A plastic powder feeding machine

Abstract

The utility model discloses a plastic powder feeding machine, including the feeding machine mounting support, the main hopper of setting at its top and the distribution cylinder that is communicated with the main hopper through the blanking tube. The coaxial rotation of distribution cylinder is equipped with the rotating shaft, and is driven by the rotation drive structure. The rotating shaft is fixed with a receiving cylinder, and the outer wall of the receiving cylinder is in close contact with the inner wall of the distribution cylinder. The receiving cylinder is divided into several independent receiving bins by a plurality of partitions. Each receiving bin is provided with a second inlet. When the rotating shaft rotates, the second inlet of each receiving bin passes under the first inlet of the top of the distribution cylinder in turn, thereby periodically receiving powder from the main hopper.

The plastic powder feeding machine effectively solves the blockage and bridging problems that easily occur during the feeding process of plastic powder through the rotating receiving and mechanical linkage stirring method, realizes uniform, stable and continuous automatic feeding, and improves production efficiency and reliability.

Description

Technical Field

[0001] This utility model relates to the field of plastic powder production feeding, specifically to a plastic powder feeding machine. Background Technology

[0002] Powder materials are considered promising alternatives or reinforcing materials due to their wide availability, adjustable properties, potential cost advantages, and environmental benefits. In current technologies, powders are mostly used as fillers, added in small amounts to asphalt or cement matrices, or for soil stabilization, failing to fully realize their independent or dominant road application value. The technology for large-scale, highly uniform, and structurally controllable direct paving of powders into functional pavements is still immature, facing core bottlenecks such as poor paving uniformity, weak interlayer bonding, insufficient water loss resistance, and low compatibility with construction equipment, limiting the efficient and reliable application of powders in the main structural layers of highways. When plastic granules are crushed into powder and poured into the main hopper of a feeding machine, the lightweight nature of the powder makes it difficult for it to move downwards by weight, easily causing blockages and accumulations at the bottom discharge port of the main hopper. This results in slow or interrupted continuous production, leading to unnecessary economic losses. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the technical problem to be solved by this utility model is to provide a plastic powder feeding machine that can not only effectively solve the problems of slow feeding and accumulation, but also is simple to operate and easy to use.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a plastic powder feeding machine, comprising: A plastic powder feeding machine, characterized in that it comprises: Feeder mounting bracket; The main hopper is located on the top of the feeding machine mounting bracket, and the bottom of the main hopper is provided with a main discharge port; The material distribution cylinder is arranged horizontally, with the first inlet at the top and the first outlet at the bottom, and the first outlet is arranged corresponding to the first inlet. A feeding pipe is connected between the main discharge port and the first inlet of the distribution cylinder; A rotating shaft is coaxially arranged with the dispensing cylinder and rotatably disposed inside the dispensing cylinder; A rotary drive structure for driving the rotary shaft to rotate; A receiving cylinder is sleeved and fixed on the rotating shaft. The outer wall of the receiving cylinder is in close contact with the inner wall of the distributing cylinder and can roll along it. Multiple partitions are axially spaced inside the receiving cylinder, dividing the inner cavity of the receiving cylinder into multiple non-communicating receiving chambers. Multiple second inlets are axially spaced on the receiving cylinder, and each second inlet corresponds to a receiving chamber and connects the receiving chamber to the outside. When the rotating shaft rotates, the second inlets can pass sequentially below the first inlets. A stirring rod, the middle of which is hinged to the main discharge port, allows the receiving bin to sequentially move the bottom of the stirring rod to make it swing during the rotation of the rotating shaft.

[0005] Furthermore, the rotary drive structure includes a servo motor, a chain, a first sprocket, and a second sprocket. The servo motor is fixed on the feeding machine mounting bracket, the first sprocket is sleeved and fixed on the rotating shaft, the second sprocket is sleeved and fixed on the rotating shaft of the servo motor, and the chain is sleeved on the first sprocket and the second sprocket.

[0006] Furthermore, it also includes a main hopper cover plate, which is placed on the main hopper and hinged to the main hopper by a hinge member.

[0007] Furthermore, multiple hinges are provided between the main hopper cover plate and the main hopper.

[0008] Furthermore, a gas spring is provided between the main hopper cover plate and the main hopper.

[0009] Furthermore, the discharge pipe is arranged horizontally and is connected to the first discharge port. Furthermore, the blower bracket is mounted on the base plate of the feeding machine; one end of the discharge pipe is connected to the air outlet of the blower.

[0010] Furthermore, the receiving pipe is a flexible hose, which connects the discharge pipe to the first discharge port.

[0011] The beneficial effects of this utility model are: First, the feeding machine is mounted on the ground via a support bracket, with the main hopper positioned on top of the bracket. Second, a main discharge port is located at the bottom of the main hopper. The middle section of the mixing rod is hinged to the main discharge port. A rotary drive structure is used to drive the rotating shaft to rotate. A receiving cylinder is sleeved and fixed on the rotating shaft. Multiple partitions are axially spaced inside the receiving cylinder, dividing the inner cavity of the receiving cylinder into multiple non-communicating receiving chambers. Multiple second inlets are axially spaced on the receiving cylinder, and each second inlet corresponds to a receiving chamber and connects the receiving chamber to the outside. When the rotating shaft rotates, the second inlets can pass under the first inlet in sequence. During the rotation of the rotating shaft, the receiving chambers can sequentially agitate the bottom of the stirring rod, causing the stirring rod to swing back and forth, thereby agitating and vibrating the plastic powder and allowing it to fall smoothly into the next process. This ultimately solves the problem in the existing technology where, after the plastic powder is crushed into powder and put into the main hopper, the light weight of the plastic powder makes it difficult for it to enter the discharge port by its own weight.

Fourth, the chain drives the rotary drive mechanism to rotate, achieving production status. Fifth, the rotary drive mechanism drives multiple main powder hoppers to rotate, achieving production status. Sixth, the rotation of multiple main powder hoppers continuously contacts the agitators inserted into the main hoppers, causing them to oscillate back and forth, evenly agitating the plastic powder in the main hoppers. This allows the powder to fall smoothly and evenly through the feed pipe into multiple main powder hoppers. After the distribution cylinder rotates 180 degrees, the plastic powder is sent to the discharge pipe through the receiving pipe. Finally, a blower delivers the plastic powder into the production equipment.
