Description

Technical Field

[0001] This utility model relates to the field of fireworks compaction technology, specifically to an inner tube paper compaction device. Background Technology

[0002] Firework inner tube processing is the core process of fireworks production. It refers to the process of making small cylindrical functional units, or "inner tubes," into fireworks by taking raw materials (paper, pyrotechnic agents, fuses, etc.) and processing them through a series of mechanical and manual operations. The inner tube is the "effect core" of the fireworks and usually contains dozens to hundreds of inner tubes. Each inner tube corresponds to a specific firing effect. The firing sequence is controlled by a time-delay fuse to ultimately form a continuous fireworks display.

[0003] Currently, during the processing of fireworks inner tubes, it is necessary to insert the cut paper pieces into the inner tubes. However, during the simultaneous feeding process, due to the large number of inner tubes, some paper pieces will still be some distance from the bottom of the inner tubes, making it difficult to automatically compact all the paper pieces, which affects the overall quality of the fireworks. Utility Model Content

[0004] The purpose of this invention is to provide an inner tube paper compaction device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an inner tube paper compaction device, comprising a frame and a compaction assembly. A conveyor frame is installed on the upper inner side of the frame, and a tooling plate is installed on the top of the conveyor frame. A partition is fixed in the middle of the frame, and a limit assembly is installed at one end of the partition. A positioning assembly is installed in the middle of the partition. The compaction assembly is located on the top of the frame and includes a column, a top plate, a third cylinder, a lifting plate, a drive seat, a slide rod, a compression spring, and a pressure rod. A top plate is installed on the top of the column, and a third cylinder is symmetrically fixed on the top of the top plate. The output end of the third cylinder is connected to the lifting plate, and a drive seat is installed at the bottom of the lifting plate. A slide rod is slidably connected inside the drive seat, and a compression spring is sleeved on the lower outer side of the slide rod, with the bottom of the compression spring abutting against the pressure rod.

[0006] Furthermore, the limiting assembly includes a first cylinder and a limiting seat, with the first cylinder disposed at the middle of one end of the partition, and the output end of the first cylinder connected to the limiting seat.

[0007] Furthermore, the positioning component includes a second cylinder, a support plate, and ejector pins. The output end of the second cylinder is connected to the support plate, and ejector pins are symmetrically arranged on the top of the support plate.

[0008] Furthermore, the top of the ejector pin is tapered, and the ejector pin matches the holes at both ends of the tooling plate.

[0009] Furthermore, the positioning assembly also includes guide rods and a fixing plate, with guide rods fixed at the four corners of the bottom of the tray and a fixing plate installed on the top of the frame.

[0010] Furthermore, the guide rod is slidably connected to the partition, and the partition is fixedly connected to the second cylinder.

[0011] Furthermore, the pressure rod is fixedly connected to the slide rod, and the pressure rod is slidably connected to the fixed plate.

[0012] Furthermore, the fixing plate is fixedly connected to the column, and the column is slidably connected to the lifting plate.

[0013] This utility model provides an inner tube paper compaction device, which has the following beneficial effects: 1. By setting up a compaction component, when the paper pieces in the inner cylinder of the compaction tooling plate are compacted, the third cylinder will drive the lifting plate to slide downward along the outside of the column, so that the drive seat can drive the pressure rod to insert into the inner cylinder through the compression spring and apply pressure to the paper pieces. At this time, the compression spring can provide a certain pressure while also buffering between the pressure rod and the drive seat. Therefore, when some of the paper pieces in the inner cylinder of the fireworks are compacted, the corresponding compression spring will contract, so that the uncompacted pressure rod can continue to press down, thereby ensuring that the paper pieces in each inner cylinder of the fireworks are compacted, thereby improving product quality. 2. By setting up limiting components and positioning components, this utility model allows the tooling plate to move on the conveyor frame. The limiting seat can block one side of the tooling plate, so that the tooling plate is located at the top of the positioning component. At this time, the second cylinder drives the pallet to move upward, so that the pin can be inserted into the corresponding hole of the pallet, automatically correcting the deviation and positioning it, and pressing it on the fixed plate. This enables the inner tube of the fireworks on the tooling plate to be quickly aligned with the pressure rod without the need for manual adjustment, which helps to improve the automation level of the equipment.

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0017] like Figures 1 to 2 As shown, the inner tube paper compaction device includes a frame 1 and a compaction assembly 7. A conveyor frame 2 is installed on the upper inner side of the frame 1, and a tooling plate 3 is installed on the top of the conveyor frame 2. Conveying rollers are installed on the top of the conveyor frame 2, which contact the bottom sides of the tooling plate 3. These rollers are not shown in the attached drawings. Since this type of conveying structure is a common technical means in this field, and this application does not aim to improve this aspect, its specific structure will not be described in detail. The tooling plate 3 can support and position the inner tube of the fireworks. A partition 4 is fixed in the middle of the frame 1, and a limit assembly 5 is provided at one end of the partition 4. The limit assembly 5 includes a first cylinder 501 and a limit seat 502. The first cylinder 501 is installed in the middle of one end of the partition 4, and the output end of the first cylinder 501 is connected to the limit seat 502. The limit seat 502 can be used to block one side of the tooling plate 3, quickly compacting the tooling plate 3. Initial positioning: A positioning component 6 is installed in the middle of the partition 4. The positioning component 6 includes a second cylinder 601, a support plate 602, and an ejector pin 603. The output end of the second cylinder 601 is connected to the support plate 602, and ejector pins 603 are symmetrically arranged on the top of the support plate 602. The top of the ejector pin 603 is conical, and the ejector pin 603 matches the holes at both ends of the tooling plate 3. When the second cylinder 601 drives the support plate 602 to move upward, the ejector pin 603 can be inserted into the corresponding hole of the support plate 602 for automatic correction and positioning. The positioning component 6 also includes a guide rod 604 and a fixing plate 605. The guide rod 604 is fixed at the four corners of the bottom of the support plate 602, and the fixing plate 605 is installed on the top of the frame 1. The guide rod 604 is slidably connected to the partition 4, and the partition 4 is fixedly connected to the second cylinder 601. The guide rod 604 is used to improve the stability of the support plate 602 when it moves.

[0018] like Figure 2 and Figure 3As shown, the compaction assembly 7 is located on the top of the frame 1, and includes a column 701, a top plate 702, a third cylinder 703, a lifting plate 704, a drive seat 705, a slide rod 706, a compression spring 707, and a pressure rod 708. The top plate 702 is mounted on the top of the column 701, and the third cylinder 703 is symmetrically fixed on the top of the top plate 702. The output end of the third cylinder 703 is connected to the lifting plate 704, and the drive seat 705 is mounted on the bottom of the lifting plate 704. The fixing plate 605 is fixedly connected to the column 701, and the column 701 is slidably connected to the lifting plate 704. The column 701 can limit and guide the lifting plate 704, improving its movement. To ensure stability, a slide rod 706 is slidably connected inside the drive base 705, and a compression spring 707 is sleeved on the lower outer side of the slide rod 706. The bottom of the compression spring 707 abuts against a pressure rod 708. The compression spring 707 buffers the pressure rod 708 and the drive base 705, ensuring that the paper in each firework inner tube can be compacted. The pressure rod 708 is fixedly connected to the slide rod 706 and slidably connected to the fixed plate 605. The third cylinder 703 drives the lifting plate 704 to slide downward along the outer side of the column 701, so that the drive base 705 can drive the pressure rod 708 to be inserted into the inner tube through the compression spring 707 to apply pressure to the paper.

[0019] In summary, when using this inner tube paper compaction device, firstly according to... Figure 1 , Figure 2 and Figure 3 In the structure shown, after the inner cylinder on the tooling plate 3 is filled with paper in the previous processing equipment, it can be moved to the limiting component 5 via the conveyor frame 2. Then, when the tooling plate 3 moves on the conveyor frame 2, the first cylinder 501 drives the limiting seat 502 to block one side of the tooling plate 3, so that the tooling plate 3 is located on top of the positioning component 6. At this time, the second cylinder 601 drives the support plate 602 to move upward, so that the ejector pin 603 can be inserted into the corresponding hole of the support plate 602, automatically correcting and positioning it, and pressing it on the fixing plate 605. This allows the inner cylinder of the firework on the tooling plate 3 to quickly align with the pressure rod 708. Then, the third cylinder 703 drives the lifting plate 704 to move along the outside of the column 701 towards... Sliding downwards allows the drive seat 705 to drive the pressure rod 708 into the inner cylinder via the compression spring 707, applying pressure to the paper. At this time, the compression spring 707 provides a certain pressure while also buffering the pressure rod 708 and the drive seat 705. Therefore, when some of the paper in the inner cylinder of the fireworks is compacted, the corresponding compression spring 707 will contract, allowing the uncompacted pressure rod 708 to continue pressing down, thus ensuring that the paper in each inner cylinder of the fireworks is compacted. Finally, after compaction, the third cylinder 703, the second cylinder 601, and the first cylinder 501 are reset in sequence, allowing the tooling plate 3 to descend back onto the conveyor frame 2 for easy transfer to the next workstation.
