[0028] refer to Figures 1 to 9 :

[0029] A cutting device used in carpet manufacturing includes a frame 1, a carrying roller 2 rotatably arranged on the frame 1, a support frame 5 fixedly arranged above the carrying roller 2, a cutting wheel 6 arranged on the support frame 5, a speed-increasing mechanism 8 and an adsorption unit 16 arranged on one side of the frame 1, the carrying roller 2 is used to transport the carpet body 3, the cutting wheel 6 is used to cut off the edge strip 4 from the carpet body 3, the speed-increasing mechanism 8 includes a power input end and a speed-increasing output end, the adsorption unit 16 includes a suction machine 23 arranged beside the cutting wheel 6 and a collecting bag 25 arranged below the suction machine 23, the power input end of the speed-increasing mechanism 8 is transmission-connected to the carrying roller 2, and the power input shaft of the suction machine 23 is transmission-connected to the speed-increasing output end of the speed-increasing mechanism 8.

[0030] When the device is in operation, the carpet body 3 is transported by the carrying roller 2 on the frame 1, and the cutting wheel 6 arranged on the supporting frame 5 trims the carpet body 3 (it should be noted that there are two cutting wheels 6, which are arranged at both ends of the supporting frame 5 and are used to trim the two sides of the carpet body 3). As the device is running, the cutting wheel 6 cuts the edge strip 4 from the carpet body 3, and then the edge strip 4 is collected and processed, and the trimmed carpet body 3 is rewound. During the cutting process, the rotation of the carrying roller 2 is transmitted through the power input end of the speed-up mechanism 8, so that the speed-up output end of the speed-up mechanism 8 drives the suction machine 23 to operate. The suction machine 23 operates to absorb the fluff generated by the cutting wheel 6 cutting the side of the carpet body 3 in time, and then discharges it into the collection bag 25 for collection.

[0031] In order to show the installation structure of the cutting wheel 6, the following features are also specifically provided:

[0032] The support frame 5 is provided with a protective cover 7 , and the cutting wheel 6 is rotatably disposed in the protective cover 7 , and the protective cover 7 is fixedly connected to the support frame 5 .

[0033] It should be noted that the protective cover 7 can be adjusted in the vertical direction on the support frame 5, so that the cutting wheel 6 can adapt to cutting environments of different thicknesses. When the thickness of the carpet body 3 changes, the position of the protective cover 7 is adjusted to make the cutting wheel 6 reach a suitable cutting position, ensuring that the device can perform edge trimming on carpet bodies 3 of various sizes.

[0034] In order to show the detailed structure of the speed increasing mechanism 8, the following features are also specifically provided:

[0035] The speed-increasing mechanism 8 includes a support frame 9, a transmission ring gear 10, a connecting plate 11, a limiting bracket 14, planetary gears 15, a sun gear 12 and a connecting shaft 13. The support frame 9 is fixedly connected to the frame 1, the transmission ring gear 10 is rotatably arranged on the support frame 9, the carrying roller shaft 2 is coaxially fixedly connected to the connecting plate 11, the transmission ring gear 10 is coaxially fixedly connected to the connecting plate 11, the limiting bracket 14 is fixedly arranged on the support frame 9, there are four planetary gears 15, which are distributed in a ring along the axis of the transmission ring gear 10, each planetary gear 15 is rotatably connected to the limiting bracket 14, the connecting shaft 13 is coaxially fixedly connected to the power input shaft of the suction machine 23, the sun gear 12 is coaxially fixedly connected to the connecting shaft 13, the transmission ring gear 10 is meshed with each planetary gear 15, and each planetary gear 15 is meshed with the sun gear 12.

[0036] The connecting plate 11 is the power input end of the speed increasing mechanism 8 , and the connecting shaft 13 is the speed increasing output end of the speed increasing mechanism 8 .

[0037] When the device is running, the carrying roller 2 drives the connecting plate 11 to rotate, the connecting plate 11 drives the transmission ring gear 10 to rotate, the transmission ring gear 10 engages the planetary gear 15 to drive the sun gear 12 to rotate (the gear transmission structure here is the planetary gear principle), so that the sun gear 12 is accelerated, and then the sun gear 12 drives the connecting shaft 13 to rotate, and the rotation of the connecting shaft 13 drives the suction machine 23 to operate.

[0038] In order to show the detailed structure of the adsorption unit 16, the following features are also specifically provided:

[0039] The adsorption unit 16 also includes a limit plate 17 fixedly arranged on the frame 1 and a support plate 22 fixedly arranged on the support frame 9. The suction machine 23 is fixedly connected to the support plate 22. A suction port 19 is opened on the limit plate 17, and the suction port of the suction machine 23 is connected to the suction port 19.

[0040] (It should be noted that there are two suction machines 23 , which are arranged one by one corresponding to the cutting wheels 6 ) When the cutting wheel 6 cuts the carpet body 3 , the generated fluff is discharged through the suction port 19 , sucked by the suction machine 23 , and finally falls into the collection bag 25 .

[0041] In order to ensure that the lint generated by cutting the carpet can be better collected when the device is running, the following features are also set:

[0042] The limiting plate 17 is provided with an arc-shaped baffle 18 , and the arc-shaped baffle 18 is fixedly disposed above the adsorption port 19 .

[0043] When the device is running, the fluff generated by cutting is blocked by the arc-shaped baffle 18 to prevent the fluff from flying around. In addition, when the suction machine 23 is running, a certain adsorption force will be generated at the arc-shaped baffle 18, which further allows the fluff to stay at the arc-shaped baffle 18 for a while and then enter the interior of the suction machine 23 through the adsorption port 19.

[0044] In order to ensure that the fluff does not fly everywhere, the following features are also set:

[0045] The adsorption unit 16 also includes a flow guide hood 20, a feed box 21 and a conveying hood 24. The flow guide hood 20 is arranged on the adsorption port 19 and is fixedly connected to the limit plate 17. The feed box 21 is arranged at the suction port of the suction machine 23. One end of the feed box 21 is fixedly connected to the flow guide hood 20, and the other end is fixedly connected to the suction machine 23. The conveying hood 24 is fixedly arranged below the discharge port of the suction machine 23, and a collection bag 25 is fixedly arranged below the conveying hood 24.

[0046] When the device is running, the fluff produced by cutting is blocked by the arc-shaped baffle 18, and then enters the guide cover 20 from the suction port 19, and is gathered by the feed box 21 and enters the suction machine 23, and finally is discharged from the discharge port of the suction machine 23 into the conveying cover 24, and then enters the collection bag 25. Through the above treatment, the problem of flying fluff during the cutting process is solved.

[0047] In order to ensure that the fluff is not easy to fall off after being collected, the following features are also set:

[0048] A fastening ring 26 is provided on the conveying cover 24, and the fastening ring 26 is a buckle structure.

[0049] By providing a fastening ring 26 with a buckle structure, when the collecting bag 25 is full of fluff, the collecting bag 25 can be quickly replaced, thus saving working time.

[0050] In order to prevent the accumulation of fluff between the feed box 21 and the flow guide cover 20 when the device is running, the following features are specifically provided:

[0051] The adsorption unit 16 also includes an anti-blocking mechanism, which includes a vibration box 33 slidably arranged on the feed box 21, a support plate 34 fixedly arranged in the middle of the vibration box 33, a return spring 35 fixedly arranged on both sides of the support plate 34, a touch block 37 fixedly arranged on the side wall of the vibration box 33, a limit tube 27 fixedly arranged on the support plate 22, a connecting shaft 28 coaxially rotatably arranged in the limit tube 27, a driven wheel 29 coaxially fixedly arranged at one end of the connecting shaft 28, and a driven wheel 29 coaxially fixedly arranged at the other end of the connecting shaft 28. A toggle disc 31 at one end, a toggle block 32 fixedly arranged on the toggle disc 31, a driving wheel 36 coaxially fixedly arranged on the connecting shaft 13, and a connecting belt 30 arranged between the driving wheel 36 and the connecting shaft 13, a limit block 38 located above the supporting plate 34 is fixedly connected to the air guide cover 20, and a limit block 38 located below the supporting plate 34 is fixedly connected to the feed box 21, and return springs 35 are arranged on both sides of the supporting plate 34, one end of the return spring 35 is fixedly connected to the supporting plate 34, and the other end is fixedly connected to the limit block 38.

[0052] When the device is running, the connecting shaft 13 rotates to drive the driving wheel 36 to rotate, and the driving wheel 36 rotates to drive the driven wheel 29 to rotate through the connecting belt 30. The driven wheel 29 rotates to drive the connecting shaft 28 to rotate. The connecting shaft 28 rotates to drive the dial disk 31 to rotate. The rotation of the dial disk 31 drives the dial block 32 to make a circular motion, causing the dial block 32 to intermittently collide with the contact block 37, thereby causing the vibration box 33 to vibrate. During this process, the reset spring 35 adaptively contracts and vibrates the vibration box 33 to prevent hair from accumulating in the feed box 21.

[0053] The working principle of the device is as follows: when the cutting wheel 6 cuts the carpet body 3, the carrying roller 2 drives the connecting plate 11 to rotate, the connecting plate 11 drives the transmission gear ring 10 to rotate, the transmission gear ring 10 engages with the planetary gear 15 to drive the sun gear 12 to rotate, the sun gear 12 drives the connecting shaft 13 to rotate, the connecting shaft 13 rotates to drive the suction machine 23 to run, the fluff produced by the cutting is blocked by the arc baffle 18 to prevent the fluff from flying around, and then the fluff enters the guide cover 20 from the suction port 19, and then is gathered by the feed box 21 and enters the suction machine 23, and finally is discharged from the discharge port of the suction machine 23 into the conveying cover 24 , and then enter the collection bag 25. In the above process, the connection shaft 13 rotates to drive the driving wheel 36 to rotate, and the driving wheel 36 rotates to drive the driven wheel 29 to rotate through the connecting belt 30. The driven wheel 29 rotates to drive the connecting shaft 28 to rotate, and the connecting shaft 28 rotates to drive the dial disc 31 to rotate. The dial disc 31 rotates to drive the dial block 32 to make a circular motion, causing the dial block 32 to intermittently hit the contact block 37, so that the vibration box 33 vibrates. In this process, the reset spring 35 shrinks adaptively and vibrates the vibration box 33 to prevent the lint from accumulating in the feed box 21. At this point, the collection and processing of the lint is completed, and the cut carpet body 3 is rewound by the subsequent collection device, and the cut edge strips 4 are collected and can be recycled according to the situation to prevent waste.

[0054] The above embodiments only express one or several implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
