Description

Technical Field

[0001] This utility model relates to the field of polyurethane production technology, and more specifically, to a sampling and testing device for polyurethane production. Background Technology

[0002] Polyurethane is a polymer compound that is prepared using a variety of different raw materials and processes. Currently, in the production process of polyurethane, sampling equipment is required to sample the raw materials for testing purposes.

[0003] The existing publicly available technology, application number CN202220362447.3, discloses a sampling device for polyurethane production that avoids contamination of raw materials. This device employs a sampling mechanism where a protruding head is inserted into the powdered raw material during sampling, allowing the powder to be collected into the sampling chamber via a sampling groove. This design differs from the traditional method of sampling using a sampling spoon, facilitating sampling. Furthermore, an anti-contamination mechanism is included: after sampling, a spring-loaded anti-contamination tube moves downwards along the shell and tube body, covering the outside of the sampling groove. This prevents sample contamination during raw material transfer, ensuring the accuracy of subsequent structural testing.

[0004] However, the above-mentioned patent still has certain drawbacks in use: although it can store samples to achieve anti-contamination treatment, the structure used for sampling is relatively simple, and it can only perform one sampling operation at a time. It cannot sample polyurethane from different locations at the same time, and subsequent operations need to be performed frequently, which increases the labor intensity of personnel, reduces the sampling effect of the device, and makes the practicality of the structure not ideal.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a sampling and testing device for polyurethane production, which has the advantages of multiple sampling, good sampling effect, and strong practicality, thereby solving the problems mentioned in the background technology.

[0007] To achieve the advantages of multiple sampling, good sampling effect, and strong practicality mentioned above, the specific technical solution adopted by this utility model is as follows:

[0008] A sampling and testing device for polyurethane production includes a sampling cylinder and a protruding head. Several sets of sample boxes are evenly installed inside the sampling cylinder. A feed inlet is opened on one side of the sample box on the surface of the sampling cylinder. A sealing plate is slidably connected inside the feed inlet at the middle of the inner wall of the sampling cylinder. A pull rod is installed at one end of the sealing plate. One end of the pull rod passes through one side of the sampling cylinder. A fixing seat is fixedly installed on the outer periphery of the pull rod on the surface of the sampling cylinder. An opening is opened on the surface of the fixing seat.

[0009] Furthermore, a spring is sleeved on the outer periphery of the pull rod inside the sampling cylinder, and the two ends of the spring are fixed to the inner wall of the sampling cylinder and the bottom end of the pull rod, respectively.

[0010] Furthermore, a protrusion is installed at the bottom of the sampling cylinder.

[0011] Furthermore, the protrusion has a conical structure.

[0012] Furthermore, a magnetic absorbing piece is provided at the middle position of one end of the sealing sheet.

[0013] Furthermore, a magnetic suction groove is provided at the middle position of one end of the feed inlet.

[0014] Furthermore, an indicator block is provided at one end of the pull rod.

[0015] Furthermore, the feed inlet position gradually moves upward.

[0016] Compared with the prior art, this utility model provides a sampling and testing device for polyurethane production, which has the following beneficial effects:

[0017] This utility model employs a pull rod, a sealing sheet, and a sample box. In actual use, personnel can directly insert the sampling tube into the polyurethane powder to be sampled through the protrusion at the bottom. Then, by pulling the corresponding length of the pull rod using the indicator block, the pull rod compresses the spring and moves the sealing sheet within the inner wall of the sampling tube, causing the sealing sheet to detach from the inlet. At this point, the polyurethane powder naturally slides into the sample box. Since there are multiple sets of sample boxes and pull rods, and each set of sample boxes is located in a different position, it is possible to achieve sampling at multiple depths at once, no longer limited to single-type sampling. It eliminates the need for repeated insertion sampling, reducing the labor intensity of personnel and improving the practicality of the structure. It has the advantages of multiple sampling, good sampling effect, and high practicality. Attached Figure Description

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, a sampling and testing device for polyurethane production is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, the sampling and testing device for polyurethane production according to an embodiment of the present invention includes a sampling cylinder 1 and a protrusion 10. Several sets of sample boxes 8 are evenly installed inside the sampling cylinder 1. A feed inlet 7 is opened on one side of the sample box 8 on the surface of the sampling cylinder 1. A sealing sheet 5 is slidably connected inside the feed inlet 7 at the middle position of the inner wall of the sampling cylinder 1. A pull rod 3 is installed at one end of the sealing sheet 5. One end of the pull rod 3 passes through one side of the sampling cylinder 1. A fixing seat 2 is fixedly installed on the outer periphery of the pull rod 3 on the surface of the sampling cylinder 1. An opening is opened on the surface of the fixing seat 2. The fixing seat 2 is set to restrict and guide the movement trajectory of the pull rod 3 to ensure that it moves straight up and down, so as to facilitate better movement of the sealing sheet 5. The opening is set to facilitate the movement and use of the pull rod 3.

[0028] In one embodiment, a spring 11 is sleeved on the outer periphery of the pull rod 3 inside the sampling cylinder 1. The two ends of the spring 11 are fixed to the inner wall of the sampling cylinder 1 and the bottom end of the pull rod 3, respectively. The spring 11 is provided to facilitate the return of the pull rod 3 to its original position after being released.

[0029] In one embodiment, a protrusion 10 is installed at the bottom of the sampling cylinder 1.

[0030] In one embodiment, the protrusion 10 has a conical structure. The structure of the protrusion 10 is designed to reduce the obstruction when inserting polyurethane powder, making it easier to insert and sample.

[0031] In one embodiment, a magnetic absorbing piece 6 is provided at the middle position of one end of the sealing sheet 5. The magnetic absorbing piece 6 is provided to cooperate with the magnetic groove 9 to achieve magnetic adsorption between the two, improve the sealing strength, and facilitate better use.

[0032] In one embodiment, a magnetic groove 9 is provided at the middle position of one end of the feed port 7. The magnetic groove 9 is provided to magnetically attract and fix the magnetic sheet 6, thereby enhancing the sealing effect.

[0033] In one embodiment, an indicator block 4 is provided at one end of the pull rod 3. The indicator block 4 is provided to facilitate personnel in determining the position of the pull rod 3 at the feed inlet 7, so as to facilitate personnel in sampling polyurethane at the required depth.

[0034] In one embodiment, the position of the feed inlet 7 is gradually moved upward. The adjustment of the position of the feed inlet 7 is to enable personnel to sample polyurethane at different depths, improve the accuracy of subsequent testing and analysis, and facilitate better use.

[0035] Working Principle: In actual use, personnel can directly insert the sampling cylinder 1 into the polyurethane powder to be sampled through the bottom protrusion 10. Then, by pulling the lever 3 corresponding to the indicator block 4, the lever 3 compresses the spring 11, causing the sealing plate 5 to move within the inner wall of the sampling cylinder 1, thus disengaging the sealing plate 5 from the feed inlet 7. At this point, the polyurethane powder will naturally slide into the sample box 8. Since there are multiple sets of sample boxes 8 and lever 3, and each set of sample boxes 8 is located in a different position, it is possible to achieve sampling at multiple depths at once, eliminating the need for repeated insertion sampling. This reduces the labor intensity of personnel and makes the structure more practical. The sampling process is improved. After sampling is completed, releasing the pull rod 3 allows it to return to its downward position via the deformation and reset of the spring 11. At this point, the sealing sheet 5 can be placed back on top of the inlet 7 to seal the sample box 8. The sealing sheet 5 and the surface of the inlet 7 are equipped with a magnetic suction plate 6 and a magnetic suction groove 9. Their mutual magnetic attraction enhances the stability of the connection, preventing sample leakage during transfer and effectively improving sample preservation. Then, an external polyurethane testing instrument can quickly analyze the polyurethane, facilitating timely adjustments to production. The device as a whole has the advantages of multiple sampling, good sampling effect, and strong practicality.
