Abstract
Description
Technical Field
[0001] This utility model relates to the field of bag manufacturing equipment technology, and in particular to a lining binding machine. Background Technology
[0002] In the luggage manufacturing industry, the lining, or inner layer of fabric, is an important component of the product. Its edges usually need to be bound. The main functions of the binding process include improving the neatness of the product's appearance, enhancing the edge's resistance to wear and tear, preventing loose threads or fibers, thereby extending the product's service life and improving the user experience.
[0003] Traditional lining binding primarily relies on manual operation or semi-automated equipment. The core process involves aligning the binding tape with the lining edge and then sewing them together. However, in the tape feeding stage, traditional equipment typically uses a simple horizontal unwinding structure with a roller. During unwinding, the tape is prone to loosening, shifting, or even wrinkling due to its own curling stress or uneven tension, making it difficult to guarantee positional accuracy during subsequent feeding. Furthermore, the tape output from the roller is usually vertical, meaning its length is perpendicular to the horizontal plane. Sewing machine heads typically require the tape to be horizontal, parallel to the lining edge, for precise sewing. Therefore, a guiding mechanism is needed to convert the vertical tape to a horizontal position. However, current technology lacks optimized designs specifically for this conversion process, often leading to tape deviation, folding, or sudden tension changes during the posture change, thus affecting the accuracy of the sewing position.

[0035] In the luggage manufacturing industry, the lining, or inner layer of fabric, is an important component of the product. Its edges usually need to be bound. The main functions of the binding process include improving the neatness of the product's appearance, enhancing the edge's resistance to wear and tear, preventing loose threads or fibers, thereby extending the product's service life and improving the user experience.
[0036] Traditional lining binding primarily relies on manual operation or semi-automated equipment. The core process involves aligning the binding tape with the lining edge and then sewing them together. However, in the tape feeding stage, traditional equipment typically uses a simple horizontal unwinding structure with a roller. During unwinding, the tape is prone to loosening, shifting, or even wrinkling due to its own curling stress or uneven tension, making it difficult to guarantee positional accuracy during subsequent feeding. Furthermore, the tape output from the roller is usually vertical, meaning its length is perpendicular to the horizontal plane. Sewing machine heads typically require the tape to be horizontal, parallel to the lining edge, for precise sewing. Therefore, a guiding mechanism is needed to convert the vertical tape to a horizontal position. However, current technology lacks optimized designs specifically for this conversion process, often leading to tape deviation, folding, or sudden tension changes during the posture change, thus affecting the accuracy of the sewing position.
[0037] Therefore, such as Figures 1 to 5As shown, the lining binding machine proposed in this utility model includes a base 100, a worktable 110 disposed on the base 100, a winding wheel 130 disposed on the worktable 110, and a guide assembly 200 disposed on the worktable 110 and located at the output end of the winding wheel 130. The center line of the winding wheel 130 is arranged vertically and used for horizontal unwinding of the winding belt 131. The guide assembly 200 includes a vertical guide plate 210 and a horizontal guide block 220. Specifically, the sidewall of the vertical guide plate 210 abuts against the surface of the tape 131, and the horizontal guide block 220 is located on the output side of the vertical guide plate 210. Further, the horizontal guide block 220 is provided with a horizontally extending and through guide groove 2201 for the tape 131 to pass through and switch the tape 131 to a horizontal state. Additionally, the base 100 is provided with a sewing machine head 120, located at the output end of the guide groove 2201, to sew the tape 131 onto the outer periphery of the lining. In some applications, the user holds the lining, aligning the edge of the lining with the tape 131 output from the horizontal guide block 220, and then starts the sewing machine head 120 to sew the lining and tape 131 together. Then, the user moves the lining, causing the tape 131 to move together, and with the continuous operation of the sewing machine head 120, the entire periphery of the lining is sewn together. Understandably, the sewing machine head 120 can be referenced from common sewing machines and can be operated by foot pedal; the specific structure will not be detailed here. It should be noted that the sewing machine head 120 is integrated into the base 100, and the worktable 110 is equipped with a vertical winding wheel 130 to achieve horizontal unwinding of the tape 131. The guide assembly 200 guides the vertically output tape 131 through the vertical guide plate 210 and smoothly converts it to a horizontal state via the horizontal guide groove 2201 of the horizontal guide block 220. This ensures that the tape 131 is accurately delivered to the area below the sewing machine head 120 for sewing. The structural design is reasonable and solves the problems of difficult tape 131 guidance, unstable delivery, and low positional accuracy in traditional hemming processes. It effectively improves hemming efficiency and quality, reduces manual intervention, and adapts to the needs of continuous production.
[0038] In some embodiments of this utility model, reference is made to Figure 2The guide groove 2201 has a vertical width of A and a thickness of B for the tape 131, satisfying A≥B. This ensures that the guide groove 2201 has sufficient space to prevent the tape 131 from being squeezed or damaged by friction when passing through the groove. This avoids stitching defects caused by compression deformation of the tape 131's edges and ensures the free passage of the tape 131 in the vertical direction, providing a foundation for subsequent stable conveying and precise stitching. At the same time, the structure is simple and easy to implement, effectively improving the equipment's compatibility with standard thickness tapes 131. Optionally, B≤A≤B+2mm, while satisfying the basic accommodating function of the guide groove 2201, the width margin is strictly controlled within 2mm. This prevents the tape 131 from swaying or shifting laterally during conveying due to the excessive width of the guide groove 2201, and also avoids the problem of the tape 131 being squeezed due to the excessive width of the guide groove 2201. Through precise dimensional matching, the posture stability and positional control of the tape 131 during conveying are achieved, which significantly improves the alignment accuracy of the tape 131 and the inner sleeve during sewing, thereby ensuring the neatness of the edge stitching and the product appearance quality.
[0039] Refer to Figure 2In some embodiments of this utility model, an opening 22011 is provided at one end of the guide groove 2201 in the transverse and perpendicular extension direction of the guide groove 2201, so that the tape 131 can partially extend out of the transverse guide block 220 in the transverse direction. This provides adjustment space for the pre-alignment operation of the tape 131 and the inner sleeve. The operator or the automated mechanism can quickly correct the relative position of the tape 131 and the edge of the inner sleeve by adjusting the position of the extended portion of the tape 131, avoiding the sewing offset caused by the initial alignment deviation. At the same time, the structure of the opening 22011 does not affect the main guiding function of the guide groove 2201 body for the tape 131, taking into account the balance between conveying stability and operational flexibility, and improving the adaptability and debugging efficiency of the edge binding process. Furthermore, in some embodiments of this utility model, the transverse guide block 220 is provided with a transversely extending and through-hole release groove 22012. In the transverse direction perpendicular to the extension of the guide groove 2201, the release groove 22012 is located at the other end of the guide groove 2201, and the inner diameter of the release groove 22012 is larger than the thickness of the guide groove 2201. In this way, the release groove 22012 provides additional buffer space for the roll 131. When the roll 131 undergoes slight deformation due to fluctuations in unwinding tension or changes in conveying resistance, the release groove 22012 can accommodate the deformed portion through its larger inner diameter, preventing stress concentration that could lead to breakage or wrinkling of the roll 131. Simultaneously, it works in conjunction with the guide groove 2201 to form a "constraint-buffering" segmented conveying structure, ensuring accurate positioning of the main conveying path of the roll 131 while releasing local tension through the release groove 22012, thus improving the stability and reliability of the roll 131 conveying process. Optionally, the release trough 22012 is cylindrical. The regular geometry ensures that the contact surface of the tape 131 within the release trough 22012 is uniformly stressed, avoiding localized friction or jamming caused by irregularly shaped trough walls. Furthermore, the cylindrical structure further simplifies the processing technology and reduces manufacturing costs. At the same time, it complements the rectangular or near-rectangular cross-section of the guide trough 2201, satisfying the mechanical requirements of the tape 131 in different sections, such as precise constraint in the guide section and flexible release in the release section, while maintaining the simplicity and functionality of the overall structure. This effectively improves the smoothness of tape 131 conveying and its long-term durability.
[0040] In some embodiments of this utility model, the guide assembly 200 is provided with a damping structure to dampen the conveying of the tape 131. This solves the problem in traditional equipment where the tape 131 is prone to slippage due to insufficient unwinding tension or deformation and breakage due to excessive tension. The damping structure adjusts the friction between the tape 131 and the guide assembly 200, ensuring that the tape 131 maintains a stable conveying tension. This ensures that the tape 131 feeds smoothly and at a uniform speed throughout its path from the roller 130 to the sewing machine head 120, avoiding quality problems such as uneven stitches and tape 131 deviation caused by speed fluctuations or sudden tension changes. This significantly improves the consistency and reliability of the edging process. Specifically, refer to... Figure 3 and Figure 4 In some embodiments of this utility model, the damping structure includes a pressing member 300, which is snapped onto the vertical guide plate 210. The pressing member 300 and the vertical guide plate 210 allow the winding belt 131 to pass through, and the pressing member 300 presses against the surface of the winding belt 131. It is understood that applying damping force by directly pressing the surface of the winding belt 131 with the pressing member 300 results in a simple structural design and convenient installation. The snap-fit fixing method allows for adjustment or replacement without additional tools. The fit gap between the pressing member 300 and the vertical guide plate 210 can be flexibly adjusted according to the thickness of the winding belt 131, ensuring that the damping force is evenly applied to the surface of the winding belt 131. This prevents unstable conveying caused by the slippage of the winding belt 131 and avoids excessive compression damage to the winding belt 131, achieving a balance between the precision of damping adjustment and ease of operation. Specifically, the crimping component 300 is an elastic part that is fixed to the vertical guide plate 210 via an elastic snap-fit. The elastic material properties allow the crimping component 300 to adapt to minor undulations or unevenness on the surface of the tape 131, compensating for gap differences through elastic deformation to ensure uniform distribution of damping force. Simultaneously, the elastic snap-fit structure further simplifies the installation and disassembly process, allowing for quick fixing and position adjustment of the crimping component 300 without bolts or other fasteners. When the thickness of the tape 131 changes, only the crimping component 300 with a different elastic coefficient needs to be replaced to match the new damping requirements, significantly improving the equipment's adaptability to diverse tape 131 specifications and maintenance efficiency. It should be noted that the crimping component 300 can be based on a structure similar to a paperclip. Furthermore, the crimping member 300 is a looping elastic element. In its normal state, the crimping member 300 is a flat element. After being inserted into the vertical guide plate 210, the multiple rings of the crimping member 300 can deform and have a restoring force towards the center. At this time, the multiple rings alternately press against the opposite surfaces of the vertical guide plate 210, thus achieving convenient installation of the crimping member 300 and providing a certain resistance force on the belt 131, reducing the resistance during conveying. (See reference...) Figure 4After the vertical guide plate 210 is inserted, the crimping member 300 includes a plurality of first crimping parts 310, a plurality of second crimping parts 320 and a plurality of connecting parts 330. The first crimping parts 310 and the second crimping parts 320 are respectively disposed on both sides of the vertical guide plate 210. The plurality of first crimping parts 310 are arranged at intervals along the conveying direction of the belt 131 and press the belt 131 against the vertical guide plate 210. The plurality of second crimping parts 320 are arranged at intervals along the conveying direction of the belt 131 and press against the vertical guide plate 210. The plurality of connecting parts 330 are respectively connected to the first crimping parts 310 and the second crimping parts 320. To address this, a multi-point distributed pressing method was used to achieve localized uniform damping control of the belt 131, avoiding local deformation caused by excessive pressure at a single point or slippage caused by insufficient pressure at a single point. Furthermore, the spaced first pressing part 310 further reduced the contact area between the belt 131 and the pressing part 300, reducing friction loss and making the pressure on the belt 131 more balanced.
