Abstract
Description
Technical Field
[0001] The present application relates to the technical field of building material processing equipment, and in particular to a stable sheet-closing device for a panel turning machine. Background Art
[0002] During the processing of gypsum board, due to incomplete drying on one side, it is often necessary to turn the gypsum board 180° after drying one side and then dry the other side. At this time, a flipping machine is needed to assist in turning the gypsum board. In addition, after processing, some gypsum boards have one side that is smooth, or have patterns or other structures that need to be protected according to design requirements. Therefore, during the packaging process, the smooth side needs to be in contact with the smooth side, and the untreated back side needs to be in contact with the back side to prevent the untreated back side from scratching the treated front side. However, during the transmission process, the treated front side is on top and the back side is on the bottom in contact with the transmission belt. Therefore, before packaging, the front sides of the two adjacent gypsum boards need to be closed and laid down. Then the stacking robot stacks the two closed gypsum boards and packages them. The aforementioned process of closing the front sides is called sheeting.
[0003] In the prior art, during the flipping process of the panel turning machine, when the gypsum board is turned to a position that is almost upright, another rotating arm will move closer to catch the gypsum board. However, when catching the board, on the one hand, the gypsum board will slide relative to the surface of the rotating arm, and on the other hand, there is a certain angle between the receiving surface of the rotating arm that catches the board and the gypsum board, which makes the gypsum board unstable. In addition, during the closing process, the two gypsum boards are respectively on the surfaces of the two rotating arms. As the two rotating arms rotate relative to each other, the surfaces of the two gypsum boards approach each other, but because the rotating gypsum boards slide and become unstable, the two gypsum boards are also unstable during the closing process. In addition, if the torque borne by the bearings during the flipping process may cause the machine itself to vibrate, this vibration will also cause instability of the mechanism. This instability can easily scratch the gypsum board, thereby affecting the quality of the gypsum board. Utility Model Content

[0023] Gypsum board is a common building material. Its production process involves flipping the board to evenly dry the gypsum board, and also involves a sheet-joining process to position the smooth sides of the gypsum board opposite each other to prevent direct contact between the back and the smooth side, which could damage the smooth side during packaging and transportation. In the prior art, during the flipping process of the panel turning machine, when the gypsum board is turned to a position that is almost upright, another rotating arm will move closer to catch the gypsum board, but when catching the board, on the one hand, the gypsum board will slide relative to the surface of the rotating arm, and on the other hand, there is a certain angle between the receiving surface of the rotating arm that catches the board and the gypsum board, which makes the gypsum board unstable; in addition, during the closing process, the two gypsum boards are respectively on the surfaces of the two rotating arms. As the two rotating arms rotate relative to each other, the surfaces of the two gypsum boards approach each other, but because the rotating gypsum boards slide and become unstable, the two gypsum boards are also unstable during the closing process; in addition, during the flipping process, if the torque borne by the bearings may cause the machine itself to vibrate, this vibration will also cause instability of the mechanism, which can easily scratch the gypsum board, thereby affecting the quality of the gypsum board. Therefore, a stable closing device for a panel turning machine is provided in this embodiment to solve the aforementioned technical problems.
[0024] See Figure 1 and Figure 2 , the utility model will be described in detail below.
[0025] The utility model provides a stable sheet closing device for a flipping machine, such as Figure 1 As shown, it includes a bracket 1, multiple groups of flip assemblies, and the multiple groups of flip assemblies include a first flip mechanism 2 and a second flip mechanism 3 that are relatively arranged. The first flip mechanism 2 includes a gear shaft 6 arranged at the bottom end of the flip plate 9, and the second flip mechanism 3 includes a buffer block 8 with a preset curvature arranged at the bottom end of the flip plate 9; wherein the first flip mechanism 2 and the second flip mechanism 3 also include: a first rotating shaft, a coupling, a first connecting rod 4, a second rotating shaft, a second connecting rod 5, and a mounting seat. The first rotating shaft is connected to the bracket 1 and one end is connected to the driving device The coupling is connected to the first rotating shaft, one end of the first connecting rod 4 is connected to the first rotating shaft through the coupling, the other end of the first connecting rod 4 is hinged to the second connecting rod 5, and the second connecting rod 5 is connected to the flap 9 through the mounting seat; the flap 9 of the first flap mechanism 2 and the flap 9 of the second flap mechanism 3 are arranged opposite to each other; the gear shaft 6 is connected to the driving gear 7 arranged on the bracket 1 through a chain, and the driving gear 7 is connected to the gear drive. The flap mechanism also includes a slide rail, which is arranged on the bracket 1, and the bottom surface of the flap is slidably connected to the slide rail.
[0026] As described above, in the present invention, the flip assembly is composed of the first flip mechanism 2 and the second flip mechanism 3. The multi-link flip mechanism has a simple structure and high flip efficiency. The main thing is that when the first flip mechanism 2 and the second flip mechanism 3 perform the flipping action or the closing action, the sliding gypsum board and the arc-shaped buffer block 8 in the second flip mechanism 3 are abutted to prevent the sliding of the gypsum board, that is, reducing the friction damage between the gypsum board and the surface of the flip 9. In addition, when closing, when the two gypsum boards are in a vertical state, the gear shaft 6 in the first flip mechanism 2 drives the first flip mechanism 2 to slowly approach the second flip mechanism 3, avoiding the instability of the two gypsum boards during closing, which affects the closing efficiency and quality. In other words, the present invention improves the stability of flipping and closing during the production process of gypsum boards, avoids damage to the gypsum boards during the process, and improves the quality of the gypsum boards.
[0027] In the present invention, during the flipping process, the front and back sides of a gypsum board are swapped, and the gypsum board is transported from the left to the right. Before flipping, the first flipping mechanism 2 and the second flipping mechanism 3 are sunk below the surface of the gypsum board. When flipping begins, the first conveying mechanism on the left side lifts the gypsum board and rotates around the first rotation axis of the first flipping mechanism until the line formed by the first connecting rod 4 and the second connecting rod 5 forms a predetermined angle with the horizontal plane. The second flipping mechanism then rotates in the opposite direction, approaching the flap 9 of the first flipping mechanism. At this time, the curved buffer block 8 between the two bottoms prevents the gypsum board from sliding. The second flipping mechanism continues to move closer to the first flipping mechanism until both reach a working state. At this time, the gear shaft 6 rotates to translate the first flipping mechanism closer to the second flipping mechanism, so that the two flaps 9 face each other and the gypsum board is between the two surfaces. After stabilizing the gypsum board, the rotation continues, causing both flaps 9 to rotate to the right until the gypsum board contacts the conveyor surface. At this time, the gypsum board flipping is complete, and the first flipping mechanism rotates forward to return to its original sunken position.
[0028] When this embodiment is used during the closing process, the front sides of the two gypsum boards are placed opposite to each other, and the rotation process is similar to the above, except that the first flip mechanism 2 and the second flip mechanism 3 simultaneously lift a gypsum board and rotate towards each other when closing. When they reach the vertical position, the first flip mechanism is driven by the gear shaft 6 and moves horizontally close to the second flip mechanism to close the two gypsum boards. After the closing is completed, the second flip mechanism 3 descends and returns to its original position so that the two stacked gypsum boards are flattened on the conveyor belt. Similarly, the first flip mechanism 2 continues to rotate forward to return to its original sunken position, waiting for the next closing to start again.
[0029] It should be noted that it also includes a connecting rod drive, which is connected to the first connecting rod 4 and the second connecting rod 5 to adjust the angle α between the first connecting rod 4 and the second connecting rod 5, wherein 90°≤α≤180°.
[0030] In some embodiments, the preset curvature of the buffer block 8 is tangent to the bottom edge of the gypsum board, and the sum of the radius of the preset curvature and the width of the gypsum board is less than or equal to the rotation radius of the flap 9. This prevents the flap 9 from extending beyond the flap mechanism due to excessive gypsum board width when flap 9 is flipped, thereby increasing the torque of the rotating bearing and causing instability of the mechanism.
[0031] In some embodiments, as Figure 2 As shown, it also includes an anti-collision component 10 arranged on the contact surface between the flap 9 and the gypsum board. The anti-collision component 10 includes a roller and a rubber sleeve wrapped around the outside of the roller.
[0032] In this embodiment, in order to protect the surface of the gypsum board from being affected by the flap 9, a roller with a certain radius is provided on the surface of the flap 9. When there is line contact between the roller and the gypsum board, the contact area with the surface of the gypsum board is reduced, which has an excellent protective effect on the surface of the gypsum board.
[0033] In some embodiments, the plurality of flaps 9 in the first flap mechanism 2 and the second flap mechanism 3 are integrally formed. Alternatively, the first rotating shaft in the first flap mechanism 2 and the first rotating shaft in the second flap mechanism 3 are connected. This design helps improve the uniformity of the flaps and reduces the difficulty of flapping and closing the flaps.
[0034] In some embodiments, the first flip mechanism 2 and the second flip mechanism 3 are arranged in an alternating manner, wherein the first rotating shaft of the first flip mechanism 2 and the first rotating shaft of the second flip mechanism 3 are provided with an alternating concave-convex structure. The first rotating shaft of this structure facilitates the mutual movement and closing of the displaced first flip mechanism 2 and the second flip mechanism 3.
[0035] Finally, the utility model provides a stable closing device for a flip machine, comprising a bracket 1 and multiple groups of flip assemblies, the multiple groups of flip assemblies comprising a first flip mechanism 2 and a second flip mechanism 3 arranged opposite to each other, the first flip mechanism 2 comprising a gear shaft 6 arranged at the bottom end of the flip plate 9, the second flip mechanism 3 comprising a buffer block 8 comprising a preset curvature arranged at the bottom end of the flip plate 9; wherein, the first flip mechanism 2 and the second flip mechanism 3 also comprise: a first rotating shaft, a coupling, a first connecting rod 4, a second rotating shaft, a second connecting rod 5, and a mounting seat, the first rotating shaft is connected to the bracket 1, one end of the first connecting rod 4 is connected to the first rotating shaft through a coupling, the first connecting rod 4 is hinged to the second connecting rod 5, and the second connecting rod 5 is connected to the flip plate 9 through the mounting seat; the flip plate 9 of the first flip mechanism 2 and the flip plate 9 of the second flip mechanism 3 are arranged opposite to each other; the gear shaft 6 is connected to the driving gear 7 arranged on the bracket 1 through a chain, the slide rail is arranged on the bracket 1, and the bottom surface of the flip plate 9 is slidably connected to the slide rail. The utility model improves the stability of turning over and closing the gypsum boards during the production process, avoids the gypsum boards from being damaged during the process, and improves the quality of the gypsum boards.
