[0002] During the production process of pipe fittings, a chain plate conveyor is usually used to transport the pipe fittings to a preset blanking area, which is used to achieve the blanking of the pipe fittings or to transfer the pipe fittings to the next working station.

[0003] When the chain plate conveyor transports the pipe fittings to the output side, pipe fitting accumulation will occur. Therefore, workers need to directly carry or use lifting equipment to carry the pipe fittings on the output side to avoid the occurrence of pipe fitting accumulation on the output side. However, the inventor found that this method not only has a high fatigue strength, but also has low efficiency in sending the pipe fittings to the blanking area, which will seriously affect the production efficiency of the pipe fittings.

[0070] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Embodiments

[0071] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the embodiments of the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the embodiments of the present application as detailed in the appended claims.

[0072] The following uses specific embodiments to elaborate in detail on the technical solutions of the embodiments of the present application and how the technical solutions of the embodiments of the present application solve the current problems. The following several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be elaborated in some embodiments. The following will describe the embodiments of the embodiments of the present application in conjunction with the accompanying drawings.

[0073] Please refer to Figures 1 - 3 , the embodiments of the present application provide a push tube device for pushing out pipe fittings on a chain plate conveyor. The push tube device includes: at least one push plate 1, a rotating shaft 2, a driving mechanism 3, and a supporting mechanism 4;

[0074] At least one push plate 1 is sequentially connected to the rotating shaft 2, and the push plate 1 is perpendicular to the axial direction of the rotating shaft 2;

[0075] One end of the rotating shaft 2 is connected to the driving mechanism 3, and the other end of the rotating shaft 2 is rotatably connected to the supporting mechanism 4. The driving mechanism 3 is used to rotate the rotating shaft 2.

[0076] In this example, by rotating the rotating shaft 2 through the driving mechanism 3, the rotating shaft 2 drives the push plate 1 to rotate; the push plate 1 will contact the pipe fittings on the chain plate of the chain plate conveyor and push the pipe fittings onto the push plate 1, achieving the technical effect of picking up the pipe fittings through the push plate 1. Continuing to rotate the rotating shaft 2, the push plate 1 will lift the pipe fittings. At this time, at least one push plate 1 supports the pipe fittings to be lifted and pushes them to the preset blanking area. Therefore, not only is it possible to avoid a large number of pipe fittings from accumulating on the output side of the chain plate conveyor, resulting in congestion on this output side, but also there is no need to use hoisting or manual handling of the pipe fittings accumulated on the output side of the chain plate conveyor, improving the efficiency of sending the pipe fittings to the blanking area, ensuring the production efficiency of the pipe fittings, and reducing the fatigue intensity of workers.

[0077] In a preferred embodiment, the push plate 1 is perpendicular to the axis of the rotating shaft 2;

[0078] The push plate 1 includes a connecting portion 11 and a pushing portion 12;

[0079] The top end of the connecting portion 11 is connected to the rotating shaft 2;

[0080] The bottom end of the connecting portion 11 is connected to the top end of the pushing portion 12;

[0081] The side edges of the connecting portion 11 and the pushing portion 12 form an arc-shaped groove 13.

[0082] In this example, by the push plate 1 being perpendicular to the axis of the rotating shaft 2, the side edge of the push plate 1 can contact and push the pipe fittings.

[0083] By pushing the side of the pushing plate 1 against the pipe fitting, sufficient support force is ensured during the pushing process to avoid deformation of the pipe fitting.

[0084] The arc-shaped groove 13 is used to accommodate the pipe fitting to ensure the stability of the pipe fitting during the process of the pushing plate 1 pushing out the pipe fitting.

[0085] Optionally, the pushing plate 1 is an integrally formed structure, and the connecting portion 11 and the pushing portion 12 form a T-shaped structure.

[0086] In a preferred embodiment, at least one pushing plate 1 is arranged equidistantly or non-equidistantly on the rotating shaft 2.

[0087] In this example, by arranging at least one pushing plate 1 equidistantly on the rotating shaft 2, different-sized pipe fittings can be supported by two or more pushing plates 1 and the pipe fittings can be pushed out of the chain conveyor.

[0088] By arranging at least one pushing plate 1 non-equidistantly on the rotating shaft 2, each pushing plate 1 can be arranged according to the pipe fittings actually produced in the factory, ensuring that each type of pipe fitting can be reliably pushed out of the chain conveyor.

[0094] The variable-frequency motor 31 of the present application is a motor that adjusts the motor speed and output power through a frequency converter (also known as a variable-frequency speed regulator). The frequency converter controls the operating state of the motor by changing the power frequency and voltage, thereby achieving precise speed and torque control.

[0095] The variable-frequency motor 31 of the present application can adjust the motor speed according to actual needs, thereby reducing unnecessary energy consumption and achieving an energy-saving effect.

[0096] The variable-frequency motor 31 of the present application can achieve smooth start and stop of the motor, reduce mechanical shock, and extend the service life of the equipment.

[0097] The speed regulation range of the variable-frequency motor 31 of the present application is generally relatively wide, and it can maintain stable operation at a very low speed.

[0113] The driving bearing 35 is fixed on the driving frame 33;

When the number of turns calculated by the encoder 43 reaches the preset turn threshold, a stop signal is sent to the frequency conversion motor 31; the frequency conversion motor 31 stops according to the stop signal to avoid the long-term idling of the rotating shaft 2.

[0138] The encoder 43 is fixed in at least one support bracket 421, on the support crossbeam 4211 of the support bracket 421 close to the driving mechanism 3.
