Problems solved by technology

[0002] Most of the existing ultrasonic sealing machines are vertical sealing machines, which generally include a welding head extending in the vertical direction, an ultrasonic transducer connected to the welding head, and a horizontally arranged workbench. The workbench is placed under the welding head. There is an L-shaped groove corresponding to the welding head. When working, it is necessary to stick the opening of the packaging bag in the groove and pre-tighten it to prevent deviation. However, this sealing method is only suitable for folding at the opening of the packaging bag. Vertical welding is still inconvenient to use, especially when used in supermarkets, this inconvenience is more obvious. In addition, the existing ultrasonic sealing machine has a single function and often only has the edge sealing function. After the edge sealing is completed, it needs to be sealed. The packaging bag is placed on the corresponding weighing table for product weighing, which is inefficient

Embodiment 1

[0057] like Figure 4 As shown, the weighing unit 30 is elongated and extends in a horizontal first direction, one end of which is fixed on the rack 10 , and the other end is fixed on the bottom plate 2113 of the fixing frame 21 . In this embodiment, the weighing unit 30 can support the weight of the ultrasonic sealing unit 20 and its attachments, the structure of the ultrasonic sealing unit 20 is more stable, and the structure is simple and practical.

Embodiment 2

[0059] like Figure 5 As shown, the rack 10 is provided with a first wall 11 extending along the first direction and perpendicular to the first sealing surface 2211, the first wall 11 is parallel and opposite to the second wall 2111 of the body 211 of the fixing frame 21; the weighing unit 30 is a long strip, which is installed between the first wall 11 and the second wall 2111 , one end of which is fixed to the first wall 11 , and the other end is fixed to the second wall 2111 . In this embodiment, the ultrasonic sealing unit 20 can apply an elastic deformation force to the weighing unit 30 without occupying the space below the ultrasonic sealing unit 20, and the structure is simple and practical.

Embodiment 3

[0061] like Image 6As shown, the weighing unit 30 is elongated and extends along the first direction. One end of the weighing unit 30 is fixed to one end of the rack 10 away from the interval, and the other end is fixed to the end of the fixing frame 21 away from the interval. Specifically, one end of the weighing unit 30 is fixedly connected to the third wall 2112 , and the other end is fixedly connected to a wall of the rack 10 that is parallel and opposite to the third wall 2112 . In this embodiment, the ultrasonic sealing unit 20 can apply an elastic deformation force to the weighing unit 30 without occupying the space below the ultrasonic sealing unit 20, and the structure is simple and practical.

[0062] The working process is as follows:

[0063] In the initial state, the first sealing surface 2211 and the second sealing surface 231 are away from each other and the space between them is open in the second direction. The sealing member, that is, the opening of the sp...

Abstract

The invention discloses an intelligent weighing and sealing all-in-one machine which is used for sealing and weighing a to-be-sealed part in a vertical state and comprises a rack, an ultrasonic sealing unit, a weighing unit and a display unit. The ultrasonic sealing unit comprises a fixing frame, an ultrasonic generator, a sealing anvil and a driving part, the ultrasonic generator is provided with a first sealing face, and the sealing anvil is provided with a second sealing face parallel and opposite to the first sealing face; the driving part is used for driving the ultrasonic generator or the sealing anvil to slide relative to the fixing frame; when the first sealing surface is far away from the second sealing surface, the gap between the first sealing surface and the second sealing surface is at least opened along one lateral direction; the weighing unit is used for at least bearing and measuring the weight of the to-be-sealed part when the first sealing surface is close to the second sealing surface; the display unit is used for displaying the weight of the to-be-sealed part. The technical scheme is suitable for being used in supermarkets, commodities can be weighed while sealing is conducted, and the sealing machine is convenient to use, high in efficiency and good in stability.

Description

technical field [0001] The invention relates to the technical field of edge sealing, in particular to an intelligent weighing and sealing integrated machine. Background technique [0002] Most of the existing ultrasonic sealing machines are vertical sealing machines, which generally include a welding head extending in the vertical direction, an ultrasonic transducer connected to the welding head, and a horizontally arranged workbench. The workbench is placed under the welding head. There is an L-shaped groove corresponding to the welding head. When working, the opening of the packaging bag needs to be attached to the groove and pre-compressed to prevent deviation, but this sealing method is only suitable for folding at the opening of the packaging bag. Vertical welding is still relatively inconvenient to use, especially when used in supermarkets, the inconvenience is more obvious. In addition, the existing ultrasonic sealing machine has a relatively simple function, and ofte...
