Description

Technical Field

[0001] This utility model relates to the field of meltblown nonwoven fabric production technology, specifically to an automated integrated electrostatic electret device for meltblown nonwoven fabric. Background Technology

[0002] Meltblown nonwoven fabric is widely used as a filter material, medical and health material, environmental protection material, and clothing material. When meltblown fabric is used as a filter material and medical and health material, the requirements for its filtration performance are very high. The filtration performance of meltblown nonwoven fabric itself is only below 70%. To improve its filtration performance, the common method is to add electrostatic charge effect to the meltblown fabric through electrostatic electret process. By using electrostatic methods to improve filtration efficiency, it can reach 99.9%.

[0003] As per application number 202222067630.3, this utility model discloses an electrostatic electret device for meltblown nonwoven fabric, including a box and a meltblown nonwoven fabric body. A hot air blower, a vacuum cleaner and an electrostatic generator are sequentially installed on one outer wall of the box via bolts. The bottom of the adjacent inner walls of the box are movably connected by a rotating shaft to lower guide rollers that are distributed at equal intervals. The top center of the adjacent inner walls of the box is movably connected by a rotating shaft to upper guide rollers on both sides. The meltblown nonwoven fabric body is wrapped around the outside of the lower guide rollers and the upper guide rollers in an M-shape.

[0004] During the processing of meltblown nonwoven fabric, the internal airflow of the device is easily exchanged with the external airflow, which causes dust on the outside to be attracted to the inside. It also easily causes internal heat to escape, resulting in the meltblown nonwoven fabric not meeting the required fluffiness. This leads to low electrostatic treatment efficiency. Furthermore, the side electrostatic treatment method has a small contact area with the nonwoven fabric, resulting in poor treatment effect.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed an automated integrated electrostatic electret device for meltblown nonwoven fabric, in order to achieve a more practical purpose. Utility Model Content

[0006] The purpose of this invention is to provide an automated, integrated electrostatic electret device for meltblown nonwoven fabrics to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automated integrated electrostatic electret device for meltblown nonwoven fabric, comprising an electrostatic treatment box, an electrostatic treatment mechanism, and a vertical spring rod assembly. The electrostatic treatment box has side sliding grooves on both sides, and a vertical spring rod assembly is installed on the outer bottom of the side sliding grooves. An adjustable roller is sleeved on the top of the vertical spring rod assembly, and a limit ring is provided at the connection between the outer wall of the adjustable roller's shaft and the outer wall of the electrostatic treatment box. The adjustable roller forms an up-and-down sliding structure through the limit ring and the side sliding grooves. A hot air blower is provided at the bottom of the feed inlet of the electrostatic treatment box, and a feeding roller assembly is provided on the horizontal outer side of the hot air blower. A hot air outlet plate is provided at the top corner of the hot air blower. Transmission rollers are symmetrically arranged inside the electrostatic treatment box, and two sets of transmission rollers are positioned on either side of the adjustable roller. A blower is provided on one side inside the electrostatic treatment box, and the electrostatic treatment mechanism is installed above the blower.

[0008] The electrostatic treatment mechanism includes an air inlet cylinder, a guide plate, an arc groove, and an electrostatic eliminator. The bottom of the air inlet cylinder is connected to the guide plate, and an arc groove is formed in the middle of the guide plate. An electrostatic eliminator is engaged with the inner side of the arc groove.

[0009] The guide plate and the set of transmission rollers are positioned in a coordinated manner, and a vacuum cleaner is installed at the top end of the electrostatic treatment box away from the feeding roller set.

[0010] Furthermore, a rotating buckle is engaged on the inner side of the electrostatic treatment box, and the rotating buckle is positioned above the feeding roller assembly.

[0011] Furthermore, the electrostatic treatment box has a discharge port on the outer wall side near the blower.

[0012] Furthermore, the drainage plate is connected to the electrostatic eliminator through an arc groove, and the bottom of the drainage plate is arranged in an arc shape.

[0013] Furthermore, the electrostatic treatment box is elastically connected from top to bottom by a vertical spring rod assembly and an adjustable roller.

[0014] Furthermore, the meltblown nonwoven fabric is bonded to the surface of the hot air outlet plate and passes through the left-side transfer roller, the adjustable roller, and the right-side transfer roller in an S-shape.

[0015] This utility model provides an automated, integrated electrostatic electret device for meltblown nonwoven fabrics, which has the following advantages:

[0016] 1. This utility model uses a feeding roller group, a left-side transmission roller, an adjustable roller, and a right-side transmission roller as transmission components to enable the meltblown nonwoven fabric to be transported in a roller-like manner. The feeding roller group and the left-side transmission roller, located at the initial position, are connected by a hot air outlet plate for limiting and supporting the meltblown nonwoven fabric. In conjunction with the hot air fan behind the hot air outlet plate, the principle of thermal expansion is used to increase the fluffiness of the meltblown nonwoven fabric body, thereby increasing the affinity and contact between the meltblown nonwoven fabric body and the electric field.

[0017] The bonded structure of the hot air outlet plate and the meltblown nonwoven fabric can further enhance the preheating of the meltblown nonwoven fabric body, making it more fluffy and easier for subsequent static elimination operations.

[0018] 2. In this utility model, the adjustable roller is provided with elastic telescopic structures on both sides. The adjustable roller is vertically supported by a vertical spring rod group. When the meltblown nonwoven fabric is conveyed by being attached to the upper surface of the adjustable roller, it can elastically support the meltblown nonwoven fabric, keeping the meltblown nonwoven fabric in a taut state, which facilitates the stability of the meltblown nonwoven fabric during transmission.

[0019] 3. In this utility model, the right-side conveying roller serves as a conveying guide for meltblown nonwoven fabric. An electrostatic treatment mechanism is installed above it, which consists of an air inlet cylinder, a diversion plate, and an electrostatic eliminator. The electrostatic eliminator is positioned above the conveying roller and can generate a large number of ions with positive and negative charges. These ions are blown out at high speed by the gas input from the air inlet cylinder and, guided by the diversion plate, can neutralize the charge on the fabric to eliminate static electricity generated during the conveying process.

[0020] 4. In this utility model, the end position of the electrostatic treatment box allows the blower and vacuum cleaner to work together to extract and absorb dust and meltblown nonwoven fabric lint, clean the meltblown nonwoven fabric, reduce the adsorbed substances on the meltblown nonwoven fabric, and lower the probability of static electricity generation.
