Description

Technical Field

[0001] This utility model relates to the field of ground moisture-proof construction and laying technology, specifically to a polypropylene cloth laying device for ground moisture-proof construction. Background Technology

[0002] In the field of ground moisture-proof construction technology, it is usually necessary to lay polypropylene cloth on the ground and then coat it with cement to prevent the ground from becoming damp.

[0003] Currently, when laying polypropylene fabric, workers mainly unroll the polypropylene fabric from rolls and lay it on the ground. However, because polypropylene fabric is rolled up, it is relatively heavy and difficult to lay at the beginning. Furthermore, laying it by simply unrolling the polypropylene fabric naturally can easily result in many wrinkles on the laid polypropylene fabric, which increases the labor intensity of removing wrinkles from the polypropylene fabric later. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a polypropylene cloth laying device for ground moisture-proof construction, which can make the laying of polypropylene cloth more convenient and reduce the wrinkles generated during the laying process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a polypropylene cloth laying device for ground moisture-proof construction, comprising a frame, rollers at the bottom of the frame for moving the frame, a material rod for mounting polypropylene cloth rolls on the frame, a U-shaped groove on the frame for supporting the end of the material rod, multiple guide rods on both the front and rear sides of the material rod, polypropylene cloth pulled from the polypropylene cloth rolls passing through the guide rods in sequence for tensioning, and a flip-up pressure roller on the front side of the frame, which rolls the polypropylene cloth during the laying process to reduce wrinkles generated during the laying process.

[0006] The present invention is further configured such that: an inner connecting rod is provided on the inner side of the frame, one end of the inner connecting rod is rotatably connected to the inner side of the frame, and the other end is provided with a bracket. A connecting frame is provided below the bracket. The two ends of the pressing roller are rotatably connected to the two sides of the connecting frame. A coupling rod is provided at one end of the inner connecting rod located on the connecting bracket. An arc-shaped guide opening corresponding to the coupling rod is provided on the frame. The coupling rod extends to the arc-shaped guide opening. When the coupling rod moves to the bottom end of the arc-shaped guide opening, the pressing roller can contact the pulled polypropylene cloth. When the coupling rod moves to the top end of the arc-shaped guide opening, the pressing roller moves away from the pulled polypropylene cloth.

[0007] The present invention is further configured such that: the support has a threaded hole at its center, and guide holes are provided on both sides of the threaded hole; the connecting frame has a screw at its center that can form a threaded engagement with the threaded hole; and guide rods are provided on both sides of the connecting frame that can form a sliding engagement with the guide holes. The screw, by rotating, adjusts the distance between the pressure roller and the polypropylene cloth when the polypropylene cloth is laid.

[0008] The present invention is further configured such that: an outer connecting rod is provided on the outer side of the frame, one end of the outer connecting rod is rotatably connected to the outer side of the frame, and the other end is provided with a rotatable anti-moving wheel; a torsion spring is provided at the connection between the outer connecting rod and the frame; and the anti-moving wheel is used to abut against the coupling rod to improve the stability of the pressing roller when pressing the cloth.

[0009] The present invention is further configured such that: the outer periphery of the coupling rod is provided with a positioning groove corresponding to the anti-moving wheel, the positioning groove being used to ensure the stability of the anti-moving wheel abutting against the coupling rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. Because a U-shaped slot is set on the frame, the U-shaped slot is used to support the end of the material rod to position and support the polypropylene cloth roll. As a result, the worker does not need to overcome the weight of the polypropylene cloth roll when laying it, which makes the laying of polypropylene cloth more convenient.

[0012] 2. By setting multiple guide rods on both the front and rear sides of the frame, the polypropylene fabric pulled from the polypropylene fabric roll passes through the guide rods in sequence to tighten it, reducing the wrinkles generated when the pulled polypropylene fabric is laid on the ground.

[0013] 3. By providing a flip-up pressure roller on the front side of the frame, the flip-up design of the pressure roller increases the distance between the pressure roller and the ground when the polypropylene fabric is pulled out and placed under the pressure roller, thus facilitating the preparation before use. After the polypropylene fabric is pulled out and placed under the pressure roller, the pressure roller is flipped back to its original position, so that the pressure roller can roll the polypropylene fabric during the laying process to reduce wrinkles generated during the laying process.

[0020] like Figures 1 to 4 As shown, this utility model discloses a polypropylene fabric laying device for ground moisture-proof construction, including a frame 1. The bottom of the frame 1 is equipped with rollers 2 for moving the frame 1. The frame 1 is equipped with a material rod 3 for mounting polypropylene fabric rolls. The frame 1 is also equipped with a U-shaped groove 4 for supporting the end of the material rod 3, thus positioning and supporting the polypropylene fabric roll, making the laying of the polypropylene fabric more convenient. When the polypropylene fabric roll on the material rod 3 is pulled outwards, the material rod 3 can rotate within the U-shaped groove 4, causing the polypropylene fabric roll mounted on the material rod 3 to rotate, thereby facilitating the outward pulling of the polypropylene fabric. Multiple guide cloths are provided on both the front and rear sides of the material rod 3 on the frame 1. Rod 5 is used to guide the polypropylene fabric from the roll through the guide rod 5 for tensioning, reducing wrinkles when the polypropylene fabric is laid on the ground. The front of the frame 1 is equipped with a flip-up pressure roller 6. The flip-up design of the pressure roller 6 allows the distance between the pressure roller 6 and the ground to be increased when the polypropylene fabric is pulled under the pressure roller 6, which facilitates the preparation before use. After the polypropylene fabric is pulled under the pressure roller 6, the pressure roller 6 is flipped back to its original position, so that the pressure roller 6 can roll the polypropylene fabric during the laying process to reduce wrinkles.

[0021] In this embodiment, the structure for the fabric pressing roller 6 to flip is as follows: an inner connecting rod 7 is provided on the inner side of the frame 1. One end of the inner connecting rod 7 is rotatably connected to the inner side of the frame 1 via a pin, and the other end is provided with a bracket 8. A connecting frame 9 is provided below the bracket 8. The two ends of the fabric pressing roller 6 are rotatably connected to both sides of the connecting frame 9. A coupling rod 10 is provided at one end of the inner connecting rod 7 located on the connecting bracket 8. An arc-shaped guide opening 11 corresponding to the coupling rod 10 is provided on the frame 1. The coupling rod 10 extends to the arc-shaped guide opening 11. By rotating the inner connecting rod 7, the connecting frame 9 can be rotated. The movement of the inner connecting rod 7 causes the pressure roller 6 connected to the connecting frame 9 to rotate. During the rotation of the inner connecting rod 7, the coupling rod 10 can move along the path of the arc-shaped guide opening 11, thereby guiding the rotation of the inner connecting rod 7 and ensuring the stability of the pressure roller 6 when it rotates. When the coupling rod 10 moves to the bottom of the arc-shaped guide opening 11 through the rotation of the inner connecting rod 7, the pressure roller 6 can contact the pulled polypropylene cloth. When the coupling rod 10 moves to the top of the arc-shaped guide opening 11, the pressure roller 6 moves away from the pulled polypropylene cloth.

[0022] In this embodiment, a threaded hole is provided in the center of the bracket 8, and guide holes are provided on both sides of the threaded hole. A lead screw 12 is provided in the center of the connecting frame 9, which can form a threaded engagement with the threaded hole. Guide rods 13 are provided on both sides of the connecting frame 9, which can form a sliding engagement with the guide holes. The lead screw 12 rotates, and the connecting frame 9 is raised and lowered under the limiting action of the guide rods 13 and the guide holes. Thus, when laying polypropylene cloth, the distance between the pressure roller 6 and the polypropylene cloth can be adjusted to adapt to polypropylene cloth of different thicknesses and expand the adaptation range.

[0023] In this embodiment, an outer connecting rod 14 is provided on the outer side of the frame 1. By setting the outer connecting rod 14 and the inner connecting rod 7 on the outer and inner sides of the frame 1 respectively, the space utilization of the frame 1 can be improved, making the overall design more compact, reducing the footprint, and making the use more flexible. One end of the outer connecting rod 14 is rotatably connected to the outer side of the frame 1, and the other end is provided with a rotatable anti-moving wheel 15. A torsion spring 16 is provided at the connection between the outer connecting rod 14 and the frame 1. Through the resistance applied by the torsion spring 16, the anti-moving wheel 15 can stably abut against the coupling rod 10 during the laying of polypropylene cloth to limit the coupling rod 10, thereby preventing the pressure roller 6 from moving during the rolling of the polypropylene cloth, thus improving the stability of the pressure roller 6 when pressing the cloth.

[0024] In this embodiment, a positioning groove 101 corresponding to the anti-moving wheel 15 is provided on the outer periphery of the coupling rod 10. When the anti-moving wheel 15 is coupled to the positioning groove 101, the positioning groove 101 can limit the anti-moving wheel 15 axially, thereby ensuring the stability of the anti-moving wheel 15 abutting against the coupling rod 10.

[0025] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
