[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-7 This utility model provides a technical solution: a precision zipper installation device for bag production, comprising:

[0028] The system includes an operating platform 1, a bag frame 2, an installation chain 3, a guide installation mechanism 4, and an abutment mechanism 5. The top of the operating platform 1 is equipped with an abutment mechanism 5 for limiting the bag frame 2, and the guide installation mechanism 4 is used to insert the installation chain 3 into the bag frame 2.

[0029] The guide installation mechanism 4 includes an installation frame 41 and a guide rail 42. The installation chain 3 is located between the two installation frames 41, and the two guide rails 42 are located inside the two installation frames 41 respectively.

[0030] Specifically, the design of the mounting frame 41 and the guide rail 42 ensures that the mounting chain 3 always moves along the preset path when inserted into the bag frame 2, avoiding skewing or misalignment during manual operation. This improves the straightness and consistency of the zipper 33 installation. The mounting chain 3 is located between the two mounting frames 41, thus preventing the mounting chain 3 from twisting or shifting during the conveying process. This ensures the precise alignment of the zipper 33 and the bag frame 2, making it convenient to fix the mounting chain 3 inside the bag frame 2 using a sewing machine. Through the coordinated work of the guide mounting mechanism 4 and the abutment mechanism 5, the mounting chain 3 can be easily fed into the bag frame 2.

[0031] The mounting chain 3 consists of mounting strips 31, guide parts 32 and zippers 33. The mounting chain 3 is located between two frames, the zipper 33 is located between two mounting strips, the two mounting strips 31 are located in the two mounting frames 41 respectively, and the guide parts 32 on the surface of the mounting strips 31 are set in the guide groove 42.

[0032] Furthermore, the bag frame 2 with the zipper 33 to be installed is placed on the operating table 1 and clamped and fixed by the abutment mechanism 5 to ensure its stable position. By inserting the two installation strips 31 of the installation chain 3 into the two installation strip frames 41 respectively, it can be ensured that its guide part 32 is embedded in the corresponding guide rail 42. The position of the installation chain 3 is adjusted so that the zipper 33 part is centered between the two installation strip frames 41. After the installation chain 3 is fully inserted into the bag frame 2, it can be finally fixed by sewing using equipment.

[0033] The fitting design of the guide part 32 and the guide rail 42 ensures that the installation chain 3 moves along the preset path and the installation straightness error is ≤0.3mm. The installation cloth strip 31 is wrapped by the installation frame 41, which can prevent the installation chain 3 from being deformed by uneven force during the pushing process. The flexible design of the installation cloth strip 31 can adapt to the curved bag frame 2, such as the rounded corner of the suitcase. The passive limiting structure of the guide part 32 and the guide rail 42 can solve the problem of skewing during the installation of the zipper 33.

[0034] The abutting mechanism 5 includes a frame 51, a driving component 50, a driving block 52, and a lower abutting plate 53. The top of the operating table 1 is provided with a frame 51 on both sides. The frame 51 is provided with a driving component 50 for moving the two driving blocks 52. The two lower abutting plates 53 are respectively connected to the two lower driving blocks 52.

[0035] Specifically, the bag frame 2 to be installed with zipper 33 is placed in the center of the operating table 1, so that the two frames 51 are located inside the bag frame 2. By starting the drive unit 50, the two drive blocks 52 are driven to move closer or further apart inside the frames 51, thereby adjusting the position of the lower abutment plate 53. The two lower abutment plates 53 move synchronously with the drive blocks 52 to abut and fix the inner wall of the bag frame 2, ensuring its stable position and preventing displacement during installation. This method is suitable for abutting and fixing bag frames 2 of different specifications.

[0036] The lower contact plate 53 is made of wear-resistant material, which provides sufficient friction during clamping to prevent the bag frame 2 from sliding. The drive component 50 can be linked with the PLC to achieve clamping or loosening. There is no complicated air circuit or hydraulic system, the failure rate is low, and the squeezing force of the contact plate will not be too large to avoid overpressure damage to the bag frame 2.

[0037] The drive unit 50 includes a dual-axis motor 501 and output rods 502. Both ends of the dual-axis motor 501 are equipped with output rods 502. The opposite ends of the two output rods 502 are rotatably mounted in the frame 51. The dual-axis motor 501 is mounted in the frame 51.

[0038] It is worth noting that, by sending a command through the control system, the dual-axis motor 501 is energized and starts operating. The output rods 502 at both ends of the motor begin to rotate synchronously. The rotation of the output rods 502 drives the linear movement of the drive block 52. Because the output rods 502 at both ends of the dual-axis motor 501 rotate synchronously, the movement speed and displacement of the drive blocks 52 on both sides are completely consistent, ensuring symmetry. Once the bag frame 2 is stably clamped, the dual-axis motor 501 stops operating and enters a locked state. The dual-axis motor 501 can then be manually activated via a control button. The lower contact plate 53 limits the box frame, which can shut down the dual-axis motor 501. The dual-axis motor 501 ensures that the output rods 502 on both sides are completely synchronized, avoiding the skew of the box frame 2 caused by single-sided drive. The clamping and positioning accuracy reaches ±0.2mm. The control of the dual-axis motor 501 by the control system is the existing technology. A dustproof plate is provided on the top of the dual-axis motor 501. The dustproof plate is located on the top of the two output rods 502, and the surface of the dustproof plate is slidably installed in the drive block 52. The dustproof plate is used to protect the output rods 502 and prevent dust accumulation.

[0039] A cylinder 6 for pushing the frame 51 is installed on the top of the control panel 1;

[0040] The system sends a signal to extend the piston rod of cylinder 6, which pushes frame 51 horizontally toward bag frame 2. After the zipper 33 is installed, the piston rod of cylinder 6 retracts, pulling frame 51 back to its initial position, making it easy to remove the finished product and place it into the next bag frame 2 to be processed. Cylinder 6 is a mature power component with a low failure rate and only requires periodic lubrication for maintenance, making it suitable for high-intensity factory environments. By adjusting the air pressure, the stopping position of frame 51 can be precisely controlled, with a repeatability accuracy of ±0.1mm. The output thrust is adjustable (0.1~0.8MPa), which can stably push heavy frame 51 without damaging thin materials. It adopts SMC standard cylinder 6 (model CDQ2B50-100D), with a magnetic switch to detect the stroke position and PLC linkage to control the pushing rhythm.

[0041] It also includes an adjusting component 7, which includes a threaded rod 71, an adjusting disc 72 and an upper contact disc 73. The top of the lower contact disc 53 is integrally machined with the threaded rod 71, and the inner circular hole of the upper contact disc 73 is located on the surface of the threaded rod 71. The surface of the threaded rod 71 is threaded with an adjusting disc 72 for adjusting the height of the upper contact disc 73.

[0042] Specifically, based on the height of the upper part of the bag frame 2, the distance between the upper abutment plate 73 and the lower abutment plate 53 is adjusted so that the installation chain 3 is located in the gap between the lower abutment plate 53 and the upper abutment plate 73. The purpose is to ensure that the lower abutment plate 53 and the upper abutment plate 73 do not affect the installation of the installation chain 3. The adjustment of the upper abutment plate 73 is achieved by rotating the adjustment plate 72 and moving it on the threaded rod 71, thereby adjusting the height of the upper abutment plate 73.

[0043] The height can be adjusted by manually rotating the adjustment disc 72 without tools. The surface of the adjustment disc 72 is also equipped with anti-slip texture to facilitate the operator to apply force. The self-locking characteristic of the threaded drive ensures that the pressure is stable and continuous without continuous energy consumption. It uses a stainless steel threaded rod 71 (M10×1.5 fine thread) in conjunction with the engineering plastic adjustment disc 72.

[0044] The bottom of the control panel 1 is provided with a rotating component 8, which includes a plate 81 and a driver 82. The bottom of the plate 81 is provided with the driver 82, and the output end of the driver 82 is installed at the bottom of the control panel 1.

[0045] Specifically, once one end of the zipper 33 is inserted and installed, the control system sends a command to start the driver 82, which drives the plate 81 to rotate via the output shaft. This rotates and adjusts the mounting frame, turning the side that is not installed to the operating surface for easy manual operation. Once the target angle is reached, the driver 82 is automatically stopped by manual control, ensuring that the operating table 1 is stable and does not shake.

[0046] The rotating control panel 1 allows for 360° rotation without blind spots, eliminating the tedious manual flipping of the bag frame 2. It is driven by a servo motor with an angle error of ≤0.5°. It uses a Delta ECMA series servo motor (200W) and a harmonic reducer to achieve high torque and precise rotation.

[0047] The top of the plate 81 is provided with a support ring 9, and four evenly distributed slide rails 10 are slidably installed on the top of the support ring 9. The tops of the four slide rails 10 are all installed on the top of the operating table 1.

[0048] When the driver 82 drives the plate 81 to rotate, the four slide rails 10 rotate synchronously with the plate 81. The slide rails 10 work in conjunction with the support ring 9 to provide low-friction support, ensuring smooth rotation without jamming. At the same time, the four slide rails 10 are evenly distributed to evenly transfer the weight of the operating table 1 and the bag frame 2 to the support ring 9. The slide rails 10 are made of chrome-plated steel or ceramic ball bearings, which are extremely wear-resistant and have a service life of over 500,000 rotations, requiring only one lubrication maintenance per year.

[0049] Furthermore, the wiring of its electrical components is sufficient to allow the control panel 1 to rotate more than one full turn. After the control panel 1 rotates one full clockwise turn, it needs to be rotated counterclockwise to return to its original position without the wiring affecting the rotation of the control panel 1.

[0050] The PLC system coordinates the timing of actions of each module: first, the cylinder 6 is triggered to push the frame 51 to the processing position; then the dual-axis motor 501 is started to contact the inner wall of the bag frame 2; finally, the rotating part 8 is called to adjust the angle as required.

[0051] Example: Installation of zipper 33 on a standard hard-shell suitcase;

[0052] Applicable products: 20-28 inch PC / ABS hard-shell suitcases;

[0053] Workflow: Place the suitcase frame on the operating table 1. Drive the dual-axis motor 501 to clamp the sides of the suitcase with the contact plate 53 (the pressure can be adjusted to 50N to avoid indentations); Zipper 33 installation: The guide rail 42 is selected with an 8mm wide groove, matched with the metal installation chain 3. The cylinder 6 pushes the installation frame 41 at a speed of 0.3m / s to complete the insertion of the long side zipper 33.

[0054] It is also suitable for soft travel backpacks with dual zipper 33 mounting and military tactical zipper 33 mounting.

[0055] This device: Place the bag frame 2 with the zipper 33 to be installed on the operating table 1 and clamp it with the abutment mechanism 5 to ensure its stable position. By inserting the two installation strips 31 of the installation chain 3 into the two installation strip frames 41 respectively, it can be ensured that its guide part 32 is embedded in the corresponding guide rail 42. Adjust the position of the installation chain 3 so that the zipper 33 part is centered between the two installation strip frames 41. After the installation chain 3 is fully inserted into the bag frame 2, the device can be used to finally fix it by sewing.

[0056] Place the bag frame 2 with the zipper 33 to be installed in the center of the operating table 1, so that the two frames 51 are located inside the bag frame 2. By starting the drive unit 50, the two drive blocks 52 are driven to move closer or further apart from each other inside the frames 51, thereby adjusting the position of the lower abutment plate 53. The two lower abutment plates 53 move synchronously with the drive blocks 52 to abut and fix the inner wall of the bag frame 2, ensuring its stable position and preventing displacement during installation. This method is suitable for abutting and fixing bag frames 2 of different specifications.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
