Description

Technical Field

[0001] This utility model relates to the field of cigarette filter rod parameter measurement technology, specifically, to a multi-point hardness measuring device for cigarette filter rods. Background Technology

[0002] According to the Chinese tobacco industry standard YC / T28.6-1996, hardness is defined as the percentage of the radial diameter of a sample after being compressed to its diameter before compression within a certain period of time. Therefore, the hardness index of cigarettes is a relatively important physical indicator. Its quality affects both the structural stability and shape retention of the cigarette itself, as well as the user's smoking experience, making it an important indicator in cigarette production.

[0003] Currently, the mainstream method for hardness testing is to apply pressure to the outside of the cigarette filter rod using hardness testing equipment to obtain the actual hardness of the cigarette filter rod.

[0004] For example, the invention patent application with application number 202010352243.7 and invention title: "A sliding pressure type cigarette hardness measuring device" uses external pressure to reflect the hardness value.

[0005] However, in actual production, cigarette filter rods are gradually filled with materials such as tobacco. It is very likely that due to problems with the construction process or materials, the distribution of the filter rod is not uniform, which is reflected in the hardness index, meaning that the hardness index varies in different places.

[0006] Current application solutions can only obtain the hardness value at a specific point or random point, and cannot perform hardness detection at multiple points along the length of the cigarette filter rod.

[0007] In order to solve the above problems, people have been seeking an ideal technological solution. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing a multi-point hardness measuring device for cigarette filter rods that can measure the hardness of multiple points along the length of the filter rod.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is: a multi-point hardness measuring device for cigarette filter rods, comprising a support, a pressure application component, and a platform component;

[0010] The pressure application assembly is mounted on a bracket, and the pressure application assembly includes a pressure head that can apply pressure downward in a vertical direction and a force sensor for responding to the pressure of the pressure head;

[0011] The platform assembly includes a platform, a platform moving mechanism, and a table surface. The platform moving mechanism is used to drive the platform to move in a horizontal direction. The table surface is disposed on the upper surface of the platform and has a groove for supporting cigarette filter rods. The length direction of the groove is the same as the movement direction of the platform moving mechanism.

[0012] Based on the above, the platform moving mechanism includes a linear slide mounted on the lower part of the support, and the platform is mounted on the moving end of the linear slide via a slider.

[0013] Based on the above, the bottom surface of the tank is a plane, and the pressure application assembly also includes a distance sensor for detecting the downward pressing distance of the pressure head.

[0014] A multi-point hardness measuring device for cigarette filter rods includes a support, a pressure application component, and a platform component;

[0015] The pressure application assembly is mounted on the bracket. The pressure application assembly includes a lateral moving mechanism, a pressure head that can apply pressure downward in the vertical direction, and a force sensor for responding to the pressure of the pressure head. The lateral moving mechanism is mounted on the bracket, and the pressure head is mounted on the moving end of the lateral moving mechanism.

[0016] The platform assembly includes a platform and a table surface fixedly mounted on a bracket. The table surface is disposed on the upper surface of the platform, and a groove for supporting cigarette filter rods is provided on the table surface. The length direction of the groove is the same as the movement direction of the transverse moving mechanism.

[0017] Based on the above, a grating ruler is provided on the bracket corresponding to the lateral movement mechanism.

[0018] Based on the above, the lateral moving mechanism and the vertical driving mechanism of the pressure head constitute a two-stage slide.

[0019] A multi-point hardness measuring device for cigarette filter rods includes a support, a pressure application component, a platform component, and a cigarette filter rod position adjustment component;

[0020] The pressure application assembly is mounted on a bracket, and the pressure application assembly includes a pressure head that can apply pressure downward in a vertical direction and a force sensor for responding to the pressure of the pressure head;

[0021] The platform assembly includes a platform and a table surface fixedly mounted on a bracket. The table surface is disposed on the upper surface of the platform and has a groove for supporting cigarette filter rods.

[0022] The cigarette filter rod position adjustment assembly includes a robotic arm that is set at the same height as the platform. The locking position of the robotic arm is coaxial with the support position of the groove. The robotic arm can move linearly in the horizontal direction, and the direction of movement of the robotic arm is the same as the length direction of the groove.

[0023] Based on the above, the area in the tank corresponding to the pressure head being pressed down is set as a plane, and the plane is at the same height as the bottom of the tank.

[0024] Based on the above, the robotic arm is a chuck.

[0025] Based on the above, the cigarette filter rod position adjustment assembly is integrally installed on the bracket or adjacent to the bracket.

[0026] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model has the following advantages:

[0027] Since it is necessary to perform hardness testing on multiple points of the cigarette filter rod to reflect the hardness distribution of the cigarette filter rod, this application adopts three schemes.

[0035] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0036] Example 1

[0037] like Figure 1 and Figure 2 As shown, a multi-point hardness measuring device for cigarette filter rods includes a support 1, a pressure application component 2, and a platform component 3.

[0038] The pressure application component 2 is mounted on the bracket 1. The pressure application component 2 includes a pressure head 21 that can apply pressure downward in the vertical direction and a force sensor 22 for responding to the pressure of the pressure head.

[0039] In this embodiment, the pressure head 21 is driven by an independent lifting slide 23 to achieve lifting control. The lifting slide 23 is installed on the bracket 1. Specifically, the lifting slide 23 drives a cantilever 24 to lift and lower. A pressure rod 25 is hung on the cantilever. The bottom end of the pressure rod 25 is sequentially equipped with a force sensor 22 and the pressure head 21. On the side of the bracket 1 corresponding to the pressure head 21, a distance sensor 26 for detecting the downward pressing distance of the pressure head 21 is also installed.

[0040] The platform assembly 3 includes a platform 31, a platform moving mechanism 32, and a table surface 33. The platform moving mechanism 32 drives the platform 31 to move horizontally. The table surface 33 is disposed on the upper end surface of the platform 31. The table surface 33 is provided with a groove 34 for supporting the cigarette filter rod 4. The bottom surface of the groove 34 is flat to facilitate stable support during hardness measurement. The length direction of the groove 34 is the same as the movement direction of the platform moving mechanism 32. In this embodiment, the platform moving mechanism 32 includes a linear slide mounted on the lower part of the bracket 1. In other embodiments, other linear movement mechanisms, such as linear motors, may also be used.

[0041] Working principle explanation:

[0042] Place the cigarette filter rod 4 in the tank 34 to prepare for the hardness test.

[0043] First, move the stage assembly 3 so that one end of the cigarette filter rod 4 is at the test position, control the pressure head 21 to press down on the surface of the cigarette filter rod 4, and the force sensor 22 acquires a value, records and saves it.

[0044] Then, the platform assembly 3 is moved so that the second point of the cigarette filter rod 4 is at the test position, and the pressure head 21 is controlled to press down on the surface of the cigarette filter rod 4. The force sensor 22 acquires the second value, records it, and saves it.

[0045] Similarly, multiple test points within a certain range of the cigarette filter rod 4 are tested and recorded, and multiple data are recorded and saved. By observing and analyzing these data, the overall hardness characteristics of the cigarette filter rod 4 are determined.

[0046] Example 2

[0047] like Figure 3 and Figure 4 As shown, a multi-point hardness measuring device for cigarette filter rods includes a support 1, a pressure application component 2, and a platform component 3.

[0048] The pressure application component 2 is mounted on the bracket 1. The pressure application component 2 includes a lateral moving mechanism 27, a pressure head 21 that can apply pressure downward in the vertical direction, and a force sensor 22 for reacting to the pressure of the pressure head. The lateral moving mechanism 27 is mounted on the bracket 1, and the pressure head 21 is mounted on the moving end of the lateral moving mechanism 27.

[0049] Specifically, the main difference from Embodiment 1 is that the lateral moving mechanism 27 and the vertical driving mechanism of the pressure head, namely the lifting slide 23, form a two-stage slide. The lateral moving mechanism 27 adopts a lateral slide and serves as the first-stage slide, which is installed on the bracket 1. The lifting slide 23 serves as the second-stage slide and is installed on the first-stage slide. The two work together to realize the execution of horizontal and vertical movements.

[0050] The platform assembly 3 includes a platform 31 and a table surface 33 fixedly installed on the bracket 1. The table surface 33 is disposed on the upper end surface of the platform 31. The table surface 33 is provided with a groove 34 for supporting cigarette filter rods. The length direction of the groove 34 is the same as the movement direction of the transverse moving mechanism 27.

[0051] The main difference from Embodiment 1 is that the platform assembly 3 is fixed to the support 1 and will not move.

[0052] To improve the accuracy of the lateral movement mechanism 27, a grating ruler 28 is provided on the bracket 1 corresponding to the lateral movement mechanism 27.

[0053] Working principle explanation:

[0054] Similar to Example 1, the cigarette filter rod 4 is first placed in the tank 34 to prepare for testing.

[0055] First, move the entire pressure application assembly 2 to one end of the cigarette filter rod 4, control the pressure head 21 to press down on the surface of the cigarette filter rod 4, and the force sensor 22 acquires a value, records and saves it.

[0056] Then, move the entire pressure application assembly 2 to the second position of the cigarette filter rod 4, control the pressure head 21 to press down on the surface of the cigarette filter rod 4, and the force sensor 22 obtains the second value, records and saves it.

[0057] Similarly, multiple test points within a certain range of the cigarette filter rod 4 are tested and recorded, and multiple data are recorded and saved. By observing and analyzing these data, the overall hardness characteristics of the cigarette filter rod 4 are determined.

[0058] Example 3

[0059] like Figure 5 As shown, a multi-point hardness measuring device for cigarette filter rods includes a support 1, a pressure application component 2, a platform component 3, and a cigarette filter rod position adjustment component 5.

[0060] The pressure application component 2 is mounted on the bracket 1. The pressure application component 2 includes a pressure head 21 that can apply pressure downward in the vertical direction and a force sensor 22 for responding to the pressure of the pressure head. The structure of the pressure application component is the same as that of Embodiment 1. Its core feature is that it is fixed to the bracket and does not move laterally.

[0061] The platform assembly 3 includes a platform 31 and a table surface 33 fixedly installed on a bracket. The table surface 33 is disposed on the upper end surface of the platform 31, and a groove 34 for supporting cigarette filter rods is provided on the table surface 33.

[0062] The structure of the platform assembly 3 is the same as that of Embodiment 2. Its key feature is that it is fixed to the support and does not move laterally.

[0063] The cigarette filter rod position adjustment assembly 5 includes a robotic arm 51 set at the same height as the platform. The locking position of the robotic arm 51 is coaxial with the support position of the groove 34. The robotic arm 51 can move linearly in the horizontal direction. The moving direction of the robotic arm 51 is the same as the length direction of the groove 34. In this embodiment, the area in the groove 34 corresponding to the pressing head 21 is set as a plane. The plane is at the same height as the bottom of the groove 34. The robotic arm 51 is a chuck. The cigarette filter rod position adjustment assembly 5 is installed on the bracket 1 or adjacent to the bracket 1.

[0064] In this embodiment, the robotic arm 51 is driven by a linear slide 52, with a stroke length sufficient to detect at least one cigarette filter rod. In other embodiments, other linear motion mechanisms, such as linear motors, may also be used.

[0065] Working principle explanation:

[0066] The difference from Examples 1 and 2 is as follows:

[0067] During the testing process, the robotic arm 51 in the cigarette filter rod position adjustment assembly 5 grabs the cigarette filter rod 4 and adjusts its position, placing different test points in the test area below the pressure head 21 for testing, so as to obtain hardness data at different points.

[0068] 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.
