Description

A power failure protection device for a sizing machine Technical Field

[0001] This utility model relates to the field of sizing machine technology, and in particular to a power outage protection device for a sizing machine. Background Technology

[0002] In textile operations, sizing machines are key equipment for enhancing the weavability of yarns. By uniformly applying sizing agent to the surface of warp yarns and drying it, the strength, abrasion resistance, and antistatic properties of the yarn are significantly improved, thereby reducing the breakage rate during weaving and improving production efficiency and fabric quality.

[0003] During the operation of a sizing machine, power outages often occur due to external power supply system failures or internal electrical faults.

[0004] Traditional sizing machines lack power outage protection measures. After a power outage, the warping beam loses its braking, causing the yarn to continue to unwind significantly due to inertia, becoming loose or tangled with adjacent yarns, which causes problems for subsequent operations. Summary of the Invention

[0005] The purpose of this invention is to provide a power outage protection device for a sizing machine, which can effectively stop the sizing machine in case of power failure.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a power failure protection device for a sizing machine, comprising a first mounting frame, yarn rollers rotatably mounted on the first mounting frame at both ends, and a protection component, wherein a synchronization cylinder is coaxially fixed on the side of the yarn rollers;

[0007] The protective components include a support frame, a buffer component, a fixing component, and a lifting component. The support frame is fixedly connected to the outside of the first mounting frame. The buffer component is set on the support frame. When the power is off, the yarn roller is gradually slowed down and stopped through the buffer component. The fixing component is connected to the buffer component, and the lifting component is located below the buffer component.

[0008] A further feature of this invention is that the buffer assembly includes a buffer frame and an installation assembly whose bottom end is fixed to the support frame.

[0009] By adopting the above technical solution, the buffer frame can provide emergency stop and deceleration buffer for the rotating synchronous cylinder.

[0010] A further feature of this invention is that the mounting assembly includes a rotating shaft with one end rotatably connected to the buffer frame, a torsion spring for assisting the buffer frame in rotating and resetting, and a base rotatably connected to the other end of the rotating shaft.

[0011] By adopting the above technical solution, the buffer frame can be moved into the synchronous cylinder for contact.

[0012] A further feature of this invention is that the bottom end of the base is fixedly connected to the support frame, and a protruding strip is fixedly provided on the inner wall of the synchronization cylinder.

[0013] By adopting the above technical solution, when the synchronous cylinder rotates, the buffer frame will come into contact with the convex strip after rotating downward through the torsion spring.

[0014] A further feature of this invention is that the fixing component includes a second mounting bracket fixed at its bottom end to the support frame and an electromagnetic chuck fixed at the upper part of the second mounting bracket.

[0015] The above technical solution is used to position the buffer frame.

[0016] A further feature of this invention is that the electromagnetic chuck is magnetically connected to the outer wall of the buffer frame.

[0017] The above technical solution is used to achieve positioning via an electromagnetic chuck.

[0018] A further feature of this invention is that a groove is provided on the side of the second mounting bracket near the lifting assembly.

[0019] By adopting the above technical solution, space support is provided for the installation of the improved components.

[0020] A further feature of this invention is that the lifting assembly includes a push block and a cylinder with a piston rod fixedly connected to the push block.

[0021] By adopting the above technical solution, the buffer frame is pushed back to its original position, so that the outer side of the buffer frame is magnetically attracted to the electromagnetic chuck after being powered on.

[0022] A further feature of this invention is that the outer side of the cylinder is fixedly connected to the groove via a support.

[0023] By adopting the above technical solution, the cylinder can be used stably.

[0024] A further feature of this invention is that the material of the raised strip is rubber or silicone.

[0025] By adopting the above technical solution, the contact deceleration effect with the buffer frame can be improved.

[0026] The beneficial effects of this utility model are:

[0027] After a power outage, the electromagnetic chuck will respond to the power failure, allowing the buffer frame to rotate towards the synchronization drum through the elastic force of the torsion spring. This allows the buffer frame to extend into the synchronization drum and contact the synchronization drum and the convex strip, thus enabling the synchronization drum to be flexibly buffered and decelerated after being subjected to force. This prevents the yarn roller from rotating excessively due to inertia after a power outage, which could cause yarn misalignment. At the same time, after power is restored, the buffer frame can also be quickly reset through the lifting component, operating in an automated manner to improve the timeliness and convenience of emergency stop protection.

Detailed Implementation

[0034] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] This utility model embodiment specifically provides a power outage protection device for a sizing machine. Please refer to Figures 1-4. It includes a first mounting frame 1, yarn rollers 2 rotatably mounted on the first mounting frame 1 at both ends, and a protection component 3. A synchronization cylinder 21 is coaxially fixed on the side of the yarn rollers 2.

[0036] The protection component 3 includes a support frame 31, a buffer component 32, a fixing component 33, and a lifting component 34. The support frame 31 is fixedly connected to the outside of the first mounting frame 1. The buffer component 32 is set on the support frame 31. When the power is off, the yarn roller 2 is gradually slowed down and stopped through the buffer component 32. The fixing component 33 is connected to the buffer component 32. The lifting component 34 is located below the buffer component 32 so that the buffer component 32 can be reset in time after emergency stop through the lifting component 34.

[0037] Furthermore, the buffer assembly 32 includes a buffer frame 321 and a mounting assembly 322 whose bottom end is fixed to the support frame 31. The buffer frame 321 moves on the mounting assembly 322, thereby causing the buffer frame 321 to perform emergency stop and deceleration buffering on the rotating synchronous cylinder 21.

[0038] The mounting component 322 includes a rotating shaft 323 rotatably connected to the buffer frame 321 at one end, a torsion spring 324 for helping the buffer frame 321 to rotate and reset, and a base 325 rotatably connected to the other end of the rotating shaft 323, so that the buffer frame 321 can rotate with the rotating shaft 323 as the fulcrum. The torsion spring 324 is normally in a compressed state. When the buffer frame 321 is separated from the fixing component 33, the buffer frame 321 can quickly rotate downward by the elastic force of the torsion spring 324, so that the buffer frame 321 can move into the inside of the synchronization cylinder 21 for contact, thereby slowing down the synchronization cylinder 21.

[0039] In practice, the bottom end of the base 325 is fixedly connected to the support frame 31, and the inner wall of the synchronization cylinder 21 is fixedly provided with a protrusion 22. The protrusion 22 is arranged in a circumferential array along the inner wall of the synchronization cylinder 21. When the synchronization cylinder 21 rotates, the buffer frame 321 rotates downward through the torsion spring 324 and comes into contact with the protrusion 22, so that the buffer frame 321 slides along the inner wall of the synchronization cylinder 21 and the surface of the protrusion 22, thereby achieving the effect of decelerating the synchronization cylinder 21.

[0040] Furthermore, the fixing component 33 includes a second mounting bracket 331 fixed at the bottom end on the support frame 31 and an electromagnetic chuck 332 fixed at the upper part of the second mounting bracket 331. The electromagnetic chuck 332 is an existing component that is synchronized with the power-on state of the sizing machine. After being powered on, it can generate magnetic attraction to position the buffer frame 321.

[0041] The buffer frame 321 is made of iron, and the electromagnetic chuck 332 is magnetically connected to the outer wall of the buffer frame 321, so that after the buffer frame 321 is vertically rotated upward, it can be positioned by the electromagnetic chuck 332.

[0042] During implementation, if a power outage occurs in the workshop, the electromagnetic chuck 332 will be de-energized, causing the buffer frame 321 to rotate toward the synchronous cylinder 21 and make contact with the deceleration mechanism through the action of the torsion spring 324.

[0043] The first mounting bracket 1 has a groove 11 on the side near the lifting component 34 to provide space support for the installation of the lifting component 34.

[0044] Furthermore, the lifting assembly 34 includes a push block 341 and a cylinder 342 whose piston rod is fixedly connected to the push block 341. When the buffer frame 321 is de-energized and rotates, its bottom side will contact the upper end of the push block 341. Therefore, when the buffer frame 321 needs to be reset after being energized, the cylinder 342 only needs to drive the push block 341 to move upward, thereby pushing the buffer frame 321 to reset, so that the outer side of the buffer frame 321 is magnetically attracted to the energized electromagnetic chuck 332.

[0045] The cylinder 342 is fixedly connected to the groove 11 via a support 343 on its outer side, thereby enabling the cylinder 342 to be used stably.

[0046] During implementation, the material of the protrusion 22 is rubber or silicone, which has good elasticity and can improve the deceleration effect of contact with the buffer frame 321.

[0047] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
