Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing machines in food packaging, and more particularly to vacuum sealing machines. Background Technology
[0002] Sealing machines are commonly used small appliances for food storage. They can separate different types of food into individual portions for easy storage during food sorting or storage.
[0003] However, in the current sealing machine, the sealing bag is directly inserted and then sealed. In this process, the sealing bag is not well extended and fixed. In vacuum sealing, the sealing bag cannot be well temporarily fixed, which will cause movement and affect the sealing effect. Utility Model Content
[0004] The purpose of this invention is to provide a vacuum sealing machine that ensures stability during vacuum sealing and improves the sealing effect through introduction in one direction and guidance and positioning in another direction.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.
[0006] A vacuum sealing machine includes a base and an upper cover rotatably connected to the base. The base is provided with at least one guide mechanism, each of which forms a guide path for the sealing bag in a first direction and a temporary locking position for the sealing bag in a second direction.
[0007] The base has a bearing surface, and a sealing space is formed between the bearing surface and the compression surface of the top cover. The sealing space forms an introduction path for the sealing bag along a first direction.
[0008] Furthermore, the guiding mechanism includes a guide member constituting the guiding path and a locking member forming the temporary locking position, with the two locking members located on both sides of the guide member.
[0009] Furthermore, the two locking elements form a narrowing locking trend with gradually decreasing width along the innermost side to the outermost side of the introduction path.
[0010] Furthermore, the side of the card slot member facing the downward guide member forms a downward pressing surface, which forms a downward pressing trend from the innermost side to the outermost side along the introduction path.
[0011] Furthermore, the guiding mechanism also includes a mounting post, which extends upward and is fitted with a U-shaped structure. The two sides of the U-shaped structure constitute the locking member, and a partial protrusion at the top of the mounting post forms the guiding member.
[0012] Furthermore, the mounting post has an inclined surface at its top that slopes toward the locking element, located on the side near the sealing bag inlet path.
[0013] Furthermore, the guiding path forms a wave-like structure with both upward and downward guiding trends along the first direction.
[0014] Furthermore, the base is provided with a compression cavity, and the guide mechanism is fixedly connected to the compression cavity.
[0015] Furthermore, an annular assembly cavity is formed on the outer periphery of the extrusion cavity, and an annular sealing ring is provided inside the annular assembly cavity. The guide mechanism is located inside the annular assembly cavity and is disposed in close contact with the inner wall of the annular sealing ring.
[0016] Furthermore, the base is partially recessed to form an assembly groove, and the guide mechanism is partially embedded in the assembly groove.
[0017] The beneficial effects of this utility model are as follows:
[0018] In this invention, by adding guides and temporary fixing positions, the stability and temporary fixation of the sealing bag are ensured during the sealing process, avoiding the problem of the sealing bag shifting due to the force generated during compression, which would cause the seal to deviate.

Detailed Implementation
[0026] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, it should be noted that these embodiments are not intended to limit the present invention. Equivalent transformations or substitutions in function, method, or structure made by those skilled in the art based on these embodiments are all within the protection scope of the present invention.
[0027] See attached document Figure 1-5 As shown, the vacuum sealing machine in this embodiment includes a base 100 and a top cover 200 rotatably connected to the base 100. The base 100 is provided with at least one guide mechanism 300. Each guide mechanism 300 forms a guide path for the sealing bag along a first direction and a temporary holding position for the sealing bag along a second direction. For carrying the sealing bag, the base 100 has a bearing surface 110. A sealing space is formed between the bearing surface 110 and the compression surface 210 of the top cover 200. The sealing space forms an introduction path for the sealing bag along the first direction. In this embodiment, different numbers of guide mechanisms can be set according to the size of the sealing machine, but all guide mechanisms are located in the same directional position, such as the innermost side.
[0028] In practical use, firstly, the sealing point of the sealing machine forms the first direction from front to back (i.e., the general Z-axis). That is, the sealing bag generally moves back and forth from the outside to the inside to put in or take out the sealing bag. During this process, the sealing bag has a large area, and wrinkles are inevitably generated when it is put in, making the sealing surface uneven. At this time, it can be adjusted by guiding.
[0029] Secondly, a second direction (i.e., the Y-axis) is formed in the height direction, and then the guiding mechanism forms a temporary stop, so that the extended sealing bag is temporarily stopped at the guiding mechanism. As the sealing bag extends from front to back, it has been guided by the guiding path, reducing the wrinkles generated at the guiding mechanism.
[0030] Finally, in vacuum sealing, where the sealing width is generally limited, the guide mechanism can be placed at the sealing position to improve sealing efficiency.
[0031] The specific details regarding the guiding institutions are as follows:
[0032] See attached document Figure 3-4 As shown, the guiding mechanism 300 includes a guide member 310 constituting the guiding path and a locking member 320 forming the temporary locking position. The two locking members 320 are located on both sides of the guide member 310. At this time, the locking members provide a certain degree of lateral protection for the guide member, thus providing a foundation for subsequent high-efficiency guidance, etc.
[0033] See attached document Figure 3-4It can be seen that the two locking pieces 320 form a narrowing locking trend with gradually decreasing width from the innermost side to the outermost side along the introduction path. This narrowing locking trend means that when the sealing bag enters, it enters from the smallest side, and then gradually increases the distance between the two locking pieces 320 inwards. That is, it is inserted from the outside to the inside along the opposite direction of the narrowing locking trend, and the width of the inner locking becomes larger and larger, making it easier for the sealing bag to enter the inside after being subjected to force.
[0034] To ensure the sealing bag is initially secured beneath the locking member 320, a downward-facing guide surface is formed on one side of the locking member 320. Along the innermost to outermost side of the introduction path, this downward-facing surface exhibits a downward-pressing trend, first downward and then upward. That is, in the opposite direction of the introduction path, it's downward then upward; conversely, in the direction of the introduction path, it's upward then downward. The sealing bag enters the innermost side via an upward-downward trajectory. This vertical variation in height creates a trajectory characteristic of the sealing bag moving from a low point to a high point and then back to a low point within the introduction path, making it less prone to falling off under pressure. This structure is also simple, simplifying customer operation and improving user experience. Viewed from the side, the guide member 310 is pointed, then forms sloping structures on both the front and rear sides.
[0035] To facilitate fixing and stabilize the locking and guiding components, a mounting post 330 is also included. The mounting post 330 extends upward and is fitted with a U-shaped structure. The two sides of the U-shaped structure form the locking component 320. The top of the mounting post 330 has a partial protrusion to form the guiding component 310. At this time, the guiding mechanism can also be produced as a whole using a mold, so that it simultaneously has a mounting post, a guiding component, and a locking component.
[0036] In this embodiment, since the sealing bag gradually approaches the mounting post from a distance, in order to guide it, the mounting post 330 forms an inclined surface 331 on the side near the sealing bag's introduction path, which is inclined towards the locking component. In use, after the sealing bag approaches the inclined surface 331, it is guided by the inclined surface to approach the guide and locking component, preparing for better subsequent extension.
[0037] Specifically, in this embodiment, the guide path forms a wave-shaped structure with an upward and downward guiding trend along the first direction. The upper and lower paths can be sequential or multiple undulations of equal or different heights can be set to facilitate fixing the sealing bag.
[0038] The installation process for the guiding mechanism, etc., is described below:
[0039] Specifically, for the existing base, a squeezing cavity 120 can be provided on the base 100, and the guide mechanism 300 is fixedly connected to the squeezing cavity 120. In order to cooperate with the squeezing at the sealing point of the sealing bag and avoid the influence of force, a fixed assembly method can be selected to fix the guide mechanism 300 in the squeezing cavity 120.
[0040] During assembly, in order to ensure the sealing of the sealing bag opening, an annular assembly cavity 130 is formed on the outer periphery of the extrusion cavity 120. An annular sealing ring 140 is provided in the annular assembly cavity 130. The guide mechanism 300 is located inside the annular assembly cavity 130 and is set in close contact with the inner wall of the annular sealing ring 140. At this time, the annular sealing ring 140 can seal the guide mechanism 300 locally.
[0041] In this embodiment, in order to ensure tight assembly, the base 100 is partially recessed to form an assembly groove 150, and the guide mechanism 300 is partially embedded in the assembly groove 150.
[0042] See attached document Figure 1-5 As shown, in this embodiment, the two ends of the annular sealing ring 140 extend outward and abut against the base 100, and then it forms a enclosure cavity. The guide mechanism 300 is placed in the enclosure cavity, and the entire guide mechanism 300 is above the sealing ring, so that it can have a good sealing effect while sealing.
[0043] In this embodiment, corresponding annular assembly cavities and annular sealing rings can also be set at the positions corresponding to the upper cover 200, the annular assembly cavity 130, and the annular sealing ring 140, respectively, and finally the extrusion cavity is realized through the two annular assembly cavities and the annular sealing ring. Of course, the annular assembly cavities and annular sealing rings here are set lower than the bearing surface and the extrusion surface.

All equivalent implementations or modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
[0045] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
