Technical Field
[0001] The utility model relates to a yarn bobbin fixing mechanism for a twisting machine, belonging to the technical field of twisting machines. Background Art
[0002] A yarn bobbin is usually arranged in a twisting machine. The yarn bobbin includes a hollow cylinder body and a yarn wound around the cylinder body. In the prior art, the fixing device of the yarn bobbin usually includes a base fixed on the twisting machine. A rotating shaft is rotatably connected to the base, and the yarn bobbin is arranged on the rotating shaft. The yarn bobbin supplies yarn to the twisting machine by rotating.
[0003] However, in the actual use process of the twisting machine, due to the fixed size of the existing fixing device and the different heights of the yarn bobbins, if an unsuitable fixing device is used to fix the yarn bobbin, the yarn bobbin is very likely to come off due to the centrifugal force during rotation, and the use is very unstable, resulting in uneven twist of the yarn and breakage of the yarn, greatly reducing the production efficiency of the yarn. Summary of the Utility Model
[0004] The technical problem to be solved by the utility model is as follows: to provide a yarn bobbin fixing mechanism for a twisting machine, which solves the problem that in the prior art, due to the different specifications of the yarn bobbins and different heights, the fixing device is not matched with the height of the yarn bobbin, resulting in unstable fixing of the yarn bobbin and shaking, thus making the yarn supply of the twisting machine unstable, and further leading to uneven twist of the yarn and breakage of the yarn, increasing the equipment failure and downtime, and greatly reducing the quality and production efficiency of the yarn.
[0005] The technical problem to be solved by the utility model is achieved by adopting the following technical solutions: a yarn bobbin fixing mechanism for a twisting machine includes a base. A rotating shaft is rotatably connected to one side of the base, and a yarn bobbin is sleeved on the rotating shaft. A measuring rod is fixed to the other side of the base. An adjusting plate is slidably connected vertically between the measuring rod and the rotating shaft. A through hole one is opened at one end of the adjusting plate close to the measuring rod, and a through hole two is opened at one end of the adjusting plate close to the rotating shaft. The adjusting plate is connected to the measuring rod through a reinforcement structure. The reinforcement structure includes a circular groove opened on the adjusting plate. A clamping block is slidably connected in the circular groove, and a plurality of clamping grooves for the clamping block to be inserted into are opened on the measuring rod.
[0006] By adopting the above technical solution, during the actual process of using the fixing mechanism to fix the yarn bobbin, the staff first fix the base on the twisting machine, then set the yarn bobbin on the rotating shaft, and then use the reinforcement structure to make the clamping block disengage from the circular groove. Then, move the adjusting plate to align the measuring rod with the first through hole and the rotating shaft with the second through hole. Then, slide the adjusting plate downward along the vertical directions of the measuring rod and the rotating shaft, and respectively snap the tops of the measuring rod and the rotating shaft into the first through hole and the second through hole. As the adjusting plate continues to move downward, the adjusting plate slides to the height of the yarn bobbin, and at the same time, the bottom of the end close to the rotating shaft abuts against the top of the yarn bobbin. Finally, the staff use the reinforcement structure to snap the clamping block along the circular groove into the clamping groove flush with the height of the yarn bobbin, and the adjusting plate can be fixed on the measuring rod. By using the fixing mechanism of the present application to fix the yarn bobbin, the fixing mechanism is adapted to the size of the yarn bobbin and stably fixes the yarn bobbin on the fixing device, so that the yarn bobbin is not easily disengaged due to the centrifugal force during the rotation process, the use is very stable and the yarn twist is uniform, greatly improving the production efficiency of the yarn.
[0007] The present utility model is further arranged such that: a plurality of clamping grooves are uniformly opened along the length direction of the measuring rod.
[0008] By adopting the above technical solution, the uniformly opened clamping grooves correspond to yarn bobbins of different height types. After the staff move the adjusting plate to the height of the yarn bobbin, the clamping block can be more quickly and accurately inserted into the clamping groove along the circular groove, and it will not be impossible or difficult to insert the clamping block into the clamping groove due to the position of the clamping groove, which is very convenient and efficient.
[0009] The present utility model is further arranged such that: a driving member for driving the clamping block to rotate and snap into the clamping groove is further fixed on the adjusting plate. The driving member includes a hinge seat, a rotating rod is rotatably connected in the hinge seat, the clamping block is fixed on the rotating rod, and one side of the rotating rod close to the rotating shaft is connected to the adjusting plate through an elastic member. In this embodiment, the elastic member is a compression spring.
[0010] By adopting the above technical solution, when the clamping block needs to be disengaged from the circular groove, the staff press one end of the rotating rod close to the rotating shaft, so that the compression spring is compressed and generates elastic force. At the same time, the rotating rod rotates in the hinge seat, and the rotation of the rotating rod drives the clamping block to rotate, so that the clamping block disengages from the circular groove.
[0011] When the clamping block needs to be snapped into the clamping groove, the staff only need to remove the pressure on the rotating rod, so that the compression spring expands and releases elastic force, causing the rotating rod to rotate in the hinge seat. The rotation of the rotating rod drives the clamping block to rotate, so that the clamping block is snapped into the clamping groove along the circular groove. Through the limitation of the clamping block by the clamping groove, the measuring rod limits the adjusting plate in the vertical direction, so that the adjusting plate cannot slide vertically on the rotating shaft and the measuring rod, and the connection between the adjusting rod and the measuring rod can be completed. The operation is simple and very convenient.
[0012] The present utility model is further configured such that: the opening of the circular groove is larger than the opening of the clamping groove.
[0013] By adopting the above technical solution, with the circular groove being larger than the clamping groove, when the rotating rod rotates to drive the clamping block to rotate, since the rotation trajectory is arc-shaped, when the clamping block rotates out of the clamping groove and rotates into the circular groove, the clamping block will not be restricted by the opening size of the circular groove from disengaging from the clamping groove and rotating into the circular groove, and the arc-shaped setting of the inner wall of the clamping groove enables the clamping block to smoothly rotate out of the clamping groove.
[0014] The present utility model is further configured such that: fixing holes are provided on the base, bearings are fixed in the fixing holes, the end of the rotating shaft is connected to the bearings, and one end of the rotating shaft close to the base penetrates through the base and is connected with a motor.
[0015] By adopting the above technical solution, when it is necessary to rotate the yarn bobbin, the staff only needs to start the motor to make the rotating shaft rotate, and the rotation of the rotating shaft drives the yarn bobbin to rotate, and the rotation of the yarn bobbin can complete the outgoing line of the yarn bobbin for the twisting machine, which is very convenient.
[0016] The beneficial effect of the present utility model is that: in the actual process of using the fixing mechanism to fix the yarn bobbin, the staff first fixes the base on the twisting machine, then sets the yarn bobbin on the rotating shaft, and then uses the reinforcement structure to make the clamping block disengage from the circular groove. Then, move the adjusting plate to align the measuring rod with the first through hole and the rotating shaft with the second through hole, and then slide the adjusting plate downward along the vertical directions of the measuring rod and the rotating shaft, and respectively clamp the tops of the measuring rod and the rotating shaft into the first through hole and the second through hole. As the adjusting plate continues to move downward, the adjusting plate slides to the height of the yarn bobbin, and at the same time, the bottom of the end close to the rotating shaft abuts against the top of the yarn bobbin. Finally, the staff uses the reinforcement structure to clamp the clamping block into the clamping groove flush with the height of the yarn bobbin along the circular groove, and the adjusting plate can be fixed on the measuring rod. By using the fixing mechanism of the present application to fix the yarn bobbin, the fixing mechanism is adapted to the size of the yarn bobbin and stably fixes the yarn bobbin on the fixing device, so that the yarn bobbin is not easily disengaged due to the centrifugal force during the rotation process, the use is very stable and the yarn twist is uniform, greatly improving the production efficiency of the yarn.

DETAILED DESCRIPTION
[0022] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific illustrations.
[0023] like Figure 1 and Figure 2 As shown, a yarn bobbin fixing mechanism for a twisting machine comprises a base 1, one side of the base 1 is rotatably connected to a rotating shaft 2, a yarn bobbin 3 is sleeved on the rotating shaft 2, a measuring rod 4 is fixed to the other side of the base 1, an adjusting plate 5 is vertically slidably connected between the measuring rod 4 and the rotating shaft 2, a through hole 1 6 is provided at one end of the adjusting plate 5 close to the measuring rod 4, a through hole 2 7 is provided at one end of the adjusting plate 5 close to the rotating shaft 2, the adjusting plate 5 is connected to the measuring rod 4 through a reinforcement structure, the reinforcement structure comprises a circular groove 13 provided on the adjusting plate 5, a clamping block 10 is slidably connected in the circular groove 13, and a plurality of clamping grooves 12 for clamping the clamping block 10 are provided on the measuring rod 4.
[0024] In the process of actually using the fixing mechanism to fix the bobbin 3, the staff first fixes the base 1 on the twisting machine, and then sets the bobbin 3 on the rotating shaft 2. Then, the staff uses the reinforcement structure to disengage the block 10 from the circular groove 13, and then moves the adjustment plate 5 to align the measuring rod 4 with the through hole 1 6 and the rotating shaft 2 with the through hole 2 7. Then, the adjustment plate 5 slides downward along the vertical direction of the measuring rod 4 and the rotating shaft 2, and the tops of the measuring rod 4 and the rotating shaft 2 are respectively inserted into the through hole 1 6 and the through hole 2 7. As the adjustment plate 5 continues to move downward, the adjustment plate 5 slides to the height of the bobbin 3. , and at the same time, the bottom of one end close to the rotating shaft 2 is in contact with the top of the yarn tube 3. Finally, the staff uses the reinforcement structure to insert the block 10 into the slot 12 flush with the height of the yarn tube 3 along the circular groove 13, and the adjustment plate 5 can be fixed on the measuring rod 4. The yarn tube 3 is fixed by using the fixing mechanism of the present application, so that the fixing mechanism is adapted to the size of the yarn tube 3 and the yarn tube 3 is stably fixed on the fixing device, so that the yarn tube 3 is not easy to fall out due to the centrifugal force during the rotation process. It is very stable to use and the yarn twist is uniform, which greatly improves the yarn production efficiency.
[0025] like Figure 1 As shown, a plurality of slots 12 are evenly arranged along the length direction of the measuring rod 4 .
[0026] The evenly arranged card slots 12 correspond to yarn cones 3 of different height types. After the staff moves the adjusting plate 5 to the height of the yarn cone 3, the clamping block 10 can be inserted into the card slot 12 along the circular groove 13 more quickly and accurately, and it will not be impossible or difficult to insert the clamping block 10 into the card slot 12 due to the position of the card slot 12, which is very convenient and efficient.
[0027] As Figure 2 and Figure 4 shown, a driving member for driving the clamping block 10 to rotate and engage with the card slot 12 is also fixed on the adjusting plate 5. The driving member includes a hinge seat 9, a rotating rod 8 is rotatably connected in the hinge seat 9, the clamping block 10 is fixed on the rotating rod 8, and one side of the rotating rod 8 close to the rotating shaft 2 is connected to the adjusting plate 5 through an elastic member. In this embodiment, the elastic member is a compression spring 11.
[0028] Among them, the opening of the circular groove 13 is larger than the opening of the card slot 12.
[0029] When the clamping block 10 is to be disengaged from the circular groove 13, the staff presses one end of the rotating rod 8 close to the rotating shaft 2, so that the compression spring 11 is compressed and generates an elastic force. At the same time, the rotating rod 8 rotates in the hinge seat 9, and the rotation of the rotating rod 8 drives the clamping block 10 to rotate, so that the clamping block 10 disengages from the circular groove 13.
[0030] When the clamping block 10 is to be inserted into the card slot 12, the staff only needs to remove the pressure on the rotating rod 8, so that the compression spring 11 expands and releases the elastic force to make the rotating rod 8 rotate in the hinge seat 9. The rotation of the rotating rod 8 drives the clamping block 10 to rotate, so that the clamping block 10 is inserted into the card slot 12 along the circular groove 13. Through the limitation of the clamping block 10 by the card slot 12, the measuring rod 4 limits the adjusting plate 5 in the vertical direction, so that the adjusting plate 5 cannot slide vertically on the rotating shaft 2 and the measuring rod 4, and the connection between the adjusting rod and the measuring rod 4 can be completed. The operation is simple and very convenient.
[0031] Among them, the setting that the circular groove 13 is larger than the card slot 12 is such that when the rotating rod 8 rotates to drive the clamping block 10 to rotate, since the rotation trajectory is arc-shaped, when the clamping block 10 rotates out of the card slot 12 and rotates to the circular groove 13, the disengagement of the clamping block 10 from the card slot 12 and the rotation out of the circular groove 13 will not be restricted by the opening size of the circular groove 13. The arc-shaped setting of the inner wall of the card slot 12 enables the clamping block 10 to smoothly rotate out of the card slot 12.
[0032] As Figure 3 shown, a fixing hole 14 is opened on the base 1, a bearing 15 is fixed in the fixing hole 14, the end of the rotating shaft 2 is connected to the bearing 15, and one end of the rotating shaft 2 close to the base 1 penetrates through the base 1 and is connected to a motor 16.
[0033] When it is necessary to rotate the yarn bobbin 3, the staff only needs to start the motor 16 to make the rotating shaft 2 rotate. The rotation of the rotating shaft 2 drives the yarn bobbin 3 to rotate, and the rotation of the yarn bobbin 3 can complete the outgoing line of the yarn bobbin 3 to the twisting machine, which is very convenient.
[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present invention. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
