Description

Technical Field

[0001] This invention relates to the field of liquid packaging equipment technology, and more specifically to a method for processing a rotary support for a bottle rinsing machine. Background Technology

[0002] During the filling process, containers used for filling materials need to be sterilized with a high-temperature disinfectant solution before being rinsed with clean water. The bottle rinsing machine is used to sterilize and clean these containers. When the bottle rinsing machine is working, a high-temperature disinfectant solution is continuously sprayed onto the machine frame surface. The temperature of this disinfectant solution is typically between 55℃ and 75℃. This temperature can easily cause the machine frame to deform due to heat. This results in horizontal and vertical displacement of the working surface of the station where the container holders are installed on the machine frame. Consequently, the container holders shift horizontally and vertically, leading to misalignment between the bottle rinsing machine and the mechanisms at adjacent stations at the container handover point. Ultimately, this can cause containers to fall or their openings to be damaged during handover, impacting production efficiency and reducing packaging quality.

[0003] To overcome the technical problem of displacement in bottle rinsing machines under high temperatures, the current production process requires adjusting the installation position of the container holders on the bottle rinsing machine to ensure smooth container handover between the machine and adjacent workstations at high temperatures. However, different disinfectants have different operating temperatures, necessitating adjustments to the container holders' position when using different disinfectants for high-temperature sterilization to accommodate deformation of the bottle rinsing machine at varying temperatures. Furthermore, adjusting the container holders' position is required when debugging the machine at room temperature. This makes the current bottle rinsing machine time-consuming and labor-intensive during production, maintenance, and installation, reducing production efficiency and significantly increasing labor and maintenance costs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a processing method for the heat-resistant deformation of the rotary support of a bottle rinsing machine. This method reduces the average deformation of the working surface after heating by improving the structure of the rotary support. On the other hand, the improved rotary support is modeled in finite element analysis software, and then thermodynamic analysis is performed. After predicting the deformation, the structure and assembly position of the improved rotary support are further adjusted in the model through a first adjustment method and a second adjustment method to further overcome the possible deformation of the working surface, thereby ensuring that the bottle rinsing machine always maintains a good working condition under different high-temperature working environments.

[0005] To solve the above problems, the technical solution adopted by the present invention is: a processing method for heat-resistant deformation of a rotary support for a bottle rinsing machine, comprising: 1. Designing an initial rotary support, the structure of which includes: a rotary body, the rotary body comprising two coaxial and parallel disks of the same shape, a plurality of identical support members disposed between the two disks, the number of support members being even and evenly spaced along the circumference of the disks, the top and bottom of each support member being welded and fixed to the two disks respectively, the lower disk being rotatably supported on a bearing seat, a feeding support mechanism disposed on the outer side of the rotary body, the feeding support mechanism comprising: a horizontally arranged annular feeding plate, the annular plate surface of the outer ring of the feeding plate being a working surface for spaced installation of container clamps, an annular reinforcing ring welded and fixed to the inner side of the feeding plate, the plate surface of the reinforcing ring being perpendicular to the plate surface of the feeding plate, the feeding plate and the reinforcing ring being coaxial with the rotary body; each support member being connected to the reinforcing ring. A reinforcing rib is provided, and each reinforcing rib is arranged radially along the rotating body. The inner end of each reinforcing rib is welded and fixed to the outer side of the corresponding support and the upper and lower discs. The outer end of each reinforcing rib is welded and fixed to the inner wall of the reinforcing ring. The plane at the center height of the rotating body and parallel to the two discs is designated as the plane of symmetry. The feeding plate and reinforcing ring in the feeding support mechanism are centered in the height direction about the plane of symmetry. The welded part between the reinforcing ring and the reinforcing rib is the binding area. The binding area above the plane of symmetry is the upper binding area, and the binding area below the plane of symmetry is the lower binding area. The upper and lower binding areas between each reinforcing rib and the reinforcing ring of the initial rotating support are symmetrically arranged about the plane of symmetry. The part of each reinforcing rib above the plane of symmetry is the upper area of ​​the reinforcing rib, and the part below the plane of symmetry is the lower area of ​​the reinforcing rib. The upper and lower areas of each reinforcing rib are symmetrically arranged about the plane of symmetry. 2. Model the initial rotating support of the above structure in finite element analysis software. Apply external force load according to the weight of the container holder. According to the temperature environment in the bottle rinsing machine production process, add corresponding working temperatures to the rotating body area, reinforcing rib area and feeding support mechanism area of ​​the initial rotating support. Perform simulation analysis to obtain the initial vertical deformation direction of the working surface in the height direction and the initial average vertical deformation of the working surface. 3. The first adjustment method is to adjust the distribution of each restraint zone in the height direction about the plane of symmetry; the second adjustment method is to adjust the mass distribution of each reinforcing rib about the plane of symmetry. IV. Implementing the first adjustment method separately: If the initial vertical deformation direction of the working face is downward and the initial average vertical deformation of the working face exceeds the allowable deformation range, adjust the distribution of each restraint zone about the plane of symmetry in the height direction so that the length of each lower restraint zone is less than the length of the corresponding upper restraint zone, and perform thermodynamic deformation analysis. If the initial vertical deformation direction of the working face is still downward and the average vertical deformation of the working face still exceeds the allowable deformation range, continue to adjust the distribution of the restraint zones about the plane of symmetry in the height direction so that the length of each lower restraint zone is further less than the length of the corresponding upper restraint zone, and perform thermodynamic deformation analysis again. Repeat this process until the average vertical deformation of the working face is within the allowable deformation range. If the initial vertical deformation direction of the working face is upward and the average vertical deformation of the working face exceeds the allowable deformation range, then adjust the distribution of each restraint zone about the plane of symmetry in the height direction so that the length of each lower restraint zone is greater than the length of the corresponding upper restraint zone, and then perform thermodynamic deformation analysis. If the vertical deformation direction of the working face is still upward and the average vertical deformation of the working face still exceeds the allowable deformation range, then continue to adjust the distribution of each restraint zone about the plane of symmetry in the height direction so that the length of each lower restraint zone is further greater than the length of the corresponding upper restraint zone, and then perform thermodynamic deformation analysis. Repeat this process until the average vertical deformation of the working face is within the allowable deformation range. Alternatively, a second method for adjusting the deformation can be implemented separately: If the initial vertical deformation direction of the working surface is downward and the initial average vertical deformation of the working surface exceeds the allowable deformation range, then adjust the mass distribution of each reinforcing rib plate about the plane of symmetry so that the mass of the upper region of each reinforcing rib plate is greater than the mass of the corresponding lower region of the reinforcing rib plate. Then perform thermodynamic deformation analysis. If the initial vertical deformation direction of the working surface is still downward and the average vertical deformation still exceeds the allowable deformation range, then continue to adjust the mass distribution of each reinforcing rib plate about the plane of symmetry so that the mass of the upper region of each reinforcing rib plate is further greater than the mass of the corresponding lower region of the reinforcing rib plate. Then perform thermodynamic deformation analysis again. Repeat this process until the average vertical deformation of the working surface is within the allowable deformation range. If the initial vertical deformation direction of the working face is upward and the initial vertical deformation exceeds the allowable deformation range, adjust the mass distribution of each reinforcing rib plate about the plane of symmetry so that the mass of the upper region of each reinforcing rib plate is less than the mass of the lower region of the corresponding reinforcing rib plate. Then perform thermodynamic deformation analysis. If the initial vertical deformation direction of the working face is still upward and the average vertical deformation still exceeds the allowable deformation range, continue to adjust the mass distribution of each reinforcing rib plate about the plane of symmetry so that the mass of the upper region of each reinforcing rib plate is further less than the mass of the lower region of the corresponding reinforcing rib plate. Then perform thermodynamic deformation analysis again. Repeat this process until the average vertical deformation of the working face is within the allowable deformation range. Alternatively, the adjustment can be performed using a combination of the first and second adjustment methods. For example, if the initial vertical deformation direction of the working surface is downward and the average vertical deformation of the working surface exceeds the allowable deformation range, the distribution of each restraint zone in the height direction about the plane of symmetry is adjusted so that the length of the lower restraint zone is less than the length of the corresponding upper restraint zone. The distribution of the mass of each reinforcing rib plate about the plane of symmetry is also adjusted so that the mass of the upper region of each reinforcing rib plate is greater than the mass of the lower region of the corresponding reinforcing rib plate. Then, a thermodynamic deformation analysis is performed. If the vertical deformation direction of the working surface is still downward and the average vertical deformation of the working surface still exceeds the allowable deformation range, the adjustment continues until the length of the lower restraint zone is further less than the length of the upper restraint zone and / or the mass of the upper region of each reinforcing rib plate is further greater than the mass of the lower region of each reinforcing rib plate. Then, a thermodynamic deformation analysis is performed again. If the vertical deformation direction of the working surface is still downward and the average vertical deformation still exceeds the allowable deformation range, the adjustment continues until the average vertical deformation of the working surface is within the allowable deformation range. If the initial vertical deformation direction of the working face is upward and the initial average vertical deformation of the working face exceeds the allowable deformation range, adjust the distribution of each restraint zone about the plane of symmetry in the height direction so that the length of each lower restraint zone is greater than the length of the corresponding upper restraint zone, and adjust the mass distribution of each reinforcing rib about the plane of symmetry so that the mass of the upper region of each reinforcing rib is less than the mass of the lower region of the corresponding reinforcing rib. Then perform thermodynamic deformation analysis. If the vertical deformation direction of the working face is still upward and the average vertical deformation still exceeds the allowable deformation range, continue to adjust so that the length of the lower restraint zone is further greater than the length of the upper restraint zone and / or the mass of the upper region of each reinforcing rib is further less than the mass of the lower region of each reinforcing rib. Then perform thermodynamic deformation analysis again. If the vertical deformation direction of the working face is still downward and the average vertical deformation still exceeds the allowable deformation range, continue to adjust until the average vertical deformation of the working face is within the allowable deformation range. 5. Process each component according to the model dimensions adjusted in step 4, and then install them according to the installation positions of the model adjusted in step 4 to form the finished rotating bracket.

[0006] Furthermore, in the aforementioned processing method for heat-resistant deformation of a rotary support for a bottle rinsing machine, in the fourth step, the mass distribution of each reinforcing rib plate about the plane of symmetry is adjusted so that the mass of the upper region of each reinforcing rib plate is greater than the mass of the lower region of each reinforcing rib plate. Specifically, this involves cutting the plate body of the lower region of each reinforcing rib plate so that the mass of the upper region of each reinforcing rib plate is greater than the mass of the corresponding lower region of the reinforcing rib plate; and the mass distribution of each reinforcing rib plate about the plane of symmetry is adjusted so that the mass of the upper region of each reinforcing rib plate is less than the mass of the lower region of each reinforcing rib plate. Specifically, this involves cutting the plate body of the upper region of each reinforcing rib plate so that the mass of the upper region of each reinforcing rib plate is less than the mass of the corresponding lower region of the reinforcing rib plate.

[0007] Furthermore, in the aforementioned processing method for heat-resistant deformation of the rotary support of a bottle rinsing machine, when adjusting the mass distribution of each reinforcing rib about the plane of symmetry, the mass of each adjustment is 0.1 kg to 0.5 kg.

[0008] Furthermore, in the aforementioned processing method for heat-resistant deformation of a rotary support for a bottle rinsing machine, in the fourth step, the distribution of the restraint area about the plane of symmetry in the height direction can be adjusted by moving the supply support mechanism up and down to change the distribution of the restraint area about the plane of symmetry, or by cutting the ends of the reinforcing ribs above or below the plane of symmetry at the welding position with the reinforcing ring to change the distribution of the restraint area about the plane of symmetry.

[0009] Furthermore, in the aforementioned processing method for heat-resistant deformation of a rotary support for a bottle rinsing machine, in the fourth step, the distribution of the restraint area about the plane of symmetry in the height direction is adjusted by cutting the ends of the reinforcing ribs above or below the plane of symmetry at the welding positions with the reinforcing ring, thereby changing the distribution of the restraint area about the plane of symmetry.

[0010] Furthermore, in the aforementioned processing method for heat-resistant deformation of the rotary support of a bottle rinsing machine, when cutting the ends of the reinforcing ribs above or below the plane of symmetry and at the welding position with the reinforcing ring, each cut begins at the top or bottom of the end of the reinforcing rib, and the height of each cut is 0.1 mm to 1 mm, and the mass is 0.001 kg to 0.02 kg.

[0011] Furthermore, in the aforementioned processing method for heat-resistant deformation of a rotary support for a bottle rinsing machine, when the vertical average deformation of the working surface is less than or equal to 0.1 mm from the allowable range of vertical deformation, the distribution of the restraint area in the height direction about the plane of symmetry is fine-tuned and / or the mass distribution of each reinforcing rib about the plane of symmetry is fine-tuned. The height of each fine-tuning of the distribution of the restraint area in the height direction about the plane of symmetry is 0.1 mm to 0.3 mm, and the mass is 0.001 kg to 0.005 kg. The mass distribution of each reinforcing rib about the plane of symmetry is fine-tuned, and the mass of each fine-tuning is 0.1 kg to 0.2 kg.

[0012] Furthermore, in the aforementioned processing method for heat-resistant deformation of the rotary support of a bottle rinsing machine, the gravity load of the container holder is applied by calculating the sum of the gravity of all container holders and then applying it to the working surface in a uniformly distributed manner.

[0013] Furthermore, in the aforementioned processing method for heat-resistant deformation of the rotary support of a bottle rinsing machine, the sum of the weights of all container holders is multiplied by a safety factor, and then a uniformly distributed load is applied to the working surface, with a safety factor of 1.2 to 2.5.

[0014] Furthermore, in the aforementioned processing method for heat-resistant deformation of a rotary support for a bottle rinsing machine, in the initial rotary support, reinforcing ribs are symmetrically welded to both sides of the plate body located at the height of the symmetrical plane.

[0015] Furthermore, in the aforementioned processing method for heat-resistant deformation of the rotary support of a bottle rinsing machine, each reinforcing rib plate in the initial rotary support has an upper inclined edge that gradually slopes downward from the support member toward the reinforcing ring at its top, and each reinforcing rib plate has a lower inclined edge that gradually slopes upward from the support member toward the reinforcing ring at its bottom, with the upper and lower inclined edges being symmetrical about the symmetrical plane.

[0016] Furthermore, in the aforementioned processing method for heat-resistant deformation of a rotary support for a bottle rinsing machine, in the initial rotary support, each reinforcing rib plate has a top straight edge connected to a top inclined edge, and each reinforcing rib plate has a bottom straight edge connected to a bottom inclined edge. The top straight edge and the bottom straight edge are located near one end of the support member.

[0017] Furthermore, in the aforementioned processing method for heat-resistant deformation of a rotary support for a bottle rinsing machine, each support component comprises: a support body, both sides of which are bent inwards and toward the center of the disc, with the same angle and length of bending inwards and toward the center of the disc on both sides of the support body; and the inner end of the reinforcing rib is welded to the outer wall of the support body.

[0018] Furthermore, in the aforementioned processing method for heat-resistant deformation of a rotary support for a bottle rinsing machine, in the second step, the working temperature applied to the rotary body position area of ​​the initial rotary support is 25℃~35℃, the working temperature applied to the reinforcing rib position area is 35℃~55℃, and the working temperature applied to the support mechanism position area is 55℃~75℃.

[0019] The advantages of this invention are: 1. A novel rotary support for a bottle rinsing machine has been developed. This rotary support exhibits good structural symmetry relative to the plane of symmetry, effectively reducing thermal deformation. 2. By utilizing thermodynamic simulation analysis, the amount of thermal deformation is further adjusted, thereby further refining the shape of the rotary support to obtain the final structure. This method is simple, effectively saves manufacturing costs, and controls the vertical deformation within the required range, thus greatly improving the reliability and stability of the container transfer process during filling production, and consequently, effectively increasing production efficiency.

[0027] The following detailed description, in conjunction with the accompanying drawings and preferred embodiments, provides a further explanation of the processing method for heat-resistant deformation of a rotary support for a bottle rinsing machine according to the present invention.

[0028] A method for processing a rotary support for a bottle rinsing machine to resist thermal deformation includes the following four main steps.

[0029] I. Design the initial rotary support. For example... Figure 1 , Figure 2 , Figure 3 As shown, the initial rotating support structure includes: a rotating body 1, which includes two coaxial and parallel disks of the same shape—an upper disk 11 and a lower disk 12. Several identical support members 13 are arranged between the two disks, with an even number of support members 13 evenly spaced along the circumference of the disks. The top and bottom of each support member 13 are welded and fixed to the upper disk 11 and the lower disk 12, respectively. The lower disk 12, which is located below, is rotatably supported on a bearing seat 2.

[0030] A feeding support mechanism 3 is provided on the outer side of the rotating body 1. The feeding support mechanism 3 includes an annular feeding plate 31 with its surface horizontally arranged. The annular surface of the outer ring of the feeding plate 31 is a working surface for installing container holders 4 at intervals. An annular reinforcing ring 32 is welded and fixed to the inner side of the feeding plate 31. The surface of the reinforcing ring 32 is perpendicular to the surface of the feeding plate 31. Both the feeding plate 31 and the reinforcing ring 32 are coaxial with the rotating body 1.

[0031] A reinforcing rib plate 5 is provided between each support member 13 and the reinforcing ring 32. Each reinforcing rib plate 5 is arranged radially along the rotating body 1. The inner end of each reinforcing rib plate 5 is welded and fixed to the outer side of the corresponding support member 13 and the two discs arranged above and below. The outer end face of each reinforcing rib plate 5 is welded and fixed to the inner wall of the reinforcing ring 32.

[0032] The plane at the center height of the rotating body 1, parallel to the two disks, is designated as the symmetry plane 100. The feeding plate 31 and reinforcing ring 32 in the feeding support mechanism 3 are symmetrically arranged in the height direction about the symmetry plane 100. To improve the stability of the connection, in this embodiment, reinforcing ribs 6 are symmetrically welded to both sides of each reinforcing rib plate 5 at the height of the symmetry plane 100.

[0033] In this embodiment, each reinforcing rib plate 5 has a top straight edge 511 and a top inclined edge 512, and a bottom straight edge 521 and a bottom inclined edge 522. The top straight edge 511 and the bottom straight edge 521 are located near the support member 13. The top inclined edge 512 gradually slopes downward from the support member 13 towards the reinforcing ring 32, and the bottom inclined edge 522 gradually slopes upward from the support member 13 towards the reinforcing ring 32. The top straight edge 511 and the bottom straight edge 521 of each reinforcing rib plate 5 are symmetrically arranged about the plane of symmetry 100, and the top inclined edge 512 and the bottom inclined edge 522 of each reinforcing rib plate 5 are also symmetrically arranged about the plane of symmetry 100. The arrangement of the top inclined edge 512 and the bottom inclined edge 522 can effectively reduce the weight of the entire rotating bracket, and the arrangement of the top straight edge 511 and the bottom straight edge 521 greatly facilitates the welding and fixing of the reinforcing rib plate 5 to the upper disc 11 and the lower disc 12. The portion of each reinforcing rib plate 5 located above the symmetry plane 100 is the upper region 501 of the reinforcing rib plate, and the portion located below the symmetry plane 100 is the lower region 502 of the reinforcing rib plate. Both the upper region 501 and the lower region 502 of each reinforcing rib plate 5 are symmetrically arranged about the symmetry plane 100.

[0034] In this embodiment, each support member 13 includes a support member body 131, with both sides of the support member body 131 bent inwards and towards the center of the disk, and the angle and length of the inward bending of both sides of the support member body 131 towards the center of the disk are the same; the inner end of the reinforcing rib 5 is welded to the outer wall of the support member body 131. This structural shape of the support member 13 increases the connection area with the upper disk 11 and the lower disk 12, thus greatly improving the connection reliability.

[0035] The dimensions of each component in this embodiment are as follows, see below. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 .

[0036] The upper disk 11 and the lower disk 12 have the same dimensions: outer diameter 1760mm, inner diameter 1400mm, and thickness 30mm.

[0037] Support component 13: Height 491mm, plate thickness t1=16mm, bending angle θ on both sides is 120°; cross-sectional length L1=270mm, width D1=200mm.

[0038] The reinforcing rib plate 5 is approximately trapezoidal in shape, with a length L2 = 485 mm, an outer end height H2 = 95 mm, an inner end height H3 = 491 mm, and a plate thickness of 30 mm. The top straight edge L3 equals the bottom straight edge L4 = 80 mm, the top inclined edge L5 = 446.8 mm, and the bottom inclined edge L6 = 446.8 mm. The height of the upper restraint zone between each reinforcing rib plate 5 and the reinforcing ring 32 equals the height of the lower restraint zone = 47.5 mm. Figure 5 In the middle, α = 155°.

[0039] The length of the reinforcing rib 6 is 485mm, the width is 50mm, and the plate thickness is 20mm; Reinforcing ring 32: outer diameter 2570mm, inner diameter 2620mm, height 120mm.

[0040] Dispensing plate 31: Inner diameter 2620mm, outer diameter 2890mm, thickness 25mm; All of the above components are made of SUS304 stainless steel, and the total mass of the initial rotating support is 1500kg.

[0041] Each container holder 4 weighs 5 kg, and a total of 90 container holders 4 are installed.

[0042] 2. The initial rotating support of the above structure is modeled in finite element analysis software. Gravity load is applied according to the weight of the initial rotating support. External force load is applied at the working surface of the station according to the weight and distribution position of the container holder 4. The corresponding working temperature is added to the rotating body position area, the reinforcing rib position area and the feeding support mechanism position area of ​​the initial rotating support according to the temperature environment in the bottle rinsing machine production process. Then, thermodynamic simulation analysis is performed to obtain the initial deformation direction and initial deformation amount of the working surface of the station in the height direction.

[0043] In this embodiment, the load is applied to the working surface based on the actual workload and heat distribution measurement data. The weight of a single container holder 4 is 50N, with a safety factor of 2.22, resulting in a total weight of 10000N, applied to the working surface as a uniformly distributed load. At a room temperature reference of 25℃, a temperature load of 65℃ is applied to the area of ​​the distribution support mechanism, including the distribution plate 31 and reinforcing ring 32; a temperature load of 55℃ is applied to the area of ​​the reinforcing ribs, including the reinforcing ribs 5 and reinforcing ribs 6; and a temperature load of 45℃ is applied to the area of ​​the rotating body, including the upper disc 11, lower disc 12, and support member 13. A fixed constraint is applied to the bottom of the lower disc 12.

[0044] Thermodynamic simulation analysis yielded the initial deformation direction and initial average deformation of the working surface. The vertical deformation direction is vertically downwards, with an average vertical deformation of 1.5 mm. Radial deformation also occurs, with an average radial deformation of 0.8 mm and a radial outward direction. Since radial deformation does not affect the container clamp's ability to transfer the container, it is ignored in this invention.

[0045] 3. The first adjustment method is to adjust the distribution of each restraint zone in the height direction about the plane of symmetry 100; the second adjustment method is to adjust the mass distribution of each reinforcing rib 5 about the plane of symmetry 100.

[0046] The first adjustment method described in this embodiment specifically refers to: changing the distribution of the restraint area about the plane of symmetry 100 by cutting the ends of the reinforcing ribs 5 above or below the plane of symmetry where they are welded to the reinforcing ring 32; in order to improve the accuracy of the adjustment, the height of each cut is 0.1 mm to 1 mm and the mass is 0.001 kg to 0.005 kg.

[0047] The second method for adjusting the deformation amount described in this embodiment specifically refers to adjusting the mass distribution of each reinforcing rib plate about the plane of symmetry, so that the mass of the upper region 501 of each reinforcing rib plate is greater than or less than the mass of the lower region 502 of each reinforcing rib plate. The specific steps are: cutting the plate body of the lower region 502 of each reinforcing rib plate so that the mass of the upper region 501 of each reinforcing rib plate is greater than the mass of the corresponding lower region 502, or cutting the plate body of the upper region 501 of each reinforcing rib plate so that the mass of the upper region 501 of each reinforcing rib plate is less than the mass of the corresponding lower region 502 of each reinforcing rib plate; to improve the accuracy of the adjustment, the mass of each adjustment is controlled within 0.1 kg to 0.5 kg. The cutting position of the upper region 501 of each reinforcing rib plate is not limited, nor is the cutting position of the lower region 502 of each reinforcing rib plate, but for convenience, the edge position is usually cut.

[0048] IV. In this embodiment, the adjustment is performed by combining the first adjustment method and the second adjustment method. The specific process is as follows.

[0049] The initial vertical deformation direction of the aforementioned working surface is vertically downward, and the average vertical deformation of the working surface is 1.5 mm. In this embodiment, the allowable deformation range is set to -0.050 mm to 0.05 mm, with vertically downward being positive. The allowable deformation range can be set according to actual needs.

[0050] First, adjust the distribution of each restraint zone about the plane of symmetry 100 in the height direction, so that the length of the lower restraint zone is less than the length of the corresponding upper restraint zone. Then, cut off the bottom of the reinforcing rib plate 5 below the plane of symmetry 100 where it is welded to the reinforcing ring 32. The first cut is 0.5 mm high and the cut mass is 0.01 kg. ， The length of the lower restraint zone is made smaller than the length of the upper restraint zone. Then, a thermodynamic deformation simulation analysis is performed. The vertical deformation of the working surface is still vertically downward, and the average vertical deformation is 1.2mm, which exceeds the allowable range of deformation. The above adjustment steps are repeated. When the total cutting height is 46mm, the thermodynamic deformation simulation analysis shows that the vertical deformation of the working surface is still vertically downward, and the average vertical deformation is 0.5mm, which still exceeds the allowable range of deformation. Therefore, a second adjustment method for deformation is performed.

[0051] The lower region 502 of each reinforcing rib is cut, such that the mass of the upper region 501 of each reinforcing rib is greater than the mass of the corresponding lower region 502. The mass of one cut is... 0.2kg, cut Afterwards, thermodynamic deformation simulation analysis was performed. The vertical deformation direction of the working surface was still vertically downward, and the average vertical deformation was 0.35mm, which exceeded the allowable deformation range. Therefore, the cutting was repeated. After each cutting, thermodynamic simulation analysis was performed. When the total mass reduction reached 2kg, the vertical deformation direction was still vertically downward, and the average vertical deformation was 0.12mm. At this time, fine adjustment was performed.

[0052] During fine-tuning, the first and second deformation adjustment methods are performed simultaneously. The specific steps are as follows: Each time, the bottom height of the reinforcing rib plate 5 at the welding position to the reinforcing ring 32 is reduced by 0.2 mm (mass 0.002 kg) below 100 mm of the symmetrical plane. Then, 0.1 kg of the plate body in the lower region 502 of each reinforcing rib plate is cut. After thermodynamic deformation simulation analysis, after 7 iterations, the average vertical deformation of the working surface is 0.03 mm, which is within the allowable range. The deformation adjustment is then complete.

[0053] The adjusted dimensions of each component are as follows: The dimensions, shapes, and installation positions of the upper disc 11, lower disc 12, support 13, and reinforcing rib 6 remain unchanged relative to the initial rotating bracket.

[0054] like Figure 6 As shown, the specific dimensions of the cut reinforcing rib plate 5 are: length L2 = 485mm, outer end height H2 = 47.5mm, inner end height H3 = 491mm, and plate thickness 30mm. Top straight edge L3 = bottom straight edge L4 = 80mm, top bevel L5 = 446.8mm, bottom bevel L61 = 171mm, bottom bevel L62 = 281mm, and L63 = 30mm. Figure 6In the equation, α = 155° and β = 166.5°.

[0055] The height of the upper restraint zone between each reinforcing rib plate 5 and reinforcing ring 32 is 47.5 mm; the height of the lower restraint zone between the reinforcing rib plate 5 and reinforcing ring 32 is 0 mm.

[0056] 5. Process each component according to the shape determined in step four, and install them according to the installation positions specified in step four. The rotating bracket is then formed, as shown below. Figure 7 As shown.

[0057] Materials possess the characteristic of uniformly expanding outwards when heated in a free state. Therefore, designing the initial rotating support as symmetrically as possible vertically relative to the symmetry plane 100 and around the rotation center can effectively reduce thermal deformation. However, because the bottom of the bottle rinsing machine's rotating support is supported and needs to rotate relative to the ground, the constraints of the rotating support cannot be perfectly symmetrical, and the influence of gravity also exists. Based on this, the present invention uses structural asymmetry to overcome the deformation caused by constraint asymmetry and gravity, thereby adjusting the vertical thermal deformation to within the allowable range.

[0058] The advantages of this invention are as follows: First, a novel rotary support for a bottle rinsing machine has been developed. This rotary support exhibits good structural symmetry relative to the symmetry plane 100, effectively reducing thermal deformation. Second, by utilizing thermodynamic simulation analysis, the amount of thermal deformation is further adjusted, thereby further refining the shape of the rotary support to obtain the final structure. This method is simple, effectively saves manufacturing costs, and controls the vertical deformation within the required range, thus greatly improving the reliability and stability of the container transfer process during filling production, and consequently, effectively increasing production efficiency.
