Technical Field
[0001] This utility model relates to the field of auxiliary equipment technology for tube making machines, and in particular to a material conveying device for tube making machines. Background Technology
[0002] Stainless steel pipe making machines are mainly used to produce various stainless steel pipes, such as pipes for stair railings, security doors and windows, and guardrails. They can also produce various automotive exhaust pipes, heat exchanger pipes, fluid pipes, and food processing pipes. During pipe making, stainless steel strips are fed into the machine and formed into stainless steel pipes through forming and welding. When the stainless steel strip is fed into the pipe making machine, it needs to pass through an uncoiler to uncoil the rolled steel strip, and then pass through a leveling machine to eliminate longitudinal bending and transverse warping before entering the pipe making machine. To ensure the stability of steel strip conveying, a feeding device (conveying device) is needed to guide the steel coil into the leveling machine in real time. However, most current feeding devices use rigid rollers distributed vertically to convey the steel strip. During conveying, the contact area between the rollers and the steel strip is small, resulting in low friction and weak traction, making slippage easy and causing poor conveying stability. Furthermore, the function is limited, and when there are attached metal debris on the steel strip, it can easily damage the surface, leading to defects in the produced stainless steel pipes. Therefore, a feeding device that provides stable conveying and cleans the surface of the steel strip is needed to convey steel strip material to the pipe-making machine. Utility Model Content
[0003] To overcome the technical defects of the existing technology, this utility model provides a material conveying device for a tube making machine, which can stably convey steel strips, avoid slippage, and clean the surface of the steel strips during conveying.
[0004] The technical solution adopted by this utility model is: a material conveying device for a tube-making machine, including a frame, the frame being symmetrically distributed from left to right, with two air rollers rotatably mounted vertically between the paired frame bodies, each air roller having a gear fixedly mounted at one end of its rotating shaft, the two air rollers being linked by the gear meshing, a drive motor fixedly mounted on the outer side of the frame body, and the output end of the drive motor being fixedly connected to the rotating shaft on the upper air roller, a side plate fixedly mounted on one side of the frame body, the end of the side plate having a U-shaped structure, and a cleaning component for scraping and cleaning the upper and lower surfaces of the steel strip being rotatably mounted between the side plates, in use... One end of the steel strip to be conveyed passes through the cleaning component and extends between the upper and lower distributed air rollers. The air rollers are inflated, causing them to press the steel strip tightly. When the drive motor drives the upper air roller to rotate, the lower air roller rotates synchronously through the gears. The upper and lower distributed air rollers traction and convey the steel strip. During conveying, the deformation of the air rollers creates more friction between them and the steel strip, improving the stability of the steel strip conveying. During conveying, the cleaning component scrapes and cleans the upper and lower surfaces of the steel strip, preventing residual metal debris from affecting subsequent pipe production and the quality of the finished pipe.
[0005] Preferably, a rotary joint is fixedly installed at the end of the rotating shaft of the air roller, and an air inflator is fixedly installed between the upper and lower rotary joints. The air inflator is connected to the interior of the air roller through the rotary joint. Through the air inflator, air can be easily injected into the interior of the air roller to adjust the hardness of the air roller, so that the air roller can transport the steel strip.
[0006] Preferably, the lower end of the frame has an L-shaped structure, and the lower end of the frame is provided with a fixing hole for fixed connection with the ground, so as to facilitate fixing the frame to the ground and fix the technical solution.
[0007] Preferably, the cleaning component includes a rotating shaft, which is rotatably mounted on the side plate. The rotating shaft consists of two shafts distributed vertically. A connecting square rod is fixedly installed at the middle position of the rotating shaft. An adsorption rod is inserted into one side of the connecting square rod, and an arc-shaped rubber scraper is fixedly installed on the other side of the adsorption rod. When the steel belt passes through the cleaning component, one side of the vertically distributed rubber scraper contacts the upper and lower surfaces of the steel belt, respectively, and the rubber scraper cleans the surface of the steel belt.
[0008] Preferably, the connecting rod is made of magnetic metal and the adsorption rod is made of magnetic material. The adsorption rod and the connecting rod are magnetically attracted to each other, thereby improving the connection stability and ease of disconnection between the adsorption rod and the connecting rod.
[0009] Preferably, a square insertion slot is provided on one side of the connecting square rod, and an insertion plate that matches the insertion slot is fixedly installed on one side of the adsorption rod. The insertion plate is inserted into the insertion slot. After the adsorption rod is installed, the insertion plate is limited by the insertion slot, thereby preventing the adsorption rod from detaching from the connecting square rod.
[0010] Preferably, each end of the rotating shaft is fixedly equipped with an L-shaped lever, and a spring is fixedly installed between the upper and lower distributed levers. Due to the elastic force of the spring, the levers are subjected to opposite thrusts, which causes the connecting square rod to rotate on the side plate along the rotating shaft. When the rubber scraper passes the steel strip, the rubber scraper adheres to the surface of the steel strip.
[0011] Preferably, the connecting rod is inclined, and the rubber scrapers distributed vertically form a V-shaped structure. Both ends of one side of the connecting rod are fixedly installed with handles. When replacing the rubber scrapers, pressing the handles rotates the insertion slots on the connecting rod to a horizontal position, which facilitates the replacement of the adsorption rod and the rubber scrapers.
[0012] The beneficial effects of this utility model are as follows: Two inflatable rollers distributed vertically clamp the steel strip during transport. During clamping, deformation occurs at the contact point between the inflatable roller and the steel strip, increasing the contact area and friction. Consequently, when the drive motor rotates the inflatable rollers, the steel strip is transported stably. Furthermore, the rubber scraper in the cleaning assembly facilitates the scraping off metal debris adhering to the steel strip. A spring ensures elastic compression between the rubber scraper and the steel strip, improving the adhesion and facilitating cleaning. Attached Figure Description

Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings:
[0021] like Figures 1-6 As shown, this embodiment provides a material conveying device for a tube-making machine, including a frame 1. The frame 1 is symmetrically distributed from left to right. Two air rollers 2 are rotatably mounted vertically between the paired frame 1s. A gear 3 is fixedly mounted on one end of the rotating shaft of the air roller 2. The two air rollers 2 are linked by meshing gear 3. A drive motor 4 is fixedly mounted on the outer side of the frame 1, and the output end of the drive motor 4 is fixedly connected to the rotating shaft on the upper air roller 2. A side plate 5 is fixedly mounted on one side of the frame 1. The end of the side plate 5 has a U-shaped structure, and a cleaning component 6 for scraping and cleaning the upper and lower surfaces of the steel strip is rotatably mounted between the side plates 5. In use, this technical solution is installed in a set position through the frame 1, and one end of the steel strip to be conveyed passes through the cleaning component 6 and extends... The air rollers 2, distributed vertically, are inflated to press the steel strip together. After pressing, the contact area between the air rollers 2 and the steel strip deforms, increasing the contact area. When the drive motor 4 rotates the upper air roller 2, the lower air roller 2 rotates synchronously through the gear 3. The air rollers 2, distributed vertically, traction and convey the steel strip. During conveying, the deformation of the air rollers 2 increases the friction between them and the steel strip, improving the stability of the conveying and preventing slippage. During conveying, the movement of the steel strip allows the cleaning component 6 to scrape and clean the upper and lower surfaces of the steel strip, preventing metal debris from remaining on the surface and affecting subsequent pipe production and the quality of the finished pipe.
[0022] As a technical optimization solution of this utility model, specifically as follows: Figure 2 and Figure 4As shown, a rotary joint 7 is fixedly installed at the end of the rotating shaft of the air roller 2, and an air inflator 8 is fixedly installed between the upper and lower rotary joints 7. The air inflator 8 is connected to the interior of the air roller 2 through the rotary joint 7. Through the air inflator 8, air can be easily injected into the interior of the air roller 2 to adjust the hardness of the air roller 2, so that the air roller 2 can convey the steel strip. The rotary joint 7 also prevents the air inflator 8 from affecting the rotation of the air roller 2. The lower end of the frame 1 has an L-shaped structure, and the lower end of the frame 1 has a fixing hole for fixed connection with the ground. The frame 1 is connected to the ground through the fixing hole by external expansion bolts, so as to fix the frame 1 on the ground and fix the technical solution.
[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 5 and Figure 6As shown, the cleaning component 6 includes a rotating shaft 601, which is rotatably mounted on the side plate 5. There are two rotating shafts 601 arranged vertically. A connecting square rod 602 is fixedly installed in the middle of the rotating shaft 601. An adsorption rod 603 is inserted into one side of the connecting square rod 602, and an arc-shaped rubber scraper 604 is fixedly installed on the other side of the adsorption rod 603. When the steel belt passes through the cleaning component 6, one side of the vertically arranged rubber scraper 604 contacts the upper and lower surfaces of the steel belt, respectively. Therefore, when the steel belt is pulled and moved by the air roller 2, the rubber scraper 604 scrapes and cleans the surface of the steel belt, preventing metal debris from adhering. The adsorption rod 603 and connecting square rod 602 facilitate the replacement of the rubber scraper 604 after it becomes severely worn, improving cleaning stability. The connecting square rod 602 is made of magnetic metal, and the adsorption rod 603 is made of magnet material. The adsorption rod 603 and connecting square rod 602 are magnetically attracted to each other, improving the connection stability and ease of disconnection, and allowing for quick and easy replacement of the rubber scraper 604. A square insertion slot 605 is provided on one side of the connecting square rod 602, and an insertion plate 60 that matches the insertion slot 605 is fixedly installed on one side of the adsorption rod 603. 6. The insertion plate 606 is inserted into the insertion slot 605. After the adsorption rod 603 is installed, when the rubber scraper 604 contacts the steel strip, the insertion plate 606 is limited by the insertion slot 605, thereby preventing the adsorption rod 603 from separating from the connecting square rod 602 and improving the stability of the connection. L-shaped levers 607 are fixedly installed at the ends of the rotating shaft 601, and springs 608 are fixedly installed between the upper and lower levers 607. Through the springs 608, the levers 607 experience opposite thrusts, causing the connecting square rod 602 to rotate along the rotating shaft 601 on the side plate 5, thus causing the rubber scraper... The rubber scrapers 604 are pressed together. When the rubber scrapers 604 pass over the steel strip, they adhere to the surface of the steel strip, making it easier to scrape off the metal debris attached to the surface of the steel strip. The connecting square rod 602 is in an inclined state, and the rubber scrapers 604 distributed vertically form a V-shaped structure. Both ends of one side of the connecting square rod 602 are fixedly installed with handles 609. When replacing the rubber scrapers 604, pressing the handles 609 causes the connecting square rod 602 to rotate along the rotating shaft 601, rotating the insertion slot 605 on the connecting square rod 602 to a horizontal position, which facilitates the replacement of the adsorption rod 603 and the rubber scrapers 604, making the operation convenient.
