Description

Technical Field

[0001] This invention relates to the field of paper tube production technology, and more specifically to a rolling and forming device for multi-layer composite high-strength paper tubes. Background Technology

[0002] Paper tubes are tubular products made from paper. They have advantages such as low cost, recyclability, and good processing performance, and are widely used in roll products in industries such as textiles, packaging, papermaking, fireworks, and food. Examples include fabric cores, paper cores, plastic film cores, cling film cores, and toilet paper cores. They are indispensable components in daily life and industrial production. With the increasing demands for load-bearing capacity and durability from various industries, multi-layer composite high-strength paper tubes are gradually becoming the market mainstream.

[0003] The paper tube rolling process is mainly divided into two types: flat winding and spiral winding. In the paper tube production process, glue application is one of the key steps that determines the quality of the paper tube. The uniformity, width, and thickness of the glue coating directly affect the bonding strength between multiple layers of paper, and thus determine the overall structural stability and service life of the paper tube.

[0004] Excess glue at both ends of the glue rollers in existing glue coating devices cannot be effectively removed, causing glue to be applied to areas outside the paper. This not only wastes glue but also easily contaminates the equipment and other components. Furthermore, the existing glue coating thickness is difficult to adapt quickly due to differences in paper thickness.

[0005] During long-term use, paper scraps and cured adhesive easily adhere to the surface of the coating roller. If not cleaned in time, it will seriously affect the uniformity of subsequent coating. Although the existing technology is equipped with a scraping mechanism, the scraped waste often falls directly into the glue tank or inside the equipment, causing secondary pollution. The coating area is easily contaminated by external dust and paper scraps. Impurities falling into the adhesive will affect the quality of the adhesive and thus reduce the bonding strength of the paper tube.

[0006] Therefore, it is necessary to invent a rolling and forming device for multi-layer composite high-strength paper tubes to solve the above problems. Summary of the Invention

[0007] The purpose of this invention is to provide a rolling and forming device for multi-layer composite high-strength paper tubes. It achieves automatic glue replenishment through the air pressure difference between the storage tank and the glue coating chamber, maintaining a constant liquid level and ensuring stable glue application on the coating roller. The device uses an electric push rod to drive a concentrating component and a thinning component to precisely adjust the glue coating width and thickness, adapting to different paper sizes. A scraping component promptly cleans and collects residues from the roller surface, preventing secondary contamination. A fan creates a room-temperature air curtain, which, combined with an inclined cover plate, prevents dust accumulation without accelerating glue curing. This invention solves the problems in the prior art.

[0013] As a preferred embodiment of the present invention, fans are installed on both sides of the inside of the glue coating cavity, and the air outlet of the fans is arranged facing the gap between the pressing roller and the glue coating cavity, so as to form an air curtain on the side of the pressing roller.

[0014] In a preferred embodiment of the present invention, the paint roller is rotatably connected inside the glue-applying cavity, a fixing block is fixedly connected to the bottom of the glue-applying cavity, a paint brush is fixedly connected to the top of the fixing block, the paint brush is in contact with the paint roller, and the height of the glue inlet channel is greater than the top of the paint brush.

[0015] In a preferred embodiment of the present invention, the focusing component includes two symmetrical spiral scraper rods. A scraper blade that conforms to the coating roller is provided on the inner side of each spiral scraper rod. An active block is fixedly connected to the top of each spiral scraper rod. Electric push rods are installed on both sides of the lifting frame. A push rod is fixedly connected to the output end of each electric push rod, and the push rod is fixedly connected to the active block. A driven block is fixedly connected to the bottom of each spiral scraper rod, and a limiting rod that is fixedly connected to the lifting frame is slidably connected inside the driven block.

[0016] In a preferred embodiment of the present invention, the thinning assembly includes a C-shaped frame, which is fixedly connected to the inner side of the lifting frame. An electric push rod three is fixedly installed on the outer side of the C-shaped frame, and a push plate is fixedly connected to the output end of the electric push rod three. A limiting groove is formed on the inner side of the C-shaped frame. Limiting blocks that are slidably connected to the limiting groove are fixedly connected to both sides of the push plate. A pusher blade that cooperates with the coating roller is fixedly connected to the bottom of the push plate.

[0017] In a preferred embodiment of the present invention, the scraping assembly includes a first scraping blade and a second scraping blade. A first guide plate is fixedly connected to the outer side of the first scraping blade, and a second guide plate is fixedly connected to the outer side of the second scraping blade. A material separating blade is provided at the connection of the first scraping blade. A discharge conduit is integrally fixedly connected to the outer side of the second scraping blade and the second guide plate. A discharge groove is provided on the side wall of the lifting frame.

[0018] Compared with the prior art, the technical effects and advantages provided by the present invention in the above technical solution are as follows: By installing an automatic liquid level balancing mechanism in the coating chamber, the pressure difference between the storage tank and the coating chamber is utilized to automatically maintain a constant liquid level, ensuring that the coating roller is always immersed in the liquid, thus achieving long-term stability of the coating amount. Simultaneously, a concentrating component and a thinning component are sequentially installed on the paper feed side of the coating roller. The concentrating component adjusts the blade position according to the paper width to remove excess liquid from both ends of the coating roller, ensuring precise matching of the coating width to the paper. The thinning component adjusts the gap between the pusher blade and the coating roller as needed to precisely control the coating thickness. After coating, the thinning component promptly removes residual paper scraps and excess liquid from the coating roller surface, preventing impurities from contaminating the liquid and affecting subsequent coating quality. The coordinated action of these multi-level control mechanisms achieves precise control of coating width, thickness, and cleanliness, resulting in uniform coating, reliable adhesion, and strong bonding between multiple layers of paper, effectively improving the interlayer bonding strength and overall structural stability of the paper tube. A scraping component is installed on the paper-out side of the coating roller assembly. After the coating roller completes the coating, the first scraper and the second scraper thoroughly scrape off the paper scraps and excess glue residue on the roller surface. The scraped waste is blocked by the second guide plate and falls into the discharge pipe, and finally into the waste tank for centralized collection. This effectively prevents impurities from re-entering the coating chamber and contaminating the glue, and also avoids the glue from adhering to the coating roller surface after drying and affecting the subsequent coating effect. At the same time, the inclined cover plate can prevent paper scraps from falling into the coating chamber from above, further ensuring the cleanliness of the coating environment. By installing fans on both sides of the glue coating chamber, a weak air curtain can be formed on the side of the glue coating chamber, which effectively blocks external dust, paper scraps and other impurities from entering the glue coating area, ensuring the cleanliness of the glue coating environment. At the same time, the air curtain is a normal temperature airflow, which is used for physical isolation and dust prevention. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] This invention provides, for example Figure 1-12 The apparatus shown is a winding and forming device for multi-layer composite high-strength paper tubes, comprising: The winding power assembly 001 includes a processing platform 101, a baffle 102 fixedly connected to the top of the processing platform 101, a winding rod 103 fixedly connected to the inner side of the baffle 102, and a drive assembly installed on the top of the processing platform 101. Multiple sets of feeding assemblies 002 are installed on the side of the winding power assembly 001 to feed the paper to the outside of the winding rod 103. Multiple sets of glue application brackets 003 are respectively arranged below the feeding assembly 002. Each glue application bracket 003 includes a fixed frame 301, and a lifting frame 303 is slidably connected inside the fixed frame 301. The lifting frame 303 includes a glue application chamber 304 and a material storage tank 308. The coating roller assembly 004 is installed inside the coating chamber 304 and is used to coat paper with glue, including a coating roller 401; The focusing component 005 and the thinning component 006 are installed on the outside of the glue coating roller assembly 004, on the side close to the paper input direction. The scraping component 007 is installed on the outside of the glue coating roller assembly 004, on the side near the paper output direction.

[0024] In use, the user can feed multiple sheets of paper through the feeding assembly 002. Before entering the winding power assembly 001, the paper is coated with glue through the glue-coating bracket 003. After feeding, the paper is wound into the outer side of the winding rod 103. The drive assembly drives the multiple sheets of paper to be wound up. For the innermost sheet of paper, a lubricating coating is provided inside the glue-coating bracket 003. For other sheets of paper, an adhesive that increases viscosity is provided inside the glue-coating bracket 003, thereby improving the stability of the paper tube.

[0025] The drive assembly includes a drive roller 104 and a driven roller 105, which are rotatably connected to the top of the processing platform 101 on both sides of the winding rod 103. The drive roller 104 is driven by a motor, and a transmission belt 106 connects the drive roller 104 and the driven roller 105. The feeding assembly 002 also includes a support frame 201, with a feed roll 202 rotatably connected to the front end of the support frame 201 and a pressing roller 204 rotatably connected to the rear end. Multiple guide rollers 203 are arranged between the feed roll 202 and the pressing roller 204. The paper is unwound from the feed roll 202, wound around the guide rollers 203 and the pressing roller 204, and then extended to the outside of the winding rod 103 for winding.

[0026] After the paper is drawn out from the unwind roll 202, it passes through the roller 203 and enters the glue-coating bracket 003. Glue is applied to one side of the paper. Subsequently, the paper is guided at an inclined angle to the surface of the winding rod 103. The winding rod 103 is fixed and has a drive device on its periphery. The drive belt 106 is spirally wrapped around the outside of the mandrel. The drive belt 106 is driven by a motor to rotate at high speed, pressing the paper tightly against the surface of the mandrel. The friction between the belt and the paper drives the paper forward. The paper spirally winds on the winding rod 103, with each turn overlapping the previous turn. The overlapping parts are bonded with glue. Multiple layers of paper are rolled up in sequence to form a tube wall. To reduce the friction between the paper and the fixed mandrel, the surface of the inner layer of paper is coated with a lubricating coating, so that the formed paper tube can slide smoothly on the winding rod 103. Because the belt is inclined, it generates two component forces when it rotates. One is perpendicular to the surface of the winding rod 103, pressing the paper tightly into shape. The other is along the axial direction of the winding rod 103, continuously pushing the formed paper tube out from the end of the mandrel, realizing continuous production without stopping the machine.

[0027] The output continuous paper tube is synchronously cut to a set length by a flying shear blade that moves at the same speed as the paper tube, thus completing the finished product cutting. This is existing technology and will not be described in detail here.

[0028] An electric push rod 302 is fixedly connected inside the fixed frame 301. The output end of the electric push rod 302 is fixedly connected to the bottom of the lifting frame 303. An inclined cover plate 305 is fixedly connected to the top of the lifting frame 303. The top of the inclined cover plate 305 has a slot 306 that mates with the pressing roller 204. A partition plate 307 is fixedly connected in the middle of the lifting frame 303, dividing the lifting frame 303 into a glue application chamber 304 and a material storage tank 308. Glue application roller assembly 0 04 is located inside the glue coating chamber 304. The top of the material storage tank 308 is equipped with a feed trough 309. The inside of the partition 307 is equipped with a glue inlet channel 310. Fans 311 are installed on both sides inside the glue coating chamber 304. The air outlet of the fan 311 is set towards the gap between the pressing roller 204 and the glue coating chamber 304 to form an air curtain on the side of the pressing roller 204. A sealing plate is slidably connected inside the glue inlet channel 310. The sealing plate is driven by an electric push rod.

[0029] The user raises the lifting frame 303 via the electric push rod 302, which then engages with the pressing roller 204. This allows the pressing roller 204 to pass through the slot 306 and enter the coating chamber 304, where it contacts and engages with the coating roller 401. When the user injects adhesive into the storage tank 308 through the feed chute 309, the adhesive inlet channel 310 is closed, allowing the user to store a certain amount of adhesive inside the storage tank 308. After injecting the adhesive, the user opens the adhesive inlet channel 310, allowing the adhesive to enter the coating chamber 401. Inside the coating cavity 304, the feed trough 309 is sealed when not in use. When the glue level inside the coating cavity 304 reaches the top of the glue inlet channel 310, the storage tank 308 is sealed. Under the action of air pressure difference, the glue no longer enters the coating cavity 304. When the glue level inside the coating cavity 304 drops, the glue re-enters through the glue inlet channel 310, making the glue level inside the coating cavity 304 stable. This not only allows for stable glue application to the coating roller 401 but also prevents the glue from submerging the pusher blade 606.

[0030] The inclined cover plate 305 is inclined to prevent paper scraps from entering the glue coating chamber 304. The fan 311 is started to inject gas into the glue coating chamber 304. The airflow is not strong, but it can form a weak air curtain on the side of the pressing roller 204 to prevent dust.

[0031] The paint roller 401 is rotatably connected inside the glue-applying cavity 304. A fixing block 402 is fixedly connected to the bottom of the glue-applying cavity 304. A paint brush 403 is fixedly connected to the top of the fixing block 402. The paint brush 403 is in contact with the paint roller 401. The height of the glue inlet channel 310 is greater than the top of the paint brush 403.

[0032] During the gluing process, the paper is conveyed by the pressing roller 204, which contacts the coating roller 401 as the paper passes through it. The coating roller 401 rotates, adhering the glue inside the gluing chamber 304 to the surface of the coating roller 401. The glue is then evenly coated onto the coating roller 401 by the coating brush 403, and then rotated to the paper surface to apply the glue to the paper.

[0033] The concentrator component 005 includes two symmetrical spiral scraper rods 501. The inner side of the spiral scraper rod 501 is provided with a scraper 502 that is in contact with the paint roller 401. The top of each spiral scraper rod 501 is fixedly connected to an active block 503. Electric push rods 505 are installed on both sides of the lifting frame 303. The output end of the electric push rod 505 is fixedly connected to a push rod 504. The push rod 504 is fixedly connected to the active block 503. The bottom of each spiral scraper rod 501 is fixedly connected to a driven block 506. The driven block 506 is slidably connected to a limiting rod 507 that is fixedly connected to the lifting frame 303.

[0034] After the coating roller 401 is coated with adhesive, it first passes through the focusing component 005. The doctor blade 502 then comes into contact with the surface of the coating roller 401, thereby scraping off the excess adhesive at both ends of the coating roller 401. This makes the area of ​​the remaining adhesive on the surface of the coating roller 401 match the width of the paper. By activating the electric push rod 505, the push rod 504 is extended or retracted. The push rod 504 drives the spiral scraper rod 501 to move through the active block 503, thereby adjusting according to the width of the paper. The driven block 506 at the bottom of the spiral scraper rod 501 slides outside the limiting rod 507, which facilitates the limiting of the doctor blade 502.

[0035] The coating thinning assembly 006 includes a C-shaped frame 601, which is fixedly connected to the inner side of the lifting frame 303. An electric push rod 602 is fixedly installed on the outer side of the C-shaped frame 601. A push plate 603 is fixedly connected to the output end of the electric push rod 602. A limiting groove 604 is opened on the inner side of the C-shaped frame 601. Limiting blocks 605 that slide in the limiting groove 604 are fixedly connected to both sides of the push plate 603. A pusher blade 606 that cooperates with the coating roller 401 is fixedly connected to the bottom of the push plate 603.

[0036] By activating the electric push rod 602, the push plate 603 is moved. The limiting block 605 on the side of the push plate 603 slides inside the limiting groove 604, thereby pushing the pusher blade 606 at the bottom of the push plate 603 closer to the coating roller 401. The user can adjust the distance between the pusher blade 606 and the coating roller 401 as needed, thereby adjusting the thickness of the adhesive coating.

[0037] The scraping assembly 007 includes a first scraping blade 701 and a second scraping blade 703. A first guide plate 702 is fixedly connected to the outer side of the first scraping blade 701, and a second guide plate 704 is fixedly connected to the outer side of the second scraping blade 703. A separating blade 705 is provided at the connection of the first scraping blade 701. A discharge conduit 706 is integrally fixedly connected to the outer side of the second scraping blade 703 and the second guide plate 704. A discharge trough 707 is provided on the side wall of the lifting frame 303. The discharge conduit 706 extends through the discharge trough 707 to the outer side of the lifting frame 303. A waste trough 708 is fixedly installed on the outer side of the fixed frame 301.

[0038] After the coating roller 401 is coated with adhesive, the width of the adhesive is controlled by the focusing component 005, and the thickness of the adhesive is adjusted by the thinning component 006. Then, the adhesive is applied to the paper. After the adhesive is applied, any paper scraps and excess adhesive adhering to the surface of the coating roller 401 will be cleaned by the scraping component 007. The coating roller 401 passes through the first scraping blade 701 and the second scraping blade 703, thereby removing impurities from the sides of the coating roller 401. After scraping, the impurities are prevented from entering the interior of the coating chamber 304 by the blocking of the first guide plate 702 and the second guide plate 704. The impurities are discharged through the discharge conduit 706 and collected through the waste trough 708.

[0039] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
