Description

Technical Field

[0001] This application relates to the field of back rubbing machines, and more particularly to a back rubbing machine that is easy to adjust. Background Technology

[0002] Vertical back grinders can be used to manufacture various industrial synchronous belts, including multi-wedge T-tooth synchronous belts, arc-shaped synchronous belts, S-tooth synchronous belts, parabolic synchronous belts, GY-tooth synchronous belts, etc. Due to their vertical structure, reasonable structure, and convenient operation, they have been widely used.

[0003] refer to Figure 1 Currently, existing back-grinding machines include a frame 1, a grinding assembly 2, a mounting assembly 4, and a clamping assembly 5. The grinding assembly 2 includes a grinding roller 21 and a grinding motor 22. The grinding roller 21 is horizontally positioned and rotatably connected to the frame 1. The grinding motor 22 is fixedly mounted on the frame 1 and drives the grinding roller 21 to rotate. The mounting assembly 4 includes a main roller 42 and a mounting frame 41. The mounting frame 41 is fixedly connected to the frame 1 by bolts. The main roller 42 is horizontally positioned and rotatably connected to the mounting frame 41. The clamping assembly 5 includes a sliding plate 51 and two... Mounting block 52, cylinder 55, pressing motor 56, and pressure roller 53 are installed. Sliding plate 51 is located on the side of main roller 42 away from grinding roller 21. Sliding plate 51 is slidably connected to frame 1 in the direction close to or away from main roller 42. Mounting block 52 is bolted to sliding plate 51. Two mounting blocks 52 are distributed along the length of grinding roller 21. Pressure roller 53 is rotatably connected to two mounting blocks 52. Cylinder 55 is fixedly installed on frame 1. Cylinder 55 is used to drive sliding plate 51 to slide. Pressing motor 56 is installed on mounting block 52 and drives pressure roller 53 to rotate.

[0004] When the grinding machine is working, the operator places the conveyor belt to be processed onto the main roller 42, extends the piston rod of the cylinder 55, and drives the mounting block 52 to move, so that the pressure roller 53 abuts against the conveyor belt 9 to be processed on the main roller 42. Since the diameter of the conveyor belt 9 to be processed is larger than the diameter of the main roller 42, under the abutment of the pressure roller 53, the conveyor belt 9 to be processed is connected to the grinding roller 21. During operation, the operator drives the grinding motor 22, which drives the grinding roller 21 to grind the conveyor belt 9 to be processed. At this time, the drive motor 34 starts, driving the pressure roller 53 to rotate. The rotation of the pressure roller 53 drives the conveyor belt to be processed to rotate one revolution, grinding the conveyor belt to be processed circumferentially.

[0005] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Due to the high precision requirements of conveyor belt grinding, during the initial installation of the back grinding machine, it is necessary to adjust the grinding roller, main roller, and pressure roller to be parallel to each other. Since the adjustment between the mounting frame and the machine frame, as well as between the mounting block and the sliding plate, is only made through the allowance of the bolt holes, the adjustment range is small and the adjustment is difficult. The main roller and pressure roller are both long, making it difficult to control the parallelism between the grinding roller, main roller, and pressure roller. This often results in the need for multiple position adjustments, and the weight of each component makes the installation and adjustment of the back grinding machine quite troublesome. Summary of the Invention

[0006] To facilitate the installation and adjustment of the back-grinding machine, this application provides a back-grinding machine that is easy to adjust.

[0007] This application provides an easily adjustable back-grinding machine, which adopts the following technical solution:

[0008] An easily adjustable back-grinding machine includes a frame, a grinding roller, a sliding assembly, a sleeve assembly, and a clamping assembly. The grinding roller is rotatably connected to the frame. The sliding assembly includes two screws, two sliding blocks, and two driving components. The two sliding blocks are distributed along the length of the grinding roller and are slidably connected to the frame in a direction close to or away from the grinding roller. Each of the two screws corresponds to one of the two sliding blocks, and the sliding blocks are threadedly connected to the screws. The two driving components are connected to the two sleeves... The screws are in one-to-one correspondence. The driving component is used to drive the screws to rotate. The two sliding blocks are the first sliding block and the second sliding block. The sleeve assembly includes a mounting frame and a main roller. The mounting frame is threaded to the first sliding block. One end of the main roller is rotatably connected to the mounting frame. The pressing assembly includes a sliding plate, two mounting blocks and a pressure roller. The sliding plate is slidably connected to the two sliding blocks. The two mounting blocks are threaded to the sliding plate. The pressure roller is rotatably connected to the two mounting blocks.

[0009] By adopting the above technical solution, when the back grinding machine needs to be positioned and installed, the operator drives the drive component, which drives the screw to rotate. The screw drives the sliding block to move. The sliding block makes it easier to adjust the angle between the pressure roller and the grinding roller, reducing the tedious operation time of loosening and fixing the pressure roller with bolts. Since the angle that the pressure roller needs to be adjusted is small but needs to be precise, the rotation of the screw can improve the adjustment accuracy of the pressure roller. The small change in the angle between the pressure roller and the mounting block will not affect the normal rotation of the pressure roller. After that, the operator only needs to adjust the angle between the main roller and the pressure roller to complete the adjustment of the main roller. The sliding component has a simple mechanism, a reliable screw structure, high adjustment accuracy, and a built-in locking effect. The sliding component improves the installation and adjustment time of the back grinding machine and facilitates the adjustment of the back grinding machine.

[0010] Optionally, the frame is further provided with a control component for controlling the moving distance of the sliding assembly. The control component includes a plurality of proximity switches, which are disposed on the mounting bracket, and the plurality of proximity switches have different sensing distances.

[0011] By adopting the above technical solution, during the grinding process of the conveyor belt in the back grinder, the diameter of the conveyor belt to be processed will be larger than the diameter of the main roller. Under the pressure of the pressure roller, the end of the conveyor belt to be processed away from the pressure roller and abuts against the grinding roller. The operator can control the distance between the sliding block and the grinding roller through a proximity switch. Changing the distance between the sliding block and the grinding roller is equivalent to changing the distance between the main roller and the grinding roller, but the distance between the main roller and the pressure roller is not convenient. This allows the back grinder to process conveyor belts of different diameters. By controlling the proximity switch, the distance can be adjusted to the same number of proximity switches, thus improving the applicability of the back grinder.

[0012] Optionally, the frame is also provided with an anti-tilting component for reducing the tilting of the main roller during operation. The anti-tilting component includes a ejector pin and an ejector cylinder. A circular groove is opened at one end of the main shaft away from the mounting frame. The ejector pin is slidably connected to the second sliding block. The ejector pin is used to pass into the circular groove. The ejector cylinder is used to drive the ejector pin to move.

[0013] By adopting the above technical solution, after the conveyor belt to be processed is fitted onto the main roller, and the pressure roller abuts against the conveyor belt, the operator will activate the ejector cylinder. The piston rod of the ejector cylinder drives the ejector pin to move. Driven by the piston rod, the ejector pin abuts against the circular groove of the main roller. The circular groove restricts the relative movement between the ejector pin and the main roller, reducing the imbalance of force at both ends of the main roller during the grinding of the conveyor belt and preventing the main roller from tilting. When the conveyor belt to be ground is finished, the piston rod of the cylinder retracts, and the ejector pin moves away from the main roller, making it easier for the operator to remove the finished conveyor belt from the main roller. The anti-tilting component and the mounting frame work together at both ends of the main roller to reduce the angle of tilt of the main roller after being pressed by the pressure roller, further reducing the angle between the conveyor belt to be ground and the grinding roller during the processing, and improving the processing quality of the conveyor belt to be ground.

[0014] Optionally, the frame is provided with a transport assembly for facilitating the placement of the conveyor belt to be processed onto the main roller. The transport assembly includes an inclined plate, a rotating disk, and a drive component for rotating the rotating disk. The rotating disk has several placement slots on its sidewall for placing the conveyor belt to be processed. The placement slots are through-holes. The rotating disk is rotatably connected to the second sliding block. The inclined plate is used to place the conveyor belt to be processed and guide it into the placement slots. The inclined plate is provided with a control unit for intermittently conveying several conveyor belts to be processed. The transport assembly also includes a conveying unit, which includes a synchronous belt and a drive motor. The synchronous belt is disposed on the second sliding block, and the length direction of the synchronous belt is parallel to the length direction of the main roller. The drive motor is used to drive the synchronous belt to rotate.

[0015] By adopting the above technical solution, the operator places several conveyor belts to be processed on the inclined plate. The control unit sequentially conveys the conveyor belts to be processed. The drive component drives the rotating disk to rotate. Under the inclined guidance of the inclined plate, the conveyor belts to be processed enter the placement slots of the transmission disk. Multiple placement slots can hold multiple conveyor belts to be processed. The rotating disk drives the conveyor belts to be processed to move. When the conveyor belts to be processed are aligned with the main roller, the conveyor belt of the conveyor unit just comes into contact with the conveyor belts to be processed. The synchronous belt uses friction to lift the conveyor belts out of the placement slots and onto the main roller, thus completing the feeding of the conveyor belts to be processed. The transport component can transport multiple conveyor belts to be processed, and the inclined plate can store multiple conveyor belts to be processed. The transport component reduces the efficiency of the operator in handling the conveyor belts to be processed, and the conveyor unit facilitates the entry of the conveyor belts to be processed onto the main roller.

[0016] Optionally, the rotating disk is provided with a limiting component to reduce the conveyor belt to be processed from leaving the placement slot. The limiting component includes a plurality of limiting tubes, which correspond one-to-one with a plurality of placement slots. The limiting tubes are rotatably connected to the placement slots. A through groove is provided on the inner side wall of the limiting tube, and the through groove passes through the limiting tube.

[0017] By adopting the above technical solution, the conveyor belt to be processed slides along the inclined plate into the highest placement groove under the action of gravity. Under the action of gravity, the through groove is always located above the limiting tube. The limiting tube does not interfere with the process of the conveyor belt to be processed entering the placement groove. The rotating disk rotates under the action of the driving component. The conveyor belt to be processed gradually moves downward in the placement groove. The limiting tube, which is not at the highest point, and the inner wall of the placement groove work together to form a circumferentially sealed annular limiting space. The conveyor belt to be processed cannot detach from the placement groove under the combined action of the limiting tube and the placement groove. As the rotating disk rotates, the conveyor belt to be processed contacts the synchronous belt and is sleeved on the main roller under the action of the synchronous belt.

[0018] Optionally, the control unit includes a rotating plate, a blocking plate, and a rotating component for driving the rotating plate to rotate. The rotating plate is rotatably connected to one end of the inclined plate near the rotating disk. The blocking plate is slidably connected to the inclined plate along an angle perpendicular to the inclined plate. The rotating plate is used to drive the blocking plate to slide.

[0019] By adopting the above technical solution, when the inclined plate is aligned with the placement slot of the rotating disk, the rotating component drives the rotating plate that was originally blocking the conveyor belt to be processed to rotate. At this time, the conveyor belt to be processed on the inclined plate enters the placement slot by its own weight. During the rotation, the rotating plate abuts against the blocking plate, and the blocking plate slides under the action of the rotating plate, blocking the subsequent conveyor belt to be processed, so that only one conveyor belt to be processed falls off each time it passes through a placement slot. When the rotating disk continues to rotate, the rotating component drives the rotating plate to rotate in the opposite direction. Under the action of gravity, the blocking plate moves away from the conveyor belt to be processed. At this time, the conveyor belt to be processed abuts against the rotating plate, and the rotating plate blocks the conveyor belt to be processed from entering the placement slot. The above steps are repeated until the next time the inclined plate is aligned with the rotating disk.

[0020] Optionally, the rotating component includes a drive gear, several locking teeth, and a torsion spring. The locking teeth are evenly distributed circumferentially along the axis of the rotating disk. The drive gear is disposed on the rotation axis of the rotating plate and meshes with the locking teeth. The torsion spring is used to keep the rotating plate from blocking the conveyor belt to be processed on the inclined plate.

[0021] By adopting the above technical solution, during the rotation of the rotating disk, the cleats on the rotating disk drive the drive gear to rotate, the drive gear drives the rotating plate to rotate, and the rotating plate drives the abutment plate to rotate during the rotation. The abutment plate abuts against the blocking plate, and the blocking plate slides down under the action of the abutment plate. The blocking plate blocks the subsequent conveyor belt to be processed, so that only one conveyor belt to be processed falls off at a time by the control unit. When the rotating disk continues to rotate, the drive gear moves relative to the rotating disk to the position of the placement slot. The drive gear disengages from the cleats, and the rotating plate is subjected to the action of the torsion spring, and the rotating plate rotates in the opposite direction. The abutment plate rotates with the rotating plate, and the blocking plate moves away from the conveyor belt to be processed under the action of gravity. At this time, the conveyor belt to be processed abuts against the rotating plate, and the rotating plate blocks the conveyor belt to be processed from entering the placement slot. The above steps are repeated until the tilting plate is aligned with the position of the rotating disk.

[0022] Optionally, the driving component includes a rotating gear, a contact plate, a contact block, and a driving motor. The rotating gear is disposed on the rotating plate, the contact plate is rotatably connected to the second sliding block, the contact block is disposed on the contact plate, the contact block is used to drive the rotating contact gear to rotate, and the driving motor is used to drive the contact plate to rotate.

[0023] By adopting the above technical solution, the motor drives the abutment plate to rotate. During one rotation of the rotating plate, the abutment block drives the actuating gear to rotate. The actuating gear rotates the angle between two adjacent placement slots on the mounting plate. The driving component makes the rotating plate rotate the same angle each time, which facilitates the conveyor belt to be processed on the inclined plate to enter the placement slot of the rotating plate. When the rotating plate is not rotating, it also makes it easier for the conveyor belt to be processed opposite to the main roller to enter the main roller under the transmission of the synchronous belt.

[0024] Optionally, the rotating disk has several through holes, which are spaced apart from the mating holes. The first sliding block is equipped with an ejection cylinder, which is used to eject the processed conveyor belt from the main roller.

[0025] By adopting the above technical solution, when the conveyor belt has been polished, the piston rod of the ejector cylinder extends, pushing the polished conveyor belt out of the main roller. The polished conveyor belt then enters the through hole of the rotating disk, making it easy for workers to remove the polished conveyor belt.

[0026] Optionally, the conveying unit further includes a rotating frame, which is rotatably connected to the second sliding block. The timing belt is disposed on the rotating frame, and the rotation axis of the rotating frame is parallel to the rotation axis of the rotating disk. The second sliding block is provided with a flipping component for rotating the rotating frame. The flipping component includes a first flipping gear and a second flipping gear. The first flipping gear is disposed on the rotating disk, and the second flipping gear is disposed on the rotating frame. The first flipping gear meshes with the second flipping gear.

[0027] By adopting the above technical solution, the first flipping gear rotates with the rotating disk, the second flipping gear drives the second flipping gear to rotate, and the rotating frame is rotatably connected to the second sliding block. When the conveyor belt to be processed on the rotating disk abuts against the synchronous belt, the synchronous belt abuts against the conveyor belt to be processed and uses friction to send the conveyor belt to be processed into the main roller. After that, as the rotating disk rotates, the rotating frame rotates with the rotating disk and completes the flipping. At this time, the through hole is directly opposite the main roller. Because the rotating frame flips, the synchronous belt abuts against the conveyor belt that has been polished, which makes it easier for the conveyor belt that has been polished to detach from the main roller.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The sliding assembly allows workers to easily adjust the grinding roller, pressure roller, and main roller to be parallel to each other;

[0030] 2. The anti-tilting component reduces the offset angle of the main roller after it is squeezed by the pressure roller;

[0031] 3. The transport assembly is used to sequentially feed several conveyor belts to be processed onto the main roller, and to send the polished conveyor belts out of the main roller. Attached Figure Description

[0051] refer to Figure 1 and Figure 2 The clamping assembly 5 includes a sliding plate 51, two mounting blocks 52, a pressure roller 53, a connecting plate 54, a cylinder 55, and a clamping motor 56. The sliding plate 51 is horizontally positioned on the side of the main roller 42 away from the grinding roller 21. The sliding plate 51 is bolted to the first sliding block 321 and the second sliding block 322. The two mounting blocks 52 are fixedly mounted on the upper surface of the sliding plate 51 and are distributed along the length of the main roller 42. The connecting plate 54 is vertically positioned. The connecting plate 54 is connected to two mounting blocks 52 at both ends. The cylinder 55 is fixedly mounted on the sliding plate 51, and the piston rod of the cylinder 55 is fixedly mounted on the connecting plate 54. The length of the pressure roller 53 is parallel to the length of the main roller 42. The pressure roller 53 is displaced between the two mounting blocks 52. The pressure roller 53 is rotatably connected to the mounting blocks 52. The pressing motor 56 is fixedly mounted on the mounting blocks 52, and the output shaft of the pressing motor 56 is fixedly mounted on the rotation axis of the pressure roller 53.

[0052] The implementation principle of an easily adjustable back-grinding machine according to an embodiment of this application is as follows: The back-grinding machine requires initial installation and adjustment. The operator first installs the clamping assembly 5 on the frame 1, then connects the sliding plate 51 to two sliding blocks 32 via threads, and then installs the sliding blocks 32 on the sliding plate 51. Next, the cylinder 55 and the pressure roller 53 are installed on the sliding blocks 32. During the adjustment process, the operator starts two screws 31, which move the two sliding blocks 32 to a suitable position. Then, the operator can start one side of the screw 31 to fine-tune the parallelism between the pressure roller 53 and the grinding roller 21. After adjusting the pressure roller 53, the operator connects the mounting frame 41 to the first sliding block 321 via threads, and then installs the main roller 42 on the mounting frame 41. The operator can then adjust the bolts on the mounting frame 41 to ensure the main roller 42 remains parallel to the pressure roller 53, thus completing the initial installation of the back-grinding machine.

[0053] When the back-grinding machine is working, the operator controls the distance between the main roller 42 and the grinding roller 21 by using proximity switches 81 with different detection distances, based on the diameter of the grinding conveyor belt. Then, the operator places the conveyor belt 9 to be processed onto the inclined plate 71 and starts the drive motor 734. The drive motor 734 drives the abutment plate 732 to rotate. The abutment block 733 on the abutment plate 732 drives the rotating gear 731 to rotate intermittently. The rotating gear 731, in turn, drives the rotating disk 72 to rotate. During the rotation of the rotating disk 72, the locking teeth 746 on the rotating disk 72 mesh with the drive gear 745, driving the rotating plate 74... As the rotating plate 741 rotates, its abutting plate 742 abuts against the blocking plate 743 as it gradually becomes parallel to the inclined plate 71. The blocking plate 743 blocks the remaining conveyor belt 9 to be processed on the inclined plate 71. The conveyor belt 9 to be processed that is not blocked by the blocking plate 743 falls down along the inclined plate 71 and the rotating plate 741 into the placement slot 721 of the rotating disk 72. As the rotating disk 72 rotates, the drive gear 745 disengages from the locking tooth 746. At this time, the torsion spring 747 on the rotating plate 741 rotates the rotating plate 741 in the opposite direction. The blocking plate 743 returns to its original position under the action of gravity, and the remaining conveyor belt 9 to be processed is abutted by the rotating plate 741.

[0054] The conveyor belt to be processed, located on the transmission disc, gradually moves downwards during the conveying process. At this time, the limiting tube 725 on the rotating disc 72 always keeps the through groove 726 facing upwards under the action of gravity, so that the conveyor belt to be processed is always confined within the placement groove 721. When the conveyor belt to be processed 9 moves to the lowest point, the synchronous belt 751 abuts against the conveyor belt to be processed 9. Through friction, the synchronous belt 751 sends the conveyor belt to be processed 9 onto the main roller 42, completing the feeding of the conveyor belt to be processed.

[0055] After the conveyor belt on the main roller 42 has finished grinding, the operator drives the ejection cylinder 43 to push the conveyor belt sleeved on the main roller 42 out of the main roller 42. At this time, the rotating disk 72 is still rotating. The rotation of the rotating disk 72 drives the first flip gear 756 to rotate. The first flip gear 756 drives the second flip gear 757 to rotate. The second flip gear 757 drives the rotating frame 753 to rotate 180 degrees. At this time, the transmission direction of the synchronous belt 751 on the rotating frame 753 changes. The processed conveyor belt passes through the through hole 723 of the rotating disk 72 under the action of the synchronous belt 751, and the operator can then collect the completed conveyor belt.

[0056] 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.
