Description

Technical Field

[0001] This utility model relates to the field of tube making machine technology, specifically a cutting device for a corrugated tube making machine. Background Technology

[0002] Traditional corrugated pipe making machines require manual observation of the produced corrugated pipe length before manually moving the cutting disc of the cutting machine to cut the produced corrugated pipe. This method not only fails to guarantee the cutting length of the product, but also increases the labor intensity of the workers.

[0003] Existing technology, patent document CN215149467U, provides a universal online cutting device for corrugated pipe making machines. The device includes a pipe making machine body. An arc-shaped plate is fixedly connected to one side and the output end of the machine body. Horizontal plates are fixedly connected to the left and right sides of the arc-shaped plate. A vertical plate is fixedly connected to the upper surface of the horizontal plate. A horizontal plate perpendicular to the vertical plate is fixedly connected to the upper end of one side of the vertical plate. An electric telescopic rod is fixedly connected to the upper surface of the horizontal plate. The output end of the electric telescopic rod passes through and slides into the interior of the horizontal plate. A rectangular plate is fixedly connected to the output end of the electric telescopic rod. This device can accurately cut corrugated pipes, ensuring consistent cutting lengths. Simultaneously, automatic cutting reduces the labor intensity of workers. The length measuring instrument accurately measures the product length, and the electric telescopic rod controls the lifting and lowering of the cutting disc, facilitating cutting and making it convenient to use.

[0004] Although the device has many beneficial effects, the following problems still exist: When the bellows moves on the arc plate, the bellows will shake due to the cutting of the cutting disc, causing the bellows to shift in position and affecting the quality of the cut product.

[0005] Secondly, when the cutting disc of the device cuts the bellows, the vertical extension and retraction will cause the bellows to shake vertically, affecting the positioning of the bellows. Utility Model Content

[0047] The buffer mechanism 200 is installed at the connection between the vertical rod 1 and the arc frame 3, which can buffer the swaying of the arc frame 3.

[0048] It is worth noting that, specifically, for clamping purposes, the clamping mechanism 100 includes: a slide groove a101 formed on the side wall of the arc-shaped frame 3;

[0049] The slide groove b102 is opened at the top of the arc frame 3. Two clamping plates 103 are slidably connected in the slide groove b102. Sliding plates 104 are fixed on the side walls of the two clamping plates 103. The two sliding plates 104 are slidably connected in the slide groove a101.

[0063] 2: The device will shake during operation. The arc frame 3 moves away from the vertical rod 1, the pull rod 202 moves away from the groove b203, the damping spring 204 is stretched, and the limiting plate 206 at the other end of the pull rod 202 and the baffle 205 at the opening of the groove b203 limit each other to prevent the arc frame 3 from moving too far away from the vertical rod 1, which would affect the cutting of the corrugated pipe.
