Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric mechanical processing, in particular to a melt-blown non-woven fabric processing device. Background Art

[0002] Meltblown nonwoven fabric is a nonwoven paper product first developed by foreign countries in recent years. It consists of two layers of microwave-rich porous nonwoven fiber cloth layers and a fiber layer containing hot-melt adhesive fibers that is located between the nonwoven fiber cloth layers and adhered to the nonwoven paper fiber cloth layers. In terms of structure, it is in the form of a sandwich. Its processing equipment includes a nonwoven fabric unwinding mechanism for unwinding nonwoven fiber fabric; a molten fiber extrusion mechanism parallel to the nonwoven fabric unwinding mechanism for generating hot-melt fiber fabric; and a composite molding mechanism for entanglement of nonwoven fiber fabric and hot-melt fiber fabric to form a finished meltblown nonwoven fabric.

[0003] In the prior art, a meltblown nonwoven fabric processing device is proposed in the Chinese patent document meltblown nonwoven fabric processing device with publication number CN207669937U, which includes: a nonwoven fabric unwinding mechanism, a molten fiber extrusion mechanism, a composite molding mechanism and a roller lifting device. The nonwoven fabric unwinding mechanism is used to output the nonwoven fiber fabric; then the molten fiber extrusion mechanism is arranged in parallel on one side of the nonwoven fabric unwinding mechanism, and is used to output the hot molten fiber fabric; the composite molding mechanism is arranged at the output end of the nonwoven fabric unwinding mechanism and the molten fiber extrusion mechanism, receives the nonwoven fiber fabric output by the nonwoven fabric unwinding mechanism and the hot molten fiber fabric output by the molten fiber extrusion mechanism, and combines the two to form a meltblown nonwoven fabric finished product; the roller lifting device is installed on the nonwoven fabric unwinding mechanism, and is used to lift the roller to move / reset. The utility model can mechanically lift the roller with the material roll added to it to the installation position, thereby improving work efficiency and avoiding muscle strain of workers.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0025] like Figures 1 to 5 As shown, a meltblown nonwoven fabric processing device comprises: a conveyor belt 1, a support rod 3, a telescopic rod 9 and a spring 14, a frame 2 is provided at the bottom of the support rod 3, the support rod 3 and the telescopic rod 9 are both arranged on the top of the frame 2, an active rod 4 is rotatably provided inside the support rod 3, and driven rods 5 are rotatably provided at both ends of the active rod 4, an auxiliary rod 20 is provided at the end of the driven rod 5 away from the active rod 4, and side plates 6 are provided at both ends of the auxiliary rod 20, and a central axis 7 is provided in the middle of the side plate 6, a rolling roller 19 is provided on the side of the side plate 6 away from the driven rod 5, and a first driven wheel 13 is provided on the side of the rolling roller 19 that passes through the side plate 6, and a spring 14 is provided inside the side plate 6, and the arrangement of the support rod 3 and the telescopic rod 9 enables the device to be It remains stable during operation and effectively avoids quality problems caused by unstable work. The design of the telescopic rod 9 is to enable the device to better perform intermittent replacement to scrape off foreign matter accumulated on the surface, etc., to ensure the stability of the device. The setting of the spring 14 is so that when one side is lifted during use, the elastic space given to the rolling roller 19 by the spring 14 can prevent the two rolling rollers 19 from leaving the non-woven fabric surface at the same time, thereby improving the practical value of the device. During use, routine work is first performed. When raw material flying catkins accumulate on the rolling roller 19, the telescopic rod 9 can be started to lift the active rod 4 on one side, and the driven rod 5 on the other side drives the corresponding rolling roller 19 to fall, and the rolling work is performed alternately.

[0026] Further, such as Figure 3As shown, a roller brush 16 is provided at the bottom of the frame 2, and the roller brush 16 passes through the frame 2 and is provided with a second driven wheel 15 on the outside. A motor 8 is provided above the frame 2, and a collecting device 18 is provided above the frame 2 at a position corresponding to the roller brush 16. A first driving wheel 11 is provided on one side of the transmission shaft of the motor 8, and a second driving wheel 12 is provided on one side of the first driving wheel 11. This design is to design fewer power sources to achieve the best driving effect, improve the practical value of the device, and save resources. The roller brush 16 is designed to directly cooperate with the collecting device 18 to collect the cleaned flying catkins, so as to avoid secondary environmental pollution and improve the practicality of the device. During use, when the rolling roller 19 on one side is lifted, when the height reaches the highest, the surface of the rolling roller 19 contacts with the roller brush 16, thereby scraping off the surface flying catkins, etc. After cleaning, it can be directly collected and processed by the collecting device 18.

[0027] Further, such as Figure 1 As shown, a third driven wheel 17 is arranged on one side of the central axis 7 that passes through the frame 2, and a bracket 10 is arranged at the bottom of the conveyor belt 1. This design is to better transmit the power transmitted by the power source, and can use energy more economically and reasonably, thereby improving the practical value of the device and reducing resource consumption during use.

[0028] Further, such as Figure 1 As shown, a chain (not shown in the figure) is provided between the first driving wheel 11 and the third driven wheel 17, the second driving wheel 12 and the second driven wheel 15 are connected by a chain, and the third driven wheel 17 and the first driven wheel 13 are connected by a chain. The transmission of kinetic energy through the chain can be more stable and safe, avoiding energy loss in the process of kinetic energy transmission. During use, when the motor 8 transmits kinetic energy, the first driving wheel 11 will pass on the kinetic energy, so that the entire device enters an operating state with less waste of resources.

[0029] Further, such as Figure 4 As shown, a groove is provided at the relative position of the side plate 6 close to the rolling roller 19, one side of the spring 14 is connected to the inner wall of the side plate 6, and the other side is connected to the rolling roller 19. This design can ensure that the two rolling rollers 19 are not in a raised state at the same time, thereby avoiding affecting the normal operation. During use, when the rolling roller 19 on one side is lifted, the rolling roller 19 will fall for a period of time under the influence of the spring 14, thereby ensuring that the other rolling roller 19 is lifted up and leaves the production line only when it falls on the non-woven fabric production line.

[0030] Further, such as Figure 1As shown, the collecting device 18 is a wind collecting component, which needs to be used in conjunction with a fan. A suction port is provided at the lower position thereof, and the suction port is provided at a relative position to the roller brush 16. Such a design can ensure the collection efficiency. A large number of fan devices will be used in the production process of non-woven fabrics. During use, only a portion of the wind power needs to be evenly distributed, thereby improving the practicability of the device.

[0031] Further, such as Figure 3 As shown, the roller brush 16 is a hard roller brush, which is located in the middle of the height of the two rolling rollers 19, and the bristles are in contact with the surfaces of the two rolling rollers 19. This design allows the roller brush 16 to better clean the two rolling rollers 19, thereby ensuring the stable operation of the device. During use, the roller brush 16 body does not need to change its position, and the two rolling rollers 19 will be lifted alternately to perform cleaning work.
