Description

Technical Field

[0001] The utility model relates to the technical field of gypsum board processing equipment, in particular to a gypsum board trimming device. Background Art

[0002] Gypsum board is a material made of building gypsum as the main raw material. During the gypsum board production process, it is usually necessary to use a trimming device to trim the gypsum board so that the edges of the gypsum board are repaired and smoothed.

[0003] The patent with application number CN202022532205.8 discloses a gypsum board trimmer. Through the joint action of the grinding mechanism and the reciprocating mechanism, the edges of the gypsum board can be reciprocatingly ground and trimmed without the need for workers to manually grind. Although the clamping mechanism of the patent can clamp and limit the gypsum board, making it less likely for the gypsum board to shift during the trimming process, the clamping mechanism fixes the gypsum board by vertical clamping, and the position of the clamping mechanism is fixed, it cannot adapt to gypsum boards of different sizes. At the same time, the upper surface of the support seat of the patent is a complete plane, and there is no structure to assist the movement of the gypsum board, so it is inconvenient to place the gypsum board on the support seat. Utility Model Content

[0004] In view of this, the purpose of the present invention is to provide a gypsum board trimming device to solve the problems that the existing gypsum board trimmer cannot adapt to gypsum boards of different sizes and the gypsum boards are inconvenient to place.

[0005] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0006] The cam is threadably connected to the chassis and the rollers are configured to move the cams relative to each other to move the cams to a desired location on the chassis, wherein the cams are secured to the chassis and the rollers are configured to move relative to the chassis.

[0007] As an optional solution, sleeves are provided at both ends of the support plate; guide rods are provided at both ends of the second baffle, and the two guide rods are respectively inserted into the corresponding sleeves.

[0008] As an optional solution, the reciprocating mechanism includes a screw, a first motor, a limit rod and a screw sleeve; one end of the screw is rotatably connected to the workbench; the output shaft of the first motor is connected to the other end of the screw to drive the screw to rotate; the limit rod is arranged above the workbench and parallel to the screw; one end of the screw sleeve is threadedly connected to the screw, and the other end is slidably connected to the limit rod.

[0009] As an optional solution, the trimming member includes a second motor and a cutting blade; the second motor is installed on the side of the screw sleeve facing the roller; and the cutting blade is coaxially connected to the output shaft of the second motor.

[0010] As an optional solution, a handle for rotating the screw is provided at one end of the screw away from the second baffle.

[0011] As an optional solution, it also includes a pressure wheel, a connecting frame and a spring; one end of the connecting frame is rotatably connected to the pressure wheel, and the other end of the connecting frame is rotatably connected to the screw sleeve; the spring is arranged at the angle between the connecting frame and the screw sleeve, and the two ends of the spring are respectively connected to the connecting frame and the screw sleeve so that the pressure wheel abuts against the upper surface of the edge of the gypsum board.

[0012] As an optional solution, a gasket is provided on the workbench and is located directly below the pressing wheel. The gasket extends along the reciprocating direction of the reciprocating mechanism.

[0013] Due to the adoption of the above technical solution, the utility model will have the following beneficial effects:

[0014] 1. By embedding multiple parallel rollers on the upper surface of the workbench, the gypsum board can be moved on the workbench by the rollers, which makes it convenient to place the gypsum board on the workbench; by rotating the screw, the second baffle can be driven to move toward the first baffle to clamp the gypsum board, and the nut can be tightened to fix it. Compared with the prior art that fixes the gypsum board by vertical clamping, the present invention can adapt to gypsum boards of different sizes through the horizontal clamping fixing method of the first baffle and the second baffle. Moreover, since the gypsum board tends to move along the reciprocating direction of the reciprocating mechanism during trimming, the horizontal clamping fixing method of the present invention will not cause damage to the upper and lower surfaces of the gypsum board.

[0015] 2. By setting a pressure wheel, a connecting frame and a spring, the pressure wheel is brought into contact with the upper surface of the edge of the gypsum board under the action of the spring tension, and rolls along the upper surface of the edge of the gypsum board with the screw sleeve. In this way, the pressure wheel is always in close contact with the upper surface of the edge of the gypsum board during trimming, which can reduce breakage during trimming, thereby ensuring neat trimming and improving the trimming effect of the gypsum board.

[0027] Please refer to Figure 1-6In one embodiment of a gypsum board trimming device of the present invention, the gypsum board trimming device includes a workbench 1 and a reciprocating mechanism 2, wherein the workbench 1 is a rectangular plate-shaped structure for placing the gypsum board 7 to be trimmed; the reciprocating mechanism 2 is arranged on one side of the workbench 1, and a trimming member 3 is provided on the reciprocating mechanism 2, and the reciprocating mechanism 2 can drive the trimming member 3 to perform reciprocating motion along the length direction of the workbench 1 to trim the edge of the gypsum board 7. The above arrangement belongs to the conventional design of the trimming device in the field of gypsum board processing; importantly, the gypsum board trimming device of this embodiment also includes a first baffle 41, a second baffle 42, a support plate 43 and a screw 44; wherein, the upper portion of the workbench 1 The surface is embedded with multiple rollers 11 arranged in parallel along the width direction of the workbench 1. The rollers 11 extend along the length direction of the workbench 1 and are rotatably connected to the workbench 1. The tops of the rollers 11 protrude from the upper surface of the workbench 1; the first baffle 41 and the support plate 43 are vertically welded to the other side of the workbench 1 and are respectively located at both ends of the rollers 11; the second baffle 42 is movably arranged between the first baffle 41 and the support plate 43 and is located above the rollers 11; the screw 44 passes through the middle of the support plate 43 and is threadedly connected to the support plate 43, and one end of the screw 44 is rotatably connected to the second baffle 42 through a bearing; a nut 45 is threadedly sleeved on the screw 44 and is located between the first baffle 41 and the support plate 43.

[0028] When this embodiment is in use, the gypsum board 7 can be moved on the workbench 1 by the roller 11, which makes it convenient to place the gypsum board 7 on the workbench 1; by rotating the screw 44, the second baffle 42 is driven toward the first baffle 41 to clamp the gypsum board 7, and the nut 45 can be tightened to fix it, which can limit the movement of gypsum boards 7 of different sizes along the length direction of the workbench 1.

[0029] Furthermore, sleeves 431 extending back to the second baffle 42 can be welded at both ends of the support plate 43; guide rods 421 extending toward the support plate 43 can be welded at both ends of the second baffle 42, and the two guide rods 421 are respectively moved and inserted into the corresponding sleeves 431, thereby guiding the movement of the second baffle 42.

[0030] Specifically, the reciprocating mechanism 2 includes a screw rod 21, a first motor 22, a limit rod 23 and a screw sleeve 24; one end of the screw rod 21 is rotatably connected to the workbench 1; the first motor 22 is fixedly installed on the workbench 1, and the output shaft of the first motor 22 is coaxially connected to the other end of the screw rod 21 to drive the screw rod 21 to rotate; the limit rod 23 is fixedly connected above the workbench 1 and parallel to the screw rod 21; one end of the screw sleeve 24 is threadedly sleeved on the screw rod 21, and the other end is slidably sleeved on the limit rod 23; when the first motor 22 drives the screw rod 21 to rotate forward and reverse repeatedly, the limit rod 23 limits the rotation of the screw sleeve 24, so that the screw sleeve 24 moves back and forth along the screw rod 21 under the action of the thread of the screw rod 21.

[0031] Specifically, the trimming piece 3 includes a second motor 31 and a cutting blade 32; the second motor 31 is fixedly mounted on the side of the screw sleeve 24 facing the roller 11; the cutting blade 32 is circular, and its surface is flush with the side of the edge to be processed of the gypsum board 7. The cutting blade 32 is coaxially connected to the output shaft of the second motor 31. The second motor 31 can drive the cutting blade 32 to rotate. The rotating cutting blade 32 is driven by the reciprocating movement of the screw sleeve 24 to fit the edge side of the gypsum board 7 for trimming.

[0032] Furthermore, an L-shaped handle 441 can be provided at the end of the screw 44 away from the second baffle 42. The vertical side of the handle 441 is integrally connected to the screw 44, and the horizontal side of the handle 441 extends in a direction parallel to the screw 44. The hand grips the horizontal side of the handle 441 to facilitate the rotation of the screw 44.

[0033] On the basis of the above embodiment, considering that the gypsum board 7 is relatively brittle and easily sticks and breaks during trimming, thereby affecting the trimming effect, the gypsum board trimming device of this embodiment also includes a pressure wheel 51, a connecting frame 52 and a spring 53; one end of the connecting frame 52 is rotatably connected to the pressure wheel 51, and the other end of the connecting frame 52 is rotatably connected to the screw sleeve 24; the spring 53 is arranged at the angle between the connecting frame 52 and the screw sleeve 24, and the two ends of the spring 53 are respectively connected to the connecting frame 52 and the screw sleeve 24, so that the pressure wheel 51 abuts against the upper surface of the edge of the gypsum board 7 under the action of the tension of the spring 53, so that the pressure wheel 51 is always in close contact with the upper surface of the edge of the gypsum board 7 during trimming, which can reduce breakage during trimming, thereby ensuring neat trimming and improving the trimming effect of the gypsum board 7.

[0034] Furthermore, a strip-shaped gasket 6 can be protruded from the upper surface of the workbench 1. The gasket 6 extends along the reciprocating direction of the reciprocating mechanism 2, that is, the length direction of the workbench 1. The gasket 6 is located directly below the pressing wheel 51. The height of the gasket 6 is equal to the height of the top of the roller 11 protruding from the upper surface of the workbench 1. During trimming, the gasket 6 can serve as a support for the lower surface of the edge of the gypsum board 7, and cooperate with the pressing wheel 51 to further reduce breakage during trimming.

[0035] The usage method or working principle of the utility model is as follows:

[0036] First, place one side of the gypsum board 7 on the roller 11, move it along the width direction of the workbench 1 with the help of the roller 11, and then lift the pressing wheel 51 until the edge of the side is flush with the cutting blade 32. At this time, the gypsum board 7 is completely placed on the roller 11 (as shown in FIG. Figure 3As shown), the pressing wheel 51 is then lowered so that the pressing wheel 51 cooperates with the gasket 6 to squeeze the upper and lower surfaces of the edge of the gypsum board 7, and then the screw 44 is rotated to drive the second baffle 42 to move toward the first baffle 41 to clamp the gypsum board 7 and tighten the nut 45 to fix it. Finally, the first motor 22 and the second motor 31 are started, and the first motor 22 drives the screw rod 21 to rotate forward and reverse repeatedly, and cooperates with the limit rod 23 that limits the rotation of the screw sleeve 24, so that the screw sleeve 24 moves back and forth along the screw rod 21 under the action of the thread. The reciprocating movement of the screw sleeve 24 drives the cutting blade 32 driven by the second motor 31 to rotate to fit the edge side of the gypsum board 7 for reciprocating trimming.
