Description

Technical Field

[0001] The utility model relates to a shaft-to-shaft connection device, in particular to a shaft docking device. Background Art

[0002] In the field of mixers and agitators, the agitator shaft is generally driven to rotate by a driving motor. A Chinese patent disclosed as "CN118320661A" and entitled "A high-speed mixer with adjustable angle" discloses a high-speed mixer in which the agitator motor at the bottom of the mixing box is directly fixed to the agitator shaft in the mixing box through a coupling, thereby driving the agitator shaft to rotate and achieve mixing or stirring of materials.

[0003] The agitator shaft connected by this common coupling has the following main problems. On the one hand, the installation and disassembly between the agitator shaft and the motor is cumbersome, which makes it inconvenient to clean and replace the agitator shaft. At the same time, a fixed agitator shaft can only be used on a single agitator device. In order to stir or mix materials, various materials need to be input into the agitator device separately, which not only increases the processing flow, but also has the risk of cross contamination between different materials.

[0004] To this end, it is necessary to design a stirring device in which the stirring shaft is separated from the stirring motor. During stirring, the operator installs the stirring shaft on the silo, and then quickly installs the stirring shaft on the output shaft of the stirring motor through the docking device.

[0005] In order to achieve the above purpose, the stirring shaft and the driving motor must be able to quickly engage and disengage, and for this purpose, a new shaft docking device needs to be designed to achieve this purpose. Summary of the invention

[0006] In order to solve the above technical problems, the utility model provides a shaft docking device capable of realizing rapid clutch between shafts.

[0008] The advantage of the shaft docking device is that a plurality of stop columns are arranged on the docking seat, a driving block located between the stop columns is arranged on the docking head, and after docking, a gap is provided between the driving block and the adjacent stop columns, so that the operator can realize the rapid docking and separation of the motor shaft and the stirring shaft through the docking seat and the docking head, so that the operator can quickly clutch the silo equipped with the stirring shaft and the driving motor on the rotating frame of the mixer, thereby realizing rapid loading and stirring.

[0009] Furthermore, in the shaft docking device of the utility model, a keyway for fixing the shaft is provided on the inner wall of the first shaft connecting hole.

[0016] Furthermore, in the shaft docking device of the utility model, a buffer washer located above the flange is sleeved on the outer side of the guide column, and the buffer washer is located between the flange and the sliding seat.

[0017] The provision of the buffer washer can reduce the impact between the sliding seat and the flange at the bottom end of the guide column, preventing the flange from being damaged due to excessive impact force, and at the same time it can also reduce the noise generated by the impact.

[0018] Furthermore, in the shaft docking device of the utility model, a plurality of springs are provided between the docking seat and the sliding seat, one end of the spring is connected to the docking seat, and the other end is connected to the sliding seat.

[0019] The setting of the spring enables the sliding seat and its upper stop column to quickly reset axially after separation and interlacing with the driving block, so that the bottom end of the stop column can be quickly inserted between adjacent driving blocks to achieve docking.

[0020] Furthermore, in the shaft docking device of the utility model, a spring positioning pin for installing a spring is provided on the surface of the docking seat, and the top end of the spring is sleeved on the spring positioning pin.

DETAILED DESCRIPTION

[0035] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] Example 1: See Figures 1 to 6 The shaft docking device of this embodiment includes a docking seat 1, a first shaft connecting hole 2 is provided on the surface of the docking seat, and a plurality of blocking columns 3 connected to the docking seat and capable of rotating with the docking seat are provided on the docking seat. The shaft docking device also includes a docking head 4, a second shaft connecting hole 5 is provided on the surface of the docking head, and a plurality of driving blocks 6 corresponding to the blocking columns are also provided on the docking head. After docking, each driving block is located between adjacent blocking columns and has a gap between the adjacent blocking columns.

[0037] The shaft docking device has a plurality of blocking columns on its docking seat, a driving block located between the blocking columns on its docking head, and after docking, a gap is provided between the driving block and the adjacent blocking columns, so that the operator can realize the rapid docking and separation of the motor shaft and the stirring shaft through the docking seat and the docking head, so that the operator can quickly clutch the silo equipped with the stirring shaft and the driving motor on the rotating frame of the mixer, thereby realizing rapid feeding and stirring.

[0038] During operation, the operator fixes the output end of the driving motor in the first connecting hole on the surface of the docking seat by key connection, and fixes the input end of the stirring shaft in the second shaft connecting hole of the docking head.

[0039] Next, the operator can fix the stirring shaft at the feed inlet of the silo through the sealing cover fixedly connected to the stirring shaft, and at this time, the bottom end of the stirring shaft is just located in the silo.

[0040] After the agitator shaft is installed, the operator loads the agitator shaft and the silo as a whole onto the rotating frame of the mixer, and drives it up through the lifting device on it until the docking joint at the top of the agitator shaft rises to dock with the docking seat. After docking, the drive block on the docking joint is exactly located between the corresponding adjacent stop columns. When the docking seat rotates under the drive motor, the stop column on it rotates under the drive of the docking seat. When the stop column contacts the drive block, it can push the drive block, the docking joint and the agitator shaft to rotate, thereby achieving the mixing of the material. After the mixing is completed, the silo and the agitator shaft are driven down by the lifting device, and then all components are reset to wait for the next work.

[0041] It can be seen from the above description that the shaft docking device can realize rapid clutch between shafts, thereby facilitating the installation, updating and maintenance of the shafts.

[0042] The docking seat is used to connect the first shaft, such as the output shaft of the driving motor, and its surface is provided with a first shaft connecting hole for connecting the first shaft, and the inner wall of the first shaft connecting hole can be provided with a keyway for fixing the shaft. During installation, the connecting key on the first shaft is aligned with the keyway, and its end is inserted into the first shaft connecting hole, and then fixed in the first shaft connecting hole by screws.

[0043] The stop column is used to rotate with the docking seat, and drives the docking head to rotate through the driving block, thereby driving the second shaft to rotate. The stop column can be directly fixed on the docking seat, or slidably arranged on the docking seat along the axial direction to adapt to docking with shafts of different heights.

[0044] In this embodiment, the docking seat is a cylindrical docking seat, and a guide column 7 is provided on the bottom surface of the docking seat. The cross section of the guide column is non-circular, and the top of the guide column is fixed to the surface of the docking seat. The above-mentioned first shaft connection hole extends from the top surface of the docking seat to the middle or bottom surface of the guide column. The guide column is provided with a sliding seat 8 that can move along the axial direction of the guide column. The middle part of the sliding seat has a non-circular hole adapted to the guide column, so that the sliding seat can rotate under the drive of the guide column while moving axially. Preferably, the guide column can be a rectangular guide column with a rectangular cross section, and correspondingly, the non-circular hole in the middle of the sliding seat is a rectangular hole. The blocking column is fixed on the sliding seat, and the bottom end of the guide column is provided with a flange 9 located below the sliding seat.

[0045] The arrangement of the guide post and the sliding seat enables the blocking post on the sliding seat to move along the axial direction of the guide post, thereby adjusting the height of the blocking post so that it can dock with the second shaft top docking joint at different heights. At the same time, this arrangement enables the blocking post to rise along the guide post when the driving block is lifted, thereby avoiding collision and damage between the blocking post and the driving block.

[0046] The flange at the bottom end of the guide column is used to limit the sliding seat to prevent it from falling off from the bottom end of the guide column.

[0047] When the driving block is just at the bottom of the blocking column and contacts it, the blocking column will rise a certain distance along the guide column under the lifting of the driving block. When the driving block moves to a predetermined height, the blocking column rotates a certain angle driven by the driving motor. When the blocking column passes the driving block, the blocking column and the driving block are staggered, and the blocking column can fall between the adjacent driving blocks under the action of gravity or elastic force, thereby achieving the docking of the docking seat and the docking head. After that, the blocking column continues to rotate under the drive of the driving motor and contacts the driving block, thereby pushing the driving block and the docking head to rotate.

[0048] In order to enable the blocking column to be quickly reset or docked with the docking head, a plurality of springs 10 are provided between the docking seat and the sliding seat, one end of the spring is connected to the docking seat, and the other end is connected to the sliding seat. The setting of the spring enables the blocking column on the sliding seat to be quickly axially reset after being separated and staggered from the driving block, so that the bottom end of the blocking column can be quickly inserted between adjacent driving blocks to achieve docking.

[0049] In order to achieve the installation and positioning of the spring, a spring positioning pin 11 for installing the spring can be provided on the surface of the docking seat, and the top end of the spring is sleeved on the spring positioning pin, thereby achieving the positioning and installation of the top end of the spring.

[0050] Correspondingly, a spring positioning groove 12 for positioning the spring can be provided at the bottom end of the sliding seat, and the bottom end of the spring is arranged in the spring positioning groove, thereby realizing the positioning and installation of the bottom end of the spring.

[0051] In order to reduce the impact between the sliding seat and the flange, a buffer washer 13 is provided on the outer side of the guide column and is located above the flange. The buffer washer is annular and made of an elastic material, such as a rubber material. It can reduce the impact between the sliding seat and the flange at the bottom end of the guide column, prevent the flange from being damaged due to excessive impact force, and at the same time reduce the noise generated by the impact.

[0052] The docking joint is used to connect the second shaft and dock with the docking seat, so as to realize the rotational drive of the second shaft. The middle part thereof has a second shaft connecting hole connected to the second shaft. Here, the second shaft connecting hole is a square hole, and the top end of the second shaft is a square shaft matching the square hole, so as to realize the fixation of the second shaft and the docking joint.

[0053] A plurality of drive blocks are arranged on the docking head. After docking, each drive block is located between adjacent stop columns and has a certain gap with the adjacent stop columns. Since there is a large gap between the stop columns and the drive blocks, it is more convenient for the bottom end of the stop column to extend between the drive blocks, thereby improving the efficiency of docking.

[0054] In this embodiment, the butt joint is a circular butt joint, and a sector-shaped driving block is respectively arranged on both sides of the circular butt joint. Correspondingly, two blocking columns are also arranged on the sliding seat. The two blocking columns are respectively fixed on the left and right sides of the sliding seat, and the outer side surfaces thereof are on the same cylindrical surface as the outer side surfaces of the driving blocks, and the inner side surfaces thereof are spaced a small distance from the outer peripheral surface of the circular butt joint. After butt joint, the blocking columns are exactly located between the adjacent driving blocks, and the bottom ends thereof protrude out of the bottom surface of the butt joint.

[0055] Preferably, a keyway for fixing the shaft is provided on the inner wall of the first shaft connecting hole.

[0056] The keyway on the inner wall of the first shaft connecting hole facilitates the operator to install the first shaft in the first shaft connecting hole through the connecting key.

[0057] Preferably, a guide column with a non-circular cross-section is provided on the bottom surface of the docking seat, a sliding seat is provided on the guide column, which is adapted to the guide column and can be raised and lowered along the guide column, a flange is provided at the bottom end of the guide column below the sliding seat, and the blocking column is fixed on the sliding seat.

[0058] The arrangement of the guide post and the sliding seat enables the blocking post on the sliding seat to move along the axial direction of the guide post, thereby adjusting the height of the blocking post so that it can dock with the second shaft top docking joint at different heights. At the same time, this arrangement enables the blocking post to rise along the guide post when the driving block is lifted, thereby avoiding damage between the blocking post and the driving block due to interference.

[0059] The flange at the bottom end of the guide column is used to limit the sliding seat to prevent it from falling off from the bottom end of the guide column.

[0060] Preferably, the cross section of the guide post is rectangular, and a rectangular hole matching the guide post is provided in the middle of the sliding seat.

[0061] This arrangement enables the sliding seat to move axially along the guide column and to rotate driven by the guide column.

[0062] Preferably, a buffer washer is sleeved on the outer side of the guide column and is located above the flange, and the buffer washer is located between the flange and the sliding seat.

[0063] The provision of the buffer washer can reduce the impact between the sliding seat and the flange at the bottom end of the guide column, preventing the flange from being damaged due to excessive impact force, and at the same time it can also reduce noise.

[0064] Preferably, a plurality of springs are provided between the docking seat and the sliding seat, one end of the spring is connected to the docking seat, and the other end is connected to the sliding seat.

[0065] The setting of the spring enables the sliding seat and its upper stop column to quickly reset axially after being separated and staggered from the driving block, so that the bottom end of the stop column can be quickly inserted between adjacent driving blocks to achieve docking.

[0066] Preferably, a spring positioning pin for installing a spring is provided on the surface of the docking seat, and the top end of the spring is sleeved on the spring positioning pin.

[0069] The setting of the spring positioning groove realizes the positioning and installation of the bottom end of the spring.

[0070] Preferably, the second shaft connecting hole is a square hole.
