Description

Technical Field

[0001] This invention relates to the field of tobacco production technology, and in particular to a filter rod suction resistance testing device and method. Background Technology

[0002] In related technologies, when using a comprehensive testing instrument to detect the physical properties of samples, electrostatic adsorption often occurs during the suction resistance test due to the long length or complex material of the filter rod, which is prone to being attracted by the latex tube during friction. As a result, the filter rod often cannot fall freely under its own weight after the suction resistance test, causing the test process to be interrupted. Frequent interruptions significantly reduce the testing efficiency of the testing equipment and require handling by the testing personnel, which not only increases the complexity of the testing personnel's work but also increases their workload, ultimately leading to a significant reduction in overall work efficiency.

[0003] It should be noted that the information disclosed in the background section of this invention is intended only to enhance the understanding of the overall background of this invention, and should not be construed as an admission or in any way implying that such information constitutes prior art known to those skilled in the art. Summary of the Invention

[0004] This invention provides a filter rod suction resistance testing device and method, which helps the filter rod to fall smoothly out of the testing device after the suction resistance test, thereby improving the testing efficiency.

[0005] According to one aspect of the present invention, a filter rod suction resistance testing device is provided, comprising:

[0006] A suction resistance test assembly includes a first test element, the first test element including a first filter rod channel for placing a filter rod; and

[0007] An antistatic device includes a generator for generating a charged airflow and an air blowing section communicating with a first filter rod channel. The air blowing section is configured to blow the charged airflow into the first filter rod channel to blow the filter rod out of the first test piece after the filter rod's suction resistance test is completed.

[0008] In some embodiments, the generator includes an intake section and an ionization section, the intake section being connected to an air blowing section and configured to introduce air into the static eliminator, and the ionization section being configured to ionize the air entering the static eliminator to form a charged airflow.

[0009] In some embodiments, the suction resistance testing assembly further includes a first annular cavity, which is disposed between the air blowing section and the first filter rod channel and communicates with the air blowing section and the first filter rod channel.

[0010] In some embodiments, the suction resistance test assembly further includes a second test element, a first annular cavity is disposed within the second test element, the second test element is further provided with a second annular cavity communicating with the first annular cavity and a second filter rod channel communicating with the first filter rod channel, the center line of the first annular cavity and the center line of the second annular cavity extend in the same direction and the outer periphery of the first annular cavity is located outside the outer periphery of the second annular cavity, and the second annular cavity is communicating with the first filter rod channel.

[0011] In some embodiments, the centerline of the second annular cavity and the centerline of the second filter rod channel coincide with the centerline of the first filter rod channel.

[0012] In some embodiments, the second filter rod channel includes a first guide section whose cross-sectional area gradually decreases from one end away from the first filter rod channel to one end closer to the first filter rod channel.

[0013] In some embodiments, the suction resistance test assembly further includes a third test element connected between the first test element and the second test element.

[0016] In some embodiments, the blowing part is a pneumatic connector.

[0017] According to another aspect of the present invention, a filter rod suction resistance testing method based on the above-described filter rod suction resistance testing device is provided, comprising:

[0018] The filter rod is tested for suction resistance using a suction resistance testing assembly.

[0019] A charged airflow is generated by an antistatic device, and after the filter rod's suction resistance test is completed, the charged airflow is blown into the suction resistance test assembly to blow the filter rod out of the suction resistance test assembly.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limiting the scope of protection of this invention.

[0030] like Figure 1 As shown, in some embodiments of the filter rod suction resistance testing device provided by the present invention, the filter rod suction resistance testing device includes a suction resistance testing component and an antistatic device 3. The suction resistance testing component includes a first test piece 1, which includes a first filter rod channel 1a for placing the filter rod 2. The antistatic device 3 includes a generator 31 for generating charged airflow and an air blowing part 32 communicating with the first filter rod channel 1a. The air blowing part 32 is configured to blow charged airflow into the first filter rod channel 1a after the suction resistance test of the filter rod 2 is completed, so as to blow the filter rod 2 out of the first test piece 1.

[0031] In the above embodiment, by setting up the generator 31, the airflow (e.g., airflow) entering the static elimination device 3 can be ionized to generate charged airflow. Then, the charged airflow is blown into the first filter rod channel 1a where the filter rod 2 is placed by the blowing part 32. On the one hand, the charge in the airflow can neutralize the charge between the filter rod 2 and the first filter rod channel 1a, thereby eliminating the static electricity between the filter rod 2 and the first filter rod channel 1a. On the other hand, the airflow can also blow the filter rod 2 out of the first filter rod channel 1a, thereby avoiding the situation where the filter rod 2 cannot fall out of the suction resistance test assembly due to the electrostatic adsorption between the filter rod 2 and the first filter rod channel 1a. Therefore, the efficiency of the filter rod suction resistance test is improved, and the operation time of the tester is effectively saved.

[0032] like Figure 1 As shown, in some embodiments, the generator 31 includes an intake section 311 and an ionization section 312. The intake section 311 is connected to the blowing section 32 and is configured to introduce air into the static eliminator 3. The ionization section 312 is configured to ionize the air entering the static eliminator 3 to form a charged airflow.

[0033] In the above embodiment, the air intake 311 is used to introduce air into the static eliminator 3 so that the ionization 312 can further ionize the air. The ionization 312 can be composed of a high-voltage power generator and a discharge electrode (generally made into an ion needle). The air entering the static eliminator 3 is ionized into a large number of positive and negative ions by high-voltage corona discharge at the tip of the ion needle, thereby forming a charged airflow, that is, forming a static eliminator airflow. Then, the static eliminator airflow is blown into the first filter rod channel 1a by the air blowing 32 to neutralize the charge on the surface of the filter rod 2 and the first filter rod channel 1a, thereby eliminating static electricity.

[0034] like Figure 1 As shown, in some embodiments, the suction resistance test assembly further includes a first annular cavity 4b, which is disposed between the air blowing section 32 and the first filter rod channel 1a and communicates with the air blowing section 32 and the first filter rod channel 1a.

[0035] By setting a first annular cavity 4b between the air blowing section 32 and the first filter rod channel 1a, the airflow can be guided, so that the antistatic airflow blown out from the air blowing section 32 can form an annular flow surface and flow into the first filter rod channel 1a after passing through the first annular cavity 4b. This not only helps to increase the contact between the airflow and the surface of the filter rod 2 and improve the antistatic effect, but also facilitates the installation of the air blowing section 32. The airflow can be smoothly blown into the first filter rod channel 1a without adjusting the angle of the outlet of the air blowing section 32.

[0036] like Figure 1 As shown, in some embodiments, the suction resistance test assembly further includes a second test element 4. A first annular cavity 4b is disposed within the second test element 4. The second test element 4 also has a second annular cavity 4c communicating with the first annular cavity 4b and a second filter rod channel 4a communicating with the first filter rod channel 1a. The centerline of the first annular cavity 4b extends in the same direction as the centerline of the second annular cavity 4c, and the outer periphery of the first annular cavity 4b is located outside the outer periphery of the second annular cavity 4c. The second annular cavity 4c communicates with the first filter rod channel 1a.

[0037] In the above embodiment, the filter rod 2 enters the suction resistance test assembly through the second filter rod channel 4a for subsequent suction resistance testing. By setting the second annular cavity 4c, the flow direction of the airflow exiting the first annular cavity 4b can be further guided, such as... Figure 1As shown by the arrow, the airflow flowing from the static eliminator 3, which is perpendicular to the center line of the second filter rod channel 4a, is guided by the annular walls of the first annular cavity 4b and the second annular cavity 4c. At the outlet of the second annular cavity 4c, it becomes an airflow with an annular flow surface that flows parallel to the center line of the second filter rod channel 4a and toward the first filter rod channel 1a. This flow pattern not only helps to increase the contact between the airflow and the surface of the filter rod 2, achieving a good static eliminator effect, but also helps to push the filter rod 2 along its axial direction toward the outlet of the first filter rod channel 1a, thereby causing the aluminum rod 2 to detach from the suction resistance test assembly.

[0038] like Figure 1 As shown, in some embodiments, the center line of the second annular cavity 4c and the center line of the second filter rod channel 4a coincide with the center line of the first filter rod channel 1a.

[0039] By aligning the centerline of the second annular cavity 4c and the centerline of the second filter rod channel 4a with the centerline of the first filter rod channel 1a, it helps to guide the airflow from the second annular cavity 4c to flow towards the contact surface between the filter rod 2 and the first filter rod channel 1a, so that the static-eliminating airflow can fully contact the surface of the filter rod 2 and the wall of the first filter rod channel 1a, thereby achieving a good static-eliminating effect.

[0040] like Figure 1 As shown, in some embodiments, the second filter rod channel 4a includes a first guide section whose cross-sectional area gradually decreases from one end away from the first filter rod channel 1a to the end closer to the first filter rod channel 1a.

[0041] By setting up the first guide section, it is easier for testers to smoothly insert the filter rod 2 into the suction resistance test assembly before conducting the suction resistance test, thereby helping to improve the overall test efficiency.

[0042] like Figure 1 As shown, in some embodiments, the suction resistance test assembly further includes a third test element 5, which is connected between the first test element 1 and the second test element 4. The third test element 5 includes a third filter rod channel 5a, the first end of which is connected to the second annular cavity 4c and the second filter rod channel 4a, and the second end of which is connected to the first filter rod channel 1a.

[0043] In the above embodiment, before the suction resistance test begins, the filter rod 2 passes sequentially through the second filter rod channel 4a of the second test piece 4 and the third filter rod channel 5a of the third test piece 5, and enters the first filter rod channel 1a of the first test piece 1. The third test piece 5 can be used to connect or cooperate with related equipment (such as sensors) required in the suction resistance test. The size and specifications of the third test piece 5 can be set according to actual needs to adapt to different test requirements.

[0044] The outer diameter of the second annular cavity 4c should be set to be similar to and slightly smaller than the inlet diameter of the third filter rod channel 5a, so that the outlet airflow of the second annular cavity 4c can flow as smoothly and evenly as possible through the inner wall of the third filter rod channel 5a to the first filter rod channel 1a, thereby achieving a better static electricity removal effect and smoothly blowing the filter rod 2 out of the first filter rod channel 1a.

[0045] like Figure 1 As shown, in some embodiments, the third filter rod channel 5a includes a second guide section whose cross-sectional area gradually decreases from one end away from the first filter rod channel 1a to the end closer to the first filter rod channel 1a.

[0046] In the above embodiment, by setting the second guide section, not only can the movement of the filter rod 2 be guided, but also the airflow flowing out of the second annular cavity 4c can be guided, thereby improving the smoothness of airflow and ensuring the effect of static electricity removal.

[0047] In some embodiments, the filter rod suction resistance test apparatus further includes a fan configured to deliver compressed air to the generator 31.

[0048] Compared to directly introducing atmospheric pressure air into generator 31, supplying compressed air to generator 31 via a fan can greatly increase the airflow volume and velocity, thereby ensuring a good static electricity removal effect and increasing the success rate of blowing the filter rod 2 out of the suction resistance test assembly.

[0049] In some embodiments, the air blowing part 32 is a pneumatic connector.

[0050] Pneumatic connectors have advantages such as good sealing and convenient installation. In the above embodiment, by setting the air blowing part 32 as a pneumatic connector, the air blowing effect can be guaranteed, and the efficiency of testers in disassembling and assembling test equipment can be improved, thereby improving the overall test efficiency.

[0051] The specific structure of one embodiment of the filter rod suction resistance testing device of the present invention is described below:

[0052] like Figure 1 As shown, the filter rod suction resistance testing device includes a suction resistance testing component, an antistatic device 3, and a fan. The suction resistance testing component is used to perform suction resistance testing on the filter rod. The antistatic device 3 is used to generate charged airflow after the test is completed to blow the filter rod out of the suction resistance testing component. The fan is used to deliver compressed air to the antistatic device 3.

[0053] The suction resistance testing assembly includes a first test piece 1, a second test piece 4, and a third test piece 5. The first test piece 1, the second test piece 4, and the third test piece 5 are respectively provided with a first filter rod channel 1a, a second filter rod channel 4a, and a third filter rod channel 5a. The second test piece 4 also provides a first annular cavity 4b and a second annular cavity 4c. The static electricity removal device 3 includes a generator 31 and an air blowing section 32. The generator 31 includes an air intake section 311 and an ionization section 312. The fan is connected to the inlet of the air intake section 311, and the outlet of the air intake section 311... The air is connected to the inlet of the generator 31 and the air blowing section 32 in sequence. The outlet of the air blowing section 32 is connected to the first annular cavity 4b. The center lines of the first annular cavity 4b, the second annular cavity 4c, the first filter rod channel 1a, the second filter rod channel 4a and the third filter rod channel 5a all coincide. The outer diameter of the first annular cavity 4b is larger than the outer diameter of the second annular cavity 4c. The first filter rod channel 1a, the second filter rod channel 4a and the third filter rod channel 5a all include a guide section whose cross-sectional area gradually decreases from the inlet to the outlet of the self-absorption resistance test component.

[0054] In this embodiment, the discharge electrode of the ionization section 31 is an ion needle, and the blowing section 32 is a pneumatic connector.

[0055] refer to Figure 1 As shown in the diagram, when a filter rod resistance test is required, the tester inserts the filter rod 2 to be tested into the opening above the second filter rod channel 4a. The filter rod 2 falls along the second filter rod channel 4a and the third filter rod channel 5a, reaching the preset test position in the first filter rod channel 1a. After the test is completed, the fan and the static eliminator 3 are turned on, and a charged airflow (such as...) is introduced into the second filter rod channel 4a. Figure 1 As indicated by the arrow in the diagram, the airflow further flows to the position of filter rod 2, completing the static electricity removal process. The airflow then propels filter rod 2 out of the outlet of the first filter rod channel 1a, completing the current suction resistance test.

[0056] Through the description of several embodiments of the filter rod suction resistance testing device of the present invention, it can be seen that the present invention, by setting an antistatic device, can generate a charged airflow to eliminate static electricity between the filter rod and the first filter rod channel and blow the filter rod out of the suction resistance testing assembly. The filter rod suction resistance testing device of the present invention has a simple structure and is easy to operate. After the filter rod suction resistance test is completed, it can quickly detach the filter rod from the suction resistance testing assembly to facilitate the smooth progress of subsequent tests, effectively saving the operation time of the test personnel and improving the overall efficiency of the filter rod suction resistance test.

[0057] Based on the above-mentioned filter rod suction resistance testing device, the present invention also proposes a filter rod suction resistance testing method, which includes performing a suction resistance test on the filter rod 2 through a suction resistance testing component, generating a charged airflow through an antistatic device 3, and blowing the charged airflow into the suction resistance testing component after the suction resistance test of the filter rod 2 is completed, so as to blow the filter rod 2 out of the suction resistance testing component.

[0058] The positive technical effects of the filter rod suction resistance testing device in the above embodiments are also applicable to the filter rod suction resistance testing method, and will not be repeated here.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the present invention or equivalent substitutions can still be made to some technical features without departing from the principle of the present invention, and such modifications and equivalent substitutions should all be covered within the scope of the technical solutions claimed in the present invention.
