Description
Technical Field
[0001] This application relates to the field of paper roll rewinding machines, and in particular to an automatic paper roll rewinding machine and its processing method that facilitates paper roll replacement. Background Technology
[0002] A rewinding machine is an auxiliary device in the textile industry used to rewind yarn in one package form (such as tube yarn, skein yarn, cone yarn, etc.) into another form or specification of cone yarn.
[0003] See Chinese Utility Model Patent No. CN221070426U, which discloses a yarn turning machine for yarn production and processing, including a base plate, a left side plate and a right side plate respectively installed on the upper end surface of the base plate, a fixing plate evenly installed at equal intervals on the side wall of the left side plate, a fixing rod connected to one end of the fixing plate, and a locking structure provided on the outside of the fixing rod, a connecting seat symmetrically installed on the side wall of the right side plate, a roller connected between the two connecting seats, and a finished yarn bobbin fitted on the outside of the roller, and a connecting structure provided at the connection between one of the connecting seats and the right side plate.
[0004] In actual use, this type of paper roll rewinding machine takes a long time to change the paper roll and restart the machine, resulting in low replacement efficiency, which needs to be improved. Summary of the Invention
[0005] To reduce the time spent in the process of changing paper tubes and restarting the rewinding machine, this application provides an automatic rewinding machine and its processing method that facilitates paper tube replacement.
[0006] This application provides an automatic paper roll rewinding machine that facilitates paper roll replacement, employing the following technical solution:
[0007] An automatic paper tube rewinding machine for easy paper tube replacement includes a machine body, which is provided with a yarn guiding assembly and a mounting frame. The yarn guiding assembly is used to guide the movement of the yarn. The machine body is provided with a grooved tube. The mounting frame is provided with a rotating rod, which includes a spindle rod and a mounting rod. The mounting rod rotates on the mounting frame and is used to fix the paper tube. The mounting frame is provided with a sliding spring, and the mounting rod is provided with a sliding sleeve. The end of the sliding spring away from the mounting frame is used to abut against the sliding sleeve. The sliding sleeve slides on the mounting rod, and the sliding direction of the sliding sleeve is the axial direction of the mounting rod. The sliding sleeve is provided with a sliding hole, which passes through the sliding sleeve and allows the spindle rod to be inserted. The wall of the sliding hole is provided with a snap-fit element, which is used to connect the spindle rod. When the spindle rod is inserted into the sliding hole, the snap-fit element causes the sliding sleeve to rotate, which in turn drives the spindle rod to rotate.
[0008] By adopting the above technical solution and setting a sliding sleeve and a sliding spring, when paper tube needs to be replaced, the paper tube is pre-fixed to the spindle rod. When installing the spindle rod, the sliding sleeve is moved to provide clearance space, which makes it easier for the spindle rod to be inserted into the sliding hole. This facilitates the connection of the spindle rod with the snap-fit parts, and makes it easier for the subsequent installation rod to rotate, indirectly driving the spindle rod to rotate. This reduces the time spent in the step of replacing the paper tube and restarting the rewinding machine.
[0009] Optionally, the snap-fit component includes a snap-fit protrusion, the extension direction of which is parallel to the axial direction of the mounting rod, and the spindle is provided with a snap-fit groove for the snap-fit protrusion to be inserted.
[0010] By adopting the above technical solution, a snap-fit protrusion and a snap-fit groove are set. When the snap-fit protrusion is embedded in the snap-fit groove, the connecting sleeve rotates and drives the spindle to rotate, which facilitates the installation of the spindle and improves the efficiency of the spindle installation operation.
[0011] Optionally, the sliding hole wall is provided with a pre-clamping area, which is located on the side of the sliding sleeve away from the mounting bracket, and the clamping protrusion extends to the side of the pre-clamping area close to the mounting bracket.
[0012] By adopting the above technical solution, in actual use, there is a situation where the locking protrusion and the locking groove are misaligned when the spindle is inserted. Therefore, a pre-locking area is set so that the spindle stops in the pre-locking area. At this time, the sliding spring is in a compressed state. When the driving component drives the mounting rod to rotate the sliding sleeve, the locking groove corresponds to the locking protrusion. At this time, the elastic force of the sliding spring causes the sliding sleeve to move, and the locking protrusion is embedded in the locking groove, thereby driving the spindle to rotate.
[0013] Optionally, the mounting rod has a fixing groove on its peripheral wall, a fixing block is provided in the fixing groove, the fixing block slides in the fixing groove, the sliding direction of the fixing block is away from the bottom of the fixing groove, and the sliding hole wall has a positioning groove for the fixing block to be embedded in.
[0014] By adopting the above technical solution and setting a fixing block, when the mounting rod is not rotated, the fixing block is located in the fixing groove, and the sliding sleeve can slide along the axis of the mounting rod. When the mounting rod rotates, the fixing block is thrown out from the fixing groove and embedded in the positioning groove, thereby restricting the movement of the sliding sleeve along the axis of the mounting rod and reducing the impact of the sliding sleeve on the normal operation of the machine.
[0015] Optionally, a fixing spring is provided at the bottom of the fixing groove. One end of the fixing spring is connected to the fixing block, and the other end is connected to the bottom of the fixing groove. The elastic force of the fixing spring restricts the fixing block from moving away from the bottom of the fixing groove.
[0016] By adopting the above technical solution, a fixing spring is set to return the fixing block to its original position, thereby reducing its influence on the movement of the sliding sleeve after the mounting rod stops rotating.
[0017] Optionally, the bottom of the positioning groove is provided with a positioning magnet, and the fixing block is a fixing magnet. The magnetic force of the fixing magnet and the magnetic force of the positioning magnet are repelled. When the mounting rod rotates, the fixing block moves to the positioning groove and restricts the sliding sleeve from moving along the axis of the mounting rod. When the mounting rod stops rotating, the elastic force of the fixing spring and the magnetic force of the positioning magnet cause the fixing block to move to the fixing groove.
[0018] By adopting the above technical solution and setting positioning magnets, the situation where the fixing block remains in the positioning groove when the mounting rod stops rotating due to its own weight or unexpected situations is reduced, thereby improving the overall stability.
[0019] Optionally, the sliding sleeve is provided with a guide surface that tapers away from the mounting bracket and is used to abut against the spindle.
[0020] By adopting the above technical solution and setting a guide surface, the sliding groove can be moved towards the mounting frame simply by contacting the guide surface during the installation of the spindle, thereby facilitating the installation of the spindle and the replacement of the paper tube.
[0021] Secondly, this application provides a processing method for an automatic paper tube rewinding machine that facilitates paper tube replacement, using the following technical solution;
[0022] A processing method for an automatic paper tube rewinding machine that facilitates paper tube replacement includes the aforementioned automatic paper tube rewinding machine, and further includes the following steps:
[0023] S1: Place the yarn bobbin to be unwound on the ground, and let the yarn pass through the yarn guide assembly and be wound around the paper tube fixed on the spindle.
[0024] S2: Push the sliding sleeve toward the mounting bracket and make the spindle insert into the sliding hole;
[0025] S3: The external drive unit drives the mounting rod to rotate and drives the spindle to rotate, so that the yarn is wound around the paper tube;
[0026] S4: When paper tube replacement is required, turn off the drive to stop the mounting rod from rotating, move the sliding sleeve towards the mounting bracket and pull out the paper tube, and repeat the operation of S1 for the newly replaced paper tube.
[0027] By adopting the above technical solution, the installation and fixing of the spindle is more convenient after the paper tube is installed on the spindle, thereby improving the efficiency of the paper tube replacement operation.
[0028] In summary, this application includes at least one of the following beneficial technical effects:
[0029] 1. A sliding sleeve and a sliding spring are set up so that when the paper tube needs to be replaced, the paper tube is pre-fixed to the spindle. When the spindle is installed, the sliding sleeve is moved to provide space, so that the spindle can be inserted into the sliding hole. This facilitates the connection of the spindle with the snap-fit parts, and makes it easier to rotate the spindle indirectly when the rod is installed. This makes the replacement of the paper tube more convenient.
[0030] 2. Set a pre-clamping area so that the spindle stops in the pre-clamping area. At this time, the sliding spring is in a compressed state. When the driving component drives the mounting rod to rotate the sliding sleeve, the clamping groove corresponds to the clamping protrusion. At this time, the elastic force of the sliding spring causes the sliding sleeve to move, and the clamping protrusion is embedded in the clamping groove, thereby driving the spindle to rotate.
[0031] 3. By setting a positioning magnet, the fixed block is reduced from remaining in the positioning groove when the mounting rod stops rotating due to its own weight or unexpected situations, thereby improving the overall stability. Attached Figure Description

[0037] The present application will be further described in detail below with reference to the accompanying drawings.
[0038] This application discloses an automatic paper roll rewinding machine that facilitates paper roll replacement. (Refer to...) Figures 1 to 4The machine includes a body 1, which is provided with a yarn guide assembly 2 and a mounting frame 3. The yarn guide assembly 2 is used to guide the yarn to move towards the mounting frame 3. In this application, the yarn guide assembly 2 includes a guide wire section, a guide wire plate, and a guide wire wheel. The guide wire plate is located on the side of the guide wire section near the winding drum mounting frame 3. The guide wire wheel rotates on the guide wire plate, and the yarn moves towards the mounting frame 3 after passing through the guide wire wheel.
[0039] The machine body 1 has a groove 4, and a mounting bracket 3 is disposed above the groove 4. The mounting bracket 3 has a rotating rod 5, which is driven by a driving component. In this application, the driving component is a motor.
[0040] The rotating rod 5 includes a spindle rod 51 and a mounting rod 52. The mounting rod 52 rotates on the mounting frame 3, and the spindle rod 51 is used to fix the paper tube. The mounting frame 3 is provided with a sliding spring 6, and the mounting rod 52 is provided with a sliding sleeve 7. The end of the sliding spring 6 away from the mounting frame 3 is used to abut against the sliding sleeve 7. The sliding sleeve 7 slides on the mounting rod 52, and the sliding direction of the sliding sleeve 7 is along the axis of the mounting rod 52. The elastic force of the sliding spring 6 is used to limit the movement of the sliding sleeve 7 towards the mounting frame 3. In this application, the sliding sleeve 7 can only slide along the axis of the mounting rod 52, and the rotation of the mounting rod 52 will drive the sliding sleeve 7 to rotate.
[0041] The mounting rod 52 has a fixing groove 8 on its periphery. A fixing spring 9 is provided at the bottom of the fixing groove 8. A fixing block 10 is provided at the end of the fixing spring 9 away from the bottom of the fixing groove 8. The fixing block 10 is located in the fixing groove 8 and slides in the fixing groove 8. The sliding direction of the fixing block 10 is towards or away from the bottom of the fixing groove 8. The elastic force of the fixing spring 9 restricts the fixing block 10 from moving away from the bottom of the fixing groove 8.
[0042] The sliding hole 14 has a positioning groove 11 on its wall, into which the fixing block 10 is inserted. A positioning magnet 12 is located at the bottom of the positioning groove 11. In this application, the fixing block 10 is a fixing magnet, and the magnetic force of the fixing magnet repels the magnetic force of the positioning magnet 12. When the mounting rod 52 rotates, the fixing block 10 is thrown to the positioning groove 11 due to the rotation of the mounting rod 52. At this time, the fixing block 10 restricts the sliding sleeve 7 from moving along the axis of the mounting rod 52. When the mounting rod 52 stops rotating, the elastic force of the fixing spring 9 and the magnetic force of the positioning magnet 12 cause the fixing block 10 to move to the fixing groove 8.
[0043] In actual use, multiple fixing slots 8 and positioning slots 11 can be set, with the same number of both and their positions corresponding one-to-one.
[0044] The sliding sleeve 7 has a guide surface 13, which tapers away from the mounting bracket 3 and serves to abut against the spindle rod 51. The sliding sleeve 7 has a sliding hole 14 that passes through it, allowing the sleeve 7 to slide against the mounting rod 52. The sliding hole 14 allows the spindle rod 51 to be inserted. The wall of the sliding hole 14 has a pre-clamping area 15 located on the side of the sliding sleeve 7 away from the mounting bracket 3. The wall of the sliding hole 14 has a locking element that, when the spindle rod 51 is inserted into the sliding hole 14, causes the sliding sleeve 7 to rotate, thus rotating the spindle rod 51.
[0045] In this application, the snap-fit component includes a snap-fit protrusion 16, the extension direction of which is parallel to the axial direction of the mounting rod 52, and the snap-fit protrusion 16 extends to the pre-snap area 15 near the mounting bracket 3. The outer wall of the spindle 51 is provided with a snap-fit groove 17 for the snap-fit protrusion 16 to be inserted.
[0046] The implementation principle of an automatic paper tube rewinding machine according to an embodiment of this application is as follows: In actual use, the paper tube is fixed to the spindle 51, and then the spindle 51 is moved to contact the guide surface 13. At this time, the sliding sleeve 7 is subjected to a horizontal force and moves towards the mounting frame 3. Then the spindle 51 is inserted into the sliding hole 14. If the engaging protrusion 16 is misaligned with the engaging groove 17 at this time, the sliding spring 6 is in a compressed state, and the spindle 51 is located in the pre-engaging area 15. When the driving component drives the mounting rod 52 to rotate until the engaging protrusion 16 is aligned with the engaging groove 17, the sliding spring 6 causes the sliding sleeve 7 to move. At this time, the rotation of the sliding sleeve 7 drives the spindle 51 to rotate.
[0047] This application also discloses a processing method for an automatic paper tube rewinding machine that facilitates paper tube replacement, including the aforementioned automatic paper tube rewinding machine, and further comprising the following steps:
[0048] S1: Place the yarn bobbin to be unwound on the ground, and let the yarn pass through the yarn guide assembly 2 and wind through the grooved tube 4 onto the paper tube fixed on the spindle 51.
[0049] S2: Push the sliding sleeve 7 toward the mounting bracket 3 and make the spindle 51 engage the sliding hole 14;
[0050] S3: The external drive unit drives the mounting rod 52 to rotate and drives the spindle rod 51 to rotate, so that the yarn is wound around the paper tube;
[0051] S4: When paper tube replacement is required, turn off the drive to stop the installation rod 52 from rotating, move the sliding sleeve 7 towards the mounting bracket 3 and pull out the paper tube, and repeat the operation of S1 for the newly replaced paper tube.
[0052] The implementation principle of the processing method of the automatic paper tube rewinding machine that facilitates paper tube replacement in this application embodiment is as follows: by using this replacement method, the time spent in the step of replacing the paper tube and restarting the paper tube rewinding machine is reduced, thereby improving processing efficiency.
