When the teeth row runs to the working area and completes the hot stamping, the blower mechanism blows air into the gap between the paper and the gold foil to achieve the flattening and peeling of the gold foil and paper. The closer the airflow position of the blowing nozzle of the blowing mechanism is to the lower surface of the gold foil, the wind that is nearly horizontal with the paper is blown out from the gap between the paper and the gold foil, and the flattening and peeling effect is better. The blowing nozzle blows out pressurized airflow.

[0041] A working method of a tooth bar with a blowing function: when the tooth bar drives the paper 9 to pass through the hot stamping area, the relatively moving dynamic platform can lift the tooth bar in a linked manner, so that the tooth bar is close to and connected to the air injection component 5, and the air injection component 5 can be connected and blow air to the peeling gap through the blowing holes 11 on the tooth bar, and the paper 9 and the hot stamping foil are peeled off by blowing air. Through this method, after the hot stamping function is completed, according to the characteristics that the paper 9 and the hot stamping foil need to be peeled off with high-pressure airflow, a tooth bar with a blowing function is used, and high-pressure airflow is blown out through the front end of the tooth bar to separate the paper 9 and the hot stamping foil, which can save a separate blowing device, thereby reducing the cost of the machine.

[0042] To implement the above working method, Figure 1-Figure 5 As shown, a tooth bar with a blowing function is provided, including a tooth bar main body 1, which can clamp the paper 9 to enter or move out of the hot stamping area of ​​the hot stamping equipment; a blowing hole 11 is provided on the tooth bar main body 1, and the blowing hole 11 can blow out airflow, and the airflow blown out by the blowing hole 11 is used to complete the peeling of the hot stamped paper 9 and the hot stamping foil 8; when the paper 9 is hot stamped, the tooth bar main body 1 can be close to and connected to the output end of the air injection component 5, so that the air injection component 5 can inject compressed airflow into the blowing hole 11; the air injection component 5 does not interfere with the movement of the tooth bar main body 1, and when the hot stamping equipment is working normally, the air guide nozzle 52 of the air injection component 5 and the tooth bar are in contact; the pressurized airflow will be filled into the tooth exhaust cavity 12 through the air injection component 5, and blown out from the blowing hole 11 of the tooth bar; the pressurized airflow is blown to the entire hot stamping format to achieve the flattening and peeling of the paper 9 and the hot stamping foil.

[0043] like Figure 2 As shown, a plurality of lower tooth plates 2 are arranged on the tooth bar main body 1, and the plurality of lower tooth plates 2 do not interfere with each other. An upper tooth plate 3 is correspondingly arranged above each lower tooth plate 2, and each upper tooth plate 3 is fixedly sleeved on the tooth opening shaft 4. The outer periphery of the tooth opening shaft 4 is rotatably sleeved on the tooth bar main body 1, and the tooth opening shaft 4 is used to drive the upper tooth plate 3 and the lower tooth plate 2 to open or close relatively. The relatively closed upper tooth plate 3 and the lower tooth plate 2 are used to clamp the paper 9 to enter or move out of the hot stamping area of ​​the hot stamping equipment, and the above-mentioned movement mode of driving the upper tooth plate 3 and the lower tooth plate 2 to open or close relatively by the tooth opening shaft 4 is the prior art.

[0044] During implementation, in order to make the airflow blown into the stripping gap from the air holes 11 on one side of the tooth bar body 1 uniform, a plurality of air holes 11 are provided on one side of the tooth bar body 1, and the plurality of air holes 11 are horizontally distributed, and the air outlet end of each air hole 11 is located on one side of the lower tooth piece 2, and the horizontal position of the air outlet end is located between the upper tooth piece 3 and the lower tooth piece 2, and the air hole 11 can blow out pressurized airflow, and the airflow direction is kept as horizontal as possible with the paper 9. The airflow is blown into the space between the paper 9 and the gold foil to form a pressurized airflow layer, and the stripping action is completed according to the aerodynamic principle, and each air hole 11 can be connected to the air injection component 5, and there are multiple embodiments in which the air hole 11 is connected to the air injection component 5.

[0045] First embodiment

[0046] An air cavity 12 is provided in the tooth bar body 1, and each blowing hole 11 is connected to the air cavity 12. An air vent 13 is provided on the tooth bar body 1, and the air vent 13 can be connected to the air injection component 5, and the air injection component 5 is connected to each blowing hole 11 through the air vent 13 and the air cavity 12 in turn.

[0047] Second embodiment

[0048] A plurality of vent holes 13 are provided on the gripper bar body 1 , and each vent hole 13 can be connected to the air injection assembly 5 , and each vent hole 13 is correspondingly connected to one blowing hole 11 .

[0049] Third embodiment

[0050] A plurality of air cavities 12 are provided in the tooth bar body 1, and a plurality of ventilation holes 13 are provided on the tooth bar body 1, each air cavity 12 is connected to a plurality of corresponding blowing holes 11, each ventilation hole 13 can be connected to the gas injection component 5, and the gas injection component 5 is connected to the plurality of blowing holes 11 through a ventilation hole 13 and an air cavity 12 in sequence.

[0051] like Figure 3 As shown, the air injection assembly 5 includes an air guide tube 51, which is perpendicular to the paper 9 in the hot stamping area 10, and is installed on a bracket, and the bracket is fixedly connected to a fixed position, and the air guide tube 51 is connected to an external air injection device, and the tooth bar body 1 can be close to and connected to one end of the air guide tube 51, and an air guide nozzle 52 is set at one end of the air guide tube 51, and the air guide nozzle 52 is used for the air guide tube 51 to flexibly contact the tooth bar body 1, and the material of the air guide nozzle 52 is an elastic material, and the air guide nozzle 52 is any one of rubber, engineering plastics or high-density foam.

[0052] The air guide tube 51 can be extended and retracted freely up and down in the bracket. In order to realize the elastic reset of the air guide tube 51, a first spring 53 is arranged on the periphery of the air guide tube 51, and a sliding hole is provided on the bracket. The periphery of the air guide tube 51 can slide in the sliding hole. The two ends of the first spring 53 are respectively fixedly connected to the bracket and the periphery of the air guide tube 51. The elastic force of the first spring 53 directly acts on the axial direction of the air guide tube 51. The first spring 53 is used to control the extension and retraction of the air guide nozzle 52 to fit the tooth row moving up and down.

[0053] During hot stamping, the horizontal movement of the tooth bar transitions to the upward movement process, and the air vent 13 at the upper end of the tooth bar slowly approaches the air nozzle 52, and the air vent 13 of the tooth bar is basically aligned with the air nozzle 52, and fits together from bottom to top; when the air nozzle 52 is fitted, the air nozzle 52 will fit tightly with the tooth bar on the air vent 13 during the up and down movement of the tooth bar.

[0054] During the transition from the downward movement of the tooth bar to the horizontal movement, the tooth bar slowly separates from the air guide nozzle 52, and the tooth bar air vent 13 separates from the air guide nozzle 52 of the gas injection assembly 5; during the horizontal movement of the tooth bar, the air guide nozzle 52 maintains a certain distance from the lower end surface of the air vent 13 of the tooth bar and does not affect the movement of the tooth bar.

[0055] An upper clamping platform 54 and a lower clamping platform 55 are respectively mounted on the periphery of the air guide tube 51, and the upper clamping platform 54 and the lower clamping platform 55 are respectively located on both sides of the bracket, and both ends of the first spring 53 are respectively fixedly connected to one side of the bracket and the lower clamping platform 55, and the upper clamping platform 54 and the lower clamping platform 55 are the upper limit and lower limit of the up and down axial movement of the air guide tube 51, preventing the air guide tube 51 from escaping from the control range of the bracket.

[0056] A slide bar 56 is arranged on one side of the hot stamping device, and a power assembly is arranged on one end of the slide bar 56. The other end of the slide bar 56 is used to support the tooth bar body 1 close to or away from the output end of the gas injection assembly 5, and the movement of the slide bar 56 supporting the tooth bar body 1 is synchronized with the movement of the moving platform of the hot stamping device. The power assembly is a servo motor or is linked with the moving platform through a linkage structure. The moving platform is the lower platform 7. The hot stamping device also includes an upper platform 6, and the upper platform 6 is a static platform. The upper platform 6 and the lower platform 7 move relative to each other for hot stamping the paper 9, and the hot stamping area is located between the upper platform 6 and the lower platform 7.

[0057] The working process of the tooth bar with blowing function and hot stamping equipment:

[0058] The paper 9 moves horizontally from the conveyor to the hot stamping equipment. When the paper 9 is close to the hot stamping equipment, the paper 9 is clamped by the upper teeth 3 and the lower teeth 2 of the teeth bar and moves with the teeth bar. The teeth bar is evenly distributed on the chain at equal distances. The two chains are equal in length and symmetrically connect the teeth bar in series to form a closed loop. The two chains rotate in circles on both sides of the hot stamping equipment. The teeth bar operates intermittently, and the gap movement of the teeth bar and the opening and closing movement of the moving platform are in a mutually echoing relationship.

[0059] When the upper platform 6 and the lower platform 7 are opened, the tooth bar clamps the paper 9 and passes along the chain track in the space between the upper platform 6 and the lower platform 7, and the tooth bar moves to the working position and stays briefly; when the upper and lower platforms 7 are closed, the tooth bar moves upward with the moving platform (lower platform 7) and fits with the air guide nozzle 52.

[0060] When the upper and lower platforms 7 are closed, the hot stamping foil is stamped onto the paper 9 to complete the stamping operation. During the stamping process, the teeth row is stopped and the upper platform 6 is fixed on the machine and does not move.

[0061] When the upper and lower platforms 7 are opened again, the gripper bar starts to blow air through the gas delivered by the air nozzle 52, and as the movable platform moves downward, it separates from the air nozzle 52 during the movement. When separated, the air nozzle 52 stops delivering air, and the gripper bar moves to the lower dead point and stops.

[0062] When the upper and lower platforms 7 are opened again, the gripper bar that has completed the hot stamping action clamps the paper 9 and flows to the next process. The next gripper bar on the closed-loop chain clamps the new paper 9 and passes between the upper and lower platforms 7 to prepare for the hot stamping action. When the upper and lower platforms 7 are closed, the new paper 9 is hot stamped. This cycle repeats, the platforms open and close, the gripper bar clamps the paper 9 to enter, and then clamps the paper 9 to leave.

[0063] Working process of the tooth bar body 1 to derive air flow:

[0064] The opening and closing of the upper and lower teeth 2 are controlled by the small angle reciprocating rotation of the tooth opening shaft 4. The paper 9 is sandwiched between the lower tooth 2 and the upper tooth 3. A closed air cavity 12 is provided in the tooth bar body 1. High-pressure airflow can enter the air cavity 12 from the vent hole 13 at the upper end of the tooth bar body 1, and blow out the high-pressure airflow from the blowing hole 11. The front of the airflow is not blocked by any parts.

[0065] like Figure 4 , Figure 5As shown, after the hot stamping is completed, the movable platform 1 is in a downward movement, the distance between the upper platform 6 and the movable platform gradually increases, and the slider also falls a certain distance; while the slider falls, the tooth bar 4 held up by the slider also falls; the tooth bar remains in a paper clamping state, and the paper 9 falls with the tooth bar as it falls; during the descent of the tooth bar, the air guide tube 51 is acted upon by the first spring 53 of the air injection assembly 5 and the tooth bar, and the air guide nozzle 52 always sticks to the tooth bar and extends downward.

[0066] When the tooth bar is moving downward, the first spring 53 is releasing its elastic force; the bracket is fixed to the machine, and the air duct 51 is extended downward by the elastic force, and the high-pressure airflow enters from the upper part of the air duct 51, and is ejected from the air nozzle 52 at the lower part of the air duct 51. The on-off and frequency control of the high-pressure airflow is controlled by the solenoid valve, which can ensure that the high-pressure airflow enters the tooth bar cavity more stably and efficiently. After the moving platform falls a short distance, there is a gap between the paper 9 and the hot stamping foil 8, and the air duct 51 sends the pressurized airflow into the tooth bar, and blows the airflow into the gap between the paper 9 and the hot stamping foil 8 from the blowing hole 11 of the tooth bar. The gap mentioned in the text is the one that can blow the airflow in, and can achieve the most ideal peeling gap for flat peeling.

[0067] The up and down movement of the slider must be synchronized with the moving platform. The power source of the up and down movement of the slider is not limited. It can be provided by a cam or connecting rod driven by the moving platform, or it can be provided by a servo motor synchronized with the moving platform, as long as the function can be achieved.

[0068] When the movable platform maintains the lower dead center position, the upper platform 6 and the movable platform maintain the maximum separation distance; the slider maintains the low point position; the air guide tube 51 on the bracket remains at a low position, the first spring 53 is stretched to the maximum and is in a relatively relaxed state; the tooth row, under the traction of the chain, clamps the paper 9 and moves close to the lower platform 7 toward the slider.

[0069] When the movable platform rises from the lower dead point, the movable platform moves from bottom to top; the slider follows the movable platform to synchronously lift the gripper row and move upward; the lifted gripper row moves upward and gradually contacts the air guide nozzle 52 of the air injection assembly 5. The air guide tube 51 is kept at a low extension position on the bracket and gradually contracts upward, at which time the first spring 53 is gradually compressed from the maximum extension position.

[0070] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
