Description

Technical Field

[0001] This utility model belongs to the field of food packaging technology, and in particular to a cold chain temperature-controlled packaging device for fresh food. Background Technology

[0002] The food cold chain was established with the advancement of science and technology and the development of refrigeration technology. It is a logistics phenomenon under low-temperature conditions based on cryogenics and using refrigeration technology.

[0003] Most existing cold chain temperature-controlled packaging devices for fresh food involve manually opening the packaging bag, then feeding the cold chain food to be packaged into the bag via a conveyor belt, and finally sealing the packaged bag. This packaging method requires manual assistance and cannot complete the packaging and sealing process in one go, thus greatly reducing the packaging efficiency of fresh food. Therefore, there is an urgent need for a new cold chain temperature-controlled packaging device for fresh food to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a temperature-controlled cold chain packaging device for fresh food to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cold chain temperature-controlled packaging device for fresh food, comprising two vertical plates for installing the cold chain temperature-controlled packaging device for fresh food and a conveyor belt for conveying fresh food, wherein an inclined plate and a guide plate are fixedly connected between the two vertical plates, and the guide plate is located above the inclined plate, and a lower hook bag plate is fixedly connected to the upper end of one side of the inclined plate.

[0006] Two vertical plates are symmetrically provided with vertical grooves on opposite sides. A slider is slidably installed inside the vertical groove. A tension spring is fixedly connected to the top surface of the slider. The top surface of the tension spring is fixedly connected to the upper end of the vertical groove. A horizontal plate is fixedly connected between the two sliders. An upper hook bag plate is fixedly connected to the side wall of the horizontal plate and the lower hook bag plate.

[0007] An installation plate is fixedly connected between the two vertical plates. A cylinder is fixedly installed on the top surface of the installation plate. The telescopic end of the cylinder extends to the bottom of the installation plate and is fixedly connected to a heat-pressing sealing plate for temperature-controlled packaging of fresh food.

[0008] Preferably, two limiting blocks are symmetrically fixedly connected to the side walls of the two sliders, and two limiting grooves are symmetrically opened on the inner wall of the vertical groove.

[0009] Preferably, the two limiting blocks fixedly connected to the sidewall of the slider are slidably connected to the inside of the two limiting grooves opened on the inner wall of the vertical groove.

[0010] Preferably, the top surface of the hot-pressed sealing plate is symmetrically and fixedly connected with two limiting rods, and the top surface of the mounting plate is provided with two sliding holes corresponding to the two limiting rods.

[0011] Preferably, the two limiting rods on the top surface of the hot-pressed sealing plate slide through the two sliding holes and extend above the mounting plate.

[0012] Preferably, the bottom of the hot-pressed sealing plate has the same inclination angle as the inclined plate.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This cold chain temperature-controlled packaging device for fresh food utilizes an upper hook bag plate, a lower hook bag plate, a slider, and a tension spring. After the opening of the packaging bag is opened, it is hung between the upper hook bag plate and the lower hook bag plate. Then, the tension spring pulls the horizontal plate and the upper hook bag plate upward, thereby separating the upper hook bag plate and the lower hook bag plate and opening the packaging bag. The fresh food to be packaged is then conveyed down to the guide plate by the conveyor belt, and then slides into the inside of the packaging bag through the guide plate.

[0015] This cold chain temperature-controlled packaging device for fresh food benefits from the setting of cylinders and hot-press sealing plates. When the fresh food in the packaging bag is filled to a sufficient amount, the cylinder is activated to simultaneously heat the hot-press sealing plate and push the hot-press sealing plate up and down on the inclined plate to seal the packaging bag on the inclined plate. This allows the fresh food to be sealed immediately after packaging, thereby preventing the invasion of bacteria in the air and further improving packaging efficiency.

[0016] Compared with existing technologies, this cold chain temperature-controlled packaging device for fresh food can effectively control the temperature of fresh food while simultaneously performing packaging and sealing operations, thereby further improving the packaging efficiency of fresh food.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] like Figures 1 to 4 A temperature-controlled cold chain packaging device for fresh food is shown below:

[0028] The main structure consists of two vertical plates 1 for installing a cold chain temperature-controlled packaging device for fresh food and a conveyor belt 2 for conveying fresh food. An inclined plate 3 and a guide plate 15 are fixedly connected between the two vertical plates 1. The conveyor belt 2 is located above the guide plate 15, and the guide plate 15 is located above the inclined plate 3, so that the fresh food on the guide plate 15 can slide down to the top of the inclined plate 3, which facilitates the packaging of the fresh food. A hook bag plate 4 is fixedly connected to the upper end of one side of the inclined plate 3.

[0029] Two vertical plates 1 are symmetrically provided with vertical grooves 7 on opposite sides. A slider 8 is slidably installed inside the vertical groove 7. A tension spring 9 is fixedly connected to the top surface of the slider 8. The top surface of the tension spring 9 is fixedly connected to the upper end of the vertical groove 7. A horizontal plate 5 is fixedly connected between the two sliders 8. An upper hook bag plate 6 is fixedly connected to the side wall of the horizontal plate 5 and the lower hook bag plate 4. Thanks to the arrangement of the upper hook bag plate 6, the lower hook bag plate 4, the slider 8 and the tension spring 9, after the opening of the packaging bag is opened, it is hung between the upper hook bag plate 6 and the lower hook bag plate 4 respectively. Then, the tension spring 9 pulls the horizontal plate 5 and the upper hook bag plate 6 to move upward, thereby separating the upper hook bag plate 6 and the lower hook bag plate 4, thus opening the packaging bag. Then, the fresh produce to be packaged is conveyed down to the guide plate 15 by the conveyor belt 2, and then slides into the inside of the packaging bag through the guide plate 15.

[0030] An installation plate 10 is fixedly connected between two vertical plates 1. A cylinder 11 is fixedly installed on the top surface of the installation plate 10. The telescopic end of the cylinder 11 extends to the bottom of the installation plate 10 and is fixedly connected to a heat-sealing plate 12 for temperature-controlled packaging of fresh food. Thanks to the cylinder 11 and the heat-sealing plate 12, when the fresh food in the packaging bag is filled to a sufficient amount, the cylinder 11 is activated to simultaneously activate the heat-sealing plate 12 for heating. The cylinder 11 pushes the heat-sealing plate 12 up and down against the inclined plate 3 to seal the packaging bag on the inclined plate 3. This allows the fresh food to be sealed immediately after packaging, thereby preventing the invasion of bacteria in the air and further improving packaging efficiency.

[0031] Two limiting blocks 13 are symmetrically fixedly connected to the side walls of the two sliders 8. Two limiting grooves are symmetrically opened on the inner wall of the vertical groove 7. The two limiting blocks 13 fixedly connected to the side walls of the sliders 8 are slidably connected to the two limiting grooves opened on the inner wall of the vertical groove 7. Thanks to the setting of the limiting blocks 13, the sliding direction of the sliders 8 and the horizontal plate 5 can be effectively limited, and the stability of the horizontal plate 5 during sliding can be further improved.

[0032] Two limiting rods 14 are symmetrically fixedly connected to the top surface of the hot-press sealing plate 12. Two sliding holes are opened on the top surface of the mounting plate 10 corresponding to the two limiting rods 14. The two limiting rods 14 on the top surface of the hot-press sealing plate 12 slide through the two sliding holes and extend to the top of the mounting plate 10. Thanks to the setting of the limiting rods 14, the sliding direction of the hot-press sealing plate 12 can be limited by the limiting rods 14.

[0033] The bottom of the heat-sealing plate 12 and the inclined plate 3 are set at the same angle, so that the bottom of the heat-sealing plate 12 and the top surface of the inclined plate 3 can fit more closely, thereby further improving the sealing effect on the packaging bag.

[0034] Working principle

[0035] When using this cold chain temperature-controlled packaging device for fresh food, firstly, the cylinder 11 is activated to lift the heat-sealing plate 12, which is fixedly connected to its telescopic end, upwards. Then, the opening of the packaging bag is respectively placed between the lower hook bag plate 4 and the upper hook bag plate 6. Then, the tension spring 9 drives the slider 8 and the horizontal plate 5, which are fixedly connected to it, to move upwards, and at the same time, drives the upper hook bag plate 6 to move upwards, thereby opening the packaging bag. Then, the fresh food to be packaged is transported to the upper end of the guide plate 15 by the conveyor belt 2. Then, the fresh food to be packaged enters the packaging bag through the guide plate 15. Then, the heat-sealing plate 12 is activated first for preheating. Then, the cylinder 11 is activated to push the heat-sealing plate 12 downwards until the packaging bag on the inclined plate 3 is sealed.
