Description

Technical Field

[0001] The present invention relates to the technical field of building material production equipment, and in particular to a pouring device for the production of prefabricated building materials. Background Art

[0002] A prefabricated building refers to a building in which a large amount of on-site work in the traditional construction method is transferred to the factory. Building components and fittings (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory and transported to the building construction site, and are assembled and installed on-site through reliable connection methods. Prefabricated buildings mainly include precast prefabricated concrete structures, steel structures, modern wood structures, etc. Because of the use of standardized design, factory production, assembly construction, information management, and intelligent application, it is a representative of modern industrial production methods. When pouring prefabricated building materials, a pouring device is needed for pouring. When in use, the pouring device is usually used to directly pour the mixed building materials. After pouring, a vibrator is usually used to continuously vibrate to make there be no gaps between the poured materials. When in use, a layer of pouring material needs to be laid and then continuously replaced, and then laid again. A large amount of time is wasted during the replacement process. During the pouring process, the pouring materials cannot be well distributed and are usually stacked together and then manually divided. The Chinese patent with the authorization announcement number of CN115229959B in the prior art discloses a pouring device for the production of prefabricated building materials, including a pouring frame body, a material guiding frame, and a vibrating column. A feeding hopper for introducing the mixed building materials is arranged at the top of the pouring frame body. A material guiding frame is arranged on one side surface of the pouring frame body. A material guiding pipe is connected to the bottom of the material guiding frame. A pushing member is arranged on the side surface of the pouring frame body far away from the material guiding frame. A moving member that can move along it is arranged at the bottom of the pouring frame body. An adjusting rod is connected to the bottom of the moving member. A vibrating column for contracting it is installed on the adjusting rod. Scale lines are arranged on both the vibrating column and the adjusting rod. A vibrating plate is arranged on the vibrating column.

[0003] When the pouring frame in the above device pours the mixed building materials through the material guide pipe, the poured materials can be vibrated by the vibration column to reduce the gap between the mixed materials and improve the stability of the materials after pouring. However, during use, the vibration of the vibration column can easily cause the entire device to vibrate more violently, and the vibration of the vibration column not only vibrates the material poured in the guide tube, but also transmits the vibration wave to the casting frame through the adjusting rod. Since the adjusting rod and the vibration column are threadedly connected by a threaded disk, the hard contact between the two can easily affect the service life of the casting frame during the continuous vibration process; and the pressure sensor in the above-mentioned device is arranged at the bottom of the vibration column to detect the height of the casting material. First, the pressure sensor is in contact with the casting material for a long time. When used for a long time, it is easy to cause the circuit at the connection of the pressure sensor to be affected by the vibration, so that the pressure sensor cannot work for a long time, and the failure rate is high. After the casting material contacts the surface of the pressure sensor, the pressure sensor needs to be cleaned in time after each use to ensure that the pressure sensor works normally next time. Secondly, the force area of the pressure sensor at the bottom of the vibration column is limited by the diameter of the vibration column. Therefore, when the vibration column contacts the liquid surface of the casting material downward, the pressure signal received by the pressure sensor is relatively weak, and it is difficult to ensure the detection accuracy of the height of the casting material. Summary of the invention

[0004] The embodiment of the present application provides a casting device for the production of prefabricated building materials, which solves the technical problems that when the casting equipment in the prior art is working, the vibration waves have a great impact on the device itself, and the detection accuracy of the pressure sensor is poor, making it difficult to effectively judge the casting height of the casting material. This achieves the technical effect of reducing the shaking of the casting frame caused by the vibration waves and improving the casting accuracy.

[0005] The embodiment of the present application provides a casting device for the production of assembled building materials, including a casting frame, a material guide frame, an angle adjustment member, a transmission adjustment frame, a control system and a vibration shell, wherein the bottom of the material guide frame is connected to a material guide pipe; there are multiple material guide pipes, one end of which is away from the material guide frame and is fixed to one side of the vibration shell; a moving member that can move along its length direction is arranged at the bottom of the casting frame, an adjustment belt is connected to the bottom of the moving member, the adjustment belt is a non-elastic soft belt body, the moving member is moved by the control of the transmission adjustment frame, a vibration shell is installed at the bottom of the adjustment belt, the vibration shell is arranged horizontally, and a vibration plate is fixed to the upper end surface of the vibration shell;

[0006] The top end of the adjusting belt is provided with a winding box. The top of the winding box is fixedly connected to a moving member. A winding motor is fixed on one side of the winding box. The output end of the winding motor is fixedly provided with a winding shaft. The top end of the adjusting belt is fixed on the winding shaft. The bottom end of the adjusting belt is fixedly provided with a tension plate. The vibration shell is a cuboid with a hollow interior. The bottom of the vibration shell is open. A vibration roller is rotatably connected inside the vibration shell through a positioning shaft. The vibration roller is a cylinder as a whole. At both ends of the upper end surface of the vibration shell, a vibration plate is respectively fixed. The upper end surface of the tension plate abuts against the inner top of the vibration shell. A tension sensor is fixed at the connection between the tension plate and the adjusting belt.

[0007] Preferably, the winding shaft penetrates into the interior of the winding box. The winding shaft is horizontally arranged and can rotate self-driven by the winding motor. The length direction of the adjusting belt is perpendicular to the winding shaft. A through groove is opened at the bottom of the winding box. The bottom of the adjusting belt passes through the through groove.

[0008] Preferably, one end of the bottom of the pouring frame body is connected with an angle adjusting member for adjusting its height and angle. The angle adjusting member includes a stable platform fixed on the ground and an angle adjusting column for supporting the pouring frame body. A feeding hopper for introducing the building materials after mixing is arranged at the top of the pouring frame body. A material guiding frame is arranged on one side surface of the pouring frame body. A booster pump for assisting the discharging of the material guiding frame is arranged on one side of the material guiding frame. An electric push rod is arranged on the side surface of the pouring frame body far away from the material guiding frame.

[0009] Preferably, a sliding groove is opened in the middle of the upper end surface of the vibration shell. The sliding groove is a through groove. The bottom of the adjusting belt slides through the sliding groove. The width of the tension plate is greater than that of the sliding groove.

[0010] Preferably, the control system includes a programmable logic controller and a power supply. The electric push rod, the winding motor, the transmission adjusting frame, the booster pump, the vibration plate and the tension sensor are all in signal connection with the control system and are all electrically connected to the power supply.

[0011] Preferably, the vibration roller is a cylindrical barrel with a hollow interior and openings at both ends. The positioning shaft is a horizontally arranged cylindrical rod. Both ends of the positioning shaft are fixed between the two side walls in the length direction inside the vibration shell. The vibration roller is sleeved outside the positioning shaft. The diameter of the vibration roller is greater than that of the positioning shaft.

[0012] Preferably, the lower end surface of the tension plate and the vibration roller are fixedly connected by an elastic tension belt. The elastic tension belt is a belt made of elastic rubber material. On the left and right sides of the upper end of the positioning shaft, a pressure sensor is respectively fixed, and the pressure sensor is signal-connected to the control system. When the lower surface of the vibration roller does not contact the casting material, the vibration roller stretches the elastic tension belt and presses down the pressure sensor under its own gravity. When the lower surface of the vibration roller contacts the casting material, the vibration roller is lifted upward by the casting material, and at the same time, the elastic tension belt contracts, and the tension of the adjusting belt and the elastic tension belt acting on the tension sensor both decrease. When the surface of the casting material is uneven, the pressures applied by the vibration roller on the two pressure sensors deviate, so that the control system determines that the surface of the casting material is inclined, and then controls the vibration roller to level the surface of the casting material.

[0013] Preferably, an elastic capsule is fixedly covered on the inner surface of the vibration roller. The elastic capsule is made of elastic silica gel material. A sealed cavity is formed between the elastic capsule and the vibration roller, and paraffin wax is filled inside the cavity of the elastic capsule. A cylindrical channel is formed in the middle of the elastic capsule, and the diameter of the channel is larger than the diameter of the positioning shaft.

[0014] Preferably, a heating core is coaxially arranged at the center inside the positioning shaft, and the heating core is electrically connected to the control system. When laying the casting material, the paraffin wax is in a solidified state. When casting is completed and the surface of the casting material needs to be leveled, the vibrating plate stops working, and the heating core is heated under the control of the control system, thereby softening the paraffin wax.

[0015] Preferably, a rotating roller is coaxially sleeved outside the positioning shaft. The rotating roller is in the shape of a cylindrical barrel, and the two ends of the rotating roller are open and fixedly sealed with the positioning shaft through elastic rubber sheets. A sealed cavity is formed between the positioning shaft and the inside of the rotating roller, and heat-conducting oil is filled in the cavity. The diameter of the rotating roller is larger than the diameter of the positioning shaft.

[0016] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0017] By setting a soft adjusting belt to cooperate with the winding motor, the control system can obtain the released length of the adjusting belt in real time. Through the cooperation between the vibration shell and the tension plate, the tension sensor can detect the reaction force of the gravity of the vibration shell when it is far from the surface of the casting material, so as to detect the position height of the surface of the casting material by combining the tension change. During the working process, the tension sensor does not directly contact the casting material throughout the process. At the same time, due to the large contact area between the vibration roller and the surface of the casting material, the obtained height information is more reliable. At the same time, during the process of the vibration roller contacting the casting material, it can vibrate the casting material to discharge the bubbles generated in the internal gaps of the casting material, resulting in higher product quality, and the cast product is more dense and reliable. And when the vibration roller moves to the next position, it can level the surface of the casting material. At the same time, the side of the vibration shell can be bound to more guide pipes, enabling the guide frame to release more casting materials simultaneously, greatly improving the casting efficiency. In summary, the embodiment of the present application solves the technical problems that in the existing casting equipment, the vibration wave has a greater impact on the device itself, and at the same time, the detection accuracy of the pressure sensor is poor, making it difficult to effectively judge the casting height of the casting material, and realizes the technical effect of being able to reduce the shaking influence of the vibration wave on the casting frame and improve the casting accuracy at the same time.

Detailed implementation mode

[0027] To facilitate the understanding of the present invention, the present application will be described more comprehensively below with reference to the relevant drawings; the preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein; on the contrary, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs; the terms used in the description of the present invention in this specification are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0030] Example 1: As Figure 1 and Figure 2As shown in the figure, a casting device for the production of prefabricated building materials according to the present application includes a casting frame body, a material guiding frame 200, an angle adjusting member, a transmission adjusting frame 300, a control system, and a vibration housing 700. One end of the bottom of the casting frame body is connected to an angle adjusting member for adjusting its height and angle. The angle adjusting member includes a stable platform 500 fixed to the ground and an angle adjusting column 400 for supporting the casting frame body. A feeding hopper 110 for introducing the building materials after mixing is provided at the top of the casting frame body. A material guiding frame 200 is provided on one side of the casting frame body. A booster pump 210 for assisting the discharge of the material guiding frame 200 is provided on one side of the material guiding frame 200. The bottom of the material guiding frame 200 is communicated with a material guiding pipe 220. There are multiple material guiding pipes 220, and one end of the material guiding pipe 220 away from the material guiding frame 200 is fixed to one side of the vibration housing 700. An electric push rod 120 is provided on the side of the casting frame body away from the material guiding frame 200. A moving member that can move along the length direction of the casting frame body is provided at the bottom of the casting frame body. The bottom of the moving member is connected to an adjusting belt 600. The adjusting belt 600 is a non-elastic soft belt body. The moving member moves under the control of the transmission adjusting frame 300. The vibration housing 700 is installed at the bottom of the adjusting belt 600. The vibration housing 700 is horizontally arranged, and a vibration plate 710 is fixed on the upper end surface of the vibration housing 700.

[0031] A winding box 620 is provided at the top end of the adjusting belt 600. The top of the winding box 620 is fixedly connected to the moving member. A winding motor 630 is fixed on one side of the winding box 620. The output end of the winding motor 630 is fixed with a winding shaft 631. The winding shaft 631 penetrates into the interior of the winding box 620. The winding shaft 631 is horizontally arranged. The winding shaft 631 can rotate self-driven by the winding motor 630. The top end of the adjusting belt 600 is fixed on the winding shaft 631. The length direction of the adjusting belt 600 is perpendicular to the winding shaft 631. The winding motor 630 is a servo motor. By controlling the rotation of the winding shaft 631 by the winding motor 630, the winding and unwinding length of the adjusting belt 600 can be obtained in real time, so as to obtain the overall height position of the vibration housing 700. A through groove is opened at the bottom of the winding box 620, and the bottom of the adjusting belt 600 passes through the through groove. A tension plate 610 is fixed at the bottom of the adjusting belt 600. The vibration housing 700 is a cuboid with a hollow interior. The bottom of the vibration housing 700 is open. A vibration roller 720 is rotatably connected to the interior of the vibration housing 700 through a positioning shaft 730. The vibration roller 720 is a cylinder as a whole. A vibration plate 710 is fixed at each end of the upper end surface of the vibration housing 700. A sliding groove is opened in the middle of the upper end surface of the vibration housing 700. The sliding groove is a through groove. The bottom of the adjusting belt 600 slides through the sliding groove. The width of the tension plate 610 is greater than the sliding groove. The upper end surface of the tension plate 610 abuts against the inner top of the vibration housing 700. A tension sensor 611 is fixed at the connection between the tension plate 610 and the adjusting belt 600.

[0032] The control system includes a programmable logic controller and a power supply. The electric push rod 120, the winding motor 630, the transmission adjusting frame 300, the booster pump 210, the vibrating plate 710, and the tension sensor 611 are all signal-connected to the control system and are all electrically connected to the power supply.

[0033] Under the working state, the gravity of the whole vibrating shell 700 acts on the tension plate 610, so that the tension applied to the tension sensor 611 through the adjusting belt 600 is the gravity of the vibrating shell 700, and the tension value detected by the tension sensor 611 is uploaded to the control system; the winding motor 630 controls the winding and unwinding length of the adjusting belt 600 to make the vibrating roller 720 contact the surface of the casting material below. When the vibrating roller 720 contacts the casting material, due to the surface tension thereof, an upward thrust is exerted on the vibrating roller 720, so that the tension received by the tension sensor 611 is reduced, and thus the tension value uploaded by the tension sensor 611 to the control system changes. When the tension change value reaches the set threshold, the control system determines that the vibrating roller 720 contacts the casting material at this moment. The control system calculates the length of the adjusting belt 600 released through the rotation information of the winding motor 630, and thus controls the vibrating shell 700 to move to the next position through the moving member and the adjusting belt 600. At the same time, the vibrating roller 720 levels the surface of the casting material during the movement.

[0034] The technical solutions in the embodiments of the present application at least have the following technical effects or advantages:

[0035] In this embodiment, by providing a flexible adjustment belt 600 in cooperation with the winding motor 630, the control system can obtain the released length of the adjustment belt 600 in real time. Through the cooperation between the vibration housing 700 and the tension plate 610, when the tension sensor 611 is away from the surface of the casting material, it can detect the reaction force of the gravity of the vibration housing 700, so as to detect the position height of the casting material surface by combining the tension change. During the working process, the tension sensor 611 does not directly contact the casting material throughout the process. At the same time, due to the large contact area between the vibration roller 720 and the casting material surface, the obtained height information is more reliable. At the same time, during the contact process between the vibration roller 720 and the casting material, the casting material can be vibrated to discharge the bubbles generated in the internal gaps of the casting material, resulting in higher quality of the finished product, and the cast finished product is more dense and reliable. And when the vibration roller 720 moves to the next position, it can level the surface of the casting material. At the same time, more guide pipes 220 can be bound to the side surface of the vibration housing 700, so that the guide frame 200 can release more casting materials at the same time, greatly improving the casting efficiency. To sum up, the embodiment of the present application solves the technical problems that in the existing casting equipment during operation, the vibration wave has a greater impact on the device itself, and at the same time, the detection accuracy of the pressure sensor 731 is poor, making it difficult to effectively judge the casting height of the casting material, and realizes the technical effect of being able to reduce the shaking influence of the vibration wave on the casting frame body and at the same time improve the casting accuracy.

[0036] Embodiment 2: Considering that in the above Embodiment 1, the vibration housing 700 and the adjustment belt 600 are movably connected through the tension plate 610, and the vibration housing 700 has a certain length and is horizontally arranged. Since the surface of the casting material below the vibration housing 700 is uneven, it may cause the heights of both ends to be inconsistent after the vibration roller 720 contacts the casting material surface, resulting in a deviation in the tension value fed back to the tension sensor 611. It is necessary to level the surface of the casting material below first. Therefore, the device needs to be improved, such as Figure 3 shown, and the specific structure is as follows:

[0037] The lower end surface of the tension plate 610 is fixedly connected to the vibration roller 720 through an elastic tension belt 721. The elastic tension belt 721 is a belt body made of elastic rubber material. The vibration roller 720 is a cylindrical tube with a hollow interior and both ends open. The positioning shaft 730 is a horizontally arranged cylindrical rod. Both ends of the positioning shaft 730 are fixed between the two side walls in the length direction inside the vibration housing 700. The vibration roller 720 is sleeved outside the positioning shaft 730, and the diameter of the vibration roller 720 is larger than the diameter of the positioning shaft 730. A pressure sensor 731 is respectively fixed on the left and right sides of the upper end of the positioning shaft 730, and the pressure sensor 731 is signal-connected to the control system.

[0038] When the lower surface of the vibrating roller 720 does not contact the casting material, the vibrating roller 720 stretches the elastic tension belt 721 under its own gravity and presses down the pressure sensor 731; when the lower surface of the vibrating roller 720 contacts the casting material, the vibrating roller 720 is lifted upward by the casting material, and at the same time the elastic tension belt 721 contracts, and the pulling forces acting on the adjusting belt 600 of the tension sensor 611 and the elastic tension belt 721 both decrease; when the surface of the casting material is uneven, the pressures applied by the vibrating roller 720 on the two pressure sensors 731 deviate, so that the control system determines that the surface of the casting material is inclined, and then controls the vibrating roller 720 to level the surface of the casting material.

[0039] The technical solutions in the above embodiments of the present application at least have the following technical effects or advantages:

[0040] In this embodiment, by arranging the hollow vibrating roller 720 to cooperate with the pressure sensor 731 and the tension sensor 611, the change in the pulling force received by the tension sensor 611 is more significant. At the same time, when the vibrating roller 720 is inclined, the unevenness of the surface of the casting material is judged by the pressure sensor 731, so as to correct the surface of the casting material, reduce the error of the tension sensor 611, and improve the detection accuracy of the height of the laid casting material.

[0041] Embodiment 3: Considering that in the above Embodiment 2, since the cast material needs to change from a fluid state to a solid state after casting, but the change process is slow, resulting in slow forming of the casting material and low efficiency. Secondly, during the process of the vibrating roller 720 leveling the casting material, due to the vibration of the vibrating plate 710, there are many vibration afterwaves, which easily affect the shape of the surface of the casting material during leveling. Therefore, the device needs to be improved, such as Figure 4 and Figure 5 shown, the specific structure is as follows:

[0042] The inner surface of the vibrating roller 720 is covered and fixed with an elastic capsule 722. The elastic capsule 722 is made of elastic silicone material. A sealed cavity is formed between the elastic capsule 722 and the vibrating roller 720, and paraffin 723 is filled inside the cavity of the elastic capsule 722. A cylindrical channel is formed in the middle of the elastic capsule 722, and the diameter of the channel is larger than the diameter of the positioning shaft 730; a heating core 732 is coaxially arranged at the center inside the positioning shaft 730, and the heating core 732 is electrically connected to the control system.

[0043] When laying the casting material, the paraffin wax 723 is in a solidified state. The vibrating plate 710 vibrates to drive the positioning shaft 730, and the positioning shaft 730 conducts vibration waves to the elastic capsule 722 and the paraffin wax 723, so that the vibrating roller 720 vibrates the surface of the casting material to eliminate air bubbles inside the material. When the casting is completed and the surface of the casting material needs to be leveled, the vibrating plate 710 stops working, and the heating core 732 heats under the control of the control system, thereby softening the paraffin wax 723, enabling the paraffin wax 723 to absorb the residual vibration waves, and causing the paraffin wax 723 to concentrate at the inner bottom of the vibrating roller 720 after forming a liquid state, making the rolling of the vibrating roller 720 more stable.

[0044] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0045] In this embodiment, by setting the elastic capsule 722 and the heating core 732, and filling paraffin wax 723 in the elastic capsule 722, the two states of the paraffin wax 723 are controlled by the heating core 732. When the casting material needs to be vibrated, the paraffin wax 723 remains in a solid state, making the hard contact between the elastic capsule 722 and the positioning shaft 730, and better conducting vibration waves. When the leveling work is required, the heating core 732 softens the paraffin wax 723, uses the softened paraffin wax 723 to absorb the residual vibration waves, and at the same time makes the paraffin wax 723 concentrate at the inner bottom of the vibrating roller 720 and flow as the vibrating roller 720 rotates. The center of gravity of the vibrating roller 720 always remains at a lower point, so that the vibrating roller 720 can better level the casting material.

[0046] Embodiment 4: Considering that the contact between the positioning shaft 730 and the elastic capsule 722 in the above Embodiment 3 is restricted by the pressure sensor 731, and since the elastic capsule 722 is soft, the friction is large after the surface contacts the edges and corners of the pressure sensor 731, which easily affects the rolling of the vibrating roller 720. Secondly, it is easy to affect the heat conduction effect between the heating core 732 and the paraffin wax 723. Therefore, the device needs to be improved, such as Figure 6 and Figure 7 shown, the specific structure is as follows:

[0047] A roller 740 is coaxially sleeved outside the positioning shaft 730. The roller 740 is in the shape of a cylindrical tube. Both ends of the roller 740 are open and are fixedly sealed with the positioning shaft 730 through elastic rubber sheets. A closed cavity is formed between the positioning shaft 730 and the inside of the roller 740, and heat-conducting oil 741 is filled in the cavity. The diameter of the roller 740 is larger than the diameter of the positioning shaft 730. Preferably, the roller 740 is made of a metal material with good heat conductivity.

[0048] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0049] In this embodiment, by setting the rotating roller 740 and the heat-conducting oil 741, when the vibrating roller 720 performs the leveling work, the heating core 732 is heated, and the heat is conducted to the surface of the rotating roller 740 through the heat-conducting oil 741. Since the surface of the rotating roller 740 is smooth, the heat of the rotating roller 740 can be better transferred to the paraffin 723 when the vibrating roller 720 rotates, so that the paraffin 723 is quickly softened.

[0050] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
