Description

Technical Field

[0001] This utility model relates to the field of cable production technology, specifically to a cable sheath extrusion device. Background Technology

[0002] The main function of cable sheath extrusion equipment is to uniformly wrap plastic or other materials around the conductor or core of the cable to form a continuous sheath. This process usually involves the use of an extruder, which pushes plastic or other materials into the die head through a screw. Then, under the action of the die head mold, the material is plasticized and extruded into the required shape and thickness, and finally wrapped around the cable.

[0003] Chinese patent CN217021361U addresses the problem of uneven feeding and easy blockage of materials in existing thermoplastic extrusion equipment for cable sheath production, which affects the working efficiency of the equipment due to the use of a conical channel for feeding. The proposed solution includes a base with a mounting platform fixedly installed on its top. A connecting block, which is hollow, is fixedly installed on the inner left wall of the connecting block, and the left end of the extrusion cylinder extends to the left side of the connecting block and is fixedly installed with an extrusion head. Compared to conventional thermoplastic extrusion equipment for cable sheath production, this invention allows for rotating feeding of the anti-blocking shaft and anti-blocking plate, resulting in more uniform material addition and preventing blockages during feeding, thus improving the working efficiency of the thermoplastic extrusion equipment.

[0004] The aforementioned patented solution involves feeding material into the cable sheath extrusion equipment via a feed tube. However, it is difficult to ensure uniform material feeding during this process. Uneven feeding can easily cause inconsistent thickness of the inner wall of the cable sheath. In addition, the material may also cause blockage inside the feed tube, thereby affecting the extrusion quality of the cable sheath. Utility Model Content

[0005] The purpose of this invention is to provide a cable sheath extrusion device to solve the problems mentioned in the background art, such as the difficulty in ensuring uniform material delivery, uneven feeding, inconsistent thickness of the inner wall of the cable sheath, and the possibility of material blockage inside the feed pipe, thereby affecting the extrusion quality of the cable sheath.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution: a cable sheath extrusion device, including a processing table 1, a feed pipe 2 fixedly installed at the top right end of the processing table 1, and a partition net 3 fixedly installed inside the feed pipe 2.

[0023] Please see Figure 1 , Figure 2 and Figure 4An L-shaped plate 4 is fixedly installed on the top left end of the processing table 1. A servo motor 5 is fixedly installed on one side of the L-shaped plate 4. A small pulley 6 is fixedly installed on the output end of the servo motor 5. A large pulley 7 is connected to one side of the small pulley 6 via a belt drive. A scraper 8 is fixedly installed on the top edge of the large pulley 7. The other end of the scraper 8 extends into the feed pipe 2 and contacts the surface of the mesh 3. The large pulley 7 is rotatably connected to the top right end of the processing table 1. A cooling water tank 9 is fixedly installed on the left end of the processing table 1. An extrusion cylinder 10 is fixedly installed at the bottom of the feed pipe 2. The extrusion cylinder 10 is arranged inside the extrusion cylinder 10 in a left-right direction. The left end of the extrusion cylinder 10 extends through to the outside of the left end of the processing table 1. An extrusion assembly 11 is arranged inside the processing table 1. An exhaust assembly 12 is arranged on the rear side of the processing table 1. One end of the exhaust assembly 12 is connected to the extrusion cylinder 10.

[0024] In use, the small pulley 6 drives the large pulley 7 to rotate via a belt, which in turn drives the scraper 8 to adjust. This process allows the other end of the scraper 8 to slide smoothly on the surface of the mesh 3, effectively controlling the feeding speed of the mesh 3 and ensuring the uniformity of feeding. At the same time, it also prevents clogging on the surface of the mesh 3, thereby ensuring the stability of the cable sheath extrusion process and ensuring the processing progress.

[0025] Please see Figure 1 and Figure 2 In some embodiments, the extrusion assembly 11 includes a drive motor 111, which is fixedly mounted on the right end face of the processing table 1. A pinion 112 is fixedly mounted on the output end of the drive motor 111. A large gear 113 is meshed with one side of the pinion 112. Both the large gear 113 and the pinion 112 are rotatably connected to the outer wall of the right end of the processing table 1. A connecting shaft 114 is fixedly inserted through the axis of the pinion 112. The left end of the connecting shaft 114 rotatably extends through to the right end of the extrusion cylinder 10. A spiral blade 115 is fixedly mounted on the left end of the connecting shaft 114. The spiral blade 115 is rotatably disposed inside the extrusion cylinder 10. Cable transmission holes 116 are provided inside both the spiral blade 115 and the connecting shaft 114.

[0026] The extrusion cylinder 10 has an internal heating structure, and the outer wall of the spiral blade 115 slides in contact with the inner wall of the extrusion cylinder 10. This equipment uses the spiral blade 115 to propel and transport the material, gradually turning it into a viscous fluid and uniformly plasticizing it during the heating process.

[0027] In some embodiments, the exhaust assembly 12 includes a mounting plate 121, which is fixedly mounted on the rear side of the processing table 1. A vacuum pump 122 is fixedly mounted on the top of the mounting plate 121. A purifier 123 is fixedly mounted at the input end of the vacuum pump 122. An activated carbon adsorption mesh 124 is fixedly mounted at the input end of the purifier 123. A transmission pipe 125 is fixedly mounted on the other side of the activated carbon adsorption mesh 124. A filter screen 126 is fixedly mounted inside the transmission pipe 125. The other end of the transmission pipe 125 extends through into the interior of the extrusion cylinder 10.

[0028] When in use, the exhaust assembly 12 can effectively purify and discharge the toxic gases generated during the hot melting process of the material. This not only helps the material processing but also prevents workers from inhaling toxic gases, thus protecting their health and making the use of cable sheath extrusion equipment safer.

[0029] Working principle: The staff pours the material into the feed pipe 2, and then starts the servo motor 5. The servo motor 5 drives the small pulley 6 to rotate. The small pulley 6 drives the large pulley 7 to rotate through the belt drive. The large pulley 7 then drives the scraper 8 to adjust, ensuring that the scraper 8 effectively promotes the material transfer to the inside of the extrusion cylinder 10 on the surface of the mesh 3.

[0030] Next, the heating structure inside the extrusion cylinder 10 is activated to heat the material. Simultaneously, the drive motor 111 is activated, causing the pinion 112 to rotate. The pinion 112 drives the large gear 113 to rotate, which in turn drives the connecting shaft 114 to rotate. The connecting shaft 114 then drives the spiral blade 115 to rotate. The spiral blade 115 gradually transforms the material into a viscous fluid and uniformly plasticizes it. The viscous fluid is then pushed towards the die head and shaped into the required size and shape through the mold. Simultaneously, a cable enters from the right end of the transfer hole 116 and then exits from the left end of the extrusion cylinder 10 into the die head mold, ensuring that the shaped viscous fluid coats the wire core or conductor. Furthermore, the cooling water tank 9 provides cooling.

[0031] During the thermal reaction, the vacuum pump 122 is started, which transfers the gas inside the extrusion cylinder 10 to the activated carbon adsorption net 124. After the activated carbon adsorption net 124 filters the gas, it is then transferred to the purifier 123, which thoroughly purifies and discharges the toxic gas.

[0032] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
