[0002] A plastic bottle raw material mixing uniformity testing device is a device used to evaluate the uniformity of plastic raw materials during the mixing process. It typically analyzes the characteristics of the mixture through optical, physical, or chemical methods. For example, when using optical properties for testing, the mixture is irradiated with light of a specific wavelength and the changes in reflected or transmitted light are measured to determine the degree of uniformity of the mixture. Density testing methods can also be used to evaluate uniformity by measuring the density at different sampling points. These devices are widely used in plastic production to ensure uniform mixing of raw materials, thereby improving product quality and production efficiency.

This multi-point sampling method can ensure that the test results can accurately reflect the uniformity of the entire mixing system and avoid test errors caused by raw material stratification or uneven local mixing. However, sampling at a high temperature and molten state requires operators to come into contact with high-temperature materials, which increases safety risks.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0028] Please see Figure 1-6 This utility model provides a technical solution:

[0029] A device for detecting the uniformity of mixing of raw materials for plastic bottles includes a frame plate 1, a detection probe 2, and a mixing furnace 6. A servo motor 3 is fixedly connected to the upper end of the frame plate 1. A drive assembly 4 is fixedly connected to the end of the main shaft of the servo motor 3. A sampling assembly 5 is installed inside the drive assembly 4. The drive assembly 4 includes a movable plate 41 and a hydraulic rod 42. A fixed seat 44 is fixedly connected to the bottom end of the hydraulic rod 42. A guide sliding hole 45 is opened inside the fixed seat 44. A spring 46 is fixedly connected to the lower end of the fixed seat 44. The sampling assembly 5 includes a movable seat 51. An extension rod 52 is fixedly connected to the inner side of the movable seat 51. A first column block 54, a column 56, and a second column block 55 are fixedly connected to the bottom end of the extension rod 52 in sequence. A sealing ring 53 is fixedly connected to the outer side of both the column 56 and the second column block 55. The outer side of the sealing ring 53 is in contact with the inner side of the glass tube 57. An inner hole plate 58 is fixedly connected to the top end of the glass tube 57. The bottom end of the spring 46 is fixedly connected to the top end of the movable seat 51. The extension rod 52 slides inside the guide sliding hole 45.

[0030] As a further implementation of this solution, a hydraulic rod 42 is fixedly connected to the upper end of the movable plate 41, a guide rod 43 is slidably connected to the inner side of the movable plate 41, a fixed seat 44 is fixedly connected to the bottom end of the hydraulic rod 42, and a vertical plate 47 is fixedly connected to the lower end of the fixed seat 44. Through the above configuration, this structural design enables the device to move the fixed seat 44 and its lower end device up and down by driving the hydraulic rod 42. With the guide rod 43 sliding in the movable plate 41, the stability and accuracy of the movement process are improved, providing reliable mechanical support for subsequent sampling operations and ensuring the accuracy of the sampling position.

[0031] As a further implementation of this solution, a sliding hole is provided on the inner side of the movable plate 41, the guide rod 43 slides inside the sliding hole of the movable plate 41, and the piston rod of the hydraulic rod 42 slides inside the movable plate 41. There are two hydraulic rods 42. With the above arrangement, one hydraulic rod 42 directly drives the sampling component 5 to move downward as a whole, and the other hydraulic rod 42 can push the movable seat 51 to move downward. The other hydraulic rod 42 does not contact the movable seat 51, so as to avoid the two hydraulic rods 42 from moving synchronously.

[0032] As a further implementation of this solution, the bottom end of the upright plate 47 is fixedly connected to the top end of the movable seat 51. The upright plates 47 are distributed at the four corners of the fixed seat 44. The movable seat 51 slides between the multiple upright plates 47. Through the above arrangement, the upright plates 47 can separate the movable seat 51 and the fixed seat 44, and at the same time fix the movable seat 51 and the fixed seat 44, providing a space for the movable seat 51 to move.

[0033] As a further implementation of this solution, a detection probe 2 is fixedly connected to one side of the frame plate 1, the sampling component 5 and the drive component 4 are located at the upper end of the mixing furnace 6, and there are multiple detection probes 2, the number of which is the same as the number of glass cylinders 57. The main shaft of the servo motor 3 is fixedly connected to the bottom end of the movable plate 41. Through the above settings, the detection probes 2 can detect the uniformity of the mixing of the mixed raw materials inside the multiple glass cylinders 57 one by one.

[0034] As a further implementation of this solution, the guide slide hole 45 extends through the inner side of the fixed seat 44 from top to bottom. The number of guide slide holes 45 is the same as the number of extension rods 52. The spring 46 is sleeved on the outer side of the extension rod 52. Through the above arrangement, the spring 46 plays the role of resetting the movable seat 51 after it has descended. By sliding the extension rod 52 into the guide slide hole 45, the stability of the movable seat 51 when it moves downward can be improved, and the effectiveness of the spring 46 in resetting the movable seat 51 can be ensured.

[0035] As a further implementation of this solution, the inner side of the glass tube 57 is a hollow structure, the first column 54 and the second column 55 have the same diameter, and a gap is provided between the first column 54 and the second column 55. The extension rod 52 is embedded and installed inside the glass tube 57. With the above arrangement, the mixed raw materials can be stored between the first column 54 and the second column 55, which facilitates the detection probe 2 to detect them.

[0036] Workflow: When detecting the uniformity of mixed raw materials at different depths inside the mixing furnace 6, initially the drive assembly 4 and sampling assembly 5 are positioned to the left of the servo motor 3. The servo motor 3 is activated, causing the movable plate 41 to rotate. The movable plate 41 then rotates the drive assembly 4 and sampling assembly 5 as a whole. After the movable plate 41 rotates 180 degrees, the sampling assembly 5 is vertically aligned with the mixing furnace 6. The hydraulic rod 42 is then activated, causing the fixed base 44 and the device at its lower end to move downwards. The fixed base 44 then moves the guide rod 43 downwards, and the guide rod 43 slides on the movable plate 44. Inside the movable plate 41, the guide rod 43 improves the stability of the fixed seat 44 when it moves downward. At this time, multiple glass tubes 57 are immersed inside the mixing furnace 6. The hydraulic rod 42 at the left end is activated. Since the left end of the movable seat 51 protrudes from the left end of the fixed seat 44, when the piston rod of the hydraulic rod 42 at the left end moves downward, the hydraulic rod 42 at the left end pushes the movable seat 51 downward. The movable seat 51 drives the extension rod 52 and the lower end structure of the extension rod 52 to move downward simultaneously. The movable seat 51 drives the spring 46 to extend, while the extension rod 52 slides inside the guide hole 45. At this time, the second column 55 and the column 56 protrude from the lower end of the glass cylinder 57, while the first column 54 remains inside the glass cylinder 57. The mixing material inside the mixing furnace 6 enters the glass cylinder 57 and is simultaneously located below the first column 54. When the hydraulic rod 42 on the left is activated, it retracts the piston rod. Under the elastic recovery action of the spring 46, the movable seat 51 moves upward, thereby driving the second column 55 into the glass cylinder 57 via the extension rod 52. This allows the mixing material to be stored inside the glass cylinder 57, thus enabling sampling of the material at different depths inside the mixing furnace 6. As the sampling component 5 passes through the hydraulic rod 42 on the right end, it is moved out of the mixing furnace 6. The servo motor 3 then rotates the drive component 4 and the sampling component 5 by 180 degrees, so that the detection probe 2 can detect the uniformity of the mixed raw materials between the first column 54 and the second column 55. After the detection is completed, the sampling component 5 is cleaned after cooling. Through the above setting principle, the device can extract mixed raw materials at different depths, improve the accuracy of the mixed raw material detection results, and at the same time, no operator is required, avoiding safety risks.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
