Description

Technical Field

[0001] This invention relates to the field of cotton textile machinery technology, specifically to a circuit board fuse device for a roll inspection machine. Background Technology

[0002] Fabric inspection machines are used to detect the warp and weft density and defects (such as broken yarns, skipped yarns, and color variations) of fabrics. In the production of high-end garment fabrics, inspection machines can strictly screen out qualified fabrics to ensure garment quality. However, when the solenoid valve coil inside the inspection machine overheats, bulges, or burns out, the lack of a safety device between the coil and the control circuit board means that a short circuit will cause the control circuit board to burn out. Furthermore, the high cost and long repair time of replacing the control circuit board disrupt normal production. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention aims to provide a circuit board fuse device for a test paper inspection machine, which solves the problem that when the solenoid valve coil in the test paper inspection machine overheats and bulges or burns out, the control circuit board is prone to short circuit and burnout due to the direct connection between the solenoid valve coil and the control circuit board.

[0004] To achieve the above-mentioned objectives, the circuit board fuse device for the paper inspection machine of the present invention mainly includes a circuit board body. A lower horizontal plate is fixedly connected to the upper surface of the circuit board body, and a U-shaped plate is fixedly connected to the upper surface of the lower horizontal plate. A first circular hole is provided on both the left and right sides of the U-shaped plate. An arc-shaped conductive plate is fixedly connected to the inner wall of the first circular hole. A fuse body is attached to the upper surface of the arc-shaped conductive plate and the inner wall of the first circular hole. Limiting rings are attached to the left and right sides of the fuse body and the surface of the U-shaped plate. An upper horizontal plate is fixedly connected to the left and right sides of the inner wall of the limiting ring. A spring is fixedly connected to the bottom of the upper horizontal plate and the upper surface of the lower horizontal plate. A first terminal is fixedly connected to the upper surface of the circuit board body. A second terminal is fixedly connected to the upper surface of the circuit board body. A second circular hole is provided on both the left and right sides of the U-shaped plate. Conductive posts are fixedly connected to the inner walls of the first terminal, the second terminal, the second circular hole, and the bottom of the arc-shaped conductive plate.

[0005] Furthermore, a support plate is fixedly connected to the right side of the limiting ring, and a rubber sleeve is fitted to the surface of the support plate. Positioning plates are glued to both the upper and lower sides of the rubber sleeve. A groove is opened on the side of the U-shaped plate near the upper horizontal plate, and the inner wall of the groove is fitted to the surface of the positioning plate.

[0006] Furthermore, the frictional force between the rubber sleeve and the support plate is greater than the sum of the weights of the positioning plate and the rubber sleeve.

[0007] Furthermore, an observation hole is provided on the upper surface of the U-shaped plate, and the observation hole is located directly above the fuse body.

[0008] Furthermore, the upper surface of the limiting ring is provided with an arc-shaped groove, which is located on the right side of the fuse body, and the diameter of the arc-shaped groove is equal to the diameter of the fuse body.

[0009] Furthermore, a pressing spring is fixedly connected to the top of the inner wall of the U-shaped plate, and the bottom of the pressing spring is attached to the upper surface of the fuse body.

[0010] Compared with the prior art, the technical effects achieved by this invention are as follows: 1. By using the lower horizontal plate, U-shaped plate, first circular hole, arc-shaped conductive plate, limiting ring, upper horizontal plate and spring, the fuse body can be fixed on the circuit board body. By using the arc-shaped conductive plate, first terminal, second terminal and conductive post, the solenoid valve coil in the test paper inspection machine is connected to the circuit board body through the fuse body. The fuse body prevents the circuit board body from burning out when the solenoid valve coil fails. Thus, by replacing the solenoid valve coil and the fuse body, the test paper inspection machine can be restored to normal operation, and maintenance costs can be reduced.

[0011] 2. Through the friction between the rubber sleeve and the support plate, the rubber sleeve can be fixed in the groove after it is put on the support plate. The positioning plate and the groove can lock the limiting ring, so that when the maintenance personnel are repairing the circuit board body, they will not accidentally touch the support plate, which would cause the limiting ring to separate from the fuse body and cause the fuse body to detach from the U-shaped plate.

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the circuit board fuse device of the paper inspection machine of the present invention mainly includes a circuit board body 1. A lower horizontal plate 2 is fixedly connected to the upper surface of the circuit board body 1. A U-shaped plate 3 is fixedly connected to the upper surface of the lower horizontal plate 2. A first circular hole 4 is provided on both the left and right sides of the U-shaped plate 3. An arc-shaped conductive plate 5 is fixedly connected to the inner wall of the first circular hole 4. A fuse body 6 is attached to the upper surface of the arc-shaped conductive plate 5 and the inner wall of the first circular hole 4. Limiting rings 7 are attached to the left and right sides of the fuse body 6 and the surface of the U-shaped plate 3. An upper horizontal plate 8 is fixedly connected to the left and right sides of the inner wall of the limiting ring 7. A spring 9 is fixedly connected to the bottom of the upper horizontal plate 8 and the upper surface of the lower horizontal plate 2. A first terminal is fixedly connected to the upper surface of the circuit board body 1. 10. A second terminal block 11 is fixedly connected to the upper surface of the circuit board body 1. A second round hole 12 is opened on both the left and right sides of the U-shaped plate 3. Conductive posts 13 are fixedly connected to the inner wall of the first terminal block 10, the inner wall of the second terminal block 11, the inner wall of the second round hole 12, and the bottom of the arc-shaped conductive plate 5. An observation hole 18 is opened on the upper surface of the U-shaped plate 3. The observation hole 18 is located directly above the fuse body 6. An arc-shaped groove 19 is opened on the upper surface of the limiting ring 7. The arc-shaped groove 19 is located on the right side of the fuse body 6. The diameter of the arc-shaped groove 19 is equal to the diameter of the fuse body 6. A pressing spring 20 is fixedly connected to the top of the inner wall of the U-shaped plate 3. The bottom of the pressing spring 20 is attached to the upper surface of the fuse body 6.

[0022] After the fuse body 6 is inserted into the first circular hole 4, the spring force of the spring 9 causes both ends of the fuse body 6 to fit against the inner wall of the limiting ring 7, and the limiting ring 7 fixes the fuse body 6 to the arc-shaped conductive plate 5. At this time, through the cooperation of the arc-shaped conductive plate 5 and the conductive post 13, the first terminal 10 and the second terminal 11 are electrically connected to the fuse body 6. Then, the first terminal 10 is connected to the terminal on the circuit board body 1, and the second terminal 11 is connected to the terminal on the solenoid valve coil. At this time, the solenoid valve coil is connected to the circuit board body 1 through the fuse body 6, and... The fuse body 6 prevents the circuit board body 1 from burning out when the solenoid valve coil fails. When the limiting ring 7 is misaligned with the fuse body 6, the fuse body 6 can be directly removed from the first circular hole 4. When the fuse body 6 is in contact with the arc groove 19, the arc groove 19 can be used to position the fuse body 6 and make the axis of the fuse body 6 directly above the center of the first circular hole 4. When the fuse body 6 is inserted into the first circular hole 4, the spring force of the pressing spring piece 20 makes the fuse body 6 and the arc conductive plate 5 make tight contact. At the same time, the user can observe whether the fuse body 6 is damaged through the observation hole 18.

[0023] A support plate 14 is fixedly connected to the right side of the limiting ring 7. A rubber sleeve 15 is fitted onto the surface of the support plate 14. Positioning plates 16 are bonded to both the upper and lower sides of the rubber sleeve 15. A groove 17 is formed on the side of the U-shaped plate 3 near the upper horizontal plate 8. The inner wall of the groove 17 is fitted to the surface of the positioning plate 16. The friction between the rubber sleeve 15 and the support plate 14 is greater than the sum of the weights of the positioning plate 16 and the rubber sleeve 15. Through the friction between the rubber sleeve 15 and the support plate 14, the positioning plate 16 can be fixed in the groove 17 after the rubber sleeve 15 is fitted onto the support plate 14. The cooperation between the positioning plate 16 and the groove 17 locks the limiting ring 7, thus preventing the maintenance personnel from accidentally touching the support plate 14 when repairing the circuit board body 1, which would cause the limiting ring 7 to separate from the fuse body 6 and cause the fuse body 6 to detach from the U-shaped plate 3.

[0024] The working principle of this invention is as follows: First, the fuse body 6 is attached to the arc groove 19. Then, the limiting ring 7 is moved downward by pressing the fuse body 6. When the fuse body 6 is aligned with the first circular hole 4, the fuse body 6 is inserted into the first circular hole 4 by moving the fuse body 6 horizontally. The fuse body 6 is then brought into close contact with the arc conductive plate 5 by pressing the elastic force of the spring piece 20.

[0025] When the left and right ends of the fuse body 6 are aligned with the left and right sides of the U-shaped plate 3, the spring force of the spring 9 causes the limiting ring 7 to move upward, and the limiting ring 7 fixes the fuse body 6 on the arc-shaped conductive plate 5. At this time, through the cooperation of the arc-shaped conductive plate 5 and the conductive post 13, the first terminal 10 and the second terminal 11 are electrically connected to the fuse body 6. Then, the first terminal 10 is connected to the terminal on the circuit board body 1, and the second terminal 11 is connected to the terminal on the solenoid valve coil. At this time, the solenoid valve coil is connected to the circuit board body 1 through the fuse body 6, and through the fuse body 6, the circuit board body 1 will not burn out when the solenoid valve coil fails.

[0026] When the fuse body 6 is damaged, first attach the new fuse body 6 to the arc groove 19. Then, press the fuse body 6 to move the limiting ring 7 downward. When the new fuse body 6 is aligned with the old fuse body 6, push the new fuse body 6 to the left to move the old fuse body 6 out of the U-shaped plate 3 and push the new fuse body 6 into the first round hole 4.

[0027] When the left and right ends of the new fuse body 6 are aligned with the left and right sides of the U-shaped plate 3, the spring force of the spring 9 causes the limiting ring 7 to move upward, and the limiting ring 7 fixes the new fuse body 6 on the arc-shaped conductive plate 5.

[0028] After the fuse body 6 is fixed on the arc-shaped conductive plate 5, the rubber sleeve 15 is put on the support plate 14, so that the positioning plate 16 is fixed in the groove 17 under the action of friction between the rubber sleeve 15 and the support plate 14. The limiting ring 7 can be locked by the cooperation of the positioning plate 16 and the groove 17. When the fuse body 6 needs to be replaced, the positioning plate 16 is moved out of the groove 17 to release the locking of the limiting ring 7.

[0029] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention are implemented according to conventional methods in the art unless otherwise specified or limited.
