Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to an automatic expansion machine for insulating tubes with automatic feeding. Background Technology

[0002] An automatic insulation tube expander is a specialized piece of equipment used in wire and cable production and related applications. It mechanically expands insulation tubes, precisely enlarging those with smaller inner diameters to the appropriate size, allowing the wire core to be placed smoothly. This provides effective insulation protection for the wire core, preventing electrical safety issues such as leakage, and ensures the overall structural stability and reliable performance of the wire and cable during subsequent use and installation. It also guarantees the safe and orderly operation of power transmission and related work. During insulation tube expansion, several insulation tubes are often placed together... Next to the automatic insulation tube expander, these tubes are usually placed rather haphazardly, scattered in a disorganized state. Subsequently, the operator will expand these insulation tubes one by one according to the corresponding operating procedures. The random placement of the insulation tubes can easily lead to a messy and disorderly work site, making it difficult for the operator to quickly and accurately pick up the insulation tubes, which will reduce work efficiency. Moreover, the random scattering of insulation tubes may cause their surfaces to be contaminated with dust, impurities and other foreign objects. During subsequent expansion and use, these impurities may enter the interior of the insulation tube or adhere to the tube wall, affecting the quality of the insulation tube, reducing its insulation performance, and may even pose potential safety hazards to the wire cores to be wrapped later.

Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1

[0028] Reference Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides an automatic expansion machine for insulating tubes with automatic feeding. The automatic expansion machine for insulating tubes with automatic feeding includes a main body component 100 and a feeding component 200. The two work together to neatly place several insulating tubes in a storage box and then automatically feed them, which is convenient to pick up and improves the efficiency and ease of operation of the expansion of insulating tubes.

[0029] The main component 100 includes an expansion machine body 101, a switch 102 fixed on one side of the expansion machine body 101, and a receiving box 103 fixed on one side of the expansion machine body 101.

[0030] Four expansion bars are typically provided on the expansion machine body 101. By placing the insulating tube on the four expansion bars and then activating the switch 102, the four expansion bars move synchronously towards each other to complete the expansion of the insulating tube. Then, the wire core is placed inside the insulating tube, and the four expansion bars are returned to their original positions. At this time, the wire core can be fixed inside the insulating tube by the spring-loaded contraction due to the characteristics of the insulating tube. After wrapping, the insulating tube is removed from the expansion bars and placed in the receiving box 103 for storage. When the expansion bars move, the next insulating tube can be discharged to facilitate the next expansion.

[0031] The feeding assembly 200 is disposed on the expansion machine body 101 and includes a feeding component 201. The feeding component 201 includes a feeding roller 2011. A guide plate 2012 is disposed on one side of the feeding roller 2011, and a storage box 2013 is disposed above the guide plate 2012.

[0032] Multiple slots are provided on the feeding roller 2011. When adding insulating tubes into the storage box 2013, the cylindrical insulating tubes can be guided into the slots by the guide plate 2012. At this time, the feeding roller 2011 rotates by the movement of the expansion bar. When the slots on the feeding roller 2011 rotate to the bottom, the insulating tubes inside can fall out for easy access by the operator. Before use, the expansion bar can be moved several times in advance to fill the slots with insulating tubes.

[0033] Example 2

[0034] Reference Figures 2-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, the feeding assembly 200 also includes a support member 202, which includes a support box 2021. The support box 2021 is sleeved on the outside of the feeding roller 2011, and the support box 2021 and the feeding roller 2011 are rotatably connected by a rotating shaft.

[0036] The guide plate 2012 is fixed to the inner wall of the support box 2021. The support box 2021 can support the guide plate 2012 and the feeding roller 2011 to prevent them from shifting.

[0037] Specifically, a positioning frame 2022 is fixed to the bottom of the support box 2021, and a slide 2023 is fixed to the bottom of the positioning frame 2022. The slide 2023 is set as an inclined surface.

[0038] When the insulating tube falls from the trough, it can fall onto the slide 2023, and then fall outside through the guide of the inclined slide 2023 for easy retrieval. The positioning frame 2022 can support the slide 2023.

[0039] Specifically, a sloping panel 2024 is fixed to the inner wall of the storage box 2013, and a placement frame 2025 is fixed to the top of the storage box 2013.

[0040] The insulating tube is placed laterally from the placement frame 2025 into the storage box 2013, and then guided by the inclined panel 2024 to the slot on the feeding roller 2011.

[0041] Specifically, the feeding assembly 200 also includes a movable part 203, which includes a rotating block 2031. The rotating block 2031 is fixed to one side of the feeding roller 2011, and a drive rod 2032 is hinged to the bottom of the rotating block 2031.

[0042] The rotating block 2031 is set at an angle. When the expansion bar moves to expand, it can drive the drive rod 2032 to move. At this time, the movement of the drive rod 2032 can drive the rotating block 2031 to rotate. Then, when the expansion bar returns to its original position to retract, it can drive the drive rod 2032 to return to its original position. Since the rotating block 2031 is set at an angle, the drive rod 2032 can make the rotating block 2031 rotate when it moves, thereby making the feeding roller 2011 rotate.

[0043] Specifically, a connecting plate 2033 is fixed to one side of the drive rod 2032, and a spring 2034 is fixed to the bottom of the connecting plate 2033. One end of the spring 2034 is fixed to the top of the expander body 101.

[0044] When the drive rod 2032 moves, it can drive the connecting plate 2033 to move. The movement of the connecting plate 2033 can apply a pulling force to the spring 2034. Then, when the expansion bar returns to its original position and contracts, the rebound force of the spring 2034 can make the drive rod 2032 return to its original position.

[0045] Specifically, a support frame 2035 is fitted on the outer side of the drive rod 2032, and the support frame 2035 and the drive rod 2032 are movably connected.

[0046] The support frame 2035 is fixed to the top of the expansion machine body 101, and the support box 2021 is fixed to one side of the support frame 2035. The support box 2021 can be supported by the support frame 2035.

[0047] Example 3

[0048] Reference Figures 1-4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0049] Specifically, a cam 2036 is provided at the bottom of the drive rod 2032, and a rotating rod 2037 is inserted into one side of the cam 2036.

[0050] The rotation of the rotating rod 2037 can drive the cam 2036 to rotate. At this time, the cam 2036's convex surface presses against the drive rod 2032, thereby causing the drive rod 2032 to move. When it is necessary to return the expansion bar to its original position and retract, the rotating rod 2037 rotates, which at the same time drives the cam 2036 to rotate, releasing the pressure on the drive rod 2032 and allowing the drive rod 2032 to return to its original position.

[0051] Specifically, the feeding assembly 200 also includes a rotating component 204, which includes a turntable 2041. The turntable 2041 is fixed to one end of the drive rod 2032, and an expansion column 2042 is provided on one side of the turntable 2041.

[0052] A drive groove corresponding to the expansion column 2042 is provided on the turntable 2041. The turntable 2041 is rotatably connected to the inner wall of the expander body 101 through a bearing. The expansion column 2042 is fixed to one end of the expansion bar. A sliding groove corresponding to the expansion bar is provided on the expander body 101. The expansion bar slides in the sliding groove, and the expansion column 2042 slides in the drive groove. When it is necessary to expand the expansion bar to open the insulating tube, the rotation of the rotating rod 2037 will drive the turntable 2041 to rotate. At this time, the rotation of the turntable 2041 can drive the drive groove to squeeze the expansion column 2042 and make it move. Then, the movement of the expansion column 2042 can drive the expansion bar to move, thereby expanding and opening the insulating tube.

[0053] Specifically, a motor 2043 is fixed to one end of the drive rod 2032, and the motor 2043 is fixed to the inner wall of the expander body 101.

[0054] The motor 2043 can drive the rotating rod 2037 to rotate.

[0055] In use, the insulating tube is first placed horizontally from the placement frame 2025 into the storage box 2013. Then, the insulating tube is guided by the inclined panel 2024 to the guide plate 2012. The cylindrical insulating tube can be guided by the guide plate 2012 to the slot. By starting the motor 2043 several times to make the feeding roller 2011 rotate, the slot containing the insulating tube will move to the top of the slide 2023.

[0056] At this point, pressing switch 102 again starts motor 2043. Pressing switch 102 to rotate motor 2043 is existing technology and common knowledge to those skilled in the art, so it will not be elaborated upon here. When motor 2043 rotates, it first drives rotating rod 2037 to rotate. The rotation of rotating rod 2037 drives turntable 2041 to rotate. The rotation of turntable 2041 then drives the drive groove to press against expansion column 2042, causing it to move. Then, the movement of expansion column 2042... The expansion bar moves, thus expanding and opening the insulating tube. Simultaneously, the rotation of the rotating rod 2037 drives the cam 2036 to rotate. The cam 2036's convex surface presses against the drive rod 2032, causing it to move. This movement of the drive rod 2032 moves the connecting plate 2033, which in turn applies a pulling force to the spring 2034. The movement of the drive rod 2032 causes the rotating block 2031 to rotate, thus rotating the feeding roller 2011. Move the motor 2043 half a turn to open the insulating tube and place the wire core inside. Then, restart the motor 2043 to rotate it in the opposite direction. This causes the rotating rod 2037 to rotate in the opposite direction, driving the turntable 2041 to rotate in reverse. This allows the expansion bar to return to its original position and contract. Through the springback contraction characteristic of the insulating tube, the wire core can be fixed inside the insulating tube. At the same time, the reverse rotation of the rotating rod 2037 causes the cam 2036 to rotate in the opposite direction, releasing the pressure on the drive rod 2032. The springback force of the spring 2034 allows the drive rod 2032 to return to its original position. This allows the rotating block 2031 to rotate, which in turn causes the feeding roller 2011 to rotate half a turn again. Then, the slot on the feeding roller 2011 rotates downward, and the insulating tube inside can fall onto the slide rail 2023. Then, guided by the inclined slide rail 2023, it can fall outside, making it easy for the operator to pick up. Then, the insulating tube is removed from the expansion bar and placed in the receiving box 103 for storage. The newly discharged insulating tube can then be put back onto the expansion bar. By repeating this process, the insulating tube can be automatically fed during expansion.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
