[0002] Commonly used spring heating wire winding machines are generally only used to wind shorter heating wires, which are mainly used for heating components of some electrical appliances. However, with the gradual increase in the requirements for heating efficiency, it is difficult to meet the requirements for heating components in some large spaces, such as heating components for indoor floor heating. At present, the main consideration is to achieve the heating requirements of large spaces by pre-setting large spring heating wires, which can achieve better heating efficiency. However, the current spring heating wire winding machines can only be used to wind small heating wires, which is difficult to meet the winding requirements of larger and longer spring heating wires.

[0003] Since the core rod of the traditional spring heating wire winding machine is relatively short and thin, after the heating wire is wound, the core rod can be manually pulled away by a large distance, and then the heating wire wound on the core rod can be pulled out. However, when winding a larger and longer spring heating wire, an extended core rod and a core rod with a larger radius are required for winding, and the wound heating wire cannot be taken out by the above method.

[0051] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0053] In the description of the present invention, if there is a description of first and second, it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the sequence of the indicated technical features.

[0054] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0055] like Figure 1 As shown, the extended spring heating wire winding machine according to the embodiment of the present invention includes a frame, a wire feeding mechanism 200, a head mandrel fixing mechanism 300, a tail mandrel fixing mechanism 400, and a mandrel rotation driving mechanism. The frame includes a head frame 110, a tail frame 120 and at least one connecting frame 130 arranged between the head frame 110 and the tail frame 120. The total length of the frame can be configured according to the specific length of the mandrel. The wire feeding mechanism 200 can be movably arranged on the frame, and the wire feeding mechanism 200 is configured with a translation driving mechanism that can drive the wire feeding mechanism 200 to move on the frame to wind the wire on the mandrel 900; the head mandrel fixing mechanism 300 is arranged on the head frame 110, and the head mandrel fixing mechanism 300 includes a A front mandrel fixing assembly 310; a tail mandrel fixing mechanism 400 can be movably arranged on the tail frame 120, the tail mandrel fixing mechanism 400 includes a rear mandrel fixing assembly 410 capable of fixing the other end of the mandrel 900, and the tail mandrel fixing mechanism 400 is provided with a tail deviation driving mechanism capable of driving it to move on the tail frame 120; a mandrel rotation driving mechanism is arranged on the frame, the mandrel rotation driving mechanism includes a driving assembly 510 and a linkage shaft mechanism capable of being driven to rotate by the driving assembly 510, the linkage shaft mechanism includes a main shaft assembly connected to the front mandrel fixing assembly 310, a swing shaft 540 connected to the rear mandrel fixing assembly 410, and a connecting assembly connecting the main shaft assembly and the swing shaft 540, and the connecting assembly includes a telescopic mechanism 550 and a universal coupling 560.

[0056] During operation, the two ends of the mandrel 900 are respectively fixed to the head mandrel fixing mechanism 300 and the tail mandrel fixing mechanism 400, the mandrel rotation drive mechanism drives the mandrel 900 to rotate, and the wire feeding mechanism 200 feeds out metal to be wound on the mandrel 900. At the same time, the wire feeding mechanism 200 moves along the length direction of the mandrel 900, so that the metal wire can be wound into a spring shape. After the winding is completed, the rear mandrel fixing assembly 410 releases the mandrel 900, and the tail deviation drive mechanism drives the tail mandrel fixing mechanism 400 to move away from the mandrel 900, so that the spring heating wire can be taken out from the end of the mandrel 900, and the spring heating wire can be taken out without pushing the mandrel 900 or only by pushing the mandrel 900 at a small angle, so that the wound heating wire can be conveniently taken out.

[0057] The main shaft assembly is connected to the swing shaft 540 through the telescopic mechanism 550 and the universal coupling 560, so that when the tail mandrel fixing mechanism 400 moves away from the mandrel 900, it can still maintain connection with the mandrel rotation drive mechanism. After the finished product is taken, it can be driven directly, which is easy to use and has high work efficiency.

[0058] Specifically, in the present invention, at least one connecting frame 130 is configured to extend the length of the frame to adapt to the mandrel 900. The number of connecting frames 130 can be configured according to the length of the mandrel 900 to improve versatility.

[0059] Specifically, the front mandrel fixing assembly 310 and the rear mandrel fixing assembly 410 are connected to the linkage shaft mechanism through a transmission mechanism such as a synchronous belt.

[0060] In some embodiments of the present invention, the core rod 900 is relatively long and heavy, and it is very inconvenient to swing it at a large angle. Through the above structure, the tail core rod fixing mechanism 400 is moved away from the core rod 900, so that the operator can directly take out the spring heating wire (without moving the core rod 900), or only needs to push the core rod 900 to move a small range to take out the spring heating wire, which can facilitate the workers' operation and improve work efficiency.

[0061] In some embodiments of the present invention, the main shaft assembly is connected to the swing shaft 540 via a telescopic mechanism 550 and a universal coupling 560, so that the tail mandrel fixing mechanism 400 can remain connected during movement, and after the tail mandrel fixing mechanism 400 is reset, it can maintain normal transmission even when it is not precisely aligned, making the mechanism more reliable.

[0062] Specifically, in actual use, the tail core rod fixing mechanism 400 needs to be frequently deviated to facilitate the removal of finished products. If precise alignment is performed each time, a lot of time will be wasted, and it is also difficult to ensure that each alignment can be accurate. By configuring the telescopic mechanism 550 and the universal coupling 560, a small range of deviation does not affect the normal drive of the tail core rod fixing mechanism 400, so there is no need for frequent debugging, it is easy to use, and has high work efficiency.

[0063] In some embodiments of the present invention, the swing shaft 540 and the connecting assembly are arranged on the tail frame 120, the driving assembly 510 is arranged on the head frame 110, and the main shaft assembly includes an output shaft 531 arranged on the head frame 110 and a connecting shaft 532 configured in a one-to-one correspondence with the connecting frame 130, the connecting shaft 532 is rotatably arranged on the connecting frame 130, and the output shaft 531 is respectively connected to the front mandrel fixing assembly 310 and the driving assembly 510, and the output shaft 531 and the connecting shaft 532, as well as adjacent connecting shafts 532 are connected via a coupling 533 to realize the transmission connection between the front mandrel fixing assembly 310 and the rear mandrel fixing assembly 410.

[0064] Specifically, Figure 1 , Figure 5 As shown, the driving assembly 510 is a motor mechanism, which is connected to the output shaft 531 through a synchronous belt mechanism. A connecting shaft 532 is set on each connecting frame 130 through a rotating shaft seat, so that when the frame is extended or shortened, the transmission connection between the front core rod fixing assembly 310 and the rear core rod fixing assembly 410 can be maintained.

[0065] Specifically, the coupling 533 is a cross universal coupling, which can ensure that the connecting frame 130 can maintain normal transmission even when a small range of displacement occurs, thereby facilitating the debugging and assembly of the equipment.

[0066] It is conceivable that the main shaft assembly can also be an integral long shaft, which can also meet the transmission requirements.

[0067] In some embodiments of the present invention, the telescopic mechanism 550 includes a fixed shaft 551, a connecting sleeve 552 and an insert shaft 553. One end of the fixed shaft 551 is connected to the connecting shaft 532 through a coupling 533, and the other end of the fixed shaft 551 is connected to the connecting sleeve 552. The end of the insert shaft 553 is provided with a plug-in section with a non-circular cross-section and extending along the length direction of the plug-in shaft 553. The connecting sleeve 552 is provided with a plug-in hole 554 for the plug-in section to be inserted and slide, so that the insert shaft 553 can maintain normal transmission when it is telescoped.

[0068] Specifically, Figure 3 , Figure 4 As shown, when the insertion shaft 553 is extended and retracted, the insertion section remains connected to the insertion hole 554 to achieve a transmission connection, thereby maintaining a normal transmission effect during axial extension and retraction.

[0069] It is conceivable that the connecting sleeve 552 may not be configured, so that the insertion shaft 553 and the fixed shaft 551 are directly plugged and matched, and the effect of telescopic transmission can also be achieved.

[0070] like Figure 4 As shown, in some embodiments of the present invention, the hole wall of the plug hole 554 is provided with a rolling element 555 capable of contacting the plug section to improve the smoothness of the telescopic sliding and improve the flexibility of the tail core rod fixing mechanism 400 when moving.

[0071] In some embodiments of the present invention, the plug-in hole 554 passes through the connecting sleeve 552, and the fixed shaft 551 is provided with an inner hole 557. The insertion shaft 553 can pass through the plug-in hole 554 and be inserted into the inner hole 557. A longer insertion shaft 553 can be configured to increase the range of telescopic sliding.

[0072] Specifically, Figure 4 As shown, one end of the fixed shaft 551 that cooperates with the connecting sleeve 552 is a hollow structure, and an inner hole 557 is configured for the insertion shaft 553 to be inserted. When in use, a longer insertion shaft 553 can be selected to meet different usage requirements.

[0073] In some embodiments of the present invention, the plug-in section is provided with at least one mating plane 556 extending along the length direction of the insertion axis 553, and the rolling element 555 is a cylindrical roller that can cooperate with the mating plane 556. The cylindrical roller contacts the mating plane 556 and forms a transmission structure, and the transmission effect is better.

[0074] Specifically, Figure 4 As shown, the main body of the insertion shaft 553 is a round shaft, and the matching planes 556 are configured as four and evenly distributed in the circumference of the insertion shaft 553. The cylindrical rollers are configured accordingly and are configured in multiple numbers, so that a better transmission effect can be achieved.

[0075] In some embodiments of the present invention, the telescopic mechanism 550 includes an elastic member, which can generate an elastic force to push the insertion shaft 553 toward the connecting sleeve 552, so that the telescopic reset of the insertion shaft 553 is smoother.

[0076] Specifically, the elastic member is a tension spring, one end of which is connected to the connecting sleeve 552 , and the other end of which is connected to the universal coupling 560 or the insert shaft 553 (not shown in the figure) to provide a restoring elastic force for the insert shaft 553 .

[0077] In some embodiments of the present invention, the connecting frame 130 is provided with a mandrel supporting mechanism 600 for supporting the mandrel 900, so as to improve the supporting effect of the mandrel and reduce the occurrence of mandrel deformation.

[0078] Specifically, Figure 5As shown, since the core rod 900 is relatively long, the middle portion thereof is very easy to sink and deform. By configuring the core rod support mechanism 600, the deformation of the core rod 900 is reduced, thereby improving the quality of the heating wire winding.

[0079] In some embodiments of the present invention, the mandrel support mechanism 600 includes a support frame 610 arranged on the connecting frame 130, a lifting mechanism 620 arranged on the support frame 610, and a linkage lever 650 arranged on the support frame 610. The lifting mechanism 620 is provided with a lifting platform 630, and the lifting platform 630 is provided with a lower supporting member 640. The middle part of the linkage lever 650 can be rotatably arranged on the support frame 610. One end of the linkage lever 650 corresponds to the lifting platform 630, and the other end of the linkage lever 650 is provided with an upper positioning member 660 corresponding to the lower supporting member 640. The lifting mechanism 620 can drive the lifting platform 630 to move up and down. When the lifting platform 630 is raised, it can contact the linkage lever 650 to make the upper positioning member 660 and the lower supporting member 640 move relative to each other. A positioning space corresponding to the mandrel 900 can be formed between the upper positioning member 660 and the lower supporting member 640, thereby supporting the mandrel 900.

[0080] Specifically, Figure 6 As shown, the lifting mechanism 620 is a cylinder, which realizes the positioning and loosening of the mandrel 900 through a linkage structure. In the specific implementation process, a position detection device is configured to detect the position of the wire feeding mechanism 200. When the wire feeding mechanism 200 has not reached the position of the mandrel supporting mechanism 600, the mandrel supporting mechanism 600 normally positions the mandrel 900 to reduce its deformation. When the position detection device detects that the wire feeding mechanism 200 reaches the position of the mandrel supporting mechanism 600, the lifting platform 630 moves downward, thereby opening the upper positioning member 660 and the lower supporting member 640, so as to facilitate the normal winding of the wire feeding mechanism 200.

[0081] Of course, in the specific implementation process, pneumatic fingers can also be used to clamp and position the core rod 900.

[0082] like Figure 6 As shown, in some embodiments of the present invention, a roller 670 is provided at one end of the linkage lever 650 corresponding to the lifting platform 630 to improve the flow of linkage driving.

[0083] like Figure 1 , Figure 5 , Figure 7 As shown, in some embodiments of the present invention, the wire feeding mechanism 200 is arranged on a translation plate 210, and the translation plate 210 is arranged on a frame through a sliding mechanism. The head frame 110, the connecting frame 130 and the tail frame 120 are respectively provided with guide rails 214 that can be connected to each other, and the translation plate 210 is provided with a slider that slides with the guide rail 214, thereby realizing the sliding setting of the wire feeding mechanism 200.

[0084] Specifically, a guide rail 214 is provided on the connecting frame 130 , and when a plurality of connecting frames 130 are spliced ​​and used, the normal movement of the wire feeding mechanism 200 is not affected.

[0085] It is conceivable that, in some embodiments of the present invention, the sliding mechanism may also be an optical axis sliding fit mechanism, which will not be described in detail herein.

[0086] like Figure 1 , Figure 5 , Figure 7 , Figure 8 As shown, in some embodiments of the present invention, the wire feeding mechanism 200 is arranged on the translation plate 210 and is equipped with a translation driving mechanism that can drive the translation plate 210 to move along the length direction of the core rod 900. The translation driving mechanism is a spur rack driving mechanism. The spur rack driving mechanism includes a translation driving motor 211 arranged on the translation plate 210, and a driving gear arranged on the output shaft of the translation driving motor 211. The head frame 110, the connecting frame 130 and the tail frame 120 are respectively provided with spur racks 213 that can be connected to each other and can mesh with the driving gear. When the translation driving motor 211 drives the driving gear to roll along the spur rack 213, it can drive the wire feeding mechanism 200 to translate, thereby meeting the winding requirements.

[0087] Specifically, a spur rack 213 is provided on the connecting frame 130, and when a plurality of connecting frames 130 are spliced ​​and used, normal transmission performance can be maintained, thereby improving versatility.

[0088] It is conceivable that, in some embodiments of the present invention, the translation drive mechanism may also be a screw mechanism, etc., which will not be described in detail here.

[0089] In some embodiments of the present invention, a wire feeding mechanism 200 is disposed on a translation plate 210, and the wire feeding mechanism 200 includes a reeling mechanism 220 for feeding out metal wire, and the reeling mechanism 220 includes a turntable assembly 221 rotatably disposed on the translation plate 210, and the turntable assembly 221 is provided with at least two groups of external support assemblies 222 annularly distributed on the turntable assembly 221, and the external support assembly 222 is movably disposed on the turntable assembly 221, and the unwinding mechanism 220 includes a wire supporting mechanism that can drive the external support assembly 222 to slide along the radial direction of the turntable assembly 221, thereby being able to tension the metal wire wound on the unwinding mechanism 220 and improving the smoothness of the metal wire output.

[0090] Specifically, Figure 1 , Figure 7 , Figure 8 , Fig.11 , Fig.12As shown, a long roller is arranged on the outer support component 222, and the metal wire is wound on the outer side of the outer support component 222. The wire support mechanism can push the outer support component 222 to move outward to tighten the metal wire and avoid the situation that the metal wire becomes loose.

[0091] Of course, in the specific implementation process, the metal wire can also be wound by conventional wire coils, which can also meet the unwinding requirements.

[0092] like Fig.11 , Fig.12 As shown, in some embodiments of the present invention, the wire supporting mechanism includes a wire supporting cylinder 223 disposed on a turntable assembly 221, and a piston rod of the wire supporting cylinder 223 is connected to an outer supporting assembly 222 via a connecting rod assembly 224, thereby meeting the wire supporting requirements.

[0093] It is conceivable that, in some embodiments of the present invention, the wire support mechanism may also be a cylinder that directly pushes the external support assembly 222 outward.

[0094] like Fig.11 , Fig.12 As shown, in some embodiments of the present invention, the unwinding mechanism 220 is equipped with a magnetic powder brake 225, which can provide a certain rotational resistance so that the sent metal wire remains in a tensioned state. The magnetic powder brake 225 can be used for emergency braking to improve safety in use.

[0095] In some embodiments of the present invention, the wire feeding mechanism 200 includes a translation plate 210, a translation driving mechanism, a transverse plate 215, and a transverse driving mechanism arranged on a frame. The translation driving mechanism can drive the translation plate 210 to move along the length direction of the core rod 900, the transverse plate 215 can be movably arranged on the translation plate 210, and the transverse driving mechanism can drive the transverse plate 215 to move along the lateral direction of the core rod 900. A reeling mechanism 220 is arranged on the translation plate 210, and a wire jamming detection mechanism 230, a buffer mechanism 240, a straightening mechanism 250, and a cutting mechanism 260 are arranged on the transverse plate 215. The metal wire is fed out through the reeling mechanism 220, and is fed to the core rod 900 through the wire jamming detection mechanism 230, the buffer mechanism 240, the straightening mechanism 250, and the cutting mechanism 260 in sequence.

[0096] Specifically, Figure 7 , Figure 8 , Fig. 9 As shown, the transverse driving mechanism is a cylinder driving mechanism, which can drive the wire detection mechanism 230, the buffer mechanism 240, the straightening mechanism 250, and the cutting mechanism 260 to move as a whole, and can cooperate with the cutting mechanism 260 to cut the lead wire of a set length for the spring heating wire. When the winding is completed, the transverse driving mechanism drives the cutting mechanism 260 to move away from the core rod. When it moves to the set length, the metal wire is cut off to obtain the set length of the lead wire (unwound metal wire) to meet different usage requirements.

[0097] Specifically, the wire jam detection mechanism 230 detects the tension or movement resistance of the metal wire by winding the metal wire on a roller or a roller, and detects whether the metal wire is in a normal conveying state, so as to cooperate with the control system of the spring heating wire winding machine to control the unwinding mechanism to stop or the equipment to stop.

[0098] Specifically, the buffer mechanism 240 is used to store the metal wire, and includes a winding wheel 241 set by a spring 242. The metal wire winds around the winding wheel 241. When there is a problem with the metal wire transportation, such as wire jamming, the metal wire compresses the spring 242 through the winding wheel 241, so that the winding wheel 241 moves to output the metal wire stored in the buffer mechanism 240, thereby avoiding the occurrence of sudden jamming, overloading, etc. of the equipment.

[0099] Specifically, the straightening mechanism 250 includes a plurality of groups of straightening rollers 251 distributed vertically, and the metal wire passes straightly between the straightening rollers 251, thereby achieving a straightening effect. In addition, the upper and lower rollers are provided with an opening mechanism for easy maintenance and threading.

[0100] Specifically, the cutting mechanism 260 includes an electric cylinder 261 and a cutter 262 driven by the electric cylinder 261 to cut the metal wire.

[0101] In some embodiments of the present invention, a guide wheel group 280 is provided on the transverse plate 215, and the metal wire is sent out through the unwinding mechanism 220, and is sequentially sent through the wire detection mechanism 230, the buffer mechanism 240, the straightening mechanism 250, the cutting mechanism 260, and the guide wheel group 280 to the core rod 900. The guide wheel group 280 guides the metal wire to be sent out, thereby improving the output accuracy.

[0102] In some embodiments of the present invention, an adjustment plate 216 and a height adjustment mechanism 217 capable of adjusting the height distance between the adjustment plate 216 and the transverse plate 215 are provided on the transverse plate 215, and a buffer mechanism 240, a straightening mechanism 250 and a cutting mechanism 260 are provided on the adjustment plate 216 to adjust the wire feeding height to meet different winding requirements.

[0103] Specifically, Fig. 9 As shown, the height adjustment mechanism 217 is a screw adjustment mechanism, which achieves the effect of height adjustment by rotating the screw or nut. In actual use, the winding heights of mandrels 900 with different radii are different. The above structure can improve the versatility of the equipment.

[0104] In some embodiments of the present invention, the wire feeding mechanism 200 includes a translation plate 210 and a translation driving mechanism arranged on a frame. The translation driving mechanism can drive the translation plate 210 to move along the length direction of the mandrel 900. The translation plate 210 is provided with a mandrel following mechanism 270. The mandrel following mechanism 270 can move with the translation plate 210 and can position the mandrel 900. The mandrel following mechanism 270 can be used to position the mandrel during winding, thereby improving the winding accuracy.

[0105] Specifically, Figure 7 , Figure 8 , Fig. 9 As shown, the mandrel follower mechanism 270 is arranged in front of the metal wire outlet (in front of the winding direction), which can position the mandrel before the metal wire is wound, thereby improving the winding accuracy.

[0106] like Fig.10 As shown, in some embodiments of the present invention, the core rod follower mechanism 270 includes a follower frame 271 arranged on the translation plate 210, and a clamping mechanism 272 arranged on the follower frame 271. A follower roller 273 is arranged on the clamping member of the clamping mechanism 272, and the clamping mechanism 272 can clamp and position the core rod 900 through the follower roller 273.

[0107] Specifically, the clamping mechanism 272 is a pneumatic finger, and the follower roller 273 is arranged on the clamping finger portion of the pneumatic finger. An annular groove is arranged on the outer periphery of the follower roller 273, corresponding to the core rod, so as to position the core rod.

[0108] like Fig.10 As shown, in some embodiments of the present invention, the translation plate 210 is provided with a follower drive mechanism 274 capable of driving the follower frame 271 away from or close to the mandrel 900 to position the mandrel or release the mandrel.

[0109] Specifically, the follower drive mechanism 274 is a cylinder mechanism, and the piston rod of the cylinder mechanism drives the follower frame 271 to move through the inclined surface pushing structure.

[0110] Of course, in the specific implementation process, the cylinder mechanism can also directly drive the follower frame 271 to move.

[0111] In some embodiments of the present invention, the tail deviation drive mechanism includes a lateral deviation drive mechanism capable of driving the tail mandrel fixing mechanism 400 to move along the lateral direction of the mandrel and an axial movement drive mechanism 430 capable of driving the tail mandrel fixing mechanism 400 to move along the length direction of the mandrel, so as to realize the deviation drive of the tail mandrel fixing mechanism 400.

[0112] Specifically, Figure 3As shown, the lateral deviation drive mechanism and the axial movement drive mechanism 430 are both cylinder drive mechanisms, and are arranged in two axes vertically and horizontally, realizing the horizontal two-axis drive of the tail mandrel fixing mechanism 400, which can meet the deviation drive requirements of the tail mandrel fixing mechanism 400.

[0113] It is conceivable that the tail deviation driving mechanism may also be a swing driving mechanism, which drives the tail mandrel fixing mechanism 400 to deviate by swinging.

[0114] like Figure 2 As shown, in some embodiments of the present invention, the head mandrel fixing mechanism 300 includes a front bracket 320 fixed to the head frame 110, and the front bracket 320 is rotatably provided with a rotating shaft 330, and the rotating shaft 330 is transmission-connected to the mandrel rotation driving mechanism, and the rotating shaft 330 is at least partially a through structure. The front mandrel fixing assembly 310 is a clamping mechanism, and the clamping mechanism is arranged on the rotating shaft 330. The metal wire used for winding the spring heating wire can be inserted into the rotating shaft 330 through the clamping mechanism to protect the lead of the wound spring heating wire.

[0115] Specifically, in some heating wires, a lead wire of a certain length is required to facilitate installation or connection. When the present invention is working, the end lead wire of the heating wire can be inserted into the rotating shaft 330 to avoid unnecessary accidents caused by the swing of the lead wire.

[0116] Of course, the invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
