Description

Technical Field

[0001] This utility model belongs to the field of conveying device technology, specifically relating to a plate power conveying mechanism and a plate production line. Background Technology

[0002] During the production process of polycarbonate sheets or solid polycarbonate sheets, the material is extruded and shaped by the extruder head, and after the cooling process, it is cut to a fixed length.

[0003] In existing technology, after polycarbonate sheets or solid sheets undergo initial cooling by cooling rollers, they also undergo a long-stroke air cooling process before edge trimming. To prevent deformation during the transfer process, multiple parallel and spaced transfer rollers are typically installed between the cooling rollers and the edge trimming rollers to support the polycarbonate sheets or solid sheets. However, because the polycarbonate sheets or solid sheets are not fully cooled and remain somewhat softened, the lower surface of the sheet experiences reverse forces from the stationary support rollers when in contact with them. This often results in surface indentations or deformation, and can also cause surface scratches, especially with relatively thick sheets (which are heavier and cool more slowly), affecting the final product quality. Utility Model Content

[0004] This utility model provides a sheet power conveying mechanism and a sheet production line, which aims to solve the problem of poor practicality caused by surface damage due to the reverse force of each support roller during the production of polycarbonate sheets or solid sheets.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a plate power conveying mechanism, comprising:

[0006] Connector;

[0007] Support rollers are provided at intervals along the conveying direction of the sheet material; each support roller is provided along a horizontal direction perpendicular to the conveying direction of the sheet material and is rotatably mounted on the connecting frame.

[0008] A drive shaft is rotatably mounted on the connecting frame and is positioned along the transmission direction of the plate.

[0009] A drive assembly for rotating the drive shaft;

[0010] Multiple transmission belts are provided, each transmission belt corresponds to each of the support rollers, one end of each transmission belt is sleeved on the drive shaft, and the other end is sleeved on the corresponding support roller;

[0011] As the sheet material is transferred, the drive shaft drives each of the support rollers to rotate synchronously via the transmission belts, so that the linear velocity of each support roller is consistent with the transfer speed of the sheet material.

[0012] In one possible implementation, the driving component includes:

[0013] The driver, fixed on the connecting frame, has a power end arranged parallel to the drive shaft;

[0014] The chain drive structure is connected to the power end and the drive shaft respectively.

[0015] In one possible implementation, each of the drive belts is located at one end of the corresponding support roller.

[0016] In one possible implementation, each of the supporting rollers has an annular groove at one end for the corresponding drive belt to be wound around.

[0017] In one possible implementation, a plurality of fixed cylinders are fixedly connected to the connecting frame, each fixed cylinder is arranged in a one-to-one correspondence with each of the supporting rotating rollers, and each fixed cylinder is coaxially arranged with the corresponding supporting rotating roller.

[0018] In this configuration, the end of the support roller connected to the transmission belt is designated as the power end; each of the fixed cylinders is located on the side of the connecting frame closer to the power end. Each fixed cylinder is used to accommodate one of the transmission belts during the transmission of thin and lightweight sheet materials.

[0019] In one possible implementation, the drive shaft is located below each of the support rollers;

[0020] The connecting frame is provided with a bearing seat for rotatably connecting the drive shaft.

[0021] In one possible implementation, the outer wall surface of each of the supporting rollers is covered with a chrome-plated polished layer.

[0022] This utility model also provides a sheet metal production line, including the above-mentioned sheet metal power conveying mechanism.

[0023] Compared with existing technologies, the sheet metal power conveying mechanism provided in this implementation features a rotatable connection between each support roller and the connecting frame. The support rollers are spaced apart along the conveying direction of the sheet metal, ensuring support for the conveyed sheet metal. The drive shaft, mounted on the connecting frame, is perpendicular to each support roller and is powered by multiple transmission belts. This ensures direct power transmission from the drive shaft to each support roller, enabling synchronous rotation to adapt to the sheet metal's conveying speed. It also prevents friction between the lower surface of the sheet metal and the support rollers, and avoids a reverse force exerted by the support rollers on the lower surface of the sheet metal, effectively preventing damage to the lower surface and ensuring final product quality. The drive shaft is driven by a drive assembly, ensuring a reliable power supply. Attached Figure Description

[0034] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] The following is a preliminary explanation of the plate power conveying mechanism provided by this utility model:

[0036] After polycarbonate sheets or solid sheets are extruded and shaped, they pass through cooling rollers for cooling. However, this cooling only achieves partial temperature reduction; the sheets still retain a certain temperature and are somewhat softened. Therefore, before subsequent edge trimming, they undergo a long air-cooling process, typically 2-3 meters. To prevent the sheets from being suspended in the air during this process, multiple transfer rollers are installed, primarily for supporting the sheets. However, these transfer rollers are not powered; they either rotate as the sheets are transferred (creating rolling friction) or remain stationary (creating sliding friction). Due to the softening of the sheets, regardless of the type of friction, the transfer rollers exert a directional force on the lower surface of the sheets. This force leads to defects such as scratches, indentations, and deformation on the lower surface. This is especially problematic for thicker sheets with greater weight, ultimately resulting in products that fail to meet quality requirements.

[0037] Therefore, please refer to them together. Figure 1 and Figure 2 The sheet metal power conveying mechanism and sheet metal production line provided by this utility model will now be described. The sheet metal power conveying mechanism includes a connecting frame 10, support rollers 20, a drive shaft 30, a drive assembly 40, and transmission belts 50. The support rollers 20 are spaced apart along the sheet metal conveying direction. Each support roller 20 is arranged horizontally perpendicular to the sheet metal conveying direction and rotatably mounted on the connecting frame 10. The drive shaft 30 is rotatably mounted on the connecting frame 10 and is arranged along the sheet metal conveying direction. The drive assembly 40 can drive the drive shaft 30 to rotate. Multiple transmission belts 50 are provided, each corresponding to one of the support rollers 20. One end of each transmission belt 50 is sleeved on the drive shaft 30, and the other end is sleeved on the corresponding support roller 20.

[0038] As the sheet material is transferred, the drive shaft 30 drives each support roller 20 to rotate synchronously via each transmission belt 50, so that the linear speed of each support roller 20 is consistent with the transfer speed of the sheet material.

[0039] In this embodiment, the axes of the shafts at both ends of each transmission belt 50 are vertically arranged, which ensures that the power of the drive shaft 30 covers each support roller 20.

[0040] Compared with the prior art, the sheet metal power conveying mechanism provided in this embodiment features a rotatable connection between each support roller 20 and the connecting frame 10. The support rollers 20 are arranged at intervals along the conveying direction of the sheet metal, ensuring support for the conveyed sheet metal. The drive shaft 30, mounted on the connecting frame 10, is perpendicular to each support roller 20 and is poweredly connected to each support roller 20 via multiple transmission belts 50. This ensures that the power from the drive shaft 30 is directly transmitted to each support roller 20, causing them to rotate synchronously to adapt to the conveying speed of the sheet metal. This avoids friction between the lower surface of the sheet metal and each support roller 20, and prevents each support roller 20 from exerting a reverse force on the lower surface of the sheet metal, effectively preventing damage to the lower surface of the sheet metal and ensuring the final product quality. The drive shaft 30 is driven by the drive assembly 40, ensuring a reliable power supply to the drive shaft 30.

[0041] It should be noted that the connecting frame 10 in this embodiment has one end corresponding to the cooling rollers of the board production line and the other end corresponding to the trimming mechanism. Of course, it is not limited to the two components mentioned above, but also applicable to the other two components of the board production line.

[0042] In some embodiments, the driving component 40 described above may employ, for example... Figures 1 to 3 The structure shown. See also Figures 1 to 3 The drive assembly 40 includes a driver 41 and a chain drive structure 42. The driver 41 is fixed on the connecting frame 10 and has a power end arranged parallel to the drive shaft 30. The chain drive structure 42 is connected to both the power end and the drive shaft 30.

[0043] The driver 41 is directly fixedly mounted on the connecting frame 10. To ensure a secure connection of the driver 41, a downwardly extending vertical arm can be provided on the connecting frame 10. The power end of the driver 41 is parallel and spaced apart from the drive shaft 30, which facilitates power transmission. The driver 41 can support the drive motor and the reducer adapted to the drive motor; the power end can be the output shaft of the reducer.

[0044] See also Figure 1 The chain drive structure 42 can ensure the stable transmission of power. The chain drive structure 42 may include two sprockets and a transmission chain. The two sprockets are coaxially fixed on the power end and the drive shaft 30 respectively, and are in the same vertical plane. The transmission chain can be wound around the outer circumference of the two sprockets. The chain drive structure 42 is the prior art and is well known to those skilled in the art in terms of power transmission, so it will not be described in detail here.

[0045] In this embodiment, power is transmitted to the drive shaft 30 through the driver 41 and the chain drive structure 42, thereby ensuring that the drive shaft 30 transmits power to each support roller 20 through each transmission belt 50. This effectively avoids the lower surface of the board being subjected to the reverse force from each support roller 20, eliminates the sliding friction and rolling friction on the lower surface of the board, and effectively ensures the quality of the board.

[0046] In some embodiments, the drive belt 50 may be as follows: Figure 1 and Figure 3 The structure shown. See also Figure 1 and Figure 3 Each drive belt 50 is located at one end of the corresponding support roller 20.

[0047] This involves the sheet material moving above each supporting roller 20 and being centered relative to each supporting roller 20. This step of the transmission belt 50 can effectively avoid interference with the sheet material, thereby ensuring the quality of the sheet material.

[0048] In some embodiments, the aforementioned support roller 20 may be as follows: Figure 4 The structure shown. See also Figure 4 Each support roller 20 has an annular groove at one end for the corresponding transmission belt 50 to be wound around.

[0049] The annular groove effectively limits the transmission belt 50, preventing it from detaching from the corresponding support roller 20 during operation, thus ensuring stable power transmission and guaranteeing the final product quality to a certain extent.

[0050] In some embodiments, the connecting frame 10 may be adopted as follows: Figure 4 The structure shown. See also Figure 4 Multiple fixed cylinders 11 are fixedly connected to the connecting frame 10, and each fixed cylinder 11 is arranged in a one-to-one correspondence with each supporting roller 20. Each fixed cylinder 11 is coaxially arranged with the corresponding supporting roller 20. The end of the supporting roller 20 connected to the transmission belt 50 is designated as the power end. Each fixed cylinder 11 is located on the side of the connecting frame 10 closer to the power end.

[0051] The fixed cylinders 11 ensure that when the conveyor belts 50 are not in use, they can be moved or transferred to their corresponding fixed cylinders 11, at which point the support rollers 20 are in a free state. For heavier plates, which are more prone to defects due to the reverse force from the support rollers 20 during transport, this is less problematic. However, for thinner and lighter plates, which cool relatively completely after cooling, no driving force is needed for the support rollers 20. To ensure rolling friction between the support rollers 20 and the plate, the conveyor belts 50 can be removed to avoid damping on the support rollers 20, thus saving energy, maintaining plate quality, and ensuring high adaptability.

[0052] In some embodiments, the drive shaft 30 and each support roller 20 can be configured as follows: Figure 1 and Figure 3 The structure shown. See also Figure 1 and Figure 3 The drive shaft 30 is located below each support roller 20, which avoids interference with each support roller 20. At the same time, it also ensures that each transmission belt 50 is located below each support roller 20, avoiding the occupation of the space above each support roller 20, and facilitating manual operation of the plates on each support roller 20 by the staff.

[0053] The connecting frame 10 is provided with a bearing seat 12 for the drive shaft 30 to be rotatably connected. The bearing seat 12 ensures the rotatable connection of the drive shaft 30, thereby ensuring the stable rotation of the drive shaft 30.

[0054] In some embodiments, the aforementioned support roller 20 may be as follows: Figure 1 The structure shown. See also Figure 1 Each supporting roller 20 has a chrome-plated polished layer on its outer wall surface.

[0055] Chrome plating and polishing is a metal surface treatment process. A thin layer of chrome is applied to the outer wall of the support roller 20 by electroplating, and then polishing is used to make the chrome layer have a mirror-like bright effect. This can further reduce the risk of adhesion, roller sticking and scratches, and indirectly alleviate the severity of indentation and reduce roller contamination. When the support rollers 20 rotate synchronously with the sheet material, surface defects of the sheet material can be directly avoided, effectively ensuring product quality.

[0056] This application also provides a sheet metal production line, including the aforementioned sheet metal power conveying mechanism.

[0057] Compared with the prior art, the sheet metal production line provided in this embodiment can adapt to the transmission speed of the sheet metal through the set sheet metal power conveying mechanism, which can avoid friction between the lower surface of the sheet metal and each support roller 20, and avoid each support roller 20 exerting a reverse force on the lower surface of the sheet metal, thereby effectively avoiding damage to the lower surface of the sheet metal and ensuring the final product quality.

[0058] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
