Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, specifically to a cutting device for automotive nonwoven fabric. Background Technology

[0002] Non-woven fabric is a new generation of environmentally friendly material. It has the characteristics of being moisture-proof, breathable, flexible, lightweight, non-flammable, easy to decompose, non-toxic and non-irritating, rich in color, inexpensive, and recyclable. Non-woven fabric has a wide range of uses in automobiles and has gradually replaced many materials such as automotive interior trim and sound insulation cotton. Non-woven fabric can be cut by cutting equipment to be processed into automotive interior trim.

[0003] For example, CN222923505U discloses a fixed-length cutting device for the production of nonwoven fabric for automotive headliners, including a worktable and support columns. The support columns are fixedly connected to the four lower corners of the worktable, and a cutting mechanism is connected to the upper end of the worktable. When cutting the nonwoven fabric for automotive headliners, the fixed-length cutting device first places the nonwoven fabric to be cut on the worktable, then slides the slider along the inner side of the slide groove to move the cutting blade to the nonwoven fabric cutting position, then holds the pull rod and presses down to move the lower cutting blade down until the cutting blade moves onto the nonwoven fabric. At the same time, the pressure plate moves to the upper end of the nonwoven fabric to press the nonwoven fabric at both ends of the cutting blade. Then, the moving block slides back and forth along the outer side of the limiting rod to move the lower cutting blade onto the nonwoven fabric to cut the nonwoven fabric.

[0004] While the aforementioned patent has many advantages, the existing technology uses a manually driven cutting blade for cutting, which is labor-intensive when cutting large quantities of non-woven fabric. Furthermore, the processing efficiency is generally low, reducing its practicality. Utility Model Content

[0025] Please see Figure 1 The non-woven fabric cutting device for automobiles in this embodiment includes a support platform 1, a support frame 2 fixed on the back of the support platform 1, a cutting component on the support frame 2, and a clamping assembly 3 on the support platform 1.

[0026] In this embodiment, the cutting component includes a first electric push rod 4 fixed to the upper surface of the support frame 2 by a mounting bracket. The outer side of the output shaft of the first electric push rod 4 slides through the support frame 2 and extends into the interior. A mounting plate 5 is fixed to the outer side of the output shaft of the first electric push rod 4, and a cutting tool 6 is fixed to the lower surface of the mounting plate 5.

[0027] Specifically, a protective frame is fixed to the back wall of the inner cavity of the support platform 1, and the cutting tool 6 is located inside the protective frame. The support platform 1 includes a table plate, and support plates are fixed to the left and right sides of the lower surface of the table plate.

[0028] It should be noted that when the non-woven fabric is fixed and then cut, the first electric push rod 4 is activated, which drives the mounting plate 5 and the cutting blade 6 to move downward. Under the drive of the mounting plate 5, the cutting blade 6 cuts the non-woven fabric located on the cutting table. After the cutting is completed, the output axis of the first electric push rod 4 retracts upward, and the cutting blade 6 returns to its initial position.

[0029] Please see Figures 2 to 4 In this embodiment, the clamping assembly 3 includes a rectangular sliding rod 301 fixed inside the support platform 1. Two connecting rods 302 are slidably connected to the outer side of the rectangular sliding rod 301. U-shaped frames 303 are fixed to the outer side of the connecting rods 302 on both the left and right sides. Sliding openings 304 are provided through the front and rear sides of the upper surface of the support platform 1. The U-shaped frames 303 on both the left and right sides are slidably connected inside the sliding openings 304 on both the front and rear sides. A driving component is provided on the support platform 1, and a pressing component is provided on the U-shaped frames 303 on both the left and right sides.

[0030] Specifically, the driving component includes a connecting plate 305 fixed inside the support platform 1. A second electric push rod 306 is fixed to the lower surface of the connecting plate 305 by a mounting bracket. The outer side of the output of the second electric push rod 306 slides through the connecting plate 305 and extends to the upper side. A moving block 307 is fixed to the outer side of the output shaft of the second electric push rod 306. The lower surfaces of the left and right U-shaped frames 303 are both hinged with fixed rods 308 by hinge seats. The opposite sides of the left and right fixed rods 308 are hinged to the left and right sides of the moving block 307 by hinge seats, which ensures cutting quality, improves processing efficiency, and reduces cutting labor.

[0031] Specifically, the pressing component includes a third electric push rod 309 fixed to the upper surface of the left and right U-shaped frames 303 by a mounting bracket. The outer sides of the output shafts of the left and right third electric push rods 309 slide through the left and right U-shaped frames 303 and extend into them. The outer sides of the output shafts of the left and right third electric push rods 309 are fixed with a pressing plate 310. The lower surface of the pressing plate 310 is fixed with a rubber layer 311. The U-shaped frame 303 moves linearly left and right inside the sliding openings 304 on the front and rear sides. A cutting table is fixed on the upper surface of the support platform 1. The cutting table is located between the opposite sides of the sliding openings 304 on the front and rear sides. Each connecting rod 302 includes a rod body. A rectangular sliding hole is opened through the left side of the rod body.

[0032] It should be noted that before cutting, the non-woven fabric needs to be fixed on the cutting table. At this time, the output shafts of the third electric push rods 309 on both sides extend downward, driving the lower pressure plates 310 on both sides to move downward, pressing the non-woven fabric tightly on the cutting table. The rubber layer 311 on the lower surface of the lower pressure plate 310 contacts the non-woven fabric, increasing friction and preventing the non-woven fabric from sliding during the cutting process. If different lengths of non-woven fabric are to be fixed, the output shaft of the second electric push rod 306 is activated to extend and retract, driving the moving block 307 to move up and down. Through the fixing rods 308 on both sides, the U-shaped frames 303 on both sides can move in opposite directions or in opposite directions, thereby changing the distance between the U-shaped frames 303 on both sides, so as to clamp and fix non-woven fabrics of different lengths.

[0033] The working principle of the above embodiments is as follows:

[0034] During use, before cutting, the non-woven fabric needs to be fixed on the cutting table. At this time, the output shafts of the third electric push rods 309 on both sides extend downward, driving the lower pressure plates 310 on both sides to move downward, pressing the non-woven fabric firmly onto the cutting table. The rubber layer 311 on the lower surface of the lower pressure plate 310 contacts the non-woven fabric, increasing friction and preventing the non-woven fabric from sliding during the cutting process. If different lengths of non-woven fabric are fixed, the output shaft of the second electric push rod 306 is activated to extend and retract, driving the moving block 307 to move up and down. The rod 308 and the U-shaped frames 303 on the left and right sides can move in opposite directions or in opposite directions to change the distance between the U-shaped frames 303 on the left and right sides, so as to clamp and fix non-woven fabrics of different lengths. When cutting after fixing the non-woven fabric, the first electric push rod 4 is activated, which drives the mounting plate 5 and the cutting tool 6 to move downward. Under the drive of the mounting plate 5, the cutting tool 6 cuts the non-woven fabric located on the cutting table. After the cutting is completed, the output axis of the first electric push rod 4 retracts upward, and the cutting tool 6 returns to the initial position.
