Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for garment production, and in particular to a continuous positioning dot tool for custom shirts. Background Technology

[0002] In the current production process of custom shirts, due to the increasing demand for personalization from consumers, each shirt varies significantly in terms of length, pattern, and the number of hem marking points (usually 6 to 8). This highly non-standardized production characteristic poses a serious challenge to traditional manufacturing processes. Existing production models generally rely on manual operation: employees must first check the length parameters corresponding to the order, match the appropriate pattern, and then manually mark the hem marking points one by one. This process is not only cumbersome and inefficient—marking points on a single shirt takes at least 51 seconds—but is also highly susceptible to human error. For example, visual judgment errors, operator fatigue, or distraction often lead to quality problems such as misaligned marking points and uneven spacing, seriously affecting product consistency and customer satisfaction. More importantly, there is currently a lack of dedicated automated equipment on the market for marking hem marking points on custom shirts; general-purpose marking devices cannot flexibly adapt to multiple garment lengths and variable number of marking points, making it difficult to meet the needs of small-batch, highly variable personalized production.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] A continuous positioning dotting tool for custom shirts includes a suction table 2, a workpiece mold 3, an air-jetting device, and a needle-laying device.

[0032] The upper surface of the suction table 2 is a fabric laying area 21, which is used to absorb and fix the fabric laid on its surface during the operation.

[0033] The needle-laying device includes a needle-laying assembly 43 and a needle-laying connecting bracket 4; the needle-laying connecting bracket 4 includes a fixed frame 41 and a movable crossbeam 42 that can move up and down relative to the fixed frame 41; the needle-laying assembly 43 is fixedly connected to the needle-laying holes on the movable crossbeam 42; the movable crossbeam 42 is arranged below the laying mold.

[0034] The laying mold 3 includes a support plate and a positioning plate; the positioning plate is installed on the support plate and a gap is reserved between the positioning plate and the support plate.

[0035] The support plate is installed on the edge of the suction table, and the upper surface of the fabric laying mold 3 is flush with the fabric laying area 21.

[0036] The positioning plate includes a first positioning mold 31, a second positioning mold 32 and a third positioning mold 33; a positioning groove 34 is formed between adjacent positioning molds; a plurality of mold positioning pin holes 10 are spaced apart on the support plate.

[0037] The air-pumping device is connected to the pin header connecting bracket 4, with one end fixedly connected to the fixed frame 41 and the other end abutting against the moving crossbeam 42; thereby driving the pin header assembly 43 on the moving crossbeam 42 to move up and down.

[0038] The mold positioning pin hole 10 is aligned with the needle array 43, so that when the needle array 43 moves upward, the needle ends penetrate the mold positioning pin hole 10 and form a stop point on the fabric located within the reserved gap. In this embodiment, the positioning pressure plate has a bent portion, which is vertically installed on the support plate by fixing screws 11, so that the positioning pressure plate is vertically fixed to the support plate and a reserved gap is formed between it and the support plate for embedding the fabric.

[0039] During operation, depending on the required garment length and number of stop points in the order, the fabric can be extended into the positioning groove 34 formed between adjacent positioning molds to avoid positions where punching is not required.

[0040] The fixed frame 41 is connected to the air-pumping device, and the movable crossbeam 42 can move vertically on the fixed frame 41. Specifically, the fixed frame 41 is provided with a vertical guide rail; the movable crossbeam 42 has corresponding sliders at both ends, which slide and engage with the guide rail, so that the movable crossbeam 42 can slide in the vertical direction while maintaining lateral stability.

[0041] When the air-punching device is activated, it drives the moving beam 42 to move upward, causing the needle array 43 to rise synchronously. The ends of the needles pass through the mold positioning pin holes 10, forming the required stop points on the fixed fabric. After punching is completed, the air-punching device resets, and the moving beam 42 and needle array 43 return to their initial positions, ready for the next operation.

[0042] Furthermore, the first positioning mold 31, the second positioning mold 32, and the third positioning mold 33 are integrally formed; the first positioning mold 31 and the second positioning mold 32 are each provided with a mold positioning pinhole 10; the third positioning mold 33 is provided with six mold positioning pinholes 10. By pre-setting different numbers of mold positioning pinholes 10 on different positioning molds, they can be flexibly combined and used. In this embodiment, using only the third positioning mold 33 is suitable for orders with six-point positioning for short garments, while using all molds simultaneously meets the requirements for eight-point positioning for long garments, improving the versatility of the equipment.

[0043] Furthermore, the reserved gap design can accommodate fabric edges with a thickness ranging from 0.1 to 0.2 cm, which not only facilitates the embedding of the fabric edge but also serves as a guard structure to effectively limit the displacement of the fabric during operation, ensuring the accuracy and stability of the positioning.

[0044] Furthermore, such as Figure 4 As shown, the fabric laying mold 3 is provided with a collar bottom positioning reference line 9 with scale markings; the operator can align the bottom of the shirt collar with the reference line and calibrate the fabric position in conjunction with the mold positioning pinhole 10, thereby achieving precise positioning of the fabric.

[0045] Furthermore, the needle holes on the needle row connecting bracket 4 are arranged at equal intervals; the distance between the first needle of the needle row group 43 and the positioning reference line of the lower collar seat is L; the distance between the remaining adjacent needle rows is H; where L is 5 cm and H is 9 cm. This equidistant needle row layout, combined with the precisely set L (5 cm) and H (9 cm) dimensions, ensures that the position of the stop point is uniform and the spacing is consistent, effectively matching the common garment length specifications of customized shirts; during operation, it is only necessary to align with the reference line of the lower collar seat 12 to automatically achieve accurate positioning of all sequence points, avoiding manual measurement errors and improving dotting efficiency and product consistency.

[0046] Furthermore, the air-cushioning device includes a miniature cylinder 5, a piston rod 6, a solenoid valve 8, and a foot switch 7; the output end of the foot switch 7 is electrically connected to the control end of the solenoid valve 8, and is used to send a trigger signal to the solenoid valve 8 when the foot is stepped on.

[0047] The miniature cylinders 5 are symmetrically arranged at both ends of the movable crossbeam 42 and are connected to the solenoid valve 8 via air pipes 13, such as... Figure 1 and 3 As shown, the bottom of its cylinder is fixed to the movable crossbeam 42, and the piston rod 6 is connected to the fixed frame 41, thereby driving the pin group 43 to complete the marking action from bottom to top.

[0048] Furthermore, the laying mold 3 is made of acrylic sheet; the thickness of the acrylic sheet is 5 mm.

[0049] Its transparency allows operators to clearly observe whether the fabric is flat or shifted during placement, enabling timely adjustments and ensuring positioning accuracy.

[0050] Furthermore, the needle array 43 is made of rounded, blunt-tipped stainless steel and is paired with a transparent acrylic laying mold. This not only effectively prevents scratches on the fabric and operators, but also allows for real-time observation of the fabric laying status, ensuring the accuracy and safety of the placement process and improving the stability of the placement quality.

[0051] Furthermore, the suction table 2 is also equipped with a display 1, which is used to receive and display the current order parameters and corresponding seam stop information that are connected to the enterprise's production information system in real time. The display 1 simultaneously presents key data such as the number of seam stop points and garment length, which makes it easy for operators to quickly check and confirm before fixing the fabric, without having to manually check paper or electronic order information, effectively reducing the risk of operational errors.

[0052] In this embodiment, the operation of this device is as follows:

[0053] First, the system received a custom shirt order, requesting the setting of 7 hem points, and the shirt length must be within the standard customization range. The operator confirmed the number of points as 7 using monitor 1 at the workstation, and referred to the attached... Figure 2 The fabric is extended into the positioning groove 34 formed between the first positioning mold 31 and the second positioning mold, thereby avoiding areas where drilling is not required.

[0054] Next, lay the shirt fabric flat within the pre-reserved gap of the laying mold 3, ensuring the bottom edge of the collar is precisely aligned with the starting baseline. After positioning, the operator presses the foot switch of the pneumatic actuator; at this moment, the needle array moves rapidly upward under pneumatic drive, passing through the needle holes 10 on the positioning mold, simultaneously marking the 7 stop points in just 1 second. The first point is located 5 cm from the starting baseline, and the spacing between the remaining points is 9 cm.

[0055] Compared to the traditional manual location-based method, which takes approximately 51 seconds and has an error of 1-2 mm, this device can reduce the location-based time to less than 9 seconds while controlling the error to within ±0.3 mm, achieving an efficiency improvement of up to 82% and significantly enhancing quality stability. Furthermore, this automated process avoids employees repeatedly bending over and performing individual location-based operations, greatly reducing labor intensity.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
