Abstract
Description
Technical Field
[0001] This utility model relates to the field of white pad polishing technology, and in particular to a polishing device for white pad production. Background Technology
[0002] White pad board, also known as medium-density fiberboard, is an ideal engineered wood product for furniture making. During production, the surface of white pad board needs polishing. Existing white pad board polishing equipment often uses a fixed upper pressure plate structure, which can only polish one side of the board, resulting in low processing efficiency. Furthermore, this type of fixing method often uses a rigid pressure plate structure, requiring manual adjustment of the gap when dealing with boards with significant thickness differences, leading to long changeover times and reduced production efficiency. In addition, the direct connection between the conveyor belt and the polishing surface means the lower surface can only rely on static friction, resulting in insufficient polishing removal. Therefore, a polishing device for white pad board production is urgently needed. Utility Model Content
[0003] The purpose of this invention is to address the deficiencies in the existing technology by proposing a polishing device for the production of white pads.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A polishing device for producing white pad boards includes a base, a conveyor belt at the top of the base, a polishing layer on the surface of the conveyor belt, a ball bearing slide rail between the polishing layer and the conveyor belt, and the polishing layer achieving a composite motion of lateral vibration and longitudinal conveying through the ball bearing slide rail. A vibration motor is provided on one side of the polishing layer to cooperate with it.
[0006] The base has an elastic pressure mechanism at its top, which is connected to the base via several guide posts. The guide posts are located at the four corners of the base. The bottom of the elastic pressure mechanism has a pressure block that cooperates with the conveyor belt, and the bottom of the pressure block has a polishing plate.
[0007] Furthermore, the elastic pressure mechanism includes a fixed top plate and a cross slide, the end of which is connected to the guide post via a sliding sleeve.
[0008] Several pressure springs are provided between the fixed top plate and the cross slide.
[0009] Furthermore, the guide post has a cylindrical structure and is provided with several annular grooves, and the annular grooves are provided with limiting sleeves.
[0010] Furthermore, one side of the sliding sleeve is provided with a spring telescopic rod that passes through the cross slide. The spring telescopic rod is provided with several limiting grooves that cooperate with the cross slide. The limiting grooves are provided with limiting pins, and the limiting pins pass through the cross slide.
[0011] Furthermore, the pressure block is a hollow wedge-shaped structure, and the thick end of the pressure block is hinged to the cross slide by several hinges. Several functional springs are provided between the pressure block and the cross slide.
[0012] Furthermore, one side of the polishing plate is hinged to the pressure block, and a plurality of ejector springs are provided between the polishing plate and the pressure block, the ejector springs extending through the bottom surface of the pressure block into the interior of the pressure block.
[0013] Furthermore, the pressure block has a moving groove on its side, and a rotating buckle is provided on the moving groove. One end of the rotating buckle is provided with a locking pin that cooperates with the moving groove, and the other end is connected to the polishing plate through the rotating pin.
[0014] Furthermore, a guide lip plate is provided on the side of the pressure block near the feed inlet. The guide lip plate is inclined upward along the horizontal line, and the inclination angle of the guide lip plate forms a continuous transition with the slope angle of the pressure block.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: by the synergistic effect of the upper and lower double polishing surfaces of the conveyor belt and the pressure block, double-sided polishing can be achieved in a single processing, thereby improving processing efficiency. The use of an elastic pressure mechanism, through the cooperation of the pressure spring and the limiting groove, enables automatic thickness adjustment and automatic compensation for pressure deviation when the thickness changes abruptly, avoiding crushing of the board or insufficient polishing. In particular, the guide lip plate ensures smooth board feeding, reduces the jamming rate, and is compatible with various board materials such as cork, hard plastic, and composite boards.

[0025] Reference Figure 1-5 A polishing device for white pad production includes a base 1, a conveyor belt 2 at the top of the base 1, a polishing layer 3 on the surface of the conveyor belt 2, a ball slide rail 4 between the polishing layer 3 and the conveyor belt 2, the polishing layer 3 achieving a composite motion of transverse vibration and longitudinal conveying through the ball slide rail 4, and a vibration motor cooperating with the polishing layer 3 on one side.
[0026] The base 1 is provided with an elastic pressure mechanism 6 at its top. The elastic pressure mechanism 6 is connected to the base 1 through several guide posts 7. The guide posts 7 are located at the four corners of the base 1. The bottom end of the elastic pressure mechanism 6 is provided with a pressure block 8 that cooperates with the conveyor belt 2. The bottom end of the pressure block 8 is provided with a polishing plate 9. In a specific embodiment, the surface of the conveyor belt 2 is bonded with a diamond polishing layer 3, and the bottom is laterally slidable through a ball bearing slide rail 4. The X-axis direction of the ball bearing slide rail 4 is perpendicular to the forward direction of the conveyor belt 2. The vibration motor 5 is installed on the side of the conveyor belt 2 to drive the polishing layer 3 to generate lateral vibration. The four guide posts 7 are vertically welded to the four corners of the base 1 and connected to the elastic pressure mechanism 6 at the top. The bottom surface of the pressure block 8 is detachably equipped with an alumina polishing plate 9. When the conveyor belt 2 drives the white pad to move longitudinally, the vibration motor 5 causes the polishing layer 3 to vibrate laterally, generating a planar composite motion. The pressure block 8 is pressed down under the action of the elastic pressure mechanism 6, forming a double-sided polishing structure with the conveyor belt 2. The ball bearing slide rail 4 reduces the sliding friction of the polishing layer 3 and ensures smooth high-frequency vibration.
[0027] The elastic pressure mechanism 6 includes a fixed top plate 10 and a cross slide 11, the end of which is connected to the guide post 7 via a sliding sleeve 12.
[0028] Several pressure springs 13 are provided between the fixed top plate 10 and the cross slide 11.
[0029] The guide post 7 is a cylindrical structure with several annular grooves 14. Each annular groove 14 is equipped with a limiting sleeve 15. In one specific embodiment, the elastic pressure mechanism 6 consists of a fixed top plate 10 and a cross slide 11. The four ends of the cross slide 11 are connected to the guide post 7 through sliding sleeves 12 with ball bearings. Several sets of pressure springs 13 are evenly arranged between the fixed top plate 10 and the cross slide 11. The limiting sleeve 15 adopts a split clamp structure to cooperate with the annular grooves 14 machined on the surface of the guide post 7 and can be quickly locked in any annular groove 14. When the thickness of the plate changes, the cross slide 11 rises and falls along the guide post 7, the pressure springs 13 adjust the compression amount, and the limiting sleeve 15 forms a mechanical hard limit after being inserted into the annular groove 14 to prevent the spring from overloaded.
[0030] One side of the sliding sleeve 12 is provided with a spring telescopic rod 16 that passes through the cross slide 11. The spring telescopic rod 16 is provided with several limiting grooves 17 that cooperate with the cross slide 11. The limiting grooves 17 are provided with limiting pins 18, which pass through the cross slide 11. In one specific embodiment, the spring telescopic rod 16 is welded to the inner side of the sliding sleeve 12, and the surface of the telescopic rod 16 is provided with the limiting grooves 17 at intervals. The limiting pins 18 pass through the cross slide 11 and are inserted into the limiting grooves 17, and are provided with anti-disengagement springs at their ends. During use, the cross slide 11 can be finely adjusted in position by adjusting the length of its cooperation with the spring telescopic rod 16, and it is convenient for overall installation and disassembly. When the movement of the plate is obstructed, the adjustable elastic space allows the cross slide 11 to provide a certain amount of clearance.
[0031] The pressure block 8 is a hollow wedge-shaped structure. The thick end of the pressure block 8 is hinged to the cross slide 11 by several hinges. Several functional springs 19 are provided between the pressure block 8 and the cross slide 11.
[0032] One side of the polishing plate 9 is hinged to the pressure block 8. Several ejector springs 20 are provided between the polishing plate 9 and the pressure block 8. The ejector springs 20 extend through the bottom surface of the pressure block 8 and into the interior of the pressure block 8. In a specific embodiment, the pressure block 8 is a wedge-shaped structure. The thick end is hinged to the cross slide 11 by a stainless steel hinge. Several functional springs 19 are arranged obliquely between the two. The front end of the polishing plate 9 is connected to the pressure block 8 by a hinge shaft 22, and the end abuts against the back of the polishing plate 9. When the plate enters, the ejector springs 20 push the polishing plate 9 down to contact the workpiece surface. When the thickness changes abruptly, the functional springs 19 allow the wedge-shaped structure to deflect around the hinge. At the same time, the ejector springs 20 extend and retract to compensate for the deformation and maintain a constant polishing pressure.
[0033] The pressure block 8 has a moving groove 21 on its side, and a rotating buckle 22 is provided on the moving groove 21. One end of the rotating buckle 22 is provided with a locking pin 23 that cooperates with the moving groove 21, and the other end is connected to the polishing plate 9 through a rotating pin 24.
[0034] The pressure block 8 has a guide lip plate 25 on the side near the feed inlet. The guide lip plate 25 is inclined upward along the horizontal line. The inclination angle of the guide lip plate 25 and the slope angle of the pressure block form a continuous transition. In a specific embodiment, a moving groove 21 is opened on the side of the pressure block 8. The rotating buckle 22 slides in the moving groove 21 through the locking pin 23. The rotating pin 24 connects the other end of the rotating buckle 22 to the polishing plate 9. The guide lip plate 25 is welded to the feed end of the pressure block 8 and is inclined upward. When replacing or adjusting the polishing plate 9, the locking pin 23 is released, and the rotating buckle 22 slides along the moving groove 21, causing the polishing plate 9 to flip outward. The maximum rotation stroke of the polishing plate 9 can be controlled. The inclination angle design of the guide lip plate 25 allows the plate to be smoothly introduced and avoids jamming at the front end.
[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
