Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a lifting type smoke extraction device for a sewing machine. Background Art

[0002] The fume extraction device is a device that uses negative pressure to extract the fume generated during the material processing and draw it away from the processing table. When in use, it quickly extracts the fume generated by the table processing, thereby maintaining the visibility and cleanliness of the processing table, while effectively preventing the air near the processing table from being contaminated by the fume generated during the processing, thereby ensuring the health of the processing operators.

[0003] In the textile field, in order to cut and sew fabrics in large quantities, sewing machines with laser cutting equipment are often used to process the fabrics. The fabric is placed on a module, and the module moves as the input program controls the fabric. The fabric is fed into the laser cutting equipment for cutting and then sewing. In order to avoid a large amount of harmful smoke during laser cutting, a smoke extraction device is often installed at the bottom of the processing table. It can effectively extract the smoke generated by laser cutting, reduce the discomfort of the processing operator, and avoid smoke blocking and affecting the laser intensity.

[0004] Although the above-mentioned existing technology can solve the corresponding technical problems, it still has certain defects: when the existing smoke extraction device is used on a laser cutting sewing machine, the smoke extraction device is always attached to the bottom of the processing table corresponding to the laser cutting device. Although it can effectively extract smoke, after the laser cutting is completed, when the fabric on the module needs to be sewn, the module will continue to move and will collide with the smoke extraction device, which will make it difficult for the module to continue moving and need to bypass the smoke extraction device, thereby making the processing table of the entire equipment too large, and since it takes extra time for the module to bypass the smoke extraction device, the processing efficiency of the sewing machine is reduced. Utility Model Content

[0005] The purpose of the utility model is to provide a lifting type fume extraction device for a sewing machine, which prevents obstruction of module movement, reduces the size of the sewing machine, and has high processing efficiency, in response to the defects and shortcomings of the existing technology.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a lifting type smoke extraction device for a sewing machine, comprising an exhaust pipe and a force-bearing plate arranged on the outer wall of the exhaust pipe, a thrust cylinder fixed to the sewing machine is provided below the force-bearing plate, when the sewing machine performs laser cutting, the thrust cylinder generates an upward thrust to push the force-bearing plate, so that the force-bearing plate carries the exhaust pipe close to the laser cutting part of the module to extract the smoke, after the laser cutting, the thrust cylinder retracts and pulls the force-bearing plate back, so that the exhaust pipe descends and does not hinder the continued movement of the module, the upper surface of the thrust cylinder is also fixed with a first guide column that penetrates the force-bearing plate and is slidably connected to the force-bearing plate, the force-bearing plate is located at a relative position to the first guide column and is also penetrated and slidably connected, the bottom of the second guide column is provided with a fixed chassis for being fixedly connected to the sewing machine, the second guide column and the top of the first guide column are provided with a connecting plate for being fixedly connected to the sewing machine, and a penetrating slot is provided through the connecting plate.

[0007] A further improvement is that a sealing ring is further provided on the outer wall of the top end of the exhaust pipe.

[0008] A further improvement is that the second guide post and the first guide post are both penetrated and arranged on the force-bearing plate on the side away from the sewing machine module.

[0009] After adopting the above technical solution, the beneficial effect of the utility model is as follows: the utility model can move the exhaust pipe upward to extract the smoke when the sewing machine is performing laser cutting, and lower it after the cutting is completed, thereby avoiding obstruction of the moving path of the bottom of the sewing machine module, making the movement range of the sewing machine module larger, and there is no need to take a detour when sewing after the laser cutting is completed, which can not only reduce the size of the overall sewing machine, but also effectively improve the processing efficiency of the sewing machine.

[0013] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0014] See Figure 1-2 As shown, the technical solution adopted in this specific embodiment is: a lifting type smoke extraction device for a sewing machine, comprising an exhaust pipe 1 and a force disk 2 arranged on the outer wall of the exhaust pipe 1, a thrust cylinder 6 fixed to the sewing machine is provided below the force disk 2, when the sewing machine is performing laser cutting, the thrust cylinder 6 generates an upward thrust to push up the force disk 2, so that the force disk 2 brings the exhaust pipe 1 close to the laser cutting part of the module to extract the smoke, after the laser cutting, the thrust cylinder 6 retracts and pulls back the force disk 2, so that the exhaust pipe 1 descends and does not hinder the module from continuing to move, when in use, the thrust cylinder 6 is connected to the sewing machine, and the exhaust pipe 1 is aligned with the laser welding position, and then the exhaust pipe 1 is removed from the sewing machine. The external negative pressure fan at the bottom of the air pipe 1, when the sewing machine is performing laser cutting, the thrust cylinder 6 generates an upward thrust to push the force plate 2 upward, so that the force plate 2 brings the exhaust pipe 1 close to the laser cutting part of the module, and the negative pressure fan generates negative pressure to extract the smoke from the exhaust pipe 1. After laser cutting, the thrust cylinder 6 retracts and pulls the force plate 2 back, thereby synchronously driving the exhaust pipe 1 to move downward, so that a gap is formed between the exhaust pipe 1 and the lower table of the sewing machine, thereby allowing the moving module of the sewing machine to pass smoothly without being obstructed. When sewing is performed after laser cutting, the module does not need to take a detour, which can not only reduce the size of the overall sewing machine, but also effectively improve the processing efficiency of the sewing machine.

[0015] The upper surface of the thrust cylinder 6 is also fixed with a first guide column 3 that penetrates the force-bearing disc 2 and is slidably connected to the force-bearing disc 2, which is conducive to guiding the force-bearing disc 2, thereby making its movement trajectory more controllable, thereby making the exhaust pipe 1 better aligned with the laser cutting position, so as to achieve a better smoke extraction effect;

[0016] The force-bearing disc 2 is located at a position opposite to the first guide post 3 and is also penetrated and slidably connected to a second guide post 8. The bottom of the second guide post 8 is provided with a fixed chassis 9 for fixed connection to the sewing machine, which is conducive to further improving the accuracy of the moving trajectory of the force-bearing disc 2 and enhancing the smoke extraction effect.

[0017] A connecting plate 4 for fixedly connecting to the sewing machine is provided at the top of the second guide post 8 and the first guide post 3. A through slot 5 is provided through the connecting plate 4, which is conducive to making the connection between the first guide post 3 and the second guide post 8 more secure and avoiding shaking during operation. At the same time, the through slot 5 prevents the normal movement of the exhaust pipe 1 from being obstructed;

[0018] The outer wall of the top of the exhaust pipe 1 is also provided with a sealing ring 7, which is conducive to enhancing the sealing effect of the top of the exhaust pipe 1 and preventing smoke from leaking during the exhaust process;

[0019] The second guide column 8 and the first guide column 3 are both penetrated and set on the force plate 2 on the side away from the sewing machine module, which is conducive to maximizing the movement range of the module and reducing the influence of the first guide column 3 and the second guide column 8 on the movement of the bottom of the module.

[0020] The working principle of the present utility model: When the present utility model is used, the thrust cylinder 6 is connected to the sewing machine, and the exhaust pipe 1 is aligned with the laser welding position, and then the external negative pressure fan is blown from the bottom end of the exhaust pipe 1. When the sewing machine performs laser cutting, the thrust cylinder 6 generates an upward thrust to push the force plate 2, so that the force plate 2 brings the exhaust pipe 1 close to the laser cutting part of the module, and the negative pressure fan generates negative pressure to extract the smoke from the exhaust pipe 1. After laser cutting, the thrust cylinder 6 retracts and pulls back the force plate 2, and then synchronously drives the exhaust pipe 1 to move downward, so that a gap is generated between the exhaust pipe 1 and the lower table of the sewing machine, thereby allowing the moving module of the sewing machine to pass smoothly without being hindered. When sewing is performed after laser cutting, the module does not need to take a detour, which can not only reduce the size of the overall sewing machine, but also effectively improve the processing efficiency of the sewing machine.
