Description

Technical Field

[0001] This utility model relates to the field of molding compound production and processing technology, and in particular to a ball milling device for processing antibacterial amino molding compounds. Background Technology

[0002] Ball milling equipment is a device used to process antibacterial amino molding compounds. Its main function is to ball mill the amino molding compounds and improve the dispersion uniformity of antibacterial agents. The material enters the cylinder through the feed inlet. Driven by a variable frequency motor, the grinding balls are subjected to centrifugal force and move in a parabolic motion, crushing the material through impact and shearing force.

[0003] Existing ball mill equipment such as Figure 1 As shown, it mainly includes a drive assembly and a rotating drum for placing materials. The two ends of the rotating drum are respectively provided with a feed port and a discharge port, and the inside of the rotating drum is provided with grinding balls for crushing the materials.

[0004] Existing technology involves placing materials inside a rotating drum for ball milling. After a certain time, the milled material is discharged through a discharge port and then screened. Qualified material is discharged, while unqualified material is conveyed back to the rotating drum for further ball milling. Since ball milling and screening are performed separately, the processing efficiency is low, and it is difficult to discharge qualified material in a timely manner. Qualified material remaining inside the mill drum can be over-crushed due to continuous impact from the grinding balls, causing secondary particle aggregation (agglomeration effect). This reduces the uniformity of antibacterial agent dispersion and makes the screen prone to clogging, leading to a decrease in the pass rate of qualified material.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this utility model, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] To address the problems of low processing efficiency and easy clogging of screens caused by the inability to discharge qualified materials in a timely manner in existing technologies, this utility model provides a ball milling device for processing antibacterial amino molding compounds.

[0007] The ball milling equipment for processing antibacterial amino molding compounds provided by this utility model adopts the following technical solution:

[0008] A ball milling device for processing antibacterial amino molding compound includes a drive assembly and a rotating drum connected to the drive assembly. The rotating drum is equipped with grinding balls of different sizes, and a sieve assembly that can be elastically adjusted is fixedly installed inside the rotating drum.

[0009] When the rotating drum is driven by the drive component, it drives the internal grinding balls and materials to rotate and grind the materials. Then, the qualified materials can be collected and discharged through the screening component. At the same time, as the drum rotates, the internal materials will hit the surface of the screening component to generate vibration and prevent material blockage.

[0010] Furthermore, the rotating drum is divided into a ball mill section for processing materials and a collection section for collecting and discharging materials by a screening assembly.

[0011] Furthermore, the screening assembly includes fixed members symmetrically arranged inside the rotating drum, with springs inside the fixed members, a screening component in the middle of the symmetrically arranged fixed members, and adjusting components fixedly connected to both sides of the screening component.

[0012] Furthermore, the fixing component has an installation groove inside, one end of the spring is fixedly installed inside the installation groove, and the other end is fixedly connected to the end of the adjusting component away from the screening component. The fixing component is slidably connected to the installation groove.

[0013] Furthermore, the bottom end of the drive assembly is fixedly connected to a base plate, and the two ends of the rotating drum are rotatably connected to bearing seats. The bottom end of the bearing seats is fixedly installed on the upper end of the base plate. The two ends of the rotating drum are respectively provided with a feed port and a discharge port, and the feed port and discharge port pass through the bearing seats and are fixedly connected to the rotating drum.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] The present invention discloses a ball milling device for processing antibacterial amino molding compounds. The device drives the rotating drum to rotate via a drive component, which in turn drives the internal grinding balls and materials to rotate. The grinding balls then perform ball milling on the materials. The qualified materials are then screened by a screening component and collected and discharged by a collection section. By screening and collecting the qualified materials during the ball milling process, over-milling is avoided, thereby improving the dispersion uniformity of the internal antibacterial agent. At the same time, as the rotating drum rotates, the internal materials collide with the surface of the screening component, causing vibration and preventing material blockage.

[0024] The following is in conjunction with the appendix Figure 1-7 The present invention will be described in further detail below.

[0025] Example 1: A ball milling device for processing antibacterial amino molding compound includes a drive assembly 2 and a rotating drum 4 connected to the drive assembly 2. The rotating drum 4 is equipped with grinding balls 8 of different sizes inside, and a sieve assembly 5 that can be elastically adjusted is fixedly installed inside the rotating drum 4. When the rotating drum 4 is driven by the drive assembly 2, it drives the grinding balls 8 and the material inside to rotate and grind the material through the grinding balls 8. Then, the qualified material can be collected and discharged through the sieve assembly 5. At the same time, as the rotating drum 4 rotates, the material inside will hit the surface of the sieve assembly 5 to generate vibration and avoid material blockage.

[0026] Specifically, when the material impacts the elastically adjustable screening component 5, the screening component 5 will elastically adjust and vibrate. This vibration will break the adhesion and friction between the material and the screening component 52, causing the material that was originally blocked in the filter holes to loosen and fall off, thereby restoring the screening function of the screening component 5. By screening and collecting qualified materials in the ball milling process, over-ball milling is avoided, thereby improving the dispersion uniformity of the internal antibacterial agent. The rotating drum 4 drives the grinding balls 8 to a certain drop height, so that they drop and grind the material. The mutual friction and compression between the grinding balls 8 also have a grinding effect on the material.

[0027] In this embodiment, as Figure 3 As shown, the rotating drum 4 is divided into a ball milling section 41 for processing materials and a collection section 42 for collecting and discharging materials by the screening component 5. As the rotating drum 4 rotates, qualified materials enter the collection section 42 through the screening component 5 for collection and can be discharged through the discharge port 7. There is no need to stop the machine for screening, and the ball milling of materials can be carried out continuously. The rotating drum 4 is equipped with a liner for carrying materials and rotating the grinding balls 8 to reach a suitable height.

[0028] In this embodiment, the screening component 5 includes a fixing member 51 symmetrically arranged inside the rotating drum 4. A spring 53 is provided inside the fixing member 51. A screening member 52 is arranged in the middle of the symmetrically arranged fixing member 51. Adjusting members 54 are fixedly connected to both sides of the screening member 52. An installation groove is opened inside the fixing member 51. One end of the spring 53 is fixedly installed inside the installation groove, and the other end is fixedly connected to the end of the adjusting member 54 away from the screening member 52. The fixing member 51 is slidably connected to the installation groove.

[0029] Specifically, when material impacts the surface of the screening element 52, the force on the screening element 52 compresses the spring 53 through the adjusting element 54. At this time, the kinetic energy of the screening element 52 is converted into the elastic potential energy of the spring 53. When the spring 53 returns to its deformed state, the potential energy is converted back into the kinetic energy of the screening element 52, forming a reciprocating motion. This energy conversion causes the screening element 52 to produce periodic vibrations, such as... Figure 4 As shown, the sliding displacement of the adjusting member 54 in the mounting groove is greater than the elastic adjustment distance of the screening member 52, so as to ensure that the adjusting member 54 and the fixed member 51 always maintain a sealed state, wherein the size of the screening hole opened by the screening member 52 is the size of the qualified material.

[0030] In this embodiment, the bottom end of the drive assembly 2 is fixedly connected to the base plate 1, and the two ends of the rotating drum 4 are rotatably connected to the bearing seats 3. The bottom end of the bearing seats 3 is fixedly installed on the upper end of the base plate 1. The two ends of the rotating drum 4 are respectively provided with a feed port 6 and a discharge port 7, which pass through the bearing seats 3 and are fixedly connected to the rotating drum 4.

[0031] Specifically, such as Figure 1 As shown, the drive assembly 2 includes a geared motor as a power source and a gear set for transmission. The large gear is fixedly mounted on the outside of the rotating drum 4, and the small gear is transmitted through the geared motor and meshes with the large gear. The geared motor generally achieves a certain speed reduction by using the small gear on the input shaft of the gear reducer (or gearbox) to drive the large gear through the electric motor, internal combustion engine, or other high-speed power source. By using a multi-stage structure, the speed can be greatly reduced, thereby increasing the output torque of the geared motor. Its core "power amplification and speed reduction" function is to achieve the purpose of speed reduction by using gear transmission at each stage. The reducer is composed of gear pairs at each stage. At the same time, the drive assembly 2 can also use any other device that can achieve the same effect.

[0032] Example 2: In this example, as Figure 7As shown, the ball milling section 41 can be configured as a first processing section 411 and a second processing section 412 by the screening component 5. The material processed by the second processing section 412 is smaller than the material processed by the first processing section 411. The size of the screening holes inside the screening component 5 between the first processing section 411 and the second processing section 412 is the same as the size of the material to be processed by the second processing section 412, and the size of the screening holes is larger than the size of the screening holes inside the screening component 5 between the collection section 42 and the ball milling section 41. By classifying and screening, the screening efficiency of qualified materials can be further improved, and excessive crushing can be avoided, which would lead to a decrease in the uniformity of internal antibacterial agent dispersion.

[0033] Working principle: The antibacterial agent powder and amino molding compound are kneaded and processed by the staff and then injected into the ball milling section 41 inside the rotating drum 4 through the feed port 6. The rotating drum 4 is then driven to rotate by the drive component 2, which in turn causes the grinding balls 8 inside the rotating drum 4 to rotate with the material. The grinding balls 8 are brought to a certain drop position by the liner set inside the rotating drum 4 and then dropped, thereby ball milling the material.

[0034] When some materials are processed to the appropriate size, they are screened by the screening component 5 and collected in the collection section 42 for subsequent discharge. At the same time, as the rotating drum 4 rotates, some materials inside the ball mill 41 will collide with the screening component 52, which will cause the screening component 52 to elastically adjust and vibrate, preventing materials from clogging the screening holes of the screening component 52 and affecting the subsequent discharge of materials. By discharging the materials processed to the qualified size inside the ball mill 41 in real time, it is prevented from being over-grinded, thereby improving the uniformity of the distribution of antibacterial agents inside the materials.

[0035] Next, when the qualified material collected inside the collection section 42 reaches the specified size, the qualified material is discharged through the discharge port 7. The whole process does not require stopping the machine and the material can be continuously ball-milled.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
