Description

Technical Field

[0001] This application relates to the technical field of building material processing equipment, and particularly to a gypsum board layered feeding and discharging mechanism. Background Art

[0002] Gypsum board is a common building material in the current construction industry. According to its functions, it can be divided into soundproof gypsum board, heat-insulating gypsum board, and fire-resistant gypsum board. During production, patterns can be printed on the surface of the gypsum board to increase its aesthetics or adhesiveness. The processing process of gypsum board generally includes processes such as gypsum mortar production, gypsum board forming, drying, inspection, and packaging. In the processes after the gypsum board is formed, the gypsum board needs to be conveyed. Due to the material of the gypsum board, vibration or jitter will cause the gypsum board to break. The existing transfer mechanisms for gypsum boards all use belt transmission, where a motor drives the belt to move, so that the gypsum boards on the belt move synchronously. However, when the dried gypsum boards are separated from the drying kiln in layers, the discharging structure is arranged in layers, forming a triangular area corresponding to the shaded part. When the gypsum board crosses this triangular area, the head edge will first contact the lower transmission mechanism, and similarly, when the tail edge reaches this triangular area, the gypsum board will quickly fall onto the lower transmission mechanism; in this kind of layered feeding and discharging mechanism, due to the height difference, it is easy to cause damage to the head and tail of the gypsum board or cause the board surface to crack. Therefore, the present utility model proposes a new layered feeding and discharging mechanism. Figure 2 As shown in the shaded part, when the gypsum board crosses this triangular area, the head edge will first contact the lower transmission mechanism, and similarly, when the tail edge reaches this triangular area, the gypsum board will quickly fall onto the lower transmission mechanism; in this kind of layered feeding and discharging mechanism, due to the height difference, it is easy to cause damage to the head and tail of the gypsum board or cause the board surface to crack.

[0028] Gypsum board is a common building material in the current construction industry. According to its functions, it can be divided into soundproof gypsum board, heat-insulating gypsum board and fire-resistant gypsum board. During production, patterns can be printed on the surface of the gypsum board to increase its aesthetics or adhesiveness. During the processing of gypsum board, the formed gypsum board needs to be conveyed in subsequent processes. Due to the material of the gypsum board, vibration or jitter will cause the gypsum board to break. The existing conveying mechanisms for gypsum board all use belt transmission, where a motor drives the belt to move, so that the gypsum board on the belt moves synchronously. However, when the dried gypsum board exits the drying kiln in layers, the discharging structure is arranged in layers, forming a triangular area as shown in Figure 2 When the gypsum board crosses this triangular area, the head edge will first contact the lower conveying mechanism, and when the tail edge reaches this triangular area, the gypsum board will quickly fall onto the lower conveying mechanism; in this kind of layered feeding and discharging mechanism, due to the height difference, it is easy to cause damage to the head and tail of the gypsum board or cause the board surface to crack. Therefore, the present utility model proposes a new layered feeding and discharging mechanism.

[0029] The following will Figures 1 to 4 describe the solution of the present utility model in detail with reference to the accompanying

[0030] As Figure 1 and Figure 2 shown, the gypsum board layered feeding and discharging mechanism provided by the present utility model includes a first conveying mechanism 1 and a second conveying mechanism 2 that are alternately docked. In the overall structure, the first conveying mechanism 1 automatically adjusts its own conveying direction according to the position of the second conveying mechanism 2.

[0031] Specifically, both the first transmission mechanism 1 and the second transmission mechanism 2 include a transmission belt 3, a driving wheel 4, a driven wheel 5, and a driving device 6. The driving device 6 is connected to the driving wheel 4, and the transmission belt 3 is sleeved on the driving wheel 4 and the driven wheel 5. The first transmission mechanism 1 further includes a fixed hinge 11, a steering cam 12, and a cam drive disposed between the driving wheel 4 and the driven wheel 5. The steering cam 12 abuts against an auxiliary shaft 51 of the driven wheel 5 of the first transmission mechanism 1, and the cam drive drives the steering cam 12 to rotate so that the driven wheel 5 of the first transmission mechanism 1 moves along a preset trajectory.

[0032] First, during the transmission process, the self-weight of the gypsum board is utilized to move the driven wheel 5 of the first transmission mechanism 1 downward to a position where it is docked with the second transmission mechanism 2. Because during the transmission process, the closer the gypsum board is to the driven wheel 5 of the first transmission mechanism 1, the greater the force on the driven wheel 5. Under the soft restraint of the fixed hinge 11, the overall transmission direction of the first transmission mechanism 1 changes.

[0033] In addition, during the transmission of the gypsum board, by monitoring the moving position of the gypsum board, when the preset position is satisfied, the first transmission mechanism 1 is adjusted to move downward or upward to align with the second transmission mechanism 2 at a lower or higher position.

[0034] Specifically, an angle detector and a controller are provided in the first transmission mechanism 1. The angle detector is electrically connected to the controller, and the controller is signal-connected to the cam drive. The angle detector detects the angle α between the line connecting the axis of the driven wheel 5 of the first transmission mechanism 1 and the axis of the driving wheel 4 of the second transmission mechanism 2 and a preset reference. The controller outputs control parameters for the cam drive according to the angle α and sends them to the cam drive. Specifically, when the angle α is greater than zero, the steering cam 12 is controlled to reverse, and when the angle α is less than zero, the steering cam 12 is controlled to rotate forward.

[0035] As described above, on the first transmission mechanism 1, when the gypsum board on the transmission belt 3 reaches the preset position, the angle detector starts to detect the angle α between the transmission surface of the driven wheel 5 of the second transmission mechanism 2 and the transmission surface of the first transmission mechanism. If the angle α is greater than zero, it means that the second transmission mechanism 2 is relatively higher than the first transmission mechanism 1, and the cam drive is controlled to reverse the steering cam 12 to increase the position of the first transmission mechanism 1; otherwise, the cam drive is controlled to rotate the steering cam 12 forward to lower the position of the first transmission mechanism 1. Here, the angle detector can adopt a laser testing device to improve the accuracy and speed of testing.

[0036] In summary, during the transmission of the gypsum board, the self-weight of the gypsum board or the moving position of the gypsum board is utilized to adjust the transmission direction of the transmission mechanism, so that the height difference between the transmission mechanism in operation and the transmission mechanism to be docked is zero or reduced to a height that is not sufficient to damage the gypsum board, effectively avoiding possible damage to the head end, tail end, or the board body of the gypsum board during the transmission process and improving the conveying quality of the transmission mechanism.

[0037] It should be noted that the radian and size specifications of each curved surface of the aforementioned steering cam 12 are related to the actual parameters of the actual first transmission mechanism 1 and the second transmission mechanism 2. In this embodiment, no specific limitations are imposed on its shape, size, etc.

[0038] In some embodiments, the gypsum board layered feeding and discharging mechanism provided by the present utility model further includes a correction mechanism. The correction mechanism includes a photoelectric detector, a correction drive, and a correction member. The photoelectric detector is signal-connected to the controller, the controller is electrically connected to the correction drive, the correction drive is connected to the correction member, and the correction member is connected to the driven wheel 5.

[0039] In this embodiment, in order to avoid the problem of the conveyor belt 3 running off track after the first transmission mechanism 1 adjusts the transmission direction, or the problem of the gypsum board running off track when the second transmission mechanism 2 is docked with the first transmission mechanism 1, by setting the correction mechanism, the position and angle of the driven wheel 5 are adjusted by controlling the action of the correction member to solve the problem of the gypsum board running off track. Specifically, a photoelectric detector is used to detect whether the gypsum board runs off track and whether the driven wheel 5 is displaced at the same time. Then, according to the detection results, the controller is used to drive the correction member to act. In this embodiment, no specific limitations are imposed on the structure of the correction member, as long as it can push the gypsum board and move the driven wheel 5.

[0040] In some embodiments, as Figure 3 shown, it further includes a transition member 7. The transition member 7 includes a rotating shaft 71 and a support plate 72 with a triangular cross-section. The rotating shaft 71 is sleeved in the hole at the center of the longest hypotenuse of the triangular support plate 72. One short side of the triangular support plate 72 is horizontal with the conveyor belt 3 of the first transmission mechanism 1, and the second short side of the triangular support plate 72 is between the conveyor belt 3 of the first transmission mechanism 1 and the conveyor belt 3 of the second transmission mechanism 2.

[0041] As Figure 4 shown, the transition member 7 includes a rotating shaft 71 and a first support column 8 and a second support column 9 that form an included angle with each other. One end of the first support column 8 and the second support column 9 is hinged, the rotating shaft 71 passes through the hinged position, the first support column 8 is horizontal with the conveyor belt 3 of the first transmission mechanism 1, and the second support column 9 is between the conveyor belt 3 of the first transmission mechanism 1 and the conveyor belt 3 of the second transmission mechanism 2.

[0042] In some embodiments, Teflon rubber pads are attached to the peripheries of the driving wheels 4 and the driven wheels 5 on the aforementioned first transmission mechanism 1 and second transmission mechanism 2. The feeding ends of the first transmission mechanism 1 and the discharging ends of the second transmission mechanism 2 both include feeding tongues 10. The feeding tongues 10 are clamped with the driving wheels 4 of the first transmission mechanism 1, and the feeding tongues 10 are clamped with the driven wheels 5 of the second transmission mechanism 2.

[0043] In this embodiment, the Teflon rubber pad can not only prevent slipping and friction, but also the relatively thick Teflon can play a buffering role when contacting the gypsum board, further reducing the damage of the transmission mechanism to the gypsum board. In addition, the feeding tongue 10, that is, an extension mechanism at the front or rear end of the front end of the conveyor belt 3, plays a role in transitioning or supporting the gypsum board, and some soft materials such as asbestos board and rubber board can be used.

[0044] Finally, a gypsum board layered feeding and discharging mechanism provided by the present utility model includes a first transmission mechanism 1 and a second transmission mechanism 2 that are alternately docked, and the first transmission mechanism 1 automatically adjusts its own transmission direction according to the position of the second transmission mechanism 2;

[0045] Both the first transmission mechanism 1 and the second transmission mechanism 2 include a conveyor belt 3, a driving wheel 4, a driven wheel 5, and a driving device 6. The driving device 6 is connected to the driving wheel 4, and the conveyor belt 3 is sleeved on the driving wheel 4 and the driven wheel 5; the first transmission mechanism 1 further includes a fixed hinge 11, a steering cam 12, and a cam drive disposed between the driving wheel 4 and the driven wheel 5. The steering cam 12 abuts against an auxiliary shaft 51 of the driven wheel 5 of the first transmission mechanism 1 (the auxiliary shaft 51 is coaxial with the driven wheel 5), and the cam drive drives the steering cam 12 to rotate so that the driven wheel 5 of the first transmission mechanism 1 moves along a preset trajectory. The present utility model effectively avoids possible damage to the head end, tail end or plate body of the gypsum board during the transmission process, improves the conveying quality of the transmission mechanism, and improves the practicability of the gypsum board transmission mechanism.
