Description

A precise metering and feeding mechanism for a strip winding machine Technical Field

[0001] This utility model belongs to the technical field of moxa stick rolling equipment, and in particular, it is a precise metering and feeding mechanism for a moxa stick rolling machine. Background Technology

[0002] Currently, the feeding mechanism of moxa stick rolling machines on the market usually involves setting the specifications of the feeding plates of the feeding roller and controlling the number of rotations of the feeding roller for coarse feeding. After the machine has been working for a long time, the moxa sticks produced will be uneven in thickness due to blockage, material sticking, and arching of the feeding roller. Therefore, it is necessary to design a precise metering feeding mechanism to improve the uniformity of the moxa sticks. Summary of the Invention

[0003] To address the aforementioned issues, the inventors proposed a precise metering and feeding mechanism for a moxa roll machine. This mechanism primarily uses a weighing sensor to weigh and count the required moxa wool, ensuring that the weight error of the rolled moxa sticks is very small and that the weight is accurate.

[0004] To solve its technical problems, the technical solution adopted by this utility model is as follows: A precise metering and feeding mechanism for a strip winding machine is designed, characterized by including a hopper, a controller, a first motor, a second motor, and an air pump; the hopper is equipped with a leaf-pulling roller inside, and a feeding port is located at the lower end of the hopper. A large feeding roller and a small feeding roller are arranged side-by-side inside the feeding port. Both the leaf-pulling roller and the large feeding roller are driven by the first motor, and the small feeding roller is driven by the second motor; a weighing channel is provided below the feeding port of the hopper, with the weighing channel connected above and below... The material inlet is connected, and the bottom of the weighing channel is a tray with a weighing sensor installed at the bottom of the tray. The weighing sensor is electrically connected to the controller. A pusher plate is installed at the front end of the weighing channel, driven by a pusher cylinder. Above the rear section of the weighing channel, on the outside of the hopper, a pressure plate is installed, driven by a pressure cylinder. A baffle is installed at the rear end of the weighing channel, driven by a baffle cylinder. Motor 1, Motor 2, and the air pump are all electrically connected to the controller, and the pusher cylinder, pressure cylinder, and baffle cylinder are all driven by the air pump.

[0005] Furthermore, the leaf-deflecting roller consists of a roller shaft and leaf blades, and the number of leaf blades is 3-5.

[0006] Furthermore, the large feeding roller is composed of a roller shaft two and feeding blades, with 14-18 feeding blades; the small feeding roller is composed of a roller shaft three and feeding teeth, with 14-18 feeding teeth.

[0007] In use, this invention begins with the baffle lowering via a baffle cylinder to prevent material from falling onto the tray. Then, a large feeding roller, driven by motor one, rotates to feed the material, simultaneously rotating the leaf roller as well. When the material falls onto the tray, the weighing sensor begins counting. Once the set weight for the large feeding roller is reached, it stops rotating. At this point, a small feeding roller, driven by motor two, begins feeding precisely. When the cumulative weight reaches the controller's set weight, the small feeding roller stops feeding, completing the feeding process. Next, a pusher plate pushes the material under the pressure plate and holds it stationary. The pressure plate, driven by a cylinder, then presses down, lowering the material height. The baffle then lifts, and the pusher cylinder continues to drive the pusher plate, pushing the material out of the tray and into the moxa stick rolling stage.

[0008] This utility model adopts the above-mentioned technical solution. Compared with the prior art, this mechanism mainly uses a weighing sensor to weigh and count the required moxa wool, ensuring that the weight error of the rolled moxa stick is very small and the weight is accurate. Attached Figure Description

[0009] Figure 1 is a cross-sectional view of the present invention. Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments, and its structure and advantages will become clearer.

[0011] Referring to Figure 1, a precise metering and feeding mechanism for a strip winding machine includes a hopper 1, a controller, a first motor 2, a second motor 3, and an air pump. The hopper 1 is equipped with a leaf-pulling roller 4, and a feeding port is located at the lower end of the hopper 1. A large feeding roller 5 and a small feeding roller 6 are arranged side-by-side inside the feeding port. Both the leaf-pulling roller 4 and the large feeding roller 5 are driven by the first motor 2, and the small feeding roller 6 is driven by the second motor 3. A weighing channel 15 is located below the feeding port of the hopper 1, and the upper part of the weighing channel 15 communicates with the feeding port. The bottom of the weighing channel 15 is a tray 7. A weighing sensor 8 is installed at the bottom of the tray 7, and the weighing sensor 8 is electrically connected to the controller; a pusher plate 9 is installed at the front end of the weighing channel 15, and the pusher plate 9 is driven by a pusher cylinder 10; a pressure plate 11 is installed above the rear section of the weighing channel 15, located outside the hopper 1, and the pressure plate 11 is driven by a pressure cylinder 12; a baffle 13 is installed at the rear end of the weighing channel 15, and the baffle 13 is driven by a baffle cylinder 14; the motor 2, the motor 3, and the air pump are all electrically connected to the controller, and the pusher cylinder 10, the pressure cylinder 12, and the baffle cylinder 14 are all driven by the air pump.

[0012] Furthermore, the leaf-deflecting roller 4 consists of a roller shaft and leaf blades, and the number of leaf blades is 3-5.

[0013] Furthermore, the large feeding roller 5 is composed of a second roller shaft and feeding blades, with 14-18 feeding blades; the small feeding roller 6 is composed of a third roller shaft and feeding teeth, with 14-18 feeding teeth.

[0014] Under the control of the controller, the operation process of this mechanism is as follows: First, the baffle is lowered by the action of the baffle cylinder to prevent the material from falling onto the tray. Then, the large feeding roller is driven by motor one to rotate and feed the material, while also rotating the leaf roller to feed the material downwards. When the material from the large feeding roller falls onto the tray, the weighing sensor starts weighing and counting. When the set weight of the material from the large feeding roller is reached, the large feeding roller stops rotating. At this time, the small feeding roller is driven by motor two to start rotating and feeding the material, and precise replenishment begins. When the cumulative weight of the two feedings reaches the weight required by the controller, the small feeding roller stops replenishing the material, and the feeding is completed. Then, the pusher plate pushes the material under the pressure plate and keeps it stationary. Next, the pressure plate is driven by the cylinder to press down, reducing the height of the material. Then, the baffle is raised, and the pusher cylinder continues to drive the pusher plate to push the material out of the tray, entering the moxa stick rolling stage.

[0015] Although the present invention has been described in detail above, it is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many modifications under the guidance of the present invention and without departing from its spirit, and all such modifications are within the protection scope of the present invention.
