Description

Technical Field

[0001] The utility model relates to the technical field of paper machines, in particular to a paper drying device. Background Technique

[0002] In the modern paper-making industry and related paper processing fields, paper drying is a crucial link. For example, the patent with the publication number CN216107817U discloses a paper drying device, which improves the drying efficiency by arranging drying devices on both the upper and lower sides of the paper and heating from both the upper and lower sides of the paper.

[0003] However, it is found in the actual drying process that since the paper is driven by the two-end winding machines and moves too fast, the drying time is short, which affects the drying effect to a certain extent. Moreover, due to the limitation of the heating area of the drying device, the drying area of the paper is small. Content of the Utility Model

[0004] In order to solve the problem that the drying time of the existing paper is short and affects the drying effect, the utility model provides a paper drying device. By arranging the upper air outlet and the lower air outlet alternately, the paper placed in the drying channel is conveyed in a wavy shape, which prolongs the drying time and ensures the drying effect.

[0005] The utility model provides a paper drying device, which includes a frame. The frame has a paper inlet and a paper outlet. An upper air supply group and a lower air supply group are arranged in the frame. A drying channel connecting the paper inlet and the paper outlet is formed between the upper air supply group and the lower air supply group. Both the upper air supply group and the lower air supply group are composed of a plurality of air outlets. The plurality of air outlets are arranged along the length direction of the drying channel. The air outlets of the upper air supply group and the air outlets of the lower air supply group are arranged alternately. Through the alternately arranged upper and lower air outlets, the paper placed in the drying channel is conveyed in a wavy shape, which prolongs the drying time and ensures the drying effect.

[0006] Further, a wind blocking mechanism is arranged on the air outlet for adjusting the air volume. The air outlet is blocked by the wind blocking mechanism to adjust the air volume.

[0007] Further, the wind blocking mechanism includes a wind blocking plate and a push rod. An extension frame is arranged on one side of the air outlet. The wind blocking plate moves horizontally along the extension frame through the push rod. The extension frame is used for installing the wind blocking plate and the push rod. The air outlet is blocked by adjusting the wind blocking plate through the push rod.

[0008] Further, a guiding strip is also arranged on the side of the air outlet close to the extension frame. The wind blocking plate passes through the guiding strip and extends above the air outlet. The wind blocking plate is guided by the guiding strip to smoothly extend above the air outlet to change the width of the air outlet.

[0009] Furthermore, a push plate is provided at the movable end of the push rod. The wind shield is composed of several strip plates spliced together. The length direction of the strip plates is consistent with the length direction of the drying channel, and the several strip plates are fixedly arranged on the push plate. The multiple strip plates can be adjusted according to the actual air volume requirements.

[0010] Furthermore, the push plate is a main magnetic strip, and the strip plates are fixed to the push plate through the secondary magnetic blocks at their ends. The main magnetic strip and the secondary magnetic blocks attract each other magnetically. The installation and disassembly of the strip plates and the push plate are facilitated by the main magnetic strip and the secondary magnetic strip.

[0011] Furthermore, locking screws for fixing the strip plates are provided on the guide strip. The locking screws pass through the guide strip and abut against the upper surface of the strip plates. The strip plates are limited by the locking screws corresponding to each strip plate to change the length of the air outlet.

[0012] Furthermore, a rangefinder is also provided at the air outlet for detecting the distance between the paper and the air outlet. The air volume is adjusted according to the detected distance between the paper and the air outlet.

[0013] The beneficial effects of the present utility model are as follows:

[0014] The present utility model provides a paper drying device. By applying a thrust to the paper through the vertically staggered air outlets, the paper is suspended between the upper air supply group and the lower air supply group. The upper and lower sides of the paper are heated evenly, and the paper conveyed in a wavy shape has a larger heated area and a longer heating time, thereby effectively improving the drying effect of the paper.

Detailed implementation mode

[0021] The technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] In order to improve the drying effect of the paper, a paper drying device is designed. As Figure 1 and 2 shown, it includes a frame 1. The frame 1 has a paper inlet 11 and a paper outlet 12. An upper air supply group and a lower air supply group are arranged in the frame 1. A drying channel 13 connecting the paper inlet 11 and the paper outlet 12 is formed between the upper air supply group and the lower air supply group. Both the upper air supply group and the lower air supply group are composed of a number of air outlets 2. The number of air outlets 2 is arranged along the length direction of the drying channel 13. The air outlets 2 of the upper air supply group and the air outlets 2 of the lower air supply group are arranged staggeredly.

[0023] Insert the paper into the paper inlet 11, and apply upward and downward hot air forces to the paper through the staggeredly arranged upper air supply group and lower air supply group, so that the paper is suspended in the drying channel 13 between the upper air supply group and the lower air supply group. The upper and lower sides of the paper are evenly heated, and the staggeredly arranged air outlets 2 can apply a thrust to the paper, so that the paper is conveyed to the paper outlet 12 in a wavy shape, which not only increases the drying area of the paper, but also extends the drying time of the paper, thus effectively improving the drying effect of the paper.

[0024] As Figure 3 shown, a wind blocking mechanism is arranged on the air outlet 2 for adjusting the air volume. Specifically, the wind blocking mechanism includes a wind deflector 3 and a push rod 4. An extension rack 5 is arranged on one side of the air outlet 2. The wind deflector 3 moves horizontally along the extension rack 5 through the push rod 4. By adjusting the position of the wind deflector 3 through the push rod 4, the opening size of the air outlet 2 can be adjusted, that is, the air volume of the air outlet 2 can be adjusted, that is, the blowing amplitude of the wavy paper can be adjusted.

[0025] In order to guide the wind deflector 3 and ensure the horizontal movement of the wind deflector 3, a guide bar 6 is also arranged on the side of the air outlet 2 close to the extension rack 5. The guide bar 6 is provided with a strip hole through which the wind deflector 3 can pass. The wind deflector 3 passes through the strip hole and extends above the air outlet 2 to block the air outlet 2, thereby adjusting the width of the air outlet 2.

[0026] The movable end of the push rod 4 is provided with a push plate 7. The wind baffle 3 is composed of a plurality of strip plates spliced together. The length direction of the strip plates is consistent with the length direction of the drying channel 13. The plurality of strip plates are fixedly arranged on the push plate 7. The push rod 4 drives the push plate 7 to displace, and can synchronously adjust the plurality of strip plates.

[0027] The push plate 7 is the main magnetic strip. The strip plates are fixed to the push plate 7 through the secondary magnetic blocks 8 at their ends. The main magnetic strip and the secondary magnetic blocks 8 attract each other magnetically. Through the magnetic attraction of the main magnetic strip and the secondary magnetic blocks 8, the installation and disassembly of the strip plates and the push plate 7 are convenient and fast.

[0028] As Figure 4 shown, a locking screw 9 for fixing the strip plate is arranged on the guide strip 6. The locking screw 9 passes through the guide strip 6 and abuts against the upper surface of the strip plate. The strip plate can be locked individually through the locking screw 9, so that the locked strip plate will not move when the push plate 7 displaces, and the strip plates at both ends block the air outlet 2, thereby adjusting the length of the air outlet 2.

[0029] A rangefinder 10 is further arranged at the air outlet 2 for detecting the distance between the paper and the air outlet 2. When the rangefinder 10 measures that the paper is far from the air outlet 2, the push rod 4 is started to drive the wind baffle 3 to move, reducing the opening size of the air outlet 2, that is, reducing the air volume. When the rangefinder 10 measures that the paper is close to the air outlet 2, the push rod 4 is started to drive the wind baffle 3 to move, increasing the opening size of the air outlet 2, that is, increasing the air volume.

[0030] The above description is illustrative rather than restrictive to the present utility model. Those of ordinary skill in the art understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all of them will fall within the protection scope of the present utility model.
