Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, specifically a cutting device for polyester woven white fabric. Background Technology

[0002] Polyester woven grey fabric is a base fabric made of 100% polyester fiber using a weaving process without dyeing or finishing treatment.

[0003] In existing technologies, polyester woven white greige fabric is mostly cut using a cutting machine. However, during the cutting process, the fabric surface is prone to wrinkles due to external factors. If the wrinkles are not eliminated in time before cutting, the cutting accuracy will be greatly reduced. Based on this, the present invention provides a polyester woven white greige fabric cutting device to solve the problems mentioned in the background technology. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a polyester woven white fabric cutting device to solve the problem that wrinkles easily occur in the fabric during cutting, thereby reducing the cutting accuracy.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A polyester woven white fabric cutting device includes a machine body, an unwinding shaft rotatably connected between the inner surfaces of the machine body, a servo motor connected to the unwinding shaft fixedly installed on the side of the machine body, fabric wound around the periphery of the unwinding shaft, a set of guide rollers rotatably connected between the inner surfaces of the machine body, an ironing mechanism that cooperates with the fabric installed on the inner wall of the machine body, a steam generator connected to the ironing mechanism fixedly installed on the side of the machine body, the periphery of the ironing mechanism being drivenly connected to the unwinding shaft, a material stacking mechanism fixedly installed at the tail of the machine body, a cutting mechanism installed between the inner surfaces of the machine body and adjacent to the material stacking mechanism, a flattening mechanism installed between the inner surfaces of the machine body and adjacent to the cutting mechanism, a first air pump and a second air pump fixedly installed on the end face of the machine body respectively, one end of the air outlet of the first air pump and the second air pump being fixedly connected to the flattening mechanism, and a wind pressure mechanism installed at the tail of the cutting mechanism.

[0006] The beneficial effects of this utility model are:

[0007] 1) By designing ironing and flattening mechanisms, an ironing and stretching / flattening mechanism is added to the traditional cutting device before fabric cutting. When the fabric is delivered, the ironing mechanism can iron the fabric with steam, while the stretching / flattening mechanism can effectively eliminate wrinkles on the fabric surface by applying strong tension. Through the above wrinkle removal effect, the cutting accuracy of this device when cutting polyester woven white fabric is effectively improved. Moreover, during the cutting operation, the ironing and stretching / flattening mechanisms can work synchronously and in conjunction with each other. Through the realization of synchronous and in conjunction with each other, the automation level of this device and the integration of the process are effectively improved. Through the design of the air pressure mechanism, the cut fabric can be pressed tightly on the stacking table. Through the effect of pressing the fabric on the stacking table, the neatness of the stacked fabric after cutting is effectively improved.

[0008] 2) The design of the forward and reverse ironing tables allows the steam generator to supply steam to both tables during operation. When the unwinding shaft is working, the drive wheel and driven wheel are linked to it. After the drive wheel operates, it rotates forward and backward within a set cycle. After the drive wheel rotates forward and backward, it drives the annular drive belt to rotate forward and backward within a set stroke. After the annular drive belt rotates forward and backward, it drives the forward and reverse ironing tables to reciprocate linearly within a set cycle. The reciprocating motion of the forward and reverse ironing tables is in opposite directions. When the forward and reverse ironing tables are working, the steam nozzles supply steam to the surface of the fabric, thus achieving steam ironing. When the unwinding shaft is working, the exhaust component works synchronously. After the exhaust component operates, it discharges the excess steam generated by the ironing mechanism. At the same time, the exhaust component can also cool and shape the ironed fabric.

[0009] 3) The design of two clamping components allows the fabric to be clamped and limited on both sides by the two clamping components. After the two clamping components clamp the fabric, the first air pump supplies air to a set of pneumatic push rods. After the set of pneumatic push rods is supplied with air, the distance between the two clamping components is changed. After the distance between the two clamping components is changed, a preset degree of stretching and flattening force is applied from both sides of the fabric. By applying the stretching and flattening force, the fabric can be stretched and flattened. When the monitoring value of the air pressure sensor at the first air pump reaches the set threshold, the first air pump stops working. By achieving the stretching and flattening effect of the fabric, the probability of wrinkles appearing on the fabric surface is effectively reduced.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the ironing mechanism includes a base frame, an annular drive belt, and an exhaust assembly. Both sides of the base frame and the exhaust assembly are fixedly connected to the machine body. The peripheral side of the exhaust assembly is driven by the unwinding shaft. A driving wheel and a driven wheel are actively connected between the inner surfaces of the base frame. The peripheral sides of both the driving wheel and the driven wheel are driven by the annular drive belt. The surface of the driving wheel is driven by the unwinding shaft through a linkage assembly. Two symmetrically arranged guide rods a are fixedly installed between the inner surfaces of the base frame. A forward ironing table and a reverse ironing table are slidably connected to the inner wall of the base frame through the two guide rods a. The inner walls of both the forward and reverse ironing tables are fixedly connected to an annular drive belt. A set of heating rods arranged in a linear array are fixedly installed inside both the forward and reverse ironing tables. A set of guide rollers are installed with preheating rods inside each of them. Two symmetrically arranged air-distributing chambers connected by connecting pipes are opened inside both the forward and reverse ironing tables. The peripheral sides of the two connecting pipes are fixedly connected to a steam generator through corrugated metal hoses. Two sets of symmetrically arranged steam nozzles connected to the air-distributing chambers are opened inside both the forward and reverse ironing tables. Both the forward and reverse ironing tables are made of metal.

[0012] The beneficial effects of adopting the above-mentioned further solution are that, during operation, the steam generator operates in a set state, thereby supplying steam to the forward and reverse ironing tables. When the unwinding shaft is working, the drive wheel and the driven wheel are linked with the unwinding shaft. After the drive wheel works, it then rotates forward and backward within a set cycle. After the drive wheel rotates forward and backward, it then drives the annular drive belt to rotate forward and backward within a set stroke. After the annular drive belt rotates forward and backward, it then drives the forward and reverse ironing tables to reciprocate linearly within a set cycle. The reciprocating motion of the forward and reverse ironing tables is in opposite directions. When the forward and reverse ironing tables are working, the steam nozzles supply steam to the surface of the fabric, thereby realizing steam ironing. When the unwinding shaft is working, the exhaust component works synchronously. After the exhaust component works, it then discharges the excess steam generated by the ironing mechanism. At the same time, after the exhaust component works, it can also cool and shape the ironed fabric.

[0013] Furthermore, the linkage assembly includes a slide groove, a drive gear plate, an eccentric wheel, and a coupling formed inside the machine body. The peripheral side of the drive gear plate is slidably connected to the slide groove, the peripheral side of the eccentric wheel is fixedly connected to the unwinding shaft, a connecting rod is hinged between the opposing surfaces of the eccentric wheel and the drive gear plate, the peripheral side of the coupling is rotatably connected to the machine body, the bottom end of the coupling is fixedly connected to the drive wheel, and a driven gear that meshes with the drive gear plate is fixedly installed on the peripheral side of the coupling.

[0014] The beneficial effect of adopting the above-mentioned further solution is that, during operation, driven by the servo motor, the unwinding shaft releases the fabric wound around its periphery at a set speed. When the unwinding shaft is working, it then drives the eccentric wheel to rotate in a circular motion. After the eccentric wheel rotates in a circular motion, it then drives the drive tooth plate to reciprocate linearly along the slide groove direction through the connecting rod. After the drive tooth plate reciprocates linearly, it then drives the coupling to rotate reciprocally. After the coupling reciprocates, it then drives the drive wheel to rotate. After the drive wheel reciprocates, it then drives the forward ironing table and the reverse ironing table to reciprocate linearly within a set cycle.

[0015] Furthermore, the exhaust assembly includes a top frame and a drive shaft. Both sides of the top frame are fixedly connected to the machine body. A set of axial flow exhaust fans arranged in a linear array are fixedly installed on the inner wall of the top frame. Both ends of the drive shaft are rotatably connected to the machine body. The circumferential side of the drive shaft is connected to the unwinding shaft via a chain. Each axial flow exhaust fan has a driven bevel gear fixedly installed at its rotating shaft end.

[0016] The beneficial effect of adopting the above-mentioned further solution is that when the servo motor drives the unwinding shaft to work, the unwinding shaft drives the transmission shaft to rotate synchronously through the chain. Due to the meshing connection design of the transmission bevel gear and the driven bevel gear, the transmission shaft drives a set of axial flow exhaust fans to work at the same speed, and then performs exhaust operations.

[0017] Furthermore, a transmission bevel gear that mates with the driven bevel gear is fixedly installed on the circumferential side of the transmission shaft and at the position corresponding to each driven bevel gear, and the top frame is located directly above the ironing mechanism.

[0018] The beneficial effect of adopting the above-mentioned further solution is that when the drive shaft rotates, the axial flow exhaust fan is effectively driven through the meshing connection design between the driven bevel gear and the drive bevel gear.

[0019] Furthermore, the cutting mechanism includes a set of pressure push rods, the peripheral surfaces of which are fixedly connected to the machine body. A knife holder is fixedly installed at the bottom end of the set of pressure push rods, and a cutting knife is fixedly installed on the bottom surface of the knife holder. A knife groove is fixedly opened inside the machine body at a position directly below the cutting knife. The air pressure mechanism includes an air box, the surface of which is fixedly connected to the machine body. A set of fabric pressing fans arranged in a linear array with a vertical downward air outlet direction is fixedly installed inside the air box. A filter plate is installed on the top surface of the air box at a position corresponding to each fabric pressing fan, and the surface of the filter plate has filter holes.

[0020] The beneficial effect of adopting the above-mentioned further solution is that, during use, the controller paired with the device controls the pressure push rod to reciprocate linearly within a set cycle. After the pressure push rod moves downward, it drives the cutter to cut the fabric. By controlling the motion cycle of the pressure push rod, the cutting length of the fabric can be effectively controlled. When the air pressure mechanism is working, a set of fabric pressing fans blow air downward in a set state. After the fabric pressing fans blow air downward, the cut fabric is pressed tightly against the stacking mechanism. By achieving the effect of the fabric pressing tightly against the stacking platform, the limiting effect of the fabric on the stacking platform and the stability of the fabric after cutting are effectively guaranteed.

[0021] Furthermore, the stacking mechanism includes a stacking platform and a set of lifting push rods. The top ends of the set of lifting push rods are fixedly connected to the stacking platform, the peripheral side of the stacking platform is slidably connected to the machine body, and the bottom ends of the set of lifting push rods are fixedly connected to the machine body.

[0022] The beneficial effect of adopting the above-mentioned further solution is that, during operation, the stacking table stacks and receives the cut fabric. During the stacking process, the lifting push rod works periodically. Within the working cycle of the lifting push rod, the lifting push rod drives the stacking table to move down a specified stroke. Through the above-mentioned working state settings, the stacking table can continuously stack the fabric.

[0023] Furthermore, the flattening mechanism includes two symmetrically arranged clamping components and two symmetrically arranged guide rods b. Both ends of the two guide rods b are fixedly connected to the machine body. The inner walls of the two clamping components are slidably connected to the guide rods b. A set of pneumatic push rods is fixedly installed between the opposing surfaces of the two clamping components. One end of the air outlet of the first air pump is fixedly connected to the set of pneumatic push rods through a hose a. One end of the air outlet of the second air pump is fixedly connected to the two clamping components through a hose b. A pressure sensor is fixedly installed at one end of the air outlets of the first and second air pumps.

[0024] The beneficial effect of adopting the above-mentioned further solution is that, during use, the two clamping components clamp the fabric from both sides. After the two clamping components clamp the fabric, the first air pump supplies air to a set of pneumatic push rods. After the set of pneumatic push rods is supplied with air, the distance between the two clamping components is changed. After the distance between the two clamping components is changed, the fabric is stretched and flattened from both sides. When the monitoring value of the air pressure sensor at the first air pump reaches the set threshold, the first air pump stops working. By achieving the effect of stretching and flattening the fabric, the probability of wrinkles appearing on the fabric surface is effectively reduced.

[0025] Furthermore, the clamping assembly includes a fixed clamping frame and a movable clamping frame. The inner wall of the fixed clamping frame is slidably connected to the guide rod b. The surface of the fixed clamping frame is fixedly connected to a set of pneumatic push rods. A set of guide rods c are fixedly installed on the top surface of the movable clamping frame. The peripheral side of each guide rod c is slidably connected to the fixed clamping frame. A transmission module is fixedly installed inside both the fixed clamping frame and the movable clamping frame. An annular flattening clamping strap is connected to the peripheral side of both transmission modules. A pressure airbag is fixedly installed between the opposing surfaces of the fixed clamping frame and the movable clamping frame. The top of the pressure airbag is fixedly connected to a second air pump through a hose b. A shaping spring is fixedly installed inside the pressure airbag. The shape of the shaping spring is adapted to the shape of the pressure airbag.

[0026] The beneficial effect of adopting the above-mentioned further solution is that after the positions of the two clamping components are adjusted to the two sides of the fabric, the second air pump works. After the second air pump works, it then supplies air to the pressure airbags in the two clamping components. After the pressure airbags are supplied with air, the two annular flattening clamps are brought close together. After the two annular flattening clamps are brought close together, they then perform a tight clamping operation on the fabric. After clamping, the two clamping components stretch the fabric in the horizontal direction under the action of the pneumatic push rod.

[0027] Furthermore, the transmission module includes a transmission motor, a driving roller, and a driven roller. The output shaft of the transmission motor is fixedly connected to the driving roller, and the peripheral surfaces of the driving roller and the driven roller are both connected to an annular flattening belt drive.

[0028] The beneficial effect of adopting the above-mentioned further solution is that after the two clamping components clamp the fabric tightly, the transmission modules in the two clamping components work synchronously. After the two transmission modules work, they drive the fabric to move towards the cutting mechanism at a set speed. Attached Figure Description

[0038] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0039] The present invention provides the following preferred embodiments:

[0040] like Figure 1-7 As shown, a polyester woven white fabric cutting device includes a machine body 1, an unwinding shaft 2 rotatably connected between the inner surfaces of the machine body 1, a servo motor 3 connected to the unwinding shaft 2 fixedly installed on the side of the machine body 1, fabric wound around the periphery of the unwinding shaft 2, a set of guide rollers 4 rotatably connected between the inner surfaces of the machine body 1, each of the guide rollers 4 having a preheating rod 37 installed inside, and an ironing mechanism that cooperates with the fabric installed on the inner wall of the machine body 1. The ironing mechanism is designed to perform bidirectional ironing on the surface of the fabric, thereby reducing the probability of wrinkles appearing on the surface of the fabric during cutting.

[0041] A steam generator 5, which is connected to the ironing mechanism, is fixedly installed on the side of the body 1. When the steam generator 5 is working, it supplies steam for ironing to the ironing mechanism.

[0042] The ironing mechanism is connected to the unwinding shaft 2 via a transmission. A material stacking mechanism is fixedly installed at the tail of the machine body 1. A cutting mechanism is installed between the inner surfaces of the machine body 1 and at positions adjacent to the material stacking mechanism. A flattening mechanism is installed between the inner surfaces of the machine body 1 and at positions adjacent to the cutting mechanism. A first air pump 7 and a second air pump 8 are fixedly installed on the end faces of the machine body 1, respectively. One end of the air outlet of the first air pump 7 and the second air pump 8 is fixedly connected to the flattening mechanism. A wind pressure mechanism is installed at the tail of the cutting mechanism.

[0043] In this embodiment, as Figure 4-5 As shown, the ironing mechanism includes a base frame 9, an annular drive belt 10, and an exhaust assembly. Both sides of the base frame 9 and the exhaust assembly are fixedly connected to the machine body 1. The peripheral side of the exhaust assembly is driven by the unwinding shaft 2. The inner surfaces of the base frame 9 are actively connected to a drive wheel 6 and a driven wheel 11. The peripheral sides of the drive wheel 6 and the driven wheel 11 are driven by the annular drive belt 10. The axes of the drive wheel 6 and the driven wheel 11 are perpendicular to the axis of the unwinding shaft 2.

[0044] The surface of the drive wheel 6 is connected to the unwinding shaft 2 via a linkage assembly. Two symmetrically arranged guide rods a12 are fixedly installed between the inner surfaces of the bottom frame 9. The axis of the guide rods a12 is parallel to the axis of the unwinding shaft 2.

[0045] The inner wall of the bottom frame 9 is slidably connected to the forward ironing table 13 and the reverse ironing table 14 by two guide rods a12 respectively. The bottom frame 9 is fixedly installed with pressure plates at the positions corresponding to the forward ironing table 13 and the reverse ironing table 14.

[0046] The inner walls of both the forward ironing table 13 and the reverse ironing table 14 are fixedly connected to the annular drive belt 10. A set of electric heating rods 15 arranged in a linear array are fixedly installed inside both the forward ironing table 13 and the reverse ironing table 14. When the electric heating rods 15 are working, they are equipped with a temperature control circuit or a temperature control resistor. Through the design of the temperature control circuit or the temperature control resistor, the electric heating rods 15 can perform constant temperature heating operations on the forward ironing table 13 and the reverse ironing table 14.

[0047] Both the forward ironing table 13 and the reverse ironing table 14 have two symmetrically arranged air distribution chambers connected by connecting pipes. The periphery of the two connecting pipes is fixedly connected to the steam generator 5 through corrugated metal hoses. Both the forward ironing table 13 and the reverse ironing table 14 have two sets of symmetrically arranged steam nozzles 16 connected to the air distribution chambers. Both the forward ironing table 13 and the reverse ironing table 14 are made of metal.

[0048] During operation, the steam generator 5 operates in a set state, supplying steam to the forward ironing table 13 and the reverse ironing table 14. When the unwinding shaft 2 operates, the drive wheel 6 and the driven wheel 11 are linked with the unwinding shaft 2. After the drive wheel 6 operates, it rotates forward and backward within a set cycle. After the drive wheel 6 rotates forward and backward, it drives the annular drive belt 10 to rotate forward and backward within a set stroke. After the annular drive belt 10 rotates forward and backward, it drives the forward ironing table 13 and the reverse ironing table 14 to reciprocate linearly within a set cycle. The reciprocating motion directions of the forward ironing table 13 and the reverse ironing table 14 are opposite. When the forward ironing table 13 and the reverse ironing table 14 are operating, the steam nozzles 16 supply steam to the surface of the fabric, thereby realizing steam ironing. When the unwinding shaft 2 operates, the exhaust component operates synchronously. After the exhaust component operates, it discharges the excess steam generated by the ironing mechanism. At the same time, after the exhaust component operates, it can also cool and shape the ironed fabric.

[0049] In this embodiment, as Figure 1 and Figure 3 As shown, the linkage assembly includes a slide 17, a drive gear plate 18, an eccentric wheel 19, and a coupling 20, all located inside the machine body 1. The circumferential side of the drive gear plate 18 is slidably connected to the slide 17. The circumferential side of the eccentric wheel 19 is fixedly connected to the unwinding shaft 2. A connecting rod 21 is hinged between the opposing surfaces of the eccentric wheel 19 and the drive gear plate 18. The circumferential side of the coupling 20 is rotatably connected to the machine body 1. The bottom end of the coupling 20 is fixedly connected to the drive wheel 6. A driven gear that meshes with the drive gear plate 18 is fixedly installed on the circumferential side of the coupling 20.

[0050] During operation, driven by the servo motor 3, the unwinding shaft 2 releases the fabric wound around its periphery at a set rate. When the unwinding shaft 2 is working, it drives the eccentric wheel 19 to rotate in a circular motion. After the eccentric wheel 19 rotates in a circular motion, it drives the drive tooth plate 18 to reciprocate linearly along the slide groove 17 via the connecting rod 21. After the drive tooth plate 18 reciprocates linearly, it drives the coupling 20 to rotate reciprocally. After the coupling 20 rotates reciprocally, it drives the drive wheel 6 to rotate. After the drive wheel 6 reciprocates, it drives the forward ironing table 13 and the reverse ironing table 14 to reciprocate linearly within a set cycle.

[0051] In this embodiment, as Figure 1 and Figure 2 As shown, the exhaust assembly includes a top frame 22 and a drive shaft 23. Both sides of the top frame 22 are fixedly connected to the body 1. A set of axial flow exhaust fans 24 arranged in a linear array are fixedly installed on the inner wall of the top frame 22. Both ends of the drive shaft 23 are rotatably connected to the body 1. The circumferential side of the drive shaft 23 is connected to the unwinding shaft 2 via a chain. Each axial flow exhaust fan 24 has a driven bevel gear fixedly installed at the shaft end.

[0052] When the servo motor 3 drives the unwinding shaft 2 to work, the unwinding shaft 2 synchronously drives the transmission shaft 23 to rotate through the chain. Due to the meshing connection design of the transmission bevel gear and the driven bevel gear, the transmission shaft 23 drives a set of axial flow exhaust fans 24 to work at the same speed, and then performs exhaust operations.

[0053] In this embodiment, as Figure 1 and Figure 2 As shown, a transmission bevel gear that mates with the driven bevel gear is fixedly installed on the circumferential side of the transmission shaft 23 and at the position corresponding to each driven bevel gear. The top frame 22 is located directly above the ironing mechanism.

[0054] When the drive shaft 23 rotates, the driven bevel gear and the drive bevel gear mesh with each other to effectively drive the axial flow exhaust fan 24.

[0055] In this embodiment, as Figure 1 and Figure 4 As shown, the cutting mechanism includes a set of pressure push rods 25. The periphery of the set of pressure push rods 25 is fixedly connected to the machine body 1. A knife holder is fixedly installed at the bottom of the set of pressure push rods 25. A cutting knife 26 is fixedly installed on the bottom surface of the knife holder. A knife groove is fixedly opened inside the machine body 1 at the position directly below the cutting knife 26. The air pressure mechanism includes a wind box 39. The surface of the wind box 39 is fixedly connected to the machine body 1. A set of fabric pressing fans 40 arranged in a linear array with the air outlet direction vertically downward is fixedly installed inside the wind box 39. A filter plate 38 is installed on the top surface of the wind box 39 at the position corresponding to each fabric pressing fan 40. The surface of the filter plate 38 has filter holes.

[0056] In use, the controller paired with the device controls the pressure push rod 25 to reciprocate linearly within a set cycle. After the pressure push rod 25 moves downward, it drives the cutter 26 to cut the fabric. By controlling the movement cycle of the pressure push rod 25, the cutting length of the fabric can be effectively controlled. When the air pressure mechanism is working, a set of fabric pressing fans 40 blows air downward in a set state. After the fabric pressing fans 40 blow air downward, the cut fabric is pressed tightly against the stacking mechanism. By achieving the effect of the fabric pressing tightly against the stacking table 27, the limiting effect of the fabric on the stacking table 27 and the stability of the fabric after cutting are effectively guaranteed.

[0057] In this embodiment, as Figure 1 and Figure 4 As shown, the material stacking mechanism includes a material stacking platform 27 and a set of lifting push rods 28. The top ends of the set of lifting push rods 28 are fixedly connected to the material stacking platform 27, the peripheral side of the material stacking platform 27 is slidably connected to the machine body 1, and the bottom ends of the set of lifting push rods 28 are fixedly connected to the machine body 1.

[0058] During operation, the stacking table 27 stacks and receives the cut fabric. During the stacking process, the lifting push rod 28 works periodically. Within the working cycle of the lifting push rod 28, the lifting push rod 28 drives the stacking table 27 to move down a specified stroke. Through the above working state settings, the stacking table 27 can continuously stack the fabric.

[0059] In this embodiment, as Figure 1 , Figure 6 and Figure 7 As shown, the flattening mechanism includes two symmetrically arranged clamping components and two symmetrically arranged guide rods b29. Both ends of the two guide rods b29 are fixedly connected to the body 1. The inner walls of the two clamping components are slidably connected to the guide rods b29. A set of pneumatic push rods 30 are fixedly installed between the opposite surfaces of the two clamping components. One end of the air outlet of the first air pump 7 is fixedly connected to the set of pneumatic push rods 30 through a hose a. One end of the air outlet of the second air pump 8 is fixedly connected to the two clamping components through a hose b. A pressure sensor is fixedly installed at one end of the air outlet of both the first air pump 7 and the second air pump 8.

[0060] In use, the two clamping components clamp the fabric from both sides. After the two clamping components clamp the fabric, the first air pump 7 supplies air to a set of pneumatic push rods 30. After the set of pneumatic push rods 30 is supplied with air, the distance between the two clamping components is changed. After the distance between the two clamping components is changed, the fabric is stretched and flattened from both sides. When the monitoring value of the air pressure sensor at the first air pump 7 reaches the set threshold, the first air pump 7 stops working. By achieving the effect of stretching and flattening the fabric, the probability of wrinkles appearing on the fabric surface is effectively reduced.

[0061] In this embodiment, as Figure 1 , Figure 6 and Figure 7 As shown, the clamping assembly includes a fixed clamping frame 31 and a movable clamping frame 32. The inner wall of the fixed clamping frame 31 is slidably connected to the guide rod b29. The surface of the fixed clamping frame 31 is fixedly connected to a set of pneumatic push rods 30. A set of guide rods c33 is fixedly installed on the top surface of the movable clamping frame 32. The peripheral side of each guide rod c33 is slidably connected to the fixed clamping frame 31. A transmission module 34 is fixedly installed inside both the fixed clamping frame 31 and the movable clamping frame 32. An annular flattening clamping strap 35 is connected to the peripheral side of both transmission modules 34. A pressure airbag 36 is fixedly installed between the opposing surfaces of the fixed clamping frame 31 and the movable clamping frame 32. The top of the pressure airbag 36 is fixedly connected to the second air pump 8 through a hose b. A plastic spring is fixedly installed inside the pressure airbag 36. The shape of the plastic spring is adapted to the shape of the pressure airbag 36.

[0062] After the two clamping components are positioned on both sides of the fabric, the second air pump 8 starts working. After the second air pump 8 starts working, it supplies air to the pressure airbags 36 in the two clamping components. After the pressure airbags 36 are supplied with air, the two annular flattening clamping straps 35 are brought close together. After the two annular flattening clamping straps 35 are brought close together, they then clamp the fabric tightly. After clamping, the two clamping components stretch the fabric horizontally under the action of the pneumatic push rod 30.

[0063] In this embodiment, as Figure 7 As shown, the transmission module 34 includes a transmission motor, a driving roller, and a driven roller. The output shaft of the transmission motor is fixedly connected to the driving roller, and the peripheral surfaces of the driving roller and the driven roller are both connected to the annular flattening belt 35.

[0064] After the two clamping components clamp the fabric tightly, the transmission modules 34 in the two clamping components work synchronously. After the two transmission modules 34 work, they drive the fabric to move towards the cutting mechanism at a set speed.

[0065] The specific steps for using this utility model are as follows:

[0066] This device is mainly suitable for cutting polyester woven white fabric. During the cutting operation, the fabric to be cut is wound on the unwinding shaft 2. During the cutting operation, the working cycle of the pressure push rod 25 is controlled by the controller matched with this device. The cutting length of the fabric is controlled by the working cycle of the pressure push rod 25. During the cutting operation, the unwinding shaft 2 releases the fabric at a set speed. The annular flattening clamp 35 works at the same speed as the unwinding shaft 2. After the unwinding shaft 2 works, the fabric is released. When the fabric is released, the ironing mechanism irons the fabric flat. The exhaust component discharges the exhaust steam generated by the ironing mechanism. At the same time, the ironed fabric is cooled and shaped. After cooling and shaping, the fabric is stretched and flattened by the flattening mechanism. The flattened fabric enters the cutting blade 26 for cutting. The cut fabric is collected by the stacking mechanism.

[0067] In summary, the beneficial effects of this utility model are specifically reflected in the design of the ironing mechanism and the flattening mechanism. Based on the traditional cutting device, an ironing mechanism and a stretching and flattening mechanism are added for cutting the fabric before cutting. When the fabric is delivered, the ironing mechanism can iron the fabric with steam, while the stretching and flattening mechanism can effectively eliminate wrinkles on the fabric surface by applying strong tension to the fabric. Through the above wrinkle removal effect, the cutting accuracy of this device when cutting polyester woven white fabric is effectively improved.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
