Description

Technical Field

[0001] This utility model relates to the field of ink stack technology for heat press machines, specifically to a stable double-head ink stack for use in heat press machines. Background Technology

[0002] Heat transfer machines can transfer various heat transfer designs onto fabrics such as cotton, linen, and synthetic fibers. They can also perform heat treatment processes such as screen printing, plastisol, and foaming. Furthermore, they can bake color codes, portrait photos, and landscape patterns onto ceramic plates and metal plates. They are particularly suitable for making medals, commemorative badges, and T-shirts, and are economical, practical, and produce exquisite designs.

[0003] There are many commercially available lifting ink stacks for heat press printers. However, in pursuit of low costs, these types of ink stacks often use sheet metal slots and cylindrical pins for vertical positioning. This constant friction between the cylindrical pins and the sheet metal slots causes wear and tear, leading to problems such as movement jamming, excessive gaps, and inaccurate positioning. This prevents the ink pad from accurately aligning with the printhead for sealing, ultimately reducing the printhead's lifespan or even damaging it. Therefore, we propose a stable, lifting dual-head ink stack for heat press printers. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a stable, lifting double-head ink stack for use in heat press machines.

[0005] The technical solution adopted by this utility model to solve its technical problem is a lifting and stable double-head ink stack applied to a heat press machine, including an internal thread synchronous wheel and a stepper motor. The power output end of the stepper motor is equipped with a motor synchronous wheel. A synchronous belt is wound around the outer wall of the motor synchronous wheel, and the synchronous belt is wound around the outer wall of multiple internal thread synchronous wheels. The multiple internal thread synchronous wheels are distributed in a U-shape, and a rotating shaft is respectively installed at their top and bottom ends. Driven bearings are respectively provided between the two sides of the motor synchronous wheel and the internal thread synchronous wheels, and a synchronous belt is wound around the outer wall of the driven bearing.

[0006] By adopting the above technical solution, the stepper motor drives the synchronous pulley to rotate, which in turn drives the internal thread synchronous pulley to rotate via the synchronous belt. The internal thread synchronous pulley rotates around the outer circumference of the screw, thereby causing the upper mounting sheet metal of the top locking connection to move vertically with the forward and reverse rotation of the screw. This allows for precise alignment and sealing of the print head, thus relatively improving the service life of the print head.

[0007] Specifically, the internal thread synchronous pulley is screwed to one side of the top rotating shaft and connected to a screw rod. Each internal thread synchronous pulley, rotating shaft, screw rod, driven bearing, synchronous belt, knob handle, stepper motor and motor synchronous pulley constitute a drive module. The bottom ends of the multiple drive modules are respectively set at the four corners of the lower mounting sheet metal, and the drive module is fixed to the top of the lower mounting sheet metal by the upper mounting sheet metal.

[0008] By adopting the above technical solution, a stepper motor drives a synchronous belt and an internal thread synchronous pulley to rotate, and the threads of the internal thread synchronous pulley drive a screw to drive the ink pad module to move up and down, achieving stable and precise lifting and lowering movements.

[0009] Specifically, the top of the stepper motor is equipped with a knob handle for manual adjustment and calibration.

[0010] By adopting the above technical solution, the zero position of the timing belt will deviate after long-term use. The position of the timing belt can be manually adjusted by turning the knob handle, thereby driving the print head to zero.

[0011] Specifically, a sensor is provided on one side of the upper sheet metal mounting, and a sensing plate is slidably connected inside the sensor, the sensing plate being mounted on the side wall of the ink pad module.

[0012] By adopting the above technical solution, the device is reset by sending a signal through the PLC control circuit based on the position of the sensing element.

[0013] Specifically, the top of each of the internal threaded synchronous pulleys is locked to the ink pad module via an M5 screw.

[0014] By adopting the above technical solution, the M5 screw is used in conjunction with the rotating shaft to lock and position the internal thread synchronous pulley below the ink pad module.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The technical solution of this application uses a stepper motor to drive the synchronous pulley of the motor to rotate, which in turn drives the internal thread synchronous pulley to rotate via a synchronous belt. The internal thread synchronous pulley rotates around the outer circumference of the screw, thereby causing the upper mounting sheet metal of the top locking connection to move vertically with the forward and reverse rotation of the screw. This allows for precise alignment and sealing of the print head, thus improving the service life of the print head. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a lifting and stable double-head ink stack applied to a heat press machine, including an internal thread synchronous wheel 1 and a stepper motor 7. The power output end of the stepper motor 7 is equipped with a motor synchronous wheel 8. The outer wall of the motor synchronous wheel 8 is wound with a synchronous belt 5, and the synchronous belt 5 is wound around the outer wall of a plurality of internal thread synchronous wheels 1. The plurality of internal thread synchronous wheels 1 are distributed in a U-shape and are respectively equipped with a rotating shaft 2 at their top and bottom ends. Driven bearings 4 are respectively provided between the two sides of the motor synchronous wheel 8 and the internal thread synchronous wheels 1, and the outer wall of the driven bearings 4 is wound with a synchronous belt 5.

[0024] In use, the stepper motor 7 drives the synchronous pulley 8 to rotate, which in turn drives the internal thread synchronous pulley 1 to rotate via the synchronous belt 5. The internal thread synchronous pulley 1 rotates on the outer circumference of the screw 3, thereby causing the upper mounting sheet metal 12, which is locked at the top, to move vertically with the forward and reverse rotation of the screw 3. This allows for precise alignment and sealing of the print head, thus improving the service life of the print head.

[0025] As shown in the figure, the internal thread synchronous pulley 1 is threaded through one side of the top rotating shaft 2 and connected to the screw 3. Each internal thread synchronous pulley 1, rotating shaft 2, screw 3, driven bearing 4, synchronous belt 5, knob handle 6, stepper motor 7 and motor synchronous pulley 8 constitute a drive module 10. The bottom ends of the multiple drive modules 10 are respectively set at the four corners of the lower mounting sheet metal 9, and the drive modules 10 are fixed to the top of the lower mounting sheet metal 9 by the upper mounting sheet metal 12.

[0026] In use, the stepper motor 7 drives the synchronous belt 5 and the internal thread synchronous pulley 1 to rotate, and the threads of the internal thread synchronous pulley 1 drive the screw 3 to drive the ink pad module 14 to move up and down to achieve stable and precise lifting action.

[0027] As shown in the figure, the top of the stepper motor 7 is provided with a knob handle 6 for manual adjustment and calibration.

[0028] During use, after a long period of use, the zero position of the synchronization belt 5 may deviate. The position of the synchronization belt 5 can be manually adjusted by turning the knob handle 6, which will then drive the print head to zero.

[0029] As shown in the figure, a sensor 11 is provided on one side of the upper mounting sheet metal 12, and a sensing sheet 13 is slidably connected inside the sensor 11. The sensing sheet 13 is installed on the side wall of the ink pad module 14.

[0030] In use, the sensor 11 senses the position of the sensing element 13 and sends a signal to reset the device via the PLC control circuit.

[0031] As shown in the figure, the top of each of the internal thread synchronous pulleys 1 is locked to the ink pad module 14 through the M5 screw 3.

[0032] In use, the M5 screw 3 is used in conjunction with the rotating shaft 2 to lock and position the internal thread synchronous wheel 1 below the ink pad module 14.

[0033] The working principle and usage process of this utility model are as follows: The stepper motor 7 drives the synchronous belt 5 and the internal thread synchronous pulley 1 to rotate. The threads of the internal thread synchronous pulley 1 drive the screw 3 to drive the ink pad module 14 to move up and down to achieve stable and precise lifting action. The stepper motor 7 drives the motor synchronous pulley 8 to rotate, which in turn drives the internal thread synchronous pulley 1 to rotate through the synchronous belt 5. The internal thread synchronous pulley 1 rotates on the outer circumference of the screw 3, thereby driving the upper mounting sheet metal 12, which is locked at the top, to move vertically with the forward and reverse rotation of the screw 3. This allows for precise alignment and sealing of the print head, which relatively improves the service life of the print head. After long-term use, the zero position of the synchronous belt 5 may deviate. The position of the synchronous belt 5 can be manually adjusted by turning the knob handle 6 to drive the print head to zero. The sensor 11 senses the position of the sensing plate 13 and sends a signal to reset the device through the PLC control circuit.
