Description

Technical Field

[0001] This utility model relates to the field of plastic film technology, specifically a multi-specification plastic film cutting machine. Background Technology

[0002] Plastic film is a thin, flexible material made primarily from resins such as polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). It has properties such as waterproofing, moisture resistance, and transparency, and is widely used in packaging, agriculture, and industry. Among these applications, food packaging accounts for the largest proportion, such as beverage packaging, frozen food packaging, retortable food packaging, and fast food packaging.

[0003] Regarding the above and existing related technologies: During the production of plastic film, it is necessary to cut the plastic film. During the cutting process, a support structure is used to support the plastic film roll. Most support structures lack adjustability, and the specifications of plastic films vary. When cutting plastic films of different specifications, the plastic film roll is prone to moving around, affecting the cutting effect. Therefore, a multi-specification plastic film cutting machine is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A multi-specification plastic film cutting machine of this utility model includes a machine body and a support device. The support device is disposed on one side of the machine body. A cutting part is fixedly connected to the upper surface of the machine body. A control part is fixedly connected to the side wall of the machine body. The support device includes a placement plate located on one side of the machine body. A support column is fixedly connected to the upper surface of the placement plate. A rotating rod is rotatably connected to the surface of the support column. A support plate is fixedly connected to the upper surface of the placement plate. The support plate is located directly above the rotating rod. The rotating rod rotates to the upper surface of the support plate. During cutting, the plastic film roll will rotate on the surface of the rotating rod. By setting the placement plate, support column, rotating rod and support plate, the plastic film roll can be supported.

[0006] Preferably, the inner wall of the rotating rod and the support plate is threaded with a fixing pin. After the rotating rod rotates to a suitable angle, the fixing pin is rotated to the inner wall of the rotating rod and the support plate. The fixing pin can limit the angle of the rotating rod.

[0007] Preferably, two stop bars are fixedly connected to the surface of the rotating rod. When the plastic film roll moves, the plastic film roll will be blocked by the stop bars, and the stop bars can limit the position of the plastic film roll.

[0008] Preferably, a sliding sleeve is slidably connected to the surface of the rotating rod, and four limiting rods are fixedly connected to the surface of the sliding sleeve. The sliding sleeve and the limiting rods will fit against the side wall of the plastic film roll. By setting the sliding sleeve and the limiting rods, the position of the plastic film roll can be restricted.

[0009] Preferably, the surface of the sliding sleeve is rotatably connected to a threaded sleeve, the inner wall of the threaded sleeve is threadedly connected to the surface of the rotating rod, and the threaded sleeve pushes the sliding sleeve to move its position. By setting the threaded sleeve, the position of the sliding sleeve can be easily moved, while the position of the sliding sleeve is restricted.

[0010] Preferably, the upper surface of the support column is provided with a limiting plate, which is located directly above the rotating rod. When the rotating rod rotates, the rotating rod rotates at the bottom end of the limiting plate. The limiting plate can restrict the position of the rotating rod on the surface of the support column.

[0011] Preferably, the side wall of the machine body and the side wall of the placement plate are provided with a limiting device. The limiting device includes a fixed plate, the side wall of the fixed plate and the side wall of the placement plate are fixedly connected, a rotating plate is rotatably connected to the surface of the fixed plate, and a locking block is fixedly connected to both sides of the side wall of the machine body near the rotating plate. A fixing rod is threadedly connected to the inner wall of the two locking blocks and the rotating plate. By rotating the fixing rod to the inner wall of the two locking blocks and the rotating plate, the position of the placement plate can be limited by setting the fixed plate, the rotating plate, the locking blocks and the fixing rod.

[0012] Preferably, a plurality of reinforcing rods are fixedly connected to the inner surface of the rotating plate. When the rotating plate is subjected to force, the rotating plate will transmit the force to the reinforcing rods, and the setting of the reinforcing rods can increase the strength of the rotating plate.

[0013] Preferably, a top plate is fixedly connected to the side wall of the machine body near the rotating plate. The top plate is located directly below the rotating plate. When the rotating plate rotates, the rotating plate will rotate to the upper surface of the top plate. The top plate can support the rotating plate.

[0014] Preferably, the surface of the card block is provided with a threaded hole, and the threaded hole of the card block is threadedly connected to the surface of the fixing rod. When the fixing rod rotates, the fixing rod rotates to rotate inside the threaded hole. The threaded hole facilitates the storage of the fixing rod.

[0015] The advantages of this utility model are:

[0016] 1. When cutting plastic film, this utility model involves placing a plastic film roll on the surface of a rotating rod, allowing the roll to adhere to the stop rod. A sliding sleeve is then placed on the surface of the rotating rod. Rotating the threaded sleeve causes it to rotate on both the sliding sleeve and the rotating rod surface, driving the sliding sleeve to move. This movement of the sliding sleeve, in turn, causes the limiting rod to move, pressing against the side wall of the plastic film roll. This pushes the rotating rod to rotate on the support column surface of the placement plate. After the rotating rod reaches the upper surface of the support plate, the fixing pin is rotated to the inner wall of the rotating rod and the support plate. As the plastic film roll rotates, it rotates between the stop rod and the limiting rod. This design supports the plastic film roll and accommodates different sizes of plastic film rolls, reducing the likelihood of the roll moving erratically.

[0017] 2. After the placement plate is placed in the appropriate position, the rotating plate is pushed to rotate on the surface of the fixed plate. When the rotating plate rotates to the position between the two locking blocks, it will rotate to the upper surface of the top plate. Then, the fixed rod is rotated to the inner wall of the locking blocks and the inner wall of the rotating plate. When the rotating plate is under force, the force will be transmitted to the reinforcing rod. By setting the entire device, the position of the placement plate can be restricted, reducing the situation of the placement plate moving randomly under force. Attached Figure Description
