[0002] In existing curtain airbags, protective airbags, and generator interfaces of OPWs, high-strength braided air ducts are added to avoid the impact of extremely high air pressure on the airbag during detonation, and the added air ducts play a buffering role. There are four existing cutting devices: blade cutting, hot melt cutting, laser cutting, and ultrasonic cutting. However, in the case of blade cutting, the weft yarns at both ends of the braided air duct are prone to falling off, affecting the performance of the braided air duct. In the existing technologies of hot melt cutting, laser cutting, and ultrasonic cutting, unilateral cutting is used, resulting in easy adhesion of the cut ends of the air ducts at both ends, affecting assembly. In addition, the existing cutting devices have a low degree of automation, resulting in low cutting efficiency. Summary of the Utility Model

Specific embodiments

[0023] Combined with Figures 1 to 3 As shown, this embodiment provides a cutting device for a braided air duct, including: a front conveying device 1, a rear conveying device 2, a cutting device 3, a flattening device 4, and a stacking device 6. Among them, the front conveying device 1 is adapted to convey the braided air duct to the rear conveying device 2, and the rear conveying device 2 is used to pull the braided air duct to a preset cutting length and then cut it through the cutting device 3 arranged between the front conveying device 1 and the rear conveying device 2; the cutting device 3 includes a laser head 31, a rotating device 32, and a cutting protection device 33. Among them, a cutting space adapted for the braided air duct to pass through is formed in the rotating device 32, the laser head 31 is connected to the rotating device 32, and the rotating device 32 is adapted to drive the laser head 31 to rotate around the outer circumference of the braided air duct to cut the braided air duct, and the cutting protection device 33 is sleeved outside the rotating device 32 to prevent laser leakage; the cut braided air duct is adapted to be conveyed to the flattening device 4 for flattening, and a clamping device 5 is arranged on the flattening device 4 to carry the flattened braided air duct into the stacking device 6 for stacking. In this embodiment, a control system is further included, and coordinated control is performed through the control system.

[0024] Combined with Figure 1 And Figure 3 As shown, the front conveying device 1 and the rear conveying device 2 are distributed along the same straight line, and the cutting device 3 is arranged at the connection of the front conveying device 1 and the rear conveying device 2. Specifically, both the front conveying device 1 and the rear conveying device 2 include a telescopic component and a linear motion mechanism. The telescopic component is adapted to expand the braided air duct from the inside to the outside to fix the braided air duct, and the linear motion mechanism is adapted to drive the telescopic component to move to convey the braided air duct sleeved on the telescopic component to the rear conveying device 2. The linear motion mechanism can adopt devices such as a linear motor or a ball screw pair. By fixing the braided air duct by expanding it from the inside, the outside of the braided air duct can be prevented from being damaged, and at the same time, after the braided air duct is expanded, the problem of adhesion at the cut can be prevented during cutting.

[0025] In one embodiment, the telescopic assembly includes a heat dissipation support sheet 11 and a contraction and expansion device 12, and a plurality of the heat dissipation support sheets 11 are mounted on the contraction and expansion device 12, and the contraction and expansion device 12 is suitable for driving the heat dissipation support sheet 11 to expand so as to stretch the braided air duct sleeved on the heat dissipation support sheet 11, so as to fix the braided air duct on the telescopic assembly. Here, the number of the heat dissipation support sheets 11 is 6-12, and the heat dissipation support sheets 11 are distributed in a circumference, and the contraction and expansion device 12 is suitable for driving the heat dissipation support sheets 11 to stretch along the diameter direction. The heat dissipation support sheet 11 adopts a metal sheet with good heat dissipation performance, and the contraction and expansion device 12 adopts an existing annular contraction and expansion structure. The contraction and expansion device 12 can drive the heat dissipation sheet to shrink inward or expand outward. When shrinking inward, the circular diameter formed by the annularly arranged heat dissipation support sheets 11 is reduced, thereby canceling the supporting effect on the braided air duct. When expanding outward, the circular diameter formed by the annularly arranged heat dissipation support sheets 11 is expanded, thereby stretching the inside of the braided air duct outward to fix the braided air duct on the telescopic assembly. It should be noted that when the braided airway tube is sleeved on the front conveying device 1, a space for the rear conveying device 2 to extend into needs to be reserved at the sleeve end. After the front conveying device 1 has conveyed the braided airway tube to the right position, the telescopic component of the rear conveying device 2 extends into the reserved section of the braided airway tube and expands outward to fix the braided airway tube. At this time, the front conveying device 1 contracts to cancel the fixation of the braided airway tube, and then the braided catheter is pulled to the cutting length by the rear conveying device 2 and the cutting device 3 is driven to cut; at this time, the telescopic component of the front conveying device 1 returns along the inside of the braided airway tube under the drive of the linear motion mechanism, and after the rear conveying device 2 conveys the cut braided catheter to the flattening device 4, a new section of the braided airway tube is conveyed to the rear conveying device 2. This alternating process can improve the conveying efficiency.

[0026] Combination Figure 2 As shown, the cutting device 3 is arranged at the connection between the front conveying device 1 and the rear conveying device 2. The cutting device 3 includes a laser head 31, a rotating device 32, and a cutting protection device 33. The laser head 31 is arranged in the rotating device 32, and the laser direction is toward the center of the rotating device 32; the rotating device 32 is provided with a cutting space suitable for the braided air duct to pass through, and the front conveying device 1 on one side conveys the braided air duct to the cutting space, and then the braided air duct is conveyed along the cutting space through the rear conveying device 2 on the other side. The cutting protection device 33 is arranged on the outside of the rotating device 32 to prevent the laser emitted by the laser head 31 from leaking out and causing harm to the operator, thereby improving the safety of the work. During operation, the rotating device 32 drives the laser head 31 to rotate around the outside of the braided air duct for one circle, and the laser emitted by the laser head 31 can cut off the entire braided air duct.

[0027] Combined Figure 1 As shown, the flattening device 4 includes upper and lower flattening rubber wheels, which are adapted to flatten the braided air duct when the braided air duct passes through the gap between the upper and lower flattening rubber wheels. Preferably, a clamping device 5 is provided on the flattening device 4 to transport the flattened braided air duct into the stacking device 6 for stacking. At the same time, a counting device is provided on the clamping device 5 to count the number of cut braided air ducts.

[0028] The stacking device 6 is arranged at the downstream end of the flattening device 4 and includes a pushing belt plate 7 and a stacking platform. The pushing belt plate 7 is adapted to push the stacked braided air ducts onto the stacking platform when the stacking quantity reaches the set value. Here, the pushing belt plate 7 is provided with a motion mechanism for pushing and stacking the braided air ducts to the corresponding stacking platform for storage. In a preferred embodiment, a stop induction grating and a bench scale are provided on the stacking platform, which can stop the cutting device 3 when the braided air duct blocks the stop induction grating, so as to realize the control of automatic start and stop, and prevent excessive accumulation of materials due to untimely blanking on the stacking platform.

[0029] During operation, the operator sleeves the air duct onto the front transfer device 1, starts the machine table switch to expand the front transfer device 1 outwards to stretch the woven belt, and sends the woven belt to the rear transfer device 2 through the front transfer device 1; then, the rear transfer device 2 expands after entering the braided air duct. While the rear transfer device 2 expands, the front transfer device 1 retracts to cancel the control of the braided air duct. After the rear transfer device 2 pulls the woven belt to the required cutting length, the laser and the rotating device 32 are started. The rotating device 32 drives the laser head 31 to rotate from 0° to 360.1°. During the second group of cutting, it rotates from 360.1° to 0°, and cuts back and forth; after cutting, the rear transfer device 2 sends the cut braided air duct to the flattening device 4. At the same time, the front transfer device 1 and the rear transfer device 2 repeat the previous steps to continue handling. When the rear transfer device 2 is running, the front transfer device 1 returns to the starting position at the same time; after the flattening device 4 flattens the braided air duct, it is moved in front of the flattening device 4 through the clamping device 5 to clamp one end of the flattened braided air duct and pull it to the stacking device 6, while counting; when stacked to a certain quantity, the pushing belt plate 7 pushes the stacked braided air ducts onto the stacking platform for temporary storage, and the operator packs the stacked braided air ducts.

[0030] Through the solution of this embodiment, the problem of incision adhesion affecting assembly is eliminated, the cutting efficiency is greatly improved, the hazards of high temperature and laser leakage to people are avoided. At the same time, through the flattening device 4 and the stacking device 6, it is convenient for subsequent packing and storage, and the packing efficiency is also improved; by setting the stacking stop grating, it is convenient for the operator to operate and manage multiple machine tables at the same time.
