Description

Technical Field

[0001] The utility model relates to the field of lasting machines, in particular to a disc rotating mechanism of lasting machines. Background Art

[0002] The upper of injection molded shoes is generally first formed on the upper mold, and then the upper mold and the upper are put into the injection molding machine together to injection mold the sole so that the sole and the upper are firmly bonded together. Since a lot of labor is reduced in the production process, the price is affordable, and since no glue is used in the sole molding process, the harm of glue to the human body can be avoided.

[0003] In order to achieve semi-automatic or even automated production, multiple sets of sole mold clamping mechanisms and shoe lasts can be set on a rotating platform, and each clamping mechanism and shoe last are evenly distributed around the rotating platform. The traditional rotating platform is driven by a motor, and an additional deceleration and torque increase structure is required, which is complex in structure; secondly, the motor itself does not have a braking structure and is not suitable for driving the rotating platform to perform intermittent rotational motion. When the rotating platform is in the process of rotating and braking, it is easy to shake. Utility Model Content

[0004] The utility model aims to provide a disc rotating mechanism of a lasting machine, which has a simple structure and high stability when performing intermittent rotation.

[0005] To achieve the above-mentioned purpose, the utility model provides a disc rotating mechanism of a lasting machine, comprising a base, a transmission ring rotatably connected to the base, a disc connected to the transmission ring, a plurality of pin holes are provided on the outer peripheral wall of the transmission ring, and the pin holes are evenly distributed around the center of the transmission ring; an intermittent transmission ring toggle mechanism is connected to the base, and the intermittent transmission ring toggle mechanism cooperates with the pin holes of the transmission ring.

[0006] As a further improvement of the present invention, the intermittent transmission ring toggle mechanism includes a first hydraulic cylinder, one side of the first hydraulic cylinder is connected to the base through a hinged seat, the other end of the first hydraulic cylinder is hinged with a toggle seat, and the toggle seat is slidingly matched with the outer wall of the transmission ring; a second hydraulic cylinder is connected to the toggle seat, and the output end of the second hydraulic cylinder is connected to a pin, which is plug-fitted with the pin hole of the transmission ring.

[0007] As a further improvement of the present invention, the transmission ring includes a downwardly protruding arc structure, a concave guide groove is provided in the middle of the toggle seat, the arc structure of the transmission ring slides with the guide groove of the toggle seat, and the pin hole is arranged on the arc structure of the transmission ring.

[0008] As a further improvement of the utility model, a one-way deceleration valve is provided on the base, and a swing arm is provided at the operating end of the one-way deceleration valve; a shift block is provided on the shift seat, and the swing arm is in contact with the shift block; the one-way deceleration valve is connected to the first hydraulic cylinder through a hydraulic pipe.

[0009] Beneficial Effects

[0010] Compared with the prior art, the advantages of the disc rotating mechanism of the lasting machine of the utility model are:

[0011] 1. An intermittent transmission ring toggle mechanism is connected to the base. The intermittent transmission ring toggle mechanism cooperates with the pin hole of the transmission ring to drive the transmission ring to perform intermittent rotation. The main driving mechanism of the intermittent transmission ring toggle mechanism adopts the first hydraulic cylinder, which has a simple structure and high stability when performing intermittent rotation.

[0012] 2. Since the toggle seat is in sliding cooperation with the outer wall of the transmission ring, when the first hydraulic cylinder drives the toggle seat to move, it can ensure that the toggle seat is always in contact with the outer wall of the transmission ring.

[0013] 3. When the first hydraulic cylinder contracts and pulls the transmission ring to rotate through the pin of the second hydraulic cylinder on the toggle seat, the toggle block on the toggle seat toggle the swing arm of the one-way speed reduction valve to one side, and the oil circuit switch in the one-way speed reduction valve is gradually closed until the first hydraulic cylinder stops contracting, achieving smooth braking of the transmission ring. When the pin of the second hydraulic cylinder is disengaged from the pin hole of the transmission ring and the first hydraulic cylinder is extended, the toggle block on the toggle seat moves to the other side. At this time, the swing arm resets itself under the action of the one-way speed reduction valve, and the oil circuit switch in the one-way speed reduction valve is reopened.

[0023] Example

[0024] The specific implementation of the utility model is as follows Figures 1 to 6 As shown, a disc rotating mechanism of a lasting machine includes a base 41, a transmission ring 42 is rotatably connected to the base 41, a disc is connected to the transmission ring 42, and the rotation axis of the transmission ring 42 is arranged vertically. A plurality of pin holes 421 are arranged on the outer peripheral wall of the transmission ring 42, and each pin hole 421 is evenly distributed around the center of the transmission ring 42. An intermittent transmission ring toggle mechanism is connected to the base 41, and the intermittent transmission ring toggle mechanism cooperates with the pin holes 421 of the transmission ring 42.

[0025] The intermittent transmission ring toggle mechanism includes a first hydraulic cylinder 43, one side of which is connected to the base 41 through a hinge seat 431, and the other end of the first hydraulic cylinder 43 is hinged with a toggle seat 44, which is slidably matched with the outer wall of the transmission ring 42. A second hydraulic cylinder 45 is connected to the toggle seat 44, and a latch 451 is connected to the output end of the second hydraulic cylinder 45, and the latch 451 is plugged and matched with the pin hole 421 of the transmission ring 42. In this embodiment, the latch 451 is perpendicular to the rotation axis of the transmission ring 42.

[0026] The transmission ring 42 includes a circular arc structure protruding downward, and a concave guide groove 441 is provided in the middle of the toggle seat 44. The circular arc structure of the transmission ring 42 is slidably matched with the guide groove 441 of the toggle seat 44, and the pin hole 421 is provided on the circular arc structure of the transmission ring 42. The latch 451 is located in the toggle seat 44 and can pass through the guide groove 441 by linear reciprocating movement.

[0027] The base 41 is provided with a one-way deceleration valve 47, and the operating end of the one-way deceleration valve 47 is provided with a swing arm 471. The shifting seat 44 is provided with a shifting block 46, the swing arm 471 contacts the shifting block 46, and the one-way deceleration valve 47 is connected to the first hydraulic cylinder 43 through a hydraulic pipe.

[0028] like Figure 3 , 4As shown in Figure 6, when the first hydraulic cylinder 43 contracts and pulls the transmission ring 42 to rotate clockwise through the latch 451 of the second hydraulic cylinder 45 on the toggle seat 44, the toggle block 46 on the toggle seat 44 toggle the swing arm 471 of the one-way speed reduction valve 47 to swing counterclockwise, and the oil circuit switch in the one-way speed reduction valve 47 is gradually closed until the first hydraulic cylinder 43 stops contracting, thereby achieving stable braking of the transmission ring 42. When the latch 451 of the second hydraulic cylinder 45 is disengaged from the pin hole 421 of the transmission ring 42 and the first hydraulic cylinder 43 is extended, the transmission ring 42 does not rotate, and the toggle block 46 on the toggle seat 44 moves counterclockwise around the center of the transmission ring 42. At this time, the swing arm 471 swings clockwise and resets itself under the action of the one-way speed reduction valve, and the oil circuit switch in the one-way speed reduction valve 47 is reopened. The above actions are repeated many times, so that the multiple sets of shoe lasts, sole molds and clamping structures arranged on the transmission ring 42 can be intermittently rotated and moved to different workstations.
