Description

Technical Field

[0001] The invention relates to the technical field of sawing of calcium silicate composite boards, and in particular to sawing equipment for a production line of calcium silicate composite boards. Background Art

[0002] Calcium silicate composite board is produced by the reaction of siliceous materials (such as quartz sand) and calcium materials (such as quicklime) under high temperature and high pressure. Calcium silicate has good heat resistance, water resistance and chemical stability. Especially in some industrial buildings in high temperature environments, the heat resistance of calcium silicate can ensure that the structure of the board is stable under long-term heating and will not deform or decompose. In order to facilitate the size adaptation requirements of calcium silicate composite boards and facilitate transportation and handling, it is often necessary to use a circular saw blade sawing machine to saw them.

[0003] When traditional sawing equipment is sawing calcium silicate composite boards, it not only requires manual assistance, but also requires the outer wall of the calcium silicate composite board away from the incision to fit with the reference block. Since the position of the saw blade is fixed, when obtaining calcium silicate composite boards of different widths, manual participation is required to adjust the distance between the reference block and the saw blade, which not only increases the workload of the personnel, but also manual adjustment is prone to errors, resulting in poor sawing effects. In this regard, the present application designs a sawing equipment for a calcium silicate composite board production line. Summary of the invention

During the sawing process, multiple sliding columns are used to reduce the side sliding resistance of the calcium silicate composite board when it is pushed by the operator for sawing, so that the calcium silicate composite board can slide more smoothly on the top of the sawing table, thereby allowing the sawing work to be carried out continuously and avoiding the problem of uneven incision caused by pauses.

[0041] An exhaust fan 801 is fixedly connected to the inside of the exhaust duct 701, and a transmission disk 802 is rotatably connected to the outer wall of the exhaust duct 701.

A rubber wheel 803 is rotatably connected to the outer wall of the dust hood 702. A transmission wheel 804 is rotatably connected to the outer wall of the dust hood 702 and located directly above the rubber wheel 803. The transmission wheel 804 and the rubber wheel 803 are frictionally transmitted.

[0042] In combination with the above preferred embodiments, the working principle of the present invention is as follows:

[0043] When working:

[0044] When sawing calcium silicate composite panels of different widths, it is necessary to pre-adjust the distance between the reference block 405 and the circular saw blade component 2. The operator starts the motor 41 through the button on the panel, so that the output shaft end of the motor 41 rotates with the screw rod 401. Since the fixed block 402 is rotatably connected to the screw rod 401, and the fixed block 402 is slidably matched with the ruler 403 through the rectangular block 404, when the screw rod 401 rotates, the fixed block 402 can move with the reference block 405 on the top of the sawing table 1, and by controlling the forward and reverse rotation of the motor 41, the purpose of changing the position of the reference block 405 is achieved, making it more convenient to adjust the distance between the reference block 405 and the incision of the circular saw blade component 2. At the same time, a plurality of marking boxes 601 are arranged at intervals on the top of the bracket 3, so that the operator can insert the insert block 602 into the marking box 601 at the corresponding position in advance, so that the spacing adjustment is more accurate. Compared with the traditional manual adjustment, the automation level is higher and the time spent on adjustment is shortened.

[0045] Then, the calcium silicate composite board is placed on the top of the sawing table 1, so that the side of the calcium silicate composite board away from the circular saw blade component 2 is aligned with the reference block 405. By setting a plurality of sliding columns 406, the calcium silicate composite board can reduce the side sliding resistance when being pushed by the operator for sawing, so that the calcium silicate composite board can slide more smoothly on the top of the sawing table 1, so that the sawing work can be carried out continuously and the problem of uneven incision caused by pauses can be avoided. At the same time, according to the thickness of the calcium silicate composite board, the first pressure wheel 504 can cooperate with the adjustment block 503 to slide up and down inside the upper support plate 501. In the initial state, when the first pressure wheel 504 is pushed by the thicker calcium silicate composite board, it will rise in height, otherwise it will fall in height. In addition, when the equipment is stopped, the first pressure wheel 504 will be reset under the action of the weight of the adjustment block 503 itself, which is convenient for the next use. By allowing the first pressure wheel 504 to always roll on the top of the calcium silicate composite board, it can be ensured that the calcium silicate composite board always fits the top of the sawing table 1, avoiding bouncing during the sawing process. At the same time, it can replace the method of manually applying downward pressure, thereby reducing the workload of the operator.

[0046] During the sawing of the calcium silicate composite board, due to the special manufacturing process of the calcium silicate composite board, the calcium silicate composite board has a relatively hard texture. During the contact with the high-speed rotating circular saw blade component 2, a large amount of dust will be generated, and the dust will also be mixed with some fine particulate impurities, which will easily pollute the working environment. At the same time, working in a dusty environment for a long time is not good for the health of the operator. By setting the exhaust duct 701, the dust collection cover 702 and the telescopic cover 703, a closed area can be formed above the circular saw blade component 2. When the calcium silicate composite board is pushed, the end away from the operator applying the thrust will first contact the second pressure wheel 75. In the initial state, the second pressure wheel 75 maintains a relatively low height. When the calcium silicate composite board exceeding the relatively low height passes, it will exert an upward thrust on the second pressure wheel 75. Since the support block 704 is fixedly connected to the dust hood 702, when the second pressure wheel 75 moves upward, the dust hood 702 will be lifted up synchronously, so that the exhaust pipe 701 slides upward on the inner wall of the bracket 3, thereby achieving the purpose of the dust hood 702 adapting to calcium silicate composite boards of different thicknesses. At the same time, the telescopic cover 703 can be adaptively extended and retracted according to the thickness of the calcium silicate composite board after contacting it under its own telescopic characteristics, ensuring that the bottom of the telescopic cover 703 always fits the surface of the calcium silicate composite board. During this period, the second pressure wheel 75 will also lift the column 705 and cooperate with the support block 704 to stretch the support spring 706. When the calcium silicate composite board is completely located below the second pressure wheel 75, the column 705 and the second pressure wheel 75 are reset under the rebound action of the support spring 706. By symmetrically arranging two second pressure wheels 75 in combination with a plurality of first pressure wheels 504, the calcium silicate composite board can be firmly fixed to the surface of the sawing table 1, thereby improving stability during sawing. At the same time, the dust collecting hood 702 and the telescopic hood 703 are always located above the circular saw blade component 2 and the calcium silicate composite board, which helps to collect and process the dust generated by sawing, reduces the probability of dust overflow, and avoids pollution of the working environment.

[0047] The rubber wheel 803 is located on the outer wall of the dust hood 702, so that the rubber wheel 803 will move synchronously with the dust hood 702, and thus adapt to calcium silicate composite plates of different thicknesses. When the surface of the calcium silicate composite plate contacts the rubber wheel 803, the rubber wheel 803 rotates under the action of a large friction force. At the same time, the rubber wheel 803 rotates the transmission wheel 804 and the transmission plate 802 through the friction force. Since the diameter of the rubber wheel 803 is larger than the diameter of the transmission wheel 804, the transmission wheel 804 can rotate several times when the rubber wheel 803 rotates one circle, thereby driving the exhaust fan 801 to rotate quickly (here the transmission wheel 804 can be replaced by a friction wheel or a bevel gear to improve the flexibility of use). The exhaust fan 801 rotates quickly inside the exhaust pipe 701, thereby generating upward wind force. Combined with the air intake in the bottom area of ​​the dust hood 702, the air flow rate can be accelerated, thereby achieving the purpose of exhaust, which is conducive to the discharge of dust after filtration.

[0048] When the dust and particulate impurities generated by sawing will diffuse to the two ends of the circular saw blade component 2, the dust collecting hood 702 can be used to prevent overflow. By arranging an arc-shaped dust collecting plate 903 inside the dust collecting hood 702, and opening dust collecting channels 904 on both sides of the arc-shaped dust collecting plate 903 in the diffusion direction, the diffused dust and particulate impurities can be guided, so that the diffused dust and particulate impurities enter the interior of the filter element 902 through the dust collecting channels 904 on both sides. Since the bottom of the rotating wheel 905 is at a lower height from the surface of the sawing table 1 than the bottom of the telescopic cover 703 in the initial state, when the top of the calcium silicate composite board just contacts the rotating wheel 905, an upward pushing force is exerted on the rotating wheel 905, so that the rotating wheel 905 slides upward on the side wall of the dust collecting cover 702, and pushes the lifting rod 907 and the arc-shaped ash collecting plate 903 upward through the two-stage connecting rod 906, so that the arc-shaped ash collecting plate 903 can be located above the recovery hole 908 after the height is raised, avoiding The arc-shaped ash collecting plate 903 is free from leakage after collecting particulate matter impurities in the concave part at the top. At the same time, when the recovery hole 908 is located below the arc-shaped ash collecting plate 903, the air intake in the dust hood 702 area can be increased, thereby cooperating with the exhaust fan 801 to improve the exhaust effect. When the lifting rod 907 lifts the two opening and closing plates 91 upward, the two opening and closing plates 91 are turned toward one side of the center line at the same time, and the torsion spring is squeezed at the same time, which makes the exhaust pipe 701 and the internal channel of the dust hood 702 open, so that the exhaust effect is improved. As the lifting rod 907 stops lifting, the two opening and closing plates 91 are reset under the rebound effect of the torsion spring, which is convenient for the next use. The two opening and closing plates 91 are used to block the connection channel between the dust hood 702 and the exhaust pipe 701 in the initial state, so that the exhaust pipe 701 and the dust hood 702 can be kept separated, so as to avoid the contamination of the exhaust pipe 701 before the exhaust starts, thereby reducing the probability of the exhaust pipe 701 being blocked.

[0049] Since both ends of the two-stage connecting rod 906 are hinged with the lifting rod 907 and the rotating wheel 905, and the arc-shaped dust collecting plate 903 is fixedly connected with the lifting rod 907 and slides inside the dust collecting cover 702, the rotating wheel 905 rolls on the surface of the calcium silicate composite plate under the action of friction. When the hinge between the two-stage connecting rod 906 and the rotating wheel 905 rotates to the highest point with the rotating wheel 905, the two-stage connecting rod 906 will push the lifting rod 907 and the arc-shaped dust collecting plate 903 to slide inside the dust collecting cover 702. The ash plate 903 moves upward, and makes the arc-shaped ash collecting plate 903 contact with the bottom of the filter element 902, and squeezes the air cushion 901 at the same time. When the two-stage connecting rod 906 rotates to the lowest point following the rotating wheel 905, the arc-shaped ash collecting plate 903 follows the lifting rod 907 to descend in height. The above process is repeated, so that the arc-shaped ash collecting plate 903 vibrates due to the up and down displacement. With the special shape of the arc-shaped ash collecting plate 903, the filtered element 902 is 02 The intercepted particulate impurities can fall from both sides to the lowest point on the surface of the curved ash collecting plate 903, ensuring that there is enough space on the surface of the curved ash collecting plate 903 to store the particulate impurities. At the same time, the curved ash collecting plate 903 repeatedly pushes up the filter element 902. Under the rebound action of the air cushion 901, the filter element 902 also produces a vibration effect, which can avoid the problem of poor filtering effect caused by dust blockage. After the rotary wheel 905 is separated from the calcium silicate composite plate, under the action of gravity, the rotary wheel 905 is reset on the side wall of the dust collecting hood 702, which is convenient for next use. At the same time, when the curved ash collecting plate 903 drops to a height below the recovery hole 908, the operator can regularly connect the vacuum cleaner pipe to the recovery hole 908 to uniformly recycle and process the dust and particulate impurities collected on the surface of the curved ash collecting plate 903, keep the surface of the curved ash collecting plate 903 clean, and do not need to be frequently disassembled and cleaned, thereby improving the convenience of equipment use.
