[0029] (Embodiment 1)

[0030] See Figure 1-2 , the cloth cutting device of the present invention includes a high-speed cloth cutting mechanism, and the high-speed cloth cutting mechanism includes: a band knife 1 perpendicular to the cross-section of the to-be-processed blank cloth, and a first mold 6, a second mold 7, and a third mold 8 for shaping the to-be-processed blank cloth; parallel to the band knife 1 on both sides of the band knife 1, a secondary cross beam 2 is provided, and a first driving device 3, a second driving device 4, and a third driving device 5 are provided on the secondary cross beam 2. The first driving device 3 and the second driving device 4 respectively drive the first mold 6 and the second mold 7 to move in a direction perpendicular to the setting direction of the band knife 1, and the third driving device 5 drives the third mold 8 to move in a direction parallel to the setting direction of the band knife 1.

[0031] Specifically, the band knife is an annular knife belt 1, the annular knife belt is sleeved on the main pulley and the slave pulley, and a driving motor is installed on the main pulley. The driving motor drives the band knife to rotate at high speed along the main pulley and the slave pulley.

[0032] Parallel to the band knife 1 on both sides of the band knife 1, a secondary cross beam 2 is provided. A first driving device 3 and a second driving device 4 are provided on each secondary cross beam 2. In this embodiment, both the first driving device 3 and the second driving device 4 adopt a lead screw linear module. The first driving device 3 and the second driving device 4 are both fixed on the secondary cross beam 2 through a fixed bottom plate. The first driving device 3 includes a first lead screw 3-1, a first fixing block is provided at the output end of the first lead screw 3-1, a first slide rail is arranged in parallel on one side of the first lead screw 3-1, a first slider is fixed on the first fixing block. When the first lead screw 3-1 rotates, the first slider moves along the length direction of the first slide rail, and the first mold 6 is fixed on the first fixing block. Similarly, the second driving device 4 includes a second lead screw 4-1, a second fixing block is provided at the output end of the second lead screw 4-1, a second slide rail is arranged in parallel on one side of the second lead screw 4-1, a second slider is fixed on the second fixing block. When the second lead screw 4-1 rotates, the second slider moves along the length direction of the second slide rail, and the second mold 7 is fixed on the second fixing block. The first lead screw 3-1 and the second lead screw 4-1 are both arranged perpendicular to the setting direction of the band knife 1.

[0033] A driving mechanism 9 is fixed on the secondary crossbeam 2. In this embodiment, the driving mechanism 9 adopts a servo motor. The output shaft of the servo motor is connected to the first screw rod 3-1 through a synchronous belt. The first gear 3-2 is fixed on the first screw rod 3-1, and the second gear 4-2 is fixed on the second screw rod 4-1. The first gear 3-2 is meshed with the second gear 4-2. When the servo motor is running, the first screw rod 3-1 and the second screw rod 4-1 rotate in opposite directions, thereby driving the first mold 6 and the second mold 7 to move forward and backward relative to each other.

[0034] The first screw rod 3-1 and the second screw rod 4-1 are provided with a gear stopper 10 at the end near the gear, and the gear stopper 10 is removable. The gears on the screw rods can be replaced by removing the gear stopper 10 to replace mold plates of different models, or the gears can be directly removed so that the driving mechanism 9 only drives the first mold 6 to move.

[0035] A third driving device 5 is provided on the side wall of the secondary crossbeam, and the third driving device 5 drives the third mold 8 to move in a direction parallel to the setting direction of the band knife 1. Specifically, the third driving device 5 also adopts a screw linear module, and the third driving device 5 includes a third screw, and the third screw is arranged parallel to the setting direction of the band knife. A third fixed block is arranged on the output end of the third screw, and a third slider is fixed on the third fixed block. A third slide rail parallel to the third screw is arranged on the upper surface of the secondary crossbeam. When the third screw rotates, the third slider is driven to move along the length direction of the third slide rail, and the third mold 8 is fixed on the third fixed block. The third driving device 5 is driven by a servo motor. The third mold 8 can be linear, grid-shaped, or wavy. After installation, the first mold 6, the second mold 7, and the third mold 8 are arranged up and down.

[0036] The first mold 6 and the second mold 7 have a plurality of notches and protrusions on the side close to the band knife 1. The notches and protrusions of the first mold 6 and the second mold 7 have different shapes and / or sizes. The user can select a cloth-cutting mold of a suitable shape according to the pattern requirements. For plush cloth with a square pattern, rectangular grooves and rectangular protrusions can be selected. For wavy pattern notches, arc-shaped protrusions and arc-shaped grooves can be selected to achieve textiles with various types of patterns such as bubbles, squares, stripes, etc., which improve the fabric quality and three-dimensional sense of the textiles and can further increase the added value of the textiles.

[0037] Working mode 1: Install the first mold 6 and the third mold 8. Driven by the servo motor, the first mold 6 reciprocates and intermittently moves back and forth to produce bubble cloth and bamboo cloth. Since the total mass of a single mold plate is small, the servo drives a single mold plate to achieve a high speed and run smoothly. Practice has proved that the production speed of bubble patterns can reach 25 meters / minute.

[0038] Working mode 2: Install the first mold 6, the second mold 7 and the third mold 8. Driven by the servo motor, the first mold and the second mold move back and forth and intermittently. At the same time, the first mold 6 and the second mold 7 move relative to each other. Staggered bubble cloth surface, staggered bamboo cloth surface, and staggered checkered cloth surface can be produced. Since the total mass of a single mold plate is small and the servo-driven mold plate can reach a high speed and run smoothly, practice has verified that the production speed of bubble patterns can reach 15 meters per minute.

[0039] When the utility model is working, the auxiliary crossbeam does not move, and the driving device drives the first driving device 3 and the second driving device 4 to work, thereby driving the first mold 6 and the second mold 7 to move in a direction perpendicular to the setting direction of the band knife 1. Since the mold plate is light in weight, a high speed can be achieved and the operation is stable, which greatly accelerates the cutting speed.

[0040] (Example 2)

[0041] The difference between this embodiment and embodiment 1 is that two driving mechanisms 9 are provided, the first driving device 3 and the second driving device 4 are driven by two different driving mechanisms 9 respectively, and the first gear 3-2 and the second gear 4-2 are not provided on the first screw rod 3-1 and the second screw rod 4-1, which can speed up the production speed of complex patterned fabrics, make the logic programming more diversified, and increase the types of fabric patterns.

[0042] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
