Description

Technical Field

[0001] The utility model belongs to the technical field of hot melt adhesive mixers, and in particular relates to a hot melt adhesive mixer with uniform heating. Background Art

[0002] Hot melt adhesive is a plastic adhesive. Its physical state changes with temperature within a certain temperature range, while its chemical properties remain unchanged. It is non-toxic and tasteless, and is an environmentally friendly chemical product. In order to ensure the effectiveness of hot melt adhesive, existing hot melt adhesive mixers usually have a heating rod to heat the hot melt adhesive. This heating method has the problem of uneven heating of the hot melt adhesive, which causes the local heating temperature of the hot melt adhesive to be too high and carbonized, affecting the use of the hot melt adhesive. At the same time, after the hot melt adhesive is used, some hot melt adhesive will remain on the wall of the barrel. Since this part of the hot melt adhesive is far away from the stirring paddle, the remaining hot melt adhesive is continuously heated by the heating layer of the barrel and carbonized, affecting the effectiveness of the subsequent addition of hot melt adhesive. In addition, the bottom of the hot melt adhesive barrel is usually arc-shaped, and the hot melt adhesive at the bottom of the barrel has the problem of uneven stirring. Therefore, a hot melt adhesive mixer that heats evenly, avoids carbonization of the hot melt adhesive, and stirs the hot melt adhesive at the bottom of the barrel evenly is particularly important. Utility Model Content

[0003] The utility model provides a hot melt adhesive mixer with uniform heating to solve the problems that the hot melt adhesive is heated unevenly when heated by a heating rod, the hot melt adhesive is easily carbonized, and the hot melt adhesive at the bottom of the barrel is stirred unevenly.

A sensor 2 is installed in the barrel body at a position two-thirds of the barrel height from the bottom, and the outlet 2 is at the same height as the sensor 2. The sensor 1 and the sensor 2 are respectively connected to the controller for communication.

[0007] As a priority, the spiral heating tube is connected to the interlayer heating layer through the main inlet two, outlet four, outlet five and outlet six in sequence.

[0008] As a preference, the exit 4 is at the same height as the exit 1; the exit 5 is at the same height as the exit 2; and the exit 6 is at the same height as the exit 3.

[0009] As a preference, the outlet one is installed with switch one; the outlet two is installed with switch two; the switch one and switch two are communicatively connected with the controller.

[0011] Preferably, the heating device is a thermal oil circulation heating device or a circulating water heating device.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Compared with the prior art, the hot melt adhesive mixer with uniform heating in the utility model can

[0014] (1) The interlayer heating layer can heat the hot melt adhesive near the edge of the barrel, and the spiral tube heating layer can heat the hot melt adhesive in the middle of the barrel. The interlayer heating layer and the spiral tube heating layer heat the hot melt adhesive at the same time, so that the hot melt adhesive in the entire barrel is heated more evenly;

[0015] (2) The interlayer heating layer and the spiral tube heating layer can be heated by the same heating device, which reduces the equipment investment cost, makes the production operation easier, and improves the production efficiency;

[0016] (3) The sensor, controller, and switch of the interlayer heating layer outlet work together to control the heating height of the interlayer heating layer and the spiral tube heating layer.

When the hot melt adhesive liquid level in the barrel is between one-third and two-thirds of the barrel height, the heating height of the interlayer heating layer and the spiral tube heating layer is controlled to be two-thirds of the barrel height. Therefore, the hot melt adhesive mixer with uniform heating can avoid continuous heating of the hot melt adhesive remaining on the barrel wall and carbonization, while reducing production costs and energy consumption;
