Description

Technical Field

[0001] The utility model belongs to the technical field of packaging bag sealing, and particularly relates to a positioning device for packaging bag sealing. Background Art

[0002] Bag sealing refers to the use of specific methods or equipment to close the opening of the bag during the packaging process to ensure the sealing and freshness of the package contents and prevent external contamination. Common sealing methods include heat sealing, electric iron sealing, mechanical equipment sealing, etc. Heat sealing is the most commonly used method. It heats the plastic film of the bag to melt and bond together to form a seal. The positioning device for bag sealing is an auxiliary device, mainly used to ensure accuracy and consistency during the sealing process. It can fix the position of the bag so that the sealing process is carried out in the correct position to avoid deviation or skew, thereby improving the sealing quality and efficiency. The existing positioning device for bag sealing has the disadvantage of limited applicability if the positioning plate size is fixed and cannot be adjusted and expanded.

[0003] For example, the utility model with announcement number CN219215636U discloses a sealing device for packaging bag production. In this patent scheme, the positioning plate of the positioning device for sealing the packaging bag is fixed in size and cannot be adjusted to expand the positioning plate to position and seal packaging bags of different sizes. It is only suitable for packaging bags of specific sizes. For products of different sizes, different positioning devices may need to be replaced, which increases costs and operational complexity. The production line is difficult to quickly adapt to changes in product size, affecting production efficiency and the ability to respond to the market. It is necessary to reserve positioning plates of various sizes to meet different packaging needs, resulting in complex inventory management and increased resource utilization. Utility Model Content

[0004] In view of this, the utility model aims to solve the shortcomings of the prior art and provide a positioning device for sealing packaging bags. The positioning plate can be adjusted and expanded to adapt to packaging bags of various sizes, thereby improving the versatility and flexibility of the equipment. It can also reduce the demand for positioning devices of various sizes and reduce inventory costs and procurement costs.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a positioning device for sealing a packaging bag, comprising a frame, two sliding plates corresponding to positions are slidably arranged on the left and right sides of the frame, electric push rods are arranged on the opposite outer sides of the two sliding plates, positioning plates are arranged on the telescopic ends of the two electric push rods, and positioning adjustment mechanisms are arranged inside the two positioning plates. Height adjustment mechanisms are arranged on the left and right sides of the frame, the positioning adjustment mechanism comprises four expansion plates slidably arranged on the front and rear sides of the two positioning plates, rotating seats are arranged on the outer sides of the four expansion plates, connecting frames are arranged inside the four rotating seats, slide groove plates are arranged on the upper ends of the two positioning plates, rotating frames are slidably arranged inside the two slide groove plates, the upper ends of the two connecting frames are respectively rotatably connected to the inside of a rotating frame, and electric drive units 1 for driving the rotating frame to move are arranged on the outer sides of the two positioning plates, and the electric drive unit 1 comprises electric push rods 2 respectively arranged on the outer sides of the two positioning plates, and the telescopic ends of the two electric push rods 2 are respectively connected to the lower ends of adjacent rotating frames.

[0006] As a further improvement of the present invention, two mounting blocks are respectively arranged on the front and rear sides of the frame, and mounting holes are provided inside the four mounting blocks.

[0007] As a further improvement of the utility model, the height adjustment mechanism includes connecting plates respectively arranged on the left and right sides of the frame, and screw rods are rotatably arranged inside the two connecting plates. The two sliding plates are respectively threadedly connected to adjacent screw rods, and the upper ends of the two connecting plates are respectively provided with electric drive units 2 for driving the screw rods to rotate. The electric drive unit 2 includes motors respectively arranged on the upper ends of the two connecting plates, and the output shafts of the two motors are respectively connected to the upper ends of adjacent screw rods through couplings.

[0008] As a further improvement of the utility model, a control panel is arranged on the front side of the frame, and the motor, the first electric push rod and the second electric push rod are all electrically connected to the control panel.

[0009] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0010] First, the packaging bag that needs to be sealed and positioned is transported between the two positioning plates through an external conveying mechanism, and then the electric push rod is controlled to open and run, and the telescopic end drives the positioning plates and expansion plates on both sides to move closer, so that the packaging bag can be quickly positioned.

[0011] Secondly, by controlling the opening of the second electric push rod, the telescopic end drives the rotating frames on both sides to move downward under the restriction of the slide plate, so that the internal connecting frame rotates and expands, and then the expansion plates on the rotating seats on both sides move away from each other, thereby realizing the expansion adjustment of the positioning plate positioning size to adapt to the sealing positioning of packaging bags of different sizes. The positioning plate can be adjusted and expanded to adapt to packaging bags of various sizes, thereby improving the versatility and flexibility of the equipment, and can also reduce the demand for positioning devices of various sizes, thereby reducing inventory costs and procurement costs.

[0012] Thirdly, by controlling and turning on the two motors, the output shaft drives the screw rod to rotate, so that the positioning plate on the sliding plate can be moved, and then the positioning height of the positioning plate can be adjusted, thereby improving the flexibility of the positioning device.

[0013] Fourthly, the positioning device can be quickly installed through the mounting holes on the mounting block, making it convenient for personnel to install the positioning device on the sealing machine. BRIEF DESCRIPTION OF THE DRAWINGS
