[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-6, including a spinning machine body 1, a spinning mechanism 8, which is installed on both sides of the spinning machine body 1, the bottom of the spinning mechanism 8 is a spinning wheel, the top is a rotating motor, and the spinning wheel is connected to the rotating motor through a rotating shaft; a transmission component 9 is installed on the side of the spinning mechanism 8, and the transmission component 9 is composed of two sets of telescopic rods with different telescopic directions, which is convenient for controlling the spinning wheel on the spinning mechanism 8 to move in different directions. The first baffle 10 is fixed to the spinning mechanism 8 through a support rod, and the first baffle 10 is an arc-shaped plate design; a guide plate 11 is movably installed at the bottom of the first baffle 10, and a rotating shaft is installed on one side surface of the first baffle 10, and the guide plate 11 is connected to the first baffle 10 through the rotating shaft; a first torsion spring 12 is installed between the first baffle 10 and the guide plate 11, and when the guide plate 11 rotates through the rotating shaft, the guide plate 11 is reset by the first torsion spring 12; a slide groove 13 is fixed on the surface of the first baffle 10; the second baffle 14 is connected to the first baffle 10 through a slider on the surface The slide groove 13 on the surface of the baffle plate 10 is installed and connected, the length of the second baffle plate 14 is greater than that of the first baffle plate 10, and the second baffle plate 14 is also installed with a guide plate 11 and a first torsion spring 12. The first baffle plate 10 is extended by the second baffle plate 14. The extension length of the second baffle plate 14 is adjusted according to the splash range of the waste chips, so that the first baffle plate 10, the second baffle plate 14 and the guide plate 11 block the splashing waste chips to prevent the waste chips from splashing to the outside of the spinning machine body 1; the unloading mechanism is installed on the side of the first baffle plate 10, and the end is fixed to the inner wall of the spinning machine body 1.The unloading mechanism includes a support rod 15, a connecting plate 16 and a second torsion spring 17, wherein one end of the support rod 15 is fixed to the inner wall of the spinning machine body 1, and the height of the support rod 15 is flush with the guide plate 11, and the end of the support rod 15 away from the spinning machine body 1 is movably installed with a connecting plate 16, and a second torsion spring 17 is installed at the inner angle between the support rod 15 and the connecting plate 16. When the first baffle plate 10 and the second baffle plate 14 intercept the flying waste chips, the waste chips fall downward by the weight force and thus fall on the guide plate 11. Since the guide plate 11 is inclined, part of the waste chips slides down with the inclined slope, and part accumulates on the surface of the guide plate 11. When the wheel hub completes spinning, the spinning mechanism 8 drives the first baffle plate 10 to move to both sides of the spinning machine body 1. When the first baffle plate 10 moves, the surface of the guide plate 11 is resisted by the connecting plate 16 and begins to flip upward. At the same time, the connecting plate 16 is pushed by the guide plate 11 to the spinning machine body When the connecting plate 16 and the guide plate 11 are rotated by a certain angle, the two groups of parts are dislocated from each other, so that the guide plate 11 is driven by the first torsion spring 12 to reset, and the connecting plate 16 is driven by the second torsion spring 17 to reset. When the spinning process is performed again, the spinning mechanism 8 drives the first baffle 10 to move toward the middle of the spinning machine body 1 again. When the first baffle 10 moves, the guide plate 11 collides with the connecting plate 16 again, and the guide plate 11 is intercepted by the connecting plate 16. During the movement of the spinning mechanism 8, the guide plate 11 gradually rotates downward, and the waste accumulated on the surface of the guide plate 11 gradually slides off as the guide plate 11 flips. When the connecting plate 16 is staggered with the guide plate 11, when the guide plate 11 returns to its original position, the first baffle 10 also vibrates, so that the waste adhered to the surface of the first baffle 10 is shaken off, thereby maintaining the cleanliness of the first baffle 10 and reducing the operation of manual cleaning.

[0032] A mold 2 is installed in the middle of the spinning machine body 1. Four groups of movable grooves 3 are opened on the surface of the mold 2. A movable rod 4 is installed inside the movable groove 3. A movable shaft is installed at the bottom of the movable rod 4. The movable shaft is connected to the mold 2. The movable rod 4 is in a "√" shape as a whole. When the wheel hub presses the short rod of the movable rod 4, the long rod of the movable rod 4 gradually becomes vertical as the short rod moves. When the short rod of the movable rod 4 is parallel to the bottom of the mold 2, the long rod of the movable rod 4 will tilt toward the outside of the mold 2 to support and fix the inside of the wheel hub. An installation groove 5 is opened on the outer ring of the bottom of the mold 2. A compression spring 6 is installed inside the installation groove 5, and the top of the compression spring 6 is located below the short rod of the movable rod 4. When the wheel hub is spun, the short rod of the movable rod 4 is pushed upward by the compression spring 6, so that the wheel hub is moved upward, which further facilitates the demolding of the wheel hub and the mold 2. A die pressing mechanism 7 is arranged above the mold 2, and a cylinder is installed at the position of the die pressing mechanism 7 on the top of the spinning machine body 1. The telescopic end of the cylinder is connected to a rotating motor, and the rotating end of the rotating motor is connected to the die pressing. The up and down movement of the die pressing mechanism 7 is controlled by the cylinder, and the die pressing mechanism 7 is driven to rotate by the rotating motor, so that when the die pressing is pressed on the top of the wheel hub, the wheel hub rotates together with the die pressing mechanism 7.

[0033] A waste box 18 is placed at the bottom of the spinning machine body 1, and waste chips are collected uniformly through the waste box 18.

[0034] Working principle: when spinning the wheel hub, the blank of the wheel hub is put on the outside of the mold 2, and the top of the wheel hub is pressed and fixed by the die pressing mechanism 7, and then the mold 2 and the die pressing mechanism 7 drive the wheel hub to rotate, and the spinning mechanism 8 is moved to the side of the wheel hub through the transmission assembly 9 to spin the wheel hub. During the spinning process, the waste chips polished by the spinning wheel are intercepted by the first baffle 10 and the second baffle 14 to prevent the waste chips from splashing out of the spinning machine body 1. The waste intercepted by the baffles falls through the guide plate 11 to the waste box 18 at the bottom for unified collection. The bottom of the wheel hub gradually presses the short rod of the movable rod 4 to the bottom of the mold 2. When the movable rod 4 moves, the compression spring 6 is also pressed to the bottom of the mold 2. When the wheel hub is spun After completion, the die pressing mechanism 7 is lifted upward, and the pressure of the compression spring 6 is reduced, thereby pushing the movable rod 4 to rotate upward. When the movable rod 4 rotates, it pushes the wheel hub upward to facilitate the subsequent demolding of the wheel hub from the mold 2. When the spinning mechanism 8 drives the spinning wheel to move to both sides, the first baffle 10 and the second baffle 14 also move to both sides. During the movement, the guide plate 11 at the bottom of the first baffle 10 will flip over due to the push of the connecting plate 16. When the guide plate 11 approaches the mold 2 again, the connecting plate 16 also contacts the guide plate 11 again, flipping the guide plate 11 downward, so that the waste accumulated on the surface of the guide plate 11 falls downward, thereby achieving the purpose of self-cleaning and reducing the frequency of staff cleaning the baffle.
