Description

Technical Field

[0001] This utility model relates to the technical field of corrugated cardboard production equipment, and in particular to an automatic glue separation mechanism. Background Technology

[0002] In a corrugated board production line, the gluing machine is a very important piece of equipment. The function of the gluing machine is to apply adhesive to the corrugated board to make it stronger, so that it can be better bonded together on the double-facer to form corrugated board.

[0003] Currently, the gluing process for corrugated cardboard is achieved through the combined use of gluing rollers and scraper rollers on a gluing machine. During the gluing process, glue overflows, causing glue to adhere to the edges of the corrugated cardboard. After the corrugated cardboard is formed, it needs to be trimmed. Taking a 2.5-meter wide production line as an example, a typical corrugated cardboard production line can produce about 250,000 to 400,000 square meters of cardboard per day. After forming a 2.5-meter wide cardboard, each side is trimmed by 10mm-20mm. If the edges of the corrugated cardboard are also glued when passing through the gluing machine, it is equivalent to wasting glue on 6,400 sheets of 2.5-meter cardboard per day, with a loss rate as high as 1.6%. This cost loss is very significant in corrugated cardboard production lines. Furthermore, because the cardboard edges are glued, the equipment will be covered with glue as it passes through the entire production line, causing stubborn glue stains. This requires manual removal of the cardboard, cleaning of the conveyor belts, machine downtime, etc., wasting labor and costs. Summary of the Invention

[0004] The purpose of this utility model is to overcome the above-mentioned defects in the prior art and provide an automatic glue separation mechanism, which greatly reduces glue waste caused by trimming and cutting the edges after cardboard forming.

[0028] The automatic adhesive separation mechanism in this embodiment, such as Figures 1 to 2 As shown, it includes: a support base 1, and displacement components 2 arranged facing each other on the left and right sides of the support base 1. The displacement components 2 include a ball screw 21 movably disposed on the support base 1.

A guide rod 23 connected to the movable seat 22 is also provided on the support base 1. A servo motor 24 is connected to the input end of the ball screw. In order to increase the output torque of the servo motor 24, a planetary reducer 25 is also provided between the ball screw 21 and the servo motor 24 in this embodiment. In addition, the displacement components 2 also include two sets of photoelectric limit sensors 3. The two sets of photoelectric limit sensors 3 are respectively disposed at the beginning and end of the stroke of the ball screw 21. At the same time, in order to facilitate the wiring of various electrical equipment, a wire groove square tube 11 is provided at the bottom of the support base 1.

[0029] Each displacement assembly 2 is connected to a set of adhesive separation modules 4. The adhesive separation module 4 includes a lifting assembly and an adhesive separation block 41 connected to the lifting assembly. The adhesive separation block 41 is provided with an insertion part 412 that can be inserted between the top glue roller 5 and the scraper roller 6. The cross-section of the insertion part 412 is triangular, as shown in the figure. The front and rear sides of the insertion part 412 are respectively provided with a first concave arc-shaped surface 413 and a second concave arc-shaped surface 414. The junction of the first concave arc-shaped surface 413 and the second concave arc-shaped surface 414 forms a sharp point. The left and right sides form a flat surface; the separator module 4 also includes a separator main seat 42 fixed to the movable seat 22, a first through hole 12 is provided on the lower side of the support seat 1, and an extension 421 is provided on the lower side of the separator main seat 42. The extension 421 passes through the first through hole 12 and is connected to the movable seat 22. The lifting component is provided on the separator main seat 42; the lifting component includes a connector 46 and a lifting cylinder 43 fixed to the separator main seat 42. One end of the connector 46 is connected to the lifting cylinder 43, and the other end of the connector 46 is connected to the separator block 41.

[0030] Furthermore, to enable the adhesive block 41 to be inserted more precisely between the glue roller 5 and the scraper roller 6, the lifting assembly of this embodiment also includes a fixing member 44, which is fixedly connected to the displacement assembly 2. The connecting member 46 is connected to the lifting cylinder 43 through a spherical bearing 45. The other end of the connecting member 46 away from the lifting cylinder 43 is connected to a rotating shaft 47. Specifically, the front end of the connecting member 46 is fixedly connected to the middle position of the rotating shaft 47 through a bolt 461. The two ends of the rotating shaft 47 are movably mounted on the fixing member 44. Specifically, a first sliding hole 441 matching the two ends of the rotating shaft 47 is provided on the front side of the fixing member 44, and the two ends of the rotating shaft 47 are sleeved in the first sliding hole 441.

[0031] The aforementioned separator module 4 also includes a connecting arm 411. One end of the connecting arm 411 is connected to the separator block 41, and the other end is connected to the fixing member 44. The connecting arm 411 is provided with a bending part 4111, which can better cooperate with the operation of the glue roller 5 and the scraper roller 6.

[0032] Brief description of the working principle of this utility model: The servo motor 24 and planetary reducer 25 of this utility model can be fixed on the base of the gluing machine. During use, the lifting cylinder 43 is activated, driving the rotating shaft 47 of the connecting piece 46 to form a lever structure. This improves the transmission force while making the overall structure more reliable and preventing left-right deviation. Figure 5As shown, under the combined action of the lifting cylinder and connecting piece 46, the adhesive block 41 assembly extends between the gluing roller 5 and the scraper roller 6. The first concave arc surface 413 and the second concave arc surface 414 are the same shape as the gluing roller 5 and the scraper roller 6, respectively, so that it can be closer to the gluing roller 5 and the scraper roller 6, further restricting the paper or corrugated paper. In order to adapt to paper of different widths, this embodiment is equipped with a displacement component 2 and a photoelectric limit sensor 3. Specifically, the paper or corrugated paper is detected by the photoelectric limit sensor 3 before entering the gluing roller 5 for gluing. The actual width of the paper is detected and the data is sent to the servo motor 24. The data detected by the light curtain is compared with the data of the encoder of the drive motor. The servo motor 24 drives the ball screw 21 to transmit torque. The ball screw 21 generates the power to move left and right by rotating, driving the moving seat 22 to slide left and right. Figure 5 As shown, the distance between the two gluing modules 4 can be adjusted. The moving seat 22 is then connected to the gluing main seat 42 by bolts. The gluing main seat 42 is connected to the connecting arm 411. Guided by the cylindrical guide rod 23, the gluing block 41 on the connecting arm 411 is powered to move left and right, so that the glue is the same width as or smaller than the width of the corrugated paper and does not spread or overflow, achieving the effect of no glue leakage. When the cardboard is formed and trimmed by the edge trimming machine, the waste paper generated by the trimming will not be wasted because of the glue attached. At the same time, this structure minimizes the unbalanced force and torque on the gluing plate during opening and closing. The gluing blocks 41 on both sides will not produce a figure-eight shape or non-parallel state, reducing the impact on the equipment and increasing the service life of the equipment.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
