[0001] This utility model relates to the technical field of lipstick testing equipment, and in particular to a lipstick fixing device and a breaking force testing device. Background Technology
[0002] In related technologies, the breaking force of lipstick is tested using a breaking force testing device. The tester fills the lipstick into packaging material to form a semi-finished lipstick. The packaging material is then secured with clamps, thus fixing the entire semi-finished lipstick under the breaking force testing device. The probe of the breaking force testing device is pressed against the lipstick until it breaks.
[0003] However, in actual testing applications, the break point of the paste is not at the contact point between the probe and the paste. The break point of the paste appears in other places, which causes the measured breaking force data to fluctuate greatly and is unstable, making it difficult to statistically analyze and use the breaking force data. Utility Model Content

The first end fixing structure is used to fix one end of the ointment to be tested, and the second end fixing structure is used to fix the other end of the ointment to be tested, so that the ointment to be tested is placed between the first end fixing structure and the second end fixing structure. The probe movable channel, which extends along a second direction, is disposed between the first end fixing structure and the second end fixing structure. The two ends of the probe movable channel in the first direction are respectively connected to the first end fixing structure and the second end fixing structure.

[0009] In some embodiments, the probe movable channel extends through the bottom surface of the mounting base along the second direction to form a second opening.
[0010] In some embodiments, the first opening and the second opening have the same cross-sectional shape perpendicular to the second direction and are aligned in the second direction.
[0011] In some embodiments, the probe active channel is configured as a uniform cross-section groove extending along the second direction.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0034] Breaking strength is a very important indicator for lipstick products. It reflects whether the lipstick is prone to breaking during storage, transportation, or consumer use, and also reflects its flexibility. Consequently, formulation engineers can adjust the formula based on the breaking strength indicator to reduce breakage and improve the lipstick's flexibility.
[0035] In related technologies, the breaking force of lipstick is detected using a breaking force detection device.
[0036] The testers fill the packaging material with the lipstick to form a semi-finished product. The packaging material is then fixed with clamps to secure the entire semi-finished lipstick under the breaking force testing device. The probe of the breaking force testing device is pressed against the lipstick until it breaks.
[0037] In practical applications, the applicant found that if the paste is relatively soft or hard, the break point of the paste is not at the contact point between the probe and the paste. The break point of the paste appears in other places, which causes the measured breaking force data to fluctuate greatly and is unstable, making it difficult to collect and use the breaking force data.
[0038] Therefore, the applicant proposed a paste fixing device 100 to change the way the paste is fixed in order to obtain more stable and less fluctuating breaking force data.
[0039] The following is for reference. Figures 1-7 This invention describes a paste fixing device 100 and a breaking force detection device 1000 according to embodiments of the present invention.
[0040] Example 1
[0041] like Figure 1 As shown, this embodiment provides a paste fixing device 100, which includes a first end fixing structure 11 and a second end fixing structure 12. The first end fixing structure 11 and the second end fixing structure 12 are spaced apart in a first direction D1. The first end fixing structure 11 can fix one end of the paste to be tested, and the second end fixing structure 12 can fix the other end of the paste to be tested, so that the paste to be tested is placed between the first end fixing structure 11 and the second end fixing structure 12.
[0042] The ointment fixing structure also includes a probe movable channel 14, which is located between the first end fixing structure 11 and the second end fixing structure 12. The two ends of the probe movable channel 14 in the first direction D1 are respectively connected to the first end fixing structure 11 and the second end fixing structure 12. That is to say, one end of the probe movable channel 14 in the first direction D1 is connected to the first end fixing structure, and the other end of the probe movable channel 14 in the first direction D1 is connected to the second end fixing structure.
[0043] Therefore, it can be seen that the probe 220 moves along the probe movement channel 14, and the probe 220 can act vertically on the suspended part of the paste to be tested along the probe movement channel 14, that is, the probe 220 touches the suspended part of the paste to be tested and breaks the paste to be tested.
[0044] In use, the testing personnel place the paste to be tested on the paste fixing device 100. The first end fixing structure 11 fixes one end of the paste to be tested, and the second end fixing structure 12 fixes the other end of the paste to be tested. Part of the paste to be tested is suspended in the probe moving channel 14. Then, the probe 220 of the breaking force testing device 1000 is aligned with the probe moving channel 14. The probe 220 enters the probe moving channel 14 and moves until it touches the paste to be tested. The probe 220 continues to move along the probe moving channel 14 until the paste to be tested is broken.
[0045] In related technologies, the clamping element is usually clamped at one end of the paste connecting to the packaging material, and the paste forms a cantilever structure. The fixing method of only fixing one end of the paste causes the break point of the paste to often occur at a position that is not in contact with the probe 220, which in turn leads to unstable detection of the breaking force.
[0046] Unlike related technologies, the paste fixing device 100 provided in this embodiment uses a first end fixing structure 11 and a second end fixing structure 12 to fix both ends of the paste. This allows a portion of the paste to be tested to be positioned between the first end fixing structure 11 and the second end fixing structure 12. The probe 220 of the breaking force detection device 1000 abuts against and breaks the paste along the probe movement channel 14 between the two end fixing structures. This fixing method secures both ends of the paste, making it easier for the paste to break and break at the point of force application of the probe 220, thus obtaining more stable and less fluctuating breaking force data.
[0047] Example 2
[0048] This embodiment is basically the same as Embodiment 1, except that it proposes a specific structure for a paste fixing device 100.
[0049] like Figure 1 and Figure 2 As shown, further, the second direction D2 is the vertical direction, and the first direction D1 is parallel to the horizontal direction.
[0050] like Figures 1-3 As shown, the ointment fixing device 100 also includes a fixing base 1. The first end fixing structure 11, the second end fixing structure 12, and the probe movable channel 14 are constructed as a groove structure formed on the fixing base 1. The probe movable channel 14, the first end fixing structure 11, and the second end fixing structure 12 all penetrate through the top surface 101 of the fixing base 1 along the second direction D2 and respectively form a first opening 141, a first feed port 151, and a second feed port 152. The first opening 141 is also used to allow the probe 220 to enter the probe movable channel 14. The penetration depth of the first end fixing structure 11 and the second end fixing structure 12 in the second direction D2 is H1, and the extension length of the probe movable channel 14 in the second direction D2 is H2, wherein H2 > H1.
[0051] Specifically, the first end fixing structure 11 and the second end fixing structure 12 support the paste to be tested from the bottom; the probe 220 moves downward along the probe movement channel 14 starting from the first opening 141, and then the probe 220 can press against and break the paste to be tested.
[0052] In this embodiment, by creating a groove structure on the fixing base 1 to form a first end fixing structure 11, a second end fixing structure 12, and a probe moving channel 14, the ointment fixing device 100 has a compact structure and saves costs.
[0053] In some specific examples, the ointment fixing device 100 also includes a fixing base 1, a first end fixing structure 11 configured as a first fixing groove formed on the fixing base 1, a second end fixing structure 12 configured as a second fixing groove formed on the fixing base 1, and a probe moving channel 14 configured as a first clearance groove formed on the fixing base 1; the first clearance groove, the first fixing groove, and the second fixing groove all pass through the top surface 101 of the fixing base 1 along the second direction D2 and respectively form a first opening 141, a first feed port 151, and a second feed port 152.
[0054] The first opening 141, the first feed inlet 151, and the second feed inlet 152 together form the feed inlet 15 for mounting the paste to be tested. After installation, the bottom walls of the first and second fixing grooves support the lower surface of the paste, and the paste to be tested corresponding to the position of the first clearance groove can be suspended.
[0055] Example 3
[0056] like Figure 1 and Figure 4 As shown, this embodiment is basically the same as embodiment two, except that the probe movement channel 14 further penetrates the bottom surface 102 of the fixing base 1 along the second direction D2 to form a second opening 142. After the probe 220 breaks off the ointment, it continues to move a portion of the ointment, which is discharged from the probe movement channel 14 through the second opening 142. At the same time, the setting of the second opening 142 helps to reduce the probability of the probe 220 being damaged by hitting the fixing base 1, thereby protecting the probe 220.
[0057] like Figure 1 , Figure 3 and Figure 4 As shown, the probe movable channel 14 is further constructed as a uniform cross-section groove extending along the second direction D2. That is, the probe 220 extends along the second direction D2, and the probe movable channel 14 has the same cross-sectional shape perpendicular to the second direction D2 in its extension direction. This further simplifies the structure of the ointment fixing device 100 and further reduces the probability of the probe 220 being damaged by hitting the fixing seat 1.
[0058] Example 4
[0059] like Figure 1 and Figure 3 As shown, the first end fixing structure 11 and the second end fixing structure 12 are symmetrically arranged in the first direction D1. The operator can easily and quickly align the two ends of the paste with the first end fixing structure 11 and the second end fixing structure 12 according to the symmetry, and this arrangement can make the fixation of the paste to be tested more balanced in the clearance space.
[0060] like Figure 1 and Figure 3 As shown, both the first end fixing structure 11 and the second end fixing structure 12 are constructed as cylindrical grooves extending along the first direction D1. The cross-sectional shape of the cylindrical groove perpendicular to the first direction D1 is square or arc-shaped. The specific cross-sectional shape of the cylindrical groove can be further adjusted according to actual needs, so that the cylindrical groove matches the cross-sectional shape of the paste, thereby making the fixation of the paste to be tested more balanced within the clearance space. For example, for some cylindrical pastes to be tested, the arc-shaped cylindrical groove can evenly wrap around the end of the paste, preventing it from rolling or shifting during the testing process. As another example, for some square pastes to be tested, the square-shaped cylindrical groove can fit tightly against the surface of the paste.
[0061] It should be emphasized that the paste to be tested can be poured and cooled in a specially designed paste fixing fixture to make the shape of the paste to be tested consistent with that of the cylindrical groove, thereby making the fit between the cylindrical groove and the paste tighter.
[0062] Example 5
[0063] like Figure 5 As shown, this utility model also proposes a breaking force detection device 1000. The breaking force detection device 1000 includes a detection device 200 and the above-mentioned paste fixing device 100. The detection device 200 includes a driving device 210, a probe 220 and a sensor. The driving device 210 is used to drive the probe 220 to move. The sensor is electrically connected to the probe 220 and is used to obtain the pressure applied by the probe 220. The probe 220 is movably disposed in the probe movement channel 14 and is used to cut the paste to be tested.
[0064] Example 6
[0065] like Figure 7As shown, the breaking force detection device 1000 further includes a bracket 300; the bracket 300 is provided with a first positioning structure 310, and the lower surface of the fixing seat 1 of the paste fixing device 100 is provided with a second positioning structure 16 that cooperates with the first positioning structure 310. Through the positioning cooperation between the first positioning structure 310 and the second positioning structure 16, the fixing position of the paste fixing device 100 can be quickly positioned.
[0066] like Figure 5 and 6 As shown in Embodiment 2, the probe 220 is vertically positioned above the bracket 300. The driving device 210 is used to drive the probe 220 downwards and break the paste to be tested.
[0067] Example 7
[0068] like Figure 7 As shown, one of the first positioning structure 310 and the second positioning structure 16 is configured as a positioning groove, and the other is configured as a positioning boss.
[0069] Specifically, the first positioning structure 310 is constructed as a positioning groove, and the second positioning structure 16 is constructed as a positioning boss connected to the lower surface of the fixed base 1. A through groove is also provided on the positioning boss, and the through groove is connected to the probe moving channel 14.
