Description

TECHNICAL FIELD

[0001] The present application belongs to the field of hot melt adhesive packaging, in particular to a non-sticking packaging method and packaging equipment for block-shaped hot melt pressure-sensitive adhesive. BACKGROUND

[0002] The film packaging machine is a machine that coats a layer of non-sticky ultra-thin film on the surface of hot melt pressure-sensitive adhesive. There are two common packaging systems for pillow-shaped packaging on the market. One is to directly coat the molten hot melt pressure-sensitive adhesive and plastic coating material through a co-extrusion die at high temperature. The coated product is first divided into small sections by a periodic molding machine and then enters the water channel for cooling. After the adhesive strip cools down, it is dried by blowing air, and then each small section of the pillow-shaped hot melt pressure-sensitive adhesive on the adhesive strip is pulled apart by two unequal-speed rotating wheels to obtain a single pillow shape. The other is to directly pour the molten hot melt pressure-sensitive adhesive into a plastic bag that has been pre-formed with PE / EVA blend, seal it, and then directly cool it in an ice water channel. After cooling, it becomes a single pillow shape with no sticky surface.

[0003] The block packaging machine first folds the release paper into a concave shape during production. After the raw material is heated and stirred to melt in the reaction kettle, the adhesive is uniformly poured into the concave space surrounded by the release paper. After cooling and solidification of the adhesive, the nails are removed and the release paper is packaged. The release paper is a common way to package hot melt pressure-sensitive adhesive, which can form block-shaped hot melt adhesive and has the characteristics of high temperature resistance. During packaging with the block packaging machine, the release paper is folded according to the size of the adhesive film area. During filling, the molten hot melt adhesive is filled into the folded area of the release paper according to the size of the adhesive film area.

[0023] As an embodiment of the present application, the release paper supporting plates 8 are arranged at four vertices of the adhesive film area 7 respectively, the adhesive film area 7 has a rectangular structure, and the top of the release paper supporting plate 8 is provided with a hanging ear which is installed on the surface of the displacement sliding plate 11.

[0024] As an embodiment of the present application, the guide sliding rails 12 are respectively arranged obliquely, and the ends of the guide sliding rails 12 close to the adhesive film area 7 are arranged close to each other.

[0025] As an embodiment of the present application, a threaded groove is formed in the surface of the threaded sliding shaft 13 along the axial direction of the threaded sliding shaft 13, the two ends of the threaded sliding shaft 13 are installed on the surface of the packaging isolation plate 5 through positioning blocks, the two ends of the threaded sliding shaft 13 are rotatably connected to the positioning blocks, the threaded sliding shaft 13 penetrates through the screw shaft sliding block 14 and is connected to the screw shaft sliding block 14 through threads.

The introduction of the supporting pulley 16 reduces the friction generated during the movement of the packaging slide plate 4, making the sliding more smooth. At the same time, the good contact of the supporting pulley 16 with the surface of the packaging slide plate 4 also effectively prevents deviation caused by vibration or external force, thereby ensuring that the filling head 3 can accurately align with each film area 7, realizing efficient and stable filling operation. This design significantly improves the overall performance of the equipment, meeting the diversified production needs.
