Detailed implementation manners

[0044] Embodiment 1

[0045] As Figures 1-3As shown, the present embodiment provides a printing device with an automatic dispensing device, including a frame 1, on which are disposed: a storage mechanism 2, the storage mechanism 2 is used to store paper pieces 47 to be printed (the paper pieces 47 may be receipts). A dispensing mechanism 3, the dispensing mechanism 3 includes a first power end 14 and a paper separation assembly 6, the first power end 14 is connected to the paper separation assembly 6 by transmission, the paper separation assembly 6 is connected to the frame 1, the paper separation assembly 6 docks with the storage mechanism 2, so as to rub and separate the paper pieces 47 in the storage mechanism 2, and automatically rub the paper pieces 47 to be printed on the storage mechanism 2 into single paper pieces 47. A conveying mechanism 4, the conveying mechanism 4 includes a second power end 49 and a paper feed assembly 7, the second power end 49 is connected to the paper feed assembly 7 by transmission, the paper feed assembly 7 is connected to the frame 1, and the paper feed assembly 7 docks with the paper separation assembly 6, so as to convey the paper pieces 47 in the paper separation assembly 6 that have been rubbed and separated.

[0046] like Figure 3 and Figure 4 As shown, in this embodiment, the storage mechanism 2 includes a supporting platform 8, a limiting member assembly 10, and a supporting member 9. The limiting member assembly 10 and the supporting member 9 are arranged on the supporting platform 8. The supporting platform 8 is used to support the paper piece 47, and the limiting member assembly 10 is used to limit the position of the paper piece 47 on the supporting platform 8.

[0047] A hinge shaft 11 is respectively provided at both ends of the supporting platform 8, and the supporting platform 8 is rotatably connected with the frame 1 through the hinge shaft 11. A first elastic member 22 (the first elastic member 22 can be a spring) is provided at the bottom of the supporting platform 8, and one end of the first elastic member 22 is connected to the bottom of the supporting platform 8 in abutment with each other, and the other end is connected to the frame 1 in abutment with each other, so as to realize the docking of the supporting platform 8 and the paper separation assembly 6 through the first elastic member 22.

[0048] Specifically, the first elastic member 22 is arranged below the carrier 8 so that the carrier 8 can always maintain an upward elastic force. The support member 9 is arranged on the left and right sides of the front end of the carrier 8. The hinge shaft 11 is arranged on both sides of the rear end of the carrier 8, and the carrier 8 can rotate at a small angle around the hinge shaft 11. The limiter assembly 10 includes three limiters, which are respectively arranged at three direction positions on the plane of the carrier 8 to limit the storage position of the paper piece 47, two of which are arranged at opposite positions, and the other limiter is arranged at a position between the two hinge shafts 11 at the rear end.

[0049] like Figure 5 and Figure 6 As shown, in this embodiment, the paper separation assembly 6 includes a first rotating shaft 12, a paper separation wheel 16, and a stop assembly 13. The paper separation wheel 16 is disposed on the first rotating shaft 12, and the first power end 14 is drivingly connected to the first rotating shaft 12, so that the paper separation wheel 16 can contact the paper piece 47 on the storage mechanism 2. One end of the stop assembly 13 is connected to the frame 1, and the other end of the stop assembly 13 is abutted against and connected to the paper separation wheel 16, so that the paper separation wheel 16 rubs and separates a single paper piece 47.

[0050] In this embodiment, the sheet separating assembly 6 further includes a first gear 18. The first gear 18 is arranged on the first rotating shaft 12 and is connected to the first power end 14 through the first conveyor belt 15.

[0051] The sheet separating wheel 16 includes an umbrella-shaped structure, and the outer surface of the sheet separating wheel 16 is covered with an elastic material. The setting of the elastic material can enhance the friction on the surface of the sheet separating wheel 16 and at the same time can avoid the phenomenon that the sheet separating wheel 16 damages the surface of the paper member 47.

[0052] Specifically, the elastic material includes rubber, resin, fiber, etc.

[0053] Specifically, both ends of the first rotating shaft 12 are limited and fixed to the left and right side plates of the frame 1 through bushings. The sheet separating wheel 16 is arranged at the middle position of the first rotating shaft 12. The sheet separating wheel 16 has an umbrella-shaped structure, and the outer surface is covered with a layer of sand pattern rubber and can rotate circumferentially with the first rotating shaft 12 to rub and separate the paper member 47. A plurality of edge blocking rollers 52 are also arranged on the first rotating shaft 12. The edge blocking rollers 52 are respectively arranged on both sides of the sheet separating wheel 16 and can freely rotate around the first rotating shaft 12. The first gear 18 is arranged at one end of the first rotating shaft 12. The first gear 18 is connected to the first power end 14 through the first conveyor belt 15, and the first power end 14 drives the first rotating shaft 12 to rotate through the first conveyor belt 15.

[0054] As Figure 7 shown, specifically, the stop assembly 13 includes a platen 37, a guide plate 38, a backing plate 39, a platen spring 40, and a platen bracket 41. The material of the backing plate 39 is a wear-resistant rubber pad, which is arranged in the groove on the upper plane of the platen 37. The guide plate 38 is made of thin sheet stainless steel and is coated on the platen 37. The platen 37 is arranged on the platen bracket 41. Through the limiting member on the platen bracket 41, the platen 37 can slide relative to the platen bracket 41 in the up and down direction, and the platen spring 40 is placed between the platen 37 and the platen bracket 41 to keep the platen 37 under an upward thrust, so that the platen 37 contacts the sheet separating wheel 16. The platen bracket 41 is fixedly arranged on the frame 1.

[0055] As Figure 3 shown, in this embodiment, the sheet separating assembly 6 further includes a cam 17. The cam 17 is arranged on the first rotating shaft 12, and the bearing table 8 is provided with a support member 9 that cooperates with the cam 17, so that the paper member 47 on the bearing table 8 can be periodically rubbed and separated by the sheet separating wheel 16.

[0056] Specifically, as Figures 3-7As shown, paper pieces 47 are stacked on the carrier 8, and the two sides of the rear end of the carrier 8 are connected to the frame 1 through the hinge shaft 11. Cams 17 are arranged on both sides of the first rotating shaft 12, and support members 9 are arranged on both sides of the front end of the carrier 8 and can contact the cams 17. When the first power end 14 drives the first rotating shaft 12 to rotate through the first conveyor belt 15, when the cam 17 rotates to the position of the concave point direction of the cam 17 as the first rotating shaft 12 rotates, the first elastic member 22 under the carrier 8 pushes the carrier 8, so that the carrier 8 rotates upward around the hinge shaft 11 and is lifted, so that the paper pieces 47 on the carrier 8 contact the paper separation wheel 16, and the paper separation wheel 16 rotates with the first rotating shaft 12.

[0057] The paper separation wheel 16 rubs the paper piece 47 onto the stop assembly 13, and the table spring 40 gives an upward thrust to the table 37, so that the pad 39 is tightly fitted with the paper separation wheel 16. The paper separation wheel 16 continues to rotate, and the friction force causes the paper piece 47 to pass between the paper separation wheel 16 and the pad 39. When the paper piece 47 passes through the pad 39, it is affected by the friction force to ensure that only the top paper piece 47 passes. The paper separation wheel 16 continues to rotate and transports the paper piece 47 to the paper feeding assembly 7. As the first rotating shaft 12 continues to rotate, when the cam 17 rotates to the convex point position, the supporting platform 8 rotates and descends around the hinge shaft 11, so that the paper piece 47 is away from the paper separation wheel 16. At this point, the first rotating shaft 12 stops rotating, and the rubbing of a paper piece 47 is completed.

[0058] like Figures 8-10 As shown, in this embodiment, the paper feeding assembly 7 includes a second rotating shaft 19, a first roller 20, a second roller 42, a connecting member 44, and a second bracket 43. The first roller 20 is inserted into the second rotating shaft 19, and the second power end 49 is transmission-connected to the second rotating shaft 19.

[0059] One end of the connecting member 44 is connected to the frame 1 , the second bracket 43 is slidably disposed on the connecting member 44 , and the second roller 42 is passed through one end of the second bracket 43 .

[0060] The second roller 42 and the first roller 20 are pressed against each other, so that the single paper piece 47 that has been separated in the paper separation assembly 6 passes between the first roller 20 and the second roller 42 to achieve transmission. The second roller 42 and the first roller 20 are arranged opposite to each other.

[0061] like Figure 1 and Figure 8 As shown, the paper feeding assembly 7 further includes a second gear 21 , which is disposed at one end of the second rotating shaft 19 and connected to the second power end 49 via a second conveyor belt 50 .

[0062] Specifically, Figure 8As shown, the connecting member 44 is connected to the frame 1 through the first plate member 56. One end of the first plate member 56 is connected to the frame 1, and the other end of the first plate member 56 is connected to the connecting member 44. At another position of the frame 1, a second plate member 57 that cooperates with the first plate member 56 is provided. The first plate member 56 and the second plate member 57 are arranged oppositely, and there is a gap between the first plate member 56 and the second plate member 57. The paper member 47 can pass through this gap. The arrangement of the first plate member 56 and the second plate member 57 can guide the paper member 47 and play a guiding role. The other end of the first plate member 56 and the second plate member 57 respectively include through holes, and the second roller 42 and the first roller 20 are respectively inserted into two through holes on the other end of the first plate member 56 and the second plate member 57, so that the paper member 47 can pass between the first roller 20 and the second roller 42 and be completely conveyed out from the gap between the first plate member 56 and the second plate member 57.

[0063] As Figure 10 shown, in this embodiment, the paper feeding assembly 7 further includes a second elastic member 45 (the second elastic member 45 can be a spring). One end of the second elastic member 45 is connected to the second bracket 43, and the other end of the second elastic member 45 is connected to the second roller 42.

[0064] Specifically, as Figure 8 and Figure 10 shown, the second roller 42 is arranged on the second bracket 43. The second roller 42 can freely rotate in a circular motion around its axis. The second bracket 43 is arranged on the connecting member 44, and the connecting member 44 is connected to the frame 1. The second bracket 43 can linearly slide up and down within a limited range relative to the connecting member 44. The second elastic member 45 is arranged between the second bracket 43 and the connecting member 44, so that the second bracket 43 always maintains a downward thrust, and the second roller 42 and the first roller 20 are in mutual contact and extrusion, forming two sets of conveying rollers.

[0065] In this embodiment, the outer surfaces of the first roller 20 and the second roller 42 are respectively covered with an elastic material.

[0066] Specifically, the elastic material includes rubber, resin, fiber, etc.

[0067] As Figure 1 shown, a printing device with an automatic dispensing device includes a printing device body 55. The printing device body 55 is arranged on the frame 1 and is connected to the paper feeding assembly 7.

[0068] Specifically, the paper member 47 on the bearing table 8 is conveyed from the paper separating assembly 6 to the paper feeding assembly 7. The second power end 49 drives the second rotating shaft 19 to rotate through the second conveyor belt 50. The paper member 47 continues to move forward between the first roller 20 and the second roller 42 and enters the printing device body 55 for printing.

[0069] Compared with the prior art, a printing device with an automatic dispensing device provided according to the present invention includes a frame, a storage mechanism, a dispensing mechanism, a conveying mechanism, and a printing device body. The storage mechanism, the dispensing mechanism, the conveying mechanism, and the printing device body are arranged on the frame, and the storage mechanism is used to store paper pieces to be printed. The dispensing mechanism includes a first power end and a paper separation assembly. The first power end is connected to the paper separation assembly by transmission. The paper separation assembly docks with the storage mechanism to rub and separate the paper pieces in the storage mechanism. The conveying mechanism includes a second power end and a paper feeding assembly. The second power end is connected to the paper feeding assembly by transmission. The paper feeding assembly docks with the paper feeding assembly. The paper feeding assembly conveys the rubbed and separated paper pieces in the paper separation assembly to the printing device body for printing.

[0070] Thus, through the cooperation between the paper separation component and the paper feeding component, the paper pieces to be printed in the storage mechanism can be automatically separated into single sheets by the paper separation component, and the separated single sheets of paper can be automatically transmitted to the printing device body by the paper feeding component for printing. The printing efficiency of the printing device with an automatic dispensing device is improved, the user's operation time is saved, the labor cost is reduced, and the errors that are easy to occur when manually dispensing paper pieces are avoided, making the printing process simple and fast, while enhancing the user's work efficiency and further improving the user's experience.

[0071] Specifically, a limit member assembly is provided on the support platform, and the limit member assembly positions the paper piece to be printed on the support platform, so that the paper piece to be printed can be stably placed on the support platform, further ensuring the normal operation of the subsequent paper separation assembly operation.

[0072] Specifically, a first elastic member is provided at the bottom of the supporting platform. Through the cooperation of the cam on the first rotating shaft and the supporting member on the supporting platform, the paper pieces to be printed on the supporting platform can be periodically separated by the paper separation wheel through the push of the first elastic member, thereby realizing automatic separation of single sheets.

[0073] Specifically, the outer surface of the paper separation wheel is covered with elastic material. The setting of the elastic material can enhance the friction of the outer surface of the paper separation wheel, so that the paper pieces to be printed on the supporting platform can smoothly pass between the paper separation wheel and the stop assembly to achieve automatic single-sheet separation.
