Description

Technical Field

[0001] The present application relates to the field of water reducing agent production equipment, and in particular to a water reducing agent packaging mechanism. Background Art

[0002] A water reducer is a concrete admixture that reduces mixing water consumption while maintaining a relatively constant concrete slump. When added to the concrete mix, it disperses cement particles, improving workability and reducing water consumption per unit of concrete, or cement usage per unit of concrete, thereby conserving cement.

[0003] After the water reducer is produced, a large amount of water reducer needs to be evenly packaged and then packaged.

[0004] At present, in the process of packaging a large amount of water reducer, the prepared water reducer is first placed in a packaging barrel. A discharge port is provided at the lower part of the packaging barrel, and a cover is provided at the discharge port. The staff controls the cover to open and close the discharge port, thereby discharging the water reducer in the packaging barrel.

[0005] With respect to the above-mentioned related technologies, the inventors believe that since the workers control the discharge amount of the water reducer based on the opening and closing of the cover and their work experience when packaging the water reducer, the problem of uneven packaging of the water reducer is prone to occur. Summary of the Invention

[0006] In order to accurately control the discharge amount of water reducer from the filling barrel and evenly fill a large amount of water reducer, the present application provides a water reducer filling mechanism.

[0007] The water reducing agent packaging mechanism provided in this application adopts the following technical solution:

[0008] The packaging barrel is provided with a discharge port at the bottom, and the packaging mechanism also includes a fixed shell fixedly arranged at the discharge port, a packaging box slidably arranged in the fixed shell, and a driving member fixedly arranged on the fixed shell, the driving end of the driving member is fixedly connected to the packaging box and drives the packaging box to reciprocate in the fixed shell; the discharge port is communicated with the interior of the fixed shell, and the side of the fixed shell opposite to the discharge port is a closed side, the length of the packaging box is equal to the length of the closed side of the fixed shell, and the packaging box is provided with two packaging spaces, the two packaging spaces can be communicated with the discharge port respectively, and a sealing plate is formed between the two packaging spaces, when the packaging space is misaligned with the discharge port and is located on the closed side, the sealing plate closes the discharge port, and after the packaging space is misaligned with the closed side, the lower part of the packaging space is communicated with the lower part of the fixed shell.

[0009] By adopting the above technical solution, after the water reducer enters the filling box through the discharge port, the filling amount of the water reducer is determined. Driven by the driving member, the filling box runs stably and reciprocatingly in the fixed shell, so that the two filling spaces continuously discharge the discharged water reducer in a quantitative manner, thereby achieving effective filling of a large amount of water reducer located inside the filling barrel.

[0010] Optionally, two sub-packaging conveyors are fixedly provided at the lower part of the fixed shell, and the two sub-packaging conveyors are used to respectively receive the water reducer discharged from the two sub-packaging spaces.

[0011] By adopting the above technical solution, the subpackaging conveyor can regularly convey the evenly discharged water reducer, thereby facilitating subsequent water reducer packaging work.

[0012] Optionally, a rotating shaft is provided in the filling barrel, and a conveying blade for discharging the water reducing agent to the discharge port is installed on the rotating shaft.

[0013] By adopting the above technical solution, the conveying blades can ensure that the water reducer in the sub-filling barrel is continuously discharged through the discharge port, thereby improving the stability and consistency of the discharge amount of the water reducer in the sub-filling barrel.

[0014] Optionally, stirring blades are also installed on the rotating shaft.

[0015] By adopting the above technical solution, the stirring blades continuously stir the water reducer to be discharged from the sub-filling barrel, reducing the possibility of the water reducer in the sub-filling barrel being squeezed and adhering to the inner wall, thereby maintaining the water reducer with good fluidity before discharge, which is conducive to the uniform discharge of the water reducer from the sub-filling barrel.

[0016] Optionally, an impact assembly is installed on the outer wall of the filling barrel, and the impact assembly includes an impact plate that can fit against the outer wall of the filling barrel, a buffer member with a buffer end fixedly connected to the side of the impact plate facing away from the filling barrel, a mounting plate fixedly connected to the end of the buffer member away from the impact plate, and baffles fixed and spaced apart on the outer wall of the filling barrel, the impact plate can move between the two baffles, and a driving assembly for driving the impact assembly is fixedly connected to the side of the mounting plate facing away from the buffer member.

[0017] By adopting the above technical solution, the baffle limits the movement range of the impact plate, thereby improving the stability of the impact plate's impact on the sub-filling barrel. The impact plate impacts the sub-filling barrel under the drive of the driving component, and the barrel wall of the sub-filling barrel vibrates under the impact, which can shake off the water reducer attached to the inner wall of the sub-filling barrel, thereby further improving the smoothness of the water reducer when discharged from the sub-filling barrel.

[0018] Optionally, the buffer component includes a shell fixedly set on the mounting plate, a limit plate movably set inside the shell, a spring set in the shell and in a naturally extended state, and a telescopic rod with one end movably passed through the shell and fixedly connected to the impact plate and the other end movably passed through the mounting plate, and the telescopic rod is fixedly connected to the limit plate.

[0019] By adopting the above technical solution, the overall structure of the buffer is simple, and a good buffering transition can be formed between the impact plate and the drive assembly. While the impact plate effectively impacts the filling barrel, the possibility of the impact plate causing damage to the outer wall of the filling barrel can be reduced.

[0020] Optionally, the driving assembly includes a driving motor fixedly mounted on the outer wall of the filling barrel and spaced apart from the filling barrel, an eccentric disk rotatably mounted on the output end of the driving motor, and a driving connecting rod rotatably connected to the eccentric disk, wherein the driving connecting rod is hinged to the mounting plate.

[0021] By adopting the above technical solution, the driving component is simple in composition and has the characteristics of easy installation and maintenance and high operational stability, and can stably drive the impact component to impact the filling barrel.

[0022] Optionally, a support rod is fixed on the driving connecting rod, and universal wheels are installed on the support rod, the mounting plate and the lower part of the impact plate.

[0023] By adopting the above technical solution, the friction between the support rod, the mounting plate and the fixing plate during the impact process is reduced, and the running smoothness of the impact component and the driving component is improved.

[0024] Optionally, the driving assembly further comprises a fixing plate fixedly arranged on the outer wall of the filling barrel, and the universal wheel is slidingly arranged on the fixing plate.

[0025] By adopting the above technical solution, the fixing plate provides stable support for components such as the drive motor, the mounting plate and the impact plate.

[0026] In summary, this application includes at least one of the following beneficial technical effects:

[0027] 1. By setting up the sub-packaging components, the sub-packaging amount of the water reducer is determined. The sub-packaging box runs stably and reciprocatingly in the fixed shell, so that the two sub-packaging spaces continuously discharge the water reducer in a quantitative manner, thereby achieving effective sub-packaging of a large amount of water reducer located inside the sub-packaging barrel.

[0028] 2. By setting the rotating shaft and conveying blades, the conveying blades can ensure that the water reducer in the sub-filling barrel is continuously discharged through the discharge port, thereby improving the stability and consistency of the discharge amount of the water reducer in the sub-filling barrel.

[0029] 3. By setting the stirring blades, the possibility of the water reducer in the sub-filling barrel being squeezed and attached to the inner wall is reduced, thereby maintaining the water reducer with good fluidity before discharge, which is conducive to the uniform discharge of the water reducer from the sub-filling barrel.

[0034] The following is combined with Figure 1-3 , further explain this application in detail.

[0035] The present application embodiment discloses a water reducing agent packaging mechanism, referring to Figure 1 It includes a filling barrel 1 with a discharge port at the bottom, a filling assembly 2 fixedly arranged on the filling barrel 1 and located below the discharge port, two filling conveyors 3 fixedly arranged at the bottom of the filling assembly 2, a driving assembly 4 fixedly arranged on the outer wall of the filling barrel 1, and an impact assembly 5 arranged on the driving assembly 4 for impacting the filling barrel 1.

[0036] Reference Figure 1A supporting leg 11 is vertically fixed to the lower part of the filling barrel 1. There are at least three supporting legs 11, which suspend the filling barrel 1 above the ground. A stirring motor 12 is also provided on the top of the filling barrel 1. The output shaft of the stirring motor 12 is connected to a rotating shaft 13 via a coupling. Stirring blades 14 and conveying blades 15 are fixedly provided along the axis of the rotating shaft 13 and in sequence from top to bottom. The conveying blades 15 are located in the discharge port. The stirring blades 14 and the conveying blades 15 rotate in opposite directions. When the stirring motor 12 drives the rotating shaft 13 to rotate, the water reducer in the filling barrel 1 can be flipped from bottom to top under the action of the stirring blades 14, while the conveying blades 15 discharge the water reducer in the discharge port toward the discharge port.

[0037] Reference Figure 1 The packaging component 2 includes a fixed shell 21 fixedly arranged at the lower part of the discharge port, a packaging box 22 slidably arranged in the fixed shell 21, and a driving member 23 fixedly arranged on the fixed shell 21 and fixedly connected to the packaging box 22 at the output end.

[0038] Reference Figure 1 The upper portion of the fixed shell 21 has a circular opening 211 of the same size as the discharge port. The discharge port communicates with the interior of the fixed shell 21 through the opening 211, and the side of the fixed shell 21 opposite the discharge port is closed. The lower portion of the fixed shell 21 has two spaced-apart notches 212 for discharging the water reducer, with the closed side of the fixed shell 21 located between the two notches 212.

[0039] Reference Figure 1 The length of the packaging box 22 is equal to the length of the closed side of the fixed shell 21, and the midpoint of the closed side is aligned with the center of the opening 211, thereby completely sealing the packaging box 22 and facilitating subsequent packaging operations. The packaging box 22 is provided with two packaging spaces 221, which are spaced apart from each other and a sealing plate 222 is formed between the two packaging spaces 221.

[0040] by Figure 1 For example, when the left-side packaging space 221 corresponds to the discharge port, the right-side packaging space 221 corresponds to the right-side notch 212. When the left-side packaging space 221 completely corresponds to the discharge port, the outer wall of the right-side packaging space 221 abuts against the inner wall of the fixed shell 21. If the right-side packaging space 221 is full of water reducer, when the right-side packaging space 221 is connected to the right-side notch 212, the water reducer in the right-side packaging space 221 can be quantitatively packaged.

[0041] When the left sub-packaging space 221 is completely corresponding to the discharge port, the left sub-packaging space 221 is filled with water reducer, and then the left sub-packaging space 221 needs to be moved to the left and correspond to the left notch 212, so that the quantitative sub-packaging of the water reducer can be completed to the left. In the process of the sub-packaging box 22 moving from the right to the left, the left sub-packaging space 221 is always located on the closed side of the fixed shell 21, so that the water reducer located in the sub-packaging space 221 will not leak. When the left sub-packaging space 221 is completely corresponding to the left notch 212, the outer wall of the left sub-packaging space 221 abuts against the inner wall of the fixed shell 21, and now the right sub-packaging space 221 is completely corresponding to the discharge port. The sealing plate 222 can temporarily block the discharge port during the left-right movement of the sub-packaging box 22.

[0042] The two subpackaging conveyors 3 are respectively located below the two gaps 212. When the subpackaging space 221 filled with water reducer corresponds to the corresponding gap 212 and the water reducer is discharged, it can accurately fall onto the corresponding subpackaging conveyor 3, which is conducive to the transportation of a large amount of water reducer and facilitates the subsequent packaging of a large amount of water reducer.

[0043] Reference Figure 2 The driving member 23 includes two fixed seats 231 spaced apart and mounted on the same side outer wall of the fixed housing 21, screws 232 rotatably mounted on the two fixed seats 231, a motor 233 mounted on the outer wall of the fixed housing 21, and a connecting block 234 threadedly connected to the screws 232. Gears are mounted on the output shaft of the motor 233 and one end of the screw 232, respectively, and the two gears mesh. A strip-shaped hole is defined in the outer wall of the fixed housing 21 for the connecting block 234 to extend into. The lengths of the screws 232, the fixed housing 21, and the strip-shaped hole are all parallel to each other. The connecting block 234 is located within the strip-shaped hole and is fixedly connected to the side wall of the packaging box 22. A travel switch (not shown) is mounted on opposite inner walls of the fixed housing 21. The two travel switches are electrically connected to the motor 233. When the two travel switches are turned on, opposite positive and negative currents are supplied to the motor 233. By controlling the positive and negative poles of the power supply to the motor 233, the screw 232 can be rotated forward and reverse, thereby driving the packaging box 22 to move within the fixed housing 21. The screw 232 can stably control the regular reciprocating movement of the packaging box 22, thereby evenly dispensing the water reducer.

[0044] Combine Figure 1 and Figure 3The driving assembly 4 includes a support rod 42 fixed at its lower end on the outer wall of the filling barrel 1, a fixed plate 41 horizontally fixed to the upper end of the support rod 42 and fixedly connected to the outer wall of the filling barrel 1, a driving motor 43 fixedly arranged on the upper surface of the fixed plate 41 and spaced apart from the filling barrel 1, an eccentric disk 44 fixedly arranged on the output shaft of the driving motor 43, a driving connecting rod 45 having one end rotatably connected to the eccentric disk 44 and located on the upper surface of the eccentric disk 44, and a support rod 46 fixedly arranged at the lower part of the driving connecting rod 45 at its upper end, and a universal wheel fixedly provided at the lower end of the support rod 46, and the universal wheel is located on the upper surface of the fixed plate 41.

[0045] Combine Figure 1 and Figure 3 The impact assembly 5 includes a vertically arranged mounting plate 51, one surface of which is fixedly hinged to the end of the driving connecting rod 45 away from the eccentric disk 44; a buffer 52 fixedly arranged on the surface of the mounting plate 51 facing away from the driving rod; an impact plate 53 fixedly arranged on the buffering end of the buffer 52; and two spaced-apart baffles 54, both fixed to the outer wall of the filling barrel 1. The mounting plate 51 and the two sides of the impact plate 53 are respectively in contact with the surfaces of the two baffles 54, thereby limiting the movement of the impact plate 53. The surface of the impact plate 53 close to the outer wall of the filling barrel 1 can be in contact with the outer wall of the filling barrel 1. When the driving connecting rod 45 drives the impact plate 53, the impact plate 53 always abuts against the two baffles 54.

[0046] Reference Figure 3 Universal wheels are installed at the bottom of the impact plate 53 and the mounting plate 51 respectively, and the universal wheels are located on the fixed plate 41, thereby reducing the friction between the impact plate 53 and the mounting plate 51 and the fixed plate 41 during movement, which is conducive to the smooth operation of the impact assembly 5.

[0047] Reference Figure 3 The buffer member 52 includes a housing 521 fixed to the mounting plate 51, a limiting plate 522 movably disposed within the housing 521, a spring 523 disposed within the housing 521 and in an extended state, and a telescopic rod 524 movably disposed at both ends through the housing 521 and the mounting plate 51. One end of the telescopic rod 524 is fixedly connected to the impact plate 53, and the other end of the telescopic rod 524 is located on the side of the mounting plate 51 connected to the drive connecting rod 45. The telescopic rod 524 is disposed through the limiting plate 522 and is fixedly connected to the limiting plate 522. The housing 521 has an open end and a closed end, respectively. The open end is connected to the mounting plate 51. The limiting plate 522 is located between the closed end of the housing 521 and the spring 523, thereby enabling the telescopic rod 524 to extend and retract within the housing 521, thereby providing a buffer for the impact plate 53 when it strikes the outer wall of the filling barrel 1.
