Description

Technical Field

[0001] This application relates to the field of protective film production technology, and more specifically, to a protective film production coating apparatus. Background Technology

[0002] The protective film coating device is a special equipment used to uniformly coat the adhesive layer in the production of protective film. It mainly consists of an unwinding mechanism, a coating mechanism, a winding mechanism, and a control system. Its working principle is that after the protective film is unwound from the unwinding mechanism, it is uniformly coated with adhesive by the coating mechanism and then wound into a finished product by the winding mechanism. During the process, the tension system ensures that the material runs smoothly.

[0003] In related technologies, for example, the prior art patent with publication number CN216500323U provides a coating device for the production of protective film. This device, by setting a movable column, allows one end of the air shaft to slide into or out of the fixed frame in cooperation with the movable column, slide rail, fixed frame and slide groove, so that the protective film can be easily wound up or removed after being wound up.

[0037] The present application will be further described in detail below with reference to the accompanying drawings.

[0038] Reference Figure 1 This application discloses a protective film production coating device, including a base plate 1. An unwinding assembly 2 is provided on the top of the base plate 1 for unwinding uncoated protective film rolls. An coating assembly 3 is provided on one side of the unwinding assembly 2 for coating the protective film with adhesive. A drying chamber 4 is provided on the side of the coating assembly 3 away from the unwinding assembly 2 for air drying the coated protective film. A winding assembly 5 is provided on the side of the drying chamber 4 away from the coating assembly 3 for winding the coated protective film. An opening and closing assembly 6 is provided on the top of the base plate 1 for opening and closing one side of the unwinding assembly 2 and the winding assembly 5.

[0039] After the opening and closing component 6 drives one side of the unwinding component 2 and the winding component 5 to open, the uncoated protective film roll is placed inside the unwinding component 2. Then, the opening and closing component 6 drives one side of the unwinding component 2 and the winding component 5 to close, and the uncoated protective film passes through the coating component 3 and the drying chamber 4, and is fixed to the protective film roll on the winding component 5. Then, the unwinding component 2 unwinds the protective film, and the coating component 3 applies adhesive to the protective film. The drying chamber 4 dries the coated protective film. Finally, the winding component 5 winds the film, completing the coating process for the protective film.

[0040] Reference Figure 1 , Figure 2 and Figure 5The unwinding assembly 2 includes an unwinding shaft 21, which is fixedly mounted on the output end of the drive motor A22. The drive motor A22 is fixedly mounted on the outside of the support base A23. The winding assembly 5 includes a winding roller 51, which is fixedly mounted on the output end of the drive motor B52. The drive motor B52 is fixedly mounted on the outside of the support base B53.

[0041] The unwinding shaft 21 is driven to rotate by the drive motor A22, which in turn unwinds the protective film roll. The take-up roller 51 is driven to rotate by the drive motor B52, which then takes the coated protective film back up.

[0042] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 A swivel shaft A211 is fixedly installed at the end of the unwinding shaft 21 away from the drive motor A22, and a swivel shaft B511 is fixedly installed at the end of the take-up roller 51 away from the drive motor B52. The opening and closing assembly 6 includes a sliding plate 61, which is slidably mounted on the top of the base plate 1 via a slide rail 11. An electric push rod B62 is fixedly installed inside the sliding plate 61 corresponding to the unwinding assembly 2 and the take-up assembly 5. Bearings 63 are fixedly installed at the output ends of both electric push rods B62. A mating block 64 is rotatably mounted on the inner side of the bearing 63, and the outer side of the mating block 64 is aligned with the outer side of the bearing 63. The roller A211 and roller B511 are provided with flower holes 641. The unwinding roller 21 is provided with a sliding groove A212 at the end away from the drive motor A22. The winding roller 51 is provided with a sliding groove B512 at the end away from the drive motor B52. A threaded sleeve 65 is fixedly provided on the outer side of the mating block 64 corresponding to the sliding grooves A212 and B512. A threaded moving ring 651 is provided on the outer side of the threaded sleeve 65. The sliding plate 61 is fixedly provided on the output end of the electric push rod A611. The electric push rod A611 is fixedly provided on the top of the base plate 1.

[0043] When one side of the unwinding assembly 2 and the winding assembly 5 is opened, the bearing 63 is moved by the electric push rod B62, thereby causing the mating block 64 and the threaded sleeve 65 to disengage from the corresponding unwinding shaft 21 and the winding roller 51. Then, the sliding plate 61 is driven to slide on the top of the slide rail 11 by the electric push rod A611, so that one side of the unwinding assembly 2 and the winding assembly 5 is opened. By moving in the opposite direction, one side of the unwinding assembly 2 and the winding assembly 5 can be closed. The mating block 64 rotates inside the bearing 63, and the flower hole 641 cooperates with the corresponding flower shaft A211 and flower shaft B511, so that flower shaft A211 and flower shaft B511 can rotate normally.

[0044] The protective film roll can be limited by the support base A23, support base B53 and the corresponding threaded moving ring 651. By rotating the threaded moving ring 651, the threaded moving ring 651 can move outside the threaded sleeve 65, so that the unwinding assembly 2 and the winding assembly 5 can be adapted to protective film rolls of different lengths.

[0045] Reference Figure 1 and Figure 3 The glue application assembly 3 includes a glue application roller 31, which is rotatably disposed inside the glue tank 32. The glue tank 32 is fixedly disposed on the top of the base plate 1. A pressure roller 33 is rotatably disposed on the top of the glue application roller 31. The pressure roller 33 is rotatably disposed inside two support plates 34. The two support plates 34 are fixedly disposed on both sides of the glue tank 32. A glue inlet pipe 35 is disposed on the outside of the glue tank 32. A groove 341 is opened inside the support plate 34. The two sides of the pressure roller 33 are rotatably disposed outside the corresponding slider 331. The slider 331 is slidably disposed inside the corresponding groove 341. A spring 332 is fixedly disposed between the top of the slider 331 and the inside of the corresponding groove 341.

[0046] The slider 331 is slidably set inside the groove 341, so that the protective film can pass between the pressure roller 33 and the glue coating roller 31. Through the elastic action of the spring 332, the pressure roller 33 can press down on the protective film, so that the protective film is in close contact with the glue coating roller 31 and the pressure roller 33. The glue can be added to the glue box 32 through the glue inlet pipe 35.

[0047] Reference Figure 1 and Figure 4 The drying box 4 is fixedly installed on the top of the base plate 1. A set of conveyor rollers 41 are provided on both sides of the drying box 4, and a fan 42 is provided on the outside of the drying box 4.

[0048] The drying chamber 4 can be opened by the fan 42, which makes it easy to pass the protective film through the two sets of conveyor rollers 41. The fan 42 blows air into the inside of the drying chamber 4 to accelerate the drying of the colloid on the outside of the protective film.

[0049] In summary, when the protective film production coating device disclosed in this application is in use, the bearing 63 is moved by the electric push rod B62, thereby causing the mating block 64 and the threaded sleeve 65 to disengage from the corresponding unwinding shaft 21 and take-up roller 51. Then, the sliding plate 61 is driven to slide on the top of the slide rail 11 by the electric push rod A611, so that one side of the unwinding assembly 2 and the take-up assembly 5 is opened, and the uncoated protective film roll is placed inside the unwinding assembly 2. Then, the unwinding assembly 2 and the take-up assembly 5 are closed by the opening and closing assembly 6. The mating block 64 rotates inside the bearing 63, and the flower hole 641 cooperates with the corresponding flower shaft A211 and flower shaft B511, so that the flower shaft A211 and flower shaft B511 can rotate normally.

[0050] The uncoated protective film is passed through the coating assembly 3 and slidably positioned inside the chute 341 by the slider 331, so that the protective film can pass between the pressure roller 33 and the coating roller 31. The drying box 4 can be opened by the fan 42, so that the protective film can pass through the two sets of conveying rollers 41. Finally, the uncoated protective film is fixed to the take-up roller 51.

[0051] Subsequently, the unwinding shaft 21 is driven to rotate by the drive motor A22, which drives the protective film roll to unwind. The protective film passes through the coating assembly 3, and the coating roller 31 coats the protective film with adhesive. The fan 42 blows air into the inside of the drying chamber 4 to accelerate the drying of the adhesive on the outside of the protective film. The take-up roller 51 is driven to rotate by the drive motor B52 to take up the coated protective film, thus completing the coating process of the protective film.
