Description

Technical Field

[0001] The utility model relates to the field of woven bag production, in particular to a film pulling mechanism for woven bag production. Background Technique

[0002] Woven bags are widely used for packaging industrial and agricultural products in transportation. In the packaging of agricultural products, woven bags have been widely used for packaging aquatic products, poultry feed, covering materials for farms, sunshade, windproof, and hail-proof shed materials for crop planting. Common products include feed woven bags, chemical woven bags, putty powder woven bags, urea woven bags, vegetable mesh bags, etc. When producing woven bags, a film pulling mechanism is required to stretch the film into the required thickness.

[0003] After retrieval, the Chinese patent publication number is CN220500119U, which discloses a film pulling mechanism for woven bag production. By controlling the switch group to start the first motor, the molten material is introduced into the interior of the hopper. The output shaft of the first motor drives the uppermost extrusion roller to rotate. The uppermost extrusion roller drives the adjacent lower extrusion roller to rotate through multiple sprockets and chains in mesh. The two horizontally corresponding extrusion rollers extrude the material. Since both connecting plates are inclined, the distance between the two horizontally corresponding extrusion rollers decreases successively from top to bottom, and the extrusion thickness of the woven bag film becomes smaller and smaller. The extruded woven bag film is guided by the guide roller and wound around the outer surface of the winding roller. The winding roller further stretches the woven bag film. The static electricity on the surface of the woven bag film is introduced into the water inside the water tank through the conductive metal ring and the wire, avoiding the static electricity from adsorbing dust in the surrounding environment. This film pulling mechanism for woven bag production facilitates the rapid forming of the woven bag film, improves the film pulling efficiency, automatically eliminates the static electricity on the surface of the woven bag film, and has strong practicability.

[0004] In the prior art, after the film of the woven bag is pulled, the woven bag is usually cooled by water, but a large amount of water droplets will adhere to the surface of the woven bag after water cooling, which is not convenient for subsequent processing. Content of the Utility Model

[0025] The present utility model will be further described below with reference to the accompanying drawings:

[0026] As Figures 1-6 shown, a film pulling mechanism for the production of woven bags includes a base 1. A support frame 2 is bolted to the top of the base 1. The support frame 2 is in an inverted U shape. A hopper 3 is bolted to the top of the support frame 2. A film pulling mechanism is arranged below the hopper 3. The film pulling mechanism includes a limiting shell 401 bolted to the inner top wall of the support frame 2 and communicating with the hopper 3. A plurality of upper and lower corresponding first extrusion rollers 402 and second extrusion rollers 403 are rotatably connected between the inner walls of the limiting shell 401. The gap between the first extrusion roller 402 and the second extrusion roller 403 decreases sequentially from top to bottom until the woven bag is stretched to the required thickness. A rotating motor �04 is bolted to the rear side of the limiting shell 401. The output end of the rotating motor 404 is connected to one of the first extrusion rollers 402 or the second extrusion roller 403 through a coupling. Synchronous belts 405 are connected between two adjacent first extrusion rollers 402 and between two adjacent second extrusion rollers 403. The ends of one set of first extrusion rollers 402 and second extrusion rollers 403 extend out of the limiting shell 401 and are fixedly connected with first gears 406. The two first gears 406 mesh with each other.

[0027] A water tank 5 is fixedly connected to the top of the base 1. A guide roller 501 is fixedly connected between the inner walls of the water tank 5. Cold water is stored in the water tank 5, and the water in the water tank 5 is replaced regularly.

[0028] An air drying mechanism is arranged on one side of the water tank 5. The air drying mechanism includes two vertical plates 701 bolted to the top of the base 1. The two vertical plates 701 are arranged front and rear. Two air ducts 702 are fixedly connected between the two vertical plates 701. The two air ducts 702 are arranged up and down. A plurality of nozzles 703 are fixedly connected to the air ducts 702. The air drying mechanism further includes an air supply component.

[0029] The air supply component includes a fan 704 bolted to the rear side of the rear vertical plate 701. The air outlet of the fan 704 is communicated with one of the air ducts 702. A ventilation cavity for communicating the two air ducts 702 is opened in the front vertical plate 701. When the fan 704 is started, the air blown out by the fan 704 enters the air duct 702 and is then blown out towards the woven bag by the nozzles 703.

[0030] On the other side of the air-drying mechanism, there is a winding mechanism. The winding mechanism includes a servo motor 801 bolted to the rear side of the rear vertical plate 701. The output end of the servo motor 801 is connected to a winding roller 802 through a coupling. The winding roller 802 is rotatably connected between the two vertical plates 701. When the servo motor 801 is started, the servo motor 801 drives the winding roller 802 to rotate, and while winding the woven bag, the woven bag is further stretched.

[0031] An absorbing mechanism is arranged in the water tank 5. The absorbing mechanism includes two rollers 601 rotatably connected between the inner walls of the water tank 5. An absorbing layer 602 is pasted on the outer part of the roller 601. Two scraping plates 603 are fixedly connected between the inner walls of the water tank 5. The scraping plates 603 are in contact with the absorbing layer 602, and the water absorbed in the absorbing layer 602 is squeezed out by the scraping plates 603 to ensure the water absorption effect of the absorbing layer 602. The absorbing mechanism further includes a power assembly for driving the roller 601 to rotate.

[0032] The power assembly includes a stepping motor 604. The stepping motor 604 is bolted to the rear side of the water tank 5. The output end of the stepping motor 604 is connected to one of the rollers 601 through a coupling. The front ends of the two rollers 601 extend out of the water tank 5 and are fixedly connected with a second gear 605. The two second gears 605 mesh with each other, and the transmission between the two rollers 601 is realized through the second gear 605.

[0033] Working principle: During use, the molten material is introduced into the hopper 3. The rotating motor 404 is started, and the rotating motor 404 drives one of the first extrusion rollers 402 or the second extrusion roller 403 to rotate. The other first extrusion rollers 402 and second extrusion rollers 403 are driven through the synchronous belt 405 and the first gear 406. The material is extruded by the two horizontally corresponding first extrusion rollers 402 and second extrusion rollers 403. The extruded woven bag film passes through between the two rollers 601 and between the two air ducts 702 in sequence after being guided by the guide roller 501, and finally winds around the outer surface of the winding roller 802. The water in the water tank 5 cools the just-extruded woven bag. The stepping motor 604 is started, and the stepping motor 604 drives the roller 601 to rotate. The water on the surface of the woven bag is absorbed by the absorbing layer 602 on the roller 601, which is convenient for subsequent processing. The water absorbed in the absorbing layer 602 is timely squeezed out by the scraping plate 603 to ensure the water absorption effect of the absorbing layer 602. The water squeezed out by the scraping plate 603 falls into the water tank 5 for recycling. The blower 704 is started, and the air blown out through the nozzle 703 further dries the surface of the woven bag.
