For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0022] The slitting machine with quick-release cutter for slitting nonwoven fabrics provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.

[0023] Embodiment 1: like Figures 1 to 9 As shown, the embodiment of the present application provides a slitting machine with a quick-release tool for non-woven fabric slitting, including a slitting machine body 1, a lifting box 2, a slitting knife groove 3, a slitting knife 4, a quick-release mechanism 5 and a positioning mechanism 6. The quick-release mechanism 5 includes a plurality of sockets 51, which are arranged at intervals on the slitting knife 4; a plurality of plugs 52, which are fixed at intervals on the inner side wall of the slitting knife groove 3 and plugged into each socket 51; a pair of extrusion blocks 53, which are slidably mounted at both ends of the slitting knife groove 3; a pair of sliding frames 54, which are slidably mounted in the inner cavity of the lifting box 2, and are controlled to move relative to each other by a gear drive mechanism 7, so as to move relative to adjacent extrusion blocks. The blocks 53 are connected by a connecting rod 55; a pair of vertical grooves 56 are symmetrically arranged on the front side wall of the lifting box 2, with the lower end open and the upper end bent inward to connect with the inner cavity of the lifting box 2; a pair of flip rods 57, the middle part of which is movably installed in the vertical groove 56 through a hinge, and the top end extends into the inner cavity of the lifting box 2, and is connected to the corresponding sliding frame 54 through a transmission mechanism 8; a pressure plate 58, which is fixed at the lower end of the pair of flip rods 57 and can enter the slitting groove 3, when the pair of sliding frames 54 move away from / approach each other, the pair of extrusion blocks 53 approach / move away from each other, and the lower ends of the pair of flip rods 57 approach / move away from the slitting groove 3.

[0024] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when installing the slitting tool 4, the top of the slitting tool 4 is placed between the slitting tool groove 3 and the pressure plate 58, and then pressed into the slitting tool groove 3, and each plug 52 is inserted into each socket 51 on the slitting tool 4 until the inner side wall of the top of the slitting tool 4 is tightly pressed against the inner side wall of the slitting tool groove 3, and then a pair of sliding frames 54 are controlled to move away from each other through the gear drive mechanism 7, and a pair of extrusion blocks 53 are pulled closer to each other through corresponding pull rods until the adjacent ends of a pair of extrusion blocks 53 are tightly pressed against the two ends of the top of the slitting tool 4. In this process, each transmission mechanism 8 moves with the movement of the corresponding sliding frame 54, controls a pair of flip rods 57 to flip around the hinge, and the lower end of each flip rod 57 moves toward the slitting tool groove 3 until the inner side wall of the pressure plate 58 is tightly pressed against the top side wall of the slitting tool 4, completing the installation of the slitting tool 4.

[0025] When removing the slitting tool 4, a pair of sliding frames 54 are controlled to approach each other through the gear driving mechanism 7, and a pair of extrusion blocks 53 are pushed away from each other through the corresponding pull rods, so that the pair of extrusion blocks 53 are separated from the contact with the two ends of the slitting tool 4. In this process, each transmission mechanism 8 moves in the opposite direction with the movement of the corresponding sliding frame 54, and controls a pair of flip rods 57 to flip around the hinge. The lower end of each flip rod 57 moves away from the slitting tool groove 3, and the pressure plate 58 also moves away from the slitting tool 4. Then, the slitting tool 4 is pushed out of the slitting tool groove 3 until each plug post 52 is separated from each plug hole 51, and the slitting tool 4 can be removed.

[0026] Embodiment 2: like Figures 1 to 4 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the sliding frame 54 includes a rack 541, which is meshed with the gear drive mechanism 7 for transmission; a transmission frame 542, which is fixed at one end of the rack 541, is U-shaped and has an opening horizontally facing outward, one end of the connecting rod 55 is fixedly connected to the end of the rack 541 away from the transmission frame 542, and the other end passes through the through groove 543 to the outside of the lifting box 2 and is fixedly connected to the top surface of the corresponding extrusion block 53.

[0027] Furthermore, the transmission mechanism 8 includes a pair of inclined grooves 81, which are symmetrically arranged on the opposite inner walls of the transmission frame 542; a spherical connector 82, which is rotatably installed on the inner end of the flip rod 57; a connecting rod 83, which is slidably inserted into the spherical connector 82, and whose two ends are slidably installed in the pair of inclined grooves 81, and the distance between the end of the pair of inclined grooves 81 close to the gear drive mechanism 7 and the vertical groove 56 is greater than the distance between the other end and the vertical groove 56.

[0028] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the gear driving mechanism 7 rotates forward / reversely, it drives a pair of racks 541 to move, so that a pair of transmission frames 542 move away from / approach each other, and each connecting rod 55 is respectively installed at one end of each rack 541 away from the transmission frame 542. When each transmission frame 542 moves away from / approaches each other, the left transmission frame 542 moves to the left / right, and the right extrusion block 53 is pulled to move to the left / right by the connecting rod 55. When the right transmission frame 542 moves to the right / left, the left extrusion block 53 is pulled to move to the right / left by the corresponding connecting rod 55, so that the pair of extrusion blocks 53 approach / move away from each other when the transmission frames 542 move away from / approach each other; And when a pair of transmission frames 542 move away from / approach each other, the left pair of inclined grooves 81 and the right pair of inclined grooves 81 move away from / approach each other, and each connecting rod 83 slides toward the other end in the corresponding inclined groove 81, approaching / moving away from the vertical groove 56, and each spherical connecting member 82 also slides on the outside of the corresponding connecting rod 83, and approaches / moves away from the vertical groove 56 together with the corresponding connecting rod 83, so that the middle part of each flip rod 57 flips around the hinge, and the lower end drives the pressure plate 58 to enter / disengage the slitting knife groove 3, pressing / disengaging the slitting tool 4.

[0029] Embodiment 3: like Figures 5 and 6 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the gear drive mechanism 7 includes a gear 71, which is rotatably installed in the inner cavity of the lifting box 2 through an inner shaft 72 and meshes with each rack 541; an outer shaft 73, which is rotatably embedded in the front side wall of the lifting box 2 through a bearing and is coaxial with the inner shaft 72; and a friction plate 74, which is fixed at the inner end of the outer shaft 73 and is frictionally transmitted with the surface of the gear 71.

[0030] Furthermore, the gear drive mechanism 7 also includes an annular groove 75, which is arranged on the rear side wall of the inner cavity of the lifting box 2 and is arranged around the inner rotating shaft 72; a return spring 76, which is sleeved on the inner rotating shaft 72, and its two ends are respectively abutted against the bottom end of the annular groove 75 and the adjacent end surface of the gear 71; a shift ring 77, which is fixed at the free end of the inner rotating shaft 72 and abuts against the other end surface of the gear 71; a plurality of limiting grooves 78 are arranged on the inner circumferential wall of the annular groove 75 at intervals along the circumferential direction; a separating member 9, which is used to separate the friction disk 74 that continues to rotate from the gear 71 that cannot continue to rotate, and the inner ring of the gear 71 is slidably sleeved on the inner rotating shaft 72.

[0031] Preferably, the number of the limiting grooves 78 is an even multiple of the number of teeth on the peripheral wall of the gear 71 .

[0032] Furthermore, the separator 9 includes a pair of separation rods 91, which are symmetrically fixed on the peripheral wall of the friction plate 74; a pair of arc-shaped separation blocks 92, which are fixed at intervals on the edge of the surface of the gear 71 facing the friction plate 74, with a bevel 93 at one end and a blocking block 94 on the top surface of the other end.

[0033] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the outer end of the outer shaft 73 can be provided with an inner hexagonal groove or a fixed hand wheel. When the inner hexagonal groove is provided, the inner hexagonal wrench is inserted into the inner hexagonal groove, and the outer shaft 73 is rotated clockwise / counterclockwise. The surface of the friction plate 74 and the surface of the gear 71 are both fixed with friction plates. When the friction plate 74 rotates clockwise / counterclockwise, the gear 71 acts synchronously to control the relative movement of the pair of racks 541, so that the pair of transmission frames 542 move away from / close to each other. When the outer shaft 73 rotates clockwise, when the ends of a pair of extrusion blocks 53 are in contact with the top of the left and right side walls of the slitting tool 4, and the pressure plate 58 is also in contact with the front side wall of the slitting tool 4, the pair of racks 541 cannot move further, and the gear 71 cannot rotate further. The outer shaft 73 continues to rotate, so that each separation rod 91 contacts the inclined surface 93 of each separation arc block and slides to the top surface of each separation arc block under the guidance of the corresponding inclined surface 93. In this process, the gear 71 is pushed to move in the direction of the annular groove 75, the return spring 76 is compressed and shortened, and half of the teeth on the outer peripheral wall of the gear 71 are engaged with part of the limiting groove 78, and the other half is still meshed with each rack 541, so that the pressure plate 58 and the pair of extrusion blocks can be moved. The position of block 53 is fixed to ensure that the slitting tool 4 is firmly installed. Then the outer shaft 73 continues to be rotated until each separation rod 91 contacts the blocking block 94 on the corresponding arc-shaped separation block 92. The staff will know that the installation and fixation of the slitting tool 4 has been completed. Then, if the outer shaft 73 is rotated counterclockwise, each separation rod 91 returns to the lower end of the corresponding inclined surface 93, and the reset spring 76 releases the elastic potential energy, pushing the gear 71 close to the friction plate 74, and the surface of the friction plate 74 can contact the surface of the gear 71. Continuing to rotate the outer shaft 73 counterclockwise can make the friction plate 74 and the gear 71 rotate counterclockwise, so that a pair of transmission frames 542 approach each other, and the pressure plate 58 and a pair of extrusion blocks 53 are out of contact with the slitting tool 4.

[0034] The number of limiting grooves 78 is several times (such as 2, 4, or 6 times) greater than the number of teeth on the peripheral wall of the gear 71, so that the gear 71 can slide into the annular groove 75 when rotating at a very small angle, and the teeth on the peripheral wall can engage with some of the limiting grooves 78.

[0035] Embodiment 4: like Figures 7 to 9 As shown, in the present embodiment, in addition to the structural features of the aforementioned embodiments, the positioning mechanism 6 includes a pair of side beams 61, each of which has a floating groove 62 at the lower end, which is fixed in the slitting machine body 1 and located on both sides of the lifting box 2; a pair of pressure beams 63, which are respectively installed in the floating grooves 62; a number of lifting control parts 10, which are respectively installed on the inner wall of each side beam 61, and are transmission-connected with the corresponding pressure beam 63, and cooperate with the pressure plate 58 or the outer wall of the lifting box 2.

[0036] Furthermore, the positioning mechanism 6 also includes a plurality of spring grooves 64, which are respectively arranged on the top of each side beam 61, and the bottom is connected to the corresponding floating groove 62 through a through hole 67; a plurality of floating rods 65, all of which are T-shaped, are slidably installed in each spring groove 64 through a floating spring 66, and the lower end passes through the corresponding through hole 67 and is fixedly connected to the top surface of the corresponding pressure beam 63.

[0037] Preferably, the lifting control members 10 are arranged between the spring slots 64 at intervals.

[0038] Furthermore, the lifting control component 10 includes a lifting control chamber 101, which is arranged at the top of the floating groove 62; a bidirectional screw 102, whose two ends are rotatably mounted on the side walls at both ends of the floating groove 62; a side groove 103, which is arranged on the inner wall of the side beam 61 and connected to the floating groove 62; a fan-shaped flip block 104, which is fixed in the middle of the bidirectional screw 102 and movably installed in the side groove 103, and an outward thrust spring 105 is provided between the inner wall and the inner end side wall of the floating groove 62; a pair of guide rods 106, which are symmetrically fixed on both sides of the floating groove 62 and perpendicular to the bidirectional screw 102; a pair of push swing arms 107, the top end of which is transmission-connected to the bidirectional screw 102 through a screw sleeve 108, and the middle part is transmission-connected to the guide rod 106 through a transmission groove 109, and each screw sleeve 108 is rotationally connected to the corresponding push swing arm 107.

[0039] In this embodiment of the present application, due to the adoption of the above-mentioned structure, after the installation of the slitting tool 4 is completed, the lifting box 2 is lowered until the pressure plate 58 is located between a pair of side beams 61, and contacts the outer side walls of each fan-shaped flip block 104. At this time, the outer side wall of the pressure plate 58 and the other side wall of the lifting box 2 are respectively in contact with the inner side walls of the side beams 61 on both sides. When cutting the non-woven fabric, the lifting box 2, the pressure plate 58 and the slitting tool 4 are lowered together, and the lifting box 2 and the pressure plate 58 push each fan-shaped flip block 104 and the corresponding bidirectional screw 102 to rotate, and each fan-shaped flip block 104 enters the corresponding side groove 103 and the lifting control chamber 101, and each screw sleeve 108 slides toward the outer end of the corresponding bidirectional screw 102, driving each push swing arm 107 to swing, and under the guidance of each guide rod 106 and the corresponding transmission groove 109, the lower end of each push swing arm 107 moves downward, pushing each pressure beam 63 downward, and each floating rod 65 descends, and each floating spring 66 is compressed and shortened until a pair of pressure beams 63 presses the nonwoven fabric to be cut on the working table of the cutting machine body 1, and then the lifting box 2 continues to descend, and the outer wall of each fan-shaped flip block 104 slides and rubs against the outer wall of the pressing plate 58 or the outer wall of the lifting box 2 until the slitting tool 4 is pressed by a pair of pressure beams 63 to complete the slitting of the nonwoven fabric at both ends, and the lifting box 2 rises to the top of each side groove 103, and each outward push spring 105 releases its elastic potential energy, pushing each fan-shaped flip block 104 and the corresponding bidirectional screw 102 to rotate in the opposite direction The outer side of each fan-shaped flip block 104 extends out of the side groove 103, and each screw sleeve 108 moves toward the corresponding fan-shaped flip block 104 on the corresponding bidirectional screw 102. The upper end of each push swing arm 107 also wants to approach the corresponding fan-shaped flip block 104. Under the guidance of each guide rod 106 and the corresponding transmission groove 109, the lower end of each push swing arm 107 is lifted, and each floating spring 66 releases its elastic potential energy, pushing each floating rod 65 to rise, driving a pair of floating beams to lift upward.
