Problems solved by technology

Most of the domestic spinning equipment only measures and controls the ambient temperature of spinning, and occasionally performs simple manual intervention on the humidity, such as adding desiccant, dehumidifier, etc., based on this method to spray electrospun fibers Simple and arbitrary control of ambient temperature and humidity lacks operational reliability and stability of environmental parameters, which is extremely unfavorable for high-quality production or research of electrospun fibers
A small number of high-end electrospinning fiber equipment in foreign countries has installed special temperature and humidity control devices in the spray environment, but the equipment structure is complex and expensive, which is not conducive to large-scale promotion and use in China

Embodiment 1

[0015] Embodiment 1: In order to solve the convenient, accurate, reliable and low-cost control of the temperature and humidity of the electrospun fiber jetting environment, this embodiment provides a combined electrospun fiber jetting environment control device based on a controllable air flow. The device consists of a constant temperature Composed of constant humidity air source, bracket, blowing slot, suction slot, filter screen, and suction fan.

[0016] Wherein: the constant temperature and constant humidity air source can output air with adjustable temperature and humidity, and the air flow is controllable. The constant temperature and constant humidity air source is a common device in the field of automatic control.

[0017] The blowing grooves are connected to the four blowing grooves by the above-mentioned constant temperature and humidity air source, the blowing grooves control the air flow to blow downward at a certain angle, and the four blowing grooves are installed...

Embodiment 2

[0024] Embodiment 2: A combined electrospun fiber injection environment control device based on controllable airflow, including a blowing groove and a suction groove, the described blowing groove is a closed and hollow support frame, and the blowing groove is The hollow layer is connected to the constant temperature and humidity blower to enter the hollow layer of the blowing groove, and the side wall of the support frame is used as a guiding device for air intake to form an air curtain. The described blowing groove is correspondingly provided with a suction groove, and the suction groove It is an enclosed and hollow support frame, in which the hollow layer is connected to the suction fan, and the air curtain formed by the blowing groove is discharged by the suction fan through the suction groove. From the above, an air curtain for the air flow between the blowing groove and the suction groove is formed, so that the spray environment is formed to form a closed space, and the ai...

Embodiment 3

[0040] Embodiment 3: A kind of combined electrospun fiber injection environment control device based on controllable air flow, as an independent embodiment or as the embodiment of the scheme in embodiment 2, the described blowing slot is supported by four rectangles It consists of four rectangular support frames through the connection of the left and right side walls to form an integrated or separate connection. The upper side wall of each rectangular support frame communicates with the blowing groove, and the inner side wall and the outer side wall It is a closed wall, but at least one inner wall of the four rectangular support frames has a horizontal blowing opening, and the lower side wall has a blowing opening, and the air curtain is sent out from the blowing opening, wherein a rectangular support of the blowing slot The inner wall of the sidewall has a horizontal air outlet.

[0041] In one solution, the lower position of the inner wall of the rectangular support frame op...

Abstract

The invention relates to a visual electrospun fiber environment maintaining device and a visible maintaining method for an air curtain, and belongs to the technical field of electrostatic spinning. Inorder to solve the problems about temperature and humidity constant control over electrostatic spinning and make a spinning space compact and adjustable, the device is technically characterized in that an air blowing port of an air blowing groove forms an airflow-controllable section, and a relatively closed rectangular space is formed in an electrospun fiber jetting environment by the section and a collection plate at the bottom. The device has the advantage of making the spinning space compact and adjustable.
