Description

Technical Field

[0001] The present application relates to the technical field of leather manufacturing equipment, and in particular to a leather drying machine. Background Art

[0002] Leather is an animal skin that has been modified and not easily rotten after physical and chemical processing such as depilation and tanning. It is widely used in clothing, furniture, and car interiors. In the leather making process, it is generally necessary to use evaporation drying after wet processing to convert the water or solvent in the leather into steam, and then drive away the steam to reduce the moisture content of the leather.

[0003] There is a leather dryer in the prior art, which includes a drying rack and a heat exchanger. The number of drying racks is set to be several, and a heating chamber is opened in each drying rack, and a water inlet pipe and a water outlet pipe are provided on each drying rack. One end of each water inlet pipe and water outlet pipe is connected to the heating chamber in the corresponding drying rack, and the other end is connected to the heat exchanger. The heat exchanger is used to heat the liquid in its own chamber and then pass it into each water inlet pipe. A closed cover is provided on the top of each drying rack, and the leather is placed in the chamber between the closed cover and the corresponding drying rack. When in use, the heat exchanger passes the heated liquid into the heating chamber in each drying rack through the water inlet pipe, so that the top wall of the drying rack is heated by heat exchange, and then the closed cover is opened, and the leather is placed on the top wall of the drying rack, and then the closed cover is covered. After that, the drying rack heats the leather by heat transfer, so that the moisture or solvent in the leather is heated and becomes steam, thereby drying the leather.

[0004] With regard to the above-mentioned related technologies, since the closed cover on the corresponding drying rack needs to be opened in the process of placing the leather on the top wall of the drying rack one by one, after the closed cover is opened, the heat transfer effect between the corresponding drying rack and the outside world will be aggravated, which may easily lead to a change in the water circulation state between the heat exchanger and the drying rack, and then easily cause the temperature of the liquid in the water inlet pipe of the heat exchanger to drop, resulting in a decrease in the temperature in the chamber between the remaining drying racks and the corresponding closed cover, which reduces the overall drying efficiency of the leather, so it needs to be improved.

[0052] Reference Figure 4 , Figure 6 and Figure 7 Each conveying mechanism 8 further includes a leveling frame 86 and a moving assembly 87. Both ends of each leveling frame 86 along its length direction are slidably connected to the extension portion 821 on the corresponding conveying frame 82, and the sliding direction is the vertical direction. A leveling roller 88 is provided at the bottom end of each leveling frame 86. The axial direction of each leveling roller 88 is the width direction of the machine body 1. Each leveling roller 88 is rotatably connected to the corresponding leveling frame 86 through a bearing.

[0053] Reference Figure 4 , Figure 6 and Figure 7 The bottom end of each leveling roller 88 is lower than the bottom end of the leveling frame 86, so that the bottom end of the leveling roller 88 can be easily abutted against the leather surface on the corresponding drying frame 3, thereby reducing the friction force on the leather surface through rolling friction and ensuring the quality of the leather after drying.

[0054] Reference Figure 6 and Figure 7 , each conveying mechanism 8 has two movable components 87, which are respectively arranged at the two ends of the leveling frame 86 along its own length direction, and are arranged one by one with the clamping frame 841. Each movable component 87 includes a rotating frame 871, a sleeve frame 872 and a linkage member 873, and the middle part of each rotating frame 871 is rotatably connected to the corresponding conveying frame 82 through a pin. Both ends of each rotating frame 871 are arranged to be inclined upward in a direction away from each other.

The length of one end of each rotating frame 871 close to the leveling frame 86 is greater than the length of the other end thereof, so as to increase the amount of sliding of the leveling frame 86 when the rotating frame 871 rotates.

[0056] Reference Figure 4 , Figure 6 and Figure 7 In the initial state, the conveying frame 82 is located at the end of its sliding path closest to the corresponding conveyor belt 85, and the leveling roller 88 is located directly above the conveyor belt 85. At this time, the clamping frame 841 is close to the conveyor belt 85, and the bottom end does not contact the conveying frame 82. When the corresponding drying frame 3 moves downward to separate the drying frame 3 from the corresponding sealing cover 5, the corresponding watering assembly 7 sprays water onto the corresponding drying frame 3.

[0057] Reference Figure 4 , Figure 6 and Figure 7 After that, the conveyor belt 85 transports one end of the leather to be dried to between the clamping rack 841 and the conveying rack 82. At this time, the clamping rack 841 moves downward under the drive of the sliding member 842, thereby clamping the leather together with the conveying rack 82. After that, the conveying component 83 drives the conveying rack 82 to gradually move away from the conveyor belt 85, and makes the conveying rack 82 located directly above the corresponding drying rack 3.

[0058] Reference Figure 4 , Figure 6 and Figure 7 When the leather is completely on the drying rack 3, the sliding member 842 drives the clamping rack 841 to move upward, thereby canceling the clamping of the leather. At this time, the leveling roller 88 is located at the end of the leather close to the conveyor belt 85. In this process, the clamping rack 841 drives the linkage rack 8731 to move upward, so that the linkage rack 8731 drives the rotating rack 871 to rotate, and then the end of the rotating rack 871 away from the linkage rack 8731 rotates downward.

[0059] Reference Figure 4 , Figure 6 and Figure 7At this time, the rotating frame 871 drives the corresponding leveling frame 86 to move downward through the sleeve frame 872, so that the leveling roller 88 gradually moves downward and finally the leather surfaces are against each other. In this process, the sleeve frame 872 and the linkage member 873 both slide relative to the rotating frame 871 to adapt to the rotation of the rotating frame 871. Thereafter, the conveying assembly 83 continues to drive the conveying frame 82 to slide, so that the leveling roller 88 level the leather. After the leveling is completed, the sliding member 842 drives the clamping frame 841 to move upward again, and the conveying assembly 83 drives the conveying frame 82 to move back to the initial position.

[0060] The implementation principle of a leather dryer in Example 2 of the present application is as follows: when the corresponding drying rack 3 moves downward to separate the drying rack 3 from the corresponding sealing cover 5, the corresponding watering assembly 7 sprays water onto the corresponding drying rack 3. Thereafter, the conveyor belt 85 conveys the leather to be dried, and the clamping assembly 84 clamps the leather. After the clamping is completed, the conveying assembly 83 drives the conveying rack 82 to slide, so that the leather is completely located on the drying rack 3.

[0061] After that, the sliding member 842 drives the clamping frame 841 to move upward, thereby canceling the clamping of the leather. During this process, the clamping frame 841 drives the corresponding leveling frame 86 to move downward through the moving assembly 87, so that the leveling roller 88 finally contacts the surface of the leather. After that, the conveying assembly 83 continues to drive the conveying frame 82 to slide, so that the leveling roller 88 can level the leather. After the leveling is completed, the sliding member 842 drives the clamping frame 841 to move upward again, and the conveying assembly 83 drives the conveying frame 82 to move back to the initial position. After that, the lifting assembly 4 drives the drying frame 3 to move upward and contacts the corresponding sealing cover 5, so that the drying frame 3 can dry the leather.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
