Description

Technical Field

[0001] The utility model belongs to the technical field of sewing machines, and in particular relates to an anti-curling elastic band control device. Background Art

[0002] Currently, when sewing elastic bands onto home textile products made of high-stretch knitted fabrics, the conventional method is for the operator to first stretch the elastic band and then drape it onto the sewing machine's operating table. The operator then drapes the fabric over the elastic band with one hand while manually stretching the elastic band underneath with the other, completing the entire sewing process. Furthermore, the size of the seam allowance for the lapped fabric and the elasticity ratio of the elastic band are determined by the operator's experience throughout the entire sewing process.

[0003] Based on this, the following disadvantages are likely to exist in the actual production process: 1. When the elasticity ratio of the rubber band is confirmed by manual stretching, the elasticity ratio of the sewn product will be inconsistent. At this time, the rubber band that is stretched in place on the surface will fold more after relaxation, and the rubber band that is not stretched enough on the surface will fold loosely after relaxation, which will lead to poor appearance of the finished product and fail to meet customer quality requirements; 2. It is easy to pull or rub the fabric during operation, which will cause the fabric curling and deformation, especially when sewing highly elastic fabrics; 3. Due to the lack of a restrictive structure, the rubber band is easily cut by the blade provided on the machine body, resulting in low production efficiency, obstructed production flow and other problems; 4. In order to ensure the quality of sewing, the above-mentioned workmanship requires the operator to frequently change hands over a short distance. Therefore, it is not only difficult to ensure that the fabric is not deformed, but also easy to cause the fingers to be too close to the needle, which is very dangerous.

[0004] Therefore, when the above-mentioned manual stretching rubber band method is used to sew home textile products, clothing products and other products, it is prone to problems such as poor quality, low production capacity, and high risk, and cannot meet the existing production needs of textile factories. Utility Model Content

[0005] The technical problem solved by the utility model is to provide an anti-curling elastic band control device, which can not only control the position of the fabric, but also control the position and elasticity of the elastic band, so as to ensure that the elastic band and the fabric can be sewn together evenly, synchronously and flatly, and avoid the elastic band from being cut, thereby improving the production efficiency and production quality of home textile products containing elastic bands, and meeting the production needs of existing textile products.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: an anti-curling rubber band control device, which includes a rubber band control component and a fabric control component arranged in sequence along the forward direction of the rubber band, the rubber band control component includes a fixing part 1 that can be installed on the sewing machine operating table, a fixing frame is provided on one side of the fixing part 1, and a rubber band channel is provided inside the fixing frame, and a threaded through hole is penetrated on the side of the fixing frame used to stay away from the sewing foot, and an adjustment bolt is connected to the threaded through hole, and one end of the adjustment bolt is extended into the rubber band channel through the threaded through hole and is connected to the elastic force adjustment pressure plate; the fabric control component includes a fixing part 2 that can be installed on the sewing machine operating table, a rubber band fabric common channel is provided above the fixing part 2, an external curling protection controller is provided at the front end of the rubber band fabric common channel, an anti-buckle control part is provided at the rear end of the rubber band fabric common channel, and a matching vertical plate is provided on one side of the rubber band fabric common channel. Based on this, when the present invention is installed on an existing sewing machine, the elastic cord can be introduced to the presser foot position after passing through the elastic cord channel and the elastic cord and fabric channel in sequence. The elastic force of the elastic cord can be adjusted by adjusting the elastic force adjustment plate to ensure uniform elastic force, eliminating the need for the operator to manually stretch and control the elastic force of the elastic cord. The position of the elastic cord is constrained by the fixed frame to prevent the elastic cord from being cut by the blade. At the same time, the fabric can be introduced to the presser foot position after passing through the elastic cord and fabric channel. During the process of passing through the elastic cord and fabric channel, the cooperation of the vertical plate, the external curl protection controller, and the anti-buckle control component naturally flattens the curled and buckled pieces. This eliminates the need for the operator to frequently change hands over short distances, achieving smooth sewing of the elastic cord and fabric, thereby ensuring product quality.

[0007] Furthermore, one end of the first fixing member is provided with a U-shaped support arm, which can be clamped to the sewing machine operating table through the U-shaped support arm to prevent the entire rubber band control assembly from being driven by the force of the rubber band during operation. In addition, the U-shaped support arm and the first fixing member can be two separate parts or a single piece that is bent and formed integrally.

[0008] Furthermore, an outlet stopper is provided on one side of the fixing frame, and the outlet stopper can be glued into the slot of the U-shaped support arm or glued between the U-shaped support arm and the fixing member 1. In this way, in addition to constraining the position of the elastic band through the fixing frame, the outlet stopper can further constrain the elastic band's outlet position, preventing the elastic band from being cut by the blade and ensuring that the elastic band is sewn parallel to the fabric.

[0009] Furthermore, a horizontal plate is provided at the upper end of the vertical plate, and a common passage for the elastic fabric is formed between the lower surface of the horizontal plate and the upper surface of the second fixing member. An outward roll protection controller is provided at the front end of the horizontal plate, and an anti-buckle control member is provided at the rear end of the horizontal plate. The outward roll protection controller cooperates with the horizontal plate, the vertical plate and the anti-buckle control member to naturally flatten the outward rolled and buckled fabric, so that the fabric is in a flat state and enters the presser foot for sewing.

[0010] Furthermore, the anti-buckle control member includes an upper anti-buckle control member and a lower anti-buckle control member. The upper anti-buckle control member is located at the rear end of the horizontal plate, and one end of the upper anti-buckle control member extends out of the elastic fabric passage and then protrudes downward to form an upper anti-buckle portion. The lower anti-buckle control member is located at the rear end of the second fixing member, and one end of the lower anti-buckle control member extends out of the elastic fabric passage and then protrudes upward to form a lower anti-buckle portion. The lower anti-buckle portion is located between the upper anti-buckle portion and the mating vertical plate. In this way, when the fabric moves to the anti-buckle control member during the sewing process, the upper and lower anti-buckle control members can naturally flatten the reversed edge of the fabric, ensuring that the fabric is flat when it enters the presser foot position.

[0011] Furthermore, the anti-rolling controller includes a horizontal fixing portion fixedly mounted above the horizontal plate. A downwardly bent anti-rolling vertical plate is formed at the front end of the fixing portion. A gap (I) exists between the lower end of the anti-rolling vertical plate and the upper surface of the second fixing member, and a gap (II) exists between the side edge of the anti-rolling vertical plate and the mating vertical plate. This allows the fabric to pass through these gaps (I) and (II) into the common passage for the elastic band and fabric during sewing. At gap (II), the side edge of the anti-rolling vertical plate and the mating vertical plate provide combined restraint to prevent fabric from turning outward.

[0012] Furthermore, a stabilizing vertical plate is bent downward on the end of the fixing part 2 away from the sewing machine presser foot, and can be clamped on the sewing machine operating table through the stabilizing vertical plate to prevent the entire fabric control assembly from being driven by the force of the rubber band or the fabric during operation.

[0013] Furthermore, the second fixing member is integrally bent together with the vertical plate, the horizontal plate and the anti-buckle control member, and can be processed and manufactured by equipment such as a bending machine.

[0014] It can be seen from the above technical solution that the utility model has the following advantages: on the one hand, the utility model can flexibly adjust the elastic force of the rubber band through the elastic force adjustment pressure plate with adjustable position set at the rubber band control component to ensure that the elastic force of the rubber band is uniform, and there is no need for the operator to manually stretch and control the elastic force of the rubber band, thereby ensuring that the elastic ratio of the sewn product is always consistent; on the other hand, by cooperating with the vertical plate and the external roll protection controller and the anti-buckle control component, the curled and buckled pieces can be naturally stretched flat, and the operator does not need to frequently change hands for short distances to operate, so that smooth sewing of the rubber band and the fabric can be achieved, thereby ensuring product quality.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1 to 2 As shown, the utility model discloses an anti-curling elastic band control device, which includes an elastic band control assembly and a fabric control assembly arranged in sequence along the elastic band's forward direction. The elastic band control assembly is installed at the front end of the sewing machine operating table when in use, and the fabric control assembly is installed on the sewing machine operating table when in use and is located between the elastic band control assembly and the presser foot.

[0021] Specifically, the rubber band control component includes a fixing part 4 that can be installed on the sewing machine operating table. The fixing part 4 can be glued to the sewing machine operating table using auxiliary tools such as tape, or disassembled and installed on the sewing machine operating table using fasteners such as bolts, or can be clamped on the sewing machine operating table using its own structure. For example, a U-shaped support arm 16 is provided on the back side of the fixing part 4, and is clamped on the sewing machine operating table through the slot structure of the U-shaped support arm 16 to prevent the entire rubber band control component from being driven by the force of the rubber band during operation. Moreover, the U-shaped support arm 16 and the fixing part 4 can be two separate components or an integral part that is bent and formed as a whole.

[0022] Moreover, a fixing frame 1 is provided on the front side of the fixing part 4, and an elastic band channel is provided inside the fixing frame 1. A threaded through hole is penetrated on the side of the fixing frame 1 that is used to stay away from the sewing foot, and an adjusting bolt 2 is threadedly connected to the threaded through hole. One end of the adjusting bolt 2 is extended into the elastic band channel through the threaded through hole and is connected to an elastic force adjustment pressure plate 3.

[0023] In this way, when the elastic control assembly of the present invention is installed on an existing sewing machine, the elastic can be introduced into the presser foot position after passing through the elastic channel and the elastic fabric common channel in sequence. At this time, the position of the elastic force adjustment plate 3 can be adjusted by screwing the adjustment bolt 2, thereby changing the distance between the elastic force adjustment plate 3 and the rear side wall of the fixed frame 1, and then changing the friction between the elastic and the elastic force adjustment plate 3 and the rear side wall of the fixed frame 1, thereby achieving the purpose of adjusting the elastic force of the elastic, ensuring uniform elastic force of the elastic, and eliminating the need for the operator to manually stretch and control the elastic force of the elastic. At the same time, the present invention can also constrain the position of the elastic by the fixed frame 1 to prevent the elastic from being cut by the blade.

[0024] In addition, as a preferred embodiment, the present invention can also be provided with an outlet stopper 15 on the right side of the fixing frame 1. The outlet stopper 15 can be glued into the slot of the U-shaped support arm 16 or glued between the U-shaped support arm 16 and the fixing member 4. In this way, in addition to constraining the position of the elastic band through the fixing frame 1, the outlet stopper 15 can further constrain the outlet position of the elastic band, thereby preventing the elastic band from being cut by the blade and ensuring that the elastic band is sewn parallel to the fabric.

[0025] The fabric control assembly includes a second fixing part 6 that can be installed on the sewing machine operating table. The second fixing part 6 can be glued to the sewing machine operating table using auxiliary tools such as tape, or disassembled and installed on the sewing machine operating table using fasteners such as bolts, or can be clamped on the sewing machine operating table using its own structure. For example, the front end of the second fixing part 6 is bent downward to form a stabilizing vertical plate 5, and the stabilizing vertical plate 5 is clamped on the front end of the sewing machine operating table to prevent the entire fabric control assembly from being driven by the force of the rubber band or the fabric during operation.

[0026] Moreover, a common passage for elastic fabric is provided above the second fixing member 6, the common passage for elastic fabric is aligned with the elastic channel, and an outward roll protection controller is provided at the front end of the common passage for elastic fabric, an anti-buckle control part is provided at the rear end of the common passage for elastic fabric, and a matching vertical plate 9 is provided on the right side of the common passage for elastic fabric.

[0027] like Figure 1 、 Figure 2 As shown, the anti-rolling controller includes a horizontal fixing portion 8, which is fixedly mounted above a horizontal plate 10. A downwardly bent anti-rolling vertical plate 7 is formed at the front end of the horizontal fixing portion 8. A gap 1 exists between the lower end of the anti-rolling vertical plate 7 and the upper surface of the second fixing member 6, and a gap 2 exists between the side of the anti-rolling vertical plate 7 and the mating vertical plate 9. During the fabric sewing process, the elastic band can enter the elastic band and fabric common passage through the gap 1, and the fabric can pass through the gaps 1 and 2 into the elastic band and fabric common passage. At gap 2, the side of the anti-rolling vertical plate 7 and the mating vertical plate 9 jointly restrain the fabric from turning outward.

[0028] The anti-buckle control member includes an upper anti-buckle control member 11 and a lower anti-buckle control member 14. The upper anti-buckle control member 11 is disposed at the rear end of the horizontal plate 10, and the right end of the upper anti-buckle control member 11 extends out of the elastic fabric passage and then protrudes downward to form an upper anti-buckle portion 12. The lower anti-buckle control member 14 is disposed at the rear end of the second fixing member 6, and the right end of the lower anti-buckle control member 14 extends out of the elastic fabric passage and then protrudes upward to form a lower anti-buckle portion 13. The lower anti-buckle portion 13 is disposed between the upper anti-buckle portion 12 and the mating vertical plate 9. In this way, during the sewing process, when the fabric moves to the anti-buckle control member, the upper anti-buckle control member 11 and the lower anti-buckle control member 14 can naturally flatten the buckled edge, ensuring that the fabric is flat when it enters the presser foot position.

[0029] The matching vertical plate 9 is integrally bent together with the second fixing member 6 , the horizontal plate 10 and the buckle-proof control member, and can be manufactured by equipment such as a bending machine.

[0030] Thus, when the fabric control assembly of the present invention is installed on an existing sewing machine, the fabric can first pass through the gaps 1 and 2 between the outer curl protection controller and the second fixing member 6 into the elastic fabric common passage, then pass through the anti-buckle control member to exit the elastic fabric common passage and be introduced into the presser foot position. Furthermore, during the passage through the elastic fabric common passage, the fabric can naturally flatten the curled and buckled pieces by cooperating with the vertical plate 9, the outer curl protection controller, and the anti-buckle control member. This eliminates the need for the operator to frequently change hands over short distances, thus achieving smooth sewing of the elastic and fabric, thereby ensuring product quality.
