Technical Field
[0001] This utility model relates to the field of unpacking machine technology, specifically a dustproof unpacking machine. Background Technology
[0002] The copper powder-specific ton bag unpacking machine is an automated device used for efficient and dust-free unpacking of large-capacity ton bags. It uses lifting, cutting, vibration or tapping mechanisms to accurately unload copper powder from the ton bag onto the conveyor belt, ensuring continuous material transport and effectively controlling dust spillage.
[0003] Existing technology, such as the patent application "CN221091612U", relates to the field of unpacking machine technology and discloses a ton bag unpacking machine, including a body, a support base, and a slide rail. The support base is installed below the body of the unpacking machine, and the slide rail is installed on the upper right side of the body. An electric hoist is installed on the lower right side of the slide rail, and a fixing plate is installed below the electric hoist. The support plate is installed inside the body of the unpacking machine, and a discharge port is located in the middle of the support plate. A sliding device is installed below the support plate and is located at the bottom of the body of the unpacking machine. The sliding device includes a fixing base, a storage tank, and a sliding column. The fixing base is installed at the bottom of the body of the unpacking machine, and the storage tank contains the sliding column. This patent aims to quickly empty the material from the ton bag, preventing blockage and improving the working efficiency of the device.
[0004] However, current ton bag unpacking machines have several problems: existing machines generally have an opening at the top for the electric hoist to enter, which results in significant dust being blown out during material unpacking and pouring. Furthermore, the machine's door is opened and closed using an electric push rod, which requires regular maintenance, increasing equipment costs. Therefore, we propose a dustproof unpacking machine.

[0011] By employing the above technical solution, this utility model provides a dustproof unpacking machine. Its beneficial effects are as follows: Through the inclined lower buckle plate and rubber strip, the dust stirred up by the unpacking machine after disassembling the material bag is blocked by the inclined lower buckle plate. The rubber strip, utilizing its flexibility, adheres to the rope of the electric hoist, sealing the top opening of the unpacking machine. Furthermore, through a series of mechanical transmissions, there is no need to use electric push rods or other closing components to respond to the closing of the aluminum alloy door, completely eliminating the need for the traditional electric push rod device. This not only reduces the periodic maintenance costs required due to electric push rod failures but also, through the double sealing design of the inclined lower buckle plate and flexible rubber strip, effectively prevents dust from escaping from the top opening. This fundamentally solves the problems of dust leakage and reliance on high-maintenance electric components in existing equipment, achieving a lower-cost, more airtight, and environmentally friendly unpacking operation.

The sealing device 2 includes a lower buckle plate 21 and a rubber strip 22. The lower buckle plate 21 is fixedly installed on the inner wall opposite the notch at the top of the packaging machine body 1, and the rubber strip 22 is fixedly installed on the outer wall opposite the lower buckle plate 21.
[0020] There are two lower buckle plates 21 and rubber strips 22, and the lower buckle plates 21 and rubber strips 22 are set at an angle to each other, and the rubber strips 22 are made of flexible rubber.
[0021] The sealing device 2 also includes a hinge block 23, a rotating rod 24, an aluminum alloy door 25, a rotating shaft 26, a rotating column 27, a rotating shell 28, a push rod 1 29, a push rod 210, a torsion spring 211, a rack 212, and an L-shaped abutment rod 213. The hinge block 23 is fixedly installed on the outer wall of the front of the unpacking machine body 1. The rotating rod 24 passes through and is rotatably installed on the top of the hinge block 23. The aluminum alloy door 25 is fixedly installed on the outer wall of the rotating rod 24. The rotating shaft 26 is rotatably installed on the top of the unpacking machine body 1 near the I-beam slide rail 11. The rotating column 27 is fixedly installed on the rotating shaft 26. At the top, the rotating shell 28 is fixedly installed on the outer wall of the rotating shaft 26, the push rod 1 29 is fixedly installed on the outer wall of the rotating shell 28 near the rubber strip 22, the push rod 210 is fixedly installed on the outer wall of the rotating shell 28 away from the rubber strip 22, the torsion spring 211 is set between the rotating shell 28 and the top surface of the unpacking machine body 1, one end of the rack 212 is rotatably installed on the outer wall of the rotating column 27, and the other end of the rack 212 is rotatably installed on the top outer wall of the rotating rod 24, and the L-shaped stop rod 213 is fixedly installed on the outer wall of the electric hoist 12 near the unpacking machine body 1.
[0022] There are two sealing devices 2. The top outer wall of the rotating rod 24 is provided with toothed blocks, the bottom outer wall of the rotating column 27 is provided with toothed blocks, the push rods 29 on both sides are arranged vertically and horizontally, the inner wall of the rack 212 is provided with toothed grooves, and the toothed grooves of the rack 212 mesh with the toothed blocks of the rotating rod 24 and the rotating column 27 respectively. The rack 212 is installed through and rotatably on the outer wall of the top support column of the unpacking machine body 1, and the L-shaped abutment 213 is located on the movement trajectory of the push rod 29.
[0023] In use, the dustproof unpacking machine of this utility model places the material bag on the lifting head 13, and turns on the electric hoist 12.

After unpacking, the electric hoist 12 slides outwards, and the rotating housing 28, subjected to the torque of the torsion spring 211, along with the contact between the electric hoist 12's rope and the push rod 210, causes the rotating column 27 to... The moving rack 212 rolls in the opposite direction, thereby opening the aluminum alloy door 25. Through the setting of the inclined lower buckle plate 21 and the rubber strip 22, the dust kicked up by the material bag after the unpacking machine removes the material bag is blocked by the inclined lower buckle plate 21, while the rubber strip 22, with its flexible properties, will adhere to the rope of the electric hoist 12 to complete the sealing of the top opening of the unpacking machine body 1. Through a series of mechanical transmissions, there is no need to use closing components such as electric push rods to respond to the closing of the aluminum alloy door 25, completely eliminating the opening and closing of the traditional electric push rod device. This not only reduces the periodic maintenance costs required due to electric push rod failure, but also, through the double sealing design of the inclined lower buckle plate 21 and the flexible rubber strip 22, effectively prevents dust from escaping from the top opening. This fundamentally solves the problems of dust leakage and reliance on high-maintenance electric components in existing equipment, and achieves environmentally friendly unpacking operations with lower cost and higher sealing performance.
