[0002] Plastic film refers to film made of polyvinyl chloride, polyethylene, polypropylene and other resins. The characteristics of plastic film include wear resistance, water resistance, chemical corrosion resistance, recyclability, easy processing and molding. It is mainly used for packaging and coating layers, and is widely used in food, medicine, chemical and other fields. After the production of plastic film, it is necessary to use the relevant winding roller to roll up the plastic film for easy storage and transportation.
[0003] At present, the plastic film winding roller is driven by a motor to rotate. When the motor stops working, the winding roller is easy to reverse under the action of external force, causing the film to become wrinkled and loose. After the film is rolled up, the plastic film needs to be cut manually, which not only increases people's workload but also reduces work efficiency. Utility Model Content

Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0026] Embodiment 1, as Figure 1-Figure 5 As shown, the utility model provides a plastic film winding roller, comprising a winding mechanism 1, and a flattening mechanism 2 is fixedly installed on the top of the winding mechanism 1;
[0027] The winding mechanism 1 includes a bottom plate 101, a group of ear blocks 102 are fixedly installed on the top of the bottom plate 101, a group of holes 103 are opened on the outer wall of the ear blocks 102, a motor 104 is fixedly installed on one side of the outer wall of one of the ear blocks 102, a winding roller 105 is fixedly installed on the output end of the motor 104, and the outer wall of the winding roller 105 is movably inserted between the inner walls of the holes 103, a fixing rod 106 is fixedly installed on one side of the outer wall of another ear block 102, and the fixing rod 106 is fixedly installed on the outer wall of the other ear block 102. 6 is movably sleeved with a pawl 107, the outer wall of the pawl 107 is meshed with a ratchet 108, and one side of the outer wall of the ratchet 108 is fixedly connected to one side of the outer wall of the winding roller 105, a group of telescopic rods 109 are fixedly installed on the top of the bottom plate 101, a guide rail 110 is fixedly installed between the telescopic ends of the group of telescopic rods 109, a slide groove 111 is opened on the top of the guide rail 110, and an electric slider 112 is movably embedded in the inner wall of the slide groove 111, and a cutter 113 is fixedly installed on the top of the electric slider 112.
[0028] The effect achieved by the entire embodiment 1 is that after the motor 104 is started, it will drive the winding roller 105 to rotate, and the plastic film will be rolled up, which will drive the ratchet 108 to rotate and continuously lift the pawl 107. When the winding is completed and the motor 104 is turned off, if the winding roller 105 reverses, the pawl 107 will hold the ratchet 108 to prevent it from rotating, thereby preventing the winding roller 105 from reversing and preventing the film from wrinkling and loosening, thereby improving the winding effect. After the winding is completed, the two telescopic rods 109 will drive the guide rail 110 to rise, so that the cutter 113 is flush with the plastic film, and then the electric slider 112 will drive the cutter 113 to cut the plastic film. The device can reduce workload and improve production efficiency.
[0029] Embodiment 2, as Figure 2-Figure 5 As shown, the flattening mechanism 2 includes a fixed frame 201, a hole 202 is opened on the top of the fixed frame 201, a cylinder 203 is fixedly installed on the top of the fixed frame 201, a bracket 204 is fixedly installed on the output end of the cylinder 203, and the outer wall of the bracket 204 is movably inserted in the inside of the hole 202, a shell 205 is fixedly installed on the bottom of the bracket 204, a group of holes 3 206 is opened on the outer wall of the shell 205, an upper squeezing roller 207 is movably inserted between the inner walls of the group of holes 3 206, a group of holes 4 208 is opened on the outer wall of the fixed frame 201, a lower squeezing roller 209 is movably inserted between the inner walls of the group of holes 4 208, and the top of the bottom plate 101 is fixedly connected to the bottom of the fixed frame 201.
[0030] The effect achieved by the entire embodiment 2 is that before winding, the plastic film needs to be placed on the lower squeezing roller 209. When winding, the cylinder 203 is started to drive the upper squeezing roller 207 to descend through the bracket 204 and the shell 205, and clamp the plastic film together with the lower squeezing roller 209. When the plastic film is wound, the upper squeezing roller 207 and the lower squeezing roller 209 will be driven to rotate together to flatten the plastic film, avoid the formation of wrinkles during the winding process, improve the winding efficiency, and prevent the plastic film from being stuck in the equipment and causing equipment failure.
[0031] Working principle: When it is necessary to roll up the plastic film, the plastic film only needs to be passed through the fixed frame 201 and wound around the winding roller 105, and then the equipment is started. The cylinder 203 is started to make the bracket 204 descend. When the bracket 204 descends, the upper squeezing roller 207 is driven to descend through the shell 205, and the plastic film is pushed downward and contacts the lower squeezing roller 209. After the motor 104 is started, it drives the winding roller 105 to rotate and roll up the plastic film. At this time, the upper squeezing roller 207 and the lower squeezing roller 209 will rotate together to flatten the plastic film and then roll it up. When the winding roller When 105 rotates, it will drive the ratchet 108 to rotate in the same direction and continuously lift the pawl 107. When the winding is completed, the motor 104 is turned off. At this time, the winding roller 105 may reverse under the action of external force. When the winding roller 105 reverses, it will drive the ratchet 108 to rotate. At this time, the pawl 107 will push the top of the ratchet 108, making the winding roller 105 unable to rotate. After the winding is completed, the two telescopic rods 109 will drive the guide rail 110 to rise, so that the cutter 113 is flush with the plastic film, and then the electric slider 112 will drive the cutter 113 to move to cut the plastic film.
[0032] Among them, the motor 104, the telescopic rod 104, the electric slider 112, and the cylinder 203 are all existing technologies, and their components and operating principles are all public technologies, and no further explanation is given here.
[0033] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
