Description

Technical Field

[0001] This utility model relates to a sheet metal conveying platform at the inlet of a drying furnace. Background Technology

[0002] In the production of tin cans, one step requires feeding the sheet metal into a drying oven for drying. Traditionally, multiple conveyor rollers are used to transport the sheet metal. Since these rollers are made of materials like aluminum, the sheet metal easily rubs against them during transport, causing scratches on the surface and affecting its appearance and quality. This, in turn, impacts the quality of the tin cans produced after they are wound into cans. Utility Model Content

[0003] This invention addresses the aforementioned problem by providing a sheet metal conveying platform at the inlet of a drying oven, effectively preventing scratches on the sheet metal surface and improving its aesthetics and quality.

[0004] The present invention is constructed as follows: it includes a frame and a first pulley assembly disposed in the middle of the frame. Second pulley assemblies are symmetrically arranged in front of and behind the first pulley assembly. Each second pulley assembly includes a third pulley assembly and a fourth pulley assembly disposed at intervals. The third pulley assembly and the fourth pulley assembly are connected by a linkage assembly.

[0005] Furthermore, an auxiliary pulley assembly is provided between the two third pulley assemblies.

[0006] Furthermore, the upper surfaces of the belt of the first pulley assembly, the belt of the second pulley assembly, and the auxiliary wheel assembly are flush.

[0007] Furthermore, the first pulley assembly includes a first pulley frame, with a first driving shaft and a first driven shaft respectively arranged on both sides of the first pulley frame. Two first driving pulleys are installed at intervals on the first driving shaft, and two first driven pulleys are installed on the first driven shaft. A first conveyor belt is fitted between the corresponding first driving pulleys and first driven pulleys.

[0008] Furthermore, a left tensioning pulley, a middle tensioning pulley, and a right tensioning pulley are provided below the first pulley frame. The first conveyor belt passes sequentially through the first driving pulley, the first driven pulley, the upper surface of the left tensioning pulley, the lower surface of the middle tensioning pulley, and the upper surface of the right tensioning pulley before connecting with the first driving pulley to form a closed loop.

[0009] Furthermore, the third pulley assembly includes a third driven shaft mounted on the frame, two third driving pulleys mounted on the first driving shaft of the first pulley assembly, and two third driven pulleys mounted on the third driven shaft, with a third conveyor belt fitted between the corresponding third driven pulleys and the third driving pulleys; the fourth pulley assembly includes a fourth driven shaft and a fourth driving shaft mounted on the frame, with two fourth driving pulleys mounted on the fourth driving shaft and two fourth driven pulleys mounted on the fourth driven shaft, with a fourth conveyor belt fitted between the fourth driving pulleys and the fourth driven pulleys.

[0010] Furthermore, the auxiliary wheel assembly includes an auxiliary shaft rotatably connected to the frame and an auxiliary pulley disposed on the auxiliary shaft.

[0011] Furthermore, the linkage assembly includes a third linkage pulley mounted on a third driven shaft, a fourth linkage pulley mounted on a fourth driving shaft, and an auxiliary linkage pulley mounted on an auxiliary shaft. A tensioning roller is provided between the auxiliary linkage pulley and the third linkage pulley. The tensioning roller is fixed to the frame by a tensioning bracket. A linkage belt is fitted between the third linkage pulley, the tensioning roller, the auxiliary linkage pulley, and the fourth linkage pulley. The linkage belt forms a closed loop after passing through the upper surface of the third linkage pulley, the lower surface of the tensioning roller, the upper surface of the auxiliary linkage pulley, the upper surface of the fourth linkage pulley, the lower surface of the fourth linkage pulley, the lower surface of the auxiliary linkage pulley, and the lower surface of the third linkage pulley.

[0013] Furthermore, the input end of the frame is provided with a feeding mechanism, which includes a feeding worktable and multiple belt feeding mechanisms disposed within the feeding worktable.

[0014] Compared with existing technologies, this utility model has the following advantages: The device has a simple structure, reasonable design, and is easy to use. The sheet metal is fed onto the frame by the feeding belt of the feeding mechanism. The first pulley assembly, the first conveyor belt of the second pulley assembly, the third conveyor belt, and the fourth conveyor belt on the frame continue to convey the sheet metal until it reaches the support arm of the rotating discharge mechanism. The support arm then rotates to lift and transport the sheet metal into the drying oven.

[0021] During operation: Sheet metal 400 is fed onto the frame via the feed belt of the feeding mechanism. The first, second, third, and fourth conveyor belts of the first and second pulley assemblies on the frame continue to transport the sheet metal until it reaches the support arm of the rotating discharge mechanism. The rotating support arm then lifts and rotates the sheet metal into the drying oven. During the sheet metal conveying process, because the sheet metal is in contact with and transported by the first, third, and fourth conveyor belts, scratches are effectively avoided, improving the appearance and quality of the sheet metal.

[0022] It is worth noting that when the first pulley assembly is working: the motor drives the first drive shaft to rotate, which in turn drives the first drive pulley to rotate synchronously, thereby driving the first driven shaft and the first driven pulley to rotate, thus driving the first conveyor belt to move; when the third pulley assembly is working: due to the rotation of the first drive shaft and the rotation of the third drive pulley, the third driven shaft and the third driven pulley to rotate, thereby driving the third conveyor belt to move; and the movement of the fourth pulley assembly is achieved by the third driven shaft of the third pulley assembly driving the fourth drive shaft of the fourth pulley assembly to rotate via the linkage assembly, thereby driving the fourth conveyor belt to move synchronously.

[0023] When the linkage component is working: the third driven shaft rotates, which drives the third linkage pulley to rotate. The third linkage pulley drives the fourth linkage pulley, the auxiliary pulley, and the tensioning roller to rotate synchronously via the linkage belt, thereby causing the fourth driving shaft and the auxiliary shaft to rotate as well. The rotation of the fourth driving shaft drives the fourth conveyor belt to move, and the fourth driven shaft rotates.

Two first driving pulleys 204 are installed at intervals on the first driving shaft, and two first driven pulleys 205 are installed on the first driven shaft. A first conveyor belt 206 is sleeved between the corresponding first driving pulleys and first driven pulleys. A support guide 207 is provided below the upper belt of the first conveyor belt. The support guide is fixed to the upper part of the first pulley frame to provide certain support for the upper belt of the first conveyor belt.

[0028] The first active rotating shaft is rotatably coupled to the frame, that is, a bearing A208 is provided between the first active rotating shaft and the frame, and the first active rotating shaft is driven to rotate by a motor 209.

[0029] In this embodiment of the utility model, a left tensioning pulley 210, a middle tensioning pulley 211 and a right tensioning pulley 212 are provided below the first pulley frame. The first conveyor belt 206 passes sequentially through the first driving pulley, the first driven pulley, the upper surface of the left tensioning pulley, the lower surface of the middle tensioning pulley and the upper surface of the right tensioning pulley before connecting with the first driving pulley to form a closed loop.

[0030] The aforementioned left tensioning pulley, middle tensioning pulley, and right tensioning pulley are connected to the first pulley frame via shafts. The left tensioning pulley, middle tensioning pulley, and right tensioning pulley are all rotatable. For example, the left tensioning pulley, middle tensioning pulley, and right tensioning pulley are fixedly connected to their respective shafts, and the shafts are rotatably engaged with the first pulley frame.

[0032] The aforementioned third driven shaft is rotatably coupled with the frame, and the fourth driven shaft and the fourth driving shaft are rotatably coupled with the frame; that is, the third driven shaft, the fourth driven shaft, the fourth driving shaft and the frame are all connected by bearings.

[0034] The aforementioned tensioning roller is connected to the tensioning bracket via a tensioning shaft. The tensioning shaft can rotate with the tensioning bracket. For example, the tensioning shaft and the tensioning bracket can be connected via a bearing, while the tensioning roller and the tensioning shaft are fixed coaxially. Alternatively, the tensioning shaft can rotate directly with the tensioning roller, while the tensioning shaft and the tensioning bracket are fixed. It is sufficient to ensure that the tensioning roller can rotate.

[0035] In this embodiment of the utility model, the output end of the frame is provided with a rotating discharge mechanism 600. The rotating discharge mechanism includes a rotatable discharge main shaft 601 and two rotating bodies 602 disposed on the discharge shaft.

The rotating shaft is on the same driven rotating shaft for feeding; the two ends of the driven rotating shaft for feeding and the two ends of the driven rotating shaft for feeding are respectively rotatably engaged with the feeding frame. The two ends of the driven rotating shaft for feeding and the two ends of the driven rotating shaft for feeding are respectively connected to the feeding frame via bearings. The driven rotating shaft for feeding is driven to rotate by the feeding motor, thereby driving multiple belt feeding mechanisms to work synchronously and convey the iron sheet. Of course, the upper surface of the feeding belt of the multiple belt feeding mechanisms can be slightly higher than the upper surface of the belt of the first belt pulley assembly, so as to facilitate the conveying of the iron sheet to the first belt pulley assembly and the second belt pulley assembly of the frame.
