Description

Technical Field

[0001] This utility model relates to a vacuum sealing machine with a rotary external extraction switch. Background Technology

[0002] A vacuum sealing machine is a device used to achieve vacuum packaging. It creates a vacuum inside the packaging bag by removing the air, thereby extending the shelf life of food, medicine and other items and maintaining their freshness.

[0003] Existing vacuum sealing machines are divided into external extraction type and internal extraction type. The external extraction function of vacuum sealing machines is specifically designed for sealing large, hard or irregularly shaped items that cannot be placed in traditional chamber-type vacuum machines. Existing vacuum sealing machines do not combine external extraction and internal extraction, which limits their application scenarios. Therefore, this utility model addresses the above problems by designing a vacuum sealing machine with a rotary external extraction switch. Utility Model Content

[0004] This invention provides a vacuum sealing machine with a rotary external extraction switch, which can effectively solve the above problems.

[0005] This utility model is implemented as follows:

[0006] A vacuum sealing machine with a rotary external draw switch, comprising:

[0007] The sealing machine body has a built-in sealing cavity;

[0008] The vacuum sealing unit, located inside the sealing machine body, includes a control board and a vacuum pump group electrically connected to the control board. The vacuum pump group is connected to the air guide hole to evacuate the sealing body.

[0009] The external extraction device, located inside the sealing machine, is used to connect the item to be vacuumed for external extraction when the vacuum pump unit is started.

[0010] As a further improvement, the external extraction device includes a hollow rotary joint and a connecting fastener connecting the rotary joint and the sealing cavity. The rotary joint includes a rotating part and a first tube integrally formed with the rotating part. An opening groove is provided on the side wall of the end of the first tube. The connecting fastener includes a socket cylinder that can receive the rotating first tube and a second tube integrally formed with the socket cylinder. When the vacuum sealing unit is evacuating, the rotary joint is rotated so that the opening groove connects to the second tube. The rotary joint is connected to the item to be evacuated for external extraction.

[0011] As a further improvement, the vacuum sealing unit also includes a drive button that is electrically connected to the vacuum pump group. The drive button is located inside the sealing machine body. The external extraction device also includes a rotating disk that is sleeved on the first tube column and rotates synchronously with the rotary joint. A toggle block is provided on the side wall of the rotating disk. Rotating the rotary joint causes the opening slot to connect with the second tube column, and the toggle block presses against the drive button.

[0012] As a further improvement, a mounting hole is provided on the side wall of the sealing machine body, the rotary joint is disposed in the mounting hole, and a mounting groove corresponding to the rotating disk is provided on the inner bottom wall of the sealing machine body, the rotating disk is disposed in the placement groove.

[0013] As a further improvement, it further includes a sealing machine cover hinged to the sealing machine body, wherein the sealing machine cover is provided with a fastening cavity corresponding to the sealing chamber, the item to be vacuumed is placed in the sealing chamber, and the sealing machine body and the sealing machine cover are fastened together to vacuum the item to be vacuumed.

[0014] As a further improvement, a heat sealing device is provided inside the sealing machine body and the sealing machine cover. The heat sealing device includes a heat sealing knife located in front of the sealing cavity and a receiving groove located in front of the fastening cavity.

[0015] As a further improvement, a collection device is also provided on the bottom wall of the sealing machine body. The collection device includes an installation groove on the sealing machine body, and a detachable collection water tank is provided in the installation groove. The collection water tank includes a first through hole provided on the upper side wall of the collection water tank, and a second through hole provided on the side of the first through hole. The first through hole is connected to the vacuum pump group, and the second through hole is connected to the air guide hole.

[0016] As a further improvement, a first connector is provided on the first through hole, and a second connector is provided on the second through hole. The first connector is connected to the vacuum pump group through a conduit, and the second connector is connected to the gas guide hole through a conduit.

[0017] The beneficial effects of this utility model are:

[0018] (1) The sealing machine body has a built-in sealing chamber, and the bottom of the sealing chamber is provided with an air guide hole; the sealing machine body is provided with a vacuum sealing unit, which includes a control board and a vacuum pump group electrically connected to the control board. The vacuum pump group connects to the air guide hole to evacuate the sealing chamber. The present invention is also provided with an external evacuation device, including a hollow rotary joint and a connecting fixing part connecting the rotary joint and the sealing chamber. The rotary joint includes a rotating part and a first tube column integrally formed with the rotating part. An opening groove is provided on the side wall of the end of the first tube column. The connecting fixing part includes a socket cylinder that can be inserted into the rotating first tube column and a second tube column integrally formed with the socket cylinder. When the vacuum sealing unit is controlled to evacuate, the rotary joint is rotated so that the opening groove connects to the second tube column. The rotary joint connects to the item to be evacuated for external evacuation. The present invention adds an external evacuation function to the original internal evacuation vacuum sealing machine. The external evacuation function can be opened by simply rotating the rotary joint, which is convenient for evacuating large, hard or irregularly shaped items that cannot be put into a traditional chamber vacuum machine. It can handle small, regular items as well as large, hard items, overcoming the limitations of single-function internal vacuum sealing machines.

[0019] (2) When the rotary joint rotates, the opening groove of the first tube column is aligned with the second tube column. At the same time, the toggle block presses the drive button, which triggers the vacuum pump to start synchronously. The user only needs to rotate the external pumping interface to open the gas passage and start the vacuum pump at the same time. It is easy to operate and does not require additional solenoid valves or sensors. The pure mechanical structure reduces the failure rate and production cost. Attached Figure Description
