[0002] A laminating machine is a machine that bonds two or more layers of materials together with adhesive. For example, films and aluminum foil, films, paper, etc. are often used. It can also be laminated with films, sponges, cloths, etc. Common flexible packaging materials are basically composite finished products. Generally speaking, a laminating machine refers to a composite equipment in home textiles, clothing, furniture, automotive interiors and other related industries. It is mainly used for the laminating production process of two or more layers of various fabrics, leather, films, paper, sponges, etc. Specifically, it is divided into adhesive laminating and non-adhesive laminating. Adhesive laminating is divided into water-based adhesive, PU oil adhesive, hot melt adhesive, etc., and the non-adhesive laminating process is mostly direct hot pressing bonding between materials or laminating with flame combustion.

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example 1

[0027] A sensing device suitable for a hot melt adhesive and environmentally friendly adhesive multifunctional compounding machine, such as Figure 1-Figure 5As shown, it includes a shell 1; a feed sensing mechanism 2 is provided on the shell 1, and the feed sensing mechanism 2 includes a feed barrel 201, the feed barrel 201 is fixedly connected to the top of the shell 1, and a sensing plate 202 is slidably connected inside the feed barrel 201, and a piston barrel 203 is fixedly connected to the bottom end of the sensing plate 202, and a piston rod 204 is slidably connected inside the piston barrel 203, and the piston rod 204 is arranged through the feed barrel 201, and a feed port 205 is opened on one side of the feed barrel 201. The feed sensing mechanism 2 can sense the remaining amount of raw materials inside the feed barrel 201, and can automatically disconnect the equipment when the amount of raw materials is insufficient, thereby avoiding dry burning of the equipment due to lack of raw materials. The feed barrel 201 can facilitate the feeding operation of the raw materials, and the sensing plate 202 can carry the raw materials. The induction plate 202 is tilted toward the feed port 205, so that the raw materials on the induction plate 202 can enter the interior of the housing 1 from the feed port 205. At the same time, the induction plate 202 can cooperate with the piston cylinder 203 and the piston rod 204. When the raw materials are almost exhausted, the gas pressure inside the piston cylinder 203 can push the induction plate 202 upward, so that the induction plate 202 and the feed port 205 are misaligned with each other, so that the feed cylinder 201 is closed in time. The bottom end of the induction plate 202 is fixedly connected with a guide rod 206, which passes through the feed cylinder 201 and is slidably connected to the guide rod 206. The guide rod 206 structure can guide the movement of the induction plate 202 to prevent the induction plate 202 from tilting during the movement. Deflection affects the feeding operation of the raw materials. The top of the shell 1 is meshedly connected with a screw rod 207, which passes through the shell 1 and is arranged inside the shell 1. The bottom of the screw rod 207 is rotatably connected with a connecting plate 208, and the connecting plate 208 is fixedly connected to the bottom of the piston rod 204. The screw rod 207 structure can drive the piston rod 204 through the connecting plate 208, so as to conveniently adjust the height of the piston rod 204, thereby conveniently controlling the remaining amount of the raw materials. The top of the screw 207 is fixedly connected with an adjusting knob 209, and the outer side of the adjusting knob 209 is rotatably connected with a quantitative rod 210, which passes through the shell 1 and is connected inside the shell 1. A scale 211 is provided on the side of the quantitative rod 210, and the adjusting knob 209 structure can adjust the screw 207. The screw 207 is driven to move and adjust on the housing 1 when rotating. The quantitative rod 210 structure can facilitate the operator to observe the adjustment amount when driving and adjusting the screw 207. The scale 211 can convert the adjustment amount into a numerical value, which is convenient for the operator to observe intuitively. The bottom end of the induction plate 202 and the bottom end of the inner wall of the feeding barrel 201 are fixedly connected with a contact spring 212, and the positions of the contact spring 212 correspond to each other. The top of the housing 1 is fixedly connected with a warning light 213 and a buzzer 214. The contact spring 212 structure can conveniently control the heating structure inside the housing 1. When the remaining amount of raw materials is insufficient, the induction plate 202 rises and separates the contact springs 212 from each other, so that the internal heating structure can be conveniently disconnected.The warning light 213 and buzzer 214 can warn the operator through sound and light when the remaining amount of raw materials is insufficient, so that the operator can replenish the raw materials in time.

[0028] Example 2

[0029] like Figure 1-Figure 5 As shown, an induction heating mechanism 3 is provided inside the shell 1, and the induction heating mechanism 3 includes a heating cylinder 301, and the heating cylinder 301 is fixedly connected to the bottom end of the shell 1, and an induction heating coil 302 is fixedly connected to the outside of the heating cylinder 301, and the induction heating coil 302 is electrically connected to the contact spring 212. The induction heating mechanism 3 can perform induction heating on the raw material, thereby heating the raw material from a solid state to a molten state for subsequent use. The heating cylinder 301 structure can temporarily store the raw material and the raw material after heating and melting, and the induction heating coil 302 can heat the raw material by induction heating. An injection pipe 303 is fixedly connected to the bottom end of the shell 1, and the injection pipe 303 and the heating cylinder 301 are interconnected, and an electromagnetic valve is connected to the injection pipe 303.

[0030] When the induction device of the utility model is used for a hot melt adhesive and environmentally friendly adhesive multifunctional compound machine, the raw material is poured into the feed barrel 201, and the raw material presses the induction plate 202 downward by its own weight, and the raw material in the feed barrel 201 moves from the feed port 205 to the inside of the heating barrel 301, and the induction heating coil 302 continuously heats the raw material. When the raw material is continuously added to the inside of the heating barrel 301, the amount of raw material in the feed barrel 201 decreases accordingly. When the raw material is continuously used and continuously reduced, the air pressure in the piston barrel 203 pushes the piston barrel 203 and the induction plate 202 upward. When the weight of the raw material is lower than the set value, the induction plate 202 and the feed port 205 interact with each other. The feed port 205 is dislocated and closed. At this time, the contact spring 212 at the bottom of the induction plate 202 is separated from the contact spring 212 inside the feed barrel 201, and the induction heating coil 302 is disconnected. At the same time, the warning light 213 and the buzzer 214 are running and warn the operator through sound and light. When the set value of the remaining amount of raw materials needs to be adjusted, it is only necessary to rotate the screw 207 through the adjustment knob 209, and the screw 207 moves accordingly, and drives the piston rod 204 to move synchronously through the connecting plate 208, so that the set value of the remaining amount of raw materials can be adjusted. During the adjustment process, the adjustment amount can be controlled by the scale 211 on the side of the quantitative rod 210.
