Each rotation of the turntable can realize the replacement of the labeling mold once, which is convenient for replacing the labeling mold of the laundry tablet. There is no need to stop the machine for manual operation, thereby improving the work efficiency of the laundry tablet labeling machine.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a quick-change mold structure of a laundry tablet labeling machine, including a processing table and a labeling mechanism installed on the processing table, the labeling mechanism including a push rod and a mounting plate fixedly connected to the output end of the push rod, the lower end surface of the mounting plate is fixedly connected to a support frame, the lower end surface of the support frame is rotatably connected to a turntable, a plurality of labeling components distributed in an annular array are arranged in the circumferential direction of the turntable, and a driving device for driving the turntable to intermittently rotate is arranged on the support frame.

[0007] By adopting the above technical scheme, during the process of pressing labels on the laundry sheets, the part of the laundry sheets to be pressed is prevented from being placed on the processing station on the workbench, and then the mounting plate and the support frame are driven downward by the push rod, and the turntable on the support frame drives the pressing label assembly to press down together to complete the pressing label on the laundry sheets. When pressing labels on laundry sheets of different styles, it is necessary to replace the pressing label mold, and the turntable is driven to rotate by the driving device. Each rotation of the turntable is a fixed angle. After completing one rotation, the pressing label assembly on the next group of turntables will come to the position corresponding to the processing station to perform the pressing label operation. The molds in each of the ring-distributed pressing label assemblies are different, which can meet the pressing label requirements of various laundry sheets. The replacement is convenient, and there is no need to stop the machine during the replacement process, thereby improving the efficiency of pressing labels on the laundry sheets.

[0008] The utility model is further configured as follows: the driving device includes a groove wheel and a dial rotatably connected to the support frame, the turntable is fixedly connected to the groove wheel, a dial block is fixedly connected to the surface of the dial, a plurality of slots for the dial block to be inserted into are arranged on the side wall of the groove wheel, the number of the slots corresponds to the pressure mark assembly, and a motor for driving the dial to rotate is installed on the support frame.

[0009] By adopting the above technical solution, when it is necessary to rotate the turntable to replace the pressure mark component corresponding to the processing station, the motor drives the dial to rotate, and when the dial block on the dial is transferred into the slot on the groove wheel, the dial will drive the groove wheel to rotate together, and the groove wheel will drive the turntable to rotate until the dial block is transferred out of the slot. Since the slots are distributed at fixed intervals, the groove wheel can drive the turntable to rotate a fixed angle each time it rotates, and each rotation can just complete the replacement of the pressure mark component, making the replacement of the pressure mark component more convenient and quick.

[0010] The utility model is further configured as follows: the pressure label assembly includes a rotating rod with one end rotatably connected to the turntable via a rotating shaft, the end of the rotating rod away from the turntable is fixedly connected to the pressure label mold, a torsion spring is sleeved on the rotating shaft, and the two ends of the torsion spring are respectively fixedly connected to the rotating shaft and the turntable, when the torsion spring is in an initial state, the rotating rod tilts upward, and the lower end surface of the support frame is fixedly connected to a resistance block, and when the rotating rod rotates to resist the lower end surface of the resistance block, the rotating rod and the pressure label mold are in a horizontal state.

[0011] By adopting the above technical scheme, when the rotating rod and the label pressing mold have not rotated to the label pressing station, the torsion spring is in the initial state, and the rotating rod will tilt upward at this time. The rotating rod and the label pressing mold rotated to the label pressing station will be pressed by the resistance block and rotated downward to a horizontal state when the turntable rotates to the processing station. In this way, when pressing down, the label pressing mold that is not at the label pressing station is upturned and will not touch the laundry sheet on the workbench.

[0013] By adopting the above technical solution, when the rotating rod and the stamping mold rotate to the stamping station, the rotating rod will first contact the lower end surface of the guide block, and gradually rotate to a horizontal state through the guide block, making the transformation of the rotating rod smoother.

[0014] The utility model is further configured as follows: a side of the dial close to the dial block is fixedly connected to a limiting block, both ends of the limiting block are provided with convex arcs, and an outer wall of the groove wheel is provided with a concave arc that cooperates with the convex arc.

[0015] By adopting the above technical solution, when the dial drives the groove wheel to rotate, the convex arc on the limit block will rotate along the concave arc on the groove wheel, and the two cooperate with each other to make the dial and the groove wheel more stable during the rotation process.

[0016] The utility model is further configured as follows: the lower end surfaces of the guide block and the abutment block are both provided with universal balls, and the universal balls are fitted with the surface of the rotating rod.

[0017] By adopting the above technical solution, when the rotating rod comes into contact with the guide block and the resistance block, the universal ball will roll along the surface of the rotating rod, thereby reducing the friction between the rotating rod and the guide block and the resistance block.

[0018] The utility model is further configured as follows: a laser marking lamp is fixedly connected to the lower end surface of the marking die.

[0019] By adopting the above technical solution, the laser marking light will illuminate vertically downward and be positioned on the surface of the workbench, so that the points to be processed of the laundry tablets can be positioned more accurately.

[0020] In summary, the utility model has the following beneficial effects:

[0021] The utility model provides a driving device to drive the turntable to rotate, and each rotation of the turntable can realize the replacement of the label pressing mold once, which is convenient for replacing the label pressing mold of the washing tablet, and there is no need to stop the machine for manual operation, thereby improving the working efficiency of the washing tablet label pressing.
