Description

Technical Field

[0001] This application belongs to the field of cardboard box strapping and packaging production technology, and specifically relates to a strapping machine for the side of cardboard boxes. Background Technology

[0002] Cardboard boxes are widely used in the packaging and transportation industry due to their advantages such as durability, ease of processing, low cost, recyclability, and environmental friendliness. During the cardboard box processing, the boxes need to be stacked orderly to a certain height before being bundled and secured for transport.

[0003] In the publication document CN222137100U, a strapping device for cartons is disclosed. The screw, limiting plate, nut and slot are designed to facilitate quick docking of the worktable with the first strapping machine or the second strapping machine. Moreover, the adjustment mechanism is designed to adjust the rotation direction of the stacked cartons that have been strapped laterally by the first strapping machine before conveying them to the second strapping machine for further strapping, thereby enabling the strapping of the cartons in the longitudinal direction.

[0004] In the published documents, the binding of an entire side needs to be done on a rotating platform. The inventor believes that setting a rotating platform in the conveyor device requires the carton to be transferred to the rotating platform for alignment. Several problems will occur in this process: the carton will get stuck between the conveyor and the rotating platform, causing the entire conveyor line to jam; when the carton rotates on the rotating platform, the carton will shift its position under the action of centrifugal force, causing the carton to be unable to align with the position of the conveyor when it is output from the rotating platform. Utility Model Content

[0005] The purpose of this invention is to address existing problems by providing a strapping machine that uses a strapping device to provide power and uses tape to wrap around the sides of a carton.

[0006] To achieve the above technical objectives, the following technical solution is provided: a strapping machine for the side of a carton, comprising a support section, on which a belt conveyor is provided, and on which a carton is placed; the support section also comprises a pair of side wing support seats, each of which is provided with a strapping mechanism; the sides of the carton are strapped and glued together by the cooperation of the two strapping mechanisms.

[0007] In one feasible embodiment, the strapping mechanism includes a movable base with a support on the base and a strapping output mechanism on the support, wherein the strapping output direction of the strapping output mechanism is perpendicular to the carton conveying direction of the belt conveyor.

[0008] In one feasible embodiment, the cable tie output mechanism includes a fixed frame disposed on one side of the support and a movable frame movably connected to the other side of the support. A hydraulic rod is hinged between the fixed frame and the movable frame, and the movable frame is rotated by the hydraulic rod to realize the retraction and extension of the movable frame.

[0009] In one feasible implementation, the movable frame is equipped with multiple vertical rollers, wherein the rollers are active rollers; the base is equipped with a cable tie storage ring, and the cable ties on the cable tie storage ring are tied to the carton via the rollers.

[0010] In one feasible method, the roller of the cable tie output mechanism located on the left wing support rotates clockwise, while the roller of the cable tie output mechanism located on the right wing support rotates counterclockwise. The two work together to achieve side rotation and strapping of the carton.

[0011] In one feasible embodiment, a cutting mechanism is provided on the base and is located next to the strapping mechanism. The cutting mechanism includes a track support, a servo motor at the bottom of the track support, an active synchronous pulley on the shaft of the servo motor, a driven synchronous pulley at the top of the track support, a synchronous belt on the active and driven synchronous pulleys, and a cutting element on the synchronous belt. The cutting element extends between the roller components, and the strapping is cut by the moving cutting element when strapping is completed.

[0012] In one feasible implementation, the base is placed on a side wing support, and a pair of telescopic cylinders are provided on one side. The base is moved by the telescopic cylinders to restrict the conveying of the carton.

[0013] In one feasible embodiment, the belt conveyor includes a conveyor belt with omnidirectional conveyor balls evenly distributed on its surface.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The conveying equipment described in this application is a complete conveying system, eliminating the problem of cartons getting stuck on the conveyor during transport. Furthermore, during strapping, the adhesive tape holds the cartons to the rollers, and the rollers themselves rotate the cartons, preventing easy positional changes and maintaining the strapped position on the conveyor. The strapping tape is delivered at a uniform speed and is easily absorbed and passed through the rollers, ensuring it doesn't easily detach. During re-straightening, the cut tape is firmly pressed onto the cartons by the rollers, and then the cartons rotate under the rollers, with the tape still secured to the cartons. The cutting mechanism ensures the tape is cut promptly after strapping. Attached Figure Description

[0019] like Figure 1 The illustrated embodiment provides a strapping machine for the side of a carton, comprising a support 1, a belt conveyor 2 mounted on the support 1, and a carton component 3 placed on the belt conveyor 2. The support 1 also includes a pair of side wing support seats 4, each side wing support seat 4 having a strapping mechanism 5. The two strapping mechanisms 5 work together to strap and bond the surface of the carton component 3. The belt conveyor 2 includes a conveyor belt with omnidirectional conveyor balls evenly distributed on its surface.

[0020] In this embodiment, the strapping mechanism 5 includes a movable base 51, a support 52 mounted on the base 51, and a strapping output mechanism 53 mounted on the support 52. The strapping output direction of the strapping output mechanism 53 is perpendicular to the conveying direction of the carton 3 of the belt conveyor 2. The base 51 is placed on a side wing support 4, and a pair of telescopic cylinders 6 are provided on one side. The telescopic cylinders 6 are used to move the base 51, thereby restricting the conveying of the carton 3.

[0021] In this embodiment, the cable tie output mechanism 53 includes a fixed frame 531 disposed on one side of the support 52, and a movable frame 532 movably connected to the other side of the support 52. A hydraulic rod 533 is hinged between the fixed frame 531 and the movable frame 532, and the movable frame 532 is rotated by the hydraulic rod 533 to realize the retraction and extension of the movable frame 532. Preferably, the movable frame 532 is provided with five vertical rollers, wherein the rollers are active rollers; a cable tie storage ring 54 is provided on the base 51, and the cable ties on the cable tie storage ring 54 are tied to the carton 3 by the rollers.

[0022] like Figure 2As shown in this embodiment, a cutting mechanism 55 is provided on the base 51, and the cutting mechanism 55 is located next to the binding mechanism 5. The cutting mechanism 55 includes a track support 551, a servo motor 552 at the bottom of the track support 551, an active synchronous pulley 553 on the shaft of the servo motor 552, a driven synchronous pulley 554 at the upper part of the track support 551, a synchronous belt 555 on the active synchronous pulley 553 and the driven synchronous pulley 554, a cutting element 556 on the synchronous belt 555, the cutting element 556 extending between the rollers, and cutting the binding tape by the moving cutting element 556 when binding is completed.

[0023] In this embodiment, the roller of the cable tie output mechanism 53 located on the left side wing support 4 rotates clockwise, and the roller of the cable tie output mechanism 53 located on the right side wing support 4 rotates counterclockwise. The two cooperate to realize the side rotation and binding of the carton 3.

[0024] In this embodiment, the working principle is as follows: The cardboard box 3 is conveyed on the belt conveyor 2. When the system detects that the side of the cardboard box 3 is not strapped, the telescopic cylinder 6 starts working, pushing the base 51 towards the belt conveyor 2. Then, the two movable frames 532 cut off the belt conveyor 2. When the cardboard box 3 reaches the strapping mechanism 5, it adheres to the tape on the roller. Then, the active roller starts moving, rotating the cardboard box 3. The strapping tape wraps around the side of the cardboard box 3, and after 2-3 turns, the cardboard box 3 returns to its initial position. The cutting mechanism 55 starts working, and the cutting piece 556 cuts the strapping tape. Then, the telescopic cylinder 6 moves again, opening the conveying channel on the belt conveyor 2 to allow the strapped cardboard box 3 to continue being conveyed. Because some cardboard boxes 3 are large, they cannot pass through even after the telescopic cylinder 6 returns to its original position. In this case, the hydraulic rod 533 needs to be controlled to retract the movable frame 532 to allow passage.
