Description

Technical Field

[0001] The utility model relates to the field of non-standard automated mechanical equipment, in particular to an automatic metal pipe plugging machine. Background Art

[0002] In modern kitchenware manufacturing, metal mesh frames or baskets are widely used in kitchen appliances, cookware accessories, and other products due to their durability, ventilation, and breathability. To ensure the structural strength of the product, traditional manufacturing methods often use solid metal rods as the outer frame or support rods. However, while this design provides the necessary strength, it also comes with some significant disadvantages. Due to the high density of solid metal rods, using this material results in higher raw material costs. For large-scale kitchenware manufacturers, this not only increases the cost of each product but also reduces overall profit margins. The use of solid metal rods also increases the weight of the product, which not only affects its convenience but also makes transportation and installation inconvenient. For products that need to be moved frequently, an overly heavy design is clearly not the best choice.

[0003] In recent years, new design solutions have emerged in the industry to reduce costs while maintaining product performance. These include using a metal outer tube encased in a metal inner rod to form the outer frame or support rod. This design not only maintains the strength and stability of the metal rod, but also effectively reduces production costs by reducing material usage. Furthermore, the hollow structure helps reduce the overall weight of the product, making it more portable and easier to use.

[0004] However, in the actual production process, this new design has brought a series of new challenges. In the existing technology, all processes are performed manually, including sleeve connection, plugging, welding, and cutting of metal tubes. Among them, when manually performing the plugging operation, due to the slenderness and thin wall of the metal outer tube, it is often difficult to accurately position it, which can easily cause the plug to be misaligned or not fully embedded, and the efficiency is extremely low. In addition, the manual force is relatively small, and even after the metal plug is aligned with the metal tube, it is not easy to press the metal plug into the metal tube, which is time-consuming and labor-intensive. At the same time, manual handling of materials, loading and unloading, and assembly line operations are required, and production efficiency is extremely low.

[0005] The applicant has realized the automation of the entire process of metal pipe sleeve connection, plugging, welding and cutting during research and development. Among them, this application aims to provide an automatic metal pipe plugging machine to solve the problems existing in the prior art. Utility Model Content

[0025] The following examples further illustrate the features of the present invention and other related features to facilitate understanding by those skilled in the art:

[0026] For ease of description and understanding, please refer to the descriptions of the front, back, up, down, left, right, outside, inside and other positional relationships in this case. Figure 2 The orientation shown in .

[0027] like Figures 1 to 6As shown, this case provides an automatic plugging machine for metal pipes, which specifically includes a frame 100 that provides an installation platform and a supporting effect. A conveying mechanism 1 for conveying metal pipes 200 is provided on the frame 100. The conveying mechanism 1 is used to carry and move the metal pipes 200, and convey the metal pipes 200 to the corresponding position of each mechanism, which is responsible for loading and unloading the metal pipes 200, and links the subsequent mechanisms together through the conveying mechanism 1 to achieve efficient linkage. A first clamping mechanism 2, a first blocking mechanism 3, and a first vibration disk feeding mechanism 4 are installed on the frame 100 from left to right. A second vibration disk feeding mechanism 5 with the same structure as the first vibration disk feeding mechanism 4, a second blocking mechanism 6 with the same structure as the first blocking mechanism 3, and a second clamping mechanism 7 with the same structure as the first clamping mechanism 2 are also installed on the frame 100 from left to right. The first clamping mechanism 2 and the second clamping mechanism 7 are respectively located below and above the conveying mechanism 1, and are respectively used to clamp the metal plugs from the corresponding first vibration disk feeding mechanism 4 and the second vibration disk feeding mechanism 5, and transfer them to the corresponding first sealing mechanism 3 and the second sealing mechanism 6. Among them, the first sealing mechanism 3 is used to seal the metal plug clamped by the first clamping mechanism 2 into the lower end of the metal tube 200. The second sealing mechanism 6 is used to seal the metal plug clamped by the second clamping mechanism 7 into the upper end of the metal tube 200, thereby completing the sealing of both ends of the metal plug. In specific implementation, the first vibration disk feeding mechanism 4 and the second vibration disk feeding mechanism 5 can adopt the vibration disk feeding mechanism commonly used in this field, but they need to be adaptively improved according to the structure of the metal plug.

[0028] It should be noted that, in practice, this invention employs multiple sensor switches to detect the presence or absence of an object and its placement, thereby triggering the device's actions or changing its state. This is well known in the art, and a detailed description of each sensor switch is omitted here. In practice, those skilled in the art may, based on common knowledge in the art and in conjunction with the present invention's automatic metal tube threading machine, configure the sensor switches to achieve linkage between the various mechanisms.

[0029] In addition, since the second vibration disk feeding mechanism 5 of this case has the same structure as the first vibration disk feeding mechanism 4, the second blocking mechanism 6 has the same structure as the first blocking mechanism 3, and the second clamping mechanism 7 has the same structure as the first clamping mechanism 2. Therefore, in the description of the specific embodiment of this case, the description of the corresponding structure, function, use and beneficial effects of the second vibration disk feeding mechanism 5, the second blocking mechanism 6 and the second clamping mechanism 7 can refer to the description of the first vibration disk feeding mechanism 4, the first blocking mechanism 3 and the first clamping mechanism 2 respectively, and will not be repeated in this case.

[0030] Reference Figure 1 、 Figure 2 、 Figure 4 As shown, specifically, the conveying mechanism 1 includes two fixed plates 11 symmetrically arranged in an upper and lower direction, and a rolling feeding module 12 rotatably connected between the two fixed plates 11. The fixed plates 11 are two flat plate structures symmetrically arranged in an upper and lower direction, used to support and install the conveying chain 111, the rolling feeding module 12 and other related components. A conveying chain 111 is installed at the upper end of the fixed plate 11, and a plurality of concave first receiving grooves 1111 are equidistantly provided on the conveying chain 111. The equidistantly arranged first receiving grooves 1111 ensure the position consistency of the metal tube 200 on the conveying chain 111, thereby improving the processing accuracy. The concave first receiving grooves 1111 can better fix the metal tube 200, prevent sliding or collision during the conveying process, and reduce product damage.

[0031] The metal tube 200 is placed on the conveying chain 111 through the first receiving grooves 1111 on both sides and follows the forward movement of the conveying chain 111. The rolling loading module 12 is used to transfer the metal tube 200 from the rolling loading module 12 to the first receiving groove 1111 on the conveying chain 111. Through the rolling loading module 12, the metal tube 200 can be loaded quickly and accurately, thereby improving the overall production efficiency. The right end of the conveying chain 111 is connected to a feeding guide rod 112, and the setting of the feeding guide rod 112 guides the feeding of the metal tube 200. The feeding guide rod 112 is located at the right end of the conveying chain 111, that is, Figure 2 The right end shown is the other end away from the rolling feeding module 12. It should be noted that the conveyor chain 111 in this case can use a common conveyor chain 111 in the art, but a first receiving groove 1111 is provided on the conveyor chain 111 to ensure smooth transportation of the metal pipe 200.

[0032] Continue to refer to Figure 1 、 Figure 2 、 Figure 4Specifically, the rolling loading module 12 includes a rotating shaft 121 rotatably connected to two fixed plates 11, a turntable 122 fixedly mounted on the rotating shaft 121 and positioned between the two fixed plates 11, and a first motor 123 connected to one end of the rotating shaft 121 for driving the rotation of the rotating shaft 121. In practice, the rotating shaft 121 is rotatably connected to the two fixed plates 11 via bearings and other devices, providing a rotation center for the turntable 122. The first motor 123 drives the rotating shaft 121, which in turn rotates the turntable 122, thereby positioning the metal tubes 200 in the first storage slot 126 into the second receiving slot 1221. The metal tubes 200 are then transferred to the first receiving slot 1111 on the conveyor chain through the rotation of the turntable 122, achieving automatic loading of the metal tubes 200 and improving production efficiency. To ensure stable transportation of the metal tubes 200, two turntables 122 are provided, each with a plurality of second receiving slots 1221 spaced evenly apart. The second receiving slots 1221 are evenly spaced to ensure the positioning accuracy and stability of the metal tubes 200 during transport. Multiple second receiving slots 1221 can continuously supply metal tubes 200, ensuring the continuity of the production line. A loading guide rod 124 is connected to the left end of the conveyor chain 111. Limiting plates 125 are symmetrically arranged outside the two fixed plates 11. The limiting plates 125 are positioned outside the loading guide rods 124. The left end of the turntable 122 is located between the two loading guide rods 124, and the right end is located between the two conveyor chains 111. The limiting plates 125 and the loading guide rods 124 cooperate to form a first storage slot 126 for accommodating the metal tubes 200. The loading guide rods 124 are used to guide the metal tubes 200 into the second receiving slots 1221 of the turntable 122. The storage slot 126 formed by the limiting plates 125 and the loading guide rods 124 can accommodate more metal tubes 200 simultaneously and ensure that the metal tubes 200 are fixed in position while waiting to be loaded, thereby improving accuracy.

[0033] like Figure 1-Figure 3 、 Figure 5As shown, as a preferred embodiment of this case, further, a first mounting platform 101 and a second mounting platform 102 are slidably connected to the rack 100. The second mounting platform 102 is symmetrically arranged with the first mounting platform 101 and has the same structure. The rack 100 is also provided with a slide rail 103. Two slide rails 103 are symmetrically arranged. The lower ends of the first mounting platform 101 and the second mounting platform 102 are slidably connected to the two slide rails 103 through detachable sliders 104. The sliders 104 are detachable, which facilitates the rapid disassembly and adjustment between the first mounting platform 101 and the second mounting platform 102 and the rack 100. In specific implementation, a locking device is provided between the slider 104 and the slide rail 103 to lock the position of the first mounting platform 101 and the second mounting platform 102 when the equipment is working. Two fixing plates 11 are fixedly mounted on the first mounting platform 101 and the other on the second mounting platform 102. The first mounting platform 101 and the second mounting platform 102 are symmetrically arranged, and then the slider 104 is slidably connected to the slide rail 103 on the frame 100, so that the width of the two fixed plates 11 can be adjusted by sliding the first mounting platform 101 and the second mounting platform 102 on the frame 100. By adjusting the width of the two fixed plates 11, the entire width of the conveying mechanism 1 is adjusted to adapt to metal pipes of different lengths. In order to facilitate the adjustment of the width of the conveying mechanism 1, the other components of the entire metal pipe automatic plugging machine are adjusted to collaboratively realize the original machine function. In this embodiment, the first clamping mechanism 2, the first blocking mechanism 3 and the first vibration disk feeding mechanism 4 are installed on the first mounting platform 101, and the second clamping mechanism 7, the second blocking mechanism 6 and the second vibration disk feeding mechanism 5 are installed on the second mounting platform 102. In this way, all relevant mechanisms can be adaptively adjusted by sliding the first mounting platform 101 and the second mounting platform 102, without the need to adjust each component separately, which simplifies the adjustment process and is flexible and convenient. This modular design makes the equipment easier to maintain and repair, reducing equipment downtime.

[0034] like Figure 1 、 Figure 2 、 Figure 4As shown, a metal tube fixing module 13 is fixedly connected to the fixing plate 11 for fixing the metal tube 200 on the conveyor chain 111. The metal tube fixing module 13 includes a first fixing bracket 131 fixedly mounted on the first mounting platform 101. The first fixing bracket 131 includes a U-shaped bracket 1311 symmetrically connected to the outside of the fixing plate 11 and a first connecting plate 1312 connected to the two U-shaped brackets 1311. A first pressing cylinder 132 is mounted on one of the U-shaped brackets 1311. The first pressing cylinder 132 is set toward the end of the metal tube 200 on the conveyor chain 111. The first pressing cylinders 132 on the first fixing brackets 131 on both sides are symmetrically arranged. In a specific implementation, the first pressing cylinders 132 are set at corresponding positions on the fixing plate 11 between the rolling feeding module 12 and the first blocking mechanism 3 and the second blocking mechanism 6. When the conveyor chain 111 is running, before the metal pipes 200 are transported to the corresponding positions of the first blocking mechanism 3 and the second blocking mechanism 6 for plugging, the first pressing cylinders 132 on both sides work simultaneously, pressing the metal pipes 200 facing each other on the conveyor chain 111 toward the conveyor chain 111, so that the metal pipes 200 are flush and accurately positioned. This ensures that the metal pipes 200 are accurately positioned on the conveyor chain 111 to prevent position deviation from affecting the plugging work of the first blocking mechanism 3 and the second blocking mechanism 6.

[0035] Continue to refer to Figure 1 、 Figure 2 、 Figure 4As shown, the first connecting plate 1312 is suspended above the conveyor chain 111 on this side. The fixed module 13 also includes a second pressing cylinder 133 disposed on the first connecting plate 1312 and a positioning block 134 disposed on the outside of the fixed plate 11. To facilitate the simultaneous compression of multiple metal tubes 200, a pressing plate 1331 is connected to the second pressing cylinder 133, and the pressing plate 1331 is arranged toward the metal tubes 200 on the conveyor chain 111. A strip groove 1112 is provided in the middle of the conveyor chain 111, which divides the first receiving groove 1111 into two halves. When the second pressing cylinder 133 is pressed downward, the pressing plate 1331 is snapped into the strip groove 1112, thereby compressing the multiple metal tubes 200 on the conveyor chain 111, ensuring the accurate position of the metal tubes 200 on the conveyor chain 111 and preventing them from shifting during processing. The positioning block 134 is arranged toward the pressure plate 1331 and is used to block the end of the metal tube 200 close to the positioning block 134. Among them, the upper positioning block 134 is used to block the metal tube 200 pressed by the first blocking mechanism 3 when blocking, and the lower positioning block 134 is used to block the metal tube 200 pressed by the second blocking mechanism 6 when blocking. In specific implementation, when the second clamping cylinder 133 is pressed down, the pressure plate 1331 is stuck in the strip groove 1112 to compress the metal tubes 200 on the conveying chain 111 to facilitate the blocking of the plugging mechanism. The positioning blocks 134 on both sides are used for the first blocking mechanism 3 and the second blocking mechanism 6 to press against the metal tube 200 to prevent the metal tube 200 from falling out from the other end when the blocking action is performed, and at the same time provide a force point to facilitate positioning and blocking. In specific implementation, the positioning block 134 is arranged opposite to the clamping claw 233 and the piston rod 321 after being rotated into place, and the three are on the same horizontal line.

[0036] like Figure 1 、 Figure 2 、 Figure 5 、 Figure 6As shown, the first clamping mechanism 2 includes a second fixed bracket 21, a material receiving platform 22 and a clamping cylinder module 23. The second fixed bracket 21 is fixedly connected to the first mounting platform 101, and the second fixed bracket 21 includes a second connecting plate 211 and a third connecting plate 212 located above the second connecting plate 211. The material receiving platform 22 is connected to the second connecting plate 211, and the material receiving platform 22 is provided with a third receiving groove 221 for accommodating metal plugs. The design of the material receiving platform 22 facilitates the clamping operation of the clamping cylinder module 23 and improves the clamping efficiency. The design of the third receiving groove 221 ensures that the metal plug is accurately positioned on the material receiving platform 22, which is convenient for subsequent clamping operations. The first vibration disk loading mechanism 4 includes a vibration disk 41 and a discharge guide rod 42. In specific implementation, a number of metal plugs are placed in the vibration disk 41, and the vibration disk 41 transports the metal plugs to the discharge guide rod 42 through vibration. The end of the discharge guide rod 42 faces the third receiving groove 221 so that the metal plug in the discharge guide rod 42 is transferred to the third receiving groove 221. The clamping cylinder module 23 is connected to the third connecting plate 212. The clamping cylinder module 23 is used to clamp the material on the third connecting plate 212 for use by the first sealing mechanism 3.

[0037] Continue to refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 As shown, specifically, the clamping cylinder module 23 includes a slide cylinder 231 connected to the third connecting plate 212 and a second motor 232 connected to the lower end of the slide cylinder 231. The slide cylinder 231 is used to drive the second motor 232 and the clamping jaw 233 to move up and down in the vertical direction. The cooperation between the slide cylinder 231 and the second motor 232 ensures high-precision clamping and rotation of the metal plug. The second motor 232 is connected to a clamping jaw 233 that can rotate with the motor shaft. The clamping jaw 233 is used to clamp the metal plug and rotate it. The second motor 232 is used to drive the clamping jaw 233 to rotate and rotate the clamped metal plug to an appropriate angle so that it can be transferred to the first blocking mechanism 3. In specific implementation, the rotation angle of the clamping jaw 233 is ninety degrees, and it rotates toward the inner side of the conveying chain 111 and aligns with the metal pipe 200 at the corresponding position to facilitate the plugging operation.

[0038] Continue to refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6As shown, the first blocking mechanism 3 includes a third fixed bracket 31 fixedly mounted on the first mounting platform 101 and a pull rod cylinder 32 connected to the third fixed bracket 31. The pull rod cylinder 32 includes a piston rod 321 disposed toward the clamping jaw 233. The pull rod cylinder 32 drives the piston rod 321 to extend toward the clamping jaw 233 after it has rotated into position, thereby pushing the metal plug on the clamping jaw 233 into the metal tube 200 at the corresponding position. In specific implementation, in order to more accurately and quickly press the metal plug, a push rod for pressing the metal plug can be provided at the front end of the piston rod 321 or in the clamping jaw 233. The diameter of the push rod should be larger than the diameter of the metal plug to facilitate better contact with the metal plug and accurate insertion.

[0039] The following is a description of the working principle of this case in combination with the full text:

[0040] When the equipment is started, the first vibration plate feeding mechanism 4 and the second vibration plate feeding mechanism 5 are started at the same time, and the vibration plate 41 arranges the metal plugs in order and transports them to the discharge guide rod 42. The end of the discharge guide rod 42 faces the third receiving groove 221, and the metal plugs are sent into the third receiving groove 221 on the receiving platform 22 to prepare.

[0041] The metal tube 200 raw material that needs to be plugged is transferred to the storage slot 126 formed by the limit plate 125 and the feeding guide rod 124 through the automated equipment of the previous process. The first motor 123 drives the rotating shaft 121 to rotate, thereby driving the turntable 122 to rotate, automatically clamping the metal tube 200 in the first storage slot 126 into the second receiving slots 1221 evenly spaced on the turntable 122, and allowing the metal tube 200 to move as the turntable 122 rotates. As the turntable 122 continues to rotate, the metal tube 200 automatically falls from the second receiving slot 1221 on the turntable 122 and is transferred to the first receiving slot 1111 on the conveyor chain 111. The metal tube 200 moves along with the conveyor chain 111. When the metal tube 200 reaches the specified position, the conveyor chain 111 stops running to ensure that the position of the metal tube 200 is fixed. Then the first pressing cylinders 132 on both sides work simultaneously, and press the several metal pipes 200 facing each other on the conveyor chain 111 toward the conveyor chain 111, so that the metal pipes 200 are flush and accurately positioned. The conveyor chain 111 continues to run, and after the metal pipes 200 are conveyed to the corresponding positions of the first blocking mechanism 3 and the second blocking mechanism 6, the conveyor chain 111 stops running. At this time, the second pressing cylinders 133 on both sides work simultaneously, and the metal pipes 200 are pressed against the conveyor chain 111. The slide cylinder 231 of the first clamping mechanism 2 drives the second motor 232 and the clamping claw 233 to descend to the metal plug position on the receiving platform 22. After the clamping claw 233 clamps the metal plug in the third receiving groove 221, it rises and rotates ninety degrees toward the inner side of the conveyor chain 111, aligning with the metal pipe 200 at the corresponding position. Due to the pressure exerted by the positioning block 134, the metal tube 200 is relatively fixed during operation of the first sealing mechanism 3. The pull rod cylinder 32 of the first sealing mechanism 3 drives the piston rod 321 toward the clamping jaw 233. The front end of the piston rod 321 or the push rod in the clamping jaw 233 pushes the metal plug into one end of the metal tube 200, completing the sealing operation. The second clamping mechanism 7 and the second sealing mechanism 6 also operate synchronously, and their principles are similar to those described above for the first clamping mechanism 2 and the first sealing mechanism 3. After the sealing is completed, the conveyor chain 111 continues to operate, conveying the sealed metal tube 200 to the next process or the discharge box via the discharge guide rod 112.
