Technical Field
[0001] The utility model relates to the technical field of dynamic leather shoe processing equipment, in particular to a high-precision shaping device for leather shoe uppers. Background Art
[0002] Leather shoes are a type of shoe that people often wear. The upper of leather shoes is usually made of leather material, hence the name. In the process of leather shoe processing, the upper needs to be shaped first, and then the upper is connected to the sole. Leather material has good flexibility, so leather shoes are prone to rebound after shaping, resulting in poor shaping effect. The working principle of the existing leather shoe upper shaping machine is: since the upper needs to be processed into an arc that matches the instep, the leather material needs to be placed on a shaping base, and then pressed down by a pressing plate. The shape of the middle pressure plate is adapted to the arc shape of the upper to be formed. The existing leather shoe upper forming device has the following defects: first, when the pressure plate is pressed down and contacts the forming base, it is easy to cause wear of the upper, affecting subsequent processing; second, the existing forming device has a poor forming effect on the leather, and the leather is easy to rebound after forming; third, the placement of the leather during forming is usually determined based on the staff's own experience, and the leather forming position is prone to deviation, which causes the leather to need to be ironed and re-formed, affecting work efficiency. Summary of the invention
[0003] In order to solve the above problems, the utility model provides a high-precision shaping device for leather shoe uppers, which can improve the shaping accuracy of leather, improve the shaping effect of leather, and avoid leather wear during the shaping process.
[0004] The technical solution of the utility model is as follows: a high-precision shaping device for leather shoe uppers, comprising an equipment base, a shaping base connected to the equipment base, a sliding base slidably connected to the equipment base, a pressing plate fixedly connected to the sliding base, a hydraulic cylinder for driving the pressing plate to move in a vertical direction, a first supporting base connected to the equipment base, a second supporting base connected to the equipment base, a connecting cloth connected between the first supporting base and the second supporting base, and a controller, wherein the connecting cloth has a certain elasticity, the first supporting base and the second supporting base are symmetrically arranged on the left and right sides of the shaping base, the pressing plate is located directly above the shaping base, the connecting cloth is connected between the gap between the first supporting base and the second supporting base, the shaping base is provided with a first curved surface, the pressing plate is provided with a second curved surface, the first curved surface and the second curved surface are respectively adapted to the shape and size of the instep of the shoe upper to be processed and shaped, and the controller is electrically connected to the hydraulic cylinder.
[0005] By adopting the above technical scheme, first, the staff places the leather to be processed on the connecting cloth, and then controls the hydraulic cylinder through the controller to drive the sliding base to move vertically downward. Since the connecting cloth has a certain elasticity, the pressing plate will press down the leather to be processed and the connecting part together. Since the molding base is provided with a first curved surface, the pressing plate is provided with a second curved surface, and the first curved surface and the second curved surface are respectively adapted to the shape and size of the instep of the shoe upper to be processed and formed, therefore, the leather will be pressed into the shape of the instep of the shoe upper to be processed and formed, and due to the barrier effect of the connecting cloth, the leather can be prevented from being directly worn between the pressing plate and the molding base. When the molding work is completed, the controller controls the hydraulic cylinder to drive the sliding base to move vertically upward. After the connecting cloth loses pressure, the connecting cloth will quickly reset due to the elastic effect of the connecting cloth itself, and at the same time, the shaped shoe upper will be brought out to complete the discharging.
[0006] Further configuration of the utility model: the shaping base is also provided with a first shaping plate fixedly connected to the shaping base, a second shaping plate fixedly connected to the shaping base, a first connecting pipe connected to the first shaping plate, a second connecting pipe connected to the second shaping plate, and a steam generator connected to the first connecting pipe and the second connecting pipe, the shape enclosed by the first shaping plate and the second shaping plate is adapted to the shape and size of the first arc-shaped surface, and the controller is electrically connected to the steam generator.
[0007] By adopting the above technical solution, since the shape enclosed by the first shaping plate and the second shaping plate is adapted to the shape and size of the first curved surface, when the controller controls the hydraulic cylinder to drive the sliding base to press down, the controller simultaneously controls the steam generator to operate, and the steam generator outputs steam through the first connecting pipe and the second connecting pipe respectively. When the leather to be processed is pressed between the first shaping plate, the second shaping plate and the pressing plate, the shaping effect of the leather can be further improved through the action of steam.
[0008] The utility model is further configured as follows: a laser indicator is provided on the equipment base, the number of laser beams emitted by the laser indicator is greater than or equal to 2, and the positions of the laser beams emitted by the laser indicator correspond to the central axis of the shaping base respectively.
[0009] By adopting the above technical scheme, since the position of the laser beam emitted by the laser indicator corresponds to the central axis of the shaping base, when the staff places the leather to be processed, the two ends of the leather are respectively aligned with the position of the laser beam emitted by the laser indicator, and the position of the entire leather is ensured to be accurate through two-point positioning. Then, the hydraulic cylinder is controlled by the controller to drive the sliding base to move vertically downward to complete the shaping of the leather. This can further improve the shaping accuracy and the shaping effect.
[0010] Further configuration of the utility model: a first limit baffle and a second limit baffle are respectively provided on the first support base and the second support base, a first limit groove and a second limit groove are respectively provided on the first limit baffle and the second limit baffle, a shape enclosed by the first limit groove and the second limit groove is adapted to the shape and size of the end of the leather to be processed, the first limit baffle and the second limit baffle are symmetrically arranged with the central axis of the shaping base as the axis center, when the leather to be processed is placed on the first support base and the second support base and the ends of the leather are respectively in contact with the first limit baffle and the second limit baffle, the pressing plate presses down to shape the leather into the shape of the shoe upper to be processed.
[0011] By adopting the above technical scheme, since the shape enclosed by the first limiting groove and the second limiting groove is adapted to the shape and size of the end portion of the leather to be processed, when the leather to be processed is placed on the first supporting base and the second supporting base and the ends of the leather are respectively in contact with the first limiting baffle and the second limiting baffle, the hydraulic cylinder is controlled by the controller to drive the sliding base to move vertically downward, so that the shape of the leather formed is the standard shape of the shoe upper that needs to be processed and formed. This allows the staff to place the leather in the correct processing position more accurately and conveniently, thereby further ensuring the shaping accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] like Figure 1-2As shown, a high-precision shaping device for leather shoe uppers comprises an equipment base 1, a shaping base 2 connected to the equipment base 1, a sliding base 3 slidably connected to the equipment base 1, a pressing plate 4 fixedly connected to the sliding base 3, a hydraulic cylinder 5 for driving the pressing plate 4 to move in a vertical direction, a first supporting base 6 connected to the equipment base 1, a second supporting base 7 connected to the equipment base 1, a connecting cloth 8 connected between the first supporting base 6 and the second supporting base 7, and a controller 9, wherein the connecting cloth 8 has a certain elasticity. The first supporting base 6 and the second supporting base 7 are symmetrically arranged on the left and right sides of the shaping base 2, the pressing plate 4 is located directly above the shaping base 2, the connecting cloth 8 is connected to the gap between the first supporting base 6 and the second supporting base 7, the shaping base 2 is provided with a first curved surface 10, the pressing plate 4 is provided with a second curved surface 11, the first curved surface 10 and the second curved surface 11 are respectively adapted to the shape and size of the instep of the shoe upper to be processed and formed, and the controller 9 is electrically connected to the hydraulic cylinder 5.
[0016] First, the staff places the leather to be processed on the connecting cloth 8, and then controls the hydraulic cylinder 5 through the controller 9 to drive the sliding base 3 to move vertically downward. Since the connecting cloth 8 has a certain elasticity, the pressing plate 4 will press the leather to be processed and the connecting part together. Since the shaping base 2 is provided with a first curved surface 10, the pressing plate 4 is provided with a second curved surface 11, and the first curved surface 10 and the second curved surface 11 are respectively adapted to the shape and size of the instep of the shoe upper to be processed and formed, the leather will be pressed into the instep shape of the shoe upper to be processed and formed, and due to the barrier effect of the connecting cloth 8, the leather can be prevented from being directly worn between the pressing plate 4 and the shaping base 2. When the shaping work is completed, the controller 9 controls the hydraulic cylinder 5 to drive the sliding base 3 to move vertically upward. After the connecting cloth 8 loses pressure, due to the elastic effect of the connecting cloth 8 itself, the connecting cloth 8 will quickly reset, and at the same time, the shaped shoe upper will be brought out to complete the discharging.
[0017] The shaping base 2 is also provided with a first shaping plate 12 fixedly connected to the shaping base 2, a second shaping plate 13 fixedly connected to the shaping base 2, a first connecting pipe 14 connected to the first shaping plate 12, a second connecting pipe 15 connected to the second shaping plate 13, and a steam generator 16 connected to the first connecting pipe 14 and the second connecting pipe 15. The shape enclosed by the first shaping plate 12 and the second shaping plate 13 is adapted to the shape and size of the first curved surface 10, and the controller 9 is electrically connected to the steam generator 16.
[0018] Since the shape enclosed by the first shaping plate 12 and the second shaping plate 13 is adapted to the shape and size of the first curved surface 10, when the controller 9 controls the hydraulic cylinder 5 to drive the sliding base 3 to press down, the controller 9 simultaneously controls the steam generator 16 to work, and the steam generator 16 outputs steam through the first connecting pipe 14 and the second connecting pipe 15 respectively. When the leather to be processed is pressed between the first shaping plate 12, the second shaping plate 13 and the pressing plate 4, the shaping effect of the leather can be further improved through the action of steam.
[0019] The equipment base 1 is provided with a laser pointer 17 . The number of laser beams emitted by the laser pointer 17 is greater than or equal to 2. The positions of the laser beams emitted by the laser pointer 17 correspond to the central axis of the shaping base 2 .
[0020] Since the position of the laser beam emitted by the laser indicator 17 corresponds to the central axis of the shaping base 2, when the staff places the leather to be processed, the two ends of the leather are respectively aligned with the position of the laser beam emitted by the laser indicator 17, and the two-point positioning is used to ensure that the position of the entire leather is accurate. Then, the controller 9 controls the hydraulic cylinder 5 to drive the sliding base 3 to move vertically downward to complete the shaping of the leather. This can further improve the shaping accuracy and the shaping effect.
[0021] The first support base 6 and the second support base 7 are respectively provided with a first limit baffle 18 and a second limit baffle 19, and the first limit baffle 18 and the second limit baffle 19 are respectively provided with a first limit groove 20 and a second limit groove 21. The shape enclosed by the first limit groove 20 and the second limit groove 21 is adapted to the shape and size of the end of the leather to be processed, and the first limit baffle 18 and the second limit baffle 19 are symmetrically arranged with the central axis of the shaping base 2 as the axis. When the leather to be processed is placed on the first support base 6 and the second support base 7 and the ends of the leather are respectively in contact with the first limit baffle 18 and the second limit baffle 19, the pressing plate 4 presses down to shape the leather into the shape of the upper to be processed.
[0022] Since the shape enclosed by the first limiting groove 20 and the second limiting groove 21 is compatible with the shape and size of the end of the leather to be processed, when the leather to be processed is placed on the first supporting base 6 and the second supporting base 7 and the ends of the leather are respectively in contact with the first limiting baffle 18 and the second limiting baffle 19, the hydraulic cylinder 5 is controlled by the controller 9 to drive the sliding base 3 to move vertically downward, so that the shape of the leather is formed into the standard shape of the shoe upper that needs to be processed and formed. This allows the staff to place the leather in the correct processing position more accurately and conveniently, thereby further ensuring the shaping accuracy.
