Description

Technical Field

[0001] This utility model relates to the field of spiral duct machine technology, specifically a spiral duct machine with high stability. Background Technology

[0002] A spiral duct winding machine is a device used to wind wide strip materials into spiral ducts. Its working principle involves a drive and transmission mechanism that feeds the raw material into a winding machine. The winding machine bends both sides of the strip material upwards and downwards respectively. Then, guided by a ring-shaped steel belt, the downward-curved edges interlock with the upward-curved edges. Finally, pressure is applied to the interlocked edges by the relatively rolling winding wheels, thus forming a spiral duct.

[0003] In existing technologies, the cutting process after spiral duct forming often becomes a key factor affecting processing quality and efficiency. When cutting spiral ducts with existing cutting equipment, the vibration of the cutting machine itself and the interaction between the cutting machine and the spiral duct during the cutting process can easily cause the duct to shift or vibrate, thus affecting cutting accuracy and the stability of the finished product. To solve this problem, operators usually need to manually press down on the spiral duct from one side of the cutting machine to enhance its stability during the cutting process.

[0004] However, while manual pressing provides some stability during spiral duct cutting, it has several drawbacks. First, it poses significant safety hazards, as operators are in close proximity to the high-speed cutting equipment, and the spiral duct may move unexpectedly due to vibration or misalignment, increasing the risk of injury. Second, it is inefficient; manual pressing limits cutting speed and production efficiency, especially in large-scale production. Furthermore, consistent quality is difficult to guarantee; differences in pressing pressure, position, and habits among different operators can lead to uneven cut surfaces or duct deformation.

[0024] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a highly stable spiral duct machine, comprising: an auxiliary pressing mechanism, which is used to assist in squeezing and fixing the spiral duct; the auxiliary pressing mechanism includes symmetrically arranged vertical plates 1; a threaded rod 2 is rotatably installed between the tops of the two vertical plates 1; the vertical plates 1 provide stable support for the threaded rod 2; movable blocks 3 are symmetrically threaded onto the threaded rod 2; the two movable blocks 3 can move in opposite directions or towards each other in the axial direction of the threaded rod 2; the lower side of the movable blocks 3 is rotatably connected to the upper surface of the pressure plate 4; the lower surface of the pressure plate 4 is fixedly connected to the upper surface of the pressure block 6 through a buffer 5; the buffer 5 is used for buffering to avoid damaging the spiral duct; a silicone pad 7 is fixedly connected to the lower surface of the pressure block 6; the silicone pad 7 further fits against the spiral duct, thereby abutting the spiral duct; support rollers 8 are rotatably arranged on both sides of the bottom of the vertical plates 1; the support rollers 8 facilitate the outward transmission of the processed spiral duct.

[0026] When the drive and transmission mechanisms of the spiral duct machine feed the raw material into the biting machine, the biting machine curls the two sides of the coiled material upwards and downwards respectively. Then, guided by the annular steel belt, the downward-curled edge and the upward-curled edge interlock. Finally, the biting wheels, which roll relative to each other, apply pressure to the interlocked curled edges, thus forming a spiral duct. The spiral duct is transported to the outside under the support of the support roller 8. When the processing length reaches the required length, the threaded rod 2 is controlled to rotate, which causes the threaded rod 2 to drive the threaded moving block 3 on it to move towards each other. The moving block 3 is connected to the pressure plate 4 at its bottom, which causes the pressure plate 4 to move downwards after being limited by the vertical plate 1. Under the connection of the buffer 5, the pressure plate 4 drives the pressure block 6 to move synchronously until the silicone pad 7 is tightly abutted against the outer ring surface of the spiral duct. At this time, the threaded rod 2 stops rotating, and then the spiral duct is pressed and fixed. This avoids the need for manual pressing to cut the spiral duct, reduces safety hazards, and improves processing efficiency.

[0027] Example 2: Based on Example 1, one end of the threaded rod 2 is fixedly connected to the output end of the upper motor 9. The upper motor 9 is electrically connected to an external terminal control device. The upper motor 9 is fixedly connected to one side of one of the vertical plates 1. The threaded rod 2 has two threads with opposite directions of rotation. Limiting blocks 10 are fixedly connected to the upper surface of the moving block 3. A limiting frame 11 is fixedly connected between the tops of the two vertical plates 1. The limiting frame 11 and the limiting block 10 are slidably connected, thereby improving the stability of the movement of the limiting block 10. Both ends of the pressure plate 4 are slidably connected to the vertical plate 1. Both sides of the moving block 3 are rotatably connected to one end of the connecting rod 12 through a pin 13. The other end of the connecting rod 12 is rotatably connected to the top of the connecting seat 14 through a pin 13. The bottom of the connecting seat 14 is fixedly connected to the pressure plate 4.

[0028] Before cutting the spiral duct, the upper motor 9 is controlled by an external control device to start the upper motor 9, which in turn drives the threaded rod 2 to move. The threaded rod 2 rotates under the support and limit of the vertical plate 1. Since the threaded rod 2 has two threads with opposite directions of rotation, it drives the moving blocks 3 with symmetrical threaded sleeves on it to move in opposite directions. The moving blocks 3, through the rotational connection between the connecting rod 12, the pin 13, and the connecting seat 14, drive the pressure plate 4 to move downward. The pressure plate 4, under the connection of the buffer 5, drives the pressure block 6 to move synchronously until the silicone pad 7 is tightly abutted against the outer ring surface of the spiral duct. At this time, the spiral duct is fixed, which facilitates subsequent cutting. After cutting, the pressure block 6 can be moved away from the spiral duct by controlling the upper motor 9 to rotate in the opposite direction. At the same time, by controlling the rotation of the threaded rod 2, the moving distance of the pressure block 6 can also be adjusted, which facilitates the cutting of spiral ducts of different diameters.

[0029] Example 3: Based on Example 2, the two ends of the support roller 8 are rotatably sleeved on the support plate 15, and the support plate 15 supports the support roller 8, thereby facilitating the rotation of the support roller 8. A rotating roller 16 is provided between the two support plates 15, and the two sides of the rotating roller 16 are rotatably sleeved in the fixed plate 17, which supports the rotating roller 16. One end of the rotating roller 16 is fixedly connected to the output end of the lower motor 18, and the lower motor 18 is electrically connected to an external terminal control device. The lower motor 18 is fixedly installed on one of the fixed plates 17. A cutting device 19 is provided at the other end of the rotating roller 16, and the cutting device 19 is electrically connected to the external terminal control device. A multi-stage electric push rod 20 is provided directly below the support roller 8, and the multi-stage electric push rod 20 is electrically connected to the external terminal control device. An anti-slip pad 21 is fixedly connected to the output end of the multi-stage electric push rod 20, and the anti-slip pad 21 is adapted to the outer ring surface of the bottom of the support roller 8.

[0030] While the pressure block 6 presses down and fixes the upper side of the spiral duct, the output end of the multi-stage electric push rod 20 is extended upward by controlling it, thereby driving the anti-slip pad 21 to abut against the bottom outer surface of the support roller 8, thus fixing and limiting the support roller 8 to prevent it from rotating, and further improving the stability of the spiral duct during the cutting process. During cutting, the cutting equipment 19 is started by controlling it, and its internal control system will issue a command to start the saw blade and drive the saw blade to move upward according to the preset program. This action makes the rotating saw blade contact the spiral duct below it, and the sharp teeth of the saw blade edge can effectively cut the duct material. In addition, when cutting spiral ducts with larger diameters, since the saw blade cannot cut it completely in one go, the lower motor 18 can be started by controlling it. The lower motor 18 drives the spiral duct to rotate slowly, and then the cutting position is continuously adjusted. With the help of the pressure block 6 and the anti-slip pad 21, the processing of spiral ducts with larger diameters can be completed through multiple cuts.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
