Description

Technical Field

[0001] This invention relates to a welding device, specifically a welding device for spiked rollers, belonging to the field of welding processing technology. Background Technology

[0002] The barbed roller is a core component of textile equipment such as carding machines. It uses metal needle-cloth teeth to squeeze, pierce, and tear the cotton layer, achieving the dual functions of fiber combing and impurity removal. In the manufacturing process of barbed rollers, a smooth roller is first produced. Then, according to the required barbed layout, the barbs are welded one by one onto the roller to form the barbed roller. Currently, welding is mostly done manually. However, due to the large number of barbs, limited operating space, and varying worker skill levels, the welding results are inconsistent, affecting both production efficiency and quality. While some auxiliary equipment exists to assist manual barbed welding, the welding quality is still affected by the worker's skill level. Furthermore, the distribution of barbs on the roller is not uniform during welding; it can be linear, spiral, or wavy. Adjustments to the roller are required during welding, making manual operation with welding equipment slow and inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide a welding device for spiked rollers to solve the above-mentioned problems. The device can automatically adjust the angle and fix the spiked rollers, and automatically weld them after placing the spikes, thereby improving the processing efficiency of spiked rollers, reducing labor intensity, improving welding quality, and enhancing applicability to processing spiked rollers with different spike distributions.

[0004] This invention achieves the above-mentioned objective through the following technical solution: a welding device for a spiked roller, comprising a base, a limiting and fixing component, a spiked roller, a welding component, and a control host. The base has an elongated structure, and a boss parallel to the elongated side is provided at the middle position of the upper surface of the base. An electric slide rail is symmetrically fixedly mounted on the upper surface of the base, with the bosses forming the bosses. Both ends of the welding component are fixedly mounted on the moving ends of the electric slide rails for adjusting different welding positions on the spiked roller. The welding component includes a gate-shaped retainer, with a sleeve for limiting the spikes on the spiked roller fixedly mounted at the center of the upper end of the retainer. A welding head for welding spikes onto the spiked roller is rotatably mounted on the upper inner side of the retainer. The spike to be welded is inserted into the sleeve, with one end of the spike contacting the surface of the spiked roller. The welding head performs rotary welding at the contact position to weld the spikes onto the spike roller. The limiting and fixing components are fixedly installed on the upper surface of the base and located at both ends of the boss, and are symmetrically distributed. The two ends of the spike roller are clamped on the limiting and fixing components. The limiting and fixing components are used to drive and fix the spike roller. During driving, the spike roller is rotated, and after rotating to a set angle, the spike roller is fixed, so that the welding components can stably weld the spikes in the set position. The control host is fixedly installed on one side of the base. The control host electrically controls the limiting and fixing components and the welding components, so as to accurately control the position of welding the spikes onto the spike roller according to the set program, so as to weld the spikes into a straight line, spiral, or wave shape, thereby improving the applicability during use.

[0005] Preferably, the limiting and fixing assembly includes a limiting plate with a U-shaped groove and symmetrical fins along the U-shaped groove. The two ends of the spike roller are engaged inside the U-shaped groove, and a movable frame is movably mounted on one side of the limiting plate. Rubber wheels are rotatably mounted on the movable frame, and the four rubber wheels hold the ends of the spike roller tightly. When the spike roller is placed, the movable frame moves away from the U-shaped groove and then moves in the opposite direction, so that the rubber wheels hold the two ends of the spike roller tightly, which facilitates the limiting of the spike roller.

[0006] Preferably, a clamping electric telescopic rod is fixedly installed on one side of the fin, and the symmetrically distributed movable frames can move relative to each other through the clamping electric telescopic rod, which facilitates the movement of the movable frames. A drive motor is fixedly installed on one side of the movable frame, and the output end of the drive motor drives one of the four rubber wheels located at the lower end, which facilitates the use of friction to rotate the spike roller and adjust the welding position.

[0007] Preferably, an L-shaped positioning plate is fixedly installed on one side of the limiting plate at the lower end of the U-shaped groove, and a positioning electric telescopic rod is fixedly installed on one side of the positioning plate. A pressure block is fixedly installed at the telescopic end of the positioning electric telescopic rod, and the pressure blocks at both ends clamp the end of the spike roller. After adjusting the angle, it is convenient to clamp and fix the spike roller, thereby improving the stability during welding.

[0008] Preferably, the welding assembly is equipped with lifting electric telescopic rods fixedly installed at both ends of the retainer to facilitate the adjustment of the welding height and prevent the welded spikes from affecting the movement of the welding assembly. The lower end of the lifting electric telescopic rod is fixedly installed with a mounting base, which is fixedly connected to the moving end of the electric slide rail, so that the electric slide rail can drive the welding assembly to move as a whole.

[0009] Preferably, the sleeve is a T-shaped structure that runs vertically through the shaft, and an airbag ring is fixedly installed at the upper end of the sleeve to straighten the upper end of the spike. An air pump is fixedly installed on one side of the upper end of the retainer, and the air outlet of the air pump is connected to the airbag ring. After the spike is inserted, the airbag ring clamps the upper end of the spike, improving the stability and straightening effect during welding.

[0010] Preferably, the upper ends of both sides of the retainer are hollow structures, and a gas purification box is fixedly installed at the hollow position. The air inlet of the gas purification box is located inside the retainer, and a connecting pipe is fixedly installed between the two gas purification boxes. An air inlet pipe is fixedly installed between the upper end of one of the gas purification boxes and the air inlet of the air pump. During welding, it is convenient to filter and purify the exhaust gas generated during welding and reduce pollution.

[0011] Preferably, an electromagnetic venting valve and a pressure relief valve are fixedly installed on one side of the pipe connecting the air pump and the air bag ring. The electromagnetic venting valve is located near the air bag ring, and the pressure relief valve is located near the air pump, which facilitates the inflation and deflation of the air bag ring. After it is fully filled, the air pump continues to operate to facilitate the treatment of the fumes generated during welding.

[0012] Preferably, the lower end of the sleeve extends to the lower end of the retainer, and a turntable is rotatably mounted inside the retainer on the outside of the sleeve. The welding head is located below the turntable, and the lower end of the welding head is inclined. A servo motor is fixedly mounted on the upper end of the retainer on one side of the sleeve. The servo motor drives the turntable, which facilitates the rotation of the welding head, causing the welding head to reciprocate in a circular motion to perform circumferential welding at the contact point between the spike and the spike roller, thereby improving the welding quality.

[0013] Preferably, the lower end of the retainer is fixedly mounted with a bearing on the outside of the sleeve, the upper end of the turntable is fixedly mounted below the bearing, and teeth are fixedly mounted on the outside of the turntable. A gear disk is fixedly mounted on the output end of the servo motor, and the outside of the gear disk meshes with the teeth.

[0014] The beneficial effects of the present invention are: by using the limiting and fixing component, it is convenient to drive the spike roller to be processed to rotate, and after adjusting the rotation angle, the limiting and fixing is performed so that the welding component can weld the spikes onto the spike roller, thereby improving the stability during welding.

[0015] By inserting spikes one by one into the welding assembly and using a rotating welding head, the spikes are welded one by one onto the spike roller. The rotation angle of the spike roller is adjusted by a limiting and fixing assembly, and the position of the welding assembly is adjusted by an electric slide rail, so as to meet the different welding distribution requirements of the spikes on the spike roller, making it highly applicable.

[0016] During welding, the ends of the spikes are straightened by the airbag ring, which improves the welding quality. At the same time as the airbag ring is inflated, the air pump draws external gas into the gas purification box to help purify the fumes generated during welding and improve the environmental protection effect.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-8As shown, a welding device for a spiked roller includes a base 1, a limiting and fixing component 3, a spiked roller 4, a welding component 5, and a control host 6. The base 1 has a long strip structure, and a boss parallel to the long strip is set in the middle of the upper surface of the base 1. An electric slide rail 2 is symmetrically fixedly installed on the upper surface of the base 1 with the boss. The electric slide rail 2 drives the welding component 5 to move laterally on the base 1, which facilitates the welding of spikes at different positions and improves the flexibility and applicability during welding. The limiting and fixing component 3 is fixedly installed on the upper surface of the base 1 and located at both ends of the boss, and is symmetrically distributed. The two ends of the spiked roller 4 are clamped in the limiting and fixing component 6. On the fixing component 3, the limiting fixing component 3 is used to drive and fix the spike roller 4. During driving, the limiting fixing component 3 rotates the spike roller 4, causing the angle of the spike roller 4 to change. After rotation, it limits the spike roller 4, keeping it stationary and improving stability during spike welding. The two ends of the welding component 5 are fixedly mounted on the moving end of the electric slide rail 2. The welding component 5 includes a gate-shaped retainer 501. When picking up or putting down the spike roller 4, the welding component 5 moves to one end of the base 1 to avoid obstructing the picking up or putting down of the spike roller 4. The upper center of the retainer 501 is located at... A sleeve 502 is fixedly installed to limit the position of the spikes on the spike roller 4. When welding the spikes, the spikes are inserted into the sleeve 502, with one end of the spike inserted to contact the surface of the spike roller 4. The sleeve 502 facilitates the straightening of the spikes to be welded, preventing tilting. During use, the worker only needs to insert the spike into the sleeve 502, requiring no other operations, ensuring production efficiency and quality while reducing the worker's labor intensity. A welding head 503 for welding the spikes to the spike roller 4 is rotatably mounted on the upper inner side of the retainer 501. After the spike is inserted into the sleeve 502, the welding head 503 welds the position where the spike contacts the spike roller 4. During welding, the welding head 503 rotates to form a circumferential welding effect, which improves the welding effect. The control host 6 is fixedly installed on one side of the base 1. The control host 6 electrically controls the limiting and fixing component 3 and the welding component 5, which makes it easy to set the distance of each run of the electric slide rail 2, the angle of rotation of the limiting and fixing component 3 on the spike roller 4, and control the start and stop of the welding component 5 welding the spike onto the spike roller 4, thereby improving the automation effect, reducing manual intervention, and improving the uniformity of processing the spike roller 4.

[0021] The limiting and fixing assembly 3 includes a limiting plate 301 with a U-shaped groove 302 and symmetrical fins 303 along the U-shaped groove 302. The two ends of the spike roller 4 are engaged inside the U-shaped groove 302, facilitating support for both ends of the spike roller 4. A movable frame 304 is movably mounted on one side of the limiting plate 301, and rubber wheels 305 are rotatably mounted on the movable frame 304. The four rubber wheels 305 grip the ends of the spike roller 4, thereby limiting the position of the spike roller 4 and improving stability during spike welding. One side of the fins 303 is fixed... A clamping electric telescopic rod 306 is fixedly installed. The symmetrically distributed movable frames 304 move relative to each other via the clamping electric telescopic rod 306. The clamping electric telescopic rod 306 facilitates control of the distance between the symmetrically distributed movable frames 304. When the spike roller 4 is picked up or put down, the distance between the movable frames 304 increases, making it easier to remove the spike roller 4 from the U-shaped groove 302. When the spike roller 4 is welded, the distance between the movable frames 304 shortens, causing the four rubber wheels 305 to press against the spike roller 4 from all sides, improving the welding process. To ensure stability during welding, a drive motor 307 is fixedly mounted on one side of the movable frame 304. The output of the drive motor 307 drives one of the four rubber wheels 305 located at the lower end. When adjusting the rotation angle of the spike roller 4, the drive motor 307 is turned on, causing the drive motor 307 to drive one of the rubber wheels 305 to rotate. Utilizing the friction between the rubber wheel 305 and the end of the spike roller 4, the spike roller 4 rotates, facilitating the adjustment of the welding position. One side of the limiting plate 301 is located in the U-shaped groove 302. An L-shaped positioning plate 308 is fixedly installed at the lower end of the device. A positioning electric telescopic rod 309 is fixedly installed on one side of the positioning plate 308. A pressure block 3010 is fixedly installed at the telescopic end of the positioning electric telescopic rod 309, and the pressure blocks 3010 at both ends clamp the ends of the spike roller 4. After the rotation angle of the spike roller 4 is adjusted, the positioning electric telescopic rod 309 pushes the pressure block 3010, so that the pressure blocks 3010 on both sides press the ends of the spike roller 4, restricting the rotation of the spike roller 4 and improving the stability during welding.

[0022] In the welding assembly 5, lifting electric telescopic rods 504 are fixedly installed at both ends of the retainer 501. These rods allow for easy adjustment of the height of the retainer 501, preventing the welded spikes from affecting the movement of the welding assembly 5 after welding to the spike roller 4. A mounting base 505 is fixedly installed at the lower end of the lifting electric telescopic rod 504. The mounting base 505 is fixedly connected to the moving end of the electric slide rail 2, allowing the electric slide rail 2 to move the entire welding assembly 5 along the base 1. This facilitates adjustment of the welding position and, in conjunction with the limiting and fixing assembly 3, improves the adaptability of the spike distribution during welding, allowing the welded spikes to be distributed on the spike roller 4 in various patterns such as straight lines, spirals, and waves to meet different needs. The welding process involves a T-shaped sleeve 502 that extends vertically. An air bladder ring 506 is fixedly installed at the upper end of the sleeve 502 to straighten the upper end of the spike. When no spike is inserted, the air bladder ring 506 is de-inflated. After the spike is inserted and its position adjusted, the air bladder ring 506 is inflated. The expansion of the air bladder ring 506 reduces its inner diameter, thus straightening one end of the spike, improving the welding effect and preventing tilting. An air pump 507 is fixedly installed on one side of the upper end of the retainer 501. The air outlet of the air pump 507 is connected to the air bladder ring 506 for easy inflation. Both upper sides of the retainer 501 have a hollow structure and are located in the hollowed-out positions. A gas purification box 508 is fixedly installed. The interior of the gas purification box 508 is filled with materials used to purify the fumes generated during welding (filter cotton, activated carbon, adsorption cotton, molecular sieves, etc.), and the internal filling can be replaced. The air inlet of the gas purification box 508 is located inside the retainer 501, facilitating the extraction of welding fumes into the gas purification box 508 for purification. A connecting pipe 509 is fixedly installed between the two gas purification boxes 508, ensuring a negative pressure state inside both gas purification boxes 508 when the air pump is turned on. An air inlet pipe 5010 is fixedly installed between the upper end of one gas purification box 508 and the air inlet of the air pump 507, facilitating the extraction of air from the interior of the gas purification box 508. The air pump 507... An electromagnetic venting valve 5011 and a pressure relief valve 5012 are fixedly installed on one side of the pipe connected to the airbag ring 506. The electromagnetic venting valve 5011 is located near the airbag ring 506, and the pressure relief valve 5012 is located near the air pump 507. During welding, the air pump 507 is turned on to inflate the inside of the airbag ring 506, thereby straightening the spikes. After the airbag ring 506 is inflated, the air pump 507 continues to be turned on, allowing excess gas to be discharged through the pressure relief valve 5012, thus purifying the fumes generated during welding and reducing environmental pollution. After welding is completed, the air pump 507 is turned off, and the electromagnetic venting valve 5011 is turned on to release air from the inside of the airbag ring 506 to avoid affecting the subsequent insertion of spikes.The lower end of the sleeve 502 extends to the lower end of the retainer 501, and a turntable 5013 is rotatably mounted inside the retainer 501 on the outside of the sleeve 502. A welding head 503 is located below the turntable 5013, and its lower end is inclined. A servo motor 5014 is fixedly mounted on the upper end of the retainer 501 on one side of the sleeve 502, driving the turntable 5013. A bearing 5015 is fixedly mounted on the lower end of the retainer 501 on the outside of the sleeve 502, and the upper end of the turntable 5013 is fixedly mounted on the bearing 5015. Below 015, and with teeth 5016 fixedly mounted on the outer side of the turntable 5013, and a gear disk 5017 fixedly mounted on the output end of the servo motor 5014, the outer side of the gear disk 5017 meshes with the teeth 5016. During welding, the servo motor 5014 is turned on, and the servo motor 5014 drives the turntable 5013 to rotate on the bearing 5015 through the gear disk 5017. After one rotation, the servo motor 5014 is started in reverse, causing the welding head 503 to reciprocate in a circular motion, welding the circumference of the spikes and improving the welding effect.
