Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of conveyor belt production equipment, in particular to a continuous reinforced rubberized conveyor belt production equipment and a production method thereof. BACKGROUND

[0002] In the field of engineering equipment or mining machinery, conveyor belts or gear synchronous belts are widely used. Generally, a single long-distance belt is connected by splicing a longitudinal rubber or fiber cloth belt to achieve long-distance power transmission or material conveying. The form of such a belt is usually long in length, from tens of centimeters to tens of meters, and short in width, generally a few centimeters to a few tens of centimeters. The length direction is the stress direction, and high tensile strength is required.

[0003] However, the synchronous belts on the current engineering equipment or the conveyor belts for material conveying generally use the method of increasing the thickness to achieve the transportation of heavy loads or power transmission. Moreover, the belt itself relies on gear meshing to achieve power transmission, and generally cannot bear large slope or vertical lifting forces. If the belt needs to bear a large tension, the size of the belt needs to be increased. At the same time, since the reinforced fiber belt is generally manufactured by splicing, there are hidden dangers at the interface, and it cannot be used for a long time. SUMMARY

[0004] The purpose of the present application is to provide a continuous reinforced rubberized conveyor belt production equipment. The high-strength tensile unidirectional conveyor belt prepared by unidirectional continuous fibers can effectively solve the problem of vertical lifting transmission. The unidirectional fiber is wound continuously without joints to form a belt, which is convenient for the preparation of high-pre-tightening force and high-tension power transmission belt.

[0005] The above technical purpose of the present application is achieved by the following technical scheme:

[0006] A continuous reinforced rubberized conveyor belt production equipment comprises a pay-off device and an internal shrinkage mold device. The internal shrinkage mold device comprises a mold shaft, a shrinkage assembly, a driving assembly, and a plurality of shrinkage tiles. The shrinkage tiles are distributed circumferentially around the mold shaft and enclose a winding space. The pay-off device provides fiber filaments to the internal shrinkage mold device. The driving assembly drives the mold shaft to rotate, which drives the fiber filaments to wind outside the winding space enclosed by the shrinkage tiles. The shrinkage assembly drives the shrinkage tiles to move towards or away from the mold shaft. The outwardly expanding shrinkage tiles provide fiber filaments for winding, and the inwardly shrinking shrinkage tiles provide finished products for demolding.

[0007] Further, the pay-off device comprises a pay-off rack and a pay-off car. The pay-off car is slidably connected to the pay-off rack, and the sliding direction of the pay-off car is parallel to the mold shaft.

[0008] Further, the pay-off rack is connected with a running linear guide and a running motor, the pay-off vehicle comprises a sliding plate at the bottom, the sliding plate is slidably connected with the running linear guide, and the output end of the running motor is connected with and drives the sliding plate to slide through a screw rod.

[0009] Further, the driving assembly comprises a rotary motor, and the rotary motor is drivingly connected with the mold rotating shaft.

[0010] Further, the retracting assembly comprises a sliding sleeve sleeved outside the mold rotating shaft, the sliding sleeve is slidably connected with the mold rotating shaft, one end of the retracting tile is hingedly connected with the first hinge shaft, the other end of the first hinge shaft is hingedly connected with the mold rotating shaft, the other end of the retracting tile is hingedly connected with the second hinge shaft, and the other end of the second hinge shaft is hingedly connected with the sliding sleeve.

[0011] Further, the inner retracting mold device comprises a rotary bracket, at least two bearing seats are connected on the rotary bracket, and the mold rotating shaft is rotatably connected with the two bearing seats through bearings.

[0012] The application also discloses a continuous reinforced rubber-coated conveying belt production method.

[0013] The above technical purpose of the application is achieved by the following technical scheme.

[0014] A continuous reinforced rubber-coated conveying belt production method comprises the following steps.

[0015] First, the fiber filaments are uniformly wound outside the winding space surrounded by the retracting tiles through rotary winding.

[0016] Then, the liquid latex is brushed or sprayed, and after vulcanization or solidification, the retracting tiles are driven to retract inward by the retracting assembly, so that the finished product is demolded.

[0017] Further, the finished product after demolding is obtained in the required conveying belt width through cutting.

[0018] Further, the fiber filaments comprise one or more of polyester fiber, nylon fiber, aramid fiber and liquid crystal high molecular fiber.

[0019] Further, the fiber filament has a filament density of 1000 dtex-30000 dtex.

[0020] In summary, the application has the following beneficial effects.

[0021] The continuous circle type conveying belt has no fiber break point, and is made in a whole ring shape by continuous winding, and the maximum length can reach more than 15 meters. After the fiber silk is uniformly wound by the rotating winding mode, the liquid rubber is sprayed or brushed, and after curing or vulcanization is completed, the inner shrinkage mold is used for inner shrinkage demolding, and the whole is formed into a cylindrical shape, and then the required conveying belt width is obtained by cutting. The production and preparation method of the continuous winding and gluing can ensure the uninterrupted and jointless requirement of large equipment or heavy load power transmission, and meet the light weight requirement.
