Description

Technical Field

[0001] This utility model relates to the technical field of card mounting machines, and in particular to a phase adjustment device for a card mounting machine. Background Technology

[0002] A card laminating machine is a paper processing device that laminates face paper and cardstock together, replacing manual lamination of face paper and cardstock. The feeder device in the card laminating machine is used to separate and convey the cardstock. It shares a motor with the front conveyor device. While the motor drives the conveyor device to rotate, it also drives the feeder device through a long shaft, thus synchronizing the actions of the feeder device and the conveyor device. When the feeder device conveys the cardstock, the time when the cardstock arrives at the front guide needs to be adjusted to avoid problems such as the front guide hitting the paper or inaccurate positioning caused by the cardstock arriving too early or too late. Adjustment usually requires stopping the equipment and loosening the transmission component of the feeder device. The phase between the feeder device and the front guide is adjusted by rotating the angle of the transmission component. After adjustment, the transmission component is tightened. The operation is cumbersome. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a simple and convenient phase adjustment device for a card mounting machine.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a phase adjustment device for a card mounting machine, comprising a frame, a feeder, and a long shaft driven by the feeder. A synchronous pulley set is mounted on the frame, and the synchronous pulley set is driven by a feeder head drive wheel. The long shaft is connected to the feeder head drive wheel at the other end relative to the feeder. A phase adjustment component is driven between the synchronous pulley set and the feeder head drive wheel. The phase adjustment component includes a harmonic drive reducer and a driving component capable of driving the harmonic drive reducer to rotate in either the forward or reverse direction. The harmonic drive reducer includes an input wheel, an input phase wheel connected to the input wheel, an output wheel, and an output phase wheel connected to the output wheel. The input phase wheel and the output phase wheel are driven by each other. The input phase wheel is driven by the synchronous pulley set via a belt. The output phase wheel is driven by the feeder head drive wheel. The driving component is driven by the output phase wheel.

[0005] By adopting the above technical solution, the input phase wheel connected to the input wheel and the output phase wheel connected to the output wheel are equivalent to phase adjusters. Under the forward or reverse drive of the driving component, the output phase wheel accelerates or decelerates while rotating, achieving easy and accurate adjustment of the time when the feeder conveys the paper jam to the front guide without stopping the machine. When there is no need to adjust the phase distance between the feeder and the front guide, the synchronous belt pulley group drives the input phase wheel to rotate. Since the output phase wheel is connected to the input phase wheel, the output phase wheel rotates together with the input phase wheel, and the output phase... The feeder head drive wheel rotates synchronously, and the two ends of the long shaft are respectively connected to the feeder head drive wheel and the feeder drive, so that the rotation of the long shaft drives the feeder to move and convey the paper jam. The structure is compact and has good stability. When the feeder and the front guide need to be adjusted in phase, the drive component is operated to rotate forward or in reverse according to the requirements, so that the output phase wheel can be further accelerated or decelerated while rotating on its own, so that the feeder conveys the paper jam to the front guide earlier or later. The phase distance between the two is simple and convenient to adjust. Using a harmonic drive reducer to adjust the phase can achieve high-precision and stable transmission, improve structural stability, and reduce errors.

[0006] The present invention further comprises: the driving component is a motor.

[0007] By adopting the above technical solution, the transmission efficiency is improved by driving the rotation with a motor, the accuracy is higher, and the phase will not change after adjustment, thus improving the stability of the structure. The driving component can also be set as a handwheel, which is low in cost.

[0008] The present invention further comprises: an output shaft at one end of the motor is connected to a driving wheel, and a driven wheel is provided on the other side of the output phase wheel relative to the input phase wheel. The driving wheel is connected to the driven wheel via a conveyor belt.

[0009] By adopting the above technical solution, the motor drives the active wheel to rotate, and the active wheel drives the driven wheel to rotate synchronously through the conveyor belt. The rotation of the driven wheel causes the output phase wheel to rotate faster or slower while rotating on its own, thereby realizing the indirect drive of the motor, which has high transmission accuracy and improves system stability.

[0010] The present invention further comprises: a mounting plate fixedly mounted on one side of the motor; a support rod connected to the frame at the position corresponding to the mounting plate; a mounting hole opened at the other end of the support rod relative to the frame; a connecting hole provided at the position corresponding to the mounting hole on the mounting plate; and the mounting hole and the connecting hole being connected by bolts.

[0011] By adopting the above technical solution, the mounting plate is used for mounting the motor on the frame, and the support rods play the role of mounting and supporting the motor, resulting in a stable structure. Preferably, there are four support rods distributed at the four corners of the mounting plate, making the structure more stable. The mounting plate and the support rods are connected by bolts, which makes disassembly and assembly convenient and the structure stable.

[0012] The present invention is further characterized in that the connecting hole is a vertically arranged elongated hole.

[0013] By adopting the above technical solution, the installation position of the motor on the frame can be adjusted up and down along the position of the long hole. The driving wheel and the driven wheel are arranged vertically, and the driving wheel is mounted on the mounting plate. When the position of the mounting plate is adjusted, the conveyor belt at the position of the driving wheel and the driven wheel can also be tensioned, further improving the reliability of the structure.

[0014] The present invention further comprises: the synchronous pulley group including a first synchronous pulley and a second synchronous pulley rotatably connected on the same shaft; the first synchronous pulley is connected to the input phase pulley via a belt; the second synchronous pulley is connected to a driven pulley via a belt; and a transition pulley group is provided for the transmission connection between the output phase pulley and the feeder head drive pulley; the transition pulley group includes a first transition pulley and a second transition pulley rotatably connected on the same shaft; the first transition pulley is connected to the feeder head drive pulley via a belt; and the second transition pulley is connected to the output phase pulley via a belt.

[0015] By adopting the above technical solution, the feeder head drive wheel, synchronous belt pulley set, transition pulley set and harmonic drive reducer are connected by corresponding belts to achieve synchronous rotation, which has high transmission efficiency, adapts to different working conditions and is convenient for maintenance.

Detailed Implementation

[0022] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0023] See appendix Figure 1-5This utility model discloses a phase adjustment device for a card mounting machine, including a frame 1, a feeder 2, and a long shaft 3 connected to the feeder. A synchronous pulley set 7 is mounted on the frame 1, and the synchronous pulley set 7 is connected to a feeder head drive wheel 4. The other end of the long shaft 3 relative to the feeder 2 is connected to the feeder head drive wheel 4. A phase adjustment component is connected between the synchronous pulley set 7 and the feeder head drive wheel 4. The phase adjustment component includes a harmonic drive reducer 5 and a mechanism capable of driving the harmonic drive reducer to rotate in either the forward or reverse phase. The drive component 6, the harmonic drive reducer 5 includes an input wheel 501 and an input phase wheel 502 connected to the input wheel 501, an output wheel 503 and an output phase wheel 504 connected to the output wheel 503. The input phase wheel 502 and the output phase wheel 504 are connected in a driving connection. The input phase wheel 502 is connected in a driving connection to the synchronous pulley group 7 via a belt. The output phase wheel 504 is connected in a driving connection to the feeder head drive wheel 4. The drive component 6 is connected in a driving connection to the output phase wheel 504. The input phase wheel 502 connected to the input wheel 501 and the output phase wheel 504 connected to the output wheel 503 act as phase adjusters. Under the forward or reverse drive of the drive unit 6, the output phase wheel 504 accelerates or decelerates while rotating, achieving easy and accurate adjustment of the time when the feeder 2 delivers the paper jam to the front guide without stopping the machine. When there is no need to adjust the phase distance between the feeder 2 and the front guide, the synchronous belt pulley group 7 drives the input phase wheel 502 to rotate. Since the output phase wheel 504 is connected to the input phase wheel 502, the output phase wheel 504 rotates together with the input phase wheel 502, and the output phase wheel 504 drives the feeder head drive wheel 4 synchronously. The long shaft 3 rotates, and its two ends are respectively connected to the feeder head drive wheel 4 and feeder 2, so that the rotation of the long shaft 3 drives the feeder 2 to convey the paper jam. The structure is compact and has good stability. When the feeder 2 and the front guide need to be adjusted in phase, the drive component 6 is operated to rotate in the forward or reverse direction according to the requirements, so that the output phase wheel 504 further speeds up or slows down its rotation while rotating on its own, so that the feeder 2 conveys the paper jam to the front guide earlier or later. The phase distance between the two is simple and convenient to adjust. Using the harmonic drive reducer 5 to adjust the phase can achieve high-precision and stable transmission, improve structural stability, and reduce errors. The structure of the harmonic drive reducer 5 and the feeder 2 are existing technologies, so they will not be described in detail in this embodiment.

[0024] This invention further includes the following configuration: the driving component 6 is a motor 601. Driving rotation via the motor 601 improves transmission efficiency, increases precision, and ensures that the phase remains unchanged after adjustment, thus enhancing structural stability. The driving component 6 can also be configured as a handwheel, resulting in lower cost.

[0025] This invention further comprises: an output shaft at one end of the motor 601 connected to a driving wheel 9; and a driven wheel 10 connected to the output phase wheel 504 on the other side relative to the input phase wheel 502. The driving wheel 9 is connected to the driven wheel 10 via a conveyor belt 11. The motor 601 drives the driving wheel 9 to rotate, and the driving wheel 9 drives the driven wheel 10 to rotate synchronously via the conveyor belt 11. The rotation of the driven wheel 10 causes the output phase wheel 504 to rotate faster or slower while rotating on its own axis, thus achieving indirect drive of the motor 601, resulting in high transmission accuracy and improved system stability.

[0026] This utility model further comprises: a mounting plate 12 fixedly mounted on one side of the motor 601; a support rod 13 connected to the frame 1 corresponding to the mounting plate 12; a mounting hole 14 opened at the other end of the support rod 13 relative to the frame 1; and a connecting hole 15 provided on the mounting plate 12 corresponding to the mounting hole 14. The mounting hole 14 and the connecting hole 15 are connected by bolts. The mounting plate 12 is used for mounting the motor 601 on the frame 1. The support rod 13 serves to mount and support the motor 601, resulting in a stable structure. Preferably, there are four support rods 13, distributed at the four corners of the mounting plate 12, further enhancing the structural stability. The mounting plate 12 and the support rod 13 are connected by bolts, facilitating easy assembly and disassembly and ensuring structural stability.

[0027] This invention further features a vertically oriented elongated hole 15 for adjusting the mounting position of the motor 601 on the frame 1. The drive wheel 9 and driven wheel 10 are vertically aligned, with the drive wheel 9 mounted on the mounting plate 12. Adjusting the position of the mounting plate 12 also tensions the conveyor belt 11 at the positions of the drive wheel 9 and driven wheel 10, further improving the structural reliability.

[0028] This utility model further comprises: the synchronous pulley group 7 including a first synchronous pulley 701 and a second synchronous pulley 702 rotatably connected on the same shaft; the first synchronous pulley 701 is connected to the input phase pulley 502 via a belt; the second synchronous pulley 702 is connected to a driven pulley 703 via a belt; and a transition pulley group 8 is provided for the transmission connection between the output phase pulley 504 and the feeder head drive pulley 4. The transition pulley group 8 includes a first transition pulley 801 and a second transition pulley 802 rotatably connected on the same shaft; the first transition pulley 801 is connected to the feeder head drive pulley 4 via a belt; and the second transition pulley 802 is connected to the output phase pulley 504 via a belt.
