Abstract
Description
Technical Field
[0001] This utility model relates to the field of black masterbatch packaging technology, and in particular to a pneumatic conveying device for black masterbatch packaging. Background Technology
[0002] Black masterbatch is a raw material produced by processes such as injection molding of carbon black, carrier and additives. It is usually a cylindrical black body, such as a 2.2×2.8 cylindrical shape. It is high black and high gloss, easy to disperse, and can achieve a high gloss mirror effect. It is environmentally friendly, non-toxic, odorless and smokeless. The product surface is smooth and bright and the solid color is stable and tough. There will be no color spots or color lines. Black masterbatch is suitable for most thermoplastic resin injection molding, pelletizing, pressing, blown film, wire, pipe and other processes.
[0003] Pneumatic conveying devices are required when producing and packaging black masterbatch. However, traditional pneumatic conveying devices have a storage bin at the top for feeding. During conveying, the black masterbatch inside the traditional storage bin is prone to accumulation due to compression, which can cause blockages during feeding and affect the packaging process. Therefore, a pneumatic conveying device for black masterbatch packaging is needed to solve the above problems. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are: the pneumatic conveying device for packaging black masterbatch can vibrate the material box through the setting of the vibration structure during use, so that the material box is less likely to be blocked when feeding. In addition, the setting of the filter structure can filter the black masterbatch, thereby reducing impurities in the black masterbatch.
[0013] 1. By setting up a vibration structure, when packaging black masterbatch, the motor drives the impact column to move back and forth inside the guide sleeve through the cooperation between the fixed plate and the rotating plate. The top of the impact column hits the outside of the material box and vibrates the black masterbatch inside the material box, so that the black masterbatch inside the material box is less likely to be blocked when it is fed, thus completing the anti-blocking work.
[0014] 2. By incorporating a filtration structure, the filter frame and filter screen work together to filter the black masterbatch when it is poured into the hopper, thereby removing larger impurities and improving the quality of the black masterbatch during packaging. This completes the filtration process. Attached Figure Description

[0023] In a further preferred embodiment of this utility model, such as Figures 1-5 As shown: The filter structure 5 includes a filter frame 501, a baffle 502, a filter screen 503, a nut 504, and a fixing bolt 505. The fixing bolt 505 is fixed to the top of the material box 4. The filter frame 501 is installed on the outside of the fixing bolt 505. The nut 504 is installed on the top of the fixing bolt 505. The baffle 502 is installed on the top of the filter frame 501. The filter screen 503 is installed inside the filter frame 501. The nut 504 is sleeved on the outside of the fixing bolt 505. The nut 504 and the fixing bolt 505 form a threaded connection.
[0024] Specifically, in this embodiment: when packaging the black masterbatch, the black masterbatch needs to be poured into the inside of the material box 4 first. Before pouring, the filter frame 501 is installed on the top of the material box 4. After installation, the nut 504 is fixed to the outside of the fixing bolt 505 to complete the fixing of the filter frame 501. After the filter frame 501 is fixed, the filter screen 503 can be used to filter the black masterbatch, thereby screening out larger impurities in the black masterbatch, improving the quality of the black masterbatch, and thus completing the filtration of the black masterbatch.
[0025] In a further preferred embodiment of this utility model, such as Figures 1-5 As shown: The vibration structure 9 includes a guide sleeve 901, a fixed disk 902, an impact column 903, a hinged connecting frame 904, a movable sleeve 905, a rotating disk 906, and a fixed column 907. The guide sleeve 901 is fixed to one side of the bottom of the material box 4. The fixed disk 902 is fixed to the outside of the output end of the motor 8. The rotating disk 906 is movably mounted on one end of the conveying device body 2. A fixed column 907 is fixed to one side of the rotating disk 906. A movable sleeve 905 is installed on the outside of the fixed column 907. A hinged connecting frame 904 is installed at the top of the device, and an impact column 903 is installed at the top of the hinged connecting frame 904. The fixed plate 902 is connected to the rotating plate 906 via a belt. One end of the rotating plate 906 is movably connected to one side of the conveying device body 2.

[0026] Specifically, in this embodiment, when it is necessary to package the black masterbatch, the packaging bag is placed at the bottom of the discharge pipe 3. After it is placed, the external power supply is connected to start the motor 8. After the motor 8 is started, it will drive the impeller inside the negative pressure fan 6 to rotate rapidly and generate wind power, blowing air into the interior of the conveying device body 2. When the air flows inside the conveying device body 2, the valve under the material box 4 is opened through the solenoid valve 7, so that the black masterbatch falls into the interior of the conveying device body 2. The black masterbatch that falls into the interior of the conveying device body 2 will be carried by the flowing air through the discharge pipe 3 into the packaging bag to complete the packaging work.
[0027] After starting, the motor 8 will also drive the fixed disk 902 to rotate. When the fixed disk 902 rotates, it will drive the rotating disk 906 to rotate via the belt. When the rotating disk 906 rotates, it will drive the fixed column 907 to rotate. When the fixed column 907 rotates, through the cooperation between the movable sleeve 905 and the hinged connecting frame 904, it will drive the impact column 903 to reciprocate inside the guide sleeve 901. The impact on the outside of the material box 4 will generate a vibration force to vibrate the black masterbatch inside the material box 4, so that the black masterbatch is less likely to be blocked when it is fed into the material box 4, thus completing the anti-blocking work.
[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
