Detailed Description
In order to make the technical problems, technical schemes and beneficial effects solved by the utility model more clear, the utility model is further described in detail below with reference to the embodiments.
Examples
Referring to the single-sided machine schematic diagram shown in fig. 1, a heat source 30 is provided between the applicator roll 10 and the laminating roll 20, the heat source generating heat at 130-145 ℃, the heat source preferably having a temperature of 135 ℃, 136 ℃, 137 ℃, 138 ℃, 139 ℃, 140 ℃. The pasting surface of the corrugated paper is added after pasting the corrugated paper A and before pressing the corrugated paper and the facial tissue B, so that the paste temperature of the corrugated paper and the paste coated on the wavy flange is improved, the viscosity release effect of starch in the paste is improved, and the laminating effect of the corrugated paper and the facial tissue is improved.
A box body arranged along the axial direction of the laminating roller is arranged between the glue spreading roller and the laminating roller, temperature sensors are arranged at two ends of the box body, the temperature sensors detect the current ambient temperature, and the heat source adjusts the real-time occurrence temperature according to the data of the temperature sensors. The hot steam runs through the whole production line, so that steam which is common in the production line can also be used as a heat source. If the surface of the corrugated paper is directly heated by steam, the water vapor in the steam can change the water content of the corrugated paper and influence the release of starch viscosity, so that the steam used in the process is dry steam.
The embodiment provides a heating device, which uses the water vapor coming from the production line as a heat source and can quickly remove the moisture in the water vapor.
Referring to fig. 2, the heating device comprises a box 41 and a saturated steam pipe 44 with the pressure of 0.4mpa-0.6mpa, the box comprises a first side plate 411 and a second side plate 412 which are opposite, an exhaust groove 45 is arranged in the first side plate, a transverse plate 46 fixedly connected with the second side plate and a vertical plate 47 connected between the transverse plate and the bottom plate of the box are arranged in the box, an independent cavity 50 is formed by the transverse plate and the vertical plate in a surrounding mode, and the saturated steam pipe penetrates through the cavity; an exhaust port 48 is formed between the riser and the bottom plate of the box; the pipe wall of the saturated steam pipe is provided with an exhaust hole 49 corresponding to the second side plate. The steam of production line gets into inside the cavity through saturated steam pipe, and the steam that overflows from the steam pipe contacts relatively colder riser at first, and the moisture of steam condenses fast, and dry steam gets into inside the box body from the gas vent, discharges from the exhaust groove of box body again.
As an improvement of the implementation, a water collecting tank is arranged at the position of the bottom plate corresponding to the vertical plate, a liquid outlet 413 is arranged at the position of the box body corresponding to the water collecting tank, water drops condensed on the surface of the vertical plate fall into the water collecting tank below, and then are discharged outwards in time from the liquid outlet.
The temperature sensor arranged in the heating device monitors the ambient temperature in real time, but the steam temperature of the production line can not be adjusted for the process link, so that when the heating temperature needs to be improved, the heating temperature can be improved in real time by improving the blowout quantity of dry steam in unit time. In this embodiment, the vertical plate is disassembled to be composed of an upper plate 471 and a lower plate 472, the upper plate is fixedly connected with the transverse plate, the top of the lower plate is connected with the upper plate through a rotating shaft 473, and a torsion spring is installed on the rotating shaft. The exhaust hole of the steam pipe is unchanged in size, the steam pipe increases the exhausted steam quantity to enable the air flow pressure to become large, the air flow pushes the lower plate to slightly rotate around the rotating shaft to increase the size of the exhaust port, and therefore the dry steam discharge capacity of the box body in unit time can be increased, and the purpose of improving the heating temperature is achieved.
As an improvement of the embodiment, a hollow structure 474 is adopted as the vertical plate, and a capillary condensation tube 475 is installed in the vertical plate and connected with an external cold source. The capillary condenser tube can control the current temperature of the vertical plate, so that the water vapor condensation effect in the water vapor can be improved, the temperature of the water vapor can be rapidly reduced in hot summer, and the temperature value of the blown dry vapor can be regulated.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present utility model is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
