Description

Technical Field

[0001] This utility model relates to the field of feeding equipment, and in particular to a semi-automatic feeding rack. Background Technology

[0002] Laser tube cutting machines are generally equipped with a loading rack for transporting tubes. Existing loading racks mainly consist of a motor, a hollow crossbeam, two sprockets rotating on the crossbeam, a chain, and multiple limiting blocks on the chain. Storage slots are formed between adjacent limiting blocks, and the tubes are confined within their corresponding slots. The motor drives the sprockets via a drive shaft, causing the chain to rotate and thus transporting the tubes towards the laser machine bed. Because the chain winds through (passes through) the hollow crossbeam, insufficient chain tension causes it to sag due to gravity and contact the inner wall of the crossbeam. During continuous chain movement, this friction generates noise and accelerates chain wear, shortening its lifespan. Furthermore, existing transmission components such as sprocket shafts, sprockets, and bearing seats must be individually installed onto the designated positions on the crossbeam, resulting in lengthy assembly times and low efficiency.

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

Detailed Implementation

[0022] This utility model provides a semi-automatic feeding 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.

[0023] Please see Figures 1-4This utility model provides a semi-automatic feeding rack, including multiple feeding racks 1 spaced apart, a feeding drive wheel 21 (sprocket) and a feeding driven wheel 22 (sprocket) rotatably mounted on the feeding racks 1, and a feeding chain 23 wound between the feeding drive wheel 21 and the feeding driven wheel 22. Multiple feeding limit blocks 24 are provided on the outer surface of the feeding chain 23, and a feeding storage slot is formed between two adjacent feeding limit blocks 24. The feeding drive wheel 21 is connected to a feeding drive mechanism 4. The feeding rack 1 includes a hollow crossbeam 11 and multiple vertical beams 13 fixed to the lower surface of the crossbeam 11. An elongated hole 111 extending along the length direction is provided on the lower surface of the crossbeam 11, and a support bar 12 extending along the length direction is provided on the upper surface of the crossbeam 11. The support bar 12 is used to support the feeding... Chain 23; A first slot 112 is provided upstream of the crossbeam 11, and a first U-shaped opening 113 with an upward opening is provided in the first slot 112. The feeding drive wheel 21 is penetrated by a first connecting shaft 211. A first bearing seat 212 is fixedly connected to the outer wall of the first U-shaped opening 113. The first connecting shaft 211 is rotatably connected to the first bearing seat 212. The first connecting shaft 211 is drively connected to the feeding drive mechanism 4. The feeding drive wheel 21 is rotatably disposed in the first slot 112. A second slot 114 is provided downstream of the crossbeam 11, and a second U-shaped opening 115 with an upward opening is provided in the second slot 114. The feeding driven wheel 22 is rotatably connected to the second connecting shaft 221 through a second bearing. The feeding driven wheel 22 is rotatably disposed in the second slot 114.

[0024] In use, the feeding drive mechanism 4 is activated, transmitting power to the first connecting shaft 211 of the feeding drive wheel 21. The first connecting shaft 211 drives the feeding drive wheel 21 to rotate. Since the feeding chain 23 is wound between the feeding drive wheel 21 and the feeding driven wheel 22, the rotation of the feeding drive wheel 21 will drive the feeding driven wheel 22 to rotate synchronously through the feeding chain 23, forming a closed-loop chain cycle motion. The feeding limiting block 24 on the outer side of the feeding chain 23 will limit the pipe through the feeding storage bay formed by the adjacent blocks, preventing the pipe from deviating or rolling off. As the feeding chain 23 cycles, the feeding limiting block 24 will drive the pipe in the feeding storage bay to move smoothly from upstream (feeding end) to downstream (laser machine body end) along the length direction of the crossbeam 11, completing the semi-automatic feeding action. During the operation of the feeding chain 23, the support bar 12 is always in contact with the lower surface of the feeding chain 23, providing upward support for the feeding chain 23, reducing the operating load of the feeding drive mechanism 4, and ensuring that the upper surface of the feeding chain 23 (and the feeding storage bayonet) remains in a horizontal and stable state, thereby improving the smoothness of pipe conveying.

[0025] The elongated holes 111 on the lower surface of the crossbeam 11 along its length provide a buffer space for the feeding chain 23 to sag. When the feeding chain 23 wears down due to long-term use, its tension decreases, or its initial tension is slightly insufficient, the feeding chain 23 will sag slightly due to its own weight. At this time, the hollow structure of the elongated holes 111 can directly avoid the sag of the chain, preventing the feeding chain 23 from contacting the inner wall of the crossbeam 11, thus fundamentally eliminating the feeding chain sag during movement. The friction between the feed chain 23 and the crossbeam 11 not only solves the noise problem but also reduces additional wear on the surface of the feed chain 23, extending its service life. At the same time, the support bar 12 on the upper surface of the crossbeam 11 and the elongated hole 111 work together to support the feed chain 23 from above, reducing the downward amplitude of the feed chain 23, while the elongated hole 111 provides clearance from below, catching any slight downward movement and improving the stability of the feed chain 23.

[0026] The first slot 112 and the first U-shaped opening 113 allow for pre-assembly followed by final assembly. Specifically, the feeding drive wheel 21, the first connecting shaft 211, and the first bearing seat 212 are pre-assembled, and then the pre-assembled assembly is directly placed into the first slot 112 from above. Finally, the first bearing seat 212 is fixedly connected to the outer wall of the first U-shaped opening 113. This eliminates the need for dispersing and installing individual components, as well as complex calibration inside the crossbeam 11, significantly reducing assembly steps and time. Furthermore, the second slot 114 and the second U-shaped opening 115 allow the feeding driven wheel 22 (pre-assembled with the second connecting shaft 221 and the second bearing) to be similarly inserted into the second slot 114 from above, further improving overall assembly efficiency and adapting to mass production needs.

[0027] Please see Figure 3 In some embodiments, a top block 213 is provided below the first bearing seat 212. The top block 213 is fixedly disposed on the outer side wall of the crossbeam 11. The top block 213 has a vertically extending pull threaded hole 214. A push rod (not shown in the figure) is threaded into the pull threaded hole 214. The end of the push rod is used to abut against the lower surface of the first bearing seat 212. When it is necessary to adjust the height of the first bearing seat 212 or to support and fix it, rotating the push rod can move it up and down along the pull threaded hole 214 until the end of the push rod abuts tightly against the lower surface of the first bearing seat 212. The above-mentioned settings can assist in calibrating the horizontal height of the first bearing seat 212 during assembly, ensuring that the axes of the feeding drive wheel 21 and the feeding driven wheel 22 remain parallel, and ensuring the smooth transmission of the feeding chain 23; they can also provide upward support for the first bearing seat 212 during equipment operation, reduce the stress load on the first connecting shaft 211 and the first bearing seat 212, avoid the first bearing seat 212 from shifting or loosening due to long-term operation, and further improve the stability and service life of the transmission system.

[0028] Please see Figure 4 In some embodiments, a stop plane 222 is provided on the peripheral wall of both ends of the second connecting shaft 221. An adjusting threaded hole is provided on the stop plane 222. A fixing block 31 is provided upstream or downstream of the second U-shaped opening 115. The fixing block 31 is fixedly provided on the outer wall of the crossbeam 11. An adjusting screw 32 that mates with the adjusting threaded hole passes through the fixing block 31. The head of the adjusting screw 32 presses against the fixing block 31 and the shank of the adjusting screw 32 is threadedly connected to the adjusting threaded hole. An adjusting nut 33 is threadedly connected to the shank of the adjusting screw 32. The adjusting nut 33 and the head of the adjusting screw 32 together clamp the fixing block 31. The above setup adjusts the tension of the feeding chain 23 by adjusting the position of the second connecting shaft 221, specifically as follows: The adjusting threaded hole engages with the fixing block 31. When adjusting the tension of the feeding chain 23, the clamping of the adjusting nut 33 and the adjusting screw 32 is loosened. By rotating the adjusting screw 32, the second connecting shaft 221 moves back and forth along the second U-shaped opening 115, thereby changing the distance between the driven feeding wheel 22 and the driving feeding wheel 21. After the tension of the feeding chain 23 reaches a suitable level, the adjusting nut 33 is retightened, causing the head of the adjusting screw 32 and the adjusting nut 33 to clamp the fixing block 31 again, fixing the position of the second connecting shaft 221, thus achieving precise adjustment and stable maintenance of the tension of the feeding chain 23.

[0029] Please see Figure 1 and Figure 2 In some embodiments, a limiting shaft plate 15 is provided on the outer wall of the second U-shaped opening 115, and the limiting shaft plate 15 is fixedly disposed on the outer wall of the crossbeam 11. When the pipe is conveyed to the loading station and stops, the limiting shaft plate 15 can act as a physical blocking structure to prevent the pipe from continuing to slide downstream due to inertia, effectively preventing the pipe from sliding out from the end of the crossbeam 11, avoiding damage to the pipe from falling or affecting the subsequent loading process.

[0030] Please see Figure 2 and Figure 4In some embodiments, a travel sensing mechanism 5 for sensing the pipe is provided upstream of the axis limiting plate 15. The travel sensing mechanism 5 includes a support plate 51 fixed to the outer wall of the crossbeam 11, a travel switch 52 disposed on the support plate 51, and a material receiving pressure plate 53 disposed on the output end of the travel switch 52. The travel sensing mechanism 5 is mainly used to automatically detect whether the pipe has been transported to the loading station. When the pipe triggers the travel sensing mechanism 5, it means that the pipe has been transported to the correct position. At this time, the travel sensing mechanism 5 sends a feedback signal to the control system, and the control system controls the feeding drive mechanism 4 to stop working until the pipe is fully loaded. The feeding drive mechanism 4 then restarts to realize the automatic loading and transportation of the next pipe. Specifically, when the pipe is conveyed to the position of the receiving plate 53, the receiving plate 53 presses down, triggering the limit switch 52. The control system controls the feeding drive mechanism 4 to stop conveying the pipe. After the pipe is fed to leave the crossbeam 11, the receiving plate 53 resets due to the loss of the downward pressure of the pipe and separates from the limit switch 52. Only then does the control system control the feeding drive mechanism 4 to run again.

[0031] Please see Figure 4 In some embodiments, a positioning sensor 61 (the mounting plate of the positioning sensor 61 is shown in the figure) is also provided upstream of the material feeding plate 53. A plurality of spaced sensing plates 62 are fixedly connected to the feeding limiting block 24, and the positioning sensor 61 is used to sense the sensing plates 62. When the sensing plate 62 passes the position of the positioning sensor 61, the feeding chain 23 pauses its movement. The feeding chain 23 will continue to rotate after the pipe at the downstream end of the feeding chain 23 has been fed, so as to transport the next pipe downstream.

[0032] Please see Figure 3 In some embodiments, the feeding drive mechanism 4 includes a feeding motor mounting plate 41 disposed on the side wall of the vertical beam 13, a feeding drive motor 42 disposed on the feeding motor mounting plate 41, a feeding drive sprocket 43 disposed on the output end of the feeding drive motor 42, a feeding driven sprocket 44 sleeved on the end of the first connecting shaft 211, and a feeding drive chain 45 wound between the feeding drive sprocket 43 and the feeding driven sprocket 44. When it is necessary to transport pipes, the output end of the feeding drive motor 42 rotates, driving the feeding drive sprocket 43 to rotate. Under the transmission of the feeding drive chain 45 and the feeding driven sprocket 44, the first connecting shaft 211 is driven to rotate, which in turn drives the feeding drive wheel 21 on the first connecting shaft 211 to rotate, providing power to the feeding chain 23.

[0033] Please see Figure 1 and Figure 3In some embodiments, the end of the first connecting shaft 211 is also connected to the drive shaft 47 via a coupling 46, the drive shaft 47 being used to connect adjacent first connecting shafts 211. Since the feeding rack consists of multiple spaced feeding racks 1, each feeding rack 1 is equipped with a first connecting shaft 211. Adjacent first connecting shafts 211 are connected via the drive shaft 47, and the installation deviation between adjacent shafts is eliminated by the coupling 46. This allows the power of the feeding drive mechanism 4 to be synchronously transmitted to the first connecting shafts 211 of all feeding racks 1, ensuring that the feeding drive wheels 21 of multiple feeding racks 1 rotate at the same speed and rotate synchronously.

[0034] Please see Figure 1 In some embodiments, the upstream vertical beams 13 are fixedly connected to each other by connecting beams 14, and the downstream vertical beams 13 are fixedly connected to the bed by connecting plates 16. This connection method allows each feeding rack 1 to be independently disassembled. During transportation, the entire feeding rack can be disassembled into individual feeding racks 1 and connecting beams 14, significantly reducing packaging and transportation volume and lowering the risk of damage during transport. During installation, each feeding rack 1 is first transported to the designated location, then the upstream vertical beams 13 are assembled and fixed using the connecting beams 14, and the downstream vertical beams 13 are precisely connected to the bed using the connecting plates 16. This eliminates the need to transport the entire heavy frame, simplifying the installation process.

[0035] In summary, this utility model provides a downward buffer space for the feeding chain 23 by creating an elongated hole 111 in the crossbeam 11, thus preventing the feeding chain 23 from contacting the inner wall of the crossbeam 11. The pre-assembly of transmission components is achieved through the first slot 112, the first U-shaped opening 113, the second slot 114, and the second U-shaped opening 115, improving assembly efficiency.
