DETAILED DESCRIPTION

[0033] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 10 It will be clearly presented in the detailed description of the embodiments. Those skilled in the art should understand that these implementation modes are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. The structural contents mentioned in the following embodiments are all based on the drawings in the specification as reference.

[0034] Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0035] As attached Figure 1 -Attached Figure 8 As shown, a bamboo-wound hollow solid wall pipe traction production line comprises a main machine 1, a rotating shaft 2 is rotatably installed on the front side of the main machine 1, a driving motor connected to the rotating shaft 2 is installed inside the main machine 1, and can drive the rotating shaft 2 to rotate, a traction machine 3 is fixedly installed on the front end of the rotating shaft 2, and the outer side of the traction machine 3 can be wound to produce a bamboo-wound hollow wall pipe 101;

[0036] The traction machine 3 includes multiple groups of traction support plates 301 fixedly installed at the front end of the rotating shaft 2 and evenly distributed in the circumferential direction, each group of the traction support plates 301 has two, and both ends of each group of the traction support plates 301 are rotatably installed with traction wheels 302, and a traction belt 303 is installed between the two traction wheels 302. Multiple traction belts 303 are evenly distributed in the circumferential direction on the front side of the rotating shaft 2, and rubber blocks 304 are fixedly installed at regular intervals on the outer surface of each traction belt 303, and a traction motor 305 connected to the traction wheel 302 located at the rear side is fixedly installed at the rear end of each group of the traction support plates 301;

[0037] On one side of the traction machine 3, from left to right, there are placed an inner lining layer feeder 04, a vertical rib bamboo strip board feeder 05, an axial bamboo strip board feeder 06, a circumferential bamboo strip board feeder 07, and a surface layer feeder 08.

[0038] The traction wheel 302 can be selected as a sprocket, and the traction belt 303 can be selected as a chain, which can realize synchronous rotation through multiple groups of sprocket groups, thereby driving the inner lining layer 4 to spirally wind forward.

[0039] The traction wheel 302 can be selected as a synchronous pulley, and the traction belt 303 can be selected as a synchronous belt, which can realize synchronous rotation through multiple sets of synchronous pulleys, thereby driving the inner lining layer 4 to spirally wind forward.

[0040] The traction wheel 302 can be selected as a track wheel, and the traction belt 303 can be selected as a track, which can realize synchronous rotation of multiple sets of track wheels, thereby driving the inner lining layer 4 to spirally wind forward.

[0041] The bamboo-wound hollow solid-wall pipe 101 includes an inner lining layer 4, which is spirally wound on the outside of the traction machine 3. A vertical rib bamboo strip strip 5 is wound on the outside of the inner lining layer 4. The vertical rib bamboo strip strip 5 can be spirally wound on the outside of the inner lining layer 4 at intervals to form spirally spaced vertical ribs. The size of the interval can be adjusted to form spiral vertical ribs with different intervals. When the size of the interval is zero, a solid-wall pipe can be obtained. An axial bamboo strip strip 6 is wound on the outside of the vertical rib bamboo strip strip 5. An circumferential bamboo strip strip 7 is wound on the outside of the axial bamboo strip strip 6. A surface layer 8 is wound on the outside of the circumferential bamboo strip strip 7.

[0042] The inner lining layer 4, the vertical bamboo strip board belt 5, the axial bamboo strip board belt 6, the annular bamboo strip board belt 7 and the surface layer 8 are bonded together by thermoplastic resin.

[0043] A glue extruder is placed on one side of the traction machine 3, and the glue extruder is connected to a glue delivery pipe 9 located below the inner lining layer 4, the vertical rib bamboo strips 5, the axial bamboo strips 6, the annular bamboo strips 7, and the surface layer 8. The outer side of the glue delivery pipe 9 is connected to multiple glue extrusion heads 10.

[0044] The specific production steps are:

[0045] a. First, fix one end of the lining layer 4 on the outside of the tractor 3, start the main machine 1 so that the rotating shaft 2 drives the tractor 3 to rotate and drive the lining layer 4 to start winding. Since there are multiple traction belts 303 and they are distributed in a circle, the lining layer 4 can be quasi-circular or circular after being wound on the outside;

[0046] b. Simultaneously start multiple traction motors 305, so that multiple traction belts 303 rotate and drive the inner liner layer 4 to spirally wind forward;

[0047] c. When the front end of the inner lining layer 4 reaches the vertical rib bamboo strip board feeder 05, the vertical rib bamboo strip board 5 begins to be spirally wound around the outer side of the inner lining layer 4. After the vertical rib bamboo strip board 5 is wound, Figure 8 As shown, there is a gap, and in order to make the vertical rib bamboo strip strip 5 wind a certain thickness, multiple vertical rib bamboo strip strip feeders 05 can be set according to demand to wind it toward the outside of the inner lining layer 4;

[0048] d. According to the above operation, the axial bamboo strips 6, the circumferential bamboo strips 7 and the surface layer 8 are spirally wound in sequence. During the winding, the thermoplastic resin glue sprayed out from the glue extruder 10 is used to bond them. After the thermoplastic resin glue is cooled, a bamboo-wound hollow-wall pipe 101 is obtained. The traction machine in the present invention can continuously pull the wound lining layer 4, replacing the situation in the prior art where a steel belt is used for support and movement, and also eliminating the steel belt circulation mechanism, steel belt correction mechanism and steel belt rotation mechanism in the traditional production line, so that the structure of the bamboo-wound hollow-wall pipe production line becomes simpler, easy to implement and has good practicality.

[0049] As attached Fig. 9 , Attachment Fig.10 As shown, in addition to manufacturing the above-mentioned hollow and solid wall pipes, the present invention can also be used to produce the following Fig.10 The vertical storage tank with a conical cross section shown in the figure can be operated in practice by adjusting the rotation speed of the plurality of traction belts 303 while the rotation speed of the rotating shaft 2 remains unchanged. When the rotation speed of the traction belt 303 is slow, the pitch of the inner lining layer 4, the vertical rib bamboo strips belt 5, the axial bamboo strips belt 6, the circumferential bamboo strips belt 7, and the surface layer 8 wound on the outside of the traction belt 303 becomes smaller, thereby increasing the number of windings and increasing the diameter; when the rotation speed of the traction belt 303 gradually becomes faster, the pitch of the inner lining layer 4, the vertical rib bamboo strips belt 5, the axial bamboo strips belt 6, the circumferential bamboo strips belt 7, and the surface layer 8 wound becomes larger, thereby decreasing the number of windings; then the rotation speed of the traction belt 303 gradually becomes faster again, thereby forming the attached Fig. 9 The diameter of the unequal wall pipe shown in the figure has a variation of "large-small-large-small...", where the diameter of the unequal wall pipe is the largest and the diameter is the smallest (see the attached figure). Fig. 9 The dashed line in the middle is cut off to obtain the following Fig.10 The vertical storage tank.
