Technical Field

[0001] This utility model relates to the field of aluminum-coated film woven fabric production technology, and in particular to a cutting device for the production of aluminum-coated film woven fabric. Background Technology

[0002] Metallized film woven fabric is a new type of material made by combining metallized film and woven fabric through a composite process. It combines the light-blocking, moisture-proof, and barrier properties of metallized film with the high strength and tear resistance of woven fabric, and is widely used in packaging, building materials, and agricultural covering. During its production and processing, wide rolls need to be slit into narrow strips of different widths or cut into sheets of fixed lengths according to downstream application requirements. Therefore, the slitting mechanism is the core component of the cutting device, and its performance directly affects the product specification accuracy and processing efficiency.

[0003] The existing cutting mechanism of aluminized film woven fabric cutting device has obvious limitations in terms of the adjustment of the circular cutter: the circular cutter mostly adopts fixed installation or single axis limiting structure, such as positioning by whole shaft sleeve or fixing by welding the cutter seat. When adjusting the cutting width, the cutter shaft needs to be completely disassembled and the limiting parts of different thicknesses need to be replaced. The operation is cumbersome and time-consuming, and it is difficult to adapt to the rapid switching of multiple specifications of products. It is inconvenient to use and has poor practicality.

The cutting mechanism includes a hydraulic cylinder three, which is symmetrically arranged on the top of the support. The telescopic end of the hydraulic cylinder three is connected to a blade holder two inside the support. A cutting blade is detachably installed on the inner side of the blade holder two.

[0006] As a preferred embodiment, the slitting mechanism further includes a limiting plate, which is sleeved on the outside of the limiting shaft, and the lower end of the limiting plate covers the outside of the circular cutter. The limiting shaft is fixedly connected to the cutter holder. A cavity is formed inside the limiting plate corresponding to the limiting shaft. A guide rod is provided on one side of the limiting shaft inside the cavity. A slidingly connected locking rod is symmetrically sleeved on the outer wall of the guide rod. Several locking grooves adapted to the locking rods are symmetrically formed on the outer wall of the limiting shaft. A spring is symmetrically sleeved on the outer side of the guide rod opposite to the locking rod. A push rod is provided between the locking rods on one side of the limiting shaft, and one end of the push rod extends outside the limiting plate. The other end of the push rod is connected to a support rod. Guide wheels are rotatably connected to both ends of the support rod. Guide blocks adapted to the guide wheels are symmetrically provided on the inner walls of the locking rods, and the guide blocks are right-angled trapezoidal structures. A spring is sleeved on the outer side of the push rod inside the cavity, and the two ends of the spring are fixedly connected to the support rod and the inner wall of the cavity, respectively.

[0007] As a preferred embodiment, the inclined wall at one end of the guide block is provided with a groove adapted to the guide wheel, the limiting plate is an inverted U-shaped structure, and several rotatable balls are embedded in symmetrical positions on the inner wall of the limiting plate, with the outer wall of the balls contacting the outer wall of the circular cutter, and the transmission sleeve is slidably connected to the drive shaft.

[0008] As a preferred embodiment, the tool holder includes an L-shaped frame and a support plate. The support plate is located inside the L-shaped frame and has a locking block connected to its top. One end of the horizontal portion of the L-shaped frame has an installation groove that matches the locking block. The top of the L-shaped frame is threaded with a quick-release bolt, and the lower end of the quick-release bolt is threaded to the locking block. The side wall of the support plate has a through hole one and a through hole two that match the drive shaft and the limit shaft, respectively.

[0009] As a preferred embodiment, the cutting mechanism further includes a fixing block, which is rectangularly distributed on both sides of the blade holder.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects: 1. This utility model's slitting mechanism uses a hydraulic cylinder to drive several circular cutters downwards, which in turn are rotated by a motor to slit aluminized film woven bags. During adjustment, pushing the push rod moves the support rod, which, via guide wheels and guide blocks, moves the locking rod out of the slot, releasing the limiting plate. Dragging the limiting plate allows the circular cutters and transmission sleeve to slide on the drive shaft, adjusting the distance between adjacent circular cutters to change the slitting width. After adjustment, releasing the push rod causes the locking rod and push rod to reset under the force of springs one and two, and the locking rod engages in the slot for fixation. This allows for quick and easy adjustment and fixation of the circular cutter position, making operation convenient and efficient, and enhancing practicality.

[0012] 2. This utility model reduces friction between the circular cutter and the limiting plate by using ball bearings, thus reducing power loss. The cutter holder, composed of an L-frame, support plate, locking block, and quick-release bolts, facilitates the later assembly and disassembly of the circular cutter and the limiting plate, as well as the addition or reduction of their number.

[0013] 3. This utility model can cut the slit aluminum-coated woven bags to a suitable length through a cutting mechanism, and can also press the woven bags below with pressure rollers during the cutting operation to prevent them from moving during the cutting process and affecting the cutting quality.

Detailed Implementation

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Reference Figures 1-6 As shown, a cutting device for producing aluminized film woven fabric is provided, including a frame 1, a support 2 on the top of the frame 1, two guide rollers 3 rotatably mounted on the inner side of one end of the support 2, two sets of guiding components on the inner side of the support 2 near the guide rollers 3, and a slitting mechanism and a cutting mechanism respectively on the left and right sides of the support 2 away from the guide rollers 3; providing a stable installation foundation for the entire device, ensuring that each mechanism remains stable during operation, and ensuring the orderly progress of the aluminized film woven fabric processing flow; The slitting mechanism includes a second hydraulic cylinder 7, which is symmetrically arranged on the top of the support 2. The telescopic end of the second hydraulic cylinder 7 is connected to a first blade holder 8 inside the support 2. The first blade holder 8 is provided with a drive shaft 13 and a limit shaft 14 arranged vertically inside. One end of the drive shaft 13 is connected to a motor 15 on one side of the first blade holder 8. Several transmission sleeves 19 are sleeved on the outside of the drive shaft 13, and circular cutters 9 are provided on the outer wall of the transmission sleeves 19. The extension and retraction of the second hydraulic cylinder 7 drives the first blade holder 8 to move up and down, and the motor 15 drives the drive shaft 13 and the circular cutters 9 to rotate, which can realize the efficient slitting of the aluminized film woven fabric. The arrangement of multiple circular cutters 9 can meet the slitting requirements of different widths. The cutting mechanism includes a hydraulic cylinder 310, which is symmetrically arranged on the top of the bracket 2. The telescopic end of the hydraulic cylinder 310 is connected to a knife holder 21 inside the bracket 2. A cutting shear 12 is detachably installed inside the knife holder 21. The hydraulic cylinder 310 drives the knife holder 21 and the cutting shear 12 to move up and down, which can complete the fixed-length cutting of the slit aluminum-coated woven fabric. The detachable design of the cutting shear 12 facilitates later replacement and maintenance.

[0018] In this example, the slitting mechanism also includes a limiting plate 20, which is sleeved on the outside of the limiting shaft 14, and the lower end of the limiting plate 20 covers the outside of the circular cutter 9. The limiting shaft 14 is fixedly connected to the cutter holder 8. A cavity 21 is formed inside the limiting plate 20 corresponding to the limiting shaft 14. A guide rod 22 is provided on one side of the limiting shaft 14 inside the cavity 21. A slidingly connected locking rod 23 is symmetrically sleeved on the outer wall of the guide rod 22. Several locking grooves 30 adapted to the locking rods 23 are symmetrically formed on the outer wall of the limiting shaft 14. A spring 24 is symmetrically sleeved on the outer side of the guide rod 22 opposite to the outer side of the locking rod 23. A push rod 25 is provided between the locking rods 23 on one side of the limiting shaft 14. One end of the push rod 25 extends to the outside of the limiting plate 20, and the other end of the push rod 25 is connected to the support rod 26. Both ends of the support rod 26 are rotatably connected to the guide wheels 27. The clamping rod 23 is symmetrically provided with guide blocks 28 that are adapted to the guide wheels 27 on the inner wall. The guide blocks 28 are right-angled trapezoidal structures. The outer side of the push rod 25 is fitted with a spring 29 inside the cavity 21, and both ends of the spring 29 are fixedly connected to the support rod 26 and the inner wall of the cavity 21, respectively. By pushing the push rod 25 to drive the transmission of related components, the limiting plate 20 can be easily released, and the position of the circular cutter 9 can be flexibly adjusted. After adjustment, it can be quickly fixed under the action of the spring. The operation is simple and the efficiency of the cutting width adjustment is greatly improved.

[0019] In this example, the inclined wall at one end of the guide block 28 is provided with a groove that matches the guide wheel 27. The limiting plate 20 has an inverted U-shaped structure. Several rotatable balls 31 are embedded in symmetrical positions on the inner wall of the limiting plate 20, and the outer wall of the balls 31 contacts the outer wall of the circular cutter 9. The transmission sleeve 19 is slidably connected to the drive shaft 13. The setting of the balls 31 can effectively reduce the friction between the circular cutter 9 and the limiting plate 20, reduce power loss, and at the same time ensure that the circular cutter 9 rotates smoothly and improves the cutting stability.

[0020] In this example, the tool holder 8 includes an L-frame 38 and a support plate 16. The support plate 16 is located inside the L-frame 38. A locking block 17 is connected to the top of the support plate 16. One end of the horizontal part of the L-frame 38 has an installation groove that matches the locking block 17. A quick-release bolt 18 is threadedly connected to the top of the L-frame 38, and the lower end of the quick-release bolt 18 is threadedly connected to the locking block 17. The side wall of the support plate 16 has a through hole 1 and a through hole 2 that match the drive shaft 13 and the limiting shaft 14, respectively. The tool holder 8 structure, composed of quick-release bolts 18, facilitates quick disassembly and assembly, and allows for the addition or removal of the circular cutter 9 and the limiting plate 20. It can flexibly adapt to different slitting requirements and reduce maintenance difficulty.

[0021] In this example, the cutting mechanism also includes a fixing block 32, which is rectangularly distributed on both sides of the blade holder 11. A connecting rod 33 is provided above the fixing block 32, and a stop block 34 is connected to the upper end of the connecting rod 33. A spring 35 is sleeved on the outside of the connecting rod 33 between the stop block 34 and the fixing block 32, and the two ends of the spring 35 are fixedly connected to the stop block 34 and the fixing block 32 respectively. The lower ends of the connecting rod 33 on the same side of the blade holder 11 are connected to a fixing frame 36, and a pressure roller 37 is rotatably installed in the fixing frame 36. During cutting, the pressure roller 37 can tightly press the material under the action of the spring, effectively preventing the material from moving, ensuring neat cutting edges, and improving cutting quality.

[0022] In this example, the guiding component includes a hydraulic cylinder 4, which is symmetrically arranged on the top of the bracket 2 near the guide roller 3. The telescopic end of the hydraulic cylinder 4 is connected to a U-shaped frame 5 inside the bracket 2. A rotating roller 6 is rotatably installed inside the U-shaped frame 5. The height of the rotating roller 6 can be adjusted by the hydraulic cylinder 4, which can adjust the tension of the aluminized film woven fabric. The rotating roller 6 can guide the material to be transported smoothly, ensuring high precision for subsequent slitting and cutting.

[0023] During use, in the material introduction and guiding stage: after the aluminized film woven fabric roll is unwound, it first enters the guide roller 3 on the frame 1. The guide roller 3 rotates to guide the initial material conveying; then the material enters the guiding assembly, and the hydraulic cylinder 4 extends and retracts to drive the U-shaped frame 5 and the rotating roller 6 to move up and down, adjusting the fit between the rotating roller 6 and the material. The rotating roller 6 rotates synchronously with the material conveying to ensure that the material moves flat and stably towards the slitting mechanism and the cutting mechanism. The height position of the rotating roller 6 in the two sets of guiding assemblies can be adjusted as needed to adjust the tension of the aluminized film woven fabric. Cutting preparation and position adjustment stage: According to the required cutting width, the operator pushes the push rod 25 in the cutting mechanism, the support rod 26 drives the guide wheel 27 to move, the guide wheel 27 squeezes the guide block 28 to make the locking rod 23 slide outward along the guide rod 22 and compress the first spring 24. The locking rod 23 disengages from the slot 30 of the limiting shaft 14. At this time, the limiting plate 20 can be pushed to drive the transmission sleeve 19 and the circular cutter 9 to slide on the drive shaft 13 to adjust the distance between adjacent circular cutters 9. After the adjustment is completed, the push rod 25 is released. Under the action of the restoring force of the first spring 24 and the second spring 29, the locking rod 23 is locked into the corresponding slot 30, the guide wheel 27 and the push rod 25 are reset, and the position of the circular cutter 9 is fixed. During the slitting process: When slitting, the extension end of the hydraulic cylinder 2 7 extends, causing the blade holder 1 8 to move downward, so that the circular cutter 9 contacts the material surface; at the same time, the motor 15 starts and drives the drive shaft 13 to rotate, and the transmission sleeve 19 drives the circular cutter 9 to rotate synchronously, performing longitudinal slitting on the material; during the slitting process, the ball bearings 31 on the inner wall of the limiting plate 20 contact and roll with the circular cutter 9, reducing frictional resistance.

[0024] Cutting preparation and pressing stage: The cut material continues to be conveyed to the lower part of the cutting mechanism. When the set cutting length is reached, the extension end of the hydraulic cylinder 310 extends, driving the blade holder 21 and the cutting blade 12 to move down. During the downward movement, the pressure rollers 37 on both sides of the blade holder 21 contact the material before the cutting blade 12. As the blade holder 21 continues to move down, the connecting rod 33 drives the stop block 34 to move up and stretch the spring 35. The elastic force of the spring 35 makes the pressure rollers 37 press the material tightly. Cutting execution and reset stage: The cutting blade 12 continues to move down with the blade holder 2 11 to cut the pressed material laterally; after the cutting is completed, the extension end of the hydraulic cylinder 3 10 retracts, driving the blade holder 2 11 to move up, and the force on the spring 3 35 gradually decreases until the pressure roller 37 and the cutting blade 12 are completely separated from the material, completing one cutting and slitting cycle. Tool holder maintenance and cutter addition / reduction stage: When it is necessary to maintain or replace the circular cutter 9 and the limiting plate 20, loosen the quick-release bolt 18 on the tool holder 8, separate the locking block 17 between the L frame 38 and the support plate 16, and then follow the steps for adjusting the position of the circular cutter 9 to release the limiting plate 20 and the limiting shaft 14, and then remove the relevant parts on the drive shaft 13 and the limiting shaft 14; when increasing or decreasing the number of circular cutters 9 according to production needs, disassemble and reassemble according to the same steps, and then re-fix the support plate 16 after adjustment.
