Description

Technical Field

[0001] This invention relates to the field of inner cylinder paper-filling equipment technology, specifically to an inner cylinder paper-filling device. Background Technology

[0002] In the fireworks manufacturing industry, precisely inserting ring-shaped pieces of paper (commonly known as "paper pads") into the inner tube of fireworks is a crucial process. These paper pads play an important role in isolating, buffering, and fixing the gunpowder inside the fireworks tube. The accuracy and integrity of their insertion directly affect the combustion effect and safety of the fireworks. Traditional manual paper stuffing methods are not only inefficient and labor-intensive, but also struggle to ensure consistency in the depth and orientation of each paper piece, leading to inconsistent quality and high safety risks. Existing automated equipment still faces numerous challenges in addressing these issues: for example, after stamping and cutting, the punch or perforating needle may pull out the stuffed paper pieces due to vacuum suction or friction during retraction, causing process failure; paper is prone to shifting during transport and processing, affecting the accuracy of cutting and stuffing; furthermore, the lack of continuity and automation in the entire process restricts further improvements in production efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide an inner cylinder paper-plugging device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an inner cylinder paper-filling device, comprising a support frame, a lower mold fixed on the support frame, a movable material-carrying platform provided on the support frame, a lifting mechanism installed on the support frame for lifting the material-carrying platform, a side bracket installed on the side of the support frame, a support plate fixed at equal intervals between the side bracket and the support frame for supporting the paper, a traction mechanism installed on the side bracket for traction of the paper for equal-interval movement, a vertical bracket fixed on the support frame, an mounting plate fixed on the vertical bracket, a positioning mechanism installed on the mounting plate for flattening and positioning the paper, and a paper-filling mechanism installed on the mounting plate for perforating, cutting, and filling the inner cylinder of the paper for positioning.

[0005] Preferably, a rotatable paper roll mounting shaft is installed on the other side of the support frame opposite to the side bracket, and a guide wheel with a bearing connected to the support frame is installed on the side of the paper roll mounting shaft. Furthermore, visual inspection mechanisms fixed on the support frame are symmetrically arranged on the side of the guide wheel. Through the above structure, the paper roll can be installed, released, and offset detected, ensuring the correct position of the paper.

[0006] Preferably, the lifting mechanism includes a fixed plate fixed to the support frame, and a first hydraulic cylinder is fixed to the lower end face of the fixed plate. A support platform is fixed to the output end of the first hydraulic cylinder, and a first guide post is fixed to the lower end face of the support platform. The first guide post and the fixed plate are slidably connected. The support platform is located directly below the lower mold. By extending the first hydraulic cylinder, the material loading platform can be separated from the support frame, thereby realizing the lifting effect of the material loading platform and the firework tube on the material loading platform, and thus realizing the positioning effect of the firework tube, which facilitates the normal operation of subsequent paper stuffing.

[0007] Preferably, the traction mechanism includes a second hydraulic cylinder fixed on the side support, and a fixed clamping plate is fixed to the output end of the second hydraulic cylinder. The fixed clamping plate and the crossbar are slidably connected. At the same time, the crossbar is fixed between the side support and the support frame. The upper surface of the fixed clamping plate is flush with the upper surface of the pallet. The fixed clamping plate is driven to move left and right by the second hydraulic cylinder, which can provide a basic guarantee for the automatic traction and feeding of paper, thereby ensuring the normal operation of the device.

[0008] Preferably, a fixed frame is fixed to the fixed clamp, and a limit plate is fixed to the fixed frame. A third hydraulic cylinder is also symmetrically fixed to the fixed frame, and a movable plate is fixed to the output end of the third hydraulic cylinder. A second guide post is symmetrically fixed to the movable plate, and the second guide post is slidably connected to the fixed frame. A positioning shaft is also evenly fixed to the lower end of the movable plate, and the positioning shaft is slidably connected to the limit plate. The positioning shaft is nested to the round hole on the fixed clamp. Through the above structure, the paper end can be clamped and fixed, thereby ensuring the stability of the paper and providing a basic guarantee for the traction and movement of the paper.

[0009] Preferably, the positioning mechanism includes a fourth hydraulic cylinder fixed to the mounting plate, and a top plate is fixed to the output end of the fourth hydraulic cylinder. The top plate is fixed to one end of the connecting rod, and the other end of the connecting rod is fixed to the lower pressure plate. The lower pressure plate is located directly above the lower mold, and first limiting blocks are symmetrically fixed on the lower pressure plate. The fourth hydraulic cylinder can drive the top plate, connecting rod, and lower pressure plate to move downward. By cooperating with the lower mold, the lower pressure plate can achieve the pressing and limiting effect on the paper on the upper surface of the lower mold, thereby ensuring the flatness of the paper.

[0010] Preferably, the paper-feeding mechanism includes a fifth hydraulic cylinder fixed to the mounting plate, and the output end of the fifth hydraulic cylinder is fixed to the round rod. A movable plate is fixed on the round rod, and a second limiting block is fixed on the upper surface of the movable plate. The second limiting block contacts the mounting plate to achieve a positioning function. The fifth hydraulic cylinder drives the round rod and the movable plate to move. With the positioning function of the second limiting block, the highest position of the movable plate can be limited, thereby ensuring the normal operation of the device.

[0011] Preferably, the round rod is further fixed with a mounting bracket disposed below the movable plate, and the mounting bracket, the movable plate and the connecting rod are slidably connected, and the mounting bracket, the movable plate and the guide rod are slidably connected. At the same time, the guide rod is fixed between the mounting plate and the support frame. Through the above structure, the moving guide function of the mounting bracket and the movable plate can be realized, ensuring that the mounting bracket and the movable plate make stable linear movements.

[0012] Preferably, the mounting frame is provided with a movable clamping plate that can move up and down, and a spring is fixed between the movable clamping plate and the mounting frame. A sliding rod is fixed on the movable clamping plate, and the sliding rod is slidably connected to the mounting frame, the movable plate, the lower pressure plate, the top plate, and the mounting plate. A positioning ring is also fixed on the sliding rod, and the distance between the positioning ring and the upper surface of the mounting plate is less than the distance between the first limiting block and the mounting frame. Through the above structure, a basic force can be provided for the movement of the movable clamping plate, and the elasticity of the spring can provide a basic guarantee for the automatic reset of the movable clamping plate.

[0013] Preferably, perforating needles are evenly fixed on the movable clamp, and the perforating needles and punches are slidably connected. The punches are fixed on the base plate, and the base plate and the mounting bracket are fixed by bolts. The perforating needles can be used to perforate the paper, and the punches can be used to cut the paper, so that the paper is inserted into the firework tube in a circular structure.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This inner tube paper-filling device adopts a unique punch retraction design. The positioning ring and the mounting plate achieve hard limiting, which forces the perforating needle to stop and retract relatively before the paper is inserted into place. The punch continues to move down a short distance to compact the paper, thus solving the technical problem that the perforating needle will stick and carry the paper out of the firework tube during the return stroke. This greatly improves the success rate and reliability of the paper-filling operation. 2. This inner tube paper-filling device, through the action of the positioning mechanism, can flatten and position the paper before punching and cutting, thereby ensuring the stable punching and cutting of the paper in the later stage. In conjunction with the paper-filling mechanism, it can realize the automatic punching and cutting of the paper. After cutting, when the paper is inserted into the firework tube, the perforation needle can achieve the center positioning of the paper in the early stage, avoiding the paper from tilting during the insertion process, thereby effectively ensuring the processing quality. 3. This inner tube paper feeding device monitors the paper edge in real time through a vision inspection mechanism to ensure that the feeding does not deviate. With the help of the traction mechanism, the stroke of the second hydraulic cylinder can be limited according to the width of the firework tube, thereby realizing automatic feeding of paper at equal intervals, ensuring continuous processing. The entire operation does not require manual intervention, effectively improving processing efficiency. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-11 This invention provides a technical solution: an inner cylinder paper-filling device, including a support frame 1, a lower mold 2 fixed on the support frame 1, a movable material-carrying platform 3 provided on the support frame 1, a lifting mechanism 4 installed on the support frame 1 for lifting the material-carrying platform 3, a side bracket 8 installed on the side of the support frame 1, a support plate 9 fixed at equal intervals between the side bracket 8 and the support frame 1 for supporting the paper, a traction mechanism 10 installed on the side bracket 8 for traction of the paper for equal interval movement, a vertical bracket 11 fixed on the support frame 1, an mounting plate 12 fixed on the vertical bracket 11, a positioning mechanism 13 installed on the mounting plate 12 for flattening and positioning the paper, and a paper-filling mechanism 14 installed on the mounting plate 12 for perforating, cutting, and filling the inner cylinder of the paper for positioning.

[0019] A rotatable paper roll mounting shaft 5 is installed on the other side of the support frame 1 opposite to the side bracket 8, and a guide wheel 6 with a bearing connected to the support frame 1 is installed on the side of the paper roll mounting shaft 5, and a visual inspection mechanism 7 fixed on the support frame 1 is symmetrically arranged on the side of the guide wheel 6. When using the inner tube paper-filling device, such as Figures 1-3 As shown, firstly, according to the number of firework tubes in a set of fireworks, the corresponding number of perforating needles 1411 and punches 1412 are installed to ensure that paper is evenly stuffed into each firework tube. Then, the paper roll is installed on the paper roll mounting shaft 5, and the end of the paper on the paper roll passes through the gap between the lower pressure plate 1304 and the lower mold 2 and contacts the traction mechanism 10. The traction mechanism 10 can realize the automatic traction of the paper. During the movement of the paper, the guide wheel 6 can be used to guide it. With the help of the vision detection mechanism 7, the edge position of the paper can be detected to avoid the paper from shifting. The lifting mechanism 4 includes a fixed plate 401 fixed on the support frame 1, and a first hydraulic cylinder 402 is fixed on the lower end face of the fixed plate 401. A support platform 403 is fixed on the output end of the first hydraulic cylinder 402. At the same time, a first guide post 404 is fixed on the lower end face of the support platform 403. The first guide post 404 and the fixed plate 401 are slidably connected. The support platform 403 is located directly below the lower mold 2. During processing, such as Figures 1-10As shown, a set of firework tubes is placed on the loading platform 3. The loading platform 3 is moved to the top of the support platform 403 by an external conveying mechanism (the accuracy of the moving position of the loading platform 3 can be ensured by using the existing laser positioning and detection mechanism). After the loading platform 3 moves the firework tubes to the top of the support platform 403, the first hydraulic cylinder 402 extends and moves the support platform 403 upward. With the sliding guidance between the first guide post 404 and the fixed plate 401, the stability of the movement of the support platform 403 can be ensured. When the support platform 403 contacts the loading platform 3, the lifting effect of the loading platform 3 and the firework tubes can be realized until the upper end face of the firework tube contacts the lower end face of the lower mold 2, thereby realizing the clamping and positioning effect of the firework tubes. The positioning mechanism 13 includes a fourth hydraulic cylinder 1301 fixed on the mounting plate 12, and a top plate 1302 is fixed to the output end of the fourth hydraulic cylinder 1301. The top plate 1302 is fixed to one end of the connecting rod 1303, and the other end of the connecting rod 1303 is fixed to the lower pressure plate 1304. The lower pressure plate 1304 is located directly above the lower mold 2, and first limiting blocks 1305 are symmetrically fixed on the lower pressure plate 1304. After the firework tube is positioned, the fourth hydraulic cylinder 1301 extends, causing the top plate 1302, connecting rod 1303 and lower pressure plate 1304 to move downward. With the sliding action between the connecting rod 1303 and the mounting frame 1405 and the moving plate 1403, the stability of the downward movement of the top plate 1302 and the lower pressure plate 1304 can be ensured until the lower pressure plate 1304 cooperates with the lower mold 2 to clamp and flatten the paper, thereby achieving the flattening and positioning of the paper. The paper feeding mechanism 14 includes a fifth hydraulic cylinder 1401 fixed on the mounting plate 12, with the output end of the fifth hydraulic cylinder 1401 fixed to a round rod 1402. A movable plate 1403 is fixed on the round rod 1402, and a second limiting block 1404 is fixed on the upper surface of the movable plate 1403. The second limiting block 1404 contacts the mounting plate 12 to achieve positioning. A mounting frame 1405 is also fixed on the round rod 1402 and disposed below the movable plate 1403. The mounting frame 1405, the movable plate 1403, and the connecting rod 1303 are slidably connected. The mounting frame 1405, the movable plate 1403, and the guide rod 1406 are also slidably connected. The guide rod 1406 is fixed between the mounting plate 12 and the support frame 1. A movable clamping plate that can move up and down is provided inside the mounting frame 1405. 1407, and a spring 1408 is fixed between the movable clamping plate 1407 and the mounting bracket 1405, and a sliding rod 1409 is fixed on the movable clamping plate 1407. At the same time, the sliding rod 1409 is slidably connected to the mounting bracket 1405, the movable plate 1403, the lower pressure plate 1304, the top plate 1302, and the mounting plate 12. A positioning ring 1410 is also fixed on the sliding rod 1409, and the distance between the positioning ring 1410 and the upper end face of the mounting plate 12 is less than the distance between the first limiting block 1305 and the mounting bracket 1405. Perforating needles 1411 are evenly fixed on the movable clamping plate 1407, and the perforating needles 1411 and the punches 1412 are slidably connected. The punches 1412 are fixed on the base plate 1413, and the base plate 1413 and the mounting bracket 1405 are fixed by bolts. After the paper is flattened and positioned, as follows: Figures 1-10 As shown, at this time, the extension of the fifth hydraulic cylinder 1401 can drive the round rod 1402, the movable plate 1403, and the mounting bracket 1405 to move downwards. Combined with the sliding guidance between the mounting bracket 1405, the movable plate 1403, and the guide rod 1406, the stability of the downward movement of the movable plate 1403 and the mounting bracket 1405 can be ensured. When the mounting bracket 1405 moves downwards, it simultaneously drives the movable clamping plate 1407, the sliding rod 1409, the perforating needle 1411, and the base plate 1405. 13 and punch 1412 move downwards. When the perforating needle 1411 moves down to contact the paper, the perforating needle 1411 can achieve the center perforation of the finished paper sheet. At this time, the movable clamping plate 1407, slide rod 1409, perforating needle 1411, base plate 1413 and punch 1412 continue to move downwards. When the punch 1412 contacts the paper, the paper can be cut by the engagement of the punch 1412 with the upper die hole of the lower die 2, so that the paper forms a ring structure. Figure 11 As shown, at this time, the movable clamping plate 1407, sliding rod 1409, perforating needle 1411, base plate 1413 and punch 1412 continue to move down. Through the action of punch 1412 and perforating needle 1411, the cut paper can be passed through the lower mold 2 and enter the firework tube, thereby realizing the paper insertion function. During the paper cutting and insertion process, the slide bar 1409 continues to move downward, thereby driving the positioning ring 1410 to move downward. When the positioning ring 1410 moves downward to contact the mounting plate 12, the slide bar 1409 is positioned. At this time, the fifth oil cylinder 1401 extends and continues to drive the base plate 1413 and the punch 1412 downward. The punch 1412 further inserts the paper into the firework tube. At this time, due to the positioning effect of the positioning ring 1410, during the downward movement of the base plate 1413 and the punch 1412, the slide bar 1409, the movable clamping plate 1407 and the perforating needle 1411 move upward relative to the mounting frame 1405, so that the perforating needle 1411 can automatically separate from the formed paper until the mounting frame 1405 contacts the first limit block 1305 to complete the paper insertion action. In summary, during the paper insertion process, the paper is first perforated by the perforating needle 1411, and then cut by the punch 1412. After cutting, the paper is centered by the perforating needle 1411 to prevent the paper from tilting when inserted into the firework tube. The punch 1412 then feeds the cut paper into the firework tube. When the positioning ring 1410 contacts and positions itself with the mounting plate 12, the perforating needle 1411 automatically retracts and separates from the paper. The punch 1412 then presses the paper down a certain distance, effectively preventing the paper from being carried out of the firework tube due to the perforating needle 1411 sticking to the paper during subsequent device reset, thus ensuring the quality of paper insertion. The traction mechanism 10 includes a second hydraulic cylinder 1001 fixed to the side bracket 8, and a fixed clamping plate 1002 fixed to the output end of the second hydraulic cylinder 1001. The fixed clamping plate 1002 is slidably connected to the crossbar 1003, and the crossbar 1003 is fixed between the side bracket 8 and the support frame 1. The upper end face of the fixed clamping plate 1002 is flush with the upper end face of the support plate 9. A fixing frame 1004 is fixed on the fixed clamping plate 1002, and a limit plate 1005 is fixed on the fixing frame 1004. A third hydraulic cylinder 1006 is symmetrically fixed at the front and back of the 4th frame. At the same time, a movable plate 1007 is fixed at the output end of the third hydraulic cylinder 1006. A second guide post 1008 is symmetrically fixed at the front and back of the movable plate 1007. The second guide post 1008 is slidably connected to the fixed frame 1004. A positioning shaft 1009 is also evenly fixed at the lower end of the movable plate 1007. The positioning shaft 1009 is slidably connected to the limiting plate 1005. The positioning shaft 1009 is nested with the round hole on the fixed clamping plate 1002. After the paper is inserted once, the fourth hydraulic cylinder 1301 and the fifth hydraulic cylinder 1401 retract, resetting the device. Combined with the elastic action of the spring 1408, this resets the movable clamping plate 1407, the slide rod 1409, and the perforating needle 1411, allowing for the next processing step. After the device resets, as... Figures 1-7As shown, at this time, by retracting the third hydraulic cylinder 1006, the movable plate 1007 and the positioning shaft 1009 can be moved upward and reset, thereby releasing the clamping and fixing effect on the paper. By extending the second hydraulic cylinder 1001, the fixed clamping plate 1002, the fixed frame 1004, the third hydraulic cylinder 1006, the movable plate 1007, and the positioning shaft 1009 can be moved towards one side of the support frame 1. With the sliding guide effect between the fixed clamping plate 1002 and the crossbar 1003, the stability of the movement of the fixed clamping plate 1002 can be ensured. When the extension length of the second hydraulic cylinder 1001 is equal to the width of the firework tube, the third hydraulic cylinder 1006 extends... The movable plate 1007 and positioning shaft 1009 move downwards, and the positioning shaft 1009 penetrates the paper and nests with the round hole on the fixed clamping plate 1002 (initially, the positioning shaft 1009 needs to penetrate the paper to lock it; later, because there are paper punches on the paper, the positioning shaft 1009 can directly penetrate the paper punches to lock it). This achieves the paper positioning function. At this time, the second hydraulic cylinder 1001 retracts, driving the fixed clamping plate 1002, the fixed frame 1004, the third hydraulic cylinder 1006, the movable plate 1007, and the positioning shaft 1009 to reset, thereby pulling the paper to release it for the next processing.
