Description

Technical Field

[0001] This utility model belongs to the technical field of pearl cotton processing equipment, specifically a pearl cotton slitting device. Background Technology

[0002] Pearl cotton is a type of polyethylene foam. Compared with ordinary foam, it overcomes the disadvantages of being fragile, deformable, and having poor resilience. Therefore, it provides better protection when used for packaging various products, and has gradually taken over the application scenarios of traditional foam packaging. In the processing of pearl cotton, slitting is one of the common steps. According to a search, patent document CN218364940U discloses a pearl cotton slitting device. This device places the pearl cotton to be slitting on top of a connecting plate, then rotates a rotating wheel. This causes a threaded rod to move a mounting bracket outside a limiting rod. As the mounting bracket moves, it moves a rotating drum, which then presses against the top of the pearl cotton, thus fixing it in place. This solves the problem that if the pearl cotton cannot be fixed during the slitting process, the cut pearl cotton will be of inconsistent sizes, leading to waste and economic losses, failing to meet the current user needs.

[0003] The aforementioned comparative documents also have the following shortcomings: the method of fixing the pearl cotton by pressing it from above with rollers is convenient for pushing the pearl cotton to move later, but its stabilizing effect is obviously insufficient. During the cutting process, the cutting force can easily cause the rollers to roll and the pearl cotton to shift, resulting in the yield rate still needing to be improved. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a pearl cotton slitting device, which solves the problem that the existing pearl cotton slitting devices do not have a sufficient stabilizing effect on pearl cotton.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pearl cotton slitting device, including a cutting workbench, a U-shaped mounting bracket installed on one side of the top of the cutting workbench, and mounting grooves reserved at both ends of one side of the U-shaped mounting bracket, an electric push rod installed at the top inside the mounting groove, and a cutting head connected to the output end of the electric push rod. Threaded rods are installed at both ends of the top of the cutting workbench away from the U-shaped mounting bracket, and guide blocks are installed on the cutting workbench on the side of the threaded rods. An installation chamber is fitted on the outer wall of the threaded rods and guide blocks, and a conveyor belt assembly is installed inside the installation chamber. Through holes are reserved at the middle positions of both ends of the cutting workbench. An extrusion block is installed on the side of the cutting head near the cutting workbench. A guide rod is installed on the inner side wall of the U-shaped mounting bracket. An active mechanism for extruding the conveyor belt assembly is provided on the guide rod.

[0006] As a further embodiment of this utility model: the mounting chamber and the threaded rod are threadedly connected, and the mounting chamber and the guide block are slidably connected.

[0007] As a further embodiment of this utility model: the cross-sectional shape of the extrusion block is trapezoidal, and the extrusion block and the cutting head are manufactured as a single unit.

[0008] As a further embodiment of this utility model: the movable mechanism includes two sets of movable mounting blocks, the movable mounting blocks are sleeved on the outside of the guide rod, one end of the movable mounting block is penetrated by a double-headed positive and negative screw rod, and the double-headed positive and negative screw rod penetrates the U-shaped mounting frame, one side of the movable mounting block is penetrated by a movable component, and the end of the movable component away from the U-shaped mounting frame is equipped with a compression limiting component, and a spring is connected between the movable component and the movable mounting block.

[0009] As a further embodiment of this utility model: the movable mounting block and the guide rod are slidably connected, and the movable mounting block and the double-ended positive and negative lead screws are threadedly connected.

[0010] As a further embodiment of this utility model: the movable part and the movable mounting block are slidably connected, and the end of the movable part near the extrusion block is rounded.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The cutting head is equipped with a squeezing block. When the electric push rod drives the cutting head to move downward to cut the pearl cotton, the squeezing block will squeeze and adhere the corresponding conveyor belt assembly through the squeezing movable part and the squeezing restricting part. This provides sufficient friction to restrict the rotation of the conveyor belt assembly, thereby avoiding insufficient stability of the pearl cotton in the subsequent cutting process and ensuring the yield of cut products. 2. By sliding the two sets of movable mounting blocks to the guide rod and threading the two sets of movable mounting blocks to the double-headed positive and negative screws, the extrusion limiting parts extend into the inside of the through hole. This allows the two sets of extrusion limiting parts to cooperate with each other to limit the sides of the pearl cotton during use. The width limiting size can be adjusted according to different batches of pearl cotton, making it easier for workers to quickly position and place pearl cotton of different widths.

[0014] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0015] like Figures 1-6 As shown, this utility model provides a technical solution: A pearl cotton slitting device includes a cutting workbench 1, a U-shaped mounting bracket 2 is installed on one side of the top of the cutting workbench 1, and mounting grooves 3 are reserved at both ends of one side of the U-shaped mounting bracket 2. An electric push rod 4 is installed at the top inside the mounting groove 3, and the output end of the electric push rod 4 is connected to a cutting head 5. The stability of the cutting head 5 and the U-shaped mounting bracket 2 during movement can be further ensured by adding a sliding groove slider. Threaded rods 6 are installed at both ends of the top of the cutting workbench 1 away from the U-shaped mounting bracket 2, and guide blocks 7 are installed on the cutting workbench 1 on the side of the threaded rods 6. The outer walls of the threaded rods 6 and guide blocks 7 are fitted with mounting chambers 8, and the inside of the mounting chambers 8 is fitted with conveyor belt assembly 9. The conveyor belt assembly 9 is the same as the existing conveyor belt, but it does not have autonomous driving force. Its outer ring part can complete the conveying action under external action. The mounting chamber 8 and the threaded rod 6 are threadedly connected, and the mounting chamber 8 and the guide block 7 are slidably connected. The threaded rod 6 is connected to the cutting worktable 1 through a thrust bearing. In use, the operator can place the pearl cotton on the cutting worktable 1 and then rotate the threaded rod 6 to drive the mounting chamber 8 and the conveyor belt assembly 9 on it to move downward until the conveyor belt assembly 9 is in contact with the top of the pearl cotton, thus providing initial stabilization for the pearl cotton. At the same time, the operator can push the pearl cotton laterally, and the conveyor belt assembly 9 will make corresponding conveying actions, which facilitates the execution of continuous cutting tasks. Through holes 10 are reserved at the middle positions of both ends of the cutting workbench 1. An extrusion block 11 is installed on the side of the cutting head 5 near the cutting workbench 1. A guide rod 12 is installed on the inner side wall of the U-shaped mounting frame 2. An active mechanism for extruding the conveyor belt assembly 9 is provided on the guide rod 12. The active mechanism includes two sets of active mounting blocks 13. The active mounting blocks 13 are sleeved on the outside of the guide rod 12. A double-headed positive and negative screw 14 passes through one end of the active mounting block 13 and passes through the U-shaped mounting frame 2. A movable part 15 passes through one side of the active mounting block 13, and an extrusion limiting part 16 is installed at the end of the active part 15 away from the U-shaped mounting frame 2. A spring 17 is connected between the active part 15 and the active mounting block 13. The extrusion limiting part 16 always remains inside the through hole 10. When placing pearl cotton, the operator can place the pearl cotton between the two sets of extrusion limiting parts 16 to achieve quick positioning and placement, while further ensuring stability in the subsequent cutting process. The movable mounting block 13 is slidably connected to the guide rod 12, and the movable mounting block 13 is threadedly connected to the double-headed positive and negative screw 14. When the double-headed positive and negative screw 14 rotates, the two sets of movable mounting blocks 13 can complete the opposite movement task, thereby allowing the distance between the two sets of extrusion limiting parts 16 to be adjusted, which facilitates the limiting and positioning of pearl cotton of different widths. The extrusion block 11 has a trapezoidal cross-sectional shape and is integrally manufactured with the cutting head 5. The movable part 15 and the movable mounting block 13 are slidably connected, and the end of the movable part 15 near the extrusion block 11 is rounded. This allows the inclined part of the extrusion block 11 to first extrude the two sets of movable parts 15 when the cutting head 5 is about to descend and begin the cutting task. The movable part 15 then drives the extrusion limiting part 16 to move toward the corresponding conveyor belt assembly 9 until the extrusion limiting part 16 and the conveyor belt assembly 9 are fully pressed together and generate sufficient friction. At this time, the resistance of the conveyor belt assembly 9 to the conveying action is greatly increased. In the subsequent cutting task, the extrusion block 11 always maintains the extrusion of the movable part 15, so that the conveyor belt assembly 9 can fully compress the pearl cotton and prevent it from easily shifting during subsequent cutting. In application, the side of the extrusion limiting part 16 near the conveyor belt assembly 9 can be made into a wear-resistant rubber layer.

[0016] The working principle of this utility model is as follows: The device is powered by an external power source. When in use, the double-headed positive and negative screw 14 is rotated. As mentioned above, the two sets of movable mounting blocks 13 can move in opposite directions, and the distance between the two sets of extrusion limiting parts 16 changes until the distance between the two sets of extrusion limiting parts 16 is basically the same as the width of the pearl cotton to be cut in this batch. The pearl cotton is then placed between the two sets of extrusion limiting parts 16 for quick positioning. After placement, rotate the two sets of threaded rods 6 in the forward direction respectively. As mentioned above, the installation chamber 8 will drive the corresponding conveyor belt assembly 9 to move downward until the conveyor belt assembly 9 is in contact with the top of the pearl cotton, thus performing the initial stabilization task on the pearl cotton. Push the pearl cotton towards the U-shaped mounting bracket 2. During this process, the conveyor belt assembly 9 can perform corresponding conveying actions until the pearl cotton reaches the designated position. Control the electric push rod 4 to drive the cutting head 5 to move downward. At this time, the inclined part of the extrusion block 11 first extrudes the two sets of movable parts 15. As mentioned above, the movable parts 15 then drive the extrusion limiting part 16 to move to the position where it is in close contact with the corresponding conveyor belt assembly 9. This greatly increases the resistance of the conveying action of the conveyor belt assembly 9, preventing the pearl cotton from easily shifting. Then, the electric push rod 4 continues to drive the cutting head 5 to move downward to perform the cutting task. Throughout the entire cutting process, the extrusion block 11 always maintains the extrusion of the movable part 15. After the cutting is completed, the electric push rod 4 drives the cutting head 5 to move upward to the initial height. At this time, the extrusion block 11 does not extrude on the moving part 15. Under the elastic action of the spring 17, the moving part 15 drives the extrusion limiting part 16 to release the pressing and extrusion on the corresponding conveyor belt assembly 9, so that the operator can apply a suitable force to the pearl cotton to push the subsequent pearl cotton to continue to approach the U-shaped mounting frame 2, thereby facilitating the completion of continuous cutting tasks.

[0017] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
