Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically a meltblown filter element slitting machine. Background Technology

[0002] Meltblown filter elements are tubular filter elements made from non-toxic and odorless polypropylene particles through heating, melting, spinning, drawing, and receiving. During the manufacturing process, large filter rods are first made, and then the long filter elements are cut into filter elements of different lengths. Therefore, a cutting device is required. A Chinese utility model patent (publication number: CN222290284U) discloses a cutting device for processing oil filter elements, which can cut filter elements of different sizes, making the cutting device more versatile.

[0003] However, the above-mentioned device still has some shortcomings in use. Specifically, in the prior art, each placement rack is equipped with two electric push rods. The prior art can simultaneously meet the positioning and processing of multiple filter elements. Therefore, the use of a large number of electric push rods, although it can meet the positioning needs, also increases the cost of use and the subsequent maintenance costs. Therefore, in view of the above situation, a meltblown filter element slitting machine is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a meltblown filter element slitting machine. Through the structural design of the first perforation, the second perforation, the cylinder, the sleeve rod, and the connecting rod, the positioning effect is guaranteed while reducing the number of cylinders used, thereby reducing the cost of use and subsequent maintenance. This solves the problem that the use of a large number of electric push rods increases the cost of use and subsequent maintenance.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a meltblown filter element slitting machine, comprising a worktable and a cutting assembly. A movable positioning assembly is provided on the worktable, comprising three U-shaped plates. A partition is fixed to each U-shaped plate, and a right clamping plate slides on the partition. A connecting plate is fixed to the bottom of the right clamping plate. A sleeve rod is rotatably connected to one side of the connecting plate. One end of the sleeve rod passes through the U-shaped plate and is threadedly engaged with a connecting rod. One end of the connecting rod is fixedly connected to the connecting plate on the right U-shaped plate. A cylinder is fixed to the right U-shaped plate, and the moving end of the cylinder is fixed to the right connecting plate. Another connecting rod is fixed to the other side of the connecting plate, and the connecting rod passes through the U-shaped plate and rotates on the connecting plate on the left U-shaped plate.

[0007] Furthermore, a mounting bracket is fixed to the top of the workbench, and the cutting components are mounted on the mounting bracket.

[0008] Furthermore, the partition has a rectangular groove, the connecting plate slides into the rectangular groove, and the left clamp is fixed to the end of the partition away from the right clamp. The opposite surfaces of the left and right clamps are both arc-shaped.

[0009] Furthermore, a first through hole and a second through hole are respectively provided on the two side plates of the U-shaped plate. The second through hole is in clearance fit with the sleeve rod, and the first through hole is in clearance fit with the connecting rod.

[0010] Furthermore, the sleeve rod has a threaded groove, and the connecting rod has a threaded end, which is threadedly engaged with the threaded groove.

[0011] Furthermore, the worktable has three moving slots, each with a moving component and a positioning component. There are two sets of positioning components, which are respectively located at both ends of the moving component.

[0012] The moving component includes a bidirectional screw that rotates on the middle moving slot. One end of the bidirectional screw passes through the moving slot and is connected to an external drive source. Guide rods are horizontally fixed on the other two moving slots.

[0013] Furthermore, a drive block is fixed to the bottom of the central U-shaped plate, and guide blocks are fixed to the bottom of the left and right U-shaped plates. The guide blocks have round holes that are clearance-fitted with the guide rods. Both drive blocks have screw holes with opposite thread directions that are threaded into the bidirectional screw.

[0014] This utility model has the following beneficial effects:

[0015] This utility model, through its structural design of a first perforation, a second perforation, a cylinder, a sleeve rod, and a connecting rod, allows for the synchronous positioning of multiple meltblown filter rods after they are placed in place, using a single cylinder to ensure positioning effectiveness while reducing the number of cylinders required and lowering the cost of use and subsequent maintenance.

[0016] This invention, through the structural design of the sleeve rod, threaded groove, and connecting rod, can locally change the distance between the right and left clamping plates on a single U-shaped plate, thereby enabling the device to simultaneously meet the positioning requirements of filter rods of different specifications and improving the versatility of the device.

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a meltblown filter element slitting machine, including a workbench 1 and a cutting component 3. The top of the workbench 1 is fixed with a mounting frame 2, and the cutting component 3 is provided on the mounting frame 2.

[0025] The cutting component 3 has the same structure as the existing technology. The electric push rod can be moved by the electric lead screw module, thereby changing the position of the cutting machine connected to the moving end of the electric push rod, and cutting multiple filter rods. The cutting machine uses a high-speed rotating circular blade. The blade is made of high-quality cemented carbide, which has a sharp cutting edge and good wear resistance, and can cut the filter rods quickly and accurately.

[0026] The workbench 1 is provided with a movable positioning component 5, which includes three U-shaped plates 50. A partition 51 is fixed on the U-shaped plate 50, and a right clamping plate 53 slides on the partition 51. A connecting plate 54 is fixed at the bottom of the right clamping plate 53.

[0027] The partition 51 has a rectangular groove, and the connecting plate 54 slides in the rectangular groove. The left clamping plate 52 is fixed to the end of the partition 51 away from the right clamping plate 53. The opposite surfaces of the left clamping plate 52 and the right clamping plate 53 are both arc-shaped. The arc-shaped surfaces are wrapped with rubber material. The rubber material has good elasticity and friction, which can provide sufficient clamping force when clamping the filter rod, while avoiding damage to the surface of the meltblown filter rod.

[0028] A sleeve rod 6 is rotatably connected to one side of the connecting plate 54 via a bearing. One end of the sleeve rod 6 passes through the U-shaped plate 50 and is threadedly fitted with a connecting rod 7. One end of the connecting rod 7 is fixedly connected to the connecting plate 54 on the right U-shaped plate 50. A cylinder 59 is fixed on the right U-shaped plate 50, and the moving end of the cylinder 59 is fixed on the right connecting plate 54.

[0029] Another connecting rod 7 is fixed on the other side of the connecting plate 54. The connecting rod 7 passes through the U-shaped plate 50 and rotates on the connecting plate 54 on the left U-shaped plate 50.

[0030] The workbench 1 has three moving slots 10, each with a moving component 4. The moving component 4 has two sets of positioning components 5, which are respectively located at both ends of the moving component 4.

[0031] The moving component 4 includes a bidirectional screw 40 that rotates on the intermediate moving slot 10. One end of the bidirectional screw 40 passes through the moving slot 10 and is connected to an external drive source. The drive source can be a servo motor. A through hole is provided on the worktable 1. The bidirectional screw 40 passes through the through hole and is fixedly connected to the output end of the servo motor through a coupling. Guide rods 41 are horizontally fixed on the other two moving slots 10.

[0032] A drive block 57 is fixed to the bottom of the central U-shaped plate 50, and guide blocks 58 are fixed to the bottom of the left and right U-shaped plates 50. The guide blocks 58 have round holes that are clearance-fitted with the guide rod 41. Both drive blocks 57 have screw holes with opposite thread directions that are threaded to the bidirectional screw rod 40.

[0033] The two side plates of the U-shaped plate 50 are respectively provided with a first through hole 55 and a second through hole 56. The second through hole 56 is in clearance fit with the sleeve rod 6, and the first through hole 55 is in clearance fit with the connecting rod 7. The sleeve rod 6 is provided with a threaded groove 60, and the connecting rod 7 is provided with a threaded end, which is threadedly engaged with the threaded groove 60.

[0034] When the drive source is started, it drives the bidirectional screw 40 to rotate. Since the screw holes on the two drive blocks 57 have opposite thread directions and are threadedly engaged with the bidirectional screw 40, the rotation of the bidirectional screw 40 will cause the two drive blocks 57 to move towards or away from each other. Under the limit of the guide rod 41, the two sets of positioning components 5 move towards or away from each other synchronously, so as to meet the positioning requirements of filter rods of different lengths.

[0035] When the filter rod needs to be positioned and clamped, the cylinder 59 is activated, and its moving end extends, pushing the right connecting plate 54 to move to the left along the rectangular groove on the partition 51. Since the right connecting plate 54 is fixedly connected to the connecting rod 7, and the connecting rod 7 is threadedly engaged with the sleeve rod 6, the movement of the right connecting plate 54 will drive the sleeve rod 6 to move horizontally, pushing the middle connecting plate 54 to move synchronously. Similarly, the movement of the middle connecting plate 54 will cause the left connecting plate 54 to move to the left along the rectangular groove on the partition 51. In this way, the left clamping plate 52 and the right clamping plate 53 will move towards the middle at the same time, clamping the filter rod between them, ensuring that the filter rod will not shake during the cutting process. When it is necessary to adjust the moving distance of the connecting plates 54 at different positions, the sleeve rod 6 is rotated to drive the connecting plates 54 at different positions to change their initial positions, thereby meeting the processing needs of filter rods of different sizes.

[0036] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
