Abstract
Description
Technical Field
[0001] This utility model relates to the field of shoemaking tools, and in particular to a line marker, which is mainly used for drawing lines on the midsole of shoes. Background Technology
[0002] In general shoe manufacturing, the glue application path is first positioned on the midsole, and then the shoe upper forming machine applies glue along the glue application path and bonds the shoe upper to the midsole.
[0003] Currently, the industry standard involves operators measuring and marking the distance between the default glue application position and the edge of the shoe midsole using a ruler. These marked points are then connected online to form a glue application baseline. This method is prone to positional shifts during the online process, resulting in an uneven glue application baseline that requires repeated retracing. This affects the accurate judgment of the actual position of the baseline during glue application, reducing precision. Furthermore, inconsistent standards among operators for drawing the lines lead to deviations in the glue application position within the same batch of shoes, causing glue overflow or unstable bonding during the upper bonding process.
[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content
[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a line drawing device. The device moves by having a base part abut against the edge of the shoe midsole and holding the base to draw a smooth glue-rubbing baseline on the shoe midsole. The drawn lines are smooth and fluid, improving the accuracy of the glue-rubbing baseline drawing position.
[0006] Another objective is to provide a line-drawing tool that can precisely adjust the horizontal distance between the centerline of the drawing pen and the reference section, which can be used to draw shoe midsoles of different sizes.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] A line drawing device, comprising:
[0009] A base for holding by hand;
[0010] Pen holder, used to hold a drawing pen;
[0011] A movable component is disposed on the top of the base and connected to the pen holder to drive the pen holder to move to one side of the base;
[0012] A reference part is provided on the base and located on the same side as the pen holder, for abutting against the edge of the shoe midsole;
[0013] The writing end of the drawing pen is positioned opposite to the reference part, the central axis of the drawing pen is horizontally distanced from the reference part, and the moving component drives the drawing pen to reciprocate on one side of the base to change the horizontal distance.
[0014] As a preferred embodiment, the pen holder has a through-hole for inserting and fixing the drawing pen.
[0015] As a preferred embodiment, the movable component includes a front fixed seat, a rear fixed seat, and a movable shaft. The front fixed seat and the rear fixed seat are positioned opposite each other and spaced apart on the top of the base, each having a through hole for the movable shaft to pass through. The movable shaft passes through the front fixed seat and the rear fixed seat, and its end protruding from the front fixed seat is connected to the rear fixed seat. The movable shaft is driven by an adjusting member to move linearly, thereby changing the horizontal distance between the central axis of the drawing pen and the reference part.
[0016] As a preferred embodiment, the movable shaft has a threaded section and a guide section, the through hole of the front fixed seat has the same shape as the cross-sectional shape of the guide section, and the through hole of the front fixed seat cooperates with the guide section to maintain the linear movement of the movable shaft.
[0017] As a preferred embodiment, the outer peripheral surface of the guide section is provided with a dimensional scale to measure and display the horizontal distance between the central axis of the drawing pen and the reference portion.
[0018] As a preferred embodiment, the adjusting member is disposed between the front fixed seat and the rear fixed seat and is screwed into the threaded section.
[0019] As a preferred embodiment, the reference portion has an upper stop and a lower stop arranged opposite to each other, the upper stop and the lower stop being spaced apart to form a guide groove, which is used to fit onto the edge of the shoe midsole to guide the base to move along the edge of the shoe midsole.
[0020] As a preferred embodiment, the guide groove is provided with an arc-shaped abutment for the edge of the shoe midsole to abut against.
[0021] As a preferred embodiment, the upper stop is provided with a through groove that opens toward the drawing pen, so that the writing end of the drawing pen can move inward into the guide groove.
[0022] As a preferred embodiment, the cross-sectional shape of the guide segment is rectangular or a regular polygon.
[0023] Compared with existing technologies, this invention has significant advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly uses a reference part to abut against the edge of the shoe midsole to locate the drawing position. The gripping base moves the drawing tool, thereby drawing a smooth adhesive-removing baseline on the shoe midsole. The drawn lines are smooth and fluid, improving the accuracy of the adhesive-removing baseline drawing position. Furthermore, the moving component can precisely adjust the horizontal distance between the central axis of the drawing pen and the reference part to adapt to accurately drawing adhesive-removing baselines on shoe midsoles of different sizes.

Detailed Implementation
[0031] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of an embodiment of the present invention.
[0032] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", 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.
[0033] A line-drawing device includes a base 1, a pen holder 2, a moving component 3, and a reference part 4. The base 1 is for hand gripping. The moving component 3 is located on the top of the base 1 and connected to the pen holder 2 to drive the pen holder 2 to move to one side of the base 1. The reference part 4 is located on the base 1 and on the same side as the pen holder 2, and abuts against the edge 51 of the shoe midsole 5. The pen holder 2 has a through-hole 21 for inserting and fixing the line-drawing pen 5. The writing end 51 of the line-drawing pen 5 is opposite to the reference part 4, and there is a horizontal distance T between the central axis Z of the line-drawing pen 5 and the reference part 4, for drawing a rubber-applied baseline L on the shoe midsole.
[0034] To further explain, such as Figure 1 and Figure 2 As shown, the movable component 3 includes a front fixed seat 31, a rear fixed seat 32, and a movable shaft 33. The front fixed seat 31 and the rear fixed seat 32 are positioned opposite each other and spaced apart on the top of the base 1, each having a through hole 311 and 321 for the movable shaft 33 to pass through. The movable shaft 33 has a guide section 331 and a threaded section 332. The threaded section 332 extends from the through hole 311 of the front fixed seat 31 and passes through the through hole 321 of the rear fixed seat 32. The guide section 331 is connected to the pen holder 2 at its end extending from the front fixed seat 31. An adjusting member 34 is provided between the front fixed seat 31 and the rear fixed seat 32, and the adjusting member 34 is screwed onto the threaded section 332. In this embodiment, the adjusting member 34 is preferably a knob with internal threads, which is sleeved on the moving shaft 33 and screwed into the threaded section 332. Rotating the adjusting member 34 causes the moving shaft 33 to move horizontally.
[0035] Among them, such as Figure 2As shown, the cross-sectional shape of the guide section 331 is a regular polygon, and the shape of the through hole 311 of the front fixed seat 31 is the same as the cross-sectional shape of the guide section 331. The guide section 331 cooperates with the through hole 311 of the front fixed seat 31, preventing the moving shaft 33 from rotating within the front fixed seat 31 and the rear fixed seat 32, ensuring that the moving shaft 33 maintains linear movement when driven by the adjusting member 34. The cross-sectional shape of the guide section 331 is rectangular or a regular polygon, including equilateral triangles, squares, pentagons, and hexagons. In this embodiment, the cross-sectional shape of the guide section 331 is square, and the shape of the through hole 311 of the front fixed seat 31 is also square.
[0036] Next, as Figure 2 and Figure 3 As shown, the reference part 4 is preferably located at the bottom of the base 1 and on the same side as the pen holder 2. The reference part 4 has an upper stop 41 and a lower stop 42 arranged opposite each other, and the upper stop 41 and the lower stop 42 are spaced apart to form a guide groove 43. An arc-shaped abutment part 44 is provided in the guide groove 43.
[0037] When drawing, such as Figure 4 and Figure 5 As shown, the guide groove 43 is fitted onto the edge 61 of the shoe midsole 6, and the abutment part 44 abuts against the edge 61 of the shoe midsole 6, ensuring that the vertical distance between any drawing point and the edge 61 remains consistent. Because the edge of the shoe midsole 6 is curved, the contact area between the arc-shaped abutment part 44 and the edge 61 of the shoe midsole 6 is small, reducing the friction between the base 1 and the shoe midsole 6 as it moves. This allows the base 1 to smoothly conform to the edge 61 of the shoe midsole 6 without forming gaps at the bend, ensuring that the vertical distance between any drawing point of the adhesive application baseline and the edge of the shoe midsole remains consistent, thus achieving the effect of accurately drawing the adhesive application baseline.
[0038] To facilitate users in quickly adjusting the indentation of the adhesive removal baseline, such as Figure 2 and Figure 4As shown, the outer circumferential surface of the guide section 331 is also provided with a size scale 333. By reading the length indicated by the size scale 333 between the pen holder 2 and the front fixed seat 31, the horizontal distance T between the central axis Z of the drawing pen 5 and the reference part 4 can be measured. This horizontal distance T is consistent with the inward amount W of the glue-wiping baseline L drawn on the shoe midsole 6. It should be noted that the length D indicated by the size scale 333 of the guide section 331 is the horizontal distance T between the central axis Z of the drawing pen 5 and the outer side of the abutment part 44. Therefore, when using it, the operator can rotate the adjusting member 34 to move the moving shaft 33 according to the inward amount W, and adjust it until the length D indicated by the size scale 333 is consistent with the preset inward amount W. This allows for convenient and accurate adjustment of the inward amount W, meeting the needs of drawing the glue-wiping baseline L on shoe midsoles of different sizes and shapes.
[0039] To further explain, such as Figure 1 and Figure 3 As shown, the upper stop 41 is provided with a through groove 411 with an opening facing the drawing pen 5, so that the writing end 51 of the drawing pen 5 can move inward along the through groove 411 into the guide groove 43, so that the drawing pen 5 can draw the glue-wiping baseline L with a smaller inward shrinkage W, which meets the inward shrinkage requirements for drawing the glue-wiping baseline of shoe midsoles of different sizes.
[0040] For practical application of this utility model, please refer to [link / reference]. Figure 4 and Figure 5 Take a shoe midsole 6 and calculate the inward reduction W of the glue-applying baseline L based on the size of the shoe midsole 6. The inward reduction W refers to the vertical distance between any point on the shoe midsole where the glue-applying baseline L is drawn and the edge 61 of the shoe midsole 6. Rotate the adjusting member 34 according to the inward reduction W until the length D read by the size scale 333 matches the inward reduction W, that is, the horizontal distance T between the central axis Z of the drawing pen 5 and the outer side of the abutment part 44 matches the inward reduction W. Then, fit the guide groove 43 of the reference part 4 onto the edge 61 of the shoe midsole 6, with the abutment part 44 abutting against the edge 61 of the shoe midsole 6, and adjust the writing end 51 of the drawing pen 5 to contact the surface of the shoe midsole 6. Finally, hold the base 1 and move it along the edge 61 of the shoe midsole 6, maintaining contact between the abutment part 44 and the edge 61 of the shoe midsole 6, to draw the glue-applying baseline L of the required length on the shoe midsole 6.
[0041] The key design feature of this invention is that the reference part is fitted onto the edge of the shoe midsole, and the abutting part abuts against the edge of the shoe midsole. This ensures that the distance between the writing end of the drawing pen and the edge of the shoe midsole remains consistent during drawing, achieving the effect of accurately drawing the adhesive application baseline. Secondly, the drawing position of the adhesive application baseline can be flexibly changed. The drawing pen abuts against the edge of the shoe midsole with the reference part, and the moving component adjusts the distance between the drawing pen and the reference part to change the amount of indentation in the drawing, thereby meeting the adhesive application baseline drawing requirements of different shoe midsoles and heels.
[0042] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
