Description

Technical Field

[0001] This utility model relates to the field of printer technology, and in particular to an auxiliary feeding mechanism. Background Technology

[0002] To automate card printing, existing card printer systems typically consist of a printer and a card storage box. The printer usually has a notch on its top side edge, with vertical and horizontal surfaces perpendicular to each other. The horizontal surface has a raised drive roller, while the bottom of the vertical surface has a feed inlet aligned with the upper surface of the drive roller. The card storage box is installed at the notch and is used to stack multiple cards. The bottom of the card storage box has an opening through which the bottom card is placed onto the drive roller. By limiting the height of the feed inlet to be greater than the thickness of one card but less than the thickness of two cards, the drive roller rotates, thus driving the bottom card into the printer for printing.

[0003] However, due to limitations in the size of the notch and the printer's own weighing capacity, the card storage box has a limited volume, and the number of cards stored at one time cannot meet the requirements of large-volume card printing. Therefore, in actual production, it is considered to expand the capacity of the existing card storage mechanism.

[0004] However, existing card storage mechanisms can only output cards from their outlets. The output cards can only continue to move forward along the horizontal direction of the notch and enter the feed port under the drive of the transmission rollers. At this time, the lack of a limiting structure causes the cards to easily shift position on the surface of the transmission rollers, which in turn affects the alignment accuracy of subsequent printing. Utility Model Content

[0005] The main purpose of this invention is to propose an auxiliary feeding mechanism to solve the problem of card position deviation during the feeding process.

[0006] To achieve the above objectives, this utility model proposes an auxiliary feeding mechanism that can be installed at the notch of a printer. The notch has a vertical surface and a horizontal surface that are perpendicular to each other. The horizontal surface is provided with a transmission roller protruding from the horizontal surface, and the vertical surface is provided with a feeding port aligned with the top of the transmission roller. The auxiliary feeding mechanism includes: A base, the bottom of which forms a rotation space; and A feed roller is rotatably mounted on the base and located within the rotation space; When the base is installed at the notch, the two ends of the rotation space are respectively connected to the feed port and the discharge port of the card storage mechanism. The feed roller cooperates with the transmission roller to clamp the opposite sides of the card.

[0007] In one embodiment, the feed roller is elastically connected to the base; When the base is installed at the notch, the two ends of the rotation space (1212) are respectively connected to the feed port and the discharge port of the storage mechanism, and the feed roller can move relative to the transmission roller.

[0008] In one embodiment, the base has rotating holes on opposite sides, and the auxiliary feeding mechanism further includes: A rotating shaft, which movably passes through the two rotating holes and is capable of moving vertically within the rotating holes, and a feed roller is sleeved on the rotating shaft; and A first elastic element has its two ends connected to the rotating shaft and the base, respectively. The first elastic element is used to allow the rotating shaft to move and then reset.

[0009] In one embodiment, the base includes: Support plate; and A floating frame, which is elastically connected to the support plate, and the bottom of the floating frame forms the rotation space; When the base is installed in the notch, the support plate is at least partially supported on the top of the vertical surface, and the floating frame is movable relative to the horizontal surface so that the bottom of the floating frame is supported on the horizontal surface.

[0010] In one embodiment, the support plate has a first through hole, the floating frame has a second through hole corresponding to the first through hole, and the auxiliary feeding mechanism further includes: The movable rod, one end of which is disposed on the floating frame, and the other end of which passes sequentially through the second through hole and the first through hole; and The second elastic element is sleeved on the movable rod and passes through the first through hole. The second elastic element is limited and abuts against the inner wall of the first through hole.

[0011] In one embodiment, the floating frame includes: A support base, wherein the bottom of the support base forms the rotation space, and the top of the support base has the second through hole; and A movable plate, one end of which is hinged to the support base and located on top of the support base, with a gap between the movable plate and the top of the support base to form an movable space, the support plate, the movable rod and the second elastic element being located within the movable space; When the base is installed in the notch, the end of the second elastic member away from the second through hole abuts against the movable plate.

[0012] In one embodiment, the support plate includes a vertical part and a horizontal part connected to each other. One end of the horizontal part is inserted into the movable space, and the portion of the horizontal part located in the movable space has the first through hole. The other end of the horizontal part protrudes from the plane where the side wall of the support base is located, and is used to support the top of the vertical surface. The vertical part is perpendicular to the horizontal part and is located at the end of the horizontal part that faces away from the active space. The side of the vertical part that faces away from the horizontal part can abut against the side wall of the printer.

[0013] In one embodiment, the extension direction of the first through hole is consistent with the length direction of the horizontal portion; The support plate is movable relative to the movable rod along the extension direction of the first through hole, so that the vertical part is limited to abutting against the side wall of the printer.

[0014] In one embodiment, the movable rod includes a connecting part and a limiting part. The connecting part passes through the first through hole and the second through hole in sequence. The limiting part is sleeved on the end of the connecting part facing away from the support base, and the size of the limiting part is larger than the size of the first through hole. The limiting part is used to limit the movement of the support plate.

[0015] In one embodiment, the movable rod and the second elastic element are each comprised of a plurality of them, and the plurality of movable rods and the plurality of second elastic elements are symmetrically arranged on the support plate.

[0016] The technical solution of this utility model involves installing a base at the notch of the printer and setting a feeding roller at the bottom of the base, so that the feeding roller and the printer's drive roller cooperate with each other. During operation, the card storage mechanism feeds the card horizontally, and the front end of the card contacts the drive roller. The printer drives the drive roller to rotate actively, and the surface of the drive roller contacts the bottom surface of the card, generating friction and directly pushing the card towards the feed port. At the same time, the upper surface of the card abuts against the feeding roller, and the reverse friction generated by the card's forward movement drives the feeding roller to rotate synchronously. The feeding roller and the drive roller cooperate to hold the card, thus providing continuous power for feeding through the drive roller and forming a limiting constraint through the cooperation of the feeding roller, ensuring that the card is transported along a straight trajectory during the feeding stage and preventing deviation.

[0024] To automate card printing, existing card printer systems typically consist of a printer and a card storage box. The printer usually has a notch on its top side edge, with vertical and horizontal surfaces perpendicular to each other. The horizontal surface has a raised drive roller, while the bottom of the vertical surface has a feed inlet aligned with the upper surface of the drive roller. The card storage box is installed at the notch and is used to stack multiple cards. The bottom of the card storage box has an opening through which the bottom card is placed onto the drive roller. By limiting the height of the feed inlet to be greater than the thickness of one card but less than the thickness of two cards, the drive roller rotates, thus driving the bottom card into the printer for printing.

[0025] However, due to limitations in the size of the notch and the printer's own weighing capacity, the card storage box has a limited volume, and the number of cards stored at one time cannot meet the requirements of large-volume card printing. Therefore, in actual production, it is considered to expand the capacity of the existing card storage mechanism.

[0026] However, existing card storage mechanisms can only output cards from their outlets. The output cards can only continue to move forward along the horizontal direction of the notch and enter the feed port under the drive of the transmission rollers. At this time, the lack of a limiting structure causes the cards to easily shift position on the surface of the transmission rollers, which in turn affects the alignment accuracy of subsequent printing.

[0027] This utility model proposes an auxiliary feeding mechanism 100, which aims to solve the problem that the card is prone to positional deviation during the feeding process.

[0028] Please see Figures 1 to 4In one embodiment of this utility model, the auxiliary feeding mechanism 100 includes a base 1 and a feeding roller 2. A rotation space 1212 is formed at the bottom of the base 1. The feeding roller 2 is rotatably disposed on the base 1 and located within the rotation space 1212. When the base 1 is installed at the notch, the two ends of the rotation space 1212 are respectively connected to the feed port and the discharge port of the card storage mechanism. The feeding roller 2 cooperates with the transmission roller to clamp the opposite sides of the card.

[0029] In this embodiment, the base 1 serves as the structural foundation of the auxiliary feeding mechanism 100. Its bottom is recessed or hollowed out to form a rotating space 1212. The feeding roller 2 is rotatably mounted on the base 1 through a rotating shaft or bearing structure and housed inside the rotating space 1212. The rotation axis of the feeding roller 2 is parallel to the rotation axis of the printer drive roller.

[0030] Understandably, this solution involves mounting the base 1 at the notch of the printer and placing a feed roller 2 at the bottom of the base 1, allowing the feed roller 2 to cooperate with the printer's drive roller. During operation, the printer drives the drive roller to rotate actively. The surface of the drive roller contacts the bottom surface of the card, generating friction that directly pushes the card towards the feed inlet. Simultaneously, the upper surface of the card abuts against the feed roller 2, and the reverse friction generated by the card's forward movement drives the feed roller 2 to rotate synchronously. The feed roller 2 and the drive roller cooperate vertically to hold the card. This provides continuous power for feeding through the drive roller and also creates a limiting constraint through the cooperation of the feed roller 2, ensuring that the card is transported along a straight trajectory during the feeding stage and preventing deviation.

[0031] It should be noted that in this embodiment, the feed roller 2 itself is not actively driven; instead, it is driven by the transmission roller to rotate synchronously with the transmission roller. This configuration results in a simple structure and good synchronization between the two. Alternatively, a driving component can be additionally provided on the base 1 to directly drive the feed roller 2 to rotate.

[0032] In this embodiment, a limiting wheel (unlabeled) is installed on the side of the base 1 facing the card storage mechanism. The limiting wheel can rotate around its own axis, and the direction of rotation is consistent with the direction of card movement. When a card is output from the outlet of the card storage mechanism, the front end of the card will first contact the limiting wheel. The limiting wheel provides limiting support for the card, preventing it from tilting and ensuring that the card enters between the transmission roller and the feeding roller 2 at a stable angle. Alternatively, a rotating wheel can be installed on the card storage mechanism. After the card storage mechanism is connected to the base 1, the rotating wheel and the limiting wheel are aligned vertically. The card in the card storage mechanism is output under the drive of the rotating wheel. At this time, the rotating wheel and the limiting wheel simultaneously clamp the opposite sides of the card to ensure the stability of the card during output.

[0033] Furthermore, the connection method between the card storage mechanism and the base 1 is not specifically limited here. A corresponding groove can be provided on the base 1, allowing the card storage mechanism to be inserted into the groove, thus ensuring the stability of the connection. Alternatively, magnetic components can be provided at corresponding positions to ensure connection stability through magnetic attraction. Regardless of the configuration, it must be ensured that the cards output from the outlet of the card storage mechanism can enter between the transmission roller and the feed roller 2 at a relatively stable angle.

[0034] Optionally, the feed roller 2 can be a rubber roller, a silicone roller, or a polyurethane roller. Additionally, the surface of the feed roller 2 can be knurled or grooved to increase the coefficient of friction.

[0035] In existing technology, due to differences in the size of the drive rollers and the thickness of the cards among different printers, as well as assembly errors, the distance between the drive roller and the feed roller 2 when installing the auxiliary feeding mechanism 100 does not meet the actual requirements. The distance may be too large, making it impossible to clamp the sides of the card and provide a limiting function. Alternatively, the distance may be too small, even causing them to abut each other, making it impossible to insert the card at all.

[0036] To resolve the above issues, please refer to Figure 1 and Figure 4 In one embodiment, the feed roller 2 is elastically connected to the base 1. When the base 1 is installed in the notch, the feed roller 2 can move relative to the drive roller.

[0037] Understandably, when the base 1 is installed in the notch, the feed roller 2 can automatically adjust its vertical position according to the actual thickness of the card and the position of the drive roller, thus forming an adaptive clamping mechanism. Specifically, when no card is inserted, the feed roller 2 is at its lowest point under the influence of gravity, basically flush with the bottom of the base 1. When the base 1 is installed in the notch, the drive roller protruding from the horizontal surface can lift the feed roller 2, thus making the drive roller and the feed roller 2 fit tightly together. When a card is inserted, the card can lift the feed roller 2 up a further height to accommodate the thickness of the card.

[0038] In one implementation, please refer to Figure 4 The base 1 has rotating holes 1211 on its opposite sides. The auxiliary feeding mechanism 100 also includes a rotating shaft 3 and a first elastic member 4. The rotating shaft 3 is movably inserted through the two rotating holes 1211 and can move vertically within the rotating holes 1211. The feeding roller 2 is sleeved on the rotating shaft 3. The two ends of the first elastic member 4 are connected to the rotating shaft 3 and the base 1 respectively. The first elastic member 4 is used to reset the rotating shaft 3 after it moves.

[0039] In this embodiment, rotating holes 1211 are respectively provided on the opposite side walls of the base 1. The rotating holes 1211 are elongated holes that extend vertically, allowing the rotating shaft 3 to slide vertically within the rotating holes 1211. At this time, the outer diameter of the portion of the rotating shaft 3 located inside the rotating holes 1211 is slightly smaller than the size of the rotating holes 1211 to ensure the movement of the rotating shaft 3. Meanwhile, the feed roller 2 is mounted on the rotating shaft 3 via bearings. The first elastic element 4 is a torsion spring, one end of which is wound around the rotating shaft 3, and the other end of which is hooked onto the base 1 through a hole.

[0040] In the initial state, the torsion spring is not subjected to upward pressure. Under the action of the torsion spring and the gravity of the rotating shaft 3 itself, the rotating shaft 3 is located at the bottom of the rotating hole 1211. Once the feed roller 2 contacts the transmission roller or card, the transmission shaft is subjected to upward pressure and moves upward, thereby driving the torsion spring to rotate and compress, storing elastic potential energy. Once the auxiliary feeding mechanism 100 is disassembled, the torsion spring releases its elastic potential energy, thereby allowing the rotating shaft 3 to quickly return to its original position.

[0041] Optionally, the rotating hole 1211 can be an oblong hole. At the same time, limit springs, baffles or nuts can be provided at both ends of the rotating shaft 3 to prevent the rotating shaft 3 from falling off the base 1 along the axial direction.

[0042] In another embodiment, only the first elastic element 4 can be provided. In this case, the first elastic element 4 is a spring, with its two ends abutting against the rotating shaft 3 and the base 1, respectively. When the rotating shaft 3 moves upward, the spring will be compressed. Furthermore, the spring can also be directly set in the rotating hole 1211, with its two ends abutting against the inner wall of the rotating hole 1211 and the rotating shaft 3, respectively.

[0043] In existing technologies, the vertical height of the notch varies among different printers. When the top of the base 1 is supported by the top of the vertical surface, the vertical surface is too high, and the bottom of the base 1 may be suspended in mid-air, making it impossible to ensure that the base 1 is stably installed on the printer. Alternatively, if the vertical surface is too low, when the bottom of the base 1 is supported by the horizontal surface, there will be a distance between the top of the base 1 and the top of the vertical surface, again making it impossible to ensure that the base 1 is stably installed on the printer.

[0044] To resolve the above issues, please refer to Figure 1 , Figure 2 and Figure 3 In one embodiment, the base 1 includes a support plate 11 and a floating frame 12, the floating frame 12 being elastically connected to the support plate 11, and a rotation space 1212 being formed at the bottom of the floating frame 12. When the base 1 is installed in the notch, the support plate 11 is at least partially supported on the top of the vertical surface, and the floating frame 12 can move relative to the horizontal surface so that the bottom of the floating frame 12 is supported on the horizontal surface.

[0045] Understandably, the support plate 11, as the upper positioning component, at least partially overlaps the top of the vertical plane, providing initial positioning. The floating frame 12, as the lower load-bearing component, has a rotation space 1212 at its bottom, which allows it to float up and down relative to the support plate 11 within the elastic connection range, thereby automatically adapting to the height of the vertical plane. Ultimately, the bottom of the floating frame 12 is stably attached to the horizontal plane, achieving two-point support and ensuring the overall stability of the base 1.

[0046] Optionally, the elastic connection can be a spring connection, a spring sheet connection, a rubber block connection, or an airbag connection. Meanwhile, a guide structure, such as a guide post and guide sleeve or a slide rail and slider, can be provided between the support plate 11 and the floating frame 12 to ensure that the floating frame 12 rises and falls vertically without tilting. These structures are common in the prior art and will not be described in detail here.

[0047] In one implementation, please refer to Figure 2 and Figure 3 The support plate 11 has a first through hole 111, and the floating frame 12 has a second through hole 1213 corresponding to the first through hole 111. The auxiliary feeding mechanism 100 also includes a movable rod 5 and a second elastic member 6. One end of the movable rod 5 is located on the floating frame 12, and the other end of the movable rod 5 passes through the second through hole 1213 and the first through hole 111 in sequence. The second elastic member 6 is sleeved on the movable rod 5 and passes through the first through hole 111. The second elastic member 6 is limited and abuts against the inner wall of the first through hole 111.

[0048] Specifically, the support plate 11 has a first through hole 111, and the floating frame 12 has a second through hole 1213 corresponding to the first through hole 111. The two through holes are at least partially aligned to provide an installation channel for the movable rod 5. The movable rod 5 serves as a guide structure, with one end fixed to the floating frame 12 and the other end passing through the second through hole 1213 and the first through hole 111 in sequence. The second elastic element 6 is a spring, sleeved on the outer periphery of the movable rod 5 and passing through the first through hole 111. The outer wall of the second elastic element 6 is in limiting contact with the inner wall of the first through hole 111, so that the second elastic element 6 cannot arbitrarily disengage from the first through hole 111.

[0049] Understandably, with this configuration, the elastic force of the second elastic element 6 is transmitted to the support plate 11 and the floating frame 12 through the axial guidance of the movable rod 5. The compression or tension of the second elastic element 6 drives the floating frame 12 to float relative to the support plate 11. At the same time, the movable rod 5 constrains the floating direction, allowing only vertical displacement to prevent skewing.

[0050] Optionally, the limiting contact between the second elastic element 6 and the first through hole 111 can be an interference fit, a slot positioning, or a step limiting. Meanwhile, optionally, the connection between the movable rod 5 and the float can be a threaded connection, a press-fit connection, or an integral molding.

[0051] Further, please refer to Figure 2 and Figure 3 The movable rod 5 and the second elastic element 6 each include multiple ones, and the multiple movable rods 5 and the multiple second elastic elements 6 are symmetrically arranged on the support plate 11.

[0052] In this embodiment, four movable rods 5 are symmetrically arranged on opposite sides of the support plate 11, forming a rectangular structure to ensure stability during floating motion. Similarly, four second elastic elements 6 are also included, each of which is sleeved on one movable rod 5.

[0053] Optionally, the number of movable rods 5 can also be set to two, three, or five, etc., without specific limitation. It should be noted that when the number is odd, an odd number of movable rods 5 can be set at the central axis position of the support plate 11, and the remaining movable rods 5 are symmetrically arranged on opposite sides of the support plate 11.

[0054] In the prior art, due to manufacturing errors and other processing requirements, the angle between the vertical and horizontal planes at the notch of different printers is not completely perpendicular. When the auxiliary feeding mechanism 100 is supported on the top of the vertical plane, the auxiliary feeding mechanism 100 cannot be fully fitted to the vertical plane, lacking support and affecting the stability of the installation.

[0055] To resolve the above issues, please refer to Figure 2 and Figure 3 In one embodiment, the floating frame 12 includes a support base 121 and a movable plate 122. The bottom of the support base 121 forms a rotation space 1212, and the top of the support base 121 has a second through hole 1213. One end of the movable plate 122 is hinged to the support base 121 and located at the top of the support base 121. A gap is provided between the movable plate 122 and the top of the support base 121 to form a movable space 1221. The support plate 11, the movable rod 5, and the second elastic member 6 are located within the movable space 1221. When the base 1 is installed at the notch, the end of the second elastic member 6 away from the second through hole 1213 abuts against the movable plate 122.

[0056] In this embodiment, the support base 121 serves as the rigid base of the floating frame 12. The bottom of the support base 121 has a rotation space 1212, and the top has a second through hole 1213. The movable plate 122 serves as the elastic force-bearing component of the floating frame 12. One end of the movable plate 122 is hinged to the top of the support base 121, allowing it to rotate relative to the support base 121. The movable plate 122 and the top of the support base 121 together form the movable space 1221. The top of the second elastic member 6 abuts against the lower surface of the movable plate 122, and the bottom passes through the second through hole 1213 and abuts against the support base 121.

[0057] When the base 1 is installed in the notch of the printer, the end of the movable plate 122 facing away from the hinge position will abut against the printer limit. At this time, the card storage mechanism is attached to the side of the support base 121 facing away from the printer. Pushing the card storage mechanism toward the printer causes the support base 121 to rotate around the hinge position, so that the other side of the support base 121 is attached to the vertical surface of the notch, avoiding wear caused by lateral force.

[0058] It should be noted that the hinge rotation at this time is a fine adjustment within a small angle range. With the cooperation of the first elastic element 4 and the second elastic element 6, the bottom of the support seat 121 is still supported on the horizontal plane of the notch.

[0059] In one implementation, please refer to Figure 2 and Figure 3 The support plate 11 includes a vertical part 113 and a horizontal part 112 connected to each other. One end of the horizontal part 112 is inserted into the movable space 1221, and the portion of the horizontal part 112 located in the movable space 1221 has a first through hole 111. The other end of the horizontal part 112 protrudes from the plane of the side wall of the support base 121 and is used to support the top of the vertical surface. The vertical part 113 is perpendicular to the horizontal part 112 and is located at the end of the horizontal part 112 facing away from the movable space 1221. The side of the vertical part 113 facing away from the horizontal part 112 can be limited and abutted against the side wall of the printer.

[0060] In this embodiment, the support plate 11 adopts an L-shaped bending structure. The horizontal part 112 serves as the main load-bearing section. One end of the horizontal part 112 is inserted into the movable space 1221 and has a first through hole 111. The other end of the horizontal part 112 extends outward and protrudes from the side wall of the support base 121, forming a cantilever support structure. The protruding part directly overlaps the top of the vertical surface of the notch. The vertical part 113 serves as a lateral limiting section and is set at an angle to the horizontal part 112, usually 90° or slightly greater than 90°. It is located at the end of the horizontal part 112 facing away from the movable space 1221, and its side facing away from the horizontal part 112 can form a limiting abutment with the side wall of the printer.

[0061] Understandably, the horizontal part 112 can achieve vertical support and positioning, while the vertical part 113 can achieve lateral limitation in the horizontal direction to prevent the base 1 from swaying left and right.

[0062] In one implementation, please refer to Figure 2 and Figure 3 The extension direction of the first through hole 111 is consistent with the length direction of the horizontal part 112. The support plate 11 can move relative to the movable rod 5 along the extension direction of the first through hole 111 so that the vertical part 113 is in limiting contact with the side wall of the printer.

[0063] In this embodiment, the first through hole 111 is an elongated hole or a waist-shaped hole, and the extending direction of the first through hole 111 is consistent with the length direction of the horizontal part 112. At this time, the support plate 11 can be horizontally moved and adjusted relative to the movable rod 5 along the extending direction of the first through hole 111.

[0064] When the base 1 is installed in printer notches of different widths, the distance between the vertical part 113 and the printer sidewall can be adjusted by sliding the horizontal support plate 11, so that the vertical part 113 can abut against the printer sidewall and achieve lateral limiting. This allows the position of the support plate 11 in the horizontal direction to be adjusted, so that the base 1 can adapt to different printer sidewall positions.

[0065] In one implementation, please refer to Figure 2 and Figure 3 The movable rod 5 includes a connecting part 51 and a limiting part 52. The connecting part 51 passes through the first through hole 111 and the second through hole 1213 in sequence. The limiting part 52 is sleeved on the end of the connecting part 51 facing away from the support base 121, and the size of the limiting part 52 is larger than the size of the first through hole 111. The limiting part 52 is used to limit the movement of the support plate 11.

[0066] Understandably, the connecting part 51, as the main shaft segment, passes through the first through hole 111 and the second through hole 1213 in sequence to realize the connection and guidance between the support plate 11 and the floating frame 12. The limiting part 52, as the flange structure at the top of the movable rod 5, is sleeved on the end of the connecting part 51 facing away from the support base 121 to form a baffle structure.

[0067] Understandably, when the support plate 11 moves to its limit position along the axis of the movable rod 5, the surface of the support plate 11 contacts the lower end face of the limiting part 52, and the limiting part 52 prevents the support plate 11 from moving outward, thereby limiting the vertical movement range of the support plate 11.

[0068] Optionally, the connecting part 51 and the limiting part 52 can be integrally formed, in which case the movable rod 5 can be a screw or bolt. Alternatively, the connecting part 51 and the limiting part 52 can also be separate parts, in which case the connecting part 51 can be a threaded rod and the limiting part 52 can be a nut.

[0069] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
