[0002] The CZ purlin machine is a specialized machine used to manufacture C- and Z-shaped purlins. This type of machine is commonly used in the construction industry, particularly in steel structures, to produce C- and Z-shaped purlins that support the roof and wall structures.

[0003] Currently, existing CZ purlin machines typically feature a high degree of automation, enabling a series of fully automated production processes, including coil forming and reshaping. For example, the utility model patent with Chinese Patent Authorization Publication No. CN212238715U discloses a CZ-type purlin integrated machine comprising a plurality of pressing roller mechanisms, including a frame, an upper pressing roller, and a lower pressing roller. The pressing roller mechanisms are arranged into left and right upper and lower folding rows. The adjustable folding rollers can be switched between an upper folding position, forming an upward folding edge on the steel plate, and a lower folding position, forming a downward folding edge on the steel plate. This allows for the automated production of both C- and Z-shaped purlins on a single machine. However, this solution presents the following practical problems: Due to the need for products of varying plate thicknesses, the CZ-type purlin integrated machine described above is not suitable for forming coils of varying plate thicknesses, thus requiring improvement. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the utility model provides a CZ type adjustment device that is adaptable to thick plates.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example: Please refer to Figures 1 to 9 This embodiment provides a CZ type adjustment device for adapting to thick plates, including a gantry 1 and a supporting wheel group 2 installed on the gantry 1 and a roller group 3 arranged on an external frame. The supporting wheel group 2 cooperates with the roller group 3 to shape the passing coil 4 to form the required C-shaped purlin or Z-shaped purlin.

[0027] In this embodiment, the roller assembly 2 includes a roller body 201 and a connecting shaft 202. The roller body 201 is disposed on one end of the connecting shaft 202. The roller body 201 is tilted relative to the connecting shaft 202 to facilitate subsequent shaping of the coil 4. The roller body 201 is disposed close to the roller assembly 3. A gap 5 is left between the roller body 201 and the roller assembly 3 for the coil 4 to pass through. When the coil 4 is conveyed, the coil 4 is conveyed by the roller assembly 3. When passing through the gap 5, the coil 4 can be bent by the roller body 201, thereby performing the corresponding shaping work. The connecting shaft 202 is movably arranged to pass through the gantry 1; a locking block 6 is fixedly arranged on the side wall of the gantry 1 away from the wheel body 201, and a connecting hole 7 is provided on the locking block 6 to pass through the locking block 6. A first eccentric sleeve 8 is provided at a position of the locking block 6 away from the gantry 1 side, and one end of the first eccentric sleeve 8 is rotatably connected to the connecting hole 7. The connecting shaft 202 is arranged to pass through the first eccentric sleeve 8, and the connecting shaft 202 and the first eccentric sleeve 8 are eccentrically matched, and the other end of the first eccentric sleeve 8 is fixedly provided with an adjusting sleeve 9.

[0028] Through the above arrangement, when the gap 5 between the supporting roller body 201 and the roller assembly 3 needs to be adjusted, the first eccentric sleeve 8 is driven to rotate by rotating the adjusting sleeve 9. At this time, due to the eccentric fit between the connecting shaft 202 and the first eccentric sleeve 8, the connecting shaft 202 will perform an eccentric movement adapted to the movement of the first eccentric sleeve 8, thereby driving the supporting roller body 201 to move adapted, that is, the gap 5 between the supporting roller body 201 and the roller assembly 3 can be adjusted to adapt to changes in the thickness of the passing coil 4. During this process, the roller assembly 3 should also be adjusted accordingly to adapt to the thickness of the coil 4 that needs to pass through.

[0029] The support wheel assembly 2 also includes a connecting handle 203, which is fixedly mounted on the end of the connecting shaft 202 away from the support wheel body 201. A change handle 10 is also provided at the position of the locking block 6 away from the support wheel body 201. The change handle 10 is connected to the connecting handle 203. In this embodiment, the change handle 10 is provided with a mating hole 13, and the connecting handle 203 is provided through the mating hole 13 to connect with the change handle 10. The specific shape of the mating hole 13 can be determined according to actual conditions, so long as the change handle 10 can slide along the connecting handle 203 through the provision of the mating hole 13 and can drive the connecting handle 203 to rotate. In this embodiment, the mating hole 13 is a special-shaped hole structure with a rectangular center and arc-shaped sides. Two symmetrically arranged plug-in columns 11 are provided on the side wall of the changing handle 10 close to the locking block 6, and a second eccentric sleeve 12 is provided on the side wall of the locking block 6 close to the changing handle 10, which is arranged one-to-one with the two plug-in columns 11. The plug-in columns 11 on both sides are movably inserted into the second eccentric sleeve 12 on the corresponding side, and the plug-in column 11 and the second eccentric sleeve 12 are eccentrically matched.

[0030] With the above arrangement, when the first eccentric sleeve 8 rotates to move the connecting shaft 202, the movement of the connecting shaft 202 will inevitably drive the connecting handle 203 to move. After the connecting handle 203 moves, it will drive the changing handle 10 to move under the action of the matching hole 13. To accommodate this movement process, the two plug-in posts 11 can eccentrically fit with the second eccentric sleeve 12 to enable relative movement between the changing handle 10 and the locking block 6, thereby allowing the changing handle 10 to adapt to the movement of the connecting handle 203. Under the eccentric cooperation between the plug-in posts 11 and the second eccentric sleeve 12, the changing handle 10 can follow the movement of the connecting handle 203. When the type of the coil 4 needs to be adjusted, the shape-changing handle 10 is pulled to move the plug-in columns 11 on both sides away from between the second eccentric sleeves 12. Then, the shape-changing handle 10 is rotated 180 degrees to drive the rotating handle to rotate. After the rotating handle is rotated, the connecting shaft 202 is used to drive the roller body 201 to move, thereby completing the adjustment of the posture of the roller body 201 and realizing the switching of the shape of the coil 4, that is, C-type and Z-type. After the adjustment is completed, the shape-changing handle 10 is pushed to re-insert the plug-in columns 11 on both sides into the second eccentric sleeves 12.

[0031] In order to prevent the change handle 10 from falling off the connecting handle 203, in this embodiment, a limit block 14 is further provided on the end of the connecting handle 203 away from the connecting shaft 202. The limit block 14 is set so that it cannot pass through the matching hole 13, so as to prevent the change handle 10 from falling off from the connecting handle 203.

[0032] In order to facilitate the rotation of the connecting shaft 202 , a rotating bearing 15 is further provided on the end of the connecting shaft 202 away from the wheel assembly 2 . The rotating bearing 15 is located between the first eccentric sleeve 8 and the changing handle 10 .

[0033] In order to facilitate the fixation of the first eccentric sleeve 8 and to prevent the first eccentric sleeve 8 from rotating during the forming process and causing errors in the forming work, a latch 16 is further provided on one side wall of the locking block 6. One end of the latch 16 is movably inserted into the connecting hole 7 and is tightly arranged with the first eccentric sleeve 8, and the other end of the latch 16 is arranged to extend out of the locking block 6. The extended end of the latch 16 is fixedly connected to the locking block 6 by locking the locking nut 17. Through the above arrangement, when the first eccentric sleeve 8 does not need to rotate, the first eccentric sleeve 8 can be fixed by pressing the latch 16 against the first eccentric sleeve 8 to prevent the first eccentric sleeve 8 from rotating during the forming process of the coil 4. When the first eccentric sleeve 8 needs to rotate, the locking nut 17 is removed and the latch 16 is pulled outward to make it leave the first eccentric sleeve 8. At this time, the first eccentric sleeve 8 can be driven to rotate by rotating the adjusting sleeve 9 to perform corresponding adjustment work.

[0034] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
