[0024] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please see the attached Figure 1 -Attached Figure 4The embodiment of the present invention provides an integrated production device for PVC doors of nursery pig houses, including a processing table 1, wherein the processing table 1 is internally rotatably connected to a plurality of lower conveying rollers 2, and a grinding assembly 3 is installed inside the processing table 1, and the grinding assembly 3 includes two upper and lower groups of grinding rollers 31 and two groups of grinding discs 33, the two ends of the two groups of grinding rollers 31 are respectively rotatably connected to the processing table 1, and the same ends of the two groups of grinding rollers 31 are respectively fixedly connected to a transmission gear 1 32, and the two transmission gears 1 32 are meshed and connected, and the outer wall of the processing table 1 is fixedly connected to a support seat 11, and the upper surface of the support seat 11 is fixedly connected to a motor 1 4, and the driving end of the motor 1 4 is transmission-connected to one end of the grinding roller 31 located at the lower side through a one-way clutch 10, and the side wall of the grinding disc 33 is fixedly connected to a connecting rod 34, and an electric push cylinder 35 is provided on the upper side of the connecting rod 34, and the electric push cylinder 35 passes through and is fixedly connected to the processing table 1, and the driving end of the electric push cylinder 35 is fixedly connected to a push plate 36, and the connecting rod 34 passes through and is rotatably connected to the push plate 36, and The connecting rod 34 passes through the processing table 1, and the connecting rod 34 is connected to the motor 4 through the driving mechanism 37. The top of the processing table 1 is fixedly connected to a mounting frame 5, and a rotating assembly 6 is installed at the center of the mounting frame 5. The rotating assembly 6 is used to drive the PVC plate 7 to rotate. The diameter and height of the lower conveying roller 2 and the grinding roller 31 are the same. The minimum spacing between the two grinding rollers 31 is the same as the thickness of the PVC plate 7. The active end of the one-way clutch 10 is fixedly connected to the driving end of the motor 4, and the driven end of the one-way clutch 10 is fixedly connected to the shaft end of the grinding roller 31. When the PVC plate 7 passes through the grinding disk 33, the motor 4 rotates forward and drives the driven end to rotate synchronously through the active end of the one-way clutch 10, thereby driving the grinding roller 31 to rotate. When the PVC plate 7 is conveyed in the reverse direction through the grinding disk 33, the motor 4 reverses, the locking element of the one-way clutch 10 is disengaged, the active end idles, and the driven end remains stationary. At this time, the grinding roller 31 stops rotating, thereby avoiding secondary over-grinding of the upper and lower surfaces of the PVC plate 7.

[0026] Specifically, the push plate 36 is used to connect the driving end of the electric push cylinder 35 and the connecting rod 34, so that the grinding disc 33 is driven to move horizontally by the extension and contraction of the electric push cylinder 35. When the PVC door needs to be processed, the PVC board 7 is placed on the lower conveying roller 2 and conveyed by the lower conveying roller 2 through the grinding roller 31. The motor 14 is operated and the lower grinding roller 31 is driven to rotate through the one-way clutch 10. The lower grinding roller 31 drives the connected transmission gear 132 to rotate. The transmission gear 132 drives another transmission gear 132 to rotate in the opposite direction. The other transmission gear 132 drives the upper grinding roller 31 to rotate, so that the motor 14 drives the two groups of grinding rollers 31 to rotate synchronously. The upper and lower surfaces of the PVC board 7 are polished respectively by the two groups of grinding rollers 31, and the grinding disc 33 is pushed to move relatively by the operation of the electric push cylinder 35, so that The spacing between the two grinding discs 33 is the same as the width of the PVC board 7. When the motor 4 is running, the connecting rod 34 is driven to rotate by the driving mechanism 37, so that the grinding disc 33 rotates, and then the left and right sides of the PVC board 7 are polished. After the PVC board 7 moves to the bottom of the rotating component 6, the electric push cylinder 35 is contracted to make the spacing between the two grinding discs 33 the same as the length of the PVC board 7. After the PVC board 7 is driven by the rotating component 6 to rotate 90°, the PVC board 7 is reversely conveyed through the grinding disc 33. At this time, the left and right sides of the rotated PVC board 7 can be polished, thereby realizing all-round polishing of the PVC board 7, quickly removing burrs and flash on the edges and surfaces of the PVC board 7, and improving the production and processing efficiency of the PVC board 7. Finally, after the polishing is completed, it is transported away by the lower conveying roller 2.

[0027] Please see the attached Figure 5 -Attached Figure 6 The driving mechanism 37 includes a driving gear 371 and two groups of driven gears 372. The two groups of driven gears 372 are respectively located on both sides of the processing table 1. The driving gear 371 is meshed with the adjacent driven gear 372. The driving gear 371 is fixedly mounted on the outer wall of the driving end of the motor 4. A notch is provided on the surface of the connecting rod 34. The connecting rod 34 passes through the driven gear 372. Corresponding protrusions are provided on the surface of the driven gear 372 corresponding to the notch. The side wall of the driven gear 372 is rotatably connected to the outer wall of the processing table 1. The driven gear 373 is meshed with the lower part of the driven gear 372. The center of the two driven gears 373 is fixedly connected with a transmission shaft 374. The transmission shaft 374 passes through and is rotatably connected to the processing table 1.

[0028] The cam 372 is engaged with the gear 373 and the gear 374 is engaged with the gear 376. The cam 372 is engaged with the gear 377 and the gear 378 is engaged with the gear 379. The cam 373 is engaged with the gear 371 and the gear 379 is engaged with the gear 371.

[0029] Please see the attached Figure 5 The driving end of the motor 4 is connected to the lower conveyor roller 2 through the conveying assembly 8 to drive the lower conveyor roller 2 to rotate. The conveying assembly 8 includes a plurality of driven sprockets 81 and a driving sprocket 82. The driving sprocket 82 is fixedly mounted on the outer wall of the driving end of the motor 4. The driven sprocket 81 is fixedly mounted on the outer wall of one end of the lower conveyor roller 2. The driven sprocket 81 and the driving sprocket 82 are meshed and connected with a chain 83.

[0030] Specifically, the operation of motor 14 drives the active sprocket 82 to rotate, the active sprocket 82 drives the chain 83 to rotate, the chain 83 drives multiple driven sprockets 81 to rotate, and the driven sprocket 81 drives the lower conveying roller 2 to rotate. Then, when the motor 14 rotates forward, the lower conveying roller 2 is driven to rotate and the PVC board 7 is moved from the grinding disc 33 to the grinding roller 31. When the motor 14 is reversed, the lower conveying roller 2 conveys the rotated PVC board 7 in the reverse direction through the grinding disc 33 for grinding. The operation of motor 14 can realize the grinding and conveying of the board, and no additional conveying equipment is required to convey the PVC board 7, thereby reducing equipment investment and reducing costs.

[0031] Please see the attached Figure 3 The conveying assembly 8 includes two groups of upper conveying rollers 84. The upper conveying rollers 84 are arranged directly above the lower conveying roller 2. The same ends of the adjacent upper conveying rollers 84 and lower conveying rollers 2 are fixedly connected with transmission gears 2 85, and the two transmission gears 2 85 are meshed and connected.

[0032] Specifically, the two groups of upper conveying rollers 84 are respectively located on both sides of the grinding roller 31. When the lower conveying roller 2 rotates, the upper conveying roller 84 is driven to rotate in the opposite direction through the transmission gear 2 85. The friction between the upper conveying roller 84 and the lower conveying roller 2 and the surface of the plate can assist the PVC plate 7 to move through the grinding disc 33 for grinding. At the same time, the PVC plate 7 is limited during grinding to prevent the PVC plate 7 from shaking up and down.

[0033] Embodiment 2: This embodiment provides another structure in the above embodiment: Motor 1 4 adopts a dual-axis motor. The output shaft at one end of the dual-axis motor is connected to the one-way clutch 10 and the driving mechanism 37 to drive the grinding roller 31 and the grinding disc 33 to rotate, and the other output shaft of the dual-axis motor is connected to the reducer. The output shaft of the reducer is connected to the driving sprocket 82, so that the conveying speed of the lower conveying roller 2 and the upper conveying roller 84 is reduced by the reducer.

[0034] Please see the attached Figure 7 -Attached Figure 8 The rotating assembly 6 includes a cylinder 61, which is fixedly mounted at the center of the mounting frame 5. The driving end of the cylinder 61 is fixedly connected to the rotating frame 62. The center of the lower surface of the rotating frame 62 is fixedly connected to a motor 2 63. The motor 2 63 adopts a servo motor. The driving end of the motor 2 63 is fixedly connected to a telescopic transmission rod 64. The bottom end of the telescopic transmission rod 64 is higher than the PVC board 7. The bottom end of the telescopic transmission rod 64 is installed with a splint 65. The splint 65 includes a slide 651. The lower cylinder of the telescopic transmission rod 64 is fixedly connected to the slide 651. Slide grooves are respectively provided on both sides of the slide 651. The inside of the slide is slidably connected with a clamping plate 652. The clamping plate 652 is located in the gap of the lower conveying roller 2. The surface of the clamping plate 652 is installed with a spacing adjustment mechanism 653 for adjusting the spacing between the two clamping plates 652. The bottom end of the clamping plate 652 is higher than the vertex of the lower conveying roller 2.

[0035] Specifically, after the initial polishing, the PVC board 7 is transported to the bottom of the splint 65, and the positions of the two clamping plates 652 are adjusted according to the size of the PVC board 7 through the spacing adjustment mechanism 653, so that the two clamping plates 652 are against the side walls of the PVC board 7, and then the telescopic transmission rod 64 is driven to rotate by the motor 2 63, and the telescopic transmission rod 64 drives the splint 65 to rotate, and the splint 65 pushes the PVC board 7 to rotate, thereby achieving the effect of turning the PVC board 7 to adjust its side to be polished.

[0036] Please see the attached Figure 9The spacing adjustment mechanism 653 includes two rotating parts 6531, the bottom end of the rotating part 6531 is rotatably connected to the upper side wall of the clamping plate 652, the top of the two rotating parts 6531 is rotatably connected to a rotating ring 6532, the inner wall of the rotating ring 6532 is rotatably connected to the outer wall of the rotating frame 62, and the two ends of the slide 651 are slidably connected to a ring-shaped support frame 6533, and the outer end of the support frame 6533 is fixedly connected to the inner wall of the processing table 1.

[0037] Specifically, the support frame 6533 is used to support and limit the slide 651 for rotation. When the spacing of the clamping plates 652 needs to be adjusted, the height of the rotating ring 6532 is adjusted by extending the cylinder 61. The rotating ring 6532 moves through the rotating member 6531 to push the clamping plate 652 to slide inside the slide groove, so that when the cylinder 61 contracts and drives the rotating ring 6532 to rise, the clamping plate 652 is pulled open by the rotating member 6531. When the cylinder 61 extends and drives the rotating ring 6532 to descend, the clamping plate 652 is pushed against the PVC plate 7 by the rotating member 6531 to clamp and limit, so as to achieve the effect of adjusting the spacing of the clamping plates 652 according to the size of the PVC plate 7. When the PVC plate 7 is polished for the second time and is transported to the rotating assembly 6 again, the PVC plate 7 is clamped again by the clamping plate 652. At this time, the PVC plate 7 is driven to rotate for a certain period of time by the motor 2 63, so that the debris remaining from the polishing on the surface of the PVC plate 7 can be thrown out, thereby cleaning the PVC plate 7.

[0038] Please see the attached Figure 9 The upper side wall of the clamping plate 652 is fixedly connected to an elastic member 6534, and one end of the elastic member 6534 away from the clamping plate 652 is fixedly connected to the inner side wall of the sliding groove.

[0039] Specifically, the elastic member 1 6534 is used to apply elastic force to the clamping plate 652, and when the rotating member 6531 pulls the clamping plate 652 to open, it assists the clamping plate 652 to slide outward better.

[0040] For example three, please refer to the attached Figure 10 Since the PVC board 7 is placed on the lower conveying roller 2, when the PVC board 7 rotates to clean the debris, it will cause friction with the lower conveying roller 2 and cause wear. Therefore, this embodiment provides another structure in the above embodiment: The clamping plate 652 includes a connecting seat 6521, a groove is provided inside the connecting seat 6521, and obliquely arranged strip-shaped guide holes 6522 are provided on both sides of the groove. A clamping piece 6523 is provided below the groove, and the clamping piece 6523 is obliquely slidably connected to the connecting seat 6521, and the sliding direction is consistent with the guide hole 6522. The two sides of the clamping piece 6523 are fixedly connected to the limiting shaft 6524, and the limiting shaft 6524 passes through the guide hole 6522. The top of the clamping piece 6523 is fixedly connected to the elastic piece 2 6525, and the top of the elastic piece 2 6525 is fixedly connected to the inner side wall of the groove. The bottom end of the clamping piece 6523 is fixedly connected to the lower support plate 6527, and an upper clamping plate 6526 is provided above the lower support plate 6527. One end of the upper clamping plate 6526 is fixedly connected to the side wall of the clamping piece 6523.

[0041] Specifically, elastic force is applied to the clamping member 6523 by the second elastic member 6525, so that the limiting shaft 6524 slides to the bottom end of the guide hole 6522. At this time, the upper surface of the lower support plate 6527 is kept level with the lower surface of the PVC board 7, and the lower surface of the upper clamping edge is kept level with the upper surface of the PVC board 7. Then, when the clamping plate 652 moves to press against the PVC board 7, the PVC board 7 is inserted between the lower support plate 6527 and the upper clamping plate 6526, and drives the limiting shaft 6524 to slide upward to the top along the guide hole 6522, thereby raising the height of the clamping member 6523, so that the lower support plate 6527 is higher than the lower conveying roller 2 to avoid motion interference, and the height of the PVC board 7 is raised to keep it suspended and rotating, to avoid friction with the lower conveying roller 2 and wear.

[0042] Please see the attached Figure 10 An L-shaped lifting frame 6528 is provided on both sides of the clamping plate 652. The lifting frame 6528 is fixedly installed on the lower surface of the four corners of the slide 651. An annular groove 9 is provided at the center of the lower conveying roller 2. The setting of the annular groove 9 prevents the lower support plate 6527 from interfering with the lower conveying roller 2 when moving. The bottom end of the lifting frame 6528 is provided with an inclined surface for the movement of the limit shaft 6524.

[0043] Specifically, when the clamping plate 65 adjusts the angle of the PVC board 7 for secondary grinding, the clamping plate 652 drives the PVC board 7 to rotate 90° and move to the annular groove 9. At this time, the two clamping plates 652 are moved in opposite directions by the contraction of the cylinder 61. The movement of the clamping plate 652 drives the limit shaft 6524 to move, so that the lifting frame 6528 moves upward along the inclined surface of the lifting frame 6528, thereby automatically raising the height of the lower support plate 6527, so that the bottom end of the lower support plate 6527 is higher than the PVC board 7, avoiding affecting the reverse movement of the PVC board 7 for secondary grinding.

[0044] Please see the attached Figure 7The outlet of the processing table 1 is connected to a baffle 12 by an axis rotation. The baffle 12 is used to block the debris thrown out when the PVC board 7 rotates, so as to prevent the debris from being thrown out from the outlet.

[0045] Working process: When it is necessary to process the PVC door, the PVC board 7 is placed on the lower conveyor roller 2, and the lower conveyor roller 2 conveys the PVC board 7 through the grinding roller 31. The motor 4 is operated and the one-way clutch 10 is used to drive the lower grinding roller 31 to rotate. The lower grinding roller 31 drives the connected transmission gear 1 32 to rotate. The transmission gear 1 32 drives another transmission gear 1 32 to rotate in the opposite direction. The other transmission gear 1 32 drives the upper grinding roller 31 to rotate, so that the motor 1 4 drives the two groups of grinding rollers 31 to rotate synchronously. The upper and lower surfaces of the PVC board 7 are polished respectively by the two groups of grinding rollers 31, and the grinding disc 33 is pushed to move relative to each other by the electric push cylinder 35, so that the spacing between the two grinding discs 33 is the same as the width of the PVC board 7. When the motor 4 is running, the connecting rod 34 is driven to rotate through the driving mechanism 37, so that the grinding disc 33 rotates, and then the left and right sides of the PVC board 7 are ground. After the PVC board 7 moves to the bottom of the rotating component 6, the electric push cylinder 35 is contracted so that the distance between the two grinding discs 33 is the same as the length of the PVC board 7. After the PVC board 7 is driven by the rotating component 6 to rotate 90 degrees, the PVC board 7 is reversely conveyed through the grinding disc 33. At this time, the left and right sides of the rotated PVC board 7 can be ground, thereby achieving all-round grinding of the PVC board 7, quickly removing burrs and flash on the edges and surfaces of the PVC board 7, and improving the production and processing efficiency of the PVC board 7. Finally, after the grinding is completed, it is transported away by the lower conveying roller 2.

[0046] The PVC board 7 needs to be conveyed to the bottom of the clamping plate 65 after the initial grinding. The positions of the two clamping plates 652 are adjusted according to the size of the PVC board 7 through the spacing adjustment mechanism 653, so that the two clamping plates 652 are against the side walls of the PVC board 7. Then, the telescopic transmission rod 64 is driven to rotate by the motor 2 63, and the telescopic transmission rod 64 drives the clamping plate 65 to rotate. The clamping plate 65 pushes the PVC board 7 to rotate, thereby achieving the effect of steering and adjusting the side of the PVC board 7 to be grinded. When the PVC board 7 is polished for the second time and is conveyed to the rotating component 6 again, the PVC board 7 is clamped again by the clamping plate 652. At this time, the PVC board 7 is driven to rotate for a certain period of time by the motor 2 63, so that the debris remaining on the surface of the PVC board 7 from grinding can be thrown out, thereby cleaning the PVC board 7.
