Description

Technical Field

[0001] This utility model relates to the field of impregnated paper production technology, specifically a drying oven for impregnated paper production. Background Technology

[0002] Melamine-impregnated paper, also known as melamine-impregnated paper or simply melamine paper, refers to offset paper made by impregnating solid-color base paper or printed decorative paper with amino resin, and then drying it to a certain extent before hot pressing and bonding it to a wood-based panel substrate.

[0003] Currently, the drying of impregnated paper is generally carried out by conventional methods such as hot air drying and heated roller drying. For example, Chinese Patent No. CN214401211U discloses a rapid semi-drying device for impregnated paper production, which includes a conveyor table and a base. The front and back of the conveyor table are fixedly provided with mutually symmetrical side plates. The top surface of the side plates is fixedly connected with mutually symmetrical mounting blocks. A first electromagnetic heating roller is provided between two mounting blocks on the same side through a roller shaft. A second electromagnetic heating roller is provided between two mounting blocks away from the first electromagnetic heating roller through a roller shaft. The end of the roller shaft of the first electromagnetic heating roller near the base passes through the mounting block on the same side and is fixedly connected to a first gear. A first rotating wheel is fixedly connected to the center of the front of the first gear.

[0004] The drying device uses two electromagnetic heating rollers to dry the varnished paper. However, the device can only dry one side, which can easily lead to the varnished paper being wet inside after the surface has reached the drying requirements. When drying continues, carbonization can easily occur on the surface of the varnished paper, resulting in limited drying effect. Therefore, we propose a drying box for varnished paper production to solve the above problems. Utility Model Content

[0019] 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.

[0020] Example 1

[0021] Reference Figure 1 , 2 This is the first embodiment of the present invention. This embodiment provides a drying box for the production of impregnated paper, including a drying box 2. One end of the drying box 2 is fixedly connected to a transmission frame 1, and the other end of the drying box 2 is fixedly connected to a transmission frame 2 3. Two connecting pipes 7 are provided between the transmission frames 1 and 2. Several air nozzles 8 are fixedly connected to the side of the two connecting pipes 7 away from the drying box 2. One end of the two connecting pipes 7 is fixedly connected to a drive assembly 9, which is located on one side of the transmission frame 1. The other end of the two connecting pipes 7 is fixedly connected to one end of a support frame 6. The support frame 6 is slidably connected to the other side of the transmission frame 1. The top of the middle part of the support frame 6 is connected to one end of a connector 5 through a threaded structure. The other end of the connector 5 is connected to a blower 4 through a pipeline. The blower 4 is fixedly installed outside the drying box 2.

[0022] Several lower fans 14 are fixedly installed at the bottom of the drying chamber 2. The top of the lower fans 14 is fixedly connected to the lower heating mesh 13. The upper drying components 11 are fixedly connected to the top of the drying chamber 2 on both sides of the top of the lower heating mesh 13. An exhaust fan 12 is provided between the upper drying components 11 and is fixedly connected to the top of the drying chamber 2.

[0023] The sizing paper requiring drying is conveyed via conveyor frame 1. The sizing paper enters through rectangular openings on both sides of the drying chamber 2. After drying, it is conveyed and wound via conveyor frame 3. A blower 4, connected to an air pipe and connector 5, is used. The support frame 6 has a U-shaped structure with hollow interior air channels, which are connected to connector 5 and connecting pipe 7. When blower 4 is powered on, it fills the connecting pipe 7 with gas, which is then blown out through nozzle 8. Nozzle 8 dries the liquid on the surface of the sizing paper, facilitating subsequent drying in the drying chamber 2. The blown-out liquid falls into the drying chamber under gravity. The paper is collected in the collection tank 10. The upper drying component 11, exhaust fan 12, lower heating grid 13, and lower fan 14 are powered on. The upper drying component 11 blows hot air towards the top surface of the impregnated paper to dry the upper surface of the impregnated paper. The lower fan 14, in conjunction with the lower heating grid 13, blows hot air towards the bottom surface of the impregnated paper to dry the lower surface of the impregnated paper. This double-sided drying method improves the drying effect of the impregnated paper. At the same time, the drying water vapor is discharged from the drying chamber 2 through the exhaust fan 12 to avoid water vapor accumulation and moisture absorption of the impregnated paper, and to prevent the impregnated paper from being damaged by excessive water vapor.

[0024] Example 2

[0025] Reference Figure 1-3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, a transmission roller 101 is rotatably installed on both sides of the transmission frame 1. The connecting pipe 7 is located on the top of the transmission roller 101. The sizing paper to be dried is transmitted through the transmission roller 101 of the transmission frame 1. The sizing paper enters through rectangular openings on both sides of the drying box 2. The top of the connecting pipe 7 allows the air nozzle 8 to blow gas toward the sizing paper.

[0026] Furthermore, a second transmission roller 31 is rotatably installed between the two transmission frames 3, and guide rollers 21 are rotatably installed on both sides inside the drying box 2. The axes of the first transmission roller 101, the second transmission roller 31 and the guide roller 21 are set on the same plane. The setting on the same plane ensures the stability of the impregnated paper transmission.

[0027] Specifically, the air nozzle 8 is set at an angle downwards towards the side away from the drying chamber 2, and the air nozzles 8 on the two connecting pipes 7 are staggered. The staggered air nozzles 8 can fully cover the impregnated paper when the two connecting pipes 7 move back and forth.

[0028] Specifically, a collection pool 10 is fixedly installed at the bottom between the transmission racks 1 and 2, and the collection pool 10 collects the blown-down liquid.

[0029] Specifically, the drive assembly 9 includes a mounting base 91, a servo motor 92, a turntable 93, a cylindrical pin 94, a transmission frame 95, and a slide rod 96. The mounting base 91 is fixedly connected to one side of the outer wall of the transmission frame 1. The top of the mounting base 91 is fixedly connected to the servo motor 92. The output shaft of the servo motor 92 is coaxially fixedly connected to one end of the turntable 93. The other end of the turntable 93 is eccentrically connected to the cylindrical pin 94. The cylindrical pin 94 is slidably engaged with the transmission frame 95. The transmission frame 95 is movably mounted on the top of the turntable 93, and both ends of the transmission frame 95 are respectively fixedly connected to one end of the slide rod 96. The slide rod 96 is slidably engaged with the transmission frame 1. The end of the slide rod 96 away from the transmission frame 95 is respectively fixedly connected to the end of the connecting pipe 7.

[0030] When the servo motor 92 of the drive assembly 9 is powered on, the servo motor 92 drives the turntable 93 to rotate in a circle. The turntable 93 drives the cylindrical pin 94 to rotate in a circle. The cylindrical pin 94 drives the transmission frame 95, which is slidably engaged, to move back and forth in a linear motion. The transmission frame 95 drives the slide rods 96, which are fixed at both ends, to move back and forth in a linear motion in a synchronous manner. The slide rods 96 then drive the fixed connecting pipe 7 to move back and forth in a linear motion. The connecting pipe 7 drives the fixed air nozzles 8 to move back and forth in a linear motion. The air nozzles 8 on the two connecting pipes 7 then swing alternately to blow on the impregnated paper, preventing a single air nozzle 8 from blowing on one place and avoiding damage to the impregnated paper.

[0031] Specifically, the upper drying assembly 11 includes a filter screen 111, an upper fan 112, and an upper heating grid 113. The upper fan 112 is fixedly connected to the top two sides of the drying chamber 2, with the filter screen 111 fixedly connected to the top of the upper fan 112 and the upper heating grid 113 fixedly connected to the bottom of the upper fan 112. The upper heating grid 113 is fixedly installed inside the drying chamber 2. The upper fan 112 of the upper drying assembly 11, in conjunction with the upper heating grid 113, blows hot air toward the top surface of the impregnated paper, thereby drying the upper surface of the impregnated paper.

[0032] Example 3

[0033] Reference Figure 1-3This is the third embodiment of the present invention. Based on the above two embodiments, in use, the sizing paper to be dried is transported by the transport roller 101 of the transport frame 1. The sizing paper enters through rectangular openings on both sides of the drying chamber 2. After drying, it is transported and wound by the transport roller 31 of the transport frame 3. The blower 4 is connected to the air pipe and the connector 5. The support frame 6 has a U-shaped structure and is hollow inside with air channels. The air channels are connected to the connector 5 and the connecting pipe 7 respectively. When the blower 4 is powered on, it fills the connecting pipe 7 with gas. The gas is finally blown out through the air nozzle 8, which then dries the liquid on the surface of the sizing paper, facilitating the subsequent drying operation in the drying chamber 2. At the same time, the servo motor 92 of the drive component 9 is powered on. The servo motor 92 drives the turntable 93 to rotate circumferentially. The turntable 93 drives the cylindrical pin 94 to rotate circumferentially. The cylindrical pin 94 drives the sliding transmission frame 95 to move back and forth linearly. The transmission frame 95 drives the slide rod 9 fixed at both ends. The synchronous reciprocating linear movement of the slide bar 96 drives the fixed connecting pipe 7 to reciprocate, and the connecting pipe 7 drives the fixed air nozzle 8 to reciprocate linearly. The air nozzle 8 then blows the impregnated paper in an alternating manner to prevent a single air nozzle 8 from blowing on one place and to avoid damage to the impregnated paper. The blown liquid falls into the collection pool 10 for collection under the action of gravity. The upper drying component 11, the exhaust fan 12, the lower heating grid 13, and the lower fan 14 are powered on and work. The upper fan 112 of the upper drying component 11, together with the upper heating grid 113, blows hot air toward the top surface of the impregnated paper to dry the upper surface of the impregnated paper. The lower fan 14, together with the lower heating grid 13, blows hot air toward the bottom surface of the impregnated paper to dry the lower surface of the impregnated paper. The double-sided drying method improves the drying effect of the impregnated paper. At the same time, the drying water vapor is discharged from the drying box 2 through the exhaust fan 12 to avoid water vapor accumulation and moisture damage to the impregnated paper.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
