Description

Technical Field

[0001] This application relates to the technical field of support devices, and in particular to a screw support device for a cable extruder. Background Technology

[0002] Extrusion molding equipment mainly consists of two parts: the main machine and the auxiliary machine. The main machine is called the extruder, which is composed of the extrusion system screw, barrel, feeding device, etc. The screw, as the heart of the extruder, has a very important impact on the quality and output of the extruded products. The main functions of a screw are to convey materials, transfer heat and plasticize materials, and mix and homogenize materials.

[0003] Because the screw on an extruder is quite long, it is usually equipped with a screw support device. However, different screw lengths require different screw support devices, which is quite troublesome. Utility Model Content

[0004] To accommodate screws of different lengths, this application provides a screw support device for a cable extruder.

[0005] This application provides a screw support device for a cable extruder, which adopts the following technical solution: it includes a frame, on which a support component is provided, and the support component is reciprocatingly slidably connected to the frame along the length direction of the screw.

[0006] By adopting the above technical solution, the support assembly can slide back and forth along the length of the screw according to the different length dimensions of different screws, so that the support assembly can be adapted to screws of different length dimensions.

[0007] Preferably, the support assembly is provided in at least two sets, and the multiple sets of the support assembly are spaced apart on the frame along the length direction of the screw, and the multiple sets of the support assembly slide back and forth independently along the length direction of the screw.

[0008] By adopting the above technical solution, when the screw length is long, one support component is not enough to provide a relatively stable support force to the screw. Multiple support components slide and adjust their positions according to the length of the screw to provide a balanced and stable support force to the screw.

[0009] Preferably, the support assembly includes a support bracket and a support rod, the support rod being coaxially arranged with the support bracket and positioned directly below the support bracket, the end of the support rod away from the support bracket being used for reciprocating sliding connection with the frame, and the end of the support bracket away from the support rod being used to support the screw.

[0010] By adopting the above technical solution, the support rod carries the screw, and the support rod slides back and forth along the length of the screw to achieve adaptation to screws of different lengths.

[0011] Preferably, the support assembly further includes a load-bearing slider, which is reciprocatingly and positionably connected to the frame. The load-bearing slider reciprocates along the length of the screw, and the end of the support rod away from the support bracket is coaxially inserted through the load-bearing slider. The support rod is reciprocatingly and positionably connected to the load-bearing slider in a vertical direction.

[0012] By adopting the above technical solution, the load-bearing slider slides back and forth along the length of the screw, and the support rod slides back and forth along the vertical direction and is connected to the load-bearing slider, so that the support can be adapted not only to screws of different lengths, but also to screws of different diameters.

[0013] Preferably, a guide sleeve extends vertically from the upper surface of the bearing slider, the guide sleeve is coaxially threaded onto the support rod, the outer wall of the support rod is circumferentially threaded, and the inner wall of the guide sleeve is threaded with a matching thread that is compatible with the connecting thread.

[0014] By adopting the above technical solution, the matching thread on the inner wall of the guide sleeve and the connecting thread on the outer wall of the support rod are matched, and the height of the support rod can be adjusted in the vertical direction by rotating the support rod.

[0015] Preferably, an adjusting sleeve is fixedly sleeved on the support rod, the adjusting sleeve is located between the support support and the guide sleeve along the axial direction of the support rod, and an adjusting rod is arranged on the wall of the adjusting sleeve along the radial direction of the adjusting sleeve.

[0016] By adopting the above technical solution, the torque is equal to the force multiplied by the lever arm. With the adjustment rod installed, the lever arm of the applied force is greater than the lever arm of the applied force directly acting on the support bracket. The operator can adjust the vertical height of the support rod with less force.

[0017] Preferably, at least one adjusting rod is provided, and a plurality of adjusting rods are provided at equal angular intervals on the wall of the adjusting sleeve along the circumference of the adjusting sleeve.

[0018] By adopting the above technical solution, the setting of multiple adjustment rods allows the operator to adjust the height of the support bracket by moving the adjustment rods in a fixed position, without having to rotate around the support rod.

[0019] Preferably, the bottom of the frame is provided with four casters, which are arranged in a rectangular shape at the bottom of the frame.

[0020] By adopting the above technical solution, four omnidirectional wheels arranged in a rectangle at the bottom of the frame facilitate the movement of the support device by the operator.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The support assembly slides back and forth along the length of the screw, so that the support assembly can be adapted to screws of different lengths;

[0023] 2. The load-bearing slider slides back and forth along the length of the screw, and the support rod slides back and forth vertically and is connected to the load-bearing slider, so that the support can be adapted not only to screws of different lengths, but also to screws of different diameters.

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] This application discloses a screw support device for a cable extruder, which is adapted to screws of different lengths.

[0030] refer to Figure 1 , Figure 2 A screw support device for a cable extruder includes a frame 1. In this embodiment, the frame 1 includes a base frame 11, four vertical rods 12, and two crossbeams 13. The base frame 11 consists of two horizontal base rods 111 and two vertical base rods 112. The two horizontal base rods 111 and the two vertical base rods 112 are connected vertically in sequence to form a rectangular structure. The four vertical rods 12 are arranged in a rectangular distribution on the two horizontal base rods 111. The length direction of the two crossbeams 13 is parallel to the length direction of the screw 101. The bottom of each crossbeam 13 is connected to the two vertical rods 12. The bottom of the frame 1 is provided with four casters 14. The four casters 14 are arranged in pairs. The two casters 14 in a pair are respectively arranged at both ends of a horizontal base rod 111. The four casters 14 are arranged in a rectangular distribution, which facilitates the operator to move the support device.

[0031] Because the screw 101 on the extruder is relatively long, a support assembly 2 is provided on the frame 1. The support assembly 2 includes a support bracket 21, a support rod 22, and a load-bearing slider 23. The support rod 22 is coaxially arranged with the support bracket 21 and is located directly below the support bracket 21. The end of the support bracket 21 away from the support rod 22 is used to support the screw 101. The end of the support rod 22 away from the support bracket 21 is coaxially inserted into the load-bearing slider 23. The load-bearing slider 23 is reciprocally slidably connected to the frame 1 in a positionable manner. The load-bearing slider 23 reciprocates along the length of the screw 101. The support rod 22 is reciprocally slidably connected to the load-bearing slider 23 in a vertical direction. The support assembly 2 can be adapted to screws 101 of different lengths and diameters.

[0032] When the screw 101 is long, one support component 2 is not enough to provide a relatively stable support force to the screw 101. Therefore, in this embodiment, two sets of support components 2 are provided. The two sets of support components 2 are arranged at intervals on the frame 1 along the length direction of the screw 101, and the two sets of support components 2 slide back and forth independently along the length direction of the screw 101 to provide a balanced and stable support force to the screw 101.

[0033] Specifically, the sliding block 23 has sliding strips 24 extending towards the two side walls of the two crossbeams 13 respectively. Sliding grooves 25 are provided on the opposite side walls of the two crossbeams 13. The length direction of the sliding grooves 25 is parallel to the length direction of the crossbeams 13. The two sliding grooves 25 are respectively used for the two sliding strips 24 to slide and be embedded.

[0034] Furthermore, multiple positioning holes 26 are provided on the opposite sides of the two crossbeams 13. The positioning holes 26 are connected to the sliding grooves 25. The multiple positioning holes 26 are equally spaced along the length of the crossbeams 13. Four positioning bolts 27 are passed through the crossbeams 13. After passing through the positioning holes 26, the positioning bolts 27 enter the sliding grooves 25 and are threaded into the slide bars 24. Each slide bar 24 corresponds to two positioning bolts 27. The positioning bolts 27 make the support assembly 2 fixed to the frame 1 after the position is adjusted along the length of the screw 101.

[0035] refer to Figure 2 , Figure 3 In order to achieve the effect of reciprocating sliding of the support rod 22 in a vertically positionable manner, a guide sleeve 28 extends vertically on the upper surface of the bearing slider 23. The guide sleeve 28 is coaxially threaded onto the support rod 22. The outer wall of the support rod 22 is provided with a connecting thread 31 in the circumferential direction. The inner wall of the guide sleeve 28 is provided with a matching thread 32 that matches the connecting thread 31. The height of the support rod 22 in the vertical direction can be adjusted by rotating the support rod 22.

[0036] To facilitate the operator's adjustment of the height of the support rod 22, an adjusting sleeve 33 is fixedly sleeved on the support rod 22. The adjusting sleeve 33 is located between the support support 21 and the guide sleeve 28 along the axial direction of the support rod 22. An adjusting rod 34 is arranged radially on the wall of the adjusting sleeve 33. In this embodiment, four adjusting rods 34 are arranged on the adjusting sleeve 33. The four adjusting rods 34 are arranged at equal angles along the circumference of the adjusting sleeve 33 on the wall of the adjusting sleeve 33. The torque is equal to the force multiplied by the lever arm. With the adjusting rods 34, the lever arm of the applied force is greater than the lever arm of the applied force directly acting on the support support 21. The operator can adjust the height of the support rod 22 in the vertical direction with a smaller amount of force.

[0037] The implementation principle of the screw support device for a cable extruder in this application embodiment is as follows: the operator can adjust the position and height of the support component 2 along the length direction of the screw 101 according to the different lengths and diameters of different screws 101, so as to adapt to the different sizes of the screw 101.

[0038] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
