[0002] With the rapid development of crystal label printing technology, the market has placed higher demands on the printing quality, production efficiency, and application scope of crystal label products. The structural design of traditional crystal label printing rollers is gradually failing to meet the current large-scale and diversified production needs.

[0003] The existing printing rollers, when used with crystal label substrates of different sizes and thicknesses, are difficult to adjust due to their fixed installation method. Operators need to spend a lot of time disassembling and adjusting the printing rollers to adapt to new printing specifications. This not only interrupts the production process, but also easily affects the printing quality due to adjustment errors, resulting in substrate waste. In addition, during long-term continuous printing operations, ink residue is easily accumulated on the surface of the printing rollers. Existing cleaning methods require disassembly and cleaning after stopping the machine, which will cause wear on the surface of the printing rollers due to frequent disassembly and shorten the service life of the equipment.

[0004] Therefore, it is necessary to provide a new crystal label printing roller to solve the above-mentioned technical problems. Utility Model Content

Detailed Implementation

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5As shown, a crystal label printing roller includes a protective box 1 and a feed inlet 2. The feed inlet 2 is located on one side of the protective box 1, and a discharge outlet 3 is located on the other side of the protective box 1. A printing roller body 4 is fixedly connected to the inner wall of the protective box 1. There are two printing roller bodies 4. One printing roller body 4 is made of chrome-plated carbon steel with an engraved intaglio pattern on its surface, and the other printing roller body 4 is made of nitrile rubber. An adjusting component 5 is located on one side of the printing roller body 4. The adjusting component 5 includes a first bevel gear 51 fixedly connected to one end of the printing roller body 4. The protective box 1... The inner wall of the protective box 1 is slidably connected to a positioning plate 52; the adjusting component 5 also includes a cylinder 53 fixedly installed at the bottom of the protective box 1, the piston rod of the cylinder 53 being fixedly connected to the top of the positioning plate 52; the adjusting component 5 also includes a transmission rod 54 rotatably connected to the inner wall of the protective box 1, a second bevel gear 55 being fixedly connected to the surface of the transmission rod 54, the teeth on the surface of the second bevel gear 55 meshing with the teeth on the surface of the first bevel gear 51; the adjusting component 5 also includes a first motor 56 fixedly installed at the top of the protective box 1, the output end of the first motor 56 being fixedly connected to one end of the transmission rod 54;Two second bevel gears 55 are provided. One of the second bevel gears 55 is slidably connected to the transmission rod 54 and fixedly connected to one end of the positioning plate 52. The surface of the transmission rod 54 is provided with a slide rail. The second bevel gear 55 can slide on the surface of the transmission rod 54 and rotate with the transmission rod 54. One end of the positioning plate 52 is slidably connected to the transmission rod 54 through a support block. Two printing roller bodies 4 are provided, each fixedly connected to a first bevel gear 51. One of the printing roller bodies 4 is fixedly installed on the surface of the positioning plate 52. The protective box 1 serves as the outer shell of the entire device, protecting the internal printing roller body 4, adjusting parts 5, and cleaning parts 6 from external dust and debris, and providing installation reference and structural support to form a relatively closed printing environment and ensure... The stability of the crystal label printing process is ensured. The protective box 1 contains an ink cartridge and a UV curing lamp. The feed port 2 is used to feed the crystal label substrate into the equipment, serving as the material entry point for the printing process. The discharge port 3 is used to discharge the printed crystal label, achieving the output of the finished product. The printing roller body 4 is the core printing component, with printed patterns and designs on its surface. Through contact and pressing with the substrate, the pattern is transferred to the crystal label, realizing the printing function. The first bevel gear 51 meshes with the second bevel gear 55, transmitting the rotational power of the transmission rod 54 to the printing roller body 4, achieving rotational adjustment of the printing roller. The positioning plate 52 supports one of the printing roller bodies 4, and the distance between the two printing roller bodies 4 can be changed by sliding to adapt to different... The thick crystal label substrate, in conjunction with cylinder 53 and the second bevel gear 55, achieves synchronized adjustment of position and power. Cylinder 53, through the extension and retraction of its piston rod, drives positioning plate 52 to slide within protective box 1, thereby adjusting the distance between the two printing roller bodies 4 and controlling printing pressure. Transmission rod 54 transmits the torque of the first motor 56 to the second bevel gear 55, while simultaneously providing sliding support for the second bevel gear 55 on positioning plate 52, achieving compatibility between power transmission and position adjustment. The second bevel gear 55, through meshing with the first bevel gear 51, converts the rotation of transmission rod 54 into the rotation of the printing roller body 4. The design of two second bevel gears 55 allows simultaneous driving of two printing roller bodies 4, ensuring printing synchronization. The first motor 56 serves as an adjusting component. 5 provides a power source, driving the transmission rod 54 to rotate, thereby adjusting the speed of the printing roller body 4 to meet the needs of different printing processes. It should be noted that cylinder 53 works in conjunction with an air compressor, air tank, filter pressure reducing valve, directional control valve, and flow control valve. During operation, the air compressor compresses ambient air to a set pressure and stores it in the air tank. The filter pressure reducing valve further purifies the air and stabilizes the pressure before delivering it to the control valve via an air pipe. The directional control valve switches the airflow channel according to an electrical signal, determining the extension and retraction direction of cylinder 53. The flow control valve adjusts the airflow speed, controlling the movement speed of cylinder 53. Compressed air enters either the rod-side or rodless-side chamber of cylinder 53, pushing the piston to move. The piston drives the piston rod to output linear reciprocating motion.

[0018] The cleaning component 6 is disposed inside the protective box 1. The cleaning component 6 includes reciprocating rollers 61 rotatably connected to both sides of the protective box 1, with a spline sleeve 62 slidably connected to the surface of the reciprocating rollers 61. A crescent pin is provided on the inner wall of the spline sleeve 62, and the crescent pin inside the spline sleeve 62 engages with the roller pattern on the surface of the reciprocating rollers 61. The cleaning component 6 also includes a limiting rod 63 fixedly connected to the surface of the spline sleeve 62. A limiting groove is provided on the side of the protective box 1, and the limiting rod 63 is slidably connected to the surface of the limiting groove. The cleaning component 6 also includes a cleaning brush 64 fixedly connected to the surface of the spline sleeve 62. One end of the reciprocating roller 61 penetrates the side of the protective box 1 and is fixedly connected to the output end of the second motor 65. The roller pattern on the surface of the reciprocating roller 61 is a bidirectional spiral groove that engages with the crescent pin inside the spline sleeve 62, thus controlling the output of the second motor 65. The rotation is converted into the reciprocating linear motion of the spline sleeve 62. The crescent pin on the inner wall of the spline sleeve 62 engages with the roller pattern of the reciprocating roller 61 to achieve sliding motion, which drives the cleaning brush 64 to move back and forth along the axis of the printing roller. The limiting rod 63 is slidably connected in the limiting groove of the protective box 1 to limit the movement direction of the spline sleeve 62 and prevent it from deviating, ensuring the fit and stability of the cleaning brush 64 with the printing roller body 4. When the cleaning brush 64 moves back and forth with the spline sleeve 62, it wipes the surface of the printing roller body 4 to remove residual impurities. The cleaning brush 64 only fits the printing roller body 4 when cleaning. When the printing roller body 4 is working, the cleaning brush 64 is placed on one side of the printing roller body 4. The second motor 65 provides power to the cleaning component 6, driving the reciprocating roller 61 to rotate, thereby realizing the automatic reciprocating cleaning of the cleaning brush 64.

[0019] Working principle: During use, based on the thickness of the crystal label substrate to be printed, the piston rod is extended and retracted by the cylinder 53, causing the positioning plate 52 to slide along the inner wall of the protective box 1. The nitrile rubber printing roller body 4 carried by the positioning plate 52 moves accordingly, adjusting the distance between it and the fixed carbon steel chrome-plated printing roller body 4 to a suitable value. At the same time, the sliding second bevel gear 55 on the surface of the transmission rod 54 moves with the positioning plate 52, always meshing with the first bevel gear 51 of the nitrile rubber roller to ensure uninterrupted power transmission. At this time, the first motor 56 is started, driving the transmission rod 54 to rotate. The two second bevel gears 55 drive the first bevel gears 51 of the double rollers to rotate, so that the double rollers reach the set speed synchronously. The ink cartridge in the protective box 1 starts the ink supply mode, and the ink is delivered to the surface of the carbon steel chrome-plated roller through the built-in channel. Its intaglio pattern is naturally filled with ink, and the initial ink transfer preparation is completed. The cleaning brush 64 of the cleaning component 6 is then checked. In the reset state, to avoid interfering with ink transfer, the UV curing lamp is turned on for preheating to ensure rapid curing of the ink after printing. When the equipment is ready, the substrate enters the protective box 1 from the feed port 2 and enters the space between the two rollers with the assistance of the internal hidden guide structure. At this time, the two rollers are rotating synchronously. The carbon steel chrome-plated roller drives the substrate to move through surface friction, while the nitrile rubber roller rotates passively with the substrate to avoid stretching or wrinkling of the substrate. When the substrate passes through the gap between the two rollers, the nitrile rubber roller deforms slightly under the pressure of the cylinder 53, pressing the substrate tightly onto the surface of the carbon steel chrome-plated roller. The ink in the intaglio pattern is completely transferred to the substrate to form the corresponding pattern. Thanks to the high hardness of the carbon steel chrome-plated roller and the flexible pressing of the nitrile rubber roller, problems such as false printing and broken lines are effectively avoided. In addition, the ink box is continuously replenished with ink to achieve continuous printing. The substrate with completed ink transfer is shaped in the UV curing lamp area and output as a finished product from the discharge port 3. When a single batch of printing is completed or the machine is stopped, the second motor 65 of the cleaning component 6 is started, driving the reciprocating roller 61 to rotate. The bidirectional spiral groove on the surface of the reciprocating roller 61 engages with the crescent pin on the inner wall of the spline sleeve 62, which is converted into the axial reciprocating motion of the spline sleeve 62. The limit rod 63 slides along the limit groove on the side of the protective box 1 to prevent deviation. The cleaning brush 64 on the surface of the spline sleeve 62 moves accordingly to wipe the surface of the two rollers, remove ink residue in the texture of the carbon steel chrome-plated roller and trace amounts of ink on the surface of the nitrile rubber roller, so as to avoid affecting the next printing.
