Description

Technical Field

[0001] This utility model relates to the field of internal mixer technology, specifically to a dual-feed device for an internal mixer. Background Technology

[0002] In the processing and production of materials such as rubber and plastics, the internal mixer, as a key piece of equipment, undertakes the important task of mixing and refining materials. The normal operation of the internal mixer is crucial for ensuring product quality and improving production efficiency. However, most existing internal mixers use relatively simple feeding methods, mainly relying on mechanical feeding systems, which to some extent limits the flexibility and reliability of production.

[0003] Currently, many internal mixers are only equipped with mechanical feeding devices, such as the common auger feeder or pneumatic feeder. These mechanical feeding methods have advantages such as fast feeding speed and continuous feeding, which can meet the needs of large-scale production. However, in actual production, mechanical feeding devices inevitably malfunction or require regular maintenance. When the mechanical feeding system malfunctions, the entire internal mixer often has to stop operating and wait for the mechanical feeding device to be repaired before it can continue to work. This not only leads to production interruption and a significant decrease in production efficiency, but also increases production costs and affects the company's economic benefits. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dual-feed device for a mixer, which solves the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-feed device for an internal mixer, comprising:

[0006] The internal mixer feeding hopper has a feeding station reserved on the back and a manual feeding port reserved on the front. The top of the front is connected to the machine feeding receiving pipe.

[0007] The mixing chamber is located in front of the feeding chamber of the mixing machine and is connected to the machine's feeding pipe. The mixing chamber is internally connected to the mixing auger shaft.

[0008] The pressing module is installed on the upper part of the feeding hopper of the internal mixer, directly above the mixing hopper;

[0009] The sealing module is installed on the side of the pressing module.

[0010] Furthermore, the feeding station of the internal mixer feeding hopper is used for workers to stand and feed materials into the manual feeding port, and the machine feeding receiving pipe is connected to the discharge end of the external mechanical feeding equipment.

[0011] Furthermore, the dual-feed device for the internal mixer also includes:

[0012] A dust collection hood is installed on top of the feeding hopper of the internal mixer, connected to the feeding station, and its top is connected to the dust collection end of the dust removal equipment through a pipeline.

[0013] Furthermore, the pressing module includes a downward driving cylinder installed at the top of the feeding hopper of the internal mixer. The telescopic end of the downward driving cylinder extends into the interior of the feeding hopper of the internal mixer and is equipped with a counterweight block. The bottom end of the counterweight block is provided with an arc-shaped groove.

[0014] Furthermore, the sealing module includes a sealing drive cylinder installed on the side of the pressing module, and a sealing plate is installed on the telescopic end of the sealing drive cylinder.

[0015] Furthermore, a reserved opening is provided at the top of the internal mixer feeding hopper corresponding to the position of the sealing plate, and the sealing plate moves within the reserved opening when it is raised or lowered.

[0016] This invention provides a dual-feed device for an internal mixer. Compared with the prior art, it has the following advantages:

[0017] This dual-feeding device for the internal mixer employs a combination of mechanical and manual feeding. This design fundamentally solves the problem of production interruptions caused by mechanical feeding device malfunctions or maintenance in existing internal mixers. In actual production, mechanical feeding devices inevitably encounter various unforeseen situations, such as equipment failures or component damage. If relying solely on mechanical feeding, the internal mixer would have to stop operating and await repairs, which would undoubtedly severely impact production efficiency and enterprise profits. However, this device can quickly switch to manual feeding mode when mechanical feeding malfunctions. Operators can immediately feed materials into the mixing chamber through the manual feeding port, ensuring continuous operation of the internal mixer and avoiding production stoppages due to feeding problems. This significantly improves production continuity and stability, guaranteeing the normal production order of the enterprise. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a dual-feeding device for an internal mixer, mainly composed of a mixing mill feeding bin 1, a mixing bin 2, a machine feeding receiving pipe 13, a dust extraction hood 14, a mixing auger shaft 3, a pressing module 4, and a sealing module 5. The mixing mill feeding bin 1 is located at the rear of the mixing bin 2, with a feeding station 11 reserved on its back and a manual feeding port 12 on its front. The top is connected to the machine feeding receiving pipe 13 and communicates with the mixing bin 2. The dust extraction hood 14 is installed on the top of the mixing mill feeding bin 1 and communicates with the feeding station 11, and is connected to a dust removal device via a pipeline. The pressing module 4 is installed on the upper part of the mixing mill feeding bin 1 and located directly above the mixing bin 2, and the sealing module 5 is installed on the side of the pressing module 4.

[0027] The internal mixer's feeding hopper 1 serves as the initial receiving space for materials. The feeding station 11 at its rear provides workers with standing and operating space, facilitating the feeding of materials into the manual feeding port 12 at the front. The internal mixer hopper 2 is the main area for material mixing. The top of the front of the internal mixer's feeding hopper 1 is connected to the internal mixer hopper 2 via a machine feeding receiving pipe 13, allowing materials to smoothly enter the internal mixer hopper 2 from the feeding hopper 1.

[0028] The machine feeding receiving pipe 13 serves as a key channel for mechanical feeding. One end is connected to the top of the front of the internal mixer's feeding hopper 1, and the other end communicates with the interior of the internal mixer hopper 2. In practical applications, it can be connected to external mechanical feeding equipment such as auger feeders or pneumatic feeders. After the discharge end of the mechanical feeding equipment is connected to the machine feeding receiving pipe 13, materials can be mechanically transported into the internal mixer hopper 2, achieving efficient mechanical feeding.

[0029] The dust hood 14 is installed on top of the internal mixer's feeding hopper 1 and is connected to the feeding station 11. The top of the dust hood 14 is connected to the suction end of the dust removal equipment via a pipe, forming a complete dust collection system. When the dust removal equipment is working, it can generate strong suction to remove dust that is diffused into the environment by workers during the material feeding process at the feeding station 11, effectively improving the working environment and protecting the health of workers.

[0030] The mixing auger shaft 3 is rotatably connected inside the mixing chamber 2. Its rotation is driven by an external drive device, which is a known technology. The rotation of the mixing auger shaft 3 is used to tumble and mix the material, so that the material is fully mixed and reacted in the mixing chamber 2.

[0031] The pressing module 4 includes a downward driving cylinder 41 installed at the top of the internal mixer's feeding hopper 1. The telescopic end of the downward driving cylinder 41 extends into the interior of the internal mixer's feeding hopper 1 and is fitted with a counterweight block 42. An arc-shaped groove 43 is pre-formed at the bottom of the counterweight block 42. During the internal mixing process, as the internal mixer auger shaft 3 rotates to internally mix the material, the downward driving cylinder 41 pushes the counterweight block 42 downward until it presses against the upper layer of the material, thus providing auxiliary compaction. Because the internal mixer auger shaft 3 has a large mechanical rotational force, the material is easily overturned and jumps upward during internal mixing. The auxiliary compaction effect of the counterweight block 42 effectively prevents this from happening, while not affecting the rotation of the internal mixer auger shaft 3 to internally mix the material, ensuring the uniformity of the material mixing process.

[0032] The sealing module 5 includes a sealing drive cylinder 51 installed on the side of the pressing module 4, and a sealing plate 52 is installed on the telescopic end of the sealing drive cylinder 51. A pre-reserved opening is provided at the top of the internal mixer feeding hopper 1 corresponding to the position of the sealing plate 52. The sealing plate 52 moves within the pre-reserved opening during lifting and lowering. After manual feeding of materials, when sealing is required, the sealing drive cylinder 51 pushes the sealing plate 52 downwards. After the sealing plate 52 moves into position, it can block the manual feeding port 12, preventing materials from overflowing from the manual feeding port 12 during the internal mixing process, thus ensuring the smooth progress of the internal mixing process.

[0033] Workflow:

[0034] (a) Manual feeding process

[0035] Opening of the sealing plate: When manual feeding is required, the sealing plate drive cylinder 51 drives the sealing plate 52 to move upward, so that the manual feeding port 12 is opened.

[0036] Manual feeding: The staff stands at the feeding station 11 and feeds the material directly into the mixing bin 2 through the manual feeding port 12.

[0037] Sealing operation: After the material is fed in, the sealing drive cylinder 51 pushes the sealing plate 52 down to block the manual feeding port 12, preparing for the subsequent mixing process.

[0038] (II) Mechanical feeding process

[0039] Equipment connection: Connect the discharge end of an external mechanical feeding device such as an auger feeder or pneumatic feeder to the machine feeding receiving pipe 13.

[0040] Material conveying: After the mechanical feeding equipment is started, the material is conveyed to the inside of the mixing silo 2 through the machine feeding receiving pipe 13.

[0041] (III) Secret Refining Process

[0042] Assisted compaction: After the material is fed in, the downward driving cylinder 41 drives the heavy hammer block 42 to move down until it presses on the upper layer of the material, thus forming an auxiliary compaction effect on the material.

[0043] Internal mixing operation: The external drive device drives the internal mixing auger shaft 3 to rotate, turning and mixing the material. With the auxiliary compaction effect of the heavy hammer block 42, the material can be mixed more evenly, improving the mixing effect.
