Description

Technical Field

[0001] The utility model generally relates to the field of leather drying, and in particular to a leather drying device. Background Art

[0002] European patent EP3705585A3 discloses a drying machine for flexible laminar elements, preferably animal skins, comprising a drying channel in which a partition wall defines a first drying chamber provided with an air inlet duct and a second drying chamber provided with an exhaust hood, and a collecting pipe connects the air inlet duct to the exhaust hood.

[0019] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant utility model, rather than to limit the utility model. It is also necessary to explain that, for ease of description, only the parts related to the utility model are shown in the accompanying drawings.

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0021] Please refer to Figures 1 to 5The leather drying device of the utility model comprises: a conveyor belt 100, which comprises a conveying part 110 and a rotating part 120, wherein the conveying part 110 is located above the rotating part 120; a drying tunnel 200, which is used to generate dry hot air; an upper air outlet mechanism 300, which comprises an upper air duct 310 and a plurality of upper air outlets 320, wherein the upper air duct 310 is connected to the drying tunnel 200, and the plurality of upper air outlets 320 are arranged on the upper air duct 310; The lower air outlet mechanism 400 includes a lower air duct 410 and a plurality of lower air outlets 420, wherein the plurality of lower air outlets 420 are arranged on the lower air duct 410, and the lower air duct 410 is located between the conveying part 110 and the rotating part 120; and an air induced duct 500, one end of which is connected to the upper air duct 310, and the other end of which is connected to the lower air duct 410, and the conveying part 110 supports the leather and drives the leather to pass through between the upper air outlet 320 and the lower air outlet 420.

[0022] In the embodiment of the present utility model, the conveyor belt 100 includes a conveying portion 110 and a rotating portion 120 , and the conveying portion 110 is used to support the leather and drive the leather to move.

[0023] The drying tunnel 200 generates dry hot air. The upper air duct 310 is connected to the drying tunnel 200, and the upper air duct 310 is provided with a plurality of upper air outlets 320, and the dry hot air is blown out through the upper air outlets 320. The lower air duct 410 is connected to the upper air duct 310 through the induced air duct 500, and the dry hot air enters the lower air duct 410 through the induced air duct 500, and the lower air duct 410 is provided with a plurality of lower air outlets 420, and the dry hot air is blown out from the lower air outlets 420.

[0024] The conveying part 110 drives the leather to pass between the upper air outlet 320 and the lower air outlet 420. The dry hot air blown out of the upper air outlet 320 and the dry hot air blown out of the lower air outlet 420 can simultaneously dry the leather on the conveying part 110, thereby effectively reducing the moisture content of the leather. This prevents the leather with high moisture content from being burned when the leather subsequently enters the RF drying tunnel 200 for drying, thereby ensuring product quality.

[0025] Furthermore, an arc-shaped first air induction portion 510 is provided at one end of the air induction duct 500, and the first air induction portion 510 is detachably fixedly connected to the upper air duct 310.

[0026] An arc-shaped second air induction portion 520 is disposed at one end of the air induction duct 500 , and the second air induction portion 520 is detachably fixedly connected to the lower air duct 410 .

[0027] In the embodiment of the utility model, when the drying hot air passes through the first air induction part 510 and the second air induction part 520 from the upper air duct 310 through the air induction duct 500 and enters the lower air duct 410, the flow direction will be changed. By arranging the first air induction part 510 and the second air induction part 520 into an arc shape, the drying hot air is facilitated to flow in the air induction duct 500.

[0028] The first air induction part 510 is detachably fixedly connected to the upper air duct 310, and the second air induction part 520 is detachably fixedly connected to the lower air duct 410, so that the air induction duct 500 can be easily installed. When the leather drying device fails, the air induction duct 500 can be disassembled to observe the conditions of the upper air duct 310 and the lower air duct 410 and perform maintenance, which reduces the difficulty of maintenance.

[0029] Furthermore, a plurality of through holes are arranged in an array on the conveyor belt 100 .

[0030] In the embodiment of the utility model, a plurality of through holes (not shown in the figure) are arranged in an array on the conveyor belt 100, and water can drip from the through holes when the conveyor portion 110 supports the leather. In addition, when the lower air outlet 420 blows air toward the conveyor portion 110, the dry hot air can pass through the through holes and directly blow to the lower surface of the leather, thereby ensuring the efficiency of drying the leather.

[0031] refer to Figure 2 and 4 Furthermore, two induced air ducts 500 are provided, one end of the downwind duct 410 is connected to one induced air duct 500 , and the other end of the downwind duct 410 is connected to the other induced air duct 500 .

[0032] In an embodiment of the utility model, two induced air ducts 500 are provided, and the two induced air ducts 500 are located on both sides of the downwind duct 410. The two induced air ducts 500 can allow more dry hot air to enter the downwind duct 410, and the two induced air ducts 500 can play a role in lifting the downwind duct 410.

[0033] Furthermore, a gap of 5 to 6 cm is provided between the air duct 500 and the conveyor belt 100 .

[0034] In the embodiment of the utility model, when the conveying part 110 supports the leather and drives the leather to move, the conveyor belt 100 may deviate. By setting a gap of 5 to 6 cm between the induced air duct 500 and the conveyor belt 100, interference between the induced air duct 500 and the conveyor belt 100 is avoided.

[0035] refer to Figure 5 Furthermore, the lower air outlet 420 is provided with an air inlet portion 421 and an air outlet portion 422 , and a cross-sectional area of ​​the air inlet portion 421 is greater than a cross-sectional area of ​​the air outlet portion 422 .

[0036] In an embodiment of the present utility model, the dry hot air first enters the lower air outlet 420 through the air inlet 421, and then flows out of the lower air inlet from the air outlet 422. The cross-sectional area of ​​the air inlet 421 is larger than the cross-sectional area of ​​the air outlet 422, so that the dry hot air has a faster flow rate when flowing out of the lower air inlet from the air outlet 422.

[0037] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model. For example, the above features are replaced with the technical features with similar functions disclosed in the present application (but not limited to) by each other to form a technical solution.
