DETAILED DESCRIPTION

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0021] like Figure 1 , 4 As shown in Figure 5, this embodiment provides a waste cleaning machine, which consists of a frame 1, 3 groups of cardboard conveying assemblies (the number of cardboard conveying assemblies is set according to the width or length of the cardboard), a high-pressure fan assembly, a vibrating square steel assembly and a waste cleaning brush assembly.

[0022] The frame 1 is composed of a truss body 101 and two vertical frame bodies 102. The truss body 101 is horizontally arranged and its two ends are fixedly installed on the top of the vertical frame body 102. The vertical frame body 102 is vertically arranged.

[0023] like Figure 1 and 2As shown, the cardboard conveying assembly is composed of an upper support frame 13, a lower support frame 14, an upper conveyor belt 15, a lower conveyor belt 16, an inlet lower arc piece 17, an adjustment block 18 and an inlet upper arc piece 19. The upper conveyor belt 15 is installed on the side of the upper support frame 13. Specifically, a gear set and a gear shaft are rotatably installed on the upper support frame 13. The two ends of the upper conveyor belt 15 are meshed with the gears. The upper conveyor belt 15 is driven by a motor, so that the upper conveyor belt 15 works. The lower conveyor belt 16 is installed on the side of the lower support frame 14. Specifically, a gear set and a gear shaft are rotatably installed on the lower support frame 14. The two ends of the lower conveyor belt 16 are meshed with the gears. The lower conveyor belt 16 is driven by a motor, so that the lower conveyor belt 16 works. A cardboard conveying channel is formed between the upper conveyor belt 15 and the lower conveyor belt 16. The cardboard is conveyed through the cardboard conveying channel. During the conveying process, the cardboard is subjected to high-pressure blowing, vibration and brushing by the high-pressure fan assembly, the vibrating square steel assembly and the waste brush assembly. The position of the upper conveyor belt 15 can be adjusted up and down to adjust the thickness of the cardboard conveying channel to adapt to cardboards of different thicknesses: specifically, the upper support frame 13 is composed of a fixed frame and an adjusting frame, the fixed frame and the adjusting frame are slidably connected by a screw (or a slide), and the upper conveyor belt 15 and its driving source (gear set, gear shaft, motor) are both installed on the adjusting frame.

[0024] The front end of the lower support frame 14 is fixedly installed with the lower inlet arc piece 17; the front end of the upper support frame 13 is installed with an adjustment block 18 and an upper inlet arc piece 19, the adjustment block 18 is fixedly installed on the upper support frame 13 by bolts, the side of the upper inlet arc piece 19 is extended and a waist-shaped groove is opened in the extended part, and the upper inlet arc piece 19 is slidably set on the adjustment block 18 through the waist-shaped groove by bolts. The arc inlet (also known as: eight-shaped inlet) of the cardboard conveying channel is formed between the upper inlet arc piece 19 and the lower inlet arc piece 17. The upper inlet arc piece 19 can be adjusted up and down, so as to adjust the thickness of the inlet of the cardboard conveying channel to adapt to cardboards of different thicknesses.

[0025] The high-pressure fan assembly, the vibrating square steel assembly and the waste cleaning brush assembly are arranged in sequence along the direction from the inlet to the outlet of the cardboard conveying channel.

[0026] The high-pressure fan assembly consists of a high-pressure fan, a ventilation pipeline and a fan blowing port 2. The high-pressure fan is installed in the truss body 101, so it is not shown in the figure; the ventilation pipeline is not shown in the figure. The high-pressure fan and the fan blowing port 2 are connected by the ventilation pipeline, and the fan blowing port 2 is fixedly installed on the upper support frame 13 through a connecting rod. The fan blowing port 2 is above the cardboard conveying channel. When the high-pressure fan starts working, the fan blowing port 2 blows air downward to blow away most of the paper scraps or waste edges.

[0027] like Figure 1 and 3As shown, the vibrating square steel assembly is composed of square steel 3, T-shaped connecting plate 4, bearing seat 5, chain transmission assembly 6, servo motor 7, slide rail 8, slider 9, elastic member 10 and first L-shaped connecting plate 11. Both ends of the square steel 3 are rotatably mounted on the T-shaped connecting plate 4 through the bearing seat 5; one end of the square steel 3 is connected to the servo motor 7 through the chain transmission assembly 6 (the chain transmission assembly 6 is composed of a gear shaft, a gear set, a chain, etc.). Therefore, when the servo motor 7 is working, it drives the active gear to rotate, and through the action of the chain, the passive gear installed at one end of the square steel 3 rotates, and finally the square steel 3 rotates. Due to the square structure of the square steel 3 and its location below the cardboard conveying channel (that is, the square steel 3 is below the cardboard), the square steel 3 contacts or separates from the cardboard when rotating, thereby forming a vibration effect, vibrating off some paper scraps or waste edges, or vibrating the paper scraps or waste edges on the cardboard to an undulating state, preventing the paper scraps or waste edges from being close to the cardboard, so as to facilitate the subsequent brush 12 to brush them off.

[0028] Furthermore, when the square steel 3 contacts the cardboard, in order to avoid the square steel 3 from having a hard contact with the cardboard, an "elastic" square steel 3 is designed: the slide rail 8 is fixedly mounted on the vertical frame 102 of the frame 1, the slider 9 is slidably connected to the slide rail 8, the slider 9 is fixedly connected to the T-shaped connecting plate 4, the T-shaped connecting plate 4 is fixedly connected to the first L-shaped connecting piece 11, the first L-shaped connecting piece 11 is hinged to the bottom end of the elastic member 10 (the elastic member 10 is mainly composed of a spring), and the top end of the elastic member 10 is fixedly mounted on the vertical frame 102 of the frame 1. A waist-shaped groove is provided on the first L-shaped connecting piece 11, and the installation position of the T-shaped connecting plate can be adjusted. A limit block is fixedly installed at the bottom of the slide rail 8 to limit the position where the slider 9 slides downward.

[0029] The waste brush assembly includes a brush 12 and a second L-shaped connecting piece 20, one side of the second L-shaped connecting piece 20 is fixedly connected to the brush 12, and the other side of the second L-shaped connecting piece 20 is provided with a waist-shaped groove and is slidably arranged on the side wall of the vertical frame body 102 of the frame 1 through bolts passing through the waist-shaped groove. The brush 12 just contacts the upper surface of the cardboard, so that the brush 12 can brush away the paper scraps or waste edges on the upper surface of the cardboard.

[0030] A waste paper conveyor belt 21 is installed between the bottoms of the two vertical frames 102 through a driving source (gear set, gear shaft, motor). The heights of the cardboard conveying assembly, the high-pressure fan assembly, the vibrating square steel assembly and the waste cleaning brush assembly are all greater than the height of the waste paper conveyor belt 21. Therefore, the processed paper scraps or waste edges fall on the waste paper conveyor belt 21 and are collected and transported by the waste paper conveyor belt 21.

[0031] A control method based on the above waste stripping machine comprises: 1. Monitor the position of cardboard in real time.

[0032] 2. Based on the thickness of the cardboard, adjust the thickness of the cardboard conveying channel.

[0033] 3. When the cardboard passes through the inlet of the cardboard conveying channel, the high-pressure fan is controlled to start working, and high-pressure air is blown downward from the fan air outlet 2 to blow away the paper scraps or waste edges on the surface of the cardboard.

[0034] 4. When the probe at the rear end of the fan air outlet 2 detects the cardboard, the servo motor 7 is controlled to start working, the square steel 3 starts to rotate and under the elastic action of the elastic member 10, contacts or separates from the lower surface of the cardboard, thereby forming a vibration effect, vibrating off the paper scraps or waste edges on the cardboard, or changing the close contact state of the paper scraps or waste edges on the cardboard.

[0035] 5. Adjust the position of the brush 12 so that the brush 12 just contacts the upper surface of the cardboard, so that the brush 12 can clean the paper scraps or waste edges on the upper surface of the cardboard.

[0036] 6. Finally, the waste paper conveyor belt 21 is controlled to start working, and the paper scraps or waste edges dropped on the waste paper conveyor belt 21 are collected and conveyed to the waste paper box.

[0037] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present invention by using the above disclosed methods and technical contents without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes. Therefore, all equivalent changes made according to the shape, structure and principle of the present invention without departing from the content of the technical solution of the present invention should be included in the protection scope of the present invention.
