Description

Technical Field

[0001] The utility model relates to a processing device for female seamless underwear, and more particularly to an underwear fitting machine capable of quickly replacing underwear grooves. Background Art

[0002] At present, women's seamless underwear usually includes an underwear body and other parts, among which the underwear body is brushed with a layer of glue on the inner side of the outer layer of the underwear body or the outer surface of the inner layer of the underwear body (referring to the sides of the two relative to each other), and then the outer layer of the underwear body and the inner layer of the underwear body are pressed together to make the underwear body. Its structure from outside to inside is the outer layer of the underwear body, the glue layer, and the inner layer of the underwear body.

[0003] Therefore, the production of seamless underwear for women usually requires applying a layer of glue to the inner side of the outer layer of the underwear body (or the outer surface of the inner layer of the underwear body) using glue-brushing equipment at a glue-brushing station, and then moving the underwear body to a laminating station to laminarize the inner layer of the underwear body (or the outer layer of the underwear body). For example, a seamless underwear glue-brushing and laminating machine disclosed in Chinese patent document "Seamless underwear glue-brushing and laminating machine" with publication number CN220326857U includes a first workbench, a conveying mechanism, a second workbench, a turning mechanism, a lifting mechanism, a driving module, and a glue-brushing mechanism.

[0004] However, to facilitate the rapid and accurate positioning of the outer and inner layers of underwear, the aforementioned seamless underwear gluing and laminating machine requires a top surface of the first workbench (for quickly and accurately placing the inner or outer layer of the underwear), and top and bottom surfaces of the second workbench (for the outer or inner layer of the underwear). However, if the shape, size, or other parameters of the underwear body change, the first and second workbench must be replaced, as the underwear grooves are machined directly into their surfaces.

[0005] To this end, people have made some improvements to the workbench, such as designing the workbench to be easily disassembled so that the workbench with corresponding underwear grooves can be replaced according to the different contours of the underwear body. The Chinese patent document "A glue dispensing machine for seamless underwear that is easy to position" with the announcement number CN219683106U discloses a glue dispensing machine. Although the glue application device used by this device is different from the glue application device used by the laminating machine of this application, this technology also requires the use of a clothes placing board with underwear grooves. Therefore, this technology uses positioning columns and positioning grooves that can cooperate with each other to quickly complete the replacement and positioning of the clothes placing board, so as to achieve the purpose of quickly replacing the clothes placing board according to the different contours of the underwear body. However, this approach requires the manufacture of clothes placing boards according to different underwear contours. Once the number of underwear increases, the cost of replacing the clothes placing boards is high, and each replacement of the clothes placing boards requires a lot of manpower and material resources. Utility Model Content

[0006] The purpose of this utility model is to provide an underwear fitting machine with a quick-change underwear groove. This underwear fitting machine can quickly and easily change the underwear groove according to the changes in the underwear body contour, and it is low-cost. The technical solution adopted is as follows:

[0007] The invention relates to an underwear fitting machine capable of quickly replacing underwear grooves, comprising a frame and a glue-brushing device, a reversible upper mold unit, and a liftable lower mold unit respectively mounted on the frame. The glue-brushing device, the reversible upper mold unit, and the liftable lower mold unit are arranged in sequence from top to bottom, and are characterized in that: the top surface of the reversible upper mold unit is provided with a first underwear groove, the bottom surface of the reversible upper mold unit is provided with a second underwear groove, after the reversible upper mold unit is flipped 180 degrees in the vertical direction, the second underwear groove coincides with the first underwear groove when the reversible upper mold unit is not flipped; the underwear fitting machine also comprises a vacuum pumping device mounted on the frame, the reversible upper mold unit comprises a reversible mold body, a first underwear groove plate, and a second underwear groove plate, the reversible mold body has a hollow inner cavity, and the top and bottom surfaces of the reversible mold body are respectively provided with a plurality of through holes for connecting the outside world with the inner cavity. The rotating mold body has a rotating shaft on each of its left and right sides. One of the rotating shafts has an air hole connected to the inner cavity, and the outer end of the air hole is connected to a vacuum device. A first underwear slot is defined in the middle of a first underwear slot plate and is mounted on the top surface of the reversible mold body. A first underwear slot is formed between the first underwear slot and the top surface of the reversible mold body (during operation, the through-hole on the top surface of the reversible mold body located in the first underwear slot attracts the outer layer or inner layer of the underwear body placed in the first underwear slot). A second underwear slot is defined in the middle of a second underwear slot plate and is mounted on the bottom surface of the reversible mold body. A second underwear slot is formed between the second underwear slot and the bottom surface of the reversible mold body (during operation, the through-hole on the bottom surface of the reversible mold body located in the second underwear slot attracts the outer layer or inner layer of the underwear body placed in the second underwear slot). In other words, after the reversible upper mold unit is flipped, the second underwear slot moves to the position of the first underwear slot (when the reversible upper mold unit is not flipped), while the first underwear slot moves to the position of the second underwear slot (when the reversible upper mold unit is not flipped).

[0008] In a more preferred solution, the top and bottom surfaces of the reversible mold body are covered with through holes.

[0009] In a preferred embodiment, the thickness of the first underwear groove plate is greater than or equal to the thickness of the outer layer of the underwear body or the thickness of the inner layer of the underwear body; the thickness of the second underwear groove plate is greater than or equal to the thickness of the outer layer of the underwear body or the thickness of the inner layer of the underwear body.

[0010] In a preferred embodiment, a sponge layer is installed on the top surface of the lower mold unit. The purpose of using the sponge layer is to facilitate the outer layer of the underwear body to fit the inner layer of the underwear body when the top surface of the lower mold unit is pressed against the reversible upper mold unit.

[0011] In a more preferred solution, the top surface of the sponge layer is provided with a plurality of marking lines, which facilitate the operator to quickly place the outer layer or inner layer of the underwear body in the correct position.

[0012] Compared with the prior art, the beneficial effect of the present invention is that, since the first and second underwear groove plates that can be quickly disassembled are used in conjunction with the hollow mold with through holes on the top and bottom surfaces to replace the mold of the integrated structure, the underwear groove can be replaced conveniently and quickly according to the change of the contour of the underwear body, and the cost is low; and the sponge layer is installed on the top surface of the liftable lower mold unit, so that when the top surface of the liftable lower mold unit is against the flip-up upper mold unit, the outer layer of the underwear body and the inner layer of the underwear body can fit better.

[0024] like Figure 1 As shown in the figure, in an optional embodiment of the present application, the top surface of the sponge layer 401 is provided with a plurality of marking lines 402. The marking lines 402 facilitate the operator to quickly position the outer or inner layer of the underwear body in the correct position. Furthermore, if the outline of the underwear changes, the operator can quickly and easily redraw the marking lines 402 on the top surface of the sponge layer 401 to correspond to the outline of the underwear.

[0025] The following combination Figure 1-4 Introduce the working process:

[0026] 1. The operator places the outer layer of the underwear into the first underwear groove 301 on the top surface of the reversible upper mold unit 3. The vacuum device operates, and the through holes 306 in the first underwear groove 301 suck the outer layer of the underwear. The operator then places the inner layer of the underwear on the top surface of the lower mold unit 4 (using the marking line 402 to quickly put the inner layer of the underwear into the correct position).

[0027] 2. The glue-brushing device 2 presses against the top surface of the reversible upper mold unit 3, and then brushes a layer of glue on the inner side of the outer layer of the underwear body, and then returns to its original position;

[0028] 3. Flip the reversible upper mold unit 3 180 degrees;

[0029] 4. The lower mold unit 4 rises until it contacts the upper mold unit 3, pressing the outer layer of the underwear body with the inner layer of the underwear body to form the underwear body;

[0030] 5. The vacuum device stops working, and the underwear body falls onto the top surface of the lowerable mold unit 4, and the operator takes the underwear body away.

[0031] The manufacturing of the underwear body can be completed continuously in this way over and over again.

[0032] When the parameters such as the outline and size of the underwear body change, the operator can quickly replace the first underwear groove plate 304 and the second underwear groove plate 305 corresponding to the underwear body, and draw new multiple marking lines 402 corresponding to the underwear outline on the top surface of the sponge layer 401. The whole process is very convenient, fast, and low-cost, greatly reducing the manpower, material resources and time consumed.
