Description

Technical Field

[0001] The invention relates to the technical field of valve production, and in particular to a valve shower curtain positioning plate and a use method thereof. Background Art

[0002] The valve is an important part of the automobile tire, which includes the valve cap, valve core and valve body. The main function of the valve is to inflate and deflate the tire, maintain the airtightness inside the tire, and thus ensure the normal operation of the tire. During the production process, the valve needs to be sprayed with glue paste on its surface. At this time, a curtain spraying machine is needed. It generates a uniform glue paste curtain through the pressure of the pump, which can adjust the thickness of the glue paste surface to ensure that the coating appearance is uniform and the film thickness is consistent.

[0003] At present, the existing valve positioning plate is an integral plate. The valve is first fixed on the positioning plate, and the positioning plate as a whole is directly replaced before the shower curtain. However, this requires a sufficient number of positioning plates for recycling, which will result in excessively high initial investment costs. In addition, during the shower curtain process, the glue surface will also be sprayed onto the surface of the positioning plate. After long-term use, the glue surface will be too thick, and it will take time to clean the glue surface. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a valve curtain positioning plate and a method of using the same. The valve curtain positioning plate is slidably installed with a detachable valve positioning tooling. After the valve workpiece is coated with glue paste through a curtain spraying machine, the valve workpiece can be replaced only by replacing the valve positioning tooling, and its investment cost is lower than before. Secondly, each time the curtain is sprayed, the protective plate is covered to effectively prevent glue paste from being applied to the positioning plate. During the later cleaning, only the protective plate needs to be replaced, and the operation will be simpler.

[0005] To solve the above technical problems, the technical solution of the present invention is achieved as follows:

[0006] A valve shower curtain positioning plate, comprising a positioning plate fixedly mounted on a shower curtain platform of a shower curtain machine, the positioning plate being provided with a plurality of slideways distributed in a linear array, and a valve positioning tool being slidably mounted in the slideways;

[0008] The upper surface of the positioning plate is rotatably installed with protective plates distributed on both sides of the slide, and the protective plates are provided with avoidance holes corresponding to the positions and numbers of the positioning holes; when the protective plates are flipped over to above the valve positioning tooling, the valve workpiece is located in the avoidance holes, and the upper surfaces of the positioning plate and the valve positioning tooling are fully covered by the protective plates.

[0009] By adopting the above scheme, the valve nozzle curtain positioning plate is equipped with a detachable valve nozzle positioning tooling by sliding. After the valve nozzle workpiece is coated with glue paste through the curtain spraying machine, the valve nozzle workpiece can be replaced only by replacing the valve nozzle positioning tooling, which has lower investment cost than before; secondly, each time the curtain spraying is performed, the protective plate can be used to cover the positioning plate to effectively prevent glue paste from being applied to the positioning plate. During the subsequent cleaning, only the protective plate needs to be replaced, which makes the operation simpler.

[0010] As a preferred embodiment of a valve curtain positioning plate, slide rails are provided on both side walls of the slideway, and slide grooves used in conjunction with the slide rails are provided on both sides of the valve positioning tooling; when the slide grooves are slidably installed on the slide rails, the upper surface of the valve positioning tooling is flush with the upper surface of the positioning plate.

[0015] By adopting the above scheme, in order to improve the flexibility of the valve positioning tooling, by opening two upper and lower guide grooves, the staff can arbitrarily choose the wire groove to install the base plate, which is more flexible in application.

[0016] As a preferred implementation of the valve curtain positioning plate, a magnet block is also bonded to the surface of the protective plate; when two adjacent protective plates are flipped upward to a vertical state, the two protective plates are vertically fixed under the adsorption force of the magnetic force.

[0017] By adopting the above solution, in order to facilitate the fixation of the protective plate after flipping, magnet blocks are installed so that the two protective plates are vertically fixed under the adsorption force of the magnetic force. The operation is simple and the application is very convenient.
