Description

Technical Field

[0001] This utility model relates to the field of hot stamping machine technology, and in particular to an adjustable fixed shaft for a roll paper hot stamping machine. Background Technology

[0002] Hot stamping is a special printing process that does not use ink. It involves applying electroplated aluminum foil to the surface of a substrate under specific temperature and pressure. A hot stamping machine is the equipment used to perform this process. A perfect hot stamping effect depends primarily on the harmonious balance of temperature, pressure, and speed. Therefore, to control the quality of hot stamping, it is essential to master the appropriate hot stamping temperature, pressure, and speed.

[0003] In existing technology, the adjustable fixed shaft of a roll paper hot stamping machine is one of its core components. It is mainly used to support and adjust the position of the roll material (such as paper, film, etc.) to ensure stable tension and accurate pattern alignment during the hot stamping process. However, the traditional fixed shaft adjustment method of roll paper hot stamping machines often uses handwheels, screws or locking handles to adjust the position of the shaft. This makes the traditional manual adjustment method require adjusting the position of both ends of the fixed shaft separately, which is inconvenient and prone to causing uneven height at both ends of the fixed shaft.

[0004] To address this issue, an adjustable fixed shaft for a roll paper hot stamping machine is proposed, which has the advantage of easy coordination between the two ends of the fixed shaft, thereby solving the problems mentioned in the background technology. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable fixed shaft for a roll paper hot stamping machine.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable fixed shaft for a roll paper hot stamping machine, including a frame. A drive motor is fixedly installed on the left side wall of the frame, and a lower fixed shaft is fixed to the output end of the drive motor via a coupling. An upper fixed shaft is provided above the lower fixed shaft, and a transmission rod is provided above the upper fixed shaft. A reduction motor connected to the left side wall of the frame is provided above the drive motor, and the output end of the reduction motor is connected to the transmission rod via a coupling. The surface of the transmission rod is connected to the top of the frame via a shaft seat, and a gear is fixed to the surface of the transmission rod. Adjustment ports are provided on both sides of the frame, and adjustment seats are slidably installed in the adjustment ports. An installation groove is provided on the side of the adjustment seat facing the upper fixed shaft, and the installation groove is connected to the shaft of the upper fixed shaft via a bearing seat. A ruler is fixed to the top of the adjustment seat by screws, and the ruler meshes with the gear on the surface of the transmission rod.

[0007] As a further description of the above technical solution: a displacement sensor is embedded in the bottom of the adjusting seat of the upper fixed shaft, and a PLC controller is installed on the base below the geared motor, and the PLC controller is electrically connected to the geared motor through a relay.

[0008] As a further description of the above technical solution: T-shaped sliders are fixed on both sides of the adjustment seat, and slide rails are fixed to the left and right sides inside the adjustment port by screws, and the slide rails are slidably connected to the T-shaped sliders.

[0009] As a further description of the above technical solution: both the upper fixed shaft and the lower fixed shaft are made of high-strength steel or aluminum alloy, and the surfaces of the upper fixed shaft and the lower fixed shaft are coated with an anti-rust layer.

[0010] As a further description of the above technical solution: the mounting groove of the adjustment seat has a square structure, and several screw holes are opened on the inner side of the mounting groove of the adjustment seat.

[0011] As a further description of the above technical solution: two locking components are symmetrically arranged on the side wall of the frame, and several threaded knobs are installed at equal intervals on the surfaces of the two locking components.

[0012] This utility model has the following beneficial effects:

[0013] In this invention, by starting the geared motor installed on the frame, the geared motor drives the transmission rod fixed at its output end to rotate, causing the two gears on the surface of the transmission rod to rotate. At this time, since an adjustment seat is slidably installed in the adjustment port on both sides of the frame, and the adjustment seat is connected to the shaft of the upper fixed shaft through a bearing seat, and a ruler is provided on the top of the adjustment seat to mesh with the gears, as the gears on the surface of the transmission rod rotate, the ruler drives the adjustment seat to move up and down in the adjustment port, and drives the upper fixed shaft to move closer to or away from the lower fixed shaft, realizing the coordinated lifting and lowering adjustment of both ends of the upper fixed shaft. Compared with the prior art, this invention solves the problem of unbalanced height adjustment at both ends caused by the traditional manual adjustment method.

[0014] In this invention, a displacement sensor is installed at the bottom of the adjustment seat on the left end of the upper fixed shaft. When the height of the upper fixed shaft is adjusted, the displacement sensor can detect the displacement of the upper fixed shaft in real time and feed it back to the PLC controller. When the displacement reaches the preset value range of the PLC controller, the PLC controller cuts off the power supply of the geared motor through a relay. Combined with the ring lock setting at the output end of the geared motor, the upper fixed shaft can be locked at any lifting position, thereby achieving the effect of accurately adjusting the displacement of the upper fixed shaft.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] According to an embodiment of the present invention, an adjustable fixed shaft for a roll paper hot stamping machine is provided.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4 As shown, the adjustable fixed shaft of the roll paper hot stamping machine according to an embodiment of the present utility model includes a frame 1. A drive motor 2 is fixedly installed on the left side wall of the frame 1, and a lower fixed shaft 3 is fixed to the output end of the drive motor 2 through a coupling. An upper fixed shaft 4 is provided above the lower fixed shaft 3, and a transmission rod 6 is provided above the upper fixed shaft 4. A reduction motor 5 connected to the left side wall of the frame 1 is provided above the drive motor 2, and the output end of the reduction motor 5 is connected to the transmission rod 6 through a coupling. The surface of the transmission rod 6 is connected to the top of the frame 1 through a shaft seat, and a gear 10 is fixed to the surface of the transmission rod 6. Adjustment ports 8 are provided on both sides of the frame 1, and adjustment seats 7 are slidably installed in the adjustment ports 8. An installation groove 14 is provided on the side of the adjustment seat 7 facing the upper fixed shaft 4, and the installation groove 14 is connected to the shaft of the upper fixed shaft 4 through a bearing seat. A ruler 11 is fixed to the top of the adjustment seat 7 by screws, and the ruler 11 is meshed with the gear 10 on the surface of the transmission rod 6.

[0024] In one embodiment, a displacement sensor 13 is embedded in the bottom of the adjusting seat 7 of the upper fixed shaft 4, and a PLC controller 12 is installed on the base below the geared motor 5. The PLC controller 12 is electrically connected to the geared motor 5 through a relay. With this structure, combined with the ring lock at the output end of the geared motor 5, the upper fixed shaft 4 can be locked at any lifting position, achieving the effect of precisely adjusting the displacement of the upper fixed shaft 4. The drive motor 2 and the geared motor 5 are controlled by manually starting and stopping the switch. The wiring diagram of the power components and the power supply are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail. The geared motor 5 can be an S-series geared motor, an NMRV-series geared motor, an RV-series geared motor, a K-series geared motor, or an F-series geared motor. All of the above geared motors have a self-locking function. By adjusting the distance between the upper fixed shaft 4 and the lower fixed shaft 3, it is easy to unwind and rewind rolls of paper of different thicknesses. Alternatively, the upper fixed shaft 4 can be used alone to connect the roll of paper to ensure stable tension and accurate pattern alignment during the hot stamping process.

[0025] In one embodiment, T-shaped sliders 16 are fixed on both sides of the adjusting seat 7, and slide rails 9 are fixed to the left and right sides of the adjusting port 8 by screws. The slide rails 9 and the T-shaped sliders 16 are slidably connected. This structure increases the stability of the adjusting seat 7 during the lifting and lowering movement.

[0026] In one embodiment, both the upper fixed shaft 4 and the lower fixed shaft 3 are made of high-strength steel or aluminum alloy, and the surfaces of the upper fixed shaft 4 and the lower fixed shaft 3 are coated with an anti-rust layer. This structure extends the service life of the upper fixed shaft 4 and the lower fixed shaft 3.

[0027] In one embodiment, the mounting groove 14 of the adjusting seat 7 has a square structure, and several screw holes 15 are provided on the inner side of the mounting groove 14 of the adjusting seat 7. This structure facilitates the connection between the adjusting seat 7 and the upper fixed shaft 4.

[0028] In one embodiment, two locking elements are symmetrically arranged on the side wall of the frame 1, and several threaded knobs are equidistantly installed on the surface of the two locking elements. With this structure, the adjusting seat 7 can be directly fixed by the threaded knobs, thereby improving the reliability of the position of the upper fixed shaft 4.

[0029] Working principle:

[0030] In use, the upper fixed shaft 4 is first installed above the lower fixed shaft 3. To ensure stable tension and accurate pattern alignment during hot stamping, when the height of the upper fixed shaft 4 needs to be adjusted, the geared motor 5 installed on the frame 1 is started. This causes the geared motor 5 to drive the transmission rod 6 fixed at its output end to rotate, causing the two gears 10 on the surface of the transmission rod 6 to rotate. At this time, since an adjustment seat 7 is slidably installed in the adjustment port 8 on both sides of the frame 1, and the adjustment seat 7 is connected to the shaft of the upper fixed shaft 4 through a bearing seat, and the top of the adjustment seat 7 is provided with a ruler 11 that meshes with the gears 10, the transmission rod 6 rotates as the surface of the transmission rod 6 rotates. The rotation of gear 10 causes the ruler 11 to move the adjusting seat 7 up and down within the adjusting port 8, and also causes the upper fixed shaft 4 to move closer to or further away from the lower fixed shaft 3, thus achieving coordinated lifting and lowering adjustment of both ends of the upper fixed shaft 4. At the same time, the displacement sensor 13 can detect the displacement of the upper fixed shaft 4 in real time and feed it back to the PLC controller 12. When the displacement reaches the preset value range of the PLC controller 12, the PLC controller 12 cuts off the power supply of the geared motor 5 through the relay. Combined with the ring lock setting at the output end of the geared motor 5, the upper fixed shaft 4 is locked at any lifting and lowering position, thus achieving the effect of precisely adjusting the displacement of the upper fixed shaft 4.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
