As the core component of the wire supporting device, the wire supporting roller is mainly used to support the enameled wire and guide it to remain stable during the painting process. However, during the use of the existing wire supporting device, the replacement and maintenance of the wire supporting roller often bring inconveniences, especially when producing enameled wires of different specifications, the wire supporting roller needs to be replaced frequently. This process usually requires stopping the machine for disassembly, removing the rotating shaft that fixes the wire supporting roller, manually replacing the new wire supporting roller, and then reassembling. This type of operation is not only time-consuming and labor-intensive, but also easily causes wear and misoperation of the equipment, which seriously affects the production efficiency and the normal use of the equipment.

[0029] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] See also Figures 1 to 10 As shown: a quick-change wire-supporting device for enameled wire painting, used for quickly installing a wire-supporting roller 1, the wire-supporting roller 1 is composed of a rotating shaft 13 and a left roller body 11 and a right roller body 12 coaxially arranged on both sides of the rotating shaft 13, the quick-change wire-supporting device includes: a base frame 2; a pressing module 3, the pressing module 3 is provided with two groups, and the two groups of pressing modules 3 are symmetrically arranged on the base frame 2 in a horizontal state; a limit clamping module 4, the limit clamping module 4 is provided with two groups, and the two groups of limit clamping modules 4 are symmetrically fixedly arranged on the left roller body 11 and the right roller body 12; and the outer side of each group of the limiting clamping modules 4 is also fixedly provided with a clamping head 41 that can be clamped with the pressing end of the pressing module 3; the limiting module 5, the limiting module 5 is provided with two groups, the two groups of limiting modules 5 are respectively slidably arranged on the outer sides of the two groups of the limiting clamping modules 4, and the limiting surfaces of the two groups of the limiting modules 5 are in abutment and flush with the clamping surfaces of the two groups of the limiting clamping modules 4; when the limiting surfaces of the two groups of the limiting modules 5 and the clamping surfaces of the two groups of the limiting clamping modules 4 are offset to a preset angle, the limiting clamping module 4 is in a locked posture.

[0031] The wire supporting device is provided with two groups, and the two groups of wire supporting devices are respectively used to synchronously limit and fix the front and rear ends of the left roller body 11 and the right roller body 12, so as to synchronously achieve the effect of clamping the left roller body 11 and the right roller body 12 on the main shaft.

[0032] The clamping surface of the position-limiting clamping module 4 is the surface where the two groups of position-limiting clamping modules 4 contact each other after clamping and affixing, and the fixing surface of the fixing module 5 is the surface where the two groups of fixing modules 5 contact each other in the fixing state.

[0033] When the left roller body 11 and the right roller body 12 need to be clamped synchronously and installed on the main shaft to realize the rapid replacement of the wire support roller 1, first, the position-limiting clamping module 4 installed at both ends of the left roller body 11 and the right roller body 12 will be clamped with the pressing end of the pressing module 3 through the clamping head 41 structure. At this time, the position-limiting clamping module 4 cooperates with the pressing module 3 to ensure that the left roller body 11 and the right roller body 12 are in a parallel and relatively fixed state under the drive of the pressing module 3. This structure facilitates the rapid and stable installation of the left roller body 11 and the right roller body 12 to form a complete wire support roller 1.

[0034] When the wire-supporting roller 1 is to be quickly replaced, the user only needs to drive the pressing module 3 to make the two sets of pressing modules 3 synchronously drive the two sets of limiting clamping modules 4 to move in opposite directions, so that the left roller body 11 and the right roller body 12 are synchronously moved toward the center until the two are tightly fitted and firmly clamped on both sides of the rotating shaft 13, and spliced ​​into a complete wire-supporting roller 1. In this process, the driving action of the limiting module 5 ensures the stability of the spliced ​​wire-supporting roller 1, and the limiting surface of the limiting module 5 will be offset from the clamping surface of the two sets of limiting clamping modules 4, thereby achieving a locking effect on the rotating shaft 13. The locking action is completed by the offset angle of the limiting module 5, and the optimal offset angle is set to ninety degrees, thereby effectively preventing the wire-supporting roller 1 from loosening due to vibration or external force during use.

[0035] By adopting a split structure and a splicing locking mechanism, the replacement process of the wire roller 1 is simplified, eliminating the cumbersome operations required for disassembly and installation in the traditional method. Through the synergistic effect of the limit clamping module 4 and the pressing module 3, the wire roller 1 can be quickly replaced without disassembling the equipment, reducing the difficulty of operation and equipment downtime. In addition, the spliced ​​wire roller 1 ensures stability and safety after installation through a precise locking mechanism, effectively improving production efficiency and reducing equipment failure rate and maintenance costs.

[0036] See also Figure 8 As shown: the limiting clamping module 4 also includes a clamping seat 42 capable of clamping the left roller body 11 on the outside of the rotating shaft 13 and a groove 43 capable of engaging with its limiting end when the two groups of the limiting modules 5 are deflected to a preset angle; the clamping head 41 is fixedly arranged on the side of the clamping seat 42 away from the clamping surface; the groove 43 is opened on the surface of the clamping seat 42 and is arranged close to the clamping surface of the clamping seat 42.

[0037] When it is necessary to clamp the left roller body 11 outside the rotating shaft 13 through the clamping seat 42, first, the clamp head 41 preset on the outer wall of the clamping seat 42 is matched with the pressing end of the pressing module 3, and the clamping seat 42 is fixed to the pressing end of the pressing module 3 through the quick-installation structure of the clamp head 41, so as to realize the rapid installation of the limit clamping module 4. At this time, the left roller body 11 and the right roller body 12 are connected to the front end of the pressing module 3 through their respective limit clamping modules 4.

[0038] After the two sets of limiting clamping modules 4 have fixed the left roller body 11 and the right roller body 12 respectively, in order to make the left roller body 11 and the right roller body 12 approach each other and tightly clamped outside the rotating shaft 13 to form a complete wire supporting roller 1, it is only necessary to synchronously drive the two sets of pressing modules 3 so that the pressing ends thereof extend outward and drive the left roller body 11 and the right roller body 12 to synchronously move toward the center, thereby realizing the tight clamping of the left roller body 11 and the right roller body 12, and finally fixing them outside the rotating shaft 13 to complete the assembly of the wire supporting roller 1.

[0039] The design of quick clamping and synchronous drive enables quick assembly of the wire support roller 1, significantly improving the work efficiency when replacing the wire support roller 1. Compared with the traditional method, the requirements for equipment disassembly and operator skills are reduced, making the installation process of the wire support roller 1 simpler, faster and safer.

[0040] See also Figure 8 and Fig.10 As shown: the clamp seat 42 is a rectangular block arranged in a U shape and a first slide rail 47 capable of guiding the sliding of the limiting module 5 is fixedly arranged on the surface; the surface of the clamp seat 42 is also penetrated by a first card slot 44 matching the rotating shaft 13 and a pin hole 421 which is transversely penetrated and opened on the side wall of the clamp seat 42; the first card slot 44 is centrally penetrated and opened in the middle of the clamp seat 42 and close to one side of the clamping surface of the clamp seat 42; the first slide rail 47 is coaxially fixedly arranged on the surface of the clamp seat 42 and arranged on the outer side of the first card slot 44 and coaxially arranged with the first card slot 44.

[0041] The clamping seat 42 is fixedly connected to the left roller body 11 through a pin 422, and the pin 422 corresponds to the pin hole 421 of the clamping seat 42 one by one, forming multiple groups of pin 422 hole pairs. The function of the pin 422 is to ensure a firm fixed connection between the clamping seat 42 and the left roller body 11, thereby providing a stable support structure. The first card slot 44 is designed in a semicircular shape, and its inner diameter matches the outer diameter of the rotating shaft 13, ensuring the perfect match between the first card slot 44 and the rotating shaft 13, and ensuring precise positioning and stability during the connection process.

[0042] When the left roller body 11 and the clamp seat 42 need to be fixedly connected, the staff only needs to take out the pin shaft 422, and pass the pin shaft 422 through the pin holes 421 in the left roller body 11 and the clamp seat 42 in turn, and use the pin holes 421 to accurately align the positions, so as to achieve the fixed installation effect between the left roller body 11 and the clamp seat 42. In this process, the cooperation between the pin shaft 422 and the pin hole 421 not only provides a mechanical connection, but also can effectively reduce the error during installation and ensure the installation accuracy.

[0043] See also Figure 8 As shown, a rubber pad 45 is embedded in the inner wall of the first slot 44 of the clamp seat 42 .

[0044] When the clamping seat 42 clamps the rotating shaft 13 through the first clamping slot 44, a small gap may occur between the first clamping slot 44 and the rotating shaft 13 due to manufacturing and assembly errors, thereby affecting the stability of the clamping. By embedding the rubber pad 45 in the inner wall of the first clamping slot 44, the elastic deformation characteristics of the rubber pad 45 can be used to compensate for the gap during the clamping process, so that the rotating shaft 13 can be clamped more tightly, thereby improving the assembly accuracy, enhancing the fit between the clamping seat 42 and the rotating shaft 13, and avoiding looseness or slippage caused by tolerance problems. In addition, the rubber pad 45 can also provide a certain buffering effect when the rotating shaft 13 rotates, reducing the direct friction between the clamping seat 42 and the rotating shaft 13, thereby extending the service life of the device and improving stability.

[0045] See also Figure 8 As shown, a positioning magnet 46 is embedded on the surface of the clamp seat 42 , and a plurality of groups of the positioning magnets 46 are equidistantly arranged along the axis of the first clamping slot 44 .

[0046] When the limiting module 5 is driven to rotate and adjust around the axis of the first slot 44, so as to achieve locking between the two groups of limiting clamping modules 4, the positioning magnet 46 can adsorb and position the limiting module 5 that is rotated and adjusted to different angles; so that the limiting module 5 can remain stable after being adjusted to a specific angle position, avoiding the displacement of the limiting module 5 due to external force or vibration. By equidistantly arranging multiple groups of positioning magnets 46, when the limiting module 5 switches between different angle positions, the same adsorption and positioning force can be obtained for each rotation, ensuring the stability and accuracy of the adjustment process. In addition, the adsorption effect of the positioning magnet 46 can reduce the loosening problem caused by the limiting module 5 not being completely fixed after rotation adjustment, thereby improving the overall stability and reliability of the device.

[0047] See also Fig.10As shown: the limiting module 5 includes a limiting seat 51 that can rotate along the first slide rail 47 and an elastic locking unit 52 that can engage with the groove 43 when the limiting seat 51 rotates to a preset angle; the limiting seat 51 is an arc frame arranged in a semicircular shape; the elastic locking unit 52 is centrally fixed on the limiting seat 51 and arranged close to the edge of the limiting seat 51; the elastic locking unit 52 is provided with a limiting head 521 that always elastically contacts the surface of the limiting seat 51; the edge of the limiting seat 51 is also fixedly provided with an adsorption portion 511, and the adsorption portion 511 is provided with two groups, and the two groups of adsorption portions 511 are symmetrically fixedly arranged on both sides of the limiting seat 51.

[0048] When the two groups of position-limiting clamping modules 4 are synchronously driven by the two groups of pressing modules 3 to synchronously clamp the left roller body 11 and the right roller body 12 to the outside of the rotating shaft 13, thereby completing the assembly of the wire-supporting roller 1, in order to ensure that the left roller body 11 and the right roller body 12 can be firmly locked to the outside of the rotating shaft 13 after being clamped to the outside of the rotating shaft 13, it is only necessary to synchronously drive the two groups of the limiting modules 5 to move clockwise along the set direction until a ninety-degree offset is formed between the limiting surfaces of the two groups of limiting modules 5 and the clamping surfaces of the two groups of position-limiting clamping modules 4. At this time, the limiting head 521 in the elastic locking unit 52 is synchronously ejected and embedded in the corresponding groove 43. The locking of the two groups of position-limiting clamping modules 4 is achieved through the clamping of the limiting head 521 and the groove 43, thereby ensuring the overall stability of the wire-supporting roller 1 after assembly. Similarly, when it is necessary to unlock the two sets of limit clamping modules 4 that have been clamped and locked, it is only necessary to drive the limit module 5 to rotate in the opposite direction so that the limit surface deviates from the ninety-degree locking position, and at the same time, the limit head 521 is disengaged from the groove 43, thereby releasing the locked state and facilitating the disassembly and replacement of the wire support roller 1; the adsorption portion 511 is used to absorb and fix with the magnet embedded in the surface of the clamping seat 42 when rotating to different angles, so that the two sets of limit modules 5 can be limited to different angles.

[0049] See also Figure 6As shown: the elastic locking unit 52 includes a limit frame 522, a guide frame 523, a guide rod 524, a support spring 525 and a handle 526; the limit frame 522 is centrally fixed on the limit seat 51 and is arranged close to the edge of the limit seat 51; the limit head 521 is slidably arranged in the limit frame 522 and the limit end of the limit head 521 passes through the limit seat 51 and abuts against the clamp seat 42; the guide frame 523 is vertically arranged on the surface of the limit seat 51 and is located on the limit frame 522 The guide rods 524 are provided with two, and the two groups of guide rods 524 are relatively vertically arranged on the upper surface of the limiting head 521 and are respectively arranged near the two ends of the limiting head 521; the rod parts of the two guide rods 524 are both arranged through the guide frame 523 and slidingly cooperate with the guide frame 523; the two guide rods 524 are also coaxially sleeved with a supporting spring 525, one end of the supporting spring 525 abuts against the surface of the limiting head 521, and the other end of the supporting spring 525 abuts against the guide frame 523.

[0050] In the non-working state, the limiting head 521 is always in close contact with the surface of the clamping seat 42 at its limiting end under the continuous elastic force of the supporting spring 525. When the staff rotates the limiting seat 51, the limiting head 521 moves along a predetermined trajectory under the synchronous drive of the limiting seat 51 until the limiting head 521 gradually approaches the groove 43. When the limiting seat 51 is accurately rotated to a predetermined locking angle, the limiting head 521 is automatically ejected into the groove 43 under the continuous action of the supporting spring 525, and forms a stable interlocking connection with the groove 43, thereby realizing the locking of the two sets of limiting clamping modules 4, ensuring that the left roller body 11 and the right roller body 12 can be stably fixed after being clamped to the outside of the rotating shaft 13 to prevent accidental loosening.

[0051] When it is necessary to release the lock of the two sets of limit clamping modules 4, the staff only needs to hold the handle 526 and apply external force to make the limit head 521 overcome the elastic force of the support spring 525 and disengage from the groove 43, and at the same time synchronously rotate the limit seat 51 to make the limit surface of the limit module 5 gradually rotate to be flush with the clamping surface of the limit clamping module 4, so as to release the locking state of the limit clamping module 4 and realize the rapid disassembly and replacement of the wire support roller 1.

[0052] The present invention realizes the rapid locking and unlocking operation of the limit clamping module 4 through the linkage structure of the limit seat 51 and the limit head 521, combined with the automatic reset function of the support spring 525, avoids the cumbersomeness of the traditional device relying on additional fasteners for assembly, and improves the disassembly and assembly efficiency.

[0053] See also Figures 7 to 9As shown: the pressing module 3 includes a fixed frame 31, a first linear reciprocating drive 32, a slider 33, a second linear reciprocating drive 34, a connecting frame 35, a guide slide 36 and a sliding quick release 37; the fixed frame 31 is fixedly arranged at one end of the base frame 2 in a vertical state; the first linear reciprocating drive 32 is slidably arranged on the fixed frame 31 in a horizontal state through the slider 33, and the output shaft of the first linear reciprocating drive 32 passes through the fixed frame 31 and is arranged vertically toward the ground; the second linear reciprocating drive 34 is fixedly arranged at the far end of the fixed frame 31 in a horizontal state through the connecting frame 35, and the output shaft of the second linear reciprocating drive 34 passes through the fixed frame 31 and is arranged toward the first linear reciprocating drive 32; the guide slide 36 is fixedly arranged at the driving end of the second linear reciprocating drive 34 in a vertical state; the sliding quick release 37 is fixedly arranged at the driving end of the first linear reciprocating drive 32, and the side of the sliding quick release 37 close to the guide slide 36 is slidably matched with the guide slide 36.

[0054] When it is necessary to separate the two groups of limit clamping modules 4, firstly, the two groups of limit clamping modules 4 are driven to adjust to a vertical posture through an external driving device to ensure the accuracy of subsequent operations. Then, the second linear reciprocating drive 34 is driven to operate so that its output shaft extends in a preset direction, and at the same time, the guide slide 36 and the sliding quick release 37 mechanism are driven to approach the two groups of limit clamping modules 4 synchronously, and the side wall of the sliding quick release 37 is slightly abutted against the side wall of the clamping head 41. Since the pressing module 3 is provided with two groups, under the synchronous abutment correction action of the two groups of pressing modules 3, the limit clamping module 4 is pushed to a stable vertical posture, providing accurate positioning for subsequent disassembly work.

[0055] Next, the output shaft of the second linear reciprocating drive 34 contracts according to the preset stroke, firstly moving the sliding quick release 37 away from the clamping head 41, and then cooperating with the action of the first linear reciprocating drive 32 to move the sliding quick release 37 along the guide rail to the bottom of the clamping head 41. At this time, the second linear reciprocating drive 34 is started, driving the sliding quick release 37 to accurately align to the bottom of the clamping head 41. After the positioning is completed, the first linear reciprocating drive 32 is activated again, driving the sliding quick release 37 to rise in the vertical direction until the sliding quick release 37 forms a reliable clamping connection with the clamping head 41, thereby realizing the buckling operation of the limit clamping module 4.

[0056] Finally, the second linear reciprocating drive 34 is driven to cause its output shaft to contract axially, thereby pulling the two sets of limit clamping modules 4 apart in opposite directions through the action of the sliding quick release 37 mechanism, thereby achieving synchronous separation of the left roller body 11 and the right roller body 12 and completing the disassembly process.

[0057] See also Fig. 9As shown: the sliding quick release 37 includes a rectangular block 371, a second slide rail 372 and a second slot 373; the second slot 373 is fixedly arranged on a side of the rectangular block 371 close to the clamping head 41; and the structure of the second slot 373 matches the clamping head 41 for realizing a snap-fit ​​fit; the second slide rail 372 extends along the length direction of the rectangular block 371, and is fixedly arranged on a side of the rectangular block 371 close to the guide slide 36, and the second slide rail 372 is slidably fitted with the guide slide 36.

[0058] Since the structural shape of the second card slot 373 matches the card head 41, when the first linear reciprocating driver 32 drives the sliding quick release 37 to move along the set trajectory toward the card head 41, the second card slot 373 can be accurately aligned with the card head 41 and smoothly engaged during the final approach process. This matching buckle connection method not only ensures high precision during the installation process and avoids assembly deviations caused by alignment errors, but also improves the stability and reliability of the left roller body 11 and the right roller body 12 during the installation process. Finally, the left roller body 11 and the right roller body 12 can be installed and positioned quickly and accurately, improving assembly efficiency and reducing installation errors.

[0059] A quick-change wire supporting method for enameled wire coating is applied to a quick-change wire supporting device for enameled wire coating, and is characterized in that it comprises the following steps: S1: In the non-installed state, the left roller body 11 and the right roller body 12 are respectively located at the limit ends of the two groups of pressing modules 3 and the two groups of limit clamping modules 4, and are relatively horizontally arranged to ensure that the left roller body 11 and the right roller body 12 are in a pre-aligned state; S2: When the left roller body 11 and the right roller body 12 need to be clamped outside the rotating shaft 13, the second linear reciprocating drivers 34 in the two sets of pressing modules 3 are firstly synchronously driven to extend their output shafts, thereby simultaneously driving the left roller body 11 and the right roller body 12 to approach each other precisely along opposite tracks until the two coaxially clamp the rotating shaft 13, forming a complete wire-supporting roller 1 and being in a preset working position; S3: To ensure that the left roller body 11 and the right roller body 12 are stably fixed after clamping, the staff synchronously drives the two sets of limiting modules 5 to rotate them to a preset locking angle; when the offset angle between the limiting surfaces of the two sets of limiting modules 5 and the clamping surfaces of the two sets of position-limiting clamping modules 4 is adjusted to 90°, the limiting head 521 will be accurately embedded in the groove 43 under the action of the supporting spring 525, thereby locking the two sets of position-limiting clamping modules 4, thereby preventing loosening or offset during operation; S4: Finally, the first linear drive is driven to extend its output shaft, pushing the sliding quick release 37 away from the clamping head 41 until the sliding quick release 37 is completely separated from the clamping head 41, thereby realizing the rapid replacement of the wire support roller 1.

[0060] The present invention can realize efficient replacement of the wire supporting roller without disassembling the machine, and has high replacement efficiency and good effect.
