Technical Field
[0001] This invention relates to the field of abrasion resistance testing equipment, specifically to abrasion resistance testing equipment for stainless steel thermos cup coatings. Background Technology
[0002] A thermos is a portable container designed specifically to maintain the temperature of its internal liquid. Its core insulation principle is based on the heat transfer blocking mechanism. This is usually achieved by setting a vacuum layer between the inner liner and the outer shell, filling it with heat insulation material, or using an inner liner material with a high thermal conductivity and low thermal conductivity. This reduces the heat exchange between the internal liquid and the external environment in three dimensions: conduction, convection, and radiation. As a result, the temperature of hot water, cold water, beverages, and other contents can be kept stable for a long time. The thermos also has practical features such as leak-proof and drop-resistant properties. It is widely used in daily office work, home life, outdoor travel, commuting, and sports, providing users with a comfortable drinking experience anytime, anywhere.
[0003] The stainless steel thermos cup coating abrasion resistance testing equipment is a testing device specifically designed to evaluate the abrasion resistance performance of the inner liner or outer surface coating of stainless steel thermos cups. Its core function is to quantitatively or qualitatively test the degree of wear, adhesion, and integrity of the coating under repeated friction by simulating friction and scratching scenarios in daily use. This determines whether the coating meets the abrasion resistance requirements for long-term use of thermos cups, providing technical support for the quality control and performance evaluation of thermos cup coatings.
[0004] However, existing equipment for testing the abrasion resistance of stainless steel thermos cup coatings has the following shortcomings: Currently available stainless steel thermos cup coating wear resistance testing equipment uses bolt-locking clamps, requiring manual leveling and tightening. Furthermore, different cup diameters and shapes necessitate clamp replacement and repositioning, hindering rapid switching, impacting batch testing efficiency, and increasing overall testing time.
[0005] Therefore, we propose a device for testing the wear resistance of stainless steel thermos cup coatings to address the problems mentioned above. Summary of the Invention
[0006] The purpose of this invention is to provide a device for testing the wear resistance of stainless steel thermos cup coatings. During testing, the thermos cup is first placed on a rack. An electric telescopic rod drives a first friction head to push the cup towards an inner support plate and position it. If the inner support plate does not extend due to differences in cup size, a linear motor drives a support bracket to move, cooperating with a reverse thrust to position the cup opening. Subsequently, a second stepper motor drives a threaded rod to drive an inner support block, pushing the inner support plate to support and fix the cup body via a contact plate. The first stepper motor drives the cup body to rotate, synchronously rubbing against the first and second friction heads to obtain wear resistance data at multiple locations. Simultaneously, the cup body rotates and contacts... The device delivers a striking hammer head with elastic impact, simultaneously testing impact resistance. Its internal support and multi-spring elastic buffer adapt to different sizes and shapes of cups, eliminating the need to change clamps and reducing manual adjustment and loading / unloading work. Integrating wear resistance and impact resistance dual testing functions, it avoids secondary errors with a single clamping, improving data correlation. The linear motor and electric telescopic rod work together to quickly adapt to different cup specifications, enhancing the continuity of batch testing. The even distribution of clamping force and friction contact design ensure accurate test data, significantly reducing testing time and manpower, and greatly improving batch testing efficiency.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. During the testing process, this invention involves placing the thermos cup on a rack. An electric telescopic rod drives the first friction head to push the cup towards the inner support plate, causing it to fit over the inner support plate and the contact plate. If, due to differences in cup shape or size, the inner support plate does not extend into the cup, but the cup is within the working range of the friction head, a linear motor is activated to drive the connecting slider, which in turn moves the bracket and slide towards the cup. This, combined with the reverse thrust of the first friction head, ensures the cup opening fits and is positioned against the cup opening pad. Subsequently, a second stepper motor drives the threaded rod to rotate, moving the inner support block and pushing the inner support plate outwards, thus supporting the cup through the contact plate. Once fixed, the first stepper motor drives the cup body to rotate, causing it to rub synchronously with the first and second friction heads to obtain wear resistance data at different locations. At the same time, the rotation of the cup body and the friction with the striking hammer head generate vibration, which, combined with the shock-absorbing spring and the second torsion spring, causes the hammer head to strike the outside of the cup body, simultaneously detecting the impact resistance data. In this way, manual fastening and unloading work is reduced, and the internal support fixing method is applicable to most sizes of insulated cups, avoiding the need for clamp replacement due to limitations, allowing for quick switching, improving batch testing efficiency, and reducing overall testing time and manpower input.
[0018] 2. In operation, the inner support block of this invention is driven by a threaded rod and guided by a limiting strip. Combined with the elastic buffering of the inner support plate, the first torsion spring, the tension spring, and the compression spring, it can adapt to the inner walls of insulated cups of different shapes and diameters. It can stably clamp the cups without changing to special clamps, reducing manual adjustments and improving batch changeover efficiency. Simultaneously, the tension and compression springs ensure real-time contact between the contact plate and the cup body, further enhancing clamping stability. The device integrates coating wear resistance testing and impact resistance testing. When the insulated cup rotates, it rubs synchronously with the first and second friction heads, while the striking hammer head is activated by the second torsion spring and the shock-absorbing spring. It achieves elastic impact, completing two tests in one clamping, avoiding secondary clamping errors, improving testing efficiency and data correlation. The dual elastic structure can also simulate actual non-rigid impact scenarios, avoiding unexpected damage and ensuring that the test results are consistent with the usage conditions. The support and slide are moved as a whole by a linear motor, and the position of the first friction head is adjusted by an electric telescopic rod, which can quickly adapt to thermos cups of different lengths and sizes, reduce manual operation, and improve the continuity of batch testing. The uniform transmission of clamping force and the cooperative design of the friction head and the rotating structure ensure the coaxiality of the cup body and the consistency of frictional contact, improving the accuracy of wear resistance test data.

A rotating cylinder 235 is installed on the inner side of bracket 203. A first stepper motor 209 is installed on the top of slide 206. The bottom of connecting slider 205 is installed on the top of the output end of linear motor 202. Multiple slide bars 208 are slidably connected to the inner side of slide groove 207. A rotating shaft 210 is installed on the output end of the first stepper motor 209. The rotating shaft 210 is rotatably connected to the inner side of rotating cylinder 235. A first cup mouth pad 211 is installed on the other side of rotating shaft 210. A second cup mouth pad 212 is installed on the other side of the first cup mouth pad 211. A cup-mouth inner plug 213 is installed on the other side of the cup-mouth pad 212. A second stepper motor 214 is installed on the inner side of the second cup-mouth pad 212. The output end of the second stepper motor 214 passes through the cup-mouth inner plug 213 and is equipped with a threaded rod 236. A mounting ring 215 is installed on the outer side of the cup-mouth inner plug 213. Multiple inner support plates 216 are rotatably connected to the inner side of the mounting ring 215. A first torsion spring 217 is sleeved on both sides of the inner support plate 216. One end of the first torsion spring 217 is installed on the inner side of the mounting ring 215, and the other end of the first torsion spring 217 is installed on the inner side of the inner support plate 216. A tension spring 218 is installed on the top of the inner support plate 216. A compression spring 219 is installed at the top of another part of 16. A contact plate 220 is installed at the top of the tension spring 218 and the compression spring 219. The bottom middle of the contact plate 220 is rotatably connected to the top of the other end of the inner support plate 216. An inner support groove 221 is opened on the inner side of the inner support plate 216. A limit groove 222 is opened on the inner side of the inner support plate 216. The limit groove 222 is located in the middle of the inner side of the inner support groove 221. An inner support block 223 is slidably connected to the inner side of the inner support groove 221. Multiple limit strips 224 are installed on the outer side of the inner support block 223. The limit strips 224 slide on the inner side of the limit groove 222. The inner support block 223 is threadedly connected to the threaded rod 236.
[0023] The overall effect of Embodiment 1 is as follows: When batch testing the wear resistance of stainless steel thermos cup coatings, the thermos cups to be tested are first placed on the placement rack 233. The electric telescopic rod 231 is activated to drive the first friction head 232 to push the thermos cups towards the inner support plate 216 until the thermos cups are fitted onto the inner support plate 216 and the outside of the contact plate 220. If, due to differences in the shape and size of the thermos cups, they are already within the working range of the first friction head 232 and the second friction head 234, but the inner support plate 216 has not extended into the thermos cup, it is necessary to activate... Linear motor 202 drives connecting slider 205 to slide within connecting groove 204, causing connecting groove 204 to move bracket 203 and slide 206 toward the thermos cup until inner support plate 216 extends into the thermos cup. Simultaneously, the reverse thrust of first friction head 232 causes the cup mouth to fit against first cup mouth pad 211 or second cup mouth pad 212 to achieve positioning. Then, second stepper motor 214 is started to drive threaded rod 236 to rotate. Threaded rod 236, in conjunction with limit strip 224, drives inner support block. 223 moves inward, and the inner support block 223 pushes multiple outer inner support plates 216 outward through its own shape. The inner support plates 216 drive the contact plates 220 to move towards the inner wall of the thermos cup until the multiple contact plates 220 contact the inner wall of the thermos cup and support and fix it. After the thermos cup is fixed, the first friction head 232 contacts the thermos cup body 3, and the first stepper motor 209 is started to drive the thermos cup to rotate. The rotating thermos cup rubs synchronously with the second friction head 234 at the bottom and the first friction head 232 on the outside to complete the process. The wear resistance test is conducted by using the second friction head 234 at different positions and the first friction head 232 on the outside to obtain wear resistance data at different positions of the thermos cup. At the same time, the surface of the thermos cup vibrates due to friction with the striking hammer head 230 during rotation. With the help of the shock-absorbing spring 229 and the second torsion spring 228 on the striking hammer head 230, the striking hammer head 230 strikes the outside of the thermos cup, and the impact resistance data is detected simultaneously. After the test is completed, the second stepper motor 214 is started to reverse and release the inner support clamp of the thermos cup body 3.
[0024] Example 2, according to Figure 4 - Figure 6As shown, a vertical plate 225 is installed on the top of the base 1, and a rotating groove 226 is installed on the top of the vertical plate 225. A rotating plate 227 is rotatably mounted inside the rotating groove 226. A second torsion spring 228 is fitted on both sides of the rotating plate 227. One end of the second torsion spring 228 is installed inside the rotating groove 226, and the other end of the second torsion spring 228 is installed inside the rotating plate 227. A shock-absorbing spring 229 is installed at the bottom of the rotating plate 227, and a striking hammer head 230 is installed at the bottom of the shock-absorbing spring 229. An electric telescopic rod 231 is installed at the bottom of the base 1, and a first friction head 232 is installed at the output end of the electric telescopic rod 231. Two placement racks 233 are installed on the top of the base 1, and a thermos cup body 3 is installed on the top of the two placement racks 233. Multiple second friction heads 234 are installed at the bottom of the base 1, and the multiple second friction heads 234 are located at the bottom of the thermos cup body 3. The striking hammer head 230 is located at the top of the thermos cup body 3.
[0025] The overall effect of Embodiment 2 is as follows: Through the cooperative structure of the inner support plate 216 and the inner support block 223, combined with the elastic buffering of the first torsion spring 217, tension spring 218, and compression spring 219, it adapts to the inner wall contours of thermos cups of different shapes and diameters. Stable clamping can be achieved without changing the special clamps, solving the problem of manual clamp adjustment required in traditional equipment, improving the changeover efficiency of batch testing, and integrating coating wear resistance friction testing and impact resistance testing into the same device. This is achieved by observing the interaction between the thermos cup and the inner support block 223 during the cup's rotation. The synchronous friction of the first friction head 232 and the second friction head 234, along with the elastic impact of the striking hammer head 230 under the action of the second torsion spring 228 and the shock-absorbing spring 229, achieves simultaneous detection of wear resistance and impact resistance in a single clamping operation. This avoids secondary clamping errors caused by separate equipment testing, improving detection efficiency and data correlation. The inner support block 223, driven by the threaded rod 236 and guided by the limiting strip 224, along with the elastic linkage design of the inner support plate 216, achieves uniform transmission of clamping force, ensuring coaxiality when the thermos cup is fixed. In addition to ensuring high precision and stability, the positional layout of the first friction head 232 and the second friction head 234, in conjunction with the rotation drive structure of the thermos cup, guarantees consistent frictional contact and improves the accuracy of wear resistance test data. A linear motor 202 drives the connecting slider 205 to move the bracket 203 and the slide 206 as a whole. This, combined with the electric telescopic rod 231, adjusts the position of the first friction head 232, quickly adapting to thermos cups of different lengths and sizes. This allows the inner support plate 216 to precisely extend into the cup body and complete its positioning, reducing the need for manual centering and alignment. The adjustment operation improves the continuity of the batch testing process. The striking hammer 230, combined with the shock-absorbing spring 229 and the second torsion spring 228, forms a dual elastic structure to simulate non-rigid impact scenarios in actual use. This avoids unexpected damage to the thermos cup body 3 and coating caused by rigid impacts, while ensuring that the impact resistance test results are more consistent with actual use conditions, thus improving the practicality of the test data. In addition, the tension spring 218 and the compression spring 219 work together to achieve real-time contact between the contact plate 220 and the thermos cup body 3, increasing the stability of the inner support clamping.
[0026] The working principle of the entire device is as follows: When conducting abrasion resistance tests on the coating of stainless steel thermos cups in batches, the thermos cups to be tested are first placed on the placement rack 233. Then, the electric telescopic rod 231 is activated to drive the first friction head 232 to push the thermos cup body 3 towards the inner support plate 216 until the thermos cup body 3 fits inside the inner support plate 216 and the contact plate 220. Due to the different shapes and sizes of the thermos cup bodies 3, when the thermos cup body 3 is already within the working range of the first friction head 232 and the second friction head 234, and the inner support plate 216 is not inside the thermos cup body 3, the device is activated. The linear motor 202 drives the connecting slider 205 to slide within the connecting groove 204, causing the connecting groove 204 to move the bracket 203 and the slide 206 towards the thermos cup body 3 until the inner support plate 216 is inserted into the thermos cup body 3. Simultaneously, the reverse thrust of the first friction head 232 ensures that the mouth of the thermos cup body 3 is in contact with either the first mouth pad 211 or the second mouth pad 212, thus achieving a relatively accurate position. At this point, the second stepper motor 214 is activated to rotate the threaded rod 236, causing the threaded rod 236 to engage with the limiting strip 224. The inner support block 223 is moved inward. As the inner support block 223 moves inward, it pushes the multiple outer inner support plates 216 outward according to its shape. At this time, the multiple inner support plates 216 drive their respective contact plates 220 to move towards the inner wall of the thermos cup until the multiple contact plates 220 simultaneously contact the inner wall of the thermos cup and support it, thereby fixing the thermos cup. When the thermos cup body 3 is fixed, the first friction head 232 and the thermos cup body 3 are in contact with each other. The first stepper motor 209 is started to drive the thermos cup body 3 to rotate. The rotating thermos cup body 3 and the first friction head 232 are in contact with each other. The second friction head 234 at the bottom and the first friction head 232 on the outside rub against each other simultaneously to conduct wear resistance tests. Multiple second friction heads 234 located at different positions and the first friction head 232 on the outside simultaneously obtain the wear resistance of different positions of the thermos. While the thermos rotates, its surface vibrates as it rubs against the impact hammer 230 and the thermos body 3. The shock-absorbing spring 229 and the second torsion spring 228 on the impact hammer 230 enable the impact hammer 230 to perform a striking action on the outside of the thermos body 3, thereby simultaneously detecting its impact resistance data.
