[0001] The invention relates to the technical field of roller coating machines, in particular to a roller coating machine capable of adjusting the thickness of the roller coating. Background Art

[0002] Roller coating machine is a kind of coating equipment, which is mainly used to evenly coat paint on the surface of various materials. Roller coating machine adheres liquid paint to the plate through the rotation and extrusion of the roller, so as to achieve the coating effect.

[0003] In the process of roller coating on the surface of the plate by the roller coating machine in the prior art, due to the different production and processing requirements of different plates, the thickness of the coating to be rolled is also different. However, when the roller coating thickness needs to be adjusted, the staff of the roller coating machine in the prior art needs to adjust the distance between the two rollers based on experience, and then control the thickness of the glue coating by the spacing between the rollers. However, due to errors in manual adjustment and poor uniformity, the thickness of the coating rolled on the surface of the same batch of plates will be different, resulting in a low yield rate of the plates, making the roller coating machine unable to meet people's usage needs.

[0015] The beneficial effects of the present invention are embodied in:

[0016] 1. In the present invention, if it is necessary to roll-coat coatings of different thicknesses on the surface of the plate, the distance between the rubber roller and the steel roller can be adjusted by the driving mechanism inside the two shells. The larger the distance between the rubber roller and the steel roller, the thinner the thickness of the coating on the surface of the plate by the rubber roller; the smaller the distance between the rubber roller and the steel roller, the thicker the thickness of the coating on the surface of the plate by the rubber roller. Thus, the coating thickness of the equipment can be freely adjusted to avoid errors caused by manual adjustment, indirectly improve the yield rate of plate processing, and enable the coating machine to meet people's usage needs.

[0017] 2. In the present invention, if it is necessary to roll-coat the surface of plates of different thicknesses, the telescopic ends of the four electric telescopic rods at the bottom of the two shells can be controlled to adjust the distance between the two shells and the conveyor belt, so that the two rubber rollers can roll-coat the surface of plates of different thicknesses.

[0018] 3. In the present invention, when the plate is placed on the top of the conveyor belt for conveying and coating, since there are limit rods on both sides of the plate, the position of the plate is not easily shifted during the movement, thereby ensuring that the two rubber rollers can accurately coat the top of the plate.

[0019] 4. In the present invention, if a large number of plates need to be roller coated, it is inefficient to manually place the plates on the top of the conveyor belt one by one. At this time, with the help of multiple parts of the feeding mechanism cooperating with each other, the effect of automatic feeding of multiple plates can be achieved, which is convenient for improving the efficiency of the device for roller coating of large quantities of plates and can also reduce the labor intensity of manual workers.

[0043] As a technical optimization scheme of the present invention, a limit block 29 is installed on the top of the outer wall of the two movable plates 7 away from the body 1, a rotating rod 19 is rotatably installed on the outer wall of the two limit blocks 29 away from the movable plates 7, a fixed rod 30 is installed on the outer wall on the side away from the two rotating rods 19, a third sliding groove 31 is opened on the outer wall on the side close to the two fixed rods 30, a third sliding block 32 is installed inside the two third sliding grooves 31, an electric push rod 33 is rotatably installed on the end of the two third sliding blocks 32 away from the third sliding groove 31, and a clamping plate 34 is installed on the telescopic end of the two electric push rods 33. A third driving device is preset on the outer wall of one side of the two limit blocks 29, and the output ends of the two third driving devices are respectively connected to the rotating parts of the two rotating rods 19, so as to drive the two rotating rods 19 to rotate and adjust; a third linear motor is preset inside the two third slide grooves 31, and the two third linear motors can drive the two third sliders 32 to move and adjust inside the corresponding third slide grooves 31, and drive the two electric push rods 33 and the splint 34 to move and adjust synchronously; and a fourth driving device is preset inside the two third sliders 32, and the output ends of the two fourth driving devices are respectively connected to the rotating parts of the two electric push rods 33, so as to drive the two electric push rods 33 and the splint 34 to rotate and adjust.

[0044] In this embodiment, the length of the plate to be roller-coated must be compatible with the spacing between the two limit rods 6 and cannot be less than the length of the sleeve rod 18. The thickness of the plate must be greater than the height of the two limit rods 6 to ensure that the multiple related components in the device can operate normally during use.

[0045] In the present invention, when the user uses the device, Figure 1 As shown, the plate to be rolled and coated is placed on the top of the conveyor belt 2 at the left end. The conveyor belt 2 rotates clockwise to drive the plate to move and transport on the top of the conveyor belt 2. When the plate passes under the two shells 3, the paint can be automatically rolled on the top of the plate with the help of two rubber rollers 11, thereby achieving the effect of automatic rolling coating on the surface of the plate.

[0046] If it is necessary to roll coatings of different thicknesses on the surface of the plate, the four first double-headed screws 15 inside the two shells 3 can be controlled to rotate together, driving the first moving blocks 16 at both ends of the rubber roller 11 and the steel roller 10 to move and adjust inside the corresponding rectangular grooves 14, so that the distance between the rubber roller 11 and the steel roller 10 can be adjusted. The larger the distance between the rubber roller 11 and the steel roller 10, the thinner the thickness of the coating on the plate surface by the rubber roller 11, and the smaller the distance between the rubber roller 11 and the steel roller 10, the thicker the coating on the plate surface by the rubber roller 11, thereby enabling the coating thickness of the equipment to be freely adjusted.

[0047] If it is necessary to roll-coat the surfaces of plates of different thicknesses, the telescopic ends of the four electric telescopic rods 12 at the bottom of the two shells 3 can be controlled to adjust the distance between the two shells 3 and the conveyor belt 2, so that the two rubber rollers 11 can roll-coat the surfaces of plates of different thicknesses.

[0048] After placing the plate on the top of the conveyor belt 2 as mentioned above, if the length of the plate is compatible with the spacing between the two limit rods 6, there is no need to adjust the spacing between the two limit rods 6. If the length of the plate is less than the spacing between the two limit rods 6 and greater than the length of the sleeve rod 18, it is necessary to control the two limit rods 6 to move in a direction close to each other, driving the outer walls of the two limit rods 6 on the side close to each other to abut against the outer walls of the two sides of the plate, but not in close contact. At this time, the plate is located at the top of the conveyor belt 2 for transportation. Since there are limit rods 6 on both sides, the position of the plate is not easy to shift during the movement, thereby ensuring that the two rubber rollers 11 can accurately roll on the top of the plate.

[0049] If a large number of plates need to be roll-coated, it is inefficient to manually place the plates on the top of the conveyor belt 2 in sequence. At this time, the two second double-headed screws 27 can be controlled to drive the two movable plates 7 to move and adjust according to the length of the plates, ensuring that the spacing between the two movable plates 7 is adapted to the length of the plates, and the two limit rods 6 are synchronously controlled to move and adjust so that the spacing between the two limit rods 6 can also be adapted to the length of the plates, and then multiple plates are stacked and placed on the top of the two placement plates 8 until the top plate is lower than the top of the movable plate 7, and then the two first sliders 23 can be controlled to move to the leftmost end inside the corresponding first slide groove 22, driving The two slide bars 24 and the sleeve bar 18 move together to the leftmost end of the two limit bars 6, controlling the two placement plates 8 to move upward together, driving the topmost plate to move upward to a position flush with the top of the sleeve bar 18. At this time, when the two first sliders 23 move toward the right end inside the first slide groove 22 to reset, they can drive the two slide bars 24 and the sleeve bar 18 to push the topmost plate. After pushing it to the top of the conveyor belt 2, the plate can be driven for roller coating with the help of the rotation of the conveyor belt 2. The subsequent plates can repeat the above steps to achieve the effect of automatic loading of multiple plates, which is convenient for improving the efficiency of the device for roller coating of large quantities of plates, and can also reduce the labor intensity of manual labor.

[0050] At the same time, in the process of automatically loading the plate by moving back and forth between the two limit rods 6 with the help of the sleeve rod 18 and the two slide rods 24, since the sleeve rod 18 and the two slide rods 24 are provided with soft pads at the bottom ends, the two placement plates 8 can be moved upward, driving the plate to move upward together, while controlling the top plate to move to a position flush with the bottom of the sleeve rod 18 and the two slide rods 24, so that the two first sliders 23 drive the two slide rods 24 and the sleeve rod 18 to move toward the left end. With the help of the soft pads provided at the bottom of the two slide rods 24 and the sleeve rod 18, impurities attached to the surface of the top plate can be automatically cleaned to prevent the impurities from affecting the subsequent two rubber rollers 11 from rolling the plate surface;

[0051] Furthermore, since the outer walls of the two movable plates 7 on one side away from the machine body 1 are both provided with limit blocks 29, when the top plate moves to a position flush with the two limit blocks 29, the two slide bars 24 and the sleeve bar 18 moving toward the left end cannot drive the top plate to move toward the left end synchronously during the process of cleaning impurities on the plate surface, thereby avoiding the problem of the plate being offset along with the sleeve bar 18 and the two slide bars 24 during the process of cleaning impurities on the plate surface.

[0052] After the two rubber rollers 11 have finished coating the surface of the sheet, as the conveyor belt 2 continues to rotate, the coated sheet is moved to the top of the unloading plate 38 for placement, and the two fourth sliders 37 are controlled to move downward together inside the corresponding fourth slide groove 36, driving the unloading plate 38 and the sheet placed on the top of it to move downward together, thereby achieving the effect of assisting the unloading of the sheet after coating, without the need for manual labor to pick up the coated sheet.

[0053] If the conveyor belt 2 fails during use and the plate cannot be automatically conveyed, after the plate falls on the top of the conveyor belt 2, the two first sliders 23 can be controlled to move toward the right end inside the corresponding first slide groove 22, thereby driving the two slide bars 24 and the sleeve bar 18 to move inside the two limit bars 6 toward the right end, thereby pushing the plate to move on the top of the conveyor belt 2 so that the plate can still be rolled and coated. After the rolling coating of the plate is completed, the conveyor belt 2 with the fault is repaired to reduce the impact on the rolling coating of the plate, thereby improving the applicability of the two slide bars 24 and the sleeve bar 18.

[0054] If some plates need to be double-sided roller coated, after the plates are normally roller coated on one side and fall on the top of the unloading plate 38, the plates are driven downward for a distance by the unloading plate 38, so that the two first sliders 23 can drive the two slide bars 24 and the sleeve bar 18 to move to the rightmost end of the two limit bars 6 inside the corresponding first chute 22, and then the plates are driven upward to a position flush with the top of the conveyor belt 2 by the unloading plate 38. At this time, by controlling the two first sliders 23 to move toward the left end inside the corresponding first chute 22, the two slide bars 24 and the sleeve bar 18 can be driven to move toward the left end together;

[0055] After the plate is pushed to the top of the right end of the conveyor belt 2 for placement, the conveyor belt 2 is controlled to reverse, and the telescopic ends of the multiple electric telescopic rods 12 are controlled to move upward together, and the two shells 3 are pushed to move upward to a position away from the plate. As the conveyor belt 2 reverses, the plate is driven to move to the left end and falls on the top of the plate stacked on the top of the two placement plates 8. After the two rotating rods 19 are controlled to rotate downward together to a horizontal state, as the sleeve rod 18 and the two sliding rods 24 continue to move toward the left end, the plate that has been processed once and placed on the top of the multiple plates that have not been processed can be pushed to the top of the two rotating rods 19 for placement. At this time, the two clamping plates 34 are respectively located at the center position on both sides of the plate, and the telescopic ends of the two electric push rods 33 are controlled to extend together, driving the two clamping plates 34 to clamp and fix the two sides of the plate, and after the two third sliding blocks 32 are controlled to move upward together to a specified height inside the corresponding third slide groove 31, the fourth driving device inside the two third sliding blocks 32 is controlled to drive and rotate the two electric push rods 33, driving the two clamping plates 34 and the clamped plate to flip 180 degrees together;

[0056] Subsequently, the two third sliding blocks 32 can be moved downward and reset inside the corresponding third sliding grooves 31, driving the flipped plate to fall on the top of the two rotating rods 19 again, and by controlling the two rotating rods 19 to continue to rotate upward, the plate can slide on the top of multiple unprocessed plates and be placed, and move toward the right end with the help of the two sliding rods 24 and the sleeve rod 18, and push it to fall on the top of the conveyor belt 2 again. With the forward rotation of the conveyor belt 2 and the downward movement and reset of the telescopic ends of the multiple electric telescopic rods 12, the plate can be rolled for the second time, and the double-sided rolling coating of the plate can be completed, so that the device can roll-coat the double-sided plate during actual use, further improving the applicability of the device during actual use.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
