Description

Technical Field

[0001] This utility model relates to the field of vacuum packaging machine technology, specifically to a synchronous correction device for a continuous vacuum packaging machine. Background Technology

[0002] Vacuum packaging machines can automatically extract air from packaging bags and seal them after reaching a predetermined vacuum level. They can also be filled with nitrogen or other mixed gases before sealing. Vacuum packaging machines are commonly used in the food industry because vacuum packaging helps food resist oxidation and thus achieves long-term preservation.

[0003] A utility model with publication number CN216154119U discloses a food vacuum packaging machine with a correction mechanism, including a material conveying mechanism, a vacuuming mechanism, and a correction mechanism. The material conveying mechanism includes a conveyor belt, and the vacuuming mechanism is installed behind the correction mechanism. The correction mechanism includes correction swing arms installed on the left and right sides of the conveyor belt, with one end of each swing arm rotatably connected to a fixed column via a hinge. Push-pull rods are rotatably connected to the outer walls of both correction swing arms via hinges, and guide blocks are slidably connected to the push-pull rods. A return spring is sleeved on the push-pull rod inside the guide block. This correction mechanism, installed inside the vacuuming mechanism, corrects the deviation of the packaging bag before vacuum packaging, preventing positional shift of the packaging bag during conveying and affecting the vacuum packaging quality.

[0004] In implementing the above, the inventors discovered at least the following problems with this technology: the correction arm can only be adjusted by driving the cam, resulting in a limited range of motion. When dealing with some large or small food packages, it is impossible to adjust the correction arm to a suitable position, thus limiting the adaptability of the equipment. Therefore, we propose a synchronous correction device for a continuous vacuum packaging machine. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a synchronous correction device for a continuous vacuum packaging machine. This device solves the problem that the correction arm can only be adjusted by driving a cam, resulting in a small range of movement. When dealing with some large or small food packages, it is impossible to adjust the correction arm to the appropriate position, thus limiting the adaptability of the equipment.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a synchronous correction device for a continuous vacuum packaging machine, comprising a vacuum packaging machine and a conveyor belt device disposed at the inlet end of the vacuum packaging machine. Two adjustment boxes are symmetrically installed on the outer surface of the conveyor belt device. A motor is fixedly installed on the outer surface of the adjustment box. A threaded rod is fixedly installed through the output end of the motor through the adjustment box. One end of the threaded rod is rotatably connected to the inner wall of the adjustment box. A movable plate is threadedly connected to the outer surface of the threaded rod. A sliding rod is slidably connected inside the movable plate. Both sides of the sliding rod are fixedly connected to the inner wall of the adjustment box. A support rod is fixedly installed on one side of the movable plate. One end of the support rod penetrates into the inside of the conveyor belt device and is fixedly connected to a correction plate.

[0009] A dust collector is fixedly installed on one side of the regulating box, and an exhaust fan is fixedly installed on one side of the dust collector. The air inlet of the exhaust fan extends into the interior of the dust collector. A corrugated pipe is fixedly installed on one side of the dust collector. A dust collection groove is formed on the outer surface of the correction plate. One end of the corrugated pipe is fixedly installed inside the correction plate and communicates with the dust collection groove.

[0010] With the above technical solution, when faced with food packaging bags of different sizes, the operator can start the motor, which controls the movement of the moving plate. The moving plate can then drive the support rod and the correction plate to move, thereby adjusting the distance between the two correction plates. This allows the equipment to adapt to food packaging bags of different sizes, increasing the applicability of the equipment.

[0011] Preferably, sliders are fixedly installed on both sides of the movable plate, and the inner wall of the adjustment box is provided with a groove that matches the slider.

[0012] Through the above technical solution, the slider and the groove can limit the movement range of the moving plate, and at the same time make the moving plate move more smoothly.

[0013] Preferably, a first filter screen is fixedly installed at the air inlet end of the exhaust fan that extends into the dust collection box.

[0014] Through the above technical solution, the first filter screen can reduce the amount of dust inside the dust collection box entering the exhaust fan.

[0015] Preferably, a protective shell is fixedly installed on the outer surface of the regulating box, and the motor is disposed inside the protective shell.

[0016] The above technical solution can protect the motor and reduce the chance of external objects hitting the motor.

[0017] Preferably, a second filter screen is fixedly installed on the inner wall of the dust removal groove opened inside the correction plate.

[0018] Through the above technical solution, the second filter screen can reduce the entry of larger external objects into the dust removal tank inside the second filter screen.

[0019] Preferably, the outer surface of the correction plate has a concave cavity, and the inner wall of the concave cavity inside the correction plate is rotatably connected to a roller.

[0020] The above technical solution makes it easier to move food packaging bags.

[0021] Preferably, a collection frame is slidably connected inside the dust collection box.

[0022] The above technical solution allows staff to easily clean the dust inside the dust collection box.

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, the present invention provides a method with the following beneficial effects:

[0025] 1. When dealing with food packaging bags of different sizes, the operator can start the motor, which controls the movement of the moving plate. The moving plate can drive the support rod and the correction plate to move, thereby adjusting the distance between the two correction plates. This allows the equipment to adapt to food packaging bags of different sizes, increasing the applicability of the equipment.

[0026] 2. During the correction process, the staff can start the exhaust fan. The exhaust fan can draw some fine dust and impurities attached to the surface of the food packaging bag into the dust collection box through the dust collection groove and corrugated pipe on the correction plate, which facilitates the subsequent processing of the food packaging bag.
