In order to directly use composite materials with appropriate ratios when making products using composite materials, the existing technology can obtain fully composite granular materials by weighing the specific gravity and then mixing and melting. However, the composite material needs to be weighed every time it is obtained, and practical weighing tools and additional containers are used in the process, which is cumbersome to operate. Summary of the Invention

The outside of the funnel is provided with an electric heating ring, which is suitable for melting the granular material in the funnel. The lower end of each funnel is provided with a metering pump, and the output ends of all the metering pumps are fixedly connected to an injection assembly. The injection assembly includes a mixing barrel, one end of the mixing barrel is fixedly connected to a reduction motor, and the output end of the reduction motor is fixedly connected to a screw. The screw is located in the mixing barrel and is suitable for mixing raw materials from different raw material bins without repeated weighing, and can continuously feed.

[0005] As a preferred embodiment, a heat-insulating cylinder is fixedly connected to the outside of the storage cylinder, and the outer shell of the funnel is provided with a heat-insulating bucket, which is suitable for wrapping all the electric heating rings for melting solid materials.

[0006] Preferably, the metering pump includes a transmission box, the top of the transmission box is fixedly connected to a motor, the front of the transmission box is fixedly connected to a cylinder, and the input end of the cylinder is fixedly connected to the lower end of the funnel, so as to quantitatively suck the melted material out of the raw material bin.

[0007] Preferably, a feed port penetrating the inner and outer walls is provided on the top of the mixing barrel, the number of the feed ports is not less than the number of the metering pumps, and the output end of the cylinder body is connected to the feed port for pressing the molten raw material into the mixing barrel.

[0008] As a preference, one end of the mixing barrel has a mounting ring, the housing of the reduction motor is fixedly connected to the mounting ring, and the other end of the mixing barrel has a discharge cone, through which the molten raw materials in the mixing barrel are squeezed out.

[0009] As a preference, the mounting ring is provided with an axial hole coaxial with the mixing barrel, suitable for cooperating with the main shaft of the screw to form a rotating pair, thereby limiting the freedom of the screw and ensuring the rotational stability of the screw.

[0010] As a preferred embodiment, the metering pump and the raw material bin are fixedly connected to a mounting bracket, the mounting bracket is fixedly arranged, the mounting bracket includes a top plate, the top plate is provided with a configuration hole, the top plate is fixedly connected with a reinforcement ring around the configuration hole, the insulation tube passes through the configuration hole and is fixedly connected to the reinforcement ring to ensure the stable position of each raw material bin.

[0011] As a preference, the rear side of the top plate also has an integrated side plate, and the motor is fixedly connected to the side plate through a mounting plate to ensure the stability of each metering pump and prevent the input and output ends of the cylinder body from being subjected to greater stress.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] (1) By arranging an independent metering pump at the bottom of each raw material bin and controlling the feeding speed of each metering pump by a computer, different raw materials can be fed into the mixing barrel and mixed in a set ratio at any time without weighing each time. Moreover, the mixing process can be continuous and uninterrupted without the use of weighing tools and additional storage containers, making the process of obtaining composite particles more convenient and efficient.

[0014] (2) By setting a heating structure at the bottom of the raw material bin 3, the solid raw materials located above the raw material bin naturally form an insulation layer. The raw material bin without a top cover is more convenient for adding materials and observing, and the side walls of the raw material bin also have an insulation structure, which reduces the energy consumption required for heating. Therefore, the feeding system is more energy-efficient than the existing technology. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 1-8 The feeding system for composite particle production shown in FIG3 includes several raw material bins 3, which are usually arranged side by side at the same horizontal height. The types of particles stored in each raw material bin 3 are generally different. The raw material bin 3 has a cylindrical storage barrel 301, and the lower end of the storage barrel 301 has a funnel 302 with a large upper end and a small lower end. The upper end of the funnel 302 is the same size as the lower end of the storage barrel 301. An electric heating ring 305 is provided on the outside of the funnel 302 for melting the granular material in the funnel 302. In order to reduce energy consumption, an insulation barrel 303 is fixedly connected to the outside of the storage barrel 301, and an insulating bucket 304 is provided on the outer cover of the funnel 302. The insulating bucket 304 can wrap all the electric heating rings 305 to prevent the main heat source from losing heat to the outside.

[0029] A metering pump 2 is provided at the lower end of each funnel 302, which can transfer a precise volume of molten material per unit time. The output ends of all metering pumps 2 are fixedly connected to an injection assembly 1 for exporting the mixed material. The specific structure of the metering pump 2 includes a transmission box 202, and the interior of the transmission box 202 has a reduction mechanism and a crank structure. The top of the transmission box 202 is fixedly connected to an electric motor 201, and the output end of the electric motor 201 is connected to the input end of the transmission box 202. The front of the transmission box 202 is fixedly connected to a cylinder body 203, and a reciprocating piston is arranged in the cylinder body 203, and the piston is driven by the crank structure in the transmission box 202. The specific structure of the metering pump 2 belongs to a relatively mature existing technology and is no longer shown in the drawings. The input end of the cylinder body 203 is fixedly connected to the lower end of the funnel 302 for sucking the molten material in the funnel 302 into the cylinder body 203.

[0030] The injection assembly 1 includes a mixing barrel 110. The mixing barrel 110 is a place where various molten materials are mixed. The top of the mixing barrel 110 is provided with a feed port 111 that passes through the inner and outer walls. The feed port 111 is a channel for the molten material to enter the mixing barrel 110. In order to ensure that each material can enter through the feed port 111, the number of the feed ports 111 is not less than the number of the metering pumps 2. In actual assembly, the extra unused feed ports 111 will be sealed by the end cover structure to ensure that To ensure the sealing of the mixing barrel 110, the output end of the cylinder 203 is connected to the feed port 111, and the molten material in the cylinder 203 is pressed into the mixing barrel 110 through the feed port 111. One end of the mixing barrel 110 is fixedly connected to a reduction motor 120. Although the output speed of the reduction motor 120 is relatively low, the torque is relatively large, which is suitable for stably pushing the molten material to move. One end of the mixing barrel 110 has a mounting ring 113, and the housing of the reduction motor 120 is connected to the mounting ring 113. The mixing barrel 110 is directly fixedly connected with 13, and the other end of the mixing barrel 110 is provided with a discharge cone 112, from which the mixed molten material is discharged and re-cooled to form mixed particles after discharge. The output end of the reduction motor 120 is fixedly connected with a screw 130. The propeller blade structure on the outer side of the screw 130 can mix different materials when it rotates, and at the same time push the mixed materials to be discharged toward the discharge cone 112. The mounting ring 113 is provided with an axial hole 114 coaxial with the mixing barrel 110, which is used to cooperate with the main shaft of the screw 130 to form a rotating pair. A bearing structure is usually also provided in the axial hole 114 to reduce the friction of the screw 130 when it rotates, so that the rotation of the screw 130 is smoother. The vast majority of the screw 130 is located in the mixing barrel 110. In fact, the part of the screw 130 with the propeller blade is all located in the mixing barrel 110, and the length of the propeller blade along the axis is very close to the total length of the inside of the mixing barrel 110, so that the raw materials coming down from different raw material bins 3 can be fully mixed.

[0031] The metering pump 2 and the raw material bin 3 are fixedly connected to the same mounting bracket 4, which is fixedly arranged on a rack or a wall. The specific structure of the mounting bracket 4 includes a top plate 402, and the top plate 402 is provided with a configuration hole 403 passing through the upper and lower surfaces. The top plate 402 is fixedly connected with a reinforcement ring 404 around the configuration hole 403. The combination of the configuration hole 403 and the reinforcement ring 404 is not less than the number of raw material bins 3 actually used. All the insulation cylinders 303 are fixedly connected to the reinforcement ring 404 through a configuration hole 403, thereby ensuring the stability of all raw material bins 3. The rear side of the top plate 402 also has an integrated side plate 401, which is perpendicular to the top plate 402, the top plate 402 is in the horizontal direction, and the side plate 401 is in the vertical direction, with a reinforcement plate structure between the two. The motor 201 is fixedly connected to the side plate 401 through the mounting plate 204 to ensure the stability of all metering pumps 2.

[0032] Working principle: When in use, different granular materials are poured into different raw material bins 3, and the electric heating ring 305 at the bottom of each raw material bin 3 is started. The granular material is heated by the electric heating effect, and the solid particles are turned into fluid materials. Since the granular material in the storage barrel 301 is relatively far away from the electric heating ring 305, most of it remains in a solid state, and the thermal conductivity of the granular material is relatively poor, and a thick insulation layer is formed on the top of the molten material, so there is no need to add a lid to the top of the raw material bin 3, and the heat utilization rate is also relatively high. The raw material bin 3 with an open top is more convenient for continuing to add materials and observing the remaining amount of particles. The molten material is pumped down by the started metering pump 2 and pressed into the mixing barrel 110. Because the pumping speed of the metering pump 2 can be set more accurately, it is only necessary to set the speed ratio, and various raw materials can be installed in the same volume ratio into the mixing barrel 110. Under the stirring action of the screw 130 blades, different The molten materials can be roughly mixed and pushed toward the end where the discharge cone 112 is located. Of course, due to the different initial positions of different raw materials entering the mixing barrel 110, the composite materials are not in the desired proportion at the beginning, so the material extruded by the injection assembly 1 at the beginning is not used. When the injection barrel 110 is filled, the proportion of the mixed materials extruded subsequently is correct. The mixed material with the correct proportion is extruded from the discharge cone 112 and cooled, and then cut into particles again, which are the target mixed particles. After the use of the equipment is over, the metering pump 2 and the screw 130 must continue to run for a period of time to empty the material in the body as much as possible to avoid the material solidifying in the body and affecting subsequent normal operation. After the system has been used once, the cylinder 203 and the mixing barrel need to be preheated when used again to melt the residual material that may solidify again to avoid the presence of solidified material in undetected parts affecting the normal startup of the moving parts.
