Technical Field

[0001] This invention belongs to the field of bolt processing technology, and specifically relates to a drying device for bolt production. Background Technology

[0002] After the bolts are threaded, they need to undergo quenching and tempering processes to improve their strength. Before quenching and tempering, the oil on the bolt surface needs to be cleaned. To shorten the overall processing time of the bolts, after cleaning, the bolt surface needs to be dried using a drying device.

The drying chamber is a long strip-shaped box running left and right. A left and right-oriented conveyor belt is installed inside the drying chamber, which transports bolts from left to right. A feeding channel is provided at the top of the drying chamber, feeding bolts one by one to the conveyor belt. The feeding channel is close to the left end of the conveyor belt. A suction pipe is provided at the left end of the drying chamber, which is connected to a suction fan. A hot air blowing pipe is provided at the right end of the drying chamber, which is connected to a hot air blower.

[0004] However, in the above-mentioned technical solutions, when the cleaned bolts are fed into the conveyor belt, the workpiece basket containing the bolts is generally fed into the conveyor belt by tilting it with a robotic arm. However, during the tilting process, the bolts will stack together, thus blocking each other. As a result, the moisture on the surface of the bolts that are blocked cannot fully contact the hot air, thereby affecting the overall drying efficiency of the bolts. Summary of the Invention

[0005] The purpose of this invention is to provide a drying device for bolt production, which aims to solve the problem of poor drying efficiency caused by the stacking of bolts when feeding bolts in the existing long bolt dryer.

[0007] A further technical solution of the present invention is that a sliding column is provided on the upright plate, the sliding column extends along the width direction of the vibrating plate and passes through multiple partitions, the partitions can slide on the sliding column, a second elastic element is provided between each partition, and an adjusting screw is provided on one side of the machine body, the end of the adjusting screw located inside the machine body abuts against one side of the partition.

[0008] A further technical solution of the present invention is that the second elastic element is a long strip-shaped elastic piece, the second elastic element is installed at an inclination, one end of the feeding unit is lower than the other end, and the threaded part of the bolt can contact the second elastic element.

[0009] A further technical solution of the present invention is that multiple second elastic elements are provided, which are arranged in an array along the length direction of the partition, and a gap is left between two adjacent second elastic elements.

[0010] A further technical solution of the present invention is that the partition plate is provided with an installation groove, the installation groove is provided with a water-absorbing component, the partition plate is provided with a pressure plate for fixing the water-absorbing component, an opening is provided on one side of the pressure plate, the opening is located between two second elastic components, and the water-absorbing component will protrude from the opening through its own elasticity under the action of the pressure plate, so that the bolt can contact the water-absorbing component.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-9 The present invention provides the following technical solution: a drying device for bolt production, comprising a body 1, a drying unit 2, a feeding unit 3 and a conveying unit 4.

[0032] The feeding unit 3 is located at one end of the machine body 1, and the conveying unit 4 is located inside the machine body 1 and cooperates with the feeding unit 3 so that the material on the feeding unit 3 can fall onto the conveying unit 4 by gravity. The conveying unit 4 extends from one end close to the feeding unit 3 to the other end inside the machine body 1 and is used for unloading the bolts after drying. The drying unit 2 is located above the machine body 1 and can blow hot air towards the conveying unit 4 to dry the bolts. The dried bolts will be conveyed to the end of the machine body 1 away from the feeding unit 3 by the conveying unit 4 for unloading.

[0033] A windproof shell 11 is provided on the body 1 and on both sides of the drying unit 2, and a sealing curtain is provided on the windproof shell 11. The drying unit 2 and the windproof shell 11 can cover most of the area of ​​the conveying unit 4, which can reduce the leakage of hot air and is more conducive to energy saving.

[0034] Please see Figure 2 and Figure 3 The feeding unit 3 is located outside the drying unit 2 and the windproof shell 11, facilitating the feeding of bolts. The feeding unit 3 includes two rollers 31, on which a mesh belt 32 is installed. The mesh belt 32 is woven from metal wires, forming a grid between the wires for drainage. The size of this grid is large enough to intercept bolts. The two rollers 31 inside the mesh belt 32 expand it. A drive unit 33 is installed on the machine body 1. This drive unit 33 is a geared motor, which can be connected to the rollers 31 through a sprocket structure or other transmission method to drive the rollers 31 to rotate. When a bolt is placed on the mesh belt 32, most of the cleaning liquid will be discharged from the grid of the mesh belt 32 and collected from the bottom of the machine body 1. At the same time, the bolt is intercepted on the mesh belt 32. Through the rotation of the rollers 31, the mesh belt 32 is moved, which can transport the bolts on the mesh belt 32 to the conveying unit 4. Thus, the setting of the feeding unit 3 can achieve a preliminary separation of the cleaning liquid and the bolts.

[0035] Please see Figure 2 and Figure 5The conveying unit 4 includes a vibrating plate 41 located inside the machine body 1. The vibrating plate 41 is arranged horizontally, with its length direction consistent with the length direction of the machine body 1. One end of the vibrating plate 41 is located below the feeding unit 3, allowing the bolts on the feeding unit 3 to rest on the vibrating plate 41. A first elastic element 42, which is a compression spring, is provided below the vibrating plate 41. One end of the compression spring is vertically fixed to the bottom of the vibrating plate 41, and the other end is fixedly connected to the interior of the machine body 1. A vibration motor 43 is provided at the bottom of the vibrating plate 41. When the vibration motor 43 is started, it can drive the vibrating plate 41. When vibration occurs, the bolts fall onto the vibrating plate 41 and accumulate on it. The vibration of the vibrating plate 41 can spread out the accumulated bolts. At the same time, the vibration of the vibrating plate 41 can move the bolts away from the feeding unit 3 and make them pass through the drying unit 2 and the interior of the windproof shell 11 to dry the bolts. Meanwhile, the vibration of the vibrating plate 41 will cause the bolts to shake, which can shake off some of the residual moisture on the bolt surface and improve the drying efficiency. When the bolts move to the end of the vibrating plate 41 away from the feeding unit 3, the bolts can be unloaded through the unloading plate 5.

[0036] Please see Figure 5 and Figure 8 A vertical plate 44 is provided on one side of the vibrating plate 41, forming an L-shape with the vibrating plate 41. Multiple partitions 45 are slidably arranged on the vibrating plate 41, all of which are upright. The upper surface of each partition 45 is on the same plane as the vertical plate 44, and there is a gap between each partition 45. This gap is larger than the diameter of the threaded portion but smaller than the diameter of the nut portion. Each partition 45 has a certain thickness, greater than the diameter of the nut portion of the bolt minus the diameter of the threaded portion. Due to the partitions 45, the feeding unit 3 can feed bolts onto the top of the partitions 45. At this time, the bolts accumulate at one end of the partitions 45. When the vibrating motor 43 is started, the vibrating plate 41 drives the partitions 45 to vibrate. Initially, the accumulated bolts are vibrated by the high-frequency vibration of the partitions 45. During the spreading process, the threads of the bolts will fall between the two partitions 45, while the nuts will overlap on the upper surfaces of the two partitions 45. When the bolts are laid flat, the horizontal contact area is large, which can easily lead to overlapping. By setting the partitions 45, the bolts are placed upright, significantly reducing the horizontal contact area and the probability of overlapping. This effectively reduces the stacking phenomenon and makes the bolts dry more evenly. In addition, the cleaning fluid dripping from the bolts will fall onto the vibrating plate 41. The partitions 45 will lift the bolts away from the vibrating plate 41, preventing the bolts from contacting the cleaning fluid on the vibrating plate 41 and preventing the dried surface from being contaminated with cleaning fluid again. At the same time, the thickness of the partitions 45 ensures that the nuts on adjacent bolts will not interfere with each other when they move.

[0037] Please see Figure 6The upper surfaces of the multiple partitions 45 are horizontally arranged, allowing the bolts to move forward stably and at a uniform speed. The vibrating plate 41 is inclined, with one end closer to the feeding unit 3 being lower than the other end, so that the water shaken off the bolts falls onto the vibrating plate 41 and flows through the inclined surface of the vibrating plate 41, promoting the drainage of water from the inclined surface of the vibrating plate 41.

[0038] Please see Figure 5 and Figure 8 Multiple partitions 45 can slide on the vibrating plate 41 along its width direction. A sliding post 441 is provided on the upright plate 44, extending along the width direction of the vibrating plate 41 and penetrating multiple partitions 45. This allows the partitions 45 to slide on the sliding post 441, while also limiting the sliding of the partitions 45 to prevent them from falling off the vibrating plate 41. A second elastic element 46 is provided between each partition 45. An adjusting screw 6 is provided on one side of the machine body 1, with one end of the adjusting screw 6 extending into the machine body 1 and abutting against the side of the outermost partition 45. During use, rotating the adjusting screw 6 pushes the outermost partition 45 to slide on the vibrating plate 41. When the outermost partition 45 moves, the second elastic element 46 between adjacent partitions causes multiple partitions 45 to move synchronously and equidistantly, thus allowing for equidistant adjustment of the gap between the partitions 45 to accommodate bolts of different sizes.

[0039] A handle 61 is provided at one end of the adjusting screw 6 located outside the machine body 1, which facilitates manual adjustment. A nut 63 is threaded onto the adjusting screw 6. After the distance between the partitions 45 is adjusted, the nut 63 abuts against the side wall of the machine body 1 to fix the adjusting screw 6, preventing the adjusting screw 6 from rotating due to equipment vibration and thus increasing the distance between the partitions 45. A ball bearing 62 is provided at the end of the adjusting screw 6 away from the handle 61. The ball bearing 62 abuts against the partition 45. When the partition 45 vibrates, the ball bearing 62 can rotate, which can reduce the friction between the adjusting screw 6 and the partition 45 and prevent the vibration of the partition 45 from causing the adjusting screw 6 to shake and the nut 63 to loosen.

[0040] Please see Figure 6The second elastic element 46 is a long strip-shaped spring sheet, installed in the same direction as the length of the partition 45. The second elastic element 46 is installed at an angle, with one end of the feeding unit 3 lower than the other end, and the threaded part of the bolt can contact the second elastic element 46. When the bolt moves forward, the threaded part of the bolt will first be vertically positioned between the two partitions 45. Through the uniform movement of the bolt, the threaded part of the bolt contacts the second elastic element 46, and the nut part of the bolt rests on the upper surface of the partition 45, while the threaded part rests on the second elastic element 46, causing the bolt to change from a vertical state to an inclined state. In the inclined state, the blind area of ​​the contact position between the bolt and the partition 45 can be exposed, effectively avoiding the problem of uneven drying caused by the drying blind area. In addition, due to the inclined setting of the second elastic element 46, the inclination angle of the bolt will continuously increase during the movement. The continuous change of the bolt angle makes the drying more uniform and improves the drying effect.

[0041] Multiple second elastic elements 46 are arranged in an array along the length of the partition 45, with a gap between each adjacent second elastic element 46. At the same time, the tilt angles of the multiple second elastic elements 46 are consistent, and their tilting surfaces are all on the same plane. When the threaded part of the bolt moves above the second elastic element 46 and is tilted, one end of the second elastic element 46 contacts the middle of the bolt threaded part and generates a large frictional force, thereby slowing down the movement speed of the bolt. In this way, the bolt above the second elastic element 46 and the bolt between the two second elastic elements 46 can be spaced apart, avoiding the problem of bolts crowding each other and making it difficult for hot air to directly contact the bolt threaded part.

[0042] One end of the second elastic element 46 is provided with a rounded corner. The size of the rounded corner should be greater than the bolt pitch to avoid the problem that one end of the second elastic element 46 gets stuck in the bolt thread, making it difficult for the bolt to move forward.

[0043] Please see Figure 7 and Figure 9A mounting groove 451 is provided on the partition 45, and a water-absorbing component 452 is installed inside the mounting groove 451. A pressure plate 453 is provided on the partition 45, and the pressure plate 453 fixes the water-absorbing component 452 inside the mounting groove 451 by screws. An opening 454 is opened on one side of the pressure plate 453, and the opening 454 is located between two second elastic members 46. The water-absorbing component 452 is a sponge. Under the action of the pressure plate 453, most of the volume of the water-absorbing component 452 is fixed inside the mounting groove 451. A small portion of the volume protrudes outside the opening 454 due to the elasticity of the water-absorbing component 452, allowing the water-absorbing component 452 to come into contact with the bolt as it passes through, thereby wiping away the moisture on the bolt surface and improving drying efficiency. A ventilation slot is also provided above the pressure plate 453, which corresponds to each water-absorbing component 452, allowing hot air to act on the top of the water-absorbing component 452 to dry and evaporate the moisture adsorbed on the water-absorbing component 452.

[0044] Please see Figure 3 and Figure 9 Multiple thin horizontal abutments 455 are provided on the side of the partition 45 away from the pressure plate 453, and the abutments 455 are arranged one-to-one with the water-absorbing element 452. When the bolt passes through the water-absorbing element 452, one side of the bolt contacts the water-absorbing element 452, and the other side abuts against the abutment 455. The abutment 455 can laterally limit the bolt, forcing the bolt to be closer to the water-absorbing element 452, effectively improving the wiping and cleaning effect of the water-absorbing element 452 on the surface of the bolt. At the same time, the contact area between the bolt and the water-absorbing element 452 is larger than the contact area between the bolt and the abutment 455, so that the friction between the bolt and the water-absorbing element 452 is significantly greater than the friction with the abutment 455.

[0045] When the bolt moves between the two second elastic elements 46, the vertical bolt moves towards the water-absorbing element 452 under the action of vibration and the push of the bolt behind it. During the process, it rotates by means of the frictional difference between the bolt and the water-absorbing element 452. When the bolt moves above the second elastic elements 46, the blind area at its bottom that was originally difficult to be dried by hot air will be fully exposed to the hot air environment with the rotation, which completely avoids the problem of uneven heating in some areas. This ensures that the bolt threads and all areas of the surface are dried evenly, which greatly improves the drying efficiency and drying quality. At the same time, the water-absorbing element 452 can thoroughly wipe away residual oil or moisture on the bolt surface, laying a good foundation for the subsequent drying process. Ultimately, it ensures the surface cleanliness and drying consistency of the bolt, which is conducive to improving the overall assembly accuracy and service life of the product.
