Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic wrap processing, and in particular to a plastic wrap cutting device with a pressing structure. Background Technology
[0002] Plastic wrap is a type of plastic packaging product, usually made from ethylene through a polymerization reaction. Plastic wrap can be divided into three main categories: the first is polyethylene, abbreviated as PE; the second is polyvinyl chloride, abbreviated as PVC; and the third is polyvinylidene chloride, abbreviated as PVDC. Before use, plastic wrap needs to be cut into different sizes according to the size of different items.
[0003] In daily life, plastic wrap is widely used for food preservation. However, existing plastic wrap has many inconveniences in its use. When it is necessary to cut the plastic wrap, some cutting devices, although equipped with a cutting mechanism, are prone to slipping due to the lack of a clamping structure, resulting in uneven cutting and uneven cuts, which affects the effectiveness of use and cannot meet the demand for efficient and precise cutting of plastic wrap. To address these issues, we propose a plastic wrap cutting device with a clamping structure. Utility Model Content
[0004] The purpose of this invention is to provide a cling film cutting device with a pressing structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A cling film cutting device with a pressing structure includes a base platform. A U-shaped bridge is fixedly connected to the upper surface of the base platform. A fixing frame is fixedly connected to the upper surface of the U-shaped bridge. An electric push rod is fixedly connected to the inner wall of the fixing frame. A U-shaped connecting frame is fixedly connected to the output end of the electric push rod. A main pressing plate is fixedly connected to the bottom surface of the U-shaped connecting frame. A side connecting frame is fixedly connected to the outer surface of the U-shaped connecting frame. A secondary pressing plate is fixedly connected to the bottom surface of the side connecting frame. A rubber pressing layer is fixedly connected to the bottom surface of both the secondary pressing plate and the main pressing plate. Two guide grooves are formed in the inner wall of the U-shaped bridge. A sliding rod is slidably connected inside each guide groove. One end of each sliding rod is fixedly connected to the upper surface of the main pressing plate. A cutting component is fixedly installed on the upper surface of the side connecting frame. Two guide pillars are fixedly connected to the upper surface of the base platform. A square sliding plate is slidably connected to the outer surface of each guide pillar. The outer surface of each square sliding plate is fixedly connected to the upper surface of the secondary pressing plate.
[0007] In a further embodiment, the cutting assembly includes a blade holder cylinder, a guide slide column is slidably connected inside the blade holder cylinder, an L-shaped frame is fixedly connected to the front end of the guide slide column, a blade is fixedly connected to the rear end of the L-shaped frame, and a support handle is fixedly connected to the front end of the L-shaped frame.
[0008] In a further embodiment, a placement plate is fixedly connected to the upper surface of the base platform, and a cutting groove is formed on the upper surface of the placement plate.
[0009] In a further embodiment, the bottom surface of the base platform is fixedly connected to two support members, and the bottom surfaces of the two support members are jointly fixedly connected to a base plate.
[0010] In a further embodiment, a control button is fixedly connected to the front of the U-shaped cable tray, and the control button is electrically connected to an electric push rod via a wire.
[0011] In a further embodiment, two guide blocks are fixedly connected to the left side of the U-shaped cable tray, and guide grooves are provided on the adjacent side of the two guide blocks.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This device uses an electric push rod to move the U-shaped connecting frame and its connected main and secondary clamping plates downwards. The rubber clamping layer on the bottom surface of the main and secondary clamping plates makes close contact with the cling film, firmly pressing the cling film onto the placement plate. This achieves a secure clamping of the cling film, and the rubber clamping layer not only increases friction to prevent the cling film from slipping during cutting but also avoids damage to the cling film. This clamping structure effectively ensures the stability of the cling film during cutting, ensuring accurate and smooth cutting operations. The cutting blade in the cutting assembly is slidably connected to the guide slide column within the blade holder cylinder via the L-shaped frame, enabling the blade to move back and forth and perform cutting actions. The operation is simple and intuitive. Furthermore, the cutting groove on the placement plate provides the blade with an accurate cutting path, resulting in neater and more precise cuts.

A U-shaped bridge 4 is fixedly connected to the upper surface of the base platform 1. A fixing frame 5 is fixedly connected to the upper surface of the U-shaped bridge 4. An electric push rod 6 is fixedly connected to the inner wall of the fixing frame 5. A U-shaped connecting frame 10 is fixedly connected to the output end of the electric push rod 6. A main pressing plate 11 is fixedly connected to the bottom surface of the U-shaped connecting frame 10. A side connecting frame 15 is fixedly connected to the outer surface of the U-shaped connecting frame 10. A secondary pressing plate 16 is fixedly connected to the bottom surface of the side connecting frame 15. A rubber pressing layer 12 is fixedly connected to the bottom surface of both the secondary pressing plate 16 and the main pressing plate 11. Two guide grooves 13 are opened on the inner wall of the U-shaped bridge 4. A sliding rod 14 is slidably connected inside each guide groove 13. One end of each sliding rod 14 is fixedly connected to the upper surface of the main pressing plate 11. The upper surface of the side connecting frame 15 is fixedly connected to the main pressing plate 11. The base platform 1 is equipped with a cutting assembly 26. Two guide rods 17 are fixedly connected to the upper surface of the base platform 1. A square slide plate 18 is slidably connected to the outer surface of each guide rod 17. The outer surface of each square slide plate 18 is fixedly connected to the upper surface of the secondary pressing plate 16. During the up-and-down movement of the main pressing plate 11, it slides in the guide groove 13 on the inner wall of the U-shaped bridge frame 4 through the sliding rod 14, providing stable guidance for the movement of the U-shaped connecting frame 10 and the main pressing plate 11, ensuring that they can smoothly press the plastic wrap. The secondary pressing plate 16 slides on the guide rods 17 through the square slide plate 18, which further ensures the stability of the movement of the secondary pressing plate 16. These structures together ensure that the various components of the equipment can maintain a stable relative position during the entire pressing and cutting operation, avoiding shaking, displacement, etc., extending the service life of the equipment, and ensuring the continuous and effective operation of the cutting work.
[0024] The cutting assembly 26 includes a blade holder cylinder 19, with a guide slide column 20 slidably connected inside the blade holder cylinder 19. An L-shaped frame 21 is fixedly connected to the front end of the guide slide column 20, and a blade 22 is fixedly connected to the rear end of the L-shaped frame 21. A support handle 23 is fixedly connected to the front of the L-shaped frame 21. The operator can easily push the blade 22 to perform the cutting action through the support handle 23, making the operation simpler. A placement plate 7 is fixedly connected to the upper surface of the base platform 1. A cutting groove 8 is opened on the upper surface of the placement plate 7. The cutting groove 8 on the placement plate 7 provides an accurate cutting path for the blade 22, making the cutting more neat.
[0025] Two support members 2 are fixedly connected to the bottom surface of the base platform 1. The bottom surfaces of the two support members 2 are jointly fixedly connected to the bottom pad 3, making the device more stable during use. A control button 9 is fixedly connected to the front of the U-shaped bridge 4. The control button 9 is electrically connected to the electric push rod 6 through a wire. The operator only needs to press the control button 9 to easily control the extension and retraction of the electric push rod 6, thereby realizing the pressing and releasing operation of the main pressing plate 11 and the secondary pressing plate 16. The operation is simple and convenient. Two guide blocks 24 are fixedly connected to the left side of the U-shaped bridge 4. The two guide blocks 24 are provided with guide grooves 25 on the adjacent side, which can allow the plastic wrap to move within the guide grooves 25, ensuring stable placement and preventing tilting.
[0026] The working principle of this utility model is as follows:
[0027] After the device is securely placed, the plastic wrap to be cut is passed through the U-shaped bridge 4 and placed on the placement plate 7. Once it is flat, the electric push rod 6 can be activated to push the U-shaped connecting frame 10 and the main pressing plate 11 downward. At the same time, when the U-shaped connecting frame 10 moves, it will move the auxiliary pressing plate 16 downward synchronously through the side connecting frame 15. Since the main pressing plate 11 and the auxiliary pressing plate 16 are on the same horizontal line, they can simultaneously press and fix both ends of the plastic wrap when they move downward. The rubber pressing layer 12 can improve the firmness of fixing the plastic wrap. Then, the guide slide column 20 can be pulled by the support handle 23 to slide inside the knife holder cylinder 19. When the guide slide column 20 moves, it carries the knife 22 back and forth through the L-shaped frame 21, so that the knife 22 moves along the cutting groove 8, thereby achieving a neater and more precise cutting of the plastic wrap.
