Description

Technical Field

[0001] This utility model belongs to the technical field of trolley case production equipment, specifically relating to a complete set of trolley case zipper sewing equipment. Background Technology

[0002] A rolling suitcase is an item used to carry clothing when traveling. A typical rolling suitcase on the market consists of an upper and lower section, connected by a zipper along three of its longer sides. Due to this structure, the zipper needs to be sewn onto the upper and lower sections during production, forming the rolling suitcase zipper sewing process.

[0003] In the prior art, for example, Chinese utility model patent with publication number CN222139481U and publication date December 10, 2024 discloses a zipper sewing device for producing trolley cases, including a fixed frame, a sewing module on the fixed frame, the sewing module including a table and a sewing machine body, a mounting frame slidably mounted on the fixed frame, a first drive mechanism on the fixed frame to drive the mounting frame to move, an operating table rotatably connected to the mounting frame, the center line of the operating table and the center line of the upper surface of the table being on the same straight line, a first linear module fixedly connected to the operating table, a second linear module fixedly connected to the moving end of the first linear module, a clamp for fixing the case body on the moving end of the second linear module, and a second drive mechanism on the mounting frame to drive the operating table to rotate.

[0004] In the structure of this zipper sewing device for trolley case production, the first linear module and the second linear module are linear reciprocating motion mechanisms. The first linear module and the second linear module, which are used to adjust the position of the trolley case, are set on a rotating operating table. Therefore, during the operation of the zipper sewing device for trolley case production, the control line of the linear reciprocating motion mechanism will become entangled, especially at the joint position, where fatigue fracture is likely to occur.

[0005] On the other hand, since the linear reciprocating motion mechanism used to adjust the position of the suitcase is biased on the operating table, interference problems will occur, making it impossible to rotate the suitcase to the upper position, and therefore it is impossible to zipper sew on more than three sides.

[0006] On the other hand, suitcases are usually made of a relatively soft material like ABS, so they are prone to deformation during operation due to being pulled, which can cause the stitching to be misaligned.

[0007] Another issue is that the zipper is prone to falling off once the seam is cut. Utility Model Content

[0008] The purpose of this invention is to provide a complete set of sewing equipment for zippers on suitcases, which can prevent misaligned sewing.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A complete set of equipment for sewing zippers on a suitcase includes a frame, a sewing device mounted on the frame, an auxiliary sewing mechanism on the sewing side of the sewing device, and a stop plate installed at a position corresponding to the sewing end of the sewing device, extending upward from below the sewing device.

[0010] Based on the above scheme and as a preferred embodiment of the above scheme, the abutment plate is provided with rotatable rollers.

[0011] Based on the above scheme and as a preferred embodiment of the above scheme, the upper end of the abutment plate is provided with a notch for accommodating the sewing end of the sewing device.

[0012] Based on the above scheme and as a preferred embodiment, the auxiliary sewing mechanism includes a movable seat. The output end of the movable seat can reciprocate along the sewing direction, and the output end of the movable seat is controlled by a coordinate linear reciprocating motion mechanism to reciprocate along the sewing direction. The output end of the movable seat is provided with a first mounting frame. The first mounting frame is provided with a first coordinate linear reciprocating motion mechanism arranged along the height direction. The output end of the first coordinate linear reciprocating motion mechanism is provided with a second mounting frame that can be driven by it. The second mounting frame is provided with a rotatable mounting plate. The drive mechanism mounted on the second mounting frame is connected to the mounting plate and drives the mounting plate to rotate. The mounting plate is provided with a pull-luggage mounting mechanism. A zipper guide mechanism is provided in front of the sewing device.

[0013] Based on the above scheme and as a preferred embodiment of the above scheme, the trolley case mounting mechanism positions the center of the trolley case relative to the rotation center of the mounting plate, and the trolley case mounting mechanism can approach and move away from the sewing end of the sewing device in the axial direction of the mounting plate.

[0014] Based on the above scheme and as a preferred embodiment of the above scheme, the trolley case mounting mechanism includes a suction cup, which is fixed to the mounting plate. The suction cup is connected to a vacuum pump via a solenoid valve, and the controller controls the operation of the solenoid valve.

[0015] Based on the above scheme and as a preferred embodiment of the above scheme, the trolley case mounting mechanism further includes a limiting plate, which is connected to the mounting plate. The inner side of the limiting plate limits the trolley case accommodating space, and the center of the trolley case accommodating space is opposite to the return center of the mounting plate.

[0016] Based on the above scheme and as a preferred embodiment, the movable seat is a cross-shaped movable seat, which includes a second coordinate linear reciprocating motion mechanism, a third coordinate linear reciprocating motion mechanism, a first assembly table, and a second assembly table. The output end of the second coordinate linear reciprocating motion mechanism is connected to the first assembly table, and the third coordinate linear reciprocating motion mechanism is installed on the first assembly table. The output end of the third coordinate linear reciprocating motion mechanism is connected to the second assembly table. One of the second coordinate linear reciprocating motion mechanism and the third coordinate linear reciprocating motion mechanism is arranged along the sewing direction. The controller controls the operation of the second coordinate linear reciprocating motion mechanism and the third coordinate linear reciprocating motion mechanism.

[0017] Based on the above scheme and as a preferred embodiment, the guiding mechanism includes a guide with a material trough and a connecting platform. A clamping block is positioned corresponding to the connecting platform. A clamping drive mechanism controls the clamping block to move away from or near the connecting platform. A controller controls the clamping drive mechanism to operate. The guide is connected to the output end of a fourth linear reciprocating motion mechanism. The fourth linear reciprocating motion mechanism enables the guide to have positions close to and far from the sewing end of the sewing device. The controller controls the fourth linear reciprocating motion mechanism to operate.

[0018] Based on the above solution and as a preferred embodiment, the invention further includes a first cutting mechanism for cutting the zipper, located at the front of the sewing device and mounted on the output end of the fifth linear reciprocating motion mechanism; it also includes a second cutting mechanism for cutting the thread, mounted on the side of the sewing device via a sixth linear reciprocating motion mechanism. The significant and beneficial technical effects of this invention compared to the prior art are: This utility model relates to a complete set of sewing equipment for zippers on suitcases. It adopts a support plate structure. During the sewing process, since the support plate is set on the support plate, the suitcase can be sewn with the support plate as a reference position. This ensures that the zipper on the suitcase is always sewn in the predetermined position, resulting in straighter seams and effectively preventing sewing deviation. Attached Figure Description

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

[0031] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated; in describing a feature containing "second," there is no implication that a suitcase zipper sewing kit already contains a feature containing "first."

[0033] This utility model discloses a complete set of equipment for sewing zippers on suitcases, which is used to sew suitcases 100a and zippers together. It should be noted that suitcase 100a is the object of operation of the complete set of equipment. In the description of this embodiment, suitcase 100a refers to a semi-finished product such as the upper or lower box body.

[0034] The zipper sewing equipment for suitcases includes a frame 1, on which a sewing device 2 is mounted. It should be noted that the sewing device 2 has a sewing end 3, at which it sews the zipper to the suitcase. The sewing device 2 is existing technology and is conventionally used in this field; therefore, its structure will not be described in detail here. An auxiliary sewing mechanism 5 is provided on the sewing side 4 of the sewing device 2.

[0035] In this invention, the auxiliary sewing mechanism 5 includes a movable seat 6 that can be reciprocated along the sewing direction, and a first mounting bracket 7 is provided on the movable seat 6. In this embodiment, as shown in the figure, the height of the movable seat 6 is lower than the height of the sewing end 3 of the sewing device 2. When the movable seat 6 reciprocates along the sewing direction, the first mounting bracket 7 moves synchronously with the movable seat 6.

[0036] A first coordinate-type linear reciprocating motion mechanism 8, arranged along the height direction, is mounted on the first mounting frame 7. A second mounting frame 9, which can be driven by the first coordinate-type linear reciprocating motion mechanism 8, is mounted on the first mounting frame 7. In this embodiment, the first coordinate-type linear reciprocating motion mechanism 8 adopts a linear module structure. Typically, a linear module includes a lead screw pair, a guide rail pair, and a drive device, etc., with the drive device being connected to the lead screw pair in a transmission connection. In this embodiment, the lead screw pair and the guide rail pair are mounted on the first mounting frame 7 along the height direction. The nut in the lead screw pair and the slider in the guide rail pair are both connected to the second mounting frame 9. Thus, the first coordinate-type linear reciprocating motion mechanism 8 controls the movement of the second mounting frame 9 in the height direction. In this invention, a controller controls the operation of the first coordinate-type linear reciprocating motion mechanism 8.

[0037] A rotatable mounting plate 10 is provided on the second mounting frame 9. A drive mechanism 11 mounted on the second mounting frame 9 is connected to the mounting plate 10 and drives the mounting plate 10 to rotate. In this embodiment, the mounting plate 10 is mounted on the second mounting frame 9 via a rotary drive device (also referred to as a slewing bearing in some documents). The drive mechanism 11 is connected to the input end of the rotary drive device, thereby controlling the rotation of the mounting plate 10. Typically, the drive mechanism 11 uses a servo motor or a stepper motor, but other types of motors can also be used. The controller controls the operation of the drive mechanism 11. When the sewing device 2 is used to sew the zipper to the arc angle 10a of the trolley case, the controller controls the drive mechanism 11, thereby causing the mounting plate 10 to rotate. This, in conjunction with the movement of the moving seat 6 and the operation of the first coordinate linear reciprocating motion mechanism 8, forms a three-axis linkage.

[0038] A suitcase mounting mechanism 12 is provided on the mounting plate 10. In practical applications, the suitcase mounting mechanism 12 is used to fix the suitcase, allowing the suitcase to rotate with the mounting plate 10. In this embodiment, the suitcase mounting mechanism 12 includes a suction cup 13 and a vacuum pump, etc. When the suitcase is against the suction cup 13, the vacuum pump creates a negative pressure on the suction cup 13, thereby fixing the suitcase to the suction cup 13. In this utility model, the suitcase mounting mechanism 12 enables the center of the suitcase to be located relative to the rotation center of the mounting plate 10.

[0039] A zipper guide mechanism 14 is provided at the front of the sewing device 2. The zipper guide mechanism 14 is used to guide the zipper to the sewing end 3 of the sewing device 2.

[0040] In operation, the operator assembles the suitcase into the suitcase mounting mechanism 12, securing it in place. The moving seat 6 moves, and the suitcase enters the sewing end 3 of the sewing device 2. At this point, the suitcase is in the sewing position, and the zipper is pulled to the sewing end 3 of the sewing device 2. The sewing device 2 then sews the zipper and suitcase together. Typically, the zipper is sewn onto the suitcase starting from the straight edge (the longer edge). After the sewing device 2 begins operation, the moving seat 6 moves backward (away from the direction of the zipper guide mechanism). The moving speed of the moving seat 6 is the same as that of the sewing device 2. The sewing speed is matched until the zipper is continuously sewn to the end of the longer edge of the suitcase. When sewing the arc angle where the long side of the suitcase transitions to the short side, the controller controls the mounting plate to rotate and simultaneously controls the moving seat to move forward. Correspondingly, the suitcase mounting mechanism 12 moves the suitcase forward (in the opposite direction of the moving seat when sewing the straight edge). During the forward movement of the moving seat, the controller first controls the first coordinate type linear reciprocating motion mechanism 8 to move the second mounting frame 9 downward and then controls the first coordinate type linear reciprocating motion mechanism 8 to move the second mounting frame 9 upward, adapting to the change in the distance between the center of the suitcase and the sewing end of the sewing device. Typically, when the second mounting bracket 9 reaches the center of the trolley case mounting mechanism 12 and is directly below the sewing end 3 of the sewing device 2, it moves upward. After the mounting plate 10 rotates 90 degrees, the second mounting bracket 9 moves to a height that aligns the center of the trolley case with the height of the sewing end 3 of the sewing device 2. At this point, the shorter edge of the trolley case is at the sewing end 3 of the sewing device 2. The sewing device 2 continues to sew the zipper to the shorter edge of the trolley case, while the moving seat 6 moves backward until the zipper is continuously sewn to the shorter edge of the trolley case. At the end of the edge; when sewing the arc angle where the short side of the suitcase transitions to the long side, the controller controls the mounting plate to rotate and simultaneously controls the moving seat to move forward. Correspondingly, the suitcase mounting mechanism 12 moves the suitcase forward. During the forward movement of the moving seat, the controller first controls the first coordinate type linear reciprocating motion mechanism 8 to move the second mounting frame 9 downward, and then controls the first coordinate type linear reciprocating motion mechanism 8 to move the second mounting frame 9 upward, adapting to the change in the distance between the center of the suitcase and the sewing end of the sewing device.Typically, when the second mounting bracket 9 reaches the center of the suitcase mounting mechanism 12 and is directly below the sewing end 3 of the sewing device 2, it moves upward. After the mounting plate 10 rotates 90 degrees, the second mounting bracket 9 moves to a height that aligns the center of the suitcase with the height of the sewing end 3 of the sewing device 2. At this point, the longer edge of the suitcase is at the sewing end 3 of the sewing device 2. The sewing device 2 continues to sew the zipper to the longer edge of the suitcase, while the moving seat 6 moves backward until the zipper is continuously sewn to the end of the longer edge of the suitcase. When sewing the arc angle where the long side transitions to the short side, the controller controls the mounting plate to rotate and simultaneously controls the moving seat to move forward. Correspondingly, the trolley case mounting mechanism 12 moves the trolley case forward (in the opposite direction of the moving seat's movement when sewing the straight side). During the forward movement of the moving seat, the controller first controls the first coordinate type linear reciprocating motion mechanism 8 to move the second mounting frame 9 downward, and then controls the first coordinate type linear reciprocating motion mechanism 8 to move the second mounting frame 9 upward, adapting to the change in the distance between the center of the trolley case and the sewing end of the sewing device. Typically, when the second mounting bracket 9 reaches the center of the trolley case mounting mechanism 12 and is directly below the sewing end 3 of the sewing device 2, it moves upward. After the mounting plate 10 rotates 90 degrees, the second mounting bracket 9 moves to a height that aligns the center of the trolley case with the height of the sewing end 3 of the sewing device 2. At this point, the shorter edge of the trolley case is at the sewing end 3 of the sewing device 2. The sewing device 2 continues to sew the zipper to the shorter edge of the trolley case, while the moving seat 6 moves backward until the zipper is continuously sewn to the end of the shorter edge of the trolley case. When sewing the arc angle transitioning from the short side to the long side, the controller controls the mounting plate to rotate and simultaneously controls the moving seat to move forward. Correspondingly, the trolley case mounting mechanism 12 moves the trolley case forward (in the opposite direction of the moving seat's movement when sewing the straight side). During the forward movement of the moving seat, the controller first controls the first coordinate type linear reciprocating motion mechanism 8 to move the second mounting frame 9 downward, and then controls the first coordinate type linear reciprocating motion mechanism 8 to move the second mounting frame 9 upward, adapting to the change in the distance between the center of the trolley case and the sewing end of the sewing device. Typically, when the second mounting bracket 9 moves from the center of the suitcase mounting mechanism 12 to directly below the sewing end 3 of the sewing device 2, it moves upward. After the mounting plate 10 rotates 90 degrees, the second mounting bracket 9 moves to a height that aligns the center of the suitcase with the height of the sewing end 3 of the sewing device 2. At this point, the longer edge of the suitcase is positioned at the sewing end 3 of the sewing device 2. The sewing device 2 continues to sew the zipper onto the longer edge of the suitcase, while the moving seat 6 moves backward until the zipper is sewn at the predetermined position on the longer edge of the suitcase. In this way, the suitcase zipper sewing equipment completes the zipper sewing operation for the suitcase.

[0041] Understandably, since the luggage mounting mechanism 12 can position the center of the luggage relative to the rotation center of the mounting plate 10, the stitching trajectory of the four arc corners changes regularly when sewing the zipper on the luggage. Therefore, the luggage zipper sewing equipment can be programmed to execute, thereby achieving automated control of the luggage zipper sewing operation.

[0042] In the process of sewing the zipper onto the suitcase using the complete zipper sewing equipment, since the first coordinate linear reciprocating motion mechanism 8 is not attached to the rotating mounting plate 10, it moves as a whole during operation. Therefore, the control line used to control the operation of the first coordinate linear reciprocating motion mechanism 8 will not become tangled, thus reducing the risk of fatigue breakage and ensuring reliable operation of the complete zipper sewing equipment. Furthermore, because the control line does not become tangled, there is no need for an unwinding step after sewing the zipper onto the suitcase, thereby improving production efficiency.

[0043] In this embodiment, the suitcase mounting mechanism 12 includes a suction cup 13, which is fixed to the mounting plate 10. The suction cup 13 is connected to a vacuum pump via a solenoid valve, and the controller controls the operation of the solenoid valve. In practical applications, the side of the suitcase facing away from the opening is placed on the suction cup 13, and the solenoid valve is controlled to connect the vacuum pump to the suction cup 13, generating a vacuum on the suction cup 13, thereby fixing the suitcase on the auxiliary sewing mechanism 5. Since the suitcase is fixed using the property of vacuum adsorption, it is convenient for loading and unloading the suitcase on the suitcase zipper sewing equipment. It should be noted that the suitcase mounting mechanism 12 can also adopt other implementation structures.

[0044] In this embodiment, the suitcase mounting mechanism 12 is designed to position the center of the suitcase relative to the rotation center of the mounting plate 10. Typically, two suction cups 13 are used, symmetrically distributed along the rotation center of the mounting plate 10. Alternatively, a single suction cup 13 may be used, with its center opposite to the rotation center of the mounting plate 10. It should be noted that the suction cups 13 can be asymmetrically distributed, but the following condition must still be met: the center of the suitcase after being fixed by the suction cups 13 is positioned relative to the rotation center of the mounting plate 10. It should be explained that in this embodiment, it is optimal for the suitcase mounting mechanism 12 to position the center of the suitcase and the rotation center of the mounting plate 10 coaxially. However, a slight deviation between the two can be compensated for by utilizing the elasticity of the suitcase itself to compensate for assembly accuracy errors, thus meeting the requirements of the suitcase zipper sewing equipment.

[0045] In this embodiment, the suitcase mounting mechanism 12 further includes a limiting plate 15, which is connected to the mounting plate 10. The inner side of the limiting plate 15 limits the suitcase receiving space 16. In practical application, the suitcase is fixed within the suitcase receiving space. The size of the suitcase receiving space 16 is adapted to the specifications of the suitcase, and after the suitcase is placed in, the portion of the suitcase near the opening is exposed outside the suitcase receiving space 16 for the sewing device 2 to sew the zipper. The center of the suitcase receiving space 16 is opposite to the rotation center of the mounting plate 10. In this embodiment, the suitcase receiving space 16 constructed by the limiting plate 15 further defines the position of the suitcase on the mounting plate 10, ensuring that the center of the suitcase is located at the rotation center of the mounting plate 10, and also reducing the accuracy requirement for the center of the suction cup 13 to be opposite to the rotation center of the mounting plate 10.

[0046] In this embodiment, the position of the limiting plate 15 is connected to the mounting plate 10 via an adjustment structure, allowing the limiting plate 15 to be movable relative to the mounting plate 10, thus adapting to different sizes of trolley cases. Typically, the adjustment structure includes an elongated groove 17 on the mounting plate 10 and mounting holes 18 on the limiting plate 15. The limiting plate 15 is fixed to the mounting plate 10 using fasteners, such as bolts and nuts. In another embodiment, the elongated groove 17 can also be provided on the limiting plate 15, and correspondingly, the mounting holes 18 can be provided on the mounting plate 10.

[0047] The output end of the movable seat can reciprocate along the sewing direction, and the output end of the movable seat is controlled by a coordinate-type linear reciprocating motion mechanism to reciprocate along the sewing direction. In this embodiment, as shown in the figure, the movable seat 6 is a cross-shaped movable seat 6, which includes a second coordinate-type linear reciprocating motion mechanism 19, a third coordinate-type linear reciprocating motion mechanism 20, a first assembly table 21, and a second assembly table 22. In this embodiment, the first coordinate-type linear reciprocating motion mechanism 8 and the second coordinate-type linear reciprocating motion mechanism 19 adopt a linear module structure. The linear module includes a lead screw pair, a guide rail pair, a drive device, etc., and the drive device is connected to the lead screw pair for transmission. Of course, other types of modules can also be used to construct the cross-shaped movable seat 6.

[0048] The output end of the second coordinate linear reciprocating motion mechanism 19 is connected to the first assembly table 21. The third coordinate linear reciprocating motion mechanism 20 is installed on the first assembly table 21, and its output end is connected to the second assembly table 22, thus constructing the cross-shaped moving base 6. The second coordinate linear reciprocating motion mechanism 19 is positioned along the sewing direction. The controller controls the operation of the second coordinate linear reciprocating motion mechanism 19 and the third coordinate linear reciprocating motion mechanism 20. As shown in the figure, the second coordinate linear reciprocating motion mechanism 19 is installed on the frame 1. The nut in the second coordinate linear reciprocating motion mechanism is connected to the first assembly table 21, and the slider of the guide rail pair in the second coordinate linear reciprocating motion mechanism is connected to the first assembly table 21. The second coordinate linear reciprocating motion mechanism 19 drives the first assembly table 21 to move along the sewing direction. The lead screw pair, guide rail pair, and drive device of the third coordinate linear reciprocating motion mechanism 20 are mounted on the second assembly table 22. The nut in the third coordinate linear reciprocating motion mechanism is connected to the second assembly table 22, and the slider of the guide rail pair in the third coordinate linear reciprocating motion mechanism is connected to the second assembly table 22. The movement direction of the third coordinate linear reciprocating motion mechanism is perpendicular to the movement direction of the second coordinate linear reciprocating motion mechanism 19. That is, the third coordinate linear reciprocating motion mechanism controls the second assembly table 22 to move closer to and further away from the side of the sewing device 2. Correspondingly, the trolley case mounting mechanism 12 can approach and move away from the sewing end 3 of the sewing device 2. When the trolley case mounting mechanism 12 is close to the sewing end 3 of the sewing device 2, the trolley case can accept the sewing operation of the sewing device 2. When the trolley case mounting mechanism 12 is far away from the sewing end 3 of the sewing device 2, the trolley case can be placed into the trolley case mounting mechanism 12 and the trolley case can be removed. In this embodiment, the third coordinate type linear reciprocating motion mechanism 20 can also be replaced by a cylinder, guide rail pair or other structures.

[0049] As an implementation of the cross-shaped moving seat 6, the third coordinate type linear reciprocating motion mechanism 20 can also be set along the sewing direction. Correspondingly, the second coordinate type linear reciprocating motion mechanism 19 is used to control the trolley case mounting mechanism 12 to approach and move away from the sewing end 3 of the sewing device 2.

[0050] The movable seat 6 can be configured to move along the sewing direction, and its output end is controlled by a coordinate-type linear reciprocating motion mechanism to reciprocate along the sewing direction. A further implementation of this movable seat structure can be as follows: the movable seat 6 includes a second coordinate-type linear reciprocating motion mechanism 19 and a first assembly table 21. The second coordinate-type linear reciprocating motion mechanism 19 is positioned along the sewing direction, and its output end is connected to the first assembly table 21. A first mounting bracket 7 is mounted on the first assembly table 21. To facilitate loading and unloading, the output end of a third coordinate-type linear reciprocating motion mechanism is connected to the second assembly table, which is used for mounting the sewing device. Thus, during loading and unloading, the sewing device 2 can be driven to approach or move away from the auxiliary sewing mechanism 5. Correspondingly, the pull-luggage mounting mechanism can approach or move away from the sewing end of the sewing device along the axial direction of the mounting plate.

[0051] In the above embodiments, the first coordinate linear reciprocating motion mechanism, the second coordinate linear reciprocating motion mechanism, and the third coordinate linear reciprocating motion mechanism are replaced by linear motors or servo cylinders.

[0052] In this embodiment, the guiding mechanism includes a guide 23 with a material groove 24. In practical applications, the material groove 24 allows the zipper to pass through and guides it. A connecting platform 25 is provided on the guide 23. In this embodiment, the connecting platform 25 is located at the inlet end of the guide 23. Of course, the connecting platform 25 can also be located in other positions, such as the middle of the guide 23 or other locations. A clamping block 26 is provided corresponding to the position of the connecting platform 25. A clamping drive mechanism 27 controls the clamping block 26 to move away from or towards the connecting platform 25; a controller controls the operation of the clamping drive mechanism 27. In this embodiment, the clamping drive mechanism 27 is a cylinder. In practical applications, the zipper passes between the clamping block 26 and the connecting table 25. When the clamping drive mechanism 27 controls the clamping block 26 to approach the connecting table 25, the zipper is clamped between the connecting table 25 and the clamping block 26, thereby locking the zipper onto the guide 23. During the process of the sewing device 2 sewing the zipper and the trolley case together, when the clamping drive mechanism 27 controls the clamping block 26 to move away from the connecting table 25, the clamping block 26 releases the lock on the zipper. At this time, the zipper can pass through the bottom of the clamping block 26 and the guide 23 to lift the zipper material into the zipper sewing operation.

[0053] In this embodiment, the guide 23 is connected to the output end of the fourth linear reciprocating motion mechanism 28. The fourth linear reciprocating motion mechanism 28 positions the guide 23 both close to and away from the sewing end 3 of the sewing device 2. The controller controls the operation of the fourth linear reciprocating motion mechanism 28. Typically, the fourth linear reciprocating motion mechanism 28 is a pneumatic slide. Of course, other structures can also be used.

[0054] In practical applications, the fourth linear reciprocating motion mechanism 28 works in conjunction with the clamping drive mechanism 27. When the clamping drive mechanism 27 controls the clamping block 26 to approach the connecting table 25, the fourth linear reciprocating motion mechanism 28 controls the guide 23 to move towards the sewing end 3 of the sewing device 2, so that the guide 23 is close to the sewing end 3 of the sewing device 2, thereby pulling the zipper to the sewing end 3 of the sewing device 2. Afterwards, the clamping drive mechanism 27 controls the clamping block 26 to move away from the connecting table 25. Before the first cutting mechanism 29 cuts the zipper, the fourth linear reciprocating motion mechanism 28 controls the guide 23 to move away from the sewing end 3 of the sewing device 2, preparing for the next round of zipper feeding.

[0055] In this embodiment, the guide 23 is inclined, and the fourth linear reciprocating motion mechanism 28 is also inclined in its direction of movement. As shown in the figure, the guide 23 and the fourth linear reciprocating motion mechanism 28 are lower at one end and higher at the other end near the sewing device 2. Because they are inclined, it facilitates the transport of the zipper to the sewing end 3 of the sewing device 2. Furthermore, due to the inclined arrangement, the guide will not scratch the surface of the suitcase, ensuring the integrity of the suitcase.

[0056] In this embodiment, the fourth linear reciprocating motion mechanism 28 is mounted on the bracket 36, and the relative angle of the bracket 36 is adjustablely mounted on the base 37, so that the tilt angle of the guide 23 and the fourth linear reciprocating motion mechanism 28 can be adjusted as a whole.

[0057] In this embodiment, a first groove 38 and a second groove 39 are provided on the base 37, and a hole 40 and an arc-shaped groove 41 are provided on the bracket 36. The hole 40 and the first groove 38 are opposite each other for connection with a first fastener, and the arc-shaped groove 41 and the second groove 39 are opposite each other for connection with a second fastener. This structure allows the height of the guide relative to the base 37 to be adjusted, and the angle relative to the base 37 can also be adjusted.

[0058] As shown in the figure, it also includes a first cutting mechanism 29, which can typically be an electric or pneumatic shear. The first cutting mechanism 29 is used to cut the zipper. The first cutting mechanism 29 is located on the front side of the sewing device 2 and is mounted on the output end of the fifth linear reciprocating motion mechanism 30. Typically, the fifth linear reciprocating motion mechanism 30 uses a pneumatic slide or the like. In a specific application, the fourth linear reciprocating motion mechanism 28 controls the guide 23 to move away from the sewing end 3 of the sewing device 2, and the clamping drive mechanism 27 controls the clamping block 26 to approach the connecting table 25 to lock the zipper. Then, the first cutting mechanism 29, which is extended by the fifth linear reciprocating motion mechanism 30, cuts the zipper, and then the fifth linear reciprocating motion mechanism 30 resets.

[0059] As shown in the figure, a second cutting mechanism 31 is also included. Typically, the second cutting mechanism 31 can be an electric or pneumatic shear. The second cutting mechanism 31 is used to cut the thread and is mounted on the side of the sewing device 2 via a sixth linear reciprocating motion mechanism 32. Typically, the sixth linear reciprocating motion mechanism 32 is a pneumatic slide or similar device. In practical applications, after the zipper is sewn onto the suitcase, the third coordinate-type linear reciprocating motion mechanism 20 controls the mounting plate 10 to move away from the sewing device 2. The second cutting mechanism 31, extended by the sixth linear reciprocating motion mechanism 32, cuts the thread, and then the sixth linear reciprocating motion mechanism 32 returns to its original position.

[0060] In this embodiment, a stop plate 33 is also included, which is installed at a position corresponding to the sewing end 3 of the sewing device 2. The stop plate extends upward from below the sewing device. As shown in the figure, the stop plate 33 is fixed to the frame 1, with most of its area located below the sewing end 3. In practical applications, the stop plate 33 is used to abut against the open end of the suitcase, preventing the suitcase from shifting improperly. Since suitcases are usually made of ABS or other plastic materials, they are prone to deformation under certain stress. During the sewing process, because the stop plate 33 is positioned on the suitcase, the suitcase can be sewn by the sewing device 2 with the stop plate 33 as a reference position, ensuring that the zipper is always sewn in the predetermined position, resulting in a straighter seam.

[0061] In one embodiment, a rotatable roller 34 is provided on the abutment plate 33. As shown in the figure, the abutment plate 33 is provided with a rotatable roller 34, which is used by the suitcase to abut against. In this embodiment, the roller 34 is arranged along the height direction. In another embodiment, the roller 34 may also be arranged along the lateral direction. Since the roller 34 is rotatable, it facilitates the rotation of the suitcase mounting mechanism 12 with the suitcase.

[0062] In this embodiment, the upper end of the abutment plate 33 is provided with a notch 35 for the sewing end 3 of the sewing device 2 to be received, and the upper end of the roller 34 extends to or beyond the sewing end 3 of the sewing device 2. In practical applications, the suitcase can make more comprehensive contact with the roller 34, avoiding unilateral tilting of the suitcase and ensuring that the seam sewn on the suitcase is straighter.

[0063] This utility model also provides a method for sewing a zipper on a suitcase using a complete set of sewing equipment. The method includes: a suitcase fixing step, where the suitcase is fixed to a suitcase mounting mechanism 12, with the center of the suitcase aligned with the center of the mounting plate; a traction step, where the zipper is pulled to the sewing end 3 of the sewing device 2; a straight-line sewing step, where the sewing device 2 sews the zipper along the straight edge of the suitcase, while a second coordinate-type linear reciprocating motion mechanism operates to move the suitcase mounting mechanism 12 backward, carrying the suitcase and matching the sewing speed of the sewing device 2; and an arc-angle sewing step, where arc-angle sewing is performed... The controller controls the mounting plate 10 to rotate and simultaneously controls the moving seat 6 to move forward. During the forward movement of the moving seat, the controller first controls the first coordinate linear reciprocating motion mechanism 8 to move the second mounting frame 9 downward, and then controls the first coordinate linear reciprocating motion mechanism 8 to move the second mounting frame 9 upward, adapting to the change in the distance between the center of the trolley case and the sewing end of the sewing device. In the cutting step, the controller controls the fifth linear reciprocating motion mechanism 30 to work so that the first cutting mechanism 29 cuts the zipper, and the controller controls the sixth linear reciprocating motion mechanism 32 to work so that the second cutting mechanism 31 works to cut the thread.

[0064] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
