[0010] Preferably, the device also includes a pressing edge on the wrapping paper, and the limiting plate is symmetrically provided with upright plates, and multiple pressing rollers are rotatably provided on one side of the outer wall of the upright plates.

[0011] Preferably, an inclined plate is fixedly installed at one end of the baffle relative to the second support frame.

[0012] Preferably, the limiting plate and the regulating plate are both made of stainless steel.

[0013] In the above technical solution, the firecracker flipper provided by this utility model has the following beneficial effects: by using a limiting plate and a straightening plate to limit the top of the firecracker, the problem of firecrackers flipping and popping is avoided. The baffles on the two straightening plates guide and limit the sides of the firecracker, thereby making the firecrackers gather and straighten.

[0021] 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.

[0022] like Figure 1-4 As shown, a firecracker-tying flipper includes a first support frame 1 and a second support frame 2 with a certain distance between them. A support plate 41 is fixedly installed on the first support frame 1, and a limiting plate 4 located above the firecracker is fixedly installed on the support plate 41. A sizing plate 5 is symmetrically slidably arranged on the limiting plate 4, and a baffle 51 located on the side of the firecracker is provided on the sizing plate 5. A wrapping paper 3 is movably arranged on the second support frame 2, and the limiting plate 4 extends above the second support frame 2. By using the limiting plate 4 and the sizing plate 5 to limit the top of the firecracker, the problem of the firecracker flipping or popping is avoided. The baffles 51 on the two sizing plates 5 guide and limit the sides of the firecracker, thus making the firecracker neatly gathered. Then, the wrapping paper 3 on the second support frame 2 is used to cover the tied firecracker, and the limiting plate 4 extending above the second support frame 2 continuously blocks and limits the firecracker, preventing the neatly sized firecracker from flipping or popping again.

[0023] As a further technical solution provided by this utility model, a base plate 53 located between the first support frame 1 and the second support frame 2 is fixedly installed on the baffle 51, and the base plate 53 is located below the firecracker. A transmission belt 6 is movably arranged on the first support frame 1.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the firecrackers on the first support frame 1 are driven by the transmission belt 6 to move to the second support frame 2. The base plate 53 between the first support frame 1 and the second support frame 2 provides support for the firecrackers, preventing them from deforming or overturning. The firecrackers are then transported along the base plate 53 to the wrapping paper 3 for protection.

[0025] Furthermore, the bottom of the limiting plate 4 is provided with curved baffle 45.

[0026] Specifically, such as Figure 3As shown, the curved baffle 45 is located in the middle of the double-sided firecrackers. By moving the double-sided firecrackers on the transmission belt 6, and then using two baffles 51, the firecrackers are brought together towards the center and close to the curved baffle 45. The curved baffle 45, being located in the middle of the double-sided firecrackers, prevents the firecracker fuses from being squeezed and damaged due to the firecrackers being too close together. At the same time, the baffles 51 and the curved baffle 45 further regulate the double-sided firecrackers. The curved surface on the curved baffle 45 can prevent scratches on the outer skin of the firecrackers.

[0027] Furthermore, a fixing block 42 is fixedly installed between the limiting plate 4 and the support plate 41. An adjusting block 71 is slidably arranged on the fixing block 42 along the vertical direction. The screw 7 rotatably arranged on the fixing block 42 and the adjusting block 71 rotate threadedly. A connecting rod 72 is symmetrically hinged on the adjusting block 71, and the first end of the connecting rod 72 is hinged to the regularizing plate 5.

[0028] Specifically, by rotating the screw 7 onto the fixed block 42, the adjusting block 71 and the screw 7 rotate threadedly. At this time, the adjusting block 71, in conjunction with the connecting rod 72, simultaneously drives the two leveling plates 5 to slide on the limiting plate 4 to perform the operation of gathering and separating. Therefore, by adjusting the distance between the two baffles 51, different sizes of firecrackers can be adapted and the degree of gathering and leveling of the firecrackers can be adjusted.

[0029] Furthermore, it also includes the pressing edge 31 on the wrapping paper 3, and the vertical plate 43 is symmetrically arranged on the limiting plate 4, and multiple pressing rollers 44 are rotatably arranged on one side of the outer wall of the vertical plate 43.

[0030] Specifically, such as Figure 4 As shown, the pressing edge 31 on the wrapping paper 3 is folded over the upper sides of the double-sided firecracker to perform a single-sided film coating operation. At this time, the limiting plate 4 is used to limit the firecracker being coated to avoid severe deformation of the firecracker before coating. At the same time, multiple covering pressure rollers 44 on the upright plate 43 are used to press on the pressing edge 31 to apply a certain amount of pressure to the pressing edge 31, so as to avoid problems such as deformation, displacement or overturning of the firecracker when the pressing edge 31 comes into contact with the firecracker.

[0031] Furthermore, an inclined plate 52 is fixedly installed on one end of the baffle 51 relative to the second support frame 2.

[0032] Specifically, the inclined plates 52 on the two baffles 51 are used to limit and guide the firecrackers as they enter between the two baffles 51.

[0033] Furthermore, the limiting plate 4 and the regulating plate 5 are both made of stainless steel.

[0034] Working principle: By using the limiting plate 4 and the aligning plate 5 to limit the top of the firecracker, the problem of firecrackers flipping or popping is avoided. The baffles 51 on the two aligning plates 5 guide and limit the sides of the firecracker, thus making the firecrackers gather and align. Then, the wrapping paper 3 on the second support frame 2 is used to cover the firecrackers. The limiting plate 4 extends above the second support frame 2 to continuously block and limit the firecrackers, preventing the firecrackers from flipping or popping again after being aligned. By folding the pressing edge 31 on the wrapping paper 3 above the firecrackers on both sides, the firecrackers are covered on one side. At this time, the limiting plate 4 limits the firecrackers that are being covered, preventing the firecrackers from deforming too much before covering. At the same time, the multiple covering pressure rollers 44 on the upright plate 43 press against the pressing edge 31, thereby covering the pressing edge 31 to a certain extent, preventing the pressing edge 31 from causing the firecrackers to deform, shift or flip when in contact with the firecrackers.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
