Technical Field

[0001] The utility model belongs to the technical field of cowhide preparation, and particularly relates to a cowhide conveying and automatic unloading device. Background Art

[0002] In the leather processing industry, the conveying and unloading of cowhide is a crucial process. Traditional methods of conveying and unloading cowhide mostly rely on manual labor or simple mechanical devices, which is not only inefficient but also prone to high labor intensity and operational risks for workers. With the continuous advancement of science and technology, the application of automation technology in the leather processing field is becoming more and more extensive. Among them, the automatic cowhide conveying and unloading device is one of the important technological innovations.

[0003] Currently, there are some automatic leather conveying and unloading devices on the market that have been produced or put into use. Most of them use the flexible movement of a robotic arm to grab and unload the leather. However, this device has intermittent operation during the unloading process, that is, it can only process one piece of leather at a time, and the position of the unloading mechanism cannot be adjusted according to the position or size of the leather, which to a certain extent limits its scope of use and efficiency.

[0004] In order to overcome the above-mentioned deficiencies in the prior art, it is necessary to propose a new type of automatic leather unloading device for conveying and unloading cowhide. Utility Model Content

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0022] like Figure 1-5 As shown, a cowhide conveying and automatic unloading device comprises a conveyor belt 1, a placing platform 2 is fixed obliquely below one side of the conveyor belt 1, and a plurality of rotating columns 17 are connected to the top of the placing platform 2 for uniform rotation. Through the setting of the rotating columns 17, the cowhide is transported to the placing platform 2 on the conveyor belt 1, and falls onto the placing platform 2, and slides in the direction away from the conveyor belt 1 through the rotating columns 17 until the whole cowhide is smoothly transferred to the placing platform 2, so as to avoid the cowhide from being stacked. The outer surface of the rotating column 17 is a smooth surface setting. Through this setting, The cowhide can slide more smoothly on the rotating column 17. A mounting column 3 is provided on the top of the placement table 2. The bottom of the mounting column 3 is rotatably connected to a rotating plate 5. A motor 4 is installed on the inner side of the mounting column 3, and the output end of the motor 4 is fixedly connected to the center position of the mounting column 3. When the motor 4 is used for driving, it drives the rotating plate 5 to rotate, and the motor 4 can stop after rotating to a certain angle, such as when it rotates to a certain hydraulic cylinder 6 described below and is aligned with the cowhide on the placement table 2. The mounting column 3 can be installed on the ceiling or other equipment;

[0023] Three hydraulic cylinders 6 are provided at the bottom of the rotating plate 5. An assembly structure is installed at the output end of the hydraulic cylinder 6. A fan 7 corresponding to the hydraulic cylinder 6 is provided on the side of the rotating plate 5. A plurality of air guide hoses 8 are installed at the input end of the fan 7. A suction cup 9 is installed at the end of each air guide hose 8 away from the fan 7. The assembly structure is used to assemble multiple suction cups 9. The side of the suction cup 9 is provided with multiple embossed prints. Through this arrangement, the suction cup 9 can press down when in contact with the cowhide to further increase the suction force between the cowhide and the suction cup 9.

[0024] When unloading the cowhide, after the cowhide is transported to the placement table 2, the fan 7 is started, so that the fan 7 generates negative pressure in the suction cup 9 through the air guide hose 8, and the hydraulic cylinder 6 is started, so that the hydraulic cylinder 6 drives multiple suction cups 9 to move downward until they come into contact with the cowhide, and the cowhide is sucked by the negative pressure generated by the suction cup 9 until the cowhide is attached to the suction cup 9, and the motor 4 is started, so that the output end of the motor 4 drives the rotating plate 5 to rotate, and drives the hydraulic cylinder 6 and the suction cup 9 to rotate, and the hydraulic cylinder 6 on the placement table 2 rotates to the top of the collection basket, the fan 7 stops starting, the negative pressure at the suction cup 9 disappears, and the cowhide falls into the collection basket. At this time, another hydraulic cylinder 6 rotates to the top of the placement table 2, sucks the next piece of cowhide, and moves it, thereby completing the automatic unloading of the cowhide.

[0025] Refer to the attached Figure 4 The assembly structure includes a connecting frame 15 fixed to the bottom of the stroke rod of the hydraulic cylinder 6, and a bottom support plate 16 is fixed to the bottom of the connecting frame 15, and a fixing block 10 is fixed on the top of the bottom support plate 16 and located inside the connecting frame 15. A cavity is provided on the inner side of the connecting frame 15, and the fixing block 10 can be arranged in the cavity. A first push rod motor 11 is installed at both ends of the fixing block 10, and a sliding plate 12 is fixed to the end of the stroke rods of the two first push rod motors 11 away from each other. Both ends of the top of the bottom support plate 16 are provided with grooves for guiding the sliding plate 12. Through this arrangement, the sliding plate 12 can slide in the groove and provide supporting force for the first push rod motor 11 to avoid a large supporting force on the first push rod motor 11. A second push rod motor 13 is fixed on both sides of the sliding plate 12, and a fixing plate 14 is fixed to the end of the two second push rod motors 13 away from each other, and the suction cup 9 is installed at the bottom end of the fixing plate 14;

[0026] When it is necessary to change the position of the suction cup 9 according to the position or size of the cowhide, the first push rod motor 11 can be started to make the positions of the suction cups 9 at both ends move away from or closer to each other. When the second push rod motor 13 is started, the positions of the two suction cups 9 at the same end can be changed to move away from or closer to each other, so that the position of the suction cup 9 can be more adapted to the position or size of the cowhide.

[0027] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
