Description

Technical Field

[0001] The utility model relates to the field of fireworks and firecrackers processing, in particular to a feeding device for a firecracker tying machine. Background Art

[0002] The firecracker tying process is an important part of the firecrackers processing technology. At present, the existing firecracker tying machines rely heavily on manual operations in the production process. For example, in the feeding process of materials, employees need to spend a lot of time and energy on the preparation and placement of materials. That is, when feeding, the gun barrels installed in the firecracker cake molds need to be taken out and placed in the material bin. This manual feeding method greatly restricts the improvement of production efficiency, making it difficult to achieve the operation mode of one person operating multiple machines, and thus it is difficult to form an obvious cost advantage in the fierce market competition. In addition, due to the problem of discontinuous material supply in manual feeding, the newly added materials lack proper restraint, and there may be a problem of disordered materials at the fault, which will not only affect the normal operation of the firecracker tying machine, resulting in a decline in the quality of tied firecrackers, but also may cause equipment failures and shutdowns, thereby further reducing production efficiency.

[0003] In summary, the existing firecracker tying machines face two significant challenges in the production process: high dependence on manual operations and the problem of disordered feeding. Based on this, the present application provides a feeding device for a firecracker tying machine, which realizes automatic feeding after filling the material bin, can effectively improve production efficiency, reduce the production efficiency of employees, and also reduce equipment failures and shutdown time caused by the problem of disordered materials.

[0030] Embodiment 1

[0031] This embodiment provides a feeding device for a knotting machine. As shown in the attached Figure 1 and the attached Figure 2 figures, it includes a feeding rack, a material bin 1, a material channel 2, a discharging bottom mold 3, a plug plate baffle mechanism 4, and a pushing mechanism 5, where:

[0032] The feeding rack is inclined and arranged at the feeding end of the whip knotting machine 100; the bin 1 is arranged on the feeding rack at the feeding end of the whip knotting machine for feeding the whip knotting machine; the material channel 2 is horizontally arranged above the bin 1 and is communicated with the bin, and the other end thereof serves as the feeding station; the discharging bottom die 3 is arranged at the feeding station for positioning the gun cake 200; the plug plate material blocking mechanism 4 is arranged between the discharging bottom die 3 and the material channel 2 for blocking the falling of the gun barrels in the material channel; the material pushing mechanism 5 is arranged below the discharging bottom die 3 for pushing the gun cake in the discharging bottom die into the material channel.

[0033] Preferably, the material channel 2 includes a side enclosure 2.1 at the top and a side enclosure at the bottom. Among them, the side enclosure at the top is composed of multiple elastic soft pressing strips and multiple vertical rods. The two ends of the soft pressing strip are fixed on the vertical rods. The soft pressing strip can specifically adopt a rubber strip, which applies a certain pressure to the materials in the material channel by its own weight to keep them in an orderly state. This constraint can prevent the upper-layer materials from scattering during the flowing process and ensure the stability and continuity of the material flow; the side enclosure at the bottom is equipped with a washboard pattern conveying device 10 for actively conveying the gun barrels to the bin.

[0034] Preferably, as shown in the attached Figure 2 figure, the discharging bottom die 3 is arranged on the feeding bottom plate of the feeding rack, and its shape matches the shape of the gun cake, and its height is lower than 1 / 2 of the gun barrel, and an opening is provided at its upper part as the outlet for the gun cake to be pushed out of the discharging bottom die. In this embodiment, the height of the discharging bottom die is designed to be lower than 1 / 2 of the gun barrel, which not only meets the positioning of the gun cake but also facilitates the material pushing mechanism to push out the gun cake.

[0035] Preferably, as shown in the attached Figure 2 figure to the attached Figure 4 figure, the plug plate material blocking mechanism 4 includes a plug plate 4.1 and a first electric push rod 4.2. The shape of the plug plate 4.1 and the discharging bottom die 3 together enclose a shape that is the same as the shape of the gun cake. The plug plate 4.1 movably penetrates through the feeding bottom plate of the feeding rack. The first electric push rod 4.2 is installed on the back of the feeding rack through a bracket, and its push rod is connected to the plug plate 4.1. Specifically, the plug plate is generally in the pushed-out state. After the discharging bottom die is filled with materials and before the material pushing mechanism pushes the materials, the plug plate retracts. At this time, the material pushing mechanism pushes, so that the materials in the discharging bottom die are pushed above the plug plate. When the material pushing mechanism retracts beyond the plug plate, the plug plate is pushed out to form a block for the materials.

[0036] Preferably, as shown in the attached Figure 2 figure and the attached Figure 4As shown in the figure, the pusher mechanism 5 includes guide shafts 5.1 provided on both sides of the blanking bottom die 3, pusher hinge plates 5.2 respectively slidably connected to the two guide shafts, a push rod 5.3 provided in the middle of the two pusher hinge plates 5.2, a linear module 5.4 for driving the push rod 5.3, and a second electric push rod 5.5 installed on the slide plate of the linear module 5.4. The setting height of the pusher hinge plate 5.2 is higher than that of the blanking bottom die 3. The two pusher hinge plates 5.2 are hinged to each other, and a chute 5.2.1 slidably connected to the guide shaft 5.1 is provided at the end of the pusher hinge plate 5.2 away from the hinge. The push rod 5.3 is fixedly installed on the slide plate of the linear module 5.4, and the push rod of the second electric push rod 5.5 is connected to the hinge shaft of the two pusher hinge plates 5.2. This design can use the linear module to push the gun cake out of the blanking bottom die upward, and at the same time, use the second electric push rod to change the two pusher hinge plates from a V shape to an inverted V shape, thereby realizing the stable pushing of the material and meeting the pushing of the special shape of the gun cake.

[0037] The feeding method using the above-mentioned feeding device for the knotting machine includes the following steps:

[0038] S1, Place the gun cake in the blanking bottom die and untie the cake; specifically, a gun cake tied with a plastic hoop can be used. After the gun cake is placed in the blanking bottom die, the plastic hoop is untied; the placement of the gun cake can be automatically performed using a mechanical claw.

[0039] S2, Control the pusher mechanism to push the gun cake out of the blanking bottom die until the gun cake exceeds the plug baffle mechanism;

[0040] S3, Control the pusher mechanism to reset. When the pusher mechanism runs below the plug baffle mechanism, the plug baffle mechanism acts to block the gun barrel in the material channel from falling;

[0041] S4, The pusher mechanism completes the reset. When a signal for pushing the next gun cake into the blanking bottom die is initiated, before pushing the gun cake, first control the plug baffle mechanism to reset, and then push the gun cake out. Repeat S2 and S3 in this way to realize the replenishment of materials from the bottom of the material channel of the knotting machine.

[0042] Specifically, during implementation, the storage bin and the material channel are pre-filled with materials. When replenishing materials, the gun cake is placed into the blanking bottom die manually or by a manipulator. Then, the plug of the plug baffle mechanism retracts, and at the same time, the pusher mechanism acts to stably push the material into the material channel. When the material reaches the predetermined limit height, after the pusher mechanism retracts below the plug, the plug is pushed out to lock the material in the current position to prevent the material from shifting or falling during subsequent operations. Then, the pusher mechanism resets to prepare for the next feeding operation. Through the above cycle process, the feeding device can efficiently realize the continuous transportation of materials, and each feeding operation follows the same steps, ensuring the stability and reliability of the operation.

[0043] In this embodiment, by placing the cake on the feeding bottom die and using the feeding mechanism to push the material upward, several barrels in the material channel move towards the silo. After one-time feeding, the material is blocked by the material blocking mechanism to prevent the material from falling. This feeding method of pushing the material upward from the bottom of the material channel can automatically replenish the material from the bottom without manual intervention, greatly reducing the manpower requirement and making it possible for one person to operate multiple devices simultaneously. This not only improves the production efficiency but also reduces the labor cost, with significant economic benefits.

[0044] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present invention.
