Description

Technical Field

[0001] This utility model belongs to the field of refined cotton production technology, and in particular relates to a dust recovery device for refined cotton production. Background Technology

[0002] According to the published patent CN120505736A, a refined cotton opening and dust collection device includes a mounting plate, which is symmetrically arranged at the bottom. The inner side wall of the mounting plate is fixedly connected to a track. An irregular gear is driven to rotate by a motor. When the meshing surface of the irregular gear contacts the convex tooth, it will drive the sliding plate to move horizontally. When the sliding plate moves, it will drive the dust collection device to move through the connecting rod. Then, the electromagnet will drive the magnetic block to move the sliding plate horizontally to the other side, thereby improving the dust collection range when the dust collection device is working. However, the following shortcomings still exist. The aforementioned equipment relies solely on gravity to install the sliding plate and filter plate, resulting in poor sealing. This can lead to gaps due to improper installation, causing some dust to leak through these gaps during dust collection, which severely affects the filtration effect. It is also difficult to ensure that the installation position is correct. Therefore, we propose a dust recovery device for refined cotton production. Utility Model Content

[0003] The purpose of this utility model is to provide a dust recovery device for refined cotton production. Through the installation mechanism and reciprocating mechanism, it solves the problem that simply relying on gravity to install the sliding plate and filter plate results in poor sealing, which may lead to excessive gaps due to improper installation. During dust collection, some dust may leak through the gaps, thus seriously affecting the filtration effect and making it difficult to ensure that the installation position is correct.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a dust recovery device for refined cotton production, including a ventilation box. The inner wall of the ventilation box is provided with an installation groove, the outer wall of the ventilation box is fixedly connected to the installation groove, the outer wall of the ventilation box is fixedly connected to a connecting pipe, the inner wall of the ventilation box is fixedly connected to a fan frame, the inner wall of the fan frame is fixedly connected to a fan, and the inner wall of the installation groove is provided with an installation mechanism. The installation mechanism includes a collection frame, the outer wall of which is slidably connected to the inner wall of the installation groove. A filter screen is fixedly connected to the inner wall of the collection frame. A handle is fixedly connected to the top outer wall of the collection frame. Several insertion rods are fixedly connected to the outer wall of the collection frame. The inner wall of each insertion rod has a slot. Several insertion rod seats are fixedly connected to the outer wall of the ventilation box. Each insertion rod seat has a slot on its inner wall. The inner wall of each slot is slidably connected to the outer wall of the insertion rod. A top rod is slidably connected to the inner wall of the insertion rod seat. A spring is fixedly connected to the outer wall of the top rod. The bottom outer wall of the spring is fixedly connected to the inner wall of the slot. A locking pin is slidably connected to the inner wall of the slot. A second locking groove is formed on the inner wall of the insertion rod seat. The inner wall of the second locking groove is slidably connected to the outer wall of the locking pin.

[0005] Furthermore, the outer wall of the ventilation box is provided with a reciprocating mechanism, which includes a motor frame. The outer wall of the motor frame is fixedly connected to the outer wall of the ventilation box, and a motor is fixedly connected to the inner wall of the motor frame.

[0006] Furthermore, the bottom output shaft of the motor is fixedly connected to a transmission rod via a coupling, and a convex shaft disc is fixedly connected to the bottom outer wall of the transmission rod.

[0007] Furthermore, a swing rod is rotatably connected to the top outer wall of the ventilation box, and a sliding groove is provided on the inner wall of the swing rod. The inner wall of the sliding groove is slidably connected to the outer wall of the convex shaft disk.

[0008] Furthermore, the inner wall of the swing rod is provided with a second sliding groove, and the outer wall of the ventilation box is fixedly connected with several connecting frames, and the inner walls of the several connecting frames are fixedly connected with several sliding rods.

[0009] Furthermore, a displacement plate is slidably connected to the outer wall of several of the sliding rods, and a convex shaft is fixedly connected to the outer wall of the displacement plate.

[0010] Furthermore, the outer wall of the convex shaft is slidably connected to the inner wall of the second slide groove, and a dust suction pipe is fixedly connected to the inner wall of the displacement plate.

[0011] Furthermore, a corrugated hose is fixedly connected to the outer wall of the suction pipe, and the outer wall of the corrugated hose is fixedly connected to the outer wall of the ventilation box.

[0012] This utility model has the following beneficial effects: 1. This utility model features a locking pin. If the filter screen needs to be removed from the mounting slot for separate cleaning, the fan can be turned off. Some excess dust will fall into the collection frame under gravity. By rotating the locking pin 90 degrees and pulling it out from the slot, several insert rods are no longer restricted by the locking pin. The spring will drive the top rod to move upward. During the movement, the top rod will push the insert rods out of the slots. Several insert rods will drive the collection frame to move upward a certain distance from the mounting slot. This allows for sufficiently precise installation and disassembly of the collection frame and filter screen, ensuring proper installation and avoiding gaps caused by improper installation that could lead to dust leakage. The operation is simple and reliable.

[0013] 2. This utility model incorporates a displacement plate. The motor drives the transmission rod to rotate, which in turn drives the cam disc to rotate. The cam disc then drives the swing rod to swing back and forth, which in turn drives the cam rod to move back and forth. The cam rod then drives the displacement plate to move left and right, which in turn causes the suction pipe to move left and right. This allows the suction pipe to move left and right during suction, effectively expanding the suction range and significantly improving the equipment's suction efficiency.
