Description

Technical Field

[0001] This utility model relates to the field of composite PVC board raw material processing technology, specifically a raw material fully fusion and mixing mechanism based on composite PVC board. Background Technology

[0002] In the production process of composite PVC board raw materials, a corresponding melting and stirring mechanism is required. Referring to the authorization announcement number CN211518115U, a settling tank for facilitating PVC melting includes a main body, a feed funnel connected through one side of the upper end of the main body, a discharge pipe connected through the lower end of the main body, a motor installed in the middle of the upper end of the main body, and a rotating rod rotatably connected to the lower end of the motor. This avoids the situation where the existing PVC raw materials are relatively viscous and require a lot of time to stir, thus improving the stirring efficiency of existing PVC raw materials. As described in the above patent, most existing raw material melting and stirring mechanisms based on composite PVC boards do not perform vacuum treatment inside the processing end before use. This can easily cause impurities such as air bubbles to be mixed in the raw materials during the subsequent melting process. After the device finishes processing and discharges the molten material, it is difficult to clean the processing end and stirring end of the device in time, which affects subsequent processing steps.

[0014] Beneficial effects

[0015] This invention provides a raw material mixing mechanism based on composite PVC board. Compared with the prior art, it has the following advantages:

[0016] 1. The raw material mixing mechanism based on composite PVC board fully integrates the raw materials. By setting an adjustment component in the device, the vacuum pump works in conjunction with the three-way valve and the connecting plate to vacuum the shell after the raw materials are filled and sealed. This prevents the product from being mixed with impurities such as air bubbles during the subsequent melting and mixing of the raw materials due to excessive air in the shell, which would affect the quality of the finished product. After the molten material is discharged and the device has cooled down, the three-way valve is reversed and the water pump is turned on. The water pump draws water from the external water source and uses the three-way valve and the connecting plate to rinse the inner wall of the shell and the surface of the mixing frame. This improves the cleaning efficiency of the internal processing end and mixing end of the device and reduces the number of subsequent cleaning steps.

[0017] 2. This raw material mixing mechanism based on composite PVC board fully integrates the materials. By setting up a feeding component and a guide component inside the device, after the molten material is mixed and stirred, the angle of the mixing frame is finely adjusted so that the mixing frame drives the cross shaft to coincide with the first cross groove in the sleeve. The electric push rod drives the extension rod and the cross shaft to move down. After the cross shaft is inserted into the first cross groove in the sleeve, the horizontal position of the baffle is adjusted by the hydraulic cylinder assembly, so that the bottom of the shell is connected to the inside of the receiving shell. The motor drives the cross shaft, extension rod, sleeve and auger to rotate through the bevel gear assembly and the mixing frame. The rotating auger guides the molten material falling into the receiving shell to the external raw material recovery end through the receiving shell and the discharge pipe. This setting facilitates the discharge of molten material through the discharge end, avoids blockage, and reduces friction between the auger drive end and the barrier end, thus extending the service life of the device.

The upper end of the sleeve 54 is rotatably connected to the inside of the stirring frame 31. A cross shaft 53 is slidably connected to the upper side of the stirring frame 31 near the sleeve 54. An extension rod 52, coaxially fixedly connected to the cross shaft 53, is vertically slidably connected to the middle of the stirring frame 31. An electric push rod 51 is vertically fixedly connected to the outer side of the top of the housing 1. The bottom extension end of the electric push rod 51 is rotatably connected to the inner side of the top of the extension rod 52. A vertically penetrating part, connected to the first cross shaft 53, is provided inside the sleeve 54.

[0030] After the molten material is mixed and stirred, the angle of the stirring frame 31 is finely adjusted so that the stirring frame 31 drives the cross shaft 53 to coincide with the first cross groove in the sleeve 54. The electric push rod 51 drives the extension rod 52 and the cross shaft 53 to move down. When the cross shaft 53 is inserted into the first cross groove in the sleeve 54, the horizontal position of the baffle 43 is adjusted by the hydraulic cylinder assembly 42 so that the bottom of the shell 1 is connected to the inside of the receiving shell 41. The motor 32 drives the cross shaft 53, the extension rod 52, the sleeve 54 and the auger 55 to rotate through the bevel gear assembly 33 and the stirring frame 31. The rotating auger 55 guides the molten material falling into the receiving shell 41 to the external raw material recovery end through the receiving shell 41 and the discharge pipe 45. The first Hall sensor and the second Hall sensor are used to align the cross shaft 53 with the first cross groove in the sleeve 54.

The user then opens the feed valve and feeds a quantity of composite PVC raw material into the housing 1 through the feed valve and feed pipe 2. After the feeding is complete, the feed valve is closed, and the solenoid valve at the vacuum pump 36's extraction end and the vacuum pump 36 are opened. The vacuum pump 36 uses the solenoid valve and three-way valve 35 to perform vacuuming inside the housing 1. After vacuuming is complete, the solenoid valve is closed, and external hot oil is fed into the heating tank inside the jacket of the housing 1 through the liquid inlet pipe. The hot oil is then discharged through the discharge pipe. The hot oil in the heating tank heats the material inside the housing 1 through heat exchange. This is existing technology, therefore the hot oil addition and discharge components and specific heating steps will not be described in detail. Meanwhile, the electric... The machine 32 drives the stirring frame 31 through the bevel gear assembly 33 to stir the heated material in the shell 1, promoting the melting and full mixing of the material. After the material is melted and mixed, the angle of the stirring frame 31 is finely adjusted so that the stirring frame 31 drives the cross shaft 53 to coincide with the first cross groove in the sleeve 54. The motor 32 is turned off and the electric push rod 51 is started. The electric push rod 51 drives the extension rod 52 and the cross shaft 53 to move down. After the cross shaft 53 is inserted into the first cross groove in the sleeve 54, the horizontal position of the baffle 43 is adjusted by the hydraulic cylinder assembly 42 so that the bottom of the shell 1 is connected to the inside of the receiving shell 41. The motor 32 is started again. The stirring frame 31 drives the cross shaft 53, the extension rod 52, the sleeve 54 and the auger 55 to rotate through its internal second cross groove.
