[0002] A trolley case is a portable suitcase that is usually equipped with a retractable handle and wheels, which makes it easy for users to carry and drag it when traveling. Trolley cases are popular for their convenience, durability and moderate capacity. In order to facilitate the taking and placing of items, existing trolley cases are often provided with a zipper around the body for opening and closing the trolley case body. Therefore, the zipper of the trolley case needs to be sewn during the production process of the trolley case, and a zipper sewing device for the trolley case is needed here.

[0003] For example, a zipper sewing device for producing a trolley case disclosed in a Chinese patent with publication number CN220224544U includes an operating table and a support plate, wherein the support plate is L-shaped and a fixing structure is arranged on the support plate. The rotation of the threaded rod 2 drives the support plate to move in the horizontal direction, and the movement of the support plate drives the trolley case to move in the lateral direction. The sewing machine head performs zipper sewing processing on the trolley case through the sewing machine. By fixing the trolley case, the position displacement of the trolley case during the sewing process is avoided, and the stability of the zipper sewing processing of the trolley case is ensured. By driving the support plate to move in the lateral direction, the trolley case is driven to move, and the entire side of the trolley case can be sewn, and there is no need to manually push the trolley case to move, which saves trouble and labor and is more convenient to operate.

[0004] Since the zipper of a suitcase is often wrapped around the entire body, and the utility model patent only provides a structure for fixing the suitcase, but does not provide a mechanism for adjusting the angle of the suitcase, the device can only sew the zipper on a single side of the suitcase. After completing this side, the worker needs to manually adjust the position of the suitcase before sewing the zipper on the other side of the suitcase. Multiple adjustments are required to complete the sewing of the four sides, and the process is relatively cumbersome and the production efficiency is low.

[0005] Based on the above, the purpose of the present invention is to provide a zipper sewing device for producing a trolley case to solve the above problems. Utility Model Content

[0024] The utility model is described in detail below in conjunction with the accompanying drawings.

[0025] A zipper sewing device for producing a trolley case, such as Figure 1-Figure 3 As shown, it includes a fixed frame 1, on which a sewing module is provided, and the sewing module includes a table top 2 and a sewing machine body 3 fixedly connected to the fixed frame, a mounting frame 4 is slidably connected to the fixed frame 1, and a first driving mechanism for driving the mounting frame 4 to move is provided on the fixed frame 1, and an operating table 5 is rotatably connected to the mounting frame 4, and the operating table is circular, and the center line of the operating table 5 is on the same straight line as the center line of the upper end surface of the table top 2, a first linear module 6 is fixedly connected to the operating table 5, and a second linear module 7 is fixedly connected to the moving end of the first linear module 6, and a clamp for fixing the box 16 is provided on the moving end of the second linear module 7, and a second driving mechanism for driving the operating table 5 to rotate is provided on the mounting frame 4.

[0026] Furthermore, the second driving mechanism includes a motor 8 , on which a reducer 9 is mounted, the reducer is fixedly connected to the mounting frame, the output shaft of the motor 8 is fixedly connected to the input end of the reducer 9 , and the output shaft of the reducer 9 is fixedly connected to the operating table 5 .

[0027] Furthermore, a sensor 10 is installed on the mounting frame 4 , and the sensor is a proximity sensor. Four sensing points 11 cooperating with the sensor 10 are distributed in a circular array on one side of the operating table 5 close to the sensor 10 .

[0028] Furthermore, the clamp is an electromagnet 12 , and a clamping block 13 is adsorbed on the electromagnet 12 .

[0029] Furthermore, a buffer pad 14 is fixedly connected to the side where the electromagnet 12 and the clamping block 13 are close to each other.

[0030] Furthermore, the first driving mechanism is an electric push rod 15 fixedly connected to the fixing frame 1 , and the extended end of the electric push rod 15 is fixedly connected to the mounting frame 4 .

[0031] Furthermore, the upper end surface of the table top 2 is arranged in an arc shape.

[0032] Working principle: When it is necessary to sew the zipper of the box body 16 of the trolley case, the box body 16 is fixed to the moving end of the second linear module 7 by the electromagnet 12 and the clamping block 13. The buffer pad 14 will prevent the box body 16 from being scratched. Then the electric push rod 15 is used to drive the box body 16 to approach the sewing module until the inner wall of the side wall of the box body 16 is placed on the upper end surface of the table 2. Then the worker puts the zipper on the box body 16, and then sews the box body 16 and the zipper through the sewing machine body 3. At this time, the first linear module 6 is driven to drive the box body 16 to move, and then the zipper is sewn on this side of the box body 16.

[0033] When sewing to the intersection of the two sides of the box 16, if the intersection is a right angle, the operating table 5 can be driven to rotate by the motor 8 and the reducer 9, thereby driving the box 16 to rotate 90 degrees around the table 2, and then the position can be adjusted by the first linear module or the second linear module to continue the sewing operation. The motor 8 and the reducer 9 can reduce the rotation speed of the box 16 to prevent the box 16 from being displaced due to inertia due to excessive speed, and can also increase the driving torque. The sensor 10 will determine whether the operating table 5 is rotated into place by detecting the position of the sensing point. When the sensor 10 detects that the operating table 5 is rotated into place, the motor 8 can be controlled to stop running to ensure the rotation accuracy of the operating table 5. The above-mentioned electronic components can be controlled by setting a PLC controller. How to use a PLC controller to control electronic components is a mature existing technology and will not be elaborated here.

[0034] When the junction is in an arc shape, the position of the box 16 is adjusted by the first linear module or the second linear module while driving the operating table 5 to rotate, so that the sewing machine body 3 can sew the zipper on the arc-shaped junction. The arc-shaped upper end surface of the table top 2 can reduce the friction of the table top 2 on the inner wall of the box 16, and prevent the arc surface of the inner wall of the box 16 from being scratched. With this arrangement, when sew the zipper of the trolley case, the worker does not need to manually adjust the position of the box 16, which saves time and effort and is more convenient to operate.

[0035] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
