Description

Technical Field

[0001] This invention relates to the field of cutting equipment technology, and in particular to an automatic feeding and cutting machine for shoe soles. Background Technology

[0002] The automatic shoe sole feeding and cutting machine is an intelligent punching and cutting equipment used for automatic feeding of shoe soles and other parts. It is designed to improve the efficiency of shoe production. It mainly consists of a frame, feeding mechanism, cutting mechanism and control center. During operation, the feeding traction system can accurately feed the roll or sheet material into the cutting area. The cutting mechanism is hydraulically or mechanically driven, and the die is driven by high tonnage pressure to punch and form the material. Nowadays, high-end models are generally equipped with microcomputer or vision recognition system, which can not only realize digital control of cutting pressure and stroke, but also automatically identify materials and optimize layout to achieve the most efficient material utilization.

[0003] Therefore, automatic sole feeding and cutting machines have become key equipment in modern shoe factories, especially in the manufacture of sports shoes, and are widely used in industries such as leather and packaging that require high-precision, large-volume cutting of non-metallic materials.

[0004] Existing cutting machines require periodic stops to complete the cutting process, resulting in low cutting efficiency. Summary of the Invention

The tension control system is mounted on the frame between the shoe sole sheet feeding device and the sheet tail material recycling device. The adaptive extrusion system is mounted on the frame and below the stamping power system. The adaptive extrusion system includes several adaptive extrusion devices rotatably mounted on the frame. These adaptive extrusion devices are adapted to the transverse punching system, which is slidably mounted on the output end of the stamping power system. The sliding direction is parallel to the feeding direction of the feeding traction system. The stamping power system periodically presses down on the transverse blanking system. The stamping power system includes a stamping frame, a stamping plate, a stamping cylinder, and a stamping return spring. The stamping frame is mounted on the machine frame. The stamping plate is slidably mounted on the stamping frame. The stamping cylinder is mounted on the stamping frame and is connected to the stamping plate in a transmission manner. The two ends of the stamping return spring press against the upper side of the machine frame and the lower side of the stamping plate, respectively. The transverse blanking system includes a transverse blanking block and a transverse blanking die. The transverse blanking block is mounted at the bottom of the stamping power system. The transverse blanking die is slidably mounted on the transverse blanking block. A blanking transverse return spring is provided between the transverse blanking block and the transverse blanking die. A permanent magnet is provided on the transverse blanking die to attract the transverse blanking block.

[0008] Preferably, the sole sheet supply device includes a sheet supply motor and a sheet supply roller, the sheet supply roller is rotatably mounted on the frame, the sheet supply motor is mounted on the frame, and the sheet supply roller is drivenly connected to the sheet supply motor.

[0009] Preferably, the feeding traction system includes a traction pretensioning frame, a traction pretensioning cylinder, a pretensioning reference plate, a traction motor, a traction active roller, and a traction passive roller. The pretensioning reference plate slides along the traction pretensioning frame. The traction pretensioning cylinder is mounted on the traction pretensioning frame and is drivenly connected to the pretensioning reference plate. The traction active roller is rotatably mounted on the frame. The traction motor is mounted on the frame and is drivenly connected to the traction active roller. The traction passive roller is rotatably mounted on the lower side of the pretensioning reference plate. The traction passive roller is arranged opposite to the traction active roller.

[0010] Preferably, the sheet material recycling device includes a sheet recycling motor and a sheet recycling roller. The sheet recycling roller is rotatably mounted on the frame, the sheet recycling motor is mounted on the frame, and the sheet recycling roller is drivenly connected to the sheet recycling motor.

[0011] Preferably, the tension control system includes a tension control frame, a tension control slider, and a tension control roller. The tension control roller is slidably mounted on the tension control frame via the tension control slider, and the tension control roller is rotatably mounted on the tension control slider.

[0012] Preferably, the adaptive extrusion device includes an adaptive extrusion roller, an adaptive extrusion slider, and an adaptive extrusion spring. The adaptive extrusion slider is slidably mounted on the frame, the adaptive extrusion roller is rotatably mounted on the adaptive extrusion slider, and the two ends of the adaptive extrusion spring press against the frame and the adaptive extrusion slider, respectively.

[0013] The beneficial effects of this invention are:

[0014] The sole sheet feeding device, feeding traction system, stamping power system, and sheet tail material recycling device are sequentially installed on the frame to supply rubber sheet raw materials. The tension control system is installed on the frame between the sole sheet feeding device and the sheet tail material recycling device to control the tension of the rubber sheet raw materials. The adaptive extrusion system is installed on the frame and below the stamping power system to push the rubber sheet raw materials to the transverse punching system to ensure that the rubber sheet material is cut.

[0015] The adaptive extrusion system includes several adaptive extrusion devices rotatably mounted on the frame. These devices are adapted to a transverse cutting system, which is slidably mounted at the output end of the press power system. The sliding direction of the transverse cutting system is parallel to the feeding direction of the feeding traction system, enabling cutting of the rubber sheet material during transport. This results in high cutting efficiency. The press power system periodically presses down on the transverse cutting system, thus periodically pressing the rubber sheet material towards the adaptive extrusion system. The adaptive extrusion system supports the rubber sheet material. After the transverse cutting system presses down on the rubber sheet material, it moves laterally along with the material, achieving cutting. Subsequently, the press power system rises, pressing down on the transverse cutting system to reset it. Due to the rising and falling process of the press power system, the transverse cutting system achieves continuous cutting, allowing for continuous transport of the rubber sheet material and improving production efficiency.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figure 1 — Figure 4 As shown, this embodiment provides an automatic shoe sole feeding and cutting machine, including a shoe sole sheet supply device 1, a stamping power system 2, a feeding traction system 3, a frame 4, a sheet tail material recycling device 5, a tension control system 6, a transverse punching system 7, and an adaptive extrusion system 8. The shoe sole sheet supply device 1, the feeding traction system 3, the stamping power system 2, and the sheet tail material recycling device 5 are sequentially installed on the frame 4 to supply rubber sheet raw materials. The tension control system 6 is installed on the frame 4 between the shoe sole sheet supply device 1 and the sheet tail material recycling device 5 to control the tension of the rubber sheet raw materials. The adaptive extrusion system 8 is installed on the frame 4 and is located below the stamping power system 2. It pushes the rubber sheet raw materials to the transverse punching system 7 to ensure that the rubber sheet raw materials are cut.

[0031] Specifically, the adaptive extrusion system 8 includes several adaptive extrusion devices rotatably mounted on the frame 4. The adaptive extrusion devices are adapted to the transverse cutting system 7, which is slidably mounted on the output end of the stamping power system 2. The sliding direction of the transverse cutting system 7 is parallel to the feeding direction of the feeding traction system 3, thereby realizing the cutting of rubber sheet raw materials during the conveying process. The stamping power system 2 periodically presses down on the transverse cutting system 7, thereby periodically pressing the rubber sheet raw materials towards the adaptive extrusion system 8. The adaptive extrusion system 8 supports the rubber sheet raw materials. After the transverse cutting system 7 presses down on the rubber sheet raw materials, it moves laterally along with the transverse movement of the rubber sheet raw materials, thereby realizing the cutting of the rubber sheet raw materials. Subsequently, the stamping power system 2 rises, and the transverse cutting system 7 is reset. Due to the rising and falling process of the stamping power system 2, the transverse cutting system 7 achieves continuous cutting, which enables the continuous conveying of rubber sheet raw materials and improves production efficiency.

[0032] Specifically, the shoe sole sheet supply device 1 includes a sheet supply motor and a sheet supply roller. The sheet supply roller is rotatably mounted on the frame 4, and the sheet supply motor is mounted on the frame 4. The sheet supply roller and the sheet supply motor are connected in a drive connection to realize the supply of rubber sheet raw materials.

[0033] Specifically, the stamping power system 2 includes a stamping frame 21, a stamping plate 22, a stamping cylinder 23, and a stamping return spring 24. The stamping frame 21 is mounted on the machine frame 4. The stamping plate 22 is mounted on the stamping frame 21 in a lifting and sliding manner. The stamping cylinder 23 is mounted on the stamping frame 21 and is connected to the stamping plate 22 in a transmission manner. The two ends of the stamping return spring 24 press against the upper side of the machine frame 4 and the lower side of the stamping plate 22, respectively, to realize the lifting and lowering of the transverse blanking system 7.

[0034] Specifically, the feeding traction system 3 includes a traction pretensioning frame 31, a traction pretensioning cylinder, a pretensioning reference plate 32, a traction motor 33, a traction active roller 34, and a traction passive roller 35. The pretensioning reference plate 32 slides along the traction pretensioning frame 31. The traction pretensioning cylinder is mounted on the traction pretensioning frame 31 and is connected to the pretensioning reference plate 32. The traction active roller 34 is rotatably mounted on the frame 4. The traction motor 33 is mounted on the frame 4 and is connected to the traction active roller 34. The traction passive roller 35 is rotatably mounted on the lower side of the pretensioning reference plate 32. The traction passive roller 35 is arranged opposite to the traction active roller 34. The traction pretensioning cylinder drives the traction passive roller 35 to roll in contact with the traction active roller 34, thereby realizing the conveying of rubber sheet raw materials under the drive of the traction motor 33.

[0035] Specifically, the sheet material recycling device 5 includes a sheet material recycling motor and a sheet material recycling roller. The sheet material recycling roller is rotatably mounted on the frame 4, and the sheet material recycling motor is mounted on the frame 4. The sheet material recycling roller and the sheet material recycling motor are connected in a drive connection to realize the recycling of the waste material.

[0036] Specifically, the tension control system 6 includes a tension control frame 61, a tension control slider 62, and a tension control roller 63. The tension control roller 63 is slidably mounted on the tension control frame 61 via the tension control slider 62. The tension control roller 63 is rotatably mounted on the tension control slider 62. Under its own action and gravity, the tension control roller 63 tensions the rubber sheet material, thereby maintaining the conveying tension of the rubber sheet material.

[0037] Specifically, the transverse cutting system 7 includes a transverse cutting block 71 and a transverse cutting die 72. The transverse cutting block 71 is installed at the bottom of the stamping power system 2, and the transverse cutting die 72 is slidably installed on the bottom of the transverse cutting block 71 via a dovetail joint. To enable the transverse cutting die 72 to return to its original position, a transverse cutting return spring 73 is provided between the transverse cutting block 71 and the transverse cutting die 72. To ensure that the horizontal position of the transverse cutting die 72 is determined at the beginning of cutting, a permanent magnet 74 is provided on the transverse cutting die 72 to attract the transverse cutting block 71. The working principle of the permanent magnet 74 is that when the stamping power system 2 lifts the transverse cutting system 7 away from the rubber sheet material, the transverse cutting return spring 73... The transverse cutting die 72 resets and eventually moves towards the position of the transverse cutting die 72 when the transverse cutting reset spring 73 is in a free state. Under the action of its own inertia, the transverse cutting die 72 continues to slide, while the permanent magnet 74 stops the transverse cutting die 72 and attracts the transverse cutting block 71. The permanent magnet 74 limits the extreme position of the transverse cutting die 72's reset sliding and maintains the extreme position of the transverse cutting die 72, which facilitates the adjustment of the conveying speed of the rubber sheet material. This makes the horizontal position of the transverse cutting die 72 after reset match the next cutting position after the rubber sheet material is conveyed, thereby maintaining cutting during the conveying process of the rubber sheet material and improving cutting efficiency.

[0038] Specifically, the adaptive extrusion device includes an adaptive extrusion roller 81, an adaptive extrusion slider 82, and an adaptive extrusion spring 83. The adaptive extrusion slider 82 is slidably mounted on the frame 4, the adaptive extrusion roller 81 is rotatably mounted on the adaptive extrusion slider 82, and the two ends of the adaptive extrusion spring 83 press on the frame 4 and the adaptive extrusion slider 82 respectively, thereby applying an upward adaptive pressing force to the rubber sheet material to ensure that the rubber sheet material is cut along the contour of the transverse punching die 72.
