Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1 to 6, a presser foot mechanism of an automatic sole roughing machine corresponds to a shoe mold a of the automatic sole roughing machine up and down, and is installed on a machine frame 1 above the shoe mold a and a workbench 2 through a support plate 3, a base plate B5 is fixed on the support plate 3, a vertical sliding sleeve B4 and a lifting cylinder B1 are installed on the base plate, a lifting shaft B3 is installed in the vertical sliding sleeve, a top rod of the lifting cylinder B1 is arranged upwards and is connected with the upper end of the lifting shaft through a connecting plate B2, a presser foot B6 is rotatably installed at the lower end of the lifting shaft, and the lifting shaft drives the presser foot to press down, so that a sole is pressed on the shoe mold a.
The presser foot comprises the following structure: the fixed block B6.1 is horizontally arranged, is sleeved at the lower end of the lifting shaft through a hole formed in the middle and is fixed by a screw B7, and two ends of the fixed block are outwards suspended; the upper rotating plate B6.4 is horizontally arranged below the fixed block, and the middle part of the upper rotating plate is rotatably matched with the lower end of the lifting shaft through a bearing; the lower lifting plate B6.9 corresponds to the upper lifting plate up and down, the upper lifting plate and the lower lifting plate are connected through guide pins B6.3 at two ends, and springs B6.7 are sleeved on the guide pins; and the pressing plate B6.12 is fixedly connected with the bottom surface of the lower lifting plate and is adaptive to the shape of the sole.
And magnets B6.2 are respectively arranged at the bottom of the fixed block and the top of the upper rotating plate, and the two magnets correspond to each other up and down and have opposite polarities. The magnet is used for resetting the upper rotating plate, and when the upper rotating plate rotates for a certain angle, the upper rotating plate can return to the original position under the action of the magnet.
The top of the guide pin is provided with a conical head B6.3.1, the diameter of the bottom of the guide pin is reduced to form a reducing section B6.6, the reducing section is provided with an axial threaded hole, the top surface of the upper rotating plate is provided with a conical hole B6.5 matched with the conical head (the inner diameter of the bottom of the conical hole is slightly larger than the outer diameter of the guide pin), the guide shaft penetrates through the conical hole of the upper rotating plate from top to bottom, the reducing section is inserted into a through hole formed in the lower lifting plate, and the bottom of the lower lifting plate is provided with a screw B6.8 screwed in the threaded hole, so that the lower lifting plate is fixed in the reducing section. When the lower lifting plate is stressed to rise, the spring is compressed, the guide pin rises along with the lower lifting plate, when the lower lifting plate loses pressure, the spring forces the lower lifting plate to reset, the guide pin descends along with the lower lifting plate, and the lower lifting plate is centered through the conical head and the conical hole, so that the lower lifting plate resets at the same position every time. In addition, because the sole is thick and thin, the sole part is thinner than the heel part, at the moment, the lower lifting plate slightly inclines, the guide pin can slightly incline in the conical hole (the upper rotating plate can not incline), the shoe sole is suitable for the unevenness of the sole, and the lifting shaft is not influenced. In addition, the arrangement of the spring can enable the presser foot to have a buffering function, and the rigid collision between the presser foot and the sole is avoided.
Magnets B6.13 (the pressing plate is an iron piece) for adsorbing the pressing plate are embedded in the left side and the right side of the lower lifting plate, an embedding hole B6.10 is formed in the pressing plate, and the head of a screw is embedded into the embedding hole, so that the pressing plate is fixed to the bottom of the lower lifting plate (obviously, the pressing plate can also be fixed to the bottom of the lower lifting plate in a screw or welding mode and the like, which is a conventional means and is not described in detail). And an avoiding hole B6.11 for avoiding the diameter reducing section is formed in the middle of the lower lifting plate.
A worker or automatic feeding equipment sends the sole to a shoe mold; start the lift cylinder, push down the presser foot, compress tightly the sole, beat the antedisplacement of thick mechanism, when profiling and positioning die are rotatory, beat thick mechanism and begin to beat thick to the sole border, go up the rotor plate, lower rotor plate and clamp plate can follow the shoe mold and rotate, beat thick mechanism and can polish at least once with the whole border of sole, beat thick completion back, beat thick mechanism and shift backward, the presser foot is pulled up to the lift cylinder, workman or automatic feeding equipment take off the sole.
The above description is only a preferred embodiment of the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
