Description

Technical Field

[0001] This utility model relates to the field of coated steel bar production equipment, and in particular to a device that can feed steel bars of various diameters one by one. Background Technology

[0002] To achieve uniform coating of steel bars, the steel bars need to be driven to roll during spraying. Furthermore, to maximize coverage, the nozzle of the spray gun needs to be at a certain angle to the steel bar's conveying path, and the steel bars must maintain an appropriate distance from each other. If the distance is too close, parts of the steel bar surface will be blocked and cannot be sprayed; if the distance is too far, the coating will be sprayed onto the conveyor line, resulting in waste. Therefore, existing steel bar production lines typically employ a stepped feeding system for steel pipe raw materials, located between the steel bar supply silo and the spraying equipment, as shown in patent document CN219688566U. This system achieves step-by-step transfer of steel bars, maintains a consistent feeding speed, and ensures that the steel bars are fed at appropriate intervals within the spraying equipment. However, it can only accommodate one-by-one feeding of steel bars of a single diameter. This is because the size of its steps cannot be changed. If the diameter of the steel bar is too small, the steps may accommodate two steel bars at the same time. If the steel bar is too large, the steps cannot hold the steel bar, and it is impossible to lift the steel bar step by step. This means that when the steel bar production line switches to produce different types of steel bars, it is necessary to change the step feeding system to match the diameter of the steel bars. The equipment purchase cost is high and the replacement time is long. Utility Model Content

The turntable is positioned on the end face of the groove width adjustment component, and multiple second locking holes are symmetrically arranged on both sides of the feeding groove. The second locking holes are spaced apart along a direction perpendicular to the sidewall of the feeding groove, and are arranged in two rows. The second fixing member passes through the corresponding second locking hole. The second positioning block forms a pointed tip on the side closest to the feeding groove and on the side furthest from the turntable axis. The dimension of the guide recess in the axial direction of the turntable is equal to the thickness of the first positioning block. The pointed tips of the first and second positioning blocks can form an angle without notches on both sides of the opening end of the feeding groove.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a device for feeding steel bars of various diameters one by one. Compared with the prior art, this utility model has at least the following technical effects: 1. The combination of the groove width adjustment component and the groove depth adjustment component enables flexible adjustment of the groove width and groove depth of the feeding groove, allowing the device to adapt to steel bars of different diameters. This effectively solves the problem that the existing stepped feeding system can only adapt to steel bars of a single diameter, ensuring that only one steel bar can enter the feeding groove at a time. This avoids the need to replace equipment when switching production lines, reducing equipment costs and saving replacement time. 2. The groove width at the entrance of the feeding groove is controlled by adjusting the distance between the two first positioning blocks, and the spacing of the first locking holes allows for multi-level adjustment of the groove width, meeting the positioning requirements of steel bars of different diameters. This ensures that only one steel bar of the appropriate size can enter at a time, achieving single-bar feeding. 3. The separate second positioning block works in conjunction with the first positioning block. The first positioning block ensures that even after the width of the feeding groove is reduced, the opening end surface of the feeding groove can still fit snugly 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, achieving 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. 4. The effective depth of the feeding groove is adjusted by changing the position of the moving block, ensuring that the feeding groove can only accommodate one rebar at a time. 5. The lifting baffle can adjust the size of the discharge port according to the diameter of the produced rebar, ensuring that only one rebar can pass through at a time. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Please see Figures 1 to 13 A device for feeding steel bars of various diameters one by one is provided between a steel bar supply bin 1 and a spraying device 2. It includes a drive mechanism and a rotary feeding mechanism 3. The rotary feeding mechanism 3 includes a mounting frame 31, on which a rotating shaft 32 is mounted. The rotating shaft 32 is connected to the drive mechanism. A turntable 33 is mounted on the rotating shaft 32. A feeding groove 34 is formed radially on the outer circumference of the turntable 33. The feeding groove 34 is connected to a groove width adjustment component 4 and a groove depth adjustment component 5. The steel bar supply bin 1 is located on one side of the rotary feeding mechanism 3. A discharge port 11 is formed on the lower side wall of the side of the steel bar supply bin 1 closest to the rotary feeding mechanism 3. The lower edge 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 inlet of the spraying device is lower than the height of the maximum lateral dimension of the turntable 33. By combining the groove width adjustment component 4 and the groove depth adjustment component 5, the feeding groove 34 can accommodate various steel bars 7 with diameters ranging from 10 to 80 mm. After adjustment, the clearance between the groove size and the diameter of the steel bar 7 is controlled at 0.5-1 mm, ensuring that only one steel bar 7 can be accommodated at a time. Preferably, the drive mechanism (not shown) can be composed of a geared motor, chain, and chain, etc., which are existing technologies and will not be described in detail.

[0031] Please see Figures 5 to 11 Preferably, 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. This avoids interference between the groove width adjustment component 4 and the groove depth adjustment component 5.

[0032] Please see Figure 5 , Figure 6 , Figures 9 to 11Preferably, 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 disposed 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 one of the first locking holes 43. By adjusting the distance between the two first positioning blocks 41, the slot width at the entrance of the feeding groove 34 is controlled so that only one steel bar 7 of various sizes can enter at a time. 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.

[0033] Please see Figure 5 , Figure 6 , Figures 9 to 11 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 positioning block 41 has an arc-shaped first guide groove 45, which is parallel to the outer circumferential surface of the turntable 33. The first fixing member 42 passes through the first guide groove 45. 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. The cooperation between the arc-shaped guide groove and the annular guide recess 44 provides a precise movement trajectory for the first positioning block 41, avoiding deviation during adjustment and ensuring the accuracy of groove width adjustment. The flush setting of the first positioning block 41 with the circumference of the turntable 33 completely eliminates any surface protrusions or gaps that may occur after adjustment, preventing the reinforcing bar 7 from being scratched or stuck in the gap during the feeding process, while ensuring the regularity of the groove opening end and ensuring that a single reinforcing bar 7 can enter smoothly.

[0034] Please see Figure 5 , Figure 6 , Figures 9 to 11Preferably, 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 is provided in the second guide groove 47. The turntable 33 is positioned on 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 tip of the first positioning block 41 and the pointed tip of the second positioning block 46 can form an angle without notches on both sides of the opening end of the feeding groove 34. The first positioning block 41 is arc-shaped, and its surface away from the axis of the turntable 33 coincides with the circumference of the turntable 33. After the groove width is reduced and adjusted, it can ensure that the open end surface of the feeding groove 34 is still in close contact with the circumference of the turntable 33, and will not form a gap between the second positioning block 46 and the original side wall of the feeding groove 34, thus avoiding the reinforcing bar 7 getting stuck in the gap and causing feeding failure. The second positioning block 46 can ensure that the side walls of the feeding groove 34 are always parallel to each other after adjustment, and accurately adjust the inner wall of the groove to the size of the reinforcing bar 7. Moreover, its adjustment direction perpendicular to the side wall of the feeding groove 34 complements the adjustment direction of the first positioning block 41 along the circumference of the turntable 33, making the groove width adjustment more flexible and the range of the diameter of the reinforcing bar 7 that can be adapted is wider. At the same time, it ensures the regularity of the inner wall of the groove and ensures that a single reinforcing bar 7 can be stably accommodated.

[0035] Please see Figures 5 to 8 Preferably, the groove depth adjustment component 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 can be precisely adjusted. The adjusted groove depth is strictly controlled to accommodate only the height of one steel bar 7, which restricts the stacking of multiple steel bars 7 into the groove from a vertical perspective. This, together with the groove width adjustment, forms a double guarantee, further enhancing the effect of "single-bar feeding" and avoiding the problem of multiple steel bars 7 stacking vertically due to excessive groove depth. The first fixing member 42, the second fixing member 49, and the third fixing member 52 are bolts.

[0036] Please see Figures 5 to 8Preferably, 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.

[0037] Please see Figures 1 to 5 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 the turntable 33, or two or more feeding grooves 34 are arranged in a ring array on the circumference of the turntable 33; an arc-shaped guide plate 6 is provided between the inlet and the outlet 11 and on the upper side of the turntable 33, and the curvature of the inner side of the arc-shaped 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, prevents the reinforcing bar 7 from detaching from the turntable 33 under the action of centrifugal force, and ensures that the reinforcing bar 7 slides smoothly into the inlet of the spraying equipment; the number of turntables 33 can be adjusted according to the maximum length of the reinforcing bar 7, such as 6 turntables 33 for a 9-meter long reinforcing bar 7.

[0038] Please see Figure 12 , Figure 13 Preferably, a lifting baffle 12 is installed on the side wall of the rebar supply hopper 1 near the rotating feeding mechanism 3. The lifting baffle 12 can be lowered to block the discharge port 11. 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 25mm, the baffle is lowered to an effective height of 30mm at the discharge port 11 to ensure that only one rebar 7 can pass through. When the spraying equipment is not in operation, the baffle can be lowered completely to close the discharge port 11, preventing the continuous output of rebar 7 from 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 bottom plate of the steel bar feeding hopper 1 is set at an angle, and its height gradually decreases from the side away from the rotating feeding mechanism 3 to the side closer to the rotating feeding mechanism 3. The angled bottom plate of the feeding hopper and the optimized position of the discharge port 11 enable the steel bars 7 to be continuously and smoothly fed to the turntable 33, avoiding jamming or accumulation.

[0039] Please see Figure 12 , Figure 13 Preferably, the side wall of the lifting baffle 12 in the steel bar 7 feeding hopper is provided with a plurality of positioning holes 13 spaced longitudinally. The lifting baffle 12 has a connecting hole with a positioning pin that can be inserted into the positioning hole 13. The height of the discharge port 11 corresponding to the positioning hole 13 can be marked on the baffle for quick positioning by the operator without repeated measurement.

[0040] The working principle of this utility model is as follows:

[0041] First, adjust the groove width. Based on the diameter of the steel bar 7 to be processed (e.g., 28mm), loosen the first fixing member 42 and the third fixing member 52 of the groove width adjustment assembly 4, and push the first positioning block 41 to move along the arc-shaped guide groove, so that the distance between the two first positioning blocks 41 is initially adjusted to 29mm. At this time, the outer surface of the first positioning block 41 is always in contact with the circumference of the turntable 33. Then, push the second positioning block 46 to move along the second guide groove 47 towards the inside of the groove, and precisely fine-tune the distance between the inner walls of the groove to 28.5mm, ensuring that the side walls are parallel and avoiding the first positioning block 46. A notch appears at the tip between the first and second positioning blocks 46; then the groove depth is adjusted by loosening the third fixing part 52 of the groove depth adjustment component 5 and pushing the moving block 51 towards the groove opening, so that the effective depth of the feeding groove 34 is adjusted to 30mm, which can only accommodate one steel bar 7 with a diameter of 28mm. Then the third fixing part 52 is tightened to fix it; finally, the height of the lifting baffle 12 is adjusted, and the effective height of the discharge port 11 is adjusted to 35mm according to the diameter of the steel bar 7. The positioning pin is inserted into the corresponding positioning hole 13 to fix it, ensuring that only a single steel bar 7 is allowed to pass through.

[0042] After the continuous feeding stage is started, the steel bars 7 to be sprayed are placed in batches into the steel bar supply bin 1. Under the gravity guidance of the inclined bottom plate, the steel bars 7 slowly slide towards the discharge port 11. Since the discharge port 11 has been adjusted to a size that only allows a single steel bar 7 to pass through, the steel bars 7 are discharged one by one from the discharge port 11. At this time, the inlet of the feeding groove 34 is exactly aligned with the discharge port 11, and the steel bars 7 can fall into the feeding groove 34 of the turntable 33. At this time, the groove width (28.5mm) and groove depth (30mm) are precisely adapted to the diameter of the steel bar 7, ensuring that a single steel bar 7 is stably accommodated without shaking or multiple bars being squeezed in. Then the drive motor starts and drives the rotating shaft 32 to rotate through the coupling. The rotating shaft 32 drives three synchronously rotating turntables 33, and the steel bars 7 embedded in the grooves move in a circular motion with the turntables 33. When the steel bars 7 rotate with the turntables 33 to the upper area, the arc-shaped guide plate 6 limits the movement of the steel bars 7.

[0043] When the turntable 33 rotates to the position of the reinforcing bar 7 and aligns with the inlet of the spraying equipment, since the lower side of the inlet is slightly lower than the highest point of the turntable 33, the reinforcing bar 7, under the combined action of gravity and the rotational inertia of the turntable 33, smoothly detaches from the groove and slides into the inlet of the spraying equipment along the arc-shaped guide plate 6, completing the feeding process of a single reinforcing bar 7.

[0044] Throughout the entire process, the discharge port controls "single entry", the groove size controls "single accommodation", and the guide structure ensures "single conveying". This completely solves the problem that existing equipment cannot adapt to multiple diameter steel bars and is prone to multiple feedings. At the same time, flexible adjustment avoids equipment replacement, reduces costs and improves efficiency.
