Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of conveying devices, and in particular relates to a waste conveying device for printing plants. Background Technology
[0002] During the operation of a printing plant, waste printed sheets are generated due to quality problems such as misregistration, color deviation, and uneven ink color. In addition, scraps and defective products are also generated in the processing stages such as cutting and folding. These waste paper materials can be recycled and reused. After being processed by sorting, pulping, impurity removal, bleaching and other processes, they are made into recycled paper. During transportation, conveying devices are required.
[0003] Existing conveying devices are generally conveyor belts or conveyor troughs used when conveying from high to low. Although these devices can transport waste paper, the waste paper is in a loose state and has a large volume, making the transfer of waste paper extremely inconvenient.
[0004] To address these issues, we provide a waste conveying device for printing plants. Utility Model Content

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1
[0027] Please see Figures 1 to 3This utility model is a waste conveying device for printing plants, including a base frame 100 and a collection hopper 200; a compression chamber 500 is fixedly connected to the top of the base frame 100, and a compression component 600 for compressing waste paper is provided inside the compression chamber 500; a crushing chamber 300 is fixedly connected to the bottom of the collection hopper 200, and a crushing component 800 for crushing waste paper is provided inside the crushing chamber 300; a connecting component 400 is installed between the crushing chamber 300 and the compression chamber 500.
[0028] The compression assembly 600 includes an electric cylinder 601 fixedly connected to the top of the base frame 100 and a compression plate 602 movably sleeved inside the compression chamber 500. The output end of the electric cylinder 601 passes through the back of the compression chamber 500 and is fixedly connected to the back of the compression plate 602. A baffle plate 603 is fixedly connected to the back of the compression plate 602 and fits against the top of the inner cavity of the compression chamber 500. The baffle plate 603 extends through the back of the compression plate 602 to the outside. By pushing the compression plate 602 with the electric cylinder 601, the waste can be compressed, thereby reducing the volume of the waste and making the transfer more convenient. The baffle plate 603 can block the connecting pipe 503 to prevent the waste from falling into the back of the compression plate 602.
[0029] Specifically, the crushing assembly 800 includes two crushing rollers 801 rotatably connected to the crushing chamber 300, and two shafts of the two crushing rollers 801 extend through the crushing chamber 300 to the outside. One end of each shaft of the two crushing rollers 801 is fixedly connected to a drive gear 802, and the two drive gears 802 mesh with each other. A drive motor 804 is fixedly connected to the outside of the crushing chamber 300, and the shaft of one of the crushing rollers 801 is fixedly connected to the output end of the drive motor 804. The two crushing rollers 801 can crush the printing waste falling between them, thereby reducing the volume of the waste and making the transfer more convenient.
[0030] The compression chamber 500 includes a chamber body 501 fixedly connected to the top of the base frame 100. A connecting pipe 503 is fixedly connected to the top of the chamber body 501. A grooved door 502 is rotatably connected to the lower edge of the front of the chamber body 501. Insertion holes are provided on both sides inside the door 502. A door lock 700 for fixing the door 502 is provided on the top of the chamber body 501.
[0031] The connecting assembly 400 includes an upper sleeve 401 fixedly connected to the bottom of the crushing chamber 300 and a lower sleeve 402 fixedly connected to the top of the connecting pipe 503. The upper sleeve 401 is movably sleeved inside the lower sleeve 402. By adjusting the length of the upper sleeve 401 inside the lower sleeve 402, the device can be installed in factories with different floor heights, making installation more convenient.
[0032] Furthermore, two guide plates 803 are fixedly connected to the upper part of the inner cavity of the crushing chamber 300, and the two guide plates 803 are distributed in a V-shape. The waste material can be guided between the two crushing rollers 801 through the two guide plates 803.
[0033] A movable cutter 604 is fixedly connected to the upper edge of the front side of the compression plate 602, and a fixed cutter 605 is fixedly connected to the lower edge of the inner cavity of the connecting pipe 503 facing the electric cylinder 601. The movable cutter 604 and the fixed cutter 605 can cut the waste material to prevent thicker waste material from getting stuck in the compression plate 602.
[0034] The operation process of this embodiment is as follows: When it is necessary to transport printing waste, firstly, the drive motor 804 is started to drive one of the crushing rollers 801 to rotate. Then, the two meshing drive gears 802 drive the other crushing roller 801 to rotate in the opposite direction. After that, the worker puts the waste into the collection hopper 200. Then, the printing waste falls between the two crushing rollers 801. Subsequently, the two crushing rollers 801 rotating in the opposite direction can crush the falling printing waste. Then, the crushed printing waste enters the chamber 501 along the upper sleeve 401 and the lower sleeve 402. Then, the electric cylinder 601 is started. Then, the output end of the electric cylinder 601 pushes the compression plate 602 to push the printing waste in the chamber 501 toward the chamber door 502, thereby compacting the printing waste, reducing the volume of the printing waste, and making the transfer more convenient. Example 2
[0035] Please see Figure 3 Based on the first specific embodiment, the door lock 700 includes two collinear sliding seats 701 fixedly connected to the top of the compartment 501 and a sliding frame 704 perpendicular to the two sliding seats 701. Insert rods 702 are movably sleeved inside each of the two sliding seats 701, and the opposite ends of the two insert rods 702 are wedge-shaped. Sliding columns 703 are rotatably connected to the opposite ends of the two insert rods 702. A sliding rod 705 is movably sleeved inside the sliding frame 704. A guide seat 706 is fixedly connected to the end of the sliding rod 705 facing the sliding seat 701. Two guide grooves 707 are formed inside the guide seat 706, and the two guide grooves 707 are V-shaped. Two sliding columns 703 are located inside the two guide grooves 707. A return spring 708 is movably sleeved outside the sliding column 703, and the return spring 708 is located between the guide seat 706 and the sliding frame 704. A door handle 709 is fixedly connected to the top of the sliding rod 705.
[0036] Specifically, the two insert rods 702 are wedge-shaped at opposite ends and are inserted into the insert holes on both sides inside the compartment door 502.
[0037] The operation process of this embodiment is as follows: When it is necessary to open the compartment door 502, the door handle 709 is pushed to move the slide rod 705, thereby causing the guide seat 706 to compress the return spring 708. Then, under the guidance of the two guide grooves 707, the two sliding columns 703 drive the two insertion rods 702 to move closer together, so that the wedge-shaped ends of the two insertion rods 702 leave the corresponding insertion holes, thereby making it convenient and quick to open the compartment door 502 and avoiding the compartment door 502 from getting stuck.
