Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a medium density fiberboard conveying mechanism is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A medium - density fiberboard conveying mechanism includes a roller conveyor supported on the ground by a support frame. At both ends of the support frame, a first limiting and guiding assembly is relatively arranged. Between the two first limiting and guiding assemblies, a second limiting and guiding assembly is arranged. Both the first limiting and guiding assembly and the second limiting and guiding assembly are located between the conveying rollers of the roller conveyor.

[0027] Embodiment 1

[0028] A medium density fiberboard conveying mechanism, as Figures 1 to 3 shown, includes a roller conveyor 2 supported on the ground by a support frame 1. The roller conveyor 2 can have the same structure as the combined structure of the left conveyor and the right conveyor in Chinese Patent Publication No. CN108001942A. At both ends of the support frame 1, a first limiting and guiding component 3 is relatively arranged. A second limiting and guiding component 4 is arranged between the two first limiting and guiding components 3. Both the first limiting and guiding component 3 and the second limiting and guiding component 4 are located between the conveying rollers of the roller conveyor 2. The first limiting and guiding component 3 includes a connecting groove 5 and a fixing frame 6. The connecting groove 5 is opened on the side wall of the support frame 1. The fixing frame 6 is slidably matched with the inner wall of the connecting groove 5. A limiting wheel 7 is rotatably connected to the inner wall of the fixing frame 6. A guiding rod 8 is fixed to the outer wall of one side of the fixing frame 6. The guiding rod 8 is slidably connected with the support frame 1. A threaded rod 9 is rotatably connected to the outer wall of one side of the fixing frame 6. The other end of the threaded rod 9 is connected with a handwheel 10. The threaded rod 9 is in threaded cooperation with the support frame 1. The second limiting and guiding component 4 has the same combination of a connecting groove 5, a fixing frame 6, a limiting wheel 7 and a guiding rod 8 as the support frame 1. The difference between the second limiting and guiding component 4 and the first limiting and guiding component 3 is that: a connecting rod 12 is fixed to one side of the fixing frame 6 of the second limiting and guiding component 4. The connecting rod 12 is slidably matched with the support frame 1. A plurality of the connecting rods 12 are connected with the threaded rod 9 through a linkage rod 11. An installation plate 14 is fixed to the outer wall of the support frame 1. The installation plate 14 is located on one side of the threaded rod 9. A plurality of limiting grooves 13 are opened on the outer wall of the threaded rod 9. One end of the installation plate 14 is slidably connected with a pull rod 15. One end of the pull rod 15 is in limiting cooperation with the limiting groove 13. A return spring 16 is sleeved on the outer wall of one end of the pull rod 15. The two ends of the return spring 16 are respectively connected with the pull rod 15 and the installation plate 14.

[0029] During the transportation of the fiberboard, both sides of the fiberboard are in contact with the surface of the limit wheel 7, and the limit wheel 7 limits the fiberboard. Since the limit wheel 7 is rotatably connected to the fixed frame 6, the friction between the limit wheel 7 and the limit plate is rolling friction, and the friction force is small, which avoids the wear of the fiberboard caused by the limit wheel 7. When the width of the transported fiberboard changes, the threaded rods 9 of the limit guiding assembly 1 at both ends of the support frame 1 are rotated respectively to push the fixed frame 6 to move, changing the distance between the limit wheels 7 on both sides of the support frame 1. When the threaded rod 9 pushes the fixed frame 6 in the limit guiding assembly 1 to move, the linkage rod 11 will move along with the threaded rod 9, and drive the fixed frame 6 in the limit guiding assembly 2 to move through the connecting rod 12, so that the limit wheel 7 in the limit guiding assembly 2 and the limit wheel 7 in the limit guiding assembly 1 are on the same horizontal line.

[0030] By setting the limit guiding assembly 1 and the limit guiding assembly 2, during the transportation of the fiberboard, both sides of the fiberboard are in contact with the surface of the limit wheel 7, and the limit wheel 7 limits the fiberboard. Since the limit wheel 7 is rotatably connected to the fixed frame 6, the friction between the limit wheel 7 and the limit plate is rolling friction, and the friction force is small, which avoids the wear of the fiberboard caused by the limit wheel 7.

[0031] By setting the linkage rod 11 and the connecting rod 12, when the width of the transported fiberboard changes, the threaded rods 9 of the limit guiding assembly 1 at both ends of the support frame 1 are rotated respectively. The linkage rod 11 will move along with the threaded rod 9, and drive the fixed frame 6 in the limit guiding assembly 2 to move through the connecting rod 12, so that the limit wheel 7 in the limit guiding assembly 2 and the limit wheel 7 in the limit guiding assembly 1 are on the same horizontal line, reducing the operations required for adjustment and facilitating adjustment.

[0032] Embodiment 2

[0033] A medium density fiberboard conveying mechanism. On the basis of Embodiment 1, the following improvements are made as Figure 1 、 Figure 4 shown. A linear driving mechanism 17 is arranged at the bottom end of the support frame 1. The linear driving mechanism 17 can be a combined structure of a motor and a lead screw or other linear motion structures. The top end of the linear driving mechanism 17 is connected with a mounting frame 18. The inner wall of the top end of the mounting frame 18 is rotatably connected with a cleaning wheel 19. The cleaning wheel 19 is in contact and cooperation with the outer wall of the bottom end of the conveying roller of the roller conveyor 2. A collection box 20 is arranged on the inner wall of the bottom end of the mounting frame 18. Rotating wheels 21 are arranged on the outer walls of both ends of the rotating shaft of the cleaning wheel 19. The rotating wheels 21 are in contact and cooperation with the outer wall of the support frame 1.

[0034] During the operation of the device, the linear drive mechanism 17 drives the mounting bracket 18 to reciprocate, drives the cleaning wheel 19 to rotate through the runner 21, the cleaning wheel 19 rubs against the surface of the conveying roller of the roller conveyor 2 relatively, cleans the surface of the conveying roller, and avoids impurities adhering to the surface of the conveying roller.

[0035] By arranging the linear drive mechanism 17, the mounting bracket 18, the cleaning wheel 19, the collection box 20 and the runner 21, during the operation of the device, the linear drive mechanism 17 drives the mounting bracket 18 to reciprocate, drives the cleaning wheel 19 to rotate through the runner 21, the cleaning wheel 19 rubs against the surface of the conveying roller of the roller conveyor 2 relatively, cleans the surface of the conveying roller, and avoids impurities adhering to the surface of the conveying roller.

[0036] Working principle: During the transportation of the fiberboard, both sides of the fiberboard contact the surface of the limit wheel 7, and the limit wheel 7 limits the fiberboard. Since the limit wheel 7 is rotatably connected to the fixed bracket 6, the friction between the limit wheel 7 and the limit plate is rolling friction, and the friction force is small, which avoids the wear of the fiberboard caused by the limit wheel 7. At the same time, the linear drive mechanism 17 drives the mounting bracket 18 to reciprocate, drives the cleaning wheel 19 to rotate through the runner 21, the cleaning wheel 19 rubs against the surface of the conveying roller of the roller conveyor 2 relatively, cleans the surface of the conveying roller, and avoids impurities adhering to the surface of the conveying roller; when the width of the conveyed fiberboard changes, rotate the threaded rods 9 of the limit guiding assembly 1 at both ends of the support frame 1 respectively, push the fixed bracket 6 to move, change the distance between the limit wheels 7 on both sides of the support frame 1. When the threaded rod 9 pushes the fixed bracket 6 in the limit guiding assembly 1 to move, the linkage rod 11 will move along with the threaded rod 9, drive the fixed bracket 6 in the limit guiding assembly 2 4 to move through the connecting rod 12, so that the limit wheel 7 in the limit guiding assembly 2 4 and the limit wheel 7 in the limit guiding assembly 1 are on the same horizontal line.

[0037] The above is only the preferred specific implementation mode of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
