Description

Technical Field

[0001] The utility model relates to the technical field of paperboard production, in particular to a temperature and humidity control device for paperboard production. Background Art

[0002] In the process of cardboard production, the regulation of temperature and humidity is extremely important. Its core purpose is to ensure the quality of cardboard and significantly improve production efficiency. The precise control of temperature and humidity plays a key role in the quality of cardboard and the smoothness of production. The appropriate temperature can ensure the smooth progress of various chemical and physical changes in the production process and avoid unstable cardboard performance caused by improper temperature. Appropriate humidity helps to achieve good bonding between fibers, enhance the strength and flexibility of cardboard, and reduce quality problems such as breakage and deformation of cardboard during subsequent processing and use.

[0003] However, as far as the humidification devices commonly used in cardboard production are concerned, they generally rely on water pumps to achieve the humidification function. Usually, such humidification devices cannot form an effective linkage with other components on the production line. *For example, in order to achieve a comprehensive and uniform humidification effect, components such as nozzles connected to the water pump often need to be moved to spray water for humidification to ensure the humidification range. However, in actual situations, the mobile device and the water pump are usually set as two separate components. This leads to a series of problems. This separate design increases the difficulty of installation, maintenance and debugging of the equipment, which not only takes up more space, but also increases the cost investment. Moreover, the connection and communication between the two components are often not stable and reliable enough, and are prone to failure, affecting the stability and continuity of the entire production process. In order to improve it, a temperature and humidity control device for cardboard production is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 A temperature and humidity control device for cardboard production includes an installation frame 1 arranged in a cardboard production machine. The cardboard production machine is also provided with a temperature control device. This scheme only raises problems and improves the humidity control device. Therefore, this scheme does not draw the temperature control device and the cardboard production machine. The details of the above components can refer to the prior art. The humidity control device in this scheme can be installed in a suitable position by technicians in this technical field.

[0023] A moving screw 5 is provided on the installation frame 1 through a reciprocating motor 2, and a moving frame 6 is provided on the moving screw 5 through a threaded sleeve of a limiting mechanism. Two pump water tanks 10 are provided in the installation frame 1, and a water inlet pipe 9 connected to the pump water tank 10 is provided through the installation frame 1. The pump water tanks 10 are connected to the moving screw 5 through a moving mechanism. A rotating chamber 11 and a pump water chamber 12 are provided in the pump water tank 10, a piston plate 13 is provided in the pump water chamber 12, a lifting screw 14 is rotatably provided in the rotating chamber 11, the piston plate 13 is connected to the lifting screw 14 through a connecting mechanism, a rack 17 is provided in the installation frame 1, and the lifting screw 14 is connected to the rack 17 through a rotating mechanism.

[0024] The limiting mechanism includes a limiting rod 7 arranged in the installation frame 1. The limiting rod 7 is parallel to the moving screw 5. The limiting rod 7 slides through the moving frame 6. The function of the limiting rod 7 is to limit the moving frame 6 to prevent it from rotating with the moving screw 5.

[0025] The moving mechanism includes a water outlet pipe 8 connected to two pump water boxes 10, and the water outlet pipe 8 is fixedly connected to the moving frame 6. The water outlet pipe 8 is a hard pipe, which is connected to the moving frame 6, so that when the moving screw 5 rotates, it can drive the pump water box 10 and other components to move.

[0026] The connecting mechanism includes a connecting frame 15 threadedly mounted on the lifting screw 14. The connecting frame 15 is U-shaped and both ends are fixedly connected to the piston plate 13. Both ends of the connecting frame 15 slide through the inner wall of the rotating chamber 11 and extend into the water pump chamber 12. Therefore, it has its own limit and will not rotate with the lifting screw 14.

[0027] The rotating mechanism includes a gear 16 installed on the pump water box 10 and connected to the lifting screw 14, and the gear 16 is meshed with the rack 17. Since the gear 16 is meshed with the rack 17, when the pump water box 10 and other components move, the lifting screw 14 will rotate due to the above components.

[0028] The water inlet pipe 9 and the water outlet pipe 8 are both Y-shaped, and valves are arranged inside the water inlet pipe 9 and the water outlet pipe 8. Both valves are one-way valves. The design of the one-way valves ensures that water can only flow in one direction.

[0029] When the humidity needs to be increased, the reciprocating motor 2 is started and rotates forward and reversely, thereby driving the moving screw 5 to reciprocate forward and reversely. Since the limit rod 7 limits the moving frame 6, it is prevented from rotating with the moving screw 5, so that the moving frame 6 moves along the moving screw 5. The movement of the moving frame 6 drives the pump water box 10 to move together through the outlet pipe 8. Because the gear 16 on the pump water box 10 is meshed with the rack 17, when the pump water box 10 moves, the gear 16 rotates to drive the lifting screw 14 to rotate. When the lifting screw 14 rotates, the connecting frame 15 will not rotate with it because of its own limit, so that the connecting frame 15 drives the piston plate 13 to rise and fall in the pump water chamber 12. When the piston plate 13 rises, the one-way valve in the water inlet pipe 9 opens, and water is sucked into the pump water chamber 12; when the piston plate 13 descends, the one-way valve in the outlet pipe 8 opens, and water is squeezed out of the pump water chamber 12. Finally, it is sprayed out through the spray plate 3.

[0030] As shown in the figure, the present solution sets up two pump water tanks 10, and the initial positions of the two piston plates 13 are staggered up and down. Therefore, when one pump water tank 10 is performing a water discharge operation, the other pump water tank 10 is performing a water replenishment operation. The two pump water tanks 10 are used in combination to ensure that the spray plate 3 can always spray water for humidification operations.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
