Description

Technical Field

[0001] This invention belongs to the field of brick-making equipment technology, and in particular relates to a pallet-free brick-making machine. Background Technology

[0002] Brick-making equipment is used to press and shape brick blanks. The unfired bricks produced by this equipment are widely used in various industries. Current brick-making equipment is based on a brick blank pallet. During operation, the brick blank pallet is conveyed to the pressing station by a feeding device. The lower mold rests on the brick blank pallet, and mixed material is injected into the mold cavity of the lower mold. Then, the upper mold descends and closes with the lower mold, simultaneously applying hydraulic pressure and vibration to promote the pressing and shaping of the mixed material within the mold cavity. Therefore, the brick blank is directly pressed and shaped on the pallet, making the pallet an indispensable operating element of this type of brick-making equipment. After forming, the pallet, along with the supported and demolded brick blanks, is discharged from the pressing station and transferred to subsequent processes, ultimately being transported to the curing area using forklifts or other machinery.

[0003] The aforementioned brick-making equipment based on brick blank pallets has the following problems: Since the entire processing involves the cyclical use of pallets, it is necessary to configure a pallet feeding device to place the pallets into the molding station and a pallet recycling device. It also involves the operation of transferring the recycled pallets back to the pallet feeding device. This makes the brick-making equipment more complex in structure and occupies a large area. In addition, it requires the participation of manpower (manual labor and forklifts and other tools), resulting in more labor costs for the brick-making equipment.

[0004] In summary, it is necessary to develop and design a brick-making machine that is no longer based on brick blank pallets in order to solve the aforementioned problems. Summary of the Invention

[0005] The purpose of this invention is to provide a pallet-free brick-making machine that does not rely on pallets for operation, thereby reducing the complexity of the brick-making machine and the area it occupies, while also reducing the labor costs consumed in its operation.

[0010] Preferably, the forming platform includes a bottom crossbeam fixedly connected to the main frame and four top crossbeams fixedly connected to the main frame in the front, rear, left, and right directions.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention provides a pallet-free brick-making machine. Compared with existing pallet-based brick-making machines, this invention's brick-making machine does not rely on brick blank pallets. This brick-making machine is equipped with a movable and shiftable molding assembly and a molding platform is set on one side of the main frame. The molding assembly moves to the molding platform and completes the molding of the brick blank on the platform. Afterwards, the molding assembly returns and shifts to a position away from the molding platform for demolding and unloading. Therefore, this brick-making machine eliminates its dependence on brick blank pallets. Since traditional pallets are no longer used, the brick-making machine no longer requires a pallet feeding device and a pallet recycling device, simplifying the equipment structure and significantly reducing the equipment's footprint, meaning this brick-making machine can be arranged even in limited spaces.

[0016] On the other hand, since no manual intervention is required for the cyclical transfer of pallets, this brick-making machine reduces the labor costs consumed in its operation and lowers production and operating costs. Attached Figure Description

[0026] Please see Figure 1 This invention provides a pallet-free brick-making machine, including a pressing device and a feeding device. The pressing device is used to press the mixed raw material into brick blanks, and the feeding device is used to feed the mixed raw material to the pressing device.

[0027] Please see Figure 4 , Figure 7 and Figure 8 It can be seen that:

[0028] The forming device includes a main frame 1, a forming platform 6 is provided on one side inside the main frame 1, a forming component that reciprocates and moves along the length direction is also installed on the main frame 1, and a traveling drive component 7 is installed between the forming component and the main frame 1. The forming component moves to the forming platform 6 to perform the forming operation, and the forming component moves to a position away from the forming platform 6 to demold and unload the material.

[0029] like Figure 4 As shown, the forming platform 6 is located on the left side of the main frame 1. Therefore, the left side is the forming station, and the right side is the demolding and unloading station. During operation, the forming assembly moves to the left side to complete the pressing and forming of the brick blank on the forming platform 6. Afterward, the forming assembly moves to the right side, that is, to the demolding and unloading station, for demolding and unloading. Figure 1 As shown in the figure, a brick stacking machine can be placed at the position of the dotted cuboid drawn on the right side of the main frame 1. The molding component moves above this brick stacking machine. When demolding and unmolding, the bricks are demolded layer by layer on the brick stacking machine, and the bricks are stacked layer by layer on the brick stacking machine to form a brick stack. Finally, the brick stack is transferred to the curing site using forklifts and other equipment.

[0030] In this embodiment, as Figure 5 and Figure 6 As shown, the forming platform 6 includes a bottom crossbeam 6-1 fixedly connected to the main frame 1 and four top crossbeams 6-2 fixedly connected to the main frame 1 (front, rear, left, and right). Supporting longitudinal beams 6-5 are installed above the bottom crossbeam 6-1 and inside the top crossbeams 6-2. Side baffles 6-3 are installed on each top crossbeam 6-2, forming rectangular spaces between the side baffles 6-3. Flat supports 6-7 with top pads 6-4 are provided between each side baffle 6-3, and rubber blocks 6-6 are provided between the flat supports 6-7 and each supporting longitudinal beam 6-5.

[0031] The pad 6-4 and the flat support 6-7 provide a horizontal platform for the pressing and forming of the brick blank. The purpose of installing the rubber block 6-6 on the flat support 6-7 and the supporting longitudinal beam 6-5 is to provide an elastic buffer effect, avoid the rigid hydraulic pressure of the pressing component above on the pressing platform 6, and avoid damage to the pressing platform 6.

[0032] The forming assembly includes a forming frame 9, with a liftable upper mold assembly 16 located below the forming frame 9, and a liftable lower mold assembly 10 located below the upper mold assembly 16. A forming mechanism for driving the upper mold assembly 16 to move vertically and a demolding mechanism for driving the lower mold assembly 10 to move vertically and vertically are also installed on the forming frame 9.

[0033] In this embodiment, the upper mold assembly 16 of the forming assembly includes an upper lifting platform plate 16-1 and an upper mold 16-2 with multiple pressure heads detachably connected to the upper lifting platform plate 16-1; the lower mold assembly 10 of the forming assembly includes a lower lifting platform plate 10-1 and a lower mold 10-2 with multiple mold cavities detachably connected to the lower lifting platform plate 10-1. When the mold is closed, the upper mold 16-2 descends and its pressure heads enter their respective mold cavities. Under the action of hydraulic pressure, the mixed blanks in the mold cavities are pressed into shape.

[0034] The purpose of detachably connecting the upper lifting platform plate 16-1 to the upper mold 16-2 and the lower lifting platform plate 10-1 to the lower mold 10-2 is to allow the upper mold 16-2 and the lower mold 10-2 to be selected and replaced according to the type of brick blank produced.

[0035] like Figure 7 As shown, an airbag assembly 10-3 is also installed between the lower lifting platform plate 10-1 and the lower mold 10-2. Specifically, the lower lifting platform plate 10-1 has a window in the middle for the lower mold 10-2 to be inserted downwards. The lower part of the lower mold 10-2 is inserted into the aforementioned window. The airbag assembly 10-3 includes a support seat installed on the lower lifting platform plate 10-1 and a pressure plate with a window and a connecting seat in the middle. The support seat passes upwards through the window on the pressure plate and is hinged to the connecting seat. The inner edge of the pressure plate presses against the upper side edge of the lower mold 10-2. An airbag is installed between the outer edge of the pressure plate and the lower lifting platform plate 10-1.

[0036] The aforementioned structure allows the lower mold 10-2 to be detachable and floatingly mounted on the lower lifting platform plate 10-1. When the lower mold 10-2 is lowered onto the pad 6-4 of the forming platform 6, the bottom of the lower mold 10-2 first contacts the pad 6-4 and stops descending. At this time, the lower lifting platform plate 10-1 continues to descend a certain distance under the action of hydraulic pressure. At this time, the inner side of the pressure plate of the airbag assembly 10-3 is lifted upward by the side edge of the lower mold 10-2. Under the action of the lever principle, the outer edge of the pressure plate further compresses the airbag downward. This structure can further avoid the lower mold assembly 10 from generating a rigid impact on the forming platform 6, and improve the stability and safety of the equipment operation.

[0037] In this embodiment, the forming mechanism of the forming assembly includes a forming hydraulic cylinder installed in the middle of the forming machine frame 9. The lower end of the piston rod of the forming hydraulic cylinder is fixedly connected to the middle of the upper lifting platform plate 16-1. During operation, the piston rod of the forming hydraulic cylinder extends downward, and the upper lifting platform plate 16-1 and its upper mold 16-2 descend.

[0038] In this embodiment, the demolding mechanism of the forming assembly includes a lifting frame 8 located above the forming machine frame 9. Guide sleeves are provided at the four corners of the forming machine frame 9, and guide columns 14 are provided inside each guide sleeve. The upper end of each guide column 14 is fixedly connected to the lifting frame 8, and the lower end is fixedly connected to the lower lifting platform plate 10-1. A demolding hydraulic cylinder that drives the lifting frame 8 to move up and down is also installed on the forming machine frame 9. During operation, when the piston rod of the demolding hydraulic cylinder rises, the lifting frame 8 and the lower mold assembly 10 rise. At this time, the height of the upper mold assembly 16 is maintained, and the pressure heads of the upper mold 16-2 further descend in the mold cavity, pushing the formed brick blank in the mold cavity downwards to complete the demolding.

[0039] In this embodiment, the traveling drive assembly 7 includes a traveling drive motor 7-1 mounted on the side of the forming machine frame 9, with traveling gears 7-2 mounted at both ends of its output shaft. Travel racks 7-4 (not shown in the figure, the traveling racks 7-4 are fixed to the top sides of the main frame 1 via mounting seats) are mounted on both sides of the top of the main frame 1. The traveling gears 7-2 mesh with the traveling racks 7-4 on their respective sides. Furthermore, slide rails 7-3 are also mounted on both sides of the top of the main frame 1, and sliders are provided on the slide rails 7-3. The sliders are fixedly connected to the side base of the forming machine frame 9. When the traveling drive motor 7-1 drives the traveling gears 7-2 to rotate forward, the forming assembly moves to the left; conversely, when the traveling drive motor 7-1 drives the traveling gears 7-2 to rotate in the opposite direction, the forming assembly moves to the right.

[0040] Please see Figure 2 and Figure 3 It can be seen that:

[0041] The material feeding device includes a side frame 2 located on the side of the main frame 1, a hopper 4 mounted on top of the side frame 2, and a material feeding assembly 3 that receives material from the hopper 4 and feeds it onto the lower die assembly 10 which falls onto the forming platform 6. The mixed blank is injected into the hopper 4, and a cylinder-controlled valve is installed at the bottom opening of the hopper 4. When the valve is opened, the mixed blank in the hopper 4 is discharged downwards.

[0042] A support base plate 11 is installed in the middle of the side frame 2. The fabric assembly 3 includes a fabric frame 3-1 with open top and bottom, a fabric feeder 3-2 inside and a fabric drive mechanism 3-4 outside. The mixed blank discharged from the hopper 4 is injected into the fabric frame 3-1. The fabric frame 3-1 rests on the support base plate 11. It also includes a push-pull drive mechanism that provides a front and rear push-pull action for the fabric frame 3-1.

[0043] The fabric feeder 3-2 and the fabric drive mechanism 3-4 are used to agitate the mixed fabric within the fabric frame 3-1, preventing material jamming and improving the uniformity and stability of the fabric. In this embodiment, the fabric feeder 3-2 includes multiple fabric shafts, each with fabric teeth mounted on it. The fabric shafts and fabric teeth are located inside the fabric frame 3-1. It also includes a connecting seat located outside the fabric frame 3-1, which is connected to the shaft ends of each fabric shaft via multiple small swing arms. The fabric drive mechanism 3-4 includes a fabric motor with a turntable mounted on its output shaft, and a fabric pull rod. The front end of the fabric pull rod is hinged to the top of the connecting seat, and the rear end is eccentrically hinged to the turntable.

[0044] During operation, the fabric drive mechanism 3-4 drives the turntable to rotate. Since the fabric tie rod and the turntable are eccentrically hinged, the fabric tie rod is intermittently pushed and pulled back and forth, and the connecting seat is intermittently pushed and pulled back and forth. Since the shaft ends of each fabric shaft are connected to the connecting seat by small swing arms, each fabric shaft rotates intermittently in the forward and reverse directions at small angles. The fabric teeth on each fabric shaft swing left and right. Within the fabric frame 3-1, the left and right swinging fabric teeth have a conveying disturbance effect on the mixed blank, avoiding material jamming and promoting the smooth downward fall of the mixed blank into the mold cavity of the lower mold 10-2.

[0045] In this embodiment, the push-pull drive mechanism includes two opposing upper swing arms 3-6, which are connected to the top of the side frame 2 via a pivot 3-7. It also includes two opposing lower swing arms 3-5, the upper ends of which are hinged to the lower ends of the upper swing arms 3-6, and the lower ends of which are hinged to the rear of the fabric frame 3-1. A swing hydraulic cylinder 3-8 is installed between the side frame 2 and the upper swing arms 3-6. When the piston rod of the swing hydraulic cylinder 3-8 extends, the upper swing arm 3-6 swings backward, and the lower swing arm 3-5 pulls the fabric frame 3-1 backward. Conversely, when the piston rod of the swing hydraulic cylinder 3-8 retracts, the upper swing arm 3-6 swings forward, and the lower swing arm 3-5 pushes the fabric frame 3-1 forward, reaching the fabric placement station, which is above the forming platform 6.

[0046] In this embodiment, a fabric guiding mechanism is also included to guide the movement of the fabric frame 3-1, thereby improving the stability of the movement of the fabric frame 3-1. Side rollers 3-3 are installed on the side of the fabric frame 3-1. The fabric guiding mechanism includes a moving track 12 installed on the inner side of the middle of the side frame 2 and a mold track 15 installed on the lower mold 10-2. An extension platform 5 is also installed on the side of the main frame 1 and the forming platform 6, and an extension track 13 is installed on the extension platform 5. When the forming component moves to the forming station, the aforementioned moving track 12, mold track 15 and extension track 13 together constitute a guiding track for the side rollers 3-3 of the fabric frame 3-1 to roll and move. In this way, the fabric frame 3-1 can maintain stable movement during the complete forward fabric laying and backward retraction process.

[0047] Operation process:

[0048] The forming assembly moves to the left, causing the lower mold assembly 10 to move directly above the forming platform 6. The piston rod of the demolding hydraulic cylinder retracts, causing the lower mold assembly 10 to fall onto the forming platform 6. The bottom surface of the lower mold 10-2 contacts the pad 6-6, thus closing the bottom openings of each cavity of the lower mold 10-2.

[0049] Then, the feeding assembly 3 actuates, and the feeding frame 3-1 moves forward along the guide rail. When the feeding frame 3-1 leaves the support base plate 11 and moves onto the lower mold 10-2, its bottom opens, allowing the mixed blank to enter the mold cavity downwards. During the feeding operation, the feeder 3-2 and the feeding drive mechanism 3-4 operate to agitate the mixed blank within the feeding frame 3-1, promoting its downward entry into the mold cavity and preventing jamming. After feeding is completed, the feeding assembly 3 actuates again, and the feeding frame 3-1 retracts back onto the support base plate 11.

[0050] Then, the piston rod of the forming hydraulic cylinder extends downward, the upper mold assembly 16 descends, and each pressure head of the upper mold 16-2 enters the mold cavity of the lower mold 10-2. Under the action of hydraulic pressure, the mixed blank is pressed into a brick blank within the mold cavity. After forming is completed, the piston rod of the forming hydraulic cylinder retracts, and the piston rod of the demolding hydraulic cylinder extends upward, causing the lower mold assembly 10 to rise and leave the forming platform 6.

[0051] The pressing assembly then moves to the right to the demolding and unloading position. During this process, each pressed brick blank remains within its respective cavity in the lower mold 10-2. After the pressing assembly moves directly above the brick blank stacking machine, the piston rod of the demolding hydraulic cylinder retracts. While the upper mold 16-2 descends, the height of the lower mold 10-2 remains unchanged. The pressure head of the upper mold 16-2 then pushes the brick blanks downwards from the mold cavity, completing the demolding of the brick blanks. Afterward, the equipment returns to its initial state.

[0052] After demolding, the brick blanks are stacked layer by layer on a brick stacking machine to form a complete brick stack. Finally, forklifts and other equipment are used to transfer the brick stack to the curing site.
