Background Art

[0002] Plastic raw materials are typically granular and used to produce various plastic products. Depending on the product requirements, a single plastic raw material, or a mixture of two, three, or more plastic raw materials, or a modified mixture of one, two, three, or more colors may be used. During production, the various (colored) plastic raw materials need to be metered, stirred, and mixed. Chinese Patent Publication No. 222201206 U discloses a "Plastic Particle Mixing and Weighing Device and Plastic Color Matching Machine," comprising a mixing housing with a mixing chamber, a weighing container disposed within the mixing chamber, the weighing container fixedly connected to the mixing housing via a weighing sensor, a plurality of feed vessels disposed on the mixing housing, each of which is connected to the inner cavity of the weighing container, each of which is used to hold a different type of plastic granules, a weighing outlet disposed at the bottom of the weighing container, the weighing valve assembly being capable of blocking or opening the weighing outlet, and a mixing discharge port disposed at the bottom of the mixing housing.

[0003] The disadvantages of this device are: 1. It uses weighing measurement, and the weighing sensor is prone to false alarm accidents due to uneven accumulation of raw materials, resulting in inaccurate measurement; 2. There is no stirring element in the mixing shell, which easily leads to uneven mixing of various plastic raw materials. Summary of the Invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a particle metering and discharging device that adopts a volumetric metering method and has more accurate metering.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A particle metering and discharging device comprises a bottom plate, a discharging port is arranged on the bottom plate, a volume metering component is arranged on the discharging port, and a material storage container is arranged on the volume metering component.

[0006] Furthermore, the volume metering component includes a box body, in which a roller is rotatably arranged, and a plurality of evenly distributed volume metering grooves are arranged on the circumference of the roller. Both sides of the roller are provided with material blocking components for blocking the volume metering grooves on both sides of the roller. A feed port is arranged on the box body, the volume metering groove on the upper side of the roller corresponds to the feed port, the material storage container is connected to the feed port, and the volume metering groove on the lower side of the roller corresponds to the discharge port.

[0007] Furthermore, a rotating shaft is passed through the drum, a motor fixing plate is provided on the bottom plate, a motor is provided on the motor fixing plate, an output shaft of the motor is connected to one end of the rotating shaft, an axle seat is provided on the box body, and the other end of the rotating shaft is placed on the axle seat.

[0008] Furthermore, the motor is a stepping motor, and a rotation number detection head of the rotating shaft is set on the output shaft of the stepping motor.

[0009] Furthermore, the material stop assembly includes a long material stop block, a short material stop block and an upper material stop block. The inner side surfaces of the long material stop block and the short material stop block are in contact with the circumferential surface of the drum. There are two upper material stop blocks, which are respectively in contact with the upper sides of both ends of the drum.

[0010] Furthermore, the long stop block, the short stop block and the upper end stop block can be integrally formed.

[0011] Furthermore, a box cover is provided on the box body, a feed port is provided on the box cover, a joint is provided on the feed port, and a material storage container is connected to the joint.

[0012] Furthermore, there are 2-10 volume measuring tanks.

[0013] Furthermore, two sets of volume measuring components are provided in the box body.

[0014] Another object of the present invention is to provide a stirring and mixing device, comprising any one of the above-mentioned particle metering and discharging devices, wherein a mixing mechanism is provided under the particle metering and discharging device.

[0015] Furthermore, the mixing mechanism includes a mixing container, which is funnel-shaped, and the funnel mouth is the mixing outlet. A shelf is provided on the mixing container, and the particle metering and discharging device is provided on the shelf. A mixing inlet is provided on the shelf, and the discharge port of the particle metering and discharging device corresponds to the mixing inlet.

[0016] Furthermore, a stirring assembly is provided in the mixing outlet, and the stirring assembly includes a stirring shaft axially passed through the mixing outlet, a stirring frame is provided on the stirring shaft, a stirring motor is provided on the outer wall of the mixing container, and one end of the stirring shaft extends out of the mixing container and is connected to the output shaft of the stirring motor.

[0019] A particle metering and discharging device of the present invention adopts volume metering. The volume metering component is composed of a plurality of evenly distributed volume metering grooves arranged on the circumference of the drum. The volume (capacity) of the volume metering groove is preset, and the drum is also driven to rotate by power with preset speed parameters. During operation, when a volume metering groove starts to be filled until the volume metering groove is filled, the drum rotates synchronously, just driving the volume metering groove to flip over. Since the blocking components are provided on both sides of the drum, the raw materials will not fall out at this time until they flip over to the top of the discharge port, and the raw materials fall into the discharge port to complete the discharge. The total amount of discharge can be calculated based on the capacity of the volume metering groove multiplied by the number of volume metering grooves and the number of rotations. When the total amount of discharge reaches the preset requirements, the discharge is stopped.

[0020] This solution has multiple volume metering slots that are evenly arranged, which can achieve continuous and stable metering and discharging. Compared with existing weighing and metering, the metering is more accurate, there is no false alarm, and the production efficiency is higher.

DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to specific implementation cases. The following implementation cases will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form.

[0024] like Figure 1 — Figure 5 As shown, the present invention relates to a particle metering and discharging device, comprising a base plate 1, a discharge port 2 is arranged on the base plate, a volume metering component is arranged on the discharge port 2, a storage container 3 is arranged on the volume metering component, the volume metering component comprises a box body 5, a roller 6 is rotatably arranged in the box body 5, a plurality of evenly distributed volume metering grooves 7 are arranged on the circumference of the roller 6, and blocking components for blocking the volume metering grooves 7 on both sides of the roller 6 are provided on both sides of the roller 6, a feed port 8 is arranged on the box body 5, the volume metering groove 7 on the upper side of the roller 6 corresponds to the feed port 8, the storage container 3 is connected to the feed port 8, and the volume metering groove 7 on the lower side of the roller 6 corresponds to the discharge port 2.

[0025] During operation, when a volumetric metering trough 7 begins to fill until it is full, the roller 6 rotates synchronously, just causing the volumetric metering trough 7 to flip over. Due to the material blocking components on both sides of the roller 6, the raw materials will not fall out at this time until the volumetric metering trough 7 flips over to the discharge port 2, at which point the raw materials fall from the volumetric metering trough 7 into the discharge port 2, completing the discharge. The total amount of material discharged can be calculated by multiplying the capacity of the volumetric metering trough by the number of volumetric metering troughs and the number of rotations of the roller. When the total amount of material discharged reaches the preset requirement, the material is stopped.

[0026] Furthermore, a rotating shaft 9 is passed through the roller 6, a motor fixing plate 4 is provided on the bottom plate 1, a motor 10 is provided on the motor fixing plate, an output shaft of the motor 10 is connected to one end of the rotating shaft 9, an axle seat 11 is provided on the box body 5, and the other end of the rotating shaft 9 is placed on the axle seat 11. The motor 10 is a stepper motor, and a rotation number detection head 12 of the rotating shaft 9 is provided on the output shaft of the stepper motor. The roller 6 is driven to rotate by the stepper motor, and the rotation is stable and reliable. The rotation number detection head 12 can record the number of rotations of the roller, which is convenient for calculating the total amount of discharge.

[0027] Furthermore, the material blocking assembly includes a long material blocking block 15, a short material blocking block 16 and an upper material blocking block 17. The inner side surfaces of the long material blocking block 15 and the short material blocking block 16 are in contact with the circumferential surface of the roller 6. The upper material blocking block 17 has two pieces, which are respectively in contact with the upper sides of both ends of the roller 6 to effectively prevent the raw material from leaking. The long material blocking block 15, the short material blocking block 16 and the upper material blocking block 17 can be made as a whole or separately, and each is fixed on the box body 5 and the box cover 18.

[0028] Furthermore, the box body 5 is provided with a box lid 18, the feed port 2 is provided on the box lid 18, and the feed port is provided with a joint 19, to which the storage container 3 is connected. Due to the large volume of the storage container, the joint facilitates the parallel placement of multiple storage containers. For example, if two sets of volumetric metering assemblies are provided in the box body 5, two corresponding storage containers are required to meter and discharge two raw materials. The number of volumetric metering slots 7 can be 2-10, and the specific number can be determined according to actual production requirements. However, the more volumetric metering slots there are, the smaller the capacity of each volumetric metering slot is, and the faster the rotation speed of the drum is.

[0029] The present invention also relates to a stirring and mixing device, such as Figure 6 —9 shows a particle metering and discharging device comprising two or more groups of any one of the above items, a mixing mechanism 20 is arranged under the particle metering and discharging device, the mixing mechanism 20 comprises a mixing container 21, the mixing container 21 is funnel-shaped, the funnel mouth is a mixing outlet 22, a shelf 23 is arranged on the mixing container, the particle metering and discharging device is arranged on the shelf 23, a mixing inlet 24 is arranged on the shelf 23, and the discharge port 2 of the particle metering and discharging device corresponds to the mixing inlet 24.

[0030] Mixing is the process of mixing two or more raw materials. Therefore, two or more particle metering and discharging devices are provided on the shelf 23. When two or more raw materials fall into the mixing container 21, the raw materials will automatically mix and converge at the funnel mouth after free fall due to the funnel shape of the mixing container 21. The funnel mouth is the mixing outlet 22, which can be connected to an external suction machine to transport the mixed raw materials to the production equipment. Suction machines are existing technology and are available on the market. A gate 29 can also be provided on the mixing outlet 22. Instead of connecting to an external suction machine, the mixing device can be placed on a high platform, and the mixing outlet 22 will directly discharge the material. The gate 29 facilitates shutdown for inspection and maintenance.

[0031] Furthermore, a stirring assembly is provided in the mixing outlet 22. The stirring assembly includes a stirring shaft 25 axially extending through the mixing outlet 22, a stirring frame 26 disposed on the stirring shaft, and a stirring motor 27 disposed on the outer wall of the mixing container 21. One end of the stirring shaft 25 extends out of the mixing container 21 and is connected to the output shaft of the stirring motor 27. The stirring motor 27 drives the stirring shaft 25, which in turn drives the stirring frame 26 to rotate, stirring the falling raw materials, thereby fully mixing the two or more raw materials and achieving uniform mixing.

[0032] Furthermore, a bracket 28 is provided under the mixing container 21. With the bracket, the stirring and mixing device can be placed on the ground.

[0033] Furthermore, 2-8 groups of particle metering and discharging devices are provided on the shelf 23. One group of particle metering and discharging devices can discharge one or two raw materials. Therefore, the specific number of groups can be determined according to actual production conditions.

[0034] The above specific embodiments are used to illustrate the present invention rather than to limit the present invention.
