Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a receiving rack. Background Technology

[0002] For chuck-type laser tube cutting equipment, the receiving of tubes is generally achieved using a receiving rack. However, for receiving short and tail sections, existing technologies typically use a receiving hopper. This involves multiple chucks clamping the tubes, which are then fed onto a receiving assembly and unloaded into a hopper located below the assembly. Because the receiving hopper is relatively close to the laser cutting and feeding area, it poses two problems: firstly, it is unsafe for operators to be near this area; secondly, when short / tail sections fall into the hopper, tubes tend to accumulate near this area, while other areas of the hopper are underutilized due to the lack of tubes falling into them. This necessitates frequent repositioning of the receiving hopper to ensure efficient use of its space.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a receiving rack, which aims to improve the problem of using a receiving hopper to receive short / tail materials.

[0025] This utility model provides a receiving rack. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0026] Please see Figure 1 This utility model provides a receiving rack, including a plurality of spaced-apart receiving and conveying assemblies 20; the receiving and conveying assemblies 20 are used to convey pipes from upstream to downstream; the receiving rack also includes a short material conveying assembly 10 disposed beside the receiving and conveying assemblies 20 located at the edge. Please refer to [link to relevant documentation]. Figure 2 The short material conveying assembly 10 includes a base frame 1, a short material drive wheel 21 and a short material driven wheel 22 rotatably and symmetrically arranged on the base frame 1, and a short material chain 3 wound between the short material drive wheel 21 and the short material driven wheel 22. Multiple short material receiving plates 4 are arranged at intervals between the two short material chains 3 and extend in a direction perpendicular to the pipe conveying direction. The short material drive wheel 21 is connected to the short material driving mechanism 6 through the short material transmission shaft 5. The short material driving mechanism 6 is used to drive the short material chain 3 and the short material receiving plate 4 to rotate.

[0027] Specifically, both the short material drive wheel 21 and the short material driven wheel 22 are sprockets.

[0028] In practical applications, multiple receiving mechanisms (these are existing technologies and will not be described in detail) are spaced apart on the bed of the laser tube cutting machine. They are used to provide follow-up support for the tubes during processing and to guide the tubes after processing at an incline. Thus, the tubes can be guided to the corresponding receiving and conveying components 20 (multiple receiving and conveying components 20 are used to accommodate tubes of different lengths). In addition, for the receiving of short materials, the tubes are conveyed to the short material receiving plate 4 located upstream via the receiving mechanism. The control mechanism drives the short material drive mechanism 6 to start running, thereby driving the two short material chains 3 to rotate and simultaneously conveying the tubes on the short material receiving plate 4 located upstream to the downstream direction. When the receiving mechanism continues to unload the tubes, the tubes on the short material receiving plate 4 can be continuously conveyed downstream, realizing automatic receiving and conveying of short materials.

[0029] The aforementioned receiving rack, through the short material drive mechanism 6, utilizes the short material transmission shaft 5 and the short material drive wheel 21 and driven wheel 22 to drive the short material chain 3 to rotate while simultaneously displacing the short material receiving plate 4. This allows the pipes on the upstream short material receiving plate 4 to be continuously transported downstream. In conjunction with the receiving mechanism, it achieves automatic receiving and conveying of short materials.

[0030] Please see Figure 2In some embodiments, the base frame 1 includes two symmetrically arranged side plates 11 parallel to the pipe conveying direction, and a plurality of connecting beams 12 for connecting the two side plates 11. A first slot is opened at the upstream end of the two side plates 11, and the short material driven wheel 22 is rotatably disposed in the corresponding first slot, and the two short material driven wheels 22 are connected by a driven rod 23. A second slot is also opened at the downstream end of the two side plates 11, and the short material driving wheel 21 is rotatably disposed in the corresponding second slot, and the short material drive shaft 5 is used to connect the two short material driving wheels 21. The short material driving mechanism 6 is disposed beside any of the side plates 11. The side plates 11 are lighter than steel beams, and the two side plates 11 are connected by connecting beams 12 to improve the structural rigidity of the base frame 1. Bearing seats are provided in both the first and second slots. The bearing seats enable the driven rod 23 and the short material drive shaft 5 to rotate relative to the base frame 1. The driven rod 23 and the short material drive shaft 5 improve the synchronization of the two short material chains 3.

[0031] Please see Figure 2 In some embodiments, the side plate 11 is also fixedly connected to a plurality of height-adjustable feet 13. Large laser tube cutting machines occupy a large area, and when the factory floor is uneven, the levelness of the base frame 1 can be maintained by adjusting the height of the corresponding feet 13.

[0032] Please see Figure 2 and Figure 3 In some embodiments, the short material chain 3 includes multiple chain links 31 that rotate relative to each other, and inverted L-shaped support plates 32 disposed inside the corresponding chain links 31. The ends of the multiple short material receiving plates 4 are respectively fixed to the upper surface of the corresponding inverted L-shaped support plates 32. The conveyor belt-like structure formed by the short material receiving plates 4 has stronger structural rigidity, can withstand the impact of heavy / large short materials, and will not deform. Moreover, when it is necessary to replace the corresponding short material receiving plate 4, the corresponding short material receiving plate 4 can be removed from the inverted L-shaped support plate 32 and a new short material receiving plate 4 can be replaced. Subsequent maintenance is convenient and the cost is lower than replacing the entire conveyor belt.

[0033] Please see Figure 2 and Figure 3 In some embodiments, each of the two side plates 11 is further fixed with an inverted L-shaped guard plate 14, which is used to cover the short material chain 3. The inverted L-shaped guard plate 14 can prevent the pipe from directly contacting or impacting the short material chain 3, thereby improving the service life of the short material chain 3 and reducing the frequency of maintenance of the short material chain 3.

[0034] Please see Figure 2In some embodiments, a limiting beam 15 is also fixed to the upper surface of the inverted L-shaped guard plate 14 located on the outer side. The limiting beam 15 can prevent the pipe from slipping off the short material receiving plate 4 and protect the safety of the personnel located next to the short material conveying assembly 10.

[0035] Please see Figure 3 In some embodiments, the short material drive mechanism 6 includes a short material motor bracket 61, a short material drive motor 62 mounted on the short material motor bracket 61, a short material drive sprocket 63 mounted on the output end of the short material drive motor 62, a short material driven sprocket 64 sleeved on the short material transmission shaft 5, and a short material drive chain 65 wound between the short material drive sprocket 63 and the short material driven sprocket 64. When transporting the pipe, the short material drive motor 62 drives the short material drive sprocket 63 to rotate. Under the transmission of the short material drive chain 65 and the short material driven sprocket 64, the short material transmission shaft 5 is driven to rotate, which in turn drives the short material drive wheel 21 on the short material transmission shaft 5 to rotate, providing power to the short material chain 3.

[0036] Please see Figure 1 In some embodiments, the short material drive mechanism 6 is further covered by a short material protective cover 16; and the short material drive mechanism 6 is disposed on the side plate 11 near the edge of the receiving and conveying assembly 20. The short material protective cover 16 protects the short material drive mechanism 6 from external impacts, thus achieving the function of protecting the short material drive mechanism 6. In addition, placing the short material drive mechanism 6 on the inner side (the outer side is the operator's operating side) keeps the short material drive mechanism 6 away from the operating side, further improving safety performance.

[0037] Please see Figure 1 In some embodiments, the plurality of receiving and conveying assemblies 20 are detachably connected by a first connecting rod 71, and the inner side plate 11 and the edge receiving and conveying assembly 20 are detachably connected by a second connecting rod 72. The first connecting rod 71 and the second connecting rod 72 allow for the detachment of the plurality of receiving and conveying assemblies 20 and the short material conveying assembly 10, facilitating shipping and on-site installation.

[0038] Please see Figure 4In some embodiments, each of the multiple receiving and conveying assemblies 20 includes a frame 8, a receiving drive wheel 81 rotatably mounted on the frame 8, a receiving driven wheel 82, and a receiving chain 83 wound around the receiving drive wheel 81 and the receiving driven wheel 82. Multiple limiting blocks 84 are provided on the outer surface of the receiving chain 83, and a storage slot is formed between two adjacent limiting blocks 84. The receiving drive wheels 81 on the multiple receiving frames are connected by a receiving drive shaft 85. The receiving drive shaft 85 is connected to a receiving drive mechanism 9. The receiving drive mechanism 9 is used to drive the pipe in the receiving chain 83 and the storage slot to be conveyed downstream. Since the storage bays on the receiving chain 83 can be used to restrict the movement of the pipes, as the pipes are unloaded, the receiving drive mechanism 9 uses the short material drive wheel 21 and the short material driven wheel 22 to make the receiving chain 83 rotate from the upstream direction to the downstream direction, so that the pipes on each storage bay can be transported downstream one by one. When the pipes are transported to the downstream end, the pipes on the storage bay are unloaded, and the pipes can be transported out of the storage area to achieve continuous operation.

[0039] Please see Figure 3 and Figure 4 In this embodiment, the receiving drive mechanism 9 can adopt the same structure as the short material drive mechanism 6, thereby driving the receiving transmission shaft 85 to rotate.
