Description

Technical Field

[0001] The utility model belongs to the technical field of acrylic protective films, and in particular relates to a winding device for producing acrylic protective films. Background Art

[0002] Acrylic, chemically known as polymethyl methacrylate, is an important plastic polymer material that was developed earlier. It has good transparency, chemical stability and weather resistance, is easy to dye, easy to process, and has a beautiful appearance. Therefore, it is favored by the new material industry and is also famous in the field of protective films. Acrylic has high transparency, soft light, and clear vision. Acrylic colored with dyes has a good color development effect and has a transmittance comparable to that of glass, but its density is only half that of glass. In addition, it is not as fragile as glass. Even if it is damaged, it will not form sharp fragments like glass, so acrylic glue is an ideal material for protective films of electronic products. In terms of processing, the characteristics of acrylic glue are also particularly good. Acrylic has good weather resistance, high surface hardness and surface gloss, and good high temperature performance. It can be thermoformed or machined. The wear resistance of acrylic is close to that of aluminum, it has good stability, and is resistant to corrosion from a variety of chemicals, so it is also very conducive to mixing with other chemical substances during processing. When producing acrylic protective film, the produced acrylic protective film is often rolled up at the end.

[0003] For example, the Chinese patent with publication number CN211003756U discloses a winding device for producing acrylic protective film. The winding device for producing acrylic protective film includes a base; three brackets; rollers; a lower bracket, and the lower bracket is installed on the top surface of the base; an upper bracket; a transmission mechanism; a support frame; a rotating shaft; a cutting mechanism; a fixing mechanism, and the fixing mechanism includes a first slider, a first cavity, a vertical rod, a second cavity, a second slider, a fixed shaft, an L-shaped rod and a limit rod, the first cavity is provided inside the rotating shaft, the vertical rod is fixed to the bottom surface of the first slider, the second slider is slidably connected with the second cavity, and the second slider is fixed to the bottom surface of the vertical rod, the two fixed shafts are fixed on the inner side wall of the second slider, and one end of the two L-shaped rods is rotatably connected with the fixed shaft; a winding drum. The winding device for producing acrylic protective film provided by the utility model has the function of quickly replacing the winding drum.

[0004] This patent has some disadvantages when used, such as: the device in this patent cannot adaptively adjust the winding roller according to the protective film of different widths. When the protective film is rolled up, due to the fixed width of the rolling roller, the protective film with a shorter width is prone to deflection on the winding roller. In addition, the winding device cannot remove wrinkles and dust when the protective film is rolled up, so the rolled protective film roll is prone to contain wrinkles and dust, which greatly affects the quality. In view of this, we propose a winding device for acrylic protective film production. Utility Model Content

[0043] Embodiment 1:

[0044] See also Figure 1 - Figure 5 As shown, this embodiment provides a winding device for producing acrylic protective film, comprising:

[0045] A base 1, a first support arm 2 and a second support arm 3 are respectively fixed on the upper surface of the base 1 and near both ends, a winding roller 4 is rotatably installed on the inner side of the first support arm 2, a motor 5 is installed on the outer side of the first support arm 2, and the output device of the motor 5 passes through the first support arm 2 and is coaxially connected to the winding roller 4, and the other end of the winding roller 4 is slidably connected to a side plate 6;

[0046] An adjusting component, which is located on the second supporting arm 3 and is used to adjust the position of the side plate 6 on the winding roller 4;

[0047] A lifting groove 16, which is provided on the inner wall of the first support arm 2, and a pressing plate 17 is slidably installed in the lifting groove 16, and the pressing plate 17 is located directly above the winding roller 4;

[0048] A lifting assembly, which is located on the first support arm 2 and is used to change the height of the pressing plate 17 in the vertical direction;

[0049] The dust removal mechanism includes a dust removal box 23, multiple fans 24 and a filter 25, wherein the dust removal box 23 is fixedly mounted on the side wall of the pressure plate 17, multiple fans 24 are installed in the inner cavity of the dust removal box 23, and the filter 25 is magnetically connected to the bottom opening of the dust removal box 23 through a magnet.

[0050] Among them, when the acrylic protective film is rolled up, first, the operator can adjust the position of the side plate 6 on the winding roller 4 according to the actual width of the acrylic protective film. The operator can move the side plate 6 to the left or right by rotating the rotary rod 15 in the adjustment component. After the adjustment is completed, the motor 21 in the lifting component is started, and the pressure plate 17 is driven to press down through multiple transmission mechanisms until the lower surface of the pressure plate 17 contacts the acrylic protective film. At this time, the motor 15 is started, and the output shaft of the motor 15 rotates to drive the winding roller 4 to rotate and roll up the acrylic protective film. As the acrylic protective film is continuously rolled up, the motor 21 reverses and drives the pressure plate 17 to move upward through the transmission mechanism. In this process, the pressure plate 17 is pressed downward. The arc groove 28 on the plate 17 is always in close contact with the surface of the acrylic protective film to ensure that the wrinkles of the acrylic protective film are smoothed during the rolling process without causing excessive squeezing of the acrylic protective film roll. It is worth adding that in the process of rolling up the acrylic protective film roll, multiple fans 24 are always in the started state, the fans 24 generate suction, and the scraper 27 is against the upper surface of the acrylic protective film roll. The dust on the upper surface of the acrylic protective film roll is adsorbed on the filter screen 25 along the upper surface of the scraper 27. When cleaning the filter screen 25, the operator only needs to pull the filter screen 25 downward to separate the filter screen 25 from the dust removal box 23, and then reset the filter screen 25 after cleaning with clean water.

[0051] By setting an adjustment component, using the motor 15, the driven wheel 9, the moving plate 12, the moving plate 12 and the push rod 14 for transmission, the operator turns the rotary rod 15 to drive the side plate 6 to slide left or right, thereby changing the position of the side plate 6 on the winding roller 4, so that the device can timely adjust the actual utilization width of the winding roller 4 according to the acrylic protective film of different widths, avoiding the situation in the traditional winding device that the winding roller 4 is too long and the coil is prone to deflection and deviation during winding; by setting a lifting component, using the motor 21 for driving, and through the threaded rod 18, the bevel gear 19 and the bevel gear 20, the side plate 6 can be driven to slide left or right, thereby changing the position of the side plate 6 on the winding roller 4. The gear 20 and the like are used for transmission, so that the pressing plate 17 can be freely displaced along the lifting groove 16, ensuring that the pressing plate 17 is always in contact with the surface of the acrylic protective film, so that the acrylic protective film will not be wrinkled during the winding process, which greatly improves the aesthetics of the finished product after the acrylic protective film is rolled up; by setting a dust removal mechanism, the suction force generated by the fan 24 is utilized, and the scraper 27 is used to scrape the dust on the upper surface of the acrylic protective film, so that the dust on the upper surface of the acrylic protective film can be fully cleaned, ensuring the neatness of the acrylic protective film after rolling, and further improving the quality of the acrylic protective film coil.

[0052] Embodiment 2:

[0053] This embodiment provides a winding device for producing acrylic protective film, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the adjustment component includes:

[0054] The housing 7 is fixedly mounted on the inner side wall of the second support arm 3 and close to the winding roller 4.

A limiting block 10 is fixed on the side of the driven wheel 9 away from the side plate 6. An annular groove 11 is provided on the inner side wall of the housing 7 to accommodate the rotation of the plurality of limiting blocks 10. A movable plate 12 is slidably connected to the inner cavity of the housing 7 on the side of the plurality of driven wheels 9 close to the side plate 6. The driven wheels 9 are coaxially connected to the inner cavity of the housing 7. A screw rod 13 is connected, and the other end of the screw rod 13 passes through the movable plate 12 and extends to the inner wall of the other side of the shell 7. The movable plate 12 is threadedly connected to multiple screw rods 13. Push rods 14 are symmetrically fixed to the side wall of the movable plate 12, and one end of the push rod 14 passes through the inner wall of the shell 7 and extends to the outside and is fixed to the side wall of the side plate 6. A rotating rod 15 is provided on the outer wall of the second support arm 3, and one end of the rotating rod 15 passes through the outer wall of the second support arm 3 and extends to the inner cavity of the shell 7 and is coaxially connected to the driving wheel 8.

[0055] Among them, when the adjustment component is working, the operator rotates the rotary rod 15, the rotary rod 15 drives the active wheel 8 to rotate, and the active wheel 8 drives multiple driven wheels 9 on the surrounding side to rotate synchronously, and the screw rod 13 on the driven wheel 9 will also rotate at the same time. Under the action of the thread force, the movable plate 12 can slide to the left or right in the inner cavity of the shell 7. When the movable plate 12 slides, it will drive the side plate 6 to move synchronously through the push rod 14, that is, the side plate 6 can slide left or right along the winding roller 4.

[0056] By arranging the motor 15, the driven wheel 9, the movable plate 12, the movable plate 12 and the push rod 14, the operator can rotate the rotary rod 15 to drive the side plate 6 to slide to the left or right, thereby changing the position of the side plate 6 on the winding roller 4, so that the device can timely adjust the actual utilization width of the winding roller 4 according to the acrylic protective film of different widths, avoiding the situation in the traditional winding device that the winding roller 4 is too long, which makes the coil easily deflect or run crooked when winding.

The top end of the threaded rod 18 is coaxially connected with a bevel gear 19. The circumferential side of the bevel gear 19 is meshed with a bevel gear 20. A motor 21 is installed on the upper surface of the first support arm 2, and the output shaft of the motor 21 is coaxially connected with the bevel gear 20. The threaded rod 18 is threadedly connected to the pressure plate 17.

[0060] Among them, when the lifting assembly is working, the motor 21 is started, the output shaft of the motor 21 rotates, and drives the bevel gear 20 to rotate, the bevel gear 20 drives the bevel gear 19 to rotate, and the bevel gear 19 drives the threaded rod 18 to rotate. Under the action of the thread force, the pressure plate 17 can be freely displaced up and down in the lifting groove 16. The operator can adjust the forward and reverse rotation of the motor 21 according to actual needs to change the upward or downward movement of the pressure plate 17, so that the lower surface of the pressure plate 17 is always in contact with the surface of the acrylic protective film, so as to ensure that the wrinkles of the acrylic protective film are smoothed during the winding process without causing excessive squeezing of the acrylic protective film roll.

[0061] By setting a lifting component, driving it with motor 21, and transmitting it through threaded rod 18, bevel gear 1 19 and bevel gear 2 20, the pressing plate 17 can be freely displaced along the lifting groove 16, ensuring that the pressing plate 17 is always in contact with the surface of the acrylic protective film, so that the acrylic protective film will not be wrinkled during the rolling process, which greatly improves the aesthetics of the finished product of the acrylic protective film after rolling.
