[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] like Figures 1 to 10 As shown, the automatic folding device for garment pieces used in the production line of medical protective clothing of the present invention is located on the upper side of the garment piece cutting table 1 and the garment piece ironing table 10, and is connected to the upper part of the garment piece ironing table 10; the automatic folding device for garment pieces includes a linear drive mechanism, a clamping body 8, a folding stop rod 9 and a lifting mechanism.

[0032] Among them, both ends of the clamping body 8 are respectively connected to the lifting mechanism, which can drive the clamping body 8 to move downward and clamp the symmetrical folding position of the garment piece 2 to be folded, and then drive the clamping body 8 to move upward to cross the folding barrier rod 9; and the lifting mechanism is connected to the linear drive mechanism, which drives the clamping body 8 and the garment piece to be folded 2 to move horizontally along the conveying direction of the production line, folding the single-layer garment piece 2 to be folded into a symmetrical double-layer structure to form a garment piece 11 to be ironed.

[0033] Specifically, if Figure 1 As shown, the linear drive mechanism is a synchronous belt mechanism, including a center seam clamp bracket 4, a transmission shaft 3, a synchronous belt pulley 5 and a synchronous belt 6; a pair of center seam clamp brackets 4 are installed on the left and right sides of the upper end of the garment piece ironing table 10, and the two center seam clamp brackets 4 are connected by a pair of transmission shafts 3, and synchronous belt pulleys 5 are installed at both ends of the transmission shaft 3. The two synchronous belt pulleys 5 on the same side are connected for transmission through the synchronous belt 6, and the outer end of the transmission shaft 3 on the input end side of the center seam clamp bracket 4 is connected to the synchronous belt drive motor 12, and the synchronous belt drive motor 12 is fixed on the center seam clamp bracket 4.

[0034] like Figure 5 As shown, the lifting mechanism includes a vertical cylinder 16 and a mounting frame 7. Both ends of the clamping body 8 are connected to the cylinder rod of a vertical cylinder 16. The vertical cylinder 16 can drive the clamping body 8 to move downward and clamp the symmetrical folding position of the garment piece 2 to be folded, and then drive the clamping body 8 to move upward to cross the folding barrier rod 9; at the same time, the mounting frame 7 of the vertical cylinder 16 is connected to the linear drive mechanism.

[0035] like Figure 4 、 Figure 5 As shown, a bearing seat 15 is provided at each end of the clamp body 8, a vertical cylinder 16 is installed on the upper end of the mounting frame 7, and the cylinder rod of the vertical cylinder 16 passes through the mounting frame 7 and is connected to the bearing seat 15; at the same time, a horizontally extending guide rail is provided on the inner side of the middle seam clamp bracket 4, the mounting frame 7 is slidably connected to the guide rail, and the mounting frame 7 is connected to the synchronous belt 6 through a synchronous belt buckle 14, so that the clamp body 8 is driven to move horizontally by the movement of the synchronous belt 6.

[0036] The ends of the folding stopper 9 are fixedly connected to the center seam clamp bracket 4. The folding stopper 9 is located behind the clamping station of the clamp body 8 and below the guide rail. The function of this rod is to fold the lifted garment piece in half. This device only uses the horizontal and vertical movement of the clamp and a folding rod to achieve the complete folding of large garment pieces, greatly saving the space required for the movement of the mechanism and making the entire production line more compact.

[0037] like Figure 6 As shown in / 8 / 9 / 10, the clamp body 8 includes a left clamp 19, a right clamp 17, a finger-shaped cylinder 18 and a hinge mechanism. The left clamp 19 and the right clamp 17 are rotatably connected by the hinge mechanism. At the same time, a finger-shaped cylinder 18 is provided between the left clamp 19 and the right clamp 17 to drive the relative rotation of the two. The hinge mechanism adopts a design of inner and outer steel pipe sleeves, including an inner core shaft 22 and an outer core shaft 21 that are connected to each other, and the inner core shaft 22 and the outer core shaft 21 have staggered notches. The inner core shaft 22 is connected to the left clamp 19 by screws, and the outer core shaft 21 is connected to the right clamp 17 by screws.

[0038] Among them, spherical gaskets are used in the connection between the finger-shaped cylinder 18 and the left clamp 19 and the right clamp 17 to meet the situation that the axis of the finger-shaped cylinder 18 is not perpendicular to the clamp plane when the clamp is tightened.

[0039] In addition, polyester resin 20 is provided on the inner side of the left clip 19 and the right clip 17. The polyester resin 20 is elastic and can play an anti-slip role, increase the friction between the fabric and the fabric, and increase the reliability and stability in the process of pulling the fabric; it can also reduce the damage caused by the clip to the folded garment piece 2.

[0040] like Figure 5 、 Figure 6 As shown, auxiliary clamping pins 13 are installed in the gap between the garment cutting table 1 and the garment pressing table 10. These pins are horizontally mounted vertical plates, their bottoms fixedly connected to the garment pressing table 10. When the garment cutting table 1 delivers the cut, single-layer garment to be folded to a designated position, the centerline of the symmetrical fold is directly above the auxiliary clamping pins 13. Simultaneously, the timing belt 6 drives the clamping body 8, positioning its jaws directly above the auxiliary clamping pins 13. A vertical cylinder 16 then operates to move the clamping body 8 downward to the designated position. At this point, the finger-shaped cylinders 18 on the clamping body 8 drive the left and right clamping pieces 19 and 17, which are filled with polyester resin 20, to clamp the fabric. The clamping body 8, which holds the fabric, utilizes the auxiliary clamping pins 13 to assist in gripping the fabric. The center of the clamping body's jaws aligns with the pins and presses down on the fabric, ensuring full entry into the clamping body's jaws and stable, reliable grip.

[0041] It should be noted that the linear drive mechanism can also be a linear cylinder or a guide rail slider module, wherein the cylinder rod of the linear cylinder is connected to the mounting frame 7 of the vertical cylinder 16, or the slider of the guide rail slider module is connected to the mounting frame 7 of the vertical cylinder 16. In addition, the lifting mechanism composed of the vertical cylinder 16 and the mounting frame 7 can also be replaced by other lifting devices, such as a scissor fork mechanism, an electric cylinder, a linear slide module, etc.; they can also drive the clamping body 8 to move up and down to complete the clamping and resetting actions.

[0042] The working principle and working process of the automatic folding device for garment parts of a medical protective clothing production line of the present invention will be briefly described below with reference to the accompanying drawings.

[0043] First, the garment cutting table 1 transfers the cut single-layer garment pieces to be folded to the designated position so that the symmetrical folding center line of the garment pieces 2 to be folded is located directly above the auxiliary clamping pins 13; at the same time, the synchronous belt mechanism is reset and the clamping body 8 is moved directly above the auxiliary clamping pins 13 (such as Figure 5 Then, the vertical cylinder 16 drives the clamp body 8 to move downward to the specified position. At this time, the finger-type cylinder 18 on the clamp body 8 drives the left clamp 19 and the right clamp 17 equipped with polyester resin 20 to tighten the fabric (such as Figure 6 ).

[0044] Then, the vertical cylinder 16 connected to the bearing seat 15 drives the clamping body 8 to move upward as a whole, and the upward position passes the folding barrier rod 9. At this time, the synchronous belt drive motor 12 rotates forward to drive the transmission shaft 3 to rotate, and then drives the synchronous belt 6 through the synchronous belt pulley 5. The synchronous belt buckle 14 installed on the synchronous belt 6 also drives the mounting frame 7 to move horizontally.

[0045] At this time, the entire clamp body 8 moves horizontally with the garment pieces 2 to be folded along with the synchronous belt 6. When the single-layer garment piece passes over the folding stop bar 9, the single-layer garment piece is folded into a double-layer garment piece (such as Figure 7 ), and follow the synchronous belt 6 to bring the clothes to the garment ironing platform 10, and after arriving at the designated position.

[0046] Finally, the vertical cylinder 16 drives the clamping body 8 to move downward and move the left clamping piece 19 and the right clamping piece 17 to the garment piece close to the garment piece ironing table 10. At this time, the finger-shaped cylinder 18 drives the clamping piece to release the garment piece, and then the vertical cylinder 16 drives the clamping body 8 to move upward, and then the synchronous belt drive motor 12 reverses, and drives the clamping body 8 to return to its original position in the same way, and continues to clamp the garment piece 2 to be folded delivered from the garment piece cutting table 1, completing a cycle.

[0047] In addition to the above beneficial effects, the present invention has the following advantages over the prior art:

[0048] 1. The present invention mainly focuses on the automation design of the garment folding section of the existing protective clothing production line, aiming to design an efficient garment folding mechanism suitable for the protective clothing production line; it can solve the problem of the difficulty in folding the cut garment panels on the current protective clothing production line. Compared with manual operation, the present invention has the characteristics of high work efficiency, small footprint, ability to match the rhythm of the entire production line, accurate folding, safety and reliability.

[0049] 2. The present invention is primarily mounted on the protective clothing conveyor platform and uses a servo motor to drive the synchronous movement of two timing belts. This ensures coordinated horizontal movement of the fabric clamping fixture, thereby improving the reliability and stability of the horizontal movement of the fabric clamping fixture. It also reduces the number of motors used, making the structure more compact.

[0050] 3. The fabric clamping fixture adopts the thimble-assisted method to clamp the fabric. The center of the fixture mouth is aligned with the thimble and presses down the fabric, so that the fabric fully enters the fixture mouth, making the clamping stable and reliable. In addition, the clamping end of the fixture is installed with a polyester resin clip, which can increase the friction between the clamp and the fabric, and increase the reliability and stability during the fabric lifting process.

[0051] 4. A folding rod is installed behind the clamping station to fold the lifted garment pieces in half. This invention utilizes only the horizontal and vertical movement of the clamp and a folding rod to achieve the complete folding of large garment pieces, significantly saving the space required for mechanical movement and making the entire production line more compact.

[0052] 5. The clamping part of the clamp of the present invention adopts the extension and contraction of the finger-type cylinder to realize the tightening and loosening states. In order to increase the rigidity of the clamp's simply supported beam structure, the design of the inner and outer steel pipes fitting together is adopted, and the clips are installed on the steel pipes in an offset installation. This design can avoid the concentrated distribution of the notches and thus reduce the strength of the steel pipe. The clips on both sides are driven by the finger-type cylinders to drive the inner and outer steel pipes to rotate respectively.

[0053] 6. All movements of the present invention are driven independently. The horizontal movement of the clamp body is driven by a synchronous belt, the vertical movement of the clamp body is driven by a cylinder, and the clamping action is driven by a finger-type cylinder. The simple structure facilitates installation, commissioning, and maintenance.

[0054] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
