Compared with the mode that two bottom plates are needed inside and outside a sewing mark and a rear sleeve and materials and the bottom plates need to be taken and replaced in the prior art, a worker only needs to rotate the bottom plates and conduct positioning through three different clamping edges, the working efficiency is greatly improved, the workload of an operator is reduced, skilled personnel are not needed, and the labor intensity of the worker is lowered. A common operator can work, and the quality is stable and is not influenced.

Description

Technical Field

[0001] This utility model relates to the field of shoemaking equipment technology, and in particular to a three-sided positioning sole plate for computer-controlled sewing of shoe uppers. Background Technology

[0002] In the shoe manufacturing process, when using computerized sewing machines to sew large shoe uppers, the sewing range is insufficient, and it is impossible to operate the same computerized sewing machine as the sole plate. This requires multiple material retrievals and template changes, which affects work efficiency. Utility Model Content

[0003] To address the issues of low production efficiency and increased manufacturing costs associated with existing automotive trim stitching methods, this invention provides a three-sided positioning base plate for computer-controlled sewing of shoe uppers.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A three-sided positioning base plate for computer-controlled sewing of shoe uppers includes a base plate with a convex shape. Its three adjacent sides are designated as a first locking side, a second locking side, and a third locking side, each with multiple slots for mounting on a computer sewing machine plate. The base plate has an inner back sleeve slot, an outer back sleeve slot, and a marking slot in the middle, shaped according to the inner and outer heel counters and markings of the shoe upper to be sewn, for the needle to pass through during sewing. Three triangular rotating blocks are also provided on the base plate to hold the shoe upper material in place.

[0006] Compared with the prior art, the beneficial effects of this utility model are as follows: Compared with the prior art, which requires two base plates for sewing markings and inner and outer back covers, and requires materials to be picked up and base plates to be replaced, the workers only need to rotate the base plate and position it through three different locking edges, which greatly improves work efficiency, reduces the workload of operators, does not require skilled personnel, ordinary operators can operate, and the quality is stable and unaffected. Attached Figure Description

[0007] Figure 1 This is a schematic diagram of the main structure of an embodiment of the present utility model.

[0008] In the diagram: 1. Base plate, 101. First locking edge, 102. Second locking edge, 103. Third locking edge, 2. Slot, 3. Rotating locking block, 4. Marking slot, 5. Inner slot of rear sleeve, 6. Outer slot of rear sleeve. Detailed Implementation

[0009] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0011] like Figure 1 As shown, this utility model embodiment includes a base plate 1, which is convex in shape. Its three adjacent sides are a first locking side 101, a second locking side 102, and a third locking side 103, and each side is provided with multiple locking slots 2 for locking and mounting on a computer sewing machine plate. The base plate 1 has an inner back sleeve groove 5, an outer back sleeve groove 6, and a marking groove 4 in the middle according to the inner and outer sides of the shoe upper to be sewn and the markings, for the needle to pass through for sewing. Three rotating locking blocks 3 are provided in a triangular shape on the base plate 1 to hold the shoe upper material.

[0012] First, the upper material is placed on the base plate 1, and the upper material is pressed down by rotating the locking block 3. When marking is to be sewn, the base plate 1 is locked in place with the computerized sewing machine plate through the first locking edge 101; when sewing the inner heel sleeve is to be sewn, the base plate 1 is locked in place with the computerized sewing machine plate through the second locking edge 102; when sewing the outer heel sleeve is to be sewn, the base plate 1 is locked in place with the computerized sewing machine plate through the third locking edge 103. Compared with the existing technology that requires two base plates for sewing markings and the inner and outer heel sleeves, and requires materials to be picked up and the base plates to be changed, the worker only needs to rotate the base plate and position it through three different locking edges, which greatly improves work efficiency, reduces the workload of operators, does not require skilled personnel, ordinary operators can operate, and the quality is stable and unaffected.

[0013] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
