Description

Technical Field

[0001] This utility model relates to the field of cardboard box forming machine technology, specifically to a waste removal device for a cardboard box printing machine. Background Technology

[0002] Printing presses, as a type of cardboard box forming equipment, are widely used in the market. Cardboard boxes are first placed in the paper feeding section for individual conveying. These boxes, conveyed side-by-side, are then transported to subsequent printing, cutting, and coding equipment for processing. During the cutting process, the cardboard boards need to be trimmed to ensure they can be assembled into the desired box structure. Sometimes, scraps of paper adhere to the surface of the cardboard boards. If these scraps are not treated and are conveyed along with the cardboard boards, they will enter the subsequent processing equipment, affecting subsequent printing and coding operations. Therefore, a waste removal device is needed to clean the paper scraps adhering to the cardboard boards. Common waste removal devices include... The lower two sets of rotatable conveyor rings allow the cardboard to pass through the gap between them. As the cardboard passes through, the vibrating roller rotates along with the eccentrically mounted mounting plate and vibrating rod. As the vibrating roller rotates, the vibrating rod touches the lower conveyor ring and causes it to vibrate. This vibration causes the cardboard to detach from its surface. At the same time, a waste removal fan is installed at the top of the waste removal device frame. The waste removal fan directly blows the upper surface of the cardboard, causing any cardboard pieces that cannot be shaken off to fall off. The removed cardboard is then scattered at the bottom of the frame. After a long period of waste removal operations, workers need to regularly clean and collect the scattered cardboard pieces, which is time-consuming, labor-intensive, and inconvenient.

It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0017] like Figure 1-2 As shown, this utility model embodiment provides a waste removal device for a carton printing machine, including a hollow frame 1. A baffle 2 is provided circumferentially at the lower end of the frame 1, making the lower end of the frame 1 form a waste recycling chamber 3 with an opening at the top. A vibrating conveying mechanism is provided on the frame 1 above the corresponding waste recycling chamber 3. A waste removal fan 4 is provided on the top of the frame 1 above the corresponding vibrating conveying mechanism. A negative pressure recycling mechanism is provided inside the waste recycling chamber 3. An outlet is provided on the front side of the frame 1 at the position corresponding to the negative pressure recycling mechanism (the outlet is located on the front side of the frame 1, not shown in the figure). The negative pressure recycling mechanism can be moved outward along the outlet. An adsorption plate 5 is provided on the top of the negative pressure recycling mechanism. An openable cover is provided on the frame 1 at the position corresponding to the outlet.

[0018] The negative pressure recovery mechanism includes a movable recovery platform 6 installed in the waste recovery chamber 3. The recovery platform 6 has a hollow structure. A negative pressure fan 7 is installed inside the recovery platform 6 to draw air outward. The exhaust port of the negative pressure fan 7 extends to the outside of the frame 1 through a telescopic pipe. Several air holes 7a are evenly distributed on the top of the recovery platform 6.

[0019] The bottom of the waste recycling chamber 3 is provided with a slide rail 8, and the bottom of the recycling platform 6 is provided with a slide seat 9, which is slidably mounted on the slide rail 8.

[0020] The adsorption plate 5 includes a rigid plate installed on the top of the recycling platform 6. The top surface of the rigid plate is provided with adhesive, and air holes 5a are provided on the rigid plate at the positions corresponding to each air hole 7a.

[0021] The rigid plate is fixed to the top of the recycling table 6 by means of the four corners of the rigid plate.

[0022] The oscillating conveyor mechanism includes upper drive rollers 11 and lower drive rollers 12 arranged on both sides of the top of the frame 1. Several conveying rubber strip rings 13 are arranged between the upper drive rollers 11 and the lower drive rollers 12 on both sides. Several annular grooves are evenly distributed on the outer periphery of each drive roller. The two ends of the conveying rubber strip rings 13 are respectively fitted into the annular grooves on the two drive rollers. A gap is provided between the upper and lower conveying rubber strip rings 13 to facilitate the passage of cartons. Several oscillating rollers 14 are evenly distributed in the transverse direction inside the lower conveying rubber strip ring 13. Several mounting plates 15 are evenly distributed on the oscillating rollers 14. The mounting plates 15 are eccentrically connected to the oscillating rollers 14. An oscillating rod 16 is arranged on the outer periphery of each mounting plate 15 on the same oscillating roller 14.

[0023] The upper drive roller 11, the lower drive roller 12, and the vibrating roller 14 are driven to rotate by motors.

[0024] The frame 1 is equipped with a support 17 at the top of its conveying end. The top of the support 17 is provided with an inclined platform. The support 17 is equipped with a waste cleaning fan 4 on its inclined platform. The air outlet of the waste cleaning fan 4 is inclined downward and arranged towards the vibrating conveying mechanism.

[0025] The working principle of this utility model is as follows: First, the starter motor drives the vibrating rollers 14 of each transmission roller to rotate. At this time, the conveying rubber strip ring 13 will rotate along the transmission roller. When the vibrating roller 14 rotates, the mounting plate 15 will rotate together. Since the mounting plate 15 and the vibrating roller 14 are eccentrically mounted, the mounting plate 15 and the vibrating rod 16 on it will swing irregularly. The swinging vibrating rod 16 will contact the lower conveying rubber strip ring 13, causing the lower conveying rubber strip ring 13 to swing together. The conveying rubber strip ring 13 plays a role in transmitting and conveying the carton board. The carton board passes through the gap between the upper and lower conveying rubber strip rings 13 in sequence. The swinging lower conveying rubber strip ring 13 will pat the carton board, causing the paper pieces stuck to its surface to bounce up and fall off. At the same time, the waste removal fan 4 moves from the upper end of the frame 1 to the lower end of the conveyor belt. Downward airflow sweeps the upper surface of the cardboard, ensuring that the paper scraps completely detach from the cardboard. Simultaneously, the negative pressure fan 7 inside the recycling station 6 creates a negative pressure environment, attracting the fallen paper scraps. The paper scraps are drawn to the adsorption plate 5 at the top of the recycling station 6 by the air vents 7a. After the vibration cleaning process is complete, the cover of the frame 1 is opened, and the recycling station 6 is pulled out along the slide rail 8. The retaining screws 10 at each corner of the adsorption plate 5 are removed, allowing the adsorption plate 5 to be removed. This allows for centralized processing of the recycled paper scraps. A new adsorption plate 5 is then installed and secured. Finally, the recycling station 6 is pushed back into the frame 1 to continue the paper scrap recycling process.

[0026] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
