Description

Technical Field

[0001] The invention relates to the technical field of packaging bag processing equipment, in particular to a punching equipment capable of preventing deviation for packaging bag processing. Background Art

[0002] Packaging bags refer to bags used to pack various items, which make it easy to transport and store goods during production and circulation. They are widely used in daily life and industrial production. In the production and processing of packaging bags, it is necessary to punch holes in the packaging bags as needed.

[0003] For example, the prior art CN117021675B proposes a plastic packaging bag punching device, which lays the packaging bag flat and then punches the packaging bag with a punch. This method requires laying the packaging bags one by one, has low processing efficiency and a cumbersome process.

[0004] In response to the defects of the above-mentioned device, the prior art CN118238466B also proposed a punching device with anti-deviation for packaging bag processing. The device uses a winding device to wind up the packaging bag material, and at the same time cooperates with the punching component and the anti-deviation component to realize continuous punching processing of the packaging bag, thereby improving processing efficiency.

[0005] However, although the above device can realize the punching processing of the packaging bag material, when punching, the material is intermittently wound by the winding device to realize the fixed-distance movement of the material. In this way, as the winding progresses, the diameter of the material roll will become larger and larger. Therefore, during intermittent winding, the distance the material moves each time will be inconsistent, resulting in a large error, which will lead to the offset of the punching position. In order to solve the above problem, we provide a punching device with anti-deviation for packaging bag processing to solve the above-mentioned problem. Summary of the invention

When it is necessary to adjust the movement distance of the bag clamping assembly 12, the height of the adjusting block 406 can be adjusted by rotating the threaded rod 410. When the reciprocating bar 407 is raised, the farther the connection point is from the hinge point of the triangular block 408, the longer the lever length is, so the swing amplitude of the triangular block 408 is smaller, thereby making the movement distance of the bag clamping assembly 12 smaller, and vice versa.

When the second equal circular arc 5093 contacts the matching wheel 507, the grooved vertical rod 506 is at the maximum stroke. At this time, the lower end of the grooved vertical rod 506 will touch the first limit switch 15. After the first limit switch 15 is triggered, the first electromagnet 212 is energized to clamp the packaging bag, and then the second electromagnet 126 is de-energized, canceling the clamping of the bag clamping assembly 12 on the packaging bag. At this time The servo motor 18 drives the inflatable shaft 3 to rotate and reel the packaging bag moved by the bag clamping assembly 12, so that the packaging bag maintains appropriate tension. When the torque of the torque sensor 19 exceeds the set value, the servo motor 18 stops to prevent the packaging bag from being torn. Since the reciprocating cam 509 and the downward pressing cam 510 are set at a certain angle, after the second equal arc 5093 contacts the matching wheel 507, the protruding part of the downward pressing cam 510 will immediately touch the pressing wheel 702, driving the pressing wheel 702 to move downward to punch the packaging bag. When the horizontal pressure rod 701 descends, it will touch the third limit switch 17, and then the solenoid valve 906 will open. , release the compressed air, and then use the airflow generated by the compressed air to blow the waste generated by the punching into the collection basket 909 for collection. With the operation of the reciprocating cam 509, the grooved vertical rod 506 will gradually reset by the second reset spring 505 and the reset tension spring 402, and will synchronously drive the bag clamping assembly 12 to reset during the reset. When the grooved vertical rod 506 returns to the initial position, it will touch the second limit switch 16. After the second limit switch 16 is triggered, the second electromagnet 126 is energized to attract the iron core block 124, clamp the protective bag again, and then repeat the above steps to achieve continuous punching of the packaging bag.
