Description

Technical Field

[0001] This utility model relates to the field of shoe upper processing technology, specifically a three-dimensional shaping steam jet device for shoe uppers. Background Technology

[0002] In the field of shoe upper processing and manufacturing, upper shaping is a crucial step affecting the final quality and wearing experience of footwear. As consumers' demands for footwear comfort and aesthetics continue to rise, and as the footwear industry shifts towards a more efficient and precise production model, the drawbacks of traditional upper shaping technologies are becoming increasingly apparent, making it difficult to meet the industry's development needs.

[0003] Traditional shoe upper shaping devices often employ unidirectional steam injection or fixed mold shaping methods. When dealing with complex curved surfaces of shoe uppers (such as the curvature of the toe and the three-dimensional contour of the heel), uneven steam coverage can easily lead to problems such as incomplete shaping in certain areas and poor surface fit. This results in wrinkles and deformation in the finished shoe uppers, affecting wearing comfort and appearance consistency, with a product defect rate consistently remaining at 10%-20%. Furthermore, the shaping and cooling processes are often separate operations, requiring manual transfer of the shoe uppers. This not only increases labor costs but also slows down the production cycle due to time-consuming process connections, making it difficult to adapt to large-scale mass production needs. Therefore, those skilled in the art have provided a three-dimensional shoe upper shaping steam injection device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a steam jetting device for three-dimensional shaping of shoe uppers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A steam jetting device for three-dimensional shaping of shoe uppers includes a main body, a frame, an arc-shaped door, and a worktable. The main body has a shaping chamber and a cooling chamber. A frame is arranged between the shaping chamber and the cooling chamber. A base is fixedly connected to the lower end of the frame, and the base is fixedly connected to the main body. An arc-shaped door is rotatably connected to the outer ring of the frame, and the arc-shaped door is rotatably connected to the base and the main body. A rotary motor is fixedly installed inside the base. A worktable is rotatably connected to the bottom of the frame. The shaft of the rotary motor is fixedly connected to the worktable. A second rotary motor is fixedly installed inside the worktable. A gear is fixedly connected to the shaft of the second rotary motor. Several gears are meshed around the gear. Both gears are rotatably connected to the worktable. A mold is fixedly connected to the upper end of each gear, and the shoe upper can be fitted onto the mold.

[0007] As a further embodiment of this utility model: a second servo motor is fixedly installed on the upper end of the frame, a worm gear is fixedly connected to the power output end of the second servo motor, a worm wheel is meshed on one side of the worm gear, the worm wheel is rotatably connected to the frame, a main gear is fixedly connected to the upper end of the worm wheel, a driven gear is meshed on one side of the main gear, and an internal gear is fixedly connected to the upper end of the arc-shaped door, wherein the driven gear and the internal gear mesh together.

[0008] As a further improvement of this utility model: a sealing door one is provided at the entrance of the shaping chamber, wherein the sealing door one is hinged to the main body of the device, and a sealing door two is provided at the entrance of the cooling chamber, wherein the sealing door two is hinged to the main body of the device, and observation frames and door handles are fixedly installed on both the sealing door one and the sealing door two.

[0009] As a further embodiment of this utility model: a steam generator is fixedly installed on the left side of the main body of the device, and a steam pipe is fixedly connected and connected to one side of the steam generator. The steam pipe is a stainless steel corrugated pipe that can be bent. A mounting base is fixedly installed on the inner wall of the left side of the shaping chamber, and a first servo motor is fixedly installed on one side of the mounting base.

[0010] As a further embodiment of this utility model: the power output end of the first servo motor is fixedly connected to a first rotating shaft, wherein the first rotating shaft is rotatably connected to the mounting base, and an arc-shaped spray head is fixedly connected to the first rotating shaft, wherein the arc-shaped spray head is fixedly connected to and communicates with the steam pipe, a cooler is fixedly installed on the right side of the main body of the device, and an air outlet is provided on one side of the cooler, wherein the air outlet is located in the cooling chamber, and two support blocks are fixedly connected to the upper end of the frame, wherein the worm gear is rotatably connected to the support blocks.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. Three-dimensional spraying for full coverage: The arc-shaped spray head, combined with the multi-angle swing driven by the servo motor and the flexible stainless steel corrugated pipe, achieves full coverage of the complex curved surface of the shoe upper (such as the curvature of the shoe toe) with steam. At the same time, the mold array adopts a gear linkage design, which makes the shoe upper rotate differently during the shaping process, eliminating the spraying blind spots of traditional equipment.

[0013] 2. Quick interchange between shaping and cooling: Starting the second servo motor drives the worm gear to rotate, which in turn drives the worm wheel, which in turn drives the main gear, which in turn drives the driven gear, which in turn drives the internal gear, which in turn drives the arc-shaped door to rotate. The arc-shaped door moves from the right opening of the frame to the left opening of the frame. At this point, the arc-shaped door changes from isolating the cooling chamber to isolating the shaping chamber. The steam in the shaping chamber no longer affects the shoe upper, while the shoe upper can be cooled in the cooling chamber. This reduces the time between processes and improves production efficiency. Attached Figure Description

[0024] The working principle of this utility model is as follows: In use, multiple shoe uppers are first placed on corresponding molds 26. Then, sealing doors 4 and 5 are closed. Steam is then sprayed onto the shoe uppers through steam jet nozzles to shape them. Starting the rotary motor 23 drives gear 24 to rotate, which in turn drives gear 25 to rotate. Gear 25 then drives mold 26 to rotate, which in turn drives the shoe uppers to rotate. This allows adjustment of the shoe upper's direction, enabling shaping of other parts as well. Starting the first servo motor 10 drives the first rotating shaft to rotate, which in turn drives the steam jet nozzles to rotate. This allows adjustment of the steam jet nozzle's tilt angle, achieving three-dimensional dynamic adjustment of the steam jet direction. After one shoe upper is shaped, starting the rotary motor 22 drives the worktable 21 to rotate, which in turn drives the upper... The shoe covers are rotated to allow the shoe uppers to be swapped, thus shaping the other shoe uppers. After all shoe uppers are shaped, the second servo motor 16 is started to drive the worm gear 17 to rotate. The worm gear 17 drives the worm wheel 18 to rotate, which in turn drives the main gear 19 to rotate. The main gear 19 drives the driven gear 20 to rotate, which in turn drives the inner gear 15 to rotate. The inner gear 15 drives the arc-shaped door 14 to rotate. The arc-shaped door 14 moves from the right opening of the frame 27 to the left opening of the frame 27. At this time, the arc-shaped door 14 changes from isolating the cooling chamber 3 to isolating the shaping chamber 2. Thus, the steam in the shaping chamber 2 no longer affects the shoe uppers, and the shoe uppers can wait to cool. Finally, the cold air fan 11 is started, and the air outlet 12 blows cold air into the cooling chamber 3, which can accelerate the cooling speed of the shoe uppers and shorten the time for taking and putting away the shoe uppers.
