Description

Technical Field

[0001] The invention relates to a lamp tube package, and more particularly to a lamp tube paper sleeve and a manufacturing method thereof. Background Art

[0002] Lamp tube paper covers are often used for the transportation of lamp tubes and act as a buffer during the transportation process. The paper covers are made of cardboard and wrapping paper bonded together. The cardboard can be single-sided corrugated paper. The paper cover is in the shape of a long strip as a whole and has a U-shaped cross-section, with wrapping paper on the outside and corrugated paper on the inside. The inside of the paper cover is used to accommodate the lamp tube, and openings are provided at both ends of the paper cover that are connected to the inside of the paper cover.

[0011] S3 passes through a drying mechanism, a drying stage, and a paper roll;

[0012] S4 During the unwinding stage, both sides of the paper roll are glued by gluing mechanism 2;

[0013] S5 drives the waste newspaper pieces to be glued to the two sides of the paper roll of stage 1 through the feeding mechanism on both sides of the paper roll, thereby forming the paper roll of stage 2;

[0014] S6 dries the second paper roll through a drying mechanism;

[0015] S7 cuts the paper roll of stage 2 transversely into paper roll segments of stage 3;

[0018] By adopting the above technical solution, waste newspaper pieces can be electrostatically adsorbed through the electrostatic generator and the electrostatic electret discharge rod. The storage trough is used to store waste newspaper pieces on the one hand, and guide the movement of waste newspaper pieces on the other hand, so that the waste newspaper pieces on the top surface of the stacked waste newspaper pieces can contact the two sides of the paper roll after gluing, and the other waste newspaper pieces can return to their original positions.

[0019] The present invention is further configured as follows: the feeding mechanism comprises a second storage trough and an air jet assembly, the second storage trough is used for placing waste newspaper pieces and the edges of the waste newspaper pieces abut against the inner wall of the second storage trough, the air jet assembly comprises an air pump and a plurality of air nozzles, the air pump is connected to the air nozzles, a plurality of air ports for accommodating the openings of the air nozzles to be embedded are provided on the bottom surface of the second storage trough, and the air jet assembly drives the plurality of waste newspaper pieces to move upward by air jet until the top layer of waste newspaper pieces abuts against the bottom surface of the first paper roll.

[0020] By adopting the above technical solution, the stacked waste newspaper pieces are lifted up by the air pump and the air nozzle, so that the waste newspaper pieces on the top of the stacked waste newspaper pieces can contact the two sides of the stage one paper roll after gluing. The second storage trough is used for storing the waste newspaper pieces on the one hand, and guiding the movement of the waste newspaper pieces on the other hand.

[0021] The present invention is further configured as follows: the feeding mechanism includes an enclosure, a weighing assembly, a lifting assembly and a control host 1, the control host 1 is electrically connected to the weighing assembly and the lifting assembly, the lifting assembly includes a plurality of cylinders and a lifting plate, the bottom surface of the lifting plate is fixed to the output end of the cylinder, waste newspaper pieces are placed on the top surface of the lifting plate, the cylinder drives the lifting plate to move up until the top layer of waste newspaper pieces hits the bottom surface of the stage 1 paper roll, the outer edges of the waste newspaper pieces and the lifting plate both hit the inner edge of the enclosure, the weighing assembly includes a weighing platform, the weighing platform measures the weight of the lifting assembly and the waste newspaper pieces and transmits the data to the control host 1, and the control host 1 controls the lifting height of the lifting assembly according to the weight of the lifting assembly and the waste newspaper pieces.

The cardboard layer 2 is single-sided corrugated paper. The cardboard layer 2 and the color-printed packaging layer 3 are bonded. Waste newspaper pieces 4 arranged along the circumference of the inner wall are bonded to the inner walls at both ends of the sleeve body 1. The waste newspaper pieces 4 include a twisting portion located outside the sleeve body 1.

[0038] The manufacturing method thereof comprises the following steps:

[0042] S4 In the unwinding stage, both sides of the paper roll 20 are glued by the gluing mechanism 2 6;

[0043] S5: The waste newspaper pieces 4 are driven by the feeding mechanism on both sides of the paperboard roll to be bonded to both sides of the paper roll 20 of the stage 1, thereby forming the paper roll of the stage 2;

[0044] S6 dries the second paper roll through a drying mechanism;

[0045] S7 cuts the paper roll of stage 2 transversely into paper roll segments of stage 3;

[0046] In the S8 folding stage, three paper roll segments are glued end to end;

[0047] Among them, Figure 2 and Figure 3 As shown, the feeding mechanism includes a frame 5, a sliding bracket 7, a driving group, a control host 2, a plurality of storage troughs 9, two abutment plates 12 and an electrostatic adsorption component. The storage troughs 9 are arranged in an array on the sliding bracket 7 and are used to place waste newspaper pieces 4. The edges of the waste newspaper pieces 4 abut against the inner wall of the storage troughs 9. The electrostatic adsorption component includes an electrostatic generator 10 and an electrostatic electret discharge rod 11. The electrostatic electret discharge rod 11 is located above the stage 1 paper roll 20 and is used to adsorb the waste newspaper pieces 4 under the stage 1 paper roll 20. The sliding bracket 7 is slidably connected to the frame 5. Specifically, the frame 5 A plurality of slide rails are fixed with bolts, and a sliding bracket 7 is slidably connected to the slide rails. A weight sensor 21 electrically connected to the control host 2 is provided under the storage trough 9. The weight sensor 21 is used to measure the weight of the storage trough 9 and the waste newspaper pieces 4. The control host 2 starts the driving component 8 according to the data of the weight sensor 21.
