Description

Technical Field

[0001] This utility model relates to the field of aluminum foil bag processing, and in particular to a high-barrier four-layer aluminum foil bag composite device. Background Technology

[0002] Aluminum foil bags have a wide range of applications due to their excellent performance. They are mainly used for packaging food, pharmaceuticals, industrial products, and daily necessities, effectively extending shelf life. Four-layer aluminum foil bags are composed of four different plastic films, typically including layers of PET (polyester film), AL (aluminum foil), PA (nylon), and CPE (cast polyethylene). This composite structure gives four-layer aluminum foil bags excellent barrier properties, mechanical properties, and heat-sealing performance.

[0003] Four-layer aluminum foil bag laminating devices have broad application prospects in the packaging industry. For example, the laminating device for aluminum foil bag production disclosed in announcement number CN216832728U solves the problem of existing aluminum foil bag production devices having difficulty smoothly stuffing aluminum foil bag material between the extrusion rollers when laminating aluminum foil bags.

[0004] However, the device has some shortcomings. During the lamination process, the extrusion roller cannot repeatedly extrude the aluminum foil bag material, which can lead to uneven extrusion, resulting in air bubbles and wrinkles, thus affecting the appearance and barrier properties of the aluminum foil bag. In addition, there is no heating element to assist in the lamination process, which greatly reduces the lamination efficiency of the aluminum foil bag material. Utility Model Content

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] According to one embodiment of the present invention, in conjunction with Figure 1 - Figure 5 As shown. A high-barrier four-layer aluminum foil bag laminating device includes: a base plate 1, a guide mechanism 2 fixedly mounted at the front of the top of the base plate 1, a pressure roller 7 mounted behind the guide mechanism 2, two fixed protrusions 6 rotatably connected to both ends of the pressure roller 7, the two fixed protrusions 6 being fixedly connected to the top of the base plate 1, a laminating center 3 mounted behind the pressure roller 7, the laminating center 3 being fixedly connected to the top of the base plate 1, a cooling device 4 mounted behind the laminating center 3, the cooling device 4 being fixedly connected to the top of the base plate 1, and a winding mechanism 5 fixedly mounted at the rear of the top of the base plate 1. The pressure roller 7 and the two fixed protrusions 6 are divided into two groups, one group located in front of the laminating center 3 and the other group located behind the cooling device 4. By setting the fixed protrusions 6 and the pressure roller 7, the aluminum foil bag material to be laminated is guided from the guide mechanism 2, passes under the pressure roller 7 and is stretched. The pressure rollers 7 on both sides work together to make the aluminum foil bag material, the heating element 312 in the laminating center 3 and the bottom of the inner wall of the second shell 401 are on the same horizontal plane, which facilitates the positioning of the aluminum foil bag material and allows it to be laminated and cooled smoothly.

[0025] In this embodiment, the composite center 3 includes a tabletop 301, a heating element 312 fixedly mounted on the top of the base plate 1, and first housings 304 fixedly connected to both sides of the tabletop 301. The first housings 304 are fixedly connected to the top of the base plate 1. Two sliding grooves 303 are provided on both sides of the first housings 304. Sliding frames 310 are slidably connected to the inner walls of the two sliding grooves 303. Pressing rollers 309 are rotatably connected to both sides of the inner walls of the sliding frames 310. Several glue outlets 302 are provided on the top of the inner walls of the sliding frames 310, and the glue outlets 302 are located directly above the pressing rollers 309. A guide fluid 313 is fixedly provided on the top of the sliding frame 310. A glue outlet 308 is fixedly provided on the top of the guide fluid 313. A conduit 305 is sleeved on the surface of the glue outlet 308. A pump body 306 is connected to the top of the conduit 305. The bottom end of the pump body 306 is fixedly connected to the top of the first housing 304. A glue injection port 307 is opened on one side of the pump body 306. Two cylinders 311 are fixedly connected to both ends of the sliding frame 310. The interior of the sliding frame 310 is connected to the pressing roller 309 and several glue outlets 302. The two cylinders 311 are fixed on both sides of the second housing 401.

[0026] Using the above method, the coating is injected into the pump body 306 through the injection port 307, and then pumped into the guide fluid 313 through the conduit 305 from the outlet 308. The coating then flows from several outlets 302 to the surface of the pressing roller 309. The cylinder 311 is activated, and the extension and retraction ends of the two cylinders 311 stretch and drive the sliding frame 310 to slide on the inner wall of the groove 303, so that the pressing roller 309 repeatedly rolls and squeezes on the surface of the aluminum foil bag material, which facilitates the uniform application of the coating on the surface of the pressing roller 309 onto the aluminum foil bag material for lamination.

[0027] In this embodiment, the guide mechanism 2 includes two columns 201. An upper guide roller 202 and a lower guide roller 208 are rotatably connected between the two columns 201. The upper guide roller 202 is located above the lower guide roller 208. One end of the upper guide roller 202 passes through the interior of the column 201 and is fitted with an upper gear 203. The lower end of the upper gear 203 is meshed with a lower gear 207. The lower gear 207 is fitted onto one end of the column 201 and fixedly connected to a first support plate 205. The top end of the first support plate 205 is fixedly connected to a first motor base 206. The top end of the first motor base 206 is fixedly provided with a first motor 204. The lower gear 207 is fitted onto the drive end of the first motor 204.

[0028] Through the above scheme, the four layers of aluminum foil bag material are passed between the upper guide roller 202 and the lower guide roller 208 respectively. The first motor 204 is started, causing the lower gear 207 to rotate, which drives the upper gear 203 to rotate. The rotation of the lower gear 207 and the upper gear 203 drives the rotation of the upper guide roller 202 and the lower guide roller 208, transporting the four layers of aluminum foil bag material. Then, it passes under the surface of the pressure roller 7 and is stretched. With the cooperation of the pressure rollers 7 on both sides, the aluminum foil bag material is brought to the same horizontal plane as the heating element 312 in the composite center 3 and the bottom of the inner wall of the second shell 401, which facilitates the smooth progress of the composite process.

[0029] In this utility model, the cooling device 4 includes a second housing 401, a positioning frame 403 is fixedly connected to the top of the second housing 401, a second motor 404 is fixedly connected to the top of the inner wall of the positioning frame 403, a fan blade 405 is sleeved on the driving end of the second motor 404, and a ventilation port 402 is opened at the top of the second housing 401, which is located directly below the fan blade 405.

[0030] Through the above scheme, the aluminum foil bag material passes through the bottom of the inner wall of the second housing 401, and the fan blade 405 is driven to rotate by the second motor 404 at the top, blowing air from the vent 402 to the surface of the aluminum foil bag material, which can effectively cool down the aluminum foil bag that has been laminated.

[0031] In this utility model, the winding mechanism 5 includes a third motor 503, a second base 504 fixedly connected to the bottom end of the third motor 503, a second support plate 505 fixedly connected to the bottom end of the second base 504, a winding frame 501 connected through and rotatably to the driving end of the third motor 503, a winding roller 502 fixedly connected to the driving end of the third motor 503, and a winding roller 502 with one end away from the third motor 503 penetrating the surface of the winding frame 501 and rotatably connected to the inside of the winding frame 501.

[0032] Using the above method, the aluminum foil bag material is wrapped around the surface of the take-up roller 502, and the third motor 503 is started. The drive end of the third motor 503 drives the take-up roller 502 to rotate for the final take-up operation.

[0033] Working principle: In use, four layers of aluminum foil bag material are passed between the upper guide roller 202 and the lower guide roller 208 respectively. The first motor 204 is started, causing the lower gear 207 to rotate, which in turn drives the upper gear 203 to rotate. The rotation of the lower gear 207 and the upper gear 203 drives the rotation of the upper guide roller 202 and the lower guide roller 208, transporting the four layers of aluminum foil bag material. Then, it passes under the surface of the pressure roller 7 and is stretched. The pressure rollers 7 on both sides work together to make the aluminum foil bag material level with the heating element 312 in the composite center 3 and the bottom of the inner wall of the second shell 401. The coating is injected into the pump body 306 through the glue injection port 307, and then pumped into the guide fluid 313 from the glue outlet 308 through the conduit 305. The coating is then discharged from several glue outlets 302. The coating material is left on the surface of the pressing roller 309. The cylinder 311 is started, and the extension ends of the two cylinders 311 stretch and drive the sliding frame 310 to slide on the inner wall of the slide groove 303, so that the pressing roller 309 repeatedly rolls and squeezes on the surface of the aluminum foil bag material, so that the coating on the surface of the pressing roller 309 is evenly coated on the aluminum foil bag material for lamination. After lamination, the aluminum foil bag material passes through the bottom of the inner wall of the second housing 401. The second motor 404 at the top drives the fan blade 405 to rotate, blowing air from the vent 402 to the surface of the aluminum foil bag material for cooling. Then the aluminum foil bag material is wrapped on the surface of the take-up roller 502. The third motor 503 is started, and the drive end of the third motor 503 drives the take-up roller 502 to rotate for the final winding work.
