Description

Technical Field

[0001] The utility model relates to the technical field of fabric production, in particular to a trimming mechanism of a fake leather fabric trimming machine. Background Art

[0002] Rotary cutting machines are widely used in the processing of textiles, leather, and synthetic materials. They use high-speed rotating blades to precisely cut materials. These machines are typically equipped with sophisticated control and positioning systems, enabling efficient and accurate cutting according to pre-set patterns or contours. Compared to traditional linear blade cutting, rotary cutting can handle more complex designs and reduce material waste.

[0003] Existing rotary trimming machine technology mostly uses pneumatic or electric drive, combined with advanced computer-aided design (CAD) and computer-aided manufacturing (CAM) systems, making operation more convenient and production efficiency higher. However, this technology is not perfect, especially when processing certain special materials, it encounters challenges.

[0004] While the high-speed rotating blades of a rotary trimmer provide rapid cutting speeds when cutting faux leather, they can also generate significant lateral pulling forces. Because the faux leather is coated with a plastic layer, which lacks the toughness of natural leather, it easily deforms when subjected to the pull of the rotating blades. This material deformation during the cutting process is uncontrollable. Once the cut is complete, the plastic layer's resilience as the material returns to its natural state can result in irregular, burred edges. This problem not only affects the product's appearance but can also reduce its durability. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a trimming mechanism for a faux leather fabric trimming machine, which solves the technical problem that burrs are easily generated when the prior art trimming machine is used to cut faux leather fabric.

[0006] According to an embodiment of the present invention, a trimming mechanism of a trimming machine for trimming artificial leather fabrics is provided. The trimming machine includes a conveying platform, and a trimming mechanism is provided on the conveying platform. The trimming mechanism includes:

[0007] Blade cutting mechanism: The blade cutting mechanism is arranged on the upper side of the conveying platform;

[0008] Peeling device: The peeling device is arranged on the upper side of the conveying platform and is aligned with the blade cutting mechanism;

[0009] Translation guide rail: The translation guide rail is suspended above the conveying platform, the moving direction of the translation guide rail is perpendicular to the conveying direction of the conveying platform, and the blade cutting mechanism and the rotary cutting device are both arranged on the slider of the translation guide rail.

[0010] The technical principle of the present invention is as follows: the fake leather fabric is transported through a conveying platform and first passes through a blade cutting mechanism, which first cuts the plastic material on the fake leather fabric, and then reaches a rotary cutting device aligned with the blade cutting mechanism. The rotary cutting device trims the cut position. At this time, because the plastic material has been cut, it will not be pulled during the cutting process, thereby avoiding the problem of burrs.

[0011] The translation guide rail is used to adjust the position of the blade cutting mechanism and the rotary cutting device to perform edge cutting.

[0012] Compared with the existing technology, the utility model has the following beneficial effects: through the cooperation of the blade cutting mechanism and the rotary cutting device, it solves the technical problem that burrs are easily generated when the existing trimming machine is used for cutting artificial leather fabrics, thereby ensuring the quality of the trimming of the artificial leather fabrics.

[0013] Furthermore, the blade cutting mechanism includes a cutting knife and a torsion spring. The cutting knife is hingedly connected to the slider. The torsion spring is arranged at the hinge between the cutting knife and the slider. The torsion spring applies a pressing force to the cutting knife toward the conveying platform.

[0014] Furthermore, the cutting knife is provided with a cutting edge on one side close to the conveying platform, and the conveying platform is provided with a tightening plate at a position corresponding to the cutting edge.

[0015] Furthermore, the conveying platform includes an active roller, a passive roller, and a mounting frame for mounting the active roller and the passive roller. A plurality of conveying strips are evenly distributed between the active roller and the passive roller along the length direction.

[0016] Furthermore, the peeling device includes a driving motor and a cutting wheel connected to the driving motor. The driving motor and the cutting wheel are provided with a common support frame, and the support frame is mounted on the slider.

[0017] Furthermore, a connecting bar is provided on the lower side of the support frame, the connecting bar passes through the conveying bar and is provided with a support plate, the support plate is provided with a cutting groove, and the cutting wheel is arranged in the cutting groove.

DETAILED DESCRIPTION

[0024] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-2 The trimming mechanism of the artificial leather fabric trimming machine shown in the figure comprises a conveying platform 100, on which a trimming mechanism is provided. Specifically, the conveying platform 100 comprises an active roller 110 and a passive roller 120, and a mounting frame 130 for mounting the active roller 110 and the passive roller 120. The active roller 110 is connected to a motor for providing driving force, and a number of conveying strips 140 are evenly distributed along the length direction between the active roller 110 and the passive roller 120. As for the conveying clamping mechanism 150 corresponding to the conveying strip 140 on the upper side of the conveying platform 100, it will not be described in this application.

[0026] like Figure 1-2 As shown, the trimming mechanism includes a blade cutting mechanism 200, a rotary cutting device 300 and a translation guide rail 400, wherein the blade cutting mechanism 200 and the rotary cutting device 300 are both arranged on the upper side of the conveying platform 100; and the rotary cutting device 300 is aligned with the blade cutting mechanism 200, and the artificial leather fabric passes through the blade cutting mechanism 200 first during operation.

[0027] Electric push rods 410 are provided on both sides of the translation guide rail 400, and the bottom of the electric push rods 410 are installed on both sides of the mounting frame 130, so that the translation guide rail 400 is suspended on the upper side of the conveying platform 100. The moving direction of the translation guide rail 400 is perpendicular to the conveying direction of the conveying platform 100. The blade cutting mechanism 200 and the rotary cutting device 300 are both arranged on the slider 420 of the translation guide rail 400.

[0028] like Figure 2-3As shown, the blade cutting mechanism 200 includes a cutting knife 210 and a torsion spring 220, wherein the cutting knife 210 and the slider 420 are hinged by a pin, and the torsion spring 220 is arranged at the hinged pin of the cutting knife 210 and the slider 420. The torsion spring 220 gives the cutting knife 210 a pressing force toward the conveying platform 100. The cutting knife 210 is integrally formed with a cutting blade 211 on the side close to the conveying platform 100, and the conveying platform 100 is provided with a tightening plate 131 at the position corresponding to the cutting blade 211. The tightening plate 131 is arranged on the inner side of the conveying bar 140 and is close to the upper conveying bar 140. The two ends of the tightening plate 131 are fixed on the mounting frame 130.

[0029] like Figure 3-4 As shown, the peeling device 300 includes a drive motor 310 and a cutting wheel 320 connected to the drive motor 310. The drive motor 310 and the cutting wheel 320 are provided with a common support frame 330. The support frame 330 is installed on the slider 420 so that the slider 420 can drive the drive motor 310 and the cutting wheel 320 to move, and the cutting wheel 320 is aligned with the cutting blade 211.

[0030] A connecting bar 331 is provided on the lower side of the specific support frame 330. The connecting bar 331 passes through the transmission bar 140 and is integrally formed with a support plate 332. A cutting groove 321 is provided on the support plate 332. The cutting wheel 320 is arranged in the cutting groove 321, and the connecting bar 331 is located on the side away from the cutting knife 210 to provide support force for the cutting of the cutting wheel 320.

[0031] The significance of the existence of the conveying bar 140 is that, because the artificial leather material is heavy, the friction between it and the conveying bar 140 is also large, so even without the conveying and pressing mechanism 150 , the artificial leather material can be driven to move.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
