Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of strapping machines, in particular to an automatic friction bonding strapping machine core. Background Art
[0002] A strapping machine is a mechanical device used to bundle or pack items. It uses strapping tape or other materials to tightly secure items together to ensure safety and stability during transportation, storage, or display. Strapping machines are widely used in many industries, including manufacturing, logistics, warehousing, food packaging, and other fields. The strapping core in the strapping machine is one of the important components of the strapping machine. During the strapping process, the strapping core is usually connected to a drive device to help pull the strapping tape and guide it to the bundled object. When replacing an existing strapping core, workers are usually required to align the new core with the bearings and connection points on the frame and fix it with screws or locking devices. Workers need to use tools to install and disassemble it. Each replacement requires tools to loosen and tighten the screws one by one, which takes a long time and reduces overall efficiency.
[0003] Therefore, it is urgent to provide an automatic friction bonding strapping machine core to solve the above problems. Utility Model Content
[0004] The technical problem to be solved by the utility model is that the efficiency of core replacement is low.

[0006] Through the above technical solution, the piston rods of the two first cylinders and the second cylinder are extended or retracted at the same time, and the roller shaft can be placed horizontally between the two positioning sockets on the mounting frame, so that the strapping installation roller can be quickly replaced during use.
[0007] The utility model is further configured as follows: one end of the first cylinder piston rod is rotatably connected to a rotating shaft, the top end of the second cylinder piston rod is rotatably connected to a positioning socket, and the other end of the rotating shaft is also fixedly connected to a positioning socket.
[0008] The utility model is further configured as follows: a long gear ring is fixedly connected to the outer wall of the rotating shaft, a fixed connecting frame is installed in the connecting seat, a servo motor is provided on the upper end of the fixed connecting frame, the servo motor is fixedly connected to the fixed connecting frame, a drive shaft is fixedly installed on the output end of the servo motor, and a driving gear is fixedly connected to the drive shaft.
[0009] Through the above technical solution, the output end of the servo motor will drive the driving gear to rotate synchronously through the driving shaft, and then the driving gear can be used to drive the long gear ring engaged with it to rotate, and then the rotating shaft and the roller shaft can be driven to rotate synchronously, so that the strapping belt on the roller shaft is evenly released for strapping of the package.
[0010] The utility model is further configured as follows: the strapping belt installation roller includes a roller shaft inserted between two positioning sockets, both ends of the roller shaft are provided with connecting slots, and the inner sides of the two connecting slots are provided with frustum grooves.
[0011] Through the above technical solution, the piston rods of the first cylinder and the second cylinder will shrink synchronously, so that the two positioning sockets will be separated from the roller shaft. At this time, under the action of gravity, the strapping installation roller will automatically fall onto the installation base. The staff can reinstall a new strapping installation roller to continue the strapping work.
[0012] The utility model is further configured such that: the frustum groove and the positioning socket match each other.
[0013] The utility model is further configured as follows: the driving gear and the long gear ring are engaged for transmission.
[0014] The beneficial effects of the utility model are as follows:
[0015] The utility model simultaneously extends or contracts the piston rods of the two first cylinders and the second cylinder, and the roller shaft can be horizontally placed between the two positioning sockets on the mounting frame, so that the strapping strap mounting roller can be quickly replaced during use. The strapping machine core that can be quickly installed and disassembled greatly reduces the conversion time of the production line, especially in the small-batch production of multiple varieties. It can quickly adapt to the use requirements of strapping straps for different products, and at the same time reduce dependence on manual labor. The operator only needs to complete the replacement in simple steps, which greatly reduces labor costs. BRIEF DESCRIPTION OF THE DRAWINGS
