Description

Technical Field

[0001] This utility model relates to the field of paper scrap recycling technology, specifically a paper scrap recycling mechanism for use in a cardboard production workshop. Background Technology

[0002] Shredding waste paper is a crucial step in the recycling and reuse of waste paper. Shredded waste paper can be used to manufacture recycled paper, pulp, or other paper products, which has significant environmental and economic benefits. However, existing waste paper shredding equipment has many problems in practical applications and urgently needs improvement.

[0003] Patent number CN208468529U discloses a paper scrap recycling device, highlighting the limitations of existing devices. Low grinding efficiency Due to the fibrous structure and toughness of waste paper, its shredding efficiency is low, making it difficult to quickly shred waste paper into fine paper scraps. This is especially true when processing large quantities of waste paper, where insufficient equipment capacity leads to low production efficiency.

[0004] Uneven grinding effect In traditional shredding equipment, the fibrous structure of waste paper easily becomes entangled on the blades or hammers during the shredding process, resulting in uneven shredding. Some waste paper may not be fully shredded, while some paper scraps may be too fine, affecting the quality of subsequent processing. This uneven shredding effect not only reduces the recycling value of waste paper but also increases the difficulty of subsequent processing.

[0005] Lack of accessibility features Most existing shredding equipment lacks auxiliary functions, such as waste paper pretreatment or post-shredding cleaning. For example, waste paper typically requires pretreatment before entering the shredding unit to remove impurities and moisture. However, most equipment does not integrate these functions, increasing operational complexity and cost. Furthermore, shredded paper scraps easily clog the equipment's exhaust ports, affecting normal operation, but existing equipment lacks effective cleaning mechanisms.

[0006] Therefore, a paper scrap recycling system for cardboard production workshops is needed to improve the above-mentioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a paper scrap recycling mechanism for use in a cardboard production workshop, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: A paper scrap recycling mechanism for a cardboard production workshop includes a housing, and a shredding mechanism is provided on the upper side inside the housing. The shredding mechanism includes: Motor 2, which is fixedly mounted on the upper end of the housing, has a rotating shaft at its output end; A rotating plate is fixedly mounted on the surface of a rotating shaft, and a hammer is rotatably provided at one end of the rotating plate. A sieve cylinder, the lower end of which is rotatably mounted on the upper side of the transmission box via a meshing shaft; The meshing shaft is hollow inside, and the bottom of the screen cylinder is provided with several air jet holes, which are connected to the hollow interior of the meshing shaft.

[0009] As a preferred embodiment of this utility model, a plurality of fixed baffles are fixedly provided on the inner side of the sieve cylinder, and the fixed baffles and hammers are arranged alternately.

[0010] As a preferred embodiment of this utility model, an exhaust port is fixedly provided at the upper end of the outer shell, and a filter screen is provided inside the exhaust port.

[0011] As a preferred embodiment of this utility model, a brush is fixedly provided on the outside of the screen cylinder, and the brush is fitted and connected to the exhaust port.

[0012] As a preferred embodiment of this utility model, a transmission box is fixedly installed inside the transmission box, and one end of the meshing shaft is rotatably disposed inside the meshing shaft.

[0013] As a preferred embodiment of this utility model, a motor is fixedly installed inside the sealed box, and a gear is driven at the output end of the motor, which meshes with the meshing groove on the surface of the meshing shaft.

[0014] As a preferred embodiment of this utility model, an air pump is fixedly installed inside the transmission box, and the air pump is connected to the sealed box through a pipe.

[0015] As a preferred embodiment of this utility model, a collection groove is provided at the lower end of the inner shell.

[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, efficient pulverization and uniformity are achieved. Motor 1 drives gear 1 to rotate, which in turn drives the meshing shaft and screen cylinder to rotate, achieving uniform pretreatment and initial pulverization of waste paper. Simultaneously, motor 2 drives the rotating shaft and rotating plate to rotate, which, in conjunction with fixed baffles, causes the hammers to pound the waste paper, further improving pulverization efficiency and effectiveness. This dual pulverization mechanism not only improves pulverization efficiency but also ensures the uniformity of the pulverization effect, significantly enhancing the reuse value of waste paper.

[0017] 2. Auxiliary function integration An air pump is designed to blow air into the sealed chamber, which is then expelled through air jets, causing the waste paper to float disorderly for easier shredding. Simultaneously, a brush cleans the exhaust port to prevent blockage and ensure normal operation of the equipment. This integrated auxiliary function design not only improves shredding efficiency but also reduces equipment wear and maintenance costs, extending the equipment's lifespan.

[0018] 3. Reduce environmental pollution Cleaning the exhaust vents with a brush prevents blockages, ensures the normal operation of the equipment, reduces dust leakage caused by blockages, lowers environmental pollution, and meets environmental protection requirements. Attached Figure Description

[0021] 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.

[0022] In the description of this application, it should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0023] like Figures 1 to 5 As shown, the existing technology in this embodiment has the following problems: The inventors found that the existing technology discloses a paper scrap recycling device, which has the following limitations: low crushing efficiency. Due to the fibrous structure and toughness of waste paper, the crushing efficiency is low, and it is difficult to quickly crush waste paper into fine paper scraps. Especially when processing large amounts of waste paper, the processing capacity of the equipment is insufficient, resulting in low production efficiency; uneven crushing effect. In the traditional crushing device, the fibrous structure of waste paper is easily wrapped around the blades or hammers during the crushing process, resulting in uneven crushing effect. Some waste paper may not be fully crushed, while some paper scraps may be too fine, affecting the quality of subsequent processing. This uneven crushing effect not only reduces the reuse value of waste paper, but also increases the difficulty of subsequent processing; lack of auxiliary functions. Most existing crushing devices lack auxiliary functions, such as waste paper pretreatment or post-crushing cleaning. For example, waste paper usually needs to be pretreated before entering the crushing device to remove impurities and moisture. However, most devices do not integrate these functions, increasing the complexity and cost of operation. In addition, the crushed paper scraps are easy to clog the equipment's exhaust port, affecting the normal operation of the equipment, but existing devices lack an effective cleaning mechanism; Therefore, the inventor provides a paper scrap recycling mechanism for a cardboard production workshop, including a housing 1, and a crushing mechanism 9 is provided on the upper side inside the housing 1. The crushing mechanism 9 includes: Motor 2 10 is fixedly mounted on the upper end of housing 1, and a rotating shaft 11 is provided at the output end of motor 2 10. Motor 2 10 serves as the power source for the shredding mechanism 9, and transmits power to the rotating plate 12 through the rotating shaft 11, thereby realizing the shredding operation of waste paper.

[0024] A rotating plate 12 is fixedly mounted on the surface of a rotating shaft 11, and a hammer 13 is rotatably mounted at one end of the rotating plate 12. The hammer 13 rotates at high speed under the drive of the rotating plate 12, and beats the waste paper in the screen cylinder 14, breaking it into smaller paper scraps.

[0025] The screen cylinder 14 is rotatably mounted on the upper side of the transmission box 4 via a meshing shaft 8 at its lower end. The screen cylinder 14 is the main part for waste paper shredding, and its internal structure is rationally designed to effectively improve shredding efficiency.

[0026] The meshing shaft 8 is hollow inside, and the bottom of the screen cylinder 14 has several air jet holes 17, which are connected to the hollow interior of the meshing shaft 8. Air is blown into the sealed box 7 by the air pump 6. The gas passes through the hollow part of the meshing shaft 8 and is ejected from the air jet holes 17 at the bottom of the screen cylinder 14, causing the waste paper to float disorderly within the screen cylinder 14, facilitating shredding. The properly shredded paper scraps pass through the screen cylinder 14 and fall into the collection trough 5, while a brush 15 cleans the exhaust port 18 to prevent blockage.

[0027] As an example of this utility model, a plurality of fixed baffles 16 are fixedly provided on the inner side of the screen cylinder 14, and the fixed baffles 16 and the hammer blades 13 are arranged alternately. This alternate arrangement can increase the contact opportunity between waste paper and hammer blades 13 and improve the crushing efficiency.

[0028] As an example of this utility model, an exhaust port 18 is fixedly provided at the upper end of the outer shell 1, through which internal air is discharged. A filter screen is provided inside the exhaust port 18 to filter out internal debris and prevent it from being sprayed out and affecting the air. The filter screen design not only prevents debris such as paper scraps from being discharged, but also effectively reduces dust leakage and protects the workshop environment.

[0029] As an example of this utility model, a brush 15 is fixedly provided on the outside of the sieve cylinder 14, and the brush 15 is in close contact with the exhaust port 18. During the rotation of the sieve cylinder 14, the brush 15 can continuously clean the exhaust port 18, prevent paper scraps from clogging the exhaust port 18, and ensure smooth exhaust.

[0030] As an example of this utility model, a transmission housing 4 is fixedly installed inside the transmission housing 4, and one end of the meshing shaft 8 is rotatably disposed inside the transmission housing 4. The transmission housing 4 provides stable support and a transmission environment for the meshing shaft 8, ensuring its normal operation.

[0031] As an example of this utility model, a motor 3 is fixedly installed inside the sealed box 7. A gear 2 is driven at the output end of the motor 3, and the gear 2 meshes with a meshing groove on the surface of the meshing shaft 8. The motor 3 drives the meshing shaft 8 to rotate through the gear 2, thereby driving the screen cylinder 14 to rotate, realizing the initial separation and crushing of waste paper.

[0032] As an example of this utility model, an air pump 6 is fixedly installed inside the transmission box 4, and the air pump 6 is connected to the sealed box 7 through a pipe. The air pump 6 provides an air source for the air jet holes 17 inside the screen cylinder 14. The gas ejected through the air jet holes 17 causes the waste paper to float disorderly inside the screen cylinder 14, further improving the crushing efficiency.

[0033] As an example of this utility model, a collection trough 5 is provided at the lower end of the inner surface of the outer casing 1. The collection trough 5 is used to collect qualified shredded paper scraps, ensuring the efficient recycling and utilization of paper scraps.

[0034] Working principle: When in use, waste paper is put into the screen cylinder 14. Motor 1 3 drives gear 1 2 to rotate, which in turn drives the meshing shaft 8 to rotate, which in turn drives the screen cylinder 14 to rotate. Motor 2 10 starts and drives the rotating shaft 11 to rotate, which in turn drives the rotating plate 12 to rotate. With the help of the fixed baffle 16, the hammer 13 beats the waste paper. Air pump 6 blows air into the sealed box 7 and sprays it out through the air jet hole 17, which makes the waste paper float disorderly, making it easy to crush. The crushed paper scraps pass through the screen cylinder 14 and fall into the collection tank 5. At the same time, the brush 15 cleans the exhaust port 18 to prevent blockage.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
