Description

Technical Field

[0001] The invention belongs to the technical field of feeding devices, and in particular relates to a feeding device for steel structure processing. Background Art

[0002] Steel structure is a building load-bearing system made of steel (such as steel sections, steel plates, etc.) as the main material through welding, bolting, etc. It has the advantages of high strength, fast construction, environmental protection and recyclability. It is widely used in factories, bridges, super high-rise buildings and other fields.

[0003] When processing steel structures, due to the large size and heavy weight of raw materials, manual handling is inefficient and poses safety risks. Therefore, loading devices (such as roller conveyors, gantry cranes or robots) are required to complete automated loading and accurately transport the steel to cutting, welding and other processing equipment to ensure an efficient, accurate and safe production process.

[0004] In the use of roller conveyors, it was found that if pure metal conveyor rollers are used to complete the conveying work, the conveyor rollers are prone to slipping and will cause wear to the raw materials. If rubber sleeves are installed on the outer wall of the conveyor rollers, these problems can be solved. However, after long-term use, the rubber sleeves are prone to heat and wear, resulting in more frequent maintenance of the conveyor rollers and higher costs. Summary of the Invention

When the strip frame moves downward, the pushing part drives the conveying roller to slide along the outer wall of the polygonal guide rod.

[0010] Furthermore, the pushing part includes a second reciprocating screw rotatably connected to the outer wall of the strip frame, a reciprocating push plate is installed on the outer wall of the second reciprocating screw, a driven gear is installed on the shaft end of the conveying roller through a one-way bearing, a rack meshing with the driven gear is fixedly installed in the protective cover, and a circular ring is fixedly connected to the end of the reciprocating push plate, and the circular ring is rotatably connected to the shaft end of the conveying roller.

[0011] Preferably, an air suction hood is provided at the inner bottom of the protective cover, the air suction end of the air suction hood faces the lower part of the conveying roller, and one end of the air suction hood is rotatably connected to an exhaust pipe communicating therewith.

[0012] Furthermore, the bottom of the protective cover is fixedly connected to a vertical tube, a support rod is longitudinally slidably installed in the vertical tube, a spring is installed between the support rod and the bottom of the vertical tube, the air suction hood is fixedly connected to the top of the support rod, and the side wall of the air suction hood is fixedly connected to a top pressure plate, and when the L-shaped frame moves downward, the L-shaped frame will press on the top pressure plate.

[0014] Furthermore, fan blades are fixedly installed on the inner wall of the exhaust end of the exhaust pipe, and the other end of the exhaust pipe and the outer wall of the rotating shaft are fixedly connected to transmission wheels.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0018] 1. The present invention uses two continuously rotating incomplete gears to take turns lowering the two groups of bar racks and then resetting them upward, so that the two groups of conveyor rollers can take turns to load the steel structure raw materials, thereby reducing the working intensity of the conveyor rollers. The rubber sleeves on the outer walls of the conveyor rollers are not prone to heat and wear, thereby reducing the number of maintenance and maintenance costs.

In this way, after the conveyor roller is reset upward, it can prevent the conveyor roller from excessively concentrating on contacting and rubbing against the steel structure raw material on a certain outer wall. In this way, the rubber sleeve on the outer wall of the conveyor roller is not easy to wear and heat up, further reducing the number of maintenance times and costs.

[0020] 3. The present invention drives the conveying roller close to the upper port of the suction hood through the downward moving strip frame, and also drives the transmission wheel to press on another transmission wheel. The exhaust pipe will suck air into the suction hood through the suction hole. The suction hood will absorb the dust adhering to the outer wall of the rubber sleeve, and can also dissipate heat for the conveying roller and the rubber sleeve, so that the rubber sleeve on the outer wall of the conveying roller is not easy to slip, thereby maintaining good conveying accuracy.

[0021] 4. In the present invention, after the conveying roller is close to the upper port of the suction hood, the brush on the outer wall of the exhaust pipe will contact the outer wall of the conveying roller, thereby more efficiently cleaning the dust on the outer wall of the rubber sleeve, and the reciprocating conveying roller will make the rubber sleeve slide back and forth on the brush, thereby making the brush more efficient in cleaning the dust on the outer wall of the rubber sleeve, and the reciprocating conveying roller can be in more sufficient contact with the flowing air, thereby enabling the conveying roller and the rubber sleeve to obtain better heat dissipation.

[0033] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0034] Example 1: Reference Figures 1-8A feeding device for steel structure processing includes a protective cover 1 with a strip groove 2 on the top. The steel structure raw materials to be transported need to be in the strip groove 2. The steel structure raw materials are mainly long strips of I-beams or steel plates. It also includes: two groups of symmetrically arranged strip racks 3, both of which are longitudinally slidably installed in the protective cover 1 and are arranged parallel to the strip groove 2. Among them, the two groups of strip racks 3 are rotatably installed with a rotating shaft 7. The outer wall of each rotating shaft 7 is installed with a conveying roller 5 for conveying the steel structure raw materials. The middle part of the conveying roller 5 is exposed in the strip groove 2. A set of conveying rollers 5 is located in the gap of the other set of conveying rollers 5. A driving source 9 for driving the rotating shaft 7 is fixedly installed on the strip frame 3. The driving source 9 is mainly composed of a servo motor and a gear set. The gear set is used to make all the rotating shafts 7 rotate synchronously; two symmetrically arranged lifting frames 15 are fixedly connected to the two strip frames 3 respectively. The protective cover 1 is provided with a lifting part that drives the two lifting frames 15 to rise and fall in turn. The outer wall fixed sleeve of the conveying roller 5 is provided with a rubber sleeve 6, and the outer wall of the rubber sleeve 6 is provided with anti-slip grooves 4 for improving the anti-slip performance.

[0035] Specifically, when in use, the driving source 9 can drive the conveyor roller 5 to rotate continuously to realize the conveying of steel structure raw materials. During this period, the lifting part can take turns to lower the two groups of bar frames 3 and reset them upward, so that the two groups of conveyor rollers 5 can take turns to realize the loading of steel structure raw materials, thereby reducing the working intensity of the conveyor roller 5, and the rubber sleeve 6 on the outer wall of the conveyor roller 5 is not easy to heat up and wear, so the maintenance frequency and maintenance cost can be reduced. After the conveyor roller 5 is lowered, the rotating conveyor roller 5 can also shake off the dust on the outer wall, so that the conveyor roller 5 is not easy to slip, maintain a high loading efficiency and transmission accuracy, and can fully contact with the air to obtain efficient heat dissipation.

[0036] Example 2: Reference Figure 3-Figure 4 , a feeding device for steel structure processing, which is basically the same as Example 1, further comprising:

[0037] The above-mentioned lifting part includes two first reciprocating screws 11 rotatably connected to the protective cover 1, and the two strip frames 3 are respectively connected to the outer walls of the two first reciprocating screws 11. At this time, the strip frame 3 is equivalent to a slide on the outer wall of the first reciprocating screw 11. When the first reciprocating screw 11 continues to rotate, it can drive the strip frame 3 to slide back and forth along the outer wall of the first reciprocating screw 11. A passive gear 13 is fixedly installed on the top of the two first reciprocating screws 11; a drive motor 12 is fixedly installed on the protective cover 1, and two incomplete gears 14 are fixedly installed on the output shaft of the drive motor 12. When one of the incomplete gears 14 is engaged with one of the passive gears 13, the other incomplete gear 14 is not engaged with the other passive gear 13, and the teeth of the incomplete gear 14 are only half or less than half.

[0038] Specifically, during the feeding of the conveying roller 5, the driving motor 12 drives the two incomplete gears 14 to rotate synchronously. When one of the incomplete gears 14 is meshed with one of the driven gears 13 for transmission, the current driven gear 13 drives the first reciprocating screw 11 connected thereto to rotate. The first reciprocating screw 11 drives the lifting frame 15 on its outer wall to move downward and then lifts it upward to reset. During the descent of the lifting frame 15, it drives the strip frame 3 connected thereto to move downward, and the strip frame 3 drives a group of conveying rollers 5 connected thereto to move downward. At this time, the conveying rollers 5 on the other group of strip frames 3 continue to complete the conveying of the steel structure raw materials. After the current strip frame 3 is lifted up and reset, the other incomplete gear 14 will mesh with the other passive gear 13 for transmission, so the other first reciprocating screw 11 will drive the other set of strip frames 3 and conveying rollers 5 to descend and reset upward through another lifting frame 15, so the two continuously rotating incomplete gears 14 will take turns to make the two sets of strip frames 3 descend and reset upward, so that the two sets of conveying rollers 5 can take turns to realize the feeding work of steel structure raw materials, thereby reducing the working intensity of the conveying rollers 5, and the rubber sleeve 6 on the outer wall of the conveying roller 5 is not easy to heat up and wear, so the maintenance frequency and maintenance cost can be reduced.

[0039] In another embodiment, if the steel structure raw material being transported is heavy and the first reciprocating screw 11 is unable to bear the weight, the first reciprocating screw 11 used to realize the lifting and lowering of the two strip frames 3 can be replaced by a hydraulic cylinder. The hydraulic cylinder needs to be fixedly installed on the protective cover 1, and the telescopic end of the hydraulic cylinder is fixed to the lifting frame 15 or the strip frame 3, so that the hydraulic cylinder can also realize the alternating raising and lowering of the strip frames 3.

[0040] Example 3: Reference Figure 5-Figure 8 , a feeding device for steel structure processing, which is basically the same as Example 2, further comprising:

[0041] The above-mentioned strip frame 3 is fixedly connected to an L-shaped frame 10, one end of the rotating shaft 7 is rotatably mounted on the L-shaped frame 10, and the outer wall of the rotating shaft 7 is fixedly connected to a polygonal guide rod 8, the axial cross-section of the polygonal guide rod 8 is polygonal, for example, a regular hexagon, and the conveying roller 5 is laterally slidably sleeved on the outer wall of the polygonal guide rod 8, and a pushing portion is provided on the strip frame 3. When the strip frame 3 moves downward, the pushing portion drives the conveying roller 5 to slide along the outer wall of the polygonal guide rod 8, and the pushing portion includes a second reciprocating screw 16 rotatably connected to the outer wall of the strip frame 3. A reciprocating push plate 18 is installed on the outer wall of the second reciprocating screw 16, and a driven gear 20 is installed on the shaft end of the conveying roller 5 through a one-way bearing. A rack 19 meshing with the driven gear 20 is fixedly installed in the protective cover 1, and the end of the reciprocating push plate 18 is fixedly connected to a ring 17, which is rotatably connected to the shaft end of the conveying roller 5.

[0042] Specifically, when the strip frame 3 drives the conveying roller 5 to move downward, the strip frame 3 will also drive the driven gear 20 to sweep across the rack 19, and the rack 19 will drive the driven gear 20 to rotate, and the driven gear 20 will drive the second reciprocating screw 16 to rotate, and the second reciprocating screw 16 will drive the reciprocating push plate 18 to slide back and forth, and the reciprocating push plate 18 will drive the conveying roller 5 to slide back and forth on the outer wall of the polygonal guide rod 8 through the ring 17, and the position where the conveying roller 5 finally stops sliding does not overlap with the previous position, so that the conveying roller 5 can be reciprocated upward. After being in position, it can prevent the conveyor roller 5 from excessively concentrating on using a certain part of the outer wall to contact and rub against the steel structure material, so that the rubber sleeve 6 on the outer wall of the conveyor roller 5 is not easy to wear and heat up, further reducing the number of maintenance times and costs. When the bar frame 3 drives the driven gear 20 to move upward and reset, the rack 19 will drive the driven gear 20 to reverse. Since the driven gear 20 is installed on the shaft end of the second reciprocating screw 16 through a one-way bearing, the driven gear 20 will only idle instead of driving the second reciprocating screw 16 to reverse and reset.

[0043] Example 4: Reference Figure 2-Figure 6 as well as Figure 8 , a feeding device for steel structure processing, which is basically the same as Example 3, further comprising:

[0044] An air suction hood 21 is provided at the inner bottom of the protective cover 1 , with the air suction end of the air suction hood 21 facing the lower part of the conveying roller 5 , and one end of the air suction hood 21 is rotatably connected to an exhaust pipe 26 communicating therewith.

[0045] Specifically, when the strip frame 3 moves downward, the conveying roller 5 will be close to the upper port of the suction hood 21. At this time, the exhaust pipe 26 will be sucked in by the fan, and the exhaust pipe 26 will suck in the conveying roller 5 through the suction hood 21, thereby absorbing the dust on the outer wall of the rubber sleeve 6 and dissipating the heat of the rubber sleeve 6 and the conveying roller 5. The rubber sleeve 6 on the outer wall of the conveying roller 5 is not easy to slip, and good conveying accuracy is maintained.

[0046] The bottom of the above-mentioned protective cover 1 is fixedly connected to a vertical pipe 23, and a support rod 24 is longitudinally slidably installed in the vertical pipe 23. A spring 25 is installed between the support rod 24 and the bottom of the vertical pipe 23. The air suction hood 21 is fixedly connected to the top of the support rod 24, and the side wall of the air suction hood 21 is fixedly connected to a top pressure plate 22. When the L-shaped frame 10 moves downward, the L-shaped frame 10 will press on the top pressure plate 22.

[0047] Specifically, when the strip frame 3 moves downward, the conveying roller 5 will be close to the upper port of the air suction hood 21, and will also drive the L-shaped frame 10 to move downward. The L-shaped frame 10 will push the top pressure plate 22 to move downward, and the top pressure plate 22 will drive the air suction hood 21 to move downward synchronously, so as to maintain a fixed distance between the air suction hood 21 and the conveying roller 5, so that the air suction hood 21 can efficiently remove dust and dissipate heat for the conveying roller 5. When the air suction hood 21 moves downward, the air suction hood 21 will also drive the support rod 24 to slide toward the inner bottom direction of the vertical pipe 23 and compress the spring 25. After the strip frame 3 drives the L-shaped frame 10 to reset upward, the top pressure plate 22 is no longer subjected to the top pressure of the L-shaped frame 10. At this time, the spring 25 will elastically reset and drive the air suction hood 21 to move upward and reset through the support rod 24.

[0048] The air intake end of the exhaust pipe 26 extends into the air intake hood 21 . An air intake hole 28 located in the air intake hood 21 is provided on the outer wall of the exhaust pipe 26 . A brush 29 is fixedly provided on the outer wall of the exhaust pipe 26 near the air intake hole 28 .

[0049] Specifically, the exhaust pipe 26 is of suction type, and the exhaust pipe 26 will suck air into the suction hood 21 through the suction hole 28, and the suction hood 21 will absorb the dust adhering to the outer wall of the rubber sleeve 6, and the reciprocating conveying roller 5 will make the rubber sleeve 6 slide back and forth on the brush 29, so that the brush 29 can clean the dust on the outer wall of the rubber sleeve 6 more efficiently, and the reciprocating conveying roller 5 can be in more full contact with the flowing air, thereby enabling the conveying roller 5 and the rubber sleeve 6 to obtain better heat dissipation.

[0050] A fan blade 27 is fixedly installed on the inner wall of the exhaust end of the above-mentioned exhaust pipe 26, and a transmission wheel 30 is fixedly connected to the other end of the exhaust pipe 26 and the outer wall of the rotating shaft 7. When the rotating shaft 7 moves downward, the transmission wheel 30 on the rotating shaft 7 will fit into another transmission wheel 30. The transmission wheel 30 can be a spur gear or a disc made of rubber material, and power can be transmitted between the two through friction.

[0051] Specifically, when the strip frame 3 moves downward, the downward moving strip frame 3 will also drive the transmission wheel 30 to press on another transmission wheel 30, and the rotating shaft 7 will drive the exhaust pipe 26 to rotate through the two mutually fitting transmission wheels 30, and the exhaust pipe 26 will drive the internal fan blades 27 to rotate, and the exhaust pipe 26 will suck air into the suction hood 21 through the suction hole 28, so the exhaust end of the exhaust pipe 26 can be without an external fan equipment, and the power of the downward moving unloaded conveying roller 5 can be well utilized, reducing the waste of resources.

[0052] An air collecting cover 31 is longitudinally slidably mounted on the inner wall of the protective cover 1 . An air outlet 32 extending to the lower end of the protective cover 1 is provided at the lower end of the air collecting cover 31 . The exhaust end of the exhaust pipe 26 extends into the air collecting cover 31 .

[0053] Specifically, when the exhaust pipe 26 discharges the internal air and dust, the air and dust will be discharged into the air collecting hood 31 and finally discharged from the exhaust port 32, thereby facilitating the subsequent centralized treatment of the dust and hot air.

[0054] When the present invention is in use, the driving source 9 can drive the conveying roller 5 to rotate continuously to realize the conveying of steel structure raw materials. During this period, the driving motor 12 will drive the two incomplete gears 14 to rotate synchronously. When one of the incomplete gears 14 is meshed with one of the driven gears 13 for transmission, the current driven gear 13 will drive the first reciprocating screw 11 connected thereto to rotate. The first reciprocating screw 11 will drive the lifting frame 15 of its outer wall to move downward and then lift it up and reset. During the descent of the lifting frame 15, it will drive the strip frame 3 connected thereto to move downward, and the strip frame 3 will drive a group of conveying rollers 5 connected thereto to move downward. At this time, the conveying rollers 5 on the other group of strip frames 3 continue to complete the conveying of the steel structure raw materials. After the current strip frame 3 is lifted upward and reset, Another incomplete gear 14 will mesh with another passive gear 13 for transmission, so that another first reciprocating screw 11 will drive another set of strip frames 3 and conveyor rollers 5 to descend and reset upward through another lifting frame 15, so that the two continuously rotating incomplete gears 14 will take turns to descend and reset the two sets of strip frames 3, so that the two sets of conveyor rollers 5 can take turns to load the steel structure raw materials, thereby reducing the working intensity of the conveyor rollers 5, and the rubber sleeve 6 on the outer wall of the conveyor roller 5 is not easy to heat up and wear, so the number of maintenance and maintenance costs can be reduced, and after the conveyor roller 5 descends, the rotating conveyor roller 5 can also shake off the dust on the outer wall, so that the conveyor roller 5 is not easy to slip, maintain a high loading efficiency and transmission accuracy, and can fully contact with the air to obtain efficient heat dissipation.

[0055] When the strip frame 3 drives the conveyor roller 5 to move downward, the strip frame 3 will also drive the driven gear 20 to sweep across the rack 19, and the rack 19 will drive the driven gear 20 to rotate, and the driven gear 20 will drive the second reciprocating screw 16 to rotate, and the second reciprocating screw 16 will drive the reciprocating push plate 18 to slide back and forth, and the reciprocating push plate 18 will drive the conveyor roller 5 to slide back and forth on the outer wall of the polygonal guide rod 8 through the circular ring 17, and the position where the conveyor roller 5 finally stops sliding does not overlap with the previous position, so that after the conveyor roller 5 is reset upward, it can prevent the conveyor roller 5 from excessively concentrating on contacting and rubbing with the steel structure raw material on a certain outer wall, so that the rubber sleeve 6 on the outer wall of the conveyor roller 5 is not easy to wear and heat up, further reducing the number of maintenance times and costs.

[0056] When the strip frame 3 moves downward, the conveying roller 5 will be close to the upper port of the suction hood 21, and will also drive the L-shaped frame 10 to move downward, and the L-shaped frame 10 will push the top pressure plate 22 to move downward, and the top pressure plate 22 will drive the suction hood 21 to move downward synchronously, so as to maintain a fixed distance between the suction hood 21 and the conveying roller 5, and the downward moving strip frame 3 will also drive the transmission wheel 30 to press on another transmission wheel 30, and the rotating shaft 7 will drive the exhaust pipe 26 to rotate through the two mutually fitting transmission wheels 30, and the exhaust pipe 26 will drive the internal fan blades 27 to rotate, and the exhaust pipe 26 will inhale air from the suction hood 21 through the suction hole 28, and the suction The air hood 21 will absorb the dust adhering to the outer wall of the rubber sleeve 6, and can also dissipate heat for the conveying roller 5 and the rubber sleeve 6, so that the rubber sleeve 6 on the outer wall of the conveying roller 5 is not easy to slip, thereby maintaining good conveying accuracy. The dust and air absorbed by the exhaust pipe 26 will be discharged from the other end thereof. When the air hood 21 moves downward, the air hood 21 will also drive the support rod 24 to slide toward the inner bottom direction of the vertical pipe 23 and compress the spring 25. After the strip frame 3 drives the L-shaped frame 10 to reset upward, the top pressure plate 22 is no longer subjected to the top pressure of the L-shaped frame 10. At this time, the spring 25 will elastically reset and drive the air hood 21 to move upward and reset through the support rod 24.

[0057] After the conveying roller 5 approaches the upper port of the air suction hood 21, the brush 29 on the outer wall of the exhaust pipe 26 will contact the outer wall of the conveying roller 5, thereby more efficiently cleaning the dust on the outer wall of the rubber sleeve 6, and the reciprocating conveying roller 5 will make the rubber sleeve 6 slide back and forth on the brush 29, so that the brush 29 can more efficiently clean the dust on the outer wall of the rubber sleeve 6, and the reciprocating conveying roller 5 can be in more sufficient contact with the flowing air, thereby enabling the conveying roller 5 and the rubber sleeve 6 to obtain better heat dissipation.
