Description

Technical Field

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

[0002] The main materials of waterproof elastic nonwoven fabric include polypropylene (PP), polyester, and elastomers. Polypropylene is the main component, accounting for more than 70% of the total composition. It has good abrasion resistance and corrosion resistance, while also improving the strength and toughness of the material. Polyester accounts for about 20% of the total composition. It has excellent UV resistance and oxidation resistance, enhancing the durability and anti-aging properties of the material. Elastomers typically account for about 10% and are used to increase the elasticity and flexibility of the material.

[0003] The finished waterproof elastic nonwoven fabric will enter the winding stage, where it will be rolled into a long roll. To facilitate subsequent processing, it needs to be cut into small segments of different widths using a cutting device. However, when cutting the nonwoven fabric roll, the existing cutting device requires the user to completely disassemble and adjust the fixing bracket of the cutting blade in order to adjust the position and number of cutting blades. This causes great inconvenience to the user when cutting the nonwoven fabric roll and greatly affects work efficiency. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, this utility model proposes a non-woven fabric roll cutting device, including a horizontally arranged operating table. Two opposing supports are provided on one side of the upper surface of the operating table. The two supports are fixedly connected by a crossbar. Several fixing blocks are evenly fixed on the lower surface of the crossbar along the long side of the crossbar. Each fixing block is fixedly connected to a connecting plate by a quick-release assembly. The bottom end of the connecting plate extends out of the fixing block, and a cutting blade for cutting the non-woven fabric roll is fixed to the part of the bottom end of the connecting plate that extends out of the fixing plate.

[0005] To achieve the above objectives, the nonwoven fabric roll is placed on the operating table. The appropriate number of cutting blades is selected based on the required quantity and cutting width. The connecting plate, which is integrated with the cutting blade, is inserted into the fixing block, and the fixing block and connecting plate are fixedly connected via a quick-release assembly. The nonwoven fabric roll is then pushed towards the cutting blade to facilitate cutting. The connecting plate and fixing block are easy to assemble and disassemble, eliminating the need to completely disassemble the crossbar to remove them, thus improving work efficiency.

[0006] Furthermore, the quick-installation assembly includes a fixing slot formed on the inner wall of the fixing block and adapted to one side of the connecting plate. The outer wall of the fixing block has a square hole, and a locking block adapted to the square hole is slidably connected in the square hole. The locking block has a movable slot on the side facing the connecting plate that is adapted to the other side of the connecting plate. A first stud that is rotatably connected to the locking block passes through the locking block. The inner wall of the square hole has a first threaded hole adapted to the first stud. Both ends of the first stud protrude from the locking block. One end of the first stud that protrudes from the locking block is coaxially fixed with a handle, and the other end passes into the first threaded hole and is threadedly connected to the first threaded hole.

[0007] With the above technical solution, when installing the connecting plate, insert the connecting plate into the fixed slot and the movable slot, manually rotate the handle to drive the first stud, which is integrated with the handle, to rotate. The first stud moves in the first screw hole during rotation, which drives the locking block to move and clamp the connecting plate, effectively improving the stability of the connection between the connecting plate and the fixed block.

[0008] Furthermore, two guide posts are fixed on the card block, which are respectively located on both sides of the first stud. Two guide holes are opened in the inner wall of the square hole, which are arranged opposite to each other and adapted to the guide posts. The end of the guide post away from the card block enters the guide hole and slides and connects with the guide hole. The square hole and the card block are connected by a spring sleeved on the outside of the guide post.

[0009] The above technical solution guides and limits the movement of the locking block by means of the guide post and guide hole. By setting a spring on the outside of the guide post, the locking block can be easily ejected, thus facilitating the installation of the connecting plate.

[0010] Furthermore, a limit stop is fixed on the lower surface of the fixing block, and the limit stop abuts against the connecting plate.

[0011] By using the above technical solution, the position of the connecting plate is limited by setting a limiting block that abuts against the connecting plate, thereby further improving the stability of the connection between the connecting plate and the fixing block.

[0012] Furthermore, a support platform for supporting the nonwoven fabric roll is slidably connected to the upper surface of the operating table, and the support platform is connected to the operating table through a moving component.

[0013] With the above technical solution, the nonwoven fabric roll is placed on the support platform, and the moving component provides power to push the support platform toward the direction of the cutting blade, so as to cut the nonwoven fabric roll.

[0014] Furthermore, the movable component includes lugs fixed on both sides of the lower surface of the operating table, a screw rotatably connected between the two lugs, a motor for driving the screw to rotate fixed on one of the lugs, a movable block threadedly connected to the screw sleeve on the screw, a base plate fixed on the movable block, two opposing slide rails fixed on the lower surface of the operating table, a sliding block slidably connected on each slide rail, the side of the sliding block facing away from the slide rail fixed to the base plate, two movable holes opened on the operating table, a side plate slidably connected in each movable hole, the side plate passing through the movable hole through the operating table, the side plate extending out of the bottom end of the operating table and fixed to the base plate, and extending out of the top end of the operating table and fixed to the support platform.

[0015] The above technical solution uses a motor to provide power and drive the screw to rotate. The rotation of the screw will drive the moving block that is threadedly connected to the screw to move, which in turn drives the base plate, two side plates and support platform that are integrated with the moving block to move. The movement of the base plate is guided by the cooperation of the slide rail and the sliding block, and the movement of the side plates is guided and limited by the moving hole.

[0016] Furthermore, the support platform is provided with a number of evenly arranged second screw holes, some of which are internally threaded with second studs. The second studs extend out of the second screw holes, and the portion of the second studs extending out of the second screw holes is fixed with a baffle to limit the position of the non-woven fabric roll. The upper surface of the operating platform is provided with a number of grooves corresponding to the cutting blades, and the width of the grooves is slightly larger than the width of the cutting blades.

[0017] The above technical solution uses several baffles to fix the nonwoven fabric roll in a suitable area without affecting the movement of the cutting blade. Several grooves are provided to facilitate the cutting blade to enter the grooves and cut the nonwoven fabric roll.

[0018] In summary, the nonwoven fabric roll cutting device has the following beneficial effects:

[0019] (1) The nonwoven fabric roll cutting device places the nonwoven fabric roll on the operating table, selects an appropriate number of cutting blades according to the required quantity, inserts the connecting plate with the cutting blade integrated structure into the fixing block according to the required cutting width, and fixes the fixing block and connecting plate through the quick-release assembly. Push the nonwoven fabric roll toward the cutting blade to facilitate cutting the nonwoven fabric roll. The connecting plate and fixing block are easy to disassemble and assemble, and there is no need to disassemble the crossbar as a whole to disassemble the connecting plate and fixing block, thus improving work efficiency.

[0020] (2) The nonwoven fabric roll cutting device is powered by a motor to drive the screw to rotate. The rotation of the screw will drive the moving block connected to the screw to move, which in turn drives the base plate, two side plates and support platform integrated with the moving block to move. The movement of the base plate is guided by the cooperation of the slide rail and the sliding block, and the movement of the side plate is guided and limited by the moving hole.

[0021] (3) The non-woven fabric roll cutting device fixes the non-woven fabric roll in a suitable area by setting several baffles, without affecting the movement of the cutting knife. By setting several grooves, it is convenient for the cutting knife to enter the grooves and cut the non-woven fabric roll. Attached Figure Description

[0030] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0031] like Figure 1-6 As shown, the preferred embodiment of this utility model provides a non-woven fabric roll cutting device, including a horizontally arranged operating table 1. Two opposing supports 2 are provided on one side of the upper surface of the operating table 1. The two supports 2 are fixedly connected by a crossbar 3. Several fixing blocks 4 are evenly fixed on the lower surface of the crossbar 3 along the long side of the crossbar 3. Each fixing block 4 is fixedly connected to a connecting plate 6 by a quick-release assembly 5. The bottom end of the connecting plate 6 extends out of the fixing block 4. A cutting blade 7 for cutting the non-woven fabric roll is fixed to the part of the bottom end of the connecting plate 6 that extends out of the fixing plate.

[0032] like Figure 1 and Figure 2 and Figure 3 The non-woven fabric roll is placed on the operating table 1. The appropriate number of cutting blades 7 are selected based on the required quantity to be cut. The connecting plate 6, which is integrated with the cutting blade 7, is inserted into the fixing block 4, and the fixing block 4 and connecting plate 6 are fixedly connected by the quick-release assembly 5. The non-woven fabric roll is pushed towards the cutting blade 7 to facilitate cutting. The connecting plate 6 and fixing block 4 are easy to assemble and disassemble, eliminating the need to completely disassemble the crossbar 3 to remove the connecting plate 6 and fixing block 4, thus improving work efficiency.

[0033] like Figure 4 and Figure 5 and Figure 6 The quick-install component 5 includes a fixing slot 501 formed on the inner wall of the fixing block 4 and adapted to one side of the connecting plate 6. A square hole 502 is formed on the outer wall of the fixing block 4. A locking block 503 adapted to the square hole 502 is slidably connected in the square hole 502. A movable slot 504 adapted to the other side of the connecting plate 6 is formed on the side of the locking block 503 facing the connecting plate 6. A first stud 505 rotatably connected to the locking block 503 passes through the locking block 503. A first screw hole adapted to the first stud 505 is formed in the inner wall of the square hole 502. Both ends of the first stud 505 protrude from the locking block 503. A handle 506 is coaxially fixed at one end of the first stud 505 protruding from the locking block 503, and the other end is inserted into the first screw hole and threadedly connected to the first screw hole.

[0034] like Figure 4 and Figure 5 and Figure 6 When installing the connecting plate 6, insert the connecting plate 6 into the fixed slot 501 and the movable slot 504, manually rotate the handle 506 to drive the first stud 505, which is integrated with the handle 506, to rotate. The first stud 505 moves in the first screw hole during rotation, which drives the locking block 503 to move and clamp the connecting plate 6, effectively improving the stability of the connection between the connecting plate 6 and the fixed block 4.

[0035] like Figure 4 and Figure 5 and Figure 6Two guide posts 507 are fixed on the locking block 503, which are arranged opposite to each other. The two guide posts 507 are located on both sides of the first stud 505. Two guide holes 508 are opened on the inner wall of the square hole 502, which are arranged opposite to each other and adapted to the guide posts 507. The end of the guide post 507 away from the locking block 503 enters the guide hole 508 and slides and connects with the guide hole 508. The square hole 502 and the locking block 503 are connected by a spring 509 sleeved on the guide post 507.

[0036] like Figure 4 and Figure 5 and Figure 6 The guide post 507 and the guide hole 508 work together to guide and limit the movement of the locking block 503. A spring 509 is set outside the guide post 507 to facilitate the pop-out of the locking block 503, thereby facilitating the installation of the connecting plate 6. A sliding hole is provided in the inner wall of the guide hole 508. A raised slider is slidably connected in the sliding hole. The raised slider extends out of the sliding hole and enters the guide hole 508. The part of the raised slider that enters the guide hole 508 is fixed to the guide post 507. The cooperation between the sliding hole and the raised slider prevents the locking block 503 from detaching from the fixing block 4.

[0037] like Figure 4 and Figure 5 and Figure 6 A limit stop 8 is fixed on the lower surface of the fixing block 4. The limit stop 8 abuts against the connecting plate 6. By setting the limit stop 8 that abuts against the connecting plate 6, the position of the connecting plate 6 is limited, thereby further improving the stability of the connection between the connecting plate 6 and the fixing block 4.

[0038] like Figure 1 and Figure 2 and Figure 3 The upper surface of the operating table 1 is slidably connected to a support platform 9 that supports the nonwoven fabric roll. The support platform 9 is connected to the operating table 1 via a moving component 10. The nonwoven fabric roll is placed on the support platform 9. The moving component 10 provides power to push the support platform 9 toward the cutting blade 7 so as to cut the nonwoven fabric roll.

[0039] like Figure 1 and Figure 2 and Figure 3The movable component 10 includes ear seats 1001 fixed on both sides of the lower surface of the operating table 1. A screw 1002 is rotatably connected between the two ear seats 1001. A motor 1003 that drives the screw 1002 to rotate is fixed on one of the ear seats 1001. A movable block 1004 that is threadedly connected to the screw 1002 is sleeved on the screw 1002. A base plate 1005 is fixed on the movable block 1004. Two oppositely arranged slide rails are fixed on the lower surface of the operating table 1. 1006, each slide rail 1006 is slidably connected to a sliding block, the side of the sliding block away from the slide rail 1006 is fixed to the base plate 1005, the operating table 1 is provided with two moving holes 1007, each moving hole 1007 is slidably connected to a side plate 1008, the side plate 1008 passes through the moving hole 1007 through the operating table 1, the side plate 1008 passes through the bottom end of the operating table 1 and is fixed to the base plate 1005, and passes through the top end of the operating table 1 and is fixed to the support platform 9.

[0040] like Figure 1 and Figure 2 and Figure 3 The motor 1003 provides power to drive the screw 1002 to rotate. The rotation of the screw 1002 will drive the moving block 1004, which is threadedly connected to the screw 1002, to move. This, in turn, will drive the base plate 1005, the two side plates 1008, and the support platform 9, which are integrated with the moving block 1004, to move. The movement of the base plate 1005 is guided by the cooperation of the slide rail 1006 and the sliding block. The movement of the side plate 1008 is guided and limited by the moving hole 1007.

[0041] like Figure 1 and Figure 2 and Figure 3 The support platform 9 has several evenly arranged second screw holes, some of which are internally threaded with second studs. The second studs extend out of the second screw holes, and the portion of the second studs extending out of the second screw holes is fixed with a baffle 11 to limit the movement of the non-woven fabric roll. The upper surface of the operating table 1 has several grooves 12 that correspond one-to-one with the cutting blade 7. The width of the grooves 12 is slightly larger than the width of the cutting blade 7. By setting several baffles 11, the non-woven fabric roll is fixed in a suitable area without affecting the movement of the cutting blade 7. By setting several grooves 12, it is convenient for the cutting blade 7 to enter the grooves 12 and cut the non-woven fabric roll.

[0042] When in use, connect the power supply and turn on the switch. The staff places the non-woven fabric roll on the support platform 9. According to the size of the non-woven fabric roll, select an appropriate number of baffles 11, and make the second stud with the baffle 11 integrated structure inserted into the appropriate second screw hole and threadedly fixed with the second screw hole. The non-woven fabric roll is fixed and limited by several baffles 11, and the baffles 11 do not affect the cutting of the cutting blade 7.

[0043] According to the number of non-woven fabric rolls to be cut, the worker inserts the connecting plate 6, which is fixed to the cutting blade 7, into the appropriate fixing block 4, so that the two sides of the connecting plate 6 are inserted into the fixing slot 501 and the movable slot 504. The worker manually rotates the handle 506, which drives the first stud 505, which is integrated with the handle 506, to rotate. The first stud 505 moves in the first screw hole during rotation, which drives the clamping block 503 to move and clamp the connecting plate 6. At this time, the spring 509 is compressed. Through the cooperation of the guide post 507 and the guide hole 508, the movement of the clamping block 503 is guided and limited.

[0044] Then, the motor 1003 is turned on, providing power to rotate the screw 1002. The rotation of the screw 1002 will drive the moving block 1004, which is threadedly connected to the screw 1002, to move. This, in turn, will drive the base plate 1005, the two side plates 1008, and the support platform 9, which are integrated with the moving block 1004, to move. The sliding rail 1006 and the sliding block guide the movement of the base plate 1005. The moving hole 1007 guides and limits the movement of the side plates 1008. The movement of the support platform 9 will drive the non-woven fabric roll on the support platform 9 to move towards the cutting blade 7, thus cutting the non-woven fabric roll. If the cutting blade 7 is not stable enough, the operator can attach a long rod higher than the non-woven fabric roll to several cutting blades 7. The long rod has a slot adapted to the cutting blade 7. The long rod is inserted and fixed to the cutting blade 7. The two ends of the long rod are fixed to the bracket 2 with screws to improve the stability of the cutting blade 7.
