Description

Technical Field

[0001] This utility model relates to the field of tobacco testing technology, specifically to a composite latex membrane for a cigarette or filter rod testing platform. Background Technology

[0002] In routine testing of cigarettes / filter rods, different test heads are usually required when testing cigarettes of different thicknesses. Currently, existing test stations typically have three types of test heads: coarse, medium, and fine. The latex tubes used for sealing and separating the test heads are also available in three sizes and have different lengths, making replacement particularly troublesome.

[0003] like Figure 1 As shown, there are three types of latex film: coarse-stretch composite latex film holder, medium-stretch composite latex film holder, and fine-stretch composite latex film holder, as well as three types of latex film. The latex film is cylindrical with two rings at both ends for securing it to specific positions on the latex film holder.

[0004] In actual use, the fixing frame and the latex film are separate structures, requiring temporary installation, fixing, and adjustment of each one, which is relatively cumbersome.

[0005] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a composite latex membrane for cigarette or filter rod testing platforms that can be adapted to use with cigarette filter rods of different sizes.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a composite latex membrane for a cigarette or filter rod testing platform, comprising a cylindrical latex membrane body and two annular ribs disposed at both ends of the latex membrane body;

[0008] The inner diameter of the middle region of the latex film body is smaller than the inner diameter of the two end regions.

[0009] Based on the above, the middle region of the latex film body is cylindrical.

[0010] Based on the above, the two ends of the latex film body are funnel-shaped.

[0011] Based on the above, the length of the middle region and the two end regions of the latex film body are divided into three equal parts.

[0012] Based on the above, the lengths of the two end regions of the latex film body are equal and both are greater than the length of the middle region.

[0013] Based on the above, the lengths of the two end regions of the latex film body are equal and both are shorter than the length of the middle region.

[0014] Based on the above, the latex film body and the annular rib are integrally formed structures.

[0015] Based on the above, the latex film body and the annular rib are separate structures, which are connected and fixed by pasting, winding or melting.

[0016] Based on the above, the annular rib is an elastic body.

[0017] Based on the above, the material of the annular rib is latex.

[0018] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages:

[0019] The newly designed composite latex membrane is not a traditional cylindrical structure in its natural state, but rather a shape with consistent dimensions at both ends and a tapering shape in the middle. Since latex has the ability to deform, after being installed in a latex membrane holder, the opening formed in the middle becomes a deformable perforation, which can be used for cigarettes or filter rods of different diameters.

[0024] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0025] like Figure 2 and Figure 3 As shown, a composite latex membrane for a cigarette or filter rod testing platform includes a cylindrical latex membrane body 1 and two annular ribs 2 disposed at both ends of the latex membrane body.

[0026] The inner diameter of the middle region 11 of the latex film body 1 is smaller than the inner diameter of the two end regions 12.

[0027] Specifically, in this embodiment, the middle region 11 of the latex film body 1 is cylindrical, presenting a thin round tube shape, and its size can be determined according to the size of the slim cigarette, slightly smaller than the diameter of the slim cigarette; the two end regions 12 of the latex film body 1 are funnel-shaped, and the inner diameter gradually increases from the two ends of the middle region 11 outwards.

[0028] In practical applications, the inner diameter of the middle region 11 can usually be designed to be 4.5-5mm.

[0029] Working principle explanation:

[0030] The composite latex film needs to be used with the latex film fixing frame 3. The latex film fixing frame 3 has annular grooves at both ends for locking the annular ribs 2. The composite latex film is inserted into the latex film fixing frame 3, and the annular ribs 2 at both ends are locked into the annular grooves of the latex film fixing frame 3 to complete the assembly.

[0031] In the initial state, the inner diameter of the middle region 11 of the latex film body 1 is smaller than the inner diameter of the latex film holder 3, forming a trumpet-shaped curve on the overall cross-section. The minimum diameter is smaller than the inner diameter of a slim cigarette or filter rod, so that a slim cigarette or filter rod can be easily inserted into it for use.

[0032] When a medium or thick cigarette is used, the smallest diameter deforms and expands, but it can still be sealed and wrapped around the outside of the cigarette or filter rod.

[0033] When it is necessary to remove the cigarette or filter rod, negative pressure is drawn through the negative pressure hole 4 on the latex film holder 3 to adsorb and open the middle and end areas of the latex film body 1, thereby ensuring the feeding of the cigarette and the removal after the test is completed.

[0034] This composite latex membrane allows for universal application in experiments with coarse, medium, and fine cigarettes or filter rods, eliminating the need to change the test head.

[0035] In other preferred embodiments, the shape of the middle region can also be conical or trumpet-shaped, and the shapes of the two end regions can also be frustum-shaped or other shapes.

[0036] In terms of length design, in other embodiments, the length of the middle region and the two end regions of the latex film body are divided into three equal parts; or the lengths of the two end regions of the latex film body are equal and both are greater than the length of the middle region; or the lengths of the two end regions of the latex film body are equal and both are less than the length of the middle region.

[0037] There is no fixed rule for its length design. Different length ratios can be designed according to different application requirements. Generally speaking, when a high degree of sealing is required, the length of the middle area needs to be long enough. When the thickness of the latex film fixing frame is thin, the length of the two end areas can be slightly shorter. When the thickness of the latex film fixing frame is thick, the length of the two end areas can be slightly longer.

[0038] In a preferred embodiment, the latex film body and the annular rib are integrally formed.

[0039] In other embodiments, the latex film body and the annular rib are separate structures, which are connected and fixed by pasting, winding or melting. The annular rib has a structure similar to a rubber band, providing a certain structural strength and toughness to ensure the structural strength of the latex film.

[0040] In a preferred embodiment, the annular rib is an elastomer, and the material of the annular rib is latex, which is the same as the material of the latex film body, to ensure the stability of the overall structure.

[0041] This latex film overcomes the shortcomings of the previous three types of films, which were not interchangeable and could be used to measure cigarettes of different thicknesses, including coarse, medium, and fine.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model 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 this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
