[0002] In order to improve the mechanical properties of the conveying pipeline, it is usually necessary to use a winding machine to wind steel curtain tape, steel fiber tape, fiber tape and other reinforcing materials onto the plastic core tube to form a composite pipeline. The winding machine mainly includes a frame and a rotating frame pivotally connected thereto. As the plastic core tube is conveyed forward along the rotation axis of the rotating frame, the rotating frame drives the belt reel on it to rotate and release the reinforcing belt on the belt reel, thereby spirally winding the reinforcing belt onto the plastic core tube.

[0003] In the production of belt-type reinforced plastic composite pipes, thermal bonding is a key factor affecting the bonding quality and production efficiency of the reinforcing tape on the pipe. Therefore, in the existing winding machine, the pipe section before the winding position of the reinforcing tape into the pipe is usually provided with a heating device to heat the plastic core pipe and / or the reinforcing tape. At the same time, in the process of the belt reel rotating with the rotating frame, in order to ensure the stability of the reinforcing tape wound on the surface of the plastic core pipe, a pipe stabilizer is generally provided between the winding position of the reinforcing tape and the rotating frame, thereby supporting the plastic core pipe so that the plastic core pipe remains stable during the forward conveyance along the rotation axis of the rotating frame.

[0004] However, the above-mentioned prior art has at least the following defects: the distance between the heating device and the tube stabilizer is relatively close, so after a long period of operation, the temperature of the tube stabilizer will rise, and then the contact part of the tube stabilizer with the pipe will adhere to the plastic on the surface of the pipe, causing damage to the surface of the pipe. Utility Model Content

The fan is directly or through an air duct connected to an air nozzle with an air outlet facing the part of the tube stabilizer that is in contact with the tube.

[0008] Preferably, the belt winding machine also includes a frame and a rotating frame rotatably mounted on the frame, and the belt reel, heating assembly and cooling assembly are all mounted on the rotating frame so that when the rotating frame is driven to rotate relative to the frame, the reinforced belt released from the belt reel is spirally wound on the pipe running along the rotation axis of the rotating frame.

[0009] Preferably, the pipe stabilizer includes a roller mounting frame and a pipe stabilizer roller for supporting the pipe, the pipe stabilizer roller is rotatably mounted to the roller mounting frame along a rotation axis perpendicular to the running direction of the pipe and is installed to be located between the rotating frame and the heating assembly, the roller mounting frame axially passes through the rotating frame and is fixed to the frame at an end away from the pipe stabilizer roller.

[0010] Preferably, the heating assembly comprises a pipe surface heater arranged to at least partially surround and be capable of heating a portion of the pipe located upstream of a winding location where the reinforcement strip is helically wound onto the pipe.

[0011] Preferably, the pipe surface heater has a plurality of heating elements arranged along the circumference surrounding the pipe, and the heating elements are infrared ceramic heating plates, infrared lamps, electric heating rods or metal heating plates.

DETAILED DESCRIPTION

[0026] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0027] In the present utility model, unless otherwise specified, directional words such as "up, down, left, right" are generally understood in combination with the directions shown in the drawings and the directions shown in actual applications, and "inside and outside" refer to the inside and outside of the outline of the component.

[0028] Reference Figures 1 to 7 As shown, a tape winding machine according to a preferred embodiment of the present invention comprises a frame 1 and a rotating frame 2, which can be rotatably connected to the frame 1 via a slewing bearing, for example. A tape reel 4 is mounted on the rotating frame 2, and a pipe 9 such as a plastic core pipe can extend through the rotation axis of the rotating frame 2 and from the rotating frame 2. Figure 6 The right side shown moves to the left side, so that when the rotating frame 2 drives the belt reel 4 to rotate around the central axis of the pipe 9, the reinforcing tape on the belt reel 4 is released and spirally wound onto the pipe 9 to form a belt-type reinforced plastic composite pipe. In the preferred embodiment shown in the figure, four belt reels 4 arranged around the rotation axis of the rotating frame 2 are installed on the rotating frame 2. In order to facilitate the reinforcing tape released by the belt reel 4 to be well compositely bonded to the surface of the pipe 9, the belt winding machine is also provided with a heating component for heating the surface of the reinforcing tape and / or the pipe 9 to form a molten state suitable for bonding. Among them, corresponding to the four belt reels 4, the heating system can have four groups of heating components 5 corresponding to each belt reel 4. In addition, in order to ensure the stability of the pipe 9 during the movement, the belt winding machine is further provided with a pipe stabilizer 6, which can be arranged at the upstream position of the heating component 5 to support the pipe 9 to prevent the pipe 9 from having a large deviation during the movement, resulting in poor quality of the formed belt-type reinforced plastic composite pipe. Meanwhile, the belt winding machine provided by the utility model may further include a cooling assembly 7 to cool the portion of the tube stabilizer 6 that is in contact with the tube 9 to avoid adhesion to the surface of the tube 9 and damage to the tube 9 .

[0029] Therefore, in the production process of belt-type reinforced plastic composite pipes, the belt winding machine of the utility model uses the cooling component 7 to cool the part of the tube stabilizer 6 that is in contact with the pipe 9, so that the temperature of this part is within an appropriate range, thereby preventing this part from being too high in temperature, causing hot melting on the surface of the pipe 9, and causing this part to adhere to the surface of the pipe 9 and damage the pipe 9.

[0030] In some optional embodiments of the present invention, the cooling assembly may include a cooling pipe with a coolant inside, and the cooling pipe can cool down the portion of the tube stabilizer 6 that is in contact with the tube 9.

[0031] Or, preferably, in combination Figures 2 to 6As shown, the cooling assembly 7 may include a fan 71 for blowing cooling air to the portion of the tube stabilizer 6 for contacting the pipe 9 and a nozzle 73 with an air outlet facing the portion of the tube stabilizer 6 for contacting the pipe 9, wherein the fan 71 is installed to be able to rotate synchronously with the belt reel 4, for example, the fan 71 may be installed on the rotating frame 2, the belt reel moving bracket 3 described below, or the pipe surface heating mounting frame 52 described below, as long as the fan 71 can be able to rotate synchronously with the belt reel 4. In addition, the output end of the fan 71 may be directly connected to the nozzle 73, for example, when the output end of the fan 71 is close to the portion of the tube stabilizer 6 for contacting the pipe 9, the output end of the fan 71 is directly connected to the nozzle 73; or, when the output end of the fan 71 is far from the portion of the tube stabilizer 6 for contacting the pipe 9, the fan 71 is connected to the nozzle 73 through the air duct 72, so that the air outlet of the nozzle 73 can be kept close to the portion of the tube stabilizer 6 for contacting the pipe 9. Therefore, when the belt reel 4 drives the fan 71 and the air nozzle 73 to rotate around the central axis of the tube 9, the air outlet of the air nozzle 73 rotates 360° around the part of the tube stabilizer 6 that is in contact with the tube 9 to blow air, thereby improving the cooling effect of the cooling component 7.

[0032] In addition, in the belt winding machine provided by the present invention, the number of cooling components 7 can be set to one, or, in order to further improve the cooling effect of the cooling component 7, the number of cooling components 7 can also be set to multiple, and multiple cooling components 7 are arranged around the part of the tube stabilizer 6 that is used to contact the pipe 9.

[0033] In some embodiments of the present invention, the tube stabilizer 6 may include a circular tube-shaped tube stabilizer sleeve, and the tube 9 is supported by the inner wall of the tube stabilizer sleeve, wherein the tube stabilizer sleeve may be installed on the mounting frame 61 described below.

[0034] Or, refer to Figure 1-Figure 7 As shown, according to a preferred embodiment of the belt winding machine of the utility model, the tube stabilizer 6 may include a roller mounting frame 61 and a tube stabilizer roller 62 for supporting the tube 9. In the preferred embodiment shown in the figure, the tube stabilizer roller 62 is rotatably mounted to the roller mounting frame 61 along a rotation axis perpendicular to the running direction of the tube 9 and is installed to be located between the rotating frame 2 and the heating assembly 5. The roller mounting frame 61 axially passes through the rotating frame 2 and is fixed to the frame 1 through a roller mounting frame fixing member 63 at one end away from the tube stabilizer roller 62. The tube stabilizer roller 62 can support the tube 9 on the one hand to ensure the stable movement of the tube 9 during the process of winding the reinforcing strip; on the other hand, when the tube 9 moves, the tube stabilizer roller 62 can rotate, thereby reducing the friction between the tube stabilizer roller 62 and the tube 9, and preventing the tube stabilizer roller 62 from wearing the tube 9.

[0035] Figures 2 to 5The heating assembly 5 that can be used for the belt winding machine provided by the utility model is shown, wherein the heating assembly 5 may include a pipe surface heater 51, which is arranged to at least partially surround and heat the pipe 9, which is located upstream of the winding position where the reinforcing tape is spirally wound on the pipe 9. It can be understood that the "winding position" refers to the initial position where the reinforcing tape is in contact with the pipe 9 during the process of the reinforcing tape released by the reel 4 being spirally wound onto the pipe 9. It should be noted that the pipe surface heater 51 can be set to various suitable structures and heating forms. In a preferred embodiment, the pipe surface heater 51 can have a plurality of heating elements arranged along the circumference of the surrounding pipe 9, for example, a plurality of heating elements can be installed on the side of the heater shell of the pipe surface heater 51 facing the pipe 9, and arranged along the circumference of the surrounding pipe 9. Among them, the heating element can be selected from an infrared ceramic heating plate, an infrared lamp tube, an electric heating rod or a metal heating plate, etc., preferably a heating element that does not emit light or emits low light, so as to reduce the stimulation and damage of strong light to the human eye.

[0036] Continue to refer to Figures 2 to 5 As shown, in a belt winding machine according to a preferred embodiment of the utility model, a belt reel movable bracket 3 can be installed on the rotating frame 2, and the belt reel 4 can be installed on the movable bracket 3, thereby, the belt reel movable bracket 3 can be adjusted to move the belt reel 4 to different axial relative positions along a direction parallel to the central axis of the tube 9, that is, in the preferred embodiment shown in the figure, the belt reel movable bracket 3 is arranged to be able to move relative to the rotating frame 2 along a direction parallel to the central axis of the tube 9, so as to synchronously adjust the axial position of the belt reel 4 thereon.

[0037] In the belt winding machine provided by the utility model, combined with Figures 2 to 4 As shown, the pipe surface heater 51 can be installed on the rotating frame 2 through the pipe surface heating mounting frame 52, so that the pipe surface heater 51 can rotate around the central axis of the pipe 9 along with the rotating frame 2 to heat the outer circumference of the pipe 9. Of course, in another optional embodiment of the utility model, the pipe surface heating mounting frame 52 can be installed on the reel moving bracket 3.

[0038] As mentioned above, the cooling assembly 7 may include a fan 71 for blowing cooling air to the portion of the tube stabilizer 6 that is in contact with the tube 9, and the fan 71 may be directly mounted on the end surface of the rotating frame 2. In a preferred embodiment of the present utility model, the cooling assembly 7 may also include a fan mounting seat 74 for mounting the fan 71, so as to facilitate the installation and removal of the fan 71. Figure 2-Figure 7As shown, the fan mounting seat 74 can be mounted on the end surface of the rotating frame 2, the belt disk movable bracket 3 or the pipe surface heating mounting frame 52, so that the cooling assembly 7 can rotate around the central axis of the pipe 9 along with the rotating frame 2, thereby improving the cooling effect of the cooling assembly 7. Specifically, the fan mounting seat 74 is mainly installed on the pipe surface heating mounting frame 52 as an example for description. Figure 3 and Figure 5 As shown, the tube surface heating mounting bracket 52 may include a first connecting rod extending in a direction parallel to the central axis of the tube 9 and a second connecting rod extending in a radial direction of the tube 9, the first connecting rod may be fixed on the end face of the rotating frame 2, one end of the second connecting rod is connected to the first connecting rod through a second connecting rod cross-joint, and the other end is connected to the tube surface heater 51, a fan mounting seat 74 equipped with a fan 71 may be connected to the first connecting rod through a cross-joint 75, and is located upstream of the tube surface heater 51, that is, in the preferred embodiment shown in the figure, the fan mounting seat 74 is located on the side of the tube surface heater 51 close to the rotating frame 2.

[0039] In addition, combined Figure 2-Figure 7 , the air outlet of the air nozzle 73 can be directly directed toward the tube stabilizer roller 62, so that the cooling air blown by the fan 71 can be directly blown toward the tube stabilizer roller 62 to cool down the tube stabilizer roller 62. Alternatively, in another optional embodiment of the utility model, the air outlet of the air nozzle 73 can be directed toward the position where the adjacent tube 9 contacts the tube stabilizer roller 62, wherein the position refers to the position of the tube 9 between the heating component 5 and the tube stabilizer 6 and adjacent to the tube stabilizer 6. It should be noted that the air outlet direction of the air nozzle 73 is adjusted to extend along the radial direction of the tube 9, or to extend in the direction away from the tube surface heater 51, so as to prevent the cooling air blown by the fan 71 from blowing toward the tube surface heater 51 or the part of the tube 9 that is heated by the tube surface heater 51, thereby affecting the heating effect of the tube surface heater 51 on the tube 9.

[0040] Furthermore, in the belt winding machine provided by the present invention, a baffle 8 at least partially disposed between the tube stabilizer 6 and the heating assembly 5 may be included. The addition of the baffle 8 may further prevent the cooling air blown by the fan 71 from blowing toward the tube surface heater 51 or the portion of the tube 9 that is heated by the tube surface heater 51, thereby affecting the heating effect of the tube surface heater 51 on the tube 9. The baffle 8 may be installed on the end face of the tube surface heater 51 close to the tube stabilizer, or, in another embodiment of the present invention, refer to Figure 7As shown, the baffle 8 can be installed on the air nozzle 73. Of course, the baffle 8 can also be installed on the fan 71, and the specific installation position can be adjusted according to the actual production site conditions, as long as it can prevent the cooling air blown by the fan 71 from blowing to the pipe surface heater 51 or the part of the pipe surface heater 51 on the pipe 9 that is heated by the pipe surface heater 51.

In addition, the production line may also include an extruder, a cooling box, a traction machine and an oven, wherein the production raw materials are put into the extruder, and the pipe 9 is formed through a mold at the output end of the extruder, and then the pipe 9 enters the cooling box for cooling. The traction machine is arranged downstream of the cooling box to provide traction for the movement of the pipe 9, so that the pipe 9 continuously moves toward the strip-winding machine; the oven is arranged downstream of the strip-winding machine, and is used for heating the entire reinforcing strip after it is spirally wound onto the pipe 9, so that the reinforcing strip is reliably bonded to the pipe 9 and adjacent reinforcing strips.
