DETAILED DESCRIPTION

[0026] The following is a detailed description of a quantitative cutting device for producing energy-saving fireproof boards provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. For some known technologies, those skilled in the art may also adopt other alternative methods to implement them; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0027] like Figure 1 - Figure 3 As shown, an embodiment of the utility model provides a quantitative cutting device for the production of energy-saving fireproof panels, including a material placing plate 4 and a bracket 2 arranged above the material placing plate 4, the top of the bracket 2 is fixedly connected to a hydraulic cylinder 3, the output end of the hydraulic cylinder 3 is fixedly connected to a cutting assembly 1 through the top of the bracket 2, the cutting assembly 1 includes a movable seat 11 and a cutting knife 12, the cutting knife 12 is fixedly connected to the middle position of the bottom of the movable seat 11, the bottom of the movable seat 11 is connected to a limiting plate 13 through a threaded rod 14, the middle position of the limiting plate 13 is provided with a knife groove 131, the blade of the cutting knife 12 passes through the knife groove 131 and extends to the bottom of the limiting plate 13, the bottom of the limiting plate 13 is connected to a pressure rod 15 through a spring 16, the pressure rod 15 is provided with two, and is separately arranged on both sides of the bottom of the knife groove 131, when not in working state, the initial horizontal height of the bottom of the pressure rod 15 is lower than the blade part of the cutting knife 12.

[0028] When cutting the fireproof board, the hydraulic cylinder 3 drives the movable seat 11 to descend, and the pressure rod 15 first contacts the top of the fireproof board on both sides of the cutting point, and cooperates with the top of the material placing plate 4 to continuously apply extrusion force under the action of the spring 16. While the cutting knife 12 cuts down, the elastic force of the spring 16 increases, so that the two sides of the cutting point of the fireproof board always remain flat during cutting, avoiding the deformation of the incision position caused by the cutting knife 12 extruding the fireproof board into the guide groove during cutting, thereby ensuring the quantitative cutting accuracy.

[0029] like Figure 1 As shown, a material placement groove 41 is provided on the top of the material placement plate 4 for placing the fireproof board. At the same time, a sunken guide groove perpendicular to the use direction of the material placement plate 4 is provided on the material placement plate 4 directly below the cutting knife 12, and an electric push rod for pushing the fireproof board is provided at one end of the material placement groove 41, and a quantitative cutting plate with an adjustable distance between the material placement groove 41 and the bracket 2 is provided at the other end to control the quantitative cutting length of the fireproof board (refer to Figure 1 ).

[0030] A material placement groove 41 is provided for placing the fireproof board, and at the same time, the left and right sides of the fireproof board are horizontally limited to avoid its deviation, thereby ensuring that the fireproof board is placed horizontally on the top of the material placement plate 4.

[0031] like Figure 2 As shown, the bracket 2 includes a mounting frame 21, and mounting grooves 22 symmetrically arranged on the two side walls of the mounting frame 21. The mounting frame 21 is a U-shaped frame structure, and the mounting groove 22 is socket-connected with a slider 5. The back side of the slider 5 is provided with a mounting plate 51, and the mounting plate 51 is fixedly connected to the side wall of the mounting frame 21 by a plurality of screws. The slider 5 passes through the mounting groove 22 and extends to the inside of the mounting frame 21.

[0032] When assembling the device, the mounting plate 51 is fixedly connected to the two sides of the mounting frame 21 by screws, so that the slider 5 can be installed and fixed. When disassembling, the slider 5 is removed first, so as to further remove the components inside the mounting frame 21.

[0033] like Figure 3 As shown, slide grooves 111 are symmetrically provided on both sides of the movable seat 11 , and the slide grooves 111 are slidably connected with the sliders 5 extending into the interior of the mounting frame 21 .

[0034] By providing a slide groove 111 and a sliding connection with the slider 5, it is ensured that the movable seat 11 always makes a linear motion in the vertical direction under the drive of the hydraulic cylinder 3, thereby ensuring the flatness of the cut end surface of the fireproof board. At the same time, the cutting force direction of the cutting knife 12 is the same as that of the knife body, which plays a certain protective role on the blade of the cutting knife 12.

[0035] like Figure 3 As shown, a mounting hole 112 is opened on the top of the movable seat 11, and there are four mounting holes 112. There are four threaded rods 14, which are vertically fixedly connected to four positions near the corners on the top of the limiting plate 13. The top of each threaded rod 14 passes through the four mounting holes 112 and is threadedly connected with a butterfly nut 18. There are four butterfly nuts 18.

[0036] When in use, the depth of the threaded rod 14 can be adjusted from bottom to top according to the thickness of the fireproof board to be cut, and the butterfly nut 18 can be used to thread and fix the height. When the thickness of the fireproof board is large, since the pressure rod 15 is blocked by the top of the fireproof board, the blade of the cutting knife 12 is deeper than the pressure rod 15, then the limit plate 13 needs to be adjusted upward so that the height of the pressure rod 15 is close to the bottom of the blade of the cutting knife 12, thereby reducing the depth of the blade of the cutting knife 12 and the bottom of the pressure rod 15 during cutting, thereby reducing the downward pressure of the spring 16 on the pressure rod 15 during cutting, and avoiding extrusion deformation of the surface of the fireproof board caused by excessive pressure. On the contrary, when the thickness of the fireproof board is small, the height of the limit plate 13 needs to be appropriately adjusted downward, thereby increasing the downward pressure of the spring 16 on the pressure rod 15 during cutting, and avoiding failure of the pressure rod 15 due to too low pressure on the fireproof board.

[0037] like Figure 3 As shown, a sliding rod 17 is fixedly connected to the top of the pressure rod 15, and there are multiple sliding rods 17. The limiting plate 13 is provided with sliding holes 132 on both sides of the knife groove 131. There are multiple sliding holes 132, which are slidably connected with the sliding rod 17. A through hole 113 is provided on the top of the movable seat 11. There are multiple through holes 113, which are slidably connected with the sliding rod 17.

[0038] The sliding hole 132 is used in conjunction with the sliding rod 17 to ensure that the pressure rod 15 can be made to descend in a straight line while the movable seat 11 descends during cutting, and can be used to accurately fit the positions on both sides of the cutting point, thereby avoiding the problem of low accuracy of the pressing point caused by the shaking caused by the spring 16 connecting the limit plate 13 and the pressure rod 15 alone. At the same time, a through hole 113 is opened at the top of the movable seat 11 to facilitate cutting of thicker fireproof boards. Due to the excessive proximity of the limit plate 13 to the bottom of the movable seat 11, the high point of the slide rod 17 at the top of the pressure rod 15 is against the bottom of the movable seat 11 during the actual cutting of the cutting knife 12 to the bottom of the guide groove, causing the movable seat 11 to be unable to continue to descend.

[0039] like Figure 2 As shown, the spring 16 is sleeved on the slide rod 17 , and two ends thereof are fixedly connected to the bottom of the limit plate 13 and the top of the pressure rod 15 respectively.

[0040] In summary, compared with the prior art, the present invention has the following beneficial effects: when the movable seat 11 descends, the pressure rod 15 first contacts the two sides of the cutting point of the fireproof board, and applies continuous downward pressure through the elastic force of the spring 16, thereby avoiding the deformation of the incision position caused by the blade of the cutting knife 12 squeezing the fireproof board toward the guide groove during cutting, thereby ensuring the quantitative cutting accuracy; by providing a detachable slider 5 for sliding limit of the movable seat 11, the cutting force direction of the cutting knife 12 is the same as that of the knife body, which has a certain protective effect on the blade of the cutting knife 12 and is convenient for disassembly and assembly; by changing the distance between it and the movable seat 11 through the adjustable limit plate 13, it is convenient for cutting fireproof boards of different thicknesses.

[0041] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
