Detailed Implementation

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0029] Example 1.

[0030] See Figures 1-6 The belt conveyor mechanism of the poker dealing machine in this embodiment includes a mounting frame 1 and a belt 2. The mounting frame 1 is detachably mounted on the frame of the poker dealing machine. The mounting frame 1 includes two parallel side plates 11 connected by bolts 12 to form a conveying space 13 between the two side plates 11. The belt 2 is rotatably mounted in the conveying space 13. The frame is provided with a number of rows of wheels 31 arranged in a straight line at equal intervals. The rows of wheels 31 are located directly below the belt 2 and there is a gap 21 between them for the poker cards to pass through. Both sides of the belt 2 are provided with a number of actuating parts for pushing the poker cards into the chamber of the poker dealing machine. The actuating parts on the same side correspond one-to-one with the chamber and are arranged at equal intervals along the conveying trajectory of the poker cards. The mounting frame 1 is provided with a drive mechanism 4 for driving the belt 2 to rotate relative to the frame and a tensioning mechanism 5 for adjusting the tension of the belt 2.

[0031] The actuating element is an elastic strip 32, which can bend elastically. The upper end of the elastic strip 32 is embedded and fixed on the side plate 11, and its lower end is located on the conveying track of the playing cards. The elastic strip 32 can be made of elastic materials such as rubber, polyurethane (PU), or silicone.

[0032] When the card dealing machine is distributing cards, the cards are moved from the card box into the gap 21 between the belt 2 and the pulley 31. At this time, the belt 2, which is rotating under the drive of the drive mechanism 4, moves the cards due to the friction between them after contacting the cards. The cards pass through the gap 21 between the pulley 31 and the belt 2 and move towards the top of the compartment. During this process, the cards will press against the elastic strip 32 and bend it, causing the elastic strip 32 to move away from the movement trajectory of the cards.

[0033] When the hatch on the compartment is closed, the playing cards pass over the hatch and are conveyed to the gap 21 between the next pulley 31 and the belt 2. When the playing cards are released from their contact with the elastic strip 32, the elastic strip 32 returns to its original state.

[0034] When the hatch on the compartment is open, the playing cards are pressed into the compartment by the force of the elastic strip 32 returning to its original shape, leaving enough space at the top of the compartment for the next playing card to enter.

[0035] SeeFigures 1-5 The driving mechanism 4 includes a transmission roller 41 and a first limiting roller 42. The transmission roller 41 is rotatably mounted on the mounting frame 1. The mounting frame 1 is equipped with a motor 43 for driving the transmission roller 41 to rotate relative to the mounting frame 1. The belt 2 is wound around the transmission roller 41 and the first limiting roller 42. A plurality of second limiting rollers 44 are provided between the transmission roller 41 and the first limiting roller 42. The first limiting roller 42 and the second limiting roller 44 are both rotatably connected to the mounting frame 1. The structure of the second limiting roller 44 is the same as that of the first limiting roller 42, and both correspond one-to-one with the roller cylinders 33 on each row of wheels 31. The second limiting roller 44 abuts against the belt 2 from top to bottom.

[0036] During the process of the motor 43 driving the transmission roller 41 to rotate, due to the friction between the transmission roller 41 and the belt 2 and the rotation path of the belt 2 formed by the transmission roller 41, the first limit roller 42 and the second limit roller 44, the transmission roller 41 can drive the belt 2 to rotate, thereby ensuring the conveying effect of the belt 2 on the playing cards.

[0037] In this embodiment, there are two roller cylinders 33 on each of the rollers 31, and the roller cylinders 33 on each roller 31 are on the same horizontal plane.

[0038] See Figure 3 , Figure 4 The first limiting roller 42 and the second limiting roller 44 each include a first mounting shaft 61 and a first sleeve 62. Both ends of the first mounting shaft 61 are fixedly connected to the mounting frame 1 by screws. The first sleeve 62 is sleeved on the first mounting shaft 61 and is rotatable. Through the structural arrangement of the first limiting roller 42 and the second limiting roller 44, the installation of the first limiting roller 42 and the second limiting roller 44 on the mounting frame 1 is facilitated, while also ensuring that the first limiting roller 42 and the second limiting roller 44 can rotate relative to the mounting frame 1, thereby ensuring the smooth rotation of the belt 2 relative to the mounting frame 1.

[0039] See Figure 5 , Figure 6 The tensioning mechanism 5 includes a first bracket 51 and a second bracket 52, both of which are L-shaped. One end of the first bracket 51 is hinged to the mounting frame 1. An adjusting roller 53 for the belt 2 to be wound is rotatably connected to the first bracket 51. A reversing roller 54 for the belt 2 to be wound is arranged between the first limiting roller 42, the adjusting roller 53, the transmission roller 41, and the second limiting roller 44 in sequence. The reversing roller 54 is rotatably connected to the mounting frame 1. One end of the second bracket 52 is fixedly connected to the mounting frame 1. A tension spring 55 is provided between the other ends of the first bracket 51 and the second bracket 52. The two ends of the tension spring 55 are hooked onto the first bracket 51 and the second bracket 52, respectively.

[0040] By adjusting the settings of the adjusting roller 53 and the direction-changing roller 54, the effect of winding the longer belt 2 on the transmission roller 41 and the first limiting roller 42 is achieved, and in combination with the connecting structure settings of the first support 51 and the second support 52 on the mounting rack 1 and the setting of the tension spring 55 between the two, the position of the adjusting roller 53 on the mounting rack 1 can be changed, and when the first support 51 is pulled by the tension spring 55, the adjusting roller 53 is always pressed against the belt 2, ensuring the tensioning degree of the belt 2 winding, thereby ensuring the effectiveness of the driving mechanism 4 driving the belt 2 to rotate while also reducing the risk of the belt 2 falling off.

[0041] Referring to Figure 5 , Figure 6 , the adjusting roller 53 and the direction-changing roller 54 each include a second mounting shaft 71 and a second sleeve 72, one end of the second mounting shaft 71 on the adjusting roller 53 is fixedly connected to the first support 51 by a screw, both ends of the second mounting shaft 71 on the direction-changing roller 54 are fixedly connected to the mounting rack 1 by a screw, the second sleeve 72 is sleeved on the second mounting shaft 71 and can rotate, and limiting pieces 73 for preventing the belt 2 from disengaging from the second sleeve 72 are arranged on both ends of the second sleeve 72, and the limiting pieces 73 are arranged perpendicularly to the second sleeve 72. Through the structural settings of the adjusting roller 53 and the direction-changing roller 54, the installation of the adjusting roller 53 on the first support 51 and the direction-changing roller 54 on the mounting rack 1 is facilitated, and at the same time, it is ensured that the adjusting roller 53 and the direction-changing roller 54 can rotate relative to the mounting rack 1, thereby ensuring the smoothness of the rotation of the belt 2 relative to the mounting rack 1, and also reducing the impact on the rotation of the belt 2 when the adjusting roller 53 moves to adjust the tensioning degree of the belt 2.

[0042] Embodiment Two.

[0043] Referring to Figure 7 , the structure of the present embodiment is basically the same as that of the belt transmission mechanism of the card dealing machine of Embodiment One, except that the toggle member is a metal hanging piece 34, the upper end of which is hinged to the side plate 11 and the lower end of which is located on the conveying track of the playing cards.

[0044] When the playing cards are conveyed in a straight line under the driving of the rotating belt 2, the hatch door on the cabin is in a closed state, the playing cards pass through the hatch door and are conveyed into the gap 21 between the next row wheel 31 and the belt 2, and in this process, the playing cards push the metal hanging piece 34 to rotate relative to the side plate 11, the metal hanging piece 34 is flipped up and moves away from the conveying track of the playing cards, and after the playing cards disengage from the metal hanging piece 34, the metal hanging piece 34 is flipped down and reset under the action of gravity.

[0045] When the hatch on the cabin is in the open state, the playing cards can be pressed into the cabin under the action of the metal tab 34 being flipped down and reset, and the top of the cabin is left with enough space for the next playing card to enter.

[0046] The above described in the specification of the present application is only an example of the present application. The skilled in the art of the present application can make various modifications or supplements or adopt similar ways to replace the described specific embodiments, as long as it does not deviate from the content of the specification of the present application or beyond the scope defined by the claims, should belong to the protection scope of the present application.
