Description

Technical Field

[0001] This invention mainly relates to the field of new building materials, specifically a composite molding system and molding method for building energy-saving materials. Background Technology

[0002] Energy-saving insulating bricks are a type of special wall material with excellent thermal insulation properties. They reduce building energy consumption by blocking heat transfer. Their core performance indicator is thermal conductivity (typically required to be ≤0.045W / (m·K)), and their comprehensive energy-saving rate can reach 30%–65%. Due to their special material properties, they are now widely used in building exterior walls and industrial kilns as insulation materials. In industrial applications and civilian applications in extremely cold regions, where higher insulation performance is required, composite material energy-saving insulating bricks can better achieve temperature insulation and maintain a better temperature. Double-layer composite energy-saving insulating bricks, based on the combination of a working layer and an insulation layer, have higher insulation performance. Adopting the design concept of "1+1>2," they achieve the dual functions of low / high temperature resistance, corrosion resistance, and energy-saving insulation. In industrial applications, this is mainly reflected in refractory insulation materials. The working layer directly contacts high-temperature materials, is wear-resistant and corrosion-resistant, while the insulation layer faces the furnace shell or exterior wall, used to reduce the cylinder temperature and save energy. In the civilian sector, the working layer faces the extreme cold weather on the outer side of the wall, making it wear-resistant and corrosion-resistant, while the insulation layer faces inward to insulate against the temperature and ensure indoor temperature.

[0003] During the pressing process, the working layer and the insulation layer of this type of composite double-layer insulation brick are pressed together with the filling material. However, during the processing, since the two materials need to be filled into the mold at the same time, the filling of the raw materials needs to be manually controlled to avoid the two materials mixing and affecting the brick forming. Therefore, the processing cost of this type of composite double-layer insulation brick is high and the processing efficiency is low. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a composite molding system and method for building energy-saving materials, which can automatically feed and mold composite double-layer insulation bricks, improving the molding efficiency and quality of the bricks.

[0005] To achieve the above objectives, the present invention employs the following technical solution: A composite molding system and method for building energy-saving materials includes a molding machine. The molding machine includes a molding frame, with an operating table in the middle for installing molding molds. The two side support frames of the molding frame are gantry structures. The middle of the operating table is a molding cavity. An auxiliary mechanism is provided on one side of the molding machine, and a filling mechanism is provided on the other side. The filling mechanism includes a filling slide rail, a filling cylinder, and a filling hopper. The two sides of the filling hopper are slidably connected to the filling slide rail. The filling cylinder is used to push the filling hopper to perform reciprocating linear motion. The filling hopper has two symmetrically arranged filling cavities that are not connected to each other. The auxiliary mechanism includes an auxiliary slide rail, an auxiliary slide rail, and a filling cylinder. An auxiliary cylinder and an auxiliary mold cavity are provided. The two sides of the auxiliary mold cavity are slidably connected to auxiliary slide rails. The bottom surface of the auxiliary mold cavity is in contact with the top surface of the operating table. The auxiliary cylinder is used to push the auxiliary mold cavity to perform reciprocating linear motion. An isolation plate is slidably arranged inside the auxiliary mold cavity. A lifting cylinder is vertically arranged on the side of the auxiliary mold cavity near the auxiliary cylinder. When the lifting cylinder is in the extended state, the isolation plate is removed from the forming mold cavity and the bottom of the isolation plate is coplanar with the bottom surface of the auxiliary mold cavity. When the lifting cylinder is in the retracted state, the isolation plate falls into the forming mold cavity and the bottom of the isolation plate is in contact with the bottom surface of the forming mold cavity. When the filling hopper is filling, the two filling cavities are arranged on both sides of the isolation plate.

[0006] This invention achieves automated filling of two raw materials through the cooperation of a filling device and an auxiliary device, thereby improving the efficiency and accuracy of material filling, increasing production efficiency, and reducing production costs.

[0007] Preferably, the diameter of the bottom outlet of the filling cavity is less than half the diameter of the top opening of the auxiliary mold cavity, and the top of the filling cavity has a conical cavity.

[0008] Preferably, a slide is provided below the filling mechanism, and the bottom of the filling cavity is in contact with the slide. When the auxiliary mold cavity is connected with the forming mold cavity, the front end of the slide abuts against the auxiliary mold cavity.

[0009] The sliding table is designed to block the bottom outlet of the packing chamber, ensuring smooth transfer of raw materials.

[0010] Preferably, a sliding cylinder is provided at the bottom of the slide table. When the sliding cylinder extends, the slide table docks with the auxiliary mold cavity. When the sliding cylinder retracts, the slide table disengages from the area where the molding mold cavity is located.

[0011] Preferably, the operating table is provided with a pair of guide grooves on one side of the auxiliary mechanism. The guide grooves correspond to the two sides of the auxiliary mold cavity that are divided by the partition plate, and the bottom of the guide grooves is connected to the return material mechanism.

[0012] The feed chute can smoothly discharge raw materials, avoiding the accumulation of raw materials on the operating table and preventing interference with the molding of bricks.

[0013] Preferably, the molding machine has an upper molding cylinder at the top, with an upper molding mold at the bottom of the piston rod of the upper molding cylinder, and a pair of lower molding cylinders at the bottom, with a lower molding mold at the front end of the piston rod of the lower molding cylinder. The two lower molding molds are fitted together at the bottom of the molding cavity, and the two lower molding molds are at different heights within the molding cavity.

[0014] The two lower forming dies provide different filling spaces for the two raw materials, thus allowing for different volumes of raw materials to be fed into the bricks according to different densities and density requirements, thereby enabling the composite double-layer energy-saving material bricks to be pressed and formed with high quality.

[0015] Preferably, during the molding operation, the two lower molding dies are lifted to the same height by the lower molding cylinder.

[0016] This method of operation ensures that no serious gaps or uneven marks are produced at the bottom of the brick during molding, thus ensuring the molding quality of the composite double-layer energy-saving material brick.

[0017] A method for composite molding of building energy-saving materials, utilizing the above-mentioned molding system to mold the energy-saving materials, includes the following specific steps: S1: First, the auxiliary mold cavity and the forming mold cavity are connected, and the partition plate is lowered into the forming mold cavity to complete the partition of the forming mold cavity; S2: Subsequently, material A and material B are fed into the two divided sides of the molding cavity through the two filling chambers of the filling hopper. The feeding is excessive, and both material A and material B overflow into the auxiliary mold cavity. S3: Then the isolation plate rises and detaches from the forming mold cavity, the auxiliary mold cavity is reset, the material inside the forming mold cavity is smoothed out and the excess material is carried away; S4: The composite energy-saving bricks are formed using a molding machine, and the formed energy-saving bricks are then removed.

[0018] Preferably, in step S3, after the material feeding is completed, the molding cavity slides back and forth to completely smooth out the material inside the molding cavity.

[0019] Preferably, in step S4, the top upper forming mold of the molding machine is first pressed into the forming cavity, and then the two bottom lower forming molds extend to make the height of the two bottom lower forming molds the same. Then the upper forming mold repeatedly vibrates and compacts to form the composite energy-saving brick. Then the upper forming mold rises and the lower forming mold continues to rise to lift the composite energy-saving brick onto the operating table for removal.

[0020] Compared with the prior art, the beneficial effects of the present invention are: This invention has a simple structure. Through the cooperation of the filling mechanism and auxiliary mechanism on both sides, it realizes the automated input and pressing of two different materials in composite energy-saving insulation bricks, which improves the automation level and production efficiency of brick production. At the same time, the quantitative input improves the processing quality of bricks.

[0021] The automated filling system of the present invention has a simple and practical structure, is easy to operate, has a fast filling speed, does not occupy the space on the front and back sides of the molding machine, does not interfere with the installation of the brick ejection mechanism, can smoothly form the layout of the production line, and improve the overall automation level of processing.

[0022] Based on the density of different materials, this invention designs a structure with different filler volumes corresponding to different raw materials, which can ensure the overall density and quality of the brick and improve the thermal insulation performance of the brick.

[0025] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application. Example

[0026] As shown in the figure, the building energy-saving material composite molding system of the present invention includes a molding machine 1, which includes a molding frame 11. The molding frame 11 has an operating table 12 for installing molding molds in the middle. The two side support frames of the molding frame 11 are gantry structures, and the tops of the two sides of the molding frame 11 are connected by crossbeams. There is an installation channel between the molding frames 11, which serves as the installation space for the subsequent filling mechanism 3 and auxiliary mechanism 4. The central part of the operating table 12 is the forming cavity 2, which serves as the material filling cavity and also as the forming mold for the brick. An upper forming cylinder 14 is installed on the top of the forming frame 11, and an upper forming mold 15 is installed at the bottom of the piston rod of the upper forming cylinder 14. The upper forming mold 15 corresponds to the forming cavity 2. The bottom of the forming machine 1 has a lower forming cylinder 16, and a lower forming mold 17 is installed at the front end of the piston rod of the lower forming cylinder 16. When forming the brick, the lower forming cylinder 16 and the upper forming cylinder 14 work together to press and form the brick efficiently. After the brick is formed, the lower forming cylinder 16 continuously lifts the formed brick onto the operating table 12, where it is grasped by the gripping mechanism for further transfer.

[0027] An auxiliary mechanism 4 is installed on one side of the molding machine 1, and a filling mechanism 3 is installed on the other side. The filling mechanism 3 includes a filling slide rail 31, a filling cylinder 32, and a filling hopper 33. The filling slide rail 31 is fixedly installed on the molding frame 11. The filling hopper 33 has sliding pairs on both sides that slide with the filling slide rail 31. The end of the filling cylinder 32 is fixed to an extension bracket of the molding machine 1 on that side. The front end of the piston rod of the filling cylinder 32 is fixedly connected to the far end of the filling hopper 33. Through the extension and retraction of the filling cylinder 32, the filling hopper 33 can reciprocate on the filling slide rail 31. The filling hopper 33 has two symmetrically arranged filling chambers 34, which are not connected. The two filling chambers 34 are used to receive two different types of brick materials. Specifically, there is a material guiding mechanism on the upper side of the outer side of the filling mechanism 3. The material guiding mechanism is a weighing bin with two sets of screw feeders or belt feeders. There is a slide valve at the bottom of the weighing bin. After the weighing bin weighs the raw material, the slide valve is opened to release the raw material into the two filling cavities 34 for temporary storage, and then the raw material is transferred to the molding cavity 2 through the filling cavities 34.

[0028] The auxiliary mechanism 4 includes an auxiliary slide rail 41, an auxiliary cylinder 42, and an auxiliary mold cavity 43. The auxiliary slide rail 41 is mounted on the forming frame 11. The auxiliary mold cavity 43 has sliding pairs on both sides that are connected to the auxiliary slide rail 41. The end of the auxiliary cylinder 42 is fixed to the extension bracket of the forming machine 1 on that side. The front end of the piston rod of the auxiliary cylinder 42 is fixedly connected to the far end of the auxiliary mold cavity 43. Through the extension and retraction of the auxiliary cylinder 42, the auxiliary mold cavity 43 can reciprocate and slide on the auxiliary slide rail 41. The bottom surface of the auxiliary mold cavity 43 is in contact with the top surface of the operating table 12. By extending the auxiliary cylinder 42, the auxiliary mold cavity 43 can be moved above the forming mold cavity 2, achieving docking between the forming mold cavity 2 and the auxiliary mold cavity 43. The inner dimensions of the forming mold cavity 2 are adapted to the dimensions of the auxiliary mold cavity 43, and the length of the auxiliary mold cavity 43 is slightly smaller than the length of the forming mold cavity 2, which allows for smooth material introduction.

[0029] In this embodiment, the auxiliary mold cavity 43 has grooves on both sides, and a partition plate 44 is slidably installed in the grooves. The partition plate 44 divides the auxiliary mold cavity 43 into two chambers, which are used to receive the raw materials of the two filling chambers 34 respectively. The gap between the two filling chambers 34 is adapted to the subsequent partition plate 44, so that the filling hopper 33 will not interfere with the partition plate 44. A lifting cylinder 45 is vertically installed on the side of the auxiliary mold cavity 43 near the auxiliary cylinder 42. The top of the piston rod of the lifting cylinder 45 is connected to the top of the partition plate 44. The width of the partition plate 44 is the same as the length of the forming mold cavity 2, and the length of the auxiliary mold cavity 43 is slightly smaller than the length of the forming mold cavity 2. When the lifting cylinder 45 is in the extended state, the partition plate 44 exits the molding cavity 2 and the bottom of the partition plate 44 is coplanar with the bottom surface of the auxiliary cavity 43. When the lifting cylinder 45 is in the retracted state, the partition plate 44 falls into the molding cavity 2 and the bottom of the partition plate 44 contacts the bottom surface of the molding cavity 2, thus dividing the molding cavity 2 into two chambers, which are used to fill two molding materials respectively.

[0030] Specifically, the partition plate 44 can be a flat plate or an irregularly shaped plate. In order to fully improve the combination of the two materials and enhance the thermal insulation performance, the two materials are molded together in an interlocking manner, so the partition plate 44 is a folded plate with multiple concave and convex structures.

[0031] When the filling hopper 33 is filled, two filling chambers 34 are positioned on either side of the partition plate 44, introducing the two materials of the composite double-layer insulation brick into the chambers on either side of the partition plate 44. Specifically, the diameter of the bottom outlet of the filling chamber 34 is less than half the diameter of the top opening of the auxiliary mold cavity 43, thus preventing the raw material from spilling out when introduced into the auxiliary mold cavity 43 and affecting the molding quality. The top of the filling chamber 34 has a conical cavity, with the conical cavity being flat on the side closest to each other. The conical cavity expands the temporary storage space for the raw material and can better receive the raw material released symmetrically from the hopper.

[0032] The filling hopper 33 is used to introduce brick raw materials into the molding cavity 2. A valve plate can be installed at its bottom for restriction, or the raw materials can be blocked and restricted by a contact surface. In this embodiment, a cylinder-controlled slide gate valve is installed at the bottom of each filling cavity 34. The slide gate valve opens outwards. When material needs to be introduced into the auxiliary mold cavity 43, the slide gate valve opens to allow the raw materials to exit. After the raw materials are exited, the slide gate valve closes, forming a closed hopper in the filling cavity 34 for receiving the next batch of raw materials.

[0033] Specifically, the operating table 12, located on one side of the auxiliary mechanism 4, has a pair of guide troughs 13. The guide troughs 13 are connected to inclined slides for discharging raw materials. The diameter of the guide troughs 13 is smaller than the diameter of one side of the auxiliary mold cavity 43 after it is divided. The guide troughs 13 correspond to the two sides of the auxiliary mold cavity 43 divided by the partition plate 44. When the auxiliary mold cavity 43 passes through the guide troughs 13, the raw materials remaining in it fall into the guide troughs 13 and are discharged. The bottom of the guide troughs 13 is connected to a return mechanism. The return mechanism receives excess raw materials and collects them for temporary storage or guides them back to the raw material bin.

[0034] The specific steps for producing composite double-layer material energy-saving bricks using this molding system are as follows: First, the two filling cavities 34 of the filling hopper 33 respectively receive the two weighed materials, which are defined as material A and material B. Then, through the extension action of the auxiliary cylinder 42, the auxiliary mold cavity 43 is connected with the forming mold cavity 2, and the partition plate 44 descends into the forming mold cavity 2 to complete the partition of the forming mold cavity 2.

[0035] Subsequently, the filling cylinder 32 extends, causing the two filling cavities 34 of the filling hopper 33 to align with the two sides of the auxiliary mold cavity 43. Material A and material B are then fed into the divided sides of the molding cavity 2, respectively. The feeding is excessive, and both material A and material B overflow into the auxiliary mold cavity 43. After filling is completed, the filling hopper 33 is reset.

[0036] Furthermore, after the material feeding is completed, the molding cavity 2 slides back and forth to completely smooth out the material inside the molding cavity 2 before resetting.

[0037] Subsequently, the isolation plate 44 rises and detaches from the forming mold cavity 2, the auxiliary mold cavity 43 resets, smooths the material inside the forming mold cavity 2 and removes the excess material.

[0038] Finally, the composite energy-saving bricks are formed using molding machine 1, and the formed energy-saving bricks are then removed. Example

[0039] Regarding Example 1, this embodiment addresses the issue of different densities between two materials by designing a molding device that allows for the feeding of materials A and B at different volumes. Specifically, this embodiment has two lower molding dies 17, each corresponding to a separately controlled lower molding cylinder 16. The two lower molding dies 17 are combined into one unit to seal the bottom of the molding cavity 2. During feeding, the two lower molding dies 17 are positioned at different heights within the molding cavity 2, thus creating different feeding volumes for the two materials.

[0040] In this embodiment, after the partition plate 44 extends into the molding cavity 2, the molding cavity 2 connects with the upper lower molding mold 17, achieving isolation between different material spaces within the molding cavity 2. During the molding operation, the upper molding mold 15 is first pressed into the molding cavity 2. The two lower molding molds 17 are then lifted to the same height by the lower molding cylinder 16, and then the upper molding mold 15 is repeatedly vibrated and compacted to complete the final pressing and molding of the brick. Composite bricks pressed in this way can ensure that the density of the two raw materials is consistent, resulting in higher overall quality of the brick, better service life, and better thermal insulation performance. Example

[0041] For either Embodiment 1 or Embodiment 2, in this embodiment, a gate valve is not installed at the bottom of the filling mechanism 3, reducing this high-failure-rate structure. In this embodiment, a slide 35 is installed below the filling mechanism 3, and the bottom of the filling cavity 34 contacts the slide 35. When the filling hopper 33 slides on the slide 35, the raw material will not fall out. When the auxiliary mold cavity 43 is connected to the forming mold cavity 2, the front end of the slide 35 abuts against the auxiliary mold cavity 43, and the top of the slide 35 is not lower than the height of the auxiliary mold cavity 43. Thus, after the filling hopper 33 continues to extend and detach from the slide 35, the material inside can be released into the auxiliary mold cavity 43.

[0042] More specifically, a sliding cylinder 36 is installed at the bottom of the slide table 35. The sliding cylinder 36 controls the sliding of the slide table 35. When the sliding cylinder 36 extends, the slide table 35 docks with the auxiliary mold cavity 43. When the sliding cylinder 36 retracts, the slide table 35 disengages from the area where the forming mold cavity 2 is located, so as not to interfere with the exit of the brick after forming.
