Description

Technical Field

[0001] This utility model relates to a feeding device, and more particularly to a rod feeding device. Background Technology

[0002] In the installation of large equipment, such as wind turbines, the components are enormous, requiring the use of large bolts. During the machining of these bolts, especially in the head machining process, metal rods are often manually clamped and heat-treated using magnetic induction heating before being stamped to form the bolt head. However, this traditional manual method is inefficient, produces inconsistent quality, and poses certain safety hazards. Therefore, the inventors have developed a feeding device (already filed separately) that enables automatic arrangement, conveying, and heating of the rods. Since rods of different specifications have varying lengths and diameters, precise control of the rod feeding position is necessary to enable the conveying device to adapt to different lengths of rods. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rod feeding device that is compact in structure, small in size, low in manufacturing cost, can effectively realize the automatic arrangement and feeding of rods, and whose feeding position and width are precisely adjustable.

[0004] This utility model provides a rod feeding device, which includes:

[0005] The slide table is provided with a ramp;

[0006] Support frames are installed on both sides of the slide table;

[0007] At least two mounting shafts are detachably mounted between the two support frames, and the length direction of the mounting shafts 3 is parallel to the width direction of the slope;

[0008] There are two side baffles I, which are mounted on the mounting shaft. A discharge area is formed between the two side baffles I. The side baffles I can slide along the axial direction of the mounting shaft and the position and width of the discharge area can be adjusted.

[0009] A guide plate is installed on the mounting shaft and located between the two side baffles I. The bottom surface of the guide plate has a gap with the slope to form a guide channel. The guide channel is arc-shaped and can accommodate a single rod material to pass through laterally. The discharge direction of the guide channel is set vertically downward or inclined downward.

[0010] This application utilizes a sliding table where rods are placed and slide down an incline under their own weight, eliminating the need for additional motors or complex drive mechanisms. This significantly simplifies the device structure and reduces manufacturing costs, energy consumption, and maintenance requirements. The side baffle I features a sliding and adjustable design, allowing the position and width of the discharge area to be flexibly adjusted according to different rod specifications. This ensures the rods accurately enter subsequent processing positions in a preset posture, offering high flexibility. The guide channel employs an arc-shaped structure, enhancing the guidance and stability of the rods during sliding, preventing deflection and tilting at both ends during transport, and avoiding jamming. Simultaneously, it ensures the rods at the discharge end enter the downstream screw conveyor in a near-horizontal state, guaranteeing the continuity and stability of rod transport. The mounting shaft is detachable, enabling quick replacement of the side baffle I and guide plate to accommodate different rod specifications, further improving the device's versatility and practicality.

[0011] Furthermore, the angle between the discharge direction of the guide channel and the horizontal plane is greater than or equal to 80 degrees and less than or equal to 90 degrees. The near-vertical angle of the discharge direction of the guide channel maximizes the component of gravity in the discharge direction, which provides the strongest driving force for the rod to leave the guide channel. This effectively overcomes the slight friction or adhesion that may exist between the material and the channel wall, ensuring that the material can leave the outlet smoothly and quickly without stagnation, avoiding accumulation or jamming at the outlet. At the same time, the near-vertical channel forces the rod to keep its axis horizontal or nearly horizontal when leaving the outlet, which greatly improves the success rate of the rod being reliably received and accurately positioned by downstream equipment, and reduces the misalignment problem caused by incorrect posture.

[0012] Furthermore, the lower end of the slide table is provided with a clearance area for installing the screw conveyor. The discharge end of the guide channel faces the clearance area, which provides a dedicated installation space for the screw conveyor, allowing the two independent functional mechanisms to be compactly integrated into one, shortening the rod material transfer path. After leaving the guide channel, the rod material falls directly into the receiving area of ​​the screw conveyor, eliminating intermediate transfer links. The structure is compact and occupies little space.

[0013] Furthermore, the screw conveying device includes at least two horizontally arranged screws that can rotate synchronously. The upper surface of the screws forms a conveying surface, which causes the rod material to tend to move axially towards the first side. The first side of the conveying surface is provided with a limiting component, which can contact the first end of the rod material and axially limit it so that the second end of the rod material protrudes outside the conveying surface at a set length for induction heating. The conveying direction of the conveying surface is perpendicular to the rod material in the guide channel, and the discharge end of the guide channel is located above the feed end of the conveying surface. By using multiple screws to form the conveying surface, continuous and stable conveying of the rod material can be achieved. At the same time, the limiting component is provided to precisely control the extension length of the rod material, ensuring the consistency of the heating area and the matching of process requirements.

[0014] Furthermore, it also includes a fixed bracket, on which both the slide table and the screw conveyor are mounted, and the slide table and the fixed bracket are insulated from each other, as are the screw conveyor and the fixed bracket. The slide table and the screw conveyor are mounted on the same fixed bracket, forming a common reference positioning system and an integral structure, avoiding the risk of vibration misalignment caused by separate installation. At the same time, the insulated installation avoids the formation of a circuit that would generate induced current during induction heating, thus improving the safety of use.

[0015] Furthermore, the ramp has a downwardly concave arc surface I and an upwardly convex arc surface II tangent to the lower end of the arc surface I. The radius of the arc surface I is greater than the radius of the arc surface II. The double arc surface structure design can effectively control the kinetic energy and end posture of the rod in the guide channel, ensuring smooth movement of the rod in the guide channel and the discharge accuracy.

[0016] Furthermore, the central angle formed by the arc surface I is greater than or equal to 70 degrees and less than 90 degrees, and the central angle formed by the arc surface II is greater than or equal to 60 degrees and less than 80 degrees.

[0017] Furthermore, the guide plate is slidably mounted on the mounting shaft and fixed with bolts.

[0018] Furthermore, there are at least two guide plates, which can form a more stable guide channel with the slope, ensuring the centering and stability of the rod material during the conveying process and avoiding tilting.

[0019] Furthermore, it also includes a detection sensor facing the material guide channel and used to detect the rod material within the material guide channel. The detection sensor can automatically detect the rod material within the material guide channel, provide timely feedback on the material condition, avoid idling, and ensure the continuity and stability of equipment operation.

[0020] Furthermore, the detection sensor is mounted on the mounting shaft and located at the feed end of the material guide channel, and a window corresponding to the detection sensor is provided on the slope.

[0021] Furthermore, the feed end of the material guide channel is widened to form a feed guiding structure, which can effectively improve the smoothness of the rod material entering the material guide channel and reduce the risk of material jamming.

[0022] Furthermore, the support frame, the side baffle I, and the guide plate are all equipped with clamping blocks that allow the installation shaft to pass through and be clamped by bolts. The clamping block design facilitates the quick clamping and positioning of the installation shaft, ensuring the stability and reliability of the overall structure, and enabling quick loading, unloading, and position adjustment.

[0023] Furthermore, a side baffle II is fixedly installed on one side of the slope for calibrating or limiting the side baffle I at that end. The side baffle II can serve as a reference end for the second side, enabling rapid and precise adjustment of the side baffle I at that end.

[0024] Furthermore, the support frame includes a first rod and a second rod connected to each other. The plane formed by the first rod and the second rod is perpendicular to the length direction of the mounting shaft. The first rod and the second rod are provided with a first clamping block for mounting the mounting shaft. The lower end of the first rod or the second rod is provided with a mounting seat for connecting to the side wall of the slide.

[0025] This utility model's rod feeding device features a sliding table, allowing the rods to slide down an incline under their own weight. This eliminates the need for additional motors or complex drive mechanisms, significantly simplifying the device structure and reducing manufacturing costs, energy consumption, and maintenance requirements. The side baffle I is adjustable, allowing the position and width of the discharge area to be flexibly adjusted according to different rod specifications, ensuring the rods accurately enter subsequent processing positions in a preset posture, offering high flexibility. The guide channel employs an arc-shaped structure, enhancing the guidance and stability of the rods during sliding, preventing deflection and tilting at both ends during transport. The device effectively clamps the material while ensuring that the rod material at the discharge end enters the downstream screw conveyor in a near-horizontal state, thus guaranteeing the continuity and stability of the rod material conveying. The mounting shaft adopts a detachable structure, allowing for quick disassembly and replacement of the side baffle I and guide plate to adapt to the feeding requirements of rod materials of different specifications, further improving the versatility and practicality of the device. This utility model rod material feeding device has a compact structure, low manufacturing cost, and convenient loading, unloading, and adjustment. It can achieve stable feeding of rod materials of different specifications, providing reliable feeding assurance for downstream induction heating, and effectively improving overall production efficiency and automation level.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] See Figures 1-8 This utility model provides a rod feeding device for continuous and stable feeding of rods, which includes a slide table 1, a support frame 2, a side baffle 14 and a guide plate 5.

[0037] The slide table 1 is the main body, which includes two side plates 11 and a ramp 12 set between the two side plates 11. The ramp 12 is an inclined surface that serves as the working surface. The ramp 12 is arc-shaped, and the support frame 2 is symmetrically installed on both sides of the slide table 1.

[0038] There are at least two mounting shafts 3, which are set on one side of the working surface of the slide table 1. The mounting shafts 3 are detachably installed between the two support frames 2. The length direction of the mounting shafts 3 is parallel to the width direction of the ramp 12, that is, parallel to the line connecting the two support frames 2. The mounting shafts 3 serve as the mounting carriers for the side baffle I4 and the guide plate 5.

[0039] There are two side baffles I4, which are mounted on the mounting shaft 3. A discharge area is formed between the two side baffles I4, and the side baffles I4 can slide along the axial direction of the mounting shaft 3, thereby adjusting the position and width of the discharge area. A guide plate 5 is mounted on the mounting shaft 3 and located between the two side baffles I4. There is a gap between the bottom surface of the guide plate 5 and the ramp 12, forming a guide channel 102. The guide channel 102 is arc-shaped and can allow a single rod to pass through laterally. That is, when feeding, the movement direction of the rod is perpendicular to the axial direction of the rod. At the same time, the discharge direction of the guide channel 102 is set vertically downward or inclined downward.

[0040] This application simplifies the device structure and reduces manufacturing costs, energy consumption, and maintenance requirements by setting up a sliding table on which the rod material is placed and slides down the slope under its own weight. This eliminates the need for additional motors or complex drive mechanisms. The side baffle I features a sliding and adjustable design, allowing the position and width of the discharge area to be flexibly adjusted according to different rod material specifications. This ensures the rod material accurately enters the subsequent processing station in a preset posture, offering high flexibility. The guide channel adopts an arc-shaped structure, improving the guidance and stability of the rod material during sliding, preventing deflection and tilting at both ends during transport, and avoiding jamming. Simultaneously, it ensures that the rod material at the discharge end enters the downstream screw conveyor in a near-horizontal state, thus guaranteeing the continuity and stability of rod material transport. The mounting shaft adopts a detachable structure, enabling quick disassembly and replacement of the side baffle I and the guide plate to adapt to the feeding requirements of different rod material specifications, further improving the device's versatility and practicality.

[0041] To improve feeding smoothness, the feeding end of the guide channel 102 is widened to form a feeding guide structure. The feeding guide structure can effectively improve the smoothness of the rod material entering the guide channel 102 and reduce the risk of jamming. Specifically, the feeding end of the guide plate 5 is provided with an inclined surface 52. The inclined surface 52 makes the feeding end of the guide channel 102 form a feeding guide structure with a small upper end and a small lower end, which facilitates rapid feeding and avoids feeding errors from affecting feeding efficiency and stability.

[0042] In this application, the ramp 12 has an arc-shaped surface I 12a and an arc-shaped surface II 12b. The arc-shaped surface I 12a is a downwardly concave arc-shaped structure, and the arc-shaped surface II 12b is located at the lower end of the discharge end of the arc-shaped surface I 12a. The two are tangent to each other, and the arc-shaped surface II 12b is an upwardly convex arc-shaped structure. The radius of the arc-shaped surface I 12a is greater than the radius of the arc-shaped surface II 12b. The double arc-shaped surface structure design can effectively control the kinetic energy and end posture of the rod in the guide channel 102, ensuring the smooth movement of the rod in the guide channel 102 and the discharge accuracy. Preferably, the central angle formed by the arc-shaped surfaces I 12a is greater than or equal to 70 degrees and less than 90 degrees, while the central angle formed by the arc-shaped surfaces II 12b is greater than or equal to 60 degrees and less than 80 degrees.

[0043] In this application, the angle between the discharge direction of the guide channel 102 and the horizontal plane is greater than or equal to 80 degrees and less than or equal to 90 degrees. The discharge direction of the guide channel 102 is close to a vertical angle, which maximizes the component of gravity in the discharge direction. This provides the strongest driving force for the rod to leave the guide channel 102, effectively overcoming any minor friction or adhesion between the material and the channel wall, ensuring that the material can leave the discharge port smoothly and quickly without any stagnation, and avoiding accumulation or jamming at the outlet. At the same time, the near-vertical channel forces the rod to keep its axis horizontal or nearly horizontal when leaving the outlet, which greatly improves the success rate of the rod being reliably received and accurately positioned by downstream equipment, and reduces misalignment problems caused by incorrect posture.

[0044] A clearance area is provided at the lower end of the slide table 1 for installing the screw conveyor 8, and the discharge end of the guide channel 102 faces the clearance area. The clearance area provides dedicated installation space for the screw conveyor 8, so that the two independent functional mechanisms are compactly integrated into one, shortening the rod material transmission path. After the rod material leaves the guide channel 102, it falls directly into the receiving area of ​​the screw conveyor 8, eliminating intermediate transfer links. The structure is compact and occupies little space. Specifically, the screw conveyor 8 includes at least two horizontally arranged screws that can rotate synchronously. The upper surface of the screws forms a conveying surface for conveying the rod material. During the conveying process, the conveying surface causes the rod material to tend to move axially towards the first side, which is achieved through friction between the screws and the rod material. At the same time, a limiting component is provided on the first side of the conveying surface. This limiting component can contact the first end of the rod material and axially limit it, thereby causing the second end of the rod material to protrude outside the conveying surface at a set length for induction heating. The conveying direction of the conveying surface is perpendicular to the rod material in the guide channel 102. The discharge end of the guide channel 102 is located above the feed end of the conveying surface. By using multiple screws to form the conveying surface, continuous and stable conveying of the rod material can be achieved. At the same time, the limiting component is equipped to precisely control the extension length of the rod material, ensuring the consistency of the heating area and the matching of process requirements.

[0045] To improve overall integrity, this application also includes a fixed bracket 7, on which the slide table 1 and the screw conveyor 8 are both mounted. Furthermore, there is insulation between the slide table 1 and the fixed bracket 7, and between the screw conveyor 8 and the fixed bracket 7. The slide table 1 and the screw conveyor 8 are mounted on the same fixed bracket, forming a common reference positioning system and an integrated structure. This avoids the risk of vibration misalignment caused by separate installations. Additionally, the insulated installation prevents the formation of a circuit that could generate induced current during induction heating, thus improving safety.

[0046] In this application, the guide plate 5 is slidably mounted on the mounting shaft 3 and fixed with bolts, thereby enabling sliding adjustment. There are at least two guide plates 5, preferably arranged on both sides of the guide channel 102 to ensure the centering and stability of the rod material during the conveying process and to avoid tilting.

[0047] In this application, clamping blocks are provided on the support frame 2, the side baffle I4 and the guide plate 5. The clamping blocks can accommodate the installation shaft 3 to pass through and can be fixed by bolt clamps. The clamping block design facilitates the quick clamping and positioning of the installation shaft, ensures the stability and reliability of the overall structure, and enables the quick loading, unloading and position adjustment of the whole.

[0048] To achieve rapid positioning, in this application, a side baffle II 13 is fixedly installed on one side of the ramp 12. Specifically, the side baffle II 13 is set on the second side, that is, the side opposite to the movement trend of the rod on the conveying surface. The side baffle II 13 is used to calibrate or limit the side baffle I 4 at this end. The side baffle II can serve as the reference end of the second side, enabling rapid and precise adjustment of the side baffle I at this end.

[0049] In this application, the support frame 2 includes a first rod 21 and a second rod 22 connected to each other. The plane formed by the first rod 21 and the second rod 22 is perpendicular to the length direction of the mounting shaft 3. A first clamping block I 211 is fixedly installed at the end of the first rod 21, and a first clamping block II 221 is fixedly installed at the end of the second rod 22, allowing for quick loading and unloading of the mounting shaft 3. In this embodiment, the first rod 21 is vertically arranged, and the second rod 22 is horizontally arranged in the discharge direction. A reinforcing rod 24 is provided between the first rod 21 and the second rod 22. A mounting seat 231 is provided at the lower end of the first rod 21 or the second rod 22. In this embodiment, a mounting rod 23 is fixed at the end of the first rod 21. The mounting rod 23 faces the slide table 1 and is perpendicular to both the first rod 21 and the second rod 22. A mounting seat 231 with a mounting hole is fixed at the end of the mounting rod 23 for fixed connection with the side wall of the slide table 1.

[0050] To improve the continuity of material feeding and avoid empty running at the back end due to empty material, this application also provides a detection sensor 6. The detection sensor 6 faces the material guide channel 102 and is used to detect the rod material in the material guide channel 102. The detection sensor 6 can automatically detect the rod material in the material guide channel 102, provide timely feedback on the material status, avoid empty running, and ensure the continuity and stability of equipment operation. Specifically, the detection sensor 6 is installed on the mounting shaft 3 and located at the feed end of the material guide channel 102. At the same time, a window 120 corresponding to the detection sensor 6 is opened on the ramp 12 to allow the detection signal of the detection sensor 6 to pass through.

[0051] This utility model's rod feeding device features a sliding table, allowing the rods to slide down an incline under their own weight. This eliminates the need for additional motors or complex drive mechanisms, significantly simplifying the device structure and reducing manufacturing costs, energy consumption, and maintenance requirements. The side baffle I is adjustable, allowing the position and width of the discharge area to be flexibly adjusted according to different rod specifications, ensuring the rods accurately enter subsequent processing positions in a preset posture, offering high flexibility. The guide channel employs an arc-shaped structure, enhancing the guidance and stability of the rods during sliding, preventing deflection and tilting at both ends during transport. The device effectively clamps the material while ensuring that the rod material at the discharge end enters the downstream screw conveyor in a near-horizontal state, thus guaranteeing the continuity and stability of the rod material conveying. The mounting shaft adopts a detachable structure, allowing for quick disassembly and replacement of the side baffle I and guide plate to adapt to the feeding requirements of rod materials of different specifications, further improving the versatility and practicality of the device. This utility model rod material feeding device has a compact structure, low manufacturing cost, and convenient loading, unloading, and adjustment. It can achieve stable feeding of rod materials of different specifications, providing reliable feeding assurance for downstream induction heating, and effectively improving overall production efficiency and automation level.

[0052] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
