Description

Technical Field

[0001] The utility model relates to the technical field of packaging machine drums, and specifically relates to a drum length adjusting mechanism for a food packaging machine. Background Art

[0002] In the modern food processing and packaging industry, automated packaging machines have become one of the key equipment for improving production efficiency and ensuring food hygiene and safety. Among them, the drum, as the core conveying component in the packaging machine, undertakes the important task of transporting food from one end to the other for packaging processing. However, the traditional design of packaging machine drums often has some limitations and deficiencies.

[0003] Many packaging machine drums on the existing market generally adopt a fixed-size design and cannot be flexibly adjusted according to the sizes and requirements of different products. During the equipment installation and debugging process, it is often difficult for the fixed-size drum to perfectly match the layout requirements of various production lines. Installers have to adapt the position and length of the drum by modifying the bracket additionally, which increases the installation difficulty and time cost. Content of the Utility Model

[0004] (I) Purpose of the Utility Model

[0005] In view of this, the purpose of the present utility model is to provide a drum length adjusting mechanism for a food packaging machine, which solves the problems raised in the above background.

[0006] (II) Technical Solution

[0007] A drum length adjusting mechanism for a food packaging machine includes a drum main body. Connecting shafts are arranged on both sides of the drum main body, and a gear plate is installed on the outer surface of one of the connecting shafts. A cavity is formed in the inner wall of the drum main body, and an adjusting rod is movably installed in the cavity. One side of the adjusting rod is connected to a connecting shaft. A clamping ring is fixedly installed on one side of the drum main body, and threads are formed on the outer surface of the clamping ring. A plurality of vertical through grooves are formed on the outer surface of the clamping ring, and a rotating ring is movably installed on the outer surface of the clamping ring.

[0008] Preferably, the outer surface of the adjusting rod is serrated. The serrated design increases the friction between the adjusting rod and the clamping ring, helps to maintain the stability of the adjusting rod during the clamping process, and prevents it from accidentally sliding due to external forces.

[0009] Preferably, two limiting grooves are formed in the inner wall of the cavity of the drum main body, and limiting blocks are movably installed in the two limiting grooves. The limiting blocks are fixedly connected to one end of the adjusting rod. The cooperation between the limiting grooves and the limiting blocks restricts the movement track of the adjusting rod in the cavity, prevents it from shifting or shaking during the adjustment process, and enhances the overall stability of the drum.

[0010] Preferably, the top end of the limit block is arc-shaped. The arc-shaped design makes the contact between the limit block and the inner wall of the drum body smoother during movement, reducing the resistance and friction during movement and improving the smoothness of adjustment.

[0011] Preferably, one end of the rotating ring is conical. The conical design enables the rotating ring to gradually reduce the extrusion force on the clamping ring during rotation, facilitating the user to easily control the detachment and clamping of the rotating ring by rotating the operating rod and improving the convenience of operation.

[0012] Preferably, limit plates are fixedly installed on both sides of the drum body. The limit plates play a role in transporting items, ensuring that the items move on the outer surface of the drum body.

[0013] Preferably, multiple groups of operating rods are fixedly installed on the outer surface of the rotating ring, and rubber is wrapped around the outer surfaces of the multiple groups of operating rods. The operating rods wrapped with rubber provide a better grip and anti-slip performance, making the user more comfortable and stable during the operation process.

[0014] From the above technical solutions, it can be seen that the present application has the following beneficial effects:

[0015] 1. Through the flexible movement of the adjusting rod within the drum body, this mechanism can adjust the length of the drum in real time and quickly to adapt to different installation size requirements. This flexibility greatly improves the adaptability and application range of the packaging machine.

[0016] 2. Through the flexible movement of the adjusting rod within the drum body, this mechanism can adjust the length of the drum in real time and quickly to adapt to the food packaging requirements of different sizes and shapes. This flexibility greatly improves the adaptability and application range of the packaging machine. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Please refer to Figures 1-5 , an embodiment provided by the present utility model:

[0025] A drum length adjusting mechanism for a food packaging machine, including a drum body 1. Connecting shafts 3 are arranged on both sides of the drum body 1, and a gear plate 4 is installed on the outer surface of one connecting shaft 3. A cavity is opened in the inner wall of the drum body 1, and an adjusting rod 5 is movably installed in the cavity. One side of the adjusting rod 5 is connected to the connecting shaft 3. A clamping ring 8 is fixedly installed on one side of the drum body 1, and threads are provided on the outer surface of the clamping ring 8. A plurality of groups of vertical through grooves 811 are opened on the outer surface of the clamping ring 8, and a rotating ring 6 is movably installed on the outer surface of the clamping ring 8.

[0026] Furthermore, the outer surface of the adjusting rod 5 is serrated. The serrated design increases the friction between the adjusting rod 5 and the clamping ring 8, which helps to maintain the stability of the adjusting rod 5 during the clamping process and prevents it from accidentally sliding due to external forces.

[0027] Furthermore, two groups of limiting grooves 9 are opened on the inner wall of the cavity of the drum body 1, and limiting blocks 511 are movably installed in the two groups of limiting grooves 9. The limiting blocks 511 are fixedly connected to one end of the adjusting rod 5. The cooperation between the limiting grooves 9 and the limiting blocks 511 restricts the movement trajectory of the adjusting rod 5 in the cavity, prevents it from shifting or shaking during the adjustment process, and enhances the overall stability of the drum.

[0028] Furthermore, the top end of the limiting block 511 is arc-shaped. The arc-shaped design makes the contact between the limiting block 511 and the inner wall of the drum body 1 smoother during movement, reduces the resistance and friction during movement, and improves the smoothness of adjustment.

[0029] Furthermore, one end of the rotating ring 6 is conical. This conical design enables the rotating ring 6 to gradually reduce the extrusion force on the clamping ring 8 during rotation, facilitating the user to easily control the detachment and clamping of the rotating ring 6 by rotating the operating rod 7, thus improving the convenience of operation.

[0030] Furthermore, limiting plates 2 are fixedly installed on both sides of the drum main body 1. The limiting plates 2 play a role in transporting items, ensuring that the items move on the outer surface of the drum main body 1.

[0031] Furthermore, multiple groups of operating rods 7 are fixedly installed on the outer surface of the rotating ring 6, and rubber is wrapped around the outer surfaces of the multiple groups of operating rods 7. The rubber-wrapped operating rods 7 provide a better grip and anti-slip performance, making the user more comfortable and stable during the operation process.

[0032] Working principle: The drum main body 1 is firmly connected to the mounting bracket through the connecting shafts 3 on both sides. The gear plate 4 installed on the outer surface of one of the connecting shafts 3 is used to connect with components such as a transmission chain to achieve the rotational movement of the drum. An adjusting rod 5 is preset in the inner wall cavity of the drum main body 1. One end of the adjusting rod 5 is matched with the limiting groove 9 through the limiting block 511 to ensure the stability and guiding property of the adjusting rod 5 during movement. When the length of the drum needs to be adjusted, first rotate the rotating ring 6 through the operating rod 7. One end of the rotating ring 6 is designed to be conical, facilitating the gradual reduction of the extrusion force on the clamping ring 8 during rotation. The threaded design and multiple groups of vertical through grooves 811 on the outer surface of the clamping ring 8 enable the rotating ring 6 to move along the threaded direction during rotation and gradually detach from the clamping ring 8. During this process, the clamping force of the clamping ring 8 on the adjusting rod 5 gradually weakens, preparing for the movement of the adjusting rod 5. With the complete detachment of the rotating ring 6, the adjusting rod 5 loses the clamping and fixing force. At this time, the adjusting rod 5 can be manually pushed to move in the inner wall cavity of the drum main body 1. When the adjusting rod 5 moves to the desired position, rotate the rotating ring 6 again to make it move along the threaded direction and re-clamp the adjusting rod 5. At this time, the clamping ring 8 is tightly matched with the rotating ring 6 through the threaded design and multiple groups of vertical through grooves 811 on its outer surface to achieve the firm fixation of the adjusting rod 5, thereby locking the new length of the drum.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
