Description

Technical Field

[0001] The utility model relates to a motor assembly, in particular to an adjustable motor assembly. Background Art

[0002] At present, in the field of mixers or agitators, motors are generally fixedly installed. For example, in a Chinese patent with the publication number "CN217862179U" and the name "A color masterbatch mixing device", the body of the driving motor is fixedly installed on the top surface of the mixer body, and the output shaft of the driving motor is coaxially connected to a stirring shaft extending into the mixing chamber. Another example is the Chinese patent with the publication number "CN221287477U" and the name "An agitator with a shaft seal closing device", where the body of the motor is fixedly installed at the rear end or one side of the frame, and its output end is fixedly connected to the stirring shaft through a coupling inside the frame.

[0003] This kind of fixedly installed motor is suitable for mixing or stirring devices with a fixed stirring shaft. In order to avoid cross - contamination between materials and improve the feeding efficiency of materials, manufacturers connect the stirring shaft to the feeding port of an independent silo through a connecting device, and realize the quick disconnection and connection between the stirring shaft and the motor drive shaft through a lifting device and a shaft docking device that can be quickly disengaged, so as to achieve efficient feeding and mixing of materials and avoid cross - contamination of materials, and facilitate the cleaning and maintenance of the stirring shaft.

[0004] Since the positions of the feeding ports of silos of different models have certain differences, and during mixing, in order to ensure the feeding efficiency, the silo feeds materials at a fixed position on the mixer rack. At the same time, in order to facilitate the quick docking of the shaft docking device, it is required that the position of the motor body has a certain degree of mobility to adjust the position of the motor output shaft relative to the stirring shaft so that it can be coaxial with the stirring shaft and quickly dock. After docking, the motor body also needs to be quickly fixed to achieve stable driving and then stir the materials. For existing driving motors, their bodies are fixed by bolts and other components. In order to achieve position adjustment, generally, a method of setting several independent mounting holes on the motor base is used. However, this adjustment method is not only cumbersome in installation and disassembly, but also the motor position can only be adjusted at several fixed positions, which cannot meet the above requirements. Summary of the Invention

[0005] To solve the above - mentioned technical problems, the utility model provides an adjustable motor assembly in which the position of the motor body can be quickly adjusted and fixed.

[0006] The utility model discloses an adjustable motor assembly, comprising a motor, which further comprises a base, wherein the base has a working cavity inside, wherein a motor mounting plate and an inflatable airbag are arranged in the working cavity, wherein the body of the motor is fixedly arranged on the motor mounting plate, and the inflatable airbag is located between the motor mounting plate and the inner wall of the working cavity, and when the position of the motor needs to be adjusted, the inflatable airbag is deflated to the outside until the motor mounting plate and the inner wall of the working cavity are loosened, and when the position of the motor body needs to be fixed, the inflatable airbag is inflated until the motor mounting plate is pressed tightly against the inner wall of the working cavity, and the surface of the base is also provided with an output hole corresponding to the output shaft of the motor.

[0007] The advantage of the adjustable motor assembly is that a motor mounting plate for mounting the motor body is provided in the base, and an inflatable airbag for fixing the motor mounting plate is also provided in the working chamber of the base. The provision of the inflatable airbag and the motor mounting plate allows the operator to easily adjust the position of the motor mounting plate in the working chamber through the motor mounting plate, thereby adjusting the position of the motor so that it can be adapted to the corresponding type of silo. At the same time, after the position is adjusted, the operator can quickly press the motor mounting plate against the inner wall of the working chamber through the inflatable airbag, thereby quickly adjusting and fixing the position of the motor. Compared with the original motor assembly that is fastened to several fixed positions by bolt connection, the adjustable motor assembly can adjust the motor body to any position within a certain range and fix it by the inflatable airbag. The motor adjustment and fixing method is relatively simple and convenient to operate.

[0008] Furthermore, in the adjustable motor assembly of the utility model, a transmission hole penetrating through the top wall of the base and having a shape adapted to the motor mounting plate is provided on the upper surface of the base.

[0009] The setting of the transmission hole facilitates the installation of the motor mounting plate by the operator. Specifically, the operator can pass the motor mounting plate through the transmission hole and extend it into the working chamber, and then rotate it at a certain angle so that it is staggered with the transmission hole at a certain angle so that the inflatable airbag can press it against the inner wall of the working chamber.

[0010] Furthermore, in the adjustable motor assembly of the utility model, the inflatable airbag is arranged below the motor mounting plate.

[0011] The inflatable airbag is arranged below the motor mounting plate so that the inflatable airbag can press it against the top wall of the working chamber. When the position of the motor body needs to be adjusted, the motor mounting plate is separated from the top wall of the working chamber, so that the operator can easily adjust the position of the motor mounting plate.

[0012] Furthermore, in the adjustable motor assembly of the utility model, the inflatable airbag includes a plurality of inflatable airbag bodies, and the plurality of inflatable airbag bodies are evenly distributed between the motor mounting plate and the working chamber.

[0013] The arrangement of several inflatable air bags not only realizes the pressing function for the motor mounting plate, but also enables the operator to reliably fine-tune the levelness of the motor mounting plate by controlling the inflation amount of each inflatable air bag.

[0014] Furthermore, for the adjustable motor assembly of the present utility model, several first limiting rods are provided on the bottom surface of the working cavity, the bottom ends of the first limiting rods are fixedly arranged on the bottom wall of the base, and the motor mounting plate is located between the top ends of the first limiting rods and the top wall of the working cavity.

[0015] The arrangement of the first limiting rods realizes the vertical limiting and supporting functions for the motor mounting plate. At the same time, after the inflatable air bag deflates, the motor mounting plate falling on the top of the first limiting rods is more convenient for manual adjustment.

[0016] Furthermore, for the adjustable motor assembly of the present utility model, several second limiting rods are arranged beside the motor mounting plate, and the top ends of the second limiting rods are fixedly arranged on the top wall of the base.

[0017] The arrangement of the second limiting rods realizes the limiting of the rotation of the motor mounting plate.

[0018] Furthermore, for the adjustable motor assembly of the present utility model, several buffer pads are arranged on the surface of the motor mounting plate.

[0019] The arrangement of the buffer pads realizes the buffering function for the motor mounting plate to protect the motor mounting plate, and at the same time reduces the noise generated by the impact between the motor mounting plate and the base.

[0020] Furthermore, for the adjustable motor assembly of the present utility model, a docking device is arranged at the end of the motor output shaft. The docking device includes a docking seat fixedly connected to the motor output shaft, and several retaining columns are arranged on the docking seat.

[0021] The arrangement of the docking device facilitates the connection and separation of the motor output shaft from the external shaft body.

[0022] Furthermore, for the adjustable motor assembly of the present utility model, a protective cylinder is provided on the base. The top end of the protective cylinder is fixedly arranged at the output hole of the base. The inner cavity of the protective cylinder is communicated with the output hole, and the bottom end of the protective cylinder has an opening.

[0023] The arrangement of the protective cylinder realizes the protection function for components such as the motor output shaft, the docking seat and the external shaft body.

[0024] Furthermore, for the adjustable motor assembly of the present utility model, an observation hole is provided on the side wall of the protective cylinder, and a proximity switch is arranged at the observation hole.

[0025] The arrangement of the proximity switch at the observation hole realizes the detection of the external shaft body.

Detailed Embodiment

[0034] The following combines the drawings and embodiments to further describe the detailed implementation of the present utility model in detail. The following embodiments are used to illustrate the present utility model, but not to limit the scope of the present utility model.

[0035] Embodiment 1: Refer to Figures 1 to 6 , the adjustable motor assembly of this embodiment includes a motor 1. The adjustable motor assembly further includes a base 2. The base has a working cavity 3 inside. A motor mounting plate 4 and an inflatable airbag (not shown in the figure) are provided in the working cavity. The body of the motor is fixedly arranged on the motor mounting plate. The inflatable airbag is located between the motor mounting plate and the inner wall of the working cavity. When it is necessary to adjust the position of the motor, the inflatable airbag deflates to the outside until the motor mounting plate and the inner wall of the working cavity are loosened. When it is necessary to fix the position of the motor body, the inflatable airbag inflates to press the motor mounting plate against the inner wall of the working cavity. An output hole 5 corresponding to the output shaft of the motor is also provided on the surface of the base.

[0036] The advantages of the adjustable motor assembly are as follows. An electric motor mounting plate for mounting the motor body is provided inside the base, and an inflatable airbag for fixing the electric motor mounting plate is also arranged in the working cavity of the base. The arrangement of the inflatable airbag and the electric motor mounting plate enables the operator to easily adjust the position of the motor mounting plate in the working cavity through the electric motor mounting plate, thereby realizing the adjustment of the motor position to adapt it to the corresponding type of silo. At the same time, after the position is adjusted, the operator can quickly press the electric motor mounting plate against the inner wall of the working cavity through the inflatable airbag, thereby realizing the quick adjustment and fixation of the motor position. Compared with the original motor assembly fixed at several fixed positions by bolt connection, this adjustable motor assembly can adjust the motor body to any position within a certain range and fix it through the inflatable airbag. The method of adjusting and fixing the motor is relatively simple and convenient to operate.

[0037] Among them, the base and the working cavity are used for installing components such as the motor and the electric motor mounting plate. The electric motor mounting plate is used for fixing the motor body, and the inflatable airbag is used to press the electric motor mounting plate against the inner wall of the working cavity or loosen it from the inner wall of the working cavity, so that the operator can adjust and fix the motor position through the electric motor mounting plate. The output hole on the surface of the base is used for connecting the motor to external components such as a stirring shaft.

[0038] The base can be integrally formed or assembled from components such as plates and profiles.

[0039] In this embodiment, the base is integrally in the shape of a flat cuboid, which includes square tubes 6 on the left and right sides. Two substrate plates 7 are arranged in parallel between the two square tubes, and the two ends of the substrate plates are respectively fixedly connected to the square tubes on both sides.

[0040] In order to improve the strength of the base, connecting plates 8 fixedly connected to the two substrate plates can be respectively arranged on the front and back sides of the substrate plates.

[0041] In order to facilitate the connection with the material rack of the mixer, connecting seats 9 are respectively arranged at the front and back ends of the above-mentioned square tubes, and fixing bolts for fixing the connecting seats to the material rack are arranged on the connecting seats.

[0042] The connecting seat is integrally in the shape of an L, and a rib plate is connected to the L-shaped connecting seat to improve the overall strength of the connecting seat.

[0043] The above-mentioned square tubes, substrate plates and connecting plates surround to form the working cavity of the base for installing components such as the electric motor mounting plate and the inflatable airbag.

[0044] The electric motor mounting plate can be a polygonal plate. In this embodiment, the electric motor mounting plate is integrally triangular, and part of the material is cut off at the three corners of the electric motor mounting plate.

[0045] In order to facilitate the installation of the motor mounting plate, the upper surface of the base plate, i.e., the base, is provided with a transmission hole 10 penetrating the top wall of the base. The transmission hole can be adapted to the shape of the motor mounting plate so that the motor mounting plate passes through the transmission hole and enters the working cavity. After entering the working cavity, the motor mounting plate can be rotated at a certain angle so as to be offset from the transmission hole so that the inflatable airbag can press it against the inner wall of the working cavity. When the motor is installed, its bottom end passes through the transmission hole and is fixed to the motor mounting plate.

[0046] The transmission hole may also be arranged on the bottom wall of the base and combined with the output hole into one hole. In this case, the motor body may be directly arranged in the working chamber.

[0047] The inflatable airbag is used to press the motor mounting plate against the inner wall of the working chamber. It can be installed above the motor mounting plate or below the motor mounting plate. When it is above the motor mounting plate, the inflatable airbag presses the motor mounting plate against the bottom wall of the base after inflation. When it is below the motor mounting plate, the inflatable airbag presses the motor mounting plate against the top wall of the base after inflation.

[0048] The inflatable airbag can be a single annular inflatable bag, or include multiple smaller inflatable bags. For example, three inflatable bags are arranged between the motor mounting plate and the bottom wall of the base. The inflatable bags are inflated or deflated through pipes and external air pumps, thereby fastening the motor mounting plate to the base.

[0049] In order to facilitate the operator to adjust the motor, preferably, the inflatable airbag is arranged between the motor mounting plate and the bottom wall of the base. In order to limit the motor mounting plate, a plurality of first limiting rods 11 are arranged on the bottom surface of the working chamber. The bottom end of the first limiting rod is fixed on the bottom wall of the base. When the inflatable airbag is deflated, the top end of the first limiting rod contacts the motor mounting plate, thereby supporting the motor mounting plate and the motor body. At this time, there is a small gap between the motor mounting plate and the top wall of the base, and the operator can manually adjust the position of the motor mounting plate. When the inflatable airbag is inflated and the motor mounting plate is pressed against the top surface of the working chamber, the first limiting rod is separated from the motor mounting plate and spaced a certain distance apart.

[0050] In addition, in order to limit the rotation angle of the motor mounting plate, a second limit rod 12 can be set on the side of the motor mounting plate, and the top end of the second limit rod can be fixed on the top wall of the base. There are at least two second limit rods, and the two second limit rods can be respectively set on the left and right sides of the motor mounting plate to limit the rotation of the motor mounting plate.

[0051] In order to buffer the impact and the noise generated during impact between the motor mounting plate and the base, a plurality of buffer pads 13 can be provided on the surface of the motor mounting plate. In this embodiment, buffer pads matching the shape of the motor mounting plate are respectively provided at three corners of the motor mounting plate, so as to effectively buffer the motor mounting plate and reduce the noise generated during motor fixation.

[0052] In order to facilitate the connection between the motor output shaft and an external shaft body, such as a stirring shaft, a docking device can be provided at the end of the motor output shaft. The docking device includes a docking seat 14 fixedly connected to the output shaft. A plurality of retaining posts 15 are provided on the docking seat. Correspondingly, a connection head matching the docking seat can be provided at the top of the stirring shaft, and a plurality of driving blocks corresponding to the retaining posts can be provided on the connection head. During docking, the driving blocks and the retaining posts are arranged at intervals, so as to realize the quick docking of the motor output shaft and the stirring shaft.

[0053] In order to protect components such as the motor output shaft, a protective cylinder 16 is provided on the base. The top end of the protective cylinder is fixedly arranged at the output hole of the base. The inner cavity of the protective cylinder communicates with the output hole. The bottom end of the protective cylinder has an opening. An observation hole 17 is provided on the side wall of the protective cylinder. A proximity switch can be provided at the observation hole to detect whether the stirring shaft is in place.

[0054] Taking a mixer as an example, the specific installation and working process of the adjustable motor assembly are briefly described below.

[0055] First, the operator inputs the motor mounting plate into the working cavity of the base through the transmission hole, and then fixes the base on the top of the mixer rack.

[0056] During mixing, the operator loads the bin equipped with the stirring shaft to a predetermined position on the rack, and aligns the stirring shaft with the motor output shaft by manual adjustment. After alignment, the oil cylinder on the rack drives the bin to rise until the connection head at the top of the stirring shaft is docked with the docking seat at the motor output end. At this time, the air pump inflates the inflatable airbag until the inflatable airbag presses the motor mounting plate against the inner wall of the base. Thereafter, the motor can drive the stirring shaft to rotate, thereby stirring the materials. After mixing is completed, each component resets according to the reverse process described above, waiting for the next mixing.

[0057] When the bin model is changed, the operator can deflate the inflatable airbag, so that the motor mounting plate is loosened from the inner wall of the working cavity. At this time, the operator can adjust the positions of the motor mounting plate and the motor by manual adjustment. After adjustment, the motor mounting plate is pressed against the base by the inflatable airbag again.

[0058] Preferably, a transmission hole penetrating the top wall of the base and matching the shape of the motor mounting plate is provided on the upper surface of the base.

[0059] The setting of the transmission hole facilitates the operator to install the motor mounting plate. Specifically, the operator can pass the motor mounting plate through the transmission hole and extend it into the working chamber, and then rotate it by a certain angle so that it is offset from the transmission hole by a certain angle, so that the inflatable airbag can press it against the inner wall of the working chamber.

[0060] Preferably, the inflatable airbag is arranged below the motor mounting plate.

[0061] Setting the inflatable airbag below the motor mounting plate enables the inflatable airbag to press it against the top wall of the working chamber. When the position of the motor body needs to be adjusted, the motor mounting plate is separated from the top wall of the working chamber, so that the operator can conveniently adjust the position of the motor mounting plate.

[0062] Preferably, the inflatable airbag includes a plurality of inflatable airbag bodies, and the plurality of inflatable airbag bodies are evenly distributed between the motor mounting plate and the working chamber.

[0063] The setting of the plurality of inflatable airbag bodies not only realizes the pressing function on the motor mounting plate, but also enables the operator to finely adjust the levelness of the motor mounting plate by controlling the inflation amount of each inflatable airbag body.

[0064] Preferably, a plurality of first limiting rods are provided on the bottom surface of the working chamber, the bottom ends of the first limiting rods are fixedly arranged on the bottom wall of the base, and the motor mounting plate is located between the top ends of the first limiting rods and the top wall of the working chamber.

[0065] The setting of the first limiting rods realizes the vertical limiting and supporting functions of the motor mounting plate. At the same time, after the inflatable airbag deflates, the motor mounting plate falling on the top of the first limiting rods is more convenient for manual adjustment.

[0066] Preferably, a plurality of second limiting rods are arranged beside the motor mounting plate, and the top ends of the second limiting rods are fixedly arranged on the top wall of the base.

[0067] The setting of the second limiting rods realizes the limiting of the rotation of the motor mounting plate.

[0068] Preferably, a plurality of buffer pads are arranged on the surface of the motor mounting plate.

[0069] The setting of the buffer pads realizes the buffering function of the motor mounting plate to protect the motor mounting plate, and at the same time reduces the noise generated by the impact between the motor mounting plate and the base.

[0070] Preferably, a docking device is arranged at the end of the motor output shaft. The docking device includes a docking seat fixedly connected to the motor output shaft, and a plurality of retaining columns are arranged on the docking seat.

[0071] The setting of the docking device facilitates the connection and separation of the motor output shaft from the external shaft body.

[0072] Preferably, a protective cylinder is provided on the base. The top end of the protective cylinder is fixedly arranged at the output hole of the base. The inner cavity of the protective cylinder is communicated with the output hole, and the bottom end of the protective cylinder has an opening.

[0073] The arrangement of the protective cylinder realizes the protection function for components such as the motor output shaft, the docking seat and the external shaft body.

[0074] Preferably, an observation hole is provided on the side wall of the protective cylinder, and a proximity switch is arranged at the observation hole.

[0075] The arrangement of the proximity switch at the observation hole realizes the detection of the external shaft body.
