A knob is fixedly connected to the side end of the bidirectional threaded rod, and two sets of threaded sleeves are threadedly connected to the outer end of the bidirectional threaded rod. A movable plate is fixedly connected to the top end of each set of threaded sleeves. A motor is fixedly installed on the side end of one of the movable plates, and a limit plate is installed on the output end of the motor. The same limit plate is rotatably disposed on the side end of the other movable plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes a clamping mechanism to position a take-up drum containing a dustproof cloth between two sets of limiting plates. Rotating a knob drives a bidirectional threaded rod, causing two sets of threaded sleeves to bring two sets of moving plates closer together. This moves the limiting plates towards the insertion plates at both ends of the take-up drum until the insertion plates are within the two limiting slots. At this point, the two sets of moving plates clamp and fix the take-up drum. Then, one of the screw holes on the side of the knob aligns with the screw rod. Rotating the knob moves the screw rod down to the screw hole. Continued rotation causes the screw rod to connect with the screw hole, thus fixing the knob and, consequently, the positions of the two sets of moving plates, achieving the installation of the take-up drum. The motor is then started... The limit plate rotates, which in turn drives the take-up drum to rotate, automatically unwinding the dustproof cloth. Then, the construction worker can move the take-up box by pulling the handle and using the moving wheels. This allows the dustproof cloth to be automatically unwound during the movement of the take-up box, eliminating the need for manual dragging of the dustproof cloth. This facilitates the laying of the dustproof cloth and the construction site. After the dustproof cloth is unwound, the cutting mechanism pushes the push plate to move the cutting blade. The cutting blade cuts the dustproof cloth after passing through it. The cutting blade moves horizontally along the moving groove, and the slider moves within the groove to limit the cutting blade, thus facilitating length cutting after the dustproof cloth is unwound, improving the efficiency of dustproof cloth laying.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4As shown, this utility model provides a technical solution: a green construction dustproof device, including a winding box 1, a handle 101 fixedly connected to the side end of the winding box 1, two sets of moving wheels 102 installed at the bottom of the winding box 1, two sets of support legs 103 fixedly connected to the bottom of the winding box 1, the support legs 103 are used to support the ground when the winding box 1 is placed normally, a box door 104 is installed on the side end of the winding box 1, an opening 105 is opened at the side end of the box door 104, a horizontal groove 106 is opened at the bottom of the inside of the winding box 1, a clamping mechanism 2 is provided inside the horizontal groove 106, a winding drum 301 is provided between the inner sides of the clamping mechanism 2, a dustproof cloth 3 is wound at the outer end of the winding drum 301, a mounting frame 5 is fixedly connected to the side end of the box door 104 at the top of the opening 105, a moving groove 501 is opened at the top of the mounting frame 5, and a section from the top of the mounting frame 5 to the inside of the moving groove 501 is provided for... The cutting mechanism 6 and clamping mechanism 2 of the dustproof cloth 3 facilitate the clamping and fixing of the take-up drum 301, enabling the installation of the take-up drum 301. At this time, by passing the head end of the dustproof cloth 3 through the opening 105 and then closing the box door 104, the head end of the dustproof cloth 3 is placed on the ground. The head end of the dustproof cloth 3 is fixed to the ground by using ground nails or bricks or other heavy objects. The clamping mechanism 2 has an unwinding function. The construction personnel can move the take-up box 1 by pulling the handle 101 and cooperating with the moving wheel 102. At this time, the dustproof cloth 3 can be automatically unwound during the movement of the take-up box 1, without the need for manual dragging of the dustproof cloth 3 to unfold it, which is convenient for laying the dustproof cloth 3 and the construction site. Then, after the dustproof cloth 3 is unfolded, the cutting mechanism 6 facilitates the length cutting of the dustproof cloth 3 after unfolding, which improves the efficiency of laying the dustproof cloth 3.

[0021] As one implementation method in this embodiment, such as Figure 2 and Figure 3As shown, the clamping mechanism 2 includes a bidirectional threaded rod 201, which is rotatably disposed between the outer end of the winding box 1 and the inner end of the transverse groove 106. A knob 207 is fixedly connected to the side end of the bidirectional threaded rod 201, and several screw holes 208 are opened on the side end of the knob 207. Two sets of screw sleeves 202 are threadedly connected to the outer end of the bidirectional threaded rod 201. A movable plate 203 is fixedly connected to the top of each set of screw sleeves 202. A motor 205 is fixedly installed on the side end of one of the movable plates 203. The movable plate 203 has a built-in battery (not shown) and is electrically connected to the motor 205. The battery is removable and replaceable, and can also be charged for use to drive the motor 205. The switch (not shown) of the motor 205 is located on the surface of the winding box 1 and is electrically connected to the battery and the motor 205 for controlling the switching of the motor 205. A limiting plate 204 is installed at the output end of the machine 205. The side end of another movable plate 203 is rotatably equipped with the same limiting plate 204. Each limiting plate 204 has a limiting groove 206 on its side end. The left and right sides of the take-up drum 301 are fixedly connected with insert plates 302. Each insert plate 302 is adapted to each limiting groove 206. In practice, by placing the take-up drum 301 with the dustproof cloth 3 wound on between the two sets of limiting plates 204, the double-sided threaded rod 201 can be rotated by turning the knob 207. The two sets of threaded sleeves 202 drive the two sets of movable plates 203 to move closer to each other, so that the two sets of limiting plates 204 move towards the insert plates 302 at the left and right ends of the take-up drum 301 until the insert plates 302 at both ends are located in the two limiting grooves 206. At this time, it is convenient for the two sets of movable plates 203 to clamp and fix the take-up drum 301.

[0022] Furthermore, a side plate 4 is fixedly connected to the outer side of the winding box 1. A knob 401 is located at the top of the side plate 4, and a screw 402 is fixedly connected to the bottom of the knob 401. The screw 402 is threadedly connected to the top of the side plate 4 and into one of the screw holes 208. In practice, when the two sets of moving plates 203 clamp and fix the winding drum 301, one of the screw holes 208 on the side of the knob 207 is aligned with the position of the screw 402. By rotating the knob 401, the screw 402 is moved downwards to the position of the screw hole 208. Continued rotation causes the screw 402 to be threadedly connected to the screw hole 208, thereby fixing the knob 207 and thus fixing the positions of the two sets of moving plates 203, achieving the installation of the winding drum 301. The dustproof cloth 3 is inserted through the opening 105, and then the box door 104 is closed, so that the head end of the dustproof cloth 3 is on the ground. The head end of the dustproof cloth 3 is fixed to the ground by ground nails or bricks. Then, the motor 205 is started to drive the limiting plate 204 to rotate. At this time, the limiting plate 204 can drive the winding drum 301 to rotate, and the winding drum 301 can automatically unwind the dustproof cloth 3. Then, the construction personnel can move the winding box 1 by pulling the handle 101 and using the moving wheels 102. At this time, the dustproof cloth 3 can be automatically unwound during the movement of the winding box 1, without the need for manual dragging of the dustproof cloth 3 to unfold it, which is convenient for laying the dustproof cloth 3 and the construction site.

[0023] As one implementation method in this embodiment, such as Figure 1 and Figure 4 As shown, the cutting mechanism 6 includes a push plate 601, with a cutting blade 602 fixedly connected to the bottom end of the push plate 601. A slider 603 is fixedly connected to the side end of the cutting blade 602. A sliding groove 502 is provided inside the moving groove 501, and the slider 603 is slidably connected in the sliding groove 502. Magnets 604 that attract each other are respectively installed on the side end of the mounting frame 5 and the side end of the push plate 601. In practice, when the dustproof cloth 3 is unfolded, the cutting blade is moved by pushing the push plate 601. After passing through the dustproof cloth 3, the cutting blade 602 can... The cloth is cut and slit. The cutting scissors 602 move horizontally along the moving groove 501. The slider 603 moves within the groove 502 to limit the cutting scissors 602, which facilitates length cutting after the dustproof cloth 3 is unfolded, thus improving the efficiency of laying the dustproof cloth 3. Subsequently, by pushing the push plate 601 to align the magnet 604 with the magnet 604 on the side of the mounting frame 5, the two magnets 604 attract each other, which can position the push plate 601 at the far side of the mounting frame 5, so that the push plate 601 and the cutting scissors 602 will not move arbitrarily.

[0024] Working principle: By positioning the take-up drum 301 with the dustproof cloth 3 wound up between the two sets of limiting plates 204, rotating the knob 207 drives the bidirectional threaded rod 201 to rotate. This, through the two sets of threaded sleeves 202, causes the two sets of moving plates 203 to move closer together, causing the two sets of limiting plates 204 to move towards the insertion plates 302 at both ends of the take-up drum 301 until the insertion plates 302 are located within the two limiting grooves 206. At this point, the two sets of moving plates 203 clamp and fix the take-up drum 301. Then, one of the screw holes 208 on the side of the knob 207 is aligned with the screw... The position of rod 402 is determined by rotating knob 401, which moves screw 402 down to screw hole 208. Continuing to rotate screw 402 connects it to screw hole 208, thus fixing knob 207. This, in turn, fixes the positions of the two sets of moving plates 203, enabling the installation of winding drum 301. At this point, the dustproof cloth 3 is passed through opening 105, and then the door 104 is closed, placing the dustproof cloth 3 on the ground. Using ground nails or bricks, the dustproof cloth 3 is then fixed to the ground. By starting the motor 205, the limiting plate 204 is driven to rotate. The limiting plate 204 then drives the winding drum 301 to rotate, automatically unwinding the dustproof cloth 3. Next, the construction worker can move the winding box 1 by pulling the handle 101 and using the moving wheels 102. This allows for automatic unwinding of the dustproof cloth 3 during the movement of the winding box 1, eliminating the need for manual dragging. This facilitates the laying of the dustproof cloth 3 and the construction site. After the dustproof cloth 3 is unwound, pushing the push plate 601 causes it to be cut to... The cutting scissors 602 can cut the dustproof cloth 3 after it passes through the moving groove 501. The cutting scissors 602 moves horizontally along the moving groove 501, and the slider 603 moves in the groove 502 to limit the cutting scissors 602, so as to facilitate length cutting after the dustproof cloth 3 is unfolded, thus improving the efficiency of laying the dustproof cloth 3. Subsequently, by pushing the push plate 601 to align the magnet 604 with the magnet 604 on the side of the mounting frame 5, the two magnets 604 attract each other, so that the push plate 601 can be located at the sidemost end of the mounting frame 5, and the push plate 601 and the cutting scissors 602 will not move around randomly.

[0025] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
