Description

Technical Field

[0001] This utility model relates to the technical field of mixing devices, and in particular to a raw material mixing device for injection molding of plastic buckets. Background Technology

[0002] The raw materials for producing plastic buckets are composed of a combination of various materials, therefore, thorough mixing of these materials is necessary during production. Chinese utility model patent CN216544076U discloses a raw material mixing device for plastic bucket injection molding production. This device includes a stirring assembly and a mixing assembly positioned above the stirring assembly. The stirring assembly includes a housing and a drive motor. Multiple feed inlets are located on the side wall of the housing, and the drive motor is installed at the bottom of the housing. In this raw material mixing device for plastic bucket injection molding production, the mixing assembly enables a transmission rod to drive a connecting plate to rotate via a driven rod. The rotating connecting plate moves the raw material in the storage cavity. Simultaneously, the driven rod drives an elastic plate to rotate, which contacts the feed hopper and agitates it, thus preventing the raw material from getting stuck.

[0003] However, the discharge ports of the multiple feed hoppers of the above-mentioned raw material mixing device for injection molding of plastic buckets are not equipped with uniform material distribution components, so it cannot be guaranteed that the discharge ratio of multiple raw materials in multiple feed hoppers remains stable, and therefore improvement is needed. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a raw material mixing device for plastic bucket injection molding production that has a uniform material distribution component, which keeps the output ratio of multiple raw materials stable, improves the mixing quality of raw materials, and has good practicality.

[0005] This utility model discloses a raw material mixing device for injection molding of plastic buckets, comprising a mixing tank, a motor, a drive shaft, and stirring blades. The mixing tank has a mixing chamber inside, with an inlet at the top communicating with the mixing chamber. The motor is mounted at the bottom of the mixing tank, and the drive shaft is vertically rotatable in the middle of the mixing chamber. The motor's output shaft is connected to the drive shaft. Stirring blades are mounted on the outer wall of the drive shaft, and a discharge port is located at the bottom of the mixing tank. The device also includes a raw material tank, multiple partitions, multiple shafts, and multiple gates. The raw material tank is mounted above the mixing tank, and has a storage chamber inside. The partitions are installed in the storage chamber, dividing it into multiple raw material compartments. Discharge ports are located at the bottom of each of the raw material compartments. The multiple shafts can respectively... The system is rotatably mounted in multiple discharge ports, with gates installed on multiple shafts, each gate closing one of the discharge ports. During operation, different raw materials are loaded into multiple raw material compartments in the storage chamber of the raw material tank. The multiple shafts drive the multiple gates to rotate, causing the gates to intermittently open and close the discharge ports. When the discharge ports are open, different raw materials are fed into the mixing chamber of the mixing tank. The motor drives the drive shaft and stirring blades to rotate, and the stirring blades mix the different raw materials. After mixing, the discharge port is opened to discharge the mixed raw materials. Compared with existing technologies, this system uses multiple shafts and multiple gates to form a uniform material distribution assembly. By adjusting the opening interval of the multiple gates, the discharge ratio of various raw materials can be kept stable, improving the mixing quality of the raw materials and offering good practicality.

[0006] Preferably, it also includes multiple bevel gears 1 and 2. The multiple bevel gears 1 are concentrically mounted on multiple shafts, and the bevel gears 2 are concentrically mounted on the upper end of the drive shaft. The bevel gears 2 mesh with the multiple bevel gears 1. When the motor drives the drive shaft to rotate, the drive shaft drives the bevel gears 2 to rotate. The bevel gears 2 mesh with the multiple bevel gears 1 to drive the multiple shafts and multiple gates to rotate. By adjusting the tooth ratio of the multiple bevel gears 1 and 2, the rotation frequency of the multiple gates can be adjusted, thereby adjusting the proportion of different raw material inputs. The structure is simple and practical.

[0007] Preferably, the assembly also includes a piston cylinder, a reciprocating screw, and a piston plate. The piston cylinder is installed in the middle of the storage chamber of the raw material tank. A compressed air chamber is provided inside the piston cylinder. Multiple air inlets are provided at the upper end of the piston cylinder, and multiple air outlets are provided on the lower part of the side wall of the piston cylinder. All air inlets and outlets communicate with the compressed air chamber, and the outlets face multiple raw material compartments in the raw material tank. The reciprocating screw is vertically rotatably installed in the middle of the compressed air chamber of the piston cylinder. The lower end of the reciprocating screw is connected to the upper end of the drive shaft. The piston plate is slidably installed in the compressed air chamber of the piston cylinder. A wear-resistant sealing ring is provided between the piston plate and the inner wall of the piston cylinder. The piston plate is connected to the reciprocating screw via a threaded drive in the middle. A one-way valve is installed on the piston plate, which can only open downwards. When the drive shaft rotates, it drives the reciprocating screw to rotate, so that the piston plate can move up and down along the reciprocating screw in the air chamber of the piston cylinder. When the piston plate moves upwards, the one-way valve on the piston plate opens, allowing air from outside the piston cylinder to enter the area below the piston plate through the air inlet of the piston cylinder and the one-way valve on the piston plate. When the piston plate descends, the one-way valve on the piston plate closes, thus forcing the air in the piston cylinder through the air outlet into multiple raw material compartments of the raw material tank, blowing air onto various raw materials to dry them.

[0008] Preferably, it also includes a heater, which is installed on the upper part of the piston cylinder and located above the piston plate; when air enters the piston cylinder, it is heated by the heater, thereby improving the drying effect on various raw materials.

[0009] Preferably, it also includes a funnel, which is inverted conical in shape and installed on the lower end face of the raw material tank; the funnel gathers the raw materials discharged from multiple outlets and guides them to the center of the mixing chamber of the mixing tank, so as to prevent the raw materials from falling into the outside of the mixing tank.

[0010] Preferably, the system also includes multiple weighing devices, with the lower ends of the weighing devices connected to the mixing tank and the upper ends of the weighing devices connected to the raw material tank; the multiple weighing devices support and weigh the raw material tank, thereby calculating the input weight of the raw materials and improving the accuracy of the raw material measurement.

[0011] Preferably, it also includes a door panel and a pusher cylinder. The door panel is slidably inserted into the discharge port of the mixing tank. One end of the pusher cylinder is connected to the door panel, and the other end of the pusher cylinder is connected to the mixing tank. When the piston rod of the pusher cylinder retracts, it inserts the door panel into the discharge port of the mixing tank and closes the discharge port. When the piston rod of the pusher cylinder extends, it pulls the door panel out of the discharge port of the mixing tank and opens the discharge port, allowing the mixed raw materials to be discharged, resulting in high discharge efficiency.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: multiple shafts and multiple gates constitute a uniform material distribution assembly. By adjusting the opening interval of multiple gates, the output ratio of multiple materials can be kept stable, improving the mixing quality of raw materials and making it highly practical.

Detailed Implementation

[0021] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0022] Example 1

[0023] like Figures 1 to 7As shown, a raw material mixing device for injection molding of plastic buckets includes a mixing tank 1, a motor 2, a drive shaft 3, and stirring blades 4. The mixing tank 1 has a mixing chamber inside, and an inlet communicating with the mixing chamber is located at the top of the mixing tank 1. The motor 2 is installed at the bottom of the mixing tank 1, and the drive shaft 3 is vertically rotatably installed in the middle of the mixing chamber of the mixing tank 1. The output shaft of the motor 2 is connected to the drive shaft 3. Stirring blades 4 are installed on the outer wall of the drive shaft 3, and a discharge port is located at the bottom of the mixing tank 1. The device also includes a raw material tank 5, multiple partitions 6, multiple shafts 7, and multiple gates 8. The raw material tank 5 is installed above the mixing tank 1, and a storage chamber is located inside the raw material tank 5. The partitions 6 are installed in the storage chamber of the raw material tank 5, dividing the storage chamber into multiple raw material compartments. Discharge ports are located at the bottom of the multiple raw material compartments. The shafts 7 are rotatably mounted in multiple discharge ports, and gates 8 are installed on each shaft 7 to close the discharge ports. The system also includes multiple bevel gears 9 and 10, with the first bevel gears 9 concentrically mounted on the shafts 7 and the second bevel gears 10 concentrically mounted on the upper end of the drive shaft 3, meshing with the first bevel gears 9. A funnel 15, which is inverted conical, is installed on the lower end of the raw material tank 5. Multiple weighing devices 16 are also included, with their lower ends connected to the mixing tank 1 and their upper ends connected to the raw material tank 5. Finally, a door plate 17 and a push cylinder 18 are included; the door plate 17 is slidably inserted into the discharge port of the mixing tank 1, and one end of the push cylinder 18 is connected to the door plate 17, while the other end is connected to the mixing tank 1.

[0024] During operation, different raw materials are loaded into multiple material compartments in the storage chamber of the raw material tank 5. Multiple weighing devices 16 support and weigh the raw material tank 5 to calculate the input weight of the raw materials and improve the accuracy of the raw material input. When the motor 2 drives the drive shaft 3 to rotate, the drive shaft 3 drives the bevel gear 10 to rotate. The bevel gear 10 meshes with multiple bevel gears 9 to drive multiple shafts 7 and multiple gates 8 to rotate, causing the multiple gates 8 to intermittently open and close multiple discharge ports. When multiple discharge ports are opened, the funnel 15 gathers the raw materials discharged from the multiple discharge ports and guides them to the center of the mixing chamber of the mixing tank 1 to prevent the raw materials from scattering into the mixing tank 1. Externally, by adjusting the gear ratio of multiple bevel gears 19 and 210, the rotation frequency of multiple gates 8 can be adjusted, thereby adjusting the proportion of different raw material inputs. Motor 2 drives drive shaft 3 and stirring blades 4 to rotate. Stirring blades 4 mix different raw materials. After mixing, when the piston rod of push cylinder 18 extends, it pulls door plate 17 out of the discharge port of mixing tank 1, opening the discharge port and allowing the mixed raw materials to be discharged. Compared with the existing technology, multiple shafts 7 and multiple gates 8 constitute a uniform material distribution assembly. By adjusting the opening interval of multiple gates 8, the discharge ratio of multiple raw materials can be kept stable, improving the mixing quality of raw materials.

[0025] Example 2

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, based on Embodiment 1, it further includes a piston cylinder 11, a reciprocating screw 12, and a piston plate 13. The piston cylinder 11 is installed in the middle of the storage chamber of the raw material tank 5. A compressed air chamber is provided inside the piston cylinder 11. Multiple air inlets are provided at the upper end of the piston cylinder 11, and multiple air outlets are provided at the lower part of the side wall of the piston cylinder 11. The multiple air inlets and multiple air outlets are all connected to the compressed air chamber. The multiple air outlets are respectively oriented towards multiple raw material compartments in the raw material tank 5. The reciprocating screw 12 is vertically rotatably mounted on the piston cylinder 11. In the middle of the compressed air chamber, the lower end of the reciprocating screw 12 is connected to the upper end of the drive shaft 3. The piston plate 13 is slidably installed in the compressed air chamber of the piston cylinder 11. A wear-resistant sealing ring is provided between the piston plate 13 and the inner wall of the piston cylinder 11. The middle part of the piston plate 13 is connected to the reciprocating screw 12 by thread. A one-way air valve is provided on the piston plate 13. The one-way air valve can only be opened downwards. It also includes a heater 14, which is installed on the upper part of the piston cylinder 11 and is located above the piston plate 13.

[0027] When the drive shaft 3 rotates, it drives the reciprocating screw 12 to rotate, so that the piston plate 13 can move up and down along the reciprocating screw 12 in the air chamber of the piston cylinder 11. When the piston plate 13 moves upward, the one-way valve of the piston plate 13 opens, so that the air outside the piston cylinder 11 enters the lower part of the piston plate 13 through the air inlet of the piston cylinder 11 and the one-way valve of the piston plate 13. When the air enters the piston cylinder 11, it is heated by the heater 14. When the piston plate 13 descends, the one-way valve of the piston plate 13 closes, so that the air in the piston cylinder 11 is forced into the multiple raw material compartments of the raw material tank 5 through the air outlet, and hot air is blown on the various raw materials to dry them.

[0028] like Figures 1 to 7As shown, this utility model discloses a raw material mixing device for injection molding of plastic buckets. During operation, different raw materials are first loaded into multiple material compartments in the storage chamber of the raw material tank 5. The motor 2 drives the drive shaft 3 and the stirring blades 4 to rotate. The drive shaft 3 drives the bevel gear 10 to rotate. The bevel gear 10 meshes with multiple bevel gears 9, driving multiple shafts 7 and multiple gates 8 to rotate. This causes the gates 8 to intermittently open and close multiple discharge ports. When multiple discharge ports are opened, different raw materials are fed into the mixing chamber of the mixing tank 1. Then, the motor 2 drives the drive shaft 3 and the stirring blades 4 to rotate, and the stirring blades 4 mix the different raw materials. Finally, the rotation of the drive shaft 3 drives the reciprocating screw 12 to rotate. This allows the piston plate 13 to reciprocate up and down in the air chamber of the piston cylinder 11 along the reciprocating screw 12. When the piston plate 13 moves upward, the one-way valve of the piston plate 13 opens, allowing air from outside the piston cylinder 11 to enter below the piston plate 13 through the air inlet of the piston cylinder 11 and the one-way valve of the piston plate 13. When the piston plate 13 descends, the one-way valve of the piston plate 13 closes, thereby forcing the air in the piston cylinder 11 through the air outlet into multiple raw material compartments of the raw material tank 5, blowing hot air onto the various raw materials to dry them. Finally, after mixing is completed, when the piston rod of the push cylinder 18 extends, it pulls the door plate 17 out of the discharge port of the mixing tank 1, opens the discharge port, and discharges the mixed raw materials.

[0029] The main functions achieved by this utility model are:

[0030] 1. It has a uniform material distribution component, which keeps the output ratio of multiple raw materials stable and improves the mixing quality of raw materials;

[0031] 2. It can blow air into multiple raw material compartments of raw material tank 5 to dry various raw materials;
