Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to an adaptive carton sealing machine. Background Technology

[0002] Carton sealing machines, as automated packaging equipment, play a crucial role in production lines. Their primary function is to seal cartons filled with products, ensuring the safety and integrity of the products during transportation and storage. However, while existing carton sealing machine technology can efficiently seal cartons, its applicability is relatively limited when facing the diverse needs of different product lines.

[0003] Specifically, most existing carton sealing machines can only perform sealing and coding operations for one type or a specific type of product. This means that when the production line needs to handle products of different sizes, shapes, or brands, the carton sealing machine may need to frequently change parts or adjust settings to adapt to different carton specifications and coding requirements. This lack of flexibility not only reduces the efficiency of the production line but also increases operational complexity and maintenance costs. Utility Model Content

[0026] Please see Figure 1 An adaptive carton sealing machine includes a frame 1, a transmission module 2, and a sealing module 3. The frame 1 supports the transmission module 2 and the sealing module 3. The transmission module 2 is located at the top of the frame 1 and extends along the length of the frame 1. The sealing module 3 is located above the frame 1 and at one end of the length of the frame 1.

[0027] Please see Figure 1 and Figure 2 The frame 1 is a rectangular parallelepiped frame. Four supporting feet 11 are provided at the four corners of the bottom of the frame 1. In one embodiment, casters 12 are also provided at the bottom of the frame 1 to facilitate its movement. A carton tray 13 extends outward from the end of the frame 1 pointing towards the sealing module 3 to support the cartons.

[0028] The frame 1 is provided with two uprights 312 for supporting the sealing module 3. The two uprights 312 are vertically arranged. In one embodiment, the frame 1 is also provided with two laser detection modules 14, which are used to detect the width and height of the carton. In one embodiment, one laser detection module 14 is located inside the right-side upright of the frame 1 and is used to detect the height of the carton during operation. Protective covers 15 are provided at both ends of the frame 1 along the width direction near one end of the sealing module 3. The other laser detection module 14 is located on the protective cover 15 and is used to detect the width of the carton during operation. In one embodiment, a through-beam optical fiber 151 is also provided on the opposite side of the protective cover 15, located at one end along the length direction of the protective cover 15, and is used to detect the position of the carton entering the transmission module 2.

[0029] In one embodiment, the frame 1 is provided with an adjustment device for adjusting the air pressure, and the adjustment device is located below the front end of the frame 1.

[0030] Please see Figure 1 and Figure 2 In one embodiment, the transmission module 2 includes a power roller mechanism 21, which comprises rollers 211 arranged in an array along the length of the frame 1. The rotation of the rollers 211 drives the carton. Specifically, transmission gears 212 are provided at both ends of the rollers 211 along their length. Two conveyor motors 22 and a gear set 23 are provided inside the frame 1. The gear set 23 is provided with a transmission chain that meshes with the transmission gears 212 on the rollers 211. The conveyor motors 22 drive the rotation of the gear set 23, which in turn drives the rotation of the transmission gears 212, thereby driving the rotation of the rollers 211 to achieve the transmission of the carton. In one embodiment, a servo-driven positioning mechanism 24 is provided at the end of the transmission module 2 opposite to the sealing module 3 for positioning the carton. The servo positioning mechanism described in this application can be any known servo-driven positioning mechanism 24. In one embodiment, a brake device is provided below the power roller mechanism 21, and the brake device is located between two sets of parallel devices of the mechanism for clamping the carton in the front and rear widths.

[0031] In one embodiment, a blocking device 25 is provided in the middle of the power roller mechanism 21. The blocking device 25 includes a baffle plate 251, which is arranged perpendicular to the top surface of the frame 1. The baffle plate 251 is slidably arranged in the vertical direction and is located between two adjacent rollers 211. A driving device for driving the baffle plate 251 to slide in the vertical direction is provided in the frame 1. In one embodiment, the driving device is a driving cylinder 252.

[0032] In one embodiment, the transmission module further includes two conveyor belts 33, located on opposite sides of the frame 1 in the width direction and on opposite sides of the protective cover 15. The two conveyor belts 33 are slidably arranged along the width direction of the frame 1 and extend along the length direction of the frame 1. In use, the conveyor belts 33 slide in opposite directions, and when they abut against the carton, they drive the carton to slide towards the transmission module 2. (See also...) Figure 1 In one embodiment, the frame 1 is provided with a drive mechanism 34 for driving the conveyor belt 33 to slide. Please refer to [link to relevant documentation]. Figure 1 The drive mechanism 34 is provided in two sets, and the two sets of drive mechanisms 34 respectively drive the two conveyor belts 33 to move in the width direction.

[0033] In one embodiment, each set of drive mechanisms 34 includes a transmission mechanism 341 and a transverse cylinder 342. The transmission mechanism 341 is fixed below the conveyor belt 33 and includes a transmission block 3411 and a transmission guide rail 3412. The transmission block 3411 has a groove that matches the transmission guide rail 3412, allowing it to slide along the groove on the guide rail 3412. One end of the transverse cylinder 342 is rotatably mounted on the transmission block 3411, and the other end is rotatably fixed to the side wall of the frame 1 opposite to the transmission block 3411. The extension and retraction of the transverse cylinder 342 enables the sliding of the conveyor belt 33. In another embodiment, the two ends of the transverse cylinder 342 are connected by chains to form a closed-loop drive. During the sealing process, the carton moves inward and clamps the carton via the left and right conveyor belts 33, and then is driven by the conveyor belts 33.

[0034] The sealing module 3 is disposed at one end of the frame 1 along its length. The sealing module 3 includes an upper mechanism module 31 and a lower mechanism module 32. The upper mechanism module 31 is located above the frame 1 and slides vertically. In one embodiment, sliders 311 are provided at both ends of the upper mechanism module 31 in its width direction. A slide rail 3122 matching the sliders 311 is provided on the frame 1. The slide rail 3122 is perpendicular to the frame 1 and extends upwards. The upper mechanism module slides along the extension direction of the slide rail 3122. In one embodiment, a driving device for driving the sliders 311 to slide vertically is provided within the slide rail 3122. A touch screen 313 is provided on the upper mechanism module 31 for adjusting the entire sealing machine and displaying its status. In one embodiment, a laser detection device 3131 is provided on one side of the touch screen 313. The laser detection device 3131 is used to detect the position between the upper mechanism module 31 and the carton during operation.

[0035] The drive device can be any known electric drive device or pneumatic drive device. In this embodiment, the drive device includes both an electric drive device and a pneumatic drive device.

[0036] The distance between the upper mechanism module 31 and the carton is detected by a laser detection device 3131 during operation. When the distance is greater than 50mm, the upper mechanism module is driven electrically. When the distance is less than 50mm, the air path is switched, and the module slowly descends to press down on the carton. In one embodiment, a baffle 3121 is also provided on the outside of the slide rail 3122.

[0037] The lower core mechanism module 32 is located between the rollers 211 at the top of the frame 1. The lower core mechanism module 32 is correspondingly arranged with the upper core mechanism module 31. In one embodiment, the upper core mechanism module 31 and the lower core mechanism module 32 are respectively provided with an automatic sealing device 321. The automatic sealing device 321 is controlled by a touch screen 313. The automatic sealing device 321 uses tape to seal the upper and lower sides of the carton. The automatic sealing device 321 in this application is the same as the automatic sealing device 321 in the prior art. In one embodiment, the upper core mechanism module 31 and the lower core mechanism module 32 are respectively provided with a protective plate 322. The protective plate 322 is used to protect the tape on the automatic sealing device 321.

[0038] The frame 1 is also equipped with an inkjet printer 35, which is located at one end of the conveyor belt 33 along its length. The inkjet printer 35 is an automatic inkjet printer. Specifically, in one embodiment, the inkjet printer 35 is equipped with two printheads, namely printhead A and printhead B. In use, the position of the carton is monitored by a laser detection device 3131, and the signal is transmitted to the control panel in the touch screen 313. Then, the control panel controls the conveyor belt 33 to clamp the carton and drive the carton to move.

[0039] Working principle:

[0040] Workers open the cardboard boxes, place them on cardboard pallets, and then put the products inside the boxes;

[0041] After packing the products, close the carton and then push it into the self-adaptive carton sealing machine;

[0042] The cardboard box is detected by the through-beam fiber optic cable 151. The upper mechanism module 31 descends. During descent, the laser detection device 3131 of the upper mechanism module 31 detects that when the upper mechanism module 31 is approximately 50mm away from the cardboard box, it switches the air path, slowly descending to press down on the cardboard box. Simultaneously, the conveyor belts 33 on both sides close. Once closed, the positioning cylinder on the lower left of the roller 211 activates the drive shaft below the conveyor belts 33 on both sides to prevent excessive clamping. At the same time, the cardboard box is conveyed, and the upper and lower sealing devices seal the box during the conveying process.

[0043] The width of the carton is detected by the laser detection module 14 on the right, and the height of the carton is detected by the laser detection module 14 inside the right column, identifying whether the carton is product A or B. Then, the inkjet printer 35 at the end of the conveyor belt 33 prints the corresponding carton with printhead A or B, and the printing is also completed during the carton conveying process.

[0044] After the inkjet printing is completed, the power roller mechanism 21 transports the carton to the front barrier plate 251. When there is no carton at the front, the barrier plate 251 descends, and the carton flows to the front end. Then the barrier plate 251 rises again. At the same time, the servo-driven positioning mechanism 24 moves and positions the carton, and the robot picks up the carton.

[0045] The adaptive carton sealing machine provided in this application uses a laser detection module 14 to detect the height and width of the product, enabling accurate identification of product A or B type cartons during sealing. This allows the control panel to control the inkjet printer 35, enabling inkjet printing on the corresponding cartons and achieving inkjet printing for different products. The adaptive carton sealing machine provided in this application can handle different products and has the advantages of high adaptability and simple operation.
