Description

Technical Field

[0001] This utility model relates to the field of coating material processing technology, and in particular to a raw material screening device for optical coating production. Background Technology

[0002] Optical coatings are composed of materials such as oxides, metals, or rare earth materials. The optical coating process refers to depositing one or more thin films with specific functions on the surface of optical components or materials. These thin films improve the performance of optical components by controlling the reflection, refraction, absorption, and scattering properties of light.

[0003] Currently, in the production process of optical coating, screening devices are needed to screen the raw materials to remove impurities and particles that do not meet the requirements, thus preventing impurities from being mixed into the coating materials. One existing screening device for coating material production uses a vibrating motor to drive a screen plate to vibrate, achieving a screening effect. However, this device only uses a vibrating motor to provide localized vibration, resulting in weak vibration and poor screening effect on the coating materials. Furthermore, the screen plate's mesh is prone to clogging after long-term use. The screen plate is fixedly installed inside the screening box, making it inconvenient to disassemble, clean, or replace it regularly. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a raw material screening device for optical coating production, which drives the screening basket to reciprocate through a reciprocating component, resulting in better screening effect; and the screening basket can be disassembled through a fixing component, which facilitates regular cleaning.

[0005] This utility model provides a raw material screening device for optical coating production, comprising:

The bottom surface of the screening basket is provided with a plurality of screening mesh holes. The reciprocating assembly is used to drive the slide frame and the screening basket to reciprocate along the length direction of the first slide bar.

[0008] The material guiding mechanism, located below the screening mechanism, includes a material guiding plate that is inclined downwards in a direction away from the screening mechanism. The lower end of the material guiding plate extends through the discharge port to the outside of the screening box, and is used to guide the screened coating raw material out of the screening box.

[0009] Furthermore, the reciprocating assembly includes a first connecting rod, a second connecting rod, and a drive motor. One end of the first connecting rod is rotatably connected to one end of the sliding frame, and the other end is rotatably connected to one end of the second connecting rod. The other end of the second connecting rod is fixedly connected to the output end of the drive motor. The drive motor is fixedly installed on the outside of the screening box by a bracket.

[0010] Furthermore, the screening box has a through-hole on the side near the reciprocating assembly for the first connecting rod and the second connecting rod to pass through.

[0011] Furthermore, the sliding frame includes two sets of symmetrically arranged sliding plates, with two sets of guide rods arranged side by side between the two sets of sliding plates. Both ends of each sliding plate are slidably connected to the first sliding rod, and one side of any sliding plate is rotatably connected to the end of the second connecting rod away from the first connecting rod.

[0012] Furthermore, a sliding sleeve is provided on the outside of the guide rod, and the sliding sleeve is detachably connected to the screening basket through a fixing component. A first spring is also provided on the outside of the guide rod at both ends of the sliding sleeve. One end of the first spring is fixedly connected to the slide plate, and the other end is fixedly connected to the sliding sleeve.

[0013] Furthermore, two sets of fixing components are symmetrically arranged about the screening basket. Each fixing component includes multiple sets of second sliding rods fixedly mounted horizontally on the screening basket, a second spring sleeved on the outside of the second sliding rods, and a lever plate slidably connected to the multiple sets of second sliding rods. One end of the second spring is fixedly connected to the outer wall of the screening basket, and the other end is fixedly connected to the lever plate. A fixing block is fixedly mounted on the side of the lever plate away from the screening basket, and a fixing seat matching the fixing block is mounted on the side of the sliding sleeve close to the fixing block. A stop block is fixedly mounted on the end of the second sliding rod away from the screening basket.

[0014] Furthermore, an installation mechanism for mounting the feed funnel is provided above the screening mechanism. The installation mechanism includes two sets of third slide rods arranged in parallel inside the screening box. The third slide rods are slidably connected to a mounting frame, and the feed funnel is fixedly mounted on the mounting frame.

[0015] Furthermore, the third slide bar is provided with a plurality of fixing holes spaced apart along its length, and the mounting bracket is provided with fasteners, which are inserted into the fixing holes for fixation.

[0018] (1) This utility model can drive the sliding frame and the screening basket to move back and forth along the length of the first sliding rod by starting the reciprocating component. During the reciprocating movement of the screening basket, the coating raw material is screened. The frequent and rapid reciprocating movement of the screening basket can improve the screening effect of the coating raw material.

[0019] (2) The present invention has a first spring on the outside of the guide rod. When the screening basket moves back and forth, it will continue to move along the original direction of movement due to inertia, thereby impacting and compressing the first spring. Compared with the fixed setting, it can enhance the amplitude of the screening basket swaying along the water surface and improve the screening effect on the coating raw materials.

[0020] (3) The present invention has fixed components on both sides of the screening basket.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0038] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0039] Please refer to Figures 1-4 The present invention provides a raw material screening device for optical coating production, including a screening box 1, a screening mechanism 2 and a material guiding mechanism 3, wherein the screening mechanism 2 and the material guiding mechanism 3 are both arranged inside the screening box 1.

[0040] The top of the screening box 1 is set to be open, and a discharge port 11 is opened on one side of the screening box 1. A feed funnel 4 is set at the open. Specifically, the coating raw material falls into the screening mechanism 2 through the feed funnel 4.

[0041] The screening mechanism 2 is located below the feed hopper 4 and includes a first sliding rod 21 arranged horizontally inside the screening box 1, a sliding frame 22 slidably connected to the first sliding rod 21, a screening basket 23 installed on the sliding frame 22, and a reciprocating assembly 24 connected to one end of the sliding frame 22. The bottom surface of the screening basket 23 has several screening mesh holes. The reciprocating assembly 24 is used to drive the sliding frame 22 and the screening basket 23 to move back and forth along the length direction of the first sliding rod 21. Specifically, the first sliding rod 21 is symmetrically arranged in two sets about the width direction of the screening box 1 to provide stable support for the sliding frame 22 and keep the sliding frame 22 and the screening basket 23 balanced. The four sides of the screening basket 22 are provided with outer edges to prevent the coating material placed on its top surface from falling off the edge during the movement. During the movement of the screening basket 22 along the length direction of the first sliding rod 21, the coating material on its top surface falls through the mesh holes of the screen. Larger impurities remain on the top surface of the screening basket 22. After screening, the impurities are manually removed.

[0042] The material guiding mechanism 3 is located below the screening mechanism 2 and includes a material guiding plate 31 that is inclined downward in a direction away from the screening mechanism 2. The lower end of the material guiding plate 31 extends through the discharge port 11 to the outside of the screening box 1 and is used to guide the screened coating raw material to be discharged out of the screening box 1.

[0043] In this embodiment, when screening the coating raw materials, the coating raw materials are poured into the feed funnel 4. The outlet of the feed funnel 4 is located above the screening basket 23. The coating raw materials fall into the screening basket 23. The reciprocating component 24 drives the sliding frame 22 and the screening basket 23 to move back and forth along the length direction of the first sliding rod 21. During the reciprocating movement, the coating raw materials that meet the requirements in the screening basket 23 fall down and slide out from the outlet 11 after being guided by the guide component 3. A collection device can be placed at the lower end of the guide plate 31 to collect the screened coating raw materials. Impurities larger than the sieve mesh remain on the screening basket 23. The impurities are manually removed to complete the screening of the coating raw materials. Compared with the use of a vibrating motor, the frequent and rapid reciprocating movement of the screening basket 23 can improve the screening effect of the coating raw materials.

[0044] In a preferred embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the reciprocating assembly 24 includes a first connecting rod 241, a second connecting rod 242, and a drive motor 243. One end of the first connecting rod 241 is rotatably connected to one end of the sliding frame 22, and the other end is rotatably connected to one end of the second connecting rod 242. The other end of the second connecting rod 242 is fixedly connected to the output end of the drive motor 243. The drive motor 243 is fixedly installed on the outside of the screening box 1 by a bracket.

[0045] Preferred, such as Figure 1As shown, the screening box 1 has a through-hole 12 on the side near the reciprocating assembly 24 for the first connecting rod 241 and the second connecting rod 242 to pass through.

[0046] In this embodiment, starting the drive motor 243 can drive the second connecting rod 242 to make circular motion around the axis of the output shaft of the drive motor 243. Under the transmission of the first connecting rod 241 and the limitation of the first sliding rod 21, the sliding frame 22 and the screening basket 23 are driven to move back and forth along the length direction of the first sliding rod 21, thereby driving the screening basket 23.

[0047] In a preferred embodiment, such as Figure 1 and Figure 2 As shown, the sliding frame 22 includes two sets of symmetrically arranged sliding plates 221. Two sets of guide rods 222 are arranged side-by-side between the two sets of sliding plates 221. First sliding rods 21 are slidably connected to both ends of each sliding plate 221. One side of any sliding plate 221 is rotatably connected to the end of a second connecting rod 242 away from the first connecting rod 241. Specifically, two sets of first sliding rods 21 are arranged side-by-side to provide stable support for the sliding frame 22 and improve the stability of the sliding frame 22 during movement; two sets of guide rods 222 are arranged side-by-side to provide stable support for the screening basket 23.

[0048] In a preferred embodiment, such as Figure 2 and Figure 3 As shown, a sliding sleeve 25 is provided on the outside of the guide rod 222. The sliding sleeve 25 is detachably connected to the screening basket 23 through the fixing component 26. A first spring 27 is also provided on the outside of the guide rod 222 at both ends of the sliding sleeve 25. One end of the first spring 27 is fixedly connected to the slide plate 221, and the other end is fixedly connected to the sliding sleeve 25.

[0049] In this embodiment, when the reciprocating component 24 drives the sliding frame 22 to reciprocate along the length direction of the first sliding rod 21, the screening basket 23 also moves synchronously. Since the screening basket 23 is mounted on the sliding sleeve 25 through the fixing component 26, and the sliding sleeve 25 is slidably connected to the guide rod 222, the screening basket 23 can also slide relative to the guide rod 222. Therefore, the screening basket 23 will continue to move along the original direction of movement due to inertia, thereby impacting and compressing the first spring 27. Compared with the fixed setting, it can enhance the swaying amplitude of the screening basket along the water surface and improve the screening effect on the coating raw materials.

[0050] In a preferred embodiment, such as Figure 2 and Figure 3As shown, there are two sets of fixing components 26 symmetrically arranged about the screening basket 1. The fixing components 26 include multiple sets of second slide rods 261 fixedly arranged horizontally on the screening basket 1, second springs 262 sleeved on the outside of the second slide rods 261, and actuating plates 263 slidably connected to the multiple sets of second slide rods 261. One end of the second spring 262 is fixedly connected to the outer wall of the screening basket 1, and the other end is fixedly connected to the actuating plate 263. A fixing block 264 is fixedly arranged on the side of the actuating plate 263 away from the screening basket 1. A fixing seat 265 matching the fixing block 264 is arranged on the side of the sliding sleeve 25 close to the fixing block 264.

[0051] In this embodiment, two or more sets of fixing base 265 and fixing block 264 are provided in one-to-one correspondence. The fixing base 265 has a fixing hole on the side facing the fixing block 264. The fixing block 264 is inserted into the fixing hole for fixation. Multiple sets of second spring 262 are provided. The elastic force of multiple sets of second spring 262 makes the fixing block 265 stably inserted into the fixing base 265 for fixation.

[0052] When it is necessary to disassemble the screening basket 1, press the actuating plate 263 with both hands in the direction of mutual contact, so that the second spring 262 is compressed, and the fixing block 264 is disengaged from the fixing seat 265, thus completing the quick disassembly of the screening basket 1; the structure is simple, easy to operate, and convenient.

[0053] Preferably, a stop 266 is fixedly provided at the end of the second slide bar 261 away from the screening basket 1. Specifically, the stop 266 is provided to prevent the actuating plate 263 from slipping.

[0054] In a preferred embodiment, such as Figure 1 and Figure 4 As shown, an installation mechanism 5 for installing the feed hopper 4 is provided above the screening mechanism 3. The installation mechanism 5 includes two sets of third slide rods 51 arranged in parallel in the screening box 1. The third slide rods 51 are slidably connected to the installation frame 52, and the feed hopper 4 is fixedly installed on the installation frame 52.

[0055] In this embodiment, two sets of third slide bars 51 are arranged side by side, and the third slide bars 51 are arranged close to the inner side wall of the screening box 1. The gap between the two sets of third slide bars 51 allows the screening basket 23 to be taken out.

[0056] During screening, the feed funnel 4 is pushed along the length of the third slide bar 51 to place the feed funnel 4 above the screening basket 23, so that the coating material in the feed funnel 4 falls into the screening basket 23. When screening is finished, the feed funnel 4 is pushed to one end of the third slide bar 51 to facilitate the removal of larger impurities remaining on the screening basket 23 from the open opening, and also to facilitate the removal of the screening basket 23 from the open opening. This avoids the need to disassemble the feed funnel 4 when disassembling the screening basket 23.

[0057] In a preferred embodiment, such as Figure 1 and Figure 4 As shown, the third slide bar 51 has multiple fixing holes 511 spaced apart along its length, and the mounting bracket 52 is provided with fasteners 521, which are inserted into the fixing holes 511 for fixation.

[0058] In this embodiment, the fixing hole 511 is a threaded hole, the fastener 521 is a bolt, and the mounting bracket 52 is provided with four sliders in a rectangular shape. The sliders are slidably connected to the third slide rod 511. The sliders are provided with mounting holes, and bolts are inserted into the mounting holes. The sliders are fixed to the third slide rod 51 by the bolts, thereby fixing the mounting bracket 52.

[0059] In a preferred embodiment, such as Figure 1 As shown, the material guiding mechanism 3 also includes a support plate 32 fixedly disposed below the material guiding plate 31. Several third springs 33 are disposed between the support plate 32 and the material guiding plate 31. A vibration motor 34 is installed at the bottom of the material guiding plate 31.

[0060] Specifically, the vibration motor 34 drives the guide plate 31 to vibrate, accelerating the sliding of the coating material. Under the action of the third spring 33, the vibration amplitude of the vibration motor 34 driving the guide plate 31 to vibrate is larger, increasing the vibration frequency and further increasing the speed at which the coating material slides down.

[0061] Working principle:

[0062] When screening coating materials, the coating materials are poured into the feed funnel 4. The outlet of the feed funnel 4 is located above the screening basket 23. The coating materials fall into the screening basket 23. The reciprocating component 24 drives the sliding frame 22 and the screening basket 23 to move back and forth along the length of the first sliding rod 21. During the reciprocating movement, the coating materials that meet the requirements fall into the screening basket 23 and slide out from the outlet 11 after being guided by the material guiding component 3. Impurities larger than the screening mesh remain on the screening basket 23. After screening, the impurities are manually removed, and the screening of coating materials is completed. Compared with the use of a vibrating motor, the frequent and rapid reciprocating movement of the screening basket 23 can improve the screening effect of coating materials.

[0063] When the screening basket 23 moves back and forth along the length of the first slide bar 21, the screening basket 23 will continue to move along the original direction of motion due to inertia, thereby impacting and compressing the first spring 27. Compared with the fixed setting, this can enhance the swaying amplitude of the screening basket 23 along the water surface and improve the screening effect on the coating raw materials.

[0064] Furthermore, the screening basket 23 is detachably connected to the sliding sleeve 25 via the fixing component 26, which facilitates the disassembly of the screening basket 23 and its regular cleaning.
