Description

Technical Field

[0001] This utility model relates to the technical field of strapping guide structure for fully automatic packaging machines, and particularly to a strapping guide structure for a fully automatic packaging machine. Background Technology

[0002] The strapping guide structure of a fully automatic strapping machine is a core component that ensures the stable transmission and precise positioning of the strapping (usually plastic or steel strapping) during the strapping process. Its design directly affects the strapping efficiency, strapping quality, and equipment stability.

[0003] Existing fully automatic strapping machines may have issues with their strapping guide structures, such as manual adjustment of the guide wheel spacing, poor adaptability between the guide wheel spacing and the strapping width, and low versatility. In actual use, manual adjustment of the guide wheel spacing can lead to inconsistent adjustment accuracy and asymmetry when no auxiliary tools are available. Furthermore, if a fixed-spacing wheel is used, narrow strapping may wobble due to excessive gaps when using strapping of different widths, while wide strapping may be squeezed by the wheel edge, resulting in strap deformation, wear, or even breakage. To address these issues, we propose a strapping guide structure for fully automatic strapping machines. Utility Model Content

[0004] The purpose of this utility model is to provide a strapping guide structure for a fully automatic strapping machine, in order to solve the problems mentioned in the background art, such as the need for manual adjustment of the guide wheel spacing, poor adaptability of the guide wheel spacing to the strapping width, and low versatility. In actual use, manual adjustment of the guide wheel spacing can lead to inconsistent adjustment accuracy, and asymmetry may easily occur when there are no auxiliary tools. Furthermore, if a fixed spacing wheel is used, when using strapping of different widths, the narrow strap may wobble left and right due to the large gap, and the wide strap may be squeezed by the edge of the wheel, resulting in deformation, wear, or even breakage of the strap.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a strapping guide structure for a fully automatic strapping machine, comprising a base plate and a strapping body. A fixing plate is fixedly installed on the top of the base plate, and a guide assembly is provided on the outside of the fixing plate. The guide assembly includes a ruler, a fixing frame, and a guide rod. A rectangular groove is formed on the front surface of the fixing plate. The ruler is fixedly installed on the front side of the fixing plate and located above the rectangular groove. The fixing frame is connected to a bidirectional lead screw via a motor. The bidirectional lead screw is connected to a connecting piece via a moving block. The connecting piece is connected to an axle and a fixed wheel via a rotating rod. The axle is connected to an adjusting wheel via bolts.

[0006] As a preferred embodiment, the fixing frame is fixedly installed on the rear surface of the fixing plate, the motor is fixedly installed on the left side surface of the fixing frame, one end of the bidirectional lead screw is fixedly connected to the output end of the motor, the other end of the bidirectional lead screw is rotatably connected to the right inner wall of the fixing frame, and the outer wall of the bidirectional lead screw is rotatably connected to the left inner wall of the fixing frame.

[0007] As a preferred embodiment, the guide rod is fixedly installed on the inner walls of both sides of the fixed frame, one end of the inner wall of the movable block is slidably connected to the outer wall of the guide rod, the other end of the inner wall of the movable block is threadedly connected to the outer wall of the bidirectional lead screw, the rear end of the connector is fixedly connected to the outer wall of the movable block, one end of the rotating rod is rotatably connected to the inside of the connector, and the other end of the rotating rod is fixedly connected to the wheel axle.

[0008] As a preferred embodiment, the fixed wheel is fixedly connected to the outer wall of the axle, and the outer wall of the axle has multiple sets of threaded holes distributed at equal intervals. The adjusting wheel is threadedly connected to the outer wall of the axle by bolts, the bolts being adapted to the threaded holes. The strapping body is in contact with the surface of the axle, and the strapping body is located between the fixed wheel and the adjusting wheel.

[0009] As a preferred embodiment, an impurity scraping assembly is provided above the main body of the strapping band. The impurity scraping assembly includes a load-bearing plate, a hydraulic rod is fixedly installed on the top of the load-bearing plate, and a connecting plate is fixedly installed on the lower end of the hydraulic rod.

[0010] As a preferred embodiment, a scraper is fixedly installed at the bottom of the connecting plate, a connecting arm is fixedly installed at the top of the connecting plate, a fixing rod is slidably connected to the upper inner wall of the connecting arm, the fixing rod is fixedly installed at the top of the load-bearing plate, and the bottom of the scraper is in contact with the surface of the strapping body.

[0011] The technical effects and advantages of this utility model are as follows: With the set guide components, the staff starts the motor, drives the bidirectional lead screw to rotate, and drives the moving block to slide along the guide rod. This allows for flexible adjustment of the distance between the two sets of guide wheels, which consist of a fixed wheel, a wheel axle, and an adjusting wheel. This changes the contact pressure and transmission friction between the strapping body and the guide wheels, helping to control the tension and preventing breakage due to excessive tightness or instability due to excessive looseness. At the same time, the position of the adjusting wheel can be adjusted by the cooperation of the bolts and the threaded holes on the wheel axle, changing the distance between the fixed wheel and the adjusting wheel, adapting to strapping bodies of different widths, and improving the versatility and adaptability of the guide structure. With the impurity scraping component in place, the hydraulic rod can drive the connecting plate and scraper to move up and down, so that the bottom of the scraper makes close contact with the surface of the strapping. This can effectively scrape off the impurities attached to the surface. At the same time, the connecting arm slides along the fixed rod to ensure that the scraper is stable and does not deviate during the lifting and lowering process. This not only ensures the impurity scraping effect, but also avoids the scraper from excessively squeezing or deviating and damaging the strapping, thereby reducing the interference of impurities on subsequent packaging processes and improving packaging quality.

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.

[0015] Please see the appendix Figure 1 - Appendix Figure 4A strapping guide structure for a fully automatic packaging machine includes a base plate 1 and a strapping body 3. A fixing plate 2 is fixedly installed on the top of the base plate 1. A guide assembly 4 is provided on the outside of the fixing plate 2. The guide assembly 4 includes a scale 402, a fixing frame 403 and a guide rod 414. A rectangular groove 401 is opened on the front surface of the fixing plate 2. The scale 402 is fixedly installed on the front side of the fixing plate 2 and located above the rectangular groove 401. The fixing frame 403 is connected to a bidirectional lead screw 405 through a motor 404. The bidirectional lead screw 405 is connected to a connector 407 through a moving block 406. The connector 407 is connected to an axle 409 and a fixed wheel 410 through a rotating rod 408. The axle 409 is connected to an adjusting wheel 412 through bolts 413.

[0016] The scale 402 is used to visually display the distance between the two sets of guide wheels and the position of the adjustment wheel 412, assisting the operator to quickly and accurately complete the distance adjustment. The rectangular groove 401 is opened on the front side of the fixed plate 2, which can provide space for the connector 407 to move with the moving block 406, and avoid the fixed plate 2 from interfering with the movement of the guide assembly 4.

[0017] The fixed frame 403 is fixedly installed on the rear surface of the fixed plate 2. The motor 404 is fixedly installed on the left side surface of the fixed frame 403. One end of the bidirectional lead screw 405 is fixedly connected to the output end of the motor 404. The other end of the bidirectional lead screw 405 is rotatably connected to the right inner wall of the fixed frame 403. The outer wall of the bidirectional lead screw 405 is rotatably connected to the left inner wall of the fixed frame 403. The guide rod 414 is fixedly installed on both inner walls of the fixed frame 403. One end of the inner wall of the moving block 406 is slidably connected to the outer wall of the guide rod 414. The other end of the inner wall of the moving block 406 is threadedly connected to the outer wall of the bidirectional lead screw 405. The rear end of the connecting piece 407 is fixedly connected to the outer wall of the moving block 406. One end of the rotating rod 408 is rotatably connected to the inside of the connecting piece 407. The other end of the rotating rod 408 is fixedly connected to the axle 409.

[0018] The movable block 406, the connecting piece 407, the rotating rod 408, the axle 409, the fixed wheel 410, the adjusting wheel 412 and the bolt 413 are each provided in two sets. The fixed wheel 410, the axle 409 and the adjusting wheel 412 form a guide wheel. The two-way screw 405 can adjust the distance between the two sets of guide wheels.

[0019] The fixed wheel 410 is fixedly connected to the outer wall of the axle 409. The outer wall of the axle 409 has multiple sets of threaded holes 411 that are evenly distributed. The adjusting wheel 412 is threadedly connected to the outer wall of the axle 409 by bolts 413. The bolts 413 are adapted to the threaded holes 411. The strapping body 3 is in contact with the surface of the axle 409. The strapping body 3 is located between the fixed wheel 410 and the adjusting wheel 412.

[0020] The axle 409 serves as the mounting shaft for both the fixed wheel 410 and the adjusting wheel 412, and it also directly contacts the strapping body 3, guiding the transmission path of the strapping body 3. The threaded hole 411 on its outer wall is used to fix the position of the adjusting wheel 412.

[0021] Specifically, through the set guide component 4, the operator starts the motor 404, drives the bidirectional lead screw 405 to rotate, and drives the moving block 406 to slide along the guide rod 414. This allows for flexible adjustment of the distance between the two sets of guide wheels, consisting of a fixed wheel 410, a wheel axle 409, and an adjusting wheel 412. This changes the contact pressure and transmission friction between the strapping body 3 and the guide wheels, assisting in controlling the tension and preventing breakage due to excessive tightness or instability due to excessive looseness. At the same time, through the cooperation of the bolt 413 and the threaded hole 411 on the wheel axle 409, the position of the adjusting wheel 412 can be adjusted, changing the distance between the fixed wheel 410 and the adjusting wheel 412. This adapts to strapping bodies 3 of different widths, improving the versatility and adaptability of the guide structure.

[0022] Please see the appendix Figure 1 and appendix Figure 5 An impurity scraping component 5 is provided above the main body 3 of the strapping band. The impurity scraping component 5 includes a load-bearing plate 501. A hydraulic rod 502 is fixedly installed on the top of the load-bearing plate 501, and a connecting plate 503 is fixedly installed on the lower end of the hydraulic rod 502.

[0023] The top of the load-bearing plate 501 has two sets of hollow slots, which allow the outer wall of the hydraulic rod 502 to slide up and down and the connecting arm 505 to move up and down. The connecting plate 503 can transmit the driving force of the hydraulic rod 502 to the scraper 504 and fix the connecting arm 505 to ensure the stability of the scraper 504 when it is raised and lowered.

[0024] A scraper 504 is fixedly installed at the bottom of the connecting plate 503, and a connecting arm 505 is fixedly installed at the top of the connecting plate 503. A fixing rod 506 is slidably connected to the inner wall of the upper end of the connecting arm 505. The fixing rod 506 is fixedly installed on the top of the load-bearing plate 501. The bottom of the scraper 504 is in contact with the surface of the strapping body 3.

[0025] The fixing rod 506 is fixed to the top of the load-bearing plate 501, providing a sliding guide for the connecting arm 505. Together with the hydraulic rod 502, it ensures the straightness and stability of the scraper 504 during the lifting process, and at the same time limits the connecting arm 505 to prevent the scraper 504 from moving too far down and avoids damage to the strapping body 3.

[0026] Specifically, through the impurity scraping component 5, the hydraulic rod 502 can drive the connecting plate 503 and the scraper 504 to move up and down, so that the bottom of the scraper 504 is in close contact with the surface of the strapping body 3, which can effectively scrape off the impurities attached to its surface. At the same time, the connecting arm 505 slides along the fixed rod 506 to ensure that the scraper 504 is stable and does not deviate during the lifting process, ensuring the impurity scraping effect, avoiding excessive squeezing or deviation of the scraper 504 that could damage the strapping body 3, reducing the interference of impurities on subsequent packaging processes, and improving packaging quality.

[0027] Working principle of this utility model: This utility model is a strapping guide structure for a fully automatic strapping machine. First, the operator adjusts the distance between the adjusting wheel 412 and the fixed wheel 410 according to the width of the strapping body 3, through the cooperation of the bolt 413 and the threaded hole 411 on the wheel axle 409, so that the strapping body 3 can be stably placed between them. Then, referring to the scale 402, the operator starts the motor 404 to drive the bidirectional lead screw 405 to rotate, causing the moving block 406 to slide along the guide rod 414, thereby adjusting the distance between the two sets of guide wheels to adapt to the tension requirements of the strapping body 3 during transmission. During this process, the connecting piece 407 moves with the moving block 406. Moving within the rectangular groove 401, the rotating rod 408 can rotate flexibly to adapt to the transmission direction. After the guide adjustment is completed, the operator activates the hydraulic rod 502 to drive the connecting plate 503 and the scraper 504 to move downward, so that the bottom of the scraper 504 contacts the surface of the strapping body 3. At the same time, the connecting arm 505 slides along the fixed rod 506 to ensure that the scraper 504 is stable and does not deviate. When the strapping body 3 is transmitted, the axle 409 guides it to move along the preset path, and the fixed wheel 410 and the adjusting wheel 412 limit its lateral deviation. The scraper 504 simultaneously scrapes away surface impurities, ultimately achieving stable guidance and clean transmission of the strapping, ensuring the smooth progress of subsequent packaging processes.

[0028] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
