Description

Technical Field

[0001] The utility model relates to sewing machine equipment, in particular to a shaping device of a sewing machine. Background Art

[0002] The process of splicing elastic bands into loops uses bundles or rolls of elastic bands as raw material. These bands are cut into sections and sewn into loops. During this production process, irregular wrinkles or twists in the fabric bands need to be ironed and smoothed to ensure the smoothness of the elastic bands before entering the subsequent process. This prevents uneven surfaces and uneven loop diameters. Existing methods typically involve manually ironing and smoothing the elastic band raw material, which is labor-intensive and inefficient.

[0003] Existing technologies also use automation to flatten the rubber band, such as publication number CN219470398U, which also uses left and right plywood to flatten the rubber band. The left and right plywood are relatively long, and due to the influence of assembly accuracy, the two cannot ensure that the rubber band is fully in contact with the right plywood for heating treatment when clamping it.

[0032] The following is combined with Figure 1-3 The utility model is further described in detail with examples.

[0033] Example 1

[0034] A shaping device for a sewing machine includes a frame 10, in which an ironing assembly 11 for ironing an elastic band is installed. The ironing assembly 11 includes a driver 111, a pressure plate 112, a heating plate 113, and a high-temperature resistant cushion 114. In this embodiment, the driver 111 is a cylinder. In other embodiments, it can also be an oil cylinder or a screw slider structure. The high-temperature resistant cushion 114 is fixed to the pressure plate 112. The shape of the high-temperature resistant cushion 114 is the same as that of the pressure plate 112. The high-temperature resistant cushion 114 completely covers the inner end surface of the pressure plate 112. The high-temperature resistant cushion 114 is arranged between the pressure plate 112 and the heating plate 113. The driver 111 is connected to the pressure plate 112 and pushes it to move back and forth toward the heating plate 113. The high-temperature resistant cushion 114 has a certain elastic function and can drive the elastic band to fully contact the heating plate 113.

[0035] The number of high-temperature resistant cushions 114, the number of pressure plates 112, and the number of drivers 111 all correspond one to one. In this embodiment, there are at least two pressure plates 112. In this embodiment, there are three high-temperature resistant cushions 114, the number of pressure plates 112, and the number of drivers 111. The drivers 111 are fastened to the frame 10 by screws. Due to the long length of the existing pressure plate, when the driver pushes it back and forth, it needs to be repeatedly adjusted to ensure that the pressure plate is in full contact with the heating plate, which is time-consuming and labor-intensive, and has high process requirements. The segmented pressure plate 112 reduces the length and reduces the process requirements, ensuring that the pressure plate 112 can be more easily and fully contacted with the heating plate 113.

[0036] The frame 10 includes a main support 101, a left cover 102 and a right fixed cover 103. The left cover 102 is hinged on the main support 101, and the right fixed cover 103 is fixed to the main support 101 by screws. When the left cover 102 is flipped and covered on the main support 101, the left cover 102 and the right fixed cover 103 form a circumferentially closed chamber. The rubber band enters from the upper port of the frame 10 and exits from its lower port.

[0037] A first heat shield 12 is installed between the heating plate 113 and the main support 101, and is fixed to the main support 101. A second heat shield 13 is installed between the main support 101 and the right fixed cover 103, and is fixed to the right fixed cover 103. This device generates a large amount of heat during heating and setting. Without heat insulation measures, the frame 10 would be very hot to the touch, posing a certain safety hazard. The addition of the first and second heat shields 12, 13 provides secondary insulation, thereby preventing the right fixed cover 103 from being too hot.

[0038] The main support 101 and the right fixed cover 103 are both "L"-shaped when projected from above. The back plate 1011 of the main support is connected to the back plate 1031 of the right fixed cover through the second heat insulation board 13 .

[0039] A support plate 14 is fixed on the main bracket 101, and the support plate 14 is arranged directly in front of the pressure plate 112. The driver 111 is installed on the support plate 14, and the driver 111 is arranged directly in front of the pressure plate 112. The driving distance of the driver 111 is short, and the push rod of the driver 111 can be made relatively short. A low-power driver 111 can also be used, which greatly reduces the cost of the driver 111 and improves the response time of the pressure plate 112. The pressure plate 112 can be quickly pressed against the heating plate 113.

[0040] A feeding assembly 15 is installed on the frame 10 and is located below the ironing assembly 11. The feeding assembly 15 can pull out the rubber band. The feeding assembly 15 includes a feeding motor 151. A cassette sensing component 16, a material shortage sensing component 17 and a fabric sensing component 18 are installed in sequence below the feeding assembly 15. The material shortage sensing component 17 controls the feeding motor 151 to work when it senses the fabric. The fabric sensing component 18 controls the feeding motor 151 to stop working after sensing the fabric. The rubber band first passes through the material shortage sensing component 17, then passes through the fabric sensing component 18, and finally bypasses the cassette sensing component 16.

[0041] The feeding assembly 15 also includes a feeding driving wheel 152 and a feeding driven wheel 153. The feeding driving wheel 152 and the feeding driven wheel 153 are used for the rubber band to pass through. The feeding driven wheel 153 is arranged in front of the feeding driving wheel 152. The two ends of the pin shaft of the feeding driven wheel 153 are connected to the frame 10 through a tension spring 154.

[0042] Example 2

[0043] The features of Example 2 are basically the same as those of Example 1, except that a threading handle 19 is hinged on the frame 10 to drive the feed driven wheel 153 away from the feed driving wheel 152. The operator can separate the feed driven wheel 153 and the feed driving wheel 152 through the threading handle 19, thereby making it easier for people to pull or handle the rubber band inside.

[0044] Example 3

[0045] The features of Example 3 are basically the same as those of Example 1, except that an anti-rolling plate 20 is fixed on the frame 10 and is located below the feeding active wheel 152. The anti-rolling plate 20 can prevent the rubber band from being wrapped around the feeding active wheel 152, ensuring that the rubber band can be transported downward. The anti-rolling plate 20 is provided with an inclined guide portion 201, which extends upward and close to the discharge position of the feeding active wheel 152. The guide portion 201 is used to guide the rubber band to prevent it from being wrapped around the lower end of the feeding active wheel 152.
