Description

Technical Field

[0001] The present invention relates to the technical field of box gluers, and in particular to a paper pressing mechanism of a box gluer and a use method thereof. Background Art

[0002] In the packaging industry's production process, the carton gluer is a key piece of equipment for forming cartons. The paper press, a crucial component of the machine, is responsible for efficiently pressing and conveying the glued cardboard. The glued cardboard requires the appropriate pressure applied by the paper press to ensure a tight fit and form a secure carton structure.

[0003] However, the existing paper pressing mechanism of the folder gluer still has some problems that need to be solved in practical applications.

[0004] On the one hand, different thicknesses of cardboard require different pressures when pressing together. Traditional paper pressing mechanisms typically use fixed pressure settings or simple pressure adjustment methods, making it difficult to accurately adjust the pressure according to changes in cardboard thickness. This can lead to loose pressing or plastic deformation due to excessive pressure, affecting the quality of the carton. In addition, the problem of plastic deformation can be further exacerbated by the poor design of the pressing mechanism when the cardboard enters the pressing mechanism.

[0005] On the other hand, after the paperboards are pressed together, some glue is squeezed out. If this glue is not dried quickly, it can easily cause the paperboards to stick together when stacked after discharge, affecting subsequent production and use. However, existing paper pressing mechanisms typically only focus on pressing and conveying functions, failing to incorporate drying and discharge steps. This increases process complexity and production time, thereby reducing production efficiency.

[0006] Therefore, a paper pressing mechanism of a box gluer and a method of using the same are proposed to solve the above problems. Summary of the Invention

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1: Figures 1 to 8 As shown, an embodiment of the present invention provides: a paper pressing mechanism of a box gluer, comprising a conveying mechanism 1, a conveying belt 2 is installed on the conveying mechanism 1, the conveying belt 2 is used to convey the glued cardboard, and a pressing mechanism 3 is installed on the conveying mechanism 1, the pressing mechanism 3 is used to press the glued cardboard; The conveying mechanism 1 is equipped with a tension adjustment mechanism 6, which is connected to the pressing mechanism 3 and is used to adjust the tension between the conveyor belt 2 and the pressing mechanism 3; The conveying mechanism 1 is provided with a drying mechanism 4, which is used to quickly dry the glue remaining on the cardboard after lamination. A discharge mechanism 5 is installed on the conveying mechanism 1 , and the conveying mechanism 1 drives the discharge mechanism 5 to operate. The discharge mechanism 5 is used to discharge the cardboard in the drying mechanism 4 .

[0030] Specifically, by setting a tension adjustment mechanism 6 on the conveying mechanism 1 and connecting it with the pressing mechanism 3, the tension between the conveyor belt 2 and the pressing mechanism 3 can be adjusted. At the same time, the pressing mechanism 3 is linked to achieve the effect of coordinated control of the tension force and pressing pressure of the conveyor belt 2, so that the paper pressing mechanism can accurately adjust the pressure according to the thickness of the cardboard, solving the problem of unstable bonding quality of the gluer.

[0031] By installing the drying mechanism 4 and the discharge mechanism 5 on the conveying mechanism 1, the drying mechanism 4 quickly dries the glue remaining on the cardboard after pressing, and the discharge mechanism 5 discharges the cardboard in the drying mechanism 4, thereby achieving the effect of integrated drying and discharge functions, and effectively solving the problem that the existing box gluer lacks a subsequent drying and discharge link, which causes the cardboard to stick easily and has low production efficiency.

[0032] Example 2: In order to realize the adjustment of the tension of the conveyor belt by the tension adjustment mechanism and the linkage with the pressing mechanism, as shown in FIG. Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment, the tension adjustment mechanism 6 includes an adjustment cylinder 61 and a connecting rod assembly 63. An adjustment roller 62 is mounted on the adjustment cylinder 61 via a second rotating member 611. The adjustment roller 62 passes through the inside of the conveyor belt 2 and is used to adjust the tension of the conveyor belt 2. The connecting rod assembly 63 is connected to the adjustment cylinder 61 via the second rotating member 611, connecting the tension adjustment mechanism 6 and the pressing mechanism 3.

[0033] The connecting rod assembly 63 includes a first connecting rod 631, which is rotatably mounted on a second connecting rod 633 via an adjustment bracket 632. A short rod 635 is mounted on the second connecting rod 633 via an elastic member 634. The short rod 635 is connected to the pressing mechanism 3. A second protective shell 64 is provided on the outside of the connecting rod assembly 63 to protect the connecting rod assembly 63.

[0034] This embodiment drives the adjusting roller 62 by adjusting the cylinder 61 to accurately change the tension of the conveyor belt 2, and uses the connecting rod assembly 63 to establish a linkage relationship between the tension adjustment mechanism 6 and the pressing mechanism 3, thereby solving the problem of independent adjustment of tension and pressing and difficulty in adapting to different cardboard thicknesses.

[0035] When the thickness of the cardboard changes, the adjusting cylinder 61 pushes the adjusting roller 62 to move up and down, and the first connecting rod 631 drives the second connecting rod 633 to swing through the adjusting frame 632. The elastic member 634 buffers the impact force during the adjustment process, ensuring that the short rod 635 smoothly drives the pressing mechanism 3 to adjust the height synchronously, so that the pressing pressure is dynamically matched with the tension of the conveyor belt 2.

[0036] For thick cardboard, the adjusting roller 62 moves up to loosen the conveyor belt 2, and the pressing mechanism 3 moves up simultaneously to avoid excessive squeezing; for thin cardboard, the adjusting roller 62 moves down to tension the conveyor belt 2, and the pressing mechanism 3 presses down simultaneously to ensure a tight fit.

[0037] This coordinated control mechanism significantly improves the quality of box gluing, avoiding cardboard deformation or loose bonding, and possesses outstanding substantive features. Furthermore, the protective design of the second protective shell 64 on the connecting rod assembly 63 prevents interference from external debris and component wear, thereby extending the service life of the mechanism.

[0038] Example 3: In order to dry the residual glue on the cardboard after lamination and discharge the dried cardboard, as shown in FIG. Figure 6 、 Figure 7 and Figure 8 As shown, in this embodiment, the drying mechanism 4 includes a fixed frame 41 and a drying box 42. The fixed frame 41 is equipped with a guide seat 411 for guiding the movement of the discharge mechanism 5 and connecting the drying box 42 and the conveying mechanism 1. The drying box 42 is equipped with a drying fan 43 for outputting a high-speed airflow to the drying box 42. The drying box 42 is provided with a push chute 421 for connecting the discharge mechanism 5 and the drying box 42, and a discharge chute 422 for discharging the cardboard in the drying box 42. A footrest 44 is provided at the bottom of the drying box 42 to stabilize the installation position of the drying box 42.

[0039] The discharge mechanism 5 includes a driving sprocket 53, which is connected to the conveying mechanism 1 and is connected to a driven sprocket 51 via a chain 52. The driven sprocket 51 is equipped with a reciprocating motion assembly 54 for discharging the cardboard in the drying box 42. A first protective shell 55 is provided on the outside of the driving sprocket 53 and the driven sprocket 51 to protect the driving sprocket 53 and the driven sprocket 51.

[0040] The reciprocating assembly 54 includes a rotating wheel 541, mounted on a carriage 543. A guide rod 542 and a connecting frame 544 are mounted on either side of the carriage 543. The guide rod 542 passes through the guide seat 411 and guides the movement of the connecting frame 544. A discharge push plate 56 is mounted on the connecting frame 544 and passes through the ejection chute 421 to discharge the cardboard from the drying box 42.

[0041] This embodiment integrates drying and discharging functions, solving the problem that traditional folder gluers lack subsequent processing links, resulting in cardboard adhesion and low production efficiency.

[0042] In the drying mechanism 4, the drying fan 43 outputs high-speed airflow to the drying box 42, which can quickly evaporate the moisture of the glue remaining at the cardboard pressing point, avoiding cardboard adhesion in subsequent processes; the foot support 44 ensures the stable installation of the drying box 42, and the guide seat 411 of the fixing frame 41 provides precise guidance for the discharge mechanism 5.

[0043] The discharge mechanism 5 drives the reciprocating motion component 54 through the transmission of the driving sprocket 53, the chain 52 and the driven sprocket 51. When the rotating wheel 541 rotates, the slide 543 moves along the guide rod 542, and the connecting frame 544 drives the discharge push plate 56 to reciprocate along the pushing trough 421, automatically pushing the dried cardboard out of the discharge trough 422.

[0044] During continuous production, after each cardboard sheet is dried, the discharge push plate 56 accurately pushes the cardboard out of the drying box 42 without manual intervention, achieving automated operation. The first protective shell 55 protects the sprocket assembly, preventing malfunctions caused by foreign objects being caught in the chain 52 during transmission.

[0045] Example 4: In order to realize the transmission of the conveyor belt by the conveying mechanism and the pressing of the paperboard by the pressing mechanism, Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, in this embodiment, the conveying mechanism 1 includes a base frame 11 and a top frame 12. The top frame 12 is fixedly mounted on the top of the base frame 11, and the bottom of the base frame 11 is flush with the bottom of the foot support 44. A first rotating member 111 is mounted on the base frame 11 for rotating the driven sprocket 51. An active roller 14 and a driven roller 13 are mounted on the top frame 12 for transmission of the conveyor belt 2. A driving motor 121 is mounted on the top frame 12 for driving the active roller 14 to rotate. A hole is opened on the top frame 12 and a sleeve 122 is installed in connection with the hole, which is used to guide the vertical movement of the pressing mechanism 3 and limit the downward movement distance of the pressing mechanism 3. A reserved groove 123 is opened on the top frame 12 for installing the connecting rod assembly 63. A rotating shaft 124 is mounted on the top frame 12 above the reserved groove 123 for rotating the adjustment frame 632.

[0046] The pressing mechanism 3 includes a mounting frame 31. The bottom of the mounting frame 31 passes through the sleeve 122 and is fixedly connected to the short rod 635. A guide roller 32, a first pressure roller 33, and a second pressure roller 34 are equidistantly mounted on the mounting frame 31. The axes of the guide roller 32, the first pressure roller 33, and the second pressure roller 34 are coplanar. The dimensions of the first and second pressure rollers 33, 34 match, and their outer walls contact the conveyor belt 2. The outer diameter of the guide roller 32 is smaller than that of the first and second pressure rollers 33, 34.

[0047] The structural design of the conveying mechanism 1 and the pressing mechanism 3 in this embodiment solves the problems of unstable conveying and inconvenient pressing adjustment.

[0048] In the conveying mechanism 1, the base frame 11 and the top frame 12 form a stable support, the driving motor 121 drives the active roller 14, and the driven roller 13 cooperates to ensure smooth transmission of the conveyor belt 2; the first rotating member 111 ensures smooth rotation of the driven sprocket 51, and the reserved groove 123 and the rotating shaft 124 provide an installation basis for the connecting rod assembly 63 to achieve linkage with the tensioning adjustment mechanism 6.

[0049] In the laminating mechanism 3, the mounting frame 31 moves vertically via the sleeve 122, ensuring precise guidance during the laminating process while also limiting the position of the sleeve 122 to prevent damage to the cardboard due to excessive downward pressure. The guide roller 32 guides the cardboard smoothly into the laminating area. The first and second pressure rollers 33 and 34 are matched in size and in contact with the conveyor belt 2, ensuring uniform pressure on the cardboard. During the conveying process, the guide roller 32 first guides the cardboard, and then the first and second pressure rollers 33 and 34 cooperate with the conveyor belt 2 to tightly press the coated cardboard together.
