Description

Technical Field

[0001] The invention relates to the technical field of water-permeable brick processing, in particular to a forming device for building composite water-permeable bricks. Background Art

[0002] Permeable bricks are also called seepage bricks, Dutch bricks, etc. They are new green and environmentally friendly building materials. The raw materials are mainly cement, sand, slag, fly ash and other environmentally friendly materials. They are formed by high pressure and cannot be fired at high temperature. The whole brick is compressed at one time and cannot be pressed in layers to form homogeneous bricks that are consistent from top to bottom. It has good water permeability and strong anti-slip function; long service life; high anti-freeze performance and salt-alkali resistance; not easy to break, higher compression and flexural strength than similar products, safe driving; low maintenance cost, easy to replace, convenient for underground pipeline burial; various colors and shapes, set off with the surrounding environment, natural and beautiful.

[0003] Composite permeable bricks include a permeable surface layer and a permeable base layer. First, the base aggregate is put into the mold, and after preliminary pressing, the surface is covered with the surface material, and then a thorough pressurization is performed to complete the permeable brick molding work. The molding of permeable bricks generally requires the mold to be completed with a pressurized die head. After molding, a vibration device is used to drive the entire device to vibrate, and the density of the permeable brick is further increased through vibration. The demoulding is completed by the vibration process, and the demoulding of the permeable bricks is transferred to other locations for placement and maintenance.

[0004] The surface and base of permeable bricks contain a certain amount of binder. When the base aggregate is initially pressed, the binder may cause part of the aggregate to adhere to the surface of the die. When the surface aggregate is covered for secondary pressing, the surface of the permeable brick may be uneven or there may be residual base aggregate, resulting in an unsightly surface and affecting the quality of production. At present, there are some devices that can scrape off the aggregate on the surface of the die to address this phenomenon, but this type of equipment generally scrapes off the aggregate directly and discharges it. The aggregate is mostly wet in texture. If the discharged aggregate is not handled immediately, it will become complete waste after a period of time and cannot be used again, causing a certain amount of waste. Summary of the invention

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 5 In an embodiment of the present invention, a forming device for a composite permeable building brick comprises a processing table 11, a support frame 12 is mounted on the processing table 11, a forming structure 6 is mounted on the support frame 12, and the forming structure 6 comprises a forming mold 65 and a pressurizing die head 62; a base layer feeding structure 4 and a surface layer feeding structure 3 are mounted on both sides of the processing table 11, the base layer feeding structure 4 comprises a primary feeding frame 41, and the surface layer feeding structure 3 comprises a secondary feeding frame 31;

[0030] A scraping structure 5 is installed on one side of the secondary feeding frame 31 close to the support frame 12, and the scraping structure 5 is used to scrape the residual aggregate on the surface of the pressure die 62; the scraping structure 5 includes a material guide box 51, and an inclined scraper 52 is installed on the material guide box 51;

[0031] A recovery structure 7 is installed at one end of the molding die 65 away from the secondary feeding frame 31, and the recovery structure 7 includes slide bars 73 installed on both sides of the molding die 65, and a slider 72 is slidably installed on the slide bar 73, and a primary spring 74 connected to the slider 72 is sleeved on the slide bar 73, and the slider 72 is connected to a material guide groove 71 located on the surface of the molding die 65, and the material guide groove 71 is through on both sides;

[0032] A vibration structure 2 is installed on a side of the processing table 11 away from the support frame 12, and the vibration structure 2 is used to drive the processing table 11 to vibrate and assist in demoulding the permeable bricks.

[0033] This device uses a processing mold and a pressure die head 62 located on the surface of the processing table 11 to jointly produce permeable bricks. The base feeding structure 4 and the surface feeding structure 3 are respectively located on both sides of the processing table 11. This device does not limit the setting of the hopper. The hoppers can be respectively set on both sides of the processing table 11 for feeding the base aggregate and the surface aggregate, or other feeding methods such as manual operation can be used. During the processing, the forming mold 65 is placed on the processing table 11. The base aggregate is first arranged in the mold groove 65 by the first-level feeding frame 41. The pressure die head 62 is initially pressed down to shape, and then the pressure die head 62 is raised. The surface aggregate is covered on the base aggregate using the second-level feeding frame 31, and the pressure die head 62 is fully pressurized to form. After forming, the forming mold 65 is raised, and the vibration structure 2 is used to drive the equipment to vibrate. The brick blank is further solidified by vibration and gradually falls off downward to complete demolding.

[0034] The above process is a complete processing and forming process. After the first round of pressurization by the pressurizing die head 62, there is a high possibility that base aggregate will remain on the surface. Therefore, the device is provided with a recovery structure 7 located at one end of the surface of the forming mold 65 and a scraping structure 5 located on the secondary feed frame 31 to cooperate in cleaning these residual aggregates. As the secondary feed frame 31 moves inward, while laying the surface aggregate on the forming mold, the scraper 52 will also scrape the aggregate residue on the pressurizing die head 62 and collect it in the guide box 51 until the guide box 51 comes into contact with the guide groove 71, and the internal residue enters the guide groove 71. After the first round of brick production is completed, the primary feed frame 41 will move to the top of the forming mold 65 again to lay the raw materials. At the same time, the primary feed frame 41 will push the guide groove 71 that runs through the upper and lower parts to move on the surface of the forming mold 65, and put the internal residue into the mold groove 65, mixing the newly added base aggregate, and using it as the raw material for brick production. The slide block 72 cooperates with the slide rod 73 and the primary spring 74 to enable the material guide trough 71 to automatically return to its original position after the material distribution is completed, without affecting the subsequent brick production process.

[0035] The device utilizes the original production process of the brick blank, realizes the function of automatically cleaning the pressure die head 62 during production, and avoids the residual residue affecting the surface quality of the brick blank. At the same time, the device can immediately put the cleaned residue into the next round of production, and will not cause the residue to be dehydrated and dried after being left for a long time and become garbage. Therefore, the device can effectively reduce the waste of materials and reduce the process of garbage disposal.

[0036] As another embodiment of the present invention, please refer to Figure 3 and Figure 4 The material guide box 51 has an opening on one side close to the forming mold 65, and the material guide box 51 is connected to the secondary feed frame 31 through a support rod 53. A bottom plate 54 is rotatably mounted on the material guide box 51, and a guide plate 55 is mounted on the outer side of the bottom plate 54. A torsion spring 56 is installed at the connection between the bottom plate 54 and the material guide box 51, and a support plate 711 is installed on the side of the material guide groove 71 close to the material guide box 51. The bottom of the material guide box 51 is open, and a bottom plate 54 is provided at the bottom. Under the action of the torsion spring 56, the bottom plate 54 is attached to the bottom of the material guide box 51 to prevent leakage of the material guide box 51. When the material guide box 51 moves to the position of the material guide groove 71, the support plate 711 abuts against the guide plate 55 to make the bottom plate 54 rotate downward. The bottom of the material guide box 51 is open, and the raw materials fall into the material guide groove 71. After the material guide box 51 retreats a certain distance, the bottom plate 54 automatically resets. Even if there are residues in the material guide box 51 that cannot fall in time, they will not fall on the surface aggregate.

The two eccentric wheels 26 are located on the same horizontal plane. During the rotation process, due to the deviation between the center of the rotating shaft 27 and the center of gravity of the eccentric wheel 26, a certain centrifugal force will be generated. The centrifugal forces of the two relatively rotating eccentric wheels 26 in the horizontal direction are separated and offset each other, and are superimposed in the vertical direction, so that the entire device can vibrate continuously.

The primary feed frame 41 firstly puts the base aggregate into the molding die 65, and the pressure die head 62 performs preliminary compaction, and then the secondary feed frame 31 puts the surface aggregate into the molding die 65, and at the same time, the scraping structure 5 is used to scrape off the residue on the pressure die head 62, and transfer it to the guide groove 71 on the molding die 65, and the pressure die head 62 is pressurized again to mold the brick blank. After the first batch of brick blanks are transferred, the primary feed frame 41 replenishes the raw materials again, and the originally collected residues will be put into the molding die 65 together, which will be used as the raw materials for the next molding. Therefore, the device can continuously clean the pressure die head 62 during the processing process to prevent the residues from affecting the quality of the brick blanks. At the same time, the cleaned residues can be directly used for subsequent processing, without generating garbage, reducing the waste of raw materials, and also reducing the workload of garbage disposal.
