Description

Technical Field

[0001] This utility model relates to the field of printing waste recycling technology, and in particular to a waste recycling device for digital printing. Background Technology

[0002] Printing waste refers to various industrial wastes generated during the printing production process, such as ink cartridges. As a printing consumable, ink cartridges need to be recycled after use, thus requiring the use of waste recycling equipment.

[0003] A search revealed a digital printing waste recycling device (publication number: CN215197391U) on the China Patent Network, comprising a crushing box and a compression box. The crushing box has a feed inlet at its top. Two parallel longitudinal cutting rollers are rotatably connected to the upper interior of the crushing box, with longitudinal cutters evenly distributed around their outer circumferences, and the longitudinal cutters of the two rollers are staggered. Two parallel transverse cutting rollers are rotatably connected to the lower interior of the crushing box, with transverse cutters evenly distributed around their outer circumferences, and the transverse cutters of the two rollers are staggered. The lower part of the crushing box is connected to the upper side of one side of the compression box via a pipe. A compression cylinder is located above the compression box, and the piston rod of the compression cylinder passes into the compression box and connects to a pressure plate. A side baffle is located above the side of the pressure plate near the pipe. The lower part of the compression box has an open structure, and a sliding drawer is laterally connected to the lower part of the compression box, driven by a pulling cylinder. Waste paper, cardboard, and other waste materials generated during digital printing are fed into the shredding chamber through the inlet. The longitudinal cutter of the longitudinal roller first performs longitudinal cutting, and then the transverse cutter of the transverse roller performs transverse cutting, thereby achieving the shredding function. The shredded waste material enters the compression chamber, and the compression cylinder compresses the waste material in the compression chamber at regular intervals. When the compression chamber is full, the pull plate is opened by pulling the cylinder to discharge and store the waste material, reducing the space occupied. At the same time, the side baffle can effectively prevent the waste material from falling from the pipe onto the top of the pressure plate during the compression process. The application uses a combination of longitudinal and transverse cutters to improve the crushing effect of waste materials. However, printing waste contains a large amount of ink, and the heavy metal compounds in this ink cannot be treated in this application. After being crushed directly by longitudinal and transverse cutters, some ink will adhere to the cutters and the inside of the device. This ink will affect the health of workers during long-term use. At the same time, the wastewater generated during the cleaning operation after waste recycling will also directly cause environmental pollution, indicating room for improvement. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a waste recycling device for digital printing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A waste recycling device for digital printing includes a recycling bin, an industrial control host on the front of the recycling bin, a fixing groove on the front of the recycling bin, a recycling frame slidably connected to the inner wall of the fixing groove, a pre-treatment component on the upper surface of the recycling bin, and a crushing component on the right side of the recycling bin. The pre-treatment component includes a positioning frame, a feeding hopper fixedly connected to the upper surface of the positioning frame, a cover plate rotatably connected to the back of the feeding hopper, a first servo motor fixedly connected to the right side of the positioning frame, a rotating shaft fixedly connected to the output end of the first servo motor, and the rotating shaft fixedly connected to the output end of the first servo motor via a coupling. A semi-circular frame rotatably connected to the inner wall of the positioning frame, a liquid storage tank and a waste liquid tank fixedly connected to the left and right sides of the recycling bin, respectively, and a slot on the right side of the waste liquid tank, with a waste liquid frame slidably connected to the inner wall of the slot.

[0006] Preferably, the position of the semicircular frame corresponds to the position of the feed hopper, and two arc-shaped baffles are fixedly connected to the inner top wall of the positioning frame. Both arc-shaped baffles overlap with the surface of the semicircular frame. Due to the blocking effect of the two arc-shaped baffles, the printing waste can fall stably into the semicircular frame and will not fall into other positions within the positioning frame.

[0007] Preferably, the right side of the positioning frame has a circular hole that matches the rotating shaft. The end of the rotating shaft away from the first servo motor is fixedly connected to the right side of the semi-circular frame. The first servo motor can drive the semi-circular frame to rotate inside the positioning frame through the rotating shaft, so that the printing waste inside the semi-circular frame falls into the recycling bin.

[0008] Preferably, a delivery pump is fixedly connected to the upper surface of the storage tank. The input end of the delivery pump is connected to the interior of the storage tank, and the output end of the delivery pump is connected to a first flexible hose. A second flexible hose is connected to the upper surface of the waste liquid tank, and a solenoid valve is installed on the surface of the second flexible hose. The delivery pump can deliver Fenton reagent in the storage tank to the semi-circular frame. Fenton reagent can oxidize and decompose the heavy metal compounds in the ink into harmless substances, ensuring that no environmental pollution is caused during the recycling process.

[0009] Preferably, the end of the first hose away from the delivery pump is fixedly connected to the left side of the semicircular frame, and the end of the second hose away from the waste liquid tank is fixedly connected to the right side of the semicircular frame. During the rotation of the semicircular frame, since both the first hose and the second hose are made of flexible materials, the first hose and the second hose will not break or detach, and the normal pretreatment process will not be affected.

[0010] Preferably, the crushing assembly includes two second servo motors. The output ends of the two second servo motors extend into the interior of the recycling bin and are fixedly connected to connecting shafts. The connecting shafts are fixedly connected to the output ends of the second servo motors via couplings. The ends of the two connecting shafts away from the second servo motors are rotatably connected to the left inner wall of the recycling bin. Crushing rollers are fixedly connected to the surfaces of the two connecting shafts. After the printing waste falls from the positioning frame, the second servo motors can drive the crushing rollers to rotate via the connecting shafts, thereby crushing the printing waste.

[0011] It should be noted that the first servo motor, the delivery pump, the solenoid valve, and the second servo motor are all electrically connected to the industrial control host via wires. The industrial control host can control the start and stop operations of each electrical device.

[0012] The beneficial effects of this utility model are as follows: 1. By combining the pretreatment and crushing components, the Fenton reagent in the storage tank can be transported to the semi-circular frame by the transfer pump to soak the printing waste. This allows the heavy metal compounds in the ink on the printing waste to be oxidized and decomposed into harmless substances. This prevents the ink from contaminating the entire recycling device during the recycling process and also avoids environmental pollution caused by wastewater discharge. This not only improves the health protection of the staff but also enhances the recycling effect of printing waste. 2. Through the coordinated arrangement of the first servo motor, the rotating shaft, the first flexible hose, and the second flexible hose, during the rotation of the semi-circular frame driven by the first servo motor through the rotating shaft, the flexibility of the first flexible hose and the second flexible hose ensures that the first flexible hose and the second flexible hose will not detach from the semi-circular frame and break, thus not affecting the normal pre-processing of printing waste. Furthermore, the two arc-shaped baffles ensure that the printing waste can fall stably into the semi-circular frame. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-4 Example 1: A waste recycling device for digital printing includes a recycling box 1. An industrial control host 2 is provided on the front of the recycling box 1. A fixing groove is opened on the front of the recycling box 1. A recycling frame 3 is slidably connected to the inner wall of the fixing groove. A pretreatment component 4 is provided on the upper surface of the recycling box 1. A crushing component 5 is provided on the right side of the recycling box 1. The pretreatment component 4 includes a positioning frame 401. A feeding hopper 402 is fixedly connected to the upper surface of the positioning frame 401. A cover plate 403 is rotatably connected to the back of the feeding hopper 402. A first servo motor 404 is fixedly connected to the right side of the positioning frame 401. A rotating shaft 405 is fixedly connected to the output end of the first servo motor 404. A semi-circular frame 406 is rotatably connected to the inner wall of the positioning frame 401. A liquid storage tank 407 and a waste liquid tank 408 are fixedly connected to the left and right sides of the recycling box 1, respectively. A slot is opened on the right side of the waste liquid tank 408. A waste liquid frame 409 is slidably connected to the inner wall of the slot. The position of the semicircular frame 406 corresponds to the position of the feed hopper 402. Two arc-shaped baffles 410 are fixedly connected to the inner top wall of the positioning frame 401. Both arc-shaped baffles 410 overlap with the surface of the semicircular frame 406. A circular hole adapted to the rotating shaft 405 is opened on the right side of the positioning frame 401. The end of the rotating shaft 405 away from the first servo motor 404 is fixedly connected to the right side of the semicircular frame 406. A delivery pump 411 is fixedly connected to the upper surface of the storage tank 407. The input end of the delivery pump 411 is connected to the inside of the storage tank 407. The output end of the delivery pump 411 is connected to the first hose 412. The upper surface of the waste tank 408 is connected to the second hose 413. A solenoid valve 414 is provided on the surface of the second hose 413. The end of the first hose 412 away from the delivery pump 411 is fixedly connected to the left side of the semicircular frame 406. The end of the second hose 413 away from the waste tank 408 is fixedly connected to the right side of the semicircular frame 406. The printing waste to be recycled is poured into the positioning frame 401 through the feed hopper 402. Due to the blocking effect of the two arc-shaped baffles 410, the printing waste can fall stably into the semi-circular frame 406. At this time, the cover plate 403 is closed, and the delivery pump 411 is turned on through the industrial control host 2. The delivery pump 411 can deliver the Fenton reagent in the storage tank 407 into the semi-circular frame 406 through the first hose 412. The reagent can soak the printing waste, thereby oxidizing and decomposing the heavy metal compounds in the ink on the printing waste, and allowing... It becomes a harmless substance, which can avoid environmental pollution when wastewater is discharged, and also prevent ink from staining the entire recycling device. After the pretreatment is completed, the solenoid valve 414 is opened to allow the wastewater to enter the waste liquid frame 409 in the waste liquid tank 408 through the second hose 413. At this time, the first servo motor 404 is turned on. The first servo motor 404 can drive the semi-circular frame 406 to rotate through the rotating shaft 405, so that the processed printing waste in the semi-circular frame 406 can fall into the recycling box 1 and be crushed by the crushing component 5. Due to the flexibility of the first hose 412 and the second hose 413, the semi-circular frame 406 will not cause the first hose 412 and the second hose 413 to break or detach during rotation, thus not affecting the normal pretreatment process.

[0017] Example 2: The crushing component 5 includes two second servo motors 501. The output ends of the two second servo motors 501 extend into the interior of the recycling box 1 and are fixedly connected to a connecting shaft 502. The ends of the two connecting shafts 502 away from the second servo motors 501 are rotatably connected to the left inner wall of the recycling box 1, and crushing rollers 503 are fixedly connected to the surfaces of the two connecting shafts 502. The pre-treated printing waste falls into the recycling bin 1 and rests between the two crushing rollers 503. At this time, the industrial control host 2 turns on the two second servo motors 501. The two second servo motors 501 can drive the two crushing rollers 503 to rotate in the middle direction through the two connecting shafts 502, thereby crushing the printing waste. After crushing, the printing waste can automatically fall into the recycling box 3, which is convenient for centralized collection of the crushed printing waste.

[0018] Working principle: First, the printing waste to be recycled is poured into the semi-circular frame 406 through the feed hopper 402. Due to the blocking effect of the two arc-shaped baffles 410, the waste will not fall into other positions in the positioning frame 401 except for the semi-circular frame 406. After pouring, the cover plate 403 is closed, and the transfer pump 411 is turned on through the industrial control host 2. The transfer pump 411 can transport the Fenton reagent in the storage tank 407 to the semi-circular frame 406 through the first hose 412. The Fenton reagent can oxidize and decompose the heavy metal compounds in the ink on the printing waste, turning the heavy metal compounds in the ink into harmless substances. This ensures that the wastewater discharge will not cause environmental pollution and that the ink will not contaminate the entire recycling device. After the printing waste is pre-treated, the solenoid valve 414 is turned on through the industrial control host 2. After the solenoid valve 414 is turned on, the semi-circular frame 406... The wastewater inside can enter the waste liquid frame 409 in the waste liquid tank 408 through the second hose 413. After the wastewater is discharged, the first servo motor 404 is started. The first servo motor 404 can drive the semi-circular frame 406 to rotate in the positioning frame 401 through the rotating shaft 405. Due to the flexibility of the first hose 412 and the second hose 413, the semi-circular frame 406 will not cause the first hose 412 and the second hose 413 to detach or break after rotation. After rotation, the printing waste in the semi-circular frame 406 can fall down into the recycling box 1 and rest on the surface of the two crushing rollers 503. At this time, the two second servo motors 501 can drive the two crushing rollers 503 to rotate in the middle direction through the two connecting shafts 502, thereby crushing the printing waste. After crushing, the waste falls into the recycling frame 3 at the bottom, realizing the entire recycling operation.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
