As shown in fig. 6 to 9, in the present embodiment, the diversion plate 213 is detachably connected to the rotary seat 221. The mode of detachable connection can be convenient for the operator to change the profile modeling subassembly 21 that matches according to the sole of different models, improves the general nature of equipment.

There may be various specific implementations of the detachable connection.

For example, as shown in fig. 6 and 7, in the present embodiment, a snap is provided between the diversion plate 213 and the rotary seat 221 to achieve the detachable connection. The detachable connection realized by the buckle piece can achieve the effect of quick detachment and improve the working efficiency.

Further, as shown in fig. 7 to 11, in the present embodiment, the locking member includes: an inverted button 2132 connected to the dividing plate 213, a stopper 2211 mounted to the rotary holder 221, and an elastic member 2212 connected to the stopper 2211. The rotary base 221 is provided with an avoiding groove 2213 into which the inverted buckle 2132 is inserted. The fixture block 2211 is arranged in the avoiding groove 2213. The elastic piece 2212 is used for pushing the fixture block 2211 to act so as to clamp the inverted buckle 2132. The profile module 21 can be quickly removed by pressing the block 2211 on the rotating base 221 to compress the elastic member 2212, so that the block 2211 is staggered with the inverted buckle 2132 on the diversion plate 213. In this embodiment, the elastic member 2212 is a spring accommodated in the space-saving groove 2213, and may be replaced with an elastic rubber block. In other embodiments, the fastening block 2211 may be hinged to the rotating base 221, and in this case, the elastic member 2212 is a torsion spring disposed at the hinge.

For another example, in other embodiments, the detachable connection between the diversion plate 213 and the rotation seat 221 may be realized by screws.

Further, the detachable connection between the diversion plate 213 and the rotary base 221 can be improved to improve the accuracy and speed of assembly. For example, in the present embodiment, the diversion plate 213 and the rotary base 221 are matched through the positioning pin and the positioning hole 2214 to achieve positioning. When the profiling assembly 21 and the rotating assembly 22 are assembled, the positioning pins and the positioning holes 2214 are used for realizing quick and accurate butt joint, and the assembling precision and speed are improved.

Further, as shown in fig. 8, the positioning pin (not shown) is disposed on the diversion plate 213, and the positioning hole 2214 is opened on the rotary base 221. In other embodiments, the positioning pin may be disposed on the rotating base 221, the positioning hole 2214 is opened on the diversion plate 213, and the positioning hole 2214 needs to be offset from the positioning hole 2131.

In addition, in order to ensure the assembling stability between the flow distribution plate 213 and the rotating base 221, in the present embodiment, a magnetic member is disposed between the flow distribution plate 213 and the rotating base 221. The magnetic attraction piece enhances the binding force between the diversion plate 213 and the rotation seat 221 through the magnetic attraction force, and improves the connection tightness between the profile modeling assembly 21 and the rotation assembly 22.

In the present embodiment, based on the detachability between the diverter plate 213 and the rotary base 221, it is necessary to consider the problem that the introduction of the detachability causes the airtightness between the rotation shaft 222 and the diverter plate 213 to be reduced, and therefore, a targeted improvement can be made.

For example, as shown in fig. 7 to 11, in the present embodiment, the shunt plate 213 is provided with a catching groove 2133. The air inlet end of 2131 extends to the catch 2133. The rotating base 221 is provided with a transition base 2216 for abutting against the clamping groove 2133, and the transition base 2216 is provided with an air connector 22161 for communicating an air inlet end of the 2131 with the rotating shaft 222. The surface of the transition seat 2216 is provided with an elastic glue layer to realize interference fit between the transition seat 2216 and the clamping groove 2133.

The plurality of suction cups 212 may form a plurality of suction points, thereby improving the stability of the sole on the contoured shoe mold 211. It is understood that the number of the suction cups 212 is not limited to four as illustrated in the present embodiment, but may be one, two, three, five, or more, and is adaptively changed according to the size of the sole and the requirement for the magnitude of the suction force.

Further, in the present embodiment, four air pipes (not shown) are disposed in the rotating shaft 222, and the air pipes are connected to the air pipes 2131 in a one-to-one correspondence manner. One air pipe is correspondingly connected with one vacuum generator. One suction cup 212 corresponds to one vacuum generator, so that the vacuum adsorption force provided by each suction cup 212 can be ensured, and the binding force between the profiling shoe mold 211 and the sole can be ensured to meet the requirement.

In addition, in order to avoid the entanglement among the air tubes due to the rotation of the rotary base 221, in the present embodiment, the rotary assembly 22 further includes: a rotary joint (not shown).
