Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, and in particular to an automated powder feeding device. Background Technology

[0002] Traditional Chinese medicine extraction workshops generally adopt a forklift-assisted hoisting operation mode. Specifically, operators use a forklift to move a feeding cylinder containing powdered medicinal materials to a designated location, then use an electric hoist to hoist the feeding cylinder and push it above the extraction tank. With manual assistance, the medicinal materials are tilted and poured into the extraction tank. This operation mode is labor-intensive and usually requires multiple people to work together. In addition, the medicinal dust is easily dispersed during the pouring process, and operators are exposed to the production dust environment for a long time, which poses occupational health risks. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the technical solution adopted by this utility model is: an automated powder feeding device, including a movable frame, and a moving mechanism and a feeding mechanism connected to the movable frame; the moving mechanism includes a guide rail, a moving motor, a transmission wheel and a positioning wheel, the movable frame is slidably connected to the guide rail through the transmission wheel, the movable frame is provided with a moving motor for driving the transmission wheel to rotate, and a positioning wheel for preventing derailment, the feeding mechanism includes a mounting frame, a flipping motor, a gripper and a transmission cylinder, the movable frame is rotatably connected to the mounting frame, and a flipping motor for controlling the flipping angle of the mounting frame is provided on one side of the movable frame, grippers for fixing the feeding cylinder are rotatably connected to both sides of the mounting frame, and transmission cylinders for controlling the movement of the grippers.

[0004] Using the above technical solution, the two sides of the mobile frame correspond to the aisle and the extraction tank respectively, with the gripper facing the aisle. The operator controls a forklift to move the feeding cylinder to the mounting frame. Since the gripper is rotatably connected to the mounting frame, the transmission cylinder drives the gripper to hold the feeding cylinder tightly through the lever principle. Then, the tilting motor drives the mounting frame to tilt towards the extraction tank, so that the Chinese herbal raw materials in the feeding cylinder are poured into the extraction tank, avoiding material spillage. This feeding device abandons the traditional manual handling and lifting feeding mode, greatly reduces the labor intensity, improves the automation level and operating efficiency of the production line, and avoids the operator directly contacting the dust generated when the raw materials are put into the extraction tank, protecting the operator's personal safety.

[0005] The present invention is further configured such that the movable frame includes an upper crossbeam, a lower crossbeam, columns, a positioning plate, and a connecting piece; columns are fixedly connected to both sides of the lower crossbeam; the upper crossbeam is fixedly connected to the lower crossbeam through the columns; the mounting frame is rotatably connected between the two sets of columns; and the flipping motor is fixedly connected to the outer side of the columns; and the connecting piece is connected to both ends of the lower crossbeam through the positioning plate.

[0006] Furthermore, the two sets of positioning plates are distributed in parallel between the lower crossbeam and the adapter, the transmission wheel is rotatably connected between the two sets of positioning plates, and the output end of the moving motor is provided with a reducer connected to the transmission wheel. The moving motor is fixedly connected to the outside of the positioning plate through the reducer.

[0007] Using the above technical solution, the mobile frame adopts a rectangular frame structure formed by four sets of square steel. Two sets of positioning plates provide rotation fulcrums for the transmission wheels, so that the mobile frame can move laterally along the guide rail. The mobile motor is installed on the side of the mobile frame facing the aisle, avoiding increasing the thickness of the mobile frame and preventing interference with the aisle area or extraction tank area, thus optimizing space utilization.

[0008] The present invention is further configured such that the adapter includes an inner plate, an outer plate, a bottom plate and a reinforcing plate, the inner plate and the outer plate are vertically distributed on the left and right sides of the bottom plate, and a reinforcing plate is provided between the inner plate, the outer plate and the bottom plate, the inner plate is fixedly connected between the two sets of positioning plates, and the positioning wheel is rotatably connected to the front and rear sides of the bottom plate.

[0009] Furthermore, the upper crossbeam has top plates at both ends, and the bottom of the top plates has triangular ribs connected to the upper crossbeam. The positioning wheels are rotatably connected to both sides of the top plates.

[0010] Using the above technical solution, the adapter is arranged in an I-shape. The upper and lower crossbeams are rotatably connected to positioning wheels through the top and bottom plates, respectively. The positioning wheels prevent the moving frame from tilting and effectively prevent derailment.

[0011] The present invention is further configured such that the guide rail includes an upper guide rail and a lower guide rail, the transmission wheel is rotatably connected to the lower guide rail, and the upper and lower sides of the movable frame are provided with positioning wheels that are perpendicular to the transmission wheel, the positioning wheels being located on both sides of the upper / lower guide rail.

[0012] Furthermore, the upper guide rail is made of square steel, the lower guide rail is made of I-beam, the transmission wheel is rotatably connected to the top surface of the I-beam, and the positioning wheel is rotatably connected to both sides of the square steel / I-beam.

[0013] Using the above technical solution, the square steel and the I-beam form a double track structure that is parallel to each other. The drive wheel is rolled and connected to the top surface of the I-beam to provide effective support for the moving frame. The positioning wheels are distributed on the front and rear sides of the square steel and the I-beam to prevent the moving frame from tilting and derailing. This solution is suitable for the complex working conditions of heavy load and overturning of Chinese medicine raw materials during the feeding process.

[0014] The present invention is further configured such that a photoelectric sensor is provided on one side of the upper crossbeam.

[0015] By adopting the above technical solution, non-contact positioning of the moving frame is achieved through photoelectric sensors, thereby improving feeding accuracy and meeting the requirements of automated feeding.

[0016] The present invention is further provided that buffer blocks are provided at both ends of the lower guide rail.

[0017] The above technical solution is adopted, and mechanical limit buffer blocks are installed at both ends of the lower guide rail. As a protective structure, when the control system causes the moving frame to exceed the preset travel range due to signal interference or program abnormality, the buffer block forcibly intercepts the moving frame to prevent the moving frame from rushing out of the guide rail and causing equipment damage or safety accidents.
