Description

Technical Field

[0001] This utility model relates to a pressure tongue block for a hole-punching and insertion device for fireworks arrays. Background Technology

[0002] In the prior art, Chinese invention patent document CN 105486179 A discloses a "firework tube punching and insertion device". In the punching and insertion device of the disclosed firework tube machine, the lead wire conveying mechanism 17 conveys the lead wire 19 between the tongue and the lower stop 14. The lead wire cutting blade 10 cuts the lead wire 19, and the middle part of the cut lead wire segment is clamped between the downward pressing tongue block 15 and the forward-extending stop 14. Then, the lead wire guide grooves 13 placed on both sides move downward, bending the two ends of the lead wire segment into an inverted U-shape on the stop 14. At the same time, the two sides of the lead wire segment enter the lead wire guide groove 13. When the lead wire guide groove 13 descends and approaches the paper tube, the stop 14 retracts, and the pressing tongue block 15 pushes the lead wire 19 into the lead wire hole of the paper tube under the pressure of the compression spring 16, completing the insertion work.

[0003] like Figure 1 As shown, the above-mentioned pressing tongue block 15 includes a drive rod 15-1 and a tongue body 15-2. The drive rod 15-1 is connected to a drive component to drive the pressing tongue block 15 to move up and down in a linear reciprocating motion. The tongue body 15-2 cooperates with the stop 14 to clamp the lead wire 19. The mating part between the tongue body 15-2 and the stop 14 may be provided with an arc-shaped notch 15-3.

[0004] The drawback of the existing technology is that the tongue of the ignition block and the stop collide hard to clamp the fuse, which may ignite the fuse and cause safety problems. At the same time, the hard collision pulverizes the granular gunpowder inside the fuse, causing changes in the burning rate of the fuse and failing to achieve the purpose of precisely adjusting the ignition time. Utility Model Content

[0005] To address the aforementioned drawbacks, the technical problem this utility model aims to solve is to provide a flexible pressing tongue block for a firework assembly punching and inserting device, effectively improving safety and preventing changes in the burning rate of the fuse. The technical solution adopted by this utility model is a flexible pressing tongue block for a firework assembly punching and inserting device. The pressing tongue block includes a drive rod and a tongue body. The pressing tongue block cooperates with a lower stop to clamp the fuse segment. The tongue body has a notch at its lower part, within which a flexible body is fitted. The notch and the sides of the flexible body are provided with clips fixed to the tongue body.

[0006] The beneficial effects of this utility model are that the flexible body is made of a flexible material (such as rubber, plastic, or similar material), and is fixedly installed at the lower end of the tongue by a snap-fit ​​method and the support of the clip, thereby effectively buffering the hard collision between the tongue and the stop. This effectively improves safety and avoids changes in the burning rate of the lead wire; the flexible body is firmly installed and will not fall off due to collision.

[0007] Preferably, the clip has a through hole, which is positioned corresponding to the location of the flexible body. This facilitates the disassembly and replacement of the flexible body.

[0008] Preferably, the lower end of the clip has an arc-shaped notch. This facilitates bending both ends of the lead segment into an inverted U-shape.

[0009] Preferably, the flexible body has a larger end and a smaller end, and hooks are provided on both sides of the connecting portion between the larger end and the smaller end; the shape of the notch corresponds to the flexible body, and a hanging portion is provided corresponding to the position of the hooks. The flexible body is securely installed by the hooks and hanging portions engaging with each other, preventing it from falling off.

[0010] Preferably, the flexible body has two larger ends, and the connecting portion between the two larger ends is a smaller inner neck; the shape of the notch is corresponding to the flexible body, and the connecting portion between the two larger ends of the notch is a smaller outer neck, with the inner neck snapped into the outer neck. The snapping of the inner and outer necks achieves a secure installation of the flexible body, preventing it from falling off. Furthermore, the two larger ends of the flexible body are symmetrically shaped, such as two symmetrically distributed trapezoids. When one larger end wears out in the working position, the other larger end can be replaced, extending its service life.

[0011] Preferably, the flexible body has holes to better achieve a cushioning effect.

[0012] Preferably, the notch and both sides of the flexible body are provided with clips fixed to the tongue. The two clips clamp and fix the flexible body.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time.

[0020] Figure 6 This is a schematic diagram of the structure of the flexible body in Example 3. Detailed Implementation

[0021] Example 1: See Appendix Figure 2-4 This describes a specific structure of the present invention. The flexible pressing tongue block of the fireworks assembly punching and inserting device includes a drive rod 101 and a tongue body 102. The pressing tongue block cooperates with the retractable stop 111 below to clamp the lead wire segment 112, and also includes a flexible body 104. The lower end of the tongue body 102 is provided with a notch 103, and the flexible body 104 is fitted into the notch 103. The two sides of the notch 103 and the flexible body 104 are respectively provided with a front clamping piece 105 and a rear clamping piece 108 fixed to the tongue body 102.

[0022] In the example, the flexible body 104 has a larger end and a smaller end, and hooks 109 are provided on both sides of the connecting portion between the larger and smaller ends; the shape of the notch 103 corresponds to the flexible body 104, and a hanging portion 110 is provided corresponding to the position of the hooks 109. Utilizing the deformable property of the flexible body, it is inserted between the front clamp 105 and the rear clamp 108 and secured within the notch 103. Under the clamping of the two clamps, the hooks 109 and the hanging portion 110 securely install the flexible body 104, preventing it from falling off. The lower end of the flexible body 104 cooperates with the stop 111 to clamp the lead segment 112, thereby effectively buffering the hard collision between the tongue 102 and the stop 111. This prevents the ignition of the lead segment 112 to improve safety; prevents the granular gunpowder wrapped inside the lead segment 112 from being pulverized, and prevents changes in the burning rate of the lead; the flexible body 104 is securely installed and will not fall off due to collision.

[0023] In the example, the front clip 105 and the rear clip 108 are provided with through holes 106, which are positioned corresponding to the flexible body 104. This allows for easy disassembly by using a screwdriver or other tools to push the flexible body 104 outward from the through holes 106, facilitating replacement of the flexible body.

[0024] In the example, the lower ends of the front clip 105 and the rear clip 108 have arc-shaped notches 107 that mate with the stop 111. This facilitates the pre-bending of both ends of the lead segment 112, making it easier for the lead guide groove (not shown in the figure) to bend it into an inverted U-shape.

[0025] Example 2: See Appendix Figure 5 This example illustrates another specific structure of the present invention. The difference lies in that, in this example, the flexible body has a larger circular end 201 and a larger strip-shaped end 202, with a smaller inner neck 203 connecting the two larger ends; the shape of the notch corresponds to the flexible body, and the connecting portion between the two larger ends of the notch is a smaller outer neck, with the inner neck 203 snapped into the outer neck. The snapping of the inner and outer necks ensures a secure installation of the flexible body, preventing it from falling off.

[0026] In the example, the flexible body has holes 204, and the deformation of the holes 204 during a collision can better achieve a buffering effect.

[0027] Example 3: See Appendix Figure 6 This example illustrates another specific structure of the present invention. The difference from Embodiment 2 is that, in this example, the flexible body has two symmetrically distributed lower trapezoidal bodies 301 and upper trapezoidal bodies 302 at its two larger ends. The connection between the lower trapezoidal bodies 301 and upper trapezoidal bodies 302 is a smaller inner neck 303; when the lower trapezoidal body 301 in the working position wears out, the upper trapezoidal body 302 can be replaced to the working position. This extends the service life of the flexible body.

[0028] In the example, both the lower trapezoidal body 301 and the upper trapezoidal body 302 of the flexible body are provided with holes 304, so that they can better achieve the buffering effect.
