Description
Technical Field
[0001] The utility model relates to the technical field of printing plate cylinders, in particular to a printing device equipped with an automatically lubricated plate cylinder. Background Art
[0002] The plate cylinder, also called a steel roller, is divided into a hollow roller and a solid roller, a roller with a shaft and a roller without a shaft. It is generally used for plate making. The surface of the drum is plated with copper, engraved with patterns by an intaglio electronic engraving machine, and then plated with a layer of chromium. After completion, it is delivered to the printing factory and is commonly used for the printing of plastic packaging. Moreover, the machine equipped with this plate cylinder is called a plate cylinder printing machine. It is difficult to achieve automatic lubrication for the plate cylinder on a traditional printing machine. That is to say, although lubricating oil is brushed on the surface of the plate cylinder before the start of work, during long-term printing work, the lubricating oil on the surface of the plate cylinder will be carried away by the plastic packaging for a long time in contact with the plastic packaging. As a result, in subsequent work, the friction between the plate cylinder and the plastic packaging increases, which easily damages the plastic packaging. Users need to pause the machine every once in a while, clean the packaging bag on the plate cylinder, and then brush lubricating oil on the plate cylinder. However, in this way, the machine stops frequently, reducing the production efficiency of the packaging bag. High-frequency lubrication of the plate cylinder also reduces the work efficiency of users.

[0012] In summary, the beneficial effects of the present utility model are as follows:
[0013] 1. The present utility model adopts a structural design of automatically lubricating the printing plate cylinder, and the lubricating work can be completed during the normal operation of the plate cylinder and in the interval gap between the front and back connections of plastic packaging, without pausing the machine, so that the printing work can be carried out continuously, saving a large amount of time, improving the production efficiency of printed products, and providing convenience for the work and use of users.
[0014] 2. Through the setting of the fixing frame and the plate cylinder body in the present utility model, the plate cylinder body is used for printing and processing the packaging.

Specific embodiments
[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the appended Figures 1-5 , and it is obvious that the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present utility model. Embodiment
[0027] A printing device equipped with an automatically lubricated plate roller includes a base 1. A slide rail 2 is fixedly connected to the bottom inside the base 1. A slide block 3 is slidably installed on the surface of the slide rail 2. An outer hoop 7 is fixedly connected to the top of the slide block 3. A threaded sleeve 4 is fixedly connected to one side of the slide block 3. A rotating screw 5 penetrates through one side of the threaded sleeve 4. One end of the rotating screw 5 is rotatably installed on the inner wall of the base 1. The other end of the rotating screw 5 penetrates to the outside of the base 1. An inner hoop 6 is detachably installed inside the outer hoop 7. A pulley 1 9 is fixedly installed on one side of the surface of the rotating screw 5. Injectors 8 are uniformly distributed through the surface of the outer hoop 7. One end of the injector 8 penetrates to the inside of the inner hoop 6.
[0028] The specific usage process is as follows: The installation position of the inner hoop 6 is outside the surface of the plate roller body 16, and there is a certain gap between the inner wall of the inner hoop 6 and the surface of the plate roller body 16. In this way, the injector 8 can smoothly complete the oil injection work. While the injector 8 is injecting oil, the stepping motor 10 is also started to work. The stepping motor 10 drives the second pulley 11 to rotate. The second pulley 11 drives the first pulley 9 to rotate through the belt. The first pulley 9 drives the rotating screw 5 to rotate. Since the threaded sleeve 4 is threadedly connected to the rotating screw 5, the threaded sleeve 4 will move in one direction on the surface of the rotating screw 5. On the contrary, when the rotating screw 5 rotates in the reverse direction, the threaded sleeve 4 will move in the opposite direction. Driven by the threaded sleeve 4, the slider 3 will also move accordingly. Then the slider 3 drives the outer hoop 7 to move, and the outer hoop 7 drives the inner hoop 6 to move. At the same time, all the injectors 8 installed on the outer hoop 7 will also move with the outer hoop 7. It should be noted that the oil pipe connected to the injector 8 is a flexible pipe, so it will not affect the working movement of the injector 8. In this way, the outer hoop 7 and the inner hoop 6 drive the injector 8 to move from one end of the plate roller body 16 to the other end. During this process, the injector 8 will continuously spray the oil fluid on the surface of the plate roller body 16 to achieve the purpose of automatically lubricating the plate roller. Among them, the stepping motor 10 is fixedly installed on the corresponding side of the frame 17, and when the stepping motor 10 works, it drives the second pulley 11 to rotate. The second pulley 11 drives the first pulley 9 to rotate through the belt. The first pulley 9 drives the rotating screw 5 to rotate, so that the lubrication work can be automatically carried out according to the working frequency of the machine, improving the lubrication efficiency of the plate roller and providing convenience for the user's work. It should be noted that according to actual usage requirements, the second pulley 11 and the stepping motor 10 can also be removed, and then the rotating screw 5 can be manually rotated to work, realizing the emergency oiling operation in a special working environment and providing convenience for the user's work. As the plate roller body 16 rotates, the product will be conveyed forward. Among them, the plate roller body 16 is used for printing and processing the packaging. It should be noted that the plate roller body 16 is driven by a machine to work automatically. That is to say, a motor is installed on one side of the machine, and then gears are installed on the motor and at one end of the plate roller body 16 outside the fixed frame 15. Then the two gears are connected by a chain drive, and thus the automatic work of the plate roller body 16 can be realized, providing convenience for the user's work. This is the prior art and will not be described in detail in the text. During the conveying process of the product, the two flattening components 18 are simultaneously pressed on the surface of the product. The flattening component 18 is used to press on the surface of the product and can flatten the product during the conveying process of the product, preventing the product from wrinkling during the processing process, ensuring the flatness of the surface processing of the product, and improving the quality of the product production and processing. During the work, the flattening plate 183 contacts the surface of the product. The flattening arm 182 is installed in the adjustable bracket 181 and is not easily moved upward under the pulling of the second spring 184.Furthermore, it can ensure that the pressing plate 183 is always pressed flat on the product surface, and at the same time, it will not be too "rigid" to damage the product. The frame 17 is the supporting part of the machine, and a cross bar is installed between the two frames 17 for installing the flattening component 18, which also enables the flattening component 18 to adjust its working position on the cross bar according to actual working requirements, providing convenience for the user's work. This is the prior art and will not be elaborated in detail in this article. The first spring 14 functions to reset the latch 13 during operation. When the slider 3 moves, the top of the latch 13 will insert into the corresponding groove opened on the inner side of the slider 3, thus achieving the positioning of the slider 3 and preventing the slider 3 from moving randomly, as well as preventing the outer hoop 7 from moving randomly. Among them, when the slider 3 moves on the surface of the slide rail 2, its inner wall will first squeeze the latch 13 into the corresponding sliding hole 12, and at the same time compress the first spring 14. When the groove inside the slider 3 aligns with the latch 13 at the current position, under the action of the first spring 14, the latch 13 will pop out of the inner cavity of the sliding hole 12 and snap into the groove, realizing the positioning of the slider 3. After the lubrication work is completed, the stepping motor 10 drives the rotating screw 5 to rotate in the reverse direction, pulling the outer hoop 7 back to its original position and preparing for the next lubrication work. It should be noted that according to actual working requirements, the width of the pressing plate 183 can also be widened as long as it can meet the actual working requirements.
[0029] Therefore, the structural design of automatically lubricating the printing plate cylinder is adopted, and the oiling work can be completed during the normal operation of the plate cylinder and the interval gap between the front and back connections of the plastic packaging, without the need to pause the machine, and the printing work can proceed continuously, saving a large amount of time, improving the production efficiency of printed products, and providing convenience for the user's work.
[0030] Both sides of the top of the base 1 are fixedly connected with fixing frames 15, and a plate cylinder body 16 located inside the inner hoop 6 is rotatably installed between the two fixing frames 15.
[0031] Specifically, with the setting of the fixing frame 15 and the plate cylinder body 16, the plate cylinder body 16 is used for printing and processing the packaging. It should be noted that the plate cylinder body 16 is driven to work automatically by the machine. That is to say, a motor is installed on one side of the machine, and then gears are installed on the motor and the end of the plate cylinder body 16 located outside the fixing frame 15, and then the two gears are connected by a chain drive, thereby enabling the automatic work of the plate cylinder body 16, providing convenience for the user's work. This is the prior art and will not be elaborated in detail in this article.
[0032] A frame 17 is fixedly installed on the outside of the fixing frame 15. A stepping motor 10 is fixedly installed on the inner side of one of the frames 17. The output shaft of the stepping motor 10 is fixedly installed with a second pulley 11, and the first pulley 9 is connected to the second pulley 11 by a belt drive.
[0033] Specifically, with the settings of the frame 17, the stepping motor 10, and the second pulley 11, the stepping motor 10 is fixedly installed on the corresponding side of the frame 17. When the stepping motor 10 works, it drives the second pulley 11 to rotate. The second pulley 11 drives the first pulley 9 to rotate through the belt, and the first pulley 9 drives the rotating screw 5 to rotate, so that the lubrication work can be automatically carried out according to the working frequency of the machine, improving the lubrication efficiency of the plate cylinder and providing convenience for the user's work. It should be noted that according to actual use requirements, the second pulley 11 and the stepping motor 10 can also be removed, and the rotating screw 5 can be manually rotated to work, realizing the emergency oiling operation in a special working environment and providing convenience for the user's work.
[0034] A plurality of sliding holes 12 are formed in the top of the slide rail 2. A retaining pin 13 is slidably installed inside the sliding hole 12. The top end of the retaining pin 13 is inserted into the inner wall of the corresponding side of the slider 3. The bottom end of the retaining pin 13 is fixedly connected to a first spring 14. The end of the first spring 14 away from the retaining pin 13 is fixedly connected to the inner wall of the sliding hole 12.
[0035] Specifically, with the settings of the sliding hole 12, the retaining pin 13, and the first spring 14, the first spring 14 functions to reset the retaining pin 13 during operation. When the slider 3 moves, the top end of the retaining pin 13 will be inserted into the groove formed in the corresponding side of the slider 3, thus enabling the positioning of the slider 3 and preventing the slider 3 from moving randomly, and also preventing the outer hoop 7 from moving randomly. Among them, when the slider 3 moves on the surface of the slide rail 2, its inner wall will first squeeze the retaining pin 13 into the corresponding sliding hole 12, and at the same time compress the first spring 14. When the groove inside the slider 3 is aligned with the retaining pin 13 at the current position, under the action of the first spring 14, the retaining pin 13 will be ejected from the inner cavity of the sliding hole 12 and snapped into the groove, realizing the positioning of the slider 3.
[0036] A plurality of flattening assemblies 18 are detachably installed on one side between the two frames 17. The flattening assemblies 18 are at the same height as the plate cylinder body 16.
[0037] Specifically, with the setting of the frame 17, the frame 17 is the supporting part of the machine. A cross bar is also installed between the two frames 17 for installing the flattening assemblies 18, and it also enables the flattening assemblies 18 to adjust their working positions on the cross bar according to actual working requirements, providing convenience for the user's work. This is prior art and will not be elaborated much in the text.
[0038] The flattening assembly 18 includes an adjustable bracket 181 fixedly installed inside two frames 17. An embeddable and movable flattening arm 182 is installed on the top of the adjustable bracket 181. A second spring 184 is fixedly connected to the bottom of the flattening arm 182. One end of the second spring 184 away from the flattening arm 182 is fixedly connected to the inner wall of the adjustable bracket 181. One end of the flattening arm 182 is fixedly connected to a flattening plate 183 located outside the adjustable bracket 181.
[0039] Specifically, with the arrangements of the frame 17 and the flattening assembly 18, the flattening assembly 18 is used to press on the surface of the product. It can flatten the product during the product conveying process, prevent the product from wrinkling during the processing, ensure the flatness of the product surface during processing, improve the quality of product production and processing. During operation, the flattening plate 183 contacts the product surface. The flattening arm 182 is installed in the adjustable bracket 181 and is not easily movable upward under the pulling of the second spring 184. Thus, it can ensure that the flattening plate 183 always presses flat on the product surface and will not be too "rigid" to damage the product.
