[0019] By adopting the above technical scheme, the vibration effect on the material is achieved, and the release speed of the gas in the material is further accelerated.

[0020] To sum up, the present application mainly has the following beneficial effects:

[0021] 1、The present application is provided with barrel assembly, stirring assembly and guide assembly, firstly, the material in molten state and the ingredients needed to be mixed are added into the stirring cavity through the first and second feeding ports, then the driving motor is started, the driving motor drives the first telescopic shaft to rotate, the first telescopic shaft in turn drives the second telescopic shaft to rotate, the second telescopic shaft in turn drives the horizontal plate on its outer wall to rotate, the horizontal plate in turn drives the stirring rod inside it to rotate, the stirring rod in turn drives the stirring blade to rotate, realizing the stirring and mixing effect of the material, and in the stirring process, the gas in the material is discharged, further, since the stirring blade and the stirring rod are obliquely arranged, the resistance of the stirring blade to the material will be smaller, achieving the energy-saving effect of the driving motor, at the same time, in the process of the stirring rod rotating, its top end will move in the auxiliary groove on the end face of the guide plate, when the stirring rod moves into the guide groove, the stirring rod will be transversely displaced under the guidance of the guide groove, at the same time, the movement groove of the horizontal plate will also assist the transverse movement of the stirring rod, then the stirring rod will produce oblique movement, in turn, the stirring blade will be inserted into the material at an oblique angle and then stirred, effectively improving the stirring quality, and the two groups of stirring blades arranged in parallel and opposite directions will produce relative movement, the material located between them will be subjected to the rubbing effect of the two groups of stirring blades, achieving the crushing effect of the ingredient particles, in turn, improving the mixing quality of the material, in addition, the two groups of stirring blades in the above-mentioned reciprocating movement process can also improve the gap between the materials, in turn, being conducive to the discharge of gas in the material, thereby being able to improve the extrusion quality of the extruder to a certain extent;

[0022] 2. This invention, by setting up a vibration component, a negative pressure component, and a purification component, allows the inner wall groove of the second telescopic shaft to guide the guide rod as it rotates. This means the guide rod moves up and down reciprocally under the action of the rotating groove, thus driving the vibrating block to move up and down reciprocally. When the vibrating block reaches the bottom of the telescopic shaft, it vibrates under the impact force. Correspondingly, the base plate on one side of the vibrating block is also affected by the vibration, and consequently, the material on the base plate is also affected. At this time, the gas in the material is accelerated out under the action of vibration, thereby achieving the effect of improving gas discharge. Simultaneously, the rotation of the second telescopic shaft drives the drive shaft to rotate, which in turn drives the fan blades to rotate. The rotating fan blades can... The system generates negative pressure, allowing gas in the mixing chamber to enter the negative pressure chamber through the air inlet and exit into the purification chamber through the air outlet. Once the gas enters the purification chamber, the activated carbon inside adsorbs and removes harmful substances, thus purifying the gas. Furthermore, the stirring rods inside the purification chamber agitate the activated carbon. Since the stirring rods can move up and down, the activated carbon can be randomly repositioned in all directions, effectively preventing some activated carbon from being fully loaded while others are empty. This ensures the adsorption quality of the activated carbon and improves the quality of gas purification. In addition, the purified gas flows back into the cavity through the return pipe, providing insulation for the mixing chamber and further improving the mixing quality of the materials.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of the present invention will now be described.

[0036] Please see Figures 1-2 The top of the machine body 101 is equipped with a material cylinder assembly 2. The material cylinder assembly 2 is divided into a mixing chamber 202 and a feeding chamber 203, which can realize the loading and feeding of materials. In addition, through the cavity design, the mixing chamber 202 can also be kept warm.

[0037] Specifically, the barrel assembly 2 includes a barrel body 201 installed above the feed inlet of the machine body 101, and the bottom end of the barrel body 201 is provided with a discharge port 204 communicating with the feed inlet. The interior of the barrel body 201 is composed of a stirring chamber 202 and a feeding chamber 203. The inner wall of the barrel body 201 is provided with a cavity 205, and the interior of the cavity 205 is connected to a return pipe 907 extending to the outside.

[0038] Please see Figures 2-5 The mixing assembly 3 is installed inside the material cylinder body 201. The mixing assembly 3 can play a mixing role for the material, and the mixing blade 306 can reduce the resistance it receives by being set at an angle, thereby achieving the energy-saving effect of the drive motor 301.

[0039] Specifically, the stirring assembly 3 includes a drive motor 301 installed above the top of the barrel body 201, and the output end of the drive motor 301 is connected to a first telescopic shaft 302. The bottom end of the first telescopic shaft 302 is connected to a second telescopic shaft 303. Both sides of the outer wall of the second telescopic shaft 303 are fixedly connected to a horizontal plate 304 inside the barrel body 201. A stirring rod 305 is installed inside the horizontal plate 304, penetrating the horizontal plate 304 and extending to the upper and lower ends of the horizontal plate 304. A stirring blade 306 is fixed to the outer wall of the stirring rod 305. The two sets of stirring blades 306 are arranged obliquely parallel to each other, and the horizontal angle between the stirring blades 306 and the stirring rod 305 is 30 degrees.

[0040] Please see Figures 2-4 Inside the barrel body 201, guide components 4 are provided on both sides of the mixing component 3. The guide components 4 can guide the mixing rod 305, so that the mixing rod 305 can also move laterally during rotation. This not only improves the mixing effect, but also allows the gas in the material to be released, thus improving the output quality of the extruder.

[0041] Specifically, the guide assembly 4 includes a guide plate 401 fixed to the inner wall of the barrel body 201 and slidably sleeved on the outer wall of the second telescopic shaft 303. The end face of the guide plate 401 is provided with an auxiliary groove 402 whose inner wall fits with the stirring rod 305. There are multiple sets of auxiliary grooves 402 distributed in a ring on the end face of the guide plate 401. Each pair of auxiliary grooves 402 is connected by a guide groove 403 whose inner wall fits with the stirring rod 305. The guide groove 403 is recessed inward. The end face of the horizontal plate 304 is provided with a moving groove 404. The inner wall of the moving groove 404 fits with the outer wall of the stirring rod 305. The stirring rod 305 is slidably connected laterally and vertically limited in the inner wall of the moving groove 404. The moving groove 404 is inclined on the end face of the horizontal plate 304. The inclination angle of the moving groove 404 is the same as the inclination angle of the stirring blade 306.

[0042] Please see Figure 2The material cylinder body 201 has a first feed port 5 and a second feed port 6 connected to both sides. The design of the two sets of feed ports can realize simultaneous feeding, thereby improving the feeding speed. In addition, it can also separate the auxiliary materials and the main materials to prevent contamination between materials.

[0043] Please see Figure 2 , Figure 6 and Figure 7 A vibration component 7 is installed at the separation point between the mixing chamber 202 and the feeding chamber 203. The vibration component 7 can vibrate the material, thereby accelerating the release of gas in the material.

[0044] Specifically, the vibration assembly 7 includes a vibration block 701 disposed below the bottom end of the second telescopic shaft 303, and both sides of the vibration block 701 are fixedly connected to a base plate 702 extending to the inner wall of the barrel body 201. The base plate 702 is laterally limited and vertically slidably connected to the inner wall of the barrel body 201, and an electric control door 703 is installed on the end face of the base plate 702. The top end of the vibration block 701 is fixedly connected to a connecting block 704 extending into the interior of the second telescopic shaft 303, and the outer side of the connecting block 704 is provided with a moving cavity 705 inside the second telescopic shaft 303. The outer wall of the connecting block 704 is fixedly connected to a guide rod 706 extending into the inner wall of the moving cavity 705, and the outer side of the guide rod 706 is provided with a sliding groove 708 adapted to the guide rod 706 on the inner wall of the moving cavity 705. The top end of the connecting block 704 is fixedly connected to an upwardly extending top rod 707.

[0045] Please see Figure 8 The inner top of the material cylinder body 201 is equipped with a negative pressure component 8. The negative pressure component 8 can generate negative pressure to draw in the gas released from the material in the mixing chamber 202, thereby achieving the function of collecting harmful waste gas.

[0046] Specifically, the negative pressure assembly 8 includes a negative pressure box 801 fixed to the top of the guide plate 401, and an air inlet 802 located inside the guide plate 401 is opened at the bottom of the negative pressure box 801. A fan blade 803 is installed inside the negative pressure box 801, and a drive shaft 804 extending to the top wall of the negative pressure box 801 and rotatably connected to it through a bearing is fixedly connected to the top of the fan blade 803. The drive shaft 804 is connected to the second telescopic shaft 303 through a transmission turntable and a transmission belt. An air outlet pipe 805 is connected to the top of the negative pressure box 801, and a one-way valve with an outward opening is installed inside the air outlet pipe 805.

[0047] Please see Figure 9 The top of the material cylinder body 201 is equipped with a purification component 9. The purification component 9 can render the harmful gases emitted by the material harmless. It can not only filter out the harmful components, but also flush the filtered gas into the cavity 205 to achieve the heat preservation effect of the mixing chamber 202.

[0048] Specifically, the purification component 9 includes a purification box 901 fixed to the top of the barrel body 201, and a turntable 902 is installed inside the purification box 901. Multiple sets of stirring rollers 903 are fixedly connected to one end face of the turntable 902, and a connecting shaft 904 extending to the outside of the purification box 901 is fixedly connected to the other end face of the turntable 902. A first bevel gear 905 is fixedly connected to the end of the connecting shaft 904, and an auxiliary connecting shaft 90 is provided on the outer side of the connecting shaft 904 located on the inner wall of the purification box 901. 4. Auxiliary holes for movement and rotation: A second bevel gear 906 is meshed with one side of the first bevel gear 905 and rotatably connected to the bottom end of the top rod 707 via a bearing. The second bevel gear 906 is installed between the first telescopic shaft 302 and the second telescopic shaft 303. The second bevel gear 906 is fixedly connected to the telescopic ends of the first telescopic shaft 302 and the telescopic ends of the second telescopic shaft 303. The interior of the purification box 901 is connected to the return pipe 907 through an opening leading to a one-way valve inside the return pipe 907.

[0049] The working principle of this invention is as follows: First, the molten material and the ingredients to be mixed with it are added into the stirring chamber 202 through the first feed port 5 and the second feed port 6. Then, the drive motor 301 is started, which drives the first telescopic shaft 302 to rotate. The first telescopic shaft 302 then drives the second telescopic shaft 303 to rotate. After the second telescopic shaft 303 rotates, it drives the horizontal plate 304 on its outer wall to rotate. During the rotation of the horizontal plate 304, it drives the stirring rod 305 inside to rotate. The stirring rod 305 then drives the stirring blade 306 to rotate, thereby achieving the mixing effect of the material. During the mixing process, the gas in the material is also discharged.

[0050] Furthermore, since the stirring blade 306 and the stirring rod 305 are arranged at an angle, the resistance of the stirring blade 306 to the material is reduced, resulting in energy saving for the drive motor. At the same time, during the rotation of the stirring rod 305, its top end moves in the auxiliary groove 402 on the end face of the guide plate 401. When the stirring rod 305 moves into the guide groove 403, it will shift laterally under the guidance of the guide groove 403. Meanwhile, the moving groove 404 of the horizontal plate 304 will also assist the lateral movement of the stirring rod 305, causing the stirring rod 305 to move at an angle. The angled stirring rod 305 will drive the stirring blade 306 to insert into the material at an angle before stirring, effectively improving the stirring quality. In addition, during the relative movement of the two sets of parallel and opposite stirring blades 306, they will knead the material between them, achieving a crushing effect on the ingredients and thus improving the mixing quality of the material.

[0051] In addition, during the reciprocating motion of the two sets of stirring blades 306, the material gap can be increased, which is conducive to the discharge of gas in the material and further improves the discharge of gas in the material.

[0052] While the second telescopic shaft 303 rotates, the groove 708 on its inner wall guides the guide rod 706. In other words, the guide rod 706 moves up and down reciprocally under the action of the rotating groove 708. Therefore, the guide rod 706 drives the vibrating block 701 to move up and down reciprocally. When the vibrating block 701 moves to the bottom of the second telescopic shaft 303, it will vibrate under the action of impact force. Correspondingly, the bottom plate 702 located on one side of the vibrating block 701 will also be affected by the vibration. Consequently, the material on the bottom plate 702 will also be affected by the vibration. At this time, the gas in the material will be accelerated to be discharged under the action of vibration, thereby achieving the effect of improving gas discharge.

[0053] Furthermore, as the second telescopic shaft 303 rotates, it will drive the drive shaft 804 to rotate, and the drive shaft 804 will in turn drive the fan blade 803 to rotate. The rotating fan blade 803 can generate negative pressure, which allows the gas in the stirring chamber 202 to enter the negative pressure box 801 through the air inlet 802 and be discharged to the purification box 901 through the air outlet 805.

[0054] When the gas enters the purification chamber 901, the activated carbon in the purification chamber 901 will adsorb and remove the harmful substances in the gas, thereby purifying the gas. Furthermore, the rotation of the first telescopic shaft 302 and the second telescopic shaft 303 will drive the second bevel gear 906 to rotate. Therefore, the second bevel gear 906 will drive the first bevel gear 905 to rotate. The first bevel gear 905 can drive the turntable 902 through the connecting shaft 904.

[0055] After the turntable 902 rotates, it will drive the multiple sets of stirring rods 903 on its end face to rotate, so that the stirring rods 903 can stir the activated carbon. At the same time, during the up and down movement of the vibrating block 701, the push rod 707 will move up and down under the action of the vibrating block 701. Therefore, under the action of the push rod 707, the second bevel gear 906 will also move up and down, thereby enabling the first bevel gear 905, the connecting shaft 904, the turntable 902, and the stirring rods 903 to move up and down.

[0056] The combination of up-and-down movement and rotation of the stirring rod 903 allows for random repositioning of the activated carbon in all directions, thereby maximizing the utilization of each activated carbon molecule and effectively preventing the problem of some activated carbon being fully loaded while others are unloaded. This ensures the overall adsorption quality of the activated carbon and improves the quality of gas purification.

[0057] It is worth noting that the purified gas will flow into the cavity 205 through the return pipe 907, which will have a heat preservation effect on the stirring chamber 202 and further improve the stirring quality of the material.
