[0030] Reference Figure 1 A non-stick pan coating wear resistance tester includes a frame 1, on which a reciprocating drive mechanism 2, a pressurized rotary friction mechanism 3, and a pot loading and unloading mechanism 4 are arranged; the pressurized rotary friction mechanism 3 is two, respectively located on both sides of a supporting profile 23, and the pot loading and unloading mechanism 4 corresponds to the position of the pressurized rotary friction mechanism 3. This design allows the product to test two pans at the same time, making it easier to compare the quality of non-stick pan coatings of different brands, and the test efficiency is higher, and it can more intuitively show customers the differences in the wear resistance of non-stick pan coatings of different manufacturers and brands.

[0031] Reference Figure 2The reciprocating drive mechanism 2 includes a turntable 25 driven by a drive motor 24, a connecting rod 26 is movably connected to the turntable 25 at a non-central position, and the other end of the connecting rod 26 is movably installed in a slide groove 231 of a support profile 23. The frame 1 is provided with front and rear support blocks 11 and 12, and a guide rod 21 is installed between the front and rear support blocks 11 and 12. A slider 22 is movably installed on the guide rod 21, and the slider 22 is fixedly installed on the support profile 23. The drive motor 24 is a stepping motor. When the stepping motor drives the turntable 25 to rotate, the slider 22 is driven to make reciprocating linear motion in the guide rod 21 through the connecting rod 26.

[0032] In order to facilitate the adjustment of the reciprocating stroke of the slider 22, a T-slot 251 is provided on the rotating disk 25, and a T-bolt 252 can be fixedly installed at any position on the T-slot 251, and one end of the connecting rod 26 is movably installed on the T-bolt 252; in addition, the connecting rod 26 is a telescopic connecting rod, and the length of the connecting rod 26 can be adjusted at will. Therefore, by adjusting the distance of the T-bolt 252 relative to the center of the rotating disk 25 and the length of the connecting rod 26, the reciprocating stroke of the slider 22 can be adjusted.

[0033] Reference Figure 3 , 4 5. The pressurized rotating friction mechanism includes a slide 31 fixed on the supporting profile 23. For easy installation, the slide 31 is fixed on the supporting profile 23 by a locking handle 311. The slide 31 and the supporting profile 23 form a sliding fit. After adjusting the appropriate position, the relative position of the two can be fixed by locking the locking handle 311. The slide 31 is provided with a driving wheel 33 driven by a motor 32. The motor 32 is a stepping motor. The driving wheel 33 drives a driven wheel 35 through a synchronous belt 34. The driven wheel 35 drives a rotating shaft 36 arranged in the slide 31 to rotate. In order to ensure that the rotating shaft 36 rotates more smoothly, a bearing is arranged between the slide 31 and the rotating shaft 36. The lower end of the rotating shaft 36 is connected to a friction material 37 through a connecting flange 361. The friction material 37 can be a scouring pad or a wire brush. When the friction material 37 is a scouring pad, a Velcro can be provided between the connecting flange 361 and the scouring pad to facilitate the quick replacement of the scouring pad; when the friction material 37 can be a wire brush, a circular serrated structure can be used between the connecting flange 361 and the wire brush to ensure that the wire brush is not easy to fall off and can be quickly replaced.

[0034] In order to facilitate the transmission of power by the rotating shaft 36, the driven wheel 35 and the rotating shaft 36 are connected by a key. For example, the driven wheel 35 is installed on a rotating sleeve with a key, and the rotating shaft 36 with a keyway is installed in the rotating sleeve with a key. The rotating shaft 36 with a keyway and the rotating sleeve with a keyway adopt a sliding fit, and can rely on the key to transmit torque, so that the rotating shaft 36 with the keyway can move up and down and rotate. When the stepper motor drives the driving wheel 33 to rotate, the synchronous belt 34 drives the driven wheel 35 to rotate, thereby driving the scouring pad or wire brush installed at the lower end of the rotating shaft 36 with the keyway to rotate.

[0035] The upper end of the rotating shaft 36 is sleeved with a weight 38 , which can be added, removed or replaced according to test requirements. A fixing nut 39 for locking the weight 38 is provided at the top of the rotating shaft 36 to facilitate quick replacement and locking of the weight 38 .

[0036] Reference Figure 6 The pot loading and unloading mechanism 4 includes a positioning seat 41 for loading and unloading pots located on both sides of the frame 1, and the positioning seat 41 corresponds to the position of the pressurized rotating friction mechanism 3. When the pot is made of steel, the pot is fixed by an electromagnet installed under the steel bottom plate. When the pot is made of steel, the positioning seat 41 is a magnetic pot positioning mold; when the pot is not made of steel and cannot be fixed by an electromagnet, a plurality of magnetic seats with V-shaped bayonet holes are used to block and position the pot.

[0037] In addition, this product can also be equipped with an electronic control system. Through PLC program design, parameters can be set, such as the speed of the motor, the number of reciprocating movements of the scouring pad or wire brush per minute or hour, the cumulative number of times, etc.

[0038] The design drives the pressurized rotary friction mechanism 3 to perform linear reciprocating motion through the reciprocating drive mechanism 2, and the pressurized rotary friction mechanism 3 performs rotary motion at the same time, thereby simulating the linear and rotary mixed friction of the non-stick pan coating by human hands. This product can test two pans at the same time, making it easier to compare the quality of non-stick pan coatings of different brands, and the test efficiency is higher, and it can more intuitively show customers the differences in the wear resistance of non-stick pan coatings from different manufacturers and brands.

[0039] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
