DETAILED DESCRIPTION

[0020] In order to better understand the technical solution of the present application, the technical solution of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] Reference Figure 1 and Figure 2 , the automatic feeding device 200 of the medical non-woven fabric production line is arranged in the direction of the non-woven fabric outlet in the production line 100, and the automatic feeding device 200 includes a side frame 1, a large-diameter active roller 2, a winding roller 3, an empty roll roller 4, a pressing mechanism 5, a turning mechanism 1 6, a cutting mechanism 7, a turning mechanism 2 8 and a tensioning mechanism 9. The side frame 1 is provided with two groups, and the two groups of side frames 1 are symmetrically arranged on both sides of the non-woven fabric outlet direction. The diameter of the large-diameter active roller 2 is relatively large and much larger than the diameters of the winding roller 3 and the empty roll roller 4. The active roller shaft 21 in the large-diameter active roller 2 is a driving shaft. The two ends of the active roller shaft 21 are respectively installed on the side frames 1 on both sides through shaft seats. The side frame 1 is equipped with a motor to drive the large-diameter active roller 2 to rotate. The winding roller 3 is located on the side of the large diameter active roller 2 away from the non-woven fabric outlet. The winding roller 3 is used to wind the produced non-woven fabric. The two ends of the winding shaft rod 31 in the winding roller 3 extend to the side frames 1 on both sides respectively. After the winding roller 3 winds up enough non-woven fabric, the empty winding roller 4 is placed on the side of the large diameter active roller 2 close to the non-woven fabric outlet, and the two ends are placed on the side frames 1 on both sides. The axis height of the winding roller 3 is consistent with the axis height of the large diameter active roller 2, and the axis height of the empty winding roller 4 is higher than the axis height of the large diameter active roller 2. There are two sets of pressing mechanisms 5, and the two sets of pressing mechanisms 5 are respectively located at the two ends of the empty winding shaft rod 41 of the empty winding roller 4. There are two sets of flipping mechanisms 1 6, and the two sets of flipping mechanisms 1 6 are respectively located at the two ends of the active roller shaft rod 21. The cutting mechanism 7 is arranged on the outside of the large diameter active roller 2. The flipping mechanism 2 8 is arranged on the side frame 1, and is used to flip the cutting mechanism 7 along the surface of the large diameter active roller 2. The tensioning mechanism 9 is provided with two groups, which are respectively located at the two ends of the winding shaft rod 31 .

[0022] Reference Figure 3 and Figure 4 A cross rail 11 is fixed to the top surface of the side frame 1, and a winding rail groove 311 for matching with the cross rail 11 is provided at the end of the winding shaft rod 31, and an empty winding rail groove 411 for matching with the cross rail 11 is provided at the end of the empty winding shaft rod 41 of the empty winding roller 4. By utilizing the cross rail 11, the winding roller 3 and the empty winding roller 4 can roll stably on the cross rail 11.

[0023] Reference Figure 3 and Figure 4The pressing mechanism 5 includes a rotating sleeve 51, a swing plate 52, a pressing plate 53, and a digital hydraulic servo cylinder 54. The rotating sleeve 51 is sleeved on the end of the active roller shaft 21 of the large diameter active roller 2. The rotating sleeve 51 and the active roller shaft 21 are connected by a bearing, so that the rotating sleeve 51 can rotate freely on the active roller shaft 21. Therefore, the active roller shaft 21 and the rotating sleeve 51 can rotate asynchronously. The swing plate 52 is vertically fixed to the outer surface of the rotating sleeve 51. The swing plate 52 is located on the outer side of the side frame 1. A slide rail 521 is fixed on the swing plate 52. The slide rail 521 is perpendicular to the rotating sleeve 51. A slider 522 is slidably arranged on the slide rail 521. The pressing plate 53 is fixed on the slider 522. One side of the pressing plate 53 has an opening in a U shape. Both ends and the bottom edge of the opening of the pressing plate 53 are rotatably provided with pressing rollers 531. The axis of the pressing rollers 531 is parallel to the axis of the rotating sleeve 51. The three pressing rollers 531 are all fitted on the circumferential surface of the end of the empty reel rod 41. The digital hydraulic servo cylinder 1 54 is fixed on the swing plate 52. The telescopic cylinder of the digital hydraulic servo cylinder 1 54 is located on the inner side and fixedly connected to the slider 522. The digital hydraulic servo cylinder 1 54 is used to push the slider 522 to move in the direction of the rotating sleeve 51.

[0024] Continue to refer to Figure 4 The flip mechanism 16 includes a gear ring 61, a gear 62, and a drive motor 163. The gear ring 61 is coaxially connected to the outer peripheral surface of the rotating sleeve 51. The gear 62 is located below the gear ring 61, and the gear 62 is rotatably arranged on the side frame 1, and the gear 62 and the gear ring 61 are meshed with each other. The drive motor 163 is installed on the side frame 1, and the drive motor 163 is used to drive the gear 62 to rotate.

[0025] The driving motor 63 is started, driving the gear 62 to rotate, the gear 62 drives the gear ring 61 to rotate, and the gear ring 61 drives the rotating sleeve 51 to rotate, so that the swing plate 52 can rotate around the active roller shaft 21 of the large diameter active roller 2. Therefore, when the opening of the clamping plate 53 is inserted into the empty roll 4, the empty roll 4 can be pushed to approach the large diameter active roller 2 until they are in contact with each other under the continuous rotation of the swing plate 52. Due to the self-rotation of the large diameter active roller 2, the empty roll 4 can be driven to rotate under the action of friction, and the rotation direction is opposite to that of the large diameter active roller 2. Then, the flipping mechanism 6 continues to drive the swing plate 52 to rotate, so that the empty roll 4 can bypass the top of the large diameter active roller 2 and flip to the other side of the large diameter active roller 2, and the digital hydraulic servo cylinder 54 continues to give thrust to the clamping plate 53, so that the empty roll 4 is always in contact with the large diameter active roller 2 during the flipping process.

[0026] Reference Figure 3As shown, the cutting mechanism 7 includes a row frame 71, a cutting frame 72, and a cutting machine 73. The row frame 71 is located on the outer surface of the large-diameter active roller 2, and there is a gap between the row frame 71 and the outer surface of the large-diameter active roller 2. The length direction of the row frame 71 is consistent with the length direction of the large-diameter active roller 2. Light rods 711 are arranged on both sides of the top of the row frame 71. When the cutting machine 73 is in operation, the light rods 711 on both sides support the non-woven fabric. The cutting frame 72 is installed on the row frame 71 through a linear moving component. The linear moving component can be composed of a screw rod, an optical axis, a nut seat and a motor. The linear moving component is used to drive the cutting frame 72 to move along the length direction of the row frame 71. The cutting machine 73 is fixed on the cutting frame 72. The cutting wheel of the cutting machine 73 is located between the light rods 711 on both sides. The cutting machine 73 is used to cut the non-woven fabric on the light rods 711.

[0027] Continue to refer to Figure 3 As shown, the flip mechanism 8 includes a flip plate 81, a synchronous wheel 82 and a drive motor 83. Two flip plates 81 are provided, and are respectively located at the two ends of the frame 71. One end of the flip plate 81 is fixed to the end of the frame 71, and the other end is connected to the active roller shaft 21 of the large diameter active roller 2 through a bearing, so that the flip plate 81 can rotate freely on the active roller shaft 21. Therefore, the active roller shaft 21 and the flip plate 81 can rotate asynchronously. The synchronous wheel 82 is sleeved on the active roller shaft 21 of the large diameter active roller 2, and the synchronous wheel 82 is fixed to the side wall of the flip plate 81. The drive motor 83 is fixed on the side frame 1 and is located below the active roller shaft 21. The output shaft of the drive motor 83 and the synchronous wheel 82 are belt-driven.

[0028] When the cutting mechanism 7 is not needed, the frame 71 is located below the large-diameter active roller 2. When the non-woven fabric between the large-diameter active roller 2 and the winding roller 3 needs to be cut, the drive motor 83 is started. Under the belt drive, the flip plate 81 can be rotated around the active roller shaft 21 of the large-diameter active roller 2 so that the frame 71 can be flipped to the top of the large-diameter active roller 2. Then the linear moving component on the frame 71 is started, and the cutting machine 73 is driven by the linear moving component to move, so that the cutting machine 73 can be moved from one end of the frame 71 to the other end. During the movement, the non-woven fabric between the large-diameter active roller 2 and the winding roller 3 can be cut. After cutting, the frame 71 is flipped to the bottom of the large-diameter active roller 2.

[0029] Reference Figure 5As shown, the tensioning mechanism 9 includes an articulated plate 91 and a digital hydraulic servo cylinder 92. One end of the articulated plate 91 is hinged to the side frame 1, and the other end is in a U shape, and both ends of the U shape are rotatably provided with tensioning rollers 911, the axis of the tensioning roller 911 is parallel to the axis of the winding shaft rod 31, and the two tensioning rollers 911 are respectively located on both sides of the winding shaft rod 31 of the winding roller 3, and the tensioning rollers 911 are in contact with the surface of the winding shaft rod 31. The cylinder seat of the digital hydraulic servo cylinder 92 is hinged to the side frame 1, and the end of the internal telescopic rod of the digital hydraulic servo cylinder 92 is hinged to the articulated plate 91, and the digital hydraulic servo cylinder 92 is used to pull the articulated plate 91 closer to one side of the large-diameter active roller 2.

[0030] Under the action of the digital hydraulic servo cylinder 2 92, pressure can be continuously applied to the reel 31, and the direction of the pressure application is toward the large-diameter active roller 2, so that the non-woven fabric wound on the surface of the reel 3 can always fit with the large-diameter active roller 2, and then the reel 3 can rotate in the opposite direction to the large-diameter active roller 2, so that the reel 3 can continue to reel the non-woven fabric. When the cutting mechanism 7 cuts the non-woven fabric, the digital hydraulic servo cylinder 2 92 is used to push the reel 31 in the opposite direction, so that the reel 3 can be pushed away from the large-diameter active roller 2.

[0031] This application can explain its functional principle through the following operation methods:

[0032] The non-woven fabric drawn out from the non-woven fabric outlet in the production line 100 passes around the upper surface of the large-diameter active roller 2 and is wound onto the winding roller 3. Under the action of the tensioning mechanism 9, the non-woven fabric wound on the surface of the winding roller 3 can always be in contact with the large-diameter active roller 2, and the winding roller 3 can continuously wind up the non-woven fabric.

[0033] When the winding roller 3 is about to finish winding, the empty winding roller 4 is placed on the side of the large diameter active roller 2 close to the non-woven fabric outlet, and the turning mechanism 1 6 is started, so that the swing plate 52 can rotate around the active roller shaft 21 of the large diameter active roller 2. Therefore, after the opening of the pressing plate 53 is inserted into the empty winding roller 4, the swing plate 52 can continuously rotate to push the empty winding roller 4 toward the large diameter active roller 2 until they are in contact with each other. Then the turning mechanism 2 8 is started, and the cutting mechanism 7 is turned over to the top of the large diameter active roller 2. The cutting mechanism 7 is started to cut the non-woven fabric. The non-woven fabric on the side of the large diameter active roller 2 close to the non-woven fabric outlet in the production line 100 will be wound around the empty winding roller 4. The continuous rotation of the empty winding roller 4 can continuously wind up the non-woven fabric. At this time, the digital hydraulic servo cylinder 2 92 is used to push the winding shaft 31 in the opposite direction to push the winding roller 3 away from the large diameter active roller 2.

[0034] Then, the flipping mechanism 6 continues to drive the swing plate 52 to rotate, so that the empty roll 4 can bypass the top of the large-diameter active roll 2, and the empty roll 4 will flip to the other side of the large-diameter active roll 2. At this time, the empty roll 4 is transformed into the winding roll 3, and the non-woven fabric is continuously wound.

[0035] Therefore, after the winding roller 3 completes the winding work, the empty winding roller 4 is automatically replaced, and the rolled non-woven fabric is automatically replaced without stopping the machine, thereby improving production efficiency.

Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
