DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] like Figure 1 and Figure 2 As shown, a circular leather cloth processing and handling device comprises: a base 1, the interior of the base 1 is hollow to form an accommodation space, a fixed seat 2 is arranged in the accommodation space, a column 3 is rotatably arranged on the fixed seat 2, the top of the column 3 extends to the top of the base 1, and a horizontal beam 4 is arranged on the top of the column 3. The column 3 is circular and rotates relative to the fixed seat 2. An inclined reinforcing beam 30 is arranged between the column 3 and the beam 4 to improve the support strength and stability.

[0032] like Figure 3 and Figure 4 As shown, a sector disk 5 is provided at one side of the bottom of the column 3, and a connecting column is provided at the center of the sector disk 5 for rotationally connecting with the base 1. A slide rail 6 is provided at the arc edge of the sector disk, and limit blocks 7 are provided at both ends of the arc edge of the sector disk 5. The limit blocks 7 are located at both ends of the slide rail 6 and are used to limit the sliding range of the sliding object on the slide rail 6.

[0033] An arc-shaped rack 8 is slidably arranged on the slide rail 6 . The length of the arc-shaped rack 8 is less than the arc length of the sector disk 5 . The arc-shaped rack 8 can slide back and forth on the slide rail 6 and can be blocked by the limit block 7 .

[0034] A relatively fixed and rotatable fixed gear 9 is provided on one side of the fixed seat 2 in the base 1. The fixed gear 9 meshes with the arc-shaped rack 8, and the other side of the fixed gear 9 meshes with the driving gear 29 sleeved on the bottom of the column 3 to achieve a transmission connection between the three.

[0035] A linear slide groove 10 is provided on the top surface of the sector disk 5. The linear slide groove 10 is provided along the radial direction of the sector disk 5 and is located in the middle of the sector disk 5. A slider 11 is provided in the linear slide groove 10 for sliding movement. A first rotating hinge 12 is provided on the slider 11 for rotation. The other end of the first rotating hinge 12 extends to the outside of the sector disk 5 and is hinged to the second rotating hinge 13. The other end of the second rotating hinge 13 is connected to the driving device provided in the base 1. The driving device drives the second rotating hinge 13 to rotate around its second end to drive the first rotating hinge 12 to move. The second end of the first rotating hinge 12 slides in the slide groove 10, thereby driving the sector disk 5 to rotate back and forth.

[0036] When the sector disk 5 rotates, the arc-shaped rack 8 meshes with the fixed gear 9 and does not rotate with the sector disk 5, but slides along the slide rail 6 until it contacts the limit block 7 at the end of the sector disk 5. After contact, it can no longer slide relative to each other. With the movement of the sector disk 5, the arc-shaped rack 8 drives the fixed gear 9 to rotate, and the fixed gear 9 drives the column 3 to rotate until the sector disk 5 rotates to the limit position; then the sector disk 5 rotates in the opposite direction, at which time, the arc-shaped rack 8 also slides relative to each other first, contacts the limit block 7, and then drives the fixed gear 9 to rotate. Whenever the arc-shaped rack 8 slides relative to the sector disk 5, the column 3 is in a suspended state, realizing intermittent reciprocating rotation of the two ends of the column 3.

[0037] like Figure 2 and Figure 5 As shown, a circular fixed plate 14 is arranged below the end of the cross beam 4 away from the column 3, and a lifting plate 15 that can be lifted is arranged below the fixed plate 14. A connecting seat 16 is fixedly connected to the center of the bottom of the lifting plate 15, and a plurality of intersecting connecting plates 17 are fixedly connected to the bottom of the connecting seat 16. Figure 6 As shown, the centers of several connecting plates 17 intersect with each other, and the intersection is fixedly connected to the bottom of the connecting seat 16. A connecting block 18 extending downward is provided at the end of the connecting plate 17, and the bottom of the connecting block 18 is fixedly connected to the transport plate 19. The bottom of the connecting block 18 is diffused to increase the connection area with the transport plate 19.

[0038] A lifting cylinder 31 is provided on the fixed plate 14, and the bottom end of the piston rod of the lifting cylinder 31 extends to the bottom of the fixed plate 14 and is fixedly connected to the top of the lifting plate 15. There are several lifting cylinders 31, which are distributed along the circumference of the fixed plate 14. The lifting cylinder 31 can drive the lifting plate 15 to rise and fall.

[0039] The connecting seat 16 is centrally rotatably provided with a shaft 20, the top of which extends to the top of the lifting plate 15 and is transmission-connected to a driving motor 21 disposed above the lifting plate 15, and the bottom of which extends to the bottom of the connecting plate 17, and a first connecting rod 22 perpendicular thereto is fixedly provided at the bottom thereof, and a second connecting rod 23 is hingedly connected to the other end of the first connecting rod 22. The driving motor 21 rotates to drive the first connecting rod 22 and the second connecting rod 23 to rotate.

[0040] The transport plate 19 is provided with four straight through grooves 24 arranged along its radial direction, and the four through grooves 24 are evenly distributed along the circumference of the transport plate 19 and penetrate the transport plate 19. Two moving rods 25 are slidably arranged in the through grooves 24, and the bottom ends of the moving rods 25 extend below the transport plate 19, and the top ends extend above the transport plate 19, and a limiting circular block 32 is arranged at the top ends to prevent the moving rods 25 from escaping from the through grooves 24.

[0041] A rhombus hinge frame 26 is provided below the moving rod 25 . The rhombus hinge frame 26 is composed of four hinge rods hinged to each other, and its two opposite vertices are respectively connected to the bottom ends of the two moving rods 25 , so that the rhombus hinge frame 26 can move along the through slot 24 with the moving rod 25 .

[0042] like Figure 8 As shown, there are several rhombus hinge frames 26, which are evenly distributed along the circumference of the transport plate 19, and the two vertices of two adjacent rhombus hinge frames 26 are hinged, and all the rhombus hinge frames 26 are combined to form a ring-shaped connecting portion. Fig. 9 As shown, a negative pressure suction rod 27 is provided at the apex hinge of two adjacent rhombus hinge frames 26. The negative pressure suction rod 27 penetrates the rhombus hinge frame 26 and rotates relative to each hinge rod. A negative pressure suction head 28 is provided at its bottom end, and the top end is bent and extended to the outside of the transport plate 19 to connect to an external air source. The negative pressure suction head 28 is distributed in a ring shape and can absorb the round leather cloth for easy transportation.

[0043] The end of the second connecting rod 23 is rotatably connected to the top end of one of the moving rods 25 , and the moving rod 25 is the one in the through slot 24 relatively close to the edge of the transport plate 19 .

[0044] like Figure 7 As shown, a circular cover plate 33 fixedly connected to the bottom of the transport plate 19 is provided, the circular cover plate 33 covers the outside of the rhombus hinge frame 26, and is provided with a plurality of through chutes 34, and the negative pressure suction rod 27 extends from the through chutes 34 to the outside of the circular cover plate 33. The circular cover plate 33 is used for isolation and protection.

[0045] Working process: The intermittent reciprocating mechanism in the base 1 drives the column 3, the beam 4 and each plate structure to and from the two stations. When each plate structure reaches a station, the intermittent reciprocating mechanism will be suspended, and the lifting cylinder 31 will work to drive the lifting plate 15 and the transport plate 19 to rise and fall. The transport plate 19 descends until the negative pressure suction head 28 contacts the surface of the leather cloth, and the circular leather cloth is sucked up by the negative pressure, and then the lifting cylinder 31 works to drive the transport plate 19 and the leather cloth to rise; at this time, the column 3 rotates under the drive of the intermittent reciprocating mechanism until it reaches another station.

[0046] When adjusting the diameter of the circle adsorbed by the negative pressure suction head 28, the driving motor 21 is used to drive the shaft 20 to rotate, and the shaft 20 drives the first connecting rod 22 and the second connecting rod 23 to rotate. The rotation of the second connecting rod 23 drives the moving rod 25 to move in the through groove 24, and the diamond hinge frame 26 moves synchronously with the moving rod 25 and deforms, so that the diamond hinge frames 26 are tightened or spread relative to each other, so as to drive the negative pressure suction heads 28 to move closer to or away from each other, so that the diameter of the adsorption ring composed of the negative pressure suction heads 28 becomes larger or smaller to adapt to circular leather cloths of different diameters.

[0047] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
