Abstract
Description
Technical Field
[0001] This utility model relates to a pellet loading device. Background Technology
[0002] In China, many companies still use manual granule loading for packaging raw material supply, which is labor-intensive and increases the workload for workers. Although some manufacturers have produced automatic loading equipment, the equipment is complex in structure, requires a lot of power, and consumes a lot of energy. Utility Model Content
[0003] This utility model proposes a pellet loading device, including a support column, a lifting mechanism, and a loading mechanism. An installation platform is mounted on the support column. The loading mechanism and the lifting mechanism are mounted on the installation platform. The loading mechanism is equipped with a loading pipe with a feed inlet. A clamp is provided at the feed inlet, and a suction tube or suction bag is fitted onto the feed inlet and clamped by the clamp. A lifting platform is located below the installation platform, and multiple bag-hooking mechanisms are provided on the lifting platform. These bag-hooking mechanisms hook onto ton bags. The lifting mechanism is connected to the lifting platform and drives the lifting platform to rise and fall. The lifting mechanism drives the lifting platform down to the ton bag position. After the bag-hooking mechanisms hook onto the ton bag, the lifting mechanism drives the lifting platform up until the suction tube or suction bag falls into the pellets. The loading mechanism is equipped with a negative pressure mechanism, which is connected to the loading pipe and sucks the pellets upwards. As the pellets decrease, the ton bag rises, keeping the suction tube or suction bag inside the pellets.
[0004] In one or more embodiments, a negative pressure fan is provided on the installation platform, and the negative pressure fan is connected to the loading pipe and feeds material in reverse to the inlet.
[0005] In one or more embodiments, a hydraulic pump is provided on the installation platform, the hydraulic pump is connected to a hydraulic cylinder of a lifting mechanism, the hydraulic cylinder is connected to a lifting platform, and the lifting force of the hydraulic cylinder is equal to or slightly less than the total weight of the ton bag and the material.
[0006] In one or more embodiments, the bag hook mechanism includes a housing, a drive mechanism, a hook arm, and an anti-loosening arm. The hook arm is axially connected to the housing, one end of the hook arm is connected to the drive arm, the drive arm is axially connected to both the hook arm and the drive mechanism, the anti-loosening arm is fixedly connected to the housing and extends toward the hook arm, and the drive mechanism drives the drive arm to move, thereby causing the hook arm to swing to approach or move away from the anti-loosening arm.
[0007] In one or more embodiments, a fixed bag-loosening bar is provided on the housing, the minimum height of which is slightly lower than the minimum swing height of the hook arm.
[0008] In one or more embodiments, the bag-loosening stick is positioned in the swing path of the hook arm to form a barrier to deflect bags hooked on the hook arm.
[0009] In one or more embodiments, the bag-removing bar forms a gate shape.
[0010] In one or more embodiments, when the hook arm approaches the anti-loosening arm, the hook arm portion is in contact with the anti-loosening arm.
[0011] The beneficial effects of this utility model are as follows: The lifting platform is driven to descend to the position of the ton bag by the lifting mechanism. After the bag hooking mechanism hooks the ton bag, the lifting mechanism drives the lifting platform to rise until the suction tube or suction bag falls into the granules. The loading mechanism is equipped with a negative pressure mechanism, which is connected to the loading pipe and sucks the granules upward. As the granules decrease, the ton bag rises and keeps the suction tube or suction bag inside the granules, which reduces the burden on the lifting mechanism, saves energy, extends the life of the lifting mechanism, and realizes continuous loading of granules.

[0016] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution:
[0017] See appendix Figure 1-4 A granule loading device includes a support column 1, a lifting mechanism 2, and a loading mechanism 3. An installation platform 4 is mounted on the support column 1. The loading mechanism 3 and the lifting mechanism 2 are mounted on the installation platform 4. The loading mechanism 3 has a loading pipe 31 with a feed inlet 32. A clamping plate 33 is installed at the feed inlet 32 and connected to a clamping cylinder. This clamping plate 33 is a direct application of existing technology. A suction tube or suction bag is fitted onto the feed inlet 32 and clamped by the clamping plate 33. A lifting platform 5 is located below the installation platform 4. The lifting platform 5 is equipped with multiple bag hooking mechanisms 6, which hook the ton bag. The lifting mechanism 2 is connected to the lifting platform 5 and drives the lifting platform 5 to rise and fall. The lifting mechanism 2 drives the lifting platform 5 to descend to the ton bag position. After the bag hooking mechanism 6 hooks the ton bag, the lifting mechanism 2 drives the lifting platform 5 to rise until the suction tube or suction bag falls into the granules. The loading mechanism 3 is equipped with a negative pressure mechanism 7. The negative pressure mechanism 7 is connected to the loading pipe 31 through a hose and sucks the granules upward. As the granules decrease, the ton bag rises and keeps the suction tube or suction bag inside the granules.
[0018] Furthermore, a negative pressure fan is provided on the installation platform 4 as a negative pressure mechanism 7. The negative pressure fan is connected to the loading pipe 31 and feeds material in the reverse direction to the inlet 32.
[0019] Furthermore, a hydraulic pump 8 is installed on the installation platform 4. The hydraulic pump 8 is connected to the hydraulic cylinder of the lifting mechanism 2. The hydraulic cylinder is connected to the lifting platform 5. The lifting force of the hydraulic cylinder is equal to or slightly less than the total weight of the ton bag and the material.
[0020] Furthermore, the hook bag mechanism includes a housing 61, a drive mechanism 63, a hook arm 62, and an anti-loosening arm 64. The hook arm 62 is axially connected to the housing 61, and one end of the hook arm 62 is connected to the drive arm 65. The drive arm 65 is axially connected to both the hook arm 62 and the drive mechanism 63. The anti-loosening arm 64 is fixedly connected to the housing 61 and extends toward the hook arm 62. The drive mechanism 63 drives the drive arm 65 to move, thereby causing the hook arm 62 to swing to approach or move away from the anti-loosening arm 64.
[0021] Furthermore, a fixed bag-loosening rod 66 is provided on the outer casing 61, and the lowest height of the bag-loosening rod 66 is slightly lower than the lowest swing height of the hook arm 62.
[0022] Furthermore, the bag-loosening stick 66 is positioned on the swing path of the hook arm 62 to form a barrier to block the bag hooked on the hook arm 62.
[0023] Furthermore, the bag-removing rod 66 forms a gate shape.
[0024] Furthermore, when the hook arm 62 approaches the anti-loosening arm 64, a portion of the hook arm 62 is in contact with the anti-loosening arm 64 and the lowest end of the hook arm is lower than the lowest end of the anti-loosening arm.
[0025] Furthermore, the drive mechanism 63 is formed as a horizontally arranged drive cylinder or hydraulic cylinder.
