Abstract
Description
Technical Field
[0001] This utility model relates to the field of wet wipe processing technology, specifically to an anti-misalignment pressing structure for a wet wipe folding device. Background Technology
[0002] During the production of wet wipes, misalignment during pressing (i.e., the upper and lower layers of material are not accurately aligned and pressed together) can lead to problems such as poor sealing, poor appearance, and even affect the usability of the product. When wet wipes are folded together, the folding rollers only have evenly spaced holes on their surface. Since wet wipes are often made of materials such as lint-free cloth, cotton, etc., the tension varies depending on the material after the grooves are pressed in, resulting in different rebounds. This can cause the wipes to protrude into the grooves of the rollers, causing folds, wrinkles, or outward protrusions when the pressure bar presses down. This results in the edges exceeding the set range, causing misalignment. Furthermore, the fixed structure of the rollers prevents adjustment of the width of the wet wipes, making it inconvenient to use. Therefore, a misalignment prevention pressing structure for wet wipe folding devices is designed to solve these problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4 This utility model provides a technical solution: an anti-misalignment pressing structure for a wet wipe folding device, comprising: two hollow rollers 1 with open ends; air nozzles 2 are connected in an array to the outer sides of the rollers 1; the inner sides of the air nozzles 2 communicate with the inner sides of the rollers 1; concave rollers 3 and convex rollers 4 are mounted in an array on the outer sides of the rollers 1; the lower ends of the concave rollers 3 and convex rollers 4 are connected to the outer sides of the rollers 1 by bolts; the interiors of the concave rollers 3 and convex rollers 4 communicate with the interiors of the air nozzles 2; and paper pressing grooves 5 are arrayed on the inner sides of the concave rollers 3 and convex rollers 4. A transmission rod 6 is provided at the lower end of the roller 1. A paper pressing rod 7 is fixedly connected to the outer side of the transmission rod 6. The paper pressing rod 7 is located inside the paper pressing groove 5. A reciprocating swing mechanism 8 is fixedly connected to the front end of the transmission rod 6. A transmission gear 9 is fixedly connected to the front end of the roller 1. A roller motor 10 is provided on one side of the front end of the roller 1. The output end of the roller motor 10 is driven by the front end of the transmission gear 9 through a chain. The motor of the reciprocating swing mechanism 8 and the roller motor 10 are both electrically connected to the PLC controller. The rear end of the roller 1 is connected to the suction end of the vacuum pump.
[0025] In use, roller 1, transmission rod 6, paper pressing rod 7, reciprocating oscillating mechanism 8, transmission gear 9, and roller motor 10 are all mounted on the bracket. Then, concave roller 3 and convex roller 4 are installed with bolts. The concave roller 3 and convex roller 4 on the two rollers 1 are positioned opposite each other. The speed of roller 1 and the speed of the reciprocating oscillating mechanism 8 motor are adjusted by the PLC controller. When the equipment is started for processing, the cut wet wipes are adsorbed onto the surface by the suction holes on the outer side of the upper concave roller 3. The two rollers 1 will then press the cut wet wipes together, and then the concave roller 3 will press them onto the surface. The groove is squeezed out at the contact point with the convex roller 4. Since the groove of the concave roller 3 also has an air suction hole, the wet wipe will not bounce back due to the tension on both sides of the groove. The reciprocating swing mechanism 8 will drive the paper pressing rod 7 to make a reciprocating bending motion. When pressing down and folding the wet wipe, it is not easy for the edges to fold together, so that the edges are thicker. The paper pressing rods 7 on the left and right sides can fold the wet wipe together by repeated folding. When it is necessary to adjust the width of the wet wipe, simply remove the bolts of the concave roller 3 and the convex roller 4 and replace them with wider or narrower modular concave roller 3 and convex roller 4.
[0026] like Figure 1-3 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, both sides of the concave roller 3 and the convex roller 4 are provided with protrusions and grooves, and the protrusions and grooves between two adjacent concave rollers 3 and convex rollers 4 are inserted and connected.
[0027] Analysis of the above structure shows that after installation, the protrusions and grooves fit together, which can increase stability and reduce the possibility of misalignment.
[0028] like Figure 1-3 As shown, this utility model embodiment provides an implementation method in which the interior of the concave roller 3 and the convex roller 4 is hollow.
[0029] Analysis of the above structure shows that the interiors of the concave roller 3 and the convex roller 4 are hollow, which can reduce weight and facilitate installation.
[0030] like Figure 1-3 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the connection between the concave roller 3 and the convex roller 4 and the air nozzle 2 is fitted with a sealing ring, and the outer side of the air nozzle 2 is sloped.
[0031] Analysis of the above structure shows that when installing the concave roller 3 and the convex roller 4, the outer side of the air nozzle 2 is sloped, which allows the air nozzle 2 to fit more tightly with the sealing ring of the inner hole of the concave roller 3 and the convex roller 4, thus improving air tightness.
[0032] like Figure 1-3As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the end of the paper pressing rod 7 is sloping, and the tilt angle of the end of the paper pressing rod 7 is the same as the swing angle of the paper pressing rod 7.
[0033] Analysis of the above structure shows that the end of the paper pressing rod 7 is sloping. When the paper pressing rod 7 swings to the end, the end of the paper pressing rod 7 will be horizontal, further preventing the wet wipes from being misaligned.
[0034] like Figure 1-3 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, the rear end of the roller 1 is connected to a gas passage rotary joint 21 through a flange, and the rear end of the gas passage rotary joint 21 is connected to the suction end of the vacuum pump.
[0035] Analysis of the above structure shows that the air circuit rotary joint 21 can ensure the stability of the air circuit during the rolling process of the roller 1.
[0036] like Figure 1-4 As shown, this utility model embodiment provides an implementation method. Based on the above implementation method, a gasket 22 is provided at the lower end of the connection between the concave roller 3 and the convex roller 4 and the drum 1. The lower surface of the gasket 22 is arc-shaped, and the radius of the arc at the lower end of the gasket 22 is the same as the outer radius of the concave roller 3 and the convex roller 4.
[0037] Analysis of the above structure shows that the lower surface of the gasket 22 at the connection between the concave roller 3 and the convex roller 4 and the drum 1 can be attached to the outer surface of the concave roller 3 and the convex roller 4. When the bolts are tightened, the friction can be increased and the stability can be improved.
