[0002] Masterbatch refers to a plastic colorant made by well-dispersing a high proportion of pigments or additives with thermoplastic resins. The selected resin has good wetting and dispersing effects on the colorant and has good compatibility with the colored material. The main components of masterbatch are colorant, carrier and dispersant. Masterbatch coloring has the advantages of high dispersibility, chemical stability, pollution-free and easy use. The production of masterbatch can be divided into raw material preparation, mixing, melting, granulation, drying, screening and packaging. In the process of masterbatch processing, different plastic particles usually need to be mixed in a certain proportion and stirred evenly, so a mixer is used.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0019] like Figure 1-4 As shown, a mixer for preparing flame-retardant masterbatch proposed in one embodiment of the utility model comprises a bottom plate 1, characterized in that: two support blocks 2 are symmetrically distributed and fixedly installed on the top of the bottom plate 1, a mixing barrel 3 is fixedly installed between the two support blocks 2, the bottom of the mixing barrel 3 is conical, a liftable barrel cover 301 is arranged on the top of the mixing barrel 3, a feed pipe 302 is arranged on the barrel cover 301, a discharge pipe 303 is arranged on the bottom of the mixing barrel 3, a solenoid valve 304 is also arranged on the discharge pipe 303, a stirring component 4 is arranged on the barrel cover 301, and a cleaning component 5 is arranged on the stirring component 4.

[0020] like Figure 1 As shown, in some embodiments, an electric push rod 6 is fixedly installed on the top of the two support blocks 2, and two fixed plates 7 are symmetrically fixedly installed on the outer surface of the barrel cover 301. The bottoms of the two fixed plates 7 are fixedly connected to the telescopic ends of the electric push rod 6. When in use, the electric push rod 6 can be started, and the electric push rod 6 pushes the two fixed plates 7 to move upward synchronously, and at the same time drives the barrel cover 301 to move upward, so as to open the barrel cover 301, which is convenient for the staff to check whether there is any masterbatch remaining in the mixing barrel 3 or observe the mixing effect of the masterbatch, and it is also convenient for the staff to install the cleaning component 5.

[0021] like Figure 2 As shown, in some embodiments, the stirring component 4 includes a servo motor 41 fixedly mounted on the top of the barrel cover 301, and a rotating rod 42 is fixedly mounted on the output shaft of the servo motor 41. One end of the rotating rod 42 passes through the barrel cover 301 and extends into the mixing barrel 3. A plurality of stirring rods 43 are fixedly mounted on the outer surface of the rotating rod 42. The stirring component 4 can automatically stir and mix the masterbatch in the mixing barrel 3.

[0022] like Figure 4As shown, in some embodiments, the cleaning component 5 includes a cleaning plate 51 installed on one end of the plurality of stirring rods 43 through a snap-on structure 8, and the number of the cleaning plates 51 is two, and bristles 52 are provided on one side of the two cleaning plates 51, and the bristles 52 are in contact with the inner wall of the mixing barrel 3. When the mixing barrel 3 is not in use, the cleaning component 5 can clean the inner wall of the mixing barrel 3 to prevent the masterbatch from adhering to the inner wall of the mixing barrel 3 and affecting the mixing of the next batch of masterbatch.

[0023] like Figure 3 As shown, in some embodiments, the snap-in structure 8 is a slot that is opened on the plurality of stirring rods 43, and one end of the two cleaning plates 51 is respectively inserted into the slot. The snap-in structure 8 facilitates the disassembly and replacement of the cleaning plates 51. When there is no need to clean the inner wall of the mixing barrel 3, a cleaning plate 51 without bristles 52 can be installed in the slot to seal the slot to prevent the masterbatch from clogging the slot. At the same time, the masterbatch in the mixing barrel 3 can be stirred, and the masterbatch can be prevented from adhering to the inner wall of the mixing barrel 3.

[0024] like Figure 1 and Figure 2 As shown, in some embodiments, a purification component 9 is provided on one of the fixed plates 7, and the purification component 9 includes an air pump 91 fixedly mounted on the top of one of the fixed plates 7, a first hose 92 is fixedly mounted on the air inlet end of the air pump 91, and the first hose 92 passes through the barrel cover 301, and a second hose 93 is fixedly mounted on the air outlet end of the air pump 91, and one end of the second hose 93 is connected to a purification box 94, and the purification box 94 is fixedly mounted on the top of the bottom plate 1. The purification component 9 can absorb the odor generated during the mixing of the masterbatch into the purification box 94 for purification, so as to avoid the generated gas being directly discharged into the air, thereby affecting the air quality.

[0025] like Figure 2 As shown, in some embodiments, the purification box 94 is filled with a purifier, and the purifier can purify the special gas generated when the masterbatch is mixed.

[0026] Working principle: When in use, pour the masterbatch raw material into the mixing barrel 3 through the feed pipe 302, and then start the servo motor 41. The servo motor 41 drives the rotating rod 42 to rotate, thereby driving the multiple stirring rods 43 to rotate synchronously, and then fully stir and mix the masterbatch in the mixing barrel 3. At the same time, start the vacuum pump 91. The vacuum pump 91 sucks the gas generated when the masterbatch is stirred into the first hose 92, and then sucks it into the purification box 94 through the second hose 93. The purifier filled in the purification box 94 purifies the gas and finally discharges it into the air. Finally, open the solenoid valve 304 to discharge the mixed masterbatch through the discharge pipe 303. When the mixing barrel 3 needs to be cleaned, start the electric push rod 6. The rod 6 pushes the two fixed plates 7 to move upward, and at the same time pushes the barrel cover 301 and the stirring assembly 4 installed on the barrel cover 301 to move upward until the stirring assembly 4 is completely moved out of the mixing barrel 3. Then the staff can clamp the cleaning plate 51 with bristles 52 in the slots provided on the multiple stirring rods 43, and then drive the barrel cover 301 and the stirring assembly 4 to move downward again through the electric push rod 6 until the barrel cover 301 returns to its original position. At this time, start the servo motor 41, and the servo motor 41 drives the rotating rod 42 to rotate, thereby driving the multiple stirring rods 43 to rotate, and then driving the cleaning plate 51 to rotate, so that the bristles 52 arranged on one side of the cleaning plate 51 clean the inner wall of the mixing barrel 3. The structure is simple and the operation is convenient.

[0027] Finally, the most important contribution of the present invention is that the stirring component 4 can stir and mix the masterbatch in the mixing barrel 3, and when not in use, the inner wall of the mixing barrel 3 can be cleaned by the cleaning component 5 to prevent the masterbatch from adhering to the inner wall of the mixing barrel 3, thereby affecting the stirring and mixing of the next batch of masterbatch. In addition, the purification component 9 can also absorb and purify the gas generated when the masterbatch is stirred and mixed, avoiding direct discharge into the air and affecting the air quality, effectively solving the problems mentioned in the background technology, and having certain practicality.

[0028] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
