Description

Technical Field

[0001] This utility model belongs to the technical field of football training equipment, specifically relating to a football launcher for football training. Background Technology

[0002] In the field of football training, using ball-serving machines to replace manual serving is a common practice. Most ball-serving machines on the market currently achieve this by using friction between a friction roller and the football. For example, the football ball-serving machine with publication number CN206214715U uses a friction roller to perform the serving operation. However, this type of machine has significant drawbacks when used on wet fields. For instance, after rain, before placing the football into the machine, staff often need to wipe the surface to remove excess moisture to prevent a significant reduction in friction when it comes into contact with the friction roller, which can cause the ball to slip and result in poor overall serving performance.

[0003] While wiping away moisture from the surface of the soccer ball can increase the friction between the soccer ball and the friction roller to some extent and improve the serving effect, the residual moisture on the soccer ball will transfer to the friction roller when the soccer ball comes into contact with the friction roller. This will also cause the friction between the friction roller and the soccer ball to decrease, resulting in a poor serving effect. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a football launcher for football training, in order to solve the problem in the prior art that moisture adhering to the friction roller reduces the contact friction with the football, resulting in a poorer launching effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A football launcher for football training includes a football dehydration mechanism and a friction roller dehydration mechanism arranged in sequence, and both the football dehydration mechanism and the friction roller dehydration mechanism are provided with support legs;

[0007] The friction roller dewatering mechanism includes a mounting plate, a fixing plate at one end of the mounting plate, one end of the fixing plate being fixed to the mounting plate, and a launching tube at the middle of the other end of the fixing plate. The outer surface of the launching tube is fixed to the fixing plate. Drive motors are symmetrically arranged on both sides of the launching tube, and friction rollers are mounted on the output ends of each drive motor. A through-hole is provided on the launching tube, and part of the friction rollers are located within the through-hole. Slots are symmetrically arranged on the outer sides of each drive motor, one end of which is fixed to the mounting plate. A retaining plate is located within the slot, one end of which is located within the slot. A support plate is provided on the other end of the retaining plate. A screw is provided on the support plate, one end of which is fixed to the support plate, and the other end of which is provided with a limiting nut. A water-absorbing roller is sleeved on the screw between the limiting nut and the support plate, and the surface of the water-absorbing roller and the surface of the friction roller are in contact through a pressing mechanism.

[0008] Furthermore, the mounting plate is provided with symmetrical slide rails on both sides, and each slide rail is provided with a slider. Each slider is provided with a U-shaped baffle, and the two ends of the U-shaped baffle in the opening direction are respectively fixedly connected to the two sliders.

[0009] Furthermore, a front baffle is provided on the side of the U-shaped baffle away from the fixed plate. The front baffle is fixed to the U-shaped baffle, and the middle part of the front baffle is slidably connected to the launching tube.

[0010] Furthermore, the football dehydration mechanism includes an L-shaped support plate connected to the mounting plate, a drying box is provided on the L-shaped support plate, a hot air blower is provided at one end of the drying box, the output end of the hot air blower is connected to the interior of the drying box, one end of the drying box is fixed to the L-shaped support plate, and an end plate and an end cover are provided on the other end of the drying box, the end plate is fixed to the drying box.

[0011] Furthermore, a push plate is provided inside the other end of the drying box, and a slide rod is provided in the middle of the push plate. One end of the slide rod is fixed to the push plate, and the other end of the slide rod extends to the outside of the drying box. A stop block is provided on the other end of the slide rod, and a spring is provided between the stop block and the drying box. The two ends of the spring are respectively fixed to the stop block and the drying box.

[0012] Furthermore, the push plate is provided with several through holes.

[0013] Furthermore, the drying oven is equipped with an arc-shaped tube inside, one end of which is connected to the output end of the hot air blower, and the other end of which is equipped with a funnel end, which is located at the top of the drying oven.

[0014] Furthermore, the arc-shaped tube has a drainage hole on the lower outer surface of the end connected to the hot air blower.

[0015] Furthermore, each of the support legs is equipped with a universal wheel with a self-locking structure.

[0016] The beneficial effects of this utility model are as follows:

[0017] This technical solution uses a squeeze-type water-absorbing roller. When the friction roller rotates, it drives the water-absorbing roller to rotate as well. The water-absorbing roller then absorbs the moisture from the surface of the friction roller, ensuring that the surface of the friction roller is dry and improving the launching effect of the soccer ball.

[0028] like Figures 1-6 As shown, a football launcher for football training includes a football dehydration mechanism and a friction roller dehydration mechanism arranged in sequence, and both the football dehydration mechanism and the friction roller dehydration mechanism are provided with support legs 26.

[0029] The friction roller dewatering mechanism includes a mounting plate 1, support legs 26 fixed to the lower surface of the mounting plate 1, a fixing plate 2 on the upper surface near one end of the mounting plate 1, one end of the fixing plate 2 fixed to the mounting plate 1, and a launching tube 3 in the middle of the other end of the fixing plate 2. The outer surface of the launching tube 3 is fixed to the fixing plate 2. Drive motors 4 are symmetrically arranged on both sides of the launching tube 3. Friction rollers 5 are provided on the output ends of the drive motors 4. The launching tube 3 has a through-hole 6, and part of the friction rollers 5 are located in the through-hole 6. The outer sides are symmetrically provided with slots 7. One end of the slot 7 is fixed to the mounting plate 1. A card plate 8 is provided in the slot 7. One end of the card plate 8 is located in the slot 7. A support plate 9 is provided on the other end of the card plate 8. A screw 12 (with threads on the upper part of the screw 12) is provided on the support plate 9. One end of the screw 12 is fixed to the support plate 9. A limit nut 11 is provided on the other end of the screw 12. A water absorption roller 10 is sleeved on the screw 12 between the limit nut 11 and the support plate 9. The surface of the water absorption roller 10 and the surface of the friction roller 5 are in contact by pressure.

[0030] It should be noted that the connection between the drive motor 4 and the friction roller 5 to drive the friction rotation, as well as the method of powering the drive motor 4 with a battery or external power supply on the mounting plate 1, are existing technologies well known to those skilled in the art, and will not be elaborated further here.

[0031] The working principle of the above technical solution is as follows:

[0032] A soccer ball 29 is inserted into one end of the launching tube 3. The soccer ball 29 slides inside the launching tube 3 to the friction roller 5 (it is easy to understand that the launching tube 3 is set at an angle). As the friction roller 5 rotates at high speed under the drive of the drive motor 4, the two friction rollers 5 will squeeze the soccer ball 29 and shoot the soccer ball 29 out at high speed, realizing the projectile function of the soccer ball 29. When the friction roller 5 comes into contact with the soccer ball 29, the residual water on the soccer ball 29 will be transferred to the friction roller 5. Although the friction roller 5 can shake out a large amount of water during the rotation, there will always be moisture remaining on the surface of the friction roller 5, which will result in poor projectile effect of the soccer ball 29. In this application, by squeezing and setting the water-absorbing roller 10 (the surface is covered with water-absorbing material such as water-absorbing cloth or sponge layer), the rotation of the friction roller 5 will drive the water-absorbing roller 10 to rotate, and then the water-absorbing roller 10 will absorb the moisture on the surface of the friction roller 5, ensuring that the surface of the friction roller 5 is dry and improving the projectile effect of the soccer ball 29. It is easy to understand that the card plate 8 located in the card slot 7 can limit the rotation of the card plate 8. At the same time, it is also simple to install and disassemble. Just move the card plate 8 up and down in the card slot 7. Furthermore, the screw 12 can be used as an installation shaft. At the same time, the setting of the limit nut 11 also makes it easy to replace the water suction roller 10 on the screw 12.

[0033] In one feasible embodiment, slide rails 13 are symmetrically arranged on both sides of the mounting plate 1, and sliders 14 are provided in each slide rail 13. U-shaped baffles 15 are provided on the two sliders 14, and the two ends of the U-shaped baffles 15 in the opening direction are respectively fixedly connected to the two sliders 14. The U-shaped baffles 15 shield the friction roller 5 and the drive motor 4 from rain. At the same time, the arrangement of the sliders 14 allows the U-shaped baffles 15 to move laterally. Removing them exposes the water-absorbing roller 10, which facilitates the replacement of the water-absorbing roller 10 during use.

[0034] In one feasible embodiment, a front baffle 16 is provided on the side of the U-shaped baffle 15 away from the fixed plate 2. The front baffle 16 is fixed to the U-shaped baffle 15, and the middle part of the front baffle 16 is slidably connected to the launching tube 3. The front baffle 16 can cooperate with the fixed plate 2 to seal both ends of the U-shaped baffle, further improving the waterproof effect. Of course, it is easy to understand that rainwater may enter from the contact gaps of various components. First of all, the entry of a small amount of rainwater will not affect the use of components such as the friction roller 5 and the water absorption roller 10, because the two are relatively high, and a small amount of rainwater will not come into contact with them. At the same time, sealing strips can be set at the contact gaps to prevent water from entering. The sealing strips can be sealed by compression, which is existing technology and will not be described in detail here.

[0035] In one feasible embodiment, the football dehydration mechanism includes an L-shaped support plate 17 connected to the mounting plate 1, a drying chamber 18 mounted on the L-shaped support plate 17, a hot air blower 21 (with a heating wire installed on the air outlet pipe of the blower, as per prior art) at one end of the drying chamber 18, the output end of the hot air blower 21 communicating with the interior of the drying chamber 18, one end of the drying chamber 18 being fixed to the L-shaped support plate 17, and an end plate 19 and an end cover 20 mounted on the other end of the drying chamber 18, the end plate 19 being fixed to the drying chamber 18.

[0036] Several moist soccer balls 29 are placed in the drying chamber 18. Under the hot air blowing from the hot air blower 21, the large amount of moisture on the soccer balls 29 can be quickly evaporated, thus removing moisture from the surface of the soccer balls 29. Compared with the traditional method of wiping with an absorbent cloth, the cleaning efficiency is much higher. At the same time, when a soccer ball 29 is needed, it can be removed from the end cap 20. The remaining soccer balls 29 can be further dehydrated in the drying chamber 18. This setting allows for continuous soccer ball launching.

[0037] In one feasible embodiment, a push plate 22 is provided inside the other end of the drying chamber 18, and a slide rod 23 is provided in the middle of the push plate 22. One end of the slide rod 23 is fixed to the push plate 22, and the other end of the slide rod 23 extends to the outside of the drying chamber 18. A stop block 25 is provided on the other end of the slide rod 23. A spring 24 is provided between the stop block 25 and the drying chamber 18, and the two ends of the spring 24 are respectively fixed to the stop block 25 on the drying chamber 18.

[0038] By pressing the stop 25, the push plate 22 is moved, which in turn moves the internal soccer ball 29, thereby changing the contact surface between the soccer ball 29 and the hot air, thus avoiding the problem of poor moisture removal on the contact surface between the soccer ball 29 and other components.

[0039] In one feasible approach, the push plate 22 is provided with several through holes to improve air permeability, reduce wind pressure resistance during pushing, and also allow water to pass through. Of course, a drainage section can be provided on the bottom surface of the drying box 18 to facilitate water discharge.

[0040] In one feasible embodiment, the interior of the drying chamber 18 is provided with an arc-shaped tube 27, one end of which is connected to the output end of the hot air blower 21, and the other end of the arc-shaped tube 27 is provided with a funnel end 28, which is located at the top of the drying chamber 18.

[0041] It's easy to understand that because the temperature inside the drying oven 18 cannot be too high (temperature control can be achieved through existing technologies such as sensors, which will not be elaborated on further), the drying time for the soccer ball 29 inside is relatively long. During training, the soccer ball 29 needs to be continuously thrown. That is, the soccer ball 29 to be thrown can be placed inside the arc-shaped tube 27. Under the action of the hot air blower 21, the soccer ball 29 will be blown upwards from the bottom of the arc-shaped tube 27. The soccer ball 29 continuously rolls and moves upwards inside the arc-shaped tube 27, thus quickly removing most of the moisture from the soccer ball 29. Then it can be dried... The soccer ball 29 is taken out from the funnel end 28 and launched. It is easy to understand that the soccer ball 29 will float and turn inside the funnel end 28, thus quickly removing moisture and making it easy to pick up. Of course, the hot air blower 21 can work in a pulse mode, making the soccer ball 29 roll back and forth inside the arc tube 27, further improving the moisture removal effect. The remaining soccer balls 29 can be placed in the drying box 18 for drying (part of the heat output from the hot air blower 21 is discharged into the drying box 18). As for the air pressure of the hot air blower 21, it can be adjusted according to the actual situation, which will not be elaborated on here.

[0042] In one feasible approach, the arc-shaped pipe 27 has a drainage hole on the lower outer surface of the end connected to the hot air blower 21 to remove moisture from the arc-shaped pipe 27. Of course, it is preferable to discharge the moisture to the outside of the drying chamber 18 through a pipe rather than directly into the drying chamber 18.

[0043] In one feasible embodiment, the support leg 26 is equipped with casters with self-locking mechanisms, which facilitates movement and control of the launching direction of the soccer ball 29. At the same time, the height of the support leg 26 can be controlled to change the launching height of the soccer ball 29. The specific operation method can be selected according to the actual situation, and will not be elaborated on here.

[0044] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
