[0002] Enclosures are widely used in pipeline insulation, equipment protection and other fields. The core process in their processing is seam joining, which involves joining and pressing the edges of the enclosure blank together to form a ring or cylindrical enclosure with a specific diameter and length.

[0003] The current webbing seam joining process requires manual feeding of the webbing blank to the joining station, and after joining, it needs to be manually transferred to the cutting station. The connection between processes relies on manpower, resulting in low production efficiency and high labor costs. Manual feeding is prone to misalignment of the edges of the webbing blank, which can easily lead to quality problems such as weak joining, wrinkling or cracking of the edges, affecting the stability of the webbing in subsequent use. Moreover, existing equipment is mostly designed for single-specification webbing. When processing webbing of different specifications, a large number of parts need to be disassembled and replaced, resulting in a long adjustment cycle. This cannot meet the production needs of multiple varieties and small batches. Therefore, it is necessary to design a fully automatic webbing seam joining machine to solve the above problems.

[0018] Specifically, a first motor 12 is fixedly connected to the upper side of the front end face of the fixed support plate 2 at the front end. The output shaft of the first motor 12 is fixedly connected to the upper side of the wrapping roller 3. The rear ends of the two wrapping rollers 3 are fixedly connected to pulley sets 13. The front ends of the inner transmission wheels of the two pulley sets 13 are fixedly connected to gear sets 14. The pulley sets 13 and gear sets 14 are rotatably connected to the rear fixed support plate 2. By driving the first motor 12 to rotate, the upper wrapping roller 3 can rotate, thereby enabling the rear pulley sets 13 and gear sets 14 to drive the lower wrapping roller 3 to rotate in the opposite direction at the same time, so that the two wrapping belts can be output to the left at the same time.

[0019] Specifically, a lifting frame 15 is slidably connected to the upper wall of the feeding frame 4, and an adjusting screw 16 is rotatably connected to the middle position of the lifting frame 15. The adjusting screw 16 is screwed to the feeding frame 4, and a turntable 17 is fixedly connected to the upper end of the adjusting screw 16. The lifting frame 15 is rotatably connected to the driven pressure roller 6. By driving the turntable 17 to rotate, the adjusting screw 16 can drive the lifting frame 15 and the driven pressure roller 6 to move up and down, thereby enabling the driven pressure roller 6 to squeeze the shroud of different thicknesses.

[0020] Specifically, a second motor 18 is fixedly connected to the lower front end of the feeding frame 4. The output shaft of the second motor 18 is fixedly connected to the conveying support roller 5.

The blanking conveyor belt 28 can automatically blank the closed webbing. The activation and extension of the hydraulic cylinder 25 can drive the knife holder 26 to move the cutting blade 27 up and down, thereby cutting the closed webbing according to the required cutting length.

[0024] Working Principle: This utility model is a fully automatic webbing seam sealing machine. When seaming webbing, two webbing strips are first wound around the outside of the webbing roller 3. The upper webbing roller 3 is rotated by driving the first motor 12, which in turn drives the lower webbing roller 3 to rotate in the opposite direction via the rear pulley set 13 and gear set 14. This allows both webbing strips to be output to the left simultaneously. The conveying support roller 5 provides support for the webbing, while the adjusting screw 16 is adjusted by driving the turntable 17. The lifting frame 15 and the driven pressure roller 6 move up and down, allowing the driven pressure roller 6 to compress the sheaths of different thicknesses. Combined with the drive of the second motor 18, the conveying support roller 5 and the driven pressure roller 6 stably convey the two pressed sheaths. The two sheaths, which are in contact with each other, are conveyed to the upper end of the guide support roller 19. The electric push rod 20 is driven to extend and retract, allowing the positioning plate 8 to move back and forth. This enables the positioning plate 8 to correct and position the front and rear sides of the sheaths, ensuring proper seam finishing in subsequent processes. The process ensures high-quality workmanship. After the webbing is conveyed above the upper heating pressing roller 10, the third motor 21 drives the threaded shaft 22 to move the lifting sleeve 23 and the connecting telescopic rod 24 up and down, thereby allowing the upper heating pressing roller 10 to move up and down accordingly. This not only controls the pressing force but also allows for adaptive adjustment based on the thickness of the webbing, facilitating the joining of webbing of different specifications. Furthermore, the lower heating pressing roller 9 and the upper heating pressing roller 10 can heat and join the edges of the two webbing strips, and also improve the quality of the webbing. The belt undergoes continuous seam joining processing, and the joined portion is conveyed to the unloading conveyor belt 28. The unloading conveyor belt 28 can automatically unload the joined belt. The hydraulic cylinder 25 activates and extends, causing the cutter holder 26 to drive the cutting blade 27 to move up and down, thereby cutting the joined belt according to the required cutting length. During this process, only the two belts need to be manually moved to the seam position. Subsequently, automatic feeding, seam joining, cutting, and unloading can be achieved, greatly improving the efficiency of the belt seam joining process.
