Description

Technical Field

[0001] The invention relates to the technical field of rust-proof liquid treatment, and more specifically to a metal rust-proof cleaning liquid circulation recovery supply device and a working method thereof. Background Art

[0002] Rust-proof liquid is a chemical additive specially used to prevent corrosion and rust on metal surfaces. It can be used on metal surfaces such as steel and aluminum to effectively prevent corrosion of the metal surfaces. Its main ingredients include oily corrosion inhibitors, water-based corrosion inhibitors, rust inhibitors, dehydrating agents, lubricants and penetrants, etc. In addition, rust-proof liquid also has high anti-corrosion properties and adhesion.

[0003] In the prior art, the methods of treating metal surfaces with anti-rust liquid can be roughly divided into three types: spraying, immersion and brushing. The spraying method is suitable for large anti-rust objects or objects that are not easy to immerse, and the anti-rust liquid is evenly sprayed on the metal surface using compressed air and a spray gun. The immersion method is a method suitable for small objects, in which the objects are immersed in the anti-rust liquid to allow a layer of anti-rust grease to adhere to the surface. The brushing method is suitable for outdoor construction equipment or products of special shapes, and the anti-rust liquid is evenly applied to the metal surface using a brush.

[0004] However, when faced with metal workpieces of different sizes and specifications, manufacturers in the current market often adopt the strategy of purchasing and configuring corresponding anti-rust liquid recovery and supply devices according to the specific size of the workpiece, so that different anti-rust liquid recovery and supply devices can only recover the anti-rust liquid on the surface of a specific workpiece. This practice undoubtedly increases the manufacturer's initial investment cost, and also increases the difficulty of equipment maintenance and management.

[0005] At the same time, in the process of machining large metal workpieces, grinding fluid is generally used for spray cooling while machining is in progress. After machining is completed, anti-rust treatment is usually performed immediately by spraying. This is to prevent the workpiece surface from contacting with oxygen in the air and causing oxidation reaction, thereby affecting the corrosion resistance and surface quality of the workpiece. However, in this process, the grinding fluid on the workpiece surface is not recovered in time, which may cause the grinding fluid and the rust-proof liquid to mix, resulting in the mixed liquid may not meet the rust-proof standard of the original rust-proof liquid, thereby reducing the rust-proof effect and affecting the rust-proof performance of the rust-proof liquid.

[0006] After the anti-rust liquid is sprayed on the surface of the workpiece, the heat generated by the workpiece processing will directly affect the temperature of the anti-rust liquid, thereby affecting the optimal anti-rust temperature of the anti-rust liquid and further reducing the anti-rust performance of the anti-rust liquid. For this reason, a metal anti-rust cleaning liquid recycling supply device and a working method thereof are proposed to improve the existing problems. Summary of the invention

[0017] The method for recycling and supplying a metal anti-rust cleaning liquid uses the metal anti-rust cleaning liquid recycling and supplying device as described above, comprising the following steps:

[0018] S1. When the large metal workpiece is processed and sprayed with grinding fluid at the same time, the driving motor is started, and its output end drives the threaded rod to rotate, so that the driving block makes a horizontal linear displacement, thereby driving the driving plate and the wiping member to move synchronously. In this process, the wiping member is started, which can limit the outer surface of the large metal workpiece on the one hand, and wipe and clean the grinding fluid and debris on the outer surface of the large metal workpiece on the other hand; at this time, the adjusting member is in a state of separating the space in the recovery bin, so the grinding fluid and debris will flow out of the recovery bin;

[0019] S2. Next, after the anti-rust liquid is sprayed on the surface of the large metal workpiece, the anti-rust liquid will flow from the surface of the large metal workpiece into the recovery bin. At this time, the adjustment part is started to make the space in the recovery bin interconnected, and the anti-rust liquid will continue to flow into the conveying cylinder through the adjustment part;

[0020] S3. Subsequently, the conveying motor is started, and its output end drives the main transmission wheel to rotate, so that the secondary transmission wheel rotates synchronously through the transmission belt, so that the secondary shaft drives the secondary gear to rotate, and the main shaft rotates synchronously through the meshing transmission of the main gear and the secondary gear, so that the two main shafts drive the spiral blades to rotate synchronously, so that the anti-rust liquid can continue to be horizontally conveyed through the rotation of the spiral blades;

[0021] S4. During this process, the staff can transport the cooling medium in the temperature control pipe and spray the outer wall of the conveying cylinder through the nozzle, so that the anti-rust liquid in the conveying cylinder gradually reaches the optimal anti-rust temperature; at the same time, the telescopic cylinder is started, and its telescopic end extends or retracts, thereby driving the telescopic strip, the temperature control pipe and the nozzle to move synchronously;

[0022] S5. Before rust-proofing small metal workpieces, several small metal workpieces can be placed on the screen plate first. On the one hand, the first telescopic rod is started, and its telescopic end is retracted, driving the limit plate to approach the small metal workpiece and squeeze and clamp the small metal workpiece; on the other hand, the reciprocating motor is started, and its output end drives the rotating shaft and the rotating plate to rotate, thereby driving the reciprocating plate to move back and forth, so that the screen plate and the small metal workpieces reciprocate synchronously; in this process, the electric slider will drive the slide plate, the first telescopic rod and the limit plate to slide back and forth synchronously on the slide rail.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] (1) The first recovery unit is designed to effectively and independently collect and process the grinding fluid and rust-proof fluid used in the machining of large metal workpieces; this design ensures that the two fluids do not mix during the recovery process, thereby avoiding chemical reactions or physical changes that may negatively affect the rust-proof performance.

[0025] (2) By conveying the cooling medium in the temperature-controlled pipe and spraying the outer wall of the conveying tube through the nozzle, the rust-proof liquid in the conveying tube gradually reaches the optimal rust-proof temperature, so that the temperature of the rust-proof liquid passing through the surface of the large metal workpiece can be controlled to ensure that the rust-proof liquid can still be maintained in an ideal and optimal rust-proof temperature range after the first use or after repeated use, so as to maximize its rust-proof performance; this can not only extend the service life of the rust-proof liquid and reduce costs, but also improve the rust-proof quality of the workpiece, ensuring that the performance or appearance of the workpiece will not be reduced due to rust during storage or transportation.

[0026] (3) On the one hand, the first telescopic rod drives the limit plate to approach the small metal workpiece and clamp and squeeze the small metal workpiece; on the other hand, the reciprocating motor is started to drive the rotating shaft and the rotating plate to rotate, thereby driving the reciprocating plate to move back and forth, so that the screen plate and the small metal workpieces can reciprocate synchronously, and the moisture of multiple small metal workpieces can be quickly and thoroughly removed, thereby avoiding the problem of small and medium-sized metal workpieces in the prior art that the concentration of the anti-rust liquid is reduced due to multiple rinses with clean water and then soaking in the anti-rust liquid, thereby ensuring the concentration of the anti-rust liquid and further improving the anti-rust effect of the anti-rust liquid.

[0039] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0040] See also Figure 1-Figure 9 , the present invention provides the following technical solutions:

[0041] Example 1, see Figure 1-Figure 9, a metal anti-rust cleaning liquid circulation recovery supply device comprises a first recovery unit 1, a temperature control unit 2 and a second recovery unit 3; wherein, the first recovery unit 1 is used to effectively and independently collect and process the grinding fluid and the anti-rust liquid used in the processing of large metal workpieces; this design ensures that the two liquids will not mix during the recovery process, thereby avoiding chemical reactions or physical changes that may have a negative impact on the anti-rust performance.

[0042] The function of the temperature control unit 2 is to control the temperature of the rust-proof liquid passing through the surface of the large metal workpiece, ensuring that the rust-proof liquid can still be maintained in an ideal and optimal rust-proof temperature range after the first use or after repeated use, so as to maximize its rust-proof performance; this can not only extend the service life of the rust-proof liquid and reduce costs, but also improve the rust-proof quality of the workpiece, ensuring that the performance or appearance of the workpiece will not be reduced due to rust during storage or transportation.

[0043] In addition, the use of the temperature control unit 2 also helps to improve production efficiency and product quality; since it can stabilize the temperature of the anti-rust liquid, it can reduce production interruptions or rework caused by temperature fluctuations on the production line, thereby ensuring the continuity and stability of production; at the same time, by maintaining the optimal performance of the anti-rust liquid, it can also improve the quality of the final product and enhance its market competitiveness.

[0044] The function of the second recovery unit 3 is to quickly and thoroughly remove moisture from multiple small metal workpieces at the same time through specific mechanical movement or vibration, thereby avoiding the problem in the prior art that the concentration of the rust-proof liquid is reduced due to the small and medium-sized metal workpieces being rinsed with clean water for many times and then immersed in the rust-proof liquid, thereby ensuring the concentration of the rust-proof liquid and further improving the rust-proof effect of the rust-proof liquid.

[0045] Through the coordinated work of the first recycling unit 1 and the second recycling unit 3, the manufacturer can flexibly deal with metal workpieces of various sizes and specifications, and realize the precise recovery and treatment of anti-rust liquid on the surfaces of different workpieces; this cooperation not only improves the adaptability and flexibility of the recycling device, but also significantly enhances the efficiency and effectiveness of the entire production process.

[0046] See also Figure 1-Figure 6Specifically, the first recycling unit 1 includes a support frame 11, a conveying motor 12 arranged in the support frame 11, a main transmission wheel 121 arranged at the output end of the conveying motor 12, a secondary transmission wheel 122 arranged above the main transmission wheel 121, a transmission belt 123 sleeved on the main transmission wheel 121 and the secondary transmission wheel 122, a secondary shaft 124 arranged at one end of the secondary transmission wheel 122, a secondary gear 125 arranged on the secondary shaft 124, a main gear 126 meshing with the secondary gear 125 for transmission, and a main shaft arranged at one end of the main gear 126. 127, spiral blades 128 symmetrically arranged on the secondary shaft 124 and the main shaft 127 in the axial M direction, a conveying cylinder 129 sleeved on the spiral blades 128, a recovery bin 13 arranged above the conveying cylinder 129, a driving motor 14 arranged on the side wall of the recovery bin 13, a threaded rod 15 arranged at the output end of the driving motor 14, a driving block 16 arranged on the threaded rod 15, a driving plate 17 arranged on the top of the driving block 16, a wiping member 18 arranged on the top of the driving plate 17, and an adjusting member 19 arranged in the recovery bin 13.

[0047] Among them, when the large metal workpiece is processed and sprayed with grinding fluid at the same time, the driving motor 14 is started, and its output end drives the threaded rod 15 to rotate, so that the driving block 16 makes a horizontal linear displacement, thereby driving the driving plate 17 and the wiping member 18 to move synchronously. In this process, the wiping member 18 is started. On the one hand, it can limit the outer surface of the large metal workpiece, and on the other hand, it can also wipe and clean the grinding fluid and metal debris on the outer surface of the large metal workpiece, preventing these residues from mixing with the anti-rust liquid in the subsequent anti-rust treatment process, thereby ensuring the purity of the anti-rust liquid and the anti-rust effect; at this time, the adjusting member 19 is not started, and the bottom of the recovery bin 13 can be blocked, so that the grinding fluid and debris can only flow out through the side of the recovery bin 13.

[0048] Next, the rust-proof liquid that has passed through the surface of the large metal workpiece will flow from the surface of the large metal workpiece into the recovery bin 13. At this time, the adjustment member 19 is started to open the bottom of the recovery bin 13, so that the space of the recovery bin 13 and the conveying cylinder 129 are interconnected, and the rust-proof liquid will continue to flow into the conveying cylinder 129 through the recovery bin 13; this independent collection and circulation supply mechanism can effectively avoid the mixing of the grinding fluid and the rust-proof liquid, ensuring that the rust-proof liquid always maintains its original rust-proof standard and performance; this not only improves the rust-proof effect of the workpiece and extends its service life, but also reduces the maintenance cost and potential safety hazards caused by rust.

[0049] Subsequently, the conveying motor 12 is started, and its output end drives the main transmission wheel 121 to rotate, so that the secondary transmission wheel 122 rotates synchronously through the transmission belt 123, so that the secondary shaft 124 drives the secondary gear 125 to rotate, and the main shaft 127 rotates synchronously through the meshing transmission of the main gear 126 and the secondary gear 125, so that the secondary shaft 124 and the main shaft 127 drive the corresponding spiral blades 128 to rotate synchronously, so that the rust-proof liquid can continue to be horizontally conveyed through the rotation of the spiral blades 128.

[0050] See also Figure 7 Specifically, the temperature control unit 2 is arranged at one end of the recovery bin 13, and includes a temperature control cover 21, a fixed plate 22 symmetrically arranged in the temperature control cover 21 in the axial M direction, a telescopic cylinder 23 arranged at the bottom of the fixed plate 22, a telescopic bar 24 arranged at the telescopic end of the telescopic cylinder 23, a temperature control pipe 25 evenly arranged between the telescopic bars 24, and a nozzle 26 evenly arranged on the outer wall of the temperature control pipe 25.

[0051] Among them, the staff can transport the cooling medium in the temperature control pipe 25, and spray the outer wall of the conveying cylinder 129 through the nozzle 26, so that the rust-proof liquid in the conveying cylinder 129 gradually reaches the optimal rust-proof temperature, so that the rust-proof liquid passing through the surface of the large metal workpiece can be temperature-controlled to ensure that the rust-proof liquid can still be maintained in an ideal and optimal rust-proof temperature range after the first use or after repeated use, so as to maximize its rust-proof performance; this can not only extend the service life of the rust-proof liquid and reduce costs, but also improve the rust-proof quality of the workpiece, ensuring that the performance or appearance of the workpiece will not be reduced due to rust during storage or transportation.

[0052] At the same time, the telescopic cylinder 23 is started, and its telescopic end is extended or retracted, thereby driving the telescopic strip 24, the temperature control pipe 25 and the nozzle 26 to move synchronously, thereby increasing the spraying range.

[0053] See also Figure 8-Figure 9Specifically, the second recovery unit 3 is arranged at one end of the support frame 11, and includes an extension frame 31, a soaking box 32 arranged on the top of the extension frame 31, a reciprocating motor 33 arranged at one end of the soaking box 32, a rotating shaft 331 arranged at the output end of the reciprocating motor 33, a rotating plate 332 arranged at the end of the rotating shaft 331 away from the reciprocating motor 33, a reciprocating plate 333 rotatably connected to the end of the rotating plate 332 away from the rotating shaft 331, a sieve plate 334 rotatably connected to the end of the reciprocating plate 333 away from the rotating plate 332, a horizontal plate 34 symmetrically arranged on both sides of the soaking box 32 in the axial M direction, a slide rail 35 arranged on the top of the horizontal plate 34, an electric slider 351 sliding on the slide rail 35, a slide plate 36 arranged on the top of the electric slider 351, a first telescopic rod 37 arranged at the top of the slide plate 36, a limit plate 38 arranged between the first telescopic rods 37, and an opening and closing member 39 arranged at the end of the soaking box 32 away from the reciprocating motor 33.

[0054] Among them, before rust prevention of small metal workpieces, several small metal workpieces can be placed on the sieve plate 334 first, and then, on the one hand, the first telescopic rod 37 is started, and its telescopic end is retracted, driving the limit plate 38 to approach the small metal workpiece, and clamping and squeezing the small metal workpiece; on the other hand, the reciprocating motor 33 is started, and its output end drives the rotating shaft 331 and the rotating plate 332 to rotate, thereby driving the reciprocating plate 333 to move back and forth, so that the sieve plate 334 and the small metal workpieces reciprocate synchronously, and the moisture of multiple small metal workpieces is quickly and thoroughly removed, thereby avoiding the problem of reduced concentration of rust-proof liquid due to repeated rinsing of small and medium-sized metal workpieces in the prior art and then soaking in rust-proof liquid, thereby ensuring the concentration of the rust-proof liquid and further improving the rust-proof effect of the rust-proof liquid.

[0055] During this process, the electric slider 351 drives the slide plate 36 , the first telescopic rod 37 and the limit plate 38 to slide back and forth synchronously on the slide rail 35 .

Both ends of the main shaft 127 can pass through the corresponding side walls of the support box 111 through bearings; a support plate 112 is also provided on the top of the support frame 11, one end of the conveying cylinder 129 can be connected to the side wall of the support box 111, and the other end can pass through the side wall of the support plate 112, and the two conveying cylinders 129 are connected; a conveying groove 1291 is also provided on the top of the connection between the conveying cylinders 129, and the bottom of the recovery bin 13 can be connected to the two conveying cylinders 129 through the conveying groove 1291.

[0057] Among them, when re-supplying rust removal liquid to large metal workpieces, the staff can use a water pump to re-extract and supply the anti-rust liquid delivered to the conveying cylinder 129 and the penetration point of the support plate 112, thereby achieving the purpose of circulating supply; the anti-rust liquid will continue to flow into the conveying cylinder 129 through the recovery bin 13 and the conveying trough 1291.

[0058] See also Figure 1-6 Furthermore, both ends of the threaded rod 15 can be rotatably connected to the corresponding side walls of the recovery bin 13; the wiping member 18 includes a clamping cylinder 181, a clamping plate 182 symmetrically arranged at the output end of the clamping cylinder 181 in the axial M direction, and a sponge 183 arranged on the side wall of the clamping plate 182; the sponges 183 are relatively distributed.

[0059] Among them, the clamping cylinder 181 is started, and its telescopic end pulls the two clamping plates 182 closer to each other. On the one hand, it can limit the outer surface of the large metal workpiece, and on the other hand, the grinding fluid and metal debris on the outer surface of the large metal workpiece can be wiped and cleaned by the sponge 183, preventing these residues from mixing with the anti-rust liquid in the subsequent anti-rust treatment process, thereby ensuring the purity of the anti-rust liquid and the anti-rust effect.

[0065] When collecting the anti-rust liquid on the surface of the large metal workpiece, on the one hand, the adjusting cylinder 192 is started, and its telescopic end is extended to push the adjusting rod 193, so that the two first adjusting plates 194 respectively rotate around the corresponding connecting column 1913, thereby pushing the partition cover 195 to flip around the second adjusting plate 196, and making the partition cover 195 away from the partition plate 191, exposing the through groove 1911, and the anti-rust liquid on the surface of the large metal workpiece can flow to the conveying cylinder 129 through the through groove 1911.

[0066] On the other hand, the flipping cylinder 133 is started, pulling the limit bar 132 to flip around the hinge in the drainage groove 131, so that the limit bar 132 blocks the drainage groove 131, and the side wall where the limit bar 132 contacts and fits the partition plate 191 is away from the excess side wall of the partition plate 191, so that there is a gap between the excess side wall of the partition plate 191 and the recovery bin 13; through the design of the ring plate 1912 and the ring groove 1951, when the anti-rust liquid drops onto the partition plate 191, it can flow along the side wall of the partition plate 191 through the gap between the excess side wall of the partition plate 191 and the recovery bin 13 to the conveying cylinder 129.

[0068] Among them, the telescopic cylinder 23 is started, and its telescopic end is extended or retracted, so that the pulley 222 can be driven to slide in the fixed groove 221 through the telescopic bar 24 and the connecting plate 223, and the temperature control pipe 25 and the nozzle 26 are displaced synchronously, thereby increasing the spraying range.

[0069] Embodiment 3, through the cooperation of embodiment 1 and embodiment 2, although the problem in the prior art that the grinding fluid on the surface of the workpiece is not recovered in time, resulting in the mixed liquid may not meet the rust prevention standard of the original rust prevention liquid, and the heat of workpiece processing directly affects the temperature of the rust prevention liquid, so that the optimal rust prevention temperature of the rust prevention liquid is affected, it still does not solve the problem in the prior art that the concentration of the rust prevention liquid is reduced due to the small and medium-sized metal workpieces being rinsed with clean water for many times and then immersed in the rust prevention liquid; for this purpose, the following solution is proposed:

[0070] See also Figure 8-Figure 9 Furthermore, the top of the immersion box 32 is open and the bottom is closed. A cutout 321 is provided at one end of the immersion box 32.

[0071] When the rust removal is not performed by immersion, the liquid level of the rust removal liquid in the immersion box 32 is not higher than the cutout 321 ; when the sieve plate 334 and the small metal workpiece are immersed at the same time, the liquid level of the rust removal liquid is also not higher than the height of the cutout 321 .

[0072] When the sieve plate 334 and the small metal workpieces are synchronously reciprocating, the sieve plate 334 will slide on the sliding roller 323 along the length direction of the immersion box 32, causing the sliding roller 323 to roll; and through the design of the second telescopic rod 322, when the small metal workpieces on the sieve plate 334 are free of moisture, the telescopic end of the second telescopic rod 322 will retract, thereby driving the sieve plate 334 and the small metal workpieces to descend at the same time and be immersed in the rust removal liquid.

[0073] See also Figure 8-Figure 9 Furthermore, auxiliary grooves 324 are symmetrically provided on both side walls of the immersion box 32, and an auxiliary plate 325 is provided in the immersion box 32.

[0074] Among them, through the design of the auxiliary groove 324, the auxiliary plate 325 and the handle 326, the staff can push the handle 326 and the auxiliary plate 325 so that the two ends of the auxiliary plate 325 are inserted into the corresponding auxiliary groove 324, thereby achieving the purpose of dividing the space in the immersion box 32; therefore, the small metal workpiece is located in one of the spaces in the immersion box 32 for dewatering, and the dripping water will be discharged through the diversion valve of the immersion box 32.

[0075] See also Figure 8-Figure 9Furthermore, the opening and closing member 39 includes a push handle 391, a flow limiting plate 392 arranged below the push handle 391, and a height limiting plate 393 arranged at both ends of the flow limiting plate 392; the two ends of the push handle 391 can be connected to the side walls of one of the height limiting plates 393; a transition groove 327 is also provided on the side wall of the end of the immersion box 32 away from the reciprocating motor 33, a transition channel 328 is provided at one end of the transition groove 327, and a one-way valve 3281 is provided in the transition channel 328; a flow limiting groove 329 is also provided on the top of the end of the immersion box 32 away from the reciprocating motor 33, the flow limiting plate 392 can be cooperated and plugged into the flow limiting groove 329, and a square hole is provided in the middle of the flow limiting plate 392.

[0076] Among them, when the first recovery unit 1 and the second recovery unit 3 need to be used in combination, the support plate 112 and the immersion box 32 can be fixed by bolts at one end away from the reciprocating motor 33, thereby achieving the purpose of combined use; then, the limiting plate 392 is pushed by the push handle 391, so that the limiting plate 392 is displaced in the limiting groove 329, so that the square hole in the middle of the limiting plate 392 is aligned with the transition groove 327, so that the rust removal liquid can pass through the square hole in the middle of the limiting plate 392, the transition groove 327 and the transition channel 328 into another space of the immersion box 32 for storage; in this process, through the design of the one-way valve 3281, the rust removal liquid cannot flow back into the conveying cylinder 129.

[0077] When it is necessary to soak a small metal workpiece, the handle 326 and the auxiliary plate 325 are pulled to make the separated spaces in the soaking box 32 communicate with each other again. At this time, the guide valve of the soaking box 32 is in a closed state.

In this process, the wiping member 18 is started, which can limit the outer surface of the large metal workpiece on the one hand, and wipe and clean the grinding fluid and debris on the outer surface of the large metal workpiece on the other hand; at this time, the adjusting member 19 is in a state of separating the space in the recovery bin 13, so the grinding fluid and debris will flow out of the recovery bin 13;

[0080] S2. Next, after the anti-rust liquid is sprayed on the surface of the large metal workpiece, the anti-rust liquid will flow from the surface of the large metal workpiece into the recovery bin 13. At this time, the adjustment member 19 is started, so that the space in the recovery bin 13 is interconnected, and the anti-rust liquid will continue to flow into the conveying cylinder 129 through the adjustment member 19.

Subsequently, the conveying motor 12 is started, and its output end drives the main transmission wheel 121 to rotate, so that the secondary transmission wheel 122 rotates synchronously through the transmission belt 123, so that the secondary shaft 124 drives the secondary gear 125 to rotate, and the main shaft 127 rotates synchronously through the meshing transmission of the main gear 126 and the secondary gear 125, so that the two main shafts 127 drive the spiral blades 128 to rotate synchronously, so that the rust-proof liquid can continue to be horizontally conveyed through the rotation of the spiral blades 128;

[0082] S4. During this process, the staff can transport the cooling medium in the temperature control pipe 25 and spray the outer wall of the conveying cylinder 129 through the nozzle 26, so that the anti-rust liquid in the conveying cylinder 129 gradually reaches the optimal anti-rust temperature; at the same time, the telescopic cylinder 23 is started, and its telescopic end is extended or retracted, thereby driving the telescopic bar 24, the temperature control pipe 25 and the nozzle 26 to move synchronously;

[0083] S5. Before rust prevention of small metal workpieces, several small metal workpieces can be placed on the screen plate 334. On the one hand, the first telescopic rod 37 is started, and its telescopic end is retracted, driving the limit plate 38 to approach the small metal workpiece and squeeze and clamp the small metal workpiece; on the other hand, the reciprocating motor 33 is started, and its output end drives the rotating shaft 331 and the rotating plate 332 to rotate, thereby driving the reciprocating plate 333 to move back and forth, so that the screen plate 334 reciprocates with the small metal workpiece synchronously; in this process, the electric slider 351 will drive the slide plate 36, the first telescopic rod 37 and the limit plate 38 to slide back and forth synchronously on the slide rail 35.

When the large metal workpiece is processed and sprayed with grinding fluid at the same time, the drive motor (14) is started, and its output end drives the threaded rod (15) to rotate, so that the drive block (16) moves horizontally and linearly, thereby driving the drive plate (17) and the wiping member (18) to move synchronously. During this process, the wiping member (18) is started, and on the one hand, the outer surface of the large metal workpiece is limited, and on the other hand, the grinding fluid and metal debris on the outer surface of the large metal workpiece are wiped and cleaned; at this time, the regulating member (19) is not started, and the bottom of the recovery bin (13) is blocked, so that the grinding fluid and debris can only flow out through the side of the recovery bin (13); S2. Next, the anti-rust cleaning liquid that has passed through the surface of the large metal workpiece will flow from the surface of the large metal workpiece into the recovery bin (13).

During this process, the staff transports the cooling medium in the temperature control pipe (25) and sprays the outer wall of the conveying cylinder (129) through the nozzle (26), so that the anti-rust cleaning liquid in the conveying cylinder (129) gradually reaches the optimal anti-rust temperature; at the same time, the telescopic cylinder (23) is started, and its telescopic end is extended or retracted, thereby driving the telescopic bar (24), the temperature control pipe (25) and the nozzle (26) to move synchronously; S5.

On the one hand, the first telescopic rod (37) is started, and its telescopic end is retracted, driving the limit plate (38) to approach the small metal workpieces and squeeze and clamp the small metal workpieces. On the other hand, the reciprocating motor (33) is started, and its output end drives the rotating shaft (331) and the rotating plate (332) to rotate, thereby driving the reciprocating plate (333) to move back and forth, so that the sieve plate (334) and the small metal workpieces move back and forth synchronously.
