Description

Technical Field

[0001] This utility model relates to the field of rubber processing technology, specifically an adjustable rubber strip cutting machine. Background Technology

[0002] In the manufacturing process of rubber products, in order to carry out mass production of rubber products more rationally and effectively, it is often necessary to control the materials used in rubber products. Therefore, after the rubber mixing process, the processed rubber sheets need to be cut into strips so that their size and weight meet the requirements of subsequent production.

[0003] An investigation revealed that a Chinese utility model patent discloses an adjustable strip width rubber cutting machine (publication number: CN217751547U), which includes a support foot, a worktable fixedly connected to the top of the support foot, a guide column fixedly connected to the top of the worktable, a lifting box fixedly connected to the top of the guide column, a working cavity opened in the lifting box, a lifting mechanism arranged in the working cavity, an adjustment mechanism arranged at the bottom of the lifting mechanism, and the lifting mechanism including a hydraulic lifting rod, an adjustment box, and a guide block.

[0004] Although the aforementioned patent allows the device to adjust the strip width of the cutter by simultaneously moving the cutter towards the center of the bidirectional threaded rod, it can only cut a single rubber strip at a time. After cutting, the remaining material must be manually repositioned under the cutter. This repetitive operation is tedious and time-consuming, resulting in low overall production efficiency and severely restricting the feasibility of mass production.

[0005] Therefore, this utility model provides a rubber strip cutting machine with adjustable strip width to solve the above problems. Utility Model Content

[0017] (III) Beneficial Effects

[0018] The distance between multiple mounting plates is adjusted by setting an adjustment mechanism. The motor drives the bidirectional lead screw in the adjustment mechanism to rotate. Under the drive of the slider, multiple cross-connecting rods rotate, which in turn drive multiple mounting plates to move, thereby adjusting the distance between multiple cutters. Multiple cutters simultaneously cut rubber strips, improving work efficiency. At the same time, the adjustment mechanism can adjust the distance between multiple cutters synchronously, making it easy to operate. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a rubber strip cutting machine with adjustable strip width, such as... Figures 1-5 As shown, the technical solution includes a bracket 1 and a placement frame 2. The placement frame 2 is fixedly connected to the bracket 1. A connecting plate 5 is provided above the placement frame 2, and multiple mounting plates 10 are connected below the connecting plate 5. Each mounting plate 10 has a cutter 6 connected to its bottom. Both ends of the cutter 6 are fixedly connected to the mounting plate 10 by bolts 15. An adjustment mechanism is provided between the multiple mounting plates 10. The adjustment mechanism includes a bidirectional lead screw 11, two sliders 12, and multiple cross components. Each cross component includes two cross-connecting rods 13. The multiple cross components are rotatably connected. The distance between the multiple mounting plates 10 is adjusted by the adjustment mechanism. Driven by the two sliders 12 in the adjustment mechanism, the multiple cross-connecting rods 13 rotate, driving the multiple mounting plates 10 to move, thereby adjusting the distance between the multiple cutters 6. The multiple cutters 6 cut rubber strips simultaneously, improving work efficiency. At the same time, the adjustment mechanism can adjust the distance between the multiple cutters 6 synchronously and ensure that the distance between the cutters 6 remains unchanged no matter how it is adjusted. The operation is simple and convenient.

[0028] A connecting groove 14 is provided at the bottom of the connecting plate 5. A bidirectional lead screw 11 is rotatably connected in the connecting groove 14. Two sliders 12 are symmetrically arranged on the bidirectional lead screw 11, and both sliders 12 are threadedly connected to the bidirectional lead screw 11. The two sliders 12 slide close to the inner wall of the connecting groove 14. The cross assembly is rotatably connected to the mounting plate 10. The end of the connecting rod 13 is rotatably connected to the slider 12. A guide rod 9 is symmetrically provided below the connecting plate 5. Both ends of the guide rod 9 are fixedly connected to the mounting block 8, and multiple mounting blocks 8 are fixedly connected to the bottom of the connecting plate 5. A motor 7 is fixedly connected to the side wall of the connecting plate 5. The output end of the motor 7 is coaxially fixed with the bidirectional lead screw 11.

[0029] When in use, the start motor 7 drives the bidirectional lead screw 11 to rotate. The rotating bidirectional lead screw 11 drives the two sliders 12 to move in opposite directions. When the two sliders 12 approach each other, the sliders 12 drive the cross-connecting rod 13 to rotate. The rotating connecting rod 13 drives the multiple mounting plates 10 to move away from each other, thereby increasing the distance between the cutters 6. When the two sliders 12 move away from each other, the sliders 12 drive the cross-connecting rod 13 to rotate. The rotating connecting rod 13 drives the multiple mounting plates 10 to move closer to each other, thereby decreasing the distance between the cutters 6.

[0030] Multiple mounting plates 10 are slidably connected to the connecting groove 14, and two guide rods 9 slide through the mounting plates 10. The movement of the mounting plates 10 is guided by the two guide rods 9.

[0031] The connecting plate 5 is slidably connected to the bracket 1. A fixed frame 3 is fixedly connected to the top of the bracket 1, and an electric hydraulic cylinder 4 is fixedly connected to the fixed frame 3. The output end of the electric hydraulic cylinder 4 is fixedly connected to the connecting plate 5. When in use, the electric hydraulic cylinder 4 is started to move the connecting plate 5 downward, placing the rubber on the placement frame 2. The moving connecting plate 5 drives the cutter 6 to cut the rubber strips on the placement frame 2. It should be noted that both the motor 7 and the electric hydraulic cylinder 4 are connected to an external power source through wires. The external power source includes a battery for providing power to the motor 7 and the electric hydraulic cylinder 4 and a control switch for controlling their start and stop. The external power source is existing technology. The specific model and specifications of the motor 7 and the electric hydraulic cylinder 4 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts existing technology in this field, so it will not be described in detail.

[0032] In summary: During operation, the starter motor 7 drives the bidirectional lead screw 11 to rotate. The rotating bidirectional lead screw 11 drives the two sliders 12 to move in opposite directions. When the two sliders 12 approach each other, the sliders 12 drive the cross-connecting rod 13 to rotate. The rotating connecting rod 13 drives the multiple mounting plates 10 to move away from each other, thereby increasing the distance between the cutters 6. When the two sliders 12 move away from each other, the sliders 12 drive the cross-connecting rod 13 to rotate. The rotating connecting rod 13 drives the multiple mounting plates 10 to move closer to each other, thereby decreasing the distance between the cutters 6.
