Description

Technical Field

[0001] The utility model belongs to the technical field of plastic pallet production, in particular to a sheet machine uniform material spreading device for plastic pallet production. Background Art

[0002] Sheet molded plastic is a new type of thermosetting molded plastic, which is widely used in various fields such as transportation, construction, and electrical appliances, and has broad development prospects. Before the existing sheet machine is produced and processed, a conveying device is required to transport the reacted materials to the sheet machine. During the conveying process, in order to avoid excessive accumulation of materials and blockage of the feed port, and to ensure the smooth progress of production and processing, the materials need to be spread evenly. After searching, the patent with application number 202221998020.9 discloses a uniform spreading device for sheet machines for plastic pallet production, including a pre-pressing mechanism, and a rolling mechanism is arranged outside the pre-pressing mechanism; the pre-pressing mechanism includes a support seat, a fixed block is fixedly connected to one end of the outer side of the support seat, a conveyor belt is arranged inside the fixed block, a side fixing plate is fixedly connected to the middle part of the support seat, a crossbeam is fixedly connected to the upper end of the side fixing plate, a lifting pump is fixedly connected to the bottom surface of the crossbeam, and a pressure plate is arranged at the lower end of the lifting pump.

[0003] However, during actual use, the applicant found that the two ends of the rotating roller are arranged on two sliders, and the tops of the two sliders are rotatably connected to screws. When the position and height of the rotating roller need to be adjusted during use, personnel are required to manually adjust the two screws. Since the two screws are independently arranged, the two screws cannot be accurately adjusted synchronously, which makes it inconvenient for personnel to quickly and flexibly adjust the position and height of the rotating roller. In view of this, we propose a uniform spreading device for a sheet machine for producing plastic pallets. Utility Model Content
