Description

Technical Field

[0001] This utility model relates to the field of book printing equipment technology, specifically to a waste paper collection system for book printing. Background Technology

[0002] During the book printing process, the cutting machine generates a large amount of waste paper when cutting the printing paper. Currently, the waste paper is usually collected in a collection container below the cutter's outlet, relying on its own weight to fall into the container. However, this method has many problems. For example, because the cut waste paper is scattered at the outlet, some may fall outside the collection container, causing a messy workshop environment. Moreover, the waste paper tends to accumulate near the outlet under the influence of gravity and airflow, affecting the normal operation of the cutting machine, and cleaning is also quite troublesome.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] A book printing waste paper collection system, combined with Figure 1 As shown, the device includes a chute 1, which is inclinedly positioned at the bottom of the waste paper discharge port of the book printing cutter. The chute 1 is used to guide the falling waste paper. A collection pipe 2 is located at the bottom of the chute 1. The end of the collection pipe 2 near the chute 1 is horizontally positioned and sealed at the end. Figure 2 As shown, the collecting pipe 2 has an inlet on its side wall near the chute 1, which is connected to the bottom of the chute 1. An induced draft fan 3 is connected to the end of the collecting pipe 2 away from the chute 1. The induced draft fan 3 is used to draw air, thereby collecting waste paper and conveying it to the rear. The outlet of the induced draft fan 3 is connected to a storage box 5 via a connecting conveying pipe 4. The storage box 5 is used to separate the waste paper from the air and store the waste paper.

[0019] The chute 1 is shaped like a flat mouth surrounded by four sides. This structural design of the chute 1 can guide the falling waste paper and prevent the waste paper from falling irregularly at the waste paper outlet, effectively preventing the waste paper from falling out.

[0020] Both the collection pipe 2 and the conveying pipe 4 are flexible corrugated pipes, which not only allow for easy adjustment of the pipe's direction and position, but also enable them to adapt to a certain degree of displacement and vibration, making them easier to arrange in different installation environments.

[0021] The induced draft fan 3 is a centrifugal induced draft fan with a large air volume and air pressure, which can effectively suck up the waste paper and transport it to the storage box 5.

[0022] Sealing rings are installed at the connections of chute 1 and collection pipe 2, collection pipe 2 and induced draft fan 3, induced draft fan 3 and conveying pipe 4, and conveying pipe 4 and storage box 5. These sealing rings tightly wrap the connections, achieving a sealed connection between all components of the entire system. The purpose of the sealed connection is to prevent waste paper from leaking from the connection during transmission, while ensuring that the induced draft fan 3 minimizes air leakage during the induced draft process, improving the induced draft efficiency, and thus ensuring that waste paper can be collected smoothly and efficiently.

[0023] The storage box 5 includes a storage box body, which includes a frame. The frame serves as the structural support for the storage box body. The bottom of the frame is funnel-shaped, and a feed inlet 51 is located on the top side of the frame, which is connected to the conveying pipe 4. A discharge outlet 52 is located at the bottom of the frame. The funnel-shaped design of the bottom of the frame helps the waste paper to gather towards the discharge outlet 52 under its own gravity, making it easy for the waste paper to fall out. A detachable sealing cover 53 is installed on the discharge outlet 52. When it is necessary to clean the waste paper, the sealing cover 53 can be opened to let the waste paper stored in the storage box body fall out. The frame is also wrapped with a sealing cloth 54, with the feed inlet 51 and discharge outlet 52 exposed. After the waste paper and the induced air enter the storage box body, the induced air can be discharged through the pores of the sealing cloth 54, thereby separating the waste paper from the induced air and storing the waste paper in the storage box body.

[0024] The storage box 5 also includes a support leg 55, which is located at the bottom of the storage box body and is used to support the storage box body.

[0025] The working principle of this utility model is as follows:

[0026] During the paper cutting stage of book printing, the waste paper generated after the cutting machine cuts the book paper falls from the waste paper outlet of the cutting machine. Because a chute 1 is set at the bottom of the waste paper outlet at an angle, the waste paper slides down the chute 1 under the action of gravity. The chute 1 is a flat-mouth shape with four sides, which can guide the waste paper to accurately enter the feed port at the bottom of the chute 1, which is connected to the collection pipe 2.

[0027] Waste paper entering the collection pipe 2 is propelled by the continuous influx of waste paper and drawn towards the discharge end of the collection pipe 2 by the backward suction force generated by the induced draft fan 3 (the air pressure generated by the centrifugal induced draft fan makes the air pressure at the rear of the pipe lower than at the front, thus creating a backward suction force). The induced draft fan 3 operates with a large air volume and air pressure, further driving the waste paper through the induced draft fan 3 towards the conveying pipe 4. Under the continuous suction force of the induced draft fan 3, the conveying pipe 4 transports the waste paper to the storage box 5.

[0028] When waste paper enters the storage box 5 through the feed inlet 51 on the top side of the storage box 5 with the induced draft, the sealing cloth 54 plays a crucial role. The pores in the sealing cloth 54 allow the induced draft to pass through and be discharged, thereby reducing the air pressure inside the storage box. After losing the induced draft, the waste paper falls under its own gravity and is collected in the funnel-shaped structure at the bottom of the storage box, converging towards the discharge port 52. In this process, the waste paper and the induced draft are effectively separated, and the waste paper is ultimately stored inside the storage box. When the waste paper stored in the storage box needs to be cleaned, the sealing cover 53 of the discharge port 52 is opened, and the waste paper falls out from the discharge port 52, thus completing the collection process of the cutting waste paper for book printing.
