[0002] Glass fiber reinforced nylon is an engineering plastic modified by adding glass fibers and toughening agents to nylon resin, exhibiting good dimensional stability and creep resistance. Currently, in the preparation and production process of glass fiber reinforced nylon, a certain proportion of glass fiber reinforcing agent, toughening agent, and lubricant is typically added to the nylon resin raw material. However, in actual proportioning, the dosage of these components requires manual weighing in four separate containers. These containers are then repeatedly weighed until the total weight reaches the specified proportion. Finally, the materials are injected into a mixer for mixing. Therefore, the manual weighing and proportioning process in the preparation and production of glass fiber reinforced nylon is cumbersome, and the inability to automatically weigh and proportion the four materials significantly reduces the production efficiency of glass fiber reinforced nylon.

[0040] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0041] like Figures 1-8 As shown, this utility model provides a proportioning device for preparing glass fiber reinforced nylon particles, including a column 3; a foot 2 is welded to the bottom end of the column 3, a ring frame 5 is welded to the top end of the column 3, a manifold 6 is welded to the inner side of the ring frame 5, a support frame 19 is welded to the outer side of the manifold 6, a control machine 18 is installed on the front side of the support frame 19, and a ring frame 4 is welded to the outer side of the column 3; it also includes a sleeve 12 and a material loading device 13; a drive motor 11 is installed at the top end of the sleeve 12, a transmission rod 17 is installed on the motor shaft of the drive motor 11, a rotating rod 15 is welded to the bottom end of the transmission rod 17, a bracket 7 is welded to the outer side of the sleeve 12 near the center position, a manifold 6 is welded to the outer side of the bracket 7, a support column 10 is welded to the upper side of the bracket 7, and a top plate 9 is welded to the top end of the support column 10.

[0042] In this embodiment of the utility model, the number of material loading devices 13 is four sets. Each set of material loading devices 13 includes a pressure plate 1301, a pull rod 1302, a storage cylinder 1303, and an electric butterfly valve 1304. The number of pull rods 1302 is four sets, and a storage cylinder 1303 is welded to the bottom end of each set of pull rods 1302. The storage cylinder 1303 is a cylindrical structure with an open upper side. The bottom of the cylindrical structure of the storage cylinder 1303 is a centripetal inclined conical structure. A circular pipe runs vertically through the center of the conical structure. The material to be prepared in the storage cylinder 1303 flows along the conical structure at the bottom of the storage cylinder 1303 to the circular pipe under the drive of gravity, which avoids the accumulation and waste of the material at the bottom of the storage cylinder 1303 and reduces the loss of the material. An electric butterfly valve 1304 is installed at the bottom of the circular pipe of the storage cylinder 1303. A pressure plate 1301 is welded to the top of each set of pull rods 1302. The pressure plate 1301 has a disc-shaped structure.

[0043] In this embodiment of the present invention, the top plate 9 is a disc-shaped structure. A weighing sensor 16 is installed on the upper side of the disc-shaped structure of the top plate 9. The upper side of the disc-shaped structure of the top plate 9 is provided with sixteen sets of through holes that run vertically through the top plate. Every four sets of through holes in the top plate 9 are arranged in a circular array around the vertical central axis of the top plate 9. The pull rod 1302 is inserted into the through holes of the top plate 9. The through holes of the top plate 9 guide the pull rod 1302, so that the pull rod 1302 drives the welded pressure plate 1301 to press the weighing sensor 16 vertically downward. The pressure plate 1301 presses the weighing sensor 16 downward in a horizontal posture, avoiding the horizontal torsional interference force from affecting the weighing result of the weighing sensor 16. This ensures that the weight of the material prepared in the storage cylinder 1303 is evenly transferred to the weighing sensor 16 for measurement, and ensures the weighing ratio accuracy of the material prepared in the storage cylinder 1303.

[0044] In this embodiment of the present invention, the manifold 6 is a cylindrical shell structure. A large through hole is provided at the center of the upper side of the manifold 6. The bracket 7 is welded into the large through hole of the manifold 6. Four sets of small through holes are provided at the top of the manifold 6 near the outer side. The bottom of the inner side of the cylindrical shell structure of the manifold 6 is a concentric inclined conical structure. A circular through pipe is provided at the center of the conical structure of the manifold 6. A material carrier 1 is placed on the bottom side of the circular through pipe of the manifold 6. The circular through pipe of the manifold 6 and the material carrier 1 are vertically opposite each other. The preparation material discharged from the four sets of storage cylinders 1303 flows along the conical structure at the bottom of the manifold 6 to the circular through pipe of the manifold 6 under the drive of gravity, preventing the preparation material from accumulating at the bottom of the storage cylinder 1303 and reducing the proportioning error caused by residual loss of preparation material.

[0045] In this embodiment of the present invention, a stirring rod 14 is welded to the outer side of the rotating rod 15 near the bottom end. There are three sets of stirring rods 14, which are arranged in a ring array around the vertical central axis of the rotating rod 15. During the process of the drive motor 11 driving the rotating rod 15 to rotate through the transmission rod 17, the rotating rod 15 drives the stirring rods 14 to rotate horizontally around the vertical central axis of the rotating rod 15 inside the circular passage of the manifold 6. The stirring rods 14 disperse the preparation material flowing into the circular passage of the manifold 6, so as to avoid the preparation material from flowing and clogging in the circular passage of the manifold 6, and ensure stable material discharge at the circular passage of the manifold 6.

[0046] In this embodiment of the utility model, there are four sets of weighing sensors 16. The weighing sensors 16 are arranged in a ring array around the vertical central axis of the top plate 9. The weighing sensors 16 are positioned vertically opposite the center of the lower side of the disc-shaped structure of the pressure plate 1301. The storage cylinder 1303 is driven by the pull rod 1302 to push the pressure plate 1301 downwards towards the measuring end of the weighing sensors 16. The weighing sensors 16 measure the weight of the prepared materials in the loading device 13 and the storage cylinder 1303. When the unloading control module of the controller 18 controls the electric butterfly valve 1304 to open, the prepared materials in the storage cylinder 1303 are discharged downwards from the circular pipe of the storage cylinder 1303. The weighing sensors 16 measure the discharged weight of the prepared materials in the storage cylinder 1303 in real time. When the discharged weight is equal to the proportion weight set by the controller 18, the unloading control module of the controller 18 controls the electric butterfly valve 1304 to close, thus realizing the automatic weighing, unloading and proportioning of the four sets of prepared materials. The weighing and proportioning operation is simple and quick.

[0047] Specific usage and function of this utility model embodiment:

[0048] In the preparation and proportioning of glass fiber reinforced nylon particles, an external power source supplies power to the power supply module of the control unit 18 via a wire. The control panel module of the control unit 18 then activates its motor control module, which in turn activates the drive motor 11. The drive motor 11, through the transmission rod 17, drives the rotating rod 15 to rotate. The rotating rod 15 then drives the stirring rod 14 to rotate horizontally within the circular conduit of the manifold 6. The nylon resin raw material, glass fiber reinforcing agent, toughening agent, and lubricant are first placed in four sets of material carriers 13. The material is placed in the storage cylinder 1303. Then, the weight ratio of the four sets of materials is input into the control operation panel module of the control machine 18. The control operation panel module of the control machine 18 transmits the weight ratio of the four sets of materials to the weighing detection control module of the control machine 18. The weighing detection control module of the control machine 18 controls the four sets of electric butterfly valves 1304 to open synchronously through the wires. At this time, the nylon resin raw material, glass fiber reinforcing agent, toughening agent and lubricant placed in the four sets of storage cylinders 1303 flow into the manifold 6 by gravity through the circular pipes of the four sets of storage cylinders 1303. Then the nylon resin Raw materials, glass fiber reinforcing agent, toughening agent, and lubricant flow into the circular passage of the manifold 6 along the conical structure of the manifold 6. The stirring rod 14 agitates the materials flowing into the circular passage of the manifold 6. Finally, the nylon resin raw materials, glass fiber reinforcing agent, toughening agent, and lubricant fall downwards into the loading basin 1 through the circular passage of the manifold 6. At this time, under the action of their own weight and the weight of the materials inside, the four sets of storage cylinders 1303 pull the four sets of pressure plates 1301 through the pull rods 1302 to squeeze the four sets of weighing sensors 16. The four sets of weighing sensors 16 then compress the four sets of storage cylinders 1303. The weight reduction of the prepared materials in the barrel 1303 is measured. Four sets of weighing sensors 16 transmit the weight reduction of the prepared materials to the weighing detection and control module of the controller 18 via wires. The weighing detection and control module of the controller 18 compares the weight reduction of the prepared materials with the input proportion weight of the materials. When the weight reduction of the prepared materials is equal to the proportion weight of the corresponding materials, the weighing detection and control module of the controller 18 controls the four sets of electric butterfly valves 1304 to close one by one via wires, thereby completing the preparation and proportioning of glass fiber reinforced nylon particles.

[0049] All the above components are installed, connected, or set up using common mechanical methods, such as welding, threaded connections, and screw connections. Furthermore, the specific structure, model, and coefficient indicators of all components are based on their own technologies, and any method that achieves the desired effect can be implemented. The drive motor 11, electric butterfly valve 1304, load cell 16, and controller 18 mentioned above are all common market components. When purchasing and using them, simply connect them according to the instruction manual purchased with the product; therefore, further details are omitted here.
