Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of packaging mechanisms, and in particular to a packaging mechanism for food processing. Background Art
[0002] Traditional packaging mechanisms for food processing refer to mechanical equipment widely used in the early days in the field of food packaging, mainly realizing basic functions such as bagging, sealing, and conveying of food. Their core structures and working principles are relatively simple, relying more on mechanical transmission and manual intervention, and having a low degree of automation.
[0003] Traditional packaging mechanisms mostly rely on manual bag loading, bag holding, and position adjustment. Especially when dealing with packaging bags of different sizes, frequent manual adjustment is required for fixation. This leads to low overall packaging efficiency. At the same time, most of them are designed only for single-size packaging bags. When it is necessary to adjust the sealing position to adjust the size of the packaging bag, it is often necessary to disassemble and adjust components, which is time-consuming and laborious, greatly reducing the functionality of the packaging mechanism.
[0004] Therefore, in view of the problems that the above-mentioned packaging mechanism requires frequent manual adjustment for fixation when dealing with packaging bags of different sizes, and it is designed only for single-size packaging bags, and it often requires disassembling and adjusting components when it is necessary to adjust the sealing position to adjust the size of the packaging bag, a packaging mechanism for food processing can be designed. Summary of the Invention
[0005] In order to overcome the problems that the existing packaging mechanism requires frequent manual adjustment for fixation when dealing with packaging bags of different sizes, and also requires disassembling and adjusting components when it is necessary to adjust the sealing position to adjust the size of the packaging bag.
[0006] The technical solution is as follows: A packaging mechanism for food processing includes a packaging support frame; an inlet is installed at the upper end of the packaging support frame, a packaging bag feeding roller is installed at the side of the inlet at the upper end of the packaging support frame, a food bag inlet guide is installed at the side end of the packaging support frame, a bottom bag support component is installed near the lower end on the outside of the packaging support frame, a bag body clamping component is installed above the bottom bag support component, a control cavity is opened inside the packaging support frame, a lifting adjustment component is installed inside the control cavity, an anti-slip-off packaging component is installed at the side end of the lifting adjustment component, an inclined bag guide plate is fixedly connected to the lower end of the packaging support frame, a belt conveyor is installed below the inclined bag guide plate, and the bottom bag support component includes a first servo motor installed at one end on the outside of the packaging support frame, a transverse rotating rod is installed at the output end of the first servo motor, and a pressure-bearing support plate is welded and fixed to the outside of the transverse rotating rod.
[0007] Further, a storage groove for facilitating the adjustment of the pressure-bearing support plate is opened at the side end near the bottom of the packaging support frame, and a limiter is installed at the side end of the transverse rotating rod.
[0008] Furthermore, inside the bag body clamping assembly, there is a portal frame plate installed on the side end of the encapsulation support frame. A bidirectional air cylinder is installed on the inner wall of the portal frame plate, and two sets of moving plates are installed at the output end of the bidirectional air cylinder.
[0009] Furthermore, side clamping plates are fixedly connected to the side ends of the two sets of moving plates. Limiting sliders are fixedly connected to the side ends of the side clamping plates, and limiting sliding grooves that cooperate with the limiting sliders are opened on the outer surface of the encapsulation support frame.
[0010] Furthermore, a linear guiding rod is fixedly connected to the inner side of the portal frame plate, and the linear guiding rod passes through the two sets of side clamping plates and extends to the inner side wall of the portal frame plate. A buffer extrusion backing plate is installed on the inner side of the side clamping plates.
[0011] Furthermore, inside the lifting and adjusting assembly, there is an installation cross plate. A second servo motor is installed at the upper end of the installation cross plate. An adjusting lead screw is installed at the output end of the second servo motor, and a lead screw slider is threadedly connected to the outside of the adjusting lead screw.
[0012] Furthermore, a linkage plate is fixedly connected to the side end of the lead screw slider. A lifting chute is opened inside the encapsulation support frame, and a lifting block that slides in the lifting chute is fixedly connected to the side end of the linkage plate.
[0013] Furthermore, inside the anti-slip encapsulation assembly, there is a moving frame fixedly connected to the lifting block. Hydraulic telescopic rods are installed on both sides of the moving frame, and a lateral moving block is installed at the output end of the hydraulic telescopic rods.
[0014] Furthermore, an activity slot is penetrated and opened inside the moving frame. An activity pressing plate that slides inside the activity slot is fixedly connected to the side end of the lateral moving block. A telescopic air cylinder is installed on the side end of the moving frame, and sealing clamping plates are installed at the output end of the telescopic air cylinder and the side end of the activity pressing plate respectively. A heat sealing knife is installed at the upper end of the sealing clamping plate.
[0015] The beneficial effects are as follows: By driving the first servo motor in the present invention, the transverse rotating rod can drive the bearing support plate to rotate, so that the bearing support plate directly contacts the bottom of the packaging bag, providing a supporting force for the packaging bag. Its large contact area can evenly disperse the weights of the packaging bag and the food, preventing the bottom of the packaging bag from being damaged due to excessive local stress. During the encapsulation process, the bearing support plate can effectively offset the upward force generated on the packaging bag by operations such as heat sealing, keeping the position of the packaging bag stable, making the sealing more neat and tight, and improving the encapsulation quality. The bag body clamping component can quickly clamp and fix both sides of the packaging bag after the food falls into the packaging bag. By precisely controlling the magnitude of the clamping force, it can not only ensure that the packaging bag will not shift or loosen during the packaging process, but also will not damage the packaging bag due to excessive clamping force. This ensures that the packaging bag maintains a stable position and shape in subsequent processes such as sealing and conveying, providing a guarantee for achieving high-quality packaging and effectively reducing problems such as poor sealing and leakage caused by the shift of the packaging bag. The lifting and adjusting component can move the anti-slip packaging component to a suitable height and position according to the height of packaging bags of different specifications through precise adjustment. This flexibility in height enables the packaging mechanism to adapt to various packaging bags of different sizes, improving the versatility and applicability of the equipment, reducing the time and cost required for large-scale adjustment of the equipment due to changing the packaging bag specifications, and enhancing the adaptability of the equipment in different production scenarios. During the packaging process, the anti-slip packaging component prevents the packaging bag from sliding or shifting during the heat-sealing process through a fixed pressing method. At the same time, its efficient and precise packaging function can ensure that the packaging bag has a firm seal and good sealing performance, effectively preventing problems such as food leakage, moisture absorption, and oxidation, extending the shelf life of the food, ensuring the quality and safety of the food, and enhancing the market competitiveness of the product.

[0027] In the preparation stage, the encapsulation support frame 1 is stably placed in the working area, the power supply is connected and each component is debugged to the initial state. The packaging bag roll material is installed on the packaging bag feeding roller 3 and adjusted to the appropriate position. Manually pull the front end of the packaging bag to the food bagging guiding port 4 to prepare for loading. In the bagging stage, the food enters the feeding port 2, and then enters the packaging bag under the guidance of the food bagging guiding port 4.
