[0036] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0037] like Figure 1 As shown, an embodiment of this application provides a glue-rolling mechanism 100 for applying adhesive to a material to be bonded. The glue-rolling mechanism 100 includes a base 1, a heating roller 2, an adhesive container 3, and a drive assembly 4.

[0038] The base 1 is used to support other components of the roller coating mechanism 100. Optionally, the base 1 includes two substrates 11 that are flush with each other.

[0039] The heating roller 2 is rotatably mounted on the base 1. For example, two substrates 11 are rotatably connected to both ends of the heating roller 2. The heating roller 2 heats the adhesive, preventing it from cooling and curing. The material to be bonded is placed below the heating roller 2, and the rotation of the heating roller 2 applies adhesive to the material. Optionally, the material to be bonded includes at least one of a bed core, sponge, latex pad, and felt.

[0040] like Figure 2 As shown, the glue container 3 is rotatably mounted on the base 1. The glue container 3 includes a container body 31 and a base plate 32. The container body 31 is rotatably mounted on the base 1. Optionally, the container body 31 is generally U-shaped, and the base plate 32 is located at the bottom end of the container body 31.

[0041] like Figure 3 and Figure 4 As shown, the rotation of the glue container 3 allows it to move closer to or further away from the heating roller 2. The first station is when the glue container 3 is away from the heating roller 2, and the second station is when it is close to the heating roller 2. In the second station, a glue trough is formed between the glue container 3 and the heating roller 2, and multiple glue flow gaps are formed at intervals at the bottom of the glue trough.

[0042] like Figure 5As shown, when the glue container 3 is in the second working position, the edge of the base plate 32 of the glue container 3 contacts the heating roller 2, forming a glue tank between the glue container 3 and the heating roller 2 to hold the glue. Multiple glue flow gaps are formed between the edge of the base plate 32 near the heating roller 2 and the heating roller 2. The glue in the glue tank can be applied to the material 200 to be bonded through the glue flow gaps. Due to the spacing of the multiple glue flow gaps, spaced glue application areas 210 are formed on the material 200 to be bonded.

[0043] like Figure 6 , Figure 7 and Figure 8 As shown, for example, the base plate 32 includes a first base plate 321 and a second base plate 322 arranged alternately. At a height, the second base plate 322 is located below the first base plate 321. When the base plate 32 contacts the heating roller 2, the first base plate 321 contacts the heating roller 2, while the second base plate 322 does not, forming a glue-flowing gap between the second base plate 322 and the heating roller 2. When the heating roller 2 rotates, the glue in the glue tank can be applied to the material to be bonded 200 through the glue-flowing gap, forming spaced glue-coating areas 210 on the material to be bonded 200.

[0044] The drive assembly 4 is disposed on the base 1. The drive assembly 4 is used to drive the adhesive container 3 to rotate, so that the adhesive container 3 rotates between the first station and the second station.

[0045] In this embodiment, the glue container 3 of the glue-rolling mechanism 100 is rotatable. When the glue container 3 is close to the heating roller 2, the edge of the base plate 32 contacts the heating roller 2. Multiple glue-flowing gaps are formed between a portion of the edge of the base plate 32 and the heating roller 2. The glue in the glue tank can be applied to the material to be bonded 200 at intervals through the glue-flowing gaps, thereby saving glue consumption and reducing production costs. Reducing the amount of glue used can avoid local accumulation of glue, which can cause local hardening of the adhesive material and improve the quality of the adhesive material.

[0046] like Figure 9 As shown, in some embodiments, the vertical distance between the first base plate 321 and the second base plate 322 is adjustable. For example, the base plate 32 includes a support plate 323, which is disposed at the bottom end of the adhesive container body 31. A magnet 324 is disposed on the support plate 323, which attracts the second base plate 322 to detachably mount the second base plate 322 onto the support plate 323. The first base plate 321 is located between two adjacent second base plates 322. A bolt 325 is disposed on the support plate 323, which abuts against the bottom surface of the first base plate 321. Rotating the bolt 325 can adjust the vertical distance between the first base plate 321 and the second base plate 322. The first base plate 321 is used to contact the heating roller 2. Adjusting the vertical distance between the first base plate 321 and the second base plate 322 can adjust the size of the adhesive flow gap to control the amount of adhesive applied.

[0047] like Figure 10 and Figure 11 As shown, in some embodiments, the edge of the base plate 32 is provided with a plurality of grooves 326 arranged at intervals. When the base plate 32 contacts the heating roller, the grooves 326 and the heating roller 2 form a glue flow gap.

[0048] For example, multiple rectangular teeth are provided on the edge of the base plate 32, and a groove 326 is formed between two adjacent rectangular teeth. The rectangular teeth are used to contact the heating roller 2, and the groove 326 forms a glue flow gap with the heating roller 2. The base plate 32 has a simple structure and is easy to manufacture.

[0049] like Figure 12 and Figure 13 As shown, in some embodiments, a plurality of spring pieces 327 are provided at the end of the base plate 32 near the heating roller 2. For example, an elastic plate is provided on the support plate 323 of the base plate 32, and optionally, the elastic plate is made of spring steel. The end of the elastic plate away from the heating roller 2 is fixed to the support plate 323, and the end of the elastic plate near the heating roller 2 is divided into a plurality of spring pieces 327 arranged in sequence.

[0050] The adhesive container 3 also includes a lifting structure 328, which is mounted on the support plate 323. The lifting structure 328 can lift the spring pieces 327. For example, multiple spring pieces 327 can be lifted at intervals, with the lifted spring pieces 327 contacting the heating roller 2, and the unlifted spring pieces 327 forming adhesive flow gaps with the heating roller 2. Optionally, the lifting structure 328 can be a bolt. Rotating the lifting structure 328 can adjust the force required to lift the corresponding spring pieces 327, thereby adjusting the size of the adhesive flow gaps and thus adjusting the adhesive thickness on the material to be bonded 200.

[0051] In some embodiments, a flexible plate 329 is provided at one end of the spring sheet 327 that contacts the heating roller 2. The flexible plate 329 is used to scrape off the adhesive on the heating roller 2. Optionally, the flexible plate 329 is made of nylon, PTFE, rubber, or polyurethane.

[0052] like Figure 2 As shown, the adhesive container 3 also includes a rotating shaft 33, which is disposed on the outer wall of the adhesive container body 31. The rotating shaft 33 is rotatably connected to the base 1, and the driving component 4 drives the rotating shaft 33 to rotate.

[0053] like Figure 1 As shown, the drive assembly 4 includes a driver 41 and an adapter 42. Optionally, the driver 41 is a cylinder. The driver 41 is rotatably mounted on the base 1, and the output end of the driver 41 is rotatably connected to the adapter 42, which is mounted on the rotating shaft 33. The driver 41 can drive the adapter 42 to rotate, thereby rotating the adhesive container 3 and switching the adhesive container 3 between the first and second working positions.

[0054] like Figure 9 and Figure 13 As shown, the adhesive container 3 also includes a heater 34, which may be a heating wire. The heater 34 is mounted on the adhesive container body 1 via a heat-conducting plate 35. The heater 34 is used to heat the adhesive in the adhesive tank to prevent the adhesive from curing in the adhesive tank.

[0055] like Figure 1 As shown, in some embodiments, the glue-spraying mechanism 100 further includes a first glue-spraying assembly 5, which is disposed on the base 1 and is used to spray glue onto the glue tank and / or the heating roller 2. Optionally, the first glue-spraying assembly 5 is disposed on a conveyor belt, and a conveyor belt driver is disposed on the base 1. The conveyor belt driver is used to drive the conveyor belt to move, and the conveyor belt can drive the first glue-spraying assembly 5 to move its position, so as to adjust the position of the first glue-spraying assembly 5 relative to the glue tank and / or the heating roller 2.

[0056] In some embodiments, the glue rolling mechanism 100 further includes a scraper 6, which is disposed on the base 1 and located at the end of the heating roller 2. The scraper 6 is used to scrape off the glue at the end of the heating roller 2 to prevent the glue on the heating roller 2 from overflowing from the end of the heating roller 2.

[0057] like Figure 14 As shown, an embodiment of this application provides an adhesive application apparatus, which includes a roller adhesive mechanism 100, a support 400, and an application platform 500 as described above.

[0058] Both the glue-rolling mechanism 100 and the coating platform 500 are mounted on the support 100. The glue-rolling mechanism 100 is located above the coating platform 500. A conveyor belt is provided on the coating platform 500 to support and transport the material to be bonded 200. When the material to be bonded 200 passes under the glue-rolling mechanism 100, the glue-rolling mechanism 100 applies glue to the material to be bonded 200, forming spaced glue application areas 210 on the material to be bonded 200.

[0059] like Figure 15 As shown, the adhesive application device also includes a second adhesive spraying assembly 600, which is slidably mounted on the bracket 400. Along the conveying direction of the material to be bonded 200, the second adhesive spraying assembly 600 is located behind the roller adhesive mechanism 100. Optionally, the second adhesive spraying assembly 600 is slidably mounted on the bracket 400 by a cylinder. The sliding direction of the second adhesive spraying assembly 600 is perpendicular to the conveying direction of the material to be bonded 200. The second adhesive spraying assembly 600 is used to spray adhesive onto a preset position on the material to be bonded.

[0060] like Figure 14 and Figure 16As shown, the bracket 400 includes a bracket body 410 and a lifting frame 420. The lifting frame 420 is vertically and flexibly mounted on the bracket body 410, and the glue rolling mechanism 100 and the second glue spraying assembly 600 are both mounted on the lifting frame 420. The up-and-down sliding of the lifting frame 420 drives the glue rolling mechanism 100 and the second glue spraying assembly 600 to rise and fall, so as to accommodate materials 200 of different thicknesses to be glued.

[0061] For example, a vertical guide post 430 is provided on the support body 410, and the lifting frame 420 is slidably mounted on the guide post 430. The base 1 of the glue-rolling mechanism 100 and the second glue-spraying assembly 600 are both mounted on the lifting frame 420. The lifting driver 441 is mounted on the support body 410. The drive end of the lifting driver 441 is connected to a gear 442. The lifting frame 420 is connected to a rack 443, which is adapted to the gear 442. The lifting driver 441 drives the lifting frame 420 to slide up and down through the gear 442 and the rack 443.

[0062] Embodiments of this application also provide an adhesive device, including the adhesive applicator as described above, which applies adhesive to the material to be bonded 200, and the adhesive device bonds multiple layers of the material to be bonded 200 together.

[0063] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the technical solutions and core ideas of this application. Therefore, any changes or modifications made by those skilled in the art based on the ideas of this application, and on the specific implementation methods and application scope of this application, are all within the scope of protection of this application.
