Description

Technical Field

[0001] The present invention belongs to the technical field of carton processing, and in particular relates to a device and method for recycling and packaging scraps from carton processing. Background Art

[0002] In the process of carton processing, some paper scraps will be generated. Currently, there are two main methods for dealing with scraps: landfill and incineration. However, both methods have obvious disadvantages. Landfill will occupy a large amount of land resources, and the scraps are difficult to degrade in the soil, which may cause soil pollution. Incineration will produce a large amount of exhaust gas, which contains harmful substances and has a serious impact on air quality. Therefore, a more environmentally friendly and efficient method for dealing with paper scraps is needed.

[0003] In recent years, with the improvement of environmental awareness and the advancement of technology, some paper / carton production companies have begun to try to recycle and reuse scraps. However, most of the existing recycling devices have some problems, such as low recycling efficiency, high processing costs, and complicated operations. In particular, in the packaging process of scraps, a large amount of labor and time are often required, resulting in low recycling efficiency. In addition, when adding waste paper scraps to the recycling device, it is impossible to classify paper scraps of different sizes. Paper scraps of different sizes are made of different materials. Since different materials have different final processing shapes, the remaining scraps are also of different sizes. They will accumulate together when collected. Recycling and packaging them together will require separation again when reused, wasting manpower and financial resources.

[0004] It is necessary to enable the device to separate paper scraps of two different sizes corresponding to different materials when recycling them, so that there will be no paper scraps of other materials in the scrap pile after the device completes the recycling and packaging of the paper scraps.

[0015] The present invention also provides a method for recycling and packaging scraps based on carton production, comprising the following steps: S1. The collected scraps are guided to the top of the screening plate and poured in. Since the scraps of two different materials are cut into different sizes, the small-shaped paper scraps can pass through the screening holes and enter the interior of the shell. The servo motor is started to drive the first crushing drum to rotate, and the first crushing drum drives the first transmission gear to rotate, so that the first transmission gear drives the second crushing drum to rotate due to its own shape when rotating, and then drives the second transmission gear to rotate, so that the first crushing drum and the second crushing drum rotate in opposite directions, thereby crushing the paper scraps collected from the top, and the first crushing drum and the two sets of eccentric wheel rods are connected by a meshing belt. The rotation of the first crushing drum drives the meshing belt to move, and then drives the two sets of eccentric wheel rods to rotate through the meshing belt, so that the eccentric wheel rods continuously contact and separate from the screening plate due to their own shape, causing the screening plate to vibrate, thereby improving the top to screen the two different-material and different-sized paper scraps, so that the device only recycles and packs paper scraps of one material; S2, the first crushing drum and the second crushing drum crush the paper scraps, and then they fall into the interior of the extrusion trough through the guidance of the guide slope. At this time, the front baffle and the rear baffle are in a closed state. When the paper scraps accumulated in the extrusion trough reach a specified amount, the hydraulic cylinder is started, and the hydraulic cylinder drives the extrusion plate to press down, so that the extrusion plate squeezes the paper scraps into paper blocks when pressing down. After the extrusion operation is completed, the extrusion plate is reset, and the connection between the front baffle and the rear baffle and the shell is untied. The cylinder is started, the cylinder contracts, and the front baffle and the rear baffle are pulled apart. At this time, the paper blocks that have been extruded can be taken out for stacking; S3. After the material is taken out, the cylinder is started, and the cylinder is extended and retracted to close the front baffle and the rear baffle, and the front baffle and the rear baffle are manually connected to the shell to prevent the front baffle and the rear baffle from opening during the extrusion process to affect the efficiency of block formation; S4. After the paper scraps of one material are recycled and packaged, the screening plate is rotated so that the two sets of limit grooves on the screening plate are aligned with the position of the mounting seat, and the pressing plate is pressed to drive the connecting rod and the mounting seat to move toward the limit groove, so that when the limit plate moves, it contacts the limit block and squeezes the limit block inward to pass through. After the limit plate passes, the second return spring resets the limit block so that the limit block limits the limit plate, thereby fixing the position of the screening plate. At this time, another material after screening can be recycled and packaged, and the screen plate is prevented from moving around and generating noise during recycling and packaging. S5. When screening, recycling and packaging are needed again, continue to press the pressing plate. After the movable disk moves, it will contact the limit block and can squeeze the limit block and pass itself. After the movable disk passes, the second return spring will reset the limit block and can lift the movable disk through the shape of the limit block, so that the movable disk and the limit disk fit together. At this time, let go, and the restoring force of the first return spring can pull the mounting seat and the components installed on the mounting seat outward, thereby driving the movable disk and the limit disk out of the inside of the limit groove, and then flipping the screening plate to the top of the device for shaking screening.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention arranges a screening plate, screening holes, meshing belts and other structures so that the device can, when recycling and packaging paper scraps of two different materials and different sizes, screen the paper scraps of one material according to the shape of the screening holes, so that they fall to the bottom and are only crushed and recycled and packaged. After completing the recycling and packaging of the paper scraps of one material, the screening plate is flipped over and the paper scraps of the other material are added for recycling and packaging, thereby achieving the purpose of facilitating the device to recycle and package paper scraps of two different materials and different sizes.

[0017] The present invention arranges a pressing plate, a connecting rod, a sleeve and other structures to enable the device to fix the position of the screen plate, thereby preventing the vibration generated by the entire device from driving the movable connected screen plate to move and generate noise when recycling and packaging paper scraps of another material. In addition, by flipping the screen plate, paper scraps of another material can be quickly added to the device for recycling and packaging, thereby achieving the purpose of facilitating noise reduction of the device and being able to recycle and package paper scraps of another material.

[0018] The present invention arranges the coordination of structures such as the front baffle, the cylinder, and the rear baffle so that the device can start the cylinder, which contracts and then pulls the front baffle and the rear baffle apart. At this time, the paper blocks that have been extruded can be taken out for stacking. After the material is taken out, the cylinder is started, and the cylinder is extended and retracted to close the front baffle and the rear baffle, and the front baffle and the rear baffle are manually connected to the shell to prevent the front baffle and the rear baffle from opening during the extrusion process and affecting the efficiency of block formation, thereby achieving the purpose of facilitating the removal of the packaged scraps.

[0024] The above scheme is adopted: the first crushing drum 8 and the second crushing drum 10 crush the paper scraps, and then they fall into the interior of the extrusion groove 15 through the guidance of the guide slope 14. At this time, the front baffle 2 and the rear baffle 4 are in a closed state. When the paper scraps accumulated in the extrusion groove 15 reach the specified amount, the hydraulic cylinder 5 is started, and the hydraulic cylinder 5 drives the extrusion plate 6 to press down, so that the extrusion plate 6 squeezes the paper scraps into paper blocks when pressing down. After the extrusion operation is completed, the extrusion plate 6 is reset, and the connection between the front baffle 2 and the rear baffle 4 and the shell 1 is untied, and the cylinder 3 is started.

[0026] The above scheme is adopted: the connection between the first crushing cylinder 8, the eccentric wheel rod 1204 and the meshing belt 1203 is equivalent to a synchronous belt drive. In order to ensure that one belt drives multiple driven components synchronously, a guide wheel or a tensioner is set between the two adjacent eccentric wheel rods 1204 to increase the friction wrap angle. The setting of the guide wheel or the tensioner is a conventional technical means for those skilled in the art, and its principle and assembly relationship will not be described here. The shaking of the eccentric wheel rod 1204 can quickly screen the two scraps, so that the device can classify and recycle a type of paper scraps and ensure the quality of the final extruded paper block.

[0027] Example 3 like Figures 1 to 4 、 Figure 7 and Figure 8 As shown, this embodiment three makes the following improvements on the basis of embodiment one and embodiment two. Specifically, the limiting mechanism 13 includes a pressing plate 1301, a connecting rod 1302 and a sleeve disc 1303. The connecting rod 1302 is movably connected to the inside of the shell 1. The pressing plate 1301 is fixed to one end of the connecting rod 1302, and the sleeve disc 1303 is fixed to the outside of the connecting rod 1302. The outside of the connecting rod 1302 is sleeved with a first return spring 1304. Two groups of connecting rods 1302 are provided. The connecting rods 1302 are symmetrically distributed about the central axis of the pressing plate 1301. The diameter of the sleeve disc 1303 is larger than the diameter of the connecting rod 1302. The first return spring 1304 is used to squeeze the sleeve disc 1303 and the connecting rod 1302, and keep them moving in the opposite direction of the screening plate 1201.

[0028] like Figures 1 to 4 、 Figure 7 and Figure 8As shown, one end of the connecting rod 1302 is fixed with a mounting seat 1305, the outside of the mounting seat 1305 is fixed with a sleeve rod 1306, the outside of the sleeve rod 1306 is fixed with a limiting disk 1307, the outside of the sleeve rod 1306 is sleeved with a movable disk 1308, the inner wall of the movable disk 1308 is close to the outer wall of the sleeve rod 1306, the movable disk 1308 and the sleeve rod 1306 are slidably connected, and the contact surface diameter of the movable disk 1308 and the limiting disk 1307 is larger than the diameter of the limiting disk 1307.

[0029] like Figures 1 to 4 、 Figure 7 and Figure 8 As shown, a limiting groove 1309 is provided on the outside of the screening plate 1201, and a limiting rod 1310 is movably connected to the inside of the screening plate 1201. The outside of the limiting rod 1310 is provided with a second return spring 1311, and a limiting block 1312 is fixed on the outside of the limiting rod 1310. The limiting rod 1310 is slidably connected to the inside of the screening plate 1201, and the second return spring 1311 is used to squeeze the limiting rod 1310 and keep it moving toward the center of the limiting groove 1309. The limiting rod 1310, the second return spring 1311 and the limiting block 1312 are provided with two groups that are symmetrically distributed about the central axis of the limiting groove 1309.

[0030] The above solution is adopted: the position of the screen plate 1201 is fixed by the limit plate 1307 to prevent the vibration generated by the entire device from driving the movable connected screen plate 1201 to move and generate noise when recycling and packaging paper scraps of another material, and by flipping the screen plate 1201, paper scraps of another material can be quickly added to the device for recycling and packaging.

[0031] The present invention also provides a method for recycling and packaging scraps based on carton production, comprising the following steps: S1. The collected scraps are directed to the top of the screening plate 1201 and poured in. Since the scraps of two different materials are cut into different sizes, the small-shaped paper scraps can pass through the screening holes 1202 and enter the interior of the shell 1. The servo motor 7 is started to drive the first crushing drum 8 to rotate, and the first crushing drum 8 drives the first transmission gear 9 to rotate, so that the first transmission gear 9 drives the second crushing drum 10 to rotate due to its own shape when rotating, and then drives the second transmission gear 11 to rotate, so that the first crushing drum 8 and the second crushing drum 10 rotate in opposite directions, thereby collecting the scraps at the top. The collected paper scraps are crushed, and the first crushing drum 8 and the two sets of eccentric wheel rods 1204 are connected by the meshing belt 1203. The first crushing drum 8 rotates to drive the meshing belt 1203 to move, and then the meshing belt 1203 drives the two sets of eccentric wheel rods 1204 to rotate, so that the eccentric wheel rods 1204 continuously contact and separate from the screening plate 1201 through their own shape, causing the screening plate 1201 to shake, thereby raising the top end to screen the two different materials and different sizes of paper scraps, so that the device only recycles and packs paper scraps of one material; S2, the first crushing drum 8 and the second crushing drum 10 crush the paper scraps, and then they fall into the inside of the extrusion groove 15 through the guidance of the guide slope 14. At this time, the front baffle 2 and the rear baffle 4 are in the closed state. When the paper scraps accumulated in the extrusion groove 15 reach the specified amount, the hydraulic cylinder 5 is started, and the hydraulic cylinder 5 drives the extrusion plate 6 to press down, so that the extrusion plate 6 squeezes the paper scraps into paper blocks when pressing down. After the extrusion operation is completed, the extrusion plate 6 is reset, and the connection between the front baffle 2 and the rear baffle 4 and the housing 1 is untied, and the cylinder 3 is started. The cylinder 3 contracts, and then the front baffle 2 and the rear baffle 4 are pulled apart. At this time, the paper blocks after extrusion can be taken out for stacking; S3. After the material is taken out, the cylinder 3 is started, and the cylinder 3 is extended and retracted to close the front baffle 2 and the rear baffle 4, and the front baffle 2 and the rear baffle 4 are manually connected to the shell 1 to prevent the front baffle 2 and the rear baffle 4 from opening during the extrusion process to affect the efficiency of block formation; S4. After the paper scraps of one material are recycled and packaged, the screening plate 1201 is rotated so that the two sets of limit grooves 1309 opened on the screening plate 1201 are aligned with the position of the mounting seat 1305, and the pressing plate 1301 is pressed to drive the connecting rod 1302 and the mounting seat 1305 to move toward the limit groove 1309, so that the limit plate 1307 contacts the limit block 1312 when moving, and squeezes the limit block 1312 inward and passes itself. After the limit plate 1307 passes, the second return spring 1311 resets the limit block 1312, so that the limit block 1312 limits the limit plate 1307, thereby fixing the position of the screening plate 1201. At this time, the other material after screening can be recycled and packaged, and the screening plate 1201 is prevented from moving around and generating noise during recycling and packaging. S5. When screening, recycling and packaging are needed again, continue to press the pressing plate 1301. After moving, the movable disk 1308 contacts the limit block 1312 and can also squeeze the limit block 1312 and pass itself. After the movable disk 1308 passes, the second return spring 1311 resets the limit block 1312 and can lift the movable disk 1308 through the shape of the limit block 1312, so that the movable disk 1308 and the limit disk 1307 fit together. At this time, let go, and the restoring force of the first return spring 1304 can pull the mounting seat 1305 and the components mounted on the mounting seat 1305 outward, thereby driving the movable disk 1308 and the limit disk 1307 out of the inside of the limit groove 1309, and then flipping the screening plate 1201 to the top of the device for shaking screening.

10. A method for recycling and packaging scraps based on carton processing, using a carton processing scrap recycling and packaging device as described in claims 1-9, characterized in that: The following steps are involved: S1. The collected scraps are directed to the top of the screening plate (1201) and poured into the screening plate. Since the scraps of two different materials are cut into different sizes, the small-shaped paper scraps can enter the interior of the housing (1) through the screening holes (1202). The servo motor (7) is started to drive the first crushing cylinder (8) to rotate, and the first transmission gear (9) is driven to rotate through the first crushing cylinder (8), so that the first transmission gear (9) drives the second crushing cylinder (10) to rotate due to its own shape, and then drives the second transmission gear (11) to rotate, so that the first crushing cylinder (8) and the second crushing cylinder (10) rotate in opposite directions, thereby contacting the top. The paper scraps collected at the end are crushed, and the first crushing cylinder (8) and the two sets of eccentric wheel rods (1204) are connected via a meshing belt (1203). The first crushing cylinder (8) rotates to drive the meshing belt (1203) to move, and then the two sets of eccentric wheel rods (1204) are driven to rotate via the meshing belt (1203), so that the eccentric wheel rods (1204) continuously contact and separate from the screening plate (1201) through their own shapes, causing the screening plate (1201) to vibrate, thereby raising the top end to screen the paper scraps of two different materials and different sizes, so that the device only recycles and packs the paper scraps of one material; S2, the first crushing cylinder (8) and the second crushing cylinder (10) crush the paper scraps, and then the scraps are guided by the guide slope (14) into the interior of the extrusion groove (15). At this time, the front baffle plate (2) and the rear baffle plate (4) are in a closed state. When the paper scraps accumulated in the extrusion groove (15) reach a specified amount, the hydraulic cylinder (5) is started, and the hydraulic cylinder (5) drives the extrusion plate (6) to press down, so that the extrusion plate (6) squeezes the paper scraps into paper blocks when pressing down. After the extrusion operation is completed, the extrusion plate (6) is reset, and the connection between the front baffle plate (2) and the rear baffle plate (4) and the housing (1) is released at the same time, and the cylinder (3) is started. The cylinder (3) is contracted, and the front baffle plate (2) and the rear baffle plate (4) are pulled apart. At this time, the paper blocks after the extrusion process can be taken out for stacking; S3, after the material is taken out, the cylinder (3) is started, the cylinder (3) closes the front baffle (2) and the rear baffle (4), and the front baffle (2) and the rear baffle (4) are manually connected to the housing (1) to prevent the front baffle (2) and the rear baffle (4) from being opened during the extrusion process to affect the efficiency of block formation; S4. After the recycling and packaging of paper scraps of a material is completed, the screening plate (1201) is rotated so that the two sets of limit grooves (1309) provided on the screening plate (1201) are aligned with the position of the mounting seat (1305), and the pressing plate (1301) is pressed to drive the connection rod (1302) and the mounting seat (1305) to move toward the limit grooves (1309), so that the limit plate (1307) contacts the limit block (1312) when moving. The limiting block (1312) is then pressed inwards and allowed to pass through. After the limiting plate (1307) passes through, the second reset spring (1311) resets the limiting block (1312), so that the limiting block (1312) limits the limiting plate (1307), thereby fixing the position of the screening plate (1201). At this time, another material after screening can be recycled and packaged, and the screening plate (1201) is prevented from moving around and generating noise when the device is recycling and packaging. S5. When screening, recycling and packaging are required again, continue to press the pressing plate (1301). After the movable plate (1308) moves, it contacts the limit block (1312) and can also squeeze the limit block (1312) to allow itself to pass. After the movable plate (1308) passes, the second return spring (1311) can reset the limit block (1312) and lift the movable plate (1308) through the shape of the limit block (1312), so that the movable plate (1308) and the limit plate (1307) fit together. At this time, let go, and the restoring force of the first return spring (1304) can pull the mounting seat (1305) and the components mounted on the mounting seat (1305) outward, thereby driving the movable plate (1308) and the limit plate (1307) out of the limit groove (1309), and then flip the screening plate (1201) to the top of the device for shaking screening.
