Description

Technical Field

[0001] The invention belongs to the technical field of hot stamping machine auxiliary machinery, and in particular relates to a hot stamping machine auxiliary roll changing system and a use method thereof. Background Art

[0002] In the production process of tipping paper in the flexible packaging industry, it is necessary to perform electrochemical aluminum hot stamping on the tipping paper. The production process is as follows: a. insert the 3-inch unwinding air-expanding shaft 2 into the paper core tube in the middle of the anodized aluminum roll 1, and manually carry the anodized aluminum roll to the anodized aluminum transport trolley 12 and push it to the unwinding position of the equipment. Manually raise the hydraulic car so that the air-expanding shaft in the center of the anodized aluminum is concentric with the air-top brackets on both sides of the equipment, and manually start the air-top bracket to support the air-expanding shaft; b. adjust the left and right positions of the anodized aluminum roll to inflate the air-expanding shaft and then pass the anodized aluminum through the hot stamping plate 5 and the hot stamping rubber roller 6 to reach the rewinding air-expanding shaft 4; c. after the equipment is running, the pattern on the anodized aluminum is transferred to the tipping paper through the heat and pressure of the hot stamping plate; d. due to the inherent production process of the tipping paper, the pattern transferred on the anodized aluminum is in the shape of strips or bands in the longitudinal direction, and there are many gaps between the bands so that the anodized aluminum can be reused, and some can be reused 7-8 times. When the anodized aluminum is unwinded, the rewinding side is retracted into a reel 3, see attached Figure 1 .

[0003] In daily use, when the anodized aluminum is unwound, the reel side is reeled into a reel. One reel usually weighs about 40kg. Employees need to use a manual hydraulic car to lift and unload the anodized aluminum reel, and then push the anodized aluminum from the reel side to the unwinding side to repeat the above installation actions, install the anodized aluminum on the unwinding side, and reuse it.

[0004] Employees have a large workload of unloading and changing electroplated aluminum rolls every day, and the labor intensity is high. Therefore, an auxiliary roll changing system was developed to replace manual labor, thereby improving the production efficiency of unloading and changing electroplated aluminum rolls in hot stamping machines. Summary of the invention

[0005] In view of the deficiencies in the above-mentioned prior art, the purpose of the present invention is to provide an auxiliary roll changing system for a hot stamping machine, which can replace manual labor and thus improve the production efficiency of unloading and changing rolls of anodized aluminum in hot stamping machines.

[0006] The present invention provides an auxiliary roll changing system for a hot stamping machine, comprising a material unloading system, a transfer system, an anodized aluminum reversing system and an electrical control system.

[0007] The unloading system includes: a linear guide slider, a base, a 180-degree rotating seat, a lifting shaft seat, a lifting cylinder, a limit key bar, a lifting shaft, a bracket,

[0008] The 180-degree rotating seat is installed on the base, and the base is installed on the linear guide slider. The bracket is installed on the lifting shaft, and the lower end of the lifting shaft is installed on the cylinder shaft of the lifting cylinder. A hole with the same diameter as the lifting shaft is opened in the middle of the upper end face of the lifting shaft seat, and a keyway is machined on one side of the hole. The limit key strip is installed on the outer cylindrical surface of the lifting shaft, and is installed in the hole at the upper end of the lifting shaft seat and can slide up and down.

[0009] The transfer system includes: a rack, a 120 synchronous motor and its running gear, a winding limit proximity switch, an unwinding limit proximity switch, a linear guide.

[0010] The 120 synchronous motor and its running gear are installed below the base, the running gear meshes with the rack, the rack and the linear guide are installed on the equipment floor together, and the winding limit proximity switch and the unwinding limit proximity switch are respectively installed on the linear guide directly below the winding and unwinding positions.

[0011] The aluminized paper commutation system includes: a 180-degree rotating cylinder, an opposed infrared switch.

[0012] The shaft head of the 180-degree rotating seat in the unloading system is connected to the rotating shaft core of the 180-degree rotating cylinder. The 180-degree rotating cylinder is fixed to the base by 4 M10 screws. The opposed infrared switch is installed on the equipment wall panel below the middle position between the equipment's winding and unwinding shafts and can sense the position of the unloading system.

[0013] The electrical control system is prior art and consists of a PLC, a synchronous motor, a relay, and a proximity switch, which will not be elaborated here.

[0014] In the preferred disclosed example of the present invention, the base has dimensions of width 400mm * length 650mm * thickness 26mm, with a Φ150mm hole in the middle for installing a 6020 bearing, and the bearing is connected to the 180-degree rotating seat in the middle.

[0015] In the preferred disclosed example of the present invention, the 180-degree rotating seat has dimensions of width 300mm * length 600mm * thickness 20mm, with a lifting shaft seat installed on it, and a Φ100 shaft is made at the center of the diagonal on the bottom and installed on the base.

[0016] In the preferred disclosed example of the present invention, the diameter of the lifting shaft seat is Φ125mm, and the diameter of the lifting cylinder is Φ80mm.

[0017] In the preferred disclosed example of the present invention, the lifting shaft is a hollow steel pipe with a diameter of Φ80mm and a wall thickness of 8mm, and is an integrally formed structure with closed upper and lower end faces.

[0018] In a preferred disclosed example of the present invention, the bracket is a semi-cylindrical structure with an outer diameter of 100 mm, an inner diameter of 80 mm, and a width of 30 mm, and is connected to the lifting shaft by two M8 countersunk screws.

[0019] The present invention also relates to a method for using the auxiliary roll changing system of a hot stamping machine, comprising the following steps:

[0020] A: When the first winding of the anodized aluminum is completed, the unloading system receives a signal and the lifting cylinder works to lift the bracket to hold the winding air shaft. The brackets at both ends of the air shaft retract, and the lifting cylinder lowers the anodized aluminum roll. The travel switch on the cylinder receives a signal and starts the 120 synchronous motor and its running gear, driving the anodized aluminum roll to run in the unwinding direction;

[0021] B: When it runs to the middle position of the wall panel of the hot stamping machine station (on the equipment wall panel below the middle position between the equipment unwinding and rewinding shafts), the infrared switch is triggered, and the 180-degree rotating seat is started to rotate the anodized aluminum roll 180 degrees (anodized aluminum has a front side and a back side, and only the front side of the anodized aluminum can be used. Therefore, each time the anodized aluminum is taken from the unwinding position to the rewinding position, if it is taken to the unwinding position again for direct unwinding, the direction will be reversed, and it must be rotated 180 degrees before it can be used);

[0022] C: After the rotation is completed, the system detects whether the air-expanding shaft at the unwinding position has been manually taken. If the detection passes, the system continues to run. After sensing the unwinding limit proximity switch at the unwinding position, it stops running and starts to lift the anodized aluminum. When the upper induction switch on the lifting cylinder receives the signal, it stops, and then the brackets at both ends of the air-expanding shaft extend to support both ends of the air-expanding shaft;

[0023] D: After detecting that both ends of the air-inflated shaft have reached the position, the bracket descends and automatically turns back to run to the middle position of the wall panel of the hot stamping machine station (on the equipment wall panel below the middle position between the equipment placing and winding shafts), triggering the infrared switch, starting the 180-degree rotating seat to rotate 180 degrees to return to the original position and then run to the winding position. After the winding limit proximity switch is triggered, the system stops and waits for the next operation.

[0024] In the preferred disclosed example of the present invention, in the step C, both ends of the air expansion shaft are also designed with a 1:20 cone with a large head of Φ40mm and a length of 30mm (1:20 is the taper ratio of Morse 4#, which is widely used in lathes, milling machines and other occasions that require high concentricity, easy loading and unloading, and large torque transmission), and a clutch with toothed clutch is designed at the root of the cone for transmission.

[0054] Example 3

[0055] A method for using a hot stamping machine auxiliary roll changing system comprises the following steps:

[0056] A: When the anodized aluminum completes the first winding, the unloading system receives a signal and the lifting cylinder 18 works to lift the bracket to hold the winding air shaft. The brackets at both ends of the air shaft retract, and the lifting cylinder 18 lowers the anodized aluminum roll. The travel switch on the cylinder receives a signal and starts the 120 synchronous motor and its running gear 19, driving the anodized aluminum roll to run in the unwinding direction;

[0057] B: When it runs to the middle position of the wall panel 11 of the hot stamping machine station (the equipment wall panel below the middle position between the equipment unwinding and rewinding shafts), the infrared switch 26 is triggered, and the 180-degree rotating seat 16 is started to rotate the anodized aluminum roll 180 degrees (the anodized aluminum has a front side and a back side, and only the front side 9 of the anodized aluminum can be used. Therefore, each time the anodized aluminum is taken from the unwinding position to the rewinding position, if it is taken to the unwinding position again for unwinding, the direction is reversed, and it must be rotated 180 degrees before it can be used);

[0058] C: After the rotation is completed, the system detects whether the air-expanding shaft at the unwinding position has been manually taken. If the detection passes, the system continues to run. After sensing the unwinding limit proximity switch 25 at the unwinding position, it stops running and starts to lift the anodized aluminum. When the upper induction switch on the lifting cylinder 18 receives the signal, it stops, and then the brackets at both ends of the air-expanding shaft extend to support the two ends of the air-expanding shaft;

[0059] D: After detecting that both ends of the air-inflated shaft have reached the position, the bracket 23 descends and automatically turns back to run to the middle position of the hot stamping machine station wall panel 11 (on the equipment wall panel below the middle position between the equipment placing and winding shafts), triggering the infrared switch 26, starting the 180-degree rotating seat 16 to rotate 180 degrees to return to the original position and then run to the winding position. After triggering the winding limit proximity switch 24, the system stops and waits for the next operation.

[0060] Example 4

[0061] A method for using an auxiliary roll-changing system of a gilding machine, comprising the following steps:

[0062] A: When the aluminized paper completes the first winding, after the unloading system receives a signal, the lifting cylinder 18 works to raise the bracket to hold the winding air shaft, the brackets at both ends of the air shaft retract, and the lifting cylinder 18 lowers the aluminized paper reel. After the stroke switch on the cylinder receives a signal, the 120 synchronous motor and its running gear 19 are started, and the aluminized paper reel is run in the unwinding direction.

[0063] B: When it runs to the middle position of the gilding machine station wall panel 11 (on the equipment wall panel below the middle position between the equipment unwinding and winding shafts), the opposed infrared switch 26 is triggered, and the 180-degree rotating seat 16 is started to rotate the aluminized paper reel by 180 degrees (the aluminized paper has a front and a back, and only the front side 9 of the aluminized paper can be used. Therefore, every time the aluminized paper is received from the unwinding position to the winding position and then taken back to the unwinding position directly for unwinding and use, the direction is reversed, and it must be rotated by 180 degrees before it can be used).

[0064] C: After the rotation is completed, the system detects whether the unwinding air shaft has been manually taken. If the detection passes, the system continues to run. After the unwinding limit proximity switch 25 at the unwinding position is sensed, it stops running and starts to lift the aluminized paper. When the upper induction switch on the lifting cylinder 18 receives a signal, it stops. Subsequently, the brackets at both ends of the air shaft extend to hold both ends of the air shaft.

[0065] D: After detecting that both ends of the air shaft have been pushed to the position, the bracket 23 descends and automatically runs back to the middle position of the gilding machine station wall panel 11 (on the equipment wall panel below the middle position between the equipment unwinding and winding shafts). When the opposed infrared switch 26 is triggered, the 180-degree rotating seat 16 rotates 180 degrees to return to the original position and then runs towards the winding position. After the winding limit proximity switch 24 is triggered, the system stops and waits for the next run.

[0066] In step C, there are also designed cones with a large head of Φ40mm and a length of 30mm and a taper of 1:20 at both ends of the air shaft (1:20 is the taper ratio of Morse No. 4, and this ratio is widely used in occasions such as lathes and milling machines that require high concentricity, easy loading and unloading, and large torque transmission). A clutch with a tooth clutch is designed at the root of the cone for transmission.
