[0002] During on-site construction, it is often necessary to make the skirting board into an arc shape to meet the site requirements. Currently, there are various styles of skirting board rolling machines on the market. Some of these large-scale automated rolling machines are highly efficient, but they are also expensive, have complex structures, require professional operators and a large workspace. For some small processing enterprises or individual businesses, the purchase and use costs are too high, and if the construction site space is small, they are even more inconvenient to carry. Utility Model Content

[0003] This utility model addresses the existing technical problems by providing a manual rolling machine.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A manual rolling machine includes a housing, an active component, a driven component, and a handle.

[0017] like Figures 1 to 3 As shown, this utility model discloses a manual rolling machine, including a housing 1, an active component, a driven component, and a handle 10. The housing 1 is made of Q235 iron plate after bending and spraying, which has sufficient stability and load-bearing capacity to ensure the overall stability. The active component includes an active shaft 2, an active wheel 3, and a connecting sleeve 4. One end of the active shaft 2 is rotatably mounted on the housing 1 through a bearing, and the other end of the active shaft 2 is equipped with a handle 10. The active wheel 3 is interference-fitted onto the active shaft 2, and the two ends of the active wheel 3 are equipped with connecting sleeves 4. There are three sets of driven components. There is a space between the middle driven component and the active component for the skirting board 11 to pass through. Each set of driven components includes a driven shaft 5, a driven wheel 6, and a connecting sleeve 7. The driven shaft 5 is mounted on the housing 1. The two ends of the driven wheel 6 are rotatably mounted on the driven shaft 5 through bearings. The two ends of the driven wheel 6 are equipped with connecting sleeves 7. The middle driven shaft 5 is connected to the active shaft 2.

[0018] The manual rounding machine also includes a lead screw 8 and a connecting plate 9. The connecting plate 9 is located inside the housing 1, which has a vertically arranged adjustment groove. The drive shaft 2 and the driven shaft 5 of the intermediate driven assembly pass through the adjustment groove and are connected to the connecting plate 9. The drive shaft 2 and the connecting plate 9 are rotatably connected. The connecting plate 9 is L-shaped. The lead screw 8 passes through the housing 1 and is connected to the connecting plate 9. By manually adjusting the lead screw 8, the connecting plate 9 can be moved up and down, thereby adjusting the height of the drive shaft 2 and the intermediate driven shaft 5, i.e., adjusting the height of the drive wheel 3 and the intermediate driven wheel 6, to accommodate the production of skirting boards 11 of different sizes, increasing the applicability of the manual rounding machine. After adjusting the drive wheel 3 and the driven wheel 6 of the intermediate driven assembly to the corresponding positions, the adjusting lead screw 8 is locked by the lock nut to reduce the wobbling of the drive wheel 3 and the driven wheel 6, further improving the bending accuracy of the skirting board 11.

[0019] The manual rolling machine also includes a second connecting plate 15, which is located on the front side of the housing 1. One end of the second connecting plate 15 is connected to the drive shaft 2, and a bearing is provided between the drive shaft 2 and the second connecting plate 15. The other end of the second connecting plate 15 is connected to the intermediate driven shaft 5. This further improves the stability of the connection between the drive wheel 3 and the intermediate driven wheel 6, and further improves the bending accuracy.

[0020] In this embodiment, the driving wheel 3 and the driven wheel 6 are made of nylon. Nylon has good wear resistance and self-lubricating properties, which can reduce frictional resistance and extend service life. At the same time, nylon is also lightweight, reducing the overall weight and making it easy to carry and operate. Furthermore, the driving wheel 3 and the driven wheel 6 are machined on a CNC lathe, which effectively ensures the machining quality and precision of the skirting board 11.

[0021] In this embodiment, the housing 1 has an upward-facing receiving cavity, and three driven components are disposed within the receiving cavity. The driven wheel 6 protrudes at least partially from the opening of the receiving cavity. The receiving cavity protects the driven components from interference from the external environment, ensures that the driven wheel 6 can rotate normally, and prevents collisions. Since the driven wheel 6 protrudes at least partially from the opening of the receiving cavity, it is easy to contact the skirting board 11 and bend it.

[0022] Furthermore, the inner plate of the receiving cavity is provided with a vertically arranged adjustment groove 12, and the outer plate of the receiving cavity is provided with a vertically arranged adjustment groove 13. One end of the driven shaft 5 passes through the adjustment groove 12 and is connected to the connecting plate 9, while the other end is mounted on the adjustment groove 13. The drive shaft 2 also passes through the adjustment groove 12 and is connected to the connecting plate 9. By adjusting the positions of the drive shaft 2 and the intermediate driven shaft 5, the positions of the drive wheel 3 and the intermediate driven wheel 6 can be adjusted to meet the bending requirements of different sizes of the skirting board 11, thus improving the flexibility and adaptability of the manual rolling machine.

[0023] In this embodiment, the handle 10 includes a support rod and a bakelite sleeve. The support rod is made of carbon steel, which has sufficient strength and load-bearing capacity to ensure operational stability. The bakelite sleeve is fitted onto the support rod, which increases grip comfort and reduces fatigue during operation.

[0024] Furthermore, the lugs 14 fixed on both sides of the housing 1 facilitate the handling and fixing of the manual rolling machine, improving its ease of use.

[0025] The operation process of this manual rounding machine is as follows: The operator places the kick line 11 between the driven wheel 6 and the driving wheel 3 of the middle driven component, and clamps the kick line 11 in cooperation with the driven components on both sides. Then, the operator manually turns the handle 10, which drives the driving shaft 2 and the driving wheel 3 to rotate. As the kick line 11 is continuously fed, there is friction between the kick line 11 and the driven wheel 6, which drives the driven wheel 6 to rotate around the driven shaft 5. Since there is a height difference between the driving wheel 3 and the driven wheels 6 on both sides, the kick line 11 is bent and rolled during its movement.

[0026] During the rolling process, the operator can adjust the lead screw 8 as needed. Through the connection between the lead screw 8 and the connecting plate 9, the height of the driving wheel 3 and the middle driven wheel 6 can be adjusted, that is, the distance between the driving wheel 3 and the driven wheels 6 on both sides in the height direction can be adjusted. This allows for bending and rolling of the skirting board 11 to different sizes, improving the applicability of the manual rolling machine and reducing operating costs. At the same time, since the driving wheel 3 and the driven wheel 6 are made of nylon, they have good wear resistance and self-lubricating properties, which can reduce frictional resistance during the rolling process and improve rolling efficiency.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
