Description

Technical Field

[0001] The utility model relates to the technical field of masterbatch manufacturing, in particular to a heat mixer for masterbatch manufacturing. Background Art

[0002] Masterbatch is a plastic colorant. In today's society, masterbatch coloring is the most commonly used method of plastic coloring. Masterbatch is made of three main components: pigment, carrier and additive, which are well dispersed and mixed. The carrier is usually a resin that can wet and disperse the colorant well and has good compatibility. In the manufacturing process of masterbatch, hot mixer is indispensable.

[0003] During the working process of the hot mixer, through the impact, shearing, scattering and raw material friction of the blades, the hot mixer can follow the terminal temperature ladder specified in the standard and carry out product standards such as homogenization, macromolecularization and pre-plasticization.

[0004] Although existing heat mixers can produce masterbatches in large batches and meet market supply needs, their production efficiency is relatively low due to the relatively slow speed at which heat is generated by friction. In addition, during the mixing process, due to uneven heating, the raw materials at the edge of the machine may not be heat-mixed, further reducing production efficiency.

[0005] Therefore, we need to develop a heat mixer for masterbatch manufacturing that can quickly mix raw materials and allow the raw materials to be fully heated for heat mixing. Utility Model Content

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Example 1

[0026] A heat mixer for masterbatch production, such as Figure 1-Figure 3As shown, it includes a fixed frame 1, a mixing tank 2, a servo motor 3, a rotating wheel 4, a belt 5, a screw rod 6, a support column 7, a shell 8, a blower 9, an air pipe 10, a heating pipe 11, a hot air mesh cover 12, a feed hopper 13 and a discharge port 14. The mixing tank 2 is installed above the fixed frame 1, and two support columns 7 are installed above the inside of the mixing tank 2. The screw rod 6 is rotatably installed between the support columns 7. The screw rod 6 is used to move the raw materials. The servo motor 3 is installed on the right side of the mixing tank 2. The servo motor 3 is used to provide a power source. The top of the screw rod 6 and the top of the coupling of the servo motor 3 are connected to the rotating wheel 4, and the belt 5 is wound between the rotating wheels 4. The shell 8 is installed on the top of the mixing tank 2. The outer shell 8 is above the two wheels 4, and a blower 9 is installed on the right side of the fixed frame 1. The blower 9 is used to generate airflow. An air duct 10 is installed in the upper middle of the right side of the fixed frame 1. The bottom of the air duct 10 is connected with the blower 9. A heating pipe 11 is installed on the air duct 10. The heating pipe 11 is used to heat the airflow. The air duct 10 is connected with the mixing tank 2. A hot air mesh cover 12 is installed below the air duct 10. More preferably, the lower middle part of the mixing tank 2 is funnel-shaped for fully hot mixing the raw materials. A feed hopper 13 is installed at the lower left side of the mixing tank 2, and a discharge port 14 is installed at the lower front side of the mixing tank 2. The discharge port 14 is cylindrical, which is convenient for moving the processed masterbatch products to the outside world.

[0027] When people need to process and produce masterbatch, the existing heat mixer generates heat relatively slowly by friction, and the heating is uneven. Therefore, people can use this equipment to process and produce masterbatch by heat mixing. First, the raw materials are put into the feed hopper 13, and the raw materials move downward along the feed hopper 13 to the bottom of the screw rod 6. Then, the blower 9 is started, the blower 9 generates airflow, the heating pipe 11 heats the airflow, and the airflow enters and moves along the air delivery pipe 10 into the hot air net cover 12. Then, the servo motor 3 is started, and the output shaft of the servo motor 3 drives the right wheel 4 to rotate, and the right wheel 4 is driven by the belt 5. The middle wheel 4 rotates, and the middle wheel 4 drives the screw rod 6 to rotate, and the screw rod 6 drives the raw material to rotate and move upward. When the raw material moves to the top of the screw rod 6, it falls downward into the hot air mesh cover 12 and is dispersed into particles by the hot air mesh cover 12. At the same time, the raw material contacts the hot air and is hot-mixed and processed into masterbatch. Finally, the masterbatch moves along the inner wall of the mixing tank 2 to the discharge port 14, and then moves to the outside along the discharge port 14. When the raw material does not need to be hot-mixed, turn off the servo motor 3 and turn off the blower 9. In addition, the fixed frame 1 is used to fix the equipment, and the support column 7 is used to fix the screw rod 6.

[0028] Example 2

[0029] On the basis of Example 1, Figure 4-Figure 6As shown, it also includes a support frame 15, a material frame 16, a guide rod 17, a slide plate 18, a first protrusion 1801, an elastic member 19, a second protrusion 29, a blocking rod 28 and a handle 30. Two support frames 15 are installed on the left side below the fixed frame 1, and a material frame 16 is installed between the support frames 15 above. The support frame 15 is L-shaped and is used to better fix the material frame 16. The material frame 16 is used to place the raw material container. The bottom of the material frame 16 is in contact with the feed hopper 13. Guide rods 17 are installed on both the front and rear sides of the upper left side of the material frame 16. A slide plate 18 is slidably installed between the guide rods 17. The front and rear sides of the slide plate 18 are respectively connected to the top of the adjacent guide rods 17 with elastic members 19. Twelve first protrusions 1801 are evenly installed on the bottom of the slide plate 18. The first protrusion 1801 is used to fix the raw material container. A handle 30 is installed in the middle of the left side of the slide plate 18. The handle 30 is used to facilitate the movement of the slide plate 18. There are five second protrusions 29 below the material frame 16, and a blocking rod 28 is installed on the right side of the material frame 16.

[0030] In order to facilitate the feeding of raw materials, first, the handle 30 is moved upward, and the handle 30 drives the slide plate 18 to move upward along the guide rod 17. At this time, the elastic member 19 is deformed, and the container with raw materials is placed on the material frame 16. Then, the handle 30 is no longer moved, and the elastic member 19 is reset downward to drive the slide plate 18 to move downward. The slide plate 18 drives the first protrusion 1801 to move downward, and the first protrusion 1801 contacts and fixes the container. Next, the container opening is opened. Since the second protrusion 29 has the function of buffering the raw materials, the raw materials will enter the feed hopper 13 at a uniform speed downward. When the container does not need to be fixed, the handle 30 is moved upward to make the first protrusion 1801 detach from the container. The support frame 15 is used to fix the material frame 16, and the blocking rod 28 is used to prevent the container from falling into the feed hopper 13.

[0031] like Figure 4 , Figure 6 and Figure 7 As shown, it also includes an opening and closing door 20, a slide rail 21, a rack 22, a gear 23, a connecting rod 24, a turntable 25, a block 26, and a torsion spring 27. A slide rail 21 is installed at the middle and lower left side of the mixing tank 2, and an opening and closing door 20 is slidably installed below the slide rail 21. The opening and closing door 20 is used to block the raw materials. A connecting rod 24 is rotatably installed between the front and rear sides of the left side of the fixed frame 1, a turntable 25 is installed at the front end of the connecting rod 24, and three gears 23 are installed at the front and rear of the connecting rod 24. A block 26 is rotatably installed at the front left side of the fixed frame 1. The block 26 is used to fix the opening and closing door 20, and the block 26 is connected to the fixed frame 1 with a torsion spring 27. Two racks 22 are symmetrically installed at the front and rear of the left side of the opening and closing door 20. The rack 22 is used to drive the opening and closing door 20 to move, and the gears 23 are respectively meshed with the adjacent racks 22.

[0032] In order to achieve intermittent feeding, in the initial state, the bottom of the opening and closing door 20 is in contact with the feed hopper 13, and the opening and closing door 20 prevents the raw materials from entering the feed hopper 13. When the opening and closing door 20 needs to be opened, first, the turntable 25 is rotated, and the turntable 25 drives the connecting rod 24 to rotate, and the connecting rod 24 drives the gear 23 to rotate. At this time, the torsion spring 27 is deformed, and the two middle gears 23 are respectively engaged with the rack 22, and the two middle gears 23 respectively drive the adjacent racks 22 to move, and the rack 22 drives the opening and closing door 20 to move along the slide rail 21, and the bottom of the opening and closing door 20 is separated from the feed hopper 13, and the raw materials enter the feed hopper 13. Subsequently, the turntable 25 is no longer rotated. At this time, due to the action of gravity, the opening and closing door 20 moves downward, and the racks 22 respectively drive the adjacent gears 23 to rotate in the opposite direction, and the two rear gears 23 are respectively engaged with the racks 22. The gear 23 drives the connecting rod 24 to rotate in the opposite direction. At this time, the torsion spring 27 is reset, and the torsion spring 27 drives the block 26 to rotate. The block 26 is engaged with the front gear 23, so that the front gear 23 stops rotating. The front gear 23 makes the connecting rod 24, the two middle gears 23 and the turntable 25 no longer move, and the two middle gears 23 make the rack 22 no longer move, thereby further fixing the opening and closing door 20. When the opening and closing door 20 needs to be closed, the block 26 is rotated in the opposite direction so that the block 26 is disengaged from the front gear 23, and the opening and closing door 20 moves downward along the slide rail 21. When the block 26 is engaged with the front gear 23 again, the block 26 is rotated in the opposite direction again, so that the opening and closing door 20 continues to move downward until the bottom of the opening and closing door 20 contacts the feed hopper 13.

The description of the above embodiments is only used to help understand the method of the present application and its core idea.
