Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire manufacturing technology, specifically a dual-station feeding trolley with adjustable centering distance. Background Technology
[0002] Traditional giant tire forming machines use a dual-station feeding trolley for the inner lining layer, such as Figure 1 As shown, the two I-beam wheels 2 are respectively installed in two mounting brackets 1. When it is necessary to replace the I-beam wheels 2 or adjust different work positions, the moving motor 3 drives the feeding trolley to move left and right through the sprocket and chain. This structure has the following problems: 1. The positioning is inaccurate and cannot be fine-tuned, and it cannot meet the small spacing requirements of the two I-beam wheels; 2. The two independent I-beam wheels 2 move through their respective moving motors 3, and cannot be completely synchronized. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a dual-station feeding trolley with multi-level adjustable center distance. The adjustment method is more flexible, the positioning is accurate, and it can also feed materials synchronously, thus saving costs.
[0004] This utility model achieves the above objectives through the following technical solutions:
[0005] A dual-station feeding trolley with multi-level adjustable center distance includes a mounting frame and two I-beam wheels. The mounting frame has a square shaft inside, and the two I-beam wheels are slidably mounted side by side on the square shaft. The inner side of the I-beam wheels is connected to a stepped I-beam wheel connecting sleeve. A hollow screw is fitted in the middle section of the square shaft, and matching nuts are installed at both ends of the hollow screw. One end of the nut is connected to the nut connecting sleeve, and a pressure cap is connected to the I-beam wheel connecting sleeve. The nut connecting sleeve is snapped between the I-beam wheel connecting sleeve and the pressure cap.
[0006] Furthermore, the I-beams are connected to each other by bolts, the nuts are connected to each other by bolts, and the I-beams connecting sleeves are connected to the gland.
[0007] Compared with the prior art, the advantages and effects of this utility model are:
[0008] 1. By using the screw and nut together, the distance between the two I-beams can be minimized, and the distance can be finely adjusted in multiple stages, making the operation more flexible and the positioning more precise;
[0009] 2. A single square shaft drives two I-beam wheels to rotate simultaneously, achieving synchronous feeding and saving costs. Attached Figure Description

[0015] The present invention will be further described below with reference to the embodiments, but the present invention is not limited to these embodiments.
[0016] This embodiment describes a dual-station feeding trolley with multi-level adjustable mid-distance, such as... Figure 2 , 3 As shown in Figure 4, the device includes a mounting frame 1 and two I-beam wheels 2. A square shaft 4 is located inside the mounting frame 1. The two I-beam wheels 2 are slidably mounted side-by-side on the square shaft 4. A stepped I-beam wheel connecting sleeve 5 is bolted to the inner side of each I-beam wheel 2. A hollow screw 6 is welded to the middle section of the square shaft 4. Matching nuts 7 are installed at both ends of the hollow screw 6. One end of the nut 7 is bolted to a nut connecting sleeve 8. A pressure cap 9 is bolted to the I-beam wheel connecting sleeve 5. The nut connecting sleeve 8 engages in the gap formed between the stepped I-beam wheel connecting sleeve 5 and the pressure cap 9. When the nut 7 rotates, the nut connecting sleeve 8 can rotate with the nut 7 within the gap between the I-beam wheel connecting sleeve 5 and the pressure cap 9.
[0017] The working principle of this embodiment is as follows:
[0018] 1. When it is necessary to adjust the centering distance of the two I-beam wheels 2, rotate the nut 7 to move it to the left or right along the hollow screw 6 (i.e., square shaft 4), thereby driving the nut connecting sleeve 8, the I-beam wheel connecting sleeve 5, the pressure cap 9, and the I-beam wheel 2 to move synchronously, thus achieving the effect of adjusting the centering distance of the I-beam wheels 2.
[0019] 2. The two I-beam wheels 2 rotate with the same square shaft 4, which can achieve synchronous feeding.
