Description

Technical Field

[0001] The utility model relates to the technical field of firecracker knitting equipment, and more specifically to a feeding device for a firecracker knitting machine. Background Art

[0002] The production of firecrackers generally includes multiple processes such as paper cutting, rolling, charging, fuse cutting, fuse inserting, packaging, and knitting. In the prior art, a firecracker knitting machine is used for knitting and packaging multiple firecrackers.

[0003] According to the publication (announcement) number: CN2735293Y, the publication (announcement) date: October 19, 2005, a feeding device for a firecracker knitting machine is disclosed.

[0004] In the prior art including the above patent, the feeding section of the feeding port arranges the stacked firecrackers in a single row. When the firecrackers advancing downward in a single row reach the knitting position, the fuse at the head of the firecracker cartridge is wound and knitted by the main fuse. Usually, the bottom of the firecracker cartridge is restricted by the baffle on the back of the feeding port, and when the firecracker reaches the feeding section position, the pressing plate moving back and forth pushes the head of the cartridge to ensure that the heads and tails are flush after the firecrackers are arranged in a single row, avoiding the problem of irregular firecrackers during the knitting process. However, when the pressing plate presses the head of the cartridge, it will also cause extrusion damage to the fuse, resulting in accidental damage and breakage of the fuse during the combing process before knitting, causing some firecrackers to be unable to be knitted and increasing the defective rate of the entire section of firecrackers. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a feeding device for a firecracker knitting machine, aiming to solve the problems generated above.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0021] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0022] Such as Figures 1-4As shown in the figure, a feeding device for a firecracker knitting machine includes a feeding port 1 provided with a one-way path 11, and also includes a plurality of drainage plates 3 fixedly installed in the feeding port 1, and a drainage channel 31 facing the one-way path 11 is formed between every two drainage plates 3;

[0023] It also includes a pressing plate 4 with a notch 41, the pressing plate 4 is movably matched with the drainage plate 3, and the notch 41 is communicatively matched with the drainage channel 31.

[0024] Specifically, the feeding port 1 has an open end face for the pressing plate 4 to press the cartridge head of the firecracker at this end face, and the pressing plate 4 is driven by an electric push rod to reciprocate. The feeding port 1, the one-way path 11 and the electric push rod are all prior arts and will not be elaborated here.

[0025] Furthermore, the drainage channel 31 is also between the drainage plate 3 and the inner wall of the feeding port 1, so that the firecrackers can enter the plurality of drainage channels 31 and be conveyed downward. The length of the firecracker is greater than the length of the drainage plate 3, making it easier for the pressing plate 4 to press the cartridge head of the firecracker.

[0026] Even further, the notch 41 on the end face of the pressing plate 4 is rounded so that the fuse can slide into the notch 41, and the rounded position faces the drainage channel 31.

[0027] By putting a large number of firecrackers into the feeding port 1, the firecrackers are divided by the plurality of drainage plates 3 and enter the plurality of drainage channels 31 for one-way arrangement and conveyance. At the same time, when the pressing plate 4 approaches the drainage plate 3, the end face of the pressing plate 4 presses the cartridge head of the firecracker, and the fuse is inserted into the notch 41. When the firecracker is conveyed downward along the drainage channel 31, the fuse slides in the notch 41 until the firecracker reaches the one-way path 11, so that the fuse of the firecracker during downward conveyance will not be squeezed by the end face of the pressing plate 4, thus ensuring the safety of the fuse, increasing the integrity of the firecracker, and improving the knitting efficiency of the firecracker.

[0028] As another embodiment further provided by the present utility model, it also includes a pushing plate 2 arranged at the port of the one-way path 11. A transfer path 32 is formed between the plurality of drainage channels 31 and the one-way path 11, and the transfer path 32 is matched with the pushing plate 2.

[0029] Specifically, the pushing plate 2 and its movement mode are prior arts and will not be elaborated here. The transfer path 32 is out of the pressing position of the pressing plate 4.

[0030] When the firecrackers conveyed by the plurality of drainage channels 31 reach the transfer path 32 and converge, the fuse sliding out of the notch 41 is no longer troubled by the extrusion problem. At this time, the converged firecrackers are pushed into the one-way path 11 by the pushing plate 2 so that the knitting machine can knit and process the firecrackers.

[0031] As yet another embodiment further provided by the present utility model, guide plates 42 are arranged on the pressing plate 4 symmetrically with the notch 41 as the center.

[0032] Specifically, the guide plate 42 is located on the other side of the end face of the pressing plate 4 for pressing work, so that the guide plate 42 does not interfere with the pressing of the firecrackers by the pressing plate 4.

[0033] The lead wire in the notch 41 is supported by the additionally lengthened guide plate 42, so that the lead wire is not interfered by the outside world during the downward movement, and the lead wire can be effectively protected before the firecracker enters the transfer channel 32.

[0034] As another embodiment further provided by the present utility model, a trapezoidal guide cavity 43 communicating with the notch 41 is formed between adjacent guide plates 42.

[0035] Specifically, the cross section of the guide cavity 43 is trapezoidal, and the larger bottom surface of the trapezoid faces the feeding port 1.

[0036] When the firecracker slides in the diversion channel 31, the lead wire slides in the guide cavity 43. When the pressing plate 4 reciprocates, the trapezoidal guide cavity 43 will actively approach the head of the firecracker cartridge. Therefore, the side wall of the guide cavity 43 will straighten the lead wire bent in the horizontal direction and abutted against the side wall, making the lead wires of the firecrackers entering the one-way channel 11 more neatly arranged and reducing the combing difficulty.

[0037] As still another embodiment further provided by the present utility model, a rubber pad is arranged on the end face of the pressing plate 4.

[0038] Specifically, the rubber pad (not shown in the figure, prior art, not elaborated here) is installed on the end face of the pressing plate 4 for pressing work.

[0039] Through the rubber pad arranged on the end face of the pressing plate 4, when the head of the firecracker cartridge is squeezed, it can not only meet the neat arrangement of the firecrackers, but also reduce the damage to the head of the cartridge, and avoid the problem of the paper roll of the firecracker bursting.

[0040] Working principle: A large number of firecrackers are put into the feeding port 1, and the firecrackers are divided by a plurality of diversion plates 3 and enter a plurality of diversion channels 31 for one-way arrangement and transportation. At the same time, when the pressing plate 4 approaches the diversion plate 3, the end face of the pressing plate 4 presses the head of the firecracker cartridge, and the lead wire is inserted into the notch 41. When the firecracker is transported downward along the diversion channel 31, the lead wire slides in the notch 41 until the firecracker reaches the one-way channel 11, so that the lead wire of the firecracker during the downward transportation will not be squeezed by the end face of the pressing plate 4, and the additionally lengthened guide plate 42 supports the lead wire in the notch 41, so that the lead wire is not interfered by the outside world during the downward movement, and the lead wire can be effectively protected before the firecracker enters the transfer channel 32, thereby ensuring the safety of the lead wire.

[0041] Only some exemplary embodiments of the present utility model are described by way of illustration. Without doubt, for those of ordinary skill in the art, various different ways can be used to modify the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
