Description

Technical Field

[0001] This invention relates to the technical field of paper-faced gypsum board production, specifically to a double-sided correction and adjustment paper feeding device. Background Technology

[0002] The paper feeding device for gypsum board refers to the process where the upper and lower paper surfaces are bonded to both sides of the gypsum slurry under the action of extrusion rollers, thereby forming a paper-faced gypsum board.

[0003] During the production of gypsum board, the thickness of the gypsum board produced varies depending on the application scenario. When applying paper to gypsum board of different thicknesses, the position of the pressure roller will also be adjusted accordingly. During the adjustment process, the upper paper surface may fluctuate and shift left and right as the position of the pressure roller changes. If the shift is too large, the upper paper may not be able to wrap the lower paper, resulting in leakage and defective products. In severe cases, the upper paper may even break, causing the machine to stop.

[0004] Meanwhile, during the adjustment of the squeeze roller position, the curvature of the lower paper surface remains unchanged. The larger the gap between the squeeze roller and the lower paper surface, the greater the thickness of the gypsum slurry. Once the thickness of the gypsum slurry increases, it will exceed the height of the rolled-up lower paper surface sidewall, causing the gypsum slurry to leak out from the lower paper surface sidewall. This will not only waste raw materials but also cause the equipment to stop.

[0005] In summary, the existing devices still have technical problems such as upper paper surface misalignment and lower paper surface curling degree not being able to adapt to the change in pressure roller height during the adjustment of the pressure roller height, resulting in material leakage. Summary of the Invention

[0006] The purpose of this invention is to provide a double-sided correction and adjustment paper feeding device to solve the technical problem in existing devices where the upper paper surface offsets and the lower paper surface curls to adapt to the change in the height of the pressure roller during the adjustment of the pressure roller height, resulting in material leakage.

The mounting frame is installed on both sides of the conveyor belt mounting base, and the paper feeding assembly is installed between the two mounting frames. The rotation adjustment assembly is installed on the conveyor belt mounting base, and the rotation transmission assembly is installed on the mounting frame. The tops of the two mounting frames are connected to the correction assembly.

[0016] The mounting frame has a segmented structure, and the upper section of the mounting frame rises or falls accordingly along the lower section of the mounting frame under the drive of the lifting transmission assembly.

[0017] In a preferred embodiment of the present invention, the mounting bracket includes a fixed section and a movable section, the movable section being slidably connected to the fixed section, the fixed section being fixedly connected to the side wall of the conveyor belt assembly, the bottom of the movable section having a threaded groove with one open end, the inner cavity of the fixed section being connected to the lifting transmission assembly, and the rising end of the lifting transmission assembly extending into the threaded groove.

[0018] In a preferred embodiment of the present invention, the lifting transmission assembly includes a second threaded screw, one end of which extends out of the outer wall of the two fixed sections is respectively connected to a main gear and a drive motor, and the other end of which extends into the inner cavity of the two fixed sections is fixedly connected to a main drive gear. A third threaded screw is rotatably connected to the inner cavity of the fixed section, one end of which extends out of the fixed section and into the threaded groove, and the other end of which extends into the inner cavity of the fixed section is connected to a secondary linkage gear that meshes with the main drive gear.

[0019] In a preferred embodiment of the present invention, the rotation adjustment assembly includes a fourth threaded screw that passes through the inner cavity of the conveyor belt assembly, with both ends of the fourth threaded screw extending out of the side wall of the conveyor belt assembly. A secondary gear is provided on the fourth threaded screw on the same side as the main gear, and the secondary gear is meshed with the main gear through a tooth chain. A guide seat is threadedly connected to the fourth threaded screw extending out of the side wall of the conveyor belt assembly, and a connecting rod is hinged between the guide seat and the baffle.

[0020] As a preferred embodiment of the present invention, the sides of the two baffles that are close to each other are both outwardly convex arc-shaped structures, so that the sidewalls of the lower paper are rolled up.

[0021] As a preferred embodiment of the present invention, both ends of the fourth threaded screw are provided with stops, which allow the guide seat to move within a fixed area under the blocking action of the stops.

[0022] In a preferred embodiment of the present invention, the paper feeding assembly includes a pressure roller, an upper paper surface, and a lower paper surface.

[0023] A squeeze roller is rotatably connected between the two mounting frames, and the paper is wound around the squeeze roller;

[0025] Under the rotation of the conveyor belt assembly and the extrusion roller, the lower paper surface and the upper paper surface are respectively driven to move toward the gap between the extrusion roller and the conveyor belt assembly, so that the upper paper surface and the lower paper surface are respectively attached to the periphery of the gypsum board.

[0026] In a preferred embodiment of the present invention, the correction assembly includes a fixed bracket mounted on a mounting frame, a first threaded screw rotatably connected between two fixed brackets, a drive device for driving the first threaded screw to rotate mounted on one of the fixed brackets, two correction devices threadedly connected to the first threaded screw, and an infrared sensor mounted on each of the two correction devices. The infrared sensor, the correction device, and the drive device are all electrically connected to an external control system.

[0027] Compared with the prior art, the present invention has the following advantages:

[0028] This invention monitors the degree of offset between the upper and lower paper surfaces in real time under the action of the correction component and makes timely adjustments to align and overlap the upper and lower paper surfaces. This process does not require manual adjustment and is precise. At the same time, it can detect and make timely adjustments on both sides of the upper paper surface, thereby achieving bilateral adjustment on both sides of the upper paper surface.

[0029] Meanwhile, the lifting transmission mechanism and the rotation adjustment component are linked, so that the baffle can be adjusted synchronously during the adjustment of the spacing of the extrusion roller. This allows the baffle to adjust its contact angle with the lower paper sidewall while adjusting the height of the extrusion roller, thereby reducing the possibility of material leakage during the production of gypsum board of different thicknesses.

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.

[0039] like Figure 1 As shown, conveyor belt assembly 1 is used for conveying paper-faced gypsum board;

[0040] Paper feeding assembly 21 is installed in conveyor belt assembly 1, and a gap is left between paper feeding assembly 21 and conveyor belt assembly 1 for gypsum board to pass through;

[0041] The correction component 6 is installed in the conveyor belt assembly 1 and is located above the paper feeding assembly 21. It is used to adjust the position of the paper feeding assembly 21.

[0042] The baffle 8 is hinged to the side wall of the conveyor belt assembly 1, and its end face is in contact with the paper feeding assembly 21 so that the paper feeding assembly 21 is in contact with the side wall of the gypsum board.

[0043] The lifting linkage assembly is installed on the side wall of the conveyor belt assembly 1, and its movable end is connected to the baffle 8 and the fixed end of the paper feeding assembly 21 respectively.

[0044] The lifting linkage component includes a rotation adjustment component 22 and a lifting transmission component 23. The rotation adjustment component 22 and the lifting transmission component 23 are connected by a connector. Under the driving action of the lifting transmission component 23, the rotation adjustment component 22 is driven to move synchronously, so as to adjust the contact angle between the baffle 8 and the side wall of the lower paper surface 3 while adjusting the height of the upper paper component 21.

[0045] The conveyor belt assembly 1 includes a conveyor belt mounting base 24 and a mounting frame 5. The mounting frame 5 is installed on both sides of the conveyor belt mounting base 24, and the paper feeding assembly 21 is installed between the two mounting frames 5. The rotation adjustment assembly 22 is installed on the conveyor belt mounting base 24, and the rotation transmission assembly 23 is installed on the mounting frame 5. The tops of the two mounting frames 5 are connected to the correction assembly 6. The mounting frame 5 has a segmented structure. The upper part of the mounting frame 5 rises or falls along the lower part of the mounting frame 5 under the drive of the rotation transmission assembly 23.

[0046] Furthermore, the paper feeding assembly 21 includes a pressure roller 4, an upper paper surface 2, and a lower paper surface 3.

[0047] The extrusion roller 4 is rotatably connected between two mounting brackets 5. The upper paper surface 2 is wound on the extrusion roller 4. The lower paper surface 3 is set on the surface of the conveyor belt in the conveyor belt mounting seat 24 and is attached to the lower surface of the gypsum board. Under the rotation of the conveyor belt assembly 1 and the extrusion roller 4, the lower paper surface 3 and the upper paper surface 2 are respectively driven to move towards the gap between the extrusion roller 4 and the conveyor belt assembly 1, so that the upper paper surface 2 and the lower paper surface 3 are respectively attached to the periphery of the gypsum board.

[0048] During the production of paper-faced gypsum board, the lower paper surface 3 is adhered to the conveyor belt assembly 1 under the action of the conveyor rollers, and gypsum slurry is laid onto the lower paper surface 3 under the action of the grouting equipment until the lower paper surface 3 drives the gypsum slurry to the extrusion roller 4. Under the action of the extrusion roller 4, the upper paper surface 2 is adhered to the gypsum slurry. At this time, the distance between the extrusion roller 4 and the lower paper surface 3 determines the thickness of the paper-faced gypsum board. When the upper paper surface 2 is adhered to the gypsum slurry, it is necessary to ensure that the side wall of the upper paper surface 2 and the side wall of the lower paper surface 3 can overlap. If they do not overlap, the upper paper surface 2 and the lower paper surface 3 will be misaligned during the adhesion process. Once misaligned, there is a possibility of material leakage between the upper paper surface 2 and the lower paper surface 3. Material leakage not only wastes raw materials, but also easily causes machine downtime. Therefore, when the upper paper surface 2 is adhered, it is necessary to ensure the stability of the upper paper surface 2 to prevent deviation.

[0049] Specifically, in this embodiment, such as Figure 1-2 As shown, a correction component 6 for correcting the deviation of the upper paper surface 2 is installed between the two mounting brackets 5. Under the adjustment of the correction component 6, the upper paper surface 2 is adjusted in real time to ensure that the upper paper surface 2 on the left and right sides is accurately aligned with the lower paper surface.

[0050] Among them, such as Figure 2 As shown, the correction assembly 6 includes a fixed bracket 9 mounted on the mounting frame 5. A first threaded screw 61 is rotatably connected between the two fixed brackets 9. A drive device for driving the first threaded screw 61 to rotate is mounted on one of the fixed brackets 9. Two correction devices 62 are threadedly connected to the first threaded screw 61. Infrared sensors 63 are mounted on both correction devices 62. The infrared sensors 63, correction devices 62, and drive device are all electrically connected to an external control system. When the infrared sensor 63 senses a deviation in the upper paper surface 2, the infrared sensor 63 sends a signal and feeds the signal back to the control system, so that the drive device drives the correction device 62 to move.

[0051] The adjustment process of this correction component:

[0052] When the upper paper surface 2 deviates from its designated position, the infrared sensor 63 promptly detects the degree of deviation between the upper paper surface 2 and the lower paper surface 3. Since the upper paper surface 2 has two sidewalls during its movement, both sidewalls are susceptible to deviation. Therefore, two guide devices 62 are installed on the first threaded screw 61. One guide device 62 adjusts one side of the upper paper surface 2. When one of the infrared sensors 63 detects a deviation on the corresponding side of the upper paper surface 2, the infrared sensor 63 transmits the detected deviation signal to the external control system. The external control system then feeds the signal back to the drive device, which can be a reversible motor. The drive device drives the first threaded screw 61 to rotate according to the instructions of the control system. When the first threaded screw 61 rotates clockwise, the two guides 62 located on the first threaded screw 61 move to the left simultaneously. The guides 62 drive the upper paper surface 2 to move to the left synchronously, so that the upper paper surface 2 returns to its initial position and is aligned with the lower paper surface 3. This adjustment indicates that the upper paper surface 2 is shifted to the right at this time. Conversely, when the first threaded screw 61 rotates counterclockwise, the two guides 62 located on the first threaded screw 61 move to the right simultaneously. The guides 62 drive the upper paper surface 2 to move to the right synchronously, so that the upper paper surface 2 returns to its initial position and is aligned with the lower paper surface 3. This adjustment indicates that the upper paper surface 2 is shifted to the left at this time. This allows for the detection and adjustment of both sides of the upper paper surface 2.

[0053] As for the lower paper surface 3, it is synchronized with the upper paper surface 2 in the gypsum board production process, and the main function of the lower paper surface 3 is to receive the gypsum slurry conveyed by the slurry equipment. During the conveying process of the lower paper surface 3 with the conveyor belt assembly 1, some slurry will inevitably leak out from the side wall of the lower paper surface 3. The leaked slurry will not only affect the movement of the lower paper surface 3, but also waste the slurry. Therefore, during the movement of the lower paper surface 3, the side wall of the lower paper surface 3 needs to be rolled up so that the lower paper surface 3 forms a state where the two ends are high and the middle is low.

[0054] Specifically, in this embodiment, such as Figure 1-3 As shown, baffles 8 are hinged to both sides of the conveyor belt assembly 1 located on the lower paper surface 3. Under the blocking action of the baffles 8, the side walls of the lower paper surface 3 are rolled up.

[0055] The rolled-up lower paper surface 3 can better cooperate with the upper paper surface 2 during the conveying process and wrap the gypsum slurry. At the same time, the size of the gap between the extrusion roller 4 and the lower paper surface 3 determines the thickness of the paper-faced gypsum board. If the gap between the extrusion roller 4 and the lower paper surface 3 remains unchanged, the range of thickness of the produced gypsum board will be greatly reduced. Therefore, in order to improve the production range of the device, it is necessary to consider the adjustment of the gap between the extrusion roller 4 and the lower paper surface 3.

[0056] Furthermore, such as Figure 1-2As shown, a lifting transmission assembly is provided between the two mounting brackets 5, passing through the inner cavity of the conveyor belt assembly 1. The lifting transmission assembly is driven to adjust the height of the mounting brackets 5.

[0057] Since the lifting transmission assembly mainly adjusts the height of the mounting frame 5, and the mounting frame 5 is equipped with the squeeze roller 4, the main purpose of adjusting the height of the mounting frame 5 is to adjust the height of the squeeze roller 4, thereby adjusting the distance between the squeeze roller 4 and the lower paper surface 3. Therefore, the mounting frame 5 adopts a split structure.

[0058] Specifically, in this embodiment, such as Figure 2 As shown, the mounting frame 5 includes a fixed section 51 and a movable section 52. The movable section 52 is slidably connected to the fixed section 51. The fixed section 51 is fixedly connected to the side wall of the conveyor belt assembly 1. The bottom of the movable section 52 has a threaded groove 53 with one open end. The inner cavity of the fixed section 51 is connected to the lifting transmission assembly. The rising end of the lifting transmission assembly extends into the threaded groove 53. Under the rotation of the lifting transmission assembly, the movable section 52 moves along the fixed section 51.

[0059] Among them, such as Figure 2 As shown, the lifting transmission assembly includes a second threaded screw 10. One end of the second threaded screw 10 extending out of the outer wall of the two fixed sections 51 is connected to the main gear 11 and the drive motor 12, respectively. One end of the second threaded screw 10 extending into the inner cavity of the two fixed sections 51 is fixedly connected to the main drive gear 13. A third threaded screw 14 is rotatably connected to the inner cavity of the fixed section 51. One end of the third threaded screw 14 extending out of the fixed section 51 extends into the threaded groove 53. One end of the third threaded screw 14 extending into the inner cavity of the fixed section 51 is connected to the secondary linkage gear 15, which meshes with the main drive gear 13.

[0060] The specific working process of the rotating transmission assembly:

[0061] According to the requirements of producing paper-faced gypsum board of different thicknesses, the height of the moving section 52 is adjusted by the lifting transmission assembly. Since the pressing roller 4 is connected to the moving section 52, the distance that the moving section 52 moves is the same as the distance that the pressing roller 4 moves. When adjustment is required, the drive motor 12 drives the second threaded screw 10 to rotate. The rotating second threaded screw 10 drives the two main drive gears 13 to rotate. Under the drive of the main drive gears 13, the auxiliary linkage gear 15 is driven to rotate. The auxiliary linkage gear 15 drives the third threaded screw 14 to rotate. Since the third threaded screw 14 is embedded in the fixed section 51, the moving third threaded screw 14 can drive the moving section 52 to move up or down. The two moving sections 52 are connected by the pressing roller 4, so there is no possibility of rotation. That is, when the pressing roller 4 moves upward, the distance between the pressing roller 4 and the lower paper surface 3 increases, and vice versa.

[0062] During the adjustment of the extrusion roller 4, the thickness of the gypsum slurry on the lower paper surface 3 will also change. The greater the distance between the extrusion roller 4 and the lower paper surface 3, the greater the thickness of the gypsum slurry, and vice versa. Once the thickness of the gypsum slurry increases, the height of the gypsum slurry over the rolled-up side wall of the lower paper surface 3 will be greater. Therefore, as the thickness of the gypsum slurry increases, the degree of rolling up of the lower paper surface must also be greater to avoid leakage of the gypsum slurry. At this time, the position of the baffle 8 needs to be adjusted. If manual adjustment is used, it will not only be laborious but also require stopping the machine. Considering that the adjustment of the position of the baffle 8 is related to the change of the position of the extrusion roller 4, a linkage method is adopted so that the position of the baffle 8 can be adjusted synchronously during the adjustment of the extrusion roller 4.

[0063] Specifically, such as Figure 1-2 As shown, in this embodiment, a rotation adjustment component runs through the inner cavity of the conveyor belt assembly 1 on the side away from the mounting frame 5. The rotation adjustment component and the rotation transmission component are connected by a toothed chain 7.

[0064] Driven by the lifting transmission assembly, the gear chain 7 drives the rotation adjustment assembly to move synchronously, so as to adjust the height of the mounting frame 5 and the contact angle between the baffle 8 and the side wall of the lower paper surface 3, thereby meeting the production of paper-faced gypsum board of different thicknesses.

[0065] Furthermore, such as Figure 2 As shown, the rotation adjustment assembly includes a fourth threaded screw 16, which traverses the inner cavity of the conveyor belt assembly 1, with both ends of the fourth threaded screw 16 extending out of the side wall of the conveyor belt assembly 1. A secondary gear 17 is provided on the fourth threaded screw 16 on the same side as the main gear 11, and the secondary gear 17 is meshed with the main gear 11 through a toothed chain 7. A guide seat 18 is threadedly connected to the fourth threaded screw 16 extending out of the side wall of the conveyor belt assembly 1, and a connecting rod 19 is hinged between the guide seat 18 and the baffle. Under the action of the fourth threaded screw 16 driving the guide seat 18, the angle between the baffle 8 and the conveyor belt assembly 1 is adjusted.

[0066] The synchronous movement process of the rotation adjustment component and the rotation transmission mechanism:

[0067] The lifting transmission mechanism is the source of power, while the rotation adjustment component is the driven mechanism. The second threaded screw 10 in the lifting transmission mechanism drives the main gear 11 to rotate. The main gear 11 and the secondary gear 17 are connected by a toothed chain 7. Under the drive of the toothed chain 7, the secondary gear 17 rotates synchronously with the main gear. The rotating secondary gear 17 drives the fourth threaded screw 16 to rotate. The rotating fourth threaded screw 16 drives the guide seat 18 on it to move. It can be understood that the fourth threaded screw 16 is composed of two screws of the same length but with opposite threads, and both screws are connected to the guide seat 18. Therefore, when the two guide seats 18 approach each other, the guide seats 18 push the connecting rod 19 to rotate. The moving connecting rod 19 pushes the two baffles 8 to approach each other, thereby increasing the curling degree of the lower paper surface 3. Conversely, when the two baffles 8 move away from each other, the curling degree of the lower paper surface 3 decreases.

[0068] The inner cavity of the conveyor belt assembly is equipped with a limiting rod that is parallel to the fourth threaded screw 16. The two ends of the limiting rod pass through the guide seat 18 to ensure that the guide seat 18 moves in a straight line.

[0069] Among them, such as Figure 1 and Figure 3 As shown, both ends of the fourth threaded screw 16 are provided with stop blocks 20. Under the blocking action of the stop blocks 20, the guide seat 18 moves within the fixed area, thereby reducing the possibility of the guide seat 18 slipping.

[0070] During the rotation of the two baffles 8, the baffles 8 mainly contact the lower paper surface 3, so the surface of the baffles 8 should be able to adapt to changes in the degree of curling of the lower paper surface.

[0071] Furthermore, such as Figure 3 As shown, the two baffles 8 have outwardly protruding arc-shaped structures on the sides that are close to each other, so that the side wall of the lower paper surface can be rolled up. The protruding arc-shaped structures can better fit with the lower paper surface 3, and the lower paper surface will not be damaged during the adjustment of the baffles 8.

[0072] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
