It is mainly used for air filtration and dust removal, collecting dust particles to purify the air and protect the environment, in industries such as smelting, chemical plants, sugar refining, dyeing, pharmaceuticals, and food processing.

[0003] During filter cloth production, holes are made in the filter cloth to facilitate its fixation, taking into account the installation needs between the filter cloth and the equipment. For example, the utility model patent with publication number CN222553765U, entitled "A Filter Cloth Hole Opener", discloses that the filter cloth includes a cutting cylinder with a cutting opening at the bottom and a handle fixedly connected to the top of the cutting cylinder. The top of the handle is provided with a heat insulation sleeve. A resistance wire coil is provided on the inner wall of the cutting cylinder, and the resistance wire coil is located in the middle of the cutting cylinder. The resistance wire coil is electrically connected to a power line, and the power line is fixedly wound on the handle.

[0004] When using the aforementioned hot-cutting perforation device, after opening the filter cloth, the molten waste material from the opening process can easily remain and stick inside the device. People usually try to remove the waste material by hand, but the device itself is very hot, and removing it by hand can easily cause burns, posing a safety hazard. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a filter cloth perforation device to solve the technical problem that molten waste material adheres to the device and is difficult to remove during the use of existing filter cloth thermal perforation devices.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A filter cloth perforation device includes a worktable for placing filter cloth, a mounting frame fixedly mounted on the worktable, a mounting plate slidably mounted on the mounting frame, an electric heating ring knife for perforating the filter cloth on the worktable at the bottom of the mounting plate, an ejector for ejecting waste material from the electric heating ring knife slidably mounted on the mounting plate, and a driving member for driving the mounting plate to slide and driving the ejector during the sliding of the mounting plate.

Guide block. Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Example:

[0022] Reference Figures 1-4 As shown, a filter cloth perforation device includes a worktable 1 for placing the filter cloth. A mounting frame 2 is fixedly mounted on the worktable 1. A mounting plate 3 is vertically slidable on the mounting frame 2. A mounting block 5 is fixedly mounted on the mounting plate 3. A guide groove 20 with both ends passing through is vertically opened on the side wall of the mounting block 5. A guide block 21 is fixedly mounted on the mounting frame 2, and the guide block 21 slides into the guide groove 20. The cooperation of the guide groove 20 and the guide block 21 ensures that the mounting block 5 slides vertically on the mounting frame 2. The bottom of the mounting plate 3 is provided with an electric heating ring knife 4 for perforating the filter cloth on the worktable 1. The electric heating ring knife 4 is a common existing technology in this field, and its structure will not be described in detail here. The cutting edge of the electric heating ring knife 4 can be ring-shaped or other shapes depending on the process, adapting to the processing technology. The mounting plate 3 is provided with a plurality of guide rods 15, which are vertically slidably inserted through the mounting frame 2. Each of the guide rods 15 is fitted with a second spring 16, and the two ends of the second spring 16 are respectively fixed to the corresponding guide rod 15 and the mounting frame 2. The arrangement of the guide rods 15 and the second spring 16 enables the electric heating ring knife 4 to retract vertically stably after making holes in the filter cloth.

[0023] like Figure 1 , Figure 2As shown, the mounting plate 3 is vertically slidable and equipped with an ejector for ejecting waste material from the electric heating ring knife 4. The mounting frame 2 contains a driving component for driving the mounting plate 3 to slide and for driving the ejector during the sliding process. The driving component includes a driving rod 6, a cam 7, and a connecting rod 8. The driving rod 6 is rotatably mounted on the mounting frame 2, the cam 7 is fixed to the driving rod 6, one end of the connecting rod 8 is hinged to the side wall of the cam 7 away from the driving rod 6, and the other end of the connecting rod 8 is hinged to the mounting block 5. The connecting rod 8 can be hinged to the cam 7 or the mounting block 5 via a rotating shaft or bearing. An external motor drives the driving rod 6 to rotate, which in turn drives the cam 7 to rotate. When the cam 7 rotates, the connecting rod 8 causes the mounting block 5 to rise and fall on the mounting frame 2, further driving the mounting plate 3 and the electric heating ring knife 4 to rise and fall.

[0024] like Figure 2 , Figure 3 and Figure 4 As shown, the ejector includes an ejector rod 9, a roller 10, and an ejector pin 11. A countersunk hole 12 is vertically formed at the axis of the mounting block 5. The ejector rod 9 slides through the countersunk hole 12. The roller 10 is rotatably mounted on the ejector rod 9 and rolls against the outer circle of the cam 7. The mounting plate 3 has a clearance hole 13 that connects the countersunk hole 12 and the electric heating ring knife 4. The ejector pin 11 is fixed to the end of the ejector rod 9 away from the cam 7. The ejector pin 11 is electrically... When the heating ring knife 4 rises, it extends into the electric heating ring knife 4 through the clearance hole 13. The countersunk hole 12 is provided with a first spring 14, which is sleeved on the ejector rod 9. Specifically, when the electric heating ring knife 4 rises, the ejector pin 11 descends, and vice versa. This can prevent the ejector pin 11 from interfering when the electric heating ring knife 4 is opening. The first spring 14 can cause the mounting block 5 to slide downward, which in turn drives the ejector rod 9 and the ejector pin 11 upward.

[0025] like Figure 2 As shown, an iron placement plate 17 is fixed on the workbench 1. A cross groove 18 for positioning is opened on the placement plate 17 and located directly below the electric heating ring knife 4. Several magnets 19 for fixing the filter cloth are provided on the placement plate 17.

[0026] Working principle:

[0027] When the device is started, the filter cloth is laid flat on the placement plate 17 of the workbench 1, and the position to be drilled is aligned with the cross groove 18, and then fixed by several magnets 19 set on the plate. An external motor drives the drive rod 6 to rotate, which drives the cam 7 fixed on it to rotate synchronously. When the cam 7 rotates, it pulls or pushes the mounting block 5 through the connecting rod 8 hinged to its side wall. The guide groove 20 opened on the side wall of the mounting block 5 slides and engages with the guide block 21 fixed on the mounting frame 2, constraining the mounting block 5 to slide strictly vertically along the mounting frame 2. When the mounting plate 3 moves downward, it drives the bottom electric heating ring knife 4 to perform thermal melting cut on the filter cloth below, completing the drilling. During this process, several guide rods 15 on the mounting plate 3 slide in the mounting frame 2 and compress the second spring 16 on them.

[0028] As the cam 7 continues to rotate to the stage where the mounting plate 3 rises, the compressed second spring 16 releases its energy, assisting in pushing the guide rod 15 and the mounting plate 3 to retract smoothly and quickly upwards, causing the electric heating ring knife 4 to detach from the filter cloth and the worktable 1. At the same time, the roller 10 fixed on the ejector rod 9 rolls against the outer circle of the rotating cam 7. When the cam 7 rotates to the protruding profile of the cam 7, it will push the ejector rod 9 downwards. The ejector rod 9 slides downwards along the countersunk hole 12 at the axis of the mounting block 5, driving the ejector pin 11 fixed at its lower end to pass through the clearance hole 13 on the mounting plate 3 and extend downwards into the interior of the rising electric heating ring knife 4, pushing out the filter cloth waste remaining in the knife cavity after cutting, so that it detaches from the ring knife.

[0029] As the cam 7 continues to rotate, the first spring 14 inside the countersunk hole 12 pushes the ejector rod 9 upward to reset, and the ejector pin 11 retracts to avoid interference when the electric heating ring knife 4 is pressed down next time. The mounting plate 3 is reset under the constraint of the connecting rod 8, the guide rod 15, and the second spring 16, preparing for the next drilling cycle.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
