Referring to fig. 1 and fig. 2 together, a description will be given of a thermal cycle energy-saving drying tunnel for a polishing machine according to an embodiment of the present utility model. The heat cycle energy-saving drying tunnel for the glazing machine comprises a blower 100, an air inlet chamber 200, an air suction chamber 300, a conveying belt 500 and a heating element 700.
Wherein the blower 100 includes an air inlet duct 101 and an air outlet duct 102, wherein the air inlet duct 101 is for discharging flowing air and the air suction duct is for sucking air. The blower 100 in this embodiment may be a blower 100 commonly used in the art. The air inlet chamber 200 is connected to the discharge end of the blower 100 through the air outlet pipe 102, and can be used for receiving the flowing air discharged from the blower 100, and the flowing air can be homogenized in the air inlet chamber 200, so that the air is more uniform in the whole space. The shape of the air intake chamber 200 in this embodiment is not limited, and may be selected from shapes commonly used in the art. The air inlet chamber 200 has an air outlet for discharging flowing air in the air inlet chamber 200, an air inlet of the air suction chamber 300 is close to an air outlet of the air inlet chamber 200, the air suction chamber 300 is communicated with a suction end of the blower 100 through the air inlet pipe 101, and a paper channel 400 is formed between the air inlet chamber 200 and the air suction chamber 300; the transport belt 500 is disposed within the paper path 400 for transporting paper through the paper path 400. Of course, the paper in this embodiment may be replaced with other printed matter requiring glazing. The heating member 700 is disposed in the paper path 400 between the conveying belt 500 and the air inlet plenum 200 for heating the flowing air discharged from the air outlet of the air inlet plenum 200.
According to the above-mentioned structure of the heat cycle energy-saving drying tunnel for a polishing machine, it can be known that when the heat cycle energy-saving drying tunnel for a polishing machine provided in this embodiment is used, the blower 100 is used to introduce flowing air into the air inlet chamber 200, the flowing air is homogenized in the air inlet chamber 200 and discharged from the air outlet of the air inlet chamber 200 into the paper channel 400, and in the paper channel 400, the flowing air is heated by the heating element 700, so that the polishing oil on the paper after curing can be dried. The remaining high-temperature flowing air after drying the paper can enter the air suction chamber 300 through the air inlet of the air suction chamber 300, and then returns to the blower 100 through the air inlet pipe 101 communicated with the air suction chamber 300. Therefore, the air re-entering the blower 100 actually has high-temperature gas with a considerable temperature, and can participate in the next drying operation after being re-discharged into the air inlet chamber 200 through the blower 100, so that the heat energy of the high-temperature gas is greatly prevented from flowing away, and the energy-saving and emission-reducing technical effect is far better than that of the prior art.
Referring to fig. 1 and 2, the air intake chamber 200 includes an air filling top cover 201 and a punching grid plate 202. Wherein, the air filling top cover 201 is provided with through holes for communicating the air inlet chamber 200 and the air outlet pipe 102, the punching grid plate 202 is provided with a plurality of air equalizing holes 221 which are uniformly distributed along the extending direction of the paper channel 400, and the air equalizing holes 221 are air outlets of the air inlet chamber 200. By the above arrangement of the air equalizing port structure, the uniformity of the flowing air discharged from the air intake chamber 200 is further increased, effectively avoiding the problem of non-uniformity of heat in the paper passage 400. It will be appreciated that the specific shape of the air equalizing hole 221 in this embodiment is not limited, and a circular, square, rectangular or other polygonal structure commonly used in the art may be used. For convenience of explanation, in this embodiment, the air equalizing hole 221 is exemplified as a circular hole.
Referring to fig. 1 and 2, in some embodiments, at least two through holes are disposed on the top cover 201 along the extending direction of the paper channel 400, and both of the through holes are communicated with the air outlet pipe 102. According to this structure, the heat cycle energy-saving drying tunnel for a glazing machine provided in this embodiment can further increase the uniformity of air in the air intake chamber 200.

Referring to fig. 1 and fig. 2 together, in another embodiment of the present utility model, the heat cycle energy-saving drying tunnel for a glazing machine further includes a plurality of triangular air deflectors 600; the triangular air deflector 600 is disposed in the paper path 400 and is located between the conveyor belt 500 and the air inlet plenum 200; the plurality of triangular air deflectors 600 are sequentially arranged along the extending direction of the paper path 400, and one side of each triangular air deflector 600 faces the conveying belt 500, and a gap is formed between two adjacent triangular air deflectors 600 for the flowing air discharged from the air outlet of the air inlet chamber 200 to pass through, and the flow velocity of the hot air is increased, so that the hot air can be directly sprayed on the paper to be dried and solidified, and the drying and solidifying speed is increased. According to the structure of the triangular air deflector 600 provided in the present embodiment, the uniformity of the flowing air from the air inlet chamber 200 is further increased, and the uniformity of the hot air blown onto the paper can be well ensured.
Referring to fig. 1 and 2, in addition to the above embodiments, in some embodiments, the heating element 700 is specifically configured as a carbon fiber heating tube. The carbon fiber heating pipe has the technical effects of quick heating, high efficiency and high temperature resistance. In the present embodiment, the heating members 700 are provided in plurality and each heating member 700 is provided between two adjacent triangular air deflectors 600. The flowing air in the paper path 400 can be uniformly heated. The number of heating elements 700 may be the same as or different from the number of triangular air deflectors 600. For example, two heating elements 700 may be disposed between two adjacent triangular air deflectors 600. In the actual production process, the device can be flexibly selected according to the needs and is not repeated.
Referring to fig. 1 and fig. 2 together, in some embodiments, the thermal cycle energy-saving drying tunnel for a polishing machine further includes a temperature sensor 800, where the temperature sensor 800 is used to detect the temperature of the air heated by the heating element 700. In this embodiment, by providing the temperature sensor 800, the temperature of the flowing air in the paper path 400 can be easily obtained, and the heating power of the heating member 700 can be adjusted. For example, at the time of starting the heat cycle energy saving drying tunnel for a glosser, since the flowing air exhausted from the air inlet chamber 200 does not have a high temperature, the heating member 700 can be maintained to operate at a high power to rapidly heat the flowing air temperature in the paper path 400. After the flowing air circulates for many times, the temperature of the structures such as the air inlet chamber 200, the paper channel 400, the air suction chamber 300 and the like rises, the flowing air always keeps a certain temperature, so that the running power of the heating element 700 can be adjusted and reduced, the effects of saving energy and reducing emission are further achieved, the overhigh temperature in the paper channel 400 can be avoided, and the temperature of the flowing air in the paper channel 400 always keeps within a reasonable range. In some embodiments, the temperature sensor 800 and the heating member 700 may also be connected to an automatic control system, which may allow for more accurate control of the temperature of the flowing air in the paper path 400, and may also provide for better energy savings.
Referring to fig. 1 and fig. 2 together, in another embodiment of the present utility model, the air inlet pipe 101 and the air outlet pipe 102 are made of high temperature resistant materials, so that faults of the air inlet pipe 101 and the air inlet pipe 101 can be effectively avoided, and the service life of the heat cycle energy-saving drying tunnel for a glazing machine provided by the embodiment is effectively prolonged.
