Description

Technical Field

[0001] This application relates to the field of paper bag machine technology, specifically an integrated detachable glue applicator. Background Technology

[0002] During the production process of paper bag machines, glue needs to be applied to designated positions on the target paper so that the corresponding paper surfaces can be folded and glued together to form the bag body in subsequent forming processes. After the machine stops, in order to prevent the glue from drying, the glue residue in the glue application device needs to be cleaned. Since the existing glue application devices are fixedly installed on the wall panel, during the cleaning process, glue and cleaning fluid are always spilled onto the wall panel, transmission mechanism and other adjacent parts. On the one hand, this contaminates the equipment, and on the other hand, glue may adhere to areas where it is not needed, causing damage to the paper bags or jamming of the equipment. Therefore, it is necessary to improve the system. Summary of the Invention

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] Please see Figures 1 to 4 The integrated detachable glue application device includes a wall panel 2, a main shaft 9, a support beam 3, a housing 1, a guide rail 4, a half shaft 7, a rubber wheel 6, a locking component, a bearing seat 8, and a glue scraper 12, wherein:

[0030] The main shaft 9 is rotatably mounted on the wall plate 2 and located on the conveying path of the target paper, perpendicular to the conveying direction of the target paper. Here, the main shaft 9 can be mounted on the wall plate 2 using existing structures such as bearing seats.

[0031] The support beam 3 has at least two parallel and spaced beams fixedly installed on the outside of the wall panel 2, and the longitudinal direction of the support beam 3 is parallel to the axis of the main shaft 9;

[0032] The top of the box 1 is open and placed on the support beam 3 to hold the glue;

[0033] The guide rail 4 is fixedly installed at the bottom of the housing 1 and slides with the inner side of the support beam 3 to guide the axial displacement of the housing 1 relative to the main shaft 9.

[0034] The half-shaft 7 is rotatably mounted on the housing 1, and the half-shaft 7 is parallel to the support beam 3;

[0035] The rubber wheel 6 is mounted on the half shaft 7 and housed inside the housing 1, with the highest arc of the outer circle of the rubber wheel 6 protruding from the upper surface of the housing 1.

[0036] The main shaft 9 extends axially towards one end of the housing 1 to form a connecting shaft segment 901. The cross-section of the connecting shaft segment 901 is non-circular. Here, the non-circular shape can be square, rhombus, hexagon, oval, etc. Preferably, in this embodiment, the cross-section of the connecting shaft segment 901 is square.

[0037] The half-shaft 7 extends out of the housing 1 and is axially recessed to form a guide cavity 701 for accommodating the sliding connecting shaft section 901. It can be understood that the cross-sectional shape of the guide cavity 701 is consistent with the cross-sectional shape of the connecting shaft section 901.

[0038] The locking element is located on the outside of the support beam 3. After the connecting shaft section 901 engages with the guide cavity 701, it is used to lock the housing 1 onto the guide rail 4. In this embodiment, the locking element is a locking screw 5. Specifically, after the housing 1 is installed on the support beam 3, the guide rail 4 is securely connected to the support beam 3 by tightening the locking screw 5, thereby fixing the housing 1 onto the support beam 3, ensuring the stable operation of the housing 1 and other components installed on it, and allowing for quick disassembly.

[0039] According to the structure provided in this embodiment, the integrated detachable glue applicator provided in this application uses a half-shaft 7 set in the housing 1 to install the glue-bearing wheel 6, and simultaneously uses a plug-in connection with the main shaft 9 to detachably drive the glue-bearing wheel 6 to work; a support beam 3 is designed to install and support the housing 1, and the guide rail 4 at the bottom of the housing 1 is used for guidance during disassembly and assembly, which facilitates the separation of the housing 1, the glue-bearing wheel 6, the half-shaft 7 and the guide plate 11 from the main shaft 9 and removal of the whole assembly to a special cleaning station for cleaning. The structure is simple and effectively prevents the environment and other parts from being contaminated.

[0040] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The integrated detachable glue application device also includes a bearing housing 8 and a glue scraper 12, wherein:

[0041] The bearing housing 8 is fixedly installed on the housing 1 and is used to provide a sealed slewing bearing for the half shaft 7. The specific method of sealing the slewing bearing can adopt existing technology. The scraper 12 is installed inside the housing 1 and is located on the rising edge of the outer circle of the glue-carrying wheel 6 according to the rotation direction of the glue-carrying wheel 6. In this embodiment, the installation method of the scraper 12 can adopt existing technology. The scraper 12 has a scraper groove 1201 formed on it. The scraper groove 1201 extends radially into the glue-carrying wheel 6 and is used to scrape off the glue adhering to the side of the glue-carrying wheel 6 and leave a preset thickness of glue on the outer circle surface of the glue-carrying wheel 6. The scraped glue falls back into the housing 1. In this way, the glue in the housing 1 is not leaked, and the glue adhering to the outer circle surface of the glue-carrying wheel 6 is accurately measured to ensure the glue coating thickness and thus improve the bonding quality of the paper bag.

[0042] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 A through hole 201 is formed on the wall panel 2. At least one part of the connection area between the connecting shaft section 901 and the guide cavity 701 is located inside the through hole 201. It is understood that the inner diameter of the through hole 201 and the outer diameter of the half shaft 7 located in the guide cavity 701 are clearance fit. On the one hand, the rotation of the half shaft 7 is not affected, and on the other hand, the connection position is located inside the wall panel 2, which further improves safety.

[0043] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The integrated detachable glue applicator also includes a guide plate 11 located on the upper surface of the housing 1. The guide plate 11 is detachably mounted on the housing 1 by fasteners. The guide plate 11 has a cutout that exposes at least a section of the outer circular surface of the glue roller 6. The guide plate 11 is used to guide the part of the target paper to be glued into the glue application area of ​​the glue roller 6. In this way, as the target paper is conveyed forward by the bag making machine conveyor, the paper surface to be glued can be smoothly guided to the top of the glue roller 6 by the guide plate 11, and the glue in the housing 2 is transferred to the target paper through the outer surface of the glue roller 6. At the same time, the paper surface on both sides of the glue application area is supported during the glue application process to prevent the paper surface from sagging and ensure the glue application quality.

[0044] According to the structure provided in this embodiment, in this embodiment, the half shaft 7, the rubber wheel 6, the bearing seat 8, and the guide plate 11 are all integrated and installed on the housing 1 to form an integrated structure, which makes it easy to remove the whole assembly to clean the glue residue, avoid the glue from drying and solidifying inside the housing 1, and ensure normal subsequent use.

[0045] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 The integrated detachable glue applicator also includes a motor 10 located at the other end of the main shaft 9 for driving the main shaft 9. In this way, the power source is located on the outside of the other wall panel 2, which is far away from the housing 1, ensuring safety and convenience when disassembling and assembling the housing 1.

[0046] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 4 A guide cone 902 is formed at the front end of the connecting shaft segment 901. The cross-section of the guide cone 902 is similar to that of the connecting shaft segment 901, and the guide cone 902 has a set torsion angle along the axis of the connecting shaft segment 901. In this embodiment, the torsion angle is 3-8 degrees, preferably 5 degrees.

[0047] According to the structure provided in this embodiment, a guide cone 902 is formed at the front end of the connecting shaft section 901 of the main shaft 9. During installation, it can quickly and automatically align with the guide cavity 701, enabling rapid assembly and disassembly. The principle is as follows: when the housing 1 is placed on the support beam 3 and pushed towards the main shaft 9, since the small end of the guide cone 902 is smaller than the opening of the guide cavity 701, when the opening of the guide cavity 701 covers the guide cone 902, manually reciprocating the small-angle rotation of the rubber wheel 6 will cause the guide cone 902 to automatically adjust and match with the corresponding mating surfaces on the guide cavity 701 due to its spiral torsion structure. This guides the connecting shaft section 901 to smoothly enter the guide cavity 701 for rapid installation. After installation, glue is injected into the housing 1 for normal use. It is understood that in this embodiment, a handle (not shown) can also be installed on the outside of the housing 1 for easy loading and unloading of the housing 1.
