cutter 53 moves down and cuts the belt, when the blade of the cutter 53 is inserted into the V-groove 11, it can be ensured that the cutter 53 can completely penetrate the belt and ensure that the belt can be completely cut.

[0037] In this embodiment, during the feeding and pulling of the belt along the processing table 1, several support rollers 3 support the lower surface of the belt, ensuring a certain distance between the lower surface of the belt and the upper surface of the processing table 1. This prevents friction between the lower surface of the belt and the upper surface of the processing table 1. The rolling support rollers 3 reduce the frictional resistance experienced by the belt during pulling, saving effort during feeding and reducing the probability of wear on the lower surface of the belt. Horizontal limiters 2 installed on both sides of the belt limit its horizontal movement, preventing belt deviation during feeding and avoiding cut deviation during subsequent cutting, thus improving cutting efficiency. Operational stability: The rubber wheel 23, which is rotatably mounted on the horizontal limiter 2, prevents the side of the belt from directly contacting the horizontal limiter 2, thereby reducing the frictional resistance on the side of the belt and lowering the probability of wear on the side of the belt. After the belt has finished loading, the first cylinder 41 drives the two positioning plates 42 to move downward. When the positioning plates 42 are in close contact with the upper surface of the belt, they can press and position the belt to prevent movement during cutting and improve the stability of the cutting operation. The second cylinder 52 drives the cutter 53 to move downward. When the blade of the cutter 53 penetrates the belt and inserts into the V-groove 11, the belt can be completely cut.

[0038] The above specific embodiments are merely several optional embodiments of this utility model.
