Technical Field

[0001] The utility model relates to the technical field of packaging box production, in particular to a waste material discharging device of a punching device used in the production of paper packaging boxes. Background Art

[0002] Paper packaging boxes are the most widely used packaging products. Depending on the materials used, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. During the processing and production of paper packaging boxes, the cardboard needs to be cut according to different sizes and specifications. Paper packaging boxes are now commonly used in transportation. The surface of the packaging box will have holes such as ventilation holes, carrying handle holes, and decorative holes according to the use effect.

[0003] Since some packaging boxes only need to be perforated on one side, punching the cardboard after bending it can easily damage the paper surface that does not need to be processed, and the downward pressure of the punching device can easily cause the corrugated paper to be damaged. Therefore, a punching device is required to effectively protect the paper surface that does not need to be punched, and at the same time facilitate the rapid discharge of waste generated by punching.

Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are intended solely to refer to the directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0025] like Figure 1-5 The waste material discharge device of the punching device for producing paper packaging boxes shown in the figure includes a support assembly 1 and a mounting mechanism 2. The mounting mechanism 2 is arranged on the top of the support assembly 1. The support assembly 1 includes a bottom plate 11, a support bar 12, a guide device 13, a lifting seat 14, a clamping ring 15 and an air outlet 16. The support bar 12 is fixedly arranged on the upper surface of the bottom plate 11, the guide device 13 is fixedly arranged at both ends of the bottom plate 11, the lifting seat 14 is clamped on the inner side of the guide device 13, the clamping ring 15 is fixedly arranged on the inner side of the lifting seat 14, and the air outlet 16 is clamped inside the lifting seat 14. The mounting mechanism 2 includes a lining seat 21, a support bar 22, a stamped support plate 23, a reinforcement ring 24, a connecting seat 25 and a support knob 26. A mounting groove cooperating with the stamped support plate 23 is provided on the top of the lining seat 21. The stamped support plate 23 and the lining seat 21 are fixed by screws. The support bar 22 is arranged inside the lining seat 21 and is located outside on both sides of the mounting groove at the top of the lining seat 21. The reinforcement ring 24 is fixedly arranged at the bottom of the stamped support plate 23. The connecting seat 25 is fixedly arranged at the bottom of the reinforcement ring 24. The support knob 26 is connected to the bottom of the connecting seat 25 by threads.

[0026] Specifically, the guide device 13 includes a guide seat 131, a guide rod 132 and a spring 133. The guide seat 131 is fixed to the upper surface of the base plate 11, the guide rod 132 is vertically fixed to the inner side of the guide seat 131, and the spring 133 is sleeved on the outer side of the guide rod 132. The two ends of the lifting seat 14 are clamped inside the guide seat 131, and the two ends of the lifting seat 14 are provided with clamping holes that cooperate with the guide rod 132. The spring 133 is located between the bottom of the lifting seat 14 and the inner side of the bottom of the guide seat 131. A stamping hole is opened on the surface of the stamping support plate 23, and the reinforcement ring 24 is located on the outer edge of the stamping hole on the surface of the stamping support plate 23. The reinforcement ring 24 is located on the side away from the clamping ring 15 and is in an open form. One end of the lining seat 21 is clamped inside the clamping ring 15, and one end of the air outlet nozzle 16 passes through and extends to the inside of one end of the lining seat 21. The bottom of the support knob 26 contacts the inner side of the bottom of the lining seat 21.

[0027] In this embodiment, a matching stamping support plate 23 is first selected according to the punching tool and the punching position required on the surface of the paper packaging box. A stamping hole that meets the hole opening on the surface of the paper packaging box is opened on the surface of the stamping support plate 23, which is located on the outside of the bottom of the stamping hole. A reinforcement ring 24 is provided at the bottom of the stamping support plate 23, and a support knob 26 is rotated at the bottom of the connecting seat 25 at the bottom of the reinforcement ring 24, so that after the stamping support plate 23 is installed, the bottom of the support knob 26 contacts the inner side of the bottom of the lining seat 21, thereby increasing the edge strength of the stamping hole during the stamping process, so that the edge of the stamping hole on the surface of the stamping support plate 23 will not collapse and deform when the punching hole is subjected to pressure from the equipment and the tool. A support bar 22 is provided inside the lining seat 21 to improve the pressure resistance of the lining seat 21 while guiding the discharge of waste.

[0028] Furthermore, one end of the lining seat 21 is clamped into the inside of the clamping ring 15 and fixed, and then the packaging box that needs to be punched is put on the outside of the lining seat 21, one end of the packaging box is in contact with the outside of the clamping ring 15, and one end of the lining seat 21 is exposed to the packaging box. At this time, the stamping equipment drives the tool to descend and act on the surface of the packaging box, so that the lifting seat 14 is pressed down inside the guide device 13, and the spring 133 is compressed and contracted. The lifting seat 14 is guided by the guide rod 132 to descend to the bottom of the clamping ring 15 and the exposed part of the lining seat 21 contacts the top of the support bar 12. This can effectively prevent the installed packaging box from being damaged by pressure. As the stamping equipment continues to descend, the tool punches the cardboard punching hole position, and the waste generated falls into the inside of the lining seat 21. The high-speed air introduced by the air outlet nozzle 16 blows out the waste generated, thereby realizing rapid discharge.

[0029] It should be noted that the parts not covered in the present invention are the same as the existing technology or can be implemented by using the existing technology; the various drives in the present invention can be implemented by using corresponding power structures such as cylinders, oil cylinders, electric cylinders, motors, etc. in combination with connecting rods, guide rods, etc., and are not limited to the description in the specification and the structure in the drawings.
