Description

Technical Field

[0001] The present invention relates to the field of 5G communication technology, and particularly to a raw material crushing device for paper product processing. Background Art

[0002] In the paper product processing industry, the crushing of raw materials is a crucial link. The raw materials of paper, such as wood, waste paper, etc., must be crushed so as to be converted into cellulose fibers suitable for papermaking. The traditional raw material crushing technologies mainly focus on cutting and grinding.

[0003] The cutting-type crushing technology mainly relies on physical shearing action. Tools such as blades and cutter wheels are used to cut the raw materials into small pieces or fibrous shapes. Although this method is fast in processing raw materials, the shearing process is likely to damage the fibers, destroying the length and strength of the fibers and affecting the quality of the subsequent paper.

[0004] The grinding-type crushing technology uses tools such as grinding discs and grinding wheels to break the raw materials through the frictional force generated by high-speed rotation. This method can make the raw materials more delicate, but there are also certain problems. For example, it may cause excessive fragmentation of the fibers, loss of the natural structure of the fibers, and at the same time increase energy consumption and production costs.

[0005] Although these two traditional crushing methods have been widely used in the paper product processing industry, the damage to the fibers during the raw material processing process, especially the influence on their length and strength, has become a bottleneck for improving the paper quality. Maintaining the integrity of the raw material fibers is crucial for improving the physical properties of the paper such as tear strength, tensile strength, and flexibility. Therefore, finding a new crushing process that can minimize the damage to the fibers has become a key requirement for the industry development.

[0006] Therefore, there is an urgent need for a raw material crushing device for paper product processing that can both crush the raw materials and retain the integrity of the raw material fibers as much as possible to solve the above problems. Summary of the Invention

[0007] The purpose of the present invention is to provide a raw material crushing device for paper product processing to solve the problems raised in the above background art.

[0008] To solve the above technical problems, the present invention provides the following technical solutions: including,

[0009] N rubbing components, arranged in a circumferential array and forming a cylindrical bin capable of storing raw materials, and each rubbing component is composed of a first rubbing plate and a second rubbing plate that can move in opposite directions;

[0010] Extrusion rollers, arranged in the cylindrical bin and capable of rotating relative to each other in the cylindrical bin to complete the action of tearing the raw materials;

[0011] An alternating transmission mechanism, with the transmission end connected to the extrusion roller, and the action ends are respectively arranged on the top surfaces of the first kneading plate and the second kneading plate, so as to complete the reverse movement action by the rotation and extrusion of the transmission end on the action ends.

[0012] Preferably, a plurality of raised balls are arranged on both the first kneading plate and the second kneading plate. A plurality of friction rods with arc-shaped ends are linearly arrayed on one side of the raised balls. Stirring blocks are symmetrically arranged on the friction rods, and there is an included angle between the stirring block and the friction block, where 90° < included angle < 180°. The stirring block is integrally arc-shaped without sharp parts.

[0013] Preferably, the transmission end of the alternating transmission mechanism includes

[0014] A connecting ring arranged on the extrusion roller;

[0015] Extension rods, which are alternately arranged in a circumferential array at the intersection of the outer peripheral side of the connecting ring with the top surface and the bottom surface;

[0016] Arc-shaped extrusion blocks, symmetrically arranged at the ends of the extension rods away from the connecting ring;

[0017] The action end of the alternating transmission mechanism includes

[0018] A single-slot bin arranged on the first kneading plate;

[0019] A double-slot bin arranged on the second kneading plate;

[0020] Contact blocks, respectively arranged on the single-slot bin and the double-slot bin.

[0021] Preferably, a housing is arranged on the outer peripheral side of the cylindrical bin. A conical guiding block is arranged on the top surface of the extrusion roller. A conical feed inlet is arranged at the feed end of the housing, and its minimum inner diameter is greater than the minimum inner diameter of the guiding block.

[0022] Preferably, a motor is arranged on the top surface of the housing through a bracket, and its power output end is connected to the extrusion roller.

[0023] Preferably, telescopic bins are arranged on the bottom surfaces of both the first kneading plate and the second kneading plate. A stirring bin is arranged on the bottom surface of the telescopic bin. Stirring arms are arranged on the bottom surface of the extrusion roller.

[0024] Preferably, a plurality of friction columns are arranged in a circumferential array on the outer peripheral side of the extrusion roller.

[0025] Preferably, a vibration motor is arranged on the outer peripheral side of the housing.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] Multi-directional kneading and tearing function: Due to the circumferential array setting of N kneading components and the relative rotation design of the extrusion rollers, the raw materials are kneaded and torn by forces in multiple directions inside the cylindrical bin, thus achieving a more comprehensive and efficient processing of the raw materials.

[0028] 1. Continuous reverse movement mechanism: The continuous up-and-down reverse movement of the first kneading plate and the second kneading plate is controlled by the alternating drive mechanism, ensuring that the forces exerted on the raw materials during the processing are dynamically changing, improving the processing efficiency and the processing quality of the raw materials.

[0029] 2. Fine processing structure: The design of the raised balls, arc friction rods and picking blocks provided on the first kneading plate and the second kneading plate enables a more detailed processing of the raw materials during the kneading and tearing process, reducing the risk of excessive damage to the raw materials.

[0030] 3. Smooth raw material feeding and discharging: The frustum-shaped design of the guiding block and the feeding port, as well as the connection between the extrusion rollers and the motor, ensure that the raw materials can be smoothly fed into the processing area and effectively transferred to the mixing bin after processing, improving the continuous operation ability of the entire system.

[0031] 4. Improvement in automation and mechanization: Through the use of the motor, the entire raw material processing process is automated. At the same time, the setting of the vibration motor makes it easier for the crushed raw materials to be transferred to the subsequent processing stage, reducing manual intervention and improving production efficiency and safety.

[0032] Increased mixing function: The mixing arms on the bottom surface of the extrusion rollers are combined with the mixing bin, enabling the raw materials to be further stirred and mixed after being kneaded and torn, providing a more uniform material basis for the production of semi-finished products.

[0033] Through the above design features, the entire device can effectively process the raw materials with high efficiency and quality, meet the requirements of modern large-scale production, and has high industrial application value. Brief Description of the Drawings

[0044] To make the purpose, technical solution, and advantages of the present invention clearer, the following will further describe the embodiments of the present invention in detail in conjunction with the accompanying drawings.

[0045] Embodiment 1

[0046] Figures 1 - 7 Shown is a schematic diagram of the structure of the first embodiment of a raw material crushing device for paper product processing according to the present invention. Please refer to Figures 1 - 7 , a raw material crushing device for paper product processing in this embodiment includes,

[0047] N kneading components are arranged in a circumferential array and form a cylindrical bin capable of storing raw materials, and each kneading component is composed of a first kneading plate 100 and a second kneading plate 200 that can move in opposite directions. The raw materials are placed in the cylindrical bin, and the raw materials are kneaded and torn in two directions by the first kneading plate 100 and the second kneading plate 200 that can move in opposite directions to complete the crushing action;

[0048] The extrusion roller 300 is arranged in the cylindrical bin and can rotate relative to the cylindrical bin to complete the action of tearing the raw materials, applying a force in a third direction to the raw materials by means of the extrusion roller 300, further enhancing the pulverizing effect;

[0049] The transmission end of the alternating transmission mechanism is connected to the extrusion roller 300, and the action ends are respectively arranged on the top surfaces of the first kneading plate 100 and the second kneading plate 200. By the rotation and extrusion of the transmission end, the action ends complete the reverse movement action. By the rotation of the extrusion roller 300, the action ends of the alternating transmission mechanism are driven to rotate, thereby driving the action ends to move in the reverse direction, and finally driving the first kneading plate 100 and the second kneading plate 200 to move in the reverse direction.

[0050] Specifically, a plurality of protruding balls 500 are arranged on both the first kneading plate 100 and the second kneading plate 200. A plurality of friction rods 600 with arc-shaped ends are linearly arrayed on one side of the protruding balls 500. Stirring blocks 700 are symmetrically arranged on the friction rods 600, and there is an included angle between the stirring blocks 700 and the friction blocks, 90° < included angle < 180°. The stirring blocks 700 are integrally arc-shaped and have no sharp parts. Since a plurality of protruding balls 500 are arranged on both the first kneading plate 100 and the second kneading plate 200, the contact area with the raw materials is increased. When the friction rods 600 with arc-shaped ends contact the raw materials, a large frictional force is generated, thus assisting the kneading force generated on the raw materials during their up-and-down movement. Stirring blocks 700 are symmetrically arranged at both the upper and lower ends thereof, and the included angle range between them and the friction rods 600 is 90° < included angle < 180°. When the friction rods 600 move upward, the stirring blocks 700 located on their top surfaces will play an upward picking role for the raw materials. Similarly, when moving downward, they will play a downward picking role, which can not only increase the kneading force but also adjust the state of the raw materials in preparation for better kneading next time. Moreover, the stirring blocks 700 are integrally arc-shaped and have no sharp parts, so they can only generate kneading force, and since they have no sharp parts, that is, there is no possibility of forming a relatively narrow space, thereby reducing the possibility of the raw materials being hidden in a narrow space.

[0051] Specifically, the transmission end of the alternating transmission mechanism includes,

[0052] A connecting ring 401 is arranged on the extrusion roller 300. Extension rods 402 are alternately arranged in a circumferential array at the intersection positions of the outer peripheral side, the top surface, and the bottom surface of the connecting ring 401. Arc-shaped extrusion blocks 403 are symmetrically arranged at the ends of the extension rods 402 far from the connecting ring 401. By the rotation of the extrusion roller 300, the connecting ring 401 is driven to rotate, thereby driving the extension rods 402 to rotate. Since there is a certain distance between adjacent extension rods 402 when designing the extension rods 402, different regions can be extruded by means of the arc-shaped extrusion blocks 403.

[0053] The action end of the alternating transmission mechanism includes,

[0054] The single-slot bin 404 is arranged on the first kneading plate 100, the double-slot bin 405 is arranged on the second kneading plate 200, and the contact blocks 406 are respectively arranged on the single-slot bin 404 and the double-slot bin 405. When the top surface of the arc-shaped pressing block 403 on the top surface of the connecting ring 401 contacts and presses the contact block 406 on the top surface of the single-slot bin 404 bin body, it will drive the single-slot bin 404 and the first kneading plate 100 on its surface to move upward. And when its bottom surface contacts the contact block 406 on the bottom surface of the upper slot of the double-slot bin 405, it will drive the second kneading plate 200 on the double-slot bin 405 to move downward. In this way, the first kneading plate 100 and the second kneading plate 200 can be driven to move in opposite directions. Similarly, when the bottom surface of the arc-shaped pressing block 403 on the bottom surface of the connecting ring 401 contacts and presses the contact block 406 on the bottom surface of the single-slot bin 404 bin body, it will drive the single-slot bin 404 and the first kneading plate 100 on its surface to move downward. And when its bottom surface contacts the contact block 406 on the top of the lower slot of the double-slot bin 405, it will drive the second kneading plate 200 on the double-slot bin 405 to move upward. Through continuous extrusion, the continuous reciprocating movement of the first kneading plate 100 and the second kneading plate 200 is realized.

[0055] Specifically, a housing 800 is arranged on the outer peripheral side of the cylindrical bin. A conical guiding block 900 is arranged on the top surface of the extrusion roller 300. A conical feeding port 1000 is arranged at the feeding end of the housing 800, and its minimum inner diameter is larger than the minimum inner diameter of the guiding block 900. When raw materials are poured into the feeding port 1000, due to its conical design, it can move towards the cylindrical bin under the guidance of the inclined surface. And the guiding block 900 is also conical and can also guide the raw materials. The guiding block 900 can rotate, and the occurrence of raw material blockage problems can be greatly prevented under the action of rotation.

[0056] Specifically, a motor 1100 is arranged on the top surface of the housing 800 through a bracket, and its power output end is connected to the extrusion roller 300, and the motor 1100 is used to provide power for the extrusion roller 300 and the guiding block 900 on its surface.

[0057] Specifically, telescopic bins 1200 are arranged on the bottom surfaces of the first kneading plate 100 and the second kneading plate 200. A stirring bin 1300 is arranged on the bottom surface of the telescopic bin 1200. A stirring arm 1400 is arranged on the bottom surface of the extrusion roller 300. With the telescopic bin 1200, the sealing performance of the cylindrical bin will not be damaged when the first kneading plate 100 and the second kneading plate 200 move, preventing raw materials from overflowing. And the raw materials are stirred by the stirring bin 1300 and the rotating stirring arm 1400 to make pulp water, reducing the subsequent papermaking process.

[0058] Specifically, a plurality of friction columns 1500 are arranged in a circumferential array on the outer peripheral side of the extrusion roller 300, and the friction columns 1500 are used to increase the frictional force between the extrusion roller 300 and the raw material.

[0059] Specifically, a vibration motor 1600 is arranged on the outer peripheral side of the housing 800, and the vibration motor 1600 is used to make it easier for the raw material to fall into the mixing bin 1300.

[0060] During use:

[0061] Before processing the raw material, the operator needs to ensure that the mixing bin 1300 of the processing device is filled with an appropriate amount of pulp water to prepare for receiving and mixing the processed raw material. Immediately afterwards, the raw material to be processed is poured into the feed port 1000 of the equipment, which is the first step to start the processing process. Next, the operator activates the motor 1100, which drives the extrusion roller 300 to create the required extrusion force and rotational movement for the raw material. At the same time, the auxiliary vibration motor 1600 is started to ensure that the raw material can move smoothly during the processing.

[0062] When the raw material enters the cylindrical bin, it will encounter a series of carefully designed kneading plates. The structural features such as the convex balls 500, arc friction rods 600, and stirring blocks 700 on these kneading plates are used for fine processing of the raw material. These kneading plates move precisely up and down in the opposite direction under the control of the alternating drive mechanism, working in coordination with the rotation of the extrusion roller 300 to achieve comprehensive kneading and tearing of the raw material, which not only enhances the processing effect but also avoids excessive damage to the raw material.

[0063] The processed raw material is introduced into the mixing bin 1300 with the assistance of the vibration motor 1100. At this stage, the raw material is mixed with the pulp water, and the stirring arms 1400 at the bottom of the extrusion roller 300 further ensure the uniformity of the mixture. This mixing process is crucial for the quality of the final semi-finished product because it ensures the uniform distribution of the raw material and the consistency of the final product.

[0064] After the entire processing process is completed, the operator needs to turn off all the motors 1100 and clean the device to ensure that there is no residual raw material hindering the next batch of processing.

[0065] Although the present invention has been described above with reference to embodiments, various modifications can be made thereto and components thereof can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed by the present invention can be combined with each other in any way, and the exhaustive description of these combinations is not given in this specification only for the consideration of saving space and resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
