[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] Please refer to Figures 1 to 3 , the traction device for high-voltage electrostatic spinning filter media spray gluing composite of the present utility model includes an installation frame 1, exhaust hoods 2 and a traction assembly respectively arranged at both ends of the top of the installation frame 1, and a pressing assembly arranged at the top of the installation frame 1 and located between the exhaust hood 2 and the traction assembly. The installation frame 1 below the exhaust hood 2 is used to install a spray gluing composite device (not shown in the figure), and the spray gluing composite device is used to spray glue on the substrate. The control system of the spray gluing composite device is signal-connected to the control system of the traction device so that the glue spraying amount of the spray gluing composite device matches the traveling speed of the substrate in the traction device. It should be noted that in some embodiments, the distance between the glue spraying head in the spray gluing composite device installed on the installation frame 1 and the substrate can be adjusted, which can better improve the glue spraying uniformity.

[0027] As an example, the pressing assembly is arranged adjacent to the exhaust hood 2. The pressing assembly includes first mounting plates 31 respectively fixedly provided on both sides of the installation frame 1 and a pressing roller 32 arranged between the two first mounting plates 31. The pressing roller 32 can perform a pressing operation on the composite material after spray gluing to improve the composite stability of the composite material.

[0028] As an example, the exhaust hood 2 is used to collect and discharge the sprayed glue flocs and hot air generated during the glue spraying process of the glue spraying composite equipment. Specifically, the exhaust hood 2 includes an air inlet part 21, a hood part 22, and an exhaust part 23 that are connected in sequence from bottom to top. An air inlet 201 is provided at one end of the air inlet part 21 away from the hood part 22. The air inlet 201 is arranged close to the top of the pressing roller 32, and the diameter of the air inlet 201 gradually decreases in the direction of the exhaust part 23. As a specific example, in this embodiment, the cross-section of the air inlet 201 is a regular trapezoidal structure, so as to guide the sprayed glue flocs and hot air to move from both sides of the air inlet 201 to the upper part of the middle of the air inlet 201 and finally be discharged from the exhaust part 23.

[0029] Furthermore, a first side plate 24 is provided on one side of the air inlet part 21 close to the pressing roller 32, and a second side plate 25 is provided on the side of the air inlet part 21 opposite to the first side plate 24. In the height direction of the exhaust hood 2, the lower edge of the second side plate 25 is lower than the lower edge of the first side plate 24. The lower edge of the first side plate 24 is higher than the bottom outer edge of the pressing roller 32 and lower than the top outer edge of the pressing roller 32. In the actual application process, the lower edge of the first side plate 24, the lower edge of the second side plate 25, and the top outer edge of the pressing roller 32 are guiding surfaces. The connection line among the lower edge of the second side plate 25, the lower edge of the first side plate 24, and the top outer edge of the pressing roller 32 is designed to be inclined, which can meet the upward trend of the base material. After the base material is sprayed and compounded, it bypasses from the top outer edge of the pressing roller 32 and finally passes through the gap between the first traction roller 42 and the second traction roller 43.

[0030] Furthermore, the design of the hood part 22 is used to increase the height of the exhaust part 23. One end of the hood part 22 is connected to the top end of the air inlet part 21, and the other end of the hood part 22 is connected to the bottom end of the exhaust part 23. An exhaust fan can be arranged in the hood part 22. A discharge port 202 is provided in the middle of the top end of the exhaust part 23, and the discharge port 202 is higher than the pressing assembly. As a specific example, in this embodiment, the cross-section of the exhaust part 23 is an inverted trapezoidal structure, and the discharge port 202 is a circular through hole. In actual use, the discharge port 202 is connected to an external exhaust duct. The sprayed glue flocs and hot air generated during the glue spraying process of the glue spraying composite equipment located below the exhaust hood 2 are inhaled from the air inlet 201 of the air inlet part 21 and finally discharged from the discharge port 202 of the exhaust part 23, thereby effectively dealing with the problem of hot melt glue flocs during the glue spraying and compounding process.

[0031] As an example, the traction assembly is used to traction and convey composite materials. The traction assembly includes second mounting plates 41 respectively fixed on both sides of the mounting frame 1, and a first traction roller 42 and a second traction roller 43 arranged in parallel between the two second mounting plates 41. The first traction roller 42 is located directly above the second traction roller 43, and a gap for the composite material to pass through is provided between the first traction roller 42 and the second traction roller 43. Further, the top outer edge of the first traction roller 42 is lower than the top outer edge of the pressing roller 32. In actual use, the composite material bypasses the top outer edge of the pressing roller 32 and then passes through the gap between the first traction roller 42 and the second traction roller 43 obliquely downward.

[0032] The traction device for high-voltage electrostatic spinning filter media spray bonding and compounding of the present utility model further includes an arc roller 51. The arc roller 51 is used to unfold the material to eliminate wrinkles during the movement of the composite material and ensure the flatness of the material. As a specific example, in this embodiment, the arc roller 51 is located between the pressing assembly and the traction assembly and is obliquely below the second traction roller 43. Both ends of the arc roller 51 are respectively connected to the mounting frame 1 through connecting plates 52.

[0033] Further, the traction device for high-voltage electrostatic spinning filter media spray bonding and compounding of the present utility model further includes an unwinding assembly. The unwinding assembly is located below the traction assembly. The unwinding assembly includes third mounting plates 61 respectively fixed on both sides of the bottom of the mounting frame 1 and an unwinding roller 62 placed above the two third mounting plates 61. The unwinding roller 62 can be used to place substrates such as meltblown or other raw materials. A placement hole 601 for placing the unwinding roller 62 is provided on one side of the third mounting plate 61 close to the traction assembly. As a specific example, in this embodiment, the placement hole 601 is an inclined U-shaped hole, and the opening of the U-shaped hole faces the top of the mounting frame 1. Further, the unwinding roller 62 includes a roller body portion and a rotating shaft portion passing through the roller body portion. The roller body portion is used to place the substrate, and both ends of the rotating shaft portion are respectively placed in the placement hole 601. A plurality of protruding blocks 621 are provided on the circumferential side surface of the roller body portion, and the protruding blocks 621 are used to reinforce the placement of the substrate on the roller body portion.

[0034] During actual use, the working principle of the traction device for high-voltage electrostatic spinning filter media spray-bonding composite of the present utility model can be as follows: A spray-bonding composite device is installed below the exhaust hood 2. The substrate after being spray-bonded by the spray-bonding composite device sequentially passes through the second side plate 25 and the first side plate 24 below the exhaust hood 2, and bypasses the top outer edge of the pressing roller 32 and obliquely descends through the gap between the first traction roller 42 and the second traction roller 43. The cooperation of the first traction roller 42, the second traction roller 43 and the pressing roller 32 enables the spray-bonded composite material to be smoothly and stably conveyed to the next stage. Further, since the control system of the entire traction device is signal-connected to the control system of the spray-bonding composite device, the spray-bonding composite device can automatically adjust the spray volume according to the traveling speed signal of the material, thereby ensuring the uniformity of the spraying of the spray-bonding composite device during the material traveling process. The spray-bonding flocs and hot air generated during the spraying of the substrate by the spray-bonding composite device will be sucked by the exhaust hood 2 and discharged into the external exhaust duct.

[0035] In summary, the beneficial effects of the traction device for high-voltage electrostatic spinning filter media spray-bonding composite of the present utility model are as follows: It has a compact structure, is convenient for handling and installation. By integrally arranging an exhaust hood, a pressing assembly and a traction assembly on the installation frame, the pressing and stable traction of the composite material obtained after spray-bonding the substrate are realized, which can effectively ensure the flatness of the composite material, and the exhaust hood effectively collects and treats the spray-bonding flocs during the spray-bonding process of the substrate, avoiding harm to the health of the operator. Specifically, the installation frame below the exhaust hood is used to install the spray-bonding composite device. The substrate undergoes spray-bonding composite operation in the spray-bonding composite device below the exhaust hood. During this process, since the control system of the entire traction device is signal-connected to the control system of the spray-bonding composite device, the spray-bonding composite device can automatically adjust the spray volume according to the traveling speed signal of the substrate in the traction device, thereby ensuring the uniformity of the spraying of the spray-bonding composite device during the substrate traveling process. After the substrate is spray-bonded and composite, the composite material passes below the exhaust hood and bypasses the top outer edge of the pressing roller, and obliquely descends and smoothly passes through the gap between the first traction roller and the second traction roller to be transmitted to the next stage.
