[0002] Each blade needs to print enterprise LOGO, model data and other patterns on its two planes after production, as identification and distinction. In the prior art, a vertical pad printing machine is generally used to complete the printing of patterns, so that the blade needs to be manually turned over after printing one side and then the other side is printed, which is low in printing efficiency.

[0008] As preferred, it further comprises push-pull doors I; the protective shell is provided with two push-pull doors I.

[0009] As preferred, the push-pull door I is made of flexible transparent material.

[0010] As preferred, it further comprises push-pull doors II; the protective shell is provided with two push-pull doors II.

[0011] As preferred, it further comprises supporting plates, guide rods, elastic members II, fixed plates, water inlet pipes II, conduits and a drain pipe; the upper and lower portions of the mounting plate are fixedly connected with two supporting plates; each two corresponding supporting plates are fixedly connected with two guide rods; each two corresponding supporting plates are fixedly connected with two elastic members II on the opposite sides; each guide rod passes through the corresponding two elastic members II; all the guide rods are slidably connected with two fixed plates; each fixed plate is fixedly connected with corresponding elastic members II; each water outlet pipe is connected with one water inlet pipe II; each water inlet pipe II is connected with a plurality of conduits; each fixed plate is fixedly connected with corresponding conduits; and the front ends of all the conduits are connected with the drain pipe.

[0014] The beneficial effects of this invention are as follows: 1. This invention transfers ink to the pad printing roller through contact between the pad printing roller and the ink roller, and then transfers the ink on the pad printing roller to the blade material belt through rolling. Compared with existing vertical pad printing equipment, the printing efficiency is greatly improved. Furthermore, by setting partitions on the pad printing roller and injecting cooling water into the pad printing roller, the cooling water is injected sequentially into the fan-shaped space separated by the partitions. As the pad printing roller rotates, the circulating water flows, thereby cooling the pad printing roller and the ink roller. This prevents the heat on the pad printing roller from causing the ink to evaporate easily, resulting in ink drying and causing defects, ghosting, or other issues in the printed pattern on the blade material belt.

[0015] 2. By setting up rollers, the rollers are pressed onto the blade material strip. The fine texture of the rollers captures dust and impurities on the blade material strip, preventing dust and impurities from affecting the subsequent transfer quality. The heat in the pad printing roller is transferred to the rollers, realizing heat recovery and utilization. On this basis, the circulating water is heated and then used to heat the blade material strip, allowing the ink transferred to the blade material strip to dry quickly and adhere stably to the blade material strip, thus achieving efficient and high-quality ink transfer.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] It also includes a mounting plate 5, a reference wheel 6, an ink wheel 7, an ink cartridge 8, a hollow shaft 9, a pad printing wheel 10, a motor 11, a water inlet pipe 13, a water outlet pipe 14, a water injection pipe 15, and a drain pipe 16; the mounting plate 5 is welded inside the protective shell 2; the mounting plate 5 is rotatably connected to the reference wheel 6; the mounting plate 5 is rotatably connected to two vertically distributed ink wheels 7, each ink wheel 7 having printing grooves engraved on it; the mounting plate 5 is bolted to two vertically distributed ink cartridges 8; each ink wheel 7 mates with one ink cartridge 8, the ink wheel 7 picks up ink from the ink cartridge 8, and scrapes off excess ink at the edge of the ink cartridge 8; the mounting plate 5 is connected to two vertically distributed hollow shafts 9; each hollow shaft 9 is rotatably connected to a pad printing wheel 10; each Each pad printing roller 10 contacts and engages with an ink roller 7; two vertically distributed motors 11 are mounted on the back of the mounting plate 5; the output shaft of each motor 11 is fixedly connected to an ink roller 7; each hollow shaft 9 has a partition 9001 inside, and both the hollow shaft 9 and the partition 9001 are made of heat-insulating material; each partition 9001 divides the corresponding hollow shaft 9 into upper and lower spaces, with the lower space connected to a water inlet pipe I 13 and the upper space connected to a water outlet pipe 14; each hollow shaft 9 has two vertically symmetrically distributed through slots 9002; all water inlet pipes I 13 are connected to a water injection pipe 15; all water outlet pipes 14 are connected to a drain pipe 16, and a solenoid valve is installed inside the drain pipe 16.

[0031] The outer ring surface of the pad printing roller 10 is provided with elastic silicone. When the pad printing roller 10 comes into contact with the ink roller 7, the silicone is deformed by pressure and embedded into the printing groove of the ink roller 7, transferring the ink in the printing groove of the ink roller 7 to the pad printing roller 10.

[0032] It also includes an elastic element I12; the mounting plate 5 is slidably connected to two hollow shafts 9; the mounting plate 5 has two arc-shaped grooves 5001 distributed vertically; each hollow shaft 9 slides in one arc-shaped groove 5001; each arc-shaped groove 5001 is fixedly connected to an elastic element I12; the elastic element I12 is a spring; each elastic element I12 is fixedly connected to one hollow shaft 9.

[0033] It also includes spacers 101 and sleeves 102; each printing roller 10 has a groove inside, and several spacers 101 are fixedly connected in a ring array inside the groove. The spacers 101 are made of a high thermal conductivity material; each hollow shaft 9 has a sleeve 102 rotatably connected to its outer ring surface; each sleeve 102 is located inside a printing roller 10; each sleeve 102 is fixedly connected to a corresponding spacer 101; each sleeve 102 has several slots 10201 equidistantly opened on its side wall; each slot 10201 is located between two spacers 101.

[0034] It also includes a sliding door I3; the front of the protective shell 2 is equipped with two symmetrically arranged sliding doors I3.

[0035] The sliding door I3 is made of flexible transparent material, which makes it easy for staff to observe the transfer printing process of the blade material strip 001.

[0036] It also includes a sliding door II4; two symmetrically arranged sliding doors II4 are installed at the rear of the protective shell 2, which facilitates the replenishment of ink cartridge 8 and the maintenance of corresponding components.

[0037] The working steps of the above embodiments are as follows:

[0038] Before using this pad printing machine, the operator first opens the sliding door II4 and fills the ink cartridge 8 with ink through the reserved tube on the ink cartridge 8. Then, the operator closes the sliding door II4 again. Next, the water inlet pipe 15 and the drain pipe 16 are connected to the water circulation equipment. Then, the operator opens the sliding door I3 and inserts the traction belt through the reserved hole on the left side of the protective shell 2. After passing through the reference wheel 6, the operator manually separates the two pad printing wheels 10. Each pad printing wheel 10 drives a hollow shaft 9 to move, and the corresponding elastic element I12 is compressed. Then, the traction belt is passed between the two pad printing wheels 10 and then out through the reserved hole on the right side of the protective shell 2. The operator then resets the pad printing wheels 10, and all the elastic elements I12 are restored. The two pad printing wheels 10 hold the traction belt in place. Then, to avoid the influence of dust on the pad printing process, the operator closes the sliding door I3 again. At this time, the preparation work before pad printing is completed.

[0039] Next, fix the left end of the traction belt to the material cylinder on the external electric take-up roller, fix the material cylinder of the blade material strip 001 to the external electric unwind roller, and then connect the movable end of the blade material strip 001 to the right end of the traction belt. Finally, control the external electric unwind roller and the external electric take-up roller to tension the traction belt and the blade material strip 001. After tensioning, the traction belt is tightly against the reference wheel 6. At this time, control the external electric take-up roller to wind up the traction belt and the external electric unwind roller to unwind the blade material strip 001. Under the friction with the traction belt, the reference wheel 6 will rotate with the movement of the traction belt, indicating that the intelligent pad printing machine is in normal working condition. Then, the normal pad printing operation of the blade material strip 001 can be started. Control the start of the two motors 11. The output shaft of the motor 11 rotates and drives the ink wheel 7. Looking from front to back, the upper ink wheel 7 rotates counterclockwise, and the ink wheel 7 drives the pad printing wheel 10 to rotate. The upper pad printing wheel 10 rotates clockwise, and the lower ink wheel 7 and the reference wheel 6 rotate clockwise. The pad printing roller 10 rotates in the opposite direction. Then, the output shaft of the control motor 11, the external electric take-up roller, and the external electric unwind roller rotate synchronously. As the ink roller 7 rotates, the ink in the ink cartridge 8 adheres to the outer ring surface of the ink roller 7. When the outer ring surface of the ink roller 7 passes the edge of the ink cartridge 8, the ink cartridge 8 scrapes off the ink from the outer ring surface of the ink roller 7, excluding the printing groove. Then, during its rotation, the ink roller 7 also drives the pad printing roller 10 to rotate. When the printing groove containing ink comes into contact with the pad printing roller 10, the ink in the printing groove is transferred to the pad printing roller 10. On the printing roller 10, as the printing roller 10 rotates, when the printing roller 10 contacts the blade material strip 001, the ink is transferred onto the blade material strip 001. At this time, since the blade material strip 001 is clamped by two printing rollers 10 at the top and bottom respectively, the printing rollers 10 can simultaneously print on both the top and bottom sides of the blade material strip 001 through rotation. In addition, with the continuous rotation of the ink roller 7, the printing process continues, greatly improving the printing efficiency of the blade material strip 001.

[0040] Considering that during the printing process of the blade material strip 001, the blade material strip 001 and the printing roller 10 experience rolling friction, and the printing roller 10 and the ink roller 7 also experience rolling friction, as the printing work continues, the heat generated by the friction can easily cause the ink solvent to evaporate, leading to ink drying. This can easily cause defects or ghosting in the printed pattern on the blade material strip 001. Therefore, before printing begins, an external circulating water device injects cooling water into each inlet pipe I 13 through the water injection pipe 15, and controls the closing of the solenoid valve on the drain pipe 16. The hollow shaft 9 is divided into upper and lower spaces by the partition plate 9001. Cooling water first enters the lower space of the hollow shaft 9, and then flows out from the through groove 9002 at the bottom of the hollow shaft 9, and enters the internal space of the printing roller 10 after passing through the slot 10201. The internal space of the printing roller 10 is divided into a corresponding number of fan-shaped spaces by several partitions 101, such as... Figure 6As shown, after the lowermost fan-shaped space is filled with cooling water, the printing roller 10 is rotated so that the next slot 10201 aligns with the through groove 9002, thereby filling the fan-shaped space with water. This operation is repeated until the lower space of the printing roller 10 is filled with cooling water and the water level in the printing roller 10 is lower than the position of the partition 9001. The solenoid valve of the drain pipe 16 is then opened, and the printing operation can begin. During the printing process, the printing roller 10 rotates, synchronously driving the partition 101 on it to rotate. The adjacent partition 101 also drives the cooling water in its fan-shaped space to rotate. When the fan-shaped space filled with cooling water rotates to the uppermost position, the slot 10201 of the fan-shaped space aligns with the upper through groove. With the cooperation of 9002, the circulating water sequentially passes through the slot 10201 and the upper through slot 9002, entering the upper space of the hollow shaft 9. Then, the circulating water returns to the external circulating water equipment through the outlet pipe 14 and the drain pipe 16 to cool the circulating water. Then, it is pumped back into the water injection pipe 15. When the pad printing roller 10 rotates, when the empty fan-shaped space rotates to connect with the lower through slot 9002, the cooling water in the lower space of the hollow shaft 9 enters the fan-shaped space. Thus, through the flow of circulating water, the heat generated by the pad printing roller 10 during the working process is carried away, and the temperature of the pad printing roller 10 is kept at about 20 degrees Celsius. This prevents the heat on the pad printing roller 10 from causing the ink to evaporate easily, resulting in ink drying.

[0041] Second embodiment

[0042] Based on the first embodiment, according to Figures 1-3 , Figures 8-10 As shown, it also includes a support plate 201, guide rods 202, elastic element II 203, fixing plate 204, water inlet pipe II 205, conduit 206, and drain pipe 16; two support plates 201 are welded to the upper and lower parts of the mounting plate 5; two guide rods 202 are fixed between each pair of corresponding upper and lower support plates 201; two elastic elements II 203 are fixed to the opposite sides of each pair of corresponding upper and lower support plates 201; the elastic element II 203 is a spring; each guide rod 202 passes through the two corresponding upper and lower elastic elements II 203; all guide rods 202 are slidably connected to two upper and lower fixed plates 204; each fixed plate 204 is fixedly connected to the corresponding elastic element II 203; each water outlet pipe 14 is connected to a water inlet pipe II 205; each water inlet pipe II 205 is connected to several conduits 206; each fixing plate 204 is fixedly connected to the corresponding conduit 206; the front ends of all conduits 206 are connected to the drain pipe 16.

[0043] It also includes a roller 207; each conduit 206 is rotatably connected to a roller 207; each conduit 206 has a heating sleeve on its rear side; each conduit 206 has a groove on its side wall, and the groove is located inside the roller 207; each roller 207 is connected to the corresponding conduit 206.

[0044] Each roller 207 has a fine texture on its outer ring surface; each fixed plate 204 has a cavity and several suction ports 20401 are provided on the cavity; each suction port 20401 corresponds to one roller 207.

[0045] The working steps of the above embodiments are as follows:

[0046] Based on the first embodiment, considering that the blade strip 001 will come into contact with air during the transfer and transportation process before printing, dust and impurities in the air can easily adhere to the blade strip 001. If the blade strip 001 is covered with dust and impurities at this time, the ink that has not yet dried on the blade strip 001 will combine with the dust and impurities, making it easy for the printed pattern to not adhere tightly to the blade strip 001, resulting in low processing quality of the blade strip 001. Therefore, before the blade strip 001 is transferred, it passes through several rollers 207. When the blade strip 001 passes between the vertically and vertically symmetrically arranged rollers 207, the elastic element II 203 is compressed. Through the reaction force of the elastic element II 203, the fixing plate 204 and its corresponding parts are pressed against the blade strip 001, thereby making the vertically and vertically symmetrical rollers 207 contact the blade strip 001. During the process of the blade strip 001 moving to the left, the rollers 207 also rotate under the action of friction. The roller 207 features a fine texture that acts like a capillary, effectively capturing dust and impurities without significantly affecting its flatness. This texture allows the roller to clean the surface of the blade strip 001, resulting in higher transfer accuracy. An external air pump, connected to the cavity of the fixed plate 204 via an air pipe, extracts air from the cavity, creating negative pressure. This allows outside air to enter the cavity through the suction port 20401. As the air passes over the surface of the roller 207, dust and impurities on its surface are also drawn into the cavity and then removed by the external air pump. This ensures timely cleaning of the roller 207, preventing dust and impurities from filling in the fine texture and hindering the roller's ability to clean the blade strip 001.

[0047] Furthermore, the water outlet pipe 14 in the first embodiment is connected to the conduit 206, and then the conduit 206 is connected to the drain pipe 16. The water discharged from the water outlet pipe 14 enters the roller 207 after passing through the conduit 206, and then flows out from the roller 207 and out through the front of the conduit 206 to the drain pipe 16. This transfers some of the heat generated by the pad printing roller 10 to the roller 207, realizing heat recovery and reuse. In conjunction with the heating sleeve at the rear of the conduit 206, the water flowing into the drain pipe 16 is heated again, raising the temperature of the circulating water to about 60 degrees Celsius. This raises the temperature of the blade material strip 001 to between 40 and 60 degrees Celsius. As a result, the ink transferred to the blade material strip 001 can dry quickly, allowing the ink to adhere stably to the blade material strip 001. At the same time, the transfer speed is adjusted so that the ink does not solidify too early during the transfer process, resulting in some ink residue on the pad printing roller 10. This achieves efficient and high-quality ink transfer.

[0048] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
