DETAILED DESCRIPTION

[0024] See also Figure 1-6As shown, the technical solution adopted in this specific implementation is: it includes a tray 1, a blocking mechanism 2, and a clamping mechanism 3. The blocking mechanism 2 is movably arranged at the bottom of the tray 1, and the clamping mechanism 3 is movably arranged at the top of the tray 1. In this embodiment, the blocking mechanism is a connecting rod mechanism to position the clamping mechanism. A guide rail 5 is arranged at the top edge of the tray 1. The clamping mechanism moves on the guide rail and is positioned by the blocking mechanism after the shoe last is fixed. The blocking mechanism 2 includes a positioning plate 2-4, and the positioning plate 2-4 is movably arranged at the center of the empty slot in the middle of the tray 1. The positioning plate is the core positioning structure in the connecting rod mechanism. When the clamping mechanism is transmitted to the central area, the position of the clamping mechanism is adjusted and positioned by the positioning plate. The clamping mechanism 3 includes a support plate 3-1 and a positioning splint 3-2. The positioning splint 3-2 is arranged at the front end of the support plate 3-1 facing the side of the positioning plate 2-4. Four The shoe last is fixed to the shoe frame 3-1 by the guide rail 5 and the guide rails 5 are connected to the shoe frame 3-1 by the guide rails 5. The shoe last is fixed to the shoe frame 3-1 by the guide rails 5. The shoe last is fixed to the shoe frame 3-1 by the guide rails 5. The shoe last is fixed to the shoe frame 3-1 by the guide rails 5. The shoe last is fixed to the shoe frame 3-1 by the guide rails 5.

[0025] To be more specific, the blocking mechanism 2 also includes a cylinder 2-1, a pushing connecting rod 2-2, and a connecting shaft 2-3. The piston rod of the cylinder 2-1 is movably connected to one end of the pushing connecting rod 2-2, and the other end of the pushing connecting rod 2-2 is connected to the connecting shaft 2-3. The connecting shaft 2-3 is connected to the bottom of the positioning plate 2-4, and both ends of the connecting shaft 2-3 are connected to the mounting seat bearings arranged on both sides of the bottom of the tray 1. The blocking mechanism 2 also includes a cylinder stabilizing seat 2-5, and a support plate is arranged on the cylinder stabilizing seat 2-5 and is movably connected to the end of the cylinder 2-1. In this embodiment, the blocking mechanism is a movable connecting rod mechanism, and the end of the cylinder can rotate and move. When started, the cylinder push rod is pushed out, driving the pushing connecting rod to move, and further driving the connecting shaft to rotate, thereby driving the positioning plate to rotate, thereby positioning the clamping mechanism.

[0026] More specifically, a matching block 2-41 is provided on the top of the positioning plate 2-4, and the front end of the positioning clamp 3-2 is a U-shaped opening structure, and the opening shape matches the matching block 2-41. In this embodiment, the matching block is circular, and the optional matching block and the positioning plate are movably connected, which can better fine-tune the position of the clamping mechanism when in contact with the positioning clamp.

[0027] To be more specific, a conveying mechanism 4 is provided on the top of the tray 1 close to the guide rail 5, and the conveying mechanism 4 is located below the positioning clamp 3-2. In this embodiment, the conveying mechanism is a belt conveying mechanism. A clamping plate 3-5 is elastically connected to the bottom of the positioning clamp 3-2. The clamping plate 3-5 is in contact with the conveying mechanism 4. The clamping plate is made of materials such as rubber with high friction. The friction with the belt is increased by a spring. When the conveying mechanism is started, the clamping mechanism can be driven to move by friction.

[0028] More specifically, an adjustment groove is provided in the clamping block 3-3, an adjustment bolt 3-6 is arranged in the adjustment groove, and the adjustment bolt 3-6 is threadedly connected to the support plate 3-1. When debugging the equipment, the tightness of the shoe last connector can be adjusted by loosening the adjustment bolt, so that it can match shoe last connectors of different specifications.

[0029] More specifically, guide grooves are provided on both sides of the guide rail 5 to cooperate with the guide wheels 3-4. The cooperation between the guide grooves and the guide wheels can better limit the position of the guide wheels to prevent the clamping mechanism from shaking up and down.

[0030] More specifically, the inner shape of the clamping block 3 - 3 matches the shape of the shoe last connector 7 , and different clamping blocks and shoe last connectors are selected to cooperate according to production requirements to obtain the best fastening effect.

[0031] The working principle of the utility model is as follows: after the shoe last and the shoe last connector 7 are fastened by bolts, the fixing hole 7-1 on the shoe last connector 7 is aligned with the fixing pin 3-8 and placed between the two clamping blocks 3-3, the strong magnet 3-7 is attracted to the magnet arranged at the bottom of the shoe last connector 7-1, the clamping blocks 3-3 clamp the shoe last horizontally from both sides, the positioning pin 3-8 limits the shoe last longitudinally, the strong magnet 3-7 attracts the shoe last vertically, and the shoe last is fastened in multiple dimensions. After the shoe last is installed, the transmission mechanism 4 is started, and the clamping mechanism 3 is driven to move along the guide rail 5 by the friction between the transmission mechanism 4 and the pressing plate 3-5. After moving to the approximate center position, the conveying mechanism is stopped. At this time, the cylinder 2-1 is started to drive the positioning plate 2-4 to rotate and the matching block 2-41 to approach the positioning clamping plate 3-2, and the matching block 2-41 is inserted into the opening of the positioning clamping plate 3-2. At this time, since the conveying mechanism 4 has stopped and the conveying belt is in a slightly loose state, the clamping mechanism 3 will be located in a small range under the action of the matching block 2-41 and adjusted to the most central position. The conveying mechanism 4 is started again to tighten the clamping plate 3-5. With the cooperation of the guide wheel 3-4 and the guide rail 5, the clamping mechanism 3 is tightened in place. The entire positioning process is simple to operate and has a good fixing effect.

[0032] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: by adopting the method of strong magnetic adsorption and cooperating with the positioning shaft and the fixing block, the shoe last is clamped and fixed from multiple dimensions. It only needs to align the positioning hole with the positioning pin to adsorb and fix it. The installation and disassembly are relatively convenient. By arranging an auxiliary positioning plate at the front end of the support plate and cooperating with the movable blocking mechanism, precise positioning can be achieved, which greatly improves the production qualification rate and is beneficial to improving production efficiency.

[0033] The above description is only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
