Description

Technical Field

[0002] Hollow board is a new type of material made of environmentally friendly thermoplastic materials (such as PP, HDPE, PC). It is light, non-toxic, environmentally friendly, waterproof, moisture-proof, shock-proof, anti-aging, corrosion-resistant and colorful. It is widely used in electronics, packaging, advertising, construction, home and many industrial fields. Its market demand is growing; However, in the traditional production process of hollow boards, cutting is an indispensable step but is prone to problems. In order to obtain the size that meets the requirements of specific applications, the hollow boards need to be processed by precision cutting equipment. However, in this process, due to the physical properties of the material itself, the wear of the cutting tool, improper setting of cutting parameters and other factors, the cut surface of the hollow board is often prone to burrs. These burrs not only affect the appearance quality of the product, but may also scratch adjacent components during use, reduce the stability and service life of the overall structure, and even cause safety hazards in some sensitive application areas. Traditional practices usually require manual or simple mechanical devices to perform secondary processing on the cut surface to remove burrs, but this method is not only inefficient and increases production costs, but also difficult to ensure the consistency and thoroughness of the processing.

[0003] In view of the above problems, the inventors propose a production method and equipment for enhancing the surface hardness of hollow plates to solve the above problems. Summary of the invention

[0040] By adopting the above technical solution, under the limitation of the second limiting rod 404 , the two limiting plates 405 can be driven to move stably relative to or away from each other by the rotation of the second double-headed screw 403 .

[0041] Working principle: After the hollow board is cut by the cutting device, the board falls to the top of the second conveyor belt 402, and the second conveyor belt 402 is driven by the servo motor to rotate, and the hollow board is transported to the top of the placement plate 301. The second double-headed screw 403 is rotated to drive the limiting plate 405 to move relative or opposite to each other to adjust the distance between the two, so as to position the hollow board to the middle of the top of the placement plate 301, and the hollow board is adsorbed by the suction cup 116; The first motor 102 drives the synchronous wheel 103 to rotate, thereby driving the cam 107 and the rotating shaft 104 to rotate. First, one end of the cam 107 slides in the middle of the moving block 108, and at this time, the driving rod 105 is driven to rotate by the rotation of the rotating shaft 104, so that one end of the driving rod 105 is slidably clamped in the second groove 114. Since the second groove 114 is spirally arranged, the rotation of the driving rod 105 drives the rotating shaft 112 to rotate 180°. Under the limit of the limit block 111, the sliding rod 110 is driven to rotate, that is, the suction cup 116 is driven to rotate, so that the upper hollow plate is driven to rotate 180° so that its cutting surface is located on one side of the soft brush 320. At this time, the end of the driving rod 105 is away from the middle of the second groove body 114, and at the same time, one side of the arc plate 106 is slidably clamped in the middle of the second groove body 114. At this time, under the rotation of the cam 107, the moving block 108 is moved downward in cooperation with the moving block 108, thereby driving the support rod 109 to move downward, that is, the sliding rod 110 is moved downward, thereby driving the suction cup 116 to move downward, and through the downward movement of the suction cup 116, the placement plate 301 is driven to move downward, that is, the tooth plate 303 moves downward, so that the meshing gear 306 rotates, that is, drives the first double-headed screw 305 to rotate, so that the two moving plates 307 move relative to each other, that is, drives the two fixed blocks 311 to move relative to each other, so that the soft brush 320 and the two sides of the hollow plate contact each other. At this time, the first motor 102 stops driving; The second motor 314 is started, driving the rotating disk 315 to rotate, thereby rotating the eccentric block 317, that is, driving the limit shell 316 to move. Since the moving rod 318 is slidably clamped in the middle of the cavity 319, the rotation of the eccentric block 317 drives the moving rod 318 to move back and forth, that is, drives the soft brush 320 to move back and forth, and removes the burrs on the cutting surfaces of both sides of the hollow plate. At the same time, the vacuum cleaner 201 is started, and the burrs removed by the reciprocating movement of the soft brush 320 are sucked away by the cooperation of the suction nozzle 203 and the guide tube 202; When the burr cleaning is completed, the second motor 314 stops working and the first motor 102 is started, so that the synchronous wheel 103 continues to rotate, and then the sliding rod 110 moves upward through the rotation of the arc plate 106 and the cam 107, that is, the suction cup 116 moves upward, thereby driving the placement plate 301 to move upward to reset it. After resetting, the driving rod 105 and the second slot body 114 cooperate with each other to make the rotating shaft 112 rotate, so that the suction cup 116 rotates, and then drives the upper adsorbed hollow plate to rotate to reset it, and stops the drive of the first motor 102. At the same time, the suction cup 116 releases the adsorption of the hollow plate, and the first conveyor belt 302 is driven by the servo motor to rotate, so as to transport the hollow plate at the top of the placement plate 301 to the other side for centralized collection, that is, completing a hollow plate burr removal work.
