[0017] 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.
[0018] Please see Figs. 1-3This utility model discloses a special feeding device for printing equipment, including a bracket 1. A hollow rotating platform 2 is installed on the upper part of the bracket 1, and a fixed plate 3 is installed on the turntable of the hollow rotating platform 2. Feeding components 4 are installed on the left and right ends of the fixed plate 3, and a roll 5 is fitted on the feeding components 4. Feeding components 4 are installed on both sides of the fixed plate 3, and the feeding components 4 are provided with upper and lower stations. For example, the lower station disconnects the transmission under the action of the magnetic powder clutch 43, allowing the upper station to feed first. After the upper station finishes feeding, the transmission is disconnected under the action of the magnetic powder clutch 43, and the transmission of the lower station is connected to continue feeding. At this time, the replacement of the roll is realized. After the feeding component 4 on one side of the fixed plate 3 finishes feeding, the hollow rotating platform 2 is rotated 180° to continue the above operation steps. This design does not require frequent disassembly and assembly, which can avoid long-term downtime of printing equipment and greatly improve the feeding efficiency.
[0019] The feeding assembly 4 includes a lower rotating shaft 41, an upper rotating shaft 42, a magnetic powder clutch 43, and a motor 44. One end of the lower rotating shaft 41 and the upper rotating shaft 42 are each equipped with a limit sleeve 45, and the other end of the lower rotating shaft 41 and the upper rotating shaft 42 are each threadedly connected with a limit nut 46. One end of the lower rotating shaft 41 and the upper rotating shaft 42 are each fixedly connected to a magnetic powder clutch 43, and the other end of the magnetic powder clutch 43 is equipped with a first synchronous pulley 47. The output shaft end of the motor 44 is equipped with a second synchronous pulley 48, and the second synchronous pulley 48 is connected to the first synchronous pulley 47 through a synchronous belt.
[0020] Specifically, a conductive slip ring 6 is embedded in the fixed plate 3, and the conductive slip ring 6 and the turntable of the hollow rotating platform 2 are located on the same axis.
[0021] In this embodiment, the main function of the conductive slip ring 6 is to solve the problem of wire entanglement when the mechanical equipment rotates 360 degrees, and to realize the transmission of signals and power between two relatively rotating mechanisms. The conductive slip ring 6 consists of two parts: a stator and a rotor. It can stably transmit signals in the rotating state and avoid the problems of entanglement or breakage that may occur in traditional wires during rotation.
[0022] Specifically, one terminal of the conductive slip ring 6 is electrically connected to the motor 44 and the magnetic powder clutch 43 via wires, and the other terminal of the conductive slip ring 6 is connected to the power supply via wires.
[0023] In this embodiment, the motor 44 and the magnetic powder clutch 43 are connected to the power supply or control system through the conductive slip ring 6. The working principle of the magnetic powder clutch 43 is to transmit torque through electromagnetic principle and magnetic powder. When the coil is energized, the magnetic powder generates magnetic flux under the action of magnetic lines of force, so that the output shaft and the input shaft become a rigid body and rotate. When overloaded, slip is generated to achieve the purpose of transmitting torque. When the coil is not energized, the magnetic powder is pressed against the inner wall of the clamping ring under the action of centrifugal force, and the output shaft and the input shaft are not in contact. At this time, it is in an idling state, thereby realizing the output or disconnection of transmission torque.
[0024] Specifically, the lower rotating shaft 41 and the upper rotating shaft 42 are respectively mounted on the upper and lower ends of the fixed plate 3 via bearings, and the drum 5 is fitted onto the lower rotating shaft 41 and the upper rotating shaft 42.
[0025] In this embodiment, the lower rotating shaft 41 and the upper rotating shaft 42 are used for the installation of the drum 5 and to drive the drum 5 to unload material. When disassembling and assembling the drum 5, the limit nut 46 is removed to take out the drum 5. After replacing it with a drum 5 containing the rolled material, the limit nut 46 is tightened. The operation is simple.
[0026] Specifically, the upper and lower ends of the fixed plate 3 are hinged to the swing arms 7 by pins, and the swing arms 7 are threaded with hand-tightening bolts 8, which are fastened to the fixed plate 3.
[0027] In this embodiment, the swing arm 7 is a support structure used for the installation and fixation of the guide roller 9, and the angle of the swing arm 7 can be finely adjusted by the action of the hand-tightening bolt 8.
[0028] Specifically, a guide roller 9 is mounted on the swing arm 7 via a bearing, and the guide roller 9 is positioned close to the edge of the drum 5.
[0029] In this embodiment, the main function of the guide roller 9 is to guide and support the rolled material, ensuring its stable operation during the conveying process.
[0030] In use, feeding components 4 are installed on both sides of the fixed plate 3, and the feeding components 4 are set with upper and lower stations. The upper and lower rollers 5 are driven by the motor 44 to feed the material. During feeding, for example, the transmission of the lower station is disconnected under the action of the magnetic powder clutch 43, allowing the upper station to feed the material first. After the upper station finishes feeding the material, the transmission is disconnected under the action of the magnetic powder clutch 43, and the transmission of the lower station is connected to continue feeding the material. At this time, the material roll is changed. After the feeding component 4 on one side of the fixed plate 3 finishes feeding the material, it is rotated 180° by the hollow rotating platform 2 to continue the above operation steps. This design does not require frequent disassembly and assembly, which can avoid long-term downtime of printing equipment and greatly improve feeding efficiency.
[0031] In summary, this dedicated feeding device for printing equipment has feeding components 4 installed on both sides of the fixed plate 3. The feeding components 4 are configured with upper and lower stations. For example, the lower station disconnects the transmission under the action of the magnetic powder clutch 43, allowing the upper station to feed material first. After the upper station finishes feeding material, the transmission is disconnected under the action of the magnetic powder clutch 43, and the transmission of the lower station is reconnected to continue feeding material. At this time, the material roll can be replaced. After the feeding component 4 on one side of the fixed plate 3 finishes feeding material, it is rotated 180° by the hollow rotating platform 2 to continue the above operation steps. This design does not require frequent disassembly and assembly, which can avoid long-term downtime of the printing equipment and greatly improve the feeding efficiency.
