Description

Technical Field

[0001] The utility model relates to the field of button sewing machines, in particular to a button sewing machine capable of automatically moving cloth. Background Art

[0002] Garment processing is a clothing production method that mainly uses modern machine processing and supplemented by manual processing. The buttonholes and buttons in clothing are usually processed by machines. The button sewing machine is a kind of automatic sewing machine. It completes the specified button sewing process according to the specified seam and can complete the sewing of different types of buttons. Most of the existing button sewing machines usually require manual movement of the fabric when sewing buttons on the fabric.

[0003] When a button sewing machine is sewing buttons on fabric, the fabric is generally placed flat on a sewing plate, and the needle of the button sewing machine will push down on the fabric to pierce and sew, which causes the surrounding fabric to move toward the sewing position, causing the fabric to sag toward the sewing position. If the depression is too large, the fabric will wrinkle, causing the subsequent button sewing direction of the fabric to shift. Therefore, a button sewing machine that automatically moves the fabric is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In the embodiment, Figure 1-4A button sewing machine for automatically moving cloth is given. The utility model includes a base 1, a mounting plate 2 is fixedly connected to the top of the base 1, a rotating shaft 3 is rotatably connected to the front side of the mounting plate 2, a button sewing machine body 4 is fixedly connected to the top of the base 1, a fixed block 5 located at the bottom of the button sewing machine body 4 is fixedly connected to the top of the base 1, a clearance groove is opened inside the fixed block 5, four springs 6 are fixedly connected inside the clearance groove and are symmetrically distributed in pairs in the front and back, the bottoms of the front and rear springs 6 are respectively fixedly connected to two U-shaped frames 7, three pressure wheels 8 are rotatably connected inside the two U-shaped frames 7, the tops of the two U-shaped frames 7 are respectively fixedly connected to connecting rods 9 that penetrate through and extend to the outside of the fixed block 5, the top of the connecting rod 9 is fixedly connected to a baffle 10, the rear side of the mounting plate 2 is fixedly connected to a motor 11, and the outside of the output shaft of the motor 11 is fixedly connected to a winding shaft 12 located on the right side of the fixed block 5.

[0028] The front side of the mounting plate 2 is rotatably connected to a first limiting rod 13 located between the rotating shaft 3 and the fixed block 5 , and the front side of the mounting plate 2 is fixedly connected to a second limiting rod 14 located between the fixed block 5 and the winding shaft 12 .

[0029] In this embodiment, in actual use, the cloth will pass through the bottom of the first limiting rod 13 and the second limiting rod 14 respectively. The two limiting rods provide angle turning points for the cloth, so that the cloth can be fixed more tightly.

[0030] The highest installation points of the first limiting rod 13 and the second limiting rod 14 are both lower than the top surface height of the fixing block 5 , and the first limiting rod 13 and the second limiting rod 14 are both thin in the middle and thick at both sides.

[0031] In this embodiment, in actual use, the cloth passes from under the first limit rod 13 and then from above the fixed block 5, and then from under the second limit rod 14. When the cloth passes through the two limit rods, it will be blocked by the thicker position of the limit rods, making it difficult for the cloth to slide off.

[0032] A button groove is provided inside the clearance groove, a button platform 15 is provided inside the button groove, button holes are provided inside the button platform 15, and the left and right side edges of the clearance groove are both arranged in an arc shape.

[0033] In this embodiment, in actual use, when the button sewing machine is sewing buttons, the needle will pass through the button sewing hole, and the cloth will be blocked by the button sewing platform 15. The button sewing platform 15 provides a support point for the cloth, and the arc-shaped fixing block 5 makes it easier for the cloth to pass smoothly.

[0034] The distance between the two U-shaped frames 7 and the bottom wall of the clearance groove is greater than the distance between the six pressure wheels 8 and the bottom wall of the clearance groove, and the multiple springs 6 are all in a compressed state.

[0035] In this embodiment, in actual use, the spring 6 in the compressed state will stretch, so that the pressure wheel 8 in the U-shaped frame 7 moves downward and presses the cloth. The cloth will drive the pressure wheel to rotate when moving, and the pressure wheel 8 close to the cloth allows the cloth to move left and right but not forward and backward.

[0036] The outer side of the rotating shaft 3 and the inner side of the reeling shaft 12 are both threadedly connected with limit baffles 16 , and the maximum diameters of the two limit baffles 16 are both larger than the maximum diameters of the rotating shaft 3 and the reeling shaft 12 .

[0037] In this embodiment, in actual use, the collection of cloth is generally rolled up, and the threaded limit baffle 16 can be disassembled to facilitate the placement of the rolled up cloth.

[0038] Working principle:

[0039] First, remove the limit baffle 16, put the rolled-up cloth on the outside of the rotating shaft 3, and then rotate and tighten the limit baffle 16, pass the cloth through the bottom of the first limit rod 13, the inside of the makeshift groove, and the bottom of the second limit rod 14 in sequence, and then fix it on the winding shaft 12. When the cloth passes through the makeshift groove inside the fixed block 5, it is necessary to pull up the two U-shaped frames 7 through the two baffles 10 to further compress the spring 6. At this time, the pressing wheel 8 is lifted to pass the cloth, and the baffle 10 is released. The spring 6 will press the pressing wheel 8 down again and press the cloth, and start the button sewing machine body 4 and the motor 11. The motor 11 drives the cloth to be rolled up, and the button sewing machine body 4 makes the needle pierce and fix the button downward, and the pressing wheel 8 presses the cloth and does not hinder the cloth from moving left and right.
