[0001] The utility model relates to the technical field of medical isolation gown production equipment, in particular to a floating rod mechanism for an automatic production line of isolation gowns. Background Art

[0002] Previously, medical isolation gowns were produced by hand sewing, which had low production efficiency. Therefore, our company developed an automatic production line for isolation gowns to realize the automated production of medical isolation gowns.

[0003] During the automated production of medical isolation gowns, after the gown body and sleeves are welded, they should be transported to the next process section at the same speed. It's difficult to precisely match the front-end feeding speed and the back-end cloth pulling speed. If the front-end feeding speed is slow and the back-end cloth pulling speed is fast, the fabric will be pulled, causing wrinkles along the length, affecting the welding effect of subsequent processes. If the front-end feeding speed is fast and the back-end cloth pulling speed is slow, wrinkles along the width will form due to fabric accumulation. To address this issue, a floating rod mechanism for an automated isolation gown production line was proposed under the second state mentioned above. Utility Model Content

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. 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.

[0029] Example 1:

[0030] See Figure 1 A floating rod mechanism for an automatic production line for isolation gowns includes a push rod device 10. A push plate 20 is mounted at the telescopic end of the push rod device 10. At least two telescopic rods 30 are slidably mounted on the push plate 20. A floating rod 40 is mounted on the end of the telescopic rod 30 away from the push rod device 10. A spring 50 is mounted on the telescopic rod 30 between the push plate 20 and the floating rod 40. A limit member 31 is mounted on the telescopic rod 30 on the side of the push plate 20 away from the floating rod 40. Under conditions where the front feeding speed is high and the rear cloth pulling speed is slow, the floating rod mechanism tensions the cloth, thereby eliminating the problems of cloth accumulation and wrinkles.

[0031] When in use, the push rod device 10 is installed longitudinally, the telescopic end of the push rod device 10 faces downward, the push plate 20 is arranged horizontally, the telescopic rod 30 is arranged longitudinally, and the float rod 40 is arranged horizontally. The push rod device 10 pushes the float rod 40 downward, and at the same time, the float rod 40 can move elastically up and down under the action of the telescopic rod 30 and the spring 50, thereby eliminating the problems of cloth accumulation and wrinkles caused by speed mismatch through the float rod 40.

[0032] In this embodiment, the limiting member 31 is used to limit the telescopic rod 30 to prevent the telescopic rod 30 from falling off.

[0033] Furthermore, a guide sleeve 21 is installed on the push plate 20 at a position corresponding to the telescopic rod 30 , and the telescopic rod 30 slides through the guide sleeve 21 , thereby improving the flexibility and stability of the telescopic rod 30 in moving up and down.

[0034] Specifically, a mounting hole is provided on the push plate 20 , and the guide sleeve 21 is installed in the mounting hole and is connected and fixed to the push plate 20 by bolts.

[0035] Example 2:

[0036] On the basis of Example 1, support seats 42 are respectively installed at both ends of the floating rod 40, and the two support seats 42 are connected and fixed to the support plate 41, and the telescopic rod 30 is connected and fixed to the support plate 41.

[0037] In one of the schemes, a bearing is installed on the support base 42, and the floating rod 40 is connected to the bearing. Through such a structure, the floating rod 40 can rotate, reducing the friction between the cloth.

[0038] Specifically, a bearing mounting hole is provided on the support seat 42, and a bearing is mounted in the bearing mounting hole. Both ends of the floating rod 40 are respectively interference fit with the inner hole of the bearing.

[0039] In another embodiment, the floating rod 40 is fixedly connected to the support base 42, or the floating rod 40 and the support base 42 are interlaced. A sleeve 43 is mounted on the floating rod 40 via a bearing. This structure allows the sleeve 43 to rotate, reducing friction with the fabric. In this embodiment, the floating rod 40 and the sleeve 43 can be connected using a non-powered roller.

[0040] Example 4:

[0041] To facilitate adjustment of the spring force of the spring 50 while simultaneously limiting the position of the telescopic rod 30, in one embodiment, the limiting member 31 is a shaft retaining spring. The telescopic rod 30 is provided with a plurality of annular grooves spaced axially apart, and the shaft retaining springs are installed in the annular grooves. By installing the shaft retaining springs in the annular grooves at different positions, the spring force of the spring 50 can be adjusted.

[0042] In another embodiment, the stopper 31 is a nut, and the telescopic rod 30 is provided with an external thread. The nut is screwed onto the telescopic rod 30. By rotating the nut, the position of the nut is adjusted, thereby adjusting the elastic force of the spring 50. Of course, to ensure the stability of the nut after adjustment, two nuts are screwed onto each telescopic rod 30 and tightened together to prevent the nut from rotating due to vibration.

[0043] Example 5:

[0044] Based on Example 1, the push rod device 10 comprises a linear module 11. A connecting seat 13 is mounted on the slider 12 of the linear module 11. A guide seat 15 is mounted on the end of the linear module 11 near the push plate 20. One end of the push rod 14 is fixedly mounted to the connecting seat 13, while the other end slides through the guide seat 15 before being connected and fixed to the push plate 20. The use of the linear module 11 in the push rod device 10 facilitates adjustment of the downward extension distance of the float rod 40.

[0045] The linear module 11 is conventional technology and can be customized and purchased commercially. In this embodiment, the linear module 11 includes a built-in servo motor. The guide base 15 is a U-shaped structure that is screwed onto the linear module 11. The guide base 15 has a through hole at a position corresponding to the push rod 14, through which the push rod 14 slides.

[0046] Furthermore, in order to improve the working stability of the floating rod 40 , a plurality of linear modules 11 are provided.

[0047] exist Figure 1 In the figure, two linear modules 11 are provided, and a right-angle reducer 16 is installed at the end of each linear module 11 away from the push plate 20. The output shaft of the right-angle reducer 16 is connected to the screw inside the linear module 11. The input shafts of adjacent right-angle reducers 16 are connected via a transmission rod 17. The output shaft of the motor 18 is connected to the input shaft of the outermost right-angle reducer 16. With this structure, a single motor 18 can drive the synchronous movement of the two linear modules 11, reducing the number of motors and simplifying control.

[0048] Specifically, the right-angle reducer 16 is conventional, with its input and output shafts arranged at right angles. The ends of the transmission rod 17 are connected to the input shaft of the right-angle reducer 16 via couplings. The motor 18 can be fixed to the right-angle reducer 16 or mounted on a production line frame, driven by a drive shaft or synchronous belt. In this embodiment, the motor 18 is a stepper motor or servo motor.

[0049] Of course, in addition to the linear module 11, the push rod device 10 can also use a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0050] The working principle or action process of the utility model is as follows:

[0051] Under the working condition that the feeding speed at the front end is fast and the cloth pulling speed at the rear end is slow, by controlling the rotation of the motor 18, the downward movement distance of the slider 12 of the linear module 11 is controlled, so that the push rod 14 moves downward by one end distance, and the push plate 20 moves downward by one end distance, so that the float rod 40 moves downward by one end distance. At the same time, the float rod 40 can move elastically up and down under the action of the telescopic rod 30 and the spring 50, so that the problem of cloth accumulation and wrinkles caused by speed mismatch is eliminated through the float rod 40.
