Description

Technical Field

[0001] The utility model relates to the technical field of film production, in particular to a convenient punching wheel supporting structure. Background Art

[0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins, used for packaging and as a coating layer. Plastic packaging and plastic packaging products occupy an increasingly large share in the market. These products have brought great convenience to people's lives. In the process of plastic film production, it is necessary to punch holes in it, which requires the use of a punching device.

[0003] In the existing punching device, the space for re-receiving or feeding the film material during the punching process is narrow, resulting in the film material being unable to be fed through the film quickly and efficiently, and unable to achieve fast and convenient punching of film materials, so there is room for improvement. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and propose a convenient punching wheel support structure. Its advantages are that it allows film materials to be quickly and efficiently fed through the film in a large space, and at the same time, it can efficiently and quickly change the punching density adjustment work of film products.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The punching wheel fixing seat is rotatably connected with a punching wheel group at one end away from the guide rod, and the punching wheel group includes a punching wheel protective shell, and the punching wheel protective shell is connected to the punching wheel fixing seat through a tension spring, and the inner walls of both sides of the punching wheel protective shell are connected to a hole needle fixing wheel through a slewing bearing, and the surface of the hole needle fixing wheel is provided with a plurality of hole needle fixing holes distributed in an annular manner with equal distances, and the inner walls of the hole needle fixing holes are plugged with hole needles;

[0008] The outer wall of the rotating shaft is sleeved with a punching auxiliary wheel. When the punching wheel set is in a closed state, the punching needle fixing wheel contacts the punching auxiliary wheel.

[0009] Through the above technical scheme: personnel open the punching wheel group to the open state, and when the space is large in the open state of the punching wheel group, personnel pass the film between the punching wheel group and the punching auxiliary wheel, and then put the punching wheel group to the closed state, at this time the punching wheel support structure meets the working turntable; in this process, the guide rod provides fixation and sliding of all supporting components, and the locking mechanism can be locked and fixed in the appropriate position; the hole needle fixing wheel in the punching wheel group is used to fix the hole needle, and the hole needle fixing wheel can realize cyclic work under the rotation of the slewing bearing; the rotating shaft in the punching auxiliary wheel provides support; the tension spring provides balanced force for the punching wheel group in the open state and the closed state, which can stabilize the balance and stability of the mechanism and conveniently improve the film roll feeding work; all accessories are organically combined so that the film punching wheel can be reliably supported, which is convenient for users to work efficiently.

[0010] The utility model is further configured that the cross section of the guide rod is a square structure.

[0011] Through the above technical solution: the design of the square structure in cross section can limit the punch wheel fixing seat to avoid the punch wheel fixing seat from rotating during operation.

[0012] The utility model is further configured that the locking mechanism includes a threaded hole opened on the top of the punching wheel fixing seat, the inner wall of the threaded hole is connected with a locking handle through a thread, and the bottom of the locking handle is in contact with the guide rod.

[0013] Through the above technical solution: the locking handle is rotated by hand, and the locking handle moves downward while rotating. When the bottom of the locking handle contacts the guide rod, the punching wheel fixing seat can be locked under the action of friction to prevent it from sliding.

[0014] The utility model is further configured that a locking wheel is arranged on the top of the locking handle, and a plurality of anti-slip convex ribs distributed at equal distances are arranged on the outer wall around the locking wheel.

[0015] Through the above technical solution: the provision of anti-skid convex ribs can increase the friction between the palm and the locking wheel when turning the locking handle, avoid slipping, and improve the convenience of operation.

[0016] The utility model is further configured that a pressing sheet is provided at the bottom of the locking handle, and the pressing sheet is made of rubber material.

[0017] Through the above technical solution: when the locking handle is turned, the pressing plate will be squeezed and deformed when it contacts the guide rod, thereby increasing the friction between the locking handle and the guide rod and improving the locking effect.

[0018] The utility model is further configured that the hole needle is made of stainless steel.

[0019] Through the above technical solution: the hole needle made of stainless steel has higher strength and corrosion resistance, which improves the drilling quality and service life of the hole needle.

[0021] 1. A convenient punching wheel support structure is designed to solve the problem of narrow space for re-connecting or feeding thin film materials in the market. It can integrate the punching wheel fixing seat, punching wheel group, punching auxiliary wheel, punching wheel group connecting pin, tension spring and surrounding accessories to work together organically to meet the online punching of thin film materials, and can also be opened quickly and conveniently for film penetration or position adjustment. In this process, users can work in groups simultaneously or separately, and open and close the punching wheel efficiently and conveniently, thereby realizing fast and convenient punching of thin film materials.

[0022] 2. A convenient punching wheel support structure re-plans the combination mode of the mechanism and adjusts the matching link position of the mechanism, making the punching of the film and the adjustment of the punching density more efficient, energy-saving and miniaturized. At the same time, more adjustment structures and interchangeable modules are designed, so that the film punching process can work conveniently and reliably; it enables film materials to be quickly and efficiently fed through the film in a larger space, and at the same time, the punching density adjustment work of film products can be changed efficiently and quickly.
