[0033] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0034] like Figure 1-8 The figure shows a MPP tube 9 unloading device described in this embodiment, which is arranged downstream of the cutting equipment to position, fix and unload the extruded MPP tube 9. The unloading device includes components or mechanisms such as a bottom bracket 1, a bearing assembly, a lower pressure arm 6, a lifting assembly, a rotating drive mechanism 21, and a lifting mechanism 8. Among them, the bottom bracket 1 is welded from structural parts, and a rotating shaft 2 is installed on the bottom bracket 1. A matching central axis extending along a first direction is formed on the rotating shaft 2. In this embodiment, the first direction is defined as a horizontal direction. The rotating shaft 2 is mounted on the bottom bracket 1 through a bearing. The rotating drive mechanism 21 is connected to the rotating shaft 2 in a transmission manner to drive the rotating shaft 2 to rotate. The rotating drive mechanism 21 of this embodiment is a conventional mechanism in the prior art, which can be a gear mechanism or a belt drive mechanism.

[0035] The aforementioned bearing assembly is fixed to the rotating shaft 2 so as to be able to rotate around the matching central axis, and a V-shaped structure 31 is processed on the bearing assembly. The size of the V-shaped structure 31 is adapted to the MPP tube 9, and the MPP tube 9 can be placed in the V-shaped structure 31, and the two side walls of the V-shaped structure 31 are limited. The bearing assembly rotates around the matching central axis to have a bearing position in which the open end of the V-shaped structure 31 faces upward, and a deflection position away from the bearing position. When in the bearing position, the MPP tube 9 can be transported into the V-shaped structure 31 in a horizontal direction. And when in the deflection position, the open end of the V-shaped structure 31 moves to a predetermined position on the front or rear side, so that the MPP tube 9 can be disengaged from the V-shaped groove.

[0036] In this embodiment, the bearing assembly includes a plurality of bearing members 3 arranged at intervals along the first direction on the rotating shaft 2. The bearing member 3 is fixedly connected to the rotating shaft 2, and the rotation of the rotating shaft 2 can drive each bearing member 3 to move synchronously. The V-shaped structure 31 is processed on each bearing member 3.

[0037] Two V-shaped structures 31 are arranged on the bearing member 3 along the circumferential direction of the rotating shaft 2. When the bearing assembly rotates, each V-shaped structure 31 moves cyclically to the bearing position. In the specific structural design, the bearing member 3 includes two plates arranged crosswise with each other. Two V-shaped structures 31 are formed between the two plates.

[0038] The aforementioned pressing arm 6 is arranged at the rear side of the bearing assembly, and has a pressing end 61 and a contact end 62 away from the pressing end 61. The pressing arm 6 is hinged on the bottom bracket 1, and the pressing end 61 and the contact end 62 of the pressing arm 6 are arranged on opposite sides of the hinge position. The pressing arm 6 rotates forward and backward relative to the bottom bracket 1, so as to have a pressing position in which the pressing end 61 forms an upper and lower limit fit with the V-shaped structure 31 in the bearing position, and a disengagement position in which the pressing end 61 is away from the V-shaped structure 31 in the bearing position. Through the above structural design, in the pressing position, the MPP tube 9 is pressed and fixed between the pressing end and the V-shaped structure 31. In the disengagement position, the pressing end 61 is away from the MPP tube 9, so that the MPP tube 9 can be disengaged from the V-shaped structure 31. A second rubber plate 611 is installed on the pressing end 61 of the pressing arm 6. When pressing down, the second rubber plate 611 contacts the MPP tube 9 to avoid the loss of the MPP tube 9.

[0039] The aforementioned lifting assembly is arranged at the front side position of the groove bearing assembly, and is installed on the bottom bracket 1 in a sliding manner up and down through a sleeve and a guide rod. The lifting assembly has an ascending position corresponding to the bearing position and a descending position corresponding to the deflection position. In the descending position, when the bearing assembly moves to the deflection position, the lifting assembly can receive the MPP tube 9 that falls off from the V-shaped structure 31. An extension piece 41 that cooperates with the contact end 62 of the lower pressing arm 6 is fixed on the lifting assembly. In the aforementioned ascending position, the extension piece 41 abuts against the contact end 62 of the lower pressing arm 6 up and down to drive the lower pressing arm 6 to rotate around the hinge position and move to the lower pressing position. In the descending position, the extension piece 41 is movably matched with the lower pressing arm 6 so that the lower pressing arm 6 can move freely between the lower pressing position and the disengaged position. A first rubber plate 411 is installed on the extension piece 41. The first rubber plate 411 abuts against the contact end 62 of the lower pressing arm 6 to play a buffering role.

[0040] In the actual unloading operation, a transport vehicle is docked at the front side of the lifting assembly. In the aforementioned lowered position, the MPP pipe 9 is rolled onto the transport vehicle via the lifting assembly.

[0041] The aforementioned lifting mechanism 8 is installed on the bottom bracket 1, and is connected to the lifting assembly, and is used to drive the lifting assembly to move up and down. The lifting mechanism 8 is a conventional mechanism in the prior art, and is preferably a cylinder or an electric push rod.

[0042] In the specific structural design, the aforementioned lifting assembly includes a lifting bracket 4 and a lifting plate 5 fixed on the lifting bracket 4. The aforementioned plurality of lifting plates 5 are arranged at intervals along the first direction, and the plurality of lifting plates 5 and the plurality of bearing members 3 are arranged in a staggered manner in the first direction. The lifting plate 5 has a lifting end extending to a position close to the rotating shaft 2. By arranging the plurality of bearing members 3 and the plurality of lifting plates 5 in a staggered manner, the MPP pipe 9 can be smoothly and stably detached from the V-shaped structure 31 and received without obstruction, and the unloading of the MPP pipe 9 is smoother and more convenient. The aforementioned lifting plate 5 includes an inclined extension section 51 and a horizontal extension section 52 connected to each other. The inclined upper end of the inclined extension section 51 is close to the bearing member 3. The MPP pipe 9 detached from the V-shaped structure 31 is first received by the inclined extension section 51, and then rolls toward the horizontal extension section 52. The horizontal extension section 52 has a buffering effect on the MPP pipe 9. The aforementioned transport vehicle is connected to the horizontal extension section 52 . When the lifting assembly moves to the lowered position, the MPP tube 9 rolls onto the transport vehicle via the inclined extension section 51 and the horizontal extension section 52 .

[0043] In this embodiment, the aforementioned pressing arm 6 can be arranged in two or more groups. An elastic push assembly is processed on the bottom bracket 1 corresponding to the pressing arm 6. The elastic push assembly has an elastic force for pushing the pressing arm 6 to move toward the disengaged position. When the aforementioned lifting assembly moves from the ascending position to the descending position, the pressing arm 6 is pushed by the elastic force of the elastic push assembly so as to move from the pressing position to the disengaged position, so as to realize the automatic release of the pressing of the MPP tube 9. Specifically, the elastic push assembly includes a rod body 7 and a spring 71. A sliding seat is installed on the bottom bracket 1, and the rod body 7 is slidably installed in the sliding seat so as to be able to move forward and backward. The spring 71 is connected between the rod body 7 and the bottom bracket 1, and a limiting bracket 72 is fixed on one end of the rod body 7. A front and rear limiting space is formed on the limiting bracket 72. The pressing arm 6 is inserted into the limiting space and abuts against the limiting bracket 72. The elastic force provided by the spring 71 makes the pressing arm 6 always have a tendency to move toward the disengaged position.

[0044] During specific use, the bearing assembly rotates to the bearing position, and the MPP tube 9 is transported to the V-shaped structure 31 of the bearing assembly through the conveying mechanism, driving the lifting assembly to rise, so that the extension 41 cooperates with the contact end 62 of the lower pressing arm 6 to drive the lower pressing arm 6 to move to the lower pressing position, and then the lower pressing end 61 of the lower pressing arm 6 presses down the MPP tube 9, thereby realizing the positioning and fixing of the MPP tube 9. The cutting equipment cuts off the MPP tube 9 from the predetermined position. After the cutting is completed, the lifting assembly is driven to descend and the rotating bearing assembly is driven to move to the deflection position at the same time, so that the cut MPP tube 9 can detach from the V-shaped structure 31 and fall and be taken over and transferred by the lifting assembly, thereby realizing the unloading of the MPP tube 9. In addition, while the cut MPP tube 9 detaches from the V-shaped structure 31, another V-shaped structure 31 continues to synchronously take over the transported MPP tube 9 to shorten the operation time interval. Through the above-mentioned method, the MPP pipe 9 can be quickly positioned and fixed, and the cut MPP pipe 9 can be quickly unloaded, effectively meeting the needs of continuous cutting operations of the MPP pipe 9.
