The present invention cleans the surface dust and impurities of the metal bar by putting the metal bar into the feed box, and the feed roller evenly feeds the metal bar. When the first transmission rod rotates, the travel block causes the first push rods on both sides to move back and forth inside the first piston cylinder.

[0015] 2. The present invention fully soaks the cleaned metal bars for corrosion protection. When the first transmission rod rotates, it causes the first gear on the inner wall on the other side of the second transmission belt to rotate. Then, when the second gear and the third gear rotate, the rotating block and the material transfer block rotate, so that the material transfer block intermittently transfers the metal bars washed on the rolling plate above the material rack, and at the same time, the metal bars are uniformly soaked in the soaking box.

[0016] 3. The present invention performs a secondary flushing on the metal rod after soaking. When the third gear rotates, it drives the first connecting rod installed on the side wall to make an inclined reciprocating rotation, drives the fourth gear and the fifth gear on both sides to rotate, and then the conveyor belt can be rotated, so that the rolling metal rod can be evenly rolled into a plurality of material storage troughs installed on the outer wall of the conveyor belt, and at the same time, the second push rod is caused to reciprocate up and down in the second piston cylinder. During the up and down movement, the one-way valve in the connecting pipe is closed and the one-way valve in the second water spray pipe is opened, so that the water inside the water tank is sucked in through the connecting pipe and sprayed out through the second water spray pipe, so that the metal cleaning agent and dust remaining on the surface of the metal rod after soaking can be flushed for the second time, and the anti-corrosion and anti-rust effect of the metal rod can be further improved.

[0017] 4. The present invention sprays and quickly air-dries the metal bars after secondary washing. When the conveyor belt rotates, the outer wall of the other end is driven to sleeve the third transmission belt to rotate the third transmission rod, causing the reciprocating screw to rotate. When the spraying mechanism moves, the tooth plate contacts the surface of the fan gear, and causes the fan gear to rotate on both sides, so that the fan blade plate fans the metal bars rolling above the feed plate for air drying. The metal bars after secondary washing can be quickly air-dried to facilitate subsequent spraying work, and further improve the protection of the metal bar surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] When cleaning the dust and impurities on the surface of the metal bar, after the metal bar is put into the feed box 121, the motor in the chassis 110 starts to drive the first transmission rod 122 to rotate, so that the feed roller 1294 evenly feeds the metal bar, so that the metal bar evenly falls to the rolling plate 125 and rolls on one side. When the first transmission rod 122 rotates, the first rotating disk 123 rotates synchronously, so that the travel block 126 makes the first push rods 128 on both sides reciprocate inside the first piston cylinder 127. When the first push rod 128 moves to the left inside the first piston cylinder 127, the water flow inside the water tank 1293 is driven to circulate through the water inlet pipe 1292 connected at one end until the water flows into the first piston cylinder 127. When the first push rod 128 moves to the right inside the first piston cylinder 127, the first piston cylinder 127 When the internal water flow is replenished, the one-way valve in the water inlet pipe 1292 is closed and the one-way valve in the first water spray pipe 1291 is opened, causing water to be sprayed out through the flushing head connected to one end of the first water spray pipe 1291, and flushing the surface dust and impurities of the metal rods rolling above the rolling plate 125, causing the dust and impurities on the surface of the metal rods to fall into the recycling box, and the filter net in the recycling box can filter the dust and impurities. The filtered water then flows into the water storage tank 1293 connected to the other end of the recycling box through the return pipe, completing the cleaning of the dust on the surface of the metal rods to prevent adhesion while avoiding the waste of water resources.

[0024] Please refer to Figure 5 and Figure 6The intermittent feeding soaking component 140 includes a second transmission belt 141 fixedly mounted on the outer wall of the first transmission rod 122, a second transmission rod 142 fixed to the end of the side wall of the soaking box 130 is mounted on the inner wall of the other side of the second transmission belt 141, a first gear 143 is fixedly mounted on the other end of the second transmission rod 142, a second gear 144 and a third gear 145 at a surface contact position with the first gear 143 are mounted on the side wall bearing of the soaking box 130, a rotating block 146 penetrating and extending to the inner wall of the soaking box 130 is mounted on the side wall of each group of the second gear 144 and the third gear 145, a material transfer block 147 is mounted on the other end of each group of the rotating blocks 146, a plurality of support plates 148 located between the two groups of material transfer blocks 147 are fixedly mounted on the inner bottom end of the soaking box 130, and a material rack 149 is fixedly mounted on the top of each group of the support plates 148.

[0025] When the cleaned metal bars are fully immersed in corrosion protection, the rotation of the first transmission rod 122 prompts the first gear 143 on the inner wall on the other side of the second transmission belt 141 to rotate, causing the second gear 144 and the third gear 145 on both sides of the first gear 143 to rotate synchronously, and then when the second gear 144 and the third gear 145 rotate, the rotating block 146 and the material transfer block 147 located at the other end in the immersion box 130 can rotate, so that the two groups of symmetrically arranged material transfer blocks 147 intermittently transfer the metal bars washed at the rolling plate 125 above the material rack 149, and at the same time prompt the metal bars to be evenly immersed in the immersion box 130, and when the material transfer block 147 rotates back and forth, the metal cleaning agent poured into the immersion box 130 can be evenly turned up to prevent the metal cleaning agent from precipitating inside the immersion box 130 and affecting the immersion corrosion and rust prevention effect of the metal bars.

[0026] Please refer to Figure 7 and Figure 8The cleaning assembly 160 includes a first connecting rod 161 rotatably mounted on the side wall of the second gear 144, the other end of the first connecting rod 161 is rotatably mounted with a second rotating disk 162 fixed with a bearing on the end of the side wall of the cleaning box 150, the other end of the second rotating disk 162 is mounted with a fourth gear 164 that penetrates and extends to the inner wall end of the cleaning box 150 and is fixed with a bearing, the side wall bearing of the cleaning box 150 is mounted with two groups of fifth gears 165 located on both sides of the fourth gear 164, the other ends of the fourth gear 164 and the fifth gear 165 are fixedly mounted with a fourth transmission rod, the outer wall of each group of the fourth transmission rods is sleeved with a conveyor belt 166, the side wall of the second rotating disk 162 is rotatably mounted A second connecting rod 163 is installed, and two groups of second piston cylinders 167 are fixedly installed in the cavity of the cleaning box 150. A top plate 169 extending from the outside of the second piston cylinder 167 and rotatably fixed to the end of the second connecting rod 163 is slidably installed inside each group of second piston cylinders 167. A water tank 168 is fixedly installed at the top center position of the cleaning box 150. Two groups of connecting pipes 1691 fixed to the end of the side wall of the second piston cylinder 167 are fixedly installed on the side wall of the water tank 168. A second water spray pipe 1692 is fixedly installed on the other end of the second piston cylinder 167. A feed plate 1693 fixed to the end of the side wall of the coating box 170 is fixedly installed on the other end of the cleaning box 150.

[0027] When the metal bars after soaking are flushed for the second time, the metal bars after soaking are rolled to the top of the conveyor belt 166. When the third gear 145 rotates, the first connecting rod 161 installed on the side wall is driven to rotate back and forth obliquely, thereby causing the second rotating disk 162 installed on the other end of the first connecting rod 161 to rotate synchronously, driving the fourth gear 164 and the fifth gears 165 on both sides to rotate, thereby rotating the conveyor belt 166, and the rolled metal bars can be evenly rolled into the multiple groups of material troughs installed on the outer wall of the conveyor belt 166, and on the second rotating disk 16 When rotating, the second connecting rod 163 installed on the side wall is driven to rotate and slide back and forth up and down, thereby causing the second push rod installed at the bottom end of the top plate 169 to move back and forth up and down in the second piston cylinder 167. During the up and down movement, the one-way valve in the connecting pipe 1691 is closed and the one-way valve in the second water spraying pipe 1692 is opened, so that the water in the water storage tank 168 is sucked in through the connecting pipe 1691 and sprayed out through the second water spraying pipe 1692, which can perform secondary flushing on the metal cleaning agent and dust remaining on the surface of the metal bar after immersion, further improving the anti-corrosion and anti-rust effect of the metal bar.

[0028] Please refer to Figure 8 and Fig. 9The coating and air-drying component 180 includes a reciprocating screw 183 with bearings installed on both sides of the inner wall of the coating box 170, and the other end of the reciprocating screw 183 is installed with a third transmission rod 182 extending out of the outside of the coating box 170, and the outer wall of the third transmission rod 182 is sleeved with a third transmission belt 181 sleeved with the outer wall of the fourth transmission rod, and the outer wall of the reciprocating screw 183 is sleeved with a spraying mechanism 184, and the upper end of the spraying mechanism 184 is fixedly installed with a tooth plate 185, and the inner wall of the coating box 170 is fixedly installed with a fixed block 186 at a surface contact position with the tooth plate 185, and the inner wall bearing of the fixed block 186 is installed with a positioning rod 187, and the outer wall of the positioning rod 187 is fixedly installed with a fan gear 188, and the other end of the positioning rod 187 is fixedly installed with a fan blade plate 189 located on the outside of the fixed block 186 and above the feed plate 1693.

[0029] When the metal bars after the second rinse are sprayed and quickly dried, when the conveyor belt 166 rotates, the outer wall of the other end is driven to sleeve the third transmission belt 181 to rotate the third transmission rod 182, causing the reciprocating screw 183 to rotate, driving the spraying mechanism 184 to spray the surface of the metal bars after the water absorption treatment at the feed plate 1693. When the spraying mechanism 184 moves, the tooth plate 185 contacts the surface of the fan gear 188, and causes the fan gear 188 to rotate to the left and right sides. When the fan gear 188 rotates, the fan blade plate 189 installed at the other end can fan the metal bars rolling above the feed plate 1693 for air drying, so that the metal bars after the second rinse can be quickly dried to facilitate the subsequent spraying work, and further improve the protection of the metal bar surface.

[0030] Please refer to Figure 1 and Figure 2 A recovery box located below the rolling plate 125 is fixedly mounted on the upper end of the frame 100, a filter screen is slidably mounted on the inner wall of the recovery box, and a return pipe fixed to the end of the water storage tank 1293 is fixedly mounted on the side wall of the recovery box.

[0031] The waste water after flushing can pass through the filter net arranged on the inner wall of the recycling box to block the dust and impurities on the surface of the metal bar and flow into the recycling box. The filtered flushing water can flow into the water storage tank 1293 through the reflux pipe, thus avoiding the waste of water resources.

[0032] Please refer to Figure 2 The upper end of the frame 100 is located above the rolling plate 125 and is fixedly installed with a flushing rack close to the side of the soaking box 130, and the lower end of the flushing rack is fixedly installed with multiple groups of flushing heads connected to the end of the first water spray pipe 1291.

[0033] The flushing head connected to the end of the first water spray pipe 1291 can be used to flush the dust and impurities on the outer wall of the metal rod workpiece rolling above the rolling plate 125, ensuring that no dust and impurities adhere to the surface of the metal rod in the initial stage of immersion anti-corrosion and affect the anti-corrosion immersion treatment of the metal rod.

[0034] Please refer to Figure 2 and Figure 6 The first piston cylinder 127 and the second piston cylinder 167 are both slidably installed with a first push rod 128 extending from the outside of the first piston cylinder 127 and the second piston cylinder 167, and the other end of each group of first push rods 128 is located at the bottom end of the inner wall of the first piston cylinder 127 and the second piston cylinder 167, and a first telescopic spring is fixedly installed thereon, and a one-way valve is provided at the connecting position between the side wall of the first piston cylinder 127 and the end of the first water spray pipe 1291 and the water inlet pipe 1292.

[0035] The one-way valve provided at the connection position between the first water spray pipe 1291 and the water inlet pipe 1292 can control the entry and discharge of water flow inside the first piston cylinder 127 and the second piston cylinder 167, thereby achieving the cleaning work on the surface of the metal bar.

[0036] Please refer to Figure 7 and Figure 8 A plurality of material placing troughs are fixedly mounted on the outer wall of the conveyor belt 166, and the top of the material placing troughs is in a semicircular opening shape.

[0037] The metal bar materials after soaking can evenly fall into the inner part of the multiple groups of material placing troughs installed on the outer wall of the conveyor belt 166, and then be rinsed again.

[0038] Please refer to Figure 7 and Figure 8 A support plate is fixedly installed on the inner wall of the cleaning box 150 and is located on the right side above the conveyor belt 166 and fixed to the end of the second water spray pipe 1692, and multiple groups of water spray heads are fixedly installed below the support plate.

[0039] When the metal rods after soaking pass through the conveyor belt 166, the second water spray pipe 1692 can rinse the metal rods placed above the conveyor belt 166 again through the connected multiple groups of water spray heads to avoid dust adhesion and facilitate subsequent spraying work.

[0040] Please refer to Figure 1 and Figure 2 A plurality of water permeable openings are provided at the upper end of the rolling plate 125 , and a limiting block extending to the inner side of the soaking box 130 is fixedly mounted at the other end of the rolling plate 125 .

[0041] When the metal bars are being cleaned, the flushed water flows into the recovery box through the water permeable port, and the metal bars can roll to the limit block and stop rolling, thereby achieving a uniform feeding effect.

[0042] During use, when cleaning the dust and impurities on the surface of the metal bar, after the metal bar is put into the feed box 121, the motor in the chassis 110 starts to drive the first transmission rod 122 to rotate, causing the feed roller 1294 to evenly feed the metal bar, so that the metal bar evenly falls to the rolling plate 125 and rolls on one side. While the first transmission rod 122 rotates, the first rotating disk 123 rotates synchronously, causing the travel block 126 to reciprocate the first push rods 128 on both sides inside the first piston cylinder 127. When the first push rod 128 moves to the left inside the first piston cylinder 127, the water flow inside the water tank 1293 is driven to circulate through the water inlet pipe 1292 connected at one end until the water flows into the first piston cylinder 127. When the first push rod 128 moves to the right inside the first piston cylinder 127, the first piston cylinder 127 When the internal water flow is replenished, the one-way valve in the water inlet pipe 1292 is closed and the one-way valve in the first water spray pipe 1291 is opened, so that the water flows out through the flushing head connected to one end of the first water spray pipe 1291, and flushes the dust and impurities on the surface of the metal rod rolling on the rolling plate 125, so that the dust and impurities on the surface of the metal rod fall into the recovery box, and the filter net in the recovery box can filter the dust and impurities, and the filtered water flows into the water storage tank 1293 connected to the other end of the recovery box through the return pipe. In this way, dust on the surface of the metal bar is cleaned to prevent adhesion and waste of water resources is avoided. When the cleaned metal bar is fully soaked for corrosion protection, the first transmission rod 122 rotates to cause the first gear 143 on the inner wall of the other side of the second transmission belt 141 to rotate, so that the second gear 144 and the third gear 145 on both sides of the first gear 143 rotate synchronously, and then the second gear 144 and the third gear 145 rotate, which can cause the rotating block 146 and the material delivery block 146 located at the other end in the soaking box 130 to rotate synchronously. The two symmetrically arranged material transfer blocks 147 make a rotational movement, so that the metal bars washed at the rolling plate 125 are intermittently transferred above the material rack 149, and the metal bars are uniformly soaked in the soaking box 130. When the material transfer blocks 147 make a reciprocating rotation, the metal cleaning agent poured into the soaking box 130 can be evenly turned up to prevent the metal cleaning agent from precipitating in the soaking box 130 and affecting the soaking anti-corrosion and anti-rust effect of the metal bars, and the metal bars after soaking can be uniformly soaked in the soaking box 130. During the secondary flushing, the soaked metal bars roll to the top of the conveyor belt 166. When the third gear 145 rotates, the first connecting rod 161 rotatably mounted on the side wall is driven to perform an inclined reciprocating rotation, thereby causing the second rotating disk 162 rotatably mounted on the other end of the first connecting rod 161 to rotate synchronously, driving the fourth gear 164 and the fifth gears 165 on both sides to rotate, thereby rotating the conveyor belt 166, and the rolled metal bars can be evenly rolled into the multiple groups of material troughs installed on the outer wall of the conveyor belt 166.When the second rotating disk 162 rotates, the side wall is driven to rotate and install the second connecting rod 163 to slide back and forth up and down, thereby causing the second push rod installed at the bottom end of the top plate 169 to move back and forth up and down in the second piston cylinder 167. During the up and down movement, the one-way valve in the connecting pipe 1691 is closed and the one-way valve in the second water spray pipe 1692 is opened, causing the water inside the water storage tank 168 to be sucked in through the connecting pipe 1691 and sprayed out through the second water spray pipe 1692, which can perform a secondary flushing of the metal cleaning agent and dust remaining on the surface of the metal rod after immersion, further improving the anti-corrosion and anti-rust effect of the metal rod. When the metal rod after the secondary flushing is sprayed and quickly air-dried, when the conveyor belt 166 rotates, the outer wall of the other end is driven to sleeve the third transmission The belt 181 rotates the third transmission rod 182, causing the reciprocating screw rod 183 to rotate, driving the spraying mechanism 184 to spray the surface of the metal bar after the water absorption treatment at the feed plate 1693. When the spraying mechanism 184 moves, the tooth plate 185 contacts the surface of the fan gear 188, causing the fan gear 188 to rotate to the left and right sides. When the fan gear 188 rotates, the fan blade plate 189 installed at the other end can fan the metal bar rolling above the feed plate 1693 for air drying, which can quickly dry the metal bar after the second rinse to facilitate the subsequent spraying work, and further improve the protection of the metal bar surface. The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology.
