[0002] Ventilation ducts are metal or composite pipes commonly used in ventilation and air conditioning projects in industrial and civil buildings to allow air circulation and reduce the concentration of harmful gases.

[0003] Three-roll rolling machines typically consist of one upper roller and two lower rollers. The diameter of the rolled tube is controlled by adjusting the distance between the upper and lower rollers. During operation, the metal sheet is placed between the upper and lower rollers, and the sheet is gradually bent and rolled into a circle by the rotation and pressure of the rollers. Existing rolling machines require manual handling of the material to work with the machine. If the fingers are too close, there is a risk of accidental entanglement, which reduces the safety of operating the rolling machine.

[0004] Therefore, the design of the rolling machine needs to be modified to effectively prevent the safety accident that may occur when the user holds the material and works with the machine, as the fingers may get too close and get caught. Utility Model Content

[0022] 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.

[0023] like Figures 1 to 4 As shown, the present invention provides a rolling machine for processing ventilation ducts, comprising:

[0024] Rolling machine body 1;

[0025] Fixed blocks 2 are fixedly connected to the left and right sides of the front end of the rolling machine body 1. Balance bars 3 are horizontally fixedly connected to the top and bottom of the inner side of the fixed blocks 2. A placement mechanism 4 is slidably sleeved on the surface of the balance bar 3.

[0026] The placement mechanism 4 includes a slider 41, an L-shaped contact plate 42, a handle 43, a rod 44, and a fixing box 45. The slider 41 is slidably sleeved on the surface of the balance bar 3. The top and bottom of the front end of the slider 41 are fixedly connected to the L-shaped contact plate 42. The top of the L-shaped contact plate 42 is fixedly connected to the handle 43. The inner side of the L-shaped contact plate 42 is movably connected to the rod 44 through a pivot. The right side of the slider 41 and the inner side of the balance bar 3 is fixedly connected to the fixing box 45. The front end and back end of the fixing box 45 are movably connected to the positioning mechanism 5.

[0027] refer to Figure 4The positioning mechanism 5 includes a pull rod 51, a triangular plate 52, a vertical rod 53, an L-shaped clamping plate 54, a Z-shaped plate 55, a fixing plate 56, and an insert rod 57. The front and back ends of the fixing box 45 are movably connected to the pull rod 51. The back end of the pull rod 51 extends through the interior of the fixing box 45 and is fixedly connected to the triangular plate 52. The bottom of the inner wall of the fixing box 45 is fixedly connected to the vertical rod 53. The top of the vertical rod 53 is fixedly connected to the top of the inner wall of the fixing box 45. The top and bottom of the surface of the vertical rod 53 are slidably fitted with the L-shaped clamping plate 54. The right side of the L-shaped clamping plate 54 extends through the right side of the fixing box 45 and is clamped to one side of the balance bar 3. The front and back ends of the L-shaped clamping plate 54 and are located inside the fixing box 45 are fixedly connected to the Z-shaped plate 55. The end of the Z-shaped plate 55 away from the L-shaped clamping plate 54 is fixedly connected to the fixing plate 56. The left side of the fixing plate 56 is fixedly connected to the insert rod 57. The left side of the insert rod 57 is slidably connected to the right side of the triangular plate 52.

[0028] As a technical optimization of this utility model, the positioning mechanism 5 can pull the pull rod 51 to move and drive the triangular plate 52 to follow. The movement of the triangular plate 52 forces the insertion rod 57 to move upward. The upward movement of the insertion rod 57 drives the fixing plate 56 and the Z-shaped plate 55 to move synchronously. The movement of the Z-shaped plate 55 drives the L-shaped clamping plate 54 to move in coordination and to insert and fix the balance bar 3.

[0029] refer to Figure 4 The top and bottom of the triangular plate 52 are provided with guide grooves 6, which are used in conjunction with the insertion rod 57.

[0030] As a technical optimization of this utility model, the guide groove 6 can assist the insertion rod 57 in its work and also serve as a limit, preventing the insertion rod 57 from detaching during movement.

[0031] refer to Figure 4 A return spring 7 is fixedly sleeved on the surface of the vertical rod 53 and inside the L-shaped plate 54. The top and bottom of the return spring 7 are fixedly connected to one side of the L-shaped plate 54, respectively.

[0032] As a technical optimization of this utility model, the reset spring 7 can assist the L-shaped clamping plate 54 in its work and also serve as a reset buffer, thus preventing the L-shaped clamping plate 54 from failing to reset after movement, which would cause the machine to stop working continuously.

[0033] refer to Figure 4 The top and bottom of the Z-shaped plate 55 are fixedly connected with reinforcing ribs 8, which are used in conjunction with the Z-shaped plate 55.

[0034] As a technical optimization of this utility model, the setting of the reinforcing rib 8 can assist the Z-shaped plate 55 in its work and at the same time play a reinforcing role, avoiding the phenomenon of deformation caused by excessive load on the Z-shaped plate 55.

[0035] refer to Figure 2 The surface of the pull rod 51 is provided with anti-slip grooves, and the pull rod 51 is used in conjunction with the triangular plate 52.

[0036] As a technical optimization of this utility model, the design of the pull rod 51 increases frictional resistance and prevents the pull rod 51 from slipping during hand operation.

[0037] The working principle and usage process of this utility model: During use, hold the handle 43. The handle 43 drives the L-shaped contact plate 42 and the slider 41 to move synchronously. The slider 41 moves stably along the surface of the balance bar 3 until the L-shaped contact plate 42 is adjusted to fit the material width. Then, manually pull the pull rod 51 to both sides. The pull rod 51 moves to both sides, causing the triangular plate 52 to move accordingly. The movement of the triangular plate 52, in conjunction with the guide groove 6, forces the insertion rod 57 to move upward. The upward movement of the insertion rod 57 causes the fixing plate 56 and the Z-shaped plate 55 to move accordingly. The upward movement of the Z-shaped plate 55... The L-shaped clamp 54 moves along the vertical bar 53 and stretches the return spring 7. Finally, the L-shaped clamp 54 is locked onto the side away from the balance bar 3 and fixed to the position of the fixing box 45. The fixed position of the fixing box 45 fixes the position of the slider 41 and the L-shaped contact plate 42. Then, the operator holds the material through the L-shaped contact plate 42 and works with the rolling machine body 1 to perform the winding operation. The material cooperates with the roller 44 to reduce the frictional resistance between the L-shaped contact plate 42 and the material. The operator only needs to lift the material and cooperate with the L-shaped contact plate 42 to complete the conveying.

[0038] In summary, this rolling machine for processing ventilation ducts, through the coordinated use of the rolling machine body 1, fixing block 2, balance bar 3, placement mechanism 4, slider 41, L-shaped contact plate 42, handle 43, rod 44, fixing box 45 and positioning mechanism 5, solves the safety problem of existing rolling machines requiring manual handling of materials during operation, where fingers may easily get caught if they are too close to the machine.
