Description

Technical Field

[0001] This invention relates to the field of shelf processing technology, and in particular to an integrated phosphate coating and dip-coating treatment device for evaporator steel wire shelves. Background Technology

[0002] When using evaporator wire shelves inside medical refrigerators, extremely high requirements are placed on the surface's corrosion resistance and sterility. Existing production processes typically involve dip coating on the shelf surface, and the wire skeleton must undergo pretreatment such as degreasing, pickling, and phosphating before dip coating to enhance the adhesion of the plastic coating. However, to achieve automated continuous production, existing technologies can sequentially feed the shelves into each stage of the process flow according to the process sequence, thereby performing continuous and integrated surface treatment.

[0003] However, in this existing continuous processing device, during the transition from the phosphating pretreatment process to the dip coating process, the mechanical moving parts such as the upper screw drive mechanism, guide rails, and cylinders require grease lubrication during long-term high-frequency operation. These lubricants are easily diluted and drip down under mechanical vibration. At the same time, after the transport vehicle is soaked or sprayed in the processing section, residual degreasing liquid, pickling liquid, or phosphating liquid will adhere to its structural surface and dead corners. Since the transport vehicle is not completely in the area of ​​the subsequent heating process, there will be liquid residue. In the subsequent transport process, the residual liquid will also drip down. If the residual liquid drips into the subsequent dip coating tank, it will cause the fluidized plastic powder in the fluidized bed to become damp, contaminated, clump, or chemically deteriorated instantly. This will not only cause the plastic powder to be scrapped, but will also form pinholes, shrinkage cavities, or blind spots on the surface of the medical shelf grid, seriously affecting the processing quality and service life of the medical equipment.

[0012] Preferably, a sliding groove is provided in the middle of both ends of the liquid receiving tray, the top of the sliding groove extends through the top of the liquid receiving tray, a sliding plate is slidably connected to the liquid receiving tray inside the sliding groove, a friction strip is provided at the top of the sliding plate, limit grooves are provided at both ends of the sliding plate, a limit pin matching the limit groove is installed on the side wall of the liquid receiving tray in the sliding groove, and the top of the sliding plate is slidably connected to the surface of the bottom of the anti-overflow flap.

A float is slidably connected to the bottom of the surface of the vertical guide rod. The float is configured as a right trapezoid with the upper bottom side longer than the lower bottom side. The hypotenuse of the float faces the middle of the liquid receiving tray. A pull rope is connected to the top of the vertical guide rod.

[0014] Preferably, a telescopic rod is rotatably connected to the surface of the driven block, and the other end of the telescopic rod is rotatably connected to the inside of the sliding plate. A buffer spring is provided inside the telescopic rod.

[0015] Compared with the prior art, the present invention provides an integrated phosphate coating and dip-coating treatment device for evaporator wire racks, which has the following beneficial effects: 1. This integrated phosphating and dip-coating treatment device for evaporator wire racks, by suspending a liquid receiving tray at the bottom of the transport components, can collect and receive mechanical lubricating grease and residual processing fluid dripping from the upper mechanical moving parts throughout the automated translation and lifting process of the evaporator wire rack. This effectively avoids the fluidized plastic powder from becoming damp and clumping or chemically deteriorating due to the fluid dripping into the dip-coating tank, and completely eliminates the risk of pinholes, missed spots, and subsequent rusting on the rack surface coating caused by dripping contamination. This significantly improves the surface corrosion protection quality and yield of medical equipment.

[0016] 2. This evaporator wire rack phosphate coating and plastic coating integrated treatment device, by setting a flow stabilizing component inside the liquid receiving tray, when the transport component starts, stops or changes direction suddenly, causing the liquid in the tray to surge violently due to inertia, the turbulent liquid is forcibly guided into a tortuous non-straight flow channel. By using fluid dynamics damping, large waves are broken into small eddies, and the kinetic energy of the liquid is efficiently converted into frictional consumption, ensuring that the liquid surface in the liquid receiving tray remains stable during high-speed back-and-forth movement, thereby avoiding the problem of liquid overflowing from the liquid receiving tank due to inertial shaking.

[0017] 3. This evaporator wire rack phosphate coating and plastic coating integrated treatment device, by setting anti-splash components on both sides of the liquid receiving tray, when the equipment is braked suddenly and a surge of liquid waves rolls over to both ends, the inclined force surface of the float converts the horizontal impact kinetic energy of the liquid waves and the instantaneous surge of fluid buoyancy into an upward composite thrust, so that the anti-overflow flap overcomes the torsion spring torsion and quickly flips and closes inward to the inside of the tray. After the process is completed, it automatically opens to facilitate subsequent liquid receiving. Through this adaptive dynamic anti-overflow, the wave head is intercepted in the liquid receiving tray, further ensuring the safety and cleanliness of the processing environment below.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0022] Reference Figures 1-8 An integrated phosphating and dip coating treatment device for evaporator wire racks includes a dip coating tank 11 and a phosphating tank 12. A heating channel 13 is provided between the dip coating tank 11 and the phosphating tank 12. A transport component is provided above the dip coating tank 11. A liquid receiving tray 41 is provided at the bottom of the transport component. A flow stabilizing component is provided inside the liquid receiving tray 41. Anti-splash components are provided on both sides of the liquid receiving tray 41. The liquid receiving tray 41 is located directly below the transport component to collect lubricating fluid and processing fluid dripping from the mechanical moving parts above throughout the process.

[0023] Reference Figures 1-2The transport component includes a lead screw 21 positioned above the dip coating tank 11. An external drive motor is connected to the end of the lead screw 21 to provide rotational power. A nut slider 22 is threaded onto the surface of the lead screw 21. A guide rod is positioned above the lead screw 21. A transverse groove adapted to the guide rod is opened at the top of the nut slider 22. The transverse groove and the guide rod cooperate to form a sliding limit, so as to ensure that the nut slider 22 moves smoothly in a horizontal linear motion along the axial direction of the lead screw 21.

[0024] A cylinder 23 is installed at the bottom of the nut slider 22, and a support member 24 is installed at the output end of the cylinder 23. A vertical guide rail is installed on the surface of the cylinder 23, and a support guide rod 25 is provided on the top surface of the support member 24. The top of the support guide rod 25 is slidably connected to the inside of the vertical guide rail to ensure the verticality and stability of the support member 24 when it is raised and lowered by the cylinder 23.

[0025] Reference Figure 8 The bottom end of the support member 24 is equipped with a clamp 31. The output end of the clamp 31 is symmetrically provided with swing clamp arms 32. Under the control of the clamp 31, the swing clamp arms 32 can be brought together inward to clamp or opened outward to securely hold the evaporator wire rack. The middle part of the swing clamp arm 32 is provided with a drain groove 33. The drain groove 33 is open from top to bottom to allow the residual liquid attached to the clamp arm to flow back and drain quickly.

[0026] Reference Figures 2-4 The flow stabilizing component includes a wave-damping plate 43 installed inside the liquid receiving tray 41. Inclined portions 44 are provided on both sides of the wave-damping plate 43. Through holes 45 are opened inside the wave-damping plate 43. Energy dissipation grooves 42 are opened on the bottom wall of the liquid receiving tray 41. The energy dissipation grooves 42 are wavy, forming a bottom surface structure with high and low undulations, which is used to initially disrupt the overall kinetic energy of the liquid flow when the liquid flow surges.

[0027] The wave-damping plates 43 are arranged alternately along the length of the liquid receiving tray 41. The shape of the wave-damping plates 43 is set as an isosceles trapezoid with the lower base longer than the upper base. The adjacent wave-damping plates 43 are arranged alternately to form a tortuous flow channel, which forces the originally straight liquid flow to be dispersed.

[0028] Reference Figures 5-7 The top of both ends of the liquid receiving tray 41 is equipped with a hinge rod 501. The surface of the hinge rod 501 is rotatably connected to an anti-overflow flap 502. A torsion spring 503 is connected between the hinge rod 501 and the anti-overflow flap 502. The torsion spring 503 provides elastic restoring force under normal conditions to keep the anti-overflow flap 502 in the liquid receiving open state. Limiting blocks 504 are installed at both ends of the liquid receiving tray 41. The end face of the anti-overflow flap 502 is in contact with the limiting block 504.

[0029] The liquid receiving tray 41 has a sliding groove in the middle of both ends, and the top of the sliding groove extends through the top of the liquid receiving tray 41. A sliding plate 505 is slidably connected inside the sliding groove of the liquid receiving tray 41. A friction strip is provided at the top of the sliding plate 505. Limiting grooves 506 are provided at both ends of the sliding plate 505. Limiting pins 507 that match the limiting grooves 506 are installed on the side wall of the liquid receiving tray 41 in the sliding groove. The limiting grooves 506 and the limiting pins 507 cooperate to ensure accurate sliding trajectory and prevent the sliding plate 505 from disengaging from the liquid receiving tray 41. The top of the sliding plate 505 is slidably connected to the bottom surface of the anti-overflow flap 502. The friction strip is tightly fitted to the bottom of the anti-overflow flap 502 to push the anti-overflow flap 502 to overcome torque and rotate during sliding by friction.

[0030] Vertical guide rods 508 are installed on both sides of the bottom wall of the liquid receiving tray 41. A float 509 is slidably connected to the bottom of the surface of the vertical guide rod 508. The float 509 is a lightweight hollow structure to generate increased buoyancy instantly when liquid waves surge in. The float 509 is set as a right trapezoid with the upper bottom side longer than the lower bottom side. The hypotenuse of the float 509 faces the middle of the liquid receiving tray 41. The hypotenuse serves as the force-bearing surface to convert the horizontal impact kinetic energy of the liquid waves into an upward composite thrust. A pull rope 510 is connected to the top of the vertical guide rod 508. The pull rope 510 is used to determine the initial position of the driven block 511 and can adjust the initial position of the driven block 511 according to the length of the pull rope 510. The driven block 511 is slidably connected to the top of the surface of the vertical guide rod 508. The bottom end of the pull rope 510 is connected to the surface of the driven block 511. The top of the float 509 is adapted to contact the driven block 511.

[0031] A telescopic rod 512 is rotatably connected to the surface of the driven block 511. The other end of the telescopic rod 512 is rotatably connected to the inside of the sliding plate 505. A buffer spring 513 is provided inside the telescopic rod 512. The buffer spring 513 is used to absorb rigid impact when the telescopic rod 512 transmits upward thrust.

[0032] In this invention, when the evaporator wire rack is subjected to integrated phosphating and dip coating treatment, the system starts the transport assembly set above the dip coating tank 11 and the phosphating tank 12; the external drive motor drives the lead screw 21 to rotate, and the nut slider 22, driven by the thread of the lead screw 21, moves smoothly horizontally and linearly along the axial direction of the lead screw 21 in conjunction with the sliding limit of the top transverse groove and the guide rod.

[0033] When the device moves to the feeding station or directly above each treatment tank, the cylinder 23 fixed to the bottom of the nut slider 22 is activated, and its output end pushes the support 24 downward. The support guide rod 25 slides in the vertical guide rail to ensure the verticality and stability of the descent process. Subsequently, the clamp 31 fixed to the bottom of the support 24 controls the swing clamp arms 32 symmetrically arranged on both sides of its output end to converge inward, thereby firmly clamping the evaporator wire rack. After clamping, the cylinder 23 retracts, causing the rack to rise. The nut slider 22 continues to move horizontally, and the rack is sent into the phosphating tank 12 for pretreatment according to the process sequence. Then, it is dried and preheated through the heating channel 13, and finally sent into the dip coating tank 11 to complete the surface dip coating. During the process of lifting the rack out of the liquid tank, the drain groove 33 opened in the middle of the swing clamp arm 32 can make the residual liquid attached to the clamp arm quickly flow back and drain, avoiding cross-contamination caused by liquid.

[0034] During the continuous conveying process described above, to avoid contamination, a liquid receiving tray 41 located at the bottom of the conveying component collects the dripping liquid throughout the process. When the nut slider 22 suddenly starts, stops, or reverses direction on the screw 21, the liquid in the receiving tray 41 will violently shake due to inertia. At this time, the flow stabilizing component inside the receiving tray 41 comes into play. The surging liquid flow initially disrupts the overall kinetic energy of the liquid flow in the wave-shaped energy dissipation tank 42 by utilizing the undulating bottom structure. Subsequently, the surging waves impact the wave-damping plates 43, which are arranged alternately along the length of the receiving tray 41. Because adjacent wave-damping plates 43 are staggered, the originally straight liquid flow is forcibly dispersed. The liquid is guided into a tortuous flow channel. During the process of the liquid flow shuttling and impacting the wave-damping plate 43, some of the liquid is guided through the inclined parts 44 on both sides of the wave-damping plate 43, while the other part of the liquid is forcibly squeezed into the through holes 45 opened inside the wave-damping plate 43. Through the throttling and jetting effect of the micro-holes, the large waves are broken into small eddies. In this way, the kinetic energy of the liquid is converted into heat energy and frictional consumption by using fluid dynamics damping, ensuring that the liquid surface of the receiving tray 41 remains stable during high-speed movement and preventing liquid from spilling out.

[0035] Simultaneously, when the equipment brakes suddenly, causing a surge of liquid waves inside the receiving tray 41 that tumble towards both ends, the liquid waves rushing towards both ends directly impact the float 509, which is slidably connected to the bottom of the vertical guide rod 508. Since the inclined side of the float 509 faces the middle of the receiving tray 41, the horizontal impact kinetic energy of the liquid waves and the instantaneously increased buoyancy generate a combined thrust, forcing the float 509 to rise rapidly along the vertical guide rod 508. The top of the float 509 then pushes the driven block 511 upward. Guided by the movement of the vertical guide rod 508, the driven block 511 transmits the thrust outward through the telescopic rod 512, which is rotatably connected to its surface. The buffer spring 513 inside the telescopic rod 512 absorbs the rigid impact while transmitting power. This thrust drives the sliding plate 505 in the groove in the middle of the receiving tray 41. The sliding plate 505 slides from the inside out. The limiting grooves 506 at both ends of the sliding plate 505 cooperate with the limiting pins 507 on the side wall of the chute to ensure the accuracy of its sliding trajectory and prevent the sliding plate 505 from moving away from the liquid receiving tray 41. At the moment the sliding plate 505 slides, the friction strip set at its top edge slides tightly against the bottom surface of the anti-overflow flap 502. At this time, the anti-overflow flap 502 is pushed to rotate by friction. At this time, the anti-overflow flap 502 will overcome the torsion of the torsion spring 503 and quickly flip and close inward to the liquid receiving tray 41, blocking the wave that is about to overflow into the tray. When the inertial liquid wave subsides, the float 509 falls back due to gravity. The elastic restoring force of the torsion spring 503 drives the anti-overflow flap 502 to rotate in the opposite direction and reset until its end face is re-attached to the limiting block 504, restoring the normal liquid receiving open state.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
