Description

Technical Field

[0001] This utility model relates to the field of recycling technology, specifically to a recyclable device for recycled paper. Background Technology

[0002] In today's society, with the increasing awareness of environmental protection and the growing acceptance of the concept of resource recycling, the production and utilization of recycled paper has received widespread attention. The production of recycled paper not only reduces dependence on virgin timber resources and alleviates deforestation pressure, but also effectively treats waste paper, reducing environmental pollution problems caused by landfill and incineration. Therefore, developing efficient and reliable recycled paper production equipment is of significant practical importance. In the process of recycled paper production, the paper recycling device plays a crucial role. A Chinese utility model patent (publication number: CN222326211U) discloses a waste paper recycling device. Through the design of a compression device and a pushing structure, during use, the first and second electric push rods are activated. The first electric push rod drives the pressure plate downwards to compress the shredded waste paper. The push plate, pushed by the second electric push rod, pushes the compressed waste paper out of the compression box through a sealed door, reducing the environmental pollution caused by the scattered shredded waste paper. Simultaneously, the shredded waste paper is also convenient for subsequent transportation.

[0003] However, the above-mentioned device still has some shortcomings in use. Specifically, during the process of conveying shredded paper in the connecting pipe, due to the characteristics of the paper itself, such as fiber structure and irregular shape, as well as the uneven distribution of airflow in the connecting pipe, the shredded paper is prone to entanglement and aggregation near the discharge port, blocking the discharge port and hindering the normal conveying of subsequent shredded paper. Therefore, in view of the above situation, a recyclable device for recycled paper is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a recyclable device for recycled paper. Through the structural design of a cylinder, piston rod, air outlet pipe, and exhaust hood, the piston rod is driven to move downward inside the cylinder by rotation, generating airflow which is then transported through a pipe to the exhaust hood for discharge. This continuously blows air onto the discharge port of the guide pipe, which can promptly disperse the shredded paper accumulated near the discharge port, allowing the shredded paper to smoothly enter the compression box. This solves the problem that shredded paper easily entangles and gathers near the discharge port, clogging the discharge port and hindering the normal transport of subsequent shredded paper.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a recyclable device for recycled paper, including a processing box and an anti-clogging mechanism. A crushing component is provided on the top of the processing box, and a guide pipe is provided on the processing box. The anti-clogging mechanism includes a rotating rod rotating on the processing box and a cylinder fixed on the guide pipe. An eccentric wheel is fixedly connected to the rotating rod, and the rotating rod is connected to the crushing component through a belt. A circular cavity is opened at the top of the cylinder, and an air outlet is provided at the bottom. A retaining ring is fixed inside the circular cavity, and a piston rod is movable inside the circular cavity. A spring is fixed at the bottom of the piston rod, and a ring is fixed at the bottom of the spring. An air outlet pipe communicating with the air outlet is fixed at the bottom of the cylinder, and an exhaust hood is fixed inside the guide pipe at one end.

[0007] Furthermore, the feed tube has an "L"-shaped inner cavity, the top of the feed tube has an inlet that connects to the discharge port of the crushing component, and the side wall of the feed tube has a discharge port that connects to the inner cavity.

[0008] Furthermore, a guide plate is fixedly connected at an inclination inside the feed tube, and an exhaust hood is fixed to the side wall of the inner cavity, located below the guide plate.

[0009] Furthermore, a sealing rubber ring is fitted on the outer wall of the piston rod, and the piston rod is hemispherical at one end located outside the cylindrical cavity.

[0010] Furthermore, a through hole is provided on the feed tube, which is matched with the air outlet tube.

[0011] Furthermore, a collection box is provided at the bottom of the processing box, and the opening at the top of the collection box is located below the discharge port of the guide pipe.

[0012] This utility model has the following beneficial effects:

[0013] This invention utilizes a structural design consisting of a cylinder, piston rod, air outlet pipe, and exhaust hood. The piston rod moves downwards within the cylinder via rotation, generating airflow which is then transported through a pipe to the exhaust hood for discharge. This continuous blowing at the material outlet of the guide pipe effectively disperses accumulated paper scraps near the outlet, allowing them to smoothly enter the compression chamber. This solves the problem of outlet blockage, ensuring continuous and stable operation of the device, improving the efficiency of recycled paper production, and reducing time and resource waste caused by downtime for handling blockages.

[0014] This invention connects the crushing component and the rotating rod via a pulley, enabling power linkage between the crushing component and the anti-clogging mechanism. The anti-clogging mechanism can be driven using the power source of the crushing component, eliminating the need for additional dedicated drive equipment. This effectively simplifies the overall structure of the device and reduces manufacturing and maintenance costs.

[0015] This invention, through the design of the guide plate, can guide the gas discharged from the exhaust hood during use, thereby enabling the airflow to act more effectively at the outlet of the guide pipe and improving the usage effect.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a recyclable device for recycled paper, including a processing box 1 and an anti-blocking mechanism 3. A crushing component 10 is provided on the top of the processing box 1, and a guide pipe 2 is provided on the processing box 1. There are two guide pipes 2.

[0024] The processing box 1 has a "V"-shaped paper inlet at the top and an inverted "V"-shaped paper conveying outlet at the bottom. The inlets of the two guide pipes 2 are connected to the paper conveying outlets to convey the shredded paper.

[0025] The feed tube 2 has an "L"-shaped inner cavity. The top of the feed tube 2 has a feed inlet that connects to the paper conveying port of the crushing component 10. The side wall of the feed tube 2 has a discharge port that connects to the inner cavity.

[0026] A collection box is provided at the bottom of the processing box 1, and the opening at the top of the collection box is located below the discharge port of the guide pipe 2.

[0027] The crushing assembly 10 includes two crushing rollers, each with a rotating shaft at both ends. One end of the rotating shaft extends out of the processing box 1 and is fixed to a first pulley, while the other end extends out and is connected to a drive unit, such as a servo motor.

[0028] The anti-blocking mechanism 3 includes a rotating rod 30 that rotates on the processing box 1. An eccentric wheel 32 is fixedly connected to the rotating rod 30. The rotating rod 30 is connected to the crushing assembly 10 via a belt 31.

[0029] Specifically, a second pulley is fixedly sleeved on the rotating rod 30, and a belt 31 is wound around the first pulley and the second pulley.

[0030] The rotating rod 30 is rotatably mounted on the side wall of the processing box 1 via a bearing seat. The bearing seat uses a self-lubricating bearing to reduce frictional resistance during rotation and reduce energy consumption. The eccentric wheel 32 is fixed on the rotating rod 30. The surface of the eccentric wheel is hardened to improve wear resistance and extend service life.

[0031] The anti-blocking mechanism 3 also includes a cylinder 33 fixed on the feed pipe 2. The top of the cylinder 33 has a cavity and the bottom has an air outlet. A retaining ring 34 is fixed inside the cavity. A piston rod 35 is movable inside the cavity. A sealing rubber ring is fitted on the outer wall of the piston rod 35. The end of the piston rod 35 located outside the cavity of the cylinder 33 is hemispherical. A spring 36 is fixed at the bottom of the piston rod 35. A ring 37 is fixed at the bottom of the spring 36. The ring 37 is clearance-fitted with the cavity and its outer diameter is larger than the inner diameter of the retaining ring 34. An air outlet pipe 38 connected to the air outlet is fixed at the bottom of the cylinder 33. One end of the air outlet pipe 38 passes through the feed pipe 2 and is fixed with an exhaust hood 39. The feed pipe 2 has a through hole that fits with the air outlet pipe 38.

[0032] The exhaust hood 39 has an exhaust port facing the discharge port of the guide pipe 2, and a filter screen is installed on the exhaust port.

[0033] Among them, the spring 36 is a highly elastic helical spring, which can enable the piston rod 35 to achieve stable reciprocating motion in the circular cavity under the action of the eccentric wheel 32. The ring 37 is fitted with the circular cavity with a clearance, which can not only ensure that the ring 37 can slide freely in the circular cavity, but also play a certain guiding role to prevent the piston rod 35 from deviating during the movement.

[0034] When recycled paper needs to be processed, the operator puts the paper in through the "V"-shaped paper inlet at the top of the processing box 1. The servo motor starts and drives the rotating shafts of the two crushing rollers in the crushing assembly 10 to rotate through the flexible coupling. The two crushing rollers rotate in opposite directions and use the serrated protrusions on their surfaces to squeeze and shear the paper, crushing it into fine fragments. The crushed paper fragments are guided by the inverted "V"-shaped paper conveying port at the bottom of the processing box 1 and enter the feed pipes 2 on both sides respectively.

[0035] While the crushing assembly 10 is working, the second pulley on the rotating rod 30 is connected to the first pulley via the belt 31, and is thus driven to rotate. The rotation of the rotating rod 30 causes the eccentric wheel 32 fixed on it to rotate as well. During the rotation, the eccentric wheel 32 continuously squeezes and releases the piston rod 35. When the eccentric wheel 32 squeezes the piston rod 35, the piston rod 35 moves downward against the elastic force of the spring 36. The air in the circular cavity is compressed and enters the air outlet pipe 38 through the air outlet, and is finally blown out from the exhaust hood 39. The blown gas forms an airflow inside the guide pipe 2, which blows away the paper scraps that may accumulate near the discharge port and prevents the guide pipe from being blocked. When the eccentric wheel 32 releases the piston rod 35, the piston rod 35 moves upward under the elastic force of the spring 36, and air is re-inhaled into the circular cavity to prepare for the next blowing.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
