[0025] Adjusting mechanism, the adjusting mechanism is arranged on the unloading frame body 1, the adjusting mechanism includes a plurality of moving plates 5 and a plurality of connecting plates 6, a moving groove 8 is formed on each supporting plate 4, and the plurality of moving plates 5 are respectively slidably installed on the inner walls of the plurality of moving grooves 8. Each connecting plate 6 is fixedly installed on the front surface of every two moving grooves 8, and two rectangular plates 7 are fixedly installed on the upper surface of each connecting plate 6.

[0026] Furthermore, the adjusting mechanism further includes a plurality of intercepting boxes 9, a plurality of second electric telescopic rods 10 and a plurality of limiting plates 11. Each intercepting box 9 is slidably installed on the outer surface of each rectangular plate 7. Each second electric telescopic rod 10 is fixedly installed on the upper surface of each rectangular plate 7. The telescopic end of each second electric telescopic rod 10 is fixedly connected to the corresponding intercepting box 9. A limiting groove 12 is formed on the lower surface of each moving groove 8, and each limiting plate 11 is slidably installed inside each limiting groove 12. Each limiting plate 11 is fixedly connected to the corresponding moving plate 5.

[0027] Furthermore, the second electric telescopic rod 10 drives the intercepting box 9 to move upward, so that the intercepting box 9 can block the large-diameter PVC pipes, preventing the large-diameter PVC pipes from lacking blocking objects when falling onto the supporting plate 4, thus rolling out and causing damage, reducing the damage rate of the PVC pipes, further improving the applicable range of the supporting and unloading frame, and improving the production efficiency of the PVC pipes.

[0028] Furthermore, an installation groove 13 is formed inside the unloading frame body 1. A motor 14 is fixedly installed on the unloading frame body 1. The output end of the motor 14 rotates through the inside of the installation groove 13. A threaded rod 15 is rotatably installed on the unloading frame body 1 corresponding to each connecting plate 6. The front ends of the plurality of threaded rods 15 all rotatably extend into the inside of the installation groove 13.

[0029] Furthermore, a rotating rod 16 is rotatably installed inside the installation groove 13. The output end of the motor 14 and the front ends of the plurality of threaded rods 15 are all fixedly installed with a first bevel gear 17. A second bevel gear 18 is fixedly installed on the outer surface of the rotating rod 16 corresponding to the positions of the plurality of first bevel gears 17. The second bevel gear 18 is meshed with the corresponding first bevel gear 17.

[0030] Furthermore, a sliding plate 19 is threadedly connected to the outer surfaces of the plurality of threaded rods 15. Each sliding plate 19 is slidably connected to the inner wall of the unloading frame body 1. An L-shaped connecting plate 20 is fixedly installed on the upper surface of each sliding plate 19. The upper end of the L-shaped connecting plate 20 is fixedly connected to the corresponding connecting plate 6.

[0031] Furthermore, the motor 14 drives multiple connecting plates 6 to move forward, thereby causing multiple moving plates 5 to move forward, and enabling the limiting plate 11 to limit the moving plate 5 inside the limiting groove 12, preventing the moving plate 5 and the connecting plate 6 from tipping forward during movement, thereby improving the practicability of the device, increasing the accommodating space of the supporting plate 4, expanding the applicable range of the supporting and unloading rack, and thus improving its working efficiency.

[0032] Furthermore, the number of multiple connecting plates 6 is one-half of the number of multiple moving grooves 8, and the number of multiple supporting plates 4 is the same as that of multiple moving plates 5.

[0033] Working principle: When using this device to support and unload PVC pipes, when the number of PVC pipes is large, the motor 14 can be started. The output end of the motor 14 rotates, driving the first bevel gear 17 fixedly connected to the output end of the motor 14 to start rotating. The second bevel gear 18 meshed with the first bevel gear 17 on the motor 14 starts to rotate. At this time, the rotating rod 16 fixedly connected to the second bevel gear 18 starts to rotate, so that multiple second bevel gears 18 fixedly installed on the rotating rod 16 rotate simultaneously, thereby driving multiple first bevel gears 17 meshed with the multiple second bevel gears 18 to rotate. The rotation of the remaining multiple first bevel gears 17 drives the threaded rods 15 fixedly connected thereto to rotate, so that the sliding plates 19 threadedly connected to the outer surfaces of the multiple threaded rods 15 move forward. The multiple sliding plates 19 move forward, so that the L-shaped connecting plates 20 fixedly installed on the sliding plates 19 move synchronously. The L-shaped connecting plate 20 moves forward, driving the connecting plate 6 fixedly connected to the upper end of the L-shaped connecting plate 20 to move forward, thereby causing the connecting plate 6 to drive the moving plate 5 fixedly connected thereto to move inside the moving groove 8. The limiting plate 11 fixedly installed on the lower surface of the moving plate 5 moves synchronously inside the limiting groove 12. When the limiting plate 11 moves to the front inner wall of the limiting groove 12, the motor 14 stops. At this time, the moving plate 5 moves forward a certain distance from the corresponding moving groove 8. The rectangular plate 7 fixedly installed on the connecting plate 6 and the intercepting box 9 slidably installed on the outer surface of the rectangular plate 7 move synchronously, so that the supporting space on the supporting plate 4 becomes larger and can accommodate a larger number of PVC pipes. When it is necessary to support large-diameter PVC pipes, the second electric telescopic rod 10 can also be started to drive the intercepting box 9 fixedly connected to its telescopic end to move upward, so that the intercepting box 9 can block the large-diameter PVC pipes, so that the large-diameter PVC pipes remain on the supporting plate 4, preventing the large-diameter PVC pipes from rolling down and causing damage.

[0034] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
