Technical Field

[0001] The utility model belongs to the technical field of winding devices, and particularly relates to a winding device for plastic sealing films. Background Technique

[0002] A plastic sealing film is a kind of plastic film, usually used for packaging, protecting and displaying items such as papers, photos, documents, etc. It is divided into various types, such as heat-sealing plastic films and cold-sealing plastic films. After the plastic sealing film is produced, it needs to be wound by a winding device for winding, so as to facilitate transportation and storage.

[0003] When the winding device winds, the reel needs to be sleeved on the roller shaft. To prevent relative rotation between the roller shaft and the reel, an interference fit is required between the reel and the roller shaft. This kind of fit will cause it to be inconvenient to remove the reel from the roller shaft after winding is completed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a winding device for plastic sealing films, which can directly push the plastic sealing film roll off the winding structure through a pushing-off structure, facilitating the collection of the plastic sealing film roll, so as to solve the problems put forward in the above background technique.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the purpose and advantages of the present utility model clearer, the following further describes the present utility model in detail with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0020] As Figure 1As shown in the figure, a winding device for a plastic sealing film includes a base 1 and a vertical support frame 2. The vertical support frame 2 is fixedly connected to one side of the base 1. A winding structure 3 is arranged at the top of the vertical support frame 2, and a pushing structure 4 for pushing the plastic sealing film roll away from the winding structure 3 is arranged at the bottom of the vertical support frame 2. The top end of the base 1 is fixedly connected with a support structure 5, and the top end of the support structure 5 is in contact connection with one end of the winding structure 3.

[0021] According to the above structure, when in use, the paper tube is sleeved on the winding structure 3, and the winding structure 3 drives the paper tube to rotate to wind the plastic sealing film. When the winding is completed, the plastic sealing film roll is directly pushed down from the winding structure 3 through the pushing structure 4, which is convenient for collecting the plastic sealing film roll. The support structure 5 can support the end of the winding structure 3 during winding, improving stability.

[0022] As Figure 1 shown in the figure, the winding structure 3 includes a cylinder 31 embedded at the top of the vertical support frame 2. A winding roller 32 is rotatably connected inside the cylinder 31 through a bearing. One side of the vertical support frame 2 is fixedly connected with a winding motor 33, and the output shaft of the winding motor 33 is fixedly connected with one end of the winding roller 32. An annular groove 34 is arranged at one end of the side wall of the winding roller 32.

[0023] According to the above structure, during winding, the paper tube is sleeved on the winding roller 32, and the winding motor 33 drives the winding roller 32 to rotate, thereby driving the paper tube to rotate to wind the plastic sealing film.

[0024] As Figure 2 and 3 shown in the figure, the pushing structure 4 includes a track 41 fixedly connected to the bottom of the vertical support frame 2. A lead screw 42 is rotatably connected inside the track 41. A positive and negative motor 43 is arranged on one side of the vertical support frame 2, and the output shaft of the positive and negative motor 43 is fixedly connected with one end of the lead screw 42. A slider 44 is slidably connected inside the track 41, and the lead screw 42 is in threaded transmission connection with the slider 44. The top end of the slider 44 is fixedly connected with a connecting plate 45, and the top end of the connecting plate 45 is fixedly connected with a pushing plate 46.

[0025] According to the above structure, when the winding is completed, the positive and negative motor 43 drives the lead screw 42 to rotate clockwise. Through the transmission of the slider 44, the connecting plate 45 is driven to move to the right, and then the pushing plate 46 is driven to move to the right to push the plastic sealing film roll to move to the right and separate from the winding roller 32.

[0026] As Figure 4 shown in the figure, the support structure 5 includes a base plate 51. The bottom end of the base plate 51 is fixedly connected with a servo telescopic rod 52. An installation frame 53 is arranged above the base plate 51. A spring 54 is fixedly connected between the base plate 51 and the installation frame 53. Inside the installation frame 53, rollers 55 are symmetrically rotatably connected. Four corner edges of the top end of the base plate 51 are fixedly connected with sliding columns 56, and all four sliding columns 56 penetrate through the installation frame 53.

[0027] According to the above structure, when winding, the substrate 51 is elongated so that the side walls of the two rollers 55 are in contact with the side walls of the annular groove 34, and the servo telescopic rod 52 is elongated by a certain length to compress the spring 54, thereby increasing the supporting force of the roller 55 on the end of the winding roller 32. Moreover, the spring 54 can provide buffering to avoid damage to parts caused by excessive extrusion force between the winding roller 32 and the roller 55 due to hard contact between the roller 55 and the winding roller 32. The setting of the sliding column 56 can improve the stability of the up and down movement of the mounting bracket 53 and prevent the roller 55 from not corresponding to the annular groove 34.

[0028] The working principle of the present utility model is as follows: When winding, the paper tube is sleeved on the winding roller 32, and the winding roller 32 is driven to rotate by the winding motor 33, thereby driving the paper tube to rotate to wind the plastic sealing film. When the winding is completed, the lead screw 42 is driven to rotate clockwise by the forward and reverse motor 43, and the connecting plate 45 is driven to move to the right through the transmission of the slider 44, and then the push plate 46 is driven to move to the right to push the plastic sealing film roll to move to the right and separate from the winding roller 32. When winding, the substrate 51 is elongated so that the side walls of the two rollers 55 are in contact with the side walls of the annular groove 34, and the servo telescopic rod 52 is elongated by a certain length to compress the spring 54, thereby increasing the supporting force of the roller 55 on the end of the winding roller 32. Moreover, the spring 54 can provide buffering to avoid damage to parts caused by excessive extrusion force between the winding roller 32 and the roller 55 due to hard contact between the roller 55 and the winding roller 32. The setting of the sliding column 56 can improve the stability of the up and down movement of the mounting bracket 53 and prevent the roller 55 from not corresponding to the annular groove 34.

[0029] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special instructions and limitations.
