Description

Technical Field

[0001] This utility model relates to the field of synthetic leather processing technology, and in particular to a foaming device for synthetic leather production. Background Technology

[0002] In the production of synthetic leather (artificial leather), the foaming process is one of the key steps, directly affecting the product's softness, elasticity, feel, and physical properties. Traditional synthetic leather foaming methods mainly include mechanical foaming, which typically uses high-speed stirring or high-pressure gas injection to disperse the foaming agent in the resin slurry, forming a microporous structure. However, the following problems exist in the foaming process:

[0003] 1. Uneven distribution of air bubbles can easily lead to large air bubbles or foam rupture, affecting product quality.

[0004] 2. Gas injection methods usually rely on external gas sources (such as air compressors), which consumes a lot of energy and has insufficient gas flow control. Utility Model Content

[0005] The purpose of this invention is to provide a foaming device for synthetic leather production, which can improve the dispersion and stability of bubbles, improve product quality, and at the same time reduce energy consumption and dependence on external air sources.

[0006] To achieve the above objectives, a foaming device for synthetic leather production is provided, comprising a base, a mixing tank fixedly connected to the upper outer surface of the base, a mixing mechanism provided on the upper surface of the mixing tank, an annular hollow frame fixedly installed at the bottom of the mixing tank, and a plurality of one-way air valves fixedly connected to the inner and upper surfaces of the annular hollow frame.

A connecting rod is provided inside the fixed column. A piston plate is fixedly connected to the lower end of the connecting rod. Exhaust ports and air inlets are provided on the lower left and right sides of the fixed column. One-way valves are provided on the inner surfaces of the air inlets and exhaust ports.

[0008] According to the foaming device for synthetic leather production, the stirring mechanism includes a first drive motor fixedly connected to the upper surface of the stirring tank. The output end of the first drive motor rotates through the inner surface of the stirring tank and is fixedly connected to a rotating shaft. The first drive motor can drive the stirring shaft and stirring rod to rotate, thereby mechanically stirring the foaming agent solution.

[0009] According to the foaming device for synthetic leather production, a first stirring rod is fixedly connected to the lower outer surface of the rotating shaft, and a second stirring rod located above the first stirring rod is also fixedly connected to the outer surface of the rotating shaft. The setting of the second stirring rod facilitates further stirring of the rising material and improves the foaming efficiency.

[0010] According to the foaming device for synthetic leather production, a second drive motor is fixedly connected to the front outer surface of the fixed column, and a rotating rod is fixedly connected to the output end of the second drive motor. The rotating rod rotates through the front outer surface of the fixed column and is fixedly connected to a rotating disk.

[0011] According to the foaming device for synthetic leather production, a rotating rod is rotatably connected to the rear outer surface of the rotating disc, and a moving plate is rotatably connected to the other end of the rotating rod. The moving plate is slidably connected to the inner surface of the fixed column and fixedly connected to the upper surface of the connecting rod. The rotating rod and the rotating disc are driven to rotate by a first drive motor, thereby driving the rotating rod to rotate, which in turn drives the moving plate and the connecting rod to move up and down reciprocally, further driving the piston plate to move reciprocally to realize gas injection. Compared with the traditional air compressor air supply method, the energy consumption is lower and the gas flow is more stable and controllable.

[0012] According to the foaming device for synthetic leather production, a fixed frame is fixedly connected to the outer right side of the air inlet, and a filter screen is slidably connected inside the fixed frame. The filter screen facilitates the filtration of the incoming air. At the same time, a handle is fixedly connected to the upper part of the filter screen, which can be disassembled for cleaning or replacement to ensure the purity of the gas and avoid impurities from affecting the foaming quality.

[0013] According to the foaming device for synthetic leather production, a connecting pipe is fixedly connected to the left end of the exhaust port, and the right connecting port of the annular hollow frame extends to the right outer surface of the mixing tank, and the connecting pipe is threadedly connected to the connecting port.

[0014] According to the foaming device for synthetic leather production, the upper part of the mixing tank is provided with an inlet and outlet, and the bottom four corners of the base are provided with support columns.

[0015] This utility model has the following beneficial effects:

[0016] 1. Compared with the existing technology, the gas injection is achieved by setting up a second drive motor, rotating rod, rotating disk, rotating rod, moving plate, connecting rod and piston plate, which reduces energy consumption and dependence on external gas source. At the same time, the one-way valves at the air inlet and outlet ensure unidirectional gas flow and avoid energy loss caused by gas backflow.

[0017] 2. Compared with the existing technology, the design of the first drive motor, rotating shaft, first stirring rod, second stirring rod, annular hollow frame and one-way exhaust valve avoids the problem of bubble aggregation, makes the microbubble distribution more uniform, and improves the dispersion and stability of the bubbles.

A second stirring rod 24 located above the first stirring rod 23 is also fixedly connected to the outer surface of the rotating shaft 22. The second stirring rod 24 facilitates further stirring of the rising material and improves the foaming efficiency. An annular hollow frame 6 is fixedly installed at the bottom of the mixing tank 2. Several one-way air valves 61 are fixedly connected to the inner and upper surfaces of the annular hollow frame 6.

[0028] A foaming mechanism 3 is provided on the upper left side surface of the base 1. The foaming mechanism 3 includes a fixed column 31 fixedly connected to the upper surface of the base 1. A second drive motor 32 is fixedly connected to the front outer surface of the fixed column 31. A rotating rod 33 is fixedly connected to the output end of the second drive motor 32. The rotating rod 33 rotatably passes through the front outer surface of the fixed column 31 and is fixedly connected to a rotating disk 34. A rotating rod 35 is rotatably connected to the rear outer surface of the rotating disk 34. A movable plate 36 is rotatably connected to the other end of the rotating rod 35. The movable plate 36 is slidably connected to... On the inner surface of the fixed column 31, the movable plate 36 is fixedly connected to the upper surface of the connecting rod 37. The lower end of the connecting rod 37 is fixedly connected to the piston plate 38, which is slidably connected to the inner surface of the fixed column 31. The second drive motor 32 drives the rotating rod 33 and the rotating disk 34 to rotate, thereby driving the rotating rod 35 to rotate, which in turn drives the movable plate 36 and the connecting rod 37 to move up and down reciprocally, further driving the piston plate 38 to move reciprocally, thus realizing gas injection. Compared with the traditional air compressor air supply method, the energy consumption is lower and the gas flow is more stable.

[0029] The lower left and right sides of the fixed column 31 have exhaust ports and air inlets 4. The inner surfaces of the air inlets 4 and exhaust ports are equipped with one-way valves. When the piston plate 38 moves upward, the one-way valve at the air inlet 4 opens and the one-way valve at the exhaust port closes, allowing air to enter. When the piston plate 38 moves downward, the one-way valve at the air inlet 4 closes and the one-way valve at the exhaust port opens, allowing air to exit. A fixed frame 7 is fixedly connected to the outer right side of the air inlet 4. A filter screen 8 is slidably connected inside the fixed frame 7.

[0030] Working principle: In operation, this foaming device for synthetic leather production adds foaming solvent to the mixing tank 2 through the inlet / outlet 9. The first drive motor 21 is activated, driving the rotating shaft 22 to rotate, which in turn drives the first stirring rod 23 and the second stirring rod 24 to mechanically stir the foaming solvent. Simultaneously, the second drive motor 32 is activated, driving the rotating rod 33 to rotate, which in turn drives the rotating disc 34 and the rotating rod 35 to rotate, thereby causing the moving plate 36 and the connecting rod 37 to reciprocate up and down. This further drives the piston plate 38 to reciprocate. When the piston plate 38 moves upward, the one-way valve at the air inlet 4 opens, and the one-way valve at the exhaust port closes. When the piston plate 38 moves downward, the one-way valve at the air inlet 4 closes, and the one-way valve at the exhaust port opens, thus injecting air into the mixing tank 2 through several one-way exhaust valves 61, achieving the foaming operation. The foamed material is finally output from the inlet / outlet 9.
