The device 2 is used to roll up the gauze, and during the process of rolling up the gauze, the material receiving device 2 can drive the feeding shaft 14 of the feeding device 1 to rotate synchronously to unwind the gauze roll. In addition, the gauze can be guided by arranging a cloth guiding device 5, and the gauze can be cut at the same time by arranging several groups of pneumatic cutting devices 3 during the transmission process. In this way, when the cut gauze is wound on the material receiving device 2, several small gauze rolls can be formed. In general, the entire slitting process of the utility model is relatively simple, so that the gauze roll can be easily cut.

[0038] The specific arrangement of the feeding device 1 is as follows: the feeding device 1 includes a support frame 11 arranged in parallel with the material receiving device 2, and two support seats 12 are installed at both ends of the support frame 11 and are vertically opposite to each other. Specifically, the vertical cross-sections of the support seats 12 are all trapezoidal structures with narrow tops and wide bottoms, and one of the inclined surfaces of the support seats 12 faces the material receiving device 2; each support seat 12 is slidably connected to a U-shaped roller block 13 that can move along the outer periphery of the support seat 12, and a U-shaped roller block 13 that can drive the two U-shaped roller blocks 13 to move synchronously is installed between the two support seats 12. A feeding mechanism 16 that moves step by step, two U-shaped roller blocks 13 are arranged relatively to each other, and a feeding shaft 14 arranged parallel to the support frame 11 is detachably connected between the two U-shaped roller blocks 13, and the feeding shaft 14 can be arranged as an air-expanding shaft, so that after the gauze roll is sleeved on the feeding shaft 14, the gauze roll can be easily fixed; both ends of the feeding shaft 14 are sleeved and rotatably connected with a first roller 15 located in the U-shaped roller block 13; a locking device 4 for locking the first roller 15 is installed on one side of the top of each support seat 12 close to the material receiving device 2.

[0039] Specifically, during feeding, the feeding mechanism 16 can first drive the U-shaped roller block 13 to move to the bottom position of the support seat 12, and make the U-shaped roller block 13 located on the side of the support seat 12 away from the material receiving device 2. At this time, the U-shaped opening of the U-shaped roller block 13 is tilted upward, and then after the gauze roll is put on the feeding shaft 14, the first rollers 15 at both ends of the feeding shaft 14 can be manually clamped in the U-shaped roller block 13 respectively. At this time, the gauze roll can be transported from a low place to a high place through the feeding mechanism 16 until the U-shaped roller block 13 is moved to the top surface position of the support seat 12, and then when the U-shaped roller block 13 moves into place, that is, when the U-shaped roller block When the U-shaped opening of 13 is facing the receiving device 2, since the first rollers 15 are installed at both ends of the feeding shaft 14, it is convenient to push the feeding shaft 14 to move the first rollers 15 to the position of the locking device 4 to complete the feeding, and this feeding method does not require multiple people to hold the gauze roll for a long time, so that it is convenient to load the gauze roll and can reduce the labor intensity of the workers; then when the locking device 4 locks the position of the first roller 15, the feeding shaft 14 can be rotated, so that when the receiving device 2 is in the process of winding the gauze, it can drive the feeding shaft 14 to rotate synchronously to unwind the gauze roll, that is, the feeding shaft 14 is a driven shaft.

[0040] The specific configuration of the feeding mechanism 16 is as follows: Figure 1 , Figure 3 , Figures 5 to 7 and Fig.10 As shown, each support seat 12 includes two support plates 121 that are vertically opposite and spaced apart, and each support plate 121 is mounted on the support frame 11. The feeding mechanism 16 includes two groups of chain transmission components that are oppositely arranged. The chain transmission component is a chain transmission mechanism in the prior art, which includes a driving sprocket, a plurality of driven sprockets and annular chains, etc.; each group of chain transmission components is respectively located between the two support plates 121 of the support seat 12, and each group of chain transmission components is distributed along the circumference of the support seat 12. The two groups of chain transmission components are also connected by a transmission shaft 161, and one end of the transmission shaft 161 is connected to a feeding motor 162, and the feeding motor 162 is forward and reverse. Rotating motor; two U-shaped roller blocks 13 are respectively installed on the chain drive assembly. Specifically, the connection method of the U-shaped roller block 13 and the chain drive assembly is the existing technology, that is, the U-shaped roller block 13 is connected to one of the links of the circular chain, and each U-shaped roller block 13 is respectively located between the two support plates 121 of the support seat 12 and is slidably connected to the support seat 12. Specifically, when in use, after starting the feeding motor 162, the transmission shaft 161 can be used to drive the two groups of chain drive assemblies to run synchronously, so that the two U-shaped roller blocks 13 can be driven to move synchronously along the outer periphery of the support seat 12, thereby driving the feeding shaft 14 to move back and forth between high and low places.

[0041] The specific configuration of the locking device 4 is as follows: Figure 1 , Figures 3 to 7 , Fig. 9 and Fig.10 As shown, the locking devices 4 include a U-shaped locking block 41 installed on the support seat 12, the U-shaped openings of the U-shaped locking blocks 41 are away from the receiving device 2, and the tops of the U-shaped locking blocks 41 are threadedly connected with locking screws 42 that vertically penetrate the U-shaped locking blocks 41, and the tops of each locking screw 42 are fixedly connected with a handwheel 43. When in use, the handwheel 43 can facilitate the rotation of the locking screw 42; specifically, when the first roller 15 moves into the U-shaped locking block 41, by rotating the locking screw 42, after the bottom end of the locking screw 42 is pressed against the first roller 15, the position of the first roller 15 can be locked, and at this time, the feeding shaft 14 can be rotated.

[0042] Since the feeding shaft 14 is a driven shaft when the gauze roll is unwound, when the receiving device 2 stops rewinding, the feeding shaft 14 will continue to rotate under the action of inertia, which will cause the gauze to loosen. Figure 1 , Figure 3 , Figure 4 and Figures 6 to 10 As shown, a magnetic powder brake 10 arranged parallel to the feeding shaft 14 is installed on the outer side of one of the support seats 12, a first gear 101 is sleeved on the output shaft of the magnetic powder brake 10, a second gear 141 capable of meshing with the first gear 101 is sleeved on one end of the feeding shaft 14, and a first roller 15 arranged on the feeding shaft 14 close to the second gear 141 is an I-shaped roller, and the inner bottom surface of the U-shaped locking block 41 opposite to the I-shaped roller includes a connected plane 411 and a concave surface 412, the concave surface 412 is located on the inner side of the plane 411 and is lower than the plane 411. Specifically, when in use, the I-shaped roller will move from the plane 411 during the process of moving into the U-shaped locking block 41. 1 falls into the concave surface 412, so that the second gear 141 can have a falling action to mesh with the first gear 101; and by providing the magnetic powder brake 10, when the material receiving device 2 stops winding, the magnetic powder brake 10 can be energized. At this time, under the action of the second gear 141 and the first gear 101, the feeding shaft 14 can be prevented from continuing to rotate, thereby avoiding the gauze from being loosened; and when the feeding shaft 14 is unwinding the gauze roll, the magnetic powder brake 10 is in a power-off state, at this time, the second gear 141 can drive the first gear 101 to rotate; in addition, by providing the I-shaped roller, when the first roller 15 is moved into the U-shaped locking block 41, the feeding shaft 14 can be prevented from axial movement.

[0043] Since the gauze may deviate from the direction when it is conveyed, Figure 1 , Figure 3 , Figures 5 to 7, Fig.10 and Fig.11 As shown, the feeding device 1 also includes a control box 17 and a frame 18 arranged parallel to the support frame 11, and the control box 17 is a PLC control system in the prior art; the four corners of the frame 18 are equipped with height-adjustable supports 181, specifically, each support 181 is equipped with a vertically distributed threaded rod 183, the threaded rod 183 is threadedly connected to the frame 18 and penetrates the frame 18, so that when in use, the height position of the support 181 can be adjusted by rotating the threaded rod 183, so that the position of the frame 18 can be leveled; the support frame 11 is installed on the frame 18 and is slidably connected to the frame 18 along the length direction of the frame 18. Specifically, the specific way in which the support frame 11 is slidably connected to the frame 18 is as follows: the frame 1 The four corners of 8 are fixedly connected with circular shafts 182 arranged parallel to the support frame 11, and the four bottom corners of the support frame 11 are installed with guide wheel assemblies 19, each set of guide wheel assemblies 19 includes two fixed plates 191 vertically oppositely distributed and installed on the bottom surface of the support frame 11, and two relatively arranged guide wheels 192 are rotatably connected between the two fixed plates 191, and the two guide wheels 192 of each set of guide wheel assemblies 19 are respectively connected with the circular shafts 182 in a rolling manner; the frame 18 is also installed with a correction device 9 that can drive the support frame 11 to move, so that when in use, when the gauze deviates, driven by the correction device 9, the support frame 11 can move along the length direction of the frame 18 to correct the gauze.

[0044] The specific setting method of the correction device 9 is as follows: the correction device 9 includes an electric telescopic rod 91 arranged parallel to the length direction of the frame 18, the telescopic end of the electric telescopic rod 91 is connected to the support frame 11, and the other end of the electric telescopic rod 91 is connected to the frame 18. Specifically, the electric telescopic rod 91 can be set as a servo electric cylinder that can stop at any position in the prior art. When in use, when the telescopic end of the electric telescopic rod 91 is in the process of extension and retraction, under the action of the guide wheel assembly 19 and the circular shaft 182, the support frame 11 can be driven to move along the length direction of the frame 18 to correct the gauze.

[0045] In addition, the control box 17 is electrically connected to the pneumatic cutting device 3, the feeding mechanism 16, and the electric telescopic rod 91, respectively, and the control box 17 is also electrically connected to a U-shaped correction sensor 92 and two travel switches 163 for preventing the U-shaped roller block 13 from overtravel. Specifically, the U-shaped correction sensor 92 is a sensor in the prior art that can be used to detect which side the gauze is deviating to, such as an ultrasonic sensor; when in use, the U-shaped correction sensor 92 can be installed on one side of the gauze transmission direction through the fixing rod 93, and the edge of the gauze can pass through the U-shaped correction sensor 92, so that when the gauze deviates, the U-shaped correction sensor 92 can transmit the deviation signal to the control box 17, and then the control box 17 can control the electric telescopic rod 91 to drive the support frame 11 to move along the length direction of the frame 18, so that the gauze can be automatically corrected; in addition, if Fig.13 As shown, the position of the U-shaped deflection correction sensor 92 on the fixed rod 93 is adjustable, that is, the U-shaped deflection correction sensor 92 is installed on the sleeve, the sleeve is slidably sleeved on the fixed rod 93, and the sleeve is threadedly connected with a bolt that penetrates the sleeve, so that when the screw end of the bolt is pressed against the fixed rod 93, the position of the U-shaped deflection correction sensor 92 can be fixed, so that it can be suitable for gauze rolls of different lengths; secondly, as Figure 5 As shown, two travel switches 163 are respectively installed at the top and bottom positions of the support seat 12, and a limit rod 131 that can touch the two travel switches 163 is installed on the U-shaped roller block 13. In this way, when in use, the travel of the U-shaped roller block 13 when moving on the support seat 12 can be limited to prevent the U-shaped roller block 13 from overtravel.

[0046] The specific configuration of the material receiving device 2 is as follows: Figures 1 to 3 , Figure 5 , Fig.12 , Figures 14 to 16As shown, the material receiving device 2 includes two vertically oppositely distributed support platforms 21, and two rotating shafts 22 arranged parallel to the support frame 11 and rotatable in the same direction are rotatably connected between the tops of the two support platforms 21, one of the rotating shafts 22 is drivingly connected to a material receiving motor 23, and a material receiving shaft 24 parallel to the rotating shaft 22 is also arranged between the two rotating shafts 22, and the material receiving shaft 24 can be set as an air expansion shaft; both ends of the material receiving shaft 24 are sleeved and rotatably connected with second rollers 25, and the second rollers 25 are respectively located in the first U-shaped card grooves opened on the support platforms 21; a vertically distributed gate-shaped frame 8 is also set between the two support platforms 21, and both sides of the gate-shaped frame 8 are equipped with A clamping device 7 is provided which can be extended and retracted in the vertical direction and is used to clamp the second roller 25. Specifically, during use, when the clamping device 7 is in an extended state, the second roller 25 can be clamped. At this time, after starting the material receiving motor 23, the two rotating shafts 22 can be driven to rotate in the same direction, and the two rotating shafts 22 can drive the material receiving shaft 24 to rotate during the same-direction rotation to reel in the gauze; and when the clamping device 7 is in a retracted state, the material receiving shaft 24 can be easily disassembled and assembled; in addition, a rotatable operating panel 26 is installed on one of the support platforms 21, and the operating panel 26 is electrically connected to the clamping device 7 and the material receiving motor 23, respectively.
