Description

Technical Field

[0001] The utility model relates to the technical field of polishing molds, and more specifically, to a colorimetric dish polishing mold. Background Art

[0002] A colorimetric dish is generally a cuboid, with its bottom and two sides being frosted glass, and the other two sides being light-transmitting surfaces made of optical glass and bonded together. A colorimetric dish is the most commonly used device in photometric analysis. Attention should be paid to protecting the light-transmitting surface. When taking it, the frosted glass surface should be pinched. When polishing the colorimetric dish, a colorimetric dish polishing mold is required.

[0003] Currently, when processing a colorimetric dish, it is generally necessary to polish the glass surface of the colorimetric dish. However, when most current polishing equipment polishes the colorimetric dish, it can only polish one surface of the colorimetric dish. When it is necessary to polish other surfaces of the colorimetric dish, the colorimetric dish needs to be manually turned over first, and then re-fixed so that the polishing equipment can also polish other surfaces of the colorimetric dish. Although this method can also polish other surfaces of the colorimetric dish, the process of manually turning over and fixing the colorimetric dish is time-consuming and laborious, thus reducing the polishing efficiency of the colorimetric dish. Moreover, when polishing the colorimetric dish, dust and other impurities in the external environment may be adsorbed on the outside of the colorimetric dish. If the dust and other impurities are not adsorbed and removed, it will cause the dust and other impurities to affect the polishing effect of the colorimetric dish during the polishing process. In severe cases, it may even cause damage to the glass surface of the colorimetric dish, thereby affecting the normal use effect of the colorimetric dish. Summary of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1 - Figure 4 As shown in the figure, this embodiment provides a colorimetric cuvette polishing mold, including a processing table 1, and further including:

[0026] A C-shaped frame 5, located above the processing table 1. A polishing roller 6 is rotatably connected inside the C-shaped frame 5. A driving motor 22 is fixedly connected to the front surface of the C-shaped frame 5. The output shaft of the driving motor 22 is fixedly connected to one end of the polishing roller 6 through a coupling;

[0027] The first adjustment component is symmetrically arranged on the upper surface of the processing table 1 and is used for reciprocating the polishing roller 6 left and right;

[0028] Moving plates 8 are symmetrically arranged above the processing table 1. Electric telescopic rods 9 are symmetrically arranged on the upper surfaces of the two moving plates 8. The telescopic ends of every two electric telescopic rods 9 are fixedly connected to a fixed plate 10. An upper plate 11 is fixedly connected to the upper surface of the fixed plate 10. Rotating grooves for the rotation of the rotating rod 12 are respectively formed through the opposite sides of the two upper plates 11. A first knob 13 is fixedly connected to one end of the rotating rod 12. A clamping plate 34 is fixedly connected to the other end of the rotating rod 12. A colorimetric cuvette body 7 is arranged between the two clamping plates 34;

[0029] The flipping components are respectively arranged on the upper surfaces of the two upper plates 11 and are used to flip the colorimetric cell body 7;

[0030] The second adjustment component is arranged at the bottom of the processing table 1 and is used to adjust the distance between the two clamping plates 34;

[0031] The dust suction component is located above the processing table 1 and is used to absorb the dust adhered to the outside of the colorimetric dish body 7 .

[0032] The above working principle: when the cuvette body 7 needs to be polished, the cuvette body 7 only needs to be placed between the two clamping plates 34, and then the distance between the two clamping plates 34 is adjusted by the second adjusting component. When the opposite sides of the two clamping plates 34 are respectively in conflict with the two sides of the outer wall of the cuvette body 7, the cuvette body 7 can be effectively fixed. When the cuvette body 7 is fixed, the electric telescopic rod 9 starts to run, driving the fixed plate 10 to move synchronously, and the fixed plate 10 then drives the cuvette body 7 to move downward synchronously. When the bottom of the cuvette body 7 contacts the outside of the polishing roller 6, the driving motor 22 starts to run. At this time, the driving motor 22 can effectively drive the polishing roller 6 to rotate synchronously, so that the polishing roller 6 can effectively polish the cuvette body 7. While the driving motor 22 is running, the first adjusting component The components also start to run synchronously. At this time, the first adjustment component can effectively drive the polishing roller 6 to move back and forth left and right, so that the polishing roller 6 can perform a comprehensive polishing process on the colorimetric cell body 7. When it is necessary to polish other surfaces of the colorimetric cell body 7, the electric telescopic rod 9 will drive the colorimetric cell body 7 to be lifted synchronously. When the colorimetric cell body 7 and the polishing roller 6 are separated, the colorimetric cell body 7 can be flipped over by the flipping component, so that the polishing roller 6 can conveniently and effectively polish other surfaces of the colorimetric cell body 7. During the polishing process of the colorimetric cell body 7, the dust collection component also starts to run synchronously. At this time, the dust collection component can effectively absorb and remove impurities such as dust adhered to the outside of the colorimetric cell body 7, thereby preventing impurities such as dust from affecting the polishing effect of the colorimetric cell body 7, saving time and effort.

[0033] In order to effectively make the polishing roller 6 move left and right reciprocally, so that the polishing roller 6 can polish the cuvette body 7 more comprehensively, the first adjustment component includes adjustment plates 2 symmetrically arranged on the upper surface of the processing table 1. The inner side wall of the adjustment plate 2 is rotatably connected with a lead screw 20. The other ends of the two lead screws 20 extend to the outside of the adjustment plate 2 and are fixedly connected with limit disks 3. One side of one of the adjustment plates 2 is fixedly connected with a reciprocating motor 24. The output shaft of the reciprocating motor 24 is fixedly connected with one end of one of the lead screws 20 through a coupling. The two lead screws 20 are connected by a belt 19 and a driving wheel in a driving manner. Threaded blocks 21 are screwed on the outside of the two lead screws 20. Guide grooves for the threaded blocks 21 to move are provided on the upper surfaces of the two adjustment plates 2. The upper surfaces of the two threaded blocks 21 are fixedly connected with the bottom of the U-shaped frame 5. When it is necessary to make the polishing roller 6 move left and right reciprocally, the reciprocating motor 24 starts to operate, driving one of the lead screws 20 to rotate synchronously. Since the two lead screws 20 are connected by a belt 19 and a driving wheel in a driving manner, the two lead screws 20 will rotate synchronously at this time. The threaded blocks 21 will move synchronously on the outside of the lead screws 20, driving the U-shaped frame 5 to move synchronously. The U-shaped frame 5 then drives the polishing roller 6 to move synchronously. At this time, the polishing roller 6 can be made to move left and right reciprocally, thus effectively improving the polishing effect of the polishing roller 6 on the cuvette body 7. The two driving wheels are of different sizes, so they will not have any impact on the transmission relationship between the two lead screws 20.

[0034] Considering that when the colorimetric dish body 7 is polished, the other surfaces of the colorimetric dish body 7 also need to be polished, so the flip assembly includes mounting blocks 14 respectively arranged on the upper surfaces of the two upper plates 11, and the interior of the mounting blocks 14 is penetrated by a guide groove for the movement of the fixing rod 15, one end of the fixing rod 15 is fixedly connected with a pull ring, the outside of the fixing rod 15 is fixedly connected with a contact plate 16, the outside of the fixing rod 15 is sleeved with a reset spring 17, the reset spring 17 is in contact between the contact plate 16 and the mounting block 14, the outside of the rotating rod 12 is fixedly connected with a turntable 18, and the inner ring of the turntable 18 is provided with a guide groove for the movement of the fixing rod 15. When the colorimetric dish body 7 needs to be flipped, it is only necessary to pull the pull ring first, and the pull ring will drive the fixing rod 15 to rotate synchronously. Move, the fixed rod 15 then drives the abutment disk 16 to move synchronously, during the movement of the abutment disk 16, the reset spring 17 will be squeezed, when the fixed rod 15 is out of the guide groove inside the turntable 18, the first knob 13 can be rotated, at this time the first knob 13 will drive the rotating rod 12 to rotate synchronously, the rotating rod 12 then drives the splint 34 to rotate synchronously, the splint 34 then drives the cuvette body 7 to rotate synchronously, when the cuvette body 7 is flipped over, the pull ring is released, at this time the reset spring 17 is reset, driving the fixed rod 15 to move synchronously, when the fixed rod 15 is plugged into the guide groove inside the turntable 18, the rotating rod 12 can be locked, at this time the polishing roller 6 can effectively polish the other surfaces of the cuvette body 7.

[0035] In order to effectively adjust the distance between the two clamping plates 34, so that the clamping plates 34 can effectively fix and clamp the cuvette bodies 7 of different specifications, the second adjustment component includes a transmission plate 4 fixedly connected to the bottom of the processing table 1, the inner side wall of the transmission plate 4 is rotatably connected to a bidirectional threaded rod 26, the other end of the bidirectional threaded rod 26 extends to the outside of the transmission plate 4 and is fixedly connected to a second knob 25, the outside of the bidirectional threaded rod 26 is symmetrically provided with a threaded plate 27, the contact surface between the transmission plate 4 and the processing table 1 is provided with a guide groove for the threaded plate 27 to move, and the two threaded plates 27 are provided on the contact surface between the transmission plate 4 and the processing table 1. The upper surfaces of the plates 27 are fixedly connected to the bottoms of the two movable plates 8 respectively. When the distance between the two clamps 34 needs to be adjusted, it is only necessary to rotate the second knob 25. At this time, the second knob 25 will drive the bidirectional threaded rod 26 to rotate synchronously, and the two threaded plates 27 will move synchronously outside the bidirectional threaded rod 26, driving the movable plates 8 to move synchronously, and the movable plates 8 will then drive the clamps 34 to move synchronously. At this time, the distance between the two clamps 34 can be adjusted, so that the clamps 34 can effectively fix and clamp the cuvette bodies 7 of different specifications.

[0036] In order to effectively adsorb and filter impurities such as dust in the external environment, so as to prevent impurities such as dust from adhering to the outside of the colorimetric cell body 7 and affecting the polishing effect of the colorimetric cell body 7, the dust suction assembly includes a support frame 28 fixedly connected to the rear end surface of the processing table 1. The upper surface of the support frame 28 is fixedly connected with a dust suction pump 32. The bottom of the support frame 28 is fixedly connected with a dust suction hood 33. The air inlet end of the dust suction pump 32 is connected to the inside of the dust suction hood 33 through a pipeline.

At this time, the dust suction pump 32 can adsorb the dust outside the colorimetric cell body 7 through the dust suction hood 33, and then transmit the gas containing impurities such as dust to the inside of the filter cylinder 29 through the pipeline. When the gas containing impurities such as dust is adsorbed into the filter cylinder 29, the filter meshes 30 can effectively intercept and filter the impurities such as dust, and then discharge the filtered gas through the exhaust pipe 31. At this time, it can prevent impurities such as dust from affecting the polishing effect of the colorimetric cell body 7.

[0037] In addition, in order to effectively improve the stability of the moving plate 8 and the U-shaped frame 5 during movement, the upper surface of the processing table 1 is symmetrically provided with connecting plates 35. Between the two connecting plates 35, guide rods 36 are symmetrically provided. The bottoms of the two moving plates 8 are symmetrically provided with guide blocks 37.

Guide grooves for the guide rods 36 to move are opened inside the two guide plates 38. During the movement of the moving plate 8, it will drive the guide blocks 37 to move synchronously outside the guide rods 36. At this time, both the guide blocks 37 and the guide rods 36 can effectively play a role in limiting and guiding the movement of the moving plate 8, so as to effectively improve the stability of the moving plate 8 during movement.
