Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable processing equipment technology, and in particular to a plastic extrusion auxiliary machine. Background Technology
[0002] In the cable manufacturing process, plastic extruders are used to extrude insulation or sheathing materials to form insulation or outer sheaths. A plastic extruder consists of a main extruder and an auxiliary extruder. During the hot-melt or extrusion process of the insulation or sheathing materials, the auxiliary extruder needs to adjust its position according to the changes in the processing steps; therefore, the auxiliary extruder needs to move according to the processing steps of the main extruder.
[0003] Existing auxiliary machines move by means of guide rails and sliders. However, when the main machine heat-melts the insulating or sheathing materials, it generates a large amount of water vapor. The water vapor corrodes the guide rails and sliders. Over time, the corrosion will cause the guide rails and sliders to rust, affecting the smoothness of the auxiliary machine's movement, and may even cause the auxiliary machine to jam during movement.
[0004] Therefore, there is an urgent need for a plastic extrusion auxiliary machine to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this utility model is to provide a plastic extrusion auxiliary machine that can solve the problem that after long-term use, the guide rails and sliders will be corroded and rusted by water vapor, resulting in the auxiliary machine not moving smoothly, or even getting stuck during the movement of the auxiliary machine.
[0006] To achieve this objective, the present invention adopts the following technical solution:
[0007] A plastic extrusion auxiliary machine, comprising:
[0008] The main body and the moving mechanism are located on the bottom surface of the main body. The moving mechanism includes a track, rollers and a connector. The track is laid on the workbench and includes a guide part. The rollers are provided with guide grooves and the guide part is located in the guide grooves.

The roller has a through hole, the bearing is placed in the through hole, the connecting shaft passes through the inner ring of the bearing, and the connecting frame connects the bottom surface of the main body and the connecting shaft.
[0012] As a preferred technical solution for a plastic extrusion auxiliary machine, the through hole includes a first circular hole, a second circular hole, and a third circular hole that are interconnected. The first circular hole and the third circular hole are respectively located at both ends of the second circular hole. The diameters of the first circular hole and the third circular hole are both larger than the diameter of the second circular hole. Two bearings are provided, and the two bearings are respectively located in the first circular hole and the third circular hole.
[0013] As a preferred technical solution for a plastic extrusion auxiliary machine, the connecting frame has a clearance opening, the roller portion is placed inside the clearance opening, the connecting shaft passes through the roller and the connecting frame, the connecting member also includes a locking member, the locking member is used to lock the connecting shaft to the connecting frame, and the top surface of the connecting frame is connected to the main body.

[0017] As a preferred technical solution for a plastic extrusion auxiliary machine, the plastic extrusion auxiliary machine includes multiple sets of moving mechanisms, which are spaced apart and mounted on the bottom surface of the main body.
[0018] The beneficial effects of this utility model are as follows:
[0019] This utility model provides a plastic extrusion auxiliary machine, including a main body and a moving mechanism. The moving mechanism is located on the bottom surface of the main body and enables the main body to move. The moving mechanism includes a track, rollers, and a connector.

[0031] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0032] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0033] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0034] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0035] like Figures 1 to 4As shown in the diagram, this embodiment provides a plastic extrusion auxiliary machine, including a main body 1 and a moving mechanism 2. The moving mechanism 2 is located on the bottom surface of the main body 1, enabling the main body 1 to move. The moving mechanism 2 includes a track 21, rollers 22, and a connecting member 23. The track 21 is laid on the workbench surface, specifically the ground. The track 21 includes a guide portion, and the rollers 22 are provided with guide grooves 221. The guide portion is located within the guide grooves 221, allowing the rollers 22 to roll along the guide portion. The connecting member 23 connects the rollers 22 and the main body 1. When the rollers 22 rotate along the track 21, they can drive the main body 1 to move along the direction in which the track 21 is laid. Since the moving mechanism 2 moves the main body 1 through the track 21 and rollers 22, even if the rollers 22 and track 21 rust due to water vapor corrosion, the rollers 22 can still rotate smoothly along the track 21 without jamming. Compared with the existing moving method using guide rails and sliders, the moving method of track 21 and rollers 22 can ensure the smooth real-time movement of the plastic extrusion auxiliary machine, thus ensuring the processing quality of the insulation layer and outer sheath in the cable.
[0036] For example, the track 21 includes a base plate 212 and a triangular guide bar 211. The triangular guide bar 211 is fixedly mounted on the base plate 212, and the bent end of the triangular guide bar 211 serves as the guide portion. The roller 22 includes two guide surfaces 222, which are located on both sides of the guide groove 221 in the width direction, and the guide surfaces 222 are in contact with the sides of the triangular guide bar 211. Thus, when the roller 22 rotates along the triangular guide bar 211, the two sides of the triangular guide bar 211 can limit the roller 22, improving the stability of the roller 22 during its movement along the triangular guide bar 211, thereby improving the stability of the movement of the main body 1. On the other hand, the plastic extrusion auxiliary machine also heat-melts the insulating material or sheathing material. The main body 1 will expand due to heat during the heating of the insulating material or sheathing material. During the rotation of the roller 22, the two guide surfaces 222 are in contact with the two sides of the triangular guide bar 211, which can prevent the main body 1 from shifting after expansion, ensuring that the main body 1 can move smoothly along the track 21. Furthermore, the base plate 212 and the triangular guide bar 211 are integrally formed. This ensures a stable connection between the two, preventing the triangular guide bar 211 from becoming loose relative to the base plate 212 during the movement of the main body 1 along the triangular guide bar 211 driven by the roller 22, thus further improving the smoothness of the main body 1's movement. On the other hand, it also reduces the processing steps of the track 21 and improves the processing efficiency of the track 21. In this embodiment, the base plate 212 is fixed to the ground by multiple bolts.
[0037] For example, such as Figures 2 to 6As shown, the connecting member 23 includes a bearing 231, a connecting shaft 232, and a connecting frame 233. The roller 22 has a through hole 223, and the bearing 231 is placed inside the through hole 223. The connecting shaft 232 passes through the inner ring of the bearing 231. The connecting frame 233 connects the bottom surface of the main body 1 and the connecting shaft 232, thus enabling the roller 22 to rotate and drive the main body 1 to move. Simultaneously, the bearing 231 improves the smoothness of the roller 22's rotation, thereby improving the smoothness of the main body 1's movement. Further, the through hole 223 includes a first circular hole, a second circular hole, and a third circular hole that are interconnected. The first and third circular holes are located at opposite ends of the second circular hole, and the diameters of both the first and third circular holes are larger than the diameter of the second circular hole. Two bearings 231 are provided, located inside the first and third circular holes respectively. The two bearings 231 further improve the smoothness of the roller 22's rotation, thereby improving the smoothness and fluidity of the main body 1's movement. By placing the two bearings 231 in the first and third circular holes respectively, the layout of the two bearings 231 is made more reasonable, further improving the rationality of the design of the moving mechanism 2. Preferably, the diameter of the first circular hole is the same as the diameter of the third circular hole, so that the two bearings 231 have the same specifications, which makes it easier for workers to assemble them and further improves the rationality of the design of the moving mechanism 2.
[0038] For example, the connecting frame 233 includes a clearance opening 2331, with a portion of the roller 22 placed within the clearance opening 2331. The connecting shaft 232 passes through the roller 22 and the connecting frame 233. The connecting member 23 also includes a locking member 24, which is used to lock the connecting shaft 232 to the connecting frame 233 to prevent the connecting frame 233 from shaking or even falling off the connecting shaft 232. The bottom surface of the connecting frame 233 is connected to the main body 1. When the roller 22 moves along the triangular guide bar 211, it can drive the connecting shaft 232 to move, thereby driving the main body 1 to move through the connecting frame 233. In this embodiment, the locking component 24 is a nut. One end of the connecting shaft 232 has an external thread, and the other end has a protrusion. The protrusion fits against the side wall of the connecting frame 233. The nut has an internal thread, and the external and internal threads are screwed together to lock the connecting shaft 232 and the connecting frame 233 together, preventing the connecting frame 233 from shaking or even falling off the connecting shaft 232 when the roller 22 moves. In this embodiment, the connecting frame 233 and the main body 1 can be fixedly connected by bolts or by welding. No specific restrictions are placed on the connection method between the connecting frame 233 and the main body 1.
[0039] Furthermore, the connector 23 also includes a gasket 25, which is placed between the locking member 24 and the side wall of the connecting frame 233. The gasket 25 can prevent the locking member 24 from scratching the side wall of the connecting frame 233, thus ensuring the aesthetics of the plastic extrusion auxiliary machine.
[0040] Preferably, the connector 23 further includes a reinforcing plate 26, which is fixedly connected to the side wall of the connecting frame 233. Specifically, two reinforcing plates 26 are provided, and the two reinforcing plates 26 are fixedly connected to the two side walls of the connecting frame 233 respectively. The inclusion of the reinforcing plates 26 can improve the rigidity of the connecting frame 233, enabling the connecting frame 233 to more stably connect the main body 1 and the connecting shaft 232, and further improve the service life of the moving mechanism 2.
[0041] Preferably, the connector 23 further includes two bushings 27, each sleeved on the connecting shaft 232 and located on both sides of the roller 22. The two ends of the bushings 27 abut against the inner wall of the side plate of the connecting frame 233 and the inner ring of the bearing 231, respectively. Since the outer wall of the connecting frame 233 is equipped with a locking element 24 to limit its movement, the bushings 27 can always abut against the inner ring of the bearing 231, preventing the bearing 231 from shifting during the movement of the roller 22 and further improving the smoothness of the roller 22's rotation. Simultaneously, the bushings 27 and the locking element 24 together clamp and fix the connecting frame 233, further preventing the connecting frame 233 from shaking, improving the smoothness of the movement of the main body 1, and further enhancing the rationality of the design of the moving mechanism 2.
[0042] In this embodiment, the plastic extrusion auxiliary machine includes multiple sets of moving mechanisms 2, which are spaced apart and mounted on the bottom surface of the main body 1. The multiple sets of moving mechanisms 2 enable the main body 1 to move more smoothly, thereby further improving the processing quality of the insulation layer and the outer protective layer.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
