Description

Technical Field

[0001] The utility model relates to the technical field of needle punching machines, and particularly relates to a needle punching machine with a pressure roller adjusting mechanism. Background Technique

[0002] A needle punching machine is a carpet-forming device that compacts and needles a refractory fiber blanket blank with a certain thickness to form a refractory fiber blanket. It repeatedly punctures a fiber web with needles having a triangular or other shaped cross-section and barbs on the edges. The fiber web discharged from a cross-laying or air-laying machine is very fluffy when fed into the needle punching machine. There is only a certain strength generated by the cohesion between fibers, but the strength is very poor. When multiple needles puncture the fiber web, the barbs on the needles will drive the fibers on the surface and sub-surface of the fiber web to move from the plane direction of the fiber web to the vertical direction of the fiber web, causing the fibers to shift up and down. The fibers that shift up and down exert a certain pressure on the fiber web, causing the fibers in the fiber web to approach and be compressed.

[0003] After retrieval, the existing Chinese patent publication number is: CN 218232753 U, which provides a needle punching machine with a pressure roller adjustment. This patent can freely adjust the distance between the pressure cloth roller and the surface of the conveyor belt through an adjustment mechanism, so as to adjust the distance between the pressure cloth roller and the conveyor belt according to factors such as the change in the gram weight of the non-woven fabric and the change in raw materials, ensure the pressing effect, and improve the processing quality.

[0004] Although the above patent can freely adjust the distance between the pressure cloth roller and the surface of the conveyor belt, and thus adjust the distance between the pressure cloth roller and the conveyor belt according to factors such as the change in the gram weight of the non-woven fabric and the change in raw materials to ensure the pressing effect, the above needle punching machine with a pressure roller adjustment still has the following problems: The pressure cloth roller is connected to the lifting seat, and thus it is very inconvenient to disassemble in the later stage, which affects the disassembly speed of the pressure cloth roller and further affects the maintenance speed in the later stage.

[0005] In view of the above problems, for this reason, a needle punching machine with a pressure roller adjusting mechanism is proposed. Content of the Utility Model

[0006] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art, and provide a needle punching machine with a pressure roller adjusting mechanism, which can solve the problems in the background technique.

[0007] To achieve the above object, the present utility model provides the following technical solution: A needle punching machine with a pressure roller adjusting mechanism, including a connecting frame. Inside the connecting frame, there is a conveyor belt. On the top of the connecting frame, a needle punching machine body is fixedly installed. On the top of the connecting frame, two fixing blocks are fixedly installed. The structures on the two fixing blocks are the same. Slideways are opened on both of the two fixing blocks. Inside both of the two slideways, a lifting seat is slidably connected. On the top of both of the two fixing blocks, an electric push rod is fixedly installed. The output ends of the two electric push rods respectively slide through the fixing blocks and extend into the interior of the fixing blocks. The output ends of the two electric push rods are respectively fixedly connected to the two lifting seats. Inside both of the two lifting seats, a rotating rod is rotatably connected. Polygonal grooves are opened on the opposite sides of the two rotating rods. Inside both of the two polygonal grooves, a connecting rod is slidably connected. A pressure cloth roller is slidably sleeved on the two connecting rods.

[0008] Preferably, two limiting plates are slidably connected inside the pressure cloth roller. The two limiting plates are respectively fixedly connected to the two connecting rods.

[0009] Preferably, elastic springs are fixedly installed on the opposite sides of the two limiting plates. Both of the two elastic springs are fixedly connected to the interior of the pressure cloth roller.

[0010] Preferably, a motor is fixedly installed on one of the lifting seats. The output end of the motor is fixedly connected to the rotating rod.

[0011] Preferably, brackets are fixedly installed on both of the two connecting rods. Inside both of the two brackets, a rotating wheel is rotatably connected.

[0012] Preferably, fixing bumps are fixedly installed on both of the two fixing blocks. The shapes of the two fixing bumps are both inclined.

[0013] Preferably, connecting plates are fixedly installed on both of the two lifting seats. On the opposite sides of the two connecting plates, a rotating shaft is rotatably connected. A scraping plate is fixedly sleeved on the rotating shaft.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] (1). For the needle punching machine with a press roller adjusting mechanism, push the two connecting rods so that they slide inside the cloth pressing roller. At the same time, the two limiting plates squeeze the two elastic springs, causing the two connecting rods to contract into the inside of the cloth pressing roller and disengage from the inside of the two polygonal grooves. Then, the cloth pressing roller can be removed from the connecting frame, which facilitates the installation and removal of the cloth pressing roller, reduces the difficulty of installing and removing the cloth pressing roller, and improves the speed of removing the cloth pressing roller, thus minimizing the difficulty of removing the cloth pressing roller to the greatest extent.

[0017] (2). For the needle punching machine with a press roller adjusting mechanism, when the two rotating wheels move to the topmost position, they will slide along the inclined surfaces of the two fixed bumps, causing the two connecting rods to move relative to each other, and then the cloth pressing roller can be removed, which facilitates the automatic removal of the cloth pressing roller, reduces the difficulty of removing the cloth pressing roller, and improves the speed of removing the cloth pressing roller.
