[0032] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0033] refer to Figures 1 - 5 As shown, the utility model discloses an automatic folding and pressing mechanism, comprising a pressing upper die 1 and a pressing lower die 2 arranged opposite to each other, and a plurality of folding and pressing devices 3 arranged around the pressing lower die 2;

[0034] The pressing upper die 1 is driven by a cylinder, a hydraulic cylinder, a mechanical arm or other driving parts of the pressing equipment, thereby realizing a lifting movement relative to the pressing lower die 2;

[0035] The side surface of the pressing lower mold 2 is used for placing the side surface fabric a, and the upper surface thereof is used for placing the end surface fabric b;

[0036] The hemming and pressing device 3 includes a first driving member 31 and a second driving member 32 which are arranged up and down and output linear reciprocating motion in the horizontal direction, and a pressing plate 33 and a pressing block 34 which are respectively arranged at the output ends of the first driving member 31 and the second driving member 32; there is a height difference between the lower surface of the pressing plate 33 and the upper surface of the lower pressing die 2, which is used to fold and press the fabric towards the upper surface of the lower pressing die 2 by the pressing plate 33; the pressing block 34 is arranged opposite to the side surface of the lower pressing die 2, and is provided with a pressing surface 341 matching the side surface of the lower pressing die 2.

[0037] Through the above solution, referring to Figure 6 , after the worker puts the side fabric a on the side surface of the lower pressing die 2 and the end face fabric b on the upper surface of the lower pressing die 2, the subsequent actions are all performed by mechanical automation. Mainly, the first driving member 31 and the second driving member 32 respectively drive the pressing plate 33 and the pressing block 34 to move towards the side fabric a. The pressing block 34 pushes the side fabric a against the side surface of the lower pressing die 2 to achieve fixation. The pressing plate 33 presses down and folds the part of the side fabric a that exceeds the end face fabric b through the space provided by the reserved height difference, so that this part of the fabric is tightly fitted to the edge of the end face fabric b. Then the pressing plate 33 retreats to make way for the descending upper pressing die 1 to achieve hot pressing and sealing of the fabric, completing the automatic hemming and pressing process; the utility model only requires the worker to feed the material, and has a high degree of automation, which can achieve the purposes of reducing labor intensity, improving production efficiency and product qualification rate.

[0038] The following shows the specific embodiments of the present utility model.

[0039] In this embodiment, both the first driving member 31 and the second driving member 32 are cylinders; in addition, they can also be hydraulic cylinders, or similar driving members that can output linear reciprocating motion.

[0040] Furthermore, the output ends of the first driving member 31 and the second driving member 32 are respectively detachably installed with a first mounting block 35 and a second mounting block 36, and the pressing plate 33 and the pressing block 34 are respectively fixed relative to the first mounting block 35 and the second mounting block 36, which is convenient for replacing different pressing plates 33 and pressing blocks 34.

[0041] When the pressing plate 33 retreats to make way, it keeps pressing on the hem position of the side fabric a to prevent the pressed fabric from warping and affecting the hot pressing and sealing. That is to say, when the pressing plate 33 retreats, it only needs to make way for the upper pressing die 1 to contact the fabric, and there is no need to completely retreat to a state separated from the fabric.

[0042] Referring to Figure 3 , when the hemming and pressing device 3 is opposite to the edge position of the lower pressing die 2, the pressing surface 341 of the pressing block 34 is a concave surface matching the edge of the lower pressing die 2.

[0043] Furthermore, the pressing plate 33 is provided with a clearance notch 331 matching the edge of the pressing lower die 2 .

[0044] See also Figure 4 When the folding and pressing device 3 is in a planar position relative to the pressing lower die 2, the pressing surface 341' of the pressing block 34' is a plane, and the end surface of the pressing plate 33' is also a plane.

[0045] The above-mentioned pressing lower die 2 includes a frame 21 arranged below the pressing upper die 1 for sleeve-mounting the side fabric a, and a lifting assembly 22 arranged in the frame 21; the frame 21 is provided with a first through hole 211; the lifting assembly 22 includes a lifting plate 221 movably fitted in the first through hole 211, and a third driving member 222 for driving the lifting plate 221 to perform lifting and lowering movements. By providing the lifting assembly 22, after the hot-pressing sealing of the fabric is completed, the fabric can be lifted upward so as to be separated from the frame 21, which is convenient for workers to unload materials and improves production efficiency.

[0046] Furthermore, a movable plate 223 is provided at the output end of the third driving member 222, and a plurality of support rods 224 are vertically connected between the movable plate 223 and the lifting plate 221. The power of the third driving member 222 can be transmitted to the lifting plate 221 more stably and evenly through the movable plate 223 and the support rods 224, so as to support the lifting plate 221 whose area is much larger than the output end of the third driving member 222.

[0047] At the same time, the utility model also includes a support frame 4 for supporting the skeleton 21. The support frame 4 and the skeleton 21 are detachably installed by means of snap connections, threaded connections, etc., so as to facilitate the replacement of different skeletons 21; the support frame 4 is provided with a second through hole 41 for giving way to the lifting component 22.

[0048] The utility model further comprises a height-adjustable mounting platform 5 for mounting the edge folding and pressing device 3 , so as to meet the production requirements of products of different specifications and realize the adjustment of the height of the edge folding and pressing device 3 .

[0049] Furthermore, the mounting platform 5 is supported by a plurality of telescopic adjustment rods 6 to achieve its height adjustment function.

[0050] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
