[0016] To describe the technical content, structural features, achieved purpose and effect of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0017] An embodiment of the present application provides a production equipment for continuous welding and slitting of needle-punched cotton. Multiple layers of needle-punched cotton are stacked into a multi-layer product in the production equipment and conveyed from front to back. The production equipment continuously welds and longitudinally and transversely slitting the multi-layer product according to production requirements, so that the multi-layer product is divided into multiple multi-layer products that meet the production requirements.

[0018] like Figure 1 As shown, the production equipment includes: a frame 1 and an unwinding mechanism 2, a longitudinal cutting knife device 3, a welding mechanism 4, a transverse cutting knife device 5, a belt conveying mechanism 6 and a pressing mechanism 7 installed on the frame 1. The unwinding mechanism 2, the longitudinal cutting knife device 3, the welding mechanism 4, the transverse cutting knife device 5 and the belt conveying mechanism 6 are arranged in sequence from front to back, and the pressing mechanism 7 is installed on the belt conveying mechanism 6.

[0019] like Figure 1 , 2 As shown, the unwinding mechanism 2 includes a plurality of unwinding stations 21, each of which is provided with an inflatable shaft 22 that can rotate around its own axis, and each of which is used to unwind the needle-punched cotton toward the rear side.

[0020] The unwinding mechanism 2 also includes an unwinding motor 23 and a tension controller 24. Each air shaft 22 is connected to an unwinding motor 23 in a transmission manner. The unwinding motor 23 is used to drive the corresponding air shaft 22 to rotate around its own axis, so that the needle-punched cotton is released when the air shaft 22 rotates. The unwinding motor 23 is connected to the tension controller 24 by signal. The tension controller 24 controls the unwinding motor 23 so that the air shaft 22 unwinds the needle-punched cotton with constant tension, thereby preventing the needle-punched cotton from being stretched or releasing the needle-punched cotton too quickly to cause the needle-punched cotton to sag.

[0021] A transition mechanism 8 is provided between the unwinding mechanism 2 and the longitudinal cutting device 3, and the transition mechanism 8 includes a plurality of transition rollers 81 arranged at intervals from front to back. The plurality of transition rollers 81 are arranged alternately up and down, and each transition roller 81 extends in the left-right direction and can rotate around its own axis, and the multilayer product passes around the plurality of transition rollers 81 in a serpentine shape from front to back. A detection device 82 is also installed on the transition mechanism 8, and the detection device 82 includes a detection switch 821 and a reflector 822. The detection switch 821 and the reflector 822 are respectively installed on the left and right sides of multiple transition rollers 81. The detection switch 821 is connected to the tension controller 24 signal. The detection switch 821 can emit light toward the reflector 822, and the reflector 822 reflects the light back to the detection switch 821. The detection switch 821 detects whether the reflected light is received and transmits the detection result to the tension controller. When the multi-layer product is conveyed normally, the light emitted by the detection switch 821 will be blocked. When the multi-layer product sags, the emitted light will be projected onto the reflector and reflected by the reflector to the detection switch 821. The detection switch 821 detects the light and transmits a signal to the tension controller 24. The tension controller 24 controls the unwinding motor to reduce the speed or stop rotating.

[0022] The longitudinal cutting knife device 3 has a longitudinal cutting knife 31 which can cut the multi-layer product along the front-to-back direction. The longitudinal cutting knife device 3 includes a pair of longitudinal cutting knives 31. The pair of longitudinal cutting knives 31 are arranged opposite to each other on the left and right, and each longitudinal cutting knife 31 is configured to be able to move in the left and right direction, so that the position of the pair of longitudinal cutting knives 31 in the left and right direction can be adjusted according to production requirements, and finally the width of the product that meets the production requirements can be cut out.

[0023] The welding mechanism 4 is arranged at the rear side of the longitudinal cutting device, and is used to weld the stacked needle-punched cotton together, so as to facilitate subsequent processing into products such as masks, protective clothing, and surgical gowns. In the embodiment of the present application, the welding mechanism 4 is an ultrasonic welding machine, which increases the temperature of the contact position by over-frequency vibration on the surface of the multi-layer product, so that the needle-punched cotton in this part melts quickly and the stacked parts adhere to each other, and are shaped under the pressure of movement, thereby achieving the purpose of welding the stacked needle-punched cotton.

[0024] The transverse cutting device 5 is installed at the rear side of the welding mechanism 4. The transverse cutting device 5 has a transverse cutting knife 51 that can move back and forth in the left and right directions. The transverse cutting knife 51 cuts the multi-layer product horizontally from left to right or from right to left. The transverse cutting device 5 and the longitudinal cutting device 3 cut the stacked needle-punched cotton into a plurality of multi-layer products that meet the production requirements.

[0025] A traction device 9 is provided between the welding mechanism 4 and the transverse cutting device 5, and the traction device 9 provides power for conveying the multilayer product in the production equipment, thereby pulling the multilayer product from the welding mechanism 4 to the transverse cutting device 5. The traction device 9 includes upper and lower opposite traction rollers 91, the upper traction roller 91 presses the multilayer product against the lower traction roller 91, and the upper and lower traction rollers 91 rotate synchronously to pull the multilayer product backward to avoid friction pulling the multilayer product.

[0026] The belt conveyor mechanism 6 is arranged at the rear side of the transverse cutting device 5. The belt conveyor mechanism 6 includes a pair of conveyor rollers 61 arranged opposite to each other in front and back, a conveyor motor (not shown in the figure) drivingly connected to one of the conveyor rollers 61, and a conveyor belt 62 stretched on the pair of conveyor rollers 61. The conveyor belt 62 rotates under the drive of the pair of conveyor rollers 61 to convey the multi-layer product from front to back.

[0027] The pressing mechanism 7 is installed on the belt conveyor 6, and includes a pressing component (not shown in the figure) that can move downward to press the multi-layer product on the belt conveyor 6 and a pressing cylinder 71 that drives the pressing component to press the multi-layer product. When the transverse cutter device 5 cuts the multi-layer product, the conveying roller 61 of the belt conveyor 6 stops rotating, and the traction roller 91 of the traction device 9 stops rotating; the upper traction roller 91 presses the multi-layer product on the lower traction roller 91 to fix the multi-layer product on the front side of the transverse cutter 51, and the pressing mechanism 7 presses the multi-layer product on the belt conveyor 6 to fix the multi-layer product on the rear side of the transverse cutter 51; the fixed multi-layer product is easy to be cut horizontally by the transverse cutter device 5, which effectively avoids cutting crookedly and improves the neatness of the product edge and the beauty of the product.

[0028] In the embodiment of the present application, the unwinding mechanism 2 has two unwinding stations 21 . When the production equipment is working, the two air shafts 22 of the unwinding mechanism 2 release the needle-punched cotton backwards with constant tension respectively, and the double-layer needle-punched cotton is stacked up and down on the transition mechanism 8 and transported backwards under the traction of the traction device 9; a pair of longitudinal cutters 31 of the longitudinal cutter device 3 moves to the required position, and the rotating longitudinal cutters 31 cut the stacked double-layer needle-punched cotton; the welding mechanism 4 welds the longitudinally cut double-layer needle-punched cotton, and the welded double-layer needle-punched cotton is pulled backwards by the traction device 9 to the transverse cutter device 5, and the transverse cutter device 5 performs transverse cutting of the double-layer needle-punched cotton according to production requirements. When the transverse cutter device 5 performs transverse cutting, the traction device 9 presses the double-layer needle-punched cotton, and the pressing mechanism 7 presses the double-layer needle-punched cotton on the belt conveyor mechanism 6 that stops conveying, and the transverse cutter 51 cuts the double-layer needle-punched cotton transversely, and the pressing component of the pressing mechanism is lifted, and the traction device 9 continues to pull, and the conveying belt 62 of the belt conveyor mechanism 6 rotates to transport the transversely cut double-layer needle-punched cotton to the rear side to the stacking station.

[0029] The present application can cut multiple layers of needle-punched cotton longitudinally and transversely, and continuously weld multiple layers of needle-punched cotton, so that the multiple layers of needle-punched cotton are cut into multiple independent products that are convenient for subsequent processes. It has a simple structure, convenient operation, and a high degree of automation.
