The front and rear positioning blocks 144 center the winding drum, which makes the left and right winding drums correspond to each other, which can prevent the decorative cloth from being tilted during the winding process and affecting the detection, thereby ensuring the normal detection of the decorative cloth. At the same time, the movable bar 141 also drives the front and rear movable frames 7 to move in the direction of approaching each other, and the movable frame 7 drives the front and rear fixed splints 10 and the movable splint 11 to move in the direction of approaching each other through the movable seat 8 and the n-shaped rod 9. , so that the fixed splint 10 and the movable splint 11 can adapt to the width of the decorative cloth, the two-way cylinder 145 is closed, and then the head end of the decorative cloth is pulled through the movable splint 11 and the fixed splint 10 and fixed on the right winding drum, and then the electric drive block 133 is started to move. Since the elastic force of the connecting spring 132 is less than the return spring Ⅰ81, the electric drive block 133 moves and first pushes the wedge block 13 to move upward, and the wedge block 13 moves upward and drives the waist-shaped hole plate 131 to move upward through the vertical rod 1301, and the waist-shaped hole plate 131 moves upward and drives the connecting rod 12 to move upward, and the connecting rod 12 drives the outer end of the movable splint 11 to swing upward, and the outer end of the movable splint 11 swings upward so that the inner end swings downward, and the movable splint 11 swings downward and contacts the decorative cloth, and the movable splint 11 Cooperating with the fixed splint 10, the front and rear sides of the decorative cloth are clamped and fixed, and the movable splint 11 stops swinging downward, and the movable splint 11 stops the connecting rod 12 from moving upward, which also stops the wedge block 13 from moving upward. At this time, the electric drive block 133 continues to move to push the front and rear movable seats 8 to move away from each other. The return spring Ⅰ81 is compressed, and the movable seat 8 drives the front and rear fixed splints 10 and the movable splint 11 to move away from each other through the n-shaped rod 9. The front and rear fixed splints 10 and the movable splint 11 also pull the front and rear sides of the decorative cloth toward each other, making the decorative cloth taut. The electric drive block 133 is turned off, and the single-rod cylinder 15 is started again.

The displacement sensor 61 detects the deformation range of the decorative cloth, thereby transmitting the detected data to the terminal. When the structural strength test of a part of the decorative cloth is completed, the electric hammer 6 is started to move upward to reset and disengage from the decorative cloth, and then the single-rod cylinder 15 is started with The movable frame 151 moves upward, and the movable frame 151 drives the pressure plate 154 to move upward and disengage from the decorative cloth, closes the single-rod cylinder 15, and then starts the electric drive block 133 to move and reset. Due to the action of the reset spring Ⅰ81, the front and rear movable seats 8 move toward each other and reset, so that the fixed splint 10 and the movable splint 11 move toward each other and reset. Subsequently, due to the action of the connecting spring 132, the waist-shaped hole plate 131 moves downward and resets, and the vertical rod 1301 drives the wedge block 13 to move downward and reset, and the waist-shaped hole plate 131 also moves through the connecting rod 12 The movable clamping plate 11 is driven to swing upward and reset to loosen the decorative cloth.

The left take-up drum rotates to release the decorative cloth, while the right take-up drum rotates to reel in the tested decorative cloth. The guide roller 155 and the support roller 156 guide and level the decorative cloth. When the lower part of the decorative cloth moves to the testing area, the electric spline shaft 3 is closed. Following the above operation, the four sides of the decorative cloth are clamped again and tensioned for structural strength testing. This prevents the decorative cloth from being loose and affecting the test, thereby improving the accuracy of the structural strength test. After the structural strength test of a roll of decorative cloth is completed, the two-way cylinder 145 is activated to drive the front and rear movable bars 141 to move away from each other and reset, so that the positioning block 144 is reset and disengaged from the take-up drum, and the take-up drum is removed from the electric spline shaft 3.

The movement drives the pull wire 166 to move downward, and then the mounting plate 152 stops moving downward, and the mounting plate 152 stops driving the magnetic block 168 to move downward, and the magnetic block 168 stops the pull wire 166 from moving downward, and the guide rod 163 continues to move downward to guide and squeeze the pull wire 166, so that the pull wire 166 drives the slide plate 165 to move backward, and the return spring II 164 is compressed, and the slide plate 165 moves backward to drive the hollow tube 161 to move backward, and the hollow tube 161 drives the chalk 162 backward. When the hollow tube 161 moves backward to the maximum stroke in the slotted hole plate 16, the hollow tube 161 stops moving backward, and the pull wire 166 stops moving backward through the slide 165. Then the guide rod 163 continues to move downward and drives the iron block 167 downward through the pull wire 166. The iron block 167 moves downward and is out of contact with the magnetic block 168. Due to the action of the reset spring II 164, the slide 165 moves forward to drive the hollow tube 161 forward. The hollow tube 161 The chalk 162 moves forward, pressing plate 154 firmly holds the fabric in place. Chalk 162 contacts the fabric and moves forward, marking the inspection area. Slide plate 165 then moves forward, driving pull cord 166 forward and back to its original position. This resets pull cord 166, which in turn drives iron block 167 back to its original position via guide rod 163. The raised portion of guide rod 163 supports and limits iron block 167. The electric hammer 6 then activates to test the fabric's structural strength. Once the fabric's structural strength test is complete, the operator can more clearly identify the inspection area based on the location of the marked line. When the pressing plate 154 moves upward to reset, the pressing plate 154 drives the iron block 167 upward to reset through the guide rod 163. The iron block 167 resets and magnetically contacts the magnet 168. As the chalk 162 is used continuously, the chalk 162 moves so that it is difficult to contact the decorative cloth to draw lines. At this time, the motor 169 is started to drive the sponge wheel 1610 to reverse. The sponge wheel 1610 reverses and drives the chalk 162 downward. When the chalk 162 moves downward to the designated position, the motor 169 is turned off and the sponge wheel 1610 stops driving the chalk 162 downward. In this way, the detection area of ​​the decorative cloth is prevented from being unclear, making it difficult for the operator to view, thereby facilitating the operator's inspection of the decorative cloth.

[0037] See also Figure 11As shown, the structural strength detection device for decorative cloth production also includes a support plate 17 and an air jet pipe 18. The support plate 17 is symmetrically fixed to the front and back of the left top of the base 1. The support plate 17 is located on the right side of the vertical plate 2 on the left. The air jet pipe 18 is fixed between the upper parts of the front and rear support plates 17. The air outlet of the air jet pipe 18 faces the lower left. The air jet pipe 18 can spray air on the decorative cloth to remove impurities.

[0038] Initially, the air jet tube 18 is connected to an external air pump. Once the decorative fabric is in place, the pump is activated, pumping air into the air jet tube 18. This air is then sprayed onto the fabric, removing impurities. After the impurities are removed, the fabric is moved to the testing area for structural strength testing. Once the structural strength test is complete, the pump is turned off, and the air jet tube 18 stops spraying air. This prevents debris from remaining on the fabric and affecting subsequent testing, further ensuring the accuracy of the fabric testing.
