[0002] Unburned bricks refer to a new type of building material made from fly ash, coal slag, coal gangue, tailings, chemical slag or natural sand, sea mud, etc. (one or more of the above raw materials) as the main raw materials without high-temperature calcination. They are often used in building walls, floor paving and other scenes. Unburned bricks are pressed and formed by brick machine equipment. Specifically, the mixed blank is injected into the lower mold, and then the upper mold is lowered to close the mold and a certain vibration is applied. The brick blank is pressed and formed. After demolding, the brick blank needs to be transferred to the curing site for a certain process time. During the curing process, the brick blank gradually builds up structural strength and forms the final unburned brick product.
[0003] The unburned brick production line usually includes material supply equipment, brick machine equipment, brick making and brick output line, maintenance facilities, and stacking and packaging equipment. According to the process flow, the unburned bricks are pressed and formed by the brick machine equipment, and then transferred to the maintenance facilities for maintenance. After the maintenance is completed, operations such as spraying and drying are required according to product requirements. Finally, the unburned bricks that have been cured are stacked to form a brick stack.

[0024] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.
[0025] See also Figure 1 The utility model of the unburned brick production line includes a brick making machine 10, a mold changing and plate feeding device 20 is provided at the rear of the brick making machine 10, a brick discharging line 11 is provided at the front, and a cement tank 1, an aggregate storage and supply device 2, a blank mixing device 3 and a blank conveyor 4 for supplying unburned brick blanks are provided on the outside of the brick making machine 10, and a material storage and supply device 5, a material weighing and supply device 6, a material mixing device 7 and a material conveyor 8 are provided for supplying unburned brick fabrics.
[0026] The brick making machine 10 is an existing device. In terms of structure, the brick making machine 10 includes a vibration platform, a blank feeding device, a surface feeding device, etc. The blank feeding device injects the mixed blank into the lower mold, and the surface feeding device spreads the surface on the surface of the blank. Then the upper mold descends and closes with the lower mold, and at the same time, a vibration action is applied to complete the pressing and forming of the brick blank. A brick making pallet is arranged below the lower mold, so that the brick blank is located on the brick making pallet after demolding, and then the brick making pallet carrying the brick blank is transferred to the brick output line 11. The structure, function and operation mode of the brick making machine 10 are not described in detail.
[0027] The mold-changing and plate-feeding device 20 is used to supply the aforementioned brick-making pallet to the brick-making machine 10. On the other hand, since the unburned bricks need to be frequently selected and produced, it involves the operation of replacing the mold. The mold-changing and plate-feeding device 20 is used to assist the brick-making machine 10 in replacing the mold during the selection and production. The brick-discharging line 11 is used to transport and transfer the pressed brick blanks and brick-making pallets to the subsequent maintenance site 23.
[0028] As mentioned above, the structure of unburned bricks is composed of blanks and fabrics, and the fabrics are composed of aggregates (fly ash, coal slag, coal gangue, tailings, chemical slag or natural sand, etc.) and cement, and the fabrics are also mixed with multiple materials. By arranging a cement tank 1, an aggregate storage and supply device 2, a blank mixing device 3 and a blank conveyor 4 for supplying unburned brick blanks on the outside of the brick making machine 10, the blanks are automatically configured and supplied to the brick making machine 10. By arranging a fabric storage and supply device 5, a fabric weighing and supplying device 6, a fabric mixing device 7 and a fabric conveyor 8 for supplying unburned brick fabrics on the outside of the brick making machine 10, the fabrics are automatically configured and supplied to the brick making machine 10.
[0029] like Figure 1 As shown in the figure, both the blank mixing device 3 and the fabric mixing device 7 use bolt stirring to mix the blank and the fabric respectively, so the blank mixing device 3 and the fabric mixing device 7 both include a stirring tank located at a high position, cement and aggregate are fed into the stirring tank of the blank mixing device 3, and the fabric is fed into the stirring tank of the fabric mixing device 7.
[0030] In this embodiment, the aggregate storage and supply device 2 has multiple chambers for storing aggregates, each chamber stores a type of aggregate, and the cement in the cement tank 1 and the aggregates in each chamber of the aggregate storage and supply device 2 are lifted and transported to the blank mixing device 3 for mixing by equipment such as a screw conveyor or a bucket conveyor. The mixed blanks are released by the blank mixing device 3 to the blank conveyor 4 below, and the blank conveyor 4 transports the blanks to the blank hopper of the brick making machine 10.
[0031] In this embodiment, the fabric storage and supply device 5 has multiple chambers for storing fabrics, each chamber stores a type of fabric, and the fabrics in each chamber are sent to the fabric weighing and supply device 6, and after weighing, they are sent to the stirring tank of the fabric mixing device 7 for mixing. The mixed fabrics are released by the fabric mixing device 7 to the fabric conveyor 8 below, and the fabric conveyor 8 conveys the fabric to the fabric hopper of the brick making machine 10.
[0032] It also includes a brick conveyor line 17, with an elevator 12 at the end of the brick output line 11 and the beginning of the brick output line 17, and a transfer conveyor line 14 in front of the two elevators 12. The brick output line 11 is used to transfer the pressed bricks to the curing site 23, the conveyor line 17 is used to transfer the bricks that have completed curing to the packaging process behind, and the transfer conveyor line 14 is used to transfer the bricks. Figure 1 As shown in the figure, in the transfer conveyor line 14 and the curing place 23, the bricks supported by the brick-making pallet are placed on the brick-blade holder, and in order to make full use of the curing space, the brick-blade holder is a three-dimensional multi-layer holder, and the elevator 12 arranged at the end of the brick output line 11 is used to place the brick-making pallet and the bricks into the spaces of each layer of the brick-blade holder layer by layer, and the elevator 12 at the head end of the brick-blade conveyor line 17 is used to remove the bricks that have completed curing from the brick-blade holder layer by layer and place them one by one on the brick-blade conveyor line 17.
[0033] The transfer conveyor line 14 includes a supporting roller driven by a driving machine, on which a supporting wheel is installed, and the brick blank bracket falls on the supporting wheel. The supporting roller is driven by the driving machine to rotate forward or reverse, so that the brick blank bracket is shifted on the transfer conveyor line 14.
[0034] See also Figure 2 , we can see that:
[0035] The hoist 12 includes a hoisting frame 12-1, a lifting frame 12-2 is provided inside the hoisting frame 12-1, a telescopic fork frame 12-3 is installed in the hoisting frame 12-2, a lifting drive component for driving the lifting frame 12-2 to move up and down and a counterweight frame 12-4 that is synchronously lifted when the lifting frame 12-2 moves up and down are installed on the hoisting frame 12-1, and a telescopic drive component is installed between the lifting frame 12-2 and the telescopic fork frame 12-3.
[0036] The lifting drive assembly drives the lifting frame 12-2 to lift and shift with the telescopic fork frame 12-3, so that the telescopic fork frame 12-3 can fork the brick pallet and the brick blank at different heights on the brick blank bracket. The telescopic drive assembly drives the telescopic fork frame 12-3 to move forward and backward, and fork the brick pallet and the brick blank when moving forward, and separate the brick pallet and the brick blank from the brick blank bracket when moving backward. Therefore, the operation mode of the hoist 12 is similar to that of a forklift, and the brick pallet and the brick blank are located on the left and right front forks in front of the telescopic fork frame 12-3 during operation.
[0037] In order to improve the stability of the lifting frame 12-2 when it is lifted or lowered, a lifting guide structure consisting of guide wheels and guide rails can be set between the lifting frame 12-1 and the lifting frame 12-2. In order to improve the stability of the telescopic fork frame 12-3 when it is moved forward and backward, a telescopic guide structure consisting of guide rails and track blocks can be set between the lifting frame 12-2 and the telescopic fork frame 12-3.
[0038] A trench 25 is provided in front of the transfer conveyor line 14, and a trench inner rail 26 is provided in the trench 25, and a ferry vehicle 13 is provided on the trench inner rail 26. A maintenance site 23 is provided in front of the trench 25, and a plurality of maintenance ground rails 22 and maintenance brackets 24 are installed in the maintenance site 23. The ferry vehicle 13 is used to ferry and shift the brick blank bracket between the transfer conveyor line 14 and the maintenance site 23. Figure 1 As shown in FIG. 1 , a group of maintenance ground rails 22 are provided on the inner bottom surface of each group of maintenance brackets 24 . When the brick blank brackets are sent into the maintenance place 23 , the maintenance brackets 24 provide stable support for the brick blank brackets.
[0039] In this embodiment, the ferry vehicle 13 includes a ferry vehicle and a ferry vehicle. The ferry vehicle moves horizontally along the inner rail 26 in the ditch and is provided with an on-vehicle track. The ferry vehicle is located on the on-vehicle track. The ferry vehicle extracts the brick blank bracket from the transfer conveyor line 14, moves along the maintenance ground rail 22 and places it on the maintenance bracket 24, and takes out the brick blank bracket that has completed maintenance from the maintenance site 23 and places it on the transfer conveyor line 14.
[0040] As shown in the figure, another short ground rail is installed on the ground below the end of the transfer conveyor line 14. When the ferry vehicle 13 moves to the front of the end of the transfer conveyor line 14, its on-vehicle track is connected to the short ground rail. At this time, the ferry vehicle can move to the outside of the ditch 26 and below the brick blank bracket. The ferry vehicle then lifts the brick blank bracket to a certain height to separate its bottom from the transfer conveyor line 14. The ferry vehicle then returns to the ferry mother vehicle carrying the brick blank bracket. The ferry mother vehicle selectively moves to the end of a group of maintenance supports 24 according to the space conditions in the maintenance site 23. At this time, the on-vehicle track is connected to the maintenance ground rail 22 of this group of maintenance supports 24. The ferry vehicle travels onto the maintenance ground rail 22 and moves along the maintenance ground rail 22 to the depth of the maintenance site 23. After reaching the appropriate position, the brick blank bracket is placed down on the maintenance support 24, and then the ferry vehicle returns to the ferry mother vehicle. Similarly, taking out the green brick bracket from the curing place 23 and transferring it to the transfer conveyor line 14 is the reverse process of the above-mentioned operation, which will not be described in detail here.
[0041] A grabbing and coating device 18 is provided at the outer side of the end of the brick conveyor line 17, and a pallet return line 19 is provided between the grabbing and coating device 18 and the mold-changing and feeding device 20. The grabbing and coating device 18 is used to grab and stack the unburned bricks on the brick-making pallet carrying the final unburned bricks moved to the end of the brick conveyor line 17, and form a brick pile 27 by stacking, which is convenient for the subsequent delivery. In the process of grabbing and stacking the unburned bricks layer by layer, a protective film needs to be set between the layers, so that the unburned bricks will not be squeezed, bumped or rubbed against each other during transportation, thereby ensuring the product quality. After the unburned bricks are grabbed from the brick-making pallet, the brick-making pallet is vacant (called brick-board separation), and the pallet return line 19 is used to transfer to the front of the brick-making machine 10, that is, to the mold-changing and feeding device 20 again, so that the brick-making pallet can be used in a cyclic turnover manner.
[0042] See also Figure 3 , we can see that:
[0043] The code grabbing and laminating device 18 includes a code grabbing and laminating frame 18-1, a code grabbing and laminating translation and lifting assembly 18-5 is installed on the top of the code grabbing and laminating frame 18-1, a code grabbing assembly 18-2 is installed at the bottom of the code grabbing and laminating translation and lifting assembly 18-5, a rotary drive assembly is installed between the code grabbing and laminating translation and lifting assembly 18-5 and the code grabbing assembly 18-2, and a laminating assembly 18-4 is also installed on the code grabbing and laminating frame 18-1. Since the code grabbing component 18-2 is installed at the bottom of the code grabbing coating translation and lifting component 18-5 and the rotary drive component, the code grabbing component 18-2 can perform translational movement, lifting movement and rotational rotation. The translational movement and lifting movement can realize translation and lifting displacement after grabbing the unburned bricks, thereby realizing code grabbing and stacking. The rotational rotation can be turned 90° when stacking the next layer of unburned bricks, so that the two adjacent layers of unburned bricks are placed at 90°, that is, staggered. This can improve the density of the brick stack 27 and avoid looseness and collapse during transportation.
[0044] The code grabbing and laminating translation and lifting assembly 18-5 is composed of a translation assembly and a lifting assembly: the translation assembly includes a top frame that moves along the top of the code grabbing and laminating frame 18-1, and walking wheels are installed at the four corners of the top frame. A walking motor is also installed on the top frame. In order to improve the stability of the translation movement, a guide structure composed of guide wheels and guide rails can be installed between the top frame and the code grabbing and laminating frame 18-1; the lifting assembly includes a lifting guide installed in the middle of the top frame, a lifting bracket is installed in the lifting guide, a rotary drive assembly is installed at the bottom of the lifting bracket, and the code grabbing assembly 18-2 is installed at the bottom of the rotary drive assembly. A sprocket can be installed at the lower part of the lifting bracket, and a sprocket is installed on the lifting guide, so that the middle part of a chain bypasses the sprocket on the lifting bracket, and both ends extend upward and bypass the sprocket on the lifting guide. One end of the chain is fixed, and the other end is pulled and driven by a drive motor. When the end of the chain is moved outward, the lifting bracket and its accessories rise, and conversely, when the end of the chain is moved inward, the lifting bracket and its accessories descend.

The rotary drive motor drives the rotary main gear to rotate, and the rotary main gear drives the code grabbing base and its four sets of clamping claws and the code grabbing cylinder to rotate.
[0046] In this embodiment, the coating assembly 18-4 includes a coating lifting frame and a lifting drive assembly that drives the coating lifting frame to move up and down. A unwinding assembly that unwinds the protective film reel and a transverse driving assembly that drives the unwinding assembly to move transversely are installed on the coating lifting frame. The unwinding assembly has a mounting shaft for mounting the protective film reel and a damping regulator for adjusting and setting the rotation damping of the mounting shaft.
[0047] The lifting drive assembly can be a chain driven by a motor, and the film lifting frame is fixedly connected to the chain. In order to improve the stability of lifting, a guide structure consisting of a guide wheel and a guide track can be installed between the film lifting frame and the code grabbing and laminating machine frame 18-1. The lateral movement drive assembly can be a belt driven by a motor, and the unwinding assembly is fixedly connected to the belt. In order to improve the stability of lateral movement, a guide structure consisting of a guide track and a track block can be installed between the unwinding assembly and the film lifting frame.
[0048] The unwinding assembly includes a translation base, on which an axle seat is installed, and the root of the mounting shaft is located in the axle seat, so that the mounting shaft can rotate flexibly, and the damping regulator is used to set the rotation damping effect for the mounting shaft to avoid excessive release of the protective film during the pulling and unwinding process. The damping regulator may include a pulley installed at the root of the mounting shaft and a damping bracket installed on the translation base, and a belt segment is installed on the damping bracket, one end of the belt segment is fixedly connected to the damping bracket, and the other end is fixedly connected to the adjusting bolt on the damping bracket, and the middle part of the belt segment bypasses the pulley on the mounting shaft, and the tension of the belt segment is adjusted by adjusting the bolt to provide different degrees of friction to the pulley.
[0049] In this embodiment, a tray feeding rack 18-3 is also provided below the grabbing and laminating rack 18-1, and the tray of unburned bricks is placed on the tray feeding rack 18-3. The unburned bricks are grabbed and stacked layer by layer by the grabbing assembly 18-2 on the tray on the tray feeding rack 18-3, and the laminating assembly 18-4 lays a protective film between the layers while grabbing the bricks.
[0050] A finished product output line is provided in front of the pallet feeding rack 18-3. After the brick stack 27 is formed, the pallet carrying the brick stack 27 is transferred to the finished product output line and moves backward as a whole. After reaching the end, a forklift is used to transfer the brick stack 27 to a vehicle for shipment.
[0051] See also Figure 4 , we can see that:
[0052] The mold-changing and plate-feeding device 20 comprises a mold-changing and plate-feeding frame 20-1, and the brick-making mold 28 is placed on a mold bracket above the inside of the mold-feeding plate bracket 20-1. Generally, the brick-making mold 28 has multiple models. According to the current production situation of the brick-making machine 10, several brick-making molds 28 to be used in the short term are transferred from the mold yard to the mold bracket of the mold-changing and plate-feeding device 20 by a forklift.
[0053] A mold shifting assembly consisting of a mold changing translation assembly 20-2, a mold changing lifting assembly 20-3, a lifting column 20-4 and a lifting support beam is provided on the mold feeding plate frame 20-1. The mold shifting assembly lifts, shifts and lowers the brick-making mold 28 to achieve auxiliary mold changing operations.
[0054] The mold changing translation assembly 20-2 is a mold changing translation frame, which moves along the top of the mold feeding plate frame 20-1. A driving motor is installed on the mold changing translation frame and a traveling gear is installed on the output shaft of the driving motor. A traveling rack is installed on the mold feeding plate frame 20-1, and the traveling gear rolls along the traveling rack. In order to improve stability, a guide structure can be set between the mold feeding plate frame 20-1 and the mold changing translation frame.
[0055] The mold changing lifting assembly 20-3 includes a mold changing lifting frame located above the mold changing translation frame and a hydraulic cylinder installed between the mold changing translation frame and the mold changing lifting frame. Sleeves are provided at the four corners of the mold changing translation frame and each lifting column 20-4 is located in each sleeve. The upper end of each lifting column 20-4 is fixedly connected to the four corners of the mold changing lifting frame. The lifting support beam is installed between the lower ends of the two lifting columns 20-4 on the left and between the lower ends of the two lifting columns 20-4 on the right.
[0056] The hydraulic cylinder drives the mold changing lifting frame to move up and down, and the left and right lifting beams move up and down synchronously. When the left and right lifting beams are translated and displaced, their inner edges are located below the edges of the brick-making mold 28 on both sides. In this way, when the lifting beams are raised, the brick-making mold 28 is lifted up by the two lifting beams, and then the brick-making mold 28 is put down after displacement.
[0057] A mold alignment platform 20-5 is also installed at the front of the mold-changing and feeding plate rack 2, which is used to align the brick-making mold 28 before installing it on the brick-making machine 10, and improve the position accuracy through alignment, so that the brick-making machine 10 can smoothly use the brick-making mold 28.
