Description

Technical Field

[0001] This utility model relates to the field of textile and garment equipment technology, specifically to a waist elastic band positioning machine. Background Technology

[0002] In garment manufacturing, elastic waistbands are commonly used in areas such as trouser waistbands and skirt waistbands, requiring marking points on their surface to guide subsequent sewing or processing. Existing elastic waistband marking equipment often only allows for marking in a single direction (e.g., only up and down or only left and right), failing to simultaneously mark in multiple directions, resulting in low efficiency and inconsistent point placement. The movement of the moving table and the marking pen also lacks a synchronization mechanism, leading to point position deviations and affecting product consistency and quality. Traditional equipment has a relatively fixed structure, unable to be quickly adjusted to accommodate different specifications of elastic waistbands, exhibiting poor flexibility. Therefore, this invention designs an elastic waistband marking machine to solve the above problems.

[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a waist elastic band positioning machine.

[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is as follows: a waist elastic band positioning machine, comprising a horizontally set mounting platform that can be installed and docked with a work platform. A horizontal positioning platform is set on one side of the middle of the mounting platform. An upper positioning pen and a lower positioning pen that can move up and down are respectively set above and below the positioning platform. A right positioning pen that can move left and right is set on the right side of the positioning platform. A left moving platform and a right moving platform that can move left and right are respectively set on the left and right sides of the positioning platform. The right positioning pen is located on the right side of the right moving platform. The left moving platform, the right moving platform, and the positioning platform are all of the same thickness and their upper and lower end faces are flush. By setting up the upper positioning pen, the lower positioning pen, and the right positioning pen, multi-directional synchronous positioning operation can be achieved, significantly improving the positioning efficiency. The equal thickness and flush design of the left moving platform, the right moving platform, and the positioning platform ensures that the waist elastic band is placed stably, avoiding positioning deviations caused by uneven platforms, and improving positioning accuracy and product consistency.

[0006] Furthermore, the upper surface of the mounting platform is provided with a first guide rail and a second guide rail that are parallel to each other in the left-right direction; the left moving platform is drivenly connected to a first slider on the first guide rail; the right moving platform is drivenly connected to a second slider on the second guide rail; the right moving platform is provided with an integrated extension plate, which is drivenly connected to the right dot pen, realizing synchronous left-right movement of the right dot pen and the right moving platform. The extension plate is drivenly connected to a third slider on the first guide rail. This ensures the linear movement of the left moving platform, the right moving platform, and the right dot pen. The double guide rail structure ensures the linearity and stability of the moving platform movement; the extension plate is integrated with the right moving platform and connected to the right dot pen, realizing synchronous movement of the right dot pen and the right moving platform, ensuring the coordination between the right dot and the limit position of the moving platform; the third slider enhances the structural rigidity of the extension plate and further improves the movement accuracy.

[0007] Furthermore, a first rack that can move left and right is arranged parallel to the side of the first guide rail near the second guide rail, and a second rack that can move left and right is arranged parallel to the side of the second guide rail near the first guide rail; a rotatable gear is arranged between the first rack and the second rack, and the tooth surfaces of both the first rack and the second rack are meshed with the gear. Through the meshing transmission of the gear and the double rack, it is ensured that the first rack and the second rack can move precisely and synchronously in opposite directions, thereby driving the left and right moving stages to achieve strictly synchronous opposite or backward movements, effectively ensuring the symmetry of the point positions, and improving product quality and processing accuracy.

[0008] Furthermore, the left moving stage is connected to the first rack and pinion via a first connecting member; the right moving stage is connected to the second rack and pinion via a second connecting member; and the extension plate is connected to the first rack and pinion via a third connecting member. The left and right moving stages can move synchronously in opposite directions or in opposite directions, while the extension plate, carrying the right dot pen, moves synchronously with the right moving stage. The connecting members reliably transmit the linear motion of the rack to the moving stages and the extension plate, ensuring the synchronization of motion among the left and right moving stages and the right dot pen, simplifying the transmission structure, reducing cumulative motion errors, and improving the overall coordination and reliability of the equipment.

[0009] Furthermore, the second rack is fixedly connected to the fourth connecting member, which is movably mounted on the second guide rail via a fourth slider. The fourth slider is equipped with a lockable adjusting bolt. The adjusting bolt can lock or loosen the fourth slider to fix the second rack, thereby achieving the left and right moving stages in the left-right direction. The adjusting bolt allows for quick locking or loosening of the fourth slider, thus fixing the position of the second rack and enabling precise positioning and flexible adjustment of the left and right moving stages in the left-right direction. This adapts to the processing needs of elastic bands of different lengths, enhancing the versatility and ease of operation of the equipment.

[0010] Furthermore, a left limiting block and a right limiting block are detachably mounted on the left and right moving platforms, respectively. Each limiting block is connected to the left and right moving platforms via an oblong hole. The left and right limiting blocks limit the movement of the elastic band in the front-back direction. The limiting blocks, connected by the oblong holes, can be steplessly adjusted and fixed in the front-back direction, achieving precise positioning of elastic bands of different widths. This effectively prevents displacement during processing, improves the accuracy of repeated positioning, and the limiting blocks are detachable for easy maintenance and replacement.

[0011] Furthermore, a vertical upper mounting plate is provided on one side of the middle of the mounting platform, and the dot-matrix is ​​fixed on the upper mounting plate; the upper dot-matrix pen is detachably and vertically clamped on the upper clamp, which is located at the extended end of the first linear cylinder, and the first linear cylinder is fixed in the middle of the upper mounting plate; the lower dot-matrix pen is detachably and vertically clamped on the lower clamp, which is located at the extended end of the second linear cylinder, and the second linear cylinder is fixed in the middle of the lower mounting plate, which is fixed at the lower end of the mounting platform; the upper and lower dot-matrix pens are arranged vertically and vertically correspondingly. The use of linear cylinders to drive the upper and lower dot-matrix pens ensures fast, accurate, and uniform dot-matrix movement; the detachable installation of the upper and lower dot-matrix pens via clamps facilitates replacement and maintenance; the vertically and vertically corresponding design ensures the alignment of the dots on the upper and lower surfaces of the elastic band, improving the product's aesthetics and quality.

[0012] Furthermore, the right dot pen is detachably and horizontally mounted on the right clamp, which is located at the extended end of the third linear cylinder, which is fixed to the extension plate. The right dot pen is horizontally positioned and driven by the cylinder to achieve stable left-right dot positioning; its detachable installation via the right clamp facilitates refill replacement; and its fixation to the extension plate ensures synchronized movement with the right moving stage, matching the right dot position with the stage's limit position and guaranteeing overall dot coordination.

[0013] Furthermore, the dot-matrix pen is equipped with a connecting tube, which is an air tube. The air tube provides a constant air pressure to the pen refill, ensuring a continuous and stable supply of ink and avoiding problems such as blurry or intermittent dots caused by poor ink flow. This constant pressure ink supply method is particularly suitable for use scenarios with inverted pen refills, significantly improving the clarity and consistency of the dots.

[0014] Furthermore, the lower end of the mounting platform is equipped with two screw-on clamps distributed on the left and right. The clamp design allows the mounting platform to be quickly and securely fastened to work platforms of different sizes, simplifying the installation and disassembly process, improving the flexibility and efficiency of equipment deployment, and adapting to the needs of changing production environments.

[0015] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: 1. By setting up upper, lower, and right point pens, multi-directional synchronous point positioning can be achieved, improving point positioning efficiency and accuracy, and avoiding errors caused by multiple operations.

[0016] 2. The left moving platform, right moving platform, and point platform are all of the same thickness and their upper and lower ends are flush, which ensures that the waist elastic band is placed stably and the point positions are consistent, reducing deviations caused by uneven platforms.

[0017] 3. A rack and pinion synchronization mechanism is adopted to ensure that the left and right moving stages move synchronously in opposite directions or in opposite directions, thereby improving product symmetry and quality.

[0018] 4. The detachable limiting block connected by the waist-shaped hole facilitates adjustment of the limiting position, adapts to different sizes of waist elastic bands, and enhances the versatility of the equipment.

[0019] 5. The dot-mapping pen is connected via an air tube to ensure a constant pressure supply of ink, producing clear dots. It is especially suitable for inverted pen refills, solving the problem of uneven ink dispensing. Attached Figure Description

[0025] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0026] Example: This embodiment provides a waist elastic band positioning machine; see attached document. Figure 1 and attached Figure 2 As shown, the system includes a mounting platform 1, which is horizontally positioned and connected to a work platform via two screw-on clamps 19 at its lower end. A vertical upper mounting plate 11 is located on one side of the middle of the mounting platform 1, and a positioning platform 2 is fixed on the upper mounting plate 11. An upper positioning pen 3 and a lower positioning pen 4 are respectively positioned above and below the positioning platform 2, and both pens can move vertically. A right positioning pen 5 is located on the right side of the positioning platform 2, and it can move horizontally.

[0027] Left movable platform 6 and right movable platform 7 are respectively set on the left and right sides of the positioning platform 2, and right positioning pen 5 is located to the right of right movable platform 7. Left movable platform 6, right movable platform 7 and positioning platform 2 are of the same thickness and their upper and lower end faces are flush to ensure that the waist elastic band is placed stably and to avoid positioning deviation.

[0028] The upper surface of the mounting platform 1 is provided with a first guide rail 8 and a second guide rail 9 that are parallel to each other in the left-right direction. The left moving platform 6 is drivenly connected to the first slider 81 on the first guide rail 8, and the right moving platform 7 is drivenly connected to the second slider 91 on the second guide rail 9. The right moving platform 7 is provided with an integrated extension plate 10, which is drivenly connected to the right dot pen 5, so that the right dot pen 5 and the right moving platform 7 can move synchronously left and right. The extension plate 10 is also drivenly connected to the third slider 82 on the first guide rail 8 to enhance the stability of the movement.

[0029] See appendix Figure 3As shown, a first rack 12 is arranged parallel to the side of the first guide rail 8 near the second guide rail 9, and a second rack 13 is arranged parallel to the side of the second guide rail 9 near the first guide rail 8. A gear 14 is arranged between the first rack 12 and the second rack 13, and the gear 14 is rotatably mounted on the mounting platform 1 via a shaft. The tooth surfaces of both the first rack 12 and the second rack 13 mesh with the gear 14, so that the first rack 12 and the second rack 13 can move synchronously in opposite directions.

[0030] The left moving stage 6 is connected to the first rack 12 via the first connecting member 15, and the right moving stage 7 is connected to the second rack 13 via the second connecting member 16. The extension plate 10 is connected to the first rack 12 via the third connecting member 17. Thus, when the first rack 12 moves, it drives the second rack 13 to move in the opposite direction via the gear 14, causing the left moving stage 6 and the right moving stage 7 to move synchronously towards or away from each other. Simultaneously, the extension plate 10 drives the right point pen 5 to move synchronously with the right moving stage 7, ensuring point symmetry.

[0031] The second rack 13 is fixedly connected to the fourth connector 18, which is movably mounted on the second guide rail 9 via the fourth slider 92. An adjusting bolt 93 is provided on the fourth slider 92; tightening the adjusting bolt 93 locks the fourth slider 92, thereby fixing the position of the second rack 13 and achieving precise positioning of the left moving stage 6 and the right moving stage 7 in the left-right direction.

[0032] See appendix Figure 1 and attached Figure 2 As shown, a left limiting block 61 and a right limiting block 71 are detachably installed on the left moving platform 6 and the right moving platform 7, respectively. The left limiting block 61 and the right limiting block 71 are each connected to the left moving platform 6 and the right moving platform 7 through an oblong hole. By adjusting the position of the bolt in the oblong hole, the position of the left limiting block 61 and the right limiting block 71 in the front-back direction can be adjusted, thereby effectively limiting the elastic band and adapting to elastic bands of different sizes.

[0033] See appendix Figure 4 and attached Figure 5 As shown, the upper dot-matrix pen 3 is detachably and vertically mounted on the upper clamp 31, which is located at the extended end of the first linear cylinder 32, which is fixed to the middle of the upper mounting plate 11. The lower dot-matrix pen 4 is detachably and vertically mounted on the lower clamp 41, which is located at the extended end of the second linear cylinder 42, which is fixed to the middle of the lower mounting plate 43, which is fixed to the lower end of the mounting platform 1. The upper dot-matrix pen 3 and the lower dot-matrix pen 4 are arranged vertically and vertically, and their vertical movement is controlled by cylinders to ensure alignment of the upper and lower dots.

[0034] See appendix Figure 6As shown, the right dot pen 5 is detachably and horizontally mounted on the right clamp 51. The right clamp 51 is located at the extended end of the third linear cylinder 52. The third linear cylinder 52 is fixed on the extension plate 10. The cylinder controls the left and right movement to perform dot positioning, realizing multi-directional synchronous operation.

[0035] See appendix Figure 5 As shown, the lower dot pen 4 is equipped with a connecting tube 20, which is an air pipe connected to an external air source to ensure constant pressure of ink in the pen refill, uniform ink output, and clear dots, making it particularly suitable for inverted pen refills.

[0036] In a specific implementation, the mounting platform 1 is equipped with a mounting cover, see Appendix. Figure 1 As shown, it is used for protection and dust prevention.

[0037] Working process: Place the elastic band on the positioning platform 2, and rest it against the left limit block 61 and the right limit block 71. Adjust the positions of the left limit block 61 and the right limit block 71 according to the size of the elastic band, and fix the positions of the left moving platform 6 and the right moving platform 7 with the adjusting bolt 93. Start the equipment, and the upper positioning pen 3 and the lower positioning pen 4 move down and up simultaneously to mark the positions on the upper and lower surfaces of the elastic band. At the same time, the right positioning pen 5 moves to the left to mark the position on the right side of the elastic band. Through the synchronous movement mechanism, the positioning is accurate and efficient, greatly improving production efficiency and quality.

[0038] Working Principle: During operation, first loosen the adjusting bolt 93, place the elastic band onto the positioning platform 2, and rest it against the left limit block 61 and the right limit block 71. Adjust the position of the left limit block 61 and the right limit block 71 in the front-back direction according to the size of the elastic band (adjusted via the waist-shaped hole) to fit the width of the elastic band, and check the tightness by hand to ensure the elastic band is properly tensioned. Then tighten the adjusting bolt 93 to fix the position of the left moving platform 6 and the right moving platform 7 in the left-right direction, placing the elastic band seam to the left side of the left moving platform 6 (equivalent to a positioning point), completing the positioning of the elastic band. After adjustment, the operator presses the foot switch to start the equipment. The upper positioning pen 3 moves downward under the drive of the first linear cylinder 32, and the lower positioning pen 4 moves upward under the drive of the second linear cylinder 42, simultaneously marking positions on the upper and lower surfaces of the elastic band; the right positioning pen 5 moves to the left under the drive of the third linear cylinder 52, marking a position on the right side of the elastic band. Through the synchronization mechanism of the first rack 12, the second rack 13, and the gear 14, the left moving stage 6 and the right moving stage 7 move synchronously, ensuring the symmetry and accuracy of the point positions. After the points are positioned, each point pen returns to its initial position, and the elastic band can be removed.

[0039] Pen refill replacement method: 1. Replacement of the pen refills for the upper dot pen 3 and the right dot pen 5: First, remove the dot pen from the upper clamp 31 or the right clamp 51. Then, insert the new pen refill through the small hole at the top of the dot pen to push out the old pen refill. Next, fully insert the new pen refill into the housing of the dot pen. Finally, reinstall the dot pen onto the clamp.

[0040] 2. Replacement of the pen refill of the lower dot pen 4: First, remove the lower dot pen 4 from the slot of the lower clamp 41, remove the old pen refill from the air pipe connector of the connecting tube 20, then insert the tail of the new pen refill into the air pipe connector, and finally gently press the pen refill into the slot of the lower clamp 41 to fix it.

[0041] This utility model design for a rubber band dotting machine achieves multi-directional synchronous dotting by setting up upper, lower, and right dotting pens, significantly improving dotting efficiency and accuracy. The use of a uniformly thick and flush moving platform and dotting platform design ensures stable placement of the rubber bands, avoiding dotting deviations. A rack and pinion synchronization mechanism ensures synchronized movement of the left and right moving platforms, achieving symmetrical dotting. Adjustable limit blocks accommodate rubber bands of different sizes, enhancing the equipment's versatility. An air pipe connection ensures a constant pressure supply of ink, resulting in clear dots. Adjustable bolts achieve precise positioning, and clamps facilitate quick installation. The overall structure, combined with foot switch control and a simple pen refill replacement process, gives the equipment a comprehensive advantage of convenient operation, precise positioning, and strong adaptability.

[0042] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
