Description

Technical Field

[0001] The invention relates to the technical field of film-faced plywood production, in particular to a lifting device used for film-faced plywood production. Background Art

[0002] Film faced plywood is usually made of multiple glued layers (veneers) bonded together with glue to form a board with high strength and stability. It is covered with a film, usually polyester, polyvinyl chloride (PVC) or other synthetic materials, to provide additional protection.

[0003] In the prior art, a Chinese patent with publication number "CN211338490U" discloses a plate lifting device. When the plate is placed at an angle, a person can first start a driving device to drive the main beam to rotate. The main beam rotates in the connecting arm to drive the longitudinal beam and the suction cup connected to the longitudinal beam to rotate, thereby changing the suction and lifting plane of the suction cup to adapt to plates in different upright directions. The device has stronger adaptability and solves the problem that the plates to be lifted in the workshop are sometimes placed at an angle. Therefore, the installation fixing seat needs to be manually flipped during the lifting process so that each suction cup can contact the surface of the plate to suck it up. When the fixing seat is large, its weight is heavy, so manual flipping is difficult and safety accidents are prone to occur.

[0004] At present, in the process of producing film-faced plywood, since most of the plywood sheets are piled together, and the plywood sheets are usually heavy and large in size, if they are carried manually, it is not only laborious but also easy to cause injuries to the carryers. At the same time, the efficiency of manual carrying is low, which seriously affects the efficiency of the film-faced plywood. Therefore, when carrying the plywood, most of them are carried by lifting equipment. However, most of the current lifting equipment uses a lifting machine to drive a hanging plate, and uses a clamping mechanism on the hanging plate to clamp the plywood. However, the clamping mechanism can only clamp the side end surface of the plywood. When the friction between the clamping plate in the clamping mechanism and the plywood is small, the clamped plywood is easy to fall off. Therefore, the present invention proposes a lifting equipment for the production of film-faced plywood to solve the above-mentioned problems. Summary of the invention

[0039] In this embodiment, when the clamping plate 4 moves inward, the lifting plate 20 in the lifting groove 18 will move upward by being pulled by the driving rod 16. By using the driving gear block 24 on the lifting plate 20 and the auxiliary gear 23 in cooperation, the auxiliary gear 23 will drive the bottom support plate 25 to rotate through the driving shaft 22 when rotating. After the rotation, the bottom support plate 25 can fit the bottom of the cardboard, thereby increasing the stability of the cardboard during the lifting process.

[0040] Embodiment three:

[0041] See also Figure 1-8The pressing assembly is provided with a top fixing assembly, which facilitates the pressing of the clamped and lifted cardboard. The top fixing assembly includes a mounting tube 26 fixedly mounted on the hanging plate 1, an upper slide plate 27 and a lower slide plate 28 are slidably connected inside the mounting tube 26, an upper ejector rod 29 is fixedly mounted on the upper slide plate 27, an end of the upper ejector rod 29 away from the upper slide plate 27 extends to the outside of the mounting tube 26 and is fixedly connected to the lower pressing plate 6, a lower ejector rod 30 is fixedly mounted on the lower slide plate 28, and the lower ejector rod 30 is away from the lower One end of the pressure plate 6 passes through the mounting tube 26 and the hanging plate 1 in sequence, and is fixedly installed with a top fixing plate 31. A reset spring 32 is fixedly connected to the upper end surface of the top fixing plate 31. The end of the reset spring 32 away from the top fixing plate 31 is fixedly connected to the hanging plate 1. An auxiliary spring 33 is fixedly installed on the lower end surface of the upper slide plate 27. The end of the auxiliary spring 33 away from the upper slide plate 27 is fixedly connected to the lower slide plate 28. The auxiliary spring 33 is used to restore the top fixing plate 31 that has changed its position to its original position.

[0042] In this embodiment, when the lower pressing plate 6 descends, the lower pressing plate 6 will synchronously drive the upper slide plate 27 on the upper ejector rod 29 to slide in the mounting tube 26, and the thrust generated by the upper slide plate 27 will act on the lower slide plate 28 through the auxiliary spring 33. By utilizing the reaction force of the auxiliary spring 33, the lower slide plate 28 drives the top fixing plate 31 to fit onto the upper end surface of the paperboard through the lower ejector rod 30, thereby effectively providing additional stability to the paperboard.

[0043] Working principle:

[0044] When in use, the lower pressing plate 6 is driven to descend by the hydraulic cylinder 5, and the rotating plate 8 connected through the mounting groove 7 will synchronously follow the lower pressing plate 6 to descend. The rotating plate 8 in the descending state will slide in the limiting groove 11 on the V-shaped plate 10 through the limiting shaft 9, so that the rotating plate 8 rotates inwardly with the mounting groove 7 as the center. The rotating plate 8 will slide in the sliding groove 12 through the sliding block 13, thereby driving the clamping plate 4 to move inwardly, and the cardboard can be clamped and fixed by the clamping plate 4 to ensure the stability of the cardboard when it is hoisted;

[0045] When the clamping plate 4 moves inward, the lifting plate 20 in the lifting groove 18 will move upward by being pulled by the driving rod 16. The driving gear block 24 on the lifting plate 20 cooperates with the auxiliary gear 23. When the auxiliary gear 23 rotates, it drives the bottom support plate 25 to rotate through the driving shaft 22. After the rotation, the bottom support plate 25 can be attached to the bottom of the paperboard, thereby increasing the stability of the paperboard during the lifting process.

[0046] When the lower pressing plate 6 descends, the lower pressing plate 6 will synchronously drive the upper slide plate 27 on the upper ejector rod 29 to slide in the mounting tube 26, and the thrust generated by the upper slide plate 27 will act on the lower slide plate 28 through the auxiliary spring 33. The reaction force of the auxiliary spring 33 will make the lower slide plate 28 drive the top fixing plate 31 to fit on the upper end surface of the paperboard through the lower ejector rod 30, effectively providing additional stability for the paperboard;

[0047] When the cardboard is transported, the hydraulic cylinder 5 is used to drive the lower pressing plate 6 to rise, and the clamping plate 4 and the bottom supporting plate 25 will return to their original positions. At the same time, the top fixing plate 31 will return to its original position through the elastic force of the reset tension spring 32.

[0048] In the present technical solution, protective pads can be provided on the clamping plate 4, the bottom support plate 25 and the top fixing plate 31 according to the needs of personnel, and the protective pads are used to prevent the clamping plate 4, the bottom support plate 25 and the top fixing plate 31 from causing damage to the cardboard. At the same time, the friction between the clamping plate 4, the bottom support plate 25, the top fixing plate 31 and the cardboard can also be increased, thereby improving the stability of the cardboard during the lifting process.

[0049] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0050] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the invention.
