The reel baking jig includes:

[0046] A bottom plate 1, the bottom plate 1 includes a plate body 101, and a plurality of nuts 102 are fixedly arranged inside the plate body 101;

[0047] A cover plate 2, the cover plate 2 includes a cover body 21, a plurality of positioning blocks 23 are fixedly arranged on the cover body 21, a threaded hole is opened at the center of the positioning block 23, and a fixing member 6 is threadedly connected to the positioning block 23;

[0048] A correction block 3, the correction block 3 includes a first correction half block 31 and a second correction half block 32, locking members 5 are arranged on both the upper and lower sides of the first correction half block 31, and positioning members 7 are fixedly connected to both the upper and lower sides of the second correction half block 32;

[0049] Assembly holes are provided at the centers of the bottom plate 1, the cover plate 2, and the correction stoppers 3.

[0050] The number of the positioning blocks 23 and the nuts 102 is preferably four and they are arranged in corresponding positions. The assembly holes at the centers of the bottom plate 1, the cover plate 2, and the correction stoppers 3 are used to sleeve the winding shaft at the center of the reel. Semicircular grooves are provided at the centers of the first correction half-block 31 and the second correction half-block 32;

[0051] Through holes are provided on the bottom plate 1 corresponding to the inner circles of the nuts 102, through holes are also provided on the cover plate 2 corresponding to the threaded holes of the positioning blocks 23, and a plurality of circular holes are provided on the correction stoppers 3. When fixed to the reel, the positioning shaft 61 can pass through the circular holes on the correction stoppers 3.

[0052] A positioning ring 104 is fixedly connected to the outside of the bottom plate 1 corresponding to the position of the nut 102, and two first reinforcing bars 103 are symmetrically and fixedly connected to the outside of the bottom plate 1.

[0053] By providing the positioning ring 104, the center of the positioning ring 104 corresponds to the hole at the center of the nut 102. When the positioning shaft 61 is threadedly connected to the nut 102 and the end extends into the positioning ring 104, the positioning shaft 61 can be positioned, improving stability. The first reinforcing bars 103 can strengthen the strength of the bottom plate 1 and greatly reduce the deformation of the bottom plate 1.

[0054] Two second reinforcing bars 22 are symmetrically and fixedly connected to the outside of the cover plate 2.

[0055] The second reinforcing bars 22 enhance the strength of the cover plate 2 and greatly reduce the deformation of the cover plate 2.

[0056] The fixing member 6 includes a positioning shaft 61. One end of the positioning shaft 61 is fixedly connected with a driving handle 62, and threads 63 are provided at both ends of the surface of the positioning shaft 61.

[0057] By providing the driving handle 62, it is convenient to screw the positioning shaft 61, facilitating the fixing and disassembly of the bottom plate 1 and the cover plate 2 by the positioning shaft 61. By providing threads 63 at both ends of the positioning shaft 61, it can be threadedly connected and fixed to the nuts 102 on the bottom plate 1 and the threaded holes on the positioning blocks 23 on the cover plate 2 at the same time, improving the stability after installation and fixing.

[0058] The locking member 5 includes two fixing blocks 51 which are symmetrically fixed to the end of the first correction half block 31. A mounting cylinder 52 is rotatably connected between the two fixing blocks 51. A connecting cylinder 53 is arranged inside the mounting cylinder 52. The top of the connecting cylinder 53 is fixedly connected with a pulling block 59. One end of the pulling block 59 penetrates through the mounting cylinder 52 and extends to the outside of the mounting cylinder 52. The end of the pulling block 59 located outside the mounting cylinder 52 is fixedly connected with a positioning block 510. One side of the positioning block 510 is an arc surface.

[0059] Both ends of the first correction half block 31 and the second correction half block 32 are flat surfaces. Rotating shafts are fixedly arranged on the inner sides of the two fixing blocks 51. Corresponding circular grooves are formed on both sides of the surface of the mounting cylinder 51. The rotating shafts are located inside the circular grooves, thus forming a rotational fit.

[0060] The length value of the connecting cylinder 53 is less than the inner cavity length value of the mounting cylinder 52. By arranging the connecting cylinder 52, the elastic member 54 can be limited during compression, so that it deforms in one direction.

[0061] An elastic member 54 is arranged inside the connecting cylinder 53. Sliding grooves 55 are formed on both sides of the mounting cylinder 52. Connecting rods 56 are fixedly connected to both sides of the surface of the connecting cylinder 53. One end of the connecting rod 56 penetrates through the mounting cylinder 52 through the sliding groove 55. One end of the connecting rod 56 is fixedly connected with a pull ring 58.

[0062] The elastic member 54 is preferably a spring. The length value of the sliding groove 55 is greater than the length value of the positioning block 510. The pull ring 58 facilitates pulling the connecting cylinder 52, compressing the elastic member 54 and driving the pulling block 59 to move into the inside of the mounting cylinder 52, so that the positioning block 510 moves out of the clamping hole 4.

[0063] A stop block 57 is fixedly connected to one side between the two fixing blocks 51.

[0064] When the mounting cylinder 52 rotates to be perpendicular to the end of the first correction half block 31, the stop block 57 can axially limit the mounting cylinder 52. For example, as shown in Figure 6 and Figure 8 it can limit the counterclockwise rotation of the mounting cylinder 52.

[0065] Clamping holes 4 are formed at both ends of the first correction half block 31.

[0066] The clamping hole 4 is adapted to the size of the positioning block 510.

[0067] The positioning member 7 includes an L-shaped fixing block 71, and a strip-shaped cavity 72 is formed on the L-shaped fixing block 71.

[0068] The length value of the strip-shaped cavity 72 is greater than the thickness value of the pulling block 59, and the width value of its groove cavity is the same as the width value of the pulling block 59.

[0069] The working principle of the reel baking fixture provided by the present invention is as follows:

[0070] First, place the bottom plate 1 flat, place the deformed reel correspondingly on the bottom plate 1, and the center of the reel corresponds to the center of the bottom plate 1;

[0071] Then, the center semi-circular parts of the first correction half-block 31 and the second correction half-block 32 are correspondingly buckled on the winding shaft at the center of the reel, and then locked by the locking part 5 and the positioning part 7;

[0072] Next, cover the cover plate 2 correspondingly on the upper side of the reel, and the positioning shaft 61 correspondingly passes through the correction block 3 and the reel, corresponding to the nut 102 on the bottom plate 1, and then fix it by rotating the driving handle 62;

[0073] Then, place the fixed reel into the oven for baking to be re-shaped.

[0074] During the process of buckling the first correction half-block 31 and the second correction half-block 32, the L-shaped fixing block 71 on the second correction half-block 32 is correspondingly inserted between the two fixing blocks 51 and is located above the mounting cylinder 52, and then rotate the mounting cylinder 52 to make it perpendicular to both ends of the first correction half-block 31. During the rotation process, the arc surface of the positioning block 510 acts on the L-shaped fixing block 71, and the positioning block 510 is pushed to drive the pulling block 59, and the pulling block 59 pushes the connecting cylinder 53 to compress the elastic member 54 and enter the interior of the mounting cylinder 52;

[0075] The pulling block 59 enters the strip-shaped cavity 72 on the L-shaped fixing block 71. During the rotation process, the pulling block 59 pulls the L-shaped fixing block 71 to tighten the first correction half-block 31 and the second correction half-block 32. When the mounting cylinder 52 rotates 90 degrees, at this time, the first correction half-block 31 and the second correction half-block 32 are tightened, and at this time, the positioning block 510 corresponds to the position of the card hole 4. Through the action of the elastic member 54, the connecting cylinder 53 is pushed to make the limiting block 510 enter the card hole 4 for limiting. At the same time, one side of the mounting cylinder 52 contacts the stop block 57, as shown in the appendix Figure 6 and Figure 8 In the figure, the stop block 57 can limit the counterclockwise rotation of the mounting cylinder 52, and the positioning block 510 cooperating with the card hole 4 can limit the clockwise rotation of the mounting cylinder 52, so as to limit it, and the operation is simple;

[0076] When disassembling, by pulling the two pull rings 58 in sequence, the pull ring 58 pulls the connecting cylinder 53 through the connecting rod 56, and the connecting cylinder 53 drives the positioning block 510 to move out of the clamping hole through the pulling block 59. Then, rotate the installation cylinder 52 clockwise to make it horizontal, and the first correction half block 31 and the second correction half block 32 can be disassembled.

[0077] Compared with the related art, the coiling baking fixture provided by the present invention has the following beneficial effects:

[0078] By arranging the bottom plate 1, the cover plate 2 and the correction stop block 3 to fix and position the deformed coiling, and then placing it inside the oven to be reshaped, after the deformed coiling is corrected, it can be used for rewinding again. It can avoid product breakage loss during the product coiling process, timely correct and repair the deformed coiling, recycle the rewinding, avoid higher costs for purchasing new products, and save costs;

[0079] Moreover, the installation, fixation and disassembly between the bottom plate 1, the cover plate 2 and the correction stop block 3 and the deformed coiling are all simple and convenient to operate.

[0080] Second Embodiment

[0081] Please refer to FIG. 10 in combination. Based on the coiling baking fixture provided in the first embodiment of the present application, the second embodiment of the present application proposes another coiling baking fixture. The second embodiment is only the preferred manner of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0082] Specifically, the difference of the coiling baking fixture provided in the second embodiment of the present application is that the installation cylinder 52 includes an upper half cylinder 521 and a lower half cylinder 522, and the upper half cylinder 521 and the lower half cylinder 522 are rotatably connected, and the two chutes 55 are opened on both sides of the surface of the lower half cylinder 522.

[0083] The distance value between the two symmetrically arranged pull rings 58 is greater than the distance value between the bottom plate 1 and the cover plate 2 after the coiling is installed. After the locking member 5 locks the correction stop block 3, at this time, the pull ring 58 is parallel to the bottom plate 1 and the cover plate 2.

[0084] By setting the installation cylinder 52 as an upper half cylinder 521 and a lower half cylinder 522, when the deformed reel is reshaped, when taking out the mold, first unscrew the positioning shaft 61 by twisting the driving handle 62, and then the lower half cylinder 522 located at both ends of the first correction half block 31 can be rotated, and the lower half cylinder 522 drives the two connecting rods 56 to rotate through the slide grooves 55 on both sides, and the connecting rod 56 drives the pull ring 58 to rotate. While the pull ring 58 rotates, it can push the bottom plate 1 and the cover plate 2 to both sides, thereby facilitating the separation of the bottom plate 1 and the cover plate 2 from the reel (the surface of the reel softens during baking, and there is a situation where the reel adheres to the inner side of the bottom plate 1 and the cover plate 2, which is not convenient for demolding)

[0085] Third embodiment

[0086] Please refer to Figure 11 Based on the roll baking jig provided in the first embodiment of the present application, the third embodiment of the present application proposes another roll baking jig. The third embodiment is only a preferred embodiment of the first embodiment, and the implementation of the third embodiment will not affect the independent implementation of the first embodiment.

[0087] Specifically, the coil baking jig provided in the second embodiment of the present application is different in that the coil baking jig further includes a locking mechanism for fixing the bottom plate 1 and the cover plate 2, the locking mechanism includes a connecting frame 81, and positioning posts 82 are passed through the four corners of the connecting frame 81, and retaining rings 83 are fixedly connected on both sides of the surface of the positioning post 82 and located on the upper and lower sides of the connecting frame 81, and external threads are provided on both sides of the surface of the positioning post 82;

[0088] The retaining ring 83 can limit the horizontal direction of the positioning column 82, and the positioning column 82 can rotate axially.

[0089] One end of the positioning column 82 is fixedly connected to a transmission wheel 84 , and a plurality of the transmission wheels 84 are transmission-connected via a transmission belt 85 , and one side of one of the transmission wheels 84 is fixedly connected to a driving shaft 86 .

[0090] The two external threads on the surface of the positioning column 82 are both located on one side of the retaining ring 83. The transmission wheel 84 and the transmission belt 85 can be a pulley and a belt, or a gear and a toothed belt. When it is a gear, flanges are provided on both sides of the gear to protect the toothed belt.

[0091] The four positioning posts 82 correspond to the positions of the nuts 102 on the bottom plate 1 and the positioning blocks 23 on the cover plate 2;

[0092] When the bottom plate 1, the cover plate 2 and the correction stop block 3 are correspondingly installed on the reel, the four positioning columns 82 are correspondingly passed through the threaded holes on the positioning block 23 and the correction stop block 3, and then are threadedly fixed to the nuts 102 on the bottom plate 1. Among them, by rotating the driving shaft 86 on the driving wheel 84, through the action of the transmission belt 85, rotating one driving wheel 84 can drive the four positioning columns 82 to rotate simultaneously, that is, by threadedly fixing one positioning column 82 to the nut 102, the other three are fixed simultaneously. At the same time, when disassembling, turning one driving wheel 84 can disassemble the entire locking mechanism at the same time. The installation and disassembly operation is simple, and there is no need to tighten and fix one by one, improving the installation efficiency.

[0093] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
