The inner wall of the heating box is fixedly installed with a heating plate, the inner wall of the heating box is fixedly installed with a hanging rod, the middle part of the upper surface of the movable plate is fixedly installed with a base, the inner part of the base is movably connected with a driven wheel, and the top of the driven wheel is fixedly connected with a turntable. During use, the leather stretch board drying device starts the second servo motor to rotate the threaded rod, which can drive the movable plate to move and move on the bare rod, so that the leather can be sent into the heating box, and the hydraulic telescopic rod is started to adjust the height of the support frame, and the hanging ring can be hung on the hanging rod for drying. After drying, the leather stretch board can be used after a round trip process operation to avoid burns, thereby making the leather stretch board drying device not only easy to use, but also safe to operate and high in drying efficiency.

[0004] It was found during use that the above patent easily generates water vapor when the leather is placed in the heating box for heating. The patent lacks a drainage assembly, and the water vapor evaporated from the leather easily gathers at the top of the heating box and condenses into water droplets and continues to flow back, causing the leather to regain moisture and affecting its drying effect. For this reason, we proposed a leather stretcher drying device to solve the above problem. Utility Model Content

A leather stretch board drying device comprises: a drying box 1, a box door 2 and an air outlet 3, a heating plate 4 is installed inside the drying box 1, a blower fan 5 is fixedly installed on the side of the drying box 1, an air outlet of the blower fan 5 is connected to a receiving air chamber 6, a bottom of the receiving air chamber 6 is connected to a pressure equalizing air chamber 7, a plurality of air outlets 8 are densely arranged on the pressure equalizing air chamber 7, a stretch board 9 is arranged on the upper side of the pressure equalizing air chamber 7, leather 15 is laid on the stretch board 9, an operating handle is arranged on the box door 2, a flip cover is rotatably installed on the air outlet 3, a rotating shaft 10 is fixedly installed on the rear side of the stretch board 9, the rotating shaft 10 rotates and passes through the rear side of the drying box 1 and a toothed disc 12 is fixedly installed on the rear side end of the rotating shaft 10, a motor 13 is fixedly installed on the rear side wall of the drying box 1, a gear 14 is fixedly installed on the output end of the motor 13, the gear 14 is meshed with the toothed disc 12, and a clamp 16 is arranged on the stretch board 9.

[0025] In this embodiment, the clamp 16 includes a double-headed threaded column 161, both ends of which are provided with threads, and through holes 91 are evenly distributed on the tension plate 9. The double-headed threaded column 161 is inserted into the inner side of the through hole 91 and threaded covers 162 are screwed and installed at both ends of the double-headed threaded column 161.

[0026] Through the arrangement in the above manner, when the leather 15 is placed on the stretching board 9, the double-headed threaded column 161 is inserted into the through hole 91 at its edge, and the threaded covers 162 on the upper and lower sides are tightened so that the bottom of the threaded cover 162 presses the leather 15 onto the stretching board 9. By fixing the four corners of the leather 15 with clamps 16, the entire leather 15 is clamped and fixed on the stretching board 9. When the stretching board 9 rotates, the leather 15 can rotate with it without falling off.

[0027] In this embodiment, a protective sleeve 11 is provided at the rotation connection between the rotating shaft 10 and the drying box 1 . The protective sleeve 11 is fixedly connected to the rear side wall of the drying box 1 , and the rotating shaft 10 rotates through the protective sleeve 11 .

[0028] By the above-mentioned arrangement, the setting of the casing 11 makes the rotation connection of the rotating shaft 10 more stable.

[0029] In this embodiment, a compression washer 163 is fixedly installed at the bottom of the threaded cover 162 , and the outer diameter of the compression washer 163 is larger than that of the threaded cover 162 .

[0030] By the arrangement in the above manner, the outer expansion area of ​​the clamping washer 163 is larger than that of the threaded cover 162. When the threaded cover 162 is rotated and pressed down, the clamping washer 163 can be pressed on the upper side of the leather 15, thereby increasing the clamping area and making the leather 15 more securely clamped and fixed.

[0031] In this embodiment, the air outlet tube 8 includes a cone 81 , a communicating air hole 82 is provided at the bottom of the cone 81 , the communicating air hole 82 is connected to the inside of the pressure equalizing air chamber 7 , and a gradually expanding opening 83 is connected to the upper side of the communicating air hole 82 .

[0032] By the above-mentioned arrangement, the diameter of the connecting air hole 82 is relatively small, and a certain air pressure is generated inside the pressure-equalizing air chamber 7 under the continuous action of the blowing fan 5. Under the action of the air pressure, the air enters the gradually expanding opening 83 through the connecting air hole 82, generating a uniform airflow flowing upward.

[0033] The working principle of a leather stretch board drying device provided by the utility model is as follows:

[0034] When in use, the leather 15 is stretched and placed on the stretching plate 9, double-headed threaded columns 161 are placed on the sides of the four corners of the leather 15, and the double-headed threaded columns 161 are inserted into the through holes 91 at the edges thereof, and the threaded covers 162 on the upper and lower sides are tightened so that the compression washers at the bottom of the threaded covers 162 press the leather 15 on the stretching plate 9, and the box door 2 is closed, and the motor 13, the heating plate 4 and the blowing fan 5 are started. Under the action of the heating plate 4, the temperature inside the drying box 1 rises, and the leather 15 is dried. At the same time, under the drive of the motor 13, the leather fixed on the stretching plate 9 rotates with the stretching plate 9, so that the leather 15 is dried. The heat is more uniform. Under the action of the blowing fan 5, the blowing fan 5 sends air into the receiving air chamber 6, and the receiving air chamber 6 sends the air into the equalizing air chamber 7. The air outlet pipes 8 evenly distributed on the upper side of the equalizing air chamber 7 produce an effect of uniform upward blowing, so that a uniform upward airflow is formed at the bottom of the drying box 1. When the airflow flows upward, it drives the water vapor at the evaporation point of the leather 15 to the top of the drying box 1 and is discharged from the air outlet pipe 3, so that the water vapor evaporated from the drying box 1 is quickly discharged, avoiding the leather 15 from regaining moisture due to the reflux of water vapor in the drying box 1, thereby improving the drying efficiency of the leather 15 and enhancing the practicality.

[0035] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
