[0025] Reference Figure 1 , Figure 2 and Figure 3 According to an embodiment of the present invention, a bamboo tube manufacturing device (hereinafter referred to as the device) is used to drive the inner lining 003 to rotate, thereby winding the cloth 002 and bamboo skin 001 onto the inner lining 003 to form a bamboo tube.

[0026] Bamboo veneer 001 refers to a thin, skin-like object made mostly or entirely of bamboo. Specifically, it can be a thin veneer material cut from pure natural bamboo, or a bamboo-based composite material, i.e., a material mainly composed of bamboo and other materials, such as cross-laminated bamboo sheets, including bamboo sheets and adhesives. Fabric 002 is a flexible supporting object. The specific material of fabric 002 is not limited to common materials used in home textiles (such as nylon, polyester, cotton, wool, etc.), but can also be industrial or other special-purpose materials, such as fiberglass, basalt fiber, etc.; specifically, in some embodiments, it can be fiberglass mesh. Lining 003 is generally a tubular object, usually a round tube, but can also be a square tube or other complex-shaped tube. Lining 003 is the attachment for the bamboo veneer 001 and fabric 002, and also provides a certain degree of isolation and support. Lining 003 can be a metal tube or a plastic tube, such as a food-grade stainless steel lining 003 tube, PVC tube, PE tube, etc. Adhesive is a sticky substance that can bond two objects together (or glue them together). In this invention, adhesive is mainly used to bond and fix the fabric 002 and bamboo skin 001 between different layers (after the bamboo skin 001 and fabric 002 have been wrapped around the inner lining 003 once, the next layer of bamboo skin 001 will be glued and fixed to the fabric 002). It can also fix the fabric 002 and bamboo skin 001 of the same layer by gluing, or it can glue (or bond, adhesive) the bamboo skin 001 and fabric 002 to the inner lining 003. Specifically, in this embodiment, a self-developed silicone adhesive is used for gluing.

[0027] It should be understood that in this utility model, the description of "bamboo skin 001" is only to illustrate the structure of the equipment and the functions produced by the structure. "Bamboo skin 001" is not part of the structure of the equipment, nor is it a limitation on the structure of the equipment. That is, in the actual product, the equipment may not contain bamboo skin 001, and the absence of bamboo skin 001 does not affect the structure of the equipment. It should also be understood that similar terms in other contents of this utility model (such as "fabric 002", "lining 003", "adhesive", etc.) should also be understood with reference to this clause.

[0028] The winding device 1100 includes a base 100, a winding guide rail 1130, a winding drive mechanism 1110, a winding claw 1120, and a winding lifting mechanism 1140. The winding guide rail 1130 is mounted on the base 100. The winding drive mechanism 1110 is slidably connected to the winding guide rail 1130 and can slide relative to the winding guide rail 1130. The winding claw 1120 is connected to the winding drive mechanism 1110, and the winding drive mechanism 1110 can drive the winding claw 1120 to open or retract, thereby abutting or releasing the inner lining 003. The winding drive mechanism 1110 can also drive the winding claw 1120 to rotate, thereby causing the inner lining 003 to rotate. The winding lifting mechanism 1140 is mounted on the base 100 and is used to support and drive the inner lining 003 and the bamboo tube to rise and fall. The bamboo tube manufacturing equipment of this utility model is equipped with a winding and lifting mechanism 1140. The winding and lifting mechanism 1140 can automatically lift the inner liner 003, making the installation of the inner liner 003 simpler and more convenient, and can also support the manufactured bamboo tubes to prevent them from falling and getting bumped.

[0029] The feeding device 200 can be a simple metal table, wooden table, etc., or a complex device with some special functions, such as a device that can automatically lift and adjust the height of the top bamboo skin 001.

[0030] The fabric feeding device is mainly a device for storing fabric 002 (or, in other words, the other end of fabric 002 is connected to the fabric feeding device); specifically, fabric 002 is generally wound on a roll, and the roll can rotate actively to actively release fabric 002, or the roll can only rotate passively. When fabric 002 is pulled, the roll rotates passively (one end of fabric 002 is fixed to the inner lining 003, and when the inner lining 003 rotates, it winds fabric 002, thereby driving the roll to rotate) to release fabric 002. Fabric 002 can also be placed and stored in other ways, such as folding and stacking together. The connection between one end of the fabric 002 and the inner lining 003 (the initial connection of fixing one end of the fabric 002 to the inner lining 003 during the initial winding and tube making) can be glued or connected by other methods, such as heat fusion, welding (the fabric 002 contains metal wires and the inner lining 003 is a metal material), or other objects fixing the fabric 002 to the inner lining 003 (such as multiple clamping structures clamping and fixing the fabric 002 to the inner lining 003).

[0031] The material conveying device can fix and transport bamboo peel 001 in various ways. Specifically, fixing methods include clamping and transporting with grippers, adsorption and transporting with suction cups 310, magnetic adsorption and transporting with relative fixation through interference fit friction. Transporting methods include transporting with multi-joint robotic arms, transporting with guide rail sliders, transporting with conveyor belts, transporting with rollers rotating below the bamboo peel 001, and hoisting transport. Furthermore, 'transporting bamboo peel 001 to fabric 002' can be done directly in one go, or it can be done in multiple steps (or in multiple segments). It should be understood that the first material conveying device 300 transporting bamboo peel 001 to fabric 002 can be done directly to fabric 002 or indirectly to fabric 002 (or it can be an intermediate step or process in the process of transporting bamboo peel 001 to fabric 002).

[0032] The gluing device applies glue to bamboo veneer 001 and fabric 002 through spraying, coating, sprinkling, roller coating, or other methods, such as immersing the material in a glue tank. Roller coating is a physical coating process that uses a rotating roller to form a wet film. It is a processing method that uses a rotating roller to apply coating to the surface of materials such as fabric 002 and metal plates. Roller coating uses less glue, reduces odor, and provides more even application, so it is generally preferred for gluing work. One, several, or a combination of bamboo veneer 001, fabric 002, glue, lining 003, and bamboo tube can be referred to simply as the materials.

[0033] The winding device 1100 drives the inner lining 003 to rotate, while one end of the fabric 002 is fixedly connected to the inner lining 003, and the bamboo skin 001 is on the fabric 002. Therefore, when the inner lining 003 rotates, it drives the fabric 002 and the bamboo skin 001 on the fabric 002 to wrap around the inner lining 003, and the fabric 002 and bamboo skin 001 are glued together. After curing, a bamboo tube can be formed.

[0034] It should be understood that the various devices, mechanisms, and components mentioned above and below can be independent, unconnected (or even completely different from each other) individual parts when bamboo tube manufacturing is not being carried out. Therefore, when the equipment is actually being produced, transported, or sold, some devices, mechanisms, and certain more specific components (such as motors and cutting tools) may be temporarily missing.

[0035] The base 100 is the basic carrier for installing and fixing the components of this equipment. It is a conceptual object and can be any object, such as a metal platform, stone platform, wooden table, bracket, support plate, support frame, bearing seat, mounting plate 1143, reinforcing rib, hook, ground, ceiling, etc. It is an object that reuses or combines one or more components to play a role in fixing and supporting.

[0036] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the winding device 1100 includes a winding drive mechanism 1110, a winding claw 1120, and a winding guide rail 1130. The winding guide rail 1130 is disposed on the base 100. The winding drive mechanism 1110 is slidably connected to the winding guide rail 1130 and can slide relative to the winding guide rail 1130. The winding drive mechanism 1110 is connected to the winding claw 1120. The winding drive mechanism 1110 can drive the winding claw 1120 to open or retract, and the winding drive mechanism 1110 can also drive the winding claw 1120 to rotate.

[0037] The winding drive mechanism 1110 can slide relative to the guide rail, thus moving away from or closer to the inner liner 003 (generally in the left-right direction). Since the outer surface of the inner liner 003 needs to be wrapped with material, and the inner liner 003 is roughly a tubular part, the inner liner 003 is fixed by retracting the winding claw 1120, inserting it into the inner liner 003, and then opening it to abut against and support the inner wall of the inner liner 003. Specifically, before the inner liner 003 is installed, the winding claw 1120 is in a retracted state, and the winding drive mechanism 1110 is away from the inner liner 003. When the inner liner 003 is installed, the winding drive mechanism 1110 moves closer to the inner liner 003 along the winding guide rail 1130, inserts the winding claw 1120 into the inner liner 003, and then the winding drive mechanism 1110 drives the winding claw 1120 to open, so that the winding claw 1120 abuts against and supports and fixes the inner liner 003. It should be understood that the winding drive mechanism 1110 can have two drive sources (servo motors) that can drive the rotation of both sides of the inner liner 003. Alternatively, the winding drive mechanism 1110 can be equipped with only one drive source (servo motor) that drives the winding jaw 1120 and inner liner 003 on one side to rotate actively, while the winding jaw 1120 and inner liner 003 on the other side rotate passively.

[0038] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the winding device 1100 further includes a winding lifting mechanism 1140, which is disposed on the base 100 (located below the inner liner 003 and used to lift the inner liner 003).

[0039] The winding lifting mechanism 1140 is set up so that the inner liner 003 is simply placed on it, and the mechanism lifts it up until the winding claw 1120 inserts and secures it. It's important to understand that since only the winding claw 1120 needs to be inserted into the inner liner 003, and the claw automatically adjusts its position after opening, and the internal space of the inner liner 003 is relatively large compared to the contracted winding claw 1120, the precision requirement for lifting the inner liner 003 is very low. The specific composition and working principle of the winding lifting mechanism 1140 can be found in existing technology. For example, it can be similar to the lifting mechanism 220 in the unloading device 200, using a scissor-type lifting platform with a central arc-shaped groove for coarse positioning of the inner liner 003. The small arc of the groove makes it suitable for inner liners 003 of different sizes. It should be understood that the winding lifting mechanism 1140 can also play an auxiliary role in winding the bamboo tube after the bamboo tube manufacturing is completed. Specifically, when the bamboo tube manufacturing is completed, the winding lifting mechanism 1140 is raised, and the winding drive mechanism 1110 drives the winding claw 1120 to retract. The bamboo tube can generally fall on the winding lifting mechanism 1140. The winding drive mechanism 1110 drives the winding claw 1120 away from the inner liner 003. Subsequently, the bamboo tube can be removed from the winding lifting mechanism 1140, or it can be removed after the winding lifting mechanism 1140 is lowered again.

[0040] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the winding lifting mechanism 1140 includes a first support column 1141, a second support column 1142, a mounting plate 1143, and a winding lifting drive assembly 1144. The first support column 1141 and the second support column 1142 are arranged one after the other at a predetermined distance. Both the first support column 1141 and the second support column 1142 are connected to the mounting plate 1143. The winding lifting drive assembly 1144 is connected to the mounting plate 1143 and can drive the mounting plate 1143 to rise and fall (thereby driving the first support column 1141 and the second support column 1142 to rise and fall).

[0041] The inner lining 003 and bamboo tube can be placed between two support columns, supported and fixed to a certain extent by the two support columns. Setting two support columns to support and store the inner lining 003 and bamboo tube can not only meet the storage needs of materials of different sizes, but also have a certain limiting and fixing effect on the materials (preventing them from moving back and forth), preventing the materials from accidentally falling off the winding lifting mechanism 1140 (for example, rolling out of a groove with a small curvature) and rolling around in the production area, which could lead to material damage or even personnel danger. Especially at the moment when the winding lifting mechanism 1140 stops lifting, the speed change is large, and there is a certain impact force, inertial force and vibration, which may cause the materials to escape.

[0042] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the winding device 1100 further includes a discharge mechanism 1150, which is disposed on the base 100.

[0043] The discharging mechanism 1150 is used to remove (or take out, push out, or eject) the bamboo tubes temporarily stored on the winding lifting mechanism 1140. The discharging mechanism 1150 removes the bamboo tubes from the production area, facilitating their subsequent transportation and storage. This eliminates the need for personnel to approach the production area to retrieve the bamboo tubes, which could pose several risks: firstly, it could lead to danger (such as contact with moving parts or sharp corners of the equipment, or the high temperature of the bamboo tubes potentially posing a risk to unprotected personnel); secondly, the area contains volatile chemicals, and personnel should avoid prolonged proximity to this area; and thirdly, other components can be added later to transport and store the removed bamboo tubes, such as a slide rail that allows the removed bamboo tubes to roll directly to the storage area. The specific structure and working principle of the discharging mechanism 1150 are not limited here and can take various forms; for example, using a multi-jointed robotic arm to grasp and store the bamboo tubes, pushing them out from the side, or using a component similar to the winding claw 1120 mentioned above, inserting it into the inner liner 003 and then dragging it away.

[0044] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the discharge mechanism 1150 includes a push cylinder 1151 and a push block 1152. The push cylinder 1151 is mounted on the base 100 and is connected to the push block 1152. The push block 1152 is provided with a push inclined surface 1152a (the push inclined surface 1152a is used to abut against the outer surface of the bamboo tube and push the bamboo tube out from the winding lifting mechanism 1140).

[0045] The push cylinder 1151 can be a pneumatic cylinder, hydraulic cylinder, electric cylinder, etc. The push cylinder 1151 is located below the inner liner 003. The push block 1152, by setting the push inclined surface 1152a, can push the bamboo tube from the side and below, thereby pushing the bamboo tube out of the winding lifting mechanism 1140. The push inclined surface 1152a, after abutting against the bamboo tube, can decompose the pushing force into two forces on the bamboo tube. One is a force that lifts the bamboo tube from bottom to top, freeing the bamboo tube from the limit of the lifting mechanism 220, so that the lifting mechanism 220 can no longer limit the movement of the bamboo tube. The other is a pushing force from front to back, pushing the bamboo tube backward. It should be understood that, due to the setting of the pushing inclined surface 1152a, the direction of movement of the pushing cylinder 1151 driving the pushing block 1152 is less restricted. As long as the pushing block 1152 is roughly located in the area below the front side of the bamboo tube, the pushing of the bamboo tube can be achieved. For example, the direction of movement of the pushing cylinder 1151 driving the pushing block 1152 can be below the bamboo tube, pushing the bamboo tube from bottom to top; the direction of movement of the pushing cylinder 1151 driving the pushing block 1152 can also be on the side of the bamboo tube, pushing the bamboo tube from front to back. In some specific embodiments, the pushing cylinder 1151 is located between the first supporting column 1141 and the second supporting column 1142, which can make full use of the internal space of the equipment without encroaching on the space of other areas of the equipment. The pushing cylinder 1151 pushes the bamboo tube from bottom to top. Specifically, after the bamboo tube is manufactured, the winding and lifting drive assembly 1144 drives the mounting plate 1143 to rise, thereby driving the first supporting column 1141 and the second supporting column 1142 to rise. The winding drive mechanism 1110 drives the winding claw 1120 to retract, and the bamboo tube falls onto the first supporting column 1141. On the 41st and the second support column 1142, the winding drive mechanism 1110 drives the winding claw 1120 away from the inner liner 003. The winding claw 1120 extends out of the inner liner 003. The winding lifting drive assembly 1144 drives the mounting plate 1143 to descend, thereby driving the first support column 1141, the second support column 1142 and the bamboo tube to descend. The push cylinder 1151 drives the push block 1152 to push upward, pushing the bamboo tube out from between the first support column 1141 and the second support column 1142. The push cylinder 1151 drives the push block 1152 to retract.

[0046] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the fabric feeding device includes a fabric roll, which is used to wind and store fabric 002 (or, the other end of fabric 002 is connected to the fabric roll).

[0047] It is important to understand that the unwinding device may also include an unwinding drive, which is connected to the fabric roll. The unwinding drive can drive the fabric roll to rotate and actively unwind the fabric 002. Setting the unwinding drive to actively unwind the fabric 002 can reduce the pulling force required by the lining 003 to pull the fabric 002, preventing excessive pulling force that could cause the fabric 002 to detach from the lining 003 or even break. Furthermore, the unwinding drive and the drive components of the winding device 1100 can both be servo motors, which facilitates the control of motor speed. For example, as the roll diameter increases, the system automatically calculates the moment of inertia and adjusts the torque output in real time, thereby adjusting the winding and unwinding speeds and regulating the tension of the fabric 002 to achieve constant tension unwinding and winding, avoiding defects such as interlayer slippage, wrinkles, and misalignment caused by tension fluctuations or sudden speed changes. Furthermore, the fabric unloading device may also include a tension roller, which is movably connected to the base 100. The tension roller is used to abut against the fabric 002 and adjust the tension (or tautness) of the fabric 002. Due to the requirements of tube making, the fabric 002 needs a certain tautness, but the tautness cannot be too large. Therefore, a tension roller can be set up for adjustment. For specific technical details of the tension roller, please refer to the existing technical content. It should be understood that other components on the equipment may also provide a certain backward movement force to the material, such as the pressing roller group 510 and the glue coating roller, which can drive the material backward through friction. Combined with the active unwinding of the fabric roll, the pulling force of the inner lining 003 on the fabric 002 will not be too large.

[0048] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the first clamping mechanism 1010 includes a first upper clamping plate 1011, a first lower clamping plate 1012 and an elastic sheet 1013, and the first upper clamping plate 1011 and the first lower clamping plate 1012 are both connected to the first driving mechanism.

[0049] In this embodiment, specifically, one end of the elastic sheet 1013 is connected to the side of the first lower clamping plate 1012 near the winding device 1100, and the other end of the elastic sheet 1013 extends towards the winding device 1100; the first driving mechanism is used to drive the first upper clamping plate 1011 and the first lower clamping plate 1012 to move closer or further apart from each other, thereby clamping or releasing the fabric 002. The clamping area of ​​the clamping plates is relatively large, so when clamping the fabric 002, the fabric 002 is subjected to more uniform force, which can prevent the fabric 002 from wrinkling. The clamping plates are generally plate-shaped structures. It should be understood that the plate-shaped structure in this utility model is not necessarily a completely flat structure. It may have depressions, protrusions, and openings; and it is not necessarily a flat state, but may have certain bends or curves; and it may be a single plate or it may be composed of multiple other components connected together. In some embodiments, the drive mechanism may specifically include two cylinders, one clamping plate fixed and the other cylinder fixed on the fixed base. This cylinder is connected to the other clamping plate, thereby driving the clamping plate to move closer to or away from the other clamping plate, thereby clamping or releasing the fabric 002. The other cylinder is connected to the fixed base (this cylinder itself is fixed on the base 100), thereby driving the fixed base and the cylinders and clamping plates (and the fabric 002 that may be clamped) to move closer to or towards the raw material winding device 1100.The elastic sheet 1013 is a sheet-like structure with elasticity. After the previous bamboo tube is manufactured and the fabric 002 is cut, the remaining fabric 002 (the fabric 002 away from the winding device 1100) will droop down under gravity. When manufacturing the next bamboo tube, the fabric 002 needs to be attached and fixed to the inner lining 003 of the next bamboo tube (the first drive mechanism drives the clamping plate, and the fabric 002 approaches the winding device 1100). Generally, one end of the fabric 002 is glued to the inner lining 003. However, if the elastic sheet 1013 is not provided, the drooping fabric 002 will stick to the side wall of the first lower clamping plate 1012 (near the winding device 1100). First, the fabric 002 is easy to get tangled on the clamping plate. Second, in order to make the connection between one end of the fabric 002 and the inner lining 003 firm, it is usually necessary to use a large force to press the drooping fabric 002 tightly against the inner lining 003. Without the elastic sheet 1013, the greater force can easily cause the inner lining 003 to shift or even deform, affecting the quality of the bamboo tubes formed later. In fact, if the positioning of the first lower clamping plate 1012 or the inner lining 003 is not accurate, the two rigid bodies of the first lower clamping plate 1012 and the inner lining 003 may squeeze and collide, which can easily damage the first clamping mechanism 1010 and the winding device 1100, causing equipment damage. However, by setting the elastic sheet 1013, the drooping fabric 002 will stick to the elastic sheet 1013. When the first driving mechanism presses the fabric 002 onto the inner lining 003, the elastic sheet 1013 is elastic and can deform to absorb the impact force and buffer the pressure, preventing the inner lining 003 from shifting or deforming and causing equipment damage. Moreover, the deformed elastic sheet 1013 can fit the inner lining 003 better, so that the fabric 002 on the elastic sheet 1013 fits the inner lining 003 better, resulting in a better fixing effect.

[0050] It should be understood that "near" and "far away" in this utility model are relative positional relationships, not specific distances; the position of "A near B" is relative to the position of A far away from B, and does not refer to how close A and B are in terms of specific distance.

[0051] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the bamboo tube manufacturing equipment further includes a second gluing device 800, which is disposed on the base 100. The first gluing device 600 is used to apply glue to the upper surface of the bamboo skin 001, and the second gluing device 800 is used to apply glue to the lower surface of the fabric 002. The second gluing device 800 is located between the cutting mechanism (second lower clamping plate 1022) and the winding device 1100.

[0052] In order to make the bamboo skin 001 and the fabric 002 more securely and tightly wrapped on the lining 003, a first gluing device 600 is set to apply glue to the upper surface of the bamboo skin 001 and a second gluing device 800 is set to apply glue to the lower surface of the fabric 002. This facilitates the bonding between the lower surface (or outer surface) of the fabric 002 that has already been wrapped on the lining 003 and the upper surface (or inner surface) of the bamboo skin 001 that will be wrapped on the lining 003. Since the second gluing device 800 needs to apply glue to the lower surface of the fabric 002, if the glue is applied to the lower surface of the fabric 002 too early, the fabric 002 is likely to adhere to the equipment components below it during movement, affecting the movement of the fabric 002. In addition, the glue on the lower surface of the fabric 002 is likely to rub against the equipment components below the fabric 002, which will not only contaminate the equipment, but also make it easy to have insufficient glue on the lower surface of the fabric 002. Therefore, the second gluing device 800 is generally located close to the winding device 1100. In this embodiment, the second gluing device 800 is located between the cutting mechanism and the winding device 1100. In some embodiments, the gluing device can employ existing roller coating technology. Specifically, it includes a gluing roller and a glue storage roller, with glue stored in the gap between them. The gluing roller rotates, adsorbing the glue in the gap onto its outer surface. It then continues to rotate, coating the glue on its outer surface onto the bamboo skin 001 and the fabric 002. Furthermore, it can be equipped with a glue quantity adjustment handwheel, a roller coating sliding block, a roller coating sliding frame, and an adjustment rod. The roller coating sliding frame is mounted on the base 100, and the roller coating sliding block is slidably connected to the roller coating sliding frame. One end of the adjustment rod passes through the roller coating sliding frame and is connected to the roller coating sliding block, while the other end of the adjustment rod is connected to the glue quantity adjustment handwheel. The adjustment rod and the roller coating sliding frame are threaded together. By rotating the handwheel, the adjustment rod can be rotated, thereby causing the roller coating sliding block to slide, thus adjusting the distance between the gluing roller and the glue storage roller, and ultimately adjusting the glue quantity for easy control of the gluing amount.

[0053] It's important to understand that the distinction between inside and outside refers to the difference between the inside and outside of the bamboo skin 001 and the center of the inner lining 003 after they are wrapped around it. Specifically, the distinction between the inner and outer surfaces refers to the difference between the two surfaces of the bamboo skin 001 and the center of the inner lining 003 after they are wrapped around it. Similarly, the circumferential, radial, and axial directions of the bamboo skin 001 and the fabric 002 are also relative to the tubular inner lining 003 after they are wrapped around it. It's crucial to understand that in the manufacturing of bamboo-wound pipes, generally, the bamboo skin 001 and fabric 002 (in the same layer) wrapped around the inner lining 003 should have the bamboo skin 001 inside and the fabric 002 outside. This facilitates the wrapping and compaction of the bamboo skin 001 during winding. If the bamboo skin 001 is outside, the sides of the bamboo skin 001 (circumferentially both sides) are prone to curling up after winding, making it easy to bend, roll up, overlap, and bulge during subsequent winding, affecting the quality of the bamboo tube, especially the inner lining 001. When the diameter of bamboo 003 is small and the width (circumferential direction) of bamboo 001 is long, bamboo 001 is more likely to curl up, and may even separate from the fabric 002 and fall off completely. It is also more likely to come into contact with the baking device (the baking device needs to be close enough to the inner lining 003 for convenient heat transfer during baking). Furthermore, bamboo 001 is usually placed on the fabric 002 and moved by the fabric 002. However, if bamboo 001 is placed under the fabric 002 (the bamboo 001 adhesive...), If the bamboo skin 001 is attached to the lower surface of the fabric 002, it is easy for it to fall off due to gravity. Furthermore, taking the rotating axis of the inner lining 003 (or the rotating axis of the inner lining 003 driven by the winding device 1100) as the reference axis and the plane perpendicular to the reference axis as the reference plane, during the winding tube making operation, the projections of the winding device 1100 (inner lining 003) and the fabric 002 onto the reference plane are generally as follows: the fabric 002 extends from the lower half of the inner lining 003. When the fabric 002 (including the feeding device 200, the fabric feeding device, the cutting mechanism, the clamping mechanism, etc.) on the projection surface is wound around the inner lining 003, from the perspective of the observer's specific viewing position, if the observer sees the fabric 002 on the projection surface to the left of the reference axis, then the inner lining 003 generally rotates clockwise (if the fabric 002 is to the left of the reference axis, then the inner lining 003 generally rotates counterclockwise). These are the inevitable limitations brought about by the fact that 'the bamboo skin 001 is on top and inside, and the fabric 002 is on the bottom and outside'.

[0054] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the bamboo tube manufacturing equipment also includes an adhesive application moving device, which is mounted on the base 100 and connected to the second adhesive application device 800 (the second adhesive application device 800 is no longer directly connected to the base 100). The adhesive application moving device can drive the second adhesive application device 800 to move closer to or further away from the winding device 1100.

[0055] At the beginning of bamboo tube manufacturing (or before manufacturing), to ensure that the fabric 002 can be securely fixed to the lining 003, glue is usually applied to the outer surface of the lining 003. This usually requires manual glue application or the use of a separate glue application device, which is wasteful of manpower and involves complex and repetitive structures. However, by setting up a glue application moving device, the second glue application device 800 can be moved closer to the winding device 1100 at the beginning of bamboo tube manufacturing to pre-apply glue to the lining 003. Then, it can move away from the winding device 1100 and return to its original position to prepare for applying glue to the lower surface of the fabric 002. One device achieves two purposes, making it simpler and more convenient. Furthermore, before the glue application moving device moves the second glue application device 800 back to its original position, and after the fabric 002 is cut, it can be moved and stopped below (directly below or diagonally below) its original position, providing space for the first clamping mechanism 1010 to move the fabric 002, facilitating... (Driven by the first driving mechanism) The first clamping mechanism 1010 drives the fabric 002 close to the winding device 1100, and glues the fabric 002 to the inner lining 003. Furthermore, since the fabric 002 is finally wrapped around the inner lining 003, the outermost layer of the bamboo tube is the lower surface of the fabric 002. Therefore, the lower surface of the outermost layer of the wrapped fabric 002 does not need to be coated with glue. Thus, at the end of the bamboo tube manufacturing process, before cutting the fabric 002, the gluing moving device can move the second gluing device 800 to stop below its original position, so that the second gluing device 800 does not apply glue to the lower surface of the fabric 002 at the end (at this time, the fabric 002 is supported by the second lower clamping plate 1022 or other parts or is suspended). This saves glue and prevents the outer surface of the bamboo tube from having glue after it is formed, which is easy to get dusty and makes the bamboo tube easy to stick to other objects (such as other bamboo tubes or transportation equipment), which is not conducive to the transportation and storage of the bamboo tube. The specific structure and working principle of the gluing moving device can refer to the aforementioned drive mechanism. For example, it can be set up with multiple sets of cylinders or other drive components to drive the movement. Alternatively, it can be set up with a structure similar to a multi-joint robotic arm. Or, it can refer to the setting of the material conveying device and be set up with a guide rail slider. It can also be a combination of the above methods or other implementation methods in the prior art. For example, the second gluing device 800 is a roller coating device with both ends mounted on the mounting platform. Cylinders or other drive components drive the mounting platform to move up and down, thereby driving the second gluing device 800 to move up and down. The drive component is mounted on the moving platform, and the moving platform is slidably connected to the sliding rail. Another drive component drives the moving platform to move back and forth, thereby driving the second gluing device 800 to move back and forth.

[0056] It is important to understand that at the end of the bamboo tube manufacturing process, the bamboo skin 001 is usually no longer placed on the end of the cloth 002. This cloth 002 without bamboo skin 001 is wrapped around the inner lining 003 at the end of the bamboo tube manufacturing process, so that the outermost layers of the finished bamboo tube are a structure made entirely of cloth 002, which facilitates pressing and securing the entire bamboo tube. At the beginning of the bamboo tube manufacturing process, the bamboo skin 001 is also usually no longer placed on the beginning of the cloth 002. This cloth 002 without bamboo skin 001 is wrapped around the initial inner lining 003 several times (two, three, or more times), so that the innermost layers of the finished bamboo tube (excluding the inner lining 003) are a structure made entirely of cloth 002, which facilitates the gluing and fixing of the bamboo skin 001. Therefore, the cutting mechanism generally cuts pure cloth 002, excluding bamboo skin 001.

[0057] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the feeding device 200 includes a feeding platform 210, a lifting mechanism 220 and a first material conveying sensor. The lifting mechanism 220 is mounted on the base 100 and connected to the feeding platform 210. The first material conveying sensor is electrically connected to the lifting mechanism 220. The feeding platform 210 is used to place bamboo skin 001. The first material conveying sensor is used to measure the height of the bamboo skin 001 placed on the feeding platform 210. The lifting mechanism 220 is used to control the height of the feeding platform 210.

[0058] The first material handling sensor can be set on the base 100, or on the feeding platform 210 or the lifting mechanism 220. The first material handling sensor measures the height of the bamboo skin 001 and transmits the height data of the bamboo skin 001 to the lifting mechanism 220. The lifting mechanism 220 raises (when the bamboo skin 001 is taken away by the first material handling device 300) or lowers (when some new bamboo skin 001 is added to the feeding platform 210) the height of the feeding platform 210 according to the height data of the bamboo skin 001, so that the height of the top bamboo skin 001 on the feeding platform 210 is always in a suitable range, which is convenient for the first material handling device 300 to pick up. In particular, when the first material handling device 300 uses a suction cup 310, it can keep the suction cup 310 and the upper surface of the top bamboo skin 001 at all times, and prevent over-suction and under-suction. It should be understood that the technology of sensor measuring height and the technology of lifting mechanism 220 lifting and lowering material platform 210 according to bamboo skin 001 height data can both be achieved using existing technologies (such as ultrasonic sensors and scissor lifts), so their specific structures and principles will not be elaborated here; the same applies to the technologies of other subsequent drive mechanisms for driving component movement, gluing, baking and other applications.

[0059] Reference Figure 1 , Figure 2 and Figure 3In some embodiments of this utility model, the first material conveying device 300 includes a suction cup 310, a movable guide rail 320, a mounting base 330, and a first material conveying drive mechanism. The movable guide rail 320 is disposed on the base 100, and the mounting base 330 and the movable guide rail 320 are slidably connected. The first material conveying drive mechanism is connected to the mounting base 330 and can drive the mounting base 330 to slide relative to the movable guide rail 320. The suction cup 310 is disposed on the mounting base 330.

[0060] The first material conveying drive mechanism drives the mounting base 330, carrying the suction cup 310, to slide along the moving guide rail 320 above the material dispensing device 200. The suction cup 310 adsorbs and fixes the bamboo skin 001. The first material conveying drive mechanism then drives the mounting base 330, carrying the suction cup 310 and the bamboo skin 001 adsorbed and fixed thereon, to slide along the moving guide rail 320 above the fabric 002 (positioning table 410). The suction cup 310 then lowers the bamboo skin 001. It should be understood that the suction cup 310 can be a component with its own adsorption structure, or it can be an air suction cup 310, with adsorption control via an external air passage. The first material conveying drive mechanism can include a servo motor for more precise, stable, and rapid operation. It is important to understand that in the specific bamboo tube manufacturing process, when feeding materials, at the beginning of manufacturing a new bamboo tube, there will be a period of time during which bamboo skin 001 will not be added (the first material conveying device 300 stops conveying bamboo skin 001), so that a section of pure cloth 002 without bamboo skin 001 is wrapped around the inner lining 003, and the innermost layers of the bamboo tube are composed entirely of cloth 002 (ignoring the inner lining 003); when the manufacturing of a bamboo tube is about to be completed, there will also be a period of time during which bamboo skin 001 will not be added, so that a section of pure cloth 002 without bamboo skin 001 is wrapped around the inner lining 003, and the outermost layers of the bamboo tube are composed entirely of cloth 002; furthermore, the first material conveying device 300 can be set to convey a fixed number of times (convey a fixed number of bamboo skins 001, or in other words, the bamboo tube is manufactured using a fixed number of bamboo skins 001, which facilitates the quality control of the bamboo tube) and then stop for a fixed period of time.

[0061] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the bamboo tube manufacturing equipment further includes a second material conveying device 400. The second material conveying device 400 includes a positioning platform 410, a positioning baffle, a conveyor belt, and a second material conveying drive mechanism. The positioning platform 410 is disposed on the base 100. A positioning baffle is disposed on each of the left and right sides of the upper surface of the positioning platform 410. The conveyor belt is disposed on the positioning platform 410 between the two positioning baffles. The second material conveying drive mechanism is connected to the conveyor belt.

[0062] The second material conveying drive mechanism drives the conveyor belt, and the first material conveying device 300 can transport the bamboo skin 001 onto the conveyor belt. The left and right sides of the bamboo skin 001 are positioned and limited by positioning baffles, which can play a certain positioning role for the bamboo skin 001 and ensure the perpendicularity of the bamboo skin 001 (the length extension direction of the bamboo skin 001 is perpendicular to the conveying direction of the bamboo skin 001). Specifically, when one side of the bamboo skin 001 is excessively skewed, that side protrudes and is likely to touch the positioning baffle, and be blocked by the positioning baffle to prevent the excessively skewed bamboo skin 001 from wrapping around the inner lining 003 to form a bamboo tube and becoming a defective product. The equipment can stop in time (by detecting the situation through sensors) to facilitate subsequent correction. After the first material conveying device 300 transports the bamboo skin 001 onto the conveyor belt, the conveyor belt continues to move the bamboo skin 001, transporting it to the next stage (on the fabric 002 or other devices). The positioning baffle can be made of steel bars, L-shaped angle steel, or defined by the equipment itself (a protrusion or relatively protruding structure of the equipment itself).

[0063] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the bamboo tube manufacturing equipment further includes a third material conveying device 500. The third material conveying device 500 includes a pressing roller group 510 and a third material conveying drive mechanism. The pressing roller group 510 includes two pressing rollers 511 arranged vertically opposite each other. Both pressing rollers 511 are rotatably connected to the base 100. The third material conveying drive mechanism is connected to at least one pressing roller 511.

[0064] It is important to understand that multiple pressing roller groups 510 can be provided, and a third material conveying drive mechanism is connected to at least one pressing roller 511 in each pressing roller group 510. The distance between two pressing roller groups 510 should not be too large, generally less than the width of the bamboo skin 001, so that the bamboo skin 001 conveyed by the previous pressing roller group 510 can be received by the next pressing roller group 510. The third material conveying drive mechanism can drive the pressing roller 511 connected to it to rotate relative to the base 100. The previous material conveying mechanism transports the bamboo skin 001, so that the bamboo skin 001 enters between the two pressing rollers 511 of the pressing roller group 510. The gap between the two pressing rollers 511 is small, which can both press the material and, through friction (interference fit), drive the material to continue moving backward during rotation. It is important to understand that multiple pressing roller groups 510 can be provided, such as two. The first pressing roller group 510, located at the front, is used to press the bamboo skin 001, making the bamboo skin 001 flatter and tighter. The second pressing roller group 510, located at the rear, is used to pass the fabric 002 between the two pressing rollers 511 of the second pressing roller group 510. When the bamboo skin 001 enters the middle of the second pressing roller group 510, it not only transports the bamboo skin 001 onto the fabric 002, allowing the subsequent bamboo skin 001 to be driven and transported by the fabric 002, but also initially presses the fabric 002 and the bamboo skin 001 together, so that the bamboo skin 001 is relatively fixed on the fabric 002, preventing the bamboo skin 001 from moving back and forth on the fabric 002, which would result in excessive overlap and compression with the bamboo skin 001 in front, and a large blank area without bamboo skin 001 exposed behind, affecting the quality of bamboo tube forming. It should be understood that the direction in which bamboo skin 001 and cloth 002 are normally conveyed and moved is the front-back direction, and the direction in which bamboo skin 001 and cloth 002 are normally conveyed and moved is the back direction.

[0065] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the bamboo tube manufacturing equipment further includes a third gluing device, which is disposed on the base 100 and is used to apply glue to the lower surface of the bamboo skin 001 and / or the upper surface of the fabric 002.

[0066] The equipment includes a first gluing device 600, a second gluing device 800, and a third gluing device, all of which are mounted on a base 100. The first gluing device 600 applies glue to the upper surface of the bamboo veneer 001. When the bamboo veneer 001 is wound onto the inner lining 003, the upper surface of the bamboo veneer 001 can be glued to the outer surface of the existing material on the inner lining 003. The second gluing device 800 applies glue to the lower surface of the fabric 002. When the fabric 002 is wound onto the inner lining 003, the lower surface (or outer surface) of the fabric 002 can be glued to the inner surface of the subsequently wound material. The third gluing device is used to apply glue to the lower surface of bamboo skin 001 and / or the upper surface of fabric 002, thereby facilitating the bonding between bamboo skin 001 and fabric 002. The resulting bamboo tube is more compact and firm, and prevents relative movement between bamboo skin 001 and fabric 002 during material transport, which could lead to excessive overlap and compression with the preceding bamboo skin 001, and expose a large blank area without bamboo skin 001, affecting the quality of bamboo tube forming. It should be understood that after the third gluing device applies glue to the material, it can be further pressed by the pressing roller group 510, making the bond between bamboo skin 001 and fabric 002 more compact and firm, and making the glue distribution more uniform, preventing excessive accumulation of glue in a certain area, which could cause undesirable protrusions. It should be understood that the third gluing device needs to be installed before the bamboo skin 001 and fabric 002 are bonded (or, before the bamboo skin 001 is transported onto the fabric 002).

[0067] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the bamboo tube manufacturing equipment further includes a first baking device 700, which is disposed on the base 100 and located between the first gluing device 600 and the winding device 1100.

[0068] Setting up a baking device can accelerate the evaporation of the diluent remaining in the silicone adhesive and reduce the viscosity of the adhesive layer, forming a micro-cured layer on the surface. This avoids adhesive layer defects caused by solvent bubbles during subsequent hot pressing, while retaining sufficient active groups to improve the bonding strength. The specific implementation technology of the baking device can refer to the existing technology. Specifically, in some embodiments, a short-wave infrared radiator can be used for thermal radiation baking, and a fan can be equipped to transfer heat and blow away volatile substances, achieving an efficient, uniform, and controllable pre-baking effect. It should be understood that since there are multiple gluing devices, there can be multiple baking devices accordingly (the first gluing device 600 applies glue to the surface of the bamboo skin 001, so the first baking device 700 is mainly used to bake the upper surface of the bamboo skin 001, and can also bake the adhesive layer that combines the bamboo skin 001 and the fabric 002). For example, a second baking device 900 can be additionally provided. The second baking device 900 is set on the base 100 and is located near the winding device 1100 (the second baking device 900 is located above the inner lining 003 and is mainly used to bake the lower (outer) surface of the fabric 002).

[0069] Reference Figure 1 , Figure 2 and Figure 3 In some embodiments of this utility model, the cutting device 1000 includes a cutting mechanism, a first clamping mechanism 1010 and a first driving mechanism. The cutting mechanism is used to cut the fabric 002. The first driving mechanism is connected to the first clamping mechanism 1010. The first driving mechanism can drive the first clamping mechanism 1010 to clamp or release the fabric 002. The first driving mechanism can also drive the first clamping mechanism 1010 to move closer to or away from the winding device 1100.

[0070] After the first clamping mechanism 1010 clamps the fabric 002, the cutting mechanism cuts the fabric 002 between the first clamping mechanism 1010 and the winding device 1100. Then, the first driving mechanism drives the first clamping mechanism 1010 to approach the winding device 1100, and fixes the fabric 002 to the lining 003. This is precise and stable, and no longer requires manual dragging, which is more convenient, saves manpower, and avoids danger to personnel.

[0071] The cutting mechanism is a mechanism that can cut the fabric 002 and even the bamboo skin 001. The specific cutting methods can be knife cutting, shearing, laser cutting, wire cutting, saw blade cutting, etc. When the bamboo tube is about to be finished winding, the cutting device 1000 can cut the fabric 002 (and the bamboo skin 001 that may be contained therein) and wait for the next bamboo tube to be manufactured, and then reconnect the fabric 002 to the inner lining 003 of the next bamboo tube. More specifically, in some embodiments, the first upper clamping plate 1011 is provided with a slide rail on the side near the winding device 1100. The cutting mechanism includes a cutting wheel and a sliding seat. The cutting wheel is rotatably connected to the sliding seat, and the sliding seat and the slide rail are slidably connected, so that the cutting wheel can be driven to cut the fabric 002. The cutting wheel can be electrically driven to rotate, or it can be cut by the sharpness of its own blade.

[0072] The driving mechanism is the mechanism that drives the clamping mechanism to clamp and / or move. It should be understood that the first clamping mechanism 1010 can approach or move away from the winding device 1100 in a straight line, or in a curve, a broken line, or a combination thereof. The same principle applies to the driving movement methods used in other structures of this invention. It should be understood that the driving component (such as the driving mechanism or driving assembly) and the driven component (such as the clamping mechanism or clamping plate) mentioned in this invention are connected. The driving component can be directly connected to the driven component, directly driving the movement of the driven component. Alternatively, the driving component can be connected to the driven component through an intermediate transmission assembly (such as a rope, long rod, gear, rack, belt, chain, lead screw nut, magnetic block, or one or more reused or combined components). The components are indirectly connected, thereby changing the speed, direction, magnitude, range, start time, total duration, number of actions, and position of the driving force applied to the driven component. Furthermore, since the first driving mechanism in this invention must both drive the first clamping mechanism 1010 to clamp or release the fabric 002 and move it closer to or away from the winding device 1100, the first driving mechanism can be a single driving source, achieving two actions through an intermediate transmission component. Alternatively, the first driving mechanism can contain two driving sources, with one driving source corresponding to one action. It should be understood that the driving source of various driving mechanisms (or other power components) in this invention can be a cylinder, hydraulic cylinder, electric cylinder, motor, engine, or a combination thereof. It should be understood that "closer or farther" in "A drives B closer to or farther from C" means that A drives B relatively closer to C during a certain period and drives B relatively farther from C during another period. That is, the word "or" here means that A performs different actions at different times, not that A can only perform one of two actions. The terms "clamping or releasing" and similar terms used in other parts of this utility model shall also be understood in accordance with this clause.

[0073] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
