[0002] Corrugated cardboard is also called corrugated cardboard. It is made of at least one layer of corrugated paper and one layer of boxboard, and has good elasticity and extensibility. It is mainly used to make cartons, the sandwich of cartons, and other packaging materials for fragile goods. It is mainly made of traditional straw pulp and waste paper through pulping to make a raw cardboard similar to yellow cardboard, which is then machined and rolled into a corrugated shape, and then the surface is bonded with the boxboard with adhesives such as sodium silicate.

[0003] The utility model with existing announcement number: CN 220398485 U discloses a corrugated cardboard warping detection device, including a bracket and a controller, a conveying device is installed on the bracket, and a top plate is installed on the bracket; a plurality of rollers are arranged on the upper side of the conveying device, and friction pads are wrapped on the outer sides of the rollers. Two groups of rollers are arranged, and the rollers in each group are distributed in a linear array along the conveying device, and the two rollers are respectively located at the left and right ends of the upper side of the conveying device.

[0004] During the use of the above device, the laser emitting device and the receiving device are in a fixed state. When the two sides of the corrugated cardboard are flat but the middle is bent, it cannot be accurately detected, which may lead to an increase in the defective rate and increase the production cost of the enterprise. For this reason, we propose a corrugated cardboard warping detection device. Utility Model Content

[0007] The bracket is the main body of the device. The corrugated cardboard is placed on the conveyor belt, and the conveyor belt drives the corrugated cardboard to move. At this time, the laser transmitter in the laser instrument sleeve works, and the servo motor is started. The servo motor drives the threaded rod to rotate, and the rotation of the threaded rod drives the slider to move. The movement of the slider drives the laser receiver and transmitter in the laser instrument sleeve to slide. By driving the laser equipment to move, it can effectively avoid the situation that when the corrugated cardboard is bent in the middle and the two sides are flat during detection by the laser detector, the instrument may not detect accurately, thereby resulting in an increase in the defective rate and an increase in the company's production costs.

[0008] As a preferred technical solution of the utility model, the cleaning assembly includes a bevel gear 1, the outer wall of the threaded rod is provided with a sliding groove that cooperates with the bevel gear 1 to slide, a bevel gear 2 is installed on one side of the inner wall of the elongated plate, the bevel gear 2 is meshed and connected with the bevel gear 1, the outer wall of the bevel gear 1 is rotatably connected with a rotating shaft, the inner ring of the rotating shaft is fixedly connected with the bevel gear 1, the outer ring of the rotating shaft is fixedly connected with a spring, the other end of the spring is fixedly connected with the slider, and a brush is installed in the middle of the bevel gear 2:

[0009] A bevel gear 1 is installed on the outer wall of the threaded rod, and a slide groove is provided to cooperate with the movement of the bevel gear 1. When the threaded rod rotates, the bevel gear 1 is driven to rotate and move along the slide groove. When the bevel gear 1 moves to the appropriate position, it meshes with the bevel gear 2. The elasticity of the spring squeezes the bevel gear 1 so that the bevel gear 1 can accurately mesh with the bevel gear, thereby driving the bevel gear 2 and the brush to rotate. At this time, the equipment in the laser instrument sleeve is close to the brush, and the dust on the surface of the laser instrument is cleaned by the rotation of the brush to prevent the dust from scattering and blocking the laser, resulting in deviations in the measurement data.

[0010] The beneficial effects of the utility model are as follows: by driving the laser device to move, it can effectively avoid that when the laser detector detects, the corrugated cardboard is bent in the middle and flat on both sides, and the instrument may not be able to accurately identify it, resulting in inaccurate detection, thereby leading to an increase in the defective rate and increasing the production cost of the enterprise.

[0011] The utility model cleans the dust on the surface of the laser instrument by rotating the brush, so as to prevent the dust from scattering and blocking the laser and causing deviation in the measurement data. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The bracket 1 is the bearing body of the device. The corrugated cardboard is placed on the conveyor belt 5, and the conveyor belt 5 drives the corrugated cardboard to move. At this time, the laser transmitter in the laser instrument sleeve 305 works, and the servo motor 302 is started. The servo motor 302 drives the threaded rod 303 to rotate, and the rotation of the threaded rod 303 drives the slider 304 to move. The movement of the slider 304 drives the laser receiver and transmitter in the laser instrument sleeve 305 to slide. By driving the laser equipment to move, it can effectively avoid that when the laser detector detects, the corrugated cardboard is bent in the middle and flat on both sides, which may cause the instrument data detection to be inaccurate, thereby resulting in an increase in the defective rate and an increase in the company's production costs.

[0023] See also Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, the cleaning assembly 4 includes a bevel gear 401, and the outer wall of the threaded rod 303 is provided with a sliding groove 402 for cooperating with the sliding of the bevel gear 401, and a bevel gear 2 403 is installed on one side of the inner wall of the elongated plate 301, and the bevel gear 2 403 is meshed and connected with the bevel gear 401, and the outer wall of the bevel gear 401 is rotatably connected with a rotating shaft 405, and the inner ring of the rotating shaft 405 is fixedly connected to the bevel gear 401, and the outer ring of the rotating shaft 405 is fixedly connected to a spring 406, and the other end of the spring 406 is fixedly connected to the slider 304, and a brush 404 is installed in the middle of the bevel gear 2 403.

[0024] A bevel gear 401 is installed on the outer wall of the threaded rod 303, and a slide groove 402 is also provided to cooperate with the movement of the bevel gear 401. When the threaded rod 303 rotates, the bevel gear 401 is driven to rotate and move along the slide groove 402. When the bevel gear 401 moves to a suitable position, it meshes with the bevel gear 2 403. The bevel gear 401 is elastically squeezed by the spring 406, so that the bevel gear 401 can accurately mesh with the bevel gear 2 403, thereby driving the bevel gear 2 403 and the brush 404 to rotate. At this time, the equipment in the laser instrument sleeve 305 is close to the brush 404. The dust on the surface of the laser instrument is cleaned by the rotation of the brush 404 to prevent the dust from scattering and blocking the laser, resulting in deviations in the measurement data.

[0025] Working principle: Place the corrugated cardboard on the conveyor belt 5, and the conveyor belt 5 drives the corrugated cardboard to move. At this time, the laser transmitter in the laser instrument sleeve 305 works, and the servo motor 302 is started. The servo motor 302 drives the threaded rod 303 to rotate. The rotation of the threaded rod 303 drives the slider 304 to move. The movement of the slider 304 drives the laser receiver and transmitter in the laser instrument sleeve 305 to slide. By driving the laser device to move, it can effectively avoid the corrugated cardboard bending in the middle and flat on both sides during the laser detector detection, which causes inaccurate detection. The threaded rod 303 rotates. When rotating, it drives bevel gear 1 401 to rotate and move along slide groove 402. When bevel gear 1 401 moves to a suitable position, it meshes with bevel gear 2 403. The elasticity of spring 406 squeezes bevel gear 1 401, so that bevel gear 1 401 can accurately mesh with bevel gear 2 403, thereby driving bevel gear 2 403 and brush 404 to rotate. At this time, the equipment in the laser instrument sleeve 305 is close to brush 404. The dust on the surface of the laser instrument is cleaned by the rotation of brush 404 to prevent dust from scattering and blocking the laser, resulting in deviations in the measurement data.
