Description

Technical Field

[0001] This utility model relates to the field of mud press technology, specifically a fully automatic inner cylinder mud press. Background Technology

[0002] The fully automatic inner cylinder compactor is an indispensable key piece of equipment in the fireworks production process, specifically designed for the precise filling and efficient compaction of the inner cylinder with clay. Utilizing advanced automation technology, it achieves fully automated operation from quantitative clay supply to uniform compaction, significantly improving production efficiency and ensuring that the density and uniformity of the clay filling in each fireworks tube meet stringent process standards, fully satisfying the high requirements of fireworks manufacturing for safety and stability.

[0003] The existing technical solution still has the following problems when used: In actual production applications, existing fully automatic inner cylinder mud pressing machines generally still rely on manual operation to complete the mud particle filling process. This traditional manual filling method not only requires a lot of manpower, but also, due to the limitations of manual speed and precision, it is often difficult to ensure the continuity and uniformity of filling, resulting in relatively low mud pressing efficiency for fireworks tubes. Therefore, improvements are needed to address the aforementioned issues. Utility Model Content

[0004] The purpose of this utility model is to provide a fully automatic inner cylinder mud press to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fully automatic inner cylinder mud press, comprising: a base at the bottom for support; a rotary processing table installed on the upper surface of the base for processing; four positioning components arranged in a circular array on the upper surface of the rotary processing table for positioning the firework tube; a feeding component installed on the upper surface of the base for feeding the lead wire into the firework tube; an automatic filling component installed on the upper surface of the base for filling the firework tube with mud particles; and a compaction component installed on the upper surface of the base for compacting the mud inside the firework tube. The automatic filling assembly includes a filling section connected to the top of the base, a scraping section installed inside the filling section, and an opening and closing section located in the bottom cavity of the filling section and extending to the bottom.

[0006] Preferably, the packing portion includes a housing connected to the upper surface of the base, and a packing hole opened at the bottom of the housing.

[0007] Preferably, the scraping part includes a drive motor mounted on the top of the housing, a rotating rod connected to the output end of the drive motor, a bearing connected to the end of the rotating rod and fitted into the bottom of the housing, and a scraper connected to the side surface of the rotating rod and abutting against the inner wall of the housing.

[0008] Preferably, the opening and closing part includes a perforated plate embedded in the bottom cavity of the housing, a connecting plate connected to the bottom side of the perforated plate and extending to the bottom of the housing, a first telescopic rod connected to the side surface of the connecting plate and installed at the bottom of the housing, a guide groove opened on the bottom side surface of the housing, and a guide column penetrating the guide groove and connected to the bottom side of the perforated plate. The circular holes on the surface of the perforated plate correspond one-to-one with the filling holes and have the same size. When the first telescopic rod extends to the farthest end by pressing the perforated plate through the connecting plate, the circular holes on its surface are completely misaligned with the filling holes.

[0009] Preferably, a ejector assembly for ejecting the processed fireworks tube is provided between the base and the positioning assembly. The ejector assembly includes an ejector part installed on the side surface of the base and a spring-loaded part connected inside the positioning assembly. The positioning assembly includes a base plate connected to the upper surface of a rotary machining table, a support plate connected to the upper surface of the base plate via a spring-loaded part, and a positioning post connected to the upper surface of the support plate.

[0010] Preferably, the ejector portion includes a second telescopic rod installed on the bottom side of the base table and extending to the top, a horizontal plate connected to the movable end of the second telescopic rod, an ejector rod connected to the upper surface of the horizontal plate, four sets of first ejector holes arranged in a ring array on the surface of the rotary processing table, and four sets of second ejector holes corresponding one-to-one with the first ejector holes on the surface of the base plate. When the second telescopic rod drives the ejector rod to move to the highest end of its stroke through the horizontal plate, it passes through the first ejector hole and the second ejector hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. When this fully automatic inner cylinder mud press is in use, the drive motor drives the scraper to rotate through the rotating rod, thereby scraping the mud particles. The mud falls into the firework tube through the filling hole and the round hole of the orifice plate. After the firework tube is filled with mud particles, the first telescopic rod is activated. When the first telescopic rod is in operation, it drives the orifice plate to move axially through the connecting plate. When the axial movement of the orifice plate is completely misaligned with the filling hole, the filling hole can be closed, thereby realizing the automatic mud filling of the firework tube and improving the mud pressing efficiency of the firework tube. 2. When the fully automatic inner cylinder mud press is in use, the second telescopic rod drives the ejector rod to move longitudinally through the horizontal plate. When the ejector rod moves longitudinally, it can squeeze the support plate to move upward and pull the spring strip to deform. When the support plate moves upward, it can squeeze the firework tube. When the firework tube is subjected to force, it can move upward and separate from the surface of the positioning column, thereby realizing the ejection of the firework tube and avoiding the difficulty of removing it from the surface of the positioning column after the mud inside the firework tube is compacted.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-9 This utility model provides a technical solution: a fully automatic inner cylinder mud press, comprising: a base 1 at the bottom for support, a rotary processing table 2 installed on the upper surface of the base 1 for processing, four sets of positioning components 3 connected to the upper surface of the rotary processing table 2 in a circular array for positioning the firework tube, a feeding component 4 installed on the upper surface of the base 1 for feeding the lead wire into the firework tube, an automatic filling component 5 installed on the upper surface of the base 1 for filling the firework tube with mud particles, and a compaction component 6 installed on the upper surface of the base 1 for compacting the mud inside the firework tube. The automatic filling assembly 5 includes a filling part 51 connected to the top of the base 1, a scraping part 52 installed inside the filling part 51, and an opening and closing part 53 located in the bottom cavity of the filling part 51 and extending to the bottom.

[0017] In this fully automatic inner cylinder mud-pressing machine, the fireworks tube is first positioned on the surface of the positioning post 33. Then, the rotating processing table 2 rotates the fireworks tube 90°, at which point the feeding component 4 feeds the lead wire into the fireworks tube. Next, the rotating processing table 2 rotates the fireworks tube another 90° to fill it with mud. As the rotating processing table 2 rotates the fireworks tube another 90°, the compaction component 6 compacts the mud inside the fireworks tube. Finally, the rotating processing table 2 rotates the fireworks tube 360° to remove it and install a new fireworks tube. All of the above are existing technologies. For the specific principles of the fully automatic mud-pressing machine, please refer to patent publication number: CN201266046Y.

[0018] Furthermore, the filling part 51 includes a housing 511 connected to the upper surface of the base 1, and a filling hole 512 opened at the bottom of the housing 511. Soil particles inside the housing 511 can fall through the filling hole 512 and thus fall into the interior of the firework tube at its bottom, thereby achieving soil filling.

[0019] Furthermore, the ash scraping unit 52 includes a drive motor 521 mounted on the top of the housing 511, a rotating rod 522 connected to the output end of the drive motor 521, a bearing 523 connected to the end of the rotating rod 522 and fitted into the bottom of the housing 511, and a scraper 524 connected to the side surface of the rotating rod 522 and abutting against the inner wall of the housing 511. When the drive motor 521 is running, it can drive the rotating rod 522 to rotate inside the bearing 523. When the rotating rod 522 rotates, it can drive the scraper 524 to rotate. When the scraper 524 rotates, it can scrape the soil particles inside the housing 511, thereby filling the firework tube with soil particles.

[0020] Furthermore, the opening and closing part 53 includes a perforated plate 531 embedded in the bottom cavity of the housing 511, a connecting plate 532 connected to the bottom side of the perforated plate 531 and extending to the bottom of the housing 511, a first telescopic rod 533 connected to the side surface of the connecting plate 532 and installed at the bottom of the housing 511, a guide groove 534 formed on the bottom side surface of the housing 511, and a guide post 535 passing through the guide groove 534 and connected to the bottom side of the perforated plate 531; when the perforated plate 531 is subjected to force, it can drive the guide post 535 to slide inside the guide groove 534, which can limit the movement direction of the perforated plate 531 and maintain the stability of the movement.

[0021] The circular holes on the surface of the orifice plate 531 correspond one-to-one with the filling holes 512 and are of the same size. When the first telescopic rod 533 extends to the farthest point by pressing the orifice plate 531 through the connecting plate 532, the circular holes on its surface are completely misaligned with the filling holes 512. After the circular holes of the orifice plate 531 are completely misaligned with the filling holes 512, the filling holes 512 can be sealed by the orifice plate 531, thereby preventing soil particles from falling out of the filling holes 512.

[0022] Furthermore, a top material assembly 7 for ejecting the processed firework tube is provided between the base 1 and the positioning assembly 3. The top material assembly 7 includes an ejection part 71 installed on the side surface of the base 1 and a spring-loaded part 72 connected inside the positioning assembly 3. The positioning assembly 3 includes a base plate 31 connected to the upper surface of the rotary processing table 2, a support plate 32 connected to the upper surface of the base plate 31 via a spring-loaded part 72, and a positioning post 33 connected to the upper surface of the support plate 32.

[0023] Furthermore, the ejector 71 includes a second telescopic rod 711 mounted on the bottom side of the base 1 and extending to the top, a horizontal plate 712 connected to the movable end of the second telescopic rod 711, an ejector rod 713 connected to the upper surface of the horizontal plate 712, four sets of first ejector holes 714 arranged in a ring array on the surface of the rotary processing table 2, and four sets of second ejector holes 715 corresponding to the first ejector holes 714 on the surface of the base plate 31. When the second telescopic rod 711 drives the ejector rod 713 to move to the highest point of its stroke via the horizontal plate 712, it passes through the first ejector holes 714 and the second ejector holes 715. When the second telescopic rod 711 is running, it can drive the horizontal plate 712 to move longitudinally. When the horizontal plate 712 moves longitudinally, it can drive the ejector rod 713 to move longitudinally. When the ejector rod 713 moves longitudinally to the bottom surface of the support plate 32, the ejector rod 713 continues to move upward, which can compress the support plate 32 to move upward.

[0024] Furthermore, the rebound section 72 includes a guide rod 721 that passes through the support plate 32 and is connected to the upper surface of the base plate 31, a first limiting plate 722 connected to the top of the guide rod 721, a second limiting plate 723 connected to the middle of the guide rod 721, and a spring strip 724 connecting the base plate 31 and the support plate 32. When the support plate 32 is subjected to an upward force, it can pull the spring strip 724 to deform. When the force on the support plate 32 disappears, the spring strip 724 can drive the support plate 32 to return to its original position through its own elasticity.

[0025] Working principle: When filling yellow mud using the fully automatic inner cylinder mud press, the drive motor 521 drives the scraper 524 to rotate via the rotating rod 522. When the scraper 524 rotates, it scrapes the mud particles inside the housing 511. The mud can fall into the firework tube through the filling hole 512 and the round hole of the orifice plate 531. When the firework tube is filled with mud particles, the first telescopic rod 533 is activated. When the first telescopic rod 533 is activated, it can squeeze the connecting plate 532 to move axially. When the connecting plate 532 moves axially, it can drive the orifice plate 531 to move axially. When the orifice plate 531 moves axially to the farthest end of its stroke and is completely misaligned with the filling hole 512, it can close the filling hole 512. When another set of firework tubes needs to be filled, the first telescopic rod 533 can be controlled to retract. After the first telescopic rod 533 retracts, the mud filling of the other set of firework tubes can be realized. When the fireworks are processed and rotated to the loading position, the second telescopic rod 711 can be activated. When the second telescopic rod 711 is running, it drives the ejector rod 713 to move longitudinally through the horizontal plate 712. When the ejector rod 713 moves longitudinally to the bottom surface of the support plate 32, the ejector rod 713 continues to move upward, which can squeeze the support plate 32 to move upward and pull the spring strip 724 to deform. When the support plate 32 moves upward, it can squeeze the fireworks tube. When the fireworks tube is subjected to force, it can move upward and detach from the surface of the positioning post 33, thereby realizing the ejection of the fireworks tube. After the fireworks tube is removed, the second telescopic rod 711 is controlled to retract and the ejector rod 713 is reset through the horizontal plate 712. At this time, the support plate 32 is reset by the elasticity of the spring strip 724 itself. This cycle can be repeated to continuously discharge fireworks tubes.

[0026] This is the characteristic of the inner cylinder mud press. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
