[0008] The present invention provides a welding device for industrial sewing machine accessories to prevent welding chips from splashing. It has the following beneficial effects:

[0009] 1. This is an industrial sewing machine accessory welding device that prevents welding slag from splashing. It is equipped with an air pump that drives the impeller to rotate through a motor to form a negative pressure to inhale external air. A strong suction field is formed around it through a ventilation pipe and an annular suction plate, which can absorb welding slag generated by welding and prevent the welding slag from splashing into the surrounding environment, thereby avoiding affecting the welding quality and the normal operation of the equipment. The magnetic block on the inner wall of the central circular groove absorbs the magnetic accessories through the magnetic field force and fixes it in the center of the square plate, thereby preventing the accessories from moving at will during subsequent operations. The electric push rod controls the concave push block to move toward the center of the square plate, and the oblique half-screen plate performs preliminary screening on the welding slag falling into the rectangular box, thereby screening out some large-particle welding slag, thereby facilitating the subsequent separation of metal welding slag and welding slag without metal content, thereby reducing the workload of subsequent processing.

[0010] 2. This is an industrial sewing machine accessory welding device that can prevent welding slag from splashing. It is equipped with an anti-splash mechanism. The air pump drives the impeller to rotate through the motor to form negative pressure to inhale external air, and forms a strong suction field around it through the ventilation pipe and the annular suction plate, which can absorb the welding slag generated by welding, prevent the welding slag from splashing into the surrounding environment, and avoid affecting the welding quality and normal operation of the equipment. The arc-shaped ring plate is arranged on the outer side of the annular electric slide rail, which effectively blocks the splashing welding slag and prevents the welding slag from entering the annular electric slide rail, thereby protecting the normal operation of the annular electric slide rail. The annular electric slide rail drives the slider to slide on the annular track through electric energy, driving the scraper to perform a scraping operation along the inner side of the annular suction plate. The scraper can remove the welding slag attached to the inner side of the annular suction plate due to cooling and condensation, thereby ensuring the adsorption effect of the annular suction plate, so that it can continuously and effectively handle the welding slag.

[0011] 3. This is an industrial sewing machine accessory welding device that prevents welding shavings from splashing. It is equipped with a mobile clamping mechanism. The magnetic block on the inner wall of the central circular groove absorbs the magnetic accessory through the magnetic field force and fixes it in the center of the square plate, thereby preventing the accessory from moving randomly during subsequent operations. The electric push rod controls the concave push block to move toward the center of the square plate. The concave push block drives the clamping plate to clamp the accessory, so that the accessory remains stable during the welding process and prevents displacement due to vibration or external force. The buffer spring undergoes elastic deformation when the clamping plate applies pressure to the accessory, generating a reverse elastic force, thereby buffering the clamping plate from exerting pressure on the accessory. The clamping force can effectively prevent the accessories from being damaged due to excessive clamping force. The round rod is sleeved on the outside of the buffer spring to fix the expansion and contraction trajectory of the buffer spring, ensuring that the spring expands and contracts in a specific direction when subjected to force, avoiding spring distortion or deviation, and ensuring the stability and reliability of the buffering effect. The magnetic spring clip is attached to the edge of the accessory, increasing the fixing points and area of ​​the accessory. The scissor arm can be flexibly slid and adjusted according to the size of the accessory, driving the magnetic spring clip to better clamp and fit the accessory, and fixing the accessory from multiple directions, effectively preventing the accessory from deflecting in subsequent operations and improving the stability of accessory fixation.

[0012] 4. The welding device for industrial sewing machine accessories that prevents welding slag from splashing is provided with a chip collecting mechanism. The inclined semi-screen plate preliminarily screens the welding slag falling into the rectangular sleeve box, removing some large-particle welding slag, which facilitates the subsequent separation of metal welding slag and non-metal-content welding slag, reducing the workload of subsequent processing. After the electromagnet is energized, it generates a strong magnetic field to adsorb ferromagnetic metal welding slag, achieving the preliminary separation of metal welding slag and non-metal-content welding slag. The annular slide rail drives the roller to rotate, causing the metal welding slag adsorbed on the surface of the roller to rotate to the rear of the partition block and fall into the corresponding pull-out box after leaving the magnetic field, completing the screening and separation of metal welding slag and non-metal-content welding slag, which is convenient for subsequent further processing and recycling of different types of welding slag.

Detailed implementation manner

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] For the first embodiment, please refer to Figures 1 - 4 , the present invention is a welding device for industrial sewing machine accessories to prevent welding chips from splashing, including a base plate 1. A fixed plate 2 is fixedly connected to the top of the base plate 1. A welder 3 is fixedly connected to one side of the fixed plate 2. An anti-spatter mechanism 4 is fixedly connected to the side of the fixed plate 2 close to the welder 3. A moving clamping mechanism 5 is fixedly connected to one end of the top of the base plate 1 away from the fixed plate 2. A chip collection mechanism 6 is fixedly connected to the top of the base plate 1;

[0025] The splash-proof mechanism 4 includes a connecting rod 41. One end of the connecting rod 41 is fixedly connected with an inclined annular plate 42. One side of the inclined annular plate 42 is fixedly connected with an annular suction plate 43. The inner side of the annular suction plate 43 is fixedly connected with an annular baffle 44. One side of the annular baffle 44 is fixedly connected with an annular electric slide rail 45. The side of the annular electric slide rail 45 away from the annular baffle 44 is fixedly connected with an arc-shaped annular plate 46. The top of the connecting rod 41 is fixedly connected with an air pump 47. The air outlet of the air pump 47 is communicated with an air pipe 48. One side of the annular electric slide rail 45 is fixedly connected with a scraper 49. The end of the connecting rod 41 away from the inclined annular plate 42 is fixedly connected with one side of the fixing plate 2. The end of the air pipe 48 away from the air pump 47 is communicated with the annular suction plate 43. During use, the industrial sewing machine parts are placed in the moving clamping mechanism 5. After clamping, the parts are driven to move in front of the welder 3. The welder 3 performs welding on the parts. The splash-proof mechanism 4 intercepts the welding slag generated by the welder 3 when welding the parts and scrapes it off into the chip collection mechanism 6. The chip collection mechanism 6 filters and screens the welding slag, separates and collects the metal welding slag and other welding slag in the welding slag. When the parts reach the designated position, the welder 3 starts to work. A large amount of welding slag will be generated during the welding process. If these welding slags are not processed in time, it will affect the welding quality and the normal operation of the equipment. In order to process the welding slag generated by welding, the air pump 47 is started. The working principle of the air pump is that the motor drives the impeller to rotate, so that a negative pressure is formed in the pump cavity, thereby sucking in external air. The air pump 47 sucks in air flow through the air pipe 48 and the annular suction plate 43. The annular suction plate 43 makes the air flow form a strong suction field around it. The welding slag generated by welding will be adsorbed to the inner side of the annular suction plate 43 under the action of the suction force. In order to prevent the welding slag from splashing into the annular electric slide rail 45 and affecting its normal operation, an annular baffle 44 is arranged on the outer side of the annular electric slide rail 45. The annular baffle 44 can effectively block the welding slag and play a role in protecting the annular electric slide rail 45. When the welding is over, the air pump 47 is turned off. At this time, without the suction force of the air flow, the welding slag not attached to the inner side of the annular suction plate 43 will slide down along the inner side of the annular suction plate 43 under the action of gravity. However, some welding slag may adhere to the inner side of the annular suction plate 43 due to cooling and condensation. In order to remove these attached welding slags, the annular electric slide rail 45 is started. The annular electric slide rail drives the slider to slide on the annular track through electric energy. The slider is connected with the scraper 49. As the annular electric slide rail 45 operates, the scraper 49 scrapes along the inner side of the annular suction plate 43, scraping off the attached welding slag and making it fall into the rectangular sleeve box 61.

There are multiple scissor arms 5513, and the multiple scissor arms 5513 are distributed on the inner side of the arc-shaped plate 5512;

[0027] The chip collecting mechanism 6 includes a rectangular sleeve 61, the inner wall of the rectangular sleeve 61 is fixedly connected with an oblique half screen plate 62, the inner wall of the rectangular sleeve 61 is fixedly connected with an annular slide rail 63, the side of the annular slide rail 63 away from the rectangular sleeve 61 is fixedly connected with a roller 64, the side of the rectangular sleeve 61 close to the annular slide rail 63 is fixedly connected with an electromagnet 65, the side of the rectangular sleeve 61 close to the annular slide rail 63 is located below the roller 64 and is fixedly connected with a dividing block 66, both sides of the rectangular sleeve 61 are provided with rectangular holes 67, both sides of the dividing block 66 are provided with pull-out boxes 68, the bottom of the rectangular sleeve 61 is fixedly connected to the top of the bottom plate 1, one side of the inner wall of the rectangular sleeve 61 is slidably connected to the pull-out box 68, and a plurality of electromagnets 65 are provided, and the plurality of electromagnets 65 Distributed on one side of the rectangular sleeve 61 close to the annular slide rail 63, when in use, the staff first places the accessory to be welded at the center of the square plate 551. A circular groove 5515 is provided in the center of the square plate 551, and a magnetic block 5516 is fixed on its inner wall. The magnetic accessory will be affected by the magnetic field force, and will be adsorbed and fixed in the center of the square plate 551 to ensure that the accessory will not move at will during subsequent operations. Then, the electric push rod 553 is started, driving the concave push block 554 to move toward the center of the square plate 551. The concave push block 554 is connected to the clamping plate 559. When the clamping plate 559 gradually approaches and touches the accessory, a certain pressure will be applied to the accessory to achieve clamping. In order to prevent the accessory from being damaged due to excessive clamping force, a A buffer spring 558 is arranged. When the clamping plate 559 applies pressure to the accessory, the buffer spring 558 is squeezed, the spring will be elastically deformed, and an elastic force in the opposite direction to the external force is generated, thereby buffering the clamping force of the clamping plate 559 on the accessory. The buffer spring 558 is sleeved on the outside of the round rod 557 to fix the expansion and contraction trajectory of the buffer spring 558, ensuring that the spring expands and contracts in a specific direction when subjected to force to avoid the spring from twisting or deflecting. When the round rod 557 is subjected to the pressure transmitted by the clamping plate 559, it will move in the direction of the circular groove 555. A telescopic spring 556 is arranged inside the circular groove 555, one end of the telescopic spring 556 is connected to the round rod 557, and the other end is connected to the inner wall of the circular groove 555. The function of the telescopic spring 556 is to 57 is used for fixing and buffering, and the clamping force of the clamping plate 559 on the accessory is further adjusted to keep it within a suitable range. At the same time, the magnetic spring piece 5510 will fit the edge of the accessory. The arc-shaped magnetic block 5514 is fixedly connected to one side of the scissor arm 5513. There is a magnetic attraction between the arc-shaped magnetic block 5514 and the magnetic spring piece 5510, so that the two fit closely. The scissor arm 5513 is flexibly adjusted to slide according to the size of the accessory. During the sliding process, the scissor arm 5513 drives the magnetic spring piece 5510 to better clamp and fit the accessory, fix the accessory from multiple directions, and effectively prevent the accessory from shifting in subsequent operations. When the accessory is stably fixed, the motor 53 starts to start, driving the square plate 551 to rotate ninety degrees.It is convenient for the fitting to be welded to the soldering device 3. Subsequently, the linear slide rail 52 is activated. The support plate 51 carries the square plate 551 with the fitting already fixed on it. As the linear slide rail 52 operates, the support plate 51 drives the fitting to move in front of the soldering device 3, preparing for the soldering work. After the welding slag falls into the rectangular sleeve box 61, it will pass through the inclined half sieve plate 62. Some large particles of welding slag on the inclined half sieve plate 62 will be screened out and remain on the inclined half sieve plate 62, while the metal welding slag and some other welding slag passing through the sieve holes will enter the lower area. A roller 64 is arranged below the rectangular sleeve box 61. The left half of the inner side of the roller 64 is distributed with an electromagnet 65. The electromagnet 65 consists of a coil and an iron core. When the coil is energized, according to Ampere's law, a strong magnetic field will be generated around the iron core. The metal welding slag has ferromagnetism and will be adsorbed on the surface of the roller 64 by the magnetism generated by the electromagnet 65. The annular slide rail 63 is activated to drive the roller 64 to rotate. The roller 64 rotates with the metal welding slag attached to its surface. When it rotates to the rear of the dividing block 66, the metal welding slag gets out of the magnetic field range generated by the electromagnet 65 and falls into the pull-out box 68 under the action of gravity. The welding slag without metal content, since it is not affected by the magnetism of the electromagnet 65, will directly fall into the pull-out box 68 on the other side of the dividing block 66, realizing the screening and separation of metal welding slag and welding slag without metal content, which is convenient for further processing and recycling of different types of welding slag in the follow-up.,

[0028] When the present invention is operated and used, the industrial sewing machine fitting is placed in the moving clamping mechanism 5. After clamping, it drives the fitting to move in front of the soldering device 3. The soldering device 3 performs soldering treatment on the fitting. The anti-spatter mechanism 4 intercepts and scrapes off the welding slag generated by the soldering device 3 when soldering the fitting into the chip collection mechanism 6. The chip collection mechanism 6 filters and screens the welding slag, and separately collects the metal welding slag and other welding slag in the welding slag,

[0029] The staff first places the accessories to be welded at the center of the square plate 551. A circular groove 5515 is provided in the center of the square plate 551, and a magnetic block 5516 is fixed on its inner wall. The magnetic accessories will be attracted and fixed in the center of the square plate 551 by the magnetic field force, ensuring that the accessories will not move at will during subsequent operations. Then, the electric push rod 553 is started, driving the concave push block 554 to move toward the center of the square plate 551. The concave push block 554 is connected to the clamping plate 559. When the clamping plate 559 gradually approaches and touches the accessories, it will apply a certain amount of pressure to the accessories to achieve clamping. In order to prevent the accessories from being damaged due to excessive clamping force, a buffer spring 558 is provided. When the clamping plate 559 applies pressure to the accessories, When a force is applied, the buffer spring 558 is squeezed, the spring will undergo elastic deformation, and an elastic force in the opposite direction to the external force is generated, thereby buffering the clamping force of the clamping plate 559 on the accessory. The buffer spring 558 is sleeved on the outside of the round rod 557 to fix the expansion and contraction trajectory of the buffer spring 558, ensuring that the spring expands and contracts in a specific direction when a force is applied, thereby preventing the spring from twisting or deflecting. When the round rod 557 is subjected to the pressure transmitted by the clamping plate 559, it will move in the direction of the circular groove 555. A expansion spring 556 is arranged inside the circular groove 555, one end of the expansion spring 556 is connected to the round rod 557, and the other end is connected to the inner wall of the circular groove 555. The function of the expansion spring 556 is to fix and buffer the round rod 557, and further adjust the clamping plate 559. The clamping force of the accessory is maintained within a suitable range. At the same time, the magnetic spring piece 5510 will fit the edge of the accessory. An arc-shaped magnetic block 5514 is fixedly connected to one side of the scissor arm 5513. There is a magnetic attraction between the arc-shaped magnetic block 5514 and the magnetic spring piece 5510, which makes the two fit tightly. The scissor arm 5513 can be flexibly adjusted to slide according to the size of the accessory. During the sliding process, the scissor arm 5513 drives the magnetic spring piece 5510 to better clamp and fit the accessory, fix the accessory from multiple directions, and effectively prevent the accessory from shifting in subsequent operations. When the accessory is stably fixed, the motor 53 starts to start, driving the square plate 551 to rotate ninety degrees, which is convenient for welding the accessory with the welder 3. Then , the linear slide 52 starts, and the support plate 51 carries the square plate 551 with the accessories fixed on it. As the linear slide 52 runs, the support plate 51 drives the accessories to move to the front of the welder 3 to prepare for the welding work. When the accessories reach the specified position, the welder 3 starts to work. A large amount of welding slag will be generated during the welding process. If these welding slags are not handled in time, they will affect the welding quality and the normal operation of the equipment. In order to deal with the welding slag generated by welding, the air pump 47 is started. The working principle of the air pump is to drive the impeller to rotate through the motor to form a negative pressure in the pump chamber, thereby inhaling external air. The air pump 47 inhales airflow through the vent pipe 48 and the annular suction plate 43. The annular suction plate 43 allows the airflow to form a strong suction field around it.The welding slag generated by welding will be adsorbed to the inner side of the annular suction plate 43 under the action of suction. To prevent the welding slag from splashing into the annular electric slide rail 45 and affecting its normal operation, an annular baffle 44 is provided on the outer side of the annular electric slide rail 45. The annular baffle 44 can effectively block the welding slag and play a role in protecting the annular electric slide rail 45. When the welding is completed, the air pump 47 is turned off. At this time, without the suction of the air flow, the welding slag that is not attached to the inner side of the annular suction plate 43 will slide down along the inner side of the annular suction plate 43 under the action of gravity. However, some welding slag may adhere to the inner side of the annular suction plate 43 due to cooling and condensation. To remove this attached welding slag, the annular electric slide rail 45 is started. The annular electric slide rail drives the slider to slide on the annular track through electric energy. The slider is connected to the scraper 49. As the annular electric slide rail 45 operates, the scraper 49 scrapes along the inner side of the annular suction plate 43 to scrape off the attached welding slag and make it fall into the rectangular sleeve box 61. After the welding slag falls into the rectangular sleeve box 61, it will pass through the inclined half sieve plate 62. Some large-particle welding slag on the inclined half sieve plate 62 will be screened out and remain on the inclined half sieve plate 62, while the metal welding slag passing through the sieve holes and some other welding slag will enter the lower area. A roller 64 is provided below the rectangular sleeve box 61. The left half of the inner side of the roller 64 is distributed with an electromagnet 65. The electromagnet 65 is composed of a coil and an iron core. When the coil is energized, according to Ampere's law, a strong magnetic field will be generated around the iron core. The metal welding slag has ferromagnetism and will be adsorbed on the surface of the roller 64 by the magnetism generated by the electromagnet 65. The annular slide rail 63 is started to drive the roller 64 to rotate. The roller 64 drives the metal welding slag attached to its surface to rotate. When it rotates to the rear of the partition block 66, the metal welding slag gets out of the magnetic field range generated by the electromagnet 65 and falls into the pull-out box 68 under the action of gravity. The welding slag without metal content will directly fall into the pull-out box 68 on the other side of the partition block 66 because it is not affected by the magnetism of the electromagnet 65, realizing the screening and separation of metal welding slag and welding slag without metal content, which is convenient for further processing and recycling of different types of welding slag in the follow-up.
