[0045] Example 1

[0046] See also Figure 1-7 As shown, a PVC film surface cleaning device comprises a cleaning box 1 and a cleaning box 2, wherein the cleaning box 1 is horizontally arranged and the cleaning box 2 is inclined;

[0047] The cleaning box 1 is connected to the cleaning box 2 via a connecting box 3, and the connecting box 3 is used to form a bending area at the connection part of the cleaning box 1 and the cleaning box 2 to prevent the liquid used for cleaning the PVC film from flowing back;

[0048] A plurality of conveying components 6 are installed on the upper side of the cleaning box 1, and a plurality of cleaning units 4 are arranged inside the cleaning box 1. A first positioning roller group 5 is installed inside and at both ends of the cleaning unit 4, and a spraying rack 7 is installed inside the cleaning unit 4. The spraying rack 7 is connected to the corresponding conveying component 6, and the spraying rack 7 is located outside the moving path of the PVC film. When the PVC film passes through, the first positioning roller group 5 limits its moving path, thereby facilitating the immersion of the PVC film in the cleaning unit 4;

[0049] In this embodiment, the spray rack 7 is arranged on both sides of the interior of the cleaning unit 4, and is used to transport the cleaning liquid into the interior of the cleaning unit 4, and form a certain depth of immersion liquid in the cleaning unit 4;

[0050] A contact platform 10 is installed inside the cleaning box 2, and a first connection box 8 and a second connection box 9 are installed on the upper side of the cleaning box 2 along the moving direction of the PVC film. Cleaning components 14 are installed inside the first connection box 8 and the second connection box 9. When the PVC film passes by, the two groups of cleaning components 14 contact the PVC film to clean it.

[0051] And two groups of cleaning components 14 are respectively arranged on both sides of the cleaning box 2, and the two groups of cleaning components 14 rotate relatively.

[0052] See also Figure 3 As shown, the connecting box 3 is an inverted V-shape, and a second positioning roller group 13 is installed inside the connecting box 3. The second positioning roller group 13 is used to constrain the moving path of the PVC film inside the connecting box 3 to prevent the PVC film from contacting the inner wall of the connecting box 3 when moving, thereby causing damage to the PVC film;

[0053] A water outlet is provided on the lower side of one end where the connecting box 3 is connected to the cleaning box 2. When the PVC film moves upward along the cleaning box 2, the liquid on the surface of the PVC film slides downward and is discharged along the water outlet at the connection portion between the cleaning box 2 and the connecting box 3.

[0054] See also Figure 4-6As shown, the cleaning assembly 14 includes a rotating mechanism 141 and a rotating frame 144, and the rotating frame 144 is arranged outside the rotating mechanism 141;

[0060] The cleaning member 145 is rolled up on the outer side of a group of driving roller bodies. After the cleaning member 145 is moved out of the group of driving roller bodies, it goes around the lower side of the corresponding contact roller 142 and is rolled up to the outer side of another group of driving roller bodies.

[0061] After the two sets of driving roller bodies are started simultaneously, the position of the cleaning member 145 at the lower side of the contact roller 142 is changed.

[0062] See also Figure 7 As shown, the contact roller 142 includes a central shaft 1421, and a rotating sleeve 1422 is rotatably connected to the outer side of the central shaft 1421;

[0063] In this embodiment, a driving mechanism is installed at one end of the central shaft 1421, and the output end of the driving mechanism is connected to the rotating sleeve 1422. After the driving mechanism is started, the rotating sleeve 1422 is driven to rotate outside the central shaft 1421;

[0064] The rotating sleeve 1422 is provided with a plurality of working units, each of which corresponds to a contact position between a group of cleaning members 145 and the PVC film.

[0065] A stroke assembly 1423 is installed inside the central shaft 1421. The output end of the stroke assembly 1423 is perpendicular to the contact platform 10 and is installed with a contact member 1424. When the PVC film moves along the contact platform 10, pressure can be applied vertically to the PVC film.

[0066] Each staff member in the rotating sleeve 1422 is provided with a receiving groove 1425, and each receiving groove 1425 is provided with an elastic member 1426 and a pressurizing member 1427;

[0067] An inclined surface block 1428 is installed at one end of each pressure member 1427 facing the central axis 1421 , and an inclined surface is provided on the top of the inclined surface block 1428 facing the direction of rotation of the rotating sleeve 1422 .

[0068] The bottom of the pressure member 1427 is provided with an arc-shaped contact portion to avoid damage to the PVC film when the cleaning member 145 is pressed to contact the PVC film.

[0069] When the present invention is used:

[0070] The PVC film to be cleaned moves along the cleaning box 1, the connecting box 3 and the cleaning box 2. When moving inside the cleaning box 1, based on the first positioning roller group 5, the moving path is covered to the corresponding cleaning unit 4, and at the same time, the conveying component 6 conveys the corresponding cleaning liquid to the corresponding cleaning unit 4, and sprays it out from the spraying frame 7, and cleans the PVC film when it passes by;

[0071] After the PVC film is cleaned along the cleaning box 1, it enters the cleaning box 2 after being bent by the second positioning roller group 13 in the connecting box 3, and slides along the contact platform 10 of the cleaning box 2;

[0072] When the PVC film moves along the contact platform 10, the cleaning liquid on its surface slides down along the inclination direction of the contact platform 10 and is discharged from the water outlet connecting the cleaning box 2 and the connecting box 3;

[0073] When the PVC film moves along the contact platform 10, it passes under the two cleaning components 14, and the rotating mechanism 141 and the rotating frame 144 in the cleaning components 14 are started, driving the two contact rollers 142 and the winding roller group 143 to rotate, and during the rotation, the PVC film is cleaned by the cleaning member 145;

[0074] During cleaning, the stroke assembly 1423 in each contact roller 142 is started, and contacts the inclined surface block 1428 in the corresponding working unit through the contact member 1424, and presses the pressure member 1427 downward by stretching the elastic member 1426. After the pressure member 1427 contacts the cleaning member 145, the cleaning member 145 is pressurized to improve the quality of its contact with the PVC film.

[0075] After the preset cleaning time, the rotating sleeve 1422 rotates a working unit around the central axis 1421. When the inclined block 1428 in the new working unit rotates, the two groups of driving rollers in the winding roller group 143 rotate synchronously, transferring the new part of the cleaning member 145 to the lower side of the contact roller 142 and contacting with the pressure member 1427 in the new group of working units.
