Description

Technical Field

[0001] The present invention relates to the technical field of printing presses, and more specifically, to an environment-friendly packaging and decoration printing press. Background Art

[0002] Packaging and decoration refers to the shape and surface design of packaging. On the basis of being scientific and reasonable, it is decorated and beautified so that various elements such as the shape, pattern, color, text, and trademark brand of the packaging form an artistic whole, playing roles such as transmitting product information, showing product characteristics, promoting products, beautifying products, facilitating sales, and facilitating consumption.

[0003] During the use of existing printing presses for packaging and decoration, before entering the printing process, some dust or other tiny impurities may adhere to their surfaces, which will cause the printed patterns to be blurred and unclear, seriously affecting the quality of printed products.

[0004] In response to the above problems, some solutions have also been given in the prior art. For example, the Chinese invention patent with the publication number CN113879876B discloses a feeding device for a packaging and decoration printing press. This device uses a dust suction pump to make the dust suction head adsorb the surface of the material, suck away the dust and impurities remaining on the surface, and enter the dust collection box through the dust suction pipe for centralized collection, so that after cleaning the dust on the printing surface, it will not affect the appearance effect during printing and make the printing effect better; although the prior art can clean the surface of the material before printing, it does not dry the printed product after printing. Then, the surface of the printed product may not be fully dried. When the printed surface of the printed product touches other printed products, the patterns on the surface of the printed product may become blurred or fall off, thus seriously affecting the quality of the printed product, and the patterns on the surface of the printed product are prone to emitting waste gas during the drying process, polluting the air and seriously affecting the health of workers.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 to 8 , an environment-friendly packaging and decoration printing press, including a workbench 1, a printing press body 2 is installed on the top wall of the workbench 1, a discharge roller 3 is provided on the workbench 1, and a drying assembly 4 is provided on the workbench 1; The drying component 4 includes a drying hood 401 installed on the top wall of the workbench 1. A first mounting rod 402 is rotatably installed on the side wall of the drying hood 401. A material receiving roller 403 is detachably installed on the first mounting rod 402. A drying plate 404 is fixedly installed on the side wall of the drying hood 401. A drying cavity 405 is formed in the drying plate 404. Drying holes 406 are formed in the bottom wall of the drying cavity 405. Heating rods 407 are uniformly and fixedly installed on the inner wall of the drying cavity 405. A first air pipe 408 communicating with the outside is inserted into the side wall of the drying cavity 405. An air pump 409 is installed on the bottom wall of the workbench 1. An air inlet pipe 410 is inserted into the input end of the air pump 409. A purification component 5 is provided on the workbench 1. The air inlet pipe 410 is communicated with the first air pipe 408 through the purification component 5.

[0022] The purification component 5 includes a purification box 501 fixedly installed on the bottom wall of the workbench 1. Air purification particles are contained in the purification box 501. A rotating rod 502 extending into the air inlet pipe 410 is rotatably installed in the purification box 501. Mixing rods 503 are uniformly and fixedly installed on the rotating rod 502. An impeller 504 is fixedly installed at one end of the rotating rod 502 located in the air inlet pipe 410. A second air pipe 505 communicating with the drying hood 401 is inserted into the purification box 501. A blocking component 6 for blocking the second air pipe 505 is provided on the purification box 501.

[0023] The blocking component 6 includes a vertical groove formed in the purification box 501. A sealing plate 601 is slidably installed in the vertical groove. A magnet block 602 is fixedly installed on the sealing plate 601. An electromagnet 603 electrically connected to the air pump 409 is embedded in the purification box 501.

[0024] During use, the printing material wound on the discharging roller 3 is wound onto the material receiving roller 403 through the printing machine body 2. During the process that the printing material passes through the printing machine body 2, the printing machine body 2 can print the printing material. At the same time, the air pump 409 is started. Then the air pump 409 inhales air from the drying hood 401 through the purification component 5 at the input end, so that the outside air flow flows into the drying cavity 405 through the first air pipe 408. Then the heating rods 407 can heat the air flow flowing through the drying cavity 405. The heated air flow blows onto the printed printing material through the drying holes 406 on the drying cavity 405, so that the printed matter can be dried, effectively preventing the pattern on the surface of the printed matter from being rubbed and blurred, and playing a role in improving the printing quality.

[0025] The patterns on the printed matter will generate waste gas during the drying process. If the waste gas cannot be treated in time, it is easy to pollute the air and affect the health of the staff. During the process of the air pump 409 sucking air from the drying hood 401 through the intake pipe 410 and the purification component 5, the air flow flows through the second air pipe 505 to the purification box 501, and then through the purification box 501 to the intake pipe 410. And during the process of the air flow passing through the purification box 501, the air purification particles in the purification box 501 can absorb the waste gas in the air flow. And during the process of the air flow passing through the intake pipe 410, it will drive the impeller 504 to rotate. Then during the rotation of the impeller 504, it can drive the rotating rod 502 to rotate. And during the rotation of the rotating rod 502, it can stir the air purification particles in the purification box 501, so as to avoid the air purification particles in contact with the air flow first being saturated prematurely and affecting the absorption effect of the waste gas, playing a role in reducing pollution.

[0026] When the air pump 409 works, the electromagnet 603 is energized and generates a magnetic field. Then under the action of the electromagnetic field, the magnet block 602 drives the sealing plate 601 to move upward. At this time, the purification box 501 is communicated with the second air pipe 505. Then when the printing is over, the air pump 409 is powered off, and then the electromagnet 603 is powered off and the electromagnetic field disappears. At this time, the sealing plate 601 slides downward along the vertical groove under the action of gravity and separates the purification box 501 from the second air pipe 505, so as to avoid moisture or impurities in the external air flow entering the purification box 501 during the long-term stop of printing, resulting in the rapid saturation of the air purification particles and affecting the adsorption effect of the air purification particles, further reducing air pollution.

[0027] Such as Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 As shown in

[0028] A cleaning hood 701 is fixedly installed on the top wall of the workbench 1. And symmetrically rotatably installed in the cleaning hood 701 are second mounting rods 702. And the discharging roller 3 is detachably installed on the second mounting rods 702. A motor 703 with an output end fixedly connected to the second mounting rods 702 is fixedly installed on the cleaning hood 701. And a first belt 704 is jointly installed between the second mounting rods 702 and the first mounting rods 402.

[0029] A cleaning rod 901 is rotatably installed on the cleaning cover 701. A second belt 902 is installed on both the cleaning rod 901 and the second mounting rod 702. And brush hairs 903 are uniformly and fixedly installed on the cleaning rod 901.

[0030] By adopting the above technical solution, during use, first install the discharging roller 3 on the second mounting rod 702, and install the material collecting roller 403 on the first mounting rod 402. During operation, first start the motor 703, and then the motor 703 drives the discharging roller 3 to rotate through the second mounting rod 702. At the same time, during the rotation of the second mounting rod 702, the first mounting rod 402 is driven to rotate through the first belt 704. Then, during the rotation of the first mounting rod 402, the material collecting roller 403 is driven to rotate. And during the rotation of the discharging roller 3 and the material collecting roller 403, the printing raw material is gradually driven through the printing machine body 2 and wound on the material collecting roller 403, achieving the purpose of printing the printing raw material.

[0031] When the drying chamber 405 sucks air from the outside through the first air pipe 408, the first air pipe 408 sucks air from the collection tank 803 through the collection box 801 and the third air pipe 805. And the collection tank 803 sucks air through the collection holes 804. Then the airflow drives the impurities on the printing raw material to flow into the collection box 801, thus preventing the impurities on the surface of the printing raw material from affecting the printing effect and further improving the printing effect.

[0032] And during the rotation of the second mounting rod 702, the cleaning rod 901 is driven to rotate through the second belt 902. Then the cleaning rod 901 drives the brush hairs 903 to rotate. And during the rotation of the brush hairs 903, the impurities on the printing raw material can be cleaned, so that the impurities firmly adhered to the printing raw material are separated from the printing raw material. Then the impurities separated from the printing raw material flow into the collection box 801 together with the airflow, further improving the printing effect.

[0033] Such as Figure 1 、 Figure 5 As shown, combing rods 101 are uniformly and vertically fixedly installed on the bottom wall of the collection plate 802.

[0034] An exhaust pipe 102 is communicated with the output end of the air pump 409. And the exhaust pipe 102 is rotationally matched with the cleaning rod 901. Exhaust holes 104 are formed in the exhaust pipe 102, and communication holes 105 matched with the exhaust holes 104 are uniformly formed in the cleaning rod 901.

[0035] By adopting the above technical solution, during the process of the cleaning rod 901 driving the bristles 903 to rotate, it gradually contacts the combing rod 101. Then, the combing rod 101 will strike the bristles 903, so that the stains adhering to the bristles 903 are separated from the bristles 903 and enter the collection box 801 along with the air flow. Thus, it effectively avoids impurities adhering to the bristles 903 and reattaching to the surface of the printing material, which affects the printing quality. And during the process of the bristles 903 passing through the combing rod 101, the combing rod 101 can also comb the bristles 903, thereby improving the cleaning effect of the bristles 903 and further improving the printing quality.

[0036] When the air pump 409 is working, the gas entering the air pump 409 through the air inlet pipe 410 flows towards the exhaust pipe 102, then flows through the exhaust holes 104 on the exhaust pipe 102 towards the communication holes 105, and blows towards the contact area between the bristles 903 and the printing material through the communication holes 105. Thus, impurities and dust can be suspended in the air, and the impurities are driven by the air flow into the collection box 801, further improving the cleaning effect.

[0037] As Figure 2 、 Figure 4 As shown in the figure, the first limiting rods 11 are symmetrically and rotatably installed on the cleaning cover 701, and the second limiting rods 12 are rotatably installed on the drying cover 401.

[0038] By adopting the above technical solution, when the printing material moves into the printing machine body 2 through the cleaning cover 701, the printing material contacts the first limiting rods 11 and drives the first limiting rods 11 to rotate. Then, the first limiting rods 11 can limit the printing material to avoid the printing material from shifting and affecting the printing effect. At the same time, it can also separate the cleaning cover 701 from the printing material, avoiding the drying cover 401 from sucking air from the cleaning cover 701 through the printing machine body 2 when the second air pipe 505 sucks air from the drying cover 401, further improving the printing quality.

[0039] As Figure 3 、 Figure 7 As shown in the figure, a filter screen 13 for filtering impurities is provided in the collection box 801, and a feeding port and a discharging port are respectively opened on the purification box 501, and a first plug board 14 and a second plug board 15 are respectively detachably installed in the feeding port and the discharging port.

[0040] By adopting the above technical solution, by setting the filter screen 13, the impurities entering the collection box 801 can be filtered to avoid the impurities from entering the drying cover 401 and affecting the printing effect. And when it is necessary to replace the air purification particles, the user can first open the second plug board 15 and take out the saturated air purification particles from the discharging port, then close the second plug board 15, and open the first plug board 14 to put new air purification particles into the purification box 501 through the feeding port.

[0041] Usage method: When in use, the printing material wound on the discharging roller 3 is wound onto the receiving roller 403 through the printing press body 2. And during the process that the printing material passes through the printing press body 2, the printing press body 2 can print on the printing material. At the same time, start the air pump 409, and then the air pump 409 sucks air from the drying hood 401 through the input end purification component 5, so that the outside air flows through the first air pipe 408 into the drying cavity 405. Then the heating rod 407 can heat the air flowing through the drying cavity 405, and the heated air blows onto the printed printing material through the drying holes 406 on the drying cavity 405, so as to dry the printed matter; the pattern on the printed matter will generate waste gas during the drying process. If the waste gas cannot be processed in time, it is easy to pollute the air and affect the health of the staff. During the process that the air pump 409 sucks air from the drying hood 401 through the air inlet pipe 410 and the purification component 5, the air flow flows through the second air pipe 505 into the purification box 501 and flows through the purification box 501 into the air inlet pipe 410. And during the process that the air flow passes through the purification box 501, the air purification particles in the purification box 501 can absorb the waste gas in the air flow. And during the process that the air flow passes through the air inlet pipe 410, it will drive the impeller 504 to rotate. Then during the rotation of the impeller 504, it can drive the rotating rod 502 to rotate. And during the rotation of the rotating rod 502, it can stir the air purification particles in the purification box 501, so as to prevent the air purification particles that first come into contact with the air flow from being saturated prematurely and affecting the absorption effect of the waste gas; after the electromagnet 603 is powered off, the electromagnetic field disappears. At this time, the sealing plate 601 slides down along the vertical groove under the action of gravity and separates the purification box 501 from the second air pipe 505, so as to prevent the moisture or impurities in the outside air flow from entering the purification box 501 and causing the air purification particles to be saturated quickly when the printing stops for a long time; when the drying cavity 405 sucks air from the outside through the first air pipe 408, the first air pipe 408 sucks air from the collection tank 803 through the collection box 801 and the third air pipe 805, and the collection tank 803 sucks air through the collection holes 804. Then the air flow drives the impurities on the printing material to flow into the collection box 801 together; and during the rotation of the second mounting rod 702, the cleaning rod 901 is driven through the second belt 902. Then the cleaning rod 901 drives the brush bristles 903 to rotate. And during the rotation of the brush bristles 903, it can clean the impurities on the printing material, so that the impurities firmly adhered to the printing material are separated from the printing material;During the process of the cleaning rod 901 driving the bristles 903 to rotate, the bristles gradually come into contact with the combing rod 101. Then, the combing rod 101 will strike the bristles 903, so that the stains adhering to the bristles 903 are separated from the bristles 903 and enter the collection box 801 along with the airflow. This effectively prevents impurities from adhering to the bristles 903 and reattaching to the surface of the printing material, which may affect the printing quality. Moreover, during the process of the bristles 903 passing through the combing rod 101, the combing rod 101 can also comb the bristles 903, thereby improving the cleaning effect of the bristles 903.

[0042] The above is only the preferred specific implementation mode of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
