Description

Technical Field

[0001] This utility model relates to the field of vacuum machine technology, and in particular to a vacuum sealing machine with a telescopic guide component. Background Technology

[0002] A vacuum sealer is a device used to seal food, medicine, and other items. It works by removing air from the packaging, creating a low-oxygen environment that helps extend the shelf life of the goods and prevents oxidation and bacterial growth. Vacuum sealers are frequently used in homes, restaurants, and the food processing industry to maintain food freshness and extend its shelf life.

[0003] Existing vacuum pumps have an extraction port inside the vacuum chamber to remove gas from the vacuum bag and achieve vacuum sealing. However, in actual use, the sealing ring around the vacuum chamber is too tight, which blocks the air passage of the vacuum bag and affects the efficiency of the extraction port. To better extract gas from the vacuum bag, a telescopic guide is installed in the main body. However, when the cover is closed, the existing telescopic guide is squeezed against the sealing ring due to the fastening force. With repeated use, the sealing ring is prone to deformation at the corresponding position, affecting the vacuum pump's vacuuming effect. Utility Model Content

[0008] The main body has a cavity, and a telescopic flow guiding mechanism is provided inside the cavity;

[0009] The first panel has a lower chamber formed on the side near the cover, and a protrusion is formed on one side of the lower chamber port toward the cover.

[0011] As a further improvement, the telescopic flow guiding mechanism is provided with a flow guide plate. The flow guide plate has multiple air guiding channels at its first end, which are used to guide gas into the lower chamber. The flow guide plate is connected to a slider at its second end.

[0012] As a further improvement, the telescopic flow guiding mechanism also includes a housing and a sealing shell. The sealing shell is disposed outside the housing, and a third sealing ring is provided at the connection between the sealing shell and the cover. The housing is provided with multiple slide rails, and a slider is slidably disposed on the slide rails. The first end of the slider is connected to the flow guiding plate, and the second end of the slider is connected to a transmission rod.

[0013] As a further improvement, the transmission rod is connected to a transmission assembly at the end away from the guide plate.

[0018] The beneficial effects of this utility model are:

[0019] This invention utilizes a telescopic flow guiding mechanism to facilitate vacuuming operations on smooth vacuum bags. By incorporating this mechanism within the cover cavity, multiple gas channels at the first end of the guide plate effectively guide gas into the lower chamber, optimizing the gas flow path and increasing the gas velocity within the vacuum bag. This avoids the gas path blockage problem caused by overly tight sealing rings in traditional vacuum machines, thus improving vacuuming efficiency. Compared to traditional telescopic flow guiding structures, the protrusion on one side of the lower chamber port prevents the sealing ring near the cover from being compressed by the telescopic flow guiding mechanism, reducing indentations on the two sealing rings. This improves the airtightness of the vacuum chamber during use, preventing external gas from leaking into the vacuum chamber through the indentations on the sealing rings, thus affecting the vacuum pump's performance. It also prevents deformation of the sealing rings due to long-term compression, ensuring the equipment's sealing performance and service life. Attached Figure Description

[0033] Reference Figure 1-2As shown, a vacuum sealing machine with a telescopic guide includes:

[0034] A cover 2 is rotatably mounted on one side of the main body 1; a first panel 11 is mounted on the main body 1, and a cover 12 is mounted on the first panel 11. A cavity is formed inside the cover 12, and a telescopic flow guiding mechanism 3 is installed inside the cavity; a lower chamber 112 is formed on the side of the first panel 11 near the cover 12, and a protrusion 113 is formed on one side of the port of the lower chamber 112 toward the cover 2. Through the protrusion 113 on one side of the port of the lower chamber 112, the two sealing rings can be prevented from directly contacting the telescopic flow guiding mechanism 3 on the side near the cover 12, thereby reducing the compression of the two sealing rings by the telescopic flow guiding mechanism 3, preventing the two sealing rings from deforming due to long-term compression, and ensuring the sealing performance and service life of the equipment.

[0035] Furthermore, referring to Figure 3-4 As shown, a first panel 11 is provided on the main body 1. The first panel 11 is detachably connected to the main body 1. A cover 12 is provided on the first panel 11. A cavity is formed inside the cover 12. A telescopic guide mechanism 3 is provided inside the cavity. A lower chamber 112 is formed on the side of the first panel 11 near the cover 12. A protrusion 113 is formed on one side of the port of the lower chamber 112 towards the cover 2. In this embodiment, the protrusion 113 extends upward along the side wall of the cover 12 at the port of the lower chamber 112, so that a height difference is formed on both sides of the port of the lower chamber 112. An opening 116 is provided on one side of the protrusion 113 in the lower chamber 112. A support plate 117 is provided on the side to separate the two sides of the vacuum bag, facilitating the extension and retraction of the guide plate 35. A control component 5 is also provided inside the cavity, which includes a controller. Multiple buttons 51 are provided on the cover 12, and the buttons 51 are electrically connected to the input end of the controller. The extension and retraction of the telescopic guide mechanism 3 are controlled by the buttons 51. A cutter groove 121 is provided on the cover 12 near the buttons 51, and a cutter assembly 4 is provided in the cutter groove 121. The cutter groove 121 is used for the movement of the cutter assembly 4, which is used to cut the vacuum roll bag, making it convenient for users to cut vacuum bags that are suitable for the size of the sealed items, thus reducing the waste of vacuum bags.

[0036] The first panel 11 has a first sealing ring groove 113 along the edge of the lower chamber 112 and the protrusion 113. The first sealing ring groove 115 is connected to the first sealing ring 13. The main body 1 has a heating component 114 on one side of the lower chamber 112. The first panel 11 has a plurality of locking seats 111. In this embodiment, the locking seats 111 protrude on the first panel 11 near the two sides of the lower chamber 112, which can make the heating component 114 and the pressure strip 22 fit tightly when fastened, and make the upper chamber 212 fit tightly with the lower chamber 112, thereby improving the sealing effect of the vacuum bag. Each locking seat 111 has a limiting groove on one side. The limiting groove is used for the hook 244 on the locking hook component 24 to be inserted into the limiting groove when the locking hook component 24 is in the locked state, so that the cover 2 and the main body 1 are tightly fastened together.

[0037] Furthermore, referring to Figure 5-7 As shown, a second panel 21 is provided on the side of the cover 2 near the first panel 11. The first side of the second panel 21, that is, the side near the first panel 11, forms an upper chamber 212 that matches the lower chamber 112. A recess 213 that matches the protrusion 113 is formed on one side of the port of the upper chamber 212. A second sealing ring groove 214 is provided on the second panel 21 along the edge of the port of the upper chamber 212. The second sealing ring groove 214 is connected to the second sealing ring 23. When fastened, the upper chamber 212 and the lower chamber 112 form a vacuum chamber. The sealing rings of the upper chamber 212 and the lower chamber 112 fit tightly together, improving the airtightness of the vacuum chamber and preventing external gas from entering the vacuum chamber and affecting the sealing effect of the vacuum bag. A pressure strip 22 is provided on the first side of the second panel 21 at the position corresponding to the heating component 114. A groove 215 is provided on the second panel 21 at the position corresponding to the cutter groove 121. The groove 215 is used for the cutter component 4 to be embedded.

[0038] The second side of the second panel 21, i.e., the side away from the first panel 11, has a matching lock groove 211 corresponding to the lock seat 111. Connecting supports are provided on both sides of the lock groove 211. To improve the tightness of the fit between the cover 2 and the main body 1, a lock hook assembly 24 is provided inside the cover 2. The lock hook assembly 24 is correspondingly installed on the connecting supports. The lock hook assembly 24 includes a support 241, a cylinder 242, a push rod 243, a latch 244, and a spring 245. The support 241 is connected to the connecting supports. A connecting post is provided at the end of the support 241 near the cylinder 242. The connecting post is used to limit the movement range of the push rod 243. A movable groove for the push rod 243 to move is formed inside the support 241. Wings are spaced apart on the side of the support 241 near the connecting supports. The wings are adapted to the upper wings, and the wings have openings on the upper... A lower slot is provided to match the upper slot. The upper and lower slots together form a rotating groove. A rotating shaft is provided on both sides of the hook 244. The hook 244 rotates around the rotating groove through the rotating shaft to achieve the engagement and disengagement of the hook 244 with the limiting groove. A push rod 243 is slidably provided in the support 241. The first end of the push rod 243 is connected to the hook 244. The second end of the push rod 243 will abut against the wall of the cylinder 242 when the air is released. A spring 245 is provided between the push rod 243 and the support 241. A cylinder 242 is provided outside the spring 245 and is connected to the support 241. An air hole is provided on the cylinder 241. The air hole is electrically connected to the solenoid valve through a pipeline. In order to improve the stability of the hook 244 when it is connected with the limiting groove, the hook 244 has a stepped hook surface on the side that contacts the limiting groove.

[0039] Furthermore, referring to Figure 8 As shown, the telescopic flow guiding mechanism 3 is provided with a flow guiding plate 35. The flow guiding plate 35 has multiple air guiding channels at its first end. The air guiding channels are used to guide gas into the lower chamber 112. In this embodiment, the air guiding channels are formed by multiple through grooves on the surface of the flow guiding plate 35. Compared with the traditional telescopic air nozzle, this improves the pumping efficiency and the rate of gas extraction from the vacuum bag. The air guiding channels are used to connect the vacuum bag and the vacuum chamber. By embedding the air guiding channels on the flow guiding plate 35, the thickness of the flow guiding plate 35 can be effectively reduced, avoiding deformation of the sealing ring due to the excessive thickness of the flow guiding plate 35 during long-term use, which would affect the sealing effect of the sealing ring.

[0040] A slider 34 is connected to the second end of the guide plate 35. The slider 34 is connected to a transmission rod 33. A transmission assembly 36 is connected to the end of the transmission rod 33 furthest from the slider 34. The transmission assembly 36 includes a driving wheel and a driven wheel. The driven wheel is connected to the transmission rod 33 and is also connected to the driving wheel. The transmission assembly 36 can be a gear transmission or a pulley transmission. A gear transmission assembly can better control the extension and retraction of the guide plate 35. In this embodiment, a gear transmission assembly is preferably provided. The driving wheel and the driven wheel achieve transmission through the meshing of their teeth. The driving wheel is connected to a motor 37, and the motor 37 is connected to the controller. The output terminal is electrically connected. To make the movement of the guide plate 35 more precise, the slider 34 has a sensing part on the side near the controller. The controller is provided with multiple limit switches at the corresponding sensing parts. In this embodiment, the telescopic guide mechanism 3 is configured to switch between a first position, a second position, and a third position. In the third position, the guide plate 35 extends out from the opening 116 under the action of the slider 34, and through the third limit switch on the controller, the guide plate 35 extends into the vacuum bag, so that the opening end of the air guide channel is above the heating component 114, and the vacuum is sealed. When the air pump executes the evacuation command, it guides the gas inside the bag into the vacuum chamber. In the second position, the guide plate 35 retracts from the vacuum bag under the action of the slider 34, and retracts into the vacuum chamber via the second limit switch on the controller. This allows the user to shorten the extension time of the guide plate 37 when sealing items in batches, thus improving sealing efficiency. In the first position, the guide plate 35 is placed inside the chamber via the first limit switch on the controller, protecting the guide plate 35. In this embodiment, the controller is equipped with three sets of limit switches, namely the first limit switch, ... The second limit switch and the third limit switch are located at positions where the guide plate 35 is above the heating assembly 114, the guide plate 35 is above the vacuum chamber, and the guide plate 35 is inside the chamber. Therefore, the preset position of the guide plate 35 can be adjusted according to actual needs. For example, if performing batch food preservation operations, the guide plate 35 can be retracted to the vacuum chamber position to shorten the distance the guide plate 35 moves and improve work efficiency. If cleaning the main body, the guide plate 35 can be retracted into the cover 12.

[0041] The telescopic flow guiding mechanism 3 is also provided with a housing 31 and a sealing shell 38. The sealing shell 38 is located outside the housing 31. A third sealing ring 34 is provided at the connection between the sealing shell 38 and the cover 12. The sealing shell 38 is used to improve the airtightness of the vacuum chamber and prevent gas from leaking into the vacuum chamber from the opening 116. The housing 31 is fixedly connected by bolts or adhesive. Multiple slide rails 32 are provided inside the housing 31. The slider 34 is slidably disposed on the slide rails 32. The slider 34 is used to drive the extension and retraction of the flow guiding plate 35. The first end of the slider 34 is connected to the flow guiding plate 35. In order to reduce the pressure of the flow guiding plate 35 on the first sealing ring 13... Due to the compression of the second sealing ring 23, an abutment post is provided on the slider 34. The abutment post is used to support the guide plate 35 and is fixedly connected by bolts. The abutment post ensures that the height of the guide plate 35 is above the first sealing ring 13 and does not contact the first sealing ring 13. In the closed state, the guide plate 35 is pressed down by the rotation of the cover 2. However, the abutment post controls the downward pressure of the guide plate 35, so that the guide plate 35 only leaves an indentation on the side of the first sealing ring 13 near the heating component 114. As the number of uses increases, the indentation will not deepen. Therefore, the indentation has little impact on the vacuum degree of the vacuum sealing machine.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
