Description

Technical Field

[0001] This application relates to the field of plastic pellet mixing technology, and mainly to a mixer. Background Technology

[0002] In practical applications of mixing equipment, the rationality of the discharge structure directly affects operational efficiency and material handling quality. Currently, the discharge design of mainstream mixing mechanisms has many problems that urgently need to be solved. Most equipment places the discharge port on the side of the mixing tank. Although this can achieve basic discharge function, due to the viscosity of the material itself and the curvature and drop of the inner wall of the mixing tank, residue is easily formed at the bottom of the tank, resulting in incomplete discharge. Especially for high-viscosity materials, the residue can be as high as 5%-8%, which not only wastes materials but also requires regular manual cleaning, increasing additional operating costs. Some designs place the discharge port at the bottom center of the mixing tank to improve the thoroughness of discharge, but the bottom of the tank needs to be designed with a sloping and narrowing structure to accommodate the discharge. Although this shape is conducive to the material gathering towards the discharge port, it creates a blind spot in the corner of the bottom of the tank, where materials easily accumulate and hide, seriously affecting the uniformity of mixing. If the mixing shaft is extended to the discharge port area to eliminate the blind spot, it is easy to interfere with the discharge process, causing material discharge to be obstructed. Another type of equipment uses a tilting unloading method, achieving unloading by tilting the entire mixing tank. However, this requires a complex hydraulic tilting mechanism, making operation cumbersome, and each tilting generates impact loads on the connection between the mixing shaft and the tank. After long-term operation, components such as the mixing blades and bushings are prone to loosening or fatigue damage, significantly increasing the equipment failure rate and severely restricting the stability of continuous production. It is evident that most current mixers suffer from limited unloading capabilities, necessitating the design of a mixer that can guarantee both unloading effectiveness and efficiency. Therefore, existing technologies require further improvement and development. Summary of the Invention

[0005] As a sub-solution of the above technical solution, the mixer further includes: A baffle plate, corresponding to the unloading chute, is movably inserted into the unloading chute and is used to close or open the unloading chute.

Detailed Implementation

[0017] This application provides a mixer. To make the purpose, technical solution, and effects of this application clearer and more explicit, the following provides a more detailed description of this application. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0018] Reference Figures 1-3 This application provides a mixer, comprising: A mixing tank 100, wherein a first stirring shaft 200 is provided in the middle of the mixing tank 100; The first drive mechanism 220 is located below the mixing tank 100 and is used to drive the first stirring shaft 200 to rotate. The stirring blade 210 is connected to the first stirring shaft 200 and is used for stirring. The mixing tank 100 is a cylindrical structure with an upward opening, and a discharge chute 110 is provided on the bottom plate of the mixing tank 100. In this application, by providing a mixing tank 100, a sufficiently large cavity is provided to hold and mix the raw materials, specifically plastic granules. A first drive mechanism 220 drives the first mixing shaft 200 to rotate, ensuring mixing. Mixing blades 210 connected to the first mixing shaft 200 ensure proper mixing of the raw materials, facilitating the achievement of the desired mixing effect. A discharge chute 110 on the bottom plate of the mixer greatly facilitates material discharge.

[0019] In one specific embodiment of this application, the mixer further includes: Baffle 120 corresponds to unloading chute 110. Baffle 120 is movably inserted into unloading chute 110 and is used to close or open unloading chute 110. In this application, a discharge chute 110 is provided on the bottom plate of the mixing tank 100, and a baffle 120 is movably inserted into the discharge chute 110. During the mixing process, the baffle 120 can close the discharge chute 110, serving as part of the bottom plate to ensure the load-bearing function of the mixing tank 100. After mixing is completed, by removing the baffle 120, the discharge chute 110 is no longer closed, and the raw materials can automatically fall from the discharge chute 110 by their own weight, thereby improving the discharge efficiency.

[0020] In one specific embodiment of this application, one end of the discharge chute 110 extends through to the side of the mixing tank 100; The end of the baffle 120 away from the mixing tank 100 extends beyond the side of the mixing tank 100, and an operating groove 121 is provided on it. In this application, considering the ease of operation for operators, one end of the discharge chute 110 extends through the side of the mixing tank 100, and the baffle 120 corresponding to the discharge chute 110 can be inserted through the side of the mixing tank 100, making it convenient to open or close the discharge chute 110. The baffle 120 extends beyond the side of the mixing tank 100, and an operation groove 121 is provided at the end of the extension of the mixing tank 100, so that the operator can operate the baffle 120 through the operation groove 121.

[0021] In one specific embodiment of this application, a baffle seat 130 is provided on the lower surface of the base plate for abutting against the baffle 120; A discharge ramp 140 is provided below the discharge chute 110, and the two sides and the upwardly inclined end of the discharge ramp 140 are connected to the bottom plate. The baffle seat 130 can be provided with a corresponding mating part that abuts against the end of the baffle 120 near the mixing tank 100, which can play a positioning role for the baffle 120. The baffle seat 130 can also abut against the lower surface of the baffle 120 to ensure the load-bearing function of the baffle 120 when the unloading trough 110 is closed. In this application, the baffle seat 130 helps ensure the smooth operation of the baffle 120 in closing or opening the unloading chute 110. The unloading ramp 140 guides the material falling from the unloading chute 110 into the placement box. By connecting the upward-sloping end and both sides of the unloading ramp 140 to the bottom plate, a unloading channel is formed, which facilitates unloading and helps prevent spillage of raw materials during unloading.

[0022] In one specific embodiment of this application, the mixer further includes: A stirring blade seat 230 is sleeved on the first stirring shaft 200, and a stirring blade groove 231 is provided on the stirring blade seat 230 for detachable connection with the stirring blade 210. The blade surface of the stirring blade 210 is inclined at an angle to the bottom plate of the mixing box 100, and the direction of inclination corresponds to the stirring direction. The stirring blade 210 is close to the inner side and bottom plate of the mixing tank 100. The tilt direction of the stirring blade 210 corresponds to the stirring direction. When stirring and rotating, the angle between the side of the stirring blade 210 facing the raw material and the bottom plate of the mixing box 100 is an obtuse angle. Multiple stirring blades 210 can be set around the bottom plate of the mixing tank 100, usually four. In this application, a stirring blade seat 230 is fitted onto the first stirring shaft 200, and a stirring blade groove 231 is provided on the stirring blade seat 230. The stirring blade 210 can be installed on the stirring blade seat 230 through the stirring blade groove 231, which facilitates a detachable connection between the stirring blade 210 and the stirring blade seat 230. By setting the blade surface of the stirring blade 210 to be inclined, and the inclination angle corresponding to the stirring direction, the material located at the bottom of the mixing box 100 can be turned up by the inclined blade surface during stirring, which helps to ensure the stirring effect of the material. Specifically, after the material is turned up by stirring, it will fall back to the bottom of the mixing box 100 by its own weight. The stirring blade 210 of this application is set at the bottom of the mixing box 100. By setting the stirring blade 210 close to the inner side of the mixing box 100, it is beneficial to ensure that most of the material is stirred up and turned up, thus ensuring the stirring effect. By setting the stirring blade 210 close to the bottom plate of the mixing tank 100, most of the raw materials that the stirring blade 210 can contact can be swept to the discharge port by slowly rotating the stirring blade 210 during unloading, which helps to ensure complete unloading.

[0023] In one specific embodiment of this application, the mixer further includes: Guide plate 300 is disposed inside the mixing tank 100 and above the mixing blade 210; The guide plate 300 is inclined at an angle to the bottom plate of the mixing tank 100, and the inclination direction corresponds to the inclination direction of the mixing blade 210. The tilt direction of the guide plate 300 corresponds to the stirring direction, and the tilt direction of the guide plate 300 and the blade surface of the stirring blade 210 are the same. The guide plate 300 can be positioned so that its bottom is close to the top of the stirring blade 210, which helps to ensure the effect. In this application, by setting a guide plate 300, after the raw materials are loaded into the mixing tank 100, the stirring blades 210 located at the bottom of the mixing tank 100 continuously rotate around the bottom plate of the mixing tank 100, which can drive the raw materials to rotate as a whole. During this process, the raw materials that maintain the trend of movement will collide with the guide plate 300. At the same time, during the continuous rotation of the stirring blades 210, the raw materials will also form a certain accumulation on the blade surface facing the raw materials, which is higher than other positions. Correspondingly, a certain area with less raw materials will be formed on the blade surface facing away from the raw materials (that is, the opposite side of the blade surface facing the raw materials on the stirring blades 210). By tilting the guide plate 300, the part of the raw materials accumulated at the stirring blades 210 can be pressed into the bottom area of ​​the mixing tank 100, avoiding the raw materials from being overturned too much during the mixing process and spilling out of the opening of the mixing tank 100. Meanwhile, since the raw materials will also accumulate towards the inside of the mixing tank 100 under centrifugal force, the guide plate 300 is set on the inside of the mixing tank 100 to effectively cope with the centrifugal tendency of the raw materials, which is conducive to ensuring the pressing effect of the raw materials.

[0024] In one specific embodiment of this application, the mixing tank 100 further includes: The second stirring shaft 400 is disposed inside the mixing tank 100 and is located above the stirring blade 210; Mixing rod 410 is mounted on second stirring shaft 400; The second drive mechanism 420 is used to drive the second stirring shaft 400 to rotate. In this application, the stirring blade 210 mainly acts on the raw material located at the bottom of the mixing tank 100. The stirring effect on the raw material near the top of the mixing tank 100 is relatively low. By setting a second stirring shaft 400 above the stirring blade 210 and setting a mixing rod 410 on the second stirring shaft 400, the mixing rod 410 can be driven to rotate by the second driving mechanism 420 to perform local stirring of the raw material, which is beneficial to ensure the overall stirring effect in the mixing tank 100.

[0025] In one specific embodiment of this application, the mixing rod 410 is eccentrically mounted inside the mixing tank 100; The mixer also includes: L-shaped baffle 430 is installed on the mixing tank 100, corresponding to the top and side of the mixing rod 410. In this application, the mixing rod 410 has a better local stirring effect. By setting an L-shaped baffle 430 corresponding to the side of the top of the mixing rod 410, the raw materials are prevented from spilling out of the mixing box 100 when the mixing rod 410 is used for stirring.

[0026] In a specific embodiment of the mixer of this application, the baffle 120 is inserted into the discharge chute 110 for sealing, and the baffle 120 abuts against the baffle seat 130 to ensure the load-bearing function of the baffle 120. After loading an appropriate amount of raw materials into the mixing tank 100, the power supply is connected, and the first driving mechanism 220 drives the first mixing shaft 200 to rotate, and the second driving mechanism 420 drives the second mixing shaft 400 to rotate. During the mixing process, the mixing blade seat 230 is sleeved on the first mixing shaft 200 and is detachably connected to the mixing blade 210 through the mixing blade groove 231. The mixing blade 210 connected to the first mixing shaft 200 rotates circumferentially along the bottom plate of the mixing tank 100 through the rotation of the first mixing shaft 200, and the raw materials are stirred and turned up by tilting. During the turning process, the guide plate 300 will promptly press some of the raw materials back into the bottom of the mixing tank 100 to ensure the overall mixing stability. Simultaneously, the mixing rod 410, driven by the second stirring shaft 400, rotates to locally stir the raw material closer to the top of the mixing tank 100, improving the overall mixing degree of the raw material in the mixing tank 100. The L-shaped baffle 430 prevents the raw material stirred by the mixing rod 410 from spilling out of the mixing tank 100. After mixing is completed, the second drive mechanism 420 is turned off, and the power of the first drive mechanism 220 is adjusted to make the stirring blade 210 rotate slowly. Through the operating groove 121 on the baffle 120, the baffle 120 is pulled out from the discharge chute 110 from the side away from the mixing tank 100, and the discharge chute 110 is no longer closed. The raw material in the mixing tank 100 can leak out of the discharge chute 110 by its own weight and be guided by the discharge inclined plate 140 for collection. During the discharge process, the stirring blade 210 rotates slowly and approaches the inner side and bottom of the mixing tank 100, which can sweep the raw material to the discharge chute 110 to ensure complete discharge and complete mixing.

[0027] It should be understood that the application of this application is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of this application.
