Description

Technical Field

[0001] This utility model belongs to the field of nonwoven fabric processing technology, and specifically relates to a nonwoven fabric cutting machine. Background Technology

[0002] Nonwoven fabric is a type of fabric formed without spinning or weaving. It is a new type of material that directly uses fibers to reinforce the fabric through physical or chemical methods. Nonwoven fabric has the characteristics of being moisture-proof, breathable, flexible, lightweight, flame-retardant, non-toxic, odorless, inexpensive, and recyclable. It can be used in various industries, such as sound insulation, heat insulation, heating elements, masks, clothing, medical applications, and filling materials. In the production of nonwoven fabric, it is necessary to wind the nonwoven fabric into rolls to facilitate secondary processing and use by different industries. After the nonwoven fabric is wound, it needs to be cut to prepare for the next winding operation. Existing cutting devices require pausing the previous winding before cutting and then winding the next roll. This requires stopping the machine midway for cutting, which cannot achieve continuous operation and affects the efficiency of winding.

[0003] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a nonwoven fabric cutting machine.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a nonwoven fabric cutting machine that can solve the problem that existing nonwoven fabric cutting devices require stopping the machine to cut and cannot operate continuously.

[0006] To achieve the above objectives, a specific embodiment of the present invention provides a nonwoven fabric cutting machine, comprising: a support frame and a cutting device; A rotating component is rotatably mounted on the support frame, and a pair of take-up rollers are rotatably mounted on the rotating component. A support is fixed on the support frame. The cutting device is mounted on a support and includes a fixed frame. A lifting assembly is installed below the fixed frame. A first fixed shaft and a second fixed shaft are fixed on the fixed frame. A movable shaft is rotatably mounted on the fixed frame. Guide rollers are rotatably mounted on the first fixed shaft, the second fixed shaft, and the movable shaft. A fixed seat is fixed on the fixed frame. A slide rail is fixed on the fixed seat. A slider is slidably mounted on the slide rail. A pair of rotating supports are fixed on the slider. A knife holder is rotatably mounted between the pair of rotating supports. A cutting blade is mounted on the knife holder. A first belt gear and a second belt gear are mounted on one side of the fixed seat. A belt is mounted on the first belt gear and the second belt gear. The belt is connected to the slider.

[0007] In one or more embodiments of this utility model, the lifting assembly is a lifting rod, the end of the lifting rod away from the fixed frame is connected to a support, and a lifting cylinder is installed in the support and connected to the lifting rod, so that the fixed frame can be moved up and down by the lifting rod.

[0008] In one or more embodiments of this utility model, limit blocks and fixing plates are fixed on both sides of the fixed frame at the moving shaft. The limit blocks are used to limit the moving shaft to prevent the moving shaft from rotating too much, which would cause the moving shaft to get stuck at the bottom of the winding roller when the fixed frame drives the moving shaft to rise, thus preventing the equipment from performing cutting operations.

[0009] In one or more embodiments of this utility model, a tension spring is installed between the movable shaft and a pair of fixed plates. The tension force of the tension spring is used to pull the movable shaft closer to the take-up roller, so that the movable shaft drives the guide roller to fit against the surface of the take-up roller.

[0010] In one or more embodiments of this utility model, a drive shaft is inserted into the fixing frame, one end of the drive shaft is fixedly connected to the first belt gear, the drive shaft is used to connect an external drive device to drive it to rotate, the drive shaft drives the first belt gear to rotate, and the first belt gear drives the belt to rotate together through the second belt gear.

[0011] In one or more embodiments of this utility model, a drive groove is fixed on the belt.

[0012] In one or more embodiments of this utility model, a driving block is fixed on the side of the slider near the belt. The driving block is inserted into the driving groove. By inserting the driving block into the driving groove, the belt drives the slider to slide on the slide rail.

[0013] In one or more embodiments of this utility model, a groove is cut into the slide rail, and a rack is fixed to one end of the slide rail near the first belt gear. When the slider slides on the slide rail, the gear moves in the slide groove. When the gear moves to the rack, it meshes with the rack, and the rack causes the gear to rotate. The gear drives the tool holder and the cutting blade to rotate.

[0014] In one or more embodiments of this utility model, a gear is fixed on the tool holder, a groove is cut into the slider, the gear passes through the groove and meshes with the rack, and after the gear meshes with the rack, the rack drives the gear to rotate.

[0015] In one or more embodiments of this utility model, a pair of torsion springs are installed between the blade holder and a pair of rotating supports. When the gear is no longer meshed with the rack, the torque of the pair of torsion springs is used to drive the blade holder to rotate, so that the blade holder is kept perpendicular to the slider, thereby cutting the non-woven fabric with the cutting blade.

[0016] Compared with the prior art, this utility model, through its related structural design, can wind another roll of nonwoven fabric while cutting the nonwoven fabric, achieving continuous winding without stopping the machine, thereby effectively improving production efficiency.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0021] like Figure 1-6 As shown, a nonwoven fabric cutting machine according to one embodiment of the present invention includes: a support frame 1 and a cutting device 2.

[0022] like Figure 1-2 As shown, a rotating component 101 is rotatably mounted on the support frame 1, and a pair of take-up rollers 102 are rotatably mounted on the rotating component 101. A support 103 is fixed on the support frame 1. The support frame 1 provides support. The rotating component 101 is used to drive the pair of take-up rollers 102 to rotate. A pair of drive devices need to be externally mounted on the side of the support 103 away from the take-up rollers 102, which are used to drive the pair of take-up rollers 102 to rotate respectively. A lifting cylinder is installed inside the support 103. The lifting cylinder is connected to the lifting rod 202 to drive the fixed frame 201 to lift.

[0023] like Figure 1-2As shown, the cutting device 2 is mounted on the support 103. The cutting device 2 includes a fixed frame 201, and a lifting assembly is installed below the fixed frame 201. A first fixed shaft 203 and a second fixed shaft 204 are fixed on the fixed frame 201. A movable shaft 205 is rotatably mounted on the fixed frame 201. Guide rollers 206 are rotatably mounted on the first fixed shaft 203, the second fixed shaft 204, and the movable shaft 205. The guide rollers 206 are used to guide the nonwoven fabric. The second fixed shaft 204 and the movable shaft 205 are used together to drive the guide rollers 206 to adhere to the surface of the take-up roller 102. After the cutting blade 225 cuts the nonwoven fabric, the nonwoven fabric is wound around the take-up roller 102 for a new winding. When the first fixed shaft 203 and the movable shaft 205 lift the nonwoven fabric upwards, they also tighten the nonwoven fabric to facilitate cutting.

[0024] like Figure 2-6 As shown, a fixed base 210 is fixed on the fixed frame 201, a slide rail 211 is fixed on the fixed base 210, a slider 212 is slidably arranged on the slide rail 211, a pair of rotating supports 213 are fixed on the slider 212, and a knife holder 221 is rotatably arranged between the pair of rotating supports 213. A cutting knife 225 is installed on the knife holder 221. The slider 212 drives the slide rail 211 and the cutting knife 225 to move along the trajectory of the slide rail 211, so that the cutting knife 225 cuts the non-woven fabric. By rotating the knife holder 221, when not cutting, the slide rail 211 drives the cutting knife 225 to rotate to the surface of the slider 212 to prevent the cutting knife 225 from accidentally hitting the non-woven fabric and causing damage.

[0025] like Figure 2-6 As shown, a first belt gear 214 and a second belt gear 215 are installed on one side of the fixed base 210. A belt 216 is installed on the first belt gear 214 and the second belt gear 215. The belt 216 is connected to the slider 212. The first belt gear 214 and the second belt gear 215 together drive the belt 216 to rotate, so that the belt 216 drives the slider 212 to move along the track of the slide rail 211, thereby cutting the non-woven fabric with the cutting blade 225.

[0026] like Figure 2-6 As shown, the lifting assembly is a lifting rod 202. The end of the lifting rod 202 away from the fixed frame 201 is connected to the support 103. The support 103 is used to install a lifting cylinder connected to the lifting rod 202, which drives the fixed frame 201 to move up and down. Limit blocks 207 and fixing plates 208 are fixed on both sides of the fixed frame 201 at the moving shaft 205. The limit blocks 207 are used to limit the moving shaft 205 to prevent the moving shaft 205 from rotating too much, which would cause the moving shaft 205 to get stuck at the bottom of the take-up roller 102 when the fixed frame 201 drives the moving shaft 205 to rise, thus preventing the equipment from performing the cutting operation.

[0027] like Figure 3-6 As shown, tension springs 209 are installed between the movable shaft 205 and a pair of fixed plates 208. The tension force of the tension springs 209 is used to pull the movable shaft 205 closer to the take-up roller 102, so that the movable shaft 205 drives the guide roller 206 to fit against the surface of the take-up roller 102. A drive shaft 217 is inserted into the fixed frame 201. One end of the drive shaft 217 is fixedly connected to the first belt gear 214. The drive shaft 217 is used to connect an external drive device to drive it to rotate. The drive shaft 217 drives the first belt gear 214 to rotate. The first belt gear 214 drives the belt 216 to rotate together through the second belt gear 215.

[0028] like Figure 3-6 As shown, a drive groove 218 is fixed on the belt 216, and a drive block 219 is fixed on the side of the slider 212 near the belt 216. The drive block 219 is inserted into the drive groove 218. By inserting the drive block 219 into the drive groove 218, the belt 216 drives the slider 212 to slide on the slide rail 211.

[0029] like Figure 3-6 As shown, a groove 223 is carved into the slide rail 211. A rack 224 is fixed to one end of the groove 223 near the first belt gear 214. When the slider 212 slides on the slide rail 211, the gear 222 moves in the groove 223. When the gear 222 moves to the rack 224, it meshes with the rack 224, causing the gear 222 to rotate. The gear 222 drives the tool holder 221 and the cutting blade 225 to rotate. The gear 222 is fixed on the tool holder 221. A groove 220 is carved into the slider 212. The gear 222 passes through the groove 220 and meshes with the rack 224. After the gear 222 meshes with the rack 224, the rack 224 drives the gear 222 to rotate.

[0030] like Figure 3-6 As shown, a pair of torsion springs 226 are installed between the blade holder 221 and a pair of rotating supports 213. When the gear 222 is no longer engaged with the rack 224, the torque of the pair of torsion springs 226 is used to drive the blade holder 221 to rotate, so that the blade holder 221 remains perpendicular to the slider 212, thereby enabling the cutting blade 225 to cut the non-woven fabric.

[0031] Working principle: When using this equipment, first place the winding roller as shown in the image. Figure 1 As shown, on the take-up roller 102 near the support 103, a drive device connected to the take-up roller 102 drives the take-up roller 102 to rotate, winding the nonwoven fabric onto the winding roller. After winding is completed, a new winding roller is placed on the take-up roller 102 on the other side, and then the rotating component 101 is controlled to be installed as shown. Figure 1As shown, rotating counterclockwise by 180 degrees, the rotating component 101 drives a pair of take-up rollers 102 to rotate by 180 degrees, rotating the wound nonwoven fabric to the desired position. Figure 2 The location shown Then, the lifting cylinder connected to the lifting rod 202 controls the fixed frame 201 to move upward. During the upward movement of the fixed frame 201, the guide rollers 206 on the first fixed shaft 203 and the moving shaft 205 will first touch the nonwoven fabric, and then the fixed frame 201 will move upward until the guide rollers 206 on the second fixed shaft 204 are in contact with the bottom of the take-up roller 102. During this process, after the moving shaft 205 contacts the take-up roller 102, it will rotate to one side of the first fixed shaft 203. Then, through the tension spring 209, the moving shaft 205 drives the guide rollers 206 on it to be in contact with the surface of the take-up roller 102. At this time, the cutting device 2 is in the following state: Figure 2 As shown; Subsequently, the drive device connected to the drive shaft 217 drives it to rotate. The drive shaft 217 drives the first belt gear 214 to rotate. The first belt gear 214, in conjunction with the second belt gear 215, drives the belt 216 to rotate. The belt 216 drives the slider 212 to move from one end of the slide rail 211 to the other end. When the slider 212 first starts to move, the gear 222 and the rack 224 are in a meshing state. When the slider 212 moves, the rack 224 causes the gear 222 to rotate. The gear 222 drives the knife holder 221 and the cutting blade 225 to rotate, causing the knife holder 221 and the cutting blade 225 to change from a state close to the surface of the slider 212 to a state perpendicular to the slider 212. Then the slider 212 continues to drive the knife holder 221 and the cutting blade 225 to move, so that the cutting blade 225 can cut the nonwoven fabric. After cutting, the slider 212 is driven by the belt 216 to one end close to the first belt gear 214, and the knife holder 221 and the cutting knife 225 are switched to a state close to the surface of the slider 212. At the same time as the non-woven fabric is cut, the cut non-woven fabric is rewound onto the new winding roller 102 by the second fixed shaft 204 and the moving shaft 205 for new winding. Then the fixed frame 201 is lowered to the original position.
