Description

Technical Field

[0001] This utility model relates to the field of edge curling fixture technology, specifically an edge curling retraction device. Background Technology

[0002] The structure of shielded installation wire is relatively complex. It adds a layer of silver-plated copper braided mesh to the insulation layer of ordinary installation wire. Usually, when processing the ends, it is necessary to use tools such as an electrician's knife to cut the silver-plated copper braided mesh to separate the core wire from the shielding layer. Safety precautions must be taken during this process. Alternatively, the open-pull method can be used. Near the end, use tweezers to pry open the shielding braided mesh, pull out the core wire from the opening in the shielding braided mesh, and stretch it outwards to separate the core wire from the shielding layer.

[0003] The disadvantages of the original manual operation are: (1) Due to the limitations of the tools used, there are many auxiliary actions: When using tools such as electrician's knife to directly cut the silver-plated copper braided mesh, care should be taken to avoid injury to the fingers holding the shielded installation wire, and the force should be appropriate so as not to damage the core wire; when using tweezers to take the opening extraction method, the shielded braided mesh needs to be pulled multiple times so that the opening is large enough to accommodate two core wires, and then the core wires can be extracted segment by segment. (2) Due to the differences in each person's technique and force, the length of the extracted core wire is different, and the effect of rubbing the shielded braided mesh is also different, so the appearance of the processed end is often different from person to person. (3) When processing shielded installation wires of different diameters, although the manual operation process is the same, the operator needs some time to adapt to the change in feel because of the change in the required force. (4) Long-term monotonous operation will cause the operator's movements to become deformed, resulting in accidental losses. (5) When manually processing the end of the shielded installation wire, the wires are usually cut off according to the required quantity first, and then the end is processed in a concentrated manner. Individuals cannot carry out assembly line operations.

[0004] To address the aforementioned issues, an innovative design was developed based on the existing equipment for drying and fermenting black tea. Utility Model Content

[0005] The purpose of this utility model is to provide a curling and retracting device to solve the problems mentioned in the background art above: (1) Due to the limitations of the tools used, there are many auxiliary actions: When using tools such as electrician's knife to directly cut the silver-plated copper braided mesh, care should be taken to avoid injury to the fingers holding the shielded installation wire, and the force should be appropriate so as not to damage the core wire; when using tweezers to take the opening extraction method, the shielded braided mesh needs to be scratched many times so that the opening is large enough to accommodate two core wires, and then the core wires can be extracted segment by segment. (2) Due to the differences in each person's technique and force, the length of the extracted core wire is different, and the effect of rubbing the shielded braided mesh is also different. The appearance of the processed end is often different from person to person. (3) When processing shielded installation wires of different diameters, although the manual operation process is the same, the operator needs some time to adapt to the change in feel because the required force varies. (4) When performing a single and monotonous operation for a long time, the operator's movements will become deformed, resulting in accidental losses. (5) When manually processing the end of the shielded installation wire, the wires are usually cut off according to the required quantity first, and then the end is processed in a concentrated manner. Individuals cannot carry out assembly line operations.

A sliding bracket 16 is provided on the base plate 1, and the sliding bracket 16 is fixed to the base plate 1 by screws 2. The screws 2 ensure a firm connection between the cams 3 and the cam brackets 5 on the base plate 1, and the sliding bracket 16 ensures the fixing of the shielded installation line.

[0020] A support plate 25 is provided on the base plate 1. The cam frame plate 5, the support plate 25 and the slide plate 16 are fixed to the base plate 1 by screws 2. The support plate 25 provides a guarantee for the movable connection of the cam frame plate 5 and the slide plate 16.

[0021] A connecting rod 6 is provided on the base plate 1. One end of the connecting rod 6 is movably inserted through the through hole on the cam 3. The connecting rod 6 is used to connect the cam 3 and the tapered clamp adjustment support 7.

[0022] The base plate 1 is provided with a left conical clamp 13 and a right conical clamp 14. The left conical clamp 13 is riveted to the right conical clamp 14. A conical clamp spring 10 is movably connected between the left conical clamp 13 and the right conical clamp 14. The conical clamp spring 10 is movably connected to the conical clamp seat 8. A conical clamp cover plate 9 is sleeved on the conical clamp spring 10. A conical clamping rod 11 is movably connected to the conical clamp spring 10. The left conical clamp 13 and the right conical clamp 14 provide protection for squeezing open the shielding braided mesh and clamping the core of the shielding installation wire. The conical clamp spring 10 and the conical clamping rod 11 are used in cooperation.

[0023] The conical clamp holder 8 is movably installed inside the conical clamp adjustment support 7; the setting of the conical clamp adjustment support 7 provides a guarantee for the movable adjustment of the conical clamp holder 8.

[0024] The base plate 1 is provided with a sliding rod 24 and a spring 19. The sliding rod 24 and the spring 19 are movably installed in the sliding groove of the limiting plate 18. The base plate 1 is provided with a connecting rod 21. The connecting rod 21 is movably connected to the through hole at the top of the sliding rod 24. The connecting rod 21 is threadedly connected to the handle rod 17. The handle rod 17 is movably fitted with an adjusting nut 15. The handle rod 17 is connected to a positioning pin 20. The spring 19 provides a guarantee for the sliding of the sliding rod 24. The limiting plate 18 plays a limiting role. The positioning pin 20 is used to fix the handle rod 17.

[0025] Working principle: According to Figure 1-2First, clean all parts of the edge retraction device and prepare the shielded installation wire for the tap. Move the cam 3 wheel rim away from the support plate 25 to facilitate the shielded installation wire passing through the wire groove on the support plate 25. Then, pull the shielded installation wire through the wire notch in the slide plate 16 to the outlet hole of the limit plate 18. The sliding rod 24 slides towards the outlet hole under the combined action of the spring 19 and gravity. The symmetrical arc of the sliding rod 24 squeezes the shielded installation wire. The handle 17 drives the sliding rod 24 to slide to the left several times, causing the shielded braided mesh at the end of the shielded installation wire to bulge. This presses down the conical clamping rod 11 several times, causing the left conical clamp 13 and right conical clamp 14 to squeeze open the shielded braided mesh and clamp the core of the shielded installation wire. Tighten the adjusting nut 15 and fasten it to the locking notch in the slide plate 16. When the symmetrical arc of the sliding rod 24 presses the outer edge of the shielding braided mesh onto the sliding bracket plate 16, the core of the shielding installation wire is not tightened by the symmetrical arc of the sliding rod 24. Rotating the left conical clamp 13 and the right conical clamp 14 to the left pulls out the core of the shielding installation wire. The adjusting nut 15 is disengaged from the notch of the sliding bracket plate 16, and the shielding installation wire completed in one tap is led out from the outlet hole of the limiting plate 18. The shielding installation wire is cut to the required length, and the next tapping operation is continued. When the specifications of the shielding installation wire change and the tapping operation is incomplete, the adjustment is made by adjusting the support 7 of the conical clamp and the adjusting nut 15. The above is the working process of the entire device. All contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
