Description

Cigarette gun refrigerating system under filter rod forming machine

Technical Field

The utility model relates to a cigarette equipment technical field, concretely relates to opium pipe refrigerating system under filter rod making machine.

Background

In the process of rolling the filter rod, the ZL26A filter rod forming machine coats the forming paper coated with lap hot melt adhesive, wraps the tows, is driven by the cloth belt to enter the forming cavity to be compressed and rolled into filter rods, and the filter rods are formed after cutting. The forming cavity comprises an upper tobacco pipe and a lower tobacco pipe. Wherein, the upper and lower smoke guns are both provided with cooling water circulation devices. After entering the forming cavity, the cigarette feeding gun needs to heat the lap hot melt adhesive and the forming paper firstly and then cool the lap hot melt adhesive and the forming paper to form the filter strip. The cloth belt wrapping the filter strip rubs with the lower cigarette gun in the operation process of the lower cigarette gun, so that the temperature of the filter strip rises, the filter strip expands, the circumferential value of the filter rod is increased, and even the filter rod exceeds the standard, and the product quality accident is caused. This requires cooling of the lower pipe in addition to the upper pipe, which cools the base of the lower pipe. When the ZL26A filter stick forming machine runs for about one week, the temperature of the base of the cigarette falling gun is higher and higher, and the machine is stopped until the upper limit set value is reached to 30 ℃. When the upper limit set value is adjusted to be 40 ℃ at most, the shutdown times are reduced, but the peripheral SD value (the quality physical index of the filter stick) of the filter stick is larger or exceeds the standard due to higher temperature, so that the quality hidden trouble is caused. At this time, the machine needs to be stopped, and the pipeline is dredged by water discharge, air exhaust and compressed air blowing, and the time for each time is about 20 minutes.

The refrigeration water route of present lower opium pipe base does: the water from the water mixer firstly enters the oil cooler of the forming machine, then enters the base of the lower smoke pipe, then enters the radiator of the negative pressure fan (the discharging fan), and finally flows back to the other water mixer. The oil cooler, the lower smoke gun base and the negative pressure fan are connected in series. Firstly, the refrigerating water of the lower smoke gun base is indirectly provided by a water mixer. Secondly, because the diameter of the refrigeration water pipe (the inner diameter phi 8mm of a heat dissipation copper pipe) in the oil cooler and the discharge fan radiator is smaller than that of the refrigeration water pipe (the inner diameter phi 14mm of a plasticizing net pipe) of the lower smoke gun base, refrigeration water firstly enters the lower smoke gun base with a large diameter from the oil cooler with a small diameter and then enters the negative pressure fan with a small diameter, so that the refrigeration water flowing speed passing through the lower smoke cavity base is reduced, the refrigeration effect is influenced, and the temperature of the lower smoke gun base is increased.
