Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure roller mechanisms, and in particular to a floating pressure roller mechanism. Background Technology
[0002] Currently, one step in the processing and conveying of sheet materials is pressing to ensure stable, flat, and uniform transport, thereby improving processing quality and efficiency. Existing pressure roller machines use cylinders to push the rollers together, causing them to press against each other. However, cylinder pressing cannot adjust the degree of pressure between the rollers, easily leading to over-pressing.
[0003] Related technology can be found in Chinese patent application CN117961337A, which discloses a laser cutting fixture, including a frame with two mounting rods slidably mounted on it. Each mounting rod has several clamping mechanisms fixedly mounted on it. A pressure roller mechanism is slidably mounted between the two mounting rods. The pressure roller mechanism has a push block and a linkage mechanism, which is slidably connected to the pressure roller mechanism and is used to connect with a laser cutting machine. When the pressure roller mechanism slides along the mounting rods, multiple sets of upper and lower clamping plates are used to clamp and fix the sheet metal from its edge, replacing the bottom support frame. This prevents molten metal from falling onto the support frame during laser cutting, avoiding the cleaning process. The support rollers and pressure rollers can fix the sheet metal, adjust the distance between the sheet metal and the laser cutting head, improve cutting accuracy, prevent workpiece deformation after cutting, and also prevent equipment damage caused by collision between the laser cutting machine head and the workpiece.
[0004] Regarding the aforementioned technologies, the pressure roller mechanism cannot adjust its height during operation. When the surface of the board is uneven, the surface needs to be polished before the cutting operation can continue. This process requires a lot of manpower and is inconvenient to operate. Utility Model Content
[0005] To improve the ease of operation of the pressure roller mechanism, this application provides a floating pressure roller mechanism.
[0006] This application provides a floating pressure roller mechanism, which adopts the following technical solution:
[0007] A floating pressure roller mechanism includes a main support, a conveying mechanism, and a pressure roller mechanism. The conveying mechanism is located inside the main support and is used to convey the sheet material. The pressure roller mechanism is located inside the main support and above the conveying mechanism and is used to compress the sheet material. Several pressure roller mechanisms are arranged along the length of the conveying mechanism. Each pressure roller mechanism includes a roller, a cylinder, two limiting blocks, and two moving blocks. The limiting blocks and moving blocks correspond one-to-one. The two limiting blocks are located on both sides of the conveying mechanism along its length and are arranged vertically. The moving blocks are located inside the limiting blocks and are slidably connected to the limiting blocks vertically. The roller is located between the two moving blocks and is rotatably connected to the moving blocks vertically. The cylinder is sleeved on the outside of the roller and is rotatably connected to the roller. The lower end of the limiting block is provided with a threaded rod. The threaded rod passes through the limiting block and the moving block in sequence. The upper end of the threaded rod abuts against the roller. The threaded rod is slidably connected to the limiting block vertically and is threadedly connected to the moving block. An elastic element is provided on the outside of the threaded rod to apply a thrust to the moving block close to the limiting block.
[0008] By adopting the above technical solution, the bracket supports the conveying mechanism, the pressure roller mechanism squeezes the sheet material on the surface of the conveying mechanism, the sheet material drives the roller to rotate when it passes under the roller, the roller supports the roller, and when the surface of the sheet material is uneven, the roller drives the moving rod to move vertically away from the limit block. The elastic element and the threaded rod cooperate to limit the moving block. The pressure roller mechanism can automatically adjust the height according to the thickness of the sheet material, which improves the convenience of the pressure roller mechanism.
[0009] Optionally, the elastic element includes a spring and a nut. The spring is sleeved on the outside of the threaded rod and located below the limiting block. The nut is threadedly connected to the lower end of the threaded rod and is used to adjust the initial elastic force of the spring. The upper end of the spring abuts against the lower end of the limiting block, and the lower end of the spring abuts against the upper end of the nut.
[0010] By adopting the above technical solution, the position of the nut is adjusted so that the spring has a certain elastic force in the initial state, so that the moving block and the limiting block fit better. When the plate passes under the roller, the plate can be pressed better, thus improving the pressing effect of the pressure roller mechanism on the plate.
[0011] Optionally, the roller has abutting planes on both sides along its length, the abutting planes are arranged along the length of the roller, and the upper end of the threaded rod abuts against the abutting planes.
[0012] By adopting the above technical solution, the threaded rod abuts against the contact plane, which helps to reduce the probability of the roller rotating during the operation of the pressure roller mechanism and improves the stability of the pressure roller mechanism.
[0013] Optionally, the conveying mechanism includes two conveying supports and a conveyor belt. The two conveying supports are located on both sides of the main support along the width direction, and the conveying supports are horizontally arranged along the length direction of the main support. The conveyor belt is located between the two conveying supports and is horizontally arranged along the length direction of the main support.
[0014] By adopting the above technical solution, the conveyor support bracket supports the conveyor belt, thereby improving the stability of the conveyor belt conveying process.
[0015] Optionally, a rectangular block is provided at the upper end of the conveying bracket. The rectangular block is horizontally arranged along the length direction of the conveying bracket. A first sliding groove is opened at the upper end of the rectangular block along the length direction. A plurality of first sliders are provided in the first sliding groove. The first sliders slide along the length direction of the first sliding groove. The lower end of the limiting block contacts the rectangular block. A first fixing bolt is provided between the limiting block and the first slider. The first fixing bolt passes through the limiting block and is threadedly connected to the first slider. The first fixing bolt is slidably connected to the limiting block along the vertical direction.
[0016] By adopting the above technical solution, rotating the first fixing bolt clears the pressure between the limiting block and the rectangular block, allowing the limiting block to slide along the length of the first sliding groove. Rotating the first fixing bolt in the opposite direction makes the limiting block and the rectangular block fit tightly together, thus fixing the limiting block. This helps to improve the ease of operation of the pressure roller mechanism.
[0017] Optionally, a connecting plate is fixed at the upper end of the conveying bracket. The connecting plate is located between the conveying bracket and the rectangular block. A second sliding groove is provided along the length direction on the side of the rectangular block near the connecting plate. A plurality of second sliders are provided in the second sliding groove. The second sliders slide along the length direction of the second sliding groove. A second fixing bolt is provided between the connecting plate and the second slider. The second fixing bolt passes through the connecting plate and is threadedly connected to the second slider. The second fixing bolt is slidably connected to the connecting plate.
[0018] By adopting the above technical solution, rotating the second fixing bolt removes the pressure between the rectangular block and the connecting plate, allowing the rectangular block to slide along the length of the connecting plate. Rotating the second fixing bolt in the opposite direction makes the rectangular block fit tightly against the connecting plate, thus fixing the rectangular block. The pressure roller mechanism can be moved as a whole by adjusting the second fixing bolt, improving the convenience of the pressure roller mechanism.
[0019] Optionally, a third fixing bolt is provided between the moving block and the limiting block. The third fixing bolt is set vertically and passes through the moving block and the limiting block in sequence. The third fixing bolt is slidably connected to the moving block and threadedly connected to the limiting block.
[0020] By adopting the above technical solution, the upper end of the third fixing bolt is rotated to leave a moving space between the third fixing bolt and the moving block. When the plate is thick, the roller drives the moving block to rise vertically, and the moving block fits with the third fixing bolt, thus limiting the movement of the moving block and improving the stability of the pressure roller mechanism during operation.
[0021] Optionally, cylinders are fixed at both ends of the outer side of the roller along the length direction. The cylinders are located between the roller and the limiting block. An annular groove is opened on the side of the cylinder near the roller. Several spheres are provided in the annular groove. The spheres are rotatably connected to the cylinder. The end of the sphere away from the cylinder is in contact with the roller.
[0022] By adopting the above technical solution, the cylinder limits the roller, which helps to reduce the probability of roller misalignment. When the roller and the sphere are in contact, the sphere rotates in the annular groove, which helps to reduce the friction between the roller and the cylinder and improves the stability of the pressure roller mechanism during operation.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. When the surface of the sheet material is uneven, the roller drives the moving rod to move vertically away from the limiting block. The elastic element and the threaded rod cooperate to limit the moving block. This pressure roller mechanism can automatically adjust the height according to the thickness of the sheet material, improving the convenience of the pressure roller mechanism.
[0025] 2. Rotate the first fixing bolt to eliminate the pressure between the limiting block and the rectangular block, so that the limiting block slides along the length of the first sliding groove. Rotate the first fixing bolt in the opposite direction to make the limiting block and the rectangular block fit tightly together and fix the limiting block. This helps to improve the convenience of the operation of the pressure roller mechanism.
[0026] 3. The cylinder limits the roller, which helps reduce the probability of roller misalignment. When the roller and the sphere are in contact, the sphere rotates in the annular groove, which helps reduce the friction between the roller and the cylinder and improves the stability of the pressure roller mechanism during operation.

Detailed Implementation
[0033] The present application will be further described in detail below with reference to all the accompanying drawings.
[0034] This application discloses a floating pressure roller mechanism. Example
[0035] Reference Figure 1 A floating pressure roller mechanism includes a main support 1 and a conveying mechanism 2. The conveying mechanism 2 is located inside the main support 1 and is used to convey the sheet material. The main support 1 is provided with a pressure roller mechanism 3, which is located above the conveying mechanism 2 and is used to limit the sheet material. Multiple pressure roller mechanisms 3 are arranged along the length of the conveying mechanism 2.
[0036] Reference Figure 2 and Figure 3 The conveying mechanism 2 includes two conveying supports 21 and a conveyor belt 22. The two conveying supports 21 are located on both sides of the main support 1 along the width direction. The conveying supports 21 are horizontally arranged along the length direction of the main support 1. The conveyor belt 22 is located between the two conveying supports 21 and supports the conveyor belt 22. A connecting plate 24 is fixedly provided at the upper end of the conveying supports 21. The connecting plate 24 is horizontally arranged along the length direction of the conveying supports 21. A rectangular block 23 is provided at the upper end of the connecting plate 24. The rectangular block 23 is horizontally arranged along the length direction of the connecting plate 24.
[0037] Reference Figure 2 and Figure 3A second sliding groove 234 is provided along the length direction of the rectangular block 23 near the connecting plate 24. Multiple second sliders 235 are provided in the second sliding groove 234. The second sliders 235 are slidably connected to the rectangular block 23 along the length direction of the second sliding groove 234. A second fixing bolt 236 is provided between the connecting plate 24 and the second slider 235. The second fixing bolt 236 passes through the connecting plate 24 and is threadedly connected to the second slider 235. The second fixing bolt 236 is slidably connected to the connecting plate 24. Rotating the second fixing bolt 236 relieves the pressure between the rectangular block 23 and the connecting plate 24, causing the rectangular block 23 to slide along the length direction of the connecting plate 24. Rotating the second fixing bolt 236 in the opposite direction makes the rectangular block 23 fit tightly against the connecting plate 24, thus fixing the rectangular block 23. The pressure roller mechanism 3 can be moved as a whole by adjusting the second fixing bolt 236, which improves the convenience of the pressure roller mechanism 3.
[0038] Reference Figure 2 and Figure 3 The upper end of the rectangular block 23 has a first sliding groove 231 along its length. The first sliding groove 231 contains a plurality of first sliders 232, which can slide along the length of the first sliding groove 231. The pressure roller mechanism 3 includes two limiting blocks 33, which are located on both sides of the conveying mechanism 2 along its length and are arranged vertically. The lower end of the limiting block 33 is in contact with the rectangular block 23. A first fixing bolt 233 is provided between the limiting block 33 and the first slider 232. The first fixing bolt 233 passes through the limiting block 33 and is threadedly connected to the first slider 232. The first fixing bolt 233 is slidably connected to the limiting block 33 vertically. Rotating the first fixing bolt 233 relieves the pressure between the limiting block 33 and the rectangular block 23, allowing the limiting block 33 to slide along the length of the first sliding groove 231. Rotating the first fixing bolt 233 in the opposite direction makes the limiting block 33 fit tightly against the rectangular block 23, thus fixing the limiting block 33. This improves the ease of operation of the pressure roller mechanism 3.
[0039] Reference Figure 1 and Figure 4The pressure roller mechanism 3 also includes a roller 31, a cylinder 32, and two moving blocks 34. A limiting block 33 and two moving blocks 34 correspond one-to-one. The moving blocks 34 are located inside the limiting block 33 and are slidably connected to the limiting block 33 vertically. The roller 31 is located between the two moving blocks 34, supporting the roller 31. The roller 31 is rotatably connected to the moving blocks 34 vertically. The cylinder 32 is sleeved on the outside of the roller 31, and the roller 31 is rotatably connected to the cylinder 32. The limiting block 31... The lower end of the roller 3 is provided with a threaded rod 35, which passes through the limiting block 33 and the moving block 34 in sequence. The upper end of the threaded rod 35 abuts against the roller 31. The threaded rod 35 can drive the moving block 34 to move up and down vertically. The roller 31 has abutting planes on both sides along its length. The abutting planes are set along the length of the roller 31. The upper end of the threaded rod 35 abuts against the abutting planes, which helps to reduce the probability of the roller 31 rotating when the pressure roller mechanism 3 is working and improves the stability of the pressure roller mechanism 3.
[0040] Reference Figure 4 An elastic element 36 is provided on the outer side of the threaded rod 35. The elastic element 36 is used to limit the movement block 34. The elastic element 36 includes a spring 361 and a nut 362. The spring 361 is sleeved on the outer side of the threaded rod 35 and located below the limiting block 33. The nut 362 is threadedly connected to the lower end of the threaded rod 35. The upper end of the spring 361 abuts against the lower end of the limiting block 33, and the lower end of the spring 361 abuts against the upper end of the nut 362. By adjusting the position of the nut 362, the spring 361 has a certain elastic force in the initial state, so that the movement block 34 and the limiting block 33 fit better. When the plate passes under the roller 32, it can better press the plate and improve the pressing effect of the pressure roller mechanism 3 on the plate.
[0041] Reference Figure 4 A third fixing bolt 341 is provided between the moving block 34 and the limiting block 33. The third fixing bolt 341 is set vertically and passes through the moving block 34 and the limiting block 33 in sequence. The third fixing bolt 341 is slidably connected to the moving block 34, and the moving block 34 can slide vertically outside the third fixing bolt 341. The third fixing bolt 341 is threadedly connected to the limiting block 33. By rotating the third fixing bolt 341, a moving space is left between the upper end of the third fixing bolt 341 and the moving block 34. When the surface of the plate is uneven, the roller 31 drives the moving block 34 to rise vertically. The moving block 34 fits with the third fixing bolt 341, which limits the movement of the moving block 34 and improves the stability of the pressure roller mechanism 3 during operation.
[0042] Reference Figure 4 and Figure 5Both ends of the roller 31 along its length are fixed with cylinders 311. The cylinders 311 are located between the roller 32 and the limiting block 33. The cylinders 311 limit the roller 32, which helps to reduce the probability of axial displacement of the roller 32. The side of the cylinder 311 closest to the roller has an annular groove 312. Multiple balls 313 are provided in the annular groove 312. The balls 313 are rotatably connected to the cylinder 311. The end of the ball 313 away from the cylinder 311 is in contact with the roller 32. When the roller 32 is in contact with the ball 313, the ball 313 rotates in the annular groove 312, which helps to reduce the friction between the roller 32 and the cylinder 311 and improves the stability of the working process of the pressure roller mechanism 3.
[0043] The implementation principle of a floating pressure roller mechanism in this application embodiment is as follows: When the plate is thick, the roller 31 drives the moving rod to move vertically away from the limiting block 33. The spring 361 and the threaded rod 35 cooperate to limit the moving block 34. The spring 361 and the nut 362 cooperate to give the spring 361 a certain elastic force in the initial state. Rotating the second fixing bolt 236 eliminates the pressure between the rectangular block 23 and the connecting plate 24, causing the rectangular block 23 to slide along the length direction of the connecting plate 24. Rotating the second fixing bolt 236 in the opposite direction makes the rectangular block 23 fit tightly against the connecting plate 24, fixing the rectangular block 23. Rotating the first fixing bolt... Bolt 233 eliminates the pressure between the limiting block 33 and the rectangular block 23, allowing the limiting block 33 to slide along the length of the first sliding groove 231. The first fixing bolt 233 is rotated in the opposite direction to make the limiting block 33 and the rectangular block 23 fit tightly together. By rotating the third fixing bolt 341, a moving space is left between the upper end of the third fixing bolt 341 and the moving block 34. When the surface of the plate is uneven, the roller 31 drives the moving block 34 to rise vertically. The moving block 34 fits with the third fixing bolt 341, limiting the movement of the moving block 34. This pressure roller mechanism 3 can automatically adjust its height according to the height of the plate, improving the convenience of the operation of the pressure roller mechanism 3.
[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
