Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging technology, and in particular to an adjustable packaging device. Background Technology
[0002] Adjustable packing devices are automated equipment used to seal, bundle, and label packaging boxes. They are widely used in logistics, e-commerce, and manufacturing industries. The core objective of adjustable packing devices is to improve packing efficiency, reduce costs, and ensure packaging quality through automation.
[0003] Existing adjustable packing devices typically include a conveyor assembly and a strapping assembly. The conveyor assembly usually uses a conveyor belt to transport the packaging bag containing the items directly below the strapping assembly. At this point, the strapping assembly starts to rotate the stored plastic tape along with the wrapping arm, evenly wrapping the plastic tape around the outer surface of the packaging bag. Because the plastic tape is relatively light, it may deform when wrapped.
[0004] In the use of existing adjustable packaging devices, plastic tape is usually wound at one end of the wrapping arm, with the end of the plastic tape extending from the other end of the wrapping arm. When the plastic tape is wound at high speed, the plastic tape may wrinkle and deform when it comes into contact with the surface of the packaging bag, thus affecting the quality of the bundling and packaging. Utility Model Content
[0005] To address the issue that the high-speed rotation of the wrapping arm in existing adjustable packaging devices can cause the plastic tape to wrinkle and deform when it comes into contact with the packaging bag surface, thus affecting the quality of the bundling and packaging.
[0006] The technical solution of this utility model is as follows: an adjustable packaging device, including a frame, a conveyor belt rotatably connected to the middle of the frame, a gantry frame fixed at the top of the frame, a cylinder fixed at the top of the gantry frame, a mounting base movably connected to the inner top of the gantry frame, a first motor fixed at the inner bottom of the mounting base, a winding arm fixed at the output end of the first motor, a first slot opened on the side wall of the winding arm, a take-up roller rotatably connected inside the first slot, two support frames fixed on the side wall of the winding arm near the first slot, a first limiting roller rotatably connected to the inner side wall of each support frame, a second limiting roller rotatably connected to the inner side wall of each support frame near the first limiting roller, a second motor fixed at the top of the support frame, a second slot opened on the side wall of each support frame near both ends of the second limiting roller, a locking block movably connected to the middle of each second slot, and a spring fixed on the side wall of each locking block.
[0007] Preferably, the outer surface of the take-up roller is wrapped with plastic tape, which passes between the first limiting roller and the second limiting roller. The first limiting roller and the second limiting roller have the same external dimensions. The outer surface of the second limiting roller is coated with an anti-sticking agent, and the outer surface of the first limiting roller is fitted with an anti-slip pad, which improves the stability of the movement of the plastic tape.
[0008] Preferably, the external dimensions of the clamping blocks are adapted to the internal dimensions of the second slot, the clamping blocks are rotatably connected to both ends of the second limiting roller, the other end of the spring is fixed on the inner side wall of the second slot, and a damper is provided in the middle of each spring to improve the stability of the clamping performance of the second limiting roller.
[0009] Preferably, the output end of the cylinder passes through the gantry frame and is fixed in the middle of the top of the mounting base, which is U-shaped.
[0010] Preferably, both the winding arm and the support frame are L-shaped, and the support frame is symmetrically distributed and fixedly connected to the winding arm to form an integrated structure.

The elastic force of the two springs acts on the side wall of the clamping block, thereby improving the adaptability of the second limiting roller in holding the plastic tape. This allows the plastic tape to be evenly wrapped around the outer surface of the packaging bag along the surface of the second limiting roller, thus improving the quality of plastic tape bundling and packaging.

Detailed Implementation
[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please see Figures 1-4 An adjustable packaging device includes a frame 1, with a conveyor belt 2 rotatably connected to the middle of the frame 1. A motor is installed on the side wall of the frame 1 to cooperate with a roller shaft rotatably connected to the inner side wall of the frame 1, thereby driving the conveyor belt 2 to rotate. Placing loaded packaging bags on the surface of the conveyor belt 2 enables linear transport of goods. A gantry frame 3 is welded to the top of the frame 1, and a cylinder 4 is bolted to the top of the gantry frame 3. A mounting base 5 is movably connected to the inner top of the gantry frame 3. The output end of the cylinder 4 passes through the gantry frame 3 and is fixed to the middle of the top of the mounting base 5 via a coupling. Activating the cylinder 4 can drive the mounting base 5 to move vertically, thereby facilitating the adjustment of the height of the mounting base 5. The mounting base 5 is U-shaped, and a first motor 6 is bolted to the inner bottom of the mounting base 5. A winding arm 7 is fixed to the output end of the first motor 6 via a coupling. A first slot 8 is opened on the side wall of the winding arm 7, and the interior of the first slot 8 rotates... A take-up roller 9 is movably connected, and plastic tape is wound around the outer surface of the take-up roller 9. Two support frames 10 are fixed on the side wall of the winding arm 7 near the first slot 8. A first limiting roller 11 is rotatably connected to the inner side wall of each support frame 10. A second limiting roller 12 is rotatably connected to the inner side wall of the support frame 10 near the first limiting roller 11. The first limiting roller 11 and the second limiting roller 12 are used for support and limiting, respectively. A second motor 14 is fixed at the top of the support frame 10. The output end of the second motor 14 is fixed at the top of the first limiting roller 11. Starting the second motor 14 can drive the first limiting roller 11, thereby improving the output efficiency of the plastic tape. A second slot 16 is opened on the side wall of the support frame 10 near both ends of the second limiting roller 12. A locking block 17 is movably connected in the middle of the second slot 16. The locking block 17 is rotatably connected to both ends of the second limiting roller 12. A spring 18 is fixed on the side wall of the locking block 17.
[0021] Please see Figures 1-4The plastic tape passes between the first limiting roller 11 and the second limiting roller 12. The first limiting roller 11 and the second limiting roller 12 have the same external dimensions. The outer surface of the second limiting roller 12 is sprayed with an anti-sticking agent to prevent the plastic tape from sticking. The outer surface of the first limiting roller 11 is covered with an anti-slip pad to increase friction resistance and improve the stability of the first limiting roller 11 in supporting and limiting the movement of the plastic tape. The external dimensions of the locking block 17 are adapted to the internal dimensions of the second slot 16. The other end of the spring 18 is fixed on the inner side wall of the second slot 16. A damper is provided in the middle of each spring 18 to improve the stability of the second limiting roller 12 in clamping.
[0022] Please see Figures 3-4 Both the winding arm 7 and the support frame 10 are L-shaped. The support frame 10 is symmetrically distributed and fixedly connected to the winding arm 7 to form an integrated structure, which improves the stability of the support. The blade 13 is rotatably connected to the side wall of the support frame 10 near the first limiting roller 11. The third motor 15 is fixed to the side wall of the support frame 10 by bolts. The output end of the third motor 15 is fixed to the top of the blade 13 by a coupling. The third motor 15 is fixed to the side wall near the first limiting roller 11 with saw teeth 19. Starting the third motor 15 can drive the blade 13 to rotate, thereby cutting the tightly bound plastic tape with saw teeth 19, which improves the convenience of cutting.
[0023] During operation, the operator first moves the device to the designated position, fixes the winding arm 7 to the output end of the first motor 6 via a coupling, and then rotatably connects the take-up roller 9, which is wrapped with plastic tape, to the inner wall of the first slot 8. One end of the plastic tape is passed through the gap between the first limiting roller 11 and the second limiting roller 12, so that the adhesive side of the plastic tape adheres to the outer surface of the second limiting roller 12, and the other side of the plastic tape adheres to the outer surface of the first limiting roller 11. The packaged bag containing the goods is placed on the surface of the conveyor belt 2, and the conveyor belt 2 is started to drive the packaged bag to be transported linearly. When the packaged bag moves directly under the winding arm 7, the conveyor belt 2 stops driving. At this time, the cylinder 4 is activated to drive the mounting base 5 to move vertically downward. The height of the wrapping arm 7 is adjusted to accommodate different packaging bags. The first motor 6 is started to drive the wrapping arm 7 to rotate counterclockwise, thereby extending the plastic tape under the action of centrifugal force. The plastic tape follows the rotation of the wrapping arm 7 and wraps around the outer surface of the packaging bag, thus achieving bundling. The second motor 14 is started to drive the first limiting roller 11 to rotate counterclockwise, thereby improving the efficiency of the plastic tape extension. The elastic force of the spring 18 acts on the side wall of the clamping block 17, pushing the second limiting roller 12 to clamp the plastic tape, improving the stability of the cooperation between the first limiting roller 11 and the second limiting roller 12, so that the plastic tape is evenly wrapped around the outer surface of the packaging bag along the surface of the second limiting roller 12, thereby improving the quality of plastic tape bundling and packaging.
[0024] Through the above steps, by setting a support frame 10, a first limiting roller 11, a second limiting roller 12, a second slot 16, a clamping block 17, and a spring 18 on the side wall of the winding arm 7 according to requirements, the plastic tape is supported and limited by the first limiting roller 11 and the second limiting roller 12, so that the plastic tape is output smoothly along the surface of the second limiting roller 12. The second motor 14 is started to drive the first limiting roller 11 to rotate counterclockwise, which improves the efficiency of plastic tape output from the surface of the winding roller 9. The elastic force of the spring 18 acts on the side wall of the clamping block 17 to improve the adaptability of the second limiting roller 12 in clamping the plastic tape, thereby improving the quality of plastic tape bundling and packaging.
