Description

Technical Field

[0001] The utility model relates to the technical field of packing and packaging, in particular to a vertically driven side carton sealing machine. Background Art

[0002] At present, in packaging factories, in order to improve production efficiency, some mechanical equipment is used to replace manual packaging operations. Among them, the side carton sealing machine is a carton sealing and packaging equipment that automatically seals the upper and lower bottoms of the carton with roll-applied tape. Any self-adhesive tape can be used.

[0003] During the packaging process, most of the existing side carton sealing machines are unable to effectively limit the box body, which makes the box easily shift when moving, resulting in the misalignment of the adhesive strips, making it impossible to effectively pack the box. This type of packaging needs to be reworked and repacked, which affects the packaging efficiency.

[0004] To this end, we propose a top and bottom driven side carton sealing machine to solve the above problems. Utility Model Content

[0022] In the description of the present invention, it should be understood that terms such as "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are used solely to facilitate the description of the present invention and to simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-3, a top and bottom driven side sealing machine, including a roller conveyor 1 and a tape mechanism 4, the tape mechanism 4 is hoisted on the roller conveyor 1 through a top frame 3, and a telescopic member 5 is installed on the top frame 3 to drive the tape mechanism 4 to move up and down, the telescopic member 5 adopts one of a cylinder, a hydraulic cylinder or an electric push rod to drive the tape mechanism 4 to move up and down so that it can fit the upper surface of the box during packaging, thereby sealing the box with tape. A pair of side limit strips 2 are also installed on the roller conveyor 1, and the length direction of the side limit strips 2 is parallel to the conveying direction of the roller conveyor 1, which is used to limit the box. Taking into account the differences in the sizes of the boxes, the side limit strips 2 are set A slider 22 is installed below the roller conveyor 1 through a support rod 21, and the support rod 21 passes through the roller gap of the roller conveyor 1, and does not affect the transmission of the roller conveyor 1. The two sliders 22 pass through the double-headed screw 23 and the guide rod 24. The slider 22 is slidingly connected to the guide rod 24, and the two sliders 22 are symmetrically threaded on the two threaded sections of the double-headed screw 23. The double-headed screw 23 is rotatably installed below the roller conveyor 1 through the bearing seat. One end of the double-headed screw 23 is also connected to a motor 25. When the motor 25 drives the double-headed screw 23 to rotate, the two sliders 22 respectively drive the two side limit bars 2 to approach or move away from each other, so as to clamp or release the box.

[0026] Furthermore, a slide rod 7 is installed on the hanger 42, and a slide sleeve 8 for the slide rod 7 to slide through is installed on the top frame 3. The slide rod 7 slides inside the slide sleeve 8 to limit the telescopic part 5 to prevent the tape mechanism 4 from deflecting during lifting.

[0027] See also Figure 2-3 In order to facilitate the sticking of tape, a sticking mechanism 4 is provided, which includes a support frame 41, to which a hanger 42 is connected, and the top of the hanger 42 is connected to the output end of the telescopic member 5. Top limit strips 43 are symmetrically installed on both sides of the support frame 41 to press the top of the box. One end of the support frame 41 is rotatably installed with a support tube 411 for clamping the tape roll, and the other end of the support frame 41 is rotatably installed with a pair of parallel guide tubes 412, so that after the tape is unwound from the support tube 411, its back side passes under the pair of guide tubes 412, so that its sticky surface faces downward, so that it can be stuck on the box.

[0028] See also Figure 2-3 A number of guide rollers 6 are installed on the opposite side of the side limit strip 2 and below the top limit strip 43, and the axial direction of the guide roller 6 is parallel to the axial direction of the roller shaft of the roller conveyor 1, so that when the side limit strip 2 and the top limit strip 43 limit the box, they do not affect the movement of the box following the roller conveyor 1, and when the guide roller 6 rolls, the friction resistance to the box is small.

[0029] Furthermore, a locking bar 4111 is screwed onto the outer end of the support tube 411. When the locking bar 4111 is unscrewed, the tape roll on the support tube 411 can be replaced. When the locking bar 4111 is screwed on so that it is close to the end of the tape roll, the tape roll can be locked in so that it rotates synchronously with the support tube 411.

[0030] See also Figure 4-5 In order to facilitate cutting the tape, a heat sealing knife 413 is provided on the outer side of the guide cylinder 412 away from the support cylinder 411, and the heat sealing knife 413 is connected to the suspension rod 417. A positioning strip 414 is provided between the two guide cylinders 412. The lower surface of the positioning strip 414 is provided with a plurality of air holes, and the positioning strip 414 is connected to the air cylinder 415. The air holes are connected to the interior of the air cylinder 415. A piston rod 416 is movably installed in the air cylinder 415. A piston block is provided at the lower end of the piston rod 416 for sliding inside the air cylinder 415. The rod on the piston rod 416 and the opposite sides of the suspension rod 417 are evenly provided with a plurality of air holes. The gears 418 are meshed with each other and are connected to each other via a gear 418. The gear 418 is rotatably mounted on the support frame 41 via a bearing seat. A motor 419 is mounted on the shaft end of the gear 418. When the motor 419 drives the gear 418 to rotate, the suspension rod 417 and the piston rod 416 move up and down in opposite directions. When the suspension rod 417 descends, the tape can be cut. At this time, the piston rod 416 rises, driving the internal pressure of the air cylinder 415 end to decrease, so that a negative pressure is formed at the air hole of the positioning strip 414, so as to absorb the broken tape head and prevent the tape from falling off the guide tube 412.

[0031] Furthermore, a limiting sleeve 4171 is fixed to the side of the support frame 41, and the suspension rod 417 slides through the interior of the limiting sleeve 4171 to limit the suspension rod 417 and ensure the stability of the lifting of the suspension rod 417.
