[0002] Widely used in the packaging industry, box taping machines are specialized equipment for producing cartons. They fold, glue, and secure pre-printed cardboard or paper sheets to predetermined dimensions and shapes, ultimately creating finished cartons. These machines are widely used in the packaging industry and are capable of efficiently producing a wide variety of box types and sizes.

[0003] Current packaging box edge taping machines are typically suitable for taping square paper boxes. However, for taping round boxes, manual taping is often used due to the low usage and relatively low production volume of round packaging. This is inefficient and prone to errors, resulting in low yield rates. Round packaging boxes are typically cylindrical and typically consist of a rigid cylindrical blank. Facing paper is attached to the outside of the blank, and the edges that extend beyond the blank need to be bent into the blank for taping.

DETAILED DESCRIPTION

[0021] In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the following is a detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings:

[0022] Example:

[0023] like Figures 1 to 2The utility model provides a edging device for a circular packaging box, comprising a base 1. When packaging a circular or irregularly shaped packaging box, such as a cylinder with a triangular cross-section, facial tissue is attached around the surface of the packaging box in advance. Usually, an edge of the facial tissue is left at the end of the packaging box, and the edge of the facial tissue needs to be edged. A cutting mechanism 2 for cutting the facial tissue of the packaging box is fixedly connected to the base 1. The cutting mechanism 2 includes a first back plate 21, a support plate 22, a fixed plate 23 and a blade 24. The first back plate 21 is fixedly connected to one side of the base 1 and is vertically connected to the base 1. The fixed plate 23 is fixedly connected to the upper end face of the base 1, and one end of the support plate 22 is fixedly connected to the first back plate 21. The fixed plate 23 is fixedly connected to the first back plate 21 and is located directly above the support plate 22. The blade 24 is fixedly connected to the fixed plate 23, and the cutting edge side of the blade 24 points to the support plate 22. During use, a round or irregularly shaped packaging box is placed on the fixing plate 23 and pushed toward the first back plate 21. The angle between the blade 24 and the support plate 22 cuts the tissue paper at the edge of the packaging box. The angle between the blade 24 and the support plate 22 is acute. A roller 221 is embedded on the side of the support plate 22 near the blade 24. The rotation of the roller 221 allows the packaging box to slide smoothly toward the blade 24.

[0024] As another example, Figure 1 and Figure 3 As described above, a pressure plate 31 is elastically connected to the base 1 of the present application, and the pressure plate 31 is used to bend facial tissue. A slide groove 32 is provided on the side of the first back plate 21 close to the support plate 22, and the pressure plate 31 slides in the slide groove 32. A telescopic rod 33 is fixedly connected between the top wall of the slide groove 32 and the pressure plate 31, and a spring 34 is provided on the outer sleeve of the telescopic rod 33. The end face of the pressure plate 31 away from the first back plate 21 is arc-shaped, and the telescopic rod 33 is composed of two or more mutually connected rods. When in use, the edge of the cut facial tissue is pressed down along the end of the pressure plate 31 and pushed toward the side of the first back plate 21, so that the bent facial tissue is further bent toward the inside of the packaging box.

[0025] As another example, Figure 1 and Figure 4The base 1 of the present application is further provided with a fixing assembly 4 for securing the packaging box. The fixing assembly 4 includes a second back plate 41, a cross groove 42, a side strip 43, a latch 44, and a card plate 45. The cross groove 42 is provided on the second back plate 41. The cross groove 42 is two mutually perpendicular grooves with their midpoints coinciding. The side strip 43 is elastically connected to one side of each extended side of the cross groove 42. No side strip 43 is provided at the intersection of the cross grooves 42. The side strip 43 is provided at the extension of the cross groove 42 except at the intersection. Each extended end of the cross groove 42 is provided with a side strip 43 on only one side. The side strip 43 is connected to a telescopic spring in the cross groove 42 to achieve an elastic connection. The latch 44 is fixedly connected to the side strip 43. The card plate 45 slides up and down or left and right in the cross groove 42, and the card plate 45 engages with the latch 44. The latch 44 can be retracted within the edge of the cross groove 42. The edge of the latch 44 or the card plate 45 is an arc-shaped edge. A pull rod can be fixedly connected to the side strip 43 for easy pulling. The clamping plate 45 is completely outward on the side away from the second back panel 41, making it easy for the packaging box to fit between the clamping plates 45. During use, the side strip 43 is pulled downward or left and right until the edge of the latching teeth 44 is lower than the edge of the cross slot 42. The clamping plate 45 can now slide within the cross slot 42. Once it is in the desired position, the side strip 43 is released, and the latching teeth 44 lock the clamping plate 45, locking the packaging box between the clamping plates 45 and securing it. Since the diameter of the packaging boxes in the same batch is the same during production, the position of the clamping plates 45 only needs to be adjusted at the beginning of the batch change.

[0026] As another example, Figure 1 and Figure 5 As described above, the base 1 of the present application is movably connected to a rotating shaft 5 on the side opposite the fixed component 4. A border mechanism 6 for bordering the tissue paper is slidably connected to the rotating shaft 5. The border mechanism 6 is movably connected to the packaging box fixed to the fixed component 4. The border mechanism 6 includes a disk 61, a plurality of openings 62, and a border rod 63. The rotating shaft 5 is rotatably connected to the base 1 and is perpendicular to the second back plate 41. The center of the disk 61 slides on the rotating shaft 5. A plurality of openings 62 are evenly spaced along the diameter of the disk 61. The border rod 63 is embedded in the opening 62. The diameter of the border rod 63 is smaller than the diameter of the opening 62. A plurality of fixing grooves 51 are evenly spaced on the surface of the rotating shaft 5. The center of the disk 61 engages with the fixing groove 51. The edge of the opening 62 and the end of the edge rod 63 near the opening 62 are both fixedly connected to a limit ring 64. The limit ring 64 is made of rubber or an integrally molded hard ring. The hard ring reduces the distance between the opening 62 and the edge rod 63 to achieve an interference fit. The edge rod 63 can be inserted into different openings 62 to adjust the distance between the edge rods 63. The smaller the diameter of the opening 62 and the smaller the diameter of the edge rod 63, the more precise the adjustment of the distance between the edge rods 63. The retaining groove 51 on the rotating shaft 5 allows the disc 61 to slide on the rotating shaft 5 and also allows the disc 61 to rotate as the rotating shaft 5 rotates.

[0027] When in use, the edging rod 63 is inserted into the opening 62 that matches the inner diameter of the packaging box. The spacing between the edging rods 63 matches the inner diameter of the packaging box. The motor is turned on to drive the rotating shaft 5 to rotate. Since the rotating shaft 5 is provided with a fixing groove 51 and engages with the disc 61, the edging rod 63 can rotate on the inner wall of the packaging box, and the facial tissue that has been folded into the packaging box is evenly attached to the inner wall of the packaging box.

[0028] One end of the rotating shaft 5 away from the second back plate 41 is fixedly connected to the output end of the motor, and the motor is fixed on the base 1 .

[0029] The present application discloses a device for edge-binding a circular packaging box. The device operates as follows: during use, a packaging box with tissue paper attached is placed on a fixed plate 23 and pushed toward a first back plate 21. The angle between a blade 24 and a support plate 22 cuts the tissue paper at the edge of the packaging box. The rotation of a roller 221 allows the packaging box to slide more smoothly toward the blade 24. The packaging box is moved to a pressing plate 31, and the cut tissue paper edge is pressed down along the end of the pressing plate 31 and pushed toward the first back plate 21, causing the bent tissue paper to be further bent inward of the packaging box. This bending can be repeated multiple times. During the initial production of each batch of identical packaging boxes, the position of the clip 45 is adjusted. Specifically, the edge strip 43 is pulled downward or left and right so that the edge of the latch 44 is lower than the edge of the cross slot 42. At this point, the clip 45 can slide within the cross slot 42. Once the box is moved to the appropriate position, the edge strip 43 is released, and the latch 44 engages the clip 45, securing the packaging box between the clips 45. Insert the edge rods 63 into the openings 62 that match the inner diameter of the packaging box. The spacing between the edge rods 63 matches the inner diameter of the packaging box. Turn on the motor to drive the rotating shaft 5 to rotate. Since the rotating shaft 5 is provided with a fixing groove 51 and engages with the disc 61, the edge rods 63 can rotate on the inner wall of the packaging box, and the facial tissue that has been folded into the packaging box is evenly attached to the inner wall of the packaging box.
