Description

Technical Field

[0001] This utility model belongs to the technical field of PVC roll construction equipment, specifically a PVC roll laying flatness control device. Background Technology

[0002] PVC rolls are a type of polymer material made from polyvinyl chloride resin as the main raw material, with the addition of plasticizers, stabilizers, fillers and other additives, through processes such as mixing, plasticizing and calendering. They have many excellent properties such as waterproofing, anti-aging, high flexibility and environmental protection, and are widely used in construction, decoration and other fields.

[0003] A search revealed a waterproof membrane laying device with publication number CN205531075U. This device addresses the issue that during PVC membrane heat application, one person is needed to spread the membrane, another to heat it, another to lay it, and yet another to use a pressure roller to remove air bubbles. This results in high labor intensity for workers and a risk of burns. The proposed solution involves using a pressure roller and a heating torch. When laying the membrane, the torch is turned on to heat the membrane near the cold primer on the roof. The pressure roller is then placed on the surface of the membrane to be laid, leveled, and aligned. The device can then be moved using a handle. While it offers the advantages of single-person operation and simplicity, it still has shortcomings in practical use. Since the PVC membrane laying relies entirely on the pressure roller, uneven laying can easily occur if the roof surface is uneven or has bumps, making it difficult to control. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides a PVC roll material laying flatness control device, which has the advantage of improving laying flatness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PVC roll material laying flatness control device, comprising a vehicle body, an extension plate fixedly installed on the left side of the top of the vehicle body, limit rods movably sleeved on the front and rear sides of the left side of the bottom end of the extension plate, a rubber block fixedly installed at the bottom end of the limit rod, a round rod fixedly installed at the middle of the top end of the rubber block, a spring fixedly installed at the top end of the rubber block outside the round rod, the other end of the spring fixedly connected to the bottom end of the extension plate, the top end of the round rod penetrating the extension plate and extending to the top of the extension plate and fixedly installed with a fixing frame, the bottom end of the fixing frame movably connected to the top end of the extension plate, the bottom end of the fixing frame fixedly connected to the top end of the limit rod, a horizontal plate fixedly installed at the top right end of the fixing frame, a first motor fixedly installed on the left side of the middle of the top end of the extension plate, a first rotating shaft fixedly sleeved on the other end of the output shaft of the first motor, an elliptical block fixedly sleeved on the left side of the outer surface of the first rotating shaft, and the outer surface of the elliptical block movably connected to the bottom end of the horizontal plate.

[0006] As a preferred embodiment of this utility model, two hanging rods are fixedly installed on the front and rear sides of the left side of the bottom end of the extension plate, respectively, located on the right side of the limiting rod. The bottom ends of the two hanging rods are movably sleeved with pressure rollers.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 5As shown, this utility model provides a PVC roll material laying flatness control device, including a vehicle body 1. An extension plate 2 is fixedly installed on the left side of the top of the vehicle body 1. Limiting rods 3 are movably sleeved on the front and rear sides of the left side of the bottom of the extension plate 2. A rubber block 4 is fixedly installed at the bottom of the limiting rod 3. A round rod 5 is fixedly installed in the middle of the top of the rubber block 4. A spring 6 located outside the round rod 5 is fixedly installed at the top of the rubber block 4. The other end of the spring 6 is fixedly connected to the bottom of the extension plate 2. The top of the round rod 5 passes through the extension plate 2 and extends to the top of the extension plate 2, and a fixing frame 7 is fixedly installed thereon. The bottom of the fixing frame 7 is movably connected to the top of the extension plate 2. The bottom of the fixing frame 7 is fixedly connected to the top of the limiting rod 3. A horizontal plate 8 is fixedly installed at the top right end of the fixing frame 7. A first motor 9 is fixedly installed on the left side of the middle of the top of the extension plate 2. The first motor 9 outputs... The other end of the shaft is fixedly sleeved with a first rotating shaft 10. An elliptical block 11 is fixedly sleeved on the left side of the outer surface of the first rotating shaft 10. The outer surface of the elliptical block 11 is movably connected to the bottom end of the horizontal plate 8. When the first motor 9 is started, the first rotating shaft 10 will drive the elliptical block 11 to rotate. Since the outer surface of the elliptical block 11 is movably connected to the outer surface of the horizontal plate 8, as the elliptical block 11 rotates, the elliptical block 11 will generate a pushing force on the horizontal plate 8, pushing the horizontal plate 8 to move with the fixed frame 7. This causes the limiting rod 3 and the round rod 5, which are fixedly connected to the fixed frame 7, to move together with the rubber block 4 and compress the spring 6. Under the restoring action of the spring 6, when the elliptical block 11 no longer pushes the horizontal plate 8, the rubber block 4 will return to its original position. In this way, the PVC roll material can be patted by the rubber block 4, thereby improving the flatness of the PVC roll material.

[0022] Among them, two hanging rods 12 are fixedly installed on the front and rear sides of the left side of the bottom end of the extension plate 2, which are located on the right side of the limiting rod 3. There are two hanging rods 12, and the bottom ends of the two hanging rods 12 are movably sleeved with pressure rollers 13. Due to the presence of the hanging rods 12, the pressure rollers 13 will play a supporting and fixing role. The presence of the pressure rollers 13 will squeeze the PVC roll material during the laying process, thereby assisting the laying operation of the PVC roll material.

[0023] Among them, a fixing frame 14 is fixedly installed on the middle of the back of each of the two hanging rods 12. An L-shaped scraper 15 is movably sleeved on the front of the left end of the fixing frame 14. The top of the right end of the L-shaped scraper 15 is movably connected to the left end of the extension plate 2. The presence of the fixing frame 14 will limit the movement of the L-shaped scraper 15, thereby ensuring the stability of the movement of the L-shaped scraper 15. At the same time, when the elliptical block 11 pushes the rubber block 4 to the highest position, the bottom end of the rubber block 4 will be aligned with the right side of the top end of the L-shaped scraper 15.

[0024] The second motor 16 is fixedly installed at the left end of the top center of the extension plate 2, and the other end of the output shaft of the second motor 16 is fixedly sleeved with the second rotating shaft 17. When the second motor 16 is started, the second rotating shaft 17 will rotate, thereby providing a stable power for the movement of the L-shaped scraper 15 through the cooperation of the second motor 16 and the second rotating shaft 17.

[0025] In this design, a long rod 18 is fixedly sleeved on the left side of the outer surface of the second rotating shaft 17, and a short rod 19 is movably sleeved on the bottom end of the long rod 18. The outer surface of the short rod 19 is fixedly connected to the left end of the L-shaped scraper 15. When the second rotating shaft 17 rotates, it will rotate along with the long rod 18. Since the short rod 19 is movably sleeved inside the long rod 18 and fixedly connected to the outer surface of the L-shaped scraper 15, as the long rod 18 rotates, the long rod 18 will generate a thrust on the short rod 19, pushing the short rod 19 and the L-shaped scraper 15 to move.

[0026] Among them, roll material brackets 20 are fixedly installed on the left side of both the front and rear ends of the vehicle body 1, and heating torches 21 are fixedly installed on the left side of the bottom end of the vehicle body 1. The roll material brackets 20 are used to place PVC rolls, and the bottom end of the roll material brackets 20 is provided with reinforcing ribs to improve the stability of the PVC rolls. The heating torches 21 are used to heat the PVC rolls during the laying process.

[0027] A handle 22 is fixedly installed on the right side of the top of the vehicle body 1, and rollers 23 are movably installed on the left and right sides of the bottom of the vehicle body 1. The handle 22 makes it easier for the operator to pull the vehicle body 1, while the rollers 23 make it easier to move the vehicle body 1.

[0028] Working principle and usage process of this utility model:

[0029] During the PVC roll material laying process using pressure roller 13 and heating torch 21, the operator starts the first motor 9, causing the first rotating shaft 10 to drive the elliptical block 11 to rotate. This causes the elliptical block 11 to exert a pushing force on the horizontal plate 8, pushing the horizontal plate 8 through the fixed frame 7, round rod 5 and limiting rod 3, and moving the rubber block 4 to compress the spring 6. When the elliptical block 11 stops pushing the horizontal plate 8, the spring 6 will restore the rubber block 4 to its original position. This cycle is repeated, and the rubber block 4 can be used to pat the PVC roll material, thereby improving the flatness of the PVC roll material laying.

[0030] When the bottom of the rubber block 4 is covered with solidified protrusions such as adhesive, the operator starts the second motor 16 after the elliptical block 11 pushes the rubber block 4 to its highest position. This causes the second rotating shaft 17 to drive the long rod 18 to rotate, thereby generating a thrust on the outer surface of the short rod 19 from the inner surface of the long rod 18. This pushes the short rod 19, along with the L-shaped scraper 15, to move along the outer surface of the fixing frame 14. The L-shaped scraper 15 then scrapes and cleans the adhesive on the bottom of the rubber block 4, preventing solidified protrusions such as adhesive from adhering to the bottom of the rubber block 4 and affecting the quality of its patting of the PVC roll.
