Technical Field
[0001] The present application relates to the technical field of quantitative packaging of plastic pellets, and in particular to a plastic pellet weighing and packaging device. Background Art
[0002] Plastic pellets refer to small granular materials made by mixing, heating, melting, extruding, fine filtering, granulating and other processes under certain conditions according to the properties and uses of plastics. Plastic pellets are widely used in the manufacture of various plastic products, such as automobiles, electronics, daily necessities, building materials and other industries.
[0003] Plastic pellets need to go through weighing, packaging and other processes before they can be put on the market. Weighing and packaging operations consume a lot of manpower and time, and are inefficient. Many manufacturers have adopted packaging machines with automatic weighing to package materials. The current weighing packaging machines mainly include a storage barrel, a power mechanism, a weighing mechanism and a discharge port. A large amount of plastic pellets are stored in the storage barrel, and the plastic pellets fall into the packaging bag from the discharge port. When a certain weight is reached, the power mechanism closes the discharge port to achieve the purpose of quantitative packaging.
[0004] Regarding the above-mentioned related technologies, since the plastic particles have certain elasticity and viscosity, they will stick to each other and form lumps after being squeezed for a long time in the storage tank, resulting in blockage of the discharge port. Therefore, there is still a lot of room for improvement. Utility Model Content

[0030] The following is combined with Figure 1-2 This application is described in further detail.
[0031] The present application discloses a device for weighing and packaging plastic pellets. Figure 1 The plastic pellet weighing and packaging device includes a frame 1, a weighing piece 2, a storage barrel 3, a stop assembly 4, a lower hopper 5 and a breaking assembly 6, wherein the storage barrel 3 is fixedly mounted on the frame 1 for storing plastic pellets, the stop assembly 4 is mounted on the storage barrel 3 for controlling the discharge of the storage barrel 3, the lower hopper 5 is fixedly mounted on the frame 1 and located below the storage barrel 3, the breaking assembly 6 is fixedly mounted in the lower hopper 5 for breaking up the plastic pellets that are stuck together, and the weighing piece 2 is fixedly mounted on the frame 1 and located below the lower hopper 5 for weighing the weight of the plastic pellets.
[0032] The prepared plastic pellets need to be bagged before being put on the market for sale. When bagging, the weight of each bag of plastic pellets needs to be kept consistent, so a weighing piece 2 is provided. Specifically, the weighing piece 2 is an electronic scale, which is fixedly installed at the bottom of the frame 1. The bag for plastic pellets is placed on the weighing piece 2, and the plastic pellets continuously fall into the bag for loading. The value on the weighing piece 2 keeps changing, and the loading is stopped when a certain value is reached.
[0033] refer to Figure 2 The storage barrel 3 is installed at the top of the frame 1 and is used to store a large amount of plastic pellets. Specifically, the storage barrel 3 is a box structure with an opening at the top of the storage barrel 3 for filling the plastic pellets to be bagged. In order to reduce the possibility of other foreign matter falling into the storage barrel 3, a cover 7 is rotatably installed at the opening at the top of the storage barrel 3, and a handle 71 is fixedly installed on the cover 7. Since the cover 7 is relatively heavy as a whole, the handle 71 is convenient for the staff to flip the cover 7 to fill the plastic pellets; a discharge port 31 is opened at the bottom of the storage barrel 3, and the plastic pellets in the storage barrel 3 fall from the discharge port 31 into the lower hopper 5.
[0034] refer to Figure 1 and Figure 2 In order to control the plastic pellets from falling from the discharge port 31, a stop assembly 4 is installed on the storage barrel 3 to block or keep away from the discharge port 31. Specifically, the stop assembly 4 includes a second power element 41 and a baffle 42, wherein the second power element 41 is installed on the storage barrel 3. In this embodiment, the second power element 41 is a telescopic cylinder, which is rotatably installed on the side wall of the storage barrel 3, and the baffle 42 is also rotatably installed on the storage barrel 3. The telescopic rod of the telescopic cylinder is rotatably connected to the baffle 42, and the baffle 42 surrounds the discharge port 31 on the storage barrel 3. When the telescopic rod of the telescopic cylinder is retracted, the baffle 42 blocks the discharge port 31. 1. The plastic pellets cannot fall out of the storage barrel 3. When the telescopic rod of the telescopic cylinder is extended, the baffle 42 is pushed to rotate. At this time, the baffle 42 is moved away from under the discharge port 31, and the plastic pellets in the storage barrel 3 fall out. This process only requires the telescopic cylinder to drive the baffle 42 to rotate to complete, which is simple and efficient. At the same time, the baffle 42 is an arc-shaped baffle 42 with a certain curvature. The curvature of the baffle 42 is conducive to surrounding the storage barrel 3 and reducing the possibility of plastic pellets falling out from the edge of the baffle 42. When the baffle 42 is moved away from the discharge port 31, the curvature of the baffle 42 also plays a certain guiding role, guiding some plastic pellets to slide into the lower hopper 5.
[0035] In other embodiments, a power element that outputs linear reciprocating motion, such as a screw stepper motor or a piston, may be used instead of the telescopic cylinder to drive the baffle 42 to rotate, and its specific solution will not be described in detail here.
[0036] refer to Figure 1In order to improve the accuracy of the charging weight, a sensor and a PLC controller are also provided. The sensor is electrically connected to the weighing piece 2 and the PLC controller respectively, and the second power element 41 is electrically connected to the PLC controller. The sensor continuously monitors the weight on the weighing piece 2 and transmits the weight information to the PLC controller. The PLC controller analyzes the signal. When the weight on the weighing piece 2 reaches a certain value, the PLC controller generates a control signal to control the second power element 41 to start, drive the baffle 42 to block the discharge port 31 on the storage barrel 3, thereby stopping the charging, which is beneficial to improving the stability and accuracy of the charging weight. The sensor and the PLC controller are not specifically displayed in the accompanying drawings.
[0037] refer to Figure 1 In order to facilitate loading, a lower hopper 5 is provided, and the lower hopper 5 plays a role in improving the loading accuracy. Specifically, the lower hopper 5 includes a conical hopper 51 and a columnar channel 52, wherein the conical hopper 51 is fixedly mounted on the frame 1, the conical hopper 51 is trumpet-shaped, and has a larger opening and a smaller opening, and a uniform transition from the larger opening to the smaller opening, the larger opening end is vertically upward, and the smaller opening end is vertically downward, and the larger opening end of the conical hopper 51 helps to collect the plastic pellets falling from the baffle 42, thereby reducing the loss and waste of the plastic pellets; the columnar channel 52 is vertically arranged and fixedly mounted on the conical hopper 51, and is integrally connected to one end of the smaller opening of the conical hopper 51, and the plastic pellets accurately fall into the bag through the columnar channel 52, thereby improving the loading accuracy.
[0038] refer to Figure 1 and Figure 2 Since the plastic pellets have certain elasticity and viscosity, when the plastic pellets are piled together for a long time, the plastic pellets will stick to each other. During the loading process, the plastic pellets that stick together will block the lower hopper 5, making the loading process unable to proceed smoothly. Therefore, a breaking component 6 is provided. Specifically, the breaking component 6 includes a first power element 61, a rotating shaft 62 and a plurality of blades 63. The first power element 61 is installed in the lower columnar channel 52. In this embodiment, the first power element 61 is a motor, which is vertically arranged, and the output shaft of the motor is vertically downward and fixedly installed in the columnar channel 52 for outputting power; the rotating shaft 62 is also vertically arranged and fixedly installed on the output shaft of the motor. The motor is used to drive the rotating shaft 62 to rotate, and the plurality of blades 63 are fixedly installed on the surface of the rotating shaft 62; the plurality of blades 63 are strip structures, one end of the plurality of blades 63 is fixedly installed on the rotating shaft 62, and the plurality of blades 63 are staggered with each other, which increases the possibility of collision between the sticking plastic pellets and the blades 63, is conducive to breaking up the sticking plastic pellets, and at the same time improves the breaking efficiency.
[0039] In the embodiment, the blades 63 are made of silicone material. Silicone has a certain elasticity. While being able to break up the adhering plastic particles, it will not cut or break the plastic particles, which helps to maintain the integrity of the plastic particles. When the motor rotates, a number of blades 63 rotate with the rotating shaft 62, and a number of blades 63 break up the adhering plastic particles. In other embodiments, the first power element can also be a power element with output torque such as a rotating cylinder or a pneumatic motor instead of a motor to drive the rotating shaft 62 to rotate. The specific scheme is not repeated here.
[0040] refer to Figure 2 As more and more materials are loaded, the bag may tilt, causing the loaded plastic pellets to scatter out. Therefore, a hook body 8 is fixedly installed on the frame 1. In this embodiment, four hook bodies 8 are provided, wherein two hook bodies 8 are installed at intervals on one side of the frame 1, and the other two hook bodies 8 are installed at intervals on the side opposite to the first two hook bodies 8, and the four hook bodies 8 are located below the lower hopper 5. The bag can be hung on the structure, and the bag is fixed, which is conducive to smooth loading.
