Description

Technical Field

[0001] The utility model belongs to the field of plastic particle dosing devices, in particular to a plastic particle dosing device with controllable constant speed. Background Art

[0002] A plastic pellet dosing system is primarily a material conveying system used in industrial production, transporting plastic pellets from one location to another. It typically consists of a conveyor belt, conveyor, motor, and control system. Over the past few decades, with the continuous advancement of industrial automation and intelligentization, plastic pellet dosing systems have also experienced significant development. Traditional manual dosing methods have been gradually replaced by automated equipment such as automatic metering and dosing systems, electronic weighing and dosing systems, and laser measurement and dosing systems. Modern plastic pellet dosing systems utilize a wide range of advanced technologies, such as microelectronics, computer control, communications, and sensors. These technologies enable more accurate, stable, and controllable dosing of plastic pellets, significantly improving production efficiency and product quality.

[0003] An existing discharging device for plastic particles (e.g., application number: CN207808141U) generally has the following problems during use:

[0004] 1. Unable to control the dosing speed of plastic pellets: Decreased production quality: If the dosing speed of plastic pellets cannot be controlled, it may lead to uneven or too fast dosing, resulting in unstable product quality or even quality defects. Energy waste: Too fast a dosing speed may lead to energy waste, because the energy consumed by the system will increase when running at high speed, thereby increasing production costs. Raw material waste: Unable to control the dosing speed may also lead to excessive dosing, resulting in waste of raw materials, increased production costs, and unnecessary impact on the environment. Equipment damage: Excessive dosing speed may cause damage to the equipment, shorten the service life of the equipment, increase maintenance and replacement costs, so there is an urgent need for a controllable and constant speed plastic pellet dosing device.

[0005] 2. The height of the dosing device cannot be adjusted, and the scope of application is limited: Limited scope of application: If the height of the dosing device cannot be adjusted, then it can only be applied to production lines or equipment of a specific size or shape. This will limit its flexibility and versatility, making it unable to adapt to production needs of different specifications and requirements. Decreased production efficiency: In some cases, the need to replace the production line or equipment to adapt to the fixed height of the dosing device will increase the downtime and adjustment time of the production line, thereby reducing production efficiency. Increased costs: Since the height of the dosing device cannot be flexibly adjusted, additional customized design or purchase of multiple dosing devices of different heights may be required, which will increase equipment procurement costs and maintenance costs. Waste of resources: If the height of the dosing device cannot be adjusted, it may lead to excessive or insufficient dosing, resulting in waste of raw materials or product quality problems, increasing production costs, so there is an urgent need for a plastic particle dosing device with adjustable height.

[0006] 3. Unable to know the remaining number of pellets in the pellet hopper: Production pause: If the remaining number of pellets in the pellet hopper cannot be accurately known, the pellets may run out, causing the production line to pause, resulting in production delays and losses. Waste of resources: Conversely, if the remaining number of pellets cannot be accurately known, in order to avoid pauses caused by the exhaustion of pellets, operators may over-feed the pellets, resulting in waste of resources and increased production costs. Product quality issues: The inability to know the remaining number of pellets may lead to uneven pellet delivery, thereby affecting the quality stability and consistency of the product. Therefore, there is an urgent need for a plastic pellet dosing device that can know the remaining amount of plastic pellets in the holding hopper. Utility Model Content

[0029] The operating process of this utility model:

[0030] This controllable, constant-speed plastic pellet dosing device is an electrically controlled device. First, the plastic pellets to be processed are placed in a plastic pellet hopper 1. The pellet depth sensor 10 controls the pellet delivery rate. Then, when processing is required, the discharge of the plastic pellets is controlled by opening the discharge door and switching on the switch 12. The discharge door's sliding track 13 ensures smooth movement. A pellet conveyor belt 3 at the lower end of the discharge door delivers the plastic pellets to the equipment for processing.
