The present invention extends the extended ejector pin into the pressurized mortar blank. If there is an air cavity, the pressurized mortar blank will force the air to be discharged from the ejector pin to avoid the air being dispersed inside the mortar blank, ensuring efficient and stable exhaust.

Description

Technical Field

[0001] The invention relates to the technical field of prefabricated component forming and processing, in particular to a mortar material conveying and forming device. Background Art

[0002] During the production and preparation of precast concrete parts, the prepared concrete needs to be introduced into the conveying equipment. However, it is difficult to achieve uniform laying of the concrete when it falls on the material. It needs to be spread and leveled manually or with additional equipment, and excess material needs to be collected. Otherwise, the accumulated material will easily become compacted, resulting in material waste.

[0003] It is difficult for existing conveying equipment to eliminate the air cavity inside the concrete after the distribution is completed. The publication number is CN116922543B, and the patent name is Mortar Material Conveying and Molding Device, which discloses a technical solution that shapes the concrete material through a flat material mechanism, a rolling mechanism, and a supplementary mechanism in sequence.

[0004] This method of feeding is to apply pressure to collapse the air cavities and hollow parts inside the blank, thereby exhausting the air and avoiding hollowing. This method of exhaust is difficult to exhaust. If the exhaust fails or there are fewer air cavities, the filling material replenished by the replenishing mechanism each time is less or not replenished. Therefore, the concrete material in the replenishing mechanism lacks fluidity and is easily dried and hardened, which causes the channel for conveying materials to be blocked and material waste. Summary of the invention

When the top pressure plate turns up again, the conveyor belt moves, so that the mortar blank that has been filled, trimmed and shaped moves out of the top pressure plate.

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] The existing material replenishment method is to apply pressure to collapse the air cavity and hollow part inside the blank, thereby exhausting the air and avoiding hollowing. This exhaust method is difficult to exhaust. If the exhaust fails or the air cavity is small, the filling material replenished by the replenishing mechanism each time is small or not replenished. Therefore, the concrete material in the replenishing mechanism lacks fluidity and is easy to dry and harden, thereby causing the channel for conveying materials to be blocked and material waste.

[0042] See attached Figure 1-8 As shown, Figure 1 It is a schematic diagram of the overall structure of a mortar material conveying and molding device; Figure 2 It is a top view of a mortar material conveying and molding device; Figure 3 for Figure 2 Sectional view at AA in the middle; Figure 4 It is a side view of a mortar material conveying and molding device; Figure 5 It is a schematic diagram of the overall structure of a feeding mechanism in a mortar material conveying and molding device; Figure 6 It is a bottom view of a feeding mechanism in a mortar material conveying and molding device; Figure 7 It is a structural schematic diagram of a mortar material conveying and molding device in one embodiment; Figure 8 It is a structural schematic diagram of a forced exhaust component in a mortar material conveying and molding device.

[0043] In order to solve the above technical problems, a mortar material conveying and molding device is provided, comprising: a conveying mechanism 100 and a feeding mechanism 200.

[0044] Among them, the conveying mechanism 100 is used to transport mortar raw materials; the feeding mechanism 200 is used to simultaneously force the exhaust of the passing blanks, fill the cavities formed after the exhaust, and trim and shape the inside and outside of the blanks.

[0045] See attached Figure 3 As shown, Figure 3 for Figure 2 In the cross-sectional view taken at AA, the conveying mechanism 100 includes: a conveyor belt body 110, a frame assembly 120 and a driving unit.

[0046] The conveyor belt body 110 and the driving part are both arranged on the frame assembly 120, and the driving part and the conveyor belt body 110 are used for material transportation.

[0047] Preferably, the driving part is a transmission assembly composed of a motor, a reducer and a transmission assembly. When working, the motor and the reducer transmission assembly drive the conveyor belt body 110 to move to achieve cyclic transportation. The frame assembly 120 includes a roller, a roller, a tensioning device, a main bracket, an auxiliary bracket, a crossbeam, a connecting component, and a protective component to achieve the functions it needs to achieve. Since the transmission mechanism 100 is not improved in this solution, it will not be repeated.

[0048] This solution focuses on improving the feeding mechanism 200. When the conveying mechanism 100 transports the mortar material to the feeding mechanism 200, the mortar raw material has been basically shaped, and the cross section is basically consistent with the concrete prefabricated part to be prepared. Therefore, the main functions of the feeding mechanism 200 are: to simultaneously force the exhaust of the passing blank, fill the cavity formed after the exhaust, and trim and shape the inside and outside of the blank. The exhaust, filling, trimming and shaping are achieved in the shortest possible distance, which reduces the length of the production line and improves the quality of the feeding.

[0049] See attached Figure 1 , 3 As shown, Figure 1 It is a schematic diagram of the overall structure of a mortar material conveying and molding device; Figure 3 for Figure 2 Cross-sectional view at AA in the middle.

[0050] In order to facilitate understanding of the technical solution of the present application, the feeding mechanism 200 is further explained.

[0051] The feeding mechanism 200 includes: a reciprocating lifting assembly 210, a rotating connection assembly 220, a pressing plate assembly 230, a forced exhaust assembly 240, and a filling assembly 250.

[0052] Among them, one end of the pressing plate assembly 230 is connected to the top surface of the frame assembly 120 through the rotating connection assembly 220, and the forced exhaust assembly 240 and the filling assembly 250 are both installed on the pressing plate assembly 230.

[0053] The reciprocating lifting assembly 210 is located at the material inlet end of the pressing plate assembly 230 , and the forced exhaust assembly 240 and the filling assembly 250 are arranged in sequence on the top surface of the pressing plate assembly 230 along the material conveying direction.

[0054] Specifically, the mortar material passes through the pressing plate assembly 230, and the reciprocating lifting assembly 210 is used to continuously lift and press the pressing plate assembly 230 to extrude the concrete stock. When the pressing plate assembly 230 is pressed down, the forced exhaust assembly 240 performs forced exhaust, and when the pressing plate assembly 230 is lifted, the filling assembly 250 performs mortar material filling. When the pressing plate assembly 230 is pressed down again, the filled mortar material is pressed into the concrete stock, and the exhaust and filling are completed. After that, the concrete stock that has been shaped is moved out of the pressing plate assembly 230 under the drive of the conveyor belt body 110. In this way, the exhaust and filling of the concrete stock can be achieved, and all operations can be completed within a very short distance.

[0055] Since the exhaust process is forced, each time the filling assembly 250 is filled with a certain amount of stuff, the delivery pipeline is always in a flowing state and is extremely difficult to be blocked.

[0056] See attached Figure 5 As shown, Figure 5 It is a schematic diagram of the overall structure of a feeding mechanism in a mortar material conveying and molding device.

[0057] To facilitate understanding of the technical solution of the present application, further description is given to the pressing plate assembly 230. The pressing plate assembly 230 continuously applies pressure to shape the mortar blank over a certain length.

[0058] The pressure plate assembly 230 includes: a top pressure plate 231 , a side pressure plate 232 , a first connecting ear 234 , and a second connecting ear 235 .

[0059] Among them, the side pressure plate 232 is located at the bottom edge of both sides of the top pressure plate 231 and is perpendicular to the bottom surface of the top pressure plate 231. The side pressure plate 232 has a protruding connecting ear 234 at the position corresponding to the rotating connecting component 220, and the top surface of the top pressure plate 231 has a connecting ear 235 corresponding to the position of the reciprocating lifting component 210. The side pressure plate 232 is in an arc shape at the position corresponding to the connecting ear 234.

[0060] Specifically, the side pressure plate 232 and the top pressure plate 231 form an inverted U-shaped structure in cross section, forming a square shape with the top surface of the conveyor belt body 110. The top pressure plate 231 and the side pressure plate 232 rotate around the virtual axis where the center positions of the two connecting ears 234 are located, and the connecting ear 235 provided on the top surface of the top pressure plate 231 is to facilitate the reciprocating lifting assembly 210 to act on the top pressure plate 231, so that it turns up and down around the rotating connecting assembly 220.

[0061] In this embodiment, there are two first connecting ears 234 , and there are several second connecting ears 235 , such as three, which are evenly distributed on the top surface of the top pressure plate 231 .

[0062] Preferably, the side pressure plate 232 is longer than the top pressure plate 231, and is arranged in an arc shape at the position corresponding to the connecting ear 234 to prevent the side pressure plate 232 from interfering with the top surface of the conveyor belt body 110 during rotation.

[0063] Preferably, the top pressure plate 231 and the side pressure plate 232 are made of stainless steel. The top pressure plate 231 and the side pressure plate 232 are formed by integral stamping or welding. When the side pressure plate 232 is not turned up, it contacts the top surface of the conveyor belt body 110 to prevent the mortar blank from overflowing from between the side pressure plate 232 and the conveyor belt body 110 when the top pressure plate 231 is pressed on the mortar blank.

[0064] See attached Figure 7 As shown, Figure 7 1 is a schematic diagram of the structure of a mortar material conveying and forming device in one embodiment. In order to further optimize the smoothing of the surface of the mortar blank when the top pressure plate 231 is turned up and the mortar blank moves, a reversible smoothing component a can be provided at the edge of the discharge end of the top pressure plate 231.

[0065] Specifically, the smoothing component a is turned over to keep it horizontal when the top pressure plate 231 is turned up. When the mortar blank moves, the surface of the mortar blank can be smoothed by the smoothing component a.

[0066] It should be noted that the smoothing component a can be composed of the existing wiping plate, pushing mechanism, and rotating link to form the functional structure to be realized. Technical personnel in this field can also use the existing wiping plate, pushing mechanism, and rotating link to form a structure or component that realizes the above functions. Therefore, the specific structure of the smoothing component a is clear, and it is not a protection point in this case, so it will not be elaborated on.

[0067] Preferably, the rotating connection seat 212 is fixed to both sides of the frame assembly 120 by a bolt structure. The second connection ear 235 and the top pressure plate 231 are welded as a whole.

[0068] See attached Figure 5 As shown, Figure 5It is a schematic diagram of the overall structure of a feeding mechanism in a mortar material conveying and molding device.

[0069] In order to facilitate understanding of the technical solution of the present application, the reciprocating jacking assembly 210 is further explained.

[0070] The reciprocating lifting assembly 210 includes a hydraulic jack 211 , a rotating connection seat 212 and a rotating connection shaft 213 .

[0071] Among them, the rotating connecting seat 212 is fixed to both sides of the frame assembly 120 respectively, the bottom end of the hydraulic push rod 211 is rotatably connected to the rotating connecting seat 212, and the top end is connected to the end of the rotating connecting shaft 213, and the rotating connecting shaft 213 passes through a plurality of connecting ears 235.

[0072] Since a large force is required to apply pressure to the mortar blank, a hydraulic push rod 211 is used to ensure that sufficient pressure can be applied to the mortar blank. The bottom end of the hydraulic push rod 211 is connected to the rotating connection seat 212, and the top end is connected to the pressure plate assembly 230 through the rotating connection shaft 213, ensuring that the hydraulic push rod 211 can adjust its posture when it is extended or shortened, so that the hydraulic push rod 211 works more stably and smoothly.

[0073] Preferably, the rotating connecting shaft 213 passes through a plurality of connecting ears 235 and is rotatably connected to the connecting ears 235. During operation, the hydraulic push rod 211 is extended, and as the pressing plate assembly 230 is turned over, the inclination angle of the hydraulic push rod 211 changes accordingly, so that the bottom end of the hydraulic push rod 211 rotates around the rotating connecting seat 212, and the top end drives the rotating connecting shaft 213 and the connecting ears 235 to rotate. The extension and shortening of the hydraulic push rod 211 enables the pressing plate assembly 230 to achieve reciprocating upward and downward pressing actions. When the pressing plate assembly 230 is turned up, the mortar raw materials are replenished, and when the pressing plate assembly 230 is pressed down, the filler is replenished and the exhaust is achieved.

[0074] In the actual production process, the stroke of the hydraulic push rod 211 is controllable, and travel switches are set at both ends of the stroke to realize the working state control of the hydraulic push rod 211. If necessary, the action interval is controlled by a delay switch to ensure sufficient exhaust and filling.

[0075] See attached Figure 5 As shown, Figure 5 It is a schematic diagram of the overall structure of a feeding mechanism in a mortar material conveying and molding device.

[0076] In this embodiment, the rotating connection assembly 220 includes a base 221 and a rotating shaft assembly 222 .

[0077] Preferably, the base 221 is an L-shaped structure and is symmetrically distributed on both sides of the frame assembly 120. The base 221 is rotatably connected to the connecting ear 234 through the rotating shaft assembly 222.

[0078] The structure of the base 221 is similar to that of the rotating connection base 212 , and the base 221 is fixed to both sides of the frame assembly 120 by means of a bolt structure.

[0079] Preferably, the shaft assembly 222 includes a bearing and a shaft, one end of the shaft is rotatably connected to the base 221 through the bearing, and the other end is directly connected to the corresponding connecting ear 234, so that when the pressure plate assembly 230 is turned upside down, it rotates around the shaft. Of course, the shaft assembly 222 can also adopt other structures to realize the rotatable connection between the pressure plate assembly 230 and the base 221, and is not limited to the above structure.

[0080] See also Figure 3 , 5 , 6, Figure 3 for Figure 2 Sectional view at AA in the middle; Figure 5 It is a schematic diagram of the overall structure of a feeding mechanism in a mortar material conveying and molding device; Figure 6 It is a bottom view of a feeding mechanism in a mortar material conveying and molding device.

[0081] In order to facilitate understanding of the technical solution of the present application, a specific implementation of the forced exhaust component 240 is provided.

[0082] The forced exhaust assembly 240 includes a cylinder 241 and a ejector pin 242 .

[0083] The cylinders 241 are arranged in a rectangular shape on the top surface of the top pressure plate 231 and close to the material input end. The top ends of the cylinders 241 are connected to the high-pressure control pipeline, and the top ends of the ejector pins 242 are located in the cylinders 241 to form a piston structure.

[0084] In normal state, the interior of the cylinder 241 is under negative pressure, the ejector pin 242 is located in the cylinder 241 , and the bottom end thereof does not exceed the bottom surface of the ejector plate 231 .

[0085] During operation, the interior of the cylinder 241 is under high pressure, the ejector pin 242 completely extends out of the cylinder 241 , and the bottom end does not exceed the bottom end of the side pressure plate 232 .

[0086] Specifically, the normal state is that the top pressure plate 231 is in the upturned state, including the top pressure plate 231 starting to turn up until it turns up to the maximum angle. The working state is that the hydraulic push rod 211 is in the minimum stroke position, the top pressure plate 231 presses on the mortar blank, and the ejector pin 242 extends. The extended ejector pin 242 extends into the pressurized mortar blank. If there is an air cavity, the pressurized mortar blank will force the air to be discharged from the ejector pin 242, avoiding the air from being dispersed inside the mortar blank, and ensuring efficient and stable exhaust.

[0087] When the push plate 231 is turned up, the ejector pin 242 is retracted into the cylinder 241 in advance, and the concave position formed by the exhaust air cavity will move to the position of the filling component 250 after the push plate 231 is turned up.

[0088] See attached Figure 8 As shown, Figure 8 It is a structural schematic diagram of a forced exhaust component in a mortar material conveying and molding device.

[0089] The top of the cylinder 241 has an air inlet port 241a connected to the high-pressure air supply pipeline, and the bottom of the cylinder 241 has a mounting plate 241b connected to the top surface of the top pressure plate 231, and the bottom surface of the mounting plate 241b has a cleaning sleeve 241c sleeved on the needle rod of the ejector pin 242.

[0090] In addition, the top end of the ejector pin 242 located inside the cylinder 241 is configured as a piston structure 242a. Therefore, when the air pressure inside the cylinder 241 changes, the piston mechanism 242a will move up and down inside the cylinder 241, that is, when the pressure inside the cylinder 241 increases, the piston structure 242a is moved downward by the high-pressure air, pushing the ejector pin 242 out; when the pressure inside the cylinder 241 decreases, the piston structure 242a is affected by negative pressure, and the external air pushes the piston structure 242a to move toward the inside of the cylinder 241.

[0091] In addition, in order to prevent the mortar raw materials from being brought into the cylinder 241 during each insertion and extraction process of the ejector pin 242 , the ejector pin 242 is cleaned by the cleaning sleeve 241 c to prevent the mortar raw materials from entering the cylinder 241 .

[0092] See attached Figure 1 , 3 As shown in Figure 4, in order to facilitate the understanding of the technical solution of the present application, a specific implementation of the filling component 250 is provided.

[0093] The filling assembly 250 includes: a diffusion cover 251 and a control valve 252 .

[0094] Among them, the discharge port at the bottom end of the expansion cover 251 corresponds to the groove 236 corresponding to the top surface of the top pressure plate 231, the control valve 252 is connected to the expansion cover 251, and the feed end of the control valve 252 is connected to the feeding assembly.

[0095] Specifically, the notch 236 is perpendicular to the incoming material direction, and the length of the notch 236 is consistent with the width of the top pressure plate 231. The expansion cover 251 is a flat funnel-shaped structure, the feed port is located at the top, and the opening cross section is smaller than the discharge port cross section.

[0096] When the top pressure plate 231 turns up, the control valve 252 opens, so that the mortar raw material passes through the control valve 252, the expansion cover 251 and the notch 236 in sequence, and finally falls on the surface of the mortar blank after the ejector pin 242 exhausts. When the top pressure plate 231 starts to press down, the control valve 252 is closed. As the top pressure plate 231 continues to press down, the side pressure plate 232 is cooperated to complete the filling, trimming and shaping of the mortar blank after exhausting. When the top pressure plate 231 turns up again, the conveyor belt body 110 moves, so that the mortar blank after filling, trimming and shaping moves out of the top pressure plate 231.

[0097] Preferably, the distance that the conveying mechanism 100 moves each time is the center distance between the filling assembly 250 and the forced exhaust assembly 240, which is hereinafter referred to as a unit distance. That is, the distance that the conveyor belt body 110 moves each time is the center distance between the filling assembly 250 and the forced exhaust assembly 240. It is ensured that each time the filling of the filling assembly 250 can cover the surface of the mortar blank after exhaust.

[0098] When the conveying mechanism 100 is in motion, the reciprocating lifting assembly 210 is lifted, so that the pressure plate assembly 230 is turned upward around the rotating connecting assembly 220, the filling assembly 250 is filled, and the forced exhaust assembly 240 is retracted before the pressure plate assembly 230 is turned over.

[0099] When the conveying mechanism 100 stops, the reciprocating lifting assembly 210 contracts, so that the pressing plate assembly 230 is pressed downward around the rotating connecting assembly 220, the filling assembly 250 is closed, and the forced exhaust assembly 240 is ejected after the pressing plate assembly 230 stops.

[0100] In order to facilitate the understanding of the specific exhaust and filling process, the specific action process is given as follows:

[0101] Phase 1:

[0102] The top pressure plate 231 turns up. Before the turning up action starts, the ejector pin 242 is retracted into the cylinder 241, and then the hydraulic ejector rod 211 is extended until it reaches the maximum stroke length. At this time, the top pressure plate 231 reaches the maximum turning up angle. When the top pressure plate 231 turns up, the control valve 252 is opened, and the mortar raw material passes through the control valve 252, the expansion cover 251 and the notch 236 in sequence, and finally falls on the surface of the mortar blank after the ejector pin 242 is exhausted. At this time, the conveyor belt body 110 stops after moving the mortar blank for a unit distance.

[0103] Phase 2:

[0104] The push plate 231 is pressed down, and before the downward pressing action begins, the control valve 252 is closed to stop the delivery of the mortar raw material. The hydraulic push rod 211 is retracted until it is retracted to the minimum stroke length. When the hydraulic push rod 211 is retracted to the minimum stroke length, the ejector pin 242 is completely ejected by the cylinder 241.

[0105] During operation, stage one and stage two are cycled alternately.

[0106] The above embodiments are only used to illustrate the technical solutions of the present invention, but not to limit them. Anyone familiar with the technology can modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
