Technical Field

[0001] The utility model relates to the technical field of felt-wrapping machines, in particular to an automatic felt-wrapping machine for tennis balls. Background Art

[0002] Tennis has been widely developed all over the world and has become a global sport. The outer layer of a tennis ball is a layer of soft material wrapped on the inner liner of a tennis ball, which is made of two symmetrical pieces of tennis felt. The traditional production method is to cut the felt as required and then wrap it manually, which has low work efficiency and large manual errors. The defective rate of the produced tennis balls is high. In order to improve the stability of the felt during transfer and to perform precise felt wrapping, thereby improving the yield of the product, the patent with announcement number CN105944341B proposes: an efficient and convenient fully automatic tennis ball felt wrapping machine, including a machine body, a felt separation device, a felt wrapping device and a conveying device. The felt separation device, the felt wrapping device and the conveying device are all arranged on the machine body. The separation device and the felt wrapping device are arranged on both sides of the conveying device. The felt separation device includes a feeding box and a separation mechanism. The cut and formed tennis ball felt is loaded in the feeding box; the separation mechanism includes a separation needle and a power mechanism 1. The separation needle is arranged at one end of the feeding box. The separation needle moves under the action of the power mechanism 1 to separate the outermost layer of tennis ball felt in the feeding box; the tennis ball inner liner coated with glue on the outer layer is placed on the conveying device, and the conveying device conveys the tennis ball inner liner to the felt separation device and the felt wrapping device in turn for operation. However, it cannot quickly transport and position the inner ball when in use, and the transportation and pasting of the felt cannot be formed in one time, which leads to its low efficiency. For this reason, the present application proposes an automatic tennis ball felt wrapping machine. Utility Model Content

[0021] See also Figure 1-Figure 6The utility model provides a technical solution: an automatic felting machine for tennis balls, comprising a frame 1, a table top 2, a first cylinder 4, a felt feeding assembly 10 and a felting assembly 14. The top of the frame 1 is fixedly connected to the table top 2, the top of the table top 2 is fixedly connected to the stand 3, the top of the table top 2 and the outside of the stand 3 are fixedly connected to a plurality of first cylinders 4. In this embodiment, four first cylinders 4 are provided, and each telescopic end of the first cylinder 4 is fixedly connected to a thimble 5. The four thimbles 5 are combined into a holding structure for holding the inner ball body in a predetermined position. By means of the four first cylinders 4 arranged on the table top 2 and the stand 3 and the thimble 5, the inner ball sent by the push plate 8 can be clamped and positioned quickly and accurately, which can improve the stability of subsequent felting. The top of the table top 2 is fixedly connected to a guardrail 15, and the guardrail 15 is located on the outside of the stand 3, which can be In order to protect the equipment during felting and reduce the occurrence of accidents, a mounting frame 6 is fixedly connected to one side of the table 2, and a reciprocating linear conveying module 7 is arranged on the top of the mounting frame 6. In the present embodiment, the reciprocating linear conveying module 7 is a sliding rod type linear module, and a pushing plate 8 is fixedly connected to one side of the reciprocating linear conveying module 7. By driving the pushing plate 8 to move on the mounting frame 6 by the reciprocating linear conveying module 7, the inner ball can be automatically fed, thereby improving the accuracy and efficiency of feeding. A lower hopper 9 is fixedly connected to the top of the table 2 to facilitate the conveying of the tennis balls formed after felting for subsequent processing. Two felt wrapping assemblies 14 for wrapping the felt on the inner ball body are arranged on the top of the table 2 and on both sides of the vertical frame 3, and two felt feeding assemblies 10 for supplying felt to the felt wrapping assemblies 14 are arranged on the outside of the frame 1.

[0022] Furthermore, the felt wrapping assembly 14 includes a machine base 141, which is fixed on the top of the table 2. A cylinder linear module 142 is arranged on the top of the machine base 141. A receiving plate 143 is fixedly connected to the top of the cylinder linear module 142. A servo motor 144 is fixedly connected to one side of the receiving plate 143. The output shaft of the servo motor 144 passes through the receiving plate 143 and is fixedly connected to a main frame 145. The cylinder linear module 142 is moved horizontally on the machine base 141 to meet the needs of taking felt materials and contacting and wrapping with the inner ball. The main frame 145 is driven to rotate by the servo motor 144 to facilitate the felt to be wrapped. The second vacuum suction cup 147 at its front end can absorb the felt and can also change direction to contact the inner ball when wrapping the felt. The main frame 145 is fixedly connected to the end close to the vertical frame 3 with a top plate 146. The two sides of the top plate 146 are symmetrically and rotatably connected to two second vacuum suction cups 147. The two sides of the main frame 145 are symmetrically and rotatably connected to two third cylinders 148. The telescopic ends of the two third cylinders 148 are rotatably connected to the corresponding second vacuum suction cups 147. The second vacuum suction cups 147 can be driven to rotate by the third cylinder 148, so as to fit the inner ball and ensure that the felt can be completely attached to the outer wall of the inner ball.

[0023] Furthermore, the felt feeding assembly 10 includes a fixed frame 101, which is fixed on the top of the table 2. A synchronous belt linear module 102 is arranged on one side of the fixed frame 101. A second cylinder 103 is fixedly connected to the side of the synchronous belt linear module 102 away from the fixed frame 101. A first vacuum suction cup 104 is fixedly connected to the bottom end of the second cylinder 103. A placing table 105 used in conjunction with the first vacuum suction cup 104 is arranged at the bottom of the fixed frame 101. The synchronous belt linear module 102 can drive the second cylinder 103 and the first vacuum suction cup 104 to move back and forth in a linear manner, and with the cooperation of the second cylinder 103 and the first vacuum suction cup 104, the felt can be adsorbed and fed.

[0024] Furthermore, two axial cylinders 11 are symmetrically fixedly connected to the bottom of the table 2, and the telescopic ends of the axial cylinders 11 are fixedly connected to the lifting cylinders 12. The top of the lifting cylinders 12 passes through the table 2 and is fixedly connected to the transfer platform 13. The axial cylinders 11 drive the lifting cylinders 12 and the transfer platform 13 to move horizontally, so that the felt on the first vacuum suction cup 104 can be easily picked up, and can also be moved to the material picking position of the second vacuum suction cup 147. The lifting cylinders 12 can drive the transfer platform 13 to move upward, and then the felt can be sent to the second vacuum suction cup 147 for easy feeding.

[0025] In summary: first, the inner ball is placed on the front end of the push plate 8. At this time, the reciprocating linear conveying module 7 drives the push plate 8 to slide on the mounting frame 6. When the inner ball moves between the four ejector pins 5, the four first cylinders 4 drive the ejector pins 5 to extend forward, and then the inner ball is squeezed and fixed by the four ejector pins 5. Then, the reciprocating linear conveying module 7 drives the push plate 8 to reset. During this process, the second cylinder 103 drives the first vacuum suction cup 104 to move down to absorb the felt on the material table 105. Then, the synchronous belt linear module 102 drives the second cylinder 103 and the first vacuum suction cup 104 to move downward to absorb the felt on the material table 105. A vacuum suction cup 104 moves horizontally on the fixed frame 101. When the first vacuum suction cup 104 moves to the top of the transfer platform 13, the first vacuum suction cup 104 puts the felt on the top of the transfer platform 13, and drives the lifting cylinder 12 and the transfer platform 13 to move toward the vertical frame 3 through the axial cylinder 11. The receiving plate 143 is driven to move on the machine base 141 through the cylinder linear module 142. Then the servo motor 144 drives the main frame 145 to rotate downward, so that the top plate 146 and the second vacuum suction cup 147 are placed on the top of the transfer platform 13. 12 drives the transfer platform 13 to move up, so that the felt on the top of the transfer platform 13 contacts the top plate 146 and the second vacuum suction cup 147, and the felt is adsorbed by the two second vacuum suction cups 147. After the adsorption is completed, the lifting cylinder 12 drives the transfer platform 13 to move down and reset, and the servo motor 144 drives the main frame 145 to rotate again, so that the main frame 145 is parallel to the table 2. After the second vacuum suction cups 147 on the felt-wrapping components 14 on both sides adsorb the felt, the main frame 145 is driven again by the cylinder linear module 142 to approach the inner ball, and the two top plates 146 and the inner ball are contacted. After the contact, the first cylinder 4 drives the ejector pin 5 to separate from the inner ball, and drives the second vacuum suction cup 147 to rotate through the third cylinder 148, so that the four second vacuum suction cups 147 are in contact with the inner ball. At this time, the felt can be adhered to the outside of the inner ball, and the two main frames 145 have different angles, so that the two groups of second vacuum suction cups 147 can be staggered alternately to ensure the integrity of the felt coating. After the tennis ball is felted, the cylinder linear module 142 drives the receiving plate 143 and the main frame 145 to separate from the inner ball. At this time, the tennis ball can fall into the discharge hopper 9 for automatic unloading.
