Description

Technical Field

[0001] The invention relates to the technical field of printing rollers, in particular to a printing roller for preventing printing glue from solidifying. Background Art

[0002] The printing roller is a key component in printing machinery used for embossing, ink mixing and ink transfer. With its unique structure and material, the printing roller can effectively adjust the flow and distribution of ink to ensure that the color of the printed product is full and uniform.

[0003] When the existing printing roller is working, it is necessary to heat the printing roller in advance. After working for a long time, the temperature of the printing roller gradually decreases, causing the printing glue to solidify on the surface of the printing roller. This solidification not only leads to a decrease in printing quality, but also causes downtime for maintenance, seriously affecting production efficiency.

[0004] To this end, the present invention provides a printing roller for preventing the printing glue from solidifying. Summary of the invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The present invention provides a printing roller for preventing printing glue from solidifying, comprising a printing machine support, and further comprising: a printing mechanism arranged on the inner wall of the printing machine support, the printing mechanism being used for printing printing materials; a scraping mechanism arranged on the inner wall of the printing machine support, the scraping mechanism being used for scraping off excess printing glue in the printing mechanism to keep the surface of the printing mechanism clean and tidy; a spray mechanism arranged on the inner wall of the printing machine support, the spray mechanism being used for spraying an anti-coagulant on the surface of the printing mechanism to prevent the printing glue from solidifying at high temperatures; a transmission mechanism arranged on the outer side of the printing machine support, the transmission mechanism being used for making the scraping mechanism and the spray mechanism work synchronously; a collecting mechanism arranged inside the printing machine support, the collecting mechanism being used for collecting the printing glue scraped off by the scraping mechanism; and a control panel arranged on the outer side of the printing machine support, the control panel being used for adjusting the working frequencies of the spray mechanism and the scraping mechanism.

[0007] By adopting the above technical solution, the scraping mechanism can efficiently scrape off the excess printing glue on the surface of the printing mechanism to ensure the cleanliness of the printing surface. At the same time, the spray mechanism also starts to work to evenly spray the anti-coagulant on the surface of the printing mechanism. The function of the anti-coagulant is to lower the solidification point of the printing glue to prevent it from solidifying due to temperature drop during the printing process, thereby ensuring the continuity and stability of printing.

[0008] Preferably, the printing mechanism includes a rotating shaft rotatably connected to the inner wall of the printing machine bracket, a printing roller is fixedly connected to the outer side of the rotating shaft, one end of the rotating shaft passes through and is rotatably connected to the printing machine bracket, one end of the rotating shaft passing through the printing machine bracket is fixedly connected to a first motor, the lower end of the first motor is fixedly connected to a first support plate, and one side of the first support plate is fixedly connected to the outer side of the printing machine bracket.

[0009] By adopting the above technical solution, the printing roller rotates. As the printing roller rotates, its surface contacts the material to be printed, thereby accurately transferring the printed pattern or text to the material to be printed, completing the printing process.

[0010] Preferably, the scraping mechanism includes a first reciprocating screw rod rotatably connected to the inner wall of the printing press bracket, the inner wall of the printing press bracket is fixedly connected to a first limiting tube, the outer side of the first reciprocating screw rod is threadedly connected to a first sliding block, the outer side of the first limiting tube is slidably connected to a first sliding block, and the first sliding block is fixedly connected to two first mounting plates on one side close to the printing roller.

[0011] By adopting the above technical solution, the first reciprocating screw is rotated to drive the first sliding block to slide along the axial direction of the first reciprocating screw, so that the first sliding block can be accurately moved to a predetermined position.

[0012] Preferably, the inner wall of the first mounting plate is rotatably connected to a first rotating tube, one end of the first rotating tube passes through and is rotatably connected to the first mounting plate, one side of the first rotating tube passing through the first mounting plate is fixedly connected to a second motor, and the outer side of the first rotating tube is fixedly connected to a scraper.

[0013] By adopting the above technical solution, the second motor is started, and the second motor is connected to the first rotating tube through its output shaft. When the second motor rotates, it drives the first rotating tube to rotate around its axis. Since the scraper is fixed on the first rotating tube, the inclination angle of the scraper changes with the rotation of the first rotating tube.

[0014] Preferably, the spray mechanism includes a second reciprocating screw rotatably connected to the inner wall of the printing press bracket, the inner wall of the printing press bracket is fixedly connected to a second limiting tube, the outer side of the second reciprocating screw is threadedly connected to a second sliding block, the outer side of the second limiting tube is slidably connected to a second sliding block, the second sliding block is fixedly connected to two second mounting plates on one side close to the printing roller, and the inner side of the second mounting plate is fixedly connected to a spray box.

[0015] Preferably, a spray head is fixedly connected to the side of the spray box close to the printing roller, an elastic tube is fixedly connected to the bottom end of the spray box, the other end of the elastic tube passes through and is slidably connected to the printing machine bracket, one end of the elastic tube passing through the printing machine bracket is fixedly connected to a liquid pump, and the side of the liquid pump away from the elastic tube is fixedly connected to a liquid outlet pipe of a liquid storage tank.

[0016] By adopting the above technical solution, the printing glue on the outer side of the printing roller is effectively prevented from solidifying at high temperature, thereby ensuring the smooth progress of the printing process and the stability of the printing quality.

[0017] Preferably, the transmission mechanism includes a mounting tube 1 and a mounting tube 2 which penetrate through and are rotatably connected to the printing press bracket, wherein one end of the mounting tube 1 penetrates through the printing press bracket and is fixedly connected to the first reciprocating screw rod, and one end of the mounting tube 2 penetrates through the printing press bracket and is fixedly connected to the second reciprocating screw rod.

[0018] Preferably, the ends of the mounting tube 1 and the mounting tube 2 away from the printing press bracket are respectively fixedly connected with the first pulley and the second pulley, the outer sides of the first pulley and the second pulley are connected with belts for transmission, and the end of the first pulley away from the mounting tube 1 is fixedly connected with the third motor.

[0019] By adopting the above technical solution, the transmission mechanism ensures accurate transmission of power and avoids errors or failures caused by poor transmission. As the second pulley rotates, the first reciprocating screw and the second reciprocating screw connected to it also start to rotate. The two reciprocating screws are responsible for the motion control of the scraping mechanism and the spraying mechanism respectively. Their synchronous rotation ensures that the scraping and spraying actions can be carried out simultaneously, improving work efficiency and coordination of operation.

[0020] Preferably, the collecting mechanism comprises a collecting box fixedly connected to the lower end of the first sliding block, and the inner wall of the printing press bracket is fixedly connected with a storage box.

[0022] By adopting the above technical solution, the dust accumulated inside the collection box and impurities such as solidified printing rubber blocks can be smoothly dropped into the storage box below under the action of gravity, thereby achieving effective cleaning and collection of the impurities.

[0023] The beneficial effects of the present invention are as follows: the printing roller for preventing the printing glue from solidifying described in the present invention ensures that the printing machine is in a safe and ready state, then turns on the power switch of the printing machine, starts the preheating program of the printing mechanism, and gradually heats it to a preset working temperature. Then, the transmission mechanism is started, so that the transmission mechanism drives the scraping mechanism and the spray mechanism to work synchronously. The scraping mechanism can efficiently scrape off the excess printing glue on the surface of the printing mechanism to ensure the cleanliness of the printing surface. At the same time, the spray mechanism also starts to work to evenly spray the anti-coagulant on the surface of the printing mechanism. The function of the anti-coagulant is to lower the solidification point of the printing glue to prevent it from solidifying due to temperature drop during the printing process, thereby ensuring the continuity and stability of the printing.

[0024] The printing roller for preventing the printing glue from solidifying described in the present invention, when the solidified printing glue on the upper end of the scraper is shaken off, these solidified printing glue blocks will accurately fall into a specially designed collection box. Subsequently, the first sliding block drives the collection box to move together in the process of moving along a preset trajectory. When the collection box moves to a specific position, that is, when it comes into contact with the poking tube, the poking tube will trigger the collection box, causing the block inside the collection box to rotate. This rotation action further causes the dust accumulated inside the collection box and impurities such as solidified printing glue blocks to fall smoothly into the storage box below under the action of gravity, thereby achieving effective cleaning and collection of impurities.

[0027] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification.

[0028] The following is a further detailed description of the technical solution of the present invention in conjunction with the accompanying drawings and specific embodiments. Figures 1 to 7 , the present application provides a printing roller for preventing the printing glue from solidifying, please refer to Figure 1 , Figure 2 , including a printing machine support 1, and also including: a printing mechanism 2 arranged on the inner wall of the printing machine support 1, the printing mechanism 2 is used to print printing materials; a scraping mechanism 3 arranged on the inner wall of the printing machine support 1, the scraping mechanism 3 is used to scrape off excess printing glue in the printing mechanism 2 to keep the surface of the printing mechanism 2 clean; a spray mechanism 4 arranged on the inner wall of the printing machine support 1, the spray mechanism 4 is used to spray an anti-coagulant on the surface of the printing mechanism 2 to prevent the printing glue from solidifying at high temperature; a transmission mechanism 5 arranged on the outside of the printing machine support 1, the transmission mechanism 5 is used to synchronize the scraping mechanism 3 and the spray mechanism 4; a collecting mechanism 7 arranged inside the printing machine support 1, the collecting mechanism 7 is used to collect the printing glue scraped off by the scraping mechanism 3; a control panel 6 arranged on the outside of the printing machine support 1, the control panel 6 is used to adjust the working frequency of the spray mechanism 4 and the scraping mechanism 3.

[0029] Specifically, in the initial state, first ensure that the printing press is in a safe and ready state, then turn on the power switch of the printing press, start the preheating program of the printing mechanism 2, and gradually heat it to the preset working temperature. Then, start the transmission mechanism 5, so that the transmission mechanism 5 drives the scraping mechanism 3 and the spray mechanism 4 to work synchronously. The scraping mechanism 3 can efficiently scrape off the excess printing glue on the surface of the printing mechanism 2 to ensure the cleanliness of the printing surface. At the same time, the spray mechanism 4 also starts to work and evenly sprays the anti-coagulant on the surface of the printing mechanism 2. The function of the anti-coagulant is to lower the solidification point of the printing glue and prevent it from solidifying due to temperature drop during the printing process, thereby ensuring the continuity and stability of the printing. In addition, the printing press is also equipped with a collecting mechanism 7, which is used to collect the printing glue scraped off by the scraping mechanism 3.

[0030] Please refer to Figure 3 The printing mechanism 2 includes a rotating shaft 21 rotatably connected to the inner wall of the printing machine bracket 1, a printing roller 22 is fixedly connected to the outer side of the rotating shaft 21, one end of the rotating shaft 21 passes through and is rotatably connected to the printing machine bracket 1, one end of the rotating shaft 21 passing through the printing machine bracket 1 is fixedly connected to a first motor 23, the lower end of the first motor 23 is fixedly connected to a first support plate 24, and one side of the first support plate 24 is fixedly connected to the outer side of the printing machine bracket 1.

[0031] Specifically, by starting the first motor 23, the first motor 23 will output power to drive the rotating shaft 21 to start rotating. The rotating shaft 21 serves as a transmission component to transmit its rotational motion to the printing roller 22 connected to its outer side, so that the printing roller 22 also rotates. As the printing roller 22 rotates, its surface contacts the material to be printed, thereby accurately transferring the printed pattern or text to the material to be printed, completing the printing process.

[0032] Please refer to Figure 4 The scraping mechanism 3 includes a first reciprocating screw rod 31 rotatably connected to the inner wall of the printing machine bracket 1, a first limiting tube 32 is fixedly connected to the inner wall of the printing machine bracket 1, a first sliding block 33 is threadedly connected to the outer side of the first reciprocating screw rod 31, a first sliding block 33 is slidably connected to the outer side of the first limiting tube 32, two first mounting plates 34 are fixedly connected to the side of the first sliding block 33 close to the printing roller 22, a first rotating tube 35 is rotatably connected to the inner wall of the first mounting plate 34, one end of the first rotating tube 35 passes through and is rotatably connected to the first mounting plate 34, a second motor 36 is fixedly connected to the side of the first rotating tube 35 that passes through the first mounting plate 34, and a scraper 37 is fixedly connected to the outer side of the first rotating tube 35.

[0033] Specifically, through the rotation of the first reciprocating screw 31, the thread on its surface cooperates with the thread inside the first sliding block 33, thereby driving the first sliding block 33 to slide along the axial direction of the first reciprocating screw 31, so that the first sliding block 33 can accurately move to the predetermined position, and the groove on the outer side of the first limiting tube 32 drives the scraper 37 to shake slightly, so that the solidified printing glue falling on the upper end of the scraper 37 is shaken off. During the sliding process, the scraper 37 carried by the first sliding block 33 contacts the surface of the printing roller 22, and the excess printing glue on the surface of the printing roller 22 is effectively scraped off. The cleanliness and printing quality of the printing roller 22 are ensured. In order to further adjust the inclination angle of the scraper 37 to adapt to different printing requirements and the surface conditions of the printing roller 22, the second motor 36 is started. The lower end of the second motor 36 is fixedly connected to the second support plate. The second motor 36 is connected to the first rotating tube 35 through its output shaft. When the second motor 36 rotates, it drives the first rotating tube 35 to rotate around its axis. Since the scraper 37 is fixed on the first rotating tube 35, the inclination angle of the scraper 37 changes with the rotation of the first rotating tube 35.

[0034] Please refer to Figure 7 The collecting mechanism 7 is arranged at the lower end of the first sliding block 33, and the collecting mechanism 7 includes a collecting box 71 fixedly connected to the lower end of the first sliding block 33. The inner wall of the printing machine bracket 1 is fixedly connected to the storage box 73. The inner wall of the printing machine bracket 1 is fixedly connected to the upper end of the storage box 73 with a poking tube 74. The inner wall of the collecting box 71 is rotatably connected to a stopper 72 on one side of the inner wall facing the storage box 73 through a mounting tube.

[0035] Specifically, when the solidified printed glue on the upper end of the scraper 37 is shaken off, these solidified printed glue blocks will accurately fall into the specially designed collection box 71. Subsequently, the first sliding block 33 drives the collection box 71 to move together in the process of moving along the preset trajectory. When the collection box 71 moves to a specific position, that is, when it comes into contact with the poking tube 74, the poking tube 74 will trigger the collection box 71, causing the block 72 inside the collection box 71 to rotate. This rotation action further causes the dust accumulated inside the collection box 71 and impurities such as solidified printed glue blocks to fall smoothly into the storage box 73 below under the action of gravity, thereby achieving effective cleaning and collection of impurities.

[0036] Please refer to Figure 5The spray mechanism 4 includes a second reciprocating screw rod 41 rotatably connected to the inner wall of the printing machine bracket 1, a second limiting tube 42 is fixedly connected to the inner wall of the printing machine bracket 1, a second sliding block 43 is threadedly connected to the outer side of the second reciprocating screw rod 41, and a second sliding block 43 is slidably connected to the outer side of the second limiting tube 42. Two second mounting plates 44 are fixedly connected to the side of the second sliding block 43 close to the printing roller 22, a spray box 45 is fixedly connected to the inner side of the second mounting plate 44, a spray head 46 is fixedly connected to the side of the spray box 45 close to the printing roller 22, an elastic tube 47 is fixedly connected to the bottom end of the spray box 45, and the other end of the elastic tube 47 passes through and is slidably connected to the printing machine bracket 1, one end of the elastic tube 47 passing through the printing machine bracket 1 is fixedly connected to a liquid pump 48, and the side of the liquid pump 48 away from the elastic tube 47 is fixedly connected to the liquid outlet pipe of the liquid storage tank 49.

[0037] Specifically, the anticoagulant is safely and effectively transported to the liquid storage tank 49 for storage through the liquid inlet pipe of the liquid storage tank 49. Then, the second reciprocating screw 41 starts to rotate, and the threads on its surface are closely matched with the threads inside the second sliding block 43, thereby driving the second sliding block 43 to slide smoothly along the axial direction of the second reciprocating screw 41. During the sliding process, the second sliding block 43 is closely connected to the spray box 45 through the second mounting plate 44, thereby driving the spray box 45 to slide together, and then starting the liquid pump 48. , the liquid pump 48 starts working, and efficiently transports the anticoagulant in the liquid storage tank 49 to the elastic tube 47 through the liquid outlet pipe. The elastic tube 47 serves as a transmission channel for the anticoagulant. Its flexibility and pressure resistance ensure that the anticoagulant can smoothly reach the spray head 46. Finally, the anticoagulant is evenly sprayed onto the surface of the printing roller 22 through the spray head 46 of the spray box 45. This spraying process effectively prevents the printing glue on the outside of the printing roller 22 from solidifying at high temperature, thereby ensuring the smooth progress of the printing process and the stability of printing quality.

[0038] Please refer to Figure 4 , Figure 5 , Figure 6 The transmission mechanism 5 includes a mounting tube 1 51 and a mounting tube 2 52 which penetrate through and are rotatably connected to the printing machine bracket 1. One end of the mounting tube 1 51 penetrates through the printing machine bracket 1 and is fixedly connected to the first reciprocating screw rod 31. One end of the mounting tube 2 52 penetrates through the printing machine bracket 1 and is fixedly connected to the second reciprocating screw rod 41. The ends of the mounting tube 1 51 and the mounting tube 2 52 away from the printing machine bracket 1 are respectively fixedly connected to the first pulley 53 and the second pulley 54. The outer sides of the first pulley 53 and the second pulley 54 are transmission-connected with a belt 55. The end of the first pulley 53 away from the mounting tube 1 51 is fixedly connected to the third motor 56.

[0039] Specifically, by starting the third motor 56, the third motor 56 outputs power to drive the first pulley 53 connected thereto to start rotating. Under the transmission action of the belt 55, the rotation of the first pulley 53 is effectively transmitted to the second pulley 54, so that the second pulley 54 can keep synchronous rotation with the first pulley 53. This transmission mechanism ensures the accurate transmission of power and avoids errors or failures caused by poor transmission. As the second pulley 54 rotates, the first reciprocating screw 31 and the second reciprocating screw 41 connected thereto also start rotating. These two reciprocating screws are responsible for the motion control of the scraping mechanism 3 and the spray mechanism 4, respectively. Their synchronous rotation ensures that the two actions of scraping and spraying can be performed simultaneously, thereby improving work efficiency and coordination of operation.

[0040] Working principle: in the initial state, first ensure that the printing press is in a safe and ready state, then turn on the power switch of the printing press, start the third motor 56, and the third motor 56 drives the first pulley 53 to start rotating. Under the transmission action of the belt 55, the rotation of the first pulley 53 is transmitted to the second pulley 54, so that the second pulley 54 can rotate synchronously with the first pulley 53. As the second pulley 54 rotates, the first reciprocating screw 31 and the second reciprocating screw 41 connected thereto also start rotating. Thereby, the scraping and spraying actions can be performed simultaneously. The first sliding block 33 is driven to slide along the axial direction of the first reciprocating screw 31 through the rotational movement of the first reciprocating screw 31, so that the first sliding block 33 can be accurately moved to the predetermined position. During the sliding process, the scraper 37 carried by the first sliding block 33 contacts the surface of the printing roller 22, and the excess printing glue on the surface of the printing roller 22 is effectively scraped off. The anticoagulant is transported to the inside of the liquid storage tank 49 through the liquid inlet pipe of the liquid storage tank 49 for storage. Then, the second reciprocating screw 41 starts to rotate, and the thread on its surface is tightly matched with the thread inside the second sliding block 43, thereby driving the second sliding block 43 to move smoothly along the axial direction of the second reciprocating screw 41 During the sliding process, the second sliding block 43 is tightly connected to the spray box 45 through the second mounting plate 44, thereby driving the spray box 45 to slide together, and then starting the liquid pump 48, the liquid pump 48 starts to work, and the anticoagulant in the liquid storage tank 49 is efficiently transported to the elastic tube 47 through the liquid outlet pipe. Finally, the anticoagulant is evenly sprayed onto the surface of the printing roller 22 through the spray head 46 of the spray box 45. By starting the first motor 23, the first motor 23 will output power, drive the rotating shaft 21 to start rotating, so that the printing roller 22 also rotates. As the printing roller 22 rotates, its surface contacts with the material to be printed, thereby accurately transferring the printed pattern or text to the material to be printed, completing the printing process.

[0041] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
