Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, and in particular to a pressing machine for shoemaking production with auxiliary limiting function. Background Technology

[0002] In the general shoe manufacturing process, pressing the sides of the shoe is an indispensable step to ensure a tight fit and shaping. This requires the use of pressing equipment. During operation, the shoe is first placed on the pressing machine. After starting the machine, the top limiting mechanism presses down on the shoe last placed inside the shoe to secure it. Then, the sides of the shoe are pressed. However, when pressing tall boots, due to their long shafts and soft material, the boot shafts cannot stand upright on their own after being placed on the pressing machine. Therefore, at the beginning of pressing, the boot shafts need to be hooked onto the telescopic cylinder of the top limiting mechanism. However, because the boot shafts are not fully restrained, they often collapse during the pressing process, affecting the pressing work and requiring improvement. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a shoe-making pressing machine with an auxiliary limiting function. The pressing machine includes a top limiting mechanism, which comprises a telescopic cylinder and an electrically operated telescopic pressure rod. The telescopic cylinder is equipped with an auxiliary limiting device for auxiliary limiting of the boot shaft. The auxiliary limiting device includes a mounting platform, a pair of control rods, a pair of transmission rod assemblies, a pair of auxiliary pressure plates, and a pair of mounting plates. The mounting platform is mounted on the electrically operated telescopic pressure rod. The pair of control rods are symmetrically arranged on the mounting platform. The telescopic cylinder has a pair of mounting grooves that match the pair of control rods. A pair of transmission channels communicating with the pair of mounting grooves are formed on the circumference of the telescopic cylinder. The pair of control rods are respectively disposed within the pair of mounting grooves and slidably connected to them. The pair of transmission rod assemblies are respectively disposed within the pair of transmission channels and movably connected to them. The pair of mounting plates are symmetrically arranged on the telescopic cylinder above the pair of transmission channels. One end of each pair of auxiliary pressure plates is rotatably connected to the mounting plates.

[0004] Using the above technical solution, when pressing the sole and upper of tall boots, after placing the boot on the pressing machine, the boot shaft is fitted onto the telescopic cylinder of the top limiting mechanism. Then, the equipment is started, and the electric telescopic pressure rod of the top limiting mechanism presses down to contact the shoe last inside the tall boot, limiting the overall position of the boot. As the electric telescopic pressure rod descends, it drives a pair of control rods to descend. The ends of the control rods are initially in contact with the ends of the transmission rod assembly, restricting the movement of the transmission rod assembly. The transmission rod assembly pushes open a pair of auxiliary pressure plates, keeping the pair of auxiliary pressure plates in an open state. After the control rods descend, their ends leave the transmission rod assembly, and the transmission rod assembly hangs freely away from the pair of auxiliary pressure plates. At this time, the auxiliary pressure plates that limit the transmission rod assembly also naturally hang down, pressing down the boot shaft fitted onto the telescopic cylinder, restricting the movement of the boot shaft, and ensuring that the boot shaft will not accidentally collapse and affect the pressing process.

[0005] A further feature of this invention is that each pair of transmission rods includes an end movable plate, a middle movable plate, and a transmission end rod that are rotatably connected in sequence. The end movable plate is rotatably connected to the two side walls of the transmission through groove. The shape and size of the transmission end rod match the mounting slide groove. The transmission end rod is disposed in the mounting slide groove and slides in cooperation with the mounting slide groove.

[0006] Using the above technical solution, since each pair of transmission rods includes an end movable plate, a middle movable plate, and a transmission end rod that are rotatably connected in sequence, the end movable plate is rotatably connected to the two side walls of the transmission through groove, the shape and size of the transmission end rod matches the mounting slide groove, the transmission end rod is set in the mounting slide groove and slides with the mounting slide groove, after the transmission end rod is pushed by the control rod, the end movable plate and the middle movable plate will bulge outward until the maximum stroke position, which can completely push open the pair of auxiliary pressure plates, making it convenient for the shoe sleeve to be fitted onto the telescopic cylinder.

[0007] A further feature of this invention is that a lifting block is provided in the mounting groove at a position that matches the transmission rod assembly.

[0008] By adopting the above technical solution, since a lifting block is provided in the mounting groove at the position that matches the transmission rod assembly, the situation where the lifting block in the mounting groove at the position that matches the transmission rod assembly bulges inward into the mounting groove, thus preventing the pair of auxiliary pressure plates from being opened, can be avoided.

[0009] A further feature of this invention is that each of the pair of auxiliary pressure plates is provided with a counterweight block at one end.

[0010] By adopting the above technical solution, since each of the pair of auxiliary pressure plates is provided with a counterweight block at one end, the limiting of the boot shaft is more secure. Attached Figure Description

Detailed Implementation

[0016] like Figure 1-4 As shown, a shoe-making pressing machine with auxiliary limiting function includes a pressing machine 2 with a top limiting mechanism 1. The top limiting mechanism includes a telescopic cylinder 3 and an electric telescopic pressure rod 4. The telescopic cylinder is provided with an auxiliary limiting device 5 for auxiliary limiting of the boot shaft. The auxiliary limiting device includes a mounting platform 6, a pair of control rods 7, a pair of transmission rod groups 8, a pair of auxiliary pressure plates 9, and a pair of mounting plates 10. The mounting platform is set on the electric telescopic pressure rod. The pair of control rods are symmetrically arranged on the mounting platform. The telescopic cylinder has a pair of mounting grooves 11 that match the pair of control rods. The circumference of the telescopic cylinder has a pair of transmission channels 12 that communicate with the pair of mounting grooves. The pair of control rods are respectively set in the pair of mounting grooves and slidably connected to the mounting grooves. The pair of transmission rod groups are respectively set in the pair of transmission channels and movably connected to the transmission channels. The pair of mounting plates are symmetrically arranged on the telescopic cylinder at a position above the pair of transmission channels. One end of each pair of auxiliary pressure plates is rotatably connected to the mounting plate.

[0017] When pressing the sole and upper of tall boots together, the boot is placed on the pressing machine, and then the boot shaft is fitted onto the telescopic cylinder of the top limiting mechanism. The machine is then started, and the electric telescopic pressure rod of the top limiting mechanism presses down to contact the shoe last inside the tall boot, limiting the overall position of the boot. As the electric telescopic pressure rod descends, it causes a pair of control rods to descend as well. Initially, the ends of the control rods are in contact with the ends of the transmission rod assembly, restricting the movement of the transmission rod assembly. The transmission rod assembly pushes open a pair of auxiliary pressure plates, keeping them in an open state. After the control rods descend, their ends leave the transmission rod assembly, allowing the transmission rod assembly to hang freely and away from the pair of auxiliary pressure plates. At this point, the auxiliary pressure plates that limit the transmission rod assembly also naturally hang down, pressing down on the boot shaft fitted onto the telescopic cylinder, restricting its movement, and ensuring that the boot shaft will not accidentally collapse and affect the pressing process.

[0018] Each pair of transmission rods includes an end movable plate 13, a middle movable plate 14, and a transmission end rod 15 that are rotatably connected in sequence. The end movable plate is rotatably connected to the two side walls of the transmission through groove. The shape and size of the transmission end rod match the mounting slide groove. The transmission end rod is set in the mounting slide groove and slides with the mounting slide groove.

[0019] Since each pair of transmission rod assemblies includes an end movable plate, a middle movable plate, and a transmission end rod that are rotatably connected in sequence, the end movable plate is rotatably connected to the two side walls of the transmission through groove, and the shape and size of the transmission end rod matches the mounting slide groove, the transmission end rod is set in the mounting slide groove and slides in cooperation with the mounting slide groove. After the transmission end rod is pushed by the control rod, the end movable plate and the middle movable plate will bulge outward until the position of the maximum stroke, which can completely push open the pair of auxiliary pressure plates, making it convenient for the shoe sleeve to be fitted onto the telescopic cylinder.

[0020] A lifting block 16 is provided in the mounting groove at a position that matches the transmission rod assembly.

[0021] Because a lifting block is provided in the mounting groove at a position that matches the transmission rod assembly, the situation where the lifting block in the mounting groove at the position that matches the transmission rod assembly bulges inward into the mounting groove, thus preventing the pair of auxiliary pressure plates from opening.

[0022] Each of the pair of auxiliary pressure plates is provided with a counterweight block 17 at one end.

[0023] Because each of the pair of auxiliary pressure plates is equipped with a counterweight block at one end, the positioning of the boot shaft is more secure.
