Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a particle mixing and extrusion device. Background Technology

[0002] In chemical, pharmaceutical, and food processing industries, it is often necessary to uniformly mix and extrude various granular raw materials to prepare granular products of specific shapes. In traditional processes, mixing and extrusion are usually completed in separate steps: first, the granules are mixed using equipment such as mixers or V-mixers, and then extrusion molding is performed using extruders or tablet presses. However, existing extrusion equipment suffers from the following problems:

[0003] 1. Cumbersome process and poor integration: Materials need to be transferred multiple times, resulting in low efficiency, high energy consumption, and easy to introduce pollution risks due to exposure to the environment;

[0004] 2. Uneven mixing: Conventional mixing devices are difficult to fully mix materials with large differences in particle density and size, and process parameters need to be repeatedly adjusted before extrusion.

[0005] To address this, we designed a particle mixing and extrusion device. Utility Model Content

[0006] This utility model discloses a particle mixing and extrusion device. To achieve the above-mentioned objective, this utility model adopts the following technical solution:

[0007] A particle mixing and extrusion device includes a base, and a mixing mechanism and an extrusion mechanism are disposed on the upper surface of the base;

[0008] The extrusion mechanism includes a receiving box, a vertical plate fixedly mounted on the upper surface of the receiving box, a drive motor mounted on the top of the vertical plate, a drive screw fixedly connected to the output shaft of the drive motor, a lifting plate threadedly connected to the surface of the drive screw, an extrusion cylinder fixedly mounted above the receiving box, a movable rod fixedly connected to the lower surface of the lifting plate, and the bottom end of the movable rod extending into the interior of the extrusion cylinder and fixedly connected to an extrusion disc.

[0009] The inner top wall of the receiving box is rotatably equipped with a linkage shaft, the bottom end of which is fixedly connected to a rotating head, and the surface of the rotating head is fixedly connected with several cutting blades. The bottom end of the extrusion cylinder is fixedly embedded with a discharge pipe, and the bottom end of the discharge pipe is threadedly connected to a discharge bottom cover. The surface of the discharge bottom cover is provided with several discharge holes.

[0010] In a preferred embodiment, the cutting blades correspond to the position of the discharge bottom cover, with the cutting blades located below the discharge bottom cover and the discharge bottom cover located above the receiving box.

[0011] In a preferred embodiment, the bottom end of the drive screw is rotatably connected to the upper surface of the receiving box, and a drive synchronous pulley is fixedly connected to the bottom of the drive screw. A driven synchronous pulley is fixedly connected to the top end of the linkage shaft, and a transmission belt is installed between the drive synchronous pulley and the driven synchronous pulley.

[0012] In a preferred embodiment, the size of the extrusion disc matches that of the extrusion cylinder, and the extrusion disc is slidably connected to the inner wall of the extrusion cylinder.

[0013] In a preferred embodiment, the mixing mechanism includes a mixing tank, a conveying pipe fixedly disposed at the bottom of the mixing tank, the end of the conveying pipe away from the mixing tank extending into the interior of the extrusion cylinder, and a switch valve fixedly disposed on the surface of the conveying pipe.

[0014] In a preferred embodiment, a stirring motor is fixedly mounted on the upper surface of the mixing tank, the output shaft of the stirring motor extends into the interior of the mixing tank, and a stirring rod is fixedly mounted thereon, with stirring blades fixedly connected to the surface of the stirring rod.

[0015] In a preferred embodiment, two feed square tubes are fixedly embedded on the upper surface of the mixing tank, and a support frame is fixedly installed at the bottom end of the mixing tank, with the bottom end of the support frame fixedly connected to the upper surface of the base.

[0017] Firstly, by setting up an extrusion mechanism and a mixing mechanism, the plastic granule raw material can be stirred and mixed first using the mixing mechanism. Then, the lifting plate drives the extrusion disc to move downward inside the extrusion cylinder, thereby extruding the raw material and sending it into the discharge pipe. The raw material is then discharged through several discharge holes on the surface of the discharge bottom cover at the bottom of the discharge pipe. Furthermore, while the drive motor drives the drive screw to rotate, the drive synchronous wheel drives the driven synchronous wheel and the linkage shaft to rotate, thereby driving several cutting blades to rotate below the discharge bottom cover. The rotating cutting blades cut the raw material. This integrated extrusion and cutting operation improves the efficiency of granule processing.

[0018] Secondly, by setting a collection box on the base surface and using the collection box to surround the bottom of the extrusion cylinder, the collection box can be used to collect the granular raw materials generated during the cutting process of the cutting blade, avoiding the granules from flying everywhere after cutting, thus making it convenient for workers to collect and discharge the cut plastic granules.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1 and Figure 2 A particle mixing and extrusion device includes a base 1, and a mixing mechanism 2 and an extrusion mechanism 3 are disposed on the upper surface of the base 1.

[0026] Reference Figure 3 and Figure 4 In a preferred embodiment, the extrusion mechanism 3 includes a receiving box 301, a vertical plate 302 is fixedly disposed on the upper surface of the receiving box 301, a drive motor 303 is disposed on the top of the vertical plate 302, a drive screw 304 is fixedly connected to the output shaft of the drive motor 303, a lifting plate 305 is threadedly connected to the surface of the drive screw 304, and an extrusion cylinder 306 is fixedly disposed above the receiving box 301.

[0027] The extrusion cylinder 306 can be used to extrude the mixed plastic raw materials, thereby forming the raw materials into granules of different shapes.

[0028] Reference Figure 3 and Figure 4In a preferred embodiment, the mixing mechanism 2 includes a mixing tank 201, a conveying pipe 202 is fixedly provided at the bottom of the mixing tank 201, one end of the conveying pipe 202 away from the mixing tank 201 extends into the interior of the extrusion cylinder 306, and a switch valve 203 is fixedly provided on the surface of the conveying pipe 202.

[0029] By opening the switch valve 203 on the surface of the conveying pipe 202, the mixed raw materials in the mixing tank 201 can be conveyed to the extrusion cylinder 306 through the conveying pipe 202.

[0030] A stirring motor 204 is fixedly installed on the upper surface of the mixing tank 201. The output shaft of the stirring motor 204 extends into the interior of the mixing tank 201 and is fixedly installed with a stirring rod 205. A stirring blade 206 is fixedly connected to the surface of the stirring rod 205. The stirring motor 204 can drive the stirring rod 205 to rotate, thereby driving the stirring blade 206 to stir and mix the raw materials.

[0031] It should be noted that two feed square tubes 207 are fixedly embedded on the upper surface of the mixing tank 201, and a support frame is fixedly installed at the bottom of the mixing tank 201. The bottom of the support frame is fixedly connected to the upper surface of the base 1.

[0032] A movable rod 307 is fixedly connected to the lower surface of the lifting plate 305. The bottom end of the movable rod 307 extends into the interior of the extrusion cylinder 306 and is fixedly connected to an extrusion disc 308. The size of the extrusion disc 308 matches that of the extrusion cylinder 306, and the extrusion disc 308 is slidably connected to the inner wall of the extrusion cylinder 306. Under the action of the movable rod 307, the extrusion disc 308 is driven to move up and down inside the extrusion cylinder 306, which can extrude the raw material.

[0033] It should be noted that a linkage shaft 309 is rotatably installed on the inner top wall of the receiving box 301. The bottom end of the drive screw 304 is rotatably connected to the upper surface of the receiving box 301. A drive synchronous wheel 315 is fixedly connected to the bottom of the drive screw 304, and a driven synchronous wheel 316 is fixedly connected to the top of the linkage shaft 309. A transmission belt 317 is installed between the drive synchronous wheel 315 and the driven synchronous wheel 316. It should be noted that the diameter of the drive synchronous wheel 315 is much larger than that of the driven synchronous wheel 316. Therefore, the driven synchronous wheel 316 can be accelerated under the drive of the drive synchronous wheel 315, thereby driving the cutting blade 311 to rotate at high speed, which is convenient for granular cutting of raw materials.

[0034] A rotating head 310 is fixedly connected to the bottom end of the linkage shaft 309. Several cutting blades 311 are fixedly connected to the surface of the rotating head 310. A discharge pipe 312 is fixedly embedded at the bottom end of the extrusion cylinder 306. A discharge bottom cover 313 is threadedly connected to the bottom end of the discharge pipe 312. Several discharge holes 314 are opened on the surface of the discharge bottom cover 313. The discharge bottom cover 313 can be replaced, making it convenient to replace the discharge bottom cover 313 with different sizes and specifications of discharge holes 314 according to the size of the plastic particles.

[0035] It is worth noting that by setting a receiving box 301 on the surface of the base 1 and using the receiving box 301 to surround the bottom of the extrusion cylinder 306, the receiving box 301 can be used to collect the granular raw materials generated during the cutting process of the cutting blade 311, avoiding the granules from splashing everywhere after cutting, thus making it convenient for workers to discharge the cut plastic granules in a concentrated manner.

[0036] It should be noted that the position of the discharge bottom cover 313 corresponds to that of the cutting blade 311. The cutting blade 311 is located below the discharge bottom cover 313, and the discharge bottom cover 313 is located above the receiving box 301.

[0037] It is worth noting that by setting up the extrusion mechanism 3 and the mixing mechanism 2, the plastic granule raw material can be stirred and mixed first using the mixing mechanism 2. Then, the drive motor 303 drives the lifting plate 305 to move downward, thereby driving the extrusion disc 308 to move downward inside the extrusion cylinder 306. The extrusion disc 308 then extrudes the raw material, which enters the discharge pipe 312. The raw material is then discharged through several discharge holes 314 on the surface of the discharge bottom cover 313 at the bottom of the discharge pipe 312. At the same time, the drive motor 303 drives the drive screw 304 to rotate, and the drive synchronous wheel 315 drives the driven synchronous wheel 316 and the linkage shaft 309 to rotate, thereby driving several cutting blades 311 to rotate below the discharge bottom cover 313. The rotating cutting blades 311 cut the raw material. The integrated operation of extrusion and cutting improves the efficiency of granule processing.

[0038] Working principle: In use, different colored plastic raw materials are first fed into the mixing tank 201 through the feed square tube 207. Then, the stirring motor 204 is started, driving the stirring rod 205 to rotate. The stirring rod 205 drives the stirring blade 206 to rotate, using the stirring blade 206 to stir and mix the raw materials. Then, the mixed raw materials are fed into the extrusion cylinder 306 through the conveying pipe 202. Next, the drive motor 303 drives the drive screw 304 to rotate, which in turn drives the lifting plate 305 to move downward. The lifting plate 305 drives the movable rod 307 to move, thereby driving the extrusion disc 308 to extrude the raw materials downward inside the extrusion cylinder 306. The raw material enters the discharge pipe 312 and is discharged through the discharge hole 314 on the surface of the discharge bottom cover 313, forming a long strip shape corresponding to the shape of the discharge hole 314. At the same time, when the drive screw 304 rotates, it can drive the drive synchronous wheel 315 to rotate. The drive synchronous wheel 315 drives the driven synchronous wheel 316 to rotate through the transmission belt 317, which in turn drives the linkage shaft 309 to rotate. The linkage shaft 309 drives several cutting blades 311 to cut the extruded raw material, turning the raw material into granules. The granules are collected by the collection box 301, making it convenient for the staff to discharge the cut granules.

[0039] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
