Description

Technical Field

[0001] The present application relates to the technical field of packaging equipment, and in particular to an automatic packaging tape winding machine. Background Art

[0002] When using long cartons to pack products, in order to improve the firmness of the packaging, in addition to sticking wrapping tape along the opening direction of the carton, it is also necessary to wrap a circle of tape perpendicular to the opening direction at a certain distance. The above steps are mostly completed manually, but when the carton contains heavy products, manual sealing is inefficient and time-consuming and labor-intensive.

[0003] At the same time, the utility model patent with the public authorization announcement number CN220363510U in the prior art provides a fully automatic tape winding machine and processing equipment, including a housing, a feed streamline and a discharge streamline are connected in a straight line in the housing, a material setting mechanism is arranged on the periphery of the feed streamline / discharge streamline, a tape winding station is formed between the feed streamline and the discharge streamline, a reciprocating transverse movement mechanism is arranged at the bottom of the housing, a belt pulling mechanism, a belt pressing mechanism and a belt cutting mechanism are arranged in sequence on the reciprocating transverse movement mechanism, an annular turntable is set up on the outer ring of the tape winding station, a tape reel is mounted on the annular turntable, and the annular turntable is driven and connected by a rotating mechanism. When in use, the application requires the annular turntable to rotate in a directional manner, thereby driving the tape reel to rotate continuously around the carton to perform the tape winding action. Since the tape is unwound by the self-rotation of the circular turntable, the tape's travel path is also circular, but the cross-section of the carton is square. When wrapping the tape, the tape often has to be unwound for a long time before it can be attached to the outer surface of the carton. At this time, the circular turntable is required not to rotate too fast, otherwise the tensioned tape will easily deform. At the same time, the entire winding stroke of the tape is also long, affecting the sealing efficiency of the carton. Utility Model Content

[0025] See also Figure 1-5 The present application provides the following technical solutions: an automatic packaging tape winding machine, comprising a rectangular frame 1; a support frame 2 is provided at the lower end of the outer side surface of the rectangular frame 1, a rectangular track 11 is provided on the front side surface of the rectangular frame 1, a tape unwinding device 9 is slidably connected to the rectangular track 11, a tape roll 8 is fixed on the tape unwinding device 9, and a belt transmission device for controlling the tape unwinding device 9 to move along the rectangular track 11 is provided on the front side surface of the rectangular frame 1.

[0026] Specifically, the belt transmission device drives the tape unwinding device 9 to rotate along the rectangular track 11, thereby realizing the tape unwinding action, so that the tape can be quickly wound around the outer surface of the carton.

[0027] A top flattening mechanism is installed at the upper end of the front side surface of the rectangular frame 1, an extension seat 6 is installed at the front side surface of the support frame 2, a slide rail 5 and a telescopic cylinder 7 are installed on the upper surface of the extension seat 6, a moving plate 4 inclined forward is slidably connected to the slide rail 5, a cutting and pressing mechanism 3 is installed on the moving plate 4, and the telescopic end of the telescopic cylinder 7 is connected to the moving plate 4.

[0028] Specifically, the shrink cylinder 7 can drive the movable plate 4 to move left and right along the slide rail 5, and the cutting and pressing mechanism 3 installed on the movable plate 4 can press the tape tightly against the lower surface of the carton while moving left and right.

[0029] Furthermore, the lower surface of the support frame 2 is provided with at least one adjustable support seat 10 .

[0030] Specifically, the adjustable support seat 10 is composed of a screw rod and a base installed at the bottom of the screw rod, and the screw rod is threadedly connected to the support frame 2.

[0031] Furthermore, the belt transmission device includes four stepper motors 14 installed at the four corners of the front side of the rectangular frame 1, the output shafts of the four stepper motors 14 are connected to driving gears, the four driving gears are connected together through an internal tooth conveyor belt 15, the inner side of the internal tooth conveyor belt 15 is meshed with the driving gear, and the outer side of the internal tooth conveyor belt 15 is connected to the tape unwinding device 9.

[0032] Specifically, the four stepper motors 14 work synchronously to drive the driving gear to rotate, the driving gear drives the internal tooth conveyor belt 15 to rotate, and the internal tooth conveyor belt 15 drives the tape unwinding device 9 to perform a circular motion along the rectangular track 11 to complete the tape winding action.

[0033] More specifically, at least one of the four stepper motors 2 14 can be selected as a driving motor, and the other stepper motors 2 14 can be replaced by a rotating shaft, and the driving gear is installed on the rotating shaft and the output shaft of the driving motor.

[0035] Specifically, the mounting plate 91 is slidably connected to the rectangular track 11. When winding the tape, depending on the position of the mounting plate 91 on the rectangular track 11, the stepper motor 95 can drive the baffle 92 to rotate, and the baffle 92 drives the guide roller 93 to rotate, thereby preventing the tape from falling off the guide roller 93.

[0036] Furthermore, the top flattening mechanism includes two telescopic cylinders 13 symmetrically arranged front and back mounted on the rectangular frame 1 , and a top pressing plate 12 is mounted on the telescopic end of the telescopic cylinder 13 .

[0037] Specifically, after the product flows to the winding station, the two groups of top pressing plates 12 begin to descend under the drive of the telescopic cylinder 13 to fix the product, and then the ring gauge winding mechanism is activated to wrap the tape around the product for a specified number of circles, and finally the cutting and pressing mechanism is activated to cut the tape, and the roller conveys the product to the next winding position, and the winding mechanism repeats the above actions.

[0038] Furthermore, the cutting and pressing belt mechanism 3 includes a slide rail four 316, a telescopic cylinder five 315, a slide rail three 314, a telescopic cylinder six 317, a slide rail two 312 and a telescopic cylinder four 313 installed on the movable plate 4, wherein the slide rail four 316, the slide rail three 314 and the slide rail two 312 are laid on the upper surface of the movable plate 4 from left to right in sequence, and the slide rail four 316 is slidably connected with a slide table one 31, and an electric telescopic rod is installed on the slide table one 31, and a bottom pressure plate one 32 is installed at the end of the electric telescopic rod, and the slide table one 31 is connected to the telescopic end of the telescopic cylinder five 315.

[0039] Specifically, the telescopic cylinder 5 315 drives the slide 31 to slide upward by extending, and when the bottom pressure plate 32 slides to the bottom of the tape, the electric telescopic rod extends to press the bottom pressure plate 32 tightly against the tape.

[0040] Furthermore, a lifting bracket 34 is slidably connected to the slide rail three 314, and the lifting bracket 34 is connected to the telescopic end of the telescopic cylinder six 317. A bottom pressure plate two 33 is installed on the upper end surface of the lifting bracket 34, and a tape positioning roller 38 is provided at the edge of the lower surface of the bottom pressure plate two 33. An electric-controlled telescopic rod 36 is installed on the outer side surface of the lifting bracket 34. The telescopic end of the electric-controlled telescopic rod 36 is connected to an arc pressure plate 37 through a spring device. The arc pressure plate 37 is arranged directly below the tape positioning roller 38, and the telescopic end of the electric-controlled telescopic rod 36 is connected to a cutting knife 35.

[0041] Specifically, when cutting the tape, the electrically-controlled telescopic rod 36 is extended, and the arc-shaped pressing plate 37 arranged at the end of the electrically-controlled telescopic rod 36 presses the tape against the outer surface of the tape positioning roller 38. The electrically-controlled telescopic rod 36 continues to extend, and the spring device is compressed until the cutting knife 35 cuts the tape.

[0042] Furthermore, a slide 2 311 is slidably connected to the slide rail 2 312, and the slide 2 311 is connected to the telescopic end of the telescopic cylinder 4 313. The slide 2 311 is connected to the pressure roller 39 via the telescopic cylinder 3 310 arranged on its outer side.

[0043] Specifically, the telescopic cylinder 4 313 can push the slide 2 311 to slide upward along the slide rail 2 312 by extending. When the pressure roller 39 is located directly below the tape, the telescopic cylinder 310 extends to press the pressure roller 39 tightly against the tape. As the pressure roller 39 moves left and right, the tape can be firmly adhered.

[0044] During use: after the carton is transferred to the winding station, the two groups of top pressure plates 12 begin to descend under the drive of the telescopic cylinder 13 to fix the product. When the tape is wound, the end of the tape is located between the arc pressure plate 37 and the tape positioning roller 38. The arc pressure plate 37 presses the end of the tape tightly against the tape positioning roller 38. First, the telescopic mechanism drives the bottom pressure plate 32 to move upward, and the bottom pressure plate 32 presses the tape to the bottom of the carton. Then, the telescopic cylinder 7 extends and pushes the cutting and pressing mechanism 3 to move right as a whole, until the end of the tape is separated from between the arc pressure plate 37 and the tape positioning roller 38, and is pressed to the bottom of the carton by the bottom pressure plate 32. Then, the cutting and pressing mechanism 3 moves downward as a whole.

[0045] The belt transmission device drives the tape unwinding device 9 to rotate around the carton for one circle, and the tape is also wound around the carton for one circle. When the tape unwinding device 9 moves to the lower section of the rectangular track 11, the telescopic cylinder 6 317 extends to press the bottom pressure plate 2 33 tightly against the lower surface of the carton, and the synchronous electric-controlled telescopic rod 36 contracts to drive the arc pressure plate 37 and the cutting knife 35 to move downward. When the tape passes around the lower surface of the tape positioning roller 38, the tape has completed one circle of winding, and the tape can be cut next.

[0046] When the tape is cut, the electrically controlled telescopic rod 36 is first extended to drive the arc pressure plate 37 and the cutting knife 35 to move upward. The arc pressure plate 37 will first press the tape tightly against the outer surface of the tape positioning roller 38, and the electrically controlled telescopic rod 36 continues to extend until the cutting knife 35 presses the tape against the lower surface of the bottom pressure plate 33 and then cuts it.

[0047] Then, telescopic cylinder three 310 pushes out the pressure roller 39, so that the pressure roller 39 is pressed tightly against the pasted tape, and telescopic cylinder one 7 drives the pressure roller 39 to move to the left to achieve the pressing action of the tape end, and then the roller transports the carton to the next winding position, and the winding mechanism repeats the above actions.

[0048] It is worth noting that the input ends of the electrically-controlled telescopic rod 36, telescopic cylinder three 310, telescopic cylinder four 313, telescopic cylinder five 315, telescopic cylinder six 317, telescopic cylinder one 7, stepper motor one 95, telescopic cylinder two 13 and stepper motor two 14 are all electrically connected to the output end of the external power supply through an external control switch group.
