Description

Technical Field

[0001] The invention relates to the technical field of paper box printing technology, in particular to a flipping and conveying mechanism and technology of a hot stamping machine used for paper box printing. Background Art

[0002] Paper box printing is a process that covers a variety of printing technologies and processes, and is mainly used in the production of packaging products such as paper boxes and cartons. In the process of paper box printing, the hot stamping machine is a mechanical device used to complete the hot stamping process.

[0003] The working principle of the hot stamping machine is mainly based on the principle of heat pressure transfer; specifically, under the action of combined pressure, the electroplated aluminum contacts the hot stamping plate and the substrate, the electric heating plate heats up to make the hot stamping plate have a certain amount of heat, the hot-melt dyeing resin layer and adhesive melt after the electroplated aluminum is heated, the adhesion of the dyeing resin layer decreases, and the viscosity of the special heat-sensitive adhesive increases after melting, the aluminum layer is peeled off from the electroplated aluminum base film and transferred to the substrate. As the pressure is removed, the adhesive quickly cools and solidifies, and the aluminum layer firmly adheres to the substrate, completing the hot stamping process.

[0004] Usually, the workflow of a conventional hot stamping machine is as follows: place the item to be hot stamped on the workbench of the hot stamping machine; turn on the power switch of the hot stamping machine, wait for the machine to preheat to a suitable temperature, and then adjust the temperature control knob of the hot stamping machine to set the temperature to a suitable level according to the material of the item and the requirements of the hot stamping foil; then, place the hot stamping foil at the position where hot stamping is required, ensuring that the foil surface is tightly fitted to the surface of the item; then, press the operation button of the hot stamping machine to press the hot stamping head down and make contact with the hot stamping foil; wait for a while to allow the temperature of the hot stamping head to be transferred to the hot stamping foil, and cause the foil surface to be hot-melted and bonded to the surface of the item; then, gently lift the hot stamping head, tear off the hot stamping foil, and check whether the hot stamping effect meets the requirements. If the hot stamping effect is not satisfactory, you can perform the hot stamping operation again until the ideal effect is achieved; finally, turn off the power switch of the hot stamping machine, wait for the machine to cool down, and clean the residues on the hot stamping head and the workbench.

[0005] Based on this, Chinese patent CN111572188B discloses a hot stamping machine, which includes a mounting frame, a transmission structure, a hot stamping assembly and a transfer assembly. The mounting frame includes a base plate, a first frame and a second frame. The first frame and the second frame are respectively convexly arranged at opposite ends of the base plate. A support plate is arranged on the top of the first frame. The transmission structure is installed on the support plate of the first frame. A heating abutment is arranged on the top of the second frame. A gold foil strip is arranged on the side wall of the heating abutment. The hot stamping assembly includes a support frame, a rotating motor and a fan-shaped hot stamping block. The support frame is installed in the middle of the base plate, the rotating motor is installed on the support frame, the fan-shaped hot stamping block is installed on the output shaft of the rotating motor, the fan-shaped hot stamping block is provided with a hot stamping slope, and the hot stamping slope is inclined relative to the gold foil strip. A support frame is installed on the side of the heating abutment away from the fan-shaped hot stamping block. The transfer assembly includes a fixed frame. A fixed frame, a transfer motor, a lifting motor, a flipping member and multiple suction cups, the fixed frame is fixed on the support plate, the transfer motor is installed on the fixed frame, an L-shaped frame is installed on the output shaft of the transfer motor, the lifting motor is installed on the end of the L-shaped frame, the flipping member includes a connecting rod, a flipping rod and a spring, the connecting rod is fixedly connected to the output shaft of the lifting motor, the top of the flipping rod is rotatably connected to the bottom end of the connecting rod, the bottom end of the flipping rod is provided with a mounting plate, the spring is sleeved on the connecting rod and the flipping rod, and the opposite ends of the spring are respectively connected to the connecting rod and the flipping rod, multiple suction cups are installed on the bottom surface of the mounting plate, the multiple suction cups are used to adsorb the flat workpiece on the transmission structure, the flipping rod is used to abut on the abutting frame and flip relative to the connecting rod under the drive of the transfer motor, so that the flat workpiece slides onto the hot stamping inclined surface of the fan-shaped hot stamping block.

[0006] However, the hot stamping machine disclosed above still has the technical problem of poor transmission effect. Specifically, the hot stamping machine disclosed in the prior art has the following working principle: the lifting motor is used to drive the flipping member to descend so as to use multiple suction cups to absorb the flat workpiece on the transmission structure, and then the lifting motor is raised. The transfer motor drives the flat workpiece to move toward the supporting frame through the L-shaped frame until the flipping rod is abutted against the supporting frame and flipped relative to the connecting rod, so that the flat workpiece is inclined relative to the vertical plane and is roughly parallel to the hot stamping inclined surface. Then, the multiple suction cups are used to release the flat workpiece so that the flat workpiece slides onto the hot stamping inclined surface. Thereafter, the rotary motor drives the fan-shaped hot stamping block to rotate so as to hold the flat workpiece against the hot gold foil belt to perform the hot stamping operation.

[0007] That is to say, the hot stamping machine disclosed in the prior art mainly uses a suction cup conveying mechanism as the turnover conveying mechanism of the paper box; and the suction cup conveying mechanism usually requires that the surface of the adsorbed object must be smooth, flat and not easy to leak to ensure a good adsorption effect; and for objects with rough, uneven or easily deformed surfaces, the adsorption effect of the suction cup may be affected, resulting in unstable or failed transmission. In current production practice, it can be seen that in order to enhance the structural rigidity of the paper box, the current paper box is mostly made of corrugated paper and other materials, and its surface usually does not meet the requirements of a smooth plane that can be adsorbed by the suction cup; and the surface of the paper box processed by hot stamping usually has a concave and convex shape; in order to avoid the concave and convex shape affecting the adsorption effect of the suction cup, when designing the hot stamping on the surface of the paper box, it is necessary to specifically avoid the hot stamping position from the working area of ​​the suction cup. Moreover, the suction cup conveying mechanism mainly relies on the air pressure difference to achieve adsorption and release of objects. Therefore, the stability of air pressure is crucial to the performance of the suction cup conveying mechanism. If the air pressure fluctuates greatly or is unstable, it may affect the adsorption force and transmission accuracy of the suction cup; therefore, it is also necessary to connect the pipeline to an air pressure source, such as an air pump, to achieve air pressure transmission and control. This increases the complexity of the system and may affect the overall performance and reliability of the system. At the same time, the pipeline layout and control system design also need to consider a variety of factors, such as space limitations, ease of operation, etc. Summary of the invention
