It is understood that the specific embodiments described herein are only used to explain the utility model, rather than to limit the utility model. It is also necessary to explain that, for the convenience of description, only the parts related to the utility model are shown in the accompanying drawings, rather than all the mechanisms.

[0027] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "rotation transmission assembly" and "lifting transmission assembly" are only used to distinguish in the description and have no special meaning.

[0028] refer to Figure 1-Figure 6 As shown, an automatic lifting and rotating mechanism is proposed in the embodiment of the utility model, including a lifting platform 2, a support platform 1, a turntable 3, a driving member 9, a first transmission assembly 5 and a second transmission assembly 6, wherein the support platform 1 is used as an installation base, and the lifting platform 2 is arranged above the support platform 1 and is connected to the support platform 1 along a first direction ( Figure 1 The turntable 3 is rotatably connected to the lifting platform 2 through the rotating shaft 4. The turntable 3 is used to hold materials or to install a storage platform for holding materials. Its specific structure is adaptively adjusted according to the different functions of holding materials or installing a storage platform, and will not be described in detail here. The driving member 9 is set on the support platform 1 to provide power. The first transmission component 5 connects the driving member 9 and the lifting platform 2, and can convert the power provided by the driving member 9 into the power for the lifting platform 2 to rise and fall in the first direction. The second transmission component 6 connects the driving member 9 and the turntable 3, and can convert the power provided by the driving member 9 into the power for the turntable 3 to rotate.

[0029] When the material on the transport line is reversed by manual reversing, at least two actions are included, one of which is to make the material leave the transport line, and the other is to rotate the material. In the above-mentioned automatic lifting and rotating mechanism, the driving member 9 drives the lifting platform 2 to achieve the purpose of making the material leave the transport line or return to the transport line, and at the same time, the driving member 9 drives the turntable 3 to rotate to achieve the purpose of rotating the material, thereby realizing automatic reversal with high reversing accuracy. Moreover, in the above-mentioned automatic lifting and rotating mechanism, the same driving member 9 can be used to simultaneously realize the rotation reversing action and the lifting action of leaving or returning to the transport line, and the reversing cost is low.

[0030] In this embodiment, the driving member 9 adopts a linear driving member such as a cylinder, an oil cylinder, a linear motor, etc. The linear driving member is easier to control the stroke than the rotary driving member. The linear driving member is preferably a cylinder, which is cheaper than a linear motor and less likely to leak and pollute than an oil cylinder.

[0031] Based on the linear drive element selected as the drive element 9, refer to Figure 2-Figure 4 As shown, the first transmission assembly 5 includes a reversing member 51 and a resisting member 52, one of which is connected to the driving member 9 to move in the second direction ( Figure 1 The second direction is perpendicular to the first direction.

[0032] Taking the example that the driving member 9 is connected to the reversing member 51 and the push member 52 is arranged on the lifting platform 2, the reversing member 51 moves along the guide surface under the action of the driving member 9, the contact position between the push member 52 and the guide surface changes, and the height of the push member 52 along the first direction naturally changes. Driven by the push member 52, the lifting platform 2 rises and falls along the first direction.

[0033] In this embodiment, the reversing member 51 is a wedge block, which is inclined on one side facing the lifting platform 2 to form a guide surface, and the supporting member 52 is a pulley, which is rotatably arranged on the lower surface of the lifting platform 2 through a pulley seat and is in rolling contact with the wedge block.

[0034] In other embodiments, both the switching member 51 and the abutting member 52 may be wedge-shaped blocks, and the inclined angles of the inclined surfaces arranged on the switching member 51 and the abutting member 52 are the same.

[0035] Alternatively, the reversing member 51 can adopt a guide seat with a guide groove, the guide groove is opened on the side of the guide seat extending along the second direction and is inclined along the first direction, the groove wall of the guide groove serves as a guide surface, and the push-up member 52 can be a sliding rod with one end inserted into the guide groove and slidingly matched with the reversing member 51.

[0036] refer to Figure 2-Figure 6 As shown, the second transmission assembly 6 includes a transmission rod 61 and a guide block 62, wherein the transmission rod 61 is eccentrically connected to the rotating shaft 4 through a first connecting rod 63 and extends along a first direction, and the guide block 62 is connected to the driving member 9, and a guide block 62 is provided along a third direction ( Figure 1 The transmission rod 61 is inserted into the guide hole 62a and can slide in the guide hole 62a along the extending direction of the guide hole 62a. The second direction, the first direction and the third direction are perpendicular to each other.

[0037] When the guide block 62 moves along the second direction under the action of the driving member 9, the transmission rod 61 located in the guide hole 62a moves along the second direction with the guide block 62, thereby driving the rotating shaft 4 connected to the transmission rod 61 to rotate, thereby realizing the rotation of the turntable 3.

[0038] It should be noted that when the driving member 9 moves along the second direction, under the action of the first transmission assembly 5, the height of the lifting platform 2 relative to the support platform 1 in the first direction changes. Therefore, the transmission rod 61 connected to the rotating shaft 4 and inserted into the guide hole 62a is slidably connected to the rotating shaft 4 in the first direction, or the transmission rod 61 can be slidably connected to the guide block 62 along the first direction while sliding along the extension direction of the guide hole 62a.

[0039] Taking the example of the transmission rod 61 and the guide block 62 being slidably connected in the first direction, the transmission rod 61 is limited to the rotating shaft 4 in the first direction, that is, the transmission rod 61 can be raised and lowered synchronously with the turntable 3 arranged on the lifting platform 2. In order to reduce the friction between the transmission rod 61 and the guide block 62, a roller 65 is sleeved on the transmission rod 61, and the roller 65 is rollingly arranged in the guide hole 62a and can move in the first direction relative to the transmission rod 61. Specifically, the transmission rod 61 is rotatably connected to the first connecting rod 63, and the roller 65 is circumferentially limited to the transmission rod 61. When the roller 65 rolls in the guide hole 62a, the transmission rod 61 rotates together with the roller 65.

[0040] In order to prevent the roller 65 from being separated from the guide hole 62a when the transmission rod 61 is lifted or lowered along the first direction, the guide hole 62a includes a guide section for accommodating the roller 65 and avoidance sections arranged at both ends of the guide section along the first direction, and the width of the avoidance section along the second direction is smaller than the width of the roller 65. Specifically, the guide block 62 includes a slot seat 621 and a cover plate 622 which are separately arranged, the guide section and one of the avoidance sections are arranged on the slot seat 621, and the other avoidance section is arranged on the cover plate 622, and the cover plate 622 is fixedly connected to the guide block 62 to form the guide hole 62a. The slot seat 621 and the cover plate 622 which are separately arranged reduce the difficulty of processing the guide hole 62a.

[0041] Taking space utilization into consideration, in some embodiments, the driving member 9 and the reversing member 51 are respectively located on opposite sides of the guide block 62 along the second direction, the driving member 9 is directly connected to the guide block 62, and the guide block 62 is connected to the reversing member 51 through a second connecting rod 64 extending along the second direction, thereby realizing the connection between the reversing member 51 and the driving member 9.

[0042] In other embodiments, the second transmission assembly 6 can also adopt a transmission rod 61 and an articulated connecting rod. The transmission rod 61 is eccentrically connected to the rotating shaft 4 through the first connecting rod 63 and extends along the first direction. One end of the articulated connecting rod is hinged to the driving member 9, and the other end is rotatably connected to the transmission rod 61, and the transmission rod 61 can move along the first direction relative to the articulated connecting rod.

[0043] refer to Figure 2 As shown, in this embodiment, the automatic lifting and rotating mechanism also includes a first guide assembly 7, which includes a slide rail 71 extending along the second direction and arranged on the support platform 1, and a slider 72 slidably matched with the slide rail 71, and the slider 72 is fixed at the bottom of the reversing member 51. In addition, both sides of the slide rail 71 along the second direction are provided with limit blocks 73, and the reversing member 51 can abut against the limit blocks 73 to achieve travel limit. The setting of the slide rail 71 and the slider 72 can make the reversing member 51 move stably along the second direction, and the setting of the limit block 73 can accurately limit the rotation angle of the turntable 3, further improving the material reversing accuracy.

[0044] It is understandable that the rotation angle of the turntable 3 is limited according to actual needs, and the rotation angle of the turntable 3 depends on the vertical distance between the transmission rod 61 and the rotating shaft 4 and the distance moved along the second direction by the driving member 9. It should be noted that in order to make the rotation angle of the turntable 3 exceed 90°, the length of the guide hole 62a along the third direction is not less than the vertical distance between the transmission rod 61 and the rotating shaft 4.

[0045] Further, in order to improve the horizontality of the lifting platform 2 and the rotation accuracy of the turntable 3, two groups of the first transmission assembly 5 and the second transmission assembly 6 are provided and arranged in opposite directions, and two driving members 9 are also provided, which are respectively vertically connected to the guide blocks 62 in the two second transmission assemblies 6. Specifically, the guide blocks 62 in the two second transmission assemblies 6 have different heights in the first direction, and the guide rods in the two second transmission assemblies 6 are connected by the same first connecting rod 63.

[0046] In this embodiment, the automatic lifting reversing mechanism further includes a second guide assembly 8, including a sliding sleeve 82 and a sliding shaft 81, one of the sliding sleeve 82 and the sliding shaft 81 is arranged on the lifting platform 2 along the first direction, and the other is arranged on the supporting platform 1 along the first direction, and the sliding shaft 81 can be inserted into the sliding sleeve 82 and slide with the sliding sleeve 82, and the lifting and supporting platform 1 are slidably connected along the first direction through the sliding sleeve 82 and the sliding shaft 81. Specifically, the second guide assembly 8 is provided with four groups, and the four sliding shafts 81 are respectively arranged at the four corners of the rectangular supporting platform 1, and the four sliding sleeves 82 are correspondingly arranged at the four corners of the rectangular lifting platform 2.

[0047] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
