Description

Technical Field

[0001] This invention relates to the field of corrugated cardboard processing technology, and more particularly to a dehumidification device for a corrugated cardboard production line. Background Technology

[0002] Corrugated cardboard, also known as corrugated paperboard, is made by bonding at least one layer of corrugated paper and one layer of linerboard (also called boxboard). It has good elasticity and extensibility and is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods. The manufacturing process of corrugated cardboard involves using hot glue to gelatinize the layers at high temperatures, forming an adhesive between them. When it first comes out of the stacker, the temperature of the corrugated cardboard is generally not lower than 50°C, and a large amount of water vapor accumulates in the gaps between the corrugated sections. The cardboard has not yet solidified. If the corrugated cardboard is not sufficiently dried and cooled before subsequent production processes, it will deform and collapse, thus reducing its edge crush strength. In existing corrugated cardboard production lines, dehumidifiers are typically installed on conveyor tables to dry the corrugated cardboard. These dehumidifiers are usually fixed in position, while the cardboard only moves along with the conveyor. Furthermore, the corrugated cardboard has corrugated channels, and simple surface airflow cannot completely remove moisture from these channels, resulting in poor dehumidification. The moisture remaining in the channels softens the cardboard, reduces its strength, and lowers its compressive strength, causing warping and unevenness, thus affecting quality. Therefore, a dehumidification device for corrugated cardboard production lines is needed. Summary of the Invention

[0003] The purpose of this invention is to provide a dehumidification device for a corrugated cardboard production line, solving the technical problems of existing dehumidification devices having poor dehumidification effects due to their inability to adjust position and their limitation to blowing air only onto the surface of the corrugated cardboard. The dehumidifier of this invention has a simple structure, can move its position according to the movement of the corrugated cardboard, and can dehumidify the corrugated channels within the cardboard, resulting in good dehumidification effect. The resulting corrugated cardboard is less prone to deformation, has stable strength, and good compressive strength.

[0004] High production efficiency.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A dehumidification device for a corrugated cardboard production line includes a workbench, a dehumidifier, a blower, a shrinkable air supply pipe, and a handle. The dehumidifier is located at one end of the workbench. The position of the dehumidifier is moved by the handle 5. The dehumidifier is fixedly connected to the workbench via a fixed rod and a rotating rod. The handle is located at one end of the rotating rod and is on the same side as the dehumidifier. The blower is located on one side below the workbench. The shrinkable air supply pipe is located directly below the workbench. One end of the shrinkable air supply pipe is connected to the dehumidifier, and the other end of the shrinkable air supply pipe is connected to the blower. The blower 3 provides cold air to the dehumidifier 2.

[0007] Furthermore, the workbench is fixed to the external ground with anchor bolts, and an electrical control box is installed on one side under the workbench. The electrical control box is connected to the blower via wires.

[0008] Furthermore, the dehumidifier includes an air inlet pipe, an air duct, and a housing. The lower end of the air inlet pipe is connected to a contraction air supply pipe, and the two sides of the upper end of the air inlet pipe are respectively connected to one end of the air duct. The other end of the air duct is connected to the housing. The bottom of the housing is respectively provided with a rotating rod connector and a fixing rod connector.

[0009] Furthermore, the housing consists of a bottom plate, a top plate, an end plate, and an arc-shaped plate. One end of the bottom plate and the top plate are respectively fixed to the end plate by welding. The other end of the top plate is fixed to one end of the arc-shaped plate by welding. A first air guide plate is welded to the other end of the arc-shaped plate. A second air guide plate is welded to one end of the first air guide plate. The second air guide plate is fixed to the top plate by welding. The first air guide plate is inclined and forms an air outlet with the bottom plate.

[0010] Furthermore, a rotating rod connecting seat is provided in the middle of the base plate, and fixed rod connecting seats are provided at both ends of the base plate. An air inlet is provided between the rotating rod connecting seat and the fixed rod connecting seat, and the air inlet is connected to the air guide pipe.

[0011] Furthermore, the rotating rod connector and the rotating rod connector are fixedly connected by hexagon socket head cap screws, and the fixed rod connector and the fixed rod connector are fixedly connected by hexagon socket head cap screws.

[0012] Furthermore, the fixed rod passes through the rotating rod connector, and both ends of the fixed rod are fixed to the worktable, with nuts fixed to the outer sides of both ends of the fixed rod; the rotating rod passes through the fixed rod connector, and both ends of the rotating rod are fixed to the worktable, with nuts fixed to the outer sides of both ends of the rotating rod, and the rotating rod is configured as a threaded rod.

[0013] Furthermore, the blower is fixed to the external ground by a blower support.

[0014] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0015] 1. This invention uses a blower to deliver cold air to a dehumidifier via a contraction air supply pipe. The cold air is then blown into the corrugated channels of the corrugated cardboard through the dehumidifier's outlet. The cold air carries away the hot air inside the corrugated channels, thus achieving a dehumidification effect. The resulting corrugated cardboard is less prone to deformation, has stable strength, and good compressive strength. It also reduces the heat that workers are exposed to during the corrugated cardboard recutting stage, increases the recutting speed, and improves production efficiency.

[0016] 2. This invention provides a handle at one end of the rotating rod, allowing the dehumidifier to be moved back and forth by rotating the handle; the retractable air supply duct can also move with the corrugated cardboard, thus satisfying the dehumidification needs of corrugated cardboard of various sizes.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the present invention, and these aspects of the invention can be implemented even without these specific details.

[0023] like Figure 1-3As shown, a dehumidification device for a corrugated cardboard production line includes a workbench 1, a dehumidifier 2, a blower 3, a shrink air supply pipe 4, and a handle 5. The dehumidifier 2 is mounted on one end of the workbench 1 and is fixedly connected to the workbench 1 via a fixed rod 6 and a rotating rod 7. There are two fixed rods 6 and one rotating rod 7, which is positioned between the two fixed rods 6. The handle 5 is mounted on one end of the rotating rod 7. By rotating the handle 5, the dehumidifier 2 can be moved back and forth via the rotating rod 7. The handle 5 and the dehumidifier 2 are located on the same side. The blower 3 is located on one side below the workbench 1. The shrink air supply pipe 4 is located directly below the workbench 1. One end of the shrink air supply pipe 4 is connected to the dehumidifier 2, and the other end is connected to the blower 3. The blower 3 provides cold air to the dehumidifier 2 and delivers the cold air into the dehumidifier 2 through the shrink air supply pipe 4. This invention features a blower 3 that delivers cool air to a dehumidifier 2 via a constricted air supply pipe 4. The cool air is then blown into the corrugated channels of the corrugated cardboard through the outlet of the dehumidifier 2. The cool air carries away the hot air inside the corrugated channels, thus achieving a dehumidification effect. The resulting corrugated cardboard is less prone to deformation, has stable strength, and good compressive strength. It also reduces the heat that workers are exposed to during the corrugated cardboard recutting stage, increases the recutting speed, and improves production efficiency.

[0024] like Figure 1 As shown, the workbench 1 is fixed to the external ground by anchor bolts 8 to ensure its stability during operation. An electrical control box 9 is installed on one side below the workbench 1. The electrical control box 9 is connected to the blower 3 via wires and controls the switching of the blower 3. The blower 3 is fixed to the external ground by a blower support 31, which is also fixed to the external ground by anchor bolts 8, ensuring stable operation of the blower 3.

[0025] like Figure 2 As shown, the dehumidifier 2 includes an air inlet pipe 21, an air guide pipe 22, and a housing 23. The lower end of the air inlet pipe 21 is connected to the shrink air supply pipe 4, which delivers cold air to the air inlet pipe 21. The two sides of the upper end of the air inlet pipe 21 are connected to one end of the air guide pipe 22, and the cold air in the air inlet pipe 21 enters the two side air guide pipes 22. The other end of the air guide pipe 22 is connected to the housing 23, and the air guide pipe 22 delivers cold air to the housing 23. The bottom of the housing 23 is provided with a rotating rod connector 24 and a fixed rod connector 25. The rotating rod connector 24 is used to fix the rotating rod 7, and the fixed rod connector 25 is used to fix the fixed rod 6.

[0026] like Figure 3As shown, the housing 23 consists of a bottom plate 231, a top plate 232, an end plate 233, and an arc-shaped plate 234. One end of the bottom plate 231 and the top plate 232 are respectively welded to the end plate 233. The other end of the top plate 232 is welded to one end of the arc-shaped plate 234. A first air guide plate 235 is welded to the other end of the arc-shaped plate 234. A second air guide plate 236 is welded to one end of the first air guide plate 235. The cold air in the dehumidifier 2 is guided to the first air guide plate 235 and the second air guide plate 236 through the first air guide plate 235 and the second air guide plate 236. Air outlet 237: Cold air is blown into the corrugated cardboard 11 through the air outlet 237, carrying away the hot air in the corrugated cardboard 11, thereby achieving a dehumidification effect (the water droplets formed by the instantaneous rapid cooling of the hot air adhere to places outside the production line). The second air guide plate 236 is fixed to the top plate 232 by welding. The first air guide plate 235 is set at an angle to ensure that the corrugated cardboard 11 can enter the air outlet 237 of the dehumidifier 2. The first air guide plate 235 and the bottom plate 231 form the air outlet 237. A rotating rod connecting seat 26 is provided in the middle of the base plate 231 for fixing the rotating rod connecting piece 24. Fixed rod connecting seats 27 are provided at both ends of the base plate 231 for fixing the fixed rod connecting piece 25. An air inlet 238 is provided between the rotating rod connecting seat 26 and the fixed rod connecting seat 27. The air inlet 238 is connected to the air guide pipe 22. The air guide pipe 22 sends cold air into the box 23 through the air inlet 238.

[0027] like Figure 1-2 As shown, the rotating rod connector 24 and the rotating rod connector 26 are fixedly connected by hexagon head screws 28, and the fixed rod connector 25 and the fixed rod connector 27 are fixedly connected by hexagon head screws 28. The fixed rod 6 passes through the rotating rod connector 24, and both ends of the fixed rod 6 are fixed to the workbench 1, with nuts 11 securing them to the outer sides of both ends. The rotating rod 7 passes through the fixed rod connector 25, and both ends of the rotating rod 7 are fixed to the workbench 1, with nuts 10 securing them to the outer sides of both ends. The rotating rod 7 is a threaded rod. The dehumidifier 2 is fixed to the workbench 1 by the fixed rod 6 and the rotating rod 7, and the nuts 10 at both ends ensure that the fixed rod 6 and the rotating rod 7 do not fall off.

[0028] Example

[0029] like Figure 4As shown, the dehumidification device is installed at the corrugated cardboard outlet on the production line. After the corrugated cardboard 11 comes out of the production line, one end of the corrugated cardboard 11 passes through the air outlet 237 of the dehumidifier 2. At this time, the blower 3 sends cold air into the dehumidifier 2 through the contraction air supply pipe 4. The dehumidifier 2 guides the cold air in the dehumidifier 2 to the air outlet 237 through the first air guide plate 235 and the second air guide plate 236. The cold air blows into the corrugated cardboard 11 through the air outlet 237, carrying away the hot air in the corrugated channel, thereby achieving the dehumidification effect. The corrugated cardboard 11 is effectively and quickly cooled at the air outlet 237, effectively reducing the heat that workers come into contact with during the reverse cutting stage of the production line, increasing the reverse cutting speed of the corrugated cardboard, and improving the production efficiency.

[0030] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
