Description

Technical Field

[0001] The invention relates to the technical field of optical coating material preparation equipment, and in particular to a uniform mixing device for optical coating materials. Background Art

[0002] Optical coating materials are one or more layers of films coated on the surface of optical parts to change the surface characteristics of optical parts. These films can be metal films, dielectric films or a combination of these two types of films. Optical coating materials involve thin and uniform dielectric film layers attached to the surface of optical devices during the propagation path of light. The reflection, transmission (refraction) and polarization characteristics of the layered dielectric film layers are used to achieve special forms of light such as full transmission, full reflection or polarization separation of light within a certain or multiple wavelength bands.

[0003] For example, in the preparation process of optical coating color powder, the raw materials need to be crushed and ground first, and then the ground raw materials are mixed with solvents (such as water or organic solvents), dispersants, surfactants and other additives. Then, the completely stirred slurry is dried, ground, air-selected and other processes are carried out before the optical coating color powder can be produced.

[0004] During the grinding of the ground raw materials and other additives, since various materials are directly poured into the mixing container in the initial stage of stirring, it is easy to cause the raw material particles to adsorb each other due to differences in physical properties or incompatibility of their components, thereby forming agglomerates. The outer layer of these agglomerates will block the further mixing of the internal raw material particles with the solvent or additives, and the agglomeration of large particles will affect the coating quality and may also cause defects in the coating process, such as bubbles, cracks, etc., thereby affecting the performance and life of the optical device.

[0005] In view of this, this application is hereby filed. Summary of the invention

[0022] See also Figure 1-4 The present invention provides a technical solution: a winding roller 23 is sleeved on the outer side of the outer arc wall of the driving shaft 13 located at one end of the sleeve shaft 12, a fixing clamp 24 is fixedly connected to the outer arc wall of the winding roller 23, a radially penetrating channel 1 is opened on the outer arc wall of the sleeve shaft 12 at a position corresponding to the fixing clamp 24, the winding roller 23 is rotatably connected to the inner arc wall of the sleeve shaft 12, one end of the fixing clamp 24 away from the winding roller 23 is arranged toward the channel 1, and one end of the fixed pull rope 22 away from the scraper 21 is arranged to pass through the channel 1 and is fixedly connected to the fixing clamp 24.

[0023] It should be noted that: the fixing clamp 24 is used to fix the fixed pull rope 22, and the winding roller 23 is rotatably connected to the inner arc wall of the sleeve shaft 12. Then, when the top column 31 is inserted into the groove 2, the winding roller 23 will rotate synchronously with the drive shaft 13, and then the winding roller 23 will drive the fixing clamp 24 to pull the fixed pull rope 22, and then drive the scraper 21 to scrape the stirring filter plate 20.

[0024] See also Figure 1-4The present invention provides a technical solution: a channel 2 is provided at the center of a side wall of the fixing clamp 24 away from the winding roller 23, and the channel 2 penetrates radially along the sleeve shaft 12; a groove 1 is provided on the outer arc wall of the winding roller 23 at a position corresponding to the fixing clamp 24; the fixing clamp 24 is fixedly connected in the groove 1; a top column 31 is slidably connected to the side of the groove 1 away from the fixing clamp 24; a groove 2 is provided on the outer arc wall of the driving shaft 13 at a position corresponding to the top column 31; the top column 31 is adapted to the groove 2.

[0025] It should be noted that in a possible embodiment, the longitudinal section of the fixing clamp 24 is in the shape of a "door", and the opening is arranged toward channel one, and channel two is arranged in both ends close to channel one, and the fixing pull rope 22 is fixed in the opening of the fixing clamp 24.

[0026] See also Figure 1-4 The present invention provides a technical solution: the channel 2 on the fixing clamp 24 is interconnected with the groove 1, a slide rod 30 is slidably connected in the channel 2, one end of the slide rod 30 away from the winding roller 23 passes through the channel 1 and is located outside the sleeve shaft 12, and a rotating plate 32 is provided in the groove 1 at a position of one end of the slide rod 30 close to the driving shaft 13, the rotating plate 32 is rotatably connected to the inner side wall of the groove 1, and the axial direction of the rotating axis of the rotating plate 32 is perpendicular to the axial direction of the driving shaft 13.

[0027] It should be noted that: the cross section of the end of the slide bar 30 away from the winding roller 23 is larger, the cross-sectional area of ​​the slide bar 30 is smaller than the surface area of ​​the contact area between the scraper 21 and the slide bar 30, and the side wall of the slide bar 30 facing the stirring rotation direction is an inclined surface, which allows the slide bar 30 to have sufficient contact time with the scraper 21 and the inclined surface of the slide bar 30 facilitates the scraper 21 to apply limiting pressure to the slide bar 30 after the slide bar 30 contacts the scraper 21; When the scraper 21 is pulled until it abuts against the end of the slide rod 30, the slide rod 30 is squeezed and contracted to push the rotating plate 32 to rotate, and the rotating plate 32 pushes the top column 31 to move toward the side away from the groove 2, so that the winding roller 23 no longer rotates synchronously with the drive shaft 13.

[0028] See also Figure 1-4 The present invention provides a technical solution: one end of the rotating plate 32 is in contact with the sliding rod 30, and the end of the rotating plate 32 away from the sliding rod 30 is in contact with the top column 31, and a fixing ring is fixedly connected to the side of the outer arc wall of the top column 31 away from the driving shaft 13, and the fixing ring and the rotating plate 32 are in contact with each other, and a spring telescopic rod is fixedly connected to the side wall of the top column 31 away from the driving shaft 13, and one end of the spring telescopic rod away from the top column 31 is fixedly connected to the fixing clamp 24, and a reset spring is sleeved on the end of the outer arc wall of the sliding rod 30 close to the rotating plate 32.

[0029] It should be noted that: in the initial state, the end of the top column 31 away from the fixing clamp 24 abuts against the outer arc wall of the drive shaft 13 and the spring telescopic rod is in a compressed state. When the groove 2 on the outer arc wall of the drive shaft 13 rotates to align with the top column 31, the spring telescopic rod is inserted into the groove 2 under the action of the top column 31, and then rotates synchronously with the drive shaft 13. A torsion spring is provided at the rotating connection between the rotating plate 32 and the inner wall of the groove one, and the reset spring is used to reset the slide bar 30. When the rotating plate 32 pushes the fixing ring and then pushes the top column 31 to leave the groove two, the winding roller 23 is no longer connected to the driving shaft 13. At this time, the scraper 21 drives the winding roller 23 to rotate in the opposite direction under the action of the damping spring. Although the scraper 21 no longer applies pressure to the slide bar 30 at this time, the top column 31 has a tendency to reset, but because the scraper 21 drives the winding roller 23 to rotate in the opposite direction, the top column 31 has been staggered with the groove two and will not be stuck again.

[0030] See also Figure 1-4 The present invention provides a technical solution: the cross-sectional radius of the opening of one end of the filter hole on the stirring filter plate 20 is smaller than the cross-sectional radius of the opening of the other end, and the two ends of the scraper 21 are slidably connected to the side wall of the stirring filter plate 20.

[0031] It should be noted that: in a possible embodiment, a groove three is provided on one side wall of the stirring filter plate 20 having filter holes, the length and width of the groove three are respectively close to the length and width of the stirring filter plate 20, the length direction of the scraper 21 is consistent with the width direction of the groove three, the two ends of the scraper 21 are slidably connected to the inner wall of the groove three, and the scraper 21 can slide along the length direction of the groove three; A slide groove 1 is provided on the inner wall of the groove 3, and the end of the scraper 21 is slidably connected in the slide groove 1, and a damping spring is fixedly connected to the side wall of the scraper 21 close to the sleeve shaft 12. When the scraper 21 is driven by the fixed pull rope 22 to move toward the sleeve shaft 12 until they collide with each other, the damping spring prevents the fixed pull rope 22 from being wound too tightly and breaking, and prevents some hard particles in the raw material from scratching or wearing the equipment. At the same time, the damping spring is used to assist the scraper 21 in resetting.

[0032] See also Figure 1-4 The present invention provides a technical solution: a plurality of the stirring filter plates 20 are arranged alternately along the axial direction of the sleeve shaft 12 , and the plurality of the stirring filter plates 20 located on the same horizontal plane are distributed in a ring array about the axis of the sleeve shaft 12 .

[0033] It should be noted that: a plurality of stirring filter plates 20 located in a horizontal plane can perform multi-stage screening on the stirred solution in the same area to prevent some large particles from passing over the stirring filter plates 20 due to the vortex generated by stirring.

[0034] See also Figure 1-4The present invention provides a technical solution: a plurality of stirring rods 14 distributed in a circular array are fixedly connected to the bottom end of the outer arc wall of the driving shaft 13, and the stirring rods 14 do not contact the stirring filter plate 20. A plurality of stirring blades 15 distributed in a circular array are fixedly connected to the bottom end of the outer arc wall of the driving shaft 13, and a side wall of the stirring blades 15 away from the bottom inner wall of the box body 10 is an inclined surface.

[0035] It should be noted that the stirring rod 14 and the stirring blade 15 are both used for stirring materials, wherein the inclined surface of the stirring blade 15 produces a pushing effect similar to that of a screw when rotating, and the stirring blade 15 also assists in driving the materials at the dead corner at the bottom of the box 10 to enter the stirring.

[0036] Working principle: The reduction motor 11 drives the driving shaft 13 to rotate, and the winding roller 23 does not rotate with the driving shaft 13 in the initial state. When the groove 2 on the outer arc wall of the driving shaft 13 rotates to align with the top column 31, the top column 31 is inserted into the groove 2 under the action of the spring telescopic rod, so that the winding roller 23 rotates synchronously with the driving shaft 13, and then the winding roller 23 drives the fixing clamp 24 to rotate, and then the sleeve shaft 12 is pulled and wound. During this period, the scraper 21 is synchronously driven to scrape the particles intercepted on the stirring filter plate 20, and carry large particles to the sleeve shaft 12, and the large particles are crushed under the squeezing of the scraper 21 and the sleeve shaft 12; When the scraper 21 moves to the side close to the sleeve shaft 12, the scraper 21 abuts against the slide bar 30. Since the fixed pull rope 22 has been wound up by the winding roller 23 at this time, as the winding roller 23 continues to rotate, the scraper 21 will be continuously pulled and exert more and more pressure on the slide bar 30, so that the slide bar 30 pushes the rotating plate 32 and then pushes the top column 31 to make it exit the groove 2. At this time, the winding roller 23 no longer rotates synchronously with the drive shaft 13, and the scraper 21 is reset under the action of the damping spring.
