Description

Technical Field

[0001] This utility model relates to the technical field of steel ball machines, and in particular to a feed / discharge reversing device for steel ball machines. Background Technology

[0002] A steel ball machine is a device used to process steel ball blanks into round shapes. This type of equipment is usually equipped with upper and lower grinding discs. The surface of the lower grinding disc is provided with annular grooves. After the steel ball blank falls into the annular grooves, the upper and lower grinding discs begin to rotate relative to each other. The steel ball blank rolls along the annular grooves and is ground at the same time. After a period of processing, a relatively regular steel ball is obtained.

[0003] A baffle-type reversing device is typically installed between the inlet and outlet of a steel ball mill. A circular track is installed outside the inlet and outlet, allowing the steel balls to roll and grind once inside the mill before flowing out of the inlet and then rotating along the circular track to the other side of the reversing device for further processing. This allows for the reversal of the steel ball's flow direction. During this process, the degree of grinding of the steel balls can be observed at any time.

[0004] Existing commutators are generally set as a straight plate, simply dividing the two sides of the feed inlet; therefore, when the steel balls are discharged, they tend to accumulate in large quantities at the junction of the circular track and the feed inlet, thus affecting the overall working efficiency of the steel ball machine.

[0005] Therefore, a device is needed to prevent steel balls from accumulating at the feed inlet. Utility Model Content

[0006] The purpose of this invention is to solve the above-mentioned problems and provide a feed / discharge reversing device for a steel ball machine.

[0007] The technical solution of this utility model is: a feed and discharge reversing device for a steel ball machine. The steel ball machine includes a lower grinding disc, an upper pressure disc, and an annular track. The annular track includes a bottom plate and inner and outer outer plates. A fan-shaped material inlet is opened on the edge of the upper pressure disc. The material inlet is connected to the annular track. A vertical material inlet baffle is provided on the outer side of the material inlet. The bottom plate of the annular track is higher than the top surface of the lower grinding disc. The commutator includes a feed inlet separator and a track baffle. The feed inlet separator is vertically installed in the middle of the fan-shaped feed inlet, dividing the feed inlet into an outlet and an inlet. The track baffle is installed in the annular track and connects with the feed inlet separator. The feed inlet separator separates the feed inlets, and the track baffle separates the annular track, which enables the steel balls to run through the track, allowing more steel balls to be added into the annular track, enabling the steel ball machine to work continuously and achieve higher production efficiency.

[0008] The feed inlet separator includes a square stop and a guide plate; the guide plate is fixed to the bottom of the square stop and extends to one side of the discharge port; the bottom surface of the guide plate is in contact with the top surface of the lower grinding disc; the edge of the extension of the guide plate is provided with a slope; when the steel ball rotates to the discharge port, with the intervention of the guide plate, the steel ball will fall from the guide plate into the circular track, so as to realize the smooth reversal of the steel ball and avoid the steel ball from accumulating at the discharge port, which would affect the working efficiency of the steel ball machine.

[0009] The track baffle includes a discharge slide and a feed slide arranged opposite each other; one end of the discharge slide and the feed slide respectively mates with the corresponding side of the square stop block; the other end of the discharge slide and the feed slide respectively abuts against the annular track. The track baffle separates the annular track and provides guidance for the steel ball, allowing the steel ball to rotate only in one direction along the annular track.

[0010] Preferably, the material outlet partition block further includes a discharge guide plate and a feed guide plate; the discharge guide plate is located on one side of the discharge outlet, and the feed guide plate is located on one side of the feed inlet; The discharge guide plate includes tangent arc-shaped plate armor and straight plate armor. The straight plate armor is fixed to one side of the square stop block located at the discharge port, and the arc-shaped plate armor is correspondingly abutted against the inner end of the discharge port. The feed guide includes a tangent arc-shaped plate B and a straight plate B. The straight plate B is fixed to one side of the square stop located at the feed inlet, and the arc-shaped plate B is correspondingly abutted against the inner end of the feed inlet. The discharge guide and the feed guide can guide the steel balls and prevent them from falling into corners and failing to flow out.

[0011] Preferably, both the discharge and feed slides are arc-shaped, with one side of each slide tangent to the corresponding side of the square stop; the other side of each slide is tangent to the inner side of the outer side plate of the annular track. The arc shape and tangency of the discharge and feed slides to the annular track prevent the formation of dead angles in the steel ball's flow path, ensuring normal steel ball flow and preventing accumulation.

[0012] Preferably, the track baffle further includes a cover plate, which is disposed on top of the discharge slide plate and the feed slide plate, with the edge of the cover plate pressing against the top of the outer side plate of the annular track. The cover plate can limit the track baffle to a certain extent, preventing the track baffle from shifting under the impact of the steel ball.

[0013] Furthermore, a fixing angle iron is provided on the side of the cover plate; a fixing seat is provided at the bottom of the inner side plate of the annular track, and a horizontal connecting rod is provided on the fixing seat, with the end of the horizontal connecting rod corresponding to the fixing seat; a connecting screw is provided between the horizontal connecting rod and the fixing seat. This allows the track baffle to be completely fixed in place.

[0014] Preferably, the inner side plate of the annular track has a notch corresponding to the feed inlet. The feed inlet baffle connects to both sides of the notch to prevent the steel ball from falling out of the gap between the lower grinding disc and the annular track when it enters the track. A wedge block is provided at the bottom of the notch, with the top of the wedge block aligned with the top surface of the bottom plate of the annular track and the bottom of the wedge block lower than the top surface of the guide plate. The wedge block not only helps the steel ball enter the annular track smoothly but also prevents it from falling out of the gap.

[0015] Preferably, a vertical end plate is provided on the outer side of the feed inlet, and a vertical square groove is provided on the end plate; a sliding platform is provided at the end of the square stop block, and the sliding platform is slidably disposed within the square groove. This facilitates the positioning of the feed inlet separator block during installation.

[0016] Furthermore, a protruding tenon is provided in the center of the square groove, and a vertical mortise is provided in the center of the slide table, with the shapes of the tenon and the mortise corresponding. The tenon and the mortise fit together to limit the square stop block, preventing the material outlet separator block from deflecting and affecting normal use.

[0017] Preferably, the square stop block has ring-shaped handles on both sides, facilitating the installation and removal of the feed inlet separator.

[0018] The beneficial effects of this utility model are as follows: The feed and discharge reversing device for the steel ball machine of this utility model has the following advantages: 1. The bottom of the material outlet separator block of this utility model is provided with a guide plate with an inclined surface. The steel ball can fall into the annular track along the inclined surface of the guide plate at the outlet, thereby avoiding the accumulation of steel balls at the outlet.

[0019] 2. The commutator of this utility model includes a feed inlet separator and a track baffle, which forms a continuous and orderly track around the lower grinding disc, making it easy to observe the regularity of the steel balls at any time. Attached Figure Description

[0023] Example 1: See Figure 1-5 A reversing device for feeding and discharging steel ball machines is disclosed. The steel ball machine includes a lower grinding disc 02, an upper pressure disc 01, and an annular track 04. The annular track 04 includes a base plate and inner and outer side plates 043. The upper pressure disc 01 has a fan-shaped feed inlet 012 on its edge, which is connected to the annular track 04. A vertical feed inlet baffle 0122 is provided on the outer side of the feed inlet 012. The base plate of the annular track 04 is higher than the top surface of the lower grinding disc 02. Vertical sliding rods are provided on both sides of the upper pressure plate 01, and a guide sleeve 011 is provided on the top of the upper pressure plate 01, which is sleeved on the outside of the sliding rods. A hydraulic mechanism 031 is provided on the top of the sliding rods, and the movable end of the hydraulic mechanism 031 is fixed to the top of the upper pressure plate 01. It is used to adjust the distance between the upper pressure plate 01 and the lower grinding plate 02, thereby adjusting the diameter of the steel ball after grinding; it can also adjust the downward pressure applied by the upper pressure plate 01 to the steel ball.

[0024] The commutator includes a feed inlet separator 1 and a track baffle 2. The feed inlet separator 1 is vertically installed in the middle of the fan-shaped feed inlet 012, dividing the feed inlet 012 into a discharge port 012 and a feed port 012. The track baffle 2 is installed in the annular track 04 and is connected to the feed inlet separator 1. The feed inlet separator 1 separates the feed inlet 012, and the track baffle 2 separates the annular track 04, which can connect the running path of the steel balls, thereby allowing more steel balls to be added into the annular track 04, enabling the steel ball machine to work continuously and have higher production efficiency.

[0025] The feed inlet separator 1 includes a square stop block 11 and a guide plate 12. The guide plate 12 is fixed to the bottom of the square stop block 11 and extends to one side of the discharge port 012. The bottom surface of the guide plate 12 is in contact with the top surface of the lower grinding disc 02. An inclined surface 121 is provided on the edge of the extension of the guide plate 12. When the steel ball moves to the discharge port 012, with the intervention of the guide plate 12, the steel ball will fall from the guide plate 12 into the annular track 04 to realize the smooth reversal of the steel ball and avoid the steel ball from accumulating at the discharge port 012, which would affect the working efficiency of the steel ball machine.

[0026] The track baffle 2 includes a discharge slide plate 21 and a feed slide plate 22 arranged opposite to each other; one end of the discharge slide plate 21 and the feed slide plate 22 respectively engages with the corresponding side of the square stop block 11; the other end of the discharge slide plate 21 and the feed slide plate 22 respectively abuts against the annular track 04. The track baffle 2 separates the annular track 04, providing guidance for the steel ball, so that the steel ball can only rotate in one direction along the annular track 04.

[0027] The material outlet separator 1 also includes a discharge guide plate 13 and a feed guide plate 14; the discharge guide plate 13 is located on one side of the discharge outlet 012, and the feed guide plate 14 is located on one side of the feed outlet 012. The discharge guide plate 13 includes a tangent arc-shaped plate and a straight plate. The straight plate is fixed to one side of the square stop 11 located at the discharge port 012, and the arc-shaped plate is correspondingly abutted against the inner end of the discharge port 012. The feed guide plate 14 includes a tangent arc-shaped plate B and a straight plate B. The straight plate B is fixed to one side of the square stop block 11 located at the feed inlet 012, and the arc-shaped plate B is correspondingly abutted against the inner end of the feed inlet 012. The discharge guide plate 13 and the feed guide plate 14 can provide guidance for the steel balls and prevent the steel balls from falling into corners and being unable to flow out.

[0028] Both the discharge slide plate 21 and the feed slide plate 22 are arc-shaped. One side of each slide plate 21 and the feed slide plate 22 is tangent to the corresponding side of the square stop block 11. The other side of each slide plate 21 and the feed slide plate 22 is tangent to the inner side of the outer side plate 043 of the annular track 04. The arc shape of both the discharge slide plate 21 and the feed slide plate 22 and their tangency to the annular track 04 can prevent dead corners from forming on the flow path of the steel balls, thereby ensuring the normal flow of the steel balls and preventing accumulation.

[0029] The track baffle 2 also includes a cover plate 23, which is disposed on top of the discharge slide plate 21 and the feed slide plate 22. The edge of the cover plate 23 presses against the top of the outer side plate 043 of the annular track 04. The cover plate 23 can limit the track baffle 2 to a certain extent, preventing the track baffle 2 from shifting under the impact of the steel ball.

[0030] A fixing angle iron 24 is provided on the side of the cover plate 23; a fixing seat is provided at the bottom of the inner side plate 042 of the annular track 04, and a horizontal connecting rod 0422 is provided on the fixing seat, with the end of the horizontal connecting rod 0422 corresponding to the fixing seat; a connecting screw 4 is provided between the horizontal connecting rod 0422 and the fixing seat. This can completely fix the track baffle 2 in place.

[0031] The inner side plate 042 of the annular track 04 is provided with a notch 0421 corresponding to the feed inlet 012. The feed inlet baffle 0122 is connected to both sides of the notch 0421 to prevent the steel ball from falling out of the gap between the lower grinding disc 02 and the annular track 04 when it enters the annular track 04. A wedge block 3 is provided at the bottom of the notch 0421. The top of the wedge block 3 is aligned with the top surface of the bottom plate of the annular track 04, and the bottom of the wedge block 3 is lower than the top surface of the guide plate 12. The wedge block 3 not only helps the steel ball to enter the annular track 04 smoothly, but also prevents the steel ball from falling out of the gap.

[0032] A vertical end plate 0121 is provided on the outer side of the feed inlet 012, and a vertical square groove 01211 is provided on the end plate 0121; a sliding table 16 is provided at the end of the square stop block 11, and the sliding table 16 is slidably disposed in the square groove 01211. This facilitates the positioning of the feed inlet separator 1 during installation.

[0033] A protruding tenon 01212 is provided in the middle of the square slide groove 01211, and a vertical mortise 161 is provided in the middle of the slide table 16. The shape of the tenon 01212 corresponds to that of the mortise 161. The tenon 01212 and the mortise 161 cooperate to limit the square stop block 11 and prevent the material outlet separator block 1 from deflecting, which would affect normal use.

[0034] Both sides of the square stop block 11 are provided with ring-shaped handles 15, which facilitates the installation and removal of the feed inlet separator block 1.

[0035] The working principle of this embodiment: The feed / discharge reversing device physically separates the feed inlet 012 of the steel ball mill and guides the flow of steel balls, thereby enabling the processing of a large number of steel balls at once. In this embodiment, the feed inlet separating block 1 is equipped with a guide plate 12 at the bottom, which scoops up the steel balls on the lower grinding disc 02 and guides them into the annular track 04. After passing through the annular track 04, the steel balls flow into the feed inlet 012, allowing them to be further ground inside the steel ball mill.

[0036] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The differences are: The lower grinding disc 02 has several annular grooves 021 arranged adjacently from the edge inwards, and the width of the guide plate 12 is greater than the overall width of the annular grooves 021. The guide plate 12 can guide all the steel balls entering the discharge port 012, thereby preventing the steel balls from accumulating at the discharge port 012.
