Technical Field

[0001] This utility model relates to the technical field of starch adhesive production equipment, specifically a combined crushing and screening machine for the pretreatment of raw materials for starch adhesive production. Background Technology

[0002] In the production of starch adhesives, the pretreatment of raw materials is a crucial step. Currently, the crushing and screening of raw materials for starch adhesive production are mostly carried out in separate steps using independent equipment.

[0003] This traditional method has many drawbacks: Firstly, the equipment occupies a large area, requiring significant production space and increasing the company's site costs. Secondly, the step-by-step operation process is cumbersome; transferring the crushed raw materials to the screening equipment not only consumes a lot of manpower and time but also easily causes material loss and contamination during the transfer process, affecting product quality and production efficiency. Furthermore, existing crushing equipment produces uneven crushing results, and screening equipment has limited screening accuracy, making it difficult to meet the requirements of high-quality starch glue production for raw material pretreatment.

[0004] Therefore, it is necessary to design a combined crushing and screening machine for the pretreatment of starch glue production raw materials to solve the problems mentioned above. Utility Model Content

[0029] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0030] A combined crushing and screening machine for pretreatment of raw materials in starch glue production includes:

[0031] Feed hopper 1 is designed in the shape of a funnel and has an anti-stick coating on the inner wall to reduce the adhesion of raw materials to the inner wall of the funnel and ensure smooth feeding. The starch glue production raw materials are placed above the feed hopper 1. The raw materials slide down the inner wall of the funnel by their own gravity. The anti-stick coating reduces the adhesion of the raw materials to the inner wall and ensures that the raw materials enter the crushing unit 2 below smoothly.

[0032] The crushing unit 2, fixedly connected to the bottom of the feed hopper 1, includes a crushing shell 21. Multiple sets of crushing teeth 22 are installed inside the crushing shell 21, and one side of each crushing tooth 22 is connected to a drive motor 23 via a coupling 25. The multiple crushing teeth 22 are simultaneously connected by a transmission gear set 24. When the drive motor 23 is started, it drives the connected crushing tooth 22 to rotate via the coupling 25. This crushing tooth 22 then drives the other crushing teeth 22 to operate synchronously via the transmission gear set 24. Raw materials falling from the feed hopper 1 enter the crushing shell 21 and are crushed by the interaction of the multiple sets of crushing teeth 22. The coordinated work of the multiple sets of crushing teeth 22 ensures uniform force on the raw materials, achieving efficient and thorough crushing and producing materials with relatively uniform particle size. The wear-resistant layer on the inner wall of the crushing shell 21 resists frictional wear during raw material crushing, extending the service life of the crushing shell 21. The protective cover on the outside of the transmission gear set 24 prevents dust intrusion, ensuring transmission stability and the lifespan of the gear set.

[0033] The screening unit 3 includes a screening housing 31 fixedly connected to the bottom of the crushing unit 2. The bottom of the screening housing 31 has first screening holes 32 and second screening holes 33 with different apertures. The crushed material falls into the screening housing 31. The vibration motor 5 is activated, driving the vibration spring 6 to vibrate, causing the screening housing 31 and the material inside to vibrate. Under the vibration, the material passes through the first screening holes 32 and the second screening holes 33 according to particle size. Simultaneously, the conveying motor 71 drives the conveying screw 72 to rotate via a coupling, conveying the screened material to a designated position. The vibration device facilitates rapid material passage through the screen holes, preventing blockage and significantly improving screening efficiency. The different apertures of the first screening holes 32 and the second screening holes 33 enable precise material grading. The detachable screen design allows for easy screen replacement and adjustment of screening accuracy according to production needs. The conveying structure 7 enables automatic material conveying, reducing manual intervention and improving production continuity.

[0034] The receiving unit 4 includes a receiving box 41, whose bottom is moved by rollers. Materials screened by the screening unit 3 and conveyed by the conveying structure 7 fall into different receiving spaces within the receiving box 41 (divided by partitions). After receiving, the receiving box 41 can be moved by the bottom rollers to transport the materials to subsequent production stages. The partitions allow for the classified collection of materials of different particle sizes, facilitating on-demand retrieval in subsequent production processes. The roller design facilitates the movement of the receiving box 41, improving the flexibility of material transfer and reducing the intensity and time cost of manual handling.

[0035] Specifically, the inner wall of the crushing shell 21 is provided with a wear-resistant layer to improve the service life of the crushing shell 21 and reduce wear caused by long-term crushing operation.

[0036] Specifically, the outer side of the transmission gear set 24 adopts a protective structure, which is a protective cover, to prevent dust generated during the crushing process from entering the gear set and affecting the transmission effect and service life.

[0037] Specifically, a soundproof cover is provided on the outside of the drive motor 23 to reduce the noise generated by the drive motor 23 during operation and improve the working environment.

[0038] Specifically, a vibration device is installed inside the screening housing 31. The vibration device includes a vibration motor 5 and a vibration spring 6. Vibration makes the raw material pass through the first screening hole 32 and the second screening hole 33 more smoothly, thereby improving the screening efficiency.

[0039] Specifically, both the first screening hole 32 and the second screening hole 33 are designed to be detachable, making it convenient to replace the screen with a different aperture according to different screening requirements.

[0040] Specifically, the screening unit 3 is also equipped with a conveying structure 7, which includes a conveying motor 71 and a conveying screw 72. The conveying motor 71 and the conveying screw 72 are connected by a coupling.

[0041] Specifically, the receiving box 41 is equipped with a partition plate inside, which divides the receiving box 41 into multiple independent receiving spaces, which respectively receive the raw materials passing through the first screening hole 32 and the second screening hole 33.

[0042] The working process of this utility model is as follows: When using this combined crushing and screening integrated machine for pre-treatment of starch glue production raw materials, the raw material first enters the equipment through the feeding funnel 1. The anti-stick coating ensures smooth feeding. Then, the drive motor 23 drives the crushing teeth 22 to rotate. Through the transmission gear set 24, multiple sets of crushing teeth operate synchronously to fully crush the raw material. The wear-resistant layer and protective cover protect the crushing shell 21 and the transmission gear set 24, respectively. The crushed material falls into the screening shell 31. The vibration motor 5 and vibration spring 6 generate vibration, accelerating the material to pass through the first screening hole 32 and the second screening hole 33 to complete the classification. The detachable screen facilitates the adjustment of screening accuracy. The conveying motor 71 drives the conveying screw 72 to transport the screened material to the receiving unit 4. The material enters different receiving spaces of the receiving box 41 according to the particle size, and is conveniently transferred by the bottom rollers.

[0043] 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.
