Description

Technical Field

[0001] The present invention relates to the technical field of waste collection of die-cutting machines, and particularly to an automatic waste collection and packing device and method for die-cutting machines. Background Art

[0002] The cardboard die-cutting process is one of the key steps in industries such as packaging and printing, and is used to manufacture cartons, paper boxes, paper products, etc. of various shapes and sizes. During this process, a large amount of waste is generated, including scraps, irregular fragments, and paper scraps falling during the cutting process. The timely collection and treatment of these wastes are crucial for keeping the production line clean, improving production efficiency, and reducing production costs.

[0003] Traditional methods for handling cardboard die-cutting waste are mostly manual collection, that is, operators use tools such as brooms and dustpans to manually clean the waste scattered around the machine to a designated waste stacking area. This method is not only time-consuming and laborious, increasing the labor intensity of workers, but also inefficient and difficult to meet the needs of modern high-speed and continuous production. In addition, waste may be missed during manual collection, resulting in a dirty and messy production site and affecting the corporate image. To improve this situation, some automated or semi-automated waste collection devices have emerged on the market. These devices usually guide the waste to a centralized collection area through a waste collection trough or conveyor belt installed under the die-cutting machine.

[0004] However, these devices still have the following defects: existing devices often only stay in the waste collection stage and cannot compress the collected paper waste. Instead, they directly pack the collected paper waste. Due to the fluffy nature of the paper material, it will occupy a large amount of space, which is not conducive to resource recovery and reuse. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic waste collection and packing device and method for die-cutting machines, aiming to solve the problem that the automatic waste collection and packing device for die-cutting machines in the general technology cannot compress waste and is not convenient for waste recycling and reuse.

[0006] To achieve the above object, the present invention adopts the following technical solutions: An automatic waste collection and packing device for a die-cutting machine, including a collection box, further including a compression mechanism installed inside the collection box and sliding up and down along its height direction. A transfer box for packing and transporting the waste after compression by the compression mechanism is placed at the bottom of the collection box; the compression mechanism includes a pressing plate sliding up and down inside the collection box. An installation groove is opened inside the pressing plate, and a rotating plate is rotatably installed inside the installation groove through a connecting shaft. The end of the connecting shaft penetrates through the pressing plate and is rotatably installed with a sliding seat. A connecting seat is fixedly installed on one side of the sliding seat. The connecting seat is rotatably connected to the connecting shaft, and a reset member is fixedly installed inside the connecting seat. The reset member is fixedly connected to the connecting shaft and can drive it to reset after the connecting shaft rotates.

[0007] The beneficial effects are as follows: By installing a compression mechanism inside the collection box, opening an installation groove inside the pressing plate to rotate the rotating plate, arranging connecting shafts rotatably connected to the pressing plate at both ends of the rotating plate, setting a sliding seat at the end of the connecting shaft, and setting a connecting seat on one side of the sliding seat, and arranging a reset member fixedly connected to the connecting shaft inside the connecting seat, it is possible to facilitate the user to compress the waste into waste blocks by the compression mechanism while not affecting the entry of waste into the collection box, thereby reducing the volume of the waste and facilitating the recycling and reuse of the waste.

[0008] A further technical solution of the present invention is that support legs are fixedly installed at the four corners of the bottom of the collection box. A through groove is opened at the bottom of the collection box, and a bottom plate is rotatably installed inside the through groove. An aggregate nozzle is fixedly installed at the top of the collection box. The aggregate nozzle is used to guide the collected waste to the compression mechanism, and the waste passes through the compression mechanism and enters the inside of the collection box and falls on the bottom plate.

[0009] A further technical solution of the present invention is that two mounting plates are fixedly installed on two opposite outer sides of the collection box. Connecting rods for installing the bottom plate are rotatably installed inside the two opposite mounting plates. A first driving motor is fixedly installed at one end of each of the two connecting rods. The first driving motor is fixedly connected to the mounting plate.

[0010] The beneficial effects are as follows: The compressed waste blocks can gradually fall through the slowly opened bottom plate, which can prevent the compressed waste from falling directly and causing the waste to spread, affecting subsequent transportation and reuse.

[0011] A further technical solution of the present invention is that a first mounting seat and a second mounting seat are fixedly installed at an upper-middle position on the inner side wall of the collection box. A sliding rod is fixedly installed between the first mounting seat and the bottom wall of the collection box. Screws are rotatably installed inside both the second mounting seat and the bottom wall of the collection box. The bottom of the screw penetrates through the collection box and extends to the bottom of the collection box. A second driving motor for driving it is fixedly installed at the bottom end of the screw.

[0012] A further technical solution of the present invention is that four connecting bars are fixedly installed on the upper surface of the extrusion plate. All four connecting bars are L-shaped. Threaded sleeves are fixedly installed at the ends of two of the connecting bars, and sliding sleeves are fixedly installed at the ends of the other two connecting bars. The two threaded sleeves are respectively threadedly installed on the two screws, and the two sliding sleeves are respectively slidably installed on the two sliding rods.

[0013] A further technical solution of the present invention is that first slide rails for installing the sliding seats are installed at both ends of the inner wall of the collection box. Two second slide rails are fixedly installed on the inner bottom wall of the collection box. Both of the two second slide rails are located between the two first slide rails, and the two second slide rails are respectively close to the first slide rails at both ends.

[0014] A further technical solution of the present invention is that the second slide rail includes a first guide plate and a second guide plate. Both the first guide plate and the second guide plate have a vertical section and an inclined section.

[0015] A further technical solution of the present invention is that two oppositely arranged guide rods are fixedly installed on the outer surface of the connecting shaft. The guide rods are perpendicularly distributed to the rotating plate. During the downward movement of the extrusion plate driven by the screw, the inclined section of the first guide plate squeezes one of the guide rods to gradually rotate it from a horizontal state to a vertical state and enter between the vertical section of the first guide plate and the vertical section of the second guide plate. At this time, the rotating plate rotates from a vertical state to a horizontal state.

[0016] The beneficial effect is that by setting the first guide plate and the second guide plate with vertical sections and inclined sections, and arranging guide rods on the connecting shaft, during the downward movement of the extrusion plate, the inclined section of the first guide plate can squeeze the guide rods to rotate and drive the rotating plate to rotate from a vertical state to a horizontal state, thus preventing the rotating plate from getting stuck when compressing waste materials.

[0017] A further technical solution of the present invention is that fixed seats are installed at both ends of the bottom of the collection box. A support plate for supporting and strengthening the two bottom plates is slidably installed inside the fixed seat. Telescopic rods for driving the support plate are fixedly installed on both outer sides of the collection box.

[0018] The beneficial effects are as follows: By arranging a support plate inside the fixed seat, and the support plate is located at the joint of the two bottom plates, and an expansion rod is arranged to control the support plate, during use, the support plate can support and reinforce the joint of the two bottom plates, thereby preventing the two bottom plates from rotating due to excessive force and generating gaps, resulting in waste leakage.

[0019] An automatic waste collection and packing method for a die-cutting machine includes the following steps:

[0020] S1. Waste collection: Pour the waste into the interior of the collection box through the material collecting nozzle on the collection box;

[0021] S2. Waste compression: Press down the waste through the compression mechanism to compress it into a waste block;

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment 1

[0040] In general waste collection devices in the prior art, due to the lack of a compression function, the collected paper waste is directly packed. Due to the fluffy characteristics of paper waste, a large amount of space and containers will be wasted, which is not conducive to the recycling and reuse of paper waste.

[0041] Based on the above problems, in this embodiment, Figure 1 - Figure 3As shown in the figure, an automatic waste collection and packing device for a die-cutting machine includes a collection box 1. Inside the collection box 1, a compression mechanism 2 that slides up and down along its height direction is installed. At the four corners of the bottom of the collection box 1, support legs 11 are fixedly installed. A through groove 12 is opened at the bottom of the collection box 1. Inside the through groove 12, a bottom plate 13 is rotatably installed. The number of the bottom plates 13 is two, and the two bottom plates 13 are arranged oppositely. A transfer box 3 is also placed at the bottom of the collection box 1. Inside the transfer box 3, a packing bag is sleeved. The waste entering the inside of the collection box 1 accumulates on the upper surface of the bottom plate 13. The compression mechanism 2 moves downward to compress the waste on the bottom plate 13. After the waste is compressed, the bottom plate 13 is rotated so that the compressed waste slowly falls along with the gradually opened bottom plate 13 until it falls into the packing bag inside the transfer box 3. Then, the bottom plate 13 is flipped to reset it to continue collecting waste.

[0042] At the top of the collection box 1, an aggregate nozzle 101 is fixedly installed. The aggregate nozzle 101 is used to direct the collected waste to the compression mechanism 2. The waste passes through the compression mechanism 2 and enters the inside of the collection box 1 and falls on the bottom plate 13. At the upper-middle position of the inner side wall of the collection box 1, a first mounting seat 14 and a second mounting seat 15 are fixedly installed. Between the first mounting seat 14 and the bottom wall of the collection box 1, a sliding rod 141 is fixedly installed. Inside both the second mounting seat 15 and the bottom wall of the collection box 1, a screw rod 151 is rotatably installed. The bottom of the screw rod 151 penetrates the collection box 1 and extends to the bottom of the collection box 1. At the bottom end of the screw rod 151, a second driving motor 152 for driving it is fixedly installed. Between the two support legs 11 at one end, a reinforcing plate 111 is fixedly installed. The second driving motor 152 is installed on the reinforcing plate 111. At both ends of the inner wall of the collection box 1, a first slide rail 16 is also installed. The compression mechanism 2 is slidably installed inside the first slide rail 16, and the compression mechanism 2 is also slidably installed on the sliding rod 141 and is threadedly connected to the screw rod 151. The second driving motor 152 drives the screw rod 151 to rotate to drive the compression mechanism 2 so that the compression mechanism 2 can press down to compress the waste.

[0043] As Figure 1 - Figure 4 As shown in the figure, on both opposite outer sides of the collection box 1, two mounting plates 131 are fixedly installed. Inside both of the two opposite mounting plates 131, a connecting rod 132 is rotatably installed. The bottom plate 13 is sleeved on the connecting rod 132 and is fixedly connected to it. At one end of both of the two connecting rods 132, a first driving motor 133 is fixedly installed. The first driving motor 133 is fixedly connected to the mounting plate 131. In this embodiment, both the second driving motor 152 and the first driving motor 133 are reduction motors.

[0044] As Figure 5 - Figure 7As shown in the figure, the compression mechanism 2 includes an extrusion plate 21 for compressing waste materials. An installation groove 211 is formed inside the extrusion plate 21. The cross-section of the installation groove 211 is slightly larger than the bottom cross-section of the aggregate nozzle 101, so that the waste materials can enter the interior of the collection box 1 through the installation groove 211. Four connecting bars 212 are fixedly installed on the upper surface of the extrusion plate 21. All four connecting bars 212 are L-shaped. Threaded sleeves 213 are fixedly installed at the ends of two of the connecting bars 212, and sliding sleeves 214 are fixedly installed at the ends of the other two connecting bars 212. The two threaded sleeves 213 are respectively threadedly installed on the two screw rods 151, and the two sliding sleeves 214 are respectively slidably installed on the two sliding rods 141.

[0045] A rotating plate 22 is rotatably installed inside the installation groove 211. Both ends of the rotating plate 22 are rotatably connected to the extrusion plate 21 through connecting shafts 221. Both connecting shafts 221 penetrate through the extrusion plate 21 and extend partially outside the extrusion plate 21. Sliding seats 23 are rotatably installed at the ends of the two connecting shafts 221 extending outside. The sliding seats 23 are slidably installed inside the first slide rail 16. A connecting seat 24 is fixedly installed on one side of the sliding seat 23 where the connecting shaft 221 is installed. The connecting seat 24 is rotatably connected to the connecting shaft 221, and a reset member 241 is fixedly installed inside the connecting seat 24. The end of the reset member 241 is fixedly connected to the connecting shaft 221. In this embodiment, the reset member 241 is a coil spring. After installation, the rotating plate 22 is in a vertical state.

[0046] The extrusion plate 21 moves downward under the drive of the screw rod 151, causing the rotating plate 22 to gradually approach the waste materials at the bottom of the collection box 1. Under the downward pressure of the extrusion plate 21, the rotating plate 22 gradually becomes horizontal and blocks the installation groove 211. The rotating plate 22 continues to be pressed down, and the extrusion plate 21 and the rotating plate 22 jointly squeeze the waste materials at the bottom of the collection box 1 to compress them into a rectangular waste block. Since the rotating plate 22 is rotatably installed inside the installation groove 211, when the compression mechanism 2 is in the upper position, the rotating plate 22 is in a vertical state to facilitate the entry of waste materials. As the extrusion plate 21 is gradually pressed down, the rotating plate 22 rotates to a horizontal state to facilitate the compression of waste materials. At the same time, the rotating plate 22 rotated to the horizontal state will tighten the reset member 241 through the connecting shaft 221. After the waste materials are compressed and the extrusion plate 21 rises, the rotating plate 22 returns to the vertical state under the drive of the reset member 241.

[0047] As Figure 8As shown in the figure, the cross-section of the inner cavity of the transfer box 3 is larger than that of the waste block. At the bottom of both sides of the transfer box 3, rollers 31 for moving it are installed. At one end of the transfer box 3, a push rod 32 is installed to facilitate the user to move it. A limiting mechanism for fixing the packing bag can be set on the outer side wall of the transfer box 3 according to actual needs. After the waste block enters the packing bag, the packing bag is sealed and transported to a designated position for storage or treatment through the transfer box 3.

[0048] During use, first, the paper waste generated by the die-cutting machine processing the packaging cardboard is collected through the collecting nozzle 101. The waste collected through the collecting nozzle 101 enters the inside of the collecting box 1 through the installation groove 211 of the pressing plate 21 and falls on the bottom plate 13. When the collected waste exceeds the set value, the second driving motor 152 is started to drive the compression mechanism 2 to move downward, so that the pressing plate 21 and the rotating plate 22 press the waste on the bottom plate 13 to form a rectangular waste block. Finally, the bottom plate 13 is opened, and the waste block slowly follows the opening of the bottom plate 13 and gradually falls until it falls into the packing bag inside the transfer box 3. After the packing bag is sealed, the packing bag containing the waste block is transported to a designated position.

[0049] In this embodiment, by installing a compression mechanism 2 inside the collecting box 1, opening an installation groove 211 inside the pressing plate 21 to rotate the rotating plate 22, arranging connecting shafts 221 rotatably connected to the pressing plate 21 at both ends of the rotating plate 22, arranging sliding seats 23 at the ends of the connecting shafts 221, and arranging a connecting seat 24 on one side of the sliding seat 23, and arranging a resetting member 241 fixed to the connecting shaft 221 inside the connecting seat 24, it is possible to facilitate the user to compress the waste into a waste block through the compression mechanism 2 while not affecting the entry of the waste into the collecting box 1, thereby reducing the volume of the waste and facilitating the recycling and reuse of the waste. Embodiment 2

[0050] During the use process, it is found that the rotating plate 22 may be stuck in a vertical state when pressed down, resulting in the pressing plate 21 being unable to continue pressing down to compress the waste, affecting the waste treatment progress. Therefore, further improvements will be made on the basis of the above embodiment.

[0051] As Figure 1 - Figure 2 and Figure 9 As shown in the figure, the difference between this embodiment and Embodiment 1 is that two second slide rails 17 are fixedly installed on the inner bottom wall of the collecting box 1. Both of the two second slide rails 17 are located between the two first slide rails 16, and the two second slide rails 17 are respectively close to the first slide rails 16 at both ends.

[0052] The second slide rail 17 includes a first guide plate 171 and a second guide plate 172. Both the first guide plate 171 and the second guide plate 172 have a vertical section and an inclined section. The vertical section of the first guide plate 171 is parallel to the vertical section of the second guide plate 172 and their two ends are aligned. The inclined section of the first guide plate 171 is longer than the inclined section of the second guide plate 172. Two oppositely arranged guide rods 222 are fixedly installed on the outer surface of the connecting shaft 221. The guide rods 222 are perpendicularly distributed to the rotating plate 22. During the downward movement of the pressing plate 21 driven by the screw 151, the inclined section of the first guide plate 171 presses one of the guide rods 222 to gradually rotate it from the horizontal state to the vertical state and enter between the vertical section of the first guide plate 171 and the vertical section of the second guide plate 172. At this time, the rotating plate 22 rotates from the vertical state to the horizontal state, avoiding the problem of the rotating plate 22 being stuck in the vertical state.

[0053] In this embodiment, by providing the first guide plate 171 and the second guide plate 172 with vertical sections and inclined sections, and arranging the guide rods 222 on the connecting shaft 221, during the downward movement of the pressing plate 21, the inclined section of the first guide plate 171 can press the guide rods 222 to rotate and drive the rotating plate 22 to rotate from the vertical state to the horizontal state, thereby avoiding the rotating plate 22 from being stuck when compressing waste materials. Embodiment 3

[0054] It is also found during the use process that the bottom plate 13 is only driven by the first driving motor 133. During the downward pressing process of the compression mechanism 2, the bottom plate 13 may rotate due to excessive force, resulting in the waste materials inside the collection box 1 leaking from the gap between the two rotating bottom plates 13. Therefore, further improvements will be made on the basis of the above embodiments.

[0055] Such as Figure 10 - Figure 11 As shown, the differences between this embodiment and Embodiment 1 and Embodiment 2 are as follows: Fixed seats 18 are provided at both ends of the bottom of the collection box 1. A support plate 181 is slidably installed inside the fixed seat 18. The two support plates 181 slide relative to each other. The parts of the two support plates 181 that slide outside the fixed seat 18 are opposite to the joints of the two bottom plates 13, and the two support plates 181 are both in contact with the two bottom plates 13. Electric telescopic rods 19 are fixedly installed on the two outer sides of the collection box 1. The movable ends of the electric telescopic rods 19 are fixedly connected to the support plate 181. In this embodiment, the electric telescopic rod 19 is one of an electric telescopic rod or a pneumatic telescopic rod, so that the user can conveniently control the extension and retraction of the support plate 181 through the electric telescopic rod 19.

[0056] In this embodiment, by arranging a support plate 181 inside the fixed base 18, and the support plate 181 is located at the joint of the two base plates 13, and further arranging a telescopic rod 19 to control the support plate 181, during use, the support plate 181 can support and reinforce the joint of the two base plates 13, thereby preventing the two base plates 13 from rotating due to excessive force and generating gaps, resulting in waste leakage. Embodiment 4

[0057] As Figure 1 - Figure 11 shown, an automatic waste collection and packing method for a die-cutting machine includes the following steps:

[0058] S1. Waste collection: The waste is introduced into the interior of the collection box 1 through the collection nozzle 101 on the collection box 1 via the compression mechanism 2, and the waste is located on the base plate 13.

[0059] S2. Waste compression: The waste on the base plate 13 is compressed by the downward pressure of the compression mechanism 2 to form a waste block.

[0060] S3. Export of compressed waste: The base plate 13 is slowly opened, and the waste block gradually descends with the base plate 13 and finally falls into the packing bag inside the transfer box 3.

[0061] S4. Packing and transfer: The packing bag containing the waste block is sealed and transferred to a designated location for storage or disposal through the transfer box 3.

[0062] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
