[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-6 As shown, a sheet feeding device includes a base 1, an mounting frame 2 is fixedly connected to the upper side of the base 1 near the left and right sides, a drying box 3 is fixedly connected to the middle of the mounting frame 2 near the upper side, a bottom barrel 4 is movably installed on the lower side of the drying box 3, a control mechanism 5 is movably installed on the front side of the drying box 3, and a stirring mechanism 6 is fixedly connected to the inner side of the bottom barrel 4 near the upper side.

[0028] The stirring mechanism 6 includes a first support frame 61. The outer side of the first support frame 61 is fixedly connected to the inner side of the bottom tank 4 near the upper side. A first quick-release assembly 62 is fixedly connected to the upper middle part of the first support frame 61. A motor 63 is fixedly connected to the upper side of the first quick-release assembly 62. A stirring frame 64 is fixedly connected to the output end of the motor 63. A second quick-release assembly 65 is movably sleeved on the outer side of the stirring frame 64 near the upper side. A second support frame 66 is rotatably connected to the outer side of the second quick-release assembly 65. The outer side of the second support frame 66 is fixedly connected to the inner side of the drying oven 3 near the upper side.

[0029] It should be noted that the drying chamber 3 has the same flow pipes and components as in the reference case. The pipe used for ash removal is equipped with a filter screen to prevent sheet material from entering. The bottom barrel 4 and the drying chamber 3 are connected by a quick-release buckle to facilitate the removal of the bottom barrel 4. The first quick-release assembly 62 is used to quickly install the motor 63 on the first support frame 61, and the second quick-release assembly 65 is used to quickly install the upper side of the stirring rack 64 on the second support frame 66 to stabilize the upper side of the stirring rack 64.

[0030] like Figure 4As shown, the first quick-release assembly 62 includes a base plate 621. The upper side of the base plate 621 is fixedly connected to the lower side of the motor 63. A retaining sleeve 622 is movably sleeved on the outer side of the base plate 621. The lower side of the retaining sleeve 622 is fixedly connected to the upper middle part of the first support frame 61. Several annularly distributed balls 623 are movably sleeved on the inner side of the side wall of the retaining sleeve 622. The outer side of the balls 623 is movably sleeved in a groove opened on the outer side of the base plate 621. A limiting sleeve 624 is rotatably connected to the outer side of the retaining sleeve 622. Several annularly distributed ball grooves 625 are opened on the inner side of the limiting sleeve 624.

[0031] It should be noted that a torsion spring is provided between the limiting sleeve 624 and the first support frame 61. In the initial state, the ball groove 625 and the ball 623 are arranged alternately, so that the ball groove 625 restricts the ball 623, causing the ball 623 to fix the base plate 621. When the limiting sleeve 624 is rotated, so that the ball groove 625 is aligned with the ball 623, the ball 623 does not fix the base plate 621.

[0032] like Figure 4 As shown, a number of annularly distributed limiting grooves 626 are provided on the lower side of the limiting sleeve 624 near the inner side, and the protrusion on the outer side of the sleeve 622 near the bottom is movably sleeved on the inner side of the limiting groove 626.

[0033] It should be noted that the limiting groove 626 is used to limit the rotation range of the limiting sleeve 624, so that the limiting sleeve 624 can directly rotate the ball groove 625 to the position aligned with the ball 623.

[0034] like Figure 4 As shown, a number of ring-shaped retaining strips 627 are fixedly connected to the outer side of the base plate 621, and the outer side of the retaining strips 627 is movably sleeved in the vertical groove opened on the inner side of the retaining sleeve 622.

[0035] It should be noted that the retaining strip 627 is used to restrict the base plate 621 so that the outer retaining groove of the base plate 621 can be aligned with the ball bearing 623 when the retaining sleeve 622 is inserted.

[0036] like Figure 5 As shown, the second quick-release assembly 65 includes a first transmission rod 651. The outer side of the first transmission rod 651 is rotatably connected to the inner side of the second support frame 66. A circular plate 652 is fixedly connected to the outer side of the first transmission rod 651 near the lower side. Several annularly distributed limiting rods 653 are fixedly connected to the lower side of the circular plate 652 near the edge. A transmission sleeve 654 is movably sleeved on the outer side of the limiting rods 653. The inner side of the transmission sleeve 654 is movably sleeved on the outer side of the first transmission rod 651 near the lower side and the outer side of the stirring rack 64 near the upper side.

[0037] It should be noted that the lower side of the transmission sleeve 654 is flared, so that the outer side of the stirring frame 64 near the upper side can be directly inserted into the inner side of the transmission sleeve 654. The transmission sleeve 654 is used to synchronize the first transmission rod 651 and the stirring frame 64, so that when the stirring frame 64 rotates, it drives the first transmission rod 651 to rotate.

[0038] like Figure 5 As shown, springs 655 are movably sleeved on the outer side of several limiting rods 653, and the springs 655 are located on the upper side of the transmission sleeve 654.

[0039] It should be noted that the spring 655 is used to push the transmission sleeve 654 to prevent the transmission sleeve 654 from being directly and rigidly fixed to the lower side of the circular plate 652, which would cause rigid collisions between the parts when installing the mixing rack 64, or allow it to move on its own to the lower side of the circular plate 652, thus ensuring the stability of the moving parts of the transmission sleeve 654.

[0040] like Figure 3 As shown, a second transmission rod 67 is rotatably connected to the lower side of the second support frame 66 near the left side. Both ends of the second transmission rod 67 and the outer side of the first transmission rod 651 near the upper side are fixedly connected to bevel gears 68. The two bevel gears 68 on the right side are meshed together. A gear ring 69 is rotatably connected to the lower side of the second support frame 66 near the edge. The left side of the gear ring 69 is meshed with the lower side of the left bevel gear 68. Several ring-shaped brushes 610 are fixedly connected to the lower side of the gear ring 69.

[0041] It should be noted that when the first transmission rod 651 rotates, it drives the bevel gear 68 on the first transmission rod 651 to rotate. The second transmission rod 67 makes the bevel gear 68 on the left rotate synchronously. When the bevel gear 68 rotates, it drives the gear ring 69 to rotate, which in turn makes the gear ring 69 drive the brush 610 to revolve. At the same time, the indirect transmission of the bevel gear 68 and the gear ring 69 to the brush 610 is used to reduce the revolve speed of the brush 610.

[0042] The working principle of this utility model is as follows: First, a torsion spring is provided between the limiting sleeve 624 and the first support frame 61. In the initial state, the ball groove 625 and the ball 623 are alternately arranged, so that the ball groove 625 restricts the ball 623, causing the ball 623 to fix the bottom plate 621. When the limiting sleeve 624 is rotated, so that the ball groove 625 is aligned with the ball 623, the ball 623 is not fixed to the bottom plate 621. The lower side of the transmission sleeve 654 is flared, so that the outer side of the stirring frame 64 near the upper side can be directly inserted into the inner side of the transmission sleeve 654. The transmission sleeve 654 is used to synchronize the first transmission rod 651 and the stirring frame 64, so that when the stirring frame 64 rotates, it drives the first transmission rod 651 to rotate. When the bottom barrel 4 and the drying box 3 are separated, the direct sleeve action of the transmission sleeve 654 drives the stirring frame 64 directly to the second support. The frame 66 is separated, and then the limiting sleeve 624 is rotated, so that the motor 63 can be quickly separated from the bottom barrel 4, causing the components to be quickly separated into several parts, reducing maintenance costs. Finally, when the first transmission rod 651 rotates, it drives the bevel gear 68 on the first transmission rod 651 to rotate. Relying on the second transmission rod 67, the bevel gear 68 on the left side rotates synchronously. When the bevel gear 68 rotates, it drives the gear ring 69 to rotate, which in turn drives the brush 610 to revolve. At the same time, the indirect transmission of the bevel gear 68 and the gear ring 69 to the brush 610 is used to reduce the revolve speed of the brush 610. The motor 63 drives the brush 610 to revolve, which in turn makes the brush 610 clean the inside front of the drying box 3, so that the filter screen on the pipe used for dust removal on the drying box 3 is cleaned, and the sheet is prevented from being adsorbed on the filter screen, which would lead to poor air circulation.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
