Description

Technical Field

[0001] The utility model relates to the technical field of coating machine drying room transmission, in particular to a heating device for a powder dot coating machine. Background Art

[0002] In the field of clothing or interlining technology, sometimes both sides of the base fabric are powder-coated using a coating machine.

[0003] The existing anti-sticking transmission heating device for the drying room of a double-point coating machine (authorization announcement number: CN206046431U) has a lower heating plate connected between the driving roller and the driven roller in the drying room. The above-mentioned transmission flat belt rests on the lower heating plate. Driven by the transmission flat belt, the double-point coated clothing material is heated by the lower heating plate, which ensures uniform heating and is particularly energy-efficient. Because the outer side of the transmission flat belt has an anti-sticking layer, which is a polytetrafluoroethylene coating, the double-point coated clothing material will not stick to the transmission flat belt during the heating process, thereby ensuring the quality of the double-point coated clothing material.

[0004] However, this device has some shortcomings in actual use: the top side of the conveyor belt is heated by the upper heating element. When the conveyor belt conveys the coated clothing material, the coated clothing material will block the heat of the upper heating element on the conveyor belt, which will cause uneven heat distribution on the inner and outer walls of the conveyor belt, and the coated clothing material is likely to adhere to the conveyor belt, affecting the conveyance of the coated clothing material by the conveyor belt; therefore, we propose a heating device for a powder dot coating machine to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a heating device for a powder dot coating machine to solve the above problems.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] Preferably, the outer surface of the conveyor belt is provided with an anti-sticking layer, and the anti-sticking layer is a polytetrafluoroethylene coating; during the heating process of the conveyor belt, the adhesion of the powder-dot coated clothing material to the conveyor belt is reduced, thereby ensuring the normal conveying operation of the powder-dot coated clothing material on the conveyor belt.

[0009] Preferably, the transmission mechanism includes a pulley and a belt body, pulleys are fixedly mounted on the two active rods, and the same belt body is sleeved between the two pulleys; through the transmission mechanism, the two pulleys are indirectly and synchronously driven to rotate, thereby realizing reciprocating transmission of the conveyor belt in the drying box.

[0010] Preferably, the driven mechanism includes a driven rod and a driven gear, one end of each of the two auxiliary rollers is fixedly mounted with one end of the driven rod, the other ends of the two driven rods respectively pass through the outside of the corresponding side plates and are fixedly mounted with driven gears, and the two driven gears are respectively engaged with the corresponding driving gears; through the driven mechanism, the two sets of driven rods and auxiliary rollers are indirectly and synchronously driven to rotate.

[0011] Preferably, the two driven gears are respectively located outside the corresponding driving gears, and the pulleys and the driven gears are arranged in a staggered manner; this facilitates the two driven gears to be respectively located at the corresponding driving gears and meshed with each other.

[0012] Preferably, the conveying drive mechanism includes a frame and a motor, the frame is fixedly mounted on the corresponding side panel, the motor is fixedly mounted on one side of the frame, and the output shaft of the motor is fixedly mounted on the corresponding active rod; by starting the motor, the pulley and driving gear on the corresponding active rod are driven to rotate.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The heating device of the powder dot coating machine is provided with a first infrared heating tube in two conveying rollers and a second infrared heating tube in two auxiliary rollers. Through the cooperation of a conveying drive mechanism, a transmission mechanism and a driven mechanism, the two sets of heated conveying rollers heat the inner side wall of the conveyor belt, and the two sets of heated auxiliary rollers heat the outer side wall of the conveyor belt, thereby achieving uniform heating of the entire conveyor belt. During the heating process of the conveyor belt, the adhesion of the powder dot coating clothing material to the conveyor belt is reduced, thereby ensuring the normal conveying operation of the powder dot coating clothing material on the conveyor belt.
