Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a feeding mechanism of a mixer. Background Technique

[0002] During the brewing process of white liquor, it is necessary to stir the materials, which helps the mold to come into contact with starch more fully, thereby promoting the enzymatic hydrolysis effect, increasing the saccharification rate of starch, and also helps to dissipate heat, prevent the temperature from being too high during the fermentation process, and avoid generating too much acid, resulting in the death of the starter culture.

[0003] After the materials are stirred, it is necessary to transport the materials from the mixer to the transport trolley for transportation. Generally, the feeding port at the bottom of the mixer is opened, and the transport trolley is located directly below the feeding port, so that the falling materials just fall into the transport trolley. The existing feeding mechanisms of mixers are generally divided into two types. One is single-opening, that is, the feeding port has only one closed plate body, and the other is double-opening, that is, the feeding port has two closed plate bodies. There is no distinction between the two structures, and only the appropriate structure is selected according to the installation space.

[0004] For the single-opening feeding mechanism of the mixer, the closed plate body rotates around a certain axis to open the feeding port, but there is a problem, as Figure 4 shown, during the rotation of the closed plate body, it will play a guiding role in the falling of the materials, resulting in the materials falling obliquely downward relative to the feeding port of the mixer, and then the materials cannot all fall into the transport trolley directly below the feeding port. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a feeding mechanism of a mixer. When the telescopic plate assembly feeds materials, its overall length will decrease, so that during the process of gradually opening the feeding port, the interference of the telescopic plate assembly on the falling of the materials can be reduced, and the materials can be prevented from falling obliquely downward relative to the feeding port due to the guiding of the telescopic plate assembly, so as to ensure that the materials can normally fall into the transport trolley below the feeding port.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A feeding mechanism of a mixer, including a first linear driving device and a fixed rod fixed on the hopper of the mixer. A telescopic plate assembly for blocking the feeding port is rotatably arranged at the bottom of the hopper of the mixer. A sliding assembly is arranged at the bottom of the telescopic plate assembly. The driving end of the first linear driving device is rotatably connected to the sliding end of the sliding assembly, and the other end of the first linear driving device is rotatably connected to the fixed rod.

[0008] Further, the telescopic plate assembly includes a bottom plate rotatably connected to the bottom of the mixer hopper. A groove is formed on one side surface of the bottom plate. A second linear driving device is installed in the groove, and the driving end of the second linear driving device is connected to a moving plate having the same width as the bottom plate.

[0009] Further, the sliding assembly includes a slide rail fixed to the bottom of the bottom plate. A slider is slidably connected to the slide rail, and the driving end of the first linear driving device is rotatably connected to the slider.

[0010] Further, rubber pads are adhesively connected to the surfaces of the bottom plate and the moving plate that are in contact with the mixer hopper.

[0011] Further, a plurality of support blocks are arranged in the groove.

[0012] Further, both the first linear driving device and the second linear driving device are cylinders or hydraulic cylinders.

[0013] Further, a scraper in contact with the moving plate is fixed to the top of one end of the bottom plate, and the scraper is located at the top of the inlet and outlet of the groove.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] When the telescopic plate assembly of the utility model discharges materials, its overall length will decrease. Thus, during the process of the discharge port being gradually opened, the interference of the telescopic plate assembly on the falling of materials can be reduced, and the situation that materials slide obliquely downward relative to the discharge port due to the guidance of the telescopic plate assembly can be avoided, so as to ensure that the materials can normally fall into the transport trolley below the discharge port.

[0016] When the scraper of the utility model retracts into the groove of the moving plate, it can scrape the materials adhered to the top of the moving plate, thereby avoiding the materials entering the groove and causing pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0023] As Figures 1-3 shown, a blanking mechanism for a mixer includes a first linear driving device 4 and a fixed rod 3 fixed on the hopper 1 of the mixer. A telescopic plate assembly 2 for closing the blanking port is rotatably arranged at the bottom of the hopper 1 of the mixer. A sliding assembly 5 is arranged at the bottom of the telescopic plate assembly 2. The sliding assembly 5 includes a slide rail 501 fixed at the bottom of the bottom plate 201. A slide block 502 is slidably connected to the slide rail 501. The driving end of the first linear driving device 4 is rotatably connected to the slide block 502, and the other end of the first linear driving device 4 is rotatably connected to the fixed rod 3.

[0024] In this implementation mode, the telescopic plate assembly 2 includes a bottom plate 201 rotatably connected to the bottom of the hopper 1 of the mixer. A bearing and a rotating shaft are installed on the bottom plate 201. The rotating shaft is fixedly connected to a connecting block on the hopper 1 of the mixer. As Figure 1 shown, the connection position is located at the bottom of one side of the hopper 1 of the mixer. A groove body 202 is opened on one side surface of the bottom plate 201. A second linear driving device 205 is installed in the groove body 202. The driving end of the second linear driving device 205 is connected to a moving plate 204 having the same width as the bottom plate 201. Both the first linear driving device 4 and the second linear driving device 205 are cylinders or hydraulic cylinders;

[0025] When closing the blanking port of the hopper 1 of the mixer, the moving plate 204 extends. At this time, the moving plate 204 cooperates with the bottom plate 201 to block the blanking port. When blanking, the first linear driving device 4 will reset, so that the slide block 502 slides on the slide rail 501, so that the bottom plate 201 rotates. During this process, the second linear driving device 205 drives the moving plate 204 into the groove body 202. At this time, the blanking port of the hopper 1 of the mixer gradually opens. And because the overall length of the telescopic plate assembly 2 becomes smaller, therefore, the materials in the hopper 1 of the mixer will vertically fall from the opened discharge port, thus avoiding the materials from obliquely falling relative to the blanking port.

[0026] Among them, as Figure 1As shown, rubber pads 7 are adhesively connected to the surfaces of the bottom plate 201 and the moving plate 204 that come into contact with the hopper 1 of the mixer. The bottom plate 201 and the moving plate 204 are embedded in the discharge opening of the hopper 1 of the mixer. At this time, due to its own deformation ability, the rubber pad 7 can seal the gap between the bottom plate 201, the moving plate 204 and the discharge opening, improving the sealing performance.

[0027] Among them, several support blocks 203 are arranged in the groove body 202. The support blocks 203 are away from the moving plate 204 and will not affect the telescopic movement of the moving plate 204. Moreover, the support blocks 203 can improve the strength of the groove body 202.

[0028] Among them, as Figure 2 shown, a scraper 6 that comes into contact with the moving plate 204 is fixed to the top of one end of the bottom plate 201. The scraper 6 is located at the top of the inlet and outlet of the groove body 202. When the moving plate 204 retracts into the groove body 202, the scraper 6 can scrape off the materials adhering to the top surface of the moving plate 204, preventing the materials from entering the groove body 202.

[0029] Working principle: When closing the discharge opening of the hopper 1 of the mixer, the first linear driving device 4 should be used to drive the bottom plate 201 to rotate upward, so that the telescopic plate assembly 2 is in a horizontal state. Then, control the second linear driving device 205 to drive the moving plate 204 to extend out of the groove body 202 until the moving plate 204 abuts against the other side wall of the discharge opening. At this time, the telescopic plate assembly 2 will close the discharge opening. When it is necessary to convey the materials in the hopper 1 of the mixer into the transport trolley, control the first linear driving device 4 to work, and it drives the bottom plate 201 to rotate downward through the sliding assembly 5. At the same time, the second linear driving device 205 drives the moving plate 204 to retract, so that the discharge opening is gradually opened, and the interference of the telescopic plate assembly 2 on the falling of the materials is reduced, preventing the materials from obliquely discharging relative to the discharge opening due to the guidance of the telescopic plate assembly 2, and ensuring that the materials can normally fall into the transport trolley.
