In the embodiment of the present invention, the winding mechanism 2 further includes: a rotatable idler, and a conveying mesh 26 sleeved over the idler. As shown in fig. 2, the carrier roller is disposed between the joint coating belt shaft 22 and the adsorption roller 23, and includes: a first idler 25A adjacent the suction roller 23 and a second idler 25B adjacent the patch belt shaft 22. The first carrier roller 25A and the second carrier roller 25B are used for tensioning and driving the conveying net 26; the conveying net 26 is used for receiving the joint tape separated from the joint tape shaft 22 and conveying the joint tape to the adsorption roller 23.
Wherein, the conveying net 26 is sheathed on the first carrier roller 25A and the second carrier roller 25B in a caterpillar track shape. The conveying net 26 can be moved while the first idlers 25A and the second idlers 25B are rotated.
In use, the patch tape off the patch tape shaft 22 is placed on the transport web 26. The conveying net 26 is driven to convey through the first carrier roller 25A and the second carrier roller 25B, and then the joint coating belt is conveyed to the adsorption roller 23 from the joint coating belt shaft 22, so that the joint coating belt is wound on the pipeline through the rotation of the adsorption roller 23.
Specifically, in order to ensure that the conveying net 26 smoothly conveys the patch tape, the end of the conveying net 26 close to the patch tape shaft 22 is higher than the end of the conveying net 26 close to the adsorption roller 23.
Further, in order to prevent the patch tape from being separated from the conveyor belt when the patch device is rotated on the duct, a press roller assembly 29 for pressing the patch tape on the conveyor net 26 is further provided above the patch tape shaft 22. Specifically, referring to fig. 2, the roll assembly includes: a platen roller shaft 291 detachably connected to the frame 21 and rotatable about its own axis; an eccentric 292 fixed to the platen roller shaft 291; a pinch roller holder 293 abutting against the lower portion of the eccentric wheel 292; and a pressure roller 294 fixed to the pressure roller bracket 293.
With regard to the structure of the eccentric 292 fixed to the platen roller shaft 291, it is understood that the distance from the edge of the eccentric 292 to the platen roller shaft 291 varies along the axial direction of the eccentric 292. And because the press roller shaft 291 can rotate by taking the axis of the press roller shaft 291 as an axis, the press roller shaft 291 can drive the eccentric wheel 292 to rotate synchronously. Further, since the lower portion of the eccentric 292 abuts against the pinch roller holder 293, when the portion of the eccentric 292, which is farther from the pinch roller shaft 291, abuts against the pinch roller holder 293, the eccentric 292 exerts a pressing action on the pinch roller holder 293. The pressure roller 294 is further pressed downward so that the pressure roller 294 is close to the conveying wire 26, thus pressing the patch tape on the conveying wire 26.
Further, a mounting hole for passing the platen shaft 291 is provided on the side plate. In other words, the platen roller shaft 291 rides between the two side plates, and the platen roller shaft 291 is rotatable in the mounting hole.
Regarding the driving manner of the adsorption roller 23, the first carrier roller 25A and the second carrier roller 25B, in the embodiment of the present invention, the winding mechanism 2 further includes a first driving component for driving the carrier rollers and the adsorption roller 23 to rotate.
Referring specifically to fig. 3 in conjunction with fig. 2, a first sprocket 27A is provided at an end of the first idler 25A, a second sprocket 27B is provided at an end of the second idler 25B, and a third sprocket is provided at an end of the adsorption roller 23. And the first driving assembly includes: a motor, a fourth sprocket 27C, a first chain 28A and a second chain 28B. Wherein, the motor is arranged below the conveying net 26, and the fourth chain wheel 27C is connected with the output end of the motor; the first chain 28A connects the first sprocket 27A, the second sprocket 27B and the fourth sprocket 27C at the same time; the second chain 28B connects the fourth sprocket 27C and the third sprocket simultaneously. Wherein the fourth sprocket 27C is a double sprocket.
When the roller carrier roller device is used, the motor drives the fourth chain wheel 27C to rotate, and the fourth chain wheel 27C drives the first chain wheel 27A and the second chain wheel 27B through the first chain 28A, so as to drive the first carrier roller 25A and the second carrier roller 25B to rotate. Meanwhile, the fourth sprocket 27C drives the third sprocket to rotate through the second chain 28B, and further drives the adsorption roller 23 to rotate.
To secure the first chain 28A in a tensioned state, a tension pulley assembly is connected to the first idler 25A. The first idler 25A can be pulled by the idler assembly, thereby placing the first chain 28A in tension. In addition, the conveying net 26 can be ensured to be in a tensioning state by pulling the first carrier roller 25A, and effective conveying of the joint strip is realized.
The invention is not particularly limited with respect to the specific form of the tension assembly. For example, a roller shaft seat 251 is provided at an end of the first roller 25A, and a third slide groove adapted to the roller shaft seat 251 is provided on a side plate of the frame 21. The first idler 25A is connected to an idler shaft seat 251 through a bearing, and a tension rod 252 is screwed to the idler shaft seat 251. The tension rod 252 is only rotatable but cannot move axially along itself. Thus, when the tension rod 252 is rotated, the idler shaft seat 251, which is threadedly coupled to the tension rod 252, can move along the third slide slot, thereby tensioning the first chain 28A and the conveying net 26 when moving away from the second tension rod 25B.
Further, with regard to the structure of the second heating assembly 24, see fig. 2 and 3 in particular. The second heating assembly 24 includes: an infrared lamp holder 241; a plurality of infrared lamps 242 fixed to the infrared lamp holder 241; and an infrared reflection plate 243 disposed above the infrared lamp tube 242. The repaired mouth belt is heated through the infrared lamp tube 242, so that the glue layer on the repaired mouth belt is melted and then is pasted on the pipeline, the heat loss is avoided through the infrared reflection plate 243, the heat of the infrared lamp tube 242 is fully utilized, and the repaired mouth belt is effectively heated.
The infrared reflection plate 24 is inserted into a side plate of the rack 21, so that a relatively closed space is formed by the infrared reflection plate 24 and the side plate, and heat dissipation of the infrared lamp tube 242 is further avoided. Especially under the working environment of strong wind and low temperature, the heating stability can be more prominent, and the uniform heating and shrinkage of the joint strip can be ensured.
In the embodiment of the present invention, the adsorption roller 23 is a vacuum adsorption roller, and the adsorption of the patch tape is preferably realized by the vacuum adsorption roller, so that the patch tape is smoothly adhered to the pipeline. Regarding the structure of the adsorption roller 23, it is preferable that the adsorption roller 23 includes a silicone rubber layer provided on the surface of the roller. The silica gel material is softer, has certain deformability. Because there is unevenness's the condition in the place that needs the joint coating on the pipeline, consequently set up the silica gel layer at the roller surface of adsorption roll 23 and can compensate the adsorption roll 23 outer wall to the distance fluctuation between the pipeline outer wall for the joint coating area laminating is on the pipeline outer wall.
Regarding the structure of the heating mechanism 3, the first heating member 31 is a medium frequency heating device provided with a coil. Compared with the mode of heating by open fire in the prior art, when the intermediate frequency heating device is used for heating the outer wall of the pipeline, the influence of the environment on the heat source of the heating device is avoided, and therefore, the effective heating of the outer wall of the pipeline can still be guaranteed even in strong wind and low-temperature weather.
The heating mechanism 3 further includes: a road wheel 32 fixed on the second arc-shaped bracket 12 and a second driving component 33 used for driving the bracket 1 to rotate on the pipeline. Through second drive assembly 33 drive overall arrangement along pipeline circumferential direction, and walking wheel 32 can effectively reduce the frictional resistance when this repaired mouth device rotates for the device is more convenient.
When the joint coating device provided by the embodiment of the invention is used, the second driving component 33 is firstly started to drive the joint coating device to rotate on a pipeline, and the outer wall of the pipeline is preheated through the first heating component in the rotating process. And then, a motor in the second driving assembly is started, so that the conveying belt 25 and the adsorption roller 23 start to rotate, and the joint tape on the joint tape shaft 22 is wound and adhered on the outer wall of the pipeline after being heated by the second heating assembly 24. And then, continuously rotating the joint coating device, and heating the joint coating belt again through the first heating assembly to shrink the joint coating belt, thereby finishing joint coating operation.
