Description

Technical Field

[0001] This utility model relates to the field of crushing device technology, and in particular to a crushing device for corrugated cardboard box scraps. Background Technology

[0002] Corrugated cardboard scrap shredding refers to the process of shredding the corrugated cardboard scraps generated after cutting during the production or use of corrugated cardboard boxes. This process aims to reuse these scraps, thereby reducing resource waste and improving resource utilization.

[0003] Crushing devices play an important role in crushing corrugated cardboard scraps, solving the problem of crushing and reusing corrugated paper scraps generated during the corrugated paper production process.

[0004] Currently, shredding equipment is only suitable for processing dry corrugated cardboard scraps. However, some scraps are prone to absorbing moisture during storage. Damp materials are susceptible to adhesion and equipment overload during shredding, affecting shredding efficiency and normal equipment operation.

[0005] To address this, we propose a device for crushing corrugated cardboard box scraps. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a corrugated cardboard box scrap crushing device.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a corrugated cardboard box scrap crushing device, comprising a frame, a housing fixedly connected to the top of the frame, and a crushing assembly installed in the housing;

[0008] A material hood is fixedly connected to the top of the shell, and the material hood has a fixedly connected outer shell at its feed end. A mesh belt conveyor that extends through to the other side is fixedly connected to one side of the outer surface of the outer shell, and the body of the mesh belt conveyor is fixedly connected to the outer shell. A transmission component is installed between the main shaft of the mesh belt conveyor and the crushing component.

[0009] The mesh belt conveyor has multiple lifting baffles uniformly and fixedly connected to the mesh belt surface, and the outer wall of the lifting baffles away from the mesh belt conveyor is in contact with the inner wall of the outer shell.

[0010] The mesh belt conveyor has two side guards symmetrically attached to its mesh belt surface, and the side guards are attached to the side wall of the adjacent lifting partition and fixedly connected to the inner wall of the outer shell.

[0011] The mesh belt conveyor is equipped with a hot air supply component, and the air outlet of the hot air supply component is located on one side of the side baffle.

[0012] The outer surface of the shell is connected to a feed hopper at the bottom of one side of the side guard.

[0013] Furthermore, a discharge hopper is fixedly connected to one side of the bottom of the shell, providing a centralized and smooth discharge channel for the crushed material.

[0014] Furthermore, the crushing assembly includes a geared motor, two crushing rollers, and two meshing gears. The geared motor is fixedly mounted on the top of the frame and located on one side of the housing. Both crushing rollers are disposed inside the housing, and the mounting shafts at both ends of the two crushing rollers are disposed through the housing and rotatably connected to the housing. The output shaft of the geared motor is fixedly connected to the adjacent crushing roller, and the two gears are disposed on the other side of the housing and fixedly connected to the adjacent crushing rollers respectively. The high-speed opposite rotation of the two crushing rollers is achieved by driving the two rollers with a single geared motor and utilizing gear meshing.

[0015] Furthermore, an exhaust pipe is fixedly connected to the top side of the outer casing, which can promptly discharge the hot and humid air generated during the drying process.

[0016] Furthermore, the transmission assembly includes a small pulley and a large pulley, with the small pulley fixedly connected to an adjacent gear and the large pulley fixedly connected to the main shaft of the mesh belt conveyor. A transmission belt is tensioned and sleeved between the small pulley and the large pulley, and belt drive is used to achieve speed reduction and torque increase, so that the mesh belt conveyor can obtain a stable conveying speed suitable for the material drying time.

[0017] Furthermore, the hot air supply component includes an industrial hot air blower, which is fixedly installed on one side of the outer wall of the mesh belt conveyor. The output end of the industrial hot air blower is fixedly connected to a fixed pipe, which extends through the outer wall of the mesh belt conveyor and into the interior, and is fixedly connected to a hollow air distribution plate. The hot air source is directly integrated into the conveying mechanism, resulting in a compact structure and reduced heat loss from the pipeline.

[0018] Furthermore, the outer surface of the air distribution hollow plate is evenly provided with multiple air holes on one side of the side baffle, so that hot air is blown toward the material in multiple dispersed and uniform airflow forms, avoiding local overheating or drying dead corners.

[0019] The beneficial effects of this utility model are:

[0020] In use, this utility model, by setting up a mesh belt conveyor with lifting baffles and side guards in conjunction with a hot air supply component, conveys the scrap material before crushing it and uses hot air to fully preheat and dry it, effectively removing the moisture from the material and making it dry. This greatly improves the crushing efficiency and output, avoids the problem of damp material adhering to the crushing roller or clogging the equipment, which would cause the motor to overload, and significantly enhances the stability and reliability of the equipment operation.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-4 As shown, a corrugated cardboard box scrap crushing device is disclosed, including a frame 1, which serves as the basic support structure of the entire device. It is usually welded from Q235B carbon steel profiles. A shell 2 is fixedly connected to the top of the frame 1, and a discharge hopper 15 is fixedly connected to one side of the bottom of the shell 2. The outlet diameter of the discharge hopper 15 should be large enough and designed with an inclination angle of more than 60° to ensure that the crushed material is discharged smoothly and quickly by gravity.

[0030] The housing 2 is equipped with a crushing assembly, which includes a geared motor 14, two crushing rollers 16, and two meshing gears 11. The geared motor 14 is fixedly mounted on the top of the frame 1 and located on one side of the housing 2. The two crushing rollers 16 are both located inside the housing 2. The mounting shafts at both ends of the two crushing rollers 16 are set through the housing 2 and are rotatably connected to the housing 2. The output shaft of the geared motor 14 is fixedly connected to the adjacent crushing roller 16. The two gears 11 are located on the other side of the housing 2 and are fixedly connected to the adjacent crushing rollers 16 respectively. The mounting shafts of the crushing rollers 16 are rotatably connected to the housing 2 through bearing seats. The bearing seat body is fixed to the housing 2. The inner ring of the bearing inside the bearing seat is fixedly sleeved on the mounting shaft. A sealing sleeve is sealed on the outer surface of the mounting shaft. The sealing sleeve is located between the two bearing seats and is fixed to the housing 2 to ensure the sealing of the connection.

[0031] The top of the housing 2 is fixedly connected to the material hood 3, the material hood 3 is fixedly connected to the outer shell 4, and the top side of the outer shell 4 is fixedly connected to the exhaust pipe 12. The outer shell 4 adopts a heat preservation design to reduce heat loss. The top of the exhaust pipe 12 is equipped with a flange interface for connecting to an external exhaust pipe.

[0032] A mesh belt conveyor 6 is fixedly connected to one side of the outer surface of the outer shell 4, extending to the other side. The body of the mesh belt conveyor 6 is fixedly connected to the outer shell 4. A transmission component is installed between the main shaft of the mesh belt conveyor 6 and the crushing component. The transmission component includes a small pulley 10 and a large pulley 5. The small pulley 10 is fixedly connected to the adjacent gear 11, and the large pulley 5 is fixedly connected to the main shaft of the mesh belt conveyor 6. A transmission belt 9 is tensioned and sleeved between the small pulley 10 and the large pulley 5. The mesh belt conveyor 6 used in this application is not matched with a motor and mainly relies on the rotating component to drive the operation. The mesh belt conveyor 6 adopts a small hole design on the mesh belt, making it difficult for scrap materials to pass through the holes on the mesh belt.

[0033] Multiple lifting baffles 17 are uniformly fixedly connected to the mesh belt surface of the mesh belt conveyor 6, and the outer wall of the lifting baffle 17 away from the mesh belt conveyor 6 is in contact with the inner wall of the outer shell 4. Two side baffles 18 are symmetrically attached to the mesh belt surface of the mesh belt conveyor 6, and the side baffles 18 are in contact with the side wall of the adjacent lifting baffle 17 and are fixedly connected to the inner wall of the outer shell 4.

[0034] The mesh belt conveyor 6 is equipped with a hot air supply component, and the air outlet of the hot air supply component is located on one side of the side baffle 18. The hot air supply component includes an industrial hot air blower 7, which is fixedly installed on one side of the outer wall of the mesh belt conveyor 6. The output end of the industrial hot air blower 7 is fixedly connected to a fixed pipe 13, which extends through the outer wall of the mesh belt conveyor 6 and into the interior, and is fixedly connected to a hollow air distribution plate 19. The outer surface of the hollow air distribution plate 19 is evenly provided with multiple air holes 20 on one side of the side baffle 18. The industrial hot air blower 7 consists of three main parts: a blower, a heater, and a control circuit.

[0035] The outer surface of the housing 2 is located on the bottom of the side guard 18 and is connected to the feed hopper 8.

[0036] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the geared motor 14 and the industrial hot air blower 7 to facilitate overall control. The specific data analysis and processing involved to further realize the control function are methods that can be implemented by those skilled in the art based on common knowledge. These methods are not within the scope of this solution. The above description is only to illustrate the beneficial effects that can be achieved by this hardware structure improvement in conjunction with common knowledge.

[0037] Working principle: Power is provided by a geared motor 14, which drives one crushing roller 16 to rotate and, through two meshing gears 11, drives another crushing roller 16 to rotate in the opposite direction. Simultaneously, a small pulley 10 fixed to the shaft of the gear 11 drives a large pulley 5 fixed to the main shaft of the mesh belt conveyor 6 via a transmission belt 9, thus driving the mesh belt conveyor 6. Damp corrugated paper scraps fall from the feed hopper 8 onto the mesh belt of the mesh belt conveyor 6. The lifting baffle 17 on the mesh belt, together with the side guards 18 on both sides, forms a closed conveying space. During the conveying process, hot air generated by the industrial hot air blower 7 is conveyed through the fixed pipe 13 to the air distribution hollow plate 19 and evenly blown out through the air holes 20 on its surface, fully preheating and drying the material. After drying, the material is conveyed to the top and falls, guided by the material cover 3 into the crushing chamber inside the housing 2, where it is crushed by two counter-rotating crushing rollers 16. Finally, the crushed material is discharged from the discharge hopper 15. The hot and humid airflow generated during the drying process is discharged through the exhaust pipe 12 at the top of the outer casing 4.
