[0002] PE stretch film is an industrial packaging film product with the characteristics of high tensile strength, large elongation, good self-adhesion and high transparency. It is often used for product packaging and protection, warehousing, transportation and other purposes. PE stretch film has high puncture resistance, tensile and tear resistance, and can play the role of protection, bundling, covering, etc. It can also prevent products from scattering or damage, facilitate long-distance transportation and storage, and improve work efficiency. However, the sizes of the stretch films used in the process of use are different, so it is difficult to install and use stretch films of different sizes on fixed equipment. It has certain limitations and is extremely inconvenient to use. Utility Model Content

[0003] The utility model aims to provide a PE protective film winding device which is easy to insert and position, so as to solve the problem in the background technology that the winding films are of different sizes and difficult to be installed inside the device.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a PE protective film winding device that is easy to snap into position, comprising a frame, the outer surface of one end of the frame is inclined, and a transport roller is fixedly installed on the outer surface of the inclined end of the frame, a drive motor is fixedly installed inside the frame, and the output end of the drive motor passes through the outer surface of the frame, a second cylinder is fixedly installed on the outer surface of one end of the frame away from the transport roller, and the output end of the second cylinder passes through the outer surface of the frame, a lifting motor is fixedly installed inside the frame, and the output end of the lifting motor passes through the outer surface of the frame, a sliding mechanism is arranged between the frame and the lifting motor, and the PE protective film can be conveniently installed through the sliding mechanism.

[0005] Preferably, a lower support frame is slidably installed on the outer surface of the frame, and a slider is fixedly installed on the side surface of the lower support frame, and a threaded rod is installed through the outer surface of the slider, the slider and the threaded rod are threadedly connected, and the threaded rod is rotatably installed inside the frame, the slider is slidably installed inside the frame, one end of the threaded rod is connected to the lifting motor, an upper bracket is slidably installed inside the frame, and the upper bracket and the lower support frame have the same upper and lower positions, and rotating plugs are rotatably installed on the outer surfaces of the lower support frame and the upper bracket, and the outer surfaces of the rotating plugs are inclined.

[0006] By adopting the above technical scheme, when installing the stretch film, the upper bracket can be lifted, and then the stretch film can be directly inserted into the rotating plug of the lower support frame, and the upper bracket can be lowered so that the rotating plug is inserted into the other end of the stretch film. The stretch film is automatically aligned along the inclined surface of the rotating plug through the dead weight of the upper bracket, so that the upper bracket and the lower support frame can automatically clamp and align the stretch film, and at the same time, the threaded rod can be driven to rotate by the rotation of the lifting motor, so that the slider can drive the lower support frame to move up and down to adjust the height to wrap the film, so as to be suitable for the installation and use of stretch films of different sizes.

[0007] Preferably, a pushing mechanism is provided between the driving motor and the frame, and the objects to be wrapped with the film are fixed by the pushing mechanism so that the objects will not fall due to the rapid rotation of the driving motor.

[0008] By adopting the above technical solution, the objects placed on the rotating tray can be clamped and fixed, so that when the objects are wrapped around the film, they will not fall out of the rotating tray due to the centrifugal force of the rotation.

[0009] Preferably, the pushing mechanism includes: a first cylinder, the first cylinder is fixedly mounted on one end of the frame close to the driving motor, and the driving motor and the first cylinder are concentrically designed, and the output end of the first cylinder passes through the outer surface of the frame, a pressing plate is rotatably mounted on the output end of the first cylinder, and the pressing plate and the driving motor are concentrically designed, a rotating tray is fixedly mounted on the output end of the driving motor, and the rotating tray is rotatably mounted on the outer surface of the frame.

[0010] By adopting the above technical solution, after placing the article on top of the rotating tray, the first cylinder can be started, and the pressing plate can be pushed out by starting the first cylinder, so that the pressing plate is pushed toward the article and cooperates with the rotating tray to clamp the article. The rotating tray and the pressing plate are driven to rotate in coordination with the rotation of the driving motor, so that the film is wrapped around the outer surface of the article.

[0012] By adopting the above technical scheme, the turning bolt is rotated to move forward and push the copper brake shoe. The turning bolt is prevented from rotating by the spring, and the copper brake shoe is close to the outer surface of the rotating plug. The friction between the rotating plug and the copper brake shoe prevents the wrapping film from rotating too fast and generating tension.

[0013] Preferably, an elastic sliding mechanism is provided at one end of the frame close to the second cylinder, so that the protective film will not be displaced during cutting to cause bevel cutting and uneven cutting of the film.

[0014] By adopting the above technical solution, the film will not be cut crooked or torn when the blade cuts the film, and the film can be easily pulled out for use when wrapping an object again later.

[0015] Preferably, the elastic sliding mechanism comprises: an elastic pressure plate, the elastic pressure plate is slidably mounted on a side of the frame close to the second cylinder, and a tool holder block is fixedly mounted on the output end of the second cylinder, and a blade is fixedly mounted on the side surface of the tool holder block, a roller is fixedly mounted on the outer surface of the frame, a fixing rod is fixedly mounted on the outer surface of the frame, and the outer surface of the fixing rod passes through the outer surface of the tool holder block, a cross bar (20) is fixedly mounted on the side surface of one end of the tool holder block close to the second cylinder, and the cross bar (20) is in contact with the side surface of the tool holder block, and an inclined surface is provided on the side surface of the tool holder block, and a guide rod is fixedly mounted on the outer surface of the frame.

[0016] By adopting the above technical solution, the film will pass through the roller and the elastic pressure plate, and pass through the guide rod and then be tied to the object. When the rotating tray rotates, it will drive the film to wrap around the outer surface of the object. When the wrapping is completed, the second cylinder is started to squeeze the knife holder block, so that the knife holder block slides along the direction of the roller, and the cross bar (20) moves along the inclined surface of the elastic pressure plate, pushing the elastic pressure plate out to cooperate with the roller to clamp the film. Then, as the knife holder block descends, the blade is driven to cut the film, so that the film will not be cut obliquely and torn and tilted, so that the second cylinder can clamp and cut the protective film when it descends, so that the protective wrapping film can be cut neatly.

[0017] Compared with the prior art, the utility model has the following beneficial effects: the PE protective film winding device which is easy to be inserted and positioned:

[0018] 1. When loading the protective film into the device, you need to lift the upper bracket first, so that the upper bracket can slide upward inside the frame, and then insert the protective film into the rotating plug of the lower support frame, and then put down the upper bracket, so that the rotating plug of the upper bracket is inserted into the other end of the protective film. Through the deadweight of the upper bracket and the inclined surface of the rotating plug, the protective film can be automatically fixed and aligned, so that protective films of different specifications can be conveniently installed inside the device for use;

[0019] 2. The pressing plate is pushed by the first cylinder so that the pressing plate cooperates with the rotating tray to clamp the articles to be coated. As the driving motor drives the rotating tray and the pressing plate to rotate, the articles are coated. When the protective film cannot be tightly wrapped around the outer surface of the article, the screw bolt can be adjusted so that the screw bolt can move forward on the lower support frame and push the copper brake shoe so that the copper brake shoe fits the outer surface of the rotating plug head, so as to adjust the friction between the rotating plug head and the copper brake shoe, so that the protective film is tightly wrapped around the outer surface of the article during coating, thereby improving the coating winding effect. At the same time, the clamping of the pressing plate and the rotating tray prevents the article from flying out due to the rotation of the rotating tray.

[0020] 3. When the lamination is completed, the second cylinder can be started. The second cylinder pushes out the tool holder block to slide along the direction of the fixed rod. At the same time, the cross bar (20) moves with the tool holder block, so that the cross bar (20) slides down along the inclined surface of the elastic pressure plate to push the elastic pressure plate out, so that the elastic pressure plate is close to the roller to clamp the protective film. At the same time, the blade moves with the tool holder block to vertically cut the taut protective film between the roller and the guide rod, so that the protective film will not be cut obliquely and torn, and it is convenient to take the protective film from between the roller and the elastic pressure plate when laminating next time.
