Description

Technical Field

[0001] The utility model relates to the technical field of hot melt rubber pellet production equipment, in particular to a charging hopper in which hot melt rubber pellets are not easily agglomerated. Background Art

[0002] Hot-melt adhesive pellets are a plastic adhesive product whose physical state changes with temperature within a certain temperature range, but their chemical properties remain unchanged. They are an environmentally friendly adhesive product and are widely used in packaging across various industries. After production, hot-melt adhesive pellets need to be weighed and packaged. During weighing and packaging, the pellets first reach a certain weight in the hopper, then the seal at the bottom of the hopper is opened, allowing the hot-melt adhesive pellets to fall into the packaging bag below the hopper. However, due to the stickiness of the hot-melt adhesive pellets, they easily stick together during the weighing process, forming lumps. This results in slow material discharge and large residual quantities, necessitating manual breaking and unloading, which affects continuous weighing and reduces production efficiency. Utility Model Content

[0006] As a further improvement of the above technical solution:

[0007] The stirring member is in a T-shaped structure as a whole, and includes a vertical rod arranged along the vertical direction and a horizontal rod arranged along the horizontal direction.

[0008] The first driving mechanism includes a first telescopic cylinder, and the second driving mechanism includes a second telescopic cylinder.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figure 1 and Figure 2As shown, the charging hopper of the present embodiment, which is not easy for the hot-melt adhesive particles to compact, comprises a hopper body 1, the hopper body 1 having a feed end 101 and a discharge end 102, the discharge end 102 being provided with a first sealing plate 2 and a second sealing plate 3, the hopper body 1 being provided with a first driving mechanism 4 for driving the first sealing plate 2 to rotate and a second driving mechanism 5 for driving the second sealing plate 3 to rotate, and the first sealing plate 2 and / or the second sealing plate 3 being provided with a stirring member 6 for stirring the hot-melt adhesive particles. The loading hopper for hot-melt adhesive particles that are not easy to agglomerate includes a hopper body 1 and a first sealing plate 2 and a second sealing plate 3 arranged on the discharge end 102, wherein the first sealing plate 2 and / or the second sealing plate 3 are provided with a stirring member 6 located in the hopper body 1. When the first driving mechanism 4 and the second driving mechanism 5 drive the first sealing plate 2 and the second sealing plate 3 to open, the stirring member 6 can stir the hot-melt adhesive particles in the hopper body 1 to prevent the weighed hot-melt adhesive particles from agglomerating into lumps. At the same time, the stirring member 6 can exert a downward force on the hot-melt adhesive particles, thereby increasing the speed at which the hot-melt adhesive particles fall into the packaging bag below the hopper body 1, avoiding affecting continuous weighing, and effectively improving production efficiency.
