Description

Technical Field

[0001] The utility model relates to the technical field of vacuum packaging, in particular to a vacuum packaging machine for evacuation. Background Art

[0002] In the food industry, for the convenience of storage and transportation of foods (such as rice, flour, etc.) after production, vacuum packaging is usually required. Vacuum packaging means removing the air inside the packaging bag and sealing it to isolate the food inside the packaging bag from the outside world. In a vacuum state, the growth of aerobic microorganisms slows down or is inhibited, reducing the degradation of proteins and the oxidative rancidity of fats. In addition, through vacuum packaging, lactic acid bacteria and anaerobic bacteria multiply, and the pH is reduced to 5.6 - 5.8, further inhibiting the growth of other bacteria, thus extending the storage period of the product. When vacuum packaging a rice bag, during the process of flattening the bag in both directions by a push plate, due to the large gravity of the rice grains, it is difficult for the rice grains at the lower part of the rice bag to transfer to the upper part. As a result, after the rice bag is vacuum-sealed, the thickness is uneven, affecting subsequent stacking and transportation. In view of the existing problems, a vacuum packaging machine for evacuation is proposed. Content of the Utility Model

[0003] The purpose of the utility model is to solve the drawback that during the process of flattening a rice bag in both directions by a push plate in the prior art, due to the large gravity of the rice grains, it is difficult for the rice grains at the lower part of the rice bag to transfer to the upper part, and a vacuum packaging machine for evacuation is proposed.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A vacuum packaging machine for evacuation is designed, including a vacuum sealing mechanism, a shaping and flattening mechanism, and a mounting frame. The vacuum sealing mechanism is installed above the mounting frame, and the shaping and flattening mechanism is installed below the mounting frame. The shaping and flattening mechanism includes a pushing mechanism and an auxiliary flat-pushing assembly. The pushing mechanism is installed at the lower part of the mounting frame, and a first fixing frame is installed on the bottom surface of the mounting frame. Push plates are respectively installed on the pushing mechanism and the first fixing frame.

[0006] The auxiliary flat-pushing assembly is installed on the push plate. The auxiliary flat-pushing assembly includes a second fixing frame and a transmission belt. The second fixing frame is in a U-shaped plate structure. A hanging frame is fixedly installed at the upper end of the second fixing frame, and the hanging frame is hung on the upper end of the push plate. The transmission belt is rotatably sleeved outside both sides of the second fixing frame and the push plate, and upper push plates are horizontally fixedly installed on the transmission belts on both sides of the push plate.

[0007] Preferably, driving motors are fixedly installed on the back parts of both sides of the second fixing frame. A driving wheel is fixedly installed on the output shaft of the driving motor. The other end of the driving wheel is rotatably installed with a rotating seat, and the rotating seat is fixedly installed on the second fixing frame. The transmission belt is rotatably sleeved on the driving wheel.

[0008] Preferably, belt grooves are formed in the second fixing frame on both sides corresponding to the transmission belt. Limiting strips are fixedly installed in an array at the outer ends of the belt grooves. The transmission belt is located in the belt grooves. A limiting frame is fixedly installed at the upper end of the hanging frame, and the transmission belt movably penetrates through the limiting frame.

[0009] Preferably, tension wheels are fixedly installed at both the upper and lower ends of the belt groove, and the transmission belt is slidably sleeved on the tension wheels.

[0010] Preferably, bottom shafts are symmetrically installed on both sides at the lower end of the second fixing frame, and the transmission belt is rotatably sleeved on the bottom shafts.

[0011] Preferably, a rotating groove is formed in the upper pushing plate, and a roller is rotatably installed in the rotating groove.

[0012] The vacuum packaging machine proposed by the present utility model has the beneficial effects as follows:

[0013] 1. When an unsealed bag with a specification of 20 - 50 KG is placed into the packaging machine, the shaping and flattening mechanism starts to work. One push plate is pushed gradually closer to the other push plate through the pushing mechanism until the unsealed bag is flattened. At this time, when the transmission belts on both sides of the push plate rotate synchronously, it can drive the upper pushing plate to move horizontally upward, so as to overcome the material accumulation at the lower part caused by the gravity of the filling material in the unsealed bag. At this time, when the two push plates finally clamp the unsealed bag, the thickness of the material in the final vacuum packaging bag can be relatively consistent, which is also convenient for subsequent transportation and stacking.

[0014] 2. The driving motor drives the driving wheel to rotate slowly, and the driving wheel is in transmission connection with the transmission belt, so that the transmission belts on both sides can be driven to rotate synchronously, effectively saving manpower and material resources. At the same time, the belt groove and the limiting frame are used to limit the transmission belt to prevent it from slipping during the rotation process. The setting of the tension wheel and the bottom shaft makes the transmission belt always in a taut state, reducing the slippage during the rotation of the transmission belt and facilitating the horizontal lifting of the upper pushing plate.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Embodiment 1

[0024] Referring to Figure 1-6 , the vacuum packaging machine includes a vacuum pumping and sealing mechanism 1, a shaping and flattening mechanism 2, and a mounting frame 3. The vacuum pumping and sealing mechanism 1 is installed above the mounting frame 3. The vacuum pumping and sealing mechanism 1 can automatically flatten the unsealed package. After the vacuum pumping is completed, the air extraction port rises and the sealing starts to heat seal to complete the sealing. The shaping and flattening mechanism 2 is installed below the mounting frame 3. The vacuum pumping and sealing mechanism 1 and the shaping and flattening mechanism 2 are arranged correspondingly. The shaping and flattening mechanism 2 includes a pushing mechanism 21 and an auxiliary flat-pushing assembly 24. The pushing mechanism 21 is installed at the lower part of the mounting frame 3. A first fixing frame 23 is installed on the bottom surface of the mounting frame 3. Push plates 22 are respectively installed on the pushing mechanism 21 and the first fixing frame 23. When an unsealed package with a specification of 20 - 50 KG is placed in the packaging machine, that is, the shaping and flattening mechanism 2 starts to work. By the pushing mechanism 21, one of the push plates 22 is gradually pushed closer to the other push plate 22 until the unsealed package is flattened.

[0025] The auxiliary horizontal pushing component 24 is installed on the pushing plate 22. The auxiliary horizontal pushing component 24 includes a second fixing frame 241 and a transmission belt 242. The second fixing frame 241 is in a U-shaped plate structure. A hanging frame 245 is fixedly installed at the upper end of the second fixing frame 241. The hanging frame 245 is hung on the upper end of the pushing plate 22. The transmission belt 242 is rotatably sleeved outside both sides of the second fixing frame 241 and the pushing plate 22. Upper pushing plates 244 are horizontally and fixedly installed on the transmission belts 242 on both sides of the pushing plate 22. At this time, by synchronously rotating the transmission belts 242 on both sides of the pushing plate 22, the upper pushing plates 244 can be driven to move horizontally upward, so that it can overcome the material accumulation at the lower part caused by the gravity of the filling material in the unsealed bag. At this time, when the two pushing plates 22 finally clamp the unsealed bag, the thickness of the material in the final vacuum packaging bag can be made relatively consistent, which is also convenient for subsequent transportation and stacking.

[0026] Embodiment 2

[0027] According to Embodiment 1, it is difficult to control the rotation and tension of the transmission belt 242 in Embodiment 1, resulting in difficulty in ensuring the horizontal rise of the upper pushing plate 244. Referring to Figure 1-6 , as another preferred embodiment of the present invention, on the basis of Embodiment 1;

[0028] Driving motors 243 are respectively fixedly installed on the back parts of both sides of the second fixing frame 241. A driving wheel 246 is fixedly installed on the output shaft of the driving motor 243. The other end of the driving wheel 246 is rotatably installed with a rotating seat 2461. The rotating seat 2461 is fixedly installed on the second fixing frame 241. The transmission belt 242 is rotatably sleeved on the driving wheel 246. By driving the driving wheel 246 to rotate slowly through the driving motor 243, and the driving wheel 246 is in transmission connection with the transmission belt 242, the transmission belts 242 on both sides can be driven to rotate synchronously, effectively saving manpower and material resources.

[0029] Belt grooves 2411 are respectively formed on both sides of the second fixing frame 241 corresponding to the transmission belts 242. Limit strips 2412 are fixedly installed in an array at the outer ends of the belt grooves 2411. The transmission belt 242 is located in the belt grooves 2411. A limit frame 2451 is fixedly installed at the upper end of the hanging frame 245. The transmission belt 242 movably penetrates through the limit frame 2451. At the same time, the transmission belt 242 is limited by the belt grooves 2411 and the limit frame 2451 to prevent it from slipping during rotation.

[0030] Tension wheels 247 are fixedly installed at both the upper and lower ends of the grooved part 2411. The drive belts 242 are all slidably sleeved on the tension wheels 247. Bottom shafts 248 are symmetrically installed on both sides at the lower end of the second fixed frame 241. The drive belts 242 are rotatably sleeved on the bottom shafts 248. Rotation grooves are formed in the upper push plate 244, and rollers 2441 are rotatably installed in the rotation grooves. The arrangement of the tension wheels 247 and the bottom shafts 248 enables the drive belts 242 to always be in a taut state, reducing slippage during the rotation of the drive belts 242 and facilitating the horizontal lifting of the upper push plate 244.

[0031] Working principle: When an unsealed bag with a specification of 20 - 50 KG is placed into the packaging machine, the shaping and flattening mechanism 2 starts to work. Through the pushing mechanism 21, one of the push plates 22 is pushed gradually closer to the other push plate 22 until the unsealed bag is flattened. At this time, the drive belts 242 on both sides of the push plate 22 are synchronously rotated. The drive motor 243 drives the drive wheel 246 to rotate slowly, and the drive wheel 246 is in transmission connection with the drive belts 242, enabling the drive belts 242 on both sides to be synchronously rotated, effectively saving manpower and material resources. It can drive the upper push plate 244 to move horizontally upward, so as to overcome the accumulation of the filling material in the lower part of the unsealed bag due to the gravity. At this time, when the two push plates 22 finally clamp the unsealed bag, the thickness of the material in the final vacuum packaging bag can be made relatively consistent.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
