Description

Technical Field

[0001] The utility model relates to a bonding machine, in particular to a non-woven fabric thermal bonding machine, belonging to the technical field of non-woven fabric processing. Background Art

[0002] As is well known, non-woven fabric is composed of oriented or random fibers and is called fabric because of its fabric appearance and certain properties. It is mostly made of polypropylene pellets as raw materials and is produced by a continuous one-step method of high-temperature melting, spinning, web laying, and hot pressing and coiling. During the bonding process of non-woven fabric, a thermal bonding machine is needed. As the prior art of the thermal bonding machine, a Chinese published patent (Publication No.: CN220720566U) discloses a non-woven fabric thermal bonding machine, which includes a workbench, a concave support plate, and a heating device. The upper end of the workbench is sequentially installed with a concave support plate and a heating device through bolts. Convex grooves are symmetrically opened on the left and right sides of the concave support plate. Concave limit plates are symmetrically arranged up and down inside the concave support plate. One of the lower concave limit plates is fixedly connected to the upper end of the workbench. A lifting adjustment mechanism is installed at the upper end of one of the upper concave limit plates. Convex sliders are symmetrically welded on the left and right sides of one of the upper concave limit plates. Connecting seats are symmetrically installed on the left and right sides inside both concave limit plates. The beneficial effect of the utility model is that when thermally bonding non-woven fabric, first preheat the non-woven fabric through the heating device, and then make the non-woven fabric pass through between two pressing rollers, and the non-woven fabric is extruded and bonded by the cooperation of the two pressing rollers.

[0003] However, when the existing non-woven fabric thermal bonding machine is in use, since there is no dust suction treatment step before the non-woven fabric enters the heating device, black spots and other problems will occur after the non-woven fabric with dust is thermally bonded, which is not conducive to maintaining good processing quality. Therefore, a non-woven fabric thermal bonding machine is proposed. Summary of the Utility Model

[0004] In view of this, the utility model provides a non-woven fabric thermal bonding machine to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial option.

[0005] The technical solution of the utility model is realized as follows: A non-woven fabric thermal bonding machine includes a thermal bonding machine body and a dust suction mechanism;

The bottom of the hollow shell is uniformly communicated with a plurality of dust suction pipes distributed at equal intervals. One side of the dust collection box is communicated with a hose. One end of the hose penetrates through the movable plate and is communicated with the hollow shell.

[0008] Further preferably, a conveyor belt is fixedly installed on the top of the workbench, and the conveyor belt is arranged on the side of the heating device away from the bracket.

[0011] Further preferably, a box door is hinged on one side of the dust collection box.

[0012] Further preferably, a dust collection filter screen is fixedly embedded on the top of the dust collection box and close to one side of the air inlet hopper through screws.

[0013] Further preferably, the bottom end of the lead screw is rotatably connected with a support block through a bearing, and one side of the support block is fixedly connected with the workbench.
