Description

Technical Field

[0001] This utility model relates to the field of textile machinery, and more specifically, to a drum core and a drum device. Background Technology

[0002] In the production process of a silk reeling machine, the process from drawing the silk to winding it requires multiple drum units. Existing drum units are typically assembled from components such as the drum core, drum screws, nuts, drum cover, and drum frame. However, this structure has the following problems: First, the stainless steel drum core and the plastic drum are prone to loosening and shifting, leading to unstable operation. Second, the drum frame is made of bent stainless steel plate, which involves complex processing, and the coaxiality of the two screw holes on the existing drum frame plate is difficult to guarantee, further affecting the overall assembly accuracy and rotational flexibility of the drum, thus affecting the working state of the entire silk reeling system and increasing reeling tension, which in turn affects the quality of the raw silk. Therefore, the existing drum unit still has significant room for improvement, and a more stable and reliable drum unit is urgently needed to enhance the overall performance of the silk reeling machine.

[0029] Please refer to the following: Figure 4 , Figure 5 , Figure 6 The present invention provides a drum core according to an embodiment. A drum core includes a core component 15 manufactured by injection molding, the core component 15 having a through hole 115 in the middle, and a rotating connector 13 coaxial with the through hole 115 connected to the middle of the core component 15. The rotating connector 13 can be made of stainless steel ball bearings. The core component 15 can be rotatably connected to the drum mounting base 5 through the rotating connector 13. This invention does not use a drum frame; the drum core can be used as an independent basic working unit, assembled with different drum mounting components to form different types of drum devices, applicable to, but not limited to, equipment such as double-wire machines and sample testing machines.

[0030] The wheel core component 15 includes two wheel core end pieces 11 arranged opposite to each other. The rotating connector 13 is positioned between the two wheel core end pieces 11 by clamping to limit the axial displacement of the rotating connector 13.

[0031] The wheel core component 15 includes two oppositely arranged wheel core end pieces 11, and a ceramic ring 12 is fixed between the two wheel core end pieces 11 by clamping. The ceramic ring 12 is used to position the wire.

[0032] Since the wheel core end piece 11 is made of one-time plastic injection molding, the two wheel core end pieces 11 are simultaneously opened with positioning grooves 111 for installing the rotating connector 13 and the ceramic ring 12 during the production process.

[0033] Fasteners 14 are connected between the two wheel core end plates 11. The fasteners 14 include, but are not limited to, fastening screws and countersunk screws. The two wheel core end plates 11 are provided with threaded holes 114 and countersunk holes 113 that match the fastening screws and countersunk screws, respectively.

[0034] Please refer to the following: Figure 1 , Figure 2 , Figure 3 This utility model also provides a drum device, including a drum core 1 as described above. The rotating connecting member 13 of the drum core 1 is sleeved on the outside of the supporting member 7 and is rotatably connected to the supporting member 7. The drum device also includes a drum mounting member 8, which is an integrally formed structure. Specifically, the drum mounting member 8 is manufactured by injection molding. The drum mounting member 8 is fixedly connected to the supporting member 7. The drum core 1, the supporting member 7, and the drum mounting member 8 are coaxially arranged.

[0035] Both ends of the support component 7 are provided with fastening ends, and the two fastening ends abut against the two outer sides of the drum mounting component 8 respectively; mechanical fasteners 6 are abutting against both sides of the drum core 1 on the support component 7, and the other ends of the two mechanical fasteners 6 abut against the inner wall of the drum mounting component 8 respectively. In this embodiment, the mechanical fasteners 6 can be shaft retaining rings to prevent axial movement of the various components on the support component. The drum mounting component 8 is positioned on the support component 7 by the fastening ends and the mechanical fasteners 6.

[0036] In this embodiment, the support component 7 can be selected from drum screw 71 and drum nut 72. The end of drum screw 71 and drum nut 72 respectively constitute the two fastening ends of the support component 7.

[0037] The drum mounting component 8 includes two drum mounting seats 5 arranged opposite to each other on the support component 7. The inner walls of the two drum mounting seats 5 are provided with positioning support grooves that cooperate with the corresponding mechanical fasteners 6. Since the drum mounting seats 5 are made of one-time plastic injection molding, the above-mentioned positioning support grooves 51 are opened simultaneously in the production process of the two drum mounting seats.

[0038] The drum mounting component 8 is sleeved on the outside of the drum core component 15, and has an annular opening in the middle for the wire to enter and exit. Figure 7 As shown, the inner wall of the drum mounting component 8 does not directly contact the drum core 1, and has a gap that ensures the smooth rotation of the drum core 1.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
