Description

Technical Field

[0001] This disclosure relates to the field of plastic mixing and feeding technology, and in particular to a volumetric multi-material mixer. Background Technology

[0002] When processing plastic granules, it is necessary to mix plastic granules of different colors and sizes before feeding them into downstream equipment for processing. Existing plastic granule mixing and feeding devices generally feed materials from the top via a screw, and then mix them with a stirring rod at the bottom before feeding them out. However, when multiple materials are fed at the same time, the plastic granules fall very quickly due to gravity, and the stirring rod does not mix them sufficiently, resulting in uneven mixing of the plastic granules.

The hopper fixing block is fixedly connected to the side of the mixing base. The bearing fixing seat includes an integrally formed connecting seat and a connecting pipe. The connecting seat is disposed on the side of the hopper fixing block, and the connecting pipe is embedded inside the hopper fixing block. The hopper seat is fixedly connected to the side of the connecting seat away from the hopper fixing block. The hopper is fixedly connected to the top of the hopper seat and is connected through the hopper seat. The feeding motor is fixedly connected to the side of the hopper seat. The output shaft of the feeding motor is drivenly connected to the feeding screw. The feeding screw passes through the hopper seat, the bearing fixing seat, and the hopper fixing block and extends into the mixing base.

[0027] Example

[0028] like Figure 1-5 As shown, this embodiment provides a volumetric multi-material mixer, including a mixing base 1. The bottom of the mixing base 1 has a discharge port 101. Plastic granules, after being mixed, are discharged from the discharge port 101. A mixing mechanism is arranged above the discharge port 101 on the mixing base 1. Several feeding mechanisms 3 are arranged at the top of the mixing base 1. In this embodiment, there are four feeding mechanisms 3, which are respectively arranged on the four sides of the mixing base 1. A first funnel 4 is welded or bolted to the upper part of the mixing base 1. A guide pipe 5 is detachably connected to the bottom of the first funnel 4. A cleaning door 7 is hinged to the side of the mixing base 1. The feeding mechanisms 3 feed different plastic granules into the first funnel 4. After initial mixing in the first funnel 4, the granules enter the guide pipe 5 from the outlet of the first funnel 4. The granules are then guided by the guide pipe 5 onto the mixing mechanism for further mixing, and finally discharged from the discharge port 101 to downstream equipment for processing.

[0029] Specifically, the bottom of the first funnel 4 is integrally formed with a discharge port 101, and a locking block 402 is fixedly connected to the side of the discharge port 401. A "J"-shaped locking slot 501 is opened at the top of the guide pipe 5 at the position corresponding to the locking block 402, and the locking slot 501 is locked on the locking block 402. When installing the guide tube 5, it is inserted into the clamp 402 through the bayonet 501, and then the guide tube 5 is suspended and fixed by the clamp 402. Similarly, when disassembling, simply lift the guide tube 5 and remove it from the clamp 402. If it is necessary to change to different plastic granules for mixing and feeding, since the different plastic granules have different specifications and feeding speeds, it is necessary to open the cleaning door 7, remove the guide tube 5, place a receiving basin under the first funnel 4, start the feeding mechanism 3 to feed, record the feeding time, then stop feeding, take out the receiving basin and weigh it to calculate the relationship between feeding speed and weight. The total feeding amount can be controlled by adjusting the feeding speed of the feeding mechanism 3. It only needs to be tested once each time a different plastic granule is changed.

[0030] Furthermore, a second funnel 6 is welded or bolted to the bottom of the stirring base 1, and the bottom end of the guide tube 5 is embedded in the bottom opening of the second funnel 6. The second funnel 6 limits the bottom of the guide tube 5, preventing it from shaking and falling off during operation.

[0031] Specifically, the stirring mechanism includes a stirring motor 21 and a stirring rod 22. The stirring motor 21 is fixedly connected to the side of the stirring base 1, and the output shaft of the stirring motor 21 is connected to the stirring rod 22. The stirring rod 22 passes through the stirring base 1 and extends to the inner side of the stirring base 1. The stirring motor 21 drives the stirring rod 22 to rotate. When the plastic granules fall, they pass through the stirring rod 22, are mixed by the stirring rod 22, and are then discharged from the discharge port 101 into downstream equipment for processing.

[0032] Specifically, the feeding mechanism 3 includes a hopper 34, a hopper base 33, a hopper fixing block 31, a bearing fixing seat 32, a feeding motor 35, a feeding screw 36, and a feeding sleeve 37. The hopper fixing block 31 is fixedly connected to the side of the mixing base 1 by bolts. The bearing fixing seat 32 includes an integrally formed connecting seat 321 and a connecting pipe 322. The connecting seat 321 is disposed on the side of the hopper fixing block 31 for fixing to the hopper base 33. The connecting pipe 322 is embedded inside the hopper fixing block 31. The hopper fixing block 31 and the connecting pipe 322 are fixed by fixing screws 311. The hopper seat 33 is bolted to the side of the connecting seat 321 away from the hopper fixing block 31. The hopper 34 is fixedly connected to the top of the hopper seat 33 and is connected through the hopper seat 33. The feeding motor 35 is bolted to the side of the hopper seat 33. The output shaft of the feeding motor 35 is connected to the feeding screw 36. The feeding screw 36 passes through the hopper seat 33, the bearing fixing seat 32, and the hopper fixing block 31 and extends into the interior of the mixing base 1. The feeding sleeve 37 is sleeved on the outside of the feeding screw 36 and is fixedly connected to the bearing seat. Plastic granules are loaded into the hopper 34 and enter the hopper seat 33 by gravity. The feeding motor 35 drives the feeding screw 36 to rotate, and the plastic granules are driven by the feeding screw 36 into the feeding sleeve 37, and finally enter the top of the mixing base 1 and fall into the first funnel 4. By unscrewing the fixing screw 311, the feeding mechanism 3 can be disassembled and detached from the hopper fixing block 31 for easy replacement.

[0033] Furthermore, a pull plate fixing frame 38 is fixedly connected to the bottom of the hopper seat 33, and a pull plate 39 is movably connected to the bottom of the pull plate fixing frame 38. A discharge port is provided at the bottom of the hopper seat 33, and the pull plate 39 is movably and closable at the bottom of the discharge port. The discharge port at the bottom of the hopper seat 33 is used to discharge remaining material. Generally, when changing the plastic granule raw material, the pull plate 39 is pulled open to open the discharge port, allowing the remaining plastic granules to fall out. After the discharge is cleaned, the pull plate 39 is used to seal the discharge port again, and plastic granules can be added again.

[0034] Furthermore, a positioning block 391 is bolted to the surface of the pull plate 39. Positioning beads 392 are embedded at both ends of the positioning block 391. Positioning holes 381 are provided on both sides of the pull plate fixing bracket 38, and the positioning beads 392 can be embedded in the positioning holes 381. When the pull plate 39 is in the closed discharge port state, the positioning beads 392 are embedded in the positioning holes 381. Pulling the pull plate 39 disengages the positioning beads 392 from the positioning holes 381, opening the discharge port, and then re-closing the discharge port, push the pull plate 39 in the opposite direction to re-embed the positioning beads 392 into the positioning holes 381, thereby positioning the pull plate 39 and ensuring that the discharge port is closed.

[0035] The hopper 34 has a first viewing window 81 on its side, and the bottom of the mixing bottom has a second viewing window 82. The first viewing window 81 allows observation of the remaining plastic particles inside the hopper 34, while the second viewing window 82 allows observation of the mixing of the plastic particles by the bottom mixing mechanism.

[0036] In one embodiment, an electrical control box 9 is further included. The electrical control box 9 is fixedly connected to the side of the stirring base 1, and is electrically connected to both the stirring mechanism and the feeding mechanism 3. The electrical control box 9 contains a PLC controller and a power supply, which are used to control the operation of the stirring mechanism and the feeding mechanism 3 and to provide them with power.

[0037] The working principle of this invention is as follows: Plastic granules to be mixed and fed are placed in different feeding mechanisms 3. The feeding motor 35 drives the feeding screw 36 to rotate, which in turn drives the plastic granules into the mixing base 1. After converging through the first funnel 4, the granules fall into the mixing mechanism through the guide pipe 5. After being mixed, the granules are discharged from the discharge port 101 and enter downstream equipment for processing.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit them. Although this disclosure has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this disclosure.
