Description

Technical Field

[0001] This utility model relates to the field of ton bag processing technology, specifically a thread trimming device for an automatic ton bag sewing machine. Background Technology

[0002] Ton bags are flexible packaging containers used for the transportation and storage of bulk materials. Automatic sewing machines for ton bags are industrial equipment specifically designed to sew the openings of these bags. Through sewing technology, the openings are tightly sealed to ensure airtightness and strength. Suitable for materials such as plastic woven bags and paper bags, ton bags, as load-bearing packaging, require high-strength stitching. Neat, appropriately sized thread ends are a reflection of the process standards and prevent the threads from getting caught or coming loose under load. However, the stitching material for ton bags is thick and heavy, making manual cutting time-consuming and laborious. Furthermore, excessively long thread ends may get caught during subsequent handling, stacking, and use, causing safety hazards or packaging damage. Automatic trimming can maintain product cleanliness. To improve the efficiency of automatic sewing machines for ton bags, a synchronous thread trimming device is needed. However, existing synchronous thread trimming devices still have the following shortcomings. When using existing thread trimming devices, most of them cannot efficiently identify thread ends, causing them to mistakenly identify non-thread ends as thread ends and perform unnecessary cutting. If the cutting reaches the main body of the ton bag, it can easily cause holes or scratches, resulting in product scrap. Cutting into thick fabric areas or cutting into empty areas can accelerate the wear and dulling of the blades, thus consuming additional air and electricity, increasing operating costs, and causing a decrease in the practicality and efficiency of the thread trimming device.

A limiting slider is added to the inner side of the fixing block, and a limiting through hole is opened inside the limiting slider. A limiting rod is connected inside the limiting through hole. A detection assembly is disposed on the outer right side of the mounting base.

[0005] Furthermore, the gear meshes with the gear rack, and the gear rack is slidably connected to the mounting block via the gear.

[0007] Furthermore, the internal dimensions of the limiting through hole are adapted to the external dimensions of the limiting rod, and the limiting rod is embeddedly connected to the limiting slider through the limiting through hole.

[0008] Furthermore, the detection component includes a mounting bracket, fixing bolts, and a receiving bracket. The mounting bracket is internally connected to the fixing bolts, and the receiving bracket is installed at the front end of the mounting bracket.

[0009] Furthermore, the detection assembly also includes a movable rotating shaft, a damping rotating shaft, and an industrial camera.

[0016] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0017] like Figures 1 to 4As shown, a thread trimming device for an automatic sewing machine for ton bags includes a mounting base 1 and a trimming assembly 3. The sewing machine body 2 is mounted on the upper left side of the mounting base 1. The trimming assembly 3 is located on the outer side of the sewing machine body 2. The trimming assembly 3 includes a mounting block 301, a servo motor 302, a gear 303, a gear rack 304, a fixing block 305, a blade 306, a limiting slider 307, a limiting through hole 308, and a limiting rod 309. The servo motor 302 is mounted on the outside of the mounting block 301, and a gear is connected to the front end of the servo motor 302. The gear 303 has a gear rack 304 connected to its upper end. A fixing block 305 is mounted on the upper end of the gear rack 304. A blade 306 is provided on the upper end of the fixing block 305. A limiting slider 307 is added to the inner side of the fixing block 305. A limiting through hole 308 is opened inside the limiting through hole 308. A limiting rod 309 is connected inside the limiting through hole 308. The gear 303 meshes with the gear rack 304. The gear rack 304 is slidably connected to the mounting block 301 through the gear 303. The blade 306 is perpendicular to the fixing block 305. The blade 306 is fixedly connected to the fixing block 305 by bolts. The internal dimensions of the limiting through hole 308 are adapted to the external dimensions of the limiting rod 309, and the limiting rod 309 is embeddedly connected to the limiting slider 307 through the limiting through hole 308. The servo motor 302 is fixedly mounted on the outside of the mounting block 301 by fastening bolts. The output shaft of the servo motor 302 is connected to a gear 303 through a coupling. The operation of the servo motor 302 drives the gear 303 to rotate, causing the gear rack 304 connected to the outside of the gear 303 to move accordingly. The fixed block 305 installed on the upper end of the toothed row 304 is adjusted left and right. The internal size of the limiting through hole 308 opened in the external limiting slider 307 of the fixed block 305 is adapted to the external size of the limiting rod 309. Thus, the limiting through hole 308 and the limiting rod 309 are used to increase the stability of the limiting slider 307 during movement, thereby preventing the blade 306 at the upper end of the fixed block 305 from shifting position. The movement of the blade 306 is used to trim the thread ends of the ton bag simultaneously, thereby improving the overall practicality and efficiency of the thread end trimming device.

[0018] like Figure 1 , Figure 3 and Figure 4As shown, a detection component 4 is provided on the outer right side of the mounting base 1. The detection component 4 includes a mounting bracket 401, a fixing bolt 402, and a receiving bracket 403. The fixing bolt 402 is connected inside the mounting bracket 401, and the receiving bracket 403 is installed at the front end of the mounting bracket 401. The detection component 4 also includes a movable rotating shaft 404, a damping rotating shaft 405, and an industrial camera 406. The movable rotating shaft 404 is installed on the upper end of the receiving bracket 403, and the damping rotating shaft 405 is provided on the upper end of the movable rotating shaft 404. The industrial camera 406 is installed on the upper end of the damping rotating shaft 405. The fixing bolt 402 is embeddedly connected to the mounting bracket 401, and the mounting bracket 401 is fixed by... Bolt 402 is fixedly connected to mounting base 1. Industrial camera 406 and receiving frame 403 are vertically distributed, and industrial camera 406 is rotatably connected to receiving frame 403 through damping shaft 405. Mounting frame 401 is fixedly installed on the outside right side of mounting base 1 by fixing bolt 402, so that receiving frame 403 is fixed accordingly. The movable shaft 404 installed on the upper end of receiving frame 403, together with damping shaft 405, allows industrial camera 406 to be adjusted at multiple angles. Industrial camera 406 quickly captures clear images of the seam area, and in conjunction with PLC control system, adjusts the moving position of blade 306 to complete the physical cutting of seam.

[0019] In summary, the thread trimming device of this automatic sewing machine for ton bags works as follows: First, the sewing machine body 2 is fixed to the upper left side of the mounting base 1 using fastening bolts. Simultaneously, the mounting block 301 is installed on the outer front side of the sewing machine body 2 using fastening bolts. The servo motor 302 outside the mounting block 301 starts, driving the gear 303 to rotate, which in turn drives the gear rack 304 meshing with the gear 303 to move laterally. The fixing block 305 installed on the upper end of the gear rack 304 adjusts left and right accordingly to achieve precise positioning. To enhance the stability of the movement, the limiting through hole 308 cooperates with the limiting rod 309 to prevent the limiting slider 307 from shifting during movement, thereby ensuring the upper end of the fixing block 305... The blade 306 is always in the correct position and moves along the set path to achieve synchronous trimming of the sewing thread ends of the ton bag. Subsequently, the mounting bracket 401 is fixed to the right side of the mounting base 1 by the fixing bolt 402, and the receiving bracket 403 is installed in place. The upper end of the receiving bracket 403 is provided with a movable rotating shaft 404 and a damping rotating shaft 405, which allows the industrial camera 406 to be flexibly adjusted at multiple angles to adapt to different shooting needs. The industrial camera 406 is used to quickly capture clear images of the sewing area and transmit the image information to the PLC control system. The PLC system calculates the sewing position in real time based on the image data and adjusts the movement trajectory of the blade 306 accordingly, ultimately completing the precise physical cutting of the sewing thread.
