DETAILED DESCRIPTION

[0019] The utility model is now described in further detail with reference to the accompanying drawings. The accompanying drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] A corrugated paper hole punching device, comprising a base 1, a sliding seat 2, a pushing assembly 3 and a hole puncher 5, wherein a support plate 11 is horizontally fixedly arranged above the bottom plate of the base 1 by setting a plurality of legs 13, and screw assemblies 14 are fixedly arranged on the vertical surfaces of both sides of the support plate 11, and two sliding seats 2 are respectively mounted on two screw assemblies 14, and the pushing assemblies 3 used for pushing corrugated paper are respectively slidably installed on the vertical surfaces facing each other of the two sliding seats 2, and the two screw assemblies 14 operate synchronously to drive the two sliding seats 2 to move in a certain direction. The supporting plate 11 slides back and forth synchronously along the feeding direction. The supporting plate 11 is divided into a feeding side and a hole opening side along the processing order of the corrugated paper. A gantry 12 is arranged above the hole opening side of the supporting plate 11. The hole opener 5 is vertically suspended under the gantry 12 through a hydraulic seat 17. The corrugated paper is placed on the feeding side of the supporting plate 11. The sliding seat 2 and the pushing assembly 3 slide in coordination to push the corrugated paper from the feeding side to the hole opening side. The hydraulic seat 17 extends downward, that is, the corrugated paper is subjected to hole opening processing through the hole opener 5.

[0021] The hole opener 5 includes a hole opening cutting tube 51 and a high-pressure gas nozzle 52. The high-pressure gas nozzle 52 is fixedly mounted on the telescopic end face of the hydraulic seat 17 pointing downward. The outer circumferential surface of the high-pressure gas nozzle 52 is processed with an external thread. The upper end of the hole opening cutting tube 51 is threadedly installed on the high-pressure gas nozzle 52. The lower edge of the hole opening cutting tube 51 is processed into a cutting blade. A collecting bin is arranged below the hole opening side of the support plate 11. A discharge port that passes through from top to bottom is arranged at the hole opening side of the support plate 11 and the hole opening device 5. The residual material produced by the hole opening and cutting of the hole opener 5 enters the collecting bin through the discharge port. The high-pressure gas nozzle 52 is ventilatedly connected to the air pump. The operation of the air pump causes the high-pressure gas nozzle 52 to spray out a high-pressure airflow. When the hole opening cutting tube 51 is used to cut a hole in corrugated paper, the corrugated paper residual material embedded in the hole opening cutting tube 51 is blown out of the hole opening cutting tube 51 by the high-pressure airflow sprayed by the high-pressure gas nozzle 52.

[0022] A hydraulic seat 15 is vertically arranged in the collecting bin, and the hydraulic seat 15 is vertically aligned with the discharge port. The telescopic end of the top of the hydraulic seat 15 is coaxially fixed with a support bracket 16 to prevent the corrugated paper from being deformed. When the corrugated paper is cut and punched, the hydraulic seat 15 is extended upward to make the upper end surface of the support bracket 16 flush with the upper end surface of the supporting plate 11 to prevent the corrugated paper from being deformed during processing and causing inaccurate hole processing position. When the hole processing is completed, the hydraulic seat 15 is shortened downward, the support bracket 16 moves down, and the high-pressure airflow ejected from the high-pressure air nozzle 52 blows the residual material in the hole cutting tube 51 into the collecting bin.

[0023] The pushing assembly 3 includes a pushing seat 31, a hydraulic rod 2 32 and a push plate 33. A screw assembly 21 is arranged on the inner facade of the sliding seat 2 away from the gantry 12. The screw assembly 21 is arranged in the horizontal direction and is located in the middle of the sliding seat 2 in the vertical direction. The pushing seat 31 is arranged on the screw assembly 21. The hydraulic rod 2 32 is arranged on the pushing seat 31. The telescopic end of the hydraulic rod 2 32 is fixedly arranged with a push plate 33. The push plate 33 is bent at a right angle and arranged vertically. The two push plates 33 on the two pushing assemblies 3 are arranged facing each other. The two hydraulic rods 2 32 are extended and shortened synchronously, that is, the distance between the two push plates 33 is adjusted to adapt to the size of the corrugated paper.

[0024] A fixed seat 23 is protrudingly arranged on the inner facade of the sliding seat 2 near one end of the gantry 12, a hydraulic rod 24 is arranged in the fixed seat 23, an end plate 25 is fixedly arranged at the telescopic end of the hydraulic rod 24, a limit plate 4 is hingedly installed on the side edge of the end plate 25 near the gantry 12, the limit plate 4 is driven by a stepping motor embedded in the end plate 25 to rotate on the end plate 25, and the limit plate 4 and the end plate 25 can be bent at a right angle or flattened at a flat angle;

[0025] When pushing corrugated paper, the limit plate 4 and the end plate 25 are bent at a right angle, and the hydraulic rod 1 24 and the hydraulic rod 2 32 are adjusted in coordination to adjust the two pairs of limit plates 4 and the end plates 25 and the two push plates 33 respectively located on the two sliding seats 2, and the space is coordinated with the size of the corrugated paper to form a rectangular space for pushing the corrugated paper. When the sliding seat 2 moves to push the corrugated paper, one side end face of the limit plate 4 is against the transported corrugated paper for limiting, and the other side end face of the limit plate 4 pushes the corrugated paper that has completed the punching process to enter the next processing step. After the corrugated paper is pushed, the hydraulic rod 1 24 and the hydraulic rod 2 32 are adjusted in coordination to shorten, and the limit plate 4 is adjusted to rotate, so that the limit plate 4 and the end plate 25 are in a flattened state, and the sliding seat 2 is adjusted to slide back to the feeding side of the supporting plate 11.

[0026] A plurality of feeding rollers 18 are arranged on the upper surface of the opening side of the supporting plate 11 to reduce friction and ensure that the corrugated paper can be quickly pushed to the desired position.

[0027] A guide strip 22 is provided on the inner facade of the sliding seat 2 at a position aligned with the upper and lower positions of the screw assembly 21 to ensure that the pushing seat 31 can slide smoothly under the drive of the screw assembly 21. The two screw assemblies 14 are driven synchronously, and the two screw assemblies 21 are driven synchronously.

[0028] Working principle:

[0029] Place a single or multiple sheets of corrugated paper on the feeding side of the supporting plate 11, and the placement height of the corrugated paper does not exceed the length of the hole cutting tube 51, so that the limit plate 4 and the end plate 25 are bent at a right angle, and the hydraulic rod 1 24, the hydraulic rod 2 32 and the screw assembly 2 21 are coordinated and regulated to operate, and the position of the corrugated paper is adjusted by the end plate 25, the limit plate 4 and the push plate 33, and then the screw assembly 1 14 is regulated to operate to make the sliding seat 2 slide to complete the pushing of the corrugated paper, and when the corrugated paper is pushed to the required position, the hydraulic seat 1 15 is regulated to extend, so that the support 16 is against the bottom layer of corrugated paper, and then the hydraulic seat 2 17 is regulated to extend, so that the hole opener 5 performs hole opening processing on the corrugated paper. During the hole opening processing, the sliding seat 2 is packed and stable, and after the punching processing is completed, the hydraulic seat 2 17 retracts and the high-pressure air nozzle 52 sprays high-pressure airflow to remove the residual material in the hole cutting tube 51.

[0030] In the device, the hydraulic seat 2 17, the hole opener 5, the hydraulic seat 1 15, the support bracket 16 and the number and position of the discharge ports can be set according to specific processing requirements. The hole opening and pipe cutting 51 is installed by threading, and can be quickly replaced after the sharpness of the working blade decreases, thereby ensuring the processing quality.
