Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a card transfer device and a printer. Background Technology

[0002] Currently, in order to address the printing of cards, printers specifically designed for cards have been introduced. These printers have a card feeding mechanism and a card clamping mechanism. The card feeding mechanism feeds the cards one by one, and the card clamping mechanism clamps the cards for printing.

[0003] In existing card feeding mechanisms, the cards are vertical. A pusher plate pushes the vertical cards down and into the card clamping mechanism, changing the cards from vertical to horizontal. This transfer method may cause card misalignment, resulting in incorrect positioning and affecting subsequent card clamping and printing. Utility Model Content

[0035] Understandably, referring to Figures 1 to 7 The present invention provides a card transfer device that uses a card-dispensing component 200 to push the card to move, so that the card is transferred from the card feeding mechanism 110 to the card clamping mechanism 120, thereby eliminating the position error problem caused by card offset and improving the working stability of the printer.

[0036] The card transfer device includes a frame 100 and a card feeding assembly 200. The frame 100 is equipped with a card feeding mechanism 110 and a card clamping mechanism 120. The card feeding mechanism 110 is used to feed cards, and the card clamping mechanism 120 is used to clamp cards for printing. The card feeding mechanism 110 includes horizontally arranged upper card feeding roller 111 and lower card feeding roller 112. The upper card feeding roller 111 is equipped with an upper pressure roller 113, and the lower card feeding roller 112 is equipped with a lower pressure roller 114. A gap adapted to the card thickness is formed between the upper pressure roller 113 and the lower pressure roller 114. The card feeding mechanism 110 can employ multiple sets of upper card feeding rollers 111 and lower card feeding rollers 112. Cards can be horizontally clamped between the upper pressure roller 113 and the lower pressure roller 114, and are clamped and conveyed forward by the cooperation of the upper pressure roller 113 and the lower pressure roller 114. The card clamping mechanism 120 is arranged outside the output end of the card feeding mechanism 110 to receive the card fed by the card feeding mechanism 110 and clamp the card for printing.

[0037] The card-dispensing assembly 200 is connected to the frame 100. Its function is to push the card forward after it disengages from the upper pressure roller 113 and lower pressure roller 114, ultimately feeding the entire card into the card-clamping mechanism 120. The card-dispensing assembly 200 includes a drive shaft 210 and a paddle 220. The lower end of the paddle 220 is connected to the drive shaft 210, and the upper end of the paddle 220 is provided with a pawl 221. The paddle 220 is located between the card-feeding mechanism 110 and the card-clamping mechanism 120, along the axial direction of the lower card-feeding roller 112. The pawl 221 is located outside the end of the lower pressure roller 114 and can abut against the lower card-feeding roller 112.

[0038] The pawl 221 is provided with a card-pushing curved surface 2211 for pushing the card. The design of the card-pushing curved surface 2211 allows the pawl 221 to contact the card during the card-pushing process, thereby effectively increasing the angle between the pawl 221 and the card and improving the stability and reliability of card pulling.

[0039] Reference Figures 4 to 7 During the card feeding process, the card is first placed between the upper pressure roller 113 and the lower pressure roller 114, where it is clamped and fed forward. When the card is fed to the output end of the card feeding mechanism 110, it disengages from the upper pressure roller 113 and the lower pressure roller 114. At this time, the card dispensing assembly 200 is activated, the drive shaft 210 drives the dispensing plate 220 to rotate, and the dispensing claw 221 pushes the card forward through the card dispensing curved surface 2211, finally feeding the entire card into the card clamping mechanism 120.

[0040] Understandably, to avoid card obstruction, the card feeder 220 is positioned low, below the card, when the card is being fed on the card feeding mechanism 110. Once the card passes the card feeder 221, the card-pushing assembly 200 activates. At this point, the angle between the card feeder 220 and the card is small. If the card feeder 221 were a straight structure, the friction between it and the card would be low, potentially preventing the card feeder 221 from pushing the card. Therefore, the card feeder 221 is equipped with a card-pushing curved surface 2211. During the card-pushing process, the curved surface 2211 contacts the card, effectively increasing the angle between the card feeder 221 and the card, thus improving the stability and reliability of the card-pushing mechanism. Furthermore, the card is horizontal throughout its transfer from the card feeding mechanism 110 to the card clamping mechanism 120. Using the card-pushing assembly 200 to move the card eliminates positional errors caused by card misalignment, improving the printer's operational stability.

[0041] In some embodiments of this invention, the paddle 220 has a structure with two symmetrically arranged claws 221. Each claw 221 is located at the upper end of the paddle 220 and corresponds to both sides of the pressure roller 114, allowing the paddle 220 to apply force to both sides of the card simultaneously, thereby more stably pushing the card forward. The clearance groove between the two claws 221 not only provides space for the pressure roller and prevents the claws 221 from colliding with the pressure roller, but also reduces interference between the card dispensing assembly 200 and the card feeding mechanism 110, making the card feeding process smoother.

[0042] During the operation of the card transfer device, when the card dispensing assembly 200 is activated, the two claws 221 of the card dispensing assembly 200 simultaneously act on both sides of the card. As the drive shaft 210 rotates, the paddle 220 drives the claws 221 to push the card along the card dispensing surface 2211 until the card is completely disengaged from the pressure roller and enters the card clamping mechanism 120. The design of the avoidance groove allows the claws 221 to flexibly avoid the pressure roller during the card pushing process, ensuring the smoothness of the card dispensing action and the accuracy of the card position.

[0043] It is understood that the card-dispensing surface 2211 is the part of the card-dispensing assembly 200 where the claw 221 contacts the card, and its shape plays a decisive role in the smooth transfer of the card. In this embodiment, the card-dispensing surface 2211 is designed as an arc surface. The arc surface helps to reduce friction when the claw 221 pushes the card, so that the card can be transferred more smoothly from the card feeding mechanism 110 to the card clamping mechanism 120.

[0044] In some embodiments, the card-pulling surface 2211 is a continuous arc surface, which allows the contact position between the card and the arc surface to change continuously during the process of the pawl 221 pushing the card, thereby providing a continuous and more uniform force and improving the stability of the card during the transfer process.

[0045] Reference Figure 3 In other embodiments, the card-pulling surface 2211 is designed to include two arc surfaces, namely a first arc surface and a second arc surface. The second arc surface is located near the paddle 220, and the first arc surface is located on the side of the second arc surface away from the paddle 220, with the radius of the first arc surface being larger than that of the second arc surface. During the process of the paddle 221 pushing the card, the first arc surface contacts the card first, followed by the second arc surface. Since the rotational angular velocity of the paddle 220 is fixed, the relative movement speed between the first arc surface and the card is greater, hence the first arc surface uses a larger radius.

[0046] Understandably, the paddle 220 is a key component in the card transfer device, such as... Figure 2 As shown, the lower end of the paddle 220 is designed with a bushing 222. The function of the bushing 222 is to mount the paddle 220 onto the drive shaft 210, and the bushing 222 is fitted onto the drive shaft 210. A transmission component 211 is provided on the drive shaft 210, and the transmission component 211 is connected to the bushing 222 to drive the paddle 220 to rotate. The connection between the transmission component 211 and the bushing 222 can be direct or achieved through a keyway, spline, or other mechanical indirect methods. For example, the transmission component 211 and the bushing 222 can be connected by a snap-fit ​​structure, screws, pins, etc. When the drive shaft 210 rotates, the transmission component 211 rotates accordingly, and transmits the rotational motion to the paddle 220 through the bushing 222.

[0047] Reference Figure 2 , Figure 7 and Figure 8 In some embodiments of this utility model, the transmission member 211 is provided with a transmission plane 2111. The function of the transmission plane 2111 is to provide a stable contact surface, enabling the transmission member 211 to transmit power to the bushing 222 more effectively. The bushing 222 is provided with a protrusion 2221. The protrusion 2221 not only enhances the structural strength of the bushing 222 but also provides a platform for direct contact with the transmission member 211. The protrusion 2221 is further provided with an abutment plane 2222, which fits tightly with the transmission plane 2111 of the transmission member 211. The cooperation between the abutment plane 2222 and the transmission plane 2111 makes the transmission between the transmission member 211 and the bushing 222 more reliable. Regardless of whether the drive shaft 210 rotates in the forward or reverse direction, it can drive the shaft 210 sleeve and the paddle 220 to rotate, realizing the reset of the paddle and the paddle 220.

[0048] In practical applications, such as Figure 8As shown, when the drive shaft 210 needs to drive the paddle 220 to rotate to push the card, the transmission plane 2111 of the transmission component 211 and the abutment plane 2222 of the protrusion 2221 of the bushing 222 closely cooperate, ensuring effective power transmission and enabling the paddle 220 to rotate smoothly and accurately. As the paddle 220 rotates, its pawl 221 pushes the card through the card-pushing curved surface 2211 until the card is completely disengaged from the pressure roller and enters the card-clamping mechanism 120. Throughout the process, the close cooperation between the transmission component 211 and the bushing 222 ensures the continuity and stability of the card transfer.

[0049] Furthermore, two bushings 222 are designed at the lower end of the paddle 220, distributed on both axial sides of the transmission component 211. This not only enhances the connection strength between the paddle 220 and the transmission component 211 but also ensures the stability and accuracy of the paddle 220 during transmission. With the two bushings 222 located on opposite axial sides of the transmission component 211, the force on the transmission bearing is more evenly distributed during the card-pushing process, which helps improve operational stability.

[0050] Understandably, in the design of a card transfer device, the frame 100 serves as the support and fixing part of the entire device. The frame 100 is typically made of robust metal to ensure its stability and load-bearing capacity. (Refer to...) Figure 1 The vertical adjustment groove 101 is designed to ensure the convenience and accuracy of height adjustment for the upper guide roller 111. The end of the upper guide roller 111 passes through the adjustment groove 101, allowing its height to be adjusted to suit different card thicknesses. A locking element is provided at the end of the upper guide roller 111 to ensure its stability after adjustment. The locking element can be a bolt, nut, or other fastener; tightening it into the appropriate position in the adjustment groove 101 securely fixes the upper guide roller 111 at the desired height. Through the vertical adjustment groove 101 on the frame 100 and the locking element at the end of the upper guide roller 111, the vertical position of the upper guide roller 111 is adjustable and fixed.

[0051] Reference Figure 1In some embodiments of this utility model, a transmission assembly 130 is provided on the outer wall of the frame 100. The transmission assembly 130 includes a driving gear 131, a driven gear 132, and a synchronous belt 133. The outer wall of the frame 100 is designed as a vertical plane to provide a stable mounting base for the transmission assembly 130. The driving gear 131 is mounted on the outer wall of the frame 100 via a rotating shaft and is driven to rotate by a pinion on the output shaft of the motor. The driven gear 132 is fixed to the end of the lower guide roller 112. The synchronous belt 133 serves as a transmission structure connecting the driving gear 131 and the driven gear 132, and has high strength and high wear resistance. The synchronous belt 133 fits tightly against the driving gear 131 and the driven gear 132, transmitting torque through the meshing of the teeth. It is understood that the upper guide roller 111 is not connected to a motor and rotates passively, which already meets the requirements for conveying cards.

[0052] The second aspect of this utility model provides a printer that includes the card transfer device of the first aspect embodiment, encompasses all the technical solutions of the card transfer device, and has all the technical effects of the card transfer device, which will not be repeated here.

[0053] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
