Description

Technical Field

[0001] This application relates to the technical field of belt loop coiling components, and in particular to a coiling device for preparing waist belt loops. Background Technology

[0002] In the garment manufacturing industry, the waistband loop of trousers, as a core structure that combines practicality and decoration, directly affects the overall quality and market competitiveness of the trousers due to its processing precision. Among the processing steps for the waistband loop, curling and shaping is one of the key processes. The core purpose of this process is to bend and shape the edge of the loop according to design requirements, making it conform to the waist curve and possess sufficient structural stability for subsequent sewing and fixing to the trouser body.

[0003] Currently, the industry generally uses a special bending mold to complete this operation. The operator passes the fabric of the waist belt loop to be processed along the outline of the bending mold. The mold guides and limits the belt loop to form a preset bending shape. Then, the shaped belt loop is transported to the sewing machine station and fixed by needle and thread sewing. The belt loop fabric is mostly made of textile fiber. During transportation, the fiber ends are prone to breakage or fuzzing, forming loose threads.

[0004] Regarding the aforementioned technologies, the inventors discovered that existing bending molds only have a single shaping function and do not integrate components for cutting and trimming the threads. This results in the threads not being removed in time during the processing, directly affecting the appearance of the waistband loops. Loose threads make the edges of the waistband loops appear rough and messy, reducing the visual quality of the product and affecting the durability and neatness of the pants. Utility Model Content

[0005] To overcome the limitations of existing bending molds that only have a single shaping function and lack integrated trimming components for the threads, resulting in the threads not being removed in time during the processing, directly affecting the appearance of the waistband loops, and causing the loose threads to make the edges of the waistband loops appear rough and messy, reducing the visual quality of the product and affecting the durability and neatness of the pants, this application provides a curling device for preparing waistband loops.

[0006] The present application provides a coiling device for preparing waistband loops, which adopts the following technical solution: A curling device for preparing waistband loops includes a curling mold body, scraping components, and support members. Two scraping components are symmetrically arranged in the vertical direction in the feed port of the curling mold body, and support members are assembled on both sides of the curling mold body. The scraping components include blades and scrapers. The blades are horizontally arranged in the feed port of the curling mold body, and scrapers are horizontally fixed on the horizontal end faces of adjacent blades in the two scraping components. The lower blades of the two scraping components are fixed to the bottom surface inside the feed port of the curling mold body, and the upper blades of the two scraping components can be lifted and installed on the upper side of the feed port of the curling mold body.

[0007] By adopting the above technical solution, and by setting up a scraping component, the scraping component uses blades and scrapers to scrape off the material entering the feed port of the coiling mold body, thus playing a cleaning role. When the material enters the feed port of the coiling mold body, the scraper can effectively scrape off excess glue or residue on the surface of the material, ensuring the cleanliness and flatness of the material surface, thereby ensuring the quality of the coiling formation. Setting up two scraping components, and setting scrapers on the horizontal end faces of the blades of adjacent scraping components, can improve scraping efficiency and thoroughness. The two scraping components in the vertical direction can scrape the material from both sides, ensuring that the material is completely scraped clean when it passes through the feed port. The double-layer scraping design makes the scraping more thorough, effectively avoiding the impact of residual glue or residue on the material surface on the coiling formation effect. The support component is set up to support and fix the coiling mold body and the scraping components, thereby ensuring the overall stability of the device and the reliability of the scraping component's operation. The specific principle is as follows: the support components are fixed on both sides of the curling mold body, acting as a stabilizing device and supporting the scraping assembly, allowing the blade and scraper to be securely installed and flexibly raised and lowered. This structural design ensures smooth movement of the scraping assembly during the raising and lowering process, thereby improving the scraping effect.

[0008] Optionally, two holes are symmetrically fixed on both sides of the horizontal end face of adjacent blades in the two scraping assemblies, and a pressure strip is horizontally provided on both sides of the horizontal end face of adjacent blades in the two scraping assemblies.

[0009] By adopting the above technical solution, and through the technical features of the perforated blocks and the pressure strips, the perforated blocks and the pressure strips form an effective gap adjustment mechanism, thus playing a role in precisely adjusting the distance between the spindles, thereby ensuring the tight contact and cutting accuracy between the scraper assembly and the spindle. Specifically, when adjacent blades in two scraping assemblies move closer or further apart, the perforated blocks and the pressure strips allow the blades to smoothly adjust their position to adapt to different workpiece sizes and cutting requirements.

[0010] Optionally, a pin is vertically fixed on the pressure bar, and the pin is slidably inserted into the hole block.

[0011] By adopting the above technical solution, and by setting a vertically fixed post on the pressure bar, and the post being slidably inserted into the hole, the post can slide along the hole and precisely fix the pressure bar at different positions, thus playing an adjustment and positioning role, thereby achieving precise adjustment and stable fixation of the pressure bar position.

[0012] Optionally, a compression spring is vertically fixed to the end of the insertion post, and the other end of the compression spring is fixed to the horizontal end face of the blade plate.

[0013] By adopting the above technical solution and incorporating the feature of a compression spring, the spring, due to its constant elasticity, can apply uniform pressure to the horizontal end face of the blade plate under the push of the insert post. This allows the insert post to stably push the blade plate along a predetermined path. Specifically, when the insert post moves downward, the compression of the compression spring provides precise thrust to the blade plate, ensuring that the blade plate can smoothly and powerfully cut into the material, achieving accurate and efficient cutting operations.

[0014] Optionally, a perforated strip is horizontally fixed at the upper part of the feed port of the curling die body.

[0015] By adopting the above technical solution, the perforated strip functions similarly to a guide device. It is fixed at the upper position of the feed port, and the upper scraping component can be installed through its horizontal layout.

[0016] Optionally, in the two scraping components, a guide rod is vertically fixed on the upper blade plate, and the guide rod is slidably inserted into the perforated strip. A compression spring is vertically sleeved on the outside of the guide rod, and the two ends of the compression spring are fixed to the perforated strip and the bottom end of the guide rod, respectively.

[0017] By adopting the above technical solution, and by setting a guide rod and a downward pressure spring on the upper blade plate, the guide rod is vertically fixed to the upper blade plate, while a vertical downward pressure spring is fitted around it, so that the two ends of the downward pressure spring are fixed to the perforated strip and the bottom end of the guide rod, respectively. The guide rod slides through the holes in the perforated strip, and this structural design facilitates the vertical movement and stable support of the scraping assembly. The combination of the guide rod and the perforated strip allows the scraping assembly to move freely up and down along the perforated strip. Specifically, when the scraping assembly moves downward, the downward pressure spring is compressed, providing elastic force for subsequent upward push. When the scraping assembly moves upward, the downward pressure spring returns to its original position, providing additional power to the scraping assembly.

[0018] Optionally, the support component includes a support slide frame, a locking rod is vertically slidably inserted through the top surface of the support slide frame, and a lifting spring is vertically fixed on the locking rod. The bottom end of the lifting spring is fixed to the top surface of the support slide frame, and the bottom surface of the support slide frame is fixedly assembled by fixing screws.

[0019] By adopting the above technical solution, the supporting slide frame, as the core component of the support, has a locking rod vertically slidably inserted into its top surface, and a lifting spring is fixed to the locking rod. The bottom end of the lifting spring is fixed to the top surface of the supporting slide frame. This structural design allows the locking rod to slide up and down relative to the supporting slide frame. Due to the presence of the lifting spring, the locking rod will automatically remain in a certain position when no external force is applied. When it is necessary to fix the locking rod, it can be pressed down by external force, at which point the lifting spring is compressed and stores a certain amount of energy. Conversely, when it is necessary to release the locking rod, simply lift the locking rod gently, and the lifting spring will release the previously stored energy, causing the locking rod to automatically return to its initial position, thus achieving the effect of locking and releasing.

[0020] Optionally, both sides of the outer wall of the curling mold body are horizontally fixed with assembly slides, and the assembly slides are vertically through-holes. The assembly slides are horizontally slidably inserted into the support slide frame, and the insertion holes on the assembly slides are limited by locking rods.

[0021] By adopting the above technical solution, and by setting up the assembly slide and insertion hole, the curling mold body can cooperate with the support slide frame, realizing a modular assembly method. This facilitates the combined use and quick replacement of different molds, effectively improving production efficiency and facilitating on-site adjustment and maintenance. When installation or disassembly is required, simply operate the locking rod to easily insert or remove the assembly slide from the support slide frame, enhancing the rapid assembly and disassembly of the curling mold body.

[0022] In summary, this application includes at least one of the following beneficial technical effects: A dual scraping assembly is installed at the feed port of the curling mold body. When the waistband loop fabric is fed in from the feed port, the pressure strips on both sides of the blade first compress and tighten the fabric, ensuring a smooth fabric surface and fully exposed threads. Subsequently, the upper and lower sides of the moving belt loop fabric are tightly pressed against the scraper of the blade, which can scrape away excess threads generated on the fabric surface in real time. This design of tightening before scraping avoids the problem of threads being hidden or incompletely scraped due to fabric laxity, significantly improving the thread removal rate, resulting in smooth and flat belt loop edges and significantly improved visual quality. Simultaneously, the timely removal of threads during processing effectively reduces the occurrence of threads falling off during subsequent wear, improving the overall durability and neatness of the pants and enhancing the product's market competitiveness.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a coiling device for preparing waistband loops. (See also...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A curling device for preparing waistband loops includes a curling mold body 1, scraping components 2, and support members 3. Two scraping components 2 are symmetrically arranged in the vertical direction in the feed port 11 of the curling mold body 1, and support members 3 are assembled on both sides of the curling mold body 1. The scraping components 2 include blades 21 and scrapers 22. The blades 21 are horizontally arranged in the feed port 11 of the curling mold body 1, and scrapers 22 are horizontally fixed on the horizontal end faces of adjacent blades 21 in the two scraping components 2. The lower blades 21 of the two scraping components 2 are fixed on the bottom surface inside the feed port 11 of the curling mold body 1, and the upper blades 21 of the two scraping components 2 can be lifted and installed on the upper side of the feed port 11 of the curling mold body 1.

[0027] By adopting the above technical solution, and by setting up a scraping component 2, the scraping component 2 uses a blade 21 and a scraper 22 to scrape the material entering the feed port 11 of the curling mold body 1, thereby playing a cleaning role. When the material enters the feed port 11 of the curling mold body 1, the scraper 22 can effectively scrape off excess glue or residue on the surface of the material, ensuring the cleanliness and flatness of the material surface, and thus ensuring the quality of the curling molding. Setting up two scraping components 2, and setting scrapers 22 on the horizontal end faces of the blades 21 of adjacent scraping components 2, can improve the scraping efficiency and thoroughness. The specific principle is that the two scraping components 2 in the vertical direction can scrape the material from both sides, ensuring that the material can be completely scraped clean when passing through the feed port 11. The double-layer scraping design makes the scraping more thorough and effectively avoids the influence of residual glue or residue on the material surface on the curling molding effect. Setting up a support component 3, the support component 3 supports and fixes the curling mold body 1 and the scraping component 2, thereby ensuring the overall stability of the device and the reliability of the scraping component 2. The specific principle is as follows: the support component 3 is fixed on both sides of the curling mold body 1, which acts as a stabilizing device and supports the scraping component 2, allowing the blade 21 and scraper 22 to be securely installed and flexibly raised and lowered. This structural design ensures the smooth movement of the scraping component 2 during the raising and lowering process, thereby improving the scraping effect.

[0028] Reference Figure 3In each of the two scraping assemblies 2, two holes 23 are symmetrically fixed on both sides of the horizontal end face of adjacent blades 21, and a retaining strip 24 is horizontally arranged on both sides of the horizontal end face of adjacent blades 21. Through the technical features of the holes 23 and retaining strips 24, an effective gap adjustment mechanism is formed, thus achieving precise distance adjustment between the spindles, ensuring tight contact and cutting accuracy between the scraper assembly 21 and the spindle. Specifically, when adjacent blades 21 in the two scraping assemblies 2 move closer or further apart, the holes 23 and retaining strips 24 allow the blades 21 to smoothly adjust their position to adapt to different workpiece sizes and cutting requirements. A vertically fixed post 25 is mounted on the retaining strip 24, and the post 25 is slidably inserted into the hole 23. By vertically fixing a post 25 to the pressure bar 24, and having the post 25 slide through and be inserted into the hole block 23, the post 25 can slide along the hole block 23, precisely fixing the pressure bar 24 at different positions. This provides adjustment and positioning, achieving precise adjustment and stable fixation of the pressure bar 24. A pressure spring 26 is vertically fixed to the end of the post 25, with the other end of the spring 26 fixed to the horizontal end face of the blade plate 21. This pressure spring 26, due to its constant elasticity, allows the horizontal end face of the blade plate 21 to experience uniform pressure under the push of the post 25, enabling the post 25 to stably push the blade plate 21 along a predetermined path. Specifically, when the post 25 moves downwards, the compression of the pressure spring 26 provides precise thrust to the blade plate 21, ensuring a smooth and powerful cut into the material, achieving precise and efficient cutting.

[0029] Reference Figure 3 and Figure 4A perforated strip 12 is horizontally fixed to the upper part of the feed port 11 of the curling die body 1. The perforated strip 12 functions as a guide device, fixed at the upper position of the feed port 11, and its horizontal layout allows the upper scraping assembly 2 to be installed. A guide rod 27 is vertically fixed to the upper blade plate 21 of the two scraping assemblies 2, and the guide rod 27 is slidably inserted through the perforated strip 12. A downward pressure spring 28 is vertically sleeved on the outside of the guide rod 27, and the two ends of the downward pressure spring 28 are respectively fixed to the perforated strip 12 and the bottom end of the guide rod 27. By setting the guide rod 27 on the upper blade plate 21 and the downward pressure spring 28, the guide rod 27 is vertically fixed to the upper blade plate 21, and the downward pressure spring 28 is sleeved on its outside, so that the two ends of the downward pressure spring 28 are respectively fixed to the perforated strip 12 and the bottom end of the guide rod 27. The guide rod 27 slides through a hole in the perforated strip 12, a design that facilitates the vertical movement and stable support of the scraping assembly 2. The combination of the guide rod 27 and the perforated strip 12 allows the scraping assembly 2 to move freely up and down along the strip. Specifically, when the scraping assembly 2 moves downwards, the compression spring 28 is compressed, providing elasticity for subsequent upward movement. When the scraping assembly 2 moves upwards, the compression spring 28 returns to its original position, providing additional power to the scraping assembly 2.

[0030] Reference Figure 4 and Figure 5The support component 3 includes a support slide frame 31. A locking rod 32 is vertically slidably inserted through the top surface of the support slide frame 31, and a lifting spring 33 is vertically fixed to the locking rod 32. The bottom end of the lifting spring 33 is fixed to the top surface of the support slide frame 31, and the bottom surface of the support slide frame 31 is fixedly assembled by fixing screws 34. The support slide frame 31, as the core component of the support component, has the locking rod 32 vertically slidably inserted on its top surface, and a lifting spring 33 is fixed to the locking rod 32. The bottom end of the lifting spring 33 is fixed to the top surface of the support slide frame 31. This structural design allows the locking rod 32 to slide up and down relative to the support slide frame 31. Due to the presence of the lifting spring 33, the locking rod 32 automatically remains in a certain position when no external force is applied. When it is necessary to fix the locking rod 32, it can be pressed down by external force, at which time the lifting spring 33 is compressed, storing a certain amount of energy. Conversely, when the locking rod 32 needs to be released, simply lift the locking rod 32 gently, and the lifting spring 33 will release the previously stored energy, causing the locking rod 32 to automatically return to its initial position, thus achieving the locking and releasing effect. The outer walls of the curling mold body 1 are horizontally fixed with assembly slides 13 on both sides, and each assembly slide 13 has a vertically penetrating insertion hole 131. The assembly slide 13 is horizontally slidably inserted into the support slide frame 31, and the insertion hole 131 on the assembly slide 13 is engaged with the locking rod 32 for limiting insertion. By setting the assembly slide 13 and the insertion hole 131, the curling mold body 1 can cooperate with the support slide frame 31, realizing a modular assembly method. This facilitates the combined use and quick replacement of different molds, effectively improving production efficiency and facilitating on-site adjustment and maintenance. When installation or disassembly is required, simply operate the locking rod 32 to easily insert or remove the assembly slide from the support slide frame, improving the quick assembly and disassembly of the curling mold body 1.

[0031] The implementation principle of a coiling device for preparing waist belt loops in this application embodiment is as follows: First, when installing the curling mold body 1, the bottom end of the support slide frame 31 in the support component 3 is fixed to the installation body by fixing screws 34. Then, the locking rod 32 is pulled vertically upward on the bottom surface of the support slide frame 31, which causes the lifting spring 33 to deform. Then, the assembly slides 13 on both sides of the curling mold body 1 are horizontally slid and assembled in the support slide frame 31. Then, the locking rod 32 is released and, under the action of the deformation force of the lifting spring 33, the locking rod 32 is pushed to penetrate and insert into the insertion hole 131 of the assembly slide frame 13, thus locking the installation of the support component 3 and the curling mold body 1. Then, when preparing the waist belt loop by curling, the waist belt loop fabric is fed into the feed port 11 of the curling mold body 1 and pulled out from the curling discharge port of the curling mold body 1. The pulled waist belt loop fabric passes through the two scraping components 2 between the feed ports 11 of the mold body 1. The waist belt loop fabric is squeezed and tightened by the pressure strips 24 on both sides of the blades 21 of the two scraping components 2. The adjacent scrapers 22 of the blades 21 on the upper and lower sides of the moving waist belt loop fabric press against the upper and lower sides of the waist belt loop fabric to scrape off the excess threads generated on the waist belt loop fabric, thus completing the scraping of the threads on the surface of the waist belt loop.

[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
