Description

Technical Field

[0001] This utility model relates to the technical field of protective film winding mechanism, specifically a PE protective film winding mechanism. Background Technology

[0002] PE protective film is the simplest structural polymer organic compound and the most widely used polymer material in the world today. PE protective film uses a special polyethylene plastic film as its base material and is classified into high-density polyethylene, medium-density polyethylene, and low-density polyethylene protective films according to their density.

[0003] Because PE protective film is applicable to many industries such as building materials, electronics, food, and chemicals, PE protective film wrapping machines are often used to wrap items with PE protective film to provide protection functions such as scratch resistance, moisture resistance, and dust resistance, or to wrap and store PE protective film.

[0004] Existing patent document CN221216427U discloses a PE protective film winding device, including a base, a bracket mounted parallel to the upper part of the base, a stepper motor mounted on the outer side of one of the brackets, a main gear mounted at the end of the output shaft of the stepper motor, the main gear meshing with a secondary gear, a square groove horizontally formed on the upper part of the opposite side of the bracket, a movable plate slidably disposed between the inner sides of the square groove, and a scraper mounted on the side of the movable plate near the take-up shaft. This invention slowly winds the PE protective film to the outside of the take-up shaft during the winding process, while the scraper contacts the PE protective film and adheres it to the outside of the take-up shaft, preventing air bubbles. As the thickness of the PE protective film outside the take-up shaft increases, the movable plate is pushed to the other side of the square groove to accommodate the continuously thickening PE protective film.

[0005] Although the device has many beneficial effects, it still has the following problems: after the film roll becomes heavier, manual extraction requires overcoming axial friction; the installation groove has no self-locking function; there is axial movement during high-speed rotation; secondly, the scraper only relies on the film thickness to generate contact pressure, which leads to a decrease in the air bubble removal rate. Utility Model Content

[0006] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0007] 1. Technical problems to be solved:

[0008] To address the aforementioned problems of difficult loading and unloading of the winding roller and incomplete removal of air bubbles, this utility model is proposed.

[0009] Therefore, the purpose of this utility model is to provide a PE protective film winding mechanism, which adopts a transmission system composed of a lead screw and a bevel gear. The lead screw converts the rotational motion into the vertical displacement of the lifting plate. The inclined plate realizes the lifting force amplification effect of the winding roller. The linkage limit of the rotating retaining ring effectively reduces the radial constraint tolerance. At the same time, by adding a pre-compression spring group to the side wall of the scraper bracket, an adjustable bubble removal structure is formed. The spring group structure realizes the scraper's adaptive compensation for film thickness deviation, effectively improving the bubble removal rate.

[0010] 2. Technical Solution:

[0034] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0035] This utility model provides an overall structural schematic diagram of one embodiment of a PE protective film winding mechanism, including:

[0036] Please see Figures 1-5 This embodiment of a PE protective film wrapping mechanism includes a workbench 100. Multiple vertical placement plates are welded to the top of the workbench 100. Rollers 110 are rotatably connected to the side walls of the vertical placement plates. A removal assembly 200 is provided on the top of the workbench 100. The removal assembly 200 includes a housing 210, a first lead screw 220, a second lead screw 231, a lifting plate 240, and an inclined plate 241. Multiple connecting plates are welded to the top of the housing 210. A scraping assembly 300 is provided on the side wall of the connecting plate. The scraping assembly 300 includes a scraper and a spring 320. A fixing assembly 400 is provided on the top of the side wall of the connecting plate. The fixing assembly 400 includes a retaining ring 420 and a slider 430.

[0037] It is worth noting that, in order to facilitate the removal of component 200, specifically, a lead screw 220 is inserted into the side wall of the outer casing 210. The lead screw 220 passes through the outer casing 210 and has a handle welded on it. By rotating the lead screw 220, multiple main bevel gears 221 are sleeved on the outer circumference of the lead screw 220. A secondary bevel gear 230 is vertically meshed on the outer circumference of the main bevel gears 221. A second lead screw 231 is welded to the top of the secondary bevel gear 230. A lifting plate 240 is sleeved on the outer circumference of the second lead screw 231 to facilitate the control of the lifting of the inclined plate 241. The inclined plate 241 is welded to the top of the lifting plate 240. The inclined plate 241 uses an inclined structure to remove the winding roller 120 from the mounting groove.

[0038] Next, in order to facilitate the removal of air bubbles by the scraping component 300, specifically, the scraping component 300 includes a bracket 310, with multiple springs 320 welded to the side wall of the bracket 310 to facilitate the scraper 330 to adaptively and closely adhere to the outer circumference of the winding roller 120 to wrap the film surface. The scraper 330 is welded to the top of the side wall of the bracket 310 for removing air bubbles.

[0039] Meanwhile, for convenience, specifically, the fixing component 400 includes a mounting plate 410, a rotating shaft 411 is inserted into the side of the mounting plate 410, and a retaining ring 420 is sleeved on the outer circumference of the rotating shaft 411 for limiting and fixing the winding roller 120. The retaining ring 420 has an insertion hole 421 on its side wall for convenient limiting of the retaining ring 420. The connecting plate has a T-shaped slide groove on its side wall, and a slider 430 is slidably connected inside the T-shaped slide groove. The top and bottom of the slider 430 are integrally formed with limiting blocks that match the internal structure shape of the T-shaped slide groove to prevent the slider 430 from moving out of the T-shaped slide groove.

[0040] Furthermore, to facilitate the rotation of the winding roller 120, a support plate 211 is welded to the top of the side wall of the outer casing 210. A motor 212 is fixedly connected to the top of the support plate 211 by screws. A button for electrically connecting the motor 212 is provided on the side wall of the motor 212. A main gear 213 is sleeved on the output end of the motor 212. A driven gear 214 meshes with the outer circumference of the main gear 213. The winding roller 120 is welded to the side wall of the driven gear 214. A limit block is welded to the other end of the winding roller 120 for lateral limiting of the winding roller 120.

[0041] It is worth noting that, in order to facilitate the lateral movement of the bracket 310, specifically, a rotating shaft 311 is welded to the side wall of the bracket 310, and a rotating wheel 312 is sleeved on the outer circumference of the rotating shaft 311. When the scraper 330 is pushed laterally due to the increase in the thickness of the PE protective film, the rotating wheel 312 rotates and rolls in coordination with the lateral movement of the bracket 310. A protective strip is embedded on the top of the scraper 330. The protective strip is a rubber strip to prevent the scraper 330 from scratching the film.

[0042] Finally, to facilitate the locking of the retaining ring 420, specifically, the side wall of the slider 430 is integrally formed with an insert block to facilitate locking the retaining ring 420. The shape and size of the insert block match the shape and size of the insertion hole 421. When the mechanism operates and vibrates, the retaining ring 420 first vertically limits the winding roller 120 to prevent it from disengaging. The insert block, inserted into the insertion hole 421, locks the retaining ring 420. At the same time, due to the internal structure of the T-shaped slide groove and the two limiting blocks at the top and bottom of the slider 430, the contact area between the slider 430 and the T-shaped slide groove is increased, effectively increasing the friction. The slider 430, in conjunction with the T-shaped slide groove, achieves a certain degree of limiting self-locking.

[0043] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0044] Combination Figures 1-5 The specific usage process of the PE protective film wrapping mechanism of this embodiment is as follows:

[0045] 1: After the film to be wrapped and stored is flattened between the two rollers 110 at the top of the workbench 100, one end of it is wrapped around the wrapping roller 120. Then, press the button to turn on the motor 212. The motor 212 drives the main gear 213 to rotate. Then, the main gear 213 drives the driven gear 214 to rotate. The driven gear 214 drives the wrapping roller 120 to rotate.

[0046] 2: Rotate the retaining ring 420 so that its internal U-shaped structure is tightly attached to the winding roller 120. Then slide the slider 430 laterally so that the insert block on the side wall of the slider 430 is inserted into the insertion hole 421 to limit and fix the retaining ring 420. At this time, the retaining ring 420 vertically limits one end of the winding roller 120.

[0047] 3. During the winding and storage operation, the scraper 330 adheres closely to the side wall of the film and scrapes away internal air bubbles. At the same time, the spring 320 continuously pushes the scraper 330 to keep it close to the side wall of the film. After the winding and storage operation is completed, the sliding slider 430 releases the lock on the retaining ring 420. Then, the retaining ring 420 is rotated to contact the limit of the winding roller 120. The handle is rotated to rotate the lead screw 220. The lead screw 220 drives the main bevel gear 221 to rotate. The main bevel gear 221 drives the driven bevel gear 230 to rotate. Then, the driven bevel gear 230 drives the lead screw 231 to rotate. The rotation of the lead screw 231 drives the lifting plate 240 to rise and move. The lifting plate 240 drives the inclined plate 241 to rise vertically, so that the winding roller 120 is pushed out of the mounting groove of the connecting plate.

[0048] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
