Technical Field

[0001] The present application relates to the field of fireworks production equipment, and particularly to a medicine mixing device. Background Art

[0002] Since the inner diameter of a single paper tube of fireworks is relatively large and the amount of gunpowder filled is required to be relatively accurate, the traditional manual gunpowder filling method has been used for filling gunpowder in fireworks in the prior art, which is slow, inefficient, requires a large number of operators and is unsafe. There is an urgent need for an automated fireworks filling mechanical production line to replace manual operation. Summary of the Invention

[0003] To achieve the above object, a medicine mixing device is proposed in the present application, including:

[0004] A base;

[0005] A medicine mixing mechanism is arranged on the base, a belt conveying mechanism is arranged on the medicine mixing mechanism, and a pressing mechanism is arranged on the belt conveying mechanism; a power mechanism is arranged at the far ends of the belt conveying mechanism and the medicine mixing mechanism, and the power mechanism is configured to provide power for the belt conveying mechanism and the medicine mixing mechanism; the power mechanism is connected to the belt conveying mechanism through a transmission shaft with small rigidity and free bendability.

[0006] Through the above technical solution, the power mechanism is connected to the belt conveying mechanism through a transmission shaft with small rigidity and free bendability, which can adapt to different installation positions and spatial layouts, and reduces vibration and noise during power transmission.

[0007] Specifically, it further includes: a sensor and a blocking cylinder; the sensor is arranged at one end of the belt conveying line and is configured to detect the position and quantity of gunpowder cake on the belt conveying line; the blocking cylinder is arranged at one end of the pressing mechanism and on the same side as the sensor; the blocking cylinder responds to the detection signal of the sensor, and the cylinder descends to block the gunpowder cake.

[0008] Through the above technical solution, the sensor can accurately detect the position and quantity of the gunpowder cake on the belt conveying line, providing accurate data for subsequent control; the blocking cylinder responds to the detection signal of the sensor, and the cylinder descends to block the gunpowder cake, which can achieve precise positioning and control of the gunpowder cake, facilitating subsequent medicine mixing operations or other treatments.

[0009] Specifically, the belt conveying mechanism includes a flat belt, a first bearing seat, a tensioning seat, a rigid coupling, a second bearing seat and a transmission shaft; the tensioning seat and the first bearing seat are mounted on the medicine mixing mechanism, and both the tensioning seat and the first bearing seat are installed with a roller shaft; the second bearing seat is connected to the first bearing seat through the transmission shaft and the rigid coupling, and the power of the power mechanism is transmitted to the roller shaft arranged between the first bearing seats through the transmission shaft and the rigid coupling, thereby driving the flat belt to move.

[0010] Through the above technical solution, the tensioning seat can adjust the tension of the flat belt, ensuring that the belt does not slip during operation, and improving the efficiency and stability of belt conveying.

[0011] Specifically, it further includes: a water tank; the water tank is installed above the base; the water tank is provided with a drain port, and a ball valve is installed below the drain port.

[0012] Through the above technical solution, a certain amount of water is stored in the water tank, and the gunpowder powder generated during the operation of the medicine mixing mechanism falls into the water in the water tank, thereby isolating and wetting the gunpowder from the air and hindering its flammability.

[0013] Specifically, the medicine mixing mechanism includes: side plates, the driving shaft and the driven shaft are rotatably arranged at both ends of the side plates and are at the same horizontal height. Synchronous wheels are respectively arranged at the same ends of the driving shaft and the driven shaft. A synchronous belt is sleeved on the synchronous wheels, and the pre-tightening force of the synchronous belt is adjusted by a tensioning mechanism fixed on the side wall of the water tank.

[0014] Specifically, the medicine mixing mechanism further includes: a bearing sleeved above the driving shaft, and an eccentric wheel arranged below the driving shaft; and the medicine mixing mechanism makes a circular motion under the action of the eccentric wheel.

[0015] The tensioning mechanism can adjust the pre-tightening force of the synchronous belt, ensuring that the synchronous belt does not slack during operation and improving the transmission efficiency.

[0016] Specifically, a detection block and a sensor are arranged between the driving shaft and the lower end surface of the belt conveying mechanism.

[0017] The arrangement of the detection block and the sensor can detect the position of the driving shaft, provide feedback information for the operation of the medicine mixing device, facilitate the precise control of the belt height, and ensure the smooth passing of the gun cake during loading and unloading.

[0018] Specifically, the power mechanism and the medicine mixing mechanism are connected by a rigid transmission shaft.

[0019] Specifically, the transmission shaft with small rigidity and free bending includes: a flexible shaft and an elastic coupling.

[0020] Compared with the prior art, the advantages of this application are as follows:

[0021] (1) The base is designed with a water tank and stores a certain amount of water. The gunpowder powder generated during the operation of the medicine mixing mechanism falls into the water in the water tank, thereby isolating and wetting the gunpowder from the air and hindering its flammability;

[0022] (2) The medicine mixing mechanism is an eccentric wheel mechanism, which makes the gun cake do a circular motion, and under the action of centrifugal force, the medicine powder in the gun cake is evenly mixed;

[0023] (3) The power mechanism is divided into the power of the belt conveyor line and the power of mixing medicine. Among them, the power transmission between the belt conveyor line and the motor adopts a flexible shaft drive, effectively solving the problem that the relative positions of the motor shaft and the belt conveyor drum shaft are constantly changing.

[0024] (4) The conveying unit adopts belt conveying to connect the bubble cakes of the incoming material conveying line and the blanking conveying line, ensuring the fully automated operation of the entire equipment.

[0025] (5) When the equipment stops mixing medicine, two control methods, namely sensors or encoders, are used to control the position of the equipment transmission shaft, and further control the accuracy of the belt height when mixing medicine stops. Description of the Drawings
