Description

Technical Field

[0001] The utility model relates to the field of printing machines, in particular to a printing machine with the function of preventing ink flying phenomenon. Background Technique

[0002] The existing patent (publication number: CN217455349U) discloses "a carton printing machine with the function of preventing ink flying phenomenon, including a heating box, a machine body is installed at the upper end of the heating box, a leak-proof groove is installed in the middle of the front end of the machine body, a leak-proof net is arranged at the upper end of the leak-proof groove, a drain pipe is connected to the left side wall of the leak-proof groove, baffles are arranged on both sides of the upper end of the leak-proof groove, fixing plates are arranged on the baffles, a connecting groove is installed at the front end of the heating box, bases are installed on both sides of the lower end of the connecting groove, a feeding groove is installed at the rear end of the machine body, and an inclined groove is installed at the rear end of the feeding groove; when the cardboard enters the leak-proof groove from the front end, the fixing plate can remove the residual liquid on the cardboard, enter the leak-proof groove through the leak-proof net, open the first solenoid valve regularly, and discharge it to the outside through the drain pipe to avoid causing pollution outside the device, which brings convenience; by starting the heating machine, hot air enters the connecting groove through two air outlet nets to dry the cardboard, saving drying time and having strong practicability."

[0003] The inventor found the following problems in the prior art during the implementation of this application: Each roller inside the device cannot be taken out well. After long-term printing work, if the rollers are not cleaned in time, it is easy to affect subsequent use. When too much stain accumulates, the ink flying phenomenon will occur. At the same time, the device uses a drying method to save drying time. Under the influence of the surrounding environment, the inside will be too dry, and a large amount of static electricity will be generated during the operation between the rollers, which is also a hidden danger leading to ink flying. When cleaning the residual ink on the paper, the device uses a fixing plate. However, when the fixing plate scrapes the ink for a long time, the scraped ink may remain around the fixing plate and cannot be discharged. In subsequent work, it not only cannot continue to scrape the ink, but also scrapes the residual ink on other clean cardboard.

[0004] Therefore, those skilled in the art provide a printing machine with the function of preventing ink flying phenomenon to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages existing in the prior art, and a printing machine with the function of preventing ink flying phenomenon is proposed. Each printing roller inside the device can be conveniently replaced and cleaned, the disassembly process is simpler and more stable, the scraping of residual ink on the paper is more effective, the cleanliness of the internal printing working environment is improved, and the temperature and humidity of the printing environment can be monitored and adjusted in real time to avoid being too dry and generating too much static electricity, and avoid the generation of ink flying phenomenon due to poor environment and static electricity problems inside.

[0006] To achieve the above object, the utility model provides the following technical solutions: A printing press with the prevention of ink splashing phenomenon, including a base, a paperboard and a motor.

At this time, the clamping rods cannot rotate anymore to form a fixation. If it needs to be removed, just push the sliding blocks located in the sliding grooves upward and downward on the outside. After the plurality of clamping rods are inserted, corresponding printing rollers are sleeved on their peripheries. When the inner square columns are inserted into the rotating columns driven by the motors to rotate, the rotation of the printing rollers can be realized. After taking out the clamping rods and opening the top cover, the printing rollers can be taken out for cleaning. The humidifier arranged inside cooperates with the real-time monitoring of the temperature and humidity sensor to adjust the internal humidity and effectively reduce the generation of static electricity.

[0009] Further, a plurality of front driving rollers are rotatably arranged between two plates at the front of the upper end of the base. Two dryers are penetrated through the front of the printing main body close to the front driving rollers;

[0010] Through the above technical solutions, the processed paper can fall on the front driving rollers and be dried by the dryers, reducing the drying time.

[0012] Through the above technical solution, the internal temperature and humidity information of the printing main body can be better controlled, and it can be adjusted according to the environmental temperature and humidity, so that the printing work can be carried out in the optimal environment and ink flying can be avoided.

[0013] Further, a waste liquid filter screen is arranged at the front end opening of the printing main body. Scraping openings are arranged on both sides of the upper end of the waste liquid filter screen. Air suction devices are arranged on the inner side of the printing main body close to the outer sides of the scraping openings. Small filter plates are arranged on the inner wall close to the lower ends between the two air suction devices and the scraping openings. Liquid outlet pipes penetrate through the inner part of the printing main body close to the lower ends of the two scraping openings.

[0014] Through the above technical solution, it is prevented that the residual ink scraped by the scraping openings cannot be discharged in time and pollutes the subsequent clean cardboard. The air suction devices can provide a certain intensity of air flow to guide the residual ink, so that it falls off from the scraping openings and enters the liquid outlet pipes.

[0015] Further, a plurality of card slots are arranged horizontally, a plurality of sliding slots are arranged vertically, and the sizes of the plurality of card slots are the same as the overall sizes of the clamping blocks.

[0016] Through the above technical solution, the clamping rod can be stably and conveniently inserted by means of clamping, and it is convenient to take out subsequently.

[0017] Further, a liquid storage tank is fixedly arranged at the lower front part of one side of the printing main body. A liquid outlet is arranged in the middle of one side of the liquid storage tank.

[0018] Through the above technical solution, the remaining ink and residual ink cannot be recycled immediately. They need to be reprocessed in an additional environment before they can be reused. Otherwise, it will affect the ink quality, and in severe cases, ink flying will be caused.

[0019] The utility model has the following beneficial effects:

[0020] 1. A printing machine with the prevention of ink flying phenomenon proposed by the utility model can conveniently disassemble the printing roller without removing too many bolts. When cleaning is required, only need to first push the sliding block and then rotate the clamping rod to take it out. The clamping is stable and the taking out is convenient, saving the cleaning time. In daily printing work, it can more effectively ensure the cleanliness of the printing roller, prevent the generation of ink flying phenomenon caused by excessive residual ink stains on the printing roller. At the same time, when scraping the residual ink from the cardboard, by setting the air suction device, the scraped ink can be timely guided to the liquid outlet pipe through the air flow, avoiding the accumulation of the scraped ink at the scraping opening and affecting the subsequent clean cardboard.

[0033] Referring to Figure 1-8 , an embodiment provided by the present invention: A printing press with a function of preventing ink splashing, including a base 2, a paper board 31 and a motor 30. A printing main body 1 is fixedly arranged at the upper end of the base 2. A top cover 10 is rotatably arranged at one side near the upper end of the printing main body 1. After removing the clamping rod 9 and then lifting the top cover 10, the printing roller 11 to be cleaned can be taken out. A plurality of clamping rods 9 are penetratingly arranged inside one side of the printing main body 1. A limiting block 27 is fixedly arranged on the surface of the periphery of the plurality of clamping rods 9 close to one side of the printing main body 1. Sliding grooves 25 are respectively arranged at the upper and lower parts near the outer ends of the clamping rods 9 on one side of the printing main body 1;

[0034] Sliding blocks 26 are respectively clamped and slidably arranged inside the plurality of sliding grooves 25. By moving a part of the sliding blocks 26 located in the sliding grooves 25, the movement of the internal part can be controlled, and the clamping rod 9 can be taken away better. Springs 22 are arranged between the parts of the plurality of sliding blocks 26 located inside the printing main body 1 and the printing main body 1. The elasticity of the springs 22 is relatively high. After the clamping rod 9 is inserted, due to the reset action of the springs 22, the clamping rod 9 cannot rotate;

[0035] Clamping blocks 23 are fixedly arranged on the peripheries of the plurality of clamping rods 9 at the positions of the sliding blocks 26. Inner square columns 28 are respectively clamped and rotatably arranged on the other sides of the plurality of clamping rods 9.

A temperature and humidity sensor 16 is fixedly arranged on the inner wall of the printing main body 1 in the direction close to the dryer 4. An inlet main body 19 is arranged on one side of the printing main body 1 away from the front driving rollers 3. A control panel 21 is arranged on one side of the inlet main body 19 away from the front driving rollers 3 and close to the water tank 13. An inlet port 20 is opened in the middle of one side of the inlet main body 19 away from the front driving rollers 3, so as to better control the internal temperature and humidity information of the printing main body 1, and it can be adjusted according to the environmental temperature and humidity, so that the printing work can be carried out in the optimal environment and avoid ink splashing;

[0041] The temperature and humidity sensor 16 is electrically connected to the control panel 21, and the humidifier 17 and the dryer 4 are electrically connected to the control panel 21, so that the control of the internal temperature and humidity can be better controlled and adjusted at any time according to environmental changes. At the opening on one side of the printing main body 1 close to the temperature and humidity sensor 16, a waste liquid filter screen 5 is provided. Scraping openings 33 are provided on both sides at the upper end of the waste liquid filter screen 5. Air suction devices 32 are provided on the inner side of the printing main body 1 close to the outside of the scraping openings 33. Small filter plates are provided on the inner wall near the lower ends between the two air suction devices 32 and the scraping openings 33. Liquid discharge pipes 8 are provided through the lower ends of the printing main body 1 close to the two scraping openings 33, preventing the residual ink scraped by the scraping openings 33 from not being discharged in time and contaminating the subsequent clean cardboard 31. The air suction device 32 can provide a certain intensity of air flow to guide the residual ink, causing it to fall off from the scraping openings 33 and enter the liquid discharge pipes 8;

[0042] A plurality of card slots 24 are arranged horizontally, and a plurality of sliding slots 25 are arranged vertically. The sizes of the plurality of card slots 24 are the same as the overall sizes of the clamping blocks 23, enabling the clamping rod 9 to be stably and conveniently inserted by means of clamping and facilitating subsequent removal. At the lower part of one side of the printing main body 1 close to the front driving roller 3, a liquid storage tank 7 is fixedly provided. An outlet 6 is provided at the middle part of one side of the liquid storage tank 7. The liquid discharge pipes 8 are connected to the liquid inlet of the liquid storage tank 7. The remaining ink and residual ink cannot be recycled immediately and need to be reprocessed in an additional environment before they can be reused, otherwise it will affect the quality of the ink, and in severe cases, ink spattering will occur.

[0043] Working principle: After the device is used once, before the next use, the internal printing roller 11 needs to be cleaned. At this time, the sliding blocks 26 located in the sliding slots 25 are respectively pushed up and down to release the clamping of the clamping blocks 23 on the clamping rod 9, and the clamping rod 9 can be taken out by rotating it. At this time, the top cover 10 is lifted to take out the printing roller 11 for cleaning work. During the operation of the printing roller 11, the internal temperature and humidity are monitored in real time by the temperature and humidity sensor 16 and controlled through the control panel 21. When the inside is too dry, the water pump 14 and the humidifier 17 are controlled to be turned on to increase the internal humidity. When the cardboard 31 passes through the waste liquid filter screen (5), the residual ink can be scraped off through the scraping openings 33. Affected by the air suction device 32, the ink is guided by the internal air flow and can immediately enter the liquid storage tank 7 through the liquid discharge pipes 8 after being scraped off, facilitating subsequent reprocessing and reuse.

[0044] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
