Description

TECHNICAL FIELD

[0001] The utility model relates to the field of edge covering hawk's beak, especially to an edge covering hawk's beak with fixing structure for sewing machine. BACKGROUND

[0002] In the garment processing, textile manufacturing and other industries, sewing machine is one of the key equipment, and the edge covering process is a common and important process. The traditional sewing machine edge covering device has many deficiencies when processing edge covering of thin cloth strips.

[0003] In the thin cloth strip conveying link, edge covering hawk's beak is generally used to assist in conveying, but the mouth inlet at the front position of the edge covering hawk's beak lacks effective width self-adaptive limiting, and it is difficult to accurately position the thin cloth strips of different widths, which often leads to deviation of the thin cloth strips during conveying, which not only reduces the accuracy of edge covering, but also easily causes uneven edge covering, size deviation and other quality problems, and also affects the smoothness of the entire production process, increases the rate of defective products and rework rate, and increases the production cost and time cost. Moreover, when the thin cloth strip is placed and installed, the mouth specification is relatively small, making the threading process of the thin cloth strip more troublesome and time-consuming, which seriously restricts the production efficiency and cannot meet the needs of modern large-scale and high-efficiency production.

[0004] Therefore, it is necessary to provide a new edge covering hawk's beak with fixing structure for sewing machine to solve the above technical problems. CONTENT OF THE UTILITY MODEL

[0005] To solve the above technical problems, the utility model provides an edge covering hawk's beak with fixing structure for sewing machine.

[0013] Compared with related technologies, the edging beak with a fixed structure for sewing machines provided by this utility model has the following beneficial effects:

[0014] 1. This utility model drives the adjustment shaft to rotate by rotating the handle, which in turn drives the two adjustment blocks to slide relative to the two side walls of the bottom cover. This causes the two limiting side plates to move and abut against the two sides of the thin fabric strip. The two limiting side plates can limit the thin fabric strips of different widths, effectively limiting the thin fabric strips of different widths and ensuring that the thin fabric strips are stably and non-deviationly conveyed in the front shell. This improves the accuracy and stability of the edging operation and helps to improve the processing quality of the product.

[0015] 2. This utility model, by overlapping the top cover and the bottom cover, allows the inserts on the two locking blocks to slide into the slots in the two alignment blocks respectively, and one end of the two locking rods to automatically slide into the two grooves. This enables the front shell to be assembled quickly after the fine fabric strip is installed, significantly saving the time of installing the fine fabric strip, greatly improving work efficiency, and providing strong support for the efficient development of sewing machine edge binding operations.

[0024] It should be noted that: rotating the handle 54 drives the adjusting shaft 53 to rotate, drives the two limiting side plates 4 to move to abut on the two sides of the narrow cloth strip, and the two limiting side plates 4 can be used to limit the narrow cloth strip of different widths, so that the narrow cloth strip can be stably conveyed in the front shell 3 without deviation.

[0025] Referring to Figure 3 The two ends of the bottom shell 52 are symmetrically provided with open grooves, and the lower ends of the two adjusting blocks 51 are slidably connected with the two open grooves respectively.

[0026] It should be noted that: the lower ends of the two adjusting blocks 51 are slidably connected with the two open grooves respectively, so that the moving direction of the two adjusting blocks 51 can be limited.

[0027] Referring to Figure 1 and Figure 3 As shown in the figure, the lower end of each of the two adjusting blocks 51 is provided with a screw, and the two ends of the adjusting shaft 53 are symmetrically provided with threads in opposite directions, and the two screws are respectively threadedly connected with the two ends of the adjusting shaft 53.

[0028] It should be noted that the rotation of the handle 54 drives the adjusting shaft 53 to rotate, and drives the two adjusting blocks 51 to drive the two slide rods 5 to slide relative to the two side walls of the bottom cover 31.

[0029] Referring to Figure 1 and Figure 2 As shown in the figure, the two side walls of the upper cover 32 are each provided with a clamping block 6, and the two clamping blocks 6 are each provided with an insert, and the two side walls of the bottom cover 31 are each provided with an alignment block 61, and the two alignment blocks 61 are each provided with a clamping hole, and the two clamping blocks 6 are respectively arranged in alignment with the two alignment blocks 61.

[0030] It should be noted that the upper cover 32 is overlapped with the bottom cover 31, and the inserts on the two clamping blocks 6 are respectively slid into the clamping holes in the two alignment blocks 61, so that the assembly of the front shell 3 can be quickly completed after the installation of the fine cloth strip is completed, effectively saving the time for installing the fine cloth strip, and bringing convenience to the installation of the fine cloth strip.

[0031] Referring to Figure 2 and Figure 4 As shown in the figure, the two inserts are each provided with a groove, the two alignment blocks 61 are each provided with a cavity, one end of the two cavities is respectively communicated with the two clamping holes, and the two cavities are each provided with an inserting assembly.

[0034] At the same time, pulling the two pinch pieces 8 drives the two clamping rods 71 to retract relative to the two side pipes 7, so that the two springs 72 are elastically deformed, and when one end of the two clamping rods 71 is respectively slid out of the two grooves, the locking of the two inserts is released.

[0035] The working principle of the edge covering eagle beak with the fixing structure for the sewing machine is as follows: the thin cloth strip is placed in the bottom cover 31, the handle 54 is rotated to drive the adjusting shaft 53 to rotate, the two adjusting blocks 51 are driven to slide the two slide rods 5 relative to the two side walls of the bottom cover 31, the two limiting side plates 4 are driven to move to abut against the two sides of the thin cloth strip, the two limiting side plates 4 can limit the thin cloth strips with different widths, so that the thin cloth strip can be stably conveyed in the front shell 3 without deviation.

[0036] When the upper cover 32 is overlapped with the bottom cover 31, the two inserts on the two clamping blocks 6 are respectively slid into the clamping holes in the two alignment blocks 61, when the two inserts abut against the inclined surfaces at one end of the two clamping rods 71, the two springs 72 are elastically deformed, until the two clamping rods 71 are overlapped with the two recesses, the two springs 72 restore the elastic deformation, so that one end of the two clamping rods 71 is respectively slid into the two recesses, the assembly of the front shell 3 can be quickly completed after the thin cloth strip is installed, the time for installing the thin cloth strip is effectively saved, and the installation of the thin cloth strip is facilitated.
