Description

Technical Field

[0001] The invention relates to the technical field of metal plate processing, in particular to a metal plate phosphating treatment pre-degreasing pool with fat collecting and filtering functions. Background Art

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

[0003] The existing patent application has the publication number CN 211724785U, published on October 23, 2020. The patent is titled "A Degreasing Tank Deoiling System." The patent includes a pre-degreasing tank, a degreasing tank connected to the pre-degreasing tank, a circulating pump connected to the pre-degreasing tank, a heat exchanger and a first oil-water separator connected in sequence to the circulating pump via a return line, and a body spray pipe connected between the heat exchanger and the pre-degreasing tank. The first oil-water separator has two outlets, connecting the degreasing tank and an oil collection bucket, respectively. The degreasing tank has a first end that is away from the pre-degreasing tank. A spray circulation pipe 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 pipe, and a second on-off valve is provided on the body spray pipe. This degreasing tank deoiling system can significantly increase the amount of oil removed, improve oil removal efficiency, and effectively improve quality.

[0004] The above application has shortcomings. The metal plate can only be simply immersed, and the grease on the surface cannot be completely removed. At the same time, the grease in the pool is relatively concentrated, which makes it easy for the grease suspension to be deposited again on the surface of the plate. The degreasing liquid needs to be frequently replaced during continuous degreasing operations, otherwise it is difficult to ensure the degreasing effect. If the grease on the surface of the plate is scraped off mechanically, it is easy to cause surface scratches on the plate, causing irreversible damage to the plate. Summary of the Invention

[0005] The purpose of the present invention is to provide a metal plate phosphating pre-degreasing tank with fat collecting and filtering functions to solve the deficiencies in the above-mentioned prior art.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0016] Preferably, the bottom of the adjusting cam is fixedly connected with an inclined rod, and one side of the inclined rod is rotatably connected with an abutment column. When the raised portion of the adjusting cam flips downward, the abutment column abuts and cooperates with the driven gear ring.

[0031] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0032] See also Figure 1-8The embodiment of the present invention provides a metal plate phosphating pre-degreasing pool with fat collecting and filtering functions, comprising a pool body 1 and a clamping and conveying mechanism 2 located above the pool body 1, and also comprising a movable rack 3, which is slidably installed in the pool body 1, and a fat suction roller 4 is symmetrically installed inside the movable rack 3, and a fat scraping assembly 5 is coaxially installed on the fat suction roller 4, and a socket 6 is provided between the two fat suction rollers 4 for the clamping and conveying mechanism 2 to clamp the plate and vertically insert it into the movable rack 3, a dynamic filtering mechanism 7, which is movably inserted in the movable rack 3 and is on the same vertical plane as the metal plate, a linkage driving mechanism 8, which is installed on the movable rack 3 and enables mutual transmission between the fat suction roller 4 and the dynamic filtering mechanism 7, when the movable rack 3 drives the linkage driving mechanism 8 to move horizontally, the fat suction roller 4, the fat scraping assembly 5 and the dynamic filtering mechanism 7 are driven to move up and down, and the fat scraping assembly 5 is separated from the surface of the plate when it moves up.

[0033] When the plate is moved, the two rollers 4 are moved along the guide rails 12 and the two rollers 4 are moved along the guide rails 12 so as to slide smoothly. The grease is filtered out by the filter mechanism 7 and the filter mechanism 7 is moved back and forth, and the filter mechanism 7 is moved back and forth, so that the filter mechanism 7 can filter the grease and grease by the filter mechanism 7. The filter mechanism 7 can filter the grease and grease by the filter mechanism 7. The filter mechanism 7 can filter the grease and grease by the filter mechanism 7. The filter mechanism 7 can filter the grease and grease by the filter mechanism 7.

[0034] Compared with the prior art, the embodiment of the present invention realizes the coordinated operation of contact mobile cleaning and contactless displacement through the bidirectional rotation adsorption of the grease suction roller 4 and the phase control of the scraping component 5, so that the grease suction roller 4 and the scraping component 5 can perform comprehensive grease suction and scraping operations in the degreasing liquid, and the scraping component 5 can be separated from the plate after the scraping is completed, thereby eliminating mechanical scratches while ensuring the grease removal rate. When the plate and the mobile storage rack 3 move in the pool, the degreasing liquid in the pool will be pushed to both sides to flow through the dynamic filtering mechanism 7. The dynamic filtering mechanism 7 is driven by the linkage driving mechanism 8 to continuously reciprocate and rise and fall, capture and filter the grease in the pool, and at the same time oscillate the degreasing liquid that has not been captured in the pool, so as to avoid the grease generated after multiple degreasing 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, and 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 is driven by a motor to achieve horizontal movement. The moving range of the electric translation seat 22 can cover most of the area above the pool body 1 so as to convey the plate 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 for clamping and conveying the metal plate. The clamp consists of one or more pairs of adjustable clamping arms, with sufficient space between the clamping arms. The space is large enough to accommodate plates of different thicknesses. Through driving devices such as hydraulic cylinders, the lifting clamp 23 can move up and down in the vertical direction, so that the plates can be easily sent into or taken out of the mobile storage rack 3 in the pool body 1. Specifically, the clamping and conveying mechanism 2 moves horizontally to one side of the pool body 1 through the electric translation seat 22 on the frame 21, and then the lifting clamp 23 descends and clamps the metal plate to be processed. Then, the electric translation seat 22 drives the plate and the lifting clamp 23 to move together to the socket 6 above the pool body 1. At this time, the lifting clamp 23 descends again and inserts the plate vertically into the mobile storage rack 3, allowing the plate to contact the liposuction roller 4 and the fat scraping assembly 5.

[0036] In a further embodiment of the present invention, the grease scraping assembly 5 includes a pair of adjusting cams 51 rotatably mounted on the roller shaft of the grease suction roller 4. The outer side surface of the adjusting cam 51 elastically abuts against the movable rack 3. A scraping strip 52 is installed between the two adjusting cams 51, and the scraping strip 52 is located below the grease suction roller 4. The inner side wall of the movable rack 3 is vertically fixedly connected with a push rod 35 that abuts against the raised portion of the adjusting cam 51. Specifically, the scraping strip 52 is made of wear-resistant elastic material to ensure that the residue can be effectively removed when scraping grease without damaging the surface of the grease suction roller 4. The two ends of the scraping strip 52 are fixed on the corresponding adjusting cams 51, and the whole is flipped and adjusted as the adjusting cam 51 rotates. When the adjusting cam 51 is located above the scraping bar 52, when the liposuction roller 4 descends with the entire scraping assembly 5, the raised part of the adjusting cam 51 will abut against the top of the scraping bar 52, forcing the raised part of the adjusting cam 51 to flip upward and continuously abut against the push rod 35, so that the scraping bar 52 can always be inserted into the plate surface to complete the initial scraping process, until the adjusting cam 51 moves to the bottom of the push rod 35. At this time, during the process of resetting and moving upward of the liposuction roller 4, the raised part of the adjusting cam 51 again abuts against the bottom of the push rod 35, forcing the adjusting cam 51 to rotate downward, so that the scraping bar 52 is no longer in contact with the surface of the plate, thereby avoiding scratches caused by the scraping bar 52 continuously rubbing the plate after degreasing is completed.

[0037] In a further embodiment of the present invention, guide slots 31 are symmetrically and vertically opened on both sides of the movable rack 3, and a pair of guide slots 31 located on the same side are symmetrical to each other, and the guide slots 31 are provided with a first vertical section, an inclined section and a second vertical section from top to bottom. In a pair of guide slots 31 on the same side, the spacing between the two first vertical sections is greater than the spacing between the second vertical sections. Connecting seats 32 are vertically slidably installed on both sides of the movable rack 3, and the roller ends of the two liposuction rollers 4 respectively pass through the guide slots 31 and are connected to the connecting seats 32. Specifically, when the movable rack 3 is in the initial position, the roller shafts on the pair of liposuction rollers 4 are on the first vertical section. At this time, the spacing between the two liposuction rollers 4 is large, which facilitates the rapid insertion of the plate into the movable rack 3. When the movable rack 3 starts to move When the grease suction roller 4 is in motion, the linkage drive mechanism 8 causes the two connecting seats 32 to drive the roller shafts of a pair of grease suction rollers 4 to move up and down along the path of the guide slot 31. In the process of the grease suction roller 4 moving downward, the roller shafts pass through the first vertical section, the inclined section and the second vertical section in sequence. Due to the design of the inclined section, the two roller shafts gradually approach each other, and the grease suction roller 4 also adjusts its position accordingly to allow the roller shaft to reach the second vertical section. At this time, the grease suction roller 4 is in a new, tighter position, which helps to further improve the degreasing and cleaning effect, and can discharge the grease originally absorbed into the grease suction roller 4 by applying force through mutual squeezing, allowing it to diffuse into the degreasing liquid. Through the synergistic effect of the lifting and lowering of the connecting seat 32 and the guiding slot 31, the grease suction roller 4 can be precisely adjusted in position as needed, thereby optimizing the degreasing process.

[0038] In a further embodiment of the present invention, the dynamic filtering mechanism 7 includes a pair of fat-absorbing filters 71, the top of which is fixedly connected to a counterweight rod 72, and the top of the movable rack 3 is provided with a plug-in slot 33 for the counterweight rod 72 to enter. Specifically, during the degreasing process, the fat-absorbing filter 71 is placed in the movable rack 3 and is kept stable by the cooperation of the counterweight rod 72 and the plug-in slot 33. As the plate moves, the degreasing liquid is moved, and the degreasing liquid flowing to both sides of the plate quickly passes through the fat-absorbing filter 71, and grease and impurities are captured by the fat-absorbing filter 71. Due to the presence of the counterweight rod 72, the filter can maintain its position stable, and even if grease and impurities accumulate, it will not cause the filter to move or flip. In addition, the design of the plug-in slot 33 facilitates the quick cleaning or replacement of the filter when needed to meet different degreasing requirements. In this way, the dynamic filtering mechanism 7 can effectively remove grease and impurities generated during the degreasing process, thereby improving the degreasing efficiency and effect.

[0039] In a further embodiment of the present invention, the linkage drive mechanism 8 includes a transmission shaft 81 horizontally mounted on the bottom of the mobile rack 3 and a transmission screw 82 vertically mounted on both sides of the mobile rack 3. Both ends of the transmission shaft 81 are fixedly connected to a transmission gear 83. A transmission rack 11 meshing with the transmission gear 83 is provided at the bottom of the pool body 1 along the moving direction of the mobile rack 3. The bottom ends of the two transmission screws 82 are respectively meshed with the transmission shaft 81 through helical gears, and the transmission screw 82 threads penetrate the connecting seat 32. Specifically, the transmission gears 83 at both ends of the transmission shaft 81 are fixedly connected to the transmission gear 83. It is engaged with the transmission rack 11 at the bottom of the pool body 1, thereby converting the linear motion into rotational motion when the mobile storage rack 3 is translated, and then transmitting the driving force. The bottom ends of the two transmission screws 82 are engaged with the transmission shaft 81 through the bevel gear. In this way, when the transmission shaft 81 rotates, it can drive the two transmission screws 82 to rotate synchronously. When the transmission screw 82 rotates, the connecting seat 32 will move up and down along the screw, so that when the mobile storage rack 3 and the plate move horizontally in the pool, the connecting seats 32 on both sides move up and down with the liposuction roller 4 and the fat scraping assembly 5 to ensure comprehensive degreasing.

[0040] In a further embodiment of the present invention, a pair of abutment cams 84 are fixedly sleeved on the transmission shaft 81, and the abutment cams 84 are located below the dynamic filtering mechanism 7 and abut against it. Specifically, when the transmission shaft 81 rotates under the action of the linkage drive mechanism 8, the pair of abutment cams 84 fixedly sleeved thereon will also rotate synchronously. As the abutment cams 84 rotate, their contour shape interacts with the bottom abutment part of the dynamic filtering mechanism 7 to produce a periodic lifting effect. This periodic movement not only helps the dynamic filtering mechanism 7 to more effectively capture and remove grease and impurities in the degreasing process, but also reduces the risk of filter clogging to a certain extent and improves the filtration efficiency. In addition, the degreasing liquid can also be vibrated to avoid the accumulation of grease generated after multiple degreasing in the pool.

[0041] In a further embodiment of the present invention, a limiting snap ring 54 that cooperates with the guide slot 31 is installed on one side of the adjusting cam 51, and a torsion spring 55 is provided between the adjusting cam 51 and the limiting snap ring 54. Specifically, the adjusting cam 51 presses the limiting snap ring 54 against the guide slot 31 through the torsion spring 55. The limiting snap ring 54 can prevent the adjusting cam 51 from rotating too much due to the friction of the roller shaft of the liposuction roller 4, so that the adjusting cam 51 maintains a relatively static angle when it is not in contact with the push rod 35, so that when the adjusting cam 51 is above the push rod 35, its raised part is at the top, so that when the adjusting cam 51 moves downward, it flips upward by a certain angle, allowing the scraper 52 to stick to the surface of the plate for efficient grease scraping.

[0042] In a further embodiment of the present invention, a speed regulating rack 36 is vertically fixedly connected to one side of the support rod 35, and a driven gear ring 41 matching the speed regulating rack 36 is fixedly connected to the end face of the liposuction roller 4. Specifically, when the driven gear ring 41 on the liposuction roller 4 is above or below the speed regulating gear, the rotation of the liposuction roller 4 itself is driven by the friction between it and the plate. The slower the plate moves, the slower the liposuction roller 4 rotates. When the driven gear ring 41 and the speed regulating rack 36 are meshed together, the liposuction roller 4 is driven by the rotation generated by the engagement of the driven gear with the speed regulating rack 36 when it is raised and lowered, so that the liposuction roller 4 can rotate quickly on the surface of the plate, increase the number of frictions to meet the needs of fast and effective degreasing, and further improve work 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 abutment column 58 is rotatably connected to the inclined rod 57. When the raised portion of the adjusting cam 51 flips downward, the abutment column 58 abuts and cooperates with the driven gear ring 41. Specifically, when the adjusting cam 51 moves up from below against the abutment rod 35, the adjusting cam 51 rotates clockwise, so that the position of the abutment column 58 is 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 abutment column 58, causing the scraper 52 that has been separated from the plate to vibrate, thereby quickly cleaning off the grease and impurities attached to the scraper 52, so as to improve the effect of the connection scraping operation.

[0044] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various 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.
