Description

Technical Field

[0001] The invention relates to the technical field of extrusion devices, and in particular to an extrusion device for producing filled particles. Background Art

[0002] In the process of filling particle production, raw material resin and filler are often added into the extruder for melt extrusion. The main steps include: raw material pretreatment: drying, screening and other pretreatment of plastic raw materials and fillers to ensure the quality and dryness of the raw materials; heating and melting: adding the pretreated raw materials into the extruder, and melting and mixing the raw materials evenly through heating and screw rotation; extrusion molding: extruding the molten plastic through the extruder head into continuous plastic strips; cooling and solidification: cooling the extruded plastic strips through a cooling water trough or air cooling to solidify them into hard plastic strips; cutting and granulation: cutting the solidified plastic strips into granular plastic particles of a certain length with a cutting tool. At present, when heating and melting raw material resin and filler, the extruder often relies on the heating plate embedded in the inner wall of the barrel for heating. Therefore, during the extrusion process, the raw material resin and filler flowing away from the inner wall of the barrel often cannot achieve a good heating and melting effect. If the internal temperature of the barrel is increased, it is easy for the temperature to be too high, causing part of the filler to carbonize and form black spots. If the temperature is not changed, the melting quality of the raw material resin and filler will be poor.

[0003] For this purpose, we propose an extrusion device for the production of filled granules. Summary of the invention

[0007] Preferably, the rotating rod passes through the through hole, the guide rod is slidably connected to the spiral groove, and the transmission gear is meshingly connected to the annular rack.

[0008] Preferably, the side walls of the circular blocks are symmetrically embedded with protective covers in sliding connection, and one end of each protective cover away from the circular blocks is fixedly connected to an adjacent side wall of the horizontal plate.

[0009] Preferably, a micro motor is fixedly connected to the inner wall of the annular cavity, a driving shaft is fixedly connected to the output end of the micro motor, a first gear is fixedly connected to the side wall of the driving shaft, a second gear is fixedly connected to the side wall of one of the rotating shafts, and the first gear and the second gear are meshingly connected.

[0010] Preferably, a slide groove is provided on the inner wall of the rough material barrel, a lead screw is rotatably connected to the side wall of the slide groove, a slider is threadedly connected to the side wall of the lead screw, and the annular plate and the side wall of the slider are embedded in a sliding connection.

[0011] Preferably, a protection strip is symmetrically fixedly connected to the side wall of the slide block, and the other end of the protection strip away from the slide block is embedded and fixed to the inner side wall of the slide groove.

[0012] Preferably, a first screw assembly and a second screw assembly are respectively provided inside the fine material barrel, one end of each of the fine material barrels is fixedly connected to a transmission device, the first screw assembly is fixedly connected to an adjacent transmission device, and the second screw assembly is fixedly connected to an adjacent transmission device.

[0013] Preferably, the side wall of the coarse material barrel is fixedly connected to a drive motor, the output end of the drive motor is coaxially fixedly connected to the lead screw, one of the inner walls of the fine material barrel is penetrated and fixedly connected to a feed pipe, and the other inner wall of the fine material barrel is penetrated and fixedly connected to a discharge pipe.

[0014] Preferably, the L-shaped tube and the discharge tube are both one-way tubes, the length of the L-shaped tube provided on the side wall of each box body is different, and the internal capacity of each box body is also different.

[0015] Compared with the prior art, the present invention has the following advantages: 1. When the raw material resin and filler enter the rough material barrel, turn on the micro motor, and by setting up structures such as annular racks, driving gears and fan-shaped plates, each rotating shaft drives the fan-shaped plates symmetrically fixedly connected to its side walls to rotate synchronously, and the raw material resin and filler entering the rough material barrel are heated again to make them fully melted. Then, the fan-shaped plates fixed to the side walls of the rotating shafts evenly distributed along the circumferential array will cover and stir the cross-section inside the rough material barrel, thereby improving the heating and melting efficiency of the raw material resin and filler; 2. By setting up structures such as a driving motor, a guide rod and a round block, the driving motor is turned on, so that the round block will drive the circular plate to rotate synchronously with the round block as the center through multiple rotating shafts, and then the multiple rotating shafts provided on the circular plate will also rotate synchronously, and then the rotating shaft can also rotate with the round block as the center in the process of driving the fan-shaped plate to stir with the rotating shaft as the center, thereby increasing the stirring range of the two fan-shaped plates driven by the rotating shaft, thereby improving the heating and melting quality of the raw material resin and filler; 3. During the rotation of each shaft, the shaft will also drive the circular plate fixed to it to rotate. By setting the box body, slide plate and push rod and other structures, the melting temperature sensor embedded in the inner wall of the box body can detect the melting degree of the raw material resin and filler that are heated and melted; 4. When this part of the heated and molten raw material resin and filler meets the standards after testing, the user controls the micro motor to rotate the multiple shafts at a certain angle until the multiple fan-shaped plates are in the same vertical plane. Then, the drive motor is turned on to move the slider to the left. Then, the multiple fan-shaped plates in the same vertical plane will transport the molten raw material resin and filler in this area to the left inside the fine material barrel fixed with the discharge pipe, and then extrude them through the second screw assembly to avoid the molten raw material resin and filler staying in the coarse material barrel for a long time to be heated and melted, resulting in carbonization caused by high temperature; 5. Since the length of the L-shaped tube set on the side wall of each box body is different and the internal capacity of each box body is also different, when the slide plate slides back and forth in the corresponding box body, the molten raw material resin and filler at different positions inside the rough material barrel can be drawn into the L-shaped tubes of different lengths, thereby improving the detection accuracy of the heated and molten raw material resin and filler.

A slider 7 is threadedly connected to the side wall of the lead screw 6. The circular ring plate 8 and the side wall of the slider 7 are embedded in a sliding connection. The circular ring plate 8 can slide on the side wall of the slider 7 to form a rotating effect, and the circular ring plate 8 and the inner wall of the rough material barrel 2 slide against each other.

[0025] The side wall of the slider 7 is symmetrically fixedly connected with a protection strip 33, and the other end of the protection strip 33 away from the slider 7 is embedded and fixed with the inner wall of the slide groove 5, and the protection strip 33 is made of a telescopic high temperature resistant material.

[0026] A first screw assembly and a second screw assembly (not shown in the figure) are respectively provided inside the fine material barrel 3. One end of the fine material barrel 3 is fixedly connected to a transmission device 34. The transmission device 34 is of prior art. The first screw assembly is fixedly connected to the adjacent transmission device 34, and the second screw assembly is fixedly connected to the adjacent transmission device 34.

[0027] A driving motor 4 is fixedly connected to the side wall of the coarse material barrel 2, and the output end of the driving motor 4 is coaxially fixedly connected to the lead screw 6. A feed pipe 14 is fixedly connected to the inner wall of one of the fine material barrels 3, and a discharge pipe 16 is fixedly connected to the inner wall of the other fine material barrel 3.

[0028] The L-shaped tube 32 and the discharge tube 39 are both one-way tubes. The L-shaped tube 32 only allows the molten raw material resin and filler inside the coarse material barrel 2 to enter the box body 28, and the discharge tube 39 only allows the molten raw material resin and filler in the box body 28 to be discharged. The length of the L-shaped tube 32 set on the side wall of each box body 28 is different, and the internal capacity of each box body 28 is also different.

[0029] In the present invention, the user adds the raw material resin and filler into one of the fine material barrels 3 through the feed pipe 14, and then turns on the transmission device 34 corresponding to the fine material barrel 3. The transmission device 34 drives the first screw assembly fixedly connected thereto to rotate, and then the first screw assembly rotates inside the fine material barrel 3 to extrude and convey the raw material resin and filler until this part of the raw material resin and filler enters the coarse material barrel 2. The fine material barrel 3 is a prior art, and it has a heater inside. At this time, through the preheating and heating of the fine material barrel 3, part of the raw material resin and filler have been heated to a molten state.

[0030] In order to improve the melting effect of the raw material resin and filler, and avoid the low temperature causing the raw material resin and filler to not be completely melted, and the high temperature causing part of the filler to carbonize and form black impurities, the micro motor 40 is turned on at this time, and the micro motor 40 drives the driving shaft 38 fixedly connected to it to rotate, and the driving shaft 38 drives the first gear 18 fixedly connected to its side wall to rotate, so that the first gear 18 drives the second gear 19 meshing with it to rotate. Here, by setting the transmission ratio of the first gear 18 and the second gear 19, the second gear 19 drives the rotating shaft 10 fixedly connected to it to obtain a larger torque, then the rotating shaft 10 drives the annular rack 9 to slide on the inner wall of the annular cavity 36 through the transmission gear 11 fixedly connected to its side wall to produce a rotation effect, then the annular rack 9 will It will drive the other multiple transmission gears 11 meshing with it to rotate synchronously, and then the multiple transmission gears 11 will synchronously drive the rotating shaft 10 fixedly connected to it to rotate, so that the fan-shaped plates 12 symmetrically fixedly connected to the side walls of the rotating shaft 10 rotate synchronously. Since the inner walls of these fan-shaped plates 12 are embedded with heating resistor plates, these heating resistor plates generate heat after being started by the controller, thereby reheating the raw material resin and filler entering the rough material barrel 2 to fully melt them. Since each rotating shaft 10 drives the two fan-shaped plates 12 fixedly connected to it to rotate, the fan-shaped plates 12 fixed on the side walls of the multiple rotating shafts 10 evenly distributed along the circumferential array will cover and stir the cross-sectional part inside the rough material barrel 2, thereby improving the heating and melting efficiency of the raw material resin and filler.

[0031] At this time, the drive motor 4 is turned on. The drive motor 4 is a forward and reverse motor. The output end of the drive motor 4 drives the lead screw 6 fixedly connected to it to rotate, and the slider 7 threadedly connected to the side wall of the lead screw 6 will drive the circular ring plate 8 embedded and sliding with it to move synchronously in the horizontal direction. Since the inner wall of the through hole 22 opened on the inner wall of the circular block 13 is fixed with a guide rod 23, and the guide rod 23 and the spiral groove 21 opened on the side wall of the rotating rod 20 are inserted and slid, then in the process of the movement of the circular ring plate 8, under the action of the guide rod 23 and the spiral groove 21, the circular block 13 will drive the circular ring plate 8 to rotate synchronously with the circular block 13 as the center through the multiple rotating shafts 10, then the multiple rotating shafts 10 provided on the circular ring plate 8 will also rotate synchronously, and then the rotating shaft 10 drives the fan-shaped plate 12 to stir with the rotating shaft 10 as the center. The rotating shaft 10 can also rotate with the circular block 13 as the center, thereby increasing the range of stirring of the two fan-shaped plates 12 driven by the rotating shaft 10, thereby improving the heating and melting quality of the raw material resin and filler.

[0032] During the rotation of each shaft 10, the shaft 10 will also drive the circular plate 26 fixedly connected thereto to rotate, and the circular plate 26 will drive the cylinder 27 eccentrically fixedly connected to its side wall to rotate, then the cylinder 27 will drive the push rod 30 rotatably connected thereto to move, and the push rod 30 will drive the slide plate 29 rotatably connected to the other end thereof to slide back and forth in a sealed manner inside the corresponding box body 28, then the slide plate 29 will pass through the L-shaped tube 32 fixedly connected to the side wall of the box body 28 to stir the inside of the rough material barrel 2, and the heated and molten raw material resin and filler will be drawn into the box body 28, and the raw material resin and filler will be heated and molten by the L-shaped tube 32 embedded in the inner wall of the box body 28. The installed melting temperature sensor 31 detects the melting degree of this part of the heated and molten raw material resin and filler. When this part of the heated and molten raw material resin and filler meets the standard after detection (that is, the data detected by the melting temperature sensor 31 on the inner wall of each box body 28 meets the standard), the user controls the micro motor 40 to rotate the multiple shafts 10 by a certain angle until the multiple fan-shaped plates 12 are in the same vertical plane. Then, the drive motor 4 is turned on at this time, and the output end of the drive motor 4 drives the lead screw 6 to rotate, so that the slider 7 moves leftward inside the rough material barrel 2 (such as Figure 2 As shown), that is, it moves in the direction close to the discharge pipe 16, then the multiple fan-shaped plates 12 in the same vertical plane will transport the molten raw material resin and filler in this area to the left to the inside of the fine material barrel 3 fixed with the discharge pipe 16, and then extrude them through the second screw assembly, so as to avoid the molten raw material resin and filler staying in the coarse material barrel 2 for a long time to be heated and melted, resulting in carbonization caused by high temperature.

[0033] Since the length of the L-shaped tube 32 arranged on the side wall of each box body 28 is different and the internal capacity of each box body 28 is also different, when the slide plate 29 slides back and forth in a sealed manner inside the corresponding box body 28, the molten raw material resin and filler at different positions inside the coarse material barrel 2 can be drawn into the coarse material barrel 2 through the L-shaped tube 32 of different lengths, thereby improving the detection accuracy of the heated molten raw material resin and filler.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
