DETAILED DESCRIPTION

[0024] The utility model discloses below will combine the drawings in the embodiment of the utility model, and the specific working principle will be introduced. Figures 1-5 The technical solutions in the embodiments of the utility model are clearly and completely described, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] The utility model provides a technical scheme: a bearing ring blanking mechanism, including the lifting conveyor 1, the right upper end fixed support frame 2 of lifting conveyor 1, support frame 2 is fixed with support plate 3 on, be equipped with lifting structure 4 on support plate 3, the lower end fixed with the baffle 5 of left low right height of lifting structure 4, the right lower end fixed with the guide plate 6 of lifting conveyor 1, the lower portion of guide plate 6 is equipped with the material frame 7, when working, after the bearing ring of the roll type mesh belt furnace heat treatment is conveyed to lifting conveyor 1, wherein lifting conveyor 1 is linked with the roll type mesh belt furnace, wherein the bearing ring on lifting conveyor 1 is lifted right upper end and will drop down to guide plate 6, wherein guide plate 6 is set as left high right low inclination, the bearing ring on guide plate 6 will slide to the baffle 5 in its front, then reenter the material frame 7, when blanking a period of time, lifting structure 4 will start and lift baffle 5 a distance upwards, like this in the process of blanking lifting structure 4 will be lifted a distance upwards at certain time, until the material frame 7 is filled with material. In order to prevent the bearing ring on guide plate 6 from falling from the front and rear edges of guide plate 6, side baffles can be fixed on the front and rear edges of guide plate 6. To facilitate the movement and fixation of the material frame 7, universal wheels can be provided at the four corners of the bottom surface of the material frame 7, and brake pads are provided on the universal wheels. The utility model lifts the bearing ring by the setting of lifting conveyor 1 to a height, so that a material frame 7 with a higher height can be used for receiving the bearing ring, without the need for frequent replacement of the material frame 7, greatly saving manpower and improving the efficiency of blanking. The utility model is matched with the material frame 7 with a higher height by the setting of lifting structure 4 and baffle 5. Because the material frame 7 with a higher height is easily subjected to knocking and extrusion between the bearing rings during the process of blanking the bearing rings into the material frame 7, the quality of the bearing rings is greatly affected, and a lot of noise is generated. After the setting of lifting structure 4 and baffle 5, the bearing rings always pass through the buffer of baffle 5 before dropping into the material frame 7, reducing the knocking between the bearing rings, lowering the noise generated by the knocking of the dropping bearing rings, and pushing the bearing rings accumulated on the left side of baffle 5 to the right side of baffle 5 during the lifting of baffle 5. The lifting speed of baffle 5 can be set to be slow, and the space on the right side of baffle 5 is filled by this way, further reducing the knocking and noise, and the space on the right side of baffle 5 will not be filled with bearing rings due to the setting of baffle 5.

[0026] Lifting structure 4 includes a through-shaft type lead screw stepper motor 8 fixed on support plate 3, a lead screw 9 penetrates the center of through-shaft type lead screw stepper motor 8, and the lower end of lead screw 9 is fixed with baffle 5. This is one type of lifting structure 4. Alternatively, lifting structure 4 can be set as a gas cylinder, and baffle 5 is fixed on the end of the telescopic rod of the gas cylinder. The lifting of baffle 5 is realized by the extension and retraction of the telescopic rod of the gas cylinder.

[0027] The baffle 5 is provided with a diffuse reflection photoelectric switch 10. By arranging the diffuse reflection photoelectric switch 10, the diffuse reflection photoelectric switch 10 detects the distance, judges the stacking height of the material, and then the lifting structure 4 drives the baffle 5 to automatically rise to the appropriate position, so that the stacking height of the material can be judged at any time until the stacking height of the material reaches the set threshold value, at which time the lifting structure 4 is started to drive the baffle to rise.

[0028] The lower end of the lead screw 9 is fixed at the center of a connecting block 11, the connecting block 11 is fixed at the right middle position of the baffle 5, and the diffuse reflection photoelectric switch 10 is fixed on the upper surface of the connecting block 11. By arranging the connecting block 11, the fixation between the lead screw 9 and the baffle 5 is more firm. The connecting block 11 is fixed at the right middle position of the baffle 5, so that the connecting block 11 and the lead screw 9 do not affect the discharging of the bearing ring. The diffuse reflection photoelectric switch 10 is arranged on the connecting block 11, so that the diffuse reflection photoelectric switch 10 will not be hit by the bearing ring, which provides good protection for the diffuse reflection photoelectric switch 10.

[0029] The baffle 5 includes a first steel plate 12 and a second steel plate 13, and a plurality of springs 14 are fixed between the first steel plate 12 and the second steel plate 13. The upper surface of the second steel plate 13 is fixed with a rubber block 15, and the upper surface of the rubber block 15 is fixed with a sponge shock-absorbing plate 16. The baffle 5 of this structure has a strong shock-absorbing effect. The sponge shock-absorbing plate 16 directly contacts the bearing ring, so that when the bearing ring falls onto the sponge shock-absorbing plate 16, on the one hand, the soft sponge shock-absorbing plate 16 provides good protection for the bearing ring and does not cause the bearing ring to be hit by a rigid object, and on the other hand, the soft and porous structure of the sponge shock-absorbing plate 16 provides good speed reduction for the bearing ring, making the falling process into the feed frame 7 more gentle, thereby further reducing the impact and noise.

[0030] The upper surface of the sponge shock-absorbing plate 16 is arranged in a wave shape. By arranging the upper surface of the sponge shock-absorbing plate 16 in a wave shape, the friction between the bearing ring and the sponge shock-absorbing plate 16 is further increased, thereby enhancing the buffering effect.

[0031] The top end of the lead screw 9 is fixed with a limiting block 17, which prevents the through-shaft lead screw stepper motor 8 and the lead screw 9 from being separated.

[0032] The surface of the conveying belt 18 of the lifting conveyor 1 is uniformly distributed with a plurality of ribs 19, the setting of the ribs 19 can prevent the bearing ring on the lifting conveyor 1 from sliding down from the conveying belt 18 during lifting, and the ribs 19 can be made of rubber to prevent the bearing ring from being scratched by the ribs 19.

[0033] Working principle: when working, the bearing ring after heat treatment by the roller net belt furnace is conveyed to the lifting conveyor 1, the bearing ring on the lifting conveyor 1 is lifted to the right upper end and then falls down to the guide plate 6, the guide plate 6 is set to be inclined from left to right, the bearing ring on the guide plate 6 slides to the baffle 5 in front of the guide plate 6, and then enters the material frame 7, when the material is discharged for a period of time, the lifting structure 4 starts to lift the baffle 5 upward by a distance, and in this way, the lifting structure 4 lifts upward by a distance at intervals during the discharging process until the material frame 7 is filled with material. In order to prevent the bearing ring on the guide plate 6 from falling off from the front and rear edges of the guide plate 6, side baffles can be fixed on the front and rear edges of the guide plate 6. In order to facilitate the movement and fixation of the material frame 7, universal wheels can be arranged at the four corners of the bottom surface of the material frame 7, and brake pads are arranged on the universal wheels. The bearing ring is lifted to a height by the setting of the lifting conveyor 1, so that a material frame 7 with a higher height can be used for receiving the material, the material frame 7 does not need to be frequently replaced, the manpower is greatly saved, and the discharging efficiency is improved. The lifting structure 4 and the baffle 5 are matched with the material frame 7 with a higher height, because the bearing ring is easily knocked and pressed with each other during the process of discharging the bearing ring into the material frame 7 with a higher height, which greatly affects the quality of the bearing ring and produces a lot of noise. After the setting of the lifting structure 4 and the baffle 5, the bearing ring always passes through the buffer of the baffle 5 before falling into the material frame 7, which reduces the knocking between the bearing rings and reduces the noise caused by the knocking of the falling bearing rings. In addition, the bearing rings accumulated on the left side of the baffle 5 are pushed to the right side space as the baffle 5 rises, the rising speed of the baffle 5 can be set to be slow, and the space on the right side of the baffle 5 is further reduced by this way, which reduces the knocking and noise, and the space on the right side of the baffle 5 cannot be filled with the bearing rings due to the setting of the baffle 5.

[0034] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
