Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, specifically to a homogenizing mixing device for preparing sizing agents for decorative paper surfaces. Background Technology

[0002] In the field of decorative paper production, the function of this homogenizing mixing device is to achieve microscopic homogenization of the components of the sizing agent by enhancing shearing and precise temperature control.

[0003] The device consists of a multi-stage shearing module, a constant temperature control system, a precision feeding unit, an online monitoring component, and a buffer discharge mechanism. The metering pump injects the raw materials into the mixing chamber according to the formula. The high-speed dispersion disc initially breaks up the agglomerated particles, and the colloid mill further grinds them to microscopic homogeneity. The jacket and the inner coil work together to control the temperature. The online monitoring component provides real-time data feedback. After the material meets the standards, it is discharged into the transfer tank for buffering and is used in subsequent coating processes.

[0004] However, the above-mentioned equipment has obvious shortcomings in use. Traditional mixing devices rely only on a single set of stirring paddles at the top for longitudinal stirring or a single set of propellers at the bottom for conveying, which cannot cover the edges and corners of the mixing tank and easily form mixing dead zones. In view of this, we propose a homogenization mixing device for the preparation of sizing agents for decorative paper surfaces. Utility Model Content

[0005] The purpose of this invention is to provide a homogenizing mixing device for preparing sizing agents for decorative paper surfaces, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A homogenizing mixing device for preparing a decorative paper surface sizing agent includes a support frame, a stirring tank fixedly mounted on the support frame, and a stirring assembly disposed on the stirring tank. The stirring assembly includes: A cylindrical container is fixedly installed at the bottom of a mixing tank. An auxiliary material pipe and a discharge pipe are fixedly installed on the cylindrical container. A bottom motor is fixedly installed at the bottom of the cylindrical container, and a vertical rod is fixedly installed at the output end of the bottom motor. The auger propeller is fixedly installed on the vertical rod. A cover is snapped onto the mixing tank. A vibrating device is fixedly installed on the cover. A transmission rod is fixedly installed at the output end of the vibrating device. A mounting bracket is fixedly installed on the cover. A servo motor is fixedly installed on the mounting bracket. A straight rod is fixedly installed at the output end of the servo motor. A flat paddle and a stirring paddle are fixedly installed on the straight rod.

[0007] In a further embodiment, multiple sets of the auxiliary material pipe, vibration device, transmission rod, and flat paddle are provided.

[0008] In a further embodiment, the stirring paddle is positioned below multiple sets of horizontal paddles, and the stirring paddle and horizontal paddles are positioned between multiple sets of transmission rods.

[0009] In a further embodiment, the auger paddle is located inside the cylinder, and the cylinder and auger paddle are located below the stirring paddle. Valves are installed on both the auxiliary material pipe and the discharge pipe.

[0010] In a further embodiment, the mixing tank is provided with an auxiliary component, which includes a mounting plate. The mounting plate is fixedly mounted on the mixing tank, and a power motor is fixedly mounted on the mounting plate. A short rod is fixedly mounted on the output end of the power motor, and a propeller is fixedly mounted on the short rod.

[0011] In a further embodiment, the mounting plate, power motor, short rod, and propeller are provided in multiple sets.

[0012] In a further embodiment, the propeller is disposed inside the mixing tank, and the propeller is positioned diagonally below the mixing paddle.

[0013] Compared with the prior art, this utility model provides a homogenizing mixing device for preparing sizing agents for decorative paper surfaces, which has the following beneficial effects: 1. This homogenizing mixing device for preparing decorative paper sizing agent is equipped with a stirring component to meet the homogenization requirements of decorative paper sizing agent preparation. This component, in conjunction with a servo motor, drives a straight rod to rotate a flat paddle and a stirring paddle. The flat paddle stirs the upper layer of raw materials to form a horizontal circulation, while the stirring paddle performs longitudinal shearing on the middle layer of raw materials. At the same time, the bottom motor drives an auger paddle to rotate inside the cylinder, conveying the bottom raw materials upward to prevent sedimentation. Multiple sets of auxiliary material pipes can accurately add various additives. Valves control the feeding rate, and a vibration device drives the raw materials to vibrate through a transmission rod, breaking up raw material agglomeration.

[0014] 2. The homogenizing mixing device for preparing the surface sizing agent of decorative paper, in order to ensure the consistency of the finished product quality, is equipped with an auxiliary component. This component works with a power motor to drive a short rod to rotate a propeller. The propeller is located obliquely below the stirring paddle, stirring the deposited raw materials at the bottom and edge of the mixing tank upwards, forming a convection circulation with the middle layer of the stirring paddle, eliminating mixing dead zones. The high-speed rotation of the propeller generates local turbulence, which enhances the fusion reaction between the additives and the main material. Attached Figure Description

[0019] Please see Figures 1-5 This utility model provides a technical solution: A homogenizing mixing device for preparing a decorative paper surface sizing agent includes a support 1, on which a mixing tank 2 is fixedly installed.

[0020] In one embodiment of this utility model, a stirring assembly 3 is provided on the stirring tank 2. The stirring assembly 3 includes a cylinder 31, which is fixedly installed at the bottom of the stirring tank 2. An auxiliary material pipe 32 and a discharge pipe 33 are fixedly installed on the cylinder 31. A bottom motor 34 is fixedly installed at the bottom of the cylinder 31. A vertical rod 35 is fixedly installed at the output end of the bottom motor 34. An auger paddle 36 is fixedly installed on the vertical rod 35. A cover 37 is snapped onto the stirring tank 2. A vibration device 38 is fixedly installed on the cover 37. A transmission rod 39 is fixedly installed at the output end of the vibration device 38. A mounting bracket 310 is fixedly installed on the cover 37. 7. A servo motor 311 is fixedly installed on the mounting bracket 310. A straight rod 312 is fixedly installed on the output end of the servo motor 311. A flat paddle 313 and an agitator 314 are fixedly installed on the straight rod 312. Multiple sets of auxiliary material pipe 32, vibration device 38, transmission rod 39 and flat paddle 313 are provided. The agitator 314 is located below the multiple sets of flat paddles 313. The agitator 314 and flat paddle 313 are located between the multiple sets of transmission rods 39. The auger paddle 36 is located inside the cylinder 31. The cylinder 31 and the auger paddle 36 are located below the agitator 314. Valves are provided on both the auxiliary material pipe 32 and the discharge pipe 33.

[0021] In this embodiment, before preparation, the lid 37 of the mixing tank 2 is opened, and the main sizing agents such as starch and polyvinyl alcohol are added into the mixing tank 2 in proportion. The lid 37 is then closed to ensure a sealed reaction process. Subsequently, according to the formula requirements, the feeding rate is adjusted through the valve on the auxiliary material pipe 32 to deliver various additives such as thickeners and waterproofing agents into the cylinder 31. After being buffered by the cylinder 31, the additives are evenly introduced into the mixing tank 2 to avoid uneven reaction caused by excessively high local additive concentrations. Then, the servo motor 311 is started to drive the straight rod 312 to rotate, which drives the flat paddle 313 and the stirring paddle 314 to move synchronously. The multiple sets of flat paddles 313 in the upper layer stir the raw materials in a horizontal rotation manner, forming a horizontal circulation along the inner wall of the mixing tank 2, which quickly melts the surface raw materials with the newly added additives. The mixing paddle 314 in the lower layer acts on the middle layer of raw materials in a longitudinal shearing manner, breaking up the raw material agglomerates and allowing the main material and additives to initially combine at the molecular level. At the same time, the bottom motor 34 in the bottom cylinder 31 of the mixing tank 2 starts, driving the auger paddle 36 to rotate through the vertical rod 35, transporting the high-density raw materials that are easy to settle at the bottom of the mixing tank 2 upward to the middle layer mixing area, where they merge with the mixing flow formed by the horizontal paddle 313 and the mixing paddle 314, completely avoiding the concentration difference between the upper and lower layers caused by raw material sedimentation. Meanwhile, for some raw materials with high viscosity and easy agglomeration, multiple sets of vibration devices 38 on the cover 37 start synchronously, transmitting high-frequency vibration to the raw materials in the tank through the transmission rod 39, dispersing the agglomerated particles of the raw materials, creating favorable conditions for the homogenization and mixing of the mixing components.

[0022] In one embodiment of this utility model, an auxiliary component 4 is provided on the mixing tank 2. The auxiliary component 4 includes a mounting plate 41, which is fixedly mounted on the mixing tank 2. A power motor 42 is fixedly mounted on the mounting plate 41. A short rod 43 is fixedly mounted on the output end of the power motor 42. A propeller 44 is fixedly mounted on the short rod 43. Multiple sets of mounting plate 41, power motor 42, short rod 43 and propeller 44 are provided. The propeller 44 is located inside the mixing tank 2 and is located diagonally below the mixing paddle 314.

[0023] In this embodiment, the motor 42 on the mounting plate 41 is started, driving the short rod 43 and the propeller 44 to rotate at high speed. The propeller 44, located diagonally below the stirring paddle 314, generates an upward thrust, stirring the deposited raw materials at the bottom corners of the mixing tank 2 and the raw materials attached to the inner wall upward, pushing them to the middle mixing zone to merge with the main mixing flow, completely eliminating the mixing dead zones. At the same time, the high-speed rotation of the propeller 44 will form local turbulence in the tank. The strong disturbance generated by the turbulence can break the interfacial tension between the main material and the additives, accelerating the fusion reaction between the two. Especially for the difficult-to-dissolve additives, the turbulence can significantly improve their dispersion rate, ensuring that each part of the raw material can reach a uniform mixing state.

[0024] In this application, all electrical components are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the bottom motor 34, vibration device 38, servo motor 311, and power motor 42.

The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. In addition, the standard parts are all conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art.
