Detailed Implementation
[0025] The following are specific embodiments of this application, described in conjunction with the accompanying drawings, to further illustrate the technical solutions of this application. However, this application is not limited to these embodiments. In the following description, specific details such as particular configurations and components are provided merely to aid in a comprehensive understanding of the embodiments of this application. Therefore, those skilled in the art should understand that various changes and modifications can be made to the embodiments described herein without departing from the scope of protection of this application. Furthermore, for clarity and brevity, descriptions of known functions and structures have been omitted.
[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.
[0027] This application provides an inner cylinder feeding bin for use as an inner cylinder filling device in a fireworks production line. During fireworks production, operators can place the inner cylinder in the inner cylinder feeding bin and feed it with material, continuously supplying inner cylinders to fill the combined fireworks. Currently, some feeding bins contain multiple material troughs separated by partitions. Due to structural design issues related to the partitions, the material troughs are only suitable for inner cylinders of specific lengths and cannot be flexibly adjusted according to the inner cylinder size, resulting in poor versatility. Therefore, this application provides an inner cylinder feeding bin that can be used with inner cylinders of various sizes and specifications. The following is a detailed description of the inner cylinder feeding bin with reference to the accompanying drawings.
[0028] In this embodiment, the inner cylinder feeding hopper includes baffles and multiple adjustable partitions. The baffles include a first side baffle and a second side baffle, which are located in opposite positions and form a storage space between them. Multiple adjustable partitions are horizontally placed between the first side baffle and the second side baffle to divide the storage space between the first side baffle and the second side baffle to form multiple sub-material troughs. The spacing width of the sub-material troughs can be changed by adjusting the installation position of the adjustable partitions. The width of each sub-material trough can be adjusted by changing the installation position, thereby adapting to inner cylinders of different sizes and specifications. It can be used for inner cylinders of various sizes and specifications.
[0029] Figure 1 This application illustrates the structure of an exemplary inner cylinder feeding hopper. Figure 1 In the structure shown, the inner cylinder feeding hopper includes a first side baffle 10a and a second side baffle 10b, and a plurality of adjustable partitions 20. The first side baffle 10a and the second side baffle 10b are positioned opposite each other, forming a storage space between them. The plurality of adjustable partitions 20 are horizontally positioned between the first side baffle 10a and the second side baffle 10b to divide the storage space between them, forming a plurality of sub-feed troughs 40. The spacing width of the sub-feed troughs 40 can be changed by adjusting the installation position of the adjustable partitions 20.
[0030] Specifically, a plurality of adjustable partitions 20 are arranged between the first side baffle 10a and the second side baffle 10b. The plurality of adjustable partitions 20 divide the storage space between the first side baffle 10a and the second side baffle 10b into a plurality of sub-material troughs 40. When the installation position of the adjustable partitions 20 is adjusted, the spacing width of the sub-material troughs 40 changes accordingly.
[0031] refer to Figure 1 , Figure 2 and Figure 6 In one embodiment of this application, the first side baffle 10a and the second side baffle 10b are provided with a plurality of opening slots 11 around the adjustable partition 20. For any adjustable partition 20, a plurality of connecting portions 21 are provided on its edge near the first side baffle 10a and its edge near the second side baffle 10b. The connecting portions 21 correspond to the positions of the opening slots 11 and are inserted into the corresponding opening slots 11. The opening slots 11 are elongated and extend horizontally, allowing the connecting portions 21 to move and adjust in their extending direction to change the spacing between adjacent adjustable partitions 20.
[0032] Specifically, the second side baffle 10b is provided with an opening groove 11, which extends horizontally and is elongated. In one embodiment of this application, the first side baffle 10a is provided with at least two opening grooves 11 at different positions around the adjustable partition 20, and the second side baffle 10b is provided with at least two opening grooves 11 at different positions around the adjustable partition 20. Figure 1 and Figure 2In the structure shown, for any adjustable partition 20, the second side baffle 10b has two opening slots 11 arranged vertically. The adjustable partition 20 has connecting portions 21 at positions corresponding to the two opening slots 11, which are then inserted into the corresponding opening slots 11. Similarly, a similar structure can be arranged on one side of the first side baffle 10a. In one specific embodiment, for any adjustable partition 20, the first side baffle 10a has two opening slots arranged vertically, and the adjustable partition 20 has connecting portions at positions corresponding to the two opening slots, which are then inserted into the corresponding opening slots. For any adjustable partition 20, the first side baffle 10a and the second side baffle 10b have several opening slots 11 around the adjustable partition 20. Therefore, the opening slots 11 are arranged on the first side baffle 10a and / or the second side baffle 10b. In other words, for any adjustable partition 20, one or more opening slots 11 are arranged on the first side baffle 10a, and one or more opening slots 11 are arranged on the second side baffle 10b. Accordingly, refer to... Figure 5 The adjustable partition 20 has two connecting parts 21 arranged on one side of the first side baffle 10a and two connecting parts 21 arranged on one side of the second side baffle 10b.
[0033] Furthermore, the opening slot 11 is elongated and extends horizontally, allowing the adjustable partitions 20 to move and adjust along its extension direction to change the spacing between adjacent adjustable partitions 20, thereby accommodating inner cylinders of different sizes. In terms of length, the elongated opening slot 11 is sufficient to accommodate the connecting portions 21 of multiple adjustable partitions 20, allowing for a wide range of adjustment during adjustment. Additionally, the elongated shape and horizontal extension of the opening slot 11 prevent the inner cylinder from passing through, thus preventing it from falling into the feed trough.
[0034] refer to Figure 3 and Figure 4 In one embodiment of this application, the connecting portions 21 of the plurality of adjustable partitions 20 are provided with connecting holes 22 at corresponding positions; the inner cylinder feeding hopper also includes connecting rods 50, which pass sequentially through the connecting holes 22 on the plurality of adjustable partitions 20 to connect the plurality of adjustable partitions 20 together. Here, the connecting rods 50 are used to connect the plurality of adjustable partitions 20 together to form a stable structure. Further, the connecting rods 50 are fitted with limiting sleeves 51 between adjacent adjustable partitions 20 to limit the plurality of adjustable partitions 20. The limiting sleeves 51 can restrict the adjustable partitions 20 from sliding on the connecting rods 50, and are used to limit the adjustable partitions 20 to a fixed position on the connecting rods 50.
[0035] Furthermore, the connecting portion 21 of the adjustable partition 20 is provided with a snap-fit notch 23, which can snap onto the lower edge of the opening slot 11. Here, the snap-fit notch 23 snaps into the lower edge of the opening slot 11, making the adjustable partition 20 more tightly connected with the first side baffle 10a and the second side baffle 10b, preventing the adjustable partition 20 from shaking.
[0036] refer to Figure 1 and Figure 3 In one embodiment of this application, the inner cylinder feeding bin further includes a fixed partition 30 whose position is not adjustable. The fixed partition 30 is horizontally placed between the first side baffle 10a and the second side baffle 10b and is parallel to the adjustable partition 20. Multiple adjustable partitions 20 are distributed on both sides of the fixed partition 30 and together with the fixed partition 30, they divide the storage space to form multiple sub-material troughs 40.
[0037] Specifically, multiple adjustable partitions 20 are distributed on both sides of the fixed partition 30, forming two sets of adjustable partitions 20 on each side of the fixed partition 30. Figure 1 and Figure 3 In the structure shown, the number of adjustable partitions 20 on both sides of the fixed partition 30 is equal. Five adjustable partitions 20 are provided on the first side of the fixed partition 30, and five adjustable partitions 20 are provided on the second side of the fixed partition 30. The position of the adjustable partitions 20 on both sides is adjusted with reference to the middle fixed partition 30. Furthermore, the opening slot 11 is interrupted at the fixed partition 30, and the adjustable partitions 20 on both sides are located in their respective opening slots 11. Moreover, the adjustable partitions 20 on the same side share the same opening slot 11, and the spacing is adjusted in the same opening slot 11.
[0038] refer to Figure 1 In one embodiment of this application, connecting side plates 60 are respectively provided at both ends of the first side baffle 10a and the second side baffle 10b; the connecting side plates 60 are detachably connected to the first side baffle 10a and the second side baffle 10b respectively. In this design, the first side baffle 10a, the second side baffle 10b, and the connecting side plates 60 at both ends form a stable frame structure. Furthermore, the connecting side plates 60 are connected to the first side baffle 10a and the second side baffle 10b using bolts.
[0039] refer to Figure 1 In one embodiment of this application, the first side baffle 10a is inclined and tilted away from the second side baffle 10b; the second side baffle 10b is vertically arranged.
