Description

Technical Field

[0001] This utility model relates to the field of composite coating machine technology, specifically to a corrugated cardboard double-wall composite coating machine that can precisely control the amount of adhesive applied. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper. It has high mechanical strength and can withstand collisions and drops during handling. Currently, the bonding between the cardboard layers of corrugated cardboard requires gluing treatment on their surfaces during production.

[0003] A search revealed an existing patent (publication number: CN 217512203 U) disclosing a double-walled composite coating machine for a corrugated cardboard production line. The machine includes a coating frame, a lifting hollow material platform, and an upper hollow plate. It also includes a hydraulic push rod and an industrial vacuum cleaner. A first and second coating roller are rotatably mounted on one side of the top of the coating frame via bearings. A glue discharge pipe is bolted to the top of the coating frame. The lifting hollow material platform is located at the bottom of the coating frame, with sliders at its corners. The upper hollow plate is bolted to the top of the coating frame. This double-walled composite coating machine for the entire corrugated cardboard production line is flexible and convenient to use, suitable for coating corrugated cardboard of various thicknesses. It also allows for pre-cleaning of the corrugated cardboard to be coated, improving the contact between the adhesive and the cardboard and resulting in better bonding between the corrugated sheets. It is highly practical.

[0004] However, in the above solution, the coating machine cannot adjust the amount of glue applied when applying glue to the cardboard. If too much glue is dispensed, it will lead to glue waste, while if too little glue is dispensed, it will not be able to coat the surface of the cardboard well.

[0005] In view of this, this utility model proposes a corrugated cardboard double-wall composite coating machine that can precisely control the amount of adhesive applied. Utility Model Content

[0006] This invention proposes a double-wall corrugated cardboard coating machine that can precisely control the amount of glue applied, solving the problem that related technologies cannot adjust the amount of glue applied. When the amount of glue applied is too much, it will lead to glue waste, while when the amount of glue applied is too little, it will not be able to coat the surface of the cardboard well.

[0007] The technical solution of this utility model is as follows: A corrugated cardboard double-wall composite coating machine that can precisely control the amount of adhesive applied includes a base, a side plate is fixedly connected to the top of the base, and an adjustment mechanism is provided on the side of the side plate. The adjustment mechanism includes a connecting component and an adjustment component.

[0008] Preferably, the connecting assembly includes a motor, a first gear, a second gear, a connecting tube, a first dispensing tube, a second dispensing tube, and an outlet.

[0009] Preferably, the motor is fixedly connected to the surface of the side plate, the output end of the motor is fixedly connected to a first gear, the bottom of the first gear is meshed with a second gear, a connecting tube is fixedly connected to one side of both the first gear and the second gear, a first glue outlet tube is fixedly connected to the tail of both sets of connecting tubes, a second glue outlet tube is attached to the surface of both sets of first glue outlet tubes, and an outlet is provided on the surface of both sets of first glue outlet tubes and second glue outlet tubes.

[0010] Preferably, the connecting tube and the first dispensing tube are interconnected, and there is no gap between the first dispensing tube and the second dispensing tube.

[0011] Preferably, the adjustment assembly includes a connecting groove, an insert rod, a handle, and a nut.

[0012] Preferably, the connecting groove is disposed on the side of the two sets of first dispensing tubes, and an insert rod is embedded and slidably connected inside the two sets of connecting grooves. The tail of the two sets of insert rods is fixedly connected to a handle that is fixedly connected to the first dispensing tube, and a nut is threadedly connected to the surface of the two sets of insert rods.

[0013] Preferably, both sets of connecting tubes have grooves on their surfaces, both sets of grooves have connecting holes inside, both sets of grooves have hollow rings that fit tightly against the connecting holes inside, both sets of hollow rings have recesses inside, both sets of hollow rings have glue guide tubes fixedly connected to their sides, both sets of side plates have two sets of scrapers fixedly connected to their inner walls, both sets of scrapers have a collecting plate that slides below the side plates, both sets of collecting plates have a threaded rod that is threadedly connected to the side plates below the collecting plates, and both sets of threaded rods have a stop block that slides rotatably connected to the side plates at their top.

[0014] Preferably, the stop block and the collecting plate are in a tightly fitted state, the collecting plate is fixed by the stop block, the stop block and the collecting plate are in a tightly fitted state, the collecting plate is fixed by the stop block, and the hollow ring is provided with circular retaining rings on both sides, the retaining rings on the side of the hollow ring are embedded into the embedding grooves provided inside the retaining grooves and are tightly fitted therewith.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] In this invention, by setting an outlet, when it is necessary to adjust the amount of glue dispensed, the nut can be loosened and the handle can be rotated. When the handle is rotated, the embedded rod will slide along the inside of the connecting groove and the first glue dispensing tube will rotate inside the second glue dispensing tube. When the first glue dispensing tube rotates, the outlet on its surface will gradually move away from the outlet on the second glue dispensing tube. This achieves the purpose of maximizing the glue dispensing amount when the two sets of outlets coincide and gradually reducing the dispensing amount when the two sets of outlets move away from each other.

[0017] 2. In this utility model, a scraper is provided to remove excess glue from the surface of the cardboard after gluing. The scraped glue will flow into the interior of the collecting plate. When the collecting plate needs to be removed, the threaded rod can be rotated to make the stop block descend and no longer stick to the collecting plate. At this time, the collecting plate can slide to the side to achieve the purpose of disassembling the collecting plate, which is convenient for the glue inside the collecting plate to be processed or reused.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example 1

[0026] A preferred embodiment of the corrugated cardboard double-wall composite coating machine that can precisely control the amount of adhesive applied, provided by this utility model, is as follows: Figures 1 to 5 As shown: A corrugated cardboard double-wall composite coating machine that can precisely control the amount of adhesive applied includes a base 1, a side plate 2 fixedly connected to the top of the base 1, and an adjustment mechanism 3 provided on the side of the side plate 2. The adjustment mechanism 3 includes a connecting component 31 and an adjustment component 32.

[0027] In this embodiment, the connecting component 31 includes a motor 311, a first gear 312, a second gear 313, a connecting tube 314, a first dispensing tube 315, a second dispensing tube 316, and an outlet 317. By setting the connecting component 31, it is convenient to control the rotation of the first dispensing tube 315 and the second dispensing tube 316.

[0028] In this embodiment, the motor 311 is fixedly connected to the surface of the side plate 2. The output end of the motor 311 is fixedly connected to the first gear 312. The bottom of the first gear 312 meshes with the second gear 313. A connecting tube 314 is fixedly connected to one side of both the first gear 312 and the second gear 313. A first dispensing tube 315 is fixedly connected to the tail of both sets of connecting tubes 314. A second dispensing tube 316 is attached to the surface of both sets of first dispensing tubes 315. An outlet 317 is provided on the surface of both sets of first dispensing tubes 315 and second dispensing tubes 316.

[0029] In this embodiment, the connecting tube 314 and the first dispensing tube 315 are designed to be interconnected. There is no gap between the first dispensing tube 315 and the second dispensing tube 316. The first dispensing tube 315 and the second dispensing tube 316 are tightly fitted together, which can effectively prevent glue from flowing out from the gap between them.

[0030] In this embodiment, the adjustment component 32 includes a connecting groove 321, an embedded rod 322, a handle 323, and a nut 324. By setting the adjustment component 32, the amount of glue dispensed can be adjusted.

[0031] In this embodiment, the connecting groove 321 is provided on the side of the two sets of first dispensing tubes 315. The two sets of connecting grooves 321 are each embedded with a sliding connecting rod 322. The tail of the two sets of connecting rods 322 is fixedly connected with a handle 323 that is fixedly connected to the first dispensing tube 315. The surface of the two sets of connecting rods 322 is threaded with a nut 324. Example 2

[0032] Based on Example 1, a preferred embodiment of the corrugated cardboard double-wall composite coating machine with precise control over adhesive application amount provided by this utility model is as follows: Figures 1 to 5 As shown: Both sets of connecting tubes 314 have slots 5 on their surfaces, both sets of slots 5 have connecting holes 4 inside, both sets of slots 5 have hollow rings 6 that fit tightly with the connecting holes 4 inside, both sets of hollow rings 6 have recessed holes 7 inside, both sets of hollow rings 6 have glue guide tubes 8 fixedly connected to their sides, both sets of scrapers 9 are fixedly connected to the inner side wall of the side plate 2, both sets of scrapers 9 are provided below the side plate 2 with a collection plate 10 that is slidably connected to the side plate 2, both sets of collection plates 10 are provided below the collection plate 10 with a threaded rod 11 that is threadedly connected to the side plate 2, and both sets of threaded rod 11 are rotatably connected to a stop block 12 that is slidably connected to the side plate 2.

[0033] In this embodiment, the stop block 12 and the collecting plate 10 are in a tight fit. The collecting plate 10 is fixed by the stop block 12. Circular retaining rings are provided on both sides of the hollow ring 6. The retaining rings on the side of the hollow ring 6 are embedded in the embedded groove provided inside the retaining groove 5 and are in tight fit with it. When it is necessary to remove the collecting plate 10, the threaded rod 11 can be rotated to make it drive the stop block 12 down and no longer fit with the collecting plate 10. At this time, the collecting plate 10 can slide to the side to achieve the purpose of removing the collecting plate 10, which is convenient for the glue inside the collecting plate 10 to be treated or reused.

[0034] The working principle and usage process of this utility model are as follows: First, when applying glue to corrugated cardboard, the glue can be introduced into the connecting tube 314 through the glue guide tube 8, and then into the first glue outlet tube 315 through the connecting tube 314 to prepare for glue application. Then, the motor 311 is turned on to control the first gear 312 to rotate clockwise, and the second gear 313, which meshes with the first gear 312, will rotate counterclockwise. When the first gear 312 and the second gear 313 rotate relative to each other, the first glue outlet tube 315 and the second glue outlet tube 316, which are fixedly connected to them, will also move accordingly. When the 16 rotates, the glue inside the first glue tube 315 will flow out from the inside of the outlet 317, and the flowing glue will flow out from the outlet 317 on the second glue tube 316. This is to apply glue to the corrugated cardboard passing through the gap between the two sets of second glue tubes 316. Because the hollow ring 6 and the slot 5 are in a mutually engaged state, when the glue guide tube 8 introduces the glue into the hollow ring 6, the glue will flow out through the concave hole 7 and enter the interior of the connecting tube 314 through the connecting hole 4, thereby realizing the transfer of glue. When the motor 311 drives the connecting tube 314 to rotate, it will not drive the hollow ring 6 engaged with the slot 5 to rotate, so the glue guide tube 8 will not be entangled.

[0035] When it is necessary to adjust the amount of glue dispensed, the nut 324 can be loosened, and then the handle 323 can be rotated. When the handle 323 is rotated, the embedded rod 322 will slide along the inside of the connecting groove 321, and the first glue dispensing tube 315 will rotate inside the second glue dispensing tube 316. When the first glue dispensing tube 315 rotates, the outlet 317 on its surface will gradually move away from the outlet 317 on the second glue dispensing tube 316. This achieves the purpose of maximizing the glue dispensing amount when the two sets of outlets 317 are in the same position, and gradually reducing the glue dispensing amount when the two sets of outlets 317 move away from each other.

[0036] By setting up the scraper 9, the scraper 9 can scrape off the excess glue on the surface of the cardboard after gluing, and the scraped glue will flow into the interior of the collecting plate 10. When it is necessary to remove the collecting plate 10, the threaded rod 11 can be rotated to make it drive the stop 12 down and no longer stick to the collecting plate 10. At this time, the collecting plate 10 can slide to the side to achieve the purpose of removing the collecting plate 10, which makes it convenient to process or reuse the glue inside the collecting plate 10.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
