Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses a multi-ball launching device. (Refer to...) Figures 1-4 A multi-ball launching device includes a base 1, a ball outlet tube 2 fixedly connected to the top of the base 1, a fixed friction wheel 3 and an adjustable friction wheel 4 respectively arranged on both sides of the ball outlet tube 2, the bottom of the fixed friction wheel 3 being fixedly connected to the base 1, a first mounting plate 5 fixedly connected to one side of the base 1, a spacing adjustment push rod 6 fixedly connected to the surface of the first mounting plate 5, the output end of the spacing adjustment push rod 6 passing through the first mounting plate 5 and fixedly connected to the adjustable friction wheel 4, one end of the ball outlet tube 2 being fixedly connected to a ball inlet tube 7, and one side of the ball inlet tube 7 being fixedly connected to a ball outlet tube 7. A second mounting plate 8 is fixedly connected to the ball delivery push rod 9, and the output end of the ball delivery push rod 9 extends into the inner cavity of the ball inlet tube 7. By setting up a base 1, a ball outlet tube 2, a fixed friction wheel 3, an adjustable friction wheel 4, a first mounting plate 5, a spacing adjustment push rod 6, a ball inlet tube 7, a second mounting plate 8, a ball delivery push rod 9, and an opening 12, the distance between the fixed friction wheel 3 and the adjustable friction wheel 4 can be adjusted to launch balls of different sizes, and the rotation speed of the fixed friction wheel 3 and the adjustable friction wheel 4 can be adjusted to launch small balls of different weights.

[0018] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A mounting plate 10 is fixedly fitted on the surface of the ball outlet tube 2. Four mounting holes 11 are opened on one side of the mounting plate 10. One side of the fixed friction wheel 3 and the adjusting friction wheel 4 both penetrate into the inner cavity of the ball outlet tube 2. An opening 12 is opened on the surface of the ball outlet tube 2 to cooperate with the fixed friction wheel 3 and the adjusting friction wheel 4. By setting the mounting plate 10 and the mounting holes 11, it is easy to connect the ball outlet tube 2 to the external pipeline. By setting the opening 12, it is easy to use the fixed friction wheel 3 and the adjusting friction wheel 4. Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The ball-in-the-hole tube 7 is a three-way tube. The surface of the adjusting friction wheel 4 is slidably connected to the base 1. An elastic rubber ring is fixedly connected to the inner wall of the ball-in-the-hole tube 7. Slider 13 is fixedly connected to both sides of the adjusting friction wheel 4. The inner wall of the base 1 is provided with a groove 14 that works with the slider 13. One side of the slider 13 extends into the inner cavity of the groove 14. By setting the three-way tube, it is easy to put the ball in and push the ball. By setting the slider 13 and the groove 14, the stability of the movement of the adjusting friction wheel 4 can be improved. By setting the elastic rubber ring, the ball can only enter the friction launch area under the action of the push rod, and will not roll into the launch area under the action of gravity when the launch port is facing down, causing the launch to be uncontrollable. Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The surface of the first mounting plate 5 is fixedly connected to the base 1 by the first bolt, and the surface of the second mounting plate 8 is fixedly connected to the ball tube 7 by the second bolt.

By setting the second bolt, the connection between the second mounting plate 8 and the ball tube 7 can be facilitated. By setting the connection holes 15, the connection between the ball tube 7 and the external ball passage pipe can be facilitated.

[0019] Working principle: The ball to be launched is inserted through the top of the ball inlet tube 7. The drive device makes the fixed friction wheel 3 and the adjusting friction wheel 4 rotate at high speed. The ball delivery push rod 9 is opened to push the ball and make it move. When the ball comes into contact with the high-speed rotating fixed friction wheel 3 and the adjusting friction wheel 4, it is accelerated and launched under the action of friction. The adjusting friction wheel 4 can be moved by opening the distance adjustment push rod 6. By adjusting the distance between the fixed friction wheel 3 and the adjusting friction wheel 4, balls of different sizes can be launched. By adjusting the rotation speed of the fixed friction wheel 3 and the adjusting friction wheel 4, balls of different weights can be launched.
