Description

Technical Field

[0001] The invention relates to the technical field of leather drying, in particular to a leather drying machine. Background Art

[0002] Leather is usually dried using a leather vacuum dryer. The main drying step is to place the leather product to be dried in a drying room, and then use a vacuum pump to evacuate the air inside the drying room to create a vacuum environment and extract some moisture. The heating device then raises the room temperature to evaporate the moisture inside the leather product. At the same time, the evaporation rate of water vapor in a vacuum environment increases, which is conducive to the rapid discharge of moisture from the leather product.

[0003] When leather first enters a vacuum environment, it contains more moisture, so it takes more time and energy to evaporate the moisture. Because leather products contain more moisture, the vacuum pump takes longer to create an ideal vacuum environment, resulting in slow leather drying efficiency. The moisture in the leather will evaporate rapidly under vacuum and heating conditions, and the generated steam will have an impact on the leather. If the leather product is not pre-dried, the moisture content inside it will be higher and the impact will be greater, which can easily damage the quality of the leather. Summary of the invention

[0036] like Figure 5 As shown, the middle portion of the guide groove 2650 is an arc segment, and the upper and lower portions of the guide groove 2650 are vertical segments.

[0037] like Figure 1 , Figure 2 and Figure 3As shown, the driving member 266 includes a telescopic cylinder 2660, and the upper end surface of the upper module 21 is installed with the telescopic cylinder 2660, and the telescopic end of the telescopic cylinder 2660 is installed with a connecting plate 2661, and the connecting plate 2661 is provided with a No. 2 waist groove at the position corresponding to the shaft rod 263 one by one, and the upper end of the shaft rod 263 slides through the corresponding No. 2 waist groove, and the upper and lower end surfaces of the connecting plate 2661 are slidably installed with baffles 2662 at the position corresponding to the No. 2 waist groove, and the two upper and lower opposite baffles 2662 are coaxially fixedly connected with the corresponding shaft rod 263.

[0038] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the adsorption component 268 includes a fixing plate 2680, and the lower end surface of the shaft 263 is installed with a fixing plate 2680, and the lower end surface of the fixing plate 2680 and the side away from the corresponding shaft 263 are rotatably installed with a T-shaped column 2681, and the two T-shaped columns 2681 opposite to each other on the left and right are jointly provided with a suction cup 2682, and the upper end surface of the suction cup 2682 is provided with a T-shaped groove, and the two T-shaped columns 2681 opposite to each other on the left and right are slidably installed in the corresponding T-shaped grooves, and the front and rear ends of the T-shaped groove are installed with blocking blocks 2683 for limiting the movement of the T-shaped column 2681.

[0039] like Figure 1 and Figure 2 As shown, the push-pull member 267 includes a connecting plate 2670, and a connecting plate 2670 is installed between two left and right opposite sliding plates 261, and the opposite surfaces of the two connecting plates 2670 are provided with rectangular plates 2671 slidably installed on the upper module 21, and the opposite ends of the two rectangular plates 2671 are symmetrically installed with guide rods 2672 that slide through the corresponding connecting plates 2670, and a compression spring 2673 is installed between the rectangular plates 2671 and the corresponding connecting plates 2670, and a two-way cylinder 2674 is installed on the upper end surface of the upper module 21, and the two telescopic sections of the two-way cylinder 2674 are respectively fixedly connected to the corresponding rectangular plates 2671.

[0040] During specific operation, the external conveying mechanism moves the leather to be dried after cleaning to the right side of the lower module 22, and then the horizontal section of the cross slide 20 drives the upper module 21 to move to the top of the leather to be dried, and then the telescopic cylinder 2660 pulls the connecting plate 2661 to move downward, and the connecting plate 2661 drives the shaft 263 to move downward, and the shaft 263 cooperates with the upper vertical section of the guide groove 2650 through the guide column 2651 to keep the fixed plate 2680 moving vertically downward, and then the fixed plate 2680 and the suction cup 2680 move downward. 2651 moves to the lower part of the vertical section of the upper module 21. At this time, the guide column 2651 moves to the arc section of the guide groove 2650. As the shaft 263 moves downward, the guide column 2651 slides in the arc section of the guide groove 2650, so that the shaft 263 rotates 90 degrees, that is, the fixing plate 2680 changes from the horizontal state to the vertical state. The fixing plate 2680 drives the corresponding T-shaped column 2681 to slide in the corresponding T-shaped groove to push the corresponding suction cup 2682 to move to the upper part of the leather to be dried. At the same time, the T-shaped column 2681 and the suction cup 2682 are pressed together. The corresponding blocking block 2683 interferes to limit the movement of the suction cup 2682, thereby improving the stability of the suction cup 2682. At this time, the guide column 2651 moves to the lower vertical section of the guide groove 2650, and then the telescopic cylinder 2660 continues to push the shaft 263 downward through the connecting plate 2661. Through the cooperation of the guide column 2651 and the lower vertical section of the guide groove 2650, the suction cup 2682 is vertically downward to fit the leather, and then the external negative pressure adsorption device causes the suction cup 2682 to adsorb the leather, and then the cross slide The vertical section of 20 drives the upper module 21 and the sucked leather to move upward, and then drives the upper module 21 and the sucked leather to move horizontally to just above the lower module 22 through the horizontal section of the cross slide 20, and then the two-way cylinder 2674 pushes the corresponding two rectangular plates 2671 away from each other, and the rectangular plate 2671 drives the corresponding slide plate 261 to move through the compression spring 2673 and the connecting plate 2670, and the slide plate 261 pulls the leather through the shaft 263, the fixing plate 2680 and the suction cup 2682 to tension the leather.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the rolling part 27 includes a support plate 270, and the left and right end surfaces of the upper module 21 are slidably installed with the support plate 270 through an electric slider, and the support plate 270 is an L-shaped structure, and a waist plate 271 is rotatably installed on the lower part of the vertical end of the support plate 270 through an axis column, and two rollers 272 are commonly installed on the opposite surfaces of the two waist plates 271, and one of the support plates 270 is provided with an adjusting member 273 for driving the waist plate 271 to rotate.

[0042] like Figure 1 and Figure 6As shown, the adjusting member 273 includes a servo motor 2730, the shaft column rotates through the support plate 270, and the shaft column is coaxial with one of the roller shafts 272. The servo motor 2730 is installed on the support plate 270 through a motor seat, and the output shaft of the servo motor 2730 is connected to the shaft column through a bevel gear set 2731.

[0043] like Figure 7 As shown, heating pipes 12 are installed inside the upper module 21 and inside the lower module 22 .

[0044] During specific operation, the servo motor 2730 drives the shaft column to rotate, and the shaft column drives the waist plate 271 to rotate, and the waist plate 271 drives the roller 272 which is not coaxial with the shaft column to be tangent to the lower end surface of the leather, and then the electric slider drives the support plate 270 to move horizontally, and the movement of the support plate 270 drives the roller 272 to roll the leather to squeeze out part of the moisture on the leather. Since the leather is adsorbed and fixed on the top of the lower module 22 by the suction cup 2682, the water squeezed out of the lower end surface of the leather will fall by its own gravity, while the moisture on the upper end surface of the leather does not directly drip by gravity, but the roller 272 can squeeze the moisture on the upper end of the leather from the leather fibers and form droplets on the upper end of the leather. With the continuous movement and further squeezing of the roller 272, part of the droplets will The other part of the droplets are re-absorbed into the leather due to the decrease in the saturation of water discharged from the lower end of the leather, and are then squeezed out by the roller 272 again. The roller 272 rolls the leather back and forth for many times to ensure the effect of the pre-drying treatment of the leather, thereby improving the efficiency of leather drying. When the roller 272 coaxial with the shaft column moves to the middle of the leather, the servo motor 2730 drives the shaft column to rotate, so that the roller 272 not coaxial with the shaft column rotates to be tangent to the lower end surface of the leather on the other side of the support plate 270, thereby ensuring the squeezing of the leather part under the suction cup 2682 on the other side, and the support plate 270 is driven to move back and forth left and right and the roller 272 is rotated by the electric slider to ensure the pre-drying effect of the leather.

[0045] Then the support plate 270 moves to the end of the leather, and then the servo motor 2730 drives the shaft column to rotate, so that the roller shaft 272 that is not coaxial with the shaft column rotates to a position tangent to the upper end surface of the leather, and then the vertical section of the cross slide 20 drives the upper module 21 and the sucked leather to move downward until the leather is fitted with the lower module 22, and then the telescopic cylinder 2660 pushes the connecting plate 2661 to move upward, and the connecting plate 2661 drives the shaft rod 263 to move, and the shaft rod 263, with the cooperation of the guide column 2651 and the guide groove 2650, moves the suction cup 2682 upward away from the leather, and then drives the suction cup 2682 to move to the bottom of the horizontal section of the upper module 21 through the rotation of the shaft rod 263 and the fixed plate 2680, and then moves the suction cup 2682 to between the horizontal section and the vertical section of the upper module 21 with the movement of the shaft rod 263 and the fixed plate 2680. Then, the electric slider drives the support plate 270 and the roller 272 to move to the horizontal section position of the upper module 21, so as to avoid interfering with the downward movement of the upper module 21, and then the vertical section of the cross slide 20 drives the upper module 21 to squeeze the leather, and at the same time, the sealing ring 25 contacts the upper end surface of the vertical section of the lower module 22, and then the external negative pressure vacuum device is connected to the pipeline 24, and the air between the upper module 21 and the lower module 22 is evacuated through the pipeline 24 and the circular hole 23, and at the same time, part of the moisture on the leather is extracted, and at the same time, the heating tube 12 is energized to release heat to dry the leather. The evaporation rate of water vapor in the vacuum environment increases, which is beneficial to accelerate the discharge of moisture in the leather products; after the vacuum drying of the leather is completed, the upper module 21 moves away from the lower module 22, and then the dried leather is taken out, and then the above operation is repeated to continue the leather material collection and drying process.
