[0002] Rubber is an organic flammable material that is a safety hazard. Therefore, rubber conveyor belts used in mines and various rubber accessories for vehicles and ships are required to have flame retardant and flame retardant properties. Flame retardant rubbers include: chloroprene rubber, chlorosulfonated polyethylene, polyvinyl chloride and silicone rubber. The flame retardancy can be improved by using flame retardant polymers with flammable rubber, such as polyvinyl chloride and nitrile rubber. Increasing the cross-linking density of vulcanized rubber can also improve flame resistance. Flame retardant rubber accessories are widely used in various aspects of industry or life. During the production and processing process, the rubber needs to be stretched according to actual needs.

[0034] See also Figure 1 The frame assembly 1 includes a frame 11, a first support plate 12, a first vertical arm 13 and a cantilever 14. The first support plate 12 is fixedly arranged at the upper end of the frame 11. The first vertical arm 13 is vertically fixedly arranged at the right end of the first support plate 12. The cantilever 14 is located directly above the first support plate 12. The cantilever 14 is perpendicular to and fixedly connected to the first vertical arm 13.

[0035] The frame 11 is used to support the first support plate 12 , and the cantilever 14 is installed on the first vertical arm 13 to form an L-shaped support arm, which is convenient for the subsequent installation of the stretching component 2 .

[0036] See also Figure 1The stretching assembly 2 includes a first cylinder 21, an upper mold 22 and a lower mold 23. The first cylinder 21 is vertically fixed on the cantilever 14, and the output end of the first cylinder 21 extends downward from the cantilever 14. The upper mold 22 is fixed at the output end of the first cylinder 21. The lower mold 23 is fixed on the first support plate 12 and is located directly below the upper mold 22.

[0037] By turning on the first cylinder 21, the first cylinder 21 drives the upper mold 22 to move downward, and the upper mold 22 presses the rubber on the lower mold 23 to form a rubber accessory. After the rubber accessory is stretched and formed, the first cylinder 21 drives the upper mold 22 to move upward to the initial position.

[0038] See also Figure 1 The demolding assembly 3 includes a second cylinder 31, a second support plate 32 and an ejector rod 33. The second cylinder 31 is vertically fixed at the lower end of the frame 11, and the output end of the second cylinder 31 is upwardly arranged.

The ejector rod 33 can pass through the first support plate 12 and extend into the lower mold 23.

[0039] By turning on the second cylinder 31, the second cylinder 31 drives the second support plate 32 and the ejector rod 33 to move upward, the upper end of the ejector rod 33 extends into the lower mold 23, and pushes up the rubber accessories in the lower mold 23, avoiding the edge of the rubber accessories from adhering to the lower mold 23 after molding, making it convenient to remove the rubber accessories from the lower mold 23.

[0040] See also Figure 1 The transfer assembly 4 includes a second vertical arm 41, a third cylinder 42 and a transfer frame 43. The second vertical arm 41 is vertically fixedly arranged directly above the first support plate 12 and located directly on the left side of the first vertical arm 13. The third cylinder 42 is horizontally fixedly arranged on the second vertical arm 41. The transfer frame 43 is vertically fixedly arranged on the output end of the third cylinder 42. The transfer frame 43 can be driven by the third cylinder 42 to move to the directly left side of the lower mold 23. A negative pressure suction cup 44 is provided on the transfer frame 43.

[0041] After the rubber accessory is ejected by the ejection rod 33, the third cylinder 42 is turned on, and the third cylinder 42 drives the transfer rack 43 to move to the left side of the rubber accessory and close to the rubber accessory, and the negative pressure suction cup 44 works to suck the rubber accessory. Then the third cylinder 42 moves leftward to the initial position, and the negative pressure suction cup 44 stops working, and the rubber accessory is put down, so as to realize the transfer of the rubber accessory.

[0042] The negative pressure suction cup 44 in this embodiment is connected to an air pump, through which the rubber accessory can be sucked and put down.
