Description

Technical Field

[0001] This invention relates to a welding and assembly device for a texturing machine hot rail. Background Technology

[0002] A texturing machine is a textile machine that can process untwisted yarns such as polyester (POY) and polypropylene into elastic yarns with medium to low elasticity through false twisting. The heating chamber of the texturing machine is mainly used to heat the yarn as it passes through the heating rail. The existing heating rail is assembled from components such as the heating rail profile, back plate, and air inlet pipe. During the production of the heating rail, the back plate and the heating rail profile need to be welded together. The current method is to manually spot weld the entire heating rail profile and back plate together, with a spacing of about 100mm (about 40 weld points), then place it in a U-shaped clamp, clamp it with a cylinder, and then use a double-headed welding device to move linearly, carrying two argon arc welding guns to fully weld the joint between the heating rail profile and the back plate. After welding, the cylinder is released, and finally the workpiece is removed. However, the above method has the following drawbacks: it requires multiple manual spot welding operations, which is time-consuming and labor-intensive, and manual spot welding can result in uneven joint surfaces, affecting product quality. Summary of the Invention

[0003] The purpose of this invention is to provide a welding and assembly equipment for the hot rail of a texturing machine. It has a reasonable structure, can avoid multiple spot welding operations, reduce labor costs, and at the same time help improve production efficiency and product quality.

[0004] To achieve the above objectives, the technical solution of the present invention is to design a welding assembly equipment for a texturing machine hot rail, including a frame, and a placement mechanism, a pushing mechanism and a welding mechanism disposed on the frame;

[0005] The placement mechanism is used to place the texturing machine hot rail to be welded. The texturing machine hot rail includes a hot rail profile and a back plate. The hot rail profile has an upward-facing groove, and the bottom of the hot rail profile is provided with a wire guide groove. The back plate is disposed in the opening of the groove.

[0006] The pushing mechanism is used to push the texturing machine hot rail to the welding mechanism;

[0007] The welding mechanism includes a positioning assembly and two welding torches. The positioning assembly includes a base plate and a pair of side plates disposed on top of the base plate. The base plate is fixed to the frame. A channel for the hot rail of the texturing machine to pass through is formed between the pair of side plates. Several positioning wheels and several pressure rollers are arranged in the channel along its length. The positioning wheels are rotatably connected between the pair of side plates, and each positioning wheel is located below the hot rail profile. The pressure rollers are arranged along the length of the channel, and each pressure roller is located above the rear plate. Each pressure roller applies pressure to the rear plate and includes an axle and a rotating mechanism. The pressure roller body is mounted on the axle. A pair of side plates are inserted into each end of the axle. The side plates are provided with floating grooves for the axle to be inserted. A compression spring is connected between the axle and the top wall of the floating groove. The top of the pair of side plates is provided with clearance notches. Two welding torches pass through the clearance notches of the pair of side plates and extend into the channel. The welding torches are used to fully weld the joint between the hot rail profile and the back plate. Cooling stations are provided on the opposing inner sides of the pair of side plates. Along the traveling direction of the hot rail of the texturing machine, the cooling stations are located downstream of the welding torches and are used to install a spray water cooling device.

[0008] Preferably, the pair of side plates are provided with a plurality of ball grooves on their opposing inner sides. The plurality of ball grooves are arranged along the length of the channel. Each ball groove is located between the positioning wheel and the pressure wheel, and a side limiting ball is installed in each ball groove. The side limiting ball can roll in the ball groove, and the side limiting ball partially protrudes from the inner surface of the side plate.

[0009] Preferably, the placement mechanism includes a pair of baffles and a plurality of support wheels rotatably connected between the pair of baffles. The pair of baffles is fixed on the frame, and a placement groove for accommodating the hot rail of the texturing machine is formed between the pair of baffles. The placement groove is connected to the entrance end of the channel. The plurality of support wheels are arranged along the length of the placement groove, and each support wheel is located below the hot rail profile.

[0010] Preferably, both the positioning wheel and the support wheel have positioning protrusions on their outer peripheral surfaces that can be embedded in the guide wire groove.

[0011] Preferably, the pushing mechanism includes a slide rail, a movable plate, a rack, and a push rod. The slide rail and rack are fixed on the frame. The movable plate is slidably connected to the slide rail via a slider. The movable plate is equipped with a drive motor. The output end of the drive motor is connected to a gear that meshes with the rack. One end of the push rod is fixed to the movable plate, and the other end of the push rod is used to contact the hot rail of the texturing machine.

[0012] Preferably, the frame is provided with a discharge trough, which is connected to the outlet end of the channel.

[0013] Preferably, the movable plate is connected to a cable chain.

[0014] The advantages and beneficial effects of this invention are as follows: It provides a welding and assembly device for a texturing machine hot rail. When using this welding and assembly device, it is only necessary to spot weld the hot rail profile and the end of the back plate together, avoiding multiple spot welding operations, greatly reducing spot welding time and labor costs, thereby improving production efficiency. It can also avoid unevenness between the back plate and the hot rail profile caused by manual spot welding, which is conducive to improving product quality. In addition, by setting a spray water cooling device, the hot rail of the texturing machine that has been welded is cooled by water to release welding stress, which helps to reduce the deformation of the hot rail of the texturing machine.

[0027] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0028] The specific technical solution of this invention is as follows:

[0029] like Figures 1 to 12 As shown,

[0030] A welding assembly device for a hot rail of a texturing machine includes a frame 100, and a placement mechanism 200, a pushing mechanism 300 and a welding mechanism 400 disposed on the frame.

[0031] The placement mechanism 200 is used to place the texturing machine hot rail to be welded. The texturing machine hot rail includes a hot rail profile 1 and a back plate 2. The hot rail profile 1 has an upward-facing groove 11, and the bottom of the hot rail profile 1 is provided with a wire guide groove 12. The back plate 2 is disposed in the opening of the groove 11.

[0032] The pushing mechanism 300 is used to push the texturing machine hot rail to the welding mechanism 400;

[0033] The welding mechanism 400 includes a positioning assembly and two welding torches 401. The positioning assembly includes a base plate 402 and a pair of side plates 403 disposed on the top of the base plate 402. The base plate 402 is fixed to the frame 100. A channel 404 for the hot rail of the texturing machine to pass through is formed between the pair of side plates 403. The channel 404 is provided with a plurality of positioning wheels 405 and a plurality of pressure wheels. The plurality of positioning wheels 405 are arranged along the length of the channel 404 and are rotatably connected between the pair of side plates 403. Each positioning wheel 405 is located below the hot rail profile 1. The plurality of pressure wheels are arranged along the length of the channel 404 and are located above the rear plate 2. Each pressure wheel is used to apply pressure to the rear plate 2. Each pressure wheel includes a wheel axle 406 and a rotating sleeve. The wheel axle 406 has a pressure roller body 407. A pair of side plates 403 are inserted into both ends of the wheel axle 406. The side plates 403 are provided with floating grooves 408 for the wheel axle 406 to be inserted. A compression spring 409 is connected between the wheel axle 406 and the top wall of the floating groove 408. The top of the pair of side plates 403 is provided with clearance notches 410. The two welding torches 401 pass through the clearance notches 410 of the pair of side plates 403 and extend into the channel 404. The welding torches 401 are used to fully weld the joint between the hot rail profile 1 and the rear plate 2. The pair of side plates 403 are provided with cooling stations 411 on their opposing inner sides. Along the traveling direction of the hot rail of the texturing machine, the cooling stations 411 are located downstream of the welding torches 401 and are used to install a spray water cooling device. By adopting the above scheme, when the welding assembly equipment is in use: firstly, the ends of the hot rail profile 1 and the back plate 2 are manually spot-welded together, and the back plate 2 is kept outside the opening of the groove 11 on the hot rail profile 1. Then, the hot rail is placed in the placement mechanism 200, with the spot-welded end of the hot rail facing the welding mechanism 400. Then, the hot rail placed in the placement mechanism 200 is pushed to the welding mechanism 400 by the pushing mechanism 300, and the hot rail moves in the channel 404 of the welding mechanism 400. When the hot rail enters the channel 404, the positioning wheel 405 supports the hot rail profile 1, and the pressure... The wheel body 407 applies pressure to the rear plate 2 through the elastic force of the compression spring 409, causing the rear plate 2 to gradually engage with the opening of the groove 11 and making the outer surface of the rear plate 2 flush with the surface of the opening of the groove 11, so as to realize the assembly of the rear plate 2 and the hot rail profile 1. Then, the welding gun 401 is used to fully weld the joint between the assembled part of the hot rail profile 1 and the rear plate 2. After the welding is completed, the hot rail will be cooled by a spray water cooling device to release the welding stress and reduce the deformation of the hot rail. In addition, the hot rail is pressed by the pressure roller and the positioning roller 405 throughout the welding process, which helps to further prevent the hot rail from welding deformation problems.

[0034] Furthermore, the pair of side plates 403 are respectively provided with a plurality of ball grooves on their opposing inner sides. The plurality of ball grooves are arranged along the length direction of the channel 404. Each ball groove is located between the positioning wheel 405 and the pressure wheel, and a side limiting ball 412 is installed in each ball groove. The side limiting ball 412 can roll in the ball groove, and the side limiting ball 412 partially protrudes from the inner surface of the side plate 403. By adopting the above scheme, when the hot rail moves in the channel 404, the side limiting ball 412 can contact the side of the hot rail profile 1, thereby preventing the hot rail from shifting laterally.

[0035] Furthermore, the placement mechanism 200 includes a pair of baffles 201 and a plurality of support wheels 202 rotatably connected between the pair of baffles 201. The pair of baffles 201 are fixed on the frame 100, and a placement groove 203 for accommodating the hot rail of the texturing machine is formed between the pair of baffles 201. The placement groove 203 is connected to the entrance end of the channel 404. The plurality of support wheels 202 are arranged along the length direction of the placement groove 203, and each support wheel 202 is located below the hot rail profile 1. By adopting the above scheme, the hot rail can be placed into the placement groove 203 of the placement mechanism 200, and the hot rail profile 1 is supported by the support wheels 202. The hot rail can smoothly enter the channel 404 under the push of the pushing mechanism 300.

[0036] Furthermore, both the positioning wheel 405 and the support wheel 202 are provided with positioning protrusions 413 that can be embedded in the wire guide groove 12 on their outer peripheral surfaces. By adopting the above solution, it is beneficial to further prevent the hot rail from shifting laterally, enhance the positioning effect of the hot rail, and improve the welding accuracy.

[0037] Furthermore, the pushing mechanism 300 includes a slide rail 301, a moving plate 302, a rack 303, and a push rod 304. The slide rail 301 and the rack 303 are fixed on the frame 100. The moving plate 302 is slidably connected to the slide rail 301 via a slider 305. The moving plate 302 is equipped with a drive motor 306. The output end of the drive motor 306 is connected to a gear that meshes with the rack 303. One end of the push rod 304 is fixed to the moving plate 302, and the other end of the push rod 304 is used to contact the hot rail of the texturing machine. By adopting the above scheme, the drive motor 306 is controlled to drive the gear to rotate. Since the gear meshes with the rack 303 and the rack 303 is fixed on the frame 100, and the drive motor 306 is fixed on the moving plate 302, when the drive motor 306 runs, it will drive the moving plate 302 and the push rod 304 to move. After the push rod 304 contacts the hot rail, it will push the hot rail to move, thereby realizing the pushing of the hot rail.

[0038] Furthermore, the frame 100 is provided with a discharge trough 3, which is connected to the outlet end of the channel 404. By adopting the above solution, after the hot rail is welded, it will be moved out from the outlet end of the welding mechanism 400 and into the discharge trough 3, so that the operator can take out the hot rail from the discharge trough 3.

[0039] Furthermore, the movable plate 302 is connected to a cable chain 307. By adopting the above solution, the cable chain 307 accommodates and protects the connecting cable.

[0040] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
