Description

Technical Field

[0001] This utility model belongs to the technical field of food packaging equipment, and in particular relates to an easily adjustable roll film vacuum bag filling machine. Background Technology

[0002] With increasing health awareness, the market demand for oatmeal, a nutritious and healthy food, continues to grow. However, oatmeal is highly susceptible to oxidation, moisture, and microbial contamination during storage and sales, leading to quality degradation and shortened shelf life. This project aims to conduct in-depth research on oatmeal packaging technology, especially focusing on vacuum packaging technology. By precisely controlling the vacuum level and extraction time, the project will explore the impact on the oxidative stability and physical properties of oatmeal, and develop a packaging solution that can effectively extend the shelf life of oatmeal and maintain its excellent quality. This will meet consumers' demand for high-quality oatmeal and promote the healthy development of the oatmeal industry.

[0003] Existing roll film vacuum bagging machines for food packaging are equipped with a storage bin for storing unsealed food packaging bags. The operator then takes out the stored food packaging bags from the storage bin, aligns the sealing position of the food packaging bags with the sealing position, and places them at the vacuum outlet of the roll film vacuum bagging machine. The electric heating sealing structure is then activated, and the food packaging bags are sealed by the electric heating structure while the vacuum is being drawn.

[0004] The aforementioned roll film vacuum bagging machine for food packaging only has a storage bin for temporary storage of food packaging bags. During operation, the operator still needs to manually remove the bags from the bin and hold them while vacuuming and sealing. This process not only places a heavy workload on the operator but also poses a certain degree of operational danger due to direct contact with the heating structure. Furthermore, the vacuum system uses a vacuuming method, which can easily suck food out of the packaging bags during the vacuuming process. This sucked-out food then enters the vacuum machine through the negative pressure vacuum tube, potentially damaging the machine. Therefore, we provide an adjustable roll film vacuum bagging machine to solve the aforementioned problems. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] Example 1

[0032] Please see Figure 1-5 This utility model is an easily adjustable roll film vacuum bag filling machine, including a frame 1, a base 2 and a feeding component 3. By using the feeding component 3, not only can food packaging bags that need to be vacuum sealed be pre-stored, but they can also be delivered one by one.

[0033] Specifically, a base 2 is installed at the bottom of the frame 1, and a feeding assembly 3 is installed at the upper rear of the frame 1. The feeding assembly 3 includes a mounting bracket 301 that is snapped onto the frame 1, and a feeding box 301 that is snapped onto the mounting bracket 301. An inclined discharge pipe 304 is embedded in the bottom of the left side wall of the feeding box 301. An arc-shaped plate 305c is provided on the outer side of one end of the discharge pipe 304 located inside the feeding box 301, and a feeding component 305 is installed inside the arc-shaped plate 305c.

[0034] Furthermore, a mounting groove 101 is provided at the upper rear of the frame 1, and the frame 1 is snapped into the mounting bracket 301 through the mounting groove 101.

The rotating shaft 305a rotates through the side wall of the feeding box 302 and connects to the motor shaft of the stepper motor.

[0035] The operation process of this embodiment is as follows: When in use, the food packaging bags to be packaged are neatly stacked and placed into the feeding box 302, and then the equipment is started. At this time, the rotating shaft 305a rotates with the linkage effect of the stepper motor, causing the feeding wheel 305b on its outer wall to rotate. Then, the food packaging bag located at the feeding trough 305d is gradually moved towards the discharge port 302b at its inner bottom under the crushing of the feeding wheel 305b, and flows into the interior of the discharge pipe 304 through the discharge port 302b.

[0036] Example 2

[0037] Please see Figure 6-7 Based on Example 1, a discharge component 4 is also provided. By using the vacuum component 404, the food packaging bag flowing into it can be vacuumed by squeezing air, and the bag opening can be sealed by the sealing component 403. The whole process does not require manual intervention, thus avoiding safety issues.

[0038] Specifically, the discharge assembly 4 includes a discharge box 401 embedded in the bottom of the material slide 102 on the frame 1. The bottom of the discharge box 401 is provided with a bottom groove 401b, and the bottom of the discharge box 401 is also rotatably connected to a discharge slide plate 402. The interior of the discharge box 401 is provided with a diamond-shaped groove 401a. A sealing element 403 is provided on one side of the groove 401a, and a vacuum element 404 is provided on the opposite side. A baffle plate 405 is provided on the inner wall of the bottom groove 401b where the sealing element 403 is located.

[0039] Furthermore, inner grooves 401c are provided on the top of both sides of the two grooves 401a, and rotating grooves 401d are provided on the outer walls of both sides of the discharge box 401. The top of the discharge slide plate 402 is rotatably connected in the rotating groove 401d. A sealing component 403 and a vacuum component 404 are respectively provided in the two inner grooves 401c. The inner grooves 401c are fixedly connected to the pneumatic rod 403b through the fixing bracket 403a. A push plate 403c is fixedly provided on the shaft end of the pneumatic rod 403b, and the outer wall of the push plate 403c is connected to the electric motor through the connecting column 403d. The hot plate 403e is fixedly connected, and the other inner groove 401c is fixedly connected to the pneumatic rod 404b through the second fixing bracket 404a. The second pneumatic rod 404b has a push plate 404c fixedly installed at the shaft end. The outer wall of the push plate 404c is equipped with an abutment plate 404e, and a blower pipe 404d is embedded in the abutment plate 404e. The bottom of the bottom groove 401b is rotatably connected to the plate shaft 405a, and the plate shaft 405a is rotatably connected to the discharge box 401 through the return spring 405b. At the same time, the plate shaft 405a is also inserted on the baffle plate 405.

[0040] The operation process of this embodiment is as follows: During use, the food packaging bag flowing out through the discharge pipe 304 enters the sliding trough 102 and flows into the interior of the discharge box 401. The food packaging bag slides down the inner wall of the second groove 401a of the discharge box 401 to the position of the baffle plate 405 and is blocked by the baffle plate 405. Then, the vacuum component 404 works, and the blowing pipe 404d on it blows out a high-speed airflow with the support of the air source pump on the production line. As the pneumatic rod 404b pushes, the blowing area of ​​the blowing pipe 404d gradually shrinks, thereby achieving the effect of squeezing out the air inside the food packaging bag until the food packaging bag is completely compressed and adhered to the inner wall of the second groove 401a. Then, the sealing component 403 works, which pushes the push plate 403c on its shaft end to extend through the pneumatic rod 403d. At this time, the opening of the food packaging bag is pushed out, bringing it closer to the air blower 404d. Then, the heating plate 403e works, generating heat and performing a heat-sealing effect on the part of the food packaging bag in contact with it. After sealing, the feeding component 305 in the feeding box 302 works again, delivering the food packaging bag into the discharging box 401. When the sliding food packaging bag reaches the position of the baffle plate 405, it generates a certain impact force on the sealed food packaging bag. This impact force causes the return spring 405b to rotate with the plate shaft 405a, thereby unloading the sealed food packaging bag. At the moment the sealed food packaging bag is unloaded, the baffle plate 405 loses the weight of the packaging bag, and the return spring 405b returns to its original position, thus blocking the unsealed food packaging bag again.
