Description

Technical Field

[0001] The utility model relates to a vacuum machine, in particular to a vacuum machine for improving the flatness of leather. Background Art

[0002] In the leather manufacturing industry, during the leather-making process, it is necessary to reduce the moisture content of the leather after wet processing. Processing is completed through equipment, but during the processing, the leather is prone to wrinkles and unevenness due to uneven evaporation of moisture. A vacuum machine is used to dry the leather.

[0003] To solve this problem, most processing plants use a vacuum machine. By combining the action of vacuum pressure and heating, the uniform evaporation of moisture inside the leather is promoted to achieve a flat effect. However, in the existing vacuum machines, when drying the leather, for clamping and fixing the leather, it is completed through a clamping component. The clamping component is generally connected to a spring, and the two ends of the leather are clamped by the elastic force of the spring. This clamping method has insufficient stability. When drying the leather, due to the loss of moisture, the shape of the leather will change slightly. If the clamping component is not stable enough, wrinkles will appear on the surface of the leather, and it is difficult for the leather to maintain a straight state for a long time, which will affect the flatness of the leather.

[0004] Based on this, to solve the technical defect that the existing vacuum machine affects the flatness of the leather due to insufficient stability when clamping the leather, a vacuum machine for improving the flatness of leather is proposed. Summary of the Utility Model

[0005] In order to overcome the above-mentioned drawbacks, the technical problem of the utility model is: to provide a vacuum machine for improving the flatness of leather.

[0006] The technical implementation solution of the utility model is: a vacuum machine for improving the flatness of leather, which includes a vacuum machine, a machine cover, a rotating shaft, a vacuum pump, a rotating bracket, a connecting shaft, a bottom plate, a moving plate I, a moving plate II, a fixed clamp, an adjusting component, and a power component. The front side of the upper part of the vacuum machine is rotatably connected with a rotating shaft, and the machine cover is connected to the rotating shaft. The machine cover is clamped to the front side of the vacuum machine. The left side of the vacuum machine is connected with a vacuum pump, and the connecting pipe of the vacuum pump is connected to and communicated with the vacuum machine. The inner side walls of both sides in the vacuum machine are rotatably connected with connecting shafts, and rotating brackets are connected to the inner sides of the connecting shafts. The rotating brackets are triangular structures. Three bottom plates are connected between the two rotating brackets, and the three bottom plates are distributed in a three-dimensional triangular structure. The moving plate I is slidably connected to the bottom plates symmetrically from left to right, the moving plate II is slidably connected to both sides of the moving plate I, and the fixed clamp is connected to the moving plate II. A power component is arranged on the vacuum machine, and an adjusting component is arranged on the bottom plate.

[0007] Furthermore, the adjustment assembly includes a bidirectional lead screw I, a guide rod I, a bidirectional lead screw II, and a guide rod II. A bidirectional lead screw I is rotatably connected to one side of the bottom plate, and a guide rod I is connected to the other side of the bottom plate. The moving plate I is threadedly connected to the bidirectional lead screw I on the same side and slidably connected to the guide rod I on the same side. A bidirectional lead screw II is rotatably connected to one side inside the moving plate I, and a guide rod II is connected to the other side inside the moving plate I. The moving plate II is threadedly connected to the bidirectional lead screw II on the same side and slidably connected to the guide rod II on the same side.

[0008] Furthermore, the power assembly includes a driving motor I and a driving motor II. A driving motor I is installed on the left side of the vacuum machine, and the output shaft of the driving motor I penetrates the inside of the vacuum machine and is connected to the connecting shaft on the left side. Driving motors II are installed on the right side of the bottom plate, and the output shafts of the driving motors II are connected to the bidirectional lead screws I on the same side.

[0009] Furthermore, it further includes a knob, and knobs are connected to the right sides of the bidirectional lead screws II.

[0010] Furthermore, it further includes feet, and feet for support are symmetrically connected to the bottom of the vacuum machine.

[0012] Furthermore, it further includes a handle, and a handle is connected to the lower side of the machine cover.

[0013] Furthermore, an anti-rust layer is coated on the outer surfaces of the bidirectional lead screw I and the bidirectional lead screw II.

[0014] Furthermore, the fixing clip is a spring clip, and a torsion spring is provided inside for connection.

[0015] Furthermore, the material of the bottom plate is titanium alloy.

[0016] The utility model has the following advantages: 1. The position of the fixing clip needs to be adjusted by moving the moving plate I and the moving plate II. When the bidirectional lead screw I and the bidirectional lead screw II are in a static state, they will not easily rotate, ensuring the stability of the fixing clip. After the fixing clip fixes both ends of the leather, the leather can be tightened and is not prone to loosening, which can improve the flatness of the leather;

[0017] 2. The adjustable setting of the fixing clip can be applied to leathers of different lengths and widths, with better practicability.

[0025] Embodiment: A vacuum machine for improving the flatness of leather, as Figures 1 - 5As shown in the figure, it includes a vacuum machine 2, a machine cover 3, a rotating shaft 31, a vacuum pump 4, a rotating bracket 6, a connecting shaft 61, a bottom plate 7, a moving plate I 11, a moving plate II 15, a fixing clip 16, an adjusting component and a power component. The front side of the upper part of the vacuum machine 2 is rotatably connected with a rotating shaft 31, and the machine cover 3 is connected to the rotating shaft 31. The machine cover 3 is clamped to the front side of the vacuum machine 2. The left side of the vacuum machine 2 is connected with a vacuum pump 4 by bolts. The connecting pipe of the vacuum pump 4 is connected and communicated with the vacuum machine 2. On the left and right inner side walls of the vacuum machine 2, there are rotatably connected with connecting shafts 61. The inner sides of the connecting shafts 61 are connected with rotating brackets 6. The rotating brackets 6 are triangular structures. Between the two rotating brackets 6, there are connected with three bottom plates 7. The three bottom plates 7 are distributed in a three-dimensional triangular structure. The material of the bottom plate 7 is titanium alloy, which has high temperature resistance. On the bottom plates 7, there are slidably connected with moving plates I 11 symmetrically left and right. On both sides of the moving plates I 11, there are slidably connected with moving plates II 15. On the moving plates II 15, there are connected with fixing clips 16. The fixing clips 16 are spring clips and are internally provided with a torsion spring connection. There is a power component on the vacuum machine 2 and an adjusting component on the bottom plate 7.

[0026] As Figures 2 - 5 shown, the adjusting component includes a bidirectional lead screw I 9, a guide rod I 10, a bidirectional lead screw II 13 and a guide rod II 14. On one side of the bottom plate 7, there are rotatably connected with bidirectional lead screws I 9. On the other side of the bottom plate 7, there are welded with guide rods I 10. The moving plates I 11 are threadedly connected with the bidirectional lead screws I 9 on the same side. The moving plates I 11 are slidably connected with the guide rods I 10 on the same side. On one inner side of the moving plates I 11, there are rotatably connected with bidirectional lead screws II 13. On the other inner side of the moving plates I 11, there are welded with guide rods II 14. The moving plates II 15 are threadedly connected with the bidirectional lead screws II 13 on the same side. The moving plates II 15 are slidably connected with the guide rods II 14 on the same side. The outer surfaces of the bidirectional lead screw I 9 and the bidirectional lead screw II 13 are coated with an anti-rust layer.

[0027] As Figure 1 、 Figure 2 and Figure 4 shown, the power component includes a driving motor I 5 and a driving motor II 8. The driving motor I 5 is installed on the left side of the vacuum machine 2 by bolts. The output shaft of the driving motor I 5 penetrates through the inside of the vacuum machine 2 and is connected to the connecting shaft 61 on the left side. On the right side of the bottom plate 7, there are installed driving motors II 8 by bolts. The output shafts of the driving motors II 8 are connected to the bidirectional lead screws I 9 on the same side.

[0028] As Figures 1 - 3 and Figure 5 shown, it further includes feet 1, knobs 12, a transparent viewing window 32 and a handle 33. On one side of the bidirectional lead screw II 13, there are welded with knobs 12. On the left and right sides of the bottom of the vacuum machine 2, there are connected with feet 1 for support by bolts. On the machine cover 3, there is welded a transparent viewing window 32. On the lower side of the machine cover 3, there is welded a handle 33.

[0029] When drying leather, first pull the handle 33 to turn the machine cover 3 open. The rotating shaft 31 and the transparent viewing window 32 will rotate accordingly. Then fix the leather on the bottom plate 7, and fix both ends of the leather with the fixing clips 16. Before fixing, the length of the leather can be determined first, and the position of the fixing clip 16 can be adjusted. Starting the driving motor II 8 can drive the bidirectional lead screw I 9 to rotate through the output shaft. The bidirectional lead screw I 9 drives the two moving plates I 11 to move inward, moving along the guide rod I 10. The fixing clip 16 moves horizontally along with the moving plate I 11. Similarly, controlling the driving motor I 5 to rotate in the reverse direction can drive the bidirectional lead screw I 9 to rotate in the reverse direction through the reverse rotation of the output shaft, driving the moving plate I 11 to move outward along the guide rod I 10, and the fixing clip 16 moves accordingly. The horizontal distance between the fixing clips 16 on the left and right sides can be adjusted. After adjustment, turn off the driving motor I 5, and manually rotate the knob 12, which can drive the bidirectional lead screw II 13 to rotate, driving the moving plate II 15 to move longitudinally outward along the guide rod II 14 to adjust the distance. The fixing clip 16 moves along with the moving plate II 15, and can be adjusted according to the width of the leather. Reversing the knob 12 can drive the bidirectional lead screw II 13 to rotate in the reverse direction, and then the moving plate II 15 and the fixing clip 16 move longitudinally inward to adjust. Stop rotating the knob 12 after adjustment. Clamp the leather with the fixing clip 16. The settings of the bidirectional lead screw I 9 and the bidirectional lead screw II 13 can stabilize the moving plate I 11 and the moving plate II 15, enabling the leather to maintain a taut state. When the driving motor I 5 is in the off state, the output shaft is relaxed. There are a total of three bottom plates 7 in the vacuum machine 2, and three pieces of leather can be fixed. By rotating the bottom plate 7, the leather can be fixed one by one, and the driving motor I 5 will not affect the rotation of the bottom plate 7.

[0030] After all the leather is fixed, the machine cover 3 can be reversed and closed, and then the vacuum machine 2, the vacuum pump 4, and the driving motor I 5 are started. The vacuum pump 4 can make the inside of the vacuum machine 2 in a vacuum environment, reducing the oppression of gas molecules on the leather, which is beneficial for the moisture inside the leather to evaporate more easily. The moisture in the leather is evaporated through heating and decompression by the vacuum machine 2, thus achieving drying. The driving motor I 5 operates, and the output shaft rotates to drive the connecting shaft 61 and the rotating bracket 6 to rotate, and then drives the bottom plate 7 to rotate. The bottom plate 7 drives the leather to rotate, and the rotation of the leather can be heated better, improving the drying speed, giving enough time for the vacuum and heat to act evenly on each part of the leather, thus avoiding uneven drying of the leather caused by local drying being too fast or too slow. The torsion spring inside the leather clamp is set and will not easily open. The bidirectional lead screw I 9 and the bidirectional lead screw II 13 fix the moving plate I 11 and the moving plate II 15, which can ensure that the position of the leather clamp will not easily change, ensuring that the leather is in a taut state and improving the flatness during the leather drying process. The setting of the transparent viewing window 32 facilitates the staff to check the drying situation of the leather. After the drying is completed, turn off the power of this device and unload the dried leather.
