Description

Technical Field

[0001] This utility model relates to the field of paper tube production and drying technology, and more specifically, to a dryer for paper tube production and processing. Background Technology

[0002] Fireworks, also known as sparklers, fireworks, or firecrackers, are defined in the "Chinese Fireworks and Firecrackers Standard—Safety and Quality" as: entertainment products made from gunpowder to produce sound, light, and color. They were invented relatively early by the Chinese working people and are often used in grand ceremonies or performances. In the manufacturing process, combination fireworks are made by assembling individual paper tubes with glue to create a combination firework assembly of the required specifications. The assembled fireworks then undergo steps such as clay pressing and gunpowder filling. However, the assembly assembly requires the application of glue during preparation and needs to be stored for a period of time after completion. Due to the humid climate in southern regions, the assembly assembly is easily affected by moisture. To ensure the quality of the gunpowder after filling, the paper tubes need to be dried before gunpowder filling.

[0003] Chinese Patent Publication No. CN215295693U discloses an environmentally friendly fully automatic energy-saving paper tube dryer for fireworks and firecrackers. It heats the outer wall of the fixed tube by heating wire, which can heat the inner wall of the paper tube sleeved on the fixed tube, thereby increasing the drying efficiency of the paper tube. The funnel can collect the debris that falls on the paper tube, and then discharge the collected debris through the trough, so as to avoid the debris falling into the corners inside the dryer and making it inconvenient for the operator to clean.

[0004] While the aforementioned patents can increase the drying efficiency of paper tubes to some extent, they can only improve the drying efficiency of a single paper tube and cannot be adapted to multi-tube fireworks paper tubes with specifications of 6x6 or more, thus having certain limitations in practical use. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a dryer for paper tube production and processing. It can position the firework assembly basin through a guide plate and a driven rotating plate, and push the air guide plate downward through an electric push rod to insert the guide tube into the gap between the tubes. While hot air fills the drying chamber, more airflow can be delivered to the gap between the tubes, thereby greatly improving the drying efficiency of the assembly firework paper tube.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A drying machine for paper tube production includes a workbench and a drying chamber, which are integrally formed. A conveying mechanism is installed on the workbench, with an inlet and a outlet at its front and rear ends, respectively. The inlet periodically conveys firework tube sets into the drying chamber. The gap between the paper tubes in each firework tube set is the tube gap. An air supply chamber is installed on the side wall of the drying chamber, containing a heating wire and a fan. The drying chamber has interconnected drying compartments, an air inlet compartment, and an assembly slot. A guide pipe is fixedly connected to the air supply chamber, with its other end connected to the air inlet compartment. A guide plate is slidably connected within the assembly slot, with a guide pipe fixedly connected to its lower end. The upper end of the assembly slot is connected to... Multiple electric push rods and compression springs are respectively provided at the inner bottom end. The power output end of the electric push rod and the end of the compression spring that are close to each other are fixedly connected to the air guide plate. A pair of guide plates are fixedly connected inside the drying chamber. A driven rotating plate is rotatably connected to the guide plate. A pair of electric push rods are provided at the inner bottom end of the drying chamber. The pair of electric push rods are located on the left and right sides of the conveying mechanism. The power output end of the electric push rod is fixedly connected to the driven rotating plate. The firework assembly can be positioned by the guide plate and the driven rotating plate. The air guide plate is pressed downward by the electric push rod, so that the guide tube is inserted into the gap between the tubes. While the hot air fills the drying chamber, more airflow can be delivered to the gap between the tubes, thereby greatly improving the drying efficiency of the assembly type firework paper tube.

[0010] Furthermore, the air intake chamber is a chamber that is wider at the top and narrower at the bottom, and the air guide plate is located on the lower side of the air intake chamber, making it easier for hot air to be blown along the inner wall of the air intake chamber to the drying chamber.

[0011] Furthermore, multiple guide pipes are provided, and these multiple guide pipes are arranged in a ring array on the air guide plate. The number and arrangement specifications of the guide pipes are matched with the gap between the pipes. More hot air can be blown into the gap between the pipes through the guide pipes, thereby improving the drying rate of the gap between the pipes.

[0012] Furthermore, there are four electric push rods and four compression springs, which are distributed at the upper and lower corners of the air guide plate to provide stability for the air guide plate to slide up and down in the assembly groove.

[0013] Furthermore, the guide plate includes a guide section and a longitudinal section. The guide section is an obliquely arranged plate, and the distance between a pair of guide plates gradually decreases from the side closer to the feed inlet to the side closer to the discharge outlet. The length of the longitudinal section is half that of the guide section, and the distance between a pair of longitudinal sections matches the size specifications of the fireworks assembly. In its natural state, the driven rotating plate forms a 90° angle with the power output end of the electric push rod two. After the fireworks assembly enters the drying chamber from the feed inlet, the guide section, the longitudinal section, and the driven rotating plate on the guide plate work together to move the fireworks assembly to a suitable position. At this position, the guide pipe is exactly above the gap between the pipes, which facilitates the subsequent drying process.

[0014] 3. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] (1) This solution can position the firework assembly by means of the guide plate and the driven rotating plate, and push the air guide plate downward by means of the electric push rod, so that the guide tube is inserted into the gap between the tubes. While the hot air fills the drying chamber, more flowing air can be delivered to the gap between the tubes, thereby greatly improving the drying efficiency of the assembly type firework paper tube.

[0017] (2) The air inlet chamber is a chamber that is wider at the top and narrower at the bottom. The air guide plate is located on the lower side of the air inlet chamber, making it easier for hot air to blow along the inner wall of the air inlet chamber to the drying chamber.

[0018] (3) Multiple guide pipes are set, and the multiple guide pipes are arranged in a ring array on the air guide plate. The number and arrangement specifications of the guide pipes are matched with the gap between the pipes. More hot air can be blown into the gap between the pipes through the guide pipes, thereby improving the drying rate of the gap between the pipes.

[0019] (4) There are four electric push rods and four compression springs, and the four electric push rods and four compression springs are respectively distributed at the upper and lower corners of the air guide plate to provide stability for the air guide plate to slide up and down in the assembly slot.

[0020] (5) The guide plate includes a guide section and a longitudinal section. The guide section is an obliquely arranged plate, and the distance between a pair of guide plates gradually shortens from the side closer to the feed inlet to the side closer to the discharge outlet. The length of the longitudinal section is half that of the guide section, and the distance between a pair of longitudinal sections matches the size and specifications of the fireworks assembly. In its natural state, the driven rotating plate forms a 90° angle with the power output end of the electric push rod 2. After the fireworks assembly enters the drying chamber from the feed inlet, the guide section, the longitudinal section and the driven rotating plate on the guide plate work together to move the fireworks assembly to a suitable position. At this position, the guide pipe is just above the gap between the pipes, which facilitates the subsequent drying process. Attached Figure Description

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Example 1:

[0033] Please see Figure 1-6 A paper tube production and processing dryer includes a workbench 1 and a drying chamber 2, which are integrally formed. A conveying mechanism is provided on the workbench 1, with an inlet 101 and an outlet 102 at its front and rear ends, respectively. The inlet 101 periodically conveys firework assembly trays 3 into the drying chamber 2. The gap between the paper tubes on the firework assembly trays 3 is a tube gap 301. An air supply chamber 4 is provided on the side wall of the drying chamber 2, containing an electric heating wire 5 and a fan 6. The conveying mechanism, the electric heating wire 5, and the fan 6 are all prior art known to those skilled in the art and will not be described in detail here. The drying chamber 2 has interconnected drying chambers 201, air inlet chambers 202, and assembly slots 203. A fixed connection is provided on the air supply chamber 4. A guide pipe 7 is connected to the air inlet chamber 202. A guide plate 8 is slidably connected in the assembly groove 203. The guide plate 8 is provided with a mesh distributed in a rectangular array. A guide pipe 9 is fixedly connected to the lower end of the guide plate 8. Multiple electric push rods 10 and compression springs 11 are respectively provided at the top and bottom of the assembly groove 203. The power output end of the electric push rod 10 and the end of the compression spring 11 that are close to each other are fixedly connected to the guide plate 8. A pair of guide plates 12 are fixedly connected in the drying chamber 201. A driven rotating plate 13 is rotatably connected to the guide plate 12. A pair of electric push rods 14 are provided at the bottom of the drying chamber 201. The pair of electric push rods 14 are located on the left and right sides of the conveying mechanism. The power output end of the electric push rods 14 is fixedly connected to the driven rotating plate 13.

[0034] It is worth noting that the opening and closing of the conveying mechanism, electric push rod 10, and electric push rod 24 can be controlled by an external program. For example, when the fireworks tray 3 is placed on the conveying mechanism, after it enters the drying chamber 201 for 8-10 seconds, the front end of the fireworks tray 3 abuts against the driven rotating plate 13. At this time, the conveying mechanism stops running, and electric push rod 10 is started. Its power output end extends and drives the air guide plate 8 to press down until part of the guide tube 9 is submerged in the tube gap 301. After this process lasts for 45-60 seconds, the drying process of the fireworks tray 3 is completed, electric push rod 10 stops running, and the compression spring 11 drives the air guide plate 8 and the guide tube 9 to reset. Then, electric push rod 24 is started. The power output end of electric push rod 214 extends and drives the driven rotating plate 13 to rotate upward, so that the driven rotating plate 13 separates from the fireworks tray 3. Then the conveying mechanism restarts and drives the fireworks tray 3 to move towards one end of the discharge port 102.

[0035] Please see Figure 2 The air intake chamber 202 is a chamber that is wider at the top and narrower at the bottom. The air guide plate 8 is located on the lower side of the air intake chamber 202, which makes it easier for hot air to be blown along the inner wall of the air intake chamber 202 to the drying chamber 201.

[0036] Please see Figure 3-4 Multiple guide pipes 9 are provided, and the multiple guide pipes 9 are arranged in a ring array on the air guide plate 8. The number and arrangement specifications of the guide pipes 9 are matched with the gap between pipes 301. More hot air can be blown into the gap between pipes 301 through the guide pipes 9, thereby improving the drying rate of the gap between pipes 301.

[0037] Please see Figure 3-6 There are four electric push rods 10 and four compression springs 11, and the four electric push rods 10 and compression springs 11 are respectively distributed at the upper end and the four corners of the lower end of the air guide plate 8, so as to provide stability for the air guide plate 8 to slide up and down in the assembly groove 203.

[0038] Please see Figure 3-4 The guide plate 12 includes a guide section and a longitudinal section. The guide section is an obliquely arranged plate, and the distance between a pair of guide plates 12 gradually decreases from the side near the feed inlet 101 to the side near the discharge outlet 102. The length of the longitudinal section is half that of the guide section, and the distance between a pair of longitudinal sections matches the size and specifications of the fireworks assembly 3. In its natural state, the driven rotating plate 13 forms a 90° angle with the power output end of the electric push rod 14. After the fireworks assembly 3 enters the drying chamber 2 through the feed inlet 101, the guide section, the longitudinal section and the driven rotating plate 13 on the guide plate 12 can work together to move the fireworks assembly 3 to a suitable position. At this position, the guide pipe 9 is just above the pipe gap 301, which facilitates the subsequent drying process.

[0039] When using this invention, the heating wire 5 and the fan 6 are initially in operation. First, the fireworks assembly 3 is placed on the conveying mechanism and allowed to enter the drying chamber 201 along the conveying mechanism. The guide plate 12 limits the movement trajectory of the fireworks assembly 3, allowing it to continue moving forward and abut against the driven rotating plate 13. At this time, the guide pipe 9 is located directly above the gap 301 between the pipes. The conveying mechanism is paused, and the electric push rod 10 is activated. Its power output end extends, causing the air guide plate 8 to press down until part of the guide pipe 9 is submerged in the gap 301 between the pipes, allowing the hot air filling the drying chamber 2 to flow more rapidly. The airflow dries the surface of the firework tray 3 and the gap 301 between the tubes. After drying, the electric push rod 10 stops running, the compression spring 11 drives the air guide plate 8 and the guide pipe 9 to reset the guide pipe 9, and the electric push rod 2 14 is started. The power output end of the electric push rod 2 14 extends and drives the driven rotating plate 13 to rotate upward, so that the driven rotating plate 13 separates from the firework tray 3. Finally, the conveying mechanism restarts and transports the firework tray 3 to the outside. Compared with the prior art, this utility model can realize that while hot air fills the drying chamber, more flowing air can be delivered to the gap between the tubes, thereby greatly improving the drying efficiency of the tray-type firework paper tube.

[0040] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
