Description

Technical Field

[0001] This invention relates to the field of cutting technology, and more specifically to a cutting machine for the production of protective shoes. Background Technology

[0002] Shoe cutting machines are core equipment in shoemaking and leather processing, mainly used to cut materials into shoe parts of the required shape. The shortcomings of existing technology are that current cutting equipment typically cuts the raw material directly. When multiple layers of material are stacked from top to bottom to create a significant thickness, the cutting force between adjacent layers can cause relative slippage or displacement, making it difficult to ensure neat cut edges. Furthermore, the semi-mechanical, semi-manual method makes it difficult to guarantee the consistency and yield of finished products. Summary of the Invention

[0003] The purpose of this invention is to provide a cutting machine for the production of protective shoes, so as to overcome the above-mentioned shortcomings in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A cutting machine for producing protective shoes includes a frame, a conveying assembly disposed on one side of the upper end of the frame, and further includes: A cutting assembly is provided, located on the upper part of the frame and away from the conveying assembly. The cutting assembly includes a gantry frame, which is located on the upper part of the frame. A hydraulic rod is provided in the middle of the inner side of the gantry frame, and a cutting mechanism is provided at the lower end of the hydraulic rod. The cutting mechanism includes a mold. The hydraulic rod drives the mold to descend and cut the raw material. A pre-compression member is provided around the mold, and the lower end of the pre-compression member protrudes from the mold.

[0011] As described above, the cutting assembly also includes a support mechanism, which is located directly below the cutting mechanism. The support mechanism includes a lifting plate, which is slidably mounted on the frame. A damping rod is provided between the lifting plate and the frame.

[0016] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

They are only for the convenience of describing this invention and simplifying the description, and 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 this invention.

[0018] like Figures 1-5 As shown in the figure, an embodiment of the present invention provides a cutting machine for producing protective shoes, including a frame 1, a conveying assembly 4 disposed on one side of the upper end of the frame 1, and further including: A cutting assembly 3 is disposed on the upper end of the frame 1 and on the side away from the conveying assembly 4. The cutting assembly 3 includes a gantry frame 30, which is disposed on the upper end of the frame 1. A hydraulic rod 31 is disposed in the middle of the inner side of the gantry frame 30. A cutting mechanism 32 is disposed at the lower end of the hydraulic rod 31. The cutting mechanism 32 includes a mold 320. The hydraulic rod 31 drives the mold 320 to descend and cut the raw material. A pre-compression member 33 is disposed around the mold 320. The lower end of the pre-compression member 33 protrudes from the mold 320. As the hydraulic rod 31 drives the mold 320 to move downward, the pre-compression member 33 contacts the raw material earlier than the mold 320 and continuously compresses it until the mold 320 contacts the raw material for cutting.

[0019] In another embodiment of the present invention, a feeding assembly 2 is also included. The feeding assembly 2 includes a placement roller 20, which is rotatably disposed on the upper end of the frame 1. A material feeding frame 21 is also disposed on the upper end of the frame 1. Two fixed rollers 22 are rotatably disposed inside the material feeding frame 21. Each fixed roller 22 has a gear 23 at its end. The two gears 23 mesh with each other. At least one fixed roller 22 has a feeding motor 24 at one end. The feeding motor 24 is disposed on the upper end of the frame 1. A soft rubber layer 25 is disposed on the outer side of the fixed roller 22. The specific implementation method is as follows: Before cutting the raw material, the rolled raw material is manually placed on the frame 1 by the placement roller 20, and the free end of the rolled material passes through the feeding frame 21, so that the raw material is between two fixed rollers 22. Finally, the free end of the raw material is placed on the upper end of the conveying component 4 to ensure that the conveying component 4 can convey the raw material. At the same time, the feeding motor 24 drives the fixed roller 22 connected to it to rotate. The rotated fixed roller 22 drives the other fixed roller 22 to rotate synchronously and in the opposite direction by two meshing gears 23, so that the two fixed rollers 22 unwind and feed the raw material on the placement roller 20 during the rotation. In addition, the soft rubber layer 25 on the outside of the fixed roller 22 can produce appropriate deformation so as to realize the function of the fixed roller 22 rotating to convey raw materials of different thicknesses.

[0020] In another embodiment of the present invention, the conveying assembly 4 includes a conveyor belt 40, which is disposed on the upper end of the frame 1. A pressing mechanism 41 is disposed on the upper end of the conveyor belt 40. The pressing mechanism 41 is disposed on the upper end of the frame 1 via a linear drive member 42. A plurality of support rollers 43 are rotatably disposed on the frame 1. The support rollers 43 are disposed in the middle of the conveyor belt 40. The specific implementation method is as follows: The free end of the raw material is passed through the feeding frame 21, so that the raw material is between two fixed rollers 22. Then, the free end of the raw material is placed on the upper end of the conveyor belt 40. At this time, the pressing mechanism 41 presses and fixes the free end of the raw material to the upper surface of the conveyor belt 40. When the pressing mechanism 41 presses the free end of the raw material, the support roller 43 supports and limits the conveyor belt 40 to prevent the conveyor belt 40 from denting when the pressing mechanism 41 presses down on the free end of the raw material. After the raw material is pressed, the conveyor belt 40 starts to rotate and drives the raw material to move. During the process of the conveyor belt 40 driving the raw material to move, the linear drive component 42 drives the pressing mechanism 41 to move synchronously with the conveyor belt 40, so that the conveyor belt 40 and the pressing mechanism 41 pull the raw material to move synchronously with the conveyor belt 40. In addition, the conveyor belt 40 The pressing mechanism 41 drives the raw material to move intermittently. When the raw material stops moving, the hydraulic rod 31 drives the cutting mechanism 32 to descend vertically, causing the cutting mechanism 32 to drive multiple molds 320 to descend synchronously and cut the raw material. When the cutting mechanism 32 cuts the raw material through the molds 320, the hydraulic rod 31 drives the pre-compression component 33 to descend first and contact the raw material. When the molds 320 contact and cut the raw material, the pre-compression component 33 can press and fix the raw material. After the raw material is cut, the hydraulic rod 31 drives the molds 320 and the pre-compression component 33 to rise and move away from the raw material. At this time, the cut and shaped raw material is removed and collected manually. After the cut and shaped raw material is removed, the linear drive component 42 drives the pressing mechanism 41 and the conveyor belt 40 to move synchronously to pull the raw material. After the raw material moves, the cutting mechanism 32 cuts the raw material again.

[0021] In another embodiment of the present invention, the clamping mechanism 41 includes two mounting brackets 410, each of the linear drive members 42 is provided with a mounting bracket 410, each of the mounting brackets 410 is provided with a clamping cylinder 411, and a clamping plate 412 is provided between the extended ends of the two clamping cylinders 411. The specific implementation method is as follows: After the free end of the raw material is placed on the upper end of the conveyor belt 40 and close to the cutting mechanism 32, the pressing cylinder 411 drives the pressing plate 412 to descend, so that the lower end of the pressing plate 412 descends and adheres to the upper surface of the free end of the raw material. At this time, the pressing cylinder 411 drives the pressing plate 412 to continue to descend, so that the pressing plate 412 and the conveyor belt 40 clamp the raw material. While the pressing plate 412 descends and presses the raw material, the support roller 43 supports and limits the conveyor belt 40. After the raw material is clamped by the pressing plate 412 and the conveyor belt 40, the linear drive 42 drives the pressing cylinder 411 and the pressing plate 412 to move synchronously with the conveyor belt 40, so that the conveyor belt 40 and the pressing plate 412 pull the raw material to move synchronously. By controlling the start and stop of the linear drive 42 and the conveyor belt 40, the conveyor belt 40 and the pressing plate 412 can intermittently feed the raw material.

[0022] In another embodiment of the present invention, the cutting mechanism 32 includes a mounting plate 321. Two guide rods 322 are symmetrically arranged on the upper end of the mounting plate 321. The guide rods 322 are slidably arranged inside the gantry frame 30. A plurality of molds 320 are snap-fitted onto the lower end of the mounting plate 321. A clamping plate 323 is arranged on the side of the mold 320. The clamping plate 323 is slidably arranged on the lower end of the mounting plate 321. A plurality of clamping springs 324 are arranged between the clamping plate 323 and the mounting plate 321. The specific implementation method is as follows: When the extended end of the hydraulic rod 31 drives the mounting plate 321 to descend, the mounting plate 321 drives the two guide rods 322 on it to descend synchronously, so that the two guide rods 322 guide and limit the mounting plate 321 to prevent the mounting plate 321 from rotating during descent. Thus, when the hydraulic rod 31 drives the mounting plate 321 to descend vertically, the mounting plate 321 drives the multiple molds 320 at its lower end to descend synchronously, so that the descending molds 320 gradually contact and cut the raw material pulled by the pressing plate 412 and the conveyor belt 40, so that the molds 320 can cut and shape the raw material; in addition, when the cutting mechanism 32 is not working... During operation, by pulling the clamping plate 323, the clamping plate 323 compresses the clamping spring 324 and slides along the mounting plate 321, thereby releasing the clamping plate 323 from the clamping and fixing of the mold 320. At this time, the mold 320 can be removed from the mounting plate 321 and replaced. After the mold 320 is replaced, the clamping plate 323 is released, causing the clamping spring 324 to compress the clamping plate 323, causing the clamping plate 323 to move in the opposite direction along the mounting plate 321 so as to lock and fix the replaced mold 320 at the lower end of the mounting plate 321. In this way, by replacing the mold 320 of different specifications, the mounting plate 321 can cut and shape raw materials of different specifications, thereby reducing the production cost of protective shoes.

[0023] In another embodiment of the present invention, the pre-compression component 33 includes a plurality of pressure plates 330. A plurality of connecting posts 331 are uniformly arranged along the length of the upper end of the pressure plate 330. A sliding plate 332 is provided at the upper end of the connecting post 331. The sliding plate 332 and the connecting post 331 are both slidably disposed in the mounting plate 321. An adjusting plate 333 is provided above the sliding plate 332. The adjusting plate 333 is slidably disposed in the mounting plate 321. A plurality of adjusting springs 334 are provided between the adjusting plate 333 and the sliding plate 332. An adjusting screw 335 is rotatably disposed at the middle of the upper end of the adjusting plate 333. The adjusting screw 335 is disposed on the mounting plate 321 by means of threaded engagement. The specific implementation method is as follows: When the extended end of the hydraulic rod 31 drives the mold 320 to descend via the mounting plate 321, the mounting plate 321 first drives the pressure plate 330 to descend until it contacts the raw material. During the continuous descent of the mounting plate 321 driven by the extended end of the hydraulic rod 31, the pressure plate 330 drives the sliding plate 332 to move along the mounting plate 321 via the connecting column 331. At this time, the sliding plate 332 can squeeze the adjusting spring 334, so that the adjusting spring 334 squeezes the adjusting plate 333. In this way, the adjusting spring 334 can react on the sliding plate 332, so that the sliding plate 332... The moving plate 332 and the connecting column 331 apply pressure to the pressure plate 330, thereby pressing the material tightly. After the pressure plate 330 completely presses the material, the mounting plate 321 drives the mold 320 to continue to descend. At this time, the pressure plate 330 further compresses the adjusting spring 334 through the connecting column 331 and the sliding plate 332 until the lower end of the mold 320 contacts and cuts the material. During the material cutting process, the pressure plate 330 always maintains a pressing state on the material, reducing or even avoiding the movement of the material due to the compression of the mold 320, preventing the cut material from being misshapen, that is, in the liquid... When the pressure rod 31 drives the mold 320 to move downward, the pressure plate 330 passively descends synchronously with the mold 320, and contacts the raw material earlier than the mold 320 and continuously presses it down until the mold 320 contacts the raw material for cutting. Furthermore, by rotating the adjusting screw 335, the adjusting screw 335 drives the adjusting plate 333 to move along the mounting plate 321, thereby adjusting the position of the adjusting plate 333. This allows the adjusting plate 333 to adjust the preload of the adjusting spring 334, so that the pressure plate 330 can be adjusted in real time according to the specifications of the mold 320 and the thickness of the raw material. The clamping force of the raw material ensures that the pressure plate 330 clamps the raw material while preventing the adjusting spring 334 from being over-compressed. Thus, the pre-compression component 33 has three functions: First, before the die 320 cuts, the pre-compression component 33 first contacts and clamps the raw material to prevent the raw material from moving and deforming during cutting; Second, the pre-compression component 33 can make way during cutting to ensure that the die 320 can move a sufficient stroke to completely cut the raw material; Third, the adjusting screw 335 can enable the pre-compression component 33 to pre-compress raw materials of different thicknesses, improving the applicability of the equipment.

[0024] In another embodiment of the present invention, the lower end of the pressure plate 330 is provided with sharp teeth; The specific implementation method is as follows: When the extended end of the hydraulic rod 31 drives the pressure plate 330 to press the raw material through the mounting plate 321, the pressure plate 330 squeezes and limits the raw material through the sharp teeth provided at its lower end, ensuring that the raw material will not move when squeezed by the mold 320.

[0025] In another embodiment of the present invention, the cutting assembly 3 further includes a supporting mechanism 34, which is disposed directly below the cutting mechanism 32. The supporting mechanism 34 includes a lifting plate 340, which is slidably disposed on the frame 1. A damping rod 341 is disposed between the lifting plate 340 and the frame 1. An adjusting disc 342 is provided at the extended end of the damping rod 341 through a threaded engagement. The damping rod 341 adjusts the downward stroke of the lifting plate 340 through the adjusting disc 342. The specific implementation method is as follows: The lifting plate 340 is located directly below the mold 320 and inside the pressure plate 330. Thus, when the extended end of the hydraulic rod 31 drives the mounting plate 321 to descend, the mounting plate 321 drives the pressure plate 330 and the mold 320 to descend synchronously. The mounting plate 321 first presses and fixes the raw material onto the frame 1 via the pressure plate 330. When the extended end of the hydraulic rod 31 drives the mold 320 to continue descending via the mounting plate 321, the mold 320 descends and cuts the inner part of the area pressed by the pressure plate 330. While the mold 320 descends to cut the raw material, the mold 320 continuously squeezes the lifting plate 340 with the raw material, so that the lifting plate 340 cooperates with the mold 320. The raw material is cut into shape. After the mold 320 descends to cut the raw material, the mounting plate 321 drives the mold 320 to continue to descend. At this time, when the pressure of the mold 320 on the lifting plate 340 exceeds the pressure required to cut the raw material, the mold 320 can squeeze the lifting plate 340, causing the lifting plate 340 to squeeze the damping rod 341 and descend vertically along the frame 1, thereby allowing the lifting plate 340 to make way and avoid collision between the lifting plate 340 and the mold 320, which could cause damage to the mold 320. When the lifting plate 340 descends, the movement of the lifting plate 340 is adjusted by the adjusting disc 342 to prevent the cutting raw material on it from falling off due to excessive descent distance.

[0026] Working principle: Before cutting the raw material, the rolled material is manually placed on the frame 1 using the placement roller 20, and the free end of the rolled material passes through the feeding frame 21, so that the raw material is between two fixed rollers 22. Finally, the free end of the raw material is placed on the upper end of the conveying assembly 4 to ensure that the conveying assembly 4 can convey the raw material. At the same time, the feeding motor 24 drives the fixed roller 22 connected to it to rotate. The rotated fixed roller 22 drives the other fixed roller 22 to rotate synchronously and in the opposite direction through two meshing gears 23, so that the two fixed rollers 22 are in a position where... During rotation, the raw material on the placement roller 20 is unwound and fed. Furthermore, the soft rubber layer 25 on the outer side of the fixed roller 22 can undergo appropriate deformation to enable the fixed roller 22 to rotate and convey raw materials of different thicknesses. The free end of the raw material is passed through the feeding frame 21, placing it between the two fixed rollers 22. Then, the free end of the raw material is placed on the upper end of the conveyor belt 40. At this time, the pressing mechanism 41 presses and fixes the free end of the raw material to the upper surface of the conveyor belt 40. When the pressing mechanism 41 presses the free end of the raw material, the support roller 43 supports and limits the conveyor belt 40, preventing... When the pressing mechanism 41 presses down on the free end of the raw material, the conveyor belt 40 becomes concave. After the raw material is pressed, the conveyor belt 40 starts to rotate and moves the raw material. During the process of the conveyor belt 40 moving the raw material, the linear drive 42 drives the pressing mechanism 41 to move synchronously with the conveyor belt 40, so that the conveyor belt 40 and the pressing mechanism 41 pull the raw material to move synchronously with the conveyor belt 40. In addition, the conveyor belt 40 and the pressing mechanism 41 move the raw material intermittently. When the raw material stops moving, the hydraulic rod 31 drives the cutting mechanism 32 to descend vertically, so that the cutting mechanism 32 drives multiple molds 320 to descend synchronously and... When the cutting mechanism 32 cuts the raw material through the mold 320, the hydraulic rod 31 drives the pre-compression component 33 to descend and contact the raw material. When the mold 320 contacts and cuts the raw material, the pre-compression component 33 can press and fix the raw material. After the raw material is cut, the hydraulic rod 31 drives the mold 320 and the pre-compression component 33 to rise and move away from the raw material. At this time, the cut and shaped raw material is removed and collected manually. After the cut and shaped raw material is removed, the linear drive component 42 drives the pressing mechanism 41 and the conveyor belt 40 to move synchronously to pull the raw material. After the raw material moves, the cutting mechanism 32 cuts the raw material again.After the free end of the raw material is placed on the upper end of the conveyor belt 40 and close to the cutting mechanism 32, the pressing cylinder 411 drives the pressing plate 412 to descend, so that the lower end of the pressing plate 412 descends and fits against the upper surface of the free end of the raw material. At this time, the pressing cylinder 411 drives the pressing plate 412 to continue to descend, so that the pressing plate 412 and the conveyor belt 40 clamp the raw material. While the pressing plate 412 descends and presses the raw material, the support roller 43 supports and limits the conveyor belt 40. After the raw material is clamped by the pressing plate 412 and the conveyor belt 40, the linear drive 42 drives the pressing cylinder 411 and the pressing plate 412 to move synchronously with the conveyor belt 40, so that the conveyor belt 40 and the pressing plate 412 pull the raw material to move synchronously. By controlling the start and stop of the linear drive 42 and the conveyor belt 40, the conveyor belt 40 and the pressing plate 412 can intermittently feed the raw material. When the extended end of the hydraulic rod 31 drives the mounting plate 321 to descend, the mounting plate 321 drives the two guide rods 322 on it to descend synchronously. This allows the two guide rods 322 to guide and limit the mounting plate 321, preventing it from rotating during descent. As the hydraulic rod 31 drives the mounting plate 321 to descend vertically, the mounting plate 321 drives the multiple molds 320 at its lower end to descend synchronously. This allows the descending molds 320 to gradually contact and cut the raw material that has been pulled and fed by the clamping plate 412 and the conveyor belt 40, so that the molds 320 can cut and shape the raw material. Furthermore, when the cutting mechanism 32 is not working, by pulling the clamping plate 323, the clamping plate 323 compresses the clamping spring 324 and slides along the mounting plate 321, thereby allowing the clamping plate 323 to... 3. Release the clamping and fixing of mold 320. At this time, mold 320 can be removed from mounting plate 321 and replaced. After mold 320 is replaced, release clamping plate 323, so that clamping spring 324 squeezes clamping plate 323, so that clamping plate 323 moves in the opposite direction along mounting plate 321 to lock and fix the replaced mold 320 to the lower end of mounting plate 321. In this way, by replacing molds 320 of different specifications, mounting plate 321 can cut and shape raw materials of different specifications, thereby reducing the production cost of protective shoes. When the extended end of hydraulic rod 31 drives mold 320 to descend through mounting plate 321, mounting plate 321 first drives pressure plate 330 to descend until it contacts the raw material. During the continuous descent of mounting plate 321 driven by extended end of hydraulic rod 31, pressure plate 330... The connecting column 331 drives the sliding plate 332 to move along the mounting plate 321. At this time, the sliding plate 332 can compress the adjusting spring 334, causing the adjusting spring 334 to compress the adjusting plate 333. In this way, the adjusting spring 334 can react on the sliding plate 332, so that the sliding plate 332 and the connecting column 331 apply pressure to the pressure plate 330, thereby making the pressure plate 330 press the raw material. After the pressure plate 330 has fully pressed the raw material, the mounting plate 321 drives the mold 320 to continue to descend. At this time, the pressure plate 330 further compresses the adjusting spring 334 through the connecting column 331 and the sliding plate 332 until the lower end of the mold 320 contacts and cuts the raw material. During the raw material cutting process, the pressure plate 330 always maintains a pressing state on the raw material, reducing or even avoiding the raw material being cut by the mold 320. The pressure plate 330 moves under pressure to prevent the cut material from becoming misshapen. Furthermore, by rotating the adjusting screw 335, the adjusting screw 335 moves the adjusting plate 333 along the mounting plate 321, thereby adjusting the position of the adjusting plate 333. This allows the adjusting plate 333 to adjust the preload of the adjusting spring 334, so that the pressure plate 330 can be adjusted in real time according to the specifications of the mold 320 and the thickness of the material, ensuring that the pressure plate 330 presses the material firmly while preventing excessive compression of the adjusting spring 334. When the extended end of the hydraulic rod 31 drives the pressure plate 330 to press the material via the mounting plate 321, the pressure plate 330 uses its lower end's pointed teeth to squeeze and limit the material, ensuring that the material does not move when squeezed by the mold 320. The lifting plate 340 is positioned directly below the mold 320 and inside the pressure plate 330. Thus, when the extended end of the hydraulic rod 31 lowers the mounting plate 321, the mounting plate 321 causes the pressure plate 330 and mold 320 to descend synchronously. The mounting plate 321 first presses and fixes the raw material onto the frame 1 via the pressure plate 330. As the extended end of the hydraulic rod 31 continues to lower the mold 320 via the mounting plate 321, the mold 320 cuts the material within the area pressed by the pressure plate 330. While the mold 320 cuts the raw material, it continuously presses against the lifting plate 340 with the material, allowing the lifting plate 340 to cooperate with the mold 320 in cutting the material. In addition to the cutting process, after the mold 320 descends to cut the raw material, the mounting plate 321 drives the mold 320 to continue descending. At this time, when the pressure of the mold 320 on the lifting plate 340 exceeds the pressure required to cut the raw material, the mold 320 can squeeze the lifting plate 340, causing the lifting plate 340 to squeeze the damping rod 341 and descend vertically along the frame 1, thereby allowing the lifting plate 340 to make way and avoiding collision between the lifting plate 340 and the mold 320, which could cause damage to the mold 320. When the lifting plate 340 descends, the movement of the lifting plate 340 is adjusted by the adjusting disc 342 to prevent the cutting raw material on it from falling off due to excessive descent distance.
