Description

Technical Field

[0001] This utility model relates to the technical field of pipe processing, and in particular to a manual composite duct straight pipe slicing machine. Background Technology

[0002] Composite air ducts are ventilation ducts made of composite materials consisting of two layers of thin metal sheets (such as galvanized steel sheets or aluminum foil) sandwiched with insulation materials (such as glass wool or polyurethane foam).

[0003] Existing composite duct straight pipe slicing machines, such as the utility model patent with application number 202422128602.7, disclose a thickness-adjustable rubber and plastic insulation pipe slicing machine. Its main structure includes a base and a first fixed frame. The first fixed frame is fixedly installed on the top surface of the base, and the slicing mechanism is fixedly installed on the top surface of the first fixed frame and the base. In use, the screw is rotated by rotating the adjusting wheel, which causes the limiting baffle connected to the screw to move, thereby ensuring that the rubber and plastic insulation pipe slicing thickness is adjusted when it comes into contact with the limiting baffle.

[0004] However, existing slicers are not convenient for controlling slice thickness. Each slice requires repeated manual measurement, which is very troublesome. Moreover, the straight tube is prone to deviation during forward feeding, which affects the cutting effect. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a manual composite duct straight pipe slicing machine that can not only clamp and position both sides of the straight pipe to prevent it from deviating during forward conveying, but also facilitate the adjustment of the cutting thickness of the straight pipe, saving the staff the trouble of repeated measurement.

[0006] This utility model discloses a manual composite duct straight pipe slicing machine, including a support mechanism; it also includes a protective mechanism, an adjustment mechanism, two sets of clamping mechanisms, a limiting mechanism, and a cutting mechanism. The protective mechanism is installed on the support mechanism to prevent waste debris from splashing. The adjustment mechanism is installed on the protective mechanism to adjust the distance between the two sets of clamping mechanisms. Both sets of clamping mechanisms are installed on the adjustment mechanism and convey the straight pipe forward. The limiting mechanism is installed on the support mechanism to position the top of the straight pipe. The cutting mechanism is installed on the protective mechanism to cut the straight pipe. When the straight pipe is conveyed to the support mechanism, the adjustment mechanism adjusts the distance between the two sets of clamping mechanisms to clamp both sides of the straight pipe, so that the straight pipe is in the middle position of the support mechanism. The position of the limiting mechanism is adjusted as needed to limit the front end of the straight pipe. The two sets of clamping mechanisms convey the straight pipe forward. When the straight pipe reaches the limiting mechanism, the conveying stops. The operator operates the cutting mechanism to cut the straight pipe. After the cutting is completed, the limiting mechanism is erected to facilitate the support mechanism to drive the straight pipe slices for feeding.
