Description

Technical Field

[0001] This utility model belongs to the technical field of trimming equipment, specifically relating to a trimming device for fireproof board production. Background Technology

[0002] Fire-resistant boards, as functional boards with fire resistance and mechanical strength, are widely used in building interiors, furniture manufacturing, and rail transit carriages. During the production process of fire-resistant boards, burrs and flash are easily left on the edges of the boards after pressing and cutting, and there are slight deviations in the cutting dimensions. If the edges are not trimmed, it will directly affect the subsequent assembly accuracy (such as excessive gaps between joints) and appearance quality (such as uneven edges). Therefore, trimming is one of the key post-processing steps in the production of fire-resistant boards.

[0003] Existing patent CN222449615U discloses a sheet metal trimming device, which transports the sheet metal through a conveyor frame 1 and clamps the sheet metal by adjusting the distance between the moving roller 403 and the fixed roller 402. However, since the sheet metal is relatively movable with respect to the conveyor frame and the moving roller 403 and the fixed roller 402, the sheet metal is very prone to shifting, moving, or even slightly twisting along the conveying direction during grinding. This causes the sheet metal to move and directly cause the trimming trajectory to deviate from the preset size, resulting in problems such as "chipped edges", "rough edges", or inconsistent trimming depth on the edge of the sheet metal.

[0004] Therefore, in order to solve the above problems, it is necessary to design an edge trimming device for fireproof board production. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0021] like Figures 1 to 7 As shown, this embodiment provides a trimming device for fireproof board production, including: A frame 1; a trimming assembly 2 symmetrically arranged within the frame 1, comprising: a grinding disc 201; wherein the grinding disc 201 is adapted to grind and trim the sides of the fireproof board when rotating; a moving assembly 3, comprising: a moving frame 301 disposed on the frame 1; wherein the moving frame 301 is adapted to support the fireproof board and move the fireproof board to the grinding disc 201; at least two fixing assemblies 4, comprising: a pressure plate 401 disposed on the moving frame 301; wherein the pressure plate 401 is adapted to fix the fireproof board; wherein the grinding disc 201 is disposed on the moving path of the moving frame 301 to grind and trim the fireproof board on the moving frame 301; wherein the pressure plate 401 is used to firmly fix the fireproof board to the moving frame 301, so as to prevent the fireproof board from shaking, shifting or moving during the grinding and trimming process of the fireproof board by the grinding disc 201 when the moving frame 301 moves the fireproof board, thus ensuring the stability and quality of the trimming process.

[0022] In this embodiment, the fireproof board to be trimmed is placed on the moving frame 301 of the moving component 3. The fireproof board is fixed to the moving frame 301 by the pressure plate 401 of the fixing component 4, ensuring that the fireproof board will not move randomly during subsequent trimming. The moving component 3 is started, and the moving frame 301 moves according to a preset path and speed, driving the fireproof board to the grinding disc 201 of the trimming component 2. When the side of the fireproof board to be trimmed comes into contact with the high-speed rotating grinding disc 201, the grinding disc 201 begins to grind and trim the edge of the fireproof board, removing burrs, flash and correcting dimensional deviations. Through the above steps, the fireproof board is prevented from shaking or shifting during the trimming process, so that the grinding disc 201 can accurately grind and trim the edge of the fireproof board, ensuring that the edge of the trimmed fireproof board is flat and smooth, and the dimensional accuracy meets the requirements. This effectively reduces the occurrence of "chipped edges" and "rough edges", ensures uniform trimming depth, and significantly improves the trimming quality of the fireproof board.

[0023] The movable component 3 further includes: a plurality of support bars 302 spaced apart within the movable frame 301; wherein each support bar 302 is movably connected to the movable frame 301; and two grinding discs 201 located within the spacing between adjacent support bars 302 or within the spacing between the support bars 302 and the movable frame 301; the movable frame 301 is adapted to allow the grinding discs 201 to move relative to each other within the spacing between adjacent support bars 302 or within the spacing between the support bars 302 and the movable frame 301 during movement; wherein the support bars 302 are provided to support the fireproof board; wherein bolted connection between the support bars 302 and the movable frame 301 is preferred to allow for flexible disassembly of the support bars 302 and better support of the fireproof board; wherein the grinding discs 201 move relative to each other within the spacing between adjacent support bars 302 or within the spacing between the support bars 302 and the movable frame 301 during movement of the movable frame 301 to prevent interference from the support bars 302.

[0024] The moving component 3 further includes: a positioning block 303 disposed on the corresponding support bar 302; wherein the positioning block 303 is adapted to position the fireproof board so that the two sides of the fireproof board are parallel to the two grinding discs 201; wherein the positioning block 303 is disposed; wherein the positioning block 303 is bolted to the corresponding support bar 302, wherein the positioning block 303 is not limited to one; wherein the positioning block 303 is not limited to a long strip shape.

[0025] The fixing assembly 4 further includes: a gantry support 402 disposed on the movable frame 301, a first cylinder 403 disposed on the gantry support 402, first guide rods 404 disposed on both sides of the top of the pressure plate 401, and a rubber plate 405 disposed at the bottom of the pressure plate 401; wherein the pressure plate 401 is connected to the telescopic end of the first cylinder 403; the first guide rods 404 pass through the gantry support 402 and are slidably connected to the gantry support 402; and the first cylinder 403 is adapted to drive the pressure plate 401 and the rubber plate 405 downward when extended, so that the rubber plate 405 presses the fireproof plate; wherein the movement of the pressure plate 41 is restricted by the first guide rods 404. The direction is such that the pressure plate 401 moves up and down vertically, preventing it from shifting, shaking, or tilting during movement, so that the rubber plate 405 can press the fireproof board firmly. The rubber plate 405 prevents direct rigid contact between the pressure plate 401 and the fireproof board surface, avoiding scratches, indentations, or other damage and ensuring the appearance quality of the fireproof board. The surface of the rubber plate 405 has a certain degree of friction, increasing adhesion between it and the fireproof board. During trimming, the rubber plate 405 can better fix the fireproof board, preventing it from sliding or shifting due to insufficient friction, ensuring the stability and quality of the trimming process.

[0026] In this embodiment, the first cylinder 403 is activated, extending its telescopic end to move the connected pressure plate 401 downwards. During this downward movement, the first guide rods 404 on both sides of the top of the pressure plate 401 slide along the gantry support 402, guiding the movement of the pressure plate 401 and ensuring its smooth and vertical downward movement. As the first cylinder 403 continues to extend, the rubber plate 405 at the bottom of the pressure plate 401 gradually approaches the fireproof board and eventually contacts its surface. The softness and elasticity of the rubber plate 405 allow it to fit tightly against the fireproof board surface. Under the pressure provided by the first cylinder 403, the fireproof board is firmly pressed against the support bar 302, achieving reliable fixation of the fireproof board.

[0027] The moving component 3 further includes: slide rails 304 disposed on both sides of the top of the frame 1, a pair of sliders 305 disposed on the slide rails 304, a first reduction motor 306 disposed on the moving frame 301, a gear 307 sleeved on the output end of the first reduction motor 306, and a rack 308 disposed on the side of the frame 1; wherein the sliders 305 are slidably connected to the slide rails 304; the top of each slider 305 is connected to the bottom of the moving frame 301; the gear 307 meshes with the rack 308; and the first reduction motor 306 is adapted to drive the gear 307 to rotate when rotating, and the gear 307 meshes with the rack 308, so that the moving frame 301 moves on the slide rails 304 through each slider 305; wherein by setting the slide rails 304 and sliders 305, precise linear guidance is provided for the movement of the moving frame 301, ensuring that the moving frame 301 can move smoothly and accurately along the predetermined path, avoiding deviation and shaking during the movement process, thereby ensuring the accuracy of the position of the fireproof board during the trimming process, which is beneficial to improving the trimming quality.

[0028] The frame 1 is provided with two sliding rods 5; the trimming assembly 2 further includes: a second reduction motor 202 connected to the grinding disc 201, a pair of sliding sleeves 203 sleeved on the sliding rods 5, a movable plate 204 disposed on the top of each sliding sleeve 203, and a bolt-type open bushing 205 disposed on the bottom of the movable plate 204; wherein the second reduction motor 202 is fixed on the movable plate 204; the sliding sleeves 203 are slidably connected to the sliding rods 5; the bolt-type open bushing 205 is sleeved on any sliding rod 5 to clamp the sliding rod 5 when the bolt is tightened; wherein the sliding rods 5 are provided to provide precise linear guidance for the movement of the trimming assembly 2.

[0029] In this embodiment, when the position of the trimming assembly 2 needs to be fixed, tightening the bolts will gradually tighten the opening of the open bushing 205, clamping the slide rod 5, thereby fixing the moving plate 204 and the entire trimming assembly 2 at the current position of the slide rod 5. When the position of the trimming assembly 2 needs to be adjusted, simply loosen the bolts, the clamping force of the open bushing 205 on the slide rod 5 will decrease, and the moving plate 204 can drive the trimming assembly 2 to slide freely on the slide rod 5. After adjusting to the appropriate position, tighten the bolts again to fix it, thereby making the position adjustment of the trimming assembly 2 more convenient and quick, improving the operational flexibility of the equipment. At the same time, it can be disassembled in conjunction with the support bar 302 so that the trimming assembly 2 can trim different edges of the fireproof board.

[0030] The trimming assembly 2 further includes: a second cylinder 206 disposed on the movable plate 204, a support plate 207 connected to the telescopic end of the second cylinder 206, and four second guide rods 208 disposed on the movable plate 204; wherein the second reduction motor 202 is fixed on the support plate 207; each of the second guide rods 208 passes through the support plate 207 and is slidably connected to the support plate 207; and the second cylinder 206 is adapted to drive the movable plate 204 to move up and down during telescopic movement, so that the second reduction motor 202... The grinding disc 201 is either higher or lower than the support bar 302; the second guide rod 208 has the same function as the first guide rod 404, which will not be described in detail here; the grinding disc 206 is driven to rise and fall by the second cylinder 206, so that the grinding disc 206 can grind and trim the fireproof board when it is higher than the support bar 302; when the grinding disc 206 is lower than the support bar 302, it can avoid injury from the grinding disc 201; at the same time, it can also adjust the position of the trimming component 2 without disassembling the support bar 302.

[0031] The trimming assembly 2 further includes: a dust suction hood 209 disposed on the side of the support plate 207; wherein the dust suction hood 209 is located on the outer half of the polishing disc 201; and the dust suction hood 209 is adapted to be connected to a vacuum cleaner pipe to suck up polishing dust.
