Description

Technical Field

[0001] This utility model relates to the field of three-side sealing bag making machine technology, and more specifically, to a punching device for a three-side sealing bag making machine. Background Technology

[0002] Three-side sealing bag making machine is a highly automated bag making equipment, mainly used to make flat or tubular plastic bags. Through processes such as heating, pressurizing, and cooling, the plastic film is heat-sealed at the three sides to form the required plastic bag. Small holes are punched in the packaging bags processed by the three-side sealing bag making machine to allow for ventilation or heat dissipation.

[0003] A search revealed that utility model patent CN219727393U discloses a punching device for a three-side sealing bag making machine, including a gantry frame. A lifting block is located inside the gantry frame. Two cylinders are fixedly inserted into the top inner part of the gantry frame. The lower ends of the cylinders are fixedly connected to the upper ends of the lifting block. Multiple movable blocks are slidably sleeved on the lifting block. A push rod is slidably inserted into the lower end of each movable block. A punch is fixedly connected to the lower end of the push rod. The upper end of the push rod slidably passes through the movable block and is fixedly connected to a connecting block. Two second guide rods are slidably inserted into the upper end of the connecting block. The lower ends of the second guide rods pass through the connecting block and are fixedly connected to the upper end of the movable block. A first driving mechanism is located at the lower end of the connecting block. A guiding mechanism is located on the inner side of the movable block. This patent, through the setting of multiple driving mechanisms, automatically adjusts the number of punches needed and automatically adjusts the position of the punches. Compared with manual adjustment, it has higher efficiency and accuracy, and is more practical. The above-mentioned patent also has the following shortcomings: Although the number and position of multiple punches can be adjusted, multiple punches are located on the same straight line. When it is necessary to process ventilation holes that are not located on a straight line on the packaging bag, repeated punching is required, which is not convenient to use. Moreover, waste is generated during the punching process, which is not easy to clean. Therefore, we have proposed a punching device for a three-side sealing bag making machine. Utility Model Content

The side of the gantry frame 1 is provided with a chip suction mechanism 2.

[0026] In this embodiment, the top of the punch 13 is provided with a threaded post so that the punch 13 can be installed on the internal thread seat 12, while ensuring that the punch 13 can be replaced. In addition, the height of the internal thread seat 12 and the punch 13 can be adjusted by the electric telescopic rod 11, so that one or more punches 13 can be moved to a higher position so that the punch 13 does not perform drilling operation.

[0027] For details, please refer to Figure 1 and Figure 5 The chip collection mechanism 2 includes a chip collection box 15 fixedly connected to the side of the gantry frame 1. A filter screen 16 is fixedly sleeved in the inner cavity of the chip collection box 15. An air pump 17 is fixedly installed on the back of the chip collection box 15. The input end of the air pump 17 extends into the inner cavity of the chip collection box 15. A chip collection pipe 18 is fixedly sleeved on the side of the chip collection box 15. A chip collection cover 19 is fixedly connected to the end of the chip collection pipe 18. The end of the chip collection cover 19 is fixedly sleeved to the inner side of the gantry frame 1.

[0028] For details, please refer to Figures 1 to 5 A control panel 21 is fixedly installed on the side of the gantry frame 1. The control panel 21 is electrically connected to the cylinder 3, the first brake motor 6, the electric telescopic rod 11, the second brake motor 14, and the air pump 17.

[0029] In this embodiment, the control panel 21 is used to control the cylinder 3, the first brake motor 6, the electric telescopic rod 11, the second brake motor 14, and the vacuum pump 17. In addition, the power supply of the external device is used to supply power to the control panel 21, the cylinder 3, the first brake motor 6, the electric telescopic rod 11, the second brake motor 14, and the vacuum pump 17.

[0030] For details, please refer to Figures 2 to 4 The top surface of the transverse block 7 is in contact with the top surface of the inner cavity of the transverse box 4.

[0031] In this embodiment, the top surface of the inner cavity of the transverse box 4 is used to limit the transverse block 7, so that the transverse block 7 can only move along the axial direction of the first screw 5.

[0032] For details, please refer to Figure 4 The side of the movable block 10 fits against the inner wall of the movable box 8.

[0033] In this embodiment, the inner wall of the movable box 8 is used to limit the movable block 10, so that the movable block 10 can only move along the axial direction of the second screw 9.

[0035] In this embodiment, the waste chips collected inside the chip storage box 15 are removed by opening the sealing door 20.

[0036] Working principle: In use, first determine how many punches are needed to punch holes in the plastic bag. Use the electric telescopic rod 11 to move the unused punches 13 upwards. Then, start multiple first brake motors 6 to rotate multiple first screws 5. Through the threaded engagement between the first screws 5 and the transverse block 7, the transverse block 7, the moving box 8, and the punches 13 move laterally, thus adjusting the lateral position of the punches 13. Next, start the second brake motor 14 to rotate the second screw 9. Through the threaded engagement between the second screw 9 and the moving block 10, the moving block 10, the electric telescopic rod 11, and... The punch 13 moves back and forth to adjust its punching position. Finally, when the plastic bag moves below the gantry 1, the cylinder 3 drives the horizontal box 4 and the punch 13 to move up and down, punching holes in the plastic bag. At the same time, the vacuum pump 17 is started to draw air from the inner cavity of the chip collection box 15. The negative pressure in the inner cavity of the chip collection box 15 causes the chip suction pipe 18 and the chip suction hood 19 to generate suction. The suction of the chip suction hood 19 sucks the waste chips generated by punching into the inner cavity of the chip collection box 15, and the filter screen 16 traps the waste chips in the inner cavity of the chip collection box 15 for collection.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
