[0003] In the current PVC material punching machine, the cut pieces of material stick to the bottom strip after being cut on the material strip during the punching process and are not easy to detach on their own. This means that manual peeling is still required during the subsequent winding process, which increases the number of operation steps and reduces production efficiency. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide an automatic feeding and punching machine for PVC materials to solve the problems in the background technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution;

[0020] 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;

[0021] Please see Figures 1-4In this utility model, an automatic feeding and punching machine for PVC material includes a base 1, a bracket 2 fixedly installed on the top of the base 1, a punching device 3 installed on the bracket 2, a moving mold 4 installed at the bottom of the punching device 3, a lower mold 5 installed on the base 1, an unwinding roller 6 and a winding roller 7 installed on the base 1, the unwinding roller 6 and the winding roller 7 being located on both sides of the lower mold 5 respectively, a guide roller group 8 and a drive roller group 9 installed on the base 1, two buffer mechanisms 10 installed between the moving mold 4 and the base 1, a vertical guide rod 11 installed on the bracket 2, a pressure roller 12 installed at the bottom end of the vertical guide rod 11, a spring 13 sleeved on the side of the vertical guide rod 11, and the top end of the spring 13 being fixedly connected to the bracket 2.

[0022] In this invention, the base 1 serves as the device support. During use, the PVC strip roll is mounted onto the unwinding roller 6. Then, the end of the PVC strip is led out and passed sequentially to the right through the guide roller group 8, the moving die 4, the lower die 5, and the interior of the drive roller group 9. The end is then connected to the take-up roller 7. The take-up roller 7 and drive roller group 9 are then started to rotate, driving the PVC strip to move linearly. The punch 3 is then started, driving the moving die 4 to reciprocate vertically in conjunction with the lower die 5 to continuously punch the PVC strip. The drive roller group 9 pulls the PVC strip forward, working with the guide roller group 8 to pull the punching section forward, ensuring a smooth and stable advance and guaranteeing cutting quality. The cut PVC strip is then conveyed forward by the drive roller group 9 and wound up with the take-up roller 7. The vertical guide rod 1... The bottom pressure roller 12 contacts and squeezes the taut, cut bottom strip. Due to the squeezing of the pressure roller 12, the taut PVC strip is deformed, squeezing the cut finished sheet and causing it to fall off, thus achieving automatic material discharge. Furthermore, because the spring 13 supports the vertical guide rod 11, as the tension of the bottom PVC strip changes, the pressure roller 12 and the vertical guide rod 11 will move vertically to compress the spring 13 and achieve adaptive adjustment of the PVC strip tension. This enables the device to automatically unload the cut sheet, reduce subsequent processes, and improve equipment operating efficiency. It solves the problem in the existing PVC material punching machine where the cut sheet sticks to the bottom strip and is difficult to remove on its own, resulting in the need for manual peeling after subsequent winding and low production efficiency.

[0023] Please see Figure 1 and Figure 3 The first limiting ring 111 and the second limiting ring 112 are fixedly installed on the outside of the vertical guide rod 11. The first limiting ring 111 is located above the bracket 2, and the top of the second limiting ring 112 is fixedly connected to the spring 13.

[0024] In this invention, the upward and downward movement of the vertical guide rod 11 is restricted by the first limiting ring 111 and the second limiting ring 112, so that its adaptive adjustment is within a safe range.

[0025] Please see Figure 1 and Figure 2 The buffer mechanism 10 includes an upper guide post 101, a buffer spring 102, and a lower guide post 103. The top end of the upper guide post 101 is fixedly connected to the bottom of the moving mold 4, and the bottom end of the lower guide post 103 is fixedly connected to the base 1. The two ends of the buffer spring 102 are respectively sleeved on the outside of the upper guide post 101 and the lower guide post 103. The top end of the buffer spring 102 is connected to the bottom of the moving mold 4, and the bottom end of the buffer spring 102 is fixedly connected to the base 1.

[0026] In this invention, when the moving mold 4 moves vertically with the drive of the punch 3, the compression buffer spring 102 contracts, thereby driving the upper guide post 101 to move vertically relative to the lower guide post 103. The lower guide post 103 moves vertically to achieve buffering while preventing excessive stroke from causing losses.

[0027] Please see Figure 1 and Figure 4 The base 1 has a longitudinal groove 14, one end of the back of the longitudinal groove 14 is open, and a receiving box 15 is inserted inside the longitudinal groove 14.

[0028] In this utility model, the longitudinal groove 14 facilitates the placement and removal of the receiving box 15, making it convenient for receiving and storing materials.

[0029] Please see Figure 2 The puncher 3 has two vertical rods 31 fixedly installed at its bottom. The bottom end of the vertical rods 31 passes through and slides to the bottom of the moving mold 4. An upper roller 32 is installed at the bottom of the vertical rods 31, and a support roller 16 corresponding to and cooperating with the upper roller 32 is installed on the lower mold 5.

[0030] In this invention, two vertical rods 31 are used to position the upper roller 32, which, together with the support roller 16, positions and tightens the punching part of the PVC strip, thereby achieving stability during cutting and improving cutting accuracy and quality.

[0031] Please see Figure 4 Among them, a handle 151 is installed on one side of the back of the receiving box 15.

[0032] In this utility model, the handle 151 facilitates the loading and unloading of the receiving box 15, making it easy to operate.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
