Description

A device and method for detecting the viscosity of cosmetics Technical Field

[0001] This invention relates to the field of liquid viscosity testing, and in particular to a device and method for testing the viscosity of cosmetics. Background Technology

[0002] Viscosity testing in cosmetics is a crucial step in quality control, directly impacting the product's usability, stability, and packaging performance. Touchscreen viscometers are one method for measuring cosmetic viscosity, an upgraded version of traditional rotational viscometers. Based on the rotational viscosity measurement method, viscosity is calculated by measuring the resistance of a rotating rotor in a fluid. Specifically, a suitable rotor is immersed in the cosmetic sample to be tested, and then a motor drives the rotor to rotate. During rotation, the viscous resistance of the cosmetic sample to the rotor is converted into an electrical signal by a torque sensor. The instrument automatically calculates the viscosity value based on the torque, rotor parameters, and rotational speed.

[0003] Sample homogeneity and whether the instrument is placed horizontally are factors affecting the accuracy of viscometer test results. In existing technologies, cosmetic samples are typically poured directly into a test cup, which is then placed on the instrument. During this process, the sample is prone to stratification and sedimentation, affecting sample homogeneity and thus the accuracy of the test results. Furthermore, existing technologies generally use leveling feet at the bottom of the instrument, requiring manual adjustment by the operator based on the surface of the work surface. This leveling method has significant errors, also affecting the accuracy of the test results. Additionally, existing technologies typically involve manually mounting the rotor to the motor output to homogenize the sample. This method requires high hand stability from the operator; hand tremors can easily damage precision electronic components such as torque sensors and slip rings, thus affecting the accuracy of the test results. Summary of the Invention

[0004] The purpose of this invention is to provide a cosmetic viscosity testing device and method that can effectively homogenize cosmetic samples in a testing cup, thereby improving the accuracy of the testing results.

[0005] The cosmetic viscosity testing device of the present invention includes an instrument frame, a rotor and a mounting bracket. The instrument frame and the mounting bracket are connected by a leveling component. The mounting bracket is provided with a drive source, an auxiliary mounting component and a supporting component.

[0006] The leveling component includes a horizontally arranged and mutually perpendicular connecting shaft 1 and connecting shaft 2. Connecting shaft 2 is fixedly mounted on the instrument frame. A sleeve is fitted onto the outside of connecting shaft 2 through a bearing. Connecting shaft 1 is radially mounted on the outer surface of the sleeve. There are two connecting shafts 1, located on both sides of the sleeve.

[0007] A suspension bracket is installed on the outside of the connecting shaft one via a bearing. The bottom of the suspension bracket is connected to the top of the mounting bracket. A counterweight is installed at the bottom of the mounting bracket. After the instrument rack is placed on the experimental table and left to stand, the center line of the overall structure consisting of the mounting bracket, drive source, auxiliary mounting components, support components, and counterweight will eventually be arranged vertically.

[0008] As a preferred embodiment of the present invention, the leveling component further includes a braking component for limiting the mounting bracket to remain stationary in its current state after the mounting bracket stops shaking.

[0009] As a preferred embodiment of the present invention, the braking assembly includes a hydraulic cylinder and a braking pipe. The two sides of the braking pipe are respectively connected to two connecting shafts. The braking pipe and the hydraulic cylinder are connected through a connecting pipe.

[0010] A brake disc is installed on the suspension bracket, and a brake disc is installed on the connecting shaft. The brake disc is coaxial with the connecting shaft, and the brake disc is coaxial with the connecting shaft.

[0011] The braking pipe has several notches, and brake disc one and brake disc two are located in the corresponding notches respectively;

[0012] The notch is open on both sides of the axis of brake disc one or brake disc two and a brake block is fitted thereon. The end face of the brake block is parallel to the end face of brake disc one or brake disc two.

[0013] As a preferred embodiment of the present invention, the brake block is provided with a hemispherical rubber protrusion at one end facing the brake disc 1 or brake disc 2.

[0014] As a preferred embodiment of the present invention, the auxiliary installation component is located below the drive source, and the auxiliary installation component includes a lifting bracket and a linear module 1 that drives the lifting bracket to move in the vertical direction.

[0015] The lifting support has two sliding supports that slide horizontally along its own sliding direction. The lifting support is equipped with a linear module three for driving the two sliding supports to move closer or further apart. Each of the two sliding supports is equipped with a clamping component.

[0016] As a preferred embodiment of the present invention, the clamping assembly includes a clamp disposed on one side of two sliding supports facing each other. The clamp is rotatably connected to the sliding supports. The clamp is in the shape of a vertically arranged semi-cylindrical shape. Each of the two clamps is provided with a side groove on one side facing each other. A half gear is fitted on the outer circumference of each clamp. When the sliding supports move with the clamps and the two clamps come into contact with each other to form a complete cylinder, the two half gears form a complete spur gear, and the two side grooves form a complete clamping groove.

[0017] As a preferred embodiment of the present invention, the clamping groove is divided into a lower cylindrical segment and an upper internal hexagonal segment along the center line.

[0018] As a preferred embodiment of the present invention, the lifting bracket is provided with a drive assembly for driving the half gear to rotate. The drive assembly includes a transmission shaft disposed on the lifting bracket, a motor for driving the transmission shaft to rotate, and a power transmission component disposed between the transmission shaft and the half gear. The driving component of the power transmission component moves together with the sliding bracket. The driving component is disposed outside the transmission shaft via a spline. When the driving component moves together with the sliding bracket, the transmission shaft continuously outputs power to the driving component. The driven component of the power transmission component forms a power connection with the half gear.

[0019] As a preferred embodiment of the present invention, the supporting component is located below the auxiliary installation component. The supporting component includes a connecting bracket and a linear module two that drives the connecting bracket to move in the vertical direction. The connecting bracket is provided with a rotating seat with its axis arranged vertically and a motor two that drives the rotating seat to rotate. A rotating disk is coaxially installed inside the rotating seat.

[0020] The rotating base is equipped with a clamping unit and a motor for driving the rotating disk to rotate. Several clamping units are arranged in an array along the circumference of the rotating base.

[0021] The clamping unit includes a guide rod extending radially along the rotating seat, a slider slidably mounted on the guide rod, a pin mounted on the upper surface of the slider, and a sliding guide engagement between the pin and a linkage hole mounted on the rotating disk. When the rotating disk rotates, the slider can move on the guide rod through the engagement between the linkage hole and the pin.

[0022] A support rod is provided at the upper end of the pin, and a clamping roller is provided on the upper surface of the support rod. The clamping roller is located above the rotating seat, and the rotating seat is provided with a clearance hole for avoiding the clamping roller.

[0023] The cosmetic viscosity detection method of the present invention includes the following steps:

[0024] Step 1: Place the instrument stand on the experimental table and place the test cup containing the cosmetic sample on the upper surface of the rotating seat;

[0025] Step 2: The rotating disk is rotated by the three-wheel drive motor, which brings all the clamping rollers closer together to self-center and clamp the detection cup;

[0026] Step 3: The experimenter moves the mounting bracket, causing it to swing along with the test cup. At the same time, the motor drives the rotating seat to rotate, which in turn rotates the test cup, thus homogenizing the cosmetic sample inside the test cup.

[0027] Step 4: Hydraulic medium is sent into the brake pipe through the hydraulic cylinder, so that the rubber protrusion on the brake pad contacts brake disc one or brake disc two. As the oil supply of the hydraulic cylinder gradually increases, the friction between the rubber protrusion and brake disc one or brake disc two increases synchronously, so as to limit the swaying amplitude of the mounting bracket.

[0028] When the hydraulic cylinder oil supply is cut off, the rubber protrusion loses contact with brake disc one or brake disc two.

[0029] After waiting for the preset time, the mounting bracket stops swaying and stabilizes. At this time, the hydraulic cylinder continues to supply oil, which clamps brake disc one and brake disc two through the brake blocks, keeping the mounting bracket in its current state.

[0030] Step 5: The linear module second drive moves the supporting component and the detection cup upward, so that the rotor extends into the detection cup;

[0031] Step Six: Drive the rotor to rotate using a drive source to detect the viscosity of the cosmetic sample.

[0032] Compared with the prior art, the beneficial effects of this invention are as follows:

[0033] 1. The active swinging of the mounting bracket can swing the test cup together. The swinging includes swinging along the axis of the first connecting shaft and swinging along the axis of the second connecting shaft. Combined with the rotation of the test cup by the rotating seat, it can effectively and quickly homogenize the cosmetic sample in the test cup, which can further improve the uniformity of the sample, thereby improving the accuracy of the final test results.

[0034] Second, by first hindering the swaying of brake disc one and brake disc two, allowing them to quickly stabilize, and then removing the hindering force, the swaying amplitude of the mounting bracket is reduced, and it can stabilize after a short time. Then, the mounting bracket is fixed in place, achieving the goal of quickly stabilizing the mounting bracket and keeping the rotor and the centerline of the detection cup vertical. The advantages are:

[0035] On the one hand, rapid stabilization can prevent cosmetic samples from separating due to prolonged static time, which would affect subsequent testing. On the other hand, keeping the rotor and the test cup vertical can further improve the accuracy of the test results. Furthermore, even if the mounting bracket swings with the test cup with a large amplitude, it can quickly stabilize, improving testing efficiency. Moreover, it can adapt to complex laboratory testing environments and quickly and automatically level itself. Automatic leveling refers to using the plumb line principle to keep the rotor and the test cup vertical.

[0036] Furthermore, the greater the swing amplitude of the mounting bracket, the more oil is supplied to the hydraulic cylinder, and the greater the friction between the rubber protrusion and brake disc one or brake disc two, thereby quickly reducing the swing amplitude of the mounting bracket and achieving the purpose of rapid and stable leveling.

[0037] Third, setting a level on the rotating seat has the technical advantage that after the test is completed and the test cup is removed, the experimenter can observe whether the level is horizontal, thus avoiding the possibility that the levelness problem caused by improper equipment operation during the test process may be overlooked by the experimenter and lead to inaccurate test results.

[0052] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0053] In the attached diagram of this plan, 'a' refers to the testing cup that holds the cosmetic sample to be tested.

[0054] Referring to Figures 1-12, a cosmetic viscosity testing device includes an instrument frame 100, a rotor 102, and a mounting bracket 101.

[0055] The instrument rack 100 and the mounting bracket 101 are connected by a leveling component 200. The mounting bracket 101 is equipped with a drive source 103, an auxiliary mounting component 300, and a support component 400, wherein:

[0056] The auxiliary installation component 300 is used to automatically install the rotor 102 onto the output end of the drive source 103. It should be noted that the drive source 103 is equivalent to the motor structure used to drive the rotor 102 to rotate in the existing touch viscometer, which is feasible with existing technology and will not be described in detail. In addition, compared with the existing technology where the rotor 102 is manually installed onto the drive source 103, this solution adopts an automatic installation method. Therefore, it solves the problem mentioned in the background technology that the experimenter's hand tremor can easily cause damage to precision electronic components such as torque sensor and through-hole slip ring, thus affecting the accuracy of the test results.

[0057] The support component 400 is used to hold the test cup containing cosmetic samples.

[0058] I. Leveling component 200:

[0059] Referring to Figures 3-6, the leveling component 200 includes a horizontally arranged connecting shaft. There are two connecting shafts that are perpendicular to each other. The two connecting shafts are a second connecting shaft 205 fixedly mounted on the instrument frame 100 and a first connecting shaft 204 sleeved on the second connecting shaft 205. Furthermore, a sleeve 2051 is sleeved on the outside of the second connecting shaft 205 through a bearing. The first connecting shaft 204 is radially arranged on the outer circular surface of the sleeve 2051. There are two first connecting shafts 204, which are located on both sides of the sleeve 2051 respectively.

[0060] A suspension bracket 203 is provided on the outside of the connecting shaft 204 via a bearing. The bottom of the suspension bracket 203 is connected to the top of the mounting bracket 101. A counterweight 104 is provided on the bottom of the mounting bracket 101.

[0061] The connection shaft 1 204 and the connection shaft 2 205 allow the mounting bracket 101 to deflect in any direction. Therefore, after the instrument rack 100 is placed on the experimental table or desktop and left to stand for a period of time, based on the principle of the verticality of the plumb bob's gravity, the overall structure (named the detection mechanism for ease of description) consisting of the mounting bracket 101, the drive source 103, the auxiliary mounting component 300, the support component 400, and the counterweight 104 will continuously shake. Ultimately, the center line of the detection mechanism remains vertical. At the same time, since the axis of the drive source 103 and the axis of the rotating disk 404 of the support component 400 coincide with this center line, the vertical arrangement accuracy of the drive source 103 and the detection cup placed on the rotating disk 404 can be guaranteed. The principle of the verticality of the plumb bob's gravity is achievable with existing technology and will not be elaborated further.

[0062] The leveling component 200 also includes a braking component, which is used to limit the mounting bracket 101 to remain stationary after the mounting bracket 101 stops shaking, thereby providing a stable environment for subsequent testing.

[0063] Specifically, the braking assembly includes a hydraulic cylinder 201 and a braking pipe 208. The two sides of the braking pipe 208 are connected to two connecting shafts 204 respectively. The outer surface of the braking pipe 208 is provided with a connecting nozzle 2081. The connecting nozzle 2081 and the hydraulic cylinder 201 are connected through a connecting pipe 202.

[0064] A brake disc 206 is mounted on the suspension bracket 203, and a brake disc 207 is mounted on the connecting shaft 205. The brake disc 206 is coaxial with the connecting shaft 204, and the brake disc 207 is coaxial with the connecting shaft 205.

[0065] The braking pipe 208 has several notches 2082, and brake disc 1 206 and brake disc 207 are located in the corresponding notches 2082.

[0066] The notch 2082 is open on both sides along the axis of brake disc 1 206 or brake disc 207 and is fitted with brake block 209. The end face of brake block 209 is parallel to the end face of brake disc 1 206 or brake disc 207. The end of brake block 209 facing brake disc 1 206 or brake disc 207 is provided with a hemispherical rubber protrusion 2091.

[0067] Hydraulic medium can be delivered into the brake pipe 208 by hydraulic cylinder 201, so that the rubber protrusion 2091 on the brake block 209 abuts against the brake disc 206 or brake disc 207. As the oil supply of hydraulic cylinder 201 gradually increases, the friction between the rubber protrusion 2091 and the brake disc 206 or brake disc 207 also increases, thereby limiting the sway amplitude of the detection mechanism and reducing it. Then, the oil supply is stopped, and the rubber protrusion 2091 disengages from the brake disc 206 or brake disc 207. At this time, because the overall sway amplitude of the detection mechanism is low, the detection mechanism will stabilize after a short time. After that, the oil supply continues, and the brake block 209 clamps the brake disc 206 and brake disc 207, thereby keeping the detection mechanism stationary in its current state.

[0068] II. Auxiliary installation component 300:

[0069] Referring to Figures 7-10, the auxiliary mounting component 300 is located below the drive source 103.

[0070] The auxiliary installation component 300 includes a lifting bracket 301 and a linear module 105 that drives the lifting bracket 301 to move in the vertical direction. The linear module 105 and the linear module 106 mentioned later can both adopt existing electric telescopic rod technology or existing screw linear movement technology, etc.

[0071] A sliding bracket 305 is slidably mounted on the lifting bracket 301 along the horizontal direction. There are two sliding brackets 305 along their own sliding direction. The two sliding brackets 305 are driven by the linear module 302 to move closer to or further away from each other. Furthermore, the linear module 302 can adopt the following technology: the lead screw is divided into two threaded segments with opposite thread directions along the axis. The two threaded segments are respectively connected to the two sliding brackets 305. When the motor drives the lead screw to rotate, it can make the two sliding brackets 305 move closer to or further away from each other.

[0072] Each of the two sliding supports 305 is equipped with a clamping component.

[0073] Specifically, the clamping assembly includes a clamp 306 disposed on one side of the two sliding supports 305 facing each other. The clamp 306 is rotatably connected to the sliding supports 305, that is, the clamp 306 can rotate around its own axis. The clamp 306 is a vertically arranged semi-cylindrical shape.

[0074] Each of the two sleeves 306 has a side groove on one side facing each other. A half gear is fitted on the outer circular surface of each sleeve 306. When the sliding bracket 305 moves the sleeves 306 and the two sleeves 306 come into contact with each other to form a complete cylinder, the two half gears form a complete spur gear and the two side grooves form a complete clamping groove. Furthermore, the clamping groove is divided into a lower cylindrical section and an upper internal hexagonal section along the center line.

[0075] Referring to Figure 9, in the prior art, the rotor 102 includes a cylindrical shaft and a polygonal shaft in the shape of a regular hexagon. Therefore, in use, the experimenter holds the rotor 102 between the two side slots, with the polygonal shaft slightly higher than the upper hexagonal section of the clamping slot. Then, the linear module 302 drives the two sliding supports 305 to move closer to each other, so that the two clamps 306 come into contact with each other to form a complete cylinder, and the two side slots form a complete clamping slot. At this time, the cylindrical shaft of the rotor 102 is located in the lower cylindrical section of the clamping slot. Then, the experimenter positions the polygonal shaft of the rotor 102 in the upper hexagonal section of the clamping slot and releases the rotor 102 to place it on the auxiliary mounting component 300.

[0076] The lifting bracket 301 is equipped with a drive assembly for driving the half gear to rotate.

[0077] Specifically, the drive assembly includes a transmission shaft 304 mounted on the lifting bracket 301, a motor 303 for driving the transmission shaft 304 to rotate, and a power transmission component 307 disposed between the transmission shaft 304 and the half gear. Further, the driving component of the power transmission component 307 moves together with the sliding bracket 305. The driving component is splined outside the transmission shaft 304, and when the driving component moves with the sliding bracket 305, the transmission shaft 304 continuously outputs power to the driving component. The driven component of the power transmission component 307 forms a power connection with the half gear. Therefore, when the rotor 102 is placed on the auxiliary mounting component 300, the rotation... The rotor 102 is coaxially located below the drive source 103. Then, the motor 303 drives the sleeve 306 to rotate, and the sleeve 306 rotates together with the rotor 102. At the same time, the linear module 105 drives the lifting bracket 301 to move upward, thereby moving the rotor 102 upward together. At this time, the rotor 102 moves upward and rotates at the same time, so that the rotor 102 can be screwed into the drive source 103. It should be noted that in the prior art, the rotor 102 and the drive source 103 are also connected by threads, but they are manually screwed on. Similarly, moving downward and rotating at the same time can remove the rotor 102 from the drive source 103.

[0078] III. Supporting Components 400:

[0079] Referring to Figures 7, 11 and 12, the support member 400 is located below the auxiliary mounting member 300. It should be noted that after the rotor 102 is installed, the two sliding brackets 305 of the auxiliary mounting member 300 need to be far apart to make room for subsequent testing.

[0080] The supporting component 400 includes a connecting bracket 401 and a linear module 106 that drives the connecting bracket 401 to move in the vertical direction.

[0081] The connecting bracket 401 is provided with a rotating seat 403 with its axis arranged vertically and a motor 402 for driving the rotating seat 403 to rotate.

[0082] A rotating disk 404 is coaxially mounted inside the rotating base 403.

[0083] The rotating base 403 is also equipped with a clamping unit and a motor 405 for driving the rotating disk 404 to rotate. Several clamping units are arranged in an array along the circumference of the rotating base 403.

[0084] Specifically, the clamping unit includes a guide rod 406 extending radially along the rotating base 403, a slider 407 slidably disposed on the guide rod 406, a pin 408 disposed on the upper surface of the slider 407, the pin 408 and the linkage hole 4041 disposed on the rotating disk 404 forming a sliding guide engagement, and when the rotating disk 404 rotates, the slider 407 can move on the guide rod 406 through the engagement of the linkage hole 4041 and the pin 408, so that the slider 407 moves closer to or away from the axis of the rotating base 403.

[0085] A support rod 409 is provided at the upper end of the pin 408, and a clamping roller 410 is provided on the upper surface of the support rod 409. The clamping roller 410 is located above the rotating seat 403, and the rotating seat 403 is provided with a clearance hole 4031 for avoiding the clamping roller 410.

[0086] A method for detecting the viscosity of cosmetics using the aforementioned cosmetic viscosity detection device includes the following steps:

[0087] Step 1: Place the instrument stand 100 on the experimental table and place the test cup containing the cosmetic sample on the upper surface of the rotating seat 403;

[0088] Step 2: The rotating disk 404 is driven to rotate by motor 3 405, which causes all the clamping rollers 410 to move closer to each other, and the detection cup is self-centering and clamped on the rotating seat 403.

[0089] Step 3: The experimenter moves the mounting bracket 101, causing the mounting bracket 101 to swing along with the test cup. At the same time, the rotating seat 403 is driven to rotate by the motor 402, and the rotating seat 403 rotates along with the test cup.

[0090] Its technical advantage is that the swing of the mounting bracket 101 can swing the test cup together. The swing includes swinging along the axis of the connecting shaft 1 204 and swinging along the axis of the connecting shaft 2 205. Combined with the rotation of the rotating seat 403 carrying the test cup, it can effectively and quickly homogenize the cosmetic sample in the test cup, which can further improve the uniformity of the sample, thereby improving the accuracy of the final test results.

[0091] Step 4: Hydraulic medium is sent into the brake stop pipe 208 through hydraulic cylinder 201, so that the rubber protrusion 2091 on the brake block 209 abuts against the brake disc 1 206 or the brake disc 207. As the oil supply of hydraulic cylinder 201 gradually increases, the friction between the rubber protrusion 2091 and the brake disc 1 206 or the brake disc 207 increases synchronously, thereby achieving the purpose of limiting the swing amplitude of the mounting bracket 101.

[0092] When the swing amplitude of the mounting bracket 101 decreases, the hydraulic cylinder 201 stops supplying oil, and the rubber protrusion 2091 disengages from the brake disc 1 206 or brake disc 207.

[0093] After waiting for a preset time, the mounting bracket 101 stops swaying and stabilizes. At this time, the hydraulic cylinder 201 continues to supply oil, which clamps the brake disc 1 206 and the brake disc 207 through the brake block 209, thereby keeping the mounting bracket 101 in its current state.

[0094] Its technical advantages are as follows: First, the swaying of brake disc 1 (206) and brake disc 2 (207) is hindered, allowing them to quickly stabilize. Then, the swaying amplitude of the mounting bracket 101 is removed. At this point, the swaying amplitude of the mounting bracket 101 is low, and it can stabilize after a short time. Then, the mounting bracket 101 is limited and fixed, which can quickly stabilize the mounting bracket 101 and keep the rotor 102 and the center line of the detection cup vertical. On the one hand, rapid stabilization can prevent the cosmetic sample from delaminating due to prolonged static time. On the other hand, keeping the rotor 102 and the detection cup vertical can further improve the accuracy of the detection results. Furthermore, even if the swaying amplitude in step three is large, it can quickly stabilize, improving detection efficiency. Finally, it can adapt to complex laboratory testing environments and quickly and automatically level the detection device.

[0095] Step 5: Drive the support member 400 and the detection cup upward through the linear module 2 106, so that the rotor 102 extends into the detection cup;

[0096] Step 6: Drive the rotor 102 to rotate using the drive source 103 to detect the viscosity of the cosmetic sample.

[0097] In a preferred embodiment, a level can be set on the rotating base 403 (a level can be directly placed on the rotating base; the existing technology is to place the level on an object to observe whether it is level, so the specific method of setting the level on the rotating base will not be described here). The technical advantage is that after the test is completed and the test cup is removed, the experimenter can observe whether the level is level, thus avoiding the problem of levelness caused by improper operation of the equipment during the test, which may be overlooked by the experimenter and lead to inaccurate test results.

[0098] The above embodiments are only used to illustrate the detailed solutions of the present invention. The present invention is not limited to the above detailed solutions, that is, it does not mean that the present invention must rely on the above detailed solutions to be implemented. Those skilled in the art should understand that any improvements to the present invention, equivalent substitutions of the raw materials of the product of the present invention, addition of auxiliary components, selection of specific methods, etc., are all within the protection scope and disclosure scope of the present invention.
