Technical Field

[0001] This invention relates to the field of sand mixing equipment technology, and more particularly to a resin sand mixing equipment. Background Technology

[0002] The resin sand mixing unit is a specialized piece of equipment used in casting production. It integrates multiple functions such as material mixing, resin addition, and hardener distribution, aiming to efficiently prepare resin sand suitable for various casting process requirements. By precisely controlling the ratio of sand, resin, and hardener, and utilizing mechanical or pneumatic stirring, the unit ensures that the resin evenly coats the surface of the sand particles, forming molding sand with good fluidity and high strength. This process not only improves the molding accuracy of the molding sand and the manufacturability of complex castings, but also significantly enhances the quality of castings and production efficiency due to its controllable chemical reaction rate and excellent permeability.

[0003] In existing resin sand mixing devices, when mechanical stirring is used, raw materials tend to stick to the mixing blades, causing continuous corrosion to the blades. Existing cleaning methods do not have enough impact force to effectively clean the blades, thus reducing their lifespan. Summary of the Invention

[0004] The purpose of this invention is to provide a resin sand mixing device that can quickly and thoroughly clean the spiral agitator blades, thereby ensuring production continuity, preventing raw material residues from continuously corroding the spiral agitator blades, and thus improving the lifespan of the spiral agitator blades.

[0005] To achieve the above objectives, the present invention provides a resin sand mixing device, including a support assembly, a mixing assembly, and a cleaning assembly. The support assembly includes a base and a support frame, the support frame being fixedly connected to the base and located on one side of the base. The mixing assembly includes a support shell, a spiral stirring blade, a mounting structure, and a driving structure. The top of the support shell is provided with a slot. The support shell is detachably connected to the support frame and located on one side of the support frame. The mounting structure is located on one side of the support shell. The driving structure is located on the support shell. The spiral stirring blade is located between the mounting structure and the driving structure. The cleaning assembly includes a clamping hydraulic cylinder, a sealing plate, a first screw, a drive motor, a support block, and a cleaning nozzle. The sealing plate is slidably disposed in the slot. The output end of the clamping hydraulic cylinder is connected to the sealing plate. The support block is slidably disposed on one side of the support shell. The first screw is threadedly connected to the support block. The output end of the drive motor is fixedly connected to the first screw. The cleaning nozzle is disposed on the support block.

[0006] The spiral stirring blade includes a stirring blade body, a mounting column, and a fixing plate, with the mounting column and the fixing plate fixed on both sides of the stirring blade body.

[0007] The mounting structure includes a mounting plate, a rotating ring, and a second screw. The second screw is threadedly connected to the support shell. The rotating ring is rotatably mounted on the second screw. The mounting plate has multiple retaining teeth and is fixed to the rotating ring and connected to the fixed plate.

[0008] The mounting structure further includes a locking motor and a controller. The output end of the locking motor is connected to the second screw, and the controller is connected to the locking motor.

[0009] The spiral stirring blade also includes a sealing plate, which is fixed to one side of the mounting column.

[0010] The drive structure includes a drive motor and a connecting plate. The drive motor is fixed on the support shell. The connecting plate has a mounting groove. The mounting column is installed into the mounting groove, and the axial rotation of the mounting column is restricted by the mounting groove.

[0011] The cleaning assembly further includes a sealing strip, which is fixedly connected to the sealing plate and located between the sealing plate and the support shell.

[0012] The cleaning nozzle includes a nozzle body, a connecting pipe, and a liquid tank. The nozzle body is mounted on the support block, the connecting pipe is connected to the nozzle body, and the liquid tank is connected to the connecting pipe.

[0013] This invention discloses a resin sand mixing device. The support assembly, serving as the foundation of the entire device, consists of a robust and durable base and a meticulously designed support frame. The base provides a stable mounting platform, ensuring the stability and safety of the equipment during operation. The support frame is firmly fixed to one side of the base, not only supporting the mixing and cleaning components but also ensuring a rational layout and space utilization among the components, facilitating maintenance and operation. The mixing component is the core functional area of ​​the device, comprising key components such as a support shell, spiral agitator blades, mounting structure, and drive structure. A slot is intentionally designed on the top of the support shell, a clever design that facilitates the installation and maintenance of internal components and also provides space for the cleaning component. The support shell is detachably connected to the support frame, simplifying assembly and cleaning processes and enhancing the device's flexibility. The support shell itself is also composed of two parts bolted together, allowing for disassembly and replacement of the internal spiral agitator blades. The spiral agitator blades, through the close cooperation of the mounting and drive structures, efficiently agitate the resin sand under the action of the drive structure (such as an electric motor), ensuring uniform sand mixing. The cleaning assembly is designed to enhance the equipment's continuous operation and ease of maintenance. It primarily consists of a clamping hydraulic cylinder, a sealing plate, a first screw, a drive motor, a support block, and cleaning nozzles. The sealing plate slides flexibly within a slot on the top of the support housing and connects to the output end of the clamping hydraulic cylinder. This effectively seals the sand-mixing area during operation and allows it to open during cleaning. The support block is connected to the drive motor via the first screw and slides along the side of the support housing under motor drive. This dynamic sealing and cleaning mechanism significantly improves cleaning efficiency. The cleaning nozzles are mounted on the support block and utilize high-pressure water or specific solvents to directly clean the residual material after sand mixing, achieving rapid and thorough cleaning of the spiral agitator blades. This ensures production continuity, prevents the continued corrosion of the spiral agitator blades by residual raw materials, and extends the lifespan of the spiral agitator blades.

[0025] First Embodiment

[0026] Please see Figures 1 to 7 This invention provides a resin sand mixing device, including a support assembly 101, a mixing assembly, and a cleaning assembly 103. The support assembly 101 includes a base 104 and a support frame 105. The support frame 105 is fixedly connected to the base 104 and located on one side of the base 104. The mixing assembly includes a support shell 106, a spiral stirring blade 107, a mounting structure 108, and a driving structure 109. The top of the support shell 106 is provided with a slot. The support shell 106 is detachably connected to the support frame 105 and located on one side of the support frame 105. The mounting structure 108 is disposed on one side of the support shell 106, and the driving structure 109 is disposed on the support shell 106. The spiral stirring blade 107 is disposed between the mounting structure 108 and the driving structure 109. The cleaning assembly 103 includes a clamping hydraulic cylinder 110, a sealing plate 111, a first screw 112, a drive motor 113, a support block 114, and a cleaning nozzle 115. The sealing plate 111 is slidably disposed in the slot. The output end of the clamping hydraulic cylinder 110 is connected to the sealing plate 111. The support block 114 is slidably disposed on one side of the support shell 106. The first screw 112 is threadedly connected to the support block 114. The output end of the drive motor 113 is fixedly connected to the first screw 112. The cleaning nozzle 115 is disposed on the support block 114.

[0027] In this embodiment, the support assembly 101 serves as the basic structure of the entire device, consisting of a robust and durable base 104 and a carefully designed support frame 105. The base 104 provides a stable mounting platform, ensuring the stability and safety of the equipment during operation. The support frame 105 is firmly fixed to one side of the base 104, not only bearing the heavy responsibility of supporting the sand mixing assembly and the cleaning assembly 103 upwards, but also ensuring a reasonable layout and space utilization among the components, facilitating maintenance and operation. The sand mixing assembly is the core functional area of ​​the device, containing key components such as the support shell 106, the spiral stirring blade 107, the mounting structure 108, and the drive structure 109. The top of the support shell 106 is specially provided with a slot; this ingenious design not only facilitates the installation and maintenance of the internal components but also reserves space for the intervention of the cleaning assembly 103. The support shell 106 is detachably connected to the support frame 105, which simplifies the assembly and cleaning process and enhances the flexibility of the device. The support shell 106 itself is also composed of two parts bolted together, allowing for disassembly and replacement of the internal spiral agitator 107. The spiral agitator 107 is tightly fitted by the mounting structure 108 and the drive structure 109, efficiently agitating the resin sand under the action of the drive structure 109 (e.g., an electric motor), ensuring uniform sand mixing. The cleaning assembly 103 is designed to improve the equipment's continuous operation capability and ease of maintenance. It mainly consists of a clamping hydraulic cylinder 110, a sealing plate 111, a first screw 112, a drive motor 113, a support block 114, and a cleaning nozzle 115. The sealing plate 111 slides flexibly within a slot on the top of the support shell 106, connecting to the output end of the clamping hydraulic cylinder 110. It effectively seals the sand-mixing area during operation and can be opened during cleaning. The support block 114 is connected to the drive motor 113 via the first screw 112. Driven by the motor, it slides along the side of the support shell 106. This dynamic sealing and cleaning mechanism greatly improves cleaning efficiency. The cleaning nozzle 115 is installed on the support block 114. It uses high-pressure water or a specific solvent to directly act on the residual material after sand mixing, achieving rapid and thorough cleaning of the spiral stirring blade 107. This ensures production continuity and prevents the residual raw materials on the spiral stirring blade 107 from causing continuous corrosion, thereby extending the lifespan of the spiral stirring blade 107.

[0028] The spiral stirring blade 107 includes a stirring blade body 116, a mounting post 117, and a fixing plate 118. The mounting post 117 and the fixing plate 118 are fixed to both sides of the stirring blade body 116. The mounting post 117 and the fixing plate 118 can be installed with the mounting structure 108 and the drive structure 109 respectively, making it easier to disassemble and replace.

[0029] The mounting structure 108 includes a mounting plate 119, a rotating ring 120, and a second screw 121. The second screw 121 is threadedly connected to the support shell 106. The rotating ring 120 is rotatably mounted on the second screw 121. The mounting plate 119 has multiple retaining teeth and is fixed to the rotating ring 120, and connected to the fixed plate 118. After the mounting post 117 is connected to the drive structure 109, the mounting plate 119 can be moved closer to the fixed plate 118 by rotating the second screw 121, thereby continuously moving closer to the fixed plate 118 to complete the fixation of the spiral stirring blade 107.

[0030] The mounting structure 108 also includes a locking motor 122 and a controller 124. The output end of the locking motor 122 is connected to the second screw 121, and the controller 124 is connected to the locking motor 122. The locking motor 122 can automatically drive the second screw 121 to rotate for connection. The controller 124 can continuously monitor the torque on the locking motor 122. When the torque exceeds a preset value, it indicates that the connection is complete, and at this time, the controller can stop the locking motor 122 from operating.

[0031] The spiral stirring blade 107 also includes a sealing plate 111, which is fixed to one side of the mounting column 117. The sealing plate 111 can seal the connection between the mounting column 117 and the drive structure 109, thereby preventing raw materials from entering and facilitating subsequent replacement and installation.

[0032] The drive structure 109 includes a drive motor 113 and a connecting plate 127. The drive motor 113 is fixed to the support shell 106. The connecting plate 127 has a mounting groove into which the mounting column 117 is installed, restricting the axial rotation of the mounting column 117. The connecting plate 127 can be connected to the mounting column 117 to limit its movement, making it easier to install the spiral stirring blade 107.

[0033] The cleaning assembly 103 further includes a sealing strip 128, which is fixedly connected to the sealing plate 111 and located between the sealing plate 111 and the support shell 106. The sealing strip 128 can increase the sealing performance between the sealing plate 111 and the support shell 106, preventing raw material leakage during operation.

[0034] The cleaning nozzle 115 includes a nozzle body 129, a connecting pipe 130, and a liquid tank 131. The nozzle body 129 is mounted on the support block 114, the connecting pipe 130 is connected to the nozzle body 129, and the liquid tank 131 communicates with the connecting pipe 130. Cleaning fluid is placed in the liquid tank 131. During operation, the cleaning fluid enters the nozzle body 129 through the connecting pipe 130, facilitating continuous cleaning.

[0035] The cleaning nozzle 115 also includes a control block 132, a control rod 133, a wave guide rail 134, and a spring 135. The nozzle body 129 is rotatably mounted on the support block 114. The control block 132 has a through hole and is slidably mounted on the support block 114. The nozzle body 129 passes through the through hole. The wave guide rail 134 is fixed on the support shell 106. The control rod 133 is fixedly connected to the control block 132 and contacts the wave guide rail 134. The spring 135 is located on one side of the control block 132 and is used to abut the control rod 133 against the wave guide rail 134 through the control block 132. In order to enable the nozzle to rinse the entire spiral mixing blade 107, the nozzle body 129 of this application can swing during rinsing. Specifically, a control block 132 is sleeved on the outside of the nozzle body 129. The control block 132 is supported by the spring 135, so that the control rod 133 can abut against the variable outer surface of the wave guide rail 134. When the control rod 133 moves along the wave guide rail 134, it drives the control block 132 to move back and forth, thereby causing the nozzle body 129 to swing periodically, so as to rinse the spiral mixing blade 107 over a larger range.

[0036] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
