Description

Technical Field

[0001] This utility model relates to the field of packaging bag production cutting, specifically a packaging bag production cutting device. Background Technology

[0002] Packaging bag cutting equipment is a crucial component of the packaging production line. Utilizing sophisticated mechanical structures and advanced control systems, it efficiently and accurately cuts raw materials or semi-finished packaging bags. This equipment can automatically convert continuous materials into individual packaging bags according to preset size and shape requirements, ensuring that each bag is the same size and has neat edges. Through automated operation, packaging bag cutting equipment not only improves production efficiency but also reduces manual intervention and lowers production costs, making it an indispensable tool in the modern packaging industry.

[0003] Small packaging bag production cutting equipment, as a semi-automated or highly flexible production tool, is widely used in the packaging industry due to its high flexibility, simple operation, high degree of automation and high precision. It can automatically execute the entire process from material feeding, precise positioning to precise cutting after the operation of the loading and unloading rollers is completed with manual assistance.

[0004] However, the aforementioned small-scale packaging bag production cutting equipment requires manual replacement of the material rollers. Tools such as wrenches are needed to disassemble the material rollers before moving them for replacement. The material rollers must be kept balanced and stable to prevent accidental collisions or falls. Then, the material rollers are reinstalled using a wrench. The process is cumbersome and inefficient. Therefore, it is necessary to modify the existing packaging bag production cutting equipment. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a packaging bag production cutting device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a packaging bag production cutting device, comprising a main body, an upper support rod and a lower support rod, a rotating groove being provided at the end of the lower support rod, a rotating rod being rotatably mounted on the inner wall of the rotating groove, a rotating cover plate being rotatably mounted at the end of the rotating rod, and a fixing groove being provided on the outer wall of the rotating rod, a limiting block being installed at the end of the upper support rod, and a fixing block corresponding to the fixing groove being slidably mounted on the outer wall of the limiting block, and a push block being slidably mounted on the inner wall of the fixing groove.

[0007] By adopting the above technical solution, the replacement of the rolling roller can be completed simply by rotating the rotating rod, which simplifies the replacement process, reduces cumbersome work steps, improves work efficiency, and ensures safety and stability during operation.

[0008] Furthermore, the outer wall of the main body of the equipment is equipped with two sets of upper support rods and lower support rods, and the outer wall of the rotating groove is designed at an angle.

[0009] By adopting the above technical solution, it is beneficial to stabilize the material roller, and the angled rotating groove restricts the rotation angle of the rotating rod.

[0010] Furthermore, a torsion spring is installed on the outer wall of the rotating cover plate, which serves to rotate the rotating cover plate to fit against the main body of the equipment.

[0011] By adopting the above technical solution, when the rotating rod is in a vertical state, the outer wall of the rotating cover plate is in close contact with the outer wall of the main body of the equipment, which helps to limit the position of the material roller and prevent it from moving randomly during operation.

[0012] Furthermore, two sets of fixing blocks are symmetrically installed on the outer wall of the limiting block, and the outer wall of the fixing blocks is designed at an angle.

[0013] By adopting the above technical solution, the angled design of the fixing block allows the rotating rod to be pushed into the limiting block when it rotates, which is beneficial for the rotating rod to smoothly enter the limiting block and be firmly limited in position by the two sets of fixing blocks.

[0014] Furthermore, the push block has a T-shaped design, with its end protruding from the outer wall of the rotating rod, and the width of the push block is equal to the width of the rotating rod.

[0015] By adopting the above technical solution, it is beneficial to push the pusher block to squeeze the two sets of fixed blocks, so that they enter the limiting block to release the limitation on the rotating rod, allowing the rotating rod to rotate freely.

[0016] Furthermore, a first spring is installed on the outer wall of the fixing block, and a second spring is installed on the outer wall of the push block.

[0017] By adopting the above technical solution, it is beneficial for the pusher block to be driven back to its original position by the second spring after completing the pushing task, and the first spring can squeeze the fixed block into the fixed groove to complete the limiting of the rotating rod.

[0018] Furthermore, the outer side of the rotating rod near the lower support rod is designed with an arc, and the inner side is designed with a right angle. After the rotating rod rotates, its height corresponds to that of the material roller.

[0019] By adopting the above technical solution, it is beneficial that when the rotating rod is rotating, the right-angled side of the rotating rod is in contact with the ground when it is in a vertical state, so that it can be stably maintained in a vertical state. Furthermore, the height of the rotating rod after rotation is conducive to the replacement of the rolling roller, simplifying the replacement process.

[0020] In summary, the present invention has the following main advantages:

[0021] This invention, by incorporating a limiting block, a rotating groove, a rotating rod, and a rotating cover plate, simplifies the replacement process by allowing the material roller to be rotated and replaced simply by rotating the rotating rod. This reduces cumbersome steps. The inclusion of a fixing groove, a fixing block, and a first spring ensures that after the rotating rod drives the material roller in a reverse reset motion, the fixing block automatically engages with the fixing groove under the force of the first spring, thus achieving a stable limiting position for the rotating rod. This ensures the material roller maintains a precise position under normal operating conditions, effectively preventing displacement caused by vibration or external forces. Finally, a push block and a second spring allow the rotating rod to be released from its limiting position by pushing the push block, enabling rotation for material roller replacement.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] A type of packaging bag production cutting equipment, such as Figure 1 - Figure 5As shown, the device includes a main body 1, an upper support rod 11, and a lower support rod 12. A rotating groove 14 is provided at the end of the lower support rod 12, and a rotating rod 2 is rotatably mounted on the inner wall of the rotating groove 14. The outer side of the rotating rod 2 near the lower support rod 12 is designed with an arc, while the inner side is designed with a right angle. This design facilitates the rotation of the rotating rod 2, ensuring that when the rotating rod 2 is in a vertical position, the right-angled side is in contact with the ground, thus maintaining its vertical position stably. A rotating cover plate 21 is rotatably mounted at the end of the rotating rod 2. When the rotating rod 2 is in a vertical position, the outer wall of the rotating cover plate 21 is flush with the main body of the device. The outer wall is tightly fitted, which helps to limit the position of the material roller and prevent it from moving randomly during operation. The outer wall of the rotating rod 2 is provided with a fixing groove 3. The end of the upper support rod 11 is equipped with a limiting block 13, and the outer wall of the limiting block 13 is slidably equipped with a fixing block 32 corresponding to the fixing groove 3. The two sets of fixing blocks 32 firmly limit the position of the rotating rod 2. The inner wall of the fixing groove 3 is slidably equipped with a push block 31. Pushing the push block 31 squeezes the two sets of fixing blocks 32, causing them to enter the limiting block 13 and release the limitation on the rotating rod 2, so that the rotating rod 2 can rotate freely.

[0031] Please see Figure 1 - Figure 4 The outer wall of the main body 1 of the equipment is equipped with two sets of upper support rods 11 and lower support rods 12, and the outer wall of the rotating groove 14 is designed at an angle, which is conducive to the stable support of the material roller, and the angled rotating groove 14 restricts the rotation angle of the rotating rod 2.

[0032] Please see Figure 1 - Figure 4 A torsion spring is installed on the outer wall of the rotating cover plate 21, which serves to rotate the rotating cover plate 21 to be in contact with the main body 1 of the equipment. When the rotating rod 2 is in a vertical state, the outer wall of the rotating cover plate 21 is in close contact with the outer wall of the main body 1 of the equipment, which helps to limit the position of the material roller and prevent it from moving randomly during operation.

[0033] Please see Figure 1 - Figure 5 Two sets of fixing blocks 32 are symmetrically installed on the outer wall of the limiting block 13, and the outer wall of the fixing block 32 is designed at an angle. The angled design of the fixing block 32 allows the rotating rod to be pushed into the limiting block 13 when it rotates, which is conducive to the rotating rod 2 being stably limited in position by the two sets of fixing blocks 32 after it smoothly enters the limiting block 13.

[0034] Please see Figure 1 - Figure 5 The push block 31 has a T-shaped design, and the end of the push block 31 protrudes from the outer wall of the rotating rod 2. The width of the push block 31 is equal to the width of the rotating rod 2. This makes it easier to push the push block 31 to squeeze the two sets of fixed blocks 32, so that they enter the limiting block 13 to release the limitation on the rotating rod 2, allowing the rotating rod 2 to rotate freely.

[0035] Please seeFigure 5 The outer wall of the fixed block 32 is equipped with a first spring 33, and the outer wall of the push block 31 is equipped with a second spring 34. This facilitates the push block 31 to be driven back to its original position by the second spring 34 after completing the pushing task. The first spring 33 can squeeze the fixed block 32 into the fixed groove 3 to complete the limiting of the rotating rod 2.

[0036] Please see Figure 1 - Figure 5 The outer side of the rotating rod 2 near the lower support rod 12 is designed with an arc, and the inner side is designed with a right angle. After the rotating rod 2 rotates, its height corresponds to that of the material roller. This is beneficial because when the rotating rod 2 is in a vertical state, the right angle side is in contact with the ground, which can make it stably maintain a vertical state. The height of the rotating rod 2 after rotation is also beneficial for the replacement of the rolling material roller, simplifying the replacement process.

[0037] The working principle of this utility model is as follows: When it is necessary to replace the material roller in the packaging bag production shearing equipment, the push block 31 is pushed first. The push block 31 squeezes the fixing block 32 and makes it enter the inner wall of the limiting block 13. At this time, the rotating rod 2 is unrestricted. After the push block 31 completes the pushing task, it is driven to reset by the second spring 34. Then the rotating rod 2 is rotated. The rotating cover plate 21 installed at the end of the rotating rod 2 is driven to rotate by the torsion spring. At this time, the material roller is unrestricted and is in a state that can be freely replaced. The rotating groove 14 opened at the end of the lower support rod 12 restricts the rotation angle of the rotating rod 2, ensuring the safety and controllability of the entire replacement process. After the worker completes the replacement by rolling the material roller, he lifts the rotating rod 2 to make it reset. When the rotating rod 2 rotates back to the limiting block 13, the rotating cover plate 21 is squeezed by the outer wall of the main body 1 and resets, firmly restricting the material roller in the designated position again. The fixing block 32 is squeezed into the fixing groove 3 by the first spring 33, completing the limitation of the rotating rod 2, improving the work efficiency, and also ensuring the safety and stability of the operation process.
