Technical Field

[0001] This utility model relates to the field of fruit canning technology, specifically to a fruit canning vacuum sealing device. Background Technology

[0002] Vacuum sealing of fruit cans refers to the process of filling fruit into a canning container and then using vacuum technology to remove the air from the container, creating a vacuum environment to achieve the purposes of preservation, anti-corrosion, and moisture prevention.

[0003] Conventional fruit canning involves placing large quantities of canned fruit directly into vacuum sealing equipment for processing. However, this can lead to some cans not being properly processed, thus affecting product quality. It is also difficult to effectively vacuum individual cans. Summary of the Invention

[0004] The purpose of this invention is to provide a vacuum sealing device for canned fruit to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum sealing device for fruit cans, comprising a base assembly and an auxiliary exhaust assembly. An adjustment assembly is vertically installed on one side of the base assembly. The auxiliary exhaust assembly is connected to the adjustment assembly on the side near the vertical central axis of the base assembly. Limiting components are symmetrically arranged on the left and right sides directly below the auxiliary exhaust assembly. The auxiliary exhaust assembly includes a moving platform, a support frame, a connecting valve, and a suction hood. The support frame is installed on the top of the end of the moving platform away from the adjustment assembly, and a connecting valve is installed on the top of the support frame. The suction hood is connected to the bottom of the connecting valve.

[0006] Furthermore, the base assembly includes a base, a placement platform, support piles, and an electric push rod. The placement platform is installed on the top of the base, and support piles are symmetrically installed on both the left and right sides of the base. An electric push rod is horizontally installed on the top of each support pile.

[0007] Furthermore, the support pile is arranged in an "L" shape and is fixedly connected to the base, and the top surface of the placement platform is provided with a circular groove structure for limiting the placement of the cans.

[0008] Furthermore, the adjustment assembly includes a pile, a fixing frame, a vacuum motor, a lead screw, and a guide rail. The fixing frame is installed on the upper end of the pile near the vertical central axis of the base assembly, and the vacuum motor is installed on the top of the fixing frame. The bottom power output end of the vacuum motor is vertically connected to the lead screw through a coupling. The guide rails are symmetrically and vertically installed on the surface of the pile near the vertical central axis of the base assembly.

[0009] Furthermore, the guide rails are vertically arranged on the left and right sides of the lead screw, and the guide rails and the lead screw are parallel to each other, and the upright pile is vertically fixed to one side of the base.

[0010] Furthermore, the movable stage is combined with the guide rail and the lead screw in a slotted embedded structure and a threaded connection, and the upper side of the connecting valve is provided with a quick connector structure for connecting with an external vacuum pump via a pipeline.

[0011] Furthermore, the limiting component includes a connecting frame, a buffer frame, an arc-shaped clamp, and a docking seat. The connecting frame is equipped with buffer frames at both ends, and the end of the buffer frame away from the connecting frame is connected to the arc-shaped clamp. The connecting frame is provided with docking seats at both ends on the side away from the arc-shaped clamp.

[0012] Furthermore, the docking seat and the connecting frame are integrated into one structure, and the output end of the electric push rod is connected to the docking seat.

[0013] This utility model provides a vacuum sealing device for canned fruit, which has the following beneficial effects:

[0014] 1. This utility model, by setting up an auxiliary exhaust component, wherein the entire device is set inside the vacuum chamber, and the top of the can to be vacuumed is set inside the vacuum hood. The vacuum hood, made of elastic rubber material, is tightly fitted to the top of the can. At the same time, by using the structure of the connecting valve and the hose structure, the auxiliary exhaust component can be connected and combined with the external vacuum pump. With the above structure, it can help to ensure the vacuum treatment effect of the can as much as possible during the vacuum sealing process inside the vacuum chamber, and avoid the situation of insufficient vacuuming effect.

[0015] This invention incorporates an adjustment component, in which the movable stage is connected to a lead screw and guide rail. When the vacuum motor operates, it drives the lead screw to rotate axially in the vertical direction, thereby causing the entire auxiliary exhaust assembly to vertically rise and fall along the surface of the lead screw and guide rail. This structure allows for appropriate structural adjustments to the auxiliary exhaust assembly within a certain range, based on the height and dimensions of the can, thus improving the applicability and flexibility of the device. Furthermore, the vacuum motor is specially designed and optimized to operate stably under vacuum conditions, avoiding problems such as poor heat dissipation, material evaporation, or lubrication failure caused by rarefied gas.

[0016] This invention further incorporates a limiting component connected to one end of the electric push rod. Under the structural operation of the electric push rod, its horizontal extension and retraction adjustment drives the docking seat and connecting frame to move horizontally synchronously. Then, the arc-shaped clamping plate on the other side is pushed against the side surface of the can, forming a left-right clamping structure. This structure allows for structural adjustment and limiting based on the size of the can within a certain range. Furthermore, the buffer frame provides a degree of cushioning between the structures, reducing the impact of excessive clamping on the can. The electric push rod is designed for vacuum environments, operating at a vacuum level of 10^-7 Pa and suitable for high and low temperature environments ranging from -60℃ to 85℃. This electric push rod design considers the special requirements of vacuum environments, with main components made of stainless steel or materials with comparable thermal expansion coefficients and low gas exudation rates to ensure stable operation in high vacuum and high / low temperature environments.

The electric push rod 104 is horizontally installed on the top of the support posts 103. The support posts 103 are arranged in an "L" shape and are fixedly connected to the base 101. The top surface of the placement platform 102 has a circular groove structure for limiting the placement of cans. The limiting assembly 4 includes a connecting frame 401, a buffer frame 402, an arc-shaped clamp 403, and a docking seat 404. 4.

A docking seat 404 is provided at both ends of the side of the connecting frame 401 away from the arc-shaped clamping plate 403. The docking seat 404 and the connecting frame 401 are integrated into one structure. The output end of the electric push rod 104 is connected to the docking seat 404. When the vacuum motor 203 operates, it will drive the lead screw 204 connected to it to rotate axially in the vertical direction, thereby driving the entire auxiliary exhaust assembly 3 to vertically rise and fall along the surface of the lead screw 204 and the guide rail 205.

[0026] like Figures 1 to 5As shown, the adjustment assembly 2 includes a post 201, a fixing frame 202, a vacuum motor 203, a lead screw 204, and a guide rail 205.

[0029] Then, under the operation of the vacuum motor 203 at the top of the fixed frame 202, the lead screw 204 connected to its bottom will rotate axially in the vertical direction, thereby driving the entire auxiliary exhaust assembly 3 connected to it via the moving table 301.
