Description

Automatic sampling structure for pipe production

Technical Field

The invention relates to the technical field of pipe production, in particular to an automatic sampling structure for pipe production.

Background

The pipe is generally used for conveying fluids such as gas, liquid and the like, and in order to avoid the leakage of the fluids when the pipe is used, the pipe needs to be sampled and detected after production. And tubular product is when production, in order to improve the transport efficiency of tubular product, generally adopt transport structure to transport tubular product, need the manual work to be taken out tubular product when sampling to take off from transport structure, then detect, this just leads to the testing personnel to need be by transport structure constantly for the work load that detects is great, the efficiency of sampling is also lower. In order to avoid the defective products from being packaged and sold, the pipes can be packaged and transported to a warehouse only after sampling and detection are qualified, the sampling efficiency is low, and the packaging efficiency of the pipes is undoubtedly reduced, so that the yield of the pipes is reduced.

In order to achieve the purpose, the invention adopts the following technical scheme: the automatic sampling structure for the pipe production comprises a push rod, a guide unit and a sampling unit, wherein the push rod is opposite to a conveying structure and used for pushing the pipe down from the conveying structure, the guide unit comprises a first guide part, a baffle plate, an upper push plate and an upper push part, the first guide part is lower than the push rod, one end, far away from the push rod, of the first guide part is lower than one end, close to the push rod, of the first guide part, the baffle plate is installed on the first guide part, the top of the baffle plate is higher than the upper surface of the first guide part, the upper push plate is located on one side, close to the push rod, of the baffle plate, and the upper push part is connected with the upper push plate and used for pushing the upper push plate to enable the pipe to cross the baffle plate; the sampling unit includes sampling plate, power spare, and the sampling plate is located one side that the push rod was kept away from to first guide, and sampling plate and first guide keep away from and be equipped with between the push rod one end through the gap, the width more than or equal to tubular product's of gap external diameter, and power spare is connected with the sampling plate and is used for driving the sampling plate along vertical slip.

The beneficial effect of this scheme does:

1. the push rod in the scheme can push the pipe down from the conveying structure, the first guide piece can guide the pipe at the moment, and after the sampling plate slides upwards, the sampling plate plays a limiting role on the pipe, so that the pipe falls into one side of the sampling plate, which is close to the first guide piece, through a gap; after the sampling plate slides downwards, the pipe is not limited any more, so that the pipe falls to one side of the sampling plate away from the first guide piece in a parabolic shape from one end of the first guide piece away from the push rod, the pipe sampled can be separated from the pipe not sampled, sampling is automatically realized, and the workload is effectively reduced.

2. The baffle in this scheme can realize spacingly to the rolling tubular product of edge first guide, conveniently installs block structure at the tip of tubular product, also conveniently when two and more than two tubular products of dropping out simultaneously, conveniently takes a sample to a tubular product wherein.

3. In this scheme, the tubular product that is not taken a sample falls to the below of first guide, can pack in the below of first guide this moment, and the whole compact structure of this scheme, and the place that occupies is less.

Further, the sampling unit is including placing the pole, places the pole and is located the one side that the push rod was kept away from to the baffle, and places the pole and is less than the sampling plate.

The beneficial effect of this scheme does: the sampled pipe can fall on the placing rod and can not be scattered on the ground at will.

Further, place and install on the pole and place the piece, the top of placing the piece is equipped with the standing groove.

The beneficial effect of this scheme does: the second guide part plays the effect of direction to the tubular product that is not taken a sample, is convenient for lead tubular product to the packing position to avoid tubular product not have the buffering directly to fall and take place to damage or produce the mar.

Furthermore, the guide unit comprises a limiting rod and a driving piece, the limiting rod is positioned on one side of the baffle close to the push rod, and the vertical distance between the lower end of the limiting rod and the first guide piece is smaller than the outer diameter of the pipe; the driving piece is connected with the limiting rod and used for driving the limiting rod to slide.

The beneficial effect of this scheme does: when two tubular products of falling out simultaneously, the gag lever post stretches out can carry on spacingly to the tubular product that falls out afterwards, conveniently makes tubular product lapse through the push pedal one by one.

Further, the direction unit includes first L shaped plate and second L shaped plate, all is equipped with the logical groove that supplies the push rod to pass in the vertical portion of first L shaped plate and second L shaped plate, and the second L shaped plate is located one side that the baffle was kept away from to first L shaped plate, and the external diameter of perpendicular distance more than or equal to tubular product between first L shaped plate bottom and the first guide upper surface, second L shaped plate are located first guide along vertical projection.

The beneficial effect of this scheme does: first L shaped plate and second L shaped plate in this scheme can lead to the transport of tubular product, and compare with ordinary conveying structure, and the cross section of first L shaped plate and second L shaped plate in this scheme is L shape, makes things convenient for the push rod to release tubular product.

Furthermore, the upper end of the sampling plate is provided with an inclined plane, and one end of the inclined plane, which is far away from the push rod, is lower than one end of the inclined plane, which is close to the push rod.

The beneficial effect of this scheme does: the sampling board in this scheme is installed in the lapse, and the inclined plane is located the parabola form of tubular product and falls out on the route, and when the sample, tubular product falls on the inclined plane after falling out from the lower extreme of first guide, then along inclined plane downstream, falls to placing on the pole at last, and the slope in this scheme plays the effect of buffering and direction in the face of the whereabouts of tubular product, avoids tubular product downward landing highly too big at every turn and takes place to damage or produce the mar.
