Description

Technical Field

[0001] The present invention relates to the technical field of training equipment, and particularly to a multifunctional handball launcher. Background Art

[0002] Handball is a ball sport that originated in Germany. Basically, handball is like a mixture of football and rugby. At the same time, some rules of handball evolved from the rules of basketball.

[0003] Before starting a handball game, it is necessary to apply a ball glue made of rosin on the surface of the handball to enhance the firmness of holding the ball with one hand. After the handball game ends, it is necessary to remove the ball glue on the surface of the handball before storing the handball.

[0004] Currently, there are already some existing technologies that can conduct ball launching exercises. For example, the patent publication number is CN114768229A. Its main technical means is to drive a hitting piston through a hitting mechanism to shoot the ball out of the ball outlet channel. At the same time, by combining a compression spring to adjust the hitting force, the flying speed of the ball can be adjusted. After analysis, the disadvantages of this technical solution are that when conducting handball training, it is impossible to apply glue to the handball to be launched, and when the launcher retrieves the handball, it is also impossible to remove the dirty ball glue on the surface of the handball. Direct storage will cause the ball glue on the surface of the handball to dry and harden, thus affecting the use of glue application next time. Based on this, the present invention provides a multifunctional handball launcher with a simple and ingenious structure, which can automatically apply glue to the surface of the handball before launching and automatically remove the ball glue on its surface when collecting the handball. Summary of the Invention

[0005] The purpose of the present invention is to provide a multifunctional handball launcher for the deficiencies of the existing technology, so as to solve the technical problem that it is impossible to automatically apply glue to the handball to be launched and impossible to remove the ball glue on its surface when retrieving the handball.

[0006] The purpose of the present invention can be achieved through the following technical solutions: A multifunctional handball launcher includes a base and a storage box. A launching assembly for launching handballs is arranged on the base. A degumming box for degumming is connected to the top of the storage box. A degumming assembly is arranged in the degumming box, and a collecting hopper is connected to its top. The bottom of the storage box is connected to a glue application box through a first ball delivery tube. Ball releasing assemblies for intermittently delivering balls are arranged at the bottom of the collecting hopper and the bottom of the first ball delivery tube. A glue application assembly is arranged in the glue application box, and its bottom is connected to the feeding port of the launching assembly through a second ball delivery tube.

[0007] As a further solution of the present invention: The launching assembly includes: A launching tube is installed on a base and driven to rotate by an output source arranged inside the base. The feeding port of the launching tube is connected to a second ball feeding tube, and only a single handball can pass through the launching tube; and A piston is slidably installed inside the launching tube and driven by a first driving source installed on the launching tube.

[0008] As a further solution of the present invention: The launching port of the launching tube is threadedly connected with a rubber increasing tube, and ball glue is smeared on the inner wall of the rubber increasing tube.

[0009] As a further solution of the present invention: The glue removing assembly includes: Rubber knives. Two rubber knives are symmetrically arranged and respectively slidably matched with two driving boxes. A first power source for driving the rubber knives to rotate 180° is arranged inside the driving boxes, and a second driving source for driving the two driving boxes to move towards each other or away from each other is arranged inside the glue removing box; When the two driving boxes move towards each other until the two rubber knives are spliced, both rubber knives are in contact with the surface of the handball; Clamping balls. Two clamping balls are respectively rotatably installed on the opposite surfaces of the two driving boxes, and a second power source for driving the clamping balls is arranged inside the driving boxes; When the two driving boxes move towards each other until the two rubber knives are spliced, both clamping balls are in contact with the surface of the handball; When the second power source drives the two clamping balls to rotate in the same direction, the two clamping balls drive the clamped handball to turn over; and Rubber blocks. A plurality of rubber blocks are arranged in a circular pattern on the bottom plate of the glue removing box, and the plurality of rubber blocks enclose a bearing cavity for bearing the handball; In the free state, several rubber blocks are spliced with each other. When the rubber blocks are stressed and deformed, there is a gap between adjacent two rubber blocks, and the glue removing box is communicated with the storage box.

[0010] As a further solution of the present invention: The two clamping balls respectively penetrate through the opposite surfaces of the two driving boxes, and a scraping glue ring coaxial with the clamping balls is respectively fixed on the opposite surfaces of the two driving boxes, and the scraping glue ring is in contact with the surface of the clamping balls.

[0011] As a further solution of the present invention: A push rod is slidably installed on the top plate of the glue removing box above the bearing cavity, and a third power source for driving the push rod to lift and lower is arranged; When the third power source drives the push rod to descend, the push rod pushes the handball downward to squeeze the plurality of rubber blocks to deform, and passes through the gaps between the plurality of rubber blocks and enters the storage box.

[0012] As a further solution of the present invention: The glue removing assembly further includes two arc-shaped boxes respectively arranged on both sides of the handball on the bearing cavity. A plurality of nozzles facing the surface of the handball on the bearing cavity are connected to each arc-shaped box, and the two arc-shaped boxes are connected to a blower through a hot air pipe.

[0013] As a further solution of the present invention: the ball placing assembly includes a ball blocking plate and a third driving source for driving it to perform reciprocating linear motion. The ball blocking plates of the two ball placing assemblies are respectively in sliding fit with the bottom of the collecting hopper and the bottom of the first ball feeding cylinder, and the ball blocking plate penetrates through the collecting hopper and the first ball feeding cylinder. When the ball blocking plates of the two ball placing assemblies are respectively located in the collecting hopper and the first ball feeding cylinder, the ball blocking plate blocks the handballs above it from falling. When the ball blocking plate slides to allow the handballs above it to fall, the third driving source immediately drives the ball blocking plate to reset to block the continued fall of the next handball.

[0014] As a further solution of the present invention: the glue coating assembly includes: Glue coating shells, two of the glue coating shells are respectively arranged on both sides of the second ball feeding cylinder and are located in the glue coating box. Glue for balls is covered on the opposite surfaces of the two glue coating shells; Slide rods, two of the slide rods are both slidably installed in the glue coating box and are respectively connected to the two glue coating shells. The slide rods are driven by a fourth driving source installed in the glue coating box to perform reciprocating linear motion, and the slide rods penetrate through the side wall of the glue coating box; and A transmission assembly, which is installed on the outer wall of the glue coating box and is connected to the slide rod. The second ball feeding cylinder and the glue coating box are coaxially arranged, and a sealing plate is provided at the connection between the two. The sealing plate is connected to the transmission assembly. The glue coating box is a conical cavity, and the cross-section of its bottom plate is conical, and the tip of the cone is the sealing plate. When the fourth driving source drives the two slide rods to move towards each other until the two glue coating shells are spliced, both of the glue coating shells are in contact with the surface of the handball on the sealing plate. When the fourth driving source drives the two slide rods to move away from each other, the two glue coating shells move away from each other synchronously, and the slide rod drives the sealing plate to translate through the transmission assembly, so that the glue coating box and the second ball feeding cylinder are in a communicating state.

[0015] As a further solution of the present invention: the glue coating assembly further includes converging plates. Two converging plates are respectively fixed on both sides of the glue coating shell, and the converging plates are arranged obliquely. The included angle between the two converging plates on the same side of the two glue coating shells is an acute angle.

[0016] The beneficial effects of the present invention: (1) In the present invention, the ball feeding assembly is used to intermittently convey the handballs in the collection hopper to the degumming box. After the handballs enter the degumming box, the degumming assembly removes the glue from them, and after degumming, the handballs are pushed into the storage box for storage. The ball feeding assembly in the first ball feeding cylinder intermittently conveys the clean handballs from the storage box to the glue coating box. The handballs entering the glue coating box are coated with glue by the glue coating assembly, and after the glue coating is completed, they enter the second ball feeding cylinder. Multiple handballs with glue are arranged in the second ball feeding cylinder, and the lowermost handball is located at the feeding port of the launching assembly. After the launching assembly launches the handball, the adjacent handball above it enters the feeding port of the launching assembly and waits to be launched. This process repeats to achieve the launching during handball training. It can also automatically remove the glue on the surface of the recycled handballs and automatically coat the glue before launching when recycling the handballs, avoiding manual glue coating and degumming by athletes and improving the convenience of using the launcher. (2) In the present invention, during the process of the handball shooting out from the launching end of the launching cylinder, the handball will adhere to the glue on the inner wall of the glue increasing cylinder when moving inside it, so as to supplement the glue on the surface of the handball and make up for the scraping of the glue on the surface of the handball from the time of glue coating to before launching, ensuring that the surface of the handball can be evenly covered with glue. (3) In the present invention, after the handball rolls into the bearing cavity, the second driving source drives the two driving boxes to move towards each other until the two rubber knives are spliced. At this time, both rubber knives are in contact with the surface of the handball. Subsequently, the first power source drives the rubber knife to rotate 180°, so as to scrape off the glue on half of the surface area of the handball. Then, the second power source drives the two clamping balls to rotate in the same direction and rotate 180°, so that the two clamping balls drive the clamped handball to turn over. Subsequently, the first power source drives the rubber knife to rotate 180° in the reverse direction to reset. During this process, the glue on the other half of the surface area of the handball can be removed, so as to fully scrape off the residual glue on the surface of the handball. (4) In the present invention, after the rubber knife rotates 180° multiple times, the residual glue on the surface of the handball is completely scraped off. Subsequently, the third power source drives the push rod to descend, and at the same time, the second power source synchronously drives the two clamping balls to rotate in the reverse direction to drive the handball to move downward, and cooperate with the push of the push rod to ensure that the handball can squeeze several rubber blocks to deform, and then pass through the gaps between several rubber blocks and enter the storage box, thus realizing the collection of clean handballs after degumming. (5) In the present invention, the clean handballs falling into the glue coating box roll along its bottom surface to the sealing plate. Subsequently, when the fourth driving source drives the two sliding rods to move towards each other until the two glue coating shells are spliced, the two glue coating shells clamp the handball on the sealing plate and coat the glue on the surface of the handball. Then, the fourth driving source drives the two sliding rods to move away from each other, and the two glue coating shells move away from each other synchronously. And the sliding rod drives the sealing plate to translate through the transmission assembly, so that the glue coating box and the second ball feeding cylinder are in a communicating state. When the glue coating shell slides away from the handball, the handball can enter the second ball feeding cylinder and finally reach the feeding port of the launching assembly to wait for launching.

Detailed Embodiments

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-7As shown in the figure, the present invention is a multi-functional handball launcher, including a base 1 and a storage box 3. A launching assembly 2 for launching handballs is provided on the base 1. A degumming box 4 for degumming is connected to the top of the storage box 3. A degumming assembly is provided in the degumming box 4, and a collecting hopper 14 is connected to the top thereof. The bottom of the storage box 3 is connected to a glue coating box 15 through a first ball feeding tube 16. Ball releasing assemblies 18 for intermittently feeding balls are provided at the bottom of the collecting hopper 14 and the bottom of the first ball feeding tube 16. A glue coating assembly is provided in the glue coating box 15, and its bottom is connected to the feeding port of the launching assembly 2 through a second ball feeding tube 17.

[0022] In a case of this embodiment, the diameters of the bottom of the collecting hopper 14, the first ball feeding tube 16, and the second ball feeding tube 17 are only large enough for a single handball to pass through.

[0023] In actual application of this embodiment, after the handball training is over, several handballs are placed into the collecting hopper 14. The ball releasing assembly 18 enables the handballs in the collecting hopper 14 to be intermittently conveyed to the degumming box 4. After the handballs enter the degumming box 4, the degumming assembly degums them, and after degumming, the handballs are pushed into the storage box 3 for storage. Subsequently, the ball releasing assembly 18 in the collecting hopper 14 conveys another handball to the degumming box 4 again, and the above process is repeated. Finally, the storage box 3 stores multiple clean handballs after degumming for training use. When starting the handball training, the ball releasing assembly 18 in the first ball feeding tube 16 enables the storage box 3 to intermittently convey clean handballs to the glue coating box 15. The handballs entering the glue coating box 15 are coated with ball glue by the glue coating assembly, and after the glue coating is completed, they enter the second ball feeding tube 17. Multiple handballs coated with glue are arranged in the second ball feeding tube 17, and the lowermost handball is located at the feeding port of the launching assembly 2. After the launching assembly 2 launches this handball, the adjacent handball above it enters the feeding port of the launching assembly 2 and waits to be launched. In this way, the launching during handball training is realized, and when recycling handballs, the surface of the recycled handballs can be automatically degummed, and glue can be automatically coated before launching, avoiding manual glue coating and degumming by athletes and improving the convenience of using the launcher.

[0024] As Figures 1-2 shown, as a preferred embodiment of the present invention, the launching assembly 2 includes: A launching tube 201, which is installed on the base 1 and is driven to rotate by an output source provided in the base 1. The feeding port of the launching tube 201 is connected to the second ball feeding tube 17; and A piston 202, which is slidably installed in the launching tube 201 and is driven by a first driving source 203 installed on the launching tube 201.

[0025] In a case of this embodiment, the piston 202 is connected to the inner wall of the launching tube 201 through a spring.

[0026] The output source can be a motor assembly, or a gear assembly or a pulley assembly driven by a motor, as long as it can make the launching tube 201 rotate. This embodiment does not specifically limit it here; the first driving source 203 can select components such as a hydraulic cylinder or a pneumatic cylinder, and can also select other mechanisms that can achieve linear motion. This embodiment does not specifically limit it here.

[0027] In the actual application of this embodiment, when the output source drives the launching tube 201 to rotate, it can synchronously rotate the storage box 3, the degumming box 4, the collection hopper 14 and the glue application box 15 above to adjust the launching direction of the handball; after the first driving source 203 drives the piston 202 to move away from the launching end of the launching tube 201, the spring is compressed, and the elastic force of the spring can cooperate to shoot the handball out from the launching end of the launching tube 201.

[0028] As Figure 2 shown, as a preferred embodiment of the present invention, a glue increasing tube 204 is threadedly connected to the launching port of the launching tube 201, and ball glue is smeared on the inner wall of the glue increasing tube 204.

[0029] In one case of this embodiment, only a single handball can pass through the glue increasing tube 204.

[0030] In the actual application of this embodiment, during the process of the handball being shot out from the launching end of the launching tube 201, the handball will be contaminated with the ball glue on its inner wall when moving in the glue increasing tube 204, so as to supplement the ball glue on the surface of the handball, make up for the scraping of the ball glue on the surface of the handball after smearing the ball glue until before launching, and ensure that the surface of the handball can be evenly covered with ball glue.

[0031] As Figures 1-6 shown, as a preferred embodiment of the present invention, the degumming assembly includes: Rubber knives 5, the two rubber knives 5 are symmetrically arranged and are respectively slidably matched with two driving boxes 6. A first power source for driving the rubber knives 5 to rotate 180° is arranged in the driving box 6, and a second driving source 10 for driving the two driving boxes 6 to move towards or away from each other is arranged in the degumming box 4; when the two driving boxes 6 move towards each other until the two rubber knives 5 are spliced, both rubber knives 5 are in contact with the surface of the handball; Clamping balls 7, two clamping balls 7 are respectively rotatably installed on the opposite surfaces of the two driving boxes 6, and a second power source for driving the clamping balls 7 is arranged in the driving box 6; when the two driving boxes 6 move towards each other until the two rubber knives 5 are spliced, both clamping balls 7 are in contact with the surface of the handball; when the second power source drives the two clamping balls 7 to rotate in the same direction, the two clamping balls 7 drive the clamped handball to turn over; and Rubber blocks 8. A plurality of rubber blocks 8 arranged in a circular pattern are provided on the bottom plate of the rubber removing box 4, and the plurality of rubber blocks 8 enclose a bearing cavity for bearing the handball. In the free state, several rubber blocks 8 are spliced together. When the rubber blocks 8 are deformed by force, there is a gap between two adjacent rubber blocks 8, and the rubber removing box 4 is communicated with the storage box 3.

[0032] In one case of this embodiment, the first power source can be an encoder cooperating with an output motor to drive the rubber knife 5 to rotate 180°, and after rotating 180°, it rotates in the reverse direction to reset. The first power source can also be other components that can realize the half - cycle reciprocating rotation of the rubber knife 5, which is not limited herein; the second driving source 10 can be a hydraulic cylinder, a pneumatic cylinder and other components, and can also be other mechanisms that can realize linear motion, which is not specifically limited in this embodiment; the second power source can be a motor assembly, or a gear assembly or a pulley assembly driven by a motor, as long as it can make the clamping ball 7 rotate, which is not specifically limited in this embodiment.

[0033] It should be noted that the rubber removing box 4 is a conical cavity, the cross - section of its bottom plate is conical, and the tip of the cone is the bearing cavity. The bearing cavity is Figure 5 as shown, a sunken spherical surface lower than the height of the surrounding plane. The handball falling into the rubber removing box 4 will roll along the bottom plate of the rubber removing box 4 to the bearing cavity.

[0034] In the actual application of this embodiment, in the initial state, the distance between the two rubber knives 5 is in the maximum state and is located on both sides of the bearing cavity. After the handball rolls into the bearing cavity, the second driving source 10 drives the two driving boxes 6 to move towards each other until the two rubber knives 5 are spliced. At this time, both rubber knives 5 are in contact with the surface of the handball. Subsequently, the first power source drives the rubber knife 5 to rotate 180° to scrape the ball glue on half of the surface area of the handball. Then, the second power source drives the two clamping balls 7 to rotate in the same direction and rotate 180° so that the two clamping balls 7 drive the clamped handball to turn over. Subsequently, the first power source drives the rubber knife 5 to rotate 180° in the reverse direction to reset. During this process, the ball glue on the other half of the surface area of the handball can be removed to fully scrape the residual ball glue on the surface of the handball.

[0035] As Figures 4-5 shown, as a preferred embodiment of the present invention, the two clamping balls 7 respectively penetrate through the opposite surfaces of the two driving boxes 6, and a scraping glue ring 9 co - axially arranged with the clamping ball 7 is fixed on each of the opposite surfaces of the two driving boxes 6. The scraping glue ring 9 is in contact with the surface of the clamping ball 7.

[0036] In the actual application of this embodiment, during the rotation of the clamping ball 7, the scraping glue ring 9 will remove the ball glue adhered to its surface to ensure that it can effectively scrape the ball glue on the surface of the handball subsequently.

[0037] As Figure 4 shown, as a preferred embodiment of the present invention, a push rod 25 located above the bearing cavity is slidably installed on the top plate of the degumming box 4, and a third power source for driving the lifting of the push rod 25 is provided; when the third power source drives the push rod 25 to descend, the push rod 25 pushes the handball downward to squeeze a plurality of rubber blocks 8 to deform, and passes through the gaps between the plurality of rubber blocks 8 and enters the storage box 3.

[0038] In one case of this embodiment, the third power source can be selected from components such as hydraulic cylinders and air cylinders, and other mechanisms capable of realizing linear motion can also be selected. This embodiment does not make specific limitations here.

[0039] It should be noted that when the third power source drives the push rod 25 to descend, the second power source synchronously drives the two clamping balls 7 to rotate in opposite directions, and the rotation central axis of the clamping balls 7 is vertically arranged with the rotation central axis of the rubber knife 5. When the two clamping balls 7 rotate in opposite directions, they can drive the handball to move downward.

[0040] In the actual application of this embodiment, after the rubber knife 5 rotates 180° multiple times, the residual ball glue on the surface of the handball is scraped clean. Subsequently, the third power source drives the push rod 25 to descend, and at the same time, the second power source synchronously drives the two clamping balls 7 to rotate in opposite directions to drive the handball to move downward, and cooperate with the push of the push rod 25 to ensure that the handball can squeeze a number of rubber blocks 8 to deform, and then pass through the gaps between the number of rubber blocks 8 and enter the storage box 3, so as to realize the collection of the clean handball after degumming.

[0041] As Figures 4-5 shown, as a preferred embodiment of the present invention, the degumming assembly further includes two arc-shaped boxes 11 respectively arranged on both sides of the handball above the bearing cavity. A number of nozzles 12 facing the surface of the handball above the bearing cavity are connected to each arc-shaped box 11, and the two arc-shaped boxes 11 are connected to a blower through a hot air pipe 13.

[0042] In the actual application of this embodiment, during the process of the rubber knife 5 rotating for scraping glue, the nozzles 12 continuously spray hot air on the surface of the handball to accelerate the melting of the ball glue, so as to improve the convenience of scraping the ball glue and further improve the scraping efficiency.

[0043] As Figures 1-6As shown, as a preferred embodiment of the present invention, the ball - releasing assembly 18 includes a ball - blocking plate 1801 and a third driving source 1802 for driving it to perform reciprocating linear motion. The ball - blocking plates 1801 of the two ball - releasing assemblies 18 are respectively in sliding fit with the bottom of the collection hopper 14 and the bottom of the first ball - feeding cylinder 16, and the ball - blocking plate 1801 penetrates through the collection hopper 14 and the first ball - feeding cylinder 16. When the ball - blocking plates 1801 of the two ball - releasing assemblies 18 are respectively located inside the collection hopper 14 and the first ball - feeding cylinder 16, the ball - blocking plate 1801 blocks the handballs above it from falling. When the ball - blocking plate 1801 slides to allow the handballs above it to fall, the third driving source 1802 immediately drives the ball - blocking plate 1801 to reset to block the continued falling of the next handball.

[0044] In one case of this embodiment, the third driving source 1802 can be components such as hydraulic cylinders, air cylinders, etc., or other mechanisms capable of realizing linear motion. This embodiment does not make specific limitations here.

[0045] As Figures 1-7 shown, as a preferred embodiment of the present invention, the glue - applying assembly includes: Glue - applying shells 19, the two glue - applying shells 19 are respectively arranged on both sides of the second ball - feeding cylinder 17 and are located inside the glue - applying box 15. Ball glue is covered on the opposite surfaces of the two glue - applying shells 19; Slide rods 21, the two slide rods 21 are both slidably installed inside the glue - applying box 15 and are respectively connected to the two glue - applying shells 19. The slide rods 21 are driven by a fourth driving source 20 installed inside the glue - applying box 15 to perform reciprocating linear motion, and the slide rods 21 penetrate through the side wall of the glue - applying box 15; and A transmission assembly 22, which is installed on the outer wall of the glue - applying box 15 and is connected to the slide rods 21. The second ball - feeding cylinder 17 and the glue - applying box 15 are coaxially arranged, and a sealing plate 23 is provided at the connection between the two. The sealing plate 23 is connected to the transmission assembly 22. The glue - applying box 15 is a conical cavity, the cross - section of its bottom plate is conical, and the tip of the cone is the sealing plate 23. When the fourth driving source 20 drives the two slide rods 21 to move towards each other until the two glue - applying shells 19 are spliced, both of the two glue - applying shells 19 are in contact with the surface of the handball on the sealing plate 23. When the fourth driving source 20 drives the two slide rods 21 to move away from each other, the two glue - applying shells 19 move away from each other synchronously, and the slide rods 21 drive the sealing plate 23 to translate through the transmission assembly 22, so that the state between the glue - applying box 15 and the second ball - feeding cylinder 17 is a communicating state.

[0046] In a case of this embodiment, an electric switch door is provided on the glue application box 15. When the glue application box 15 is opened, the opposite surfaces of the two glue application shells 19 can be supplemented with spherical glue; the glue application assembly further includes a converging plate 24. Two converging plates 24 are respectively fixed on both sides of the glue application shell 19, and the converging plates 24 are arranged obliquely. The included angle between the two converging plates 24 on the same side of the two glue application shells 19 is an acute angle. The transmission assembly 22 can be a displacement sensor cooperating with an electric cylinder. When the fourth driving source 20 drives the two sliding rods 21 to move away from each other, when the displacement sensor monitors that the displacement of the sliding rod 21 in the direction of moving away from each other reaches the threshold value, a signal is sent to the external controller, and the external controller controls the electric cylinder to drive the blocking plate 23 to slide so as to release the blocking of the second ball feeding cylinder 17, so that the glue application box 15 and the second ball feeding cylinder 17 are in a communicating state; of course, the transmission assembly 22 can also be a hydraulic cylinder, a cylinder, a gear cooperating with a rack and other structural components, or other mechanisms capable of realizing linear motion conduction, which will not be elaborated here.

[0047] In addition, the fourth driving source 20 can be a hydraulic cylinder, a cylinder and other components, or other mechanisms capable of realizing linear motion. This embodiment does not make specific limitations here. It should be noted that the power-consuming components such as the output source, the first driving source 203, the first power source, the second driving source 10, the second power source, the third power source, the fan, the third driving source 1802 and the fourth driving source 20 in this application are all connected to the external controller. The external controller is a prior art and this application does not improve it. Therefore, it is not necessary to disclose its specific mechanical structure and circuit structure, which does not affect the integrity of this application.

[0048] In actual application of this embodiment, in the initial state, the distance between the two glue application shells 19 is in the maximum state; the clean handball falling into the glue application box 15 rolls along its bottom surface to the blocking plate 23. Subsequently, when the fourth driving source 20 drives the two sliding rods 21 to move towards each other until the two glue application shells 19 are spliced, the two glue application shells 19 clamp the handball on the blocking plate 23 and apply glue to the surface of the handball. Subsequently, the fourth driving source 20 drives the two sliding rods 21 to move away from each other, then the two glue application shells 19 move away from each other synchronously, and the sliding rod 21 drives the blocking plate 23 to translate through the transmission assembly 22 so that the glue application box 15 and the second ball feeding cylinder 17 are in a communicating state. Then, while the glue application shell 19 slides away from the handball, the handball can enter the second ball feeding cylinder 17 and finally reach the feeding port of the launching assembly 2 for launching. The setting of the converging plate 24 can guide the handballs that have not rolled onto the blocking plate 23 between the two converging plates 24. The cross-section of the bottom of the glue application box 15 is conical, so that the handballs can roll along the bottom plate of the glue application box 15 after being guided and finally roll onto the blocking plate 23.

[0049] Working principle of the present invention: In the above embodiments of the present invention, a multi-functional handball launcher is provided. The ball feeding assembly 18 enables the handballs in the collecting hopper 14 to be intermittently conveyed to the degumming box 4. After the handballs enter the degumming box 4, the degumming assembly removes the glue from them, and after degumming, the handballs are pushed into the storage box 3 for storage. Subsequently, the ball feeding assembly 18 in the collecting hopper 14 conveys another handball to the degumming box 4 again, and the above process is repeated. Finally, the storage box 3 stores multiple clean handballs after degumming for training use. When starting handball training, the ball feeding assembly 18 in the first ball feeding cylinder 16 enables the storage box 3 to intermittently convey clean handballs to the glue coating box 15. The handballs entering the glue coating box 15 are coated with glue by the glue coating assembly, and after the glue coating is completed, they enter the second ball feeding cylinder 17. Multiple handballs coated with glue are arranged in the second ball feeding cylinder 17, and the lowermost handball is located at the feeding port of the launching assembly 2. After the launching assembly 2 launches the handball, the adjacent handball above it enters the feeding port of the launching assembly 2 and waits to be launched. This process is repeated to achieve the launching during handball training. It can also automatically remove the glue on the surface of the recycled handballs when the handballs are recycled, and automatically coat the glue before launching, avoiding manual glue coating and degumming by athletes, and improving the convenience of using the launcher.

[0050] The above has described in detail an embodiment of the present invention, but the content described is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
