Adjustable spiral duct machine

Abstract

This utility model discloses an adjustable spiral duct machine, belonging to the technical field of spiral duct machines. The adjustable spiral duct machine includes a base frame, with an unwinding machine and a mounting frame installed at both ends of the top of the base frame. A spiral forming main unit and a positioning mechanism are installed on the top of the mounting frame, with the positioning mechanism located between the unwinding machine and the spiral forming main unit. A base is installed on one side of the mounting frame, and a cutting machine is installed on the top of the base. This machine can utilize an adjustment component to freely adjust the position of the positioning rollers on the roller frame, thereby enabling rapid positioning of strips of different specifications. This avoids lateral deviation of the strip, which could cause misalignment during spiral forming and affect the roundness and sealing of the duct.

Description

Technical Field

[0001] This utility model relates to the field of spiral duct machine technology, and more specifically, to an adjustable spiral duct machine. Background Technology

[0002] A spiral duct machine is an automated device used for the continuous rolling of metal spiral ducts. It forms circular or elliptical ducts by spirally coiling and interlocking metal strips (such as galvanized steel sheets and stainless steel). It mainly consists of an uncoiling device, a forming main unit, a seaming mechanism, and a sizing and cutting unit, and is widely used in building ventilation and air conditioning systems.

[0003] Based on the above, the inventors have discovered that: before the metal strip enters the spiral forming machine, it is only centered and positioned by multiple sets of guide rollers. The positioning effect is often poor, and the strip is prone to lateral displacement, causing misalignment in spiral forming, affecting the roundness and sealing of the duct. Furthermore, the guide roller spacing needs to be frequently adjusted manually for strips of different widths, which is inconvenient to use. At the same time, the spiral duct needs to be cut to a fixed length after forming, but the existing equipment does not effectively support the duct during cutting, making it susceptible to displacement due to the impact force of the saw blade, resulting in inaccurate cutting. Therefore, in view of this, the inventors have studied and improved the existing structure to provide an adjustable spiral duct machine, aiming to achieve a more practical purpose. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide an adjustable spiral duct machine. It can use an adjustment component to freely adjust the position of the positioning roller on the roller frame, thereby enabling rapid positioning of strips of different specifications. This avoids lateral deviation of the strip, which can cause misalignment in spiral forming and affect the roundness and sealing of the duct. At the same time, an upper pressing mechanism is added to the unloading frame to press the top of the formed spiral duct, providing effective support and preventing deviation due to the impact of the saw blade, thus improving cutting accuracy.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] An adjustable spiral duct machine includes a base frame, with an unwinding machine and a mounting frame respectively installed at the top two ends of the base frame. A spiral forming host and a positioning mechanism are installed on the top of the mounting frame, with the positioning mechanism located between the unwinding machine and the spiral forming host. A base is installed on one side of the mounting frame, a cutting machine is installed on the top of the base, and a material unloading rack is provided on one side of the base.

[0009] The positioning mechanism includes a bracket fixed to the top of the mounting frame, a positioning seat mounted on the top of the bracket, an adjustment component on the positioning seat, and two symmetrically arranged roller frames on the adjustment component. The top of the roller frames is rotatably connected to a positioning roller.

[0010] Furthermore, the adjustment assembly includes a mounting base fixed at the middle position of the top of the positioning seat and a stepper motor fixed at one end of the positioning seat. A bidirectional lead screw is rotatably connected to the mounting base, and a moving block is threadedly connected to the outer circumference of the bidirectional lead screw. A roller frame is installed on the top of the moving block.

[0011] Furthermore, both movable blocks have threaded holes, and the threads of the two threaded holes have opposite directions.

[0012] Furthermore, guide rods are fixedly connected to both sides of the mounting base, and the moving block is slidably sleeved on the outer periphery of the guide rods.

[0013] Furthermore, an equipment frame is installed on one side of the unloading rack, a limit cylinder is installed on the top of the equipment frame, and an upper pressure mechanism is installed at the output end of the limit cylinder.

[0014] Furthermore, the pressing mechanism includes an upper pressing seat fixed to the output end of the limiting cylinder, and a number of guide rollers are rotatably connected to the bottom of the upper pressing seat.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this scheme, by adjusting the setting of the component, the stepper motor drives the bidirectional lead screw to rotate, so that the two moving blocks drive the positioning roller on the roller frame to adjust the position freely, so as to limit the two sides of the strip and avoid the lateral displacement of the strip causing the spiral forming misalignment, which affects the roundness and sealing of the air duct. At the same time, the positioning roller on the roller frame can be adjusted freely under the action of the adjustment component, so as to realize the position of the strip of different specifications quickly.

[0018] (2) In this solution, by adding an upper pressing mechanism on the unloading rack, when the formed spiral air duct is cut, the limiting cylinder drives the upper pressing mechanism to move down, so that the guide roller at the bottom of the upper pressing seat presses and limits the top of the formed spiral air duct, so that it is effectively supported, avoids deviation due to the impact force of the saw blade, and improves the cutting accuracy.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] Example:

[0037] Please see Figures 1-3 An adjustable spiral duct machine includes a base frame 1. An unwinding machine 2 and a mounting frame 3 are respectively installed at the top two ends of the base frame 1. A spiral forming host 4 and a positioning mechanism 5 are installed on the top of the mounting frame 3, and the positioning mechanism 5 is located between the unwinding machine 2 and the spiral forming host 4. A base 6 is installed on one side of the mounting frame 3. A cutting machine 7 is installed on the top of the base 6. A material unloading rack 8 is provided on one side of the base 6.

[0038] The positioning mechanism 5 includes a bracket 501 fixed to the top of the mounting frame 3. A positioning seat 502 is mounted on the top of the bracket 501. An adjustment component 503 is provided on the positioning seat 502. Two roller frames 504 are symmetrically arranged on the adjustment component 503. A positioning roller 505 is rotatably connected to the top of the roller frame 504.

[0039] See Figure 2 The adjustment assembly 503 includes a mounting base 5031 fixed at the middle position of the top of the positioning base 502 and a stepper motor 5032 fixed at one end of the positioning base 502. A bidirectional lead screw 5033 is rotatably connected to the mounting base 5031. A moving block 5034 is threadedly connected to the outer circumference of the bidirectional lead screw 5033, and a roller frame 504 is installed on the top of the moving block 5034.

[0040] See Figure 2 Both movable blocks 5034 have threaded holes, and the threads of the two threaded holes have opposite directions.

[0041] See Figure 2 Guide rods 9 are fixedly connected to both sides of the mounting base 5031, and the moving block 5034 is slidably sleeved on the outer periphery of the guide rods 9.

[0042] See Figure 3 A device frame 10 is installed on one side of the unloading rack 8. A limit cylinder 11 is installed on the top of the device frame 10. An upper pressing mechanism 12 is installed at the output end of the limit cylinder 11.

[0043] See Figure 3 The pressing mechanism 12 includes an upper pressing seat 1201 fixed to the output end of the limiting cylinder 11, and several guide rollers 1202 are rotatably connected to the bottom of the upper pressing seat 1201.

[0044] In use: One end of the strip on the unwinding machine 2 is passed sequentially through the positioning mechanism 5 and the spiral forming host 4 to make a spiral duct. At this time, the stepper motor 5032 is started to drive the bidirectional lead screw 5033 to rotate, so that the two moving blocks 5034 drive the positioning rollers 505 on the roller frame 504 to freely adjust their positions, so as to limit the two sides of the strip and avoid the strip from shifting laterally, which would cause the spiral forming to be misaligned and affect the roundness and sealing of the duct. After the spiral duct is made, the limiting cylinder 11 is started and drives the upper pressing mechanism 12 to move down, so that the guide roller 1202 at the bottom of the upper pressing seat 1201 presses and limits the top of the formed spiral duct, so that it is effectively supported. At this time, the cutting machine 7 is started to cut the spiral duct. This can avoid the deviation caused by the impact of the saw blade and improve the cutting accuracy.
