Description

Technical Field

[0001] This utility model relates to the field of paperboard processing technology, and in particular to a gluing mechanism for a paperboard production line. Background Technology

[0002] As a material widely used in the packaging industry, one of the key steps in the production process of cardboard is gluing. The gluing mechanism can precisely control the amount and uniformity of glue application to ensure a strong bond between the corrugated base paper and the face paper.

[0003] During processing, the existing gluing mechanism may cause glue to overflow from both sides of the cardboard. If the edges and corners of the cardboard are not treated, the dripping glue will spill everywhere, which will not only pollute the production environment but also damage the surface of the cardboard. Therefore, it is necessary to provide a gluing mechanism for the cardboard production line to promptly remove the glue overflow from both sides of the cardboard and prevent glue from dripping everywhere and affecting the cleanliness of the cardboard surface. Utility Model Content

[0004] The purpose of this utility model is to provide a gluing mechanism for a cardboard production line, so as to solve the problem mentioned in the background art that when the existing gluing mechanism is processed, glue will overflow on both sides of the cardboard. If the corners of the cardboard are not treated, the dripping glue will be scattered in various places, which will not only pollute the production environment, but also damage the surface of the cardboard.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a gluing mechanism for a cardboard production line, comprising:

[0007] The gluing assembly includes a glue applicator body, a glue roller, a glue storage tank, a plunger pump, and a delivery pipe. The glue roller is located on top of the glue applicator body, the glue storage tank is located on one side of the glue applicator body, the plunger pump is located on top of the glue storage tank, and the delivery pipe is fixed between the plunger pump output pipe and the glue roller.

[0008] The glue-scraping assembly is located at one end of the glue-applying assembly. The glue-scraping assembly includes a fixed frame, a movable frame, a scraper, a support frame, and a collection frame. The fixed frames are fixed on both sides of the outer surface of the glue applicator body. There are two sets of fixed frames. The movable frame is slidably connected to the inside of any set of fixed frames. The scraper is fixed to the outer surface of the top of the movable frame. The support frame is fixed to the outer surface of the bottom of the movable frame. The collection frame is sleeved inside the support frame.

[0009] Furthermore, a fixing plate is fixed to the lower surface of the collection frame, and a guide plate is fixed to the outer surface of the collection frame.

[0010] Furthermore, a rotating column is rotatably connected inside the fixed plate, the top of the rotating column is located inside the guide plate, and a threaded column is threadedly connected inside the rotating column and the guide plate, with a guide block fixed on the outer surface of the threaded column.

[0011] Furthermore, it also includes a limiting component, which includes a guide post, a limiting hole, a support frame, and a fixing tube; the guide post is fixed to the outer surface of the movable frame and is connected through the interior of the fixed frame; the limiting hole is opened inside the guide post and is equidistantly distributed; the support frame is fixed to the outer surface of the fixed frame; and the fixing tube is fixed to the outer surface of the support frame.

[0012] Furthermore, a spring is fixed to the outer surface of the support frame, the spring is located inside the fixed tube, and a connecting block is fixed to the outer surface of the spring.

[0013] Furthermore, a limiting post and a guide rod are respectively fixed to the outer surfaces of both ends of the connecting block. The limiting post is connected through the interior of the guide post, and the guide rod is connected through the interior of the support frame.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through its designed scraper and gluing components, allows for the timely application of glue to the surface of cardboard. First, the movable frame is moved to the desired position within the fixed frame. The cardboard is placed on the main body of the gluing machine, and the gluing component is switched on, causing the cardboard to move to the bottom of the glue roller. As the glue roller rotates, this process not only completes the gluing of the cardboard but also removes it from the main body of the gluing machine. During this process, the sides of the cardboard rub against the scraper, scraping excess glue onto the sides of the cardboard into the collection frame. When it is necessary to clean the glue inside the collection frame, a rotational force is applied to the guide block, causing the threaded column to disengage from the guide plate. A rotational force is then applied to the rotating column, causing it to disengage from the guide plate. Finally, a pulling force is applied to the guide plate, pulling the collection frame out of the support frame. This solution effectively removes excess glue from the sides of the cardboard, preventing glue from dripping everywhere and affecting the cleanliness of the cardboard surface.

[0016] II. Based on the first beneficial effect, when the movable frame needs to be fixed in the required position with the help of the limiting components, first apply a pulling force to the guide rod. The connecting block drives the limiting post to disengage from the inside of the guide post. Then apply a pulling force to the guide post. After the guide post moves the movable frame to the required position, release the force applied to the guide rod. Under the action of the spring force, the connecting block drives the limiting post to move into the corresponding limiting hole. This solution allows the spacing between the scrapers to be adjusted according to the actual width of the cardboard. Attached Figure Description

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figures 1-4 As shown, this embodiment is a gluing mechanism for a paperboard production line, comprising:

[0030] The gluing assembly 1 includes a glue applicator body 11, a glue roller 12, a glue storage tank 13, a plunger pump 14, and a delivery pipe 15. The glue roller 12 is located on the top of the glue applicator body 11, the glue storage tank 13 is located on one side of the glue applicator body 11, the plunger pump 14 is located on the top of the glue storage tank 13, and the delivery pipe 15 is fixed between the output pipe of the plunger pump 14 and the glue roller 12.

[0031] The glue applicator body 11 serves as the basic frame of the entire glue application assembly 1, supporting and fixing other components to achieve the glue application operation. The glue storage tank 13 is used to store glue, and the plunger pump 14 is used to transport the glue inside the glue storage tank 13 to the glue roller 12 through the conveying pipe 15. The glue roller 12 has multiple permeation holes on its surface, which are connected to the glue conveying pipe 15. The glue roller 12 utilizes capillary action to draw the glue into its interior and permeate its surface, driving the glue roller 12 to rotate. During the rotation, the glue forms a uniform glue film on the surface of the glue roller 12. When the glue roller 12 rotates, the glue on its surface is carried to the position that contacts the cardboard, completing the glue application operation.

[0032] The glue-scraping assembly is located at one end of the glue-applying assembly. The glue-scraping assembly includes a fixed frame 21, a movable frame 22, a scraper 23, a support frame 24, and a collection frame 25. The fixed frame 21 is fixed on both sides of the outer surface of the glue applicator body 11. There are two sets of fixed frames 21. The movable frame 22 is slidably connected to the inside of any set of fixed frames 21. The scraper 23 is fixed to the outer surface of the top of the movable frame 22. The support frame 24 is fixed to the outer surface of the bottom of the movable frame 22. The collection frame 25 is sleeved inside the support frame 24.

[0033] The fixed frame 21 provides a sliding track for the movable frame 22. By adjusting the position of the movable frame 22, the relative position between the scraper 23 and the cardboard can be changed. The scraper 23 contacts the surface of the cardboard, thereby scraping off excess glue from the surface of the cardboard. The support frame 24 is used to place the collection frame 25, which is used to collect the glue scraped off by the scraper 23.

[0034] A fixing plate 27 is fixed to the lower surface of the collection frame 25, and a guide plate 26 is fixed to the outer surface of the collection frame 25.

[0035] The fixing plate 27 is used to support and install the rotating column 28, while the guide plate 26 facilitates the application of pulling force to the collection frame 25.

[0036] The fixed plate 27 is rotatably connected to a rotating column 28. The top of the rotating column 28 is located inside the guide plate 26. The rotating column 28 and the guide plate 26 are threadedly connected to a threaded column 29. A guide block 291 is fixed on the outer surface of the threaded column 29.

[0037] The rotating column 28 is inserted into the inside of the guide plate 26, and the threaded column 29 is rotated into the inside of the guide plate 26, which can restrict the collection frame 25 inside the support frame 24. The guide block 291 facilitates the application of rotational force to the threaded column 29.

[0038] Working principle: When it is necessary to apply glue to the surface of the cardboard, first move the movable frame 22 to the desired position inside the fixed frame 21, place the cardboard on the glue applicator body 11, turn on the switch of the glue applicator 1, so that the cardboard moves to the bottom of the glue roller 12. Since the glue roller 12 is in a rotating state, it not only completes the glue application to the cardboard, but also drives the cardboard to detach from the glue applicator body 11. During this process, the two sides of the cardboard rub against the scraper 23, thereby scraping the excess glue on both sides of the cardboard into the inside of the collection frame 25. When it is necessary to clean the glue inside the collection frame 25, apply a rotational force to the guide block 291, so that the threaded column 29 disengages from the inside of the guide plate 26. Apply a rotational force to the rotating column 28, so that the rotating column 28 disengages from the inside of the guide plate 26. Apply a pulling force to the guide plate 26 to pull the collection frame 25 out of the support frame 24.

[0039] This step involves promptly removing excess glue from both sides of the cardboard to prevent it from dripping everywhere and affecting the cleanliness of the cardboard surface.

[0040] Please see Figures 1-3 As shown, this embodiment, based on the above embodiment, further includes a limiting component. The limiting component includes a guide post 31, a limiting hole 32, a support frame 33, and a fixing tube 34. The guide post 31 is fixed to the outer surface of the movable frame 22 and is connected through the interior of the fixed frame 21. The limiting hole 32 is opened inside the guide post 31 and is equidistantly distributed. The support frame 33 is fixed to the outer surface of the fixed frame 21, and the fixing tube 34 is fixed to the outer surface of the support frame 33.

[0041] The guide post 31 facilitates the movement of the movable frame 22 to the desired position. The limiting hole 32 is used to cooperate with the limiting post 37 to restrict the movable frame 22 to the desired position. The support frame 33 is used to install the fixing tube 34 and the spring 35. The fixing tube 34 plays the role of protecting and positioning the spring 35.

[0042] A spring 35 is fixed to the outer surface of the support frame 33. The spring 35 is located inside the fixing tube 34. A connecting block 36 is fixed to the outer surface of the spring 35.

[0043] Spring 35 generates elastic force. When the external force is removed, the elastic force of spring 35 can restore the connecting block 36 to its original position. The connecting block 36 is used to support and install the limiting post 37 and the guide rod 38.

[0044] Limiting posts 37 and guide rods 38 are respectively fixed to the outer surfaces of both ends of the connecting block 36. The limiting posts 37 are connected through the interior of the guide posts 31, and the guide rods 38 are connected through the interior of the support frame 33.

[0045] The limiting post 37 is used to limit the position of the guide post 31, while the guide rod 38 facilitates changing the position of the connecting block 36.

[0046] Working principle: When it is necessary to fix the movable frame 22 in the required position, first apply a pulling force to the guide rod 38. The connecting block 36 drives the limiting post 37 to disengage from the inside of the guide post 31. Apply a pulling force to the guide post 31. After the guide post 31 moves the movable frame 22 to the required position, release the force applied to the guide rod 38. Under the elastic force of the spring 35, the connecting block 36 drives the limiting post 37 to move into the corresponding limiting hole 32.

[0047] This step allows you to adjust the spacing between the scrapers 23 according to the actual width of the cardboard.
