Description

Technical Field

[0001] The utility model relates to the technical field of sewing, in particular to an automatic edge binding device for a blanket. Background Art

[0002] The sewing machine uses a sewing needle and stitches to sew the edge of the blanket, fixing the webbing or ribbon to the blanket so that the edge can withstand daily use and friction. This stitching method can ensure that the edge is firm and strong, preventing it from loosening or breaking.

[0003] The Chinese patent discloses a zigzag double needle sewing machine (authorization announcement number CN201372356Y) comprising a machine head, a bottom plate, a needle clamp and two needles fixed to the needle clamp, wherein the machine head is fixed to the bottom plate, the needle clamp is connected to the machine head, and a detachable mechanism is provided between the needle clamp and the machine head. The utility model has the advantages of high needle positioning accuracy, convenient disassembly, replacement and maintenance, etc.

[0004] This patented technology allows for convenient maintenance and replacement of needles during use, but there are still some shortcomings during use. When sewing large-sized blankets, the sewing time is long, the table supporting the fabric is small, and the edge cloth strips need to be pressed and moved manually to push the blanket, which can easily cause the blanket to deviate during the pushing process, increasing the possibility that the edge cloth strips are easily deviated or even detached. Therefore, those skilled in the art provide an automatic blanket edge binding device to solve the problems raised in the above background technology. Utility Model Content

The blanket is laid flat on the upper slide plate. When the blanket is hemmed, the upper slide plate and the lower slide plate are directly pushed, so that the blanket is laid flat and the cloth strips are pre-hemmed, which reduces the risk of the blanket or cloth being offset during the feeding process, or even the risk of the cloth strips being separated, and improves the stability of the sewing during the blanket hemming process.

[0030] At the same time, a rotating component is arranged at the lower end of the placing component, and the placing component can be rotated to drive the blanket laid flat on the upper end of the upper slide plate to rotate, and after the rotation, it can cooperate with the sewing machine to perform reciprocating movement in the wiring process to push the cloth, thereby avoiding adjusting the position of the blanket after the single-sided edge sewing of the blanket, and making the blanket edge sewing more convenient. In addition, the rotating component is fixed after use to avoid rotation of the rotating component during use, and the blanket edge sewing is stable to use.

[0031] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The support assembly 200 includes a support ring 201, a bottom plate 203 located below the support ring 201, and the bottom plate 203 is annular;

[0050] The placement component 100 is located at the upper end of the fixing component 400;

[0051] The placement component 100 includes a mounting ring 102, the mounting ring 102 is located above the support ring 201, a mounting frame 109 located at the upper end of the support ring 201, a lower slide plate 104 located above the mounting frame 109, an upper slide plate 103 located above the lower slide plate 104, tie bars 106 located at both ends of the upper slide plate 103 and symmetrically distributed, an upper slider 105 located at the lower end of the upper slide plate 103 and symmetrically distributed, a travel rod 112 located at one end of the lower slide plate 104, a travel hole 111 opened inside the mounting frame 109 and passing through the front and rear ends of the mounting frame 109, lower sliders 108 located at the lower end of the lower slide plate 104 and equidistantly distributed, a slide seat 110 located at both sides of the upper end of the mounting frame 109, a ball 115 rotatably mounted on the lower end of the mounting ring 102, and the ball 115 is equidistantly distributed, and a circular slide rail 114 opened inside the upper end of the support ring 201;

[0052] The sewing machine body 300 is located on one side above the placement assembly 100;

[0053] A symmetrically distributed sliding groove is provided inside the upper end of the lower sliding plate 104, and the upper sliding block 105 is slidably installed inside the sliding groove.

[0054] The lower slide block 108 is slidably sleeved on the outer wall of the slide seat 110 . Both ends of the lower slide block 104 are provided with mounting grooves 107 . One end of the tie rod 106 is connected to the inner wall of the mounting groove 107 .

[0055] One end of the travel rod 112 slides through the travel hole 111. One end of the travel rod 112 is U-shaped, and the U-shaped end is connected to the outer wall of the upper slide plate 103. A limit block 113 is set at one end of the travel rod 112. The radius of the limit block 113 is smaller than the radius of the travel hole 111. A limit ring is embedded in the rear end opening of the travel hole 111, and the radius of the limit ring is smaller than the radius of the limit block 113.

[0056] The ball bearing 115 is rollingly mounted inside the slide rail 114 .

[0057] Performing the use of the placement component 100;

[0058] The blanket is laid flat on the upper slide 103 and is always located in the needle groove 101 at the lower end of the sewing machine body 300, and the hemming fabric is sleeved on the outer side of the blanket and located at the upper end of the needle groove 101. After the blanket is laid, the sewing machine body 300 performs sewing and hemming processing on the blanket, and the lower slide 104 is pushed during the processing, and the lower slide 108 slides on the upper end of the slide seat 110 to push the upper slide 103, and the laid blanket moves back and forth with the upper slide 103 to perform sewing processing;

[0059] After single-sided sewing, the ball bearing 115 is used to rotate ninety degrees on the upper end of the slide rail 114. After the rotation, the upper slide plate 103 that slides laterally forms a reciprocating sliding stroke trajectory. The upper slide block 105 slides inside the slide groove to achieve repeated sliding of the upper slide plate 103. After the upper slide plate 103 is relaxed, it is restored to the upper end of the lower slide plate 104 through the elasticity of the tensioning rod 106 itself. The sewing process avoids the manual pushing of the blanket to tidy up the edge fabric. The blanket and the fabric are pre-treated. The sewing process reduces the problems of misalignment and detachment, and the stability and convenience of the sewing process are improved.
