Description

Technical Field

[0001] The invention belongs to the technical field of production and processing of artificial boards, and in particular relates to a needle threading structure with an exhaust channel for a double steel belt continuous flat press. Background Art

[0002] At present, the double steel belt continuous flat press used for producing artificial boards consists of an upper press, a lower press, and a continuously circulating steel belt respectively wrapped around the upper press and the lower press. Rollers that can move continuously are evenly distributed between the hot pressing plates and the steel belts at the upper and lower presses. The transmission of the rollers is driven by chains. The chains travel in chain brackets. The chain brackets are equivalent to the tracks of the chains, and the two brackets are not parallel. They gradually spread in the direction of travel in the pressurized area and gradually tighten on the way back. Therefore, the needle will make a piston movement as the chain circles the press for one week, which is used to The lubricating oil is introduced between the roller rod and the threading needle. The roller rod is connected to the roller rod chain at both ends with a predetermined movable gap by means of the threading needles at both ends, and is guided on a specified circulation path. However, in the above design, in the tightening range, as the speed increases, the gas in the roller rod hole will not be discharged in time, causing the gas to exert a certain pressure on the threading needle, pushing the threading needle to move outward, and the threading needle drives the chain to move outward. The chain bracket is fixed, so the chain exerts a certain compressive stress on the side of the chain bracket, thereby wearing the chain bracket and reducing the service life of the chain bracket. Therefore, it is necessary to improve the existing technology to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to provide a needle threading structure with an exhaust channel for a double steel belt continuous flat press. By setting the exhaust slot on the needle threading body, the air in the slot can be discharged in time when the needle threading body moves back and forth, thereby solving the problem that the air in the slots at both ends of the roller rod cannot be discharged in time when the existing double steel belt continuous flat press is working.

[0009] The V-shaped fixing frame passes through the rectangular through slots arranged in alignment on the two side plates in sequence, and the limiting slot is engaged in a rectangular through slot far away from the plug column.

[0010] Furthermore, the first chain assembly and the second chain assembly are alternately arranged to form a chain body, one end of the second chain assembly is slidably inserted into one end of an adjacent first chain assembly, and adjacent through holes of the first chain assembly and the second chain assembly are overlapped.

[0011] Furthermore, the first chain assembly and the second chain assembly are connected by means of a fixing column through the overlapping through holes, and both ends of the fixing column extend to the outside of the first chain assembly and are fixedly connected to the limiting plate.
