DETAILED DESCRIPTION
[0022] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.
[0023] Embodiment 1
[0024] In this embodiment, a decorative gypsum board trimming device is provided, such as Figure 1 As shown, it includes an operating table 1, on which legs are fixedly connected, and a support plate 2 for supporting a gypsum board and driving the gypsum board to move is installed on the operating table 1. When in use, the gypsum board to be trimmed is placed on the support plate 2, and then the support plate 2 can drive the gypsum board to move on the operating table 1. An adjustment table 3 is also symmetrically installed on the operating table 1. The two adjustment tables 3 are symmetrical to each other with the center line of the operating table 1 as a reference. The adjustment tables 3 are slidably connected to the operating table 1 through a slide rail fixedly connected to the operating table 1, and the adjustment table 3 is fixedly connected to the output rod of an electric push rod 20. The electric push rod 20 is also installed on the operating table 1. The position of the adjustment table 3 can be controlled by controlling the extension and retraction of the output rod of the electric push rod 20. A cutting assembly for cutting the gypsum board and a grinding block 4 for grinding the position of the gypsum board after cutting are installed on the two adjustment tables 3. The grinding block 4 is located as shown in the figure. Figure 2As shown on the right side, when the gypsum board moves, it will first pass through the cutting assembly to be trimmed, and then contact with the grinding block 4. By controlling the position of the adjustment table 3, the cutting assembly on it can trim the gypsum boards of different sizes, and the grinding block 4 can grind the trimmed gypsum board;
[0025] During the assembly process, the height of the cutting assembly and the grinding block 4 can be adjusted to make the utility model suitable for gypsum boards of different thicknesses.
[0026] like Figure 5 As shown, a fixing rod 5 is fixedly connected to the lower side of the support plate 2, and the fixing rod 5 is slidably connected to the slide groove 6 opened on the operating table 1. The fixing rod 5 can drive the support plate 2 to slide back and forth along the groove wall of the slide groove 6 on the operating table 1. The fixing rod 5 is meshedly connected with a screw rod 7 rotatably connected to the inside of the slide groove 6. The screw rod 7 is driven by a driving motor 8. The rotation of the screw rod 7 can make the fixing rod 5 slide back and forth inside the slide groove 6. One end of the screw rod 7 passes through the operating table 1 and extends to the outside of the operating table 1, and is interconnected with the motor shaft of the driving motor 8 through a synchronous belt. The rotation of the motor shaft of the driving motor 8 can drive the screw rod 7 to rotate.
[0027] like Figure 2 As shown, the cutting assembly includes a pre-cutting motor 9 and a cutting motor 10, which are respectively mounted on the adjusting table 3 through a motor seat, a pre-cutting blade 11 is mounted on the motor shaft of the pre-cutting motor 9, and a cutting blade 12 is mounted on the motor shaft of the cutting motor 10, the size of the pre-cutting blade 11 is smaller than the size of the cutting blade 12, the lowest point of the pre-cutting blade 11 is higher than the lower side of the gypsum board, and the lowest point of the cutting blade 12 is lower than the lower side of the gypsum board, the pre-cutting blade 11 will open a groove on the upper side of the gypsum board, so that the cutting effect of the cutting blade 12 is better, and the pre-cutting blade 11 is close to the initial position of the adjusting table 3, as shown in FIG. Figure 2 The pre-cutting blade 11 is shown to be located on the left side of the cutting blade 12 . At this time, when the gypsum board moves from left to right, the gypsum board will first contact the pre-cutting blade 11 and then contact the cutting blade 12 .
[0028] like Figure 3 and Figure 4 As shown, the grinding block 4 is installed on a base plate 13, and the base plate 13 is slidably connected to the inside of a fixed frame 14, and a spring 15 is connected between the base plate 13 and the inner wall of the fixed frame 14, one end of the spring 15 is fixedly connected to the base plate 13, and the other end is fixedly connected to the inner wall of the fixed frame 14, and the spring 15 has a pressing force to press the fixed frame 14 toward the gypsum board. Under the action of the pressing force of the spring 15, the grinding block 4 will apply a pressing force to the gypsum board, so that the grinding block 4 can grind the position after the gypsum board is trimmed.
[0029] The grinding block 4 is funnel-shaped, and its conical surface is covered with a grinding layer. The grinding block 4 can grind gypsum boards within a certain thickness range, that is, the thickness of the gypsum board is greater than the distance between the inner ends of the two conical surfaces and less than the distance between the outer ends of the two conical surfaces. At the same time, the center line of the gypsum board and the midpoint of the grinding block 4 are on the same horizontal plane (such as Figure 2 As shown), the grinding block 4 is rotatably connected to the base plate 13, and the grinding block 4 will rotate when grinding the gypsum board, so that the gypsum board can be evenly grinded.
[0030] like Figure 1 As shown, the adjusting table 3 is equipped with a linear laser emitter 16 through a bracket fixedly connected thereto. The laser emitter 16 can project a straight line on the operating table 1, which can facilitate the staff to adjust the position of the adjusting table 3 so that the pre-cutting blade 11 and the cutting blade 12 are aligned with the cutting line drawn in advance on the gypsum board, making the cutting more accurate.
[0031] A through hole 17 is provided between the two adjustment tables 3 and on the table top of the operating table 1. The length of the fixing rod 5 is greater than that of the through hole 17. The setting of the through hole 17 will not affect the sliding of the fixing rod 5. A receiving frame 18 is installed below the through hole 17 and on the operating table 1. The waste generated by trimming will directly fall into the receiving frame 18 through the through hole 17, which can not only prevent the waste generated by trimming from affecting the subsequent cutting work, but also facilitate the staff to collect the cutting waste.
[0032] The support plate 2 is provided with a plurality of rubber bumps 19 for increasing the friction between the support plate 2 and the gypsum board. The provision of the rubber bumps 19 can prevent the gypsum board from sliding on the support plate 2 during cutting, thereby affecting the edge cutting work.
[0033] In order to achieve better display effect, Figure 1 and attached Figure 5 The thread of the screw rod 7 is not shown.
[0034] The drive motor 8, pre-cutting motor 9, cutting motor 10 and electric push rod 20 are respectively connected to the external power supply through cables. The start and stop of the drive motor 8, pre-cutting motor 9, cutting motor 10 and electric push rod 20 can be controlled by controlling the on and off of the power supply.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or replaced by equivalents. Any modification or partial replacement that does not depart from the spirit and scope of the present invention should be included in the scope of the claims of the present invention.
