Description

Technical Field

[0001] The invention relates to the technical field of fan filter production and processing, and in particular to a frame material plating device and method for a fan filter unit. Background Art

[0002] The fan filter unit is an air purification device composed of a fan, a high-efficiency air filter, a cabinet and a control unit. It has certain modular dimensions and standard specifications. Usually, multiple units are used in combination and installed using standard ceiling keels. During actual production, the frame material of the fan filter unit needs to be zinc-plated on the surface due to production requirements such as aesthetics and rust prevention.

[0003] In the prior art, the frame material of the fan filter unit is usually coated with zinc on the surface by cold galvanizing, which is also called electro-galvanizing. In actual practice, the frame material that has been degreased and pickled needs to be placed in a solution containing zinc salts and connected to the negative pole of the electrolytic equipment. A zinc plate is placed opposite the frame material and connected to the positive pole of the electrolytic equipment and the power is turned on. The zinc coating is completed on the frame material by the directional movement of the current from the positive pole to the negative pole.

[0004] However, after actual application by technicians in this field, it was found that the cold galvanizing method for the fan filter unit frame material still has some disadvantages. The most obvious one is that when the frame material in the galvanizing liquid is output and transferred after the zinc layer is coated, the galvanizing liquid will remain on the surface of the frame material, so it needs to be left to stand for a period of time so that the galvanizing liquid on the surface of the frame material can be recovered under the action of gravity. This will significantly reduce the zinc coating efficiency of the frame material, which is not conducive to the industrial production of fan filters. In addition, the method of simply recycling the galvanizing liquid by gravity has an unsatisfactory recycling effect. Often, a small amount of galvanizing liquid will remain on the surface of the frame material. The loss of this part of the galvanizing liquid will not only increase the zinc coating cost, but also have an adverse effect on the subsequent processing of the frame material.

[0005] Therefore, it is necessary to invent a frame material plating device and method for a fan filter unit to solve the above problems. Summary of the invention

[0006] The object of the present invention is to provide a frame material plating device and method for a fan filter unit, which is provided with a shielding and limiting mechanism, a zinc layer plating mechanism, a driving mechanism, a bearing centrifugal mechanism and a triggering mechanism, so that the driving mechanism drives the bearing centrifugal mechanism to move downward to the inside of the zinc layer plating mechanism to complete the zinc layer plating of the frame material, and then the driving mechanism drives the bearing centrifugal mechanism to move upward to the inside of the shielding and limiting mechanism, the shielding and limiting mechanism blocks and shields the bearing centrifugal mechanism, the zinc layer plating mechanism drives the triggering mechanism to rotate, and the triggering mechanism drives the bearing centrifugal mechanism to rotate to complete the centrifugal treatment of the frame material, so that the zinc plating liquid remaining on the surface of the frame material is thrown out under the action of centrifugal force, and in this process the shielding and limiting mechanism is used to block and shield the thrown zinc plating liquid The blocking mechanism is used to make the galvanizing liquid drip along the inner wall of the shielding and limiting mechanism to the inside of the zinc coating mechanism to be recovered, so as to solve the problem proposed in the above background technology that after the zinc coating is completed, when the frame material in the galvanizing liquid is output and transferred, since there will be galvanizing liquid remaining on the surface of the frame material, it is necessary to stand for a period of time so that the galvanizing liquid on the surface of the frame material can be recovered under the action of gravity, which leads to a significant reduction in the zinc coating efficiency of the frame material, which is not conducive to the industrial production of fan filters. In addition, the method of simply using gravity to recover the galvanizing liquid has the situation that the recovery effect is not ideal, and there is often a small amount of galvanizing liquid remaining on the surface of the frame material. The loss of this part of the galvanizing liquid will not only increase the cost of zinc coating, but also have an adverse effect on the subsequent processing of the frame material.

[0019] Preferably, the trigger mechanism comprises a threaded sleeve and a second gear ring;

[0020] The threaded sleeve is arranged through the right side of the top of the end plate and is rotatably connected with the end plate through a bearing. The second gear ring is arranged on the outer bottom of the threaded sleeve through an overrunning clutch and is meshed with the first gear ring.

[0021] The present invention also discloses a frame material plating method for a fan filter unit, which is implemented using the above-mentioned frame material plating device for a fan filter unit. The method specifically comprises the following steps:

[0022] S1. Place the frame material to be processed on the top of the bottom plate from the front of the top of the bottom plate, start the driving motor, and after the driving motor is started, drive the reciprocating screw to rotate. When the reciprocating screw rotates, it drives the outer sleeve guided by the outer sleeve plate and the guide rod to move downward continuously. When the outer sleeve moves downward, the inner sleeve is driven downward by the return spring, and the one-way screw is driven downward by the outer sleeve plate. When the inner sleeve moves downward, it drives the load-bearing centrifugal mechanism and the trigger mechanism to move downward as a whole. When the load-bearing centrifugal mechanism moves downward, it drives the frame material to move downward synchronously;

[0023] S2, when the downward movement distance of the outer sleeve reaches the first threshold, the bottom of the end plate fits with the top of the second limit frame, and the negative pole passes through the avoidance channel to contact the frame material, and the electrolysis equipment is started. The electrolysis equipment begins to plate the frame material with zinc through the negative pole, the positive pole, the zinc plate and the galvanizing liquid in the galvanizing liquid storage tank. In addition, due to the obstruction of the second limit frame, the end plate cannot continue to move downward. Subsequently, as the outer sleeve continues to move downward, the inner sleeve, which is also unable to move downward, compresses the reset spring, and at the same time, the outer sleeve continues to drive the one-way screw to move downward. During the downward movement of the one-way screw, the threaded sleeve is driven to rotate continuously. At this time, due to the limitation of the overrunning clutch, the second gear ring does not rotate;

[0024] S3, when the outer sleeve moves downward to the second threshold, the outer sleeve reaches the bottom of the reciprocating thread on the outside of the reciprocating screw, and then as the reciprocating screw continues to rotate, the outer sleeve moves upward and resets. When the outer sleeve moves upward to the third threshold, the compressed reset spring resets, and the zinc coating of the frame material is completed. At this time, the electrolysis equipment is shut down;

[0025] S4, when the upward movement distance of the outer sleeve reaches the fourth threshold, the outer sleeve arrives at the initial position, and then as the reciprocating screw continues to rotate, the outer sleeve continues to move upward along the reciprocating screw. During the upward movement of the outer sleeve, the load-bearing centrifugal mechanism and the trigger mechanism are driven to move upward synchronously through the return spring and the inner sleeve;

[0026] S5. When the upward movement distance of the outer sleeve reaches the fifth threshold, the top of the end plate contacts the bottom of the first limit frame, and the first limit frame forms a blockage for the end plate. At this time, the bearing centrifugal mechanism and the trigger mechanism are both located on the inner side of the shielding cover. Subsequently, as the outer sleeve continues to move upward, the inner sleeve that cannot move upward due to the end plate stretches the reset spring. At the same time, the outer sleeve drives the one-way screw to rise. During the rising process of the one-way screw, the threaded sleeve is driven to rotate. When the threaded sleeve rotates, the second gear ring and the first gear ring are used to drive the rotating column to rotate. When the rotating column rotates, the top plate, multiple connecting columns and the bottom plate are used to drive the frame material to rotate. During the rotation of the frame material, the blocking ring blocks the frame material. At the same time, the galvanizing liquid remaining on the surface of the frame material is thrown out under the action of centrifugal force. The shielding cover blocks the galvanizing liquid that is thrown out, so that the galvanizing liquid drips along the inner wall of the shielding cover into the galvanizing liquid storage tank to be recovered.

[0027] S6. When the upward movement distance of the outer sleeve reaches the sixth threshold, the outer sleeve moves to the top of the reciprocating thread on the outside of the reciprocating screw. Subsequently, as the reciprocating screw continues to rotate, the outer sleeve moves downward and resets. When the downward movement distance of the outer sleeve reaches the seventh threshold, the outer sleeve arrives at the initial position again. At this time, the drive motor is stopped, and then the frame material is removed from the top of the base plate.

[0028] Technical effects and advantages of the present invention:

[0029] The present invention is provided with a shielding and limiting mechanism, a zinc layer coating mechanism, a driving mechanism, a bearing centrifugal mechanism and a triggering mechanism, so that the driving mechanism drives the bearing centrifugal mechanism to move downward to the inside of the zinc layer coating mechanism to complete the zinc layer coating of the frame material, and then the driving mechanism drives the bearing centrifugal mechanism to move upward to the inside of the shielding and limiting mechanism, the shielding and limiting mechanism blocks and shields the bearing centrifugal mechanism, the zinc layer coating mechanism drives the triggering mechanism to rotate, and the triggering mechanism drives the bearing centrifugal mechanism to rotate to complete the centrifugal treatment of the frame material, so that the zinc plating liquid remaining on the surface of the frame material is removed under the action of centrifugal force. The zinc plating liquid is thrown out, and during this process, the shielding and limiting mechanism blocks the thrown-out zinc plating liquid, so that the zinc plating liquid drips along the inner wall of the shielding and limiting mechanism to the inside of the zinc layer coating mechanism to be recovered. Compared with the conventional cold galvanizing method in the prior art, the present invention has a high degree of automation and can more quickly recover the residual zinc plating liquid on the surface of the frame material, thereby improving the zinc coating efficiency of the frame material and being more suitable for the industrial production of fan filters. In addition, the recovery effect of the zinc plating liquid is more ideal, which reduces the zinc coating cost while avoiding the adverse effects on the subsequent processing of the frame material due to the residual zinc plating liquid.

[0041] By setting the above structure, when the bottom of the end plate 51 is in contact with the top of the second limit frame 32, the negative electrode column 34 passes through the avoidance channel 58 and contacts the frame material, and the electrolysis equipment 33 is started.

[0043] like Figure 5As shown, the centrifugal bearing mechanism 5 includes an end plate 51, a rotating column 52, a first gear ring 53, a top plate 54, a connecting column 55, a bottom plate 56, a blocking ring 57, an avoidance channel 58 and a drainage hole 59, wherein the end plate 51 is fixedly arranged at the bottom end of the inner sleeve 45, the rotating column 52 is rotatably nested and arranged at the left side of the bottom of the end plate 51 through a bearing, the first gear ring 53 is fixedly sleeved and arranged on the outside of the rotating column 52, the top plate 54 is fixedly arranged at the bottom end of the rotating column 52, a plurality of connecting columns 55 are provided, and a plurality of the connecting columns 55 are evenly fixedly arranged on the rear side of the bottom of the top plate 54, the bottom plate 56 is fixedly arranged at the bottom ends of the plurality of connecting columns 55, the blocking ring 57 is fixedly sleeved and arranged on the outside of the plurality of connecting columns 55 and fixedly arranged on the top of the bottom plate 56, the avoidance channel 58 is opened at the center of the top of the bottom plate 56, and a plurality of drainage holes 59 are provided, and a plurality of the drainage holes 59 are evenly opened on the top of the bottom plate 56.

[0044] By setting the above-mentioned driving mechanism 4 and the bearing centrifugal mechanism 5, the frame material to be processed can be placed on the top of the bottom plate 56 from the front of the top of the bottom plate 56, and the driving motor 42 is started. After the driving motor 42 is started, it drives the reciprocating screw 41 to rotate. When the reciprocating screw 41 rotates, it drives the outer sleeve 43 guided by the outer sleeve plate 46 and the guide rod 47 to move downward continuously. When the outer sleeve 43 moves downward, the inner sleeve 45 is driven downward by the return spring 44, and the one-way screw 48 is driven downward by the outer sleeve plate 46.

[0046] By providing the above-mentioned shielding and limiting mechanism 2, the bearing centrifugal mechanism 5 and the trigger mechanism 6, the threaded sleeve 61 is driven to rotate continuously during the downward movement of the one-way screw 48.

At the same time, the galvanizing liquid remaining on the surface of the frame material is thrown out under the action of centrifugal force. The shielding cover 21 blocks the galvanizing liquid that is thrown out, so that the galvanizing liquid drips along the inner wall of the shielding cover 21 into the galvanizing liquid storage tank 31 and is recovered.

[0047] The present invention also discloses a frame material plating method for a fan filter unit, which is implemented using the above-mentioned frame material plating device for a fan filter unit. The method specifically comprises the following steps:

[0048] S1. Place the frame material to be processed on the top of the bottom plate 56 from the front of the top of the bottom plate 56, start the driving motor 42, and after the driving motor 42 is started, it drives the reciprocating screw 41 to rotate. When the reciprocating screw 41 rotates, it drives the outer sleeve 43 guided by the outer sleeve plate 46 and the guide rod 47 to continuously move downward. When the outer sleeve 43 moves downward, it drives the inner sleeve 45 to move downward through the return spring 44, and drives the one-way screw 48 to move downward through the outer sleeve plate 46. When the inner sleeve 45 moves downward, it drives the bearing centrifugal mechanism 5 and the trigger mechanism 6 to move downward as a whole. When the bearing centrifugal mechanism 5 moves downward, it drives the frame material to move downward synchronously;

[0049] S2, when the downward movement distance of the outer sleeve 43 reaches the first threshold, the bottom of the end plate 51 fits with the top of the second limit frame 32, and the negative pole 34 passes through the avoidance channel 58 to contact the frame material, and the electrolysis equipment 33 is started. The electrolysis equipment 33 begins to plate the frame material with zinc through the negative pole 34, the positive pole 35, the zinc plate 36 and the zinc plating liquid inside the zinc plating liquid storage tank 31. In addition, due to the obstruction of the second limit frame 32, the end plate 51 cannot continue to move downward. Subsequently, as the outer sleeve 43 continues to move downward, the inner sleeve 45 of the end plate 51, which is also unable to move downward, compresses the reset spring 44, and at the same time, the outer sleeve 46 continues to drive the one-way screw 48 to move downward. During the downward movement of the one-way screw 48, the threaded sleeve 61 is driven to rotate continuously. At this time, due to the limitation of the overrunning clutch, the second gear ring 62 does not rotate;

[0050] S3, when the outer sleeve 43 moves downward to a second threshold, the outer sleeve 43 reaches the bottom of the reciprocating thread on the outer side of the reciprocating screw 41, and then as the reciprocating screw 41 continues to rotate, the outer sleeve 43 moves upward to reset. When the outer sleeve 43 moves upward to a third threshold, the compressed reset spring 44 resets, and the zinc coating of the frame material is completed. At this time, the electrolysis equipment 33 is shut down;

[0051] S4, when the upward movement distance of the outer sleeve 43 reaches the fourth threshold, the outer sleeve 43 arrives at the initial position, and then as the reciprocating screw 41 continues to rotate, the outer sleeve 43 continues to move upward along the reciprocating screw 41. During the upward movement of the outer sleeve 43, the return spring 44 and the inner sleeve 45 drive the centrifugal mechanism 5 and the trigger mechanism 6 to move upward synchronously;

[0052] S5, when the upward movement distance of the outer sleeve 43 reaches the fifth threshold, the top of the end plate 51 contacts the bottom of the first limit frame 22, and the first limit frame 22 blocks the end plate 51. At this time, the centrifugal mechanism 5 and the trigger mechanism 6 are both located on the inner side of the shielding cover 21. As the outer sleeve 43 continues to move upward, the inner sleeve 45, which cannot move upward due to the end plate 51, stretches the reset spring 44. At the same time, the outer sleeve 46 drives the one-way screw 48 to rise. During the one-way screw 48 rising, the threaded sleeve 61 is driven Rotate, when the threaded sleeve 61 rotates, the second gear ring 62 and the first gear ring 53 drive the rotating column 52 to rotate, and when the rotating column 52 rotates, the top plate 54, multiple connecting columns 55 and the bottom plate 56 drive the frame material to rotate. During the rotation of the frame material, the blocking ring 57 blocks the frame material, and at the same time, the galvanizing liquid remaining on the surface of the frame material is thrown out under the action of centrifugal force, and the shielding cover 21 blocks the galvanizing liquid that is thrown out, so that the galvanizing liquid drips along the inner wall of the shielding cover 21 to the inside of the galvanizing liquid storage tank 31 to be recovered;

[0053] S6. When the upward movement distance of the outer sleeve 43 reaches the sixth threshold, the outer sleeve 43 moves to the top of the reciprocating thread on the outside of the reciprocating screw 41. Subsequently, as the reciprocating screw 41 continues to rotate, the outer sleeve 43 moves downward and resets. When the downward movement distance of the outer sleeve 43 reaches the seventh threshold, the outer sleeve 43 arrives at the initial position again. At this time, the drive motor 42 is stopped, and then the frame material is removed from the top of the base plate 56.

[0054] It should also be noted that the first threshold and the second threshold increase successively, and the third threshold, the fourth threshold, the fifth threshold and the sixth threshold increase successively, and the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold, the sixth threshold and the seventh threshold are recorded for the convenience of accurately describing the actual working conditions of the scheme;

[0055] When the solution of the present application is actually produced, according to the actual specifications of the reciprocating screw 41, the first threshold value, the second threshold value, the third threshold value, the fourth threshold value, the fifth threshold value, the sixth threshold value and the seventh threshold value are all specific values.

[0056] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.

2. A method for plating a frame material of a fan filter unit, characterized in that: The method is implemented using a frame material coating device for a fan filter unit as claimed in claim 1, and the method specifically comprises the following steps: S1, placing the frame material to be processed on the top of the bottom plate (56) from the front of the top of the bottom plate (56), and starting the driving motor (42). After the driving motor (42) is started, it drives the reciprocating screw (41) to rotate. When the reciprocating screw (41) rotates, it drives the outer sleeve (43) guided by the outer sleeve plate (46) and the guide rod (47) to continuously move downward. When the outer sleeve (43) moves downward, it drives the inner sleeve (45) to move downward through the return spring (44), and drives the one-way screw (48) to move downward through the outer sleeve plate (46). When the inner sleeve (45) moves downward, it drives the load-bearing centrifugal mechanism (5) and the trigger mechanism (6) to move downward as a whole. When the load-bearing centrifugal mechanism (5) moves downward, it drives the frame material to move downward synchronously; S2, when the downward movement distance of the outer sleeve (43) reaches the first threshold, the bottom of the end plate (51) fits with the top of the second limit frame (32), and the negative pole (34) passes through the avoidance channel (58) and contacts the frame material, and the electrolysis device (33) is started. The electrolysis device (33) begins to plate the frame material with zinc through the negative pole (34), the positive pole (35), the zinc plate (36) and the zinc plating liquid in the zinc plating liquid storage tank (31). In addition, due to the obstruction of the second limit frame (32), the end plate (51) cannot move downward further. Subsequently, as the outer sleeve (43) continues to move downward, the inner sleeve (45) of the end plate (51) which is also unable to move downward compresses the reset spring (44), and at the same time, the outer sleeve (46) continues to drive the one-way screw (48) to move downward. During the downward movement of the one-way screw (48), the threaded sleeve (61) is driven to rotate continuously. At this time, due to the limitation of the overrunning clutch, the second gear ring (62) does not rotate; S3, when the downward movement distance of the outer sleeve (43) reaches the second threshold value, the outer sleeve (43) reaches the bottom end of the reciprocating thread on the outer side of the reciprocating screw (41), and then as the reciprocating screw (41) continues to rotate, the outer sleeve (43) moves upward and resets. When the upward movement distance of the outer sleeve (43) reaches the third threshold value, the compressed reset spring (44) resets, and the zinc coating of the frame material is completed. At this time, the electrolysis equipment (33) is shut down; S4, when the upward movement distance of the outer sleeve (43) reaches the fourth threshold value, the outer sleeve (43) arrives at the initial position, and subsequently, as the reciprocating screw (41) continues to rotate, the outer sleeve (43) continues to move upward along the reciprocating screw (41). During the upward movement of the outer sleeve (43), the load-bearing centrifugal mechanism (5) and the trigger mechanism (6) are driven to move upward synchronously through the return spring (44) and the inner sleeve (45); S5. When the upward movement distance of the outer sleeve (43) reaches the fifth threshold value, the top of the end plate (51) contacts the bottom of the first limit frame (22), and the first limit frame (22) blocks the end plate (51). At this time, the centrifugal mechanism (5) and the trigger mechanism (6) are both located on the inner side of the shielding cover (21). Subsequently, as the outer sleeve (43) continues to move upward, the inner sleeve (45) that cannot move upward due to the end plate (51) stretches the return spring (44), and at the same time, the outer sleeve (46) drives the one-way screw (48) to rise. During the process of the one-way screw (48) rising, the threaded sleeve is driven (61) rotates, and when the threaded sleeve (61) rotates, the second gear ring (62) and the first gear ring (53) drive the rotating column (52) to rotate. When the rotating column (52) rotates, the top plate (54), the plurality of connecting columns (55) and the bottom plate (56) drive the frame material to rotate. During the rotation of the frame material, the blocking ring (57) blocks the frame material, and at the same time, the galvanizing liquid remaining on the surface of the frame material is thrown out under the action of centrifugal force. The shielding cover (21) blocks the galvanizing liquid that is thrown out, so that the galvanizing liquid drips along the inner wall of the shielding cover (21) into the galvanizing liquid storage tank (31) to be recovered; S6. When the upward movement distance of the outer sleeve (43) reaches the sixth threshold value, the outer sleeve (43) moves to the top of the reciprocating thread on the outside of the reciprocating screw (41). Subsequently, as the reciprocating screw (41) continues to rotate, the outer sleeve (43) moves downward and resets. When the downward movement distance of the outer sleeve (43) reaches the seventh threshold value, the outer sleeve (43) arrives at the initial position again. At this time, the drive motor (42) is stopped, and then the frame material is removed from the top of the bottom plate (56).
