Description

Technical Field

[0001] This utility model belongs to the field of metal mesh mat processing technology, specifically relating to a metal mesh mat debris screening device. Background Technology

[0002] Fine metal wires are woven into a mesh, cut to a specified length, and then stamped to create a soft, cushioning material. Due to its high-temperature resistance, it is widely used in the following areas: the outer perimeter of exhaust pipes in automotive exhaust recirculation systems, and engine heat shields (as anti-vibration gaskets). Metal mesh gaskets provide excellent heat resistance, shock absorption, and noise reduction.

[0003] Metal mesh mats generate debris during production. After production, a rotary screener is needed to screen the debris and finished product. The rotary screener is usually made of multiple welded rotary cages, each with screen holes of different sizes. Through the screen holes on different rotary cages, the metal mesh mats can be screened in multiple stages. During the operation of the rotary screener, the metal mesh mats will repeatedly rub against the inner wall of the rotary cage. After long-term use, multiple rotary cages will experience varying degrees of wear. When a rotary cage is damaged, it cannot be disassembled and replaced individually, which leads to many inconveniences in the later maintenance of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a metal mesh mat debris screening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a metal mesh mat debris screening device, comprising a rotating cage and a collar, wherein there are multiple rotating cages, and adjacent rotating cages are fixedly installed together by collars, and both ends of the rotating cage are integrally connected with connecting rings, and four annularly distributed connecting blocks are fixedly connected to the surface of the connecting rings, and the surface of the connecting blocks is provided with insertion holes. The collar is fitted between two adjacent connecting rings. The inner circumference of the connecting ring is provided with a connecting groove that matches the connecting block. The collar has an annular cavity inside. Multiple annularly distributed screws are rotatably installed inside the annular cavity. A movable rod is threaded onto the screw. Two spaced-apart plug rods are fixedly connected to one side of the movable rod.

[0006] In a preferred embodiment, the rotating cage has a plurality of sieve holes on its circumferential surface.

[0007] In a preferred embodiment, the aperture of the sieve holes on the plurality of rotating drums increases sequentially.

[0008] In a preferred embodiment, a nut is fixedly connected to one end of the screw.

[0009] In a preferred embodiment, the outer circumference of the collar is provided with a plurality of annularly distributed grooves, and the nut is embedded in the grooves.

[0010] In a preferred embodiment, a limiting rod is fixedly connected to both sides of each screw inside the annular cavity, and the two ends of the movable rod are slidably sleeved on the limiting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This metal mesh mat debris screening device, through the setting of collars, allows multiple rotating cages to be freely disassembled and assembled. When a rotating cage is damaged, it can be disassembled and replaced individually, avoiding many inconveniences in the later maintenance of the equipment. This metal mesh mat debris screening device, through the arrangement of connecting rings, connecting blocks, insertion holes, connecting grooves, annular cavities, screws, movable rods, insertion rods, and nuts, allows for easy connection of rotating cages. Simply place the collar onto the connecting ring of the adjacent rotating cage, insert the connecting block into the corresponding connecting groove, and then rotate the nut. This causes the nut to rotate the screw, which in turn causes the movable rod to slide along the limiting rod. The movable rod then drives the insertion rod to insert into the insertion hole, thus securing the connecting rings of the adjacent rotating cages. This facilitates the assembly and disassembly of the rotating cages. Attached Figure Description

[0014] The present invention will be further described below with reference to the embodiments.

[0015] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0016] Please see Figure 1-3This utility model provides a metal mesh mat debris screening device, including a rotating cage 1 and a collar 2. There are multiple rotating cages 1, and a number of screen holes 14 are opened on the circumference of the rotating cage 1. The diameter of the screen holes 14 on the multiple rotating cages 1 increases sequentially. Adjacent rotating cages 1 are fixedly installed together by the collar 2. The collar 2 allows the multiple rotating cages 1 to be freely disassembled and assembled. When a rotating cage 1 is damaged, it can be disassembled and replaced individually, avoiding many inconveniences in the later maintenance of the equipment.

[0017] Specifically, both ends of the rotating cage 1 are integrally connected with connecting rings 11. Four annularly distributed connecting blocks 12 are fixedly connected to the surface of the connecting rings 11. The surface of the connecting blocks 12 is provided with insertion holes 13. A collar 2 is sleeved between two adjacent connecting rings 11. The inner circumference of the connecting ring 11 is provided with connecting grooves 21 that are adapted to the connecting blocks 12. An annular cavity 22 is provided inside the collar 2. Multiple annularly distributed screws 23 are rotatably installed inside the annular cavity 22. A movable rod 24 is threaded onto the screw 23. Two spaced-apart insertion rods 25 are fixedly connected to one side of the movable rod 24. A nut 26 is fixedly connected to one end of the screw 23. The annular cavity 22 is fixedly connected to both sides of each screw 23. With a limiting rod 28, the two ends of the movable rod 24 are slidably sleeved on the limiting rod 28. Through the arrangement of the connecting ring 11, connecting block 12, insertion hole 13, connecting groove 21, annular cavity 22, screw 23, movable rod 24, insertion rod 25 and nut 26, when connecting the rotating cage 1, simply put the collar 2 on the connecting ring 11 of the adjacent rotating cage 1 and insert the connecting block 12 into the corresponding connecting groove 21. Then, the nut 26 can be rotated, so that the nut 26 drives the screw 23 to rotate, so that the screw 23 drives the movable rod 24 to slide along the limiting rod 28, so that the movable rod 24 drives the insertion rod 25 to be inserted into the insertion hole 13, and the connecting ring 11 of the adjacent rotating cage 1 is inserted and fixed, thus facilitating the assembly and disassembly of the rotating cage 1.

[0018] The collar 2 has multiple annularly distributed grooves 27 on its outer circumference. The nut 26 is embedded in the grooves 27. The grooves 27 can be used to store and protect the nut 26, preventing it from being exposed to the outside and being hit.

[0019] The working principle and usage process of this utility model are as follows: First, when connecting the rotating cage 1, simply put the collar 2 on the connecting ring 11 of the adjacent rotating cage 1 and insert the connecting block 12 into the corresponding connecting groove 21. Then, rotate the nut 26 to drive the screw 23 to rotate, and the screw 23 will drive the movable rod 24 to slide along the limiting rod 28. The movable rod 24 will drive the insertion rod 25 to be inserted into the insertion hole 13, thereby connecting and fixing the connecting ring 11 of the adjacent rotating cage 1. This facilitates the assembly and disassembly of the rotating cage 1, allowing multiple rotating cages 1 to be freely assembled and disassembled. When a rotating cage 1 is damaged, it can be disassembled and replaced individually, avoiding many inconveniences during later equipment maintenance.
