Description

Technical Field

[0001] The utility model belongs to the field of labeling machines, and particularly relates to a packaging box labeling machine. Background Art

[0002] After the hypochlorous acid disinfectant solution is prepared, it is filled into the packaging boxes one by one by a filling machine, and then a certain number of filled packaging boxes are loaded into the packaging boxes for sealing. Then, a labeling machine is used to label the packaging boxes, and finally the packaging boxes are stacked and stored in the warehouse.

[0003] When the existing labeling machine labels, the label is separated from the labeling roll paper under the action of the label tearing board, and the separated label directly falls onto the packaging box. The label is leveled by a leveling plate installed behind the label tearing board, so as to prevent the label from falling off the packaging box. Although the whole labeling action can be completed well in this way, the label is prone to wrinkles and it cannot be ensured that each label can closely adhere to the packaging box, resulting in poor labeling quality. Summary of the Utility Model

[0004] In view of the above problems, the purpose of the utility model is to provide a packaging box labeling machine, aiming to solve the problem of poor labeling quality of the existing packaging box labeling machine.

[0005] The utility model adopts the following technical scheme:

[0006] The packaging box labeling machine includes a carrier frame, on which a unwinding wheel, a guiding component, a label tearing component, a reversing wheel, a pre-pressing component, and a rotatable winding wheel are sequentially arranged. The label tearing component includes a sliding plate installed on the carrier frame. A label tearing board and an adjusting roller are respectively arranged above and below the sliding plate. The label tearing board is fixedly installed and the adjusting roller is rotatably installed. A sliding cylinder is arranged on the carrier frame, and the driving shaft of the sliding cylinder is connected to the sliding plate. A labeling mechanism is arranged on the carrier frame opposite to the end of the label tearing board. The labeling mechanism includes a lifting cylinder, on which a labeling cylinder slides. The driving shaft of the lifting cylinder is connected to the labeling cylinder through a connecting block. A bottom plate is arranged on the driving shaft of the labeling cylinder. The labeling mechanism further includes an adsorption plate, on which a limiting groove is opened, and the bottom plate is located in the limiting groove. A locking nut penetrates through the bottom of the adsorption plate and is screwed into the bottom plate.

[0007] Further, the guiding component includes a fixed frame, the top surface of the fixed frame is a carrier plate. The carrier frame is sequentially provided with a guiding rod and a pressing cylinder towards the carrier plate. The driving shaft of the pressing cylinder is provided with a lower pressing plate. A limiting plate is arranged on the guiding rod, and a limiting groove opening is opened at the bottom of the limiting plate.

[0008] Furthermore, sliding grooves are formed in both the carrier board and the label tearing board. A pair of locking blocks are slidably arranged in the sliding grooves. Guide plates are arranged on both sides of the sliding grooves. Guide grooves are formed in the inner sides of the guide plates. Guide nuts are inserted into the guide plates, and the bottoms of the guide nuts are screwed into the locking blocks on the same side for locking.

[0009] Furthermore, the pre-pressing assembly includes an upper pre-pressing roller and a rotating frame rotatably installed in the fixing frame. A lower pre-pressing roller is rotatably arranged on the rotating frame. A pre-pressing screw is screwed upward from the bottom of the fixing frame, and the top of the pre-pressing screw supports the rotating frame.

[0010] Furthermore, the shaft rods of the upper pre-pressing roller and the winding wheel both penetrate through the carrier frame and are respectively provided with double-layer rotating wheels and belt pulleys.

[0018] In order to make the purpose, technical solution and advantages of the present utility model patent clearer and more understandable, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] In order to illustrate the technical solution described in the present utility model, the following is illustrated by specific embodiments.

[0020] For the convenience of description, only the parts related to the embodiments of the present utility model are shown.

[0021] Combined with Figures 1-5 As shown, the labeler for packaging boxes includes a carrier 1, on which a unwinding wheel 2, a guiding assembly, a label tearing assembly, a reversing wheel 4, a pre-pressing assembly, and a rotatable winding wheel 5 are sequentially arranged. The label tearing assembly includes a slide plate 6 installed on the carrier 1. Above and below the slide plate 6, a label tearing plate 7 and an adjusting roller 8 are respectively arranged. The label tearing plate 7 is fixedly installed and the adjusting roller 8 is rotatably installed. A sliding cylinder 9 is arranged on the carrier 1, and the driving shaft of the sliding cylinder 9 is connected to the slide plate 6. A labeling mechanism is arranged on the carrier 1 opposite to the end of the label tearing plate 7. The labeling mechanism includes a lifting cylinder 10, on which a labeling cylinder 11 is slidably arranged. The driving shaft of the lifting cylinder 10 is connected to the labeling cylinder 11 through a connecting block 12. A bottom plate 13 is arranged on the driving shaft of the labeling cylinder 11. The labeling mechanism further includes an adsorption plate 14. As Figure 6 , a limiting groove 15 is formed in the adsorption plate 14, and the bottom plate 13 is located in the limiting groove 15. A locking nut (blocked in the figure) penetrates into the bottom of the adsorption plate, and the locking nut is screwed into the bottom plate.

[0022] After the hypochlorous acid disinfectant solution is produced, it is filled into filling bottles by a filling machine, and then a certain number of filled filling bottles are put into a packaging box for sealing. Then, a labeler is used to label the packaging box. Finally, the packaging boxes are stacked and stored in a warehouse.

[0023] In actual situations, the labeler is arranged opposite to the conveying table. Before labeling, the label roll paper needs to be installed on the unwinding wheel according to requirements, and the front end of the label roll paper needs to pass through the guiding assembly, the label tearing assembly, the reversing wheel, and the pre-pressing assembly in sequence according to requirements, and finally be installed on the winding wheel.

[0024] After the packing box is conveyed to the labeling position of the labeling machine, the lifting cylinder drives the adsorption plate to move downward. After the adsorption plate adsorbs the label, at this time, the sliding cylinder drives the sliding plate to slide backward a short distance to form an avoidance interval. The driving shaft of the labeling cylinder drives the adsorption plate to move downward, and the adsorption plate directly presses the label against the corresponding position of the packing box. The labeling cylinder drives the adsorption plate to reset, and the sliding cylinder drives the sliding plate to reset, waiting to stick the next label on the next packing box.

[0025] In this structure, the adsorption plate 14 has an inner cavity, and a plurality of adsorption holes 141 are opened at the bottom of the adsorption plate, and the adsorption holes are communicated with the inner cavity. A vacuum connection hole 142 communicated with the inner cavity is opened on the side plate of the adsorption plate. The vacuum connection hole is connected to the adsorption machine through a hose. Since the adsorption machine is not the key content of this device, it will not be described in detail here.

[0026] The adsorption plate is installed on the bottom plate. When installing the adsorption plate on the bottom plate, first stick the adsorption plate to the bottom plate as required. The bottom plate is located in the limiting groove. The staff holds the adsorption plate, then passes the locking nut through the bottom of the adsorption plate, and then turns the locking nut until the locking nut is screwed into the bottom plate and locked. The whole installation process is also relatively simple.

[0027] In this device, as Figure 5 , the guiding assembly includes a fixed frame 16, the top surface of the fixed frame 16 is a carrier plate 17, a guiding rod 18 and a pressing cylinder 19 are sequentially arranged on the carrier 1 towards the carrier plate, a lower pressing plate 20 is arranged on the driving shaft of the pressing cylinder 19, a limiting plate 21 is arranged on the guiding rod 18, and a limiting groove opening 22 is opened at the bottom of the limiting plate 21.

[0028] In addition, as a preferred structure, sliding grooves 23 are opened on both the carrier plate 17 and the label tearing plate 7, a pair of locking blocks 24 are slidably arranged in the sliding grooves 23, guiding plates 25 are arranged on both sides of the sliding grooves 23, guiding grooves 26 are opened on the inner sides of the guiding plates 25, guiding nuts are penetrated through the guiding plates 25, and the bottoms of the guiding nuts are screwed into the locking blocks on the same side and locked.

[0029] During the actual installation process of the labeling roll paper, first loosen all the guiding nuts, then adjust the distance between the front and rear pairs of guiding plates according to the width of the labeling roll paper, then pass the front end of the labeling roll paper through the limiting groove opening, the front and rear pairs of guiding plates in sequence, and then pass through the reversing wheel and the pre-pressing assembly in sequence, and finally fix it on the winding wheel. Finally, move the two guiding plates of the same pair towards the labeling roll paper respectively until both ends of the labeling roll paper are located in the guiding grooves on the same side, and then tighten all the guiding nuts. It should be noted that during the process of moving the guiding plates, the locking blocks move synchronously in the sliding grooves.

[0030] Before the labeling machine performs the label tearing action, the pressing cylinder drives the lower pressing plate to move downward. A slit is formed between the lower pressing plate and the carrier plate, and the labeling roll paper passes through the slit. Both the lower pressing plate and the limiting notch play a role in limiting the labeling roll paper up and down, while the guiding plate plays a role in limiting the left and right sides of the labeling roll paper. This makes the labeling roll paper more stable during the labeling process and the label tearing effect better.

[0031] Furthermore, as a preferred structure, as Figure 5 , the pre-pressing assembly includes an upper pre-pressing roller 27 and a rotating frame 28 rotatably installed in the fixing frame 16. A lower pre-pressing roller 29 is rotatably provided on the rotating frame 28. A pre-pressing screw 291 is screwed upward from the bottom of the fixing frame 16, and the top of the pre-pressing screw 291 supports the rotating frame 28.

[0032] When the front end of the labeling roll paper passes through the pre-pressing assembly, first loosen the pre-pressing screw. The pre-pressing screw moves downward for a certain distance, and the rotating frame rotates downward. At this time, the lower pre-pressing roller moves away from the upper pre-pressing roller and forms an opening. The front end of the labeling roll paper passes through the opening and is fixed to the winding wheel. Finally, tighten the pre-pressing screw again. The pre-pressing screw moves upward and pushes the lower pre-pressing roller to press the labeling roll paper tightly. Under the action of the pre-pressing assembly, the winding wheel is more stable and reliable when winding the labeling roll paper.

[0033] In this structure, as Figure 3 , the shaft rods of the upper pre-pressing roller 27 and the winding wheel 5 both pass through the carrier frame and are respectively provided with double-layer rotating wheels 30 and belt pulleys 31. A driving motor 32 is also provided on the carrier frame 1. A driving wheel 33 is provided on the driving shaft of the driving motor 32. A matching belt 34 is provided between the driving wheel 33 and one of the rotating wheels of the double-layer rotating wheel 30, and between the other rotating wheel of the double-layer rotating wheel 30 and the belt pulley 31.

[0034] When the winding wheel performs the winding action on the labeling roll paper, the driving motor drives the double-layer rotating wheel to rotate. Driven by the two belts, the upper pre-pressing roller and the winding wheel are driven synchronously. Thus, the winding wheel completes the winding action.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the invention shall be included in the protection scope of the present invention.
