Description

Technical Field

[0001] The present application relates to the field of textile technology, and in particular to an oversized diameter adjustment device for the front stop of a spinning frame. Background Art

[0002] The spinning frame is a spinning machine that draws, twists and winds semi-finished roving or slivers into spun yarn tubes during the textile process. The roving is fed into the drafting mechanism for drafting operation.

[0003] In this process, refer to the instructions attached Figure 1 , an upper apron Ⅰ6' and a lower apron Ⅰ5' are set between the front and middle rollers to control the fibers in the drafting zone (the contact part between the upper and lower aprons). The aprons use flexible elements to 'control' the fibers in the drafting zone and transport them forward at the linear speed of the rear roller until they are close to the jaws of the front roller (the teeth formed by the upper pin Ⅰ2' and the lower pin Ⅰ1'), allowing the fiber head to enter the jaws of the front roller ( Figure 1 ), the ideal situation is that the flexible element should have a uniform vertical pressure on the fiber, and can have a good control effect on all fibers. Therefore, the upper and lower aprons should be in "close" contact, which is the basic requirement of the apron mechanism. However, the two aprons are driven by the friction of the middle roller Ⅰ3'. The pressure between the middle roller Ⅰ3' and the upper pressure roller Ⅰ4' clamps the two layers of aprons and transports them forward (the force on the aprons is forward). In the front, there is also pressure between the upper and lower pins, and there is friction resistance (the force on the aprons is backward). These two forces force the middle flexible apron to relax or even "arch" ( Figure 2 ), if no measures are taken, the pressure generated by the working surface will be uneven and unstable, and it will be impossible to generate uniform pressure on the fibers to effectively control the fibers. Summary of the invention

[0004] The present application proposes an extra-large diameter adjustment device for the front leather position of a spinning machine, which has the advantages of increasing friction resistance to eliminate slight arching, providing power to the arched part to energize the electromagnet to obtain repulsive force, pushing the adjusting roller to move and tension the leather ring under the repulsive force to eliminate the arching, increasing the friction force of the adjusting roller when tensioning the leather ring to transfer the arching to the top of the leather ring, and slowly resetting the adjusting roller to remove the long-term excessive tension of the leather ring, so as to solve the problem of arching of the existing leather ring mechanism.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a super-large diameter adjustment device for the front gear leather position of a spinning machine, comprising a frame, a lower roller, a middle roller, an upper pressure roller, a lower pin and an upper pin, wherein the lower pin is located above the lower roller, the upper pin is located above the lower pin, the middle roller is located on one side of the lower pin, and the upper pressure roller is located above the middle roller; a storage seat is respectively arranged between the upper pin and the upper pressure roller and between the lower pin and the middle roller, wherein two symmetrical movable cavities are arranged in the storage seat, a long rod is arranged in the movable cavity, one end of the long rod movably passes through a center rod arranged on the storage seat, a resistance inner sleeve is arranged on the outer side of the center rod, which is used to change the friction resistance between the center rod and the center rod under different force states, and an adjusting roller is arranged on the outer side of the resistance inner sleeve; an upper leather ring is sleeved on the upper pin, the upper pressure roller and the upper adjusting roller, and a lower leather ring is sleeved on the lower pin, the lower roller, the middle roller and the lower adjusting roller.

[0006] Preferably, two ends of the lower roller, the middle roller and the upper pressure roller are movably arranged on two sides of the frame, and two ends of the lower pin and the upper pin are fixed on two sides of the frame.

[0007] Preferably, a repulsion magnet is provided at one end of the long rod close to the upper pin, and a return spring wound around the outside of the long rod is provided between the repulsion magnet and the end of the movable cavity away from the upper pin, for adjusting the force on the position of the adjusting roller.

[0008] Preferably, evenly distributed lifting ropes are provided at the bottom end of the storage seat at the top, and the bottom ends of the lifting ropes are connected to a force-bearing plate, which is located above the inner side below the upper leather ring and is used to receive the upward force of the upper leather ring.

[0009] Preferably, a current seat is fixedly connected to the center of the bottom end of the storage seat at the top, a closed groove is opened at the bottom end of the current seat, symmetrical electric patches are fixedly connected on both sides of the bottom of the closed groove, and connecting wires are arranged in the current seat for transmitting current.

[0010] Preferably, the top of the force-bearing plate is fixedly connected to a transmission plate, and the top of the transmission plate is fixedly connected to a connecting electric sheet, which is used to move synchronously with the force-bearing plate. The top of the transmission plate is inserted into a closed groove, and the thickness of the connecting electric sheet is equal to the spacing between the two electric patches, which is used to connect or disconnect the current.

[0011] Preferably, an electromagnet is provided at one end of the movable cavity away from the repulsive magnet, the electromagnet and the repulsive magnet repel each other, the electromagnet and the electric patch are electrically connected through connecting wires, and the electric patch is electrically connected to the existing circuit to drive the adjustment roller to move linearly.

[0012] The present application provides an oversized diameter adjustment device for the front leather position of a spinning machine. When the leather ring is started, it will apply a force to the adjusting roller in the direction of the jaws, and the adjusting roller has friction resistance to the leather ring. When the leather ring has a slight "arching" phenomenon at the contact position between the upper leather ring and the lower leather ring due to force problems, the pulling force of the leather ring on the adjusting roller in the direction of the jaws will increase, so that the contact force between the resistance inner sleeve on the inner side of the adjusting roller and the center rod is strengthened, resulting in increased friction, thereby increasing the friction between the adjusting roller and the leather ring. The friction resistance here is in the opposite direction to the friction resistance to the leather ring at the jaws, thereby pulling the leather ring to eliminate the slight "arching".

[0013] At the same time, when the leather ring shows severe "arching" phenomenon at the contact position of the upper leather ring and the lower leather ring due to force problems, the arched part of the upper leather ring will push up the force plate, driving the transmission plate to connect the connecting electric plate with the electric patch, so that the electromagnet is energized to obtain magnetic force, and repels the repulsive magnet, so that the long rod drives the center rod to push the adjusting roller to move away from the storage seat, and the leather ring is pulled by the moving adjusting roller to adjust the tension of the leather ring, so that the "arched" leather ring is flattened under the pulling.

[0014] At the same time, when the adjustment is completed, the force-bearing plate will lose the upward thrust of the leather ring below, so that the force-bearing plate will drive the transmission plate under its own weight to pull the connecting electrical sheet downward and reset, disconnect the electrical patch and the connecting electrical sheet, and make the electromagnet power off and gradually lose repulsive force. Driven by the reset spring, the adjusting roller slowly moves toward the direction of the storage seat and resets, so that the leather ring gradually recovers and reduces the tension, avoiding the adjusting roller from adjusting the tension of the leather ring too tightly for a long time, which will cause negative effects such as rapid deformation of the leather ring, reduced life and slipping.

[0015] At the same time, when the adjusting roller moves to adjust the tension of the strongly "arched" leather ring, the force exerted by the leather ring on the adjusting roller in the direction of the jaws increases, and the contact force between the resistance inner sleeve on the inner side of the adjusting roller and the center rod is strengthened. The force exerted by the center rod on the resistance inner sleeve is opposite to the direction of the force exerted by the leather ring on the adjusting roller, which further strengthens the contact force between the resistance inner sleeve and the center rod and increases the friction force, thereby further increasing the friction force between the adjusting roller and the leather ring. The friction resistance here is opposite to the direction of the friction resistance to the leather ring at the jaws, thereby pulling the leather ring and quickly eliminating the strongly "arched" part of the leather ring.

[0016] At the same time, as the friction between the adjusting roller and the leather ring increases rapidly, the self-rotation ability of the adjusting roller weakens. Taking the clockwise rotation of the upper leather ring as an example, at this time, the adjusting roller has a high-intensity friction resistance to the clockwise rotating upper leather ring in the relative direction, and the upper pressure roller provides clockwise traction to the upper leather ring, which is opposite to the friction resistance provided by the adjusting roller, resulting in "arching" of the upper leather ring between the upper pressure roller and the adjusting roller, thereby transferring the "arching" below the upper leather ring to the top, quickly eliminating the "arching" below.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Embodiment 1

[0021] See also Figure 3 to Figure 4A super-large diameter adjustment device for the front stop of a spinning machine comprises a frame 1, a lower roller 2, a middle roller 3, an upper pressure roller 4, a lower pin 5 and an upper pin 6. The two ends of the lower roller 2, the middle roller 3 and the upper pressure roller 4 are movably sleeved on both sides of the frame 1, and the two ends of the lower pin 5 and the upper pin 6 are respectively fixed on both sides of the frame 1 by bolts, and the positions of the lower roller 2, the middle roller 3, the upper pressure roller 4, the lower pin 5 and the upper pin 6 are fixed by the frame 1.

[0022] See also Figure 3 , Figures 5 and 6 The lower pin 5 is located above the lower roller 2, the upper pin 6 is located above the lower pin 5, the middle roller 3 is located on one side of the lower pin 5, and the upper pressure roller 4 is located above the middle roller 3. The lower roller 2, the middle roller 3 and the upper pressure roller 4 are controlled to rotate by an existing transmission device, such as a stepping motor and a transmission, and the staggered positions of the lower pin 5 and the upper pin 6 form a jaw.

[0023] See also Figure 3 , Figures 5 to 7 A storage seat 9 is respectively arranged between the upper pin 6 and the upper pressure roller 4 and between the lower pin 5 and the middle roller 3. The storage seat 9 is composed of two symmetrical parts fixed by bolts, so that the storage seat 9 can be disassembled, which is convenient for the installation and disassembly of the electromagnet 11 and the long rod 12. The two sides of the storage seat 9 are fixedly connected to the two sides of the frame 1 by bolts. Two symmetrical movable cavities 10 are provided in the storage seat 9. The long rod 12 is movably sleeved in the movable cavity 10. The end of the long rod 12 close to the upper pin 6 is fixedly connected to a repulsion magnet 13. The repulsion magnet 13 and the end of the movable cavity 10 away from the upper pin 6 are connected. A reset spring 14 is fixedly connected, and the reset spring 14 is movably sleeved on the outside of the long rod 12 located in the movable chamber 10, so that the long rod 12 can reciprocate in the movable chamber 10. When the upper apron 8 and the lower apron 7 are installed, the upper apron 8 and the lower apron 7 will contact different upper and lower adjustment rollers 16 respectively. The aprons (upper apron 8 and lower apron 7) exert a pulling force on the adjustment roller 16 in the direction of the storage seat 9, so that the adjustment roller 16 drives the long rod 12 to move in the direction of the storage seat 9 through the center rod 15, so that the reset spring 14 is stretched. When the aprons are started (see the attached manual), the adjustment roller 16 is pulled in the direction of the storage seat 9. Figure 6 For example, the counterclockwise rotating middle roller 3 drives the lower leather ring 7 to rotate counterclockwise toward the jaw, and the clockwise rotation of the upper pressure roller 4 drives the upper leather ring 8 to rotate clockwise toward the jaw position. At the same time, the friction between the lower leather ring 7 and the upper leather ring 8 will also drive the leather ring to rotate synchronously toward the jaw position). The loose leather ring will be tightened, and there will be a greater pulling force on the adjusting roller 16 in the direction of the storage seat 9, so that the long rod 12 moves toward the storage seat 9 to the maximum limit. At this time, the reset spring 14 stretches and limits the position of the long rod 12.

[0024] See also Figure 3 , Figures 5 to 7One end of the long rod 12 movably penetrates the end of the storage seat 9 away from the upper pin 6, and one end of the two long rods 12 protruding from the storage seat 9 is fixedly connected to the center rod 15, and the outer side of the center rod 15 is movably sleeved with a resistance inner sleeve 17, and the outer side of the resistance inner sleeve 17 is fixedly sleeved with an adjusting roller 16. The upper pin 6, the upper pressure roller 4 and the upper adjusting roller 16 are movably sleeved with an upper apron 8, and the lower pin 5, the lower roller 2, the middle roller 3 and the lower adjusting roller 16 are movably sleeved with a lower apron 7. When the apron is started, it will exert a force in the direction of the jaws on the adjusting roller 16. force, and the adjusting roller 16 has frictional resistance to the apron. When the apron has a slight "arching" phenomenon at the contact position between the upper apron 8 and the lower apron 7 due to the force problem, the pulling force of the apron on the adjusting roller 16 toward the jaws will increase, which will strengthen the contact force between the resistance inner sleeve 17 on the inner side of the adjusting roller 16 and the center rod 15, resulting in increased friction, thereby increasing the friction between the adjusting roller 16 and the apron. The frictional resistance here is in the opposite direction to the frictional resistance to the apron at the jaws, thereby pulling the apron to eliminate the slight "arching".

[0025] The material of the resistance inner sleeve 17 can be TPU, rubber or elastic plastic, etc. The two ends of the adjusting roller 16 are respectively abutted against the long rods 12 on both sides, so that the long rods 12 on both sides limit the position of the adjusting roller 16, so that the adjusting roller 16 cannot be displaced in the axial direction of the center rod. Embodiment 2

[0026] See also Figure 3 , Figures 5 to 7 On the basis of the first embodiment, the bottom end of the storage seat 9 at the top is fixedly connected with an evenly distributed lifting rope 24, and the bottom end of the lifting rope 24 is fixedly connected with a force-bearing plate 25. The force-bearing plate 25 is located above the inner side of the lower part of the upper leather ring 8, so that the force-bearing plate 25 is suspended above the inner side of the lower part of the upper leather ring 8, and will not directly contact the upper leather ring 8, avoiding contact and causing the friction force on the upper leather ring 8 to increase further at this point. Only when the upper leather ring 8 has a strong "arching" phenomenon at this point, the "arched" part of the upper leather ring 8 will push the force-bearing plate 25 upward, and the top of the force-bearing plate 25 is fixedly connected with a transmission plate 22, and the top of the transmission plate 22 is fixedly connected with a connecting electric sheet 23. When the force-bearing plate 25 is pushed up by the "arching" tail, or when the force-bearing plate 25 loses the lifting force of the "arching" part and falls under its own weight, it will drive the connecting electric sheet 23 to move synchronously through the transmission plate 22.

[0027] See also Figure 6 , Figures 8 to 9A current seat 18 is fixedly connected to the center of the bottom end of the storage seat 9 at the top, and a closed groove 19 is opened at the bottom end of the current seat 18. Symmetrical electric patches 20 are fixedly connected on both sides of the bottom of the closed groove 19. The top of the transmission plate 22 is inserted into the closed groove 19. The thickness of the connecting electric patch 23 is equal to the spacing value between the two electric patches 20, so that when the transmission plate 22 drives the connecting electric patch 23 to lift up, the connecting electric patch 23 can contact the two electric patches 20, thereby connecting the power supply. When the transmission plate 22 drives the connecting electric patch 23 to move downward, the connecting electric patch 23 can be separated from the two electric patches 20, thereby disconnecting the power supply.

[0028] See also Figures 5 to 9 An electromagnet 11 is fixedly connected to one end of the active cavity 10 away from the repulsive magnet 13, and the electromagnet 11 and the repulsive magnet 13 repel each other. A connecting wire 21 is provided in the current seat 18, and the electromagnet 11 and the electric patch 20 are electrically connected through the connecting wire 21, and the electric patch 20 is electrically connected to the existing circuit. When the leather ring has a severe "arching" phenomenon at the contact position between the upper leather ring 8 and the lower leather ring 7 due to force problems, the arched part of the upper leather ring 8 will push up the force plate 25, drive the transmission plate 22 to connect the connecting electric sheet 23 with the electric patch 20, so that the electromagnet 11 is energized to obtain magnetic force, and repel the repulsive magnet 13, so that the long rod 12 drives the center rod 15 to push the adjusting roller 16 to move in the direction away from the storage seat 9, and the leather ring is pulled by the moving adjusting roller 16 to adjust the tension of the leather ring, so that the "arched" leather ring is flattened under the pulling.

[0029] At the same time, when the adjustment is completed, the force-bearing plate 25 will lose the upward thrust of the upper leather ring 8, so that the force-bearing plate 25 drives the transmission plate 22 under its own weight to pull the connecting electric sheet 23 downward and reset, disconnecting the electric patch 20 and the connecting electric sheet 23, so that the electromagnet 11 is powered off and gradually loses its repulsive force. Driven by the reset spring 14, the adjusting roller 16 slowly moves toward the direction of the storage seat 9 and resets, so that the leather ring gradually recovers and reduces the tension, thereby avoiding the adjusting roller 16 from adjusting the tension of the leather ring too tightly for a long time, which leads to negative effects such as rapid deformation, reduced life and slipping of the leather ring.

[0030] At the same time, when the adjusting roller 16 moves to adjust the tension of the strongly "arched" leather ring, the force applied by the leather ring on the adjusting roller 16 in the direction of the jaws increases, and the contact force between the resistance inner sleeve 17 on the inner side of the adjusting roller 16 and the center rod 15 is strengthened, and the force applied by the center rod 15 to the resistance inner sleeve 17 is opposite to the direction of the force applied by the leather ring on the adjusting roller 16, so that the contact force between the resistance inner sleeve 17 and the center rod 15 is further strengthened, and the friction force is increased, thereby further increasing the friction force between the adjusting roller 16 and the leather ring. The friction resistance here is opposite to the direction of the friction resistance to the leather ring at the jaws, thereby pulling the leather ring and quickly eliminating the strongly "arched" part of the leather ring.

[0031] At the same time, during the rapid increase of the friction between the adjusting roller 16 and the apron, the self-rotation ability of the adjusting roller 16 is weakened, and the apron 8 rotates clockwise (see the instruction manual). Figure 6 ) rotation as an example, at this time, the adjusting roller 16 has a high-strength friction resistance in the relative direction to the upper leather ring 8 rotating clockwise, and the upper pressure roller 4 provides a clockwise traction force to the upper leather ring 8, which is opposite to the friction resistance provided by the adjusting roller 16, resulting in "arching" phenomenon of the upper leather ring 8 between the upper pressure roller 4 and the adjusting roller 16, thereby transferring the "arching" below the upper leather ring 8 to the upper part, quickly eliminating the "arching" phenomenon below, and the same is true for the lower leather ring 7.
