[0062] As Figures 1 - 13 shown, the present utility model provides a printing machine 1000, which helps to solve the problem of poor cleaning effect existing in the use of the existing printing machine 1000.

[0063] In terms of the overall design, the printing machine 1000 includes a frame 100, a conveying system 200, and a cleaning device 300. Among them, the conveying system 200 is arranged on the frame 100. The conveying system 200 includes a guide belt 25, the guide belt 25 has a working surface 251 arranged in a first direction, and a first cleaning surface arranged in a second direction. There is a first included angle between the first direction and the second direction, and the first included angle is an acute angle. The cleaning device 300 includes a cleaning assembly 30. The cleaning assembly 30 is movably arranged on the frame 100. The cleaning assembly 30 has a flushing joint 32, a first cleaning member 33, a brush roller 34, a first scraper 35, and a second cleaning member 36 arranged in sequence along the second direction. Moreover, the first cleaning member 33, the brush roller 34, the first scraper 35, and the second cleaning member 36 can all be in contact with the cleaning surface.

[0064] Specifically, by defining that the guide belt 25 has a first cleaning surface, and this first cleaning surface can cooperate with the cleaning assembly 30 to realize multiple operations such as flushing, brushing, and scraping, thereby realizing the cleaning work of the guide belt 25. The structure is simple, the operation is convenient, and the cleaning effect is good. At the same time, by defining that the cleaning assembly 30 can be movable on the frame 100, effective regulation of the cleaning of the guide belt 25 can be realized, so that the cleaning time can be controlled as needed. Moreover, by defining that the cleaning surface is arranged in the second direction, and the second direction forms an acute angle with the first direction (horizontal direction), the first cleaning surface is arranged obliquely as a whole. Cooperating with the arrangement of each component in the cleaning assembly 30, it helps to reduce the splashing of the cleaning liquid and the collection of the cleaning liquid, thereby further improving the cleaning effect.

[0065] It should be understood that the printing machine 1000 includes a frame 100, a conveying system 200, and a cleaning device 300. In this embodiment, the frame 100 is generally in the shape of a cuboid. Among them, the frame 100 has two spaced-apart mounting plates 11, and the two mounting plates 11 are connected together by a number of connecting rods 12. At the same time, both the conveying system 200 and the cleaning device 300 are arranged between the two mounting plates 11.

[0066] It should be further understood that the conveying system 200 includes a driving roller 21, a driven roller 22, an adjusting roller, and a guide belt 25. The driving roller 21, the driven roller 22, and the adjusting roller are all of tubular structures, and the guide belt 25 is sleeved on the driving roller 21, the driven roller 22, and the adjusting roller. Specifically, both ends of the driving roller 21, the driven roller 22, and the adjusting roller are inserted through the two mounting plates 11, and the driving roller 21, the driven roller 22, and the adjusting roller are all connected to the frame 100 through bearings to ensure that the driving roller 21, the driven roller 22, and the adjusting roller can rotate around their own axes.

[0067] Further, the adjusting roller includes a fixed deviation correcting roller 23 and a movable deviation correcting roller 24. The fixed deviation correcting roller 23 and the movable deviation correcting roller 24 are both parallel to the driving roller 21. The driving roller 21, the driven roller 22, the fixed deviation correcting roller 23, and the movable deviation correcting roller 24 are distributed in a quadrilateral shape, and the guide belt 25 is formed with a working surface 251, a first cleaning surface 252, a second cleaning surface 253, and a gluing surface 254.

[0068] Specifically, by defining that the adjusting roller includes a fixed deviation correcting roller 23 and a movable deviation correcting roller 24, the deviation of the guide belt 25 can be effectively prevented, and by adjusting the movable deviation correcting roller 24, the guide belt 25 can be kept in a straight state, thereby ensuring the smoothness of the medium transmission. At the same time, the arrangement of the movable deviation correcting roller 24 and the fixed deviation correcting roller 23 changes the guide belt 25 below the driving roller 21 and the driven roller 22 from one surface to three surfaces. And by adjusting the movable deviation correcting roller 24 and the fixed deviation correcting roller 23, the gluing surface 254 can be adjusted so that the gluing surface 254 is tangent to the first roller body to achieve the gluing work.

[0069] It should be further understood that the fixed deviation correcting roller 23 and the movable deviation correcting roller 24 are rotatably arranged between two mounting plates 11, and along the second direction b, the driving roller 21, the movable deviation correcting roller 24, the fixed deviation correcting roller 23, and the driven roller 22 are arranged in sequence. The distance between the driving roller 21 and the driven roller 22 is greater than the distance between any other two rollers. By arranging the driving roller 21 and the driven roller 22, one on the left and one on the right, above the fixed deviation correcting roller 23 and the movable deviation correcting roller 24, and the fixed deviation correcting roller 23 and the movable deviation correcting roller 24 are also arranged, one on the left and one on the right, below the driving roller 21 and the driven roller 22, not only can the movable deviation correcting roller 24 correct the running direction of the guide belt 25 in real time through the deviation correcting device to ensure the continuous and stable progress of the printing work, but also ensure the image quality of the printing. Moreover, it also has a certain error compensation effect, making the guide belt 25 not easy to deviate during operation. At the same time, it is also convenient to correct the guide belt 25 when it deviates.

[0070] Further, the conveying system 200 further includes a driving device 26. The driving device 26 is arranged on the frame 100, and the output end of the driving device 26 is in transmission connection with the movable deviation correcting roller 24.

[0071] Specifically, by setting the driving device 26, the movable deviation correcting roller 24 can be effectively driven to move, thereby adjusting the extending direction of the second cleaning surface 253. It not only has a simple structure and is convenient for assembly, but also can cooperate with other components to realize the automatic control of the printing machine 1000 and improve the use effect of the printing machine 1000.

[0072] It should be understood that in this embodiment, both ends of the fixed deviation rectifying roller 23 are respectively connected to two mounting plates 11 through bearings. At the same time, driving devices 26 are arranged on both mounting plates 11, and a movable plate is fixedly installed at the output end of the driving device 26. The two movable plates are connected to both ends of the movable deviation rectifying roller 24 through bearings. At this time, when the two driving devices 26 work simultaneously, the position of the movable deviation rectifying roller 24 can be effectively adjusted, thereby changing the extension direction of the second cleaning surface 253 to facilitate the cleaning of the cleaning liquid on the second cleaning surface 253.

[0073] Furthermore, the cleaning assembly 30 includes a housing 31. A first cleaning member 33, a brush roller 34, a first scraper 35, and a second cleaning member 36 are rotatably arranged in the housing 31, and a sewage discharge pipe 313 is arranged on the housing 31.

[0074] Specifically, by providing the housing 31, it can not only provide an installation basis for the first cleaning member 33, the brush roller 34, the first scraper 35, and the second cleaning member 36, effectively collect the cleaning liquid sprayed by the flushing joint 32, reduce the impact of the cleaning liquid on the printing machine 1000, but also effectively reduce the splashing of the cleaning liquid, thereby improving the use effect of the cleaning assembly 30. Moreover, the setting of the housing 31 can also cooperate with the following driving assembly 40 to realize the movement of the cleaning assembly 30, which helps to improve the control effect of cleaning the guide belt 25.

[0075] As Figure 3 and Figure 6 shown, the housing 31 is movably arranged on the frame 100. Inside the housing 31, a flushing joint 32, a first cleaning member 33, a brush roller 34, a first scraper 35, and a second cleaning member 36 are sequentially arranged along the second direction. Among them, the flushing joint 32 is communicated with an external cleaning liquid supply device to be able to provide high-pressure water flow, so as to be able to perform preliminary cleaning on the guide belt 25, and cooperate with the first cleaning member 33 to collect the cleaning liquid output by the flushing joint 32 and scrub the guide belt 25. The first cleaning member 33 can absorb the cleaning liquid output by the flushing joint 32 and scrub the guide belt 25 in cooperation with the cleaning liquid. The brush roller 34 can effectively brush the surface of the guide belt 25 to remove glue and impurities, or loosen the connection effect between the glue and the guide belt 25. Cooperating with the following first scraper 35 can effectively remove the glue and impurities. At this time, the second cleaning member 36 can further scrub the first cleaning surface 252 of the guide belt 25 to complete the cleaning of the guide belt 25. In addition, a sewage discharge pipe 313 is arranged at the bottom of the housing 31 to be able to discharge the impurities and the cleaning liquid output by the flushing joint 32.

[0076] Further, the printing machine 1000 further includes a driving assembly 40, and the driving assembly 40 includes a guide rail 41 and a first driving member 43. Among them, the guide rail 41 is arranged on the frame 100, and the guide rail 41 is slidably connected to the bin body 31. The first driving member 43 is arranged on the frame 100, and the output end of the first driving member 43 is connected to the bin body 31 to move the bin body 31 in the first direction.

[0077] Specifically, by setting the driving assembly 40 to be connected to the bin body 31, the movement of the bin body 31 can be effectively controlled, and further, the contact between the first cleaning member 33, the brush roller 34, the first scraper 35 and the second cleaning member 36 and the guide belt 25 can be controlled, so as to realize the automatic control of the cleaning of the guide belt 25. At the same time, by setting the guide rail 41 to be slidably connected to the bin body 31, not only can the bin body 31 be guided, but also the bin body 31 can be installed and fixed on the frame 100.

[0078] It should be understood that the number of the guide rails 41 is two, and the two guide rails 41 are respectively arranged on the two mounting plates 11. Two rollers 42 are slidably arranged inside any one of the guide rails 41, and the rollers 42 are rotatably connected to the bin body 31 to enable the bin body 31 to move on the guide rail 41. In this embodiment, the first driving member 43 is set as a cylinder. The first driving member 43 is arranged on the mounting plate 11, and the output end of the first driving member 43 is connected to the bin body 31 to move the bin body 31 in the first direction.

[0079] Further, the bin body 31 has a first cavity 311 and a second cavity 312. The first cleaning member 33, the brush roller 34, and the first scraper 35 are all arranged in the first cavity 311, and the second cleaning member 36 is arranged in the second cavity 312.

[0080] Specifically, since the flushing joint 32, the first cleaning member 33, the brush roller 34, the first scraper 35, and the second cleaning member 36 are arranged on one side in the second direction, and the second direction is inclined, therefore, the cleaning liquid output by the flushing joint 32 is likely to flow to the second cleaning member 36 after passing through the first cleaning member 33 and the brush roller 34. And at this time, the cleaning liquid is relatively turbid, which is likely to contaminate the second cleaning member 36 and adhere to the guide belt 25 along with the second cleaning member 36. Therefore, by dividing the bin body 31 into the first cavity 311 and the second cavity 312, the cleaning liquid can be separately treated, thereby reducing the secondary pollution of the guide belt 25.

[0081] It should be understood that the bin body 31 includes a first cavity 311 and a second cavity 312 arranged in sequence along the second direction. At the same time, sewage pipes 313 are arranged at the bottoms of both the first cavity 311 and the second cavity 312, and the two sewage pipes 313 can be separately arranged or connected together, but the connection part of the two is not higher than the sewage outlet of the second cavity 312. Preferably, the above-mentioned flushing joint 32 is arranged inside the first cavity 311, and a water baffle is arranged on the first cavity 311, and the water baffle can effectively prevent the cleaning liquid output by the flushing joint 32 from splashing. In this embodiment, the water baffle is an organic glass plate made of transparent material.

[0082] Furthermore, the cleaning assembly 30 further includes a partition plate, which is arranged in the first cavity 311, located between the first cleaning member 33 and the brush roller 34, and divides the bin body 31 into a first part 3111 and a second part 3112.

[0083] Specifically, by arranging a partition plate between the first cleaning member 33 and the brush roller 34 and dividing the bin body 31 into a first part 3111 and a second part 3112, it can effectively prevent sewage from entering the lower brush roller 34, thereby effectively reducing the occurrence of secondary pollution and helping to further improve the cleaning effect.

[0084] Still as Figure 6 shown, the flushing joint 32 and the first cleaning member 33 are both arranged in the first part 3111, and the brush roller 34 and the first scraper 35 are both arranged in the second part 3112. With this arrangement, it can cooperate with the above-mentioned second cavity 312 to divide the bin body 31 into three parts, thereby ensuring the output of three different degrees of sewage, further helping to reduce the secondary pollution of sewage and ensuring the cleaning effect. At the same time, another flushing joint 32 is also arranged between the brush roller 34 and the first scraper 35. On the one hand, this flushing joint 32 can wash away part of the stains or glue, and on the other hand, it can also assist the first scraper 35 to realize the cleaning of the guide belt 25.

[0085] In this embodiment, the flushing joint 32 is tubular, and spray holes are arranged on the circumferential surface of the flushing joint 32. The number of spray holes is multiple, and the multiple spray holes are arranged at intervals along the axial direction of the flushing joint 32. The structure is simple and the flushing effect is good.

[0086] At this time, the first cleaning member 33 includes a cleaning roller 331 and a squeezing roller 332. Among them, the cleaning roller 331 is rotatably arranged in the bin body 31, and the squeezing roller 332 is fixedly arranged on one side of the cleaning roller 331. In this embodiment, the cleaning roller 331 is a water-absorbing member. Preferably, the cleaning roller 331 is a sponge roller. The sponge roller can absorb the cleaning liquid output by the flushing joint 32 and cooperate with the cleaning liquid to scrub the guide belt 25. The squeezing roller 332 is a rigid member, and the squeezing roller 332 abuts against the cleaning roller 331 and can squeeze the cleaning liquid in the cleaning roller 331 into the bin body 31.

[0087] It should be noted that, in addition to being set as a sponge roller, the cleaning roller 331 can also be set to other structures as long as it can quickly absorb the cleaning liquid.

[0088] In this embodiment, the brush roller 34 includes a roller body and bristles arranged on the surface of the roller body to be able to brush the residual glue or impurities on the guide belt 25. At the same time, the second cleaning surface of the guide belt 25 moves in the second direction, and the arrow direction b in the figure is the second direction. When the first cleaning member 33 contacts the guide belt 25, the above-mentioned cleaning roller 331 rotates counterclockwise under the drive of the guide belt 25, while the brush roller 34 moves clockwise under the action of an external drive structure to be able to further improve the cleaning effect on the guide belt 25. Combining Figure 4 and Figure 5 As shown, a drive motor 90 is arranged on the frame 100, and the output shaft of the drive motor 90 is connected to the brush roller 34 through a conveyor belt 91. Preferably, the drive motor 90 is arranged on one side of the mounting plate 11, and both the output shaft of the drive motor 90 and one end of the brush roller 34 pass through the mounting plate 11 and are respectively provided with guide wheels, and the conveyor belt 91 is sleeved on the guide wheels to be able to ensure the clockwise rotation of the brush roller 34, with a simple structure and helpful for ensuring the cleaning effect of brushing.

[0089] It should be noted that both ends of the first scraper 35 are fixed on the bin body 31, and the extending direction of the first scraper 35 is perpendicular to the second direction. At the same time, the first scraper 35 is an existing product and will not be elaborated here.

[0090] It needs to be further understood that the second cleaning member 36 has the same structure as the first cleaning member 33, and the number of the second cleaning members 36 is two, and the two second cleaning members 36 are arranged at intervals along the second direction.

[0091] It should be pointed out that using two second cleaning members 36 can further improve the cleaning effect on the cleaning surface of the guide belt 25, avoid the residue of stains, and effectively discharge the above-mentioned residual sewage, so as to cooperate with the following baking assembly 70 to reduce the influence of sewage on the subsequent gluing.

[0093] Specifically, by defining the extending direction of the second cleaning surface, an inclined surface can be formed. At this time, the position where the fixed deviation correction shaft is located is the lowest point of the guide belt 25. Since there is partial water stain on the guide belt 25 after passing through the first cleaning surface 252, setting the second cleaning surface inclined at this time can further improve the cleaning effect. At the same time, defining the angular value of the second included angle to be smaller than that of the first included angle can better cooperate with the following cooperation of the rubber scraping assembly 50 and the baking assembly 70 to ensure the cleaning effect.

[0094] It should be understood that the rubber scraping assembly 50 includes a main body 51 and a second scraper 52. The structure of the main body 51 is a cuboid structure with an open top, and the second scraper 52 is fixedly arranged on the main body 51. At the same time, a second driving member 60 is arranged on the frame 100. The number of the second driving members 60 is two, and they are respectively connected to both ends of the main body 51, so as to drive the second scraper 52 to move and be tangent to the second cleaning surface 253 of the guide belt 25.

[0095] It should be noted that the rubber scraping assembly 50 has a receiving cavity to be able to receive stains and sewage, and a discharge port is arranged at the bottom of the receiving cavity, so as to ensure the use effect of the rubber scraping assembly 50.

[0096] Further, the cleaning device 300 further includes a blower assembly 80. The blower assembly 80 has an output port 821 opened along a fourth direction. There is a third included angle between the fourth direction and the third direction, and the third included angle is an obtuse angle.

[0097] As Figure 9 and Figure 10 shown, the blower assembly 80 has a mounting member 81, a pipe body 82 and an output port 821 arranged on the pipe body 82. Among them, the mounting member 81 can be fixedly arranged on the frame 100. The pipe body 82 is a cylinder as a whole. One end of the pipe body 82 is communicated with an external blower. An output port 821 is opened on the circumferential surface of the pipe body 82. The orientation of the output port 821 and the second cleaning surface 253 are arranged at an obtuse angle as a whole, which helps to further increase the contact area between the air flow and the second cleaning surface 253 and ensure the contact effect.

[0098] Further, the cleaning device 300 further includes a plurality of baking assemblies 70. The baking assemblies 70 are arranged at intervals with the guide belt 25, and at least one baking assembly 70 faces the second cleaning surface 253.

[0099] Specifically, by providing the baking assembly 70, the water stains on the conveyor belt 25 can be further removed, ensuring the dryness of the surface of the conveyor belt 25, so as not to affect the subsequent gluing operation. The number of the baking assemblies 70 can be one or more, and multiple baking assemblies 70 can improve the baking effect and ensure cleanliness. At the same time, it is specified that at least one baking assembly 70 is arranged facing the second cleaning surface 253, which can cooperate with the fan assembly 80 to achieve a further drying and cleaning effect.

[0100] As Figures 11 - 13 shown, the baking assembly 70 includes a box body 71, a fan 72, ventilation holes 73 and a heating element 74. Among them, the box body 71 is integrally in a cuboid structure, and both ends are fixedly arranged on two mounting plates 11 respectively. At the same time, a plurality of fans 72 are arranged on one side of the box body 71, and the plurality of fans 72 are arranged in sequence. A heating element 74 is arranged inside the box body 71 to be able to heat the air. A plurality of ventilation holes 73 are arranged on the side of the box body 71 away from the fan 72. External air can enter the inside of the box body 71 through the fan 72 and thus be heated by the heating element 74 to form hot air, and under the action of the fan 72, it is output from the ventilation holes 73 and blown towards the second cleaning surface 253.

[0101] It should be noted that the installation position of the baking assembly 70 is arranged on the output side of the fan assembly 80 or the glue scraping assembly 50 along the moving direction of the conveyor belt 25. And at this time, the ventilation holes 73 of the baking assembly 70 can be arranged facing the second cleaning surface 253 or the gluing surface 254. At this time, it should be noted that when the ventilation holes 73 of the baking assembly 70 are arranged facing the gluing surface 254, the baking assembly 70 is located between the fan assembly 80 and the gluing device. Such an arrangement is to enable the drying work of the baking assembly 70 to be completed before the conveyor belt 25 comes into contact with the glue paste, so as to avoid affecting the gluing work.
