[0017] Beneficial effects of the present invention:

[0018] (1) When the unwinding motor is started, the sound-absorbing cotton tape begins to unwind from the material tray, and passes through the guide roller, tension roller and feed roller in turn before entering the traction mechanism. The traction mechanism is used to pull the tape forward, and the roller mechanism is used to roll and flatten the tape, so that the tape enters the cutting mechanism smoothly. The cutting mechanism is used to cut the tape to a fixed length, and finally the unloading mechanism is used to transfer the cut sound-absorbing cotton tape to the unloading conveyor table, thereby realizing the integrated processing process of loading, pulling, rolling, cutting and unloading the sound-absorbing cotton tape. The whole process is automatic loading and unloading, with a high degree of automation, which can effectively improve the processing efficiency.

[0019] (2) By setting up a traction mechanism, when the sound-absorbing cotton material strip is squeezed into between the upper and lower groups of traction and extrusion rollers, the traction motor is started, and the driving shaft drives the driving wheel to rotate. The driving wheel drives the transmission wheel to rotate through the circular transmission belt, so that the traction and extrusion rollers can rotate along the circular transmission belt, so that the upper and lower groups of traction and extrusion rollers can clamp the material strip and pull it forward for transportation. At the same time, the power motor drives the traction and extrusion rollers to rotate, and the upper and lower groups of traction and extrusion rollers rotate in opposite directions, so that the traction and extrusion rollers can roll and squeeze the material strip during the transportation process, thereby realizing the process of traction and flattening the material strip, which can effectively eliminate the wrinkles on the surface of the sound-absorbing cotton material strip, making its surface smooth, which is conducive to the cutting process.

[0020] (3) By setting up a cutting mechanism, the distance between the limit bracket and the cutting blade is adjusted by using the distance-adjusting electric rail. At the same time, the distance between the limit bracket and the cutting blade is changed in real time by using the displacement sensor to accurately adjust the displacement distance. When the material strip is pulled and transported to the carrier, the end of the material strip will be blocked and limited by the baffle. At this time, the conveying is stopped, so that the material strip can be cut to a fixed length. At the same time, the extrusion cylinder pushes the pressure plate downward so that the pressure plate tightly presses one end of the material strip to prevent the material strip from curling during the cutting process. When the material strip is limited and pressed, the cutting cylinder pushes the shell downward until the positioning pressure strip presses the material strip against the two ends of the cutting groove, so that the material strip remains flat and tensioned at both ends of the cutting groove. At this time, the electric telescopic rod is used to push the connecting plate downward, and the tensioned material strip is cut by the cutting blade. The incision is flat and not prone to curling, which is conducive to improving the cutting effect. BRIEF DESCRIPTION OF THE DRAWINGS

After the sound-absorbing cotton material belt is unwound from the material tray 21, it passes through the guide roller 24, the tensioning roller 25 and the feed roller 26 in sequence.

[0034] Specifically, when the unwinding motor 23 is started, the sound-absorbing cotton material strip begins to unwind from the material tray 21, and passes through the guide roller 24, the tensioning roller 25 and the feed roller 26 in sequence before entering the traction mechanism 4, the traction mechanism 4 is used to pull and convey the material strip forward, and the rolling mechanism 5 is used to roll and flatten the material strip, so that the material strip enters the cutting mechanism 7 smoothly, and the cutting mechanism 7 is used to cut the material strip to a fixed length, and finally the unloading mechanism 8 is used to transfer and convey the cut sound-absorbing cotton material strip to the discharge conveyor table 9, thereby realizing the integrated processing process of loading, traction, rolling, cutting and unloading of the sound-absorbing cotton material strip, and the whole process is automatically loaded and unloaded, with a high degree of automation, which can effectively improve the processing efficiency.

[0035] like Figure 2 and Figure 3 As shown, two groups of traction mechanisms 4 are provided, and the two groups are symmetrically arranged in the upper and lower parts. Each group of traction mechanisms 4 includes a pair of side plates 41, the side plates 41 are fixedly connected to the first bracket 3, and a driving shaft 43 and a transmission shaft 45 are rotatably installed between the side plates 41. A traction motor 42 is fixedly provided on one side of the side plate 41, and the output end of the traction motor 42 is connected to the driving shaft 43. Driving wheels 44 are provided at both ends of the driving shaft 43, and transmission wheels 46 are provided at both ends of the transmission shaft 45. A circulating transmission belt 47 is provided between the driving wheel 44 and the corresponding transmission wheel 46, and fixed seats 471 are fixedly provided at equal intervals on the circulating transmission belt 47. Traction and extrusion rollers 49 are rotatably installed between the opposite fixed seats 471, and a power motor 472 is fixedly provided on the side wall of the fixed seat 471. The output end of the power motor 472 is connected to the traction and extrusion roller 49. The upper and lower opposite traction and extrusion rollers 49 have the same transmission direction and opposite rotation directions. The sound-absorbing cotton material belt is squeezed through the gap between the upper and lower groups of traction and extrusion rollers 49.

[0036] Specifically, by setting up the traction mechanism 4, when the sound-absorbing cotton material strip is squeezed into between the upper and lower groups of traction and extrusion rollers 49, the traction motor 42 is started, and the driving shaft 43 drives the driving wheel 44 to rotate, and the driving wheel 44 drives the driving wheel 46 to rotate through the circulating transmission belt 47, so that the traction and extrusion rollers 49 can rotate along the circulating transmission belt 47, so that the upper and lower groups of traction and extrusion rollers 49 can clamp the material strip and pull it forward for transportation. At the same time, the power motor 472 drives the traction and extrusion rollers 49 to rotate, and the upper and lower groups of traction and extrusion rollers 49 rotate in opposite directions, so that the traction and extrusion rollers 49 can roll and squeeze the material strip during the transportation process, thereby realizing the process of traction and flattening the material strip, which can effectively eliminate the wrinkles on the surface of the sound-absorbing cotton material strip, make its surface smooth, and facilitate the cutting process.

[0037] It should be noted that in the present embodiment, at least two groups of traction and squeezing rollers 49 are arranged in each group of traction mechanisms 4. When one group of traction and squeezing rollers 49 releases the squeezing effect on the material belt from one end, the other group of traction and squeezing rollers 49 will rotate to the other end and begin to contact the material belt for alignment and clamping and traction, thereby realizing the continuous traction and conveying process of the material belt by guiding the circumferential rotation of the traction and squeezing rollers 49 through the circulating transmission belt 47.

[0038] like Figure 3 As shown, an abutment plate 48 is arranged inside the circulating transmission belt 47 , and the abutment plate 48 is fixedly connected to the side plate 41 , and the inner surface of the circulating transmission belt 47 is arranged against the abutment plate 48 .

[0039] Specifically, by providing the abutment plate 48, the abutment plate 48 will support and limit the circulating driving belt, so that the circulating driving belt 47 can always be transported in the correct direction during the circulating rotation process, avoiding its bending and deformation.

[0040] like Figure 4 As shown, the rolling mechanism 5 includes a pair of rolling brackets 51, and the rolling brackets 51 are fixedly connected to the side plate 41. Floating slide grooves 511 are provided at the upper and lower ends of the rolling brackets 51. Floating sliders 52 are slidably installed in the floating slide grooves 511. Floating pressure rollers 53 are rotatably installed between the relative floating sliders 52, and the sound-absorbing cotton material belt is squeezed through the gap between the upper and lower groups of floating pressure rollers 53.

[0041] Furthermore, a floating spring 54 is provided between the floating slider 52 and the floating slide groove 511 , and a limiting slide rod 55 is provided at each end of the floating slider 52 , and the limiting slide rod 55 slides through the rolling bracket 51 .

[0042] Specifically, by setting up the rolling mechanism 5, when the material strip is pulled and transported between the upper and lower groups of floating pressure rollers 53, the floating pressure roller 53 will rotate between the floating sliders 52, so as to flatten the material strip. At the same time, the floating pressure roller 53 can slide up and down in the floating slide groove 511 through the floating slider 52, so as to maintain a certain floating space, and under the elastic force of the floating spring 54, the floating pressure roller 53 can always be against the upper and lower surfaces of the material strip, so as to realize the rolling and flattening process of sound-absorbing cotton material strips of different thicknesses.

[0043] like Figure 5 , Figure 6 and Figure 7 As shown, the cutting mechanism 7 includes a cutting seat 71, a cutting bracket 72 is fixedly provided on the upper end of the cutting seat 71, a cutting cylinder 73 is fixedly provided on the upper end of the cutting bracket 72, the output end of the cutting cylinder 73 is connected to a shell 74, an electric telescopic rod 741 is fixedly provided on the top of the shell 74, a connecting plate 742 is connected to the output end of the electric telescopic rod 741, a cutting blade 743 is fixedly installed on the bottom of the connecting plate 742, a through opening for the cutting blade 743 to pass through is penetrated at the bottom of the shell 74, positioning strips 746 are extended downwardly on both sides of the bottom of the shell 74, and a cutting groove 711 opposite to the cutting blade 743 is fixedly provided on the upper end of the cutting seat 71.

[0044] Furthermore, a pressure sensor 744 is fixedly provided on the top of the connecting plate 742 , and a return spring 745 is provided between the bottom of both ends of the connecting plate 742 and the housing 74 .

[0045] like Figure 5 , Figure 6 and Figure 8 As shown, a supporting platform 75 is fixedly provided on one side of the cutting seat 71, and distance-adjusting electric rails 751 are provided on both sides of the supporting platform 75. A limiting bracket 76 is slidably installed on the distance-adjusting electric rail 751 through a slide 761. A baffle 762 is fixedly provided in the limiting bracket 76, and the bottom of the baffle 762 is abutted against the upper surface of the supporting platform 75. A pressing plate 763 is provided on one side of the baffle 762. An extrusion cylinder 764 is fixedly provided on the top of the limiting bracket 76, and the output end of the extrusion cylinder 764 is connected to the pressing plate 763. Guide rods 765 are fixedly provided on both sides of the upper end of the pressing plate 763, and the guide rods 765 slide through the limiting bracket 76.

[0046] Furthermore, a buffer spring 766 is provided between the upper end of the pressure plate 763 and the baffle 762 , and a displacement sensor 767 is fixedly provided at one end of the limiting bracket 76 close to the shell 74 .

[0047] Specifically, by setting the cutting mechanism 7, the distance between the limit bracket 76 and the cutting blade 743 is adjusted by the distance adjustment electric rail 751, and the distance between the limit bracket 76 and the cutting blade 743 is changed in real time by the displacement sensor 767 to accurately adjust the displacement distance. When the material strip is pulled and transported to the carrier 75, the end of the material strip will be blocked and limited by the baffle 762, and the conveying is stopped at this time, so that the fixed length cutting of the material strip can be achieved. At the same time, the extrusion cylinder 764 pushes the pressing plate 763 downward, so that the pressing plate 763 is tightly pressed. The cutting blade 743 is used to cut the tensioned strip, and the cut is smooth and not prone to curling, which is beneficial to improving the cutting effect.

[0048] like Figure 5 As shown, the unloading mechanism 8 includes a transverse driving pair 81, a mounting plate 82, a longitudinal driving pair 83 and a mounting platform 84. The mounting plate 82 is horizontally slidably mounted on the transverse driving pair 81, the longitudinal driving pair 83 is fixedly arranged at the front end of the mounting plate 82, and the mounting platform 84 is slidably mounted on the longitudinal driving pair 83 up and down. A suction cup fixture 85 for grabbing the cut sound-absorbing cotton is fixedly arranged on one side of the mounting platform 84.

[0049] Specifically, by setting up a unloading mechanism 8, a suction cup fixture 85 is used to grab the cut sound-absorbing cotton material strip on the supporting platform 75, and then the sound-absorbing cotton material strip is transferred and transported to the unloading conveying platform 9 through the transverse drive pair 81 and the longitudinal drive pair 83 to realize the unloading process.

[0050] The working principle of the present invention is as follows: Figure 1-Figure 8As shown, when in use, the unwinding motor 23 is started, the sound-absorbing cotton material belt begins to unwind from the material tray 21, and passes through the guide roller 24, the tensioning roller 25 and the feed roller 26 in sequence before entering the traction mechanism 4. When the sound-absorbing cotton material belt is squeezed into between the upper and lower groups of traction and extrusion rollers 49, the traction motor 42 is started, and the driving shaft 43 drives the driving wheel 44 to rotate. The driving wheel 44 drives the driving wheel 46 to rotate through the circulating transmission belt 47, so that the traction and extrusion rollers 49 can rotate along the circulating transmission belt 47, so that the upper and lower groups of traction and extrusion rollers 49 can clamp the material belt and traction and convey it forward. At the same time, the power motor 472 drives the traction and extrusion rollers 49 to rotate, and the upper and lower groups of traction and extrusion rollers 49 rotate in opposite directions, so that the traction and extrusion rollers 49 can roll and squeeze the material belt during the conveying process, thereby realizing the process of traction and flattening the material belt, which can effectively eliminate the wrinkles on the surface of the sound-absorbing cotton material belt, making its surface smooth, which is beneficial to the cutting process. When the material strip is pulled and transported between the upper and lower sets of floating pressure rollers 53, the floating pressure rollers 53 will rotate between the floating sliders 52, so as to flatten the material strip. At the same time, the floating pressure rollers 53 can slide up and down in the floating slide groove 511 through the floating slider 52, so as to maintain a certain floating space, and under the elastic force of the floating spring 54, the floating pressure rollers 53 can always rest against the upper and lower surfaces of the material strip, so as to realize the rolling and flattening process of sound-absorbing cotton material strips of different thicknesses. When the material strip is pulled and conveyed to the carrier 75, the end of the material strip will be blocked and limited by the baffle 762, and the conveying will be stopped at this time, so that the fixed length cutting of the material strip can be realized. At the same time, the extrusion cylinder 764 pushes the pressing plate 763 downward, so that the pressing plate 763 presses one end of the material strip tightly to prevent the material strip from warping during the cutting process. When the material strip is limited and pressed, the cutting cylinder 73 will push the shell 74 downward until the positioning pressure strip 746 presses the material strip against the two ends of the cutting groove 711, so that the material strip remains flat and tensioned at both ends of the cutting groove 711. At this time, the electric telescopic rod 741 is used to push the connecting plate 742 downward, and the cutting blade 743 is used to cut the tensioned material strip. The sound-absorbing cotton material strip cut on the carrier 75 is grabbed by the suction cup fixture 85, and then the sound-absorbing cotton material strip is transferred and conveyed to the unloading conveying platform 9 through the transverse drive pair 81 and the longitudinal drive pair 83 to realize the unloading process.

[0051] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
