Description

Technical Field

[0001] The utility model relates to the technical field of plastic product production, in particular to an automatic feeding component for plastic particles. Background Art

[0002] Plastic products are a general term for daily and industrial products made from plastic as the main raw material. They include products made from injection molding, blister molding, and other processes that use plastic as the raw material. During production, the raw material, i.e., plastic particles, needs to be added.

[0003] The existing plastic pellet feeding assembly requires workers to lift the plastic pellets and pour them into the silo. Since the plastic pellets have a certain weight, manual feeding is labor-intensive and inefficient. In addition, since the plastic pellets are easily squeezed against each other when stacked, it is easy to cause the silo discharge port to be blocked, affecting the discharge of the material. Utility Model Content

[0004] The utility model aims to provide an automatic feeding assembly for plastic particles to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic feeding assembly for plastic particles, comprising a silo, a feeding port is provided at the bottom end of the silo, a feeding cabin is provided below the feeding port, gantries are provided on the outer surfaces of both ends of the silo, and the top of the gantry extends to the top of the silo, a rotating roller is provided on the top of the gantry, and two conveying crawlers are provided on the outer surface of the rotating roller of the gantry, and the ends of the two conveying crawlers are commonly connected to a driving roller, and two limiting pulleys are provided on the outer surfaces of the rotating roller and the driving roller near the corresponding conveying crawler positions, the inner sides of the two conveying crawlers are commonly connected to a column, a connector is provided at the center position of the column, and a feeding box is provided at the bottom end of the connector.

[0006] Preferably, four support columns are arranged in a ring on the outer surface of the silo below the gantry, and fixed frames are provided on the surfaces of the four support columns. The head ends of the four fixed frames are commonly connected to the outer surface of the feeding cabin to support the silo and the feeding cabin, thereby ensuring the stability of the automatic feeding assembly of the plastic particles.

[0007] Preferably, a rotating rod is provided at the bottom of the discharge port, a spiral protrusion is provided on the outer surface of the rotating rod, bearings are provided at both ends of the rotating rod, the bearings are fixedly connected to the inside of the discharge port, and one end of the rotating rod extends out of any bearing, a driving motor is provided at the extended end of the rotating rod, a support frame is provided on the outer surface of the driving motor, and the top of the support frame is fixedly connected to the outer surface of the discharge port. When the loading box puts plastic particles into the silo, the plastic particles will accumulate, and the plastic particles at the bottom of the discharge port are stacked on each other, which may easily cause the discharge port to be stuck, resulting in failure to discharge normally. The driving motor drives the rotating rod to drive the spiral protrusion to rotate, causing the plastic particles at the bottom to shake, thereby preventing the discharge port from being blocked.

[0008] Preferably, an opening is provided at the top of the feeding box, and an electromagnetic valve is provided at the discharge port at the bottom of the feeding box. The electromagnetic valve is wirelessly controlled, and the electromagnetic valve is opened when unloading, and the electromagnetic valve is closed when the staff pours the plastic granular raw materials into the feeding box, thereby improving the feeding efficiency.

[0009] Preferably, support poles are provided at both ends of the driving roller, and the tops of the support poles are lower than the top of the gantry, so as to support the driving roller and make the conveying crawler in an inclined state, thereby ensuring the stability of the device.

[0010] Preferably, any section of the driving roller is provided with a forward and reverse control motor, and a stabilizing frame is provided on the surface of the forward and reverse control motor, so that the forward and reverse control motor can drive the driving roller to rotate so that the conveying crawler can run.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. This automatic feeding component for plastic pellets drives the feeding box to run with a height difference through the inclined conveyor track, which is convenient for lifting the plastic pellets above the silo for feeding. There is no need for manual lifting, which reduces labor intensity and improves feeding efficiency.

[0013] 2. The automatic feeding component of plastic particles is provided with a rotating rod with a spiral protrusion inside the feeding port, so that the plastic particles at the bottom are stirred and shaken, so as to avoid the plastic particles squeezing each other and blocking the feeding port, resulting in failure of normal feeding, thereby improving production efficiency.

The inner sides of the two conveyor crawlers 12 are commonly connected to the column 11. The driving roller 21 and the rotating roller 20 rotate, so that the conveyor crawler 12 can achieve the effect of driving the column 11 to perform linear motion. A connector 10 is provided at the center position of the column 11, and a loading box 9 is provided at the bottom end of the connector 10. The connector 10 and the column 11 are rotatably connected. When the conveyor crawler 12 drives the column 11 to perform linear motion, the loading box 9 can be transported from a low place to a high place above the silo 1, and there is no need to manually lift the plastic granule raw materials, thereby reducing labor intensity and improving efficiency.

[0021] Furthermore, four support columns 3 are arranged in a ring on the outer surface of the silo 1 below the gantry 13, and fixed frames 4 are provided on the surfaces of the four support columns 3. The head ends of the four fixed frames 4 are commonly connected to the outer surface of the feeding chamber 5, supporting the silo 1 and the feeding chamber 5 to ensure the stability of the automatic feeding assembly of the plastic particles.

[0022] Furthermore, a rotating rod 17 is provided at the bottom of the discharge port 2, and a spiral protrusion 18 is provided on the outer surface of the rotating rod 17. Bearings 19 are provided at both ends of the rotating rod 17.

[0026] The method of using this embodiment is as follows: the electrical components appearing in this application are all connected to an external power supply when in use, and the automatic feeding assembly for material particles is used to start the forward and reverse control motor 8 to drive the conveyor crawler 12 to transport the loading box 9 from the top of the silo 1 to a lower position, and the staff then pours the plastic granule raw materials into the loading box 9 through the opening 14, and then transports the loading box 9 to the top of the silo 1 through the conveyor crawler 12. A valve is provided at the bottom of the loading box 9. At this time, the valve is opened again, and the plastic particles will fall into the silo 1 due to gravity, and then the driving motor 16 is turned on, and the spiral protrusion 18 is driven to rotate by the rotating rod 17. The spiral protrusion 18 stirs the plastic particles at the bottom of the discharge port 2 to cause shaking, so as to avoid the plastic particles squeezing each other to cause the discharge port 2 to be blocked, so that the plastic particles fall into the feeding cabin 5 and are then transported to the subsequent processing device.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
