[0018] An automatic tearing roll assembly structure, such as Figure 1-3 As shown, the automatic paper tearing roll assembly structure includes a cleaning roller 1, a sticky roller 2 arranged above or below the cleaning roller 1, a bottom plate 3, a transverse movement mechanism 4, two sets of rotating mechanisms 5 arranged at the same height, and two sets of film tearing mechanisms 6. A sticky paper roll 21 is wound on the surface of the sticky roller 2. When the cleaning roller 1 cleans the surface of the object to be cleaned, the sticky roller 2 drives the sticky paper roll 21 to press the cleaning roller 1 under external drive. The bottom plate 3 is used to be fixed to the outside, and the transverse movement mechanism 4 is a rodless cylinder, which is horizontally fixed on the front of the bottom plate 3. The rotating mechanism 5 is provided with a rotary cylinder 51 and a cylinder mounting plate 52. One rotary cylinder 51 is installed on the driving end of the rodless cylinder through its cylinder mounting plate 52, and the other rotary cylinder 51 is directly fixedly connected to the bottom plate 3 on the outside of the rodless cylinder through its cylinder mounting plate 52 and the support plate. The two sets of film-tearing mechanisms 6 are correspondingly mounted on the two sets of rotating mechanisms 5 of equal height, and are arranged at the two ends directly above or below the sticky roller 2, and are both located on the side of the sticky roller 2 away from the cleaning roller 1. The film-tearing mechanism 6 is provided with a first mounting plate 61, a first cylinder 62, a film-tearing assembly 63, a film-clamping assembly 64, a second cylinder 65 and a second mounting plate 66. The second cylinder 65 is a slide cylinder, and the second cylinder 65 is vertically fixed to the driving end of the rotary cylinder 51 through the second mounting plate 66. The first cylinder 62 adopts an ACQ thin cylinder, which is vertically mounted downward on the front of the first mounting plate 61, and the first cylinder 62 is fixed to the driving end of the second cylinder 65 through the first mounting plate 61. The film-tearing assembly 63 is provided with a fixed seat 631 and a film-tearing wheel 632 mounted at the lower end of the fixed seat 631 and capable of rotating, and the fixed seat 631 is mounted at the driving end of the first cylinder 62. The film clamping assembly 64 is installed on the side of the first mounting plate 61. The film clamping assembly 64 is provided with a clamping claw 642 and a film clamping cylinder 641 for driving the clamping claw 642 to clamp the film head (the film head here is understood as the head of the paper roll, and the paper roll can be regarded as the film), and the two film clamping assemblies 64 are located on the inner sides of the two film assemblies 63.

[0019] The present invention arranges a film tearing mechanism above or below both ends of the sticky paper roll. When the sticky paper roll wound on the surface of the sticky roller needs to be torn off, the film peeling wheel and the sticky paper roll are in a crimping state, the film clamping cylinder drives the clamping claw to open, and the sticky roller rotates around its center in the direction of the sticky paper roll winding under external drive, so that the film peeling wheel contacts and adheres to the outer end head of the sticky paper roll, and the outer end head of the sticky paper roll is driven to move upward by the rotation of the film peeling wheel. After the detection component (not shown in the figure) detects that the outer end head of the sticky paper roll enters the clamping position of the clamping claw, the film clamping cylinder drives the clamping claw to shrink and clamp the outer end head of the sticky paper roll, so that the present application can automatically tear off the sticky paper roll on the sticky roller, improve work efficiency and reduce product cleaning costs, and also improve the degree of automation of the cleaning equipment. The first cylinder is used to drive the lifting and lowering of the film peeling wheel, crimp the sticky paper roll, and raise the height of the adhesive sticky paper roll head and make the film peeling wheel separate from the bonding state with the sticky paper roll head. The transverse movement mechanism is used to drive the two sets of film tearing mechanisms to adjust the distance to adapt to the sticky paper rolls of different lengths, so that the two film tearing wheels are located at the edge of both sides of the sticky paper roll, thereby improving the film tearing efficiency.

[0020] As a preference, Figure 3 As shown, a slide plate 67 is fixedly installed on the driving end of the second cylinder 65, a connecting block 671 is fixed on the upper front end of the slide plate 67, a through groove is opened on the upper end of the first mounting plate 61, the slide plate 67 is fixedly connected to the first mounting plate 61 in the through groove through the connecting block, and the slide plate 67 is also connected to the first mounting plate 61 through a slider of the vertical slide rail assembly 672 below the connecting block 671.

[0021] Through this arrangement, when the rotary cylinder drives the film tearing mechanism to rotate, the first mounting plate is connected through the connecting block at the upper end and the slide block of the slide rail assembly at the middle and lower ends, so that the whole formed by the first mounting plate and the parts connected in front of it has good safety and stability during the rotation process.

[0022] As a preference, Figure 4 , 5As shown, the fixed seat 631 is provided with a seat body 6311, a movable block 6312 and a spring 6313; the seat body 6311 is installed at the driving end of the first cylinder 62, and is slidably connected to the first mounting plate 61 through a slide rail assembly. The seat body 6311 is provided with two parallel clamping plates 6311a and a connecting plate 6311b connecting the tops of the two clamping plates 6311a. A vertical waist-shaped hole is provided in the middle of the two clamping plates 6311a, an outer opening groove is provided below the waist-shaped hole, and an upper limit hole is provided at the center of the lower end of the connecting plate 6311b. The movable block 6312 is a U-shaped structure, and the U-shaped opening is downward. The lower ends of the left and right side plates of the movable block 6312 are both provided with lower opening grooves, and the outer walls of the left and right side plates are provided with protruding limit columns. The top of the movable block 6312 is provided with a lower limit hole corresponding to the upper limit hole. The movable block 6312 is slidably clamped between the two clamping plates 6311a, the limiting columns on both sides are correspondingly located in the waist-shaped holes of the two clamping plates, the two ends of the spring 6313 are correspondingly located in the upper limit hole and the lower limit hole, and the shaft heads at both ends of the film lifting wheel 632 are inserted into the lower opening groove and the outer opening groove on the corresponding side.

[0023] The present invention arranges the movable block between the two clamping plates of the seat body by sliding, and uses a spring to make the limiting column always at the bottom of the waist-shaped hole, and positions the film-lifting roller by the vertically arranged outer opening groove and lower opening groove. Therefore, the film-lifting roller is firmly fixed during operation, and when the film-lifting roller needs to be replaced, it only needs to push the movable block to make the shaft head of the film-lifting wheel disengage from the lower opening groove and then take out the film-lifting wheel. The replacement is convenient, and it saves time and effort.

[0024] As a preference, Figure 6 As shown, the clamping claw 642 is composed of a film clamping fixed block 6421 and a film clamping movable claw 6422. The film clamping fixed block 6421 is fixedly mounted on the side of the first mounting plate 61. The film clamping cylinder 641 is horizontally fixed on the film clamping fixed block 6421. The left and right surfaces of the film clamping fixed block 6421 protrude to the left and right sides at the front lower end of the cylinder body of the film clamping cylinder 641, and one of the protruding sides is as close to the side of the film lifting wheel 632 as possible, so that the front surface of the protruding part is an outward convex arc surface. In the initial state, the arc surface is colinear with the axis of the film lifting wheel 632, and the arc radius of the arc surface is slightly smaller than the radius of the film lifting wheel 632. The film clamping movable claw 6422 is fixed on the driving end of the film clamping cylinder 641, and the film clamping movable claw 6422 is provided with an inner concave arc surface matching the arc surface.

[0025] The present invention sets the clamping part of the lower end of the clamping jaw as an arc surface, and designs it to be concentric with the outer circle of the film-lifting wheel in the initial state, and one side of the protruding part is close to the side of the film-lifting wheel, so that after the film-lifting wheel lifts the film on the outer end of the sticky paper roll, it can quickly enter the clamping range of the clamping jaw, thereby improving the film lifting and clamping efficiency. Example

[0026] A cleaning device having the automatic tearing roll assembly structure of embodiment 1, such as Figure 6 ,7 As shown, the cleaning device 100 is also provided with a box 7, a waste transfer mechanism 8 and a drawer box 9. The cleaning roller 1, the dust sticking roller 2, the bottom plate 3, the film tearing mechanism 6 and the waste transfer mechanism 8 are all located in the box 7, and the film tearing mechanism 6 is fixed to an inner wall of the box 7 through the bottom plate 3. The waste transfer mechanism 8 is arranged in front of the dust sticking roller 2 and the film tearing mechanism 6. The waste transfer mechanism 8 is provided with a slide module 81, a linear rail assembly 82, a movable plate 83 and a waste clamping assembly 84. The slide module 81 adopts the TOYO-GTH8-L5 slide module, which is horizontally fixedly installed on one side wall of the box body 7 perpendicular to the bottom plate 3, and the linear rail assembly 82 is horizontally installed on the other side wall of the box body 7 perpendicular to the bottom plate 3 through a fixed plate. One end of the movable plate 83 is fixed to the driving end of the slide module 81, and the other end is fixed to the slider of the linear rail assembly 82. The waste clamping assembly 84 adopts the structure of the cylinder clamp 642, which is installed on the lower surface of the movable plate 83. The waste clamping component 84 is used to dock with the film clamping component 64. After the film clamping component 64 clamps the outer end of the sticky paper roll 21, the waste clamping component 84 moves between the two film clamping components 64 through the slide module 81 and also clamps the outer end of the sticky paper roll 21. Then the clamping claws 642 of the film clamping component 64 are released, and the waste clamping component 84 clamps the paper roll head and moves, driving the sticky paper roll 21 to gradually release the sticky paper to a certain length. The external cutting mechanism cuts off the front end paper roll or the front end paper roll breaks at the cutting line under the action of the tensile tension, and the waste clamping component 84 continues to drive the cut paper roll waste 200 to enter the next workstation. Preferably, the waste clamping assembly 84 is configured to be compatible with the film tearing mechanism 6, and two groups of cylinder clamps 642 are installed on the lower surface of the movable plate 83, one group is fixed on the movable plate 83, and the other group is slidably arranged along the length direction of the movable plate 83, so as to match with the film tearing mechanism 6 connected to the driving end of the rodless cylinder, and is used for adjusting the distance between the two waste clamping assemblies 84 to adapt to sticky paper rolls 21 of different lengths.

[0027] The pull-out box 9 is composed of a material box pull plate 91 and a waste material bottom plate 923 connected in a T shape, and a handle 93 is provided on the outer wall of the material box pull plate 91; the cleaning equipment 100 is provided with a waste material 200 outlet 71 on the side wall of the box body 7 and below the slide module 81 or the linear rail assembly 82, and the box body 7 is fixed with a pull-out rail assembly 94 on the inner wall along the lower edge of the waste material outlet 200 71. The material pull box is slidably connected to the box body 7 at the waste material outlet 200 71 through the waste material bottom plate 923 and the pull-out rail assembly 94 to form a drawer-type entry and exit structure.

[0028] The cleaning equipment of the present invention can be arranged on one side or two sides according to the single-sided or double-sided cleaning requirements of the object. When arranged on both sides, two layers of cleaning rollers are used to clean the upper and lower surfaces of the object to be cleaned at the same time, and the automatic tearing paper roll assembly structure is arranged symmetrically up and down. Other mechanisms can refer to the above features. In the case where the outer end of the sticky paper roll needs to be torn off, the film lifting wheel presses the sticky paper roll to lift the film head, and the clamping claws of the film clamping assembly clamp the film head (the second cylinder can choose to drive or not drive the tearing film mechanism to lift as a whole through program settings), the slide module drives the moving plate and the waste clamping assembly to move to the appropriate position, the waste clamping mechanism docks with the film clamping assembly, the clamping claws of the waste clamping mechanism clamp the film head, the clamping claws of the film clamping assembly release the film head, and the waste clamping mechanism drives the waste to move and release it on the waste bottom plate of the pull-out box. After the waste on the waste bottom plate accumulates to a certain extent, the waste bottom plate can be pulled out by the handle, and then the waste on it can be removed. The present invention is easy to use and can automatically tear off the film, thereby improving the automation level of the cleaning equipment. Since all the moving mechanisms are arranged in the box body and are arranged through the rotating mechanism in the automatic paper tearing roll assembly structure, when the film tearing wheel needs to be replaced, the rotating mechanism can be used to drive the film tearing mechanism to rotate 180°, so that the film tearing wheel above the cleaning roller is at the uppermost end, and the film tearing wheel below the cleaning roller is at the bottom, and then the film tearing wheel can be disassembled and replaced through the inspection port at the corresponding position of the box body, thereby ensuring the safety of the staff.

[0029] The present invention is not limited to the above-mentioned specific implementation modes. For ordinary technicians in this field, various changes made based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
