The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0031] like Figures 1 to 7 As shown, a fully automatic plastic hot-melt extrusion molding production system includes a base 1, on which a feeding component 2 and a hot-melt component 3 are arranged on the feeding component 2, the hot-melt component 3 includes a hot-melt channel 31, a rotating component 4 and a winding component 5 driven by the rotating component 4 are arranged on one side of the hot-melt channel 31, the winding component 5 includes a plurality of die heads 51, a calendering component 6 is arranged below the die head 51, a cooling component 7 is arranged on one side of the calendering component 6, and a crushing component 8 is arranged on one side of the cooling component 7, the feeding component 2 is used to transport the raw material into the hot-melt component 3, the hot-melt component 3 is used to hot-melt the raw material in the hot-melt channel 31, the winding component 5 is used to rotate the rotating component 4 to drive the die head 51 to rotate while allowing the raw materials in different areas of the hot-melt channel 31 to be extruded and dropped through the die head 51 and entangled with each other, the calendering component 6 is used to calender the raw material, the cooling component 7 is used to cool the calendered raw material, and the crushing component 8 is used to slice the cooled raw material.

[0032] like Figure 1 As shown, the feeding assembly 2 includes a support plate 21 fixedly mounted on the base 1, and a hopper 22 fixedly mounted on the support plate 21. An auger is arranged in the hopper 22, wherein the auger is connected to a driving device, which can drive the auger to rotate and transport the raw materials. When in use, the mixed raw materials are put into the hopper 22, and the raw materials are transported to the hot melt channel 31 through the auger.

[0033] like Figures 1 to 3As shown, the hot melt assembly 3 also includes heating tubes 32 arranged on both sides of the hot melt channel 31, the hot melt channel 31 is connected to the hopper 22 and an auger is arranged in the hot melt channel 31, wherein the auger is connected to a driving device, which can drive the auger to rotate to transport the raw materials. During the transportation process, the raw materials are hot-melted through the heating tubes 32 and then flow out through the die head 51.

[0034] like Figure 2 and Figure 5 As shown, the rotating assembly 4 includes a motor 41 fixedly arranged on one side of the hot melt channel 31 and a gear 42 fixedly arranged on the output shaft of the motor 41. When in use, when the hot-melted raw material flows out, the motor 41 drives the gear 42 to rotate, thereby driving the die head 51 to rotate.

[0035] like Figures 3 to 7 As shown, the winding assembly 5 also includes a plurality of discharge pipes 52 fixedly arranged on the hot melt channel 31, a fixed disk 53 fixedly arranged below the discharge pipe 52, a rotating disk 54 rotatably arranged on the fixed disk 53, and a gear ring 55 fixedly arranged on the rotating disk 54. The gear 42 is meshed with the gear ring 55, and the die head 51 is tilted and fixedly arranged on the rotating disk 54. The fixed disk 53 and the rotating disk 54 are set as a hollow structure. When the raw material in the hot melt channel 31 is hot-melted, there will be differences in the material ratio of each area up, down, left and right, resulting in uneven material ratio of the raw material after the final calendering, which reduces the product performance. Therefore, when The hot-melted raw materials flow from the four upper, lower, left and right discharge pipes 52 to the fixed disk 53 and the rotating disk 54 respectively, and flow out from the die head 51 while the motor 41 drives the gear 42 to rotate, the gear 42 drives the gear ring 55 to rotate, and the gear ring 55 drives the die head 51 to rotate. When the die head 51 rotates at an uninterrupted uniform speed, the raw materials are entangled with each other in the process of rotating and falling. This setting method allows the raw materials in each area to be extruded from different positions and entangled with each other in the process of falling under the action of rotation. In this way, the raw materials falling on the upper calendering roller 63 and the lower calendering roller 64 can be more evenly proportioned, and the proportion of the calendered sheet can be more even, thereby improving the performance of the product.

[0036] like Figure 6As shown, the calendering assembly 6 includes a conveyor belt 61 fixedly arranged on one side of the base 1, a fixed frame 62 fixedly arranged on the conveyor belt 61, an upper calendering roller 63 and a lower calendering roller 64 rotatably arranged in the fixed frame 62, and the diameter of the lower calendering roller 64 is larger than the diameter of the upper calendering roller 63, wherein the upper calendering roller 63 and the lower calendering roller 64 are both connected with gears, and the two gears are meshed with each other, and the upper calendering roller 63 is connected with a driving device, and the upper calendering roller 63 and the lower calendering roller 64 can be driven to perform relative calendering through the two gears. As for rotation, the conveyor belt 61 is a metal plate chain conveyor belt. When in use, when the raw material falls onto the upper calendering roller 63 and the lower calendering roller 64, the upper calendering roller 63 and the lower calendering roller 64 rotate relatively to calender the raw material, so that the raw material is calendered into a thin sheet and transferred to the conveyor belt 61 for transportation. By staggering the upper and lower parts and making the diameter of the lower calendering roller 64 larger than the diameter of the upper calendering roller 63, the raw material is always located between the upper calendering roller 63 and the lower calendering roller 64 after falling, so as to prevent the raw material from overflowing and falling.

[0037] like Figure 6 As shown, the cooling assembly 7 includes a cooling hood 71 fixedly mounted on the conveyor belt 61 and a fan 72 fixedly mounted on the cooling hood 71. When in use, when the calendered sheet-like raw material is conveyed on the conveyor belt 61, the fan 72 blows air inside the cooling hood 71 to cool the raw material and solidify it.

[0038] like Figure 6 and Figure 7 As shown, the crushing assembly 8 includes a crushing roller 81 rotatably arranged on one side of the conveyor belt 61, and a crushing block 82 fixedly arranged on the crushing roller 81, wherein the two crushing rollers 81 are respectively provided with gears and mesh with each other, and one of the crushing rollers 81 is connected to a driving device, which drives the two crushing rollers 81 to rotate relative to each other. When in use, the two crushing rollers 81 rotate relative to each other, and when the solidified raw material passes between the two crushing rollers 81, the crushing rollers 81 crush and slice the raw material.

[0039] like Figure 1 As shown, a collecting vehicle 9 is also provided below the crushing roller 81 to collect the sliced ​​raw materials.

[0040] Working process

[0041] The mixed raw materials are put into the hopper 22, and the raw materials are transported to the hot melt channel 31 by the auger. During the transportation process, the raw materials are hot-melted by the heating tube 32. The hot-melted raw materials flow from the four upper, lower, left and right discharge pipes 52 to the fixed disk 53 and the rotating disk 54 respectively, and flow out from the die head 51. At the same time, the motor 41 drives the gear 42 to rotate, the gear 42 drives the gear ring 55 to rotate, and the gear ring 55 drives the die head 51 to rotate. When the die head 51 rotates at a constant speed without interruption, the raw materials are entangled with each other during the process of rotation and falling. This setting method makes the raw materials in each area entangled with each other during the falling process under the action of rotation after being extruded from different positions, so that the raw materials falling to the upper calender can be The raw material ratio on the roller 63 and the lower calendering roller 64 is more uniform, and the ratio of the calendered sheet is more uniform, which improves the performance of the product. When the raw material falls onto the upper calendering roller 63 and the lower calendering roller 64, the upper calendering roller 63 and the lower calendering roller 64 rotate relatively to calender the raw material, so that the raw material is calendered into a thin sheet and transferred to the conveyor belt 61 for transportation. When the calendered thin sheet raw material is transported on the conveyor belt 61, the fan 72 blows air in the cooling hood 71 to cool the raw material and solidify the raw material. When the solidified raw material passes between the two crushing rollers 81, the crushing roller 81 crushes and slices the raw material, and then the sliced ​​raw material is collected by the collecting vehicle 9.
