Description

Technical Field

[0001] This invention belongs to the field of fireworks processing technology, specifically a swing cutting device for fireworks tube paper. Background Technology

[0002] The inner tube of fireworks is a crucial component of combination fireworks. During production, specially made paper needs to be punched into circular pieces that match the diameter of the inner tube, used for sealing or partitioning. Currently, the punching process for the inner tube paper primarily utilizes fixed punching equipment. A paper feeding mechanism delivers the paper to the punching station, where punching dies are arranged in a fixed array to punch the paper in one pass. While this type of equipment enables automated continuous production, the fixed and uniform arrangement of the punching holes on the paper, requiring sufficient spacing between adjacent holes to prevent tearing or deformation during the punching process, results in a large amount of unused area on the paper, leading to significant material waste. Furthermore, existing equipment lacks methods to optimize the paper punching arrangement, making it difficult to arrange more holes within a limited paper area, resulting in low paper utilization efficiency and increased production costs.

[0003] Therefore, this application provides a oscillating cutting device for fireworks tube paper. By driving the paper to oscillate laterally during the punching process, the punching holes are arranged in an alternating pattern on the paper, thereby arranging more holes on the same paper area, effectively improving paper utilization efficiency and reducing material costs. Summary of the Invention

[0004] To address the above problems, this invention provides a firework tube paper swing cutting device, which solves the problems of how to coordinate the multi-directional movement of paper during cutting and the low paper utilization efficiency.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A oscillating cutting device for fireworks tube paper includes a punching mechanism and a front paper moving mechanism and a rear paper moving mechanism located at both ends of the punching mechanism; The front-end paper-moving mechanism is equipped with a paper-feeding roller for driving the paper. The two ends of the paper-feeding roller are movably mounted on the paper-feeding rotating seat and are driven to rotate by the paper-feeding motor. The bottom of the paper-feeding roller is fixedly mounted on the front-end paper-moving slide. The front-end paper-moving slide is driven by the front-end transverse cylinder and is slidably connected to the front-end paper-moving base fixedly mounted on the frame. The rear paper-moving mechanism includes a rear paper-moving base fixedly mounted on the frame. The rear paper-moving base has a left push plate and a right push plate respectively on both sides of the paper. The left push plate is driven to move by a rear transverse cylinder, and the right push plate is driven to move by a rear transverse cylinder. The direction in which the rear paper-moving mechanism pushes the paper is the same as the direction in which the front paper-moving mechanism pushes the paper. The punching mechanism includes a punching rod assembly located above the paper and a punching die located below the paper. The paper passes through a punching platform located between the punching rod assembly and the punching die. The punching rod assembly is mounted on a punching top seat, which is driven by a lower punch cylinder to move up and down. The lower punch cylinder is mounted on a positioning base, which is driven by a positioning guide cylinder to move up and down. The punching die is mounted on a punching base, which is driven by an upper push motor to move up and down. The punching platform, positioning guide cylinder, and top motor in the punching mechanism are all fixedly mounted on the frame; the front paper transfer base and the rear paper transfer base are also fixedly mounted on the frame. After the front transverse cylinder, rear transverse cylinder one, and rear transverse cylinder two complete the synchronous transverse movement of the paper, the paper feeding motor drives the paper feeding roller to move the paper forward a certain distance. Then, the paper cutting mechanism completes the positioning and cutting of the paper. The above three steps of synchronous transverse movement, paper forward movement, and positioning and cutting are repeated in sequence to achieve staggered cutting of the paper.

[0006] As a further improvement to the above solution, the front paper-moving slide is connected to the telescopic end of the front transverse cylinder via a connector, and the front transverse cylinder is fixedly mounted on the front paper-moving base; the rear transverse cylinder one and the rear transverse cylinder two are fixedly mounted on the rear paper-moving base.

[0007] As a further improvement to the above solution, the die-cutting platform is provided with baffles on both sides of the paper to limit its lateral movement range. The die-cutting platform is fixedly provided with a positioning die-cutting hole plate with positioning calibration function above the paper. The two ends of the positioning die-cutting hole plate are fixedly connected to the upper part of the baffles on both sides. The positioning die-cutting hole plate, the baffles on both sides and the die-cutting platform at the bottom together form a paper passage that can accommodate the paper in the middle.

[0008] As a further improvement to the above solution, the blanking base is also provided with a clamping component for quick fixing and disassembly of the punching die; one side of the clamping component is fixedly connected to the blanking base, and the other side is a clamping end in a semi-enclosed shape. The tail of the clamping end is driven by a clamping cylinder to clamp and fix the punching die in the middle. The clamping cylinder is fixedly connected to the blanking base.

[0009] As a further improvement to the above solution, the semi-enclosed shape of the clamping end is a U-shaped or C-shaped structure, and the inner wall of the clamping end is provided with anti-slip texture.

[0010] As a further improvement to the above solution, the paper feeding roller includes an upper roller and a lower roller mounted on a paper feeding rotating seat. The lower roller shaft is connected to the paper feeding rotating seat through a bearing. An upper roller shaft is provided in the middle of the upper roller. The upper roller rotates around the upper roller shaft. The two ends of the upper roller shaft are slidably disposed on the paper feeding rotating seat, and a compression spring is provided between them.

[0011] As a further improvement to the above solution, one end of the lower roller shaft passes through the paper feeding rotating seat and is connected to the paper feeding motor via a coupling.

[0012] As a further improvement to the above solution, a guide plate is provided at the feeding end of the rear paper transfer base, and an upper cover plate is provided on the rear side of the guide plate, forming a paper pressing channel between the upper cover plate and the rear paper transfer base.

[0013] As a further improvement to the above solution, a guide post is provided between the blanking top seat and the positioning base, and the blanking top seat slides up and down along the guide post.

[0014] As a further improvement to the above solution, the positioning punching plate is provided with a punching guide hole corresponding to the position of the punching rod assembly, and the diameter of the punching guide hole is adapted to the outer diameter of the punching rod in the punching rod assembly.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention achieves synchronous lateral oscillation of the paper during the punching process by setting a front paper-moving mechanism and a rear paper-moving mechanism at both ends of the punching mechanism, and keeping the direction of the paper movement consistent between the two. At the same time, with the three-step cycle working mode of "synchronous lateral movement - paper forward movement - positioning punching", the punching holes are arranged in an alternating pattern on the paper, and more holes can be arranged on the same paper area, which effectively improves the material utilization rate of the paper and reduces the production cost. This invention establishes a paper feeding channel on the die-cutting platform by setting a positioning die-cutting hole plate, side baffles, and a bottom die-cutting platform together, thereby limiting and guiding the paper in all directions. At the same time, the positioning die-cutting hole plate has die-cutting guide holes corresponding to the positions of the die-cutting rods, which accurately guide the downward punching action of the die-cutting rods, effectively avoiding die-cutting deviations caused by paper offset or die-cutting rod sway during the die-cutting process, and significantly improving die-cutting accuracy and product consistency. This invention achieves rapid fixing and disassembly of punching dies by setting a semi-enclosed clamping end fixture driven by a clamping cylinder on the punching base. The clamping end has a U-shaped or C-shaped structure and the inner wall is provided with anti-slip texture, ensuring that the punching die does not shift or vibrate during the punching process. This not only improves the die changing efficiency, but also ensures the die positioning accuracy and punching stability when punching paper sheets of different specifications, and greatly enhances the process adaptability of the equipment. This invention utilizes the synchronous drive of the front transverse cylinder, the rear transverse cylinder one, and the rear transverse cylinder two, along with the timed coordinated action of the paper feeding motor and the punching mechanism, to ensure that the transverse oscillation, longitudinal feeding, and punching action of the paper are sequentially and orderly connected and closely coordinated, forming an efficient and stable automated cyclic punching operation. The actions of each mechanism do not interfere with each other and the positioning is precise, effectively avoiding paper skewing, wrinkling, or punching position deviation caused by disordered actions, thus significantly improving production efficiency and product yield.

[0021] The invention will now be further described with reference to the accompanying drawings.

[0022] like Figures 1-4As shown, a firework tube paper swing cutting device includes a punching mechanism 4 and a front paper-moving mechanism 1 and a rear paper-moving mechanism 2 located at opposite ends of the punching mechanism 4. A frame 5 serves as the mounting base for the entire device. The punching platform 410, positioning guide cylinder 46, and top motor 48 in the punching mechanism 4 are all fixedly mounted on the frame 5. The front paper-moving base 11 and the rear paper-moving base 21 are also fixedly mounted on the frame 5. The paper 3 is introduced by the front paper-moving mechanism 1, passes sequentially through the rear paper-moving mechanism 2 and the punching mechanism 4, and is punched at the punching mechanism 4 before being output from the discharge end.

[0023] I. The specific structure and working method of the front-end paper transfer mechanism; like Figures 1-4 As shown, the front-end paper-moving mechanism 1 is equipped with a paper feed roller for driving the paper. The two ends of the paper feed roller are movably mounted on the paper feed rotating seat 13 and are driven to rotate by the paper feed motor 143. The bottom of the paper feed roller is fixedly mounted on the front-end paper-moving slide 12, which is driven by the front-end transverse cylinder 190 and slidably connected to the front-end paper-moving base 11 fixedly mounted on the frame 5. Specifically, the front-end paper-moving base 11 is equipped with a slide rail, and the bottom of the front-end paper-moving slide 12 is equipped with a slider that cooperates with the slide rail, thereby achieving a sliding connection. The front-end paper-moving slide 12 is connected to the telescopic end of the front-end transverse cylinder 190 via a connector 18, and the front-end transverse cylinder 190 is fixedly mounted on the front-end paper-moving base 11.

[0024] As shown in the figure - Figure 4 As shown, the paper feeding roller includes an upper roller 15 and a lower roller 14 mounted on a paper feeding rotating base 13. The lower roller shaft of the lower roller 14 is connected to the paper feeding rotating base 13 via a bearing 141, and one end of the lower roller shaft passes through the paper feeding rotating base 13 and is connected to the paper feeding motor 143 via a coupling 142. An upper roller shaft 151 is provided in the middle of the upper roller 15, and the upper roller 15 rotates around the upper roller shaft 151. The two ends of the upper roller shaft 151 are slidably arranged with the paper feeding rotating base 13, and a compression spring 152 is provided between them. The function of the compression spring 152 is to enable the upper roller 15 to automatically adjust the gap between itself and the lower roller 14 according to the thickness of the paper 3, ensuring that a stable clamping force and conveying force can be provided for paper of different thicknesses.

[0025] During operation, the paper 3 passes between the upper roller 15 and the lower roller 14, and is clamped between them by the elastic force of the compression spring 152. After the paper feeding motor 143 starts, it drives the lower roller 14 to rotate through the coupling 142. The lower roller 14 moves the paper 3 forward by means of friction. When the paper 3 needs to swing laterally, the front transverse cylinder 190 is activated. Its telescopic end pushes the front paper transfer slide 12 to slide laterally along the slide rail on the front paper transfer base 11 through the connector 18, thereby driving the entire paper feeding roller and the paper 3 to move laterally together.

[0026] II. The specific structure and working method of the rear paper transfer mechanism; like Figures 1-4 As shown, the rear paper-moving mechanism 2 includes a rear paper-moving base 21 fixedly mounted on the frame 5. The rear paper-moving base 21 has a left push plate 24 and a right push plate 25 on either side of the paper 3. The left push plate 24 is driven to move by a rear transverse movement cylinder 26, and the right push plate 25 is driven to move by a rear transverse movement cylinder 27. The rear transverse movement cylinders 26 and 27 are fixedly mounted on the rear paper-moving base 21. The direction in which the rear paper-moving mechanism 2 pushes the paper 3 is the same as the direction in which the front paper-moving mechanism 1 pushes the paper 3; that is, the two work together to achieve the transverse swing of the paper 3.

[0027] A guide plate (not shown in the figure) is provided at the feed end of the rear paper transfer base 21 to guide the paper 3 smoothly into the rear paper transfer mechanism 2. An upper cover plate 23 is provided behind the guide plate, and a paper pressing channel is formed between the upper cover plate 23 and the rear paper transfer base 21. The paper 3 passes through the paper pressing channel and is restricted to vertical displacement, ensuring that the paper 3 runs smoothly and does not warp in the rear paper transfer mechanism 2.

[0028] During operation, when the paper 3 needs to swing laterally, the rear transverse cylinder 26 drives the left push plate 24 to push the paper 3 to the right, and the rear transverse cylinder 27 drives the right push plate 25 to push the paper 3 to the left. The left push plate 24 and the right push plate 25 apply pushing force from both sides of the paper 3, thereby realizing the lateral movement of the paper 3. Since the rear transverse cylinder 26 and the rear transverse cylinder 27 are controlled independently, the lateral displacement of the paper 3 can be precisely adjusted.

[0029] III. The specific structure and working method of the blanking mechanism; like Figures 1-4 As shown, the punching mechanism 4 includes a punching rod assembly 41 located above the paper 3 and a punching die 42 located below the paper 3. The paper 3 passes through a punching platform 410 located between the punching rod assembly 41 and the punching die 42. The punching rod assembly 41 is mounted on a punching top seat 43, which is driven by a lower punch cylinder 44 to move up and down. The lower punch cylinder 44 is mounted on a positioning base 45, which is driven by a positioning guide cylinder 46 to move up and down. A guide post 414 is provided between the punching top seat 43 and the positioning base 45. The punching top seat 43 slides up and down along the guide post 414 to ensure the verticality and positional accuracy of the punching rod assembly 41 during the punching motion. The punching die 42 is mounted on a punching base 47, which is driven by an upper push motor 48 to move up and down. Both the positioning guide cylinder 46 and the upper push motor 48 are fixedly mounted on the frame 5.

[0030] As shown in the figure - Figure 4As shown, the die-cutting platform 410 has baffles 411 on both sides of the paper 3 to limit its lateral movement range. A positioning die-cutting hole plate 412 with positioning and calibration function is fixedly installed above the paper 3 on the die-cutting platform 410. The two ends of the positioning die-cutting hole plate 412 are fixedly connected to the upper parts of the baffles 411 on both sides. The positioning die-cutting hole plate 412, the baffles 411 on both sides, and the die-cutting platform 410 at the bottom together form a paper passage 413 that can accommodate the paper 3 in the middle. The paper 3 passes through the paper passage 413 and is limited vertically by the positioning die-cutting hole plate 412 and the die-cutting platform 410, and horizontally by the baffles 411 on both sides, thereby ensuring that the position of the paper 3 at the die-cutting station is accurate and stable.

[0031] The positioning punching plate 412 has punching guide holes 415 corresponding to the positions of the punching rod assembly 41. The diameter of the punching guide holes 415 is adapted to the outer diameter of the punch rods in the punching rod assembly 41. When the punching rod assembly 41 punches downwards, the punch rods pass through the corresponding punching guide holes 415, which accurately guides the downward punching action of the punch rods. At the same time, the hole wall of the punching guide holes 415 forms a local pressure on the paper 3 around the punching point, preventing the paper 3 from shifting or wrinkling during punching.

[0032] As shown in the figure - Figure 4 As shown, the blanking base 47 is also equipped with a clamping component 49 for quickly fixing and disassembling the punching die 42. One side of the clamping component 49 is fixedly connected to the blanking base 47, and the other side is a semi-enclosed clamping end 492. The tail of the clamping end 492 is driven by a clamping cylinder 491 to clamp and fix the punching die 42 in the middle. The clamping cylinder 491 is fixedly connected to the blanking base 47. The semi-enclosed shape of the clamping end 492 is a U-shaped or C-shaped structure, and the inner wall of the clamping end 492 is provided with anti-slip texture. When it is necessary to change the punching die 42, the clamping cylinder 491 is activated to release the clamping end 492, the old die is removed, and the new die is placed in. The clamping cylinder 491 is activated again to clamp the new die with the clamping end 492, thus completing the quick die change. The anti-slip texture ensures that the punching die 42 does not shift or vibrate during the blanking process.

[0033] IV. The equipment's cyclical working process The complete working cycle of the device of this invention is as follows: Step 1 – Synchronous Lateral Movement: The front lateral movement cylinder 190, the rear lateral movement cylinder 1 26, and the rear lateral movement cylinder 2 27 operate synchronously. The front lateral movement cylinder 190 pushes the front paper-moving slide 12 to slide laterally along the front paper-moving base 11 via the connecting piece 18, causing the paper feed roller and the paper 3 to move laterally. At the same time, the rear lateral movement cylinder 1 26 drives the left push plate 24, and the rear lateral movement cylinder 2 27 drives the right push plate 25, applying pushing force synchronously from both sides of the paper 3, so that the rear section of the paper 3 maintains the same lateral displacement as the front section. Through the coordinated operation of the front paper-moving mechanism 1 and the rear paper-moving mechanism 2, the entire sheet of paper 3 completes a preset amount of lateral swing at the cutting station.

[0034] Step Two – Paper Forward Movement: After the synchronous traverse is completed, the paper feeding motor 143 starts, driving the lower roller 14 to rotate via the coupling 142. Under the action of the compression spring 152, the upper roller 15, together with the lower roller 14, clamps the paper 3, conveying the paper 3 forward a preset distance. This forward movement distance matches the spacing between adjacent punches in the punch assembly 41, ensuring that after the paper 3 moves forward, the new area to be punched is exactly below the punch assembly 41.

[0035] Step 3 – Positioning and Punching: After the paper 3 moves into position, the punching mechanism 4 operates. First, the positioning guide cylinder 46 drives the positioning base 45 to descend, causing the punching top seat 43 and the punch rod assembly 41 to descend together to the preset punching height, initially positioning the punch rod assembly 41. Then, the upper push motor 48 drives the punching base 47 to rise, causing the punching die 42 to rise to a position contacting the bottom surface of the paper 3, precisely aligning the die hole of the punching die 42 with the upper punch rod assembly 41. Next, the lower punch cylinder 44 drives the punching top seat 43 to move rapidly downward along the guide post 414, causing the punch rod assembly 41 to pass through the punching guide hole 415 on the positioning punching plate 412, cooperating with the punching die 42 to punch out a circular paper piece from the paper 3. After punching is completed, the lower punch cylinder 44 drives the punch rod assembly 41 to retract and rise, the upper push motor 48 drives the punching die 42 to descend back to its original position, and the positioning guide cylinder 46 drives the positioning base 45 to rise back to its original position, completing one punching cycle.

[0036] The process consists of three steps: synchronous lateral movement, paper forward movement, and positioning punching, which are repeated sequentially. Since the lateral swing of the paper 3 in each cycle can be preset (achieved by controlling the strokes of the front lateral movement cylinder 190, the rear lateral movement cylinder 26, and the rear lateral movement cylinder 27), the punching holes from adjacent cycles are misaligned in the lateral direction of the paper 3, resulting in staggered punching holes on the paper 3. Compared to the traditional fixed array arrangement, the staggered arrangement optimizes the spacing between adjacent holes, allowing for more holes to be arranged on the same paper area, effectively improving the material utilization rate of the paper.

[0037] V. Verification of the beneficial effects of the equipment Taking a 1m×1m sheet of paper as an example, when using the traditional fixed array method to cut a circular paper sheet with a diameter of 30mm, the center-to-center distance of the holes needs to be maintained at more than 35mm (the edge distance of the holes is at least 5mm). A single sheet of paper can accommodate approximately 27×27=729 paper sheets. Using the oscillating cutting device of this invention, by controlling the lateral oscillation of the paper in each cycle to 17.5mm (i.e., half the center-to-center distance of the holes), the holes in odd-numbered rows and even-numbered rows are staggered by half a hole distance in the lateral direction. While keeping the center-to-center distance of the holes unchanged at 35mm in the longitudinal direction, the actual minimum distance between adjacent holes in the lateral direction remains 5mm. However, the number of holes that can be arranged in the width direction of the paper increases from 27 columns to approximately 31 columns. A single sheet of paper can accommodate approximately 31×27=837 paper sheets, improving the material utilization rate by approximately 14.8%. Meanwhile, the three-step cycle working mode ensures that the horizontal swing of the paper, the vertical feed and the cutting action are connected in an orderly and coordinated manner, and the actions of each mechanism do not interfere with each other and are precisely positioned. This effectively avoids paper skewing, wrinkling or cutting position deviation caused by disordered actions, and significantly improves production efficiency and product yield.

[0038] VI. Adjustment of Equipment Operating Parameters In actual production, users can flexibly adjust the operating parameters of each mechanism according to the specifications of the paper sheet being cut and the material characteristics of the paper. Specifically, by adjusting the strokes of the front transverse cylinder 190, the rear transverse cylinder 26, and the rear transverse cylinder 27, the lateral swing amount of the paper 3 in each cycle can be changed; by adjusting the number of rotations of the paper feeding motor 143, the forward movement distance of the paper 3 in each cycle can be changed; by adjusting the air pressure and stroke of the lower punch cylinder 44, the lower punch speed and cutting force of the punch rod assembly 41 can be changed to adapt to paper of different thicknesses and materials. All of the above adjustments can be automated through a PLC controller (programmable logic controller), which is easy to operate and precise in adjustment.
