Description

Technical Field

[0001] This utility model relates to the field of porous brick production technology, specifically to an extrusion molding device for manufacturing porous bricks. Background Technology

[0002] Porous bricks are a commonly used building material, mainly including sintered porous bricks and concrete porous bricks. Porous bricks are formed by extrusion molding devices.

[0003] For example, Chinese patent CN211762287U describes a perforated brick stamping machine. This machine includes a body, guide wheels, and guide grooves. Guide wheels are rotatably connected to both ends of the body, and the guide wheels are located on both sides within the guide groove cavity. This invention uses a hydraulic telescopic rod to control the lifting and lowering of the stamping device, making it more efficient and labor-saving. While the lifting plate drives the pressing mechanism upwards, a connecting rod pulls the pull ring, simultaneously lifting the lower die groove. This allows for rapid demolding of the pressed perforated bricks, resulting in greater efficiency and labor savings. The upper die is connected to the vibrating plate via a slot and can be fixed by a rotating fixing rod, making installation and disassembly of the upper die more convenient and labor-saving. By replacing the upper die, different perforated bricks can be pressed, making it more flexible in use.

[0004] However, the above-mentioned structure requires separate operation for feeding, forming and unloading, and cannot be operated simultaneously, resulting in low overall efficiency. In addition, there are many structures for forming and feeding / unloading.

[0005] Based on this, the present invention designs an extrusion molding device for manufacturing porous bricks to solve the above problems. Utility Model Content

[0015] Furthermore, when the limiting plate contacts the pressure plate, the bottom of the pressure plate is flush with the top of the rotating assembly.

[0016] Furthermore, when the punch moves to its uppermost position, the bottom of the punch is lower than the top of the second straight hole.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] The present invention will be further described below with reference to the embodiments. Example 1

[0033] Please refer to the instruction manual appendix. Figures 1-7 An extrusion molding apparatus for manufacturing porous bricks includes a base plate 1;

[0034] A column 3 is fixedly connected to each of the four corners of the top of the base plate 1, and a first support plate 2 is fixedly connected to the middle of the column 3;

[0035] A rotating assembly 6 for intermittent, constant-angle rotation is fixedly connected at the top center of the base plate 1;

[0036] The column 3 is movably connected to a forming and discharging assembly 4 for forming and discharging. The forming and discharging assembly 4 includes a reciprocating assembly, a forming assembly, and a pushing assembly. The reciprocating assembly is connected to the rotating assembly 6, and the reciprocating assembly is connected to the forming assembly and the pushing assembly.

[0037] The top of the first support plate 2 is fixedly connected to a support frame 7. The support frame 7 is respectively equipped with a feeding channel 8 for feeding and an anti-overflow cylinder 9 for preventing material overflow. The bottom of the feeding channel 8 is slidably connected to the top of the rotating component 6. The feeding channel 8 is offset from the forming component and the pushing component of the forming and discharging component 4. The anti-overflow cylinder 9 is located directly below the forming component. The first support plate 2 is provided with a feeding hole 11, which is located directly below the pushing component.

[0038] The external driving structure drives the reciprocating component of the forming and discharging component 4 to move up and down. The reciprocating component drives the forming component and the pushing component to move up and down. During the time it takes for the forming component and the pushing component to move from the top of the rotating component 6 to the top of the rotating component 6, the rotating component 6 rotates 90 degrees. The forming component and the pushing component are inside the rotating component 6, and the rotating component 6 does not rotate. This achieves the coordinated driving of the rotating component 6 and the forming and discharging component 4. The power requirement is low, which is convenient for practical applications. The feeding, unloading and forming are carried out simultaneously.

[0039] The reciprocating assembly includes a first crankshaft 41, a movable plate 42, a horizontal support shaft 43, a movable horizontal plate 44, a pulley 45, and a second crankshaft 46. The movable horizontal plate 44 is slidably connected to the column 3 through a linear bearing. The horizontal support shaft 43 is fixedly connected to both the left and right ends of the movable horizontal plate 44. The movable plate 42 is rotatably connected to the horizontal support shaft 43. The lower end of the movable plate 42 is rotatably connected to the first crankshaft 41 and the second crankshaft 46, respectively. The second crankshaft 46 and the first crankshaft 41 are both fixedly connected to the input end of the rotating assembly 6. The pulley 45 is fixedly connected to the outer end of the second crankshaft 46. The forming assembly and the pushing assembly are fixedly connected to the movable horizontal plate 44.

[0040] Pulley 45 is fixedly connected to the output end of an external drive structure via a belt;

[0041] The forming assembly includes a punch 47, a spring 48, a first straight hole 411, a second straight hole 412, a pressure plate 413, and a limiting plate 414. The movable horizontal plate 44 is fixedly connected to the punch 47 in a rectangular array above the overflow cylinder 9. The top of the first support plate 2 has a first straight hole 411 that works with the punch 47. The movable horizontal plate 44 is fixedly connected to the spring 48 above the overflow cylinder 9. The bottom of the spring 48 is fixedly connected to the pressure plate 413. The pressure plate 413 has a second straight hole 412 that slides and fits against the punch 47. The upper end of the inner wall of the overflow cylinder 9 is fixedly connected to the limiting plate 414. The outer wall of the pressure plate 413 slides and fits against the inner wall of the overflow cylinder 9. The outer wall of the pressure plate 413 slides and fits against the rotating assembly 6.

[0042] When the limiting plate 414 contacts the pressure plate 413, the bottom of the pressure plate 413 is flush with the top of the rotating assembly 6;

[0043] When punch 47 moves to its uppermost position, the bottom of punch 47 is lower than the top of the second straight hole 412.

[0044] The feeding assembly includes a straight rod 49 and a push plate 410. The straight rod 49 is fixedly installed at the bottom of the movable horizontal plate 44, and the push plate 410 is fixedly installed at the bottom of the straight rod 49. The feeding hole 11 is located directly below the push plate 410.

[0045] The feeding channel 8, the push plate 410 and the anti-overflow cylinder 9 are located at 0°, 180° and 270° of the circular trajectory of the rotating component 6, respectively.

[0046] The external drive structure drives the pulley 45 of the reciprocating assembly of the forming and discharging component 4 to rotate. The pulley 45 drives the second crankshaft 46 to rotate, which in turn drives the rotating assembly 6 to rotate. The second crankshaft 46 drives the first crankshaft 41 to rotate, and the first and second crankshafts 41 and 46 drive the movable plate 42 to rotate. The movable plate 42 drives the horizontal support shaft 43 to move up and down. Under the action of the column 3, the horizontal support shaft 43 drives the movable horizontal plate 44 to move up and down reciprocally. The movable horizontal plate 44 of the reciprocating assembly drives the straight rod 49 of the forming assembly and the punch 47 and spring 48 of the pushing assembly to move up and down reciprocally. The straight rod 49 drives the push plate 410 to move up and down, and the spring 48 drives the pressure plate 413 to move up and down reciprocally. During the time it takes for the push plate 410 of the forming assembly and the pressure plate 413 of the pushing assembly to move from the top of the rotating assembly 6 to the top of the rotating assembly 6, the rotating assembly 6 rotates 90 degrees. Then the push plate 410 of the forming assembly and the pressure plate 413 of the pushing assembly move up and down. Plate 413 and punch 47 move into rotating assembly 6. Plate 413 moves within rotating assembly 6 to press the material. Punch 47 perforates the pressed material within rotating assembly 6. Waste material is discharged from the first straight hole 411. Simultaneously, push plate 410 pushes the formed porous brick out of rotating assembly 6 and then discharges it from discharge hole 11. When push plate 410 and punch 47 move within rotating assembly 6, rotating assembly 6 does not rotate. This allows rotating assembly 6 to cooperate with forming and discharging assembly 4 for driving, requiring less power and facilitating practical application. Feeding, discharging, and forming are carried out simultaneously. When plate 413 moves upward, limit plate 414 contacts punch 47, which separates from the formed porous brick. This prevents the formed porous brick from moving upward with punch 47, thus controlling the formed porous brick to always be within rotating assembly 6. This also prevents punch 47 from bringing the top of the formed porous brick above the top of rotating assembly 6, ensuring the quality of the formed porous brick.

[0047] The bottom of the first support plate 2 is fixedly connected to a slag discharge channel 10 for waste discharge, and the slag discharge channel 10 is located directly below the first straight hole 411.

[0048] When punch rod 47 is forming a hole, the waste material is discharged through slag discharge channel 10;

[0049] The rotating assembly 6 includes a quarter cam divider 61, a turntable 62, a horizontal shaft 63, and a hopper 64. The quarter cam divider 61 is fixedly installed on the top of the base plate 1. Both ends of the input end of the quarter cam divider 61 are fixedly connected to the horizontal shaft 63. The horizontal shaft 63 is rotatably connected to the first crankshaft 41 and the second crankshaft 46, respectively. The output end of the quarter cam divider 61 is fixedly connected to the turntable 62. The turntable 62 has four sets of hoppers 64 evenly spaced along the circumference. The hoppers 64 pass through the turntable 62.

[0050] When the second crankshaft 46 rotates, it drives the horizontal shaft 63 of the rotating assembly 6 to rotate. The horizontal shaft 63 drives the output end of the quarter cam divider 61 to rotate. The quarter cam divider 61 drives the turntable 62 to rotate. The horizontal shaft 63 drives the hopper 64 to rotate intermittently at equal angles. During the time it takes for the push plate 410 of the forming assembly and the pressure plate 413 of the pushing assembly to move from the top of the rotating assembly 6 to the top of the rotating assembly 6, the rotating assembly 6 rotates 90 degrees. The empty hopper 64 is rotated to the bottom of the feeding channel 8 for feeding. After feeding, the hopper 64 rotates to the bottom of the punch 47. The formed porous brick is rotated to the bottom of the slag discharge channel 10. Then the forming assembly... The push plate 410 of the component and the pressure plate 413 and punch 47 of the feeding assembly move into the rotating assembly 6. The pressure plate 413 moves in the rotating assembly 6 to press the material, and the punch 47 perforates the pressed material in the rotating assembly 6. The waste material is discharged from the first straight hole 411. At the same time, the push plate 410 pushes the formed porous brick out of the rotating assembly 6 and then discharges it from the discharge hole 11. When the push plate 410 and the punch 47 move in the rotating assembly 6, the rotating assembly 6 does not rotate. This realizes the coordinated drive of the rotating assembly 6 and the forming and discharging assembly 4. The power requirement is low, which is convenient for practical application. The feeding, discharging and forming are carried out simultaneously.

[0051] The bottom plate 1 is connected to the top of the discharge assembly 5, and the discharge assembly 5 is connected to the four-part cam divider 61. The discharge assembly 5 is located directly below the discharge hole 11.

[0052] The discharge assembly 5 includes a transmission assembly 51, a second support plate 52, and a conveyor belt 53. The second support plate 52 is fixedly installed on the top of the base plate 1. The second support plate 52 is rotatably connected to the conveyor belt 53, and the conveyor belt 53 is located directly below the discharge hole 11. The conveyor belt 53 is fixedly connected to a set of pulleys of the transmission assembly 51, and the other set of pulleys of the transmission assembly 51 is fixedly connected to a set of horizontal shafts 63.

[0053] When the horizontal shaft 63 rotates, it drives the transmission component 51 of the discharge component 5 to rotate. When the transmission component 51 rotates, the conveyor belt 53 rotates. The push plate 410 pushes the formed porous brick from the discharge hole 11 onto the conveyor belt 53. The conveyor belt 53 transports the formed porous brick to the next process, which is convenient for actual use.
