Description

Technical Field

[0001] The present application relates to the field of the structure of a paper pasting machine, and in particular to a cleaning device for a grooved rubber roller of a paper pasting machine. Background Art

[0002] A paper pasting machine coats glue between two sheets of paper, and then applies pressure to bond the two sheets of paper. In the process of coating glue onto the paper, a rubber roller is generally used. And in order to enhance the friction between the paper and the rubber roller and improve the uniformity of glue coating, specific grooves are generally formed on the surface of the rubber roller to form a grooved rubber roller.

[0003] During the long-term use of the grooved rubber roller, glue is likely to solidify in the grooves on its surface, affecting the glue coating performance that the grooved rubber roller can achieve. For this reason, it is necessary to clean the glue on the surface and in the grooves of the grooved rubber roller. For example, a cleaning device for gluing a paper pasting machine with the publication number of CN221457193U uses a cleaning ring sleeved on the grooved rubber roller to move, so that the cleaning blocks arranged on the cleaning ring can be embedded into the grooves of the grooved rubber roller to scrape the solidified glue out of the grooves, and cooperate with a cleaning brush to fully clean the surface of the grooved rubber roller.

[0004] Regarding the above related technologies, the grooves on the surface of the grooved rubber roller are in various forms, such as spiral or arc-shaped. The method of using a cleaning block to move in the groove to scrape off the solidified glue has a small scope of application. Summary of the Invention

[0005] In order to be applicable to the cleaning of glue in the grooves of different grooved rubber rollers, the present application provides a cleaning device for a grooved rubber roller of a paper pasting machine.

[0006] The cleaning device for a grooved rubber roller of a paper pasting machine provided by the present application adopts the following technical solutions.

[0007] A cleaning device for a grooved rubber roller of a paper pasting machine includes a frame, two groups of roller sliders slidably connected to the frame, a rubber roller rotatably connected to the two groups of roller sliders one by one and having grooves on its surface, a rubber roller motor arranged on the roller slider to drive the rubber roller to rotate, a roller slider cylinder arranged on the frame to drive the roller slider to approach or move away from the paper to be coated with glue, a box frame slidably connected to the frame, a box frame cylinder arranged on the frame to drive the box frame to move, a cleaning box slidably connected to the box frame and containing cleaning liquid inside and allowing the bottom of the rubber roller to enter, and a box cylinder arranged on the box frame to drive the cleaning box to move along the direction of the power rod of the roller slider cylinder. The direction of the power rod of the box frame cylinder is perpendicular to the direction of the power rod of the box cylinder.

[0008] By adopting the above technical solution, after a certain period of use of a rubber roller, before the glue in the groove on the surface of the rubber roller is expected to solidify, the corresponding rubber roller is stopped from being used and cleaned in time with a cleaning liquid, and the other rubber roller is used to apply glue to the paper. On the one hand, it can be more widely applicable to rubber rollers with different grooves, and at the same time, it is not easy to have a greater impact on the progress of the glue application operation on the paper.

[0009] Optionally, liquid blocking plates are rotatably connected to both opposite sides of the opening of the cleaning box for the rubber roller to enter. The cleaning box is provided with a liquid blocking plate motor for driving the liquid blocking plate to rotate. The height of the side of the liquid blocking plate away from its rotation point can be higher than the upper height of the rubber roller, and the sides of the two liquid blocking plates away from their respective rotation points can approach or abut against each other.

[0010] By adopting the above technical solution, during the rotation of the lower part of the rubber roller in the cleaning box, a part of the cleaning liquid may be carried out and splashed by the rotating rubber roller. Therefore, after the lower part of the rubber roller enters the cleaning box, the two liquid blocking plates rotate to surround the upper part of the rubber roller. Even when the rubber roller rotates at a relatively high speed, it is not easy for a large amount of cleaning liquid to splash out, so as to avoid contaminating the paper.

[0011] Optionally, two belt rollers are rotatably connected to the liquid blocking plate, and the two belt rollers are drivingly connected to a cleaning belt that is transmitted along the axial direction of the rubber roller. A belt roller motor for driving the belt roller to rotate is provided on the side of the liquid blocking plate away from the rubber roller, and sponge blocks are fixedly connected to the surface of the cleaning belt.

[0012] By adopting the above technical solution, during the rotation of the rubber roller, the sponge blocks will also closely wipe the rubber roller. The sponge blocks can deform and enter the grooves on the surface of the rubber roller to remove the glue in the grooves of the rubber roller faster, without waiting for the rubber roller to rotate for a long time before the cleaning liquid can fully wash away the glue in the grooves of the rubber roller, improving the cleaning efficiency and quality in the grooves of the rubber roller.

[0013] Optionally, the liquid blocking plate is provided with a plate groove for the belt roller to rotate in, and convex strips are fixedly connected in the plate groove. The sponge blocks can enter the plate groove and deform when passing through the convex strips.

[0014] By adopting the above technical solution, after the sponge blocks complete one wipe of the rubber roller, the sponge blocks will enter the plate groove and then pass through several convex strips, so that the mixed liquid of the cleaning liquid and glue absorbed by the sponge blocks can be squeezed out. The squeezed sponge blocks will then wipe the rubber roller again, and so on, to clean the surface and grooves of the rubber roller with higher efficiency.

[0015] Optionally, liquid outlet valves are communicated with both the bottom and the top of the cleaning box. The liquid outlet valves are communicated with sampling tubes, and the cleaning box is communicated with a drain pipe for sending out the cleaning liquid and a liquid supply pipe for pumping the cleaning liquid in.

[0016] By adopting the above technical solution, the quality of the cleaning liquid can be sampled at any time to observe whether it is turbid or in other conditions, so that the cleaning liquid that has been used for a long time and has become ineffective can be replaced in time.

[0017] Optionally, a box filter located above one end of the drain pipe connected to the cleaning box is detachably connected to the inside of the cleaning box.

[0018] By adopting the above technical solution, when the sponge block is in contact with the surface of the rotating rubber roller for wiping, some sponge crumbs are easily generated, and the box filter can block the sponge crumbs to prevent them from entering the drain pipe.

[0019] Optionally, the cleaning box is detachably connected to drying boxes on opposite sides, and a hot air nozzle capable of delivering heated airflow to the surface of the rubber roller is provided in the drying box, and the hot air nozzle blows out hot air in an inclined downward direction.

[0020] By adopting the above technical solution, the cleaning box will be away from the rubber roller for a predetermined cleaning time, and the drying box can be moved to the lower part of the rubber roller, and during the movement, the liquid baffle plate can receive the cleaning liquid dripping from the rubber roller, so that the cleaning liquid is not easy to fall on the connection between the drying box and the cleaning box. Afterwards, the hot air nozzle can blow hot air downward to dry the surface of the rubber roller and the groove more quickly, and also make it difficult for the hot air to blow the cleaning liquid away from the drying box, so as to prevent the blown-away cleaning liquid from falling at will.

[0021] Optionally, the hot air nozzle is rotatably connected to the inner wall of the drying box, the rotation axis of the hot air nozzle is perpendicular to the axis of the rubber roller, the hot air nozzles are arranged in a row on opposite sides of the drying box, the hot air nozzles in the same row are rotatably connected to the same driving rod, the drying box is detachably connected to a reciprocating electric cylinder, the reciprocating electric cylinder power rod is detachably connected to a synchronous part, both ends of the synchronous part are formed with waist grooves, the end of the driving rod is fixedly connected to a guide column slidably connected to the waist groove, and the sliding direction of the guide column in the waist groove is perpendicular to the moving direction of the reciprocating electric cylinder power rod.

[0022] By adopting the above technical solution, the two rows of hot air nozzles swing within a certain range, so that a more sufficient drying effect is obtained on the surface of the rubber roller and in the groove.

[0023] Optionally, the bottom surface of the drying box is connected to a liquid return pump, the liquid outlet of the liquid return pump is connected to the cleaning box, and the inner wall of the drying box is provided with a liquid level sensor capable of detecting the liquid level in the drying box.

[0024] By adopting the above technical solution, the cleaning liquid dripping from the rubber roller in the drying box will accumulate after long-term use. When the accumulated liquid in the drying box reaches a certain height, the accumulated cleaning liquid is returned to the cleaning box to prevent excessive cleaning liquid in the drying box and to recover and reuse the cleaning liquid.

[0025] Optionally, the cleaning box is provided with a heat-conducting pipe through which the heated fluid circulates to heat the cleaning liquid.

[0026] By adopting the above technical solution, the cleaning liquid is heated so that the glue can be better dissolved in the cleaning liquid.

[0027] In summary, the present application includes at least the following beneficial effects.

[0028] After a rubber roller has been used for a certain period of time, and before the grooves on the surface of the rubber roller are expected to solidify, the corresponding rubber roller will be stopped from use and cleaned with cleaning fluid in time, and another rubber roller will be used to apply glue to the corresponding paper. This can be more widely used for rubber rollers with different grooves, and it is not easy to have a significant impact on the progress of the paper gluing operation.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application embodiment discloses a cleaning device for a slotted rubber roller of a paper mounting machine, referring to Figure 1, including a frame 1 located on the ground. Two adjacent vertical sides of the frame 1 are each slidably connected with a roller slider 2 in the vertical direction. There are two sets of roller sliders 2, with two in each set. The two roller sliders 2 in the same set are slidably connected to the two adjacent vertical sides of the frame 1 in a one-to-one correspondence. The frame 1 is detachably connected with a roller slider cylinder 5 corresponding to each roller slider 2. The power rod of the roller slider cylinder 5 is detachably connected to the upper part of the roller slider 2. A rubber roller 3 is rotatably connected between the two roller sliders 2 in the same set. When one rubber roller 3 has been used for a certain period of time, it moves upward, and the other rubber roller 3 moves downward to quickly start the gluing operation of the paper. At the same time, the roller slider 2 is detachably connected with a rubber roller motor 4, and the rubber roller motor 4 drives the rubber roller 3 to rotate via a reduction gearbox.

[0033] Refer to Figure 1 and Figure 2 , the frame 1 is slidably connected with a box frame 51 in the horizontal direction. The bottom of the frame 1 is provided with a slide rail for the box frame 51 to slide. The frame 1 is detachably connected with a box frame cylinder 35 whose power rod is detachably connected to the box frame 51. The box frame 51 is detachably connected with a box cylinder 32 whose power rod is vertical. The upper end of the power rod of the box cylinder 32 is detachably connected with a cleaning box 52. The length direction of the cleaning box 52 is consistent with the axis direction of the rubber roller 3. The cleaning box 52 can move to directly below the rubber roller 3 that has moved upward after being used for a certain period of time, and the lower part of the rubber roller 3 can enter the cleaning box 52 to come into contact with the cleaning liquid.

[0034] Refer to Figure 2 and Figure 3 , one end of the length direction of the cleaning box 52 is connected with two liquid outlet valves 36 that can be solenoid valves. The two liquid outlet valves 36 are both connected with a sampling pipe 31. The two liquid outlet valves 36 are located at the upper and lower parts of the cleaning box 52 in a one-to-one correspondence, so as to sample the cleaning liquid in the cleaning box 52 with a certain height to check whether it has failed. The side of the cleaning box 52 where the liquid outlet valve 36 is provided is connected with a drain pipe 33 and a liquid supply pipe 34. The drain pipe 33 pumps out the cleaning liquid and the liquid supply pipe 34 pumps the cleaning liquid. The height of the drain pipe 33 is lower than the height of the liquid supply pipe 34. In addition, a heat conduction pipe 45 is arranged inside the cleaning box 52, and a heat conduction fluid with a relatively high temperature circulates inside the heat conduction pipe 45, so that the cleaning liquid in the cleaning box 52 is heated to a certain temperature to improve the cleaning effect on the glue.

[0035] Refer to Figure 2, liquid baffle plates 53 are rotatably connected to both sides of the upper opening of the cleaning box 52 in the length direction. The cleaning box 52 is detachably connected to a liquid baffle motor 54 whose output shaft is coaxially and detachably connected to the rotation point of the liquid baffle plate 53. When the cleaning box 52 is lifted to a predetermined height, the two liquid baffle plates 53 rotate and the upper parts of the two liquid baffle plates 53 approach or abut against each other, so that the rotating rubber roller 3 is not easily splashed out with the cleaning liquid. Plate grooves 48 are formed on the surfaces of the two liquid baffle plates 53 facing the rubber roller 3. A set of two belt rollers 46 are rotatably connected in the two plate grooves 48. The two belt rollers 46 of the same group are drivingly connected to a cleaning belt 55. A belt roller motor 47 is detachably connected to the surface of the liquid baffle plate 53 facing away from the rubber roller 3. The belt roller motor 47 drives a corresponding belt roller 46 to rotate through a reduction gearbox. A plurality of sponge blocks 56 are fixedly connected to the surface of the cleaning belt 55 along its driving direction. The sponge blocks 56 will closely adhere to the upper part of the rubber roller 3 when the liquid baffle plate 53 finishes flipping, and the cleaning belt 55 drives along the axis direction of the rubber roller 3, so that the sponge blocks 56 can more fully remove the glue on the surface and in the grooves of the rubber roller 3.

[0036] Refer to Figure 1 and Figure 2 , a plurality of ridges 49 are fixedly connected in the plate groove 48 along the length direction of the cleaning box 52. The sponge block 56 can enter the plate groove 48 and be squeezed when passing through the ridge 49, so that the cleaning liquid adsorbed on the surface of the rubber roller 3 wiped by the sponge block 56 can be squeezed out. In addition, a horizontal box filter screen 21 is detachably connected in the cleaning box 52. The height of the box filter screen 21 is higher than the height of the end of the drain pipe 33 communicating with the cleaning box 52, so that the sponge scraps generated during the process of the sponge block 56 wiping the rubber roller 3 or passing through the ridge 49 are not easily introduced into the drain pipe 33.

[0037] Refer to Figure 2 and Figure 4, drying boxes 57 are detachably connected to the vertical outer walls on both sides in the length direction of the cleaning box 52. The length direction of the drying box 57 is consistent with the length direction of the cleaning box 52. After the drying box 57 moves to a predetermined position, the lower part of the rubber roller 3 that has been cleaned will be located inside the drying box 57. A row of hot air nozzles 58 are rotatably connected to the two vertical inner walls in the length direction inside the drying box 57. The hot air nozzles 58 are connected to an external air compressor and an air electric heater through hoses, so that the hot air nozzles 58 can send hot air towards the rubber roller 3. The air supply direction of the hot air nozzles 58 is inclined downward and sends hot air towards the lower part of the rubber roller 3, so that the hot air is not likely to carry out the cleaning liquid on the surface of the rubber roller 3 out of the drying box 57. The same driving rod 59 is rotatably connected to the inclined lower surface of each row of hot air nozzles 58. A guide post 44 is fixedly connected to the end of the driving rod 59. A synchronizing member 42 is installed at the adjacent ends of the two driving rods 59. A waist slot 43 for the guide post 44 to slide inside is provided on the surface of the synchronizing member 42. The straight line where the sliding direction of the guide post 44 in the waist slot 43 is located is within the inclined plane formed during the rotation of the hot air nozzles 58. A reciprocating electric cylinder 41 is detachably connected to the end of the drying box 57. The power rod of the reciprocating electric cylinder 41 passes through the drying box 57 along the length direction of the drying box 57 and is detachably connected to the synchronizing member 42, so that the reciprocating electric cylinder 41 can drive the two rows of hot air nozzles 58 to rotate reciprocally within a fan-shaped area.

[0038] Referring to Figure 2 and Figure 3 , a liquid return pump 39 is detachably connected and communicated at the bottom of one end face in the length direction of the drying box 57. The liquid outlet of the liquid return pump 39 is connected to the upper part of the cleaning box 52 through a pipeline. At the same time, a liquid level sensor 37 is detachably connected inside the drying box 57. The liquid level sensor 37 and the liquid return pump 39 are electrically connected to an external controller. When the liquid level sensor 37 detects that the liquid level height of the cleaning liquid in the drying box 57 is higher than the preset liquid level height in the external controller, the liquid return pump 39 pumps the cleaning liquid in the drying box 57 into the cleaning box 52.

[0039] The implementation principle of the cleaning device for the slotting rubber roller of the paper pasting machine in the embodiment of the present application is as follows: When a rubber roller 3 is used for a certain period of time, the corresponding roller slider cylinder 5 drives the corresponding rubber roller 3 to move upward, and the other rubber roller 3 moves downward for watering and coating operations. Then the box frame cylinder 35 drives the cleaning box 52 to translate to directly below the rubber roller 3 that has been used for a certain period of time. The power rod of the box cylinder 32 extends again so that the cleaning box 52 moves upward to a predetermined height, so that the lower part of the rubber roller 3 is located in the cleaning liquid. Then the baffle motor 54 drives the baffle 53 to rotate, so that the sponge block 56 fits on the surface of the rubber roller 3. Then the rubber roller 3 rotates, and the sponge block 56 moves along the axis of the rubber roller 3 to clean the rubber roller 3.

[0040] After the cleaning for the set duration is completed, the cassette rack 51 moves downward and then translates to the middle position between the two rubber rollers 3, so that a drying cassette 57 is directly opposite to the lower part of the rubber roller 3 after cleaning. Then the drying cassette 57 moves upward, so that the lower part of the rubber roller 3 is located inside the drying cassette 57. Then while the rubber roller 3 rotates, the hot air nozzle 58 sends hot air to the lower part of the rubber roller 3, and at the same time, the reciprocating electric cylinder 41 drives each hot air nozzle 58 to rotate within the fan-shaped area to achieve the drying of the rubber roller 3. After the drying is completed, the cassette rack 51 returns to its original position.

[0041] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
