Description

Technical Field

[0001] This utility model relates to the field of operational technology, and in particular to an arch-breaking device for a ton bag unpacking machine. Background Technology

[0002] In industrial production, ton bags are widely used for packaging various materials due to their large capacity and ease of transportation and storage. However, when materials are stored for a long time or affected by factors such as compression, the materials inside the ton bags are prone to clumping and bridging, making it difficult for the materials to flow out smoothly. To solve this problem, ton bag unpacking machines have emerged, and the anti-bridging device is a key component of these machines.

[0003] Existing anti-bridging devices break up and disturb clumps of material inside ton bags using various methods to restore the material's fluidity and ensure smooth unpacking operations. Among the many anti-bridging methods, using hammers to break up bridging is a common and effective approach. However, the hammer installation method for most ton bag unpacking machines' anti-bridging devices is quite complex. Usually, the hammers are fixed to the drive shaft of the anti-bridging device by welding. But when the hammers need to be replaced, separating the welded joints is extremely difficult, often requiring the use of specialized cutting tools. This not only makes the operation cumbersome but may also damage other components of the anti-bridging device during the cutting process, leading to a significant increase in maintenance costs. This, in turn, increases the workload of the staff and reduces the maintenance and repair efficiency of the hammers. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a tungsten bag unpacking machine arch-breaking device. It can solve the problem that the hammer head is fixed on the drive shaft of the arch-breaking device by welding. However, when the hammer head needs to be replaced, the separation of the welded joint is extremely difficult. It often requires the use of professional cutting tools. Not only is the operation process cumbersome, but the cutting process may also damage other parts of the arch-breaking device, resulting in a significant increase in maintenance costs. This increases the workload of the staff and reduces the maintenance and repair efficiency of the hammer head.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tungsten bag unpacking machine with an arch-breaking device, comprising an unpacking frame;

[0006] The unpacking machine frame is equipped with two limit devices;

[0007] The limiting device includes a mounting plate, a hammer head, and two protective shells. The two protective shells are fixedly connected to each other on both sides of the hammer head. The outer walls on both sides of the mounting plate are provided with second limiting block grooves. Two T-shaped blocks are fixedly connected to the outer wall of the hammer head away from the arc surface. Two T-shaped block grooves are provided on one side of the outer wall of the mounting plate.

[0010] Among them, the ends of the two limiting blocks near the second limiting block grooves slide to the outside of the protective shell and respectively contact the inner wall of the corresponding second limiting block grooves. The ends of the two rotating threaded rods near the limiting blocks are threaded to the inside of the first limiting block grooves and respectively rotatably connected to one side of the outer wall of the corresponding limiting block.

[0031] Please see Figure 1-4 This utility model provides a technical solution: an arch-breaking device for a ton bag unpacking machine, including an unpacking machine frame 1;

[0032] Two limit devices are installed on the unpacking machine frame 1;

[0033] The limiting device includes a mounting plate 6, a hammer head 8, and two protective shells 11. The two protective shells 11 are fixedly connected to both sides of the hammer head 8. One outer wall of the hammer head 8 is arc-shaped. The outer walls of both sides of the mounting plate 6 are provided with second limiting block grooves 14. Two T-shaped blocks 15 are fixedly connected to the outer wall of the hammer head 8 away from the arc-shaped surface. Two T-shaped block grooves 7 are provided on one outer wall of the mounting plate 6. The outer walls of the two T-shaped blocks 15 are slidably connected to the interior of the corresponding T-shaped block grooves 7. The outer walls of the two protective shells 11 are provided with first limiting block grooves 13 on the outer walls of the two protective shells 11 near the hammer head 8. The interiors of the two first limiting block grooves 13 are slidably connected. With the connection of the limiting block 10, the outer wall of the two protective shells 11 near the hammer head 8 is in corresponding contact with the outer walls of the two sides of the mounting plate 6. The ends of the two limiting blocks 10 near the second limiting block groove 14 are slidably extended to the outside of the protective shell 11 and respectively contact the inner wall of the corresponding second limiting block groove 14. The outer walls of the two protective shells 11 are threadedly connected with rotating threaded rods 12. The ends of the two rotating threaded rods 12 near the limiting block 10 are threadedly extended to the inside of the first limiting block groove 13 and respectively rotatably connected to the outer wall of the corresponding limiting block 10. The two limiting devices are correspondingly set on both sides of the unpacking frame 1.

[0034] Among them, cylinders 5 are fixedly connected to the outer walls of the two fixed plates on the upper end of the unpacking machine frame 1. The output end of the cylinder 5 slides into the interior of the unpacking machine frame 1 and is fixedly connected to one side of the corresponding mounting plate 6. Two sliding rods 4 are slidably connected to the outer walls of the two fixed plates on the upper end of the unpacking machine frame 1. The four sliding rods 4 are in groups of two. The ends of the two groups of sliding rods 4 near the mounting plate 6 slide into the interior of the unpacking machine frame 1 and are fixedly connected to one side of the outer wall of the corresponding mounting plate 6. A hopper 2 is installed on the internal support frame at the lower end of the unpacking machine frame 1. A feed inlet 3 is opened on the upper surface of the hopper 2. A cutting blade 9 is installed on the inner wall of the feed inlet 3. The cutting blade 9 is triangular. A discharge pipe 16 is installed at the lower end of the hopper 2. The interior of the discharge pipe 16 is connected to the interior of the hopper 2.

[0035] Furthermore, when using this device, the ton bag is first moved above the hopper 2 and between the two hammers 8 by an external device. Then, the cylinder 5 is activated, and its output end pushes the mounting plate 6 and the hammers 8 to move horizontally along the slide rod 4. The arc-shaped hammers 8 impact the arched parts of the material in the hopper 2, breaking up the material agglomeration. Then, the external device controls the ton bag to cut and break it through the triangular cutting blade 9, allowing the material in the ton bag to enter the interior of the hopper 2 through the feed inlet 3. When the hammers 8 need to be removed, the threaded rod 12 is rotated to drive the limit block 10 to retract into the first limit block groove 13 of the protective shell 11, releasing the lock on the hammers 8. The hammers 8 can then be slid along the T-shaped block groove 7 and removed from the mounting plate 6.

[0036] By rotating the threaded rod 12 in the limiting device, the limiting block 10 is driven to retract into the first limiting block groove 13 of the protective shell 11, thereby releasing the lock on the hammer head 8. The hammer head 8 can then be slid along the T-shaped block groove 7 and removed from the mounting plate 6. This method of removing the hammer head 8 is simple and quick, effectively improving the maintenance and repair efficiency of the hammer head 8 and reducing the workload of the staff.
