Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically to a feeding mechanism for a nonwoven fabric slitting machine. Background Technology

[0002] A nonwoven fabric slitting machine is a mechanical device that cuts wide-width nonwoven fabrics, paper, mica tape, or films into multiple narrow strips. It is widely used in the production of nonwoven products, the manufacturing of medical and hygiene products, and the processing of automotive interior materials. The working principle of a nonwoven fabric slitting machine is mainly based on mechanical transmission and cutting technology. During operation, the nonwoven fabric material is fed into the machine, and after positioning and pressing, it is cut by high-speed rotating blades. During the cutting process, the machine automatically adjusts according to preset parameters (such as cutting width and speed) to ensure cutting accuracy and efficiency.

[0003] In actual use, the large width of the uncut nonwoven fabric results in a large size and weight of the nonwoven fabric roll, which is very inconvenient to feed, leading to low feeding efficiency and affecting the nonwoven fabric cutting efficiency.

[0004] Therefore, it is necessary to invent a feeding mechanism for nonwoven fabric slitting machines to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding mechanism for a nonwoven fabric slitting machine, so as to solve the problem that the unslit nonwoven fabric is too wide, resulting in a large size and weight of the nonwoven fabric roll, which makes feeding very inconvenient, and thus leads to low feeding efficiency and affects the nonwoven fabric slitting efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism for a nonwoven fabric slitting machine, comprising a device support, a feeding roller on the right side of the device support, a pressure roller on the upper side of the feeding roller, a roll of nonwoven fabric on the surface of the feeding roller, a fixing frame fixedly connected to both the front and rear sides of the right end of the device support, a limit screw threadedly connected to the upper end of the fixing frame, and feeding components on both the front and rear sides of the right end of the device support, the feeding components comprising a first connecting block, a first feeding rod, a second feeding rod, a limit rod, a support shaft, a connecting sleeve, a second connecting block, and a hydraulic cylinder.

[0007] By adopting the above technical solution, the feeding roller and the pressure roller work together to unwind the nonwoven fabric roll. During the feeding process, the nonwoven fabric roll is first fixed on the surface of the feeding roller. Then, the first feeding rod and the second feeding rod are rotated to an inclined position by the hydraulic cylinder. Next, the two ends of the feeding roller are rolled to the upper side of the second feeding rod on both sides. At this time, the hydraulic cylinder rotates the first feeding rod and the second feeding rod to a horizontal position and lifts the nonwoven fabric roll upward. Then, the two ends of the feeding roller are rolled to the inner side of the fixing frame for fixing. This completes the feeding of the nonwoven fabric roll, improving the convenience and efficiency of feeding.

[0008] Optionally, a connecting shaft is fixedly connected inside the feeding roller, and fixed bearings are rotatably connected to both ends of the connecting shaft. The fixed bearings are locked inside the fixed frame, and the limiting screw is locked on the right side of the fixed bearing.

[0009] By adopting the above technical solution, the fixed bearing is fixed inside the fixed frame, and the connecting shaft rotates inside the fixed bearing.

[0010] Optionally, a servo motor is fixedly installed on the front side of the right end of the equipment bracket, a first gear is fixedly connected to the output end of the servo motor, and a second gear is fixedly connected to the front end of the connecting shaft, with the first gear and the second gear meshing together.

[0011] By adopting the above technical solution, the servo motor, the first gear and the second gear work together to drive the feeding roller to rotate and feed the nonwoven fabric roll.

[0012] Optionally, the two sets of first connecting blocks are fixedly connected to the front and rear sides of the right end of the equipment bracket, the left end of the first feeding rod is rotatably connected to the first connecting block, the left end of the second feeding rod is rotatably connected to the right end of the first feeding rod, the limiting rod is fixedly connected to the right end of the second feeding rod, and positioning rods are fixedly connected to the upper surfaces of the first connecting block, the first feeding rod, and the second feeding rod.

[0013] By adopting the above technical solution, the second feeding rod is unfolded during the feeding process and folded to the side of the first feeding rod during the unwinding process, reducing the space occupied. At the same time, the positioning rod is used to position the two sets of fixed bearings so that they can be accurately locked inside the fixed frame.

[0014] Optionally, the second connecting block is rotatably connected to the lower end of the hydraulic cylinder, the second connecting block is fixedly connected to the lower right end of the equipment support, the connecting sleeve is fixedly connected to the upper end of the piston rod in the hydraulic cylinder, the support shaft is fixedly connected to the lower right side of the first feeding rod, and the connecting sleeve is rotatably connected to the support shaft.

[0015] By adopting the above technical solution, during the extension and retraction of the telescopic rod in the hydraulic cylinder, the support shaft is pushed up and down, thereby pushing the first feeding rod to rotate around the first connecting block.

[0016] Optionally, a first fixing block is fixedly connected to the right end of the surface of the two sets of first feeding rods that are close to each other, and a second fixing block is fixedly connected to the left end of the surface of the two sets of second feeding rods that are close to each other, and the second fixing block is rotatably connected to the first fixing block.

[0017] By adopting the above technical solution, the first fixing block rotates around the second fixing block, thereby causing the second feeding rod to rotate around the first feeding rod, which facilitates folding the second feeding rod to the side of the first feeding rod.

[0018] Optionally, a first locking block is fixedly connected to the right end of the opposite side surface of the two sets of first feeding rods, and a second locking block is fixedly connected to the left end of the opposite side surface of the two sets of second feeding rods. Both the second locking block and the first locking block have through holes on their surfaces, and a pin is inserted into the inside of the through hole.

[0019] By adopting the above technical solution, after the second feeding rod is unfolded, the second locking block will be stuck under the first locking block. At this time, the pin is inserted into the through hole to lock and fix the second feeding rod, thereby improving the stability during the feeding process.

[0020] Optionally, an abutment block is fixedly connected to the left end of the lower surface of each of the two sets of second feeding rods, and the left end of the abutment block abuts against the right end of the first feeding rod.

[0021] By adopting the above technical solution, the abutment block supports the second feeding rod, further improving the stability of the second feeding rod.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0023] 1. This utility model uses a hydraulic cylinder to rotate the first and second feeding rods to an inclined position, and then rolls the two ends of the feeding roller to the upper side of the second feeding rod on both sides. At this time, the hydraulic cylinder rotates the first and second feeding rods to a horizontal position and lifts the non-woven fabric roll upward. Then, the two ends of the feeding roller are rolled to the inner side of the fixing frame for fixing, which completes the feeding of the non-woven fabric roll and improves the convenience and efficiency of feeding.

[0024] 2. This utility model rotates the second feeding rod around the first feeding rod. During the unwinding process, the second feeding rod is rotated to the side of the first feeding rod. Then, the hydraulic cylinder rotates the first feeding rod and the second feeding rod downward to a vertical position, so that they are close to the side of the equipment support, reducing the space occupied and further improving the ease of use of the equipment.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] This utility model provides, for example Figures 1 to 3The feeding mechanism for a nonwoven fabric slitting machine shown includes a device support 1. A feeding roller 15 is provided on the right side of the device support 1, and a pressure roller 19 is provided on the upper side of the feeding roller 15. A nonwoven fabric roll 2 is provided on the surface of the feeding roller 15. Fixing frames 13 are fixedly connected to both the front and rear sides of the right end of the device support 1. The upper end of the fixing frame 13 is threadedly connected to a limit screw 14. A connecting shaft 16 is fixedly connected inside the feeding roller 15. Fixed bearings 17 are rotatably connected to both ends of the connecting shaft 16. The fixed bearings 17 are locked inside the fixing frame 13. The limit screw 14 is locked on the right side of the fixed bearing 17. A servo motor 11 is fixedly installed on the front side of the right end of the device support 1. A first gear 12 is fixedly connected to the output end of the servo motor 11. A second gear 18 is fixedly connected to the front end of the connecting shaft 16. The first gear 12 and the second gear 18 are meshed together.

[0036] The nonwoven fabric roll 2 has a drum at its center. The nonwoven fabric roll 2 is wound onto the surface of the drum. The unloading roller 15 is fixed inside the drum. Then, the fixed bearings 17 on both sides are clamped inside the fixed brackets 13 on both sides. The limiting screws 14 are rotated downward to limit the fixed bearings 17 and fix them inside the fixed brackets 13. At this time, the connecting shaft 16 rotates inside the two sets of fixed bearings 17. During the unwinding process, the output end of the servo motor 11 drives the first gear 12 to rotate. The first gear 12 drives the connecting shaft 16 to rotate through the second gear 18, which in turn drives the unloading roller 15 to rotate. The unloading roller 15 drives the nonwoven fabric roll 2 to rotate and unwind the nonwoven fabric. During the unwinding process, the pressure roller 19 presses on the surface of the nonwoven fabric roll 2 to prevent the nonwoven fabric roll 2 from unwinding.

[0037] See Figure 1 , Figures 4 to 6The equipment support 1 has feeding components 3 on both the front and rear sides of the right end. Each feeding component 3 includes a first connecting block 31, a first feeding rod 32, a second feeding rod 33, a limiting rod 34, a support shaft 35, a connecting sleeve 36, a second connecting block 37, and a hydraulic cylinder 38. The two sets of first connecting blocks 31 are fixedly connected to the front and rear sides of the right end of the equipment support 1, respectively. The left end of the first feeding rod 32 is rotatably connected to the first connecting block 31, and the left end of the second feeding rod 33 is rotatably connected to the right end of the first feeding rod 32. The limiting rod 34 is fixedly connected to the right end of the second feeding rod 33. The first connecting block 31... Positioning rods 310 are fixedly connected to the upper surfaces of the first feeding rod 32 and the second feeding rod 33. The second connecting block 37 is rotatably connected to the lower end of the hydraulic cylinder 38. The second connecting block 37 is fixedly connected to the lower right end of the equipment support 1. The connecting sleeve 36 is fixedly connected to the upper end of the piston rod in the hydraulic cylinder 38. The support shaft 35 is fixedly connected to the lower right side of the first feeding rod 32. The connecting sleeve 36 is rotatably connected to the support shaft 35. The left end of the lower surface of the two sets of second feeding rods 33 is fixedly connected to the abutment block 39. The left end of the abutment block 39 abuts against the right end of the first feeding rod 32.

[0038] In addition, during the feeding process, the hydraulic cylinder 38 is first activated, and the piston rod in the hydraulic cylinder 38 is pushed outward. Through the connection sleeve 36 and the support shaft 35, the first feeding rod 32 is pushed outward, so that the first feeding rod 32 rotates around the first connecting block 31 to an inclined position. At this time, the second feeding rod 33 is unfolded outward, so that it is located at the right end of the first feeding rod 32, and the lower end of the second feeding rod 33 is close to the ground. At the same time, the feeding roller 15 is fixed inside the roll of nonwoven fabric 2. After the second feeding rod 33 is unfolded, the nonwoven fabric roll 2 is rolled between the front and rear feeding components 3, and the position of the nonwoven fabric roll 2 is adjusted so that the fixed bearings 17 at both ends are located above the second feeding rod 33. Next, the hydraulic cylinder 38 is activated again, and the hydraulic cylinder 38 continues to push the first feeding rod 32 and the second feeding rod 33 upward until the first feeding rod 32 and the second feeding rod 33 rotate to a horizontal position.

[0039] Simultaneously, as the first feeding rod 32 and the second feeding rod 33 rotate upward, the positioning rod 310 will be locked in the slot on the surface of the fixed bearing 17, and the non-woven fabric roll 2 will be lifted upward through the connecting shaft 16. After the first feeding rod 32 and the second feeding rod 33 rotate to a horizontal position, the non-woven fabric roll 2 will be rolled to the left in conjunction with the fixed bearing 17. During the rolling process, the positioning rod 310 will accurately position the fixed bearing 17 so that it can be accurately locked inside the fixed frame 13. Then, the limiting screw 14 will be rotated downward, thereby fixing the non-woven fabric roll 2 to the right end of the equipment bracket 1, which effectively improves the convenience of feeding and allows operation in a limited space, improving feeding efficiency. After feeding is completed, the first feeding rod 32 and the second feeding rod 33 will be folded back and recycled to the right end of the equipment bracket 1.

[0040] See Figure 1 and Figure 7 The right ends of the two sets of first feeding rods 32 on the side of their adjacent surfaces are fixedly connected to a first fixing block 311. The left ends of the two sets of second feeding rods 33 on the side of their adjacent surfaces are fixedly connected to a second fixing block 312. The second fixing block 312 is rotatably connected to the first fixing block 311. The right ends of the two sets of first feeding rods 32 on the side of their opposite surfaces are fixedly connected to a first locking block 313. The left ends of the two sets of second feeding rods 33 on the side of their opposite surfaces are fixedly connected to a second locking block 314. The surfaces of the second locking block 314 and the first locking block 313 are provided with through holes, and a pin 315 is inserted into the inside of the through holes.

[0041] Specifically, the second fixing block 312 rotates around the first fixing block 311, causing the second feeding rod 33 to rotate around the first feeding rod 32. After the second feeding rod 33 is unfolded to a horizontal position, the second locking block 314 will be locked inside the first locking block 313. At this time, the pin 315 is inserted into the through hole on the surface of the second locking block 314 and the first locking block 313 to lock and fix the first locking block 313 and the second locking block 314, thereby fixing the second feeding rod 33 to the right end of the first feeding rod 32 and improving the stability of the second feeding rod 33 during the feeding process.

[0042] The working principle of this utility model is as follows: The first feeding rod 32 and the second feeding rod 33 are rotated to an inclined position by the hydraulic cylinder 38. Then, the two ends of the unloading roller 15 are rolled to the upper side of the second feeding rod 33 on both sides. At this time, the hydraulic cylinder 38 rotates the first feeding rod 32 and the second feeding rod 33 to a horizontal position and lifts the non-woven fabric roll 2 upward. Then, the two ends of the unloading roller 15 are rolled to the inner side of the fixing frame 13 for fixing, thus completing the feeding of the non-woven fabric roll 2, improving the convenience and efficiency of feeding. At the same time, by rotating the second feeding rod 33 around the first feeding rod 32, the second feeding rod 33 is rotated to the side of the first feeding rod 32 during the unwinding process. Then, the hydraulic cylinder 38 rotates the first feeding rod 32 and the second feeding rod 33 downward to a vertical position, so that they are close to the side of the equipment support 1, reducing the space occupied and further improving the convenience of using the equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
