[0035] The frame 1 includes a base 11, a bracket 12 and a side panel 13; the base 11 is arranged on the lower side of the bracket 12, and the two are fixedly connected; the connection method can be welding, threaded connection, etc. The number of bases 11 is set according to the actual weight of the equipment, in order to meet the installation support requirements of the equipment; the base 11 can be made of I-beams. There are two side panels 13, and the two side panels 13 are located on the upper side of the bracket 12, parallel and spaced apart. The side panel 13 is fixedly connected to the bracket 12, and the connection method can be welding, threaded connection, etc. Each side panel 13 can be an integrated structure, or an assembled structure. The pipeline support assembly 2 and the pipeline conveying assembly 3 are located between the two side panels 13, and the side panel 13 provides an installation position for the pipeline support assembly 2; the pipeline cutting assembly 4 is located on the upper side of the pipeline support assembly 2.

[0036] A plurality of pipe support assemblies 2 are arranged on the frame 1, and the plurality of pipe support assemblies 2 are evenly distributed in the conveying direction of the insulation pipe 5, and jointly support the insulation pipe 5 with a relatively long length to be cut. Figure 2 As shown, each set of pipe support components 2 includes an electric roller 23 and a roller seat 24. The two ends of the electric roller 23 are rotatably mounted on the roller seat 24, and the roller seat 24 is set on the frame 1. The structure of the electric roller 23 is a prior art, and the inventor has not improved it. The electric roller 23 has a built-in motor and a reducer, and can be controlled to rotate automatically without external power; when the insulation pipe 5 is transported, the electric roller 23 does not rotate; when the insulation pipe 5 is cut, the electric roller 23 is controlled to rotate, thereby driving the insulation pipe 5 to rotate, and completing the cutting of the entire circumference of the insulation pipe 5.

[0037] Each set of pipeline support components 2 includes at least two electric rollers 23 . The two electric rollers 23 are arranged at intervals and distributed on both sides of the support plate 31 . The insulation pipe 5 is placed on the two electric rollers 23 .

[0038] In order to adapt to the insulation pipes 5 with different outer diameters, the distance between the electric rollers 23 located on both sides of the support plate 31 can be adjusted by an adjustment mechanism. Specifically, the adjustment mechanism includes a bidirectional screw 22 and a screw sleeve 25. The roller seat 24 is slidably arranged on the frame 1, and can be close to or away from the support plate 31; specifically, a plurality of slide rails 21 are arranged between the two side plates 13, and the two ends of the slide rails 21 are respectively fixed on the two side plates 13, and the plurality of slide rails 21 are parallel to each other; the roller seat 24 is slidably arranged on the slide rails 21. The bidirectional screw 22 is rotatably installed on the frame 1, and specifically, a support seat 14 is arranged on the frame 1, and the bidirectional screw 22 is rotatably installed on the support seat 14. Two screw sleeves 25 are arranged on the bidirectional screw 22, and when the bidirectional screw 22 rotates, the two screw sleeves 25 approach or move away from each other. The two screw sleeves 25 are respectively located on both sides of the support plate 31, and each screw sleeve 25 is fixedly connected to at least one roller seat 24; when the screw sleeve 25 moves axially on the bidirectional screw 22, it drives the electric rollers 23 located on both sides of the support plate 31 to move closer or farther.

[0039] Furthermore, each group of pipe support components 2 has four electric rollers 23, and the four electric rollers 23 are evenly distributed on both sides of the support plate 31. It is assumed that the two electric rollers 23 located on one side of the support plate 31 constitute the first roller group, and the two electric rollers 23 located on the other side of the support plate 31 constitute the second roller group. The two electric rollers 23 of the first roller group are coaxially arranged, and the roller seat 24 located between the two electric rollers 23 can be one or two. If two are used, the two roller seats 24 are fixedly connected; similarly, the two electric rollers 23 in the second roller group are arranged in the same manner. The screw sleeve 25 is fixedly connected to the roller seat 24 between the two electric rollers 23, controls the rotation of the bidirectional screw 22, and can adjust all the electric rollers 23 in the pipe support component 2 at the same time; and the adjustment position is also located in the middle of the first roller group and the second roller group, and the transmission stability is good.

[0040] During adjustment, the rotation of the bidirectional screw rod 22 can be manually controlled, or one end of the bidirectional screw rod 22 can be designed to be transmission-connected to the first drive device 26, and the bidirectional screw rod 22 rotates under the drive of the first drive device 26; the rotation of the bidirectional screw rod 22 is controlled, thereby controlling the distance between the two screw rod sleeves 25.

[0041] like Figure 3As shown, the pipeline conveying assembly 3 includes a support plate 31, which is horizontally arranged and located between two electric rollers 23; one or more conveying drive mechanisms are arranged on the lower side thereof, each of which has a crank 33 and a connecting rod 35; a fixed support 15 is arranged on the frame 1, and the crank 33 is rotatably mounted on the fixed support 15. One end of the connecting rod 35 is hinged to the crank 33, and the connection position deviates from the rotation center of the crank 33; the other end of the connecting rod 35 is fixedly connected to the support plate 31. The crank 33 is also transmission-connected to a second driving device 33, which can be an electric motor, in particular, a dual-output shaft motor, and the crank 33 is fixedly connected to the two output shafts. The crank 33 is transmission-connected to the support plate 31 through the connecting rod 35. In this way, the connecting rods 35 can be symmetrically arranged on both sides of the support plate 31, and the structural stability is good.

[0042] When not transporting, the support plate 31 is located at the lower side of the insulation pipe 5; when transporting the insulation pipe 5, the crank 33 rotates around its own rotation center under the drive of the second driving device 33, driving the connecting rod 35 and the support plate 31 to rise, contact the insulation pipe 5, support the insulation pipe 5 to move forward, descend, and separate from the insulation pipe 5; the above actions are performed in a cycle, thereby driving the insulation pipe 5 to be transported forward.

[0043] Furthermore, a support pad 32 is provided on the support surface of the support plate 31, and the support pad 32 is fixedly connected to the support plate 31 as a whole and moves synchronously. The upper side surface of the support pad 32 is a curved surface, which can fit well on the outer surface of the insulation pipe 5. The support pad 32 can be a rubber pad to increase the contact area and friction with the insulation pipe 5 and buffer the contact between the two.

[0044] The pipe cutting assembly 4 includes a frame 45, and the frame 45 is an inverted U-shape, and the two side walls are fixedly connected to the two side plates 13 respectively. A cutting mechanism 44 is fixedly installed on the top of the frame 45, and the cutting mechanism 44 can adopt cutting equipment such as a laser cutting machine. A number of clamping mechanisms are fixed on the side walls of the frame 45, which are used to fix the insulation pipe 5 during the cutting process; multiple clamping mechanisms are evenly distributed in the circumferential direction of the insulation pipe 5. The clamping mechanism includes a telescopic element 41, a clamping plate 42 and a clamping roller 43; the telescopic element 41 is fixedly installed on the frame 45, and its telescopic end is fixedly connected to the clamping plate 42. The telescopic element 41 can adopt parts such as a cylinder, a hydraulic cylinder, and an electric telescopic rod, and the clamping plate 42 is driven to approach or leave the insulation pipe 5 through the telescopic element 41. The side of the clamping plate 42 facing the insulation pipe 5 is the working surface, and the clamping roller 43 is rotatably installed on the working surface. The number of clamping rollers 43 can be set as needed, for example Figure 1 As shown, the number of the clamping rollers 43 is three.

[0045] When the spray-wrapped insulated pipe production equipment is in use, the insulated pipe 5 is placed between two groups of electric rollers 23; the pipeline conveying component 3 is controlled to convey the insulated pipe, and the electric roller 23 does not rotate at this time; when the set conveying distance is reached, the pipeline conveying component 3 stops conveying, and the telescopic element 41 is controlled to push the clamping plate 42 to contact the insulated pipe 5, clamping and fixing the position of the insulated pipe 5; then the electric roller 23 is controlled to rotate, and the cutting mechanism 44 is started to cut, so as to cut off the insulated pipe 5.
