Description

Technical Field

[0001] This utility model relates to the field of tubular processing technology, specifically to a tubular feeding device. Background Technology

[0002] Tube processing is a fundamental and critical process in many industries such as petroleum, chemical, construction, and machinery manufacturing. Its processing quality and efficiency directly affect the performance of subsequent products and production progress. As the starting step of the tube processing process, the stability and automation level of the feeding process play a decisive role in the overall production effect.

[0003] In existing tubular feeding equipment, box-type hoppers are a common feeding carrier. Their working principle mainly relies on the lifting mechanism to apply an upward lifting force to the tubular columns inside the hopper, causing the tubular columns to be discharged from the hopper outlet and enter the subsequent processing stage. However, in actual operation, the tubular column discharge state exhibits a high degree of randomness, often resulting in two extreme situations: On the one hand, some tubular columns may become stuck due to insufficient lifting force, excessive friction between tubular columns, or slight blockage at the hopper outlet, preventing them from being discharged smoothly from the hopper. In this case, manual intervention is required, stopping the machine to clear or adjust the stuck position. This not only interrupts the continuous processing flow but also increases the intensity and frequency of manual operation. On the other hand, sometimes excessive lifting force or unstable tubular column arrangement can cause multiple tubular columns to surge out of the hopper outlet simultaneously, resulting in a large number of tubular columns accumulating instantly at subsequent conveying or processing stations, causing process blockage. This not only disrupts the normal processing rhythm but may also cause scratches, deformation, and other damage to the tubular column surface due to mutual collision and compression, affecting the processing accuracy of the tubular columns and product quality.

[0004] Based on this, the present invention designs a tube column feeding device to solve the above problems. Utility Model Content

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] The present invention will be further described below with reference to the embodiments.

[0035] In some embodiments, please refer to the appendix to the instruction manual. Figure 1 - Figure 3 A tube column feeding device includes a support 1, a feeding mechanism 2 fixedly connected to the upper end of the support 1, a release mechanism 3 fixedly connected to the upper end of the support 1, a processing and conveying mechanism 4 fixedly connected to the upper end of the support 1, and a transfer box 5 fixedly connected to the upper end of the support 1. The feeding mechanism 2 includes a feeding box 21, which is fixedly installed on the upper end of the support 1. An inclined plate 22 is fixedly connected to the inner cavity of the feeding box 21, and a feeding assembly 23 is fixedly connected to the inner cavity of the feeding box 21. Multiple tube column bodies 24 are filled inside the feeding box 21.

[0036] The support frame 1, which serves as the foundation for the entire device, is made of Q235 low-carbon steel and can stably bear the total weight of the feeding mechanism 2, the release mechanism 3, the processing and conveying mechanism 4, and the tube column body 24. The transfer box 5 is made of 304 stainless steel and is fixed on the upper end of the support frame 1 near the outlet of the processing and conveying mechanism 4. It is used to temporarily store the processed tube column and provide transition space for the tube column to be transferred to the next section.

[0037] The feeding assembly 23 includes a support frame 231, which is fixedly installed on one side of the feeding box 21. A motor 232 is fixedly connected to the upper end of the support frame 231. A drive roller 233 is fixedly connected to the output end of the motor 232 through a coupling. A conveyor belt 234 is meshed with the outer surface of the drive roller 233. Multiple support rollers 235 are meshed with the inner surface of the conveyor belt 234. The support rollers 235 are fixedly installed in the inner cavity of the feeding box 21 and the inner wall of the bracket 1. Multiple rubber strips 236 are fixedly connected to the outer surface of the conveyor belt 234.

[0038] Motor 232 is a three-phase asynchronous motor, whose speed can be adjusted according to the feeding requirements, providing continuous and stable power for the operation of conveyor belt 234. Drive roller 233 is rigidly connected to the output end of motor 232 through a coupling, responsible for driving the conveyor belt 234 to rotate. Support rollers 235 are evenly distributed on the inner side of conveyor belt 234 to support the weight of conveyor belt 234 and tube column, preventing the conveyor belt 234 from sagging due to force and causing the conveying trajectory to deviate. Conveyor belt 234 is made of polyurethane, which has high strength, high elasticity and wear resistance, and can adapt to long-term high-frequency tube column conveying work. The rubber strips 236 fixed at intervals on its outer surface are made of nitrile rubber, which has good anti-slip performance. The distance between adjacent rubber strips 236 matches the diameter of the tube column, which can form individual separation and constraint of the tube column, ensuring that the tube column is conveyed in a single form, which can solve the problems of material jamming or multiple raw materials being discharged at the same time in traditional feeding.

[0039] In this embodiment of the present invention, the tube body 24 to be processed is placed into the feeding box 21 of the feeding mechanism 2. Under its own gravity, the tube body 24 slides along the inclined plate 22 inside the feeding box 21 toward the feeding assembly 23 and finally falls onto the conveyor belt 234. The motor 232 of the feeding assembly 23 is started. The motor 232 drives the drive roller 233 to rotate through the coupling. The drive roller 233 further drives the conveyor belt 234 to move along the support roller 235. Whenever the rubber strip 236 on the outer surface of the conveyor belt 234 passes through the inclined plate 22, it will carry away one tube body 24, so that the tube body 24 can be transported to the release mechanism 3 under the action of the conveyor belt 234. During this process, the two adjacent rubber strips 236 will separate and constrain the tube body 24, ensuring that the tube body 24 can be transported to the release mechanism 3 in a single form with the conveyor belt 234.

[0040] In some embodiments, such as Figure 4 - Figure 5 As shown, in a preferred embodiment of the present invention, the release mechanism 3 includes two side baffles 31, both of which are fixedly installed on the upper end of the bracket 1 and on one side of the feeding box 21. The inner walls of the two side baffles 31 are fixedly connected to slide rails 32. The cabinet at the end of the two side baffles 31 that are close to each other is fixedly connected to a receiving platform 33. The upper end of the receiving platform 33 is provided with an installation groove 34. The inner cavity of the installation groove 34 is fixedly connected to an ejection component 35. The upper end of the receiving platform 33 is fixedly connected to a stop block 36.

[0041] The ejection assembly 35 includes a support block 351 and a magnetic plate 353. The support block 351 is fixedly installed in the inner cavity of the mounting groove 34. An electromagnet 352 is fixedly connected to the upper end of the support block 351. An ejection plate 354 is fixedly connected to the upper end of the magnetic plate 353. Slider 355 is fixedly connected to both sides of the ejection plate 354. Multiple springs 356 are fixedly connected to the lower end of the ejection plate 354. The lower ends of the multiple springs 356 are fixedly installed on the bottom wall of the inner cavity of the mounting groove 34. The outer surfaces of the two sliders 355 are slidably connected to the outer surfaces of the two slide rails 32, respectively.

[0042] Electromagnet 352 is a DC electromagnet. When energized, it generates magnetic force to repel magnetic plate 353. When de-energized, the magnetic force disappears, and magnetic plate 353 is reset by spring 356. The ejector plate 354 is made of 304 stainless steel. Its upper end is a gentle slope that matches the slope of the receiving platform 33, which facilitates the tube column to slide down the slope. The stop block 36 is made of polyurethane and is fixed to the end of the receiving platform 33 away from the feeding box 21. It is used to limit the end of the tube column and prevent the tube column from sliding excessively.

[0043] In this embodiment of the utility model, when the tube column body 24 comes into contact with the receiving platform 33 under the drive of the conveyor belt 234, the tube column body 24 will roll along the receiving platform 33. When the tube column body 24 rolls to the side of the stop block 36, it will stop moving under the action of the stop block 36. At this time, the foremost tube column body 24 is just located at the top of the ejector plate 354, and the subsequent tube column bodies 24 will be arranged sequentially along the surface of the receiving platform 33.

[0044] When the column body 24 needs to be released to the processing and conveying mechanism 4, the electromagnet 352 of the control ejection assembly 35 is energized, so that the electromagnet 352 generates a repulsive force to repel the magnetic plate 353, so that the magnetic plate 353 can drive the ejection plate 354 to move upward along the slide rail 32 with the cooperation of the two sliders 355. At this time, the spring 356 is in a stretched state. When the ejection plate 354 rises, it will lift the column body 24 located above it, making it higher than the stop block 36. At this time, the column body 24 will roll down the inclined surface of the ejection plate 354 and roll into the processing and conveying mechanism 4 along the stop block 36.

[0045] In some embodiments, such as Figure 6 - Figure 9 As shown, in a preferred embodiment of the present invention, the processing and conveying mechanism 4 includes two side baffles 41. Both side baffles 41 are fixedly installed on the upper end of the bracket 1. Both side baffles 41 are fixedly installed on one side of the side baffle 31. The ends of the two side baffles 41 that are far apart from each other are fixedly connected to a thread cutting machine 42. The ends of the two side baffles 41 that are close to each other are fixedly connected to a fixing component 43. A wedge block 44 is fixedly connected to the upper part of the fixing component 43. A feeding component 45 is fixedly connected to the upper end of the two side baffles 41. A conveying component 46 is fixedly connected to the lower part of the fixing component 43.

[0046] The fixing component 43 includes a U-shaped platform 431, which is fixedly installed between two side baffles 41. Two guide blocks 432 are fixedly connected to the inner wall of the U-shaped platform 431, and two slide grooves 433 are fixedly connected to the inner wall of the U-shaped platform 431. A pair of slide rails 434 are fixedly connected to the inner wall of each slide groove 433. Electric push rods 435 are fixedly connected to both sides of the U-shaped platform 431. Clamping plates 436 are fixedly connected to the output ends of the two electric push rods 435. The inner surfaces of the two clamping plates 436 are slidably connected to the outer surfaces of the two pairs of slide rails 434, and rubber pads 437 are fixedly connected to the ends of the two clamping plates 436 that are close to each other.

[0047] The guide block 432 is made of polyurethane and is symmetrically fixed to the inner wall of the entrance end of the U-shaped stage 431. Its inclined surface can guide the tube column to enter the processing position accurately and avoid the tube column from hitting the inner wall of the U-shaped stage 431. The electric push rod 435 is a ball screw type electric push rod, which can push the clamping plate 436 to clamp and release the tube column. The rubber pad 437 is made of nitrile rubber, which can not only enhance the friction between the tube column and the clamping plate 436 to prevent the tube column from sliding during processing, but also prevent excessive clamping force from damaging the surface of the tube column through elastic buffering.

[0048] The conveying assembly 46 includes a hydraulic cylinder 461, which is fixedly installed at the lower end of the U-shaped platform 431. The output end of the hydraulic cylinder 461 is fixedly connected to a material placement plate 462. Two negative pressure pumps 463 are fixedly connected to the lower end of the material placement plate 462. Multiple air holes 465 are opened at the upper end of the material placement plate 462. A rubber pad 464 is fixedly connected to the inner surface of the material placement plate 462.

[0049] Hydraulic cylinder 461 is a carbon steel cylinder with a hydraulic push rod, which can control the lifting and lowering of the material plate 462. The air hole 465 at the upper end of the material plate 462 is connected to the air passage of the negative pressure pump 463 to form a negative pressure adsorption structure. The negative pressure pump 463 is a vortex negative pressure pump, which generates negative pressure through the air hole 465, which can firmly adsorb the tube column onto the material plate 462. The rubber pad 464 is made of nitrile rubber and is fixed to the upper surface of the material plate 462. It can enhance the sealing between the tube column and the material plate 462, improve the negative pressure adsorption effect, and protect the surface of the tube column from damage.

[0050] The feeding assembly 45 includes two positioning plates 451. The lower ends of the two positioning plates 451 are respectively fixed to the upper ends of two side baffles 41. A support frame 452 is fixedly connected to one side of one positioning plate 451. A motor 453 is fixedly connected to the upper end of the support frame 452. The output end of the motor 453 is fixedly connected to the feeding plate 454.

[0051] Motor 453 is a stepper motor with a power supply voltage of 220VAC. It can drive the feed plate 454 to achieve quantitative rotation, ensuring the smooth pushing of the tube column. The feed plate 454 is made of nitrile rubber and is pushed away from the tube column by friction.

[0052] In this embodiment of the utility model, after the tubular body 24 rolls into the processing and conveying mechanism 4 along the stop block 36, it will roll into the U-shaped table 431 under the action of inertia and under the limit of the guide block 432, and fall above the material placement plate 462; at this time, the negative pressure pump 463 is started, and the negative pressure pump 463 generates negative pressure through the air hole 465 on the material placement plate 462, which firmly adsorbs the tubular body 24 onto the rubber pad 464 of the material placement plate 462.

[0053] Meanwhile, when the column body 24 reaches the preset processing position (above the material plate 462) in the U-shaped table 431, the electric push rods 435 on both sides are activated. The output end of the electric push rod 435 pushes the clamping plate 436 to move along the slide rail 434 in the slide groove 433 towards the column body 24 until the rubber pad 437 on the inner side of the clamping plate 436 is in close contact with the surface of the column body 24. The column body 24 is then clamped and fixed from both sides. At this time, the threading machines 42 on both sides are activated, and the threading machines 42 perform external threading and internal threading on both ends of the column body 24 according to the preset processing parameters. At the same time, other auxiliary equipment is used to complete the surface treatment process such as lubrication of the inner wall of the column.

[0054] After the tubular column body 24 is processed, the threading machine 42 is stopped, and the electric push rod 435 is reset. The electric push rod 435 drives the clamping plate 436 to move away from the tubular column, releasing the clamping and fixing of the tubular column body 24. The hydraulic cylinder 461 is started, which drives the material plate 462 and the processed tubular column body 24 to move upward. When the tubular column body 24 is within the range that the unloading assembly 45 can cover, the hydraulic cylinder 461 and the negative pressure pump 463 are stopped, and the second motor 453 is started. The second motor 453 drives the unloading plate 454 to rotate. When the unloading plate 454 rotates, it can push the tubular column body 24 away from the material plate 462, so that it slides out of the processing conveying mechanism 4 along the wedge block 44 and finally falls into the transfer box 5, waiting for the next process.

[0055] It should be noted that the second motor 453, electric push rod 435, thread cutting machine 42, negative pressure pump 463, electromagnet 352, hydraulic cylinder 461, and first motor 232 in this utility model are powered by a power source and controlled by a controller.

[0056] It should be noted that the specific installation methods, circuit connection methods, oil circuit connection methods, and control methods of the second motor 453, electric push rod 435, thread cutting machine 42, negative pressure pump 463, electromagnet 352, hydraulic cylinder 461, and first motor 232 in this utility model are all conventional designs, and this utility model will not elaborate on them in detail.

[0057] Working principle:

[0058] Feeding: The tube body 24 to be processed is placed into the feeding box 21 of the feeding mechanism 2. Under its own gravity, the tube body 24 slides along the inclined plate 22 inside the feeding box 21 toward the feeding assembly 23 and finally falls onto the conveyor belt 234. The motor 232 of the feeding assembly 23 is started. The motor 232 drives the drive roller 233 to rotate through the coupling. The drive roller 233 further drives the conveyor belt 234 to move along the support roller 235. Whenever the rubber strip 236 on the outer surface of the conveyor belt 234 passes through the inclined plate 22, it will carry away one tube body 24, so that the tube body 24 can be transported to the release mechanism 3 under the action of the conveyor belt 234. During this process, the two adjacent rubber strips 236 will separate and constrain the tube body 24, ensuring that the tube body 24 can be transported to the release mechanism 3 in a single form with the conveyor belt 234.

[0059] Single release: When the tube body 24 comes into contact with the receiving platform 33 under the drive of the conveyor belt 234, the tube body 24 will roll along the receiving platform 33. When the tube body 24 rolls to the side of the stop block 36, it will stop moving under the action of the stop block 36. At this time, the foremost tube body 24 is just located on the top of the ejector plate 354, and the subsequent tube bodies 24 will be arranged in sequence along the surface of the receiving platform 33.

[0060] When the column body 24 needs to be released to the processing and conveying mechanism 4, the electromagnet 352 of the control ejection assembly 35 is energized, so that the electromagnet 352 generates a repulsive force to repel the magnetic plate 353, so that the magnetic plate 353 can drive the ejection plate 354 to move upward along the slide rail 32 with the cooperation of the two sliders 355. At this time, the spring 356 is in a stretched state. When the ejection plate 354 rises, it will lift the column body 24 located above it, making it higher than the stop block 36. At this time, the column body 24 will roll down the inclined surface of the ejection plate 354 and roll into the processing and conveying mechanism 4 along the stop block 36.

[0061] After the single tube column body 24 is released, the control electromagnet 352 is de-energized. After the repulsive force disappears, the ejector plate 354 will reset under the action of the spring 356. After it resets, the next tube column body 24 will have space to continue rolling. It will roll along the surface of the receiving platform 33 to the side of the stop block 36 and will be located just above the ejector plate 354.

[0062] Positioning: After the tubular column body 24 rolls into the processing conveying mechanism 4 along the stop block 36, it will roll into the U-shaped table 431 under the action of inertia and under the limit of the guide block 432, and fall above the material placement plate 462; at this time, the negative pressure pump 463 is started, and the negative pressure pump 463 generates negative pressure through the air hole 465 on the material placement plate 462, which firmly adsorbs the tubular column body 24 onto the rubber pad 464 of the material placement plate 462.

[0063] Meanwhile, when the column body 24 reaches the preset processing position (above the material plate 462) in the U-shaped table 431, the electric push rods 435 on both sides are activated. The output end of the electric push rod 435 pushes the clamping plate 436 to move along the slide rail 434 in the slide groove 433 towards the column body 24 until the rubber pad 437 on the inner side of the clamping plate 436 is in close contact with the surface of the column body 24. The column body 24 is then clamped and fixed from both sides. At this time, the threading machines 42 on both sides are activated, and the threading machines 42 perform external threading and internal threading on both ends of the column body 24 according to the preset processing parameters. At the same time, other auxiliary equipment is used to complete the surface treatment process such as lubrication of the inner wall of the column.

[0064] Material feeding: After the tubular column body 24 is processed, the threading machine 42 is stopped and the electric push rod 435 is reset. The electric push rod 435 drives the clamping plate 436 to move away from the tubular column, releasing the clamping and fixing of the tubular column body 24. The hydraulic cylinder 461 is started, which drives the material placement plate 462 and the processed tubular column body 24 to move upward. When the tubular column body 24 is within the range that the feeding component 45 can cover, the hydraulic cylinder 461 and the negative pressure pump 463 are stopped and the second motor 453 is started. The second motor 453 drives the feeding plate 454 to rotate. When the feeding plate 454 rotates, it can push the tubular column body 24 away from the material placement plate 462, so that it slides out of the processing conveying mechanism 4 along the wedge block 44 and finally falls into the transfer box 5, waiting for the next process.
