Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are also within the scope of the application.

As shown in fig. 1, 2, 3 and 4, the gypsum board cutting device disclosed by the application comprises a bottom supporting platform 1, wherein a horizontal placing beam 2 is arranged above the bottom supporting platform 1, one side of the horizontal placing beam 2 is connected with a height adjusting unit 3, and the height adjusting unit 3 can adjust the position of the horizontal placing beam 2 in the vertical direction;

a cutting knife group 4 is arranged above the horizontal placing beam 2, the lower end of the cutting knife group 4 is connected with a moving assembly 5, and the moving assembly 5 can drive the cutting knife group 4 to move along the length direction of the horizontal placing beam 2;

the cutting knife group 4 includes two cutting blades 41 that beam 2 length direction symmetry set up along the level, and the mutual near side of two cutting blades 41 is cutting edge portion, and the minimum distance between two cutting blades 41 is less than the thickness of gypsum board, and two cutting blades 41 middle zone's one end is equipped with the shovel sword of polishing 42, and two cutting blades 41 are installed respectively on the both sides wall of shovel sword 42 width direction of polishing, and shovel sword 42 length direction's both ends all are equipped with cutting edge portion, and the upper and lower both sides of shovel sword 42 blade section are crude frosting 43.

In the above embodiment, as shown in fig. 3, the upper side of the horizontal placement beam 2 of the present application may be provided with a notch, so that a certain limit effect is provided for the gypsum board when the gypsum board is placed thereon, avoiding the gypsum board from sliding off the surface of the horizontal placement beam 2 during the cutting process, and since the specifications of the conventional gypsum board are generally uniform, the width of the notch provided on the horizontal placement beam 2 may be slightly larger than the thickness of the conventional gypsum board, so that even when there is a small deviation in the thickness of the gypsum board, the gypsum board may be placed in the notch provided on the horizontal placement beam 2.

As shown in fig. 4, the edge portion of the cutting blade 41 of the present application extends to the adjacent direction of both ends thereof, so that the area of the edge portion of the cutting blade 41 can be increased, and the resistance of the cutting blade 41 to scoring on the plasterboard can be made smaller. When the plasterboard is placed on the horizontally placed beam 2, before the cutting blade set 4 performs cutting operation on the plasterboard, the plasterboard at this time is located right in front of the middle area of the two cutting blades 41, the grinding blade 42 having a width slightly larger than the thickness of the plasterboard is located right behind the middle area of the two cutting blades 41, and the edge portion of one end of the grinding blade 42 is right against the plasterboard. Thus, when the cutting blade set 4 cuts the gypsum board, the two cutting blades 41 will first score the front and back sides of the gypsum board, and the grinding blades 42 located behind them will then further process the scored areas of the gypsum board.

The grinding shovel blade 42 is made of metal, the rough grinding surfaces 43 on the upper side and the lower side of the grinding shovel blade are integrally formed, and the concrete structure is similar to the file on the surface of the file, so that the grinding shovel blade has a good grinding effect when the grinding file moves along the notch of the gypsum board, and the service life of the grinding shovel blade is long.

When a worker needs to cut the plasterboard, the position to be cut may be marked on the plasterboard, then the lower end of the plasterboard is put on the horizontally placed beam 2, and then the height adjusting unit 3 is started to adjust the position of the marking line on the plasterboard until it is at the same height as the blade edge portion of the cutting blade 41 in the cutting blade group 4. The worker can then hold the upper end of the plasterboard in a vertical state by holding it in a hand, and then activate the moving unit 5, and the moving unit 5 can move the cutting blade set 4 toward the plasterboard, because the minimum distance between the edge portions of the two cutting blades 41 of the present application is smaller than the thickness of the plasterboard, when the two cutting blades 41 pass through both sides of the plasterboard simultaneously, scores can be left on the surface of the plasterboard, the edge portions of the grinding blades 42 located immediately behind the two cutting blades 41 can contact the scored areas on the plasterboard, and the scored positions can be undercut, and the rough frosted surface 43 on the grinding blades 42 can automatically grind the cut positions of the cut plasterboard.

Compared with the technical proposal that in the prior art, a worker scores one side of the gypsum board along the marking line and then scores the other side of the gypsum board, then breaks the gypsum board along the scores, and the broken parts of the gypsum board need to be polished by sand paper. The cutting knife group 4 can simultaneously complete the working contents in the prior art by only moving once along the marked lines on the gypsum board, so that the gypsum board cutting device greatly improves the effect of workers on cutting the gypsum board, and particularly can remarkably improve the working speed when working on buildings with large gypsum board consumption.

Further, as shown in fig. 4, 5 and 6, the two cutting blades 41 are disposed at an angle, and the distance between the two cutting blades 41 near one end of the grinding blade 42 is smaller than the distance between the other ends of the two cutting blades 41.

In the above embodiment, the two cutting blades 41 of the present application are designed to form an included angle, so that the cutting edge of the cutting blade 41 can cut into the plasterboard rapidly when the cutting blade 41 is used for scribing the plasterboard, which not only can reduce the resistance of the cutting blade 41 when the cutting blade is used for scribing along the marking line on the plasterboard, but also can improve the smoothness of the cut of the scribed plasterboard.

Further, as shown in fig. 4 and 5, one end of each of the two cutting blades 41, which is close to the grinding blade 42, is fixedly connected with a handle 6, and one side, which is close to each other, of each of the two handles 6 is hinged with two side walls of the grinding blade 42 in the width direction through a bracket 7; the knife handle 6 is fixedly connected with a mounting plate 8 on the lower side of the bracket 7 at the corresponding position, the two mounting plates 8 are fixedly connected through a first spring 9, and the elastic force generated when the first spring 9 deforms can drive the knife handle 6 to rotate around the hinge point of the knife handle and the bracket 7.

In the above embodiment, the two first springs 9 of the present application can keep a certain included angle between the two cutting blades 41 in the initial state, when the two cutting blades 41 of the present application start to scribe on the plasterboard, the cutting blades 41 will be rotated by a certain angle against the plasterboard in a direction away from the plasterboard, at this time, the handle 6 fixedly connected with the cutting blades 41 will deform with the first springs 9 on the lower side thereof, and the elasticity generated after the deformation of the first springs 9 will maintain the cutting blades 41 to scribe a certain depth on the plasterboard. When the thickness of the gypsum board fluctuates, for example, when the thickness of the gypsum board increases, if the included angle between the two cutting blades 41 does not change, the resistance to the cutting process of the cutting blades 41 increases, so that the cutting blades 41 are easily damaged, and when the two cutting blades 41 meet the same condition, the included angle between the two cutting blades 41 is adjusted under the action of the first spring 9, so that the cutting blades 41 are ensured to score the score with the proper depth on the surface of the gypsum board.

Meanwhile, as some gypsum boards possibly contain some hard lumps in the gypsum board during the preparation process, when encountering the hard lumps, the cutting blade 41 of the application has certain obstacle avoidance capability under the action of the first spring 9, so that the service life of the cutting blade 41 is prolonged.

Further, as shown in FIG. 6, the overall width of the sanding blade 42 is greater than the maximum thickness of the gypsum board.

In the above embodiment, the polishing shovel blade 42 according to the present application is provided in the above-described manner, so that on one hand, the polishing shovel blade 42 can be ensured to cut thoroughly along the marked line of the plasterboard, and on the other hand, the rough frosted surface 43 on the polishing shovel blade 42 can be ensured to polish the cut-up and cut-down positions of the plasterboard comprehensively, and the polishing effect is ensured.

In the above embodiment, the hydraulic cylinder 32 of the present application can be simultaneously connected to both ends of the horizontally placed beam 2 by the U-shaped lifting frame 31, and the horizontally placed beam 2 can be kept in a horizontal state all the time during the movement. When the position of the gypsum board on the horizontally placed beam 2 in the vertical direction needs to be adjusted, the hydraulic cylinder 32 can be started, and the height of the gypsum board on the horizontally placed beam 2 can be adjusted through the U-shaped lifting frame 31 by adjusting the expansion and contraction amount of the output end of the hydraulic cylinder, so that the marking point on the gypsum board is level with the height of the cutting knife group 4. The height adjusting unit 3 of the present application is not only convenient to operate, but also the adjusting process is sufficiently smooth.

Further, as shown in fig. 1 and 2, two guide rods 10 are penetrated through the closed end of the U-shaped lifting frame 31, the U-shaped lifting frame 31 can move up and down along the two guide rods 10, and the axes of the two guide rods 10 are symmetrical about the axis of the hydraulic cylinder 32; the lower ends of the two guide rods 10 are fixedly connected with the bottom supporting platform 1.

In the above embodiment, the two guide rods 10 arranged on the U-shaped lifting frame 31 can further ensure the stability of the U-shaped lifting frame 31 when driven by the hydraulic cylinder 32 to move with the horizontal placement beam 2.

Further, as shown in fig. 1, both ends of the horizontally placed beam 2 are fixedly connected with the open ends of the U-shaped lifting frame 31 by the second springs 11.

In the above embodiment, in order to prevent the gypsum board from being inclined to affect the cutting accuracy in the process of cutting the gypsum board, it is generally necessary to hold the gypsum board by a worker while the grinding blade 42 has a certain thickness, and when the grinding blade 42 cuts into the gypsum board, the overall height of the gypsum board is easily changed, and if the worker does not release the gypsum board at all, the grinding blade 42 easily causes edge breakage at the cut of the gypsum board. Because the U-shaped lifting frame 31 is connected with the horizontal placing beam 2 for placing the gypsum board through the second springs 11, when the height change of the gypsum board is easily dissolved by the second springs 11, the edge breakage at the notch can be effectively avoided when the grinding shovel blade 42 cuts into the marked line of the gypsum board.

Further, as shown in fig. 2 and 6, two adjusting columns 12 are arranged on one side of the horizontally placed beam 2 close to the U-shaped lifting frame 31, the lower ends of the adjusting columns 12 are fixedly connected with the bottom supporting platform 1, a plurality of adjusting holes 13 are uniformly formed in the column body of the adjusting columns 12 along the axial direction, and a clamping frame 14 is fixedly connected to one of the adjusting holes 13 through bolts and nuts; the inner side of the clamping frame 14, which is far away from one end of the adjusting upright post 12, is provided with a circular clamping plate 15, one side of the circular clamping plate 15, which is far away from the adjusting upright post 12, is fixedly connected with one end of a threaded knob 16, and the other end of the threaded knob 16 penetrates through the clamping frame 14, which is far away from one end of the adjusting upright post 12, and is in threaded connection with the adjusting upright post 12.

In the above embodiment, the two adjusting columns 12 of the application are installed on one side of the horizontally placed beam 2 close to the U-shaped lifting frame 31, so that the space at the opening of the U-shaped lifting frame 31 can be effectively utilized. The clamping frame 14 is E-shaped and consists of three parallel short rods and a long rod, wherein one end of the short rod can be arranged on an adjusting hole 13 of the adjusting upright post 12 through bolts and nuts so as to improve the contact area between the clamping frame 14 and the adjusting upright post 12; the threaded section of the threaded knob 16 extends through and is threadedly connected to a short rod at the other end of the clamping frame 14, which end of the clamping frame 14 can provide a mounting base for the threaded knob 16; the circular clamping plate 15 of the application is arranged between the short bar in the middle of the clamping frame 14 and the short bar at the end remote from the adjusting upright 12 and is connected with the threaded section of the threaded knob 16.
