Description

Technical Field

[0001] The utility model relates to the technical field of new energy, in particular to a sprocket reducer coupling device.

[0002] The utility model also relates to a mixer. Background Art

[0003] With the development of the new energy industry, the market demand for lithium batteries is increasing day by day.

[0004] In the lithium battery industry, during the production process of lithium batteries, the required powder needs to be transported to the mixing container through the bag transportation process, the bag breaking and material discharge process, and the tube cavity feeding process. For example, the powder is placed in a mixing kettle, mixing barrel, etc., and the powder in the mixing container is processed to form a slurry. Then, the mixing kettle, mixing barrel and other mixing containers are lifted to a high place for subsequent processing.

[0005] At present, in the new energy industry, food industry and other industries, mixers are widely used to process mixing vessels such as mixing kettles and mixing barrels. The mixing device on the mixer is mainly driven by a reduction motor to drive the sprocket chain transmission mechanism to achieve the mixing action. Among them, the output shaft of the reduction motor needs to form a power connection with the active sprocket in the sprocket chain transmission mechanism to drive the active sprocket and the driven sprocket to rotate.

[0006] In the prior art, the reduction motors of small mixers are all vertically installed, that is, the output shaft is in a vertical posture, and the driving sprocket is installed at the top of the output shaft. Among them, the specific connection structure between the output shaft and the driving sprocket is to directly connect with the driving sprocket through the sprocket seat installed on the motor housing, and then press the driving sprocket through the fixed pressure plate, and finally use the fixing bolt to pass through the fixed pressure plate and extend downward to connect with the output shaft. However, due to the installation space limitation of the gearbox on the reduction motor, the driving sprocket cannot be close to the reduction motor, and there is a long vertical distance between the two. As a result, if the output shaft of the reduction motor is to form a power connection with the driving sprocket smoothly, either the length of the output shaft is made longer, so that the height of the output shaft is larger, thereby shortening the vertical distance between the driving sprocket and the output shaft, and then using a conventional length of fixing bolts for connection; or a special power connector (such as a long connecting bolt, etc.) is used for long-distance connection, so that the length of the output shaft can be kept at a conventional size. However, the larger the length of the shaft, the lower the torsional stiffness. Therefore, the output shaft of the former is prone to torsional deformation during the transmission process, resulting in damage to the output shaft, inability to transmit torque normally, and high maintenance costs. The power connecting parts of the latter are similarly prone to torsional deformation, which requires frequent replacement.

[0007] Therefore, how to shorten the length of the output shaft of the reduction motor and avoid torsional deformation of the output shaft or power connector of the reduction motor on the basis of realizing the power connection between the output shaft of the reduction motor and the driving sprocket is a technical problem faced by those skilled in the art. Utility Model Content

[0008] The purpose of the utility model is to provide a sprocket reducer coupling device, which can shorten the length of the output shaft of the reduction motor and avoid torsional deformation of the output shaft or power connector of the reduction motor on the basis of realizing the power connection between the output shaft of the reduction motor and the driving sprocket. Another purpose of the utility model is to provide a mixer.

[0009] In order to solve the above technical problems, the utility model provides a sprocket reducer coupling device, comprising a motor mounting plate arranged on the body of a mixer, a reduction motor arranged on the bottom surface of the motor mounting plate, a sprocket support seat arranged on the top surface of the motor mounting plate, a connecting gasket arranged on the top surface of the sprocket support seat, and a driving sprocket arranged on the top surface of the connecting gasket;

[0010] The sprocket support seat is connected to the output shaft of the reduction motor through a primary transmission connection;

[0011] The connecting gasket has a preset height, and the top surface of the connecting gasket is connected to the bottom surface of the driving sprocket, and the bottom surface of the connecting gasket is connected to the top surface of the sprocket support seat.

[0012] Preferably, the sprocket support seat is sleeved on the outside of the output shaft, and the top inner end surface of the sprocket support seat abuts against the top end surface of the output shaft.

[0013] Preferably, the primary transmission connecting member is arranged at the center position of the sprocket support seat, and is connected to the output shaft after passing through the sprocket support seat vertically downward.

[0014] Preferably, the primary transmission connecting member is detachably connected to the sprocket support seat and the output shaft.

[0015] Preferably, a positioning ring is convexly provided on the top surface of the sprocket support seat, and the inner edge of the connecting gasket ring is sleeved on the outer edge of the positioning ring.

[0016] Preferably, the top surface of the connecting gasket is fixed on the bottom surface of the driving sprocket, and the bottom surface of the connecting gasket is fixed on the top surface of the sprocket support seat.

[0017] Preferably, the connecting gasket is detachably connected to the driving sprocket and the sprocket support seat through a plurality of secondary transmission connecting parts; each of the secondary transmission connecting parts is distributed along the circumference of the connecting gasket, and each of them connects the driving sprocket, the connecting gasket and the sprocket support seat in sequence along the vertical direction.

[0018] Preferably, the height of the connecting washer accounts for 20% to 40% of the vertical distance between the driving sprocket and the motor mounting plate.

[0019] Preferably, the primary transmission connector and the secondary transmission connector are both fastening bolts.

[0020] The utility model also provides a mixer, comprising a body and a sprocket reducer coupling device arranged on the body, wherein the sprocket reducer coupling device is specifically the sprocket reducer coupling device described in any one of the above items.

[0021] The sprocket reducer coupling device provided by the utility model mainly includes a motor mounting plate, a reduction motor, a sprocket support seat, a connecting washer, a driving sprocket and a primary transmission connector. Among them, the motor mounting plate is arranged on the body of the mixer, and is mainly used to install the reduction motor. The reduction motor is mounted on the motor mounting plate, specifically on the bottom surface of the motor mounting plate, to form a vertical mounting structure, and the output shaft of the reduction motor passes through the motor mounting plate and extends vertically upward. The sprocket support seat is arranged on the motor mounting plate, specifically on the top surface of the motor mounting plate, and is connected to the output shaft of the reduction motor through a primary transmission connector. When the output shaft of the reduction motor rotates, the power is transmitted to the sprocket support seat through the primary transmission connector, driving the sprocket support seat to rotate. The connecting washer is arranged on the top surface of the sprocket support seat, and the driving sprocket is arranged on the top surface of the connecting washer. The connecting washer has a preset height and can occupy a certain proportion of the vertical spacing between the driving sprocket and the motor mounting plate, and the top surface of the connecting washer is connected to the bottom surface of the driving sprocket, and the bottom surface of the connecting washer is connected to the top surface of the sprocket support seat.

[0022] In this way, the sprocket reducer coupling device provided by the utility model, when the output shaft of the reduction motor rotates, the output shaft drives the sprocket support seat to rotate synchronously through the primary transmission connecting member, and the sprocket support seat then drives the driving sprocket to rotate synchronously through the connecting gasket, thereby realizing power transmission from the output shaft of the reduction motor to the driving sprocket; importantly, since the driving sprocket is not directly connected to the sprocket support seat, but is connected to the sprocket support seat through the connecting gasket, and the sprocket support seat is connected to the output shaft of the reduction motor through the primary transmission connecting member, it is equivalent to the output shaft of the reduction motor forming an indirect power connection with the driving sprocket through a two-stage power transmission chain. Therefore, there is no need to achieve a single-stage power connection between the two by lengthening the output shaft of the reduction motor or using specially made long connecting bolts. Moreover, when the height of the driving sprocket is constant, the height of the connecting gasket occupies a certain vertical distance between the driving sprocket and the motor mounting plate, so that the length dimension of the output shaft of the reduction motor can be reduced; at the same time, the primary transmission connecting piece is connected between the sprocket support seat and the output shaft. Compared with the connection between the fixed pressure plate and the output shaft in the prior art, the vertical distance between the driving sprocket and the sprocket support seat can be reduced, that is, the length equal to the height of the connecting gasket, so that the length dimension of the primary transmission connecting piece is reduced.

[0023] In summary, the sprocket reducer coupling device provided by the utility model shortens the length of the output shaft of the reduction motor on the basis of realizing the power connection between the output shaft of the reduction motor and the driving sprocket, thereby avoiding torsional deformation of the output shaft of the reduction motor or the power connecting part.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Please refer to Figure 1 , Figure 1 The present invention is a schematic diagram of the overall structure of a specific implementation method provided by the present invention.

[0033] In a specific implementation manner provided by the present utility model, the sprocket reducer coupling device mainly includes a motor mounting plate 1, a reduction motor 2, a sprocket support seat 3, a connecting washer 4, a driving sprocket 5 and a primary transmission connecting piece 6.

[0034] The motor mounting plate 1 is arranged on the body of the mixer and is mainly used for mounting the reduction motor 2 .

[0035] The reduction motor 2 is mounted on the motor mounting plate 1, specifically, on the bottom surface of the motor mounting plate 1 to form a vertical mounting structure, and the output shaft 21 of the reduction motor 2 passes through the motor mounting plate 1 and extends vertically upward.

[0036] The sprocket support seat 3 is arranged on the motor mounting plate 1, specifically located on the top surface of the motor mounting plate 1, and is connected to the output shaft 21 of the reduction motor 2 through a primary transmission connecting member 6. When the output shaft 21 of the reduction motor 2 rotates, the power is transmitted to the sprocket support seat 3 through the primary transmission connecting member 6, driving the sprocket support seat 3 to rotate.

[0037] The connecting gasket 4 is arranged on the top surface of the sprocket support seat 3, and the driving sprocket 5 is arranged on the top surface of the connecting gasket 4. The connecting gasket 4 has a preset height and can occupy a certain proportion of the vertical spacing between the driving sprocket 5 and the motor mounting plate 1. In addition, the top surface of the connecting gasket 4 is connected to the bottom surface of the driving sprocket 5, and the bottom surface of the connecting gasket 4 is connected to the top surface of the sprocket support seat 3.

[0038] In this way, the sprocket reducer coupling device provided in this embodiment, when the output shaft 21 of the reduction motor 2 rotates, the output shaft 21 drives the sprocket support seat 3 to rotate synchronously through the primary transmission connecting member 6, and the sprocket support seat 3 then drives the driving sprocket 5 to rotate synchronously through the connecting gasket 4, thereby realizing the power transmission from the output shaft 21 of the reduction motor 2 to the driving sprocket 5; importantly, since the driving sprocket 5 is not directly connected to the sprocket support seat 3, but is connected to the sprocket support seat 3 through the connecting gasket 4, and the sprocket support seat 3 is connected to the output shaft 21 of the reduction motor 2 through the primary transmission connecting member 6, it is equivalent to that the output shaft 21 of the reduction motor 2 forms an indirect power connection with the driving sprocket 5 through a two-stage power transmission chain. Therefore, there is no need to achieve a single-stage power connection between the two by lengthening the output shaft 21 of the reduction motor 2 or using a specially made long connecting bolt. Moreover, when the height (H) of the driving sprocket 5 is constant, the height (L2) of the connecting gasket 4 occupies a certain vertical spacing between the driving sprocket 5 and the motor mounting plate 1, so that the length dimension (L1) of the output shaft 21 of the reduction motor 2 can be reduced; at the same time, the primary transmission connecting member 6 is connected between the sprocket support seat 3 and the output shaft 21. Compared with the prior art in which it is connected between the fixed pressure plate and the output shaft 21, it can reduce the vertical spacing between the driving sprocket 5 and the sprocket support seat 3, that is, the length equal to the height of the connecting gasket 4, so that the length dimension of the primary transmission connecting member 6 is reduced.

[0039] In summary, the sprocket reducer coupling device provided in this embodiment shortens the length of the output shaft 21 of the reduction motor 2 on the basis of realizing the power connection between the output shaft 21 of the reduction motor 2 and the driving sprocket 5, thereby avoiding torsional deformation of the output shaft 21 of the reduction motor 2 or the power connecting part.

[0040] like Figure 2 As shown, Figure 2 for Figure 1 Schematic diagram of the local structure.

[0041] In a specific embodiment of the sprocket support seat 3, the sprocket support seat 3 is specifically in a cap-shaped or cylindrical shape, and is sleeved on the output shaft 21 of the reduction motor 2, forming an inner and outer nested structure with the output shaft 21. At the same time, in order to further reduce the axial length of the primary transmission connection 6, in this embodiment, the top inner end face of the sprocket support seat 3 is specifically abutted against the top end face of the output shaft 21, thereby minimizing the axial length dimension of the primary transmission connection 6. Of course, since the top inner end face of the sprocket support seat 3 is specifically abutted against the top end face of the output shaft 21, it is equivalent to reducing the height of the sprocket support seat 3, and also increasing the height dimension of the connecting gasket 4. Therefore, the specific axial length dimension or height dimension of the sprocket support seat 3, the connecting gasket 4 and the primary transmission connection 6 needs to be comprehensively considered and coordinated, so as to ensure that the whole does not produce torsional deformation.

[0042] Further, the primary transmission connecting member 6 is specifically arranged at the center position of the sprocket support seat 3, and passes through the sprocket support seat 3 vertically downward and then connected to the top of the output shaft 21 of the reduction motor 2. Generally, the primary transmission connecting member 6 is specifically connected to the axis center position of the output shaft 21 of the reduction motor 2. Of course, multiple primary transmission connecting members 6 can also be arranged at the same time and distributed circumferentially on the top surface of the sprocket support seat 3.

[0043] In order to facilitate the disassembly and maintenance of the sprocket support seat 3, in this embodiment, the primary transmission connecting member 6 is detachably connected to the sprocket support seat 3 and the output shaft 21. Generally, the primary transmission connecting member 6 can be made of fastening bolts, rivets and other components to form a threaded connection or an anchor connection with the sprocket support seat 3 and the output shaft 21.

[0044] In order to facilitate the positioning and installation of the connection gasket 4 on the top surface of the sprocket support seat 3, in this embodiment, a positioning ring 31 is convexly provided on the top surface of the sprocket support seat 3. Specifically, the positioning ring 31 can be convexly provided in the middle area of ​​the top surface of the sprocket support seat 3 and form a ring. When installing the connection gasket 4, it is only necessary to make the inner edge of the connection gasket 4 sleeve on the outer edge of the positioning ring 31 to achieve accurate positioning of the connection gasket 4 on the top surface of the sprocket support seat 3.

[0045] In a specific embodiment of the connecting gasket 4, the top surface of the connecting gasket 4 is specifically fixed to the bottom surface of the driving sprocket 5, and the bottom surface of the connecting gasket 4 is specifically fixed to the top surface of the sprocket support seat 3. Generally, the top surface of the connecting gasket 4 can be bonded to the bottom surface of the driving sprocket 5 by an adhesive, or fixedly connected to the bottom surface of the driving sprocket 5 by a vulcanization process, a welding process, etc. Similarly, the bottom surface of the connecting gasket 4 can also be bonded to the top surface of the sprocket support seat 3 by an adhesive, or fixedly connected to the top surface of the sprocket support seat 3 by a vulcanization process, a welding process, etc.

[0046] In another specific embodiment of the connecting gasket 4, considering that the height position of the driven sprocket on the body of the mixer may change slightly, in order to ensure that the sprocket chain transmission mechanism can operate normally, the driving sprocket 5 needs to maintain the same height as the driven sprocket. To this end, in this embodiment, the connecting gasket 4 is detachably connected to the driving sprocket 5 and the sprocket support seat 3 through multiple secondary transmission connectors 7. At the same time, each secondary transmission connector 7 is evenly or unevenly distributed along the circumference of the connecting gasket 4, and each secondary transmission connector 7 vertically penetrates the driving sprocket 5, the connecting gasket 4 and the sprocket support seat 3 in sequence, and the three are tightened and connected to each other. With such arrangement, when the height of the driven sprocket changes, resulting in a certain difference between the height of the driving sprocket 5 and the height of the driven sprocket, it is only necessary to disassemble each secondary transmission connecting member 7 so that the current connecting gasket 4 is disconnected from the driving sprocket 5 and the sprocket support seat 3, and then install a new connecting gasket 4 of the corresponding height on the sprocket support seat 3, and finally, tighten the driving sprocket 5, the connecting gasket 4 and the sprocket support seat 3 again through each secondary transmission connecting member 7.

[0047] Generally, the height (L2) of the connection washer 4 accounts for 20% to 40% of the vertical spacing (H) between the driving sprocket 5 and the motor mounting plate 1, such as 25%, 30%, 35%, etc. With such a configuration, the height of the connection washer 4, the length of the output shaft 21, the length of the primary transmission connector 6, and the length of the secondary transmission connector 7 can all be within a suitable range to avoid torsional deformation. Of course, the specific sizes of the above four are not fixed and can be adjusted according to actual needs.

[0048] Each secondary transmission connecting member 7 can specifically adopt fastening bolts, rivets and other components to form a threaded connection or an anchor connection with the driving sprocket 5, the connecting washer 4 and the sprocket support seat 3.

[0049] The present embodiment also provides a mixer, which mainly includes a body and a sprocket reducer coupling device arranged on the body, wherein, since the sprocket reducer coupling device adopts all the technical solutions of the above-mentioned sprocket reducer coupling device embodiments, the mixer provided by the present embodiment also has all the technical effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0050] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
