Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of horizontal filter press plate production, in particular to a material turning mechanism. Background Art
[0002] At present, the production of large horizontal filter plates has always relied on the molding process. This process is basically still based on manual operation. The single filter plate area of the super horizontal filter press products currently developed is more than 2m×2m. After several batching trials, some problems were found, especially in the material turning and exhausting process. At present, the production of large horizontal filter plates in China basically adopts manual turning by a group of 3-4 people. For hundreds of kilograms of high-viscosity and high-strength engineering PP that piles up like a mountain after melting, it is a huge challenge to human physical strength to rely on a few people to turn the materials and exhaust in the mold. And because of the size of the manpower, the turning of the materials cannot be coordinated and synchronized, and the PP melt is unevenly stirred, resulting in local crystallization and hardening on the surface, resulting in the defect of cold marks on the molded products. It has a great impact on quality. In the current situation of human resource shortage in society, it is also a challenge that must be faced to form mass production in the future.

DETAILED DESCRIPTION
[0013] In order to more thoroughly understand the features and technical contents of the present invention, the implementation of the present invention is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not intended to limit the present invention.
[0014] like Figure 1 As shown, a material turning mechanism includes a grabbing mechanism 1, a lifting mechanism 2, a walking mechanism 3, and a PCL master control system. The grabbing mechanism 1 includes a grab shovel 11, a grab arm 12, a fixed frame 13, a small oil cylinder 14 and a first proximity switch 15. The lifting mechanism 2 includes a multi-section cylinder 21, a guide rod 22, a second proximity switch 23, and a hydraulic station 24. The walking mechanism 3 includes a moving beam 31, a driving walking motor 31, a rotary encoder 33, a track 34, and an I-beam beam 35. The grab shovel 11 is connected to the grab arm 12, and the grab arm 12 is connected to the small oil cylinder 14 through a connecting pin 16. A first proximity switch 15 is fixed below the small oil cylinder 14. The lifting mechanism 2 is connected to the moving beam 31, and the second proximity switch 23 is located on one side of the guide rod 22. The moving beam 31 is connected to the track 34, and the track 34 is located on the I-beam beam 35.
[0015] Preferably, the embodiment of the utility model further includes a manual operating system, and the manual mode controls the grabbing mechanism 1, the lifting mechanism 2 and the walking mechanism 3 by operating corresponding buttons of the manual operating system.
[0016] The opening and closing of the grab arm 12 of the grabbing mechanism 1 is controlled by the small oil cylinder 14. The grab arm 12 is designed to be normally open. The grab shovel 11 and the grab arm 12 are softly connected, which is beneficial to avoid hard friction with the mold cavity during the grabbing process and damage to the mold. When the lifting mechanism 2 descends to the preset height in the PLC master control system, the second proximity switch 23 of the lifting mechanism 2 receives a signal and transmits it to the PLC master control system, controlling the small oil cylinder 14 to open and the grab arm 12 to slowly close, so as to achieve the closed grabbing of the grab shovel 11. When the small oil cylinder 14 is opened to a certain position, the grab arm 12 is closed, and the first proximity switch 15 receives a signal and transmits it to the PLC master control system. The lower section of the multi-section cylinder 21 of the lifting structure 2 is filled with liquid, so that the lifting mechanism 2 and the material on the shovel claw go up to a certain height, and then the driving travel motor 31 is started, and the moving beam 31 loaded with the lifting mechanism 2 moves along the track 34. The travel distance of the moving beam 31 is preset in the PLC master control system, and the rotary encoder 33 transmits the signal to the PLC master control system to realize the start and stop of the driving travel motor 31. When the moving beam 31 travels to the preset distance, the PLC master control system controls the hydraulic station 24 to work to open the grab arm 12, and the material falls. The PLC master control system controls the moving beam 31 to move in the opposite direction and return to the initial position. Repeat the above action and flip it back and forth 3 times to complete the material flipping.
