Description

Technical Field

[0001] The utility model relates to the field of mixers, specifically to a horizontal mixer Background Art

[0002] Mixers are generally suitable for mixing powders, granules, additives, color powders, masterbatches and plastics. After the materials enter the mixer, they are continuously stirred and turned by high-speed rotating paddles to mix them fully and evenly with other additives.

[0003] The mixer used for mixing plastic particles consists of a cylinder and an internal stirring shaft and stirring blades. The plastic particles are broken up and mixed by the high-speed stirring shaft. However, since the mixed raw materials contain not only large particles but also smaller powder raw materials, such as calcium powder, during the mixing process, these powder materials will adhere to the inner wall of the mixer with the granular raw materials, which requires staff to clean up. This cleaning method wastes manpower and also creates a burden on the staff.

[0004] In order to solve this problem, existing mixers will have a scraper installed on the stirring shaft. The far end of the scraper relative to the rotating shaft is close to the inner wall of the cylinder. When the rotating shaft drives the stirring blade to stir, it also drives the scraper to rotate. The scraper will brush off the larger particles of material attached to the inner wall. However, through observation, it is found that the cleaning effect of using a scraper alone is not good. The powdered raw materials form an attachment layer on the inner wall, which the scraper cannot completely brush off. Therefore, softer bristles are set on the end of the scraper facing the cleaning surface. However, powdered raw materials are easily enriched on the bristles. At this time, the staff needs to replace the scraper or clean the bristles in time. If they are not cleaned in time, the powder enriched on the bristles will not only clean the inner wall, but also have a certain impact on the ratio of the newly added materials. In addition, there is a certain distance between the stirring limit of the stirring blade of some mixers and the inner wall of the mixer. In the area where the stirring blade cannot reach, the mixing effect of the raw materials is very low. Based on the above problems, we proposed a horizontal mixer to solve the problem that some existing mixers have poor mixing effects, and the general cleaning device has low cleaning effect on the inside of the mixer where powdered materials need to be added, and additional manual cleaning is required.

[0033] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0034] like Figures 1 to 6As shown, the embodiment of the utility model proposes a horizontal mixer, including a body 1, a mixing drum 2 arranged on the body 1 for horizontal rotation, a support assembly 5 vertically installed on the body 1, a drive assembly 3 and a transmission assembly 4 and an air supply assembly 8 arranged on one side of the body 1, the support assembly 5 has two and is respectively rotatably connected to the two ends of the mixing drum 2, the mixing drum 2 is suspended on the body 1 under the support of the support assembly 5, the drive assembly 3 is driven by the transmission assembly 4 to connect the mixing drum 2, the mixing drum 2 is a cylindrical closed structure with a middle radius larger than the radius at both ends, and the mixing drum 2 is also rotatably provided inside Mixing assembly 7, the driving assembly 3 drives the mixing drum 2 and the stirring assembly 7 to rotate in opposite directions under the support of the support assembly 5 through the transmission assembly 4; through the above mechanism, the stirring assembly 7 inside the mixing drum 2 is also supported by the support assembly 5, and the driving assembly 3 drives the mixing drum 2 and the stirring assembly 7 to rotate in opposite directions. As the mixing drum 2 rotates, the materials therein are also turned over. At the same time, the materials in the area that the stirring assembly 7 cannot reach fall into the area that the stirring assembly 7 can stir through the turning of the mixing drum 2, and then cooperate with the stirring assembly 7 rotating in the opposite direction to the mixing drum 2 to achieve a higher stirring efficiency.

[0035] A cleaning assembly 6 is also fixedly installed inside the mixing barrel 2. The cleaning assembly 6 is fixedly installed on the supporting assembly 5 and connected to the air supply assembly 8. The cleaning assembly 6 includes a brush plate 61 arranged close to the barrel wall surface of the mixing barrel 2. A pipe 63 is provided inside the brush plate 61 and is connected to the air supply assembly 8. The brush plate 61 is also provided with a plurality of jet devices 64 connected to the pipe 63 and evenly distributed on the side surface opposite to the barrel wall. Bristles 62 are also provided around the jet device 64 in the adjacent area around the jet device 64. The top of the bristle 62 is in contact with the barrel wall surface. The jet direction of the jet device 64 covers the bristles 62 surrounding the jet device 64 and the relative inner surface of the mixing barrel 2. Through the above-mentioned mechanism, the air flow generated by the air supply component 8 is transported to the jet device 64 on the brush plate 61 through the pipe 63 connected to the air supply component 8. Bristles 62 are also arranged around the jet device 64. When the air supply component 8 supplies air, the air flow is ejected from the jet device 64 to blow away the powder raw materials contaminated on the bristles 62 and the powder raw material attachment layer attached to the inner surface of the mixing barrel 2.

[0036] Further, such as Figure 1 As shown, the stirring assembly 7 includes a rotating shaft 71 that is coaxially rotated inside the mixing drum 2 and stirring blades 72 that are fixedly connected to the side walls of the rotating shaft 71 around the rotating shaft 71. The stirring blades 72 are staggered on the rotating shaft 71, and both ends of the rotating shaft 71 extend out of the mixing drum 2. Through the above mechanism, gaps are left between the stirring blades 72 to allow the raw materials to pass through, making the rolling path of the raw materials more irregular and facilitating the mixing of the raw materials.

[0037] Furthermore, the support assembly 5 includes a barrel shaft 52 rotatably arranged at the center of the two ends of the mixing barrel 2 and sleeved with the rotating shaft 71, one end of the barrel shaft 52 extends horizontally along the axis to the outside of the mixing barrel, and the barrel shaft 52 is divided into two parts by the closed end of the mixing barrel 2. A first bearing 53 is coaxially provided at both ends to connect the rotating shaft 71, so that the rotating shaft 71 rotates inside the barrel shaft 52, so that the rotation of the stirring assembly 7 is not restricted, and a second bearing 54 is coaxially provided on the outer wall of the barrel shaft 52 to connect to the inner wall of the mixing barrel, and also includes a support plate 51, the bottom of the support plate 51 is fixedly mounted on the machine body 1, and the top is fixedly connected to the side wall of the barrel shaft 52 outside the two ends of the mixing barrel 2, and one end of the barrel shaft 52 located outside the mixing barrel 2 is fixed by the support plate 51, and the second bearing 54 that connects the barrel shaft 52 to the closed end of the mixing barrel 2 is cooperated so that the mixing barrel 2 can also rotate.

[0038] Furthermore, the drive assembly 3 includes a drive motor 31 arranged on one side of the body 1 and a reduction device 32 connected to the output end of the drive motor 31. The high speed of the drive motor 31 is reduced by the reduction device 32, such as a reduction gear set, to obtain a larger torque, and then the transmission is connected to the transmission shaft 41, and pulleys 42 are fixedly provided on the transmission shaft 41 and the rotating shaft 71 of the stirring assembly 7, and then the two pulleys 42 are connected by a belt 43 so that the rotating shaft 71 is driven by the transmission shaft 41 to rotate in the same direction, and then a gear 44 is provided at the end of the transmission shaft 41 close to the mixing drum 2 and an external gear 45 is provided around the drum body on the outer wall surface of the mixing drum 2 corresponding to the position of the gear 44. The transmission shaft 41 drives the mixing drum 2 to rotate in the opposite direction through the engagement of the external gear 45 with the gear 44.

[0039] Further, such as Figure 1 and Figure 5 As shown, the brush plate 61 includes a vertical brush plate fixedly connected to the side wall of the cylinder shaft 52 located inside the mixing cylinder 2 and a horizontal brush plate arranged close to the cylinder wall. The vertical brush plate extends radially along the end surface of the closed end of the mixing cylinder 2 to the connection between the closed end and the cylinder wall, and is connected to one end of the horizontal brush plate. The horizontal brush plate and the vertical brush plate form a whole parallel to the inner surface of the mixing cylinder 2. Figure 1 and Figure 5 The brush plate 61 shown is fixedly connected to the stationary barrel shaft 52. When the mixing barrel 2 rotates, the brush plate 61 remains stationary and brushes the inner surface of the mixing barrel 2. The entire brush plate 61 can cover the entire inner surface of the mixing barrel 2, and the bristles 62 thereon clean the raw materials attached to the inner surface of the mixing barrel 2.

[0040] Further, such as Figure 1 and Figure 5As shown, the air supply component 8 includes a compressor 81 and an air tank 82 arranged on one side of the driving component 3. The compressor 81 is used to compress high-pressure air, and the compressed air is stored in the air tank 82 connected to the compressor 81. The air tank 82 is also provided with an air pipe 83 extending to the area of ​​the cylinder shaft 52 located between the two first bearings 53. Since the cylinder shaft 52 is in a stationary state, a channel can be provided in the middle area of ​​the cylinder shaft 52 to connect the channel inside the mixing cylinder 2 with the air pipe 83. The rotating shaft 71 and the first bearing 53 and the second bearing 54 will not interfere with the channel in the middle area of ​​the cylinder shaft 52, so that the air flow can be delivered to the pipe 63 inside the brush plate 61. The air pipe 83 is also provided with a control valve 831 at one end close to the air tank 82 for separately controlling the air supply component 8 to supply air to provide high-pressure airflow when the jet device 64 blows the inner surface of the mixing cylinder 2.

[0041] Further, such as Figure 1 、 Figure 2 and Figure 3 as well as Figure 4 As shown, the jet device 64 includes a cylindrical nozzle, the height of the nozzle is lower than the height of the bristles 62, so that the airflow of the nozzle can blow the bristles 62 and the attachments on the bristles 62, and the nozzle includes a plurality of jet channels 642 that are staggered inside and connected to the channel. For example, three jet channels 642 can be set. The staggered jet channels 642 will form a bend inside the nozzle. Even if the powdered raw material enters the jet channel 642, it will stay at the bend. When the high-pressure airflow is ejected, the blockage will be cleared. The top of the jet channel 642 passes through the top of the nozzle to form a jet hole 641, one of the jet holes 641 is located at the axis of the nozzle and is used to blow the inner surface of the relative mixing barrel 2. The other two jet holes 641 are arranged on both sides around the axis and the jet direction presents a certain angle with the axis of the nozzle. The oblique airflow cooperates with the airflow ejected from the central jet hole 641 to expand the blowing range, and also allows the airflow to spray back onto the bristles 62 when it sprays onto the inner surface of the mixing barrel 2, thereby cleaning the bristles 62 itself.

[0042] Further, such as Figure 1 and Figure 6 As shown, a feed port 21 and a discharge port 22 are further provided in the middle of the mixing drum 2. Switches are also provided on the feed port 21 and the discharge port 22 to control the closed and open states of the mixing drum 2. When the mixing drum 2 needs to be cleaned, the discharge port 22 can be closed, and the suction component 9 is connected to the feed port 21. When the cleaning component 6 is jet-blown, the powdered raw material is lifted up, and the suction component 9 directly sucks the powder, thereby solving the problem of extracting the powdered raw material remaining inside the mixing drum 2 and on the cleaning component 6.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
