[0035] How it works

[0036] Before starting the rubber pretreatment equipment for rubber pretreatment, check the operation of the equipment. First, check whether the power supply of each device is intact and whether the safety measures are in place. Ensure that the connection between each device is intact and effective, turn on the switches of each device, and ensure that the equipment can operate normally.

[0037] The collected rubber is put into the rubber cutting area 14 from the rubber feed port 13, and the outer cylinder 32 and the inner cylinder 33 rotate in opposite directions, driving the inner cutting knife 34 and the outer cutting knife 35 to rotate in opposite directions, and the rubber is cut into pieces and falls on the wrapping plate 15. At the same time, other solid additives are sent into the solid crushing bin 84 from the solid feed port 12, and the solid additives are crushed by the crushing roller 36. The powdered additives fall from the screening port 40 onto the drop plate 41, and the large particles enter the particle recovery trough 37 from the particle recovery port 38. The powdered additives that fall on the drop plate 41 fall on the powder falling area 59 on the wrapping plate 15 as the drop plate 41 rotates, and the powdered additives roll and cover the outer side of the rubber with a layer when the wrapping plate 15 rotates.

[0038] When there is more rubber on the wrapping disc 15, the torsion spring 49 drives the wrapping disc 15 to flip downward, and at the same time, the locking buckle 48 is disconnected from the locking plate 44, and the locking spring 46 returns to push the locking plate 44 out to intercept the powdered additive. The wrapping disc 15 flips downward to allow the rubber wrapped with the additive to enter the mixing and stirring chamber 86 from the drop opening 31, and the stirring motor 28 drives the stirring shaft 26 and the stirring rod 27 to stir. At the same time, the liquid valve 20 is opened to send the liquid additive into the liquid heating chamber 21, and the heating motor 24 is turned on for heating. The liquid additive filtered by the filter net bag 22 enters the mixing and stirring chamber 86 from the liquid outlet 23 in the annular liquid guide tube 30.

[0039] The above descriptions are merely embodiments of the present invention, and are not intended to limit the patent protection scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
