Technical Field
[0001] This utility model relates to the field of paper tube processing technology, and in particular to a device for uniformly applying adhesive for paper tube winding. Background Technology
[0002] A paper tube coating machine is a device used to coat the surface of paper tubes with glue. It is mainly used in the manufacture of paper packaging materials and paper tubes. The coating process can give paper materials waterproof, sealing, and enhanced strength properties. In the early days, during the paper tube winding process, glue was often applied manually or by simple mechanical devices, such as pouring glue into a container and then applying it to the paper with a brush or roller. This method is difficult to ensure the uniformity of glue application, which can lead to quality problems such as glue separation and insufficient strength in the paper tube.
[0003] In the existing technology, the pressure roller presses the paper firmly and fixes it on the conveyor belt. The contact area between the pressure roller and the paper is limited, and there are gaps between the paper and the conveyor belt. The glue may not be evenly applied to the paper surface. In addition, the pressure roller can easily cause the paper to wrinkle during the movement, which affects the glue application.
[0004] The existing patent (publication number: CN221476362U) describes a paper tube gluing machine. It consists of a screw, a pressure roller, and a material roller. Two handwheels rotate the two screws, which move within two screw holes on the top of a fixed frame. The screws cause the retainer to descend, bringing the pressure roller inside the retainer into contact with the paper on the material roller and applying pressure. A motor drives a connecting rod, which in turn rotates the material roller via a fixed rod. The material roller moves the paper and applies glue to its surface. The pressure roller rotates as the paper moves, thus applying pressure to the paper and preventing wrinkles during gluing.
[0005] To address the aforementioned issues, existing patents offer solutions. Existing adhesive application equipment for paper tube winding is not well-suited for paper tubes of different diameters and lengths when applying adhesive to them. This results in situations where, for smaller diameter paper tubes, excessive pressure leads to an overly thick application of adhesive, while for larger diameter paper tubes, insufficient pressure results in an underly thin application of adhesive, or even failure to completely cover the paper tube surface.
[0006] To address this, a device for uniformly applying adhesive during paper tube winding is proposed. Utility Model Content
[0007] The purpose of this invention is to provide a uniform adhesive application device for paper tube winding, which can solve the problem that existing adhesive application devices for paper tube winding are not suitable for paper tubes of different diameters and lengths. This leads to the problem that when applying adhesive to paper tubes with smaller diameters, the pressure is too high, resulting in excessively thick adhesive, while for paper tubes with larger diameters, the pressure is insufficient, resulting in adhesive that is too thin or even fails to completely cover the surface of the paper tube.
[0008] To achieve the above objectives, the present invention provides the following technical solution: a paper tube winding adhesive uniform application device, including a support base, an application component provided on the top of the support base, and a fixing component provided on the left side of the top of the support base;
[0009] The application assembly includes a support frame fixedly connected to the top of a support base. An adjusting hydraulic cylinder is fixedly connected to the top of the support frame.

[0010] Preferably, the fixing component includes a fixing seat slidably connected to the top of the support base, a protective shell fixedly connected to the top of the fixing seat, and a dual-axis hydraulic cylinder fixedly connected inside the protective shell.

[0012] Preferably, the inner side of the support plate is rotatably connected to a slotted plate, and the outer side of the slotted plate is snapped with a fixing member.
[0013] Preferably, an auxiliary frame is fixedly connected to the right side of the top of the support base, an electric telescopic rod is fixedly connected to the top of the auxiliary frame, an auxiliary plate is fixedly connected to the output end of the electric telescopic rod, auxiliary springs are fixedly connected to both sides of the bottom of the auxiliary plate, and a scraper is fixedly connected to the bottom of the auxiliary springs.
[0014] Preferably, a drive motor is fixedly connected to the left side of the support base, a lead screw is fixedly connected to the output end of the drive motor, a connecting block is threaded to the outer side of the lead screw, and the connecting block is fixedly connected to the fixed base.

[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. This application can flexibly adapt to the glue application needs of paper tubes of different diameters through the application component, and also avoids rigid contact between the glue application roller and the paper tube, preventing damage to the surface of the paper tube. At the same time, it ensures that the glue application roller can adhere to the paper tube with appropriate pressure, so that the glue is applied more evenly.
[0019] 2. This application can accommodate paper tubes of various diameters through a fixing component. At the same time, the dual-axis hydraulic cylinder drives the support plates on both sides to move, thereby changing the distance between the two slot plates. This allows for the fixing of paper tubes of different lengths, reducing the trouble of changing equipment or making complicated adjustments due to different paper tube sizes, lowering production costs and improving production efficiency.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please see Figures 1-6 The present invention provides the following technical solution:
[0029] A paper tube winding adhesive uniform application device includes a support base 1, an application component 4 is provided on the top of the support base 1, and a fixing component 5 is provided on the left side of the top of the support base 1.
[0030] The application assembly 4 includes a support frame 401 fixedly connected to the top of the support base 1. An adjusting hydraulic cylinder 402 is fixedly connected to the top of the support frame 401. A top plate 403 is fixedly connected to the output end of the adjusting hydraulic cylinder 402. Limiting rods 404 are fixedly connected to both sides of the top plate 403. Limiting springs 405 are provided on the outer side of the limiting rods 404. A rotary motor 406 is fixedly connected to the rear side of the top plate 403. A glue application roller 407 is fixedly connected to the output end of the rotary motor 406. A glue storage tank 408 is fixedly connected to the right side of the support frame 401. A connecting hose 409 is provided at the bottom of the glue storage tank 408. The connecting hose 409 is connected to the glue application roller 407.
[0031] In this embodiment: by starting the motor body 14 of the glue storage tank 408, the motor body 14 drives the stirring rod 15 to rotate, continuously stirring the glue to ensure uniformity and avoid sedimentation or stratification affecting the coating effect. The adjusting hydraulic cylinder 402 is then activated, its output end pushing the top plate 403 downwards. The limiting rods 404 on both sides of the top plate 403 then move downwards, and the top of the limiting rods 404 presses against the limiting spring 405. The elastic force generated by the limiting spring 405 prevents the glue coating roller 407 from rigidly colliding with the paper tube, thus providing cushioning. In addition to its protective function, the second displacement sensor 13 on the top of the support frame 401 monitors the moving distance of the coating roller 407 in real time and precisely controls the position of the coating roller 407. When the coating roller 407 reaches the appropriate position, the rotary motor 406 and the control pump 16 are started. Then, the rotary motor 406 drives the coating roller 407 to rotate at high speed, and the control pump 16 delivers the glue in the glue storage tank 408 to the inside of the coating roller 407 through the connecting hose 409. Under the rotation of the coating roller 407, the glue is evenly applied to the surface of the paper tube.
[0032] Specifically, such as Figure 3 , Figure 5 As shown, the fixing component 5 includes a fixing seat 501 that is slidably connected to the top of the support seat 1. A protective shell 502 is fixedly connected to the top of the fixing seat 501, and a dual-axis hydraulic cylinder 503 is fixedly connected inside the protective shell 502.
[0033] Specifically, such as Figure 3 , Figure 5 As shown, support plates 504 are fixedly connected to both sides of the dual-axis hydraulic cylinder 503, and a sliding groove 505 is provided on the top of the fixed seat 501. The support plates 504 are slidably connected to the sliding groove 505.
[0034] Specifically, such as Figure 3 , Figure 5 As shown, a slotted plate 506 is rotatably connected to the inner side of the support plate 504, and a fastener 507 is snapped onto the outer side of the slotted plate 506.
[0035] In this embodiment: the card slot 506 is inserted into the inside of the support plate 504, and then the card slot 506 is engaged with the card slot 507 so that the card slot 506 can be fixed to the support plate 504 while rotating flexibly. Then, according to the diameter of the paper tube, a suitable slot is selected in the card slot 506. Then, one end of the paper tube is inserted into one of the card slots 506. Then, the dual-axis hydraulic cylinder 503 is activated. Its output end pushes the two support plates 504 to slide towards each other along the sliding groove 505 on the top of the fixed seat 501. The sliding groove 505 plays a limiting role to ensure that the support plate 504 moves smoothly until the other card slot 506 locks the other end of the paper tube, thereby firmly fixing paper tubes of different lengths and diameters.
[0036] Specifically, such asFigure 4 As shown, an auxiliary frame 2 is fixedly connected to the right side of the top of the support base 1. An electric telescopic rod 3 is fixedly connected to the top of the auxiliary frame 2. An auxiliary plate 6 is fixedly connected to the output end of the electric telescopic rod 3. An auxiliary spring 7 is fixedly connected to both sides of the bottom of the auxiliary plate 6. A scraper plate 8 is fixedly connected to the bottom of the auxiliary spring 7.
[0037] Specifically, such as Figure 5 As shown, a drive motor 9 is fixedly connected to the left side of the support base 1, and a lead screw 10 is fixedly connected to the output end of the drive motor 9. A connecting block 11 is threadedly connected to the outer side of the lead screw 10, and the connecting block 11 is fixedly connected to the fixed base 501.
[0038] In this embodiment: by setting up an auxiliary frame 2, an electric telescopic rod 3, an auxiliary plate 6, an auxiliary spring 7, and a scraper 8, after the paper tube is coated with glue below the support frame 401, the drive motor 9 drives the lead screw 10 to rotate, causing the fixed seat 501 and the paper tube to move to the bottom of the auxiliary frame 2. Then, the electric telescopic rod 3 is activated, extending to push the auxiliary plate 6 and the scraper 8 down. The auxiliary spring 7 adaptively adjusts the position of the scraper 8 according to the surface condition of the paper tube. The scraper 8 contacts the surface of the paper tube and moves to scrape off excess glue, so as to avoid glue accumulation affecting the winding quality of the paper tube. At the same time, the auxiliary spring 7 can adapt to the surface differences of different paper tubes, ensuring a stable scraping effect. By setting up a drive motor 9, a lead screw 10, and a connecting block 11, starting the drive motor 9 causes the lead screw 10 to rotate. The rotation of the lead screw 10 then moves the connecting block 11 on the lead screw 10. The connecting block 11 then moves the fixed seat 501, transporting the paper tube to the area below the coating component 4 for glue application. After the glue application is completed, starting the drive motor 9 again causes the fixed seat 501 to move the paper tube to the area below the auxiliary frame 2 for subsequent processing. This system enables automatic and precise movement of the paper tube between different process positions, ensuring that the paper tube accurately reaches the glue application and scraping positions, improving the automation level of the equipment, reducing the intensity of manual operation, and increasing production efficiency.
[0039] Specifically, such as Figure 4 , Figure 6 As shown, the top of the auxiliary frame 2 is provided with a first displacement sensor 12, and the top of the support frame 401 is provided with a second displacement sensor 13.
[0040] Specifically, such as Figure 6 As shown, a motor body 14 is fixedly connected to the top of the glue storage tank 408, a stirring rod 15 is fixedly connected to the output end of the motor body 14, a control pump 16 is connected to the bottom of the glue storage tank 408, and a connecting hose 409 is connected to the output end of the control pump 16.
[0041] In this embodiment: by setting a first displacement sensor 12 and a second displacement sensor 13, the first displacement sensor 12 ensures that the paper tube moves accurately to the designated position in the horizontal direction, improving the position control accuracy. At the same time, the second displacement sensor 13 ensures that the glue coating roller 407 contacts the paper tube stably and accurately in the vertical direction, ensuring uniform glue application, improving the stability of equipment operation and product quality. By setting a motor body 14, a stirring rod 15, and a control pump 16, before glue application, the motor body 14 is started, and then the motor body 14 drives the stirring rod 15 to stir the glue in the glue storage tank 408. During glue application, the control pump 16 is started, and then the control pump 16 delivers the glue from the glue storage tank 408 to the glue coating roller 407 through the connecting hose 409. The stirring rod 15 stirs the glue, which can prevent glue sedimentation and stratification, ensuring the stability of glue performance and uniform composition, resulting in better glue application. The control pump 16 precisely controls the glue delivery amount, avoiding glue waste, ensuring a stable glue supply, and meeting different production needs.
[0042] Working principle: During the process of evenly applying adhesive for paper tube winding, firstly, insert the slot plate 506 into the inside of the support plate 504, and then use the fixing piece 507 to engage with the slot plate 506. This allows the slot plate 506 to rotate freely while still being fixed to the support plate 504. Next, select a suitable slot in the slot plate 506 according to the diameter of the paper tube. Then, insert one end of the paper tube into one of the slot plates 506. Subsequently, start the dual-axis hydraulic cylinder 503. Its output end pushes the two support plates 504 to slide towards each other along the sliding groove 505 on the top of the fixed base 501. The sliding groove 505 acts as a limit, ensuring that the support plate 504 moves smoothly until the other slot plate 506 engages. Hold the other end of the paper tube to securely fix paper tubes of different lengths and diameters. After fixing the paper tubes, start the drive motor 9 on the left side of the support base 1. The motor output then drives the lead screw 10 to rotate. The lead screw 10 then drives the connecting block 11, which is threaded to it. The connecting block 11 then moves the fixed base 501 and the paper tubes on it. When the paper tubes move to the bottom of the support frame 401, the drive motor 9 stops working. Then, add glue to the glue storage tank 408 and start the motor body 14 of the glue storage tank 408. The motor body 14 then drives the stirring rod 15 to rotate, continuously stirring the glue to ensure that the glue is uniform and to avoid sedimentation or layering that would affect the application effect. Start the adjusting hydraulic cylinder 402. Its output end pushes the top plate 403 down, and then the limiting rods 404 on both sides of the top plate 403 move downward accordingly. Then, the top of the limiting rod 404 squeezes the limiting spring 405. The elastic force generated by the limiting spring 405 prevents the glue coating roller 407 from rigidly colliding with the paper tube, thus playing a buffering and protective role. At the same time, the second displacement sensor 13 on the top of the support frame 401 monitors the moving distance of the glue coating roller 407 in real time and precisely controls the position of the glue coating roller 407. When the glue coating roller 407 reaches the appropriate position, the rotary motor 406 and the control pump 16 are started. Then, the rotary motor 406 drives the glue coating roller 407 to rotate at high speed, and the control pump 16 pumps the glue in the glue storage tank 408 through the connecting soft The tube 409 is fed into the glue-coating roller 407. Under the rotation of the glue-coating roller 407, the glue is evenly applied to the surface of the paper tube. After the paper tube is glued, the drive motor 9 is started again. Through the cooperation of the lead screw 10 and the connecting block 11, the fixed seat 501 and the paper tube are moved to the bottom of the auxiliary frame 2. At this time, the electric telescopic rod 3 at the top of the auxiliary frame 2 is started. Then the electric telescopic rod 3 pushes the auxiliary plate 6 and the scraper 8 downward. The auxiliary springs 7 on both sides of the bottom of the auxiliary plate 6 enable the scraper 8 to adapt to the unevenness of the paper tube surface. During the movement, the scraper 8 scrapes off the excess glue on the surface of the paper tube, ensuring that the glue is evenly applied to the surface of the paper tube and there is no excess glue residue, thus improving the winding quality of the paper tube.
[0043] 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, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
