[0031] Embodiment 1:

[0032] like Figure 1-4 As shown, a cutting and flattening device for isolation gowns comprises a pinch roller group 10, a stretching roller group 20 and a first guide roller 60. The stretching roller group 20 is installed above the pinch roller group 10, and the first guide roller 60 is located on the incoming material side and on the lower side of the stretching roller group 20. The cloth 70 on the incoming material side passes through a guide roller 60 and then bypasses from the upper side of the stretching roller group 20, and then the cloth 70 enters the pinch roller group 10, and then the cloth 70 is pulled from the lower side of the pinch roller group 10 to the outgoing material side. When the cloth passes through the stretching roller group 20, due to the guidance of the first guide roller 60, the cloth and the stretching roller group 20 have a larger contact area, thereby achieving the stretching of the cloth wrinkles. In addition, the cloth 70 is guided by the first guide roller 60, and the cloth 70 is more stable in shape in the section between the first guide roller 60 and the stretching roller group 20, and the cloth will not bounce during the traction process in this section, thereby improving the stretching effect.

[0033] See also Figure 2 , 3The pinch roller group 10 includes a first pinch roller 14 and a second pinch roller 15. The first bearing seats 13 are installed at both ends of the first pinch roller 14 and the second pinch roller 15 respectively. The first pinch roller 14 and the second pinch roller 15 abut against each other. A first motor 17 is installed on the first bearing seat 13 at one end of the first pinch roller 14 through a first support seat 18. The output shaft of the first motor 17 is connected to the first pinch roller 14 in transmission. The first pinch roller 14 and the second pinch roller 15 are installed with gears 12 at one end away from the first motor 17. The two gears 12 are meshed for transmission. The stretching roller group 20 includes a stretching roller 23. The second bearing seats 22 are installed at both ends of the stretching roller 23 respectively. The second bearing seats 22 are located above the two first bearing seats 13. The first pinch roller 14 is driven to rotate by the first motor 17, and the first pinch roller 14 drives the second pinch roller 15 to rotate through the gear 12. See Figure 4 , so that the first clamping roller 14 and the second clamping roller 15 run in opposite directions to clamp and pull the cloth 70. In the process of clamping and pulling, the cloth 70 can drive the spreading roller 23 to rotate, so that the wrinkled cloth 70 can be stretched out by the spreading roller 23.

[0034] The spreading roller 23 adopts the existing technology, such as a film spreading roller disclosed in CN210192956U. The working principle of the spreading roller 23 is to spread the cloth 70 to both ends through the spiral lines on the roller surface that are symmetrical and have opposite spiral directions.

[0035] In this embodiment, the first support seat 18 includes four rods and a mounting plate. One end of the four rods is connected and supported to the mounting plate, and the other end is connected and supported to the first bearing seat 13. The first motor 17 is mounted on the mounting plate.

[0036] Furthermore, the pinch roller group 10 also includes a first frame-shaped seat 11, which is provided with two first frame-shaped seats 11, and the first bearing seats 13 at both ends of the first pinch roller 14 and the second pinch roller 15 are respectively slidably installed in the first frame-shaped seats 11 on both sides, and the first frame-shaped seat 11 is screwed with a clamping bolt 16, and the clamping bolt 16 abuts against the first bearing seat 13 on one side; the spread roller group 20 also includes a second frame-shaped seat 21, which is provided with two second frame-shaped seats 21, and the second bearing seats 22 at both ends of the spread roller 23 are respectively installed on the second frame-shaped seats 21 on both sides, and the two second frame-shaped seats 21 are correspondingly installed on the top of the two first frame-shaped seats 11. Through the above structure, the installation of the first bearing seat 13 and the second bearing seat 22 and the adjustment of the pressure between the first pinch roller 14 and the second pinch roller 15 are realized.

[0037] When in use, the clamping bolt 16 is screwed to adjust the pressure of the clamping bolt 16 against the first bearing seat 13 on one side, thereby adjusting the pressure between the first clamping roller 14 and the second clamping roller 15 .

[0038] Specifically, the first bearing seat 13 is a UCT series slider bearing seat, and the upper and lower ends of the first bearing seat 13 are respectively provided with slide grooves, which cooperate with the frame seat. The second frame seat 21 can be a UCF bearing seat, or a UCF series bearing seat.

[0039] See also Figure 2 The tops of the two second frame-shaped seats 21 are connected to the connecting plate 26 to improve the stability of the second frame-shaped seats 21 on both sides. Specifically, the two ends of the connecting plate 26 are connected to the connecting plate 26 by welding or bolts.

[0040] See also Figure 3 A second motor 24 is installed on the second bearing seat 22 at one end of the stretching roller 23 through a second support seat 25, and the output shaft of the second motor 24 is transmission-connected with the stretching roller 23. The stretching roller 23 is driven to rotate by the second motor 24 to improve the stretching efficiency of the cloth. Preferably, the second support seat 25 has the same structure as the first support seat 18.

[0041] See also Figure 2 , the two ends of the first guide roller 60 are mounted on the first frame-shaped seat 11 on both sides, or the two ends of the first guide roller 60 are connected to the first frame-shaped seat 11 after the connecting plates are installed. The first frame-shaped seat 11 can be provided with a mounting hole, and the two ends of the first guide roller 60 are inserted into the mounting hole, or the screws are connected to the first guide roller 60 through the mounting hole. Of course, the two ends of the first guide roller 60 can also use bearing seats, such as UCP bearing seats, and the two ends of the first guide roller 60 are installed on the bearing seats. The bearing seats can be installed on the first frame-shaped seat 11, on the frame 40, or on the upstream equipment. The connecting plate structure of the third guide roller 30 can also be used for installation.

[0042] The first guide roller 60 can be a drum with a rotatable central axis, or a stretching roller. When a stretching roller is used, the wrinkles of the cloth can be pre-stretched, thereby improving the stretching efficiency.
