Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and examples, which are not intended to limit the present invention.
As shown in figures 1-6, the cigarette machine cigarette microwave drying bonding electric iron comprises a heating end, a microwave generating cavity, a microwave transmission cavity, a microwave transmitting port, a driving circuit, a microwave head and a pulse microwave power supply, wherein the microwave head is installed in the microwave generating cavity, the microwave transmission cavity is installed below the microwave generating cavity, the heating end is arranged at the bottom of the microwave transmission cavity, the microwave transmitting port is arranged between the microwave generating cavity and the microwave transmission cavity, the output end of the pulse microwave power supply is connected with the driving circuit, and the output end of the driving circuit is connected with the power end of the microwave head. The microwave generating cavity and the microwave transmission cavity are directly isolated through 1.5mm304 stainless steel, only a magnetron microwave transmitting port is reserved, all materials on the outer surface are made of 304 stainless steel with the thickness of 1.5mm, and a microwave outlet of the transmission cavity is a ceramic sheet heating end. The microwave pulse power supply is also provided with an interlocking safety switch which is connected with the power end of the microwave head magnetron.
Example 1: as shown in fig. 1 and 2, the ceramic sheet prepared by the latex system water-based casting method is used for replacing the heating end face of the electric soldering iron. The ceramic thin sheet needs to be accurate in size and smooth in surface, a special die is designed according to the circumference of a cigarette, the average thickness of the ceramic thin sheet is 1mm, the length and the width of the ceramic thin sheet are consistent with those of heating end faces of existing electric soldering irons and are 380 multiplied by 5mm respectively, and the contact arc-shaped end face of the cigarette is required to be smooth.
As shown in fig. 3 and 4, the electric iron heating tube was replaced with a microwave generating magnetron and the thermocouple temperature detector was eliminated. Considering that a control system of a cigarette making machine is not provided with a socket suitable for a special driving circuit board for a microwave electric iron, an independent MUEGGEMX4000H-111KL pulse microwave power supply is used, the power supply is suitable for a 380V three-phase alternating current power supply, a matched PLC (programmable logic controller) can be selected for display and output regulation, the maximum output power is 1000W, the design requirements of the microwave electric iron are met, and 2 electric irons are arranged inside each electric iron. Because the original electric soldering iron cavity is not installed enough, the electric soldering iron cavity needs to be transformed into a generating cavity and a transferring cavity, the generating cavity and the transferring cavity are isolated by using 1.5mm304 stainless steel, only a magnetron microwave emitting port is reserved, all materials on the surface of the electric soldering iron are made of 304 stainless steel with the thickness of 1.5mm, and a microwave outlet of the transferring cavity is a ceramic sheet heating end.
As shown in figure 5, in order to prevent microwave from overflowing and damaging human body, the surface of the electric soldering iron needs to use 304 stainless steel with the thickness of 1.5mm except the ceramic sheet and the surface of the contact end of the tobacco rod.

As shown in fig. 6, a safety switch interlocked with an electric soldering iron is added. Because the circuit electric soldering iron is frequently lifted or put down, the magnetron continuously emits microwaves to hurt nearby people when lifted, the power supply of the magnetron needs to be cut off when lifted, but the heating wire keeps continuously heating, and the microwave emission is conveniently and quickly started.
Example 2: the highest vehicle speed of a PROTOS2-2 cigarette making machine is 12000 cigarettes/minute, the cigarette making machine is high in vehicle speed, the cigarette making process lap adhesive coating efficiency is only 99.5%, and the problems of strip running, cigarette bursting and the like caused by low efficiency of lap adhesive coating are often caused. Aiming at the problem, a low-viscosity quick curing type lap adhesive is developed, the lap adhesive is coated with efficiency reaching 100%, but the lap adhesive has higher requirements on the heat transfer efficiency of an electric iron of a cigarette making machine, the existing cigarette making machine with the electric iron still cannot achieve ideal drying and curing effects even if the existing cigarette making machine with the electric iron is driven to the highest heating temperature, the problem of adhesive force development is insufficient, the problem of opening is not well solved, the defect that cigarette ash carbonizes to pollute the surface of a cigarette and the problem that the temperature of the cigarette is too high are caused, the characteristic that microwaves have special heating effects on substances with higher water content is utilized, the cigarette drying and bonding electric iron of the cigarette making machine with the cigarette is planned to be developed, preliminary simulation tests are already carried out through a preliminary household microwave oven, and the effect is very good. Based on this, we are developing the cigarette microwave drying and bonding electric soldering iron in conjunction with certain electrical equipment companies. According to the required heating power of the PROTOS2-2 cigarette making machine, the heating efficiency is calculated by referring to the test result of the microwave oven:
Q=cm△t=4.2×103J/（kg•℃）×0.2Kg×（45℃-15℃）
electric power W = Pt =600W × 3 × 60s =1.08 × 105J supplied to the microwave oven.
The heat absorbed by the glue is 2.52X 104J/h.
The power supplied to the microwave oven within 1 h was 1.08X 105J.
According to the calculation result, in order to ensure that the power is sufficient and adjustable, a MUEGGEMX4000H-111KL pulse microwave power supply is selected, the power supply is suitable for a 380V three-phase alternating current power supply, a matched PLC (programmable logic controller) can be selected for display and output regulation, the maximum output power is 1000W, in order to ensure the microwave radiation uniformity, 2 MH1000K-218BB magnetrons are installed in each electric soldering iron, the maximum power of a single tube is 1000W, and the 2 magnetrons are controlled in a double-way mode.
While the present invention has been particularly shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
