Description

Technical Field

[0001] This utility model relates to the technical field of gypsum board processing equipment, specifically to a gypsum board edge chamfering and strengthening treatment equipment. Background Technology

[0002] Gypsum board, as a commonly used material in the field of building decoration, is widely used in walls, ceilings and other scenarios due to its lightweight, sound insulation and fire resistance properties. However, the edges after cutting or forming have inherent defects: the integrity of its surface paper is destroyed, the internal gypsum core is exposed, resulting in reduced edge strength (easy to be damaged by bumps during handling or installation), and high porosity (easy to absorb environmental moisture, causing edge expansion).

[0003] In existing technologies, edge treatment of gypsum board mainly focuses on "shape adjustment" or "joint repair during construction": chamfering during the production process only changes the edge shape through chamfering devices (such as adjusting a right angle to a 45° angle), without specifically strengthening the chamfered edge - there is no penetrating material to fill the gypsum pores to improve impact resistance, nor is there any moisture-proof treatment to prevent moisture intrusion; while treatments during construction (such as filling with caulking compound and pasting with mesh tape) can only solve the problem of cracking between boards, and cannot make up for the performance defects of the edge itself during the production process.

[0004] The aforementioned defects will directly affect the usage stage: after installation, the chamfered edges are prone to coating accumulation when applying putty or paint due to their rough surface and numerous pores (caused by the corner effect, resulting in uneven paint application); or the edges may absorb moisture and expand, damaging the bonding interface between the coating and the substrate, leading to coating peeling, which seriously affects the aesthetics of the decoration and the service life of the gypsum board.

[0005] Therefore, there is an urgent need for a device that can achieve simultaneous "beveling-strengthening" processing on the production line, to solve the problem that the beveling edges are not specifically strengthened in the existing technology, and to improve the edge performance of gypsum board and the added value of the product. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a gypsum board edge chamfering and strengthening device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A gypsum board edge beveling and strengthening treatment device includes a conveyor belt for conveying gypsum board and a frame disposed on both sides of the conveyor belt; a beveling device for beveling the edges of the gypsum board is installed on the frame; a strengthening treatment mechanism for strengthening the beveled edges of the gypsum board is also installed on the frame, the strengthening treatment mechanism being located behind the beveling device, and includes a support, a conveying pump, and a hollow rotating roller; one end of the support is connected to the frame, and the other end is equipped with a motor, the output shaft of the motor being connected to one end of the hollow rotating roller to drive the hollow rotating roller to rotate; the input end of the conveying pump is connected to a strengthening liquid container, the strengthening liquid container being mounted on the frame, and the output end of the conveying pump being connected to the other end of the hollow rotating roller to input the strengthening liquid in the strengthening liquid container into the hollow rotating roller; the peripheral wall of the hollow rotating roller has micropores, and the outer peripheral surface is covered with roller bristles, allowing the strengthening liquid inside the hollow rotating roller to penetrate into the roller bristles through the micropores.

[0009] As a further embodiment of this utility model: the bracket includes a horizontal bar and a diagonal bar. One end of the horizontal bar is detachably connected to the frame by bolts. The diagonal bar is integrally formed and connected to the other end of the horizontal bar and is parallel to the chamfered surface of the gypsum board. The motor is installed on the diagonal bar. Multiple brackets are provided, and the length of the horizontal bar and the inclination angle of the diagonal bar of each bracket are different. By changing different brackets, the width and chamfer angle of the gypsum board can be adapted.

[0010] As a further embodiment of this utility model: the bracket includes a telescopic rod and a rotating plate; one end of the telescopic rod is fixedly connected to the frame, and the rotating plate is rotatably connected to the other end of the telescopic rod, with the motor mounted on the rotating plate; by extending and retracting the telescopic rod, the distance between the two hollow rollers is adjusted to accommodate the width of the gypsum board, and by rotating the rotating plate, the tilt angle of the hollow rollers is adjusted to accommodate the chamfer angle of the gypsum board.

[0011] As a further embodiment of this utility model: the output end of the delivery pump is connected to a flexible hose, and the flexible hose is connected to the center of the end face of the hollow roller through a rotary joint.

[0012] By adopting the above technical solution, this utility model will have the following beneficial effects:

[0013] This invention achieves integrated continuous operation of "beveling and strengthening" of gypsum board edges by sequentially setting a beveling device and a strengthening mechanism on both sides of the conveyor belt. This avoids the problem of separate strengthening processes required after beveling in traditional production, significantly improving production efficiency. In the strengthening mechanism, the bracket drives the hollow roller to rotate actively via a motor. A pump, in conjunction with the conveyor pump, pumps the strengthening liquid from the container into the roller. Utilizing the synergistic effect of the micropores on the roller's peripheral wall and the outer roller fibers, the strengthening liquid evenly penetrates and adheres to the beveled edge. This not only fills the exposed pores of the gypsum core to improve impact resistance but also forms a protective film at the edge to prevent moisture intrusion, effectively solving the defects of traditional beveling edges being easily damaged and prone to moisture absorption and expansion.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Reference Figure 1 and Figure 2 The gypsum board edge beveling and strengthening equipment provided in this embodiment includes a conveyor belt 1, a frame 2, a beveling device 3, and a strengthening mechanism 4. The conveyor belt 1 continuously conveys gypsum boards 5. The frame 2 is symmetrically arranged on both sides of the conveyor belt 1, and the beveling device 3 and the strengthening mechanism 4 are sequentially installed on it (the strengthening mechanism 4 is located behind the beveling device 3 and sequentially completes the beveling and strengthening processes along the gypsum board conveying direction). It should be noted that the arrangement of the conveyor belt 1, frame 2, and beveling device 3 is a conventional design for beveling in existing gypsum board production processes; detailed structure and working principle will not be elaborated here.

[0023] The specific structure of the enhanced processing mechanism 4 is as follows:

[0024] Support 41: Composed of a horizontal bar 411 and a diagonal bar 412 integrally formed. One end of the horizontal bar 411 is detachably connected to the frame 2 by bolts, and the other end is fixedly connected to the diagonal bar 412. The inclination angle of the diagonal bar 412 is parallel to the chamfered surface of the gypsum board 5. A motor 44 is fixedly installed at the end of the diagonal bar 412. Support 41 is available in various specifications, with different lengths of the horizontal bar 411 and different inclination angles of the diagonal bar 412. By changing the support 41, it can accommodate gypsum boards of different widths (500-2400mm) and chamfer angles (30°-60°).

[0025] Hollow roller 43: Connected to the output shaft of motor 44 via a coupling, and driven to rotate by motor 44. The hollow roller 43 has micropores with a diameter of 0.5-1mm (porosity 15%-20%) evenly opened on its peripheral wall, and its outer peripheral surface is covered with high-density nylon roller bristles (length 5-8mm, hardness 60-70 Shore A) to ensure that the reinforcing liquid penetrates evenly and adheres to the edge of the gypsum board.

[0026] Transfer pump 42 and strengthening liquid container 45: The transfer pump 42 is a micro gear pump with a flow rate of 5-10 mL / min. The input end of the transfer pump 42 is connected to the strengthening liquid container 45 (capacity 5L, material PP), and the output end is connected to the center of the end face of the hollow roller 43 through a hose 421 (corrosion-resistant silicone material) and a rotary joint (existing rotary seal). In this way, the hose will not rotate with the rotation of the hollow roller 43, thus avoiding tangling.

[0027] Workflow:

[0028] 1. Equipment debugging: Based on the width and chamfer angle (e.g., 45°) of the gypsum board 5, select a matching bracket 41 and fix it to the frame 2 with bolts to ensure that the roller bristles of the hollow roller 43 are in contact with the chamfered surface;

[0029] 2. Filling with reinforcing liquid: Inject reinforcing liquid (modified epoxy resin emulsion with a solid content of 30%-40%) into the reinforcing liquid container 45.

[0030] 3. Start-up: Conveyor belt 1 transports gypsum board 5 at a speed of 1-2 m / min. First, the chamfering device 3 (using a V-shaped milling cutter) completes the edge chamfering. Then, motor 44 drives hollow roller 43 to rotate at a speed of 30-50 r / min. Conveying pump 42 pumps the strengthening liquid into hollow roller 43. It penetrates to the roller hair through micropores. When the roller hair contacts the edge of the gypsum board, the strengthening liquid is evenly coated on the chamfered surface and adjacent area by capillary action, filling the pores of the gypsum core and forming a protective film. A continuous and uniform strengthening coating (thickness 0.1-0.3 mm) is formed on the edge of gypsum board 5.

[0031] 4. Continuous processing: After the gypsum board passes through step 5, the reinforcing coating cures naturally (completely cured at room temperature in 24 hours), completing the edge reinforcement.

[0032] The above key parameter ranges are: conveyor belt speed 1-2m / min, roller speed 30-50r / min, and strengthening liquid coating thickness 0.1-0.3mm. These can be adjusted according to actual production needs to ensure a balance between strengthening effect and production efficiency.

[0033] Example 2

[0034] Reference Figure 1 and Figure 3 The difference between this embodiment and embodiment 1 lies in the structural design of the bracket 41; the other components and connections are the same.

[0035] Improved structure of bracket 41:

[0036] The structure adopts a combination of telescopic rod 413 and rotating plate 414. The telescopic rod 413 is a nested stainless steel rod (stroke 0-500mm). One end of the telescopic rod 413 is welded and fixed to the frame 2, and the other end is rotatably connected to the rotating plate 414 through a rotating shaft (such as a damping rotating shaft) (rotation angle 0°-90°). The motor 44 is bolted to the rotating plate 414.

[0037] Adjustment method: The distance between the hollow rollers 43 on both sides can be changed by extending and retracting the telescopic rod 413 (manual or electric adjustment) to adapt to gypsum boards with a width of 500-2400mm; the tilt angle of the hollow rollers 43 can be adjusted (30°-60°) by rotating the rotating plate 414 around the rotating shaft to match gypsum boards with different chamfer angles, without the need to replace the bracket.

[0038] Workflow:

[0039] Except for the "equipment debugging" step, which is adjusted to adjust the position and angle of the hollow roller 43 by extending and retracting the telescopic rod 413 and rotating the rotating plate 414, the rest of the workflow is the same as in Example 1.

[0040] This invention solves the problems of low edge strength and easy moisture absorption of traditional gypsum boards through integrated "beveling and strengthening" treatment. It is suitable for the transformation of production lines for various types of paper-faced gypsum boards and fiber-reinforced gypsum boards, thereby increasing the added value of products.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
