Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation belt production, in particular to a card back-blowing device in a screening pot. Background Art

[0002] Drip irrigation belt uses plastic pipes to deliver water to the roots of crops through holes or drippers on capillary tubes with a diameter of about 10 mm for local irrigation. It drips water evenly and slowly into the soil near the roots of crops drop by drop through drippers or drip irrigation belts with very small outflow holes.

[0003] During the production process of the drip irrigation tape, the patch needs to be transported to the screening pot first, and the screening effect of the screening pot will transport the patch to the rubber extruder in the correct direction, so that the patch can be properly bonded to the inside of the drip irrigation tape extruded by the extruder.

[0004] When the patch is rotated and screened in the screening pot, if the patch enters the conveyor track for transportation with the reverse side facing upward, the drip irrigation tape produced after working with the rubber extruder cannot normally realize the function of the dripper, which is easy to produce defective products. Utility Model Content

[0005] In order to overcome the above defects existing in the prior art, the utility model provides a card back-flushing device in a screening pot.

[0006] The utility model adopts the following technical solution to solve the technical problem: a card back-blowing device in a screening pot, comprising a base, a screening pot is arranged above the base, the screening pot is used for screening patches, the screening pot is connected to a conveying track outside, a conveying trough is arranged on the conveying track, the conveying trough is used for conveying patches to an extruder, a sheet blowing mechanism is arranged outside the conveying track, and the sheet blowing mechanism is located in the screening pot.

[0007] Furthermore, the sheet blowing mechanism includes a base, which is arranged inside the pedestal, and a plurality of telescopic devices are fixedly installed on the top of the base, and a sliding block is fixedly installed on the telescopic end of the telescopic device, and the sliding block is movably installed on the conveying track.

[0008] Furthermore, the upper and lower widths of the sliding block are greater than the upper and lower widths of the conveying track.

[0009] Furthermore, a groove corresponding to the conveying groove is arranged above the sliding stopper.

[0010] Furthermore, an air outlet pipe is provided inside the sliding stopper, and the air outlet pipe is externally connected to an air blowing device.

[0011] Furthermore, a high-speed camera is arranged above the sliding stopper, and the high-speed camera is used to detect the front and back of the patch.

[0012] The beneficial effect of the utility model is that the positive and negative positions of the patch are detected by a high-speed camera. When the patch at the detection position is reversed, the telescopic device is started to move the sliding block upward. At this time, the patch is lifted by the sliding block, and the sliding block can block the subsequent patches from continuing to be transported. At the same time, the blowing device is started to blow air into the air outlet pipe to blow the patch back into the screening pot. Then the sliding block falls and the device continues to operate.
