Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a dipping and coating device for a probiotic nonwoven fabric production line. Background Technology

[0002] Probiotics are live microorganisms. Lactobacilli, which they contain, are the most abundant bacteria in a normal woman's vagina. They produce lactic acid, hydrogen peroxide, and some enzymes, playing a crucial role in maintaining a stable vaginal microecological environment. Therefore, it is generally believed that adding probiotics can enhance the efficacy of sanitary napkins, maintain vaginal flora balance, and ensure a healthy female reproductive environment. Non-woven fabric is a type of non-woven material. It is made by directly forming fibers from polymer chips, short fibers, or filaments into a web through airflow or mechanical means, then reinforcing it through hydroentangling, needle punching, or thermal rolling, and finally finishing it. It is a new type of fiber product with softness, breathability, and a planar structure. Its advantages include no fiber shedding, strength, durability, softness, and it also acts as a reinforcing material, while having a cotton-like feel.

[0003] In the probiotic nonwoven fabric production line, the dip coating device can combine probiotics with protective materials to form a uniform coating.

[0004] The existing dipping and coating equipment used in probiotic nonwoven fabric production lines has some shortcomings. First, it does not have a flexible beating mechanism, so it cannot be used to bend the nonwoven fabric back and forth during the dipping and coating process, resulting in an unsatisfactory dipping effect. Second, it does not have an anti-pull mechanism, so it cannot prevent fiber damage caused by pulling during the flexible beating.

[0005] In view of this, the inventors hope to optimize and improve the existing dip coating equipment used in probiotic nonwoven fabric production lines. Summary of the Invention

[0006] The purpose of this invention is to overcome the aforementioned problems in traditional technologies and provide a dipping and coating device for a probiotic nonwoven fabric production line.

The flexible striking mechanism for striking the nonwoven fabric during the dipping and coating process is installed in the middle of the dipping and coating tank. An anti-tear mechanism for preventing the nonwoven fabric from being pulled is installed around the flexible striking mechanism in the dipping and coating tank.

[0008] Furthermore, in the above-mentioned dipping and coating device for the probiotic nonwoven fabric production line, the flexible tapping mechanism includes two tapping units arranged side by side. Each tapping unit includes a support box, a flip drive motor, a first bevel gear set, a support horizontal shaft, a support plate, and flexible tapping plates. The support box and support plate are fixed to the side plate of the dipping and coating tank. The flip drive motor is installed in the support box. The output shaft of the flip drive motor is connected to the support horizontal shaft via the first bevel gear set. The support horizontal shaft is provided with movable support by two support plates. Several flexible tapping plates with different orientations are staggered on the support plates. The two flexible tapping plates opposite to each other in the two tapping units have opposite orientations.

[0009] Furthermore, in the above-mentioned dipping and coating device for the probiotic nonwoven fabric production line, the support box is provided with a movable cavity that facilitates the movement of the first umbrella-shaped steering gear set and the supporting horizontal shaft.

[0010] Furthermore, in the above-mentioned dip coating device for the probiotic nonwoven fabric production line, the flexible striking plate is made of rubber material, and the flexible striking plate can continuously and intermittently strike the nonwoven fabric strip when it rotates with the horizontal axis of the support.

[0011] Furthermore, in the aforementioned impregnation device for a probiotic nonwoven fabric production line, the anti-pull mechanism includes a base plate, a screw drive motor, a second bevel gear set, a screw, a gearbox, protrusions, a screw section, a movable stand, supporting rollers, a fixed clamping roller, a movable clamping roller, a clamping drive push rod, a push plate, a fixed stand, and a guide roller. A screw drive motor is fixed to the upper side of the base plate, and a gearbox and protrusions on both sides are installed on the lower side of the base plate. The gearbox and the protrusions on both sides jointly rotatably support the screw. The middle of the screw is connected to a second... The bevel steering gear set is connected to the output shaft of the lead screw drive motor. The lead screw has two sections with opposite directions of rotation. A movable stand is sleeved on the outer side of each lead screw section. The movable stand has a support roller, a fixed clamping roller and a movable clamping roller installed from bottom to top. The clamping drive push rod is fixed to the upper side of the movable stand. The movable end of the clamping drive push rod drives the movable clamping roller to move vertically via a push plate. Fixed stands are symmetrically installed on the lower side of the base plate near both ends. Two guide rollers are installed side by side on the fixed stands.

[0012] Furthermore, in the above-mentioned dipping and coating device for the probiotic nonwoven fabric production line, the upper part of the movable stand is provided with a screw groove that cooperates with the corresponding screw section, the top of the movable stand abuts against the lower side of the substrate, and the support roller can roll along the bottom surface of the inner cavity of the dipping tank.

[0013] Furthermore, in the above-mentioned dipping and coating device for the probiotic nonwoven fabric production line, the push plate is a grooved plate, and the movable stand is designed to facilitate the opening of adjustment grooves for the vertical displacement of the convex shafts on both sides of the movable clamping roller.

[0015] The beneficial effects of this utility model are: This utility model device is rationally designed, mainly consisting of an impregnation tank, a flexible striking mechanism, and an anti-tear mechanism. The flexible striking mechanism uses intermittent flexible striking plates arranged vertically to intermittently strike the nonwoven fabric strip during the impregnation process, thereby improving the impregnation effect of the nonwoven fabric strip. Simultaneously, to prevent fiber damage caused by excessive pulling during the striking process, an anti-tear mechanism is installed around the flexible striking mechanism. This anti-tear mechanism uses a bidirectional screw to bring two movable uprights closer together, causing the held nonwoven fabric strip to "wrinkle." This prevents excessive pulling during the striking process. After each section of the strip is struck, the movable uprights release their grip and return to their original position. An external traction mechanism then moves the nonwoven fabric strip a certain distance, allowing for the next anti-tear and striking operation. This method satisfies the striking and anti-tear requirements of the nonwoven fabric strip during the impregnation process.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0023] In this embodiment, the flexible striking plate 206 is made of rubber material. When the flexible striking plate 206 rotates with the horizontal axis 204 of the support, it can continuously and intermittently strike the non-woven fabric strip.

[0024] In this embodiment, the anti-pull mechanism 3 includes a base plate 301, a lead screw drive motor 302, a second bevel steering gear set 303, a lead screw 304, a gear box 305, protrusions 306, a lead screw section 307, a movable stand 308, a support roller 309, a fixed clamping roller 310, a movable clamping roller 311, a clamping drive push rod 312, a push plate 313, a fixed stand 314, and a guide roller 315.

Simultaneously, to prevent fiber damage caused by excessive stretching during the striking process, an anti-tear mechanism 3 is installed around the flexible striking mechanism 2. Structure 3 uses a bidirectional lead screw to bring the two movable uprights closer together, thereby causing the clamped nonwoven fabric strip 4 to "wrinkle". This way, the flexible hammering mechanism 2 will not cause large pulling when hammering. After each section of the strip is hammered, the movable upright releases the clamp on the nonwoven fabric strip 4 and resets. The external traction mechanism is used to move the nonwoven fabric strip a certain distance, so that the next anti-pulling and hammering operation can be performed. In this way, the hammering and anti-pulling requirements of the nonwoven fabric strip 4 during the impregnation and coating process are met.
