Description

Technical Field

[0001] This utility model relates to the field of kraft paper composite technology, and in particular to a synchronous correction and gluing device for double roll kraft paper composite. Background Technology

[0002] In the production of double-roll kraft paper lamination, the adhesive coating process is the core link that determines the lamination quality and production efficiency. The key lies in achieving uniform adhesive coating and precise lamination of the two layers of kraft paper. Currently, the mainstream technical solution for adhesive coating and lamination of double-layer kraft paper in the industry is to set up two independent coating units and complete the lamination process in batches. Specifically, this process typically involves first applying adhesive to one layer of kraft paper using the first coating unit. After the adhesive layer has initially cured or reached a specific viscosity, the second coating unit applies adhesive to the other layer of kraft paper according to process requirements. Finally, the two layers of kraft paper are bonded together by a pressing mechanism to form a composite board.

[0003] However, the two independent coating units need to be equipped with supporting components such as unwinding, gluing, drying, and traction. Sufficient operating space and material transfer distance must also be reserved between each component, which greatly increases the length and width of the entire production line. This places stringent requirements on the spatial layout of the production workshop. Limited factory space is often insufficient to accommodate such large equipment, limiting the possibility of technological upgrades and capacity increases. Secondly, the dual-unit equipment layout directly leads to a significant increase in production input costs. In addition to the equipment purchase costs of the two coating mechanisms themselves, the supporting power system, control system, drying system, etc., all need to be configured according to the dual-unit specifications. The initial investment cost of the equipment is more than 50% higher than that of the single-unit mechanism. In the subsequent production and operation process, the energy consumption, consumable replacement volume, and equipment maintenance workload of the dual-unit mechanism all increase exponentially, further increasing the production and operation costs and reducing the company's market competitiveness. Therefore, this application aims to solve the problem that the dual-unit independent coating mechanism requires two sets of supporting components and space reservation, resulting in a large equipment size, which is limited by the factory area and restricts the increase in production capacity. At the same time, its equipment investment and subsequent energy consumption, maintenance and other operating costs have increased significantly, weakening the company's market competitiveness. Therefore, a synchronous correction and gluing device for double-roll kraft paper lamination is proposed. Utility Model Content

[0004] To overcome the problem that dual independent coating mechanisms require two sets of unwinding, gluing, and drying components, and the reserved space for operation and transmission leads to a significant increase in production line size, which is difficult to accommodate in limited factory space, thus restricting technological upgrades and capacity increases. In addition, the initial investment cost of the equipment increases, and subsequent energy consumption, consumables, and maintenance costs double, driving up operating expenses and weakening the company's market competitiveness.

[0005] The technical solution of this utility model is as follows: a synchronous correction and gluing device for double-roll kraft paper lamination, comprising an anilox roller, a glue feeding assembly connected to the anilox roller, a support base provided at the lower end of the anilox roller, the support base being rotatably connected to the anilox roller, a glue storage tank connected to the support base, a connecting frame connected to one side of the glue storage tank, a connecting piece connected to the connecting frame, an industrial camera connected to the connecting piece, a fixing frame connected to the lower end of the connecting frame, a second motor connected to the fixing frame, a rotating disk connected to the output shaft of the second motor, a connecting roller frame connected to the rotating disk, and a guide roller rotatably connected to the connecting roller frame.

[0006] Preferably, a fixed scraper is connected to one side of the connecting frame;

[0007] A connecting strip is connected to one side of the glue storage tank, and a fixing rib is connected to the connecting strip.

[0008] Preferably, the lower end face of the connecting strip is connected to a support leg, the upper end face of the connecting strip is connected to a glue-collecting seat, and a mounting bracket is provided on one side of the glue-collecting seat, the mounting bracket being fixedly connected to the connecting strip.

[0009] Preferably, a fixed base is connected to the mounting frame, and a first pressing roller and a second pressing roller are rotatably connected to the fixed base.

[0010] Preferably, one end of the first pressing roller is connected to a second driving wheel, one end of the second pressing roller is connected to a second driven wheel, the teeth of the second driven wheel mesh with the teeth of the second driving wheel, a third motor is connected to the second driving wheel, and the third motor is fixedly connected to the fixed base.

[0011] Preferably, the glue feeding assembly includes a mounting plate connected to one end face of the glue storage tank, a lifting pump connected to the mounting plate, an input pipe connected to the input end of the lifting pump, the input pipe communicating with the inner cavity of the glue storage tank, an output pipe connected to the output end of the lifting pump, a connector rotatably connected to the output end of the output pipe, the connector being connected to the anilox roller, and the output pipe communicating with the anilox roller through the connector.

[0012] Preferably, a first driven wheel is connected to the outer surface of the connector, a fixing plate is connected to the connector, a first motor is connected to the fixing plate, a first driving wheel is connected to the output shaft of the first motor, and the teeth of the first driving wheel mesh with the teeth of the first driven wheel.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model uses vertically arranged anilox rollers to allow two layers of kraft paper to pass through from both sides. With the assistance of a fixed scraper, the glue carried in the mesh of the anilox rollers is simultaneously and evenly applied to the kraft paper on both sides, thereby achieving simultaneous glue application of double-sided kraft paper by a single roller. This integrated design significantly reduces the equipment footprint and lowers the manufacturing and operating costs of the entire device.

[0015] 2. By using inclined guide rollers, the kraft paper on both sides can be tilted inwards. This transforms the adverse effect of gravity into a controllable or even favorable one. The downward flow tendency of the glue due to gravity is directly countered and offset by the velocity component of the paper moving upwards along the inclined surface, achieving relative stability of the glue on the paper surface. This not only significantly improves the longitudinal uniformity of the glue coating and prevents the phenomenon of thinner top and thicker bottom, but also greatly shortens the free flow time and distance of the glue exposed to the outside by the inclined upward straight path. This allows the glue layer to enter the composite pressure roller quickly and stably, thereby using the system's own movement to dynamically balance physical defects, thus ensuring the quality of glue coating with simple mechanical means.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] refer to Figures 1-4 The structure shown is a synchronous correction and gluing device for double-roll kraft paper lamination, including an anilox roller 206, a glue feeding assembly connected to the anilox roller 206, a support base 207 provided at the lower end of the anilox roller 206, the support base 207 being rotatably connected to the anilox roller 206, a glue storage tank 101 connected to the support base 207, a connecting frame 301 connected to one side of the glue storage tank 101, a connecting piece 302 connected to the connecting frame 301, an industrial camera 303 connected to the connecting piece 302, a fixing frame 304 connected to the lower end of the connecting frame 301, a second motor 305 connected to the fixing frame 304, a rotating disk 306 connected to the output shaft of the second motor 305, a connecting roller frame 307 connected to the rotating disk 306, and a guide roller 308 rotatably connected to the connecting roller frame 307.

[0023] Among them, the second motor 305 is generally a stepper motor of model 17HS08-1004S used in conjunction with it;

[0024] The vertically arranged anilox roller 206 allows kraft paper to pass through both sides. With the assistance of a fixed doctor blade 309, the adhesive seeping from the mesh openings on the anilox roller 206 is coated onto the kraft paper on both sides. This allows for simultaneous coating of both sides of the kraft paper using a single roller, reducing the footprint of the entire coating device and significantly lowering operating costs. Simultaneously, the inclined guide roller 308 tilts the kraft paper inwards, mitigating the adverse effects of gravity. The transformation of the element into a controllable or even favorable factor means that the downward flow tendency of the glue due to gravity is directly countered and offset by the velocity component of the paper moving upward along the inclined surface, thus achieving relative stability of the glue on the paper surface. This not only significantly improves the longitudinal uniformity of the glue coating and prevents the phenomenon of thin top and thick bottom, but also greatly shortens the free flow time and distance of the glue exposed to the outside by the inclined upward straight path, allowing the glue layer to enter the composite pressure roller quickly and stably. In this way, the physical defects are dynamically balanced by the movement of the system itself, thus ensuring the quality of glue coating with simple mechanical means.

[0025] Meanwhile, the position of the kraft paper is monitored by the industrial camera 303. When a deviation occurs, the second motor 305 drives the rotating disk 306 to rotate. The rotating disk 306 adjusts the rotation of the connecting roller frame 307, so that the guide roller 308 on the connecting roller frame 307 can be deflected. This allows the kraft paper against the guide roller 308 to be corrected under the guidance of the deflected guide roller 308.

[0026] Furthermore, a fixed scraper 309 is connected to one side of the connecting bracket 301;

[0027] A connecting strip 401 is connected to one side of the glue storage tank 101, and a fixing rib plate 402 is connected to the connecting strip 401.

A mounting bracket 405 is provided on one side of the glue-collecting seat 404, and the mounting bracket 405 is fixedly connected to the connecting strip 401.

[0029] Furthermore, a fixed seat 501 is connected to the mounting bracket 405, and a first pressing roller 502 and a second pressing roller 503 are rotatably connected to the fixed seat 501.

[0030] Furthermore, one end of the first pressing roller 502 is connected to the second driving wheel 504, and one end of the second pressing roller 503 is connected to the second driven wheel 505. The teeth of the second driven wheel 505 mesh with the teeth of the second driving wheel 504. A third motor 506 is connected to the second driving wheel 504, and the third motor 506 is fixedly connected to the fixed base 501.

[0031] Among them, the third motor 506 is generally a stepper motor of model 17HS08-1004S used in conjunction with it.

[0032] Furthermore, the glue feeding assembly includes a mounting plate 102 connected to one end face of the glue storage tank 101. A lift pump 103 is connected to the mounting plate 102. An input pipe 104 is connected to the input end of the lift pump 103. The input pipe 104 is connected to the inner cavity of the glue storage tank 101. An output pipe 105 is connected to the output end of the lift pump 103. A connector 201 is rotatably connected to the output end of the output pipe 105. The connector 201 is connected to the anilox roller 206. The output pipe 105 is connected to the anilox roller 206 through the connector 201.

[0033] Furthermore, a first driven wheel 205 is connected to the outer surface of the connector 201, a fixing plate 202 is connected to the connector 201, a first motor 203 is connected to the fixing plate 202, a first driving wheel 204 is connected to the output shaft of the first motor 203, and the teeth of the first driving wheel 204 mesh with the teeth of the first driven wheel 205.
