Description

Technical Field

[0001] This utility model relates to the field of children's smock production, and more particularly to disposable children's smock production equipment. Background Technology

[0002] During the stage of independent feeding for toddlers, their fine motor skills are not yet fully developed, often resulting in food falling onto their clothes or the floor. This not only increases the cleaning workload for parents but also affects the hygiene of the dining environment. To alleviate this problem, current technology generally adopts a foldable or three-dimensional bib structure on the front of the toddler's smock, which catches any food scraps that fall, thereby reducing contamination of clothes and the floor.

[0003] However, existing smocks are all reusable, which have many hard-to-clean areas where food residue can easily remain, leading to mold growth and affecting the health of infants and young children. Furthermore, existing smocks are all handmade, which is labor-intensive and has low production efficiency. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a fully automated disposable children's smock production equipment, thereby improving production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a disposable children's smock production equipment, comprising a frame, on which a feeding device, a cutting device, a folding device, a welding device, a slitting device, and a collecting platform are sequentially arranged along the direction of roll material travel; the feeding device includes an unwinding shaft for continuously unwinding non-woven fabric rolls; the cutting device includes a neckline cutting section for punching out a ring-shaped cut line on the roll material; the folding device includes a back folding plate for folding the back placket area inward and a bib folding plate for folding the lower part of the roll material inward to form a bib; the welding device is used to weld the front placket and back placket and to perform ultrasonic welding on the bib edge; the slitting device includes a forming cutting component for longitudinally slitting the roll material into single-piece smock products; and the collecting platform is used to collect the single-piece smock products.

[0006] The feeding device of this utility model provides continuous roll material. The neck cutting part of the cutting device forms a neck ring-shaped cut line at the corresponding position of the roll material. Tearing along the neck ring-shaped cut line can form a neck opening. The waste material at the neck opening and the roll material are connected by the cut line, which can also ensure the tension of the roll material. After the cut line, the roll material passes through the back folding plate and the bib folding plate of the folding device, causing the corresponding parts to fold inward to form the back folding area and the bib area. Then, the welding device welds and fixes the roll material into shape. The cutting device cuts along the intersection line of the sleeve welding line and the bib welding line, separating the bib with the bib from the roll material, realizing the fully automatic production of the bib and reducing costs.

[0007] Preferably, the neckline cutting section includes an annular cutting section forming a circular break line at the neck and a U-shaped cutting section forming a break line at the headband, with the annular cutting section positioned in the middle of the U-shaped cutting section. This design can be used to produce smocks with headbands, allowing the headbands to be adjusted to accommodate children of different ages.

[0008] Furthermore, the cutting device also includes a back flap cutting section, which forms a split line in the back flap area of ​​the roll material, allowing the back flap to be torn open during use to allow the arm to be inserted. This can be used to produce smocks with split line cuts in the back flap area, allowing for easy wearing by tearing the back flap along the split line.

[0009] Furthermore, the cutting device also includes a belt cutting section, which is used to punch out the belt cut lines on the roll material. By first cutting the corresponding positions and then folding the edges, there is no need to add a separate strap feeding device; the strap only needs to be cut and shaped on the roll material, making the structure simpler.

[0010] Preferably, the collar cutter, waistband cutter, and back panel cutter are all mounted on the first drive roller, and a first passive roller for supporting the material is located below the first drive roller. This reduces costs and shortens the production line.

[0011] Preferably, the slitting device includes a second driving roller and a second driven roller disposed within the archway. The forming cutter component is disposed on the second driving roller, and a driven gear is provided at the end of the second driving roller. The driven gear is connected to the driving gear of the power source, and the axes of the driven gear and the driving gear are arranged horizontally parallel. The horizontal arrangement of the axes of the driven gear and the driving gear avoids the up-and-down adjustment of the driving roller during gear meshing, and also avoids the serious off-center load problem caused by directly mounting the heavy power source on one end of the second driving roller.

[0012] Preferably, the welding device is a circular-to-circular welding or a circular-to-flat welding.

[0013] Preferably, the collection platform includes a circular conveyor belt. The conveyor belt delivers the formed materials one by one, facilitating collection. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0020] See Figure 1A disposable children's smock production equipment includes a frame. Along the direction of roll material travel, the frame is sequentially equipped with: a feeding device 1, a cutting device 2, a folding device 3, a welding device 4, a slitting device 5, and a collection platform 6. The feeding device 1 is located upstream of the frame and is used to continuously release non-woven fabric rolls. The feeding device 1 includes a roll material holder 7, on which roll material 7 is placed. The roll material 7 can be plastic film or non-woven fabric, etc. The cutting device 2 is located downstream of the feeding device 1. The cutting device 2 includes a neckline cutting section 21 for punching out a neck ring-shaped break line 71 on the roll material. The blade of the neckline cutting section 21 has an intermittent serrated structure. After cutting, a ring-shaped break line consisting of a series of tiny connecting points is formed on the roll material. During use, the roll material is torn along the neck ring-shaped break line 71 to form a neckline. The neck waste is connected to the roll material 7 at the break line, maintaining the tension of the roll material 7. The folding device 3 is located downstream of the cutting device 2. The folding device 3 includes a back flap folding plate 31 for folding the back flap area 75 inward and a folding plate 32 for folding the lower part of the roll material inward to form a folding plate. The back flap folding plate 31 and the folding plate 32 are located on the front and rear sides of the frame. The roll material 7 folds the front side portion inward along the back flap folding plate 31 to form the back flap area 75. At the same time, the roll material 7 folds the rear side portion inward along the folding plate 32 to form the folding plate area 76. The area of ​​the back flap area 75 is not less than that of the folding plate area 76. Welding device 4 is located downstream of the folding device 3 and is used to weld the front and back flaps and perform ultrasonic welding on the edge of the bib. Welding device 4 is either a round-to-round welding or a round-to-flat welding method, where the pressing part is in the form of a roller, and the welding part is either flat (round-to-flat) or roller (round-to-round). Both methods can achieve welding of the continuously conveyed roll 7, welding the front and back flaps, and creating a left welding line 77 and a right welding line 78 on the roll 7 (see...). Figure 4 The left welding line 77 includes a left inclined segment 771 and a left straight segment 772. The left inclined segment has a gap between itself and the fold line formed by the back panel 31 on the roll 7, forming the left sleeve. The left straight segment 772 welds the left side of the bib area 76 to the front placket. The right welding line 78 includes a right inclined segment and a right straight segment 782. The right inclined segment has a gap between itself and the fold line formed by the back panel 31 on the roll 7, forming the right sleeve. The right straight segment 782 welds the right side of the bib area 76 to the front placket, thus forming the bib. The inclined and vertical segments of the welding lines can be continuous or discontinuous. The slitting device 5 is located downstream of the welding device 4. The slitting device 5 is a forming cutter component used to longitudinally slit the roll material into single-piece hoodie finished products. The finished product component includes an inverted U-shaped cutting segment 511 and a vertical cutting segment 512 (see...). Figure 4The inverted U-shaped cutting section 511 cuts out the main body of the hood along the left welding line 77 and the right welding line 78. The vertical cutting section 512 separates adjacent sleeves. The inverted U-shaped cutting is used to separate the waste material between adjacent hood bodies. The vertical cutting section 512 is located in the middle of the inverted U-shaped cutting section 511 and is used to separate the sleeve connection parts between adjacent hoods, realizing fully automatic forming of the hood with a bib and improving production efficiency. The collection platform 6 is used to collect the finished single-piece hood. The collection platform 6 can be a stationary platform or a conveyor platform, see [link to documentation]. Figure 1 The collection platform includes a circular conveyor belt. The conveyor belt delivers the formed materials one by one for easy collection.

[0021] To make the product manufactured by this utility model suitable for children of different ages, the collar cutting section 21 includes an annular cutting section 211 forming a ring-shaped break line 71 at the neck and a U-shaped cutting section 212 forming a drawstring break line 72. The annular cutting section 211 is located in the middle of the U-shaped cutting section 212. The blades of the annular cutting section 211 and the U-shaped cutting section 212 have an intermittent serrated structure. The annular break line 71 formed by the annular cutting section 211 on the roll material 7 allows consumers to tear off excess waste material along it to form a collar. The drawstring break line 72 formed by the U-shaped cutting section 212 on the roll material 7 allows consumers to tear it along it to form a drawstring. The drawstring can be adjusted to suit children of different ages. A point-cutting section can also be provided between the U-shaped cutter section 212 and the annular cutter section 211. The point-cutting section is aligned with the central axis of the U-shaped cutter section 212 to point-cut the headband. When in use, the headband can be split in half to form a neck tie, which makes it easy to adjust the neckline size.

[0022] For example, the cutting device 2 also includes a back flap cutting section 22, which is used to form a splitting line 73 in the back flap area 75 of the roll material. The splitting line 73 is a straight line, so that the back flap can be torn open during use to allow the arm to be inserted. The splitting line 73 divides the back flap area 75 in half, making it easier for the user to reach into the sleeve from the opening, making it more convenient to wear.

[0023] To ensure the practicality of the product manufactured under this invention, the cutting device 2 further includes a belt cutting section 23. This belt cutting section is used to cut a belt break line 74 on the roll material. After the back panel area 75 is divided, it is in a loose state during use. The belt cutting section is a point-cutting blade, wherein the belt break line 74 is relatively perpendicular to the dividing point break line 73. The belt break line 74 can be a continuous line, for example, the belt break line 74 has a gap with the bottom side of the back panel area 75 (forming a belt). Simultaneously, there is a gap between the endpoint of the belt break line 74 and the left straight segment 772 and the right straight segment 782, ensuring the belt connects to the overcoat. Alternatively, the belt break line 74 may be separated in the middle (see...). Figure 2 and Figure 4 The waistband break line 74 and the bottom side of the back placket area 75 have a gap (forming a waistband), and the middle gap ensures that the waistband is connected to the overcoat, and the waistband can ensure that the overcoat fits the body.

[0024] The collar cutting section 21, the belt cutting section 23, and the back panel cutting section 22 can be respectively mounted on different rollers via die-cutting sleeves. To shorten the production line and reduce production costs, the collar cutting section 21, the belt cutting section 23, and the back panel cutting section 22 are all mounted on the first drive roller (participating in...). Figure 2 Below the first active roller is a first passive roller for receiving material. The first active roller is connected to a rotary power source. The collar cutter 21, the waist belt cutter 23 and the back panel cutter 22 are arranged on the same roller, and the die cutting is completed in one step. At the same time, continuous die cutting is achieved through the cooperation of the first active roller and the first passive roller, which is more efficient.

[0025] See Figure 3 To improve forming and die-cutting efficiency and ensure die-cutting quality, the slitting device 5 includes a second active roller 52 and a second passive roller 53 disposed within the archway 8. The second active roller 52 and the second passive roller 53 are arranged vertically opposite each other. The forming cutter component is disposed on the second active roller 52. A driven gear 55 is provided at the end of the second active roller 52. The driven gear 55 is connected to the active gear 54 of the power source. The axes of the driven gear 55 and the active gear 54 are arranged horizontally parallel. The second active roller 52 is rotatably mounted on the mounting block 81. The left and right sides of the mounting block 81 abut against the archway 8. The power source of the second active roller 52 is located on the side, ensuring uniform force on the second active roller 52 and extending its service life. In addition, it can prevent the second active roller 52 from jumping up and down due to gear transmission. Even if there is jumping, the second active roller 52 will jump horizontally and radially. The left and right sides of the mounting hole for mounting the second active roller 52 abut against the archway 8, which can limit the jumping to the greatest extent and make the second active roller 52 rotate stably, thereby ensuring the die-cutting quality.

[0026] The working principle of this utility model is described below with reference to the accompanying drawings: The feed device 1 unwinds the roll 7, which is then fed to the cutting device 2. The collar cutting section 21, the waistband cutting section 23, and the back panel cutting section 22 are simultaneously positioned on the first drive roller. As the first drive roller rotates, it forms a neck ring-shaped break line 71, a headband break line 72, a split break line 73, and a waistband break line 74 on the roll 7. The die-cutting of each part is completed in one step. In addition, the waste material is connected to the roll 7 at the break point to ensure stable conveying of the roll 7. Subsequently, the roll material 7 passes through the folding device 3, where the back flap folding plate 31 and the bib folding plate 32 fold the two sides of the roll material 7 inward. After folding, the roll material 7 passes through the welding device 4, where the front and back flaps are welded together, creating a left welding line 77 and a right welding line 78 on the roll material 7, forming the left and right sleeves and welding the bib area 76 to the front flap. After welding, the roll material 7 enters the slitting device 5, where the forming cutter cuts the roll material into individual smock products. Finally, the smock products are collected by the collection platform 6.
