DETAILED DESCRIPTION
[0024] See also Figure 1-7As shown, the technical solution adopted in this specific embodiment is: it comprises a tray 1, a transmission mechanism 4 is arranged on one side of the surface of the tray 1, a guide rail 5 is arranged on one side of the transmission mechanism 4, a fastening mechanism 2 is arranged on the guide rail 5, and the fastening mechanism 2 is in frictional contact with the transmission mechanism 4. In this embodiment, the driving of the fastening mechanism is realized by the friction between the transmission mechanism and the fastening mechanism. A blocking mechanism 3 is arranged on the bottom surface of the tray 1, and the blocking mechanism is used to accurately position the fastening mechanism to facilitate the next production process;
[0025] The fastening mechanism 2 includes a fixed panel 2-1 and a fixed bottom plate 2-2. The fixed bottom plate 2-2 is arranged at the bottom of the fixed panel 2-1. A fixed groove is opened in the middle of the fixed panel 2-1, and the fixed groove extends to the rear end of the fixed panel 2-1, presenting an open groove structure. Two fixed blocks 2-3 are symmetrically arranged on the fixed panel 2-1. An auxiliary baffle 2-5 is arranged at the rear end of the fixed panel 2-1. The auxiliary baffle 2-5 seals and constrains the fixed groove. In this embodiment, the fastening mechanism clamps and fixes the shoe last in multiple dimensions. First, an open fixed groove is set, and the shoe last can be pushed into the opening of the fixed groove without precise alignment, thereby improving the installation speed, and the connector of the shoe last shoe mouth is fixed in the fixed groove. Second, When the shoe last completely enters the fixing groove, the shoe mouth part is clamped and fixed by two fixing blocks. Thirdly, the auxiliary baffle 2-5 is rotated. One end of the auxiliary baffle 2-5 is a fixed end fixed by a fastening bolt 2-10, and the other end is provided with an arc-shaped locking mouth, and a positioning bolt 2-11 is provided at the corresponding position. After the auxiliary baffle 2-5 is rotated, the arc-shaped locking mouth is engaged with the positioning bolt, and the shoe last is limited and fixed from the end of the shoe last. Fourthly, an iron sheet 2-9 is provided in the fixing groove of the fixing panel 2-1. Since the connecting piece of the shoe last 6 is provided with a strong magnet, it is adsorbed with the iron sheet after being placed in the fixing groove. Therefore, the fastening mechanism fixes the shoe last from multiple directions and dimensions, ensuring that the shoe last is not easy to shake during the production process, thereby ensuring product quality.
[0026] More specifically, a positioning clamp plate 2-6 is provided at the front end of the fixed base plate 2-2, and a U-shaped groove is provided at the front end of the positioning clamp plate 2-6. The U-shaped groove is provided on the positioning clamp plate so as to cooperate with the blocking mechanism for precise positioning.
[0027] More specifically, four movable guide wheels 2-4 are arranged at the bottom of the fixed base plate 2-2, a V-shaped guide groove 2-41 is arranged in the middle of the movable guide wheel 2-4, and V-shaped guide edges 5-1 are arranged on both sides of the guide rail 5, and the guide edges 5-1 match the guide groove 2-41. Since the fastening mechanism moves by the friction force generated by the transmission mechanism, the V-shaped guide groove is matched with the V-shaped guide edge, which can ensure the limiting effect and minimize the friction, thereby ensuring the smooth movement of the fastening mechanism.
[0028] To be more specific, a friction plate 2-7 is provided at the bottom of the positioning clamp plate 2-6, and the friction plate 2-7 is connected to the positioning clamp plate 2-6 by bolts, and a spring 2-8 is provided on the bolts. In this embodiment, the friction plate is a rubber plate, and the fastening mechanism and the transmission mechanism are in contact with the belt through the friction plate. The spring can provide a certain expansion force to ensure that the friction plate is in close contact with the belt to obtain the maximum friction driving force.
[0029] More specifically, the blocking mechanism 3 also includes a cylinder 3-1, a push connecting rod 3-2, a positioning plate 3-3, and a connecting shaft 3-4. The piston rod of the cylinder 3-1 is movably connected to one end of the push connecting rod 3-2, and the other end of the push connecting rod 3-2 is connected to the connecting shaft 3-4. The bottom of the positioning plate 3-3 is connected to the connecting shaft 3-4. The upper and middle part of the positioning plate 3-3 passes through the empty groove in the middle of the fixed panel 2-1. The two ends of the connecting shaft 3-4 are connected to the mounting seat bearings arranged on both sides of the bottom of the tray 1. In this embodiment, The blocking mechanism is a connecting rod mechanism, and the end of the cylinder 3-1 is movably connected to a cylinder support plate 3-5. The top of the cylinder support plate 3-5 is fixed on the pallet 1. After the cylinder is started, the cylinder push rod drives the push rod to move, and drives the connecting shaft to rotate, so that the positioning plate rotates together and is stuck in the opening of the positioning clamping plate when rotating. Because the fastening mechanism stops when it is transmitted to the middle of the pallet, the belt is loose to a certain extent. When the positioning plate is stuck in the positioning clamping plate, it will drive the positioning clamping plate to move slightly and adjust to the middle position, thereby achieving precise positioning.
[0030] The working principle of the utility model is as follows: when the transmission mechanism 4 is not started, the shoe last 6 is first installed on the fastening mechanism 2, specifically, the connecting piece on the top of the shoe last is aligned with the opening of the fixing groove of the fixing panel 2-1 and pushed into the fixing groove. At this time, the connecting piece of the shoe last is deeply inserted into the fixing groove. Since the connecting piece is provided with a magnet, it is adsorbed with the iron sheet 2-9 after being placed in the fixing groove. At the same time, the shoe mouth of the shoe last 6 is clamped and fixed by the fixing block 2-3. When the shoe last 6 is completely pushed into the fixing groove, the rotating auxiliary baffle 2-5 is engaged with the positioning bolt 2-11, thereby limiting the shoe last 6 from the rear end. Fixed, at this time the installation and fastening of the shoe last 6 is completed, the whole process is simple and effective, and then the transmission mechanism 4 is started, and the fastening mechanism 2 is driven to move through the friction force with the friction plate 2-7. During the movement, the fastening mechanism 2 moves the guide wheel 2-4 to cooperate with the guide rail 5 to achieve smooth movement. When it moves to the middle of the tray 1, the transmission mechanism 4 is stopped, and the cylinder 3-1 is started to drive the positioning plate 3-3 to rotate. The positioning plate 3-3 is stuck in the U-shaped groove at the front end of the positioning splint 2-6, and the position of the fastening mechanism 2 will be fine-tuned to ensure that the shoe last 6 is in place at the designated position for subsequent production.
[0031] 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.
