Abstract
Description
Technical Field
[0001] This utility model relates to the field of skip-cutting die technology, specifically a skip-cutting die for a deformation-resistant separation membrane material. Background Technology
[0002] A separation membrane is a membrane material with selective permeation capability. It is generally classified according to its separation mechanism and application range into microfiltration membranes, ultrafiltration membranes, nanofiltration membranes, reverse osmosis membranes, pervaporation membranes, ion exchange membranes, etc. A separation membrane is an interface that can confine and transfer fluid substances in a specific way, separating two phases or two parts. The membrane can be solid or liquid. The fluid substances separated by the membrane can be liquid or gaseous. Existing separation membranes are manufactured with a fixed width; therefore, sometimes a slitting device is needed to cut the separation membrane into two parts of a specific width.
[0003] A search revealed that Chinese patent CN219190385U discloses a die-cutting structure for an ultrathin separation membrane material, comprising a base plate, a support plate fixedly connected to the upper surface of the base plate, a top plate fixedly connected to the right side of the support plate, a hydraulic cylinder fixedly mounted on the upper surface of the top plate, a die-cutting blade fixedly connected to the output end of the hydraulic cylinder, a die-cutting plate fixedly connected to the upper surface of the base plate, a bottom box connected to the lower surface of the base plate, a stroke groove formed on the left side of the bottom box, a sliding plate inserted inside the stroke groove, a connecting block fixedly connected to the upper surface of the sliding plate, a sealing push plate fixedly connected to the upper surface of the connecting block, a lifting plate fixedly connected to the left side of the sliding plate, a fixing plate fixedly connected to the lower surface of the base plate, a pull rod movably inserted into the outer surface of the fixing plate, and a limit plate fixedly connected to the right end of the pull rod. This series of structural designs facilitates the fixing of the separation membrane.
[0004] The above-mentioned utility model has the following problems:
[0005] 1. Existing die-cutting molds are made in advance according to the actual needs of the separation membrane when cutting it. One die-cutting mold can only cut separation membranes of one width. If you want to cut separation membranes of different widths, you need to make a new die-cutting mold. The adaptability is poor. Moreover, the die-cutting mold cannot be buffered when punching the separation membrane. During the long-term punching process, the die-cutting mold is easily damaged, which reduces the service life of the die-cutting mold.
[0006] Therefore, those skilled in the art have provided a deformation-resistant separation membrane material skip-cutting die to solve the problems mentioned in the background art. Utility Model Content
[0007] The purpose of this invention is to provide a deformation-resistant separation membrane material skip-cutting die to solve the problems mentioned in the background art.
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A deformation-resistant separation membrane material skip-cutting die includes a mounting base. A damping spring is fixedly connected to the inner wall of the mounting base. A fixing member is fixedly connected to the top of the damping spring. A movable groove is opened on the inner wall of the fixing member. A bidirectional lead screw is rotatably connected to the inner wall of the movable groove. Both ends of the bidirectional lead screw are threaded with lead screw sleeves. A movable block is fixedly connected to the surface of the lead screw sleeve. The movable block is slidably connected to the movable groove. A cutter is fixedly connected to the upper surface of the movable block.
[0010] As a further embodiment of this utility model: the fixing member has a transmission cavity inside, and one end of the bidirectional lead screw extends into the transmission cavity, and one end of the bidirectional lead screw is fixedly connected to a first bevel gear.
[0011] As a further embodiment of this utility model: a transmission rod is rotatably connected to the inner side wall of the transmission cavity, and a second bevel gear is fixedly connected to one end of the transmission rod, and the second bevel gear meshes with the first bevel gear.
[0012] As a further improvement of this utility model: a knob is rotatably connected to the surface of the fixing member, and the knob shaft end is fixedly connected to one end of the transmission rod.
[0013] As a further embodiment of this utility model: a grooved plate is fixedly connected to the lower surface of the fixing member, a sliding groove is provided on the inner side wall of the grooved plate, and a slider is slidably connected to the inner side wall of the sliding groove.
[0014] As a further improvement of this utility model: a return spring is fixedly connected between the slider and the inner wall of the groove, and a rotating shaft is rotatably connected to the surface of the slider.
[0015] As a further improvement of this utility model: a connecting rod is fixedly connected to one end of the rotating shaft, and one end of the connecting rod is rotatably connected to the side wall of the damping spring.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. When adjusting the distance between the two cutters, the transmission rod can be rotated by turning the knob. The rotation of the transmission rod drives the second bevel gear to rotate, which in turn drives the first bevel gear to rotate. The rotation of the first bevel gear drives the double-acting lead screw to rotate, which in turn drives the lead screw sleeve to move. The movement of the lead screw sleeve drives the movable block to move, which in turn drives the cutter to move. This allows the two cutters to move in opposite directions, thus adjusting the distance between them. This adjustment can be made according to the actual needs of the separation membrane, making it highly adaptable. It eliminates the need to remake the die mold, saving resources.
[0018] 2. The combination of damping springs, slotted plates, sliders, return springs, and connecting rods provides support for the fixed components, thus acting as a shock absorber for the overall structure. The impact of the cutter during cutting is transmitted to the damping springs, causing the internal springs to undergo elastic deformation, absorbing some energy and generating a reaction force. At the same time, the internal damper dissipates energy through friction and fluid resistance, reducing the energy of the vibration system. Combined with elastic deformation and energy dissipation, the damping springs can effectively reduce the vibration amplitude of the structure, reduce the impact on the overall structure, effectively reduce the damage caused by impacts, provide shock protection, ensure the overall stability of the structure, and extend the service life of the cutter.

[0024] 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.
[0025] Example 1
[0026] Reference Figure 1-4This embodiment provides a deformation-resistant separation membrane material skip-cutting die 8, including a mounting base 1. A damping spring 2 is fixedly connected to the inner wall of the mounting base 1. A fixing member 3 is fixedly connected to the top of the damping spring 2. A movable groove 4 is opened on the inner wall of the fixing member 3. A bidirectional lead screw 5 is rotatably connected to the inner wall of the movable groove 4. Both ends of the bidirectional lead screw 5 are threadedly connected to lead screw sleeves 6. A movable block 7 is fixedly connected to the surface of the lead screw sleeve 6. The movable block 7 is slidably connected to the movable groove 4. A cutter 8 is fixedly connected to the upper surface of the movable block 7. A transmission cavity 9 is opened inside the fixing member 3, and one end of the bidirectional lead screw 5 extends into the transmission cavity 9. A first bevel gear 10 is fixedly connected to one end of the bidirectional lead screw 5. A transmission rod 11 is rotatably connected to the inner wall of the transmission cavity 9. A second bevel gear 12 is fixedly connected to one end of the transmission rod 11. Gear 12 meshes with the first bevel gear 10. A knob 13 is rotatably connected to the surface of the fixing part 3. The shaft end of the knob 13 is fixedly connected to one end of the transmission rod 11. When adjusting the distance between the two cutters 8, the transmission rod 11 can be rotated by rotating the knob 13. The rotation of the transmission rod 11 drives the second bevel gear 12 to rotate, which in turn drives the first bevel gear 10 to rotate. The rotation of the first bevel gear 10 drives the bidirectional lead screw 5 to rotate, which in turn drives the lead screw sleeve 6 to move. The movement of the lead screw sleeve 6 drives the movable block 7 to move, which in turn drives the cutter 8 to move. This allows the two cutters 8 to move towards or away from each other, thereby adjusting the distance between them. This adjustment can be made according to the actual needs of the separation membrane, making it highly adaptable. It eliminates the need to remake the die mold, saving resources.
[0027] Example 2
[0028] Reference Figure 1-2 This embodiment is based on the previous embodiment, but differs in that a groove plate 14 is fixedly connected to the lower surface of the fixing member 3. A sliding groove 15 is formed on the inner side wall of the groove plate 14. A slider 16 is slidably connected to the inner side wall of the sliding groove 15. A return spring 17 is fixedly connected between the slider 16 and the inner side wall of the sliding groove 15. A rotating shaft 19 is rotatably connected to the surface of the slider 16. A connecting rod 18 is fixedly connected to one end of the rotating shaft 19, and one end of the connecting rod 18 is rotatably connected to the side wall of the damping spring 2. The combination of the damping spring 2, the groove plate 14, the slider 16, the return spring 17, and the connecting rod 18 provides support for the fixing member 3. The damping spring 2 acts as a shock absorber for the overall structure. When the cutter 8 punches, the impact is transmitted to the damping spring 2, causing the spring inside the damping spring 2 to undergo elastic deformation, absorbing some energy and generating a reaction force. At the same time, the internal damper dissipates energy through friction and fluid resistance, reducing the energy of the vibration system. Combined with elastic deformation and energy dissipation, the damping spring 2 can effectively reduce the vibration amplitude of the structure and reduce the impact on the overall structure. Under the action of the damping spring 2, the damage caused by the impact can be effectively reduced, providing impact protection, ensuring the overall stability of the structure, and ensuring the service life of the cutter 8.
