[0033] It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, such that the embodiments of the present invention described herein can be practiced in an order other than that illustrated or described herein.

[0034] Combine Figure 1 、 Figure 2 and Figure 4 As shown, the present invention provides a manufacturing device for a stirring shaft (hereinafter referred to as the manufacturing device), comprising a fixed-distance rotary machine 1, the fixed-distance rotary machine 1 comprising a supporting wheel set 11, the supporting wheel set 11 being used to support the ends of a square shaft 100 and a pentagonal shaft 200, so that the axes of the square shaft 100 and the axes of the pentagonal shaft 200 are parallel to each other and at the same height;

[0035] The constant speed ratio drive mechanism 2 is used to drive the square shaft 100 and the pentagonal shaft 200 to rotate synchronously at a predetermined speed ratio.

[0036] Specifically, the stirring shaft referred to in the present application is a stirring shaft of a chemical equipment, which is composed of a square shaft 100 and a pentagonal shaft 200 on which multiple groups of square disk scrapers and pentagonal disk scrapers are respectively installed. This stirring shaft has the following manufacturing and installation difficulties: the stirring shaft is composed of a square shaft 100 and a pentagonal shaft 200 on which multiple groups of square disk scrapers and pentagonal disk scrapers are respectively installed. The axis spacing between the square shaft 100 and the pentagonal shaft 200 is highly accurate (tolerance ±0.02mm), and the two rotate in a certain direction and speed ratio, and the square disk scrapers and the pentagonal disk scrapers rotate layer by layer at a certain angle. The axis spacing, the rotation direction and speed ratio must be strictly ensured during manufacturing of the stirring shaft, and the radial and axial position accuracy of the square disk scrapers and the pentagonal disk scrapers must be strictly ensured. Any slight deviation will cause interference; the two are not connected but mesh with each other, and they must be accurately installed after manufacturing. The shell has a gap of only 5mm, and its orientation and accuracy must be strictly guaranteed not to change during the installation process. The present invention uses a fixed-distance rotary machine 1 to lift the square shaft 100 and the pentagonal shaft 200, and arranges a support wheel group 11 at each end of the square shaft 100 and the pentagonal shaft 200. Each support wheel group 11 consists of two support rollers 111, and the ends of the square shaft 100 and the pentagonal shaft 200 are placed between the two support rollers 111, that is to say, at least one support wheel group 11 is provided at each end of the square shaft 100 and the pentagonal shaft 200. Of course, the support wheel group 11 is limited to the above-mentioned arrangement. It is also possible to arrange as many support wheel groups 11 as possible at the ends of the square shaft 100 and the pentagonal shaft 200 according to the length of the square shaft 100 and the pentagonal shaft 200 to improve the stability of the square shaft 100 and the pentagonal shaft 200 during rotation.

[0037] In this embodiment, there are four supporting wheel groups 11 on the fixed-distance rotary machine 1, and these four supporting wheel groups 11 are arranged at the four corners of a rectangular track, so that the four-corner shaft 100 and the pentagonal shaft 200 can be parallel to each other and at the same height after being lifted, thereby maintaining the axial and radial rotation accuracy of the four-corner shaft 100 and the pentagonal shaft 200, and avoiding the situation where the four-corner shaft 100 and the pentagonal shaft 200 have motion interference during the subsequent installation of the four-corner disk scraper and the pentagonal disk scraper.

[0038] Combine Figure 1 、 Figure 2 and Figure 4 As shown, the fixed-distance rotary machine 1 also includes a support frame 12 for installing a support wheel group 11. Each support wheel group 11 includes two support rollers 111. The support rollers 111 are rotatably connected to the support frame 12 through roller shafts 112, and the two support rollers 111 are at the same height.

[0039] Specifically, the two support rollers 111 of each group are at the same height, and a spacing is reserved between the two support rollers 111, so that the square shaft 100 and the pentagonal shaft 200 can be clamped between the two support rollers 111. The spacing between the two support rollers 111 should not be too small. If the spacing is too small, the square shaft 100 and the pentagonal shaft 200 will slide out of the support rollers 111 under the action of external force, thereby achieving the radial limiting effect and flexible rotation effect of the square shaft 100 and the pentagonal shaft 200.

[0040] In this embodiment, each group of support wheel groups 11 is not limited to two support rollers 111, and a support roller 111 can also be added between the two support rollers 111. The support roller 111 is used to support the circumference below the end of the square shaft 100 or the pentagonal shaft 200, so as to further disperse the mass of the square shaft 100 or the pentagonal shaft 200, thereby reducing the weight borne by each support roller 111, which helps to improve the service life of the support roller 111.

[0041] Specifically, the distance between the two support rollers 111 of each support wheel group 11 can be adjusted. In one embodiment, the two support rollers 111 are respectively installed on their respective small bases, and a dovetail groove guide rail, a V-shaped guide rail or a cylindrical guide rail pair is provided at the lower part of the small base and the movable cooperation with the bracket to achieve the purpose of free sliding of the small base on the bracket. Each small base is equipped with a trapezoidal thread screw in the same direction as the guide rail, and the two support rollers 111 are driven to move independently and adjusted to the required spacing by rotating the trapezoidal thread screw; in one embodiment, the support rollers 111 are respectively installed on their respective small bases, and a dovetail groove guide rail, a V-shaped guide rail or a cylindrical guide rail pair is provided at the lower part of the small base and the movable cooperation part of the bracket to achieve the purpose of free sliding of the small base on the bracket, and a ball screw is installed on the upper part of the bracket, whose center plane coincides with the center plane of the bracket, and two sliders with opposite movement directions are symmetrically installed on both sides of the center plane of the ball screw and are fixed to the small base, and by rotating the ball screw, the two support rollers 111 can be driven to slide in opposite directions or in opposite directions at the same time, and the ball screw is fixed after adjusting to the required spacing; in one embodiment The two support rollers 111 are respectively installed on their respective small bases, and a dovetail groove guide rail, a V-shaped guide rail or a cylindrical guide rail pair is provided at the lower part of the small base and the movable cooperation part of the bracket to achieve the purpose of free sliding of the small base on the bracket. Each small base is installed with an equal-length connecting rod, and an electric push rod is installed at the bottom of the bracket. The extended end of the electric push rod and the connecting rod are hinged at the center plane. Through the extension and contraction of the electric push rod, the roller group is driven to slide in the opposite direction or in the opposite direction. Therefore, the use requirements of different types of shafts can be met by controlling the spacing between the two support rollers 111 of each set of support wheel groups 11, and the two support rollers 111 can immediately maintain a stable state after adjusting the spacing, thereby achieving the purpose of accurately controlling the spacing between the four-angle shaft 100 and the five-angle shaft 200.

[0042] Combine Figure 1 、 Figure 2 and Figure 5 As shown, the fixed-distance rotary machine 1 also includes multiple shaft end limiting mechanisms 13, and the shaft end limiting mechanism 13 is provided with at least one at each end of the square shaft 100 and the pentagonal shaft 200. The shaft end limiting mechanism 13 includes a limiting member 131 for contacting the end faces of the square shaft 100 and the pentagonal shaft 200.

[0043] Specifically, the shaft end limiting mechanism 13 is arranged at both ends of the square shaft 100 and the pentagonal shaft 200, and at least one is provided at each end of the square shaft 100 or the pentagonal shaft 200. In one embodiment, the limiting member 131 contacts the end faces of the square shaft 100 and the pentagonal shaft 200 in a sliding friction contact manner. The limiting member 131 can be a slider that is in sliding contact with the end faces of the square shaft 100 and the pentagonal shaft 200. In this way, when the square shaft 100 and the pentagonal shaft 200 rotate, the two end faces of the square shaft 100 and the pentagonal shaft 200 are in sliding contact with the slider, thereby achieving the axial limiting effect on the square shaft 100 and the pentagonal shaft 200. However, due to the large friction loss caused by the sliding contact, the slider needs to be promptly and regularly moved. Replacement is not practical; in one embodiment, the contact between the limit member 131 and the end faces of the square shaft 100 and the pentagonal shaft 200 is rolling friction contact. For example, the limit member 131 is a guide wheel, and the square shaft 100 and the pentagonal shaft 200 contact the guide wheel and roll the guide wheel during rotation. Compared with the sliding friction contact, the rolling friction contact has low resistance and low friction loss, so that the guide wheel can maintain a reasonable contact force with the end faces of the square shaft 100 and the pentagonal shaft 200 for a long time, and thus can maintain the axial limiting effect of the square shaft 100 and the pentagonal shaft 200 for a long time, thereby eliminating the axial movement problem of the square shaft 100 and the pentagonal shaft 200 during rotation, and ensuring the rotation accuracy of the square shaft 100 and the pentagonal shaft 200.

[0044] Combine Figure 1 、 Figure 2 and Figure 5 As shown, the limiting member 131 is a guide wheel, which is rotatably sleeved on a guide wheel shaft 132 , and the guide wheel shaft 132 is fixedly connected to the limiting member mounting seat 133 .

[0045] Specifically, the limit member mounting seat 133 can be fixed to the ground through a bracket, the limit member mounting seat 133 can also be fixed on the support seat 22, and the limit member 131 can also be a rigid rolling ball, so that the rigid rolling ball can be embedded in the rolling cavity of the limit member mounting seat 133, and the rigid rolling ball can also achieve the same effect as the guide wheel. When the four-corner shaft 100 and the five-corner shaft 200 are rotating, the guide wheel and the rigid rolling ball can roll in contact with the end faces of the four-corner shaft 100 and the five-corner shaft 200, thereby achieving a limiting effect.

[0046] Combine Figure 1 、 Figure 2 and Figure 3 As shown, the supporting roller 111 and the guide wheel are both rolling bearings.

[0047] Specifically, the inner ring of the rolling bearing is mounted on the shaft, while the outer ring of the rolling bearing contacts the circumference or end face of the square shaft 100 or the pentagonal shaft 200. The rolling bearing not only provides excellent support but also keeps the square shaft 100 or the pentagonal shaft 200 in a normal operating position, improving rotational accuracy during operation. The rolling bearing is also easy to install and remove, making it convenient to remove the fixed-distance rotary machine 1 from the square shaft 100 or the pentagonal shaft 200.

[0048] Combine Figure 1 、 Figure 2 and Figure 3 As shown, the constant speed ratio drive mechanism 2 includes a transmission assembly 21, which includes a square shaft transmission wheel 213 for being mounted on the end of the square shaft 100, a pentagonal shaft transmission wheel 211 for being mounted on the end of the pentagonal shaft 200, and a power input wheel 212 for driving the square shaft transmission wheel 213 to rotate synchronously with the pentagonal shaft 200.

[0049] Combine Figure 1 、 Figure 2 and Figure 3 As shown, the four-axis transmission wheel 213, the five-axis transmission wheel 211 and the power input wheel 212 are all gears, the power input wheel 212 is located between the four-axis transmission wheel 213 and the five-axis transmission wheel 211, and the power input wheel 212 is meshed with the four-axis transmission wheel 213 and the five-axis transmission wheel 211.

[0050] Specifically, first, the gear serving as the power input wheel 212 is mounted on one end of the coupling by means of a key connection, and the other end of the coupling is mounted on the output shaft of the servo motor 24. Gears with a fixed gear ratio are mounted on the square shaft transmission wheel 213 and the pentagonal shaft transmission wheel 211, respectively. The gears are fixed to the square shaft 100 and the pentagonal shaft 200 by means of a key connection, and the gears serving as the square shaft transmission wheel 213 and the pentagonal shaft transmission wheel 211 are adjusted to a state where they mesh with the gear serving as the power input wheel 212. By presetting the transmission speed ratio of the servo motor 24, the gear serving as the power input wheel 212 drives the gears serving as the four-angle shaft transmission wheel 213 and the five-angle shaft transmission wheel 211 to rotate according to a predetermined speed ratio. When installing the four-angle disk scraper and the five-angle disk scraper, the rotation angles of the four-angle shaft 100 and the five-angle shaft 200 can be known in real time. There is no need to adopt the manual marking positioning method. Accurate positioning can be achieved when installing the four-angle shaft scraper and the five-angle shaft scraper to prevent the four-angle disk scraper and the five-angle disk scraper from interfering with each other in rotation.

[0051] In this embodiment, the transmission component 21 can use a sprocket combination instead of gears; sprockets with fixed tooth ratios are respectively installed on the square shaft 100 and the pentagonal shaft 200, and a driving sprocket is installed on the base. According to the size of the wrap angle, an adjustment sprocket is installed at an appropriate position, and the square shaft 100 and the pentagonal shaft 200 are driven by the chain to rotate according to the speed ratio. The sprocket structure is particularly suitable for use in a structure with adjustable spacing of the support wheel group 11; in another embodiment, the transmission component 21 can also use a synchronous belt instead of gears, and synchronous pulleys with fixed tooth ratios are respectively installed on the square shaft 100 and the pentagonal shaft 200, and a driving synchronous pulley is installed on the base. According to the size of the wrap angle, an adjustment synchronous pulley is installed at an appropriate position, and the square shaft 100 and the pentagonal shaft 200 are driven by the synchronous belt to rotate according to the speed ratio.

[0052] Combine Figure 1 、 Figure 2 and Figure 3 As shown, the constant speed ratio drive mechanism 2 also includes a support seat 22 and an angular displacement sensor 23 fixedly connected to the support seat 22. The angular displacement sensor 23 is used to detect the rotation angle of the four-angle shaft 100 and the pentagonal shaft 200. The support seat 22 includes a side support seat 221 for supporting the four-angle shaft transmission wheel 213 and the pentagonal shaft transmission wheel 211 and a middle support seat 222 for supporting the power input wheel 212. The four-angle shaft transmission wheel 213 and the pentagonal shaft transmission wheel 211 are respectively rotatably connected to the side support seat 221 through a wheel shaft 214, and the power input wheel 212 is rotatably connected to the middle support seat 222 through another wheel shaft 214. The power input wheel 212 is fixedly connected to the output shaft of the servo motor 24.

[0053] Specifically, two modes of driving can be adopted: servo motor 24 driving and manual driving. In the servo motor 24 driving mode, it can drive the four-angle shaft 100 and the five-angle shaft 200 to rotate, thereby achieving the purpose of accurately controlling the speed ratio and accurately controlling the rotation angle. In the manual driving mode, the angular displacement sensor 23 is used as a precise control method. The angular displacement sensor 23 is used to monitor the rotation angle of the four-angle shaft 100 and the five-angle shaft 200 in real time. Accurate positioning can be achieved when installing the four-angle shaft scraper and the five-angle shaft scraper, and the scraper that causes interference can also be accurately positioned during subsequent test runs.

[0054] In this embodiment, the angular displacement sensor 23 can be installed on the ground using a bracket, or it can be fixed to the support base 22 by screws. The probe of the angular displacement sensor 23 can be fixed to the four-corner shaft 100 and the five-corner shaft 200 whose rotation angle needs to be detected by using a nylon sleeve and a fastening screw. However, the four-corner shaft 100 and the five-corner shaft 200 whose rotation angle needs to be detected need to be parallel to the ground. The probe of the angular displacement sensor 23 rotates together with the four-corner shaft 100 and the five-corner shaft 200 to be measured. That is to say, when the driving mode of the servo motor 24 cannot work, the manual driving mode is adopted and the angular displacement sensor 23 is used to monitor the rotation angle of the four-corner shaft 100 and the five-corner shaft 200 in real time, which can also ensure the precise positioning effect when installing the four-corner shaft scraper and the five-corner shaft scraper.

[0055] Combine Figure 6 、 Figure 7 and Figure 8 As shown, the present invention also provides an installation device for a stirring shaft (hereinafter referred to as the installation device), including a self-centering traveling frame 3 and a fixed-distance rotary machine 1 in the manufacturing device of the stirring shaft as mentioned above, the fixed-distance rotary machine 1 is used to be arranged at one end of the square shaft 100 and the pentagonal shaft 200, the self-centering traveling frame 3 includes a traveling frame body 31 and a self-centering wheel 32 arranged on the traveling frame body 31, the traveling frame body 31 is used to be detachably connected to the other end of the square shaft 100 and the pentagonal shaft 200, the self-centering wheel 32 is used to roll in contact with the inner wall of the shell 300, when the self-centering wheel 32 moves axially along the shell 300, the axis of the square shaft 100 and the axis of the pentagonal shaft 200 are symmetrical about the axis of the shell 300, and the axis of the square shaft 100, the axis of the pentagonal shaft 200 and the axis of the shell 300 are coplanar.

[0056] Specifically, the shape of the self-centering walking frame 3 is determined according to the shape of the shell 300. In this embodiment, the inner wall of the shell 300 is in the shape of a "heart". At this time, the walking frame body 31 in the self-centering walking frame 3 is also in the shape of a "heart". The self-centering wheel 32 is installed on the outer peripheral side of the walking frame body 31, and when the walking frame body 31 moves along the axis of the shell 300, the self-centering wheel 32 can just move on the "heart"-shaped inner wall of the shell 300. When the inner wall of the shell 300 is in other shapes, the walking frame body 31 is processed into a shape that matches the inner wall of the shell 300 according to actual needs, so that the automatic centering function can be realized, thereby preventing the agitator shaft from deviating during the walking process and ensuring the accuracy of the agitator shaft after being assembled to the shell 300.

[0057] In this embodiment, the self-centering wheel 32 can be replaced by a rigid ball, and the rigid ball can be embedded in the rolling cavity opened on the outer peripheral side of the walking frame 31, so that the rigid ball can also roll on the inner wall of the shell 300, thereby achieving the automatic centering function. The shell 300 can also be a mixing container such as a kettle body, a tank body, or a cylinder body.

[0058] Combine Figure 6 、 Figure 7 and Figure 8 As shown, the self-centering walking frame 3 also includes a walking wheel 34, and the walking wheel 34 and the self-centering wheel 32 are both rotatably connected to the walking frame body 31. The walking wheel 34 is used for rolling contact with the inner wall of the shell 300. The self-centering walking frame 3 also includes a clamp 33, and the clamp 33 is used to fix the walking frame body 31 to the square shaft 100 and the pentagonal shaft 200.

[0059] In this example, when the agitator shaft is installed into the shell 300, one end of the agitator shaft is first fixed to the traveling frame 31 with a clamp 33 to prevent the agitator shaft from moving. The other end of the agitator shaft is installed on the fixed-distance rotary machine 1, and then the agitator shaft is lifted as a whole, and the traveling frame 31 is installed into the shell 300. It relies on the traveling wheels 34 to move in the shell 300, and the self-centering wheels 32 move on the inner wall of the shell 300. When the agitator shaft is in place, the fixed-distance rotary machine 1 and the self-centering traveling frame 3 are removed from the square shaft 100 and the pentagonal shaft 200 to complete the process of installing the agitator shaft to the shell 300. The installation device includes the fixed-distance rotary machine 1 in the manufacturing device. When installing the agitator shaft, the fixed-distance rotary machine 1 can ensure the stability of the precision of the square shaft 100 and the pentagonal shaft 200 in the agitator shaft, so as to achieve the effect of cooperating with the self-centering traveling frame 3 to install the agitator shaft.
