Description

Technical Field

[0001] This utility model relates to the field of school uniform processing technology, and in particular to a label sewing device for school uniform processing. Background Technology

[0002] In the production of school uniforms, the sewing of school badges is a crucial process, as its quality directly affects the overall appearance and durability of the uniforms. Traditionally, school badge sewing relies heavily on manual labor. Workers first attach the badge to the appropriate position on the uniform, then manually operate a sewing machine to sew along the badge's edge. Because school badges are often circular or have a certain curvature, operators need to frequently adjust the uniform's position and angle to ensure even stitching and a neat outline.

[0003] Currently, while common semi-automatic sewing equipment possesses a certain degree of automation, it still has significant shortcomings when handling curved or circular sewing tasks. On the one hand, manual turning of the fabric easily leads to uneven stitching, obvious start and end points, and crooked stitches. On the other hand, the relative slippage between the school badge and the fabric further affects sewing accuracy and finished product quality. In addition, manual operation is labor-intensive and inefficient, making it difficult to meet the demands of large-scale, high-efficiency school uniform production.

[0004] Therefore, there is an urgent need for a school uniform marking sewing device that can accurately position, stably press, and rotate the school badge at a uniform speed, and work with the sewing machine head to complete high-quality and high-efficiency sewing work, thereby improving the automation level and product consistency of school uniform production. Utility Model Content

[0005] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0006] Therefore, one objective of this utility model is to provide a marking sewing device for school uniform processing, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0007] To achieve the above objectives, one embodiment of the present invention provides a marking sewing device for school uniform processing, including a machine base, a machine head, and a needle. The machine head is fixedly connected to the top of the machine base, and the needle is fixedly connected to the output end of the machine head. The machine has a groove on its top surface and a turntable is movably connected in the groove. The turntable is a disc and a number of anti-slip protrusions are fixedly connected to its top surface. A geared motor is detachably connected to the bottom surface of the machine base, and the output end of the geared motor is fixedly connected to the turntable. The top surface of the turntable is flush with the top surface of the machine base. A bracket is fixedly connected to the edge of the top surface of the machine base. The bracket is divided into a horizontal part and a vertical part. The bottom end of the vertical part of the bracket is fixedly connected to the machine base. An electric cylinder is fixedly connected to the end of the horizontal part of the bracket. The output end of the electric cylinder is fixedly connected to a connector, and a rotating component is movably connected to the outer surface of the connector, with the bottom of the rotating component facing the turntable.

[0008] Preferably, in any of the above embodiments, the needle is located on the upper side of the turntable, and the anti-slip protrusion is a silicone particle.

[0009] The above technical solution utilizes a device specifically designed for school uniform manufacturing, where circular school badges are sewn onto corresponding school uniform fabrics. The machine head is a conventional automatic sewing machine head.

[0010] The basic working principle of this device is as follows: the school badge is initially glued to the corresponding position on the fabric. Then, the school badge and fabric are placed on the machine table, with the school badge on the turntable and its edge below the needle. The electric cylinder is activated, and its output end pushes out. The rotating component presses the school badge and fabric tightly onto the turntable. The rotating component can rotate. The geared motor is activated, and the turntable rotates, the rotating component rotates, and the fabric and school badge rotate. The machine head starts, and the needle continuously outputs, sewing the edge of the school badge. The school badge is firmly and evenly sewn onto the corresponding position on the fabric without manual turning, resulting in a good sewing effect.

[0011] Preferably, in any of the above embodiments, the anti-slip protrusions are bonded to the top surface of the turntable, and the anti-slip protrusions are arranged in a circumferential array about the axis of the turntable.

[0012] Using the above technical solution: Place the school uniform fabric with the school badge attached stably on the machine table, paying particular attention to accurately placing the school badge on the turntable and adjusting its position so that its edge is directly below the needle tip, ensuring that subsequent sewing completely covers the edge of the school badge. Start the electric cylinder; since the electric cylinder is vertically mounted at the end of the horizontal section of the support, its output end will push downwards. A bearing is fixedly connected around the connector at the end of the electric cylinder output end, and the rotating component is fitted onto this bearing, allowing for flexible rotation. As the electric cylinder output end pushes out, the rotating component moves downwards, pressing the school badge and school uniform fabric firmly onto the turntable. At this point, the top surface of the turntable is flush with the top surface of the machine table, and several circularly arrayed, anti-slip silicone granules are fixedly connected to the top surface of the turntable. These anti-slip protrusions effectively increase the friction between the school badge / fabric and the turntable, preventing slippage during rotation and ensuring sewing accuracy. The geared motor is started. It is vertically mounted on the bottom of the machine base and connected to the base via a flange on its end face. Its output end is fixedly connected to the turntable's shaft via a coupling. Driven by the geared motor, the turntable begins to rotate. Because the rotating component presses the school badge and fabric tightly against the turntable, and this component is rotatable, the badge and fabric rotate synchronously with the turntable. Simultaneously, the sewing machine head is started. This is a standard automatic sewing machine head; its output needle continuously reciprocates up and down, sewing along the edge of the school badge according to a preset sewing program. As the badge and fabric continue to rotate, the needle evenly and completely sews the edge of the badge onto the uniform fabric, ultimately securing the badge firmly and evenly in its corresponding position.

[0013] The entire sewing process does not require manual rotation of the fabric. Through the coordinated rotation of the turntable and rotating parts, as well as the automatic sewing of the machine head, the school badge is sewn automatically and precisely, greatly improving sewing efficiency and quality.

[0014] Preferably, in any of the above schemes, the geared motor is installed vertically, and the geared motor is connected to the bottom surface of the machine base through the flange on its end face.

[0015] Preferably, in any of the above schemes, the output end of the geared motor is fixedly connected to the rotating shaft of the turntable via a coupling, and the electric cylinder is installed vertically.

[0016] Preferably, in any of the above embodiments, a bearing is fixedly connected around the joint and a rotating part is fitted onto this bearing.

[0017] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows: This school uniform processing identification sewing device places the school badge and fabric on the machine table. The school badge rests on a turntable with its edge below the needle. Activating the electric cylinder causes its output to push outwards, pressing the badge and fabric firmly onto the turntable. Anti-slip protrusions, made of silicone granules, are evenly distributed in a circumferential array on the turntable through an adhesive method to increase friction and prevent the badge from slipping. The turntable rotates; activating the geared motor causes the turntable, turntable, and fabric / badge to rotate, activating the machine head and continuously outputting needles to sew the edge of the badge, firmly and evenly sewing it onto the corresponding part of the fabric. No manual turning is required, resulting in excellent sewing quality.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0023] like Figure 1-4 As shown, the marking sewing device for school uniform processing includes a machine base 1, a machine head 2, and a needle 3. The machine head 2 is fixedly connected to the top of the machine base 1, and the needle 3 is fixedly connected to the output end of the machine head 2. A groove is opened on the top surface of the machine 1, and a turntable 4 is movably connected in the groove. The turntable 4 is a disc, and several anti-slip protrusions 5 are fixedly connected to the top surface of the turntable 4. A geared motor 6 is detachably connected to the bottom surface of the machine base 1, and the output end of the geared motor 6 is fixedly connected to the turntable 4. The top surface of turntable 4 is flush with the top surface of machine base 1. A bracket 7 is fixedly connected to the edge of the top surface of machine base 1. The bracket 7 is divided into a horizontal part and a vertical part. The bottom end of the vertical part of the bracket 7 is fixedly connected to machine base 1, and the end of the horizontal part of the bracket 7 is fixedly connected to an electric cylinder 8. The output end of the electric cylinder 8 is fixedly connected to a connector 9, and a rotating part 10 is movably connected to the outer surface of the connector 9. The bottom of the rotating part 10 faces the turntable 4.

[0024] Example 1: The needle 3 is located on the upper side of the turntable 4, and the anti-slip protrusions 5 are made of silicone particles. The anti-slip protrusions 5 are bonded to the top surface of the turntable 4 and are arranged in a circumferential array about the axis of the turntable 4. The geared motor 6 is installed vertically and is connected to the bottom surface of the machine base 1 through the flange on its end face. The output end of the geared motor 6 is fixedly connected to the rotating shaft of the turntable 4 through a coupling. The electric cylinder 8 is installed vertically. A bearing is fixedly connected around the connector 9, and the rotating part 10 is fitted on this bearing.

[0025] Example 2: This device is specifically designed for school uniform manufacturing, specifically for sewing circular school badges onto corresponding school uniform fabrics. Machine head 2 is a conventional automatic sewing machine head.

[0026] The basic working principle of this device is as follows: the school badge is initially pasted onto the corresponding part of the fabric with adhesive. Then, the school badge and fabric are placed on the machine table 1, with the school badge placed on the turntable 4. The edge of the school badge is located below the needle 3. The electric cylinder 8 is started, and the output end of the electric cylinder 8 pushes out. The rotating part 10 presses the school badge and fabric tightly onto the turntable 4. The rotating part 10 can rotate. The reduction motor 6 is started, the turntable 4 rotates, the rotating part 10 rotates, the fabric and school badge rotate, the machine head 2 is started, and the needle 3 continuously outputs, sewing the edge of the school badge, firmly and evenly sewing the school badge onto the corresponding part of the fabric.

[0027] Example 3: Place the school uniform fabric with the school badge attached smoothly on the machine table 1. Pay special attention to accurately placing the school badge on the turntable 4 and adjust its position so that its edge is directly below the needle tip 3, ensuring that subsequent sewing completely covers the edge of the school badge. Start the electric cylinder 8. Since the electric cylinder 8 is vertically mounted at the end of the horizontal part of the bracket 7, its output end will push downwards. A bearing is fixedly connected around the connector 9 at the end of the output end of the electric cylinder 8, and the rotating part 10 is fitted on this bearing, allowing the rotating part 10 to rotate flexibly. As the output end of the electric cylinder 8 pushes out, the rotating part 10 will move downwards, pressing the school badge and school uniform fabric tightly onto the turntable 4. At this time, the top surface of the turntable 4 is flush with the top surface of the machine table 1, and several silicone anti-slip protrusions 5 are fixedly connected to the top surface of the turntable 4 in a circumferential array. These anti-slip protrusions 5 can effectively increase the friction between the school badge and fabric and the turntable 4, preventing slippage during rotation and ensuring sewing accuracy. The geared motor 6 is started. It is vertically mounted on the bottom of the machine base 1 and connected to the bottom of the machine base 1 via a flange on its end face. Its output end is fixedly connected to the rotating shaft of the turntable 4 via a coupling. Driven by the geared motor 6, the turntable 4 begins to rotate. Because the rotating component 10 presses the school badge and fabric tightly onto the turntable 4, and the rotating component 10 is rotatable, the school badge and fabric rotate synchronously when the turntable 4 rotates. Simultaneously with the rotation of the school badge and fabric by the turntable 4, the sewing head 2 is started. The sewing head 2 is a conventional automatic sewing machine head. Its output needle 3 continuously reciprocates up and down, sewing along the edge of the school badge according to a preset sewing program. As the school badge and fabric continue to rotate, the needle 3 can evenly and completely sew the edge of the school badge onto the school uniform fabric, ultimately securing and evenly sewing the school badge to the corresponding position on the fabric.

[0028] The working principle of this utility model is as follows: The operator first places the circular school badge, which has been preliminarily glued to the school uniform fabric, steadily on machine 1, ensuring that the badge is accurately positioned on the top surface of turntable 4. The position is adjusted so that the edge of the badge is directly below the needle tip 3. The electric cylinder 8 is then activated; its output end pushes downwards, moving the rotating component 10 downwards and pressing the badge and uniform fabric firmly onto turntable 4. Anti-slip protrusions 5 effectively prevent the badge from slipping on the fabric during rotation.

[0029] Then, the geared motor 6 is started, driving the turntable 4 to rotate at a constant speed. Since the rotating component 10 is movably connected to the connector 9 via a bearing, it can rotate together with the turntable 4, thus causing the school badge and fabric to rotate synchronously. Simultaneously, the sewing head 2 is started, controlling the needle 3 to reciprocate up and down, continuously sewing along the edge of the school badge. As the turntable 4 continues to rotate, the needle 3 can completely and evenly sew the school badge around its circumference, thus firmly attaching the school badge to the school uniform fabric.

[0030] The entire sewing process does not require manual rotation of the fabric, which significantly improves sewing efficiency and quality, and is especially suitable for mass production of school badges.

[0031] Compared with the prior art, the present invention has the following advantages: This school uniform processing identification sewing device places the school badge and fabric on machine base 1. The school badge is placed on turntable 4, with its edge below needle 3. When electric cylinder 8 is activated, its output end extends, and rotating component 10 presses the school badge and fabric firmly onto turntable 4. Anti-slip protrusions 5, made of silicone granules, are evenly distributed in a circumferential array on turntable 4 through an adhesive method to increase friction and prevent the school badge from slipping off the fabric. Rotating component 10 is rotatable. Activating reduction motor 6 causes turntable 4 to rotate, rotating component 10 to rotate, and the fabric and school badge to rotate. Machine head 2 starts, and needle 3 continuously outputs, sewing the edge of the school badge, firmly and evenly sewing the badge onto the corresponding part of the fabric. No manual turning is required, resulting in excellent sewing quality.
