Description

[0001] This application claims priority to the utility model application filed on August 22, 2024, with application number 202422047180.0 and entitled "A Brush Sliding Telescopic Device for an Automatic Tape Sealing Packaging Machine". Technical Field

[0002] This utility model relates to a tape sealing and packaging machine, and in particular to a tape bonding mechanism and a brush sliding and telescopic device for an automatic tape sealing and packaging machine, belonging to the technical field of packaging equipment. Background Technology

[0003] With the development of the times, online shopping has become increasingly popular. However, before online purchases can be shipped via logistics and express delivery, they need to be packaged and sealed, which requires the use of tape. Traditionally, people manually wrap the tape around the box in a full circle or a cross shape, which is cumbersome, laborious, and inefficient. Therefore, automatic tape sealing equipment was invented. However, this type of equipment can usually only automatically seal the top and bottom openings of the box, and cannot seal the entire box with tape. Furthermore, the tape may not adhere tightly during sealing, which can easily cause the contents of the box to fall out. Therefore, the applicant previously applied for Chinese Utility Model Patent 202320766330.6, entitled "Improved Tape Sealing Packaging Machine." This structure combines a tape winding and rotating device, an automatic tape cutting and releasing device, a platform bridging structure, a linked packaging box bottom brush flattening and sliding tape bonding device, and a brush fixed-point telescopic limiting device. During the tape winding and sealing process, the tape at the bottom of the packaging box is flattened and bonded, resulting in a tighter adhesion between the tape and the packaging box. However, the linked packaging box bottom brush in this patent... The brush rod in the flattening and sliding tape bonding device is rotatably connected to the rear connecting seat via a pivot pin. By rotating and swinging the brush left and right, it flattens the tape at the bottom of the packaging box. Its disadvantages are: the brush head stroke is short, making it suitable for small tape sealing and packaging machines. If it is to be used in large tape sealing and packaging machines, the brush rod length is increased, resulting in a large size and weight. The brush rod has a large inertia when it rotates and swings rapidly for a long time, and the pivot pin position is unstable, which is prone to shaking and instability, leading to damage at that position and a short service life. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a brush sliding telescopic device for an automatic tape sealing and packaging machine, which has a long brush travel, more stable and reliable left-right movement and forward-backward extension action, and improves the service life of the whole machine.

[0023] Furthermore, the skateboard is provided with two sets of front and rear guide rods, and the dual slider sliding device is respectively provided on the two sets of front and rear guide rods.

[0024] Furthermore, a fixing plate is provided on the skateboard, an inclined guide plate is provided on the fixing plate, and a roller is provided at one end of the brush rod. The roller cooperates with the inclined guide plate to make the brush rod swing at a predetermined angle.

[0025] Furthermore, the brush sliding telescopic device of the automatic tape sealing packaging machine also includes a fixed plate, and a limiting stop is provided at the middle part of the fixed plate corresponding to the central notch. The limiting stop cooperates with the front bearing when moving from right to left.

[0026] A tape bonding mechanism includes the aforementioned brush sliding telescopic device.

[0027] An automatic tape sealing and packaging machine includes the tape laminating mechanism.

[0028] The beneficial effects of the brush sliding telescopic device of this utility model for an automatic tape sealing and packaging machine are as follows: First, the cooperation between the sliding plate and the first guide rod allows the sliding plate and the double slider sliding device to slide linearly left and right. The brush on the double slider sliding device can brush the tape at the bottom of the packaging box in a linear manner from left to right. The brush has less inertia during operation, making the movement more stable and reliable, and improving the service life of the whole machine. Second, through the guidance and cooperation between the front guide device and the front bearing under the front slider, and the guidance and cooperation between the rear guide device and the rear bearing under the rear slider, combined with the tension of the first and second tension springs and the cooperation of the lifting structure, the brush can extend and retract back and forth. When the brush extends forward, it can brush the tape at the bottom of the packaging box. When the brush retracts, it can avoid interfering with the tape covering the packaging box. The movement is smooth, stable, and reliable. The ingenious design of the linkage of each moving part minimizes the use of cylinders, motors, and other power structures, reducing manufacturing costs and reducing the entanglement of pipelines and lines.

[0040] This utility model relates to an automatic tape sealing and packaging machine, such as... Figure 10 and Figure 11 The automatic tape sealing packaging machine can wrap and seal packaging boxes with tape. The automatic tape sealing packaging machine realizes the tape end to be attached to the packaging box through the tape bonding mechanism. The tape bonding mechanism controls the extension and sliding of the brush during the sealing process through the brush sliding telescopic device to realize the automatic attachment of the tape end to the packaging box.

[0041] For example, such as Figures 1-9 As shown, the brush sliding telescopic device of this utility model includes a fixed frame 1, a turntable 11 is provided on the front side of the fixed frame 1, and an adhesive tape fixing ring 12 is provided on the turntable 11. The turntable 11 is driven to rotate by a power source. Two left and right brackets 13 are provided on the back of the fixed frame 1. A first guide rod 41 and a fixing plate 42 are provided between the left and right brackets 13. A sliding plate 43 is provided on the first guide rod 41. The sliding plate 43 is driven to slide left and right along the first guide rod 41 by a power source. In this embodiment, the sliding plate 43 is linked to the turntable 11, that is, the power for the sliding plate 43 to slide comes from the turntable 11. While the turntable 11 is rotating, it can drive the sliding plate 43 to slide along the first guide rod 41. The slide plate 43 is provided with front and rear guide rods 46, and a double slider sliding device is provided on the front and rear guide rods 46. The double slider sliding device includes a front slider 461 and a rear slider 462, which can slide back and forth along the front and rear guide rods 46 respectively. A first tension spring 463 is provided between the front slider 461 and the rear slider 462, and a second tension spring 464 is provided between the rear slider 462 and the front part of the slide plate 43. A brush rod 465 is provided on one side of the front slider 461, and brush bristles 466 are provided on the end of the brush rod 465 away from the front slider 461. A front bearing 467 is provided at the lower part of the front slider 461, and a rear bearing 468 is provided at the lower part of the rear slider 462. A front guide device for guiding the front slider 461 and a rear guide device for guiding the rear slider 462 are provided on the fixed plate 42. The front guide device guides and cooperates with the front bearing 467 under the front slider 461, and the rear guide device guides and cooperates with the rear bearing 468 under the rear slider 462.

[0042] Furthermore, the front guide device includes a horizontally arranged front guide plate 421, which is fixed to a fixed plate 42. A left notch 422 and a right notch 423 are provided in the front guide plate 421. A left front lifting baffle 424 is provided in the left notch 422, and a right front lifting baffle 425 is provided in the right notch 423. The left front lifting baffle 424 and the right front lifting baffle 425 are driven to rise or fall by a lifting structure. In this embodiment, the left front lifting baffle 424 and the right front lifting baffle 425 are linked with the turntable 11. That is, the power for the left front lifting baffle 424 and the right front lifting baffle 425 to rise and fall comes from the turntable 11. When the turntable 11 rotates to a specific angle, it can drive the left front lifting baffle 424 and the right front lifting baffle 425 to perform lifting and lowering actions. Along the sliding direction of the slide plate 43, the front bearing 467 at the lower part of the front slider 461 can respectively cooperate with the front guide plate 421, the left notch 422, the right notch 423, the left front lifting baffle 424, and the right front lifting baffle 425. The rear guide device includes a roughly V-shaped middle guide plate 426 and a laterally arranged rear guide plate 427. The middle guide plate 426 and the rear guide plate 427 are respectively fixed to the fixed plate 42. The middle guide plate 426 is provided with a middle-rear plate connecting structure in the middle, and the rear guide plate 427 is provided with a middle notch 428 in the middle. The middle of the middle guide plate 426 is connected to the rear guide plate 427 through the middle-rear plate connecting structure and the middle notch 428. The two ends of the rear guide plate 427 are respectively provided with left rear lifting baffles. The left and right rear lifting baffles 429 and 430 are raised or lowered by a lifting structure. In this embodiment, the left and right rear lifting baffles 429 and 430 are linked to the turntable 11, meaning that the power for raising and lowering the left and right rear lifting baffles 429 and 430 comes from the turntable 11. When the turntable 11 rotates to a specific angle, it can drive the left and right rear lifting baffles 429 and 430 to perform raising and lowering actions. Furthermore, the left and right rear lifting baffles 429, 430, left and right front lifting baffles 424, and right front lifting baffles 425 all move synchronously with the drive of the turntable 11. Along the sliding direction of the slide plate 43, the rear bearing 468 at the lower part of the rear slider 462 can respectively cooperate with the middle guide plate 426, the middle and rear plate connecting structure, the rear guide plate 427, the left rear lifting baffle 429 and the right rear lifting baffle 430.

[0043] The left rear lifting baffle 429, the right rear lifting baffle 430, the left front lifting baffle 424, and the right front lifting baffle 425 are components of the lifting structure and are used to cooperate with the front guide device and the rear guide device to limit the movement trajectory of the double slider sliding device.

[0044] Furthermore, the lifting structure includes a left front lifting baffle 424 located below the fixed plate 42, with a left front connecting plate 431 rotatably connected to the front guide plate 421 via a central pivot pin; a right front lifting baffle 425 located below the fixed plate 42, with a right front connecting plate 432 rotatably connected to the front guide plate 421 via a central pivot pin; and a structure between the left rear lifting baffle 429 and the right rear lifting baffle 430. A linkage lever 433 is located below the fixed plate 42. A pin at the center of the linkage lever 433 is rotatably connected to the lower part of the fixed plate 42. A left connecting rod 434 is provided between the end of the left front linkage plate 431 away from the left front lifting baffle 424 and the lower part of the left rear lifting baffle 429. A right connecting rod 435 is provided between the end of the right front linkage plate 432 away from the right front lifting baffle 425 and the lower part of the right rear lifting baffle 430. The fixed frame... A front lever 14 is provided on the front side. The middle part of the front lever 14 is rotatably connected to the fixing frame 1 via a pin. One end of the front lever 14 is connected to the left connecting rod 434, and the other end of the front lever 14 is connected to the right connecting rod 435. A left lever 141 is provided at one end of the front lever 14 and is fixed to the front lever 14 by fasteners. A lever 142 is provided at the other end of the front lever 14. A right lever 143 is provided on the fixing frame 1 in front of the lever 142. The paddle 143 is rotatably connected to the fixed frame 1 via a pin. The right paddle 143 has a paddle hole 144, and the lever 142 engages with the paddle hole 144. The distance S1 between the left paddle 141 and the front lever 14 is greater than the distance S2 between the right paddle 143 and the front lever 14. The turntable 11 is equipped with a long paddle pin 145 and a short paddle pin 146. The long paddle pin 145 engages with the left paddle 141, and the short paddle pin 146 engages with the right paddle 143. The larger distance between the left paddle 141 and the front lever 14 prevents the short paddle pin 146 from hitting the left paddle 141 when passing through, thus preventing premature swinging of the front lever 14 and affecting the overall movement. Alternatively, the lifting structure can use a solenoid valve. The solenoid valve connects the front lifting baffle 424 and the left rear lifting baffle 429, controlling their rise or fall. However, this circuit control setup is more complex and costly.

[0045] Furthermore, the aforementioned middle and rear plate connection structure includes a mounting groove 436 in the middle of the middle guide plate 426, a pull pin 437 in the mounting groove 436, a transition plate 438 above the opening of the mounting groove 436, a swing plate 439 between the transition plate 438 and the mounting groove 436, a third tension spring 440 connecting one end of the swing plate 439 to the pull pin 437, and the other end of the swing plate 439 connecting to the rear guide plate 427 via a middle notch 428. Alternatively, two middle lifting baffles can be installed in the middle notch 428, connected by a solenoid valve, and the raising or lowering of the middle lifting baffles can be controlled by the solenoid valve. However, since the raising and lowering of the middle lifting baffles requires higher precision in timing with the front bearing 467 and the rear bearing 468, the circuit control settings are more complicated and costly.

[0046] Furthermore, the slide plate 43 is equipped with two sets of front and rear guide rods 46, each with a double-slider sliding device. With two sets of double-slider sliding devices, there are also two sets of brush rods 465 and brush bristles 466. However, when smoothing the tape at the bottom of the packaging box, not both sets of brush rods 465 and brush bristles 466 extend simultaneously. When the slide plate 43 is to the left of the first guide rod 41, the left set of double-slider sliding devices extends the brush rods 465 and brush bristles 466, driving the slide plate 43 to gradually move to the right. The slide plate 43 then uses the brush rods 465 and brush bristles 466 of the left double-slider sliding device to smooth the tape at the bottom of the packaging box for the first time. Meanwhile, the brush rods 465 and brush bristles 466 of the right double-slider sliding device only... The brush rod 465 and brush bristles 466 in the left double slider sliding device retract to their original positions under the guidance of the front and rear guide devices, while the brush rod 465 and brush bristles 466 in the right double slider sliding device extend forward under the action of the lifting structure. At this time, the brush rod 465 and brush bristles 466 in the right double slider sliding device extend forward and are driven to the left by the slide plate 43 to brush the tape at the bottom of the packaging box for the second time. The brush rod 465 and brush bristles 466 in the left double slider sliding device simply follow the slide plate 43 to the left and do not extend.

[0047] Furthermore, a fixing plate 45 is provided on the sliding plate 43, and an inclined guide plate 451 is provided on the fixing plate 45. A roller 452 is provided at the end of the brush rod 465 away from the bristles 466, and the roller 452 cooperates with the inclined guide plate 451. When the current slider 461 drives the brush rod 465 forward (the brush rod 465 is rotatably connected to the front slider 461 via a pin; in normal state, the bristles 466 at the head of the brush rod 465 are slightly tilted downwards), causing the bristles 466 to extend forward, the roller 452 on the brush rod 465 cooperates with the inclined guide plate 451. Under the guidance of the inclined guide plate 451, the end of the brush rod 465 located at the roller 452 rotates downwards, while the end of the brush rod 465 located at the bristles 466 rotates upwards, causing... After the bristles 466 extend, they can get closer to the tape at the bottom of the packaging box, smoothing the tape and making the tape adhere more reliably to the bottom of the packaging box. When the slider 461 drives the brush rod 465 to return to its original position, the roller 452 disengages from the inclined guide plate 451, and the front of the brush rod 465 rotates downward under the action of gravity, so that the brush rod 465 and the bristles 466 return to a horizontal state (a support plate can be set under the brush rod 465 to limit the brush rod 465 and prevent excessive downward rotation).

[0048] Furthermore, a limiting stop 453 is provided at the middle part of the fixed plate 42 corresponding to the middle notch 428, and the limiting stop 453 cooperates with the front bearing 467 when moving from right to left. Without the limit stop 453, when the slide plate 43 drives the double slider sliding device to move from right to left, the rear bearing 468 under the rear slider 462 of the double slider sliding device will move forward along the middle notch 428 to the transition plate 438 when passing the middle notch 428, and then return to the corresponding position of the rear guide plate 427 along the swing plate 439. This causes the rear slider 462 and the front slider 461 to fluctuate back and forth at this position. With the limit stop 453, when the front and rear sliders 461 and 462 move to this position, the front bearing 467 under the front slider 461 contacts the limit stop 453. The front bearing 467 drives the front slider 461, and the front slider 461 pushes against the rear slider 462, so that the front and rear sliders 461 and 462 will not fluctuate back and forth at the middle notch 428, making the transition smoother and the operation more reliable.

[0049] In the above embodiments, the brush rod 465 is disposed on the double slider sliding device. The two cooperate with the slide plate 43, the first guide rod 41, the front guide device, the rear guide device, and the lifting structure to form a tape bonding mechanism, thereby realizing the automatic bonding of the tape end to the packaging box.

[0050] This utility model discloses a brush sliding telescopic device for an automatic tape sealing and packaging machine. In use, first, the tape roll is fitted onto the tape fixing ring 12, and the tape head is pulled out (the adhesive side of the tape should be facing up, and the smooth side down). Then, the automatic tape cutting and releasing device 101 (the specific structure of the automatic tape cutting and releasing device 101 is existing technology; it can clamp or release the tape, and can also cut the tape) is opened by hand, and the tape head is clamped by the automatic tape cutting and releasing device 101. Next, the packaging box is placed on the platform bridging structure 102 (the specific structure of the platform bridging structure 102 is existing technology; it is used to place the packaging box, and there is a gap in the middle of the platform bridging structure 102 for the tape to pass over). The machine is then powered... The turntable 11 is rotated (teeth are made on the outer ring of the turntable 11, and an inner ring bearing is set on the inner ring of the turntable 11. The motor drives the gear, which meshes with the teeth of the turntable 11, causing the turntable 11 to rotate around the inner ring of the ring bearing). The turntable 11 drives the tape fixing ring 12 and the tape roll to rotate, so that the tape first sticks to the left side wall of the packaging box. At this time, the short pin 146 contacts one end of the right lever 143, causing the right lever 143 to rotate upward at one end of the lever 142. The lever 142 drives the right side of the front lever 14 to rotate upward. The right side of the front lever 14 drives the right connecting rod 435 to move upward. The right connecting rod 435 drives the right side of the right front connecting plate 432 to rotate upward. The right front lifting baffle 425 on the left side of the right front connecting plate 432 rotates downward, so that the right... When notch 423 opens, the right connecting rod 435 drives the right rear lifting baffle 430 of the connecting lever 433 to rotate upward, causing the left rear lifting baffle 429 of the connecting lever 433 to rotate downward. The left rear lifting baffle 429 then drives the left side of the left front connecting plate 431 to rotate downward through the left connecting rod 434, and the left front lifting baffle 424 on the right side of the left front connecting plate 431 rotates upward, sealing the left notch 422. As the left rear lifting baffle 429 rotates downward, it disengages the rear bearing 468 of the double slider sliding device from the limiting contact. Under the tension of the second tension spring 464, it drives the rear slider 462 and the front slider 461 to slide forward along the front and rear guide rods 46. The front slider 461 drives the brush rod 465 and the brush bristles 466 to extend forward together. When bristles 466 extend forward and lift upward, they align with the tape on the left side of the bottom of the packaging box. Turntable 11 drives the tape roll to continue rotating, while the power source (a motor with gears on its output shaft meshing with a rack, causing linear reciprocating motion, and the rack causing reciprocating motion of slide plate 43) moves slide plate 43 to the right along the first guide rod 41. Slide plate 43 drives bristles 466 to perform the first smoothing of the tape at the bottom of the packaging box. During this smoothing process, the tape automatic cutting and releasing device 101 opens downward to avoid interfering with the bristle movement. As slide plate 43 drives the double slider sliding device to move to the right, the rear bearing 468 of the double slider sliding device contacts the middle guide plate 426, which guides the movement.The rear bearing 468 drives the rear slider 462 to gradually move backward, while the front bearing 467 of the front slider 461 moves laterally along the front guide plate 421, thus creating a distance between the front slider 461 and the rear slider 462. This stretches the first tension spring 463 and the second tension spring 464. When the slide plate 43 moves the front bearing 467 to the right notch 423, the right notch 423 is already open. Under the tension of the first tension spring 463, the front bearing 467 of the front slider 461 moves rapidly backward through the right notch 423 until it contacts the rear slider 462. The front slider 461 then drives the brush rod 465 and brush bristles 466 to retract backward. Returning to the right, the slide plate 43 moves to the far right of the first guide rod 41, and the rear bearing 468 of the double slider sliding device contacts the right rear lifting baffle 430. At this time, the right rear lifting baffle 430 is in an upward state, blocking the rear bearing 468. At this time, driven by the turntable 11, the tape has covered the left bottom, left side, and top surface of the packaging box. After the bristles 466 retract, they can avoid interfering with the tape covering the right side of the packaging box. When the tape covers the right side of the packaging box, the tape automatic cutting and releasing device 101 is released, and the turntable 11 drives the tape roll to wrap around the bottom surface of the packaging box, so that the tape covers the right bottom surface of the packaging box, and the tape is automatically cut. The release device 101 clamps the tape again and cuts it, separating the tape adhered to the packaging box from the tape roll. Then, the turntable 11 drives the long pin 145 to contact the right lever 143 of the front lever 14. The long pin 145 drives the left lever 141 to rotate upward, and the left lever 141 drives the left side of the front lever 14 to rotate upward. The right side of the front lever 14 rotates downward in the opposite direction. The right side of the front lever 14 drives the right connecting rod 435 to move downward. The right connecting rod 435 drives the right rear lifting baffle 430 of the connecting lever 433 to rotate downward, and drives the right front lifting baffle 425 to rise and seal the right notch 423. The left front lifting baffle 425... 24 descends, opening the left notch 422. As the right rear lifting baffle 430 opens and disengages from the limit contact with the rear bearing 468, the second tension spring 464 pulls the rear slider 462 and the front slider 461 forward, causing the brush rod 465 and brush bristles 466 to extend again. The power drives the slide plate 43 and the double slider sliding device to slide to the left, allowing the brush bristles 466 to brush and adhere the tape on the bottom right side of the packaging box. After brushing, the double slider sliding device returns to its initial position, and under the guidance of the front and rear guide devices, the brush rod 465 and brush bristles 466 retract back to their original positions, ready for the next tape brushing action. This solution provides a brush sliding telescopic device for an automatic tape sealing and packaging machine. First, the cooperation between the sliding plate 43 and the first guide rod 41 allows the sliding plate and the double-slider sliding device to slide linearly left and right. The brush on the double-slider sliding device can then smoothly brush the tape at the bottom of the packaging box. This reduces the inertia of the brush during operation, resulting in smoother and more reliable movement, thus extending the overall machine's service life. Second, the device is guided by a front guide device and a front bearing 467 under the front slider 461.The rear guide device cooperates with the rear bearing 468 under the rear slider 462, and combined with the tension of the first tension spring 463 and the second tension spring 464, as well as the lifting structure, allows the brush to extend and retract. When the brush extends forward, it can smooth the tape on the bottom of the packaging box; when the brush retracts, it avoids interfering with the tape's coverage of the packaging box. The operation is smooth, stable, and reliable. The ingenious design of the linkage between various moving parts minimizes the use of cylinders, motors, and other power structures, reducing manufacturing costs and minimizing the entanglement of pipes and wiring.
