DETAILED DESCRIPTION
[0036] The following are specific embodiments of the present application and, in conjunction with the accompanying drawings, further description of the technical solutions of the present application is provided, but the present application is not limited to these embodiments. In the following description, specific details such as specific configurations and components are provided solely to assist in a comprehensive understanding of the embodiments of the present application. Therefore, it should be clear to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of protection of the present application. In addition, for clarity and brevity, descriptions of known functions and configurations have been omitted.
[0037] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.
[0038] This application provides a hopper assembly for firework inner tubes, comprising a fixed hopper and a transfer hopper. The fixed hopper has a first cavity inside that can accommodate the inner tube, while the transfer hopper has a second cavity inside that can accommodate the inner tube. The fixed hopper is fixedly mounted; the transfer hopper is movable and can be coupled to or separated from the fixed hopper. When the transfer hopper and the fixed hopper are coupled, the inner tube in the first cavity can be transferred to the second cavity. During operation, the inner tube is first loaded into the transfer hopper and then transferred from the transfer hopper to the fixed hopper, allowing the inner tube to be loaded away from the equipment for greater safety.
[0039] refer to Figure 1 and Figure 2 The hopper assembly includes a fixed hopper 10 and a transfer hopper 20. The fixed hopper 10 has a first cavity 11 inside that can accommodate an inner barrel, while the transfer hopper 20 has a second cavity 21 inside that can accommodate an inner barrel. The fixed hopper 10 is fixedly installed; the transfer hopper 20 is movable and can be connected to or separated from the fixed hopper 10. When the transfer hopper 20 and the fixed hopper 10 are connected, the inner barrel of the first cavity 11 can be transferred to the second cavity 21.
[0040] The transfer hopper 20 can be coupled or separated from the fixed hopper 10. During operation, the transfer hopper 20 can be moved to position A to load the inner barrel. After loading the inner barrel at the loading position, the transfer hopper 20 is moved to the position where the fixed hopper 10 is located and coupled with the fixed hopper 10. In this coupled state, the inner barrel in the transfer hopper 20 is transferred to the fixed hopper 10, completing the loading of the inner barrel. As can be seen, during the loading process of the hopper assembly, the inner barrel loading position can be kept away from the equipment, making loading operations safer for operators.
[0041] It should be noted that the transfer hopper 20's ability to move simply means that it can be moved, either manually or by automated equipment. Furthermore, the connection between the transfer hopper 20 and the fixed hopper 10 is used to transfer the inner barrel from the transfer hopper 20 to the fixed hopper 10. Therefore, a fixed connection between the transfer hopper 20 and the fixed hopper 10 is not required; the connection can be either fixed or non-fixed, as long as the connection allows the inner barrel to be transferred.
[0042] In one embodiment of the present application, a first drop opening 12 is provided at the bottom of the fixed hopper 10, and a first feed opening 13 is provided at the top. Figure 3 and Figure 4The bottom of the transfer hopper 20 is provided with a second drop opening 22; the transfer hopper 20 is equipped with a material stopper 30, which can open or close the second drop opening 22. When the bottom of the transfer hopper 20 is combined with the top of the fixed hopper 10, as the material stopper 30 opens the second drop opening 22, the inner cylinder of the first material cavity 11 falls downward into the second material cavity 21. Figure 1 and Figure 2 In the structure shown, the transfer hopper 20 is combined with or separated from the fixed hopper 10 from above. In the combined state, when the blocking member 30 opens the second drop opening 22 , the inner cylinder in the transfer hopper 20 falls downward into the fixed hopper 10 .
[0043] In one technical solution, an operator manually operates the stopper 30 to open or close the second blanking opening 22. Specifically, the stopper 30 can be opened or closed by pulling. In another technical solution, the stopper 30 is driven by a driving device to open or close the second blanking opening 22. The driving device can be a pneumatic cylinder, an electric cylinder, etc., and its type can be set according to actual conditions.
[0044] refer to Figure 3 and Figure 4 In one embodiment of the present application, the retaining member 30 is a plate-like structure with ash holes 31 disposed thereon to allow powder to pass through. When the transfer hopper 20 is loaded into the inner drum at the loading position, powder leaking from the inner drum can be promptly discharged through the ash holes 31 and will not be carried into the fixed hopper 10. This can avoid safety issues caused by leaking powder during subsequent pushing and filling.
[0045] refer to Figure 3-Figure 6 In one embodiment of the present application, a plurality of positioning pins 14 are provided on the top of the fixed hopper 10; a plurality of positioning holes 23 are provided on the bottom of the transfer hopper 20; the positioning pins 14 correspond one-to-one with the positioning holes 23; when the bottom of the transfer hopper 20 is coupled with the top of the fixed hopper 10, the positioning pins 14 are inserted one-to-one into the positioning holes 23. When the operator couples the transfer hopper 20 with the fixed hopper 10 from above, the positioning pins 14 can be inserted one-to-one into the positioning holes 23. Due to the cooperation between the positioning pins 14 and the positioning holes 23, the transfer hopper 20 and the fixed hopper 10 are precisely docked, and the second drop port 22 at the bottom of the transfer hopper 20 is aligned with the first feed port 13 at the top of the fixed hopper 10, so that the inner cylinder in the transfer hopper 20 can smoothly drop downward into the fixed hopper 10.
[0046] In one embodiment of the present application, a plurality of positioning holes are provided on the top of the fixed hopper; a plurality of positioning pins are provided on the bottom of the transfer hopper; the positioning pins correspond to the positioning holes one-to-one; when the bottom of the transfer hopper is combined with the top of the fixed hopper, the positioning pins are inserted into the positioning holes one-to-one. Similar to the previous embodiment, the difference is that the positions of the positioning pins and the positioning holes are swapped. Similarly, when the operator combines the transfer hopper with the fixed hopper from above, the positioning pins can be inserted into the positioning holes one-to-one. Due to the cooperation between the positioning pins and the positioning holes, the transfer hopper and the fixed hopper are precisely docked, and the second feed port at the bottom of the transfer hopper is aligned with the first feed port at the top of the fixed hopper, so that the inner cylinder in the transfer hopper can smoothly fall down into the fixed hopper.
[0047] In one embodiment of the present application, reference Figure 5 A circle of positioning grooves 15 is provided on the top of the fixed hopper 10 around the first feed port 13. Figure 3 and Figure 4 , a flange 24 is provided around the bottom of the transfer hopper 20. Figure 6 The flange 24 fits into the positioning groove 15; when the bottom of the transfer hopper 20 is combined with the top of the fixed hopper 10, the flange 24 is installed in the positioning groove 15. When the operator combines the transfer hopper with the fixed hopper from above, the flange 24 is installed in the positioning groove 15. Due to the positioning and cooperation between the flange 24 and the positioning groove 15, the transfer hopper and the fixed hopper are precisely connected. The second drop-out port at the bottom of the transfer hopper is aligned with the first feed port at the top of the fixed hopper, so that the inner cylinder in the transfer hopper can smoothly drop down into the fixed hopper.
[0048] In one embodiment of the present application, a plurality of clamping mechanisms 40 are installed on the top of the fixed hopper 10; when the bottom of the transfer hopper 20 is combined with the top of the fixed hopper 10, the clamping mechanism 40 can press the flange 24 around the bottom of the transfer hopper 20 downward onto the top of the fixed hopper 10. When the clamping mechanism 40 presses the flange 24 around the bottom of the transfer hopper 20 downward onto the top of the fixed hopper 10, the transfer hopper 20 and the fixed hopper 10 are tightly combined together. At this time, the operator can operate the blocking member 30 to open the second drop opening 22, so that the inner cylinder of the first material cavity 11 falls downward into the second material cavity 21. When the clamping mechanism 40 removes the restriction on the transfer hopper 20, the transfer hopper 20 can be separated from the fixed hopper 10 from above. In addition, the clamping mechanism 40 can be an electric mechanism, a pneumatic mechanism, or a manual mechanism, etc., and can be specifically set according to needs.
[0049] In one embodiment, the clamping mechanism 40 includes a base 41, a clamping arm 42, an operating arm 43, and a movable connection 44. The base 41 is fixed to the top of the fixed hopper 10, the clamping arm 42 is rotatably mounted on the base 41, and the operating arm 43 is rotatably mounted on the base 41 and is configured to receive a rotation operation. The movable connection 44 is movably connected to the clamping arm 42 and the operating arm 43, respectively. As the operating arm 43 rotates, the operating arm 43 drives the clamping arm 42 through the movable connection 44 to rotate downward to clamp the flange 24 around the bottom of the transfer hopper 20, or to rotate upward to release the flange 24 around the bottom of the transfer hopper 20. Here, the operating arm 43 can be rotated by an operator.
[0050] In one embodiment of the present application, the fixed hopper has a first discharge opening at the bottom and an open top. A transfer hopper has a second discharge opening at the bottom, equipped with a retaining member that can open and close the second discharge opening. When the transfer hopper is inserted downward into the fixed hopper, the retaining member opens the second discharge opening, allowing the inner barrel of the first cavity to drop downward into the second cavity. This differs from the previous section and the accompanying drawings in that the transfer hopper can be inserted downward into the fixed hopper to discharge material.
[0051] The embodiment of the present application further provides an inner tube filling device, which has the above-mentioned hopper assembly for firework inner tubes.
[0052] The hopper assembly includes a fixed hopper and a transfer hopper; the interior of the fixed hopper is provided with a first material cavity capable of accommodating an inner cylinder; the interior of the transfer hopper is provided with a second material cavity capable of accommodating an inner cylinder. The fixed hopper is installed in a fixed manner; the transfer hopper is movable and can be combined with or separated from the fixed hopper; when the transfer hopper and the fixed hopper are combined, the inner cylinder of the first material cavity can be transferred to the second material cavity. During operation, the transfer hopper can be transferred to position A to load the inner cylinder. After the transfer hopper is loaded with the inner cylinder at the loading position, it is transferred to the position where the fixed hopper is located and combined with the fixed hopper. In the combined state, the inner cylinder in the transfer hopper is transferred to the fixed hopper, thereby completing the loading of the inner cylinder. It can be seen that during the loading process of the above-mentioned hopper assembly, the loading position of the inner cylinder can be far away from the equipment, which is safer for the operator when performing the loading operation. For more specific instructions, please refer to the description of the hopper assembly in the previous section, which will not be repeated here.
