[0024] like Figures 1 to 5 As shown, the utility model provides a drying device for hot-pressed kraft paper processing that is easy to heat evenly, comprising a drying box 1, a box door 2 and a dryer 3. The left side of the front of the drying box 1 is movably connected to the left side of the back of the box door 2 through an axle pin, and the top of the dryer 3 passes through the top of the drying box 1 and is fixedly connected to the drying box 1.

Both sides of the first clamping ring 4 are fixedly connected with connecting plates 6, and the top of the connecting plate 6 is movably connected with a screw rod 7 through an axle pin. The surface of the screw rod 7 is threadedly connected with a screw sleeve 8, and the inner side of the screw sleeve 8 is fixedly connected to both sides of the second clamping ring 5. The outer side of the connecting plate 6 is fixedly connected with a limiting sleeve 9, and the inner wall of the limiting sleeve 9 is slidably connected to the surface of the screw sleeve 8. A motor 10 is fixedly connected to the right side of the drying box 1, and the output end of the motor 10 passes through the interior of the drying box 1 and is fixedly connected to the right side of the limiting sleeve 9 away from the first clamping ring 4, and a stabilizing component 11 is fixedly connected to the left side of the limiting sleeve 9 away from the first clamping ring 4.

[0025] refer to Figure 2 The stabilizing assembly 11 includes a stabilizing rod 111, the right side of the stabilizing rod 111 is fixedly connected to the left side of the limiting sleeve 9 away from the first clamping ring 4, the left side of the stabilizing rod 111 is fixedly connected to a stabilizing plate 112, and the left side of the stabilizing plate 112 is movably connected to the left side of the inner wall of the drying box 1.

[0026] As a technical optimization scheme of the utility model, by setting a stabilizing component 11, the user can drive the stabilizing rod 111 to rotate during the flipping of the first clamp ring 4 and the second clamp ring 5, and then the stabilizing rod 111 will drive the stabilizing plate 112 to rotate, and then the left side of the stabilizing plate 112 is movably connected with the left side of the inner wall of the drying box 1, so as to ensure the stability of the left side of the first clamp ring 4 and the second clamp ring 5 when rotating, and avoid the unstable rotation of the first clamp ring 4 and the second clamp ring 5.

[0027] refer to Figure 5 The left side of the stabilizing plate 112 is fixedly connected with a rotating ring 12 , and the left side of the inner wall of the drying box 1 is provided with an annular limiting slide groove 13 , and the inner wall of the annular limiting slide groove 13 is slidably connected with the surface of the rotating ring 12 .

[0028] As a technical optimization solution of the utility model, by setting a rotating ring 12 and an annular limiting groove 13, the user can rotate the stabilizing disk 112 to drive the rotating ring 12 to rotate, and then utilize the sliding cooperation between the annular limiting groove 13 and the rotating ring 12 to make the stabilizing disk 112 movably connected to the left side of the inner wall of the drying box 1, thereby improving the stability of use.

[0029] refer to Figure 3 A rubber inner ring 14 is disposed at the top of the first clamp ring 4 and a rubber outer ring 15 is disposed at the bottom of the second clamp ring 5 .

[0030] As a technical optimization solution of the utility model, by providing a rubber inner ring 14 and a rubber outer ring 15, when the user uses the first clamp ring 4 and the second clamp ring 5 to clamp the kraft paper, the first clamp ring 4 and the second clamp ring 5 both contact the kraft paper through the rubber inner ring 14 and the rubber outer ring 15, thereby improving the friction between the first clamp ring 4 and the second clamp ring 5 and the kraft paper, thereby avoiding the kraft paper from falling off.

[0031] refer to Figure 3 The bottom of the first clamp ring 4 and the top of the second clamp ring 5 are both provided with air holes 16 , and a plurality of air holes 16 are provided and are distributed at equal distances in a rectangular shape.

[0032] As a technical optimization scheme of the utility model, through the air holes 16, which are distributed in a rectangular shape with equal distances, when the dryer 3 generates drying air, part of the drying air can enter into the gap between the rubber inner ring 14 and the rubber outer ring 15 through the air holes 16, thereby drying the clamping part of the kraft paper and improving the drying effect.

[0033] refer to Figure 4The top of the screw rod 7 is fixedly connected to the force application disk 17, and the rubber inner ring 14 and the rubber outer ring 15 are fixedly connected to the first clamping ring 4 and the second clamping ring 5 through PET glue.

[0034] As a technical optimization scheme of the utility model, by setting a force disk 17, when the user needs to rotate the screw 7, the user can directly drive the screw 7 to rotate by rotating the force disk 17, which provides the user with a fulcrum for applying force. By utilizing the advantage of good heat resistance of PET glue, the fixing effect of the first clamp ring 4 and the second clamp ring 5 is improved, and the first clamp ring 4 and the second clamp ring 5 are prevented from falling off due to excessive stability.

[0036] As a technical optimization solution of the utility model, by providing an anti-skid groove 18, when the user holds the force application disk 17 and rotates it, the user's hand can contact the force application disk 17 through the anti-skid groove 18, thereby increasing the friction between the user's hand and the force application disk 17, preventing slipping due to excessively low friction, and improving the stability when rotating the force application disk 17.

[0037] The working principle and use process of the utility model are as follows: when the user needs to dry the kraft paper, the user can lay the kraft paper flat between the first clamping ring 4 and the second clamping ring 5, and then the user can rotate the screw 7, and then the screw 7 will drive the screw sleeve 8 to move downward, so that the screw sleeve 8 drives the second clamping ring 5 to clamp the kraft paper, so as to position the kraft paper, and then the user can start the dryer 3 to dry the kraft paper, and in the process of drying the kraft paper, the user can also start the motor 10, so that the motor 10 drives the first clamping ring 4 and the second clamping ring 5 The first clamp ring 4 and the second clamp ring 5 rotate to continuously flip the kraft paper, thereby ensuring that both sides of the kraft paper are evenly dried and improving the drying efficiency. During the flipping process of the first clamp ring 4 and the second clamp ring 5, the stabilizing rod 111 is also driven to rotate, and then the stabilizing rod 111 drives the stabilizing plate 112 to rotate. Then, the left side of the stabilizing plate 112 is movably connected to the left side of the inner wall of the drying box 1, thereby ensuring the stability of the left side when the first clamp ring 4 and the second clamp ring 5 rotate, avoiding the unstable rotation of the first clamp ring 4 and the second clamp ring 5, and having the ability of auxiliary positioning.

[0038] In summary, the drying device for hot-pressed kraft paper processing that facilitates uniform heating, by setting a first clamping ring 4 and a second clamping ring 5, uses the first clamping ring 4 and the second clamping ring 5 to clamp and position the kraft paper, and then the user can start the dryer 3 to dry the kraft paper, and can also start the motor 10 to drive the kraft paper to continuously flip, thereby ensuring that both sides of the kraft paper are evenly dried, thereby solving the problem of lack of a mechanism for positioning the kraft paper in the dryer, resulting in the kraft paper being affected by the airflow during the drying process, causing the kraft paper to constantly shake, and during the drying process of the kraft paper, the bottom of the kraft paper is blocked, thereby affecting the drying effect of the bottom of the kraft paper.
