Description

Technical Field

[0001] This utility model relates to the field of electronic protective film processing equipment, and more specifically, to a winding device for the production of protective films. Background Technology

[0002] Protective film is a thin, soft, transparent sheet made of plastic, adhesive, rubber, or other materials. It is widely used in the electronics, machinery, and printing industries. After processing, the protective film needs to be wound up. Existing winding devices achieve the purpose of shock absorption, dust removal, and fixing of the protective film during the winding process by setting up lateral fans and multiple shock-absorbing structures. However, during the winding process, the protective film may also carry static electricity, and if the air is only blown from the side, it may cause the moving protective film to sway from side to side, which is not conducive to the flatness of the winding.

[0003] Regarding the aforementioned issues, specifically the technical problems of static electricity on the protective film and the side-blowing causing the protective film to sway left and right, extensive searches revealed patent CN218261042U, which proposes a winding device for protective film production. This device includes, from left to right, a pressure roller assembly, an atomizer, a blowing assembly, a guide roller, and a winding roller mounted on an operating table. The pressure roller assembly, atomizer, guide roller, and winding roller are each mounted on four pairs of mounting brackets spanning both sides of the table. The pressure roller assembly includes two tangential pressure rollers positioned vertically. There are two atomizers with their outlets facing the center of the table. The winding rollers are mounted on... The device is driven to rotate by a motor on one side. The blower assembly consists of a bracket spanning both sides of the tabletop and two fan modules mounted vertically on the bracket. Each fan module includes a module with an arc-shaped edge on the left and a straight edge on the right. The area where the arc-shaped edge of the module is located has several mounting positions, each of which is where a fan is embedded. The modules have cylinders on both sides, which are inserted into through holes on the bracket. The sides of the cylinders also have radial positioning holes. The top of the bracket has pin holes perpendicular to the tabletop, and the fan modules are positioned by inserting positioning pins into the pin holes and positioning holes. However, the technical solution provided by this patent has the following problems:

[0004] (1) The sprayers are arranged on both sides of the operating table. When the mist is sprayed out, the central part of the protective film receives less spray and the bottom of the protective film cannot be sprayed, resulting in incomplete removal of static electricity.

[0005] (2) When winding up the protective film, it is usually necessary to maintain a certain tension to ensure the normal transport of the protective film. When the tension decreases, that is, the protective film is in a loose state, the fabric is prone to slipping, jamming and other problems, which seriously affect the production progress. However, the above-mentioned device cannot maintain the tension.

[0006] This invention can evenly spray mist onto the protective film and maintain the tension of the protective film. Utility Model Content

[0017] Beneficial effects:

[0018] 1. By incorporating a spray assembly, the protective film is evenly sprayed with mist, and the liquid generated after the mist cools on the base is prevented from forming excessive amounts of liquid. The spray assembly includes: an atomizing box, an air supply pipe, a regulating valve, a drain valve, an atomizing nozzle, and a water storage tank. The atomizing box transports the mist and reduces its dispersion. The air supply pipe delivers the mist to the atomizing box. The regulating valve adjusts the mist size. The atomizing nozzle evenly sprays the mist onto the protective film. The water storage tank stores the liquid generated after the mist cools. The drain valve removes the liquid from the water storage tank.

[0019] 2. By incorporating a tension-maintaining component, the protective film's tension is maintained. This component includes: a first support frame, a first rotating roller, a first connecting shaft, a limiting rod, a second support frame, a second connecting shaft, a second rotating roller, a limiting slider, a third connecting shaft, a shelf, and a counterweight. The limiting rod and the grooves on the second support frame restrict the displacement of the second connecting shaft. The second connecting shaft drives the second rotating roller, which applies tension to the protective film. The counterweight on the shelf maintains the protective film's tension.

[0020] 3. By incorporating baffles, bolts, and slots, the baffles effectively limit the counterweight, preventing excessive slippage and derailment during displacement, thus enhancing the overall structural safety. The bolts and slots provide a reliable fixing method. The diagonally distributed bolts abut against the slots evenly distribute the force, enhancing the stability of the connection and preventing loosening or displacement of components under stress. Simultaneously, the positioning effect achieved by increasing sliding friction ensures that the components remain stable under different working conditions, effectively improving the overall structural load-bearing capacity and durability.

[0027] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0028] Please see Figure 1-5In this embodiment of the present invention, a winding device for producing protective film includes: a base 1, with a film pressing roller group 2, a spraying assembly 3, a blowing assembly 4 and a tension holding assembly 5 arranged sequentially from left to right on the upper end of the base 1, and a winding roller assembly 6 arranged at the center of the right end of the base 1.

[0029] In this embodiment of the invention, the spray assembly 3 includes: an atomizing box 301, an air supply pipe 302, a regulating valve 303, a drain valve 304, atomizing nozzles 305, and a water storage tank 306; two sets of air supply pipes 302 are symmetrically arranged and fixedly connected to the center of the front and rear sides of the upper end of the base 1, and an atomizing box 301 is fixedly connected to the center of the two sets of air supply pipes 302; several evenly arranged atomizing nozzles 305 are fixedly connected to the upper and lower ends of the inner side of the atomizing box 301, and the atomizing nozzles 305 are symmetrically arranged in the mist... Inside the atomizing box 301, at both the upper and lower ends, a water storage tank 306 is fixedly connected to the bottom of the atomizing box 301, and a drain valve 304 is fixedly connected to the bottom of the water storage tank 306. A regulating valve 303 is arranged on the air supply pipe 302 at the front end of the base 1. Through the atomizing box 301, the atomizing gas is transported and its dispersion is reduced. Through the air supply pipe 302, the atomizing gas is delivered to the atomizing box 301. Through the regulating valve 303, the atomizing nozzle 30... 5. To achieve the effect of evenly spraying mist onto the protective film, the water tank 306 stores the liquid after the mist cools down, and the drain valve 304 drains the liquid from the water tank 306. In use, the mist is transported to the atomizing box 301 through the air supply pipe 302. The mist is then sprayed out from the atomizing nozzles 305 evenly arranged at both ends of the atomizing box 301, so that the mist is evenly sprayed onto the protective film, thereby removing static electricity from the protective film. The regulating valve 303 arranged on the air supply pipe 302 is rotated to adjust the spray size to suit the needs of different protective films. The atomizing box 301 has a semi-enclosed structure, so that most of the mist is retained in the atomizing box 301, which further improves the efficiency of the mist in removing static electricity and also avoids a large amount of liquid after the mist cools down on the base 1. The water accumulated after the mist cools down will flow to the water tank 306. Rotating the drain valve 304 allows the water accumulated in the water tank 306 to flow out from the bottom of the water tank 306.

[0030] In this embodiment of the utility model, a plurality of drainage grooves are provided at the bottom of the atomizing box 301. By providing drainage grooves at the bottom of the atomizing box 301, the effect of guiding the cooled liquid of the mist to the water storage tank 306 is achieved.

[0031] In this embodiment of the utility model, a square opening is provided at the center of both the front and rear ends of the atomizing box 301. By providing a square opening at the center of both the front and rear ends of the atomizing box 301, the protective film can pass through the spray assembly 3 while maintaining the atomizing box 301's ability to reduce the dispersion of mist.

[0032] In this embodiment of the utility model, the tension holding assembly 5 includes: a first support frame 501, a first rotating roller 502, a first connecting shaft 503, a limiting rod 504, a second support frame 505, a second connecting shaft 506, a second rotating roller 507, a limiting slider 508, a third connecting shaft 509, a container rack 510, and a counterweight 511. Two sets of the first support frame 501, limiting rod 504, second support frame 505, limiting slider 508, third connecting shaft 509, container rack 510, and counterweight 511 are symmetrically arranged on both sides of the base 1. A first support frame 501 is fixedly connected to the upper right side. A first connecting shaft 503 is movably connected to the upper end of the first support frame 501. A first rotating roller 502 is sleeved on the first connecting shaft 503. The first rotating roller 502 is located in the center of the two first support frames 501. A limit rod 504 is movably connected to the left end of the first connecting shaft 503. A limit slider 508 is sleeved on the limit rod 504. A second support frame 505 is fixedly connected to the upper left side of the base 1. A sliding groove is opened in the center of both the second support frame 505 and the limit rod 504. A second connecting shaft 506 is movably connected to the slide rail 4. A second rotating roller 507 is sleeved on the second connecting shaft 506. The second rotating roller 507 is located in the center of the two limiting sliders 508. A third connecting shaft 509 is movably connected to the bottom end of the limiting rod 504. A container rack 510 is movably connected to the third connecting shaft 509. A counterweight 511 is arranged on the container rack 510. The slide rails on the limiting rod 504 and the second support frame 505 limit the displacement of the second connecting shaft 506. The second connecting shaft 506 drives the second rotating roller 507. The effect of the movement is achieved by applying tension to the protective film through the second rotating roller 507. The effect of maintaining the tension of the protective film is achieved by placing a counterweight 511 on the shelf 510. In use, first place the counterweight 511 on the shelf 510, so that the shelf 510 drives the second connecting shaft 506 to move to the left along the slide groove of the second support frame 505. The second connecting shaft 506 drives the second rotating roller 507 to move to the left, so that the second rotating roller 507 presses against the protective film, applying tension to the protective film, thereby maintaining the tension of the protective film.

[0033] In this embodiment of the utility model, a cylindrical protrusion is arranged in the center of the right end of the limiting slider 508, and a circular hole is opened in the center of the limiting slider 508. The circular hole passes through the left end of the limiting slider 508 to the center of the cylindrical protrusion. The circular hole fits with the second connecting shaft 506. By opening a hole in the limiting slider 508, the left and right displacement of the second connecting shaft 506 is restricted and the wear of the second connecting shaft 506 is reduced.

[0034] In this embodiment of the invention, one to four counterweights 511 can be added to the shelf 510. Baffles 512 are fixedly installed at both ends of the shelf 510, with the left baffle 512 being closed and the right baffle 512 being semi-closed. By changing the number of counterweights 511 on the shelf 510, the tension applied to the protective film by the second roller 507 can be adjusted. Different protective film materials have different hardness, thickness, and weight. When using a protective film with high hardness, thickness, and weight, four counterweights 511 are placed to apply more tension to the protective film. When the protective film has low hardness, thinness, and light weight, a counterweight 511 is placed to apply a smaller tension to the protective film, thereby achieving a better tension effect. At the same time, the baffle 512 at the rear end of the shelf 510 completely closes the left end of the shelf 510, preventing the counterweight 511 from slipping out from the left end. The baffle 512 at the right end is semi-closed, allowing the counterweight 511 to be inserted into the shelf 510 from above the baffle 512, and the bottom is blocked by the baffle 512, preventing it from slipping out from the right end of the shelf 510.

[0035] In this embodiment of the invention, the second support frame 505 has slots 513 on both the upper and lower sides of its outer end face, and bolts 514 are threaded onto both the upper and lower sides of the outer side of the limiting slider 508. Two bolts 514 are diagonally distributed, passing through the limiting slider 508 and abutting against the slots 513. When it is necessary to place the counterweight 511 inside the shelf 510 to allow the second connecting shaft 506 to move to the left along the sliding groove of the second support frame 505, after placing the counterweight 511 into the shelf 510, the bolts 514 are then... 4. Once all the bolts are unscrewed, under the influence of the counterweight 511, the second connecting shaft 506 moves to the left along the slide groove of the second support frame 505. After moving to the appropriate position, the bolts 514 are screwed back in. The bolts 514 pass through the limiting slider 508 and are inserted into the slot 513, thereby increasing the sliding friction of the second connecting shaft 506. This makes the sliding force provided by the counterweight 511 less than the clamping force provided by the bolts 514, thus fixing the position and preventing the second connecting shaft 506 from automatically moving to the left due to gravity.

[0036] Working principle: During use, the mist is transported to the atomizing box 301 through the air supply pipe 302. The mist is then sprayed out from the atomizing nozzles 305 evenly arranged at both ends of the atomizing box 301, so that the mist is evenly sprayed on the protective film, thereby removing static electricity from the protective film. By rotating the regulating valve 303 arranged on the air supply pipe 302, the spray size is adjusted to suit the needs of different protective films. The atomizing box 301 has a semi-enclosed structure, which allows most of the mist to remain inside the atomizing box 301, further improving the efficiency of static electricity removal by the mist, and also preventing a large amount of liquid from cooling the mist from appearing on the base 1. A drainage groove is provided at the bottom of the cooling box 301. The liquid after the mist is cooled will be guided to the water storage tank 306 by the drainage groove. Turning the drain valve 304 allows the water in the water storage tank 306 to flow out from the bottom of the water storage tank 306. The counterweight 511 is placed on the shelf 510, causing the shelf 510 to drive the second connecting shaft 506 to move to the left along the slide groove of the second support frame 505. The second connecting shaft 506 drives the second rotating roller 507 to move to the left, causing the second rotating roller 507 to press against the protective film, applying tension to the protective film and thus maintaining the tension of the protective film. Different protective film materials have different hardness, thickness, and weight. When the hardness is... When the protective film is thick, heavy, and has high strength, four counterweights 511 are placed to apply greater tension to the protective film. When the protective film has low hardness, thinness, and light weight, one counterweight 511 is placed to apply less tension to the protective film, thus achieving a better tensioning effect. After the counterweights 511 are placed in the holder 510, all bolts 514 are unscrewed. Under the influence of the counterweights 511, the second connecting shaft 506 moves to the left along the slide groove of the second support frame 505. After moving to the appropriate position, the bolts 514 are screwed back in, and the bolts 514 pass through the limit slider 508 and are inserted into the slot 513. This increases the sliding friction of the second connecting shaft 506, making the sliding force provided by the counterweight 511 less than the clamping force provided by the bolt 514, thereby fixing the position and preventing the second connecting shaft 506 from automatically shifting to the left due to gravity. At the same time, the baffle 512 at the rear end of the shelf 510 completely closes the left end of the shelf 510, preventing the counterweight 511 from sliding out from the left end. The baffle 512 at the right end is semi-closed, allowing the counterweight 511 to be placed inside the shelf 510 from above the baffle 512, and the bottom is blocked by the baffle 512, preventing it from sliding out from the right end of the shelf 510.
