Description

Technical Field

[0001] This utility model relates to the field of abrasive belt production technology, specifically a material roll unwinding frame. Background Technology

[0002] In the production of abrasive belts, the unwinding of the abrasive belt rolls is a crucial step, directly affecting the continuity, stability, and production efficiency of subsequent processing. As the core equipment for supporting and smoothly unwinding the rolls, the structural design and functional adaptability of the unwinding frame have a significant impact on overall production efficiency.

[0003] Currently, most unwinding frames are single-layer, single-roller structures that can only carry a single complete roll. When the roll is used up, the machine needs to be stopped to replace it with a new roll. Frequent shutdowns and roll replacements can lead to production interruptions and significantly reduce production continuity. In particular, in mass production scenarios, the efficiency loss caused by the accumulated time spent on roll replacements is even more significant. Therefore, we need to propose a roll unwinding frame. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a material roll unwinding frame, including a support frame 1, and the support frame 1 is provided in two sets. An extension plate 2 is integrally formed on the upper surface of the support frame 1. A placement component for placing defective material rolls is installed at the top of the extension plate 2. An adjustment frame 3 is welded and fixed at the top and bottom of the support frame 1. An adjustment structure for adjusting the support distance of the material roll is provided in the inner cavity of the adjustment frame 3. An installation seat 4 is provided at the top of the adjustment structure. A connecting groove 5 is opened on the surface of the installation seat 4. An unwinding roller 6 for connecting with the material roll is provided between the two sets of installation seats 4. The two sides of the unwinding roller 6 are rotatably connected to the inner cavity of the connecting groove 5 through bearings. Several sets of adjustment frames 3 are provided, and several sets of adjustment frames 3 are equally distributed on the surface of the support frame 1.

[0023] In use, several sets of material rolls are assembled with the unwinding roller 6 in sequence. Then, the positions of the mounting seats 4 on both sides are adjusted by adjusting the structure so that the connecting grooves 5 on the mounting seats 4 are assembled with the unwinding roller 6, thereby installing the unwinding roller 6 onto the unwinding frame. Through the cooperation of several sets of adjusting frames 3 and the unwinding roller 6, several sets of material rolls can be installed on the unwinding frame. When defective material rolls appear during unwinding, they can be stored in the placement component. Defective material rolls are classified and carried separately from normal unwinding material rolls to avoid mixing and contamination. When reused, they can be directly taken out. The above solution avoids production interruption caused by roll changing operations, improves the continuity of material roll production, avoids the time occupied by roll changing operations, and improves the roll changing speed.

[0024] The adjustment structure includes a self-locking screw 7 located inside the adjustment frame 3. The self-locking screw 7 is rotatably connected to the inner wall of the adjustment frame 3 via a bearing. One end of the self-locking screw 7 passes through the adjustment frame 3 and is welded and fixed to a turntable 8. An adjustment seat 9 is provided on the surface of the self-locking screw 7. The top end of the adjustment seat 9 is bolted to the bottom end of the mounting seat 4. Rotating the turntable 8 drives the self-locking screw 7 to rotate. The rotation of the self-locking screw 7 drives the adjustment seat 9 to move, which in turn drives the mounting seat 4 to move, thereby adjusting the position of the mounting seats 4 on both sides. This allows for the installation and removal of the unwinding roller 6.

[0025] The surface of the adjusting seat 9 is integrally formed with a threaded seat 10 that is compatible with the self-locking screw 7. Both sides of the adjusting seat 9 are provided with through holes. The inner cavity of the through hole of the adjusting seat 9 is slidably connected with a slide rod 11. Both ends of the slide rod 11 are welded and fixed to the inner side wall of the adjusting frame 3. Through the cooperation of the threaded seat 10 and the self-locking screw 7, rotating the self-locking screw 7 drives the threaded seat 10 to move through the thread, so that the threaded seat 10 drives the adjusting seat 9 to move. The adjusting seat 9 drives the mounting seat 4 at the top to move, thereby adjusting the position of the mounting seat 4. The slide rod 11 can support both sides of the adjusting seat 9, providing a guiding function for the movement of the adjusting seat 9 and improving the stability of the adjusting seat 9 when it moves.

[0026] A rotating rod 12 is provided on the surface of the mounting base 4. The rotating rod 12 is rotatably connected to the surface of the mounting base 4 through a bearing. A turntable 13 is welded and fixed to one end of the rotating rod 12, and a rotating seat 14 is welded and fixed to the other end of the rotating rod 12 through the mounting base 4. The rotating seat 14 is located in the inner cavity of the connecting groove 5. When the mounting bases 4 on both sides move inward, the connecting groove 5 is combined with the unwinding roller 6. When the surface of the rotating seat 14 is in contact with the unwinding roller 6, the friction force on the unwinding roller 6 is increased. Rotating the turntable 13 can drive the rotating seat 14 to rotate through the rotating rod 12. The rotating seat 14 drives the unwinding roller 6 to rotate, which can realize the auxiliary unwinding operation of the material roll.

[0027] The inner cavity of the support frame 1 is welded and fixed with a support beam 15. The support beam 15 is Y-shaped. Between the two sets of support beams 15, there is a support rod 16 for supporting the material roll. Both ends of the support rod 16 are welded and fixed to the inner side wall of the support beam 15. There are several sets of support rods 16, and the several sets of support rods 16 are evenly distributed at the top and bottom of the support beam 15. Through the multiple sets of distributed support rods 16, a stable guiding support is formed for the material roll during the unwinding process, which effectively avoids the material roll from shifting or wrinkling during unwinding, ensures the consistency of the material roll conveying direction, and further improves the smoothness of the unwinding operation.

[0028] The placement assembly includes a connecting frame 17 welded to the top of the extension plate 2. A slide block 18 is slidably connected to the inner cavity of the connecting frame 17. A positioning seat 19 is bolted to the top of the slide block 18. An installation groove is provided on the inner side wall of the positioning seat 19. A placement roller 20 for placing the material roll is provided between the two sets of positioning seats 19. The placement roller 20 is rotatably connected to the inner cavity of the installation groove through a bearing. The defective material roll is assembled with the placement roller 20. Then, the placement roller 20 is moved between the two sets of positioning seats 19, pushing the slide block 18 to drive the positioning seats 19 on both sides to move inward. The installation groove on the positioning seat 19 combines with the placement roller 20 to realize the installation of the placement roller 20.

[0029] The inner wall of the connecting frame 17 is provided with a sliding groove, and the inner cavity of the sliding groove is slidably connected to the slider 21. The slider 21 is welded and fixed to the surface of the slide block 18. The cooperation between the sliding groove and the slider 21 can support the two sides of the slide block 18, provide guidance for the movement of the slide block 18, prevent the angle of the slide block 18 from deviating when it moves, and improve the stability of the slide block 18 when it moves.

[0030] The top of the connecting frame 17 is provided with a fixing hole 22. The inner cavity of the fixing hole 22 is slidably connected with a positioning pin 23. The surface of the slider 21 is provided with a positioning hole 24 that matches the positioning pin 23. When the slide 18, along with the positioning seat 19, is combined with the placement roller 20, the position of the positioning hole 24 on the slider 21 is aligned with the position of the fixing hole 22. At this time, it is only necessary to take out the positioning pin 23, insert it into the inner cavity of the fixing hole 22 and extend it into the positioning hole 24 to position the slider 21 and prevent the slider 21 from shifting during operation.

[0031] In practical use: Assemble the material roll with the unwinding roller 6, then move the assembled unwinding roller 6 between the two sets of mounting seats 4. Then, rotate the turntable 8 to drive the self-locking screw 7 to rotate. The self-locking screw 7 drives the threaded seat 10 through the thread to drive the adjusting seat 9 to move, so that the adjusting seat 9 drives the mounting seats 4 on both sides to move inward. When the connecting groove 5 on the mounting seat 4 and the unwinding roller 6 are inserted, the assembly operation of the unwinding frame and the material roll is completed. Then, assemble several sets of material rolls with the unwinding roller 6 in sequence using the above method. Then assemble several sets of assembled unwinding rollers 6 with several sets of mounting seats 4, thus realizing the assembly operation of several sets of material rolls with the unwinding frame.

[0032] When a defective coil appears during unwinding, the reverse turntable 8 drives the self-locking screw 7 to rotate. The self-locking screw 7 drives the adjusting seat 9 to move outward within the adjusting frame 3 via the threaded seat 10, causing the mounting seat 4 to move away from the unwinding roller 6. The unwinding roller 6 moves out of the inner cavity of the connecting groove 5, allowing the unwinding roller 6 to be disassembled. Then, the defective coil is removed from the unwinding roller 6 and installed on the placement roller 20. The placement roller 20 is moved between the two sets of positioning seats 19, pushing the slide 18 to drive the positioning seats 19 on both sides to move inward. The mounting groove on the positioning seat 19 combines with the placement roller 20. When the slide 1... 8. After the positioning seat 19 and the placement roller 20 are in place, the position of the positioning hole 24 on the slider 21 is aligned with the position of the fixing hole 22. At this time, it is only necessary to take the positioning pin 23, insert it into the inner cavity of the fixing hole 22 and extend it into the positioning hole 24 to position the slider 21. This realizes the distinction between defective and normal material rolls on the unwinding frame. When defective material rolls are needed, they can be unwound directly on the unwinding frame. The above solution avoids production interruption caused by roll changing operations, improves the continuity of material roll production, avoids the time occupied by roll changing operations, and improves the roll changing speed.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
