Technical Field
[0001] This utility model relates to the field of quilting machine technology, specifically to a roller support structure for a quilting machine with a gap adjustment structure. Background Technology
[0002] A quilting machine is a type of textile machinery that sews linear patterns onto the surface of fabric. It features seamless, spliced-free operation and high processing efficiency. The rollers of the quilting machine are an important component of the textile machinery. They are made of high-quality steel and have high strength and rigidity. Their function is to support and transmit, control and transport cotton threads. The roller support structure is the component that supports the rollers.
[0003] Traditional quilting machine roller support structures rely on multiple rollers to control and transport the cotton thread. Depending on the specific production requirements, different gaps are needed between these rollers. Therefore, we propose a roller support structure with adjustable gaps to address these issues. Utility Model Content
[0004] The purpose of this invention is to provide a roller support structure for a quilting machine with a gap adjustment structure, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a roller support structure for a quilting machine with a gap adjustment structure, comprising a first plate, a second plate disposed on one side of the first plate, both the first and second plates having adjustment grooves inside, a roller body movably disposed between the first and second plates, a first shaft fixed to the left side of the roller body, a first mounting seat movably disposed on the outer side wall of the first shaft, a second shaft fixed to the right side of the roller body, and a second mounting seat movably disposed on the outer side wall of the second shaft, a pulley mounted on the right side of the second shaft, threaded grooves disposed at the top of the interior of both the first and second mounting seats, threaded columns movably disposed inside the threaded grooves, a fixing rod fixed to the top of the threaded column, a rotating block fixed to the top of the fixing rod, and fixing holes disposed on the exterior of the fixing rod, the fixing holes being located at the top of the interior of the first and second plates.
[0006] As a further technical solution of this utility model, the inner sidewall of the threaded groove is uniformly provided with internal threads, and the threaded groove and the threaded column form a threaded connection.
[0007] As a further technical solution of this utility model, a plurality of fixing holes are provided, and the plurality of fixing holes are distributed at equal intervals at the top ends of the first plate and the second plate.
[0008] As a further technical solution of this utility model, both the first mounting base and the second mounting base are provided with rolling grooves, and rolling balls are movably arranged inside the rolling grooves.
[0009] As a further technical solution of this utility model, a plurality of balls are provided, and the plurality of balls are arranged in a ring inside the first mounting base and the second mounting base.
[0010] As a further technical solution of this utility model, a connecting block is fixed at the front end of both the first plate and the second plate. A threaded rod is movably arranged inside the connecting block, and a handle is installed on the right side of the threaded rod via a rotating shaft. A threaded block is movably arranged on the outer wall of the threaded rod. A cleaning brush rod is fixed at the front end of the threaded block. A guide block is fixed at the front end of the cleaning brush rod. A guide groove is provided inside the guide block. A guide rod is movably arranged inside the guide groove, and both sides of the guide rod are fixed to one side of the first plate and the second plate, respectively.
[0011] As a further technical solution of this utility model, the inner sidewall of the threaded block is uniformly provided with internal threads, and the threaded block and the threaded rod form a threaded connection.
[0012] As a further technical solution of this utility model, the cross-section of the guide block is larger than the cross-section of the guide rod, and the guide block and the guide rod form a sliding structure through the guide groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the roller support structure of the quilting machine not only makes it easy to adjust the gap between the rollers, making the rollers rotate more smoothly, but also makes it easier to clean the rollers;
[0014] When using this roller support structure, if it is necessary to adjust the distance between the internal rollers, the addition of components such as a first mounting seat, a second mounting seat, a fixing rod, and a threaded column allows for convenient and quick adjustment of the gap between the rollers when they are installed inside the support structure. This makes the support structure more convenient for adjusting the gap between the rollers and more easy to use.
[0015] After a certain period of use, the rollers installed inside the support structure need to be cleaned. This requires brushing each roller individually. By incorporating components such as threaded rods, threaded blocks, and cleaning brush rods inside the first and second plates, it is convenient to clean multiple rollers simultaneously, saving cleaning time and enabling the support structure to facilitate quick cleaning of the rollers.
[0016] By incorporating components such as rolling grooves and ball bearings, when the roller body rotates during use, the first and second shafts on both sides of the roller body rotate within the first mounting base and the first plate, respectively. Because rotatable ball bearings are installed inside the first and second mounting bases, the rotation of the first and second shafts within the first mounting base and the first plate converts sliding friction into rolling friction, thereby making the roller body rotate more smoothly during use.

[0022] 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.
[0023] Please see Figure 1-4This utility model provides an embodiment: a roller support structure for a quilting machine with a gap adjustment structure, including a first plate 1, a second plate 13 disposed on one side of the first plate 1, and adjustment grooves 20 disposed inside both the first plate 1 and the second plate 13. A roller body 6 is movably disposed between the first plate 1 and the second plate 13. A first shaft 3 is fixed to the left side of the roller body 6, and a first mounting seat 2 is movably disposed on the outer side wall of the first shaft 3. A second shaft 12 is fixed to the right side of the roller body 6, and a second mounting seat 11 is movably disposed on the outer side wall of the second shaft 12. A pulley 10 is mounted on the right side of the second shaft 12. Threaded grooves 22 are disposed at the top of the interior of both the first mounting seat 2 and the second mounting seat 11. The interior of each of the 22 is equipped with a threaded post 21, and the top of each threaded post 21 is fixed with a fixing rod 19. The top of each fixing rod 19 is fixed with a rotating block 4. The exterior of each fixing rod 19 is provided with a fixing hole 18, which is located at the top of the interior of the first plate 1 and the second plate 13. The inner sidewall of the threaded groove 22 is uniformly provided with internal threads. The threaded groove 22 and the threaded post 21 form a threaded connection. The threaded connection design facilitates the stable locking of the first mounting seat 2 and the second mounting seat 11. Several fixing holes 18 are provided, and the several fixing holes 18 are distributed at equal intervals at the top of the interior of the first plate 1 and the second plate 13, which facilitates the adjustment of the roller body 6 to different positions, so that there are gaps of different sizes between them.
[0024] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, when adjusting the gap between multiple roller bodies 6, rotate the rotating block 4 so that the ball bearing 24 at its bottom end moves out of the threaded groove 22 inside the first mounting seat 2 and the second mounting seat 11. Then, pull the fixing rod 19 upward so that it moves out of the fixing hole 18. Next, push the first mounting seat 2 and the second mounting seat 11 on both sides of the roller body 6 to the appropriate position in the adjustment groove 20 inside the first plate 1 and the second plate 13 according to actual needs. Then, take the rotating block 4 and pass the fixing rod 19 at its bottom end through the corresponding fixing hole 18 so that the threaded post 21 at its bottom end is screwed into the threaded groove 22 inside the first mounting seat 2 and the second mounting seat 11, thereby fixing the roller body 6 with the adjusted gap for use.
[0025] A connecting block 25 is fixed to the front end of both the first plate 1 and the second plate 13. A threaded rod 5 is movably arranged inside the connecting block 25, and a handle 8 is installed on the right side of the threaded rod 5 through a rotating shaft 9. A threaded block 7 is movably arranged on the outer wall of the threaded rod 5. A cleaning brush rod 14 is fixed to the front end of the threaded block 7. A guide block 17 is fixed to the front end of the cleaning brush rod 14. A guide groove 16 is provided inside the guide block 17. A guide rod 15 is movably arranged inside the guide groove 16. The two sides of the guide rod 15 are fixed to one side of the first plate 1 and the second plate 13, respectively. The inner side wall of the threaded block 7 is uniformly provided with internal threads. The threaded block 7 and the threaded rod 5 form a threaded connection. The cross-section of the guide block 17 is larger than the cross-section of the guide rod 15. The guide block 17 and the guide rod 15 form a sliding structure through the guide groove 16. The threaded connection design can drive the cleaning brush rod 14 to move stably.
[0026] Specifically, such as Figure 1 and Figure 4 As shown, when cleaning the roller body 6, the throttle 8 is turned to make the threaded rod 5 rotate. When the threaded rod 5 rotates, the threaded block 7 on its outer side wall drives the cleaning brush rod 14 from one side of the roller body 6 to the other side through the guide rod 15 to guide the guide block 17, and clean the rotating roller body 6 by brushing.
[0027] Both the first mounting base 2 and the second mounting base 11 are provided with rolling grooves 23, and rolling balls 24 are movably arranged inside the rolling grooves 23. Several rolling balls 24 are arranged in a ring inside the first mounting base 2 and the second mounting base 11, so that the rotation of the first shaft 3 inside the first mounting base 2 and the rotation of the second shaft 12 inside the second mounting base 11 are smoother.
[0028] Specifically, such as Figure 2 and Figure 3 As shown, the rotation of the first shaft 3 inside the first mounting base 2 and the rotation of the second shaft 12 inside the second mounting base 11 are affected by the addition of multiple balls 24. This causes the sliding friction of the first shaft 3 and the second shaft 12 inside the first mounting base 2 and the second mounting base 11 to become rolling friction, thereby enabling the first shaft 3 and the second shaft 12 to smoothly rotate the auxiliary roller body 6.
[0029] Working principle: In use, the roller body 6 is installed inside the first plate 1 and the second plate 13 via the first mounting seat 2 and the second mounting seat 11. Then, the external transmission device drives the roller body 6 to rotate with the assistance of the pulley 10 to control and transport the cotton thread. When using the roller body 6, if it is necessary to adjust the gap of the roller body 6, rotate the rotating block 4 so that the ball 24 at its bottom end moves out of the threaded groove 22 inside the first mounting seat 2 and the second mounting seat 11. Then, pull the fixing rod 19 upward so that it moves out of the fixing hole 18. Then, according to the actual needs, push the first mounting seat 2 and the second mounting seat 11 on both sides of the roller body 6 to the appropriate position inside the adjustment groove 20. Then, take out the fixing rod 19 and pass it through the corresponding fixing hole 18 above the first mounting seat 2 and the second mounting seat 11 after adjusting the position. Screw the threaded post 21 at the bottom end of the fixing rod 19 into the threaded groove 22 to fix the first mounting seat 2 and the second mounting seat 11, thereby adjusting the gap between the roller bodies 6 for use.
[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
