Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] Please refer to the following: Figures 1 to 3 An automatic feed device for a large-diameter roll edge trimming machine includes a ring plate base 1. The top of the ring plate base 1 has four lower support rollers 4, each with a rotating mechanism. Above the ring plate base 1 are two upper pressure rollers 9, each with a clamping mechanism. A U-shaped frame 10 is fixedly connected to the top of the ring plate base 1. A stepper motor 11 is fixedly connected to the side wall of the U-shaped frame 10. A transmission rod 12 is fixedly connected to the output end of the stepper motor 11. The transmission rod 12 passes through the U-shaped frame 10 and is rotatably connected to it. A swing plate 13 is fixedly connected to the outer wall of the transmission rod 12. A protective cover 14 is fixedly connected to the end of the swing plate 13. A drive motor 15 is fixedly connected to the side wall of the protective cover 14. The output shaft of the drive motor 15 passes through the protective cover 14 and is rotatably connected to it. A saw blade 16 is fixedly connected to the outer wall of the output shaft of the drive motor 15.
[0022] It should be noted that the roll material can be clamped and limited by the two lower support rollers 4 and the upper pressure roller 9. The clamped roll material is cut by driving the saw blade 16 to rotate by the stepper motor 11. The stepper motor 11 has the characteristics of low speed, high torque and precise rotation angle, which has a good cutting effect on the roll material. This application uses the simplest idea and the lowest cost to transform the manual cutting table into an automatic feed cutting table.
[0023] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the rotating mechanism includes a rotating rod 3 that passes through the lower support roller 4 and is fixedly connected to it coaxially. The two ends of the rotating rod 3 are respectively rotatably connected to a fixed block 2 and an L-shaped block 5. Both the fixed block 2 and the L-shaped block 5 are fixedly connected to the ring plate base 1.
[0024] It should be noted that the bottom of the roll material can be supported by the two lower support rollers 4.
[0025] refer to Figure 1 and Figure 2 As shown, the clamping mechanism includes a C-shaped plate 8 rotatably connected to the upper pressure roller 9, a lifting plate 7 fixedly connected to the rear end of the C-shaped plate 8, and a hydraulic rod 6 fixedly connected to the top of the ring plate base 1. The top of the hydraulic rod 6 is fixedly connected to the bottom of the lifting plate 7.
[0026] It should be noted that the upper pressure roller 9 is moved down to clamp the roll material, ensuring the stability of the roll material during subsequent cutting.
[0027] refer to Figure 1 and Figure 2 As shown, the bottom of the fixing block 2 is fixedly connected to the top of the ring plate base 1, and the L-shaped block 5 is fixedly connected to the inner wall of the ring plate base 1.
[0028] refer to Figure 1 and Figure 2 As shown, the upper pressure roller 9 is located directly above the two lower support rollers 4, and the upper pressure roller 9 is located at the midpoint between the two lower support rollers 4.
[0029] It should be noted that the three-point positioning of the roll material by the two lower support rollers 4 and the upper pressure roller 9 ensures the clamping of the roll material.
[0030] refer to Figure 1 and Figure 2 As shown, the saw blade 16 is located inside the protective cover 14.
[0031] It should be noted that: it can protect people.
[0032] refer to Figure 1 and Figure 2 Figure 1 Figure 2 As shown, the bottom of the ring plate base 1 is fixedly connected with four support legs. Each support leg is installed and fixed to the ring plate base 1 by bolts, and each support leg is rotatably connected to a locking universal wheel at its bottom.
[0033] It should be noted that this device can be moved to its destination.
[0034] The working principle of the automatic feed device for the large-diameter roll material cutting machine provided by this utility model is as follows: The operator places the roll material between two sets of lower support rollers 4. The two sets of lower support rollers 4 can support the bottom of the roll material. The hydraulic rod 6 is activated, and the output end of the hydraulic rod 6 drives the lifting plate 7, C-shaped plate 8, and upper pressure roller 9 to move down until the two upper pressure rollers 9 abut against the top of the roll material, thus clamping and fixing the roll material to prevent instability during subsequent cutting. The stepper motor 11 and drive motor 15 are activated. The output shaft of the drive motor 15 drives the saw blade 16 to rotate, and the output end of the stepper motor 11 drives the transmission rod 12 to rotate, so that the swing plate 13, protective cover 14, drive motor 15, and saw blade 16 rotate around the transmission rod 12 as the rotation center, realizing the movement of the saw blade 16 and completing the cutting of the clamped and limited roll material. Moreover, the stepper motor 11 in this application has the characteristics of low speed, high torque, and precise rotation angle, which has a good cutting effect on the roll material.
[0035] The cutting sequence in this application is as follows: load the roll material → start the hydraulic rod 6 to clamp the roll material through the two lower support rollers 4 and the upper pressure roller 9 → start the stepper motor 11 to drive the saw blade 16 to rotate → the saw blade 16 reaches the surface of the roll material (trigger point) → cut the roll → cut the roll end point (trigger point) → reverse and fast back → reset → stop.
[0036] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
