Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of compound die machine, especially relates to a stirring mechanism of compound die machine. BACKGROUND

[0002] Compound die machine (also known as composite die coating machine) is widely used in plastic, rubber, composite material and other industries, and is mainly used for coating one or more layers of functional materials, such as coating, adhesive or other composite components, on the surface of products to improve the physical properties, chemical properties or appearance quality of materials. In the production process of compound die machine, the stirring mechanism plays a crucial role, which is responsible for uniformly mixing different coating components (such as glue, resin, pigment, etc.) to ensure the quality and consistency of the coating. However, the existing stirring mechanism of compound die machine still has some problems that cannot effectively ensure uniform stirring of materials, thereby affecting product quality and production efficiency.

[0003] Most of the compound die machines on the market currently use traditional stirring designs, such as blade stirring, drum stirring or rotor stirring, etc. Traditional stirring mechanisms often rely on simple blades or rotating devices to mix materials.

DETAILED DESCRIPTION

[0050] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0051] In the description of the present application, it should be noted that the terms used herein are only for describing the specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For the convenience of description, the size of each part shown in the drawings is not drawn in accordance with the actual proportional relationship. The technology, method and equipment known to those skilled in the art may not be discussed in detail, but in appropriate cases, the technology, method and equipment should be regarded as part of the authorized specification. In all examples shown and discussed here, any specific value should be interpreted as only exemplary, and not as a limitation. Therefore, other examples of exemplary embodiments can have different values. It should be noted that similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0052] Example 1:

[0053] As Figure 1 and Figure 2As shown, the embodiment provides a stirring mechanism of a compound molding machine, comprising:

[0054] Support plates 1, two in total, oppositely distributed;

[0055] Fixed plates 2, arranged on opposite surfaces of the two fixed plates 2;

[0056] Mixing barrels 3, arranged between the two fixed plates 2, for storing materials;

[0057] Stirring paddles 4, located inside the mixing barrels 3;

[0058] Transmission mechanisms 5, arranged on the support plates 1, for providing power to drive the stirring paddles 4 to achieve uniform stirring of the mixture;

[0059] The transmission mechanism 5 comprises:

[0060] Guide plates 51, arranged between the upper portions of the two support plates 1;

[0061] Guide grooves 52, opened on the guide plates 51;

[0062] Sliding blocks 53, slidingly arranged in the guide grooves 52;

[0063] Connecting columns 54, arranged on the top of the sliding blocks 53;

[0064] Motors 55, arranged on one side of the guide plates 51;

[0065] Transmission plates 56, arranged on the output shafts of the motors 55;

[0066] Support rods 57, arranged on the transmission plates 56, and the support rods 57 are away from the motors 55;

[0067] Pull plates 58, arranged between the support rods 57 and the connecting columns 54, and the pull plates 58 are rotationally connected with the support rods 57 and the connecting columns 54;

[0068] Motors 59, arranged on the bottom of the sliding blocks 53, and the output shafts of the motors 59 are connected with the stirring paddles 4.

[0069] In the technical solution, when the material needs to be stirred and mixed, the user first adds an appropriate amount of material into the mixing barrel 3, and then starts the motor two 59, which drives the stirring paddle 4 to rotate in the mixing barrel 3, thereby stirring and mixing the material in the mixing barrel 3. Then start the motor one 55, which drives the transmission plate 56 to rotate, and the rotating kinetic energy is transmitted to the support rod 57 through the transmission plate 56. The support rod 57 also moves, and the movement of the support rod 57 causes the pull plate 58 to displace accordingly, thereby causing the connecting column 54 to displace horizontally. The connecting column 54 drives the sliding block 53 to slide in the guide groove 52, and the guide groove 52 on the guide plate 51 ensures that the movement trajectory of the sliding block 53 is controllable to prevent excessive swinging or derailment. The motor two 59 moves the stirring paddle 4 in the mixing barrel 3 through the pull plate 58, and the stirring paddle 4 pushes the material in the barrel to be uniformly stirred, ensuring uniform stirring of the material in the mixing barrel 3. After the material is mixed, the motor is turned off, so that the material in the mixing barrel 3 can be uniformly and fully stirred, ensuring the stability and uniformity of the stirring. At the same time, the movement trajectory of the stirring paddle 4 can be accurately controlled, thereby avoiding uneven stirring or dead angles, further improving the mixing effect, and adapting to different types of materials and stirring requirements.

[0070] Embodiment 2:

[0071] The embodiment provides a stirring mechanism of a compound molding machine, which has the following technical features in addition to the technical solutions of the above embodiments.

[0072] As shown in Figures 1-4 In this embodiment, the mixing barrel 3 is provided with a heat preservation shell 6 outside, the heat preservation shell 6 is arranged between the two fixed plates 2, the heat preservation shell 6 is provided with an installation cavity 7 inside, the installation cavity 7 is provided with an electric heating pipe 8 inside, and the electric heating pipe 8 is located outside the mixing barrel 3.

[0073] In the technical solution, the design can ensure that the material remains within a constant temperature range during stirring. Maintaining a suitable temperature helps improve the uniformity of the material and avoid uneven stirring or unstable material quality due to excessively low temperature. The provision of the heat preservation shell 6 effectively isolates the temperature fluctuations of the external environment, thereby reducing energy waste. The electric heating pipe 8 uniformly conducts heat to the inside of the mixing bucket 3 by heating the outer wall of the mixing bucket 3, ensuring that the temperature of the material during stirring is not easily reduced, avoiding stirring difficulties or material solidification due to temperature reduction, and improving overall stirring efficiency. The design of the heat preservation shell 6 helps reduce heat loss, allowing for more efficient use of electrical energy during heating, thereby reducing energy consumption. Through reasonable heat preservation measures, heat energy can be effectively transferred to the inside of the mixing bucket 3, achieving better heating effect and avoiding excessive heat loss. In many industrial applications, temperature control during stirring is crucial to the final quality of the material. The combination of the electric heating pipe 8 and the heat preservation shell 6 can ensure the stability of the temperature during mixing, avoiding material clumping, incomplete reaction, or other quality problems due to temperature fluctuations. By adding the heat preservation shell 6 and the electric heating pipe 8, the stirring mechanism is not only suitable for the stirring of ordinary materials, but also can be used for material processing with strict temperature requirements, such as chemical, pharmaceutical, and food processing industries that require heat treatment. This expands the application range of the equipment and meets the needs of more processes.

[0074] As shown in Figures 1-3 In this embodiment, the optimized electric heating pipe 8 is in a spiral shape and is arranged along the length direction of the outer wall of the mixing bucket 3.

[0075] In the technical solution, the electric heating pipe 8 is arranged in a spiral around the outer wall of the mixing bucket 3 and extends along the length direction of the mixing bucket 3. The spiral structure makes the heat conduction of the electric heating pipe 8 more uniform, covering a larger surface area of the mixing bucket 3. Compared with traditional linear or simple ring design, the spiral layout can more effectively transfer heat to the outer wall of the mixing bucket 3, while avoiding local overheating or temperature unevenness.

[0076] When the electric heating pipe 8 is powered on, electrical energy is converted into heat energy, and the surface of the electric heating pipe 8 gradually warms up. Since the electric heating pipe 8 is arranged in a spiral, heat can be evenly distributed along the outer wall of the mixing bucket 3. Heat is transferred from the heating pipe to the outer wall of the mixing bucket 3, and then to the internal material through the mixing bucket 3 wall. The spiral structure ensures the uniformity of heat transfer, avoiding local overheating and thus more effectively controlling the temperature of the material.

[0077] As shown in Figure 1As shown, in this embodiment, it is optimized that a temperature sensor 9 is provided on the outside of the insulation shell 6 for real-time monitoring and adjusting the temperature of the mixing barrel 3, and sending the detected temperature information to the controller 10. The controller 10 is electrically connected to the electric heating tube 8. The controller 10 controls the operating state and power of the electric heating tube 8 according to the detected temperature information.

[0078] In this technical solution, a temperature sensor 9 is installed outside the insulation shell 6. Its primary function is to monitor the outer wall temperature of the mixing drum 3 in real time. This sensor continuously monitors the temperature of the mixing drum 3 and transmits real-time data to the controller 10. Temperature sensor 9 typically employs a thermocouple, RTD (resistance temperature detector), or other sensor type, enabling rapid and accurate detection of temperature changes. After receiving the temperature data transmitted by the temperature sensor 9, the controller 10 analyzes and determines the temperature. If the temperature exceeds or falls below the set target temperature range, the controller 10 responds according to predetermined control logic, adjusting the operating status (on or off) and heating power of the electric heating tube 8. By adjusting the power output of the electric heating tube 8, the controller 10 precisely controls the heating intensity of the heating tube. For example, if the temperature is too low, the controller 10 increases the power output of the electric heating tube 8, activating additional heating functions. When the temperature reaches a preset upper limit, the controller 10 reduces the power output of the electric heating tube 8 or shuts it off to prevent the temperature from overheating. The controller 10 automatically adjusts the on / off status of the heating tube according to the set temperature range, ensuring that the temperature of the material in the mixing drum 3 remains within the desired range. This regulation can be continuous (e.g., through PWM modulation to adjust power output) or discrete (e.g., on-off control). The electrical connection between the electric heating tube 8 and the controller 10 allows the heating process of the heating tube to be monitored by the controller 10 at all times. Through real-time temperature feedback, the controller 10 can precisely control the operation of the heating tube based on the detected temperature information, ensuring temperature stability of the material in the mixing barrel 3 throughout the mixing process. This feedback mechanism prevents excessively high or low temperatures, thereby ensuring stable mixing and material quality.

[0079] Example 3:

[0080] This embodiment provides a stirring mechanism for a mold replicating machine, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0081] like Figure 1 、 Figure 2 and Figure 4 As shown, in this embodiment, the optimization further includes a discharging mechanism 11, which includes:

[0082] The discharge port 111 is provided at the bottom of the mixing barrel 3;

[0083] A bottom cover 112 is arranged at the bottom of the mixing barrel 3 and covers the discharge port 111.

[0084] A support 113 is arranged outside the heat preservation shell 6.

[0085] A fixed shaft 114 is arranged on the support 113.

[0086] A rotating plate 115 is rotatably arranged at the lower end of the fixed shaft 114.

[0087] A connecting sleeve 116 is arranged on the rotating plate 115 and away from the fixed shaft 114.

[0088] A pull rod 117 is arranged on the connecting sleeve 116.

[0089] A connecting plate 118 is arranged between the connecting sleeve 116 and the bottom cover 112.

[0090] A rack 119 is arranged outside the heat preservation shell 6.

[0091] A cylinder 1110 is arranged on the rack 119, and the piston rod of the cylinder 1110 is connected with the pull rod 117.

[0092] In the technical solution, the stirring mechanism continuously acts during the mixing process to uniformly mix the materials. The bottom cover 112 closes the discharge port 111 to prevent the materials from leaking or being discharged at a time other than the predetermined time during the stirring process. The movement of the pull rod 117 is controlled by the cylinder 1110 to drive the pull rod 117 to act. The movement of the pull rod 117 causes the connecting sleeve 116 and the rotating plate 115 to move, thereby pushing the bottom cover 112 to open or close. Under the action of the cylinder 1110, the pull rod 117 drives the connecting sleeve 116 and the rotating plate 115 to cause the bottom cover 112 to rotate, and the rotation of the bottom cover 112 opens or closes the discharge port 111. When the bottom cover 112 is opened, the materials in the mixing barrel 3 are smoothly discharged; when the bottom cover 112 is closed, the materials are again closed in the mixing barrel 3, which ensures that the materials do not leak during the stirring or transportation process, so that the discharge of the materials can be accurately controlled when needed, and the materials are prevented from leaking or wasting during the stirring process. The opening and closing of the bottom cover 112 can be quickly and effectively controlled by driving the pull rod 117 by the cylinder 1110, which saves the time of manual operation, improves the automation level, and reduces the possibility of human operation errors. The bottom cover 112 can seal the discharge port 111 to ensure that the materials do not leak during the mixing or transportation process, thereby improving the safety and reliability of the equipment and improving the production efficiency.

[0096] The fixing block 121 is provided on the supporting plate 1;

[0097] The mounting plate 122 is disposed on the fixing block 121;

[0098] The threaded holes 123 are formed on both sides of the mounting plate 122 .

[0099] In this technical solution, by passing bolts through threaded holes 123 and fastening them to external structures or devices, mounting plate 122 can be firmly fixed in a designated position, thereby ensuring the overall stability of the stirring mechanism, preventing loosening due to stirring or vibration, and ensuring the structural stability of the entire device. The firm connection structure can withstand the mechanical shock and vibration generated during long-term operation, thereby improving the stability and service life of the device. At the same time, it makes the installation, disassembly and maintenance of the device more convenient.
