Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment, and in particular to a hot steam setting machine for shoe uppers. Background Technology

[0002] Due to differences in their lasting methods, shoe uppers experience varying stress points on their leather, making them prone to wrinkles after shaping and lasting. To overcome this wrinkling problem, current technology typically employs a steam shoe upper softening machine. This machine uses steam to soften and relax the shoe upper, making the upper and last more compact and thus eliminating wrinkles.

[0003] Referring to Chinese utility model patent CN 203457892 U, which discloses "a novel steam shoe upper softening machine, including a frame, which includes a cabinet and an operating platform formed on the upper surface of the cabinet. The cabinet is equipped with a water tank, a water pump, and a heating furnace. Multiple steam softening tubes are vertically fixed on the operating platform." Each steam softening tube can soften one shoe upper, and multiple shoe uppers can be steam softened simultaneously, which can effectively improve efficiency. However, this steam softening tube structure has shortcomings. Shoe uppers are usually sewn with leather at the toe and heel. The steam softening tube only has a steam outlet at the top, requiring workers to frequently and manually switch between the toe and heel, which is quite cumbersome. Furthermore, when the toe is just softened, the heel has a long cooling time, resulting in different softening levels between the toe and heel, leading to poor wrinkle removal effect on the shoe upper. Utility Model Content

[0004] This invention provides a hot steam shaping machine for shoe uppers to solve the problems mentioned above, such as the inconvenience of frequent manual switching, inconsistent softening levels, and poor wrinkle removal effect.

[0005] The present invention adopts the following technical solution: A hot steam setting machine for shoe uppers includes a frame with an operating platform on its upper surface. A water tank, a water pump, and a heating furnace are installed inside the frame. The water tank is connected to the heating furnace via the water pump. The steam outlet of the heating furnace is connected to a gas supply pipe with multiple gas supply branches. The machine also includes a steam softening component, which consists of a first insert and a second insert sleeved on the outside of the first insert. The outer wall of the second insert has multiple external steam holes arranged in a forward spiral, and the outer wall of the first insert has multiple internal steam holes arranged in a reverse spiral, with the internal steam holes corresponding to the external steam holes at the same height. The second insert is fixed to the operating platform, and the first insert is rotatably sleeved on the steam outlet end of the gas supply branch. A small motor for driving the rotation of the first insert is installed inside the frame.

[0006] Furthermore, the inner steam hole and the outer steam hole have the same diameter, which is 2-3 mm, with a preferred diameter of 3 mm.

[0007] Furthermore, the aforementioned gas transmission branch pipe is equipped with a valve, and the aforementioned operating platform is equipped with a valve control knob.

[0008] Furthermore, the lower end of the first insertion tube is provided with a gear, and the small motor is connected to the gear via a chain.

[0009] Furthermore, the aforementioned rack is equipped with a temporary placement platform for placing the soft shoe uppers to be steamed.

[0010] Furthermore, a control panel is provided on the front side wall of the aforementioned rack.

[0011] Furthermore, an inspection port is provided on the left side wall of the aforementioned frame, and a door panel can be detachably installed on the inspection port.

[0012] Furthermore, the four corners of the aforementioned frame are equipped with supports.

[0013] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: 1. The second insertion tube of this application is sleeved on the outside of the first insertion tube. The outer wall of the second insertion tube is provided with a plurality of external steam holes distributed in a positive spiral, and the outer wall of the first insertion tube is provided with a plurality of internal steam holes distributed in a negative spiral. The internal steam holes correspond to the external steam holes at the same height. The motor drives the first insertion tube to rotate, causing the second insertion tube to automatically alternately release steam up and down. This eliminates the need for workers to frequently switch between the shoe toe and the shoe heel, reduces manual intervention steps, lowers operational complexity, and improves work efficiency.

[0014] 2. The first and second inserts of this application work together to allow the leather at the toe and heel to be heated and softened properly, reducing the difference in the degree of softening between the two, making the upper and the last fit more tightly, significantly enhancing the wrinkle removal effect and improving the shaping quality of the upper.

[0015] 3. Based on optimized operation and effect, this application maintains the ability to simultaneously steam and soften multiple shoe uppers, making efficient use of equipment resources, helping enterprises to steadily improve production efficiency and reduce time and labor costs.

[0020] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0021] Reference Figures 1-4 A hot steam setting machine for shoe uppers includes a frame 1 with an operating platform 11 on its upper surface. The frame 1 contains a water tank 5, a water pump 5, and a heating furnace (not shown in the figure). The water tank 5 is used to store water and is connected to the heating furnace through the water pump 5. Specifically, the outlet of the water tank 5 is connected to the inlet of the water pump 5, and the outlet of the water pump 5 is connected to the inlet of the heating furnace. The steam outlet of the heating furnace is connected to a gas supply pipe 31, which has multiple gas supply branch pipes 32. It also includes a steam softening component, which consists of a first insert pipe 2 and a second insert pipe 10 sleeved on the outside of the first insert pipe 2. The outer wall of the second insert pipe 10 has multiple external steam holes 101 arranged in a positive spiral, and the outer wall of the first insert pipe 2 has multiple internal steam holes 20 arranged in a negative spiral. The internal steam holes 20 correspond to the external steam holes 101 at the same height. That is, the internal steam holes 20 at the same height can rotate with the first insert pipe 2 to align with the external steam holes 101. At this time, steam is discharged to the outside from the internal steam holes 20 and external steam holes 101 that are aligned with each other. The remaining internal steam holes 20 are not aligned with the external steam holes 101, that is, no steam is discharged. The second insert pipe 10 is fixed to the above-mentioned operating platform 11. The first insert pipe 2 can be rotatably sleeved on the steam outlet end of the gas supply branch pipe 32. A small motor 4 for driving the rotation of the first insert pipe 2 is installed in the frame 1.

The control knob 12 can control the gas supply branch pipe 32 to be closed or opened respectively, adapting to different working needs, saving energy, and with a reasonable structural design.

[0024] The lower end of the first insertion tube 2 is provided with a gear 21. The small motor 4 is synchronously connected to the gears 21 of all the first insertion tubes 2 through a chain, and automatically moves up and down to move the steam direction.

[0025] Reference Figure 1 The frame 1 is provided with a temporary platform 15 for placing the soft shoe uppers to be steamed. The soft shoe uppers to be steamed are placed on the temporary platform 15 for easy access by workers.

[0026] The front side wall of the frame 1 is equipped with a control panel 14, which is used to send commands to the small motor 4, water pump 5 and heating furnace.

[0027] An inspection port is provided on the left side wall of the frame 1, and a door panel 13 can be detachably installed on the inspection port for convenient maintenance and inspection of internal parts.

[0028] The frame 1 is equipped with brackets 16 at each of its four corners.

[0029] The above are merely specific embodiments of this utility model, but the design concept of this utility model is not limited thereto.
