Description

Technical Field

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

[0002] Flame-retardant coated paper is made by adding flame retardants and other special processes to traditional coated paper. Compared with ordinary coated paper, flame-retardant coated paper has a significantly slower burning speed when exposed to a fire source, and the spread of flames is also suppressed, thus reducing the risk of fire. In the production of coated paper, excess moisture needs to be removed from the paper through a dryer to ensure that the paper reaches the expected degree of dryness. When drying coated paper, hot air is often used, but traditional hot air drying does not have the function of blowing air from both the top and bottom simultaneously, which can easily lead to uneven heating of the paper and a longer drying time, reducing production efficiency. Utility Model Content

[0024] 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.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a production dryer, comprising: a support base 1; a second fixed bracket 7 fixedly connected to the top of the support base 1; an adjusting support plate 4 placed above the support base 1, with a first fixed bracket 5 fixedly connected to the bottom of the adjusting support plate 4, and ventilation boxes 8 fixedly connected to the bottom of the first fixed bracket 5 and the top of the second fixed bracket 7; a ventilation net 9 fixedly connected to the inside of the ventilation box 8, with a material inlet 26 symmetrically opened on the top of one of the ventilation boxes 8; a connecting air box 12 fixedly connected to one side of the ventilation box 8, the connecting air box 12 communicating with the ventilation box 8, a fixed air box 13 fixedly connected to one side of the connecting air box 12, the fixed air box 13 and the connecting air box 12 connected by an air duct, and multiple electric heating wires 16 arranged inside the fixed air box 13; a top support frame 17 symmetrically fixedly connected to the top of the support base 1, with a guide roller 18 rotatably arranged on the inner side of the top support frame 17; and a limiting slip ring 19 symmetrically slidably arranged on the outer side of the guide roller 18.

[0026] Understandably, this utility model guides the flame-retardant coated paper to be dried using guide roller 18, adjusts the sliding ring 19 on the outer side of guide roller 18, and adjusts the distance between the two sliding rings 19. After adjusting the appropriate distance, the tightening bolt 23 is rotated, and the tightening bolt 23 tightens the limiting slide groove 21, thus fixing the adjusted position of the fixed side block 22 and the limiting slip ring 19. The guide roller 18 and the limiting slip ring 19 guide the conveying position of the flame-retardant coated paper, which enters the ventilation box 8 through the feed port 26. The output end of the cylinder 3 drives the adjusting support plate 4, the first fixed bracket 5, and the other ventilation box 8 to move downwards, and the limiting plate 10 enters the limiting groove 11, thus fixing the two slides. The positions of the air boxes 8 are merged, and the flame-retardant coated paper moves inside the ventilation box 8. The output end of the external fan is connected to the air inlet pipe 24. The fan draws air into the air distribution box 14 through the air inlet pipe 24. The airflow is filtered by the filter screen 15 inside the air distribution box 14. After filtration, the airflow enters the two fixed air boxes 13 through the air duct. The airflow in the fixed air box 13 enters the connecting air box 12 and enters the ventilation box 8 through the air duct. The airflow is discharged through the ventilation net 9 inside the ventilation box 8. The hot air is discharged through the ventilation net 9 and dries the flame-retardant coated paper conveyed in the ventilation box 8. After drying, the hot air is discharged through the feed port 26. Excess moisture on the flame-retardant coated paper will be discharged through the drain pipe 25 in one of the ventilation boxes 8.

[0027] Please see Figures 1 to 5 It also includes a support frame 2, which is fixedly connected to the top of the support base 1. A cylinder 3 is installed on the top of the support frame 2. The output end of the cylinder 3 is fixedly connected to the adjusting support plate 4. Multiple limiting slide rods 6 are symmetrically fixedly connected to the top of the adjusting support plate 4. The limiting slide rods 6 are slidably connected to the support frame 2.

[0028] It is understood that this utility model adjusts the position of the adjusting support plate 4, the first fixed bracket 5 and the bottom ventilation box 8 through the output end of the cylinder 3, and merges the two ventilation boxes 8 to perform hot air drying treatment on the coated paper inside the two ventilation boxes 8.

[0029] Please see Figures 1 to 5 A distribution box 14 is provided on one side of the support base 1. The fixed air box 13 and the distribution box 14 are connected by an air duct. An air inlet pipe 24 is fixedly connected to one side of the distribution box 14. A filter screen 15 is installed inside the distribution box 14 by bolts.

[0030] It is understood that the air inlet pipe 24 of this utility model blows air into the air distribution box 14 through an external fan, and filters impurities in the airflow through the filter screen 15.

[0031] Please see Figures 1 to 5Multiple limiting sliders 20 are fixedly connected at equal intervals on the inner side of the guide roller 18, and multiple limiting grooves 21 that cooperate with the limiting sliders 20 are opened at equal intervals on the outer side of the guide roller 18. The limiting sliders 20 and the limiting grooves 21 are slidably connected.

[0032] It is understood that the limiting slip ring 19 of this utility model is limited and slidably adjusted on the outside of the guide roller 18. The limiting slip ring 19 drives the limiting slider 20 and the limiting groove 21 to slide in a limited manner, thereby improving the stability of the adjustment of the limiting slip ring 19.

[0033] Please see Figures 1 to 5 A fixed side block 22 is symmetrically fixed to one side of the limiting slip ring 19. The fixed side block 22 is internally threaded with a tightening bolt 23 that mates with the limiting slip groove 21. A drain pipe 25 is fixed to one side of one of the ventilation boxes 8.

[0034] It is understood that one end of the tightening bolt 23 of this utility model is tightened and fixed to the limiting slide groove 21. After the tightening bolt 23 tightens the limiting slide groove 21, the adjustment position of the fixed side block 22 and the limiting slide ring 19 on the outside of the guide roller 18 can be limited and fixed.

[0035] Please see Figures 1 to 4 One of the ventilation boxes 8 has a symmetrically provided limiting groove 11 on its top, and the other ventilation box 8 has a symmetrically fixed limiting plate 10 that cooperates with the limiting groove 11 on its bottom.

[0036] It is understood that when the two ventilation boxes 8 of this utility model are merged, the limiting plate 10 and the limiting groove 11 cooperate to position and merge the two ventilation boxes 8.
