[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0023] Reference Figure 1-4 A fixed-length cutting device for processing the ball conveying pipe of a table tennis ball serving machine includes a workbench 1 and a limiting mechanism and a cutting mechanism installed on the workbench 1. The limiting mechanism includes a support 2, a limiting part 8, an adjusting seat 9, a cylinder 10, a fixed-length component 11, a limiting bolt 12, and a baffle 13. The support 2 is installed in a groove in the middle of the workbench 1. The adjusting seats 9 are in two sets, which are installed opposite each other at both ends near the workbench 1. The limiting parts 8 are in pairs and slide on the upper end of the adjusting seats 9 respectively. The cylinder 10 is installed in the middle of the adjusting seat 9, and its output end is fixedly connected to the bottom surface of the workbench 1. The fixed-length component 11 is slidably installed at one end of the workbench 1 and can be limited by the limiting bolt 12. The baffle 13 slides along the sliding groove 1101 in the middle plate of the fixed-length component 11.

[0024] According to the length of the ball conveying pipe cut, stretch the fixed length component 11 at one end of the workbench 1 to move the fixed length component 11 to the predetermined position. Then, rotate the limit bolt 12 to limit the movement of the fixed length component 11 and slide the baffle 13 along the slide groove 1101 to move the baffle 13 to the middle position of the fixed length component 11.

[0025] Drive cylinder 10, which drives adjusting seat 9 to move upward, so that limiting part 8 moves out of worktable 1. Then, the limiting parts 8 on both sides of adjusting seat 9 can be pushed to open the distance between the two limiting parts 8, so that the ball conveying pipe can be placed on support 2 from above the middle of worktable 1, and one end of the ball conveying pipe can be abutted against baffle 13. Then, push the two limiting parts 8 towards the middle of worktable 1 so that the two limiting parts 8 fit together and the contact part of the two limiting parts 8 is in the middle of worktable 1.

[0026] Drive the cylinder 10 to extend the output end of the cylinder 10, which in turn drives the adjusting seat 9 to move downward, and the limiting part 8 moves downward simultaneously until the limiting part 8 fits against the ball conveying pipe, thereby applying pressure to limit the ball conveying pipe.

[0027] The drive motor 3 drives the movable seat 6 to move along the slide rail 4 via the lead screw 5. The movable seat 6 can then drive the cutting machine 7 to move downwards. Once the cutting machine 7 is started, it can cut the ball conveying pipe.

[0028] After cutting, the drive cylinder 10 drives the adjusting seat 9 to move upward, so that the limiting part 8 loses pressure on the ball conveying pipe. Move the baffle 13 to one side of the slide 1101, and the cut ball conveying pipe can be removed. Then move the baffle 13 back to the middle of the fixed length part 11, and push the subsequent ball conveying pipe to continue to abut against the baffle 13. The drive cylinder 10 can then apply pressure to the ball conveying pipe through the limiting part 8.

[0029] This device allows for easy placement of ball delivery pipes of different sizes, and can be inserted directly from above the fixing device, unlike conventional devices which require insertion from one side and pushing to complete the placement. The entire placement process is time-saving and labor-saving, and the ball delivery pipes can be easily removed after cutting.

[0030] The cutting mechanism includes a motor 3, a slide rail 4, a lead screw 5, a movable seat 6, and a cutting machine 7. The motor 3 is mounted on the worktable 1 via a mounting bracket. The lead screw 5 is mounted at the output end of the motor 3. The movable seat 6 is connected to the lead screw 5 and slides along the slide rail 4 mounted on the mounting bracket. The cutting machine 7 is fixed on the movable seat 6.

[0031] The cutting mechanism can move up and down. After cutting, the cutting machine 7 is moved upward so that the ball conveying pipe can be placed directly above the worktable 1 and quickly positioned.

[0032] The worktable 1 is located below the cutting blade of the cutting machine 7 and is also provided with a discharge port 101. When cutting the ball conveying pipe, there will be debris. The discharge port 101 is located below the cutting blade of the cutting machine 7 so that the debris can fall from the discharge port 101 and it is also convenient to clean the debris in the middle of the worktable 1 later.

[0033] Two limiting parts 8 located on the same set of adjusting seats 9 are set on the same horizontal plane, and one of the limiting parts 8 is equipped with a fixed shaft at one end, and the other limiting part 8 is provided with a slot at one end. When the two limiting parts 8 are in contact, the fixed shaft can be inserted into the slot. The bottom edge of the two limiting parts 8 in the same set that are in contact is provided with an arc-shaped groove. When the two limiting parts 8 are in contact, the stability between the two limiting parts 8 can be increased by inserting the fixed shaft at the end of one limiting part 8 into the slot at the end of the other limiting part 8, and the arc-shaped grooves at the bottom edge of the two limiting parts 8 can fit together to jointly limit the ball conveying pipeline.

[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
