Description

Technical Field

[0001] The utility model relates to the technical field of material processing, and particularly relates to a slitting and winding device for high-voltage electrostatic spinning filter materials. Background Art

[0002] The high-voltage electrostatic spinning technology is a method for preparing nano- and micro-fiber materials by using the breakdown effect of a high-voltage electrostatic field on polymer solutions, and can also be used for processing and producing nano air filter materials. In the actual processing and production process, after the filter material composite is sprayed with glue and cured, due to the large overall area of the filter material composite, the filter material composite is generally slit first and then wound into a coil to meet the production requirements of various filter material widths.

[0003] In the prior art, the cutting and winding of the filter material composite are generally carried out by separately arranged slitting equipment and winding equipment. Specifically, the filter material composite is first transported to the slitting equipment for cutting to the required width, and then the cut filter material composite is transported to the winding equipment for winding.

[0004] However, in actual application, the cost of purchasing two types of equipment is relatively high, the floor area is large, and the applicability is not high. Moreover, due to the relatively soft material of the filter material, the filter material is prone to slack during the long-distance transportation between multiple equipment such as the glue spraying equipment, slitting equipment, and winding equipment, resulting in uneven slitting, poor slitting effect, and uneven winding of the filter material. Content of the Utility Model

[0027] Please refer to Figures 1 to 2 , the high-voltage electrostatic spinning filter material cutting and winding device of the present utility model includes a mounting frame 10, a traction assembly 20 connected to the mounting frame 10, a winding assembly 30 disposed between two side plates 11 of the mounting frame 10, and a cutting assembly 40 disposed on the side of the winding assembly 30 close to the traction assembly 20.

[0028] As an example, the traction assembly 20 is used to guide the filter material to be transmitted to the cutting assembly 40 for the cutting process.

Further, the traction assembly 20 further includes two first support plates 21 and two second support plates 23. The first traction roller 22 is disposed between the two first support plates 21. One end of the first support plate 21 is fixedly connected to the top plate of the side plate 11, and the other end of the first support plate 21 is rotatably connected to the end of the first traction roller 22.

One end of the second support plate 23 is fixedly provided on the top of the side plate 11, and the other end of the second support plate 23 is rotatably connected to the end of the second traction roller 24.

[0029] For illustrative purposes, the rewinding assembly 30 is used to wind the slit filter material. Specifically, in this embodiment, the rewinding assembly 30 includes an auxiliary roller 32 and a winding roller 31 arranged in parallel. The auxiliary roller is used to guide the slit filter material to the winding roller 31 for the winding process, so as to achieve the purpose of double-roller winding, improve the winding flatness of the filter material, and at the same time can also wind hard materials such as PET, improving the applicability of the device. The auxiliary roller 32 is arranged adjacent to the second traction roller 24, and the top outer edges of both the auxiliary roller 32 and the winding roller 31 are lower than the bottom outer edge of the second traction roller 24. The roller diameters of the auxiliary roller 32 and the winding roller 31 are the same, and the centers of the auxiliary roller 32 and the winding roller 31 are located on the same horizontal plane. The two ends of the auxiliary roller 32 and the winding roller 31 are respectively rotatably connected to the two side plates 11 of the mounting frame 10. After the filter material is slit through the gap between the slitting knife 42 and the auxiliary roller 32, it successively bypasses the bottom outer edge of the auxiliary roller 32 and the top outer edge of the winding roller 31, and is wound by the winding roller 31. Further, the rewinding assembly 30 further includes two cylinders 33, and the cylinders 33 are used to control the tightness of the winding roller 31 to ensure the winding quality of the filter material. Specifically, in this embodiment, the two cylinders 33 are respectively arranged on two opposite sides of the mounting frame 10 and above the winding roller 31, and the two ends of the winding roller 31 are respectively rotatably connected to the bottom ends of the cylinders 33.

[0030] The slitting assembly 40 is used to slit the filter material. Specifically, in this embodiment, the slitting assembly 40 includes a mounting plate 41 fixedly connected to the two side plates 11 and a plurality of slitting knives 42 arranged on the mounting plate 41 at intervals along the axial direction of the auxiliary roller 32. The slitting knives 42 are located below the side of the auxiliary roller 32 away from the winding roller 31, and there is a gap for the filter material to pass through between the slitting knives 42 and the auxiliary roller 32. Further, a slide bar 411 is provided on the mounting plate 41, and a sliding groove 421 is provided at the bottom of the slitting knife 42. The sliding groove 421 is adapted to the slide bar 411, and the slitting knife 42 can slide on the mounting plate 41. In this way, the distance between the two slitting knives 42 can be adjusted according to actual needs, thereby achieving the purpose of slitting the filter material into different widths and improving the applicability. To fix the position of the slitting knife 42 on the mounting plate 41, a limit pin 422 is provided at the bottom of the slitting knife 42 in this embodiment. In the width direction of the notch of the sliding groove 421, a limit hole for the limit pin 422 to pass through is provided at the bottom of one side of the slitting knife 42, and the limit hole is communicated with the sliding groove 421. The end of the limit pin 422 can pass through the limit hole and enter the sliding groove 421, so that when the slitting knife 42 is located at a predetermined mounting position, the limit pin 422 can be tightened and the limit pin 422 can be tightly abutted against the side wall of the slide bar 411, thereby restricting the sliding of the slitting knife 42 on the slide bar 411 and achieving the purpose of fixing the position of the slitting knife 42. Further, the slitting knife 42 is a pneumatic top knife.

[0031] Further, the high-voltage electrostatic spinning filter material slitting and winding device further includes a pressing roller 50, which is located between the second traction roller 24 and the auxiliary roller 32. The pressing roller 50 is arranged above the slitting knife 42. The two ends of the pressing roller 50 are respectively rotatably connected to the two side plates 11. The outer edge of the top of the pressing roller 50 is higher than the outer edge of the top of the auxiliary roller 32 and lower than the outer edge of the top of the second traction roller 24. The setting of the pressing roller 50 can ensure the uniform state of the tension of the filter material during the process of being transmitted from the second traction roller 24 to the position of the slitting knife 42, so that the filter material can be transmitted to the slitting knife 42 smoothly and evenly for slitting, thereby improving the slitting effect of the filter material.

[0032] During the actual use process, the working principle of the high-voltage electrostatic spinning filter material slitting and winding device of the present invention can be as follows: The tightness of the winding of the filter material by the winding roller 31 is adjusted through the air cylinder 33, and the linear speed of the winding roller 31 and the linear speed of the second traction roller 24 are slightly greater than the linear speed of the first traction roller 22, so that the filter material can be tightened during the transmission process, thereby effectively preventing the filter material from becoming loose. The filter material first is transmitted obliquely downward from the outer edge of the top of the first traction roller 22 to the top of the second traction roller 24, and then is transmitted obliquely downward from the outer edge of the top of the second traction roller 24 to the pressing roller 50. Subsequently, it passes through the gap between the slitting knife 42 and the auxiliary roller 32. During this process, the slitting knife 42 slits the filter material. The slit filter material bypasses the outer edge of the bottom of the auxiliary roller 32 and is transmitted obliquely upward to the outer edge of the top of the winding roller 31, and finally is wound by the winding roller 31.

[0033] In summary, the beneficial effects of the high-voltage electrostatic spinning filter material slitting and winding device of the present invention are as follows: The structure is compact, with a slitting component and a winding component integrated, which reduces the production cost, reduces the floor area, has high applicability, and the slitting knife in the slitting component is arranged adjacent to the auxiliary roller in the winding component. The filter material is slit in the gap between the slitting knife and the auxiliary roller, which avoids the long-distance transmission process of the filter material in multiple devices. Further, during the actual operation process, the filter material can be tightened through the coordinated operation of the traction component and the winding component. Specifically, by making the linear speeds of the winding roller and the second traction roller greater than the linear speed of the first traction roller, the overall tightening of the filter material can be achieved, thereby effectively avoiding the situation of the filter material becoming loose during the transmission process and ensuring the uniformity during the slitting process of the filter material and the flatness of winding.
