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 drying device. Background Technology

[0002] Polishing cloth wheels are polishing tools made of cloth. They remove rough parts from the surface of a workpiece through high-speed friction, thereby improving the smoothness and gloss of the workpiece surface.

[0003] The manufacturing process of polishing cloth wheels includes steps such as applying adhesive to the cloth, winding and core loading, drying, and cutting into shape. Drying refers to winding the adhesive-coated cloth into a cylinder and then placing the cylinder into a dryer for drying.

[0004] The existing drying method involves fixing one end of a cylindrical cloth wheel spindle with a hook, then vertically placing it into the dryer for drying. The upper end of the hook is connected to a ring conveyor chain to achieve continuous feeding and improve work efficiency.

[0005] While this method improves work efficiency, it still has shortcomings. The cylindrical cloth wheel is suspended vertically after being coated with glue, causing the moisture at the top of the cloth wheel to flow downwards under gravity. This results in inconsistent moisture content at the top and bottom of the cloth wheel during the drying process. Consequently, the top of the cloth wheel may be completely dried while the bottom may not be fully dried. If the drying time is limited to the time required for the bottom to be fully dried, the overall drying time will be extended, wasting drying heat. Utility Model Content

[0006] To address the shortcomings of the existing technology, this utility model provides a polishing cloth wheel drying device that rotates the cloth wheel along its axis during the drying process, ensuring uniform moisture content throughout the cloth wheel and thus achieving a consistent drying effect.

[0007] In order to achieve the purpose of this utility model, the following solution is proposed: A polishing cloth wheel drying device includes a drying assembly, which includes a drying chamber. A heating element is provided on the top surface of the drying chamber. A lifting door is provided at the opening of the drying chamber. Two parallel and spaced guide rails are arranged along the length of the drying chamber. A material-carrying trolley moves along the guide rails. The material-carrying trolley includes a frame, with rollers slidably connected to the guide rails at both ends of its bottom. A first side frame and a second side frame are provided on both sides of the frame. A U-shaped seat is arrayed on the top surface of the first side frame to support one end of the cloth wheel spindle. A mounting box is provided on the top surface of the second side frame. A drive shaft is provided inside the mounting box. Worms are arrayed along the axis of the drive shaft. Each worm meshes with a worm wheel. A rotating shaft is coaxially located in the middle of the worm wheel. Both ends of the rotating shaft are rotatably connected to the two sides of the mounting box. One end of the rotating shaft passes through the mounting box and has a locking seat with an opening facing the U-shaped seat. A pressing block is arrayed in a circle around the outer periphery of the locking seat to press the outer wall of the other end of the cloth wheel spindle.

[0008] Furthermore, a connecting block is provided in the middle of the top surface of the door panel, and a guide post is provided on the top surface in the direction of the opening of the drying oven. The connecting block is slidably mounted on the guide post. A linear mechanism is provided at the upper end of the guide post. The output end of the linear mechanism is vertically downward and connected to the connecting block. Notches and grooves adapted to the cross-section of the guide rail are provided on both sides of the bottom of the door panel.

[0009] Furthermore, the horizontal part of the U-shaped seat has a semi-circular arc structure, and the axis at its center is collinear with the axis of the corresponding card seat.

[0010] Furthermore, a motor is installed at one end of the mounting box, and the motor is connected to one end of the drive shaft.

[0011] Furthermore, the outer periphery of the card holder is provided with stepped holes, the large end of which is connected to the inner wall of the card holder. The cross-section of the stepped holes is rectangular, and one end of the pressure block is inserted through the stepped holes.

[0012] Furthermore, the pressure block includes a T-shaped rod, the vertical part of which is slidably connected to the small end of the stepped hole. A pressure block is provided at the lower end of the vertical part of the T-shaped rod. A spring passes through the vertical part of the T-shaped rod. The upper end of the spring abuts against the connection between the large end and the small end of the stepped hole, and the lower end of the spring abuts against the pressure block.

[0013] Furthermore, the side of the pressure block facing the axis of the card seat has an arc-shaped structure.

[0014] Furthermore, the pressure block is made of rubber, and the end of the pressure block facing the U-shaped seat has a bevel.

[0015] The beneficial effects of this utility model are as follows: By using a worm gear to drive a worm wheel to rotate the chuck, the cloth wheel rotates along its own axis during the drying process. This prevents the lower side of the cloth wheel from having a higher moisture content than the previous one, thus ensuring uniform drying of the cloth wheel, improving the drying effect, and saving drying time.

Detailed Implementation

[0026] 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.

[0027] like Figures 1-8As shown, this embodiment provides a polishing cloth wheel drying device, including a drying component 10 and a material-carrying trolley that is movable along the length of the drying component 10.

[0028] like Figures 1-2 As shown, the drying assembly 10 includes a drying chamber 11, a door panel 12, and a guide rail 13. The drying chamber 11 has a rectangular tunnel structure. A heating element is provided on the top surface of the drying chamber 11. One end of the drying chamber 11 is closed, and the other end is open. A guide post 11 is provided vertically upward at the top of the opening. One side of the guide post 11 is flush with the surface of the opening, and a strip groove is provided on the side of the guide post 11 parallel to the opening. A linear mechanism 112 is provided on the top of the guide post 111. The linear mechanism 112 is a cylinder or a hydraulic cylinder.

[0029] The door panel 12 is located at one end of the opening of the drying chamber 11 and is used to close the drying chamber 11 during drying. A connecting block 121 is provided in the middle of the top surface of the door panel 12. One end of the connecting block 121 protrudes in the direction of the drying chamber 11, and the protruding end of the connecting block 121 is slidably connected to the strip groove of the guide post 111. The output end of the linear mechanism 112 is vertically downward connected to the top surface of the connecting block 121. The vertical height of the door panel 12 is controlled by the linear mechanism 112, thereby realizing the opening or closing of the drying chamber 11 by the door panel 12.

[0030] A set of guide rails 13 are arranged parallel to each other and spaced apart along the length of the drying box 11. One end of the guide rail 13 extends into the drying box 11 and the other end extends out of the drying box 11 by a certain length to support the material trolley 20.

[0031] To reduce heat loss during drying in the drying oven 11, notches 122 are provided at both ends of the bottom surface of the door panel 12, and the shape of the notches 122 is adapted to the shape of the cross-section of the guide rail 13.

[0032] like Figures 2-7 As shown, the material-carrying trolley 20 is used to place the cloth wheels 1 to be dried. The material-carrying trolley 20 includes a frame 21, rollers 22, a first side frame 23, a second side frame 24, a card seat 25, and a pressing block 26. The frame 21 has a rectangular frame structure, with downward protruding bosses on the left and right sides of its front and rear ends. The rollers 22 are located on the bottom surface of each boss, and two parallel and spaced rollers 22 are located under each boss. The cross-section of the guide rail 13 has an upward-opening concave structure. The axis of the rollers 22 is perpendicular to the length direction of the guide rail 13, and the rollers 22 roll in the middle recess of the concave structure of the guide rail 13.

[0033] The first side frame 23 is located on one side of the frame 21 along the length direction of the frame 21. Multiple U-shaped seats 231 with upward openings are arranged on the top surface of the first side frame 23. The two side arms of the U-shaped seats 231 are arranged parallel to the width direction of the first side frame 23. The U-shaped seats 231 are used to support and place one end of the spindle of the cloth wheel 1.

[0034] The second side frame 24 is located on the other side of the frame 21 along the length of the frame. A mounting box 241 is provided on the top surface of the second side frame 24, with its length aligned with that of the frame 21. The mounting box 241 is hollow and contains a drive shaft 242. Both ends of the drive shaft 242 are rotatably engaged with both ends of the mounting box 241. One end of the drive shaft 242 extends out of one end of the mounting box 241 and is connected to a motor 246. The motor 246 runs along the axis of the drive shaft 242. The centerline direction array is provided with multiple worm gears 243, the number of which is the same as the number of U-shaped seats 231. Each worm gear 243 meshes with a worm wheel 244. A rotating shaft 245 is provided coaxially along the axis of the worm wheel 244. The axis of the rotating shaft 245 is perpendicular to the length direction of the mounting box 241, and both ends of the rotating shaft 245 are rotatably engaged with the two sides of the mounting box 241 respectively. One end of the rotating shaft 245 extends out of the mounting box 241 facing the U-shaped seat 231 and is connected to the card holder 25.

[0035] The card holder 25 is coaxially located at one end of the rotating shaft 245 that extends out of the mounting box 241. The side of the card holder 25 connected to the rotating shaft 245 is closed. The end of the card holder 25 with an opening faces the U-shaped seat 231 and corresponds one to one with the U-shaped seat 231. It is used to support and place the other end of the cloth wheel 1, so that when the card holder 25 rotates, it drives the cloth wheel 1 to rotate, so that the cloth wheel 1 is heated evenly, improving drying efficiency and drying effect.

[0036] The pressing blocks 26 are arranged in an array along the circumferential direction of the card holder 25, and one end of the pressing block 26 extends into the card holder 25 to press the outer wall of the core shaft of the cloth wheel 1, thereby increasing the friction between the card holder 25 and the core shaft of the cloth wheel 1, ensuring that each cloth wheel 1 can rotate with the corresponding card holder 25, thereby improving the drying efficiency of the cloth wheel 1.

[0037] The bottom of the U-shaped seat 231 has an arc structure, and its axis is collinear with the axis of the card seat 25 so that the two ends of the mandrel of the cloth wheel 1 are kept on the same horizontal plane when it is placed, so as to avoid one end of the cloth wheel 1 abutting against the inner wall of the first side frame 23 and affecting the shape of the cloth wheel 1.

[0038] like Figures 6-8As shown, to facilitate the insertion of the cloth wheel 1 and increase the transmission efficiency of the cloth wheel 1 when the card holder 25 rotates, multiple stepped holes 251 are arranged in an array along the circumference of the card holder 25. The large end of the stepped hole 251 is connected to the inner wall of the card holder 25, and the lower end is connected to the outer wall of the card holder 25. The pressure block 26 includes a T-shaped rod 261, a pressure block 262, a spring 263, and an inclined surface 264. The vertical part of the T-shaped rod 261 is coaxially arranged in the stepped hole 251, and the vertical part of the T-shaped rod 261 is... The small end of the T-shaped rod 261 is slidably connected to the stepped hole 251. The lower end of the vertical part of the T-shaped rod 261 passes through the stepped hole 251 and is connected to the pressure block 262. The spring 263 passes through the vertical part of the T-shaped rod 261. The upper end of the spring 263 abuts against the surface at the connection between the large end and the small end of the stepped hole 251, and the lower end of the spring 263 abuts against the surface at the connection between the pressure block 262 and the T-shaped rod 261, so as to improve the stability of the spring 263 when it extends and retracts, thereby extending its service life.

[0039] Preferably, in order to increase the contact area and friction between the pressure block 262 and the spindle of the cloth wheel 1, the pressure block 262 is made of rubber material, and the side of the pressure block 262 facing the axis of the card seat 25 is set as an arc surface structure.

[0040] In a further preferred embodiment, to facilitate the insertion of the mandrel of the cloth wheel 1 into the card holder 25, the end of the pressure block 262 facing the U-shaped seat 231 is set as an inclined surface 264, and the inclined surface 264 is inclined inward into the card holder 25.

[0041] Specific operating procedures: Move the material-carrying trolley 20 outside the drying chamber 11, insert one end of the cloth wheel 1 mandrel to be dried along the opening direction of the card seat 25, so that the cloth wheel 1 mandrel enters the outer wall of the card seat 25 and is pressed by each pressure block 262, and then put the other end of the cloth wheel 1 mandrel into the corresponding U-shaped seat 231. Repeat this process so that each card seat 25 and the corresponding U-shaped seat 231 contains the cloth wheel 1 mandrel to be dried.

[0042] Then, start the rollers 22 of the loading trolley 20 to allow the loading trolley 20 to enter the drying chamber 11. After the loading trolley 20 is fully inside, start the linear mechanism 112 to push the door panel 12 vertically downwards, closing the opening of the drying chamber 11. Start the motor 226 and simultaneously turn on the heating element inside the drying chamber 11, causing the motor 246 to drive the transmission shaft 242 to rotate, which in turn drives the worm gear 243 on it to rotate. The worm gear 243 then drives the corresponding worm wheel 244 to rotate, thereby driving the card holder 25 to rotate. This causes the card holder 25 to drive the spindle of the cloth wheel 1 to rotate, so that each of the cloth wheels 1 with drying is dried evenly, improving the drying effect.

[0043] 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.
