Description

Technical Field

[0001] The present invention mainly relates to the field of trouser pressing machines. Background Art

[0002] A trouser press is a garment machine that uses steam to automatically iron knitted jeans, casual pants, and other items. It works by injecting superheated steam into the trousers, causing them to puff up. The hot steam then expands, coming into contact with the fabric fibers, softening them. The resulting "pulling" and "pressing" action of the steam creates a smooth, even surface. Trouser presses are available in single-station and multi-station models. The multi-station model is described in patent document CN97192551.8. Existing trouser presses, whether single-station or multi-station, do not iron the side seams of the trouser legs. However, these seams are prone to wrinkling due to thread pull and fabric folding. Without ironing, the side seams remain uneven, preventing a perfect ironing effect. Summary of the Invention

DETAILED DESCRIPTION

[0028] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the protection scope of the present invention is not limited to the following embodiments. Any improvements and modifications made to the present invention without departing from the principle of the present invention should be regarded as within the protection scope of the present invention.

[0029] The trouser leg side seam ironing device for a trouser press of the present invention can be applied to a single-station trouser press or a multi-station trouser press, such as Figures 1 to 3The figure shows an example of the present invention being applied to a multi-station trouser press, where trousers are vertically clamped on the trouser press during operation. Figure 4 、 Figure 5 As shown, the present invention comprises two sets of trouser leg clamping and pressing assemblies, a first drive assembly and a second drive assembly. Each set of trouser leg clamping and pressing assemblies comprises two oppositely arranged clamping and pressing heads 1, which are used to clamp the side seams 3 on both sides of a trouser leg to iron the side seams 3 of the trouser leg when the trouser press 18 introduces steam or hot air into the trouser leg to make the trouser leg bulge (see Figure 9 ), so that the side seams 3 of the trouser legs become straight and smooth after ironing. The first driving assembly is used to drive the clamping and ironing heads 1 of the trouser leg clamping and ironing assembly to open or close along the width direction of the trousers 2, and the second driving assembly is used to drive the trouser leg clamping and ironing assembly to move along the length direction of the trousers 2, so that the clamping and ironing heads 1 can move along the seam direction of the trouser leg side seams 3 while ironing, ensuring that the trouser leg side seams 3 are completely and fully ironed.

[0030] See also Figure 6 、 Figure 7 The two clipping ironing heads 1 of each set of trouser leg clipping ironing assembly include an outer clipping ironing head 1a clamped at the outer side seam of the trouser leg and an inner clipping ironing head 1b clamped at the inner side seam of the trouser leg. The first driving assembly includes two parallel synchronous belts 4 and two driving members. Preferably, the two synchronous belts 4 are arranged horizontally, and each driving member drives a corresponding synchronous belt 4 to move. Figure 10 One of the synchronous belts 4 is connected to an outer clip 1a on each side, and the other synchronous belt 4 is connected to an inner clip 1b on each side. By controlling the movement direction and displacement of the two synchronous belts 4, the horizontal position of the clip 1 and the opening and closing degree between the outer clip 1a and the inner clip 1b can be adjusted to accommodate pants 2 of different sizes.

[0031] See also Figures 4 to 7 The driving member is a motor 5 or an air cylinder 6 or an oil cylinder. When the driving member is a motor 5, the motor 5 is connected to the pulley of the timing belt 4. When the driving member is an air cylinder 6 or an oil cylinder, one of the air cylinders 6 or the oil cylinder is connected to an outer clamping ironing head 1a, and the other air cylinder 6 or the oil cylinder is connected to an inner clamping ironing head 1b.

[0032] As the best choice, the driving element is a servo motor 5, which is used to accurately control the displacement of the synchronous belt 4 according to the input signal, thereby achieving precise adjustment of the horizontal position and opening and closing degree of the ironing head 1. When the trouser legs 2 are not straight, but rather have different diameters from top to bottom, the change in the diameter of the trouser legs can be converted into an electrical signal to control the servo motor 5 to move the synchronous belt 4 a corresponding displacement according to the change in the diameter of the trouser legs while the trouser leg ironing assembly moves along the length of the trouser legs 2. This ensures that the horizontal position and opening and closing degree of the ironing head 1 are always adapted to the diameter of the trouser legs, thereby ensuring that the ironing head 1 is always in close contact with the trouser legs throughout the ironing process, thereby ensuring the ironing effect.

[0033] See also Figure 6 、 Figure 7 The working surface of the ironing head 1 is in an inwardly concave arc shape to better fit the surface of the trouser legs.

[0034] See also Figure 10 、 Figure 11 The ironing head 1 is equipped with an ironing steam inlet 7, an ironing steam jet 8, a preheating steam inlet 9, and a preheating steam outlet 10. The ironing steam jet 8 is densely distributed on the working surface of the ironing head 1. The ironing steam inlet 7, preheating steam inlet 9, and preheating steam outlet 10 are located at the bottom of the ironing head 1. The ironing head 1 is internally provided with a preheating steam channel and an ironing steam channel. Passing preheating steam through the ironing head 1 before ironing steam is supplied to the ironing head 1 prevents condensation during ironing, ensuring a good ironing effect.

[0035] See also Figure 11 The ironing head 1 comprises a clamping plate 11, a bracket 12, and a compression spring 13. The clamping plate 11 is the main body of the ironing head 1, used to clamp trouser legs and spray steam for ironing. One end of the clamping plate 11 is hinged to the bracket 12, and the other end is connected to the bracket 12 via a compression spring 13. This structure gives the clamping plate 11 a cushioning effect, allowing it to better adapt to the shape of the trouser legs when clamping, resulting in a better fit.

[0036] See also Figure 4 、 Figure 5 The present invention further includes a mounting frame 14 and a mounting plate 15. The mounting plate 15 is provided with a horizontal guide rail 16. The trouser leg pressing assembly is slidably mounted on the horizontal guide rail 16 via a slider. The mounting frame 14 is provided with a vertical guide rail 17. The mounting plate 15 is slidably mounted on the vertical guide rail 17 via a slider. The provision of the guide rail ensures the smooth movement of the trouser leg pressing assembly.

[0037] See also Figure 8 The second driving assembly includes a vertically arranged synchronous belt 4 and a servo motor 5 for driving the synchronous belt 4, and the mounting plate 15 is connected to the synchronous belt 4.

[0038] See also Figure 2 、 Figure 3 The mounting frame 14 is rotatably connected to the frame 19 of the trouser press 18 and is driven to swing by a swing cylinder 206. When the trousers 2 are not delivered to the station where the trouser leg side seam ironing device is located, the mounting frame 14 swings to Figure 2 The mounting frame 14 is tilted to avoid interference with the delivery of the trousers 2. When the trousers 2 are delivered to the station where the trouser leg side seam ironing device is located, the mounting frame 14 swings to Figure 3 In the vertical state, the servo motor 5 controls the movement of the ironing head 1 to clamp the two sides of the trouser legs and iron the side seams 3 of the trouser legs.
