The indirect blanking assembly 8 can realize indirect addition of materials, and the cooling assembly 9 can realize the circulation of the cooling liquid in the cooling cavity.

[0029] In this embodiment, the cooling assembly 9 includes a transmission bevel gear 91 fixedly mounted on the output shaft of the drive motor 5 and a rotating bevel gear 92 meshing with the rear side of the transmission bevel gear 91. A rotating rod 93 is fixedly mounted at the middle of the rear side of the rotating bevel gear 92, and a reciprocating screw 94 is fixedly sleeved on the outer side of the rotating rod 93. A screw nut 95 is movably mounted on the outer side of the reciprocating screw 94, and a moving plate 96 is fixedly mounted at the middle of the bottom of the screw nut 95. A U-shaped rod 97 is fixedly mounted on the rear side of the moving plate 96 near the bottom. A piston 98 is fixedly mounted on the end of the U-shaped rod 97 away from the moving plate 96. A plug cylinder 99 is slidably sleeved on the outer side of the piston 98. The rear side of the plug cylinder 99 is fixedly extended through to the outer side of the fixed frame 1, which can drive the piston 98 to move back and forth in the plug cylinder 99, thereby realizing the circulation of coolant in the cooling chamber, achieving cooling and temperature reduction of the coating, and preventing clumping.

[0030] Specifically, a conduit is fixedly installed through the top of the plug cylinder 99 near the front side. A one-way valve B is provided on the outside of the conduit, and the end of the conduit away from the plug cylinder 99 is fixedly extended through the inner cavity of the cooling chamber.

[0031] Specifically, an L-shaped plate 931 is movably mounted on the rear end of the rotating rod 93, and the front side of the L-shaped plate 931 is fixedly mounted on the fixed frame 1. A sliding rod 932 is slidably mounted on the L-shaped plate 931 near the top. The front end of the sliding rod 932 is fixedly mounted on the moving plate 96.

[0032] Specifically, a feed pipe 41 is fixedly installed through the bottom of the mixing cylinder 4 near the right side to facilitate the feeding of raw materials.

[0033] In this embodiment: During use, the raw materials to be mixed can be added to the feed hopper 7. After addition, the drive motor 5 can be started. When the drive motor 5 runs, it will drive the rotating shaft and the transmission bevel gear 91 to rotate.

When the movable plate 96 moves back and forth, it drives the piston 98 to move back and forth in the plug cylinder 99 through the U-shaped rod 97. When the piston 98 moves backward in the plug cylinder 99, it draws coolant into the plug cylinder 99 through the suction pipe. When the piston 98 moves forward, it squeezes the drawn coolant into the cooling chamber through the conduit. Because the piston 98 moves back and forth continuously, it continuously draws coolant and delivers it to the cooling chamber. In addition, when a certain amount of coolant remains in the cooling chamber, it can flow back to the coolant tank 10 through the drain pipe. This can realize the circulation of coolant in the cooling chamber and effectively improve the cooling effect of the raw materials.

[0034] Example 2

[0035] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figures 1-2 and Figures 6-8 The indirect feeding assembly 8 includes a transmission rod 81 located on the lower left side of the feed hopper 7 and a driving bevel gear 82 fixedly sleeved on the outside of the transmission rod 81. The top of the driving bevel gear 82 meshes with a driven bevel gear 83, and a transmission shaft is fixedly installed at the middle of the top of the driven bevel gear 83. A limit plate is fixedly installed on the left side of the feed hopper 7 near the bottom. The upper end of the transmission shaft extends movably through to the outside of the limit plate and is fixedly installed on a turntable 84. A fixed shaft 85 is movably installed on the top of the turntable 84 near the right side. A swing plate 86 is fixedly installed on the upper end of the fixed shaft 85. A T-shaped baffle 87 is movably installed on the right side of the swing plate 86. The right side of the T-shaped baffle 87 slides through to the inner cavity of the feed hopper 7 and fits against the inner wall of the inner cavity of the feed hopper 7. This allows the T-shaped baffle 87 to move back and forth in the feed hopper 7, realizing the indirect addition of coating raw materials and effectively improving the cooling effect.

[0036] Specifically, a first single-grooved wheel is fixedly sleeved on the output shaft of the transmission rod 81, and a second single-grooved wheel is provided below the first single-grooved wheel. A belt 811 is sleeved on the outer side of both the first and second single-grooved wheels. The second single-grooved wheel is fixedly sleeved on the outer side of the rotating shaft. The belt 811 can drive the transmission rod 81 to rotate synchronously with the rotating shaft.

[0037] Specifically, guide rods 871 are slidably installed on the left side of the T-shaped baffle plate 87 near the front and rear sides, respectively. The right ends of the guide rods 871 are fixedly installed on the feed hopper 7. A guide block 872 is attached to the top of the T-shaped baffle plate 87 near the left side. The left side of the guide block 872 is fixedly installed on the inner wall of the inner cavity of the feed hopper 7, which serves to position the T-shaped baffle plate 87 when it moves, and also serves to guide the material.

[0038] In this embodiment: when the rotating shaft rotates, it also drives the transmission rod 81 to rotate via the belt 811. When the transmission rod 81 rotates, it drives the driving bevel gear 82 to rotate. When the driving bevel gear 82 rotates, it drives the transmission shaft to rotate via the driven bevel gear 83. When the transmission shaft rotates, it drives the turntable 84 to rotate. When the turntable 84 rotates, it drives the swing plate 86 to swing back and forth via the fixed shaft 85. This causes the T-shaped baffle plate 87 to move back and forth left and right in the feed hopper 7, realizing the indirect addition of raw materials and improving the mixing and cooling effect.

[0039] Working principle: During use, the raw materials to be mixed can be added to the feed hopper 7. After addition, the drive motor 5 will start. The drive motor 5 will drive the rotating shaft and transmission bevel gear 91 to rotate. The rotating shaft will drive the spiral blades 6 to rotate, thus mixing and conveying the added raw materials to the right, and discharging them through the discharge pipe 41. The rotation of the transmission bevel gear 91 will drive the rotating rod 93 to rotate via the rotating bevel gear 92. The rotating rod 93 will drive the reciprocating screw 94 to rotate. The reciprocating screw 94 will drive the screw nut 95 to move back and forth. The movement of the screw nut 95 will also drive the moving plate 96 to move back and forth. The movement of the moving plate 96 will drive the piston 98 to move back and forth in the plug cylinder 99 via the U-shaped rod 97. When the piston 98 moves backward in the plug cylinder 99, it will draw coolant into the plug cylinder 99 through the suction pipe. When piston 98 moves forward, it can squeeze the drawn coolant into the cooling chamber through the conduit. As piston 98 moves back and forth continuously, it will continuously draw coolant and deliver it into the cooling chamber. In addition, when a certain amount of coolant remains in the cooling chamber, it can flow back to the coolant tank 10 through the drain pipe, which can realize the circulation of coolant in the cooling chamber and effectively improve the cooling effect of raw materials. In addition, when the rotating shaft rotates, it will also drive the transmission rod 81 to rotate through the belt 811. When the transmission rod 81 rotates, it will drive the driving bevel gear 82 to rotate. When the driving bevel gear 82 rotates, it will drive the transmission shaft to rotate through the driven bevel gear 83. When the transmission shaft rotates, it will drive the turntable 84 to rotate. When the turntable 84 rotates, it will drive the swing plate 86 to swing back and forth through the fixed shaft 85, which will drive the T-shaped baffle 87 to move back and forth left and right in the feed hopper 7, realizing the indirect addition of raw materials and improving the mixing and cooling effect.
