Detailed implementation manners

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0031] The left-right, up-down positions of the various components shown in the drawings are only an arrangement method, and the specific positions are set according to specific needs.

[0032] In one embodiment, as Figures 1 - 6As shown in the figure, a grinding device for the production of rubber rollers includes a main bearing frame 100, a belt conveying assembly 200 and a grinding frame 400. The belt conveying assembly 200 is installed on the main bearing frame 100, and the grinding frame 400 is arranged at the middle position of the belt conveying assembly 200, and the grinding frame 400 laterally straddles the upper side of the belt conveying assembly 200. It also includes side bearing waist discs 300, a grinding mechanism 500 and a plurality of bearing components 700. There are two side bearing waist discs 300, which are symmetrically arranged on both sides of the belt conveying assembly 200 respectively. The bearing component 700 includes two bearing seats 710 that can slide on the edges of the two side bearing waist discs 300 respectively. The bearing seats 710 are connected to the belt conveying assembly 200, and the belt conveying assembly 200 can drive the bearing seats 710 to move cyclically along the edges of the side bearing waist discs 300. Each bearing seat 710 has a lower semi-circular groove, and a rotatable and movable lower semi-circular movable clamping ring 730 is installed in the lower semi-circular groove. The lower semi-circular movable clamping ring 730 is used to support the rubber roller end head 910 at the end of the rubber roller body 900. The grinding mechanism 500 includes a movable frame body 510, an upper clamping seat 520, a grinding execution part 530 and a grinding drive part. The movable frame body 510 is located above the belt conveying assembly 200, and the top of the movable frame body 510 is connected to the grinding cylinder part 600 arranged on the grinding frame 400. There are two upper clamping seats 520, which are symmetrically arranged at both ends of the movable frame body 510. The upper clamping seats 520 correspond to the bearing seats 710 passing under them. The lower end surface of the upper clamping seat 520 has an upper semi-circular groove that cooperates with the lower semi-circular groove to form a circular cavity. There is a rotatable and movable upper semi-circular movable clamping ring 521 in the upper semi-circular groove. When the upper clamping seat 520 is aligned with and contacts the bearing seat 710, the upper semi-circular movable clamping ring 521 and the lower semi-circular movable clamping ring 730 in the bearing seat 710 can form a rotating ring for clamping the rubber roller end head 910. The grinding execution part 530 can slide on the movable frame body 510, and the lower surface of the grinding execution part 530 can abut against the outer surface of the rubber roller body 900. The grinding drive part is arranged on the movable frame body 510. The grinding execution part 530 and the two upper semi-circular movable clamping rings 521 are both connected to the grinding drive part. The grinding drive part drives the grinding execution part 530 to move along the width direction of the belt conveying assembly 200 while also driving the upper semi-circular movable clamping ring 521 and the corresponding lower semi-circular movable clamping ring 730 to rotate in the circular cavity.

[0033] In an embodiment of the present invention, the rubber roller main body 900 is placed on the bearing member 700 at the front end of the belt conveying assembly 200 manually or by using a manipulator. The rubber roller end heads 910 at both ends of the rubber roller main body 900 are respectively supported by two bearing seats 710 in the bearing member 700. The belt conveying assembly 200 conveys the bearing member 700 and the rubber roller main body 900 along the edge of the side bearing waist disc 300 to the grinding area where the grinding mechanism 500 is located. When the rubber roller main body 900 is in the grinding area, the bearing seat 710 just corresponds to the upper clamping seat 520. The grinding cylinder part 600 starts to work and pushes the grinding mechanism 500 to move downward by elongation. The upper clamping seat 520 contacts the corresponding bearing seat 710, and the upper semi-circular movable clamping ring 521 clamps the rubber roller end head 910 in the lower semi-circular movable clamping ring 730 from the upper side. The upper semi-circular movable clamping ring 521 and the lower semi-circular movable clamping ring 730 clamp the rubber roller end head 910 tightly. At this time, the bottom of the grinding execution part 530 abuts against the outer surface of the rubber roller main body 900. The grinding driving part works, and the power unit 550 drives the two upper semi-circular movable clamping rings 521 to rotate. The upper semi-circular movable clamping ring 521 and the corresponding lower semi-circular movable clamping ring 730 rotate in the circular cavity formed by the lower semi-circular groove and the upper semi-circular groove. The upper semi-circular movable clamping ring 521 and the lower semi-circular movable clamping ring 730 drive the rubber roller end head 910 and the rubber roller main body 900 to rotate. The grinding driving part also acts on the grinding execution part 530 and makes the grinding execution part 530 move along the axial direction of the rubber roller main body 900. Therefore, the grinding execution part 530 performs a comprehensive grinding work on the surface of the rubber roller main body 900 by abutting against the surface of the rubber roller main body 900. During the grinding process, the upper semi-circular movable clamping ring 521 and the lower semi-circular movable clamping ring 730 always clamp the rubber roller end head 910 tightly to limit the axial movement of the rubber roller main body 900, ensure the uniform axial movement of the grinding execution part 530 relative to the surface of the rubber roller main body 900, and ensure the grinding effect. At the same time, the waste chips generated by the grinding execution part 530 acting on the surface of the rubber roller main body 900 fall onto the upper surface of the belt conveying assembly 200. After the grinding is completed, the grinding driving part stops working, and the lower semi-circular movable clamping ring 730 and the upper semi-circular movable clamping ring 521 are respectively in the corresponding lower semi-circular groove and upper semi-circular groove. The grinding cylinder part 600 works and drives the grinding mechanism 500 to move upward by contraction. The upper clamping seat 520 is separated from the corresponding bearing seat 710. Since the lower semi-circular movable clamping ring 730 and the upper semi-circular movable clamping ring 521 are respectively in the corresponding lower semi-circular groove and upper semi-circular groove, the lower semi-circular movable clamping ring 730 and the upper semi-circular movable clamping ring 521 are separated and no longer clamp the rubber roller end head 910. The belt conveying assembly 200 works, and then the rubber roller main body 900 that has been ground is sent to the tail of the belt conveying assembly 200, and the rubber roller main body 900 to be ground is sent to the lower side of the grinding mechanism 500 to facilitate the realization of automatic grinding work;When the carrying component 700 moves to the tail of the belt conveying component 200 and rotates to the lower side of the belt conveying component 200, the rubber roller body 900 can automatically disengage from the carrying seat 710 to achieve automatic blanking. At the same time, there is a waste slot 110 at the tail position of the belt conveying component 200, and the waste on the belt conveying component 200 can fall from its tail into the waste slot 110 for unified collection, avoiding the problem that the waste generated by grinding is not easy to clean up.

[0034] In one embodiment, as Figures 1 - 6 shown, one end of the lower semi-circular movable snap ring 730 extends to the side of the carrying seat 710 and has a lower semi-circular rack 760. At least one positioning tooth body 770 is arranged on the side of the carrying seat 710, and the positioning tooth body 770 is rotatably connected to the side of the carrying seat 710 through a fulcrum shaft. One end of the upper semi-circular movable snap ring 521 extends to the side of the upper clamping seat 520 and has an upper semi-circular rack 522. The upper semi-circular rack 522 and the lower semi-circular rack 760 can be buckled into a toothed ring. The grinding drive part includes a screw member 540 and a power unit 550. The screw member 540 is rotatably arranged on the movable frame body 510 and is connected to the grinding execution part 530. The power unit 550 is arranged on the side of the movable frame body 510, and the power unit 550 is connected to the upper semi-circular rack 522 and can drive the rotating ring formed by the upper semi-circular rack 522 and the lower semi-circular movable snap ring 730 to rotate in the circular cavity. The screw member 540 is connected to the power unit 550 and rotates under the action of the power unit 550. In the embodiment of the present invention, the power unit 550 works and drives the rotating ring formed by the upper semi-circular rack 522 and the lower semi-circular movable snap ring 730 to rotate in the circular cavity, thereby driving the end head 910 of the rubber roller and the rubber roller body 900 to rotate. At the same time, the power unit 550 also acts on the screw member 540 to make it rotate, and the rotating screw member 540 drives the grinding execution part 530 to move along the axis of the rubber roller body 900. The rotation of the rubber roller body 900 in cooperation with the axial movement of the grinding execution part 530 can achieve comprehensive grinding of the outer wall of the rubber roller body 900.

[0035] In one embodiment, as Figures 1 - 6As shown, the power unit 550 includes a grinding motor 551 and two transmission parts. The grinding motor 551 is arranged on the side of the movable frame 510 and the output end of the grinding motor 551 is connected to one section of the screw member 540 through the upper gear pair 553. The two transmission members are respectively arranged at the two ends of the movable frame 510. The transmission members include a tensioning shaft 552 and two external transmission shafts 554. The tensioning shaft 552 is rotatably matched with the movable frame 510. The two external transmission shafts 554 are rotatably arranged on the upper clamping seat 520 and are symmetrically located on the upper semicircular movable clamping seat. The tensioning shaft 552 is located between the two outer transmission shafts 554, and the screw rod 540, the tensioning shaft 552 and the two outer transmission shafts 554 are connected by a belt transmission member 555; the outer transmission shaft 554 is also provided with a rotating gear 556 that can mesh with the upper semicircular rack 522 and the lower semicircular rack 760; in the embodiment of the present invention, the grinding motor 551 is a servo motor and its output end can realize positive and negative rotation under the action of the controller; the output end of the grinding motor 551 acts on the screw rod through the upper gear pair 553 The screw member 540 is rotated to make it rotate, and the rotating screw member 540 acts on the grinding execution part 530 to make the grinding execution part 530 move along the axis of the rubber roller body 900; at the same time, the screw member 540 acts on the two external transmission shafts 554 through the power unit 550, and the two external transmission shafts 554 rotate and mesh with the upper semicircular rack 522 and the lower semicircular rack 760 through the rotating gear 556, so that the rotating ring makes the rubber roller body 900 rotate, so that the outer surface of the rubber roller body 900 can be fully ground, and at the same time, it is ensured that The linkage between the rotation of the rubber roller body 900 and the axial movement of the grinding actuator 530 improves the coordination between the feed and the rotation during grinding, so that when the grinding is stopped later, the upper semicircular movable snap ring 521 and the lower semicircular movable snap ring 730 respectively rotate to the upper semicircular groove and the lower semicircular groove to achieve rapid separation of the upper clamping seat 520 and the bearing seat 710; the setting of the tensioning shaft 552 can realize the tensioning of the belt transmission member 555 and change the circumferential direction of the belt in the belt transmission member 555, avoiding interference between the belt transmission member 555 and the upper semicircular movable snap ring 521.

[0036] In one embodiment, Figures 1 - 6As shown, the bottom of the carrier seat 710 has a sliding seat 720, and the sliding seat 720 is sleeved on the edge of the side carrier waist disc 300; a lower elastic rod 780 is arranged on the sliding seat 720, and the end of the lower elastic rod 780 away from the sliding seat 720 has a follower roller 790; a guiding closed groove 310 having the same shape as the side carrier waist disc 300 is arranged on the outer surface of the side carrier waist disc 300, a positioning groove 320 is opened on the side wall of the guiding closed groove 310 away from the edge of the side carrier waist disc 300, and a pressure sensor is arranged in the positioning groove 320; the follower roller 790 extends into the guiding closed groove 310 and moves along the direction of the guiding closed groove 310. When the lower elastic rod 780 moves to a position corresponding to the positioning groove 320, the carrier seat 710 corresponds to the upper clamping seat 520; in the embodiment of the present invention, the belt conveying assembly 200 drives the carrier seat 710 to move along the edge of the side carrier waist disc 300, and the lower elastic rod 780 and the follower roller 790 move along with the carrier seat 710. Since the shape of the guiding closed groove 310 is the same as the shape of the edge of the side carrier waist disc 300, the follower roller 790 is always inside the guiding closed groove 310, and under the elastic force of the lower elastic rod 780, the outer wall of the follower roller 790 always abuts against the inner wall of the guiding closed groove 310 away from the edge of the side carrier waist disc 300; when the carrier seat 710 moves to a position corresponding to the upper clamping seat 520, the follower roller 790 moves to the positioning groove 320 and under the elastic force of the lower elastic rod 780, the follower roller 790 is clamped into the positioning groove 320, and the pressure sensor in the positioning groove 320 generates an induction signal. At this time, the belt conveying assembly 200 stops working; furthermore, the rubber roller main body 900 moves to directly below the grinding execution part 530; it can effectively ensure the contact between the carrier seat 710 and the upper clamping seat 520 and the cooperation between the lower semi-circular movable clamping ring 730 and the upper semi-circular movable clamping ring 521, and realize precise positioning.

[0038] In one embodiment, as Figures 1 - 6As shown, the belt conveying assembly 200 includes a pulley part 210, a conveying motor 220, and a conveyor belt 230. There are two pulley parts 210, which are respectively arranged at both ends of the main bearing frame 100. The end of the pulley part 210 rotates through the center of the circular end of the side bearing waist disc 300. The output end of the conveying motor 220 is connected to the end of one of the pulley parts 210. The conveyor belt 230 is wound around the outside of the two pulley parts 210, and the conveyor belt 230 has a transverse skeleton structure inside.

The pulley part 210 acts on the conveyor belt 230 to make it move in a cycle around the two pulley parts 210. The moving conveyor belt 230 drives the bearing component 700 to move along the edge of the side bearing waist disc 300 through its own skeleton structure. Among them, the skeleton structure of the conveyor belt 230 is a plurality of cross bars arranged inside the conveyor belt 230 to increase the strength of the conveyor belt 230 and prevent the conveyor belt 230 from deforming when driving the bearing component 700 to move.

[0039] In one embodiment, as Figures 1 - 7 shown, the movable frame body 510 has at least one guide rod 511. The grinding execution part 530 includes an upper feed frame 531 and a grinding piece 534. The upper feed frame 531 is provided with a spiral seat 532 and at least one feed sliding sleeve 533. The feed sliding sleeve 533 is slidably matched with the guide rod 511, and the spiral seat 532 is helically matched with the lead screw part 540. The grinding piece 534 is located below the upper feed frame 531, and both ends of the grinding piece 534 have suspension rods 535. The top of the suspension rod 535 penetrates through the upper feed frame 531, and the suspension rod 535 is provided with a contact inductor 537. A contact spring 536 surrounding the outside of the suspension rod 535 is arranged between the grinding piece 534 and the upper feed frame 531. In the embodiment of the present invention, when the movable frame body 510 moves downward, the upper feed frame 531 and the grinding piece 534 move accordingly. The grinding piece 534 is attached to the arc top of the rubber roller main body 900. Due to the elastic force of the contact spring 536, the grinding piece 534 is in a contact state with the arc top of the rubber roller main body 900, so that during grinding, the grinding piece 534 is always in contact with the arc top of the rubber roller main body 900 to ensure the uniformity of grinding. The contact inductor 537 is used to sense the contact pressure between the grinding piece 534 and the rubber roller main body 900. Due to the helical fit between the spiral seat 532 and the lead screw part 540, when the lead screw part 540 rotates, it can drive the spiral seat 532 to move along the width direction of the belt conveying assembly 200, that is, the entire grinding execution part 530 moves along the axis direction of the rubber roller main body 900.

[0040] In one embodiment, as Figures 1 - 8As shown, the grinding mechanism 500 further includes two symmetrically arranged rubber roller centering components 560 on the grinding mechanism 500. The rubber roller centering component 560 includes an arc-shaped centering plate 561 and a centering rod 562. The end of the centering rod 562 has a centering sliding sleeve 564 that slidably cooperates with the guide rod 511. The centering rod 562 is connected to the end of the movable frame body 510 through a centering spring 565. A downwardly extending centering connecting rod 563 is fixed at the middle position of the centering rod 562. The arc-shaped centering plate 561 is fixed on the centering connecting rod 563, and both ends of the arc-shaped centering plate 561 extend towards the side bearing waist disc 300. The center of the end face of the arc-shaped centering plate 561 facing the grinding execution part 530 has a pressure stroke sensor. The pressure stroke sensor is electrically connected to the power unit 550. In the embodiment of the present invention, when the rubber roller main body 900 gradually approaches the grinding area where the grinding mechanism 500 is located and the middle of the rubber roller main body 900 is not at the middle line position of the belt conveying component 200, one end of the rubber roller main body 900 will contact the outer arc surface of one of the arc-shaped centering plates 561. As the rubber roller main body 900 moves, pressure is generated between the end of the rubber roller main body 900 and the arc-shaped centering plate 561. Under the elastic force of the centering spring 565, the arc-shaped centering plate 561 will push the rubber roller main body 900 to move axially, and the other end of the rubber roller main body 900 will gradually approach and abut against the outer arc surface of the arc-shaped centering plate 561 in the other rubber roller centering component 560. After the rubber roller main body 900 moves to directly below the grinding execution part 530, the two arc-shaped centering plates 561 respectively apply equal abutting forces to both ends of the rubber roller main body 900. Since the elastic coefficients of the centering springs 565 in the two rubber roller centering components 560 are the same and the compressed lengths of the centering springs 565 are the same, the middle of the rubber roller main body 900 is aligned with the middle line of the belt conveying component 200, realizing automatic centering. When the grinding execution part 530 moves along the axis of the rubber roller main body 900 to the end of the rubber roller main body 900 driven by the lead screw member 540, the grinding execution part 530 will touch the pressure stroke sensor on the arc-shaped centering plate 561. The pressure stroke sensor generates an induction signal and controls the working state of the power unit 550. The power unit 550 drives the lead screw member 540 to rotate, and the grinding execution part 530 moves back and reciprocally grinds the outer wall of the rubber roller main body 900, so that the length of each round-trip movement stroke can be automatically set according to the actual length of the rubber roller main body 900, avoiding the no-load operation of the power unit 550 and avoiding the non-contact grinding of the grinding execution part 530 and the outer wall of the rubber roller main body 900, improving the grinding efficiency and saving no-load consumption.

[0041] In one embodiment, as Figure 1 、 Figure 2 and Figure 9As shown, a blanking component 800 is further provided on the main carrying frame body 100 at the tail end of the belt conveying component 200. The blanking component 800 includes a U-shaped material supporting rod frame 830 and two blanking inclined supporting rods 810. The two blanking inclined supporting rods 810 are respectively arranged at the ends of the two side carrying waist discs 300, and the blanking inclined supporting rods 810 are fixedly connected to the main carrying frame body 100 through avoiding connecting rods 820. The U-shaped material supporting rod frame 830 is arranged at the end of the blanking inclined supporting rod 810 away from the belt conveying component 200, and the U-shaped material supporting rod frame 830 is connected to both blanking inclined supporting rods 810. In the embodiment of the present invention, the rubber roller body 900 that has been ground is moved to the tail of the belt conveying component 200 under the conveying of the belt conveying component 200 and the carrying component 700. The carrying component 700 gradually rotates to the lower side of the belt conveying component 200. The rubber roller body 900 disengages from the carrying component 700, and the rubber roller end head 910 rolls onto the blanking inclined supporting rod 810. Then, the rubber roller body 900 slides along the blanking inclined supporting rod 810 to the U-shaped material supporting rod frame 830, so as to be conveniently stored uniformly and provide convenience for subsequent processing.

[0042] In one embodiment, as Figure 1 、 Figure 2 and Figure 9 shown, the U-shaped material supporting rod frame 830 is provided with a connecting portion 840 at the end facing the blanking inclined supporting rod 810, and the connecting portion 840 extends to the lower side of the tail end of the blanking inclined supporting rod 810. The connecting portion 840 and the tail end of the blanking inclined supporting rod 810 are fastened together by a fastening bolt 850. In the embodiment of the present invention, since the U-shaped material supporting rod frame 830 and the blanking inclined supporting rod 810 are detachably connected through the connecting portion 840 and the fastening bolt 850, the U-shaped material supporting rod frame 830 can be disassembled, and the tail end of the blanking inclined supporting rod 810 can be connected to the feeding structure for other processed rubber roller bodies 900, so as to realize automatic feeding of subsequent processing equipment.

[0043] The above embodiment provides a grinding device for the production of rubber rollers. Among them, the rubber roller main body 900 is placed on the bearing member 700 at the front end of the belt conveying assembly 200. The rubber roller end heads 910 at both ends of the rubber roller main body 900 are respectively supported by two bearing seats 710 in the bearing member 700; the belt conveying assembly 200 conveys the bearing member 700 and the rubber roller main body 900 along the edge of the side bearing waist disc 300 to the grinding area where the grinding mechanism 500 is located; when the rubber roller main body 900 is in the grinding area, the bearing seat 710 just corresponds to the upper clamping seat 520. The grinding cylinder part 600 starts to work and pushes the grinding mechanism 500 to move downward by extending. The upper clamping seat 520 contacts the corresponding bearing seat 710, and the upper semi-circular movable clamping ring 521 clamps the rubber roller end head 910 in the lower semi-circular movable clamping ring 730 from the upper side. The upper semi-circular movable clamping ring 521 and the lower semi-circular movable clamping ring 730 clamp the rubber roller end head 910 tightly. At this time, the bottom of the grinding execution part 530 abuts against the outer surface of the rubber roller main body 900; the grinding drive part works, and the power unit 550 drives the two upper semi-circular movable clamping rings 521 to rotate. The upper semi-circular movable clamping ring 521 and the corresponding lower semi-circular movable clamping ring 730 rotate in the circular cavity formed by the lower semi-circular groove and the upper semi-circular groove. The upper semi-circular movable clamping ring 521 and the lower semi-circular movable clamping ring 730 drive the rubber roller end head 910 and the rubber roller main body 900 to rotate. The grinding drive part also acts on the grinding execution part 530 and makes the grinding execution part 530 move along the axis direction of the rubber roller main body 900. Therefore, the grinding execution part 530 comprehensively grinds the surface of the rubber roller main body 900 by abutting against the surface of the rubber roller main body 900; during the grinding process, the upper semi-circular movable clamping ring 521 and the lower semi-circular movable clamping ring 730 always clamp the rubber roller end head 910 tightly to limit the axial movement of the rubber roller main body 900, ensure the uniform axial movement of the grinding execution part 530 relative to the surface of the rubber roller main body 900, ensure the grinding effect. At the same time, the waste chips generated by the grinding execution part 530 acting on the surface of the rubber roller main body 900 fall onto the upper surface of the belt conveying assembly 200; after the grinding is completed, the grinding drive part stops working, and the lower semi-circular movable clamping ring 730 and the upper semi-circular movable clamping ring 521 are respectively in the corresponding lower semi-circular groove and upper semi-circular groove; the grinding cylinder part 600 works and drives the grinding mechanism 500 to move upward by contracting, and the upper clamping seat 520 is separated from the corresponding bearing seat 710; since the lower semi-circular movable clamping ring 730 and the upper semi-circular movable clamping ring 521 are respectively in the corresponding lower semi-circular groove and upper semi-circular groove; the lower semi-circular movable clamping ring 730 and the upper semi-circular movable clamping ring 521 are separated and the two no longer clamp the rubber roller end head 910; the belt conveying assembly 200 works, and then the rubber roller main body 900 that has been ground is sent to the tail of the belt conveying assembly 200, and the rubber roller main body 900 to be ground is sent to the lower side of the grinding mechanism 500 to facilitate the realization of automatic grinding work;When the carrier member 700 moves to the tail of the belt conveying assembly 200 and rotates to the lower side of the belt conveying assembly 200, the rubber roller body 900 can automatically disengage from the carrier seat 710 to achieve automatic blanking. At the same time, a waste slot 110 is provided at the tail position of the belt conveying assembly 200, and the waste on the belt conveying assembly 200 can fall from its tail into the waste slot 110 for unified collection, avoiding the problem that the waste generated by grinding is not easy to clean up.
