Description

Technical Field

[0001] The invention relates to the technical field of spinning equipment, in particular to a sizing machine with a yarn break detection function. Background Art

[0002] Sizing is a very old yarn processing process. The earliest sizing process recorded in ancient books can be traced back to the Yuan Dynasty 750 years ago. People have long discovered in production practice that the warp yarn will produce a lot of fluff or even breakage problems after repeated friction, stretching, and bending of the warp yarn on the loom. The unsized single yarn fibers are not firmly held together, and there are more surface hairiness, which is difficult to weave. By applying sizing to the warp yarn, its weavability is improved. After sizing, part of the sizing liquid penetrates between the fibers, and the other part adheres to the surface of the warp yarn. The sizing that mainly penetrates between the fibers is called penetration sizing, and the sizing that mainly adheres to the surface of the warp yarn is called covering sizing. The sizing machine is an industrial machine for sizing yarn fabrics, mainly used to spin fibers into sized yarn. The current sizing equipment cannot promptly alarm and shut down when the yarn breaks, and manual supervision is required beside the equipment, which cannot achieve fully automated production. Summary of the invention

[0003] The object of the present invention is to provide a sizing machine with a yarn break detection function to solve the problems raised in the above background technology.

The sizing component immerses the yarn in the adhesive slurry to make the yarn absorb the adhesive, and the resistance drying furnace dries the yarn. With the loss of the adhesive slurry, the liquid level detection mechanism can use a float to float on the adhesive slurry. After the height of the float is reduced, the control system is triggered, and the control system continues to add adhesive slurry to the slurry pool through the feeding pipe.

The upper bevel gear drives the lower bevel gear to rotate synchronously through the side bevel gear. The upper bevel gear and the lower bevel gear have the same speed but opposite directions, that is, the upper paddle wheel and the lower paddle wheel rotate in opposite directions at the same time, and the upper paddle wheel and the lower paddle wheel fluctuate viscous oil at the same time. The viscous oil generates resistance to the rotation of the upper and lower paddle wheels, that is, the speed of the winding wheel is limited. Since the equipment for winding the yarn is pulling, there is also friction between the winding wheel and the yarn, and the yarn between the winding wheel and the equipment for winding the yarn is tightened to generate a certain tension.

[0007] Furthermore, the interior of the damper is filled with viscous oil, and the upper bevel gear is coaxially connected to the winding wheel. In order to prevent the viscous oil from generating rotational inertia after being stirred by the paddle wheel for a period of time and losing the function of tensioning the yarn, the upper paddle wheel and the lower paddle wheel are used to stir the viscous oil in opposite directions at the same time, offsetting the flow inertia of the viscous oil, so that the interior of the viscous oil always maintains a turbulent state, thereby maintaining rotational resistance to the winding wheel.

If the yarn breaks, the tension on the yarn disappears and the adapter block is immediately reset driven by the coil spring. The adapter block contacts the conductive sheet in the yarn dipping plate, so that the electromagnet circuit is connected. The electromagnet is energized to generate magnetism and adsorb the lock. The lock is sucked into the storage groove and contacts the yarn dipping plate. The yarn dipping plate is reset under the pull of the weight.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0013] By using the upper paddle wheel and the lower paddle wheel to stir the viscous oil in opposite directions at the same time, the flow inertia of the viscous oil is offset against each other, so that the interior of the viscous oil is always kept in a turbulent state, and then the rotational resistance to the winding wheel is maintained to achieve the tension of the yarn.

The sizing component 2 immerses the yarn in the adhesive slurry to make the yarn absorb the adhesive, and the resistance drying furnace 3 dries the yarn. With the loss of the adhesive slurry, the liquid level detection mechanism can use a float to float on the adhesive slurry. After the height of the float is reduced, the control system is triggered, and the control system continues to replenish the adhesive slurry into the slurry pool 13 through the feeding pipe.

[0024] The yarn guide assembly 1 includes an upper yarn guide plate 4, a lower yarn guide plate 5, a winding wheel 6 and a damper 7. The upper yarn guide plate 4, the lower yarn guide plate 5 and the winding wheel 6 are arranged above the bracket, and the damper 7 is arranged below the bracket. The upper yarn guide plate 4 and the lower yarn guide plate 5 are located on the same side, and the lower yarn guide plate 5 is arranged on the side close to the sizing assembly 2. The winding wheel 6 is provided with a plurality of vertically arranged anti-skid rubber strips. The winding wheel 6 passes through the bracket and is connected to the damper 7. The damper 7 is hollow inside and the damper An upper bevel gear 8, a side bevel gear 10 and a lower bevel gear 11 are provided for internal rotation of the device 7. The upper bevel gear 8 is installed above the lower bevel gear 11. The side bevel gear 10 is meshed with the upper bevel gear 8 and the lower bevel gear 11. An upper paddle wheel 9 is coaxially provided at one end of the upper bevel gear 8 close to the lower bevel gear 11. A lower paddle wheel 12 is coaxially provided at one end of the lower bevel gear 11 close to the upper bevel gear 8. The interior of the damper 7 is filled with viscous oil, and the upper bevel gear 8 is coaxially connected to the winding wheel 6.

[0025] When the yarn winding device pulls the yarn, the yarn is tightened. Due to the friction between the anti-slip rubber strip and the yarn, the yarn drives the winding wheel 6 to rotate, and the winding wheel 6 drives the upper bevel gear 8 to rotate. The upper bevel gear 8 drives the lower bevel gear 11 to rotate synchronously through the side bevel gear 10. The upper bevel gear 8 and the lower bevel gear 11 have the same speed and opposite direction, that is, the upper paddle wheel 9 and the lower paddle wheel 12 rotate in opposite directions at the same time, and the upper paddle wheel 9 and the lower paddle wheel 12 fluctuate the viscous oil at the same time. The viscous oil produces resistance to the rotation of the upper paddle wheel 9 and the lower paddle wheel 12, that is, the winding wheel 6 The rotation speed is limited. Since the device for winding the yarn is pulling, there is friction between the winding wheel 6 and the yarn. The yarn between the winding wheel 6 and the device for winding the yarn is tightened to generate a certain tension. In order to prevent the viscous oil from generating rotational inertia after being stirred by the paddle wheel for a period of time and losing the function of tensioning the yarn, the upper paddle wheel 9 and the lower paddle wheel 12 are used to stir the viscous oil in opposite directions at the same time to offset the flow inertia of the viscous oil, so that the interior of the viscous oil is always in a turbulent state, thereby maintaining the rotational resistance to the winding wheel 6.

[0026] A fixed saddle roller 14 is rotatably mounted on one side of the slurry pool 13 close to the yarn guide assembly 1, and a fixed extrusion roller 15 is rotatably mounted on one side of the slurry pool 13 close to the resistance drying furnace 3. A dipping plate 18 is located between the fixed saddle roller 14 and the fixed extrusion roller 15. A buffer plate 23 is arranged on the vertical slide rail 19. The buffer plate 23 is made of rubber material. A pressure sensor is arranged inside the buffer plate 23. The pressure sensor is connected to an alarm system through a control system. The dipping plate 18 is L-shaped, and one end of the dipping plate 18 is A slot is provided, in which a transfer block 20 and a limit pin 21 are installed. The transfer block 20 is rotatably installed in the slot. A movable saddle roller 16 is rotatably installed on the transfer block 20. A movable extrusion roller 17 is rotatably installed on the other end of the dipping plate 18. A pair of cables 25 are connected to the upper end of the dipping plate 18. A pair of guide wheels 24 are arranged above the vertical slide rail 19. The pair of cables 25 pass through the top of the vertical slide rail 19. The pair of cables 25 respectively bypass the pair of guide wheels 24. The other ends of the pair of cables 25 are connected to a weight block 26.

[0027] The sizing assembly 2 includes a hydraulic cylinder 27 and a hook block 28, the hook block 28 is mounted on the hydraulic cylinder 27, the hook block 28 is located above the dipping plate 18, the hydraulic cylinder 27 is connected to the hydraulic control system, a storage groove is provided on the vertical slide rail 19, a lock buckle 22 is rotatably installed in the storage groove, a reset spring is provided between the lock buckle 22 and the storage groove, an electromagnet is also provided in the storage groove, a coil spring is installed at the transition between the adapter block 20 and the dipping plate 18, conductive sheets are provided in the adapter block 20 and the dipping plate 18, the two conductive sheets and the electromagnet are connected to the control system circuit, the fixed saddle roller 14 guides the yarn to the middle to prevent the yarn from escaping from the sizing assembly 2, and the control system drives the hydraulic cylinder 27 to drive the hook The block 28 moves downward, and the hook block 28 pushes the dipping plate 18 downward. The dipping plate 18 overcomes the gravity of the weight block 26 and moves downward until the dipping plate 18 passes over the lock buckle 22. The lock buckle 22 presses against the dipping plate 18 to prevent the dipping plate 18 from moving upward under the pull of the cable 25. The hydraulic cylinder 27 drives the hook block 28 to reset. The movable saddle roller 16 on the dipping plate 18 presses the yarn downward so that the yarn is immersed in the adhesive slurry. The movable extrusion roller 17 descends to a position flush with the fixed extrusion roller 15. The yarn soaked in the adhesive slurry passes between the movable extrusion roller 17 and the fixed extrusion roller 15. The excess adhesive slurry remaining on the yarn is squeezed off and drips back into the slurry pool 13 again.

[0028] Since there is tension on the yarn and since the adapter block 20 can deflect within a certain range, the movable saddle-shaped roller 16 will deflect obliquely upward after contacting the yarn. The adapter block 20 and the conductive sheets in the yarn dipping plate 18 are staggered with each other, and the circuit will not be connected. Once the yarn breaks, the tension on the yarn disappears, and the adapter block 20 is immediately reset under the drive of the coil spring. The adapter block 20 and the conductive sheets in the yarn dipping plate 18 are in contact with each other, so that the electromagnet circuit is connected, and the electromagnet is energized to generate magnetism and absorb the lock buckle 22. The lock buckle 22 is sucked into the storage groove and contacts the yarn dipping plate 18. The yarn dipping plate 18 is reset under the pull of the weight 26. After the yarn dipping plate 18 hits the buffer plate 23, the pressure sensor inside it is triggered. The pressure sensor triggers the alarm system through the control system to notify the operator of yarn breakage, thereby realizing the function of automatic yarn breakage detection and alarm.

[0029] The working principle of the present invention is as follows: the operator passes the yarn head to be sizing through the upper yarn guide plate 4, then winds it around the winding wheel 6 and passes it through the lower yarn guide plate 5, puts the yarn on the fixed saddle roller 14 and the fixed extrusion roller 15, and finally passes it through the resistance drying furnace 3, connects the yarn head with the equipment for winding the yarn, and the preliminary process of sizing is completed. The sizing component 2 immerses the yarn in the adhesive slurry to make the yarn absorb the adhesive, and the resistance drying furnace 3 dries the yarn. As the adhesive slurry is consumed, the liquid level detection mechanism can use a float to float on the adhesive slurry. After the height of the float is reduced, the control system is triggered, and the control system continues to replenish the adhesive slurry into the slurry pool 13 through the feeding pipe.

[0030] When the yarn winding device pulls the yarn, the yarn is tightened. Due to the friction between the anti-slip rubber strip and the yarn, the yarn drives the winding wheel 6 to rotate, and the winding wheel 6 drives the upper bevel gear 8 to rotate. The upper bevel gear 8 drives the lower bevel gear 11 to rotate synchronously through the side bevel gear 10. The upper bevel gear 8 and the lower bevel gear 11 have the same speed and opposite direction, that is, the upper paddle wheel 9 and the lower paddle wheel 12 rotate in opposite directions at the same time, and the upper paddle wheel 9 and the lower paddle wheel 12 fluctuate the viscous oil at the same time. The viscous oil produces resistance to the rotation of the upper paddle wheel 9 and the lower paddle wheel 12, that is, the winding wheel 6 The rotation speed is limited. Since the device for winding the yarn is pulling, there is friction between the winding wheel 6 and the yarn. The yarn between the winding wheel 6 and the device for winding the yarn is tightened to generate a certain tension. In order to prevent the viscous oil from generating rotational inertia after being stirred by the paddle wheel for a period of time and losing the function of tensioning the yarn, the upper paddle wheel 9 and the lower paddle wheel 12 are used to stir the viscous oil in opposite directions at the same time to offset the flow inertia of the viscous oil, so that the interior of the viscous oil is always in a turbulent state, thereby maintaining the rotational resistance to the winding wheel 6.

[0031] The fixed saddle roller 14 guides the yarn toward the middle to prevent the yarn from escaping from the sizing assembly 2. The control system drives the hydraulic cylinder 27 to drive the hook block 28 to move downward. The hook block 28 pushes the dipping plate 18 downward. The dipping plate 18 overcomes the gravity of the weight 26 and moves downward until the dipping plate 18 passes over the lock buckle 22. The lock buckle 22 presses against the dipping plate 18 to prevent the dipping plate 18 from moving upward under the pull of the cable 25. The hydraulic cylinder 27 drives the hook block 28 to reset. The movable saddle roller 16 on the dipping plate 18 presses the yarn downward so that the yarn is immersed in the adhesive slurry. The movable extrusion roller 17 descends to a position flush with the fixed extrusion roller 15. The yarn soaked in the adhesive slurry passes between the movable extrusion roller 17 and the fixed extrusion roller 15. The excess adhesive slurry remaining on the yarn is squeezed off and drips back into the slurry pool 13 again.

[0032] Since there is tension on the yarn and since the adapter block 20 can deflect within a certain range, the movable saddle-shaped roller 16 will deflect obliquely upward after contacting the yarn. The adapter block 20 and the conductive sheets in the yarn dipping plate 18 are staggered with each other, and the circuit will not be connected. Once the yarn breaks, the tension on the yarn disappears, and the adapter block 20 is immediately reset under the drive of the coil spring. The adapter block 20 and the conductive sheets in the yarn dipping plate 18 are in contact with each other, so that the electromagnet circuit is connected, and the electromagnet is energized to generate magnetism and absorb the lock buckle 22. The lock buckle 22 is sucked into the storage groove and contacts the yarn dipping plate 18. The yarn dipping plate 18 is reset under the pull of the weight 26. After the yarn dipping plate 18 hits the buffer plate 23, the pressure sensor inside it is triggered. The pressure sensor triggers the alarm system through the control system to notify the operator of yarn breakage, thereby realizing the function of automatic yarn breakage detection and alarm.
