Description

Technical Field

[0001] This utility model relates to the field of leather dewatering technology, specifically a leather dewatering machine. Background Technology

[0002] In the production of leather products, squeezing is one of the processing steps. A squeezing device is used to squeeze the leather to a semi-wet state before the next process can be carried out. A leather squeezing device, disclosed in patent CN218755819U, includes a first housing and a second housing. A connecting box is installed on the upper part of the first and second housings. A water collection tank is provided between the lower parts of the first and second housings. A linkage shaft is horizontally arranged inside the connecting box. A first motor is installed at one end of the linkage shaft to drive its rotation. First bevel gears are respectively provided at both ends of the linkage shaft. Bearings for supporting the lead screw are installed on the bottom surface of the inner cavity of the first and second housings. The top end of the lead screw penetrates the first and second housings and is provided with a second bevel gear that meshes with the first bevel gear. Connecting blocks are provided on the lead screw in both the first and second housings. A first connecting rod is provided between the two connecting blocks, and a squeezing roller is provided on the first connecting rod. An active roller is provided directly below the squeezing roller. However, in this patent document, the squeezing roller and the conveyor belt squeeze the leather. After squeezing, moisture remains on the squeezing roller and the conveyor belt. Due to the lack of a drying function, the moisture content of the leather will increase when squeezing the next piece of leather, resulting in poor squeezing effect and inconvenience.

[0003] While existing technologies may already offer solutions to the aforementioned problems, this case aims to provide an alternative or replacement technical solution. Summary of the Invention

[0020] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example: Those skilled in the art shall connect all electrical components and their compatible power supplies in this case with wires, and select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence shall refer to the working principle described below, in which the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without explaining the electrical control.

[0022] Please see Figure 1-4 In order to solve the problem that the dewatering equipment does not have a drying function, which causes the residual moisture on the dewatering equipment to increase the humidity of the leather, resulting in poor dewatering effect and inconvenience of use, this technical solution is designed. The detailed technical solution is as follows.

[0023] A leather dewatering machine includes a housing 1, a dewatering structure installed on the housing 1, a drain outlet 2 inserted into the lower side wall of the housing 1, and a drying structure installed on the housing 1 and on one side of the dewatering structure.

[0024] Specifically, the dewatering structure includes a bottom roller 3, which is movably inserted into the housing 1. A first motor 4 is installed at one end of the bottom roller 3. Two first hydraulic cylinders 23 are symmetrically inserted into the upper wall of the housing 1. A first pressure sensor 5 is installed at the telescopic end of each of the two first hydraulic cylinders 23. A connecting frame 6 is installed on the first pressure sensor 5. A lower pressure roller 7 is movably inserted into the connecting frame 6. A second motor 8 is installed at one end of the lower pressure roller 7.

[0025] It should be noted that when the leather is placed on the bottom roller 3, the two first hydraulic cylinders 23 extend, and the lower pressure roller 7 descends through the connection of the connecting frame 6. When the first pressure sensor 5 detects that the pressure value has reached the set value, the lower pressure roller 7 descends to the limit position, and the two first hydraulic cylinders 23 stop extending. Then, the first motor 4 drives the bottom roller 3 to rotate, and the second motor 8 drives the lower pressure roller 7 to rotate. The bottom roller 3 and the lower pressure roller 7 rotate in opposite directions to convey the leather and perform water squeezing. The water is discharged from the drain outlet 2. After the water squeezing is completed, the first motor 4 and the second motor 8 stop working, the two first hydraulic cylinders 23 retract, and the lower pressure roller 7 leaves the leather. The lower pressure roller 7 returns to its original position, and the operator collects the leather.

[0026] Specifically, the drying structure includes two water absorption components and a drying component;

[0027] More specifically, both water-absorbing components include two second hydraulic cylinders 9, which are installed on the inner wall of the housing 1. The telescopic ends of the two second hydraulic cylinders 9 are each equipped with a second pressure sensor 10. The second pressure sensor 10 is equipped with a mounting groove 11, and a rotating rod 12 is movably inserted into the mounting groove 11. A water-absorbing sponge sleeve 13 is fixedly fitted onto the rotating rod 12, and a third motor 14 is installed at one end of the rotating rod 12.

[0028] More specifically, the drying assembly includes a main pipe 15, which is inserted into the housing 1. A hot air blower 16 is installed at one end of the main pipe 15 outside the housing 1, and a transverse pipe 17 is installed at the other end of the main pipe 15 inside the housing 1. Multiple tee pipes 18 are installed at equal intervals on the transverse pipe 17, and two air outlets are inserted into each of the multiple tee pipes. The two air outlets correspond to the bottom roller 3 and the lower pressure roller 7, respectively.

[0029] More specifically, both air outlets include an internal drying pipe 19 and an external drying pipe 20. One end of the internal drying pipe 19 is inserted into the mounting groove 11 and is installed in correspondence with the water-absorbing sponge sleeve 13.

[0030] It should be noted that after the lower pressure roller 7 is reset, the second hydraulic cylinder 9 extends, causing the water-absorbing sponge sleeve 13 in the two water-absorbing components to adhere to the bottom roller 3 and the lower pressure roller 7. When the second pressure sensor 10 detects that the pressure value has reached the set value, the water-absorbing sponge sleeve 13 moves to the limit position, and the second hydraulic cylinder 9 stops extending. Then, the first motor 4, the second motor 8, and the third motor 14 rotate, causing the bottom roller 3, the lower pressure roller 7, the rotating rod 12, and the water-absorbing sponge sleeve 13 to rotate. The water-absorbing sponge sleeve 13 absorbs the residual moisture on the bottom roller 3 and the lower pressure roller 7. At the same time, the hot air blower 16 works, and the hot air passes through the main pipe 15, the transverse pipe 17, and the three-way pipe 18, and is discharged from the internal drying pipe 19 and the external drying pipe 20, respectively drying the bottom roller 3, the lower pressure roller 7, and the water-absorbing sponge sleeve 13, ensuring the dryness of the device, preventing the residual moisture on the device from increasing the humidity of the next piece of leather, ensuring the water-squeezing effect, and making it convenient to use.

[0031] As a preferred and further option, the main pipe 15 is a flexible and expandable structure;

[0032] As a preferred and further option, a first stabilizing bracket 21 is installed between the first motor 4 and the housing 1 for the fixed installation of the first motor 4.

[0033] Preferably, the second motor 8 is further mounted on the connecting bracket 6 for fixed installation of the second motor 8;

[0034] As a preferred and further option, a second stabilizing bracket 22 is installed between the third motor 14 and the mounting slot 11 for the fixed installation of the third motor 14.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
