Description

Technical Field

[0001] The utility model relates to packaging equipment, in particular to a cutting mechanism of an ice bag machine. Background Art

[0002] An ice bag machine is a device used to realize the automatic feeding and packaging of ice bags. After the ice bags are filled and heat-sealed, a cutting mechanism is required to cut the packaging substrate to obtain individual ice bags. Currently, for the cutting mechanism of ice bag machines on the market, the cross-cutting component usually adopts a structure in which a cylinder drives a cutter to act for cutting. The defect of this structure is that in order to ensure stable cutting, the air consumption required by the cylinder is very large, resulting in high energy consumption during equipment production and failing to meet the requirements of energy-saving production. In addition, this cross-cutting component is generally fixed on the machine frame, making it difficult to adjust its position. When the cutting position changes, it can only be adjusted by adjusting the traction component or other components, resulting in very inconvenient adjustment operations and poor adjustment flexibility. Summary of the Utility Model

[0003] In view of the deficiencies of the background art, the technical problem to be solved by the present utility model is to provide a cutting mechanism of an ice bag machine for solving the above problems.

[0004] To this end, the present utility model is implemented as follows:

[0005] A cutting mechanism of an ice bag machine includes a vertical cutting component and a cross-cutting component. The vertical cutting component includes cutting wheels arranged on a cutter shaft, and a vertical cutter is provided corresponding to each cutting wheel. The cross-cutting component includes an upper cutter provided on a cutter seat, a lower cutter is provided in cooperation with the upper cutter below, the lower cutter is arranged on a moving frame, the cutter seat is connected to a lifting seat through a guide post, the guide post passes through a guide sleeve fixed on the moving frame, and a first motor is further included on the moving frame. The output end of the first motor is connected to a rotating disk, the rotating disk is eccentrically hinged to one end of a transmission arm, and the other end of the transmission arm is hinged to the lifting seat. The moving frame is slidably arranged on the machine frame and is connected to a moving adjustment component.

[0006] The moving adjustment component includes an adjustment screw rod rotatably arranged on the machine frame, and the adjustment screw rod is screwed with the moving frame.

[0007] A second motor is further included, the output end of the second motor is connected to a first synchronous pulley, a synchronous belt is wound around the first synchronous pulley, the synchronous belt bypasses a second synchronous pulley, and the second synchronous pulley is connected to the cutter shaft.

[0008] A material supporting plate is arranged between adjacent cutting wheels.

[0009] A bag pressing frame is provided at the feeding end corresponding to the cross-cutting assembly, and the bag pressing frame is installed on the moving frame.

[0010] For a cutting mechanism of an ice bag machine with the above technical solution, by adopting a motor-driven eccentric wheel transmission mechanism to drive the cutter holder to lift, the upper and lower cutters are further coordinated to perform cross-cutting operations, replacing the traditional method of driving the upper cutter to lift by a cylinder, achieving zero air consumption cutting, and when using a motor drive, the power consumption required is less than that of an air pump, enabling energy-saving production; in addition, the improved cross-cutting assembly is arranged on the moving frame. When the ice bag specification changes and the cutting position changes, the position of the cross-cutting assembly can be adjusted by controlling the movement of the moving frame and cooperating with the traction assembly, making the adjustment operation of the cutting position more flexible and convenient.

[0017] As shown in the figure, a cutting mechanism of an ice bag machine disclosed by the present utility model includes a vertical cutting component and a horizontal cutting component. The vertical cutting component includes cutting wheels 2 arranged on a cutter shaft 7, and a vertical cutter 1 is provided corresponding to each cutting wheel 2. The horizontal cutting component includes an upper cutter 12 arranged on a cutter seat 13, and a lower cutter 11 is arranged in cooperation below the upper cutter 12. The lower cutter 11 is arranged on a moving frame 14. The cutter seat 13 is connected to a lifting seat 9 through a guide post 10. The guide post 10 passes through a guide sleeve 18 fixed on the moving frame 14. It also includes a first motor 15 arranged on the moving frame 14. The output end of the first motor 15 is connected to a rotating disk 17. One end of a transmission arm 8 is eccentrically hinged to the rotating disk 17, and the other end of the transmission arm 8 is hinged to the lifting seat 9. The moving frame 14 is slidably arranged on the machine frame and is connected to a moving adjustment component. Specifically, the moving adjustment component includes an adjustment screw 21 rotatably arranged on the machine frame, and the adjustment screw 21 is screwed to the moving frame 14. In addition, it also includes a second motor 6. The output end of the second motor 6 is connected to a first synchronous pulley 5. A synchronous belt 4 is wound around the first synchronous pulley 5. The synchronous belt 4 bypasses a second synchronous pulley 3, and the second synchronous pulley 3 is connected to the cutter shaft 7. A material supporting plate 19 is arranged between adjacent cutting wheels 2, which can support the conveyed ice bags and prevent the ice bags from falling due to excessive weight during the traction conveying process. A bag pressing frame 20 is arranged at the feeding end of the horizontal cutting component. The bag pressing frame 20 is installed on the moving frame 14. By arranging the bag pressing frame 20, the passing ice bags can be limited to ensure the flatness of the ice bags.

[0018] The working principle of the present utility model is as follows: The ice bags completed with loading and heat sealing first pass through the vertical cutting component. The cutting wheels 2 and the vertical cutters 1 cooperate to perform vertical cutting on the ice bags. Then, they are sent to the horizontal cutting component. The first motor 15 drives the rotating disk 17 to rotate, and then drives through the transmission arm 8 to drive the lifting seat 9 to lift along the axial direction of the guide post 10, thereby synchronously driving the cutter seat 13 and the upper cutter 12 to lift, and cooperating with the lower cutter 11 to perform horizontal cutting on the ice bags to obtain single ice bags. In addition, by controlling the rotation of the adjustment screw 21, the moving frame 14 can be driven to move horizontally, thereby adjusting the overall position of the horizontal cutting component to meet the use requirements of horizontal cutting at different positions.

[0019] With this structure of the present utility model, by adopting a motor-driven eccentric wheel transmission mechanism to drive the cutter seat to lift, thereby realizing the cooperation of the upper and lower cutters to perform horizontal cutting operations, replacing the traditional method of driving the upper cutter to lift by a cylinder, achieving zero-air-consumption cutting, and when using a motor drive, the power consumption required is less than that of an air pump, enabling energy-saving production; in addition, the improved horizontal cutting component is arranged on the moving frame. When the ice bag specifications change and the cutting position changes, the position of the horizontal cutting component can be adjusted by controlling the movement of the moving frame and cooperating with the traction component, making the adjustment operation of the cutting position more flexible and convenient.
