Description

Technical Field

[0001] The utility model belongs to the technical field of shoemaking templates, and in particular relates to a block-type variable-thickness automatic sewing template. Background Art

[0002] Chinese patent application number 202322576356.7 discloses an automated sewing template for preventing seam displacement in footwear. The template comprises a base plate 1, a bottom outer contour plate 2, and a middle seam outer contour plate 3. A stitching groove 11 is provided in the center of the base plate 1, a seam bottom outer contour 21 is provided in the center of the bottom outer contour plate 2, and a seam bottom outer contour 31 is provided in the center of the middle seam outer contour plate 3 to mate with the seam bottom outer contour 21. The seam bottom outer contour 21 is essentially a receiving groove cut into the bottom outer contour 21 by the bottom outer contour plate 2. The middle seam outer contour plate 3 presses against the bottom outer contour plate 2 and the upper material to be sewn, preventing the upper material from shifting. However, since the bottom outer contour plate 2 has a fixed thickness, while the materials and thicknesses of uppers used in shoemaking vary, the aforementioned sewing template is not suitable for thicker or thinner materials. If the upper material is too thin compared to the thickness of the bottom outer contour plate 2, it will not be pressed tightly. If the upper material is too thick, the material will be squeezed and deformed, often resulting in sewing line deviation and uneven stitch length, further increasing the difficulty and cost of sewing. In addition, hollowing out the bottom outer contour plate to form an embedded receiving groove wastes the material. Summary of the Invention

[0003] Aiming at the problem that the traditional sewing templates in the prior art cannot adapt to materials of different thicknesses, resulting in unsatisfactory sewing effects and even affecting the appearance and quality of shoes, the utility model provides a block-type variable thickness automatic sewing template.

[0004] The purpose of this utility model is achieved in the following ways:

[0005] A card block type variable thickness automatic sewing template includes a base plate and a cover plate which are hinged to each other. A first sewing groove is provided on the base plate, and a second sewing groove adapted to the first sewing groove is provided on the cover plate. A variable thickness limit card block is installed on the base plate, and the limit card block positions the shoe material on the base plate. A limit card block accommodating groove is provided on the cover plate.

[0006] A limit card block replacement block having the same shape as the limit card block is inserted on the upper surface of the limit card block.

[0007] The upper surface of the limit card block is provided with a positioning hole, and the lower surface of the limit card block replacement block is provided with a positioning protrusion, or the upper surface of the limit card block is provided with a positioning protrusion, and the lower surface of the limit card block replacement block is provided with a positioning hole, and the positioning hole matches the positioning protrusion.

[0008] The upper surface of the limit card block is provided with a positioning hole or a positioning protrusion. The limit card block replacement block has a positioning protrusion on one side and a positioning hole on the other side. The positioning hole matches the positioning protrusion.

[0009] There are three positioning holes and positioning protrusions.

[0010] The shoe material is a shoe upper, and the limiting block includes a first limiting block and a second limiting block. The first limiting block is adapted to the shape of the front tip of the shoe upper, and the second limiting block is adapted to the shape of the opening of the shoe upper where the tongue is to be installed.

[0011] The bottom plate and / or the cover plate are both provided with positive and negative marking blocks.

[0012] Compared with the prior art, the present invention replaces the existing accommodating slot limit with a limit block limit, because the precise matching of the limit block reduces the unnecessary cutting of the sewing template material, reduces the waste of the plate, and saves costs; by superimposing multiple layers of limit blocks, the thickness of the limit blocks can be changed, thereby adapting to shoe materials of different thicknesses, adapting to new sewing requirements, and improving sewing efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. After reading the contents of the present invention, those skilled in the art may make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present invention.

[0015] like Figure 1 As shown, a block-type variable thickness automatic sewing template includes a base plate 1 and a cover plate 2 that are hinged to each other, a first sewing groove 11 is provided on the base plate 1, and a second sewing groove 21 adapted to the first sewing groove 11 is provided on the cover plate 2. A variable thickness limiting block 3 is installed on the base plate 1, and the limiting block 3 positions the shoe material on the base plate 1. A limiting block accommodating groove 22 is provided on the cover plate 2.

[0016] The thickness change of the limiting block 3 is achieved by inserting a limiting block replacement block (not shown in the figure) with the same shape as the limiting block 3 on the upper surface of the limiting block 3. The specific implementation form is: the upper surface of the limiting block 3 is provided with a positioning hole, and the lower surface of the limiting block replacement block is provided with a positioning protrusion matched with the positioning hole; or, the upper surface of the limiting block 3 is provided with a positioning protrusion, and the lower surface of the limiting block replacement block is provided with a positioning hole matched with the positioning protrusion; different thicknesses of limiting block replacement blocks are selected, and the limiting block 3 is connected through the positioning protrusion and the positioning hole to adapt to shoe materials of different thicknesses. Alternatively, the upper surface of the limiting block 3 is provided with a positioning hole or a positioning protrusion, one of the upper and lower surfaces of the limiting block replacement block is provided with a positioning protrusion, and the other is provided with a positioning hole, and the positioning hole and the positioning protrusion are matched, and the upper surface of the limiting block 3 can be stacked with multiple limiting block replacement blocks until the thickness of the shoe material to be sewn is met.

[0017] The limiting block 3 is stacked in multiple layers through the positioning hole and the positioning protrusion structure to adjust the thickness of the limiting block 3 to adapt to shoe materials of different thicknesses, solve the problem of sharing of spring and autumn shoes and summer shoes with different thicknesses, ensure the accuracy and repeatability in the sewing process, and reduce the sewing deviation caused by the change of material thickness.

[0018] The existing accommodating groove limiting is replaced by the limiting block, because the accurate matching of the limiting block reduces the excess cutting of the material, reduces the waste of the plate, saves the cost; by stacking multiple limiting blocks, the height of the limiting block is changed to adapt to shoe materials of different thicknesses to meet the new sewing requirements and improve the sewing efficiency.

[0019] In order to connect the limiting block 3 and the limiting block replacement block firmly and prevent deviation, the positioning hole and the positioning protrusion each have three.

[0020] As shown in Figure 1 The shoe material to be sewn is a shoe upper piece 4, a limiting block type variable thickness automatic sewing template, comprising a bottom plate 1 and a cover plate 2 hingedly connected to each other, the bottom plate 1 is provided with a first sewing groove 11, the cover plate 2 is provided with a second sewing groove 21 matched with the sewing groove 11, the bottom plate 1 is provided with a variable thickness limiting block 3, the limiting block 3 comprises a first limiting block 31 and a second limiting block 32, the first limiting block 31 is matched with the shape of the front tip of the shoe upper piece, the second limiting block 32 is matched with the shape of the port door of the shoe upper piece to be installed with a tongue, the first limiting block 31 and the second limiting block 32 position the shoe upper piece, the limiting block 3 positions the shoe material on the bottom plate 1, and the cover plate 2 is provided with a limiting block accommodating groove 22. The shoe upper piece is clamped between the first limiting block 31 and the second limiting block 32, the cover plate 2 is covered, the shoe upper piece 4 is pressed tightly, and then a pattern machine and performance can be used for sewing.

[0021] Furthermore, positioning holes 33 are provided on the first limit block 31 and the second limit block 32, and positioning protrusions are provided on the lower surfaces of the limit block replacement blocks that are the same shape as the first limit block 31 and the second limit block 32, respectively. The limit block replacement blocks are respectively inserted into the first limit block 31 and the second limit block 32 to increase the height of the two limit blocks to adapt to shoe uppers of different thicknesses.

[0022] The limiting card block accommodating groove 22 on the cover plate 2 has the same shape as the limiting card block 3 , and the groove width is slightly larger than the width of the limiting card block 3 , preferably with a difference of 5 mm, so that the limiting card block 3 can pass through the limiting card block accommodating groove 22 .

[0023] The limited card block design is better than the original accommodating slot design because the precise matching of the limited card block reduces the redundant cutting of sewing template materials and reduces the waste of plates. The original template requires 50cm 2 , after the change only 25cm 2 , saving 50% of the cost; by superimposing multiple layers of limit blocks, the thickness of the limit blocks can be changed, thereby adapting to shoe materials of different thicknesses to meet new sewing requirements and improving sewing efficiency.

[0024] According to the stress conditions, retain the outer contour and offset lines in the sewing corner area where the stress is greater. Interrupt the lines at a stable position to facilitate the corresponding position of the upper layer. Offset the opening by 0.5mm according to the interrupted line and perfectly snap it into the slot. This is the method of removing the slot, generally at the corner because the stress is the greatest at the corner during sewing.

[0025] The bottom plate 1 and / or the cover plate 2 are both provided with triangular front and back marking blocks 5, which are used to distinguish the front and back sides of the template, so as to facilitate assembly and distinguish the left and right feet of the shoe.

[0026] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the scope of protection of the present invention.
