Description

Technical Field

[0001] This utility model relates to the field of adjustment devices, specifically a front universal transmission adjustment device for a packaging laminating machine. Background Technology

[0002] The front universal transmission adjustment device of the packaging laminating machine is a key component in the front conveying system of the equipment, which is used to realize power transmission and flexibly adjust the conveying parameters. Its core function is to ensure that the material to be laminated can be conveyed smoothly, accurately and without deviation before entering the laminating stage, while adapting to the dynamic changes in the material conveying process.

[0003] The existing machines are not securely fixed, which makes the devices prone to shifting during operation. The height adjustment operation is complicated, the movement is unstable during the adjustment process, and there are problems with angle transmission or power transmission. Utility Model Content

[0004] The purpose of this utility model is to provide a front conveyor universal transmission adjustment device for a packaging and laminating machine, which has the advantages of adjusting the front conveyor height and being tightly and securely integrated with the machine, thus solving the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The front feed universal transmission adjustment device of the packaging laminating machine includes a base. Two first slots are opened through the upper end of the base. Limiting posts are fixed to the inner walls of the two first slots. A first connecting plate is fixed to the lower end of the side walls of the two limiting posts. A first triangular plate is fixed to the upper end of the first connecting plate. A moving mechanism is provided on the inner wall of the first connecting plate. A second connecting plate is fixed to the upper end of the side walls of the two limiting posts. A second triangular plate is fixed to the lower end of the second connecting plate. A support block is fixed to the upper end of the moving mechanism. A rotating mechanism is fixed to the upper end of the support block.

[0007] Preferably, the moving mechanism includes a first connecting plate, a second triangular plate, and a first threaded hole extending through the upper end of a support block. A threaded rod is threaded onto the inner wall of the first threaded hole. A connecting block is slidably mounted on the side walls of the two limiting posts. A second slot is extending through the lower end of the connecting block. A first rotating post is fixedly connected to the upper end of the threaded rod. The side wall of the first rotating post is slidably mounted on the inner wall of the second slot. One end of a universal joint is rotatably mounted on the upper end of the first rotating post.

[0008] It is worth noting that when the universal joint rotates, it can drive the threaded rod to rotate, and when the threaded rod rotates, the second connecting plate moves vertically.

[0009] Preferably, the rotating mechanism includes a protective shell fixed to the upper end of a support block, a fixing block fixed to one side of the protective shell, a third slot hole through one side of the fixing block, one end of a second rotating column rotatably mounted on the other end of a universal joint, the side wall of the second rotating column rotatably mounted on the inner wall of the third slot hole, and a handwheel fixed to the other end of the second rotating column.

[0010] It is worth noting that when the handwheel is turned, it drives the universal joint to rotate via the second rotating column.

[0011] Preferably, the universal joint is located on the inner wall of the protective shell.

[0012] It is worth noting that the protective shell protects the universal joint from damage.

[0013] Preferably, the first triangular plate is located at the lower end of the machine, and the second triangular plate is located at the upper end of the machine.

[0014] It is worth noting that the height of the machine's front feed triangle is adjusted using the first and second triangles.

[0015] Preferably, when the threaded rod rotates, the second connecting plate moves vertically along the two limiting posts.

[0016] It is worth noting that the height of the second triangle is controlled by the vertical movement of the second connecting plate.

[0017] Preferably, a fixing frame is provided at the lower end of the base.

[0018] It is worth noting that the mounting bracket and the mounting bracket at the bottom of the machine are flush, which makes it easy to fix the device.

[0019] Preferably, one side of the base is provided with a bolt for connection to the machine's hook.

[0020] It is worth noting that the device and the machine are connected together.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] This utility model effectively prevents deviation during use and improves overall stability through a double fixing structure consisting of a lower fixing bracket and a hook connected by bolts. The structure, combining handwheel drive, threaded rod transmission, and double limit post guidance, enables stable and controllable vertical movement of the second connecting plate and the second triangular plate. Operation is convenient and adjustment is precise. The limit posts ensure stable movement direction and prevent wobbling. The design of connecting the first and second rotating columns with a universal joint solves the problem of stable power transmission at different angles, ensuring that the rotation of the handwheel can be efficiently converted into the drive of the threaded rod, thus improving the adaptability and reliability of the universal transmission.
