Description

Technical Field

[0001] The present application relates to the technical field of twisting machines, and in particular to a twisting overtaking and step-up mechanism for twisting machines. Background Art

[0002] Twisting or direct twisting or double twisting is a mechanical refining method for yarns to produce certain usage characteristics in twisting. In the twisting method, two or more yarns are combined into one twisted yarn by rotation. The number of twisting machines is large, the required unit is also large, the transportation and assembly cycle of the parts is long, and the efficiency is low;

[0003] A review of announcement number CN211813195U reveals an active twisting machine lifting mechanism. This technology discloses "an endless belt guided by a plurality of guide wheels, one side of the endless belt connected to a linear drive device to drive the endless belt to reciprocate along the guide wheels, a lifting seat fixed to one vertical side of the endless belt, and a counterweight fixed to the other side opposite to the lifting seat and in the opposite direction of movement. The counterweight is used to balance the weight of the lifting seat and components connected to the lifting seat. This technology has the advantages of actively driving the lifting movement of components by reciprocatingly driving the endless belt, ensuring stable and reliable execution of the lifting action."

[0004] With regard to the above-mentioned related technologies, the inventor believes that the ratchet in the existing thread twisting overrunning step-up mechanism is too large, which makes it easy for the thread twisting overrunning step-up mechanism to cause the thread to fall out of the loop. At the same time, the thread twisting overrunning step-up mechanism does not have a mechanism to limit the position of the ratchet during rotation, which is not conducive to the use of the thread twisting overrunning step-up mechanism and does not have the effect of preventing the thread from falling out of the loop and preventing the thread from falling out. Secondly, the existing thread twisting overrunning step-up mechanism does not have a structure to push the pawl to rotate. When the ratchet needs to be reversed, the pawl needs to be disengaged from the ratchet. There is no pushing mechanism, which makes it inconvenient to automatically push the pawl out of the ratchet, reducing the convenience of using the thread twisting overrunning step-up mechanism.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0031] Example 1

[0032] A twisting overrunning step-up mechanism for a twisting machine includes a chassis plate 1, one end of which is rotatably connected to a ratchet 5, an upper portion of one end of the chassis plate 1 is fixedly connected to a long rod 7, the long rod 7 serves as a connection, and one end of the long rod 7 is rotatably connected to a round rod 6, the round rod 6 serves as a connection.

[0033] The outer surface of the round rod 6 is fixedly sleeved with a pawl 4 used in conjunction with the ratchet 5. The pawl 4 is used in conjunction with the ratchet 5 to limit the rotation of the ratchet 5. The bottom end of the pawl 4 contacts the outer surface of the ratchet 5, making it easier for the pawl 4 to cooperate with the ratchet 5.

[0034] One end of the ratchet 5 and one end of the chassis plate 1 are jointly provided with a limiting mechanism 2 used in conjunction with the ratchet 5. The limiting mechanism 2 plays a limiting role. The limiting mechanism 2 includes a connecting rod 21. One end of the connecting rod 21 is fixedly connected to the middle part of one end of the ratchet 5. The connecting rod 21 plays a connecting role.

[0035] A connecting plate 22 is fixedly sleeved on the outer surface of the connecting rod 21 . The connecting plate 22 serves as a connection, and one end of the connecting plate 22 is fixedly connected to the limit frame 28 .

[0036] A first mounting hole 27 is provided at one end of the chassis plate 1, a positioning rod 24 is movably provided at one end of the chassis plate 1, and a second mounting hole 26 is provided at one end of the positioning rod 24 for use with the first mounting hole 27. The inner walls of the first mounting hole 27 and the second mounting hole 26 are commonly threadedly connected with a bolt 25, and the first mounting hole 27 and the second mounting hole 26 are used together with the bolt 25 to install the positioning rod 24.

[0037] The inner walls of the first mounting hole 27 and the second mounting hole 26 are both threaded, and the inner wall threads of the first mounting hole 27 and the second mounting hole 26 match the outer surface threads of the bolt 25, so that the bolt 25 can be used in conjunction with the first mounting hole 27 and the second mounting hole 26 to firmly mount the positioning rod 24 on the chassis plate 1.

[0038] The inner wall of the positioning rod 24 is fixedly connected with a limiting rod 23 used in conjunction with the limiting frame 28. The outer surface of the limiting rod 23 is in sliding contact with the inner walls on both sides of the limiting frame 28. The limiting frame 28 cooperates with the limiting rod 23 to limit the rotation position of the ratchet 5.

[0039] The limit frame 28 is arc-shaped, and the limit frame 28 and the ratchet 5 are concentrically arranged, which makes it easier for the limit frame 28 to cooperate with the limit rod 23 to achieve the limiting effect, thereby making the twisting and exceeding the level-lifting mechanism have the effect of preventing the loop from falling off and the teeth from being reversed.

[0040] A pushing mechanism 3 is provided inside the long rod 7 for use with the pawl 4. The pushing mechanism 3 plays a pushing role. The pushing mechanism 3 includes a first groove 34. The first groove 34 is opened at the bottom end of the long rod 7. The inner walls on both sides of the first groove 34 are fixedly connected with a support seat 33. The first groove 34 serves to facilitate the installation of the support seat 33.

[0041] The top end of the support base 33 is fixedly connected to a motor 35 . The support base 33 supports the motor 35 , and the motor 35 drives the pushing mechanism 3 .

[0042] The output end of the motor 35 passes through the inner wall of one side of the first groove 34 and is fixedly connected to a screw 37, so that the output end of the motor 35 can drive the screw 37 to rotate. The bottom end of the long rod 7 is provided with a second groove 38 for use with the screw 37. The end of the screw 37 away from the output end of the motor 35 is rotatably connected to the inner wall of one side of the second groove 38. The second groove 38 serves to position the screw 37 during rotation.

[0043] The outer surface of the screw rod 37 is threadedly sleeved with the connecting block 31 , and the inner wall thread of the connecting block 31 matches the outer surface thread of the screw rod 37 , so that the screw rod 37 rotates to drive the connecting block 31 to move.

[0044] The two ends of the connecting block 31 are respectively slidably connected to the inner walls of the two sides of the second groove 38, so that the second groove 38 can guide and limit the connecting block 31 when it moves, and the bottom end of the connecting block 31 is fixedly connected to the vertical rod 36, so that the movement of the connecting block 31 can drive the vertical rod 36 to move.

[0045] The lower part of one end of the vertical rod 36 is fixedly connected to the push rod 32 used in conjunction with the pawl 4. The vertical rod 36 plays a connecting role, so that the movement of the vertical rod 36 drives the push rod 32 to move, and the movement of the push rod 32 drives the pawl 4 to rotate around the center of the round rod 6.

[0046] The pushing rod 32 is cylindrical, and the end of the pushing rod 32 facing away from the vertical rod 36 is flush with the surface of one end of the pawl 4, so that the pushing rod 32 can better push the pawl 4 to rotate, so that the pawl 4 disengages from the ratchet 5, so as to facilitate the reversal of the ratchet 5 and improve the convenience of using the twisting and overtaking step-up mechanism.

[0047] Working principle: First, through the limiting mechanism 2, the first mounting hole 27 and the second mounting hole 26 cooperate with the bolt 25 to install the positioning rod 24 at a suitable position on the chassis plate 1.

[0048] Then, the limiting rod 23 on the positioning rod 24 cooperates with the connecting rod 21 and the connecting plate 22 to form a limiting frame 28 to limit the rotation of the ratchet 5.

[0049] The ratchet wheel 5 is limited when rotating, so that the twisting yarn exceeds the step-up mechanism, which can make the bobbin well formed, reduce the loop undoing and prevent the back teeth.

[0050] At the same time, by reducing the size of the ratchet wheel 5, the anti-slip effect is improved.

[0051] When the pawl 4 needs to be disengaged from the ratchet wheel 5, the motor 35 is started by pushing the mechanism 3. The output end of the motor 35 drives the screw 37 to rotate. The second groove 38 plays a role in positioning the screw 37 during rotation.

[0052] The screw rod 37 rotates to drive the connecting block 31 to move. The second groove 38 guides and limits the connecting block 31 when it moves. The movement of the connecting block 31 drives the vertical rod 36 to move.

[0053] The movement of the vertical rod 36 drives the push rod 32 to move, and the movement of the push rod 32 drives the pawl 4 to rotate around the center of the round rod 6, so that the pawl 4 disengages from the ratchet 5 and cancels the limit on the ratchet 5, making it convenient for the ratchet 5 to reverse.

Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
