Description

Technical Field

[0001] The utility model relates to the technical field of tooling processing, in particular to an efficient edge-sewing device for medical tooling processing. Background Art

[0002] Medical tooling is the clothing that medical staff need to wear during work. In order to sew the fabrics connected to the medical tooling tightly together, an edge-sewing device is often used to sew the medical tooling.

[0003] For example, the edge-sewing device for the production of medical protective clothing with the patent number CN219076556U includes a pedestal installed on the horizontal ground, a bracket installed above the pedestal, and a sewing wheel. The sewing wheel is rotationally installed on the bracket along its axis, and the fabric to be sewn is clamped between the sewing wheel and the pedestal. The above document still has deficiencies. When in use, through the mutual cooperation of the cleaning roller and the guiding roller, the edge residue can be driven to move outward relative to the sewn fabric, so that the edge residue is separated from the sewn fabric, thus realizing the automatic removal of the edge residue. Through the aggregate box, the removed edge residue can be collected, and it is easy to centrally process the collected edge residue. Through the positioning roller, the sewn fabric and the edge residue can be guided and positioned, reducing the offset of the fabric during edge-sewing, so that the sewing wheel can sew the fabric stably. However, when using the above device to process and sew the medical tooling, only one side of the medical tooling is guided by the guiding roller, and the medical tooling is prone to offset when being fed under the sewing wheel, and thus the efficient edge-sewing of the medical tooling cannot be achieved. At the same time, when sewing the medical tooling, it is necessary to manually press both sides of the medical tooling to prevent the medical tooling from warping, and the degree of automation is relatively low. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the medical tooling is prone to offset when being fed under the sewing wheel, and to propose an efficient edge-sewing device for medical tooling processing.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design an efficient edge-sewing device for medical tooling processing, including a pedestal and a roller. The roller is rotationally connected to the inside of the pedestal through a bearing. A limiting mechanism is arranged inside the pedestal. A first bracket is fixedly connected above the pedestal. A pressing mechanism is arranged inside the first bracket. A second bracket is fixedly connected to the upper surface of the pedestal. A sewing wheel is installed below the second bracket.

[0007] Preferably, the limiting mechanism includes an electric push rod fixed inside the pedestal. The output end of the electric push rod is fixedly connected with a cross bar, the outer wall of the cross bar is slidably connected with the pedestal, two support rods are rotatably connected above the cross bar through a pin shaft, the end of the support rod is rotatably connected with a slider through a pin shaft, the outer wall of the slider is slidably connected with the frame, the outer wall of the frame is fixedly connected with the pedestal, a ring is fixedly connected above the slider, and the ring is slidably connected with the outer wall of the roller.

[0008] Preferably, the pressing mechanism includes a slide rod. The outer walls of the two slide rods are both slidably connected with the first bracket. The upper ends of the two slide rods are both fixedly connected with a connecting rod. The lower ends of the two slide rods are both fixedly connected with the fourth bracket. A spring is sleeved on the outer wall of the slide rod, and the two ends of the spring are respectively fixedly connected with the first bracket and the fourth bracket. A pressure roller is rotatably connected inside the fourth bracket through a bearing.

[0009] Preferably, a third bracket is fixedly connected to the upper surface of the pedestal. A guide roller and a cleaning roller are rotatably connected inside the third bracket through bearings, and both the guide roller and the cleaning roller are connected to an external power source.

[0010] Preferably, a collection box is fixedly connected to the outer wall of the pedestal.

[0011] For the efficient edge sewing device for medical work clothes processing proposed by the present utility model, the beneficial effects are as follows: Through the cooperation among the electric push rod, the cross bar, the support rods, the slider, the frame and the ring, the electric push rod drives the cross bar to slide, the cross bar drives the two support rods to move, the support rods drive the slider to move, the slider slides inside the frame and drives the ring to move, the ring slides on the outer wall of the roller, and the roller is attached to the edge position of the medical work clothes. When the electric push rod is closed, when the medical work clothes pass by the outer wall of the roller, the ring limits the two sides of the medical work clothes. With the cooperation of the wire guide roller, the medical work clothes are not prone to deviation when being fed under the sewing wheel, and thus the efficient edge sewing of the medical work clothes can be realized.

[0012] Through the cooperation among the sliding rod, the connecting rod, the fourth bracket, the spring and the pressing roller, hold the connecting rod by hand and pull it upward. The connecting rod drives the two sliding rods to move upward. The two sliding rods drive the fourth bracket to move upward and compress the spring. The fourth bracket drives the pressing roller to move upward. Pass the medical work clothes to be edge-sewn through between the pressing roller and the roller from the right side, and make the end of the medical work clothes be under the sewing wheel. Release the connecting rod. Under the elastic action of the spring, the spring drives the fourth bracket to move downward, and then the pressing roller moves downward. The outer walls of both the pressing roller and the roller are attached to the medical work clothes. During the sewing process of the medical work clothes, the pressing roller and the roller squeeze the right side of the medical work clothes, and both the pressing roller and the roller can rotate without affecting the movement of the medical work clothes to the left side. The left side of the medical work clothes is squeezed by the guiding roller. When edge-sewing the medical work clothes, there is no need to manually press both sides of the medical work clothes to prevent the medical work clothes from warping, and the degree of automation is relatively high.
