[0002] In the technical field of folding and sewing cloth pieces, it is common to put cloth pieces into a cavity and then fold them, so that the cloth pieces can be folded into a shape that can be sewn. For example: in the folding and sewing process of shoulder loops, the cloth piece is first put into the cavity, and then the push plate is translated toward the cavity to fold the folded edge of the cloth piece into the cavity, thereby folding the cloth piece into the shape of a shoulder loop, and finally the folded cloth piece is sewn. At present, the depth of the cavity is generally 3-4mm. When the cloth piece is pressed into the cavity, the folded edge of the cloth piece will be bent 90°, and the outer end of the folded edge of the cloth piece will be almost flush with the surface of the cavity, that is, the cloth piece collapses as a whole in the cavity. When the push plate is subsequently translated toward the cavity, the push plate can hardly act on the folded edge of the cloth piece, making it difficult to fold the cloth piece into place.

[0040] The present application provides a fabric sheet collapse prevention component and a fabric sheet folding device including the fabric sheet collapse prevention component, which are used for folding and sewing shoulder loops. When folding and sewing shoulder loops, the upper and lower fabric sheets need to be folded and buckled before sewing. The present application is mainly used for folding the lower fabric sheet of the shoulder loop, and is particularly suitable for folding the straight folding edges on the left and right sides of the lower fabric sheet.
[0041] like Figure 1As shown, the anti-cloth collapse assembly involved in the utility model comprises a fixed bottom plate 10, a cavity surround 20 installed on the bottom plate 10, a cavity 30 formed on the inner periphery of the cavity surround 20, and a telescopic component installed on the bottom plate 10 and capable of stretching up and down, the opening of the cavity 30 faces upward, the bottom of the cavity 30 is closed by the bottom plate 10, and the telescopic component is placed in the cavity 30. When folding and sewing the shoulder loop, the lower piece of cloth constituting the shoulder loop is placed in the cavity 30, and the cloth is pressed downward into the cavity 30, and the telescopic component in the cavity 30 acts on the cloth in the cavity 30. Based on the property that the telescopic component can be extended and retracted up and down, the telescopic component applies a force toward the surface of the cavity 30 to the cloth piece pressed into the cavity 30, that is, the telescopic component applies an upward force to the cloth piece in the cavity 30, thereby pushing the cloth piece upward for a certain distance, so that the outer end of the folded edge of the cloth piece exceeds the surface of the cavity 30, that is, the upper end of the folded edge of the cloth piece is exposed upward from the cavity 30, and the folded edge of the cloth piece in this state is easily folded into the cavity 30 by the subsequent push plate. Afterwards, when the push plate in the cloth piece folding device translates toward the cavity 30, the push plate can reliably contact the folded edge of the cloth piece and fold the folded edge of the cloth piece inward into the cavity 30. Therefore, the present application uses the telescopic component to make the cloth piece pressed into the cavity 30 in a state that is easy to be folded, avoids the folded edge of the cloth piece collapsing in the cavity 30 without being exposed in the cavity 30, reliably ensures the contact and cooperation between the push plate and the folded edge of the cloth piece, and finally ensures the reliability and accuracy of the subsequent folding action.
[0042] In the anti-cloth sheet collapse assembly involved in the present application, the telescopic component can have multiple embodiments.
[0043] Telescopic component embodiment 1: The telescopic component is a sponge, which is detachably mounted on the upper surface of the base plate 10 and placed in the cavity 30. The sponge is preferably fixed in the cavity 30 by gluing. When the cloth piece is pressed downward into the cavity 30, the elasticity of the sponge can push the cloth piece upward for a certain distance. When the push plate in the cloth piece folding device folds the folded edge of the cloth piece, the push plate will contact the sponge, and the sponge needs to be replaced frequently. The sponge is fixed by bonding, which is convenient for replacement.
[0044] Telescopic component embodiment 2: Figures 2 to 4 As shown, the telescopic component is a cloth piece blocking block 41 mounted on the bottom plate 10 in a movable manner. When the cloth piece is pressed downward into the mold cavity 30, the cloth piece blocking block 41 moves upward to push the cloth piece upward for a certain distance. The telescopic component adopts a movable cloth piece blocking block 41, which is a preferred embodiment of the telescopic component in the present application, and can reliably push the cloth piece upward from the mold cavity 30.
[0045] Furthermore, the installation structure of the cloth blocking block 41 is preferably: Figure 3 and Figure 4As shown, the anti-cloth collapse assembly also includes a first mounting plate 42, a lifting seat 43 movably mounted on the first mounting plate 42, and a blocking driving source 44 mounted on the first mounting plate 42. The first mounting plate 42 is fixed to the bottom plate 10 or the cavity surrounding edge 20. The blocking driving source 44 is in transmission connection with the lifting seat 43, and the lower end of the cloth piece blocking block 41 is fixed to the lifting seat 43 by screws. In this embodiment, the first mounting plate 42 is fixed to the cavity surrounding edge 20. When the blocking driving source 44 drives the lifting seat 43 to move up or down, the lifting seat 43 drives the cloth piece blocking block 41 to move up or down together.
[0046] Preferably, if Figure 3 and Figure 4 As shown, the anti-cloth sheet collapse assembly also includes a transmission connection block 45, and the blocking drive source 44 is a cylinder. The upper end of the cylinder piston rod of the blocking drive source 44 is fixedly connected to the transmission connection block 45. At the same time, the transmission connection block 45 is also fixedly connected to the lower end of the lifting seat 43 by screws; in this way, when the cylinder piston rod of the blocking drive source 44 is extended and retracted up and down, the transmission connection block 45 and the lifting seat 43 are driven to move up or down at the same time, and the cloth sheet blocking block 41 is also driven to move up or down. The anti-cloth sheet collapse assembly also includes a linear guide assembly 46 extending up and down, and the linear guide assembly 46 is connected between the lifting seat 43 and the first mounting plate 42, which plays a good guiding role in the up and down movement of the lifting seat 43.
[0047] Furthermore, if Figure 1 As shown, the front end of the cavity 30 is a pointed head 31; there are two cloth piece blocking blocks 41, which are symmetrically distributed on the left and right sides of the pointed head 31. In particular, the inner circumference of the cavity perimeter 20 is provided with a vertically penetrating slide 21 at the pointed head 31 of the cavity 30, and the cloth piece blocking block 41 can be accommodated in the slide 21 so as to move up and down. The folding edge of the cloth piece at the pointed head 31 is an inclined folding edge, and the cloth piece blocking block 41 pushes the cloth piece upward at the front end of the cloth piece, so as to facilitate the folding of the two straight folding edges of the cloth piece. Preferably, the cloth piece blocking block 41 is a metal part, which increases the wear resistance of the cloth piece blocking block 41, so that the cloth piece blocking block 41 has a longer service life.
[0048] Furthermore, if Figure 1 As shown, the cavity edge 20 is installed on the bottom plate 10 so as to be movable up and down. The bottom plate 10 is provided with an edge slot 11 for accommodating the cavity edge 20. The edge slot 11 passes through the bottom plate 10 up and down, so that the cavity edge 20 is a liftable structure. During the folding operation, the cavity edge 20 is in an ascending state, emerging upward from the bottom plate 10, thereby forming a cavity 30 located above the bottom plate 10; after the cloth piece is folded, the cavity edge 20 descends to a state flush with the upper surface of the bottom plate 10, so as to facilitate the removal of the folded cloth piece and facilitate material removal.
[0049] The mounting structure of the cavity surrounding edge 20 is preferably: Figure 1 and Figure 2 As shown, the anti-cloth sheet collapse assembly also includes a second mounting plate 51 fixed to the base plate 10, a cavity lifting cylinder 52 fixed to the second mounting plate 51, and a cavity main board 53 that can move up and down; the upper end of the cylinder piston rod of the cavity lifting cylinder 52 is connected to the cavity main board 53, and the two can be directly fixedly connected or fixedly connected through other plate components; the cavity main board 53 is distributed on the lower side of the base plate 10 and can move up and down; the cavity surround 20 is integrally formed on the upper surface of the cavity main board 53, and the cavity surround 20 protrudes and extends upward from the upper surface of the cavity main board 53 toward the base plate 10. In this way, when the cylinder piston rod of the cavity lifting cylinder 52 extends upward, the cavity main plate 53 is driven to move upward, and the cavity surround 20 is driven to extend upward from the surround groove 11 of the base plate 10; when the cylinder piston rod of the cavity lifting cylinder 52 retracts downward, the cavity main plate 53 is driven to move downward, and the cavity surround 20 is driven to be flush with the base plate 10.
[0050] Furthermore, if Figure 1 As shown, the anti-cloth collapse assembly also includes an electromagnet 60, which is fixed to the bottom plate 10 and distributed in the cavity 30. When the cloth is pressed downward into the cavity 30, the electromagnet 60 is energized to absorb the cloth, preventing the cloth from deflecting and improving the folding quality of the cloth.
[0051] In summary, taking the anti-cloth collapse assembly configured with the cloth block 41 as an example, the working principle of the anti-cloth collapse assembly is as follows:
[0052] 1. In the initial state, the cylinder piston rod of the blocking drive source 44 is in a downward retracted state, and the cylinder piston rod of the cavity lifting cylinder 52 is in an upward extended state, then the cavity edge 20 is higher than the bottom plate 10, and the upper end of the cloth blocking block 41 is flush with the upper end of the cavity 30.
[0053] 2. After the cloth is loaded, the cloth is pressed into the cavity 30; the cylinder piston rod of the blocking driving source 44 extends upward, driving the cloth blocking block 41 to move upward, so that the upper end of the cloth blocking block 41 is about 3-4 mm higher than the cavity 30, that is, the upper end of the cloth blocking block 41 extends upward from the cavity 30 by 3-4 mm. Figure 1 As shown, the front end of the cloth piece is pushed upward, so that the cloth piece pressed into the cavity 30 is in an easy-to-fold state, which facilitates the subsequent push plate to fold the left and right straight folded edges of the cloth piece. The height of the cloth piece blocking block 41 above the cavity surrounding edge 20 can be adjusted by adjusting the connection between the blocking drive source 44 and the transmission connection block 45.
[0054] 3. After the two straight folding edges of the cloth piece are folded, the cylinder piston rod of the blocking drive source 44 is retracted downward, driving the cloth piece blocking block 41 to move downward and reset; then, the two inclined folding edges at the front end of the cloth piece are folded.
[0055] 4. After all the cloth pieces are folded, the cylinder piston rod of the cavity lifting cylinder 52 is retracted downward, so that the cavity surrounding edge 20 is lowered and flush with the bottom plate 10, which is convenient for material removal.
[0056] In summary, the utility model effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
