Description

Technical Field

[0001] The utility model relates to the technical field of coating machines, in particular to a silicone oil coating machine. Background Technique

[0002] A silicone oil coating machine is an automated mechanical device that specifically controls silicone oil and coats it on the surface of products. Silicone oil coating machines are commonly used in the production of wrapping paper and adhesive tapes to apply silicone oil. Applying silicone oil to wrapping paper has the characteristics of high temperature resistance, moisture resistance, and oil resistance, thus better preserving food. Applying silicone oil to the back of adhesive tapes facilitates subsequent use and makes it easy to tear the adhesive tapes.

[0003] After retrieval, Chinese Patent Publication No. CN219112040U discloses a silicone oil coating machine with convenient adjustment, including a box body. In the middle of the top of the box body, there is a silicone oil storage tank. There are openings on both sides of the box body. Inside the box body, there is a hollow coating roller. On the back of the hollow coating roller, there is a silicon oil delivery pipe connected to the silicone oil storage tank. The beneficial effect is that by rotating the screw rod, the two sliding seats can be driven to move closer to each other. Since the long extrusion strip is installed on the sliding seat, the long extrusion strip gradually extrudes the protruding movable sealing rod. The extruded movable sealing rod moves downward and inserts into the coating hole, realizing the adjustment of the silicone oil coating length of the hollow coating roller. At the same time, on the two sliding seats, there is a positioning member composed of an L-shaped connecting rod and a positioning arc. When the two positioning arcs are located on both sides of the paper or adhesive tape and are in slight contact with them, it means that the adjustment of the coating length of the hollow coating roller is completed, so that the adjustment of the coating length of the hollow coating roller can be quickly mastered.

[0004] However, in the above technical solution, only the rotation of the screw rod is used to drive the sliding seat and the long extrusion strip to move horizontally. The long extrusion strip presses down on the sealing movable rod to adjust the oil outlet hole. However, the long extrusion strip requires sufficient space for horizontal reciprocating movement and storage. The length of the long extrusion strip determines the adjustable range, and the length of the long extrusion strip will increase the area of the box body or the space occupied during the operation of the equipment.
