Description

Technical Field

[0001] This invention belongs to the field of board flipping technology, specifically a cement board processing board flipping machine. Background Technology

[0002] Cement boards are commonly used in the construction industry as raw materials for precast cement walls. During the processing of precast cement walls, both sides of the cement board need to be processed. However, due to the weight of the cement board, manual turning is inconvenient. Therefore, a board turning machine is generally used. The turning machine includes two rotating support platforms with side support claws. The cement board is placed on one of the support platforms. When turning is needed, both support platforms rotate to a vertical position, at which point the cement board is positioned between the two support platforms and pressed against the side support claws. Then, the other support platform rotates, taking the cement board with it to a horizontal position. The cement board is then turned to a horizontal position along with the other support platform, completing the turning process. However, the following drawbacks exist:

[0003] When rotated to a vertical position, there may be a certain gap between the cement slab and the two support platforms, which may cause the cement slab to impact and collide with the support platforms during the flipping process, thereby damaging the cement slab. Summary of the Invention

A support plate is slidably installed inside the plate groove. The support plate and the push plate are on the same horizontal plane. After the support plate moves outward, the top wall of the support plate can support the bottom wall of the rotating block. A magnetic block is fixedly installed on the support plate. An electromagnet is fixedly installed on the inner wall of the end of the plate groove on the side away from the receiving groove. The electromagnets are connected in series.

[0012] Preferably, guide blocks are symmetrically installed on both sides of the support plate, the guide blocks are slidably installed inside the guide groove, the guide groove is symmetrically opened on the inner walls of both sides of the plate groove, a second spring is fixedly installed on the side of the guide block near the receiving groove, one end of the second spring is fixedly connected to the inner wall of the end of the guide groove, and an auxiliary fixing member is provided at the top of the plate groove.

[0016] Preferably, a relative movement drive mechanism is installed between the two movable seats and the base, the relative movement drive mechanism being used to drive the two movable seats to move relative to each other.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1) During operation, the support components consist of a support arm and a push arm. The support arm can support the platform to rotate to a vertical position to support the cement board. When the support arm rotates, it can separate from the cement board, allowing the cement board to fall completely onto the support arm on another support platform. The push arm rotates to push the cement board closer to the other support platform, ensuring that there is no gap between the cement board and the support platform. This facilitates the flipping of the cement board and prevents impact collisions between the cement board and the support platform.

[0019] 2) During operation, when the electromagnet generates a repulsive force on the magnetic block, the support plate moves outward to the side of the support arm away from the cement board, limiting the support arm so that when the support platform rotates to the vertical position, it can support the cement board. At the same time, the outward movement of the support plate drives the limit plate to rotate and press the cement board, improving the rotational stability of the cement board.

[0020] 3) During operation, after the support arm is limited by the set support plate, the surface of the push arm is in close contact with the end face of the suction cup. At the same time, the support plate moves outward, driving the piston rod to move in the opposite direction, so that the suction cup and the push arm are fixed by negative pressure adsorption, which further improves the support stability of the support arm for the cement board.

[0021] 4) During operation, when the electromagnet generates a repulsive force on the magnetic block, the support plate moves back and enters the plate groove. After the limit plate rotates, the piston rod extends to the outside, pushing the support arm and the push arm to rotate. This causes the cement plate to separate from the support arm that was previously in contact with it. The push arm then pushes the cement plate to move towards another support platform and make contact, improving the stability of the transfer and avoiding impact. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] Depend on Figures 1 to 7The present invention relates to a cement board processing board turning machine, comprising a base 1, and two board turning components 2 symmetrically arranged above the base 1;

[0034] The panel flipping assembly 2 includes a movable seat 201 symmetrically arranged above the base 1. Side plates 202 are symmetrically installed on the top of the movable seat 201. A support platform 203 for horizontal support of the cement board is rotatably installed between the two side plates 202. Longitudinal support members 205 are equidistantly arranged on the support platform 203. A push hydraulic cylinder 204 is installed on the movable seat 201. The output end of the push hydraulic cylinder 204 is hinged to the support platform 203. The push hydraulic cylinder 204 is used to push the support platform 203 to rotate.

[0035] The longitudinal support member 205 includes accommodating grooves 2051 equidistantly spaced on the support platform 203. A support arm 2052 is provided inside the accommodating groove 2051, perpendicular to the support platform 203. A connecting shaft 2053 is mounted on one end of the support arm 2052 inside the accommodating groove 2051, rotatably connected to the support platform 203. A pushing arm 2054 is fixedly mounted on one end of the support arm 2052, concealed within the accommodating groove 2051 and perpendicular to the support arm 2052. An end limiting member 206 is provided at the other end of the support arm 2052. The support platform 203 contains a useful... The bottom support 207 limits the support arm 2052 and also drives the end limiter 206 to work. The receiving grooves 2051 on the two support platforms 203 are staggered. The support arm 2052 and the push arm 2054 form a support. The support arm 2052 can support the platform 203 to rotate to a vertical position to support the cement board. When the support arm 2052 rotates, it can separate from the cement board, so that the cement board falls completely on the support arm 2052 on the other support platform 203. The push arm 2054 rotates to push the cement board closer to the other support platform 203, which facilitates the flipping of the cement board.

[0036] The end limiting member 206 includes a rotating groove 2061 formed at the end of the support arm 2052 away from the push arm 2054. A rotating block 2062 is rotatably mounted inside the rotating groove 2061. A limiting plate 2063 is installed on the side of the rotating block 2062 away from the push arm 2054. A rotating shaft is coaxially mounted on the rotating block 2062 and rotatably connected to the support arm 2052. Gears 2064 are symmetrically and coaxially mounted at both ends of the rotating shaft. A rack 2069 is meshed below the gears 2064. A sliding block 2066 is provided below the support arm 2052. The sliding block 2066 is fixedly connected to two racks 2069. The sliding block 2066 is slidably connected to the sliding groove 2065. The sliding groove 2065 is opened at the bottom end of the support arm 2052. A first spring 2068 is fixedly installed on the side of the sliding block 2066 away from the push arm 2054. One end of the first spring 2068 is fixedly connected to the inner wall of the end of the sliding groove 2065. A push plate 2067 is fixedly installed on the side of the sliding block 2066 near the support platform 203.

[0037] The bottom support 207 includes a plate groove 2071 formed at the bottom end of the receiving groove 2051 on the side away from the support arm 2052. A support plate 2072 is slidably installed inside the plate groove 2071. The support plate 2072 and the push plate 2067 are on the same horizontal plane. After the support plate 2072 moves outward, the top wall of the support plate 2072 can support the bottom wall of the rotating block 2062. A magnet 2076 is fixedly installed on the support plate 2072. An electromagnet 2077 is fixedly installed on the inner wall of the end of the plate groove 2071 away from the receiving groove 2051. The electromagnets 2077 are connected in series. Guide blocks 2074 are symmetrically installed on both sides of the support plate 2072. The guide blocks 2074 are slidably installed in the guide groove 2073. The guide grooves 2073 are symmetrically opened on the inner walls of both sides of the plate groove 2071. A second spring 2075 is fixedly installed on the side of the guide block 2074 near the receiving groove 2051. One end of the second spring 2075 is fixedly connected to the inner wall of the end of the guide groove 2073. An auxiliary fixing member 208 is provided at the top of the plate groove 2071. When the electromagnet 2077 generates a repulsive force on the magnetic block 2076, the support plate 2072 moves outward to the side of the support arm 2052 away from the cement board, limiting the support arm 2052 so that the cement board can be supported when the support platform 203 rotates to the vertical state. At the same time, the outward movement of the support plate 2072 drives the limiting plate 2063 to rotate and press the cement board, improving the rotational stability of the cement board.

[0038] The auxiliary fixing component 208 includes a top groove 2081 formed at the top of the plate groove 2071. A transverse groove 2082 is formed at the top of the top groove 2081 near the receiving groove 2051, extending into the receiving groove 2051. A suction cup 2083 is fixedly installed on the inner wall of the receiving groove 2051 near the top groove 2081, and the suction cup 2083 is connected to the transverse groove 2082. The end face of the suction cup 2083 contacts the side wall of the pushing arm 2054 away from the support arm 2052. A piston rod 2084 is movably installed inside the transverse groove 2082. The outer wall of the piston rod 2084 is in close contact with the inner wall of the transverse groove 2082, and one end of the piston rod 2084 extends into the top groove 2081. After the support plate 2072 limits the support arm 2052, the surface of the pushing arm 2054 is in close contact with the end face of the suction cup 2083, and at the same time, the support plate 2072 moves outward. The piston rod 2084 is driven to move in the opposite direction, causing the suction cup 2083 and the push arm 2054 to be fixed by negative pressure adsorption, further improving the support stability of the support arm 2052 for the cement board. An end block 2085 is fixedly installed at the end of the piston rod 2084 away from the suction cup 2083. The end block 2085 is slidably connected to the top groove 2081. A connecting drive component 209 is provided between the end block 2085 and the support plate 2072. When the electromagnet 2077 generates a repulsive force on the magnetic block 2076, the support plate 2072 moves back and enters the plate groove 2071. After the limit plate 2063 rotates, the piston rod 2084 extends to the outside, pushing the support arm 2052 and the push arm 2054 to rotate. After the cement board separates from the support arm 2052 that was originally in contact, the push arm 2054 pushes the cement board to move towards another support platform 203 and make contact, improving the transfer stability and avoiding impact.

[0039] The connecting drive component 209 includes a shaft 2091 disposed between the end block 2085 and the support plate 2072. The shaft 2091 is rotatably connected to the side wall of the top groove 2081. Guide cylinders 2092 are symmetrically fixedly installed on the upper and lower sides of the shaft 2091. Guide rods 2093 are slidably installed inside the guide cylinders 2092. Connecting hinges 2094 are installed at the ends of the two guide rods 2093 away from the shaft 2091. The two connecting hinges 2094 are bolted to the end block 2085 and the support plate 2072 respectively.

[0040] A relative movement drive mechanism 3 is installed between the two movable seats 201 and the base 1. The relative movement drive mechanism 3 is used to drive the two movable seats 201 to move relative to each other.

[0041] Working principle: During operation, both support platforms 203 are generally in a horizontal state. The hydraulic cylinder 204 is pushed to support the support platforms 203. The cement board to be processed is placed horizontally on one side of the support platform 203, and then one side surface of the cement board is processed.

[0042] Then the cement slab is flipped over. At this time, the electromagnet 2077 is energized, which generates a repulsive force on the magnetic block 2076, pushing the support plate 2072 to move outward until the support plate 2072 moves to the side of the support arm 2052 away from the cement slab and is in close contact with it, thus limiting the position of the support arm 2052. At the same time, the cement slab contacts the other side of the support arm 2052. During the outward movement of the support plate 2072, the push plate 2067 is pushed to move along the sliding groove 2065, which drives the rack 2069 to move. The rack 2069 meshes with the gear 2064, thereby driving the rotating block 2062 to rotate, so that the limiting plate 2063 moves toward the cement slab until the end of the limiting plate 2063 is pressed against the surface of the cement slab, thus limiting the cement slab and preventing it from tipping over when the cement slab is rotated to a vertical position.

[0043] When the support plate 2072 moves outward, the guide rod 2093 pulls the shaft 2091 to rotate, which in turn drives the piston rod 2084 to move along the transverse groove 2082 toward the inside of the top groove 2081. When the support plate 2072 supports one side of the support arm 2052, the support arm 2052 is positioned so that one side of the push arm 2054 is in close contact with the end face of the suction cup 2083. Then, a negative pressure suction force is generated between the suction cup 2083 and the push arm 2054, which increases the support force of the support arm 2052 when the cement board is rotated to a vertical position, thereby improving the support stability.

[0044] Then, the relative movement drive mechanism 3 is activated, driving the two moving seats 201 to move closer to each other. Then, the hydraulic cylinders 204 on the two moving seats 201 are pushed to extend the output end of the hydraulic cylinders 204 outward, pushing the support platform 203 to gradually rotate to a vertical state. Since the receiving grooves 2051 on the two support platforms 203 are staggered, the rotation of the support platform 203 will not be hindered.

[0045] After rotating to the vertical position, the cement slab is in a vertical position and is located between the two support platforms 203. At this time, the electromagnet 2077 on the other support platform 203 is controlled to pass a positive current, causing the support plate 2072 to move outward to support the support arm 2052 and drive the limiting plate 2063 to rotate until the end of the limiting plate 2063 contacts the bottom wall of the cement slab. At this time, the support plate 2072 is blocked and cannot continue to move outward, so the limiting plate 2063 cannot rotate upward smoothly.

[0046] Then, control the electromagnet 2077 on the support platform 203 on the side where the cement board was originally placed to pass a reverse current, so that the electromagnet 2077 attracts the magnetic block 2076, causing the support plate 2072 to move back towards the plate groove 2071 and then continue to move towards the inside of the plate groove 2071, thereby driving the piston rod 2084 to move outward through the shaft 2091.

[0047] During the retraction of the support plate 2072, the sliding block 2066 retracts under the elastic force of the first spring 2068, causing the rack 2069 to retract and drive the rotating block 2062 to rotate, so that the limiting plate 2063 no longer limits the cement board.

[0048] The piston rod 2084 moves outward and exerts pressure on the push arm 2054, which pushes the support arm 2052 to rotate downward. The push arm 2054 pushes the cement board to move towards the support platform 203 on the other side and make contact with it, so as to avoid the cement board from collided with the support platform 203 after it flips over.

[0049] Then, the hydraulic cylinder 204 is pushed to pull the support platform 203 to rotate. At this time, the cement board is transferred to another support platform 203 and flipped. Then, the other side of the cement board is processed. During the rotation, since the support plate 2072 is no longer obstructed from moving outward, the support plate 2072 continues to move outward, causing the limiting plate 2063 to rotate and limit the cement board.
