One end of the polyester film with the pattern to be cold-stamped is fixed to the empty film roll. The first supporting frame 2 drives the support rod 10 to rotate, so that the empty film roll rotates, and the polyester film is pulled to move. The paper cup raw cardboard is placed on the conveying platform 1, and the raw cardboard is moved on the conveying platform 1 under the polyester film through the transmission mechanism. According to the moving speed of the raw cardboard, the pressing time of the hydraulic press 7 is controlled by the operating table 5. When the hydraulic press 7 is pressed down, it drives the cold stamping device 8 to cold stamp the pattern on the polyester film onto the raw cardboard. By setting a retractable winding roller 20, the equipment can cold stamp polyester films of different specifications, and the patterns can be cold stamped at different positions, saving the cost of purchasing equipment of different specifications.
[0024] Reference Figure 4As shown, in this embodiment: the internal thread of the support rod 10 is connected to a threaded rod 21, and one end of the threaded rod 21 is fitted with the rear end of the winding roller 20. The user rotates the threaded rod 21 according to the specifications of the polyester film roll to move the threaded rod 21 inward, push the winding roller 20 inward, and clamp the polyester film roll. At the same time, the threaded rod 21 limits the winding roller 20 to prevent the vibration of the equipment from causing the winding roller 20 to move and causing the polyester film roll to fall off.
[0025] Reference Figure 5 As shown, in the present embodiment: the rear end of the winding roller 20 is fixedly connected with a tension spring 22, and the other end of the tension spring 22 is fixedly connected to one end inside the support rod 10. When the user replaces the polyester film roll, the threaded rod 21 is rotated in the opposite direction to move the threaded rod 21 outward to release the limit on the winding roller 20. Under the tension of the tension spring 22, the winding roller 20 is pulled back to the inside of the support rod 10 to release the clamping of the polyester film roll, so that the polyester film roll can be maliciously removed and replaced.
[0026] Reference Figure 5 As shown, in this embodiment: limiting grooves 23 are provided at the top and bottom of the support rod 10, and limiting sliders 24 are fixedly connected to the top and bottom of the winding roller 20. When the user rotates the threaded rod 21 to drive the winding roller 20 to move, the limiting sliders 24 at the top and bottom of the winding roller 20 move inside the limiting grooves 23, limiting the movement of the winding roller 20 and preventing the winding roller 20 from escaping from the inside of the support rod 10.
[0027] Reference Figure 1 , Figure 2 and Figure 3 As shown, in the present embodiment: a first slide groove 11 is provided on one side of the conveying platform 1, a first slider 14 is slidably connected inside the first slide groove 11, a correction rod 12 is slidably connected inside the first slider 14, a plurality of limiting grooves 13 are provided on one side of the conveying platform 1, one side of the correction rod 12 is slidably connected to the inside of the correction rod 12, when the user puts the raw paperboard on the conveying platform 1, the user passes the raw paperboard through the middle of the correction rod 12, pulls the correction rod 12 out of the limiting groove 13, so that the correction rod 12 can move, and the raw paperboard is corrected by moving the position of the correction rod 12 to prevent the position of the raw paperboard from being offset and causing the position error of the cold stamping pattern.
[0028] Reference Figure 3As shown, in the present embodiment: the rear end of the correcting rod 12 is fixedly connected with a reset spring 15, and the other end of the reset spring 15 is fixedly connected to the rear end inside the first sliding block 14. When the user pulls the correcting rod 12 to disengage from the interior of the limiting groove 13, the reset spring 15 at the rear end of the correcting rod 12 accumulates force, moves the correcting rod 12 to a desired position, and then releases the correcting rod 12. Under the pulling force of the reset spring 15, the correcting rod 12 is pulled to disengage from and enter the interior of the limiting groove 13, thereby limiting the correcting rod 12. At the same time, the pulling force of the reset spring 15 prevents the correcting rod 12 from being affected by the vibration of the equipment and disengaging from the interior of the limiting groove 13.
[0029] Reference Figure 3 As shown, in this embodiment: second sliding grooves 16 are opened on both sides of the inside of the first slider 14, and second sliders 17 are fixedly connected on both sides of the correcting rod 12. When the user pulls the correcting rod 12, the second sliders 17 on both sides of the correcting rod 12 move inside the second sliding grooves 16 to limit the movement of the correcting rod 12 and prevent the correcting rod 12 from escaping from the inside of the first slider 14.
[0030] Working principle: The user rolls the polyester film that needs cold stamping pattern on the inner side of the winding roller 20, and loads an empty film roll on the inner side of another winding roller 20. One end of the polyester film that needs cold stamping pattern is fixed to the empty film roll. The first support frame 2 drives the support rod 10 to rotate, so that the empty film roll rotates, and the polyester film is pulled to move. The raw paperboard of the paper cup is placed on the conveying platform 1. Under the polyester film, the raw paperboard is moved on the conveying platform 1 through the conveying mechanism. According to the moving speed of the raw paperboard, the pressing time of the hydraulic press 7 is controlled through the operating table 5. When the hydraulic press 7 is pressed down, it drives the cold stamping device 8 to The pattern on the polyester film is cold stamped onto the raw cardboard. By setting a retractable winding roller 20, the equipment can cold stamp polyester films of different specifications. The threaded rod 21 is rotated to move the threaded rod 21 inward, pushing the winding roller 20 to move inward, clamping the polyester film roll, and at the same time, the threaded rod 21 limits the winding roller 20 to prevent the vibration of the equipment from causing the winding roller 20 to move. When changing the polyester film roll, the threaded rod 21 is rotated in the opposite direction to move the threaded rod 21 outward to release the limit on the winding roller 20. Under the tension of the tension spring 22, the winding roller 20 is pulled back to the inside of the support rod 10. The clamping of the polyester film roll is released. In the process of rotating the threaded rod 21 to drive the winding roller 20 to move, the limit sliders 24 at the top and bottom of the winding roller 20 move inside the limit slide groove 23 to limit the movement of the winding roller 20 and prevent the winding roller 20 from being separated from the inside of the support rod 10. When the raw cardboard is placed on the conveying platform 1, the raw cardboard is passed through the middle of the correcting rod 12, and the correcting rod 12 is pulled out of the inside of the limit groove 13 so that the correcting rod 12 can move. The raw cardboard is corrected by moving the position of the correcting rod 12, and the correcting rod 12 is pulled out of the inside of the limit groove 13. During the process, the reset spring 15 at the rear end of the correcting rod 12 accumulates force, and the correcting rod 12 is moved to the required position and then released. Under the pulling force of the reset spring 15, the correcting rod 12 is pulled out of the limiting groove 13 to limit the correcting rod 12. At the same time, the pulling force of the reset spring 15 prevents the correcting rod 12 from being affected by the vibration of the equipment and from being separated from the limiting groove 13. In the process of pulling the correcting rod 12, the second sliders 17 on both sides of the correcting rod 12 move inside the second slide groove 16 to limit the movement of the correcting rod 12 and prevent the correcting rod 12 from being separated from the first slider 14.
