Description

Technical Field

[0001] This utility model relates to the field of packaging box production technology, and in particular to a tape applicator for packaging box paper. Background Technology

[0002] In the production of packaging boxes, tape is often applied to the cardboard to connect the boxes. Currently, this is typically done manually. However, manual methods are inefficient, increase production costs, and hinder automated production. Furthermore, manual tape application is often inconsistent in quality, prone to errors, and difficult to control, resulting in inconsistent tape placement and affecting the overall appearance of the product. Therefore, automated production lines for packaging boxes require a mechanism that can quickly and efficiently apply tape to the boxes, improving both efficiency and quality. Summary of the Invention

[0003] The purpose of this utility model is to provide a tape-applying mechanism for packaging boxes, so as to solve the problem of manual tape application, improve the efficiency and quality of tape application, and meet the requirements of automated production lines for packaging boxes.

[0004] To achieve the above objectives, this utility model is implemented as follows: A tape-applying mechanism for packaging paper includes a base, a connecting base plate, a tape-guiding device and a tape reel rotatably mounted on the upper part of the connecting base plate, the tape-guiding device including a support rod, the middle part of the support rod being positioned and connected to the axis of the tape reel, and one end of the support rod extending obliquely upwards to the outside of the tape reel, a tape-guiding wheel rotatably mounted on the outside of the support rod, the connecting base plate having multiple guide wheels and a pair of tape-feeding wheels arranged vertically opposite each other on the same side of the tape-guiding wheels, a gap for tape to pass through between the upper and lower tape-feeding wheels, the tape drawn from the tape reel being guided by the tape-guiding wheels, wound around the multiple guide wheels and then fed into the gap between the tape-feeding wheels, and so on. The conveyor belt pulley drives the conveyor belt to move through relative rotation. A tape cutting device and a tape pressing device are sequentially arranged at the rear end of the conveyor belt pulley. The tape pressing device includes a vertically movable tape pressing seat, with a rotatably mounted tape pressing wheel between the tape pressing seats. Sensors with a downward sensing direction are located at both ends of the tape pressing seat. The tape pressing seat also has a spring-loaded pressure rod located in front of the front sensor, with its lower end protruding above the surface of the tape pressing wheel. When the packaging paper passes the front sensor, the tape pressing seat presses down, and the tape pressing seat drives the pressure rod to press the conveyor belt onto the packaging paper, ensuring the tape adheres to the conveyor belt and is further pressed and tightened by the tape pressing wheel. When the packaging paper passes the rear sensor, the tape cutting device presses down to cut the tape.

[0005] Furthermore, the plurality of guide wheels include a first guide wheel, a second guide wheel, and a third guide wheel. The first guide wheel, the second guide wheel, and the third guide wheel are sequentially mounted on the connecting base plate from top to bottom, and all are rotatably mounted. The mounting height of the third guide wheel is lower than the height of the gap between the tape feed wheels, so that the tape forms an upward bending direction when guided by the third guide wheel, making it less likely for the tape to come loose during the application and cutting process.

[0006] Furthermore, a guide positioning plate is provided on the rear side of the conveyor belt pulley, which is inclined downward. The guide positioning plate has an opening for positioning the conveyor belt. After the conveyor belt is conveyed by the conveyor belt pulley, it is positioned through the opening on the guide positioning plate.

[0007] Furthermore, the rear end of the guide positioning plate is also provided with a limiting plate, which is used to limit the tape below the limiting plate, thereby ensuring that the tape remains horizontal before being pasted onto the packaging box paper.

[0008] Furthermore, a fourth guide wheel is provided between the guide positioning plate and the limiting plate, and the tape positioned from the guide positioning plate is guided to the bottom of the limiting plate through the fourth guide wheel.

[0009] Furthermore, the pressing device also includes a first cylinder seat and a first cylinder. The first cylinder seat is fixed by a connecting base plate, and the first cylinder is fixed by the first cylinder seat. The telescopic rod end of the first cylinder is connected to the pressing seat through the first cylinder seat. Through the first cylinder, the pressing seat can press the tape downward or release the tape upward.

[0010] Furthermore, the tape cutting device includes a second cylinder seat, a second cylinder, and a cutter. The second cylinder seat is fixed by a connecting base plate, and the second cylinder is fixed by the second cylinder seat. The telescopic rod end of the second cylinder is connected to the cutter through the second cylinder seat. The cutter cuts the tape downward through the second cylinder.

[0011] Furthermore, the elastic connecting device of the pressure rod is a pressure spring. As the pressure seat moves downwards, because the lower end of the pressure rod connected to the pressure spring is higher than the surface of the pressure roller, the pressure rod preferentially presses the tape down, causing the tape to contact the surface of the packaging paper on the conveyor line, thus initially adhering the tape to the surface of the packaging paper. As the pressure seat presses down further, the pressure rod, which preferentially presses against the tape, contracts through the pressure spring, making the height of contact between the pressure rod and the pressure roller consistent. In this process, the pressure rod initially presses the tape tightly, and the pressure roller further presses the tape firmly against the surface of the packaging paper.

[0012] Furthermore, a transmission motor is coaxially connected to the pressure roller. The transmission motor causes the upper and lower opposing pressure rollers to rotate synchronously in opposite directions, thus providing the power for the tape to move. This allows the tape on the tape reel to rotate under the pull of the feed roller, continuously drawing out the tape and ensuring that the tape moves synchronously with the packaging paper moving on the conveyor line.

[0013] In this invention, the tape-applying mechanism for packaging paper is connected to one side of the packaging paper conveyor line via a connecting base plate. This allows the pressing and cutting devices mounted on the connecting base plate to be positioned above the conveyor line. When the packaging paper passes the sensor at the front end of the tape-applying mechanism, the sensor controls the first cylinder to move the pressing seat downwards. Since the lower end of the pressing rod is higher than the surface of the pressing wheel, the pressing rod first presses down the tape during the pressing process, causing the tape to adhere to the surface of the packaging paper. As the pressing seat presses down further, the pressing rod contracts due to the action of the pressing spring, keeping the pressing rod and the pressing wheel at the same horizontal plane. The pressing wheel rolls to continuously apply tape to the moving packaging paper. When the packaging paper passes the sensor at the rear end, the sensor controls the second cylinder to press down the cutter. During the pressing process, the cutter cuts the tape at the front end. After the tape is cut, the first and second cylinders lift, causing the pressing and cutting devices to detach from the surface of the conveyor line, and the system awaits the tape-applying process for the next packaging paper.

[0014] This invention effectively utilizes the transmission line to move the tape after it has been applied to the packaging box. During the movement of the tape, the transmission motor further provides power by rotating the upper and lower tape feeding rollers, allowing the tape on the tape reel to rotate continuously under the pull of the tape feeding rollers. This ensures continuous tape application and realizes the automatic tape application process for packaging boxes, greatly improving the efficiency and quality of tape application.

Detailed Implementation

[0022] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0023] A tape applicator for packaging boxes. Figure 1 , Figure 2 , Figure 3The system includes a base 1, a connecting base plate 11, a guide belt device 3 and a rotatably mounted tape reel 2 on the upper part of the connecting base plate 11, and tape 4 for attaching packaging boxes on the tape reel 2. The guide belt device 3 includes a support rod 31, the middle of which is positioned and connected to the axis of the tape reel 2, and one end of the support rod 31 extends obliquely upwards to the outside of the tape reel 2. A guide roller 32 is rotatably mounted on the outside of the support rod 31. To better balance the support rod 31, a guide roller 32 is connected to the support rod 31 on the side away from the guide roller 32. A balance spring 33 is provided to balance the support rod 31. The connecting base plate 11 is provided with multiple guide wheels and a pair of vertically opposite tape feed rollers 15 on the same side as the guide roller 32. A gap is left between the upper and lower tape feed rollers 15 for the tape 4 to pass through. The tape 4 led out from the tape reel 2 is guided by the guide roller 32 and then wound around the multiple guide wheels before being fed into the gap between the tape feed rollers 15. The tape feed rollers 15 drive the tape 4 to move by rotating relative to each other. The rear end of the tape feed rollers 15 is provided with a tape cutting device 6 and a tape pressing device 5 in sequence.

[0024] The guide wheels include a first guide wheel 12, a second guide wheel 13, and a third guide wheel 14. These guide wheels are mounted sequentially from top to bottom on the connecting base plate 11 and are all rotatably mounted. The mounting height of the third guide wheel 14 is lower than the height of the gap between the tape feed rollers 15, causing the tape 4 to bend upwards when guided by the third guide wheel 14. This prevents the tape 4 from easily coming loose during the application and cutting process. To better guide and position the tape 4, the tape feed rollers 15... A guide positioning plate 16 is provided on the rear side at an angle downward. The guide positioning plate 16 has an opening for positioning the tape 4. After the tape 4 is conveyed by the tape feeding wheel 15, it is positioned through the opening on the guide positioning plate 16. A limiting plate 18 is also provided at the rear end of the guide positioning plate 16. A fourth guide wheel 17 is provided between the guide positioning plate 16 and the limiting plate 18. After the tape 4 is positioned by the guide positioning plate 16, it is guided by the fourth guide wheel 17 to the bottom of the limiting plate 18. The limiting plate 18 is used to limit the tape 4 to the bottom of the limiting plate 18, thereby ensuring that the tape 4 remains horizontal before being pasted on the packaging box paper.

[0025] In this embodiment, a transmission motor 7 is coaxially connected to the pressure roller 52. The transmission motor 7 causes the pressure rollers 52, which are arranged vertically opposite to each other, to rotate synchronously in opposite directions. This enables the pressure rollers 52 to provide the power to move the tape 4, so that the tape 4 on the tape reel 2 can rotate under the pull of the tape feeding roller 52 and continuously draw out the tape 4. At the same time, it ensures that the tape 4 can move synchronously with the packaging paper moving on the transmission line, thus achieving the purpose of connecting the front and the back.

[0026] Reference Figure 4 , Figure 5The pressing device 5 includes a pressing seat 51 that can move up and down, with a rotatable pressing wheel 52 installed between the pressing seats 51. The pressing device 5 also includes a first cylinder seat 54 and a first cylinder 53. The first cylinder seat 54 is fixed by a connecting base plate 11, and the first cylinder 53 is fixed by the first cylinder seat 54. The telescopic rod end of the first cylinder 53 is connected to the pressing seat 51 through the first cylinder seat 54. Through the first cylinder 53, the pressing seat 51 can press the tape 4 downward or release the tape 4 upward. The front and rear ends of the pressing seat 51 are provided with sensors 57 with the sensing direction facing downward. The pressing seat 51 is also provided with a spring 55 that is elastically connected. Preferably, the elastic connection device is a pressing spring 56, and the spring 55 is... Located in front of the sensor 57 at the front end, the lower end of the pressure rod 55 is higher than the surface of the pressure roller 52. When the packaging paper passes through the sensor 57 at the front end, the sensor 57 controls the first cylinder 53 to move the pressure seat 51 downward. The pressure seat 51 presses down, and the pressure rod 55 first presses the tape 4 onto the packaging paper, so that the tape 4 is attached to the packaging paper on the conveyor line. After the pressure seat 51 presses down further, the pressure rod 55, which first presses against the tape 4, is contracted by the pressure spring 56, so that the pressure rod 55 and the pressure roller 52 are at the same height. In this process, the pressure rod 55 initially presses the tape 4, and the pressure roller 52 further presses the tape 4 onto the surface of the packaging paper.

[0027] Reference Figure 6 The tape cutting device 6 includes a second cylinder seat 62, a second cylinder 61, and a cutter 63. The second cylinder seat 62 is fixed by a connecting base plate 11, and the second cylinder 61 is fixed by the second cylinder seat 62. The telescopic rod end of the second cylinder 61 is connected to the cutter 63 through the second cylinder seat 62. When the packaging paper passes the sensor 57 at the rear end, the sensor 57 at the rear end controls the second cylinder 61 to press down the cutter 63. During the pressing down process, the cutter 63 cuts the tape 4 at the front end. After the tape 4 is cut, the first cylinder 53 and the second cylinder 61 are raised so that the tape pressing device 5 and the tape cutting device 6 are removed from the surface of the transmission line, and wait for the tape application process of the next packaging paper.

[0028] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
