Description

Technical Field

[0001] This application relates to the field of paper lamination and rolling technology, specifically to an anti-extrusion pit paper lamination and rolling device. Background Technology

[0002] With the rapid development of the paper packaging industry, the demand for anti-compression corrugated paper is increasing. While improving production efficiency, existing corrugated paper production equipment faces the challenge of ensuring the quality and stability of corrugated paper. Although traditional corrugated paper laminating and rolling equipment can achieve basic lamination functions, on high-speed production lines, it is easy for corrugated paper to deform and wrinkle during the lamination process, which seriously affects the quality of the final product. At present, in order to improve the quality of corrugated paper lamination, the following methods are commonly used.

[0003] 1. Using a multi-layer roller combination increases the bonding pressure and uniformity by increasing the number of rollers, effectively improving the bonding strength of corrugated paper. However, the multi-layer rollers increase the complexity of the equipment and maintenance costs, and vibrations during high-speed operation can lead to unevenness on the corrugated paper surface. 2. Using air-cushion bonding rollers allows for flexible adjustment of bonding pressure by inflating the rollers, adapting to corrugated paper of different thicknesses. However, air-cushion systems are prone to leakage, requiring frequent maintenance, and uneven gas distribution within the air cushion can lead to unstable bonding results over long periods of operation. 3. Using... Using elastic rubber rollers absorbs impact force through the elastic properties of rubber, reducing the deformation of corrugated paper during the lamination process and providing a good cushioning effect. However, rubber is prone to aging in high-temperature environments, resulting in a short service life, and it easily loses elasticity under high pressure, leading to a decrease in lamination effect. Although the above technology can improve the lamination quality of corrugated paper to a certain extent, it is inconvenient to promptly notify staff to stop and repair the rolling device when phenomena such as uneven paper surface, air leakage, and aging caused by vibration occur. This results in poor product controllability, an increase in the production of defective products, and a high scrap rate. Utility Model Content

[0012] Furthermore, a dual-axis motor is fixed to the left side wall of the inner cavity of the frame plate, and the ends of the two rotating rods away from the second oblique bevel teeth are fixed to the output end of the dual-axis motor.

[0013] The above technical solution is adopted so that the two rotating rods can be driven to rotate within the frame plate, thereby enabling the two rotating rods to drive the two second oblique bevel teeth to rotate within the frame plate.

[0014] Furthermore, both ends of the two screws are rotatably connected to the upper and lower walls of the inner cavity of the frame plate via bearings.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figures 1 to 5 The anti-squeezing corrugated paper bonding and rolling device in this embodiment includes two conveying mechanisms 1. A cooling mechanism 2 is fixed at the front end of the right conveying mechanism 1. A support frame 3 is provided on the opposite side of the two conveying mechanisms 1. A rolling structure is provided inside the support frame 3. The rolling structure includes two narrow plates 31, two hydraulic cylinders 32, a concave plate 33, two sets of pressure rollers 34 and two pressure sensors 35. A detection component is provided inside the support frame 3.

[0032] In addition, the two narrow plates 31 are fixed to the rear wall inside the support frame 3, the output ends of the two hydraulic cylinders 32 are fixed to the front end of the concave plate 33, and the upper and lower ends of the two sets of pressing rollers 34 are rotatably connected to the upper and lower walls inside the concave plate 33 and the opposite wall of the two narrow plates 31 through bearings.

[0033] Furthermore, the front end of the support frame 3 has two fixing holes, through which the hydraulic cylinder 32 can be fixed to the support frame 3, so that the two hydraulic cylinders 32 can drive the front pressing roller 34 to move inside the support frame 3 via the concave plate 33, so that the front pressing roller 34 can cooperate with the rear pressing roller 34 to roll the corrugated paper.

[0034] Furthermore, the front ends of both narrow plates 31 are provided with mounting holes for fixing the pressure sensor 35 inside. When the concave plate 33 drives the front pressing roller 34 to fit with the rear pressing roller 34, the concave plate 33 squeezes the pressure sensor 35 so that the rolling pressure can be adjusted in time.

[0035] Furthermore, the pressing roller 34 includes a cylinder 341 and a gasket 342. The gasket 342 is fixed to the surface of the cylinder 341. The gasket 342 is a polyurethane gasket, which can absorb some of the impact force during the bonding process, reduce the deformation of the corrugated paper, and protect the surface of the cylinder 341 from damage, thereby further improving the bonding effect and reducing wear.

[0036] Please see Figure 3 and Figure 5 The detection component in this embodiment includes a frame plate 41, two movable plates 42, a laser rangefinder 43 fixedly installed on one wall opposite to the front and rear movable plates 42, an ultrasonic sensor 44 fixedly installed on one wall opposite to the front and rear movable plates 42, and a movable structure fixedly installed on one wall opposite to the two movable plates 42.

[0037] The frame plate 41 is fixed to the inner wall of the support frame 3. The frame plate 41 is a hollow plate to prevent the paper from being obstructed from moving to the right conveying mechanism 1.

[0038] Please see Figure 5 In this embodiment, the moving structure includes a moving block 45 fixed to one side of the two moving plates 42. The interior of each moving block 45 is threaded with a screw 46. The outer surface of each screw 46 is fixed with a first oblique bevel tooth 49. The opposite ends of each of the two first oblique bevel teeth 49 are engaged with a second oblique bevel tooth 48. The interior of each of the two second oblique bevel teeth 48 is fixed with a rotating rod 47.

[0039] Secondly, a dual-axis motor is fixed to the left side wall of the inner cavity of the frame plate 41. The ends of the two rotating rods 47 away from the second oblique bevel teeth 48 are fixed to the output end of the dual-axis motor so that the two rotating rods 47 can be driven to rotate inside the frame plate 41, thereby enabling the two rotating rods 47 to drive the two second oblique bevel teeth 48 to rotate inside the frame plate 41.

[0040] In addition, the upper and lower ends of the two screws 46 are rotatably connected to the upper and lower walls of the inner cavity of the frame plate 41 through bearings, so that the two screws 46 can rotate stably within the frame plate 41, so that the screws 46 can stably drive the moving block 45 to perform linear motion.

[0041] Meanwhile, each of the two moving blocks 45 has a through hole at its top for the screw 46 to pass through. The screw 46 is threaded to the inside of the through hole, so that the screw 46 can be threaded to the moving block 45 by connecting to the through hole, thereby driving the moving block 45 to move linearly within the frame plate 41.

[0042] Furthermore, both the front and rear walls of the inner side of the frame plate 41 are provided with elongated holes for the moving block 45 to pass through. The moving block 45 is slidably connected to the inner side of the elongated holes. The moving block 45 can pass through the elongated holes to exit the interior of the frame plate 41, so that the moving block 45 can drive the moving plate 42 to move inside the frame plate 41, thereby driving the detection end composed of the laser rangefinder 43 and the ultrasonic sensor 44 to move inside the frame plate 41, so that the detection end can repeatedly detect the surface of the corrugated paper.

[0043] It should be noted that the conveying mechanism 1, cooling mechanism 2, rolling structure, laser rangefinder 43, ultrasonic sensor 44, and the electronic components mentioned in this article are all commonly known in the prior art. The electrical components mentioned in this article are all connected to the controller and power supply. The control method of this embodiment is controlled by the controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also commonly known in the art. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0044] The working principle of the above embodiments is as follows:

[0045] During use, by fixing a pad 342 on the surface of the cylinder 341, some of the impact force is absorbed during the bonding process of the two sets of pressure rollers 34, reducing the deformation of the corrugated paper and protecting the surface of the cylinder 341 from damage. This further improves the bonding effect and reduces wear. After the corrugated paper is rolled out, when it is removed from the support frame 3, the detection end composed of a laser rangefinder 43 and an ultrasonic sensor 44 monitors the flatness and bonding thickness of the corrugated paper. This allows for real-time measurement of the flatness and thickness of the corrugated paper, thereby improving the controllability of product quality, reducing the generation of defective products, and lowering the scrap rate.

[0046] Furthermore, the output of the dual-axis motor drives two rotating rods 47 to rotate, which in turn drives the second helical bevel teeth 48 to rotate. These second helical bevel teeth 48 mesh with the two first helical bevel teeth 49, causing them to rotate. This, in turn, drives the two screws 46 to rotate. The screws 46 are threadedly connected to the through holes of the moving blocks 45, enabling them to drive the moving blocks 45 to move linearly within the frame plate 41. The two moving blocks 45 then drive the moving plates 42 to move linearly within the frame plate 41. This allows the two moving plates 42 to drive two detection ends, composed of laser rangefinders 43 and ultrasonic sensors 44, to monitor both sides of the corrugated paper back and forth. This increases the detection area of ​​the detection ends, further improving product quality controllability, reducing defective products, and lowering the scrap rate.
