Description

Technical Field

[0001] This utility model belongs to the field of high-draw masterbatch processing technology, specifically a pretreatment and grinding equipment for special powder raw materials of high-draw masterbatch. Background Technology

[0002] High-draw masterbatch powder is widely used in the plastics processing industry, especially in the production of plastic filaments, where it plays a crucial role. It typically requires good flowability, dispersibility, and a specific particle size distribution to ensure uniform extrusion and the formation of high-quality filaments during the drawing process. For example, high-draw masterbatch powder used in the production of woven plastic bags requires fine and uniform particle size to produce bags with high strength and a smooth surface.

[0003] Meanwhile, the patent specification with application number CN210187253U discloses a grinding device for preparing wire drawing powder, "including a machine body, a feed pipe fixedly connected to the top of the machine body, a first motor support plate fixedly connected to the back of the machine body, a first motor fixedly connected to the top of the first motor support plate, a crushing gear fixedly connected to the output shaft of the first motor through a coupling, a first connecting block fixedly connected to the front of the crushing gear, and a first connecting rod movably connected to the outer wall of the first connecting block. This grinding device for preparing wire drawing powder can achieve high grinding efficiency and high grinding fineness, thus solving the problem of low grinding efficiency and low grinding fineness of traditional wire drawing powder preparation devices. By crushing the wire drawing powder raw material twice and pressing it once, the device can process the wire drawing powder raw material more thoroughly, thereby further facilitating people's work, saving manpower and material resources, and having good use effect." Existing high-draw masterbatch raw material pretreatment and grinding equipment has the problem that the stirring and grinding functions are independent during use. This results in the raw materials needing to be transferred multiple times within the equipment, which not only wastes time but also easily causes raw material loss and reduces production efficiency. Secondly, the pretreatment of raw materials is not perfect, and there is a lack of an effective crushing and auxiliary agent addition system, which prevents the raw materials from reaching the ideal state before entering the grinding stage, increasing the difficulty of grinding and energy consumption.

[0004] Therefore, a pretreatment and grinding equipment for high-strength masterbatch raw materials is proposed to address the above problems. Utility Model Content

[0017] 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.

[0018] like Figures 1 to 5As shown, this utility model provides a pretreatment grinding equipment for high-strength masterbatch powder raw materials, including a grinding box 1, a cover plate 2 at the top of the grinding box 1, a grinding mechanism 3 on the cover plate 2 and the inner surface of the grinding box 1, and a crushing mechanism 5 installed on one side of the grinding box 1. The grinding mechanism 3 includes a power motor 31, which is fixedly connected to the cover plate 2. The output end of the power motor 31 passes through the cover plate 2 and is fixedly connected to a grinding rod 35. A connecting frame 32 is rotatably connected to the outer surface of the grinding rod 35. Three gears 33 are rotatably connected to the bottom end of the connecting frame 32. The three gears 33 mesh with a gear 42, which is fixedly sleeved with the grinding rod 35. Grinding rods 39 are fixedly connected to the top of each of the three gears 33. The outer surfaces of the grinding rods 35 and 39 are provided with several stirring points. The bottom ends of the mixing blade 37, grinding rod 35, and three grinding rods 39 are all fixedly connected to grinding heads 38. The inner surface of the grinding box 1 is fixedly connected to a grinding plate 40 that works with the grinding head 38. The top of the grinding plate 40 has several feeding holes 41. Through the unique transmission design of the gear 42 driving the three gears 33, the grinding rod 35 and the three grinding rods 39 work together. While the mixing blade 37 fully mixes the raw materials, the grinding head 38 and the grinding plate 40 work together to achieve efficient grinding, ensuring the uniformity of the raw materials and improving product quality.

[0019] Specifically, a feeding hopper 36 is fixedly connected to the bottom of the grinding box 1. The feeding hopper 36 is located directly below the grinding plate 40. The feeding hopper 36 can collect the ground raw materials falling through the feeding hole 41 of the grinding plate 40 in a timely manner, avoiding the accumulation of raw materials at the bottom of the grinding box 1, facilitating subsequent centralized collection and processing, and improving production efficiency.

[0020] like Figures 1 to 5 As shown, a toothed ring 34 is fixedly sleeved on the inner surface of the cover plate 2. Three gears 33 mesh with the toothed ring 34. The meshing of the toothed ring 34 with the gears 33 provides a stable track and support for the rotation of the gears 33, so that the three gears 33 can rotate stably while revolving around the gear 42, ensuring the stability and reliability of the grinding mechanism 3.

[0021] Furthermore, one end of the grinding box 1 is equipped with an auxiliary agent addition channel 4. The auxiliary agent addition channel 4 can add auxiliary agents, such as dispersants and lubricants, during the grinding process according to production needs, so that the auxiliary agents can be fully mixed with the raw materials, thereby improving the grinding performance of the raw materials and the quality of the final product.

[0022] like Figures 1 to 5As shown, several stirring blades 37 are all inclined, and the stirring blades 37 on the first grinding rod 35 have opposite inclination angles to the stirring blades 37 on the three second grinding rods 39. When the stirring blades 37 with opposite inclination angles rotate, they can form staggered stirring flow fields, generate stirring forces in different directions on the raw materials, further enhance the stirring effect, make the raw materials more uniformly mixed, and provide a better foundation for subsequent grinding.

[0023] It is worth noting that the crushing mechanism 5 includes a feeding slide 55 fixedly connected to the grinding box 1. The top of the feeding slide 55 is fixedly connected to a crushing box 51. Two crushing rollers 53 are rotatably connected to the inner surface of the crushing box 51. One end of each crushing roller 53 passes through the crushing box 51 and is fixedly connected to a crushing gear 54. The two crushing gears 54 mesh with each other. One end of the crushing box 51 is fixedly connected to a second power motor 56. The output end of the second power motor 56 is fixedly connected to one of the crushing gears 54. Through the relative rotation of the two crushing rollers 53, the raw material entering the crushing box 51 is crushed, and large particles are crushed into smaller particles suitable for grinding, reducing the grinding difficulty, improving the grinding efficiency, and reducing the grinding energy consumption.

[0024] like Figures 1 to 5 As shown, two guide plates 52 are fixedly connected to the top of the crushing box 51. Both guide plates 52 are inclined and mirror-distributed to prevent raw materials from accumulating in the corners of the crushing box 51, ensuring the continuity and uniformity of the crushing process and further improving the crushing effect.

[0025] Among them, the first power motor 31 and the second power motor 56 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motors in this utility model is common knowledge in the field, and their working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motors will not be explained in detail.

[0026] Working principle and process: During use, the raw material enters from the top of the crushing box 51. Driven by the second power motor 56, the two crushing gears 54 mesh with each other, driving the crushing roller 53 to rotate and crush the raw material. The crushed raw material slides into the grinding box 1 through the discharge chute 55. The first power motor 31 starts, driving the first grinding rod 35 to rotate. The second gear 42 on the first grinding rod 35 meshes with the three first gears 33, causing the first gears 33 to revolve around the second gear 42 and rotate on their own axis, thereby driving the second grinding rod 39 to rotate. The stirring blades 37 on the first grinding rod 35 and the second grinding rod 39 with opposite inclination angles fully stir and mix the raw material. At the same time, the grinding head 38 grinds the raw material on the grinding plate 40. The ground raw material falls into the discharge hopper 36 through the discharge hole 41 on the grinding plate 40. During the grinding process, auxiliary agents can be added through the auxiliary agent addition channel 4 to optimize the grinding effect of the raw material.
