[0003] Existing vacuum machines for enhancing leather gloss often require manual work to smooth out wrinkles on the leather surface. The leather is then vacuumed, heated, and polished to enhance its gloss. This manual leather smoothing process is inefficient and can be harmful to the operator's hands.
[0004] Based on this, it is necessary to design a vacuum machine that can smooth leather and improve the brightness of leather. Utility Model Content

The first electric slide rail is slidably connected with a support block, and the support blocks are commonly connected with a placement plate. The placement plate is arranged in the lower inner cavity of the vacuum machine body. The base is provided with a conveying assembly for conveying leather to the placement plate, and the conveying assembly is provided with a smoothing assembly for smoothing the leather on the placement plate.

A slider is slidably connected to the second electric slide rail, the bottom of the slider is connected to the telescopic rod, the bottom of the telescopic rod is connected to the smoothing scraper, and a second spring is arranged between the smoothing scraper and the slider.
[0008] As a further preferred solution, the stroke of the cylinder piston rod is consistent with the length of the second electric slide rail.
[0009] As a further preferred solution, the stroke of the cylinder piston rod is consistent with the width of the placement plate.
[0010] As a further preferred solution, the bottom of the smoothing scraper is arranged as an inclined surface.

The base 1 is symmetrically arranged on the front and back right side of the bottom of the vacuum machine body 2. The first electric slide 4 is symmetrically arranged on both sides of the front and back of the lower cavity of the vacuum machine body 2. The first electric slide 4 is slidably connected with a support block 401, and the support blocks 401 are commonly connected with a placement plate 3. The placement plate 3 is arranged in the lower inner cavity of the vacuum machine body 2. The cross-sectional area of the placement plate 3 is adapted to the cross-sectional area of the lower inner cavity of the vacuum machine body 2. A conveying component for conveying leather to the placement plate 3 is provided on the base 1, and a smoothing component for smoothing the leather on the placement plate 3 is provided on the conveying component.
[0019] like Figure 2 and Figure 3 As shown, the conveying assembly includes a cylinder 6, a support plate 601 and an electric clamp 7. The support plates 601 are symmetrically arranged on the left and right sides of the base 1, and a cylinder 6 is arranged between the two adjacent support plates 601 on the left and right. The cylinder 6 is arranged on the outer side below the vacuum machine body 2. The stroke of the piston rod of the cylinder 6 is consistent with the width value of the placement plate 3. The movable end of the piston rod of the cylinder 6 is connected to the electric clamp 7. The electric clamp 7 includes an upper clamp block and a lower clamp block. The lower clamp block is an L-shaped structure. The upper clamp block and the lower clamp block are slidably connected. The object is placed between the upper clamp block and the lower clamp block. The upper clamp block and the lower clamp block are close to each other to clamp the object. A non-slip pad is provided on the side where the upper clamp block and the lower clamp block are close to each other. The setting of the non-slip pad can not only provide protection for the leather, but also prevent the leather from slipping off the electric clamp.
[0020] like Figure 3 and Figure 4As shown, the smoothing assembly includes a second electric slide rail 5, a guide rod 501, a first spring 502, a slider 504, a second spring 505, a telescopic rod 506 and a smoothing scraper 8. A slide groove 503 is provided on the base 1. The slide groove 503 is parallel to the cylinder 6. The guide rod 501 is slidably connected in the slide groove 503. A second electric slide rail 5 is provided between the upper clamping block of the electric clamp 7 and the guide rod 501. The stroke of the piston rod of the cylinder 6 is consistent with the length of the second electric slide rail 5. The second electric slide rail 5 is slidably connected to the guide rod 501. The guide rod 501 slides through the right end of the second electric slide rail 5. A first spring 502 is provided between the second electric slide rail 5 and the lower end of the guide rod 501. The first spring 502 is a compression spring. The setting of the spring ensures that a certain distance is maintained between the upper clamping block and the lower clamping block of the electric clamp 7, which facilitates the placement of leather. A slider 504 is slidably connected to the second electric slide rail 5, and a telescopic rod 506 is connected to the bottom of the slider 504.
