Description

Technical Field

[0001] This invention relates to the technical field of wire insulation testing for winders, specifically to a wire insulation testing machine for winders. Background Art

[0002] A wire winder is a product that can wind wires, pipes, and other linear objects onto a spool for easy organization and storage, avoiding tools being scattered all over the place and saving time and effort. It is also called a wire reel or tube reel. During the winding process of the wire, the wire winder has strict requirements on the insulation of its insulation layer, so the insulation needs to be tested during the winding process.

[0003] As disclosed in announcement number CN209872027U, a winding-type wire insulation layer testing device includes a chassis, a support block, and a winding drum. Anti-slip bases are installed at both ends of the bottom of the chassis. A support block is installed in the middle of the top of the chassis. A motor is installed at one end of the top of the support block, and a rotating shaft is installed at the output end of the motor. The bottom end of the rotating shaft is connected to the top of the support block. A winding drum is installed at one end of the top of the chassis. A winding shaft is installed in the middle of the inside of the winding drum, and a handle is installed in the middle of one side of the winding shaft. This invention achieves this by installing a fixed rod at the end of the chassis top away from the winding drum. A first clamp, a second clamp, and a third clamp are sequentially installed on the side of the fixed rod near the conductive tube. A fixed chuck is installed on one side of each of the first, second, and third clamps. This allows for the replacement of clamps, increasing testing efficiency. Furthermore, replacing the clamps enhances the functionality of the device and extends its service life.

[0004] As disclosed in announcement number CN117262885A, an anti-tangling winding machine for producing wires and cables is specifically related to the technical field of wire and cable production equipment. It includes a transmission mechanism, a support frame on one side of the upper end of the transmission mechanism, a limit device on the other side of the upper end of the transmission mechanism, a cylinder at the upper end of the support frame, a transmission device at the output end of the cylinder, a conveyor belt wound around the middle of the outer surface of the transmission mechanism, and winding devices arrayed on the outer surface of the conveyor belt. This anti-tangling winding machine for producing wires and cables, by setting a limit mechanism, after the wires and cables are wound, the L-shaped rods activate the limit mechanism, causing four support rods to drive four fixing plates to contact the surface of the wound wires and cables, thus fixing the wound wires and cables and preventing them from loosening, thereby improving the stability of the device.

[0005] However, existing wire insulation testing machines for winding devices still have the following shortcomings:

[0006] 1. In the actual winding process, it is inconvenient to quickly disassemble and assemble the winding roller, and it is also inconvenient to replace the test roller after winding. Moreover, the display effect of the insulation test results is not obvious enough, and there is a lack of warning and alarm devices to remind when abnormalities are detected.

[0007] 2. When the wound wire is being wound, it tends to accumulate on the winding roller, making it difficult to wind evenly on the winding roller, which will affect the actual test results.

[0008] 3. Before testing, the outer surface of the wire may have some dirt, which is inconvenient to wipe off. In addition, the stability of the wire is not good during winding and testing.

[0009] Therefore, we propose a wire insulation testing machine for winding devices to solve the problems mentioned above. Summary of the Invention

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] See also Figures 1-14 The present invention provides the following technical solution:

[0051] Example 1: To address the problems in the existing technology, such as the inconvenience of quickly disassembling and assembling the winding roller, the cumbersome replacement of the detection roller 4 after winding, the insufficient display of insulation test results, and the lack of warning and alarm devices when abnormalities are detected, this example provides a winding wire insulation testing machine, comprising a base 1, a front side plate 2, a rear side plate 3, a detection roller 4, an outer metal layer 5, a fixing rod 6, a fixing bracket 7, a reduction motor 8, a connecting cylinder 9, a mounting mechanism 10, a movable column 14, a fixed column 15, a fixing block 16, and a spring 17. The base includes a positioning plate 18, an alarm 33, and a fault indicator light 34. A detection roller 4 is located in the middle of the upper left side of the base 1, and the outer surface of the detection roller 4 is covered with an outer metal layer 5. An alarm 33 is fixedly installed in the middle of the left side of the base 1, and fault indicator lights 34 are located on both the front and rear sides of the alarm 33. A mounting mechanism 10 is located on the rear side of the upper end of the rear side plate 3, and the mounting mechanism 10 drives the detection roller 4 to form a disassembly structure between the front side plate 2 and the rear side plate 3. The mounting mechanism 10 consists of a connecting bracket 11, a movable plate 12, and a movable sleeve 13. Fixed rods 6 are fixedly connected to both the front and rear ends of the detection roller 4, and the outer surface of the fixed rods 6... A convex key for positioning is provided. The front fixing rod 6 is inserted into the connecting cylinder 9 and is engaged with the upper end of the front side plate 2. The connecting cylinder 9 is fixedly connected to the output end of the reduction motor 8, and the reduction motor 8 is fixedly installed at the front end of the fixed bracket 7. The fixed bracket 7 is fixedly connected to the front side of the upper end of the front side plate 2. The upper end of the rear side plate 3 is engaged with the rear fixing rod 6. The rear fixing rod 6 is inserted into the middle of the movable sleeve 13. The movable sleeve 13 is rotatably installed on the upper end of the movable plate 12, and the lower end of the movable plate 12 and the connecting bracket 11 form a front-to-back sliding structure. The connecting bracket 11 is fixedly connected to the rear side plate 2. On the rear side of the upper end of plate 3, and the connection between the bracket 11 and the movable plate 12 is limited by the positioning plate 18. Both the front and rear ends of the positioning plate 18 are engaged in the fixing holes at corresponding positions. The fixing holes are opened at the upper end of the connecting bracket 11. A fixing post 15 is fixedly connected to the middle of the positioning plate 18, and the middle of the fixing post 15 and the movable post 14 form an up-and-down sliding structure. The movable post 14 is fixedly connected to the rear end of the movable plate 12, and a fixing block 16 is fixedly connected to the rear end of the movable post 14. The fixing block 16 and the fixing post 15 form an up-and-down sliding structure, and a spring 17 is provided between the fixing post 15 and the movable post 14. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, firstly, the detection roller 4 is placed between the front side plate 2 and the rear side plate 3. The detection roller 4 drives the fixing rod 6 to engage with the upper ends of the front side plate 2 and the rear side plate 3 respectively. Then, the detection roller 4 is moved forward, so that the detection roller 4 drives the front fixing rod 6 to insert into the connecting cylinder 9. Then, the movable column 14 is pulled upward, and the movable column 14 slides between the fixed column 15 and the fixing block 16. The movable column 14 compresses the spring 17, causing the spring 17 to undergo elastic deformation. At this time, the movable column 14 drives the positioning plate 18 to disengage from the fixing hole on the connecting bracket 11, thereby releasing the limit between the movable plate 12 and the connecting bracket 11. Then, the movable plate 12 is pulled forward, and the movable plate 12 slides between the connecting bracket 11. At this time, the detection roller 4... The rear fixing rod 6 is inserted into the movable sleeve 13, and then the movable column 14 is released directly. At this time, the spring 17 returns to its elastic deformation, causing the movable column 14 to push the positioning plate 18 downward and insert it into the fixing hole at the corresponding position. This limits the connection between the connecting bracket 11 and the movable plate 12. Through the above operation, it is convenient to install and position the detection roller 4. Moreover, after use, the detection roller 4 can be disassembled and replaced by reversing the above operation. Start the reduction motor 8 to drive the connecting cylinder 9 to rotate slowly. At this time, the connecting cylinder 9 drives the detection roller 4 to rotate through the front fixing rod 6 to perform winding detection on the wire. At the same time, the detection roller 4, together with the rear fixing rod 6, drives the movable sleeve 13 to rotate in the middle of the movable plate 12.

[0052] In addition, during the testing process, the outer metal layer 5 is connected to an external power source for power supply. At the same time, the outer metal layer 5 is electrically connected to the fault indicator light 34 and the alarm 33. The wire being tested is wound around the outer metal layer 5 on the outside of the testing roller 4. When the non-insulated part of the wire can connect and conduct electricity with the outer metal layer 5 during testing, the central processing unit controls the alarm 33 and the fault indicator light 34 to be turned on. The alarm 33 will sound an alarm, and the fault indicator light 34 will flash to raise the attention of the testing personnel.

[0053] Example 2: To address the problem in existing technologies where wound wires tend to accumulate on the winding roller during winding, hindering even winding and affecting actual test results, this example provides a wire insulation testing machine for a winding device. The machine includes a moving mechanism comprised of a support plate 19, a servo motor 20, a gear 21, a movable crossbar 22, and a support rail 23. A connecting mechanism 24 is located at the upper left end of the moving mechanism, driving the connecting mechanism 24 to reciprocate back and forth on the upper end of the base 1. The support plate 19 is fixedly connected to the upper right end of the base 1, and a servo motor 20 is fixedly mounted on the upper end of the support plate 19. The output end of the servo motor 20 is fixedly connected to the gear 21, which drives the gear 21 to rotate on the right end of the base 1. The left side of the gear 21 is meshed with the movable crossbar 22, and the middle of the movable crossbar 22 and the support rail 23 form a sliding structure. The support rail 23 is fixedly connected to the upper end of the base 1. Figure 1 , Figure 2 and Figure 11 As shown, during the winding process, the servo motor 20 can be started to slowly rotate forward and backward. The servo motor 20 drives the gear 21 to rotate, so that the gear 21 drives the movable crossbar 22 to form a front-to-back sliding structure with the support rail 23. At this time, the moving plate 25 drives the wire to move back and forth, so that the wire can be more evenly distributed on the detection roller 4, preventing the wire from accumulating on the detection roller 4.

[0054] Example 3: To address the problems in the prior art where the outer surface of the wire may have some dirt before testing, making it inconvenient to wipe and remove the dirt, and the wire's stability is poor during winding and testing, this example provides a wire insulation testing machine for a winding device. The machine includes a connecting mechanism 24, a lower auxiliary plate 29, a movable rod 30, a stop rod 31, and an upper auxiliary plate 32. The connecting mechanism 24 consists of a movable plate 25, a lower arc plate 26, an upper arc plate 27, and a cleaning cloth 28. The upper arc plate 27 forms a flipping structure above the lower arc plate 26. Cleaning cloths 28 are provided on the inner sides of both the upper and lower arc plates 27 and 26. The left end of the movable crossbar 22 is fixedly connected... A vertically oriented movable plate 25 is connected to a lower arc plate 26, the upper end of which is hinged to an upper arc plate 27. A lower auxiliary plate 29 is fixedly connected to the rear end of the lower arc plate 26, and an upper auxiliary plate 32 is fixedly connected to the rear end of the upper arc plate 27. A movable rod 30 is rotatably connected to the middle of the lower auxiliary plate 29, and a torsion spring is provided at the connection between the movable rod 30 and the lower auxiliary plate 29. The rotation angle between the movable rod 30 and the lower auxiliary plate 29 ranges from 0 to 90°. A stop rod 31 is fixedly connected to the upper end of the movable rod 30, and the stop rod 31 is fitted against the upper end of the upper auxiliary plate 32. The length of the stop rod 31 is smaller than the length of the slot in the upper auxiliary plate 32. Figure 1 , Figure 2 , Figure 12 , Figure 13 and Figure 14 As shown, before the wire is inspected and rewound, the wire to be inspected is placed in the middle of the lower arc plate 26. Then, by rotating the movable rod 30 to 90°, the movable rod 30 rotates in the middle of the lower auxiliary plate 29. At this time, the torsion spring undergoes elastic deformation, and the movable rod 30 drives the stop rod 31 to rotate. Then, the upper arc plate 27 is flipped downwards and locked onto the upper end of the lower arc plate 26. At the same time, the stop rod 31 passes through the slot in the middle of the upper auxiliary plate 32. Then, the movable rod 30 is released, the torsion spring returns to its elastic deformation, and the movable rod 30 rotates. At this time, the stop rod 31 is fitted against the upper end of the upper auxiliary plate 32, limiting the movement between the lower arc plate 26 and the upper arc plate 27. The wire and the cleaning cloth 28 are fitted together. Through the friction between the wire and the cleaning cloth 28, the dirt on the wire can be wiped away. Moreover, the clamping of the wire by the lower arc plate 26 and the upper arc plate 27 can improve the stability of the wire during movement.
