Description

Technical Field

[0002] In order to improve the overall performance of the bolts, in addition to optimizing the process during bolt production, the surface of the produced bolts also needs additional processing. The hot-dip galvanizing process can coat a layer of zinc on the surface of the bolts, which can improve the anti-corrosion performance of the bolts. Hot-dip galvanized products often have a low coating hardness, and the surface is easily scratched during transportation, processing, and use, which reduces the protective performance of the coating and the surface appearance quality. In order to increase the hardness of the hot-dip galvanized coating, a nano-composite coating is often applied on the surface of the product to improve the hardness of the zinc coating.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. A spray coating component is provided. By pushing the electric push rod to drive the push rod to contract, the push rod drives the rotating disk to move along the supporting slide rod. The rotating disk compresses the clamping spring and the return spring during the movement. Under the pull of the clamping rope and the push baffle, the gap between the four clamping plates on the clamping disk expands, and the clamping mechanical arm is used to clamp the bolt to the middle of the four clamping plates on the clamping disk. After fixing, the electric push rod is pushed to drive the push rod to return to its original position, and the return spring and the clamping spring are extended. Under the rebound action of the spring hinge seat, the clamping plate clamps the bolt and The conveying motor drives the gear chain to move, and the bolts pass through the bottom of the coating nozzle in turn. Under the meshing action of the rotating gear and the rotating rack, the rotating disk rotates around the supporting slide rod during the movement. In conjunction with the operation of the electric slide rail and the adjusting electric push rod, the coating nozzle sprays the solution to coat the surface of one end of the bolt. After one end is sprayed, the other end is sprayed to complete the processing of the bolt. During the processing, the bolt moves and rotates at the same time, so that the sprayed solution can be evenly sprayed on the bolt surface, avoiding the generation of spraying dead angles and improving the processing quality of the bolt;

[0022] At the same time, the gear chain drives the support seat to move back and forth, and can continuously process the bolts one by one, so that the quality of spraying is guaranteed. At the same time, by controlling the telescopic length of the output end of the push electric push rod, the moving distance of the rotating disk on the supporting slide rod can be controlled, and then the expansion space of the four clamping plates on the clamping disc can be controlled, so that the device can be used for bolts of different diameters and has a wide range of applications. At the same time, the assembly seat is driven to move by the adjusting cylinder, so that the spacing between the clamping plates on one side of the two assembly seats is greater than the length of the bolt to be processed. The system can be flexibly adjusted according to the length of the processed bolt, further increasing the scope of application.

[0023] 2. A drying and discharging assembly is provided. When the rotating gear moves to the bottom of the first air collecting box and contacts the rotating rack, the air delivery pump delivers air to the inside of the first air collecting box. The air is heated by the electric heating wire and then ejected through the air jet. The ejected hot air dries the surface of the bolt, so that the nano solution is fully attached to the surface of the bolt. There is no need to transfer the bolt in the middle to dry the bolt. At the same time, under the connection drive of the linkage frame, the electric push rod is adjusted to drive the first air collecting box to move, so that the hot air ejected from the air jet can fully sweep the surface of the bolt, and the drying effect is better. When processing bolts of different diameters, the height of the first air collecting box and the coating nozzle can be adjusted by adjusting the lifting electric push rod, so that the coating nozzle and the bottom of the air jet are closer to the bolt surface, so that the ejected solution and hot air can better act on the bolt surface, avoiding the waste of the spraying solution while also improving the drying speed;

[0024] When the bolt is coated and moved to the middle of the transfer bottom slot and the transfer top slot, under the limiting effect of the lifting limit rod, the lifting motor drives the transfer wheels in the transfer bottom slot and the transfer top slot to clamp the bolt, and cooperates with the transfer motor. The transfer wheel drives the bolt to move and transfer the bolt, and there is no need to manually remove the bolt, which saves labor costs. At the same time, by controlling the gap between the transfer bottom slot and the transfer top slot by controlling the lifting motor, bolts of different diameters can be stably transferred, and the application range is wide. During the transfer process, the air pump delivers air to the inside of the second air collecting box, and the air is heated by the electric heating wire to perform secondary drying on the bolt, further improving product quality.

[0025] At the same time, a reflux box is provided to collect the excess nano-plating liquid sprayed from the coating nozzle, so as to prevent the nano-plating liquid from spilling everywhere and also facilitate the nano-plating machine to recycle the excess plating liquid.

[0026] To summarize, in the spray coating assembly, while the gear chain drives the bolts for spray coating, the drying and discharging assembly can dry the bolts after spray coating during the movement. Compared with the traditional method of uniformly transferring and drying the bolts using a transfer device after spraying, when this system processes the bolts, the undried coating will not contact other devices, thus avoiding the adhesion of the coating to the transfer device due to contact between the undried coating and the transfer device, thereby further improving the bolt processing quality.

[0053] The working principle and use process of the present invention are as follows: First, the bolts are placed on the top of the feeding conveyor belt 234 in sequence, and the feeding conveyor belt 234 drives the bolts to move to the bottom of the clamping end of the clamping mechanical arm 235 on one side, and the clamping mechanical arm 235 and one end push the electric push rod 229 to start, and the output end of the push electric push rod 229 drives the push rod 230 to contract, and the push rod 230 contacts the rotating disk 212 and applies thrust to the rotating disk 212, and the push rod 230 pushes the rotating disk 212 to move along the supporting slide bar 211 The rotating disk 212 moves, and during the movement, the pushing baffle 219 pushes the pushing baffle 219 to compress the clamping spring 225, and at the same time compresses the return spring 215. Under the pull of the clamping rope 218 and the pushing baffle 219, the gap between the four clamping plates 216 on the clamping disc 237 expands. At this time, the clamping mechanical arm 235 clamps the bolts on the feeding conveyor belt 234 to the middle of the four clamping plates 216 on one side of the clamping disc 237. At this time, the output end of the electric push rod 229 is extended to drive the push rod 2 30 returns to its original position, the rotating disk 212 loses the restriction of the push rod 230, the return spring 215 and the clamping spring 225 extend, and under the rebound effect of the spring hinge seat 239, the clamping plate 216 clamps the bolt. After the bolt is clamped, the conveying motor 205 is started, and the conveying motor 205 drives the conveying gear 203 to rotate, thereby driving the gear chain 206 to move, and the gear chain 206 moves to drive the support seat 210 to move. When the rotating gear 227 is connected with the first rotating rack 228, the rotating gear 227 is connected with the first rotating rack 228. When the contact is made, under the meshing action of the gears, the rotating disk 212 rotates around the supporting slide bar 211. Under the rotational connection action between the following ring 214 and the following rotating groove 213 and the rotating ring 222 and the rotating connecting groove 221, and at the same time, under the connection action between the limiting ear 223 and the limiting slide bar 220, the normal rotation of the rotating disk 212 is guaranteed. When the rotating disk 212 rotates, under the connection action of the linkage slide bar 238, the clamping disk 237 and the clamping plate 216 rotate synchronously, thereby driving the bolt to rotate.

[0054] At the same time, the external nano-spraying machine, the electric slide rail 231 and the adjusting electric push rod 232 are running, the electric slide rail 231 drives the coating nozzle 233 to move synchronously with the bolt at the bottom, and the adjusting electric push rod 232 drives the coating nozzle 233 to swing, the coating nozzle 233 sprays the solution to coat the surface of one end of the bolt, the bolt rotates during the movement, the sprayed solution can be evenly sprayed on the surface of the bolt to avoid the generation of spraying dead corners, and at the same time, the reflux box 309 can collect the excess nano-plating liquid sprayed from the coating nozzle 233 to avoid the nano-plating liquid from spilling everywhere, and at the same time, it can facilitate the nano-spraying machine to recycle the coating liquid;

[0055] When the rotating gear 227 moves to the bottom of the first air collecting box 302 and contacts the second rotating rack 228, the electric heating wire 304 and the air pump 308 inside the first air collecting box 302 are started, and the bolt moves and rotates at the same time, and the air pump 308 transports air to the first air collecting box 302. The air is heated by the electric heating wire 304 and then ejected through the air jet 303. The ejected hot air dries the surface of the bolt, so that the nano solution is fully attached to the surface of the bolt. At the same time, under the connection and drive of the linkage frame 301, the adjusting electric push rod 232 also drives the first air collecting box 302 to move, so that the hot air ejected from the air jet 303 can fully sweep the surface of the bolt, and the drying effect is better. When processing bolts of different diameters, the height of the first air collecting box 302 and the coating nozzle 233 can be adjusted by adjusting the lifting electric push rod 307, so that the coating nozzle 233 and the bottom of the air jet 303 are closer to the bolt surface, so that the ejected solution and hot air can better act on the bolt surface The surface is dried to avoid waste of the spraying liquid and improve the drying speed. The soft air hole plate 305 diverts the air flowing through, making the ejected hot air softer and preventing the hot air from blowing away the nano solution coated on the surface of the bolt. When the rotating gear 227 is disengaged from the rotating rack 228, the conveying motor 205 is suspended, and the pushing electric push rod 229 close to the first air collecting box 302 is operated, and the output end of the pushing electric push rod 229 drives the pushing rod 230 to contract, and the pushing rod 230 drives the rotating gear 227 to disengage from the rotating rack 228. The moving plate 212 moves along the supporting slide bar 211, and the clamping rope 218 pulls the clamping plate 216 to expand. At the same time, the clamping mechanical arm 235 next to it operates. When the clamping plate 216 expands, the clamping end of the clamping mechanical arm 235 clamps the bolt with one end sprayed and disengaged from the inside of the clamping plate 216. After the bolt is disengaged, the electric push rod 229 is pushed to drive the push rod 230 to return to its original position, and the rotating plate 212 also returns to its original position under the rebound of the clamping spring 225 and the return spring 215;

[0056] Then, the pushing electric push rod 229 at one end of the assembly seat 202 on the other side is started, and the pushing electric push rod 229 drives the pushing rod 230 to contract, and the clamping plate 216 expands. The clamping mechanical arm 235 of the clamping bolt will insert one end of the coated bolt into the middle of the four clamping plates 216, and the pushing electric push rod 229 drives the pushing rod 230 to return to its original position. The clamping plate 216 fixes the bolt, and repeats the previous operation steps. The conveying motor 205 drives the bolt to pass through the coating nozzle 233 and the bottom of the first air collecting box 302 on this side in turn, and the surface of the other end of the thread is sprayed and dried. When the gear chain 206 on this side drives the bolt to move to the middle of the transfer bottom groove 313 and the transfer top groove 314, the conveying motor 205 on this side is suspended, and the lifting motor 320 drives the double The screw rod 321 rotates, and under the limiting effect of the lifting limit rod 319, the lifting motor 320 drives the threaded connection ears 325 to approach each other, and the transfer wheels 315 in the transfer bottom groove 313 and the transfer top groove 314 clamp the bolts. After clamping, the transfer motor 317 is started, and the transfer wheel 315 drives the bolts to move. At the same time, the external air pump is started, and the external air pump conveys air to the inside of the second air collecting box 322. The electric heating wire 304 inside the second air collecting box 322 is started, and the air heating port flows through the connecting port 323 and contacts the bolts at the bottom to perform secondary drying of the bolts, so that the drying effect is good. Under the guidance of the transfer wheel 315, the bolts are conveyed to the top of the discharge conveyor belt 312, and the discharge conveyor belt 312 transfers the processed bolts to post-processing.

[0057] Repeat the above processing steps and process the bolts one by one continuously to ensure the quality of spraying;

[0058] At the same time, before processing the bolts, the adjusting cylinder 209 should be controlled according to the length of the two-way bolts. Under the sliding connection between the adjusting slide 208 and the adjusting slide rail 207, the adjusting cylinder 209 drives the assembly seat 202 to move, so that the distance between the clamping plates 216 on one side of the two assembly seats 202 is greater than the length of the bolt to be processed. When the gear chain 206 on one side drives the bolt to move, the bolt is prevented from colliding with the clamping plate 216 on the assembly seat 202 on the other side, thereby ensuring the normal operation of the device. By controlling the assembly seats 202 on both sides to be as close as possible to reduce the transfer distance, the clamping robot arm 235 can clamp the bolt more quickly and move it from the assembly seat 202 on one side to the assembly seat 202 on the other side, thereby shortening the bolt processing time.
