Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch cleaning, in particular to a masterbatch production dust cleaning device. Background Art

[0002] Masterbatch is a polymer material, usually composed of pigments, dispersants and carrier resins. Its function is to disperse the pigments evenly in the resin to obtain plastic products with specific colors and properties. Masterbatch can be used in plastics, rubber, coatings and other fields.

[0003] However, in the prior art, a lot of dust will be mixed in the masterbatch product after it is produced. The common masterbatch dust cleaning device shakes the masterbatch and cleans the dust with wind power. Although the existing dust cleaning device can shake the masterbatch, most of the masterbatch is still accumulated at the bottom of the device. The gaps between the masterbatch are small, and the dust cleaning effect is not very ideal. Therefore, we propose a masterbatch production dust cleaning device. Utility Model Content

[0004] The utility model provides a dust cleaning device for masterbatch production, which solves the above-mentioned technical problems.

[0006] Preferably, the power mechanism includes a fixing frame fixedly mounted on the upper end surface of the shell, a first motor is vertically fixedly mounted on the lower end surface of the fixing frame, and an output shaft of the first motor rotates through the shell and is fixedly connected to the upper end of the conveying screw.

[0007] Preferably, the driving mechanism includes a second motor fixedly mounted laterally on the outer side wall of the shell, the output shaft of the second motor rotates through the side wall of the shell, and two helical gears are fixedly mounted on the output shaft of the second motor, and the two helical gears are respectively meshed with the first helical gear ring and the second helical gear ring.

[0009] Preferably, a closed ring is fixedly mounted on the inner wall of the shell, the closed ring is slidably engaged with the outer surface of the connecting ring, and the output shaft of the second motor rotates and passes through the closed ring.

[0010] Preferably, a funnel-shaped feed port is fixedly mounted on the upper end surface of the shell, and a sealing cover is rotatably mounted on the upper end surface of the feed port.

[0011] The beneficial effects of the utility model are:

[0012] By setting a fixed cylinder to work with the conveying spiral, the masterbatch at the bottom of the shell is continuously transported upward, so that the masterbatch falls from the upper part of the shell and is dispersed by impact by the rotating dispersion disk and impact plate, so that the gaps between the masterbatch particles are larger, avoiding the accumulation of masterbatch, and cooperating with the exhaust fan for dust cleaning, the dust cleaning effect is more ideal. In addition, the dispersion disk and the impact plate cooperate to disperse the masterbatch particles. At the same time, the first bevel gear ring and the second bevel gear ring used to drive the dispersion disk and the impact plate to rotate respectively are indirectly controlled by the second motor, which reduces the use of power equipment and reduces equipment costs. At the same time, the first bevel gear ring and the second bevel gear ring rotate in opposite directions, which can promote the impact dispersion of the masterbatch by the dispersion disk and the impact plate.

[0022] The following is combined with Figure 1-5 The principles and features of the present invention are described, and the examples provided are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0023] like Figure 1-5As shown, the utility model is a dust cleaning device for masterbatch production, including a shell 1, the lower part of the shell 1 is funnel-shaped, which is convenient for the discharge of masterbatch, and a solenoid valve 2 is provided at the lower part of the shell 1. A fixed cylinder 3 is vertically fixedly installed on the top surface of the shell 1 through multiple vertically arranged connecting rods, and a conveying screw 4 is vertically arranged inside the fixed cylinder 3. The upper and lower ends of the conveying screw 4 extend to the outside of the fixed cylinder 3 respectively, and the conveying screw 4 is connected to a power mechanism. Two dispersion discs 5 are rotatably installed on the outer wall of the fixed cylinder 3, and the two dispersion discs 5 rotate synchronously. The dispersion discs 5 rotate and hit the masterbatch to promote the dispersion of the masterbatch. The two dispersion discs 5 are fixedly connected by multiple vertically arranged connecting rods. The lower end surface of the dispersion disc 5 located at the upper part is fixedly installed with a first oblique gear ring 6, and the inner wall of the shell 1 is slidably matched with a second oblique gear ring 7. The lower end face of the ring 7 is fixedly mounted with a connecting ring 8 which is slidably connected to the inner wall of the shell 1. The lower end face of the connecting ring 8 is vertically fixedly mounted with a plurality of impact plates 9 arranged at equal intervals. The first bevel gear ring 6 and the second bevel gear ring 7 are both connected to a driving mechanism. A dust adsorption mechanism is provided in the shell 1. The dust adsorption mechanism includes an exhaust fan 14 fixedly mounted on the upper end face of the fixing frame 10. The exhaust fan 14 is fixedly connected to the upper wall of the shell 1 through a plurality of L-shaped connecting pipes 15. A filter bag 16 is threadedly mounted on the air outlet end of the exhaust fan 14. A plurality of air inlet pipes 17 are fixedly connected at an angle at the lower part of the outer wall of the shell 1. A filter screen 18 is threadedly mounted on the end of the air inlet pipe 17, so that the filter screen 18 is easy to disassemble and clean. At the same time, the filter screen 18 is used to filter the air entering the device from the outside to reduce the entry of dust and debris into the shell 1.

[0024] Specifically, the power mechanism includes a fixing frame 10 fixedly mounted on the upper end surface of the shell 1, and a first motor 11 is vertically fixedly mounted on the lower end surface of the fixing frame 10. The output shaft of the first motor 11 rotates through the shell 1 and is fixedly connected to the upper end of the conveying screw 4. The first motor 11 adopts a servo motor that can rotate forward and reverse. The first motor 11 drives the conveying screw 4 to rotate in the opposite direction, which can drive the masterbatch to circulate in the shell 1 for dust cleaning. The first motor 11 drives the conveying screw 4 to rotate forward, which can drive the discharge.

[0025] More specifically, the driving mechanism includes a second motor 12 fixedly mounted laterally on the outer wall of the shell 1, and the output shaft of the second motor 12 rotates through the side wall of the shell 1. Two helical gears 13 are fixedly mounted on the output shaft of the second motor 12, and the two helical gears 13 are respectively engaged with the first helical gear ring 6 and the second helical gear ring 7. The first helical gear ring 6 and the second helical gear ring 7 are respectively engaged with the two helical gears 13. The first helical gear ring 6 is engaged with the corresponding upper part of the helical gear 13, and the second helical gear ring 7 is engaged with the corresponding lower part of the helical gear 13, so that the first helical gear ring 6 and the second helical gear ring 7 rotate in opposite directions, indirectly controlling the dispersion disk 5 and the impact plate 9 to rotate in opposite directions, promoting the dispersion of the masterbatch by the device, and the dust cleaning effect is more ideal.

[0026] Furthermore, a closed ring 19 is fixedly installed on the inner wall of the shell 1, and the closed ring 19 is slidably matched with the outer surface of the connecting ring 8. The output shaft of the second motor 12 rotates through the closed ring 19. The closed ring 19 cooperates with the connecting ring 8 to enclose the second bevel gear ring 7 to form a closed space, preventing dust from getting stuck in the lower part of the second bevel gear ring 7, which is more conducive to the collection and cleaning of dust.

[0027] Furthermore, a funnel-shaped feed port is fixedly mounted on the upper end surface of the shell 1, and a cover is rotatably mounted on the upper end surface of the feed port. The funnel-shaped feed port is provided to facilitate the insertion of the masterbatch.

[0028] Working principle:

[0029] When in use, the masterbatch is placed into the shell 1 through the feed port, the cover is closed, and the first motor 11, the second motor 12 and the exhaust fan 14 are controlled to start. The second motor 11 drives the motion screw 4 to rotate in the opposite direction, and the second motor 12 drives the two bevel gears 13 to rotate. The two bevel gears 13 respectively drive the first bevel gear ring 6 and the second bevel gear ring 7 to rotate, the first bevel gear ring 6 drives the dispersion disk 5 to rotate, and the second bevel gear ring 6 drives the installation plate 9 to rotate. The exhaust fan 14 drives the inlet and outlet air, and the external air enters from the inlet branch pipe 17 and is then discharged from the filter bag 16 through the connecting pipe 15. In this way, the conveying spiral 4 continuously moves the masterbatch at the lower part of the shell 1 upward from the fixed cylinder 3, and the masterbatch moves to the top of the fixed cylinder 3 and falls. When falling, it is beaten and dispersed by the dispersion disk 5 and the impact plate 9. At the same time, the exhaust fan 14 works to absorb the dust in the masterbatch and send it into the filter bag 16.

[0030] The above are only preferred embodiments of the present invention and do not constitute any form of limitation to the present invention. Any ordinary technician in this industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with this profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the scope of protection of the technical solution of the present invention.
