Technical Field

[0001] The invention belongs to the technical field of printing and dyeing equipment, and in particular relates to a cloth joint mechanism of a setting machine. Background Art

[0002] Fabric shaping is an important part of fabric making process. During production, the fabric will be flattened by rollers. Various fabrics such as cotton, chemical fiber, linen, wool, silk, and blended fabrics need to be flattened. After the fabric passes through the shaping machine, the wrinkled and uneven-edged fabric will become flat and smooth, and the touch and feel of the fabric will be enhanced.

[0003] When the shaping machine is shaping the same type of fabrics, it is necessary to sew the ends of the fabrics together to facilitate the shaping of the fabrics by the shaping machine. In the traditional fabric sewing process, the joints of two fabrics are usually manually connected and sewn by a sewing machine. In the manual sewing process, due to the wide width of the fabric, the fabric is prone to deviation during the sewing process. During the shaping process, the deviated joints will cause the wrong weft due to the different pulling forces at both ends of the fabric, thus affecting the shaping effect. Summary of the invention

[0021] A guide hole 15 is provided on the guide frame 11, and the guide hole 15 is aligned with the threading hole 8 in the lower wave protrusion 5. A driving wheel 16 is fixedly connected to the driving shaft of the driving motor 13, and a limiting wheel 17 is rotatably connected to the upper end of the supporting shaft 12; a limiting groove 18 is provided at the upper ends of the two limiting plates 14, and the limiting grooves 18 in the two limiting plates 14 are arranged perpendicular to each other, and the limiting groove 18 in the limiting plate 14 on the left side of the driving motor 13 is aligned with the guide hole 15; the rapier 10 is slidably fitted on the two limiting plates The rapier 10 is arranged in a limiting groove 18 at the upper end of the positioning plate 14 and is also attached to the limiting wheel 17; a plurality of tooth holes 19 are equidistantly arranged on the end face of the rapier 10 close to the driving motor 13, and a driving tooth 20 meshing with the tooth holes 19 is arranged on the outer ring surface of the driving wheel 16; the end of the rapier 10 is a pointed tip, and the end of the rapier 10 is passed through the guide hole 15, and a threading hole 21 is provided at the end of the rapier 10; when the upper mold 3 and the lower mold 2 are closed, the threading hole 8 in the lower wave protrusion 5 and the threading hole 8 in the upper wave protrusion 7 are in the same straight line.

[0022] The principle of the present invention is as follows: when the joint mechanism is used, the joint mechanism is first installed at the cloth feeding end of the setting machine. When the previous cloth is about to be set, the rear end of the cloth is inserted into the pin 6 of the lower die 2, and the tail of the cloth is placed on the lower wave protrusion 5 of the lower die 2. The head of the new cloth is placed on the tail end of the previous batch of cloth on the lower die 2, and the two telescopic cylinders 4 are controlled to retract, driving the upper die 3 to press down. The cloth presents a wave shape under the squeezing of the upper wave protrusion 7 and the lower wave protrusion 5. At the same time, the end of the rapier 10 The sewing thread is inserted into the threading hole 21, and the driving motor 13 is controlled to rotate, and the rapier 10 is driven to move through the driving wheel 16. The rapier 10 is made of a flexible material, generally made of glass fiber, and has high toughness. The driving teeth 20 on the driving wheel 16 are engaged with the tooth holes 19 on the rapier 10, driving the end of the rapier 10 to move leftward. During the movement, the blade of the rapier 10 is limited by the limiting groove 18 and the limiting wheel 17 on the limiting plate 14 to ensure the accuracy of the movement. The two limiting plates 14 are perpendicular to each other. The purpose of the straight setting is to reduce the overall structure size of the threading mechanism. When the installation space is sufficient, the two limit plates 14 can be arranged on the left and right sides of the driving motor 13 in parallel. The rapier 10 can also be made of rigid material, and the limit wheel 17 is omitted. Since the end of the rapier 10 is a pointed structure, it can be easily penetrated into the cloth under the power of the driving motor 13. When the upper mold 3 and the lower mold 2 are closed, the threading hole 8 in the lower wave protrusion 5 and the threading hole 8 in the upper wave protrusion 7 are in the same straight line. The rapier 10 can be understood as moving in a deep hole during the movement process, thereby improving the movement accuracy of the rapier 10 and preventing sewing from being offset. When the rapier 10 drives the sewing thread to pass through the cloth, the drive motor 13 drives the rapier 10 to move back, and the sewing thread remains on the cloth to complete the sewing connection between the cloths. After the connection is completed, the upper mold 3 rises. Due to the setting of the threading groove 9, the cloth with the sewing thread can be easily removed from the upper mold 3 and the lower mold 2, and the shaping machine can continue to drive the cloth for shaping.

[0023] In actual use, the width of the rapier 10 is between 0.5 mm and 0.8 mm, and the head is a pointed cone, which is convenient for penetrating the cloth.

[0024] Finally, it should be pointed out that the above embodiments are only representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention should be considered to belong to the protection scope of the present invention.
