Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0032] The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "side", "top" and "bottom", are only for reference to the orientation of the drawings. The directional terms used are used to illustrate and understand the present invention, but not to limit the present invention.

[0033] In the figures, structurally similar elements are denoted by the same reference numerals.

[0034] Please refer to Figure 1 , Figure 2 In this embodiment, the rubber thread strip zipper hot stamping machine 10 includes a frame 20, a zipper guide mechanism 30, a hot stamping paper guide mechanism 40, a hot stamping mechanism 50, a power mechanism 60, a heating mechanism 70, a material receiving mechanism 80, a sensing mechanism 90, an idler mechanism 100 and a controller. The frame 20 is welded by a square tube, and doors are installed at the front and back of the frame 20, and an electric box is arranged inside the frame 20.

[0035] In this embodiment, please refer to Figure 1 The zipper guide mechanism 30 is arranged on the frame 20 and is used to convey the zipper. The zipper guide mechanism 30 includes a first support rod 31 and a plurality of first guide wheels 32. The plurality of first guide wheels 32 are arranged on the first support rod 31 in sequence and at intervals. The zipper passes through the plurality of first guide wheels 32 in a serpentine shape. The first guide wheels 32 are used to provide a guide for conveying the zipper and prevent swinging.

[0036] Please refer to Figure 1 The hot stamping paper guide mechanism 40 is arranged on the frame 20 and is located between the zipper guide mechanism 30 and the hot stamping mechanism 50, and is used to transport the hot stamping paper. The hot stamping paper guide mechanism 40 includes a second support rod 41 and a plurality of second guide wheels 42, which are arranged on the second support rod 41 in sequence and at intervals. The hot stamping paper passes through the second guide wheels 42, and the second guide wheels 42 are used to provide a guide for the transportation of the hot stamping paper to prevent swinging. In the figure, the zipper and the hot stamping paper are not drawn.

[0037] Please refer to Figure 1 The idler mechanism 100 is arranged below the zipper guide mechanism 30, and the idler mechanism 100 includes a movable wheel 101 and an idler wheel 102. After the zipper comes out of the zipper guide mechanism 30, the zipper passes between the movable wheel 101 and the idler wheel 102. The movable wheel 101 is pulled down by the tension spring to press the idler wheel 102. A first spring is pressed at one end of the idler wheel 102. The greater the pressure of the first spring, the greater the resistance of the idler wheel 102. As a result, the tension of the zipper is also greater, which can improve the work efficiency and the quality of hot stamping.

[0038] Please refer to Figure 3The heating mechanism 70 includes a blower 71, a heater, an air duct 72 and an oven 73. The blower 71 is arranged on the frame 20, and a feed port 731 is arranged on one side of the oven 73 close to the idler mechanism 100, so that the zipper can enter the oven 73 from the idler mechanism 100. A plurality of third guide wheels 74 are arranged inside the oven 73, and the third guide wheels 74 are arranged in two rows for guiding the zipper. The zipper passes through the two rows of third guide wheels 74 in sequence, so that the zipper can be evenly heated in the oven 73. One end of the air duct 72 is connected to the blower 71, and the other end of the air duct 72 is provided with two air outlets, one of which is connected to the oven 73, and the other air outlet is located above the positioning wheel 53. The blower 71 sends air to the heater through the air duct 72, and the air is heated in the heater to form hot air, which is sent to the oven 73 and the bronzing wheel 52 through the air duct 72.

[0039] In this embodiment, the upper end of the oven 73 is provided with a discharge port 732, and the zipper is connected to the sensing mechanism 90 after coming out of the discharge port 732. Figure 4 The sensing mechanism 90 includes a sensing block 91, a guide seat 92, two guide rods 93, two springs 94 and a sensing probe 95. The guide seat 92 is arranged on the frame 20 and is located between the zipper guide mechanism 30 and the hot stamping mechanism 50. A guide groove 921 is vertically provided through the guide seat 92, and the zipper is located in the guide groove 921. The guide groove 921 is located on one side of the sensing block 91, which is convenient for installing the zipper and improving work efficiency. A card slot is provided on both side walls of the guide slot 921. The sensing block 91 is in a strip shape, and its two ends are respectively slidably arranged in the card slot. The length direction of the sensing block 91 is perpendicular to the length direction of the zipper, and the structure is compact and cost-saving. A groove 922 is also provided in the guide groove 921 of the guide seat 92, and the groove 922 is used for guiding the chain teeth. Both ends of the groove 922 are provided with an enlarged end, and the depth of the enlarged end is greater than the depth of the groove 922. There is a thickness change at the chain teeth of the zipper, and an enlarged end is provided to facilitate the entry of the chain teeth. The upper and lower ends of the side of the sensing block 91 close to the guide seat 92 are both provided with inclined surfaces. The thickness of the side where the sensing block 91 contacts the guide seat 92 is the smallest, which improves the efficiency of installation. It is also convenient to adapt to the thickness change between the fixed-size area and the chain tooth area, and facilitates the chain tooth area to enter between the sensing block 91 and the guide seat 92. A guide rod 93 is provided on both sides of the guide seat 92. One end of the guide rod 93 passes through the sensing block 91 and is connected to the guide seat 92, and the sensing block 91 is slidably connected to the guide rod 93. The other end of the guide rod 93 is provided with a spring 94, and the spring 94 is used to return the sensing block 91 to the fixed-size position, thereby improving work efficiency. The sensing block 91 is slidably connected to the guide seat 92, and the sensing probe 95 is fixedly set on the guide seat 92 to sense whether the sensing block 91 moves away from the guide seat 92.

[0040] The zipper includes a fixed-size area and a chain tooth area arranged along the length direction of the zipper. The fixed-size area of ​​the zipper indicates a place without teeth and does not require hot stamping. The chain tooth area of ​​the zipper has teeth and requires hot stamping. The thickness of the chain tooth area is greater than that of the fixed-size area. The sensing block 91 is slidably connected to the guide seat 92 to move between the fixed-size position and the chain tooth position. The fixed-size position is close to the guide seat 92 relative to the chain tooth position, and the zipper is passed between the sensing block 91 and the guide seat 92. The sensing probe 95 is fixedly disposed on the guide seat 92 to detect the position of the sensing block 91. When the fixed-size area is located between the sensing block 91 and the guide seat 92, the sensing block 91 is located at the fixed-size position, and when the chain tooth area is located between the sensing block 91 and the guide seat 92, the sensing block 91 is located at the chain tooth position.

[0041] The controller is electrically connected to the sensing probe 95 and the driving device 51, and is used to receive the signal of the sensing probe 95 and control the driving device 51 to drive the hot stamping wheel 52 to move. Among them, the sensing probe 95 can only sense whether the sensing block 91 is in the fixed size area or the chain tooth area. There is still a distance between the sensing block 91 and the positioning wheel 53, and this distance is fixed. The length of time to pass this distance can be determined according to the conveying speed of the zipper. Therefore, after the sensing probe 95 senses that the sensing block 91 is located at the chain tooth position, the time can be adjusted in the controller, and the delay can be set by the controller for a few seconds, and then the controller outputs a signal to control the driving device 51 to start. The controller uses PLC to communicate with the driving cylinder 512 and the sensing probe 95 respectively.

[0042] When the chain tooth area of ​​the zipper passes between the sensing block 91 and the guide seat 92, the chain tooth area pushes the sensing block 91 out and moves along one end of the guide rod 93 installed with the spring 94, and the spring 94 is compressed. When the fixed-size area of ​​the zipper passes between the sensing block 91 and the guide seat 92, the sensing block 91 is pushed to one side of the fixed seat 513 by the restoring force of the spring 94. During the movement of the sensing block 91, the sensing probe 95 can sense the sensing block 91 and transmit the signal to the PLC. The PLC transmits the signal to the solenoid valve through analysis. The solenoid valve receives the signal and opens or closes the air valve to realize the up and down movement of the driving cylinder 512 on the hot stamping mechanism 50.

[0043] In this embodiment, please refer to Figure 5 , Figure 6 The hot stamping mechanism 50 includes a driving device 51, a hot stamping wheel 52, a positioning wheel 53 and a first transmission shaft 54. The driving device 51 is connected to the hot stamping wheel 52, and the hot stamping wheel 52 and the positioning wheel 53 are arranged at an interval, and the zipper and the hot stamping paper are inserted between the hot stamping wheel 52 and the positioning wheel 53. The positioning wheel 53 is provided with a limiting groove 531, and the chain teeth of the zipper are located in the limiting groove 531 to prevent the zipper from shaking and shifting.

[0044] The driving device 51 includes a mounting seat 511, a driving cylinder 512 and a fixing seat 513. The mounting seat 511 is arranged on the frame 20, and the driving cylinder 512 is arranged above the mounting seat 511. The driving cylinder 512 drives the hot stamping wheel 52 to move up and down. A fixing groove 514 is arranged at one end of the fixing seat 513. The two sides and the upper end of the fixing groove 514 opposite to the hot stamping wheel 52 are open, and the groove width of the upper end of the fixing groove 514 is smaller than the groove width of the lower end of the fixing groove 514. The end of the output shaft of the driving cylinder 512 is clamped in the fixing groove 514. One end of the first transmission shaft 54 ​​passes through the fixing seat 513 and is fixedly connected to the hot stamping wheel 52, which is convenient for installation and removal and replacement and maintenance.

[0045] The driving cylinder 512 is connected to the hot stamping wheel 52, and is used to drive the hot stamping wheel 52 to move between the working position and the rest position. The working position is closer to the positioning wheel 53 relative to the rest position. When the chain tooth area is located between the hot stamping wheel 52 and the positioning wheel 53, the hot stamping wheel 52 is located at the working position, and the zipper and the hot stamping paper are attached and hot stamping is performed. When the fixed size area is located between the hot stamping wheel 52 and the positioning wheel 53, the hot stamping wheel 52 is located at the rest position, and the zipper and the hot stamping paper are separated.

[0046] In this embodiment, please refer to Figure 5 The power mechanism 60 includes a support seat 64, a motor, a second transmission shaft 61, a first gear 62 and a second gear 63. The second transmission shaft 61 is mounted on the support seat 64, and the output shaft of the motor is connected to the second transmission shaft 61. The motor is not shown in the figure. The second transmission shaft 61 is connected to the other end of the first transmission shaft 54 ​​through a belt to drive the hot stamping wheel 52 to rotate. The structure is compact and cost-saving. The first gear 62 is fixedly connected to the end of the second transmission shaft 61, and the second gear 63 is meshed with the first gear 62.

[0047] Please refer to Figure 5 The receiving mechanism 80 includes two pressing wheels 81, a third transmission shaft 82 and a receiving tray 83. One pressing wheel 81 is fixedly connected to the first gear 62, and the other pressing wheel 81 is fixedly connected to the second gear 63. The zipper after hot stamping is located between the two pressing wheels 81, which saves costs. The third transmission shaft 82 is connected to the fixed seat 513 through a fixed plate, one end of the third transmission shaft 82 is connected to the first transmission shaft 54 ​​through a belt, and the other end of the third transmission shaft 82 is connected to the receiving tray 83, which is used to collect the hot stamping paper after the hot stamping operation.

[0048] The zipper is sequentially passed through the first guide wheels 32, the movable wheel 101 and the idle wheel 102, passed through the feed port 731 of the oven 73, arranged on the third guide wheels 74 in sequence, and transported out from the discharge port 732 of the oven 73. Then, the zipper passes through the guide groove 921 between the fixed seat 513 and the induction block 91, and is guided to the positioning wheel 53. The hot stamping paper sequentially passes through the second guide wheels 42, and is then placed on the zipper of the positioning wheel 53. As the zipper moves, when the chain tooth area is transported between the induction block 91 and the fixed seat 513, the air duct 72 sends the heated air to the oven 73 and the hot stamping wheel 52. At the same time, the induction probe 95 can sense that the induction block 91 is located at the chain tooth position and transmit the signal to the controller. The controller transmits the signal to the solenoid valve after analyzing and delaying the preset time. The solenoid valve receives the signal, opens the air valve, drives the cylinder 512 to drive the hot stamping wheel 52 to move toward the positioning wheel 53 and perform hot stamping operations, and the pressing wheel 81 and the receiving tray 83 rotate synchronously to receive the material. When the fixed-size area is transported to between the induction block 91 and the fixed seat 513, the induction probe 95 can sense that the induction block 91 is located at the fixed-size position and transmit the signal to the controller. The controller transmits the signal to the solenoid valve through analysis. The solenoid valve receives the signal, closes the air valve, and drives the cylinder 512 to drive the hot stamping wheel 52 to return to the stop position. When applying the film, the hot stamping wheel 52 avoids the fixed-size area to prevent the hot stamping paper from pressing on the zipper tape and causing dirty tape.

[0049] In this embodiment, the present invention relates to a hot stamping machine for zippers with rubber teeth strips, which includes a frame, a hot stamping mechanism, a power mechanism, a heating mechanism, a sensing mechanism and a controller. The hot stamping mechanism includes a driving device, a hot stamping wheel and a positioning wheel. The hot stamping wheel and the positioning wheel are arranged at intervals, and the zipper and the hot stamping paper are arranged between the hot stamping wheel and the positioning wheel. The driving device is connected to the hot stamping wheel, and is used to drive the hot stamping wheel to move between a working position and a stop position. The working position is close to the positioning wheel relative to the stop position. When the chain tooth area is located between the hot stamping wheel and the positioning wheel, the hot stamping wheel is located at the working position, and the zipper and the hot stamping paper are attached and hot stamping operation is performed. When the fixed size area is located between the hot stamping wheel and the positioning wheel, the hot stamping wheel is located at the stop position, and the zipper and the hot stamping paper are separated. The power mechanism is arranged on the frame, and is used to drive the hot stamping wheel to rotate. The heating mechanism is arranged on one side of the hot stamping mechanism, and is used to heat the hot stamping paper at the hot stamping wheel. The sensing mechanism includes a sensing block, a guide seat and a sensing probe.
