Description

Technical Field

[0001] This utility model belongs to the technical field of wet spinning machines, and in particular relates to a protective device for wet spinning machines. Background Technology

[0002] Wet spinning technology utilizes a specific solvent to dissolve high-molecular polymers into a spinning solution, which is then extruded through a spinneret and placed into a coagulation bath (usually water or a chemical solution at varying temperatures) to rapidly solidify into primary fibers. These primary fibers then undergo a series of processes including washing, stretching, and drying to ultimately form fiber bundles. Protective covers on wet spinning machines are used to cover the moving parts of the machine, preventing operators from accidentally coming into contact with high-speed rotating components and avoiding accidental injury. During the spinning process, solvents or fibers may adhere to the protective cover. Because cleaning these covers in related technologies is inconvenient, they easily accumulate dirt, further affecting observation and the normal operation of the equipment. Furthermore, the cumbersome disassembly and assembly of these protective covers, especially when frequent maintenance or inspection is required, increases the workload of operators. Summary of the Invention

[0003] In view of this, the present invention aims to at least partially solve one of the related technical problems.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0005] A protective device for a wet spinning machine includes a fixed panel, a protective shell, a magnetic connection structure, an upper cover plate, a lower cover plate, a collection structure, a fixing structure, a heat dissipation structure, a filter structure, two flow guiding structures, and two guide structures.

[0006] The protective housing is hollow inside. The upper cover plate and the lower cover plate are symmetrically arranged on the upper and lower sides of the protective housing. The upper cover plate is integrally connected to the protective housing. The lower cover plate can cover the groove at the bottom of the protective housing. The upper cover plate is connected to the front end face of the fixed panel through the magnetic connection structure. The lower cover plate is connected to the front end face of the fixed panel through the fixing structure.

[0007] One end of the protective housing is slidably engaged with the fixed panel through two guide structures, and the other end of the protective housing is provided with a heat dissipation structure. The filter structure is provided inside the heat dissipation structure and is fixedly connected to the inner wall of the protective housing.

[0008] Two flow guiding structures are symmetrically arranged on the inner wall of the protective shell, and the collection structure is arranged on the lower cover plate, with the bottoms of the two flow guiding structures facing the collection structure.

[0009] The upper and lower ends of the fixed panel are provided with bent edges for connection.

[0010] Furthermore, the guiding structure includes a guide groove and a guide slide plate. The guide slide plate is fixedly connected to the outer wall of the end of the protective housing, and the fixed panel slides in cooperation with the guide slide plate through the guide groove.

[0011] Furthermore, the heat dissipation structure includes multiple heat dissipation holes, which are evenly distributed at the ends of the protective housing.

[0012] Furthermore, the magnetic connection structure includes a first fixing plate, a connecting plate, a bar magnet, and a plurality of first fixing bolts. The first fixing plate is connected to the fixing panel through the plurality of first fixing bolts. The bar magnet is connected to the first fixing plate. The connecting plate is disposed on the upper end surface of the upper cover plate. The connecting plate is made of magnetically conductive material. The connecting plate and the bar magnet are detachably connected.

[0013] Furthermore, the fixing structure includes a second fixing plate and a plurality of second fixing bolts. The second fixing plate is disposed on the lower end face of the lower cover plate and is detachably connected to the fixing panel by the plurality of second fixing bolts. The second fixing plate is used to support the lower cover plate.

[0014] Furthermore, the flow guiding structure is an angled flow guiding plate, which is integrally connected to the inner wall of the protective housing.

[0015] Furthermore, the collection structure includes a collection trough and multiple reinforcing ribs. The collection trough is located in the middle of the lower cover plate, and the multiple reinforcing ribs are symmetrically arranged outside the collection trough at the position where they connect with the lower cover plate.

[0016] Compared with the prior art, the protective device for wet spinning machines described in this utility model has the following advantages:

[0017] 1. The flow guiding structure is an angled guide plate, integrally connected to the inner wall of the protective housing. The angled guide plate design effectively guides the spinning solution or residue along a predetermined path, preventing the liquid from spreading randomly inside the equipment. The collection structure includes a collection tank and multiple ribs, effectively collecting the waste liquid guided by the guide plate and preventing spillage or scattering. Centralized collection helps operators quickly clean up waste liquid during maintenance, reducing the complexity and time of cleaning work and improving maintenance efficiency.

[0018] 2. The magnetic connection structure, consisting of a bar magnet and a connecting plate, enables quick disassembly and installation without the need for additional tools, greatly simplifying the operation process. This is especially important in environments requiring frequent equipment maintenance and inspection. Magnetic connections avoid the wear and fatigue that can occur with traditional mechanical connections such as bolts and clips, extending the lifespan of the device components. The magnetic connection structure also features self-positioning; the protective cover automatically aligns when it approaches the fixed panel, ensuring accurate connection positioning and effectively reducing the time and difficulty of manual adjustments.
