Description

Technical Field

[0001] The utility model belongs to the technical field of packaging composite film production, and particularly relates to a lining paper and aluminum foil composite device. Background Art

[0002] Due to its excellent properties, aluminum foil is widely used in food, beverages, cigarettes, medicines, photographic plates, household daily necessities, etc., usually as their packaging materials; electrolytic capacitor materials; insulation materials for buildings, vehicles, ships, houses, etc.; it can also be used as decorative gold and silver threads, wallpaper, and decorative trademarks for various stationery prints and light industrial products. In order to improve the properties of the packaging film, other materials can also be compounded with aluminum foil to produce corresponding composite films to improve the properties of the packaging paper.

[0003] The existing production process for composite films typically involves applying glue to a layer of inner liner paper, followed by a press roller to bond the inner liner paper and aluminum foil. This leads to difficulties in controlling the amount of glue applied, which can easily lead to glue overflow at the edges during lamination. This can cause glue to adhere to equipment that subsequently comes into contact with the laminated film, making it difficult to clean.

[0004] Document CN221392609U discloses an embossed liner paper aluminum foil lamination device, comprising two sets of raw material rollers and a pressure roller. A glue box is located between the pressure roller and the raw material rollers. A glue roller rotates within the glue box, and a glue-applying roller is attached to the surface of the glue roller. A glue scraping mechanism is fixed to the inner wall of the glue box. Compared to traditional equipment, this device features a glue scraping head that can scrape glue off the edge of the liner paper to prevent glue from overflowing.

[0005] However, the device still has the following problems: when the liner paper is conveyed at a certain tilt angle, glue will accumulate on the glued surface under the action of gravity. In this case, even if the glue on the edge has been scraped off, the edge overflow will reappear due to the excessive amount of local glue during lamination. Utility Model Content

It has the advantages of simple structure and strong practicality.

[0033] Example 1

[0034] This embodiment provides a lining paper aluminum foil composite device, including a support frame 11, two raw material rollers 12 arranged on the support frame 11, an upper pressure roller 13 and a lower pressure roller 14 rotatably arranged on the support frame 11 and distributed up and down in the vertical direction, the support frame 11 is also provided with a gluing structure 2 located on the conveying path of the raw material roller 12 and the upper pressure roller 13 and located at the lower end of the lining paper a, and a gluing structure 3 arranged on the end of the gluing structure 2 close to the upper pressure roller 13; the gluing structure 3 includes at least one gluing cylinder 31 with a length greater than or equal to the width of the lining paper a and used for sliding connection with the lower surface of the lining paper a.

[0035] In this embodiment, the two raw material rollers 12 are distributed up and down in the vertical direction, and the upper raw material roller 12 and the upper pressure roller 13 are used to convey the lining paper a, and the lower raw material roller and the lower pressure roller 14 are used to convey the aluminum foil b. The lining paper a is tilted downward, and the lower surface of the lining paper a is glued by the gluing structure 2 at the front end of the upper pressure roller 13, and the glue that may be gathered due to gravity is coated for the second time by the gluing cylinder 31 to ensure that the amount of glue coated on the lower surface of the lining paper a is appropriate and evenly distributed, thereby avoiding glue overflow when the upper pressure roller 13 and the lower pressure roller 14 press the lining paper a and the aluminum foil b.

[0036] It is worth noting that the two raw material rollers 12 and the upper pressure roller 13 are fixed in position on the support frame 11, and the lower pressure roller 14 can be adjusted on the support frame 11 in the vertical direction, so as to control the pressing force between the lower pressure roller 14 and the upper pressure roller 13, and thus control the pressing effect. The structure for adjusting the lower pressure roller 14 can adopt technologies well known to those skilled in the art, such as direct drive by a motor, a cylinder, etc. The present device adopts the method of "the upper pressure roller 13 is fixed in position and the lower pressure roller 14 is adjustable" in order to ensure that the upper pressure roller 13 is fixed in position on the lining paper a on the basis of being able to adjust the pressing force, thereby ensuring that the conveying angle of the lining paper a is stable, and further ensuring that the gluing structure 3 can stably perform a secondary coating process on the lower surface of the lining paper a.

[0037] In this embodiment, the gluing structure 2 includes a glue box 21, a gluing roller 22 rotatably disposed within the glue box 21, a gluing roller 23 rotatably disposed on a support frame 11 and connected at its upper and lower ends to the lower surface of the liner paper a and the upper surface of the gluing roller 22, respectively; a feed pipe 24 and a discharge pipe 25 disposed at the lower end of the glue box 21; and a glue storage barrel 26 disposed on the support frame 11 and connected to the feed pipe 24 and the discharge pipe 25. The glue box 21 has an open top and a length that is greater than or equal to the length of the gluing roller 23. The upper end of the gluing roller 22 protrudes from the top end of the glue box 21 to ensure gluing of the gluing roller 23. The gluing roller 22 and the gluing roller 23 have the same length and can have the same or different diameters, depending on the required gluing amount for the liner paper. The glue storage barrel 26 is connected to the glue box 21 via the feed pipe 24 and the discharge pipe 25 to store and recycle the glue liquid.

[0038] The lining paper and aluminum foil composite device provided in this embodiment has the advantages over the existing device in that a gluing structure for secondary coating of glue on the surface of the lining paper is arranged at the rear end of the gluing structure and the front end of the lamination roller to control the amount of glue on the surface of the lining paper, so that the glue coating on the surface of the lining paper is uniform and stable, and the glue overflow phenomenon is reduced. It has the advantages of simple structure and strong practicality.

[0039] Example 2

[0040] This embodiment optimizes the structure based on the embodiment 1, specifically as follows:

[0041] The glue coating structure 3 also includes two mounting plates 32 located on both sides of the glue coating cylinder 31 and rotatably connected to the glue coating cylinder 31, two rotating plates 33 respectively arranged on the ends of the two mounting plates 32, two fixed side plates 34 arranged on the side ends of the glue coating structure 2 and rotatably connected to the two rotating plates 33, and a driving member 35 for driving the rotating plates 33 to rotate to adjust the glue coating position of the glue coating cylinder 31.

[0042] In this embodiment, the driving member 35 includes a driving shaft 351 rotatably arranged between the two fixed side plates 34, a first wheel body 352 arranged on the driving shaft 351, a motor 353 arranged on the side end of the upper glue structure 2, a second wheel body 354 arranged on the output end of the motor 353, and a transmission belt 355 for connecting the first wheel body 352 and the second wheel body 354; the lower ends of the two rotating plates 33 are respectively fixedly connected to the two ends of the driving shaft 351.

[0043] It is worth noting that the drive member 35 drives the glue coating cylinder 31 to rotate, thereby enabling the glue coating cylinder 31 to perform both coating and scraping functions. During coating, the drive member 35 drives the glue coating cylinder 31 to contact the lower surface of the liner paper a, promoting secondary coating of the glue liquid; during scraping, the drive member 35 drives the glue coating cylinder 31 to contact the glue roller 23, thereby scraping the glue on the surface of the glue roller 23.

[0044] In this embodiment, the glue coating cylinder 31 includes a fixed shaft 311 whose two ends are respectively connected to the two mounting plates 32, a main body 312 rotatably arranged on the fixed shaft 311, an arc-shaped protrusion 313 arranged on one side of the main body 312, a scraping protrusion 314 arranged on the side of the main body 312 away from the arc-shaped protrusion 313, and a locking member 315 for controlling the rotation angle of the main body 312.

[0045] Among them, the lengths of the main body 312, the arc-shaped protrusion 313 and the scraping protrusion 314 must all be greater than or equal to the width of the lining paper a; the cross-section of the arc-shaped protrusion 313 is preferably a superior arc, so that the area in which it fits with the lower surface of the lining paper a is larger, which promotes the uniform distribution of the glue and reduces the wear on the lining paper a; the cross-section of the scraping protrusion 314 is preferably an acute angle, and the tip of the angle is arc-shaped to avoid scratching the lining paper. When the scraping protrusion 314 is rotated and fits with the lower surface of the lining paper a, its vertical height is greater than the vertical height of the arc-shaped protrusion 313 in contact with the lower surface of the lining paper. Therefore, the scraping protrusion 314 is used to adapt to a higher coating position, so that the glue coating cylinder 31 has a certain height adjustment range, thereby improving its practicality. Furthermore, when scraping the glue, it is preferred to use the scraping protrusion 314 to fit the glue roller 23. Since it has a relatively sharp protrusion, it is easy to remove the glue on the surface of the glue roller 23, thereby ensuring the stability of the glue coating.

[0046] As a further preferred embodiment of this embodiment, the locking member 315 includes a locking groove 315a provided on the side end of the arc-shaped protrusion 313, an arc-shaped through-hole 315b provided on the mounting plate 32 and matching the rotation trajectory of the locking groove 315a, a locking screw 315c passing through the arc-shaped through-hole 315b and connected to the locking groove 315a, and a limiting nut 315d provided on the locking screw 315c. The arc-shaped through-hole 315b defines the adjustment range of the rotation of the glue coating cylinder 31, and the locking groove 315a is provided with an internal thread. The glue coating cylinder 31 is fixed by the threaded connection between the locking screw 315c and the locking groove 315a, and further by the limiting nut 315d abutting against the mounting plate 32.

[0047] As a further preferred embodiment of this embodiment, the locking member 315 further includes a placement plate 315e disposed on a side end of the mounting plate 32, and a hole 315f disposed on the placement plate 315e for passing the locking screw 315c. The placement plate 315e is for passing the locking screw 315c, and the hole 315f has a diameter larger than that of the locking screw 315c and smaller than that of the limiting nut 315d. The limiting nut 315d secures the locking screw 315c to the placement plate 315e, thereby storing the limiting screw 315c when it is in a waiting position.

[0048] As a further preferred embodiment of this embodiment, the gluing structure 3 further includes a guide plate 36 disposed between the two mounting plates 32 and located on the side of the gluing cylinder 31 away from the inner liner paper a. A folding plate 361 is provided on the end of the guide plate 36 proximal to the gluing structure 2. The guide plate 36 is used to guide the glue dropped by the gluing cylinder 31 during operation into the glue tank 21, thereby facilitating the recovery of the glue and preventing the glue from contaminating other equipment.

[0049] As a further preferred embodiment of the present invention, the gluing structure 3 further includes a lever 37 provided on the side wall of the mounting plate 32 close to the gluing cylinder 31 and located on the movement trajectory of the scraping protrusion 314. The lever 37 is used to play a role when the arc-shaped protrusion 313 is in contact with the lower surface of the liner paper a for secondary coating. At this time, the locking member 315 is fixed on the placement plate 315e, and the gluing cylinder 31 can rotate. When the arc-shaped protrusion 313 is subjected to the force of the liner paper a, it has a tendency to rotate away from the movement direction of the liner paper a, which easily causes the arc-shaped protrusion 313 to separate from the liner paper a, which affects the stability of the coating. Therefore, the lever 37 is provided to prevent the rotation of the gluing cylinder 31 and ensure that the arc-shaped protrusion 313 is in contact with the lower surface of the liner paper a.

[0050] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
