Technical Field

[0001] This utility model relates to the technical field of burr removal devices, and in particular to a burr removal device for rubber diaphragms. Background Technology

[0002] Rubber diaphragms, as thin film sheets made of natural or synthetic rubber, are widely used in many industrial fields due to their excellent flexibility, resilience, insulation, water resistance, and plasticity. They are mainly used to manufacture various seals, shock absorbers, waterproof materials, medical gloves, etc., and are indispensable materials, especially in the automotive, electronics, medical device, and packaging industries.

[0003] During the molding process of rubber diaphragms, burrs easily form on their sidewalls. These burrs not only affect the appearance quality of the product but may also adversely impact its sealing performance, wear resistance, and other properties. Therefore, effectively removing burrs from rubber diaphragms is a crucial step in improving product quality and production efficiency. Currently, burr removal from rubber diaphragms mainly relies on manual operation, which is inefficient and difficult to meet the needs of large-scale production. Utility Model Content

[0022] Example:

[0023] Please see Figures 1-4 This utility model provides a technical solution: a rubber diaphragm burr removal device, including a support platform 1, an auxiliary frame 2 fixedly connected to the upper end of the support platform 1, a burr cutting mechanism provided on the auxiliary frame 2, a bottom support plate 19 provided below the burr cutting mechanism, a limit post 21 fixedly connected to the upper end of the bottom support plate 19, a support rod 22 fixedly connected to the lower end of the bottom support plate 19, and a cleaning mechanism provided on the outside of the burr cutting mechanism;

[0024] The rough edge cutting mechanism includes an electric push rod 3, which is fixed to the upper end of the auxiliary frame 2. The output end of the electric push rod 3 passes through the auxiliary frame 2 and is fixedly connected to a lifting plate 4. A clamping ring 11 is provided below the lifting plate 4, and a cutting blade 8 is fixedly connected to the outer side of the lifting plate 4. The cutting blade 8 is annular, and a bottom support plate 19 is adapted to the annular cutting blade 8. In use, several rubber diaphragms 20 are placed on the bottom support plate 19, and the position of the rubber diaphragms 20 is limited by the limiting post 21. The electric push rod 3 pushes the annular cutting blade 8 and the clamping ring 11 to move downward. The contact pad 12 at the lower end of the clamping ring 11 contacts the upper end of the rubber diaphragm 20. The clamping ring 11 and the bottom support plate 19 cooperate to fix the position of the rubber diaphragm 20. The electric push rod 3 continues to push the cutting blade 8 and the lifting plate 4 downward and compress the buffer spring 15. As the cutting blade 8 continues to move downward, the precise automatic cutting of the product rough edges is achieved.

[0025] The cleaning mechanism includes a blower 5 and a cleaning cylinder 7. The output end of the blower 5 is fixedly connected to an air pipe 6. The upper end of the cutter 8 passes through the upper side wall of the cleaning cylinder 7 and is fixedly connected to the cleaning cylinder 7. The end of the air pipe 6 away from the blower 5 passes through the upper side wall of the cleaning cylinder 7 and is connected to the cleaning cylinder 7. A diverter plate 9 is provided between the cleaning cylinder 7 and the cutter 8. The diverter plate 9 is annular. The outer end of the diverter plate 9 is fixedly connected to the inner side wall of the cleaning cylinder 7. Several ventilation holes 10 are provided on the diverter plate 9. The air blown out by the blower 5 through the air pipe 6 is diverted by the diverter plate 9 and the ventilation holes 10, thereby ensuring that the burrs at the lower end of the cutter 8 are cleaned.

[0026] A sliding rod 14 is fixedly connected to the upper end of the clamping ring 11. The upper end of the sliding rod 14 passes through the lifting plate 4 and is fixedly connected to the baffle 13. The sliding rod 14 is slidably connected to the lifting plate 4. A buffer spring 15 is sleeved on the sliding rod 14. The upper and lower ends of the buffer spring 15 are fixedly connected to the adjacent side walls of the lifting plate 4 and the clamping ring 11, respectively. The design of the buffer spring 15 effectively absorbs the impact force during the cutting process and protects the equipment and the rubber diaphragm 20 from damage.

[0027] A contact pad 12 is fixedly connected to the lower end of the clamping ring 11. The contact pad 12 is made of rubber material. The contact pad 12 is designed to prevent the clamping ring 11 from directly contacting the rubber diaphragm 20 and causing damage to the rubber diaphragm 20.

[0028] A collection mechanism is provided above the support platform 1. The collection mechanism includes a collection box 16, which is fixed to the upper end of the support platform 1. The support rod 22 is fixed to the lower inner wall of the collection box 16. The upper end of the collection box 16 is open. A rubber sheet 17 is provided at the upper port of the collection box 16. A collection port 18 is opened on the rubber sheet 17. The bottom support plate 19 is located inside the collection port 18. During the burr cutting process, the lower ends of the cutting blade 8 and the cleaning tube 7 pass through the collection port 18 and extend to the bottom support plate 19 and the rubber sheet 17. Under the action of the blower 5 and the air pipe 6, the cut burrs are blown into the collection box 16 for collection, which is convenient for subsequent processing and recycling.

[0029] Working principle: In use, several rubber diaphragms 20 are placed on the bottom support plate 19, and the position of the rubber diaphragms 20 is limited by the limiting post 21. The electric push rod 3 pushes the annular cutting knife 8 and the pressing ring 11 to move downward. The contact pad 12 at the lower end of the pressing ring 11 contacts the upper end of the rubber diaphragm 20. The pressing ring 11 and the bottom support plate 19 cooperate to fix the position of the rubber diaphragm 20. The electric push rod 3 continues to push the cutting knife 8 and the lifting plate 4 to move downward and compress the buffer spring 15. As the cutting knife 8 continues to move downward, the product burrs are accurately and automatically cut, thereby ensuring product quality and product processing efficiency. During the burr cutting process, the lower ends of the cutting knife 8 and the cleaning tube 7 pass through the collection port 18 and extend to the bottom support plate 19 and below the rubber sheet 17. Under the action of the blower 5 and the air pipe 6, the cut burrs are blown into the collection box 16 for collection, which is convenient for subsequent processing and recycling.
