Description

Technical Field

[0001] This invention relates to the field of welding dust collection technology, specifically to a follow-up local dust collection device for welding torches. Background Technology

[0002] In the field of automated surfacing production of wear-resistant steel plates, the efficient control of welding fumes and the stable operation of welding torches have long been technical challenges. Existing dust collection solutions mostly use fixed suction ports near the workstation, whose dust collection effect is highly dependent on the fume diffusion path. When the welding torch moves with the welding process, the fixed suction ports cannot track the position of the welding torch synchronously, resulting in a sharp drop in fume collection efficiency, which is difficult to meet the environmental protection and cleanliness requirements of dynamic welding scenarios. At the same time, traditional dust collection structures and welding torches lack a linkage and adaptation design. This not only makes it impossible to flexibly adjust the suction power and coverage of the suction ports according to the welding conditions, but also easily limits the operational flexibility of the welding torch due to the fixed position of the dust collection components, further affecting production efficiency and welding quality.

[0003] The existing dust collection devices for welding torches also suffer from insufficient structural adaptability: most dust collection components are rigidly fixed to the welding torch, which cannot be adjusted synchronously with the movement of the welding torch, nor can the size of the dust inlet be dynamically changed according to the amount of smoke and dust in different welding processes. This not only leads to a mismatch between the dust collection effect and the working conditions, but may also interfere with the stable operation of the welding torch during the welding process due to the positional deviation of the dust collection components, and even increase the complexity of welding torch maintenance. It is impossible to take into account the coordinated requirements of dust collection efficiency, welding torch flexibility and operational stability. Summary of the Invention

[0018] 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.

[0019] Please see Figures 1-6 The present invention provides a technical solution: a follow-up local dust removal device for a welding torch, which is disposed on the welding torch 8, comprising: Example 1

[0020] A support mechanism 7 is mounted on the welding torch 8. The support mechanism 7 supports the dust collector housing 5, ensuring airflow can pass through the gap between the support mechanism 7 and the welding torch 8, allowing airflow to adsorb dust. The support mechanism 7 includes a strip plate 75 mounted on the welding torch 8, which connects to the welding torch 8 and supports the dust collector housing 5. A connecting frame 74 is provided on the outer side of the strip plate 75, and the inner side of the connecting frame 74 facilitates airflow... The flow is surging, and the outer side of the connecting frame 74 is sealed by the sealing baffle 76. The outer side of the connecting frame 74 is provided with a snap-fit ​​plate 73, which is used to snap the connecting shaft 72, thereby ensuring that the support wheel 71 can support the inner wall of the dust collector housing 5. The connecting frame 74 is pentagonal in shape, and the outer side of the connecting frame 74 is provided with five sets of snap-fit ​​plates 73. Each set of snap-fit ​​plates 73 consists of two plates, which are arranged in a mirror image. The top of the snap-fit ​​plate 73 is provided with a slot, which is used to snap the connecting shaft 72. The dust collector housing 5 is connected to the support wheel 71, which supports the dust collector housing 5. The inner side of the dust collector housing 5 is provided with a slide rail 52, which is used to limit the support wheel 71 to ensure that the support wheel 71 does not deviate during operation. The slide rail 52 is used to limit the support wheel 71. A sealing baffle 76 is connected to the snap-fit ​​plate 73 and the connecting frame 74. The sealing baffle 76 is used to protect the connection between the snap-fit ​​plate 73 and the connecting shaft 72. The adsorbed dust is easy to stick to the connection between the connecting shaft 72 and the snap-fit ​​plate 73, which can cause the rotation to jam. When the position of the dust collector housing 5 on the welding gun 8 is adjusted, jamming is likely to occur. The sealing baffle 76 can achieve a certain degree of sealing and is used to limit the airflow path. The snap-fit ​​plate 73 is provided with an inclined baffle 77, which is used to separate the airflow and prevent the airflow from carrying dust, which may affect the support wheel 71, thereby helping the support wheel 71 to divert the airflow. The inclined baffle 77 is used to protect the support wheel 71.

[0021] The strip plate 75 in the support mechanism 7 connects to the welding torch 8. The connecting frame 74 on the outside of the strip plate 75 is connected to the connecting shaft 72 by five sets of mirror-opposite snap-fit ​​plates 73. The support wheel 71 connected to the connecting shaft 72 runs along the slide rail 52 on the inner side of the dust collector housing 5, which not only provides stable support for the dust collector housing 5, but also ensures that the dust collector housing 5 can slide smoothly on the welding torch 8. During the dust removal operation, the airflow flows through the gap between the support mechanism 7 and the welding torch 8 to achieve dust adsorption. The sealing baffle 76 on the snap-fit ​​plate 73 and the connecting frame 74 limits the airflow path to optimize the adsorption effect, and on the other hand, prevents dust from adhering to the connection between the connecting shaft 72 and the snap-fit ​​plate 73, preventing the support wheel 71 from jamming. The inclined baffle 77 on the snap-fit ​​plate 73 diverts the airflow and reduces the interference of dust on the support wheel 71. Finally, while ensuring that the dust collector housing 5 is stably adapted and adjusted with the welding torch 8, it not only improves the efficiency of dust collection, but also enhances the smoothness and durability of the device operation. Example 2

[0022] The dust collector housing 5 is mounted on the support mechanism 7. The dust collector housing 5 supports the rest of the structure. The support mechanism 7 allows the dust collector housing 5 to slide on the welding torch 8. The support mechanism 7 is connected to the outside of the mounting plate 1. One end of the dust collector housing 5 is connected to the mounting plate 1. The outside of the mounting plate 1 is connected to the other pushing mechanisms that drive the dust collector housing 5 to move. The mounting plate 1 has mounting holes 11 for easy connection. The inside of the mounting plate 1 is provided with a pushing member 2. The output end of the pushing member 2 is provided with a connecting plate 3. The inside of the connecting plate 3 is connected with at least two traction ropes 31. When the pushing member 2 pushes the connecting plate 3 to drive the traction ropes 31 to move synchronously, it drives the scaling mechanism 6 to open and close, adjusting the opening size of the scaling mechanism 6, thereby adjusting the airflow speed at the inlet of the scaling mechanism 6. The connecting plate 3 is sleeved on the dust collector housing 5. The connecting plate 3 can slide on the dust collector housing 5 by being driven by the pushing member 2. The outside of the dust collector housing 5 is provided with a limiting strip 51 for limiting the connecting plate 3.

[0023] The dust collector housing 5 is mounted on the support mechanism 7, which not only supports the rest of the structure but also allows it to slide on the welding torch 8 with the help of the support mechanism 7. One end of the dust collector housing 5 is connected to the mounting plate 1. The mounting plate 1 is connected to the external pushing mechanism that drives the dust collector housing 5 through the mounting hole 11. The output end of the pusher 2 on its inner side is connected to the connecting plate 3 that is sleeved on the dust collector housing 5. The limiting strip 51 on the outer side of the dust collector housing 5 can limit the connecting plate 3 to prevent it from deviating when sliding. When the pusher 2 drives the connecting plate 3 to slide on the dust collector housing 5, at least two traction ropes 31 connected to the inner side of the connecting plate 3 will move synchronously, thereby driving the scaling mechanism 6 to switch between open and closed states and adjust the opening size, thereby changing the airflow speed at the inlet of the scaling mechanism 6 and achieving flexible adaptation of the suction power. Throughout the process, the mounting hole 11 simplifies the connection operation of the external mechanism, and the limiting strip 51 ensures the smooth sliding of the connecting plate 3. Ultimately, it achieves precise control of the dust collection effect and improves the stability and ease of operation of the device.

[0024] Both the dust collector housing 5 and the scaling mechanism 6 are equipped with adapter frames 46, including the guide mechanism 4. There are two adapter frames 46, one located at the connecting end of the dust collector housing 5 and the other on the outside of the scaling mechanism 6. Each adapter frame 46 includes a support base 41, which supports the support plate 42. The support plates 42 are mirror-opposite to each other on the support base 41, and a rotating shaft 43 passes through all the support plates 42. The adapter frames 46 on the dust collector housing 5 are equipped with guide tubes 44, which are hollow and pass through the housing to guide the traction rope 31. The traction rope 31 is made of [material missing]. The steel cable and guide tube 44 are used to prevent the traction rope 31 from bending when pushing, which would reduce the pushing effect. The adapter frame 46 on the scaling mechanism 6 is connected to the connector 45, which is connected to one end of the traction rope 31. The guide tube 44 is used to adapt to the bending of the traction rope 31. The guide tube 44 can rotate through the connection of the rotating shaft 43. The rotation is used to adapt to the connection of the connector 45. At the same time, the connector 45 can also rotate through the connection of the rotating shaft 43, which can also achieve the effect of adapting to the rotation. The connector 45 is used to connect to the end of the traction rope 31.

[0025] Both the dust collector housing 5 and the scaling mechanism 6 are equipped with two adapter frames 46 included in the guide mechanism 4. These are respectively located at the connecting end of the dust collector housing 5 and the outer side of the scaling mechanism 6. The support seats 41 of the adapter frames 46 are correspondingly located on the dust collector housing 5 and the scaling mechanism 6, supporting the mirror-opposite support plates 42. All support plates 42 are perforated by a rotating shaft 43. During operation, the hollow, through-type guide tube 44 of the adapter frame 46 on the dust collector housing 5 guides the steel cable traction rope 31, preventing bending during the pushing process and thus reducing the pushing effect. Meanwhile, the guide tube 44 can rotate via the pivot 43, and the connector 45 connected to the adapter 46 on the scaling mechanism 6 can also rotate via the pivot 43 while being connected to the end of the traction rope 31. The rotational cooperation of the two can adapt to the connection requirements of the traction rope 31. This design not only ensures the smoothness of the traction rope 31 pushing process and avoids pushing failure caused by bending, but also improves the flexibility of cooperation between the guide mechanism 4, the traction rope 31, and the scaling mechanism 6 through rotational adaptation, thereby helping the scaling mechanism 6 to stably adjust the opening size and effectively enhancing the operational reliability and adaptability of the device.

[0026] A scaling mechanism 6 is located at one end of the dust collector housing 5. Driven by the traction rope 31 and guided by the guiding mechanism 4, the scaling mechanism 6 can change the diameter of the suction port, thereby changing the size of the suction port and thus the suction force. The number of scaling mechanisms 6 and connecting plates 3 is the same. A bearing member 61 is provided at the end of the dust collector housing 5. A collar 62 is sleeved on the bearing member 61 and is located on the adjusting plate 63. The adjusting plate 63 rotates on the bearing member 61 and is in a fan shape. When the adjusting plate 63 rotates inward, the connecting fabric 64 is squeezed and folded, reducing the diameter and increasing the airflow velocity of the suction port. Connecting fabric 64 is provided on both sides of all adjusting plates 63. The material of the connecting fabric 64 is an elastic fiber flame-retardant blended fabric. This material has elastic fireproof properties, so it will not affect the movement of the adjusting plate 63, and in actual use, it will not cause burns from welding slag.

[0027] A scaling mechanism 6 is located at one end of the dust collector housing 5, and its number is consistent with that of the connecting plates 3. Under the drive of the traction rope 31 and the guidance of the guiding mechanism 4, it realizes the opening and closing action, thereby changing the diameter of the suction port and adjusting the suction power. A bearing member 61 is provided at the end of the dust collector housing 5. A collar 62 is sleeved on the bearing member 61 and located on the fan-shaped adjusting plate 63, so that the adjusting plate 63 can rotate freely on the bearing member 61. The inner side of all adjusting plates 63 is provided with a connecting fabric 64 of elastic fiber flame-retardant blend material. When the adjusting plate 63 rotates inward... During rotation, the connecting fabric 64 is compressed and folded, the diameter of the suction port decreases, the airflow velocity increases, and the suction power is correspondingly enhanced. When the adjusting plate 63 rotates outward, the connecting fabric 64 expands, the diameter of the suction port increases, the airflow velocity decreases, and the suction power is correspondingly weakened. During this process, the elastic fiber flame-retardant blended fabric will not hinder the rotation of the adjusting plate 63, and can avoid being burned by welding slag due to its flame-retardant and fire-resistant properties. At the same time, the suction power can be precisely controlled by flexibly adjusting the diameter of the suction port, which effectively improves the smoke and dust collection efficiency under different welding conditions.

[0028] The traction rope 31 inside the connecting plate 3 moves synchronously under the drive of the pusher 2. The guide mechanism 4 on the dust removal shell 5 and the scaling mechanism 6 guides the steel cable traction rope 31 through the guide tube 44 on the adapter frame 46 to prevent the traction rope 31 from bending and reducing the pushing effect. The guide tube 44 and the connector 45 rotate with the rotating shaft 43 to adapt to the movement trajectory of the traction rope 31, ensuring that the power is stably transmitted to the scaling mechanism 6. The traction rope 31 drives the fan-shaped adjustment plate 63 of the scaling mechanism 6 to rotate around the collar 62 on the bearing 61. The elastic fiber flame-retardant blended connecting fabric 64 inside the adjustment plate 63 folds or unfolds with the rotation of the adjustment plate 63, thereby changing the diameter of the dust suction port. When the diameter is reduced, the airflow velocity increases and the suction is enhanced. When the diameter is expanded, the airflow velocity decreases and the suction is weakened. The linkage and cooperation of each component realizes the precise control of the dust suction power, adapting to the dust treatment needs of different welding conditions. At the same time, the flame-retardant elastic properties of the connecting fabric 64 prevent welding slag burns and do not affect the opening and closing action. Example 3

[0029] When a large amount of dust is generated in the welding environment and the dust rises, the device can quickly adapt and coordinate: the external pushing mechanism drives the dust removal shell 5 to move upward along the support wheel 71 and slide rail 52 of the support mechanism 7 through the mounting hole 11 of the mounting plate 1, so that the device can follow the dust as it rises. At the same time, the pushing component 2 drives the connecting plate 3 to slide in the opposite direction, and drives the scaling mechanism 6 to move through the traction rope 31. The fan-shaped adjustment plate 63 rotates outward around the collar 62 on the bearing component 61, the inner connecting fabric 64 stretches, and the diameter of the dust suction port is enlarged to increase the range of dust collection. If it is detected that the dust is about to rise, the device can drive the dust removal shell 5 to move upward in advance to seize the front position of the dust diffusion, and intercept the rising dust in advance with the enlarged dust suction port to avoid the dust diffusion. Example 4

[0030] When performing routine welding operations, the device is adjusted to a precise collection state: the external pushing mechanism drives the dust collector shell 5 to move downward along the support mechanism 7 to fit the welding operation area. At the same time, the pushing component 2 drives the connecting plate 3 to slide forward along the limit strip 51 of the dust collector shell 5. The connecting plate 3 drives the traction rope 31 to move. With the rotational adaptation of the guide tube 44 of the guiding mechanism 4 and the connector 45, the traction rope 31 stably transmits power to the scaling mechanism 6, causing the fan-shaped adjustment plate 63 to rotate inward and the connecting fabric 64 to fold. This reduces the diameter of the dust suction port, increases the airflow velocity, and enhances the suction power, which can promptly absorb and remove the dust generated during welding, suppressing dust from the source. At the same time, the elastic flame-retardant properties of the connecting fabric 64 ensure smooth opening and closing, avoiding burns from welding slag.

[0031] When used in a follow-up local dust removal device for a welding torch, the support mechanism 7 is connected to the welding torch 8 via a strip plate 75. The snap-fit ​​plate 73 on the outer side of its connecting frame 74 is fitted with a support wheel 71 via a connecting shaft 72. The support wheel 71 rolls along the slide rail 52 inside the dust removal housing 5, providing stable support and ensuring smooth sliding of the dust removal housing 5. The snap-fit ​​plate 73 and the sealing baffle 76 on the connecting frame 74 limit the airflow path and prevent dust adhesion that could cause jamming. The inclined baffle 77 diverts airflow to protect the support wheel 71. The mounting plate 1 at one end of the dust removal housing 5 connects to an external pushing mechanism via a mounting hole 11. Its inner pushing component 2 drives the connecting plate 3 to slide along the limiting strip 51, causing the steel cable traction rope 31 to move. The guide mechanism 4 on the dust removal housing 5 and the scaling mechanism 6 guides the traction rope through the guide tube 44 of the adapter frame 46. The guide tube 44 and the connector 45 are rotated and adapted by the rotating shaft 43 to ensure stable power transmission. This, in turn, drives the fan-shaped adjustment plate 63 of the scaling mechanism 6 to rotate around the collar 62 on the bearing 61, causing the inner elastic fiber flame-retardant blended connecting fabric 64 to fold or unfold to adjust the diameter of the dust suction port. During conventional welding, the dust removal shell 5 moves downward to fit the working area, the dust suction port narrows and the suction power is increased to promptly absorb dust. When a large amount of dust rises, the dust removal shell 5 moves upward to follow the dust, the dust suction port expands and the collection range is increased. The entire linkage process not only ensures the smoothness and stability of the device operation, but also achieves precise control of the dust suction power, adapting to different welding conditions and effectively improving the efficiency of dust collection. At the same time, the flame-retardant elastic properties of the connecting fabric 64 prevent welding slag burns, further enhancing the practicality and durability of the device.
