Description

Technical Field

[0001] The utility model relates to the technical field of embossing rollers, in particular to an embossing roller for a water-ink carton. Background Art

[0002] An embossing roller, also known as an embossing cylinder, is a roller with a pattern or texture on its surface. An embossing roller is usually made of metal, rubber or plastic and works by applying a certain amount of pressure and heat to the material to produce the desired pattern or texture on the surface of the material. The pattern of the embossing roller can be customized as needed to meet the needs of different industries and individuals.

[0003] When the conventional embossing roller rotates, various factors (such as mechanical installation error, bearing wear, etc.) may cause slight deviations in the axis. For the ink painting embossing roller, due to its complex and fine surface pattern, if these deviations cannot be solved, the embossing printing of the ink painting will be inaccurate and intricate. Therefore, a new ink carton embossing roller is proposed to solve the above problem. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0005] Therefore, one purpose of the utility model is to provide a water-ink carton embossing roller to solve the problems mentioned in the background technology and overcome the shortcomings of the prior art.

[0006] In order to achieve the above-mentioned purpose, an embodiment of one aspect of the utility model provides a water-ink carton embossing plate roller, comprising a roller body and an outer layer, wherein the outer surface of the roller body is provided with the outer layer, the two ends of the roller body are fixedly connected with a main shaft, and the two sides of the roller body are provided with bearings;

[0007] The main shaft is installed in the bearing, and the end of the roller body is provided with a circle of grooves;

[0008] The outer surface of the main shaft is sleeved with a coupling, and the coupling is formed by connecting left-right symmetrical couplings;

[0009] The gaps between the couplings are filled with flexible blocks;

[0010] The coupling and the main shaft are provided with pin holes.

[0011] Preferably, in any of the above schemes, the roller body is made of stainless steel, and the outer layer is specifically an electroplated copper layer.

[0012] This device is specially used for embossing printing of ink patterns on carton boards.

[0013] One coupling of the coupling is connected to the output end of the motor. That is, the output end of the motor is inserted into the coupling, and the bolt pin is inserted vertically in the pin hole and fastened with a nut. Similarly, the main shaft is inserted into the coupling, and the bolt pin is inserted vertically in the pin hole and fastened with a nut. When the motor is working, the roller body is driven to rotate through the coupling, and the surface of the plate roller is engraved or etched into a shape opposite to the required pattern, that is, the pattern part is engraved into a depression, and the non-pattern part remains flat. During the printing process, water-based ink is evenly applied to the surface of the plate roller. Due to the depression of the pattern part on the plate roller, there will be relatively more ink in these parts, while there will be less ink in the non-pattern part. The plate roller rotates on the printing press and contacts the surface of the carton to be printed. During the contact process, due to the pressure between the depressed parts on the plate roller and the surface of the carton, the ink in these parts is transferred to the carton. As the plate roller continues to rotate and the carton moves forward, the ink is gradually transferred from the plate roller to the carton to form the required water-based ink pattern. At the same time, the ink is quickly dried and fixed through the drying device on the printing press, ensuring that the pattern remains on the carton for a long time without falling off.

[0014] Adopting the above technical scheme: the core structure of the device is: groove, coupling, coupling, flexible block, pin hole. The coupling is composed of two couplings, and the gap between the couplings is filled with a flexible block. The flexible block is engineering plastic and is a flexible material. Therefore, the coupling is an elastic coupling. For the ink painting embossing roller, due to its complex and fine surface pattern, it is particularly important to improve the embossing accuracy. With the elastic coupling, the ink printing roller may cause slight deviations of the axis during operation due to various factors (such as mechanical installation errors, bearing wear, etc.). The elastic coupling can effectively compensate for these deviations and reduce the misalignment between the axes due to its unique elastic design. At the same time, its elastic characteristics can also effectively absorb and reduce vibrations, thereby reducing the embossing error caused by vibration and improving the embossing accuracy. To reduce the impact of equipment vibration and impact on embossing accuracy. The elastic coupling can convert these shocks and vibrations into heat energy or other forms of energy through its flexible block, thereby achieving the effect of buffering and shock absorption. This helps maintain stable operation of the plate roller and reduces the degradation of embossing quality caused by shock and vibration.

[0015] Since the embossing roller may be contaminated with ink, paint or other impurities during use, this circle of grooves helps to remove the residual substances accumulated at the end of the roller more easily during cleaning, reducing the difficulty of cleaning and improving cleaning efficiency. The end of the embossing roller may contact or rub against other parts of the machine. This circle of grooves can act as a buffer to reduce direct friction and protect the roller end from damage. For some production lines with a high degree of automation, the end face grooves of the embossing roller can also be used as identification or positioning points to achieve automatic installation, removal or position adjustment of the roller.

[0016] Preferably, any of the above solutions has rounded corners on the edges of the end faces of the roller body.

[0017] Preferably, any of the above schemes is that the coupling of the coupling is made of aluminum alloy, between the couplings.

[0018] Preferably, any of the above solutions is that the flexible block is made of plastic material, a bolt pin can be inserted into the pin hole and a nut is threadedly connected to the end of the bolt pin.

[0019] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0020] 1. The ink-water carton embossing roller is arranged by the matching of grooves, couplings, couplings, flexible blocks, and pin holes. The coupling is composed of two couplings.

The elastic coupling can convert these impacts and vibrations into heat energy or other forms of energy through its flexible block, thereby achieving the effect of buffering and shock absorption. This helps maintain stable operation of the plate roller and reduces the degradation of embossing quality caused by shock and vibration.

[0021] 2. Since the embossing roller may be contaminated with ink, paint or other impurities during use, this circle of grooves helps to remove the residual substances accumulated at the end of the roller more easily during cleaning, reducing the difficulty of cleaning and improving cleaning efficiency. The end of the embossing roller may contact or rub against other parts of the machine. This circle of grooves can act as a buffer to reduce direct friction and protect the roller end from damage.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] The outer surface of the main shaft 3 is sleeved with a coupling 6, which is formed by connecting two symmetrical couplings 7;

[0033] The gaps between the couplings 7 are filled with flexible blocks 8;

[0034] The coupling 7 and the main shaft 3 are provided with pin holes 9 .

[0035] Preferably, in any of the above schemes, the roller body 1 is made of stainless steel, and the outer layer 2 is specifically an electroplated copper layer.

[0036] Embodiment 1: This device is specially used for embossing ink patterns on carton boards. The edge of the end face of the roller body 1 is rounded. The material of the coupling 7 of the coupling 6 is aluminum alloy, and the coupling 7 is between.

[0037] Embodiment 2: The flexible block 8 is made of plastic, and a bolt pin can be inserted into the pin hole 9 and a nut can be threadedly connected at the end of the bolt pin. The flexible block 8 is engineering plastic and is a flexible material, so the coupling 6 is an elastic coupling. For the ink painting embossing roller, due to its complex and fine surface pattern, it is particularly important to improve the embossing accuracy. With the elastic coupling 6, the ink printing roller may cause slight deviations of the axis during operation due to various factors (such as mechanical installation errors, bearing wear, etc.). The elastic coupling can effectively compensate for these deviations and reduce the misalignment between the axes due to its unique elastic design.

[0038] The working principle of the utility model is as follows:

[0039] A coupling 7 of the coupling 6 is connected to the output end of the motor. That is, the output end of the motor is inserted into the coupling 7, and the bolt pin is inserted vertically in the pin hole 9 and fastened with a nut. Similarly, the main shaft 3 is inserted into the coupling 7, and the bolt pin is inserted vertically in the pin hole 9 and fastened with a nut. When the motor is working, the roller body 1 is driven to rotate through the coupling 6, and the surface of the plate roller is engraved or etched into a shape opposite to the desired pattern, that is, the pattern part is engraved into a depression, and the non-pattern part remains flat. During the printing process, the ink is evenly applied to the surface of the plate roller. Due to the depression of the pattern part on the plate roller, the ink in these parts will be relatively more, while the ink in the non-pattern part will be less. The plate roller rotates on the printing press and contacts the surface of the carton to be printed. During the contact process, due to the pressure between the depression on the plate roller and the surface of the carton, the ink in these parts is transferred to the carton. As the plate roller continues to rotate and the carton moves forward, the ink is gradually transferred from the plate roller to the carton to form the desired ink pattern. At the same time, the ink is quickly dried and fixed by the drying device on the printing press to ensure that the pattern will last on the carton.

The coupling 6 is composed of two couplings 7. The gap between the couplings 7 is filled with a flexible block 8. The flexible block 8 is engineering plastic and is a flexible material. Therefore, the coupling 6 is an elastic coupling. For the ink-water painting embossing roller, it is particularly important to improve the embossing accuracy due to its complex and fine surface pattern. With the elastic coupling 6, the ink-water printing roller may cause a slight deviation of the axis during operation due to various factors (such as mechanical installation error, bearing wear, etc.). The elastic coupling can effectively compensate for these deviations and reduce the misalignment phenomenon between the axes due to its unique elastic design. At the same time, its elastic characteristics can also effectively absorb and reduce vibration, thereby reducing the embossing error caused by vibration and improving the embossing accuracy. To reduce the influence of equipment vibration and impact on the embossing accuracy. The elastic coupling 6 can convert these impacts and vibrations into heat energy or other forms of energy through its flexible block 8, thereby achieving the effect of buffering and shock absorption. This helps maintain stable operation of the plate roller and reduces the degradation of embossing quality caused by shock and vibration.
