Specific embodiments
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Embodiment 1
[0025] Please refer to Figures 1-3 , this embodiment provides the following technical solution: A fixture for coating a knife strip, including a substrate 1. Placement boxes 2 are provided on both the front and rear sides of the substrate 1 for placing the knife strips. The placement box 2 is a hollow rectangular structure with one end open, and the open directions of the placement boxes 2 corresponding to both sides are opposite. Through the placement box 2, the knife strips to be coated can be placed.
[0026] In some embodiments, the placement box 2 with the open end facing upward is used to place the knife strips, and the placement boxes 2 with the open ends facing upward on both sides are distributed in an "S" shape on the substrate 1, while the placement box 2 with the open end facing downward mainly serves as a spacer, which can make the knife strips placed on each side have a certain distance, avoiding the distance between adjacent knife strips on each side being too close, resulting in the coating equipment being unable to coat the knife strips in all directions during the coating operation of the knife strips, thereby improving the coating effect of the knife strips.
[0027] One side of the placement box 2 is provided with a fixing mechanism for fixing the knife bar inside the placement box 2. The fixing mechanism includes a pressing plate 3 and a handle 4. The pressing plate 3 is movably arranged inside the placement box 2, and the handle 4 is arranged outside the placement box 2. The end of the handle 4 is fixedly connected with a sliding rod 5. The other end of the sliding rod 5 movably penetrates into the placement box 2 and is fixedly connected with the pressing plate 3. An elastic member 6 is also arranged on the sliding rod 5 outside the placement box 2. Through the pressing plate 3 and the elastic member 6, when taking and placing the knife bar, only by pulling or releasing the handle 4 can the taking and placing operation be completed, replacing the traditional operation method that requires turning bolts to complete the taking and placing of the knife bar. The operation is relatively simple, reducing the physical labor of workers and improving the coating efficiency of the knife bar.
[0028] In order to further facilitate placing the knife bar inside the placement box 2, a guiding plate 7 is fixedly connected to the top of the pressing plate 3. The other end of the guiding plate 7 is closely attached to the inner wall of the placement box 2. Through the guiding plate 7, after the knife bar is placed into the placement box 2, it is avoided that the knife bar is stuck above the pressing plate 3, resulting in the knife bar being unable to be placed inside the placement box 2 and affecting the coating effect of the knife bar.
[0029] In order to further increase the smoothness of the movement of the pressing plate 3, the handle 4 and the sliding rod 5 form a U-shaped structure. When pulling the handle 4 to move, the sliding rods 5 can cooperate with each other to limit the pressing plate 3 and the handle 4, thus facilitating the smooth movement of the pressing plate 3.
[0030] The elastic member 6 includes a first clamping plate 61, a second clamping plate 62 and a return spring 63. The first clamping plate 61 is fixedly arranged on the placement box 2, the second clamping plate 62 is fixedly arranged on the sliding rod 5, and the return spring 63 is sleeved on the sliding rod 5. The two ends of the return spring 63 are respectively fixedly connected with the first clamping plate 61 and the second clamping plate 62. Through the return spring 63, in the initial state, the pressing plate 3 is located in the middle of the placement box 2. Before placing the knife bar, pull the handle 4 to make the pressing plate 3 move away from the substrate 1. The second clamping plate 62 exerts a pulling force on the return spring 63. After the knife bar is placed, release the handle 4, and the return spring 63 resets, so that the pressing plate 3 presses and fixes the knife bar.
[0031] The working principle of the present utility model: When placing the knife bar, first pull the handle 4 on the corresponding placement box 2, which can make the pressing plate 3 move away from the substrate 1. At the same time, when the handle 4 moves outwards, the sliding rod 5 drives the second clamping plate 62 to move outwards, thus exerting an outward pulling force on the return spring 63. After the knife bar is placed inside the placement box 2, release the handle 4. Under the action of the return spring 63, the pressing plate 3 moves towards the substrate 1, so that the pressing plate 3 fixes the knife bar inside the placement box 2. Thus, when the substrate 1 rotates around its axis, the coating equipment coats the knife bar.
[0032] Embodiment 2
[0033] Please refer to Figures 4-5
[0034] In some embodiments, the pull rod 8 is arranged along the length direction of the substrate 1, mainly for connecting with the handle 4 on each placement box 2. By driving the movement of the pull rod 8, all the handles 4 can move synchronously.
[0035] The fixing member 9 includes a clamping block 91. One end of the clamping block 91 is provided with a first hole slot for the pull rod 8 to pass through. The clamping block 91 is provided with a locking bolt 92 for fixing the pull rod 8. The other end of the clamping block 91 is provided with a second hole slot for the handle 4 to pass through. The clamping block 91 is fixedly connected with the handle 4. Through the clamping block 91, it is convenient to connect the handle 4 with the pull rod 8 and to disassemble and assemble the clamping block 91 on the pull rod 8.
[0036] It further includes a locking assembly 11 for locking and fixing the pull rod 8. The locking assembly 11 includes a first positioning plate 111 and a second positioning plate 113. The first positioning plate 111 is fixedly arranged on the pull rod 8. The first positioning plate 111 is provided with a first positioning groove 112. The second positioning plate 113 is fixedly arranged on the placement box 2. The second positioning plate 113 is provided with a second positioning groove 114 adapted to the first positioning groove 112. Through the first positioning plate 111 and the second positioning plate 113, after pulling the handle 10 to make the pull rod 8 pull all the handles 4 to move outwards, the position of the pull rod 8 can be positioned, so that the hands of the worker can be liberated, and the tool bars in the placement box 2 can be taken and placed in sequence, further improving the convenience of the device and facilitating the operation of the worker.
[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
