Description

Technical Field

[0001] The present application relates to the technical field of cable production equipment, and in particular to an extruder auxiliary traction device for preventing cable shaking. Background Art

[0002] A cable extruder is a key piece of equipment used in the production of cable insulation and sheathing. It primarily propels raw materials, such as plastic pellets, through a rotating screw. Heat and shear melt and plasticize the materials, which are then extruded through a specific die to form a continuous cable sheath.

[0003] During the use of the extruder, the coated cable needs to be straightened to prevent the cable from shaking and to make the cable move forward. However, since the molten plastic has not completely cooled, directly pulling the cable may cause the plastic to deform, resulting in incomplete plastic wrapping. Utility Model Content

[0004] In order to enable the extruder to provide better traction for the cable when in use, the present application provides an extruder auxiliary traction device that prevents the cable from shaking.

[0005] The above technical objectives of this application are achieved through the following technical solutions:

[0006] The traction structure and the cooling structure are both arranged above the bracket. The traction structure includes an upper traction structure and a lower traction structure. The upper traction structure includes an upper conveyor frame, an upper pulley and an upper conveyor belt. Two upper pulleys are provided. The upper pulleys are connected to a driving structure. The two upper pulleys are rotatably connected to the two ends of the upper conveyor frame. The upper conveyor belt is wrapped around the outside of the upper pulley. The lower traction structure includes a lower conveyor frame, a lower pulley and a lower conveyor belt. Two lower pulleys are provided. The lower pulleys are connected to a driving structure. The two lower pulleys are rotatably connected to the two ends of the lower conveyor frame. The lower conveyor belt is wrapped around the outside of the lower pulley. The upper conveyor belt and the lower conveyor belt are respectively located on opposite sides of the cable. The cooling structure is provided between the traction structure and the extruder.

[0007] By adopting the above solution, when the cable surface is wrapped with plastic, the cable first passes through the cooling structure to completely solidify the plastic on the cable surface, and then the cable passes between the upper traction structure and the lower traction structure. The driving structure drives the upper pulley and the lower pulley to rotate, thereby driving the upper conveyor belt and the lower conveyor belt to rotate, thereby driving the cable to move. The contact area between the upper conveyor belt and the lower conveyor belt and the cable is larger, so that the force on the cable is more uniform, so that the plastic on the cable surface is less likely to deform, and the cable is also less likely to shake.

[0008] Optionally, arc-shaped line grooves are provided on the surfaces of the upper conveyor belt and the lower conveyor belt.

[0009] By adopting the above solution, arc-shaped line grooves are opened on the surfaces of the upper conveyor belt and the lower conveyor belt, so that the cables are located in the line grooves when passing through the upper traction structure and the lower traction structure, thereby further increasing the contact area between the cables and the traction structure.

[0010] Optionally, the lower conveying rack is fixedly connected to the bracket, a hinged plate is rotatably connected above the bracket, the hinged plate is fixedly connected to the upper conveying rack, and the upper conveying rack is connected to a clamping structure.

[0013] By adopting the above solution, when installing the cable, the upper traction structure can be opened first, the cable can be placed above the lower conveyor belt, and then the upper traction structure can be closed, so that the clamping rod is inserted into the clamping groove, and the clamping rod presses the clamping pin into the pin groove, and the spring is compressed at the same time until the upper clamping block and the lower clamping block are completely closed. At this time, the clamping pin is facing the clamping groove, and the spring rebounds to drive the clamping pin into the clamping groove, thereby clamping the clamping rod in the clamping groove, thereby clamping the upper traction structure and the lower traction structure, making it more convenient to place the cable between the upper traction structure and the lower traction structure.

[0014] Optionally, a sliding hole is provided at the bottom of the groove of the clamping rod, a sliding rod is slidably connected in the sliding hole, one end of the sliding rod passes through the upper clamping block, and the other end of the sliding rod is fixedly connected to the bayonet pin.

[0015] By adopting the above solution, when the cable needs to be removed, the sliding rod can be pulled to drive the latch pin to slide out of the slot, so that the connecting rod can slide out of the connecting slot, thereby opening the upper traction structure, and then the cable can be taken out, making it more convenient to take the cable.

[0016] Optionally, the cooling structure includes a cooling pipe and a fan, the cable passes through the cooling pipe, and the cooling pipe is connected to a ventilation pipe, and the fan is connected to the inside of the cooling pipe through the ventilation pipe.

[0017] By adopting the above solution, the fan allows wind to enter the cooling pipe along the ventilation pipe, thereby accelerating the air flow rate in the cooling pipe, thereby accelerating the cooling of the cable.

[0018] Optionally, the cooling pipe includes an upper cooling pipe and a lower cooling pipe, the ventilation pipe is connected to the lower cooling pipe, the lower cooling pipe is fixedly connected to the bracket, and the upper cooling pipe is fixedly connected to the hinged plate.

[0019] By adopting the above solution, it is more convenient for operators to put the cables into the cooling pipe.

[0020] Optionally, one end of the ventilation pipe connected to the cooling pipe is fixedly connected to an air guide pipe, and the air guide pipe is an air guide pipe that allows the wind to enter the cooling pipe in a spiral path along the cooling pipe.

[0021] By adopting the above solution, the air duct makes the air flow path spiral, preventing the wind from directly blowing onto the cable surface and causing deformation of the plastic.

[0022] In summary, this application has the following technical effects:

[0023] 1. The cooling structure is set to accelerate the cooling of the cable plastic, and the upper and lower traction structures are used to pull the cable, so that the extruder can provide better traction for the cable when in use;

DETAILED DESCRIPTION

[0031] The present application is further described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1 A secondary traction device for an extruder to prevent cable vibration is characterized by comprising a bracket 1, a traction structure, and a cooling structure 4. The traction structure and cooling structure 4 are both arranged above the bracket 1. The traction structure includes an upper traction structure 2 and a lower traction structure 3. The cooling structure 4 is arranged between the traction structure and the extruder. When the surface of the cable 6 is wrapped with plastic, the cable 6 first passes through the cooling structure 4 to completely solidify the plastic on the surface of the cable 6. The cable 6 is then passed between the upper traction structure 2 and the lower traction structure 3. The traction structure and the lower traction structure 3 simultaneously pull the cable 6, increasing the contact area between the cable 6 and the traction structure, thereby further dispersing the force acting on the cable 6 and further reducing the plastic on the surface of the cable 6 from deformation.

[0033] Reference Figure 1 The traction structure includes an upper traction structure 2 and a lower traction structure 3. The upper traction structure 2 includes an upper conveyor frame 21, an upper pulley 22 and an upper conveyor belt 23. There are two upper pulleys 22, which are connected to a driving structure. The two upper pulleys 22 are rotatably connected to the two ends of the upper conveyor frame 21, and the upper conveyor belt 23 is wrapped around the outside of the upper pulley 22. The lower traction structure 3 includes a lower conveyor frame 31, a lower pulley 32 and a lower conveyor belt 33. There are two lower pulleys 32, which are connected to a driving structure. The two lower pulleys 32 are rotatably connected to the two ends of the lower conveyor frame 31, and the lower conveyor belt 33 is wrapped around the outside of the lower pulley 32. The upper conveyor belt 23 and the lower conveyor belt 33 are respectively located on opposite sides of the cable 6. The cable 6 passes between the upper conveyor belt 23 and the lower conveyor belt 33, and the driving structure drives the upper pulley 22 and the lower pulley 32 to rotate, thereby driving the upper conveyor belt 23 and the lower conveyor belt 33 to rotate, thereby driving the cable 6 to move. The contact area between the upper conveyor belt 23 and the lower conveyor belt 33 and the cable 6 is larger, so that the force exerted on the cable 6 is more uniform, making the plastic on the surface of the cable 6 less likely to deform, and also making the cable 6 less likely to shake.

[0034] In addition, arc-shaped line grooves are provided on the surfaces of the upper conveyor belt 23 and the lower conveyor belt 33, so that the cable 6 is located in the line grooves when passing through the upper traction structure 2 and the lower traction structure 3, thereby further increasing the contact area between the cable 6 and the traction structure.

[0035] Reference Figure 1 and Figure 2 The lower conveying frame 31 is fixedly connected to the bracket 1 , and a hinge plate 11 is rotatably connected above the bracket 1 . The hinge plate 11 is fixedly connected to the upper conveying frame 21 , and the upper conveying frame 21 is connected to a clamping structure 5 . The clamping structure 5 includes an upper clamping block 51 and a lower clamping block 52. The upper clamping block 51 is fixedly connected to the upper conveying frame 21. A lower clamping groove is provided on the lower surface of the upper clamping block 51, and a pin groove is provided on the inner side wall of the clamping groove 511. A clamping pin 513 is slidably connected in the pin groove, and one end of the clamping pin 513 is fixedly connected to a spring 514, and the other end of the spring 514 is fixedly connected to the pin hole of the clamping pin 513, and the clamping pin 513 is inclined away from one end of the spring 514, and the inclined surface of the clamping pin 513 is inclined downward. The lower clamping block 52 is fixedly connected to the lower conveying frame 31, and the lower clamping block 52 is fixedly connected to the clamping rod 521 at the upper end. A clamping groove is provided on the surface of the clamping rod 521. The clamping rod 521 is inserted into the clamping groove 511, and the clamping pin 513 is clamped in the clamping groove 522. When installing the cable 6, the upper traction structure 2 can be opened first, the cable 6 can be placed above the lower conveyor belt 33, and then the upper traction structure 2 can be closed, so that the clamping rod 521 is inserted into the clamping groove 511, and the clamping rod 521 presses the clamping pin 513 into the pin groove 512. At the same time, the spring 514 is compressed until the upper clamping block 51 and the lower clamping block 52 are completely closed. At this time, the clamping pin 513 is facing the clamping groove 522, and the spring 514 rebounds to drive the clamping pin 513 into the clamping groove 522, thereby clamping the clamping rod 521 in the clamping groove 511, thereby clamping the upper traction structure 2 and the lower traction structure 3, making it more convenient to place the cable 6 between the upper traction structure 2 and the lower traction structure 3.

[0036] Reference Figure 2 The bottom of the groove of the connecting rod 521 is provided with a sliding hole 515, and a sliding rod 516 is slidably connected to the sliding hole 515. One end of the sliding rod 516 passes through the upper clamping block 51, and the other end of the sliding rod 516 is fixedly connected to the latch 513. When it is necessary to remove the cable 6, the sliding rod 516 can be pulled, thereby driving the latch 513 to slide out of the clamping groove 522, allowing the connecting rod 521 to slide out of the clamping groove 511, thereby opening the upper traction structure 2, and then the cable 6 can be taken out, making it more convenient to take the cable 6.

[0037] Reference Figure 3 and Figure 4The cooling structure 4 includes a cooling tube 41 and a fan 43. The cable 6 passes through the cooling tube 41, which is connected to a ventilation tube 42. The fan 43 communicates with the interior of the cooling tube 41 through the ventilation tube 42. An air guide 421 is fixedly connected to one end of the ventilation tube 42, which is connected to the cooling tube 41. The air guide 421 is a spiral-shaped air guide 421 that guides air into the cooling tube 41. The fan 43 guides air along the ventilation tube 42 into the cooling tube 41, accelerating the air flow rate within the cooling tube 41 and thus speeding up the cooling of the cable 6. The air guide 421 also creates a spiral air flow path to prevent wind from directly blowing on the surface of the cable 6 and causing plastic deformation.

[0038] Reference Figure 3 and Figure 4 The cooling pipe 41 includes an upper cooling pipe 411 and a lower cooling pipe 412. The ventilation pipe 42 is connected to the lower cooling pipe 412. The lower cooling pipe 412 is fixedly connected to the bracket 1. The upper cooling pipe 411 is fixedly connected to the hinged plate 11, making it more convenient for the operator to place the cable 6 into the cooling pipe 41.

[0039] The specific implementation principle of the present application is: when installing the cable 6, the hinged plate 11 is rotated around the intersection axis, so that the upper cooling tube and the upper traction structure 2 of 411 are opened, and then the cable 6 is placed on the lower cooling tube and the lower traction structure 3, and then the upper cooling tube and the upper traction structure 2 are closed, so that the clamping rod 521 is inserted into the clamping groove 511, and the clamping pin 513 is inserted into the clamping groove 522, so that the upper traction structure 2 and the lower traction structure 3 are clamped, and then the driving structure drives the upper pulley 22 and the lower pulley 32 to rotate, thereby driving the upper conveyor belt 23 and the lower conveyor belt 33 to move, thereby driving the cable 6 to move.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
