Description

Technical Field

[0001] This utility model relates to the field of printing plate roller technology, specifically a gravure printing plate roller. Background Technology

[0002] Printing rollers are an important structure in the printing and printing industry. Also called steel rollers, they are a type of printing plate material composed of multiple small cylinders. During the printing process, the printing roller is the friction point between the printing press and the printing material, used to print different patterns, text, or lines. It is one of the essential tools for producing accurate and clear images. Printing rollers are widely used in the printing industry, especially in plastic packaging printing. Their multi-color continuous printing capability gives them a unique advantage in packaging printing. Furthermore, printing rollers are often used in the plate-making process, serving as an important tool for producing high-quality printed materials. During operation, the printing roller needs to rotate continuously to leave its mark on the paper. Over time, the printing roller will heat up; if the temperature exceeds a certain value, it will affect the printing quality and shorten the roller's lifespan. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a gravure printing roller to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0005] This utility model provides a gravure printing roller, including a roller body and a cover plate. One end of the roller body is open and the inside is hollow. The cover plate is detachably installed at the open end of the roller body. A shaft is provided at the center of the end of the roller body away from the cover plate. A shaft is provided at the center of the side of the cover plate away from the roller body. The surface of the roller body is provided with multiple printing patterns.

[0006] The cover plate has an inlet pipe and an outlet pipe symmetrically arranged on its front side. Both the inlet pipe and the outlet pipe are connected to the inside of the roller body. The inlet pipe and the outlet pipe are symmetrically distributed on both sides of the shaft. Valves are provided on the inlet pipe and the outlet pipe.

[0007] A mounting groove is provided on the upper front of the cover plate, and a display module is embedded in the mounting groove. A temperature sensor is provided on the back of the display module near the opening of the roller.

[0008] Preferably, a gasket ring is provided on the inner wall of the open end of the roller body, and a sealing ring is provided on the side of the cover plate near the open end of the roller body. When the cover plate is installed at the open position of the roller body, the sealing ring abuts against the gasket ring.

[0009] Preferably, the open end of the roller body has a plurality of screw holes on its front edge, and the cover plate has a plurality of through holes near its edge on its front side. When the cover plate is located at the open end of the roller body, the through holes are aligned with the screw holes.

[0010] Preferably, the number of through holes and screw holes is the same, and the screw holes are evenly distributed around the open end of the roller body at equal intervals, while the through holes are evenly distributed around the front edge of the cover plate at equal intervals.

[0011] Preferably, the plurality of printed patterns are evenly distributed at equal intervals along the length and circumferential directions of the roller surface.

[0012] Preferably, the widths of the gasket and the sealing ring are the same.

[0013] Preferably, the central axis of the shaft on the roller body is flush with the central axis of the shaft on the cover plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] When the cover plate is located at the open position on the left end of the roller body, use a bolt to pass through the through hole and then screw the bolt into the screw hole. In this way, the cover plate is placed at the open position of the roller body. During the process of screwing the bolt into the screw hole, the sealing ring can fit against the gasket. The sealing ring is made of rubber, so the sealing ring can be slightly squeezed, and the sealing performance at the connection between the cover plate and the roller body is good.

[0016] The entire device can be installed on a printing press via a shaft at one end of the roller and a shaft on one side of the cover plate. When the roller rotates slowly to print, the printing pattern can be printed on the paperboard. The inlet pipe is connected to the inlet hose, and the outlet pipe is connected to the outlet hose, so that the roller is always filled with cooling water. As the roller rotates and prints, the heat generated by the roller itself can be transferred to the water. As water slowly flows in through the inlet pipe and slowly flows out through the outlet pipe, the heat generated by the roller can be carried away.

[0017] The temperature sensor can detect the temperature of the water inside the roller in real time, and the temperature can be displayed on the display module. When the temperature is high, it can adjust the water inlet flow rate and the water outlet flow rate to control the working temperature of the roller itself within a suitable temperature range, so as to ensure the printing quality.

[0024] like Figure 1-3 As shown, a gravure printing roller includes a roller body 1 and a cover plate 2. One end of the roller body 1 is open and the inside is hollow. The cover plate 2 is detachably installed at the open end of the roller body 1. A shaft 3 is provided at the center of the end of the roller body 1 away from the cover plate 2. A shaft 3 is provided at the center of the side of the cover plate 2 away from the roller body 1. A plurality of printing patterns 11 are provided on the surface of the roller body 1.

[0025] The front of the cover plate 2 is symmetrically provided with an inlet pipe 22 and an outlet pipe 23. Both the inlet pipe 22 and the outlet pipe 23 are connected to the inside of the roller body 1. The inlet pipe 22 and the outlet pipe 23 are symmetrically distributed on both sides of the shaft 3. A valve 24 is provided on the inlet pipe 22 and the outlet pipe 23.

[0026] A mounting groove is provided on the upper front of the cover plate 2, and a display module 25 is embedded in the mounting groove. A temperature sensor 26 is provided on the back of the display module 25 near the opening of the roller body 1.

[0027] A gasket 13 is provided on the inner wall of the open end of the roller body 1, and a sealing ring 27 is provided on the side of the cover plate 2 near the open end of the roller body 1. When the cover plate 2 is installed in the open position of the roller body 1, the sealing ring 27 is attached to the gasket 13.

[0028] The open end of the roller body 1 has multiple screw holes 12 on its front edge, and the cover plate 2 has multiple through holes 21 near its edge on its front side. When the cover plate 2 is located at the open end of the roller body 1, the through holes 21 are aligned with the screw holes 12.

[0029] The number of through holes 21 is the same as the number of screw holes 12. Multiple screw holes 12 are evenly distributed around the open end of the roller body 1 at equal intervals, and multiple through holes 21 are evenly distributed around the front edge of the cover plate 2 at equal intervals.

[0030] Multiple printed patterns 11 are evenly distributed at equal intervals along the length and circumference of the roller body 1 surface.

[0031] The widths of gasket 13 and sealing ring 27 are the same.

[0032] The shaft 3 on roller 1 is aligned with the central axis of the shaft 3 on cover plate 2.

[0033] In summary: When the cover plate 2 is located at the open position on the left end of the roller body 1, the bolt is passed through the through hole 21 and then screwed into the screw hole 12. In this way, the cover plate 2 is positioned at the open position of the roller body 1. During the process of screwing the bolt into the screw hole 12, the sealing ring 27 can fit against the gasket 13. The sealing ring 27 is made of rubber, so the sealing ring 13 can be slightly compressed, and the sealing performance at the connection between the cover plate 2 and the roller body 1 is good.

[0034] The entire device can be installed on a printing press via the shaft 3 at one end of the roller body 1 and the shaft 3 on one side of the cover plate 2. When the roller body 1 rotates slowly for printing, the printing pattern 11 can be printed on the paperboard. The water inlet pipe 22 is connected to the water inlet hose, and the water outlet pipe 23 is connected to the water outlet hose. In this way, the roller body 1 is always filled with cooling water. As the roller body 1 rotates for printing, the heat generated by the roller body 1 itself can be transferred to the water. As water slowly flows in through the water inlet pipe 22 and slowly flows out through the water outlet pipe 23, the heat generated by the roller body 1 can be carried away.

[0035] Temperature sensor 26 can detect the temperature of the water inside roller 1 in real time, and the temperature can be displayed on display module 25 in real time. When the temperature is high, it can adjust the water inlet flow rate of inlet pipe 22 and the water outlet flow rate of outlet pipe 23. This can control the working temperature of roller 1 itself within a suitable temperature range to ensure the printing quality.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
