Description

Technical Field

[0001] This utility model specifically relates to a strapping machine for cardboard box packaging, belonging to the field of cardboard box packaging technology. Background Technology

[0002] A strapping machine is a device that automates product packaging and sealing. It can independently complete the entire process from conveying and strapping to inspection, aiming to improve production efficiency, reduce labor costs, and ensure consistent packaging quality. Its core functions include automatic item sensing, strapping material wrapping, tape bonding and cutting, and anomaly detection. It is widely applicable to scenarios requiring bulk packaging. Currently, most strapping machines do not consider the possibility of tape jamming caused by dust on the machine. Therefore, we propose a strapping machine for cardboard box packaging that facilitates cleaning of dust and prevents tape jamming.

[0003] Patent document CN222728320U discloses "a strapping machine for cardboard box packaging, comprising a strapping machine and a conveyor. A support plate is fixedly connected to the top left side of the strapping machine. A cylinder is fixedly connected to the outer side of the support plate. A U-shaped block is fixedly connected to the output end of the cylinder. Multiple rotating rods are rotatably connected to the bottom of the U-shaped block. A slider is rotatably connected to the bottom of each rotating rod. A sliding rod is slidably connected inside the slider. Two springs are sleeved on the outer side of the sliding rod. Each spring has a mounting box fixedly connected to both ends. In this invention, by driving the cylinder, the U-shaped block presses down, and upon contacting the cardboard box, the rotating rod rotates, thereby driving the slider to compress the springs. This achieves precise clamping of the cardboard box by the mounting box, ensuring cardboard box stability, reducing skewing, improving strapping efficiency, reducing breakage rate, and improving overall strapping quality."

[0004] However, the aforementioned published document on a strapping machine for cardboard box packaging mainly considers the problem of the straps being tied crookedly due to the shaking of the cardboard box, without taking into account the problem of dust on the strapping machine causing the straps to jam. Therefore, it is necessary to develop a strapping machine for cardboard box packaging that can prevent excessive dust from causing the straps to jam. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a strapping machine for cardboard box packaging, so as to prevent excessive dust from causing the strapping machine to jam.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a strapping machine for cardboard box packaging, comprising a strapping machine and a conveyor, wherein the conveyor is fixedly connected to one side of the strapping machine, and a dust suction structure is provided inside the strapping machine, the dust suction structure comprising a dust suction pipe, a dust filter bag, an impeller, a motor, and a clean air outlet, wherein the dust filter bag is movably connected to the rear of the dust suction pipe of the outer shell, the dust filter bag is movably connected to the outer shell, an impeller is provided inside the outer shell, a motor is installed behind the impeller, and a clean air outlet is provided behind the motor.

[0007] Preferably, a first telescopic rod is installed below the dust collection structure, the dust collection structure is covered by a cover plate, and a second telescopic rod is fixedly connected to the rear of the cover plate.

[0008] Preferably, the upper arm of the conveyor is fixedly mounted with a support frame, the support frame is fixedly mounted with a slide rod, four sliders are sleeved on the slide rod, the sliders are fixedly connected to two platforms on the same horizontal line, there are two connecting shafts between the platforms, the two connecting shafts are movably connected to the bearing shaft, the platform is vertically fixedly connected to the clamping plate, and an electric push rod is fixedly installed on one side of the clamping plate, and the electric push rod is placed on the strapping machine.

[0012] 1. This utility model reduces the occurrence of jamming by installing a dust-collecting structure. By installing the dust-collecting structure at a predetermined location, the user clicks the start button on the control panel. The cover is pulled into the hole by the first telescopic frame until it does not obstruct the dust-collecting structure from exiting. Then, the dust-collecting structure is pushed up by the second telescopic rod. After being pushed to the designated position, the impeller starts to rotate, sucking dust into the dust collection pipe, filtering it through the dust bag, and then expelling it from the clean air outlet. This reduces the occurrence of jamming and improves the service life.

[0013] 2. This utility model, by installing a support component, can prevent the carton from swaying when passing through the conveyor, thus avoiding crooked cable ties. When the carton reaches the support frame position via the conveyor, the clamping plates inside the support frame are pushed inward by an electric push rod. The bearing drives two connecting shafts through the shaft rotation, causing the two clamping plates to clamp the carton, restricting and adjusting the carton's position to prevent the carton from tilting and thus avoiding crooked cable ties. When the carton is tied with two cable ties, the lower circular plate will rotate through a large gear and a small gear. The small gear drives the shaft to move, causing the shaft frame to rotate and drive the carton to rotate 90 degrees, and then tie it again. Attached Figure Description

[0018] Please see Figure 1-6As shown, this is one technical optimization solution of the present invention: A strapping machine for cardboard box packaging includes a strapping machine 28 and a conveyor 1. The conveyor 1 is fixedly connected to one side of the strapping machine 28. A dust suction structure is provided inside the strapping machine 28, including a suction pipe 19, a dust filter bag 23, an impeller 24, a motor 25, and a clean air outlet 18. The dust filter bag 23 is movably connected to the rear of the suction pipe 19 of the outer casing 22. The dust filter bag 23 is movably connected to the outer casing 22. The impeller 24 is provided inside the outer casing 22, and the motor 25 is installed behind the impeller 24. The clean air outlet 18 is located behind the motor 25. A first telescopic rod 27 is installed below the dust suction structure. The dust suction structure is topped by a cover plate 12, and a second telescopic rod 13 is fixedly connected to the rear of the cover plate 12.

[0019] By installing a suction structure, the problem of dust jamming is reduced. By installing the suction device at a predetermined location, the user clicks the start button on the control panel 4. The cover 12 is pulled into the hole by the second telescopic rod 13 until it does not obstruct the suction structure from exiting. Then, the suction structure is pushed up by the second telescopic rod 13. After being pushed to the designated position, the impeller 24 starts to rotate, sucking dust into the suction pipe 19, filtering it through the dust bag 23, and then expelling it from the clean air outlet 18. This reduces the problem of dust jamming and improves the service life.

[0020] Furthermore, a support frame 26 is fixedly installed on the upper arm of the conveyor 1. A slide rod 10 is fixedly installed on the support frame 26. Four sliders 9 are fitted on the slide rod 10. The sliders 9 are fixedly connected to two platforms 7 on the same horizontal line. There are two connecting shafts 11 between the platforms 7. The two connecting shafts 11 are movably connected to the bearing shaft 8. The platform 7 is vertically fixedly connected to the clamping plate 29. An electric push rod 20 is fixedly installed on one side of the clamping plate 29 and is placed on the bundling machine 28. A U-shaped frame 6 is fixedly installed on the upper part of the bundling machine 28. A circular groove 30 is opened in front of the U-shaped frame 6. A large gear 14 and a small gear 15 are provided inside the circular groove 30. The small gear 15 is connected to a shaft 16. The circular groove 30 is sealed with a circular plate 3. A shaft frame 17 is installed at the lower part of the circular plate 3.

[0021] The installation of support frame 26 can prevent the carton from swaying when passing through conveyor 1, thus avoiding crooked cable ties. As the carton passes from conveyor 1 to support frame 26, the clamping plate 29 inside support frame 26 is pushed inward by electric push rod 20. The bearing shaft 8 drives two connecting shafts 11 through shaft rotation, so that the two clamping plates 29 clamp the carton, restricting the position of the carton and adjusting the position of the carton to prevent the carton from tilting and thus avoid crooked cable ties. When the carton is tied with two cable ties, the lower circular plate 3 will rotate through large gear 14 and small gear 15. Small gear 15 drives shaft 16 to move, causing shaft frame 17 to rotate and drive the carton to rotate 90 degrees, and then tie it again, reducing labor costs.

[0022] Furthermore, six sets of support columns 2 are fixedly installed below the strapping machine 28 and the conveyor 1, and wheels 5 are installed below the support columns 2. An operation panel 4 is fixedly installed on one side of the strapping machine 28.

[0023] The lower structure of the strapping machine 28 and the conveyor 1 is stably supported by six sets of evenly distributed support columns 2. These support columns 2 are securely connected and installed on the base of the equipment, forming the basic load-bearing frame of the equipment. To provide the necessary mobility, wheels 5 are installed at the bottom end of each support column 2. In addition, an integrated operation panel 4 is fixedly installed on the side of the main structure of the strapping machine 28, serving as a human-machine interface for operators to perform core operations such as parameter setting, status monitoring, and start / stop control.

[0024] Working principle: The support frame 26 is installed to prevent the carton from shaking when passing through the conveyor 1, so as to avoid the cable ties being tied crookedly. When the carton passes from the conveyor 1 to the support frame 26, the clamping plate 29 inside the support frame 26 is pushed inward by the electric push rod 20. The bearing shaft 8 drives the two connecting shafts 11 through the shaft rotation, so that the two clamping plates 29 clamp the carton, restrict the position of the carton and adjust the position of the carton, so as to prevent the carton from tilting and thus avoid the cable ties being tied crookedly. When the carton is tied with two cable ties, the lower circular plate 3 will rotate through the large gear 14 and the small gear 15. The small gear 15 drives the shaft 16 to move, so that the shaft frame 17 rotates and drives the carton to rotate 90 degrees, and then tie it again, reducing labor costs.

[0025] By incorporating a dust-collecting structure, jamming is reduced. The dust-collecting device is installed at a predetermined location. The user presses the start button on the control panel 4, and the cover 12 is pulled into the hole by the second telescopic rod 13 until it no longer obstructs the dust-collecting structure's exit. The dust-collecting structure is then pushed up by the second telescopic rod 13 to the designated position. The impeller 24 then rotates, drawing dust into the suction pipe 19, filtering it through the dust bag 23, and expelling it through the clean air outlet 18. This reduces jamming and extends the device's lifespan. The lower structure of the strapping machine 28 and conveyor 1 is stably supported by six evenly distributed support columns 2. These support columns 2 are securely connected and installed on the base of the equipment, forming the basic load-bearing frame. To provide necessary mobility, wheels 5 are installed at the bottom end of each support column 2. Furthermore, an integrated control panel 4 is fixedly installed on the side of the main structure of the strapping machine 28, serving as a human-machine interface for operators to perform core operations such as parameter setting, status monitoring, and start / stop control.
