Description
Technical Field
[0001] This utility model relates to the field of transfer device technology, specifically a transfer device for the production of fireworks that emit sparks. Background Technology
[0002] Fireworks that emit sparks have a unique jetting effect. When ignited, the sparklers are propelled into the sky and then explode. The combination of multiple colors effectively enhances the visual impact and increases the entertainment value, such as the common "Gatling gun" fireworks. During the preparation of these fireworks, the sparklers are processed into a bead shape using an adhesive, but care must be taken during transportation to prevent the sparklers from scattering due to stress.
[0003] Announcement No. CN 220103903 U discloses a transfer device for the production of sparkling fireworks. By using an air pump and an air bag in combination, an air cushion can be formed inside the shell to prevent the sparkling fireworks from tipping over during the transfer process. The spring can effectively reduce the bumps generated by the equipment during the transfer process and prevent the internal gunpowder from loosening during the movement and causing the tube to burst accidentally.
[0004] During the transport of sparkler-type fireworks, prolonged and continuous jolting can cause the sparklers to ignite due to friction and heat. The aforementioned application only addresses the issue of the sparklers scattering, but it cannot cool the sparklers to reduce the occurrence of spontaneous combustion, thus leaving the transport of sparkler-type fireworks still inadequate. Utility Model Content
[0005] The technical problem this invention aims to solve is to overcome existing defects and provide a transfer device for the production of sparkler-type fireworks. During the transfer process, the device not only buffers the sparkler-type fireworks to prevent them from scattering under stress, but also dissipates heat from the fireworks, preventing spontaneous combustion caused by frictional heat generated by prolonged continuous bumping, thus improving safety during transfer. At the same time, this transfer device can be used to adjust the height of the fireworks for picking up and placing, preventing collisions between fireworks due to excessive placement, which could affect the ignition effect of the sparklers. It also facilitates the removal of fireworks from the transfer device, effectively solving the problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a transfer device for the production of fireworks that produce sparklers, comprising a transfer vehicle and a storage box, wherein the storage box is fixed on the transfer vehicle, the upper side of the storage box is open, a support plate is slidably arranged inside the storage box, and the side of the support plate contacts the inner side of the storage box, an elastic support component for positioning the support plate is provided at the bottom of the inner cavity of the storage box, a connecting pipe communicating with the bottom of the inner cavity of the storage box is installed on the side of the support plate, a valve group is installed on the connecting pipe, and a one-way air intake component communicating with the bottom of the inner cavity of the storage box is installed on the side of the storage box.
[0007] As a preferred technical solution of this utility model, a jet box is installed on the upper side of the support plate, and jet ports are opened on both sides of the jet box. The end of the connecting pipe is fixed at the jet box and communicates with the inner cavity of the jet box.
[0008] As a preferred embodiment of this utility model, a sealing strip is fixed at the edge of the support plate, the sealing strip is in contact with the inner cavity of the storage box, the elastic support assembly is a spring assembly, the bottom end of the spring assembly is fixed to the bottom of the inner cavity of the storage box, and the top end of the spring assembly is in contact with the lower side of the support plate.
[0009] As a preferred embodiment of this utility model, the storage box is provided with a protective cover on the upper side to cover the opening, and the protective cover is detachable.
[0010] As a preferred embodiment of this utility model, the one-way air intake assembly includes an air intake pipe installed on the side of the storage box, and a one-way valve is installed on the air intake pipe.
[0011] As a preferred embodiment of this utility model, the end of the air inlet pipe is equipped with a connector that communicates with its inner cavity, the transfer vehicle is equipped with an air pump group, and the air outlet of the air pump group is equipped with a connecting pipe, which is snapped and fixed to the connector.
[0012] As a preferred technical solution of this utility model, an installation plate is slidably provided on the upper side of the transfer vehicle, an air pump unit is installed on the installation plate, and a guide plate is fixed on the upper side of the transfer vehicle to guide the movement of the installation plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The transfer device for producing sparkling fireworks according to this utility model, when the transfer vehicle is moved to a bumpy section, the support plate moves up and down under the force of the bumpy section, compressing the elastic support component. During this process, the elastic support component plays an elastic support role, reducing the force on the fireworks and preventing the sparkling beads inside the fireworks from being scattered due to force. Because the edge of the support plate is in contact with the inside of the storage box, air is drawn from the outside through the one-way air intake component when the support plate moves up, and when the support plate moves down, the air at the bottom of the storage box cavity is squeezed out through the connecting pipe. The airflow discharged through the connecting pipe drives the air flow in the storage box, reducing the heat generated by the friction between the sparkling beads when moving on the bumpy section, and reducing the occurrence of spontaneous combustion.
[0015] 2. The transfer device for producing fireworks of the present invention includes a protective cover placed at the opening during the transfer process to prevent the fireworks from falling out of the storage box through the opening. It should be noted that the protective cover does not need to be pressed tightly during the transfer process, so that the protective cover only serves to block and does not have a sealing function, which allows air to flow in the storage box. After the fireworks are transferred and need to be stored in the storage box for a long time, the protective cover is pressed tightly to block and seal the opening, reducing the impact of external temperature and humidity on the fireworks.
[0016] 3. The transfer device for producing sparkling fireworks according to this utility model connects the connecting pipe on the air pump group to the connector at the end of the air inlet pipe. The air pump group is controlled to operate, and the air pump group draws air from the outside. The drawn air enters the storage box through the air inlet pipe, improving the heat dissipation efficiency of the fireworks in the storage box. When taking fireworks out of the storage box, the valve group is closed, and the gas entering the storage box is no longer discharged. The gas pushes the support plate to gradually move upward, making it easier to take out the fireworks at the bottom of the storage box. When placing fireworks into the storage box, the support plate is also adjusted to move upward, reducing the falling height of the fireworks in the storage box and preventing the fireworks from falling too high, which would cause the sparkling fireworks to scatter due to force, thus ensuring the quality of the fireworks.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-6 This utility model provides a technical solution: a transfer device for the production of sparkling fireworks, including a transfer vehicle 1 and a storage box 2. A push handle is provided at the front of the transfer vehicle 1, and four sets of universal wheels are installed at the bottom of the transfer vehicle 1. The four sets of universal wheels are located below the four corners of the transfer vehicle 1. The push handle pushes the transfer vehicle 1 to move the storage box 2, which facilitates the transfer of sparkling fireworks in the storage box 2. The storage box 2 is fixed on the transfer vehicle 1. The upper side of the storage box 2 is open, which facilitates the storage of fireworks in the storage box 2. A support plate 4 is slidably installed inside the storage box 2. The support plate 4 is used for supporting and limiting the fireworks, and the side of the support plate 4 contacts the inner side of the storage box 2. An elastic support component for positioning the support plate 4 is provided at the bottom of the inner cavity of the storage box 2. A connecting pipe 7 connected to the bottom of the inner cavity of the storage box 2 is installed on the side of the support plate 4. A valve group 8 is installed on the connecting pipe 7. A one-way air intake component connected to the bottom of the inner cavity of the storage box 2 is installed on the side of the storage box 2.
[0026] When transporting fireworks, as the transport vehicle 1 moves to a bumpy section, the support plate 4 moves up and down under the force of the bumpy road, compressing the elastic support component. During this process, the elastic support component provides elastic support, reducing the force on the fireworks and preventing the fireworks beads inside from scattering. Because the edge of the support plate 4 is in contact with the inside of the storage box 2, air is drawn from the outside through the one-way air intake component when the support plate 4 moves upward, and when the support plate 4 moves downward, the air at the bottom of the inner cavity of the storage box 2 is squeezed out through the connecting pipe 7. The airflow discharged through the connecting pipe 7 drives the air flow inside the storage box 2, reducing the heat generated by friction between the fireworks beads when moving on the bumpy road and reducing the occurrence of spontaneous combustion.
[0027] A jet box 6 is installed on the upper side of the support plate 4. Jet ports are opened on both sides of the jet box 6. The end of the connecting pipe 7 is fixed at the jet box 6 and communicates with the inner cavity of the jet box 6. After the support plate 4 moves down and squeezes the air at the bottom of the inner cavity of the storage box 2 into the connecting pipe 7, the connecting pipe 7 delivers the gas to the jet box 6 and sprays it out through the jet port on the side of the jet box 6. The jet port is designed to increase the jet area, thereby increasing the heat dissipation area and facilitating the use of this transfer device.
[0028] A sealing strip 5 is fixed at the edge of the support plate 4. The sealing strip 5 contacts the inner cavity of the storage box 2. The sealing strip 5 improves the sealing performance when the edge of the support plate 4 contacts the inner side of the storage box 2, which facilitates the suction and discharge of air during the up and down movement of the support plate 4, and facilitates the buffering and heat dissipation function during the transfer of fireworks.
[0029] The storage box 2 is equipped with a protective cover 3 on the upper side to cover the opening. The protective cover 3 is detachable. During transportation, the protective cover 3 is placed at the opening to cover it, preventing fireworks from falling out of the storage box 2 through the opening. It should be noted that the protective cover 3 does not need to be pressed tightly during transportation, so that the protective cover 3 only serves to cover and does not have a sealing function, allowing air to flow in the storage box 2. After the fireworks are transported and need to be stored in the storage box 2 for a long time, the protective cover 3 is pressed tightly to cover and seal the opening, reducing the impact of external temperature and humidity on the fireworks.
[0030] The one-way air intake assembly includes an air intake pipe 10 installed on the side of the storage box 2. A one-way valve 11 is installed on the air intake pipe 10. When the support plate 4 moves upward in the storage box 2, the storage box 2 draws air from the outside through the air intake pipe 10. The one-way valve 11 is a one-way air intake valve. When the support plate 4 moves downward in the storage box 2, the support plate 4 cannot compress the air through the air intake pipe 10 due to the action of the one-way valve 11, ensuring that the gas enters the jet box 6 through the connecting pipe 7 to play a role in heat dissipation.
[0031] The end of the air inlet pipe 10 is equipped with a connector 12 that communicates with its inner cavity. The transfer vehicle 1 is equipped with an air pump group 14. A connecting pipe 15 is provided at the air outlet of the air pump group 14. The connecting pipe 15 is snapped and fixed to the connector 12. The connecting pipe 15 on the air pump group 14 is connected to the connector 12 at the end of the air inlet pipe 10 to control the operation of the air pump group 14. The air pump group 14 draws air from the outside, and the drawn air enters the storage box 2 through the air inlet pipe 10 to improve the heat dissipation efficiency of the fireworks in the storage box 2. When taking out or putting out fireworks in the storage box 2, the valve group 8 is closed, and the gas entering the storage box 2 is no longer discharged. The gas pushes the support plate 4 to gradually move upward, making it easier to take out the fireworks at the bottom of the storage box 2. When putting fireworks into the storage box 2, the support plate 4 is also adjusted to move upward to reduce the falling height of the fireworks in the storage box 2 and prevent the fireworks from falling too high, which would cause the fireworks to scatter due to force and ensure the quality of the fireworks. When it is not necessary to adjust the movement of the support plate 4, the valve group 8 is opened, and the gas is discharged through the connecting pipe 7 for the heat dissipation of the fireworks.
[0032] A mounting plate 13 is slidably mounted on the upper side of the transfer vehicle 1. An air pump assembly 14 is mounted on the mounting plate 13. A guide plate 16 is fixed on the upper side of the transfer vehicle 1 to guide the movement of the mounting plate 13. The position of the air pump assembly 14 can be adjusted by moving the mounting plate 13, which facilitates the connection or disassembly of the connecting pipe 15 and the connector 12 on the air pump assembly 14, and makes it easy to use the air pump assembly 14 as needed. During the movement of the mounting plate 13, the guide plate 16 plays a positioning and guiding role. The guide plate 16 is used to limit the mounting plate 13 and the air pump assembly 14 on the mounting plate 13.
[0033] The elastic support assembly is a spring group 9. The bottom end of the spring group 9 is fixed to the bottom of the inner cavity of the storage box 2, and the top end of the spring group 9 contacts the lower side of the support plate 4. The spring group 9 provides elastic support for the support plate 4, which facilitates the support plate 4 to move up and down after being subjected to force. The support plate 4 and the spring group 9 are connected separately, which facilitates the control of the air pump group 14 to work and deliver air to push the support plate 4 to move upward in the storage box 2.
[0034] The valve assembly 8 and air pump assembly 14 used in this utility model are common electronic components in the prior art. Their working methods and circuit structures are known technologies. The operation of electronic components such as valve assembly 8 and air pump assembly 14 is controlled by setting a switch group or PLC controller on the transfer car 1. This method is a common technical means used by technicians and will not be described in detail here.
[0035] This transfer device for producing sparkler-type fireworks not only buffers the sparkler-type fireworks during the transfer process to prevent them from scattering under stress, but also helps dissipate heat from the sparkler-type fireworks, preventing spontaneous combustion caused by frictional heat generated during prolonged continuous bumping, thus improving safety during transfer. At the same time, this transfer device can be used to adjust the height of the fireworks for picking up and placing, avoiding collisions between fireworks that may affect the ignition effect due to placement at too deep a position, and also making it easier to remove the fireworks from this transfer device.

Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
