Description

Technical Field

[0001] This invention relates to film production equipment, and in particular to a fully automatic film cutting device. Background Technology

[0002] The production of rubber products typically involves the forming of rubber sheets, which involves cutting the refined rubber sheets into specific shapes. The existing cutting process involves manually transporting the refined square rubber sheets to the extended platform of the cutting machine, manually placing the die to be formed onto the square rubber sheet, pushing the extended platform into the cutting machine, pressing the cutting button to complete one cutting task, manually pulling the cutting platform out, manually removing the waste material, and transferring the formed rubber sheet to a weighing platform for weighing and recording the weight. During this process, the workers in front must wait for this step to complete. The weighed and qualified rubber sheets are manually transferred to pre-prepared pallets. After each layer of rubber sheets is placed, a layer of insulating cloth is laid down to prevent the sheets from sticking together. Finally, the qualified rubber sheets are transferred by forklift to the assembly workbench for assembly. This process requires a large number of operators and poses a risk of workplace injuries. Therefore, a fully automated rubber sheet cutting device is needed to solve these problems.

[0003] Chinese invention patent CN215881825U discloses a rubber stopper punching and feeding device. The feeding of this invention is carried out sequentially at a single station, which is inefficient. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problems, thereby providing a fully automatic film punching and cutting device to increase film production output.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows:

[0006] A fully automatic film punching device includes a punching mechanism and a weighing mechanism. The punching mechanism is located in the middle of a punching conveyor line. Waste glue separation mechanisms and punching stations for feeding film to the punching mechanism are respectively provided at both ends of the punching conveyor line. A first transfer platform and a second transfer platform are symmetrically arranged on the front and rear sides of the punching conveyor line. A semi-finished product conveyor belt is arranged on the outer side of the first transfer platform. A first gripping conveyor line is arranged between the middle of the first transfer platform and the semi-finished product conveyor belt, and the first gripping conveyor line is equipped with a first gripping mechanism. A second gripping conveyor line and a third gripping conveyor line are symmetrically arranged between the two ends of the two transfer platforms. Both the second and third gripping conveyor lines are equipped with a second gripping mechanism and a third gripping mechanism.

The bottom surface of the outer end of the connecting plate 19-5 is equipped with a pressure column 19-6.

[0053] The working process of this embodiment is as follows: The square film 20 is transported by the semi-finished product conveyor belt 1 to the first gripping mechanism 4 directly below the first gripping conveyor line 3. The suction cup 4-1 of the first gripping mechanism 4 picks up the film 20 and moves it to the first station 2-4-1 of the transfer platform plate 2-4 of the first transfer platform 2, and then puts the film 20 down. The first station 2-4-1 of the transfer platform plate 2-4 moves to the lower part of the second gripping conveyor line 9. The second gripping mechanism 11 moves to the upper part of the film 20, picks up the film 20 and transports it to the pressure plate 6-9 of the left support frame 6-1 of the punching conveyor line 6. At this time, the third gripping mechanism 12 is located above the second transfer platform 7.

[0054] The first servo motor 6-5 and drive belt 6-6 drive the pressure plate 6-9 and film 20 into the punching mechanism 5. The hydraulic cylinder 5-5 of the punching mechanism 5 drives the punching platform 5-2 to press down the film 20, punching and cutting the film 20. At the same time, the punching platform 5-2 is equipped with a material ejection mechanism to knock the inner waste rubber 20-3 of the film 20 onto the waste rubber conveyor line 18 below. Simultaneously, the second gripping mechanism 11 moves to the top of the first transfer platform 2, and the third gripping mechanism 12 moves to the top of the left support frame 6-1 to wait. After punching is completed, the pressure plate 6-9 and film 20 return to their original positions and move below the third gripping mechanism 12. The piston rod of the upper separation cylinder 19-2 of the waste rubber separation mechanism 19 extends, and the piston rod of the lower separation cylinder 19-4 drives the pressure column 19-6 to move down and press down the cut waste rubber 20-2. The third gripping mechanism... Mechanism 12 picks up the molded film 20-1 and conveys it to the first station 2-4-1 of the transfer platform plate 2-4 of the second transfer platform 7. The transfer platform plate 2-4 of the second transfer platform 7 transports the molded film 20-1 directly below the fourth gripping mechanism 15 of the fourth gripping conveyor line 13. The fourth gripping mechanism 15 conveys the molded film 20-1 to the finished product conveyor belt 8. The molded film 20-1 is transported forward on the finished product conveyor belt 8 and passes through the automatic weighing mechanism 17. As the molded film 20-1 passes by, the weighing mechanism 17 weighs the molded film 20-1. Films with a weight within the preset weight range are gripped by the robot and transferred to the next assembly process 16. Films with an unqualified weight continue to move forward along the finished product conveyor belt 8 and fall into the waste glue collection box 14 at the end of the finished product conveyor belt 8, waiting to be reused. After the waste glue 20-2 is picked up by the second gripping mechanism 11 or the third gripping mechanism 12, it enters the punching mechanism 5 at the first station 2-4-1 of the transfer platform plate 2-4, and the waste glue 20-2 falls into the gap of the left support frame 6-1 and onto the waste glue conveying line 18.

[0055] The above process describes the entire operation of the second gripping conveyor line 9 at one side of the workstation. The third gripping conveyor line 10, located symmetrically, performs corresponding actions intermittently during the intervals between these actions. When the first workstation 2-4-1 of the transfer platform plate 2-4 of the first transfer platform 2 moves to below the second gripping mechanism 11 of the second gripping conveyor line 9, the first gripping mechanism 4 picks up the next sheet of film 20 from the semi-finished product conveyor belt 1 and transports it to the second workstation 2-4-2 of the transfer platform plate 2-4 of the first transfer platform 2. After the second gripping mechanism 11 of the second gripping conveyor line 9 picks up the previous sheet of film 20, the second workstation 2-4-2 of the transfer platform plate 2-4 moves to below the second gripping mechanism 11 of the third gripping conveyor line 10. The second gripping mechanism 11 then transports the next sheet of film 20 to the pressure plate 6-9 of the right support frame 6-2. At this time, the pressure plate 6-9 of the left support frame 6-1 is at the punching machine. Inside structure 5, as the upper film 20 of the pressure plate 6-9 of the left support frame 6-1 is punched out of the punching mechanism 5, the pressure plate 6-9 of the right support frame 6-2 and the next film 20 enter the punching mechanism 5 for punching. After punching, the third gripping mechanism 12 of the third gripping conveyor line 10 picks up the formed film 20-1 and transports it to the second station 2-4-2 of the transfer platform plate 2-4 of the second transfer platform 7. The second station 2-4-2 of the transfer platform plate 2-4 moves to directly below the fourth gripping mechanism 15 of the fourth gripping conveyor line 13. The fourth gripping mechanism 15 transports the formed film 20-1 to the finished product conveyor line 16. The subsequent operation process is the same as that of the second gripping conveyor line 9 and the finished product conveyor belt 8.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. All equivalent structural changes made based on the description and drawings of the present invention are included within the scope of the present invention.
