Description

Technical Field

[0001] This utility model belongs to the field of woven bag processing technology, specifically relating to a plastic woven bag laminating machine. Background Technology

[0002] The lamination process for plastic woven bags is a post-processing step performed after the bags are woven into fabric. The laminated plastic woven bags have a smoother and brighter surface, which not only improves the gloss of the woven bags but also protects the plastic film from moisture, water, dirt, and abrasion.

[0003] Existing Chinese patent CN217454938U discloses a plastic woven bag laminating machine, including a base plate and a support plate. The support plate is installed on the top of the base plate. It also includes an A-shaft, a B-shaft, a rotating shaft, a pressure roller, an A-ring, a B-ring, an A-motor, a drive mechanism, and a heating mechanism. Both A-shafts are rotatably mounted on the front end of the support plate via bearings. The A-motor is installed at the rear end of the support plate, and the B-shaft is located at the output end of the A-motor. The front end of shaft B extends to the front side of the support plate. External threads are provided on the outer walls of shaft B and the two sets of shafts A. A B-retaining ring is threaded onto shaft B, and A-retaining rings are threaded onto the two sets of shafts A. The two sets of shafts pass through the support plate and are rotatably connected to it via bearings. Pressure rollers are installed on each set of shafts, both located on the front side of the support plate. A drive mechanism is installed at the rear end of the support plate for synchronous, opposite rotation of the two sets of shafts. A heating mechanism is installed at the front end of the support plate. A woven bag roll is placed onto shaft B, and the B-retaining ring is threaded onto shaft B to secure the roll. The two sets of shafts A... Separately, the film rolls are fixed by connecting two sets of A-rings to the corresponding A-shafts. The starting end of the woven bag roll and the starting ends of the two sets of film rolls are passed sequentially between the two sets of pressure rollers, and then through the heating mechanism. The A motor is started to unwind the woven bag roll by the B-shaft. The drive mechanism is started, so that the two sets of rotating shafts drive the two sets of pressure rollers to rotate synchronously in opposite directions. The two sets of pressure rollers work together to press the film on the left and right sides of the woven bag, so that no air bubbles are left between the woven bag and the film. Then, the woven bag and the film on both sides enter the heating mechanism for lamination, which improves the lamination efficiency of the woven bag and saves time and resources.

[0004] Regarding the aforementioned related technologies, the inventors have discovered at least the following problems: because the woven bags and film surfaces exposed to the outside world for a long time are prone to dust accumulation, during the lamination process, the dust is easily squeezed between the woven bags and film, which affects the lamination effect. Utility Model Content

[0005] The purpose of this invention is to provide a plastic woven bag laminating machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic woven bag laminating machine, comprising a support base, a laminating mechanism, and a dust removal mechanism. The laminating mechanism includes a laminating box fixedly installed on one side of the support base. Two heated laminating rollers are rotatably installed inside the laminating box. A woven bag roll is rotatably installed on the support base above the laminating box. Film rolls are rotatably installed on both sides of the woven bag roll on the support base. Three feed ports are provided on the top of the laminating box.

[0007] The dust removal mechanism includes a dust collection box fixedly installed on the outer wall of the film-coating box. A dust extraction fan is fixedly connected to the top of the dust collection box. A connecting pipe is fixedly connected to the outlet end of the dust extraction fan. Both ends of the connecting pipe are fixedly connected to suction pipes. The suction pipes are fixedly inserted into the film-coating box. Dust suction hoods are fixedly connected to both sides of the suction pipes.

[0008] In a preferred embodiment, the support base is rotatably mounted with a first guide roller on one side of each feed inlet.

[0009] In a preferred embodiment, a second guide roller is rotatably mounted on one side of each feed inlet inside the coating box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This plastic woven bag laminating machine, through the setting of a dust removal mechanism, can start the dust extraction fan after the woven bags and films enter the laminating box, so that the dust suction hood is directed at the surface of the woven bags and films to suck up the dust into the dust suction hood, and then suck it into the dust collection box through the dust suction pipe and connecting pipe in sequence. After the dust is filtered by the filter screen, the dust falls into the drawer, thereby removing the dust attached to the surface of the woven bags and films and avoiding the laminating effect being affected by dust.

[0015] This plastic woven bag laminating machine, through the setting of the first and second guide rollers, can guide the woven bags and films when they are conveyed into the laminating box, so that the woven bags and films are almost close to the dust collection hood after entering the laminating box, thus improving the dust collection effect.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-3 This utility model provides a plastic woven bag laminating machine, including a support base 1, a laminating mechanism 2, and a dust removal mechanism 3. The laminating mechanism 2 includes a laminating box 21 fixedly installed on one side of the support base 1. Two heated laminating rollers 22 are rotatably installed inside the laminating box 21. A woven bag roll 23 is rotatably installed on the support base 1 above the laminating box 21. Film rolls 24 are rotatably installed on both sides of the support base 1 on the woven bag roll 23. Three feed ports 25 are opened on the top of the laminating box 21, and a discharge port 28 is opened on the bottom of the laminating box 21. With the setting of the laminating mechanism 2, during laminating, the woven bags on the woven bag roll 23 can be fed into the laminating box 21 from the middle feed port 25, and the films on the two film rolls 24 can be fed into the laminating box 21 from the feed ports 25 on both sides, so that the woven bags and films pass between the two heated laminating rollers 22 to laminate the woven bags.

[0023] Specifically, the dust removal mechanism 3 includes a dust collection box 31 fixedly installed on the outer wall of the film-coating box 21. A dust extraction fan 32 is fixedly connected to the top of the dust collection box 31. A connecting pipe 33 is fixedly connected to the outlet end of the dust extraction fan 32. Both ends of the connecting pipe 33 are fixedly connected to suction pipes 34, which are fixedly inserted into the film-coating box 21. Dust suction hoods 35 are fixedly connected to both sides of the suction pipes 34. A drawer 36 is slidably inserted into one side of the dust collection box 31. An exhaust hole is opened on the top of one side of the dust collection box 31, and a fixed exhaust hole is installed inside the exhaust hole. With the filter 37 connected, the dust removal mechanism 3 allows the dust extraction fan 32 to be activated after the woven bag and film enter the laminating box 21. This causes the dust extraction hood 35 to suck up the dust from the surface of the woven bag and film, drawing the dust into the dust extraction hood 35. The dust then passes through the dust extraction pipe 34 and the connecting pipe 33 into the dust collection box 31. After being filtered by the filter 37, the dust falls into the drawer 36, thus removing the dust adhering to the surface of the woven bag and film and preventing the laminating effect from being affected by the dust.

[0024] The support base 1 is rotatably mounted with a first guide roller 26 on one side of each feed port 25, and the laminating box 21 is rotatably mounted with a second guide roller 27 on one side of each feed port 25. The first guide roller 26 and the second guide roller 27 guide the woven bags and films when they are fed into the laminating box 21, so that the woven bags and films are almost close to the dust collection hood 35 after entering the laminating box 21, thus improving the dust collection effect.

[0025] The working principle and usage process of this utility model are as follows: First, during the lamination process, the woven bags on the woven bag roll 23 are fed into the lamination box 21 through the middle feed port 25, and the films on the two film rolls 24 are fed into the lamination box 21 through the feed ports 25 on both sides, so that the woven bags and films pass between the two heated lamination rollers 22 to laminate the woven bags. After the woven bags and films enter the lamination box 21, the dust extraction fan 32 can be started so that the dust extraction hood 35 can be used to extract dust from the surface of the woven bags and films. The dust on the surface of the woven bags and films is sucked into the dust extraction hood 35, and then sucked into the dust collection box 31 through the dust extraction pipe 34 and the connecting pipe 33. After the dust is filtered by the filter screen 37, the dust falls into the drawer 36, thereby removing the dust attached to the surface of the woven bags and films and avoiding the lamination effect being affected by dust.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
