Description

Technical Field

[0001] This utility model relates to the field of anilox roller technology, specifically to an anilox roller power transmission mechanism. Background Technology

[0002] An anilox roller is a type of roller used in printing or coating processes. The surface of the roller is engraved with fine patterns or pits. The shape, size, and depth of these patterns or pits affect the transfer and coating effect of ink or paint, making it an indispensable component in printing. During the printing process, the anilox roller contacts the printing plate or substrate, uniformly coating the ink or paint onto its outer surface to achieve image or coating transfer. Therefore, the quality and performance of the anilox roller have a significant impact on printing quality and production efficiency. Thus, proper maintenance and upkeep are essential when using anilox rollers. Regular cleaning and inspection of the anilox pattern are necessary to ensure normal operation and good printing results. However, when assembling or disassembling anilox rollers, the connection between the motor and the roller is often via pin or key drive, which is relatively unstable and difficult to install and disassemble. Utility Model Content

[0003] The purpose of this utility model is to provide a power transmission mechanism for anilox rollers, so as to solve the problem mentioned in the background art that most anilox rollers use pin drive or key drive, which is inconvenient for assembly and disassembly.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a power transmission mechanism for an anilox roller, comprising a female roller head, the female roller head being a barrel-shaped design, and an insertion point being provided on one end side surface of the female roller head; a male roller head being inserted into the side surface of the female roller head away from the insertion point, and the outer surface of the male roller head being a hexagonal design; an insertion fastening structure being provided between the female roller head and the male roller head, the female roller head and the male roller head being securely inserted through the insertion fastening structure, enabling the female roller head to transmit power to the male roller head.

[0005] Preferably, the insertion fastening structure includes: a hexagonal concave-convex platform, the end of the hexagonal concave-convex platform near the female roller head is provided with a chamfer, the end of the female roller head near the male roller head is provided with an insertion groove, and the insertion groove is inserted into the hexagonal concave-convex platform. The hexagonal concave-convex platform and the insertion groove are designed to be inclined, and the outer surface of the insertion groove is in close contact with the outer surface of the hexagonal concave-convex platform.

[0006] By adopting the above technical solution, through the inclined design of the hexagonal concave-convex platform and the insertion groove, the hexagonal concave-convex platform and the insertion groove can be interlocked and fixed after connection by extrusion. This allows the female roller head to transmit the power of the motor to the male roller head, so that the male roller head can drive the anilox roller to rotate together. When maintenance and cleaning are required, the anilox roller and the male roller head can be easily separated, making it easy to remove the anilox roller for cleaning. At the same time, it is also convenient to insert and install.

[0007] Preferably, the inner surface of the insertion joint is provided with a positioning groove, and the internal thread of the positioning groove is fitted with a first screw. The outer surface of the insertion joint is inserted and fixed with a motor, and the pin of the motor output end inside the insertion joint engages with the positioning groove. The outer surface of the first screw is in contact with the outer surface of the key at the motor output end.

[0008] By adopting the above technical solution, the roller head can be fixedly installed on the outer surface of the motor output end through the plug-in joint. The key at the motor output end can be engaged with the positioning groove to fix the motor when it rotates. The key can be fixed by the first screw, preventing the roller head from accidentally separating from the motor during rotation, reducing the probability of the roller head falling or slipping, and enabling the roller head to withstand higher rotational forces.

[0009] Preferably, a retaining ring is fixedly provided inside the roller head, and the diameter of the retaining ring is smaller than the diameter of the insertion point.

[0010] By adopting the above technical solution, the motor output end inserted into the female roller head can be limited by the retaining ring, so that the motor output end can be limited when it is inserted into the insertion point and will not pass through the female roller head.

[0011] Preferably, a guide positioning head is fixedly installed on the side surface of the male roller head near the female roller head, and the outer surface of the guide positioning head is arc-shaped, and the guide positioning head is inserted into the outer surface of the female roller head.

[0012] By adopting the above technical solution, the arc design of the guide positioning head allows the male roller head to be inserted into the female roller head, and then guided by the guide positioning head. This makes it easier for the hexagonal boss to be inserted into the insertion groove without alignment, thus reducing the difficulty of inserting the insertion groove and the hexagonal boss.

[0013] Preferably, the outer surface of the male roller head is provided with a roller shaft insertion interface, and the roller shaft insertion interface is threadedly connected to one end of the anilox roller.

[0014] By adopting the above technical solution, the roller male head can be installed and fixed on the outer surface of the anilox roller by screwing the roller shaft insertion interface into the anilox roller. At the same time, the hexagonal design of the roller male head allows it to be removed from one end of the anilox roller by turning the roller male head with a wrench, making it easy to replace the roller male head after it is damaged.

[0015] Preferably, the outer surface of the roller head near the insertion groove is provided with a fixed threaded opening, and a second screw is installed in the internal thread of the fixed threaded opening, and the outer surface of one end of the second screw is in contact with the outer surface of the guide positioning head.

[0016] By adopting the above technical solution, the second screw is screwed into the fixed threaded opening, so that the second screw can contact the outer surface of the guide positioning head, so that the male roller head can be fixed inside the female roller head, preventing the female roller head and the male roller head from shaking and wearing during the operation of the anilox roller.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the power transmission mechanism of the anilox roller:

[0018] 1. By inserting the inclined groove and the hexagonal concave-convex platform, the female roller head and the male roller head can be quickly connected. The rotation of the motor can drive the female roller head to rotate, so that the male roller head inserted with the female roller head can rotate together. The power transmission is realized by inserting the inclined groove and the hexagonal concave-convex platform. The wall pin drive or key drive is more secure and safer and more reliable. The female roller head and the male roller head can be quickly inserted and separated, which is convenient for disassembling and installing the anilox roller during regular cleaning. It is also safer and more reliable when transmitting power.

[0019] 2. The roller head can be inserted and fixed to the output end of the motor through the insertion joint, and the positioning groove can fix the key on the outer surface of the motor output end, so that the roller head can be locked and fixed to the output end of the motor through the positioning groove. Then, the key on the outer surface of the motor output end can be fixed by tightening the first screw, so that when the motor drives the roller head to rotate, the roller head can withstand greater force and reduce the chance of the roller head slipping.

[0020] 3. The male roller head can be fixedly installed on the outer surface of the anilox roller by rotating through the roller shaft insertion interface, which makes it easy to fix the male roller head on the outer surface of the anilox roller. When the male roller head wears out after a long period of insertion and removal, it can be removed from the anilox roller and replaced by using a wrench due to the hexagonal design of the male roller head, which makes it easy to install, remove and replace the male roller head.

[0021] 4. After the female roller head and the male roller head are inserted and fixed together, the second screw can be screwed into the fixed threaded opening so that the second screw can fit against the outer surface of the guide positioning head. This allows the male roller head to be fixedly installed inside the female roller head, preventing the female roller head and the male roller head from shaking and causing wear when they rotate, thus extending their service life.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] Please see Figure 1-6This utility model provides a technical solution: a power transmission mechanism for an anilox roller, including a female roller head 1, which is a barrel-shaped design, and an insertion point 3 is provided on one side surface of the female roller head 1. A male roller head 2 is inserted into the side surface of the female roller head 1 away from the insertion point 3, and the outer surface of the male roller head 2 is hexagonal. An insertion fastening structure is provided between the female roller head 1 and the male roller head 2. The insertion fastening structure enables the female roller head 1 and the male roller head 2 to be stably inserted, so that the female roller head 1 can transmit power to the male roller head 2.

[0031] The roller female head 1 can be fixedly inserted into the output end of the motor through the insertion joint 3. The insertion of the roller female head 1 and the roller male head 2 is safer and more reliable than pin drive, key rotation and coupling drive, so that the anilox roller can rotate more smoothly and safely.

[0032] The insertion fastening structure includes a hexagonal concave-convex platform 10. The end of the hexagonal concave-convex platform 10 near the female roller head 1 is provided with a chamfer. The end of the female roller head 1 near the male roller head 2 is provided with an insertion groove 7, and the insertion groove 7 is inserted into the hexagonal concave-convex platform 10. The hexagonal concave-convex platform 10 and the insertion groove 7 are designed to be inclined, and the outer surface of the insertion groove 7 is in close contact with the outer surface of the hexagonal concave-convex platform 10.

[0033] The chamfering of the hexagonal boss 10 makes it easier to insert the hexagonal boss 10 into the insertion groove 7. The inclined design of the insertion groove 7 and the hexagonal boss 10 makes the insertion smoother and easier, allowing the roller female head 1 and roller male head 2 to be firmly connected. When the anilox roller needs to be cleaned and maintained regularly, the roller female head 1 and roller male head 2 can be easily separated, making it convenient to remove the anilox roller for cleaning and maintenance.

[0034] The inner surface of the connector 3 is provided with a positioning groove 4, and the internal thread of the positioning groove 4 is fitted with a first screw 5. The outer surface of the connector 3 is connected and fixed with a motor, and the pin of the motor output end inside the connector 3 engages with the positioning groove 4. The outer surface of the first screw 5 is in contact with the outer surface of the key at the motor output end.

[0035] The roller head 1 can be inserted into the output end of the motor through the insertion joint 3, and the positioning groove 4 can limit the key set on the outer surface of the motor output end, and fix the key by screwing in the first screw 5. The positioning groove 4 and the key can increase the force that the roller head 1 bears when rotating and reduce the probability of the roller head 1 slipping when the motor rotates.

[0036] A retaining ring 6 is fixedly installed inside the roller head 1, and the diameter of the retaining ring 6 is smaller than the diameter of the insertion point 3.

[0037] The retaining ring 6 can limit the motor output end inserted into the female roller head 1, so that the female roller head 1 is not inserted too much, which would affect the insertion of the male roller head 2 into the female roller head 1.

[0038] A guide positioning head 9 is fixedly installed on the side surface of the male roller head 2 near the female roller head 1. The outer surface of the guide positioning head 9 is arc-shaped and is inserted into the outer surface of the female roller head 1.

[0039] The arc-shaped design of the guide positioning head 9 makes it easier to insert the male roller head 2 into the female roller head 1 without alignment, thus reducing the difficulty of connecting the male roller head 2 and the female roller head 1.

[0040] The outer surface of the male roller head 2 is provided with a roller shaft insertion interface 8, and the roller shaft insertion interface 8 is threadedly connected to one end of the anilox roller.

[0041] The male roller head 2 can be rotated and fixed on the outer surface of the anilox roller through the roller shaft insertion interface 8, which facilitates the installation and fixation of the male roller head 2. After the insertion interface of the male roller head 2 wears, the hexagonal design of the male roller head 2 makes it easy to remove the male roller head 2 from the anilox roller for replacement and installation.

[0042] The outer surface of the roller head 1 near the insertion groove 7 is provided with a fixed threaded opening 11, and a second screw 12 is installed in the internal thread of the fixed threaded opening 11, and the outer surface of one end of the second screw 12 is in contact with the outer surface of the guide positioning head 9.

[0043] When the second screw 12 is screwed into the fixing thread 11 and comes into contact with the outer surface of the guide positioning head 9, the male roller head 2 can be fixedly installed inside the female roller head 1, so that the female roller head 1 and the male roller head 2 will not wobble due to gaps or other reasons when the anilox roller rotates, reducing the probability of wear caused by the wobble of the female roller head 1 and the male roller head 2.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
