[0029] The specific embodiment of the utility model is explained in detail below in combination with the drawings.

[0030] REFERENCE Figures 1-3 The utility model discloses a coating rotary frame, including frame body, guide rail and positioning assembly 3.

[0031] Among them, the upper and lower ends of frame body are equipped with rotating disc, including the upper rotating disc 1 (upper disc) of being equipped with on the top of frame body, and the lower rotating disc 2 (lower disc) of being equipped with on the bottom of frame body.Frame body is set to be able to rotate horizontally around the vertical direction of rotating center.The upper rotating disc 1 and the lower rotating disc 2 are horizontally arranged on the frame body.

[0032] Guide rail includes the first guide rail 12 of being equipped with on the upper rotating disc 1, and the second guide rail 9 of being equipped with on the lower rotating disc 2.And, the first guide rail 12 is along the rotating circumferential direction of frame body and is equipped with on the upper rotating disc 1, and the second guide rail 9 is along the rotating circumferential direction of frame body and is equipped with on the lower rotating disc 2.Rotating circumferential direction is the circumferential direction of the circle with the rotating center of frame body as the center.

[0033] Positioning assembly 3 is multiple.Each positioning assembly 3 includes 1 first positioning part 33 and 1 second positioning part 34;First positioning part 33 is equipped on the edge of the upper rotating disc 1, and the second positioning part 34 is equipped on the edge of the lower rotating disc 2, and the first positioning part 33 and the second positioning part 34 are vertically arranged in pairs, for vertically clamping hanging rod 4 between the first positioning part 33 and the second positioning part 34.Hanging rod 4 is equipped with clamp 41 (only for example in the drawing) on it, for hanging the processing object (product) to be coated. Figure 1

[0034] ​The plurality of positioning assemblies 3 are evenly arranged along the rotation circumferential direction, i.e., each first positioning part 33 in the plurality of positioning assemblies 3 is evenly arranged on the edge of the upper turntable 1 along the rotation circumferential direction, and each second positioning part 34 in the plurality of positioning assemblies 3 is evenly arranged on the edge of the lower turntable 2 along the rotation circumferential direction.

[0035] Among the plurality of positioning assemblies 3, there is one first positioning assembly 31 and at least one second positioning assembly 32; each first positioning assembly 31 and each second positioning assembly 32 comprises one first positioning part 33 and one second positioning part 34.

[0036] The first positioning part 33 of the first positioning assembly 31 is fixedly arranged on the upper turntable 1, and the second positioning part 34 of the first positioning assembly 31 is fixedly arranged on the lower turntable 2.

[0037] The first positioning part 33 of the second positioning assembly 32 is slidingly fitted on the first guide rail 12, and the second positioning part 34 of the second positioning assembly 32 is slidingly fitted on the second guide rail 9. According to the preset number of the hanging rods 4, the second positioning assembly 32 determines the arrangement position in the rotation circumferential direction by taking the fixedly arranged first positioning assembly 31 as a positioning reference benchmark and is fastened. That is, the first positioning part 33 of the second positioning assembly 32 determines the arrangement position (circumferential angle position) in the rotation circumferential direction by taking the first positioning part 33 of the fixedly arranged first positioning assembly 31 as a benchmark, then moves along the first guide rail 12 to the arrangement position and is fastened on the upper turntable 1; and the second positioning part 34 of the second positioning assembly 32 determines the arrangement position in the rotation circumferential direction by taking the second positioning part 34 of the fixedly arranged first positioning assembly 31 as a benchmark, then moves along the second guide rail 9 to the arrangement position and is fastened on the lower turntable 2.

[0038] For example, when it is determined that 4 hangers 4 can be arranged on the rotating frame according to the size of a certain processing object, the position of the fixedly arranged first positioning assembly 31 is taken as the 0-degree position on the circumference, 3 second positioning assemblies 32 are determined at positions that are 90 degrees apart in sequence on the circumference, and are moved to the corresponding positions along the guide rail and then fastened on the rotating disc, so that 4 positioning assemblies 3 (including 1 first positioning assembly 31 and 3 second positioning assemblies 32) are arranged on the circumference at intervals of 90 degrees.

[0039] The conventional rotating frame is a fixed rotating frame, and in order to adapt to products of different sizes and specifications, different types of rotating frames are usually required, and each rotating frame can only accommodate products of a specific size and quantity. If the type and size of the product change, a rotating frame that matches the product needs to be used. The disadvantage of such a fixed rotating frame is that multiple rotating frames occupy a large amount of storage and operation space, increasing the burden of warehousing and transportation and leading to an increase in costs, and the process of replacing the rotating frame is time-consuming and labor-intensive, increasing the operation time and labor cost and reducing the production efficiency. In addition, the conventional fixed rotating frame cannot adjust the position of the hanger according to the product demand, cannot meet the changing production demand, and has poor flexibility and adaptability.

[0040] The film-coated rotating frame of the utility model takes 1 fixedly arranged first positioning assembly 31 as the position adjustment reference, sets other second positioning assemblies 32 to be able to move to any position on the circumference, and fastens them after determining the setting position, which can be adjusted according to products of different sizes to accommodate products of different sizes, quantities and film-coating demands, so that the clamping position of the hanger 4 can be flexibly changed according to the product demand to adapt to the loading of products of different sizes and make the loading capacity maximum. In this way, the demand for different rotating frames can be reduced to facilitate the adaptation of products of different sizes and the installation of different quantities of hangers 4 (rotating frame rods), realizing the flexible adaptation to products of different sizes, thereby reducing the manufacturing and labor costs, saving space and simplifying the operation process.

[0041] Figure 1 15 positioning assemblies 3 (including 1 first positioning assembly 31 and 14 second positioning assemblies 32,Figures 1-3 and Figures 5-7 The number of positioning assemblies 3 shown in each of the above-mentioned embodiments does not have a corresponding relationship, and the embodiments are only examples, but are not limited thereto. Figure 1 In the above-mentioned embodiments, one hanging rod 4 with a clamp 41 is also shown in a clamped state vertically clamped to one positioning assembly 3 (the first positioning assembly 31), and the clamp 41 is used for hanging the processing object.

[0042] Reference Figures 2-4 In some embodiments, the first guide rail 12 is circular and is placed on the top surface of the upper turntable 1. The center of the circular shape of the first guide rail 12 is located at the center of rotation of the frame.

[0043] In the above-mentioned embodiments, the first positioning part 33 of the first positioning assembly 31 is connected to the first support 5, and the first support 5 is fixed to the edge of the top surface of the upper turntable 1, so that the first positioning part 33 of the first positioning assembly 31 is fixed and supported on the edge of the top surface of the upper turntable 1 through the first support 5 and extends laterally out of the edge of the upper turntable 1.

[0044] In the above-mentioned embodiments, the first guide rail 12 can be provided with an avoiding gap when passing through the installation position of the first support 5, as shown in Figure 2 and Figure 3

[0045] Alternatively, the first guide rail can be disconnected when passing through the installation position of the first support. Further alternatively, when the inner edge of the first support is located outside the outer side of the first guide rail, the first guide rail can not need to be avoided when passing through the installation position of the first support.

[0046] In the above-mentioned embodiments, the first positioning part 33 of the second positioning assembly 32 is connected to the second support 7, and the second support 7 is movably arranged on the edge of the top surface of the upper turntable 1. Further, the second support 7 is abutted on the outer side of the circular shape of the first guide rail 12 through the inner side, and when the second support 7 is moved along the first guide rail 12, a sliding fit between the two is formed, so that the second support 7 has the function of a sliding block, so that the first positioning part 33 of the second positioning assembly 32 is also slidably fitted on the outer side of the circular shape of the first guide rail 12 through the second support 7 and is movably supported on the top surface of the upper turntable 1 through the second support 7 and extends laterally out of the edge of the upper turntable 1.

[0047] In the above-mentioned embodiments, the top surface of the upper turntable 1 is provided with a circular first pressing plate 6, and the center of the circular shape of the first pressing plate 6 is located at the center of rotation of the frame. The first pressing plate 6 is covered on the second support 7 from above and forms a clamping connection therebetween, which is used to limit the movement of the second support 7 and the first positioning part 33 of the second positioning assembly 32 connected thereto along the radial direction of the upper turntable 1.

[0048] ​And, the top surface of the first pressing plate 6 is provided with a ring groove 61 in the circumferential direction, and a first mounting hole 72 is provided on the top surface of the second support 7 in the circular outer side of the first guide rail 12 below the ring groove 61. At this time, the distance between any point on the ring groove 61 and the center of rotation of the frame body is consistent with the distance between the first mounting hole 72 and the center of rotation of the frame body. In this way, by passing the first fastener 62 through the ring groove 61 from above and screwing it into the first mounting hole 72, the second support 7 can be fastened to the top surface of the upper turntable 1, so that the first positioning part 33 of the second positioning assembly 32 can be fastened to the determined position of the top surface of the upper turntable 1 along the circumferential direction.

[0049] In some embodiments, the first fastener 62 includes a cap screw, and the first mounting hole 72 corresponds to a threaded hole.

[0050] The first pressing plate 6 can be mounted on the first guide rail 12.

[0051] The first pressing plate 6 can be disconnected at the mounting position of the first support 5 and fastened and mounted to the top surface of the upper turntable 1 through the disconnected end, as shown in Figure 2

[0052] Alternatively, the first pressing plate can be provided with an avoiding notch at the mounting position of the first support 5. Or, the first pressing plate can also cover the first support 5 at the mounting position of the first support 5.

[0053] The ring groove 61 is disconnected on both sides of the first support 5, but the circumferential length of the ring groove 61 should be adapted to the minimum distance between the first support 5 and the adjacent second support 7 on both sides.

[0054] In some embodiments, the top surface of the second support 7 is provided with a clamping block 71, as shown in Figure 3 The circular outer side of the first pressing plate 6 is provided with a downward protruding clamping buckle in the circumferential direction. When the first pressing plate 6 covers the second support 7, the clamping buckle is on the side away from the center of rotation of the frame body, i.e. on the outer side of the clamping block 71, and blocks the clamping block 71. Therefore, by clamping between the clamping buckle and the clamping block 71, the second support 7 is limited within the first pressing plate 6 and cannot be separated from the first pressing plate 6 and come out to the outer side of the upper turntable 1.

[0055] In some embodiments, the first positioning part 33 of the first positioning assembly 31 is vertically rotatable on the first support 5, and the first positioning part 33 of the second positioning assembly 32 is vertically rotatable on the second support 7. Taking the cooperation between the first positioning part 33 of the second positioning assembly 32 and the second support 7 as an example, as shown in Figure 4 ​As shown, the inner end of the first positioning part 33 of the second positioning assembly 32 can be rotationally connected with the second support 7 through a horizontal rotation axis, and further connected with the upper turntable 1 through the second support 7. In this way, the first positioning part 33 of the second positioning assembly 32 can rotate up and down around the rotation axis on the upper turntable 1, and can be rotated to the vertical state shown in Figure 4 (b) and the horizontal state shown in Figure 4 (a), and the upper end of the hanging rod 4 is pressed to clamp the upper and lower ends of the hanging rod 4 together with the first positioning part 33 of the second positioning assembly 32 on the lower turntable 2, and facilitate the loading and unloading of the hanging rod 4.

[0056] In some embodiments, the bottom surface of the outer end of the first positioning part 33 is provided with a first clamping part 331, which is used to press on the upper end of the hanging rod 4 to clamp when the first positioning part 33 is rotated to the horizontal state.

[0057] The center of the first clamping part 331 on the first positioning part 33 of each positioning assembly 3 is on the circumference of the same circle with the rotation center as the center.

[0058] In some embodiments, the first clamping part 331 includes a limit bearing built into the bottom surface of the outer end of the first positioning part 33, which is used to form a clamping fit by buckling into the upper end of the hanging rod 4 after the first positioning part 33 is flipped down.

[0059] Reference Figure 2 In some embodiments, the second guide rail 9 is circular and is placed flat on the top surface of the lower turntable 2. The center of the circular ring of the second guide rail 9 is located on the rotation center of the frame.

[0060] The second positioning part 34 of the first positioning assembly 31 is connected to the third support 10, which is supported on the edge of the top surface of the lower turntable 2 and extends to the top surface of the second guide rail 9 and is fixed to the top surface of the second guide rail 9, so that the second positioning part 34 of the first positioning assembly 31 is supported on the edge of the top surface of the lower turntable 2 through the third support 10 and is fixed to the top surface of the second guide rail 9, and extends laterally beyond the edge of the lower turntable 2.

[0061] The inner side of the second guide rail 9 can further extend inward at the installation position of the third support 10, that is, the annular width of the second guide rail 9 at this position is wider than other positions, to facilitate the installation of the third support 10, as shown in Figure 2 Of course, if the inner end of the third support is located between the inner diameter and the outer diameter of the second guide rail, the second guide rail does not have to be turned at the installation position of the third support.

[0062] The second positioning part 34 of the second positioning assembly 32 is connected to the fourth support 8, which is movably supported on the top edge of the lower turntable 2 and abuts against the outer side of the circular ring of the second guide rail 9. When the fourth support 8 is moved along the second guide rail 9, a sliding fit is formed therebetween, so that the fourth support 8 has the function of a sliding block. Thus, the second positioning part 34 of the second positioning assembly 32 is also supported on the top edge of the lower turntable 2 through the fourth support 8 and is slidably fitted on the outer side of the circular ring of the second guide rail 9 and laterally extends beyond the edge of the lower turntable 2.

[0063] In addition, the fourth support 8 also extends across the top surface of the second guide rail 9, and the bottom surface of the fourth support 8 is provided with a clamping groove 81, which is clamped on the outer side and the inner side of the circular ring of the second guide rail 9, for limiting the movement of the fourth support 8 in the radial direction of the lower turntable 2. The fourth support 8 is slidably fitted with the second guide rail 9 through the groove wall of the clamping groove 81, but preferably with the outer groove wall of the clamping groove 81 slidably fitted with the outer side of the circular ring of the second guide rail 9.

[0064] Meanwhile, a plurality of second mounting holes 91 are distributed on the top surface of the second guide rail 9 in the circumferential direction, and the top surface of the fourth support 8 is provided with an arc-shaped groove 82 (arc-shaped long groove). The distance between the arc-shaped groove 82 and the center of rotation of the frame body is equal to the distance between the second mounting hole 91 and the center of rotation of the frame body. In addition, the distribution density of the second mounting hole 91 satisfies that when the second positioning part 34 of the second positioning assembly 32 is determined at any one of the set positions in the circumferential direction of rotation, at least one second mounting hole 91 is exposed below the arc-shaped groove 82. In this way, by passing the second fastener from above through the arc-shaped groove 82 and screwing it into the second mounting hole 91, the fourth support 8 can be fastened on the top surface of the second guide rail 9, so that the second positioning part 34 of the second positioning assembly 32 is fastened on the determined set position of the top surface of the lower turntable 2 in the circumferential direction of rotation.

[0065] Therefore, by means of the slot-hole fitting mode, the fastening connection between the first positioning part 33 of the second positioning assembly 32 and the top surface of the upper turntable 1 at any set position in the circumferential direction and the fastening connection between the second positioning part 34 of the second positioning assembly 32 and the top surface of the lower turntable 2 at any set position in the circumferential direction are realized. By adopting the slot-hole fitting mode, the second positioning assembly 32 can be moved flexibly during assembly to adapt to different product quantities. When the product size changes to increase or decrease the quantity, the second positioning assemblies 32 on the turntable can be simply increased or decreased, and they can be slid to the appropriate angle, so that the carrying capacity and stability can be expanded. The position of each second positioning assembly 32 can be freely adjusted, and after being fixed, stable support can be provided. Thus, the need for frequent replacement of the turntable is avoided.

[0066] In some embodiments, the top surface of the second guide rail 9 is provided with two circles of second mounting holes 91 distributed circumferentially, and the top surface of the fourth support 8 is correspondingly provided with two arc-shaped grooves 82 to enhance the fastening effect.

[0067] In some embodiments, the second fastener comprises a screw with a cap, and the second mounting hole 91 is correspondingly a threaded hole.

[0068] In some embodiments, the top surface of the lower turntable 2 is provided with a circular ring-shaped second pressing plate 11, and the center of the circular ring of the second pressing plate 11 is located at the rotation center of the frame body. Moreover, the second pressing plate 11 covers the fourth support 8 to limit the upward bending of the inner side end of the fourth support 8 near the rotation center of the frame body when the outer side end is pressed more.

[0069] Further, the second pressing plate 11 is disconnected on both sides of the third support 10, but the ring length of the second pressing plate 11 should be adapted to the minimum setting distance between the third support 10 and the adjacent fourth support 8 on both sides, so as to be able to press all the fourth supports 8. Of course, the ring of the second pressing plate can be closed without disconnection, and can be pressed on the third support 10.

[0070] The second pressing plate 11 can be fastened to the top surface of the lower turntable 2 exposed inside the inner diameter of the second guide rail 9.

[0071] Reference Figure 1 , Figures 5-7 In some embodiments, the top surface area of the lower turntable 2 and the outer side are also provided with a baffle, which is used to shield the lower turntable 2 from above and the outside, but needs to expose the second clamping part 341 provided on the top surface of the second positioning part 34. The second clamping part 341 is used to support the lower end of the hanging rod 4 to clamp the upper and lower ends of the hanging rod 4 together with the first clamping part 331. The center of the second clamping part 341 on the second positioning part 34 of each positioning assembly 3 is on the same circle with the rotation center as the center.

[0072] Reference Figure 2 In some embodiments, the second positioning part 34 comprises a supporting bearing 342 and a hollow pin shaft vertically arranged on the supporting bearing 342. The hollow pin shaft serves as the second clamping part 341. The supporting bearing 342 of the second positioning part 34 of the first positioning assembly 31 is installed on the third support 10, and the supporting bearing 342 of the second positioning part 34 of the second positioning assembly 32 is installed on the fourth support 8.

[0073] The hollow pin shaft can be, for example Figure 2One of the shown top end is provided with a support hole, the side with a U-shaped slot pin shaft. When installing the hanging rod 4, the lower end of the hanging rod 4 is matched in the support hole of the pin shaft, and a limit pin is horizontally arranged on the lower end of the hanging rod 4, which falls into the U-shaped slot, which can limit the rotation of the hanging rod 4 relative to the support bearing 342.

[0074] In some embodiments, the baffle includes a first baffle 13, a second baffle 14, a third baffle 15 and a fourth baffle 16.

[0075] Wherein the number of first baffles 13 is consistent with the number of second positioning parts 34, and the first baffles 13 are covered on the second positioning parts 34, as shown.
