Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic particle mixing technology, and in particular to a plastic particle mixing mixer. Background Technology
[0002] In the plastics processing industry, the uniformity of plastic granule mixing directly affects the molding quality and appearance consistency of subsequent products. Therefore, plastic granule mixing machines are key equipment in the production process. Currently, most mainstream plastic granule mixing machines on the market use a single spiral stirring rod, straight plate stirring blades, or frame stirring frame as their core stirring structure. The stirring components are driven by a motor to make circular motions inside the mixing drum, thereby agitating and mixing the plastic granules.
[0003] However, the movement trajectory of the stirring components in this type of traditional mixing equipment is simple, mainly consisting of horizontal circular stirring. This makes it difficult to fully stir the plastic particles at different heights within the mixing drum. The upper and lower layers of particles are not mixed sufficiently, and some particles are even in a mixing dead zone for a long time. Ultimately, this results in insufficient uniformity of the mixture, affecting the product quality of subsequent injection molding, extrusion and other processing steps. Utility Model Content
[0004] The present invention aims to at least partially solve one of the problems existing in the prior art. To this end, the present invention proposes a plastic granule mixing and stirring machine.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A plastic granule mixing mixer includes a mixing drum and an end cap that covers the upper end of the mixing drum. A motor is installed at the bottom of the mixing drum, and the output shaft of the motor extends into the mixing drum and is provided with a mixing assembly. The mixing assembly includes a sleeve connected to the output shaft of the motor. Several transverse mixing plates are evenly distributed and spaced along the circumference of the outer wall of the sleeve. A V-shaped mixing plate is provided at the other end of each transverse mixing plate. A rotating upright is rotatably installed on each of the transverse mixing plates. A mixing strip is provided on the rotating upright. A transmission assembly is connected between the upper end of the rotating upright and the end cap. When the rotating upright rotates with the sleeve, it can be driven to rotate by the transmission assembly.
[0007] In some embodiments, a rectangular block is provided on the output shaft of the motor, and a square hole groove that mates with the rectangular block is provided at the lower end of the sleeve.
[0008] In some embodiments, an annular flange pressure block is provided at the inner end of the end cap, corresponding to the rotating upright. When the end cap is in the closed state, the annular flange pressure block is located above the rotating upright to restrict the rotating upright from moving upward.
[0009] In some embodiments, the transmission assembly includes a large gear located at the center of the inner end of the end cap, and a small gear meshing with the large gear is provided at the upper end of each of the rotating uprights.
[0010] In some embodiments, the end cap is detachably installed on the upper end of the mixing drum via several latches.
[0011] In some embodiments, a feed hopper is provided at the upper end of the end cap, and a first insert plate for closing or opening the feed hopper is movably inserted into the feed hopper.
[0012] In some embodiments, a discharge hopper is provided on one side of the lower end of the mixing drum, and a second insert plate for closing or opening the discharge hopper is movably inserted on the discharge hopper.
[0013] In some embodiments, a support frame for supporting the stirring tank is also included, and the motor is mounted on the support frame.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] 1. Through an innovatively designed mixing assembly, the coordinated movement of primary and auxiliary mixing is achieved. When the sleeve drives the transverse mixing plate in a circular motion, it can laterally push and stir the plastic granules in the bottom area of the mixing drum. The V-shaped mixing plate at the end of the transverse mixing plate, with its unique V-shaped structure, can both expand the mixing range and create a bidirectional, enveloping agitation of the granules near the inner wall of the mixing drum, effectively avoiding the problem of insufficient mixing of granules near the inner wall in traditional mixers. Simultaneously, the rotating upright, driven by the transmission assembly, rotates on its own axis while revolving with the sleeve. The stirring strips on its surface can longitudinally penetrate and disperse the granules at different heights within the mixing drum, achieving all-round, dead-angle-free mixing of plastic granules in a multi-dimensional space. This significantly improves mixing uniformity and ensures the stability of the quality of subsequent processed products.
[0016] 2. Compared with the traditional stirring structure with a single motion trajectory, the multi-dimensional motion of the stirring component in this patent significantly enhances the disturbance intensity and dispersion effect on plastic particles, enabling uniform mixing of particles in a shorter time. This not only reduces the energy consumption of the equipment but also greatly shortens the production cycle, improves overall production efficiency, and reduces production costs for enterprises.

[0020] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.
[0021] like Figures 1-3 The plastic granule mixing mixer shown includes a mixing drum 1 and an end cap 10 covering the upper end of the mixing drum 1. A motor 2 is provided at the bottom of the mixing drum 1. The output shaft of the motor 2 extends into the mixing drum 1 and is provided with a mixing assembly. The mixing assembly includes a sleeve 3 connected to the output shaft of the motor 2. Several transverse mixing plates 4 are evenly distributed and spaced along the circumference of the outer wall of the sleeve 3. A V-shaped mixing plate 5 is provided at the other end of the transverse mixing plate 4. A rotating rod 6 is rotatably installed on each of the transverse mixing plates 4. A mixing strip 7 is provided on the rotating rod 6. A transmission assembly is connected between the upper end of the rotating rod 6 and the end cap 10. When the rotating rod 6 rotates with the sleeve 3, it can be driven to rotate by the transmission assembly.
[0022] When the equipment is started, the motor 1 installed at the bottom of the mixing drum 1 begins to run. The output shaft of the motor 1 transmits power to the sleeve 3 extending into the inside of the mixing drum 1. Since the sleeve 3 is directly connected to the output shaft of the motor 2, the rotation of the motor 2 drives the sleeve 2 to rotate synchronously around its own axis. Several transverse stirring plates 4 are evenly distributed and spaced along the circumference of the outer wall of the drum 3. The rotation of the sleeve 3 directly drives all the transverse stirring plates 4 to perform horizontal circular motion around the sleeve 3 in the mixing drum 1. During the movement, the transverse stirring plates 4 generate a transverse thrust on the plastic particles in the bottom area of the mixing drum 1, pushing the particles to flow horizontally, initially achieving particle diffusion and mixing. At the same time, the V-shaped stirring plate 5 set at the other end of the transverse stirring plate 4 moves synchronously with the transverse stirring plate 4. The V-shaped structure of the V-shaped stirring plate 5 can agitate the plastic particles near the inner wall of the mixing drum 1, which not only expands the mixing coverage area, but also guides the particles that are easy to accumulate near the inner wall to the mixing center area, avoiding particles from being stuck on the drum wall. Each transverse stirring plate 4 is rotatably mounted with a rotating upright 6. The rotating upright 6 can rotate freely around its own axis, and its upper end is connected to the end cap 10, which is closed on the upper end of the stirring drum 1, through a transmission assembly. When the transverse stirring plate 4 moves in a circular motion with the sleeve 3, the rotating upright 6 will revolve synchronously around the axis of the sleeve 3 with the transverse stirring plate 4. During this process, the transmission assembly fixed on the end cap 10 will exert a constraint force on the rotating upright 6. Since one end of the transmission assembly is fixed and the other end is connected to the rotating upright 6, the revolution of the rotating upright 6 is converted into its own rotation around its axis through the force transmission and motion conversion of the transmission assembly. When the rotating rod 6 rotates, the stirring strips 7 on its surface rotate synchronously with the rotating rod 6. During the rotation, the stirring strips 7 longitudinally penetrate and stir the plastic particles at different heights in the mixing drum 1. At the same time, the revolution and rotation of the rotating rod 6 are coordinated. The stirring strips 7 not only make a circular motion around the sleeve 3 with the rotating rod 6, but also rotate on their own, forming a complex motion trajectory in three-dimensional space, further dispersing and turning the particles. Finally, in conjunction with the main stirring motion of the transverse stirring plate 4 and the V-shaped stirring plate 5, the plastic particles are mixed in an all-round and dead-angle-free manner in the mixing drum 1.
[0023] See Figure 2 , Figure 3 As shown, a rectangular block 21 is provided on the output shaft of the motor 2, and a square hole groove 22 that mates with the rectangular block 21 is provided at the lower end of the sleeve 3.
[0024] During equipment assembly, align the rectangular block 21 on the output shaft of motor 2 with the square hole groove 22 at the lower end of sleeve 3, so that the rectangular block 21 is completely embedded in the square hole groove 22. Since the rectangular block 21 and the square hole groove 22 are rigid structures with matching shapes, they can form a fixed fit without relative rotation after being embedded, realizing precise power connection between the output shaft of motor 2 and sleeve 3.
[0025] Compared to welding or complex multi-key connections, the rectangular block 21 and the square hole groove 22 adopt a plug-in mating structure. When the mixing component needs to be disassembled for equipment maintenance, simply open the end cover 10 and lift the sleeve 3 to separate the square hole groove 22 from the rectangular block 21 without the need for professional tools or cutting and disassembling bolts. During installation, simply align the shape for quick insertion and fixation. This design greatly reduces the difficulty and time cost of equipment maintenance, and is especially suitable for production scenarios that require frequent cleaning or replacement of mixing components.
[0026] Furthermore, an annular flange pressure block 31 corresponding to the rotating upright 6 is provided at the inner end of the end cover 10. When the end cover 10 is in the closed state, the annular flange pressure block 31 is located above the rotating upright 6 to restrict the rotating upright 6 from moving upward.
[0027] When the stirring assembly is installed inside the stirring drum 1, the end cap 10 is then closed, so that the pre-set annular flange pressure block 31 at the inner end of the end cap 10 is precisely aligned with each rotating rod 6; the annular flange pressure block 31 is located in the upper region of the rotating rod 6, and the lower surface of the annular flange pressure block 31 maintains a small gap with the upper end surface of the rotating rod 6 (the size of the gap is such that it does not affect the rotation of the rotating rod 6 and can limit its upward displacement), thus completing the assembly of the axial limiting structure of the rotating rod 6.
[0028] See Figure 2 , Figure 3 As shown, the transmission assembly includes a large gear 41 located at the center of the inner end of the end cover 10, and a small gear 42 that meshes with the large gear 41 is provided at the upper end of each of the rotating uprights 6.
[0029] During equipment assembly, the large gear 41 is first fixedly installed at the center of the inner end of the end cover 10, ensuring that the axis of the large gear 41 coincides with the axis of the stirring drum 1 (i.e., the output shaft of the motor 2 and the axis of the sleeve 3). Then, small gears 42 are installed on the upper end of each rotating rod 6, with the installation height of the small gears 42 precisely matched. When the end cover 10 is closed on the upper end of the stirring drum 1, the small gears 42 on each rotating rod 6 can form a tight mesh with the large gear 41 at the inner end of the end cover 10, while ensuring that the small gears 42 can rotate freely with the rotating rod 6, thus completing the assembly and positioning of the transmission components. When the equipment is started, the motor 2 drives the sleeve 3 to rotate, and the sleeve 3, through the transverse stirring plate 4, drives all the rotating rods 6 to revolve around the axis of the sleeve 3. Since the small gear 42 at the upper end of the rotating rod 6 is always meshed with the large gear 41 fixed on the end cover 10, and the large gear 41 is stationary, the revolution of the rotating rod 6 is converted into the rolling motion of the small gear 42 along the circumference of the tooth ring of the large gear 41. While the small gear 42 revolves around the center of the large gear 41, it will generate its own rotational motion due to the meshing force of the tooth surface of the large gear 41. The rotation of the small gear 42 directly drives the rotating rod 6, which is fixedly connected to it, to rotate synchronously. The stirring strips 7 on the surface of the rotating rod 6 generate longitudinal interlacing and stirring motions as the rod rotates.
[0030] In this utility model, the end cap 10 is detachably installed on the upper end of the mixing drum 1 by a number of latches 51.
[0031] During equipment assembly or maintenance, after the end cover 10 is placed on the upper end of the mixing drum 1, the end cover 10 can be detachably fixed by operating several latches 51 evenly distributed around the circumference of the edge of the end cover 10 and the mixing drum 1. The latches 51 usually adopt a snap-on structure, with one end fixedly connected to the outer wall of the mixing drum 1, and the other end rotating around the connection point. After the end cover is closed, the latches 51 are rotated so that their locking ends lock into the slots or protrusions on the edge of the end cover 10. The locking force of the latches tightly presses the end cover 10 onto the upper end of the mixing drum 1. When it is necessary to open the end cover, the latches 51 are rotated in the opposite direction to release the locking constraint, and the end cover 10 can be removed upwards to complete the disassembly of the end cover.
[0032] Furthermore, a feed hopper 61 is provided at the upper end of the end cap 10, and a first insert plate 62 for closing or opening the feed hopper 61 is also movably inserted on the feed hopper 61.
[0033] Before mixing the plastic granules, materials need to be added to the mixing drum 1. This is done through the feed hopper 61 at the top of the end cap 10. The feed hopper 61 is connected to the inside of the end cap 10. The plastic granules are poured into the feed hopper 61 from the top opening, and the granules slide down the inclined inner wall of the feed hopper into the mixing drum 1. The first insert plate 62 is usually a rectangular flat plate, which is inserted into the slot on the side wall of the feed hopper 61 and can slide laterally along the slot. When the first insert plate 62 is fully inserted, its plate can block the internal channel of the feed hopper 61, thereby sealing the feed hopper and preventing the granules from continuing to enter the mixing drum.
[0034] A discharge hopper 71 is provided on one side of the lower end of the mixing drum 1, and a second insert plate 72 for closing or opening the discharge hopper 71 is movably inserted on the discharge hopper 71.
[0035] During the mixing process of plastic granules, it is necessary to maintain a relatively closed environment inside the mixing drum 1. At this time, the discharge channel is closed by a second insert plate 72 that is movably inserted into the discharge hopper 71. The second insert plate 72 is usually a rectangular flat plate adapted to the channel of the discharge hopper 71, inserted into a slot in the side wall of the discharge hopper 71, and can slide laterally along the slot. Before mixing, the second insert plate 72 is fully inserted into the slot, and its plate can tightly cover the internal channel connecting the discharge hopper 71 and the mixing drum 1, preventing unevenly mixed granules from leaking out of the discharge hopper during the mixing process, and ensuring that the granules can be fully mixed by the mixing components in the mixing drum 1. Once the plastic granules have reached the preset mixing time and are uniformly mixed, the operator can control the discharge status by pulling the second insert plate 72. For rapid discharge, the second insert plate 72 can be completely pulled out, fully opening the channel of the discharge hopper 71. The mixed granules, under their own gravity, flow from the discharge port at the bottom of the mixing drum 1 into the discharge hopper 71, and then slide down the inclined inner wall of the discharge hopper to the external receiving device. To control the discharge speed or pause discharge, the insertion depth of the second insert plate 72 can be adjusted. When partially inserted, the plate partially blocks the discharge channel, reducing the amount of granules flowing out per unit time, achieving slow, quantitative discharge. If discharge needs to be paused midway, the second insert plate 72 can be fully inserted again to close the channel, flexibly adapting to different receiving requirements.
[0036] The present invention also includes a support frame 81 for supporting the stirring drum 1, and the motor 2 is mounted on the support frame 81.
