[0033] The utility model provides a drying device for dry puffed paper production, comprising a workbench 1, a drying box 2 is provided on the top of the workbench 1, a plurality of extrusion assemblies 3 are provided on one side of the drying box 2, the extrusion assemblies 3 include a first support frame 31, the first support frame 31 is installed on the workbench 1, and an upper extrusion cylinder 32 and a lower extrusion cylinder 33 are installed in the first support frame 31.
[0034] By clamping the puffed paper between the upper extrusion cylinder 32 and the lower extrusion cylinder 33, the excess water can be squeezed out under the action of pulling and clamping. Because there are multiple extrusion cylinders, it can be squeezed and drained multiple times. In addition, the drying box 2 set at one end is used for drying. By clamping it in the middle and squeezing it relatively, it is more efficient than squeezing only one side and can be dried quickly. In addition, there is a device for pulling and moving the puffed paper outside, which belongs to the prior art and will not be described here.

The puffed paper is clamped and squeezed by the inclined extrusion block 34, and then an air outlet 35 communicated with the extrusion cylinder is set on the inclined extrusion block 34, and the blowing rod 36 set inside the cylinder is rotated to blow air, and then the puffed paper is blown, which can speed up the drying speed of the puffed paper and reduce the moisture to a certain extent. In addition, the inclined extrusion block 34 is tilted outward toward the front end, so that it is squeezed along the tilted direction of the inclined extrusion block 34 when moving, so as to avoid the inclined extrusion block 34 blocking the puffed paper and causing it to wrinkle.
[0036] According to some embodiments of the utility model, optionally, a squeezing strip 37 is provided on one side of the opposite side of the upper squeezing cylinder 32 and the lower squeezing cylinder 33, and the end face of the squeezing strip 37 is an arc-shaped surface. The squeezing strip 37 can first squeeze out moisture from the puffed paper, and then squeeze and dry it through the inclined squeezing block 34, which can accelerate the loss of moisture and improve the overall drying efficiency. In addition, the squeezing portion of the opposite side of the squeezing strip 37 and the inclined squeezing block 34 is an arc-shaped surface, so that the puffed paper will not be damaged during squeezing.
[0037] According to some embodiments of the utility model, optionally, the first support frame 31 is provided with a second support frame 4 at the front end, and a constant temperature block 41 is provided on the second support frame 4. A chute 42 for the puffed paper to pass through is provided in the constant temperature block 41, and heating blocks 43 are provided in the upper and lower sides of the chute 42. A constant temperature block 41 is provided in the direction of pulling the puffed paper forward, so that the puffed paper passes through the chute 42 of the constant temperature block 42, and then a certain temperature is set by the heating block 43, which can also speed up the drying speed of the puffed paper.
[0038] According to some embodiments of the utility model, optionally, the heating block 43 is arranged in a groove 44, the groove 44 is arranged in the slide slot 42, and a spring 45 is arranged between the heating block 43 and the groove 44. In order to allow the heating block 43 to contract through the spring 45 when passing through the puffed paper, it is convenient to pass through the puffed paper.
[0039] According to some embodiments of the present invention, the upper extrusion cylinder 32 and the lower extrusion cylinder 33 are optionally slidably connected to the first support frame 31. In this way, the two extrusion cylinders can be moved up and down to facilitate passing through the expanded paper. The sliding connection method can be fixed at a certain place, which belongs to the prior art and will not be described again.
[0040] According to some embodiments of the present invention, optionally, a collecting box 11 is provided in the middle of the workbench 1 at the bottom of the first supporting frame 31 to collect the squeezed water.
[0041] According to some embodiments of the utility model, optionally, a plurality of drying fans 21 are provided in the upper and lower sides of the drying box 2. Drying at the upper and lower sides can quickly dry the clothes. The drying fan 21 has the same principle as the hair dryer, and will not be described again.
