Description

Technical Field

[0001] The present application relates to the technical field of motor housing polishing, and in particular to a housing polishing device for motor production. Background Art

[0002] As an important device that converts electrical energy into mechanical energy, motors cover most industrial and civil fields. In mechanical manufacturing, such as machine tools, presses, rolling mills, etc., motors are the core components of driving equipment. In mining, motors are used to drive equipment such as hoists, conveyor belts and fans inside mines to operate.

[0003] Since there may be burrs, scratches or unevenness on the surface of the shell after casting or processing, the surface of the shell needs to be polished to make the appearance of the shell neat. In addition, since some shells need to be painted, anodized, etc., polishing the shell surface can enhance the adhesion strength of the coating and avoid shedding or unevenness due to rough surface.

[0004] Due to the different types of motors, the shapes of the motor shells are inconsistent. When grinding a round motor shell, the motor shell can be grinded by driving the motor shell to rotate. When grinding a square motor shell, the motor shell needs to be clamped and a transmission roller is used to drive the sanding belt to grind the side wall of the square motor shell.

[0005] Referring to the Chinese patent application document with publication number CN117300840A, the subject name is a housing polishing device for motor production. The device is provided with a polishing mechanism that can be rotated and adjusted. When the motor housing needs to be polished, the motor housing is placed on the polishing mechanism, and after one end is polished, the polishing mechanism is driven to rotate, so that all parts of the motor housing can be polished.

[0006] In view of the above technical solution, a sanding block or sanding belt is usually used to grind the motor housing. The use of the sanding belt can apply uniform pressure to the motor housing, making the grinding process more uniform to reduce the uneven grinding of the motor housing surface. When grinding the side wall of the square housing, since it is necessary to grind the installation groove on the side wall of the square housing, the square housing needs to be rotated. After the rotation, the position of the sanding belt or sanding block needs to be adjusted to move the sanding belt or sanding block to the installation groove to grind the installation groove of the square housing. When grinding the installation groove, the position of the square housing and the sanding belt or sanding block needs to be adjusted, which affects the grinding efficiency. Summary of the invention

[0007] In view of this, the present application provides a housing grinding device for motor production, which is intended to solve the problem of needing to stop the machine for adjustment when grinding the mounting groove of a square motor.

[0008] A housing polishing device for motor production provided in the present application adopts the following technical scheme, including a mounting frame and a clamping mechanism arranged on the mounting frame for clamping the motor housing; a connecting plate is fixedly connected to the mounting frame, an abutment cylinder is fixedly connected to the connecting plate, an end of the output shaft of the abutment cylinder away from the abutment cylinder is fixedly connected to the abutment plate, a connecting shaft is rotatably connected to the abutment plate, a cross connecting frame is rotatably connected to the connecting shaft, an abutment roller is rotatably connected to the cross connecting frame, and the abutment roller is rotatably connected to the cross connecting frame at the end position of the cross connecting frame, a grinding belt is rotatably connected to the connecting plate, and the abutment roller abuts against the inner side of the grinding belt.

[0009] The square motor housing is placed on the clamping mechanism, and the clamping mechanism clamps the square motor housing. The cross connecting frame is rotated to make the two end points of the cross connecting frame contact the grinding belt, and the middle position of the two end points abuts against the side wall of the square motor housing to grind the side wall of the square motor housing. After grinding the square motor housing, the cross connecting frame is driven to rotate, so that one end point of the cross connecting frame contacts the grinding belt, and the clamping mechanism is rotated to drive the square motor housing to rotate, so that one end point of the cross connecting frame moves to the installation groove of the square motor housing, and the installation groove is grinded. By grinding the installation groove of the square motor housing, the surface treatment quality of the motor housing can be made consistent, and the time for replacing the grinding tool can be reduced, thereby improving the grinding efficiency.

[0013] By driving the sanding belt to be tensioned, the sanding belt can maintain appropriate tension during the sanding process, thereby maintaining the sanding effect of the sanding belt and improving the sanding quality. In addition, appropriate tension can prevent the sanding belt from sliding or falling off during operation, reduce the wear of the sanding belt, and extend its service life.

[0014] Optionally, an abutment rod is fixedly connected to the abutment plate, an abutment spring is fixedly connected to the abutment rod, a receiving plate is fixedly connected to the abutment cylinder, and the receiving plate and the abutment spring are fixedly connected.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the embodiments of the present application. Figure 1-Figure 8 , the technical solutions of the embodiments of the present application are clearly and completely described. Based on the described embodiments of the present application, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of this application.

[0028] like Figure 1 As shown, this embodiment provides a motor housing grinding device for production, including a mounting frame 1, a clamping mechanism 2, a grinding mechanism, an abutting mechanism, an adjusting mechanism, a tensioning mechanism, a moving mechanism and a driven mechanism. The clamping mechanism 2 is arranged at the middle position of the mounting frame 1, and the clamping mechanism 2 is used to abut against the internal position of the motor housing so that the motor housing is located in the middle of the mounting frame 1. The abutting mechanism is used to abut against the side wall of the motor housing. The grinding mechanism is used to grind the motor housing. The abutting mechanism is used to make the sanding belt 36 in the grinding mechanism close to the side wall of the motor housing. The adjusting mechanism is used to drive the abutting mechanism to perform fine adjustment when grinding the mounting groove of the motor housing. The tensioning mechanism is used to control the tensioning degree of the sanding belt 36. The moving mechanism is used to drive the motor housing to move in the horizontal direction. The driven mechanism is used to make the abutting mechanism rotate synchronously with the rotation direction of the motor housing when adjusting the motor housing.

[0029] like Figure 5 , Figure 6 and Figure 7As shown, the clamping mechanism 2 includes a sliding plate 21, a clamping cylinder 22, a bevel block 23, a clamping plate 24, a clamping block 241 and an abutment block 25. The sliding plate 21 is slidably connected to the mounting frame 1, the clamping cylinder 22 is rotatably connected to the sliding plate 21, the output shaft of the clamping cylinder 22 penetrates the sliding plate 21, the bevel block 23 is fixedly connected to the output shaft of the clamping cylinder 22, and a plurality of bevel blocks 23 are provided, and the plurality of bevel blocks 23 are axially arrayed and distributed on the output shaft of the clamping cylinder 22 The clamping plate 24 is rotatably connected to the sliding plate 21, and the clamping plate 24 is set to a truncated cone shape. The clamping block 241 is slidably connected to the clamping plate 24, and there are multiple clamping blocks 241. The number of clamping blocks 241 corresponds to the number of bevel blocks 23. The clamping blocks 241 are axially arrayed on the clamping plate 24. There are multiple abutment blocks 25, and a single abutment block 25 is fixedly connected to the clamping block 241 and is set toward the side of the output shaft close to the clamping cylinder 22.

[0030] When the motor housing needs to be clamped, the motor housing is placed on the side of the sliding plate 21 away from the clamping cylinder 22, and the clamping cylinder 22 is started to move the output shaft of the clamping cylinder 22 toward the side close to the motor housing. After moving to a certain extent, the bevel block 23 on the output shaft of the clamping cylinder 22 abuts against the abutment block 25, and at this time, the bevel block 23 pushes the abutment block 25 and the clamping block 241 toward the inner wall of the motor housing, so that the inner wall of the motor housing abuts against the clamping block 241. Due to the axial array distribution of the clamping blocks 241, the centering of the motor housing is completed when all the clamping blocks 241 abut against the inner wall of the motor housing.

[0031] like Figure 5 and Figure 6 As shown, the moving mechanism includes a moving motor 26, a moving screw rod 27, a rotating motor 28, a rotating gear 29 and a driven gear 291. The moving motor 26 is fixedly connected to the mounting frame 1 and is arranged in the middle position of the mounting frame 1. The moving screw rod 27 is fixedly connected to the output shaft of the moving motor 26. The moving screw rod 27 and the sliding plate 21 are connected by a threaded connection. The rotating motor 28 is fixedly connected to the sliding plate 21. The rotating gear 29 is fixedly connected to the output shaft of the rotating motor 28. The driven gear 291 and the clamping cylinder 22 are fixedly connected, and the driven gear 291 and the clamping plate 24 are fixedly connected.

[0032] When it is necessary to drive the motor housing to move, start the moving motor 26 to rotate the output shaft of the moving motor 26, and the rotation of the output shaft of the moving motor 26 drives the moving screw 27 to rotate. Due to the threaded connection between the moving screw 27 and the sliding plate 21, the moving screw 27 can drive the sliding plate 21 to move horizontally during the rotation. When it is necessary to adjust the angle of the motor housing, start the rotating motor 28 to rotate the output shaft of the rotating motor 28, and the rotation of the output shaft of the rotating motor 28 drives the rotating gear 29 to rotate. The rotation of the rotating gear 29 drives the driven gear 291 to rotate, so that the driven gear 291 drives the clamping cylinder 22 and the clamping plate 24 to rotate, thereby realizing the adjustment of the angle of the motor housing.

[0033] like Figure 2 and Figure 3 As shown, the grinding mechanism includes a connecting plate 3, a grinding belt 36, a transmission roller 7 and a transmission motor 71. The connecting plate 3 is fixedly connected to the mounting frame 1, the grinding belt 36 is sleeved on the connecting plate 3, the transmission roller 7 is rotatably connected to the connecting plate 3, the transmission motor 71 is fixedly connected to the connecting plate 3, and the output shaft of the transmission motor 71 and the transmission roller 7 are connected by belt transmission. When the grinding belt 36 needs to be driven to rotate, the transmission motor 71 is started, the transmission motor 71 drives the transmission roller 7 to rotate, and the transmission roller 7 drives the grinding belt 36 to rotate.

[0034] like Figure 2 As shown, the abutment mechanism includes an abutment cylinder 31, an abutment plate 32, a connecting shaft 33, a cross connecting frame 34 and an abutment roller 35. The abutment cylinder 31 is fixedly connected to the connecting plate 3, the abutment plate 32 is fixedly connected to the output shaft of the abutment cylinder 31, and is arranged on the side of the output shaft of the abutment cylinder 31 away from the abutment cylinder 31, the connecting shaft 33 is rotatably connected to the abutment plate 32, the cross connecting frame 34 is rotatably connected to the connecting shaft 33, and the abutment roller 35 is rotatably connected to the cross connecting frame 34, and is arranged at the end point position of the cross connecting frame 34.

[0035] When the side wall of the circular motor is being polished, the sanding belt 36 is driven to rotate by the transmission motor 71, and the abutment cylinder 31 is started, so that the abutment cylinder 31 drives the cross-connecting frame 34 to move toward the side close to the sanding belt 36, and the cross-connecting frame 34 is rotated so that two end points of the cross-connecting frame 34 abut against the inner wall of the sanding belt 36, so that the sanding belt 36 and the side wall of the circular motor housing at the middle position of the two end points of the cross-connecting frame 34 abut against each other, and the side wall of the circular motor housing is polished under the drive of the transmission motor 71. When the side wall of the square motor is being polished, the above operation is repeated.

[0036] When grinding the installation groove of the square motor, start the rotating motor 28 so that the output shaft of the rotating motor 28 drives the rotating gear 29 to rotate, and the rotating gear 29 rotates to drive the driven gear 291 to rotate, and the driven gear 291 rotates to drive the clamping cylinder 22 to rotate, so that the cross connecting frame 34 changes from the two end points abutting against the frosting belt 36 to a single end point contacting the frosting belt 36, and after the contact, start the transmission motor 71, so that the transmission motor 71 drives the frosting belt 36 to rotate, and the installation groove of the square motor is grinded by the frosting belt 36.

[0037] like Figure 4 As shown, the adjustment mechanism includes a first adjustment block 4, an adjustment ring 41, a second adjustment block 42, an adjustment spring 43 and an adjustment motor 9. The first adjustment block 4 is fixedly connected to the cross connecting frame 34, the adjustment ring 41 is detachably connected to the first adjustment block 4, the second adjustment block 42 is fixedly connected to the connecting shaft 33, and the second adjustment block 42 and the adjustment ring 41 are detachably connected, the adjustment spring 43 is sleeved on the adjustment ring 41, and the two ends of the adjustment spring 43 are respectively fixedly connected to the first adjustment block 4 and the second adjustment block 42, the adjustment motor 9 is fixedly connected to the connecting plate 3, and the output shaft of the adjustment motor 9 and the connecting shaft 33 are connected by gear transmission.

[0038] When it is necessary to drive the cross connecting frame 34 to rotate, the adjustment motor 9 is started to rotate the output shaft of the adjustment motor 9, and the connecting shaft 33 is driven to rotate by gear transmission. Since the connecting shaft 33 and the cross connecting frame 34 are rotatably connected, the connecting shaft 33 fails to drive the cross connecting frame 34 to rotate when it first rotates. At this time, the adjustment spring 43 at the middle position of the first adjustment block 4 and the second adjustment block 42 is in a compressed state. After rotating to a certain extent, the cross connecting frame 34 is located in the middle position of the installation groove. The adjustment motor 9 is turned off, so that the two side walls of the installation groove push the cross connecting frame 34, so that the cross connecting frame 34 is located in the middle position of the installation groove.

[0039] like Figure 4 As shown, the tensioning mechanism includes a tensioning block 5, a tensioning rod 51, a tensioning spring 52 and a tensioning roller 53. The tensioning block 5 is fixedly connected to the connecting plate 3, the tensioning rod 51 is slidably connected to the tensioning block 5, the tensioning spring 52 is fixedly connected to the tensioning block 5, and one end of the tensioning spring 52 is fixedly connected to the tensioning block 5. The tensioning roller 53 is rotatably connected to the tensioning rod 51 and is arranged at one end of the tensioning rod 51 away from the tensioning block 5. The tensioning roller 53 abuts against the inner wall of the abrasive belt 36.

[0040] When the cross-connecting frame 34 is changed from the abutting rollers 35 on the two end points abutting against the side walls of the frosted belt 36 to the abutting rollers 35 on the single end point abutting against the side walls of the frosted belt 36, the frosted belt 36 lacks a part of support, and is in a relaxed state. Since the frosted belt 36 is in a relaxed state, the tensioning roller 53 lacks the pulling of the frosted belt 36, and is pushed by the tensioning spring 52 to move toward the side close to the frosted belt 36, so that the tensioning roller 53 pushes the frosted belt 36 to be tightened.

[0041] like Figure 3 and Figure 8 As shown, the driven mechanism includes an abutment rod 6, an abutment spring 61, a receiving plate 62, a sliding groove 8 and a sliding block 81. The abutment rod 6 is fixedly connected to the abutment plate 32, the abutment spring 61 is fixedly connected to the abutment rod 6, the receiving plate 62 is fixedly connected to the abutment cylinder 31, and is arranged on the side of the abutment cylinder 31 close to the output shaft, the abutment rod 6 and the receiving plate 62 are slidingly connected, the side of the abutment spring 61 away from the abutment rod 6 is fixedly connected to the receiving plate 62, the sliding groove 8 is opened on the connecting plate 3, and the sliding block 81 is fixedly connected to the abutment plate 32 and is slidingly connected in the sliding groove 8.

[0042] When the cross-connecting frame 34 is changed from the abutment rollers 35 on the two end points abutting against the side walls of the frosting belt 36 to the abutment rollers 35 on the single end point abutting against the side walls of the frosting belt 36, due to the length limitation of the cross-connecting frame 34, the abutment plate 32 moves toward the side away from the side wall of the square motor so that the abutment rod 6 pushes the abutment spring 61 to be compressed, and the sliding block 81 located on the abutment plate 32 slides in the sliding groove 8.

[0043] When the present application is in use, the motor housing is placed on the side of the sliding plate 21 away from the clamping cylinder 22, and the clamping cylinder 22 is started to move the output shaft of the clamping cylinder 22 toward the side close to the motor housing. After moving to a certain extent, the bevel block 23 on the output shaft of the clamping cylinder 22 abuts against the abutment block 25, and at this time, the bevel block 23 pushes the abutment block 25 and the clamping block 241 toward the inner wall of the motor housing, so that the inner wall of the motor housing abuts against the clamping block 241. Due to the axial array distribution of the clamping blocks 241, the centering of the motor housing is completed when all the clamping blocks 241 abut against the inner wall of the motor housing.

[0044] Start the moving motor 26 to rotate the output shaft of the moving motor 26. The rotation of the output shaft of the moving motor 26 drives the moving screw 27 to rotate. Due to the threaded connection between the moving screw 27 and the sliding plate 21, the moving screw 27 can drive the sliding plate 21 to move horizontally during the rotation. When the angle of the motor housing needs to be adjusted, start the rotating motor 28 to rotate the output shaft of the rotating motor 28. The rotation of the output shaft of the rotating motor 28 drives the rotating gear 29 to rotate. The rotation of the rotating gear 29 drives the driven gear 291 to rotate, so that the driven gear 291 drives the clamping cylinder 22 and the clamping plate 24 to rotate, thereby realizing the adjustment of the angle of the motor housing.

[0045] When the side wall of the circular motor is being polished, the sanding belt 36 is driven to rotate by the transmission motor 71, and the abutment cylinder 31 is started, so that the abutment cylinder 31 drives the cross-connecting frame 34 to move toward the side close to the sanding belt 36, and the cross-connecting frame 34 is rotated so that two end points of the cross-connecting frame 34 abut against the inner wall of the sanding belt 36, so that the sanding belt 36 and the side wall of the circular motor housing at the middle position of the two end points of the cross-connecting frame 34 abut against each other, and the side wall of the circular motor housing is polished under the drive of the transmission motor 71. When the side wall of the square motor is being polished, the above operation is repeated.

[0046] When grinding the installation groove of the square motor, start the rotating motor 28 so that the output shaft of the rotating motor 28 drives the rotating gear 29 to rotate, and the rotating gear 29 rotates to drive the driven gear 291 to rotate, and the driven gear 291 rotates to drive the clamping cylinder 22 to rotate, so that the cross connecting frame 34 changes from the two end points abutting against the frosting belt 36 to a single end point contacting the frosting belt 36, and after the contact, start the transmission motor 71, so that the transmission motor 71 drives the frosting belt 36 to rotate, and the installation groove of the square motor is grinded by the frosting belt 36.

[0047] When it is necessary to drive the cross connecting frame 34 to rotate, the adjustment motor 9 is started to rotate the output shaft of the adjustment motor 9, and the connecting shaft 33 is driven to rotate by gear transmission. Since the connecting shaft 33 and the cross connecting frame 34 are rotatably connected, the connecting shaft 33 fails to drive the cross connecting frame 34 to rotate when it first rotates. At this time, the adjustment spring 43 at the middle position of the first adjustment block 4 and the second adjustment block 42 is in a compressed state. After rotating to a certain extent, the cross connecting frame 34 is located in the middle position of the installation groove. The adjustment motor 9 is turned off, so that the two side walls of the installation groove push the cross connecting frame 34, so that the cross connecting frame 34 is located in the middle position of the installation groove.

[0048] When the cross-connecting frame 34 is changed from the abutment rollers 35 on the two end points abutting against the side walls of the frosting belt 36 to the abutment rollers 35 on the single end point abutting against the side walls of the frosting belt 36, due to the length limitation of the cross-connecting frame 34, the abutment plate 32 moves toward the side away from the side wall of the square motor so that the abutment rod 6 pushes the abutment spring 61 to be compressed, and the sliding block 81 located on the abutment plate 32 slides in the sliding groove 8.

[0049] When the cross-connecting frame 34 is changed from the abutting rollers 35 on the two end points abutting against the side walls of the frosted belt 36 to the abutting rollers 35 on the single end point abutting against the side walls of the frosted belt 36, the frosted belt 36 lacks a part of support, and is in a relaxed state. Since the frosted belt 36 is in a relaxed state, the tensioning roller 53 lacks the pulling of the frosted belt 36, and is pushed by the tensioning spring 52 to move toward the side close to the frosted belt 36, so that the tensioning roller 53 pushes the frosted belt 36 to be tightened.

[0050] In this embodiment, when polishing the square motor casing, the square motor casing is polished by using a cross connecting frame 34, and after polishing the side wall of the square motor casing, the cross connecting frame 34 is driven to rotate so that one end point of the cross connecting frame 34 is moved to the mounting groove of the square motor casing, and the mounting groove of the square motor casing is polished. By polishing the mounting groove of the square motor casing, the surface treatment quality of the motor casing can be made consistent, and the time for replacing the polishing tool can be reduced, thereby improving the polishing efficiency.

[0051] In this embodiment, by centering and clamping the motor housing, the position of the motor housing during the grinding process can be accurately maintained, positioning errors can be reduced, and consistency of the grinding dimensions can be ensured. The clamped motor housing will not move during the grinding process, thereby improving stability during the grinding process and reducing grinding marks caused by vibration.

[0052] In this embodiment, by driving the sanding belt 36 to be tensioned, the sanding belt 36 can be better fitted to the surface of the workpiece, thereby improving the sanding efficiency, reducing the sanding time, and maintaining the sanding belt 36 in good working condition, thereby reducing the frequency of replacing the sanding belt 36, and reducing downtime and replacement costs.

[0053] The implementation principle of a motor housing grinding device in the embodiment of the present application is as follows: the motor housing is placed on the side of the sliding plate 21 away from the clamping cylinder 22, and the clamping cylinder 22 is started to move the output shaft of the clamping cylinder 22 toward the side close to the motor housing. After moving to a certain extent, the bevel block 23 on the output shaft of the clamping cylinder 22 abuts against the abutment block 25, and at this time, the bevel block 23 pushes the abutment block 25 and the clamping block 241 to move toward the inner wall of the motor housing, so that the inner wall of the motor housing abuts against the clamping block 241. Due to the axial array distribution of the clamping blocks 241, the centering of the motor housing is completed when all the clamping blocks 241 abut against the inner wall of the motor housing.

[0054] Start the moving motor 26 to rotate the output shaft of the moving motor 26. The rotation of the output shaft of the moving motor 26 drives the moving screw 27 to rotate. Due to the threaded connection between the moving screw 27 and the sliding plate 21, the moving screw 27 can drive the sliding plate 21 to move horizontally during the rotation. When the angle of the motor housing needs to be adjusted, start the rotating motor 28 to rotate the output shaft of the rotating motor 28. The rotation of the output shaft of the rotating motor 28 drives the rotating gear 29 to rotate. The rotation of the rotating gear 29 drives the driven gear 291 to rotate, so that the driven gear 291 drives the clamping cylinder 22 and the clamping plate 24 to rotate, thereby realizing the adjustment of the angle of the motor housing.

[0055] When the side wall of the circular motor is being polished, the sanding belt 36 is driven to rotate by the transmission motor 71, and the abutment cylinder 31 is started, so that the abutment cylinder 31 drives the cross-connecting frame 34 to move toward the side close to the sanding belt 36, and the cross-connecting frame 34 is rotated so that two end points of the cross-connecting frame 34 abut against the inner wall of the sanding belt 36, so that the sanding belt 36 and the side wall of the circular motor housing at the middle position of the two end points of the cross-connecting frame 34 abut against each other, and the side wall of the circular motor housing is polished under the drive of the transmission motor 71. When the side wall of the square motor is being polished, the above operation is repeated.

[0056] When grinding the installation groove of the square motor, start the rotating motor 28 so that the output shaft of the rotating motor 28 drives the rotating gear 29 to rotate, and the rotating gear 29 rotates to drive the driven gear 291 to rotate, and the driven gear 291 rotates to drive the clamping cylinder 22 to rotate, so that the cross connecting frame 34 changes from the two end points abutting against the frosting belt 36 to a single end point contacting the frosting belt 36, and after the contact, start the transmission motor 71, so that the transmission motor 71 drives the frosting belt 36 to rotate, and the installation groove of the square motor is grinded by the frosting belt 36.

[0057] When it is necessary to drive the cross connecting frame 34 to rotate, the adjustment motor 9 is started to rotate the output shaft of the adjustment motor 9, and the connecting shaft 33 is driven to rotate by gear transmission. Since the connecting shaft 33 and the cross connecting frame 34 are rotatably connected, the connecting shaft 33 fails to drive the cross connecting frame 34 to rotate when it first rotates. At this time, the adjustment spring 43 at the middle position of the first adjustment block 4 and the second adjustment block 42 is in a compressed state. After rotating to a certain extent, the cross connecting frame 34 is located in the middle position of the installation groove. The adjustment motor 9 is turned off, so that the two side walls of the installation groove push the cross connecting frame 34, so that the cross connecting frame 34 is located in the middle position of the installation groove.

[0058] When the cross-connecting frame 34 is changed from the abutment rollers 35 on the two end points abutting against the side walls of the frosting belt 36 to the abutment rollers 35 on the single end point abutting against the side walls of the frosting belt 36, due to the length limitation of the cross-connecting frame 34, the abutment plate 32 moves toward the side away from the side wall of the square motor so that the abutment rod 6 pushes the abutment spring 61 to be compressed, and the sliding block 81 located on the abutment plate 32 slides in the sliding groove 8.

[0059] When the cross-connecting frame 34 is changed from the abutting rollers 35 on the two end points abutting against the side walls of the frosted belt 36 to the abutting rollers 35 on the single end point abutting against the side walls of the frosted belt 36, the frosted belt 36 lacks a part of support, and is in a relaxed state. Since the frosted belt 36 is in a relaxed state, the tensioning roller 53 lacks the pulling of the frosted belt 36, and is pushed by the tensioning spring 52 to move toward the side close to the frosted belt 36, so that the tensioning roller 53 pushes the frosted belt 36 to be tightened.

[0060] The above is a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
