Abstract
Description
Technical Field
[0001] This utility model relates to the field of mixing equipment technology, specifically to a plastic granule mixer for preparing plastic buckets that facilitates uniform mixing. Background Technology
[0002] Plastic granule mixing equipment is a type of mechanical equipment specifically designed for the plastics processing industry. It is mainly used to uniformly mix plastic granules of different types, colors, or properties to ensure the consistency of the quality and performance of the final plastic products. Through the high-speed rotation or low-speed tumbling of the agitator inside the equipment, the plastic granules can be fully mixed in a closed mixing chamber, effectively avoiding the stratification and clumping of the granules.
[0003] In the production process of plastic buckets, it is necessary to mix plastic granules of different lengths to ensure that the plastic granules form the required plastic melt after melting. Most existing plastic granule mixing equipment is external and mixes plastic granules of multiple colors, usually in large batches. Therefore, when a large number of plastic granules are mixed at the same time, the mixing force is insufficient, making it difficult to mix all the granules fully. This results in some areas of plastic granules not being fully mixed, leading to color differences in some areas of the melted plastic later. Utility Model Content
[0004] The purpose of this invention is to provide a plastic granule mixer for preparing plastic buckets that facilitates uniform mixing, thus solving the problem of insufficient uniformity of plastic granule mixing when mixing a large number of plastic granules at a time in related technologies.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A plastic pellet mixer for preparing plastic buckets, which facilitates uniform mixing, includes a mixing chamber. A feeding box is fixedly installed at the bottom of the mixing chamber, and a top cover is fixedly installed at the top of the mixing chamber. Multiple feeding hoppers are fixedly installed on the top of the top cover. A motor is fixedly installed at the center of the top of the top cover, and the motor is electrically connected to an external main controller via a connecting wire. A base plate is fixedly installed between the mixing chamber and the feeding box. An outer cylinder is fixedly installed on the top of the base plate. An inner cylinder is movably installed on the top of the mixing chamber located inside the outer cylinder. A first stirring blade is fixedly installed at the bottom of the inner cylinder and is placed inside the feeding box.
[0007] Optionally, a discharge valve is fixedly installed at the bottom of the discharge box, and a connecting seat is fixedly installed at the bottom of the discharge valve;
[0008] Based on this, the entire device is installed at the feed point of the injection molding machine via a connecting seat, while the discharge valve controls the discharge amount.
[0009] Optionally, a plurality of first discharge channels are provided at the center of the bottom plate, and a guide hopper is fixedly installed on the top of the bottom plate, with the outer side of the guide hopper closely fitted to the inner side of the mixing tank;
[0010] Based on this, the plastic granules entering the mixing tank can be guided into the outer cylinder by the feed hopper.
[0011] Optionally, a plurality of first feed channels are provided at the lower inner side of the outer cylinder.
[0012] Optionally, an installation shaft is fixedly installed at the center of the bottom of the inner cylinder, and multiple second discharge slots are provided on the inner cylinder located around the installation shaft. The inner cylinder is rotatably mounted on the base plate via the installation shaft, and the bottom of the installation shaft extends through the base plate into the discharge box.
[0013] Optionally, a plurality of second feed channels are provided at the upper part of the inner side of the inner cylinder.
[0014] Optionally, a spiral conveying blade is fixedly installed on the outer side of the inner cylinder, and a plurality of second stirring blades are also fixedly installed on the inner cylinder located above the second feed trough. The second stirring blades pass through the space between the top cover and the outer cylinder and are placed in the cavity between the mixing box and the outer cylinder. The top of the inner cylinder is fixedly connected to the output end of the motor.
[0015] Based on this, by driving the inner cylinder to rotate by the motor, the plastic granules that have entered the outer cylinder can be transported into the inner cylinder, and discharged into the feeding box through the second discharge channel and the first discharge channel for secondary mixing and feeding.
[0016] Optionally, a sleeve is fixedly installed at the top center of the first stirring blade, and the sleeve is fixedly installed on the mounting shaft located inside the feed box. Reinforcing ribs are fixedly installed on both sides inside the first stirring blade.
[0017] Based on this, by using the first stirring blade, the inner cylinder can drive the first stirring blade to rotate in the feeding box, thereby further mixing the plastic granules temporarily stored in the feeding box and improving the uniformity of the plastic granule mixing.
[0018] The working principle and beneficial effects of this utility model are as follows:
[0019] In this invention, a top cover is provided between the mixing tank and the feeding box, and an outer cylinder and an inner cylinder are provided on the top cover. By rotating the inner cylinder and the first stirring blade by the motor, the plastic particles of different lengths can be mixed for the first time in the mixing tank. At the same time, the plastic particles that have been mixed in the mixing tank can be sent to the feeding box for secondary mixing. This improves the uniformity of the plastic particle mixing and allows the mixed plastic particles to be directly fed into the feeding box. Attached Figure Description

It includes a mixing box 1, a feeding box 2 fixedly installed at the bottom of the mixing box 1, a top cover 3 fixedly installed at the top of the mixing box 1, a plurality of feeding hoppers 4 fixedly installed at the top of the top cover 3, a motor 5 fixedly installed at the center of the top of the top cover 3, and the motor 5 is electrically connected to an external main controller through a connecting wire. A bottom plate 11 is fixedly installed between the mixing box 1 and the feeding box 2, an outer cylinder 6 is fixedly installed at the top of the bottom plate 11, and an inner cylinder 7 is movably installed on the top of the mixing box 1 located inside the outer cylinder 6. A first stirring blade 8 is fixedly installed at the bottom of the inner cylinder 7 and is placed inside the feeding box 2.
[0032] A discharge valve 9 is fixedly installed at the bottom of the discharge box 2, and a connecting seat 10 is fixedly installed at the bottom of the discharge valve 9. Based on this, the entire device is installed at the inlet of the injection molding machine through the connecting seat 10. The discharge valve 9 can control the discharge amount. Multiple first discharge channels 12 are opened at the center of the bottom plate 11, and a guide hopper 13 is fixedly installed at the top of the bottom plate 11. The outer side of the guide hopper 13 is tightly fitted with the inner side of the mixing box 1. Based on this, the plastic particles entering the mixing box 1 can be guided into the outer cylinder 6 through the guide hopper 13. Multiple first inlet channels 14 are opened at the lower inner side of the outer cylinder 6. An installation shaft 19 is fixedly installed at the center of the bottom of the inner cylinder 7. Multiple second discharge channels 16 are opened in the inner cylinder 7 located around the installation shaft 19. The inner cylinder 7 is connected to the outer cylinder 6 by the installation shaft. The mounting shaft 19 is rotatably mounted on the base plate 11, and the bottom of the mounting shaft 19 extends through the base plate 11 into the material box 2. Multiple second feeding channels 17 are opened at the upper part of the inner side of the inner cylinder 7. A spiral conveying blade 18 is fixedly installed on the outer side of the inner cylinder 7. Multiple second stirring blades 15 are also fixedly installed on the inner cylinder 7 above the second feeding channels 17. The second stirring blades 15 pass through the space between the top cover 3 and the outer cylinder 6 and are placed in the cavity between the mixing box 1 and the outer cylinder 6. The top of the inner cylinder 7 is fixedly connected to the output end of the motor 5. Based on this, the inner cylinder 7 is driven to rotate by the motor 5, which can transport the plastic particles that enter the outer cylinder 6 to the inner cylinder 7, and discharge them into the material box 2 through the second discharge channel 16 and the first discharge channel 12 for secondary mixing and discharge.
[0033] Example 2:
[0034] Reference Figures 3-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that a sleeve 20 is fixedly installed at the top center of the first stirring blade 8. The sleeve 20 is fixedly installed on the mounting shaft 19 located inside the feeding box 2. Reinforcing ribs 21 are fixedly installed on both sides of the first stirring blade 8. Based on this, by means of the setting of the first stirring blade 8, the first stirring blade 8 can be driven to rotate in the feeding box 2 by the inner cylinder 7, so as to further mix the plastic particles temporarily stored in the feeding box 2 and improve the uniformity of the plastic particle mixing.
[0035] It should be noted that this utility model is a plastic granule mixer for preparing plastic buckets, which facilitates uniform mixing. When mixing various types of plastic granules, different plastic granules can be conveyed uniformly and quantitatively into the corresponding feed hopper 4 via corresponding conveyors. The feed hopper 4 then conveys the plastic granules into the mixing chamber 1. Subsequently, the motor 5 starts and drives the inner cylinder 7 to rotate around the mounting shaft 19 within the outer cylinder 6. This causes the inner cylinder 7 to synchronously drive the outer spiral conveying blade 18 and the second stirring blade 15 to rotate, thereby mixing the plastic granules that have entered the mixing chamber 1 and the outer cylinder 6. Simultaneously, the plastic granules after the first mixing... The plastic granules are fed into the outer cylinder 6 through the bottom of the mixing tank 1 with the guide hopper 13 and the first feed channel 14. The plastic granules are then conveyed upward through the inner cylinder 7 and the first stirring blade 8 and enter the inner cylinder 7 through the second feed channel 17. After entering the inner cylinder 7, the plastic granules enter the discharge box 2 through the second discharge channel 16 and the first discharge channel 12. This allows the plastic granules after the first mixing to be temporarily stored in the discharge box 2 due to the control of the discharge speed. At the same time, the first stirring blade 8 performs a second mixing and stirring of the plastic granules temporarily stored in the discharge box 2, thereby preventing discharge blockage and further improving the mixing uniformity of plastic granules of different colors.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
