Description

Technical Field

[0001] This utility model belongs to the technical field of polishing cloth wheel processing equipment, and in particular relates to a polishing cloth wheel wood board bonding device. Background Technology

[0002] The polishing cloth wheel processing technology includes winding, drying, tightening, cutting, and gluing wooden boards. Among them, gluing the template involves coating one side of a cut disc-shaped wooden board with white latex and gluing it to the side of the cloth wheel to improve the strength of the cloth wheel.

[0003] The existing method of bonding polishing wheels to wooden boards involves applying white glue to one side of the wooden board, then placing the polishing wheel into the board with the glued side facing up. Finally, the bonded polishing wheel is placed into a turntable, and a roller is attached to the outer circumference of the turntable. The turntable is then started to rotate, causing the roller to move closer to the outer circumference of the polishing wheel, thereby calibrating the coaxiality of the polishing wheel and the wooden board. After the coaxiality calibration is completed, the polishing wheel and the wooden board are removed and placed into the production line. A vertically downward pressing device is installed in the conveying direction of the production line, so that the output end of the pressing device presses the top surface of the polishing wheel vertically downward to make the wooden board and the polishing wheel bond more firmly.

[0004] While this method can improve the adhesion between the polishing wheel and the wood board to some extent, the hammering process causes uneven force on the polishing wheel and fails to completely cover the surface where the polishing wheel and the wood board are bonded. Therefore, the adhesion between the polishing wheel and the wood board still needs to be improved. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a polishing cloth wheel and wood board bonding device. When bonding the polishing cloth wheel and the wood board, the coaxiality of the polishing cloth wheel and the wood board is checked, and the top surface of the polishing cloth wheel is pressed simultaneously to improve the bonding effect between the polishing cloth wheel and the wood board.

[0006] While bonding the polishing cloth wheel to the wooden board, ensure the coaxiality of the polishing cloth wheel and the wooden board to improve work efficiency.

[0007] In order to achieve the purpose of this utility model, the following solution is proposed: A polishing cloth wheel wood board bonding device includes a conveying component, a positioning component, and a pressing component. The conveying component includes an operating table with two mutually perpendicular first and second conveyor belts. A receiving groove is recessed at the intersection of the first and second conveyor belts. A hidden hole is recessed in the inner wall of the first conveyor belt on the side away from the second conveyor belt. A push-out component with the output direction consistent with the conveying direction of the second conveyor belt is provided in the hidden hole. The positioning component includes a tray coaxially disposed in a receiving groove, a telescopic rod coaxially disposed at the bottom of the tray and rotatably disposed about its own axis, and clamping members arranged in a circular array around the outer periphery of the tray. One end of the clamping member is vertically slidably connected to the tray, and the other end is rotatably provided with a claw for clamping the outer wall of the polishing cloth wheel. The pressing assembly includes a vertically positioned lifting rod located on one side of the receiving groove and corresponding to the conveying direction of the first conveyor belt. The upper end of the lifting rod is provided with a cantilever, and a vertically positioned inverted T-shaped mounting rod is provided below the cantilever. The lower end of the mounting rod is provided with a roller, the length of which is greater than the radius of the polishing cloth wheel.

[0008] Furthermore, a protruding ring is provided on the inner wall of the receiving groove protruding towards its center. A guide block is provided at the lower end of the protruding ring. The guide block is at a distance from the inner wall of the receiving groove. A first inclined surface is provided on the side of the guide block facing the inner wall of the receiving groove. The upper end of the first inclined surface faces the inner wall of the receiving groove. A second inclined surface is provided on the side of the upper end of the gripper facing the tray. The inclination of the second inclined surface is adapted to the inclination of the first inclined surface.

[0009] Furthermore, the ejector includes a cylinder with an output push plate whose dimensions are adapted to the inner wall shape of the concealed hole.

[0010] Furthermore, the outer periphery of the tray is provided with grooves arranged in a circular array, and guide rods are vertically arranged in the grooves. Springs are sleeved on the guide rods. The clamping component includes a slide block. One end of the slide block passes through the guide rod and is slidably connected to the groove. The bottom surface of the slide block abuts against the upper end of the spring. The other end of the gripper is connected to the slide block by a torsion spring so that the upper end of the gripper fits against the outer wall of the tray.

[0011] Furthermore, the two ends of the chute are at a certain distance from the upper and lower surfaces of the tray, respectively.

[0012] Furthermore, a U-shaped groove is provided at the top of the other end of the slide, with the opening of the U-shaped groove facing the inner wall of the receiving groove, and one side of the U-shaped groove connecting to the top surface of the slide, and the lower end of the gripper is hinged in the U-shaped groove.

[0013] Furthermore, when the slide block is at the bottom of the slide groove, the distance from the top surface of the slide block to the top surface of the slide groove is less than the length of the gripper.

[0014] Furthermore, the bottom surface of the horizontal part of the mounting rod is recessed with a mounting groove, and the two ends of the roller are rotatably connected to the mounting groove.

[0015] The beneficial effects of this utility model are as follows: The polishing cloth wheel and the wooden board coated with white glue are automatically bonded together. During the bonding process, the outer periphery of the polishing cloth wheel and the wooden board are clamped synchronously by the grippers to ensure the coaxiality of the polishing cloth wheel and the wooden board. At the same time, the polishing cloth wheel and the wooden board rotate synchronously with the tray so that the roller presses on the polishing cloth wheel and covers the polishing cloth wheel, improving the bonding effect and thus improving the quality of the formed polishing cloth wheel.

Detailed Implementation

[0023] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0024] like Figures 1-5 As shown, this embodiment provides a polishing cloth wheel wood board bonding device, including a conveying component 10, a positioning component 20 and a pressing component 30. The conveying component 10 is used to place the wood board coated with white glue onto the board.

[0025] like Figure 1As shown, the conveying assembly 10 includes an operating table 11, a first conveyor belt 12, a second conveyor belt 13, and an ejector 15. The first conveyor belt 12 is used to convey the wooden board 2 coated with white glue and the polishing cloth wheel 1, and the wooden board 2 coated with white glue and the polishing cloth wheel 1 are alternately placed on the first conveyor belt 12. During conveying, the side of the wooden board 2 coated with white glue faces upward. The first conveyor belt 12 and the second conveyor belt 13 are arranged perpendicular to each other. A receiving groove 14 is recessed at the intersection of the first conveyor belt 12 and the second conveyor belt 13. The receiving groove 14 has a cylindrical structure. The positioning assembly 20 is concentrically arranged at the bottom of the receiving groove 14. When the wooden board 2 coated with white glue enters the receiving groove 11 along the first conveyor belt 12, the polishing cloth wheel 1 then enters the receiving groove 11, thereby achieving the bonding of the polishing cloth wheel 1 and the wooden board 2.

[0026] Specifically, such as Figures 2-4 As shown, to facilitate the entry of the polishing cloth wheel 1 and the wooden board 2 into the receiving groove 11, a protruding ring 141 is provided on the inner wall of the top surface of the receiving groove 14 in the direction of its axis. The diameter of the protruding ring 141 is adapted to the diameter of the wooden board 2. A guide block 142 is provided at the lower end of the protruding ring 141 facing the axis of the receiving groove 141. A first inclined surface 143 is provided on the side of the guide block 142 facing the inner wall of the receiving groove 14. The upper end of the first inclined surface 143 faces the inner wall of the receiving groove 14, and the lower end faces the side where the axis of the receiving groove 11 is located.

[0027] The ejector 15 includes a cylinder 151 and a pusher plate 152. A hidden hole 121 is recessed on the inner wall of the first conveyor belt 12 away from the second conveyor belt 13. The pusher plate 152 is disposed in the hidden hole 121, and the outer dimensions of the pusher plate 152 are adapted to the inner wall dimensions of the hidden hole 121. The cylinder 151 is installed on the outer wall of the first conveyor belt 12 away from the second conveyor belt 13. The output end of the cylinder 151 is connected to the pusher plate 152, and the output direction of the cylinder 151 is consistent with the conveying direction of the second conveyor belt 13.

[0028] like Figures 2-4 As shown, the positioning component 20 includes a tray 21, a telescopic rod 22, and a clamping member 23. The telescopic rod 22 is coaxially disposed in the receiving groove 14, and the telescopic rod 22 is rotatably disposed along its axis. Its rotation can be driven by a motor, and its extension can be achieved by a hydraulic cylinder or a pneumatic cylinder. During installation, the hydraulic cylinder or pneumatic cylinder is placed at the output end of the motor.

[0029] Specifically, in order to facilitate the synchronous rotation of the pallet 21, the wooden board 2 and the cloth wheel 1, the outer periphery of the pallet 21 is provided with a circumferential array of grooves 211. The two ends of the grooves 211 are respectively a certain distance from the upper and lower surfaces of the pallet 21. A guide rod 212 is vertically provided in the grooves 211, and a spring 213 is sleeved on the guide rod 212.

[0030] like Figures 3-4As shown, the clamping member 23 includes a gripper 231, a second inclined surface 232, and a slide 233. The slide 233 is slidably disposed in the slide groove 211. One end of the slide 233 facing the tray 21 passes through the guide rod 212. The upper end of the spring 213 is connected to the bottom surface of one end of the guide rod 212 connected to the slide 233, and the lower end of the spring 213 is connected to the bottom surface of the slide groove 211. The other end of the slide 233 extends out of the slide groove 211 and extends towards the inner wall of the receiving groove 14. The top surface of the end of the slide 233 facing the inner wall of the receiving groove 14 is provided with a U-shaped groove, and the opening of the U-shaped groove faces downward toward the inner wall of the receiving groove 14. Furthermore, the top surfaces of the two side arms of the U-shaped groove are connected to the top surface of the slide block 233. The gripper 231 is vertically arranged in the U-shaped groove, and the gripper 231 is connected to the U-shaped groove by a pin. A torsion spring is provided at the connection between the pin and the gripper 231 so that the upper end of the gripper 231 is kept in contact with the outer wall of the tray 21 under the action of the torsion spring. This facilitates the clamping of the wooden board 2 and the outer periphery of the polishing cloth wheel 1 entering the top surface of the tray 21, thereby ensuring the coaxiality of the polishing cloth wheel 1 and the wooden board 2, and better transmitting the circumferential movement of the tray 21, so that the polishing cloth wheel 1 and the wooden board 2 entering the tray 21 rotate synchronously. When the slide block 233 is at the lowest end of the slide groove 211, the distance from the top surface of the slide block 233 to the top surface of the slide groove 211 is less than the length of the gripper 231, so as to prevent the upper end of the gripper 231 from extending into the tray 21 under the action of the torsion spring.

[0031] Preferred, such as Figures 4-5 As shown, in order to facilitate the smooth entry of the wooden board 2 and the polishing cloth wheel 1 into the tray 21, the second inclined surface 232 is set on the top of the gripper 231 facing the tray 21, and the inclination of the second inclined surface 232 is adapted to the inclination of the first inclined surface 143. In use, the telescopic rod 22 moves vertically upward to make the tray 21 move vertically upward, and the top surface of the tray 21 is lower than the top surface of the first conveyor belt 12, so as to reduce the height of the wooden board 2 entering the top surface of the tray 21. At this time, the second inclined surface 232 on the gripper 231 rotates towards the inner wall of the receiving groove 14 under the obstruction of the first inclined surface 143. When the center of the wooden board 2 coincides with the center of the receiving groove tray 21, the wooden board 2 falls completely into the top surface of the tray 21. At this time, the telescopic rod 22 descends vertically so that the top surface of the wooden board 2 coated with white latex is lower than the first conveyor belt 12, so that the polishing cloth wheel 1 falls into the top surface of the wooden board 2. When the center of the polishing cloth wheel 1 coincides with the center of the wooden board 2, the polishing cloth wheel 1 falls completely into the top surface of the wooden board 2.

[0032] Then the telescopic rod 22 moves vertically downward so that the second inclined surface 232 on the top surface of the gripper 231 disengages from the first inclined surface 143, thereby allowing the gripper 231 to reset under the action of the torsion spring, thus clamping the outer periphery of the polishing cloth wheel 1 and the wooden board 2, thereby ensuring their coaxiality.

[0033] like Figures 1-2As shown, the pressing assembly 30 includes a lifting rod 31, a cantilever 32, a mounting rod 33, and a roller 34. The lifting rod 31 is vertically arranged and positioned on the outside of the receiving groove 14, corresponding to the material feeding direction of the first conveyor belt 12. The cantilever 32 is arranged parallel to the first conveyor belt 12, and one end of the cantilever 32 is vertically connected to the upper end of the lifting rod 31. The mounting rod 33 has an inverted T-shaped structure, with the upper end of its vertical part connected to the cantilever 32, and the bottom of its horizontal part recessed inward with a groove. The two ends of the roller 34 are rotatably connected to the two side walls of the groove, and the axial direction of the roller 34 is consistent with the radial direction of the receiving groove 14.

[0034] After the wooden board 2 and the polishing cloth wheel 1 are fully inserted into the receiving groove 14 and the coaxiality is calibrated under the action of the gripper 231, the lifting rod 31 is activated to move vertically downward so that the roller 34 presses the polishing cloth wheel 1 in the radial direction. The telescopic rod 22 is activated to rotate, so that the tray 21 drives the polishing cloth wheel 1 and the wooden board 2 to rotate synchronously. This causes the roller 34 to press and cover the polishing cloth wheel 1 so that the surfaces of the polishing cloth wheel 1 and the wooden board 2 in contact are all pressed, thereby improving the adhesion effect and making the polishing cloth wheel 1 and the wooden board 2 more firmly bonded.

[0035] To ensure that the roller 34 presses and completely covers the polishing cloth wheel 1, the projected length of the roller 34 on the polishing cloth wheel 1 covers the radius of the polishing cloth wheel 1.

[0036] After pressing, the lifting rod 31 moves vertically upward, thereby moving the roller 34 to a certain height above the polishing cloth wheel 1. The telescopic rod 22 stops rotating and pushes the bonded cloth wheel vertically upward out of the receiving groove 14. The cylinder 151 is activated, causing the cylinder 151 to push the push plate 152, so that the push plate 152 pushes the bonded polishing cloth wheel 1 and the wooden board 2 onto the second conveyor belt 13, thereby allowing the second conveyor belt 13 to output the bonded polishing cloth wheel 1 and the wooden board 2.

[0037] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
