The terms "first" and "second" are used merely for descriptive purposes and are not intended to have a special meaning.

The embodiment of the application provides a tubular product feeding mechanism. Referring to fig. 1 and 2, the tube feeding mechanism 100 includes a frame 110, a frame assembly 120, a conveying assembly 130, and a sensing assembly 140. As shown in fig. 1, a material frame assembly 120 is disposed on the frame 110, and the material frame assembly 120 is used for storing the tube. As shown in fig. 1, the conveying assembly 130 is disposed on the frame 110, and the conveying assembly 130 is disposed on one side of the material frame assembly 120 along a first direction, and the conveying assembly 130 is used for conveying the tube along the first direction. For convenience of description, the first direction, the second direction, and the third direction are defined in the embodiments of the present application. The first direction, the second direction and the third direction are vertical to each other. As shown in fig. 1, the first direction, the second direction, and the third direction may correspond to an X direction, a Y direction, and a Z direction of the spatial coordinate system, respectively. The first direction, the second direction, and the third direction may also be understood as a front-back direction, a left-right direction, and an up-down direction of the tube feeding mechanism 100.

When the tube is placed in the carriage assembly 120, the length of the tube is in the second direction. After the frame assembly 120 feeds the tube to the conveyor assembly 130, the tube is placed transversely on the conveyor assembly 130 in the second direction and conveyed by the conveyor assembly 130 in the first direction. Due to the long length of the tube, as shown in fig. 1, the tube can be supported and conveyed by a plurality of conveying assemblies 130, and the plurality of conveying assemblies 130 are arranged on the frame 110 at intervals along the second direction. As shown in fig. 1 and 4, the conveying assembly 130 may adopt a conveying structure such as a conveyor belt or a conveyor chain.

As shown in fig. 1, the sensing assembly 140 is multiple, the sensing assemblies 140 are disposed on the frame 110 at intervals along the second direction, and the sensing assembly 140 is disposed at one end of the conveying assembly 130 close to the material frame assembly 120. The sensing component 140 can sense whether the tube is placed on the conveying component 130. Since the situation that one end of the pipe is fed to the conveying assembly 130 and the other end of the pipe stays in the material frame assembly 120 may occur when the pipe is fed from the material frame assembly 120 to the conveying assembly 130, in the embodiment of the present application, a plurality of sensing assemblies 140 are provided, and the sensing assemblies 140 are spaced along the second direction (i.e., the length direction of the pipe). In the plurality of sensing assemblies 140, at least two sensing assemblies 140 sense the pipe, which indicates that the pipe is completely placed on the conveying assembly 130, and if only one sensing assembly 140 senses the pipe, which indicates that the pipe has one end in the material frame 121 and is not completely fed onto the conveying assembly 130, at this time, countermeasures such as alarming or shutdown processing are taken, so that subsequent feeding abnormality is avoided. In the embodiment of the present application, as shown in fig. 1, there are three groups of sensing assemblies 140, and there are three conveying assemblies 130, and one sensing assembly 140 is disposed beside each conveying assembly 130. Of course, the number of the sensing elements 140 can be adjusted as required, for example, two, four, or five groups.

In one embodiment, the sensing element 140 may be a weight sensor. The weight sensor can visually detect the pipe, and when the pipe is fed onto the conveying assembly 130, the pipe can be pressed onto the weight sensor, and can be quickly detected. And the counterweight sensor has simple structure, convenient installation and lower cost.

As shown in fig. 5, in one embodiment, the weight sensor includes a sensor bracket 141, a rotating rod 142, a sensing plate 143, a weight 144 and a sensing plate 145.

The sensing piece 145 is disposed at one end of the rotating rod 142 corresponding to the sensing piece 145. When the pipe is pressed on the sensing plate 143, the rotating rod 142 rotates around the rotating connection point with the sensor bracket 141 under the gravity action of the pipe, so as to drive the sensing piece 145 to move downwards, and the sensing piece 145 moves to enable the pipe to be sensed, which indicates that the pipe is placed on the conveying assembly 130. The weight member 144 is provided to balance the sensing plate 143, so that the light pipe or the small pipe can sense the light pipe or the small pipe by contacting the sensing plate 143, thereby increasing the sensitivity of the sensing.

As shown in fig. 5, preferably, the sensing plate 143 is disposed along a first direction, that is, the direction of the sensing plate 143 is perpendicular to the length direction of the pipe, so that the contact distance between the sensing plate 143 and the pipe is longer, and the pipe can be sensed more sensitively.

The graduated scale 155 is arranged on the shell 153, and the graduated scale 155 is used for indicating the moving distance of the baffle 152, so that the baffle 152 is adjusted to adapt to the pipe diameter of the currently cut pipe by controlling the moving distance of the baffle 152, and only one pipe can pass through between the baffle 152 and the conveying assembly 130. Above structure for the position of baffle 152 is adjustable, adapts to the tubular product of different pipe diameters.
