Description

Technical Field

[0001] This utility model relates to the technical field of diaper processing equipment, specifically to a shaping and cutting device for diaper production. Background Technology

[0002] In today's market for maternal and infant care products, the diaper industry occupies a crucial position. With the continued growth of the global population, especially the steady increase in the number of newborns and the aging of the society, the market demand for diapers is showing a year-on-year upward trend. According to relevant market research reports, the global diaper market has been expanding continuously in recent years, with numerous brands vying for a share of the market, resulting in extremely fierce competition. In the production process, an efficient and stable production process is crucial to a company's competitiveness. On the one hand, efficient production allows companies to produce large quantities of products in a short period, quickly respond to market demands, and seize market share.

[0003] In traditional diaper production, the shaping and cutting processes are typically performed by separate equipment. The shaping stage requires specialized heat-pressing equipment to mold the diaper into its correct shape, ensuring a snug fit and good comfort. The cutting process, on the other hand, relies on a separate set of cutting equipment to precisely cut large sheets of diaper material into the appropriate size. This separate equipment layout not only occupies a significant amount of production space but also makes the production process lengthy and complex. Furthermore, because the equipment operates independently, the connections between them are often not smooth, easily leading to delays and deviations in material transfer, which in turn affects product quality and production efficiency.

[0004] From the perspective of the drive equipment, existing equipment requires multiple drive units to power the shaping and cutting equipment respectively. This not only increases the cost and maintenance difficulty of the equipment, but also significantly increases the overall energy consumption. In addition, the coordinated operation of multiple drive units is quite complicated, which requires a high level of technical skill from the operators, further limiting the improvement of production efficiency.

[0005] To address the aforementioned problems, this utility model proposes a shaping and cutting device for diaper production, including a processing platform with a slide for material movement and a mounting base at the rear of the processing platform; it also includes:

[0006] A feeding structure for conveying materials includes upper and lower feeding rollers. The rear wall of the feeding rollers is fixed with a feeding shaft that is rotatably connected to the mounting base. A storage platform is provided on the side of the feeding rollers away from the processing platform.

[0007] A shaping structure is provided above the processing platform. The shaping structure includes a shaping seat that is slidably connected to the mounting base. A hot press mold plate is installed at the bottom of the shaping seat. A shaping cam is provided above the shaping seat. The outer surface of the shaping cam contacts the top of the shaping seat. A shaping shaft that is rotatably connected to the mounting base is fixed to the rear wall of the shaping cam.

[0008] A cutting structure is provided above the processing platform. The cutting structure includes a cutting seat that is slidably connected to the mounting base. A cutting blade is installed at the bottom of the cutting seat. A cutting cam is provided above the cutting seat. The outer surface of the cutting cam contacts the top of the cutting seat. A cutting shaft that is rotatably connected to the mounting base is fixed to the rear wall of the cutting cam.

[0009] Furthermore, a servo motor is installed on the front wall of the mounting base. The output end of the servo motor is connected to a drive shaft. An incomplete spur gear is fixed on the outer side of the drive shaft. A connecting spur gear is fixed on the outer side of the feed shaft above. The connecting spur gear can mesh with the incomplete spur gear. Feeding spur gears are fixed on the outer sides of both feed shafts and mesh with each other. A linkage shaft is provided on the side of the connecting spur gear. A linkage spur gear that can mesh with the incomplete spur gear is fixed on the outer side of the linkage shaft. The linkage shaft and the shaping shaft are connected by a sprocket and chain A. The shaping shaft and the cutting shaft are connected by a sprocket and chain B.

[0010] Furthermore, when the incomplete spur gear rotates one revolution, it causes the linked spur gear to rotate one revolution as well.

[0011] Furthermore, each of the four corners of the shaping base is fixed with a shaping slide rod, and the top of the processing platform is provided with a shaping slide hole for the shaping slide rod to slide into. A shaping spring is fitted on the outer side of the shaping slide rod, and the top and bottom of the shaping spring are fixed to the shaping base and the processing platform, respectively.

[0012] Furthermore, each of the four corners of the cutting base is fixed with a cutting slide rod, and the top of the processing platform is provided with a cutting slide hole for the cutting slide rod to slide into. A cutting spring is fitted on the outer side of the cutting slide rod, and the top and bottom of the cutting spring are fixed to the cutting base and the processing platform, respectively.

[0013] Furthermore, a conveyor belt is installed on the side of the processing platform away from the feeding structure.

[0014] Furthermore, the front wall of the processing platform is provided with a sliding groove for the shaping seat and the cutting seat to slide up and down.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. The servo motor's output, through a drive shaft, incomplete spur gears, connecting spur gears, linkage spur gears, sprockets, and chains, sequentially transmits power to the feeding shaft, shaping shaft, and cutting shaft, achieving coordinated operation of the feeding, shaping, and cutting processes. The single-drive design reduces equipment costs and the number of parts, making maintenance simpler and more convenient. Simultaneously, the single-drive design allows for more precise control of the operating rhythm of each process, avoiding synchronization problems that may occur between multiple drive devices, further improving production efficiency.

[0017] 2. The material is conveyed through the cooperation of the feeding rollers and feeding shaft. The design of the hot pressing mold plate and the shaping cam ensures the uniformity and stability of hot pressing. The setting of the shaping slide rod and shaping spring makes the up-and-down sliding of the shaping seat more stable. The cooperation between the cutting blade and the cutting cam, as well as the use of the cutting slide rod and cutting spring, ensures the cutting accuracy and the flatness of the cut. The cutting process is more stable, reducing the occurrence of incomplete cutting or uneven cuts, and improving the product qualification rate. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] A shaping and cutting device for diaper production, such as Figure 1 As shown, the system includes a processing platform 1 with a slide for material movement and a mounting base 2 on the rear side of the processing platform 1. It also includes a feeding structure for conveying materials, which includes two feeding rollers 31, one above the other. The rear wall of the feeding rollers 31 is fixed with a feeding shaft 32 that is rotatably connected to the mounting base 2. A storage platform 33 is provided on the side of the feeding rollers 31 away from the processing platform 1, and a conveyor belt 14 is provided on the side of the processing platform 1 away from the feeding structure.

[0025] The processing platform 1 provides support and working space for the whole device, and the slide guides the movement of materials; the mounting base 2 is used to install components such as the feeding shaft 32; the feeding structure transports the materials on the placement platform 33 to the processing platform 1 by rotating the feeding roller 31; the conveyor belt 14 is responsible for transporting the processed diapers.

[0026] like Figure 1 As shown, in this embodiment, a shaping structure is provided above the processing platform 1. The shaping structure includes a shaping seat 41 that is slidably connected to the mounting base 2. A hot press mold plate 42 is installed at the bottom of the shaping seat 41. A shaping cam 43 is provided above the shaping seat 41. The outer surface of the shaping cam 43 contacts the top of the shaping seat 41. A shaping shaft 44 that is rotatably connected to the mounting base 2 is fixed to the rear wall of the shaping cam 43. A shaping slide rod 45 is fixed at each of the four corners of the shaping seat 41. A shaping slide hole is provided at the top of the processing platform 1 for the shaping slide rod 45 to be inserted and slid. A shaping spring 46 is sleeved on the outer side of the shaping slide rod 45. The top and bottom of the shaping spring 46 are fixed to the shaping seat 41 and the processing platform 1, respectively.

[0027] When the shaping cam 43 rotates, it pushes the shaping seat 41 to slide down, and the hot pressing mold plate 42 hot presses and shapes the material; the shaping slide rod 45 and the shaping slide hole ensure that the shaping seat 41 slides smoothly, and the shaping spring 46 provides the return force.

[0028] like Figure 1As shown, in this embodiment, a cutting structure is provided above the processing platform 1. The cutting structure includes a cutting seat 51 slidably connected to the mounting base 2. A cutting blade 52 is installed at the bottom of the cutting seat 51, and a cutting cam 53 is provided above the cutting seat 51. The outer surface of the cutting cam 53 contacts the top of the cutting seat 51, and a cutting shaft 54 ​​rotatably connected to the mounting base 2 is fixed to the rear wall of the cutting cam 53. Cutting slide rods 55 are fixed at each of the four corners of the cutting seat 51. A cutting slide hole is provided on the top of the processing platform 1 for the cutting slide rods 55 to slide into. A cutting spring 56 is sleeved on the outer side of the cutting slide rod 55. The top and bottom of the cutting spring 56 are fixed to the cutting seat 51 and the processing platform 1, respectively. A groove is provided on the front wall of the processing platform 1 for the shaping seat 41 and the cutting seat 51 to slide up and down.

[0029] The cutting cam 53 rotates to drive the cutting seat 51 to slide down, and the cutting blade 52 cuts the shaped material; the cutting slide bar 55 and the cutting slide hole ensure that the cutting seat 51 slides smoothly, the cutting spring 56 assists in resetting, and the slide groove provides a smooth up and down sliding track for the shaping seat 41 and the cutting seat 51.

[0030] like Figure 1 and Figure 2 As shown, in this embodiment, a servo motor is installed on the front wall of the mounting base 2. The output end of the servo motor is connected to a drive shaft 6. An incomplete spur gear 7 is fixed on the outer side of the drive shaft 6. A connecting spur gear 8 is fixed on the outer side of the previous feeding shaft 32. The connecting spur gear 8 can mesh with the incomplete spur gear 7. Feeding spur gears 9 are fixed on the outer sides of both feeding shafts 32 and mesh with each other. A linkage shaft 10 is provided on the side of the connecting spur gear 8. A linkage spur gear 11 that can mesh with the incomplete spur gear 7 is fixed on the outer side of the linkage shaft 10. The linkage shaft 10 and the shaping shaft 44 are connected by a sprocket and a chain A12. The shaping shaft 44 and the cutting shaft 54 ​​are connected by a sprocket and a chain B13. When the incomplete spur gear 7 rotates one revolution, the linkage spur gear 11 also rotates one revolution.

[0031] The servo motor serves as the power source, driving the incomplete spur gear 7 to rotate via the drive shaft 6. The incomplete spur gear 7 meshes sequentially with the connecting spur gear 8 and the linkage spur gear 11, driving the feeding shaft 32 and the linkage shaft 10 to rotate. The linkage shaft 10 then drives the shaping shaft 44 via a sprocket and chain A12. The shaping shaft 44, in turn, drives the cutting shaft 54 ​​via a sprocket and chain B13, thus realizing the power transmission for the feeding, shaping, and cutting processes.

[0032] The working principle of this utility model is as follows:

[0033] When the equipment is started, the servo motor begins to work, and its output drives the drive shaft 6 to rotate. The incomplete spur gear 7 on the drive shaft 6 rotates accordingly. When the incomplete spur gear 7 meshes with the connecting spur gear 8, it drives the upper feed shaft 32 to rotate. Since the feed spur gears 9 on the two feed shafts 32 are meshed, the two feed shafts 32 will rotate synchronously in opposite directions, thereby driving the upper and lower feed rollers 31 to rotate, and conveying the material on the placement platform 33 to the processing platform 1 through the slide.

[0034] The incomplete spur gear 7 continues to rotate, and when it meshes with the linkage spur gear 11, it drives the linkage shaft 10 to rotate. The linkage shaft 10 drives the shaping shaft 44 to rotate through the sprocket and chain A12, and the shaping cam 43 on the shaping shaft 44 rotates accordingly. Since the outer surface of the shaping cam 43 is in contact with the top of the shaping seat 41, when the shaping cam 43 rotates, it pushes the shaping seat 41 to slide downward, and the shaping slide rod 45 slides in the shaping slide hole, while compressing the shaping spring 46. The hot press mold plate 42 at the bottom of the shaping seat 41 performs hot press shaping on the conveyed material, so that the diaper is initially formed (when the shaping operation occurs on the diaper, the incomplete spur gear 7 does not mesh with the connecting spur gear 8, and the feeding operation is suspended, that is, the feeding process and the shaping process are intermittent). When the shaping cam 43 continues to rotate and no longer applies pressure to the shaping seat 41, the elastic force of the shaping spring 46 causes the shaping seat 41 to return to its original position.

[0035] Meanwhile, the shaping shaft 44 drives the cutting shaft 54 ​​to rotate via a sprocket and chain B13, causing the cutting cam 53 on the cutting shaft 54 ​​to rotate. The cutting cam 53 pushes the cutting seat 51 downward, and the cutting slide bar 55 slides in the cutting slide hole, simultaneously compressing the cutting spring 56. The cutting blade 52 at the bottom of the cutting seat 51 cuts the shaped material, cutting the diaper off the material. When the cutting cam 53 continues to rotate and no longer applies pressure to the cutting seat 51, the elastic force of the cutting spring 56 causes the cutting seat 51 to return to its original position.

[0036] After shaping and cutting, the diapers are conveyed onto conveyor belt 14 for the next packaging process. One rotation of the incomplete spur gear 7 drives the linkage spur gear 11 to rotate exactly one rotation, ensuring the coordinated operation of the feeding, shaping, and cutting processes, thus achieving continuous and automated diaper production.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
