Description

Technical Field

[0001] The present application relates to the technical field of paper reel machinery, and in particular to an automatic glue spraying device for a rewinding machine. Background Art

[0002] A rewinder is a special equipment, mainly used for rewinding and slitting paper, mica tape, film and other materials. Its working principle is to slit wide rolls through the rewinder to make them reach the required width and specifications, providing convenience for subsequent processing or use; a rewinder is generally composed of a paper feeding part, a paper cutting part and a rewinding part; the paper feeding part is responsible for unwinding the base paper roll, the paper cutting part embosses and cuts the paper, and finally the rewinding part rewinds the cut paper into a finished paper roll.

[0003] The prior art discloses a rewinder, which includes an adjustable resistance feeding part, a deviation correction part, a paper tensioning roller, a paper cutting part, a paper clamping and paper loading part, a paper pressing part and a flipping part, which are arranged in sequence, and the above-mentioned parts are fixedly arranged on the wall panel in sequence; the structure of the flipping part is that it includes a motor C, a worm bearing seat and a worm wheel bearing seat installed on the transition wall panel, a worm assembly is installed on the worm bearing seat, and a worm wheel assembly is installed on the worm wheel bearing seat. The motor C is sequentially connected to the worm assembly, the worm wheel assembly and the support sleeve through a coupling sleeve, and the support sleeve is fixedly connected to the rotating shaft frame; the rotating shaft frame is provided with a motor E and a motor F, and the motor E and the motor F are respectively connected to a group of self-expanding shafts through their own pulleys.

[0004] With regard to the above-mentioned related technologies, when changing rolls, the delivered paper web is manually taped to the paper core. This method not only requires manual taping of the first roll, but also requires manual intervention for each sleeve change, which seriously reduces the work efficiency. In addition, each operation requires stopping the rewinder transmission system, and then requires a lot of manual operation. Once an operational error causes the paper web to loosen, it may cause the paper web to tear, and the paper must be re-tended, affecting the work efficiency of the rewinder. Summary of the invention

[0005] In order to achieve the connection between the paper core and the paper web when changing rolls while reducing manpower input and ensuring the working efficiency of the rewinder, the present application provides an automatic glue spraying device for the rewinder.

[0006] The automatic glue spraying device for a rewinding machine provided in the present application adopts the following technical solution: An automatic glue spraying device for a rewinding machine, comprising: A frame body, on which a base paper roller and two driving rollers are rotatably connected, the base paper roller and the driving rollers are axially aligned, and the two driving rollers form a supporting platform; Paper pressing frame, the paper pressing frame is slidably connected to the main body of the machine frame, the paper pressing frame slides in the vertical direction, and at least two paper pressing rods are rotatably connected to the paper pressing frame, and the paper pressing rods and the driving roller cooperate to form a driving cavity for placing the rewinding core; Hot melt glue gun, the hot melt glue gun is connected to the main body of the machine frame and is arranged towards the driving cavity, and the hot melt glue gun is arranged near the entrance end of the driving cavity, and the hot melt glue gun is connected with a glue supply machine; Paper separating unit, the paper separating unit is connected to the main body of the machine frame and is used for cutting the wide paper.

[0007] By adopting the above technical solutions, the rewinding core is fed into the driving cavity from one side of the main body of the machine frame, that is, the entrance end of the driving cavity. When the rewinding core passes under the hot melt glue gun, the glue supply machine conveys the melted glue into the hot melt glue gun through the glue delivery pipe. The hot melt glue gun sprays the glue onto the rewinding core, and then makes the rewinding core sprayed with glue slide axially along the driving roller to the place, and then starts the glue coating operation of the next rewinding core until all the rewinding cores are in place. The wide paper on the original paper roll is conveyed to one side of the rewinding core through the paper feeding unit, and the wide paper is cut into narrow papers corresponding to the width of the rewinding core through the paper separating unit. Then, the rewinding core is controlled on the supporting platform formed by the two driving rollers through the paper pressing frame. Then, the driving roller is controlled to rotate through an external driving structure. While the driving roller rotates, the rewinding core is driven to rotate through friction. The rotation of the rewinding core makes the narrow paper wind around it and adhere to the glue smeared on it; The designed automatic glue spraying device for the rewinding machine can install the original paper roll and the driving roller through the main body of the machine frame. The rewinding core can be supported and driven through the cooperation of the paper pressing frame and the driving roller. The automatic coating of glue on the rewinding core can be realized through the cooperation of the hot melt glue gun and the glue supply machine. Furthermore, on the premise of reducing labor input and ensuring the working efficiency of the rewinding machine, the connection between the paper core and the paper web can be realized during roll change. The wide paper on the original paper roll can be cut into multiple narrow papers with widths matching the rewinding core through the paper separating unit.

[0008] In a specific feasible implementation scheme, the original paper roll is located above the driving roller, and when the wide paper output from the original paper roll naturally droops, it is arranged close to one of the paper pressing rods.

The air pump can achieve the relative position static state of the arc-shaped counterweight disk and the rewinding core by pumping the gas in the adsorption holes. The walking component can realize the movement of the arc-shaped counterweight disk along the axial direction of the rewinding core, and then take out the swing control mechanism after multiple rewinding cores are in place.

The axial direction of the paper pressing rods 21 is the same as the axial direction of the driving rolls 12, and the paper pressing rods 21 and the driving rolls 12 cooperate to form a driving cavity for placing the rewinding core. In this application, the base paper roll 11, the driving rolls 12, and the paper pressing frame 2 are all externally connected with driving structures to achieve their movement purposes.

[0039] Referring to Figure 1 , in order to facilitate controlling the position of the wide-width paper output by the base paper roll 11, the base paper roll 11 is located above the driving rolls 12, and when the wide-width paper output from the base paper roll 11 naturally droops, it is arranged close to one of the paper pressing rods 21. In order to maintain this state, the base paper roll 11 can move horizontally. In order to better control the start and stop of the base paper roll 11 and the driving rods, the base paper roll 11 and the driving rolls 12 are both hollow, and a structural strengthening frame is welded and fixed inside the base paper roll 11 and the driving rolls 12 to ensure the structural strength of the base paper roll 11 and the driving rolls 12 on the premise of reducing the moment of inertia.

[0044] Refer to Figure 5, specifically, to drive the horizontal sliding rod 531, a driving motor 533 is bolted to the frame body 1. A driving gear 534 is coaxially key-connected to the output shaft of the driving motor 533. A plurality of tooth grooves adapted to the driving gear 534 are recessed on the horizontal sliding rod 531. The driving motor 533 rotates to drive the driving gear 534 to rotate, and the driving gear 534 meshes with the tooth grooves on the horizontal sliding rod 531 to realize the sliding of the horizontal sliding rod 531.

[0045] Refer to Figure 6 and Figure 7 , in some other embodiments of the present application, the swing control mechanism 53 includes an arc-shaped counterweight plate 535, an air pump 536, and two traveling components 537. The outer contour of the arc-shaped counterweight plate 535 is adapted to the inner cavity wall shape of the rewinding core, so that the outer wall of the arc-shaped counterweight plate 535 can fit with the inner cavity wall of the rewinding core. A plurality of adsorption holes 5351 are formed on the outer side wall of the arc-shaped counterweight plate 535. The air pump 536 is bolted to the arc-shaped counterweight plate 535, and the air pump 536 is communicated with the inner cavities of the plurality of adsorption holes 5351 through an air passage in the arc-shaped counterweight plate 535.

A through hole for the swing control mechanism 53 to pass through is formed on the frame body 1.

[0046] Refer to Figure 7 and Figure 8 , the traveling component 537 is connected to the arc-shaped counterweight plate 535 so that the arc-shaped counterweight plate 535 can move along the axial direction of the rewinding core. Specifically, the traveling component 537 includes a fixed strip 5371, a telescopic spring 5372, a traveling motor 5373, and a traveling wheel 5374.

The traveling wheel 5374 is coaxially key-connected to the output shaft of the traveling motor 5373, and the traveling wheel 5374 can be in rolling connection with the inner cavity wall of the rewinding core.

[0047] The implementation principle of an automatic glue spraying device for a rewinder in an embodiment of this application is as follows: A rewinding core is fed into the drive cavity from one side of the frame body 1, that is, the inlet end of the drive cavity. When the rewinding core passes under the hot melt glue gun 3, the glue supply machine conveys the melted glue to the hot melt glue gun 3 through a glue delivery pipe. The hot melt glue gun 3 sprays the glue onto the rewinding core, and then the rewinding core sprayed with glue slides axially along the drive roller 12 to the in-place position, and then the glue coating operation for the next rewinding core starts. This continues until all rewinding cores are in place. The wide-width paper on the base paper roller 11 is conveyed to one side of the rewinding core through the paper feeding unit, and the wide-width paper is cut into narrow-width papers corresponding to the width of the rewinding core by the paper splitting unit 4. Then, the rewinding core is controlled on the supporting platform formed by the two drive rollers 12 through the paper pressing frame 2. Then, an external drive structure is used to control the rotation of the drive roller 12. While the drive roller 12 rotates, the rewinding core is driven to rotate by friction. The rotation of the rewinding core causes the narrow-width paper to wind around it and adhere to the glue applied thereon. The base paper roller 11 and the drive roller 12 can be installed through the frame body 1. The rewinding core can be supported and driven through the cooperation of the paper pressing frame 2 and the drive roller 12. The automatic coating of glue on the rewinding core can be realized through the cooperation of the hot melt glue gun 3 and the glue supply machine. Thus, the connection between the paper core and the paper web can be achieved during roll change on the premise of reducing labor input and ensuring the working efficiency of the rewinder. The wide-width paper on the base paper roller 11 can be cut into multiple narrow-width papers with widths matching the rewinding core through the paper splitting unit 4.
