Description

[0002] The sofa fabric will go through many steps during the processing. The surface of the initially processed fabric will have a lot of wrinkles, which need to be shaped by a shaping mechanism. Conventional shaping structures use hot steam to iron the fabric to achieve a wrinkle removal effect.

[0003] In the prior art, a Chinese patent document with publication number CN211471822U proposes a shaping mechanism for sofa fabrics, which can adjust the size of the steam chamber according to the width of the fabric. After the steam generated by the steam device enters the steam chamber, it is discharged through the air outlet and directly sprayed on the fabric for shaping. No excess steam will be sprayed outside the fabric, thereby saving energy.

[0004] However, in actual use of the above device, it was found that due to the fixed position of the nozzle, the wetting degree on the fabric was different, which in turn affected the overall shaping effect of the sofa fabric. Therefore, we made improvements to this and proposed a shaping method and device for sofa fabric. Summary of the invention

[0054] See also Figures 1 to 6 The present invention provides a technical solution: a shaping device for sofa fabrics, comprising a shaping chamber 1 and an input end 10 and an output end 11 respectively formed at both ends of the shaping chamber 1 for the passage of the sofa fabric 12 to be shaped, and two sets of relatively parallel shaping structures 2 are arranged in the shaping chamber 1 for high-temperature steam shaping of the sofa fabric 12, and also comprising;

[0055] A reciprocating structure 3 is provided between two sets of shaping structures 2; a driving structure 4 is provided at the top of the shaping bin 1 and is used to drive the reciprocating structure 3 to swing, so that the two sets of shaping structures 2 swing back and forth alternately to form a comprehensive steam shaping of the sofa fabric 12; an auxiliary structure 5 is provided on one side of the shaping structure 2 and is used to tighten the sofa fabric 12 during the conveying process; the shaping structure 2 includes an upper steam pipe 20 and a lower steam pipe 21, both ends of the upper steam pipe 20 and the lower steam pipe 21 are fixed with spring telescopic support rods 22, and both ends of the upper steam pipe 20 and the lower steam pipe 21 are also connected with a chamfered pipe 24 near the spring telescopic support rod 22, wherein one end of the two spring telescopic support rods 22 on the same side are fixedly connected with a supporting side plate 23;

[0056] The spring telescopic support rod 22 can be adjusted in length and can be slid and reset without external force. The two ends of the support side plate 23 are connected to the positions of the chamfered tube 1 24. A transmission rope 26 is passed through the support side plate 23, and the two free ends of the transmission rope 26 pass through the outside of the corresponding chamfered tube 25 and are fixedly connected to the corresponding chamfered tube 1 24. The transmission rope 26 is in a tensioned state. The middle parts of the upper steam pipe 20 and the lower steam pipe 21 are connected to a steam delivery pipe 27 for connecting to an external steam generating device.

[0057] The upper steam pipe 20 and the lower steam pipe 21 are connected to opposite sides thereof with steam nozzles 28. A plurality of steam nozzles 28 are arranged at equal intervals on the upper steam pipe 20 and the lower steam pipe 21 and are connected to the inside thereof, so as to eject the steam inputted into the steam delivery pipe 27. The steam delivery pipe 27 has a reserved portion of a certain length inside the shaping chamber 1. The reserved length of the steam delivery pipe 27 can satisfy the movement of the upper steam pipe 20 and the lower steam pipe 21 when they swing back and forth.

[0058] like Figure 1 As shown, the sofa fabric to be shaped is input into the shaping chamber 1 through the input end 10, passes through the auxiliary structure 5, the shaping structure and the auxiliary structure 5 in sequence, and finally extends to the outside of the shaping chamber 1 through the output end 11. In the actual shaping process, the steam with a certain pressure is transported into the steam conveying pipe 27 through the external steam generating device and input into the corresponding upper steam pipe 20 and lower steam pipe 21. The steam inside will eventually be sprayed out through the steam nozzle 28, thereby forming a spray shaping of the sofa fabric inside.

[0059] During the actual spraying process, the steam nozzle 28 is driven by the driving structure 4 to synchronously drive the reciprocating structure 3 to reciprocate, thereby driving the upper steam pipe 20 and the lower steam pipe 21 to move synchronously, thereby forming a more uniform steam spraying shaping on the surface of the sofa fabric.

[0060] The reciprocating structure 3 includes an incomplete gear 30 and a tooth plate 1 31 and a tooth plate 2 32 meshed with both sides of the incomplete gear 30, wherein the tooth plate 1 31 and the tooth plate 2 32 are respectively fixedly matched with the corresponding upper steam pipe 20;

[0061] The driving structure 4 includes a mounting frame 41 connected to the top wall of the shaping bin 1 for mounting a servo motor 40, and a driving shaft 42 at the output end of the servo motor 40 is coaxially fixedly assembled with the corresponding incomplete gear 30 below;

[0062] Specifically, the servo motor 40 is started to drive the driving shaft 42 thereon and the incomplete gear 30 connected thereto to move. Through the rotation of the incomplete gear 30, the tooth plate 1 31 and the tooth plate 2 32 corresponding to the upper steam pipe 20 and the lower steam pipe 21 on the outer side thereof are intermittently meshed. The tooth plate 1 31 and the tooth plate 2 32 meshed will synchronously drive the upper steam pipe 20 thereon to move, so as to form a reciprocating swinging action of the two upper steam pipes 20.

[0063] Through the movement of the upper steam pipe 20, the lower steam pipe 21 can be synchronously driven to move through the action of the transmission rope 26, and during the meshing movement of the gap, when the incomplete gear 30 does not mesh with the corresponding tooth plate 1 31 or the tooth plate 2 32, it can be moved and reset under the action of the spring telescopic support rod 22 to wait for the meshing action with the incomplete gear 30 to be formed again.

[0064] A guide structure is also provided inside the chamfered tube 25 for rolling and guiding the transmission rope 26;

[0065] The guide structure includes two upper and lower guide wheels 250 that are relatively arranged. A support shaft 251 is fixed on the two guide wheels 250 for rotationally connecting with the side wall of the chamfered tube 25. Guide groove surfaces 252 are formed on the inner sides of the two guide wheels 250. A guide space 253 is formed between the two guide groove surfaces 252 for the transmission rope 26 to pass through. During the transmission movement of the above-mentioned transmission rope 26, the transmission rope 26 in the sliding process is affected by the guide wheels 250 and can slide better, thereby reducing the friction during the sliding process, which is beneficial to the protection of the transmission rope 26 itself.

[0066] The auxiliary structure 5 includes two conveying rollers 50 arranged in parallel up and down, and both ends of the two conveying rollers 50 are movably connected to the side wall of the shaping bin 1 through an axle seat, wherein a tensioning roller 52 is also provided on one side of the conveying roller 50, and both ends of the tensioning roller 52 are connected to the top wall of the shaping bin 1 through a support member, and the support member includes a support seat 53 for movably assembling the tensioning roller 52 and its internal structure and a support column 54 connected to the top wall of the shaping bin 1, and a spring telescopic column 55 is commonly connected between the support column 54 and the support seat 53, so that the sofa fabric can be conveyed before and after, and the position can be guided by the conveying roller 50, and the elastic force of the spring telescopic column 55 can be cooperated to keep the surface of the sofa fabric in a tensioned state, so that the gap between the fabrics on the sofa fabric 12 is completely opened, so that the steam can better contact it, forming a subsequent shaping effect.

[0067] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
