[0003] A card printer is a printing device used to print cards. The process of feeding cards into the printer and feeding cards out of the printer involves pushing cards. With the improvement of printing efficiency, how to achieve automatic and continuous card pushing has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0004] In view of this, the purpose of this application is to provide a card feeding device and a card printer, which aims to solve the technical problem of how to achieve automatic and continuous card feeding.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, embodiments of this application provide a card dispensing device, comprising: The main body has a connected receiving space and an opening, the receiving space being used to stack multiple cards; A card-pushing mechanism is provided at intervals from the opening and includes a first sliding member, a card-pushing member, and a first elastic member. The first sliding member is slidably connected to the body, and the card-pushing member is slidably connected to the first sliding member. The first elastic member is connected to both the first sliding member and the card-pushing member. The card-pushing member has an abutment portion and a first inclined surface. The first inclined surface is located on the side of the abutment portion closer to the opening. Both the abutment portion and the first inclined surface are used to abut against the edge of the bottommost card. A driving mechanism is disposed on the body and connected to the first sliding member. The driving mechanism is used to drive the first sliding member to slide back and forth.

[0006] In some embodiments of the first aspect, the pusher is provided with a chamfered portion located on the side of the abutment portion away from the opening.

[0007] In some embodiments of the first aspect, the chamfered portion includes an arc surface and a second bevel, the second bevel being smoothly connected to the side of the arc surface away from the abutment portion.

[0008] In some embodiments of the first aspect, the pusher is provided with a first limiting portion and the first slider is provided with a second limiting portion; when the first elastic member drives the pusher to slide along the direction close to the receiving space to a preset position, the first limiting portion abuts against the second limiting portion.

[0009] In some embodiments of the first aspect, the drive mechanism includes: The transmission assembly includes a second slider, a first connecting rod, a third slider, and a second connecting rod. The first connecting rod is rotatably connected to the body and is provided with a first guide hole and a second guide hole. The second slider passes through the first guide hole and is connected to the first slider. The third slider passes through the second guide hole and is connected to one side of the second connecting rod. A driving member is disposed on the body and connected to the side of the second link away from the third sliding member. The driving member is used to drive the second link to rotate.

[0010] In some embodiments of the first aspect, the card feeding device further includes a photoelectric sensor and a sensing lever. The photoelectric sensor is disposed on the body, and the sensing lever is connected to the body. One side of the sensing lever is used to abut against the large surface of the card located at the bottom, and the other side is used to trigger the photoelectric sensor. Both the photoelectric sensor and the driving mechanism are electrically connected to the mainboard of the card printer.

[0011] In some embodiments of the first aspect, the card feeding device further includes a guiding mechanism comprising a plurality of first guide wheels, second guide wheels, and a connector, each of the first guide wheels being rotatably connected to the body, the connector being slidably connected to the body, and the second guide wheels being rotatably connected to the connector, wherein one of the first guide wheels and the second guide wheels defines a slit communicating with the opening, the slit being for passing the card through.

[0012] In some embodiments of the first aspect, the guide mechanism further includes a movable shaft, a second elastic element, and a rotating disk. The second elastic element is connected to the connector and the body respectively. The rotating disk is rotatably connected to the body and has an arc-shaped hole. The arc-shaped hole is eccentrically disposed with respect to the rotating disk. The movable shaft is connected to the connector and passes through the arc-shaped hole. The movable shaft and the arc-shaped hole are clearance-fitted.

[0013] In some embodiments of the first aspect, the card feeding device further includes a counterweight located within the receiving space, the counterweight being used to place the uppermost card.

[0015] The beneficial effects of this application are as follows: When using the card feeding device provided in this application, the drive mechanism drives the first slider to slide in the direction close to the opening, thereby causing the card pusher to move in the direction close to the opening until the first inclined surface abuts against the edge of the bottommost card. At this time, the card moves the first slider away from the receiving space through the first inclined surface, causing the first elastic element to store elastic potential energy until the abutting part abuts against the edge of the card. As the card pusher continues to move in the direction close to the opening, the card is pushed into the opening. Then, the drive mechanism drives the first slider to slide in the direction away from the opening, thereby causing the card pusher to move in the direction away from the opening. At the same time, the elastic potential energy of the first elastic element is released, thereby causing the first slider to slide in the direction close to the receiving space, thereby causing the card pusher to avoid the card and reset. By repeating the above action process, the card can be automatically and continuously pushed, which helps to improve the printing efficiency of the card printer.

[0020] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0023] In the description of this application, the terms "first," "second," etc., are used to distinguish different objects and should not be construed as indicating or implying a specific order or hierarchy, or implicitly specifying the number of technical features indicated. Therefore, a feature marked "first" or "second" may explicitly or implicitly include one or more of that feature.

[0027] A card printer is a printing device used to print cards (such as ID cards, driver's licenses, bank cards, membership cards, event tickets, postcards, etc., without specific limitations). The process of inputting cards into the printer and outputting cards from the printer involves pushing the cards. With the improvement of printing efficiency, how to achieve automatic and continuous card pushing has become a technical problem that urgently needs to be solved in this field.

[0028] like Figure 1 As shown, in order to solve the above-mentioned technical problems, the embodiments of this application provide a card feeding device 100, which relates to the field of printing equipment technology and is mainly used in card printers. Of course, it can also be used in card making equipment, and no specific limitation is made here.

[0029] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the card feeding device 100 provided in this embodiment includes: a body 110, a card pushing mechanism 120, and a driving mechanism 130.

[0030] The main body 110 has a connected receiving space 111 and an opening 112. The receiving space 111 is used to stack multiple cards 200. The card pushing mechanism 120 is spaced apart from the opening 112 and includes a first sliding member 121, a card pushing member 122 and a first elastic member 123. The first sliding member 121 is slidably connected to the main body 110, and the card pushing member 122 is slidably connected to the first sliding member 121. The first elastic member 123 is connected to the first sliding member 121 and the card pushing member 122 respectively. The card pushing member 122 has an abutment portion 1221 and a first inclined surface 1223. The first inclined surface 1223 is located on the side of the abutment portion 1221 near the opening 112. Both the abutment portion 1221 and the first inclined surface 1223 are used to abut against the edge of the bottommost card 200. The driving mechanism 130 is disposed on the main body 110 and connected to the first sliding member 121. The driving mechanism 130 is used to drive the first sliding member 121 to slide back and forth.

[0031] It should be noted that "the pusher 122 is slidably connected to the first slider 121" can be understood as: the pusher 122 can slide relative to the first slider 121 in a direction away from the receiving space 111 (i.e., downward) and in a direction close to the receiving space 111 (i.e., upward). "The first slider 121 is slidably connected to the body 110" can be understood as: the first slider 121 can slide relative to the body 110 in a direction close to the opening 112 and in a direction away from the opening 112. It can be understood that the sliding direction of the pusher 122 and the sliding direction of the first slider 121 are perpendicular to each other.

[0032] Furthermore, "the drive mechanism 130 is used to drive the first slider 121 to slide back and forth" can be understood as: the drive mechanism 130 can drive the first slider 121 to slide alternately along the direction close to the opening 112 and along the direction away from the opening 112.

[0033] It is understood that when using the card feeding device 100 provided in this embodiment, the driving mechanism 130 drives the first sliding member 121 to slide in the direction close to the opening 112, so as to drive the card pusher 122 to move in the direction close to the opening 112 until the first inclined surface 1223 abuts against the edge of the bottommost card 200. At this time, the card 200 drives the first sliding member 121 to slide in the direction away from the receiving space 111 through the first inclined surface 1223, so that the first elastic member 123 stores elastic potential energy until the abutting part 1221 abuts against the edge of the card 200. As the card pusher 122 continues to move in the direction close to the opening 112, the card 200 is pushed into the opening 112 (e.g., Figure 6 and Figure 7 (As shown); Next, the drive mechanism 130 drives the first slider 121 to slide in a direction away from the opening 112, so as to drive the pusher 122 to move in a direction away from the opening 112. At the same time, the elastic potential energy of the first elastic member 123 is released, so as to drive the first slider 121 to slide in a direction closer to the receiving space 111, thereby realizing that the pusher 122 avoids the card 200 and resets (as shown). Figure 1 and Figure 2 As shown in the figure, by repeating the above process, the card 200 can be automatically and continuously pushed, which helps to improve the printing efficiency of the card printer.

[0034] It should be noted that when the card feeding device 100 is applied to a card printer, it can be used both during the process of inputting cards 200 into the card printer, i.e., when multiple unprinted cards 200 are stacked in the receiving space 111, and during the process of outputting cards 200 from the card printer, i.e., when multiple printed cards 200 are stacked in the receiving space 111. No specific limitations are made on the application scenarios of the card feeding device 100 in the card printer.

[0035] like Figures 7 to 9 As shown, in some embodiments, the pusher 122 is provided with a chamfered portion 1222, which is located on the side of the abutment portion 1221 away from the opening 112. In this way, when the drive mechanism 130 drives the first slider 121 to slide in a direction away from the opening 112, the pusher 122 can more smoothly avoid the card 200 and reset, reducing the possibility of structural interference.

[0036] like Figure 9 As shown, the chamfered portion 1222 further includes an arc surface 12221 and a second inclined surface 12222, the second inclined surface 12222 being smoothly connected to the side of the arc surface 12221 away from the abutment portion 1221.

[0037] Understandably, the combination of the curved surface 12221 and the second inclined surface 12222 can not only improve structural interference, but also reduce the risk of damaging the card 200 during the process of the pusher 122 avoiding the card 200 and resetting.

[0038] Of course, for the above embodiments, the chamfered portion 1222 can be only the arc surface 12221, or the chamfered portion 1222 can be only the second inclined surface 12222. That is, using the arc surface 12221 alone or the first inclined surface 1223 alone can achieve the goal of improving the structural interference and card 200 damage.

[0039] like Figure 8 and Figure 9 As shown, in some embodiments, the pusher 122 is provided with a first limiting part 1224, and the first sliding member 121 is provided with a second limiting part 1211; when the first elastic member 123 drives the pusher 122 to slide to a preset position along the direction close to the receiving space 111, the first limiting part 1224 abuts against the second limiting part 1211.

[0040] It should be noted that, Figure 2 The position of the push card member 122 relative to the first slider 121 shown is the aforementioned preset position. This preset position can be set according to design needs, such as being higher than the thickness of one card 200, or higher than half the thickness of one card 200, or higher than the thickness of two cards 200. No specific limitation is made here.

[0041] Understandably, during the process of the drive mechanism 130 driving the first sliding member 121 to slide in a direction away from the opening 112, the elastic potential energy of the first elastic member 123 is released, thereby driving the push card member 122 to slide in a direction close to the receiving space 111 until it reaches the preset position. At this point, the first limiting part 1224 abuts against the second limiting part 1211 to restrict the push card member 122 from continuing to move. This achieves the limiting effect, thereby enhancing the reliability of the push card mechanism 120.

[0042] like Figures 4 to 7 As shown, in some embodiments, the drive mechanism 130 includes a transmission assembly 131 and a drive member 132. The transmission assembly 131 includes a second sliding member 1311, a first connecting rod 1312, a third sliding member 1313, and a second connecting rod 1314. The first connecting rod 1312 is rotatably connected to the body 110 and is provided with a first guide hole 13121 and a second guide hole 13122. The second sliding member 1311 passes through the first guide hole 13121 and is connected to the first sliding member 121. The third sliding member 1313 passes through the second guide hole 13122 and is connected to one side of the second connecting rod 1314. The drive member 132 is disposed on the body 110 and is connected to the side of the second connecting rod 1314 away from the third sliding member 1313. The drive member 132 is used to drive the second connecting rod 1314 to rotate.

[0043] For example, the drive unit 132 can be selected from a rotary motor, drive motor, servo motor, etc., without specific limitations.

[0044] Understandably, the drive member 132 can drive the second link 1314 to rotate, thereby driving the first link 1312 to rotate through the third slider 1313. This, in turn, drives the first slider 121 to slide through the second slider 1311. By using the cooperation between the second slider 1311 and the first guide hole 13121, and the cooperation between the third slider 1313 and the second guide hole 13122, the rotational motion output by the drive member 132 is converted into the linear reciprocating motion of the first slider 121. This structural design not only drives the reciprocating sliding of the first slider 121, but also makes the drive mechanism 130 occupy less space and has a more compact structure, thus contributing to the miniaturization design of the card printer.

[0045] In another embodiment, the drive mechanism 130 includes a drive member 132, a transmission gear, and a rack. The drive member 132 is disposed on the body 110 and connected to the transmission gear. The rack is connected to the first sliding member 121 and meshes with the transmission gear. The drive member 132 drives the transmission gear to rotate in a first rotation direction, which can drive the rack and the first sliding member 121 to slide in a direction close to the opening 112. The drive member 132 drives the transmission gear to rotate in a second rotation direction opposite to the first rotation direction, which can drive the rack and the first sliding member 121 to slide in a direction away from the opening 112. In this way, the reciprocating sliding of the first sliding member 121 can also be driven.

[0046] In some other embodiments, the drive mechanism 130 may also be a linear motor. The linear motor is connected to the first slider 121 and can also drive the first slider 121 to slide back and forth. The structure of the drive mechanism 130 is not specifically limited here.

[0047] like Figure 6 , Figure 7 and Figure 10 As shown, in some embodiments, the card feeding device 100 further includes a photoelectric sensor 141 and a sensing lever 142. The photoelectric sensor 141 is disposed on the body 110, and the sensing lever 142 is connected to the body 110. One side of the sensing lever 142 is used to abut against the large surface of the card 200 located at the bottom, and the other side is used to trigger the photoelectric sensor 141. The photoelectric sensor 141 and the drive mechanism 130 are both electrically connected to the main board of the card printer.

[0048] It should be noted that the photoelectric sensor 141 has a U-shaped groove, with a light emitter on one side and a light receiver on the other side. The position of the sensing arm 142 is detected by whether the light path between the light emitter and the light receiver is blocked by the sensing arm 142.

[0049] Understandably, the above design can detect whether all the cards 200 in the storage space 111 have been pushed out, thereby helping to improve the automation level of the card printer.

[0050] Specifically, when all cards 200 are pushed (i.e., there are no cards 200 in the receiving space 111), one side of the sensing lever 142 loses the support of the large surface of the last card 200, and the light path of the photoelectric sensor 141 is blocked by the other side of the sensing lever 142. That is, the sensing lever 142 triggers the photoelectric sensor 141. At this time, the main board of the card printer receives the signal from the photoelectric sensor 141 and controls the drive mechanism 130 to stop running. When not all cards 200 are pushed (i.e., there are cards 200 in the receiving space 111), the large surface of the bottom card 200 abuts against one side of the sensing lever 142. At this time, the light path of the photoelectric sensor 141 is not blocked by the other side of the sensing lever 142. That is, the sensing lever 142 does not trigger the photoelectric sensor 141. At this time, the main board of the card printer does not need to control the drive mechanism 130 to stop running.

[0051] It should be noted that when the drive mechanism 130 includes the drive element 132, the mainboard of the card printer is electrically connected to the photoelectric sensor 141 and the drive element 132 respectively.

[0052] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, in some embodiments, the card feeding device 100 further includes a guide mechanism 150, which includes a plurality of first guide wheels 151, second guide wheels 152 and connectors 153. Each first guide wheel 151 is rotatably connected to the body 110, the connector 153 is slidably connected to the body 110, and the second guide wheel 152 is rotatably connected to the connector 153. One of the first guide wheels 151 and the second guide wheel 152 defines a slit 113 communicating with the opening 112. The slit 113 is used to pass the card 200 through.

[0053] For example, the number of first guide wheels 151 can be two, three, four, five, etc., without any specific limitation here.

[0054] It is understandable that the first guide wheel 151 and the second guide wheel 152 can support the large surface of the card 200 and guide the movement of the card 200, thereby reducing the possibility of the card 200 shifting or tilting, making the card pushing process more stable and reliable, and thus reducing the risk of the card feeding device 100 malfunctioning.

[0055] like Figure 1 and Figure 3 As shown, the guide mechanism 150 further includes a movable shaft 154, a second elastic element 155, and a rotating disk 156. The second elastic element 155 is connected to the connector 153 and the main body 110 respectively. The rotating disk 156 is rotatably connected to the main body 110 and is provided with an arc hole 1561. The arc hole 1561 is eccentrically arranged with the rotating disk 156. The movable shaft 154 is connected to the connector 153 and passes through the arc hole 1561. The movable shaft 154 and the arc hole 1561 are clearance-fitted.

[0056] For example, the first elastic element 123 and / or the second elastic element 155 may be selected from elements with elastic stretching capabilities such as springs, sheet springs, and elastic silicone, without specific limitations.

[0057] It should be noted that "the eccentric setting of the arc hole 1561 and the rotating disk 156" can be understood as: the center of the rotating disk 156 and the center of the corresponding arc hole 1561 do not coincide. "The clearance fit between the movable shaft 154 and the arc hole 1561" can be understood as: there is a clearance between the outer circumference of the movable shaft 154 and the upper wall of the arc hole 1561, which allows the movable shaft 154 to move up and down relative to the rotating disk 156.

[0058] Understandably, by rotating the disc 156, guided by the eccentrically set arc hole 1561, the movable shaft 154 can drive the second guide wheel 152 connected to the connector 153 to move up or down, thereby adjusting the position of the slit 113 to allow the thickness of the card 200 to pass through, so that the card feeding device 100 can push cards 200 of different thicknesses, thus having higher compatibility.

[0059] like Figure 1 and Figure 2 As shown, in some embodiments, the card feeding device 100 further includes a counterweight 143 located in the receiving space 111. The counterweight 143 is used to place on the uppermost card 200. In this way, when the number of cards 200 in the receiving space 111 is small, the possibility of the card 200 shifting is reduced, so that the card 200 can be tightly engaged with the abutment portion 1221 and the first inclined surface 1223 of the card pusher 122, thereby reducing the risk of the card 200 falling off the card pusher 122 and causing a failure in the card pushing process.
