Description

Technical Field

[0001] The utility model belongs to the field of paper tube production equipment, in particular to a paper tube production flattening device. Background Art

[0002] Paper tubes, also known as paper tubes or cardboard tubes, are tubular objects made from paper or cardboard. They are widely used in a variety of industries, including chemical fiber, film, printing, papermaking, and metallurgy. Paper tubes typically possess high compressive and dynamic strength, effectively protecting the contents while facilitating storage and transportation. Most paper tubes are spiral or seamless, and are widely used in various fields. Prior to manufacturing, the raw paper must be flattened to ensure the quality of the tubes.

[0003] Currently, the most common method for flattening the raw material paper for paper tubes is to directly squeeze the base paper. However, this method has obvious drawbacks: it fails to ensure that the wrinkles on the base paper are fully flattened before the flattening force is applied. As a result, the wrinkles are further folded during the flattening process, which has a negative impact on the subsequent paper tube processing.

[0004] To this end, the utility model provides a paper tube production flattening device. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the utility model to solve its technical problems is: a paper tube production flattening device described in the utility model includes a conveying frame; the top of the conveying frame is fixedly connected to a fixed plate, the bottom of the fixed plate is fixedly connected to a support plate, one side of the fixed plate is fixedly connected to a cylinder, one end of the cylinder is fixedly connected to a push block, the push block slides on the support plate, both sides of the push block are hinged with connecting rods, one end of the connecting rod is fixedly connected to a spring, one end of the spring is fixedly connected to a sleeve, the connecting rod is sleeved with the sleeve, one end of the sleeve is hinged with a fixed block, the bottom end of the fixed block is fixedly connected to the conveying frame, the bottom of the connecting rod is fixedly connected to a plurality of support rods, and the bottom of the support rod is fixedly connected to a flattening block. During operation, after the base paper is placed on the surface of the conveyor frame, the cylinder is started, and the cylinder pushes the push block to perform reciprocating motion. The push block slides on the support plate, and the movement of the push block pushes the connecting rod to move. The connecting rod is hinged to the push block, and the spring connects the connecting rod and the sleeve. The movement of the connecting rod pushes the spring into the sleeve, and the sleeve follows the movement of the connecting rod and swings at the fixed block. Driven by the push block, the movement trajectory of the connecting rod is fan-shaped, ensuring that the flattening block is also driven to perform fan-shaped motion. The flattening block contacts the surface of the base paper and pushes the wrinkles of the base paper to both sides. By setting a connecting rod to drive the flattening block to perform fan-shaped motion, the flattening block pushes the wrinkles on the base paper to both sides, reducing the wrinkles from being transmitted and formed on the base paper, speeding up the flattening speed of the base paper, and promoting the production process of paper tubes.

[0007] Preferably, an elastic rope is fixedly connected between the flattening blocks, and a roller is rotatably connected to the outer side of the elastic rope. During operation, when the flattening block reciprocates on the surface of the base paper, its power will drive the elastic rope to stretch, and then the roller will closely contact the surface of the base paper to efficiently flatten the base paper. By setting a combination of the elastic rope and the roller, the gaps between the flattening blocks can be effectively filled, thereby achieving a more comprehensive and detailed flattening effect on the base paper.

[0008] Preferably, baffles are provided on both sides of the elastic rope, and the baffles are fixedly connected to the flattening block. During operation, the elastic rope reciprocates under the drive of the flattening block, and the baffles effectively limit the elastic rope. In this process, the baffles produce a unique effect through their bent shape, which significantly enhances the tension of the elastic rope. This design not only ensures the stable operation of the elastic rope, but also avoids accidental collision between the drum and the flattening block, thereby effectively preventing the base paper from being damaged due to squeezing.

[0009] Preferably, an external air pipe is provided on the top of the flattening block, and the external air pipe is connected to the flattening block. When working, the external air pipe introduces hot air into the system, and through heat conduction, the hot air is evenly sprayed on the surface of the base paper. Through this arrangement, the base paper is effectively softened, which makes it easier for the flattening block to accurately flatten the wrinkles on its surface, and also provides a smoother operating environment for subsequent processing steps.

[0010] Preferably, a plurality of sponge blocks are fixedly provided at the bottom of the flattening block, and the sponge blocks are arranged in a hemispherical shape. When working, the hot air introduced by the external air pipe is evenly distributed through the sponge blocks. In this process, the sponge blocks are driven by the flattening block to gently pass over the surface of the base paper, thereby achieving deep cleaning and finishing of the surface of the base paper.

[0011] Preferably, a protective cover is provided on the top of the conveyor frame, and the protective cover is fixedly connected to both sides of the conveyor frame. When working, the arched design of the protective cover is used to provide comprehensive protection for the conveyor frame, and the holes on its surface are intended to promote the smooth dissipation of hot air after acting on the base paper.

[0012] The beneficial effects of the utility model are as follows:

[0013] 1. The utility model describes a paper tube production flattening device, which drives the flattening block to perform fan-shaped movement by setting a connecting rod. The flattening block pushes the wrinkles on the base paper to both sides, reduces the wrinkles from being transmitted and formed on the base paper, speeds up the flattening speed of the base paper, and promotes the production process of paper tubes.

[0014] 2. The paper tube production flattening device described in the present invention evenly distributes the hot air introduced by the external air pipe through the sponge block. During this process, the sponge block, driven by the flattening block, gently passes over the surface of the base paper, thereby achieving deep cleaning and finishing of the base paper surface.

The push block 13 slides on the support plate 111, and connecting rods 14 are hinged on both sides of the push block 13. One end of the connecting rod 14 is fixedly connected to a spring 15, and one end of the spring 15 is fixedly connected to There is a sleeve 16, the connecting rod 14 is sleeved with the sleeve 16, one end of the sleeve 16 is hinged with a fixed block 17, the bottom end of the fixed block 17 is fixedly connected to the conveyor frame 1, the bottom of the connecting rod 14 is fixedly connected to a plurality of support rods 18, the bottom of the support rod 18 is fixedly connected to a flattening block 19, and the flattening block 19 is driven to perform a fan-shaped movement by setting the connecting rod 14. The flattening block 19 pushes the wrinkles on the base paper to both sides, reducing the wrinkles from being transmitted and formed on the base paper, speeding up the flattening speed of the base paper, and promoting the production process of paper tubes.

[0024] like Figures 1 to 4 As shown, an elastic rope 2 is fixedly connected between the flattening blocks 19, and a roller 21 is rotatably connected to the outer side of the elastic rope 2. When the flattening block 19 reciprocates on the surface of the base paper, its power will drive the elastic rope 2 to stretch, and then the roller 21 will closely contact the surface of the base paper to efficiently flatten the base paper. By setting a combination of the elastic rope 2 and the roller 21, the gaps between the flattening blocks 19 can be effectively filled, thereby achieving a more comprehensive and detailed flattening effect on the base paper.

[0025] like Figures 1 to 4 As shown, baffles 3 are provided on both sides of the elastic cord 2, and the baffles 3 are fixedly connected to the flattening block 19. The elastic cord 2 reciprocates under the drive of the flattening block 19, and the baffles 3 effectively limit the elastic cord 2. In this process, the baffles 3 produce a unique effect through their bent shape, which significantly enhances the tension of the elastic cord 2. This design not only ensures the stable operation of the elastic cord 2, but also avoids accidental collision between the roller 21 and the flattening block 19, thereby effectively preventing the base paper from being damaged due to squeezing.

[0026] like Figures 1 to 4As shown, an external air pipe 4 is provided on the top of the flattening block 19, and the external air pipe 4 is connected to the flattening block 19. The external air pipe 4 introduces hot air into the system and sprays the hot air evenly on the surface of the base paper through heat conduction. Through this arrangement, the base paper is effectively softened, which makes it easier for the flattening block 19 to accurately flatten the wrinkles on its surface, and also provides a smoother operating environment for subsequent processing steps.

[0027] like Figures 1 to 4 As shown, a plurality of sponge blocks 5 are fixedly provided at the bottom of the flattening block 19. The sponge blocks 5 are arranged in a hemispherical shape. The hot air introduced by the external air pipe 4 is evenly distributed through the sponge blocks 5. During this process, the sponge blocks 5 are driven by the flattening block 19 to gently pass over the surface of the base paper, thereby achieving deep cleaning and finishing of the surface of the base paper.

[0028] like Figures 1 to 5 As shown, a protective cover 6 is provided on the top of the conveyor frame 1, and the protective cover 6 is fixedly connected to both sides of the conveyor frame 1. The arched design of the protective cover 6 is used to provide comprehensive protection for the conveyor frame 1, and the holes on its surface are intended to promote the smooth dissipation of hot air after acting on the base paper.

[0029] Working principle: After the base paper is placed on the surface of the conveyor frame 1, the cylinder 12 is started, and the cylinder 12 pushes the push block 13 to reciprocate. The push block 13 slides on the support plate 111, and the push block 13 moves and then pushes the connecting rod 14 to move. The connecting rod 14 is hinged to the push block 13, and the spring 15 connects the connecting rod 14 and the sleeve 16. The movement of the connecting rod 14 pushes the spring 15 to squeeze into the sleeve 16. The sleeve 16 follows the movement of the connecting rod 14 and swings at the fixed block 17. Driven by the push block 13, the movement trajectory of the connecting rod 14 is fan-shaped, ensuring that the paper is brought in. The dynamic flattening block 19 also performs fan-shaped motion, and the flattening block 19 contacts the surface of the base paper, pushing the wrinkles of the base paper to both sides. When the flattening block 19 reciprocates on the surface of the base paper, its power drives the elastic rope 2 to stretch. Subsequently, the roller 21 will closely contact the surface of the base paper and flatten the base paper efficiently. By setting the combination of the elastic rope 2 and the roller 21, the gap between the flattening blocks 19 can be effectively filled, thereby achieving a more comprehensive and detailed flattening effect on the base paper. The elastic rope 2 is driven by the flattening block 19 to move The baffle 3 effectively limits the elastic cord 2 and, in this process, produces a unique effect through its bent shape, significantly enhancing the tension of the elastic cord 2. This design not only ensures the stable operation of the elastic cord 2, but also avoids accidental collision between the roller 21 and the flattening block 19, thereby effectively preventing the base paper from being damaged by squeezing. The external air pipe 4 introduces hot air into the system and sprays the hot air evenly on the surface of the base paper through heat conduction. By this arrangement, the base paper is effectively moistened and Softening treatment makes it easier for the flattening block 19 to accurately flatten the wrinkles on its surface, and also provides a smoother operating environment for subsequent processing steps. The hot air introduced by the external air pipe 4 is evenly spread through the sponge block 5. In this process, the sponge block 5 is driven by the flattening block 19 to gently pass over the surface of the base paper, thereby achieving deep cleaning and sorting of the surface of the base paper. The arched design of the protective cover 6 is used to provide comprehensive protection for the conveyor frame 1, and the holes on its surface are intended to promote the smooth dissipation of hot air after acting on the base paper.
