Description

Technical Field

[0001] This utility model relates to the field of tape packaging devices, and in particular to a wrapping tape packaging device. Background Technology

[0002] Currently, online shopping has become one of the mainstream shopping methods. With the increasing demand for online shopping, the volume of logistics has also increased, leading to an explosive growth in the processing volume of express parcels. Express parcels are often packaged using cardboard boxes, foam boxes, and plastic boxes. Among these, cardboard boxes have become the preferred choice for logistics packaging due to their advantages such as light weight, high strength, good cushioning effect, and high economic and environmental friendliness.

[0003] When packing goods, cardboard is first folded and connected to form an open-top box. The goods and fillers are then placed inside. The two side flaps on the top of the box are folded in half to close the opening. Finally, tape is used to bond the two side flaps together along their intersection. Because the tape uses its width to bond the flaps, the contact area between each flap and the tape is less than half the width of the tape, resulting in relatively low connection strength. The flaps may still separate during loading and unloading due to impacts, necessitating further repairs. The tape is wrapped along the direction of the intersection line of the two wing plates perpendicular to each other. However, wrapping the tape requires turning the box over and tightening the tape to stick it to the surface of the box. Without the skills and experience, especially for new employees, the operation is difficult and the packaging efficiency is low, which prevents the daily processing capacity from being increased. The existing tape sealing device can only connect the two wing plates together along the intersection line of the two wing plates, but cannot wrap the box along the direction perpendicular to the intersection line of the two wing plates. Manual wrapping is still required, which is difficult and inefficient. Utility Model Content

[0007] In the above-mentioned wrapping tape packaging device, the support includes a side plate and two end blocks. The side plate is connected to the end face of the rotating ring. The two end blocks are spaced apart on the side of the side plate adjacent to the card seat. The pressure roller is disposed between the two end blocks. The two sliding grooves correspond one-to-one with the two end blocks and are opened on the corresponding end blocks. The traction roller shaft is disposed on one side of the two end blocks and rotates with the two end blocks.

[0008] In the above-mentioned wrapping tape packaging device, the handle includes a pull handle that passes through the side plate and a connecting frame disposed between the side plate and the pressure roller.

[0015] The beneficial effects of this utility model after adopting the above technical solution are as follows:

[0016] This solution involves installing mounting rollers on a vertical plate, onto which tape rolls are mounted. The bracket on the rotating ring is initially positioned, horizontally adjacent to the mounting roller. In use, the carton is inserted into the mounting bracket. The pressure roller on the bracket, under the pressure of a spring, presses against the surface of the carton, pulling the tape roll down to the height of the rotating ring's axis. Then, the handle is pulled outwards from the rotating ring, separating the pressure roller from the carton's surface and moving the pulled-down tape between the pressure roller and the carton. Releasing the handle causes the pressure roller to quickly press the tape firmly against the carton's surface. With the activation of the drive assembly, the rotating ring rotates, causing the pressure roller and traction roller on the bracket to rotate around the ring's axis. The carton is fixed to the rotating ring's axis by the mounting bracket. During the rotation of the pressure roller and traction roller, the traction roller continuously pushes the tape, causing the tape roll to continuously release tape, thus continuously obtaining... The tape is picked up and, after passing the traction roller, is pressed against the surface of the carton by the pressure roller. As the rotating ring rotates, the pressure roller rolls synchronously around the carton, pressing the tape onto it. During the pushing of the tape by the traction roller, the path between the tape and the rotating ring changes accordingly. When the tape touches the cutter, it is split in two. The portion of the tape connected to the tape roll falls back down below the mounting roller, while the portion connected to the carton tilts towards the mounting roller in an arc shape above the traction roller due to the tilt angle and the push of the cutter. As the traction roller and pressure roller circle the carton once, the tape is wrapped around it, completing one work cycle. When the carton needs to be wrapped again, the next work cycle begins. This tape-wrapping device packs cartons by wrapping the tape, thereby reducing packaging difficulty and improving packaging efficiency, increasing daily processing capacity, and thus increasing production capacity.

[0026] The technical solution of this utility model will be further described in detail below with reference to specific embodiments, but this does not constitute any limitation on this utility model.

[0027] Example 1:

[0028] like Figure 1-5 As shown, the wrapping tape device includes a vertical plate 1. The vertical plate 1 has a mounting roller 11 for inserting the inner ring of the tape roll 2. Below the mounting roller 11, there is a rotating ring 6 and a drive assembly 5 for driving the rotating ring 6 to rotate unidirectionally. The power output end of the drive assembly 5 is connected to the rotating ring. The rotating ring 6 rotatably engages with the vertical plate 1. The inner ring of the rotating ring 6 has a cardboard holder 7 for securing the cardboard box. The cardboard holder 7 is fixed to the vertical plate 1. The rotating ring 6 has a bracket located on one side of the cardboard holder 7. The bracket has a pressure roller 82 for pressing the tape to adhere to the cardboard box. The pressure roller 82 is supported by a spring 85, a traction roller shaft 81 for pulling the conveyor belt, and a handle that passes through the pressure roller 82. The traction roller shaft 81 is located on one side of the support in the direction of rotation. The spring 85 is fixed on the support. The pressure roller 82 is located between the spring 85 and the retainer 7. The pressure roller 82 is rotatably engaged with the support and slidably engaged with the support along the radial direction of the rotating ring 6. The handle is slidably engaged with the support and rotatably engaged with the pressure roller 82. A cutter 3 for cutting the conveyor belt is provided above the rotating ring 6. The cutter 3 is located on the vertical plate 1 and its height is lower than that of the traction roller shaft 81.

[0029] The specific working principle is as follows: An mounting roller 11 is installed on the vertical plate 1, and the tape roll 2 is fitted onto the mounting roller 11. The bracket on the rotating ring 6 is in its initial position, located on the horizontal side adjacent to the mounting roller 11. During use, the carton is inserted into the cardboard holder 7. Under the pressure of the compression spring 85, the pressure roller 82 on the bracket abuts against the surface of the carton, pulling the tape on the tape roll 2 down to the height of the rotating ring 6's axis. Then, the handle is pulled outwards from the rotating ring 6, causing the pressure roller 82 to contact the carton. The surface of the tape separates, and the pulled tape is moved between the pressure roller 82 and the carton. After the handle is released, the pressure roller 82 quickly presses the tape against the surface of the carton. As the drive assembly 5 is activated, the drive assembly 5 drives the rotating ring 6 to rotate, and drives the pressure roller 82 and the traction roller shaft 81 on the bracket to make a circular motion around the axis of the rotating ring 6. The carton is fixed at the axis of the rotating ring 6 by the card holder 7. During the circular motion of the pressure roller 82 and the traction roller shaft 81, the traction roller shaft 81 continuously pushes the tape, causing the tape roll 2 to... Tape is continuously released, thus continuously acquiring tape. After passing the traction roller 81, the tape is pressed against the surface of the carton by the pressure roller 82. As the rotating ring 6 rotates, the pressure roller 82 rolls synchronously around the carton surface, pressing the tape onto the carton. During the pushing of the tape by the traction roller 81, the path between the tape and the rotating ring 6 also changes. When the tape touches the cutter 3, the tape is split in two. The portion of the tape connected to the tape roll 2 falls back down below the mounting roller 11, while the portion connected to the paper... The tape connecting the carton is tilted towards the mounting roller 11 in an arc shape as the cutting blade 3 pushes it. As the traction roller 81 and pressure roller 82 surround the carton, the tape is wrapped around the carton, completing one work cycle. When the carton needs to be wrapped again, the next work cycle begins. This allows the tape sealing device to pack the carton by wrapping the tape, thereby reducing the packing difficulty and improving the packing efficiency, increasing the daily processing capacity, and thus increasing production capacity.

[0030] In some embodiments, the mounting roller 11 is rotatably engaged with the vertical plate 1, while the tape roll 2 is fixed relative to the mounting roller 11. In this case, the inner diameter of the tape roll 2 matches the outer diameter of the mounting roller 11. In other embodiments, the mounting roller 11 is fixed on the vertical plate 1, while the tape roll 2 is rotatably engaged with the mounting roller 11. In this case, the inner diameter of the tape roll 2 is larger than the outer diameter of the mounting roller 11.

[0031] like Figure 3As shown, the specific connection structure between the pressure roller 82 and the bracket is as follows: two sliding grooves extending radially along the rotating ring 6 are provided on the bracket; sliders 84 are provided on both ends of the pressure roller 82; the sliders 84 are rotatably engaged with the ends of the corresponding pressure roller 82; the two sliders 84 correspond one-to-one with the two sliding grooves and are slidably engaged; two pressure springs 85 are provided, and they correspond one-to-one with the two sliding grooves; the pressure springs 85 are correspondingly located in the sliding grooves; one end of the pressure spring 85 is connected to the side wall of the corresponding sliding groove, and the other end is connected to the slider 84 adjacent to the pressure spring 85.

[0032] In the specific configuration, the slider 84 is preferably a square. In addition to squares, it can also be a rectangular block or other polygonal prism structure. This embodiment does not impose too many restrictions on this.

[0033] like Figure 3 As shown, the specific structure of the bracket is as follows: the bracket includes a side plate 8 and two end blocks 83. The side plate 8 is connected to the end face of the rotating ring 6. The two end blocks 83 are spaced apart on one side of the side plate 8 adjacent to the card seat 7. The pressure roller 82 is located between the two end blocks 83. Two sliding grooves correspond one-to-one with the two end blocks 83. The sliding grooves are opened on the corresponding end blocks 83. The traction roller shaft 81 is located on one side of the two end blocks 83 and rotates with the two end blocks 83.

[0034] In the specific configuration, the rotating ring 6 rotates clockwise, and correspondingly, the traction roller shaft 81 is located on one side of the clockwise rotation direction of the support, that is, on the side of the rotational forward direction of the support.

[0035] Combination Figure 4 and Figure 5 As shown, the specific structure of the handle is as follows: the handle includes a pull handle 87 that passes through the side plate 8 and a connecting frame 89 located between the side plate 8 and the pressure roller 82. The connecting frame 89 is connected to the pull handle 87 and rotates with both ends of the pressure roller 82.

[0036] Combination Figure 1 and Figure 3 As shown, the specific structure of the card holder 7 is as follows: the card holder 7 has a cavity for engaging with the carton; an L-shaped rod 86 is provided on the side of the bracket away from the rotating ring 6; one end of the L-shaped rod 86 slides along the axial direction of the rotating ring 6 and engages with the bracket; the other end of the L-shaped rod 86 faces the cavity; the bracket is also provided with a tightening bolt 88; the tightening bolt 88 is threadedly connected to the bracket in an adjustable manner and abuts against the L-shaped rod 86.

[0037] In this embodiment, an L-shaped rod 86 is provided. The L-shaped rod 86 extends and retracts on the bracket, abutting against the side of the carton facing away from the cardboard holder 7. Then, the tightening bolt 88 is tightened, pressing the L-shaped rod 86 firmly against the bracket, thus fixing the L-shaped rod 86 relative to the bracket. The L-shaped rod 86 and the cardboard holder 7 together clamp the carton, increasing the carton's fixation strength on the cardboard holder 7. When the carton needs to be removed, the tightening bolt 88 is loosened, and the L-shaped rod 86 is removed, separating the L-shaped rod 86 from the carton. This allows even long or heavy cartons to be securely clamped onto the cardboard holder 7.

[0038] In the specific setup, the card holder 7 is equivalent to a carton clamp. Depending on the size of the carton, different sizes of card holder 7 can be replaced to match the carton.

[0039] like Figure 2 As shown, the specific connection between the rotating ring 6 and the vertical plate 1 is as follows: the vertical plate 1 is provided with a first protruding ring 61, and the rotating ring 6 is provided with a second protruding ring 16 on the side of the rotating ring 6 away from the support. The second protruding ring 16 is sleeved on the outer circumferential surface of the first protruding ring 61 and rotates with the first protruding ring 61.

[0040] In the specific configuration, the first convex ring 61 and the second convex ring 16 are connected by the bearing 9. The drive assembly 5 is located on one side of the rotating ring 6. The drive assembly 5 includes a drive motor and a reducer located on the power output end of the drive motor. The power output end of the reducer is connected to the outer peripheral surface of the conversion via the belt drive mechanism 4.

[0041] like Figure 1 As shown, the specific connection between the cutter 3 and the vertical plate 1 is as follows: the cutter 3 is provided with a mounting base 31, and the vertical plate 1 is provided with a number of horizontally spaced mounting holes 15 arranged above the rotating ring 6. The mounting base 31 can be detachably connected to any mounting hole 15.

[0042] The assembly method of the mounting base 31 and the mounting hole 15 allows the cutter 3 to change its installation position to match actual needs and cut tape of different lengths.

[0043] Preferably, the cutting blade 3 has serrations on its cutting edge.

[0044] like Figure 1 As shown, in another preferred embodiment, the vertical plate 1 is further provided with a guide roller 12 located between the mounting roller 11 and the rotating ring 6. The guide roller 12 is rotatably engaged with the vertical plate 1, and the height of the guide roller 12 is greater than that of the mounting roller 11.

[0045] The guide roller 12 serves not only to tension the tape, but also to form a fulcrum for the tape's lower helix between the mounting roller 11 and the rotating ring 6, replacing the mounting roller 11 as the fulcrum for the lower helix and preventing the lower helix from disturbing the tape roll 2.

[0046] like Figure 1As shown, in a further improvement, the vertical plate 1 is also provided with a fixed rod 14 and a swing frame 141 provided on the fixed rod 14. The swing frame 141 is rotatably engaged with the fixed rod 14. One end of the fixed rod 14 is connected to the vertical plate 1 and is located between the cutter 3 and the mounting roller shaft 11. A swing roller shaft 142 is provided on the lower side of the swing frame 141. The swing roller shaft 142 is rotatably engaged with the swing frame 141.

[0047] In practical use, as the traction roller shaft 81 continuously pushes the conveyor belt, the conveyor belt changes continuously with the movement of the traction roller shaft 81 until it lifts the swing frame 141 and the swing roller shaft 142. When the conveyor belt is cut by the cutter 3, the conveyor belt and the swing roller shaft 142 swing down together without external force pulling. The swing mass of the swing roller shaft 142 is relatively large, thereby pushing the conveyor belt to swing down below the mounting roller shaft 11.

[0048] Preferably, a positioning block 13 for abutting the swing frame 141 is provided on the side of the swing frame 141 away from the cutter 3.

[0049] The positioning block 13 is designed to prevent the swing frame 141 from driving the roller to swing excessively, thus preventing the conveyor belt from deviating.

[0050] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
