Description

Technical Field

[0001] This utility model relates to the field of underwear adhesive technology, and in particular to a circular dot-applying device. Background Technology

[0002] In modern underwear manufacturing processes, the glue application process is crucial, as it relates to the quality, wearing experience, and functionality of underwear. The emergence of glue application devices for underwear has greatly improved production efficiency and product quality, enabling precise application of silicone and other adhesives to specific areas of underwear, such as the waistband and cuffs, to enhance their elasticity, anti-slip properties, and fit.

[0003] Currently, there are various circular silicone coating devices for underwear on the market. These devices typically use automated mechanical structures to evenly apply liquid silicone to the corresponding areas of the underwear. However, a significant problem has emerged in actual use: after coating, the silicone relies mainly on natural cooling to set, a relatively slow process. During this period before the silicone is fully set, the silicone layer on the underwear is in a viscous state, making it extremely prone to sticking. This causes the underwear to adhere to each other, affecting not only the product's appearance but also potentially damaging the integrity of the silicone coating. Furthermore, due to the slow cooling, the bond between the silicone and the underwear fabric is not strong enough, making it prone to detachment during subsequent processing, transportation, or wear. This severely reduces the quality and lifespan of the underwear, increases production costs for manufacturers, and negatively impacts the consumer experience. Utility Model Content

[0004] In order to overcome the problem that the silicone coating on underwear is easy to stick or fall off due to the slow natural cooling and setting of the silicone after coating, the present invention provides a circular dot application device.

[0005] The technical solution is as follows: A circular dotting device includes a cooling and setting table assembly, a transmission roller assembly, and a three-axis adjustable dispensing assembly; the transmission roller assembly is located at the upper end of the cooling and setting table assembly; the three-axis adjustable dispensing assembly is located above the transmission roller assembly; the cooling and setting table assembly includes a setting fan, a lead screw slide rail, a cooling blower, and an air inlet grille; the lead screw slide rail is located at the upper end of the setting fan; cooling blowers are located on both sides of the lead screw slide rail; and an air inlet grille is located at the rear end of the setting fan.

[0006] Furthermore, the input end of the cooling blower is connected to the air intake grille via a pipe; the output end of the cooling blower is located on the upper surface of the shaping fan.

[0007] Furthermore, the transmission roller assembly includes a processing table, an underwear dispensing roller shaft, and a slide rail connector; the three-axis adjustable dispensing assembly includes a three-axis gantry screw and a dispensing valve.

[0008] Furthermore, a processing table is provided at the upper end of the lead screw slide rail; a slide rail connector is provided at the lower end of the processing table, and the slide rail connector is fixedly connected to the processing table.

[0009] Furthermore, the slide rail connector slides along the track inside the lead screw slide rail, and the lead screw shaft inside the lead screw slide rail is connected to the slide rail connector via lead screw drive.

[0010] Furthermore, both sides of the processing table are equipped with underwear dispensing roller shafts, and the output ends of four independent servo motors inside the processing table are connected to the underwear dispensing roller shafts for transmission.

[0011] Furthermore, a dispensing valve is installed above the processing table; a three-axis gantry screw is installed at the rear end of the dispensing valve, and the output end of the three-axis gantry screw is fixedly connected to the housing of the dispensing valve.

[0012] The beneficial effects are as follows: This utility model first places the underwear on a single or two underwear dispensing roller shafts on the same side. The servo motor inside the processing table drives the underwear dispensing roller shaft to rotate synchronously. At the same time, the three-axis gantry screw dynamically adjusts the position of the dispensing valve so that the dispensing valve is located above the underwear fabric above the underwear dispensing roller shaft. Then, the dispensing valve applies hot-melt silicone to the underwear fabric. With the horizontal adjustment of the three-axis gantry screw, the silicone coating trajectory changes and a pattern coating function is achieved. The underwear rotates once synchronously on the underwear dispensing roller shaft, thus completing one cycle of silicone coating processing. The cooling blower filters the outside air through the air intake grille and blows it upwards, so that the silicone coating on the fabric below the underwear dispensing roller shaft is quickly cooled and set, thus achieving the rapid air-cooling and setting function of the silicone layer and effectively preventing the silicone layer from falling off due to cooling.

[0013] By setting the dispensing valve and adopting a single screw structure, the rotor and stator form a self-sealing structure using the single screw volumetric conveying principle. The rotor pushes the material under the directional rotation of the stator cavity, realizing the hot melt silicone conveying function. The inner wall of the stator cavity is equipped with an electric auxiliary heating layer to heat the silicone flowing inside and prevent it from cooling and solidifying to block the conveying pipeline.

[0014] With the transmission roller assembly, four independent servo motors inside the processing table drive the rotation of four underwear dispensing roller shafts, which rotate the underwear fabric onto the dispensing roller shafts. Combined with the dispensing and coating process of the three-axis adjustable dispensing assembly, the dispensing process of the underwear around the circumference is realized. The structure is simple and the operation is convenient. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] Example 1: As Figures 1-5 As shown, the circular dotting device includes a cooling and shaping table assembly 1, a transmission roller assembly 2, and a three-axis adjustable dispensing assembly 3. The transmission roller assembly 2 is located at the upper end of the cooling and shaping table assembly 1. The three-axis adjustable dispensing assembly 3 is located above the transmission roller assembly 2. The cooling and shaping table assembly 1 includes a shaping fan 101, a lead screw slide rail 102, a cooling blower 103, and an air inlet grille 104. The lead screw slide rail 102 is located at the upper end of the shaping fan 101. Cooling blowers 103 are located on both sides of the lead screw slide rail 102. An air inlet grille 104 is located at the rear end of the shaping fan 101.

[0023] The input end of the cooling blower 103 is connected to the air intake grille 104 via a pipe; the output end of the cooling blower 103 is located on the upper surface of the shaping blower 101.

[0024] The transmission roller assembly 2 includes a processing table 201, an underwear dispensing roller shaft 202, and a slide rail connector 203; the three-axis adjustable dispensing assembly 3 includes a three-axis gantry screw 301 and a dispensing valve 302.

[0025] The upper end of the lead screw slide rail 102 is provided with a processing table 201; the lower end of the processing table 201 is provided with a slide rail connector 203, and the slide rail connector 203 is fixedly connected to the processing table 201.

[0026] The slide rail connector 203 is slidably connected along the track inside the lead screw slide rail 102, and the lead screw shaft inside the lead screw slide rail 102 is connected to the slide rail connector 203 for lead screw transmission.

[0027] A dispensing valve 302 is installed above the processing table 201; a three-axis gantry screw 301 is installed at the rear end of the dispensing valve 302, and the output end of the three-axis gantry screw 301 is fixedly connected to the housing of the dispensing valve 302.

[0028] First, the underwear is placed on a single or two underwear dispensing rollers 202 on the same side. The servo motor inside the processing table 201 drives the underwear dispensing rollers 202 to rotate synchronously. At the same time, the three-axis gantry screw 301 dynamically adjusts the position of the dispensing valve 302, so that the dispensing valve 302 is located above the underwear fabric above the underwear dispensing rollers 202. The dispensing valve 302 adopts a single screw structure and utilizes the single screw volumetric conveying principle. The rotor and stator form a self-sealing structure. The rotor pushes the material under the directional rotation of the stator cavity, realizing the hot melt silicone conveying function. The inner wall of the stator cavity is provided with an electric auxiliary heating layer to heat the silicone flowing inside and prevent it from cooling down. After the material conveying pipeline is blocked, the dispensing valve 302 applies the hot-melt silicone to the underwear fabric. The horizontal adjustment of the three-axis gantry screw 301 enables the silicone coating trajectory to change and form a pattern. The underwear rotates once synchronously with the underwear dispensing roller shaft 202, thus completing one cycle of silicone coating processing. The cooling blower 103 filters external air through the air intake grille 104 and blows it upwards, so that the silicone coating on the fabric below the underwear dispensing roller shaft 202 is quickly cooled and set, thus achieving the rapid air-cooling and setting function of the silicone layer and effectively preventing the silicone layer from falling off due to cooling.

[0029] Example 2: Based on Example 1, such as Figures 1-5 As shown, both sides of the processing table 201 are provided with underwear dispensing roller shafts 202, and the output ends of the four independent servo motors inside the processing table 201 are connected to the underwear dispensing roller shafts 202 for transmission.

[0030] With the transmission roller assembly 2 in place, four independent servo motors inside the processing table 201 drive the rotation of four underwear dispensing roller shafts 202 respectively, so that the underwear fabric is placed on the underwear dispensing roller shafts 202 and rotated. In conjunction with the dispensing and coating process of the three-axis adjustable dispensing assembly 3, the dispensing process of the underwear around the whole circle is realized. The structure is simple and the operation is convenient.
