Description

Technical Field

[0001] The invention relates to the technical field of folding equipment for producing underwear, and in particular to a novel full-automatic underwear folding machine. Background Art

[0002] After the garments are produced and processed, they need to be folded and packed for the convenience of transportation and subsequent sales profit. Although underwear, as a close-fitting garment, does not have the complex production process of outerwear and trousers, it also needs to be folded and packed for the convenience of packaging and to attract consumers through unique packaging. At present, the underwear production line is all operated manually to fold the finished underwear, and the packaging and bundling are reclassified as another process. The process is complicated and cumbersome, which increases labor costs.

[0003] The Chinese patent application number "2021225192063" discloses "a flipping and folding device suitable for an automated production line for underwear, comprising a mounting frame (1), characterized in that: a first threaded rod (2) is rotatably connected to the top inner wall of the mounting frame (1), a transmission mechanism (3) is arranged on one side of the first threaded rod (2), a threaded sleeve (13) is threadedly connected to the outer wall of the first threaded rod (2), a transverse plate (14) slidably connected to the inner wall of the mounting frame (1) is fixedly connected to the bottom end of the threaded sleeve (13), symmetrically distributed support rods (15) are fixedly connected to the bottom of the transverse plate (14), two groups of support rods (15) are fixedly connected to the bottom ends of a pressing plate (16), a placement table (17) fixedly connected to the inner wall of one side of the mounting frame (1) is arranged below the pressing plate (16), and the placement table (17) is fixedly connected to the inner wall of one side of the mounting frame (1). ) is fixedly connected to one side of the mounting frame (1), and a folding plate (19) is rotatably connected inside the first hinge block (18), and one side of the bottom of the folding plate (19) is in contact with a limit plate (20) fixedly connected to the inner wall of one side of the mounting frame (1). "This technical solution drives the screw-nut device through a second motor to drive the folding plate to rotate, and the folding plate flips and folds the underwear, and the folded underwear is flattened and arranged by the pressing plate, but there are still the following defects: the folding mechanism is only a folding plate hinged on the placement table, and the screw-nut device has a long stroke and is slow to fold. The underwear is made of flexible material, and it is very easy to cause the underwear to slip and stack irregularly during the folding process of the folding plate, and the folding work cannot be completed well. Secondly, there is only one folding, and then flattening and arranging, which cannot be effectively combined with other production processes, and the degree of automation is low.

[0004] The Chinese patent application number "2021225192063" discloses "a first conveyor belt (2) and a second conveyor belt (3) are respectively fixedly installed, a transfer pressing assembly (4) is fixedly installed on one side of the processing frame (1), and a folding assembly (5) is fixedly installed on one end of the top of the second conveyor belt (3); the folding assembly (5) includes two symmetrical pillars (51) and a first motor (52), and a support seat (53) is observed inside the two pillars (51), and a first folding plate (54) is fixedly installed in the middle of the top of the support seat (53) The first folding plate (54) is hinged with a second folding plate (55) and a third folding plate (56) on both sides thereof; a fourth folding plate (57) is hingedly connected to the front side of the first folding plate (54) and located between the second folding plate (55) and the third folding plate (56); a first hydraulic rod (58), a second hydraulic rod (59) and a third hydraulic rod (510) are fixedly installed at the upper end of the support seat (53) and located at the bottom of the second folding plate (55), the third folding plate (56) and the fourth folding plate (57); the transfer pressing assembly (4) includes a support frame (41) and a second motor (412), two symmetrical supports (42) are fixedly installed on one side of the interior of the support frame (41), a screw rod (43) is passed through the interior of the two supports (42), a wire drum (45) and a second pulley (414) are respectively sleeved on the outside of the screw rod (43) from top to bottom, a third conveyor belt (49) is fixedly installed on one side of the wire drum (45), a first pulley (413) is sleeved on the power driving end of the second motor (412), and the first pulley (413) is connected to the second pulley (414) through a belt (415). ) forms a rotating connection structure. This technical solution uses a hydraulic rod to push the first folding plate, the second folding plate, the third folding plate and the fourth folding plate hinged on the first folding plate to automatically fold the clothing in multiple directions, which speeds up the folding efficiency to a certain extent. However, there is a lack of a clamping and fixing device. The four folding plates are folded in sequence. For clothing made of flexible materials, the folding process will cause the clothing to be pushed out of the predetermined position, resulting in a high folding error, affecting the folding efficiency, and underwear such as underwear still needs to be manually bundled and packaged after being folded and transported to the next process through the conveying end, which does not effectively reduce labor costs.
