Description

Trifolder

technical field

The utility model relates to the technical field of textile machinery, in particular to a three-folding device capable of realizing automatic folding of fabrics.

Background technique

When the cloth is processed into fabrics such as towels, bed sheets or curtains, it is necessary to hem the edges of the fabric to prevent the thread ends at the edges of the fabric from being scattered.

In the traditional hemming process, the workers usually fold the edge of the fabric first (usually three times to wrap the thread end inside to prevent the thread end from being exposed), and then guide the folded fabric into the sewing machine (specifically, it is also called roll side) for sewing. However, in the face of the current problems of difficult labor and higher and higher quality of market demand, the traditional method uses manual folding and sewing or semi-automatic equipment for sewing after folding, which requires a lot of manpower, slow work efficiency, and poor product quality. Also can't be promoted, can't reduce product price effectively, can't satisfy market demand.

Preferably, the positioning bar is fixed by a positioning plate, and the positioning plate is fixed or integrally formed with the bracket.

Preferably, the pressing plate is fixed to the positioning plate, and includes an inclined transition portion and a vertical guide portion, and the edge of the fabric that has completed the second fold is gradually pressed down by the inclined transition portion until it enters the guide portion, The edge of the fabric changes from an approximately horizontal shape to an approximately vertical shape, and when it continues to pass through the passage groove, it is shaped by the passage groove and the forming device to realize the third folding.

Preferably, the ends of the crimping strips have arcuate surfaces suitable for leading the fabric into the gap.

It can be seen that compared with the traditional manual folding method, the use of the three-folding device of the present invention can significantly improve the folding efficiency, thereby effectively improving the production capacity of the fabric and reducing the production cost.

Detailed ways

The structural principles and functional characteristics of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so as to understand the essence of the invention of the present utility model.

Referring to FIG. 1 , the three-folding device 100 provided in this embodiment is used to be fixed in front of a sewing machine to perform three-folding processing on fabrics such as bed sheets, curtains or towels. The three-folder 100 includes a bracket 1, a supporting plate 2, a base plate 3, a curling strip 4, a positioning strip 5, a positioning plate 6, a pressing plate 7, a forming device 8 and a guide nozzle 9, wherein the bracket 1 is used to be fixed on the front of the sewing machine , and make the pallet 2 parallel to the table or place the pallet 2 flat on the table. A crimp bar 4 is fixed above the supporting plate 2, and a certain gap 10 is formed between the crimping bar 4 and the supporting plate 2, and the gap 10 is suitable for allowing the edge of the fabric to pass through. The above-mentioned positioning strip 5, pressing plate 7 and forming device 8 are sequentially arranged along the length direction of the crimping strip 4, the positioning strip 5 is arranged at the beginning of the curling strip 4, the forming device 8 is arranged at the end of the curling strip 4, and the fabric edge enters from the beginning , after being folded, it is led out from the end and via the forming device 8 .

Specifically, the positioning strip 5 of the present invention is fixedly arranged on the side of the crimping strip 4, and there is also a gap reserved between the two for the passage of the fabric edge. The pressing plate 7 and the forming device 8 are fixedly arranged above the crimping bar 4 and also form a gap suitable for passing the fabric after crimping with the crimping bar 4 . Moreover, a passage groove 81 is formed between the forming device 8 and the end face of the crimping bar 4, and the passing groove 81 can guide the edge of the fabric to be crimped from one side of the crimping bar 4 to the other side of the crimping bar 4, thereby realizing Make a third fold over the edge of the fabric.

As for the first and second folds to the edges of the fabric, here's how it works:

Referring to Fig. 2, the end of the curling strip 4 is provided with an arc surface suitable for introducing the edge of the fabric into the above-mentioned gap 10, because the gap 10 between the curling strip 4 and the bottom plate 3 and the curling strip 4 and the positioning strip 5 The gaps between them are basically vertical. Therefore, after the fabric edge enters these two gaps, it becomes approximately perpendicular to the fabric itself, realizing the first folding process. As the fabric edge continues to move forward, the fabric edge that completes the first fold enters in the gap formed between the pressing plate 7 and the crimping bar 4 . It can be seen from the figure that the pressing plate 7 is fixed to the positioning plate 6, and the positioning plate 6 is fixed or integrally formed with the bracket 1. The pressing plate 7 includes an inclined transition portion 71 and a vertical guiding portion 72, and the guiding portion 62 is in the shape of an inverted triangle. The edge of the fabric that has completed the first fold is approximately at right angles. In the process of gradually entering the pressing plate 7, the vertical side of the edge of the fabric gradually becomes horizontal under the pressure of the transition portion 71, and finally the second fold is realized.

The principle of the third fold is specifically shown in Figures 3 and 4. The fabric edge that has completed the second fold enters the guide part 72 from the transition part 71, and the guide part 72 continues to press down on the fabric edge, so that the fabric edge finally becomes downward. The approximate vertical state, then, the fabric edge that is approximately vertical state passes through the passage groove 81 that is arranged obliquely between the crimping bar 4 terminal ends and the forming device bottom 7 parts, makes the fabric edge from the right side of the crimping bar 4 (Refer to the forward direction of the fabric) Move to the left side, at this time, the edge of the fabric is squeezed sideways, completes the third fold, and is immediately sent into the nozzle 9. The guide nozzle 9 is positioned on the same straight line as the crimp bar 4, and just above the edge of the fabric folded in three, and finally the folded fabric is sent into the sewing machine by the guide nozzle 3 for sewing. Figure 5 is the final rendering of the edge of the fabric after being folded three times. The sewing machine can close the inner side of the edge to sew the edge of the fabric, and wrap the thread ends on the innermost side to prevent the thread ends from being scattered and causing damage to the yarn. fabric.

To sum up, the three-folding device of the utility model has a simple structure, and the three-folding device can replace manual labor to realize fast folding of the fabric edge, effectively improve the production efficiency and product quality of the fabric, and can realize continuity, Fully automated production.

In the description of this specification, specific features, structures, materials or characteristics may be combined in any one or more embodiments or examples in an appropriate manner.

The above is only a specific embodiment of the present utility model, but the scope of protection of the present utility model is not limited thereto. Anyone familiar with the technical field can easily think of changes or changes within the technical scope disclosed by the utility model Replacement should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be determined by the protection scope of the claims.
