Description

Technical Field

[0001] This utility model relates to the field of waste collection technology, and in particular to a waste collection device for printing equipment. Background Technology

[0002] When printing on packaging rolls, printing presses typically perform edge trimming simultaneously. Because existing printing presses lack waste edge recycling devices, the waste edges generated during trimming are haphazardly piled up around the press. Since the rolls used for printing are generally quite long, the area around the machine quickly becomes cluttered with the trimmed waste edges shortly after the press starts operating. This waste not only affects the production environment but also causes some fragments to get caught on the press frame's rollers, significantly impacting machine operation.

[0003] The utility model with publication number CN212146699U discloses a printing waste collection device, including a main body and an exhaust fan. A bearing is fixedly installed on the upper part of the rear box wall of the inner cavity of the main body. A drive shaft is fixedly connected to the output end of the motor. The end of the drive shaft away from the motor passes through the front box wall of the main body and is fixedly connected to the bearing. Several sets of connecting rods are fixedly installed in a ring array on the outer part of the drive shaft inside the main body. Several sets of blades are fixedly installed in a ring array on the outer wall of each connecting rod. The filter grid is located below the drive shaft.

[0004] In the above technical solution, the inventors have found at least the following problem: during the cutting process of waste material by the blade, due to the influence of the exhaust fan, some waste material will be adsorbed on the surface of the filter grid, making it impossible for the blade to cut the waste material, resulting in a decrease in cutting efficiency. Therefore, a waste material collection device for printing equipment is proposed. Utility Model Content

[0011] This utility model has the following beneficial effects:

[0012] In this invention, a motor drives a rotating shaft and rotating blades to rotate. The rotating blades drive a cutting blade to cut larger pieces of waste material entering the housing. Simultaneously, an air compressor generates gas, which enters the housing through an air pipe, ventilation channel, and jet duct, blowing up the waste material above the filter grid to facilitate cutting. Afterward, the air compressor is turned off, allowing the cut smaller pieces of waste material to pass through the filter grid and enter the collection drawer, thus completing the cutting of large pieces of waste material and facilitating waste collection by workers.

[0018] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1-3 One embodiment of this utility model is a waste collection device for printing equipment, which includes a box 1, a motor 2 fixedly installed on one side of the box 1, a protective shell 11 fixedly installed on the outer surface of the box 1, and the motor 2 is located inside the protective shell 11. The protective shell 11 can protect the motor 2 and reduce the chance of external objects hitting the motor 2.

[0020] Furthermore, a feeding funnel 12 is fixedly installed on the top of the box 1, and a top cover 13 is movably connected to the top of the feeding funnel 12. A ventilated mesh 14 is provided inside the top cover 13. The feeding funnel 12 allows workers to easily add waste material into the box 1. After adding waste material, workers can place the top cover 13 above the feeding funnel 12 to prevent waste material from flying out of the box 1. The ventilated mesh 14 can maintain the air pressure balance inside and outside the box 1.

[0021] Furthermore, a rotating shaft 3 is fixedly installed at the output end of the motor 2, which passes through the housing 1. Rotating blades 4 are symmetrically installed on the outer surface of the rotating shaft 3, and cutting blades 5 are symmetrically installed on the outer surface of the rotating blades 4. A filter grille 6 is fixedly installed on the inner wall of the housing 1 below the rotating shaft 3. An air compressor 7 is fixedly installed on the outer surface of the housing 1, and an air pipe 8 is fixedly installed at the outlet end of the air compressor 7. Both the rotating shaft 3 and the rotating blades 4 have interconnected ventilation slots 9. An air jet slot, connected to the ventilation slot 9, is opened on the outer surface of the rotating blades 4. A filter screen 15 is fixedly installed on the inner wall of the air jet slot inside the rotating blades 4. The filter screen 15 reduces the amount of waste material inside the housing 1 entering the air jet slot. The end of the rotating shaft 3 furthest from the motor 2 extends to the outside of the housing 1 and is connected to a rotary joint 10. One end of the air pipe 8 is connected to the rotary joint 10.

[0022] Furthermore, a collection drawer 16 is slidably connected to the inner bottom wall of the box 1. The cut waste material can fall into the collection drawer 16 through the filter grid 6, thereby completing the collection of waste material. The bottom of the box 1 is equipped with locking casters 17, which can facilitate the movement of the box 1 by the staff and meet the needs of use in different places.

[0023] Working principle: During use, the feeding funnel 12 allows workers to easily add waste material into the box 1. After adding the waste material, the workers can place the top cover 13 on top of the feeding funnel 12, and then start the motor 2 and the air compressor 7. The motor 2 can drive the rotating shaft 3 and the rotating blade 4 to rotate. The rotating blade 4 can drive the cutting blade 5 to cut the larger pieces of waste material that have entered the box 1. At the same time, the air compressor 7 can generate gas, which enters the box 1 through the air pipe 8, the ventilation slot 9 and the air jet slot, blowing up the waste material above the filter grid 6, thus facilitating the cutting blade 5 to cut it. After that, the air compressor 7 is turned off, allowing the cut small pieces of waste material to enter the collection drawer 16 through the filter grid 6, thus completing the cutting of large pieces of waste material and facilitating the collection of waste material by workers.
