Description

Technical Field

[0001] The utility model relates to the technical field of label processing equipment, in particular to a rotary disc type label pressing machine. Background Art

[0002] Thermal transfer is a widely used printing process, which is generally divided into two parts: transfer film printing and transfer processing. Transfer film printing refers to pre-printing the icon on the film surface, and transfer processing refers to transferring the icon on the transfer film to the carrier surface through a one-time processing (heating and pressurization) of a thermal transfer machine. After molding, the ink layer is integrated with the carrier surface.

[0003] In the manufacturing process of medium-sized products such as insoles, it is often necessary to print small trademark logos through thermal transfer, which is also called "pressing labels". At present, semi-automatic processing is mainly adopted, that is, manually putting insoles and other products and labels into the hot pressing station, and then controlling the hot pressing punch to perform hot pressing treatment on them. After hot pressing, the material is manually taken out and the next action is repeated. In actual operation, in order to improve work efficiency, the stamping action of the hot pressing punch is often set to automatically repeat up and down activities, and manual material placement and material taking need to adapt to its stamping rhythm. In order to facilitate operation, this method is generally set on the workbench on the front of the equipment in an open state, which leads to a high safety hazard. After a long period of high-intensity operation, it is easy to get hands pinched and burned due to operating errors, or the product is not placed in place to cause defective products.

After a long period of high-intensity operation, the operator's hands are easily pinched and burned due to operational errors, or the product is not placed in place, resulting in defective products.

[0032] In this embodiment, the rotary disc type labeling machine specifically includes a frame 100 , a hot pressing device 300 and a feeding device 400 .

[0033] Among them, the frame 100, as the supporting structure of the entire equipment, is usually welded with high-strength steel and has good stability and load-bearing capacity. A horizontal workbench 110 is provided on the frame 100 to facilitate the processing of the parts to be pressed (insoles and other products) by the operators. A horizontal turntable 200 is provided on the workbench 110. A step-type rotary drive mechanism (stepper motor) is connected to the bottom of the turntable 200. The rotation center line of the turntable 200 is vertically set. The turntable 200 is provided with 4 tooling positions for placing the parts to be pressed. The 4 tooling positions are centrally symmetrical with respect to the rotation center line of the turntable 200. In order to enable the parts to be pressed to be accurately placed on the tooling position, each tooling position is provided with a cross mark line as a positioning structure. In other embodiments, corresponding limit structures or tooling seats can also be configured.

Specifically, a mounting through hole is arranged at the horizontal section at the bottom of the side baffle, and a corresponding strip hole is arranged at the bottom of the movable groove 421. The side baffle 430 is connected and fixed to the feeding tray 420 by bolts. This design facilitates the adjustment of the position of the side baffle 430 to adapt to labels of different sizes and improves the versatility of the equipment. The lifting drive is specifically a lifting motor 441, which is arranged at the bottom of the mounting plate 410. The transmission output end of the lifting motor 441 is vertically connected to a push rod 440, which can extend to the bottom of the feeding trough inside the side baffle 430, and is used to lift the label at a threshold speed to ensure that the label can move upward stably and orderly, waiting to be adsorbed and transported.
