Description

Technical Field

[0001] The utility model relates to the technical field of label production equipment, in particular to a paper closing device. Background Art

[0002] Most labels are printed materials used to identify product instructions, and most have adhesive backing. However, some labels are printed without adhesive, and are also called self-adhesive labels. Labels with adhesive are commonly known as "self-adhesive labels." During the label production process, after the old backing paper is used up, the leading end of the new backing paper needs to be glued together with the trailing end of the old backing paper to ensure continued label production. Conventional technology manually connects the leading end of the new backing paper with the trailing end of the old backing paper using adhesive tape. However, during this process, the tape may crinkle and distort when attached to the backing paper, affecting subsequent production. Summary of the Invention

[0033] The bottom plate assembly 1 is used to position the leading end and the trailing end of the two rolls of bottom paper respectively;

[0034] The paper pressing assembly 2 is used to fix the two rolls of bottom paper on the bottom plate assembly 1;

[0035] The paper-laying assembly 4 includes: a tape box 41, a glue-laying plate 42, a telescopic mechanism and a glue-cutting tool 43;

[0036] A tape roll is provided in the tape box 41, and the tape on the tape roll is spread flat on the glue spreading board 42 with the glue surface facing the base paper. The telescopic mechanism is used to drive the glue spreading board 42 to stick the tape to the connection between the two rolls of base paper. When the tape sticks the two rolls of base paper together, the telescopic mechanism contracts, causing the glue cutting tool 43 to cut off the two ends of the tape.

[0037] The bottom plate assembly 1 positions the leading and trailing ends of the two rolls of bottom paper, the paper pressing assembly 2 fixes the leading and trailing ends of the two rolls of bottom paper, and the tape is spread flat on the glue-laying board 42 with the adhesive surface of the tape facing the bottom paper. The telescopic mechanism drives the glue-laying board 42 to move, so that the tape connects the two rolls of bottom paper. After the tape contacts the bottom paper, the telescopic mechanism begins to shrink, and the glue cutting tool 43 cuts the tape from both ends of the glue-laying board 42, so that the tape neatly sticks the two rolls of bottom paper together to avoid the tape sticking crookedly and wrinkling, which affects subsequent production.

[0038] like Figures 1 to 3 As shown, the bottom plate assembly 1 includes: a paving plate 11, a paving roller 12 and a positioning plate 13;

[0039] The flattening rollers 12 are arranged on both sides of the material laying board 11, and the flattening rollers 12 are used to lay the base paper flat on the material laying board 11. The positioning plates 13 are arranged on the material laying board 11, and the positioning plates 13 are located on both sides of the base paper. The positioning plates 13 are used to position the base paper. A glue cutting groove is provided on the material laying board 11 corresponding to the glue cutting tool 43.

[0040] The bottom paper is guided through the upper surface of the spreading plate 11 by the spreading roller 12 so that the base is spread flat on the spreading plate 11 , and the bottom paper is clamped between the positioning plates 13 on both sides by the positioning plates 13 .

[0041] like Figures 1 to 5 As shown, the bottom plate assembly 1 further includes: a paper closing frame 14 .

[0042] The paper pressing assembly 2 and the paper closing assembly 4 are both arranged on the paper closing frame 14 .

[0043] The paper pressing assembly 2 includes two paper pressing cylinders 21 and a paper pressing board 22 .

[0044] The two paper pressing cylinders 21 are respectively arranged on both sides of the paper closing assembly 4, and the two paper pressing cylinders 21 are both arranged above the paper closing frame 14. The output ends of the two paper pressing cylinders 21 pass through the paper closing frame 14 to connect the paper pressing board 22. The paper pressing cylinders 21 drive the paper pressing board 22 to fix the bottom paper.

[0045] The two paper pressing cylinders 21 drive the two paper pressing boards 22 to move respectively, so that the two paper pressing boards 22 press the two rolls of bottom paper onto the paper closing frame 14 respectively, thereby fixing the two rolls of bottom paper.

[0046] like Figures 1 to 5 As shown, the telescopic mechanism includes: a telescopic cylinder 44, a telescopic base plate 45 and a telescopic column 46;

[0047] The telescopic cylinder 44 is provided on the paper-closing frame 14 , and the output end of the telescopic cylinder 44 passes through the paper-closing frame 14 and is connected to the telescopic bottom plate 45 . One end of the telescopic column 46 is connected to the telescopic bottom plate 45 , and the other end is connected to the glue-laying board 42 .

[0048] The telescopic cylinder 44 drives the telescopic bottom plate 45 to move, causing the rubber spreading board 42 to move downward, and the tape under the rubber spreading board 42 connects the two rolls of base paper. After the tape contacts the base paper, the telescopic column 46 begins to contract, causing the rubber cutting tool 43 to be inserted into the rubber cutting groove, and the tape is cut from both ends of the rubber spreading board 42.

[0049] like Figure 6 As shown, the telescopic column 46 includes: a base tube 461, a telescopic tube 462 and a telescopic spring 463;

[0050] The bottom tube 461 is arranged on the telescopic bottom plate 45 , one end of the telescopic tube 462 is sleeved in the bottom tube 461 and the other end is connected to the rubber plate 42 , and the telescopic spring 463 is arranged in the bottom tube 461 and the telescopic tube 462 .

[0051] The telescopic cylinder 462 slides in the bottom cylinder 461 to extend and retract. After the rubber cutting tool 43 cuts the tape from both ends of the rubber paving board 42, the telescopic cylinder 44 drives the telescopic bottom plate 45 to move upward, and the elastic force of the telescopic spring 463 resets the rubber paving board 42.

[0052] like Figure 7 As shown, the paper closing assembly 4 includes: a telescopic spring 47 and a tape clip 48;

[0053] The telescopic spring 47 is U-shaped and is arranged on the telescopic base plate 45. The groove width of the telescopic spring 47 is related to the width of the tape. The tape clamp 48 is arranged in the groove of the telescopic spring 47 and is used to fix one end of the tape.

[0054] The worker pulls the end of the tape and places the end of the tape in the groove of the telescopic spring 47 , and clamps the end of the tape with the tape clamp 48 . At this time, the tape is laid flat under the rubber plate 42 .

[0055] Above, refer to Figures 1 to 7 The utility model describes a paper-closing device according to an embodiment of the present invention. After an old roll of base paper is used up, the worker moves the leading end of the new base paper to the material laying board 11 and places the leading end of the base paper between the positioning plates 13 on both sides, and places the tail end of the old base paper and the leading end of the new base paper under the glue laying board 42. The worker pulls the end of the tape and places the end of the tape in the groove of the telescopic spring 47. The end of the tape is clamped and fixed by the tape clamp 48 so that the tape is laid flat under the glue laying board 42. The telescopic mechanism drives the glue laying board 42 to move so that the tape connects the two rolls of base paper. After the tape contacts the base paper, the telescopic mechanism begins to contract, and the glue cutting tool 43 cuts the tape from both ends of the glue laying board 42, so that the tape neatly sticks the two rolls of base paper together to avoid the tape from sticking crookedly and wrinkling, which affects subsequent production.
