Description

Technical Field

[0001] This utility model relates to the technical field of paper-insulated wire quality testing, and in particular to a paper-insulated wire diameter testing device. Background Technology

[0002] Paper-insulated wires are a type of electrical wire with a specific insulation layer, where the conductor is wrapped in a layer of paper as insulation material. During the production process, the outer diameter of paper-insulated wires may become unstable, or bulging may occur in the outer sheath during processing. To improve wire quality, substandard wires are usually screened out before packaging.

[0003] Currently, screening and testing are usually carried out manually. When the number of abnormal wires is large, a large number of workers are required, which increases labor costs. In addition, the labor intensity of workers is also high, and the testing efficiency is low. Therefore, this utility model proposes a paper-insulated wire diameter testing device that is different from the existing technology to solve the above-mentioned technical problems. Utility Model Content

[0004] To address the aforementioned issues of high labor costs, high worker workload, and low detection efficiency when dealing with a large number of abnormal wires, this invention provides a paper-insulated wire diameter detection device.

[0005] This utility model provides a device for detecting the diameter of paper-insulated wires, which adopts the following technical solution:

[0006] A paper-wrapped wire diameter detection device includes a detection platform. A mounting platform is fixed to the rear side of the top wall of the detection platform. Multiple sets of lifting assemblies are uniformly fixed to the top wall of the inner cavity of the mounting platform. Multiple sets of detection rollers are rotatably connected to the bottom ends of the multiple sets of lifting assemblies. Infrared ranging sensors are installed on each of the multiple sets of lifting assemblies. A PLC controller and a buzzer alarm are respectively installed on both sides of the top wall of the mounting platform. The PLC controller is electrically connected to the buzzer alarm and the infrared ranging sensors.

[0007] By adopting the above technical solution, the detection roller is pressed onto the upper surface of the paper-wrapped wire. When the wire diameter is too large or too small, the detection roller can move up and down, thereby driving the hoisting assembly to retract. Under the action of the infrared distance sensor, the hoisting frame can be detected to move a certain distance and automatically transmit the signal to the PLC controller. The PLC controller controls the buzzer alarm to start and generate an alarm to remind the staff, thereby improving the efficiency of detection.

[0008] Optionally, the hoisting assembly includes a hoisting vertical pipe, which is fixed to the top wall of the inner cavity of the mounting platform. The infrared ranging sensor is fixed to the top wall of the inner cavity of the hoisting vertical pipe. A hoisting frame penetrating the bottom wall of the hoisting vertical pipe is provided at the bottom end of the inner cavity of the hoisting vertical pipe. The detection roller is rotatably sleeved on the bottom end of the outer wall of the hoisting frame.

[0009] By adopting the above technical solution, the up-and-down movement of the detection roller can drive the hoisting frame to move vertically synchronously within the inner cavity of the hoisting vertical pipe. Under the action of the infrared distance sensor, the movement distance of the hoisting frame can be detected.

[0010] Optionally, multiple sets of dividing vertical plates are evenly fixed to the top wall of the testing platform, and wire guide plates are installed at both ends of the top wall of the testing platform. Multiple sets of wire guide holes are opened in the inner cavity of the wire guide plates.

[0011] By adopting the above technical solution, multiple sets of paper-wrapped wires can be detected simultaneously under the action of multiple sets of wire holes and dividing vertical plates, thereby improving detection efficiency.

[0012] Optionally, multiple sets of vertical support plates are fixed to the bottom wall of the testing platform, and vertical support frames are movably fitted onto the bottom ends of the outer walls of the multiple sets of vertical support plates. The vertical support plates and vertical support frames are connected to each other by threaded assemblies.

[0013] Optionally, the threaded assembly includes a positioning bolt, which is inserted at the upper end of the outer wall of the vertical support frame, and the outer wall of the vertical support plate has a plurality of positioning screw holes that are evenly provided to match the threads of the positioning bolt.

[0014] By adopting the above technical solution, the vertically moving testing platform drives the vertical support plate to move synchronously to an appropriate height in the inner cavity of the vertical support frame. By screwing the positioning bolts to make them threadedly connected with the positioning screw holes at the corresponding height, the height of the testing platform above the ground can be adjusted.

[0015] Optionally, the bottom wall of the vertical support frame is fixed with casters.

[0016] By adopting the above technical solution, the position of the paper-wrapped wire diameter detection device can be easily moved using multiple sets of movable wheels.

[0017] In summary, this utility model has at least one of the following beneficial effects: the detection roller is pressed onto the upper surface of the paper-wrapped wire. When the wire diameter is too large or too small, the detection roller can move up and down, thereby driving the hoisting frame to move vertically synchronously within the hoisting vertical pipe. Under the action of the infrared ranging sensor, the signal is automatically transmitted to the PLC controller after the hoisting frame moves a certain distance. The PLC controller controls the buzzer alarm to start, thereby reminding the staff to perform manual or mechanical retesting, improving the efficiency of detection. At the same time, the design of multiple detection rollers can automatically repeat the detection multiple times, which can effectively reduce the possibility of missed detection.

Detailed Implementation

[0021] The following is in conjunction with the appendix Figure 1-2 The present invention will be described in further detail below.

[0022] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 This utility model provides an embodiment of a paper-wrapped wire diameter detection device, including a detection platform 8, both ends of which are semi-circular. A mounting platform 14 is fixed to the rear side of the top wall of the detection platform 8. The lateral longitudinal section of the mounting platform 14 is L-shaped. Multiple sets of hoisting components are uniformly fixed to the top wall of the inner cavity of the mounting platform 14. The hoisting components include a hoisting vertical pipe 1, which is fixed to the top wall of the inner cavity of the mounting platform 14. An infrared ranging sensor 12 is installed on the top wall of the inner cavity of the hoisting vertical pipe 1. A hoisting frame 2 is provided at the bottom end of the inner cavity of the hoisting vertical pipe 1, penetrating the bottom wall of the hoisting vertical pipe 1. A detection roller 7 is rotatably sleeved at the bottom end of the outer wall of the hoisting frame 2. A PLC controller 15 and a buzzer alarm 13 are respectively installed on both sides of the top wall of the mounting platform 14. The PLC controller 15 is electrically connected to the buzzer alarm 13 and the infrared ranging sensor 12.

[0023] The detection roller 7 presses against the upper surface of the paper-wrapped wire. When the wire diameter is too large or too small, the detection roller 7 can move up and down, thereby driving the hoisting frame 2 to move vertically synchronously within the hoisting vertical pipe 1. Under the action of the infrared distance sensor 12, the hoisting frame 2 can be detected to have moved a certain distance. Once this distance reaches a certain limit, the sensor automatically transmits the signal to the PLC controller 15. The PLC controller 15 then controls the buzzer alarm 13 to activate and generate an alarm to alert the staff.

[0024] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 Multiple sets of dividing vertical plates 6 are evenly fixed to the top wall of the testing table 8. These dividing vertical plates 6 and multiple sets of testing rollers 7 are staggered. Guide plates 11 are installed at both ends of the top wall of the testing table 8, and the inner cavity of the guide plates 11 has multiple sets of guide holes 3. The paper-packaged wire to be tested is passed through the corresponding guide holes 3 and positioned between the dividing vertical plates 6. Under the action of the multiple guide holes 3 and the dividing vertical plates 6, multiple sets of paper-packaged wires can be tested simultaneously, improving testing efficiency.

[0025] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 The bottom wall of the testing platform 8 is fixed with multiple sets of vertical support plates 5. A vertical support frame 4 is movably fitted onto the bottom end of the outer wall of each set of vertical support plates 5. The top end of the vertical support frame 4 is open. The vertical support plates 5 and the vertical support frame 4 are connected to each other via a threaded assembly. The threaded assembly includes a positioning bolt 10, which passes through the upper end of the outer wall of the vertical support frame 4. Multiple sets of positioning screw holes 9, matching the threads of the positioning bolts 10, are evenly distributed on the outer wall of the vertical support plates 5.

[0026] The vertically moving test platform 8 drives the vertical support plate 5 to move synchronously to an appropriate height within the inner cavity of the vertical support frame 4. Tightening the positioning bolt 10 makes it threadedly connected to the positioning screw hole 9 at the corresponding height, thereby adjusting the height of the test platform 8 from the ground.

[0027] Please refer to the attached diagram in the instruction manual. Figure 1 and 2 The bottom wall of the vertical support frame 4 is fixed with casters 16, which are self-locking casters. Multiple sets of casters 16 facilitate the movement of the paper-packaged wire diameter detection device.

[0028] Working principle: When using this paper-wrapped wire diameter detection device, the paper-wrapped wire to be tested is passed through the wire hole 3 at the corresponding position and placed at the interval of multiple sets of vertical partition plates 6. At the same time, the end of the paper-wrapped wire to be tested is fixed to the existing transmission device. The transmission device drives the paper-wrapped wire to move. When the paper-wrapped wire is on the top wall of the detection table 8, the detection roller 7 can be pressed against the upper surface of the paper-wrapped wire under the action of gravity. During the movement of the paper-wrapped wire, the detection roller 7 can be driven to rotate synchronously.

[0029] When the wire diameter of the paper-wrapped conductor is too large or too small, the detection roller 7 can move up and down, thereby driving the hoisting frame 2 to move vertically synchronously within the inner cavity of the hoisting vertical pipe 1. Under the action of the infrared distance sensor 12, the hoisting frame 2 can be detected to have moved a certain distance and then automatically transmit the signal to the PLC controller 15. The PLC controller 15 controls the buzzer alarm 13 to start and generate an alarm to remind the staff, so that the staff can perform manual or mechanical retesting, thereby improving the efficiency of the detection.

[0030] With the help of multiple sets of wire holes 3 and the dividing vertical plate 6, multiple sets of paper-wrapped wires can be tested at the same time, improving the testing efficiency. Multiple sets of moving wheels 16 facilitate the movement of the paper-wrapped wire diameter testing device. The up-and-down moving testing platform 8 drives the vertical support plate 5 to move synchronously to an appropriate height in the inner cavity of the vertical support frame 4. Tightening the positioning bolt 10 makes it threadedly connected with the positioning screw hole 9 at the corresponding height, thereby adjusting the height of the testing platform 8 from the ground.
