Description

TECHNICAL FIELD

[0001] The present application relates to the field of hydraulic rubber hose production, and particularly relates to a hydraulic rubber hose vulcanization support. BACKGROUND

[0002] Hydraulic rubber hoses need to go through a vulcanization process during production to improve the performance of rubber, so that it has higher elasticity, heat resistance, wear resistance, corrosion resistance, etc., thereby expanding its application range. The existing vulcanization methods are all through fixing the rubber hose on a support and then sending it into a vulcanization tank for high-pressure steam vulcanization. Due to the limited internal space of the vulcanization tank, the hydraulic rubber hose needs to be reasonably wound to improve the vulcanization efficiency. At the same time, during the vulcanization process, water film is easily formed on the surface of the rubber hose, which will affect the vulcanization effect if not removed in time. In order to solve the above problems, there are many solutions in the prior art, for example, a rubber hose vulcanization rack disclosed in announcement No. CN204431594U, which improves the number of vulcanized rubber hose coils by setting multiple coaxially stacked disc racks. However, this scheme only facilitates segmented axial stacking, and the radial space utilization is still low. A hydraulic rubber hose production vulcanization device disclosed in announcement No. CN116352935A adjusts the C-shaped buckle to adapt to rubber hoses of various lengths. Although it can wind the inner and outer rubber hoses, the rubber hose fixing method is complicated, which affects the vulcanization efficiency. Moreover, the cleaning method for the water on the surface of the rubber hose is too passive, and the cleaning effect is poor.

[0003] Finally, a multi-layer vulcanization support for hydraulic rubber hose production disclosed in announcement No. CN113059730B can realize the winding and fixing of inner and outer multi-layer rubber hoses and improve the space utilization. However, this scheme has the following problems: 1. The rubber hose needs to be fixed on the roller in advance, and then the roller needs to be installed, which is a complex process and requires a certain installation precision; 2. The centrifugal force is used to clean the water on the surface of the rubber hose, which is passive due to the tension between the water and the surface of the rubber hose. The speed may affect the forming effect of the rubber hose, and a large amount of kinetic energy is required for driving, which causes energy waste; 3. The upper limit of the fixed length of the rubber hose on a single roller is low, and it is difficult to wind and fix the super-long rubber hose. SUMMARY
