Description

Technical Field

[0001] This application relates to the field of printing technology, specifically to a detachable printing roller for a label printing machine. Background Technology

[0002] Traditional label printing machines mostly use a fixed printing roller design. Although this design is simple in structure and low in cost, it has many inconveniences in actual production. For example, when it is necessary to change to different sizes of label paper or adjust printing parameters, the traditional printing roller cannot quickly adapt to the new production requirements, resulting in low production efficiency. In addition, the fixed printing roller is prone to wear after long-term use, and maintenance and replacement are more difficult, increasing maintenance costs and downtime.

[0003] Traditional label printing machines mostly use a fixed printing roller design, which fixes the printing roller to the printing machine frame with bolts or other fasteners. It has the advantages of simple structure and low cost. However, its biggest drawback is that it is inconvenient to replace and maintain. Once the printing roller is damaged or needs to be replaced, the entire printing roller assembly must be removed, which is time-consuming and laborious. Moreover, it is prone to wear after long-term use, which increases maintenance costs and downtime. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a detachable printing roller for a label printing machine, which has advantages such as easy replacement and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a detachable printing roller for a label printing machine, comprising a frame, two insert frames at the top of the frame, connecting blocks slidably inserted into the interior of each insert frame, arrow-shaped bottom ends of each connecting block, slots on one side of each connecting block, and shaft seats fixedly connected to the top ends of each connecting block. A printing shaft is rotatably connected between the two shaft seats via a bearing, and a printing roller is fixedly connected to the outer surface of the printing shaft.

[0006] Limiting frames are fixedly connected to both the left and right sides of the frame. Each of the two limiting frames has a threaded hole on one side. A limiting rod is slidably inserted into the inside of each threaded hole. Each of the two limiting rods has a retaining ball at one end that is close to the other. Each retaining ball is located inside the retaining groove that is close to it.

[0007] With the above solution, the frame serves as the supporting structure for the entire printing roller assembly. Its top is designed with two insert frames, and the bottom of the connecting block is designed in an arrow shape to facilitate the squeezing of the limiting rod and smooth entry when inserting the insert frames. The side of the connecting block is provided with a slot for cooperating with the ball to achieve a stable connection, thereby enabling the rapid replacement of the printing roller. This not only reduces maintenance costs but also reduces downtime, ensuring the continuity and stability of production.

[0008] Furthermore, each of the two limiting rods has a handle fixedly connected to one end that is far from the other.

[0009] The above solution, with the handle, allows users to easily pull the limit lever to release the ball from its position on the connecting block.

[0010] Furthermore, springs are fixedly connected between each of the two handles and the adjacent limiting bracket.

[0011] The above solution, through the setting of the spring, can realize the automatic reset of the limiting ball. Thus, after the connecting block is inserted into the insert frame, its arrow-shaped end squeezes the limiting ball, causing the limiting rod to move to one side. Through the reset of the spring, the limiting ball can automatically enter the slot, thereby achieving the purpose of quick connection.

[0012] Furthermore, both of the limiting rods have threaded grooves at the ends near the ball.

[0013] With the above solution and settings, after pulling the handle, the limit rod can be threadedly connected to the limit frame by rotating the handle, thereby preventing the spring from driving the limit rod to reset and making it easier for the user to disassemble the connecting block.

[0014] Furthermore, handles are fixedly connected to the top of the two connecting blocks on their opposite sides.

[0015] The above solution, with the addition of a handle, makes it easy for users to pull the connecting block out of the insert frame.

[0016] Furthermore, each of the ball-holding devices is threaded to one end of its adjacent limiting rod.

[0017] The above solution and settings make it easy for users to replace the retaining ball, preventing the connecting block from wobbling up and down after the retaining ball wears down.

[0018] Furthermore, the outer surface of each ball and the bottom of the connecting block are polished.

[0019] The above solution and settings can reduce the coefficient of friction when the two parts come into contact, thereby improving the smoothness of the connection.

[0020] Furthermore, both handles are slidably connected to their adjacent insert frames.

[0021] The above scheme and settings can guide the back-end travel after the connecting block is inserted into the frame.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This is a detachable printing roller for a label printing machine. The frame serves as the support structure for the entire printing roller assembly. The top of the frame has two insert frames, and the bottom of the connecting block is designed in an arrow shape to facilitate the squeezing of the limiting rod and smooth insertion when inserting the insert frames. The side of the connecting block has a slot for cooperating with the ball to achieve a stable connection, thereby enabling quick replacement of the printing roller. This not only reduces maintenance costs but also reduces downtime, ensuring the continuity and stability of production. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of a detachable printing roller for a label printing machine includes a frame 1. The top of the frame 1 is provided with two insert frames 2. A connecting block 3 is slidably inserted into the interior of each insert frame 2. The bottom of each connecting block 3 is arrow-shaped. A slot 5 is provided on one side of each connecting block 3. A bearing seat 6 is fixedly connected to the top of each connecting block 3. A printing shaft 7 is rotatably connected between the two bearing seats 6 via a bearing. A printing roller 8 is fixedly connected to the outer surface of the printing shaft 7. A handle 16 is fixedly connected to the top of the side of each connecting block 3 that is far apart from each other. The handle 16 makes it easy for the user to pull the connecting block 3 out of the insert frame 2.

[0032] Please see Figure 1 , Figure 2 and Figure 3 Limiting frames 9 are fixedly connected to both the left and right sides of the frame 1. Each of the two limiting frames 9 has a threaded hole 10 on one side. A limiting rod 11 is slidably inserted into the inside of each threaded hole 10. Each of the two limiting rods 11 has a retaining ball 12 at one end close to the other. Each retaining ball 12 is located inside the retaining groove 5 close to it. By setting the retaining ball 12, the up and down movement of the connecting block 3 can be limited to ensure the stability of the connection.

[0033] Please see Figure 1 , Figure 2 and Figure 3 Each of the two limiting rods 11 has a handle 13 fixedly connected to one end of each other. The handle 13 allows the user to pull the limiting rod 11 to release the ball 12 from limiting the connecting block 3. A spring 14 is fixedly connected between each of the two handles 13 and the adjacent limiting frame 9. The spring 14 enables the limiting ball to automatically reset. After the connecting block 3 is inserted into the insert frame 2, its arrow-shaped end squeezes the limiting ball, causing the limiting rod 11 to move to one side. The reset of the spring 14 enables the limiting ball to automatically enter the slot 5, thus achieving the purpose of quick connection.

[0034] Please see Figure 1 , Figure 2 and Figure 3 Both limiting rods 11 have threaded grooves 15 at the ends near the locking balls 12. With this setting, after pulling the handle 13, the limiting rods 11 can be threadedly connected to the limiting frame 9 by rotating the handle 13, thereby preventing the spring 14 from driving the limiting rods 11 to reset, which facilitates the user's disassembly of the connecting block 3. Each locking ball 12 is threadedly connected to one end of its adjacent limiting rod 11. With this setting, the user can easily replace the locking balls 12 and avoid the connecting block 3 from shaking up and down after the locking balls 12 are worn. The outer surface of each locking ball 12 and the bottom end of the connecting block 3 are polished. With this setting, the coefficient of friction when the two are in contact can be reduced, thereby improving the smoothness of connection. Both handles 16 are slidably connected to their adjacent insertion frames 2. With this setting, the rear end stroke of the connecting block 3 after it is inserted into the insertion frame 2 can be guided.

[0035] In this embodiment, a detachable printing roller 8 for a label printing machine is provided. The frame 1 serves as the support structure for the entire printing roller 8 assembly. The top of the frame 1 is designed with two insert frames 2. The bottom of the connecting block 3 is designed in an arrow shape to facilitate the squeezing of the limiting rod 11 and smooth entry when the insert frame 2 is inserted. The side of the connecting block 3 is provided with a slot 5 for cooperating with the ball 12 to achieve a stable connection, thereby enabling the rapid replacement of the printing roller 8. This not only reduces maintenance costs but also reduces downtime, ensuring the continuity and stability of production.

[0036] The working principle of the above embodiment is as follows: First, the frame 1, as the supporting structure of the entire printing roller 8 assembly, is stably installed in the corresponding position of the label printing machine. The top of the frame 1 is designed with two insert frames 2, which provide space for the insertion of the connecting block 3. When the printing roller 8 needs to be installed, the operator first holds the handle 16 at the top of the connecting block 3 and aligns the arrow-shaped end of the bottom of the connecting block 3 with the entrance of the insert frame 2. Due to the arrow-shaped design, the connecting block 3 can easily squeeze the limiting rod 11 during insertion, causing the limiting rod 11 to move to one side. As the connecting block 3 goes deeper, the slot 5 on its side gradually approaches the ball 12 at one end of the limiting rod 11. At this time, the spring 14 returns to its original position. The positioning function begins to appear, pushing the limiting rod 11 and the locking ball 12 towards the locking groove 5. When the locking ball 12 is fully inside the locking groove 5, the connecting block 3 is stably fixed in the insert frame 2, realizing the installation of the printing roller 8. When the printing roller 8 needs to be replaced, the operator only needs to hold the handle 13 and gently pull the limiting rod 11 to make the locking ball 12 exit from the locking groove 5 and make its threaded groove 15 threadedly connected to the threaded hole 10. At this time, the connecting block 3 loses its limiting function, and the operator can hold the handle 16 to pull the connecting block 3 out of the insert frame 2. In addition, the design of the threaded connection between the locking ball 12 and the limiting rod 11 makes it easy to replace the locking ball 12 after wear, avoiding the up and down shaking of the connecting block 3.
