Description

Technical Field

[0001] This utility model relates to the technical field of coated steel bar production equipment, and in particular to a rolling coated steel bar production line. Background Technology

[0002] To achieve uniform coating of rebar, the rebar needs to be driven to roll during spraying in the equipment. This typically includes a rebar feeding assembly, a spraying assembly, and a rolling drive assembly. To maximize coverage, the spray gun nozzle needs to be at a certain angle to the rebar's transport path, and the rebars must be kept at an appropriate distance. If the rebars are too close, parts of their surface will be blocked from spraying; if they are too far apart, paint will be sprayed onto the transport line, resulting in paint waste. Therefore, the rebars need to be fed into the rebar spraying equipment one by one. However, currently... Current equipment struggles to automate the equidistant feeding of rebars, requiring manual labor to manually remove each rebar from the rebar feeding assembly, arrange them at intervals, and feed them into the rebar spraying equipment. Furthermore, the spray guns in current rebar spraying equipment can only move in one direction, either the rolling direction of the rebar or its axial direction. Moreover, the spray gun can only be adjusted at its angle, not at the longitudinal distance between the spray gun and the rebar. Therefore, to accommodate rebars of different sizes, the angle of the spray gun must be adjusted, necessitating a wider range of angle adjustments, as illustrated in patent document CN110932793B.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a rolling coated steel bar production line. Compared with the prior art, this utility model has at least the following technical effects: 1. The combination structure of the steel bar feeding device and the three-axis moving component can realize the automated feeding of steel bars one by one, replacing the traditional manual feeding method, greatly improving feeding efficiency and reducing labor costs; at the same time, the three-axis moving component drives the spray gun group to move in multiple directions, breaking the limitation of the traditional spray gun moving in one direction, so that the spray gun can flexibly adjust the relative position with the steel bar to adapt to the spraying needs of steel bars of different sizes.

[0015] 2. The three-axis moving component structure combined with the staggered arrangement of the spray gun group, the cooperation of the X-axis, Y-axis and Z-axis moving parts enables the spray gun group to achieve multi-dimensional precise movement in space. The staggered arrangement of adjacent spray gun groups and the partial overlap design of the spraying area effectively avoid spraying dead corners and ensure full coverage of the coating on the surface of the steel bars.

[0016] 3. The lifting drive unit can adapt to steel bars of different diameters by driving the conveyor belt to move up and down, ensuring that the steel bars are in close contact with the conveyor belt to achieve stable rolling; the staggered and partially interlaced setting of the conveyor belt not only avoids interference with the spray gun group, but also ensures the continuity and stability of the steel bar rolling process, thus providing a guarantee for uniform spraying.

[0017] 4. The groove width adjustment component and groove depth adjustment component of the feeding groove allow the size of the feeding groove to be flexibly adjusted according to the diameter of the steel bar, breaking the limitation of traditional feeding devices that can only adapt to a single specification of steel bar, improving the adaptability of the production line to steel bars of different specifications, and expanding the application range of the equipment.

[0018] 5. The width of the inlet groove of the feeding groove is controlled by adjusting the distance between the two first positioning blocks. The spacing of the first locking holes allows for multi-level adjustment of the groove width to meet the positioning requirements of steel bars of different diameters, ensuring that only one steel bar of the appropriate size can be inserted at a time, achieving single-bar feeding. The separate second positioning block cooperates with the first positioning block. The first positioning block ensures that even after the groove width of the feeding groove is reduced, the opening end surface of the feeding groove can still fit against the circumference of the turntable, preventing gaps between the sidewalls of the adjusted second positioning block and the original sidewalls. The second positioning block ensures that the sidewalls remain parallel to each other after adjustment and are adjusted to a suitable size with the inner wall. The adjustment direction of the second positioning block is complementary to that of the first positioning block, making the groove width adjustment more flexible and adaptable to a wider range.

[0019] 6. Adjust the effective depth of the feeding groove by changing the position of the moving block so that the feeding groove can only accommodate one steel bar. Attached Figure Description

Multiple turntables 33 are installed on the rotating shaft 32. Each turntable 33 has a feeding groove 34 in the radial direction on its outer periphery. The feeding groove 34 matches the size of the steel bar 7 that needs to be fed. The steel bar feeding bin 1 is located on one side of the rotating feeding mechanism 3. The lower side wall of the steel bar feeding bin 1 near the rotating feeding mechanism 3 has a discharge port 11. The lower side frame of the discharge port 11 is clearance-fitted with the circumferential surface of the turntable 33. The height of the discharge port 11 is lower than the upper end of the turntable 33. The lower side of the entrance of the frame 21 is lower than the height of the maximum lateral dimension of the turntable 33. The combination of the rebar feeding device and the three-axis moving component 24 enables automated feeding of rebars 7 one by one, replacing the traditional manual feeding method, greatly improving feeding efficiency and reducing labor costs; at the same time, the three-axis moving component 24 drives the spray gun assembly 22 to move in multiple directions, breaking the limitation of the traditional spray gun 222 moving in only one direction, so that the spray gun 222 can flexibly adjust its relative position with the rebar 7 to adapt to the spraying needs of rebars 7 of different sizes.

[0041] Please see Figures 1 to 3Preferably, the three-axis moving assembly includes an X-axis moving component 241, a Y-axis moving component 242, and a Z-axis moving component 243. The X-axis moving component 241 is mounted above the frame 21 via a bracket 25. The moving direction of the X-axis moving component 241 is parallel to the rolling direction of the reinforcing bar 7. At least two Y-axis moving components 242 are mounted on the X-axis moving component, and the two Y-axis moving components 242 are spaced apart. The Z-axis moving component 243 is mounted on each Y-axis moving component 242. The spray gun assembly 22 is mounted on the lower end of the Z-axis moving component 243. The spray gun assemblies 22 connected to adjacent Y-axis moving components 242 are staggered, and the spraying areas of adjacent spray gun assemblies 22 in the rolling direction of the reinforcing bar 7 partially overlap in the axial direction of the reinforcing bar 7. The three-axis moving component structure and the staggered arrangement of the spray gun assembly 22, along with the cooperation of the X-axis, Y-axis, and Z-axis moving parts 243, enable the spray gun assembly 22 to achieve precise multi-dimensional movement within space. The staggered arrangement of adjacent spray gun assemblies 22 and the partial overlap of the spraying area effectively avoid spraying dead corners, ensuring full coating coverage of the steel reinforcement 7 surface. The X-axis moving parts 241, Y-axis moving parts 242, and Z-axis moving parts 243 can be existing mechanisms such as gantry cranes, which will not be described in detail.

[0042] Please see Figures 1 to 3 Preferably, the number of rolling drive assemblies 23 corresponds to the number of Y-axis moving parts 242, and they are installed at positions opposite to the corresponding Y-axis moving parts 242. Each set of rolling drive assemblies 23 includes a connecting frame 231 and a conveyor belt 232. The connecting frame 231 is fixed on the bracket 25 and is lower than the Y-axis moving parts. The lower side of the connecting frame 231 is connected to the conveyor belt 232 through a lifting drive 233. The conveyor belt 232 is staggered from the spray gun assembly 22. The lower surface of the conveyor belt 232 is connected to the upper surface of the frame 21 by a reinforcing bar 7, and the reinforcing bar 7 is in contact with the lower surface of the conveyor belt 232. The conveyor belts 232 of two adjacent sets of rolling drive assemblies 23 are staggered. The conveyor belts 232 of two adjacent sets of rolling drive assemblies 23 partially intersect in the rolling direction of the reinforcing bar 7. The lifting drive component 233 drives the conveyor belt 232 to rise and fall, accommodating steel bars 7 of different diameters and ensuring close contact between the steel bars 7 and the conveyor belt 232 for stable rolling. The staggered and partially interlaced arrangement of the conveyor belt 232 avoids interference with the spray gun assembly 22 and ensures the continuity and stability of the steel bar 7's rolling process, thus guaranteeing uniform spraying. A preferred lifting drive component 233 can be a telescopic cylinder or a linear lifting module composed of a motor and lead screw.

[0043] Please see Figures 1 to 3 Preferably, the spray gun assembly 22 includes a spray gun 222 and a universal connector 221. The universal connector 221 is fixed to the lower end of the Z-axis moving part 243, and the spray gun 222 is connected to the universal connector 221 to facilitate adjustment of the spraying angle of the spray gun 222.

The rolling drive assembly 23 corresponding to this Y-axis moving part 242 has two conveyor belts 232. One set of the three spray gun assemblies 22 moves between the two conveyor belts 232, while the other two sets move and spray in the space outside the two conveyor belts 232. The width of these spaces is wider than the conveyor belts 232 in the latter rolling drive assembly 23, providing sufficient spraying space for the spray gun assemblies 22 and avoiding excessive spraying.

The two sets of spray gun groups 22 are respectively located between the three conveyor belts 232 to form two intervals. These two intervals correspond exactly to the two conveyor belts 232 of the previous rolling drive assembly 23. The width of the interval is greater than the width of the conveyor belt 232 to provide sufficient space for the spray gun groups 22 to move along the axial direction of the reinforcing bar 7 and avoid spraying blind spots.

[0045] Please see Figure 1 , Figures 4 to 14 Preferably, the feeding groove 34 is connected to a groove width adjustment component 4 and a groove depth adjustment component 5; the groove width adjustment component 4 is located on one end face of the turntable 33 in the axial direction, and the groove depth adjustment component 5 is located on the other end face of the turntable 33 in the axial direction. The groove width adjustment component 4 and the groove depth adjustment component 5 of the feeding groove 34 allow the size of the feeding groove 34 to be flexibly adjusted according to the diameter of the reinforcing bar 7, breaking the limitation of traditional feeding devices that are only suitable for a single specification of reinforcing bar 7, improving the adaptability of the production line to reinforcing bars 7 of different specifications, and expanding the application range of the equipment.

[0046] Please see Figure 1 , Figures 4 to 14Preferably, the slot width adjustment component 4 includes two first positioning blocks 41 and a first fixing member 42. The two first positioning blocks 41 are respectively fixed on both sides of the feeding groove 34 in the circumferential direction of the turntable 33, and can approach or move away from each other in the circumferential direction of the turntable 33. The first fixing member 42 passes through the first positioning block 41 and the turntable 33. The end face of the slot width adjustment component 4 is provided, and multiple first locking holes 43 are provided at intervals on both sides of the feeding groove 34 from the direction close to the feeding groove 34 to the direction away from the feeding groove 34. The first fixing member 42 can pass into the first locking holes 43. The slot width at the entrance of the feeding groove 34 is adjusted and controlled by adjusting the distance between the two first positioning blocks 41, and the interval of the first locking holes 43 can realize multi-level adjustment of the slot width to meet the positioning requirements of steel bars 7 of different diameters, ensuring that only one steel bar 7 of the appropriate size can enter at a time, realizing single-bar loading.

[0047] Please see Figure 1 , Figures 4 to 14 Preferably, the turntable 33 has an annular guide recess 44 on the outer ring of the end face of the slot width adjustment component 4. The first positioning block 41 is arc-shaped, and the surface of the first positioning block 41 away from the axis of the turntable 33 has the same curvature as and coincides with the outer circumferential surface of the turntable 33.

The first locking hole 43 is provided on the surface of the guide recess 44, and a plurality of first locking holes 43 are spaced apart along a curve parallel to the circumferential surface of the turntable 33. The ends of the two first positioning blocks 41 facing each other are pointed, and the pointed ends are formed on the surfaces of the first positioning blocks 41 away from the axis of the turntable 33.

[0048] Please see Figure 1 , Figures 4 to 14Preferably, the groove width adjustment component 4 further includes a second positioning block 46, with two second positioning blocks 46 symmetrically arranged on both sides of the feeding groove 34. A second guide groove 47 parallel to the side wall of the feeding groove 34 is provided on the second positioning block 46, and a second fixing member 49 is provided in the second guide groove 47. The turntable 33 is provided with the end face of the groove width adjustment component 4, and a plurality of second locking holes 48 are symmetrically provided on both sides of the feeding groove 34. The second locking holes 48 are spaced apart along a direction perpendicular to the side wall of the feeding groove 34 and are arranged in two rows. The second fixing member 49 passes through the corresponding second locking hole 48. The second positioning block 46 forms a pointed tip on the side closer to the feeding groove 34 and away from the axis of the turntable 33. The dimension of the guide recess in the axial direction of the turntable 33 is equal to the thickness of the first positioning block 41. The pointed tips of the first positioning block 41 and the second positioning block 46 can form unnotched corners on both sides of the opening end of the feeding groove 34. The second positioning block 46 and the first positioning block 41 are designed to work together. The first positioning block 41 ensures that even after the width of the feeding groove 34 is reduced, the outer surface of the opening end can still fit against the circumference of the turntable 33. There will be no gap between the side wall and the original side wall of the adjusted second positioning block 46. The second positioning block 46 ensures that the side walls remain parallel to each other after adjustment and are adjusted to a suitable size with the inner wall. The adjustment direction of the second positioning block 46 is complementary to that of the first positioning block 41, making the groove width adjustment more flexible and the adaptation range wider.

[0049] Please see Figure 1 , Figures 4 to 14 Preferably, the groove depth adjustment assembly 5 includes a moving block 51 and a third fixing member 52. The moving block 51 can move in a direction approaching or away from the opening of the feeding groove 34, and the third fixing member 52 passes between the moving block 51 and the turntable 33. By changing the position of the moving block 51, the effective depth of the feeding groove 34 is adjusted so that the feeding groove 34 can only accommodate one steel bar 7.

[0050] Please see Figure 1 , Figures 4 to 14Preferably, the end face of the groove depth adjustment component 5 is symmetrically provided with multiple third locking holes 53 on both sides of the feeding groove 34. A third fixing member 52 is respectively provided on both sides of the moving block 51, and the third fixing member 52 is inserted into the corresponding third locking hole. The symmetrical third locking holes 53 on both sides cooperate with the third fixing members 52 to make the fixing of the moving block 51 more reliable. It is not easy to be displaced under the centrifugal force generated by the high-speed rotation of the turntable 33, ensuring the stability of the groove depth dimension and ensuring that only one steel bar 7 can be accommodated at any time. The third locking hole 53 can be a stepped hole with internal thread, and the bolt head is embedded in the hole to avoid protruding from the surface of the turntable 33. Spring washers and anti-loosening nuts can be provided on both sides of the moving block 51 to enhance the anti-loosening effect of the bolt and adapt to the long-term vibration working environment.

[0051] Please see Figure 1 , Figures 4 to 14 Preferably, the rotating shaft 32 is provided with multiple turntables 33 at intervals, and the feeding grooves 34 on two adjacent turntables 33 are aligned with each other; one feeding groove 34 is provided on the circumference of each turntable 33, or two or more feeding grooves 34 are arranged in a circular array on the circumference of each turntable 33; the number of turntables 33 can be adjusted according to the maximum length of the reinforcing bar 7, for example, one turntable 33 can be set for a 1-meter long reinforcing bar 7. According to the feeding speed requirements, a corresponding number of feeding grooves 34 can be set.

[0052] Please see Figure 1 , Figure 2 , Figure 7 Preferably, an arc-shaped guide plate 6 is provided between the inlet and the outlet 11, and on the upper side of the turntable 33. The curvature of the inner side of the arc-shaped guide plate matches the curvature of the outer circumference of the turntable 33. The arc-shaped guide plate 6 provides a stable conveying channel for the reinforcing bar 7, preventing the reinforcing bar 7 from detaching from the turntable 33 under centrifugal force, and ensuring that the reinforcing bar 7 slides smoothly into the inlet of the rolling spraying equipment 2.

[0053] Please see Figure 15 , Figure 16Preferably, a lifting baffle 12 is installed on the side wall of the rebar supply hopper 1 near the rotary feeding mechanism 3. The lifting baffle 12 can be lowered to block the discharge port 11. The bottom plate of the rebar supply hopper 1 is inclined, and its height gradually decreases from the side away from the rotary feeding mechanism 3 to the side closer to the rotary feeding mechanism 3. The effective height of the discharge port 11 can be flexibly adjusted according to the diameter of the rebar 7. For example, for a rebar 7 with a diameter of mm, the baffle is lowered to the effective height of the discharge port 11 to mm, ensuring that only one rebar 7 can pass through. When the spraying equipment 2 is not in operation, the baffle can be lowered completely to close the discharge port 11, preventing the continuous output of rebar 7 and causing accumulation. The discharge port 11 is directly connected to the outer circumference of the turntable 33. In this way, if the groove of the turntable 33 is not aligned with the discharge port 11, the rebar 7 cannot come out of the discharge port 11 due to the obstruction of the turntable 33. The inclined bottom plate of the steel bar supply silo and the optimized position of the discharge port 11 enable the steel bars 7 to be continuously and smoothly conveyed to the turntable 33, avoiding jamming or accumulation.

[0054] Please see Figure 15 , Figure 16 Preferably, the side wall of the lifting baffle 12 of the steel bar supply hopper 1 is provided with a plurality of positioning holes 13 spaced longitudinally. The lifting baffle 12 has a connecting hole, and the connecting hole is provided with a positioning pin 14, which can be inserted into the positioning hole 13. The height scale of the discharge port 11 corresponding to the positioning hole 13 can be marked on the baffle, which facilitates quick positioning by the operator without the need for repeated measurement.

[0055] Please see Figure 1 , Figure 2 Preferably, a paint recovery bin 26 is provided on the lower side of the frame 21 for recovering spraying dust; the discharge port 11 of the rolling spraying equipment 2 is provided with a ramp, which is connected to a storage bin 27 for storing the sprayed steel bars 7.

[0056] The working principle of this utility model is as follows:

[0057] First, based on the diameter of the steel bar 7 to be processed, the dimensions of the feeding groove 34 of the turntable 33 are adjusted using the groove width adjustment component 4 and the groove depth adjustment component 5: the first positioning block 41 and the second positioning block 46 are moved and fixed in the corresponding locking hole positions by the first fixing component 42 and the second fixing component 49 to achieve groove width adjustment; the moving block 51 is moved and fixed by the third fixing component 52 to complete groove depth adjustment. After ensuring that the adjustment is completed, the equipment is started, and the steel bar 7 in the steel bar supply bin 1 falls into the feeding groove 34 of the turntable 33 of the rotating feeding mechanism 3 through the discharge port 11 under the action of gravity. Since the lower side frame of the discharge port 11 is fitted with the circumference of the turntable 33 with a clearance, multiple steel bars 7 can be prevented from falling into the same groove at the same time. The height of the conveyor belt 232 is adjusted by the lifting drive component 233, and the angle of the spray gun 222 is adjusted by the universal connector 221 and the height of the spray gun 222 is adjusted by the Z-axis moving component 243, so that the spraying angle of the spray gun 222 achieves the optimal coverage range (for example, the distance between the spray gun 222 and the surface of the steel bar 7 is 200~300mm, and the spraying angle (the angle between the jet axis of the thermal spray gun 222 and the horizontal plane of the steel bar 7 production line) is 60°~90°. Given that the distance between the surfaces of the steel bars 7 is 2mm, the spraying angle can preferably be 60°~75° to avoid thermal spraying loss caused by the gap between the steel bars 7).

[0058] Subsequently, the drive mechanism drives the rotating shaft 32 to rotate, which in turn drives the turntable 33 to rotate. When the feeding groove 34 containing the reinforcing bar 7 rotates to the entrance of the frame 21, since the height of the lower side of the entrance of the frame 21 is lower than the height of the maximum lateral dimension of the turntable 33, the reinforcing bar 7 falls smoothly into the area of ​​the rolling drive assembly 23 on the frame 21 under the action of gravity. At this time, the lower surface of the conveyor belt 232 on the entrance side of the spraying equipment 2 is inclined upward, which facilitates the reinforcing bar 7 to roll into the space between the conveyor belt 232 and the frame 21, so that the reinforcing bar 7 contacts the lower surface of the conveyor belt 232, and the conveyor belt 232 starts to drive the reinforcing bar 7 to roll along its own axis.

[0059] Simultaneously, the three-axis moving assembly 24 begins to operate according to the dimensions of the reinforcing bar 7 and the spraying requirements: the Y-axis moving component 242 drives the Z-axis moving component 243 to move along the axial direction of the reinforcing bar 7, thereby driving the spray gun assembly 22 to move along the axial direction to spray a specified distance (avoiding collision with the conveyor belt 232). Then, all conveyor belts 232 rotate synchronously, driving the reinforcing bar 7 to roll forward a certain distance (e.g., half a circle or 1 / 4 circle, etc.); after that, it moves along the X-axis to adjust to the spraying position of the next reinforcing bar 7. Then, the Y-axis moving component 242 drives the Z-axis moving component 243 to move in the opposite direction, thereby driving the spray gun assembly 22 to move in the opposite direction to spray; the spraying trajectory can be a square shape (e.g., ...). Figure 17 (as shown) or a rectangular wavy shape (such as...) Figure 18As shown), adjustments are made as needed until the entire circumference of the area corresponding to the reinforcing bar 7 is sprayed within the working range of the preceding Y-axis moving component 242. Driven by the corresponding conveyor belt 232 of the preceding Y-axis moving component 242, it moves to the connection position of the corresponding conveyor belt 232 of the following Y-axis moving component 242. The following conveyor belt 232 carries and rolls the remaining unsprayed area for spraying. The spraying component on the following Y-axis moving component 242 also moves and sprays according to the aforementioned trajectory until the complete spraying of the remaining circumference is completed. After spraying is completed, the reinforcing bar 7 rolls at least two revolutions or more, and then rolls out of the spraying equipment 2 under the pressure of the conveyor belt 232.
