Description

Technical Field

[0001] The utility model relates to the technical field of cable material production, in particular to a filtering device for cable material production. Background Art

[0002] Cables usually consist of parts such as conductors, insulating layers, and sheaths. Corresponding cable materials include metal materials for forming conductors, such as copper, aluminum, etc.; insulating materials, such as polyethylene, polyvinyl chloride (PVC), rubber, etc.; and materials for making sheaths, like polyethylene, polyvinyl chloride, nylon, etc. These materials need to possess good electrical conductivity, insulation performance, mechanical strength, corrosion resistance, heat resistance, etc. characteristics to ensure that the cable can safely and stably transmit electricity or signals under different environments and usage conditions.

[0003] In the process of continuous industrial development, the requirements for the quality of PVC particles used in cable material production are increasing day by day. In the melt, the number of impurities directly affects the quality of PVC particles for optical fibers. However, for the filtering devices equipped in existing general PVC granulators, the impurity passing rate is relatively high, making it difficult to meet the requirements for the quality of PVC particles for optical fibers. In addition, the PVC filter mesh needs to be replaced frequently. The existing filtering devices are not only difficult to disassemble and assemble, but also prone to blockage, and the working efficiency is extremely low. Summary of the Utility Model

[0004] In order to solve the above various problems, the utility model proposes a filtering device for cable material production that is convenient for replacing the filter mesh and has good hot melt transmission effect.

[0005] To solve the above technical problems, the technical solution proposed by the utility model is: a filtering device for cable material production, including a base. Horizontally and sequentially arranged above the base are a hot melt box, a feed box, and a discharge box. A conveyer pipe that can be communicated is arranged in the feed box and the discharge box. The conveyer pipe in the hot melt box is communicated with that in the feed box. A screw conveyor is rotatably connected in the hot melt box, and the other end of the screw conveyor extends into the conveyer pipe. The screw conveyor is driven by a motor I fixed on the hot melt box. A filter disc is rotatably arranged on one side of the feed box close to the discharge box. The filter disc is driven by a motor II fixed above the feed box. A number of filter holes corresponding to the conveyer pipe are arranged on the filter disc. A detachable filter mesh is arranged in the filter holes. The discharge box is slidably arranged on the base and is driven by an electric push rod fixed on the base. A discharge pipe communicated with the conveyer pipe is connected to one side of the discharge box.

[0006] Further, a hot melt mechanism is arranged in the hot melt box, and a feed hopper is connected above the hot melt box.

[0007] Based on the above features, the hot melting mechanism can ensure the hot melting effect, enabling the material to reach an ideal hot melting state. The setting of the feed hopper facilitates the addition of the material, ensuring the continuous progress of the hot melting process and improving the production efficiency.

[0008] Further, a plurality of heat dissipation holes are provided on the side walls and the upper walls of the feed box and the discharge box.

[0009] Based on the above features, the heat dissipation holes can promote the heat dissipation of the device, avoiding the danger caused by excessive temperature during the material production process.

[0010] Further, the filter screen is fixedly arranged in the filter holes through a plurality of screws.

[0011] Based on the above features, it is convenient to disassemble and replace the filter screen.

[0012] Further, sliding strips are symmetrically arranged below the discharge box, and sliding grooves for cooperating with the sliding strips are provided on the base.

[0013] Based on the above features, the cooperation of the sliding strips and the sliding grooves can enable the discharge box to move stably on the base, ensuring the accurate docking of the two conveying pipes, thereby ensuring the stable conveying of the cable material.

[0014] Further, arc-shaped grooves are provided around the filter holes on the filter disc. A positioning protrusion for cooperating with the arc-shaped grooves is connected to the side of the discharge box close to the feed box and at the port of the conveying pipe. A sealing gasket is provided on the positioning protrusion.

[0015] Based on the above features, the cooperation of the arc-shaped grooves and the positioning protrusions can ensure the precise docking of the port of the conveying pipe and the filter holes. The cooperation with the sealing gasket can ensure the sealing performance of the docking position, which is beneficial to the stable conveying of the cable material.

[0016] The advantages of the present utility model compared with the prior art are as follows: A detachable filter screen is arranged in the filter holes on the filter disc, and the filter screen is fixed by a plurality of screws. When the filter screen needs to be replaced, only the screws need to be unscrewed to easily remove the old filter screen and install a new one. This fixing method is simple and reliable, and the operation is convenient. Moreover, the filter disc is driven by the second motor to rotate, which enables the filter disc to be rotated to a suitable position when replacing a certain filter screen, and other filter screens can be used for filtering, facilitating the operation of the operator, improving the efficiency and convenience of replacement, and greatly reducing the impact on the production process caused by replacing the filter screen; A screw conveyor is arranged in the hot melting box and is driven by the first motor. The rotation of the screw conveyor can effectively stir and push the material, making the material evenly heated in the hot melting box, ensuring the hot melting effect, and thus realizing the uniform and stable transmission of the material.
