Description

Technical Field

[0001] This utility model relates to auxiliary devices for the application of elastic bands, and more particularly to a stretching auxiliary device for hot pressing of elastic bands. Background Technology

[0002] Elastic bands are elastic strip-shaped products that are often used in items that require stretching, such as training protective belts or as elastic bands in waistbands.

[0003] For example, combining elastic bands with waistbands can create pants with elasticity, but there are the following disadvantages: if the elastic band and waistband are not sewn together, they will slip; if they are sewn together, positioning is more difficult, and the elasticity of the waistband and waistband cannot be matched. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a stretching auxiliary device for hot pressing of elastic bands, which solves the stretching problem of elastic bands and mating materials. It is suitable for hot pressing sewing equipment for the preparation of elastic waistbands.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a stretching auxiliary device for hot pressing of elastic bands, which is fastened to the hot pressing equipment by a fixed seat. The fixed seat is fixed with a slide rail and a stretching cylinder. There are two sets of sliders that cooperate with the slide rail. The sliders and the stretching cylinders are hinged by a fisheye joint and a connecting rod. The stretching cylinder drives the sliders to reciprocate on the slide rail. A stretching component is fixed on the slider by a support frame. The stretching component is equipped with a pressing component.

[0006] The pressing assembly includes an upper pressing plate, a lower pressing plate, and a pressing cylinder. The pressing cylinder is fixed to the bottom surface of the lower pressing plate by a mounting plate. The top of the piston rod of the pressing cylinder passes through the lower pressing plate and the mounting plate and is connected to the bottom of the upper pressing plate. Four guide rods are also provided. The guide rods pass through the support frame, the pressing cylinder, the mounting plate, and the lower pressing plate in sequence and are connected to the bottom of the upper pressing plate.

[0007] The stretching cylinder and the pressing cylinder are connected to the solenoid valve and the foot switch via air pipes.

[0008] Furthermore, an elastic pad is provided on the upper end face of the upper pressure plate, and an elastic pad is provided between the upper pressure plate and the lower pressure plate.

[0009] Furthermore, a buffer spring is provided on the upper end face of the support frame.

[0010] Furthermore, the slide rail is equipped with a limit device.

[0011] The elastic band and the compound are interlocked by a pressing component. The slider is pulled by a stretching cylinder. At this time, the elastic band and the compound are stretched to the maximum extent and then hot-pressed to form a combination, thus realizing the preparation of the elastic waistband.

[0012] As can be seen from the above description of the structure of this utility model, compared with the prior art, this utility model has the following advantages: it can automatically perform engagement and stretching, and, in conjunction with hot pressing equipment, can prepare elastic waistbands with different elastic coefficients as required.

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] Example

[0016] refer to Figures 1-5 A stretching auxiliary device for hot pressing of elastic bands is fixed to a hot pressing equipment by a fixed base 1. A slide rail 2 and a stretching cylinder 3 are fixed on the fixed base. A slider 4 that cooperates with the slide rail is provided. There are two sets of sliders 4. The sliders 4 and the stretching cylinder 3 are hinged by a fisheye joint 5 and a connecting rod 6. The stretching cylinder 3 drives the sliders 4 to reciprocate on the slide rail 2. A stretching component 8 is fixed on the slider 4 by a support frame 7. The stretching component is provided with a pressing component.

[0017] The pressing assembly includes an upper pressing plate 9, a lower pressing plate 10, and a pressing cylinder 11. The pressing cylinder 11 is fixed to the bottom surface of the lower pressing plate 10 by a mounting plate 12. The top of the piston rod of the pressing cylinder 11 passes through the lower pressing plate 10 and the mounting plate 12 and is connected to the bottom of the upper pressing plate 9. Four guide rods 13 are also provided. The guide rods 13 pass through the support frame, the pressing cylinder, the mounting plate, and the lower pressing plate in sequence and are connected to the bottom of the upper pressing plate.

[0018] An elastic pad 14 is provided on the upper end face of the upper pressure plate, and an elastic pad 14 is provided between the upper pressure plate and the lower pressure plate.

[0019] A buffer spring 15 is provided on the upper end face of the support frame.

[0020] The slide rail is equipped with a limit device 16.

[0021] The stretching cylinder 3 and the pressing cylinder 11 are connected to the solenoid valve and the foot switch via air pipes. When using, install and fix the fixing plate on the hot press equipment, aligning it with the positions of each component.

[0022] The stretching cylinder 3 is driven by the foot switch and the solenoid valve to move the slider 4 on the slide rail 2. The pressing cylinder 11 controls the opening and closing of the upper pressing plate 9 and the lower pressing plate 10. When the pressing cylinder 11 is driven, the lower pressing plate 10 moves downward along the guide rod 13 under the push of the piston rod. The elastic band is clamped by the pressing assembly, and the two sets of stretching assemblies 8 are stretched to both sides by the stretching cylinder 3. After the stretching requirement is met, the hot pressing equipment performs a hot pressing action to heat press the elastic band and the mating material into an elastic waistband. The elastic band is then released by the control of the stretching cylinder 3 and the pressing cylinder 11, and the hot-pressed elastic waistband can be taken out.

[0023] By repeating the above steps, elastic belts with the required elasticity can be produced quickly.
