[0042] A roller 3 rotatably arranged on the vertical support plate 2.

[0044] A plurality of arc-shaped slots 4 are circumferentially arranged on the arc surface of the roller 3, a limiting strip 5 is fixedly arranged in the arc-shaped slot 4, and the outer portion of the limiting strip 5 and the inner wall of the arc-shaped slot 4 form a cloth passing groove. After the knitted fabric passes through each cloth passing groove in sequence, the plurality of cloth passing grooves separate the knitted fabric outside the roller 3 into a plurality of detection areas.

[0045] A cloth head fixing part 6 arranged on the roller 3, the cloth head fixing part 6 is used for fixing the two ends of the knitted fabric and making the knitted fabric taut.

[0046] A plurality of contrast cloth fixing parts 8 are circumferentially arranged on the vertical support plate 2, the contrast cloth fixing parts 8 are used for fixing the contrast cloth and making the contrast cloth and the opposite surface of the knitted fabric abut each other.

[0047] As shown in Figures 1 to 3 The roller 3 and the contrast cloth fixing part 8 are located on the same vertical plane of the vertical support plate 2, and the roller 3 is located between all the contrast cloth fixing parts 8.

[0048] The detection area corresponds to the control cloth fixing part 8, and the gap between the limiting strip 5 and the two control cloth fixing parts 8 corresponds.

[0049] In this way, after a piece of knitted cloth is fixed on the arc surface of the roller 3, different parts of the same piece of knitted cloth can correspond to and closely fit different control cloths, so that the friction detection results of the same piece of knitted cloth with different cloths can be detected at the same time, the detection error is reduced, and the detection accuracy is improved.

[0050] As shown in Figure 2 and Figure 3 , the control cloth fixing part 8 comprises:

[0051] The outer support 81 is fixed at the boundary of the vertical support plate 2.

[0052] The outer support 81 is fixed at the boundary of the vertical support plate 2.

[0053] The pressing cloth strip 85 is inserted into the pressing cloth groove 82 provided on the outer support 81.

[0054] The screw rod 84 is arranged between the pressing cloth strip 85 and the outer support 83.

[0055] One end of the screw rod 84 is rotatably arranged on the pressing cloth strip 85, and the other end of the screw rod 84 is threadedly arranged on the outer support 83.

[0056] In this way, the control cloth can be easily sleeved on the outer support 81 by simple sleeving, and the screw rod 84 can be twisted to push the pressing cloth strip 85 towards the pressing cloth groove 82, so as to tightly fix the end of the control cloth arranged in the pressing cloth groove 82. The operation is simple and efficient, and a plurality of different control cloths can be uniformly distributed on the outer part of the roller 3, so that different positions of the same piece of knitted cloth can be in contact with different control cloths, so as to simultaneously complete the friction detection of the knitted cloth and a plurality of different control cloths, and improve the friction detection accuracy of the knitted cloth and different control cloths.

[0057] As shown in Figure 2 and Figure 3 , the cloth head fixing part 6 comprises a receiving groove 61 arranged radially on the arc surface of the roller 3, a licker-in 62 is arranged in the receiving groove 61 in a relative rotating manner, a plurality of licker-in spikes are arranged on the arc surface of the licker-in 62, a tightening member 63 for driving the two licker-ins 62 to rotate in opposite directions comprises a transmission tooth fixed to one end of the licker-in 62, the tooth surfaces of the two transmission teeth are engaged, one end of one of the licker-ins 62 is provided with a round handle, a limiting pin is inserted into the round handle, a plurality of insertion holes are arranged circumferentially on the vertical support plate 2, and the insertion holes are matched with one end of the limiting pin. When the round handle cannot be rotated during the operation of fixing the ends of the knitted cloth, one end of the limiting pin can be inserted into the corresponding insertion hole, so that the round handle and the two ends of the knitted cloth can be fixed.

[0058] Thus, after the end of the knitted fabric is attached to the arc surface of the taker-in roller 62, the two taker-in rollers 62 are driven to rotate in opposite directions synchronously by the tightening member 63, so that the taker-in spikes are inserted into the knitted fabric, the end of the knitted fabric is fixed, and the knitted fabric is gradually pulled tight along with the winding of the taker-in roller 62 until the knitted fabric is tightly attached to the arc surface of the drum 3. Thus, the knitted fabric is attached to different reference fabrics fixed on the outer supports 81, so that different reference fabrics can be rubbed with different positions of the same knitted fabric at the same time, reducing the error of the rubbing detection and improving the accuracy of the rubbing detection result.

[0059] As shown in Figure 3 and Figure 4 , the reciprocating driving part 7 comprises:

[0060] The limiting guide rail 75 is fixed on the vertical support plate 2.

[0061] The toothed shaft 77 is rotatably arranged between the two vertical surfaces of the vertical support plate 2, and one end of the toothed shaft 77 is fixed on one end surface of the drum 3.

[0062] The rack 76 is slidably arranged between the other end of the toothed shaft 77 and the limiting guide rail 75, and the tooth surface of the rack 76 is engaged with the tooth surface of the other end of the toothed shaft 77.

[0063] The motor seat 71 is fixed on the vertical support plate 2.

[0064] The vertical support 72 is fixed on the top of the motor seat 71.

[0065] The toothed disc 73 is rotatably arranged on the vertical support 72.

[0066] The driving member 74 is used to drive the toothed disc 73 to rotate.

[0067] The connecting arm 78 is hingedly connected between the toothed disc 73 and the rack 76.

[0068] The driving member 74 comprises a driving motor fixed on the top of the motor seat 71 and a spur gear arranged on the output end of the driving motor, and the tooth surface of the spur gear is engaged with the tooth surface of the toothed disc 73.

[0069] In this way, the driving motor continuously drives the gear disc 73 to rotate in the same direction, so that the gear disc 73 pulls one end of the connecting arm 78 to rotate synchronously in the circumferential direction, the connecting arm 78, the limiting guide rail 75 and the toothed shaft 77 limit and guide the rack 76, the circumferential rotation of the gear disc 73 is converted into the linear reciprocating motion of the rack 76 in the transverse direction, and the power is transmitted to the roller 3 through the toothed shaft 77, so that the roller 3 is deflected by a certain angle clockwise and then deflected counterclockwise to the initial position, and then continues to be deflected counterclockwise by a certain angle, so that the roller 3 is deflected by the same angle to both sides of the initial position. In this way, the gear disc 73 can drive the roller 3 to reciprocate once every rotation, and this process is repeated until the friction detection result is obtained.

[0070] Working principle: first, the end of the strip-shaped knitted fabric to be detected is fitted to the arc surface of the roller 3 from the outside of the storage groove 61, and then alternately passes between the outer support 81 and the roller 3 and between the limiting strip 5 and the arc-shaped slot 4, and finally the two ends of the knitted fabric to be detected are respectively fitted to the opposite surfaces of the two taker-in rollers 62, then the two taker-in rollers 62 are driven to rotate in opposite directions by controlling the tightening member 63 and winding the end of the knitted fabric to be detected, until the knitted fabric is tightly fitted to the arc surface of the roller 3. After the knitted fabric is fixed, the control fabrics of different materials are sleeved outside the different outer supports 81 and are tightly fitted, then the two ends of the control fabric are placed in the pressing groove 82, and the screw rod 84 is twisted to push the pressing strip 85 towards the inside of the pressing groove 82, until the ends of the control fabric are tightly fixed between the two. After all the control fabrics are fixed, the reciprocating drive part 7 is started to drive the roller 3 to deflect by a certain angle clockwise and then deflect by a certain angle counterclockwise, and this process is repeated. The included angle between the deflection directions of the roller 3 changes oppositely each time, and the size of the included angle is twice the interval angle between the two adjacent outer supports 81. In this way, the same knitted fabric can be simultaneously subjected to friction detection with several different control fabrics, so that the knitted fabric and the several different control fabrics are subjected to friction detection under the same conditions, greatly reducing the range of operation influence error and improving the precision of the friction detection result of the knitted fabric and the different material fabrics.
