Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of packaging machinery, in particular to a water-based tape sticking machine core structure. BACKGROUND

[0002] In the existing carton sealing equipment, the main material for sealing tape is BOPP (biaxially oriented polypropylene) and PVC (polyvinyl chloride). However, these materials have the problem of not being easy to degrade, causing great pollution to the environment. In addition, in the process of paper box recycling and remanufacturing, manual tearing of the tape is required, significantly increasing labor costs. Therefore, with the deepening of the concept of environmental protection, traditional plastic packaging materials are gradually being eliminated, especially in developed countries, this trend is more obvious.

[0003] To address this challenge, those skilled in the art have developed a water-active tape (referred to as water-based tape) based on the concept of environmental protection. The tape uses degradable materials (such as water-based kraft paper tape), which can automatically generate adhesion when exposed to water, so that only water is needed to achieve adhesion during the packaging process, greatly simplifying the sealing operation and improving the convenience of paper box recycling.

[0004] For example, Chinese patent publication No. CN115743775A discloses a water-based tape automatic carton sealing machine core, the core structure of which includes a core frame, a paper disc for storing tape, a tape conveying mechanism for conveying tape, a cutting mechanism for cutting tape, and a liquid immersion mechanism fixed on the core frame. The liquid immersion mechanism is arranged between the cutting mechanism and the tape outlet end, and includes a liquid storage container and a movable adhesive roller. The adhesive roller is partially immersed in the liquid storage container, and through contact with the adhesive roller during tape conveying, one side of the tape is uniformly stained with liquid, thereby achieving water activation of the tape.

[0005] The above-mentioned scheme realizes automatic paper feeding, tape water brushing, tape cutting, and adhesive pasting and flattening, effectively promoting the development of environmentally friendly carton packaging, and conforms to the green packaging concept of sustainable development. However, the prior art still has the following shortcomings:

[0006] The existing water-based kraft paper tape includes various types of structures, such as ribbed water-based tape or non-ribbed water-based tape. Among them, ribbed water-based tape is an ideal choice for carton sealing due to its structural stability, which is not prone to edge curling or lifting during tape running. However, due to cost and technical barriers, most downstream enterprises still prefer to use non-ribbed water-based tape. However, the existing carton sealing machine core still has problems such as edge curling and lifting when processing non-ribbed water-based tape, affecting the carton sealing effect and sealing quality.

[0007] In view of the above, the present inventors have specially designed a water-based tape sticking machine core structure, which has thus been produced. UTILITY MODEL CONTENT

[0044] AsFigure 4 As shown, in the embodiment, the upper driving wheel 30 and the lower driving wheel 20 are respectively installed on the upper and lower sides of the moving knife 52, and the upper driving wheel 30 and the lower driving wheel 20 are on the same vertical plane and rotate in parallel, and the rotation shafts of the upper driving wheel 30 and the lower driving wheel 20 are hinged between the first panel 13 and the bottom plate 11 through the bearing member 21.

[0045] Preferably, the indentation rib 571 is provided with three, and is uniformly and symmetrically distributed along the axial direction of the auxiliary pressing wheel 40, and the indentation rib 571 is annular and is arranged along the outer peripheral surface of the auxiliary pressing wheel 40.

[0046] In the embodiment, the indentation rib 571 is distributed on both sides of the contact wheel 57, and the maximum interval is limited by the width of the water-based adhesive tape 100, and is located within the width range of the water-based adhesive tape 100, so that two indentation structures corresponding to the shape of the indentation rib 571 can be pressed on both sides of the water-based adhesive tape 100, so that the water-based adhesive tape 100 can be kept in the best flat state.

[0047] Preferably, as shown in Figure 4 , the first arc-shaped guide corner 572 is provided on both sides of the auxiliary pressing wheel 40 in the axial direction, and the second arc-shaped guide corner 221 is symmetrically provided on both sides of the opening of the indentation groove 22 away from the lower driving wheel 20.

[0049] As shown in Figure 3 , 5 , the liquid immersion assembly 60 is opposite to the upper driving wheel 30 and includes a liquid storage groove 61 and a water-dipping roller 62 opposite to the upper driving wheel 30 and used for transferring water in the liquid storage groove 61 to the roller surface, and the liquid immersion assembly 60 is slidingly arranged on the support 10 in the direction of approaching or moving away from the upper driving wheel 30.

[0050] Specifically, as shown in Figure 3 , 4 , 5, the liquid immersion assembly 60 is slidingly connected to the support 10 through a pneumatic cylinder device or a lead screw device, which is used to realize the approach or movement away from the upper driving wheel 30 to press or release the adhesive tape, and in the embodiment, the second driving pneumatic cylinder 63 is used for driving, and the second driving pneumatic cylinder 63 is a sliding seat 64 type pneumatic cylinder, and the side wall of the liquid storage groove 61 is locked and fixed on the sliding seat 64 of the second driving pneumatic cylinder 63, so that the opening of the liquid storage groove 61 faces upward and can move in the direction of approaching or moving away from the upper driving wheel 30 under the extension and retraction of the sliding seat 64 of the second driving pneumatic cylinder 63.

[0051] In this embodiment, the side of the liquid storage tank 61 near the upper drive wheel 30 is recessed downwards so that its sidewall forms a lateral opening 611 facing the upper drive wheel 30. The water-dipping roller 62 is rotatably connected to the sidewalls on both sides of the lateral opening 611, and the lowest position of the water-dipping roller 62 is lower than the bottom of the lateral opening 611 and extends to a position close to the bottom of the liquid storage tank 61. The outer peripheral side of the water-dipping roller 62 extends to a position protruding from the lateral opening 611 so that it forms a contact position that extends beyond the liquid storage tank 61. When the second drive cylinder 63 extends, the liquid storage tank 61 can drive the wet roller 62 to move to the position of contact with the wheel surface of the upper drive wheel 30. At this time, the upper drive wheel 30 is exactly at the contact position of the wet roller 62, realizing the contact between the wet roller 62 and the upper drive wheel 30. When the wet roller 62 rotates, the liquid in the liquid storage tank 61 can be transferred along its roller surface to the surface of the water-based adhesive tape 100 at the contact position, activating the water-based adhesive tape 100 to make it sticky, thereby facilitating the subsequent sealing of the carton.

[0052] Preferred, such as Figure 5 As shown, the liquid storage tank 61 is provided with anti-roll plates 66 distributed above the wet roller 62 and parallel to the conveyor channel 70. Several anti-roll strips 661 extend from the lower end of the anti-roll plates 66. Several annular relief grooves 621 are arranged around the roller surface of the wet roller 62.

[0053] Preferably, the smoothing part 31 is a closed ring and is arranged around the outer peripheral surface of the upper drive wheel 30. In this embodiment, the smoothing part 31 contacts the surface of the wet roller 62. Through its flat ring surface, the water-based tape 100 is further smoothed so that it remains flat and passes through the opening of the tape channel 70, which facilitates the subsequent sealing process.

[0054] Preferred, such as Figure 4 , 5 As shown, a transition piece 80 is provided on one side of the conveyor channel 70 and between the upper drive wheel 30 and the lower drive wheel 20. The transition piece 80 has a flat surface parallel to the direction of the conveyor channel 70.

[0055] Preferably, the transition member 80 is L-shaped and includes a fixed edge 81 and a sheet-like body 82 perpendicularly connected to the fixed edge 81.

[0056] Preferably, a number of hollowed-out grooves 83 are formed through the sheet-like main body 82.

[0057] Therefore, by the sheet-shaped body 82, the water-based adhesive tape 100 can be stopped and guided to move smoothly along the tape running channel 70, and the setting of the hollow groove 83 can reduce the friction between the sheet-shaped body 82 and the water-based adhesive tape 100, further increasing the smoothness of the tape running.

[0058] Preferably, as shown in the drawings, Figure 4 As shown, the gap position between the tape running channels 70 is provided with a waterproof adhesive tape 100 winding prevention rod 90.

[0059] In this embodiment, the winding prevention rod 90 is L-shaped, and the inner side is locked and fixed to the bottom plate 11 of the support 10, and the other end is vertically extended away from the bottom plate 11 to form a parallel relationship with the tape running channel 70. The winding prevention rod 90 is used to block the gap position between the tape running channels 70 to prevent the water-based adhesive tape 100 from winding into the gap during transmission, such as the gap between the sheet-shaped body 82 and the lower driving wheel 20.

[0060] The upper driving wheel 30 and the lower driving wheel 20 are respectively driven to rotate by the stepping motor 23 or the servo motor. In this embodiment, the upper driving wheel 30 and the lower driving wheel 20 are respectively driven to rotate by two stepping motors 23. The two stepping motors 23 are installed in the first mounting area 14. The output shaft of the stepping motor 23 extends to the back of the bottom plate 11 through the bottom plate 11. The rotating shaft of the upper driving wheel 30 and the lower driving wheel 20 also extends to the back of the bottom plate 11 through the bottom plate 11. The rotating shaft and the corresponding output shaft are connected by a synchronous belt mechanism (not shown in the figure). Therefore, by the double driving wheel and the stepping motor 23 driving mode, the feeding length of the water-based adhesive tape 100 can be accurately controlled, effectively avoiding the problem of too short or too long adhesive tape, thereby significantly improving the quality and efficiency of carton packaging.

[0061] The beneficial effects of the utility model are as follows:

[0062] The utility model discloses a mutually matched indentation rib 571 and indentation groove 22 are arranged between the lower driving wheel 20 and the auxiliary compression wheel 40 on both sides of the tape running channel 70 entrance position, and the surface of the water-based adhesive tape 100 is actively indented, which effectively prevents the edge curling or lifting problem of the non-rib water-based adhesive tape 100 during transmission, and also ensures that the adhesive tape maintains the best flat state during the whole packaging process. At the same time, the ring piece-shaped smoothing part 31 on the upper driving wheel 30 at the outlet of the tape running channel 70 further enhances the flatness of the adhesive tape, making the final sealing box effect more beautiful and firm, so that the core structure of the adhesive tape machine is adapted to the non-rib water-based adhesive tape 100 which is low in cost but prone to edge curling problem, greatly widening the application scene of the equipment and reducing the use cost of enterprises.

[0063] The utility model has been described exemplarily above in combination with the drawings, obviously, the utility model specific implementation is not limited by the above-mentioned mode, as long as various non-essential improvements of method concept and technical scheme of adopting the utility model or the utility model concept and technical scheme are directly applied to other occasions without improvement, all are within the protection scope of the utility model.
