Description

Technical Field

[0001] This utility model relates to the field of wool wheel processing technology, specifically to an automatic edge trimming mechanism applied to wool wheels. Background Technology

[0002] Wool wheels are polishing and abrasive materials made of high-density wool fibers. They are mainly divided into two categories: rolled wool wheels and pure wool wheels. They are used in conjunction with polishing powder and coolant to polish and repair the surfaces of materials such as glass, ceramics, stone, and metal. They are especially used as the final tool in glass processing to eliminate shallow scratches and improve gloss.

[0003] In existing technology, since the edges of wool wheels need to be cut off, they were previously ground manually using grinding wheels. This resulted in high repetitive work for employees at this machine position, high labor intensity, and low production efficiency, which was detrimental to the positive development of the enterprise. Therefore, it is necessary to develop new equipment to reduce the labor intensity of employees, improve production efficiency, and control the enterprise's costs. The existing manual grinding method has the following drawbacks: 1. Manual grinding will result in large deviations in the dimensions of the cut edges of the product, and the cut edges of the ground product will be uneven, causing product quality problems.

[0004] 2. Manual grinding can produce about 128 products per day, which is time-consuming, labor-intensive, dangerous, and has a high labor intensity.

[0005] Therefore, an automatic trimming mechanism for wool wheels is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an automatic edge-cutting mechanism for wool wheels, in order to solve the problem that manual grinding will cause large deviations in the edge dimensions of the product, resulting in uneven edges and reduced product quality.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic trimming mechanism for wool wheels, comprising a frame, a wool wheel body, and a housing fixedly connected to the top of the frame, wherein a power box is fixedly installed on the outside of one side of the housing; Both sides of the box are hinged with side doors, and a cover plate is vertically slidably installed on one side of the front of the box; Also includes: The top of the frame is provided with a cutting edge assembly, and one side of the front of the housing is provided with a placement assembly; The edge-cutting assembly includes a horizontal plate fixedly connected to the top of the frame, a drive motor fixedly installed at the bottom of the horizontal plate, a lead screw rotatably connected to the top of the horizontal plate, a belt drive unit between the output end of the drive motor and the lead screw, a sliding seat threaded to the outer side of the lead screw, an edge-cutting motor fixedly installed at the top of the sliding seat, and a cutter fixedly connected to the output end of the edge-cutting motor. The placement assembly includes a placement plate fixedly connected to one side of the front of the box. A servo motor is fixedly installed on one side of the inner wall of the box. A turntable is rotatably connected to the middle of the interior of the placement plate. A belt drive unit is connected between the output end of the servo motor and the turntable. A limit block is slidably installed on the top of the placement plate.

[0008] Preferably, the drive motor drives the lead screw to rotate via a belt drive, and two slide rails are fixedly connected in parallel to the top of the horizontal plate.

[0009] Preferably, the lead screw is slidably connected to the slide rail, and the trimming motor is connected to the sliding seat via a rotating shaft, with bolts installed on the outer side of the rotating shaft.

[0010] Preferably, the servo motor drives the turntable to rotate via the belt drive unit 2. The turntable is vertically arranged. A vertical plate is fixedly connected to the top of the placement plate. Three vertical plates are provided, including one front and two side plates. A sliding rod is slidably connected inside the vertical plate. One end of the sliding rod is fixedly connected to a limiting block.

[0011] Preferably, the number of limiting blocks is the same as that of the vertical plate, and a spring is sleeved on the outside of the slide rod. One end of the spring is fixedly connected to the vertical plate, and the other end of the spring is fixedly connected to the end of the slide rod.

[0012] Preferably, two mounting plates are fixedly connected to the top of the placement plate. A screw is rotatably connected to one side of the front of the mounting plate, and the two screws are threaded to the same U-shaped plate on their outer sides. The inner walls of the U-shaped plate are provided with inclined surfaces on both sides.

[0013] Preferably, a cylinder is fixedly installed on the inner top surface of the housing, and a pressure plate is rotatably connected to the bottom of the telescopic end of the cylinder. A switch control box is fixedly installed in the middle of the other side of the housing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting the edge-cutting component and the placement component, three limiting blocks push and limit the wool wheel body, maintaining the coaxial state of the wool wheel body and the turntable, reducing the positioning offset of the wool wheel body, and the turntable drives the wool wheel body to rotate, which facilitates the uniform edge-cutting treatment of the outer ring of the wool wheel body. The specific details are as follows: By setting up the trimming and placement components, after the operator presses and positions the wool wheel body, they start the drive motor through the switch control box. The drive motor drives the lead screw to rotate through the belt drive unit one. The rotation of the lead screw causes the sliding seat to move. The sliding seat slides on the outside of the slide rail. The sliding seat also drives the trimming motor to move. When the trimming motor moves to the position of the wool wheel body, the operator starts the trimming motor and servo motor through the switch control box. The trimming motor drives the cutter to rotate. The cutter performs trimming processing on the wool wheel body. Meanwhile, the servo motor drives the turntable to rotate through the belt drive unit two. The turntable drives the wool wheel body to rotate, which facilitates uniform trimming processing on the outer ring of the wool wheel body. This solves the problem that manual grinding will cause large deviations in the product trimming dimensions and uneven trimming edges, which reduces product quality. By setting up the placement components, the operator places the wool wheel body on top of the turntable, then turns two screws. The screws rotate, causing the U-shaped plate to move. The center of the U-shaped plate presses against the sliding rod on the front, and the inclined surfaces on both sides of the limiting block press against the sliding rod on both sides, so that the sliding rods are all compressed. The sliding rods compress the springs and drive the limiting blocks to move, so that the three limiting blocks push and limit the wool wheel body, keeping the wool wheel body and the turntable coaxial, reducing the positioning offset of the wool wheel body, and facilitating subsequent precise edge cutting. After the wool wheel body is positioned, the cylinder is started through the switch control box. The cylinder drives the pressure plate to descend, pressing the pressure plate tightly against the top of the wool wheel body. The pressure plate and the cylinder are rotated and installed, so they will not affect the subsequent rotation of the wool wheel body. At this time, the screws are reversed, causing the limiting blocks to separate from the wool wheel body, without affecting the edge cutting processing of the wool wheel body.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1 - Figure 7 The present invention provides a technical solution: an automatic trimming mechanism for wool wheels, comprising a frame 1, a wool wheel body 8, and a box 2 fixedly connected to the top of the frame 1. The box 2 serves as a support and bearing unit, and a power box 3 is fixedly installed on the outside of one side of the box 2.

[0019] Both sides of the box 2 are hinged with side doors 4, and a cover plate 5 is vertically slidably installed on one side of the front of the box 2.

[0020] The top of the frame 1 is provided with a cutting assembly 6. The cutting assembly 6 includes a horizontal plate 61 fixedly connected to the top of the frame 1. A drive motor 62 is fixedly installed at the bottom of the horizontal plate 61. A lead screw 65 is rotatably connected to the top of the horizontal plate 61. A belt drive part 63 is provided between the output end of the drive motor 62 and the lead screw 65. A sliding seat 66 is threadedly connected to the outside of the lead screw 65. A cutting motor 67 is fixedly installed at the top of the sliding seat 66. A cutter 68 is fixedly connected to the output end of the cutting motor 67.

[0021] The drive motor 62 drives the lead screw 65 to rotate through the belt drive unit 63, and two slide rails 64 are fixedly connected to the top of the horizontal plate 61 in parallel.

[0022] The lead screw 65 is slidably connected to the slide rail 64. The cutting motor 67 is connected to the sliding seat 66 through a rotating shaft, and a bolt is installed on the outside of the rotating shaft. By loosening the bolt, the angle of the cutting motor 67 is adjusted, and the cutting motor 67 drives the rotating shaft to rotate. After adjustment, the bolt is tightened to fix the rotating shaft, which facilitates the adjustment of the cutting angle.

[0023] After the operator clamps and positions the wool wheel body 8, they start the drive motor 62 via the switch control box 11. The drive motor 62 drives the lead screw 65 to rotate via the belt drive part 63. The rotation of the lead screw 65 causes the sliding seat 66 to move. The sliding seat 66 slides on the outside of the slide rail 64. The sliding seat 66 also drives the trimming motor 67 to move. When the trimming motor 67 moves to the position of the wool wheel body 8, the operator starts the trimming motor 67 and the servo motor 72 via the switch control box 11. The trimming motor 67 drives the cutter 68 to rotate, and the cutter 68 trims the wool wheel body 8.

[0024] A placement component 7 is provided on one side of the front of the housing 2. The placement component 7 includes a placement plate 71 fixedly connected to one side of the front of the housing 2. A servo motor 72 is fixedly installed on one side of the inner wall of the housing 2. A turntable 74 is rotatably connected to the middle of the interior of the placement plate 71. A belt drive part 73 is connected between the output end of the servo motor 72 and the turntable 74. A limit block 77 is slidably installed on the top of the placement plate 71.

[0025] Servo motor 72 drives turntable 74 to rotate via belt drive unit 2 73. Turntable 74 is vertically arranged. Vertical plate 75 is fixedly connected to the top of placement plate 71. There are three vertical plates 75, including one front and two sides. Sliding rod 76 is slidably connected inside vertical plate 75. One end of sliding rod 76 is fixedly connected to limit block 77.

[0026] The number of limiting blocks 77 is the same as that of the vertical plate 75. A spring 78 is sleeved on the outside of the slide rod 76. One end of the spring 78 is fixedly connected to the vertical plate 75, and the other end of the spring 78 is fixedly connected to the end of the slide rod 76.

[0027] Two mounting plates 79 are fixedly connected to the top of the placement plate 71. A screw 710 is rotatably connected to one side of the front of the mounting plate 79. The two screws 710 are threaded to the same U-shaped plate 711 on their outer sides. The inner walls of the U-shaped plate 711 are provided with inclined surfaces on both sides.

[0028] A cylinder 9 is fixedly installed on the inner top surface of the housing 2. A pressure plate 10 is rotatably connected to the bottom of the telescopic end of the cylinder 9. A switch control box 11 is fixedly installed in the middle of the other side of the housing 2.

[0029] The operator places the wool wheel body 8 on top of the turntable 74, then turns the two screws 710. The rotation of the screws 710 causes the U-shaped plate 711 to move. The middle of the U-shaped plate 711 presses against the front slide bar 76, and the two inclined surfaces of the limiting block 77 press against the slide bars 76 on both sides, so that the slide bars 76 are all compressed. The slide bars 76 compress the spring 78 and drive the limiting block 77 to move, so that the three limiting blocks 77 push and limit the wool wheel body 8, keeping the wool wheel body 8 and the turntable 74 coaxial, reducing the positioning offset of the wool wheel body 8, and facilitating subsequent precise edge cutting.

[0030] After positioning the wool wheel body 8, the cylinder 9 is activated by the switch control box 11. The cylinder 9 drives the pressure plate 10 to descend, and the pressure plate 10 presses against the top of the wool wheel body 8. The pressure plate 10 and the cylinder 9 are rotatably installed and will not affect the subsequent rotation of the wool wheel body 8. At this time, the reverse screw 710 separates the limit block 77 from the wool wheel body 8, which will not affect the edge cutting of the wool wheel body 8. The servo motor 72 drives the turntable 74 to rotate through the belt drive part 73. The turntable 74 drives the wool wheel body 8 to rotate, which facilitates the uniform edge cutting of the outer ring of the wool wheel body 8.

[0031] Working principle: Before using this automatic trimming mechanism for wool wheels, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 7As shown, the operator places the wool wheel body 8 on top of the turntable 74, then turns the two screws 710. The screws 710 rotate, causing the U-shaped plate 711 to move. The middle of the U-shaped plate 711 presses against the sliding rod 76 on the front, and the inclined surfaces on both sides of the limiting block 77 press against the sliding rods 76 on both sides, so that the sliding rods 76 are all compressed. The sliding rods 76 compress the spring 78 and drive the limiting block 77 to move, so that the three limiting blocks 77 push and limit the wool wheel body 8, keeping the wool wheel body 8 and the turntable 74 coaxial, reducing the positioning offset of the wool wheel body 8, and facilitating subsequent precise edge cutting. After the wool wheel body 8 is positioned, the cylinder 9 is started through the switch control box 11. The cylinder 9 drives the pressure plate 10 to descend, and the pressure plate 10 presses against the top of the wool wheel body 8. The pressure plate 10 and the cylinder 9 are rotated and installed without affecting the wool wheel body. 8. During subsequent rotation, the reverse screw 710 separates the limit block 77 from the wool wheel body 8. The drive motor 62 is started via the switch control box 11. The drive motor 62 drives the lead screw 65 to rotate via the belt drive part 1 63. The rotation of the lead screw 65 causes the sliding seat 66 to move. The sliding seat 66 slides on the outside of the slide rail 64. The sliding seat 66 also drives the trimming motor 67 to move. When the trimming motor 67 moves to the position of the wool wheel body 8, the operator starts the trimming motor 67 and the servo motor 72 via the switch control box 11. The trimming motor 67 drives the cutter 68 to rotate. The cutter 68 trims the wool wheel body 8. The servo motor 72 drives the turntable 74 to rotate via the belt drive part 2 73. The turntable 74 drives the wool wheel body 8 to rotate, which facilitates the uniform trimming of the outer ring of the wool wheel body 8.
