Description

Technical Field

[0001] The utility model relates to a strip wedging machine mouth, in particular to a strip wedging machine mouth used on a strip wedging machine. Background Art

[0002] In the field of shoemaking, sewing a welt along the edge of the sole is a common process. The traditional process is to manually sew the welt around the sole, straighten the welt by hand at the joint of the welt, press the joint with the thumb, and then sew the welt to the sole with a needle. In order to improve the efficiency of sewing, a welt machine is currently used to sew the welt to the sole. However, since the sewing needle of the welt machine moves faster, the joint of the welt cannot be manually straightened and flattened, which makes the needle movement at the joint not smooth, resulting in an uneven joint. Frequent rework reduces work efficiency. Utility Model Content

[0003] In order to solve the above deficiencies in the prior art, the utility model aims to provide a welt machine mouth applied to a welt machine, so as to achieve the purpose of smoothing and flattening the welt while sewing, thereby improving work efficiency.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A welt machine mouth used on a welt machine, comprising a connecting head for pressing the welt onto the sole and a connecting piece for fixing the connecting head on the welt machine;

[0006] The connector includes an upper pressing plate, a lower supporting plate and a baffle, wherein the upper pressing plate and the lower supporting plate are respectively fixed on both sides of the baffle, so that a gap is formed between the upper pressing plate and the lower supporting plate for the sole and the edging to pass through, and the gap is adapted to the sum of the thicknesses of the sole and the edging.

[0007] As another limitation of the present invention, both ends of the upper pressing plate and the lower supporting plate are semicircular.

[0008] As a third limitation of the present utility model, both ends of the upper pressing plate and the lower supporting plate are rectangular, and the right angles are transitioned by arcs.

[0009] As a fourth limitation of the present utility model, a notch for observing the welt joint is provided in the middle of the upper pressing plate.

[0010] As a limitation of the present invention, both ends of the upper pressing plate are inclined surfaces that gradually become thinner from the inside to the outside.

[0011] As a fifth limitation of the present utility model, the connecting member is detachably arranged on the baffle and is a sheet-like structure or a rod-like structure.

[0012] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0013] (1) The utility model fixes the machine mouth on the welt machine and is located in front of the sewing needle in the sewing direction. When the sewing needle is sewing, the joint of the welt will pass through the machine mouth, and the joint is pressed on the sole and is located in the gap between the lower supporting plate and the upper pressing plate. The welt is pressed flatly and firmly on the sole through the gap, and the joint can be smoothed and flattened to prevent the joint from warping and causing the needle to move unsmoothly, thus eliminating the trouble of stopping the machine to adjust the joint before sewing, improving the flatness of the joint connection, and improving work efficiency;

[0014] (2) In the utility model, since the sewing needle of the single-needle sewing machine is relatively long on the sewing track, the semicircular structure at both ends of the connecting head can prevent the sewing needle from colliding with the connecting head when rising from the bottom, thereby preventing the sewing needle from being damaged;

[0015] (3) The rectangular structures at both ends of the connector of the utility model are suitable for double-needle sewing machines. The length of the sewing needle on the sewing track of the welt machine is relatively small. The rectangular structure can increase the length of the sole and the welt clamped, thereby improving the smoothing effect of the connector on the welt.

[0016] (4) The notch on the upper pressing plate of the utility model facilitates observation of the state of the welt joint, and adjustment can be made at any time according to actual conditions to improve the sewing effect;

[0017] (5) The inclined surface on the upper pressing plate of the utility model can guide the joint of the welt to smoothly enter the gap, thereby improving the sewing effect.

[0018] In summary, the utility model can improve the smoothness of the connection at the welt joint, improve the working effect, and is suitable for being installed on a welt machine to sew the welt on the sole. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention, and are not used to limit the present invention.

[0026] Embodiment A strip weaving machine nozzle used in a strip weaving machine

[0027] like Figure 1 , Figure 2 As shown, this embodiment includes a connector 1 and a connector 2. The connector 1 is used to press the welt 4 onto the sole 3 and to smooth and flatten the welt 4 at the connector 1 so that the sewing needle 5 can smoothly pass through the joint of the welt 4. The connector 2 is used to fix the connector 1 on the welt machine.

[0028] The connector 1 comprises an upper pressing plate 11, a lower supporting plate 12 and a blocking plate 13, which are all sheet structures. The upper pressing plate 11 and the lower supporting plate 12 are respectively fixed on both sides of the blocking plate 13 to form a U-shape, so that a gap is formed between the upper pressing plate 11 and the lower supporting plate 12, and the thickness of the gap is adapted to the sum of the thickness of the sole 3 and the welt 4. When in use, the welt 4 is placed on the sole 3, and then the sole 3 and the welt 4 are placed in the gap, so that the connector 1 presses the welt 4 flatly on the sole 3 and straightens the welt 4. When moving to the connector 1, the joint of the welt 4 enters the gap to straighten and flatten it.

[0029] Since the connector 1 is to be installed on the welting machine and used in conjunction with the sewing needle 5 of the welting machine, and is located in front of the sewing movement direction, that is, the connector 1 is used to press the welt 4 onto the sole 3 to smooth and flatten it before the sewing needle 5 sews the welt 4 onto the sole 3, the movement of the connector 1 and the sewing needle 5 need not affect each other. The existing welting machine has two types of sewing needles 5, namely single needles and double needles. The single needle is hook-shaped, and the hook-shaped single needle has a certain length of extension on the sewing track. In order to prevent the sewing needle 5 and the connector 1 from affecting each other, such as Figure 1 As shown, both ends of the upper pressing plate 11 and the lower supporting plate 12 are semicircular, and the semicircular structure can leave a certain space for the sewing needle 5, so that the sewing needle 5 does not collide with the connecting head 1 when moving upward, and prevents it from being deviated after contacting the connecting head 1. Since the double-needle sewing needle 5 has a structure without a hook, the two ends of the connecting head 1 can be as close to the sewing needle 5 as possible, ensuring that the straightened welt 4 can be sewn to the sole 3 in time. Figure 2 As shown, both ends of the upper pressing plate 11 and the lower supporting plate 12 are rectangular, and the right angles are transitioned through arcs.

[0030] A notch 111 for observing the joint of the edge strip 4 is provided in the middle of the upper pressing plate 11. The notch 111 is recessed inward from the edge of the upper pressing plate 11. When the edge strip 4 moves to the position of the connector 1, it is convenient to observe the state of the connector 1 and ensure that the connector 1 of the edge strip 4 is aligned. Figure 3 As shown, both ends of the upper pressing plate 11 are inclined surfaces 112 that gradually become thinner from the inside to the outside, so that the two ends of the upper pressing plate 11 are thinner, which is convenient for guiding the edge strip 4 and preventing the joint of the edge strip 4 from failing to enter the gap between the upper pressing plate 11 and the lower supporting plate 12.

[0031] The connecting member 2 is T-shaped and is detachably connected to the center of the baffle 13 in the length direction by bolts. The connecting member 2 is a sheet-like structure or a rod-like structure. Both the sheet-like structure and the rod-like structure connecting member 2 are provided with through holes and are fixed to the welting machine by bolts. This embodiment is a sheet-like structure.

[0032] When using this embodiment, the connector 1 is fixed to the welting machine through the connector 2 and is located in front of the sewing track of the welting machine needle 5. Figure 3 , Figure 4 As shown, the welt 4 is placed on the sole 3, and then the lower support piece 12 of the connector 1 is pressed against the sole 3, and the upper pressing piece 11 is pressed against the welt 4, so that the sole 3 and the welt 4 are both located in the gap of the connector 1 and have a certain pressure. Then the welt machine is started, and the sole 3 is manually rotated. At this time, the connector 1 first presses the welt 4 tightly on the sole 3, and then the sewing needle 5 passes through the pressed part to sew the welt 4 on the sole 3. When the sewing needle 5 of the welt machine sews along the edge of the sole 3 for nearly a circle and moves to the joint of the welt 4, the joint of the welt 4 enters the gap of the connector 1, and the two ends of the joint are pressed flatly in the gap of the connector 1. As the sole 3 is manually rotated, the joint of the welt reaches the sewing needle 5, and the joint is sewn flat, which reduces the trouble of stopping the machine to manually tidy up the joint and improves work efficiency.

[0033] It should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
