Description

TECHNICAL FIELD

[0001] The utility model belongs to wire production technical field, more specifically, it relates to a wire take-up and pay-off grounding device. BACKGROUND

[0002] During the irradiation crosslinking processing of the electric wire, a large number of free electrons are gathered in the internal conductor when the electric wire passes through the electron beam, if the conductor of the electric wire is not grounded or is poorly grounded, a large number of electrons will not be released, and when the human body contacts the electric wire, electric shock phenomenon will occur. Generally, during the irradiation crosslinking processing of the electric wire, the wire reel is used for taking up and paying off the wire. The main consideration is that the grounding of the wire head and the wire tail must be stopped during the production of the wire reel, and the more the number of stoppages, the lower the effective operation time. The large-capacity wire reel can reduce the number of stoppages as much as possible. The use of large-capacity wire reels reduces the frequency of jointing and stopping, but there are still some problems in reality. For example, when irradiating high-temperature automobile wire, the customer requires a 300-type plastic reel for delivery, and the reel length is generally several kilometers. If a 630-type or larger reel is used for taking up and paying off, the reel capacity increases, and the jointing and stopping are obviously reduced, but a rewinding and dividing process is added after irradiation. If a 300-type reel is used for taking up and paying off directly, since the irradiation speed of the wire is generally several hundred meters per minute, the interval time for changing the reel is only a few minutes, so the frequency of changing the reel increases, and the grounding frequency increases. Under the above-described working conditions, even if there is a wire storage rack with a capacity of about 300 meters to buffer, the reel must be changed within one minute, otherwise the irradiation wire will automatically stop if the wire length exceeds the storage length. When using a double-reel taking-up method, the work to be completed in one minute includes cutting the wire, threading the wire, and grounding the wire head. If the traditional stripping and winding method is used, since the free electrons gathered in the conductor of the electric wire have the risk of discharge, the operator needs to wear insulating gloves to operate, which inevitably affects the flexibility of operation and prolongs the grounding operation time. One minute or so is often not enough, and the operator is under mental stress and fatigue, which may lead to safety accidents. Similar to the above-mentioned high-temperature automobile wire irradiation production problems, using a large-capacity reel for taking up and paying off increases the rewinding and dividing process after irradiation, and increases the labor cost. If the delivery reel is used for taking up and paying off, the grounding problem must be solved to ensure the operation of the production line and improve the safety risk of operation.

DETAILED DESCRIPTION

[0025] The shape, structure, mutual position and connecting relationship between the parts, the function and working principle of each part of the specific embodiment of the utility model will be further described in detail by the description of the embodiment with reference to the drawings:

[0026] As shown in the drawing, Figure 1 - the drawing, Figure 5 The utility model discloses an electric wire winding and grounding device, and the grounding device 1 (a broken skin grounding device) is installed on the wire disc 4. The grounding device 1 comprises a sleeve 8 and a sleeve rod 9. The sleeve 8 is a hollow structure. The outer ring of the sleeve rod 9 is provided with a recessed groove 92. The threading hole 91 penetrates the groove 92. The through hole 81 penetrating the sleeve 8 is arranged on the sleeve 8. The above structure improves the technical scheme according to the defects in the prior art. When the grounding device 1 (the broken skin grounding device) is installed on the wire disc 4, the electric wire can pass through and the broken skin operation can be conveniently realized. The sleeve rod 9 is screw-connected with the sleeve 8. When the broken skin grounding is performed, the end of the cut electric wire 3 passes through the electric wire passing hole 10 of the side plate of the wire disc 4, the through hole 81 of the sleeve 8 and the threading hole 91 of the sleeve rod 9, and the end of the electric wire 3 slightly protrudes from the outside of the sleeve 8. Because the sleeve 8 is a fixed structure, when the sleeve rod 9 rotates, the sleeve rod 9 rotates relative to the sleeve 8, so that the electric wire 3 at the joint part is extruded through the cooperation of the groove 92, the threading hole 91 and the inner wall of the sleeve 8, the insulating layer of the electric wire 3 is broken, the internal conductor of the electric wire 3 contacts the metal part of the grounding device 1, the metal part of the grounding device 1 is conductive with the grounding main line, and the grounding of the electric wire 3 is realized. In this way, the grounding operation of the electric wire is extremely convenient and fast, and the grounding operation can be completed in a very short time, that is, the grounding operation can be completed in one minute, so that the electric wire grounding can be completed in the interval time, the irradiation equipment does not need to be slowed down or stopped, and the production efficiency is effectively improved. The electric wire winding and grounding device has the advantages of simple structure and the ability to complete the broken skin connection of the electric wire in a very short time, does not need to slow down or stop the irradiation equipment, and does not affect the production efficiency.

[0027] The inner wall of the sleeve 8 is a threaded structure, and the outer ring of the sleeve rod 9 is a threaded structure. The sleeve rod 9 and the sleeve 8 can be screw-connected, and the two can be conveniently and flexibly rotated.

[0028] An insulated handle 5 is connected to the upper end of the sleeve rod 9. With this structure, the insulated handle 5 allows the operator to rotate the sleeve rod relative to the sleeve without wearing insulated gloves, thus ensuring operational safety while effectively achieving operational flexibility.

[0029] The upper retaining spring 61 is fitted into the upper retaining spring groove near the upper end of the sleeve rod 9, and the lower retaining spring 62 is fitted into the lower retaining spring groove near the lower end of the sleeve rod 9. In the above structure, retaining spring grooves (retaining spring grooves) are provided at both the upper and lower ends of the sleeve rod 9 for installing retaining springs. After the upper and lower retaining springs are installed, the distance between them is greater than the height of the sleeve base, which realizes the limitation of the vertical movement of the sleeve rod, and allows it to rotate flexibly.

[0030] The wire reel 4 is mounted on the spool 2, and a wire through hole 10 is provided on the side of the wire reel 4. In this structure, when the wire is grounded, the end passes through the wire through hole and extends into the grounding device.

[0031] The pitch P of the thread structure on the outer ring of the sleeve rod 9 is selected to be approximately one time the outer diameter of the smallest specification wire 3, and is an integer multiple of 0.5. Specific embodiments of the above structure are illustrated below: For example, high-temperature automotive wiring harnesses typically have a cross-section of 0.35mm²-6mm², resulting in an outer diameter of 1.4mm-5mm; for grounding devices 1 used in products within this range, the pitch P is an integer multiple of 0.5, specifically 1.5mm.

[0032] The groove 92 is an arc-shaped groove. The width W of the groove 92 is 1.5-2.0 times the outer diameter of the largest specification wire 3, and is an even integer multiple of the pitch P. The bottom depth H of the groove 92 is set to 0.7-0.9 times the outer diameter of the smallest specification wire 3. Specific embodiments of the above structure are illustrated below: For example, high-temperature automotive wiring harnesses typically have a cross-section of 0.35mm²-6mm² and an outer diameter of 1.4mm-5mm. For the grounding device 1 used in products within this range, the arc-shaped groove width W is selected as 6P=9mm, and the bottom depth H is selected as 1-1.25mm. The diameter of the wire hole 91 is selected as 1.1-1.3 times the outer diameter of the largest specification wire 3, allowing the device to accommodate various wire specifications.

[0033] A washer 7 is fitted between the upper retaining spring 61 and the upper end of the sleeve rod 9, and a washer 7 is fitted between the lower retaining spring 62 and the lower end of the sleeve rod 9. The rotation angle of the insulating handle 5 is controlled within the range of 70°-100°. With the above structure, the sleeve rod 9 can be rotated flexibly and conveniently via the insulating handle 5.

[0034] The procedure for grounding wires using the device of this utility model is as follows: 1) Install the wire reel 4: The wire reel 4 is installed on the spool 2; 2) Thread the wire: The cut wire 3 is threaded sequentially through the wire through hole 10 on the side plate of the wire reel 4, the through hole 81 on the sleeve 8, and the thread hole 91 on the sleeve rod 9, with the end of the wire 3 slightly protruding outside the grounding device 1; 3) Grounding: Rotate the insulating handle 5, and through the groove of the sleeve rod and the threaded structure of the sleeve, the wire 3 located inside the grounding component is squeezed, the insulation layer of the wire 3 is broken, and the conductor inside the wire 3 is connected to the grounding main line through the metal part of the grounding device, thus achieving grounding of the wire 3; 4) Start the drive motor to drive the spool 2 to rotate, and start the winding of the wire 3 into a reel until the preset length is reached and the machine automatically stops; 5) Install wire reels on both sides of the spool. While the wire 3 is being wound into a reel on one side of the spool 2, the wire 3 on the other side of the spool 2 can be wound into a reel, completing the disassembly of the full wire reel 4 and the installation preparation of the empty wire reel 4, waiting for the reel to be replaced. The above steps are repeated. When the wire 3 switches between the two wire reels 4, the operation takes no more than one minute. It does not require the irradiation equipment to slow down or stop, so it does not affect production efficiency and meets actual needs.

[0035] The wire retraction and grounding device of this utility model is structurally designed such that the grounding device 1 (insulation breaking grounding device) is installed on the wire reel 4, facilitating the passage of the wire and the insulation breaking operation. The sleeve rod 9 is screwed to the sleeve base 8. When performing insulation breaking grounding, the cut end of the wire 3 is passed through the wire through hole 10 on the side plate of the wire reel 4, the through hole 81 on the sleeve base 8, and the wire through hole 91 on the sleeve rod 9, with the end of the wire 3 slightly protruding from the outside of the sleeve base 8. Because the sleeve base 8 is a fixed structure, when the sleeve rod 9 is rotated, the sleeve rod 9 rotates relative to the sleeve base 8, thereby squeezing the wire 3 at the joint through the groove 92, the wire through hole 91, and the inner wall of the sleeve base 8, causing the insulation layer of the wire 3 to break. The internal conductor of the wire 3 contacts the metal part of the grounding device 1, and the metal part of the grounding device 1 is connected to the grounding main line, thus achieving grounding of the wire 3. In this way, the grounding operation of the wire is extremely convenient and quick, and can be completed in a very short time, within one minute. This allows for effective use of the gap time to complete the grounding of the wire, without the need for the irradiation equipment to slow down or stop, thus effectively improving production efficiency.
