Description

Technical Field

[0001] This invention relates to the field of cardboard production technology, specifically to an internal sizing device for food cardboard paste with adjustable aluminum sulfate dosage. Background Technology

[0002] In the production of food-grade sizing agents, aluminum sulfate is used as an internal sizing agent, and the precise control of its dosage directly affects the quality and stability of the product. Traditional equipment often relies on manual feeding or fixed-ratio addition, which suffers from inflexible adjustments, susceptibility to errors, and difficulty in adapting to the dynamic requirements of different processes for aluminum sulfate dosage. In addition, existing mixing devices are prone to uneven distribution and low mixing efficiency during the feeding process, affecting the uniformity of the sizing effect. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a reasonably designed and easy-to-use food slurry internal sizing device with adjustable aluminum sulfate dosage. This device achieves precise adjustment and automated feeding of aluminum sulfate dosage, effectively improving mixing uniformity and production efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: it comprises a mixing tank, supporting legs, a feeding tank, and a feed pipe. Several supporting legs are fixed at equal angles on the outer bottom wall of the mixing tank. A feeding tank is provided on one side of the top wall of the mixing tank, and the other side of the mixing tank is connected to an external pumping pump via the feed pipe. It also includes: The mounting plate is fixedly installed on one side of the top wall inside the mixing tank, and a stirring mechanism is provided on one side of the mounting plate. The stirring mechanism is connected to the top wall of the mixing tank. The fixing plate is fixed on the side wall of the mounting plate away from the stirring mechanism. The rectangular groove on the fixing plate is fitted onto the discharge end of the feeding barrel on the lower side. The bottom wall of the discharge end of the feeding barrel abuts against the feeding pipe, and the feeding pipe is connected to the fixing plate through a reciprocating mechanism. The insertion tube is movably inserted into the feeding tube. A sealing cap abuts against the bottom wall of the insertion tube. The protrusion on the rear side of the sealing cap is screwed to the convex ring at the bottom end of the insertion tube via a shaft. A quantitative adjustment mechanism is fixed to the bottom wall of the fixed plate and is connected to the insertion tube and the sealing cap. A discharge pump is fixed to one side of the outer ring wall of the mixing tank, and the feed end of the discharge pump is connected to the lower side of the inside of the mixing tank through a pipe. Through the above technical solution, the material is transported to the mixing tank by an external pump. Aluminum sulfate is loaded into the feeding tank. According to the required amount, the position of the insertion tube is adjusted by a quantitative adjustment mechanism to ensure that the amount filled into the feeding tube each time is the same and meets the requirements. Then, the feeding tube is driven to move back and forth by a reciprocating mechanism. During the reciprocating movement, the sealing cover is opened and closed alternately, so that aluminum sulfate falls into the mixing tank alternately. The mixing is carried out by a stirring mechanism. After the mixing is completed, the material is discharged to the next process by a discharge pump.

[0005] As a further improvement of the present invention, the stirring mechanism includes: A stirring rod is installed inside a mixing tank. Several stirring frames are fixed at equal angles on the lower end of the stirring rod, and the upper end of the stirring rod is inclined. The collar consists of two collars, which are symmetrically and movably fitted onto the upper end of the stirring rod. The collars are fixed to the mounting plate by a support rod. A hemisphere is fitted and fixed on the stirring rod between the two collars, and the outer arc surface of the hemisphere is set to abut against the collar. The drive motor is fixed to the outer top wall of the mixing tank, and a connecting shaft is fixed on the output shaft of the drive motor. The connecting shaft passes through the mixing tank and is suspended inside the mixing tank. A connecting plate is fixed to one side of the outer ring wall of the connecting shaft, and one side of the inclined side wall of the connecting plate is connected to the top of the stirring rod. With the above technical solution, the drive motor is started, and the drive motor drives the connecting plate to rotate through the connecting shaft. The connecting plate drives the stirring rod to rotate in an inclined position, and the stirring rod drives the stirring frame to rotate, thereby stirring the material in the mixing tank. During the stirring process, the hemisphere on the stirring rod abuts against the collar, thus ensuring the stability and smoothness of the stirring rod when it rotates.

[0006] As a further improvement of the present invention, several stirring blades are fixed at equal numbers and angles on the middle end of the stirring rod, and the stirring blades are located between the lower collar and the stirring frame; this can increase the stirring area.

[0007] As a further improvement of the present invention, a connecting pipe is sleeved on the top end of the stirring rod and screwed to it through a bearing. The connecting pipe is fixedly connected to the connecting plate. A connecting ring is sleeved and fixed on the stirring rod at the position between the two hemispheres. A driven gear is sleeved on the outside of the connecting ring. A driving gear meshes with one side of the driven gear. A connecting rod is inserted and fixed in the center of the driving gear. The top end of the connecting rod is screwed to the top wall of the mixing tank through a bearing. The end of the connecting rod located inside the top wall of the mixing tank is connected to the connecting shaft through a synchronous wheel transmission assembly. With the above technical solution, when the connecting shaft rotates, it drives the connecting rod to rotate, which in turn drives the driving gear to rotate. The driving gear then drives the driven gear to rotate, which in turn drives the connecting ring to rotate. The connecting ring then drives the stirring rod to rotate, thereby improving the mixing effect.

[0008] As a further improvement of the present invention, a reinforcing plate is sleeved on the connecting rod and screwed to it by a bearing, and the reinforcing plate is fixedly connected to the inner wall of the mixing tank; this can increase the stability of the connecting rod when it rotates.

[0009] As a further improvement of the present invention, the reciprocating mechanism includes: The reciprocating plate is sleeved and fixed on the feeding pipe. The reciprocating plate is movably arranged in a rectangular groove on the fixed plate, and the reciprocating plate is engaged with the bottom wall of the feeding barrel. A reciprocating motor is fixed on the upper surface of a fixed plate. A drive disk is fixed on the output shaft of the reciprocating motor and is movably embedded in a circular groove inside the fixed plate. A toggle lever is fixed to one side of the lower surface of the drive disc and is movably inserted into the oblong hole on the reciprocating plate. Using the above technical solution, the reciprocating motor is started, which drives the drive plate to rotate. During the rotation of the drive plate, the reciprocating plate moves back and forth through the cooperation of the lever and the oblong hole.

[0010] As a further improvement of the present invention, the quantitative adjustment mechanism includes: Positioning plates, there are two positioning plates, which are symmetrically arranged on both sides of the feeding tube. The positioning plates are fixed on the bottom wall of the fixed plate. Movable plates are sleeved on the outer side of each positioning plate, and the lower side of the movable plates is located on both sides of the lower end of the insertion tube. Insert plates, there are two insert plates, and they are respectively fixed on the lower side of the movable plate adjacent to the side wall of the insertion tube. The insert plates are movably inserted into the slots on the outer ring wall of the convex ring at the lower end of the insertion tube. Two electric push rods are fixed symmetrically on the lower surface of the fixing plate, and the piston end of the electric push rod is fixed on the upper surface of the corresponding insert plate. The baffle abuts against the lower side of the sealing cover, and the two sides of the upper surface of the baffle are respectively fixedly connected to the lower sides of the two movable plates. Using the above technical solution, the amount of material added each time is adjusted according to the required ratio. At this time, the electric push rod is activated, which drives the insert plate to move, and the insert plate drives the insert tube to move. The amount of material added each time is adjusted by adjusting the space between the insert tube and the feeding tube, thereby ensuring that the amount of material added each time is the same.

[0011] As a further improvement of the present invention, limit blocks are fixed on both the front and rear side walls of the positioning plate, and the limit blocks are slidably disposed in the grooves on the front and rear inner walls of the movable plate. The above technical solution can prevent the movable plate from falling off the positioning plate.

[0012] As a further improvement of the present invention, a rotating motor is fixed to the upper side of the inside of the feeding barrel by a support plate, a crushing rod is fixed to the output shaft of the rotating motor, the crushing rod is suspended on the lower side of the inside of the feeding barrel, and several crushing blades are fixed on the crushing rod from top to bottom at equal angles. Several unblocking rods are fixed at equal angles at the lower end of the outer ring wall of the crushing rod, and the unblocking rods are located inside the bottom end of the feeding barrel. With the above technical solution, when in use, the rotating motor is started, which drives the crushing rod to rotate. The crushing rod drives the crushing blades and the unblocking rod to rotate. The crushing blades crush the aluminum sulfate, which facilitates the subsequent mixing. The unblocking rod can prevent the feeding bucket from becoming blocked.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The quantitative adjustment mechanism driven by the electric push rod can accurately control the position of the insertion tube in the feeding tube, thereby flexibly adjusting the amount of aluminum sulfate added at one time, ensuring accurate and stable feeding ratio, and meeting different process requirements; 2. The stirring rod rotates on its own axis while revolving around the sun, which is achieved through gear transmission, forming a composite three-dimensional stirring mode. This greatly increases the stirring area and the degree of turbulence, enabling aluminum sulfate and slurry to be mixed quickly and evenly. 3. The reciprocating mechanism drives the feeding pipe to move back and forth regularly. Combined with the alternating opening and closing of the sealing cover, it realizes the intermittent and automated feeding of aluminum sulfate from the feeding tank to the mixing tank, reducing manual operation and ensuring the continuity of the process. 4. A crushing and unblocking mechanism consisting of crushing blades and unblocking rods is installed in the feeding hopper, which can effectively crush aluminum sulfate that is prone to caking and prevent the discharge port from being blocked, thus ensuring the smooth flow of materials and the quality of mixing from the source.

[0030] In using this invention, the material is conveyed to the mixing tank 1 via an external pump. Aluminum sulfate is placed in the feeding tank 3. The rotating motor 22 is started, which drives the crushing rod 23 to rotate. The crushing rod 23 drives the crushing blade 24 and the unblocking rod 25 to rotate. The crushing blade 24 crushes the aluminum sulfate, facilitating subsequent mixing. The unblocking rod 25 prevents blockage in the feeding tank 3.

The reciprocating plate 9-1 drives the feeding tube 8 to move back and forth. During the reciprocating movement, the sealing cover 11 is opened and closed alternately, so that aluminum sulfate falls into the mixing tank 1 alternately. Start the drive motor 6-5. The drive motor 6-5 drives the connecting plate 6-7 to rotate via the connecting shaft 6-6. The connecting plate 6-7 drives the stirring rod 6-1 to rotate at an angle. The stirring rod 6-1 drives the stirring frame 6-2 to rotate, thereby stirring the material in the mixing tank 1.

When the connecting shaft 6-6 rotates, it drives the connecting rod 19 to rotate. The connecting rod 19 drives the drive gear 18 to rotate. The drive gear 18 drives the driven gear 17 to rotate. The driven gear 17 drives the connecting ring 16 to rotate. The connecting ring 16 drives the stirring rod 6-1 to rotate, thereby improving the mixing effect. After the mixing is completed, the material is discharged to the next process via the discharge pump 13.

[0031] Compared with the prior art, the beneficial effects of this specific embodiment are as follows: 1. The quantitative adjustment mechanism 12 driven by the electric push rod 12-4 can accurately control the position of the insertion tube 10 in the feeding tube 8, thereby flexibly adjusting the amount of aluminum sulfate added at one time, ensuring accurate and stable feeding ratio, meeting different process requirements, and significantly improving product quality consistency and batch stability. 2. The stirring rod 6-1 rotates on its own axis while revolving around the sun, forming a composite three-dimensional stirring mode. This greatly increases the stirring area and the degree of turbulence, enabling aluminum sulfate and slurry to mix quickly and evenly, effectively shortening the production cycle time and reducing unit energy consumption costs. 3. The reciprocating mechanism 9 drives the feeding pipe 8 to reciprocate regularly. In conjunction with the alternating opening and closing of the sealing cover 11, it realizes the intermittent and automated feeding of aluminum sulfate from the feeding tank 3 to the mixing tank 1, which reduces manual operation and ensures the continuity of the process, and greatly improves the overall production efficiency and the level of equipment automation. 4. A crushing and unblocking mechanism consisting of crushing blades 24 and unblocking rods 25 is installed in the feeding hopper 3. This mechanism can effectively crush aluminum sulfate that is prone to caking and prevent blockage of the feed inlet. It ensures smooth material flow and mixing quality from the source and completely eliminates the problem of downtime and cleaning caused by caking and blockage.
