Description

Technical Field

[0001] This invention relates to the field of steel processing equipment technology, specifically to an integrated automatic steel cutting equipment and process method that integrates pickling pretreatment. Background Technology

[0002] The integrated automatic steel cutting equipment with pickling pretreatment is an intelligent device that combines the two processes of steel pickling and automatic cutting into one. It can continuously complete a series of processes such as rust removal, cleaning, drying and cutting, saving time and labor and increasing efficiency. The integrated automatic steel cutting equipment with pickling pretreatment uses multiple spray systems set above the conveyor belt. The front spray system sprays pickling liquid, and the rear spray system sprays cleaning liquid. The steel first passes through the pickling liquid spray system to be pickled by the pickling liquid, and then passes through the cleaning liquid spray system. The cleaning liquid can wash away the pickling liquid residue on the steel, thereby avoiding the impact of pickling liquid residue on the cutting effect during laser cutting.

[0003] After the pickling solution is washed off the steel, in order to avoid the water affecting the laser cutting, the water on the steel needs to be wiped dry before cutting. The existing integrated automatic steel cutting equipment with integrated pickling pretreatment uses a water-absorbing sponge roller on the transmission component. When the steel passes through the water-absorbing sponge roller, the water on its surface is absorbed by the sponge, thereby achieving the purpose of removing the residual water on the steel surface.

[0004] Existing devices use absorbent sponge rollers to absorb moisture from the surface of steel, effectively treating residual moisture. These rollers offer advantages such as good absorption, rapid absorption, and high efficiency. However, addressing the issue of reduced absorption capacity after the sponge becomes saturated remains a challenge. The process of regularly removing and replacing the absorbent sponge rollers requires downtime, which delays the work progress and increases labor costs.

[0005] By installing scrapers and drainage components on the absorbent sponge roller, the sponge is squeezed by the scrapers during rotation, and the squeezed water is drained away through the drainage components. This method effectively solves the problem of the sponge's absorption capacity decreasing after it becomes saturated with water. However, in actual use, the sponge needs to be continuously or frequently subjected to the squeezing action of the scrapers and then return to its original shape after being squeezed. This repeated squeezing and restoring cycle may cause the sponge material to gradually lose its elastic memory, thus weakening its deformation ability. Over time, this will negatively impact the overall performance and service life of the sponge roller.

[0006] To address the aforementioned issues, there is an urgent need for innovative designs based on existing integrated automatic steel cutting equipment and processes that incorporate pickling pretreatment. Summary of the Invention

[0007] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide an integrated automatic steel cutting equipment and process method that incorporates pickling pretreatment, thereby solving the problem mentioned in the background technology where sponge rollers gradually lose their elastic memory due to continuous squeezing and resetting by scrapers, resulting in weakened deformation capacity and consequently affecting their performance and service life.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an integrated automatic steel cutting equipment with pickling pretreatment, comprising a conveyor frame, a pickling spray mechanism and a cleaning spray mechanism mounted on the conveyor frame, and a laser cutting machine, and further comprising: Sponge rollers symmetrically positioned between the cleaning spray mechanism and the laser cutting machine to absorb moisture from the surface of the steel. A rotating tube on the sponge roller adaptively locks in moisture based on the sponge's water absorption state, and a water-absorbing tube fixed at equal angles to the inner wall of the rotating tube for absorbing moisture from the sponge. A suction component installed inside the suction pipe to absorb water from the sponge roller; A drive component located at one end of the suction pipe to drive the suction component to draw water; The suction component includes a sealing plug disposed inside the suction tube for intermittent water suction; The driving component includes driving columns that are evenly distributed inside the water suction pipe to drive the sealing plug to reciprocate.

[0009] Preferably, the rotating tube is rotatably connected to the conveyor frame; The bottom of the conveyor frame is equipped with a drainage trough.

[0010] Preferably, a water-locking pipe is uniformly fixedly installed on the outer wall of the water suction pipe; The inner wall of the water-locking pipe is equipped with an inlet one-way valve; One end of the suction pipe is equipped with an outflow check valve.

[0011] Preferably, a water storage tray is fixedly connected to one end of the rotating tube; The outer wall of the water storage pan is provided with a water outlet pipe; One end of the water suction pipe extends into the interior of the water storage pan.

[0012] Preferably, the suction component further includes a first spring fixed to the inner wall of the suction tube; One end of the first spring is fixedly connected to the sealing plug; The outer wall of the sealing plug is slidably connected to the inner wall of the water suction pipe; A pull rope is fixedly connected to one side of the sealing plug.

[0013] Preferably, the inner wall of the water suction pipe is provided with a through groove; The pull rope is slidably connected to the through groove.

[0014] Preferably, the driving component further includes a rotating roller fixed to one end of the rotating tube; The drive column is slidably sleeved with the rotating roller; The inner wall of the rotating roller is fixedly installed with a second spring at equal angles; A mounting plate is fixedly connected to one end of the second spring; The mounting plate is fixedly connected to the drive column.

[0015] Preferably, the rotating roller has a circular annular structure; The end of the drive column has an arc-shaped structure.

[0016] Preferably, one end of the pull rope is fixedly connected to one side of the drive column.

[0017] An automated cutting process for steel with integrated pickling pretreatment includes the following steps: S1: The steel first passes through the pickling spraying mechanism to be pickled by the pickling solution, and then passes through the cleaning spraying mechanism to be cleaned by the cleaning solution to remove the residual pickling solution. Before passing through the laser cutting machine, it passes through two sponge rollers. The sponge rollers can absorb the moisture on the surface of the steel. The sponge rollers have good deformation force and can adhere more fully to the surface of the steel when absorbing water. They can also absorb the moisture accumulated in the small pits on the surface of the steel. S2: When the two sponge rollers rotate relative to each other, they drive the two rotating rollers to rotate relative to each other. When the two rotating rollers rotate relative to each other, the two driving columns opposite each other will be squeezed. One end of the driving column will pull the sealing plug through the pull rope, so that the water suction pipe can absorb the water on the sponge rollers. S3: When the two mutually pressing drive columns rotate to disengage from each other, the two drive columns are reset by the second spring, the pull rope is no longer pulled, so the sealing plug can be reset by the first spring, and the pressure inside the suction pipe will push the water to the outgoing one-way valve, and the water enters the interior of the water storage pan through the outgoing one-way valve.

[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. Steel is conveyed via a conveyor frame and first undergoes pickling by an acid-pickled spraying mechanism, followed by cleaning by a cleaning spraying mechanism to remove residual acid. Before entering the laser cutting machine, the steel passes through two honeycomb-shaped sponge rollers. These rollers adhere to the steel surface, absorbing moisture effectively, even in areas with rust or pits. A motor on the conveyor frame drives a rotating tube, causing the sponge rollers to rotate relative to each other. The drive columns on the rotating rollers press against each other during relative rotation, causing them to slide into the rotating tube, stretching the second spring and pulling the sealing plug via a rope, creating negative pressure in the suction pipe. The suction pipe then draws moisture from the sponge rollers through a locking pipe, which simultaneously exerts additional suction on the steel, enhancing the absorption effect. When the drive columns disengage, the second spring resets, and the sealing plug returns to its original position via the first spring. The water in the suction pipe is then discharged into a storage pan via a one-way valve. This process eliminates the need for scraper-based pressure on the sponge rollers, offering advantages such as superior absorption, higher drainage efficiency, and longer service life compared to existing technologies.

[0019] 2. In addition, during the continuous operation of the sponge roller, the rotating tube is driven by the motor to rotate continuously. The drive columns distributed at equal angles will be squeezed against each other one by one. The drive columns that are squeezed against each other are the two drive columns that have rotated to the bottom and top. Therefore, only the water-locking tube close to the steel surface will generate suction, thereby achieving precise water absorption and further improving the water absorption effect. Compared with the existing technology, it has the advantages of more precise water absorption and higher efficiency. Attached Figure Description

Detailed Implementation

[0032] 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.

[0033] Please see Figures 1 to 11 This invention provides a technical solution: an integrated automatic steel cutting device with pickling pretreatment, comprising a conveyor frame 1, a pickling spray mechanism 6, a cleaning spray mechanism 7, and a laser cutting machine 3 mounted on the conveyor frame 1, and further comprising: Sponge rollers 2 are symmetrically arranged between the cleaning spray mechanism 7 and the laser cutting machine 3 to absorb moisture from the surface of the steel. A rotating tube 21 is installed on the sponge roller 2 to adaptively lock in moisture based on the sponge's water absorption state, and a water-absorbing tube 26 is fixed at equal angles to the inner wall of the rotating tube 21 to absorb moisture from the sponge. A suction component installed inside the suction pipe 26 to absorb water from the sponge roller 2; A driving component located at one end of the suction pipe 26 for driving the suction component to draw water; The suction component includes a sealing plug 24 disposed inside the suction pipe 26 for intermittent water suction; The driving component includes drive columns 41 that are equidistantly distributed inside the suction pipe 26 for driving the reciprocating movement of the sealing plug 24.

[0034] In specific implementation, the appendix Figure 1 To be continued Figure 3As shown, the pickling spray mechanism 6, the cleaning spray mechanism 7, and the laser cutting machine 3 are all existing devices and will not be explained in detail here. The steel is conveyed by the conveyor frame 1 and sequentially passes through the pickling spray mechanism 6, the cleaning spray mechanism 7, the sponge rollers 2, and the laser cutting machine 3. The pickling spray mechanism 6 sprays pickling liquid, and the cleaning spray mechanism 7 sprays cleaning liquid. The steel first passes through the pickling spray mechanism 6 to be pickled by the pickling liquid, and then passes through the cleaning spray mechanism 7. The cleaning liquid can remove residual pickling liquid from the steel, thus preventing residual pickling liquid from affecting the cutting effect during laser cutting. Before passing through the laser cutting machine 3, it passes through two sponge rollers 2, which are attached... Figure 1 To be continued Figure 5 As shown, two sponge rollers 2 are arranged vertically, with the gap between them slightly smaller than the thickness of the steel. When the steel passes over the two sponge rollers 2, the rollers are subjected to a certain degree of compression. Therefore, the sponge rollers 2 can absorb moisture from the steel surface. Furthermore, the outer wall of the sponge rollers 2 is honeycomb-shaped, providing good deformation force. When absorbing water from the steel plate, the sponge rollers 2 deform under the pressure, allowing them to adhere more comprehensively to the steel surface. When the steel surface has small pits caused by rust corrosion, the sponge rollers 2 can also fill these pits due to deformation. The device absorbs the water accumulated in the small pits, and motors are symmetrically arranged on the conveyor frame 1. The rotating shafts of the two motors can be installed together with the rotating tubes 21 on the two sponge rollers 2. The two motors can drive the rotating tubes 21 to rotate relative to each other, thereby causing the two sponge rollers 2 to rotate relative to each other. The two sponge rollers 2 will not affect the conveying of steel during the water absorption process. It should be noted that the two motors that drive the sponge rollers 2 to rotate are already mature technologies in the prior art. In this device, they are only used as power sources to drive the two sponge rollers 2 to rotate relative to each other, and are not shown in the figure.

[0035] Rotary tube 21 is rotatably connected to conveyor frame 1; A drainage trough is provided at the bottom of the conveyor frame 1.

[0036] In specific implementation, such as Figures 1-3 As shown, there are two drainage tanks, which are located below the pickling spray mechanism 6 and the cleaning spray mechanism 7, respectively. The outlets of the two drainage tanks can be connected to two external drainage pipes or other drainage devices. The pickling solution and the cleaning solution enter different drainage tanks, so the pickling solution and the cleaning solution can be collected separately, which facilitates the subsequent treatment of waste liquid.

[0037] Water-locking pipes 22 are evenly fixedly installed on the outer wall of the water suction pipe 26; The inner wall of the water-locking pipe 22 is equipped with an inlet check valve; One end of the suction pipe 26 is equipped with an outflow check valve.

[0038] In specific implementation, both the inlet check valve and the outlet check valve are existing technologies and will not be explained in detail here. The inlet check valve and the outlet check valve are not shown in the figure. The inlet check valve is set inside the water-locking pipe 22, so that water can only enter the water-suction pipe 26 through the water-locking pipe 22 and cannot exit through the water-locking pipe 22. Therefore, after the water-locking pipe 22 sucks the water absorbed by the sponge into the water-suction pipe 26, the water will not flow back to the sponge pipe 2. The outlet check valve is set at the end of the water-suction pipe 26 away from the sealing plug 24. When the sealing plug 24 is reset after being moved, the air pressure inside the water-suction pipe 26 increases, and the water inside the water-suction pipe 26 will be pushed out of the water-suction pipe 26 through the outlet check valve.

[0039] like Figures 4-7 As shown, a water storage tray 5 is fixedly connected to one end of the rotating tube 21; A water outlet pipe is installed on the outer wall of the water storage pan 5; One end of the suction pipe 26 extends into the interior of the water storage pan 5.

[0040] In practice, the water inside the suction pipe 26 is pushed out of the suction pipe 26 through the outgoing one-way valve and then enters the water storage pan 5. The water storage pan 5 can store water. The external drainage pipe can also be installed with the outlet pipe through a rotary joint. Therefore, the water collected inside the water storage pan 5 can be processed. The rotary joint does not hinder the rotation of the water storage pan 5 and the outlet pipe, so it can be used during the operation of the sponge roller 2.

[0041] The suction component also includes a first spring 23 fixed to the inner wall of the suction tube 26; One end of the first spring 23 is fixedly connected to the sealing plug 24; The outer wall of the sealing plug 24 is slidably connected to the inner wall of the suction pipe 26; A pull rope 25 is fixedly connected to one side of the sealing plug 24.

[0042] A through groove is provided on the inner wall of the water suction pipe 26; The pull rope 25 is slidably connected to the through groove.

[0043] In practice, small ball bearings can be set at equal angles on the inner wall of the channel. Therefore, when the pull rope 25 is pulled, the frictional resistance can be reduced, the movement can be smoother, and there will be no jamming. At the same time, it also protects the pull rope 25 and the suction pipe 26 and reduces wear.

[0044] The driving component also includes a rotating roller 4 fixed to one end of the rotating tube 21; The drive column 41 is slidably sleeved with the rotating roller 4; A second spring 42 is fixedly installed at equal angles on the inner wall of the rotating roller 4; One end of the second spring 42 is fixedly connected to the mounting plate 43; Mounting plate 43 is fixedly connected to drive column 41.

[0045] In practice, when the two sponge rollers 2 rotate relative to each other, they simultaneously drive the two rotating rollers 4 to rotate relative to each other. When the two rotating rollers 4 rotate relative to each other, the two opposing drive columns 41 are subjected to mutual compression (e.g., Figures 7-9 As shown), the drive column 41 subjected to the squeezing force will slide into the interior of the rotating tube 21, and the second spring 42 will be stretched. When the two mutually squeezing drive columns 41 rotate to the point of disengagement, the two drive columns 41 will be reset by the second spring 42. Through the same principle, the other mutually squeezing drive columns 41 will slide into the interior of the rotating tube 21 through the same principle. That is to say, during the continuous operation of the sponge roller 2, the rotating tube 21 is continuously rotated by the motor, and the drive columns 41 distributed at equal angles will be squeezed against each other one by one. The drive columns 41 that are squeezed against each other are the two drive columns 41 that have rotated to the bottom and the top, respectively.

[0046] The rotating roller 4 has a circular ring structure; The end of the drive column 41 has an arc-shaped structure.

[0047] In practice, ball bearings can be installed on the arc-shaped structure of the drive column 41. When the two drive columns 41 are pressed and contacted with each other, the friction can be reduced, thereby reducing the wear of the contact surface of the drive column 41.

[0048] One end of the pull rope 25 is fixedly connected to one side of the drive column 41.

[0049] In specific implementation, such as Figures 10-11 As shown, when the drive column 41, subjected to the squeezing force, slides into the rotating tube 21, one end of the drive column 41 pulls the sealing plug 24 via the pull rope 25. Since the end of the suction pipe 26 is equipped with an outward one-way valve, preventing air or water from entering, the suction pipe 26 generates suction on the locking pipe 22 through negative pressure. The locking pipe 22 contacts the sponge roller 2, and at this time, the bottom of the sponge roller 2 is deformed by the steel, reducing its thickness. Therefore, the suction generated by the locking pipe 22 can absorb the water adsorbed by the sponge roller 2 (e.g., ...). Figure 10 As shown), the water-locking pipe 22 can exert a suction force on the steel through the gap of the sponge roller 2, thus further improving the water absorption effect on the steel. The water absorbed by the sponge roller 2 will be promptly sucked into the interior of the water-suction pipe 26, realizing the treatment of water in the sponge roller 2 without the need for a scraper to squeeze the sponge roller 2. When the two mutually squeezing drive columns 41 rotate to disengage from each other, the two drive columns 41 will be reset by the second spring 42, the pull rope 25 will no longer be pulled, and the sealing plug 24 will be reset by the first spring 23. At this time, since the water-locking pipe 22 is equipped with an inlet one-way valve, the water inside the water-suction pipe 26 will no longer exit through the water-locking pipe 22. The pressure inside the water-suction pipe 26 will push the water towards the outlet one-way valve (as shown). Figure 11 As shown in the figure, water enters the interior of the water storage pan 5 through the outgoing one-way valve.

[0050] An automated cutting process for steel with integrated pickling pretreatment includes the following steps: S1: The steel first passes through the pickling spraying mechanism 6 to be pickled by pickling liquid, and then passes through the cleaning spraying mechanism 7 to be cleaned by cleaning liquid to remove the residual pickling liquid. Then, before passing through the laser cutting machine 3, it passes through two sponge rollers 2. The sponge rollers 2 can absorb the moisture on the surface of the steel. The sponge rollers 2 have good deformation force and can adhere more fully to the surface of the steel when absorbing water from the steel plate. They can also absorb the moisture accumulated in the small pits on the surface of the steel. S2: When the two sponge rollers 2 rotate relative to each other, they drive the two rotating rollers 4 to rotate relative to each other. When the two rotating rollers 4 rotate relative to each other, the two driving columns 41 will be squeezed against each other. One end of the driving column 41 will pull the sealing plug 24 through the pull rope 25, so that the water suction pipe 26 will absorb the water on the sponge rollers 2. S3: When the two mutually pressing drive columns 41 rotate to disengage from each other, the two drive columns 41 are reset by the second spring 42, the pull rope 25 is no longer pulled, so the sealing plug 24 can be reset by the first spring 23, and the pressure inside the water suction pipe 26 will push the water to the outgoing one-way valve, and the water enters the interior of the water storage pan 5 through the outgoing one-way valve.

[0051] Working principle: When using this integrated automatic steel cutting equipment with pickling pretreatment, the steel is first placed on the conveyor frame 1. The steel is first pickled by the pickling solution through the pickling spray mechanism 6, and then it passes through the cleaning spray mechanism 7. The cleaning solution can wash away the residual pickling solution on the steel. Two drainage tanks are located below the pickling spray mechanism 6 and the cleaning spray mechanism 7, respectively. The pickling solution and the cleaning solution enter different drainage tanks, so the pickling solution and the cleaning solution can be collected separately, which is convenient for subsequent waste liquid treatment.

[0052] Before passing through the laser cutting machine 3, the steel passes through two sponge rollers 2. The sponge rollers 2 can absorb moisture from the surface of the steel. The outer wall of the sponge rollers 2 is honeycomb-shaped, which has good deformation force. When absorbing water from the steel plate, the sponge rollers 2 will also deform under the pressure. Therefore, the sponge rollers 2 can fit more fully against the surface of the steel. When the surface of the steel has small pits caused by rust corrosion, the sponge rollers 2 can also fill the small pits due to deformation and absorb the water accumulated in the small pits. The conveyor frame 1 is symmetrically equipped with motors (not shown in the figure). The two motors can drive the rotating tube 21 to rotate relative to each other, thereby causing the two sponge rollers 2 to rotate relative to each other. The two sponge rollers 2 will not affect the conveying of the steel during the water absorption process.

[0053] The two sponge rollers 2 rotate relative to each other, driving the two rotating rollers 4 to rotate relative to each other. When the two rotating rollers 4 rotate relative to each other, the two opposing drive columns 41 are subjected to mutual compression (e.g., ...). Figures 7-9 As shown), the drive column 41, subjected to the squeezing force, slides into the interior of the rotating tube 21 (the drive columns 41 that are squeezed against each other are the two drive columns 41 that have rotated to the bottom and top, respectively). The second spring 42 is stretched, and one end of the drive column 41 pulls the sealing plug 24 through the pull rope 25. Since the end of the water suction pipe 26 is equipped with an outward one-way valve, it will not allow air or water to enter. Therefore, the water suction pipe 26 will generate suction on the water-locking pipe 22 through negative pressure. The water-locking pipe 22 can absorb the water on the sponge roller 2 (such as...). Figure 10 (As shown).

[0054] In addition, the water-locking pipe 22 can exert a suction force on the steel through the gap of the sponge roller 2, thus further improving the water absorption effect on the steel. The water absorbed by the sponge roller 2 will be sucked into the interior of the water-absorbing pipe 26 in time, so that the water in the sponge roller 2 can be treated without the need for a scraper to squeeze the sponge roller 2.

[0055] like Figures 10-11 As shown, when the two mutually pressing drive columns 41 rotate to disengage, the two drive columns 41 are reset by the second spring 42, and the pull rope 25 is no longer pulled. Therefore, the sealing plug 24 can be reset by the first spring 23. At this time, because the water-locking pipe 22 is equipped with an inlet check valve, the water inside the water-suction pipe 26 will no longer exit through the water-locking pipe 22. The pressure inside the water-suction pipe 26 will push the water towards the outlet check valve. Figure 11 As shown, water enters the interior of the water storage pan 5 through the outgoing one-way valve.

[0056] The water storage pan 5 can store the water discharged from multiple suction pipes 26. The external drainage pipe can also be installed together with the water outlet pipe through a rotary joint. Therefore, the water collected inside the water storage pan 5 can be processed. The rotary joint does not hinder the rotation of the water storage pan 5 and the water outlet pipe, so it can be used during the operation of the sponge roller 2.

[0057] It should be noted that the water suction pipe 26 can remove most of the water from the sponge roller 2 through the water locking pipe 22. Some water may still remain in the sponge roller 2. This water will not affect the normal adsorption work of the sponge roller 2. After a batch of steel is processed, the equipment will stop for a period of time. During this period, the water remaining in the sponge roller 2 will also evaporate naturally, so it will not affect the subsequent work.

[0058] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

A process method for automatically cutting steel with integrated pickling pretreatment, applicable to the integrated automatic cutting equipment for steel with integrated pickling pretreatment as described in any one of claims 1 to 9, characterized in that, Includes the following steps: S1: The steel is first pickled by the pickling spray mechanism (6), and then cleaned by the cleaning spray mechanism (7) to remove the residual pickling liquid. Before passing through the laser cutting machine (3), it will pass through two sponge rollers (2). The sponge rollers (2) can absorb the moisture on the surface of the steel. The sponge rollers (2) have good deformation force and can adhere more fully to the surface of the steel when absorbing water from the steel plate. They can also absorb the moisture accumulated in the small pits on the surface of the steel. S2: The two sponge rollers (2) rotate relative to each other while driving the two rotating rollers (4) to rotate relative to each other. When the two rotating rollers (4) rotate relative to each other, the two driving columns (41) will be squeezed against each other. One end of the driving column (41) will pull the sealing plug (24) through the pull rope (25), so that the water suction pipe (26) will absorb the water on the sponge rollers (2). S3: When the two mutually pressing drive columns (41) rotate to disengage from each other, the two drive columns (41) are reset by the second spring (42), the pull rope (25) is no longer pulled, so the sealing plug (24) can be reset by the first spring (23), and the pressure inside the suction pipe (26) will push the water to the outgoing one-way valve, and the water enters the interior of the water storage pan (5) through the outgoing one-way valve.
