Description

Technical Field

[0001] This utility model relates to the field of color difference detection technology for bottled liquids, and in particular to an auxiliary device for detecting color difference in bottled liquids. Background Technology

[0002] Liquid packaging bottles are widely used in beverages, cosmetics, pharmaceuticals, and other products. Some of these bottles are transparent or semi-transparent, allowing people to directly observe the liquid inside. The liquid inside the bottle appears to have a certain color when viewed through the packaging.

[0003] In existing technologies, colorimeters are often used to detect the color of bottled liquids in order to control the color of the packaged product. Specifically, workers use a colorimeter to detect the liquid inside the bottle through the side wall of the packaging.

[0004] Measuring the color of liquids in curved bottles using an integrating sphere colorimeter is a significant challenge in the industry. The shape of the curved bottle can affect the colorimeter's results. Specifically, when the bottle is laid flat, the gas inside may be near the measuring window, affecting the results. Furthermore, during pressing, the bottle body may slip relative to the measuring window, also impacting the results. When the bottle is placed vertically, it's difficult to ensure that the contact area between the measuring window and the bottle body is less than 50% of the measuring window area, thus affecting the colorimeter's results. Ambient light also influences the results. Utility Model Content

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0049] An auxiliary device for detecting color difference in bottled liquids, used to assist a colorimeter 8 in measuring the color of the liquid inside a bottle 9.

[0050] In this embodiment, the colorimeter 8 is an integrating sphere colorimeter. The colorimeter 8 has a measurement window at its bottom, which is located at the rear end of the colorimeter 8.

[0051] In this embodiment, bottle 9 is an arc-shaped packaging bottle.

[0052] Please see Figures 1-3 As shown, the auxiliary device includes a base plate 1, an elastic pressure belt 2, a positioning bracket 3, a support frame 4, and an adjustment component 5.

Both ends of the elastic pressure band 2 are fixed to the edges of the through hole to elastically support the bottom of the colorimeter 8.

[0054] The positioning bracket 3 is placed within the support frame 4 and is located above the base plate 1. The rear end of the positioning bracket 3 is hinged to the base plate 1, and the front end of the positioning bracket 3 is hinged to the base plate 1 via the adjusting assembly 5. The top of the positioning bracket 3 has a positioning slot 31 for placing the bottle 9. The positioning slot 31 extends in the front-to-back direction. The front end of the positioning slot 31 is an open end. The bottle 9 is adapted to be inserted into the positioning slot 31 from the front end. The rear end of the positioning slot 31 is a closed end, and the rear end face of the positioning slot 31 is adapted to abut against the bottom of the bottle 9 to position the bottom of the bottle.

[0055] The adjusting component 5 is adapted to adjust the angle between the positioning bracket 3 and the horizontal direction so that the open end of the positioning slot 31 is higher than or flush with the closed end of the positioning slot 31. When a bottle 9 containing liquid is placed in the positioning slot 31, the gas in the bottle 9 can be moved away from the measuring window of the colorimeter 8 by adjusting the angle between the positioning bracket 3 and the horizontal direction (i.e., the degree of inclination of the positioning bracket 3), thereby effectively preventing the gas in the bottle from interfering with the detection results of the colorimeter 8.

[0056] The angle between the positioning base 3 and the horizontal direction is 0° to 20°. Preferably, the angle between the bottom of the positioning base 3 and the horizontal direction is 0° to 15°.

The second rod 52 extends vertically and is located below the first rod 51. The lower end of the first rod 51 is hinged to the top of the base plate 1. The two ends of the sleeve 53 are threadedly connected to the lower end of the first rod 51 and the upper end of the second rod 52, respectively. The operator can adjust the length of the adjusting component 5 by rotating the sleeve 53, thereby adjusting the angle between the positioning base 3 and the horizontal direction.

[0063] Further, please refer to Figures 2-3As shown, the support frame 4 includes a base rod 41, vertical rods 42, top rods 43, and connecting rods 44. The base rods 41 are horizontally positioned and extend in the front-to-back direction. There are two base rods 41, symmetrically positioned on the left and right sides of the top of the base plate 1. The top rods 43 are horizontally positioned and extend in the front-to-back direction. There are two top rods 43, each positioned above a corresponding base rod 41. The top rods 43 are connected to their respective base rods 41 via several vertical rods 42. The connecting rods 44 are horizontally positioned and extend in the left-to-right direction. There are two connecting rods 44, spaced apart. The two ends of each connecting rod 44 are connected to the two top rods 43. The inner walls of the two top rods 43 and the two connecting rods 44 form a through hole. This through hole is rectangular. The positioning bracket 3 is located below the top rod 43.

[0064] In this embodiment, the top rod 43 is connected to the corresponding bottom rod 41 via two vertical rods 42. The two ends of the elastic pressure band 2 are respectively connected to the corresponding top rods 43.

[0065] Furthermore, in order to improve the stability of the auxiliary device, the inner walls of the two base rods 41 are slidably connected to the left and right outer walls of the positioning bracket 3, respectively.

[0066] Furthermore, in order to smoothly press the colorimeter 8 downwards, the through hole is adapted to slide in connection with the colorimeter 8. Specifically, the inner walls of the two push rods 43 are slidably connected to the colorimeter 8, or the inner walls of the two connecting rods 44 are slidably connected to the colorimeter 8.

[0067] Furthermore, there are at least two elastic pressure bands 2. Several elastic pressure bands 2 are spaced apart. One elastic pressure band 2 is adapted to support the edge of the measuring window at the bottom of the colorimeter 8, exposing the measuring window. In this embodiment, there are two elastic pressure bands 2. One elastic pressure band 2 is adapted to support the edge of the measuring window, and the other elastic pressure band 2 is adapted to support the front end of the colorimeter 8.

[0068] Further, please refer to Figure 8 As shown, the auxiliary device also includes a light source box 6 to make the test results of the colorimeter 8 more accurate. The colorimeter 8 is suitable for testing within the light source box 6. The light source box 6 is a box with an open side. Multiple light sources are fixedly installed on the top of the inner cavity of the light source box 6. The inner cavity of the light source box 6 is white. The base plate 1, support frame 4, and positioning bracket 3 are suitable for placement within the inner cavity of the light source box 6. The inner cavity of the light source box 6 has a matte white coating to prevent the color of the inner cavity of the light source box 6 from interfering with the test results of the colorimeter 8.

[0069] The working principle of the auxiliary device is as follows:

[0070] The bottle 9 is placed in the positioning slot 31 by the limiting plate 7;

[0071] Adjust the angle between the positioning bracket 3 and the horizontal direction by adjusting component 5 so that the gas in bottle 9 is away from the measuring window of colorimeter 8;

[0072] Insert the colorimeter 8 into the through hole, and the elastic band 2 supports the colorimeter 8; press the colorimeter 8 down so that the elastic band 2 deforms elastically and the measuring window of the colorimeter 8 effectively contacts the bottle body of the bottle 9; then, the colorimeter 8 performs the test.

[0073] After the test is completed, the elastic pressure band 2 will be elastically reset so that the colorimeter 8 is away from the bottle 9, so that the colorimeter 8 can be removed from the through hole.

[0074] This invention effectively positions the bottle using a positioning bracket and adjustment components, ensuring the gas inside the bottle is away from the colorimeter's measuring window, thus guaranteeing effective detection by the auxiliary colorimeter. The support frame and elastic pressure band ensure the colorimeter's measuring window effectively contacts the bottle body. By replacing the limiting plates with different specifications, it can accommodate bottles of varying outer diameters, effectively improving the auxiliary device's adaptability. A light source box is included to prevent ambient light from affecting the colorimeter's detection results.

[0075] The above is a detailed description of one embodiment of the present utility model. However, the description is only a preferred embodiment of the present utility model and should not be considered as limiting the scope of the present utility model. All equivalent changes and improvements made within the scope of the claims of the present utility model should still fall within the patent protection scope of the present utility model.
