Description

A rewinding device for food packaging film production

Technical field

The utility model relates to a rewinding device, in particular to a rewinding device for food packaging film production, which belongs to the technical field of rewinding devices.

Background technique

After the production of food packaging film is completed, it is usually divided and rolled into a cylinder to facilitate its subsequent transportation and use. A winding mechanism is generally used. The winder is the rewinding part of the coil processing production line. It is a piece of machinery and equipment that can mechanically rewind raw materials into coils. In daily life, they are mostly used in paper rolls, cloth rolls, plastic rolls, and metal coil processing production lines. It is powered by a variable frequency motor and is an active rewinder. The rewinder and tensioner (or rolling mill) can provide large tension for the rewinding section, which can be divided into upper rewinding and lower rewinding.

Existing smaller winding mechanisms generally wind up the film body through the rotation of the drum. In the process, in order to ensure the close fit between the film bodies, the film body is usually in a tight state and becomes more aligned. The higher the tightness requirement, the greater the tension force on the membrane body. This method may cause the membrane body to be deformed due to greater force. At the same time, the winding may not be compliant due to the sliding of the membrane body or the existence of wrinkles. Or there will be deviation. In addition, when the film body is cut, the end part will often not fit tightly due to lack of tension. Therefore, a rewinding device for food packaging film production is proposed to solve the above problems.

Utility model content

The technical problem to be solved by this utility model is to provide a rewinding device for food packaging film production. The rewinding device can squeeze and transport the film body at a constant speed through the feeding roller group, while flattening the surface wrinkles of the film body due to The great friction between it and the film body will make it difficult for the film body to slide, ensuring that the film body entering the rewinding mechanism is not easily deflected, and the smoothing frame provided behind the rewinding mechanism can prevent the film body from being rolled up. When the roll is on the roll, give it a pressing force to make it fit more closely, thereby reducing the tension exerted by the overall mechanism on the film body and protecting the film body. When the film body is cut, its end can be smoothed. It tightly fits on the rewinding drum under the pressure of the frame, which solves the problem in the prior art that the film body is tightly deformed due to the tensile force and the film body is easy to slide or has wrinkles during the rewinding process, causing the film body to be retracted. The volume does not comply with technical issues.

To solve the above problems, the following technical solutions are provided:

Design a rewinding device for food packaging film production, including a bottom plate. A feeding roller group is fixedly installed at the front end of the bottom plate. A redirecting pressure roller group is fixedly installed at the middle position of the upper end of the base plate. The middle position of the upper end of the base plate is A rewinding mechanism is fixedly installed at the rear of the reversing pressure roller group. A mounting end plate is fixed at the upper edge of the rear end of the bottom plate. The mounting end plate is fixed at the center of the side facing the rewinding mechanism. A telescopic rod is installed, and a smoothing frame is fixedly installed at the end of the rod body at the telescopic end of the telescopic rod.

The above structure is used to squeeze and feed the film through the feeding roller group during the feeding process, which can smooth out the wrinkles on the surface of the film and make the film less likely to slide during movement. The redirected pressure roller group plays a transfer role. It can ensure the horizontal feeding of the feeding roller group, and the smoothing frame can give the film body a pressing force when it is rolled up on the winding mechanism to make it fit more closely, thereby reducing the tension exerted by the overall mechanism on the film body. , which plays a protective role in the film body. When the film body is cut, its end can still fit tightly on the winding mechanism under the pressure of the smoothing frame.

Further, the feeding roller group includes a first mast, a first hydraulic cylinder is fixedly installed at the center of the lower end surface of the top beam of the first mast, and a first installation is fixedly installed at the end of the output shaft of the first hydraulic cylinder. rack, and an electric drum set is installed below the first mounting rack.

The above structural form enables the electric roller group to move up and down driven by the first hydraulic cylinder, ensuring that it can be in close contact with membrane bodies of different thicknesses and materials, and preventing it from slipping with the membrane body during the rotation and feeding process. causing the membrane to shift.

Further, a feeding trough is provided on the bottom plate directly below the electric roller group, and a driven roller group is rotated in the feeding trough.

The above-mentioned structural form causes the lower end surface of the membrane body to also receive the extrusion force from the driven roller group, so that the membrane body is clamped up and down during the transportation process, and sliding deviation is less likely to occur.

Furthermore, the outer side of the electric roller group is fixedly wrapped with a sleeve layer, and the outer side of the driven roller group is fixedly wrapped with a sleeve layer. The sleeve layer is a soft rubber sleeve made of frosted material.

The above-mentioned structural form can effectively enhance the friction between the film body, the electric drum set, and the driven drum set, thereby effectively preventing the film body from sliding and deflecting during movement and affecting the winding effect.

Further, the redirection pressure roller group includes a second mast, a second hydraulic cylinder is fixedly installed at the center of the lower end surface of the top beam of the second mast, and a third hydraulic cylinder is fixedly installed at the end of the output shaft of the second hydraulic cylinder. Two mounting brackets, a rotating drum is rotatably provided under the second mounting bracket.

The above structure can ensure that the feeding roller group always feeds the material horizontally. Since the winding mechanism continuously rewinds the film body, its diameter will continue to change. If the feeding roller group is not added, the angle of the film body at the output end of the feeding roller group will continue to change, causing it to be in contact with the film body. The direction and magnitude of the friction force between the feeding roller groups are constantly changing, which can easily cause relative sliding between the film body and the feeding roller group.

Further, the rewinding mechanism includes an end bracket, an electric rewinding drum is fixedly installed on the end bracket, and cylinder end plates are fixedly installed at both ends of the electric rewinding drum at inner positions of the end bracket.

The above-mentioned structural form can continuously roll up the film transported by the feeding roller group through its own rotation.

Further, the smoothing frame includes a connecting rod, and application curved plates are fixedly provided at both ends of the connecting rod.

The above structural form can exert a pressing force on the film body to be rolled up by being close to the winding drum, so that it can fit more closely, and because the convex surface of the curved plate is applied outward, the surface in contact with the film body is smooth and smooth. The edges and corners will not damage the membrane structure.

Compared with the existing technology, the beneficial effects of this utility model are:

In this utility model, the film body is extruded and transported at a constant speed through the set of feeding rollers. While the wrinkles on the surface of the film body are compacted, the friction between the film body and the film body is extremely large, which makes it difficult for the film body to slide, ensuring that it enters the collection. The film body in the winding mechanism is not easy to deflect, and the smoothing frame provided behind the winding mechanism can give the film body a pressing force when it is rolled onto the winding drum to make it fit more closely, thereby reducing the risk of The tension exerted by the overall mechanism on the membrane body protects the membrane body. When the membrane body is cut, its end can still fit tightly on the winding drum under the pressure of the smoothing frame;
