Description

Technical Field

[0001] The utility model relates to the field of paper tearing equipment technology, in particular to a paper clamping structure of a lottery machine. Background Art

[0002] The rubber roller used in the automatic cutting mechanism of the lottery machine is usually made of rubber or silicone. This type of rubber roller has good wear resistance and elasticity, which can ensure stable transmission and cutting of paper tickets during the cutting process. There are usually some small grooves or protrusions on the surface of the rubber roller to increase the friction between the paper ticket and ensure that the paper ticket can pass through the cutting mechanism smoothly. In the respective work processes of transmission and cutting, a pair of rubber rollers usually contact and cooperate with each other to transmit the paper.

[0003] However, during the transmission process, in order to match the paper of different thicknesses, the rubber roller can generally be adjusted up and down to a certain extent. However, after the rubber roller is adjustable, the paper entering the movement needs to be clamped more tightly. However, it also causes that when a paper jam occurs, the user needs to return the paper and smooth the paper ticket, and then insert it again. However, due to the squeezing of the paper ticket by a pair of rubber rollers, it is not easy for the user to remove it, and pulling it hard may easily cause the paper to be damaged. Utility Model Content

[0004] In view of this, the present invention aims to overcome the deficiencies of the prior art, and its main purpose is to provide a paper clamping structure for a lottery machine, which not only adapts to different paper sizes, but also facilitates users to perform paper retracting operations when paper jams, thereby overcoming the deficiencies of the prior art.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a paper clamping structure of a lottery machine, including an upper shell and a lower shell that are spliced ​​together and a protective baffle installed on the side of the spliced ​​shell to form a shell, the upper shell and the lower shell are spliced ​​together to form a paper slot that runs through the front and back sides, and a driving component for driving paper to enter the paper slot is also arranged in the shell, a first roller in the upper shell of the driving component and a second roller arranged in the lower shell, including an elastic adjustment component connected to the driving component.

[0006] Furthermore, the inlet end and the outlet end of the upper shell and the lower shell corresponding to the paper slot are respectively inclined toward the inner cavity of the paper slot, and the diameters of the inlet end and the outlet end of the paper slot are enlarged.

[0007] Furthermore, the upper and lower parts of the inlet end and the outlet end of the paper feeding slot are respectively provided with a first baffle corresponding to the inclined surface of the paper feeding slot and a second baffle corresponding to the horizontal surface of the paper feeding slot.

[0008] Furthermore, the contact surface between the first rotating roller and the second rotating roller corresponds to the lower end surface of the paper passing slot.

[0009] Furthermore, one end of the second rotating roller is connected to an extension rod extending outward and penetrating the protective baffle, and the first sliding groove formed on the protective baffle due to the extension rod penetrating therethrough extends longitudinally for the extension rod to move up and down.

[0010] Furthermore, the extended end of the extension rod is connected to a limiting block that fits the surface of the protective baffle, and one end of the limiting block is also connected to the extension block.

[0011] Furthermore, the elastic adjustment component includes a support plate which is arranged in the lower shell body and supports the second rotating roller, and a protrusion extending downward is provided at the lower part of the support plate.

[0012] Furthermore, the elastic adjustment component also includes a support bar arranged on the lower end surface of the protrusion and plugged therein, and a guide groove formed by the support bar plugging into the protrusion.

[0013] Furthermore, the support bar is U-shaped and is sleeved with a base, which is arranged on the lower end surface of the lower shell, and has an insertion opening in the middle for the support bar to insert, and the upper end of the base is also provided with a sleeve-engaging protrusion and a compression spring for the support bar.

[0014] Furthermore, the protective baffle includes two layers, the first sliding groove is located in the inner layer of the protective baffle, the outer layer of the protective baffle is also provided with a second sliding groove corresponding to the first sliding groove, and the extension block extends into the second sliding groove.

[0015] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that through the movable design of the support plate that supports the second roller, when the second roller encounters a paper bill with a large thickness, the support plate will squeeze the compression spring, causing the protrusion to move downward along the support bar. After the paper bill is detached, the second roller is reset under the elastic reset of the compression spring, so that the device can adapt to paper bills of different thicknesses.

[0016] When a paper jam occurs and it is difficult to pull out the paper, an extension block is fixed on the extension rod installed at both ends of the second roller and extends to the outside of the protective baffle and parallel to it, so that the user can move the second roller downward by moving the extension block, making it easier for the user to pull out the jammed paper ticket.

[0017] In order to more clearly illustrate the structural features and functions of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to Figures 1 to 5 As shown, it shows the specific structure of the preferred embodiment of the utility model, which is a paper clamping structure of a lottery machine, which mainly includes a housing 1 composed of an upper housing 11 and a lower housing 12 spliced ​​together, as well as protective baffles 7 installed on both sides of the housing 1, and a base 5 installed at the bottom of the housing 1. In addition, the protective baffle 7 has two layers, an inner layer and an outer layer. The splicing of the upper housing 11 and the lower housing 12 creates a paper slot 2 between the two, both ends of which are connected to the outside world for paper tickets to pass through. In order to facilitate the entry / exit of paper tickets into / from the paper slot 2, the inlet and outlet ends of the upper housing 11 and the lower housing 12 near the paper slot 2 are tilted toward the inside of the paper slot 2, so that the diameter of the inlet and outlet ports of the paper slot 2 is enlarged.

[0029] In addition, to ensure that the direction of the paper ticket entering the paper slot 2 will not deviate, Figure 2 As shown, first baffles 21 are fixed on both sides of the inclined surface of the paper slot 2, and second baffles 22 are fixed on both sides of the horizontal surface of the paper slot 2 adjacent to the inclined surface. The first baffle 21 and the second baffle 22 block the direction of the paper ticket entering the paper slot 2 without deviation.

[0030] In addition, in order to pull the paper ticket into the paper slot 2, as Figure 3 As shown, the upper housing 11 is provided with a first roller 31 whose two ends are connected to the inner layer of the protective baffle 7, and the lower housing 12 is provided with a second roller 32 connected to the inner layer of the protective baffle 7, and the first roller 31 and the second roller 32 are in contact with each other. The paper ticket entering the paper slot 2 will enter between the first roller 31 and the second roller 32 under the friction and pull of the first roller 31 and then move along until it is discharged from the outlet end of the paper slot 2.

[0031] In addition, in order to make the first roller 31 and the second roller 32 suitable for paper bills of different thicknesses, the lower part of the rod body at both ends of the second roller 32 is fitted with a support plate 41, and a downwardly extending protrusion 42 is fixed in the middle of the lower end surface of the support plate 41. Guide grooves 43 are provided on both sides of the protrusion 42, and support bars 44 are inserted into the guide grooves 43. Compression springs 46 are sleeved on the support bars 44 and the protrusion 42, and the upper end of the compression spring 46 contacts the lower end surface of the support plate 41. When paper bills of different thicknesses are inserted between the first roller 31 and the second roller 32, the support plate 41 below the second roller 32 can move downward along the support bar 44 through the guide grooves 43 on the protrusion 42. When there is no paper bill between the first roller 31 and the second roller 32, the support plate 41 drives the second roller 32 to reset under the elastic reset of the compression spring 46.

[0032] In addition, the lower end surface of the base 5 is provided with insertion openings 45 , the support bar 44 is U-shaped and passes through the two insertion openings 45 , and the lower end of the compression spring 46 is fixed to the upper end surface of the base 5 .

[0033] In addition, extension rods 33 are fixed at both ends of the second rotating roller 32. The extension rods 33 can contact the upper end surface of the support plate 41. One end of the extension rod 33 penetrates the inner layer of the protective baffle 7. Figure 5 As shown, the extension rod 33 passes through the protective baffle 7 to form a first sliding groove 36. In order to allow the extension rod 33 to move up and down, the first sliding groove 36 extends downward.

[0034] It should be noted that since the second roller 32 and the support plate 41 are detachable devices, in order to prevent the second roller 32 from separating, a limit block 34 is fixed at one end of the extension rod 33 that passes through the first sliding groove 36. The limit block 34 can be disc-shaped and fits with the inner outer surface of the protective baffle 7, so as to limit the left and right movement of the second roller 32 and prevent it from separating from the support plate 41.

[0035] In addition, in order to avoid paper jam, the first roller 31 and the second roller 32 are pressed too tightly against each other, making it difficult for the user to pull out the paper. Figure 1 As shown, the outer layer of the protective baffle 7 is provided with a second sliding groove 6 corresponding to the first sliding groove 36, and an extension block 35 extending into the second sliding groove 6 is fixed to one end of the limit block 34. When a paper jam occurs, the user can easily separate the paper ticket clamped by the first roller 31 and the second roller 32 by moving the extension block 35 downward.

[0036] In summary, the design focus of the utility model is that through the movable design of the support plate 41 that supports the second roller 32, when the second roller 32 encounters a thick banknote, the support plate 41 will squeeze the compression spring 46, causing the protrusion 42 to move downward along the support bar 44. After the banknote is detached, the second roller 32 is reset under the elastic reset of the compression spring 46, so that the device can adapt to banknotes of different thicknesses.

[0037] When a paper jam occurs and it is difficult to pull out the paper, an extension block 35 is fixed on the extension rod 33 installed at both ends of the second roller 32 and extends to the outside of the protective baffle 7 and parallel to it, so that the user can move the second roller 32 downward by moving the extension block 35, making it convenient for the user to pull out the jammed paper ticket.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
