[0036] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0038] As shown in Figures 1 to 5, according to one aspect of this utility model, a spiral welding machine is provided, including a coiling device 1, a welding device 2, an uncoiling device 3, and an adjusting assembly. The coiling device 1 includes a base 11 and a mandrel 12 rotatably disposed on the base 11. The mandrel 12 is used to coil material into a spiral shape. The welding device includes a main frame 21 and a welding head 22 fixed on the main frame 21. The main frame 21 can move along a first direction (X direction in the figure) so that the welding head 22 can weld the spiral material on the mandrel 12. The first direction is consistent with the axial direction of the mandrel 12. The uncoiling device 3 includes a main frame 31 and an adjusting frame 32. The adjusting frame 32 is movably disposed on the main frame 31 and is used to uncoil the spiral material. The main frame 31 can move along a first direction, allowing the adjusting frame 32 to unload the rolled material onto the core mold 12. The adjusting assembly includes a control module, a first drive member 4, and a second drive member 5. The first drive member 4 and the second drive member 5 are disposed on the main frame 31 or the adjusting frame 32 and are electrically connected to the control module respectively. The control module is configured to control the first drive member 4 to drive the adjusting frame to move along a second direction (Y direction in the figure), so that the adjusting frame has a set height relative to the main frame 31; and to control the second drive member 5 to drive the adjusting frame to rotate around the second direction, so that the adjusting frame 32 has a set angle relative to the axis of the core mold 12, where the second direction is the height direction.

[0039] Specifically, in this embodiment, the spiral welding machine uses the unwinding device 3 to unwind the steel plate coil onto the mandrel 12 of the welding device 2. The diameter of the mandrel 12 determines the diameter of the welded steel cylinder. The size of the mandrel 12 is replaced according to the required product specifications (steel cylinder diameter). In practical applications, the unwinding device needs to unwind the material to a set position on the mandrel 12 so that the chip can wind the material during rotation. This is usually achieved by adjusting the height of the adjusting frame to match the height of the material in the unwinding device 3 with that of the mandrel 12. In addition, by adjusting the angle between the axis of the adjusting frame and the mandrel 12, the adjusting frame can unwind the material onto the mandrel 12 at a certain angle. Different diameter mandrels 12 require different unwinding angles so that the material can be spirally wound onto the mandrel 12 and the seam width of the material edge during winding is kept within an appropriate range, thereby improving the welding quality of the weld head 22 when welding the seam.

[0040] In this embodiment, by setting an adjustment component, the first driving member 4 can be controlled by the control module to drive the adjustment frame to reciprocate in the second direction, so that the adjustment frame can be located at a set height in the height direction to match the height of the mandrel 12 of different specifications, so that the unwound material can be wound onto the mandrel 12 along the tangent of the mandrel 12. In addition, the second driving member 5 can be controlled by the control module to drive the adjustment frame to rotate around the second direction, that is, the adjustment frame can swing left and right relative to the mandrel 12 in the axial direction of the mandrel 12, so as to adjust the unwinding angle of the unwinding device 3, so that the unwound material can form a seam of a set width during winding. The displacement magnitude and direction of the first driving member 4 and the second driving member 5 are controlled by the control module, avoiding the process of manually prying the adjustment frame for adjustment, improving adjustment efficiency, and thus improving production efficiency. In addition, the displacement magnitude and direction of the first driving member 4 and the second driving member 5 can also be preset with input parameters according to actual needs to improve the adjustment accuracy, thereby improving the quality of the produced products.

[0041] In the above embodiment, the main frame 21 can also drive the entire unwinding device 3 to move along the first direction, so that the unwound material can be sequentially wound onto the mandrel 12 along the first direction to form a weld of a fixed width. The main frame 21 of the welding device 2 can also move along the first direction, so that after the mandrel 12 has wound the material into a spiral shape, the movement of the main frame 21 drives the welding head 22 to weld the seam, forming a steel cylinder of a set diameter. The movement of both can be achieved by power components such as motors, and is not limited here.

[0042] Optionally, as shown in Figures 1 to 3, the spiral welding machine equipment further includes a first transmission component 6 and a second transmission component 7; the first driving component 4 is disposed on the main frame 31 or the adjusting frame 32, and can cause the adjusting frame 32 to reciprocate in the second direction through the first transmission component 6; the second driving component 5 is disposed on the main frame 31 or the adjusting frame 32, and can cause the adjusting frame 32 to swing back and forth around the second direction through the second transmission component 7.

[0043] Specifically, in this embodiment, the first driving member 4 and the second driving member 5 can drive the adjustable frame through the first transmission member 6 and the second transmission member 7, respectively. The first transmission member 6 and the second transmission member 7 can be transmission components such as gears, belts, and lead screws, and the specific design is adapted to the specific structure of the main frame 31 and the adjustable frame 32, without limitation. The arrangement of the transmission members allows the first driving member 4 and the second driving member 5 to be positioned at a set location, improving transmission efficiency and reducing space occupation.

[0044] Optionally, as shown in Figures 4 and 5, both the first driving component 4 and the second driving component 5 are geared motors, and both the first transmission component 6 and the second transmission component 7 are lead screws. One end of the lead screw is connected to the output end of the geared motor, and the other end is connected to the main frame 31 or the adjusting frame 32.

[0045] Specifically, in this embodiment, both the first driving component 4 and the second driving component 5 are geared motors, which are integrated units of a reducer and a motor. These motors have a compact structure, occupy less space, and are energy-efficient, reliable, durable, and produce low vibration and noise, thus contributing to a better production environment. Furthermore, the geared motor's transmission ratio, torque ratio, speed ratio, and other parameters can be adjusted according to actual needs, improving the equipment's flexibility. The geared motor also protects the motor during transmission, extending the equipment's lifespan and reducing maintenance costs.

[0046] Furthermore, both the first transmission component 6 and the second transmission component 7 use lead screws for transmission. Lead screw transmission has high positioning accuracy and transmission accuracy, and can effectively convert rotary motion into linear motion with high conversion efficiency. In addition, lead screw transmission can withstand large loads and is suitable for large machine tools in this application. Its structure is simple and stable, which can simplify the transmission system and make the structure more compact. Combined with the geared motor, it improves the compactness and service life of the entire adjustment component and facilitates maintenance.

[0047] In one embodiment, the first transmission component 6 includes a first lead screw 61, a second lead screw 62, and a synchronous shaft 63 connecting the first lead screw 61 and the second lead screw 62. The second lead screw 62 is connected to the output end of the first drive component 4, and the second lead screw 62 is connected to the first lead screw 61 via the synchronous shaft 63. The first transmission component 6 is mounted on the adjustment frame, and driven by the first drive component 4, the entire adjustment frame can reciprocate in the height direction to improve the positioning and adjustment accuracy of height adjustment. Additionally, the second drive component 5 is connected to the adjustment lead screw via a third lead screw 71, allowing the second drive component 5 to adjust the material unwinding angle of the adjustment frame through the transmission of the third lead screw 71.

[0048] Optionally, as shown in Figures 1 and 3, the adjustment assembly further includes a first displacement sensor 8, which is connected to the control module and used to detect the height value of the adjustment frame in the second direction. The control module can control the first drive member 4 to drive the adjustment frame to move a certain amount of displacement in the second direction based on the height value. Additionally, the adjustment assembly also includes a second displacement sensor 9, which is connected to the control module and used to detect the angle between the adjustment frame and the first direction. The control module can control the second drive member 5 to drive the adjustment frame to rotate a certain amount around the second direction based on the angle value.

[0049] Specifically, in this embodiment, the arrangement of the first displacement sensor 8 and the second displacement sensor 9 enables the control module to obtain the specific height parameters of the adjustment frame and the angle with the axis of the core mold 12 through the detection results of the first displacement sensor 8 and the second displacement sensor 9. This allows the control module to perform matched adjustments to the specific height of the adjustment frame and the angle with the axis of the core mold 12 based on the detected height and angle parameters and the current diameter of the core mold 12. The adjustment frame can be set with an initial height and an initial angle, which can be designed to be 90° with the axis of the core mold 12 for easy adjustment.

[0050] In the above embodiments, the first displacement sensor 8 can be an optical sensor, a mechanical sensor, etc., and can be designed according to actual needs, without limitation. The setting of the first displacement sensor 8 and the second displacement sensor 9 further improves the automation level and adjustment accuracy of the spiral welding machine, resulting in higher adjustment efficiency and product quality.

[0051] Optionally, as shown in Figures 2 and 4, the first displacement sensor 8 is a pull-cord displacement sensor, which includes a first pull-cord 81 and a first detection unit 82. The first detection unit 82 is disposed on the main frame 31, so that the first pull-cord 81 is connected to the adjustable frame. Additionally, the second displacement sensor 9 is a pull-cord displacement sensor, which includes a second pull-cord 91 and a second detection unit 92. The second detection unit 92 is disposed on the main frame 31, so that the second pull-cord 91 is connected to the adjustable frame.

[0052] Specifically, in this embodiment, both the first displacement sensor 8 and the second displacement sensor 9 are pull-string sensors, which have high measurement accuracy and strong flexibility, can adapt to different installation environments and space constraints, are reliable and durable, and can easily realize real-time detection parameters and transmit the detection results in real time, further improving the working efficiency of the control module in controlling the first drive component 4 and the second drive component 5.

[0053] In this embodiment, the first displacement sensor 8 includes a first pull rope 81 and a first detection unit 82, and the second displacement sensor 9 includes a second pull rope 91 and a second detection unit 92. The first displacement sensor 8 and the second displacement sensor 9 measure the height value of the adjustment frame and the angle value with the first direction. After the detection results are obtained by the control module, the control module adjusts the height and angle of the adjustment frame by controlling the first drive component 4 and the second drive component 5.

[0054] In some embodiments, the control module can also automatically calculate the swing angle of the adjustable frame (i.e., the angle with the first direction) based on manually input parameter information, convert the swing angle into radians, compare it with the measured value, and then determine the moving direction and distance of the second drive member 5. The second transmission member 7 acts on the rear of the adjustable frame, controlling its swing angle through the second drive member 5. The height adjustment follows the same logic and will not be elaborated here. The adjustable frame is raised or lowered by adjusting the first lead screw 61, the second lead screw 62, and the synchronous shaft 63.

[0055] In practical applications, the above data (such as height values, arc length, etc.) can be stored in the control module in the form of a formula, or it can be fine-tuned and saved according to on-site requirements, so that it can be directly applied in subsequent production, further improving the adjustment efficiency.

[0056] Optionally, the adjustment component also includes a display module, which is connected to the control module and can be used to input adjustment parameters to the control module and display the adjustment parameters.

[0057] Specifically, in this embodiment, the display module is designed to facilitate operation by the user. The display module can be designed as a touchscreen, allowing the user to input or modify adjustment parameters via the touchscreen, thus improving operational convenience.

[0058] Optionally, as shown in Figures 1 and 3, an unwinding shaft 321 parallel to the axis of the core mold 12 is provided on the adjusting frame. The unwinding shaft 321 is used to place the rolled material. The control module can unwind the rolled material on the unwinding shaft 321 to a position tangent to the core mold 12 through the first driving member 4 and the second driving member 5.

[0059] Specifically, in this embodiment, the unwinding shaft 321 is used to assemble the rolled material, allowing it to be smoothly unwound onto the mandrel 12. The control module controls the first drive component 4 and the second drive component 5 to unwind the rolled material on the unwinding shaft 321 to a position tangent to the mandrel 12, making the spiral-shaped material wound around the mandrel 12 more in line with production requirements and improving product quality.

[0060] Optionally, as shown in Figures 1 and 3, the spiral welding machine equipment also includes a proximity switch, which is mounted on the main frame 31 or the adjusting frame 32 and connected to the control module to limit the size of the set angle.

[0061] Specifically, in this embodiment, a proximity switch can be installed on the main frame 31 or the adjusting frame to prevent collisions with the second displacement sensor 9 when the angle between the adjusting frame and the core mold 12 axis is too small, thereby improving the safety and reliability of the entire device.

[0062] The above embodiments mainly describe the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. For the sake of brevity, they will not be elaborated here.

[0063] While specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
