Description

Technical Field

[0001] The present invention relates to the technical field of metal sheet processing, and particularly to a pre-degreasing tank for phosphating treatment of metal sheets with a grease collection and filtration function. Background Art

[0002] The dirt adhered to metal sheets during machining mainly includes various working oils and material debris. Since various cutting oils, rolling oils, lubricating oils, and rust-preventive oils are used during the machining process, after the basic machining of the parts is completed, the oil attached to the surface of the sheet needs to be removed before the next phosphating treatment can be carried out. This step is the degreasing process.

[0003] The patent publication number of the existing patent application is: CN 211724785U, and the publication date is October 23, 2020. The name of this patent is "An oil removal system for a degreasing tank". This patent includes a pre-degreasing tank, a degreasing tank connected to the pre-degreasing tank, a circulation pump connected to the pre-degreasing tank, a heat exchanger and a first oil-water separator connected to the circulation pump in sequence through a reflux pipeline, and a vehicle body spray pipeline connected between the heat exchanger and the pre-degreasing tank; the first oil-water separator has two outlets, which are respectively connected to the degreasing tank and an oil and dirt collection barrel; one end of the degreasing tank away from the pre-degreasing tank is the first end, and a spray circulation pipeline is provided between the heat exchanger and the first end of the degreasing tank. A first on-off valve is provided on the spray circulation pipeline, and a second on-off valve is provided on the vehicle body spray pipeline. This oil removal system for the degreasing tank can greatly increase the oil removal amount, improve the oil removal efficiency, and is beneficial to effectively improving the quality.

[0004] The above application has deficiencies. The metal sheets can only be simply soaked, and the grease on the surface cannot be completely removed. At the same time, the grease in the tank is relatively concentrated, resulting in easy secondary deposition of grease suspensions on the surface of the sheets. When performing continuous degreasing operations, the degreasing liquid needs to be frequently replaced, otherwise it is difficult to ensure the degreasing effect. And if the grease on the surface of the sheets is scraped off mechanically, it is easy to cause surface scratches on the sheets, causing irreversible damage to the sheets. Summary of the Invention

[0005] The purpose of the present invention is to provide a pre-degreasing tank for phosphating treatment of metal sheets with a grease collection and filtration function to solve the above deficiencies in the prior art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A pre-degreasing tank for phosphating treatment of metal sheets with a grease collection and filtration function, comprising a tank body and a clamping and conveying mechanism located above the tank body, further comprising a movable storage rack, which is slidably installed in the tank body. A pair of grease suction rollers are symmetrically installed inside the movable storage rack, and a grease scraping assembly is coaxially installed on the grease suction rollers. There is an insertion opening between the two grease suction rollers for the clamping and conveying mechanism to clamp the metal sheet and vertically insert it into the movable storage rack. A dynamic filtration mechanism is movably inserted into the movable storage rack and is on the same vertical plane as the metal sheet. A linkage driving mechanism is installed on the movable storage rack and drives the grease suction rollers and the dynamic filtration mechanism to drive each other. When the movable storage rack drives the linkage driving mechanism to move horizontally, it drives the grease suction rollers, the grease scraping assembly and the dynamic filtration mechanism to move up and down, and when the grease scraping assembly moves up, it separates from the surface of the metal sheet.

[0008] Preferably, the clamping and conveying mechanism includes a frame installed outside the tank body, an electric translation seat movably installed on the frame, and a lifting clamp fixed to the bottom of the electric translation seat.

[0009] Preferably, the grease scraping assembly includes a pair of adjusting cams rotatably installed on the roller shafts of the grease suction rollers. A scraping bar is installed between the two adjusting cams and is located below the grease suction rollers. A resisting rod that abuts and cooperates with the convex part of the adjusting cam is vertically and fixedly connected to the inner side wall of the movable storage rack.

[0010] Preferably, guide sliding grooves are symmetrically and vertically opened on both sides of the movable storage rack, and a pair of guide sliding grooves on the same side are symmetrical to each other. Connecting seats are vertically and slidably installed on both sides of the movable storage rack. The roller ends of the two grease suction rollers respectively penetrate through the guide sliding grooves and are connected to the connecting seats.

[0011] Preferably, the dynamic filtration mechanism includes a pair of grease suction filter meshes. A counterweight rod is fixedly connected to the top of the grease suction filter meshes. An insertion sliding groove for the counterweight rod to enter is opened on the top of the movable storage rack.

[0012] Preferably, the linkage driving mechanism includes a transmission shaft rod horizontally and rotatably installed at the bottom of the movable storage rack and transmission lead screws respectively vertically and rotatably installed on both sides of the movable storage rack. Transmission gears are fixedly connected to both ends of the transmission shaft rod. A transmission rack meshing with the transmission gears is arranged at the bottom of the tank body along the moving direction of the movable storage rack. The bottom ends of the two transmission lead screws are respectively meshed and driven with the transmission shaft rod, and the transmission lead screws threadedly penetrate through the connecting seats.

[0013] Preferably, a pair of abutting cams are fixedly sleeved on the transmission shaft rod. The abutting cams are located below the dynamic filtration mechanism and abut and cooperate with it.

[0014] Preferably, a limit snap ring matched with the guiding sliding groove is installed on one side of the adjusting cam, and a torsion spring is arranged between the adjusting cam and the limit snap ring.

[0015] Preferably, a speed-regulating rack is vertically and fixedly connected to one side of the abutting rod, and a driven gear ring matched with the speed-regulating rack is fixedly connected to the end face of the fat-absorbing roller.

[0016] Preferably, an inclined rod is fixedly connected to the bottom of the adjusting cam, and an abutting column is rotatably connected to one side of the inclined rod. When the convex part of the adjusting cam flips downward, the abutting column is in abutting cooperation with the driven gear ring.

[0017] In the above technical solution, through the bidirectional rotation adsorption of the fat-absorbing roller and the phase control of the fat-scraping assembly, the collaborative operation of contact-type mobile cleaning and non-contact displacement is realized, so that the fat-absorbing roller and the fat-scraping assembly perform a full-range fat-absorbing and fat-scraping operation on the plate in the degreasing tank, and the fat-scraping assembly can be separated from the plate after the fat scraping is completed. While ensuring the grease removal rate, mechanical scratches are eliminated. And when the plate and the mobile storage rack move in the tank, the remaining degreasing liquid in the tank will be deflected to both sides, causing it to flow through the dynamic filtering mechanism. The dynamic filtering mechanism continuously reciprocates up and down under the drive of the linkage drive mechanism, captures and filters the grease in the tank, and at the same time shakes the degreasing liquid that has not been captured in the tank to prevent the grease generated after multiple degreasings from accumulating in the tank.

[0018] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not intended to limit the present disclosure.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0032] Please refer to Figure 1-8, a pre-degreasing tank for phosphating treatment of metal sheets with a grease collecting and filtering function provided by an embodiment of the present invention includes a tank body 1 and a clamping and conveying mechanism 2 located above the tank body 1, and further includes a movable storage rack 3 which is slidably installed in the tank body 1. Symmetrically installed inside the movable storage rack 3 are oil-absorbing rollers 4, coaxially installed on the oil-absorbing rollers 4 are grease scraping components 5, there is an insertion opening 6 between the two oil-absorbing rollers 4 for the clamping and conveying mechanism 2 to clamp the sheet and vertically insert it into the movable storage rack 3, a dynamic filtering mechanism 7 which is movably inserted into the movable storage rack 3 and is on the same vertical plane as the metal sheet, and a linkage driving mechanism 8 which is installed on the movable storage rack 3 and drives the oil-absorbing rollers 4 and the dynamic filtering mechanism 7 to drive each other. When the movable storage rack 3 drives the linkage driving mechanism 8 to move horizontally, it drives the oil-absorbing rollers 4, the grease scraping components 5 and the dynamic filtering mechanism 7 to move up and down, and when the grease scraping components 5 move up, they are separated from the surface of the sheet.

[0033] Specifically, the movable storage rack 3 moves horizontally in the tank body 1. Guide rails 12 are installed on both sides of the inner wall of the tank body 1. The two sides of the movable storage rack 3 have sliding rods 34 inserted into the corresponding guide rails 12, so as to achieve stable sliding. The two oil-absorbing rollers 4 symmetrically installed inside the movable storage rack 3 are installed on the movable storage rack 3 through roller shafts and can rotate freely. The oil-absorbing rollers 4 are made of oil-absorbing materials, and there are also oil-draining holes provided. When the clamping and conveying mechanism 2 clamps the sheet and inserts it from above into the insertion opening 6 between the two oil-absorbing rollers 4, the two oil-absorbing rollers 4 respectively come into frictional contact with both sides of the sheet to adsorb and degrease the grease on the surface of the sheet. At the same time, the grease scraping components 5 scrape off the grease and impurities that are difficult to adsorb on the surface of the sheet. Since the metal sheet clamped by the clamping and conveying mechanism 2 has been inserted into the movable storage rack 3, when the clamping and conveying mechanism 2 drives the sheet to move, the movable storage rack 3 will also move in the tank body 1. During the movement of the sheet and the movable storage rack 3, a pair of oil-absorbing rollers 4 move up and down under the drive of the linkage driving mechanism 8, so that the oil-absorbing rollers 4 continue to roll and absorb oil on the surface of the sheet in the degreasing liquid. At the same time, the moving sheet will also deflect the degreasing liquid in the tank to both sides, so as to flow through the dynamic filtering mechanism 7. The dynamic filtering mechanism 7 can continuously reciprocate up and down under the drive of the linkage driving mechanism 8, not only capturing and filtering the grease, but also shaking the degreasing liquid through its own lifting action during movement to reduce the accumulation of grease in the tank. The sheet moves in one direction in the tank first. At this time, the oil-absorbing rollers 4 move down. Then the sheet is made to move in the opposite direction. At this time, the oil-absorbing rollers 4 move up, and the grease scraping components 5 are separated from the surface of the sheet to avoid scratches caused by multiple scraping treatments. After the reciprocating movement and degreasing treatment are completed, the movable storage rack 3 returns to the initial position, and the clamping and conveying mechanism 2 takes out the sheet from the movable storage rack 3, and then proceeds to the next process. The degreasing liquid is continuously recycled through the circulation pump at the bottom of the tank body 1, and is replaced or purified regularly to maintain the treatment effect.

[0034] Compared with the prior art, in the embodiment of the present invention, through the bidirectional rotation adsorption of the fat suction roller 4 and the phase control of the fat scraping assembly 5, the collaborative operation of contact moving cleaning and non-contact displacement is realized, enabling the fat suction roller 4 and the fat scraping assembly 5 to perform comprehensive fat suction and fat scraping operations in the degreasing liquid, and also enabling the fat scraping assembly 5 to be separated from the sheet after the fat scraping is completed, eliminating mechanical scratches while ensuring the grease removal rate. Moreover, when the sheet and the movable storage rack 3 move in the pool, the degreasing liquid in the pool will be deflected to both sides, flowing through the dynamic filtering mechanism 7. The dynamic filtering mechanism 7 continuously reciprocates up and down under the drive of the linkage drive mechanism 8, capturing and filtering the grease in the pool, and simultaneously oscillating the degreasing liquid that has not been captured in the pool to prevent the grease generated after multiple degreasing operations from accumulating in the pool.

[0035] In a further embodiment of the present invention, the clamping and conveying mechanism 2 includes a frame 21 installed outside the pool body 1. An electric translation seat 22 is movably installed on the frame 21. A lifting clamp 23 is fixed to the bottom of the electric translation seat 22. The electric translation seat 22 is movably installed on the frame 21 and realizes horizontal movement through motor drive. The moving range of the electric translation seat 22 can cover most of the area above the pool body 1 to convey the sheet from one side of the pool body 1 to the other side. The lifting clamp 23 is fixedly installed at the bottom of the electric translation seat 22 and is used for clamping and conveying the metal sheet. The clamp is composed of one or more pairs of adjustable clamping arms, and enough space is left between the clamping arms to accommodate sheets of different thicknesses. Through a driving device such as a hydraulic cylinder, the lifting clamp 23 can realize vertical up and down movement, so as to conveniently send the sheet into or take it out of the movable storage rack 3 in the pool body 1. Specifically, the clamping and conveying mechanism 2 horizontally moves to one side of the pool body 1 through the electric translation seat 22 on the frame 21, then the lifting clamp 23 descends and clamps the metal sheet to be processed. Next, the electric translation seat 22 drives the sheet and the lifting clamp 23 to move to the socket 6 above the pool body 1. At this time, the lifting clamp 23 descends again, vertically inserts the sheet into the movable storage rack 3, and makes the sheet contact the fat suction roller 4 and the fat scraping assembly 5.

[0036] In a further embodiment of the present invention, the fat scraping assembly 5 includes a pair of adjusting cams 51 rotatably mounted on the roller shaft of the fat suction roller 4. The outer side surface of the adjusting cam 51 elastically abuts against the movable storage rack 3. A scraping strip 52 is installed between the two adjusting cams 51, and the scraping strip 52 is located below the fat suction roller 4. A resisting rod 35 that abuts against the protruding part of the adjusting cam 51 is vertically and fixedly connected to the inner side wall of the movable storage rack 3. Specifically, the scraping strip 52 is made of wear-resistant and elastic material to ensure that when scraping fat, it can effectively remove residues without damaging the surface of the fat suction roller 4. The two ends of the scraping strip 52 are fixed to the corresponding adjusting cams 51 and are adjusted by flipping as the adjusting cams 51 rotate. When the adjusting cam 51 is above the scraping strip 52, when the fat suction roller 4 drives the entire fat scraping assembly 5 to descend, the protruding part of the adjusting cam 51 will abut against the top of the scraping strip 52, forcing the protruding part of the adjusting cam 51 to flip upward and continuously abut against the resisting rod 35, so that the scraping strip 52 can always be in contact with the surface of the plate to complete the initial fat scraping treatment until the adjusting cam 51 moves below the resisting rod 35. At this time, during the process of the fat suction roller 4 resetting and moving upward, the protruding part of the adjusting cam 51 abuts against the bottom of the resisting rod 35 again, forcing the adjusting cam 51 to rotate downward, so that the scraping strip 52 is no longer in close contact with the surface of the plate, thus avoiding scratches caused by the continuous friction of the scraping strip 52 on the plate after degreasing is completed.

[0037] In a further embodiment of the present invention, guiding sliding grooves 31 are symmetrically and vertically formed on both sides of the movable storage rack 3, and a pair of guiding sliding grooves 31 on the same side are symmetric with each other. The guiding sliding groove 31 is provided with a first vertical section, an inclined section and a second vertical section from top to bottom. In a pair of guiding sliding grooves 31 on the same side, the distance between two first vertical sections is greater than the distance between second vertical sections. Connecting seats 32 are vertically and slidably installed on both sides of the movable storage rack 3. The roller ends of the two fat suction rollers 4 respectively penetrate through the guiding sliding grooves 31 and are connected to the connecting seats 32. Specifically, when the movable storage rack 3 is in the initial position, the rollers on a pair of fat suction rollers 4 are on the first vertical sections. At this time, the distance between the two fat suction rollers 4 is relatively large, so that the board can be quickly inserted into the movable storage rack 3. When the movable storage rack 3 starts to move, the linkage driving mechanism 8 makes the two connecting seats 32 drive the rollers of a pair of fat suction rollers 4 to move up and down along the path of the guiding sliding grooves 31. During the downward movement of the fat suction rollers 4, the rollers sequentially pass through the first vertical section, the inclined section and the second vertical section. Due to the design of the inclined section, the two rollers gradually approach each other, and the fat suction rollers 4 also adjust their positions accordingly, so that the rollers reach the second vertical section. At this time, the fat suction rollers 4 are in a new and closer position, which helps to further improve the defatting and cleaning effect, and can discharge the grease originally adsorbed into the fat suction rollers 4 by applying force through mutual extrusion, so that it diffuses onto the degreasing liquid. Through the cooperative action of the lifting of the connecting seat 32 and the guiding sliding grooves 31, the fat suction rollers 4 can achieve precise position adjustment according to needs, thereby optimizing the defatting process.

[0038] In a further embodiment of the present invention, the dynamic filtering mechanism 7 includes a pair of fat suction filter meshes 71. A counterweight rod 72 is fixedly connected to the top of the fat suction filter mesh 71. A plugging sliding groove 33 for the counterweight rod 72 to enter is formed on the top of the movable storage rack 3. Specifically, during the defatting process, the fat suction filter meshes 71 are placed in the movable storage rack 3 and kept stable through the cooperation of the counterweight rod 72 and the plugging sliding groove 33. As the board moves to stir the degreasing liquid, the degreasing liquid flowing to both sides of the board quickly passes through the fat suction filter meshes 71, and the grease and impurities are captured by the fat suction filter meshes 71. Due to the existence of the counterweight rod 72, the filter meshes can maintain their positions stable, and even the accumulation of grease and impurities will not cause the filter meshes to move or turn over. In addition, the design of the plugging sliding groove 33 facilitates the quick cleaning or replacement of the filter meshes when needed to adapt to different defatting requirements. In this way, the dynamic filtering mechanism 7 can efficiently remove the grease and impurities generated during the defatting process, thereby improving the defatting efficiency and effect.

[0039] In a further embodiment of the present invention, the linkage drive mechanism 8 includes a transmission shaft rod 81 horizontally and rotatably installed at the bottom of the movable storage rack 3 and transmission lead screws 82 vertically and rotatably installed on both sides of the movable storage rack 3 respectively. Both ends of the transmission shaft rod 81 are fixedly connected with transmission gears 83. A transmission rack 11 meshing with the transmission gears 83 is arranged at the bottom of the pool body 1 along the moving direction of the movable storage rack 3. The bottom ends of the two transmission lead screws 82 are meshed and driven with the transmission shaft rod 81 through bevel gears respectively, and the transmission lead screws 82 threadedly penetrate through the connecting seat 32. Specifically, the transmission gears 83 at both ends of the transmission shaft rod 81 are meshed with the transmission rack 11 at the bottom of the pool body 1, so as to convert linear motion into rotational motion when the movable storage rack 3 translates, and then transmit the driving force. The bottom ends of the two transmission lead screws 82 are meshed and driven with the transmission shaft rod 81 through bevel gears. In this way, when the transmission shaft rod 81 rotates, it can drive the two transmission lead screws 82 to rotate synchronously. When the transmission lead screw 82 rotates, the connecting seat 32 will move up and down along the lead screw, so that when the movable storage rack 3 and the plate move horizontally in the pool, the connecting seats 32 on both sides drive the fat suction roller 4 and the fat scraping assembly 5 to move up and down, ensuring the comprehensiveness of degreasing.

[0040] In a further embodiment of the present invention, a pair of abutting cams 84 are fixedly sleeved on the transmission shaft rod 81. The abutting cams 84 are located below the dynamic filtering mechanism 7 and are in abutting cooperation with it. Specifically, when the transmission shaft rod 81 rotates under the action of the linkage drive mechanism 8, a pair of abutting cams 84 fixedly sleeved on it will also rotate synchronously. As the abutting cams 84 rotate, the interaction between the contour shape of the abutting cams 84 and the bottom abutting part of the dynamic filtering mechanism 7 produces a periodic lifting effect. This periodic motion not only helps the dynamic filtering mechanism 7 capture and remove oil and impurities more effectively during the degreasing process, but also can reduce the risk of filter screen blockage to a certain extent and improve the filtering efficiency. In addition, it can also oscillate the degreasing liquid to avoid the accumulation of oil generated after multiple degreasings in the pool.

[0041] In a further embodiment of the present invention, a limit snap ring 54 matching with the guiding chute 31 is installed on one side of the adjusting cam 51, and a torsion spring 55 is arranged between the adjusting cam 51 and the limit snap ring 54. Specifically, the adjusting cam 51 presses the limit snap ring 54 tightly against the guiding chute 31 through the torsion spring 55. The limit snap ring 54 can prevent the adjusting cam 51 from rotating too much due to the friction of the roller shaft of the fat suction roller 4, and keep the adjusting cam 51 at a relatively static angle when it is not in contact with the abutting rod 35, so that when the adjusting cam 51 is above the abutting rod 35, its protruding part is above, so that when moving down, the adjusting cam 51 flips upwards by a certain angle, and the scraping strip 52 is tightly attached to the surface of the plate for efficient fat scraping.

[0042] In a further embodiment of the present invention, a speed regulation rack 36 is vertically and fixedly connected to one side of the abutting rod 35, and a driven gear ring 41 matching the speed regulation rack 36 is fixedly connected to the end face of the fat suction roller 4. Specifically, when the driven gear ring 41 on the fat suction roller 4 is above or below the speed regulation gear, the rotation of the fat suction roller 4 itself is driven by the frictional force between it and the plate. The slower the plate moves, the slower the fat suction roller 4 rotates. When the driven gear ring 41 and the speed regulation rack 36 are engaged together, the rotation generated by the engagement of the driven gear during lifting with the speed regulation rack 36 drives the fat suction roller 4, enabling the fat suction roller 4 to rotate rapidly on the surface of the plate, increasing the number of frictions to meet the requirement of rapid and effective degreasing, and further improving the working efficiency.

[0043] In a further embodiment of the present invention, an inclined rod 57 is fixedly connected to the bottom of the adjusting cam 51, and an abutting column 58 is rotatably connected to one side of the inclined rod 57. When the convex part of the adjusting cam 51 turns downward, the abutting column 58 abuts and cooperates with the driven gear ring 41. Specifically, when the adjusting cam 51 moves upward while abutting against the abutting rod 35 from below, the adjusting cam 51 rotates clockwise, making the position of the abutting column 58 in the tooth groove of the driven gear ring 41. When the driven gear ring 41 rotates, its teeth will intermittently contact and push the abutting column 58, causing the scraping strip 52 that has been separated from the plate to vibrate, thereby quickly cleaning the grease and impurities attached to the scraping strip 52 to improve the effect during the fat scraping operation.

[0044] Only some exemplary embodiments of the present invention have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
