Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum sealing equipment, and relates to a vacuum sealing auxiliary device and a vacuum sealing device for packaging fruit and vegetable raw materials. Background Technology

[0002] In the food processing of pre-processed vegetables such as fresh-cut fruits and vegetables, vacuum sealing is required to extend their shelf life. This operation is typically performed on a plastic bag vacuum sealing device. Currently, during vacuum sealing, the basket containing the vegetables is placed at the vacuum sealing station, where the equipment directly vacuums and seals the bag. However, this method has a significant drawback: after vacuuming and shrinking, the bag lifts the material up, causing it to detach from the bottom plate. This results in the entire weight being concentrated in the sealing area during heat sealing, leading to unstable sealing quality. Not only is the seal ineffective, but the sealed area is also prone to deformation and poor strength.

[0003] This utility model is proposed based on this. Utility Model Content

[0004] The purpose of this utility model is to provide a vacuum sealing auxiliary device and a vacuum sealing device for packaging fruit and vegetable raw materials, so as to improve the vacuum sealing quality of fruit and vegetable raw materials.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] In one aspect, this utility model provides a vacuum sealing auxiliary device for packaging fruit and vegetable raw materials, comprising:

[0007] The ingredient basket includes a basket body surrounded by four side panels and a lifting bottom plate that can slide up and down along the inner wall of the basket body.

[0008] The lifting mechanism installed at the vacuum sealing station includes a basket support that can support the batching basket and a lifting component located below the basket support that can move up and down. The lifting component can push the lifting base plate upward and drive it to rise along the inner wall of the basket body within a set stroke.

[0009] Furthermore, a support plate can be provided above the lifting base plate as needed, and a fixed connecting plate is provided between the lifting base plate and the support plate. The fixed connecting plate and the support plate can be used to easily adjust the height of the base, so that in some cases the lifting cylinder and lifting module cannot reach the set height requirement.

[0010] Furthermore, the bottom end of the basket body also protrudes laterally to form a limiting protrusion that supports the lifting base plate.

[0011] Furthermore, the area enclosed by the limiting protrusion also has a clearance area for the lifting component to extend into.

[0012] Furthermore, the lifting base plate and the inner wall of the basket body are fitted with a sliding clearance.

[0013] Furthermore, the lifting assembly includes a lifting cylinder and a lifting plate connected to and moving with the lifting cylinder. When the lifting cylinder lifts upward, the lifting plate rises with it and can pass through the basket bracket to support the lifting base plate.

[0014] Furthermore, a lifting module that can move up and down is provided next to the vacuum sealing station. The basket bracket is connected to the lifting module and moves up and down through the lifting module, thereby driving the entire batching basket to rise and fall.

[0015] Furthermore, the basket support is in the form of a fork.

[0016] Furthermore, both the side plate and the lifting base plate are provided with perforated holes.

[0017] In a second aspect, this utility model provides a vacuum sealing device for packaging fruit and vegetable raw materials, comprising:

[0018] The vacuum sealing auxiliary device described in the first aspect above;

[0019] Conveyor rollers for transporting the ingredient baskets;

[0020] And a vacuum sealing mechanism, which is set above the vacuum sealing station and is used to vacuum seal the packaging bags in the batching baskets sent to the vacuum sealing station.

[0021] This invention, through research, reveals that because fruits and vegetables are generally large in weight and volume, and especially vegetables are relatively loose when initially packed, the volume of the packaging bag changes significantly during vacuum sealing. In other words, the entire packaging bag, with the vacuum sealing point as its support, effectively rises and becomes suspended. Under the weight of the entire packaging bag, the heat-sealing area inevitably experiences stretching and deformation, severely affecting the sealing performance, strength, and consistency of the sealing area. Therefore, this invention incorporates a lifting component to drive the lifting base plate up and down. During vacuum sealing, the lifting component and basket support rise in coordination, causing the lifting base plate to rise synchronously. This ensures that the packaging bag containing the fruits and vegetables is always supported and not suspended, effectively eliminating the impact of the packaging bag and its contents' weight on the sealing quality.

[0035] To improve the quality of vacuum sealing for fruit and vegetable raw material packaging, this utility model provides a vacuum sealing auxiliary device for fruit and vegetable raw material packaging, the structure of which is described below. Figures 1 to 5 As shown, it includes:

[0036] The ingredient basket includes a basket body surrounded by four side panels and a lifting bottom plate that can slide up and down along the inner wall of the basket body.

[0037] The lifting mechanism installed at the vacuum sealing station includes a basket support that can support the batching basket and a lifting component located below the basket support that can move up and down. The lifting component can push the lifting base plate upward and drive it to rise along the inner wall of the basket body within a set stroke.

[0038] In some specific embodiments, a support plate is also provided above the lifting base plate, and a fixed connecting plate is provided between the lifting base plate and the support plate.

[0039] In some specific embodiments, the bottom end of the basket body also protrudes laterally to form a limiting protrusion that supports the lifting base plate, which can support and hold the lifting base plate and other components to prevent them from detaching from the basket body during lifting.

[0040] In a more specific embodiment, the area enclosed by the limiting protrusion also has a clearance area for the lifting component to extend into, so that the lifting component can pass through the basket bracket during the lifting process and thus lift the lifting base plate.

[0041] In some specific embodiments, the lifting base plate and the inner wall of the basket body are in a sliding clearance fit. Specifically, the lifting base plate and the basket body can adopt a conventional sliding fit method of slider and slide rail, or other methods that can achieve a sliding connection between the lifting base plate and the basket body.

When the lifting cylinder lifts upward, the lifting plate rises with it and can pass through the basket bracket to support the lifting base plate.

[0043] In some specific embodiments, a lifting module capable of vertical movement is also provided next to the vacuum sealing station. The basket support is connected to the lifting module and moves up and down through the lifting module, thereby lifting the entire batching basket. The lifting module here can be any conventional module component capable of lifting in the art, such as a commonly used linear slide module (servo motor lifting module), etc. Its specific structure is not an innovative point of this utility model and will not be described further here.

[0044] In some specific embodiments, the basket support is in the shape of a fork, which allows it to pass easily through the conveyor rollers during lifting.

[0045] In some specific embodiments, both the side plate and the lifting base plate are provided with perforated holes.

[0046] Each of the above implementation methods can be implemented individually, or in any combination of two or more.

[0047] The above implementation methods will be described in more detail below with reference to specific embodiments.

[0048] Example 1:

[0049] To improve the quality of vacuum sealing for fruit and vegetable raw material packaging, this utility model provides a vacuum sealing auxiliary device for fruit and vegetable raw material packaging, the structure of which is described below. Figures 1 to 5 As shown, it includes:

[0050] The ingredient basket includes a basket body surrounded by four side panels and a lifting bottom plate that can slide up and down along the inner wall of the basket body.

[0051] The lifting mechanism installed at the vacuum sealing station includes a basket support that can support the batching basket and a lifting component located below the basket support that can move up and down. The lifting component can push the lifting base plate upward and drive it to rise along the inner wall of the basket body within a set stroke.

[0052] Please see again. Figure 5 As shown, a support plate is also provided above the lifting base plate, and a fixed connecting plate is provided between the lifting base plate and the support plate. Both the side plate and the lifting base plate have perforations.

[0053] Please see again. Figure 5As shown, the bottom end of the basket body also protrudes laterally to form a limiting protrusion that supports the lifting base plate. This protrusion supports the lifting base plate and other components, preventing them from detaching from the basket body during lifting. The area enclosed by the limiting protrusion also has a clearance area for the lifting assembly to extend into, allowing the lifting assembly to pass through the basket support and lift the lifting base plate during lifting. The lifting base plate and the inner wall of the basket body are in a sliding clearance fit. Specifically, the lifting base plate and the basket body can use a conventional sliding fit between a slider and a slide rail, or other methods that enable a sliding connection between the lifting base plate and the basket body. The specific structure of the sliding fit is not an innovation claimed by this utility model and will not be elaborated upon here.

[0054] Please see again. Figure 1 As shown, the lifting assembly includes a lifting cylinder and a lifting plate connected to and moving with the lifting cylinder. When the lifting cylinder lifts upward, the lifting plate rises with it and can pass through the basket bracket to support the lifting base plate.

[0055] Please see again. Figure 1 As shown, a lifting module capable of moving up and down is also provided next to the vacuum sealing station. The basket support is connected to the lifting module and moves up and down through the lifting module, thereby lifting the entire batching basket. The lifting module here can use conventional module components that can achieve lifting functions, such as commonly used linear slide modules (servo motor lifting modules), etc. Its specific structure is not an innovative point of this utility model and will not be described in detail here.

[0056] Please see again. Figure 1 As shown, the basket support is a U-shaped fork, which allows it to easily pass through the conveyor rollers during lifting.

[0057] The working principle of the device in this embodiment is as follows:

[0058] The ingredient baskets are transported to the sealing station via a conveyor roller conveyor. Here, the lifting module operates first, raising the basket support frame above the conveyor roller conveyor. This supports the bottom of the ingredient basket as it continues to rise, allowing the vacuum sealing mechanism above the sealing station to grasp the upper edge of the packaging bag inside the basket. Then, the lifting module lowers the basket, facilitating the vacuum sealing mechanism to remove and open the folded-out area of ​​the packaging bag. Subsequently, the lifting assembly rises, lifting the lifting base plate (connected to the support plate) to the target height. Next, the lifting module raises the ingredient basket along with the basket, and the vacuum sealing mechanism simultaneously performs and completes the vacuuming and sealing operations. During this process, the lifting action of the base plate and other components causes the packaging bag containing vegetables and other raw materials to move upwards simultaneously, ensuring that the bottom of the packaging bag does not detach from the support plate during vacuum sealing, thus preventing its own weight from affecting the sealing area. After the vacuum sealing operation is completed, the lifting component retracts, the lifting module resets, and the batching basket falls onto the conveyor rollers and is sent out.

[0059] Example 2:

[0060] Based on Embodiment 1, this embodiment proposes a vacuum sealing device for packaging fruit and vegetable raw materials. In addition to the aforementioned vacuum sealing auxiliary device, it includes a conveyor roller conveyor for transporting the ingredient baskets, and a vacuum sealing mechanism positioned above the vacuum sealing station to vacuum seal the packaging bags in the ingredient baskets delivered to the vacuum sealing station. It should be noted that the vacuum sealing mechanism is a conventional packaging bag sealing device and is not an innovation protected by this invention; therefore, it will not be elaborated upon further.

[0061] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
