Description

Technical Field

[0001] This utility model relates to the field of vertical rounded corner packaging machines, specifically to a horizontal sealing and stretch packaging machine with a multi-directionally adjustable rounded corner cutter with a tear-off opening. Background Technology

[0002] Existing packaging machines have limitations in the cutting structure and adjustment methods of the horizontal sealing device during the packaging process. For example, the cutter cannot be adjusted in multiple directions, making it difficult to accurately cut packaging materials and form suitable tear edges and rounded corners when dealing with products of different shapes and sizes, thus affecting the aesthetics and ease of use of the packaging.

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a horizontal sealing and stretch packaging machine with a rounded corner cutter with a tear-off that can be adjusted in multiple directions, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A horizontal sealing and stretch packaging machine with a multi-directional adjustable rounded corner cutter with a tear-off edge includes a fixed bracket mounted on a lifting support. A trapezoidal lead screw is arranged parallel to the right side of the fixed bracket. A cutter fixing plate is spirally connected to the outer side of the trapezoidal lead screw. A cylinder is mounted on the outer side of the fixed bracket. A punch is mounted on the output shaft end of the cylinder. A pressure plate is provided on the outer side of the punch. A tear-off cutter is mounted on the end fixing block of the cylinder.

[0007] As a further embodiment of this utility model, the inner side of the fixed bracket is provided with a transverse long groove, and the fixed bracket is slidably connected to the packaging machine.

[0008] As a further embodiment of this utility model, the trapezoidal lead screw is provided with sliding rods on both sides, and the cutter fixing plate slides with the sliding rods on both sides of the trapezoidal lead screw.

[0009] As a further embodiment of this utility model, the inner side of the cutter fixing plate is provided with front and rear long grooves.

[0010] As a further embodiment of this utility model, a corresponding fixed mold is slidably installed on the outer side of the punch.

[0011] As a further embodiment of this utility model, a spring is provided on one side of the pressure plate.

[0012] As a further embodiment of this utility model, a lifter is provided on the outer side of the fixed bracket.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this device, the main body of the cutter is mounted on a lifting bracket. The fixed bracket has a horizontal groove for easy adjustment of the cutter's position left and right on the equipment. Rotating the trapezoidal screw adjusts the cutter's vertical position. The inner side of the cutter fixing plate has front and rear grooves for easy adjustment of the cutter's forward and backward movement. Thus, the cutter can be adjusted in all directions. When the cylinder is ventilated, it drives the punch forward until the pressure plate presses down on the desired cutting position. As it continues forward, the spring compresses, and the tear-off cutter extends to cut the easy-tear opening. When the cylinder retracts, the tear-off cutter first retracts to behind the pressure plate, and then the punch retracts to prevent snagging the bag. This device has adjustment margins in all directions, facilitating equipment debugging. The easy-tear cutter is moved from the general sealing position to the cutting position, allowing the packaging bag to cool before cutting the tear, resulting in a better appearance and a longer tear blade life. Furthermore, the rounded corner mold has a limit, making the tear position more accurate. Attached Figure Description
