Description

Technical Field

[0001] This utility model discloses a double-sided last pressing machine with controllable pressure, belonging to the technical field of shoemaking equipment. Background Technology

[0002] Double-sided lasting machines are crucial equipment in the shoemaking industry for shaping shoe soles. Shoe soles, fresh from the injection molding machine, are nearly 100 degrees Celsius and are larger in size, requiring a temperature-controlled shaping line. Although the temperature drops after this line, the size is still not standard, necessitating a second shaping process in the lasting machine to achieve the correct size. However, existing double-sided lasting machines suffer from the following key problems:

[0003] Traditional last-pressing machines mostly use cylinders as a power source. However, the output pressure of cylinders is easily affected by factors such as air source fluctuations and seal wear. Although cylinder drive provides pressure regulation to a certain extent, the adjustment accuracy is limited. Therefore, when dealing with shoe soles of different materials, it is difficult to adjust the pressure to a more suitable value. Moreover, whether the pressure needs to be adjusted also depends on the operator's experience and judgment. As a result, the processing efficiency will be reduced when processing different shoe soles. To solve this problem, a new solution is needed. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0018] A pressure-controlled double-sided lasting machine, such as Figures 1-3 As shown, the machine includes a body 1, with a pressing plate 2 in the middle of the body 1. An upper support frame 3 and a lower support frame 4 are provided on both sides of the pressing plate 2. The upper support frame 3 is equipped with an electrically controlled pressing component 5, and the lower support frame 4 is equipped with an electrically controlled pressing component 6. The electrically controlled pressing components 5 and 6 can press the sole and the mold onto the pressing plate 2, thereby pressing and shaping the sole. By using an electrically controlled drive instead of the traditional pneumatic drive, the distance traveled by the two pressing components can be precisely adjusted and controlled, and the adjustment is more controllable and convenient, improving the control accuracy and response speed.

[0019] The electrically controlled pressing assembly 5 includes a pressing plate 51 and an electrically controlled push rod 52. The electrically controlled push rod 52 is fixed on the upper support frame 3, with its output end facing the pressing plate 2. The pressing plate 51 is fixed on the output end of the electrically controlled push rod 52. The electrically controlled push rod 52 can be a planetary ball screw electric cylinder, which combines the advantages of ball screws and planetary gears, providing higher rigidity and greater load-bearing capacity. It also has a strong ability to precisely control the scaling stroke, making it suitable for this equipment. The pressing plate 51 is a flat pressing plate. Since the entire electrically controlled pressing assembly 5 is located above the pressing plate 2, when pressing the plate, simply place the mold at the corresponding position above the pressing plate 2, place the shoe sole on the mold, place the shoe last on the shoe sole, and then activate the electrically controlled push rod 52 to make the pressing plate 51 press down on the shoe last mold, thus completing the pressing and shaping of the plate.

[0020] The electrically controlled pressing assembly 26 includes a support plate 261 and an electrically controlled push rod 262. The electrically controlled push rod 262 is fixed on the lower support frame 4, with its output end facing the pressing plate 2. The support plate 261 is fixed on the output end of the electrically controlled push rod 262. The electrically controlled push rod 262 can also be a planetary ball screw electric cylinder. The support plate 261 is a grooved plate. Since the entire electrically controlled pressing assembly 26 is located below the pressing plate 2, when pressing the plate, simply place the mold inside the support plate 261, then place the shoe sole on the mold, then place the shoe last on the shoe sole, and then activate the electrically controlled push rod 262 to move the support plate 261, the shoe sole and the mold placed inside it upwards, and press them against the pressing plate 2 to complete the pressing and shaping.

[0021] Pressure detection components 7 and 8 are respectively installed on both sides of the pressing plate 2. The machine body 1 is equipped with a PLC control touch screen 9 for controlling the electric pressing components 5 and 6 and providing feedback on the pressure value. Through the detection of the two sets of pressure detection components 7 and 8, when the electric pressing components 5 and 6 are shaping the pressing plate, the PLC control touch screen 9 will display the current pressure value, which will facilitate subsequent adjustment operations.

[0022] The number and position of the pressure detection components 7 correspond to those of the electrically controlled top pressing components 5. The pressure detection components 7 include a support plate 71 and a pressure sensor 72. The pressure sensor 72 is located above the pressing plate 2, with its sensing end facing the top pressing plate 51. The support plate 71 is connected to the sensing end of the pressure sensor 72. The support plate 71 is aligned with the top pressing plate 51. During the pressing operation, the mold, sole, and last are no longer placed directly above the pressing plate 2, but are placed inside the support plate 71. When the top pressing plate 51 is pressed down, the pressure is transmitted from the support plate 71 to the pressure sensor 72, allowing the pressure sensor 72 to detect the current pressure value and transmit the value to the PLC control touch screen 9.

[0023] The number and position of the pressure detection components 28 correspond to those of the electrically controlled top pressing components 26. The pressure detection components 28 include a top pressing plate 281 and a pressure sensor 282. The pressure sensor 282 is located below the pressing plate 2, with its sensing end facing the support plate 261. The top pressing plate 281 is connected to the sensing end of the pressure sensor 282. The top pressing plate 281 and the support plate 261 are aligned. During the pressing operation, after the support plate 261 and the shoe sole and mold placed inside it move upward, it does not directly press against the pressing plate 2, but presses against the top pressing plate 281. This allows the pressure to be transmitted from the top pressing plate 281 to the pressure sensor 282, which detects the current pressure value and transmits the value to the PLC control touch screen 9.

[0024] Several air-cooled fans 10 are fixed inside the machine body 1. The air-cooled fans 10 are set on the upper and lower sides of the pressing plate 2. The number and position of the air-cooled fans 10 correspond to the electronically controlled pressing component 5 and the electronically controlled pressing component 6. The air-cooled fans 10 enable the soles in the pressing plate to cool down quickly, thereby improving the shaping efficiency.

[0025] The pressing machine of this application has multiple uses, two of which are described below;

[0026] Firstly, real-time control is achieved through the detected pressure values: During the operation of the pressure plate, the vertical pressure value is fed back in real time on the PLC control touch screen 9. The operator can adjust the equipment in real time based on the current vertical pressure value and the condition of the pressure plate. The advantage of this method is that manual control allows for detailed adjustments at any time, but it also relies heavily on the operator's experience and ability, making it suitable for customized production.

[0027] Secondly, automatic control is achieved through preset pressure values: Before pressing, the preset pressure values ​​and automation program are input into the PLC control touch screen 9, so that the PLC system can automatically operate the equipment according to the preset pressure values, so that the pressure can be maintained at the set value during the pressing process. The advantage of this method is that it achieves complete automation, does not rely on the operator's experience, and greatly improves production efficiency. However, it is more cumbersome when detailed adjustments are needed, and it is suitable for mass production.

[0028] While both methods have their advantages and disadvantages, they both achieve high-precision real-time monitoring and control of pressure during the lasting process by using electronic control components and pressure detection, combined with PLC control. This solves the problem of pressure instability caused by factors such as air source fluctuations and seal wear in the traditional cylinder-driven method, as well as the problem that the cylinder-driven method cannot automatically adjust pressure parameters according to the needs of different shoe sole materials. This effectively improves the working effect and efficiency of the lasting machine.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
