Description

Technical Field

[0001] This utility model relates to the technical field of edge trimming and straightening devices for wool knitted fabrics, and in particular to an edge trimming and straightening device for wool knitted fabrics. Background Technology

[0002] A wool knitted fabric trimming device is a specialized piece of equipment or machinery used to trim the edges of wool knitted fabrics. Its main function is to remove excess material from the edges of wool knitted fabrics, making the fabric edges neat, smooth, and conforming to specific dimensional requirements. In the processing of wool knitted fabrics, the trimming process is a key step in ensuring the dimensional accuracy and appearance quality of the fabric.

[0003] Traditional wool knitted fabric trimming machines typically only have a single cutting function. Due to the natural shrinkage and elasticity of wool fibers, the edge fibers are prone to loosening after ordinary trimming. Furthermore, the softness and elasticity of the knitted fabric itself make it easy to produce irregular deformations after trimming, often resulting in problems such as edge curling, frayed edges, and size deformation. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for trimming and straightening wool knitted fabrics.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a wool knitted fabric edge trimming and straightening device, comprising a machine plate, a unwinding roller rotatably connected to the machine plate, an edge trimming table fixedly connected to the machine plate, an mounting plate provided on the edge trimming table, two second motors fixedly connected to the mounting plate, two edge trimming blades rotatably connected to the mounting plate via bearings, the edge trimming blades being driven to rotate by the second motors, two limiting rollers rotatably connected to the machine plate via bearings, two fixed plates fixedly connected to the machine plate, and two traction rollers rotatably connected to the two fixed plates via bearings. A gear is fixedly connected to one end of the traction roller, and two gears mesh with each other. A first motor is fixedly connected to one of the fixed plates, and the traction roller is driven to rotate by the first motor. An edge-forming structure is provided on the edge-cutting platform. The edge-forming structure is mainly composed of a gantry frame, which is fixedly connected to the edge-cutting platform. A cylinder is fixedly connected to the gantry frame, and the piston rod of the cylinder is fixedly connected to the mounting plate. A rotating shaft is rotatably connected to the mounting plate through a bearing. Two edge-forming rollers are provided on the rotating shaft. A ceramic heating rod is fixedly connected inside the edge-forming rollers, and a connecting roller is fixedly connected to both edge-forming rollers.

[0006] The aforementioned components achieve the following effects: The wool knitted fabric roll is placed on the unwinding roller, then the fabric passes sequentially under two limiting rollers, and then between two traction rollers. The output of the first motor (model Y2-160m1-8) is connected to the traction rollers via a reducer and coupling. Starting the first motor drives one traction roller to rotate. Through the action of two gears, the two traction rollers rotate synchronously in opposite directions, pulling the fabric. When the fabric passes the edge-cutting table, the output of the second motor (model Y2-160m1-8) is connected to the edge-cutting blades via a reducer and coupling. Starting both second motors drives two edge-cutting blades to rotate, cutting the fabric on both sides. For edge trimming, the cylinder model is Rexroth VE2 / D-60. Activating the cylinder causes the piston rod to lower the mounting plate, which in turn lowers the connecting roller and the trimming roller. As the mounting plate descends, the connecting roller rolls on the fabric in the direction of fabric movement, causing the shaft to rotate. The ceramic heating rod is then activated to heat the trimming roller. This heating raises the temperature of the fibers at the edge of the wool knitted fabric, putting them in a thermoplastic state. Under the pressure of the trimming roller, the fibers undergo plastic deformation according to the shape and pressure direction of the roller, resulting in a smoother and more regular edge. This avoids the problem of the wool knitted fabric roll being placed on the unwinding roller and then passed sequentially under the two limiting rollers. Then, the fabric passes between two traction rollers. The output of the first motor is connected to the traction roller via a reducer and coupling. The first motor is model Y2-160m1-8. Starting the first motor drives one traction roller to rotate. Through the action of two gears, the two traction rollers rotate synchronously in opposite directions, pulling the fabric. When the fabric passes the edge-cutting table, the output of the second motor is connected to the edge-cutting knife via a reducer and coupling. The second motor is model Y2-160m1-8. Starting both second motors drives two edge-cutting knives to rotate, trimming both sides of the fabric. The cylinder is model Rexroth VE2 / D-60. Starting the cylinder causes the piston rod to lower the mounting plate, which in turn drives... As the connecting roller and the edging roller descend, the connecting roller rolls on the fabric along the direction of fabric movement. The rotating shaft then rotates, activating the ceramic heating rod to heat the edging roller. The heated edging roller raises the temperature of the fibers at the edge of the wool knitted fabric, putting them in a thermoplastic state. Under the pressure of the edging roller, the fibers can undergo plastic deformation according to the shape of the edging roller and the direction of pressure, making the edge smoother and more regular. This avoids the problems that arise from the natural felting and elasticity of wool fibers, which make the edge fibers prone to loosening after ordinary edge trimming. Furthermore, the softness and elasticity of the knitted fabric itself make it easy for irregular deformation to occur after edge trimming, often resulting in problems such as edge curling, frayed edges, and dimensional deformation.

[0007] Preferably, two round rods are slidably inserted into the gantry frame, and the round rods are fixedly connected to the mounting plate.

[0008] The effect achieved by the above components is that the two round rods slide at the upper limit of the gantry, making the movement of the mounting plate more stable.

[0009] Preferably, two connecting blocks are fixedly connected to the rotating shaft, the connecting blocks are slidably connected to the mounting block, and a first spring is fixedly connected to the mounting block, with one end of the first spring fixedly connected to the connecting block.

[0010] The effect achieved by the above components is as follows: when the sizing roller presses the fabric, the first spring is in a contracted state, so the rebound force of the first spring acts on the mounting block, thereby increasing the force of the sizing roller on the fabric.

[0011] Preferably, a limit block is fixedly connected to the rotating shaft, and a fixing block is fixedly connected to the mounting plate.

[0012] The effect achieved by the above components is that the fixing block can limit the limiting block and prevent the rotating shaft from rotating in the opposite direction.

[0013] Preferably, the cutting table is provided with a cleaning structure, which mainly consists of a fixed frame. The fixed frame is fixedly connected to the cutting table, and sliders are slidably connected to both sides of the fixed frame. A cleaning brush is rotatably connected to the two sliders through bearings. A third motor is fixedly connected to the fixed frame, and the cleaning brush is driven to rotate by the third motor.

[0014] The effect achieved by the above components is as follows: the third motor is started, and the output end of the third motor is connected to the cleaning brush through a reducer and a coupling. The model of the third motor is Y2-160m1-8. When the fabric passes through the cleaning brush, the slider slides down. Starting the third motor will drive the cleaning brush to rotate and clean the fabric. The cleaning brush uses anti-static nylon bristles.

[0015] Preferably, a dust conveying pipe is fixedly connected to the fixed frame, one end of the dust conveying pipe is fixedly connected to a dust collection box, and a dust collection pump is fixedly connected to the dust collection box.

[0016] The aforementioned components achieve the following effect: when the dust pump is activated, the cleaned dust and lint can be pumped through the dust conveying pipe to the dust collection bag in the dust collection box for easy collection.

[0017] Preferably, two slide rods are slidably inserted on the fixed frame, and the slide rods are fixedly connected to the slider.

[0018] The effect achieved by the above components is that sliding the two sliders can drive the slider to move.

[0019] Preferably, a second spring is sleeved on the slide rod, one end of the second spring is fixedly connected to the slide rod, and the other end of the second spring is fixedly connected to the fixed frame.

[0020] The effect achieved by the above components is that the second spring is in a stretched state during the cleaning process, so the rebound force of the second spring acts on the slide bar, and then on the cleaning brush.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, by setting an edge-aligning structure, the wool knitted fabric roll is placed on the unwinding roller, and then the fabric passes sequentially under two limiting rollers and between two traction rollers. The output end of the first motor is connected to the traction rollers through a reducer and a coupling. The first motor is model Y2-160m1-8. Starting the first motor drives one traction roller to rotate. Through the action of two gears, the two traction rollers rotate synchronously in opposite directions to pull the fabric. When the fabric passes the edge-cutting table, the output end of the second motor is connected to the edge-cutting knife through a reducer and a coupling. The second motor is model Y2-160m1-8. Starting the first motor drives one traction roller to rotate. Through the action of two gears, the two traction rollers rotate synchronously in opposite directions to pull the fabric. When the fabric passes the edge-cutting table, the output end of the second motor is connected to the edge-cutting knife through a reducer and a coupling. The second motor drives two edge-cutting blades to rotate, trimming both sides of the fabric. The cylinder model is Rexroth VE2 / D-60. Activating the cylinder causes the piston rod to lower the mounting plate, which in turn lowers the connecting roller and the edge-trimming roller. As the mounting plate descends, the connecting roller rolls on the fabric along the direction of fabric movement, causing the shaft to rotate. This activates the ceramic heating rod to heat the edge-trimming roller. The heated edge-trimming roller raises the temperature of the fibers at the edge of the wool knitted fabric, putting them in a thermoplastic state. Under the pressure of the edge-trimming roller, the fibers can plastically deform according to the shape and pressure direction of the roller, resulting in a smoother and more regular edge. This avoids the problem of the wool knitted fabric roll being placed on the unwinding roller and then... The fabric passes under two limiting rollers and then between two traction rollers. The output of the first motor (model Y2-160m1-8) is connected to the traction rollers via a reducer and coupling. Starting the first motor drives one traction roller to rotate. Through the action of two gears, the two traction rollers rotate synchronously in opposite directions, pulling the fabric. When the fabric passes the edge-cutting table, the output of the second motor (model Y2-160m1-8) is connected to the edge-cutting blades via a reducer and coupling. Starting both second motors drives two edge-cutting blades to cut the edges of the fabric. The cylinder (model Rexroth VE2 / D-60) is activated; its piston rod drives the mounting plate downwards. The lowering of the mounting plate causes the connecting roller and the edge-setting roller to descend. As the mounting plate descends, the connecting roller rolls on the fabric and rotates along the direction of fabric movement. This activates the ceramic heating rod to heat the edge-setting roller. The heated edge-setting roller raises the temperature of the fibers at the edge of the wool knitted fabric, putting them in a thermoplastic state. Under the pressure of the edge-setting roller, the fibers can undergo plastic deformation according to the shape of the roller and the direction of pressure, making the edge smoother and more regular. This avoids the problems that occur when wool fibers have natural felting and elasticity, and the edge fibers are easily loosened after ordinary edge cutting. Furthermore, the softness and elasticity of the knitted fabric itself make it easy for irregular deformation to occur after edge cutting, often resulting in problems such as edge curling, frayed edges, and dimensional deformation.

[0028] Reference Figure 3The edge trimming table 3 is equipped with an edge trimming structure 8, which mainly consists of a gantry frame 81. The gantry frame 81 is fixedly connected to the edge trimming table 3. A cylinder 82 is fixedly connected to the gantry frame 81, and the piston rod of the cylinder 82 is fixedly connected to the mounting plate 11. A rotating shaft 83 is rotatably connected to the mounting plate 11 via bearings. Two edge trimming rollers 85 are mounted on the rotating shaft 83. A ceramic heating rod is fixedly connected inside the edge trimming roller 85. A connecting roller 86 is fixedly connected to both edge trimming rollers 85. The wool knitted fabric roll is placed on the unwinding roller 2, and then the fabric is passed under the two limiting rollers 4 in sequence, and then passed between the two traction rollers 6. The output end of the first motor 10 is connected to a reducer and The coupling connects to the traction roller 6. The first motor 10, model Y2-160m1-8, drives one traction roller 6 to rotate. Through the action of two gears 7, the two traction rollers 6 rotate synchronously in opposite directions, pulling the fabric. When the fabric passes the edge-cutting table 3, the output end of the second motor 12, model Y2-160m1-8, is connected to the edge-cutting knife 13 through a reducer and coupling. Activating both second motors 12 drives two edge-cutting knives 13 to rotate, cutting the edges of both sides of the fabric. The cylinder 82, model Rexroth VE2 / D-60, drives the piston rod of cylinder 82 to move the mounting plate 11 downwards. The lowering of the mounting plate 11 causes the connecting roller 86 and the edge-setting roller 85 to descend. As the mounting plate 11 descends, the connecting roller 86 rolls on the fabric and rotates along the direction of fabric movement. This activates the ceramic heating rod to heat the edge-setting roller 85. The heated edge-setting roller 85 raises the temperature of the fibers at the edge of the wool knitted fabric, putting them in a thermoplastic state. Under the pressure of the edge-setting roller 85, the fibers can undergo plastic deformation according to the shape and pressure direction of the edge-setting roller 85, resulting in a smoother and more regular edge. This avoids the problem of the wool knitted fabric roll being placed on the unwinding roller 2, then passing the fabric sequentially under the two limiting rollers 4, and then between the two traction rollers 6. The output of the first motor 10 is connected to the traction roller 6 via a reducer and coupling. The first motor 10 is model Y2-160m1-8. Starting the first motor 10 drives one traction roller 6 to rotate. Through the action of two gears 7, the two traction rollers 6 rotate synchronously in opposite directions, pulling the fabric. When the fabric passes the edge-cutting table 3, the output of the second motor 12 is connected to the edge-cutting knife 13 via a reducer and coupling. The second motor 12 is model Y2-160m1-8. Starting both second motors 12 drives two edge-cutting knives 13 to rotate, cutting the edges of both sides of the fabric. The cylinder 82 is model Rexroth VE2 / D-60. Starting the cylinder 82...The piston rod of cylinder 82 drives the mounting plate 11 to descend, which in turn drives the connecting roller 86 and the edge-finishing roller 85 to descend. As the mounting plate 11 descends, the connecting roller 86 rolls on the fabric and rotates along the direction of fabric movement. The rotating shaft 83 rotates, activating the ceramic heating rod to heat the edge-finishing roller 85. The heated edge-finishing roller 85 raises the temperature of the fibers at the edge of the wool knitted fabric, putting them in a thermoplastic state. Under the pressure of the edge-finishing roller 85, the fibers can undergo plastic deformation according to the shape and pressure direction of the edge-finishing roller 85, making the edge smoother and more regular. This avoids the problem that wool fibers have natural felting and elasticity, making the edge fibers easy to loosen after ordinary edge cutting. Furthermore, the softness and elasticity of the knitted fabric itself make it easy to produce irregular deformation after edge cutting, often resulting in problems such as edge curling, frayed edges, and dimensional deformation. Two round rods 811 are slidably inserted on the gantry frame 81, and the round rods 811 are fixedly connected to the mounting plate 11. Two round rods 811 slide at the upper limit on the gantry frame 81, making the movement of the mounting plate 11 more stable. Two connecting blocks 87 are fixedly connected to the rotating shaft 83. The connecting blocks 87 are slidably connected to the mounting block 84. A first spring 88 is fixedly connected to the mounting block 84, and one end of the first spring 88 is fixedly connected to the connecting block 87. When the edge-trimming roller 85 presses the fabric, the first spring 88 is in a contracted state. Therefore, the rebound force of the first spring 88 acts on the mounting block 84, thereby increasing the force of the edge-trimming roller 85 on the fabric. A limit block 89 is fixedly connected to the rotating shaft 83, and a fixing block 810 is fixedly connected to the mounting plate 11. The fixing block 810 can limit the limit block 89 to prevent the rotating shaft 83 from rotating in the opposite direction.

Sliding blocks 92 are slidably connected to both sides of the fixed frame 91. Cleaning brushes 93 are connected to the two sliding blocks 92 via bearings. A third motor 94 is fixedly connected to the fixed frame 91. The cleaning brushes 93 are driven to rotate by the third motor 94, which also activates the motor. The output of the third motor 94 is connected to the cleaning brushes 93 via a reducer and coupling. The third motor 94 is a Y2-160m1-8 model. When the fabric passes through the cleaning brushes 93, the sliding blocks 92 slide downwards, and the activation of the third motor 94 drives the cleaning brushes 93 to rotate, cleaning the fabric. The cleaning brushes 93 use anti-static nylon bristles. A dust conveying pipe 98 is fixedly connected to the fixed frame 91.

One end of the second spring 96 is fixedly connected to the sliding rod 95, and the other end of the second spring 96 is fixedly connected to the fixed frame 91. During the cleaning process, the second spring 96 is in a stretched state. Therefore, the rebound force of the second spring 96 acts on the sliding rod 95, and then acts on the cleaning brush 93.

Starting the two second motors 12 can drive the two edge-cutting blades 13 to rotate, cutting the edges of both sides of the fabric. The cylinder 82 is model Rexroth VE2 / D-60. Starting the cylinder 82 causes the piston rod of the cylinder 82 to drive the mounting plate 11 to descend, which in turn drives the connecting roller 86 and the edge-trimming roller 85 to descend. As the mounting plate 11 descends, the connecting roller 86 rolls on the fabric and along the direction of fabric movement. The rotating shaft 83 rotates, activating the ceramic heating rod to heat the edge-trimming roller 85. 5. Heating is performed. The heated edge-setting roller 85 raises the temperature of the fibers at the edge of the wool knitted fabric, putting them in a thermoplastic state. Under the pressure of the edge-setting roller 85, the fibers can undergo plastic deformation according to the shape and pressure direction of the edge-setting roller 85, thus making the edge smoother and more regular. This avoids the problem of the wool knitted fabric roll being placed on the unwinding roller 2, and then the fabric is passed sequentially under the two limiting rollers 4, and then between the two traction rollers 6.
