Description

Technical Field

[0001] This invention relates to the field of dyeing apparatus, and in particular to an apparatus for dyeing anti-radiation resin eyeglass lenses. Background Technology

[0002] Chinese Patent No. CN205982693U discloses a lens dyeing device, including a dye pool, an electrical control box, a suspension device, and a fan. The electrical control box is located above the dye pool and contains an electric push rod that drives the suspension device to move up and down. The suspension device and the fan are located between the electrical control box and the dye pool. The suspension device includes a base plate, a suspension assembly, a power assembly, and a guide assembly. The upper side of the base plate is connected to the electric push rod, and the lower side is provided with a fixing plate. The suspension assembly includes a connecting plate, a connecting block, and a set of hooks. The connecting block is located on the connecting plate. The power assembly includes a motor, a turntable, a first connecting shaft, a second connecting shaft, and a connecting rod. The first connecting shaft is located near the edge of the turntable, and the second connecting shaft is located on the connecting block. The two ends of the connecting rod are respectively movably sleeved on the first and second connecting shafts.

[0003] During lens dyeing, the electric push rod pushes the substrate downward. As the substrate moves downward, the power component drives the suspension component to move up and down repeatedly, causing multiple sets of lenses suspended on the suspension component to be repeatedly immersed in the dye bath, thereby improving the dyeing quality of the lenses. Each set of lenses carries away the original dye bath during dyeing, causing the dye bath liquid level to drop. However, the movement path of each set of lenses is fixed. In order to ensure that the lenses are completely immersed in the dye bath during dyeing, it is necessary to manually add dye to the dye bath continuously to ensure that the dye bath liquid level meets the lens dyeing requirements. This results in a lack of automation. Summary of the Invention

[0004] This application provides a device for dyeing anti-radiation resin eyeglass lenses, which has the effect of automatically adding dye solution to the soaking tank.

[0005] The anti-radiation resin eyeglass lens dyeing device provided in this application adopts the following technical solution:

[0006] A device for dyeing anti-radiation resin eyeglass lenses includes a body. The body has a tabletop with a dye bath and a clean water bath for storing dye solution. The body has a fixed plate, a hydraulic cylinder for driving the fixed plate up and down, a shelf slidably connected to the fixed plate in a vertical direction, a mounting block on the fixed plate, and a drive unit on the mounting block. The drive unit drives the shelf to reciprocate up and down. The dye bath contains an immersion tank for dyeing the lenses. The body has a supply channel connecting the dye bath and the immersion tank. The bottom wall of the dye bath has an inlet channel connecting to the supply channel. The inlet channel contains a first one-way valve allowing only dye solution to enter the supply channel from the inlet channel. The supply channel also contains a second one-way valve allowing only dye solution to enter the immersion tank from the supply channel. A piston is slidably connected in the supply channel in a vertical direction. The body has a drive mechanism for driving the piston to reciprocate in a vertical direction. The connection between the inlet channel and the supply channel is located below the piston's sliding path.

[0007] By adopting the above technical solution, after each new lens assembly is immersed in the soaking tank, the piston is driven by the drive mechanism to slide downward in the liquid supply channel. During the downward sliding process, the piston will squeeze the dye liquid in the liquid supply channel into the soaking tank to replenish the dye liquid in the soaking tank. Then, the drive mechanism will drive the piston to slide upward in the liquid supply channel to reset. During the upward sliding process, the piston will draw the dye liquid in the dyeing tank into the liquid supply channel through the liquid inlet channel to prepare for the next supply of dye liquid to the soaking tank.

[0008] Preferably, the drive mechanism includes a first rack disposed on the piston and a drive assembly for driving the first rack to reciprocate in a vertical direction.

[0009] By adopting the above technical solution, a drive assembly is used to drive the first rack to reciprocate in the vertical direction, thereby driving the piston to slide up and down in the liquid supply channel.

[0010] Preferably, the drive assembly includes a fixed box mounted on the machine body, a gear rotatably connected inside the fixed box, and a second rack meshing with the gear. The end of the second rack away from the gear is fixed to the output shaft of the hydraulic cylinder. The first rack has several tooth grooves, and the top end of the first rack extends into the fixed box and meshes with the gear.

[0011] By adopting the above technical solution, when the lenses need to be dyed, the lens assembly is suspended on the shelf, and then the dyeing device is started. The output shaft of the hydraulic cylinder extends, driving the shelf downwards so that the lens assembly is immersed in the dyeing solution in the soaking tank. During the extension of the output shaft of the hydraulic cylinder, the second rack also moves downwards and drives the gear to rotate. The rotation of the gear drives the first rack to rise, which in turn drives the piston to rise, thereby drawing the dye solution in the dyeing tank into the supply channel through the inlet channel. After the lens assembly is soaked, the output shaft of the hydraulic cylinder retracts, causing the shelf to rise and moving the lens assembly away from the dyeing tank. When the output shaft of the hydraulic cylinder retracts, it drives the second rack to move upwards. During the upward movement of the second rack, the connecting rod moves downwards through the gear. During the downward movement of the connecting rod, the piston slides downwards, squeezing the dye solution in the supply channel into the soaking tank to replenish the dye solution in the soaking tank.

[0012] Preferably, the bottom wall of the dye bath is recessed to form a liquid collection cavity, and the liquid inlet channel connects the liquid collection cavity and the liquid supply channel.

[0013] By adopting the above technical solution, a liquid collection chamber is set up to assist in guiding the dye liquor into the supply channel through the inlet channel, thereby reducing the probability that the dye liquor cannot flow into the supply channel in time when the liquid level in the dye liquor tank is low.

[0014] Preferably, the lowest point of the liquid supply channel is provided with a drain channel that communicates with the outside. A sealing cover for sealing the drain channel is slidably connected inside the drain channel. A connecting rod is provided on the sealing cover. A sliding groove is provided on the top wall of the liquid supply channel. The connecting rod is slidably connected in the sliding groove. A control mechanism is provided on the machine body. The control mechanism is used to control the sliding of the connecting rod.

[0015] By adopting the above technical solution, when it is necessary to replace the old dye solution to dye the lens, the connecting rod control mechanism controls the connecting rod to slide upward so that the sealing cover slides into the liquid supply channel and no longer blocks the drain channel. Then, the driving mechanism drives the piston to move, which can squeeze the old dye solution in the dye pool and the feeding channel into the drain channel and discharge it together into the machine body.

[0016] Preferably, the control mechanism includes a spring sleeved on a connecting rod, a pressure plate located at the top of the connecting rod, and a pressure block located on the machine body. An installation groove is provided on the bottom wall of the soaking tank, and the liquid supply channel communicates with the installation groove. The pressure block is detachably connected to the installation groove. The second one-way valve is located inside the pressure block. A sliding groove is provided on the side wall of the liquid supply channel above the drainage channel. One end of the pressure plate, away from the connecting rod, extends into the installation groove through the communicating groove. A locking groove for the pressure plate to engage is provided on the bottom surface of the pressure block. A receiving cavity for accommodating the spring is provided on the side wall of the sliding groove. One end of the spring abuts against the bottom wall of the receiving cavity, and the other end abuts against the bottom wall of the pressure plate. The spring is always in a compressed state.

[0017] By adopting the above technical solution, when it is necessary to replace the lens with a new dye solution, the pressure block is removed from the mounting slot. When the pressure block is removed, it will cause the pressure plate to move upward, and the spring will also rebound, causing the pressure plate to move upward. When the pressure plate moves upward, it will cause the connecting rod to move upward, so that the sealing cover slides away from the drain channel. Finally, the pressure block and the second one-way valve will be removed from the mounting slot. At the same time, the pressure plate will be removed from the slot and pressed against the top wall of the connecting slot by the spring. At this time, the sealing cover enters the supply channel and no longer blocks the drain channel. The old liquid in the soaking tank can also flow into the drain channel along the supply channel and finally be discharged from the machine.

[0018] Preferably, the bottom of the sealing cap is provided with a drainage plate, and the end of the drainage plate away from the sealing cap is always located in the drainage channel.

[0019] By adopting the above technical solution, when the sealing cover is no longer blocking the drainage channel, the old liquid in the soaking tank and the dyeing liquid tank will flow together toward the drainage channel. By setting up a diversion plate, the old liquid can be guided into the drainage channel, and the impact of the collision between the old liquid in the two tanks above the drainage channel on the old liquid discharge speed can be reduced, thereby ensuring the efficiency of old liquid discharge and avoiding wasting too much time on cleaning the old liquid during production.

[0020] Preferably, an avoidance groove is provided on the bottom wall of the connecting groove, and a water baffle is fixedly connected to the bottom of the pressure plate. The water baffle slides vertically and is connected in the avoidance groove.

[0021] By adopting the above technical solution, when the pressure plate is raised, it will cause the baffle plate to slide out of the clearance groove, thereby blocking the connecting groove and reducing the probability of old liquid entering the connecting groove when the soaking tank is drained.

[0022] The main technical effects of this invention are reflected in the following aspects:

[0023] 1. This invention utilizes the extension and retraction of the hydraulic cylinder output shaft to achieve piston sliding, thereby delivering the dye solution into the soaking tank;

[0024] 2. This invention enables the discharge of waste liquid from the dyeing tank after the pressure block is removed from the installation groove;

[0025] 3. When cleaning old dye liquor, the piston can also help clean the dye liquor and assist in cleaning the dye liquor tank and the immersion tank. Attached Figure Description

The two ends of the hinge rod 625 are respectively hinged to the first connecting shaft 623 and the second connecting shaft 624. The shelf 63 is located directly above the soaking pool 12.

[0033] Reference Figure 1 and Figure 2 An installation groove 18 is provided on the bottom wall of the soaking tank 12. A liquid supply channel 13 is also provided on the body 1, which connects the dyeing liquid tank 11 and the installation groove 18. A liquid collection chamber 15 is formed by a recess in the bottom wall of the dyeing liquid tank 11. An inlet channel 14 is provided on the bottom wall of the liquid collection chamber 15, which connects to the liquid supply channel 13. A first one-way valve 21 is fixedly connected in the inlet channel 14, which only allows the dyeing liquid to enter the liquid supply channel 13 from the inlet channel 14.

[0034] Reference Figure 1 and Figure 2 The lowest point of the liquid supply channel 13 is provided with a drain channel 16 that connects to the outside. A sealing cover 81 for sealing the drain channel 16 is slidably connected in the vertical direction inside the drain channel 16. A connecting rod 82 is fixedly connected to the top of the sealing cover 81 and a drainage plate 83 is fixedly connected to the bottom.

[0035] Reference Figure 1 and Figure 2The body 1 is also equipped with a control mechanism 9, which is used to control the sliding of the connecting rod 82. The control mechanism 9 includes a spring 91 sleeved on the connecting rod 82, a pressure plate 92 fixed to the top of the connecting rod 82, and a pressure block 93 detachably connected to the mounting groove 18 by bolts. A second one-way valve 23 is installed inside the pressure block 93. A connecting groove 19 is opened on the side wall of the mounting groove 18 near the slide groove 17, and the end of the pressure plate 92 away from the connecting rod 82 extends into the mounting groove 18 through the connecting groove 19. A locking groove 931 for the pressure plate 92 to be engaged is opened on the bottom surface of the pressure block 93. A receiving cavity 171 for accommodating the spring 91 is opened on the side wall of the slide groove 17. One end of the spring 91 abuts against the bottom wall of the receiving cavity 171 and the other end abuts against the bottom wall of the pressure plate 92. The spring 91 is always in a compressed state. When the pressure block 93 is bolted into the mounting groove 18, the second one-way valve 23 connects to the liquid supply channel 13, allowing the dye solution to enter the soaking tank 12 only through the liquid supply channel 13. Simultaneously, the pressure plate 92 is locked in the groove 931 and pressed against the bottom wall of the connecting groove 19 by the pressure block 93, while the sealing cap 81 is located in the drain channel 16 and seals the drain channel 16. A clearance groove 20 is vertically formed on the bottom wall of the connecting groove 19 near the liquid supply channel 13. A baffle plate 10 is fixedly connected to the bottom of the end of the pressure plate 92 away from the connecting rod 82, and the baffle plate 10 slides vertically within the clearance groove 20.

[0036] Reference Figure 1 and Figure 3 A piston 22 is slidably connected vertically within a supply channel 13 located below the dye bath 11. The connection port between the inlet channel 14 and the supply channel 13 is located below the sliding path of the piston 22. The machine body 1 is equipped with a drive mechanism 7 for driving the piston 22 to reciprocate vertically. A liquid-proof pipe is fixedly connected to the outlet of the supply channel 13, which connects to the dye bath 11. The bottom end of the liquid-proof pipe connects to the supply channel 13, while the top end extends out of the dye bath 11. The drive mechanism 7 includes a first rack 71 fixedly connected to the piston 22, which slides vertically within the liquid-proof pipe.

[0037] Reference Figure 1 and Figure 3 The drive unit also includes a drive assembly 72 for driving the first rack 71 to reciprocate vertically. The drive assembly 72 includes a fixed housing 721 fixed to the body 1, a gear 722 rotatably connected to the fixed housing 721 in the horizontal direction, and a second rack 723 meshing with the gear 722. A fixed rod is fixedly connected to the top of the second rack 723, and the end of the fixed rod away from the second rack 723 is fixedly connected to the output shaft of one of the hydraulic cylinders 5. The top of the first rack 71 extends into the fixed housing 721 and meshes with the gear 722. The first rack 71 and the second rack 723 are arranged opposite each other on both sides of the gear 722, and their movement direction is vertical.

[0038] The specific usage steps of this embodiment are as follows:

[0039] When the lenses need to be dyed, the lens assembly is suspended on the shelf 63, and then the dyeing device is started. The output shaft of the oil cylinder 5 extends, thereby driving the fixed plate 4 to move downward. During the downward movement of the fixed plate 4, the motor 621 drives the turntable 622 and the first connecting shaft 623 to rotate. When the first connecting shaft 623 rotates, it drives the shelf 63 to move up and down through the hinge rod 625 and the second connecting shaft 624, so that the lens assembly on the shelf 63 is continuously immersed in the dye solution in the soaking tank 12, resulting in a good dyeing effect for the lenses.

[0040] During the extension of the output shaft of the hydraulic cylinder 5, the second rack 723 will also move down and drive the gear 722 to rotate. The rotation of the gear 722 will drive the first rack 71 to rise, thereby driving the piston 22 to rise, so that the dye liquid in the dye bath 11 is drawn into the supply channel 13 through the inlet channel 14.

[0041] After the lens assembly is soaked, the output shaft of the hydraulic cylinder 5 retracts, causing the shelf 63 to rise and move the lens assembly away from the dyeing tank. Then, the lens assembly is removed and placed in the clean water tank 3 to remove excess dye that has not yet solidified from the surface. When the output shaft of the hydraulic cylinder 5 retracts, it will drive the second rack 723 to move upward. During the upward movement of the second rack 723, it will drive the first rack 71 to move downward through the gear 722. During the downward movement of the first rack 71, it will drive the piston 22 to slide downward. During the downward movement of the piston 22, it will squeeze the dye in the liquid supply channel 13 into the soaking tank 12 to replenish the dye in the soaking tank 12.

[0042] When the lens needs to be dyed again, the bolts are removed and the pressure block 93 is taken out of the mounting slot 18. When the pressure block 93 is taken out, it will drive the pressure plate 92 and the baffle plate 10 to move upward. At the same time, the spring 91 will also rebound and drive the pressure plate 92 to move upward. When the pressure plate 92 moves upward, it will drive the connecting rod 82 to move upward, so that the sealing cover 81 slides away from the drain channel 16. Finally, the pressure block 93, together with the second one-way valve 23, will be removed from the mounting slot 18, and the pressure plate 92 will be removed from the slot 931 and pressed against the top wall of the connecting slot 19 by the spring 91. At this time, the baffle plate 10 slides out of the clearance slot 20 and seals the slot of the connecting slot 19. The bottom end of the baffle plate 10 is still in the clearance slot 20, while the sealing cover 81 slides into the supply channel 13 and no longer seals the drain channel 16. The old liquid in the soaking tank 12 and the old liquid in the dyeing tank 11 can also flow into the drain channel 16 along the supply channel 13. During the drainage process, the operator can start the dyeing device and use the movement of piston 22 to assist in the drainage of the old dye solution.

[0043] After the drainage is completed, align the slot 931 on the pressure block 93 with the pressure plate 92 and then press the pressure block 93 into the mounting groove 18. During the process of the pressure block 93 entering the mounting groove 18, the pressure block 93 will move downward with the pressure plate 92, the connecting rod 82, and the sealing cover 81. Finally, the pressure block 93 is completely located in the receiving groove. At this time, the pressure plate 92 is inserted into the slot 931 and pressed against the bottom wall of the connecting groove 19 by the pressure block 93, while the sealing cover 81 slides into the drainage channel 16 and seals the drainage channel 16. The second one-way valve 23 connects to the liquid supply channel 13. Then, the pressure block 93 is fixed in the mounting groove 18 by bolts.

[0044] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
