[0002] In the prior art, an extruder is the main equipment for producing cables. During the actual production process of cables, a vacuum extraction device is set at the head of the extruder to evacuate the cavity of the extruder head to a vacuum, so that the rubber material can fit more tightly on the surface of the wire core.

[0003] In the prior art, the vacuum extraction device usually consists of a suction fan and a steel wire hose connected between the extruder and the suction fan. By turning on the suction fan, the vacuum extraction effect inside the extruder head can be achieved. However, during the actual production process, on-site operators cannot accurately judge the vacuum degree inside the extruder head, making it difficult to control the wrapping degree of the sheath on the wire core, resulting in an increase in the quality fluctuation of the cable. In addition, the service life of the steel wire hose is low. After long-term use, the pipe body is prone to aging and damage, the noise is large during the operation process, and the disassembly and assembly process is cumbersome. Therefore, improvements are urgently needed. Utility Model Content

[0019] Combined as Figures 1-3 As shown, the technical solution is further described. A vacuum visualization and adjustable device for an extruder includes an extruder head 1, a vacuum pump 2, a vacuum pipe 3 provided between the vacuum pump 2 and the extruder head 1, and a vacuum pressure gauge 4 provided on one side of the vacuum pump 2 close to the vacuum pipe 3. The vacuum pump 2 is used to extract the air in the inner cavity of the extruder head 1 through the vacuum pipe 3. When the vacuum pump 2 is connected to the extruder head 1 through the vacuum pipe 3, the vacuum pressure gauge 4 is used to display the pressure value in the extruder head 1.

[0020] The present application provides a vacuum visualization and adjustable device for an extruder, which includes an extruder head, a vacuum pump, a vacuum pipe located between the extruder head and the vacuum pump, and a vacuum pressure gauge provided on one side of the vacuum pump close to the vacuum pipe. By connecting the vacuum pump and the extruder head through a pipeline, the air inside the extruder head is extracted, and a vacuum pressure gauge is provided on one side of the vacuum pump close to the vacuum pipe to display the pressure inside the extruder head, so that the on-site operator can accurately judge the vacuum degree inside the extruder head, thereby controlling the wrapping degree of the sheath around the core, improving the quality of the cable, reducing the cable rework cost, and having the advantages of easy installation, low implementation cost, simple operation, and easy promotion and implementation.

[0021] During the implementation of this embodiment, a pressure adjustment knob 8 is provided between the vacuum pressure gauge 4 and the vacuum pump 2, and the pressure adjustment knob 8 is used to adjust the pressure in the vacuum pipe 3.

[0022] In the actual implementation process, when extruding rubber compound through the head of the extruder, the operator first connects the vacuum extraction pipe to the inner cavity of the extruder head, and then turns on the vacuum extraction machine. The vacuum extraction machine can extract the air in the inner cavity of the extruder head through the vacuum extraction pipe, so that the rubber compound adheres to the surface of the core wire. The on-site operator adjusts the pressure adjustment knob according to the adhesion degree of the rubber compound at the end of the cable completed by extrusion, and records the data of the vacuum pressure gauge, so that the subsequent operator can more easily find the appropriate vacuum extraction pressure.

[0023] In the actual implementation process, an installation pipe is provided on one side of the vacuum extraction machine close to the vacuum extraction pipe, and the vacuum pressure gauge is detachably arranged thereon. A sealing sleeve is provided between the installation pipe and the vacuum pressure gauge. When the vacuum pressure gauge is properly arranged in the installation pipe, the sealing sleeve is used to isolate the outside air from the installation pipe. When the extruder stops, the vacuum pressure gauge can be quickly disassembled to avoid damage to the vacuum pressure gauge.

[0024] In the implementation process of this embodiment, the vacuum extraction pipe 3 is a corrugated braided pipe.

[0025] In the actual implementation process, the vacuum extraction pipe is a PE double-wall plastic braided corrugated pipe. By using the corrugated braided pipe to replace the steel wire hose used in the prior art, the service life of the vacuum extraction device can be effectively extended, the aging and damage of the pipe body after long-term use of the vacuum extraction pipe can be avoided, the noise generated by the collision of the steel wire hose with the ground or wall during the production process of the extruder can be reduced, and it has the advantages of high flexibility and convenient pipeline installation.

[0026] In the implementation process of this embodiment, a first connection assembly 5 is provided between one end of the vacuum extraction pipe 3 and the extruder head 1. The first connection assembly 5 includes a first connection part 50 provided on the extruder head 1 and communicating with its inner cavity, and a hydraulic joint 51 provided at one end of the vacuum extraction pipe 3. The first connection part 50 can be properly arranged in the hydraulic joint 51 so that the vacuum extraction pipe 3 can be detachably arranged on the extruder head 1.

[0027] In the implementation process of this embodiment, a second connection assembly 6 is provided between the other end of the vacuum extraction pipe 3 and the vacuum extraction machine 2. The second connection assembly 6 includes a second connection part 60 provided on the vacuum extraction machine 2 on the side close to the extruder head 1, a pipe sleeve 61 provided at the other end of the vacuum extraction pipe 3, and a pipe clamp 62 provided on the pipe sleeve 61. When the second connection part 60 is properly arranged in the pipe sleeve 61, the pipe clamp 62 is used to make the inner wall of the pipe sleeve 61 closely fit with the outer wall of the second connection part 60.

[0028] In the implementation process of this embodiment, a partition net 7 is provided between the hydraulic joint 51 and the first connection part 50. The partition net 7 is used to prevent solid particles in the extruder head 1 from entering the vacuum extraction pipe 3.

[0029] During the implementation of this embodiment, the partition net 7 is a flexible iron wire net, and the aperture of the mesh of the partition net 7 is 0.1 - 0.6 cm.

[0030] During the actual implementation process, the aperture of the mesh of the partition net 7 is 0.2 cm. By setting the partition net, during the process of the vacuum pump evacuating the air, it can effectively prevent the solid particles in the extruder head from entering the vacuum pump through the vacuum pipe, and avoid the damage of the impeller of the vacuum pump by the solid particles.

[0031] During the implementation of this embodiment, the pipe clamp 62 includes an annular main body 620, a connection notch 621 provided on the annular main body 620, a connection hole provided on the annular main body 620 at a position corresponding to the connection notch 621, and a fastener 622 fitted in the connection hole. The pipe sleeve 61 can be inserted into the annular main body 620 through the connection notch 621, and the fastener 622 is used to drive the two ends of the connection notch 621 to move towards or away from each other, so that the inner wall of the pipe sleeve 61 moves towards or away from the outer wall of the second connection part 60.

[0032] During the actual implementation process, the material of the pipe clamp is glass fiber modified polypropylene resin, which has the advantages of high strength and light weight. When used in cooperation with the corrugated braided pipe, it can improve the pipeline installation efficiency and reduce the labor loss during the pipeline handling process.

[0033] This application provides a visual and adjustable device for vacuum extraction of an extruder, which includes an extruder head, a vacuum pump, a vacuum pipe located between the extruder head and the vacuum pump, and a vacuum pressure gauge provided on the vacuum pump near the vacuum pipe. By connecting the vacuum pump and the extruder head with pipelines, the air inside the extruder head is extracted, and a vacuum pressure gauge is provided on the side of the vacuum pump near the vacuum pipe to display the pressure inside the extruder head, so that the on-site operator can accurately judge the vacuum degree inside the extruder head, and then control the wrapping degree of the sheath on the wire core, improving the quality of the cable, reducing the cable rework cost. It has the advantages of reasonable design, delicate structure, simple structure, low cost, durability, greatly facilitating the adjustment of the rubber compound fitting degree by the operating workers during the production process of the product, and reducing the rework cost.
