Description

Technical Field

[0001] This invention belongs to the field of mortar material forming technology, specifically, it relates to a mortar material conveying and forming device. Background Technology

[0002] In the field of precast component molding, the quality of mortar material conveying and molding directly determines the structural strength and service life of the components. The industry's demand for efficient venting, precise material replenishment, and continuous production is becoming increasingly urgent. Traditional mortar material conveying and molding devices have several technical defects in practical applications: poor mortar spreading uniformity requires additional manual labor or special equipment for leveling, which can easily lead to localized material caking and waste; at the same time, existing technologies mostly use venting methods that apply pressure to collapse the air cavities inside the blank, which is difficult to vent and has unstable effects, making it difficult to completely eliminate internal air bubbles, ultimately leading to quality problems such as hollowness and insufficient strength in the components, affecting their performance.

[0003] Furthermore, a search revealed that although the mortar material conveying and molding device scheme of Chinese Patent Publication No. CN116922543B achieves molding operation through leveling, rolling, and replenishment mechanisms, it still has significant technical defects. In this scheme, the amount of filler in the replenishment mechanism is directly affected by the number of air chambers. When the exhaust is incomplete or there are few air chambers, the amount of filler will decrease or even stop, resulting in insufficient fluidity of mortar in the replenishment channel, drying and caking, which in turn leads to blockage and material waste, affecting the efficiency of continuous production and the stability of molding quality.

[0004] However, although the mortar material conveying and molding device scheme of Chinese Patent Publication No. CN119734346B adopts the design of forced venting and synchronous feeding with ejector pins and has a complete structure including a conveying unit, a leveling mechanism, a rolling mechanism and a replenishment mechanism, it still has significant defects. In this scheme, the ejector pins need to be directly inserted into the pressurized mortar blank to vent, which can easily cause disturbance to the blank structure. Moreover, it can only treat the blank in the molding stage and cannot reduce the air entrained during mortar injection from the source. At the same time, this scheme lacks pre-treatment methods such as mold preheating and vacuum environment assistance. When the mortar viscosity is high, the filling efficiency is low. It is especially unsuitable for the molding requirements of thin-walled, irregularly shaped and other complex cavity components, which limits its application scope and production efficiency.

[0008] Preferably, in order to eliminate air from the mold cavity and gaps and reduce the source of air bubbles formed when mortar is injected, the vacuum assembly includes a vertical plate set on the moving plate, a vacuum generator set on the side wall of the vertical plate, a connecting pipe set at the output end of the vacuum generator, and the connecting pipe connected to the side wall of the vertical plate through a support column.

[0009] Preferably, to facilitate connection and use, ensure sealing during grouting and vacuuming, and facilitate subsequent separation without affecting the continued delivery of the mold, the connecting pipe and the vacuuming pipe, as well as the discharge pipe and the pouring port, are connected by a sealing assembly. The sealing assembly includes a plug ring at the end of the connecting pipe and the discharge pipe, and a plug groove at the end of the vacuuming pipe and the pouring port. The connecting pipe and the vacuuming pipe, as well as the discharge pipe and the pouring port, are connected by the plug ring and the plug groove. Sealing rings are evenly spaced inside the plug ring, and a sealing groove with an interference fit to the sealing ring is opened on the outer circumferential side of the plug groove. Valves are provided on both the pouring port and the vacuuming pipe.

[0010] Preferably, in order to facilitate the connection and separation of the discharge pipe and the pouring port, a first electric push rod is symmetrically arranged under the storage tank.

The telescopic tube is located between the plug ring and the discharge pipe.

[0011] Preferably, in order to allow the movable plate to move back and forth, thereby facilitating the positioning of the positioning block and the positioning groove, clamping the mold, and facilitating the connection and positioning between the vacuum device and the vacuum tube, the adjustment component includes adjustment grooves symmetrically opened on both sides of the processing table. A slider is set in the adjustment groove through a second electric push rod. The slider slides back and forth in the adjustment groove, and the tops of the two sliders on the same side are fixedly connected to the movable plate.

[0012] Preferably, in order to assist in vibration and tapping during the grouting process, assist in material feeding, and eliminate air bubbles, the tapping mechanism includes a motor mounted on a movable plate, a crankshaft fixedly mounted at the output end of the motor, the end of the crankshaft being connected to the movable plate through a bearing seat, a collar being fitted on the crankshaft, and a tapping component matching the mold being provided on the side wall of the collar.

[0013] Preferably, in order to assist in vibration and tapping during the grouting process, assist in material feeding, and eliminate air bubbles, the tapping assembly includes a rotating part connected to the side wall of the collar, a tapping column is fixedly provided at the end of the rotating part, a sliding hole is provided on the vertical plate for the tapping column to slide back and forth horizontally in the sliding hole, and a shim is also provided on the end face of the tapping column near the mold.

[0014] Preferably, in order to facilitate the positioning and fixing of the mold, facilitate the connection and assembly of each component with the mold, and ensure stability during grouting and vibration hammering, a positioning block is provided on the side wall of the vertical plate near the mold, and splicing blocks are provided on both side walls of the upper and lower molds. Two splicing blocks in the same vertical direction are spliced ​​to form a rectangular block, and a positioning groove matching the positioning block is opened in the rectangular block.

[0015] Compared with the prior art, the advantages of the present invention include: (1) The mortar material conveying and molding device provided by the present invention has a pre-treatment optimization level. The mold adopts an openable structure and integrates a heating device. The mold cavity is preheated by the heating device inside the cavity, which effectively reduces the viscosity of the mortar material and improves its fluidity. This solves the problem of low filling efficiency caused by high mortar viscosity in traditional technology. It is especially suitable for the molding needs of complex cavity components such as thin-walled and irregular shapes, while avoiding material caking and waste. (2) The mortar material conveying and molding device provided by the present invention, in terms of exhaust and molding quality control, the vacuum component is directly connected to the mold cavity through the vacuum tube. Before the mortar is injected, the mold cavity and gaps are vacuumed to directly remove the trapped air and reduce the source of air bubbles. Combined with the vibration and hammering function of the hammering mechanism, the hammering column is driven by the crankshaft to reciprocate during the grouting process, which helps the mortar to flow and fill in the complex cavity and break up the tiny air bubbles, effectively solving the quality problems such as hollowness and insufficient strength caused by incomplete exhaust in the traditional technology. (3) The present invention provides a mortar material conveying and molding device. The device achieves precise reciprocating movement of the moving plate through the adjustment component. It is positioned by the positioning block and the positioning groove on the mold splicing block to ensure the precise and reliable connection of the grouting, vacuuming and hammering processes. The sealing component forms a reliable seal between the discharge pipe and the pouring port, and between the connecting pipe and the vacuum pipe through the interference fit of the insertion ring and the insertion groove and the design of multiple sealing rings. With the valve control, it not only ensures the sealing effect during grouting and vacuuming, but also facilitates connection and separation without affecting the mold conveying. Thus, it realizes the integrated design of "pretreatment-molding-trimming" and takes into account both production efficiency and molding accuracy. Attached Figure Description

[0025] Furthermore, to provide the public with a better understanding of the present invention, certain specific details are described in detail in the following description of the invention. However, those skilled in the art will fully understand the invention even without these detailed descriptions.

[0026] Please see Figures 1-7A mortar material conveying and molding device includes a processing table 11, on which a conveying device 12 is provided. This device can be a conveyor belt or conveyor roller, etc., to facilitate the conveying of mortar molding molds. A mold for mortar molding is placed on the conveying device 12. The mold has a cavity 18 inside, and a pouring port 16 matching the cavity 18 is provided at its top. The mold includes a lower mold 13 and an upper mold 14. Mounting plates 24 are provided on the peripheral sides of both the lower mold 13 and the upper mold 14. Two mounting plates 24 in the same vertical direction are fixedly connected by bolts 25. A sealing device is provided between the upper mold 14 and the lower mold 13 to ensure the sealing effect of the cavity 18 after mold closing. This is a relatively mature technology and will not be elaborated upon here. Furthermore, both the lower mold 13 and the upper mold 14 have cavities inside, and heating devices 19 matching the cavity 18 are provided within these cavities. The heating device 19 can be... Electric heating can also be achieved using heat transfer oil or other methods. This allows the mold to be preheated before the mortar is injected into the mold cavity 18, reducing the viscosity of the mortar and accelerating its fluidity. The heating temperature is 40-60℃, which can be selected according to the type and condition of the mortar. This is a relatively mature technology and will not be elaborated here. A storage tank 15 is provided on the processing table 11, and a discharge pipe 17 matching the pouring port 16 is provided under the storage tank 15. The storage tank 15 is only partially shown in the figure. It is used to temporarily store the mortar to be injected. In order to ensure the grouting effect, a stirring device can be provided inside the storage tank 15, which can be composed of a motor, a rotating shaft, and stirring blades, etc. This facilitates the mixing of the mortar before injection and avoids stratification. This is a relatively mature technology and will not be elaborated here. Movable plates 44 are provided on both sides of the processing table 11 through adjustment components. A knocking mechanism is provided on the movable plates 44, and a vacuum component is also provided on the movable plates 44.

[0027] Please see Figures 1-7 In order to perform vacuuming before mortar injection, the vacuum environment can cause the air bubbles in the mortar to expand and burst, reducing the curing shrinkage rate. Vacuum can also reduce interfacial tension, making the mortar and mold fit more tightly and improving the molding accuracy. The vacuuming component includes a vertical plate 53 set on the moving plate 44. A vacuum generator 54 is set on the side wall of the vertical plate 53. A connecting pipe 52 is set at the output end of the vacuum generator 54. The connecting pipe 52 is connected to the side wall of the vertical plate 53 through a support column 55. The support column 55 can ensure the stability of the connecting pipe 52. The top of the mold is equipped with a vacuuming pipe 51 that matches the vacuuming component. The vacuuming pipe 51 is connected to the mold cavity 18, which facilitates vacuuming before the vacuuming component is used. The vacuum degree can be -0.08 to -0.095 MPa, which can directly remove air from the mold cavity and gaps, reducing the source of air bubbles formed when the mortar is injected. For mold sealing, high-temperature resistant silicone rubber sealing rings 32, with a temperature resistance of ≥150℃, are suitable for mold heating temperatures of 45-60℃. They should fit the mold parting surface with a thickness of 3-5mm to prevent aging and leakage after heating. A vacuum pressure gauge and anti-backflow valve should be installed on the vacuum tube 51 to prevent air backflow when the pump stops. One or two vacuum sensors can be attached inside the mold cavity 18 to monitor the vacuum level in real time. If the mold is thin-walled or has a complex cavity, such as with grooves or holes, an additional vacuum interface should be reserved deep inside the cavity to avoid the formation of "air dead zones". The vacuuming time can be appropriately extended by 2-3 minutes to ensure that the air in the dead zones is completely discharged. The vacuum level should not be too high, not exceeding -0.1MPa, especially for molds made of plastic or thin steel plates, as excessive vacuum may cause the cavity to sink and deform. It is recommended to set an "upper limit of vacuum" according to the material strength during mold design and to set an alarm threshold in the control system, such as automatic shutdown when the vacuum level is <-0.1MPa. This is a relatively mature technology and will not be elaborated here.

[0028] Please see Figures 1-7 To ensure a proper seal during mortar injection and vacuuming without affecting the connection, the connecting pipe 52 and vacuum pipe 51, as well as the outlet pipe 17 and pouring port 16, are connected by sealing components. These sealing components include insertion rings 31 at the ends of the connecting pipe 52 and outlet pipe 17, and insertion grooves 33 at the ends of the vacuum pipe 51 and pouring port 16. The connecting pipe 52 and vacuum pipe 51, and the outlet pipe 17 and pouring port 16, are connected by insertion rings 31 and insertion grooves 33. Sealing rings 32 are evenly spaced within the insertion rings 31, and sealing grooves 34, which are press-fitted to the sealing rings 32, are formed on the outer periphery of the insertion grooves 33. The number of sealing rings 32 and sealing grooves 34 can be two, three, or other sets, with two sets being preferred to ensure a proper seal during connection and to avoid affecting mortar injection and vacuuming operations. The pouring port 16... Both the vacuum tube 51 and the vacuum tube 51 are equipped with valves 35, which can be electrically controlled valves for easy opening and closing without affecting mortar injection and vacuuming. They can also be closed after operation. The storage tank 15 is symmetrically equipped with the first electric push rod 21. The output end of the first electric push rod 21 is fixedly equipped with a lifting plate 22. The middle of the lifting plate 22 is equipped with a telescopic tube 23. The telescopic tube 23 is located between the insertion ring 31 and the discharge pipe 17. When the conveying device 12 transports the mold to the bottom of the storage tank 15, the first electric push rod 21 can extend and retract, moving the discharge pipe 17 up and down. It works with the insertion ring 31 and the insertion groove 33 to complete the connection and separation of the discharge pipe 17 and the pouring port 16, which facilitates the injection and separation of mortar without affecting subsequent conveying. The telescopic tube 23 can extend and retract with the first electric push rod 21 for easy insertion without affecting the flow of mortar.

[0029] Please see Figures 1-7To facilitate positioning and fixation during mortar injection, and to assist in vibration and tapping to accelerate the flow of mortar within the mold, especially in complex cavities, and to break up and expel tiny air bubbles inside the mortar, such as those introduced during stirring, the vibration frequency can be 20-40Hz, or other suitable frequencies can be selected according to actual conditions. The adjustment component includes symmetrical adjustment grooves 41 on both sides of the processing table 11. Slider 43 is installed in the adjustment grooves 41 via a second electric push rod 42. The slider 43 slides back and forth within the adjustment grooves 41, and the tops of the two sliders 43 on the same side are fixed to the moving plate 44. The fixed connection is achieved by extending and retracting the second electric push rod 42, which allows the slider 43 to reciprocate within the adjustment groove 41, thereby moving and adjusting the movable plate 44. The striking mechanism includes a motor 45 mounted on the movable plate 44, with a crankshaft 46 fixedly mounted at the output end of the motor 45. The end of the crankshaft 46 is connected to the movable plate 44 via a bearing seat. A collar 71 is fitted onto the crankshaft 46. The number of collars 71 on the crankshaft 46 can be two sets to ensure uniform striking vibration. Other numbers, such as one or three sets, can also be set according to actual conditions. The sidewall of the collar 71 is provided with striking components that match the mold. The component includes a rotating part 72 connected to the side wall of the collar 71. A striking post 73 is fixedly installed at the end of the rotating part 72. A sliding hole 75 is provided on the vertical plate 53 for the striking post 73 to slide horizontally back and forth within the sliding hole 75. A shim 74 is also provided on the end face of the striking post 73 near the mold. The shim 74 can be made of elastic material such as rubber to avoid hard contact with the side wall of the mold. The striking position of the striking post 73 is located in the mold cavity 18 of the lower mold 13 to ensure the effect of striking vibration. It can also be set in other positions according to the actual situation to facilitate positioning before mortar injection and connection. During grouting and hammering, positioning and fixing are performed to prevent displacement. Positioning blocks 61 are provided on the side wall of the vertical plate 53 near the mold. Splicing blocks 62 are provided on both side walls of the upper mold 14 and the lower mold 13. Two splicing blocks 62 in the same vertical direction are spliced ​​to form a rectangular block. The rectangular block has a positioning groove 63 that matches the positioning block 61. By cooperating with the positioning blocks 61 on both sides and the positioning groove 63, the mold as a whole can be clamped and positioned, which facilitates the connection between the discharge pipe 17 and the pouring port 16, the vacuum pipe 51 and the connecting pipe 52, and at the same time, positioning and fixing are performed during grouting and hammering.

[0030] During the mortar molding process, the specific procedures for heating, vacuuming, and vibration are as follows: After the mold is installed and positioned, start heating and vacuuming simultaneously to avoid wasting time by operating in separate steps. The heating temperature for ordinary cement mortar should be controlled at 45-55℃, while for special mortars such as waterproofing and anti-corrosion mortars, it can be increased to 60℃. The vacuum degree should be stabilized at -0.08 to -0.095 MPa for 5-8 minutes, adjusted according to the mold volume; the larger the volume, the longer the time. After pretreatment, confirm that the mold temperature and vacuum degree meet the standards using sensors for real-time display, then start the mortar injection pump and simultaneously turn on the vibration device. The vibration frequency should be 25-40Hz; for thin-walled molds, select 25-30Hz to avoid mold resonance; for thick-walled molds, select 30-40Hz to enhance mortar fluidity. The injection speed should be controlled at 60-100L / min, adjusted according to the mold inlet size; a slower speed for smaller inlets prevents mortar splashing.

[0031] Working principle: The upper mold 14 and lower mold 13 are assembled and fixed by bolts 25 on the mounting plate 24. Then, the mold is placed on the conveying device 12. The conveying device 12 works to transport the mold. When the mold reaches the pouring station, the conveying stops. At this time, the second electric push rod 42 extends and slides the slider 43 in the adjusting groove 41. The moving plate 44 moves towards the mold. At this time, the positioning block 61 contacts the positioning groove 63 to complete the insertion positioning. During the contact positioning process, the insertion ring 31 at the end of the connecting pipe 52 inserts into the insertion groove 33 of the vacuum pipe 51. The sealing ring 32 and the sealing groove 34 complete the insertion sealing. The striking column 73 moves to the striking position. At this time, the heating device 19 and the vacuum generator 54 work to heat the mold cavity 18 and evacuate the air. After the operation is completed, the first electric push rod 21 extends and lifts the lifting plate. 22 moves downward, and the telescopic pipe 23 under the discharge pipe 17 extends, inserting into the insertion groove 33 through the insertion ring 31. With the cooperation of the sealing ring 32 and the sealing groove 34, the insertion and sealing of the discharge pipe 17 and the pouring port 16 are completed. Then, the mortar in the storage tank 15 can be injected into the mold cavity 18. During the injection process, the motor 45 works, driving the crankshaft 46 to rotate. With the cooperation of the collar 71 and the rotating part 72, the striking column 73 can move back and forth in the sliding hole 75. With the cooperation of the gasket 74, the mold can be vibrated and struck. After the grouting is completed, the valve 35 is closed. The discharge pipe 17, the connecting pipe 52 and the positioning block 61 can be separated away from the mold by the retraction and reset of the first electric push rod 21 and the second electric push rod 42. Then, the conveying device 12 continues to work, which can transport the grouted mold to the subsequent station for cooling and shaping operations. The above operations are repeated to achieve continuous conveying and shaping of mortar materials.

[0032] It should be understood that the above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It should not be considered that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the protection scope of the present invention.
