Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, specifically to a rapid cutting machine for shoe linings. Background Technology

[0002] Shoe lining cutting machines are mainly used in the production workshops of footwear manufacturing enterprises. They can cut various types of shoes, such as sports shoes, leather shoes, and cloth shoes, using methods including vibrating knife cutting, laser cutting, water jet cutting, and stamping cutting.

[0003] Existing shoe lining cutting machines utilize a stamping cutting method that allows for rapid stamping and cutting of shoe linings using a die. However, when cutting thicker or harder materials, the inherent limitations of this method mean that the pressure and shearing force applied by the cutting tools cannot completely overcome the physical properties of the material, leading to incomplete cutting. This not only severely impacts the production quality and efficiency of shoe linings and increases the cost and time of subsequent manual processing, but also potentially wastes materials. Furthermore, after cutting, the cut material is prone to getting stuck in the die due to the combined effects of friction between the material and the die, material deformation, and die structure design during the stamping cutting process. The material stuck in the die is difficult to remove quickly, further reducing production efficiency. Utility Model Content

[0004] In view of the problems existing in the current shoe lining quick cutting machine, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a quick shoe lining cutting machine, which solves the problem that shoe lining cutting machines may not cut completely when dealing with thicker or harder materials, and that the cut material is easy to get stuck in the mold.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rapid shoe lining cutting machine includes a chamber, a first hydraulic rod fixedly connected to the top of the chamber, one end of the first hydraulic rod passing through the top of the chamber and fixedly connected to a sliding connecting seat, a sliding sleeve slidably connected to the outer wall of the sliding connecting seat, a buffer reset mechanism provided between the sliding connecting seat and the sliding sleeve, and a pneumatic hammer fixedly connected to the inner side wall of the sliding connecting seat, the pneumatic hammer corresponding to the position of the sliding sleeve.

[0008] The bottom of the sliding sleeve is fixedly connected to a mounting base, and a stamping die is inserted into the bottom of the mounting base. A limiting mechanism is provided between the mounting base and the stamping die. A sealing tube is fixedly connected inside the cavity of the mounting base. A connection port is opened at the top of the stamping die, and the sealing tube is inserted into the connection port. Airflow chambers are provided inside both the mounting base and the stamping die. Multiple exhaust and material discharge ports are opened at the bottom of the stamping die. An infrared preheating device is fixedly connected inside one end of the cavity of the sleeve. A cutting and placing tray is fixedly connected inside the cavity of the sleeve through a driving mechanism.

[0009] Preferably, the buffer reset mechanism includes a slide rod, a sliding sleeve, and a buffer damper. The slide rod is fixedly connected to both ends of the cavity of the sliding sleeve. The slide sleeve is slidably connected to the wall of both ends of the slide rod. The side wall of the sliding sleeve is fixedly connected to the side wall of the sliding connecting seat. A buffer damper is fixedly connected between the top of both ends of the cavity of the sliding sleeve and the top of both sliding sleeves.

[0010] Preferably, the limiting mechanism includes a mounting plate, a mounting slot, a limiting plate, a limiting threaded opening, and a limiting bolt. The two end side walls of the stamping die are fixedly connected to the mounting plate. The two end side walls of the mounting base are provided with mounting slots and fixedly connected to the limiting plates. The two end mounting plates are inserted into the mounting slots. The two end mounting plates and the limiting plates are provided with corresponding limiting threaded openings and threadedly connected to the limiting bolts.

[0011] Preferably, the driving mechanism includes a first electric push rod, a sliding opening, and a supporting slide plate. The first electric push rod is fixedly connected to the side wall of the compartment. A sliding opening is provided at the top of one end of the compartment, and a supporting slide plate is slidably connected thereto. One end of the first electric push rod is fixedly connected to the side wall of the supporting slide plate, and the top of the supporting slide plate is fixedly connected to the bottom of the cutting and placing tray.

[0012] Furthermore, the infrared preheating device includes a second electric push rod, the other end of which is fixedly connected to an infrared preheating lamp assembly.

[0013] Preferably, an air source assembly is fixedly connected to one end of the top of the chamber, and the two output ends of the air source assembly are fixedly connected to the input ends of the pneumatic hammer and the mounting base, respectively.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model utilizes the synergistic effect of a pneumatic hammer and an infrared preheating device to effectively overcome the problem of cutting thick and hard materials. When cutting thick and hard shoe lining materials, the pneumatic hammer works when the stamping die is close to the material, applying additional impact force to enhance the cutting force and avoid incomplete cutting. The infrared preheating device can soften the material, reduce its hardness and toughness, making the stamping die cutting easier, ensuring cutting quality and precision, and meeting the cutting needs of diverse materials.

[0016] 2. This utility model utilizes an airflow cavity and an exhaust / discharge port located within the mounting base and the stamping die, in conjunction with a buffer reset mechanism, to achieve efficient automatic material removal. After cutting, gas is introduced into the airflow cavity, and the gas is discharged at high speed from the exhaust / discharge port, blowing off the material stuck in the stamping die. The buffer reset mechanism buffers the impact force during cutting and drives the stamping die to reset quickly after cutting. The vibration during the reset process, combined with the airflow discharging function, further improves the discharging effect, reduces manual intervention, and increases production efficiency.

[0017] 3. This utility model utilizes a limiting mechanism to achieve rapid installation and disassembly of the stamping die through the engagement of the mounting plate with the mounting bayonet and the threaded connection of the limiting bolt. This facilitates the replacement of different models of die. The drive mechanism uses the first electric push rod to push the support slide plate to slide in the sliding opening, thereby moving the cutting and placing tray. This facilitates loading and unloading operations, simplifies the workflow, reduces labor intensity, and improves the practicality and flexibility of the equipment. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model discloses a rapid cutting machine for shoe linings.

[0026] This utility model provides, for example Figure 1-3 The shoe lining quick cutting machine shown includes a chamber 1. A first hydraulic rod 2 is fixedly connected to the top of the chamber 1. One end of the first hydraulic rod 2 passes through the top of the chamber 1 and is fixedly connected to a sliding connecting seat 3. A sliding sleeve 4 is slidably connected to the outer wall of the sliding connecting seat 3. A buffer reset mechanism is provided between the sliding connecting seat 3 and the sliding sleeve 4. A pneumatic hammer 5 is fixedly connected to the inner side wall of the sliding connecting seat 3. The pneumatic hammer 5 corresponds to the position of the sliding sleeve 4.

[0027] A mounting base 6 is fixedly connected to the bottom of the sliding sleeve 4. A stamping die 7 is inserted into the bottom of the mounting base 6. A limiting mechanism is provided between the mounting base 6 and the stamping die 7. A sealing tube 8 is fixedly connected inside the cavity of the mounting base 6. A connecting port 9 is opened on the top of the stamping die 7. The sealing tube 8 is inserted into the connecting port 9. An airflow cavity 10 is provided inside the cavities of both the mounting base 6 and the stamping die 7. Multiple exhaust and unloading ports 11 are opened at the bottom of the stamping die 7. An infrared preheating device 12 is fixedly connected inside one end of the cavity of the sleeve 1. A cutting and placing tray 13 is fixedly connected inside the cavity of the sleeve 1 through a drive mechanism. When cutting thicker or harder shoe lining materials, the first hydraulic rod 2 drives the sliding connecting seat 3 and the sliding sleeve 4 downwards, bringing the stamping die 7 closer to the material to be cut. At this time, the pneumatic hammer 5 operates, applying additional impact force to the sliding sleeve 4. This impact force is transmitted to the stamping die 7 through the mounting seat 6, significantly increasing the cutting force of the stamping die 7. This effectively solves the problem of incomplete cutting caused by materials that are too thick or too hard, ensuring the cutting quality of the shoe lining. The infrared preheating device 12 can preheat the shoe lining material to be cut. For thicker or harder materials, preheating can... To soften the material and reduce its hardness and toughness, making it easier for the stamping die 7 to cut, airflow chambers 10 are provided in both the mounting base 6 and the stamping die 7. Multiple exhaust and ejection ports 11 are also provided at the bottom of the stamping die 7. After the cutting action is completed, gas can be introduced into the airflow chambers 10, and the gas is discharged at high speed from the exhaust and ejection ports 11, forming a strong airflow. This airflow can blow away the material stuck in the stamping die 7, preventing the material from getting stuck in the die. The buffer reset mechanism can buffer the cutting process and quickly reset the stamping die 7 after cutting. During the reset process, the slight vibration of the stamping die 7, combined with the airflow unloading function, can more effectively separate the material stuck in the die, further improving the unloading effect. The set limiting mechanism facilitates the quick installation of the stamping die 7 and makes it easy to disassemble and replace it with different models of stamping die 7. The set driving mechanism drives the cutting placement tray 13 to move, facilitating loading and unloading operations. This solves the problem of incomplete cutting when the shoe lining cutting machine is used with thicker or harder materials, and the problem of the cut material easily getting stuck in the die.

[0028] To provide guiding assistance and buffer reset assistance for the stamping die 7, such as Figure 2As shown, the buffer reset mechanism includes a slide rod 14, a sliding sleeve 15, and a buffer damper 16. The slide rod 14 is fixedly connected to both ends of the cavity of the sliding sleeve 4. Sliding sleeves 15 are slidably connected to the walls of both ends of the slide rod 14. The side walls of the sliding sleeves 15 are fixedly connected to the side walls of the sliding connecting seat 3. Buffer dampers 16 are fixedly connected between the tops of both ends of the cavity of the sliding sleeve 4 and the tops of the sliding sleeves 15. The buffer dampers 16 effectively buffer the impact force generated when the stamping die 7 performs the cutting action, causing the first hydraulic rod 2 to drive the sliding connecting seat 3 and the sliding sleeve 4 to move downwards. When the pneumatic hammer 5 works to push the sliding sleeve 4 downwards, the sliding sleeve 15 slides on the slide rod 14, and the buffer damper 16 is compressed, absorbing the impact energy. To prevent the impact force from being directly transmitted to other parts of the equipment, the risk of equipment damage due to impact is reduced, and the service life of the equipment is extended. After the impact force disappears, the buffer damper 16 can quickly return to its original state, driving the sliding sleeve 15 to slide upward on the sliding rod 14, thereby enabling the sliding sleeve 4 and the stamping die 7 to quickly reset. This allows the cutting machine to perform the next cutting action in a short time, improving cutting efficiency and meeting the needs of large-scale production. The cooperation of the sliding rod 14 and the sliding sleeve 15 provides a stable guiding effect for the relative movement of the sliding connecting seat 3 and the sliding sleeve 4, ensuring the vertical movement of the stamping die 7 during the cutting process, avoiding the stamping die 7 from deflection or shaking during the movement, and improving the cutting accuracy and quality.

[0029] To facilitate the quick installation and disassembly of the stamping die 7 for use with different models, such as Figure 2 and 3 As shown, the limiting mechanism includes a mounting plate 17, a mounting slot 18, a limiting plate 19, a limiting threaded port 20, and a limiting bolt 21. The mounting plates 17 are fixedly connected to the side walls of both ends of the stamping die 7. The mounting slots 18 are opened on the side walls of both ends of the mounting base 6, and the limiting plates 19 are fixedly connected to them. The mounting plates 17 at both ends are inserted into the mounting slots 18. The mounting plates 17 at both ends and the limiting plates 19 at both ends have corresponding limiting threaded ports 20, and the limiting bolts 21 are threadedly connected to them. By using the limiting mechanism composed of the mounting plates 17, mounting slots 18, limiting plates 19, limiting threaded ports 20, and limiting bolts 21, the mounting plates 17 at both ends are engaged and positioned with the corresponding mounting slots 18, and then the limiting bolts 21 at both ends are threadedly connected to the corresponding limiting threaded ports 20. This allows for quick installation between the mounting base 6 and the stamping die 7, and facilitates quick disassembly and replacement of different models of stamping dies 7 by rotating and removing the limiting bolts 21.

[0030] To facilitate the movement of the cutting and placing tray 13 for loading and unloading materials, such as Figure 2As shown, the driving mechanism includes a first electric push rod 22, a sliding opening 23, and a support slide plate 24. The first electric push rod 22 is fixedly connected to the side wall of the chamber 1. A sliding opening 23 is opened at the top of one end of the chamber 1, and the support slide plate 24 is slidably connected thereto. One end of the first electric push rod 22 is fixedly connected to the side wall of the support slide plate 24. The top of the support slide plate 24 is fixedly connected to the bottom of the cutting and placing tray 13. By using the driving mechanism composed of the first electric push rod 22, the sliding opening 23, and the support slide plate 24, the first electric push rod 22 pushes the support slide plate 24 to slide in the sliding opening 23, thereby driving the cutting and placing tray 13 at the top to move, so as to facilitate the loading and unloading of materials after it is moved out of the chamber 1.

[0031] To preheat harder or thicker materials to facilitate subsequent stamping and cutting, such as Figure 2 As shown, the infrared preheating device 12 includes a second electric push rod 25, and an infrared preheating lamp assembly 26 is fixedly connected to the other end of the second electric push rod 25. The infrared preheating device 12, which consists of the second electric push rod 25 and the infrared preheating lamp assembly 26, can preheat harder or thicker materials, which is convenient for subsequent stamping and cutting work.

[0032] To provide an air source for the pneumatic hammer 5 and the mounting base 6, such as Figure 1 and 2 As shown, an air source assembly 27 is fixedly connected to one end of the top of the chamber 1. The two output ends of the air source assembly 27 are fixedly connected to the input ends of the pneumatic hammer 5 and the mounting base 6, respectively. The air source assembly 27 is used to provide air to the pneumatic hammer 5 and the mounting base 6.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
