Description

Technical Field

[0001] The invention relates to the technical field of automatic laminating machines, and in particular to an automatic laminating machine for processing paper tubes. Background Art

[0002] The automatic laminating machine is a highly efficient and precise post-printing processing equipment, which is mainly used to cover the surface of printed materials with transparent film. The automatic laminating machine can laminate a variety of cylindrical parts, such as health care product paper tubes, tea paper cans, cosmetic cylinders, etc. These paper tubes can be laminated to enhance their moisture resistance, anti-fouling and durability, while improving the product's aesthetics and market competitiveness.

[0003] However, the existing automatic laminating machines for paper tube processing lack a structure for tensioning the film during the laminating process. During the laminating process, the film may become loose or wrinkled due to insufficient tension, and it does not have the function of assisting the lamination, resulting in a poor laminating effect. For this reason, we propose an automatic laminating machine for paper tube processing. Summary of the invention

[0004] In response to the problems in the prior art, the present invention provides an automatic laminating machine for paper tube processing. The new automatic laminating machine for paper tube processing has a structure for tensioning the film during the laminating process to prevent the film from becoming loose or wrinkled during the laminating process, and has the function of assisting the lamination, thereby effectively improving the laminating effect.

[0005] The technical solution adopted by the present invention to solve the technical problem is an automatic laminating machine for paper tube processing, comprising a bottom plate, a paper tube and a film roll are respectively arranged at two ends of the top of the bottom plate, a first synchronous motor and a second synchronous motor are respectively installed on the top of the bottom plate and on one side of the paper tube and the film roll, a first tensioning roller is arranged on the side of the top of the bottom plate close to the film roll, and a second tensioning roller is arranged on the side of the top of the bottom plate close to the paper tube;

[0006] A film is wrapped around the outside of the film roll, one end of the film passes through the top of the No. 1 tensioning roller and the bottom of the No. 2 tensioning roller in sequence and is connected to the outside of the paper tube. An auxiliary laminating roller is installed on the top of the bottom plate and on the outside of the paper tube through a mounting frame, and both ends of the auxiliary laminating roller are connected to the mounting frame through bearings.

[0007] By adopting the above technical solution, the No. 1 synchronous motor can drive the paper drum and the film roll to rotate respectively. When the film is stretched by the paper drum and the film roll between them, the film generates tension. Through the pulling force and friction force, the No. 1 tensioning roller and the No. 2 tensioning roller can rotate. Since the film has tension, it can avoid the film from being loosened or wrinkled during the laminating process.

[0008] The staff installs the auxiliary laminating roller on the outside of the paper tube so that the outer edge of the auxiliary laminating roller fits the outer edge of the paper tube, so that the film can be closely attached to the paper tube, making the laminating effect better;

[0009] The bracket can raise the height of the No. 1 tensioning roller, so that a height difference is formed between the No. 1 tensioning roller and the No. 2 tensioning roller, and then a better tensioning effect is achieved due to the angle change caused by the height difference.

[0010] Specifically, two ends of the paper tube, the first tensioning roller, the film roll and the second tensioning roller are respectively provided with a first bearing seat, a second bearing seat, a third bearing seat and a fourth bearing seat.

[0011] By adopting the above technical solution, the No. 1 bearing seat, the No. 2 bearing seat, the No. 3 bearing seat and the No. 4 bearing seat can respectively facilitate the smooth rotation of the paper tube, the No. 1 tensioning roller, the film roll and the No. 2 tensioning roller.

[0012] Specifically, the output end of the first synchronous motor is connected to the paper tube.

[0013] By adopting the above technical solution, the No. 1 synchronous motor can drive the paper tube to rotate.

[0014] Specifically, the output end of the second synchronous motor is connected to the film roll.

[0015] Specifically, the bottom of the No. 2 bearing seat is connected to the base plate through a bracket.

[0016] By adopting the above technical solution, the bracket can support the No. 1 tensioning roller and the No. 2 bearing seat, and can make the height of the No. 1 tensioning roller higher than the height of the No. 2 tensioning roller.

[0017] Specifically, bases are provided at both ends of the bottom of the base plate.

[0018] Specifically, the paper tube, the first tensioning roller, the film roll, the second tensioning roller and the auxiliary laminating roller are all provided with a central rod inside.

[0019] Beneficial effects of the present invention:

[0020] (1) In the automatic laminating machine for paper tube processing described in the present invention, a synchronous motor No. 1 can drive the paper tube and the film roll to rotate respectively. When the film is stretched between the paper tube and the film roll, tension is generated in the film. Through the pulling force and friction force, the tension roller No. 1 and the tension roller No. 2 can rotate. Since the film has tension, it can avoid the film from being loosened or wrinkled during the laminating process.

[0021] (2) In the automatic laminating machine for paper tube processing described in the present invention, a person installs an auxiliary laminating roller on the outside of the paper tube so that the outer edge of the auxiliary laminating roller fits with the outer edge of the paper tube, so that the film can be tightly attached to the paper tube, resulting in a better laminating effect.

[0022] (3) In the automatic laminating machine for paper tube processing described in the present invention, the bracket can raise the height of the No. 1 tensioning roller, so that a height difference is formed between the No. 1 tensioning roller and the No. 2 tensioning roller, and then due to the angle change caused by the height difference, a better tensioning effect is achieved.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0029] In order to improve the coating effect, Figure 1-3 As shown, an automatic laminating machine for paper tube processing according to the present invention comprises a bottom plate 1, a paper tube 4 and a film roll 6 are respectively arranged at two ends of the top of the bottom plate 1, a first synchronous motor 2 and a second synchronous motor 3 are respectively installed on the top of the bottom plate 1 and on one side of the paper tube 4 and the film roll 6, a first tensioning roller 5 is arranged on the side of the top of the bottom plate 1 close to the film roll 6, and a second tensioning roller 7 is arranged on the side of the top of the bottom plate 1 close to the paper tube 4;

[0030] A film 12 is wrapped around the outside of the film roll 6, and one end of the film 12 passes through the top of the No. 1 tensioning roller 5 and the bottom of the No. 2 tensioning roller 7 in sequence and is connected to the outside of the paper tube 4. An auxiliary laminating roller 16 is installed on the top of the bottom plate 1 and located on the outside of the paper tube 4 through a mounting frame 17, and both ends of the auxiliary laminating roller 16 are connected to the mounting frame 17 through bearings.

[0031] When in use, the first synchronous motor 2 can drive the paper drum 4 and the film roll 6 to rotate respectively. When the film 12 is stretched by the paper drum 4 and the film roll 6 between them, the film 12 generates tension. Through the pulling force and friction force, the first tension roller 5 and the second tension roller 7 can rotate. Since the film 12 has tension, it can avoid the film 12 from being loose or wrinkled during the laminating process.

[0032] The personnel install the auxiliary laminating roller 16 on the outside of the paper tube 4 so that the outer edge of the auxiliary laminating roller 16 is in contact with the outer edge of the paper tube 4, so that the film 12 can be closely attached to the paper tube 4, so that the laminating effect is better;

[0033] The bracket 13 can raise the height of the No. 1 tensioning roller 5 , so that a height difference is formed between the No. 1 tensioning roller 5 and the No. 2 tensioning roller 7 , and thus a better tensioning effect is achieved due to the angle change caused by the height difference.

[0034] For example, Figure 1 , Figure 3 As shown, the two ends of the paper tube 4, the first tensioning roller 5, the film roll 6 and the second tensioning roller 7 are respectively provided with a first bearing seat 8, a second bearing seat 9, a third bearing seat 10 and a fourth bearing seat 11.

[0035] When in use, the No. 1 bearing seat 8, the No. 2 bearing seat 9, the No. 3 bearing seat 10 and the No. 4 bearing seat 11 can respectively facilitate the smooth rotation of the paper tube 4, the No. 1 tensioning roller 5, the film roll 6 and the No. 2 tensioning roller 7.

[0036] For example, Figure 1 , Figure 3 As shown, the output end of the first synchronous motor 2 is connected to the paper tube 4.

[0037] When in use, the first synchronous motor 2 can drive the paper tube 4 to rotate.

[0038] For example, Figure 1 , Figure 3 As shown, the output end of the second synchronous motor 3 is connected to the film roll 6 .

[0039] When in use, the second synchronous motor 3 can drive the film roll 6 to rotate.

[0040] For example, Figure 1 As shown, the bottom of the second bearing seat 9 is connected to the base plate 1 through a bracket 13.

[0041] When in use, the bracket 13 can support the No. 1 tensioning roller 5 and the No. 2 bearing seat 9 , and can make the height of the No. 1 tensioning roller 5 higher than the height of the No. 2 tensioning roller 7 .

[0042] For example, Figure 1 As shown, bases 14 are provided at both ends of the bottom of the base plate 1 .

[0043] When in use, the base 14 can support the base plate 1 .

[0044] For example, Figure 2 As shown, the paper tube 4, the first tensioning roller 5, the film roll 6 and the second tensioning roller 7 are all provided with a central rod 15 inside.

[0045] When in use, both ends of the center rod 15 are connected to the bearing seats.

[0046] When the present invention is used, a person places the paper tube 4 to be coated between the first bearing seat 8, and passes one end of the film 12 on the outside of the film roll 6 through the top of the first tensioning roller 5 and the bottom of the second tensioning roller 7 to connect with the outside of the paper tube 4;

[0047] Further, the personnel turn on the No. 1 synchronous motor 2 and the No. 2 synchronous motor 3, and the No. 1 synchronous motor 2 can drive the paper drum 4 and the film roll 6 to rotate respectively. When the film 12 is stretched by the paper drum 4 and the film roll 6 between the paper drum 4 and the film roll 6, the film 12 generates tension. Through the pulling force and friction force, the No. 1 tensioning roller 5 and the No. 2 tensioning roller 7 can rotate. Because the film 12 has tension, it can avoid the film 12 from being loose or wrinkled during the lamination process.

[0048] Furthermore, by installing an auxiliary laminating roller 16 on the outside of the paper tube 4 so that the outer edge of the auxiliary laminating roller 16 is in contact with the outer edge of the paper tube 4, the film 12 can be closely attached to the paper tube 4, so that the laminating effect is better.

[0049] Furthermore, the bracket 13 can raise the height of the No. 1 tensioning roller 5 , so that a height difference is formed between the No. 1 tensioning roller 5 and the No. 2 tensioning roller 7 .
