Description

Technical Field

[0001] This utility model relates to the field of food preservation film production technology, and in particular to a vacuum device for PVC food preservation film winding products. Background Technology

[0002] During the production of PVC food wrap, a lot of air is trapped inside the roll during winding, forming small "air pockets." When the ambient temperature rises, such as in a warehouse in summer, a transport vehicle, or under sunlight, the trapped air expands. This expansion generates enormous inward or outward pressure. When this pressure exceeds the adhesive force between the film layers and the binding force of the roll core, it is suddenly released, causing the roll to loosen suddenly in certain areas, misalign between layers, or even the entire roll to burst open like a spring, becoming loose and irregular. Therefore, it is necessary to perform vacuum treatment on PVC food wrap rolls. Utility Model Content

[0003] The purpose of this utility model is to overcome the defects in the existing technology and provide a vacuuming device for PVC food preservation film roll products. By combining the shipping component, the fine-tuning component and the buffer component, the continuity of roll material transportation and production efficiency are improved. Moreover, the roll material after being vacuumed by the vacuum component is more rigid, dense, with neat edges and stable shape, which is more conducive to subsequent packaging, storage and transportation.

[0004] To achieve the above-mentioned technical effects, the technical solution of this utility model is: a vacuum device for PVC food preservation film rolling products, comprising: The vacuum assembly is connected to the base and is equipped with a support base and a sealing sleeve that can be fitted or separated.

[0007] A preferred technical solution is that the support base is rotatably connected to the base via a rotating shaft, the extension direction of the rotating shaft is consistent with the extension direction of the sealing sleeve, and the rotating shaft, through a driving component, directs the top opening of the support base toward the discharge side of the vacuum assembly.

[0008] A preferred technical solution is that the buffer component is sequentially connected with a first baffle, a core plate, and a second baffle. The length direction of the core plate is consistent with the axial direction of the sealing sleeve. The first baffle and the second baffle are respectively disposed on both sides of the core plate along the width direction and are rotatably connected to it.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0018] The terms "top," "bottom," "front," and "back" refer to the normal operating state of the vacuum device for PVC cling film roll products. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] like Figures 1-4 As shown, the arrows point from the feed side to the discharge side.

[0021] The vacuum device for PVC food preservation film roll products includes a vacuum component 2, a transport component 3, a fine-tuning component 30, and a buffer component 4. The vacuum component 2 is connected to the base 1 and is provided with a support base 21 that can be fitted together or separated from it and a sealing sleeve 20. The transport component 3 is located on the feed side of the vacuum component 2. The buffer component 4 is sandwiched between the transport component 3 and the vacuum component 2 and is used to transfer the roll material on the transport component 3 to the vacuum component 2. The fine-tuning component 30 adjusts the transport component 3 to move closer to or further away from the buffer component 4.

[0022] The vacuuming device continuously feeds the roll material from the preceding winding unit to the vacuum processing unit through the consignor, fine-tuning component, and buffer component, improving production efficiency. After vacuum processing by the vacuum component, the roll material becomes harder, denser, with neat edges and stable shape, which is more conducive to subsequent packaging, storage, and transportation. The consignor component allows for flexible sampling, and the buffer component facilitates vacuum processing of multiple roll materials and provides sufficient vacuum processing time.

[0023] like Figure 2 and 4 As shown, to optimize the structure of the vacuum assembly, the base 1 is equipped with a first guide member whose extension direction is consistent with the axial direction of the sealing sleeve 20. The sealing sleeve 20 reciprocates along the first guide member. The extension direction of the supporting base 21 is consistent with the axial direction of the sealing sleeve 20. The base 1 is equipped with a sealing rotating ring 200, which is in concave-convex fit with the free end of the sealing sleeve 20. The first guide member is a first guide screw. The sealing sleeve 20 is threadedly connected to the first guide screw via a slider. The first guide screw is driven to rotate by a motor, causing the slider to move, thereby realizing the reciprocating motion of the sealing sleeve 20 along the first guide member. This structure is hidden inside the connection between the sealing sleeve and the base and is not shown in the figure. The side wall of the sealing rotating ring 200 is provided with an air extraction port. In the actual assembled equipment, the vacuum assembly is also connected to a pressure gauge, which is not shown in the figure to detect the pressure inside the vacuum assembly.

[0024] In order to support multiple rolls of material and facilitate the placement of the rolls in a defined location and range, the cross-sectional width of the support base 21 gradually increases from bottom to top.

[0025] like Figure 4 As shown, the support base 21 is further rotatably connected to the base 1 via a rotating shaft 211. The extending direction of the rotating shaft 211 is consistent with the extending direction of the sealing sleeve 20. The rotating shaft 211, through a driving component, directs the top opening of the support base 21 toward the discharge side of the vacuum assembly 2. The rotating shaft 211 is also connected to a limiting component, which, under the combined action of the driving component and the limiting component, switches between keeping the top opening of the support base 21 facing upwards or toward the discharge side of the vacuum assembly 2. The driving component and the limiting component are not specifically shown.

[0026] likeFigures 1-2 As shown, the buffer component 4 is sequentially connected to a first baffle 41, a core plate 40, and a second baffle 42. The length direction of the core plate 40 is aligned with the axial direction of the sealing sleeve 20. The first baffle 41 and the second baffle 42 are respectively disposed on both sides of the core plate 40 along its width direction and are rotatably connected to it. The first baffle 41 is in contact with the transport component 3, and the second baffle 42 is in contact with the support base 21. Further, the back of the first baffle 41 and the second baffle 42 are provided with reinforcing ribs 401, one of which is connected to an angle adjusting component 43. The angle adjusting component 43 adjusts the first baffle 41 and the second baffle 42 to be coplanar with the upper surface of the core plate 40 or to form an obtuse angle. Specifically, when the first baffle 41 is coplanar with the upper surface of the core plate 40, it is in the state where the first baffle 41 is in contact with the transport component 3; when the second baffle 42 is coplanar with the upper surface of the core plate 40, it is in the state where the second baffle 42 is in contact with the support base 21. After completing the transport of a set of rolls, the first baffle 41 and the second baffle 42 are set at an obtuse angle to the upper surface of the core board 40, and the enclosed receiving cavity stores the pre-vacuum treated rolls.

[0027] like Figure 1 As shown, the production equipment for the roll material is set by the manufacturer, and the height of the winding unit is fixed. To facilitate the handling of the finished product after vacuum treatment, a relatively low operating platform is generally set up. To ensure seamless connection between the vacuum device and the production setup, and to facilitate smooth transport of the roll material, the fine-tuning component 30 includes a second guide component 301, a lifting component 302, and an tilting component 303. The extension direction of the second guide component 301 is perpendicular to the extension direction of the first guide component, and the transport component 3 reciprocates along the second guide component. The lifting component 302 is used to adjust the supporting surface of the transport component 3 to be flush with the first baffle 41. The tilting component 303 adjusts the supporting surface of the transport component 3 to be tilted towards the first baffle 41. The second guide component is a second guide screw; the thread is not shown in the figure to simplify the second guide component. The second guide component is also connected to a motor, which drives the transport component threadedly connected to it through rotation. The fine-tuning component 30, composed of the second guide component 301, the lifting component 302, and the tilting component 303, enables flexible sampling and sample delivery.

[0028] Furthermore, a first anti-slip layer is provided on the surface of the consignment 3. The first anti-slip layer can be an anti-slip coating or, in actual production, an elastic band, cotton cloth, or a substandard film material. For example, the elastic band is wrapped around the width of the consignment to form a first anti-slip layer that extends along the width direction and is arranged sequentially in the length direction; or cotton cloth is laid and fixed on its surface to form a first anti-slip layer.

[0029] When the first baffle 41 is in contact with the transport piece 3, since the supporting surface of the transport piece 3 is flush with the first baffle 41, a second anti-slip layer is provided on the front side of the first baffle 41 to ensure the roll material is stably conveyed to the buffer and to prevent reverse rolling. The front side of the second baffle 42 is a smooth surface. When the second baffle 42 is in contact with the support base 21, the support base 21 is concave, preventing reverse rolling. To quickly and accurately convey the roll material to the support base 21, the front side of the second baffle 42 is also made smooth.

[0030] In order to optimize the structure of the vacuum device and smoothly collect the vacuum-treated roll material and send it to the next process, the vacuum component 2 is further provided with a finished product support 5 on the discharge side, and the support surface of the finished product support 5 is a smooth surface.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
