Description

Technical Field

[0001] This utility model belongs to the technical field of sealing strip production equipment, and specifically relates to an online spraying device for automotive sealing strips. Background Technology

[0002] With the development of the automotive industry, the number of vehicles on the streets is increasing, and cars have become an indispensable means of transportation for every household. Correspondingly, the automotive parts that match these vehicles are becoming increasingly important. Among them, the sealing strips used in various parts of the vehicle, such as the doors and hood, are crucial for ensuring the vehicle's airtightness. Automotive sealing strips are important accessories on automobiles. They fill the gaps between body components and have functions such as shock absorption, waterproofing, dustproofing, sound insulation, and decoration. High-quality automotive sealing strips can improve the comfort of the driving experience and protect the vehicle body.

[0003] When rubber sealing strips are used in atmospheric or other environments, they will experience aging phenomena such as loss of gloss, discoloration, hardening, powdering, and cracking due to the influence and effects of the external environment. Their performance will gradually deteriorate, and they may even become unusable. In order to extend the service life of rubber sealing strips, an anti-aging coating or wear-resistant coating can be sprayed onto the outside of the rubber sealing strip.

[0004] Existing technology allows for the application of coatings to the surface of sealing strips using a spray coating device. For example, patent application number CN201610776367.1 discloses a pre-coating device for automotive sealing strips, used to coat sealing strips extruded from an extruder before the vulcanization process. This pre-coating device includes a housing with a spray channel having an inlet and an outlet, an exhaust mechanism connected to the spray channel, a spraying mechanism with spray guns located within the spray channel, a conveying unit (two of which are synchronously operable at the inlet and outlet of the spray channel), multiple rotating support units spaced apart within the spray channel along the direction of movement of the sealing strip, with a distance of 20-30 cm between adjacent rotating support units, and a constraint guide unit located at the outlet of the spray channel to apply constraint forces to opposite sides of the sealing strip sliding through the spray channel, thereby guiding the movement of the sealing strip. The spraying mechanism includes a paint supply unit and a compressed gas supply unit connected to the spray guns. The paint supply unit includes a paint tank and multiple peristaltic pumps connected between the paint tank and each of the spray guns via a conveying pipe. The exhaust mechanism includes an exhaust channel formed within the housing and communicating with the spraying channel, and an exhaust fan communicating with the exhaust channel. A paint adsorption element is provided between the exhaust channel and the spraying channel, and an adsorption element replacement port is provided at one end of the housing.

[0005] Existing line spraying equipment includes an electrical control cabinet, a box arranged in a left-right direction, a line break sensor on the left or right side of the box, a conveying structure arranged in a left-right direction inside the box, and multiple spraying structures arranged side-by-side inside the box. Each spraying structure includes a material tank, a compressed gas supply structure, a spray gun, a spray gun holder, a peristaltic pump, a pressure gauge, and a pressure valve. The peristaltic pump and line break sensor are electrically connected to the electrical control cabinet. The compressed gas supply structure is connected to the spray gun via a pipeline with a pressure gauge and a pressure valve. The material tank is connected to the spray gun via a pipeline with a peristaltic pump. The spray gun is mounted on the box via a spray gun holder.

[0006] In existing technologies, adjustments are required to the position of the spray gun, the supply of compressed air, and the supply of paint, which is inconvenient. In addition, the number of spraying structures is usually at least four, resulting in a large number of wires and pipes, making wiring difficult. Utility Model Content
