[0032] 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.
[0033] Refer to Figure 1 , Figure 3 and Figure 5, an embodiment provided by the present utility model: a plastic product trimming gate device, including a base 1, a fixing frame 3 is fixedly connected to the top of the base 1, a motor one 10 is fixedly connected to the outside of the fixing frame 3, the output end of the motor one 10 is fixedly connected to a threaded rod 11, a moving plate 13 is threadedly connected to the outside of the threaded rod 11, a sliding column 12 is slidably connected to the inner through hole of the moving plate 13, both ends of the sliding column 12 are fixedly connected to the inner wall of the fixing frame 3, two sliding grooves 20 are opened in the fixing frame 3, two sliding plates 19 are fixedly connected to the outside of the moving plate 13, and the outside of the two sliding plates 19 is slidably connected to the inner wall of the corresponding sliding groove 20. A cylinder 4 is fixedly connected to the inside of the moving plate 13, the output end of the cylinder 4 is fixedly connected to a fixing shell 5, a cutter 6 is detachably connected to the inside of the fixing shell 5, two clamping grooves 26 are opened in the cutter 6, two mounting shells 7 are fixedly connected to the inner side of the fixing frame 3, a motor two 14 is fixedly connected to the outside of the mounting shell 7, the output end of the motor two 14 is fixedly connected to a bidirectional screw rod 15, two threaded blocks 16 are threadedly connected to the outside of the bidirectional screw rod 15, a connecting rod 17 is rotatably connected to the inner side of the threaded block 16, the other end of the connecting rod 17 is rotatably connected to a fixing block 18, a pressing plate 8 is fixedly connected to the bottom of the fixing block 18, a rubber plate 9 is fixedly connected to the bottom of the pressing plate 8, and a trimming groove 2 is opened in the base 1.
[0034] Specifically, when the first motor 10 starts, it can drive the threaded rod 11 to rotate. The rotation of the threaded rod 11 drives the moving plate 13 threadedly connected thereto to move horizontally. This makes the movement of the moving plate 13 accurate and stable. The sliding column 12 serves as a stable support, with both ends fixed to the inner wall of the fixed frame 3, providing linear guidance for the movement of the moving plate 13. The inner through-hole of the moving plate 13 is slidably connected to the sliding column 12, ensuring that the moving plate 13 remains stable during movement and does not deviate or shake. At the same time, the chute 20 opened inside the fixed frame 3 cooperates with the sliding plate 19 on the outside of the moving plate 13, further enhancing the smoothness and accuracy of the movement of the moving plate 13. This ensures the accuracy and smoothness of components such as the cylinder 4, the fixed shell 5, and the cutter 6 during movement, thereby improving the cutting accuracy and efficiency. The cylinder 4 drives the cutter 6 to move up and down with its telescopic function. This enables the cutter 6 to accurately position to the gate part of the plastic product for precise cutting operations. When the second motor 14 starts, it can drive the bidirectional screw rod 15 to rotate. When the bidirectional screw rod 15 rotates, the two threaded blocks 16 move towards or away from each other. When the threaded blocks 16 move, through the transmission of the connecting rod 17, the fixed block 18 also moves accordingly. The pressing plate 8 is connected to the bottom of the fixed block 18, and a rubber plate 9 is fixed to the bottom of the pressing plate 8. This ensures that when the fixed block 18 moves, the pressing plate 8 and the rubber plate 9 can closely fit on the plastic product. The material of the rubber plate 9 has certain elasticity and friction, which can provide better fixing effect and anti-slip performance, ensuring that the plastic product does not move or shake during the cutting process. The cutting groove 2 opened inside the base 1 provides a clear working area for the cutting of the plastic product. The size and shape of the cutting groove 2 can be designed and adjusted according to actual needs. When the plastic product is fixed between the pressing plate 8 and the rubber plate 9, its gate part will accurately align with the cutting groove 2, making the cutting operation more precise and convenient.
[0035] Referring to Figure 1 , Figure 6 and Figure 7 , a disassembly component is provided inside the fixed shell 5. The disassembly component is used to disassemble the cutter 6. The disassembly component includes two fixed slots 22. The two fixed slots 22 are opened inside the fixed shell 5. The inner wall of the fixed slot 22 is movably connected with a movable plate 24. One end of the movable plate 24 is fixedly connected with a clamping block 25. The other end of the movable plate 24 is fixedly connected with a pull rod 21. A spring 23 is sleeved outside the pull rod 21. One end of the spring 23 is fixedly connected to the outside of the movable plate 24, and the other end of the spring 23 is fixedly connected to the inner wall of the fixed slot 22. The longitudinal section of the clamping block 25 is square, and the shape of the clamping block 25 matches the shape of the clamping groove 26. The two clamping blocks 25 are inserted and matched with the corresponding clamping grooves 26.
[0036] Specifically, the two fixed slots 22 provide a stable moving space for the movable plate 24 and the spring 23. When it is necessary to disassemble the tool 6, the movable plate 24 moves outward under the pulling of the pull rod 21, driving the clamping block 25 to disengage from the clamping slot 26. This enables the disassembly to be carried out without the need for complex tools or operations, greatly improving the disassembly efficiency. The pull rod 21 serves as an operating handle and drives the movement of the movable plate 24 through external pulling. The spring 23 plays a role in resetting. When the pull rod 21 is released, the elastic force of the spring 23 pushes the movable plate 24 back to its original position, causing the clamping block 25 to be reinserted and engaged with the clamping slot 26. The longitudinal section of the clamping block 25 is square, and this design makes its shape match that of the clamping slot 26. When the clamping block 25 is inserted into the clamping slot 26, their tight fit can prevent the tool 6 from loosening or shifting during operation. This insertion and engagement method not only improves the fixing stability of the tool 6 but also ensures the accuracy and safety of the cutting operation.
[0037] Working principle: First, place the plastic product in the appropriate position on the base 1 so that the gate of the plastic product to be cut is located on the cutting slot 2. The motor two 14 drives the bidirectional screw 15 to rotate, causing the two threaded blocks 16 to move towards or away from each other inside the fixed frame 3. The movement of the threaded block 16 drives the fixed block 18 and the pressing plate 8 to move up and down through the connecting rod 17, and at the same time drives the rubber plate 9 to move up and down, thereby fixing the plastic product. This ensures the accuracy and stability during cutting. Then start the motor one 10, drive the threaded rod 11 to rotate, drive the moving plate 13 to move horizontally along the guide of the sliding column 12 and the sliding plate 19, and at the same time drive the cylinder 4, the fixed shell 5 and the tool 6 to move above the gate part of the plastic product to prepare for cutting.
[0038] When the tool 6 is worn or needs to be replaced, the two pull rods 21 in the disassembly component can be pulled. The movement of the pull rod 21 drives the movable plate 24 and the clamping block 25 to move outward, causing the clamping block 25 to disengage from the clamping slot 26. At this time, the old tool 6 can be easily taken out, and the new tool 6 can be placed into the fixed shell 5. After the pull rod 21 is released, under the action of the spring 23, the movable plate 24 and the clamping block 25 automatically reset, firmly fixing the new tool 6 in the fixed shell 5. Compared with the installation method using multiple bolts in the prior art, it is more convenient, and at the same time, the structural design is reasonable and convenient for people to use.
[0039] 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. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
