Abstract

The present application belongs to the technical field of industrial processing equipment, and particularly relates to a device and process for extruding and loosening agglomerated powder or sheet bagged materials. A servo motor is installed in the interior of a driving sprocket, the servo motor drives the driving sprocket to rotate, so that the roller can rotate synchronously with the conveying belt, reducing the sliding friction between the bagged materials and the conveying belt. Under the action of four sets of rectangular springs, the downward pressure is uniform, and the downward pressure can be increased or decreased according to the demand by adjusting the length of the guide shaft. The roller is always kept in close contact with the upper surface of the bagged materials, ensuring that there is enough downward pressure to extrude and scatter the materials. The connecting rod support frame ensures that the sprocket is always in a tensioned state, ensuring normal rotation of the sprocket. The problem of tooth skipping caused by the change in the length of the chain when the sprocket moves up and down is solved. Without the use of precision equipment, the extrusion and loosening of agglomerated powder or sheet bagged materials are well achieved through the cooperation of various mechanisms.

Description

Technical Field

[0001] This invention belongs to the field of industrial processing equipment technology, specifically a device for squeezing and loosening clumps of powdery or flaky bagged materials. Background Technology

[0002] Currently, many auxiliary materials used in the metallurgical industry are in powder or flake form, such as sodium hydroxide. Many of these materials tend to clump together in humid environments. If they are not squeezed and loosened before use, their reaction effect may be weakened.

[0003] The current mainstream solution is to manually pat or drop the packaging materials to loosen them. However, this method is labor-intensive and the force cannot be guaranteed. Excessive force may cause the packaging to break and the material to leak, while insufficient force will not loosen the central part of the material, resulting in poor effectiveness. Another method is to use external equipment to loosen the materials, but most of these methods are too complex or require precision equipment for accurate control to accommodate different sizes of bagged materials. These technologies increase the number of processes, and the precision equipment cannot adapt well to the harsh working environment, leading to a significant increase in production costs. They also cannot be well integrated with upstream and downstream workstations. To solve the above problems, a device for squeezing and loosening clumps of powdery or flaky bagged materials is proposed. Summary of the Invention

[0004] To address the problems existing in the prior art, the main objective of this invention is to propose a device and process for loosening clumps of powdery or flaky bagged materials. This solves the problem that manually patting or dropping the materials in the packaging to loosen them is laborious and the force cannot be guaranteed.

[0005] To address the aforementioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution:

[0006] An apparatus for compressing and loosening clumps of powdery or flaky bagged materials, comprising:

[0007] A roller for compressing bagged materials and a drive chain installed on one side of the roller. Both ends of the roller are equipped with brackets, and the top of the brackets is provided with sliders. The two ends of the roller are rotatably connected to the inside of the sliders, and the top of the sliders is provided with rectangular springs. The surface of the roller is provided with multiple semi-cylindrical pressure strips.

[0008] As a preferred embodiment of the device for compressing and loosening agglomerated powdery or flaky bagged materials according to the present invention, wherein: a plurality of the semi-cylindrical pressure strips are staggered along the direction parallel to the axis of the roller.

[0009] As a preferred embodiment of the device for compressing and loosening agglomerated powdery or flaky bagged materials according to the present invention, wherein: there is more than one semi-cylindrical pressure strip on the same axial length direction on the outer surface of the roller.

[0010] As a preferred embodiment of the device for compressing and loosening agglomerated powdery or flaky bagged materials according to the present invention, wherein: the top of the support is threadedly connected to a guide shaft, and the slider and the rectangular spring are both movably sleeved on the outer surface of the guide shaft.

[0011] As a preferred embodiment of the device for compressing and loosening agglomerated powdery or flaky bagged materials according to the present invention, the bagged materials are conveyed by a conveyor belt and the compressed and loosened between the conveyor belt and the rollers.

[0012] As a preferred embodiment of the device for compressing and loosening agglomerated powdery or flaky bagged materials according to the present invention, wherein: a driven sprocket is fixedly installed at the end of the roller, the top end of the transmission chain is installed on the outer surface of the driven sprocket, and a driving sprocket is installed inside the bottom end of the transmission chain.

[0013] As a preferred embodiment of the device for compressing and loosening agglomerated powdery or flaky bagged materials according to the present invention, wherein: a guide groove plate is fixedly installed at the bottom of the support, and a chain guide ring is slidably connected inside the guide groove plate, and the chain guide ring abuts against the inner side of the driven sprocket.

[0014] As a preferred embodiment of the device for compressing and loosening agglomerated powdery or flaky bagged materials according to the present invention, wherein: a connecting rod support is installed on the outer surface of the chain guide ring, and a circular spring for spreading the transmission chain is installed on the lower middle surface of the connecting rod support.

[0015] As a preferred embodiment of the device for compressing and loosening agglomerated powdery or flaky bagged materials according to the present invention, wherein: a drag rod is fixedly installed on the side of the guide groove plate, a circular spring is movably sleeved on the upper outer surface of the drag rod, and the drag rod passes through the middle of the top of the connecting rod support.

[0016] To solve the above-mentioned technical problems, according to another aspect of the present invention, the present invention provides the following technical solution:

[0017] A process for loosening clumps of powdery or flaky bagged materials, comprising:

[0018] The above device is installed on the conveyor belt. The drive sprocket and transmission chain transmit torque to the roller to rotate in the direction of the bagged material. When the bagged material moves under the roller and slowly passes through, the roller is slowly lifted up, compressing the length of the rectangular spring. At the same time, the driven sprocket also moves upward, driving the transmission chain to be further tensioned. The semi-circular pressure strip on the roller provides a forward thrust to the bagged material when it rotates. After the bagged material has completely passed through, the connecting rod support pushes the tensioning sprocket to both sides, restoring the device to its initial state.

[0019] The beneficial effects of this invention are as follows:

[0020] This invention proposes a device for compressing and loosening clumps of powdery or flaky bagged materials. A servo motor is installed inside the drive sprocket, which drives the drive sprocket to rotate. This allows the roller to rotate synchronously with the conveyor belt, reducing sliding friction between the bagged material and the conveyor belt. The semi-circular pressure strips on the roller provide forward thrust to the bagged material during rotation, preventing slippage and enhancing the compression and loosening effect. Four sets of rectangular springs ensure uniform downward pressure, and the downward pressure can be increased or decreased as needed by adjusting the guide shaft length to accommodate different sizes of bagged materials. The roller always remains firmly pressed against the upper surface of the bagged material, ensuring sufficient downward pressure to compress and disperse the material. A connecting rod support ensures the sprocket remains taut, guaranteeing normal rotation and solving the problem of skipped teeth caused by chain length changes during sprocket movement. Without requiring precision equipment, the device effectively compresses and loosens clumps of powdery or flaky bagged materials through the coordinated operation of various mechanisms.

[0027] The technical solutions described below in conjunction with the embodiments will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] This invention proposes a device for squeezing and loosening clumps of powdery or flaky bagged materials, which solves the problem that manually patting or dropping the materials in the packaging to loosen them is laborious and the force cannot be guaranteed.

[0029] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0030] One embodiment of the present invention discloses an apparatus for loosening clumps of powdery or flake-shaped bagged materials.

[0031] According to the appendix Figure 1-3 As shown, it includes a roller 13 for squeezing bagged materials and a transmission chain 10 installed on one side of the roller 13. Both ends of the roller 13 are equipped with brackets 3, and the top of the brackets 3 is provided with a slider 12. The two ends of the roller 13 are rotatably connected to the inside of the slider 12. The top of the slider 12 is provided with a rectangular spring 2. The surface of the roller 13 is provided with a plurality of semi-cylindrical pressure strips.

[0032] Furthermore, the top of the bracket 3 is threadedly connected to a guide shaft 1, and the slider 12 and the rectangular spring 2 are all movably sleeved on the outer surface of the guide shaft 1.

[0033] The bagged material 4 is conveyed by a conveyor belt and then squeezed and loosened between the conveyor belt and the roller 13.

[0034] A driven sprocket 14 is fixedly installed at the end of the roller 13, the top of the transmission chain 10 is installed on the outer surface of the driven sprocket 14, and a drive sprocket 11 is installed inside the bottom end of the transmission chain 10.

[0035] Furthermore, a guide plate 6 is fixedly installed at the bottom of the support. A chain guide ring 9 is slidably connected inside the guide plate 6. The chain guide ring 9 abuts against the inner side of the driven sprocket 14. A connecting rod support 7 is installed on the outer surface of the chain guide ring 9. A circular spring 5 for spreading the transmission chain 10 is installed on the lower surface of the middle part of the connecting rod support 7. A drag rod 8 is fixedly installed on the side of the guide plate 6. A circular spring 5 is movably sleeved on the upper outer surface of the drag rod 8. The drag rod 8 passes through the middle of the top of the connecting rod support 7. During the operation of this device, the circular spring 5 always presses the middle part of the connecting rod support 7 downwards, so that the bottom of the connecting rod support 7 maintains a tendency to spread out to both sides. At this time, when the bagged material 4 passes under the roller 13, the slider 12 moves up and down, and the transmission chain 10 is spread out to both sides by the two sets of chain guide rings 9, so as to prevent the transmission chain 10 from becoming loose and skipping teeth.

[0036] When in use, this device is mounted on a conveyor belt (to highlight the specific structure of the device that crushes and loosens clumps of powdery or flaky bagged materials). Figure 1-3 On the conveyor belt (not shown), a servo motor is installed inside the drive sprocket 11, which drives the drive sprocket 11 to rotate. The drive sprocket 11 then drives the driven sprocket 14 to rotate via the transmission chain 10. The driven sprocket 14 drives the roller 13 to rotate, allowing the roller 13 to rotate synchronously with the conveyor belt. This reduces the sliding friction between the bagged material 4 and the conveyor belt. The semi-circular pressure strip on the roller 13 provides a forward thrust to the bagged material 4 during rotation, ensuring the material does not slip and enhancing the compression and loosening effect, making it easier to compress the material into a loose state. Simultaneously, under the action of four sets of rectangular springs 2, the roller 13 always remains firmly pressed against the upper surface of the bagged material 4, ensuring sufficient pressure. The downward pressure is used to squeeze and break up the material. The compression of the rectangular spring 2 can be adjusted by rotating the guide shaft 1 to ensure uniform downward pressure. The downward pressure can also be increased or decreased as needed by adjusting the length of the guide shaft 1 to accommodate different sizes of bagged materials 4. The roller 13 always keeps it tightly pressed against the upper surface of the bagged material 4 to ensure sufficient downward pressure to squeeze and break up the material. The connecting rod support 7 ensures that the sprocket is always kept taut and rotates normally. This solves the problem of tooth skipping that may be caused by changes in the length of the transmission chain 10 when the sprocket moves up and down. Without the need for precision equipment, the various mechanisms work together to effectively squeeze and loosen clumps of powdery or flaky bagged materials.

[0037] Another embodiment of the present invention discloses an apparatus for loosening clumps of powdery or flake-shaped bagged materials.

[0038] According to the appendix Figure 1-3As shown, it includes a roller 13 for squeezing bagged materials and a transmission chain 10 installed on one side of the roller 13. Both ends of the roller 13 are equipped with brackets 3, and the top of the brackets 3 is provided with a slider 12. The two ends of the roller 13 are rotatably connected to the inside of the slider 12. The top of the slider 12 is provided with a rectangular spring 2. The surface of the roller 13 is provided with a plurality of semi-cylindrical pressure strips.

[0039] Furthermore, the plurality of the semi-cylindrical pressure strips are staggered along the axis parallel to the roller 13; and there is more than one semi-cylindrical pressure strip on the same axial length direction on the outer surface of the roller 13.

[0040] Furthermore, the top of the bracket 3 is threadedly connected to a guide shaft 1, and the slider 12 and the rectangular spring 2 are all movably sleeved on the outer surface of the guide shaft 1.

[0041] The bagged material 4 is conveyed by a conveyor belt and then squeezed and loosened between the conveyor belt and the roller 13.

[0042] A driven sprocket 14 is fixedly installed at the end of the roller 13, the top of the transmission chain 10 is installed on the outer surface of the driven sprocket 14, and a drive sprocket 11 is installed inside the bottom end of the transmission chain 10.

[0043] Furthermore, a guide plate 6 is fixedly installed at the bottom of the support. A chain guide ring 9 is slidably connected inside the guide plate 6. The chain guide ring 9 abuts against the inner side of the driven sprocket 14. A connecting rod support 7 is installed on the outer surface of the chain guide ring 9. A circular spring 5 for spreading the transmission chain 10 is installed on the lower surface of the middle part of the connecting rod support 7. A drag rod 8 is fixedly installed on the side of the guide plate 6. A circular spring 5 is movably sleeved on the upper outer surface of the drag rod 8. The drag rod 8 passes through the middle of the top of the connecting rod support 7. During the operation of this device, the circular spring 5 always presses the middle part of the connecting rod support 7 downwards, so that the bottom of the connecting rod support 7 maintains a tendency to spread out to both sides. At this time, when the bagged material 4 passes under the roller 13, the slider 12 moves up and down, and the transmission chain 10 is spread out to both sides by the two sets of chain guide rings 9, so as to prevent the transmission chain 10 from becoming loose and skipping teeth.

[0044] When in use, this device is mounted on a conveyor belt (to highlight the specific structure of the device that crushes and loosens clumps of powdery or flaky bagged materials). Figure 1-3On the conveyor belt (not shown), the transmission chain 10 adjusts the extension length of the guide shaft 1 according to the specifications of the bagged material 4. The drive sprocket 11 and the transmission chain 10 transmit torque to the roller 13 to rotate in the direction of the bagged material's movement. When the bagged material 4 moves to the bottom of the roller 13 and slowly passes through, the roller 13 is slowly pushed upward, compressing the length of the rectangular spring 2. At the same time, the driven sprocket 14 also moves upward, driving the transmission chain 10 to be further tensioned, pushing the connecting rod support 7 towards the middle. Since the end of the connecting rod support 7 is fixed in the waist-shaped hole of the guide groove plate 6, the connecting rod support 7 can only compress the circular spring 5 upward to offset the generated tension. The semi-circular pressure strip on the roller 13 provides a forward thrust to the bagged material 4 when rotating, ensuring that the material does not slip in place and enhancing the squeezing and loosening effect, which is more conducive to squeezing the material into a loose state. After the bagged material 4 has completely passed through, the circular spring 5 applies a downward elastic force, and the connecting rod support 7 pushes the tensioning sprocket to both sides, restoring the device to its initial state.

[0045] This invention utilizes a servo motor installed inside the drive sprocket. The servo motor drives the drive sprocket to rotate, allowing the roller to rotate synchronously with the conveyor belt. This reduces sliding friction between the bagged material and the conveyor belt. The semi-circular pressure strip on the roller provides forward thrust to the bagged material during rotation, preventing slippage and enhancing the compression and loosening effect. Four sets of rectangular springs ensure uniform downward pressure, and the pressure can be increased or decreased as needed by adjusting the guide shaft length to accommodate different sizes of bagged material. The roller always remains firmly pressed against the upper surface of the bagged material, ensuring sufficient downward pressure to compress and disperse it. The connecting rod support ensures the sprocket remains taut, guaranteeing normal rotation and solving the problem of skipped teeth caused by chain length changes during sprocket movement. Without requiring precision equipment, the coordinated mechanism effectively compresses and loosens clumps of powdery or flaky bagged material.
