A post-gluing mechanism and post-gluing machine

Abstract

The application relates to a gluing mechanism and a gluing machine, which comprises a rack, a roller rotatably connected to the rack, a coating area for material adhesion on the roller, and a polymerization structure arranged at least at one end of the roller. The polymerization structure comprises a polymerization piece closely arranged on the roller, and a polymerization surface formed on one side of the polymerization piece facing the center of the roller. The polymerization surface gradually extends from the side of the polymerization structure on the roller to the center of the roller along the rotation direction of the roller. The polymerization piece is arranged on the roller, so that when the part of the roller with residual glue passes through the polymerization surface, the polymerization surface drives the residual glue on the edge of the roller to the center of the roller along the extending direction of the polymerization surface. Therefore, after the glue is added on the roller and passes through the glue scraping plate, the excess glue on the roller will not be directly squeezed out from the edge of the roller.

Description

Technical Field

[0001] This application relates to the technical field of applying adhesive, specifically to an adhesive application mechanism and an adhesive bonding machine. Background Technology

[0002] The gluing mechanism is a mechanism that evenly applies glue to the surface of materials to bond them together. Currently, the main application method is to first evenly apply glue to a roller, and then roll the roller over the material to evenly coat the material with the glue applied to the roller.

[0003] In the prior art, the roller is fixed in position and rotates. There is a device for adding glue at a specific position near the roller. This device applies glue linearly to the roller along its length, meaning that all areas of the roller passing through this position will be coated with glue. At the same time, there is a scraper around the roller to scrape off excess glue, thereby controlling the thickness of the glue on the roller. Movable material is placed on the other side of the roller. When the material passes through the roller, it adheres to the roller, and glue is applied to the material. As the material moves, it becomes fully coated with glue.

[0004] After the roller applies glue to the material, some glue will still adhere to the roller. When the roller with the remaining glue is reapplied with glue, and the area with the reapplied glue passes by the glue scraper, some of the glue at the edge of the roller will be squeezed out by the glue scraper due to the excess glue. This not only wastes resources, but also makes it difficult to clean up the glue that falls on the ground. Utility Model Content

[0005] This application provides a gluing mechanism and a gluing machine to solve the problem of glue being squeezed out from the edge of the roller in related technologies.

[0006] In a first aspect, a gluing mechanism is provided, comprising: frame; A roller, rotatably connected to the frame, has a coating area on one side for material to adhere to the roller, and at least one end of the roller is provided with a polymer structure; The polymer structure includes a polymer component, which is disposed in close contact with the roller. The polymer component forms a polymer surface on one side facing the center of the roller, and the polymer surface gradually extends from the side of the roller where the polymer structure is disposed toward the center of the roller along the rotation direction of the roller. The roller passes through the coating area and then through the polymer component.

[0007] In some embodiments, the polymer surface extends beyond the center of the roller to the outside of the roller.

[0008] In some embodiments, the aggregate is connected to the frame.

[0009] In some embodiments, the frame is provided with a enclosure, the bottom of which is provided with a base plate. The enclosure and the base plate form a storage space for placing glue, and an opening is provided between the base plate and the enclosure.

[0010] In some embodiments, the side of the base plate facing the storage space is made of a thermally conductive material, and a heating element is provided inside the base plate.

[0011] In some embodiments, a scraper is provided on the side of the base plate facing the roller.

[0012] In some embodiments, a slider and a slide rail are also included, the slide rail being connected to the frame, the slider being connected to the enclosure, and the slider being slidably connected to the slide rail.

[0013] In some embodiments, a screw is further included, which is rotatably connected to the slide rail, passes through the slider, and engages with the slider.

[0014] In some embodiments, the frame is provided with a separation element; The separator is positioned close to the roller on one side. After any part of the roller passes through the coating area, it then passes through the separator and the polymerizing part in sequence.

[0015] Secondly, an adhesive bonding machine is provided, comprising: an adhesive bonding mechanism as described above; A transport mechanism for transporting materials to the coated area.

[0016] This application provides a gluing mechanism and a gluing machine. Because the application provides a polymer component on the roller, when the part of the roller with residual glue passes through the polymer surface, the polymer surface drives the residual glue on the edge of the roller towards the center of the roller along the direction of the polymer surface. Therefore, after the glue is added to the roller and passes through the scraper, the excess glue on the roller will not be squeezed directly from the edge of the roller. Attached Figure Description

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] This application provides a gluing mechanism and a gluing machine, which can solve the problem of glue being squeezed out from the edge of the roller in related technologies.

[0022] Please see Figures 1 to 6 A coating mechanism includes: a frame 1 and a roller 2, the roller 2 being rotatably connected to the frame 1. One side of the roller 2 has a coating area for material to adhere to the roller 2. At least one end of the roller 2 is provided with a polymerization structure 3, the polymerization structure 3 including a polymerization component 31, the polymerization component 31 being disposed close to the roller 2, the side of the polymerization component 31 facing the center of the roller 2 forming a polymerization surface 32, the side of the polymerization surface 32 that is in contact with the roller 2 being a polymerization edge 33, the polymerization surface 32 gradually extending from the side of the roller 2 where the polymerization structure 3 is provided towards the center of the roller 2 along the rotation direction of the roller 2, and when any part of the roller 2 passes through the coating area, it passes through the polymerization component 31; In this embodiment, the frame 1 is fixed in position, and the two ends of the roller 2 are rotatably connected to the frame 1. A motor is installed on the frame 1, and the output end of the motor is connected to one end of the roller 2 via a chain and sprocket. The motor drives the roller 2 to rotate, so that during the operation of this application, the roller 2 always rotates in one direction and continuously applies adhesive linearly along the length of the roller 2, so that the roller 2 is fully coated with adhesive. When the material passes through the coating area and adheres to the roller 2 via the conveying mechanism, there will be residual adhesive adhering to the roller 2. Polymerization structures 3 are respectively provided on both sides of the roller 2. When the part of the roller 2 with residual adhesive passes through the polymer edge 33, the polymer edge 33 is in close contact with the roller 2. As the outer wall extends, the remaining glue will gather from the edge of the roller 2 along the polymerization edge 33 towards the center of the roller 2. When the remaining glue gathers in the middle of the roller 2, and glue is applied to the roller 2 again, when it passes through the scraper 7, the newly applied glue and the remaining glue are mixed together, resulting in excess glue. This excess glue will be squeezed to both sides of the roller 2, but it will not be squeezed directly from the edges of the roller 2. Instead, due to the continuous rotation of the roller 2, it will cover the part that the roller 2 passes behind. And because the roller 2 is constantly rotating, the polymerization surface 32 and the polymerization edge 33 will continuously function. That is, during the operation of this application, the excess glue will accumulate in the scraping area, and there will be no situation where glue is squeezed out from the edge of the roller 2. It should be noted that as the remaining glue gathers along the polymerization edge 33 toward the center of the roller 2, the remaining glue will gradually accumulate on the polymerization surface 32, and the polymerization surface 32 will have the effect of driving away the remaining glue.

[0023] Furthermore, in this embodiment, the polymer surface 32 extends to the outside of the roller 2 at one end away from the middle of the roller 2. In order to better gather the remaining glue on both sides of the roller 2 towards the middle, it is necessary to ensure that the polymer edge 33 can cover all the remaining glue on both sides of the roller 2. That is, the end of the polymer surface 32 away from the middle of the roller 2 should be located on the roller 2, so that even the remaining glue at the very edge of the roller 2 will gather towards the center of the roller 2 along the polymer edge 33 to ensure a better effect.

[0024] Furthermore, in this embodiment, the polymer component 31 is connected to the frame 1. To facilitate automated production, the position of the roller 2 is fixed in this application. Only the position of the polymer surface 32 relative to the roller 2 needs to be fixed. This is achieved by connecting the polymer component 31 to the frame 1. The structure of the polymer component 31 in this application is as follows: Figure 5 As shown.

[0025] Specifically, in this embodiment, the frame 1 is provided with a surrounding component 4, and the bottom of the surrounding component 4 is provided with a base plate 5. The surrounding component 4 and the base plate 5 form a storage space for storing glue. An opening 6 is provided in the middle between the base plate 5 and the surrounding component 4. A scraper 7 is provided on the side of the base plate 5 facing the roller 2. The scraper 7 and the base plate 5 are an integral structure. When the roller 2 rotates, the operator can directly pour glue into the storage space. The glue will automatically flow out from the opening 6, pass through the scraper 7, and fall onto the roller 2. Because the glue itself is sticky, when the glue is between the scraper 7 and the roller 2, it will not break off and fall directly. When the glue adhering to the roller 2 passes through the scraper 7, the scraper 7 will intercept the excess glue, so that the thickness of the glue passing through the roller 2 is uniform. Traditionally, the glue is dripped onto the scraper 7. In this application, the storage component for storing glue and the scraper 7 are combined into one structure, that is, the scraper 7 and the base plate 5 are combined, which can greatly save the space occupied by the device.

[0026] More specifically, in this embodiment, the side of the base plate 5 facing the storage space is made of thermally conductive material, and a heating element is provided inside the base plate 5. The adhesive is divided into hot adhesive and cold adhesive. Cold adhesive can flow at room temperature, while hot adhesive cannot flow normally at room temperature. Therefore, when using hot adhesive, it is necessary to heat it. Thus, this application adds an electromagnetic heating device to the base plate 5. The electromagnetic heating device is prior art and will not be described in detail here. The hot adhesive in the storage space is heated by the electromagnetic heating device and the conduction of the thermally conductive material, so that the device is also suitable for hot adhesive.

[0027] Preferably, in this embodiment, it also includes a screw 10, a slider 8, and a slide rail 9. The slide rail 9 is connected to the frame 1, the slider 8 is connected to the enclosure, the slider 8 is slidably connected to the slide rail 9, the screw 10 is rotatably connected to the slide rail 9, the screw 10 passes through the slider 8, and the screw 10 cooperates with the slider 8. The slide rail 9 is fixedly connected to the frame 1 by bolts. The screw 10 passes through the part of the slider 8 located inside the slide rail 9. The rotation of the screw 10 controls the position of the slider 8 on the slide rail 9 through the thread. Due to different processes, different manufacturers need different thicknesses of glue on different rollers 2. This application sets the screw 10 to drive the slider 8 to move the enclosure, the base plate 5, and the scraper 7, so that the distance between the scraper 7 and the roller 2 changes, thereby adjusting the thickness of the glue on the roller 2.

[0028] As shown in the figure, in this embodiment, the frame 1 is provided with a separator 11. One side of the separator 11 is closely attached to the roller 2. When any part of the roller 2 is attached to the material and coated with glue, that part will first pass through the separator 11 and then rotate to the two aggregators 31. The two aggregators 31 gather the glue on the roller 2 towards the middle. The structure of the separator 11 is shown in the figure. Some materials are relatively light, such as pearl cloth. When such light materials are attached to the roller 2, the adhesive of the glue will cause the roller 2 to rotate. Therefore, after the material is coated with glue, it will pass through the separator 11 to separate the material from the roller 2 for subsequent processing and further processing in this application.

[0029] The working principle of this application is as follows: Before use, the distance between the scraper 7 and the roller 2 needs to be adjusted by rotating the screw 10 as needed. Then the roller 2 rotates and glue is poured into the storage space. The glue flows out from the opening 6 and is gradually and evenly coated on the roller 2. The material is sent from below to the bonding roller 2 for glue coating. The part of the roller 2 after being coated with glue rotates past the polymerization edge 33. Through the action of the polymerization plate, the glue on the edge of the roller 2 is driven towards the middle of the roller 2 to avoid the glue being squeezed out from the edge of the roller 2.
