Description

Technical Field

[0001] The invention relates to the technical field of gypsum board production, in particular to a gypsum board forming device. Background Art

[0002] As is known, gypsum board is a material made of building gypsum as the main raw material. It is a building material with light weight, high strength, thin thickness, easy processing, and good sound insulation, heat insulation and fire resistance. When gypsum board is produced, gypsum slurry is sprayed on special paper (the paper used to make gypsum board is special thick board paper) by a machine, and then the gypsum slurry and the thick board paper are squeezed together by an extrusion molding piece to form the prototype of the gypsum board, and then the extruded gypsum board is cut, and then the cut gypsum board is dried to solidify the gypsum board to obtain a finished gypsum board.

[0003] For example, a patent application with publication number CN119057900A and publication date December 3, 2024 and entitled "A rapid pressure forming device for gypsum board" discloses a rapid pressure forming device for gypsum board, which relates to the field of gypsum board forming technology, including a base, a mounting frame fixedly connected to the upper end of the base, a rotating shaft rotatably connected to the inner wall of the mounting frame, and a mirror roller fixedly connected to the side wall of the rotating shaft; a cleaning mechanism, the cleaning mechanism comprising a trapezoidal box fixedly connected to the side wall of the mounting frame through a bracket, a material collection seat fixedly connected to the lower end of the trapezoidal box, a plurality of spline sleeves rotatably connected to the inner wall of the trapezoidal box, a spline shaft slidably connected to the inner wall of the spline shaft, and a striking head fixedly connected to the side wall of the spline shaft. In the present invention, the pulp lumps on the surface of the mirror roller are broken and dropped by the knocking head, and then are sucked out through the suction holes, so that the pulp lumps on the surface of the mirror roller are cleaned to prevent the pulp lumps from affecting the surface of the gypsum board. Compared with scraping with a scraper, there is no need to directly contact the surface of the mirror roller, and the mirror roller will not be worn, thereby improving the service life of the mirror roller.

[0004] The shortcoming of the prior art is that, in the process of the extrusion molding part squeezing the gypsum slurry onto the thick cardboard, the gypsum slurry is easy to flow out from the side edges of the extrusion molding part and the side edges of the thick cardboard when the extrusion molding part squeezes the gypsum slurry, thereby causing waste of gypsum slurry. The solution in the prior art is to bend the side edges on both sides of the thick cardboard to form a concave surface in the middle of the thick cardboard, so that the gypsum slurry will not flow out from the side edges of the thick cardboard. However, the thick cardboard will have a crease after passing through the extrusion molding part, so that there will be edges on the side edges of the gypsum board, which has a negative impact on the quality and appearance of the gypsum board. Summary of the invention

[0005] The purpose of the present invention is to provide a gypsum board forming device to solve the technical problems in the related art.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a gypsum board forming device, comprising a conveying system for conveying thick cardboard, the conveying system is provided with a slurry delivery system for pumping gypsum slurry onto the thick cardboard, the conveying system is also provided with an inverted U-shaped frame, an extrusion molding part is rotatably arranged on the U-shaped frame, and also includes a leak-proof mechanism, the leak-proof mechanism includes a baffle, two straight plates are symmetrically arranged on the U-shaped frame, and each of the two straight plates is provided with a reciprocating baffle, and the gypsum slurry between the thick cardboard and the extrusion molding part is blocked and pushed by the reciprocating baffle.

[0007] As mentioned above, the extrusion molding member is an extrusion roller or an extrusion plate.

[0008] As mentioned above, the conveying system includes a mounting plate and conveying rollers. The mounting plate is two symmetrical plates. A plurality of conveying rollers for conveying thick cardboard are installed in parallel and rotated between the two mounting plates. A synchronous wheel is connected to the end of each conveying roller, and each of the synchronous wheels is driven by a synchronous belt.

[0009] As mentioned above, the slurry delivery system includes a slurry delivery pipe body, and an auxiliary plate is commonly connected to the two mounting plates, and the slurry delivery pipe body is arranged on the auxiliary plate, and the slurry delivery pipe body is connected to a slurry pump.

[0010] As mentioned above, the leakage prevention mechanism also includes a sliding rod, each of the two straight plates is provided with a sliding hole, a sliding rod is slidably arranged in each of the two sliding holes, one end of the two sliding rods is connected to the baffle, and the other end of the two sliding rods is connected to a T-shaped rod.

[0011] As mentioned above, the two baffles are adapted to the gap between the thick paper and the extruded molding member.

[0012] As mentioned above, a driving shaft is arranged on the U-shaped frame, and an extruded plastic part is arranged on the driving shaft between the inner walls of the U-shaped frame. Both ends of the driving shaft pass through the U-shaped frame and are connected to a driving disc. An active groove is respectively provided on the two active discs, and the two T-shaped rods are slidably arranged in the corresponding active grooves.

[0013] As mentioned above, the active groove is a T-shaped annular groove body, in which an arc convex portion is arranged along the axial direction of the extruded plastic part, and the center of the arc convex portion is the same as the center of the annular groove body.

[0014] As mentioned above, the cross section of the annular groove body is a T-shaped structure, and the T-shaped rod is slidably arranged in the active groove, so that the T-shaped rod and the T-shaped structure of the cross section of the annular groove body are slidably arranged relative to each other.

[0015] As mentioned above, a driving member is arranged on the mounting plate, and the output end of the driving member is connected to one of the active discs.

[0016] The beneficial effect of the present invention is that when the gypsum slurry needs to be extruded and formed, the gypsum slurry is driven to move to the position of the extrusion molding part by the thick cardboard, the extrusion molding part is driven to rotate, and the gypsum slurry between the extrusion molding part and the thick cardboard is extruded by the rotating extrusion molding part. Due to the flow of the gypsum slurry on the thick cardboard and the gypsum slurry on the thick cardboard being blocked by the extrusion molding part, the gypsum slurry will still accumulate on the thick cardboard at the position of the extrusion molding part, and the gypsum slurry accumulated on the thick cardboard may flow out from the thick cardboard. The gypsum slurry is pushed from the edge of the thick cardboard to the middle of the thick cardboard by the baffle, so that the gypsum slurry on the thick cardboard will not flow out from the edge of the thick cardboard. Since the thick cardboard can be arranged horizontally, the creases after the finished product are eliminated. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to enable those skilled in the art to better understand the technical solution of the present invention, Figure 1 To Attachment Fig.18 The present invention is further described in detail.

[0039] An embodiment provided by the present invention relates to a gypsum board forming device, including a conveying system for conveying thick cardboard 5, the conveying system is provided with a slurry delivery system for pumping gypsum slurry onto the thick cardboard 5, the conveying system is also provided with an inverted U-shaped frame 1, an extrusion molding part 2 is rotatably arranged on the U-shaped frame 1, and also includes a leakage prevention mechanism, the leakage prevention mechanism includes a baffle 3, two straight plates 4 are symmetrically arranged on the U-shaped frame 1, and a reciprocating baffle 3 is respectively arranged on the two straight plates 4, and the gypsum slurry between the thick cardboard 5 and the extrusion molding part 2 is blocked and pushed by the reciprocating baffle 3.

[0040] Specifically, the gypsum board forming device is a device for extruding and forming gypsum slurry on thick cardboard paper 5 by extruding a shaping member 2. A driving shaft 14 is provided on the U-shaped frame 1. An extruding shaping member 2 is provided on the driving shaft 14 between the inner walls of the U-shaped frame 1. The conveying system is a device for conveying thick cardboard paper 5. The thick cardboard paper 5 is a paper for supporting and protecting the gypsum slurry. The thickness of the thick cardboard paper 5 is large and has a certain bearing capacity. The gypsum slurry can be formed after drying on the thick cardboard paper 5. The conveying system includes a mounting plate 6 and a conveying roller 7. The mounting plate 6 is two mutually symmetrical plate bodies. A plurality of conveying rollers 7 for conveying thick cardboard paper 5 are installed in parallel and rotated between the two mounting plates 6. A synchronous wheel is connected to the end of each conveying roller 7. The synchronous wheels are driven by a synchronous belt. The synchronous belt drives each synchronous wheel to rotate synchronously. Each synchronous wheel drives the conveying roller 7 to rotate synchronously, so that the conveying roller 7 conveys the thick cardboard paper 5. It is common knowledge in the art to convey the thick cardboard paper 5 by the conveying roller 7 and will not be repeated. The slurry delivery system is a device for transporting gypsum slurry. The slurry delivery system includes a slurry delivery pipe body 8. An auxiliary plate 9 is commonly connected to two mounting plates 6. The auxiliary plate 9 is provided with a slurry delivery pipe body 8. The slurry delivery pipe body 8 is connected to a slurry pump 10. The gypsum slurry is transported to the slurry delivery pipe body 8 through the slurry pump 10. Then, the gypsum slurry in the slurry delivery pipe body 8 is sprayed on the thick board paper 5. Transporting gypsum slurry is common knowledge in the art and will not be elaborated on.When the extrusion shaping member 2 is an extrusion roller, the extrusion shaping member 2 is arranged on the downstream part of the slurry feeding pipe body 8 on the conveying system, and is used to roll the upper surface of the gypsum slurry on the thick board paper 5 to roll the uneven upper surface into a flat surface. The baffle 3 is located on the side of the extrusion shaping member 2 close to the slurry feeding pipe body 8. The two baffles 3 are mutually adapted to the gap between the thick board paper 5 and the extrusion shaping member 2. The gypsum slurry moves synchronously with the thick board paper 5. The thick board paper 5 drives the gypsum slurry to move to the position of the extrusion shaping member 2, driving the extrusion shaping member 2 to rotate, and the gypsum slurry between the extrusion shaping member 2 and the thick board paper 5 is squeezed by the rotating extrusion shaping member 2. Industry, since the gypsum slurry moves from the slurry delivery pipe body 8 to one end of the extrusion molding member 2, and since the gap between the extrusion molding member 2 and the thick paper board 5 becomes smaller, the gypsum slurry on the thick paper board 5 accumulates at the position of the extrusion molding member 2. Obviously, the amount of gypsum slurry conveyed by the slurry delivery pipe body 8 per unit time is constant; in the same time period, the flow rate of gypsum slurry extruded through the gap between the extrusion molding member 2 and the thick paper board 5 is also relatively constant. In the same time period, the amount of gypsum slurry conveyed by the slurry delivery pipe body 8 is the same as the flow rate of gypsum slurry extruded through the gap between the extrusion molding member 2 and the thick paper board 5. The gypsum slurry will not accumulate on the thick paperboard 5 at the position of the extrusion molding part 2. However, due to the flow of the gypsum slurry on the thick paperboard 5 and the gypsum slurry on the thick paperboard 5 being blocked by the extrusion molding part 2, the gypsum slurry will still accumulate on the thick paperboard 5 at the position of the extrusion molding part 2. The gypsum slurry accumulated on the thick paperboard 5 will move along the surface of the extrusion molding part 2 and then flow out from both sides of the width direction of the thick paperboard 5. In this embodiment, since the baffle 3 is located on the side of the extrusion molding part 2 close to the slurry feeding pipe body 8, the baffle 3 is in the shape of a plate, and its bottom end is attached to the thick paperboard 5, and the two baffles 3 are both in contact with the thick paperboard 5 and the extrusion molding part The gaps between the parts 2 are adapted to each other, and a sliding seal is set between the bottom end of the baffle 3 and the upper surface of the thick paperboard 5. When the thick paperboard 5 transports the gypsum slurry to the bottom end position of the extrusion molding part 2, when the gypsum slurry on the thick paperboard 5 accumulates at the position of the extrusion molding part 2, the baffle 3 blocks the gypsum slurry to prevent the gypsum slurry from flowing out from the side of the thick paperboard 5. Synchronously, the baffle 3 is driven to perform a linear reciprocating motion, so that the baffle 3 pushes the gypsum slurry, and pushes the gypsum slurry from the edge of the thick paperboard 5 to the middle of the thick paperboard 5 through the baffle 3, so that the gypsum slurry on the thick paperboard 5 will not flow out from the edge of the thick paperboard 5.

[0041] The shortcoming of the prior art is that, in the process of the extrusion molding part 2 squeezing the gypsum slurry onto the thick cardboard 5, the gypsum slurry is easy to flow out from the side edges of the extrusion molding part 2 and the side edges of the thick cardboard 5 when the extrusion molding part 2 squeezes the gypsum slurry, thereby causing a waste of gypsum slurry. The solution in the prior art is to bend the side edges on both sides of the thick cardboard 5 so that a concave surface is formed in the middle of the thick cardboard 5, so that the gypsum slurry will not flow out from the side edges of the thick cardboard 5. However, the thick cardboard 5 will have a crease after passing through the extrusion molding part 2, so that there will be edges on the side edges of the gypsum board, which has a negative impact on the quality and appearance of the gypsum board.

[0042] The beneficial effect of this embodiment is that when the gypsum slurry needs to be extruded and formed, the gypsum slurry is driven to move to the position of the extrusion molding member 2 by the thick cardboard 5, and the extrusion molding member 2 is driven to rotate. The gypsum slurry between the extrusion molding member 2 and the thick cardboard 5 is extruded by the rotating extrusion molding member 2. Due to the flow of the gypsum slurry on the thick cardboard 5 and the gypsum slurry on the thick cardboard 5 being blocked by the extrusion molding member 2, the gypsum slurry will still accumulate on the thick cardboard 5 at the position of the extrusion molding member 2, and the gypsum slurry accumulated on the thick cardboard 5 may flow out from the thick cardboard 5. The gypsum slurry is pushed from the edge of the thick cardboard 5 to the middle of the thick cardboard 5 by the baffle 3, so that the gypsum slurry on the thick cardboard 5 will not flow out from the edge of the thick cardboard 5. Since the thick cardboard 5 can be arranged horizontally, the creases after the finished product are eliminated.

[0043] like Fig.17 and Fig.18As shown, when the extrusion molding member 2 is an extrusion plate, the extrusion molding member 2 is arranged on the downstream part of the slurry delivery pipe body 8 on the conveying system, and is used to extrude the upper surface of the gypsum slurry on the thick paperboard 5 to roll the uneven upper surface into a flat surface. The baffle 3 is located on the side of the extrusion molding member 2 close to the slurry delivery pipe body 8. The two baffles 3 are mutually adapted to the gap between the thick paperboard 5 and the extrusion molding member 2. The gypsum slurry moves synchronously with the thick paperboard 5, and the thick paperboard 5 drives the gypsum slurry to move to the position of the extrusion molding member 2. Since the extrusion molding member 2 is slidably arranged between the inner walls of the U-shaped frame 1, the extrusion molding member 2 and the U-shaped frame 1 are formed by a uniformly arranged elastic body. 44 is connected, and a pushing roller 45 is arranged on the driving shaft 14, and the pushing roller 45 is eccentrically mounted on the driving shaft 14. When the extrusion molding part 2 needs to extrude the gypsum slurry, the driving shaft 14 is driven to rotate, and the driving shaft 14 drives the pushing roller 45 to rotate. Since the pushing roller 45 is eccentrically mounted on the driving shaft 14, the pushing roller 45 can push the extrusion molding part 2 to move toward one end of the gypsum slurry, so that the extrusion molding part 2 performs an extrusion molding operation on the gypsum slurry. At the same time, the extrusion molding part 2 performs an extrusion operation on the elastic body 44 (the elastic body 44 is a component that can be retracted and reset, preferably a spring), so that the elastic body 44 is in a compression state. The extrusion molding part 2 is in a contracted state. After the extrusion molding part 2 extrude the gypsum slurry, the driving shaft 14 continues to drive the pushing roller 45 to rotate. Under the rebound effect of the elastic body 44, the extrusion molding part 2 and the gypsum slurry are separated from each other. This is repeated. The extrusion molding part 2 can perform reciprocating linear motion to realize the extrusion molding part 2 to continuously extrude the gypsum slurry. It is known to those skilled in the art that the rotation of the driving shaft 14 can drive the extrusion molding part 2 to perform linear reciprocating motion to realize the extrusion molding part 2 to extrude the gypsum slurry. A cam is provided on the driving shaft 14, and a cam groove is provided on the cam. A follower is provided on the extrusion molding part 2. The moving part is slidably arranged in the cam groove, and the cam groove is driven to rotate by the rotation of the cam, so that the cam can drive the extrusion molding part 2 to perform linear reciprocating motion through the follower, thereby realizing the extrusion molding operation of the extrusion molding part 2 on the gypsum slurry. There are other methods in the art that drive the extrusion molding part 2 to perform linear reciprocating motion by the rotation of the driving shaft 14, thereby realizing the extrusion molding operation of the extrusion molding part 2 on the gypsum slurry, and the gypsum slurry is pushed from the edge of the thick paper 5 to the middle of the thick paper 5 through the baffle 3, so that the gypsum slurry on the thick paper 5 will not flow out from the edge of the thick paper 5, and since the thick paper board 5 can be arranged horizontally, the crease after the finished product is eliminated.

[0044] In another embodiment provided by the present invention, the leakage prevention mechanism further includes a sliding rod 11, each of the two straight plates 4 is provided with a sliding hole 12, each of the two sliding holes 12 is slidably provided with a sliding rod 11, one end of the two sliding rods 11 is connected to the baffle 3, and the other end of the two sliding rods 11 is respectively connected with a T-shaped rod 13; both ends of the driving shaft 14 pass through the U-shaped frame 1 and are connected with an active disc 15, each of the two active discs 15 is provided with an annular active groove 16, and the two T-shaped rods 13 are slidably provided in the active groove 16 corresponding thereto; the active groove 16 is an annular groove body 17 with a T-shaped cross section, and an arc convex portion 18 is arranged in the annular groove body 17 along the axial direction of the extruded plastic part 2 so that a convex section with a gradual depth is formed in the annular groove body 17, and the center of the arc convex portion 18 is the same as the center of the annular groove body 17; the cross section of the annular groove body 17 is a T-shaped structure, and the T-shaped rod 13 is slidably arranged in the active groove 16, so that the T-shaped rod 13 and the T-shaped structure of the cross section of the annular groove body 17 are slidably arranged with each other; a driving member 19 is arranged on the mounting plate 6, and the output end of the driving member 19 is connected to one of the active discs 15.

[0045] Specifically, when it is necessary to drive the extrusion shaping member 2 to rotate and extrude the gypsum slurry between the extrusion shaping member 2 and the thick paper 5 through the rotating extrusion shaping member 2, the driving member 19 is started (the driving member 19 is a device that can reciprocate at the output end, preferably a motor) to drive the active disc 15 to rotate, the active disc 15 drives the active shaft 14 to rotate, and the active shaft 14 drives the extrusion shaping member 2 to rotate, so that the extrusion shaping member 2 extrude the gypsum slurry on the thick paper 5. Synchronously, since the active disc 15 is provided with an active groove 16, the active groove 16 is driven by the active groove 16. During the process of the disk 15 rotating one circle, the T-shaped rod 13 slides along the track of the active groove 16. When the T-shaped rod 13 slides along the track of the annular groove body 17 of the active groove 16, the positions of the T-shaped rod 13 and the sliding rod 11 in the sliding hole 12 will not change. When the T-shaped rod 13 slides from the annular groove body 17 to the arc convex part 18, since the convex part of the arc convex part 18 faces one end of the U-shaped frame 1, the T-shaped rod slides along the track of the arc convex part 18. Since the sliding hole 12 slides and positions the sliding rod 11, the arc convex part 18 pushes the T-shaped rod 13. The T-shaped rod 13 slides toward one end of the U-shaped frame 1, and the sliding rod 11 slides in the sliding hole 12 toward one end of the U-shaped frame 1. The sliding rod 11 drives the baffle 3 to slide toward one end of the U-shaped frame 1 (that is, the sliding rod 11 drives the baffle 3 to slide from the edge of the thick paper 5 to the middle of the thick paper 5), so that the baffle 3 pushes the gypsum slurry from the edge of the thick paper 5 to the middle of the thick paper 5, so that the gypsum slurry on the thick paper 5 will not flow out from the edge of the thick paper 5, thereby improving the utilization rate of the gypsum slurry. Then, the T-shaped rod 13 slides from the arc protrusion 18 into the annular groove body 17 , so that the T-shaped rod 13 slides from the raised position of the arc convex portion 18 to the annular groove body 17, and the T-shaped rod 13 is pulled by the arc convex portion 18 and the annular groove body 17, so that the T-shaped rod 13 slides away from the end of the U-shaped frame 1, and the T-shaped frame drives the sliding rod 11 to slide in the sliding hole 12 away from the end of the U-shaped frame 1, and the sliding rod 11 drives the baffle 3 to slide away from the end of the U-shaped frame 1. At this time, because the baffle 3 previously pushed the gypsum slurry to the middle direction of the thick board paper 5, the return stroke of the baffle 3 will not push the gypsum slurry from the thick board paper 5. It can be known to those skilled in the art that if Fig.15 as well as Fig.16As shown, since the ends of the two baffles 3 away from the extrusion molding member 2 are inclined surfaces, the inclined surfaces are inclined downward from the end close to the extrusion molding member 2 to the end away from the extrusion molding member 2, so that after the baffle 3 pushes the gypsum slurry to the middle direction of the thick cardboard 5, the inclined surface on the baffle 3 faces the side of the slurry feeding pipe body 8, so that the inclined surfaces of the two baffles 3 have the effect of gathering the gypsum slurry, and when the two baffles 3 slide to the end of the stroke, the ends of the baffles 3 will always block the edges of the thick cardboard 5, so that the baffle 3 will not push the gypsum slurry from the thick cardboard 5 during the return process, and this is repeated, and the active groove 16 can be driven to rotate by the active disc 15, so that the active disc 15 can drive the T-shaped rod 13, the sliding rod 11 and the baffle 3 to perform a linear reciprocating motion through the active groove 16, so that the baffle 3 pushes the gypsum slurry from the side of the thick cardboard 5 to the middle thereof, preventing the gypsum slurry from flowing out from the side of the thick cardboard 5.

[0046] In another embodiment provided by the present invention, a smoothing mechanism is provided on each of the two straight plates 4, and the smoothing mechanism is used to evenly spread the gypsum slurry on the thick board paper 5. The smoothing mechanism includes a positioning shaft 20, and a through groove 21 is provided on each of the two straight plates 4. A positioning shaft 20 is rotatably installed in each of the two through grooves 21, and a smoothing brush 22 is installed on each of the two positioning shafts 20. A receiving groove 23 is provided on each of the two straight plates 4, and the two receiving grooves 23 are respectively connected to the sliding hole 12 on the same straight plate 4, and an active rack 24 is provided on each of the two sliding rods 11. The bottom ends of the two positioning shafts 20 pass through the inner wall of the top end of the receiving groove 23 and are connected to a driven gear 25, and the two driven gears 25 are respectively meshed with their corresponding active racks 24.

[0047] Specifically, when the active disc 15 drives the T-shaped rod 13 and the sliding rod 11 to perform linear reciprocating motion through the active groove 16, the sliding rod 11 drives the active rack 24 to perform linear reciprocating motion. When the T-shaped rod 13 slides along the trajectory of the annular groove body 17, the active rack 24 and the driven gear 25 are meshed with each other, and no movement occurs between the active rack 24 and the driven gear 25. At this time, the smoothing brush 22 faces one side of the extruded plastic part 2, so that the two smoothing brushes 22 are combined into a "V"-shaped structure (such as Figure 1 and Figure 3As shown in the figure, during the sliding of the T-shaped rod 13 along the trajectory of the arc protrusion 18, the T-shaped rod 13 drives the sliding rod 11 to perform linear reciprocating motion, and the sliding rod 11 drives the active rack 24 to perform linear reciprocating motion. Since the active rack 24 and the driven gear 25 are meshed with each other, the active rack 24 drives the driven gear 25 to reciprocate, and the driven gear 25 drives the positioning shaft 20 to reciprocate, and the positioning shaft 20 drives the smoothing brush 22 to swing back and forth, so that the smoothing brush 22 evenly spreads the gypsum slurry at the position of the extruded molding part 2 of the thick board paper 5, and reduces the accumulation of gypsum slurry at the position of the extruded molding part 2. At the same time, the reciprocatingly swinging smoothing brush 22 can smooth the gypsum slurry on the thick board paper 5, thereby providing the flatness of the gypsum board surface and improving the production quality of the gypsum board.

[0048] In another embodiment provided by the present invention, each of the two straight plates 4 is provided with an arc rod 26, and the top ends of the two arc rods 26 are evenly provided with a plurality of first teeth 27 along the circumferential direction thereof, and the centers of the two arc rods 26 coincide with the centers of the corresponding positioning shafts 20, and each of the two positioning shafts 20 is provided with a square rod 28, and each of the two square rods 28 is rotatably provided with a driven shaft 29, and one end of each of the two driven shafts 29 is provided with the above-mentioned smoothing brush 22, and the other ends of the two driven shafts 29 penetrate the corresponding square rods 28 and are connected with a half-face gear 30, that is, an incomplete gear with 180-degree teeth, and the two half-face gears 30 are respectively meshed with the corresponding first teeth 27, and the top ends of the two square rods 28 are each provided with There is a positioning mechanism, which includes a friction plate 31, a through groove 32 is provided on each of the two square rods 28, a straight rod 33 is slidably installed in each of the two through grooves 32, one end of the two straight rods 33 (that is, the inner end of the straight rod 33 located in the through groove 32) is connected with the friction plate 31, the two friction plates 31 are respectively frictionally limited with their corresponding driven shafts 29, the two straight rods 33 and the inner walls of the through grooves 32 are connected by elastic members 36, the other ends of the two straight rods 33 are respectively provided with a groove 34, and an active push rod 35 is respectively provided on the two straight plates 4, the two active push rods 35 are respectively cooperated with their corresponding grooves 34, and the abutting surfaces of the two active push rods 35 and the grooves 34 are inclined surfaces.

[0049] Specifically, in the process that the active disc 15 drives the T-shaped rod 13 and the sliding rod 11 to perform linear reciprocating motion through the active groove 16, synchronously, the T-shaped rod 13 and the sliding rod 11 drive the driven gear 25 to reciprocate through the active rack 24, and the driven gear 25 drives the positioning shaft 20 and the square rod 28 to swing back and forth. In the process that the square rod 28 swings back and forth, when the square rod 28 slides toward the end away from the extruded plastic part 2, the elastic member 36 (the elastic member 36 is a component that can be retracted and reset, preferably a spring) provides elastic force for the straight rod 33, so that the straight rod 33 presses the friction plate 31 against the surface of the driven shaft 29, so that the friction plate 31 positions the driven shaft 29 under the elastic force of the elastic member 36. As can be known to those skilled in the art, in order to increase the friction between the friction plate 31 and the driven shaft 29, a rubber material can be provided on the friction plate 31 (or the abutment position of the driven shaft 29 and the friction plate 31), thereby increasing the friction between the friction plate 31 and the driven shaft 29. When the other end of the driven shaft 29 drives the half-face gear 30 to rotate to a position where it meshes with the first teeth 27 on the arc-shaped rod 26, due to the mutual meshing between the first teeth 27 and the half-face gear 30, the first teeth 27 are fixedly arranged on the arc-shaped rod 26, so that the half-face gear 30 forcibly drives the driven shaft 29 to rotate (that is, due to the elastic force applied by the elastic member 36 to the straight rod 33, the friction plate 31 is engaged with the straight rod 33). The driven shaft 29 is frictionally positioned, and the driven shaft 29 does not rotate. However, due to the meshing of the first teeth 27 and the half-face gear 30, the friction force applied by the friction plate 31 to the driven shaft 29 cannot block the force generated by the meshing of the first teeth 27 and the half-face gear 30, so that the half-face gear 30 can drive the driven shaft 29 to rotate). Since there are only half of the teeth on the annular outer wall of the half-face gear 30, the first teeth 27 on the arc rod 26 are only 180 degrees meshed with the half-face gear 30. When the teeth on the half-face gear 30 are disengaged from the first teeth 27, the half-face gear 30 is no longer meshed with the first teeth 27. At this time, the half-face gear 30 drives the driven shaft 29 to rotate 180 degrees, and the driven shaft 29 drives the smoothing brush 22 to rotate 1 80 degrees, so that the smoothing brush 22 will not contact the gypsum slurry during the swinging process, so that the smoothing brush 22 will not push the gypsum slurry back to the position of the extruded molding part 2 for accumulation, and the friction plate 31 continues to frictionally position the driven shaft 29, and the half surface of the half-face gear 30 without teeth swings back from the top of the first tooth 27, so that the smoothing brush 22 swings back following the square rod 28 after rotating to 180 degrees, until the active push rod 35 and the groove 34 abut against each other, because the top of the active push rod 35 is an inclined surface, the groove 34 on the straight rod 33 slides along the trajectory of the inclined surface on the active push rod 35, and under the push of the inclined surface on the active push rod 35, the straight rod 33 slides upward under the push of the groove 34,The straight rod 33 drives the friction plate 31 and the driven shaft 29 to disengage from each other, so that the friction plate 31 releases the friction positioning of the driven shaft 29. Under the action of the self-weight of the smoothing brush 22, the smoothing brush 22 drives the driven shaft 29 to rotate 180 degrees, so that the smoothing brush 22 can smooth the gypsum slurry accumulated at the position of the extruded plastic part 2 again, and the teeth on the half-face gear 30 can mesh with the first teeth 27 again. During the next swinging of the smoothing brush 22 and the driven shaft 29, the active push rod 35 and the groove 34 on the straight rod 33 are disengaged from each other. Under the elastic force of the elastic member 36, the elastic member 36 presses the friction plate 31 against the driven shaft 29 through the straight rod 33, so that the friction plate 31 positions the driven shaft 29 under the elastic force of the elastic member 36. This reciprocating process can achieve that when the smoothing brush 22 swings away from the end of the extruded plastic part 2, the smoothing brush 22 can smooth the extruded plastic part 2. The gypsum slurry accumulated at the position of the extruded plastic part 2 is smoothed, and at the same time, the smoothing brush 22 gradually rotates 180 degrees. When the smoothing brush 22 swings toward one end of the extruded plastic part 2 (that is, the smoothing brush 22 swings back), the smoothing brush 22 is in a state of being rotated 180 degrees (that is, the bristles of the smoothing brush 22 are facing upwards) and swings back until the smoothing brush 22 rotates to the end of the stroke, and the grooves 34 on the active push rod 35 and the straight rod 33 are pressed against each other, so that the straight rod 33 and the friction plate 31 release the friction positioning on the driven shaft 29. During the next swing of the smoothing brush 22, after the grooves 34 on the active push rod 35 and the straight rod 33 are disengaged from each other, under the elastic force of the elastic member 36, the elastic member 36 presses the friction plate 31 against the driven shaft 29 through the straight rod 33, thereby realizing the friction positioning of the friction plate 31 on the driven shaft 29, so that the smoothing brush 22 can smooth the gypsum slurry accumulated at the position of the extruded plastic part 2. ,

[0050] In another embodiment provided by the present invention, since the slurry feeding tube body 8 is fixedly arranged on the auxiliary plate 9, when the smoothing brush 22 swings to the position farthest from the extrusion shaping member 2 (that is, the position where the smoothing brush 22 is closest to the slurry feeding tube body 8), there is a problem that the slurry feeding tube body 8 sprays the gypsum slurry on the smoothing brush 22. In order to solve the above problem, it is necessary to synchronously swing the slurry feeding tube body 8 away from the end of the extrusion shaping member 2 as the smoothing brush 22 gradually swings away from the extrusion shaping member 2, so that the gypsum slurry sprayed in the slurry feeding tube body 8 is sprayed vertically (or nearly vertically) on the thick board paper 5, so that the gypsum slurry sprayed in the slurry feeding tube body 8 will not be sprayed on the smoothing brush 22, thereby causing a waste of gypsum slurry. In order to achieve the above purpose, Fig.13 As shown, a power piece 37 is arranged on the auxiliary plate 9, the middle part of the slurry delivery tube body 8 is connected with a rotary seal, the slurry delivery tube body 8 is rotatably arranged on the auxiliary plate 9, and the output end of the power piece 37 is connected to the end of the slurry delivery tube body 8.

[0051] Specifically, when the smoothing brush 22 gradually swings away from the end of the extrusion shaping member 2, the power member 37 (the power member 37 is a device that can reciprocate at the output end, preferably a motor) drives the slurry delivery pipe body 8 to rotate synchronously away from the end of the extrusion shaping member 2. When the smoothing brush 22 swings to the position farthest from the extrusion shaping member 2, the slurry delivery pipe body 8 rotates to a position where the gypsum slurry is vertically (or nearly vertically) sprayed on the thick paper 5. When the smoothing brush 22 is swinging back, the power member 37 drives the slurry delivery pipe body 8 to It rotates synchronously with one end close to the extrusion shaping member 2. When the smoothing brush 22 swings back to the position closest to the extrusion shaping member 2, the power member 37 drives the slurry delivery pipe body 8 to rotate to the position where the gypsum slurry is obliquely sprayed onto the thick cardboard 5 (that is, the slurry delivery pipe body 8 rotates to a position where the angle between the slurry delivery pipe body 8 and the thick cardboard 5 is 45 degrees or close to 45 degrees), so that the slurry delivery pipe body 8 swings synchronously to transport the gypsum slurry to the thick cardboard 5, thereby preventing the problem of gypsum slurry being sprayed on the smoothing brush 22 due to the swing of the smoothing brush 22.

[0052] As a preferred embodiment of another embodiment provided by the present invention, the end of the slurry delivery pipe body 8 is connected to a passive gear 38, and a supporting plate 39 is arranged at the top of the mounting plate 6 away from the end of the driving member 19, and a Z-shaped rod 40 is slidably installed on the supporting plate 39, and one end of the Z-shaped rod 40 is pressed against the outer wall of the active disc 15 away from the side of the driving member 19, and a protrusion 41 is arranged on the outer wall of the active disc 15 away from the side of the driving member 19 and located on the arc protrusion 18. The arc protrusion 18 and the protrusion 41 are located on the same diameter direction of the active disc 15, and the protrusion 41 and the Z-shaped rod 40 are arranged in cooperation with each other, and the supporting plate 39 and the Z-shaped rod 40 are connected by a spring rod 42, and the other end of the Z-shaped rod 40 is evenly provided with a plurality of second teeth 43, and each of the second teeth 43 is meshed with the passive gear 38.

[0053] Specifically, in the process of the driving member 19 driving the active disc 15 to rotate, when the arc convex portion 18 on the active disc 15 and the T-shaped rod 13 abut against each other, the T-shaped rod 13 slides along the trajectory of the arc convex portion 18, and the T-shaped rod 13 drives the sliding rod 11 to slide in the sliding hole 12 toward one end of the U-shaped frame 1, and the sliding rod 11 drives the active rack 24 to slide toward one end of the U-shaped frame 1, and the active rack 24 drives the driven gear 25 to rotate, and the driven gear 25 drives the positioning shaft 20 rotates, the positioning shaft 20 drives the smoothing brush 22 to rotate away from the end of the extrusion molding member 2. At this time, the active disc 15 drives the protrusion 41 and the Z-shaped rod 40 to abut against each other. Under the tight action of the protrusion 41 and the Z-shaped rod 40, the Z-shaped rod 40 gradually slides toward one end of the slurry feeding pipe body 8, and the Z-shaped rod 40 stretches the spring rod 42. Synchronously, the second teeth 43 on the Z-shaped rod 40 and the passive gear 38 are meshed with each other, so that the Z-shaped rod 40 drives the passive gear 38 The driven gear 38 drives the slurry delivery pipe body 8 to rotate, so that the slurry delivery pipe body 8 rotates to a position where the gypsum slurry is vertically (or nearly vertically) sprayed on the thick paper 5. When the T-shaped rod 13 slides along the track of the annular groove body 17, the Z-shaped rod 40 and the protrusion 41 are separated from each other. Under the pulling action of the spring rod 42, the Z-shaped rod 40 slides to the end away from the mounting plate 6, and the second teeth 43 on the Z-shaped rod 40 and the driven gear 38 are meshed with each other, so that the Z-shaped rod 40 drives the passive gear 38 to rotate, and the passive gear 38 drives the slurry delivery pipe body 8 to rotate, so that the passive gear 38 drives the slurry delivery pipe body 8 to rotate to a position where the gypsum slurry is obliquely sprayed onto the thick cardboard 5 (that is, the slurry delivery pipe body 8 rotates to a position where the angle between the slurry delivery pipe body 8 and the thick cardboard 5 is 45 degrees or close to 45 degrees), so that the slurry delivery pipe body 8 can swing synchronously with the swing of the smoothing brush 22, thereby preventing the problem of gypsum slurry being sprayed on the smoothing brush 22 due to the swing of the smoothing brush 22.
