Description

Technical Field

[0001] This utility model belongs to the field of material production technology, specifically a vibrating screening device for material production. Background Technology

[0002] Epoxy resin compositions are multi-component materials composed of epoxy resin, curing agent, filler, etc., and are widely used in adhesives, coatings, composite materials and electronic packaging.

[0003] In the production process of epoxy resin compositions, it is necessary to remove impurities from the materials. Usually, screening is required during the production process. Commonly used screening devices use the principle of vibration to screen and remove impurities from the materials. Vibrating screening equipment usually consists of a screen box, a vibrating motor, a screen, a shock absorption device, and a transmission device. The vibrating motor provides the vibration source, causing the screen box to make periodic movements. The linear vibration method continuously throws the material up and down, and the material moves along the screen surface to the discharge port.

[0004] During the screening process of epoxy resin materials, the materials themselves have a certain degree of viscosity and vary in size. When the fine particles are similar in size to the sieve holes, the fine particles are easily stuck in the sieve holes. Due to the viscosity of the materials, they are prone to clogging in the sieve, resulting in a decrease in material screening efficiency.

[0005] Therefore, this utility model provides a vibratory screening device for material production. Utility Model Content

[0023] like Figures 1 to 4As shown, a material production vibrating screening device according to an embodiment of the present invention includes a body 1; a base 10 is fixedly connected to the bottom of the body 1; a top cover 11 is installed on the top of the body 1; a screen plate 12 is fixedly connected to the middle of the body 1; a feed hopper 13 is provided at one end of the top of the body 1; a discharge hopper 14 is provided at the end of the body 1; two first drivers 15 are installed at the end of the body 1; the output end of the first driver 15 passes through the middle of the body 1; two fixing frames 16 are fixedly connected to the inner side wall of the body 1; the two fixing frames 16 are arranged opposite to each other; the two fixing frames 16... A screw 17 is rotatably connected to the middle of a fixed frame 16, located at the bottom of the screen plate 12. The screw 17 passes through one end of a first driver 15. The output end of the first driver 15 is fixedly connected to the end of the screw 17. A square nut 18 is installed in the middle of the screw 17. A fixing rod 19 is fixedly connected to the ends of the two square nuts 18. A rotating cylinder 111 is rotatably connected to the middle of the fixing rod 19. Multiple brush strips 112 are fixedly connected to the middle of the rotating cylinder 111. During operation, the top cover 11 is installed on the top of the machine body 1, and the material enters the machine body 1 through the feed hopper 13. The vibrating motor causes vibration inside the machine body 1. During the vibration screening of materials, the two first drivers 15 are turned on, causing the output end of the first driver 15 to drive the lead screw 17 to rotate in the middle of the fixed frame 16. During the rotation of the lead screw 17, the square nut 18 moves in the middle of the fixed frame 16. At this time, the end of the brush 112 is inserted into the hole in the middle of the screen plate 12. As the square nut 18 moves, the rotating cylinder 111 rotates in the middle of the fixed rod 19. The brush 112 clears the screen plate 12 during the screening of materials. The brush 112 reciprocates through the first driver 15. The materials screened by the screen plate 12 are discharged through the discharge bin 14 as they vibrate. The rotating brush 112 can clean the screen holes of the screen plate 12 in real time through the above structure, reduce the blockage of materials during the vibration screening of the screen plate 12, break the agglomeration and accumulation of materials in the screen plate 12, promote the dispersion and flow of materials during the screening process, and enable the materials to pass through the screen plate 12 smoothly, keeping the screen holes unobstructed, thereby maintaining the screening accuracy and improving product quality.

[0024] like Figure 1 and Figure 2As shown, a second driver 2 is installed at the end of the feeding hopper 13; the output end of the second driver 2 passes through the middle of the feeding hopper 13; a rotating shaft 21 is fixedly connected to the output end of the second driver 2; multiple baffles 22 are fixedly connected to the middle of the rotating shaft 21; the multiple baffles 22 are evenly distributed; during operation, when the material enters the feeding hopper 13, the second driver 2 is controlled to rotate its output end, and the output end of the second driver 2 drives the rotating shaft 21 to rotate inside the feeding hopper 13, intercepting the material through the baffles 22. As the multiple baffles 22 rotate, the material is quantitatively brought into the machine body 1. Through the above structure, the amount of material entering the machine body 1 can be precisely controlled, reducing the decrease in screening efficiency caused by too much or too little material. By precisely controlling the amount of material fed, the accumulation of material in the middle of the screen plate 12 is effectively reduced, maintaining the continuity and stability of the screening process.

[0025] like Figure 1 and Figure 4 As shown, an air pump 3 is installed on the top of the discharge hopper 14; a first connecting pipe 31 is fixedly connected to the middle of the air pump 3; a collection box 32 is fixedly connected to the end of the first connecting pipe 31; the collection box 32 is fixedly connected to the top of the discharge hopper 14; a filter plate 33 is fixedly connected to the middle of the collection box 32; a water inlet pipe 34 is fixedly connected to the top of the collection box 32; a second connecting pipe 35 is fixedly connected to the side wall of the collection box 32; the second connecting pipe 35 penetrates the top of the discharge hopper 14; a dust suction pipe 36 is fixedly connected to the end of the second connecting pipe 35; the dust suction pipe 36 is fixedly connected inside the discharge hopper 14; multiple dust suction holes 37 are opened in the middle of the dust suction pipe 36; during operation, some water is injected into the collection box through the water inlet pipe 34. Internal storage 32: When materials are screened and enter the discharge hopper 14, dust in the materials is discharged into the discharge hopper 14. The vacuum pump 3 is turned on, and the dust entering the middle of the discharge hopper 14 is sucked into the collection box 32 through multiple dust suction pipes 36. The filter plate 33 intercepts the particles, and the particles enter the water. The filtered dust is discharged through the vacuum pump 3. Through the above structure, a large amount of dust generated during the screening process can be collected in a unified manner, and the dust at the discharge point can be continuously cleaned. The airflow carrying dust is filtered to reduce the amount of dust discharged from the discharge hopper 14 with the materials, thereby reducing the pollution of the working environment by dust emissions.

[0026] like Figure 4As shown, two fixing plates 4 are fixed to the inner wall of the discharge bin 14; the two fixing plates 4 are arranged opposite each other; an installation groove 41 is opened in the middle of the fixing plate 4; a magnetic block 42 is fixed in the middle of the installation groove 41; a magnetic plate 43 is magnetically connected to the middle of the magnetic block 42; during operation, when the screened material is discharged through the bottom of the discharge bin 14, it passes through the surface of the magnetic plate 43, and the magnetic plate 43 adsorbs the metal impurities in the material. After the material is screened, the magnetic plate 43 is separated from the magnetic block 42, and the metal impurities on the surface of the magnetic plate 43 can be further processed. Through the above structure, the ferromagnetic impurities in the material can be adsorbed when the material is discharged, reducing the waste generated by the ferromagnetic impurities in the material, and the magnetic plate 43 can be cleaned and replaced regularly. The maintenance process is simple and convenient, and the recovered iron impurities can be reused, improving the utilization rate of resources.

[0027] like Figure 2 and Figure 3 As shown, multiple diversion plates 5 are fixed to the top of the screen plate 12; the multiple diversion plates 5 are set at the corresponding feed bins 13; during operation, when the material falls onto the screen plate 12 through the baffle 22, the material is evenly separated by the multiple diversion plates 5, so that the material is evenly distributed on the surface of the screen plate 12. Through the above structure, the material entering the second drive 2 can be evenly dispersed, reducing the local accumulation of material in the screen plate 12, allowing the material to contact the screen surface of the screen plate 12 more comprehensively, improving the screening speed and reducing the screening time.

[0028] like Figure 2 As shown, a sealing plate 6 is fixedly connected to the bottom of the top cover 11; the sealing plate 6 is fixedly connected to the inside of the machine body 1; during operation, when the top cover 11 is installed on the top of the machine body 1, the sealing plate 6 seals the top cover 11 and the machine body 1. The above structure enables the top cover 11 and the machine body 1 to form a tighter closed space, effectively reducing the leakage of dust generated during the screening process from the gap between the machine body 1 and the top cover 11, preventing material dust from escaping, and maintaining a clean and hygienic working environment.

[0029] like Figure 2 As shown, a sound insulation plate 7 is provided on the top of the top cover 11; the sound insulation plate 7 is fixed to the top of the top cover 11; during operation, the sound insulation plate 7 absorbs the noise generated inside the machine body 1 during the material screening process. The above structure can absorb the noise generated by the machine body 1 during the material vibration screening process, reduce the transmission of noise, and effectively reduce noise pollution to the surrounding environment.

[0030] During operation, the top cover 11 is installed on top of the machine body 1. The material enters the machine body 1 through the feed hopper 13. The vibration motor causes vibration inside the machine body 1. During the material vibration screening process, the two first drivers 15 are turned on, causing the output end of the first driver 15 to drive the lead screw 17 to rotate in the middle of the fixed frame 16. As the lead screw 17 rotates, it drives the square nut 18 to move in the middle of the fixed frame 16. At this time, the end of the brush strip 112 passes through the hole in the middle of the screen plate 12. As the square nut 18 moves, the rotating cylinder 1... 11 rotates in the middle of the fixed rod 19, and the brush strip 112 clears the sieve plate 12 during the material screening process. The brush strip 112 reciprocates through the first driver 15. The material screened by the sieve plate 12 vibrates and is discharged through the discharge bin 14. When the material enters the feed bin 13, the second driver 2 is controlled to rotate its output end. The output end of the second driver 2 drives the rotating shaft 21 to rotate inside the feed bin 13, and the material is intercepted by the baffle 22. As multiple baffles 22 rotate, the material is quantitatively carried into the machine body 1. Part of the water is injected into the collection box 32 through the inlet pipe 34 for storage. When the material is screened and enters the discharge hopper 14, the dust in the material is discharged into the discharge hopper 14. The vacuum pump 3 is turned on, and the dust entering the middle of the discharge hopper 14 is sucked into the collection box 32 through multiple suction pipes 36. The filter plate 33 intercepts the particles, and at the same time, the particles enter the water. The filtered dust is discharged by the vacuum pump 3. When the screened material is discharged through the bottom of the discharge hopper 14, it passes through the surface of the magnetic plate 43. The metal impurities in the material are adsorbed. After the material screening is completed, the magnetic plate 43 is separated from the magnetic block 42, and the metal impurities on the surface of the magnetic plate 43 can be further processed. When the material falls onto the screen plate 12 through the baffle 22, the material is evenly separated by multiple diversion plates 5, so that the material is evenly distributed on the surface of the screen plate 12. When the top cover 11 is installed on the top of the machine body 1, the sealing plate 6 seals the top cover 11 and the machine body 1. During the material screening process, the sound insulation plate 7 absorbs the noise generated inside the machine body 1.
