Description
Technical Field
[0001] This utility model relates to the technical field of packaging box printing production equipment, and in particular to an automatic waste removal device for packaging box printing production. Background Technology
[0002] In packaging box printing production, waste removal is a crucial step in ensuring product quality. Traditional manual waste removal methods are inefficient and prone to product damage due to improper operation. With the development of automation technology, mechanical waste removal equipment has gradually replaced manual labor and become the mainstream solution. However, existing automated waste removal equipment still has shortcomings in terms of precision, speed, and adaptability, making it difficult to meet the demands of high-precision and high-efficiency production. Furthermore, different packaging box sizes have different requirements for waste removal equipment, and the poor versatility of existing equipment leads to increased production costs.
[0003] As shown in the reference case "A packaging box production and processing edge cutting device" announcement number "CN216099091U", this utility model is equipped with a discharge hole and a recycling box, which can recycle the cut-off edge waste, save the operator's cleaning time, reduce labor intensity, improve production efficiency, facilitate maintenance, and is cost-effective.
[0004] The aforementioned application involves guiding waste into a recycling bin through a discharge hole when recycling waste. However, when cutting different packaging boxes, the waste produced varies in size. Since the diameter of the discharge hole is fixed, some smaller waste cannot fall accurately into the discharge hole, while some larger waste cannot pass through the discharge hole, resulting in significant limitations in waste recycling. Utility Model Content
[0005] Therefore, it is necessary to provide an automatic waste removal device for packaging box printing production to address the significant limitations of waste recycling.
[0006] An automatic waste removal device for packaging box printing production includes: a frame, and multiple upper conveyor rollers and multiple lower conveyor rollers installed on the inner wall of the frame;
[0007] The waste removal mechanism includes a cutting assembly, a cutting table is provided below the cutting assembly, multiple conveyor belts are provided on one side of the cutting table, and collection boxes are provided below the multiple conveyor belts.
[0008] In one embodiment, multiple conveyor belts are arranged side by side, the spacing between the multiple conveyor belts is greater than the width of the conveyor belts, and a drive motor is fixedly connected to the surface of the frame, and the multiple conveyor belts are driven by the drive motor.
[0009] In one embodiment, an electric push rod is fixedly connected to the inner wall of the frame, and a scraper is fixedly connected to the drive end of the electric push rod. The scraper is disposed on the upper surface of the cutting table, and the bottom end of the scraper is slidably connected to the lower surface of the cutting table.
[0010] In one embodiment, sensors are provided on both sides of the frame, and the sensors are flush with the upper surface of the cutting table.
[0011] In one embodiment, the collection box is flat-bottomed and conical, with its top end fixedly connected to the inner wall of the frame and its bottom end located below the frame.
[0012] In one embodiment, a drawer is provided at the bottom opening of the collection box, and the drawer is inserted into the collection box.
[0013] In one embodiment, two guide strips are provided between the upper conveying roller and the lower conveying roller. One end of each guide strip is curved. The two guide strips are arranged opposite to each other and are fixedly connected to the inner walls of both sides of the frame.
[0014] In one embodiment, a gear is fixedly connected to one end of the upper conveyor roller and the lower conveyor roller, and the two sets of gears are connected by auxiliary gears. The number of upper conveyor rollers is less than that of lower conveyor rollers, and the plurality of upper conveyor rollers are arranged in the middle position of the plurality of lower conveyor rollers.
[0015] Beneficial effects
[0016] 1. By setting up multiple parallel conveyor belts and setting the spacing between each pair of conveyor belts to be greater than the width of the conveyor belts, the waste generated after the packaging boxes are cut will fall into the collection box through the gap between the two conveyor belts when the packaging boxes pass through the conveyor belts at the same time. Because the gap between the conveyor belts is large, the waste generated when the cutting component cuts packaging boxes of different sizes will fall into the collection box, reducing the limitations of waste recycling.
[0017] 2. By setting up sensors in conjunction with the cutting mechanism to cut packaging boxes, when it is necessary to cut packaging boxes of different sizes, the cutting system can be directly programmed through the control system, increasing the versatility of the device and avoiding the need to change the cutting tools when cutting packaging boxes of different sizes, thus reducing production costs.

[0031] The following is combined Figures 1-5 This invention describes an automatic waste removal device for packaging box printing production.
[0032] In one embodiment, an automatic waste removal device for packaging box printing production includes: a frame 100, and multiple upper conveyor rollers 210 and multiple lower conveyor rollers 200 installed on the inner wall of the frame 100.
[0033] The waste removal mechanism 300 includes a cutting assembly 310, a cutting table 320 below the cutting assembly 310, multiple conveyor belts 330 on one side of the cutting table 320, and a collection box 340 below the multiple conveyor belts 330.
[0034] like Figure 3 , Figure 4 and Figure 5 As shown, multiple conveyor belts 330 are arranged side by side, with the spacing between them greater than the width of each conveyor belt 330. A drive motor 331 is fixedly connected to the surface of the frame 100, and the multiple conveyor belts 330 are driven by the drive motor 331. An electric push rod 321 is fixedly connected to the inner wall of the frame 100, and a scraper 322 is fixedly connected to the drive end of the electric push rod 321. The scraper 322 is located on the upper surface of the cutting table 320, and its bottom end is slidably connected to the lower surface of the cutting table 320. Sensors 350 are arranged on both sides of the frame 100, and are flush with the upper surface of the cutting table 320. The collection box 340 is flat-bottomed and conical. The top of the collection box 340 is fixedly connected to the inner wall of the frame 100, and its bottom end is located below the frame 100. A drawer 341 is provided at the bottom opening of the collection box 340, and the drawer 341 is inserted into the collection box 340.
[0035] In this embodiment, the cutting assembly 310 includes a movable frame slidably connected to the inner walls of both sides of the frame 100. One side of the movable frame is connected to a threaded rod provided on the inner wall of the frame 100. The threaded rod is driven by a motor, causing the movable frame to move along the surface of the frame 100. An electric slide rail is fixedly connected to the inner wall of the movable frame, and a slide block is slidably connected to the surface of the electric slide rail. A laser cutting head is slidably connected to the slide block, and the laser cutting head moves up and down via a hydraulic rod. This device is equipped with a control system. All electric components in the cutting assembly 310 are connected to the control system via electrical signals. When cutting different packaging boxes, the control system needs to be programmed in advance. The direction of movement of the movable frame along the frame 100 is denoted as the X-axis, the direction of movement of the slide block on the electric slide rail is denoted as the Y-axis, and the direction of movement of the laser cutting head along the slide block is denoted as the Z-axis. The laser cutting head can be programmed through the control system. The sensor 350 is model E3Z-T61. Its working principle is: the transmitting end emits an infrared beam with a modulation frequency. When the packaging box enters the sensing area... The surface of the packaging box creates a blocking effect on the light beam. The photosensitive element at the receiving end captures changes in the intensity of the reflected light. When the receiving end cannot capture the infrared light beam, it feeds back to the control system via an electrical signal. At this time, the control system starts the cutting assembly 310. A protective shell is provided on the side of the conveyor belt 330 to isolate waste from contact with the drive wheel inside the conveyor belt 330 and prevent damage to the conveyor belt 330. A strip-shaped opening is provided in the middle of the cutting table 320. The bottom end of the scraper 322 passes through the strip-shaped opening and is connected to the lower surface of the cutting table 320. By setting the groove opening of the cutting table 320 downward, the influence of dust and debris on the movement of the scraper 322 is reduced. At the same time, since the cutting of packaging boxes usually involves cutting the scraps of the packaging boxes, the central laser cutting head will not cut the strip-shaped opening. When the packaging box moves onto the cutting table 320, the strip-shaped opening will be covered to reduce the contact between the debris generated during the cutting process and the lower surface of the cutting table 320. Meanwhile, the lower part of the conveyor belt 330 and the lower part of the cutting table 320 are isolated by a baffle.
[0036] like Figure 1 and Figure 2 As shown, two guide strips 220 are provided between the upper conveyor roller 210 and the lower conveyor roller 200. One end of the guide strip 220 is curved. The two guide strips 220 are arranged opposite each other. The guide strips 220 are fixedly connected to the inner walls of both sides of the frame 100. Gears are fixedly connected to one end of the upper conveyor roller 210 and the lower conveyor roller 200. Both sets of gears are connected by auxiliary gears. The number of upper conveyor rollers 210 is less than the number of lower conveyor rollers 200. Multiple upper conveyor rollers 210 are arranged in the middle position of multiple lower conveyor rollers 200. The frame 100 is provided with protective shells at the positions of multiple gears. Multiple gears are arranged inside the protective shells.
[0037] In this embodiment, an auxiliary gear is interlocked between every two gears connected to the conveyor rollers. The conveyor rollers are driven by the auxiliary gears. The two sets of conveyor rollers are made of high-molecular composite material. The conveyor rollers made of this material have a low mass, thereby reducing the weight of the conveyor rollers themselves and reducing the resistance of the motor to drive multiple conveyor rollers. The distance between the upper conveyor roller 210 and the lower conveyor roller 200 is less than the thickness of the packaging box, and the two sets of conveyor rollers rotate in opposite directions.
[0038] Working principle: The slab-shaped packaging box is placed on the lower conveyor roller 200. Then the device is started, and the packaging box is transported by the lower conveyor roller 200 to the space between the lower conveyor roller 200 and the upper conveyor roller 210. At this time, the packaging box is guided by the guide bar 220 to the middle position of the lower conveyor roller 200. The packaging box is transported by the two conveyor rollers and falls onto the cutting table 320. When the packaging box falls onto the cutting table 320, the sensor 350 is triggered. After receiving the signal, the sensor 350 feeds back to the control system. The control system starts the cutting mechanism to cut the packaging box according to the programmed data.
[0039] After the packaging box is cut, the control system will activate the electric push rod 321, which will push the scraper 322 to move the packaging box and the waste generated from cutting the packaging box on the surface of the cutting table 320 towards the conveyor belt 330. Since the waste from the packaging box is usually scrap, and the usable part of the packaging box has a large area, after the packaging box comes into contact with the conveyor belt 330, the packaging box will be moved along the surface of the conveyor belt 330 by the conveyor belt 330. The scrap will fall into the collection box 340 through the gaps between the conveyor belts 330 during the movement, and then fall into the drawer 341 through the collection box 340. After processing is completed, the waste can be recycled through the drawer 341.
[0040] It should be noted that the cutting component 310, electric push rod 321, drive motor 331 and sensor 350 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the cutting component 310, electric push rod 321, drive motor 331 and sensor 350 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.
[0041] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
