[0001] This application belongs to the technical field of cable manufacturing, and specifically relates to a clamping device for the water-cooled head of an extruder screw. Background Art
[0002] In the prior art, extruders are widely used in the production processes of materials such as plastics and rubbers. The water circulation cooling system of an extruder is an indispensable part of the extruder, mainly used for cooling and discharging the heat generated during the extrusion process to ensure the stable operation of the extruder and good plasticization of the rubber compound.
[0003] In the prior art, the cooling system of an extruder mainly cools the extruder by installing a water ring or a water pipe inside the heater and introducing cold water into the water ring or the water pipe. However, in the actual implementation process, the rotary joint at the tail of the screw circulating water system will rotate slightly due to problems such as installation deviation and bearing jamming and wear. After long-term use, the accumulation of rotation will cause the pipeline of the circulating water system to be wound around the rotary joint, resulting in the damage of the entire circulating system. Therefore, improvements are urgently needed to provide a certain supporting force to the rotary joint, thereby protecting the entire circulating system. Summary of the Utility Model
[0004] In order to solve the technical problem in the prior art that the rotary joint at the tail of the circulating water-cooling system rotates slightly during the operation of the extruder due to installation deviation and bearing jamming and wear, and after long-term use, the pipeline of the water-cooling circulating system will be wound around the rotary joint, resulting in the damage of the entire water-cooling circulating system, this application proposes a clamping device for the water-cooled head of an extruder screw.
[0005] This application adopts the following scheme. A clamping device for the water-cooled head of an extruder screw includes a supporting extension arm, a clamping part vertically arranged at one end of the supporting extension arm in the vertical direction, a horizontal supporting beam vertically arranged at the other end of the supporting extension arm in the horizontal direction, and fixing parts arranged at both ends of the horizontal supporting beam. The clamping part is used to clamp the rotary joint to limit the relative rotation of the rotary joint with respect to the extruder, and the fixing parts are used to fix the horizontal supporting beam on the extruder gearbox.
[0006] Furthermore, the clamping part includes a connecting beam vertically arranged at one end of the supporting extension arm, and a clamping groove arranged at the end of the connecting beam far from the supporting extension arm. The rotary joint can be fitted into the clamping groove.
[0007] Furthermore, the fixing part includes a fixing bracket foot arranged at one end of the horizontal supporting beam, and a fixing hole arranged on the fixing bracket foot. A fastener can be fitted through the fixing hole to fix the fixing bracket foot on the extruder gearbox.

[0009] Further, an included angle A is provided between the fixing part and the horizontal support beam, and the degree of the included angle A satisfies the following relationship: 120° ≤ included angle A ≤ 150°.
[0010] Further, the cross-section of the fixing feet is L-shaped.
[0011] Further, a buffer pad is provided on the side of the fixing feet close to the extruder gearbox. The buffer pad is made of silica gel and is used to reduce the vibration of the extruder gearbox on the fixing feet.
[0012] Further, an anti-slip layer is adhered to the inner wall of the clamping groove. The anti-slip layer is made of styrene-butadiene rubber, and anti-slip grooves are recessed at intervals along the length direction of the anti-slip layer.

[0019] Combined as Figures 1-3As shown in the figure, the present technical solution will be further described. A clamping device for the screw water-cooling head of an extruder includes a support extension arm 1, a clamping part 2 vertically arranged at one end of the support extension arm 1 in the vertical direction, a horizontal support beam 3 vertically arranged at the other end of the support extension arm 1 in the horizontal direction, and fixing parts 4 arranged at both ends of the horizontal support beam 3. The clamping part 2 is used to clamp the rotary joint to limit the rotation of the rotary joint relative to the extruder, and the fixing part 4 is used to fix the horizontal support beam 3 to the extruder gearbox.
[0020] The present application provides a clamping device for the screw water-cooling head of an extruder, which includes a support extension arm, a clamping part vertically arranged at one end of the support extension arm, a horizontal support beam arranged at the other end of the support extension arm, and fixing parts arranged at both ends of the horizontal support beam. After using the fixing parts to fix the clamping part to the extruder gearbox, the rotary joint is matched and arranged on the clamping part. The clamping part can abut against the outer periphery of the rotary joint, thereby restricting the rotation of the rotary joint relative to the extruder, avoiding damage to the water-cooling circulation system due to the rotation of the rotary joint, prolonging the service life of the screw water circulation system, and having the advantages of reasonable design, delicate structure, simple structure, convenient processing and manufacturing, low implementation cost, and convenient promotion and implementation.
[0021] During the implementation of this embodiment, the clamping part 2 includes a connecting beam 20 vertically arranged at one end of the support extension arm 1, and a clamping groove 21 arranged at the end of the connecting beam 20 far from the support extension arm 1. The rotary joint can be matched and arranged in the clamping groove 21.
[0022] During the actual implementation process, the support extension arm, the clamping part, the horizontal support beam, the clamping part, and the fixing part are all processed from square steel tubes. The support extension arm, the clamping part, the horizontal support beam, the clamping part, and the fixing part are connected by welding, which has the advantages of convenient pre-processing and manufacturing and convenient use by operators. The operator only needs to screw two screws to complete disassembly and assembly. Using the square steel tube corner materials during production for welding production not only ensures the strength of the clamping device but also reduces the improvement cost, saves materials to the greatest extent, and has the advantage of being convenient for promotion and implementation.
[0023] During the implementation of this embodiment, the fixing part 4 includes a fixing bracket foot 40 arranged at one end of the horizontal support beam 3, and a fixing hole 41 arranged on the fixing bracket foot 40. A fastener can be matched and passed through the fixing hole 41 to fix the fixing bracket foot 40 to the extruder gearbox.
[0024] During the implementation of this embodiment, the fixing bracket foot 40 is inclined relative to the horizontal support beam 3.
[0025] During the implementation of this embodiment, an angle A is provided between the fixing portion 4 and the horizontal support beam 3 , and the degree of the angle A satisfies the following relationship: 120°≤angle A≤150°.
[0026] In the actual implementation process, the angle A = 120°. By setting the angle A between the fixed part and the horizontal support beam, the welding area between the fixed part and the horizontal support beam is increased, the welding strength of the two is improved, and the material is saved to the greatest extent. The process holes on the extruder gearbox can be used for fixing, and the clamping method and position of the clamping part can be adjusted according to the size specifications of the rotary joint. It has strong adaptability and can be adjusted according to the model of the extruder and the size specifications of the rotary joint. It is easy to install and easy to promote and implement.
[0027] During the implementation of this embodiment, the cross-section of the fixed leg 40 is L-shaped.
[0028] During the implementation of this embodiment, a buffer pad is provided on the side of the fixed leg 40 close to the extruder gearbox. The buffer pad is made of silicone and is used to reduce the vibration of the extruder gearbox on the fixed leg 40.
[0029] During the actual implementation, a mounting groove is provided on the side of the fixed bracket close to the extruder gearbox, and a mounting protrusion is matched with the buffer pad at the corresponding position of the mounting groove. The mounting protrusion can be matched and extended into the mounting groove to fix the buffer pad on the fixed bracket. By installing the buffer pad, the vibration generated during the operation of the extruder can be effectively prevented from loosening the fasteners from the fixing holes, so that the fixed bracket can be loosened, thereby causing the rotary joint to deform and cause damage.
[0030] During the implementation of this embodiment, an anti-skid layer is adhered to the inner wall of the clamping groove 21. The material of the anti-skid layer is styrene-butadiene rubber. The anti-skid layer is provided with anti-skid grooves at intervals along its length direction. When the rotary joint is matched in the clamping groove 21, the anti-skid layer is used to prevent the rotary joint from slipping out of the clamping groove 21.
[0031] During the actual implementation process, the anti-slip layer is adhered to the inner wall of the clamping groove through epoxy resin. By setting the anti-slip layer, when the rotary joint is matched and extended into the clamping groove, on the one hand, the anti-slip layer can prevent the surface of the rotary joint from being worn and bumped, and on the other hand, it can improve the clamping stability of the clamping groove, so that the rotary joint will no longer damage the entire system due to rotation, thereby extending the service life of the screw water circulation system.
[0032] The present application provides a clamping device for the water-cooled head of an extruder screw, which includes a supporting extension arm, a clamping part vertically arranged at one end of the supporting extension arm in the vertical direction, a horizontal supporting beam arranged at the other end of the supporting extension arm, and fixing parts arranged at both ends of the horizontal supporting beam. After fixing the clamping part on the extruder gearbox by using the fixing parts, a rotary joint is matched and arranged on the clamping part. The clamping part can abut against the outer periphery of the rotary joint, thereby restricting the rotation of the rotary joint relative to the extruder, avoiding damage to the water-cooling circulation system caused by the rotation of the rotary joint, and prolonging the service life of the screw water circulation system. It has the advantages of reasonable design, delicate structure, simple structure, convenient processing and manufacturing, low implementation cost, and convenient popularization and implementation.
