Description

Technical Field

[0001] This utility model relates to the technical field of waste recycling equipment, specifically to a waste recycling mechanism for cardboard processing. Background Technology

[0002] Paperboard, also known as board paper, is a thick sheet of paper made from various pulps, composed of interwoven fibers. The difference between paperboard and paper is usually distinguished by basis weight and thickness. Generally, paper with a basis weight exceeding 250 g / m² and a thickness greater than 0.5 mm is called paperboard (alternatively, paper with a thickness greater than 0.1 mm is also called paperboard. Generally, a basis weight less than 250 g / m² is considered paper, while a basis weight of 250 g / m² or higher is considered paperboard).

[0003] Patent No. CN201922302829.8 discloses a waste recycling device for cardboard cutting, including a processing device and a cutting device, with the cutting device mounted on the top of the processing device. The processing device of this invention can effectively process the cut-off scraps, crushing them before collection, significantly reducing space waste and facilitating scrap collection and reuse. Through the cooperation of the first servo motor, fan blades, baffle, and collection port, scraps on the surface of the processing box are blown into the interior of the box, eliminating the need for manual collection and avoiding safety hazards. The cutting device, equipped with a limiting block and guide rail, effectively limits the cutting blade, preventing cutting displacement. Furthermore, this invention has a reasonable structure and is easy to use.

[0004] Traditional waste paper recycling systems simply use a collection bin to hold the waste paper, without the ability to centrally crush and separate the cardboard waste inside the bin for further processing. This results in low recycling efficiency and requires significant manpower and resources for secondary separation and crushing, making the process cumbersome and inefficient. Utility Model Content

[0005] In view of this, the present invention provides a waste recycling mechanism for cardboard processing, which can efficiently and quickly crush and process waste paper generated from cutting by means of a hopper and a crushing component, greatly improving its recycling efficiency. It solves the problem that traditional waste paper recycling components simply set up a simple collection bucket to hold the waste paper, and cannot centrally crush and separate the cardboard waste inside the collection bucket for further processing, resulting in low recycling efficiency and the need for a lot of manpower and resources for secondary separation and crushing, which is cumbersome and inefficient.

[0006] To solve the above-mentioned technical problems, this utility model provides a waste paper recycling mechanism for cardboard processing, including a waste paper collection assembly located at the tail of the waste paper conveyor belt of a paper cutter. The waste paper collection assembly includes a guide hopper located at the end of the conveyor belt in the conveying direction, a crushing assembly located at the outlet of the guide hopper, and a collection box located at the lower part of the crushing assembly. The crushing assembly includes a frame located at the end of the conveyor belt in the conveying direction, a drive component mounted on the frame, a crushing blade driven at the end of the output shaft of the drive component, a filter cylinder mounted on the frame, and the crushing blade rotatably mounted inside the filter cylinder. The opening of the collection box is located directly below the filter cylinder. This utility model can recycle waste paper from the conveyor belt. The guide hopper at the end of the transmission direction smoothly guides the debris generated during the crushing process, which is conveyed by the conveyor belt, into the crushing component. After being crushed by the crushing component, the debris is filtered by the filter cartridge and then collected and sorted. This solves the problem that traditional waste paper recycling components simply set up a simple collection bucket to hold the waste paper, without being able to centrally crush and separate the cardboard waste inside the collection bucket for further processing. This results in low waste paper recycling efficiency and requires a lot of manpower and resources for secondary separation and crushing, which is cumbersome and inefficient. This significantly improves the efficiency of waste paper recycling and reuse.

[0007] The feed hopper is a frustum-shaped cylindrical structure with an opening on the side closer to the paper cutter that is larger than the opening on the side farther from the paper cutter.

[0008] A protective box is installed on the frame. The upper part of the protective box is connected to the lower part of the guide hopper, which is inclined upward and set on the outside of the conveyor belt.

[0009] The filter cartridge is rotatably mounted on the frame and located inside the protective box. The upper part of the filter cartridge is an open structure, and multiple filter holes are opened on the side wall of the filter cartridge.

[0010] The outer side of the protective box is fitted with a sealed door via a hinge.

[0011] The driving component is a servo motor. The output shaft of the servo motor is equipped with a drive pulley. The outer side of the fixed shaft of the crushing blade is equipped with a driven pulley that is compatible with the drive pulley. The drive pulley and the driven pulley transmit power through a transmission belt. The diameter of the drive pulley is smaller than the diameter of the driven pulley.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. This utility model can drive the shredder blade connected to it to rotate by starting the output shaft of the servo motor, thereby achieving efficient shredding of waste paperboard generated during the cutting operation of the cutting machine falling through the guide hopper. The operation is simple and greatly improves the efficiency of waste paper recycling.

[0014] 2. This utility model can achieve a certain slope by designing the guide hopper as a frustum-shaped structure with one end opening larger than the other end opening, which facilitates the smooth sliding and collection of waste paper after cutting and conveying by the conveyor mechanism. Moreover, through this practical method, the end with the larger opening can completely wrap around the end of the conveyor belt, which facilitates the smooth sliding of materials for collection, making the operation safer and more convenient.

[0015] 3. This utility model can effectively isolate and protect the shredding components through the protective box, which facilitates the formation of a closed space and plays a certain role in blocking the paper scraps after cutting, making the operation safer and more convenient.

[0016] 4. This utility model allows the outer wall of one side of the protective box to be opened through a sealed door, making it easier for the operator to rotate the filter cylinder to a certain angle and remove and classify the remaining waste paper that has not been completely crushed, making the operation more convenient.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] like Figure 1-3As shown: This embodiment provides a waste recycling mechanism for cardboard processing, including a waste paper collection assembly 100 located at the tail of the waste paper conveyor belt of a paper cutter. The waste paper collection assembly 100 includes a guide hopper 110 located at the end of the conveyor belt in the conveying direction. A crushing assembly 120 is provided at the outlet of the guide hopper 110. A collection box 130 is provided at the lower part of the crushing assembly 120. The crushing assembly 120 includes a frame 121 located at the end of the conveyor belt in the conveying direction. A drive member 122 is provided on the frame 121. A crushing blade 123 is driven at the end of the output shaft of the drive member 122. A filter cylinder 140 is provided on the frame 121. The crushing blade 123 is rotatably disposed inside the filter cylinder 140. The opening of the collection box 130 is located in the filter cylinder 140. Directly below, this utility model uses a guide hopper 110 located at the end of the conveyor belt drive direction to smoothly guide the debris generated during the crushing process, which is conveyed by the conveyor belt, into the crushing component 120. After being crushed by the crushing component 120, the debris is filtered by the filter cylinder 140 and then collected and sorted. This solves the problem that traditional waste paper recycling components simply set up a simple collection bucket to hold the waste paper, and cannot centrally crush and separate the cardboard waste inside the collection bucket for further processing. This results in low waste paper recycling efficiency and requires a lot of manpower and resources for secondary separation and crushing, which is cumbersome and inefficient. This invention greatly improves the efficiency of waste paper recycling and reuse.

[0023] According to one embodiment of the present invention, such as Figure 1-3 As shown, the guide hopper 110 is a frustum-shaped cylindrical structure with an opening on the side closer to the paper cutter larger than the opening on the side farther from the paper cutter. This utility model can achieve a certain slope by designing the guide hopper 110 as a frustum-shaped structure with one end opening larger than the other end opening, which facilitates the smooth sliding and collection of waste paper conveyed by the conveyor mechanism after cutting. Moreover, through this practical method, the end with the larger opening can completely wrap around the end of the conveyor belt, which facilitates the smooth sliding of materials for collection, making the operation safer and more convenient.

[0024] According to another embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a protective box 200 is provided on the frame 121. The upper part of the protective box 200 is connected to the lower part of the guide hopper 110. The guide hopper 110 is inclined upward and set on the outside of the conveyor belt. This utility model can effectively isolate and protect the crushing component 120 through the protective box 200, which facilitates the formation of a closed space and plays a certain role in blocking the paper scraps after cutting, making the operation safer and more convenient.

[0025] According to another embodiment of the present invention, such as Figure 1 and Figure 3As shown, the filter cylinder 140 is rotatably mounted on the frame 121 and located inside the protective box 200. The filter cylinder 140 is fixed to the frame 121 by bearings and a rotating shaft, and the filter cylinder 140 has a through hole larger than the rotating shaft. The upper part of the filter cylinder 140 is an open structure, and multiple filter holes are provided on the side wall of the filter cylinder 140. This utility model can filter the paper scraps shredded by the shredder blade 123 through the filter holes on the filter cylinder 140. Moreover, the filter cylinder 140 can be used to temporarily block and isolate the waste paper to be shredded, making the operation safer and more convenient.

[0026] The protective box 200 is fitted with a sealing door 300 on the outside via a hinge. This utility model allows the outer side wall of the protective box 200 to be opened via the sealing door 300, making it easier for the operator to rotate the filter cylinder 140 to a certain angle and remove and classify the remaining waste paper that has not been completely crushed. This makes the operation more convenient.

[0027] The driving component 122 is a servo motor. The output shaft of the servo motor is equipped with a drive pulley. The outer side of the fixed shaft of the shredder 123 is equipped with a driven pulley adapted to the drive pulley. The drive pulley and the driven pulley transmit power through a transmission belt. The diameter of the drive pulley is smaller than that of the driven pulley. This utility model can rotate the output shaft of the servo motor to rotate the drive pulley together. The rotation of the drive pulley drives the transmission belt and the driven pulley together. The rotation of the driven pulley can drive the fixed shaft of the shredder 123 and the shredder 123 to rotate at the same time, realizing efficient shredding of waste paper falling into the shredding cylinder. The operation is more convenient and efficient.

[0028] How to use this utility model:

[0029] First, it needs to be clarified that the recycling mechanism involved in this utility model is mainly used for collecting various cutting wastes. This utility model takes the collection and treatment of waste generated during the cutting of cardboard as an example to describe its usage method in detail. It should be noted here that the paper cutter is a cutting device in the prior art, and the frame 121 of the paper cutter is equipped with an automatic conveyor belt, which is also a conveying device in the prior art. The belt is made of nylon. When it is necessary to recycle the cutting debris, the output shaft of the starter 122 is rotated. The rotation of the output shaft of the starter servo motor drives the drive pulley to rotate together. The rotation of the drive pulley drives the transmission belt and the driven pulley to rotate together. The rotation of the driven pulley can drive the fixed shaft of the shredder 123 and the shredder 123 to rotate, thereby realizing the efficient shredding of the waste paper falling into the shredding cylinder. The filter cylinder 140 filters the paper scraps shredded by the shredder 123 through the filter holes. It also temporarily blocks and isolates the waste paper to be shredded. After cutting, the operator opens the sealing door 300 and rotates the filter cylinder 140 to a certain angle to remove and classify the remaining incompletely shredded waste paper. This invention, using a hopper in conjunction with the shredder assembly 120, achieves efficient and rapid shredding and reprocessing of the waste paper generated during cutting, greatly improving recycling efficiency. It solves the problem of traditional waste paper recycling components that simply use a collection bucket to hold the paper scraps, failing to centrally shred and separate the cardboard waste inside the bucket for further processing. This results in low recycling efficiency and requires significant manpower and resources for secondary separation and shredding, leading to cumbersome and inefficient operations.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
