Description
Technical Field
[0001] The utility model relates to the technical field of leather cutting, in particular to a multi-layer leather equidistant cutting device for leather products which is easy to transmit. Background Art
[0002] Multi-layer leather cutting involves the precise and efficient cutting of multiple leather areas of varying thickness and texture in a single process. This is typically accomplished using advanced CNC machine tools, robotic arms, and other equipment. Compared to traditional single-layer leather cutting, multi-layer leather cutting offers higher production efficiency, reduced scrap rates, improved cutting quality, and a wider range of applications.
[0003] However, in the current existing technology, when leather is cut at a fixed distance, the length of the leather extended is usually cut at a fixed distance according to the conveying time interval during feeding. However, during the conveying process of the leather inside the cutting equipment, the conveying speed will change due to the change of the motor output power, which will affect the accuracy of the fixed distance cutting and reduce the cutting quality.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the embodiments of the present invention. Example
[0020] See also Figure 1-4 The utility model provides a technical solution: a multi-layer leather equidistant cutting device for leather products that is easy to transmit, comprising a cutting machine 1, a cutting table 2 is provided on the top of the cutting machine 1, an auxiliary component for assisting in spacing when cutting the leather is provided inside the cutting machine 1, the auxiliary component comprising a through slot 3 arranged on one side of the cutting machine 1, a conveyor belt 4 and a support block 5 are provided inside the through slot 3, the conveyor belt 4 circulates and transmits the leather in the cutting machine 1, the support block 5 can support the angle of the conveyor belt 4, the inner wall of the conveyor belt 4 is provided with a rack 401, the rack 401 can be engaged with the gear inside the cutting machine 1, and the conveyor belt 4 can be driven to transport by the motor-driven gear rotation. Both sides of the outer wall of the support block 5 are provided with hole slots 6, which can locate the position and angle of the latch gear 7 and provide a contraction space for the latch gear 7. When the conveyor belt 4 is transported, the rack 401 on the inner wall will mesh with the latch gear 7 and convey the leather through the conveyor belt 4. The belt 4 moves to match the angle of the rack 401 and the tooth 7 so that the tooth 7 retracts into the slot 6. A spring 602 and a tooth 7 are provided inside the two slots 6. The spring 602 is used to support the tooth 7 and push it out of the slot 6 so that it engages with the rack 401. Infrared sensors 601 are provided on both sides of the inner walls of the two slots 6. The infrared sensors 601 can detect when the tooth 7 retracts. When it is detected that the tooth 7 has retracted a specified number of times, a signal is sent and the electromagnet 801 is controlled to operate through the PLC controller, and the gear motor is controlled to turn off to stop the conveyor belt 4. A cavity 8 is provided inside the slot 6. In the normal state, the push rod 9 is accommodated. An electromagnet 801 and a push rod 9 are provided inside the cavity 8. When the electromagnet 801 is driven, a magnetic pole is generated to repel the magnetic block 901, thereby pushing the push rod 9 out of the cavity 8 and extending into the slot 6 to abut against the tooth 7 to push it out of the slot 6. A magnetic block 901 is provided at one end of the push rod 9. The main control center can position the transmission distance of the conveyor belt 4 according to the distance the leather needs to be cut (the transmission distance of the conveyor belt 4 can be calculated by the number of times the rack 401 abuts against the tooth 7 when the conveyor belt 4 is conveying, causing the tooth 7 to contract), and the conveyor belt 4 will stop for positioning after it drives the leather to move a specified distance. A baffle can be installed in the conveying trough of the cutting machine 1 to prevent the leather from moving due to inertia when the conveyor belt 4 stops.
[0021] In this embodiment, all electrical components are controlled by conventional controllers.
[0022] For example, please refer to Figure 1-4The support block 5 is integrally formed with the inner wall of the through slot 3, the conveyor belt 4 is sleeved on the outer wall of the support block 5, and a gear is installed inside the through slot 3 and is located inside the conveyor belt 4 and meshed with the rack 401 inside the conveyor belt 4, the rack 401 is connected to the inner wall of the conveyor belt 4 by bolts, the hole slots 6 on both sides of the outer wall of the support block 5 are connected to the conveyor belt 4, one end of the latch 7 is located in the hole slot 6, and is slidably connected to the inner wall of the hole slot 6 through a slide rail, and the other end extends from the hole slot 6 to the conveyor belt 4 The inner wall rack 401 is engaged, the spring 602 is located in the hole slot 6, and both ends are connected to the inner wall of the hole slot 6 and the tooth 7 by welding, the infrared sensor 601 is connected to the hole slot 6 by bolts, and the infrared sensor 601 is electrically connected to the tooth 7, the cavity 8 is communicated with the hole slot 6, the electromagnet 801 is connected to the inner wall of the cavity 8 by bolts, the electromagnet 801 is magnetically connected to the magnetic block 901, and the push rod 9 is located in the cavity 8 and is slidably connected to the inner wall of the cavity 8 through a slide rail. When in use, first place one end of the leather on the conveyor belt 4 and place it in front of the cutting table 2, then control the moving distance of the conveyor belt 4 according to the required cutting length (calculate the moving distance of the conveyor belt 4 by the number of times the tooth 7 contracts), then drive the conveyor belt 4 in the cutting machine 1 through the motor and gear to drive the leather through the cutting table 2, while the conveyor belt 4 is conveying, the rack 401 on the inner wall abuts against the tooth 7 when passing through the tooth 7 and squeezes the tooth 7 to contract into the slot 6, and the infrared sensor 601 detects when the tooth 7 contracts and stores the number of contraction data. When the conveyor belt 4 moves the specified distance (when the number of times the tooth 7 contracts reaches the set value), a signal is sent through the PLC controller to control the electromagnet 801 to run and control the motor and gear to stop. The electromagnet 801 repels the magnetic block 901, pushing the push rod 9 to extend into the slot 6 and abut against the tooth 7 so that it engages and locks with the rack 401, and at the same time controls the cutting table 2 to cut the leather. After cutting is completed, the PLC controller controls the reset and the cycle.

While the conveyor belt 4 is conveying, the rack 401 on the inner wall abuts against the latch teeth 7 when passing through the latch teeth 7 and squeezes the latch teeth 7 to shrink into the hole groove 6. When the latch teeth 7 shrink, it is detected by the infrared sensor 601 and the contraction number data is stored. When the conveyor belt 4 moves the specified distance (when the number of times the latch teeth 7 shrinks reaches the set value), a signal is sent through the PLC controller to control the electromagnet 801 to run and control the motor and gear to stop. The electromagnet 801 repels the magnetic block 901, pushing the push rod 9 to extend into the hole groove 6 and abut against the latch teeth 7 so that it engages and locks with the rack 401, and at the same time controls the cutting table 2 to cut the leather. After the cutting is completed, the PLC controller controls the reset and the cycle. The utility model realizes setting the transmission distance of leather driven by the conveyor belt, and stops the machine after transmitting the specified distance, performs auxiliary positioning for the fixed-distance cutting of leather, and improves the accuracy of the fixed-distance cutting of leather in conjunction with the conveying time.
