Description

Technical Field

[0001] This utility model relates to the technical field of leveling units, and in particular to a leveling machine that is easy to clean. Background Technology

[0002] Before being stamped, sheet metal is often stored in rolls to reduce space occupancy. Therefore, pre-treatment work is usually carried out before stamping, which generally includes uncoiling, leveling and length setting. After processing, it is then transported to the punch press.

[0003] Currently, the leveling process is usually completed using a leveling machine. When the leveling machine is working, the leveling rollers gradually accumulate various dirt, oil stains, and other impurities as they level different types of boards. These contaminants not only affect the surface accuracy of the leveling rollers, causing the boards to become contaminated and affecting the leveling effect, but also increase the friction between the leveling rollers and the boards, accelerating the wear of the leveling rollers and shortening their service life. Therefore, it is often necessary to clean the surface of the leveling rollers.

[0004] Currently, cleaning leveling rollers mainly relies on manual water rinsing. Operators need to stop the leveling machine, climb onto the equipment, and use water hoses to rinse each roller individually, even wiping and brushing them. This method is not only cumbersome and time-consuming, but also wastes a lot of water resources during the rinsing process, with large amounts of water flowing down the equipment to the ground, resulting in unnecessary water consumption. Furthermore, manual rinsing is slow, difficult to control in terms of quality, and may pose safety hazards to personnel and equipment.

[0005] In view of this, it is necessary to provide a leveling machine with an automated cleaning and leveling roller that is water-saving and has a safe cleaning structure. Utility Model Content

[0022] To provide a more detailed description of this utility model, the following description is provided in conjunction with the accompanying drawings. It should be noted that the embodiments described below are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0023] refer to Figure 1 As shown, a leveling machine that is easy to clean includes a frame 1, on which a cleaning mechanism 2, a feeding and clamping mechanism 3 and a leveling mechanism 4 are arranged sequentially along the length of the frame 1.

[0024] Specifically, refer to Figure 1 and Figure 2 As shown, the cleaning mechanism 2 includes a first mounting bracket 21 disposed on the frame 1, a threaded transmission rod 22 rotatably mounted on the first mounting bracket 21, and a first driving mechanism 23. A sleeve 24 is sleeved on the threaded transmission rod 22, and the internal thread of the sleeve 24 is threadedly matched with the external thread of the threaded transmission rod 22, so that the sleeve 24 and the threaded transmission rod 22 are threadedly rotatably connected.

[0025] A clamping member 25 is provided on one side of the sleeve 24, and the clamping member 25 is used to clamp the end of a felt 5.

[0026] The clamping member 25 includes an upper clamping plate 251 and a lower clamping plate 252 fixedly disposed on the outer surface of the sleeve 24. A clamping groove 253 is formed between the upper clamping plate 251 and the lower clamping plate 252, and a fixing structure is provided on the upper clamping plate 251. One end of the felt 5 is placed in the clamping groove 253 and fixed by the fixing structure.

[0027] In this embodiment, the fixing structure includes at least one first screw hole (not shown in the figure) provided on the upper clamping plate 251 and a clamping screw 254 that matches the first screw hole. The clamping screw 254 passes through the first screw hole and is threadedly connected to the first screw hole. A clamping pad 255 is provided at one end of the clamping screw 254 located in the clamping groove 253.

[0028] When the felt 5 needs to be installed for cleaning, one end of the felt 5 can be placed in the clamping groove 253, and then the clamping screw 25 can be tightened and rotated so that it engages with the thread of the first screw hole, while the clamping pad 244 gradually approaches the felt 5 until the clamping pad 255 is in tight contact with the surface of the felt 5. At this time, the end of the felt 5 is limited and fixed in the clamping groove 253.

[0029] One end of the first driving mechanism 23 is connected to the threaded transmission rod 22, and the first driving mechanism 23 is used to drive the threaded transmission rod 22 to rotate in the forward or reverse direction, thereby driving the sleeve 24 to move back and forth along the length direction of the threaded transmission rod 22. The internal thread of the sleeve 24 matches the external thread of the threaded transmission rod 22, so that the sleeve 24 and the threaded transmission rod 22 are threadedly rotatably connected. Therefore, when the threaded transmission rod 22 rotates in the forward or reverse direction, the sleeve 24 can move back and forth along the length direction of the threaded transmission rod 22, thereby driving the end of the felt 5 held by the clamping member 25 to move.

[0030] In this embodiment, the first drive mechanism 23 is a motor, the output shaft of which is connected to one end of the threaded transmission rod 22, and the motor drives the threaded transmission rod 22 to rotate in the forward or reverse direction.

[0031] The feeding and clamping mechanism 3 includes a second mounting frame 31 mounted on the frame 1, and a pressure guide roller 32 and a first conveying roller 33 respectively rotatably mounted on the second mounting frame 31. The pressure guide roller 32 is located directly above the first conveying roller 33, and a feeding and conveying channel 34 is formed between the pressure guide roller 32 and the first conveying roller 33. In actual use, the bottom surface of the threaded transmission rod 22 is higher than the top surface of the first conveying roller 33 to avoid affecting the feeding of the first conveying roller 33.

[0032] The sheet material is fed and conveyed through the feeding and conveying channel 34. The first conveying roller 33 rotates to drive the sheet material above it forward, and the pressure guide roller 32 provides vertical downward pressure, thereby eliminating the risk of the sheet material sliding within the feeding and conveying channel 34. In actual use, a feeding platform can be set on the feeding side of the first conveying roller 33 to facilitate the feeding of the sheet material.

[0033] The second mounting frame 31 includes a fixed frame 311 symmetrically arranged in the width direction of the frame. Each fixed frame 311 has a fixed bearing seat 312 at its lower part. The two ends of the first conveying roller 33 are respectively rotatably mounted on the corresponding fixed bearing seats 312. The two inner sides of the upper part of the fixed frame 311 are symmetrically provided with sliding rails 313. A movable bearing seat 314 is slidably connected between the two sliding rails 313. The two ends of the pressure guide roller 312 are respectively rotatably mounted on the movable bearing seat 314. The top of the fixed frame 311 is provided with an adjustment component. The adjustment component is used to drive the movable bearing seat 314 to move up and down along the sliding rails 313, thereby adjusting the distance between the pressure guide roller 312 and the first conveying roller 33 to adapt to the conveying requirements of plates of different thicknesses.

[0034] In this embodiment, the adjusting assembly includes a turntable 315 and an adjusting screw 316. A second screw hole is formed at the top of the fixed frame 311. One end of the adjusting screw 316 is connected to the turntable 315, and the other end passes through the second screw hole and is connected to the movable bearing seat 314. By rotating the turntable 315, the adjusting screw 316 moves up or down, thereby causing the movable bearing seat 314 to move up and down along the sliding track 313, thus adjusting the distance between the pressure guide roller 312 and the first conveying roller 33.

[0035] In some embodiments, a third mounting bracket 6 is provided on one side of the second mounting bracket 31. A drive roller 61 is rotatably mounted on the third mounting bracket 6. The drive roller 61 is connected to a second drive mechanism for driving the drive roller 61 to rotate, and the outer surface of the drive roller 61 abuts against the pressure guide roller 32 for transmission. Both the pressure guide roller 32 and the drive roller 61 are provided with a wear-resistant rubber layer 7. In actual use, the distance between the drive roller 61 and the pressure guide roller 32 is adjustable to accommodate pressure guide rollers 32 of different heights.

[0036] The second drive mechanism drives the active roller 61 to rotate, which in turn drives the pressure guide roller 32 to rotate, assisting the first conveying roller 33 in clamping and conveying the plate. The wear-resistant rubber layer 7 can increase the friction between the surfaces of the pressure guide roller 32 and the active roller 61, making their contact transmission smoother. The elastic properties of the rubber can also prevent damage to the plate.

[0037] The leveling mechanism 4 includes a base 41 and a top seat 42 disposed on the frame. The top seat 42 is located directly above the base 41. An upper leveling mechanism is disposed on the top seat 42, and a lower leveling mechanism is disposed on the base 41. The upper leveling mechanism includes a plurality of upper leveling rollers 43 arranged in sequence. The lower leveling mechanism includes a plurality of lower leveling rollers 44 located below the upper leveling rollers 43. The lower leveling rollers 44 are correspondingly disposed to the upper leveling rollers 43, and a leveling channel 45 is formed between the upper leveling rollers 43 and the lower leveling rollers 44. The leveling channel 45 is correspondingly matched to the transmission channel 34. The other end of the felt 5 passes through the transmission channel 34 and the leveling channel 45 in sequence, and cleans the surfaces of the upper leveling rollers 43 and the lower leveling rollers 44.

[0038] The cleaning process of the upper leveling roller 43 and the lower leveling roller 44 is as follows: one end of the felt 5 is fixed to the clamp on the sleeve, and the other end passes through the transmission channel 34 and the leveling channel 45 in sequence, so that both sides of the felt 5 come into contact with the surfaces of the upper leveling roller 43 and the lower leveling roller 44. Then, the first driving mechanism drives the threaded transmission rod to rotate in the forward or reverse direction, which drives the sleeve to move back and forth along the length direction of the threaded transmission rod. At the same time, with the transmission of the first transmission roller 33, the pressure guide roller 32, the upper leveling roller 43 and the lower leveling roller 44, the felt 5 moves back and forth along the length direction of the threaded transmission rod 22 and is kept in the position between the transmission channel 34 and the leveling channel 45, thereby realizing automatic cleaning of the surfaces of the upper leveling roller 43 and the lower leveling roller 44, effectively improving the cleaning efficiency, the safety and stability of cleaning, and avoiding water waste.

[0039] The leveling machine also includes a discharge conveying mechanism 8 disposed on the side of the leveling mechanism 4 away from the feeding and clamping mechanism 3. The discharge conveying mechanism 8 includes a fourth mounting frame 81 disposed on the frame 1, and a second conveying roller 82 is rotatably mounted on the fourth mounting frame 81, with the conveying surface of the second conveying roller 82 and the conveying surface of the lower leveling roller 44 located on the same horizontal plane. By setting up the discharge conveying mechanism 8, the leveled board is conveyed to complete the unloading of the board.

[0040] The leveling process of the plate is as follows: the plate is conveyed through the transmission channel 34 of the feeding clamping mechanism 3 and transported to the leveling channel 45. Then, the upper leveling roller 43 and the lower leveling roller 44 apply bidirectional corrective force to the plate through opposite rotation (or differential rotation) to eliminate deformation such as bending and wavy edges of the plate. This achieves the leveling and conveying of the plate in the leveling channel 45 until the plate leaves the leveling channel 45, completing the leveling and being conveyed out by the second transmission roller 82.

[0041] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model and do not limit the utility model to the specific implementations described. Obviously, other modifications and variations can be made based on the content of this specification. The embodiments selected and specifically described in this specification are intended to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. They are not intended to limit the utility model, and any simple modifications to this utility model fall within the protection scope of this utility model.
