[0019] Example 1

[0020] As shown in Figures 1 to 5, the composite nonwoven fabric thermal rolling coating device proposed in this utility model includes a processing box 1, a first guide roller 3, a second guide roller 301, and a cleaning mechanism. Two sets of feeding rollers 2 are symmetrically and detachably installed at one end of the processing box 1. The feeding rollers 2 are driven to rotate by a motor mounted on the processing box 1. Composite nonwoven fabric and a protective film are respectively wound on the two sets of feeding rollers 2. A thermal rolling coating mechanism 4 is provided at the other end of the processing box 1. The thermal rolling coating mechanism 4 is existing technology and can perform thermal rolling coating on composite nonwoven fabric and a protective film. The specific structure and principle are detailed in the patent with authorization announcement number CN222246187U, and will not be repeated here. Two sets of first guide rollers 3 are provided, and the two sets of first guide rollers 3 are driven to rotate by a motor mounted on the processing box 1. The two sets of first guide rollers 3 are symmetrically installed... On the processing box 1, there are two sets of second guide rollers 301. The two sets of second guide rollers 301 are driven to rotate by motors installed on the processing box 1. The two sets of second guide rollers 301 are symmetrically installed on the processing box 1. There are two sets of cleaning mechanisms. The two sets of cleaning mechanisms are installed on the processing box 1 and are located between the corresponding first guide rollers 3 and second guide rollers 301. The cleaning mechanism consists of multiple sets of cleaning seats 5 connected in sequence, an absorption pipe 503 connected to the output end of the cleaning seat 5, and a filter screen 504 installed inside the cleaning seat 5. The cleaning seat 5 is provided with a clearance groove 501. Multiple sets of absorption ports 502 are evenly opened at the top and bottom of the clearance groove 501 and on the cleaning seat 5. The filter screen 504 corresponds to the absorption pipe 503. The output end of the absorption pipe 503 extends to the outside of the processing box 1 and is connected to the external suction mechanism.

[0021] Furthermore, the bottom or top end of the outer peripheral surface of the first guide roller 3 is located on the same horizontal plane as the top or bottom end of the outer peripheral surface of the second guide roller 301, which facilitates the flattening of the passing composite nonwoven fabric or protective film and makes it easier for the cleaning mechanism to clean impurities such as fibers.

[0022] Furthermore, the cleaning seat 5 is U-shaped, and two adjacent sets of cleaning seats 5 are connected by a connecting rod. The cleaning seat 5 is equipped with a mounting bracket, which is connected to the rear side wall of the processing box 1 by bolts. The setting of multiple sets of cleaning seats 5 improves the cleaning efficiency of composite non-woven fabric and protective film surface.

[0023] Furthermore, a connecting seat 505 is installed at the bottom of the filter screen 504, and a receiving box 506 is installed at the bottom of the connecting seat 505. The connecting seat 505 is connected to the bottom of the cleaning seat 5 by bolts. The filter screen 504 is slidably connected to the cleaning seat 5, and the bottom of the cleaning seat 5 has a discharge port corresponding to the receiving box 506.

[0024] In this embodiment, the feeding roller 2, which is wound with composite nonwoven fabric or protective film, is installed on the corresponding motor output end on the processing box 1. Then, the end of the composite nonwoven fabric or protective film passes through the first guide roller 3, then through the relief groove 501 on multiple sets of cleaning seats 5, then through the second guide roller 301, and finally through the hot rolling coating mechanism 4. Then, the door on the processing box 1 is closed, and the external suction mechanism is started. When the composite nonwoven fabric or protective film is moved on the working line, the fibers and other impurities on its surface are sucked into the inner cavity of the cleaning seat 5 through multiple sets of absorption ports 502. After the impurities enter the interior of the cleaning seat 5, they are filtered and intercepted by the filter screen 504. Excess gas enters the external suction mechanism through the absorption pipe 503 and is discharged from the output end of the external suction mechanism. After a period of use, the bolts between the connecting seat 505 and the cleaning seat 5 are removed, the receiving box 506 is separated from the cleaning seat 5, and then the filter screen 504 is slid outward along the cleaning seat 5 to remove the intercepted impurities.

[0025] Example 2

[0026] As shown in Figures 2 to 4, the composite nonwoven fabric thermal rolling coating device proposed in this utility model, compared with Embodiment 1, has an anti-clogging mechanism on the cleaning mechanism. The anti-clogging mechanism includes a drive assembly, a slide rod 604, and a cleaning brush 605. The drive assembly is disposed on one of the cleaning seats 5. The slide rod 604 is driven by the drive assembly to slide back and forth along the horizontal direction of multiple sets of cleaning seats 5. Multiple sets of cleaning brushes 605 are provided. The cleaning brushes 605 are mounted on the slide rod 604, and the bristles on the cleaning brushes 605 are in contact with the corresponding filter screens 504.

[0027] Furthermore, the drive assembly includes a support frame 6, a toothed plate 601, and an incomplete gear 603; the support frame 6 is mounted on the cleaning seat 5; the toothed plate 601 is slidably connected to the support frame 6, and an elastic element 602 is sleeved on one end of the toothed plate 601. The elastic element 602 is a spring, and one end of the elastic element 602 is connected to the support frame 6, and the other end of the elastic element 602 is connected to the support frame 6; the incomplete gear 603 is driven to rotate by a motor mounted on the cleaning seat 5, and the incomplete gear 603 is intermittently meshed with the toothed plate 601.

[0028] In this embodiment, when cleaning the surface of the non-woven fabric and protective film, the controller starts the motor to drive the incomplete gear 603 to rotate. The incomplete gear 603 intermittently meshes with the toothed plate 601, causing the toothed plate 601 to slide horizontally away from the elastic member 602 along the support frame 6, thereby squeezing the elastic member 602. When the incomplete gear 603 no longer meshes with the toothed plate 601, the elastic member 602 recovers its elasticity and drives the toothed plate 601 to slide along the support frame 6 towards the elastic member 602. This process repeats, thereby driving the slide rod 604 to slide horizontally along the cleaning seat 5, and driving the cleaning brush 605 to slide left and right along the filter screen 504, pushing the impurities attached to the filter screen 504 to both sides. Under the action of gravity, the impurities fall into the receiving box 506 for collection, preventing the filter screen 504 from being blocked by impurities and interfering with the absorption of impurities, reducing the cleaning frequency of the filter screen 504, and improving the cleaning efficiency.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
