Description

Technical Field

[0001] This utility model relates to the technical field of vertical steel ball machine accessories, and in particular to a steel ball inlet inner support device for a vertical steel ball machine. Background Technology

[0002] Existing vertical steel ball machines have dedicated feeding and discharging mechanisms. For example, patent CN212020427U discloses a feeding and discharging mechanism for a ball machine, which includes an outer turntable, an M-shaped dividing baffle, and a flow divider. An inner protective ring is provided on the inner edge of the outer turntable. The outer turntable feeds material by rotating around the inner protective ring. An upper grinding disc is located inside the inner protective ring. A notch is opened on the upper grinding disc. The M-shaped dividing baffle is fixedly connected to the top of the notch on the upper grinding disc. The M-shaped dividing baffle and the notch on the upper grinding disc form the feeding and discharging channels. The opening at the lower end of the M-shaped dividing baffle is the same size as the notch on the upper grinding disc. The M-shaped dividing baffle and the notch on the upper grinding disc form the feeding and discharging channels. An opening on the inner protective ring corresponds to the notch on the upper grinding disc, and a flow divider is fixedly connected to the middle of the opening. The outer turntable also has an outer protective ring on its outer edge. There is a gap between the outer wall of the diverter plate and the inner wall of the outer protective ring. In actual operation, the steel ball blanks that are about to enter the feeding channel at the inlet can easily be squeezed into the gap and no longer participate in the steel ball circulation of the steel ball machine. Utility Model Content

[0003] The purpose of this utility model is to solve the above problems and provide a vertical steel ball machine steel ball inlet inner support device.

[0004] The technical solution of this utility model is as follows: A steel ball inlet support device for a vertical steel ball machine is installed above the outer turntable at the inlet of the steel ball machine; an inner protective ring is provided on the inner edge of the outer turntable, and an outer protective ring is provided on the outer edge; the inner and outer protective rings clamp the outer turntable in the middle and guide the steel balls on the outer turntable; the outer turntable is provided with a flow divider plate; the two sides of the flow divider plate are the inlet and the outlet, respectively; the support device includes an outer screw, an inner screw, and an adjusting pipe; the outer end of the outer screw abuts against the inner wall of the flow divider plate, and the inner end is screwed against the outer end of the adjusting pipe. The inner screw is threaded to the inner end of the regulating tube, and the outer end is connected to the inner protective ring. The regulating tube has a cavity in the middle. The inner diameter of the cavity is greater than the inner diameter of the end of the regulating tube. The threads of the outer screw and the inner screw are opposite. Rotating the regulating tube causes the outer screw and the inner screw to extend and retract synchronously relative to the regulating tube. By controlling the extension of the outer screw and the inner screw relative to the regulating tube, the flow divider plate is pressed against the inner wall of the outer protective ring, reducing the gap size between the outer wall of the flow divider plate and the inner wall of the outer protective ring, and reducing the possibility of the steel ball blank entering the gap.

[0005] Preferably, the outer end of the outer screw abuts against the tip of the manifold to create a squeezing effect on the manifold.

[0006] Preferably, the outer wall of the regulating tube is square to facilitate rotation of the regulating tube.

[0007] Preferably, the outer end of the outer screw abuts against the lower middle part of the vertical direction of the flow divider plate, ensuring that the lower end of the flow divider plate abuts against the inner wall of the outer protective ring as much as possible, so as to prevent the steel ball blank from entering the gap.

[0008] Preferably, the steel ball inlet inner support device of the vertical steel ball machine is arranged radially along the outer turntable. On the one hand, this minimizes the outward extension length of the outer screw and inner screw relative to the adjusting pipe, and on the other hand, it ensures that the outer screw and the diverter pipe are stably abutted, and the inner screw and the inner protective ring are stably abutted.

[0009] Preferably, the outer end face of the outer screw is an arc-shaped surface that matches the flow divider plate, thereby improving the stability of the outer end of the outer screw against the flow divider plate.

[0010] Preferably, the steel ball inlet inner support device of the vertical steel ball machine also includes an adjusting nut; the inner protective ring has a through hole; the inner screw passes through the through hole; the adjusting nut and the inner screw are threaded together and abut against the outer wall of the inner protective ring; when the adjustment amount of the adjusting tube is insufficient, the outer screw and the inner screw can be set to a longer length and adjusted using the adjusting nut to ensure that the inner screw is connected to the inner protective ring and the outer screw abuts against the outer protective ring.

[0011] Furthermore, the perforation is a vertically elongated hole, which allows adjustment of the vertical position where the inner screw connects to the inner retaining ring, thereby changing the vertical height of the entire inner support device. This change in the vertical height of the inner support device ensures that the gap between the lower end of the splitter plate and the inner wall of the outer retaining ring is minimized.

[0012] Furthermore, the perforation extends through the upper edge of the inner retaining ring to facilitate the on-site installation of the inner support device.

[0013] Furthermore, the steel ball inlet inner support device of the vertical steel ball machine also includes a limiting nut; the limiting nut is threaded with the inner screw and abuts against the inner wall of the inner protective ring; the limiting nut can ensure the connection stability between the inner screw and the inner protective ring.

[0014] Preferably, the external and internal screws have the same thread size to facilitate manufacturing.

[0015] The beneficial effects of this utility model are as follows: The vertical steel ball machine steel ball inlet inner support device of this utility model has the following advantages: (1) By controlling the outer screw and inner screw to extend outward relative to the adjusting tube, the flow divider plate is pressed against the inner wall of the outer protective ring, thereby reducing the gap size between the outer wall of the flow divider plate and the inner wall of the outer protective ring and reducing the possibility of the steel ball blank entering the gap. (2) The inner support device of this utility model is arranged radially along the outer turntable. On the one hand, it minimizes the extension length of the outer screw and inner screw relative to the adjusting tube, and on the other hand, it ensures that the outer screw and the diverter are stably abutted, and the inner screw and the inner protective ring are stably abutted.

[0017] Example 1: See Figure 1-5 A vertical steel ball machine's steel ball inlet internal support device is installed above the outer turntable 00 at the inlet of the steel ball machine; the inner edge of the outer turntable 00 is provided with an inner protective ring 01, and the outer edge is provided with an outer protective ring 02; the inner protective ring 01 and the outer protective ring 02 clamp the outer turntable in the middle and guide the steel balls on the outer turntable 00; the outer turntable 00 is provided with a flow divider plate 03; the two sides of the flow divider plate 03 are the inlet and the outlet, respectively; the internal support device includes an outer screw 1, an inner screw 2, and an adjusting pipe 3; the outer end of the outer screw 1 abuts against the inner wall of the flow divider plate 03, and the inner end is threadedly connected to the outer end of the adjusting pipe 3; the inner screw 1... The outer end of the screw 2 is threadedly connected to the inner end of the regulating tube 3, and the outer end is connected to the inner protective ring 01; the regulating tube 3 has a cavity 31 in the middle; the inner diameter of the cavity 31 is greater than the inner diameter of the end of the regulating tube 3; the threads of the outer screw 1 and the inner screw 2 are opposite; rotating the regulating tube 3 causes the outer screw 1 and the inner screw 2 to extend and retract synchronously relative to the regulating tube 3; by controlling the extension of the outer screw 1 and the inner screw 2 relative to the regulating tube 3, the diverter plate 03 is pressed against the inner wall of the outer protective ring 02, reducing the gap size between the outer wall of the diverter plate 03 and the inner wall of the outer protective ring 02, and reducing the possibility of the steel ball blank entering the gap.

[0018] Compared with the prior art, this utility model controls the outer screw 1 and the inner screw 2 to extend outward relative to the adjusting tube 3, so that the diverter plate 03 abuts against the inner wall of the outer protective ring 02, thereby reducing the gap size between the outer wall of the diverter plate 03 and the inner wall of the outer protective ring 02, and reducing the possibility of the steel ball blank entering the gap.

[0019] The outer end of the outer screw 1 abuts against the tip of the manifold 03 to create a squeezing effect on the manifold 03.

[0020] The outer wall of the regulating tube 3 is square to facilitate rotation of the regulating tube 3.

[0021] The outer end of the outer screw 1 abuts against the lower middle part of the vertical direction of the diverter plate 03, ensuring that the lower end of the diverter plate 03 abuts against the inner wall of the outer protective ring 02 as much as possible, so as to prevent the steel ball blank from entering the gap.

[0022] The steel ball inlet inner support device of the vertical steel ball machine is set radially along the outer turntable 00. On the one hand, it minimizes the outward extension length of the outer screw 1 and inner screw 2 relative to the adjusting pipe 3. On the other hand, it ensures that the outer screw 1 is stably abutted against the diversion pipe and the inner screw 2 is stably abutted against the inner protective ring 01.

[0023] The outer end face of the outer screw 1 is an arc-shaped surface 11 that matches the flow divider 03, which improves the stability of the outer end of the outer screw 1 against the flow divider 03.

[0024] The steel ball inlet inner support device of the vertical steel ball machine also includes an adjusting nut 4; the inner protective ring 01 is provided with a through hole 011; the inner screw 2 passes through the through hole 011; the adjusting nut 4 is threadedly engaged with the inner screw 2 and abuts against the outer wall of the inner protective ring 01; when the adjustment amount of the adjusting tube 3 is insufficient, the outer screw 1 and the inner screw 2 can be set to a longer length and adjusted using the adjusting nut 4 to ensure that the inner screw 2 is connected to the inner protective ring 01 and the outer screw 1 abuts against the outer protective ring 02.

[0025] The perforation 011 is a vertical elongated hole, which allows adjustment of the vertical position where the inner screw 2 connects to the inner retaining ring 01, thereby changing the vertical height of the entire inner support device. Changing the vertical height of the inner support device ensures that the gap between the lower end of the diverter plate 03 and the inner wall of the outer retaining ring 02 is minimized.

[0026] The perforation 011 extends through the upper edge of the inner protective ring 01 to facilitate the on-site installation of the inner support device.

[0027] The working principle of this embodiment is as follows: Rotating the adjusting tube 3 causes the outer screw 1 and inner screw 2 to extend and retract synchronously relative to the adjusting tube 3. By controlling the extension of the outer screw 1 and inner screw 2 relative to the adjusting tube 3, the flow divider 03 is pressed against the inner wall of the outer protective ring 02, reducing the gap size between the outer wall of the flow divider 03 and the inner wall of the outer protective ring 02, thus reducing the possibility of the steel ball blank entering the gap. The inner support device is arranged radially along the outer turntable 00, minimizing the extension length of the outer screw 1 and inner screw 2 relative to the adjusting tube 3, and ensuring stable contact between the outer screw 1 and the flow divider tube, and stable contact between the inner screw 2 and the inner protective ring 01.

[0028] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that the threads of the external screw 1 and the internal screw 2 are the same to facilitate manufacturing.

[0029] The steel ball inlet inner support device of the vertical steel ball machine also includes a limiting nut 5; the limiting nut 5 is threadedly engaged with the inner screw rod 2 and abuts against the inner wall of the inner protective ring 01; the limiting nut 5 can ensure the connection stability between the inner screw rod 2 and the inner protective ring 01.
