A pressing mechanism 300 for fixing the leather is arranged above the drying plates 200. The pressing mechanism 300 includes a fixing frame 310. Sliding grooves 311 are respectively opened on the side walls of the left and right sides of the fixing frame 310. A flattening and pressing assembly 320 is arranged between the two sliding grooves 311. The flattening and pressing assembly 320 includes rollers 321 that are rollingly arranged in each sliding groove 311. A connecting shaft 322 is arranged between the rollers 321 in the two sliding grooves 311. A flattening roller 323 is arranged on the outer side of the connecting shaft 322. The present utility model can realize the flattening and pressing operation of the leather placed on the drying plates 200 through the flattening and pressing assembly 320, avoiding the insufficient drying caused by the wrinkling of the leather when the operator places the leather, and even seriously causing the wrinkling and deformation of the dried leather, affecting the drying efficiency and quality of the leather, and solving the problem that the traditional dryer 100 only places the leather on the drying plates 200 when drying leather, relying on manual smoothing of the wrinkles, resulting in poor smoothing effect, low efficiency, and being prone to the situation that all wrinkles cannot be completely smoothed due to the operator's mistakes, ultimately reducing the drying efficiency and drying quality of the dryer 100 for leather.
[0023] According to an embodiment of the present utility model, as Figures 1-4 shown, there are four rollers 321, and two rollers 321 are rollingly arranged in each sliding groove 311. A connecting shaft 322 is respectively arranged between the two rollers 321 in two different sliding grooves 311 located on the same horizontal straight line. The present utility model can fix and connect the two rollers 321 through the connecting shaft 322, and can drive the connecting shaft 322 thereon and the flattening roller 323 on the connecting shaft 322 to roll together through the rolling action of the rollers 321 in the sliding grooves 311, thereby realizing the flattening and pressing treatment of the leather in the fixing frame 310 during the rolling process of the flattening roller 323, and cooperating with the drying function of the dryer 100 to realize the efficient and stable drying operation of the leather, and the operation is more convenient and efficient.
[0024] According to another embodiment of the present utility model, as Figure 1 , Figure 2and Figure 4 As shown, on the upper parts of the left and right sides of the fixed frame 310, guiding grooves 312 communicating with the sliding grooves 311 are respectively formed.

[0027] The using method of the present utility model:
[0028] First of all, it should be clear that the dryer 100 involved in the present utility model is mainly used for the drying operation of fabrics or leather products. Taking the drying of leather as an example, the usage method of the present utility model will be elaborated in detail. When it is necessary to perform a drying operation on leather, first place the leather to be dried into the sliding grooves 311 of the fixed frame 310 in sequence. Then, first align the two rollers 321 with the flattening rollers 323 and slide them into the two sliding grooves 311. Then, the operator pushes the exhibit roller to roll in the sliding groove 311. Under the action of the external force and the rotation of the rollers 321, the flattening roller 323 will flatten the leather laid in the fixed frame 310. Then, the operator pushes the hand-tightening bolts 333 on the left and right sides with both hands and pushes them inward along the guiding groove 312 until they reach a suitable position relative to the two rollers 321 pushed into the sliding groove 311. Then, the operator grabs the other two rollers 321 with the flattening rollers 323 and repeats the above flattening work. After the flattening is completed, the operator first turns the pair of hand-tightening bolts 333 near the inside clockwise until the bolts drive the retaining plates 334 to move downward to a height where the position of the inner rollers 321 is limited and blocked. Then, the operator grabs the other two hand-tightening bolts 333 with both hands and turns them until a height where the position of the outer rollers 321 can be limited and blocked is achieved. Then, the operator pulls outward until the two outer rollers 321 are pushed to a position about 3 mm away from the other end of the leather. Then, the operator turns the four hand-tightening bolts 333 clockwise in sequence until the bottoms of the retaining plates 334 below the hand-tightening bolts 333 come into contact with the leather and then turns them one more turn downward. Thus, the flattening and pressing fixation of the leather to be dried are achieved. Repeat the above actions to perform the flattening and pressing fixation operations on the leather in each fixed frame 310. After the operation, the operator closes the sealing door of the drying box 103 and then starts the blower 102 for the drying operation. The present utility model can realize the flattening and pressing fixation operation on the leather placed on the drying plate 200 through the flattening and pressing assembly 320, avoiding the problem that when the operator places the leather, the leather has wrinkles, resulting in insufficient drying. Seriously, it may even cause the dried leather to have wrinkled deformation, affecting the drying efficiency and quality of the leather, and solving the problem that the traditional dryer 100 only places the leather on the drying plate 200 when drying leather, relying on manual smoothing of the wrinkles, which has a poor smoothing effect, low efficiency, and is prone to incomplete smoothing of all wrinkles due to the operator's mistakes, ultimately reducing the drying efficiency and drying quality of the dryer 100 for leather.

For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0030] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
