Description

Technical Field

[0001] The present application relates to the technical field of gluing of packaging box parts, and in particular to an automatic gluing device for packaging box parts. Background Art

[0002] At present, packaging box parts refer to various parts of the packaging box, such as the top plate (cover plate), bottom plate, side plate, end plate, wrapping paper, etc. In the production process of packaging boxes, the gluing process of wrapping paper is one of the key links. The function of the gluing device is to evenly apply the glue on the wrapping paper so that subsequent folding, bonding and other processes can proceed smoothly. In the related art, the gluing device usually adopts a double roller structure for gluing. Specifically, the wrapping paper is fed between two oppositely arranged rollers through a conveying mechanism, and one side is fully coated with glue after extrusion. In order to continuously supply glue, a glue supply pipeline is generally arranged above the gluing mechanism, and the glue stored in the glue storage box is pumped to the roller space.

[0003] Regarding the above-mentioned related technologies: When the glue coating machine is shut down for a long time, the glue liquid in the glue supply pipeline is prone to solidification, resulting in blockage problems when the machine is started next time, or causing the glue liquid to bring out solid glue from the discharge port, which can easily lead to reduced glue coating quality. Summary of the invention

[0004] In order to reduce the possibility of reduced gluing quality, the present application provides an automatic gluing device for packaging box parts.

[0005] The present application provides an automatic gluing device for packaging box parts, which adopts the following technical solution: An automatic gluing device for packaging box parts, comprising: The gluing mechanism comprises a gluing roller group and a bracket, wherein the gluing roller group is arranged on the bracket and is used for gluing the packaging paper; The glue supply mechanism includes a glue storage component and a heating component. The glue storage component is arranged on the bracket. The glue storage component is connected to a glue supply hose. One end of the glue supply hose away from the glue storage component extends to above the glue coating roller group. The glue supply hose is used to supply glue to the glue coating roller group. The heating component is respectively connected to the glue storage component and the glue supply hose. The heating component is used to heat the glue storage component and the glue supply hose.

[0006] By adopting the above technical solution, the glue storage box in the glue storage assembly stores enough glue liquid, and the glue liquid is stably transported to the glue supply pipe above the glue coating roller group through the glue delivery pump, so that the glue liquid is transported to the glue coating roller group through the glue supply pipe, so that the glue coating roller group can evenly apply the glue liquid on the packaging paper, effectively improving the glue coating quality and efficiency. And the heating component can heat the glue storage box and the glue supply pipe respectively to maintain the temperature of the glue liquid, which is conducive to preventing the glue liquid from solidifying after a long period of shutdown. This not only solves the blockage problem existing in the glue coating device, but also improves the reliability and stability of the entire glue coating process, and reduces the possibility of reduced glue coating quality to a certain extent.

[0007] Optionally, the glue storage assembly includes a glue storage box and a glue delivery pump, the glue storage box is arranged on the bracket, one end of the glue supply hose is connected to the glue storage box, the other end of the glue supply hose extends to above the glue coating roller group, the glue delivery pump is arranged on the glue supply hose, and the heating assembly includes a first heating element and a second heating element, the first heating element is arranged in the glue storage box, and the second heating element is arranged on the glue supply hose.

[0008] By adopting the above technical solution, the first heating element is installed inside the glue storage box to ensure that the stored glue maintains a suitable working temperature; the second heating element is set on the glue supply pipe to ensure the fluidity of the glue during the transportation process. In this way, when the equipment is restarted, the blockage problem caused by the solidification of the glue can be avoided, and the risk of solid glue being brought out is reduced, thereby improving the glue coating quality and production efficiency.

[0009] Optionally, a guide platform is provided on the bracket, the guide platform is located below the glue coating roller group, the glue storage box is located below the guide platform, and one end of the guide platform is tilted downward.

[0010] By adopting the above technical solution, one end of the guide table is tilted downward, which can effectively prevent unused glue from accumulating on the guide table, avoiding the solidification problem caused by the glue staying on the platform for a long time. At the same time, this design helps to guide the excess glue to flow smoothly into the glue storage box, reducing waste and keeping the working environment clean. In addition, since the glue storage box is located below the guide table, it further ensures that the glue can flow back smoothly, reducing the system maintenance cost and improving the overall operation efficiency of the equipment.

[0011] Optionally, a receiving groove is provided in the rubber supply hose along its own axial direction, and the second heating element is arranged in the receiving groove and is arranged in a spiral shape.

[0012] By adopting the above technical solution, a receiving groove along the axis of the rubber supply hose is provided inside, and a spiral second heating element is installed in the receiving groove. This design can not only effectively increase the heating area and improve the heating efficiency, but also ensure that the temperature distribution of the glue liquid in the entire rubber supply hose is more uniform. This helps to prevent the glue liquid from solidifying due to local temperature unevenness, thereby avoiding the problem of blockage or the problem of solid glue liquid being brought out during the glue coating process, and improving the glue coating quality and equipment operation stability.

[0013] Optionally, the glue coating roller group includes a rotating drive member and two glue coating rollers, the two glue coating rollers are respectively rotatably connected to the bracket, the two glue coating rollers are parallel to and in contact with each other, the end of the glue supply hose away from the glue storage assembly extends to between the two glue coating rollers, the rotating drive member is arranged on the bracket, the rotating drive member is respectively connected to the two glue coating rollers, and the rotating drive member is used to drive the two glue coating rollers to rotate synchronously.

[0014] By adopting the above technical scheme, when it is necessary to glue the packaging paper, the packaging paper is first transported to the bottom of the two glue coating rollers. At the same time, the rotating drive member drives the two glue coating rollers to rotate synchronously, and the glue supply hose transports the glue to between the two glue coating rollers, so that the glue is coated on the two glue coating rollers as the two glue coating rollers rotate. This makes it easy to use the two glue coating rollers to evenly coat the glue on the packaging paper when the packaging paper passes through the two glue coating rollers, which helps to avoid quality problems caused by uneven glue coating.

[0015] Optionally, the glue coating roller includes a first roller body, a second roller body and a plurality of third roller bodies, the first roller body, the plurality of third roller bodies and the second roller body are rotatably connected in sequence, one end of the first roller body away from the third roller body is rotatably connected to the bracket and connected to the rotating driving member, one end of the second roller body away from the third roller body is rotatably connected to the bracket, an adjustment component is movably provided on the bracket, the adjustment component is movably connected to the first roller body, the second roller body and the third roller body, respectively, the adjustment component can make the first roller body drive the third roller body and the second roller body to rotate, or make the first roller body rotate alone.

[0016] By adopting the above technical solution, when it is necessary to glue small-sized packaging paper, the adjustment component cooperates with the rotary drive member to control the first roller to rotate alone, so that the first roller can be used to glue the packaging paper alone, which is conducive to reducing the possibility of glue being applied to the circumference of the second roller and the third roller, resulting in glue waste. And when it is necessary to glue large-sized packaging paper, the adjustment component cooperates with the rotary drive member so that the first roller can drive the third roller and the second roller to rotate synchronously, so as to glue the large-sized packaging paper. This design allows the gluing device to flexibly adjust the gluing method according to actual needs, so as to reduce glue waste and improve gluing efficiency and quality.

[0017] Optionally, the first roller body, the second roller body and the third roller body are respectively provided with through grooves along their own axial directions, and the cross-section of the through grooves is non-circular. The adjustment assembly includes a first adjusting rod and a second adjusting rod, the first adjusting rod and the second adjusting rod are relatively arranged and respectively slidably inserted into the through grooves, the first adjusting rod is slidingly connected to the first roller body, and the second adjusting rod is slidingly connected to the second roller body and the third roller body respectively, and the first adjusting rod can push the second adjusting rod to move in a direction away from the first roller body.

[0018] By adopting the above technical solution, when it is necessary to replace packaging paper of different specifications, the position of the second adjusting rod can be changed by pushing the first adjusting rod, so that the first roller can drive the corresponding number of second rollers to rotate synchronously through the first adjusting rod, so as to facilitate gluing the packaging paper of corresponding specifications. At the same time, the second adjusting rod can limit the second roller that is not in contact with the first adjusting rod to prevent the rotating second roller from driving the non-rotating second roller to rotate, which is conducive to reducing the waste of glue. This design not only improves the flexibility and adaptability of the equipment, but also ensures the stability and consistency during the gluing process.

[0019] Optionally, the adjustment component includes a telescopic driving member and a reset member, the reset member and the telescopic driving member are respectively arranged on the bracket, the reset member is connected to the second adjustment rod, the telescopic driving member is rotatably connected to the first adjustment rod, and the telescopic driving member is used to drive the first adjustment rod to move in a direction close to the second roller body.

[0020] By adopting the above technical solution, the telescopic drive member can accurately control the position change of the first adjustment rod, thereby pushing the second adjustment rod to move away from the first roller body. This design allows the connection relationship between the first roller body, the third roller body and the second roller body to be flexibly adjusted. At the same time, the reset member can quickly restore the position of the second adjustment rod when necessary, ensuring the stability and reliability of the entire system under different working conditions, so that the glue coating device can adapt to packaging paper of different specifications, effectively reducing the waste of glue liquid.

[0021] Optionally, the reset member includes a support sleeve and a reset spring arranged in the support sleeve, the support sleeve is arranged on the bracket and is slidably connected to the second adjusting rod, the reset spring is arranged in the support sleeve and is connected to the second adjusting rod, and the reset spring is used to push the second adjusting rod to move in a direction close to the first roller body.

[0022] By adopting the above technical solution, the support sleeve and the return spring can ensure that the second adjustment rod is always in the initial position when the telescopic drive is not working. When the telescopic drive drives the first adjustment rod to move in the direction close to the second roller body, the first adjustment rod will push the second adjustment rod to move away from the first roller body, so that the multiple rollers of the glue roller group rotate synchronously or independently to meet different glue coating requirements. When the roller position does not need to be adjusted, the return spring can quickly restore the second adjustment rod to its original position, ensuring the stability and reliability of the glue coating device and avoiding uneven glue coating or equipment failure caused by improper position of the adjustment rod.

[0023] Optionally, a protective ring is provided between the first roller body and the third roller body, between two adjacent third roller bodies, and between the second roller body and the third roller body.

[0024] By adopting the above technical solution, the setting of the protection ring can effectively prevent the wear and damage caused by the hard contact between the rollers during the gluing process. At the same time, the protection ring can also play a buffering role, reduce the impact force between the rollers, ensure a smoother gluing process, and improve the gluing quality and equipment service life.

The conveying mechanism 3 is used to convey the packaging paper to be glued and convey the glued packaging paper to the next process. The gluing mechanism 1 is arranged close to the conveying mechanism 3, and the gluing supply mechanism 2 is connected to the gluing mechanism 1. The gluing supply mechanism 2 is used to supply glue to the gluing mechanism 1, so that the gluing mechanism 1 can glue the packaging paper.

[0037] The conveying mechanism 3 includes a first conveying component 31 and a second conveying component 32. The first conveying component 31 and the second conveying component 32 are arranged at intervals, and the gluing mechanism 1 is arranged between the first conveying component 31 and the second conveying component 32. The first conveying component 31 is used to convey the packaging paper to be glued to the gluing mechanism 1, and the second conveying component 32 is used to receive the packaging paper that has been glued and convey the packaging paper to the next process.

[0038] It should be noted that, in the embodiment of the present application, the specific design of the first conveying component 31 and the second conveying component 32 is a conventional technical means for those skilled in the art, and therefore will not be elaborated in detail in the embodiment of the present application.

[0039] Reference Figure 1 The gluing mechanism 1 comprises a gluing roller group 11 and a bracket 12. The bracket 12 is arranged between the first conveying assembly 31 and the second conveying assembly 32, and the gluing roller group 11 is installed on the bracket 12 for gluing the packaging paper.

[0040] The glue roller group 11 includes a rotating drive member 111 and two glue rollers 112. The two glue rollers 112 are respectively rotatably connected to the bracket 12, and the two glue rollers 112 are parallel to and in contact with each other. The rotating drive member 111 is installed on the bracket 12, and the rotating drive member 111 is respectively connected to the two glue rollers 112. In this embodiment, the rotating drive member 111 adopts a structure of a motor and a synchronous belt to drive the two glue rollers 112 to rotate synchronously, so that the glue rollers 112 can be used to apply glue to the packaging paper.

[0041] Reference Figure 2 and Figure 3 The glue supply mechanism 2 includes a glue storage component 21 and a heating component 22. The glue storage component 21 is arranged on the bracket 12, and a glue supply pipe 23 is connected to the glue storage component 21. The glue supply pipe 23 extends from one end of the glue storage component 21 to between the two glue coating rollers 112 and is located above the two glue coating rollers 112, so that the glue supply pipe 23 is convenient for supplying glue to the two glue coating rollers 112.

[0042] The glue storage assembly 21 includes a glue storage box 211 and a glue delivery pump 212. The glue storage box 211 is mounted on the bracket 12, and glue liquid is stored in the glue storage box 211. One end of the glue supply pipe 23 is connected to the glue storage box 211. The glue delivery pump 212 is mounted on the glue supply pipe 23 and is responsible for delivering the glue liquid from the glue storage box 211 to between the two glue coating rollers 112.

[0043] Reference Figure 3 The heating assembly 22 includes a first heating element 221 and a second heating element 222. The first heating element 221 is installed inside the glue storage box 211. In this embodiment, the first heating element 221 is a heating tube, so that the first heating element 221 is used to heat the glue storage box 211 to maintain a suitable temperature in the glue storage box 211 and prevent the glue from thickening or solidifying due to low temperature.

[0044] A receiving groove 231 is provided in the glue supply tube 23 along its own axial direction, and the second heating element 222 is disposed in the receiving groove 231 and is disposed in a spiral shape. In this embodiment, the second heating element 222 is a heating wire, so that the glue supply tube 23 can be heated by the second heating element 222 to ensure that the glue liquid in the entire glue supply tube 23 can be evenly heated, further reducing the risk of solidification.

[0045] A guide platform 121 is installed on the bracket 12. The guide platform 121 is located below the two glue coating rollers 112, and one end of the guide platform 121 is tilted downward. A glue storage box 211 is located below the guide platform 121, and the top of the glue storage box 211 is open, so that the glue flowing down from the glue coating rollers 112 can fall onto the guide platform 121 and flow into the glue storage box 211 along the guide platform 121, so as to realize the recovery of the glue.

[0046] The implementation principle of the automatic gluing device for packaging box parts in the embodiment of the present application is as follows: when the packaging paper needs to be glued, the first conveying component 31 is first used to convey the packaging paper to be glued to the bottom of the two glue rollers 112, and the packaging paper is brought into contact with the second conveying component 32, so that the second conveying component 32 conveys the packaging paper to the next process. In this process, the glue pump 212 conveys the glue in the glue storage box 211 to between the two glue rollers 112 through the glue supply pipe 23, and at the same time, the rotating driving member 111 drives the two glue rollers 112 to rotate synchronously, so that the surfaces of the two glue rollers 112 are coated with glue, so that the glue is conveniently applied to the packaging paper using the two glue rollers 112 to complete the gluing operation.

[0047] Example 2 Reference Figure 4 The difference between this embodiment and embodiment 1 is that the glue coating roller 112 includes a first roller body 1121 , a second roller body 1122 and a plurality of third roller bodies 1123 .

[0048] Reference Figure 4 The first roller 1121, the third rollers 1123 and the second roller 1122 are rotatably connected in sequence, and one end of the first roller 1121 away from the third roller 1123 is rotatably connected to the bracket 12, and one end of the second roller 1122 away from the third roller 1123 is rotatably connected to the bracket 12.

[0049] The first roller 1121 is connected to the rotary drive member 111 so as to drive the first roller 1121 to rotate by the rotary drive member 111. The glue supplying tube 23 is arranged close to the first roller 1121 so as to supply glue to the first roller 1121 by the glue supplying tube 23.

[0050] A protective ring 1124 is rotatably connected between the first roller body 1121 and the third roller body 1123, and between the second roller body 1122 and the third roller body 1123, respectively, so as to effectively prevent wear and damage caused by hard contact between the roller bodies during the gluing process.

[0051] It should be noted that, in this embodiment, the third roller body 1123 is provided as one. In other embodiments, the third roller body 1123 may also be provided as two or three, the specific number of which may be adjusted according to actual needs, and when the third roller body 1123 is provided as two or more, a protective ring 1124 may also be provided between two adjacent third roller bodies 1123.

[0052] Reference Figure 5 and Figure 6The first roller body 1121, the second roller body 1122 and the third roller body 1123 are respectively provided with through grooves 1125 along their own axis directions, and the multiple through grooves 1125 are sequentially connected, and the cross section of each through groove 1125 is non-circular. In this embodiment, the cross section of the through groove 1125 is rectangular.

[0053] Reference Figure 4 and Figure 6 The bracket 12 is provided with an adjustment assembly 13, which includes a first adjustment rod 131, a second adjustment rod 132, a telescopic driving member 133 and a reset member 134. The first adjustment rod 131 and the second adjustment rod 132 are arranged relatively to each other and are respectively slidably inserted into the through slot 1125, and the first adjustment rod 131 is slidably connected to the first roller body 1121, and the second adjustment rod 132 is slidably connected to the second roller body 1122 and the third roller body 1123. In this embodiment, the shapes of the first adjustment rod 131 and the second adjustment rod 132 are adapted to the shape design of the through slot 1125.

[0054] The reset member 134 includes a support sleeve 1341 and a reset spring 1342 disposed in the support sleeve 1341. The support sleeve 1341 is fixed on the bracket 12 and is slidably connected to the second adjustment rod 132. The reset spring 1342 is disposed in the support sleeve 1341 and is connected to the second adjustment rod 132, and is used to push the second adjustment rod 132 to move in a direction close to the first roller body 1121.

[0055] The telescopic driving member 133 is fixed on the bracket 12 and is rotatably connected to the first adjusting rod 131. In this embodiment, the telescopic driving member 133 is a cylinder, so that the telescopic driving member 133 is used to drive the first adjusting rod 131 to move toward the direction close to the second roller body 1122.

[0056] The implementation principle of Example 2 is as follows: when it is necessary to glue a small-sized packaging paper, the first adjustment rod 131 is located in the first roller body 1121, and the second adjustment rod 132 is located in the second roller body 1122 and the third roller body 1123. At this time, the rotary drive member 111 works to drive the first roller body 1121 to rotate, and the second adjustment rod 132 limits the second roller body 1122 and the third roller body 1123, so that the second roller body 1122 and the third roller body 1123 do not rotate with the first roller body 1121. At the same time, the glue supply hose 23 transports the glue liquid to the first roller body 1121, so that the first roller body 1121 is used to glue the packaging paper.

[0057] During this process, part of the excess glue flows directly from the first roller 1121 to the guide platform 121 and flows back to the glue storage box 211, and the other part of the glue flows back to the glue storage box 211 along the second roller 1122 and the third roller 1123. Since the second roller 1122 and the third roller 1123 do not rotate, the glue will not be coated on the peripheral surfaces of the second roller 1122 and the third roller 1123 in large quantities, but will flow back to the glue storage box 211, thereby effectively reducing the possibility of excessive glue remaining on the peripheral surfaces of the second roller 1122 and the third roller 1123 and causing waste of glue, thereby helping to reduce production costs.

[0058] When it is necessary to glue a large-sized packaging paper, the telescopic driving member 133 works to drive the first adjusting rod 131 to move toward the direction close to the second roller body 1122, and the first adjusting rod 131 pushes the second adjusting rod 132 to move, so that the first adjusting rod 131 enters the through slot 1125 in the third roller body 1123, and the second adjusting rod 132 withdraws from the third roller body 1123, and at the same time, the second adjusting rod 132 pushes the return spring 1342 to compress. At this time, the first roller body 1121 can drive the third roller body 1123 to rotate through the first adjusting rod 131, and the second adjusting rod 132 can limit the rotation of the second roller body 1122, so that the large-sized packaging paper can be glued through the cooperation of the first roller body 1121 and the third roller body 1123.

[0059] In the embodiment of the present application, by finely adjusting the connection relationship between the glue coating rollers 112, it is ensured that the glue is evenly distributed on the packaging paper during the gluing process, so that no matter how the specifications of the packaging paper change, the ideal gluing effect can be achieved. At the same time, the waste of glue is reduced, and the gluing device can adapt to packaging papers of different specifications, thereby effectively reducing production costs.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
