Description

Technical Field

[0001] The invention relates to a rubber drying production line equipment, in particular to a rubber unloading robot for a natural rubber drying production line. Background Art

[0002] Natural rubber is a natural polymer compound with polyisoprene as the main component. The latex obtained from rubber trees is removed and diluted, then acid-coagulated, matured, creped, granulated, dried and packaged to obtain commercially available natural rubber. According to different manufacturing methods, general-purpose natural rubber can be divided into granular rubber, smoked sheet rubber, creped sheet rubber, air-dried sheet rubber and technical grade standard rubber.

[0003] my country began to introduce Hevea brasiliensis from Brazil in 1904. It has the greatest economic value and has been widely promoted. Rubber tree planting areas are mainly concentrated in Hainan and Yunnan provinces, and are also distributed in Guangdong, Guangxi and Fujian. Currently, the total planting area is about 14 million mu. By 2009, China's annual natural rubber production had reached 600,000 tons, ranking sixth in the world. At the same time, natural rubber consumption ranked first in the world.

[0004] Because natural rubber has a series of properties such as relatively good insulation, resilience, plasticity, etc., and after proper processing, it also has valuable properties such as heat resistance, acid resistance, alkali resistance, and wear resistance, so it has extremely wide applications.

[0005] Natural rubber drying is an important part of natural rubber processing. Since 2000, domestic scholars have conducted a lot of research on agricultural product drying, among which the research content on natural rubber drying is relatively rich. However, these studies are basically about the rubber drying process, and no research on the automatic production line for rubber drying has been found. The rubber truck unloading process of the rubber drying production line is currently a labor-intensive process, which relies entirely on manual operation. It not only consumes a lot of manpower, but also has great labor intensity. Therefore, the research and design of a natural rubber drying production line unloading robot can not only automate the unloading process and lay the foundation for the automation of the rubber drying production line, but also greatly save labor costs, opening up a new way for rubber companies to improve economic benefits. Therefore, the research of this project has extremely important social and economic significance. Summary of the invention

[0006] The present invention is an efficient, safe and automatic rubber drying production line rubber unloading equipment. The invention of this equipment can change the rubber unloading process of the rubber drying production line from manual operation to machine operation, which not only automates the unloading process and lays a foundation for the automation of the rubber drying production line, but also greatly saves labor costs and opens up a new way for rubber enterprises to improve economic benefits.

[0007] The technical solution adopted by the present invention to solve its technical problems is: a frame is provided, a horizontal balance beam is provided on the frame, a lifting drive mechanism is provided on the horizontal beam, a lifting motor is provided on the lifting drive mechanism, a gear transmission pair is provided at the lower end of the lifting motor, the gear transmission pair is connected to the lifting screw through a screw nut pair, a guide rod is also provided on the lifting drive mechanism, a mechanical finger transmission mechanism is provided at the lower end of the lifting screw, a mechanical finger driving motor is provided on the mechanical finger transmission mechanism, a main transmission sprocket is provided under the mechanical finger driving motor, a spiral mechanical finger is provided on the mechanical finger transmission mechanism, a transmission sprocket is provided on the upper part of the spiral mechanical finger, a guide rail is provided under the spiral mechanical finger, a glue splicing car is provided on the guide rail, the glue splicing car is provided with a glue splicing car driving motor, and a glue unloading position is also provided on one side of the frame.

[0008] Turn on the lifting motor, and drive the screw nut pair through the transmission gear pair to make the lifting screw go down, and the lifting screw drives the mechanical finger transmission mechanism to go down. When the spiral mechanical finger approaches the rubber block brought by the glue truck, start the mechanical finger drive motor, and the mechanical finger drive motor drives the transmission sprocket above the spiral mechanical finger through the main transmission sprocket and the transmission chain, and then drives the spiral mechanical finger to rotate. In this way, the spiral mechanical finger rotates while moving downward, and the spiral mechanical finger can be screwed into the rubber block brought by the glue truck. When the fingertip of the spiral mechanical finger approaches the bottom plate of the glue truck, the mechanical finger drive motor and the lifting motor stop at the same time, and then the lifting motor reverses, and drives the screw nut pair through the transmission gear pair to make the lifting screw go up, and the lifting screw passes through the mechanical finger transmission mechanism The mechanism drives the rubber block to rise. When the rubber block rises to the appropriate position, the lifting motor stops. At this time, the glue connecting car driving motor starts and drives the glue connecting car to move from the glue unloading position along the guide rail to just below the rubber block. The glue connecting car driving motor stops, and the mechanical finger driving motor reverses. The mechanical finger driving motor drives the transmission sprocket above the spiral mechanical finger through the main transmission sprocket and the transmission chain, and then drives the spiral mechanical finger to reverse. Under the action of gravity, the rubber block separates from the spiral mechanical finger and falls on the glue connecting car. Then the glue connecting car driving motor reverses and drives the glue connecting car to move from just below the spiral mechanical finger along the guide rail to the glue unloading position. The glue connecting car driving motor stops, and the glue pushing robot pushes the rubber block on the glue connecting car out of the glue connecting car. When the glue connecting car leaves just below the spiral mechanical finger, the glue car quickly transports the next group of glue to be unloaded to just below the spiral mechanical finger, and starts the lifting motor 1 at the same time to enter the next cycle.

[0009] The beneficial effect of the present invention is that the rubber unloading process of the rubber drying production line is changed from manual operation to machine operation, which not only realizes the automation of the rubber unloading process and lays a foundation for the automation of the rubber drying production line, but also greatly saves labor costs, opens up a new way for rubber enterprises to improve economic benefits, and makes the rubber unloading process of the rubber drying production line efficient, safe and automatic.
