Description

Technical Field

[0001] This utility model relates to the field of firecracker production technology, and more specifically to a firecracker cartridge substrate processing device. Background Technology

[0002] Firecrackers mainly consist of a paper tube, gunpowder, a base to support the gunpowder, and a fuse. The gunpowder inside the firecracker is ignited by lighting the fuse, which causes the firecracker to explode.

[0003] According to publication (announcement) number CN219265129U, published (announcement) date 2023-06-27, a firecracker cartridge substrate processing device is disclosed, including a support platform, a support column fixedly connected to the side of the support platform, a rotating shaft movably sleeved inside the support column, a roller fixedly sleeved outside the rotating shaft, and a first pulley fixedly sleeved outside the rotating shaft, a conveyor belt movably sleeved outside the roller, a placement box fixedly connected to the top of the conveyor belt, a paper tube movably sleeved inside the placement box, a support frame fixedly connected to the top of the support platform, an electric push rod fixedly installed inside the support frame, a lifting plate fixedly connected to the bottom of the electric push rod, a pressing column fixedly connected to the bottom of the lifting plate, an auxiliary mechanism provided on the top of the lifting plate, a transmission mechanism provided on the front of the support platform, and a sealing mechanism provided inside the support frame. This device, equipped with an electric push rod, allows for the simultaneous processing of multiple firecracker cartridge substrates. When processing is required, a paper tube is placed inside the placement box, and the lower part of the lifting plate is moved. The electric push rod, via the lifting plate, drives the pressing columns downwards, causing multiple pressing columns to compress the filling material inside multiple paper tubes. This confines and fixes the filling material inside the paper tubes, achieving the effect of processing multiple firecracker cartridge substrates simultaneously. This avoids the slow process of manual processing of firecracker cartridge substrates, thereby improving the processing efficiency of firecracker cartridge substrates.

[0004] In the prior art, including the aforementioned patent, when manufacturing the firecracker base, the base material is generally injected into a paper tube, and then a pressure bar is used to compact the base material in the paper tube to form a base that supports the gunpowder. However, during the compaction of the base material, the bottom of the paper tube is subjected to greater pressure, and the distribution of the base material in the paper tube is not particularly uniform. This results in an even more unbalanced pressure on the paper tube. During the compaction of the base material, the paper tube is easily deformed due to the unbalanced pressure, affecting the quality of the produced firecrackers. Utility Model Content

[0005] The purpose of this invention is to provide a device for processing firecracker cartridges, which aims to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides a firecracker cartridge substrate processing device, including a frame, on which the following components are movably mounted:

[0007] Compression bar;

[0008] Multiple movable shells, the multiple movable shells combined to form an outer limiting shell;

[0009] Mounting block, on which multiple first movable blocks and multiple second movable blocks are movable, the pressure rod moves to cause the mounting block to embed into the firecracker paper tube, and the multiple first movable blocks and multiple second movable blocks combine to form a clamping ring adapted to the outer limiting shell and used to clamp the firecracker paper tube.

[0010] Preferably, the mounting block is rotatably provided with a drive disk for driving the first movable block and the second movable block.

[0011] Preferably, the drive disk is provided with a guide groove for guiding the movement of the first movable block, the guide groove including an arc portion and a ring portion concentric with the drive disk.

[0012] Preferably, the drive disk is provided with an arc groove for guiding the movement of the second movable block.

[0013] Preferably, a cable is wound around the drive disc, and one end of the cable is fixedly installed on the pressure rod.

[0014] Preferably, a torsion spring is provided between the drive disk and the mounting block.

[0015] In the above technical solution, the firecracker cartridge base processing device provided by this utility model has the following beneficial effects: During the production process, a paper tube filled with base material is placed in an outer limiting shell, which clamps the paper tube. At this time, the pressure rod moves downward, the mounting block moves upward and embeds into the bottom of the paper tube, and then the first movable block and the second movable block extend to the outside of the mounting block to form a clamping ring. The clamping ring cooperates with the outer limiting shell to clamp the bottom of the paper tube. At this time, the pressure rod is also gradually inserted into the paper tube to compact the base material in the paper tube. The bottom of the paper tube is clamped and limited by the clamping ring and the outer limiting shell, so the paper tube is not easily deformed, thus ensuring the quality of the produced firecrackers.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-4 As shown, a firecracker cartridge substrate processing device includes a frame 1, on which the following are movably mounted:

[0025] Compression bar 13;

[0026] Multiple movable shells 121 are combined to form an outer limiting shell 12;

[0027] Mounting block 11, on which multiple first movable blocks 111 and multiple second movable blocks 112 are movable, pressure rod 13 moves to make mounting block 11 embed into firecracker paper tube, and multiple first movable blocks 111 and multiple second movable blocks 112 combine to form a clamping ring adapted to the outer limiting shell 12 and used to clamp the firecracker paper tube.

[0028] Specifically, the pressure rod 13 in the above embodiment can be driven by a motor or manually, and a spring is provided between the movable shell 121 and the frame 1.

[0029] Furthermore, during the production process, the paper tube filled with the base material is placed in the outer limiting shell 12, which clamps the paper tube. At this time, the pressure rod 13 moves downward, and the mounting block 11 moves upward and embeds into the bottom of the paper tube. Then, the first movable block 111 and the second movable block 112 extend to the outside of the mounting block 11 to form a clamping ring. The clamping ring, together with the outer limiting shell 12, clamps the bottom of the paper tube. At this time, the pressure rod 13 is also gradually inserted into the paper tube, compacting the base material in the paper tube. The bottom of the paper tube is clamped and limited by the clamping ring and the outer limiting shell 12, making the paper tube less prone to deformation and ensuring the quality of the produced firecrackers.

[0030] In the above technical solution, during the production process, a paper tube filled with matrix material is placed in the outer limiting shell 12, which clamps the paper tube. At this time, the pressure rod 13 moves downward, and the mounting block 11 moves upward and embeds into the bottom of the paper tube. Then, the first movable block 111 and the second movable block 112 extend to the outside of the mounting block 11 to form a clamping ring. The clamping ring, together with the outer limiting shell 12, clamps the bottom of the paper tube. At this time, the pressure rod 13 is also gradually inserted into the paper tube, compacting the matrix material in the paper tube. The bottom of the paper tube is clamped and limited by the clamping ring and the outer limiting shell 12, making the paper tube less prone to deformation and ensuring the quality of the produced firecrackers.

[0031] As a further embodiment of this utility model, a drive disk 115 for driving the first movable block 111 and the second movable block 112 is rotatably provided on the mounting block 11. The drive disk 115 is provided with a guide groove 116 for guiding the movement of the first movable block 111. The guide groove 116 includes an arc portion 117 and an annular portion 118 concentric with the drive disk 115. The drive disk 115 is provided with an arc groove 119 for guiding the movement of the second movable block 112. The first movable block 111 is provided with a first tenon 113 adapted to the guide groove 116. The second movable block 112... The 12 is provided with a second tenon 114 that matches the arc groove 119; during the production process, the paper tube filled with matrix material is placed between multiple movable shells 121 on the frame 1. At this time, the multiple movable shells 121 are pushed by springs to form an outer limiting shell 12 and clamp the paper tube. At this time, the pressure rod 13 moves downward. The pressure rod 13 drives the mounting block 11 to move upward through the cable 131 and embed it into the bottom of the paper tube. The pressure rod 13 continues to move downward and pulls the drive plate 115 to rotate. The torsion spring between the drive plate 115 and the mounting block 11 accumulates elastic potential energy and drives the rotation of the paper tube. The guide groove 116 on the disc 115 pushes the first tenon block 113 to move. The first tenon block 113 first moves along the arc portion 117, and the first movable block 111 moves outward from the mounting block 11. Then, the first tenon block 113 moves along the ring portion 118, while the first movable block 111 remains stationary. At this time, the second tenon block 114 always moves along the arc groove 119, causing the second movable block 112 to move outward from the mounting block 11 and embed between two adjacent first movable blocks 111 to form a clamping ring. The clamping ring, together with the outer limiting shell 12, clamps the bottom of the paper tube. At this time, the pressure rod 13... The paper tube is gradually inserted into the paper tube, compacting the base material inside. The bottom of the paper tube is clamped and limited by the clamping ring and the outer limiting shell 12, making the paper tube less prone to deformation and ensuring the quality of the produced firecrackers. After the extrusion work is completed, the pressure rod 13 moves upward and the cable 131 is released. At this time, the torsion spring releases its elastic potential energy, driving the drive disc 115 to rotate in the opposite direction, causing the first movable block 111 and the second movable block 112 to retract into the mounting block 11. Then, the mounting block 11 retracts into the frame 1 under the action of the spring, at which point the paper tube can be removed from the outer limiting shell 12.

[0032] As a further embodiment of this utility model, a cable 131 is wound around the drive disc 115, and one end of the cable 131 is fixedly installed on the pressure rod 13. A torsion spring is provided between the drive disc 115 and the mounting block 11, and a spring is provided between the mounting block 11 and the frame 1. The cable 131 has a certain elasticity. During the production process, the paper tube filled with matrix material is placed between multiple movable shells 121 on the frame 1. At this time, the multiple movable shells 121 are pushed by the spring to form an outer limiting shell 12 and clamp the paper tube. At this time, the pressure rod 13 moves downward. The pressure rod 13 drives the mounting block 11 to move upward through the cable 131 and embed into the bottom of the paper tube. The pressure rod 13 continues to move downward and pulls the drive disc 115 to rotate. The torsion spring between the drive disc 115 and the mounting block 11 accumulates elastic potential energy. The guide groove 116 on the drive disc 115 pushes the first tenon block 113 to move. The first tenon block 113 first moves along the arc 117, and the first movable block 111 moves towards... The mounting block 11 moves outward, then the first tenon block 113 moves along the ring 118, the first movable block 111 remains stationary, and the second tenon block 114 moves along the arc groove 119, causing the second movable block 112 to move outward toward the mounting block 11 and embed between two adjacent first movable blocks 111 to form a clamping ring. The clamping ring, in conjunction with the outer limiting shell 12, clamps the bottom of the paper tube. At this time, the pressure rod 13 is also gradually inserted into the paper tube, compacting the base material in the paper tube. The bottom of the paper tube is clamped and limited by the clamping ring and the outer limiting shell 12, making the paper tube less prone to deformation and ensuring the quality of the produced firecrackers. After the extrusion work is completed, the pressure rod 13 moves upward, the cable 131 is released, and the torsion spring releases its elastic potential energy to drive the drive disc 115 to rotate in the opposite direction, causing the first movable block 111 and the second movable block 112 to retract into the mounting block 11. Then, the mounting block 11 retracts into the frame 1 under the action of the spring, at which point the paper tube can be removed from the outer limiting shell 12.
