The collection device includes a fan, an air duct, and a collection box with an inner cavity. The collection box has an air inlet and an air outlet communicating with the inner cavity. One end of the air duct is connected to the air outlet of the fan, and the other end is connected to the air inlet of the collection box.

Description

Technical Field

[0001] This invention relates to the field of nonwoven fabric winding, and in particular to a nonwoven fabric winding device. Background Technology

[0002] A slitting machine is a mechanical device that cuts wide nonwoven fabrics, paper, mica tape, or film into multiple narrow strips. Typically, a slitting machine includes an unwinding section, a cutting section, and a winding section. After the nonwoven fabric is unwound by the unwinding section, the cutting section cuts the entire piece of nonwoven fabric into strips, and then the winding section rewinds the cut nonwoven fabric. The excess material at the edges after cutting is considered waste, which operators need to collect.

[0003] Utility model patent CN216863177U discloses a nonwoven fabric slitting machine, including a frame, a take-up roller rotatably mounted on the frame, a dividing roller rotatably mounted on the frame below the take-up roller, and a cutting device mounted on the frame between the dividing roller and the take-up roller. The cutting device includes a cutting roller and several circular cutters. The cutting roller is mounted on the frame between the take-up roller and the dividing roller, and the cutters are slidably mounted on the frame and arranged along the length of the cutting roller. The cutting edge of the cutter abuts against the side wall of the cutting roller. The cutting device also includes a driving mechanism, which includes several first cylinders. The first cylinders are slidably mounted on the frame along the axial direction of the cutting roller, and the cutters are mounted on the piston rods of the first cylinders.

[0004] The above-mentioned technical solutions have the following defects: the waste generated after the nonwoven fabric slitting machine cuts the fabric needs to be collected by the operator using an external box. At the same time, since the strip-shaped waste is relatively light, it is greatly affected by the environment and is more likely to fly up. It may also be rolled into the cutting device and cut again, affecting the normal winding of the cut nonwoven fabric. Summary of the Invention

[0005] To better collect the waste material after cutting, this application provides a nonwoven fabric winding device.

[0006] The nonwoven fabric winding device provided in this application adopts the following technical solution:

[0007] A nonwoven fabric winding device includes a frame, on which a cutting device for cutting nonwoven fabric and a winding device for winding the cut nonwoven fabric are provided. It also includes a collection device for collecting waste material. The collection device includes a fan, an air duct, and a collection box with an inner cavity. The collection box has an air inlet and an air outlet communicating with the inner cavity. The air duct is mounted on the frame, with one end connected to the air outlet of the fan and the other end connected to the air inlet of the collection box. A feed inlet for strip-shaped waste material is provided on the side wall of the air duct, allowing the strip-shaped waste material to enter the collection box through the feed inlet and the air duct.

[0008] By adopting the above technical solution, the air duct can guide the air blown out by the fan. The strip-shaped waste enters the collection box from the inlet through the air duct. This restricts the movement path of the strip-shaped waste. At the same time, the way the strip-shaped waste is blown by the wind is relatively gentle, which makes it less likely to break the strip-shaped waste. Even if it breaks, it will not affect the next strip-shaped waste being blown into the collection box. This avoids the situation where the strip-shaped waste is caught in the cutting device due to its unpredictable nature, and can better collect the cut waste.

[0009] Preferably, the air inlet is located at the top of the collection box, and the air outlet is located on the side wall of the top of the collection box;

[0010] The collection box is equipped with a compression device for compressing the waste material inside the collection box. The compression device includes a first cylinder and a pressure plate. The first cylinder is mounted on the collection box, and the piston rod of the first cylinder is mounted on the pressure plate, driving the pressure plate to slide vertically within the inner cavity. The pressure plate is used to compress the waste material inside the collection box. The pressure plate is located outside the air inlet and does not obstruct the air inlet.

[0011] By adopting the above technical solution, since the non-woven fabric waste is collected in a relatively loose state in the collection box, the non-woven fabric will fill the collection box after a period of collection, making it difficult for subsequent non-woven fabric waste to enter the collection box and affecting the continuous collection of the collection box; by using the first cylinder to drive the pressure plate to compress the non-woven fabric waste already collected in the collection box, space can be left for the collection box to continuously collect non-woven fabric waste.

[0012] Preferably, the compression device further includes a flap, one end of which is provided with a rotating shaft. The rotating shaft rotates on the pressure plate along the horizontal axis. When the flap rotates to a horizontal state, the flap is located directly below the air inlet. A torsion spring is installed on the rotating shaft, which drives the rotating shaft to rotate in the direction where the flap is in a horizontal state. When the flap is not subjected to external force, the flap rotates to abut against the pressure plate. The flap is horizontally positioned and faces the air inlet.

[0013] By adopting the above technical solution, and by setting a flap, when the collection box is not in use, the flap can rotate under the action of the torsion spring to block the air inlet, which can prevent foreign objects from entering the collection box from the air inlet. When the collection box is used to collect non-woven fabric waste, the air at the air inlet blows directly onto the flap, and the wind force drives the flap to rotate, so that the non-woven fabric waste can enter the lower part of the inner cavity through the gap between the flap and the inner wall of the inner cavity. This can prevent the wind from blowing directly onto the non-woven fabric in the collection box and prevent the compressed non-woven fabric waste in the collection box from being blown away. When the pressure plate is pressed down, the flap abuts against the non-woven fabric waste and can press the non-woven fabric waste, which can increase the pressing area of ​​the non-woven fabric waste. At the same time, the wind blowing on the flap can help the flap to press down.

[0014] Preferably, the compression device further includes a baffle located above the pressure plate. The baffle is vertically disposed on the end of the pressure plate near the flip plate. The baffle slides vertically on the collection box, and the top of the baffle extends out of the collection box. The baffle divides the space above the pressure plate and the flip plate in the inner cavity into two chambers. The baffle is used to prevent waste from entering the chamber directly above the pressure plate.

[0015] By adopting the above technical solution, during the pressing process of the pressure plate and the flip plate, non-woven fabric waste will still continuously enter the inner cavity. At this time, the baffle can separate these subsequently entering non-woven fabric wastes and prevent the wastes from entering the chamber directly above the pressure plate. In this way, during the resetting process of the pressure plate and the flip plate, the wastes accumulated above the flip plate will enter the inner cavity below the flip plate as the flip plate is opened, without affecting the collection of non-woven fabric wastes.

[0016] Preferably, it also includes a detection element, which is used to detect whether the waste collected in the collection box is full. The detection element is a filter screen, which is set at the air outlet. When the waste fills the inner cavity, the waste located at the top of the inner cavity is adsorbed on the filter screen.

[0017] By adopting the above technical solution, there will be debris on the cut non-woven fabric. This debris will be discharged into the room with the airflow from the air outlet, which will affect the respiratory health of the operators. The filter screen can block this debris and prevent it from being discharged into the room. At the same time, when the waste fills the inner cavity, the waste located in the upper part of the inner cavity near the air outlet will be adsorbed on the filter screen by the suction of the airflow at the air outlet. The operator can observe whether there is non-woven fabric attached to the filter screen from the air outlet and can judge whether the inner cavity is full of waste by sensing the change in the airflow from the air outlet. If a compression device is needed to compress it.

[0018] Preferably, it further includes a control switch, a first spring, and a fixing block. The control switch is used to control the operation of the first cylinder. A slider is provided on the filter screen. The slider slides in the air outlet from the side close to the inner cavity to the side away from the inner cavity. The fixing block is fixed on the inner wall of the air outlet, and the slider is positioned directly opposite the fixing block. The fixing block is located on the side of the filter screen away from the inner cavity. A groove is formed on the side of the fixing block facing the filter screen. The two ends of the first spring are respectively fixed on the bottom wall of the groove and the slider. The control switch is provided on the side of the fixing block facing the filter screen.

[0019] The side of the pressure plate facing the filter screen abuts against the inner wall of the cavity. When the waste fills the inner cavity, the slider moves to abut against the control switch. The control switch controls the first cylinder to run once. The side of the filter screen near the inner cavity is flush with the side of the pressure plate facing the filter screen.

[0020] By adopting the above technical solution, when the waste fills the inner cavity, the waste near the air outlet will be adsorbed onto the filter screen, clogging it. The force on the filter screen will increase, and the filter screen will move towards the control switch until the slider abuts against the control switch, thereby driving the first cylinder to run. During the operation of the first cylinder, the pressure plate will abut against the filter screen, scraping off the waste adhering to the filter screen. At the same time, the debris adhering to the filter screen will also be scraped off along with the waste. Compared with using the pressure plate alone to scrape off the debris, the waste can be used to clean the mesh of the filter screen better, improving the cleaning effect of the filter screen.

[0021] Preferably, the pressure plate has chamfered edges on its upper and lower sides near the filter screen, and the chamfer is used to abut against the slider or filter screen extending into the inner cavity.

[0022] By adopting the above technical solution, the pressure plate can move towards the air outlet side without being disturbed by the slider and filter screen located in the inner cavity during the sliding process.

[0023] Preferably, the filter screen is provided with a pull rope, the end of the pull rope away from the filter screen extends out of the air outlet and is fixed with a pull ring, the pull ring can be blown by the air blown out of the air outlet.

[0024] By adopting the above technical solution, the operator can control the start of the first cylinder by pulling the pull ring. The pull ring is equivalent to a switch that can be controlled by the operator. At the same time, the pull ring can be blown by the wind, which makes it easier for the operator to observe the air outlet more intuitively and judge the collection situation in the inner cavity.

[0025] Preferably, the bottom of the collection box has a discharge port, and a sliding plate for blocking the discharge port is provided at the discharge port.

[0026] By adopting the above technical solution, the waste in the collection box can automatically fall down by the operator pulling open the pull plate, which facilitates the use of the collection device.

[0027] Preferably, the winding device includes a first motor and a winding roller, the winding roller rotating on the frame, the first motor being mounted on the frame and driving the winding roller to rotate, and a transmission belt connected to the output shaft of the first motor, the transmission belt being wound around the output shaft of the first motor and the input shaft of the fan.

[0028] By adopting the above technical solution, while the first motor drives the winding roller to rotate, the output shaft of the first motor will drive the input shaft of the fan to rotate through the transmission belt, so as to realize the synchronous operation of the fan and the winding device, save power source, and the operator no longer needs to turn off the fan separately, thus improving work efficiency.

[0029] The main technical effects of this invention are reflected in the following aspects:

[0030] 1. By setting up an air guide pipe, the present invention can guide the air blown out by the fan. The strip-shaped waste material enters the collection box from the inlet through the air guide pipe. This can restrict the movement path of the strip-shaped waste material. At the same time, the way the strip-shaped waste material is blown by the wind is relatively gentle, which is not easy to break the strip-shaped waste material. Even if it is broken, it will not affect the next strip-shaped waste material being blown into the collection box. This avoids the situation where the strip-shaped waste material is caught in the cutting device due to its unpredictable nature, and can better collect the cut waste material.

[0031] 2. This invention uses a pull rope and a pull ring. Pulling the pull ring controls the start of the first cylinder. The pull ring is equivalent to a switch that can be controlled by the operator. At the same time, the pull ring can be blown by the wind, which makes it easier for the operator to observe the air outlet more intuitively and judge the collection situation in the inner cavity.

[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail to make the technical solution of this application easier to understand and master.

[0038] This application discloses a nonwoven fabric winding device.

[0039] Reference Figures 1-4 This embodiment of a nonwoven fabric winding device includes a frame 1, on which a cutting device 2, a winding device 3, and a collecting device 4 are provided. The cutting device 2 is used to cut the nonwoven fabric, the winding device 3 is used to wind up the cut nonwoven fabric, and the collecting device 4 is used to collect the waste material after cutting.

[0040] Reference Figures 1-4 The winding device 3 includes a first motor 31, a tension roller 32, and a winding roller 33. Both the tension roller 32 and the winding roller 33 rotate on the frame 1. The first motor 31 is fixed on the frame 1, and its output shaft is coaxially fixed on the winding roller 33, driving the winding roller 33 to rotate. The tension roller 32 is located between the winding roller 33 and the cutting device 2, and is used to increase the tension of the slit nonwoven fabric, thereby facilitating the winding roller 33 to wind it up.

[0041] Reference Figures 1-4 The cutting device 2 includes a cutting roller 21, several cutters 22, and a drive mechanism 23. The cutting roller 21 is mounted on a frame 1. The cutters 22 are circular and are slidably mounted on the frame 1 along the axial direction of the cutting roller 21, with the cutting edge of the cutter 22 facing the cutting roller 21. The drive mechanism 23 is mounted on the frame 1, and the cutters 22 are connected to the drive mechanism 23. The drive mechanism 23 drives the cutters 22 to rotate and moves the cutters 22 towards or away from the cutting roller 21.

[0042] Reference Figures 1-4 The drive mechanism 23 includes several second cylinders 231, several second motors 232, and a slide rail 233. The slide rail 233 is fixedly mounted on the frame 1, located diagonally below the cutting roller 21. The second cylinders 231 are slidably mounted on the slide rail 233, and a positioning bolt is threaded onto each second cylinder 231 to lock its position on the slide rail 233. The second motors 232 are fixedly mounted on the piston rods of the second cylinders 231. The rotating shaft 531 of the cutter 22 is coaxially connected to the drive shaft of the first motor 31, and the second cylinders 231 drive the cutter 22 to move toward or away from the cutting roller 21. A cutting cover 234 for covering the cutter 22 is fixedly mounted on the side wall of the second motor 232.

[0043] Reference Figures 1-4 A number of cutting discs 211 slide along the axis of the cutting roller 21. The cutting discs 211 are fixed to the cutting roller 21 by bolts. A number of cutting grooves matching the cutter 22 are opened on the side wall of the cutting discs 211.

[0044] Reference Figures 1-4 The collecting device 4 includes a fan 41, a guide pipe 42, and a collecting box 43 with an inner cavity 431. A transmission belt 34 is connected to the output shaft of the first motor 31. The transmission belt 34 is wound around the output shaft of the first motor 31 and the input shaft of the fan 41. While the first motor 31 drives the take-up roller 33 to rotate, the output shaft of the first motor 31 drives the input shaft of the fan 41 to rotate through the transmission belt 34, realizing the synchronous operation of the fan 41 and the take-up device 3. This saves power and eliminates the need for operators to separately turn off the fan 41, thus improving work efficiency.

[0045] Reference Figures 1-4 The collection box 43 is fixed on the frame 1, and the first motor 31 and the collection box 43 are located on opposite sides of the take-up roller 33. The collection box 43 has an air inlet 432 and an air outlet 433 that connect to the inner cavity 431. The air inlet 432 is located at the top of the collection box 43, and the air outlet 433 is located on the side wall of the top of the collection box 43. The air guide pipe 42 is fixed on the frame 1. One end of the air guide pipe 42 is connected to the air outlet of the fan 41, and the other end of the air guide pipe 42 is connected to the air inlet 432 of the collection box 43. The air guide pipe 42 passes under the non-woven fabric to be cut. The top wall of the air guide pipe 42 is provided with two feed ports for strip-shaped waste materials to enter the air guide pipe 42. The strip-shaped waste materials enter the collection box 43 from the feed ports, through the air guide pipe 42, and then into the collection box 43.

[0046] Reference Figures 1-4The bottom of the collection box 43 has a discharge port 434, and a pull plate 435 slides horizontally at the discharge port 434 to block it. The discharge port 434 is large enough that the waste in the collection box 43 can completely pass through it. By pulling the pull plate 435, the waste in the collection box 43 can fall automatically, which facilitates the use of the collection device 4.

[0047] Reference Figures 1-4 The air duct 42 guides the air blown out by the fan 41. The strip-shaped waste enters the collection box 43 from the inlet through the air duct 42. This restricts the movement path of the strip-shaped waste. At the same time, the way the strip-shaped waste is blown by the wind is relatively gentle, which makes it less likely to break the strip-shaped waste. Even if it breaks, it will not affect the next strip-shaped waste being blown into the collection box 43. This avoids the situation where the strip-shaped waste is caught in the cutting device 2 due to its uncertainty, and can better collect the cut waste.

[0048] Reference Figures 1-4 The collection box 43 is equipped with a compression device 5, which is used to compress the waste material inside the collection box 43. The compression device 5 includes a first cylinder 51, a pressure plate 52, a flap 53, and a baffle 54. The first cylinder 51 is fixed above the collection box 43, and the piston rod of the first cylinder 51 extends vertically downward into the inner cavity 431 and is fixed on the pressure plate 52, which drives the pressure plate 52 to slide vertically in the inner cavity 431. The pressure plate 52 is used to compress the waste material inside the collection box 43. The pressure plate 52 is located outside the air inlet 432 and does not block the air inlet 432.

[0049] Reference Figures 1-4 The end of the pressure plate 52 near the air outlet 433 abuts against the inner wall of the inner cavity 431. When the piston rod of the first cylinder 51 retracts, the pressure plate 52 moves to abut against the top wall of the inner cavity 431, at which time the pressure plate 52 is located above the air outlet 433.

[0050] Reference Figures 1-4 Because the non-woven fabric waste is collected in a relatively loose state in the collection box 43, after a period of collection, the non-woven fabric will fill the collection box 43, making it difficult for subsequent non-woven fabric waste to enter the collection box 43, thus affecting the continuous collection of the collection box 43; by driving the pressure plate 52 through the first cylinder 51 to compress the non-woven fabric waste already collected in the collection box 43, space can be left for the collection box 43 to continuously collect non-woven fabric waste.

[0051] Reference Figures 1-4A rotating shaft 531 is fixed to one end of the flap 53. The rotating shaft 531 rotates on the pressure plate 52 along the horizontal axis. When the flap 53 rotates to a horizontal position, it is located directly below the air inlet 432. A torsion spring is installed on the rotating shaft 531, which drives the rotating shaft 531 to rotate in the direction where the flap 53 is horizontal. The pressure plate 52 has a mounting groove, which allows the end of the flap 53 to move. When the flap 53 is not subjected to external force, it rotates to abut against the pressure plate 52. At this time, the flap 53 rotates to abut against the top wall of the mounting groove, and the flap 53 is horizontally positioned and directly facing the air inlet 432.

[0052] Reference Figures 1-4 By setting up the flap 53, when the collection box 43 is not in use, the flap 53 can rotate under the action of the torsion spring to block the air inlet 432, which can prevent foreign objects from entering the collection box 43 from the air inlet 432. When the collection box 43 is used to collect non-woven fabric waste, the wind at the air inlet 432 blows directly at the flap 53. The wind force drives the flap 53 to rotate, so that the non-woven fabric waste can enter the lower part of the inner cavity 431 from the gap between the flap 53 and the inner wall of the inner cavity 431. This can prevent the wind from blowing directly on the non-woven fabric in the collection box 43 and prevent the compressed non-woven fabric waste in the collection box 43 from being blown away.

[0053] Reference Figures 1-4 When the pressure plate 52 is pressed down, the flap 53 abuts against the non-woven fabric waste and can press the non-woven fabric waste, which can increase the pressing area of ​​the non-woven fabric waste. At the same time, the wind blowing on the flap 53 can help the flap 53 to press down.

[0054] Reference Figures 1-4 The compression device 5 also includes a baffle 54, which is located above the pressure plate 52. The bottom end of the baffle 54 is vertically fixed to the end of the pressure plate 52 near the flap 53. The baffle 54 slides vertically on the collection box 43, and the top end of the baffle 54 extends out of the collection box 43. The baffle 54 divides the space above the pressure plate 52 and the flap 53 in the inner cavity 431 into two chambers. The baffle 54 is used to prevent waste from entering the chamber directly above the pressure plate 52.

[0055] Reference Figures 1-4 During the pressing process of the pressure plate 52 and the flip plate 53, non-woven fabric waste will continue to enter the inner cavity 431. At this time, the baffle 54 can separate these subsequently entering non-woven fabric wastes and prevent the wastes from entering the cavity directly above the pressure plate 52. In this way, during the resetting process of the pressure plate 52 and the flip plate 53, the wastes accumulated above the flip plate 53 will enter the inner cavity 431 below the flip plate 53 as the flip plate 53 is opened, without affecting the collection of non-woven fabric wastes.

[0056] Reference Figures 1-4A detection element 6 is provided at the air outlet 433. The detection element 6 is used to detect whether the waste collected in the collection box 43 is full. The detection element 6 is a filter screen 61. The filter screen 61 is set at the air outlet 433. When the waste fills the inner cavity 431, the waste located at the top of the inner cavity 431 is adsorbed on the filter screen 61.

[0057] Reference Figures 1-4 The air outlet 433 is also equipped with two first springs 71, two fixing blocks 72, and a control switch 73. Slider blocks 611 are fixed to both ends of the filter screen 61. The sliders 611 slide horizontally within the air outlet 433 from the side closest to the inner cavity 431 to the side furthest from the inner cavity 431, and are flush with the side of the filter screen 61 closest to the inner cavity 431. The two fixing blocks 72 are respectively fixed to the top and bottom walls of the air outlet 433, directly opposite the two sliders 611, and located on the side of the filter screen 61 furthest from the inner cavity 431. The fixing blocks 72 have grooves 721 facing the filter screen 61, and the two first springs 71 correspond to the two grooves 721, with their ends fixed to the bottom wall of the corresponding groove 721 and the corresponding slider 611, respectively. The two control switches 73 are respectively installed on the side of the two fixing blocks 72 facing the filter screen 61.

[0058] Reference Figures 1-4 The control switch 73 is used to control the operation of the first cylinder 51. When the waste fills the inner cavity 431, the waste near the air outlet 433 will be adsorbed onto the filter screen 61, blocking the filter screen 61. The force on the filter screen 61 will increase, and the filter screen 61 will move towards the control switch 73 until the slider 611 abuts against the corresponding control switch 73. When both control switches 73 are pressed, the first cylinder 51 can be driven to run once. At this time, the filter screen 61 is flush with the inner wall of the inner cavity 431 near the air outlet 433.

[0059] Reference Figures 1-4 During the extension of the piston rod of the first cylinder 51, the pressure plate 52 will abut against the filter screen 61 and scrape off the waste material attached to the filter screen 61. At the same time, the debris attached to the filter screen 61 will also be scraped off along with the waste material. Compared with using the pressure plate 52 alone to scrape off the debris, the waste material can be used to clean the mesh of the filter screen 61 better, thus improving the cleaning effect of the filter screen 61.

[0060] Reference Figures 1-4 The pressure plate 52 has chamfers 521 on its upper and lower edges near the filter screen 61. The chamfers 521 are used to abut against the slider 611 that extends into the inner cavity 431. During the sliding process, the pressure plate 52 can actively drive the slider 611 and the filter screen 61 to move towards the air outlet 433 without being disturbed by the slider 611 and the filter screen 61 in the inner cavity 431.

[0061] Reference Figures 1-4 When the pressure plate 52 is reset, it will pass through the filter screen 61 again. At this time, it will drive the slider 611 to abut against the control switch 73. During the operation of the first cylinder 51, pressing the control switch 73 will not drive the first cylinder 51 to run again. Only when the waste fills the inner cavity 431 again can the first cylinder 51 be driven to run again.

[0062] Reference Figures 1-4 A pull cord 74 is provided on the filter screen 61. One end of the pull cord 74 is fixed to the filter screen 61, and the other end of the pull cord 74, away from the filter screen 61, extends out of the air outlet 433 and is fixed with a pull ring 75. The pull ring 75 is made of lightweight materials such as plastic or cloth, and can be blown by the air blown out of the air outlet 433. The operator can control the first cylinder 51 to start by pulling the pull ring 75. The pull ring 75 is equivalent to a switch that can be controlled by the operator. At the same time, the pull ring 75 can be blown by the wind, which makes it easier for the operator to observe the air outlet 433 more intuitively to judge the collection situation in the inner cavity 431.

[0063] Reference Figures 1-4 Below the collection box 43 is a receiving box 44, which is used to receive the compressed non-woven fabric inside the collection box 43. The bottom of the receiving box 44 is also equipped with multiple rollers, which makes it easier for operators to push the receiving box 44 to move.

[0064] Of course, the above are just typical examples of this application. In addition, this application may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed in this application.
