Abstract
Description
Technical Field
[0001] This invention relates to the field of rubber tube coating equipment technology, specifically to a rubber tube coating forming device and its process. Background Technology
[0002] Rubber hose molding is usually achieved through vulcanization. Traditional vulcanization processes require different process parameters, such as vulcanization temperature and time, depending on the material composition, ratio, and structure of the rubber hose, making it difficult to achieve a uniform effect.
[0003] If the vulcanization process is not properly controlled, the surface of the resulting rubber hose may become sticky or uneven, leading to substandard appearance. Therefore, a thin film is usually wrapped around the rubber hose before vulcanization to isolate it from air and water vapor. This improves the surface condition of the resulting hose, but does not completely solve the problem. Currently, the film wrapping is done manually, which is inefficient and makes it difficult to control the quality of the wrapping. Summary of the Invention
[0004] The purpose of this invention is to provide a rubber tube coating forming apparatus and its process to solve the problems mentioned in the background art. To achieve the above objective, this invention provides the following technical solution: a rubber tube coating forming apparatus, comprising a fixed ring, a rotating ring connected to the outside of the fixed ring via a bearing, a driven tooth provided along the circumference of the outside of the rotating ring, the driven tooth meshing with a drive wheel, the drive wheel being connected to a drive motor, and a displacement mechanism and a coating mechanism mounted on the side wall of the rotating ring.
[0005] Preferably, the coating mechanism includes an upper mounting frame, a rotating shaft is installed inside the upper mounting frame, a feeding roller shaft is rotatably connected to the rotating shaft, a material passage hole is opened at the bottom of the upper mounting frame, multiple layers of film are wrapped on the feeding roller shaft, the bottom of the film passes through the material passage hole and exits the upper mounting frame, an air jet pipe is provided on one side of the material passage hole, the air jet pipe is provided with air jet holes, the air jet pipe is located below the upper mounting frame and on the side of the film, the air jet pipe is connected to an air pump through an air delivery pipe, the air pump is installed on one side of the upper mounting frame, and a connecting shaft is connected to the side wall of the rotating ring on the other side of the upper mounting frame.
[0006] Preferably, an exhaust mechanism is installed at the bottom of the upper mounting bracket. The exhaust mechanism includes a lower mounting plate, a compression spring is connected to the bottom of the lower mounting plate, and an elastic exhaust plate is connected to the bottom of the compression spring.
[0007] Preferably, the displacement mechanism includes a connecting shaft I, one end of which is connected to the side wall of the rotating ring, and the other end is connected to a mounting block. The bottom of the mounting block is connected to an upper connecting rod, the bottom of which is connected to a spring, the bottom of which is connected to a lower connecting rod, and the bottom of which is connected to a roller frame. A driven wheel is mounted on the roller frame, and displacement rollers are connected to both ends. The driven wheel is connected to a drive wheel I via a conveyor belt, and the drive wheel I is connected to a displacement motor. The displacement motor is mounted on the lower connecting rod.
[0008] Preferably, there are three displacement mechanisms and one coating mechanism, and the displacement mechanisms and coating mechanisms are distributed circumferentially along the side wall of the rotating ring.
[0009] A rubber tube coating molding process specifically includes the following:
[0010] (1) The drive motor is mounted on one side of the rubber tube by a bracket and can be moved along the length of the rubber tube by an external moving device. The rubber tube is fitted into the ring of the fixed ring and the film on the feed roller shaft is passed through the feed strip hole and attached to the surface of the rubber tube.
[0011] (2) Start the drive motor and air pump. The drive motor drives the rotating ring to rotate through the drive wheel. The film begins to be wound. During the winding process, the air pump sprays air into the film through the air nozzle on the air pipe to prevent foreign objects from adhering to the film and to prevent the film from folding.
[0012] (3) When the film is wrapped, the elastic venting plate presses and flattens the wrapped film under the action of the compression spring, thereby avoiding air residue;
[0013] (4) After the film coating mechanism runs for one cycle, the film completes one turn of the rubber tube. The displacement motor is started, and the displacement motor drives the roller frame to rotate through the conveyor belt, so that the displacement roller moves along the length of the rubber tube, and finally the entire rubber tube is coated.
[0014] The technical effects and advantages of this invention are as follows: This device uses a film coating mechanism and a displacement mechanism for film coating. Compared with the existing method of manually wrapping rubber tubes with film, it can effectively improve the uniformity of film coating and work efficiency of rubber tubes, reduce the occurrence of adhesion and unevenness on the surface of rubber tubes after vulcanization, and reduce the probability of producing unqualified products.
