[0016] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.
[0017] Chuck-type laser tube cutting machines are generally equipped with a feeding rack in the feeding area. The feeding rack usually relies on a chain to move the tube. In the past, when the equipment malfunctioned or made abnormal noises, it was often necessary to stop the machine or even disassemble the equipment to check the meshing of the chain and sprocket to locate the problem. This method was cumbersome and affected work efficiency, which was not conducive to the continuous and smooth feeding process.
[0018] Therefore, this utility model proposes a feeding rack, referring to... Figures 1-5 It includes a drive assembly 100, multiple synchronous shafts 200, and multiple sets of spaced-apart feeding assemblies 300. Each set of feeding assemblies 300 includes a frame 310, a first sprocket 320, a second sprocket 330, a first chain 340, and multiple positioning components 350. The frame 310 includes a crossbeam 311, a first column 312, and a second column 313. The crossbeam 311 has an upstream end and a downstream end along the conveying direction. The top end of the first column 312 is fixedly connected to the lower surface of the upstream end of the crossbeam 311, and the top end of the second column 313 is fixedly connected to the lower surface of the downstream end of the crossbeam 311. A first slot 314 is opened at the upstream end of the crossbeam 311, and the first sprocket 320 is disposed in the first slot 314 and can rotate relative to the frame 310. A second slot 315 is opened at the downstream end of the crossbeam 311. The second sprocket 330 is disposed in the second slot 315 and is rotatable relative to the frame 310. Adjacent second sprockets 330 are connected by a synchronous shaft 200. The drive assembly 100 is connected to the synchronous shaft 200 to drive the synchronous shaft 200 to rotate. The first chain 340 is wound between the first sprocket 320 and the second sprocket 330. The upper half of the first chain 340 runs along the upper surface of the crossbeam 311, and the lower half of the first chain 340 runs through the internal space of the crossbeam 311. A third slot 316 is provided in the middle of the bottom surface of the crossbeam 311, and the third slot 316 communicates with the internal space of the crossbeam 311. The positioning member 350 is detachably and spaced apart on the outer surface of the first chain 340, and the positioning member 350 is provided with a transport space for placing pipe materials.
[0019] The crossbeam 311 provides an installation position for the chain, the first sprocket 320, and the second sprocket 330. The first column 312 and the second column 313 provide stable support for the crossbeam 311, ensuring the stability of the entire feeding assembly 300 structure. The drive assembly 100 is connected to the synchronous shaft 200 through transmission, driving the synchronous shaft 200 to rotate, thereby driving the sprocket to rotate. The chain is wound between the first sprocket 320 and the second sprocket 330. The rotation of the sprocket drives the chain to circulate, realizing the dragging and conveying of the pipe material. The positioning component 350 provides a transportation space for the pipe material, ensuring that the pipe material can be stably placed on the chain and moved and conveyed on the feeding rack as the chain moves. The first slot 314 and the second slot 315 provide rotation space for the sprocket, making the sprocket and chain work together more smoothly. The third slot 316 connects to the internal space of the crossbeam 311, facilitating the installation and maintenance of the internal structure of the crossbeam 311 and improving maintenance efficiency. The third slot 316 on the crossbeam 311 not only facilitates the operation of the internal structure, but also reduces the overall weight of the frame 310, making the overall structure of the loading rack more reasonable and lightweight.
[0020] During operation, the drive assembly 100 drives the synchronous shaft 200 to rotate, and the synchronous shaft 200 drives the second sprocket 330 in each feeding assembly 300 to rotate. Since the first chain 340 is wound between the first sprocket 320 and the second sprocket 330, the rotation of the second sprocket 330 causes the chain to start circulating. The positioning members 350, which are spaced apart on the outer surface of the chain, move with the chain. The pipe material placed in the transport space of the positioning member 350 will be dragged along the conveying direction of the crossbeam 311, thereby realizing the conveying of the pipe material from one end of the feeding rack to the other end, and completing the feeding process.
[0021] Under heavy pipe loads or during prolonged use, the crossbeam 311 may experience structural deformation due to uneven stress or insufficient support caused by the third slot 316. Therefore, in one embodiment, the frame 310 further includes a reinforcing column 317, which is disposed between the first column 312 and the second column 313. The top of the reinforcing column 317 is fixedly connected to the bottom surface of the crossbeam 311, and the top of the reinforcing column 317 has a notch 318 that mates with the third slot 316. The reinforcing column 317 is positioned between the first column 312 and the second column 313, with its top end fixed to the bottom surface of the crossbeam 311. This enhances the structural strength of the frame 310, making it more stable when bearing heavy loads such as pipes. This reduces the probability of structural deformation due to excessive load and ensures a smooth and reliable feeding process. The top of the reinforcing column 317 has a notch 318 that mates with the third slot 316. This notch does not affect the original function of the third slot 316, which facilitates the installation and maintenance of the internal structure of the crossbeam 311 and reduces the overall weight of the frame 310. Instead, it allows the column to better support the crossbeam 311, further optimizing the overall structural rationality of the frame 310.
[0022] Each feeding component 300 is relatively independent and is prone to shaking and deformation during operation due to uneven forces such as pipe load and chain tension. Therefore, in one embodiment, the feeding rack also includes multiple connecting rods 400, which connect and fix adjacent second columns 313. The connecting rods 400 connect adjacent second columns 313, making the connection between the various parts of the entire feeding rack closer and forming a more stable overall structure. This effectively enhances the overall structural stability of the feeding rack and reduces shaking and displacement caused by external factors or its own operation.
[0023] When the tubing is conveyed on the chain, it may shift left or right due to factors such as vibration and inertia during the chain's movement. Therefore, in one embodiment, each set of the positioning members 350 includes two limiting blocks 351. The two limiting blocks 351 are detachably and spaced apart on the outer surface of the first chain 340, and the two limiting blocks 351 and the outer surface of the first chain 340 enclose the transport space. Two detachable limit blocks 351 are detachably spaced on the outer surface of the first chain 340, forming a transport space with the outer surface of the first chain 340. This provides good lateral limiting for the pipe material, effectively preventing lateral deviation during transport as the pipe material moves with the chain. This ensures that the pipe material is accurately transported to the designated position along the predetermined transport direction, improving the accuracy of feeding and ensuring smooth connection to subsequent processing stages. The detachable structure allows for flexible adjustment of the distance between the two limit blocks 351 according to the actual pipe diameter, thereby adjusting the width of the transport space to accommodate pipe materials of different diameters. This enhances the compatibility of the feeding rack with various pipe specifications, improving the versatility and efficiency of the equipment.
[0024] When the width of the transport space needs to be adjusted according to different pipe diameters and materials, it may be necessary to use complex tools or damage the original connection structure to make the adjustment. Therefore, in one embodiment, the first chain 340 includes multiple chain links 341 and multiple L-shaped connectors 342. The multiple chain links 341 are connected end to end. The two ends of the sidewall of the L-shaped connector 342 are respectively hinged to two adjacent chain links 341. The top of the L-shaped connector 342 is provided with a first mounting hole 343. The bottom surface of the limiting block 351 is provided with a second mounting hole 344 that mates with the first mounting hole 343. The limiting block 351 is detachably mounted on the L-shaped connector 342 by a first bolt, which passes through the first mounting hole 343 and the second mounting hole 344.
[0025] The different feeding components 300 may operate asynchronously due to different power sources or differences in power transmission, causing jamming, collisions, and other issues during the conveying of the pipe material. Therefore, in one embodiment, the drive component 100 includes a first motor 110, a drive wheel 120, a second chain 130, and a driven wheel 140. The first motor 110 is mounted on a second column 313. The drive wheel 120 is coaxially rotatable with the drive unit of the first motor 110. The drive wheel 120 is connected to the driven wheel 140 via the second chain 130. The driven wheel 140 is coaxially rotatable with one of the synchronous shafts 200. The first motor 110 drives the drive wheel 120 to rotate, and the drive wheel 120 drives the driven wheel 140 to rotate via the second chain 130. The driven wheel 140 rotates coaxially with the synchronous shaft 200. Power can be transmitted from the first motor 110 to the synchronous shaft 200 in sequence, and then to each feeding assembly 300, so as to realize the synchronous drive of multiple feeding assemblies 300, ensure the coordinated operation of the chain and other components in each feeding assembly 300, ensure the synchronicity and stability of the pipe material conveying, and avoid problems such as pipe material jamming caused by asynchrony.
[0026] Without accurately knowing the real-time position of the pipe material during the conveying process, it is difficult to achieve precise control over the start and stop of the pipe material, which may result in the pipe material being conveyed incompletely or exceeding the designated position, affecting the connection of subsequent processing steps. Therefore, in one embodiment, the loading rack also includes a mounting plate 500, a sensor, and multiple sensing plates 510. The mounting plate 500 is disposed on the crossbeam 311, the sensor is disposed on the mounting plate 500, and the sensing plates 510 are disposed one-to-one at the bottom of the positioning member 350. The sensor is used to sense the sensing plates 510. By sensing the corresponding sensing plate 510 set at the bottom of the positioning component 350, the position of the positioning component 350 can be monitored in real time. Since the positioning component 350 carries the pipe material, the position of the pipe material is indirectly accurately controlled. The start and stop of the pipe material during the conveying process can be precisely controlled. When the pipe material reaches the designated position, the sensor detects the corresponding sensing plate 510 and sends a signal to the drive component 100 to stop working in time, so that the pipe material stops accurately in the required position. It can also count the conveyed pipe material to clearly understand how many pipe materials have been conveyed, thereby better controlling the entire feeding process and improving the accuracy and efficiency of feeding.
[0027] When changes in production processes or pipe specifications necessitate altering the sensor's detection position, the sensor may not be easily repositioned. Therefore, in one embodiment, the mounting plate 500 is provided with a slot 501, which engages with bolts to fix the sensor to the mounting plate 500. By providing the slot 501 on the mounting plate 500 and allowing bolts to pass through it to fix the sensor, the sensor is not fixed in a static position on the mounting plate 500. It can be moved and adjusted within a certain range along the length of the slot 501. This allows the sensor to be easily adjusted according to various diverse needs, ensuring accurate detection of the sensing element 510 at all times. This enables precise and effective control of the pipe conveying process, meeting the requirements of various production conditions and improving the overall applicability and practicality of the feeding rack.
