Description

Technical Field

[0001] The utility model relates to the technical field of fireproof board production, in particular to an edge and corner trimming device for fireproof board production. Background Art

[0002] Fireproof board, also known as fire-resistant board, is scientifically called thermosetting resin impregnated paper high-pressure laminate. It is a fire-resistant building material for surface decoration, with rich surface colors, textures and special physical properties. Fireproof board is widely used in interior decoration, furniture, kitchen cabinets, laboratory countertops, exterior walls and other fields. However, when producing fireproof board, it is generally produced by extrusion, but after the production, there will be bumps on the side of the fireproof board, which is not convenient for later use, so the bumps will be removed by cutting;

[0003] In the prior art, a utility model patent with a publication number of CN220074762U is disclosed, which relates to the technical field of fireproof board production, including a workbench, on which raw materials are placed, and a trimming mechanism is installed on the rear side of the upper end of the workbench, and the trimming mechanism fits the raw materials. In the utility model, the user places the raw materials on the surface of the workbench, so that the side of the raw materials to be processed is located at the upper end of the groove, and then the motor controls the movement of the L-shaped fixing block and the connecting plate through the thread, so that it drives the blade to trim and cut the protrusions on the side of the raw materials, and then the cut waste will fall into the inside of the groove, and the cleaning plate will push it, so that the excess protrusions and burrs on the surface of the raw materials can be quickly cleaned, and at the same time, there is no need for secondary processing at a later stage, which greatly improves the production efficiency of the raw materials;

[0004] However, when the above solution is in use, it utilizes clamping limits in the up and down directions, and improper control of the clamping pressure can easily cause damage to the board. In addition, the fireproof board is directly placed on the table, and there is no gap between its bottom and the table. The subsequent removal of the fireproof board or the switching of sides is troublesome. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a corner trimming device for fireproof board production. Compared with the prior art, the trimming device uses negative pressure limiting to limit the position, thereby avoiding damage to the board body. In addition, it is also convenient for unloading the board body and turning the edge.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0012] Preferably, the electromagnet attracts the adjacent surface of the magnetic piston anisotropically after being energized.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] By using support columns and limiting mechanisms, the fireproof board is limited by negative pressure difference. Compared with the pressurized limiting method in the prior art, this method causes less damage.

In addition, the trimming part can be moved forward or backward for trimming, which effectively improves the trimming efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-Figure 3 , a corner trimming device for fireproof board production, comprising a platform 1, an L-shaped plate 4 is fixedly connected to the upper end of the platform 1, and a slide groove 11 is opened at the lower end of the L-shaped plate 4;

[0021] The supporting mechanism also includes a plurality of supporting columns 3 fixedly connected to the upper end of the platform 1, and each supporting column 3 is provided with a columnar groove 2;

[0022] The trimming mechanism includes a connecting strip 6 fixedly arranged below the horizontal portion of the L-shaped plate 4, the front and rear sides of the connecting strip 6 are fixedly connected to a first blade 7, the left side of the connecting strip 6 is fixedly connected to two mounting strips 9, and the front and rear sides of each mounting strip 9 are fixedly connected to a second blade 10;

[0023] The movable mechanism is used to move the connecting strip 6 forward and backward. The movable mechanism includes a threaded rod 12 rotatably connected between the front and rear inner walls of the slide groove 11. A slider 13 is threadedly connected to the threaded rod 12. The slider 13 is slidably connected to the inner wall of the slide groove 11. The lower end of the slider 13 is fixedly connected to the upper end of the connecting strip 6. The output shaft of the motor 5 is a servo motor that can change the rotation direction.

[0024] Among them, it also includes multiple limiting mechanisms, which are respectively located in the corresponding columnar grooves 2. The limiting mechanisms include an electromagnet 16 fixedly connected to the bottom of the columnar groove 2. A magnetic piston 14 that can slide up and down is arranged in the columnar groove 2. The lower end of the magnetic piston 14 is elastically connected to the electromagnet 16 through a spring 15. The inner bottom of the columnar groove 2 is connected to the outside through a connecting port 8. After the electromagnet 16 is energized, it is anisotropically attracted to the adjacent surface of the magnetic piston 14.

[0025] In the utility model, when in use, the fireproof board is placed on the upper end of the support column 3, and then multiple electromagnets 16 are started and energized, so that the magnetic piston 14 moves downward and compresses the corresponding spring 15, stretching the gas in the top space of the columnar groove 2 to reduce its pressure, thereby limiting the fireproof board by using the negative pressure difference. Compared with the pressurized limiting method in the prior art, this method causes less damage, and due to the use of the support column 3, there is a large gap between the lower end of the fireproof board and the upper end of the platform 1, which facilitates the subsequent operation of picking it up and rotating it;

[0026] After completing the limit, start the motor 5 to rotate, drive the threaded rod 12 to rotate, and let the slider 13 move from front to back (the slider 13 is at the frontmost side at this time), and use the first blade 7 and the two second blades 10 on the rear side to move backward to trim the edges and corners of the fireproof board. The trimmed debris falls directly to the upper end of the platform 1. The limit is subsequently released, and then the side of the fireproof board is changed. Then start the motor 5 to rotate in the opposite direction to trim the other side. If this method is performed multiple times, the four sides of the fireproof board can be trimmed.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
