Description

Technical Field

[0001] The utility model relates to an ultrasonic heat-sealing device, in particular to an ultrasonic heat-sealing device for surgical drapes. Background Art

[0002] Surgical drapes are generally made of composite materials, and elastic membranes are a common type among them. The elastic membrane is made of TPE material. On this material, the adhesion of hot melt adhesive or double-sided adhesive is weak, making it difficult to ensure a firm connection with other materials and there is a risk of detachment. Relatively speaking, through heat-sealing technology, the connection between the elastic membrane and other materials not only has superior strength but also higher efficiency.

[0003] The principle of ultrasonic heat-sealing is that the ultrasonic energy is transmitted to the welding area through the action of an ultrasonic concentrator on the heat-sealing strip. The existing ultrasonic heat-sealing devices need to perform heat-sealing on the four sides of the elastic membrane respectively during operation, resulting in low working efficiency. In addition, during heat-sealing, it is difficult to ensure the accuracy of perpendicularity and parallelism of the four sides, thus affecting the aesthetics of the product.

[0021] Preferably, as Figure 1 shown, the working gantry 2 has a portal frame structure, including a horizontal frame plate and vertical frame plates. The working gantry 2 is arranged on the workbench 1 through the vertical frame plates on both sides of it.

[0022] Two pneumatic rods 5 are arranged at intervals on the horizontal frame plate of the working gantry 2. The output ends of the two pneumatic rods 5 respectively drive and connect the longitudinal heat-sealing fixing support 7 and the transverse heat-sealing fixing support 10 located within the area framed by the working gantry 2 in a way of penetrating and connecting the horizontal frame plate. It can be understood that as Figure 1 shown, the main structure of the pneumatic rod 5 is located above the working gantry 2, so as to maximize the area of the double workstations and at the same time make the appearance of the double workstations cleaner and more beautiful.

[0023] The longitudinal heat-sealing fixing support 7 and the transverse heat-sealing fixing support 10 are implemented in a way that their respective extension lines are perpendicular to each other, that is, as Figure 2 shown, the longitudinal heat-sealing fixing support 7 is arranged to extend longitudinally, and the transverse heat-sealing fixing support 10 is arranged to extend transversely. Both the longitudinal heat-sealing fixing support 7 and the transverse heat-sealing fixing support 10 are movably connected to the horizontal frame plate of the working gantry 2 through connecting rods 6; in this embodiment, the number of connecting rods 6 of both the longitudinal heat-sealing fixing support 7 and the transverse heat-sealing fixing support 10 is two. The two connecting rods 6 are respectively on both sides of their respective pneumatic rods 5. And for the stability of the setting, the longitudinal heat-sealing fixing support 7 is formed with ear plates for assembling the two connecting rods 6; specifically, the connecting rods 6 are implemented in a way of penetrating and plugging the horizontal frame plate of the working gantry 2.

[0024] Both ends of the longitudinal heat-sealing fixing support 7 and the transverse heat-sealing fixing support 10 are provided with adjusting grooves 13 extending in the same direction as their respective length directions. In this embodiment, the number of adjusting grooves 13 at one end is two, and the two adjusting grooves 13 are arranged in parallel. The adjusting grooves 13 are long strip-shaped through-bottom grooves.

[0026] It further includes a pedal switch 15 electrically connected to the pneumatic rod 5. It should be noted that the circuit system and its control system applied in this embodiment and the content to be protected by this application are not shown herein for special explanation.

[0027] The working principle of this embodiment is as follows:

[0028] Determine the size that needs to be heat-sealed for the surgical drape product, mark this size on the workbench, and adjust the spacing of the heat-sealing strips according to the size;

[0029] First, loosen the adjusting screws 14 that fasten the first transverse heat-sealing strip 8 and the second transverse heat-sealing strip 9 on the longitudinal heat-sealing fixing support 7, and adjust the first transverse heat-sealing strip 8 and the second transverse heat-sealing strip 9 in their respective adjusting grooves 13 until they correspond to the previous size marks, and then tighten the adjusting screws 14 for fastening;

[0030] Secondly, make corresponding adjustments to the first longitudinal heat-sealing strip 11 and the second longitudinal heat-sealing strip 12 in the same manner as above;

[0031] Finally, place the raw material of the surgical drape on the workbench surface of the workbench 1, step on the pedal switch 15, and the two pneumatic rods 5 respectively drive the longitudinal heat-sealing fixing support 7 and the transverse heat-sealing fixing support 10 to press down, and use the heat-sealing strip for ultrasonic heat-sealing.

[0032] In this way, the ultrasonic heat-sealing device for surgical drapes disclosed by the present utility model can perform heat-sealing operations on both sides of the raw material of the surgical drape at the same time, and the production efficiency is twice that of the traditional heat-sealing device, greatly improving the production efficiency; it can dynamically and correspondingly adjust the heat-sealing spacing, reduce errors while improving the compatibility of the raw material size.
