Description

Technical Field

[0001] This invention belongs to the field of hot stamping dental strips, and in particular relates to a dental strip with a blower function and its working method. Background Technology

[0002] In existing hot stamping equipment, especially high-speed equipment, a blower mechanism is typically used to better achieve the flattening and peeling of gold foil (electroplated aluminum) from paper. When the gripper bar reaches the working area and completes the hot stamping, the blower mechanism blows air into the gap between the paper and the gold foil, achieving the flattening and peeling effect. The closer the airflow from the nozzle of the blowing mechanism is to the underside of the gold foil, the better the flattening and peeling effect, as the airflow is blown out from the gap between the paper and the gold foil at approximately the same level as the paper. The nozzle blows out pressurized air.

[0003] In existing hot stamping equipment, the gripper structure lacks a blowing function; it only clamps and releases the paper. A separate blower mechanism is required to work in conjunction with the gripper, with the blower nozzle positioned as close as possible to the gold foil to complete the blowing action. The interaction and coordinated movement of the blower mechanism and the gripper require controlling both the movement of the gripper and the blower mechanism, making the control method quite complex and placing very high demands on the overall mechanism. Summary of the Invention

[0004] In view of this, the present invention aims to propose a working method for a dental rack with a blowing function, so as to solve the problems of existing technologies where the dental rack and the blowing mechanism need to be equipped separately, the control method is complicated, the overall machine requirements are high, and the cost is high.

[0005] To achieve the above objectives, the technical solution of the present invention is implemented as follows: A method for operating a gripper bar with a blowing function: when the gripper bar carries the paper through the hot stamping area, a moving platform that moves relative to it can lift the gripper bar in conjunction, so that the gripper bar approaches and connects to an air injection component. The air injection component can connect and blow air into the peeling gap through the air holes on the gripper bar, thereby peeling the paper and hot stamping foil apart by blowing air.

[0006] Another objective of this invention is to provide a tooth bar with a blowing function to solve the problem that the tooth bar in the existing equipment does not have an air outlet function and the overall structure is complicated.

[0007] To achieve the above objectives, the technical solution of the present invention is implemented as follows: A gripper bar with a blowing function includes a gripper bar body, which is capable of holding paper into or removing it from the hot stamping area of ​​a hot stamping equipment. The main body of the tooth bar is equipped with air blowing holes, which can blow out airflow. The airflow blown out by the air blowing holes is used to peel the paper and hot foil of the hot foil stamping. When the paper is hot stamped, the main body of the tooth bar can approach and connect to the output end of the air injection component through the power component, so that the air injection component can inject compressed air into the air blowing hole. The air injection component does not interfere with the movement of the tooth row body.

[0008] Furthermore, the main body of the tooth rack is provided with several lower tooth plates, which do not interfere with each other. Each lower tooth plate is provided with an upper tooth plate above it. Each upper tooth plate is fixedly sleeved to the tooth opening shaft. The tooth opening shaft is rotatably sleeved to the main body of the tooth rack. The tooth opening shaft is used to drive the upper and lower tooth plates to open or close relative to each other. The relatively closed upper and lower tooth plates are used to clamp the paper into or out of the hot stamping area of ​​the hot stamping equipment.

[0009] Furthermore, a plurality of air blowing holes are provided on one side of the tooth bar body; Furthermore, the air outlet of each air hole is located on one side of the lower dental plate, and the horizontal position of the air outlet is located between the upper and lower dental plates.

[0010] Furthermore, the main body of the tooth rack is provided with an air chamber, and each air blowing hole can be connected to the air chamber. The main body of the tooth rack is provided with a vent hole, which can be connected to the air injection component. The air injection component is connected to each air blowing hole in sequence through the vent hole and the air chamber.

[0011] Furthermore, the tooth bar body is provided with multiple vent holes, and each vent hole can be connected to an air injection component, and each vent hole is connected to an air blowing hole.

[0012] Furthermore, the tooth rack body is provided with multiple air chambers and multiple air vents. Each air chamber is connected to multiple air blowing holes, and each air vent is connected to an air injection component. The air injection component is connected to multiple air blowing holes in sequence through an air vent and an air chamber.

[0013] Furthermore, the air injection assembly includes an air guide tube, which is installed on a bracket and the bracket is fixedly connected to a fixed position. The air guide tube is connected to an external air injection device, the tooth bar body can be close to the air guide tube, and the air blowing hole is connected to the air guide tube.

[0014] Furthermore, an air guide nozzle is provided at one end of the air guide tube, which is used for the air guide tube to flexibly contact the tooth rack body.

[0015] Furthermore, the air nozzle is made of an elastic material.

[0016] Furthermore, the air nozzle is made of any one of rubber, engineering plastic, or high-density foam.

[0017] Furthermore, a first spring is provided around the air duct, and a sliding hole is provided on the bracket, allowing the air duct to slide within the sliding hole. The two ends of the first spring are respectively fixedly connected to the bracket and the air duct.

[0018] Furthermore, an upper clamping platform and a lower clamping platform are respectively fitted around the outer periphery of the air guide tube, and the upper clamping platform and the lower clamping platform are respectively located on both sides of the bracket. The two ends of the first spring are respectively fixedly connected to one side of the bracket and the lower clamping platform.

[0019] Furthermore, a slide bar is provided on one side of the hot stamping equipment, and a power component is provided at one end of the slide bar. The other end of the slide bar is used to support the main body of the tooth bar to move closer to or away from the output end of the air injection component, and the movement of the slide bar supporting the main body of the tooth bar is synchronized with the movement of the moving platform of the hot stamping equipment.

[0020] Compared with the prior art, the dental rack with air blowing function described in this invention has the following advantages: (1) The tooth bar with blowing function described in this invention, in addition to having normal paper clamping and paper feeding functions, has an air chamber in the main body of the tooth bar. The air can enter through the air hole above the chamber and exit through the air hole after passing through the chamber. The airflow blows towards the peeling gap between the hot stamping foil and the paper to complete the blowing and peeling action. While driving the paper, it also has the function of blowing and peeling. This reduces the number of parts in the equipment and the control structure between the cooperating parts, thus reducing the equipment cost. During installation and debugging, it reduces the restriction on the installation position of the blowing structure. When assembled on the tooth bar, it can better approach the peeling gap, so that the paper and the gold foil can be blown and peeled apart, ensuring the peeling quality.

[0021] (2) The tooth bar with blowing function described in this invention has an air guide tube in the air injection component that can move axially and extend and retract. A first spring is provided on the periphery of the air guide tube to provide elastic force downward. When the tooth bar is lifted, the air guide nozzle can always be attached to the tooth bar body. When the tooth bar is lowered, the lower limit position of the air guide tube does not interfere with the tooth bar moving away from the hot stamping equipment. Attached Figure Description

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] A working method of a gripper bar with a blowing function: When the gripper bar carries the paper 9 through the hot stamping area, the relatively moving platform can lift the gripper bar in conjunction, so that the gripper bar is close to and connected to the air injection component 5. The air injection component 5 can connect and blow air into the peeling gap through the air blowing holes 11 on the gripper bar. The paper 9 and the hot stamping foil are peeled off by blowing air. With this method, after the hot stamping function is completed, the paper 9 and the hot stamping foil need to be peeled off with high-pressure airflow. By using a gripper bar with a blowing function, the high-pressure airflow blown out from the front end of the gripper bar can separate the paper 9 and the hot stamping foil, which can save the need for a separate air blowing device, thereby reducing the cost of the machine.

[0029] To achieve the above working method, such as Figures 1-5 As shown, a gripper bar with a blowing function is provided, including a gripper bar body 1, which can clamp paper 9 into or out of the hot stamping area of ​​the hot stamping equipment; the gripper bar body 1 is provided with an air blowing hole 11, which can blow out airflow to complete the peeling of the paper 9 from the hot stamping foil 8; when the paper 9 is hot stamped, the gripper bar body 1 can approach and connect to the output end of the air injection component 5, so that the air injection component 5 can inject compressed airflow into the air blowing hole 11; the air injection component 5 does not interfere with the movement of the gripper bar body 1, and when the hot stamping equipment is working normally, the air guide nozzle 52 of the air injection component 5 is in contact with the gripper bar; the pressurized airflow will be filled into the gripper bar exhaust chamber 12 through the air injection component 5 and blown out from the air blowing hole 11 of the gripper bar; the pressurized airflow is blown to the entire hot stamping area to achieve the flattening and peeling of the paper 9 from the hot stamping foil.

[0030] like Figure 2 As shown, a plurality of lower gripper plates 2 are provided on the gripper body 1. The plurality of lower gripper plates 2 do not interfere with each other. An upper gripper plate 3 is provided above each lower gripper plate 2. Each upper gripper plate 3 is fixedly sleeved to the opening shaft 4. The outer periphery of the opening shaft 4 is rotatably sleeved to the gripper body 1. The opening shaft 4 is used to drive the upper gripper plate 3 and the lower gripper plate 2 to open or close relative to each other. The relatively closed upper gripper plate 3 and the lower gripper plate 2 are used to clamp the paper 9 into or out of the hot stamping area of ​​the hot stamping equipment. The above-mentioned movement method of driving the upper gripper plate 3 and the lower gripper plate 2 to open or close relative to each other through the opening shaft 4 is the prior art.

[0031] In practice, to ensure uniform airflow into the peeling gap from the air holes 11 on one side of the tooth strip body 1, multiple air holes 11 are provided on one side of the tooth strip body 1. These air holes 11 are horizontally distributed, with the outlet of each air hole 11 located on one side of the lower tooth plate 2. The horizontal position of the outlet is between the upper tooth plate 3 and the lower tooth plate 2. The air holes 11 can blow out pressurized airflow, and the airflow direction is kept as horizontal as possible to the paper 9. The airflow blown into the space between the paper 9 and the gold foil forms a pressurized airflow layer, completing the peeling action based on aerodynamic principles. Each air hole 11 can be connected to the air injection component 5, and there are various embodiments where the air holes 11 are connected to the air injection component 5.

[0032] First Embodiment The main body 1 of the tooth rack is provided with an air chamber 12, and each air blowing hole 11 is connected to the air chamber 12. The main body 1 of the tooth rack is provided with a vent hole 13, which can be connected to the air injection component 5. The air injection component 5 is connected to each air blowing hole 11 through the vent hole 13 and the air chamber 12 in sequence.

[0033] Second Embodiment The main body 1 of the tooth rack is provided with multiple air holes 13, and each air hole 13 can be connected to the air injection component 5, and each air hole 13 is connected to an air blowing hole 11.

[0034] Third Embodiment The main body 1 of the dental rack is provided with multiple air chambers 12 and multiple air holes 13. Each air chamber 12 is connected to multiple air blowing holes 11. Each air hole 13 can be connected to the air injection component 5. The air injection component 5 is connected to multiple air blowing holes 11 in sequence through one air hole 13 and one air chamber 12.

[0035] 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. The air guide tube 51 is installed on a bracket, and the bracket is fixedly connected to a fixed position. The air guide tube 51 is connected to an external air injection device. The toothed plate body 1 can approach and connect to one end of the air guide tube 51. An air nozzle 52 is provided at one end of the air guide tube 51. The air nozzle 52 is used for the air guide tube 51 to flexibly contact the toothed plate body 1. The air nozzle 52 is made of an elastic material, such as rubber, engineering plastic, or high-density foam.

[0036] The air tube 51 can extend and retract freely within the bracket. In order to enable the air tube 51 to elastically return to its original position, a first spring 53 is provided around the air tube 51, and the bracket is provided with a sliding hole. The outer periphery of the air tube 51 can slide within the sliding hole. The two ends of the first spring 53 are fixedly connected to the bracket and the outer periphery of the air tube 51, respectively. The elastic force of the first spring 53 acts directly on the axial direction of the air tube 51. The first spring 53 is used to control the extension and retraction of the air nozzle 52 to fit the toothed row that moves up and down.

[0037] During hot stamping, as the horizontal movement of the gripper bar transitions to its upward movement, the vent 13 at the upper end of the gripper bar slowly approaches the air guide nozzle 52. The vent 13 and the air guide nozzle 52 are basically aligned and fit together from bottom to top. When the air guide nozzle 52 is in contact with the gripper bar, during the up-and-down movement of the gripper bar, the air guide nozzle 52 will fit tightly against the vent 13.

[0038] During the transition from downward to horizontal movement of the tooth rack, the tooth rack slowly detaches from the air guide nozzle 52, and the tooth rack vent 13 detaches from the air guide nozzle 52 of the air injection component 5. During the horizontal movement of the tooth rack, the air guide nozzle 52 maintains a certain distance from the lower end face of the tooth rack vent 13, so as not to affect the movement of the tooth rack.

[0039] The air guide tube 51 is fitted with an upper locking platform 54 and a lower locking platform 55, which are located on both sides of the support. The two ends of the first spring 53 are fixedly connected to one side of the support and the lower locking platform 55, respectively. The upper locking platform 54 and the lower locking platform 55 are the upper and lower limits of the vertical axial movement of the air guide tube 51, preventing the air guide tube 51 from leaving the control range of the support.

[0040] A slide bar 56 is provided on one side of the hot stamping equipment, and a power component is provided at one end of the slide bar 56. The other end of the slide bar 56 is used to support the gripper body 1 to move closer to or away from the output end of the air injection component 5. The movement of the slide bar 56 supporting the gripper body 1 is synchronized with the movement of the moving platform of the hot stamping equipment. The power component 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 equipment also includes an upper platform 6, which is a stationary platform. The upper platform 6 and the lower platform 7 move relative to each other to hot stamp the paper 9, and the hot stamping area is located between the upper platform 6 and the lower platform 7.

[0041] The working process of using a toothed roller with a blower function in conjunction with a hot stamping device: Paper 9 moves horizontally from the conveyor towards the hot stamping equipment. As paper 9 approaches the equipment, it is gripped by the upper gripper 3 and lower gripper 2 of the gripper bar and moves along with it. The gripper bars are evenly distributed at equal intervals around the circumference of the chain. Two chains of equal length and symmetrically connect the gripper bars, forming a closed loop. The two chains rotate around the hot stamping equipment on both sides. The gripper bars rotate intermittently, and their intermittent movement corresponds to the opening and closing movement of the moving platform.

[0042] When the upper platform 6 and the lower platform 7 are opened, the paper 9 is held in the gripper bar and passes along the chain track in the space between the upper platform 6 and the lower platform 7. The gripper bar will move to the working position and stay briefly. When the upper and lower platforms are closed, the gripper bar moves upward together with the moving platform (lower platform 7) and fits against the air guide nozzle 52.

[0043] When the upper and lower platforms are closed, hot stamping foil is applied to the paper 9, completing the hot stamping process. During the hot stamping process, the gripper bar is stopped, and the upper platform 6 is fixed on the machine and does not move.

[0044] As the upper and lower platforms open again, the gas delivered by the tooth rack through the air guide nozzle 52 begins to blow air. As the moving platform moves downward, it separates from the air guide nozzle 52 during the movement. When it separates, the air guide nozzle 52 stops delivering air, and the tooth rack stops moving at the lower dead point.

[0045] When the upper and lower platforms open again, the gripper bar holding the paper 9, which has completed the hot stamping action, flows to the next process. The next gripper bar on the closed-loop chain holds the new paper 9 and passes between the upper and lower platforms to prepare for the hot stamping action. When the upper and lower platforms close, the new paper 9 is hot stamped with the pattern. This cycle repeats, with the platforms opening and closing, the gripper bar holding the paper 9 entering, and then holding the paper 9 leaving.

[0046] The working process of airflow outlet of tooth rack body 1: The opening and closing of the upper and lower jaw plates are controlled by the small-angle reciprocating rotation of the jaw opening shaft 4. The paper 9 is sandwiched between the lower jaw plate 2 and the upper jaw plate 3. The jaw plate body 1 has a closed air chamber 12. High-pressure airflow can enter the air chamber 12 from the vent 13 at the upper end of the jaw plate body 1 and blow out the high-pressure airflow from the blow hole 11. The airflow is blown out forward without being blocked by any parts.

[0047] like Figure 4 , Figure 5 As shown, after hot stamping is completed, the moving platform moves downward, the distance between the upper platform 6 and the moving platform gradually increases, and the slide bar also falls a certain distance; at the same time as the slide bar falls, the gripper bar supported by the slide bar also falls; the gripper bar maintains the paper clamping state, and the paper 9 falls along with the gripper bar as it falls; during the process of the gripper bar falling, the air guide pipe 51 is subjected to the combined action of the first spring 53 of the air injection component 5 and the gripper bar, and the air guide nozzle 52 always sticks to the gripper bar and extends downward.

[0048] As the gripper bar descends, the first spring 53 is releasing its elastic force. The support is fixed to the machine, and the air guide tube 51 extends downwards under the elastic force. High-pressure airflow enters from the upper part of the air guide tube 51 and exits from the air nozzle 52 at the lower part of the air guide tube 51. The on / off state and frequency control of the high-pressure airflow are controlled by a solenoid valve, ensuring a more stable and efficient flow of air into the gripper bar cavity. After the moving platform descends a short distance, creating a gap between the paper 9 and the hot stamping foil 8, the air guide tube 51 delivers pressurized airflow into the gripper bar and blows the airflow into the gap between the paper 9 and the hot stamping foil 8 through the air outlet 11 of the gripper bar. The gap mentioned in the text is one that allows airflow to enter, achieving the ideal peeling gap by blowing it flat.

[0049] The up-and-down movement of the slide bar must be synchronized with the moving platform. The power source for the up-and-down movement of the slide bar is not limited. It can be provided by the moving platform driving the cam or connecting rod, or by a servo motor synchronized with the moving platform, as long as the function can be achieved.

[0050] When the moving platform maintains the lower stop position, the upper platform 6 and the moving platform maintain the maximum separation distance; the slide bar maintains the low position; the air guide tube 51 is kept in the low position on the bracket, the first spring 53 is stretched to the maximum and is in a relatively relaxed state; under the traction of the chain, the toothed bar clamps the paper 9 and moves close to the lower platform 7 toward the slide bar.

[0051] As the moving platform rises from its lower limit, it moves upwards; the slide bar follows the moving platform synchronously, lifting the toothed bar upwards; the lifted toothed bar moves upwards and gradually contacts the air inlet 52 of the air injection assembly 5. The air inlet tube 51 remains in its low extension position on the support and gradually contracts upwards, at which time the first spring 53 is gradually compressed from its maximum extension position.

[0052] 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 principles of the present invention should be included within the protection scope of the present invention.
