Description

Technical Field

[0001] This utility model relates to the technical field of epoxy-coated steel bar production equipment, and in particular to a buffer feeding device for epoxy-coated steel bar production lines. Background Technology

[0002] Traditional epoxy-coated rebar production lines feed rebars sequentially into a medium-frequency heating system and then into a spraying system after shot blasting. In existing equipment, the medium-frequency heating system has a limited capacity for single-batch feeding (significantly smaller than the shot blasting system). Since the shot blasting system delivers the entire batch together, the existing roller conveyor cannot separate and temporarily store any product; all products are pushed towards the medium-frequency heating system, causing a buildup at the inlet and blocking the inlet. Therefore, the shot blasting system can only process the same number of rebars as the medium-frequency heating system in a single batch. However, the shot blasting process takes more than twice the time of rebar heating and coating. This results in the electrostatic spraying system having to wait for the arrival of new rebars after shot blasting after coating a batch, leading to a prolonged waiting time for the electrostatic spraying system. This makes the shot blasting system a bottleneck, severely impacting production efficiency, as illustrated in patent document CN201543577U. Utility Model Content

[0003] To address the aforementioned problems, the purpose of this invention is to provide a buffer feeding device for epoxy-coated steel bar production lines.

[0004] This utility model is implemented using the following method: A buffer feeding device for an epoxy-coated steel bar production line includes a roller conveyor located between a heating device and a shot blasting device. The roller conveyor has a frame, and multiple rollers are spaced apart in the middle of the frame. The two ends of the frame are respectively connected to the shot blasting device and the medium-frequency heating device. Each roller has multiple grooves spaced apart along the axial direction. A blocking member is provided between the roller on the side of the frame closest to the heating device and the heating device. The blocking member is located on the moving path of the product and has clearance holes corresponding to the number and position of the feed ports of the heating device. The clearance holes allow the product to pass through. A push-displacement assembly is installed in the frame at a position away from the rollers. The push-displacement assembly includes a push-drive member and a push member. The push-drive member is used to drive the push member to push the product on the roller to move a specified distance along the axial direction of the roller, so that the product that is not aligned with the clearance hole moves to the position aligned with the clearance hole.

[0005] Preferably, the pushing member includes a lifting plate, which is mounted on the pushing drive member. The lifting plate is provided with a plurality of pushing blocks, each of which is opposite to the movement trajectory of the product that is not aligned with the clearance hole. Each pushing block is provided with an inclined surface, and the inclined surface of each pushing block faces the same direction, each facing the movement trajectory of the product aligned with the clearance hole on the same side of its adjacent side.

[0006] Preferably, the pushing drive component is a first telescopic rod, and the lifting plate is installed at the extended end of the first telescopic rod; the pushing displacement assembly is provided in two sets, which are spaced apart along the moving direction of the product, and the distance between the two sets of pushing displacement assemblies is less than the length of the product.

[0007] Preferably, the lifting plate has a limiting block at one end perpendicular to the product's travel direction and facing the inclined surface of the push block, and the limiting block avoids the product's travel trajectory.

[0008] Preferably, the plurality of push blocks are equidistantly spaced on the upper surface of the lifting plate, the distance between two adjacent push blocks is equal to the width of the groove, and the gap between two adjacent push blocks is directly opposite a groove.

[0009] Preferably, the center-to-center distance between two adjacent push blocks is twice the spacing between two adjacent grooves on a single roller.

[0010] Preferably, the number of grooves on a single roller is twice or more the number of clearance holes, and the number of push blocks is the number of grooves minus the number of clearance holes.

[0011] Preferably, each of the relief holes is opposite to one of the grooves, and a number of grooves corresponding to a multiple are provided between the two grooves opposite to the two adjacent relief holes.

[0012] Preferably, an alignment assembly is further provided between the blocking member and the heating device. The alignment assembly includes an alignment plate and an alignment drive member. The alignment plate is connected to the alignment drive member. The alignment plate is driven by the alignment drive member to block the movement path of the product or to make way for the movement path of the product.

[0013] Preferably, the alignment drive includes a rotating shaft and a second telescopic rod. The rotating shaft is rotatably mounted on the frame near the heating device. The alignment plate is fixed to the outer circumferential surface of the rotating shaft. When the alignment plate is blocked, a connecting rod is provided on the side facing the heating device. The connecting rod is movably connected to the second telescopic rod to drive the rotating shaft to rotate and thus move the alignment plate to the blocking position and the avoidance position.

[0014] The beneficial effects of this utility model are as follows: This utility model provides a buffer feeding device for epoxy-coated steel bar production lines. Compared with the prior art, this utility model has at least the following technical effects: 1. By setting a blocking component and a push displacement component on the side of the frame near the heating equipment, the shot-blasted products can be temporarily stored and distributed, allowing the shot-blasting equipment to process more products at once. The products are temporarily stored in the buffer feeding device and gradually distributed into the medium-frequency heating equipment. The blocking component is provided with a clearance hole, which blocks products that are not aligned with the clearance hole. Only products aligned with the clearance hole can pass through the clearance hole and be fed into the heating equipment. The blocked products stay on the roller for temporary storage. Then, the push displacement component drives the push component, which pushes the products on the roller, so that the products that are not aligned with the clearance hole are aligned with the clearance hole. The blocked products can then be fed into the heating equipment, avoiding the accumulation and blockage of products at the inlet of the heating equipment. This effectively solves the problem of the mismatch between the shot-blasting equipment capacity and the feeding capacity of the medium-frequency heating equipment in the existing equipment, which limits the number of shot-blasted products, and improves the production efficiency of the entire epoxy-coated steel bar production line. 2. The push block features an inclined surface, which guides the product during the push process, allowing it to slide smoothly along the roller axis into the adjacent groove. This aligns products that are not properly aligned with the clearance holes, enabling them to be conveyed through the clearance holes and enter the heating equipment. This eliminates the need for the heating equipment to wait for new shot-blasted products; instead, it directly receives products temporarily stored on the rollers of the frame between the heating and shot-blasting equipment, significantly reducing waiting time and improving production efficiency. 3. The center-to-center distance between two adjacent push blocks is twice the distance between two adjacent grooves on a single roller. This dimensional design further optimizes the relative position and interaction between the push block, the grooves, and the product. During the push process, the distance and position of product movement can be more precisely controlled, ensuring that each push accurately moves the product from one groove to an adjacent one. This provides more reliable assurance for both alignment with the clearance holes and orderly temporary storage within the buffer feeding device, improving the accuracy of the equipment operation and production efficiency. 5. Each clearance hole corresponds to a groove, and between the two grooves of two adjacent clearance holes, there is a corresponding number of grooves in multiples. This positional correspondence and quantity relationship makes the arrangement and conveying of products in the buffer feeding device more regular and orderly. During product storage and sorting, it can clearly distinguish products that are about to enter the heating equipment from those that still need to be stored and wait. If the number of grooves is three times that of the clearance holes, the push drive needs to push twice, so that the products are fed into the heating equipment in three batches. 6. The added alignment components include an alignment plate and an alignment drive, which can perform further alignment operations on the products before they are conveyed from the blocking part to the heating equipment, so that the same batch of products can enter the heating holes of the heating equipment synchronously, ensuring the stability of the heating coil current of the heating equipment.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Please see Figures 1 to 6A buffer feeding device for an epoxy-coated steel bar production line includes a roller conveyor 3 located between a heating device 1 and a shot blasting device 2. The roller conveyor 3 has a frame 31, with multiple rollers 32 spaced apart in the middle of the frame 31. The two ends of the frame 31 are respectively connected to the shot blasting device 2 and the medium-frequency heating device 1. Each roller 32 has multiple grooves 321 spaced apart along the axial direction. A blocking member 33 is provided between the roller 32 on the side of the frame 31 closest to the heating device 1 and the heating device 1. The blocking member 33 is located on the moving path of the product. The stop 33 is provided with clearance holes 331 corresponding to the number and position of the feed ports of the heating device 1, and the clearance holes 331 allow the product to pass through; a push displacement assembly 4 is installed in the frame 31 at a position away from the roller 32. The push displacement assembly 4 includes a push drive 41 and a push member 42. The push drive 41 is used to drive the push member 42 to push the product on the roller 32 to move a specified distance along the axial direction of the roller 32, so that the product that is not aligned with the clearance hole 331 is moved to the position aligned with the clearance hole 331. By installing a blocking element 33 and a push-displacement component 4 on the side of the frame 31 near the heating device 1, the shot-blasted products can be temporarily stored and distributed, allowing the shot-blasting equipment 2 to process more products at once. The products are temporarily stored in the buffer feeding device and gradually distributed into the medium-frequency heating device 1. The blocking element 33 is provided with a clearance hole 331, which prevents products that are not aligned with the clearance hole 331 from being blocked. Only products that are aligned with the clearance hole 331 can pass through the clearance hole 331 and be fed into the heating device 1. The blocked products remain on the roller. The product is temporarily stored on roller 32. Then, the pusher 42 is driven by the pusher drive 41 of the pusher displacement assembly 4. The pusher 42 pushes the product on roller 32, causing the product that is not aligned with the clearance hole 331 to align with the clearance hole 331. This allows the blocked product to be fed into the heating equipment 1, preventing product accumulation and blockage at the inlet of the heating equipment 1. This effectively solves the problem of the mismatch between the capacity of the shot blasting equipment 2 and the feeding capacity of the medium-frequency heating equipment 1, which limits the number of shots blasted by the shot blasting equipment 2, and improves the overall production efficiency of the epoxy coated steel bar production line. Both the heating equipment 1 and the shot blasting equipment 2 are existing equipment and do not require specific protection.

[0024] Please see Figures 1 to 3Preferably, the pushing member 42 includes a lifting plate 421, which is mounted on the pushing drive member 41. The lifting plate 421 is provided with a plurality of pushing blocks 422. Each pushing block 422 is opposite to the movement trajectory of the product that is not aligned with the clearance hole 331. Each pushing block 422 is provided with an inclined surface. The inclined surface of each pushing block 422 faces the same direction and is facing the movement trajectory of the product aligned with the clearance hole 331 on the same side of its adjacent side. The push block 422 is provided with an inclined surface, which can guide the product to move more smoothly along the axial direction of the roller 32 and slide into the adjacent groove 321 when pushing the product. This allows the product that is not aligned with the clearance hole 331 to be aligned with the clearance hole 331 and can be conveyed by the roller through the clearance hole 331 into the heating equipment 1. This means that the heating equipment 1 does not need to wait for the shot blasting equipment 2 to produce new shot, but can directly take the product temporarily stored on the roller 32 of the frame 31 between the heating equipment 1 and the shot blasting equipment 2, which greatly reduces the waiting time and improves the production efficiency.

[0025] Please see Figures 1 to 3 Preferably, the pushing drive component 41 is a first telescopic rod, and the lifting plate 421 is installed at the extended end of the first telescopic rod; the pushing displacement assembly 4 is provided in two sets, spaced apart along the moving direction of the product, and the distance between the two sets of the pushing displacement assembly 4 is less than the length of the product. The first telescopic rod can be an electric telescopic rod, or a cylinder, hydraulic system, etc., and is not limited thereto. The two sets of pushing displacement assemblies 4, with a distance less than the length of the product, allow for a more uniform pushing action on the product on the roller 32, avoiding problems such as uneven pushing force or unreasonable pushing position leading to poor product movement or deviation.

[0026] Please see Figures 1 to 3 Preferably, multiple push blocks 422 are equidistantly spaced on the upper surface of the lifting plate 421. The distance between two adjacent push blocks 422 is equal to the width of the groove 321, and the gap between two adjacent push blocks 422 is directly opposite a groove 321. The center distance between two adjacent push blocks 422 is twice the distance between two adjacent grooves 321 on a single roller 32. This dimensional design further optimizes the relative position and interaction between the push blocks 422, the grooves 321, and the product. During the pushing process, the distance and position of the product movement can be controlled more precisely, ensuring that each push accurately moves the product from one groove 321 to an adjacent groove 321. Whether aligning with the clearance hole 331 or orderly temporary storage in the buffer feeding device, it provides more reliable assurance, improving the accuracy of device operation and production efficiency.

[0027] Please see Figures 1 to 3Preferably, the lifting plate 421 has a limiting block 423 at one end perpendicular to the product's travel direction and facing the inclined surface of the push block 422. The limiting block 423 avoids the product's travel trajectory and is used to prevent the outermost product from sliding off the roller.

[0028] Please see Figures 1 to 3 Preferably, the center distance between two adjacent push blocks 422 is twice the distance between two adjacent grooves 321 on a single roller 32. The number of grooves 321 on a single roller 32 is twice or more the number of clearance holes 331, and the number of push blocks 422 is the number of grooves 321 minus the number of clearance holes 331. This configuration provides sufficient space and flexibility for the temporary storage and distribution of products in the buffer feeding device. More grooves 321 can temporarily store more products, meeting the capacity requirements of the shot blasting equipment 2 to process more products at once. At the same time, with the cooperation of a reasonable number of push blocks 422, the temporarily stored products can be efficiently distributed one by one. Through multiple movements until they are moved into the grooves 321 opposite to the clearance holes 331, they are orderly entered into the heating equipment 1, fully tapping the potential of the buffer feeding device and further improving the overall capacity of the production line and the collaborative efficiency between various devices. Simultaneously, each time the product on the roller 32 is pushed, the product moves a distance equal to the distance between adjacent grooves 321. This ensures that regardless of the number of grooves 321 or the interval between the grooves 321 and the relief hole 331, the pushing drive 41 pushes multiple times until the product is finally pushed onto the groove 321 opposite to the relief hole 331. Preferably, in this embodiment, the number of grooves 321 is twice the number of relief holes 331.

[0029] Please see Figures 1 to 6 Preferably, each of the clearance holes 331 is directly opposite a groove 321, and a number of grooves 321 corresponding to a multiple are provided between two adjacent grooves 321 directly opposite each other. This makes the arrangement and conveying of products in the buffer feeding device more orderly and regular. During the temporary storage and sorting of products, it is possible to clearly distinguish between products that are about to enter the heating equipment 1 and products that still need to be temporarily stored. If the number of grooves 321 is three times that of clearance holes 331, then the push drive 41 needs to push twice, so that the products are fed into the heating equipment 1 in three batches.

[0030] Please see Figure 1 , Figure 5 , Figure 6Preferably, an alignment component 5 is further provided between the blocking member 33 and the heating device 1. The alignment component 5 includes an alignment plate 51 and an alignment drive member 52. The alignment plate 51 is connected to the alignment drive member 52. The alignment plate 51 is driven by the alignment drive member 52 to block the movement path of the product or to make way for the product's movement path. The added alignment component 5, including the alignment plate 51 and the alignment drive member 52, can perform further alignment operations on the product before it is conveyed from the blocking member 33 to the heating device 1, so that the same batch of products can enter the heating hole of the heating device 1 synchronously, ensuring the stability of the heating coil current of the heating device 1. All coils are powered by the same power supply. The early or late entry of the reinforcing bar will cause fluctuations in the coil current, thus affecting the heating accuracy. The setting of the alignment component can make the reinforcing bar enter synchronously and avoid current fluctuations.

[0031] Please see Figure 1 , Figure 5 , Figure 6 Preferably, the alignment drive component 52 includes a rotating shaft 521 and a second telescopic rod 522. The rotating shaft 521 is rotatably mounted on the frame 31 near the heating device 1. The alignment plate 51 is fixed to the outer circumferential surface of the rotating shaft 521. When the alignment plate 51 is blocked, a connecting rod 523 is provided on the side facing the heating device 1. The connecting rod 523 is movably connected to the second telescopic rod 522 to drive the rotating shaft 521 to rotate, thereby moving the alignment plate 51 to the blocking position and the avoidance position. Preferably, the second telescopic rod 522 is a cylinder, an electric telescopic cylinder, a hydraulic cylinder, etc., but is not limited thereto. The rotating shaft 521 can also be directly driven by a motor. In this embodiment, 10 clearance holes 331 and 20 grooves 321 are used, that is, the shot blasting equipment 2 processes 20 steel bars at a time, and the heating equipment 1 heats 1 steel bar at a time; of course, it can also be 20 clearance holes 331 and 40 grooves 321; it can also be 11 clearance holes 331 and 22 grooves 321; it can also be 21 clearance holes 331 and 42 grooves 321, and it is not limited to these.

[0032] The working principle of this utility model is as follows:

[0033] The shot blasting equipment 2 conveys the shot-blasted epoxy-coated steel bars to the frame 31 of the buffer feeding device. The steel bars move forward with the rotation of the roller 32. When the steel bars move to the side close to the heating equipment 1, the blocking member 33 prevents the steel bars from moving forward. At this time, some steel bars will be aligned with the clearance hole 331 on the blocking member 33, while some that are not aligned will be blocked. The steel bars aligned with the clearance hole 331 will be conveyed by the roller 32 through the clearance hole 331 and abut against the alignment member. After all the steel bars that have passed through the clearance hole 331 abut against the alignment member, the second telescopic rod 522 retracts, causing the alignment member to rotate downward around the center of the rotating shaft 521 to make clearance. The steel bars that have passed through the clearance hole 331 will continue to be conveyed forward by the roller 32 and enter the heating equipment 1 for heating.

[0034] After the reinforcing bar passing through the clearance hole 331 has fully entered the heating device 1, the roller 32 on the frame 31 stops rotating. The push drive 41 drives the pusher 42 to rise, so that the pusher block 422 contacts the reinforcing bar that is not aligned with the clearance hole 331. Using the inclined surface on the pusher block 422, the reinforcing bar slides along the inclined surface until it slides into the groove 321 aligned with the clearance hole 331. When the reinforcing bar is aligned with the clearance hole 331, the roller 32 continues to rotate, driving the reinforcing bar aligned with the clearance hole 331 to move towards the heating device 1. The alignment component 5 can readjust the reinforcing bar as needed before it enters the heating device 1 to ensure that the reinforcing bar can enter the heating device 1 synchronously. When all the reinforcing bars have entered the heating device 1, the newly shot-blasted reinforcing bars from the shot blasting device 2 are conveyed by the roller 32 of the paper feeding frame 31 to continue the next feeding. This allows for seamless integration of shot blasting equipment 2 and heating equipment 1, reducing the waiting time of heating equipment 1. It effectively solves the problem of the mismatch between the capacity of shot blasting equipment 2 and the feeding capacity of medium-frequency heating equipment 1 in the existing equipment, which limits the number of shots blasted by shot blasting equipment 2, and improves the production efficiency of the entire epoxy coated steel bar production line.
