Description

Technical Field

[0001] This invention relates to the field of pusher plate technology, specifically a novel gypsum board pusher plate device. Background Technology

[0002] In the production and processing of gypsum board, the pusher device is an indispensable auxiliary equipment. It is mainly used to push the cut and shaped gypsum board from the production station to the next processing stage or storage area. Its operational stability and pushing efficiency directly affect the production progress and product quality of gypsum board. It is widely used in gypsum board processing production lines in the field of building materials production.

[0003] Existing gypsum board pushing devices have certain shortcomings in practical use. Due to the lack of an effective friction-reducing structure, the contact area between the gypsum board and the device is prone to significant friction when pushing the gypsum board. Since gypsum board is brittle, this friction can cause scratches and damage to the surface, affecting the integrity of the product. At the same time, most existing devices cannot stably position the gypsum board, often requiring manual assistance to fix it during the pushing process. This not only increases the labor intensity but also makes it easy for the gypsum board to shift or fall, thereby reducing pushing efficiency and increasing gypsum board waste. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a novel gypsum board pushing device to solve the problems mentioned in the background art, such as scratches and damage on the surface of gypsum boards affecting product integrity; and the tendency for gypsum boards to shift or fall off, thereby reducing pushing efficiency and increasing gypsum board losses.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a novel gypsum board pusher device, comprising: A support frame, wherein a first cylinder is mounted on the upper surface of the support frame, and a movable frame is mounted on the output end of the first cylinder; The second cylinder is located on the upper surface of the movable frame. A connecting plate is installed at the output end of the second cylinder. A fixing plate is installed on the surface of the connecting plate. A first pulley is installed at the bottom of the fixing plate. A second pulley is installed on the end face of the connecting plate. An installation frame is installed on the lower part of the surface of the fixing plate. A third pulley is installed in the inner cavity of the installation frame. A mounting plate is disposed on the surface of the movable frame. A motor is mounted on the upper surface of the mounting plate. A lead screw is coaxially mounted on the rotor of the motor. An adjusting rod is screwed onto the surface of the lead screw. A mounting box is mounted on the output end of the adjusting rod. A suction cup is mounted on the bottom of the mounting box. A vacuum pump is mounted on the upper surface of the mounting plate. The vacuum pump is connected to the interior of the mounting box through a pipe.

[0006] Preferably, an mounting bracket is installed on the upper surface of the movable frame, and the second cylinder is mounted on the inner wall of the mounting bracket via a rotating shaft. With the mounting bracket and the rotating shaft, the second cylinder can rotate at a certain angle around the rotating shaft. Thus, when the second cylinder pushes the connecting plate and other components, it can better adapt to the pushing requirements at different angles, improve the flexibility and applicability of the device, and avoid the situation where the gypsum board cannot be accurately pushed due to a fixed angle.

[0007] Preferably, a connector is installed at the output end of the second cylinder, and a connecting ring is installed on the upper surface of the connecting plate. The connector is connected to the connecting ring via a rotating shaft, enabling relative rotation between the second cylinder and the connecting plate. When the second cylinder pushes the connecting plate to move, if the connecting plate is subjected to forces in other directions or its movement trajectory needs to be finely adjusted, the rotation of the connector and the connecting ring via the rotating shaft can buffer such force changes, ensuring the stability of the connection and the smoothness of the movement, and reducing component damage and inflexible movement caused by rigid connections.

[0008] Preferably, a slider is mounted on the surface of the fixed plate, and a slide rail is mounted on the surface of the movable frame. The cooperation between the slider and the slide rail provides precise guidance for the movement of the fixed plate on the movable frame. During the operation of the device, when the fixed plate is moved by other components, the slider slides along the slide rail, ensuring that the fixed plate moves along a predetermined trajectory, avoiding deviation or shaking, thereby improving the stability and accuracy of the entire device operation and ensuring the smooth progress of the gypsum board pushing process.

[0009] Preferably, a guide block is installed at the bottom of the movable frame, and a guide rail is installed on the upper surface of the support frame. The combination of the guide block and the guide rail provides guidance and limiting functions for the movement of the movable frame on the support frame. When the first cylinder pushes the movable frame to move, the guide block slides within the guide rail, ensuring that the movable frame can only move along the direction of the guide rail, without lateral deviation or vertical swaying. This guarantees the straightness and stability of the movable frame's movement, thereby ensuring that the entire pusher device can accurately push the plasterboard to the designated position.

[0010] Preferably, a reinforcing block is installed on the upper surface of the support frame, and the first cylinder is mounted on the surface of the reinforcing block. The reinforcing block enhances the connection strength between the first cylinder and the support frame. Since the first cylinder needs to withstand significant thrust and tension during operation, direct mounting on the support frame could lead to loosening or damage at the connection points. The reinforcing block disperses the force exerted by the first cylinder on the support frame, improving connection stability, extending the service life of the device, and ensuring the first cylinder operates stably and reliably, providing continuous power for the movement of the mobile frame.

[0011] Preferably, a support plate is installed at the bottom of the support frame. This support plate is inclined, which increases the contact area and stability between the support frame and the ground. Compared to a traditional horizontal support plate, the inclined support plate better distributes the weight borne by the support frame and the forces generated during device operation, reducing the pressure of the support frame on the ground and preventing tilting or swaying due to uneven stress. Simultaneously, the inclined support plate can adapt to uneven ground to a certain extent, improving the adaptability and stability of the device in different working environments.

[0012] Preferably, a limit rod is installed on the upper surface of the mounting box, penetrating the surface of the mounting plate. The limit rod restricts the movement range of the mounting box. When the motor drives the lead screw to rotate, thereby causing the adjusting rod to move the mounting box up and down, the limit rod moves along with the mounting box. When the mounting box moves to the set upper or lower limit position, the limit rod will contact the corresponding part of the mounting plate, preventing the mounting box from moving further. This prevents the mounting box from colliding with or being damaged by other components due to excessive movement, ensuring the safe operation of the device.

[0013] Preferably, flanges are installed on both the bottom of the mounting box and the upper surface of the suction cup, and a sealing ring is installed between the flanges. The flanges facilitate the installation and disassembly of the suction cup and the mounting box. When the suction cup needs to be replaced or maintained, it can be easily done by operating the connecting parts on the flanges. The installation of the sealing ring ensures a tight seal between the mounting box and the suction cup, preventing air from entering the mounting box through the gaps when the vacuum pump is drawing a vacuum, which would affect the suction cup's adsorption effect on the gypsum board. This ensures that the suction cup can stably and reliably adsorb the gypsum board, guaranteeing a smooth pushing process.

[0014] Preferably, bolts are installed at the bottom of the flange, and these bolts pass through the lower flange and screw onto the surface of the upper flange. This bolt connection provides a secure fixation between the flanges. By passing bolts through the lower flange and screwing them onto the surface of the upper flange, the two flanges can be tightly connected, ensuring that the suction cup and mounting box will not loosen or separate during device operation. This connection method also facilitates disassembly and installation; when maintenance or replacement of the suction cup or mounting box is required, simply unscrewing the bolts allows for separation, improving the maintenance efficiency and convenience of the device.

[0015] Compared with the prior art, the present invention provides a novel gypsum board pusher device, which has the following beneficial effects: This novel gypsum board pushing device uses a first cylinder to move a movable frame, allowing for flexible adjustment of the pushing board's position. A second cylinder moves a connecting plate up and down. A fixing plate mounted on the surface of the connecting plate provides auxiliary positioning for the gypsum board. A first pulley at the bottom of the fixing plate, a second pulley on the end face of the connecting plate, and a third pulley in the inner cavity of the mounting frame at the bottom of the fixing plate reduce friction between the gypsum board and other components during the pushing process, preventing scratches or damage to the gypsum board surface and ensuring its integrity. A motor and lead screw move an adjusting rod screwed onto its surface, thereby adjusting the position of the mounting box. The suction cup at the bottom of the mounting box, under the negative pressure provided by a vacuum pump through a pipeline, stably adsorbs the gypsum board, preventing it from shifting or falling during the pushing process and improving stability. Furthermore, it eliminates the need for manual fixing and pushing of the gypsum board, effectively improving the efficiency and quality of gypsum board pushing and reducing losses during the process.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides a technical solution: a novel gypsum board pusher device. Please refer to [link / reference]. Figure 1 It includes a support frame 1, a first cylinder 2 is mounted on the upper surface of the support frame 1, and a movable frame 3 is mounted on the output end of the first cylinder 2; Please see Figure 3 and Figure 4 The second cylinder 4 is located on the upper surface of the movable frame 3. A connecting plate 5 is installed at the output end of the second cylinder 4. A fixing plate 6 is installed on the surface of the connecting plate 5. A first pulley 61 is installed at the bottom of the fixing plate 6. A second pulley 7 is installed on the end face of the connecting plate 5. An installation frame 8 is installed at the lower part of the surface of the fixing plate 6. A third pulley 9 is installed in the inner cavity of the installation frame 8. Mounting plate 10 is disposed on the surface of movable frame 3. Motor 11 is mounted on the upper surface of mounting plate 10. Please refer to [link / reference]. Figure 5 The rotor of motor 11 is coaxially mounted with lead screw 12. Adjusting rod 13 is screwed onto the surface of lead screw 12. Mounting box 14 is mounted on the output end of adjusting rod 13. Suction cup 15 is mounted on the bottom of mounting box 14. Vacuum pump 16 is mounted on the upper surface of mounting plate 10. Vacuum pump 16 is connected to the inside of mounting box 14 through a pipe.

[0020] The support frame 1 provides stable support for the entire device. The first cylinder 2 installed on its upper surface can drive the movable frame 3 to move, realizing flexible adjustment of the pusher position to meet the position requirements of gypsum board pushing in different scenarios. The second cylinder 4 installed on the upper surface of the movable frame 3 can drive the connecting plate 5 to move up and down. The fixing plate 6 installed on the surface of the connecting plate 5 can play an auxiliary limiting role for the gypsum board. The first pulley 61 at the bottom of the fixing plate 6, the second pulley 7 on the end face of the connecting plate 5, and the third pulley 9 in the inner cavity of the mounting frame 8 at the lower part of the surface of the fixing plate 6 are used to reduce the friction between the connecting plate 5 and the movable frame 3 during the lifting and lowering process. This can reduce the friction between the gypsum board and other parts of the device during the pushing process, avoid scratches or damage to the surface of the gypsum board due to friction, and ensure the integrity of the gypsum board. The mounting plate 10 on the surface of the movable frame 3 provides a mounting carrier for the motor 11 and the vacuum pump 16. The lead screw 12, which is coaxially mounted on the rotor of the motor 11, can drive the adjusting rod 13 screwed onto its surface to move, thereby driving the mounting box 14 to adjust its position. Under the action of the negative pressure provided by the vacuum pump 16 through the pipeline, the suction cup 15 at the bottom of the mounting box 14 can stably adsorb the gypsum board, avoiding the gypsum board from shifting or falling during the pushing process, thus improving the stability of the pushing process. At the same time, there is no need for manual fixing and pushing of the gypsum board, which effectively reduces the intensity of manual labor. Through the coordinated cooperation of various structures, the gypsum board pushing process is smoother and more efficient. The overall structural design is compact and reasonable, and the components are closely matched, which can effectively improve the efficiency and quality of gypsum board pushing and reduce the loss of gypsum board during the pushing process.

[0021] Please see Figure 7 The upper surface of the movable frame 3 is equipped with a mounting frame 17. The second cylinder 4 is mounted on the inner wall of the mounting frame 17 via a rotating shaft. With the mounting frame 17 and the rotating shaft, the second cylinder 4 can rotate at a certain angle around the rotating shaft. Thus, when the second cylinder 4 pushes the connecting plate 5 and other components, it can better adapt to the needs of pushing the plate at different angles, improve the flexibility and applicability of the device, and avoid the situation of jamming or inaccurate pushing of the gypsum board during the pushing process due to a fixed angle.

[0022] The output end of the second cylinder 4 is equipped with a connector 41, and the upper surface of the connecting plate 5 is equipped with a connecting ring 51. The connector 41 is connected to the connecting ring 51 through a rotating shaft, so that the second cylinder 4 and the connecting plate 5 can rotate relative to each other. When the second cylinder 4 pushes the connecting plate 5 to move, when the connecting plate 5 is subjected to forces in other directions or the movement trajectory needs to be finely adjusted, the connector 41 and the connecting ring 51 can buffer such force changes through the rotation of the rotating shaft, ensuring the stability of the connection and the smoothness of the movement, and reducing component damage and inflexible movement caused by rigid connection.

[0023] Please see Figure 3 and Figure 6A slider 18 is mounted on the surface of the fixed plate 6, and a slide rail 19 is mounted on the surface of the movable frame 3. The cooperation between the slider 18 and the slide rail 19 provides precise guidance for the movement of the fixed plate 6 on the movable frame 3. During the operation of the device, when the fixed plate 6 is moved by other components, the slider 18 slides along the slide rail 19, ensuring that the fixed plate 6 moves along the predetermined trajectory, avoiding deviation or shaking, thereby improving the stability and accuracy of the entire device operation and ensuring the smooth progress of the gypsum board pushing process.

[0024] Please see Figure 3 and Figure 2 A guide block 20 is installed at the bottom of the movable frame 3, and a guide rail 21 is installed on the upper surface of the support frame 1. The combination of the guide block 20 and the guide rail 21 provides guidance and limiting functions for the movement of the movable frame 3 on the support frame 1. When the first cylinder 2 pushes the movable frame 3 to move, the guide block 20 slides in the guide rail 21, so that the movable frame 3 can only move along the direction of the guide rail 21, without any left or right deviation or up or down swaying, ensuring the straightness and stability of the movement of the movable frame 3, and thus ensuring that the entire pusher device can accurately push the plasterboard to the designated position.

[0025] Please see Figure 1 A reinforcing block 22 is installed on the upper surface of the support frame 1, and the first cylinder 2 is mounted on the surface of the reinforcing block 22. The reinforcing block 22 enhances the connection strength between the first cylinder 2 and the support frame 1. Since the first cylinder 2 needs to withstand large thrust and tension during operation, if it is directly installed on the support frame 1, it may cause the connection to loosen or be damaged. The reinforcing block 22 can disperse the force of the first cylinder 2 on the support frame 1, improve the stability of the connection, extend the service life of the device, and ensure that the first cylinder 2 can work stably and reliably, providing continuous power for the movement of the moving frame 3.

[0026] A support plate 23 is installed at the bottom of the support frame 1. The support plate 23 is designed to be inclined, which increases the contact area and stability between the support frame 1 and the ground. Compared with the traditional horizontal support plate 23, the inclined support plate 23 can better distribute the weight borne by the support frame 1 and the forces generated during the operation of the device, reducing the pressure of the support frame 1 on the ground and preventing the support frame 1 from tilting or swaying due to uneven force. At the same time, the inclined support plate 23 can also adapt to uneven ground to a certain extent, improving the adaptability and stability of the device in different working environments.

[0027] Please see Figure 5A limit rod 24 is installed on the upper surface of the mounting box 14, penetrating the surface of the mounting plate 10. The function of the limit rod 24 is to restrict the movement range of the mounting box 14. When the motor 11 drives the lead screw 12 to rotate, thereby causing the adjusting rod 13 to move the mounting box 14 up and down, the limit rod 24 moves along with the mounting box 14. When the mounting box 14 moves to the set upper or lower limit position, the limit rod 24 will contact the corresponding part of the mounting plate 10, preventing the mounting box 14 from continuing to move, thereby preventing the mounting box 14 from colliding or being damaged with other components due to excessive movement, and ensuring the safe operation of the device.

[0028] Please see Figure 4 Flanges 25 are installed on the bottom of the mounting box 14 and the upper surface of the suction cup 15, with sealing rings installed between the flanges 25. The flanges 25 facilitate the installation and disassembly of the suction cup 15 and the mounting box 14. When it is necessary to replace or maintain the suction cup 15, this can be easily accomplished by operating the connecting parts on the flanges 25. The installation of the sealing ring ensures a tight seal between the mounting box 14 and the suction cup 15, preventing air from entering the mounting box 14 through the gap when the vacuum pump 16 is drawing a vacuum, thus affecting the suction cup 15's adsorption effect on the gypsum board. This ensures that the suction cup 15 can stably and reliably adsorb the gypsum board, guaranteeing a smooth pushing process.

[0029] Bolts 26 are installed at the bottom of flange 25. Bolts 26 pass through the lower flange 25 and are screwed onto the surface of the upper flange 25. The connection method of bolts 26 provides a firm fixation between the flanges 25. By passing bolts 26 through the lower flange 25 and screwing them onto the surface of the upper flange 25, the two flanges 25 can be tightly connected together, ensuring that the suction cup 15 and the mounting box 14 will not loosen or separate during the operation of the device. At the same time, this connection method also facilitates disassembly and installation. When it is necessary to repair or replace the suction cup 15 or the mounting box 14, it is only necessary to unscrew the bolts 26 to separate them, which improves the maintenance efficiency and convenience of the device.

[0030] In this design: the support frame 1 is stably placed on the ground with the help of a support plate 23 with an inclined bottom design. A reinforcing block 22 on top strengthens the connection of the first cylinder 2. The first cylinder 2 pushes the movable frame 3, and the guide block 20 at the bottom of the movable frame 3 moves along the guide rail 21 on the support frame 1, ensuring stable linear movement. A mounting bracket 17 on the movable frame 3 mounts a second cylinder 4 via a rotating shaft. The connector 41 at the output end of the second cylinder 4 is connected to the connecting ring 51 on the upper surface of the connecting plate 5 via a rotating shaft, which can drive the connecting plate 5 to move up and down. The slider 18 of the fixed plate 6 on the connecting plate 5 slides along the slide rail 19 on the surface of the movable frame 3. Simultaneously, the first cylinder 20 at the bottom of the fixed plate 6... The first pulley 61, the second pulley 7 on the end face of the connecting plate 5, and the third pulley 9 in the inner cavity of the mounting frame 8 on the lower part of the surface of the fixed plate 6 reduce friction; the motor 11 on the mounting plate 10 on the surface of the moving frame 3 drives the lead screw 12 to rotate, so that the screw-connected adjusting rod 13 drives the mounting box 14 to move. The limiting rod 24 on the upper surface of the mounting box 14 passes through the mounting plate 10 to limit its movement range. The bottom of the mounting box 14 is connected to the upper surface of the suction cup 15 through the flange 25 and the bolt 26, and there is a sealing ring between the flanges 25 to ensure sealing. The vacuum pump 16 provides negative pressure to the inside of the mounting box 14 through the pipeline, so that the suction cup 15 adsorbs the gypsum board and realizes the stable pushing of the gypsum board.
