Description

Technical Field

[0001] This utility model belongs to the technical field of feeding equipment, specifically relating to an automatic solid feeding machine. Background Technology

[0002] Dust-free feeding stations are used for unpacking, feeding, screening, and unloading small-bag materials in the food, pharmaceutical, chemical, and metallurgical industries. They are particularly suitable for manual feeding and pre-screening of powders. During unpacking, the dust collection fan prevents material dust from flying everywhere. Dust-free feeding stations are suitable for feeding powders from ovens, freeze-dried raw materials, materials in bags of various sizes, and drums. They are simple and convenient to operate, cost-effective, and have built-in dust collection.

[0003] When using a small dust-free feeding machine, materials are generally fed manually. Although the dust-free feeding machine can avoid generating dust during feeding, the manual up-and-down handling is very laborious. However, using a top-mounted hoist for lifting requires specific site conditions, so improvements are needed to reduce the amount of manual handling and increase efficiency. Utility Model Content

A cabinet door 21 is hinged at the top of the opening of the sealing cover 2. A blower and back-blowing device 22 extends inwards through the top of the sealing cover 2. A discharge port 11 is located at the top of the frame 1 corresponding to the interior of the sealing cover 2. A direct-discharge screening device 24 is located below the discharge port 1 on the frame 1. Multiple side frames 26 are installed along the sides of the direct-discharge screening device 24, which is mounted on a baffle in the middle of the frame 1 via the side frames 26. An extension plate 31 is located on the front of the frame 1. Connecting plates 32, which connect to the frame 1, are installed on both the top and bottom sides of the extension plate 31. 31 is installed on the front side of the frame 1 via a connecting plate 32 and is fixed by bolts. A slot is opened at the mounting location of the connecting plate 32 on the frame 1 so that the height of the connecting plate 32 and the bolt is flush with the height of the top surface of the frame 1. Sliding rods 33 are slidably inserted on both sides of the extension plate 31. The sliding rods 33 and the extension plate 31 are connected by a sliding sleeve. A pressure plate 34 is fixedly inserted at the top of the two sliding rods 33. A feeding roller 35 is horizontally arranged in the middle of the pressure plate 34. The bottom of the feeding roller 35 passes through the pressure plate 34. A motor 36 is arranged on the top of one side of the pressure plate 34. The output end of the motor 36 is connected to the feeding roller 35 by gear transmission. An auxiliary feeding structure is provided on the front side of the frame 1.

[0017] The sealing cover 2 is equipped with hydraulic rods 23 on both sides of the cabinet door 21 for easy opening. The surface of the discharge port 11 is equipped with a protective net 12 to prevent the plastic bag from falling directly into the discharge port 11.

[0018] A small vibrator 25 is installed on one side of the direct discharge screening equipment 24. The direct discharge screening equipment 24 is connected to the top discharge port 11 by a hose and a strap. The small vibrator 25 can shake off the material blocking the discharge port 11.

[0019] The surface of the slide rod 33 has an external thread 37 corresponding to the section connected to the sliding sleeve. A nut 38 is threadedly connected to the external thread 37. The external thread 37 on the surface of the slide rod 33 can be used to adjust the position of the slide rod 33 in the upper and lower parts of the sliding sleeve. The nut 38 is used to limit the position. According to the height of different materials, the height difference between the feeding plate 47 and the bottom extension plate 31 can be adjusted, so that the material is pushed more appropriately.

[0020] The auxiliary feeding structure includes a base 41 and a scissor arm 44. The bottom side of the scissor arm 44 is rotatably mounted on one side of the base 41, and the other side of the bottom of the scissor arm 44 is laterally connected to a crossbar 48.

A hydraulic push rod 45 is provided on the rear side of the sleeve 49. A top plate 46 is provided at the rear end of the hydraulic push rod 45. The top plate 46 is laterally fixed inside the base 41.

[0021] Working principle: The worker takes one bag from the material pile on one side of the vehicle or stacks it on the flat feeding plate 47. Then, the worker activates the hydraulic push rod 45 at the bottom, which is connected to the crossbar 48 through the output sleeve 49. The two sides of the crossbar 48 are connected to the bottom side of the scissor arm 44, thereby pushing the scissor arm 44 to rise and lift the feeding plate 47. After the material is transported upward and level with the extension plate 31, the worker only needs to flip or move the material to the bottom of the pressure plate 34. Before that, the position of the sliding rod 33 can be adjusted by adjusting the position of the sliding rod 33 on the sliding sleeve surface. When the sliding rod 33 moves upward, the nut 38 rotates downward, and when the sliding rod 33 moves downward, the nut 38 rotates upward. This allows the pressure plate 34 and the feeding roller 35 to make better contact with the material, thus pushing the material forward to the top of the discharge port 11.
