Description

Technical Field

[0001] This utility model relates to the field of mixing technology, and in particular to a molding mixing device with a conveying mechanism. Background Technology

[0002] Compression molding is a processing technology that uses molds and pressure to shape raw materials in a mold cavity. It is commonly used in rubber and plastics, metals, powder metallurgy and other fields. By placing the raw materials into a mold of a preset shape and applying specific pressure to make them conform to the shape of the mold, a product that meets the requirements is finally formed. The raw materials are made by mixing and stirring multiple materials. During the production process, multiple materials are poured into a mixer to mix the materials. Then, the raw materials are transported to the molding mechanism for molding by a delivery pump.

[0003] During the mixing process, various materials are first poured into the mixer, and the raw materials will flow into the discharge pipe of the mixer. During the mixing process, it is difficult for the material in the discharge pipe to be mixed, and the comprehensiveness of the mixing needs to be improved. Therefore, this application provides a molding mixing device with a conveying mechanism to meet the needs. Utility Model Content

[0004] This invention provides a molding and mixing device with a conveying mechanism to solve the problem that the overall mixing and stirring performance needs to be improved.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A molding and mixing device with a conveying mechanism includes a mixer and a conveying pump, wherein the conveying pump is installed at the discharge port of the mixer, and further includes:

[0007] The sealing mechanism includes a conveying pipe 1 fixedly connected to the discharge port of the mixer, a conveying pipe 2 connected to the surface of the conveying pipe 1, an installation plate installed at the end of the conveying pipe 1 away from the discharge port of the mixer, a driving component installed on the surface of the installation plate by a bracket, the output end of the driving component movably passing through the installation plate and fixed with a rubber piston, the rubber piston being slidably connected inside the conveying pipe 1, and the conveying pipe 2 connected to the inlet of the conveying pump.

[0008] Preferably, the rubber piston includes a connecting plate, and a piston head is fixed to the end of the connecting plate away from the driving component. The piston head is slidably connected inside the delivery pipe.

[0009] Preferably, the side of the connecting plate away from the driving component is wavy, and the end shape of the piston head is adapted to the end shape of the connecting plate.

[0010] Preferably, the surface of the connecting plate is provided with a through hole, the inner wall of the through hole is fixed with a connecting part, the end of the connecting part is fixed to the end of the piston head, and the diameter of the through hole on the side closer to the piston head is smaller than the diameter on the side farther from the piston head.

[0011] Preferably, an inner skeleton is pre-embedded in the inner wall of the piston head, and the inner skeleton is fixed to the end of the connecting plate.

[0012] Preferably, the connecting plate has a connecting groove on its side, and a wrapping part is fixed to the inner wall of the connecting groove, which is fixed to the end of the piston head.

[0013] Preferably, a pull rod is fixed to the inner wall of the connecting groove, and a bent portion is fixed to the end of the pull rod. Both the pull rod and the bent portion are pre-embedded in the wrapping portion.

[0014] Preferably, the end of the connecting plate is provided with a groove, the vertical part of the groove is fixed with a protrusion, and the wrapping part is fixed on the surface of the groove and the protrusion.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] In the above scheme, by setting up conveyor pipe one, conveyor pipe two, driving component and rubber piston, before mixing, the driving component is started. The driving component drives the rubber piston to move towards the discharge port of the conveyor until the end of the rubber piston is in contact with the inner wall of the mixing tank of the mixer. Then, when the raw materials are poured into the mixer, the raw materials will not flow into conveyor pipe one and conveyor pipe two. The raw materials can be mixed inside the mixer, reducing the mixing dead corners and improving the overall mixing. After mixing is completed, the driving component drives the rubber piston away from the discharge port of the mixer. The mixed raw materials will flow into the connecting pipe two along the connecting pipe one, and then be transported to the molding machine by the conveying pump.

[0017] By setting a connecting plate and a piston head, the driving component is connected to the piston head through the connecting plate. The connecting plate increases the connection area between the piston head and the driving component, thereby improving the connection strength between the driving component and the piston head. Secondly, the end of the connecting plate is wavy, which further increases the connection area between the connecting plate and the piston head, thereby improving the connection strength between the connecting plate and the piston head.

[0018] By setting an internal skeleton, which supports the inside of the piston head, the piston head is prevented from being stretched and deformed during movement, thus improving its durability.

[0019] By setting a connecting groove and a wrapping part, the wrapping part is fixed to the inner wall of the connecting groove and the end of the piston head. The connection of the wrapping head avoids stress concentration at the connection between the connecting plate and the piston head edge during the process of pulling the piston head, which would cause the connection edge of the connecting plate and the piston head to break. This further improves the connection strength between the connecting plate and the piston head. Secondly, the connecting groove increases the contact area between the wrapping part and the connecting plate, which improves the connection strength between the wrapping part and the connecting plate and prevents the two from separating.

[0020] By incorporating tie rods and bends, which act as internal supports within the wrapping section, the tie rods and bends can counteract the tensile force when the wrapping section is stretched, thereby preventing the wrapping section from detaching from the connecting plate and improving the connection strength.

[0021] By setting through holes and connecting parts, with one end of the through hole being larger than the other, the connecting parts can be prevented from detaching from the through hole. The connecting parts are fixed to the end of the piston head, thereby further improving the connection strength between the piston head and the connecting plate and improving service durability.

[0028] The following is a detailed description of a molding and mixing device with a conveying mechanism provided by this utility model, in conjunction with the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; for some known technologies, those skilled in the art can also use other alternative methods to implement the invention; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0029] like Figures 1-5 As shown, an embodiment of this utility model provides a molding and mixing device with a conveying mechanism, including a mixer 1 and a conveying pump 2. The conveying pump 2 is installed at the discharge port of the mixer 1, and also includes:

[0030] The sealing mechanism 3 includes a conveying pipe 4 fixedly connected to the outlet of the mixer 1. A second conveying pipe 5 is connected to the surface of the first conveying pipe 4. An mounting plate 6 is installed at the end of the first conveying pipe 4 furthest from the outlet of the mixer 1. A driving component 7 is mounted on the surface of the mounting plate 6 via a bracket. The output end of the driving component 7 movably passes through the mounting plate 6 and is fixed with a rubber piston 8. The rubber piston 8 is slidably connected inside the first conveying pipe 4. The second conveying pipe 5 is connected to the inlet of the conveying pump 2. The mixer 1 mixes the raw materials, and the conveying pump 2 transports the mixed raw materials to the molding press. The first conveying pipe 4 connects the outlet of the mixer 1 to the conveying pump 2. Pipe 2 5 provides a channel for the flow of raw materials. Pipe 2 5 connects pipe 1 4 and pump 2, guiding the raw materials into pump 2. Mounting plate 6 provides a mounting base for drive component 7, ensuring that the position of drive component 7 is fixed. Drive component 7 provides power to drive rubber piston 8 to slide inside pipe 1 4. Drive component 7 is an electric push rod. During mixing, rubber piston 8 blocks the outlet of mixer 1 to prevent raw materials from flowing into pipe 1 4 and pipe 2 5, reducing dead zones and improving the overall mixing. After mixing is completed, rubber piston 8 retracts, and the raw materials enter pump 2 through pipe 1 4 and pipe 2 5, achieving efficient material transportation.

[0031] like Figure 4 As shown in this embodiment, the rubber piston 8 includes a connecting plate 10. A piston head 11 is fixed at one end of the connecting plate 10 away from the driving member 7. The piston head 11 is slidably connected in the delivery pipe 4. The connecting plate 10 realizes the connection between the driving member 7 and the piston head 11, increases the connection area between the driving member 7 and the piston head 11, and improves the connection strength.

[0032] like Figure 4As shown in this embodiment, the side of the connecting plate 10 away from the driving member 7 is wavy, and the end shape of the piston head 11 is adapted to the end shape of the connecting plate 10. The wavy end of the connecting plate 10 increases the contact area with the piston head 11, improves the connection strength between the two, prevents the piston head 11 from separating from the connecting plate 10, and ensures that the two fit tightly.

[0033] like Figures 3-5 As shown in this embodiment, a through hole 15 is provided on the surface of the connecting plate 10. A connecting part 16 is fixed to the inner wall of the through hole 15. The end of the connecting part 16 is fixed to the end of the piston head 11. The diameter of the through hole 15 near the piston head 11 is smaller than the diameter of the side away from the piston head 11. The through hole 15 provides installation space for the connecting part 16. The connecting part 16 connects the connecting plate 10 and the piston head 11, forming a secondary fixation, which improves the connection reliability. The diameter of the through hole 15 near the piston head 11 is small and the diameter of the side away from the piston head 11 is large, which prevents the connecting part 16 from detaching from the through hole 15, further enhancing the connection strength between the connecting plate 10 and the piston head 11, and extending the service life of the rubber piston 8.

[0034] like Figure 4 As shown in this embodiment, an inner skeleton 9 is pre-embedded in the inner wall of the piston head 11. The inner skeleton 9 is fixed to the end of the connecting plate 10. The inner skeleton 9 supports the internal structure of the piston head 11, enhances the rigidity of the piston head 11, prevents the piston head 11 from being stretched and deformed due to force during sliding and sealing, ensures the fit between the piston head 11 and the inner wall of the delivery pipe 4, and ensures the sealing effect.

[0035] like Figure 4 and Figure 5 As shown in this embodiment, a connecting groove 12 is provided on the side of the connecting plate 10, and a wrapping part 19 is fixed on the inner wall of the connecting groove 12. The wrapping part 19 is fixed to the end of the piston head 11. The connecting groove 12 increases the contact area between the wrapping part 19 and the connecting plate 10, and improves the connection strength between the two. The wrapping part 19 wraps the connecting edge of the connecting plate 10 and the piston head 11, disperses the stress at the connection, and prevents the edge from breaking due to stress concentration.

[0036] like Figure 4 and Figure 5 As shown, in this embodiment, a pull rod 13 is fixed to the inner wall of the connecting groove 12, and a bent portion 14 is fixed to the end of the pull rod 13. Both the pull rod 13 and the bent portion 14 are embedded in the wrapping portion 19. The pull rod 13 and the bent portion 14 serve as the inner support structure of the wrapping portion 19, enhancing the tensile strength of the wrapping portion 19. When the wrapping portion 19 is pulled, the pull rod 13 and the bent portion 14 bear the tension, preventing the wrapping portion 19 from detaching from the connecting plate 10.

[0037] like Figure 4 and Figure 5As shown in this embodiment, the end of the connecting plate 10 is provided with a groove 17, the vertical part of the groove 17 is fixed with a protrusion 18, and the wrapping part 19 is fixed on the surface of the groove 17 and the protrusion 18. The groove 17 and the protrusion 18 increase the contact area and engagement degree between the connecting plate 10 and the wrapping part 19, thereby improving the connection strength between the two.

[0038] Working principle: Start the drive component 7 on the mounting plate 6. The output end of the drive component 7 drives the rubber piston 8 to move towards the discharge port of the mixer 1 until the piston head 11 is in contact with the inner wall of the mixing tank of the mixer 1.

[0039] Pour the raw materials into the mixer 1, start the mixer 1 to mix, and the rubber piston 8 blocks the conveying pipe 1 4 to prevent the raw materials from flowing into the conveying pipe 1 4 and the connected conveying pipe 2 5, thus ensuring thorough mixing.

[0040] After mixing is completed, the drive component 7 drives the rubber piston 8 away from the discharge port of the mixer 1, and the raw material flows into the first conveying pipe 4 and then into the second conveying pipe 5. The conveying pump 2 starts and conveys the raw material to the molding machine.

[0041] After feeding is completed, the drive component 7 drives the rubber piston 8 to reset and seal, waiting for the next operation.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
