Description

Technical Field

[0001] The utility model relates to the technical field of medical isolation gown production equipment, in particular to a sleeve folding welding mechanism for an isolation gown. Background Art

[0002] Chinese patent document CN117465006A, published (announcement) date: 2024.01.30, discloses a dynamic welding molding system and molding method for the isolation gown body disclosed by our company, which discloses a sleeve welding device for welding the sleeves. When welding the sleeves, due to the thin thickness and softness of the clothing material, the weld seam is prone to wrinkles during ultrasonic welding, so the sleeve welding device has been improved.

[0003] Patent application number 202421200477X, filed on May 29, 2024, discloses a welding device for isolation gowns. This device is an improvement on the sleeve welding device. A linear conveyor drives an ultrasonic welding mechanism in linear motion via a movable table. The ultrasonic welding mechanism's welding roller is located on the upper side of the table. When the edge of the garment is placed on the table, a clamping device presses the edge against the table. The linear conveyor then drives the ultrasonic welding mechanism back and forth toward the other end of the table. The welding roller rests against the table and rolls along it, welding the garment edge. This device has the advantage of preventing wrinkles during welding, improving the welding process. However, because the clamping device compresses the garment edge against the table, wrinkles can still form on the upper layer of fabric during welding. To address this issue, researchers have developed further improvements. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0033] Example 1:

[0034] See Figures 1-2, a folding welding mechanism for an isolation gown sleeve, comprising a linear conveying device 20, an ultrasonic welding mechanism 50 and a welding table 60. The linear conveying device 20 loads the ultrasonic welding mechanism 50 to reciprocate, and a welding table 60 is provided on the lower side of the welding roller 51 of the ultrasonic welding mechanism 50. A sliding seat 30 is installed on the slide 21 of the linear conveying device 20, one end of the lower side of the sliding seat 30 is located on the slide 21, and a support 40 is installed on the other end of the cantilevered seat. The ultrasonic welding mechanism 50 is installed on the support 40, and the ultrasonic welding mechanism 50 includes a welding roller 51 and an ultrasonic transducer 54. Both ends of the central axis 52 of the welding roller 51 are respectively installed and connected to the support 40 through bearings, and the central axis 52 is located at an end away from the linear conveying device 20 and is equipped with a passive wheel 53. The central axis 52 is located at an end close to the linear conveying device 20 and is equipped with an ultrasonic transducer 54. A motor 55 is installed on the upper side of the sliding seat 30, and a driving wheel is installed on the output shaft of the motor 55, and the passive wheel 53 is transmission-connected to the driving wheel.

[0035] The linear conveying device 20 adopts a linear module. The linear conveying device 20 is driven by a servo motor 22, thereby driving the sliding seat 30 to move back and forth along the length direction of the linear conveying device 20. At the same time, the motor 55 drives the welding roller 51 to rotate synchronously, thereby driving the welding roller 51 of the ultrasonic welding mechanism 50 to roll on the welding table 60, thereby solving the problem of wrinkles generated when welding the sleeves of the isolation gown.

[0036] During use, the welding portion of the folded isolation gown sleeve is located on the welding platform 60 and is pressed by the welding roller 51 for welding.

[0037] The ultrasonic transducer 54 is a prior art device. The ultrasonic transducer 54 can be fixed to the central axis 52 of the welding roller 51 by threaded connection. The tail of the ultrasonic transducer 54 is equipped with an electric slip ring, and the power cord is connected to the electric slip ring. When the welding roller 51 rotates, the power cord will not be entangled.

[0038] In this embodiment, the support 40 adopts a double-ear support, and bearing mounting holes are respectively provided on the two side walls of the double-ear support. Bearings are installed in the bearing mounting holes, and both ends of the central axis 52 of the welding roller 51 are rotatably connected to the double-ear support through bearings.

[0039] Specifically, the passive wheel 53 and the driving wheel are gears, and the passive wheel 53 and the driving wheel are meshed for transmission; or the passive wheel 53 and the driving wheel are pulleys, and the passive wheel 53 and the driving wheel are driven by a belt; or the passive wheel 53 and the driving wheel are sprockets, and the passive wheel 53 and the driving wheel are driven by a chain.

[0040] Example 2:

[0041] On the basis of embodiment 1, the invention further comprises a base plate 10, on which the linear conveying device 20 and the welding table 60 are mounted. The base plate 10 forms an integral structure.

[0042] Example 3:

[0043] On the basis of Example 2, a linear guide rail 90 is further mounted on the base plate 10, a slider 91 is mounted on the linear guide rail 90, and a sliding seat 30 is supported and mounted on the slider 91. The linear guide rail 90 is arranged parallel to the linear conveying device 20. The linear guide rail 90 and the slider 91 further support the sliding seat 30, thereby improving the stability of the sliding seat 30.

[0044] Example 4:

[0045] In addition to the embodiment 1, 2, or 3, a negative pressure adsorption box 80 is further included. The negative pressure adsorption box 80 is mounted on the side of the welding table 60 away from the linear conveyor 20. The upper side of the negative pressure adsorption box 80 is provided with adsorption holes and a suction pipe opening. The negative pressure adsorption box 80 adsorbs and flattens the fabric, thereby improving the welding effect.

[0046] When in use, the suction pipe mouth of the negative pressure adsorption box 80 is connected to the air inlet of the vortex blower through a pipe. A three-way valve is provided on the pipe. When welding is completed, the three-way valve is switched to connect the air inlet of the vortex blower with the environment, so that the negative pressure adsorption box 80 loses the negative pressure, making it easier to remove the fabric.

[0047] Example 5:

[0048] In accordance with the first, second, third, or fourth embodiments, a clamping device 70 is further included. The clamping device 70 is mounted on a side of the welding table 60 near the linear conveying device 20. The clamping device 70 includes a hinge seat 71, a clamping jaw 72, and a cylinder 73.

When the cylinder 73 is actuated, the side of the clamping jaw 72 near the welding table 60 can abut against the upper side of the welding table 60. Before welding, the clamping device 60 is used to clamp the welded edge of the sleeve, further eliminating wrinkles in the sleeve fabric and improving the welding effect.

[0049] Example 6:

[0050] On the basis of Example 1 or 2 or 3 or 4 or 5, see Figure 2The sliding base 30 includes a fixed base 31 and a lifting base 32. The fixed base 31 is mounted on the sliding base 21. The ultrasonic welding mechanism 50 is mounted on the lifting base 32. A lifting cylinder 33 is installed between the fixed base 31 and the lifting base 32. The lifting cylinder 33 drives the lifting base 32 to rise and fall, thereby driving the ultrasonic welding mechanism 50 and the motor 55 to rise and fall, thereby facilitating the placement of the sleeve fabric on the welding table 60 and compacting the sleeve fabric.

[0051] The working principle or action process of the utility model is as follows:

[0052] During use, the lifting cylinder 33 extends, the lifting seat 32 rises, and the sleeve fabric is placed on the welding table 60. The lifting cylinder 33 then retracts, the lifting seat 32 descends, and the welding roller 51 presses the sleeve fabric on the welding table 60. The linear conveyor 20 is then driven by the servo motor 22, driving the sliding seat 30 to move toward the other end of the linear conveyor 20. When the servo motor 22 is activated, the motor 55 also starts to drive the welding roller 51 to rotate synchronously. The ultrasonic transducer 54 is also activated at the same time, thereby driving the welding roller 51 of the ultrasonic welding mechanism 50 to roll and weld on the welding table 60. After the lifting seat 32 stops moving, the motor 55 also stops synchronously, thereby solving the problem of wrinkles when welding the isolation gown sleeve. After welding is completed, the lifting cylinder 33 extends, the lifting seat 32 rises, and the sleeve fabric is removed.

[0053] After the next sleeve fabric is placed on the welding table 60, the lifting seat 32 descends, and the servo motor 22 and the motor 55 are started, driving the sliding seat 30 to move in the opposite direction for welding. After the lifting seat 32 stops moving, the motor 55 also stops synchronously, and then the lifting cylinder 33 extends, and this is repeated.
