[0020] In the description of the present invention, unless otherwise clearly defined, words such as setting, installation, connection, etc. should be understood in a broad sense. Those skilled in the art can reasonably determine the specific meaning of the above words in the present invention in combination with the specific content of the technical solution.

[0021] Refer to Figures 1 to 3, A pipe coiling machine according to an embodiment of the present invention, the pipe coiling machine includes a frame 10, a guiding device 20 and a winding device 30. The guiding device 20 is arranged on the frame 10, and the guiding device 20 is configured to tension the nylon hose during the conveying process; the winding device 30 is rotatably arranged on the frame 10 through a rotating shaft 34. The winding device 30 is located on one side of the guiding device 20, and the winding device 30 is configured to wind the nylon hose. The winding device 30 includes a first limiting plate 31, a winding assembly 32 and a limiting assembly 33. The first limiting plate 31 can be sleeved on the rotating shaft 34, and the limiting assembly 33 is detachably arranged at one end of the winding assembly 32. The other end of the winding assembly 32 is arranged at one end of the rotating shaft 34. The outer shape of the winding assembly 32 is adjustable. The winding assembly 32 is located between the first limiting plate 31 and the limiting assembly 33, and the winding assembly 32 is configured to wind the nylon hose.

[0022] The pipe coiling machine of the present invention effectively solves the technical problem of over-tight winding of the nylon hose during the winding process through the guiding device 20 and the winding device 30. The guiding device 20 can ensure that the nylon hose maintains an appropriate tension state during the conveying process, avoiding the hose from being slack due to insufficient tension or being stretched and deformed due to excessive tension. The cooperation of the first limiting plate 31, the winding assembly 32 and the limiting assembly 33 in the winding device 30 not only realizes the orderly winding of the hose, but also facilitates the blanking requirement after the winding work through the adjustable outer shape of the winding assembly 32. Especially the detachable design of the limiting assembly 33 enables the wound hose to be easily removed from the winding assembly 32 after winding.

[0023] Specifically, the pipe coiling machine includes a stable frame 10, which serves as the support structure for the entire device. A guiding device 20 is provided on the frame 10. The guiding device 20 can adopt structures such as rollers or cylinders. By adjusting the distance and position between the rollers or the pressure of the cylinder, the guiding and tension control of the nylon hose can be achieved. The guiding device 20 ensures that the hose maintains a stable conveying direction and appropriate tension when being conveyed to the winding device 30. The winding device 30 is located on one side (the right side in the figure) of the guiding device 20 and is rotatably arranged on the frame 10 through a rotating shaft 34 (the front side of the frame 10 shown in the figure). The winding device 30 includes a first limiting plate 31, a winding assembly 32, and a limiting assembly 33. The first limiting plate 31 can be sleeved on the rotating shaft 34, playing a role in initially limiting the winding position of the hose. The winding assembly 32 is the core part of the winding device 30, and its shape can be adjusted according to the needs of material feeding to facilitate the removal of the wound nylon hose from the winding assembly 32. One end of the winding assembly 32 is arranged at one end of the rotating shaft 34 (the front side shown in the figure), and the other end is connected to the limiting assembly 33. The limiting assembly 33 adopts a detachable design, such as being connected to one end of the winding assembly 32 through connection methods such as bolts and buckles. During the winding process, the limiting assembly 33 and the first limiting plate 31 cooperate together to restrict the nylon hose on the surface of the winding assembly 32 for orderly winding. When the winding is completed, the operator only needs to simply disassemble the limiting assembly 33 to easily remove the wound hose from the winding assembly 32.

[0024] Therefore, it can be understood that a pipe coiling machine according to an embodiment of the present invention has at least the following beneficial effects: The winding device 30 winds the nylon hose on the outside of the winding assembly 32, and then the shape of the winding assembly 32 can be adjusted to make its shape smaller, so as to facilitate the removal of the wound nylon hose from the winding assembly 32, which is beneficial to the production and processing of the nylon hose.

[0025] Refer to Figures 2 to 4 , in some embodiments of the present invention, the winding assembly 32 includes a fixed part 321, a first movable part 322, and a second movable part 323. One end of the fixed part 321 is arranged at one end of the rotating shaft 34; one side end of the first movable part 322 is hinged to one side end of the fixed part 321, and the first movable part 322 can rotate around the hinge point; the side end of the second movable part 323 is hinged to the other side end of the fixed part 321, and the second movable part 323 can rotate around the hinge point. A winding roller is defined between the first movable part 322, the second movable part 323, and the fixed part 321. The other side end of the first movable part 322 and the other side end of the second movable part 323 are configured to be able to move away from or close to each other through an adjusting component 40 to adjust the shape of the winding roller. The adjusting component 40 is detachably connected to the limiting assembly 33.

[0026] In the coiling machine of the present invention, the coiling assembly 32 realizes the adjustability of the outer shape of the coiling roller to meet the coiling and discharging requirements of the nylon hose. Specifically, the coiling assembly 32 includes a fixed part 321, a first movable part 322, and a second movable part 323. One end of the fixed part 321 is firmly arranged at one end of the rotating shaft 34, serving as the basic support of the coiling assembly 32. One side end of the first movable part 322 is connected to one side end of the fixed part 321 by a hinge, enabling the first movable part 322 to rotate around the hinge point as the axis. Similarly, the side end of the second movable part 323 is also hinged to the other side end of the fixed part 321 to realize the rotation function of the second movable part 323. Therefore, the other side ends of the first movable part 322 and the second movable part 323 can move away from or approach each other (i.e., away from or close to the axis of the rotating shaft 34) during the process of slightly opening or closing.

[0027] The first movable part 322, the second movable part 323, and the fixed part 321 cooperate with each other to define the structure of a coiling roller. To adjust the outer shape of the coiling roller, an adjusting assembly 40 is provided between the other side ends of the first movable part 322 and the second movable part 323 in an embodiment of the present invention. The adjusting assembly 40 can make the first movable part 322 and the second movable part 323 move away from or approach each other, so that the first movable part 322 and the second movable part 323 can slightly open or close around the hinge point as the axis, thereby changing the outer shape size of the coiling roller. When it is necessary to coil the nylon hose, the first movable part 322 and the second movable part 323 are made to move away from each other through the adjusting assembly 40, causing a part of the structure of the coiling roller to slightly open, thereby slightly increasing the outer shape of the coiling roller; conversely, when it is necessary to unload the nylon hose, the two are made to approach each other, causing the opened part of the coiling roller to close, thereby reducing the outer shape of the coiling roller.

[0028] In addition, a detachable connection method is adopted between the adjusting assembly 40 and the limiting assembly 33. This design not only facilitates the assembly and disassembly of the coiling assembly 32, but also enables the limiting assembly 33 to be easily removed from the coiling assembly 32 together with the coiled hose after coiling, further improving the operation convenience and efficiency.

[0029] Refer to Figures 3 to 5, in some embodiments of the present invention, the adjusting assembly 40 is disposed inside the winding assembly 32. The adjusting assembly 40 includes a driving shaft 41, a first abutting roller 42, a second abutting roller 44, and a second elastic reset member 45. One end of the driving shaft 41 is rotatably disposed on the rotating shaft 34. A driving cam 46 is sleeved on the driving shaft 41, and the driving cam 46 rotates synchronously with the driving shaft 41. The first abutting roller 42 is rotatably disposed inside the first movable portion 322 through a first support 421. The circumferential side of the first abutting roller 42 can abut against the circumferential side of the driving cam 46, and the first abutting roller 42 can roll relative to the driving cam 46. The second abutting roller 44 is rotatably disposed inside the second movable portion 323 through a second support 441. The second abutting roller 44 is located on one side of the first abutting roller 42. The circumferential side of the second abutting roller 44 can abut against the circumferential side of the driving cam 46, and the second abutting roller 44 can roll relative to the driving cam 46. The second elastic reset member 45 is disposed between the first movable portion 322 and the second movable portion 323. One end of the second elastic reset member 45 is connected to the inside of the first movable portion 322, and the other end of the second elastic reset member 45 is connected to the inside of the second movable portion 323.

[0030] An adjusting assembly 40 is provided inside the winding assembly 32 of the pipe winding machine of the present invention to flexibly adjust the shape of the winding roller. The core components of the adjusting assembly 40 include a driving shaft 41, a driving cam 46, a first abutting roller 42, a second abutting roller 44, and a second elastic reset member 45.

[0031] One end of the driving shaft 41 is rotatably disposed on the rotating shaft 34, ensuring its relative independent rotation with the rotating shaft 34. A driving cam 46 is sleeved and connected to the driving shaft 41, and the driving cam 46 and the driving shaft 41 rotate synchronously. The design of the driving cam 46 makes its circumferential surface have different radii, so that different thrusts can be generated on the rollers abutting thereon during rotation. The first abutting roller 42 is rotatably disposed inside the first movable portion 322 through a first support 421. The circumferential side of the first abutting roller 42 can abut against the circumferential side of the driving cam 46 and roll relative to the driving cam 46 as the driving cam 46 rotates. Similarly, the second abutting roller 44 is disposed inside the second movable portion 323 through a second support 441, located on one side of the first abutting roller 42. The circumferential side of the second abutting roller 44 can also abut against the circumferential side of the driving cam 46 and roll relative to it.

[0032] When the driving cam 46 rotates, different radius portions of its circumferential surface will respectively push the first abutting roller 42 and the second abutting roller 44, causing the first movable portion 322 and the second movable portion 323 to slightly open or close relative to the fixed portion 321, thereby changing the shape of the winding roller. It should be emphasized that in order to maintain the relative position stability of the first movable portion 322 and the second movable portion 323 when no external force is applied, the contour line of the driving cam 46 can be designed as an Archimedean spiral. Thus, through the self-locking property of the Archimedean spiral of the driving cam 46, the position of the driving cam 46 can be fixed after the external force is lost, thereby preventing the first movable portion 322 and the second movable portion 323 from closing towards the axis of the winding roller relative to the fixed portion 321 during the winding process. A second elastic reset member 45 is provided between them. One end of the second elastic reset member 45 is connected to the inner side of the first movable portion 322, and the other end is connected to the inner side of the second movable portion 323, ensuring that after the winding is completed, when the driving shaft 41 rotates back, the first movable portion 322 and the second movable portion 323 can return to the closed state, facilitating the removal of the wound nylon hose. In some embodiments, the second elastic reset member 45 can be a spring, an elastic rubber member, etc., and is not specifically limited in this embodiment.

[0033] Referring to Figures 3 to 5 , in some embodiments of the present invention, the driving cam 46 includes a first cam 461 and a second cam 462. The first cam 461 is disposed at one end of the second cam 462. The first cam 461 and the first abutting roller 42 are in mutual abutment, and the second cam 462 and the second abutting roller 44 are in mutual abutment.

[0034] In the adjusting assembly 40 of the coiling machine of the present invention, the driving cam 46 is designed with a double-cam structure, namely a first cam 461 and a second cam 462. The second cam 462 is directly sleeved on the other end of the driving shaft 41 and rotates synchronously with the driving shaft 41. The first cam 461 is further arranged at one end of the second cam 462 and is also sleeved on the driving shaft 41. Thus, when the driving shaft 41 rotates, it will drive the second cam 462 and the first cam 461 to rotate simultaneously. The first cam 461 and the first abutting roller 42 are in mutual abutment, and the second cam 462 and the second abutting roller 44 are in mutual abutment. This design enables the first cam 461 and the second cam 462 to respectively exert a pushing effect on their corresponding abutting rollers when the driving cam 46 rotates. Since the shapes and contours of the first cam 461 and the second cam 462 can be designed as required, they can generate different thrusts on the abutting rollers during rotation, thereby driving the first movable part 322 and the second movable part 323 to slightly open or close relative to the fixed part 321. Through this double-cam design, the shape of the winding roller can be adjusted more flexibly to slightly open or close it. At the same time, since the first cam 461 and the second cam 462 are respectively in mutual abutment with the first abutting roller 42 and the second abutting roller 44, the self-locking properties of the two cams ensure the stability and reliability of the adjustment process. During actual use, the operator only needs to control the rotation of the driving shaft 41 to easily rotate the driving cam 46 structure, so that the first movable part 322 and the second movable part 323 can quickly open slightly or quickly close and reset to adjust the shape of the winding roller.

[0035] Referring to Figures 3 to 5 , in some embodiments of the present invention, a positioning post 3211 is provided at one end of the fixed part 321. The limiting assembly 33 includes a mounting base 331 and a second limiting plate 332. The second limiting plate 332 is detachably arranged at one end of the winding assembly 32 through the mounting base 331. The mounting base 331 is provided with a limiting hole 3311, and the limiting hole 3311 can be sleeved on the positioning post 3211.

[0036] Specifically, a positioning post 3211 is provided at one end of the fixing part 321, and this positioning post 3211 will play a key role in subsequent assembly. The limiting component 33, as an important part of the winding component 32, includes a mounting seat 331 and a second limiting plate 332. The second limiting plate 332 is detachably arranged at one end of the winding component 32 through the mounting seat 331. At the same time, the second limiting plate 332 is located on the left side of the mounting seat 331. Such a design not only facilitates the installation and disassembly of the limiting component 33, but also makes the inner side of the second limiting plate 332 closely adhere to the wound nylon hose, which is convenient for winding the nylon hose more neatly. On the mounting seat 331, a limiting hole 3311 is provided, and this limiting hole 3311 cooperates with the positioning post 3211 on the fixing part 321. When it is necessary to install the limiting component 33 onto the winding component 32, only need to sleeved the limiting hole 3311 on the mounting seat 331 onto the positioning post 3211, then the stable installation of the limiting component 33 can be realized. This cooperation method through the positioning post 3211 and the limiting hole 3311 not only ensures the stability of the limiting component 33 during the winding process, but also makes the installation and disassembly process more simple and fast.

[0037] Referring to Figures 3 to 5 , in some embodiments of the present invention, the other end of the driving shaft 41 rotatably passes through the outside of the mounting seat 331, and a driving part 4121 is provided at the end of the other end of the driving shaft 41, and the driving part 4121 is configured to rotationally drive the driving shaft 41.

[0038] In a further design of the pipe coiling machine of the present invention, specifically, the driving shaft 41 rotatably passes through the mounting seat 331. This connection method ensures the stable rotation of the driving shaft 41 when needed, and at the same time facilitates the assembly and disassembly of the mounting seat 331. The mounting seat 331 can be easily separated or connected, improving the maintainability and flexibility of the equipment. At the other end of the driving shaft 41 passing through the outside of the mounting seat 331, a driving part 4121 is provided. This driving part 4121 is a handle or interface for the operator to rotate the driving shaft 41. By rotating the driving part 4121, the operator can easily control the rotation of the driving shaft 41, and then change the shape of the winding roller. Such a design makes the operation process more simple and fast, improving the usability and practicality of the pipe coiling machine.

[0039] Furthermore, referring to Figures 3 to 5, in some embodiments of the present invention, the drive shaft 41 includes a first shaft portion 411 and a second shaft portion 412. The first shaft portion 411 and the second shaft portion 412 are detachably connected. The first shaft portion 411 is rotatably arranged on the rotating shaft 34, and the second shaft portion 412 is rotatably arranged on the mounting seat 331. A clamping rod 4122 is arranged on the outer side of one end of the second shaft portion 412. The clamping rod 4122 is located between the first shaft portion 411 and the second shaft portion 412. A plug hole 4111 and a plurality of clamping grooves 4112 are arranged at one end of the first shaft portion 411. The plug hole 4111 is configured to accommodate one end of the second shaft portion 412. The plurality of clamping grooves 4112 are evenly distributed along the circumferential direction of the plug hole 4111. The clamping grooves 4112 are configured to clamp the clamping rod 4122.

[0040] In the design of the adjusting assembly 40 of the coiling machine of the present invention, specifically, the drive shaft 41 may specifically include a first shaft portion 411 and a second shaft portion 412. One end of the first shaft portion 411 is rotatably arranged on the rotating shaft 34, and the first shaft portion 411 and the rotating shaft 34 can rotate independently of each other. The second shaft portion 412 is rotatably arranged through the mounting seat 331 of the limiting assembly 33. The first shaft portion 411 and the second shaft portion 412 are detachably connected. Therefore, when the second shaft portion 412 is driven to rotate, the first shaft portion 411 can be driven to rotate. When the limiting assembly 33 needs to be disassembled, the first shaft portion 411 and the second shaft portion 412 can be separated.

[0041] Furthermore, a clamping rod 4122 is arranged on the outer side of one end of the second shaft portion 412 connected to the first shaft portion 411. This clamping rod 4122 plays a key role in connection and fixation. Correspondingly, a plug hole 4111 is arranged at one end of the first shaft portion 411 connected to the second shaft portion 412. The plug hole 4111 is designed to be able to accommodate one end of the second shaft portion 412, so that the two can be closely connected when connected. To ensure the stability and reliability of the connection, a plurality of clamping grooves 4112 are evenly distributed along the circumferential direction on the outer peripheral side of the plug hole 4111. These clamping grooves 4112 cooperate with the clamping rod 4122 on the second shaft portion 412. When the second shaft portion 412 is inserted into the plug hole 4111, the clamping rod 4122 will randomly snap into one of the clamping grooves 4112, thereby realizing the stable connection between the second shaft portion 412 and the first shaft portion 411. This combination of clamping and plugging not only ensures the firmness of the connection but also makes the disassembly process simple and fast. Through such a design, the adjusting assembly 40 of the coiling machine of the present invention can easily realize the connection and disassembly of the second shaft portion 412 and the first shaft portion 411 when needed, improving the maintainability and flexibility of the equipment. At the same time, this connection method also ensures the stability and reliability of the adjusting assembly 40 during the working process.

[0042] Refer to Figures 3 to 5, in some embodiments of the present invention, a first clamping portion 422 is provided at the outer end of the first support 421, a second clamping portion 442 is provided at the outer end of the second support 441, and a limiting groove 333 is provided inside the limiting component 33. The limiting groove 333 is annular and is configured to clamp the first clamping portion 422 and the second clamping portion 442.

[0043] In the design of the winding component 32 of the coiling machine of the present invention, in order to further enhance the stability of the first support 421 and the second support 441, and at the same time ensure a firm connection between them and the limiting component 33, a first clamping portion 422 is provided at the outer end of the first support 421, and a second clamping portion 442 is provided at the outer end of the second support 441. The design of these two clamping portions not only considers the structural stability but also takes into account the installation convenience. They are respectively located at the outer ends of the first support 421 and the second support 441, with accurate positions, easy to identify and operate. Correspondingly, a limiting groove 333 is provided inside the limiting component 33. This limiting groove 333 is carefully designed to be able to clamp the first clamping portion 422 and the second clamping portion 442 simultaneously, thereby realizing a tight connection between the first support 421, the second support 441 and the limiting component 33.

[0044] When the limiting component 33 needs to be installed on the winding component 32, align the limiting hole 3311 with the positioning post 3211 and insert the positioning post 3211 into the limiting hole 3311. At this time, the first clamping part 422 and the second clamping part 442 can extend into the notch edge of the limiting clamping groove 333. When the driving part 4121 is driven, the second shaft part 412 rotates, thereby driving the first shaft part 411 to rotate. When the first shaft part 411 rotates, the first movable part 322 and the second movable part 323 can be driven by the driving cam 46 to open slightly outward, so that the first clamping part 422 and the second clamping part 442 move slightly outward (in the direction away from the axis of the rotating shaft 34). At this time, the first clamping part 422 and the second clamping part 442 can move into the limiting clamping groove 333. Through the self-locking of the driving cam 46, the positions of the first movable part 322 and the second movable part 323 are kept unchanged, so that the positions of the first clamping part 422 and the second clamping part 442 are stably locked in the limiting clamping groove 333, thus realizing the stable installation of the limiting component 33. When the limiting component 33 needs to be disassembled, the second shaft part 412 is driven to reverse. At this time, the first shaft part 411 reverses synchronously. The first movable part 322 and the second movable part 323 are reset under the action of the second elastic resetting part 45. The first movable part 322 and the second movable part 323 close towards the axis of the winding roller, driving the first clamping part 422 and the second clamping part 442 to move towards the axis of the rotating shaft 34, so that the first clamping part 422 and the second clamping part 442 are separated from the limiting clamping groove 333. At this time, the limiting component 33 can be removed from the winding component 32, thus facilitating the blanking of the nylon hose.

[0045] In summary, by providing clamping parts and the limiting clamping groove 333 on the first support 421, the second support 441 and the limiting component 33, the winding machine of the present invention realizes the stable connection between the winding component 32 and the limiting component 33, and further improves the overall stability and practicability of the equipment.

[0046] Referring to Figure 1 , in some embodiments of the present invention, the guiding device 20 is located on one side of the winding component 32. The guiding device 20 includes a bracket 21 and a plurality of guiding rollers 22. The bracket 21 is slidably arranged on the frame 10. The sliding direction of the bracket 21 is parallel to the axis direction of the rotating shaft 34. The plurality of guiding rollers 22 are rotatably arranged on the bracket 21, and the nylon hose can be wound around the guiding rollers 22.

[0047] In the overall structure of the pipe coiling machine of the present invention, the guiding device 20 is arranged on one side of the winding assembly 32, playing an important role in tensioning and guiding the nylon hose. The guiding device 20 mainly consists of a bracket 21 and a plurality of guiding rollers 22. The bracket 21, as the supporting structure of the guiding device 20, is slidably arranged on the frame 10. This sliding design enables the bracket 21 to be flexibly adjusted along the direction parallel to the axis direction of the rotating shaft 34 according to actual needs. In this way, it is convenient for the nylon hose to be evenly distributed on the outer side of the winding assembly 32. On the bracket 21, a plurality of guiding rollers 22 are rotatably arranged, and they are evenly distributed to form a stable tensioning surface. During the winding process of the nylon hose, it will be wound around these guiding rollers 22, and through the rotation of the rollers, the smooth tensioning and guiding of the nylon hose are achieved. This design not only ensures the tightness and uniformity of the nylon hose during the winding process, but also effectively prevents the hose from being twisted and knotted.

[0048] Referring to Figure 1 , in some embodiments of the present invention, a plurality of guiding devices 20 and winding devices 30 are provided. The positions between the plurality of guiding devices 20 and the plurality of winding devices 30 are arranged in one-to-one correspondence. In the design of the pipe coiling machine of the present invention, in order to further improve production efficiency and meet the needs of large-scale production, a plurality of guiding devices 20 and a plurality of winding devices 30 are specially provided. These devices on the pipe coiling machine ensure that each guiding device 20 cooperates with a corresponding winding device 30. The plurality of guiding devices 20 are arranged in sequence along the length direction of the pipe coiling machine, and each guiding device 20 can work independently and is responsible for tensioning and guiding the nylon hose independently. Therefore, it can be imagined that during the winding process, after one set of guiding device 20 and winding device 30 complete winding a roll of nylon hose, the nylon hose can be quickly cut off and lapped onto another set of guiding device 20 and winding device 30, so as to achieve seamless connection of the winding work; and when another set of guiding device 20 and winding device 30 complete winding, it can be similarly and quickly switched to another set of guiding device 20 and winding device 30, and so on in a cycle, so as to achieve continuous winding without stopping the machine, thus further meeting the needs of large-scale production, improving production efficiency and the utilization rate of the equipment.

[0049] Of course, it can also be conceived that there are multiple sets of guiding devices 20 and winding devices 30, and each of them can also complete the winding work. That is, when multiple nylon hoses need to be wound simultaneously, each guiding device 20 can ensure that the hose it is responsible for remains tight, straight, and guided during the winding process. Similarly, multiple winding devices 30 are also arranged along the length direction of the hose winding machine and correspond one by one to the guiding devices 20. Each winding device 30 is equipped with an independent drive system and a winding assembly 32, and can independently adjust the winding speed as needed. This design enables the hose winding machine to process multiple nylon hoses simultaneously, greatly improving production efficiency and flexibility. In summary, by setting multiple guiding devices 20 and multiple winding devices 30 and making their positions correspond one by one, the hose winding machine of the present invention realizes the simultaneous winding and processing of multiple nylon hoses, further meets the requirements of large-scale production, and improves production efficiency and equipment utilization rate.
