Description

Technical Field

[0001] The present invention relates to the field of gypsum, and particularly to an automatic vertical edge device for paper-faced gypsum boards. Background Art

[0002] Gypsum boards mainly include paper-faced gypsum boards, non-paper-faced gypsum boards, decorative gypsum boards, gypsum hollow core slabs, fiber gypsum boards, gypsum sound-absorbing boards, positioning point gypsum boards, etc. Among them, paper-faced gypsum boards are lightweight boards made with gypsum as the main raw material, incorporated with appropriate additives and fibers as the core material, and with special board paper on both sides as the face. Paper-faced gypsum boards are lightweight, high-strength, fireproof, mothproof, and easy to process. Ordinary paper-faced gypsum boards are used for interior walls, partition walls, and ceilings. Fireproof and water-resistant paper-faced gypsum boards can be used for the wall surfaces of rooms with higher humidity, such as the lining boards for tiled, metal-plated, and plastic-faced walls in bathrooms, kitchens, and bathrooms.

[0003] The main production process of gypsum boards is to mix the prepared raw materials and water, then send them into a gypsum board forming machine for laying the facing paper, applying the edge glue, and then forming. After forming, wait for it to solidify, then cut it into the required length and size, and then send it to a dryer for drying. After drying, perform trimming and edge sealing treatments, and after the treatments are completed, stack it in inventory or transport it.

[0004] During the process of forming gypsum boards, since the core material of the gypsum board is not solidified, under the influence of external forces such as gravity and unstable transportation power, the core material will shake, and then the vertical edges formed by the gypsum board will be not straight, and the vertical edges will tilt inward or outward of the core material. Especially when the production paper and slurry are laid unevenly, the fluctuation of the non-solidified core material is more obvious, and the straightness and perpendicularity of the vertical edges of the gypsum board are worse, which seriously reduces the quality of the gypsum board. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic vertical edge device for paper-faced gypsum boards, which solves the above technical problems that when the core material of the existing gypsum board is not solidified, the formed vertical edges are not straight and have poor perpendicularity due to external forces.

[0006] The technical solution adopted by the present invention is as follows:

[0007] An automatic vertical edge device for paper-faced gypsum boards includes two vertically arranged columns, a transverse driving mechanism located between the two columns and supported on the ground by the columns, and two vertical components both installed on the driving ends of the transverse driving mechanism and driven by the transverse driving mechanism to approach or move away from each other along a horizontal line.

[0008] The vertical component includes a vertical driving mechanism with one end fixed to the driving end of the horizontal driving mechanism, a horizontal plate fixed to the driving end of the vertical driving mechanism, a vertical plate vertically inserted on one side of the horizontal plate, and a spring A with two ends respectively connected to the horizontal plate and the lower surface of the horizontal plate on the vertical plate. The other end of the vertical driving mechanism faces downward, and it drives the horizontal plate to move up and down.

[0009] Among the two vertical components, the vertical plates are both located on the sides where the horizontal plates are far away from each other, and the spring A is located on the sides where the vertical plates are opposite to each other.

[0010] Further, the vertical plate is an L-shaped plate, the top of its vertical plate portion penetrates upward through the horizontal plate, and the upper and lower ends of the spring A are respectively connected to the lower surface of the horizontal plate and the horizontal straight plate portion of the vertical plate.

[0011] Further, an installation cavity is provided at the bottom of the vertical plate, and a roller is installed in the installation cavity. The wheel axles on both sides of the roller are rotatably connected to the cavity wall of the installation cavity through bearings B, and the bottom of the roller penetrates out of the installation cavity and is located outside the vertical plate. The axis of the roller is parallel to the movement track of the driving end of the horizontal driving mechanism.

[0012] Further, limiting components are installed above the horizontal plate and on both sides of the vertical plate. The top of the vertical plate penetrates above the horizontal plate, and its two side surfaces respectively contact with one limiting component.

[0013] Further, the limiting component includes a vertical plate and a bearing A rotatably installed on the vertical plate through a connecting shaft component. The inner ring of the bearing A is connected to the connecting shaft component, its outer ring is tangent to the plate surface of the vertical plate, and the axis of the bearing A is parallel to the horizontal plane.

[0014] Further, the connecting shaft component includes an installation cylinder, a nut, a spring B, a screw rod and a connecting shaft. One end of the installation cylinder is an open end and the other end is a closed end, and it is installed on the side of the vertical plate away from the vertical plate. The connecting shaft is L-shaped, its longitudinal shaft section is connected to the inner ring of the bearing A, its transverse shaft section movably penetrates through the vertical plate and then inserts into the installation cylinder, and is connected to one end of the screw rod. The other end of the screw rod movably penetrates through the closed end of the installation cylinder and is threadedly connected to the nut. The spring B is sleeved on the screw rod, and its two ends respectively abut against the closed end of the installation cylinder and the end of the transverse shaft section of the connecting shaft.

[0015] Further, a plurality of bearings A are installed on the vertical plates.

[0016] Further, the bearings A on both sides of the same vertical plate are alternately distributed in sequence along the direction perpendicular to the horizontal plane.

[0017] Further, the lateral driving mechanism includes a motor, a ball screw, and two slider bearings. Both ends of the ball screw are rotatably connected to a column through bearing B respectively, and one end of the ball screw penetrates through a column and is connected to the output shaft of the reducer through a coupling. The input shaft of the reducer is coaxially connected to the output shaft of the motor. The motor and the reducer are both installed on the base bracket, and the base bracket is installed on the column.

[0018] The thread directions at both ends of the ball screw are opposite. The slider bearings are threadedly sleeved on both ends of the ball screw, and their bottoms are respectively connected to a vertical driving mechanism.

[0019] Further, the vertical driving mechanism is a hydraulic cylinder. The bottom of its rod is fixed to the driving end of the lateral driving mechanism. The end of its piston rod faces downward and is connected to the horizontal plate.

[0020] Due to the adoption of this technical solution, the beneficial effects of the present invention are as follows:

[0021] 1. For an automatic vertical edge device for paper-faced gypsum board of the present invention, after the gypsum board is sent out from the forming machine, the vertical edges on both sides thereof are guided and limited by the vertical plates, preventing it from tilting inward or outward, improving the straightness and perpendicularity of the vertical edges of the gypsum board, and ensuring the quality of the gypsum board. At the same time, the present invention can adaptively adjust the distance between the two vertical plates according to the gypsum boards of different width dimensions so that it is consistent with the width of the produced gypsum board, rather than being limited to a certain type of gypsum board, improving the applicability of the present invention.

[0022] 2. For an automatic vertical edge device for paper-faced gypsum board of the present invention, when the thickness of gypsum boards of different models changes, not only can the position of the horizontal plate be adjusted by adjusting the vertical driving mechanism to prevent it from scratching the upper surface of the gypsum board or hindering the operation of the gypsum board, but also, through the installation method of inserting the vertical plate, the bottom of the vertical plate is always in contact with the upper surface of the conveyor belt, so that the vertical plate of the gypsum board is limited by the vertical plate from top to bottom, and the vertical edge function of the present invention will not be affected by the position adjustment of the horizontal plate. Most importantly, a spring A is arranged between the horizontal plate and the plate surface below the horizontal plate on the vertical plate, and the spring A is preferably in a compressed state, so as to stably press the vertical plate against the conveyor belt, preventing the vertical plate from floating up and down due to the fluctuation of the conveyor belt and being out of sync with the movement of the conveyor belt and unable to vertically edge stably, so that no matter how the conveyor belt fluctuates or vibrates, the bottom of the vertical plate can stably contact the conveyor belt, further ensuring the stability of the vertical edge function of the present invention.

[0023] 3. For an automatic vertical edge device for paper-faced gypsum board of the present invention, the bottom of the roller is in contact with the upper surface of the conveyor belt, so that the contact between the vertical plate and the conveyor belt is a rolling contact through the roller, thereby reducing the friction force therebetween, effectively reducing the frictional resistance, and ensuring the stability of the relevant mating parts and connecting parts.

[0024] 4. The automatic vertical edge device for paper-faced gypsum board of the present invention has a limiting component, so that the vertical movement of the vertical plate relative to the horizontal plate can only be vertical, effectively ensuring the perpendicularity of the vertical plate, and then ensuring the perpendicularity of the gypsum board vertical edge formed thereby.

[0025] 5. The automatic vertical edge device for paper-faced gypsum board of the present invention adopts conventional processing accuracy, effectively reducing the processing cost. Regarding the contact between bearing A and the vertical plate, it is effectively adjusted through the connecting shaft assembly. In this way, even if there are processing errors and assembly errors, the position of bearing A can be adjusted by adjusting the nut to make it tangent to the vertical plate, ensuring the perpendicularity of the vertical plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0034] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0035] The following will describe the present invention in detail with reference to Figures 1 to 5 the present invention.

[0036] Embodiment 1

[0037] As Figures 1 - 5 shown, an automatic vertical edge device for paper-faced gypsum board of the present invention includes two vertically arranged columns 1, a horizontal driving mechanism 2 located between the two columns 1 and supported on the ground by the columns 1, and two vertical components 3 both installed on the driving ends of the horizontal driving mechanism 2 and driven by the horizontal driving mechanism 2 to approach or move away from each other along a horizontal line;

[0038] The vertical component 3 includes a vertical driving mechanism 4 with one end fixed to the driving end of the horizontal driving mechanism 2, a horizontal plate 5 fixed to the driving end of the vertical driving mechanism 4, a vertical plate 6 vertically inserted on one side of the horizontal plate 5, and a spring A7 with both ends respectively connected to the horizontal plate 5 and the lower surface of the vertical plate 6 located below the horizontal plate 5. The other end of the vertical driving mechanism 4 faces downward and drives the horizontal plate 5 to move up and down;

[0039] In the two vertical components 3, the vertical plates 6 are both located on the sides where the horizontal plates 5 are away from each other, and the spring A7 is located on the sides where the vertical plates 6 are opposite to each other.

[0040] When using the vertical edge device involved in the present invention to perform the vertical edge operation on the gypsum board, the present invention is installed on the conveyor belt 24 at the outlet of the gypsum board forming machine. As Figure 5 shown, the driving direction of the horizontal driving mechanism 2 is parallel to the horizontal plane and perpendicular to the conveying direction of the conveyor belt 24, and the columns 1 are respectively located on both sides of the conveyor belt 24.

[0041] During automatic vertical edge, first, according to the width dimension of the gypsum board, start the horizontal driving mechanism 2, so that the vertical components installed on the driving ends of the horizontal driving mechanism 2 are driven by the horizontal driving mechanism 2, thereby adjusting the distance between the vertical components 3, so that the distance between the opposite surfaces of the vertical plates 6 between the two vertical components 3 is consistent with the width dimension of the gypsum board; then start the vertical driving mechanism 4, so that the distance between the lower surface of the horizontal plate 5 and the upper surface of the conveyor belt is consistent with the thickness dimension of the gypsum board, and since the vertical plate 6 is vertically inserted on the horizontal plate 5, its bottom contacts the upper surface of the conveyor belt.

[0042] In this way, after the gypsum board is sent out from the forming machine, the vertical edges on both sides thereof are guided and limited by the vertical plates 6, preventing it from tilting inwards or outwards, improving the straightness and perpendicularity of the vertical edges of the gypsum board, and ensuring the quality of the gypsum board. At the same time, the present invention can adaptively adjust the distance between the two vertical plates 6 according to the gypsum boards of different width dimensions so that it is consistent with the width of the produced gypsum board, and is not limited to a gypsum board of one model, improving the applicability of the present invention.

[0043] At the same time, when the thickness of gypsum boards of different models changes, not only can the position of the horizontal plate 5 be adjusted by adjusting the vertical driving mechanism 4 to prevent it from scratching the upper surface of the gypsum board or hindering the operation of the gypsum board, but also, through the installation method of inserting the vertical plate 6, its bottom is always in contact with the upper surface of the conveyor belt (when the horizontal plate 5 moves upwards, the vertical position of the vertical plate 6 remains unchanged relative to the conveyor belt, and its top moves downwards relative to the horizontal plate 5; when the horizontal plate 5 moves downwards, the vertical position of the vertical plate 6 remains unchanged relative to the conveyor belt, and its top moves upwards relative to the horizontal plate 5). In this way, the vertical plates of the gypsum board are restricted by the vertical plate 6 from top to bottom, and the vertical edge function of the present invention will not be affected by the position adjustment of the horizontal plate 5. Most importantly, a spring A is provided between the horizontal plate 5 and the plate surface below the horizontal plate 5 on the vertical plate 6, and the spring A7 is preferably in a compressed state, so as to stably press the vertical plate 6 against the conveyor belt, preventing the vertical plate 6 from floating up and down due to the fluctuation of the conveyor belt and being out of sync with the movement of the conveyor belt and unable to stably form the vertical edge, so that no matter how the conveyor belt fluctuates or vibrates, the bottom of the vertical plate 6 can stably contact the conveyor belt, further ensuring the stability of the vertical edge function of the present invention.

[0044] Embodiment 2

[0045] This embodiment further describes the vertical plate 6 on the basis of Embodiment 1.

[0046] As Figure 2 and Figure 3 shown, in the present invention, the vertical plate 6 is an L-shaped plate, the top of its vertical plate portion penetrates upwards through the horizontal plate 5, and the upper and lower ends of the spring A7 are respectively connected to the lower surface of the horizontal plate 5 and the horizontal straight plate portion of the vertical plate 6.

[0047] Since there is a large friction between the conveyor belt and the bottom of the vertical plate 6 when the conveyor belt is running, it will generate great stress on the insertion part between the vertical plate and the horizontal plate, the installation part of the horizontal plate, etc., damaging their mating or connecting parts. Therefore, an installation cavity 8 is provided at the bottom of the vertical plate 6, and a roller 9 is installed in the installation cavity 8. The axle shafts 10 on both sides of the roller 9 are rotatably connected to the cavity wall of the installation cavity 8 through bearings B11, and the bottom of the roller 9 passes through the installation cavity 8 and is located outside the vertical plate 6. The axis of the roller 9 is parallel to the movement track of the driving end of the transverse driving mechanism 2. During use, the bottom of the roller 9 contacts the upper surface of the conveyor belt, so that the contact between the vertical plate 6 and the conveyor belt becomes a rolling contact through the roller 9, thereby reducing the friction between them, effectively reducing the frictional resistance, and ensuring the stability of the relevant mating parts and connecting parts.

[0048] Preferably, the distance between the bottom of the vertical plate 6 and the upper surface of the conveyor belt is not greater than the thickness of the facing paper laid on the lower side of the gypsum board.

[0049] Embodiment 3

[0050] A description of the vertical movement of the vertical plate 6 relative to the horizontal plate 5 is as follows:

[0051] To ensure the verticality of the vertical plate 6, preferably the following implementation is adopted: Limiting components are installed above the horizontal plate 5 and on both sides of the vertical plate 6. The top of the vertical plate 6 passes above the horizontal plate 5, and its two side surfaces are respectively in contact with one limiting component.

[0052] The limiting components enable the vertical plate 6 to move vertically only up and down relative to the horizontal plate, thus effectively ensuring the verticality of the vertical plate, and then ensuring the verticality of the vertical edge of the gypsum board formed by it.

[0053] Further, the limiting component includes a vertical plate 12 and a bearing A13 rotatably installed on the vertical plate 12 through a connecting shaft assembly. The inner ring of the bearing A13 is connected to the connecting shaft assembly, its outer ring is tangent to the plate surface of the vertical plate 6, and the axis of the bearing A13 is parallel to the horizontal plane.

[0054] The contact of the vertical plate 6 is realized through the bearing A13, reducing the friction between the vertical plate 6 and the limiting component.

[0055] Further, the connecting shaft assembly includes a mounting cylinder 14, a nut 15, a spring B 16, a screw 17 and a connecting shaft 18. One end of the mounting cylinder 14 is an open end and the other end is a closed end. It is mounted on the side of the vertical plate 12 away from the vertical plate 6. The connecting shaft 18 is L-shaped. Its longitudinal shaft section is connected to the inner ring of the bearing A 13. Its transverse shaft section movably passes through the vertical plate 12 and then inserts into the mounting cylinder 14, and is connected to one end of the screw 17. The other end of the screw 17 movably passes through the closed end of the mounting cylinder 14 and is threadedly connected to the nut 15. The spring B 16 is sleeved on the screw 17, and its two ends respectively abut against the closed end of the mounting cylinder 14 and the end of the transverse shaft section of the connecting shaft 18.

[0056] Further, a plurality of bearings A 13 are mounted on the vertical plate 12.

[0057] Further, the bearings A 13 on both sides of the same vertical plate 6 are alternately distributed in sequence along the direction perpendicular to the horizontal plane, as Figures 1 - 3 shown.

[0058] In terms of dimensional processing, the higher the precision, the more the assembled device meets the design requirements. However, correspondingly, the processing cost is extremely high. Therefore, in the present invention, conventional processing precision is adopted, effectively reducing the processing cost. Regarding the contact between the bearing A and the vertical plate, it is effectively adjusted through the connecting shaft assembly. In this way, even if there are machining errors and assembly errors, the position of the bearing A 13 can be adjusted by adjusting the nut 15 to make it tangent to the vertical plate, ensuring the perpendicularity of the vertical plate.

[0059] Embodiment 4

[0060] The implementation of the lateral driving mechanism 2 is as follows:

[0061] As Figure 1 and Figure 5 shown, the lateral driving mechanism 2 includes a motor 19, a ball screw 20 and two slider bearings 21. The two ends of the ball screw 20 are respectively rotatably connected to a column 1 through bearings B, and one end of it passes through a column 1 and is connected to the output shaft of a speed reducer 22 through a coupling. The input shaft of the speed reducer 22 is coaxially connected to the output shaft of the motor 19. The motor 19 and the speed reducer 22 are both mounted on a base bracket, and the base bracket is mounted on the column 1;

[0062] The thread directions of the two ends of the ball screw 20 are opposite. The slider bearings 21 are threadedly sleeved on the two ends of the ball screw 20, and their bottoms are respectively connected to a vertical driving mechanism 4.

[0063] Embodiment 5

[0064] The first implementation of the vertical driving mechanism is as follows: The vertical driving mechanism is a hydraulic cylinder, the bottom of its rod is fixed to the driving end of the horizontal driving mechanism 2, the end of its piston rod faces downward and is connected to the horizontal plate 5.

[0065] The second implementation of the vertical driving mechanism is as follows: The vertical driving mechanism is a lead screw module, and its driving end is a sliding table threadedly sleeved on the lead screw of the lead screw module. Preferably, the sliding table is connected to the horizontal plate 5 through a connecting shaft, and the housing of the lead screw module is connected to the driving end of the horizontal driving mechanism 2.

[0066] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
