[0034] The following refers to Figure 1 and Figure 2 The pipe unloading device according to the embodiments of the present application is described.

[0035] As Figure 1 and Figure 2 shown, according to the pipe unloading device of the utility model embodiment, including cutting device 100 and push plate device 400.

[0036] Cutting device 100 is used to cut pipe 800; refer to Figure 3 , Figure 4 , push plate device 400 is located in the front side of cutting device 100, and push plate device 400 includes movable push plate 410, right side first push plate lifting cylinder 421 and left side second push plate lifting cylinder 423, the upper side of movable push plate 410 is provided with push plate surface 411, the upper end of first push plate lifting cylinder 421 is rotationally connected with the right side of movable push plate 410 through cylinder pivot 422, the upper end of second push plate lifting cylinder 423 is provided with cylinder pin shaft 424, the left side of movable push plate 410 is provided with sliding groove 412, cylinder pin shaft 424 clamps sliding groove 412, cylinder pin shaft 424 can slide along sliding groove 412, and the stroke of first push plate lifting cylinder 421 is longer than that of left side second push plate lifting cylinder 423.

[0037] For example, as Figure 1 and Figure 2 shown, cutting device 100 is used to cut pipe 800, and cutting device 100 is relatively fixed and immovable during cutting. Refer to Figure 3 , Figure 4 , push plate lifting device 420 includes right side first push plate lifting cylinder 421 and left side second push plate lifting cylinder 423, first push plate lifting cylinder 421 is rotationally connected with the right side of movable push plate 410 through cylinder pivot 422, the upper end of second push plate lifting cylinder 423 is provided with cylinder pin shaft 424, the left side of movable push plate 410 is provided with sliding groove 412, cylinder pin shaft 424 clamps sliding groove 412, and cylinder pin shaft 424 can slide along sliding groove 412.

[0038] The upper side of movable push plate 410 is provided with push plate surface 411, when movable push plate 410 is in the raised state, push plate surface 411 is inclined along the direction from the upper right side to the lower left side, and push plate surface 411 can guide the cut pipe 800 to slide to the left side. In actual work, the extruder processes the pipe 800 in a continuous extrusion mode, and the pipe 800 moves from back to front after output. At this time, when movable push plate 410 is in the lowered state, push plate surface 411 is in a horizontal plane state. When movable push plate 410 is in the lowered state, push plate surface 411 can be kept in a horizontal state, ensuring that push plate surface 411 stably holds pipe 800 or push plate surface 411 does not contact pipe 800. When pipe 800 is output to a sufficient length, cutting device 100 can cut pipe 800.

[0039] After the pipe 800 is cut, the movable push plate 410 is lifted by the push plate lifting device 420, and the push plate lifting device 420 is composed of the first push plate lifting cylinder 421 on the right side and the second push plate lifting cylinder 423 on the left side, the first push plate lifting cylinder 421 is rotatably connected to the right side of the movable push plate 410 through a cylinder shaft 422, and the second push plate lifting cylinder 423 is connected to the right side of the movable push plate 410 through a cylinder pin 424, so that the flexibility and stability of the device are ensured. The cylinder pin 424 at the upper end of the second push plate lifting cylinder 423 can be clamped into the sliding groove 412 on the left side of the movable push plate 410, and the design enables the cylinder pin 424 to smoothly slide in the sliding groove 412, so that the lifting action of the push plate is realized. The stroke of the first push plate lifting cylinder 421 is longer than that of the second push plate lifting cylinder 423 on the left side.

[0040] When the movable push plate 410 is lifted, the first push plate lifting cylinder 421 and the second push plate lifting cylinder 423 lift the movable push plate 410 together, but because the stroke of the first push plate lifting cylinder 421 is longer than that of the second push plate lifting cylinder 423 on the left side, the push plate surface 411 changes from the original horizontal state to an inclined surface along the direction from the upper right side to the lower left side. In this way, it can be ensured that the movable push plate 410 can lift the pipe 800, and the conversion of the push plate surface 411 into an inclined design helps to ensure that the pipe 800 slides along the inclined angle during the operation of the movable push plate 410. In this way, the pipe 800 after being cut completes the unloading work and can be collected in the left side position of the unloading device.

[0041] The above working process realizes fully automatic operation and does not need manual operation, thereby greatly saving labor cost.

[0042] In some embodiments of the present application, the cutting device 100 can adopt a pipe cutting device in the prior art, such as an electric rotary cutting machine, a hot melting cutting machine, a laser cutting machine and the like, which will not be described here.

[0043] In some embodiments of the present application, with reference to Figure 1 , Figure 6The weighing device 300 is located in front of the cutting device 100.

The extruder processes the pipe 800 in a continuous extrusion manner, and the pipe 800 moves from back to front after being output. At this time, the weighing lifting device 320 controls the weighing sensor 310 to rise, so that the upper side of the weighing sensor 310 can hold the lower side of the pipe 800 and weigh the pipe 800. Since the density of the pipe 800 is basically fixed and uniform, only the weight of the pipe 800 needs to be determined, which is equivalent to determining the length of the pipe 800.

[0044] When the pipe 800 is output to a sufficient length, the weighing sensor 310 can sense that the pressure of the pipe 800 is large enough. Therefore, the cutting device 100 can cut the pipe 800.

The weighing sensor 310 can adopt various types of weighing sensor devices, which avoids the influence of the height of the upper side of the weighing sensor 310 on the selection and arrangement of the weighing sensor 310. The above design can also ensure the accuracy and stability of the weighing device 300 during the weighing process.

[0076] The cutting device 100 is used for cutting a pipe 800. The cutting device 100 is relatively fixed and immovable during the cutting process. The weighing device 300 is located in front of the cutting device 100. The weighing device 300 comprises a weighing sensor 310 and a weighing lifting device 320. The weighing lifting device 320 can control the lifting movement of the weighing sensor 310. The weighing sensor 310 can hold the lower side of the pipe 800 to weigh it. The push plate device 400 is located in front of the weighing device 300. The push plate device 400 comprises a movable push plate 410 and a push plate lifting device 420. The push plate lifting device 420 can control the lifting movement of the movable push plate 410. The upper side of the movable push plate 410 is provided with a push plate surface 411. When the movable push plate 410 is in the raised state, the push plate surface 411 is inclined along the direction from the upper right side to the lower left side. The push plate surface 411 can guide the cut pipe 800 to slide to the left side. The length measuring frame 500 is located in front of the push plate device 400. The upper side of the length measuring frame 500 is provided with a stroke probe 510. The stroke probe 510 can detect whether the pipe 800 reaches the predetermined position.

[0077] Since the density of the pipe 800 is basically fixed and uniform, only the weight of the pipe 800 needs to be determined, which is equivalent to determining the length of the pipe 800.

[0078] In actual work, the extruder processes the pipe 800 in a continuous extrusion mode. After the pipe 800 is output, it moves from back to front. At this time, the weighing lifting device 320 controls the weighing sensor 310 to be raised, so that the upper side of the weighing sensor 310 can hold the lower side of the pipe 800 and weigh the pipe 800.

[0079] When the pipe 800 is output to a sufficient length, the weighing sensor 310 can perceive that the pressure of the pipe 800 is large enough. At the same time, the stroke probe 510 also detects whether the front side of the pipe 800 reaches the predetermined position on the length measuring frame 500, which is equivalent to determining that the front and back sides of the pipe 800 to be cut are held by the length measuring frame 500 and the weighing device 300 respectively at this time, so as to ensure that the pipe 800 is in a proper posture. In this way, the cutting device 100 can cut the pipe 800.

[0080] After the pipe 800 is cut, the weighing lifting device 320 controls the weighing sensor 310 to descend, and at the same time, the push plate lifting device 420 controls the movable push plate 410 to rise, so that the push plate surface 411 can abut against the lower side of the pipe 800 and guide the cut pipe 800 to slide to the left side. In this way, the cut pipe 800 completes the unloading work and can be collected on the left side of the unloading device.

[0081] The above working process realizes fully automatic operation, and does not need manual operation, thereby greatly saving labor cost.

[0082] According to the pipe unloading device provided in the embodiment of the present application, the following effects can be achieved. The weighing sensor 310 of the weighing device 300 weighs the pipe 800, when the pipe 800 is output to a proper length, the stroke probe 510 of the length measuring frame 500 ensures that the pipe 800 is in a normal position, and then the cutting device 100 can cut the pipe 800, and then the push plate lifting device 420 controls the movable push plate 410 to rise, so that the push plate surface 411 can guide the cut pipe 800 to slide down and complete unloading. The above structure is simple and easy to use, and is especially suitable for use in a small and medium-sized pipe production line.
