Description

Technical Field

[0001] This utility model relates to the field of card delivery technology, and in particular to a card delivery mechanism and a card storage device. Background Technology

[0002] During card storage and processing, the cards are first transported from inside the card box to the card conveying device via a transmission mechanism. The card conveying device then transports the cards to the printer for storage and processing. However, during the process of transporting the cards from the card conveying device to the printer, the cards still need to travel a certain distance. During this process, only the conveyor wheels of the card conveying device roll against the bottom of the card, which can easily cause the card to deviate from its path, resulting in the card not being accurately delivered to the printer. Utility Model Content

[0003] The main purpose of this invention is to propose a card feeding mechanism that aims to solve the problem that cards are prone to path deviation during the process of transporting them from the card feeding device to the printer, resulting in the cards not being accurately delivered into the printer.

[0004] To solve the above problems, this utility model proposes a card delivery mechanism, comprising:

[0005] The housing has an internal mounting cavity. Oppositely arranged card inlet and card outlet openings are located at both ends of the housing along the card transport direction. Both the card inlet and card outlet are connected to the mounting cavity. The card inlet is used to connect to a card transport device, and the card outlet is used to connect to a printer. A clearance opening is provided at the bottom of the housing.

[0006] The pressure roller assembly is rotatably connected to the mounting cavity and partially extends out of the clearance opening. It is arranged opposite to the conveyor wheel of the card transport device so that they can roll together and abut against the two surfaces of the card.

[0007] In one embodiment, the pressure roller assembly can move relative to the housing in a direction perpendicular to the card transport to adjust the distance between itself and the transfer roller.

[0008] In one embodiment, the pressure roller assembly includes a mounting rod and a roller, the roller being rotatably connected to the mounting rod;

[0009] The housing contains a protective shell, and the protective shell has a groove at each end in the direction perpendicular to the card transport direction. The two ends of the mounting rod can slide in the two grooves to adjust the distance between the roller and the conveying wheel.

[0010] In one embodiment, the pressure roller assembly further includes two elastic buffers, one end of which is connected to one end of the mounting rod, and the other extended end is connected to one end of the protective shell perpendicular to the card transport direction.

[0011] In one embodiment, the pressure roller assembly further includes two limiting members, which are installed at both ends of the mounting rod and abut against the grooved edges of the two slides.

[0012] In one embodiment, the card feeding mechanism further includes two first card connectors, which are disposed at both ends of the housing perpendicular to the card transport direction and are used to engage with the printer.

[0013] In one embodiment, the card feeding mechanism further includes a second latching member, which is disposed at one end of the housing and is used to latch with the card transport device.

[0014] In one embodiment, the card feeding mechanism further includes a locking element, which is disposed at one end of the housing and spaced apart from the second card receiving element. The locking element is used to lock the card feeding mechanism and the card transport device.

[0015] In one embodiment, the card feeding mechanism further includes a handle mounted on the end of the housing away from the clearance opening.

[0016] This utility model also proposes a card storage device, including a card transport device, a card delivery mechanism, and a printer. The card delivery mechanism is the card delivery mechanism described above. The card transport device is connected to the end of the card delivery mechanism away from the card transport direction, and the printer is connected to the end of the card delivery mechanism facing the card transport direction.

[0017] This invention proposes a card feeding mechanism, including a housing and a pressure roller assembly. This mechanism is installed between a card conveying device and a printer. When a card is transported outside the card conveying device, it enters the housing through the card inlet and is then transported to the printer through the card outlet. During this process, the pressure roller assembly and the conveying rollers roll against both ends of the card, fixing the two surfaces of the card and ensuring that the card's transport path does not deviate. This guarantees that the card can be accurately transported into the printer, improving card transport efficiency. Attached Figure Description

[0031] During card storage and processing, the cards are first transported from inside the card box to the card conveying device via a transmission mechanism. The card conveying device then transports the cards to the printer for storage and processing. However, during the process of transporting the cards from the card conveying device to the printer, the cards still need to travel a certain distance. During this process, only the conveyor wheels of the card conveying device roll against the bottom of the card, which can easily cause the card to deviate from its path, resulting in the card not being accurately delivered to the printer.

[0032] To address the aforementioned problems, this utility model proposes a card feeding mechanism, which aims to solve the problem that cards are prone to path deviation during the process of transporting them from the card feeding device to the printer, resulting in the cards not being accurately delivered into the printer.

[0033] like Figures 1 to 3 In one embodiment, the card feeding mechanism 100 includes a housing 10 and a pressure roller assembly 20. The housing 10 has an installation cavity inside. The housing 10 has a card inlet 11 and a card outlet 12 at both ends along the card transport direction. The card inlet 11 and the card outlet 12 are both connected to the installation cavity. The card inlet 11 is used to connect with the card transport device 200, and the card outlet 12 is used to connect with the printer 300. The bottom end of the housing 10 has a clearance opening. The pressure roller assembly 20 is rotatably connected to the installation cavity and partially extends out of the clearance opening. It is used to be opposite to the conveyor wheel of the card transport device 200 so that they can roll together to abut against both ends of the card.

[0034] In this embodiment, the housing 10 serves as the main frame of the card feeding mechanism 100, specifically a box-like structure with a hollow interior forming an installation cavity. This cavity accommodates other components of the card feeding mechanism 100, such as the pressure roller assembly 20, and provides space for their installation and operation. The housing 10 is made of a high-strength and wear-resistant material, such as plastic or metal, to ensure sufficient structural stability. A card inlet 11 and a card outlet 12, both at the same height, are located at the bottom of the housing 10. The card inlet 11 is connected to the card conveying device 200, allowing cards conveyed by the device to enter the card feeding mechanism 100. The card outlet 12 is connected to the printer 300; after the card is conveyed within the card feeding mechanism 100, it enters the printer 300 through the outlet 12 for printing. A clearance opening is located at the bottom of the housing 10, providing space for the pressure roller assembly 20 or the conveying rollers of the card conveying device 200, enabling them to work together. The pressure roller assembly 20 is rotatably connected to the mounting cavity and partially extends out of the clearance opening, positioned opposite to the conveyor wheel of the card conveying device 200. In other embodiments, the conveyor wheel may also partially extend into the clearance opening, positioned opposite to the pressure roller assembly 20. During card transport, the card is sandwiched between the pressure roller assembly 20 and the conveyor wheel. When the conveyor wheel rotates, the pressure roller assembly 20 rotates accordingly, and both roll together against the ends of the card. Friction forces drive the card smoothly from the card inlet 11 to the card outlet 12, achieving continuous card transport.

[0035] The card feeding mechanism 100 proposed in this utility model includes a housing 10 and a pressure roller assembly 20. This mechanism 100 is installed between the card conveying device 200 and the printer 300. When a card is transported to the outside of the card conveying device 200, it enters the housing 10 through the card inlet 11 and is then transported to the inside of the printer 300 through the card outlet 12. During this process, the pressure roller assembly 20 and the conveying roller roll against both ends of the card, forming a stable clamping force on both ends. Compared to a single conveying method, this rolling and abutting conveying method effectively avoids card offset, skewing, or even jamming during transmission, ensuring that the card's transport path remains unchanged and thus guaranteeing accurate delivery of the card to the printer 300, improving card transport efficiency.

[0036] like Figures 1 to 3 In one embodiment, the pressure roller assembly 20 can move relative to the housing 10 in a direction perpendicular to the card transport to adjust the distance between itself and the transfer roller.

[0037] In this embodiment, the pressure roller assembly 20 can move relative to the housing 10 in a direction perpendicular to the card transport. Specifically, grooves 31 can be formed on both sides of the housing 10, and the pressure roller assembly 20 can move within the grooves 31; or a slide rail and slider structure can be provided inside the housing 10, with the pressure roller assembly 20 mounted on the slider, which can slide on the slide rail in a direction perpendicular to the card transport. This connection method allows adjustment of the distance between the pressure roller assembly 20 and the conveyor wheel to accommodate cards of different thicknesses. By adjusting the distance, when transporting thinner cards, the distance can be reduced so that the pressure roller assembly 20 and the conveyor wheel can tightly clamp the card, ensuring transport stability; when transporting thicker cards, the distance can be increased to avoid damage to the card due to insufficient distance, and also to prevent excessive transport resistance due to excessively thick cards, which could affect transport efficiency or even cause equipment jamming. This improves the adaptability of the card feeding mechanism 100 to different types of cards and enhances the versatility of the card feeding mechanism 100.

[0038] like Figures 1 to 3 In one embodiment, the pressure roller assembly 20 includes a mounting rod 21 and a roller 22, with the roller 22 rotatably connected to the mounting rod 21;

[0039] The housing 10 is provided with a protective shell 30. The protective shell 30 has a sliding groove 31 at each end in the direction perpendicular to the card transport direction. The two ends of the mounting rod 21 can slide in the two sliding grooves 31 to adjust the distance between the roller 22 and the conveyor wheel.

[0040] In this embodiment, the pressure roller assembly 20 further includes a mounting rod 21 and a roller 22. The mounting rod 21 is a supporting component of the pressure roller assembly 20 and is usually made of a high-strength metal material, such as stainless steel. The roller 22 is the component that directly contacts the card and realizes card transfer. Its surface is often made of wear-resistant and elastic rubber material, which can ensure sufficient friction between the roller and the card to move the card while avoiding damage to the card surface. The roller 22 is mounted on the mounting rod 21 through rotating connecting components such as bearings, so that the roller 22 can rotate freely and reduce resistance during card transfer. The protective shell 30 is disposed inside the housing 10. The connection between the protective shell 30 and the housing 10 can be a snap-fit ​​or a threaded connection to ensure the installation stability between the two. The protective shell 30 covers the outside of the pressure roller assembly 20 to prevent dust and debris from entering and affecting the smoothness of adjustment. Specifically, the protective shell 30 has grooves 31 at both ends in the vertical card transport direction. The grooves 31 extend in the vertical direction. The design of the grooves 31 provides guidance and constraint for the movement of the mounting rod 21. By moving the two ends of the mounting rod 21 in the grooves 31, the distance between it and the conveyor wheel can be adjusted to adapt to the transmission needs of cards of different thicknesses.

[0041] like Figures 1 to 3In one embodiment, the pressure roller assembly 20 further includes two elastic buffers 23, one extension of which is connected to one end of the mounting rod 21, and the other extension is connected to one end of the protective shell 30 perpendicular to the card transport direction.

[0042] In this embodiment, the elastic buffer 23 can be a spring, torsion spring, or other elastic component. One end is fixedly inserted into the protective shell 30, and the other end is a semi-annular structure. A mounting groove is provided at the corresponding position of the mounting rod 21 so that the other end of the semi-annular structure is fitted into the mounting groove to ensure the stability of the connection. At the same time, the two elastic buffers 23 are symmetrically designed. When the card thickness changes, the mounting rod 21 drives the roller 22 to move in the slide groove 31 to adjust the distance between it and the conveying wheel. The elastic buffer 23 will undergo compression or stretching deformation accordingly. For example, when conveying a thicker card, the card pushes the roller 22 to move upward, the mounting rod 21 rises in the slide groove 31, the elastic buffer 23 is compressed, and its own elastic force gives the mounting rod 21 a downward reaction force, so that the roller 22 can fit tightly against the card without damaging the card due to excessive pressure. When conveying a thinner card, the elastic buffer 23 is in a stretched or relatively relaxed state, which can also provide appropriate pressure to the roller 22 to ensure stable clamping and conveying of the card. The elastic buffer 23 enables adaptive adjustment to changes in card thickness and also acts as a buffer and shock absorber during card transport, further improving the stability and efficiency of card delivery.

[0043] like Figures 1 to 3 In one embodiment, the pressure roller assembly 20 further includes two limiting members 24, which are installed at both ends of the mounting rod 21 and abut against the grooved edges of the two sliding grooves 31.

[0044] In this embodiment, the main structure of the limiting member 24 is a hollow cylinder, and a ring is welded or integrally formed at one end away from the interior of the mounting cavity. When the limiting member 24 is fitted onto one end of the mounting rod 21, the ring will abut against the edge of the opening of the slide groove 31 to prevent the mounting rod 21 from moving axially. This ensures that the mounting rod 21 can only be adjusted according to the card thickness in the vertical card transport direction, so that the roller 22 always maintains the correct relative position with the conveyor wheel, stably clamping and transporting the card, and further improving the transport stability of the card feeding mechanism 100.

[0045] like Figures 1 to 6 In one embodiment, the card feeding mechanism 100 further includes two first card connectors 40, which are located at both ends of the housing 10 perpendicular to the card transport direction and are used to connect to the printer 300.

[0046] In this embodiment, two first card connectors 40 are threaded to both ends of the housing 10 perpendicular to the card conveying direction to ensure their installation stability. At the same time, the end of the first card connector 40 near the printer 300 has a hook-shaped structure. The printer 300 has two corresponding slots. When the hook-shaped structure of the first card connector 40 extends from the slot into the printer 300, it will engage with the slot wall, thereby connecting the card feeding mechanism 100 and the printer 300. This connection method is simple to operate and facilitates the installation or disassembly of the card feeding mechanism 100, significantly speeding up the installation of the equipment and reducing labor costs.

[0047] In other embodiments, the card feeding mechanism 100 further includes two third card connectors 60, which are also threadedly connected to both ends of the housing 10 perpendicular to the card transport direction and are spaced apart from the first card connectors 40. Specifically, the two first card connectors 40 are installed at the upper part of both ends of the housing 10, and the two third card connectors 60 are installed at the lower part of both ends of the housing 10. The structure and installation method of the third card connectors 60 are the same as those of the first card connectors 40. The arrangement of the third card connectors 60, together with the first card connectors 40, realizes the fixation of the card feeding mechanism 100 and the printer 300 at different heights, further improving the installation stability of the two.

[0048] like Figures 1 to 6 In one embodiment, the card feeding mechanism 100 further includes a second card connector 50, which is disposed at one end of the housing 10 and is used to engage with the card delivery device 200.

[0049] In this embodiment, a second latching member 50 is provided at one end of the housing 10 near the card-carrying device 200. The connection between the second latching member 50 and the housing 10 can be welding or integral design to ensure the stability of the connection between the two. Both ends of the second latching member 50 are also hook-shaped structures, and the two hook-shaped structures are connected by a metal plate. One end of the card-carrying device 200 has two corresponding slots. By latching the two hook-shaped structures into the slots, the connection between the card-carrying device 200 and the card-feeding mechanism 100 is realized, and disassembly is convenient, further improving the installation flexibility of the card-feeding mechanism 100.

[0050] like Figures 1 to 6 In one embodiment, the card feeding mechanism 100 further includes a locking member 70, which is disposed at one end of the housing 10 and spaced apart from the second card receiving member 50. The locking member 70 is used to lock the card feeding mechanism 100 and the card transport device 200.

[0051] In this embodiment, the locking member 70 includes an external mounting shell with an L-shaped design. A button is mounted at its vertical end, and a movable locking hook is provided at its horizontal end. A connecting rod is provided inside the mounting shell to connect the button and the locking hook. When the button is pressed, the locking hook retracts into the mounting shell; when the button is released, the locking hook extends out of the mounting shell. When the card feeding mechanism 100 is installed onto the card transport device 200, the button is first pressed to retract the locking hook into the mounting shell, and then the second engaging member 50 initially engages with the card transport device 200. Afterward, the button is released, allowing the locking hook to extend and engage with the card transport device 200, thus further locking the card feeding mechanism 100 and the card transport device 200 to prevent relative displacement during operation. The locking fastener 70, in cooperation with the second locking fastener 50, forms a dual protection mechanism of "first locking and positioning, then locking and reinforcement", which further improves the connection reliability between the card delivery mechanism 100 and the card transport device 200.

[0052] like Figure 1 In one embodiment, the card feeding mechanism 100 further includes a handle 80, which is mounted on the end of the housing 10 away from the clearance opening.

[0053] In this embodiment, the handle 80 can be installed on the housing 10 by means of threaded connection, snap-fit, or embedded installation. When the card feeding mechanism 100 needs to be installed in different positions, or when the equipment needs to be maintained or debugged, the operator can hold the handle 80 to move the card feeding mechanism 100. In addition, when operating the card feeding mechanism 100, the handle 80 can also serve as a leverage point, making it convenient for the operator to position and adjust the angle of the card feeding mechanism 100, so that the card feeding mechanism 100 can be more accurately connected with the card conveying device 200, printer 300, and other equipment, further improving the practicality of the card feeding mechanism 100.

[0054] like Figures 1 to 6 This utility model also proposes a card storage device, including a card transport device 200, a card delivery mechanism 100, and a printer 300. The card transport device 200 is connected to the end of the card delivery mechanism 100 away from the card transport direction, and the printer 300 is connected to the end of the card delivery mechanism 100 facing the card transport direction. The specific structure of the card delivery mechanism 100 is as described in the above embodiments. Since the card delivery mechanism 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0055] 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 using the contents of the present utility model specification and drawings under the technical concept of the present utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
