Description

Technical Field

[0001] The utility model relates to the technical field of a tool for removing a hot rail in a hot box slot of a texturing machine, in particular to a tool for removing and assembling a hot rail in a high-temperature short hot box of a TMT1500 texturing machine. Background Art

[0002] The high temperature short hot box of TMT1500 "T" type texturing machine is 100cm long, 19cm wide and 25.5cm high. A non-contact hot rail is installed in the hot box slot. The hot rail is composed of long and short areas (the side view of the long and short hot rail is as shown in the figure). Figure 3 and Figure 4 As shown in the figure, there are 16 porcelain parts evenly distributed inside, including 9 long zone hot rails and 7 short zone hot rails. Since DTY products are stretched and deformed by high temperature heating in the hot box for a long time, the residual monomers and coke left by the wire through the wire path need to be regularly maintained and cleaned. During the operation, the hot rails need to be disassembled and installed. The cleaning and maintenance of this component is an important indicator for the production of high-quality DTY.

[0003] At present, the original disassembly tool of this component is a T-shaped wrench. Since there are two parallel hot rails in a box, they need to be pulled one after the other during disassembly. When using the original wrench, the handle is extended back and forth between the two hot rails. Because the space is too small, it will cause friction, making the whole operation slow or even need to be suspended, which greatly reduces the work efficiency. At the same time, the uneven extraction force of the hot rail strip causes the parts to fall off and be damaged. Therefore, a convenient and effective hot rail disassembly tool that can not only improve work efficiency but also maintain equipment parts and improve product quality has become an urgent need for operators. Summary of the invention

[0004] In order to solve one or some technical problems existing in the prior art, the purpose of the present application is to provide a hot rail disassembly and assembly tool for a high-temperature short hot box of a TMT1500 texturing machine, which can quickly complete the disassembly and installation of the hot rail, effectively disassemble and clean the residual monomers and coke in the hot box wire path, improve work efficiency and maintain mechanical equipment, effectively avoid damage and deformation during operation, achieve energy saving and consumption reduction, improve product quality, and provide effective protection for equipment components while being convenient.

[0023] like Figure 1 As shown, a hot rail disassembly and assembly tool for a high-temperature short hot box of a TMT1500 texturing machine comprises a long hand-held portion 2, a metal rod 3 with one end fixed to one side of the hand-held portion 2, and a hook 4 arranged at the front end of the metal rod 3. The hand-held portion 2 and the metal rod 3 with the hook 4 are arranged in a straight line, the hook 4 is bent toward one side of the hand-held portion 2, and the width of the hook 4 is ≤ the width of the hand-held portion 2.

[0024] In actual practical process, Figure 3The short zone hot rail and the long zone hot rail are installed inside the hot box body, and the hot rail porcelain parts are fixed at the bottom of the entire rail. The POY tow enters the hot box after being stretched by a roller, undergoes high temperature stretching deformation, and then undergoes twisting, untwisting, cooling and other processes. When it is necessary to disassemble the short zone hot rail and the long zone hot rail, first open the relevant fixed porcelain parts at the front and rear ports of the hot box slot, so that the entire hot box body is in a state where the hot rail track can enter and exit. Then hold the handheld part 2 with the right hand, and use the handheld part 2 to extend the hook 4 at the front end of the metal rod 3 and align it with the hot rail bayonet to be disassembled, and finally pull it out. The handheld part 2 and the metal rod 3 with the hook 4 are arranged in a straight line, and the hook 4 is bent toward one side of the handheld part 2, which can make it more convenient to operate and have a smaller maximum width. In particular, when the width of the hook 4 is ≤ the width of the handheld part 2, the entire structure can be narrower in maximum width, making it more convenient to extend the hook 4. The internal hot rail can be easily and quickly pulled out of the hot box slot, so that the hot rail can be removed for cleaning, maintenance or replacement. The same is true for the installation of the cleaned hot rail. First, hold the hot rail and insert it into the hot box slot, and then use the disassembly and assembly tool to push it until the hot rail is fixed in the position and locked. The disassembly and assembly tool can quickly complete the removal and installation. Compared with the original tools, it can effectively avoid damage and deformation during operation, and effectively protect the equipment components while being convenient. It can also be operated repeatedly for a long time when the equipment is operated on site. It is very convenient to use, which shortens the operation time and prolongs the service life of the hot rail. It improves the stability of the wire path in the hot box slot, improves product quality, and improves work efficiency.

[0025] A further improvement is that the metal rod 3 is a welding rod, the hook 4 is formed by bending the front end of the welding rod, and the angle between the hook 4 and the metal rod 3 is 85-90°.

[0026] After testing and actual use, it was found that the ordinary metal rod 3 has a low melting point and is easily straightened by the hook 4 during the pulling process due to the high heat during operation, which makes it impossible to stably pull out the hot rail, has a short service life and is not practical to operate. Therefore, when selecting the metal rod 3, electric welding rods are directly used instead. The welding rods have sufficient rigidity, hardness and high melting point. After the metal rod 3 with the hook 4 is made, it can effectively ensure that it will not be deformed when the hot rail is pulled.

[0027] A further improvement is that the hand-held part 2 is a hollow aluminum tube with a diameter of 0.8 to 1.5 cm.

[0028] The hand-held part 2 is made of a hollow aluminum tube with a diameter of 0.8 to 1.5 cm. Its length is based on convenience in holding, and the overall weight is lighter. Generally, the diameter of the hollow aluminum tube is 1 cm. While ensuring its overall weight is lighter, it can be convenient to hold and is more convenient to obtain materials. It can be prepared using old hollow aluminum tubes of existing equipment.

[0029] Further improvement is as follows: Figure 2 As shown, a hook 6 is further provided at the end of the metal rod 3 , and the bending angle of the hook 6 is 270°.

[0030] In order to ensure that the metal rod 3 does not separate from the handheld part 2 during the process of pulling the hot rail, a hook 6 is bent at the end of the metal rod 3, and the bending angle of the hook 6 is 270°. The bent part of the hook 6 is hooked into the inner hole of the hollow aluminum tube, thereby effectively avoiding the problem of separation between the two during practical use, so that the metal rod 3 is more stable when used with the handheld part 2, and the hook 6 has a higher fit.

[0031] As a further improvement, a fixing strap 1 is provided between the metal rod 3 and the hand-held part 2 , the fixing strap 1 is made of an electrical insulating tape, and a heat insulation layer is formed between the metal rod 3 and the outer side of the hand-held part 2 through the fixing strap 1 .

[0032] The metal rod 3 and the hand-held part 2 are fixed by a fixing strap 1, which has lower cost and is more convenient to replace the metal rod 3. The fixing strap 1 adopts an electrical insulating tape, which can not only play the role of insulation and heat insulation, but also ensure comfort when holding and better anti-slip performance.

[0033] As a further improvement, an inwardly recessed limiting groove 5 is provided on the outer side of the hand-held portion 2 , and the metal rod 3 is installed along the limiting groove 5 for limiting position.

[0034] Since the hand-held portion 2 and the metal rod 3 are both cylindrical structures, they are prone to sliding left and right during use after being bound by the fixing strap 1. Therefore, an inwardly recessed limiting groove 5 is formed on the outer side of the hand-held portion 2, so that the metal rod 3 is installed along the limiting groove 5 and limited, and then bound by the fixing strap 1, so that the metal rod 3 will not slide left and right during use.

[0035] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
