The spacing between the upper and lower blocks is preset. However, in actual use, if the spacing between the upper and lower blocks cannot be adjusted for playing cards of varying thicknesses, a single card or two playing cards may pass through the entry opening simultaneously, causing inconvenience to the user. Utility Model Content

[0003] The purpose of the utility model is to provide a card dealing machine, which can effectively solve the problem that the card adjusting mechanism of the existing card dealing machine cannot adjust the spacing according to the thickness of the playing cards.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] A card dealing machine includes a shell, wherein a card bin for storing playing cards, a card outlet channel, and a card feeding mechanism for pushing playing cards into the card outlet channel are provided in the shell, the card outlet channel having a card entry port connected to the card bin, the card dealing machine also including a card adjusting mechanism arranged at the card entry port for limiting the number of playing cards pushed into the card outlet channel, the card adjusting mechanism including a lower card rubbing block located below the card entry port and an upper card rubbing block located above the card entry port and cooperating with the lower card rubbing block, the upper card rubbing block being arranged above the lower card rubbing block by a height adjusting member, and the height adjusting member adjusting the distance between the upper card rubbing block and the lower card rubbing block.

[0006] In the above-mentioned card dealing machine, the upper shuffling block is rotatably connected in the shell, and the upper shuffling block has at least two shuffling positions. The distances from the points of the upper shuffling block closest to the lower shuffling block on adjacent shuffling positions to the rotation axis of the upper shuffling block are different, and the height adjustment member drives the upper shuffling block to rotate, so as to switch the shuffling block to cooperate with the lower shuffling block at different shuffling positions.

[0007] In the above-mentioned card dealing machine, the height adjustment member includes an adjustment shaft rotatably arranged on the shell, and the upper card rubbing block is an eccentric wheel. The adjustment shaft drives the eccentric wheel to rotate to switch different card rubbing positions to cooperate with the lower card rubbing block.

[0008] In the above-mentioned card dealing machine, a rotating hole is formed on the housing, and the adjusting shaft is tightly fitted with the rotating hole.

[0009] In the above-mentioned card dealing machine, a silicone pad is provided between the adjusting shaft and the rotating hole.

[0010] In the above-mentioned card dealing machine, the silicone pad is coated on the adjusting shaft; or the silicone pad is fixed on the inner side wall of the rotating hole.

[0011] In the above-mentioned card dealing machine, an adjustment hole is provided on the housing corresponding to the end of the adjustment shaft.

[0012] In the above-mentioned card dealing machine, the upper card rubbing block is slidably arranged in the housing, and the height adjusting member drives the upper card rubbing block to slide, thereby adjusting the distance between the upper card rubbing block and the lower card rubbing block.

[0013] In the above-mentioned card dealing machine, the height adjusting member includes an adjusting bolt threadedly connected to the housing, and an end portion of the adjusting bolt is rotatably connected to the upper card shuffling block.

[0014] In the above-mentioned card dealing machine, the lower card rubbing block is movably arranged on the housing, and an elastic mechanism for lifting the lower card rubbing block is provided between the bottom of the lower card rubbing block and the housing.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] By adding a height adjustment member to adjust the spacing between the upper and lower card shuffling blocks, the problem of the current card-handling mechanism being unable to adjust the spacing according to the thickness of the playing cards is solved. The upper card shuffling block is located above the lower card shuffling block, and the spacing between the upper and lower card shuffling blocks is limited to only one playing card passing through at a time. The upper card shuffling block is set above the lower card shuffling block via a height adjustment member, and the height adjustment member can be used to adjust the spacing between the upper and lower card shuffling blocks. Thus, the spacing between the upper and lower card shuffling blocks can be adjusted according to the thickness of different playing cards, ensuring that playing cards of different thicknesses can only pass through one at a time, thereby increasing the ability of the card dealing machine to adapt to playing cards of different thicknesses.

[0017] Furthermore, the upper rubbing block is rotatably connected within the housing, the upper rubbing block having at least two rubbing positions, the points of the upper rubbing block closest to the lower rubbing block at adjacent rubbing positions being at different distances from the rotation axis of the upper rubbing block, and the height adjustment member driving the upper rubbing block to rotate so as to switch the rubbing block to cooperate with the lower rubbing block at different rubbing positions. The height adjustment member driving the upper rubbing block to rotate, switching the upper rubbing block to different rubbing positions, achieving different spacings between the upper rubbing block and the lower rubbing block, and being able to adjust the rubbing speed according to the thickness of common playing cards.

[0018] Furthermore, the height adjustment member includes an adjustment shaft rotatably mounted on the housing, and the upper shuffling block is an eccentric wheel. The adjustment shaft drives the eccentric wheel to rotate to switch between different shuffling positions and cooperate with the lower shuffling block. By driving the eccentric wheel with the adjustment shaft, stepless adjustment can be achieved within a certain range, more accurately adapting to playing cards of different thicknesses.

[0019] Furthermore, a rotating hole is formed on the housing, and the adjusting shaft is tightly matched with the rotating hole. The tightly matched adjusting shaft and rotating hole enable the adjusting shaft to maintain a certain position after being rotated to the certain position, thereby fixing the upper card rubbing block to stay at the card rubbing position.

[0020] Furthermore, a silicone pad is provided between the adjustment shaft and the rotary hole to increase the friction between the adjustment shaft and the inner wall of the rotary hole. When playing cards pass through the upper shuffling block, sufficient friction between the adjustment shaft and the rotary hole ensures that the upper shuffling block is not rotated by the friction of the playing cards.

[0021] Furthermore, the silicone pad is coated on the adjustment shaft; or the silicone pad is fixed to the inner wall of the rotating hole. The two different arrangements of the silicone pad can both serve the purpose of fixing the relative position of the silicone pad, the adjustment shaft and the rotating hole.

[0022] Furthermore, an adjustment hole is provided on the housing corresponding to the end of the adjustment shaft. Through the adjustment hole, the adjustment shaft can be rotated by a tool to adjust the rubbing position of the upper rubbing block.

[0023] Furthermore, the upper rubbing block is slidably arranged in the housing, and the height adjustment member drives the upper rubbing block to slide, thereby adjusting the distance between the upper rubbing block and the lower rubbing block. In another arrangement of the upper rubbing block, the height adjustment member drives the upper rubbing block to slide, thereby adjusting the distance between the upper rubbing block and the lower rubbing block.

[0024] Furthermore, the height adjustment member includes an adjustment bolt threadedly connected to the housing, the end of which is rotatably connected to the upper shuffling block. The adjustment bolt not only allows for precise adjustment of the height of the upper shuffling block, but also provides a self-locking feature in the threaded connection, ensuring that the height of the upper shuffling block does not change due to compression with the playing cards after adjustment.

[0025] Furthermore, the lower card rubbing block is movably mounted on the housing, and an elastic mechanism is provided between the bottom of the lower card rubbing block and the housing to lift the lower card rubbing block. The movability of the lower card rubbing block on the housing allows the lower card rubbing block to dynamically adjust the distance between the lower card rubbing block and the upper card rubbing block, thus providing the entire card adjustment mechanism with a wider adjustment range.

[0040] Example 1

[0041] See Figures 1 to 5 This is a first embodiment of a card dealing machine of the present invention, which includes a shell 100, in which a card bin 110 for storing playing cards is formed, a card outlet passage 120 is provided on the front side of the shell 100 corresponding to the bottom of the card bin 110, and the card outlet passage 120 has a card inlet 121 connected to the card bin 110, a card feeding mechanism 200 for pushing playing cards into the card outlet passage 120 is provided in the card bin 110, a card adjusting mechanism 300 for limiting the number of playing cards entering the card outlet passage 120 is provided at the card inlet 121, and a card ejecting mechanism is provided in the card outlet passage 120 downstream of the card adjusting mechanism 300. Its working principle is that the playing cards are stacked and placed in the card bin 110, and the card feeding mechanism 200 pushes the playing cards on the bottom layer from the card entry port 121 into the card exit passage 120. The card adjusting mechanism 300 located at the card entry port 121 controls that only one playing card enters the card exit passage 120 at a time, and the playing cards entering the card exit passage 120 will be ejected out of the card exit passage 120 by the card ejecting mechanism.

[0042] The card adjustment mechanism 300 comprises an upper card rubbing block 320 and a lower card rubbing block 310, and the upper card rubbing block 320 is positioned at directly above the lower card rubbing block 310, and the spacing between the upper card rubbing block 320 and the lower card rubbing block 310 is controlled to be greater than a playing card thickness and less than two playing card thicknesses, thereby realizing that only one playing card can pass through at each time.But because the thickness of different playing cards is different, it is necessary to regulate the spacing between the upper card rubbing block 320 and the lower card rubbing block 310.Therefore, in housing 100, increase height adjustment member 400, the upper card rubbing block 320 is arranged on the top of the lower card rubbing block 310 by height adjustment member 400, and the spacing between the upper card rubbing block and the lower card rubbing block can be adjusted by height adjustment member 400, thereby is the playing cards of adaptive different thicknesses.

[0043] In the present embodiment, upper rubbing card block 320 is rotated and arranged in housing 100, upper rubbing card block 320 has at least two rubbing card positions unequal from its axis of rotation, when different rubbing card positions, the face that upper rubbing card block 320 cooperates with lower rubbing card block 310 is unequal to the distance of rotating shaft, drive upper rubbing card block 320 to rotate by height adjusting member 400, thereby switch upper rubbing card block 320 to cooperate with lower rubbing card block 310 at different rubbing card positions. Because upper rubbing card block 320 is rotated and arranged on housing 100, the outer peripheral surface of upper rubbing card block 320 can be arc surface also can be wavy surface or other irregular surface, as long as guarantee that upper rubbing card block 320 rotates to adjacent rubbing card position, the distance of upper rubbing card block 320 from the nearest point of lower rubbing card block 310 to lower rubbing card block 310 is unequal, namely upper rubbing card block 320 is when different rubbing card positions, the spacing of upper rubbing card block 320 and lower rubbing card block 310 changes, thereby connected spacing is adjusted.

[0044] In order to facilitate the manufacture and adjustment of the spacing between the upper rubbing block 320 and the lower rubbing block 310, the height adjustment member 400 includes an adjustment shaft 410 rotatably arranged on the housing 100, and the upper rubbing block 320 is an eccentric wheel, or the upper rubbing block 320 is a circular roller, but the height adjustment member 400 is eccentrically connected to the upper rubbing block 320, which makes the height adjustment member 400 rotate a certain angle, and the spacing between the lowest point of the upper rubbing block 320 and the lower rubbing block 310 changes, thereby playing the purpose of adjusting the spacing between the upper rubbing block 320 and the lower rubbing block 310. The upper rubbing block 320 of the above structure can achieve stepless adjustment when adjusting the spacing, and the spacing is continuously changing, which is more regular, and can facilitate users to quickly adjust to a suitable spacing distance.

[0045] Furthermore, in order to allow the adjustment shaft 410 to rotate stably, a rotation hole 130 is provided on the housing 100. The rotation hole 130 fixes the position of the adjustment shaft 410 and prevents the axis position of the adjustment shaft 410 from changing when the adjustment shaft 410 rotates. When the adjustment shaft 410 drives the upper card rubbing block 320 to rotate to a different card rubbing position, the current card rubbing position of the upper card rubbing block 320 needs to be fixed. When the playing cards pass through the upper card rubbing block 320, the friction between the playing cards and the upper card rubbing block 320 cannot drive the upper card rubbing block 320 to rotate. Therefore, the adjustment shaft 410 and the rotation hole 130 need to be closely matched, for example, there should be a certain amount of interference between the two.

[0046] In addition, a silicone gasket 500 can be placed between the adjustment shaft 410 and the inner wall of the rotary hole 130 to increase the friction between the adjustment shaft 410 and the rotary hole 130. Specifically, the silicone gasket 500 can be made into a cylindrical shape, wrapped around the adjustment shaft 410, and bonded to the adjustment shaft 410. The deformation of the silicone gasket 500 and the compression with the inner wall of the rotary hole 130 generate sufficient friction to fix the relative position of the adjustment shaft 410. Alternatively, the silicone gasket 500 can be bonded and fixed to the inner wall of the rotary hole 130, the adjustment shaft 410 inserted into the silicone gasket 500, and the adjustment shaft 410 rotates relative to the silicone gasket 500. The friction between the adjustment shaft 410 and the silicone gasket 500 fixes the relative position of the adjustment shaft 410.

[0047] In order to facilitate the rotation of the adjustment shaft 410, one end of the adjustment shaft 410 is exposed from the housing 100, and an adjustment notch 411 is provided at the exposed end. The user can insert a tool such as a screwdriver into the adjustment notch 411 to rotate the adjustment shaft 410 to adjust the card rubbing position of the upper card rubbing block 320. Of course, an adjustment hole can also be provided on the housing 100 corresponding to the end of the adjustment shaft 410. The end of the adjustment shaft 410 can be provided with an adjustment notch 411 or the end of the adjustment shaft 410 can be configured into a regular polygon. The user can align the screwdriver with the adjustment notch 411 or use a sleeve to fit the end of the adjustment shaft 410 to rotate the adjustment shaft 410 to adjust the card rubbing position of the upper card rubbing block 320.

[0048] On the basis of the foregoing embodiment, lower rubbing card block 310 is movably arranged on the housing 100, and the bottom of lower rubbing card block 310 and the housing 100 are provided with the elastic mechanism 600 that lower rubbing card block 310 is jacked up towards upper rubbing card block 320 directions, when playing cards pass through lower rubbing card block 310, if playing cards thickness is too thick, lower rubbing card block 310 can be squeezed, lower rubbing card block 310 will move downward after being squeezed, make between upper rubbing card block 320 and lower rubbing card block 310 enough gaps allow single playing cards to pass, and elastic mechanism 600 then starts the effect of resetting to the motion of lower rubbing card block 310. Lower rubbing card block 310 is arranged to movably set, so that the applicable scope of adjusting card mechanism 300 is further expanded, the adjustment of upper rubbing card block 320 can be the larger spacing adjustment of scope, and the adjustment of lower rubbing card block 310 then belongs to the fine adjustment to each playing card.

[0049] By setting a height adjustment member 400, the upper shuffling block 320 is driven to be located at shuffling positions of different heights, and the distance between the upper shuffling block 320 and the lower shuffling block 310 is quickly adjusted to adapt to playing cards of different thicknesses, thereby improving the applicability of the card dealing machine. In addition, the adjustment method is simple and reliable, and there is no need to disassemble the entire machine. The adjustment can be completed using simple tools such as a screwdriver.

[0050] Example 2

[0051] like Figure 6 This is a second embodiment of a card dealing machine of the present invention. The difference between this embodiment and the first embodiment is that the upper card rubbing block 320 is slidably arranged in the housing 100, and the height adjustment member 400 drives the upper card rubbing block 320 to slide, thereby adjusting the distance between the upper card rubbing block 320 and the lower card rubbing block 310.

[0052] The height adjustment member 400 includes an adjustment bolt 420 threadedly connected to the housing 100. The bottom end of the adjustment bolt 420 is rotatably connected to the upper shuffling block 320. The axial direction of the adjustment bolt 420 is parallel to the sliding direction of the upper shuffling block 320. By rotating the adjustment bolt 420, the upper shuffling block 320 is driven to slide in the vertical direction, thereby achieving the purpose of adjusting the distance between the upper shuffling block 320 and the lower shuffling block 310. To facilitate adjustment of the height adjustment member 400, a channel communicating with the top of the height adjustment member 400 can be opened on the housing 100 so that a tool such as an Allen wrench can be inserted into the top of the adjustment bolt 420 to drive the adjustment bolt 420 to rotate.

[0053] In addition to using the adjustment bolt 420, a handle can also be connected to the upper shuffling block 320, and the handle extends directly out of the housing 100. The user can slide the upper shuffling block 320 up and down by pulling the handle, thereby adjusting the distance between the upper shuffling block 320 and the lower shuffling block 310.
