Description

Technical Field

[0001] This utility model relates to the field of strapping machine structure technology, specifically a strapping machine strapping force adaptive adjustment structure. Background Technology

[0002] At the end of the production line in industries such as food, electronics, and daily necessities, a large number of products with packaging boxes need to be bundled together into a stack. Strapping machines can quickly use strapping to tightly bind the packaging boxes, which facilitates subsequent warehousing and transportation. Compared with manual strapping, strapping machines are more efficient and can significantly reduce the intensity of manual labor.

[0003] Current strapping machines often have difficulty adjusting the strapping force, and the power source outputs a relatively fixed amount of strapping tape each time. Considering that different packaging materials have significantly different requirements for strapping force, excessive strapping force may cause the packaging box to be crushed, the corners to be deformed, or even the contents to be damaged. On the other hand, insufficient strapping force may cause the strapping to loosen and easily come apart during transportation, increasing the risk of breakage. Based on this, we propose a new type of strapping machine with adaptive strapping force adjustment structure. Utility Model Content

[0004] The purpose of this utility model is to provide a strapping machine strapping force adaptive adjustment structure to solve the problems of difficult strapping force adjustment and poor adaptive effect mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a strapping machine strapping force adaptive adjustment structure, including a fixed frame, a PLC controller installed on the outer wall of the fixed frame, a horizontal longitudinal slide rail fixed at the bottom of the fixed frame, a horizontal transverse slide rail fixed at the bottom of the horizontal longitudinal slide rail, a motor, a lead screw, and a nut seat sequentially installed on both the horizontal transverse slide rail and the horizontal longitudinal slide rail, a first horizontal transverse positioning arm and a second horizontal transverse positioning arm slidably connected to both ends of the horizontal transverse slide rail, a first horizontal longitudinal positioning arm and a second horizontal longitudinal positioning arm slidably connected to both sides of the horizontal longitudinal slide rail, a horizontal laser displacement sensor installed at the top of both the first horizontal transverse positioning arm and the first horizontal longitudinal positioning arm, a strapping platform provided at the top of the horizontal transverse slide rail, a vertical laser displacement sensor installed at the top of the fixed frame, and a CCD camera installed on one side of the fixed frame.

[0006] As a further technical solution of this utility model, the bottom of the fixing frame is uniformly provided with screw holes, and the outer side wall of the fixing frame is vulcanized with an anti-slip rubber layer.

[0007] As a further technical solution of this utility model, a partition block is fixed at the middle position of the lead screw, and an external thread layer with opposite directions is provided on the outer side wall of the lead screw.

[0008] As a further technical solution of this utility model, the inner sidewall of the nut seat is provided with an internal thread layer that matches the external thread layer, and the adjacent nut seats are symmetrically distributed about the vertical center line of the separator block.

[0009] As a further technical solution of this utility model, the output end of the motor is connected to a worm gear, and a worm wheel is provided between the worm gear and the lead screw.

[0010] As a further technical solution of this utility model, bearings are provided between the worm gear and the worm and the horizontal longitudinal slide rail and the horizontal transverse slide rail, respectively.

[0011] As a further technical solution of this utility model, the bottoms of the first horizontal transverse positioning arm, the second horizontal transverse positioning arm, the first horizontal longitudinal positioning arm, and the second horizontal longitudinal positioning arm are respectively fixed on the nut seat.

[0012] As a further technical solution of this utility model, the first horizontal lateral positioning arm, the first horizontal longitudinal positioning arm, the horizontal laser displacement sensor, the fixing frame, the vertical laser displacement sensor, the CCD camera, and the fixing frame are all connected by screws to form a disassembly and installation structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are: By incorporating a first horizontal longitudinal positioning arm, the device optimizes its structure. Horizontal laser displacement sensors, corresponding to the second horizontal and longitudinal positioning arms, are respectively installed on the top of the first horizontal and longitudinal positioning arms. This allows for real-time monitoring of the distances between the first and second horizontal and longitudinal positioning arms. When these four arms are in contact with the outer wall of the product, this distance represents the length and width of the packaging box. Furthermore, in the initial state, the vertical laser displacement sensor monitors its distance from the strapping platform using laser ranging. When a product is placed on the platform, the vertical laser displacement sensor monitors its distance from the top surface of the product. The height of the packaged product can be calculated by changing the distance, which enables the device to achieve fully automated detection of the packaging box binding size. Furthermore, when the CCD camera is activated, it can identify different materials on the surface of the packaging, such as printed paper boxes and transparent plastic boxes, based on image recognition algorithms, and feed this information back to the PLC controller. This allows the PLC controller to call up the preset material force parameter library. For example, plastic boxes can withstand greater force than paper boxes. Through automated monitoring and feedback of product binding size and product material, the output strength of the strapping machine's power source can be adaptively adjusted, achieving adaptive adjustment of binding force. This avoids excessive fixing force that could crush the packaging box and deform the corners, or insufficient fixing force that could cause the binding to loosen, thus optimizing the binding effect. By installing horizontal transverse slide rails, the device optimizes its performance. The user or robotic arm places the packaging box onto the strapping platform, then activates the motors on the horizontal transverse and vertical slide rails. This, combined with a two-stage transmission structure consisting of a worm gear, worm wheel, lead screw, and nut seat, and with oppositely oriented external threads on the outer wall of the lead screw, drives the first and second horizontal transverse positioning arms symmetrically distributed on the horizontal transverse slide rail, and the first and second horizontal longitudinal positioning arms symmetrically distributed on the horizontal longitudinal slide rail, to move synchronously closer to each other. This allows the first, second, and third horizontal transverse positioning arms to automatically calibrate and position the packaging box in four directions (front, back, left, and right), ensuring it is centered in the strapping position. This improves the relative positional accuracy of the strapping rope and the strapped product. Furthermore, the self-locking effect of the worm wheel and worm gear ensures that the first, second, and third horizontal transverse positioning arms, after being adjusted to their correct positions, are less prone to shifting.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figure 1-5 An embodiment of this utility model provides: a strapping machine strapping force adaptive adjustment structure, including a fixed frame 3, a PLC controller 6 installed on the outer side wall of the fixed frame 3, a horizontal longitudinal slide rail 9 fixed at the bottom inside the fixed frame 3, a horizontal transverse slide rail 13 fixed at the bottom of the horizontal longitudinal slide rail 9, and a motor 18, a lead screw 11 and a nut seat 12 sequentially installed on both the horizontal transverse slide rail 13 and the horizontal longitudinal slide rail 9. The two ends of the horizontal transverse slide rail 13 are respectively slidably connected to the first horizontal transverse positioning arm 2 and the second horizontal transverse positioning arm 5, and the two sides of the horizontal longitudinal slide rail 9 are respectively slidably connected to the first horizontal longitudinal positioning arm 7 and the second horizontal longitudinal positioning arm 8. A partition block 10 is fixed at the middle position of the lead screw 11, and an external thread layer with opposite directions is provided on the outer side wall of the lead screw 11. The inner wall of the nut seat 12 is provided with an internal thread layer that matches the external thread layer, and adjacent nut seats 12 are symmetrically distributed about the vertical center line of the separator block 10. The output end of the motor 18 is connected to a worm gear 16, and a worm wheel 17 is provided between the worm gear 16 and the lead screw 11. Bearings are provided between the worm gear 17 and the worm 16 and the horizontal longitudinal slide rail 9 and the horizontal transverse slide rail 13, respectively. The bottoms of the first horizontal transverse positioning arm 2, the second horizontal transverse positioning arm 5, the first horizontal longitudinal positioning arm 7, and the second horizontal longitudinal positioning arm 8 are respectively fixed on the nut seat 12. The top of the first horizontal transverse positioning arm 2 and the first horizontal longitudinal positioning arm 7 are both equipped with a horizontal laser displacement sensor 1, and the top of the horizontal transverse slide rail 13 is provided with a binding platform 4. Specifically, such as Figure 2 , Figure 3 and Figure 5As shown, the user or robotic arm delivers the packaging box to the strapping platform 4, then activates the motor 18 on the horizontal transverse slide rail 13 and the horizontal longitudinal slide rail 9. This, along with the two-stage transmission structure consisting of the worm gear 16 and worm wheel 17, and the lead screw 11 and nut seat 12, and based on the opposite-direction external thread layers on the outer wall of the lead screw 11, can drive the first horizontal transverse positioning arm 2 and the second horizontal transverse positioning arm 5 symmetrically distributed on the horizontal transverse slide rail 13, and the first horizontal longitudinal positioning arm 7 and the second horizontal longitudinal positioning arm 8 symmetrically distributed on the horizontal longitudinal slide rail 9, to perform synchronous operation. The movement of the arms, which move closer to each other, allows for automated calibration and positioning of the packaging box product in four directions (front, back, left, and right) through the first horizontal lateral positioning arm 2, the second horizontal lateral positioning arm 5, the first horizontal longitudinal positioning arm 7, and the second horizontal longitudinal positioning arm 8. This ensures that the product is in the center of the binding position, improving the relative positional accuracy of the binding rope and the binding product. Furthermore, the self-locking effect of the worm gear 17 and the worm 16 also ensures that the first horizontal lateral positioning arm 2, the second horizontal lateral positioning arm 5, the first horizontal longitudinal positioning arm 7, and the second horizontal longitudinal positioning arm 8 are not prone to deviation after being adjusted to their intended use positions. A vertical laser displacement sensor 14 is installed at the top inside the fixture 3, and a CCD camera 15 is installed on one side inside the fixture 3. The bottom of the fixing frame 3 is evenly provided with screw holes, and the outer side wall of the fixing frame 3 is vulcanized with an anti-slip rubber layer. The first horizontal lateral positioning arm 2, the first horizontal longitudinal positioning arm 7, the horizontal laser displacement sensor 1, the fixing frame 3, the vertical laser displacement sensor 14, and the CCD camera 15 and the fixing frame 3 are all connected by screws to form a disassembly and installation structure. Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, by installing horizontal laser displacement sensors 1 corresponding to the second horizontal positioning arm 5 and the second horizontal positioning arm 8 on the top of the first horizontal lateral positioning arm 2 and the first horizontal longitudinal positioning arm 7 respectively, the distances between the first horizontal lateral positioning arm 2 and the second horizontal lateral positioning arm 5, and between the first horizontal longitudinal positioning arm 7 and the second horizontal longitudinal positioning arm 8 can be monitored in real time. When the four are in contact with the outer wall of the product, this distance is the length and width of the packaging box product. In the initial state, the vertical laser displacement sensor 14 monitors its distance from the strapping platform 4 through laser ranging. When a product is placed, the vertical laser displacement sensor 14 will monitor its distance from the upper surface of the product. The change in distance can be used to measure the distance between the product and the product. The device calculates the height of the packaged product, enabling fully automated detection of the packaging box's bundling dimensions. Furthermore, the CCD camera 15, activated using image recognition algorithms, identifies different materials on the packaging surface, such as printed cardboard boxes and transparent plastic boxes, and feeds this information back to the PLC controller 6. The PLC controller 6 then calls upon a preset material strength parameter library; for example, plastic boxes can withstand higher forces than cardboard boxes. This automated monitoring and feedback of product bundling dimensions and material allows for adaptive adjustment of the output strength of the strapping machine's power source, preventing excessive force that could crush the packaging box or deform its edges, or insufficient force that could cause loose bundling, thus optimizing the bundling effect.

[0018] Working principle: In use, an external power supply is connected. First, the user or robotic arm places the packaging box onto the strapping platform 4. Then, the motors 18 on the horizontal transverse slide rail 13 and the horizontal longitudinal slide rail 9 are started. This, along with the two-stage transmission structure consisting of the worm gear 16 and worm wheel 17, and the lead screw 11 and nut seat 12, and based on the opposite-direction external thread layers on the outer wall of the lead screw 11, drives the first horizontal transverse positioning arm 2 and the second horizontal transverse positioning arm 5 symmetrically distributed on the horizontal transverse slide rail 13, and the first horizontal longitudinal positioning arm 7 and the second horizontal longitudinal positioning arm 8 symmetrically distributed on the horizontal longitudinal slide rail 9, to move synchronously closer to each other, thereby passing through the first water... The horizontal positioning arm 2, the second horizontal positioning arm 5, the first horizontal longitudinal positioning arm 7, and the second horizontal longitudinal positioning arm 8 automatically calibrate and position the packaging box product in four directions (front, back, left, and right) to ensure it is in the centered binding position, improving the relative positional accuracy of the binding rope and the bound product. Furthermore, the self-locking effect of the worm gear 17 and worm 16 ensures that the first horizontal positioning arm 2, the second horizontal positioning arm 5, the first horizontal longitudinal positioning arm 7, and the second horizontal longitudinal positioning arm 8 are not prone to displacement after being adjusted to their correct positions. In addition, by installing corresponding positioning arms on the top of the first horizontal positioning arm 2 and the first horizontal longitudinal positioning arm 7, the second horizontal positioning arm 8... The horizontal laser displacement sensor 1, corresponding to arm 5 and the second horizontal longitudinal positioning arm 8, can monitor the distances in real time between the first horizontal lateral positioning arm 2 and the second horizontal lateral positioning arm 5, as well as the first horizontal longitudinal positioning arm 7 and the second horizontal longitudinal positioning arm 8. When the four arms are in contact with the outer wall of the product, this distance is the length and width of the packaging box. Furthermore, in the initial state, the vertical laser displacement sensor 14 monitors its distance from the strapping platform 4 through laser ranging. When a product is placed on the platform, the vertical laser displacement sensor 14 monitors its distance from the top surface of the product. By measuring the change in distance, the height of the packaging box can be calculated. This allows the device to achieve [the following functions / measurements]. The system features fully automated detection of packaging box bundling dimensions. Furthermore, the CCD camera 15, once activated, can identify different materials on the packaging surface, such as printed cardboard boxes and transparent plastic boxes, based on image recognition algorithms. This information is then fed back to the PLC controller 6, allowing the PLC controller 6 to access a pre-set library of material strength parameters. For example, plastic boxes can withstand higher forces than cardboard boxes. Through automated monitoring and feedback of product bundling dimensions and material, the power source of the bundling machine can adaptively adjust its output strength. This achieves adaptive adjustment of bundling force, preventing excessive fixing force from crushing the packaging box and deforming its corners, or insufficient fixing force from causing the bundling to loosen, thus optimizing the bundling effect.
