[0023] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0024] The terms "top surface", "bottom surface" and "underside surface" are based on the normal use state of the friction coefficient tester and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0025] like Figure 1 and 2 As shown, an antibacterial filtering non-woven fabric detection device includes a body 1 with a traction mechanism 2 and a fixed clamp 5 on the top surface, the traction mechanism 2 is provided with a sensor 3, the detection end of the sensor 3 is connected to a slider 4, a heating table 103 is provided on the top surface of the body 1, and a movable clamp 6 is also provided on the top surface of the body 1 to slide relative to the fixed clamp 5, and a sliding seat 604 is slidably connected to the heating table 103; when sliding, the movable clamp 6 is used to flatten the non-woven fabric on the heating table 103; when stationary, the movable clamp 6 and the fixed clamp 5 respectively fix the two ends of the non-woven fabric to keep the non-woven fabric in a flattened state.

[0026] In the above-mentioned friction coefficient tester, the traction mechanism 2 can be composed of a motor, a worm and a moving seat, and the motor provides power to drive the moving seat to move through the worm, thereby pulling the slider 4 to move; when in use, the non-woven fabric is respectively fixed on the slider 4 and the body 1, and the traction mechanism 2 pulls the slider 4 to move, so that the two parts of the non-woven fabric rub against each other, and the friction force is detected by the sensor 3 at the same time, and finally the friction coefficient of the non-woven fabric is detected.

[0027] In the above-mentioned friction coefficient tester, a mobile clamp 6 is also provided. When in use, one end of the non-woven fabric is first fixed by the fixed clamp 5, and then the mobile clamp 6 is moved. In this process, the wrinkled parts of the non-woven fabric are smoothed by the mobile clamp; when the mobile clamp 6 moves into place and stops moving, the mobile clamp can fix the other end of the non-woven fabric on the machine body 1. By fixing the non-woven fabric at both ends at the same time, the stability of the non-woven fabric fixation can be improved, so that the non-woven fabric can be kept in a flat state, and then in the subsequent detection process, the detection accuracy of the friction coefficient tester is improved; the heating table 103 provided on the machine body 1 can be used to lay the non-woven fabric. By heating the non-woven fabric by the heating table 103, the mobile clamp 6 can better smooth the wrinkles of the non-woven fabric, further improving the detection accuracy of the friction coefficient tester; and by controlling the temperature of the heating table 103, the temperature of the non-woven fabric during detection can be effectively controlled, reducing the influence of temperature changes on the friction coefficient detection of the non-woven fabric, and further improving the detection accuracy of the friction coefficient tester.

[0028] A further improvement is, Figure 2 and 3 As shown, the fixing clamp 5 includes a fixing clamp 503 and an anti-skid pad 502 disposed on the side of the fixing clamp 503 adjacent to the machine body 1. The machine body 1 is provided with a threaded hole 102, and the fixing clamp 503 is threadedly connected to the threaded hole 102 via a fixing bolt 501. When the above-mentioned friction coefficient tester is used, the fixing clamp 503 can be loosened by loosening the fixing bolt 501, and then one side of the non-woven fabric is placed between the fixing clamp 503 and the top surface of the machine body 1, and then the fixing bolt 501 is tightened, and the non-woven fabric is clamped from both sides by the fixing clamp 503 and the machine body 1 to achieve the fixing of the non-woven fabric. The anti-skid pad 502 can increase the friction between the fixing clamp 503 and the non-woven fabric, and improve the firmness of the fixing of the non-woven fabric.

[0029] A further improvement is, Figure 4-6As shown, the movable clamp 6 includes a movable clamp 601, and the side of the movable clamp 601 facing away from the fixed clamp 5 is connected to a lower pressure strip 605 through an arc transition. The distance between the lower pressure strip 605 and the heating table 103 gradually decreases toward the movable clamp 601, and both ends of the movable clamp 601 are connected to the machine body 1 through a sliding unit. When the friction coefficient tester is in use, the movable clamp 601 is slid on the top surface of the machine body 1 through the sliding unit, and the sides of the movable clamp 601 and the lower pressure strip 605 adjacent to the machine body 1 are both smooth planes; the non-woven fabric is located between the movable clamp 601 and the heating table 103, and during the movement of the movable clamp 601, the non-woven fabric is squeezed by the movable clamp 601, so that the wrinkles on the non-woven fabric are flattened, so that the non-woven fabric is evenly spread on the top surface of the heating table 103, thereby reducing the wrinkles on the non-woven fabric. When the movable splint 601 moves to the edge of the non-woven fabric, it stops moving. At this time, the movable splint 601 and the body 1 clamp the non-woven fabric from both sides to fix the non-woven fabric and improve the accuracy of the friction coefficient tester in detecting the friction coefficient of the non-woven fabric; the arc transition between the lower pressing strip 605 and the movable splint 601 can improve the smoothness of the connection between the two. When the movable splint 601 moves, the lower pressing strip 605 can guide the non-woven fabric, making the movable splint 601 move more smoothly.

[0030] A further improvement is, Figure 2 and 5 As shown, the sliding unit includes a sliding groove 101 opened on the top surface of the body 1, a sliding seat 604 slidably matched inside the sliding groove 101, and a guide column 6041 fixedly connected to the sliding seat 604 perpendicular to the top surface of the body 1, a first guide hole 6012 slidably matched with the guide column 6041 is opened at the end of the movable splint 601, and a threaded sleeve 603 is threadedly connected to the end of the guide column 6041 away from the sliding seat 604. Two slide grooves 101 are arranged on the body 1, and sliding seats 604 are arranged inside the two slide grooves 101, so that the two ends of the movable splint 601 are respectively connected through the sliding seats 604, thereby improving the stability of the movable splint 601; an external thread threadedly connected to the threaded sleeve 603 is arranged on the guide column 6041. When in use, the threaded sleeve 603 can be controlled to move axially along the guide column 6041 by screwing the threaded sleeve 603, thereby controlling the pressure generated by the threaded sleeve 603 on the movable splint 601; when the movable splint 601 needs to move, the threaded sleeve 603 can be screwed to reduce the pressure between the movable splint 601 and the non-woven fabric, so that the movable splint 601 can move smoothly and have a flattening effect; when the movable splint 601 is moved into place, the threaded sleeve 603 can be tightened, so that the movable splint 601 clamps the non-woven fabric to achieve fixation of the non-woven fabric.

[0031] A further improvement is, Figure 5As shown, an elastic collar 6022 is provided between the threaded sleeve 603 and the movable clamping plate 601, and the guide column 6041 is provided through the elastic collar 6022. The provision of the elastic collar 6022 can play an effective buffering role, so that when the movable clamping plate 601 moves, a certain pressure is always maintained between the movable clamping plate 601 and the non-woven fabric, thereby improving the flattening effect on the non-woven fabric; and the friction force of the elastic collar 6022 can also reinforce the threaded sleeve 603 to prevent it from loosening.

[0032] Since the side of the movable clamping plate 601 in contact with the non-woven fabric is a smooth plane, the friction between the two is small and the fixing effect cannot be guaranteed.

[0033] To address the above problems, further improvements are as follows: Figure 5 and 6 As shown, the movable splint 601 is also provided with a locking piece for fixing the non-woven fabric; the locking piece includes a lifting plate 602 with second guide holes 6023 at both ends, the guide column 6041 is slidably matched with the second guide hole 6023, the elastic ring 6022 is located between the lifting plate 602 and the movable splint 601, and the lifting plate 602 is provided with an anti-slip strip 6021 on the side of the heating table 103.

[0034] In the above-mentioned friction coefficient tester, when the movable splint 601 is in the moving state, the supporting force of the elastic ring 6022 props up the lifting plate 602, so that the anti-slip strip 6021 is separated from the non-woven fabric, so that the movable splint 601 can move normally; when it is moved into place, the lifting plate 602 is pressed down by the threaded sleeve 603, so that the anti-slip strip 6021 is tightly abutted against the non-woven fabric, thereby increasing the friction between the non-woven fabric and the lifting plate 602. Since the lifting plate 602 is connected to the movable splint 601, the friction between the movable splint 601 and the non-woven fabric is correspondingly increased, thereby improving the firmness of the movable splint 601 to fix the non-woven fabric, and finally improving the accuracy of the friction coefficient tester in detecting the friction coefficient of the non-woven fabric.

[0035] A further improvement is, Figure 5 The movable clamping plate 601 is provided with a slot 6011 through which the anti-slip strip 6021 can pass. The slot 6011 is provided so that the anti-slip strip 6021 can pass through the movable clamping plate 601 and contact the non-woven fabric. The mutual limitation between the slot 6011 and the anti-slip strip 6021 can improve the stability of the connection between the two, thereby improving the firmness of the movable clamping plate 601 to fix the non-woven fabric; and the slot 6011 can be used to accommodate part of the anti-slip strip 6024, thereby reducing the space occupied by the device and achieving the protection of the anti-slip strip 6024.

[0036] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
