Detailed Implementation

[0031] The present invention will be further described in detail below with reference to the accompanying drawings.

[0032] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0033] Example: Figures 1-9 As shown, an asphalt mixture precast block production line includes a frame 1, a chassis 2 mounted in the middle of the frame 1, and a rotating disk 3 mounted on top of the chassis 2. The rotating disk 3 is rotatably mounted on the chassis 2. A drive mechanism 5 is mounted at the bottom of the rotating disk 3 for driving the rotating disk 3 to rotate intermittently.

[0034] like Figure 3 As shown, the drive mechanism 5 includes a gear ring 501, a straight rack 502 that meshes with the gear ring 501, a first drive element 503 that pushes the straight rack 502 to move, and a control mechanism that drives the straight rack 502 to mesh or separate from the gear ring 501. The gear ring 501 is fixed to the bottom of the rotating disk 3 and is coaxially arranged with the rotating disk 3.

[0035] The control mechanism includes a drive base 505, a mounting plate 506 mounted on the drive base 505 via a rotating shaft 507, and a second drive element 508 connected between the mounting plate 506 and the drive base 505. A movable seat 504 is provided on the mounting plate 506, a rack 502 is fixed on the movable seat 504, and the second drive element 508 is connected between the movable seat 504 and the mounting plate 506.

[0036] When the rotary disk 3 needs to be rotated, the rack 502 approaches and meshes with the gear ring 501. Then, the first drive element 503 pushes the rack 502 forward a set distance, causing the gear ring 501 to rotate clockwise one position. After the rack 502 stops, the second drive element 508 drives the mounting plate 506 to move outward, causing the rack 502 to separate from the gear ring 501. Then, the first drive element 503 resets and drives the rack 502 to move backward to the initial position, waiting for the next rotation of the rotary disk 3.

[0037] The first driving element 503 and the second driving element 508 can be either a pneumatic cylinder or a hydraulic cylinder.

[0038] Multiple forming molds 4 are distributed around the circumference of the rotating disk 3. Each forming mold 4 has a mold cavity 401, which is hexagonal in shape.

[0039] Along the circumference of the rotating disk 3, the frame 1 is provided with a mold cleaning device 6, a mold spraying device 7, a mixing and feeding device 8, an extrusion molding device 9, and a material taking device 10. Below the material taking device 10, there is a demolding device 11 for ejecting the preform from the molding mold 4.

[0040] like Figure 4 As shown, the mold cleaning device 6 is used to clean the mold cavity 401 of the forming mold 4. The mold cleaning device 6 includes a vertically arranged cleaning spindle 601, a cleaning head 602 arranged at the lower end of the cleaning spindle 601, a first drive motor 603 arranged at the upper end of the cleaning spindle 601 and driving the cleaning spindle 601 to rotate, a first lifting mechanism 605 that drives the cleaning spindle 601 to rise and fall, and a first cross translation mechanism 604 that drives the cleaning spindle 601 to move.

[0041] When the molding die 4 rotates to the position below the mold cleaning device 6, the first lifting mechanism 605 drives the cleaning spindle 601 and the cleaning head 602 to extend into the mold cavity 401 of the molding die 4 and move up and down. The first drive motor 603 drives the cleaning spindle 601 and the cleaning head 602 to rotate. At the same time, the first cross translation mechanism 604 drives the cleaning spindle 601 and the cleaning head 602 to move along the shape of the mold cavity 401 in a hexagonal path, thereby cleaning the inner wall of the mold cavity 401.

[0042] The first cross translation mechanism 604 is existing technology, including a transverse track 6041 installed on the frame 1, a transverse moving seat 6042 that moves along the transverse track 6041, a longitudinal track 6043 set on the transverse moving seat 6042, and a longitudinal moving seat 6044 that moves along the longitudinal track 6043. The movement of the transverse moving seat 6042 and the longitudinal moving seat 6044 is driven by a screw mechanism composed of a motor, a lead screw, and a lead screw nut.

[0043] The first lifting mechanism 605 consists of a first lifting seat 6051 and a first cylinder 6052. The first lifting seat 6051 is slidably mounted on a longitudinal moving seat 6044, and the first cylinder 6052 is connected between the first lifting seat 6051 and the longitudinal moving seat 6044. In this application, the cleaning spindle 601 is rotatably mounted on the first lifting seat 6051, and the first drive motor 603 is mounted on the longitudinal moving seat 6044. A bushing 606 is mounted on the upper end of the cleaning spindle 601, and a splined shaft 607 is installed inside the bushing 606. The bushing 606 can move axially relative to the splined shaft 607, and the splined shaft 607 is connected to the first drive motor 603.

[0044] like Figure 5 As shown, the mold spraying device 7 includes a mounting rod 701, an oil spray head 702 disposed at the lower end of the mounting rod 701, and a second cross translation mechanism 703 disposed at the upper end of the mounting rod 701 and driving the mounting rod 701 to move. The oil spray head 702 is connected to an oil pump through an oil pipe to spray the release agent into the molding mold 4. The structure of the second cross translation mechanism 703 is the same as that of the first cross translation mechanism 604, and will not be described again here.

[0045] like Figure 6 As shown, the mixing and feeding device 8 includes a mixing tank 801 positioned above the rotating disk 3, a mixing main shaft 802 disposed within the mixing tank 801, a second drive motor 804 driving the mixing main shaft 802 to rotate, and mixing blades 803 circumferentially distributed on the mixing main shaft 802. The bottom of the mixing tank 801 has a discharge port 805 corresponding to the lower forming mold 4. The bottom of the mixing tank 801 is in contact with the surface of the rotating disk 3 to prevent material leakage before the forming mold 4 reaches its position. When the forming mold 4 rotates to below the discharge port 805, the mixing main shaft 802 drives the mixing blades 803 to mix, allowing the material to enter the forming mold 4 through the discharge port 805.

[0046] like Figure 7 As shown, the extrusion molding device 9 includes an extrusion die 901 and a hydraulic cylinder 902 that drives the extrusion die 901 to move up and down. The shape of the extrusion die 901 matches the cavity 401 of the molding die 4, and the hydraulic cylinder 902 is fixed to the top of the frame 1.

[0047] After the molding die 4 is filled with material, it is rotated to the bottom of the extrusion molding device 9. The hydraulic cylinder 902 pushes the extrusion die 901 down into the molding die 4 to extrude the material and form a preform.

[0048] like Figure 8 and Figure 9 As shown, the material handling device 10 includes a pneumatic gripper 1001, a second lifting mechanism 1002 for driving the pneumatic gripper 1001 to rise and fall, and a moving mechanism 1003 for driving the pneumatic gripper 1001 to move. The second lifting mechanism 1002 consists of a second lifting seat and a second cylinder. The pneumatic gripper 1001 is mounted on the second lifting seat and uses a three-jaw cylinder, with a clamping plate mounted on each jaw. The moving mechanism 1003 includes a translation rail mounted on a frame, a translation seat that moves along the translation rail, and a lead screw mechanism. The lead screw mechanism consists of a motor, a lead screw, and a lead screw nut.

[0049] The demolding device 11 includes a top block 1101, a third driving element 1102 for driving the top block 1101 to rise and fall, and an ejection assembly disposed above the top block 1101. The ejection assembly includes a support plate 1103 movably disposed within the mold cavity 401 of the molding die 4, a top plate 1105 disposed below the molding die 4, and a support rod 1104 connecting the top plate 1105 and the support plate 1103. The third driving element 1102 can be a cylinder or a hydraulic cylinder.

[0050] After the preform is pressed and formed, the molding mold 4 rotates to the bottom of the material handling device 10. At this time, the demolding device 11 operates, the top block 1101 rises and lifts the top plate 1105, and the support plate 1103 located in the molding mold 4 lifts the preform to the top of the molding mold 4. Then, the second lifting mechanism 1002 drives the pneumatic gripper 1001 to descend. After the pneumatic gripper 1001 clamps the preform, it moves to one side for collection through the moving mechanism 1003.
