However, the ball launching device in the prior art has the problem of fixed extrusion amount: the distance between the rubbing wheels of most traditional ball launching devices is fixed and cannot be adjusted, which limits their application to specific sizes or types of balls, lacking flexibility. SUMMARY

[0018] 4. Combination of lightness and durability: The friction wheel is composed of an aluminum core and an outer polyurethane coating layer, which not only reduces weight but also enhances wear resistance. The application of lightweight materials makes the entire device more portable, while the polyurethane coating layer provides good friction characteristics and a longer service life, which is particularly important for frequently used training equipment.

DETAILED DESCRIPTION

[0027] As Figures 1 to 6As shown, the utility model provides a kind of double friction wheel ball launching mechanism of adjustable extrusion amount, its main component includes frame and two friction wheel launching groups respectively arranged in the two sides of frame.Each friction wheel launching group contains a connecting frame, the connecting frame is installed with friction wheel and driving mechanism.Driving mechanism is transmission connection with the input shaft of friction wheel, to realize the rotating action of friction wheel.In order to adjust the extrusion amount of friction wheel to ball, connecting frame is also equipped with an extrusion amount adjusting plate, extrusion amount adjusting plate is installed on the input shaft of friction wheel, and extrusion amount is adjusted by changing the position of friction wheel fastened on connecting frame.

[0028] As Figure 2 And Figure 3 As shown, further, connecting frame is composed of mounting plate and connecting rod, wherein two mounting plates are fixed to the two ends of connecting rod.Extrusion amount adjusting plate is slidably connected to mounting plate by fastener (such as bolt), and mounting plate is provided with sliding groove, so that fastener can pass through extrusion amount adjusting plate and sliding groove, thereby fixing adjusting plate at desired position.This design allows user to conveniently adjust the distance between friction wheels to adapt to the launching requirements of different sizes or types of balls.

[0029] For driving mechanism, driving motor and transmission structure are combined. The output shaft of driving motor is connected to the input shaft of friction wheel through driving wheel, synchronous belt and driven wheel in transmission structure. Specifically, driving motor is installed on mounting plate, and its output shaft passes through mounting plate and is connected to driving wheel. Friction wheel is located between two mounting plates, and its input shaft passes through mounting plate and extrusion amount adjusting plate and is connected to driven wheel. Driving wheel and driven wheel are connected by synchronous belt for power transmission. This configuration ensures that driving motor can effectively transmit rotary force to friction wheel to realize ball launching.

[0030] To ensure the stability and efficiency of launching mechanism, two friction wheel launching groups are designed to be symmetrically arranged on both sides of frame. Such layout helps to maintain the balance of the entire device and also improves launching accuracy.

[0031] Friction wheel adopts concave profile surface design, aiming to better fit the surface of ball to increase the contact area and friction with the surface of ball, thereby improving launching efficiency and accuracy. In addition, friction wheel is composed of aluminum core and polyurethane coating layer wrapped outside, which can not only reduce weight but also enhance wear resistance and prolong service life.

[0032] As Figures 4 to 6 As shown, frame is composed of support outer frame and guide inner frame, and guide inner frame is fixedly installed inside support outer frame. Support outer frame is composed of connecting square tube, connecting plate and support frame, and these components are fixedly connected to each other by screws and other fasteners. Connecting square tube is arranged opposite to connecting plate, forming stable support structure.

[0033] The working principle of the utility model:

[0034] The whole launching mechanism is supported by a frame, and an extrusion amount adjusting plate is arranged on each friction wheel launching group and is installed on the connecting frame through fasteners (such as bolts), so that the user can loosen or tighten the fasteners to move the extrusion amount adjusting plate along the sliding groove on the mounting plate, thereby adjusting the distance between the friction wheels and achieving the purpose of adjusting the extrusion amount. The driving motor serves as a power source, and power is transmitted to the friction wheels through a transmission structure. When the ball is placed between the two friction wheels, the friction wheels start to rotate as the driving motor operates, and due to the friction, the ball is subjected to the combined action of the extrusion force and the friction force from the two friction wheels, and is gradually accelerated. When the speed of the ball is large enough, it will be out of the contact range of the friction wheels and fly out in the predetermined direction, completing the launching action.

[0035] The above-described embodiments only express several implementation manners of the utility model, and the description is relatively specific and detailed, but it cannot be understood as the limitation of the patent range of the utility model. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which all belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
