Description

Technical Field

[0001] The utility model relates to the technical field of protective devices for extrusion molding machines, in particular to a protective device for extrusion molding machines. Background Art

[0002] The extruder is a plastic machine. Its main working principle is to rely on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the materials, and then form them through the die. In the process of producing magnetic strips, the extruder uses plastic adhesive and appropriate auxiliary agents to mix with magnetic powder to obtain the material. It is widely used in the field of refrigerator door seals and magnetic strips. It can also be used in disinfection cabinets, water dispensers, display cabinets, etc. to play a sealing and insurance role.

[0003] In the current magnetic strip production process, the magnetic strip needs to be water-cooled so that the molten magnetic strip can be quickly cooled and solidified to maintain its shape and magnetism. However, the existing extrusion molding machine lacks a protective device for the magnetic strip. The magnetic strip is not dried in time when it is water-cooled, resulting in the magnetic strip being in a humid environment after being rolled up. For a long time, the surface may be rusted or corroded, thereby affecting its use effect. Therefore, a protective device for an extrusion molding machine is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a protective device for an extrusion molding machine to solve the problems raised by the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a protective device for an extrusion molding machine, comprising a base, an air outlet pipe and an upper mounting groove, wherein a lower mounting groove is fixedly mounted on the upper surface of one end of the base, a removable lower absorbent cotton is mounted on the inner side of the lower mounting groove, the upper mounting groove is arranged at the upper end of the lower mounting groove, and a removable upper absorbent cotton is mounted on the inner side of the upper mounting groove;

[0006] An internal thread block is integrally connected to one side of the upper mounting groove, a threaded rod is toothedly mounted on the inner side of the internal thread block, a bearing is mounted at the bottom of the threaded rod, the bottom of the bearing is fixedly mounted on the upper surface of the base, and the upper end of the threaded rod passes through the internal thread block and is connected to a turntable.

[0007] Furthermore, a sliding rod is installed on the upper surface of one end of the base, and the upper end of the sliding rod passes through the internal thread block to connect with the limiting block.

[0008] Furthermore, the air outlet pipe is installed on the upper surface of the base, an air cavity is arranged inside the air outlet pipe, an air outlet is opened on the inner wall of the air outlet pipe, and the air outlet is arranged in multiple groups.

[0009] Furthermore, a feed port is provided at one end of the air outlet pipe, a discharge port is provided at the other end of the air outlet pipe, an air inlet pipe is installed on the surface of the air outlet pipe, and one end of the air inlet pipe is connected to the interior of the air cavity.

[0010] Furthermore, mounting frames are fixedly mounted on the upper surfaces of both ends of the base, and rollers are mounted on the inner sides of the upper ends of the mounting frames.

[0011] Furthermore, grooves are provided on both sides of the upper mounting groove and the lower mounting groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The threaded rod is driven to rotate by rotating the turntable, and the rotation of the threaded rod drives the internal thread block to move downward. The downward movement of the internal thread block drives the upper mounting groove and the upper absorbent cotton to follow the movement. The upper absorbent cotton is continuously moved downward to make it close to the upper surface of the lower absorbent cotton, so that the magnetic strip is wrapped around the inner side of the upper absorbent cotton and the lower absorbent cotton. When the magnetic strip winding device continuously drives the magnetic strip to move, the moisture on the surface of the magnetic strip can be absorbed, thereby avoiding the magnetic strip being in a humid environment after winding, which may cause its surface to rust or corrode for a long time, thus affecting its use effect.

[0014] 2. By connecting the air inlet pipe, the air flow fills the inside of the air cavity and finally sprays out through the air outlet to dry the water stains remaining on the surface of the magnetic strip, thus avoiding the magnetic strip being in a humid environment during winding, which may cause rust.
