Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them.

[0047] The present application provides a cavity lifting mechanism and a cloth folding device including the cavity lifting mechanism, which are used for folding and sewing shoulder loops. When folding and sewing shoulder loops, the upper and lower cloth loops need to be folded and buckled before sewing. The present application is mainly used for folding the middle and lower cloth loops of shoulder loops.

[0048] like Figure 1As shown, the cavity lifting mechanism involved in the present application includes a bottom plate 10, a cavity surrounding edge 20 and a cavity lifting driving source 41. A slide groove 11 is provided in the bottom plate 10 and is passed through from top to bottom. The cavity surrounding edge 20 is accommodated in the slide groove 11. The inner periphery of the cavity surrounding edge 20 is formed with a cavity 30 distributed on the upper side of the bottom plate 10, and the bottom of the cavity 30 is closed by the bottom plate 10. In particular, at least one of the bottom plate 10 and the cavity surrounding edge 20 can move up and down, and the cavity lifting driving source 41 is connected to the bottom plate 10 and / or the cavity surrounding edge 20 in a transmission manner, and only drives the bottom plate 10 to move up and down, or only drives the cavity surrounding edge 20 to move up and down, or drives the bottom plate 10 and the cavity surrounding edge 20 to move up and down.

[0049] In the cavity lifting mechanism involved in the present application, the bottom plate 10 and / or the cavity edge 20 are driven to move up and down by the cavity lifting drive source 41, so that the cavity edge 20 can be higher than the bottom plate 10, or the cavity edge 20 is flush with the bottom plate 10, or the cavity edge 20 is lower than the bottom plate 10. When the cavity edge 20 is higher than the bottom plate 10, it is in a folding and shaping state, and the cavity 30 distributed on the bottom plate 10 is effectively formed. After the cloth piece is pressed downward into the cavity 30, the folding edge of the cloth piece can be folded inward into the cavity 30 by the translation of the push plate in the cloth piece folding device toward the cavity 30, completing the folding and shaping of the cloth piece. When the upper end of the cavity edge 20 is flush with the upper surface of the bottom plate 10, or the cavity edge 20 is lower than the bottom plate 10, since the cavity edge 20 is not higher than the bottom plate 10, the cavity edge 20 does not interfere with the material removal operation, which facilitates the material removal after the cloth piece is folded. Therefore, the present application can easily switch between the two states of folding and shaping and material transfer by moving the bottom plate 10 and / or the cavity surround 20 up and down, which can not only complete the folding and shaping of the cloth piece, but also facilitate the material removal after the cloth piece is folded, and effectively solve the interference problem when the shoulder loop cloth piece is folded and transferred. The following is an example of the cavity surround 20 being flush with the bottom plate 10 in the material transfer state.

[0050] In the cavity lifting mechanism involved in the present application, the folding and shaping state and the material shifting state can be switched only by the up and down movement of the bottom plate 10: when the bottom plate 10 moves up, the cavity surrounding edge 20 is flush with the bottom plate 10, and when the bottom plate 10 moves down, the cavity surrounding edge is higher than the bottom plate 10. Alternatively, the folding and shaping state and the material shifting state can be switched only by the up and down movement of the cavity surrounding edge 20: when the cavity surrounding edge 20 moves up, the cavity surrounding edge is higher than the bottom plate 10, and when the cavity surrounding edge 20 moves down, the cavity surrounding edge 20 is flush with the bottom plate 10. Alternatively, the folding and shaping state and the material shifting state can be switched by the up and down movement of the bottom plate 10 and the up and down movement of the cavity surrounding edge 20: when the bottom plate 10 moves down and the cavity surrounding edge 20 moves up, the cavity surrounding edge is higher than the bottom plate 10, and when the bottom plate 10 moves up and the cavity surrounding edge 20 moves down, the cavity surrounding edge 20 is flush with the bottom plate 10. Figure 1 and Figure 2In the illustrated embodiment, the base plate 10 is fixedly arranged, and the cavity surround 20 is installed on the base plate 10 so as to be movable up and down. The cavity lifting drive source 41 is installed on the base plate 10 and is transmission-connected to the cavity surround 20. The cavity lifting drive source 41 only drives the cavity surround 20 to move up and down.

[0051] Furthermore, the installation structure of the cavity surrounding edge 20 is as follows: Figure 1 and Figure 2 As shown, the cavity lifting mechanism also includes a first mounting plate 42 fixed at the bottom of the base plate 10, a lifting connecting plate 43, and a cavity main plate 44 that is movably distributed on the lower side of the base plate 10. The cavity lifting driving source 41 is a cylinder and is fixed to the first mounting plate 42. The upper end of the cylinder piston rod of the cavity lifting driving source 41 is fixedly connected to the lifting connecting plate 43. The cavity main plate 44 is fixed to the upper end of the lifting connecting plate 43. The cavity surrounding edge 20 extends upward from the upper surface of the cavity main plate 44. In this way, when the cylinder piston rod of the cavity lifting driving source 41 extends upward, the lifting connecting plate 43, the cavity main plate 44 and the cavity surrounding edge 20 are driven to move upward, so that the cavity surrounding edge 20 is higher than the base plate 10; when the cylinder piston rod of the cavity lifting driving source 41 retracts downward, the lifting connecting plate 43, the cavity main plate 44 and the cavity surrounding edge 20 are driven to move downward, so that the cavity surrounding edge 20 is flush with the base plate 10.

[0052] Furthermore, if Figure 2 and Figure 3 As shown, an opening slot 421 is provided in the first mounting plate 42, and the opening slot 421 penetrates the first mounting plate 42 left and right along the thickness direction of the first mounting plate 42. The lifting connecting plate 43 has a limiting protrusion 431 at one end facing the first mounting plate 42, and the limiting protrusion 431 can be accommodated in the opening slot 421 in an upward and downward manner. An ascending limiting column 51 and a descending limiting column 52 are installed in the limiting protrusion 431, and the ascending limiting column 51 and the descending limiting column 52 are staggered front and back; an ascending limiting block 53 distributed on the upper side of the limiting protrusion 431 and a descending limiting block 54 distributed on the lower side of the limiting protrusion 431 are fixed on the outer surface of the first mounting plate 42. When the cavity lifting driving source 41 drives the cavity surrounding edge 20 to move upward through the lifting connecting plate 43, the ascending limiting column 51 can abut against the ascending limiting block 53, thereby limiting the ascending height of the cavity surrounding edge 20. When the cavity lifting driving source 41 drives the cavity surrounding edge 20 to move downward through the lifting connecting plate 43 , the descending limit column 52 can abut against the descending limit block 54 , thereby limiting the descending height of the cavity surrounding edge 20 .

[0053] Preferably, the rising limit column 51 and the falling limit column 52 are both screws threadedly connected to the limiting protrusion 431. The upper and lower heights of the rising limit column 51 and the falling limit column 52 can be adjusted by turning the screws, thereby adjusting the rising height and falling height of the cavity surround 20, thereby realizing the adjustable lifting and lowering height of the cavity surround 20 to adapt to the sewing of different types of products.

[0054] In addition, the rising limit block 53 and the falling limit block 54 are staggered in distribution, and a first empty area 55 located above the falling limit column 52 is formed on the outer side of the first mounting plate 42 at the side of the rising limit block 53, and a second empty area 56 located below the rising limit column 51 is formed on the outer side of the first mounting plate 42 at the side of the falling limit block 54 to avoid mutual interference.

[0055] Furthermore, if Figure 1 As shown, the cavity lifting mechanism also includes a pressing assembly, which has a pressing plate 61, which can move up and down and is rotatably mounted on the bottom plate 10. After folding is completed and before taking the material, the pressing plate 61 can press the cloth piece to prevent the folded cloth piece from accidentally spreading.

[0056] The preferred structure of the pressing component is: Figure 1 and Figure 4 As shown, the material pressing assembly includes a second mounting plate 62 fixed to the bottom of the base plate 10, a material pressing lifting driving cylinder 63 fixed to the second mounting plate 62, a material pressing connecting plate 64, and a material pressing rotating driving cylinder 65 fixed to the material pressing connecting plate 64. The lower end of the cylinder piston rod of the material pressing lifting driving cylinder 63 is fixedly connected to the material pressing connecting plate 64, and the material pressing plate 61 is fixed to the upper end of the cylinder piston rod of the material pressing rotating driving cylinder 65. The cylinder piston rod of the material pressing lifting driving cylinder 63 extends downward or retracts upward, and accordingly drives the material pressing plate 61 downward or upward; the material pressing rotating driving cylinder 65 can drive the material pressing plate 61 to rotate to the top of the base plate 10 or to the outside of the base plate 10.

[0057] Furthermore, if Figure 1 As shown, the cavity lifting mechanism further includes an electromagnet 70, which is fixed to the bottom plate 10 and distributed in the cavity 30. When the cloth piece is pressed downward into the cavity 30, the electromagnet 70 is energized to absorb the cloth piece, thereby preventing the cloth piece from deflecting and improving the folding quality of the cloth piece.

[0058] In summary, the working principle of the cavity lifting mechanism with the above structure is as follows:

[0059] 1. In the initial state, if Figure 1As shown, the cylinder piston rod of the cavity lifting drive source 41 is in an upwardly extended state, the rising limit column 51 is in contact with the rising limit block 53, and the cavity edge 20 is higher than the base plate 10; the cylinder piston rod of the press plate lifting drive cylinder 63 is in a downwardly extended state, and the press plate 61 is retracted on the front side of the base plate 10.

[0060] 2. After the cloth pieces are folded, the cylinder piston rod of the cavity lifting drive source 41 is retracted downward until the lowering limit column 52 abuts against the lowering limit block 54 , and the cavity surrounding edge 20 is flush with the bottom plate 10 .

[0061] 3. The cylinder piston rod of the material pressing lifting driving cylinder 63 retracts upward; then, the material pressing rotation driving cylinder 65 is actuated to drive the material pressing plate 61 to rotate 90° toward the bottom plate 10; then, the cylinder piston rod of the material pressing lifting driving cylinder 63 extends downward to drive the material pressing plate 61 to move downward to press the cloth piece on the bottom plate 10; wait for material transfer.

[0062] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0063] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention.
