Detailed implementation manners

[0037] For the purpose of making the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0038] Refer to the attached Figures 1 to 3 As shown in the figure, this embodiment provides an abalone production line connection device with different heights, including a frame 1, a first non-powered conveying roller 2, a second non-powered conveying roller 3, a lifting baffle mechanism 4, a linkage mechanism 5, a lifting drive device 6 and a lifting adjustment mechanism 7. The top of the frame 1 is respectively provided with the first non-powered conveying roller 2 and the second non-powered conveying roller 3. The first non-powered conveying roller 2 is fixedly connected to the frame 1, and the middle part of the second non-powered conveying roller 3 is hinged to the frame 1.

[0039] Among them, the frame 1 includes a channel steel base 101, a telescopic sleeve 102, a connecting column 103, a mounting plate 104 and a channel steel platform 105. Telescopic sleeves 102 are arranged at the four corners of the top of the channel steel base 101. Specifically, the telescopic sleeve 102 is composed of two pipe fittings sleeved together and can be telescoped along its axial direction. The two telescopic sleeves 102 on the same side are connected and fixed by the connecting column 103. The mounting plate 104 is fixed between the two side connecting columns 103. A channel steel platform 105 is fixed at the top of the telescopic sleeve 102. The first non-powered conveying roller 2 is fixedly connected to the channel steel platform 105, and the middle part of the second non-powered conveying roller 3 is hinged to the channel steel platform 105.

[0040] Specifically, in this embodiment, the first non-powered conveying roller 2 and the second non-powered conveying roller 3 have the same structure and are both composed of a roller row channel steel 21 and a non-powered roller 22. The two ends of the non-powered roller 22 are respectively rotatably connected to the two side roller row channel steels 21 (as shown in the attached Figure 4 figure).

[0041] Refer to the attached Figure 5As shown, a first connecting plate 15 is provided at the bottom of the second unpowered conveying roller 3. The first connecting plate 15 is located in the middle of the bottom surface of the second unpowered conveying roller 3, and its two ends are respectively fixed on the roller row channel steels 21 on both sides of the second unpowered conveying roller 3. The first connecting plate 15 is connected to the channel steel table 105 through a movable hinge 10, so that the outer side of the second unpowered conveying roller 3 can be turned downward and inclined. Second connecting plates 16 and third connecting plates 17 are respectively provided on both sides of the first connecting plate 15. The second connecting plate 16 is located on the side of the bottom of the second unpowered conveying roller 3 close to the first unpowered conveying roller 2, and the third connecting plate 17 is located on the side of the bottom of the second unpowered conveying roller 3 far from the first unpowered conveying roller 2. Both ends of the second connecting plate 16 and the third connecting plate 17 are respectively fixed on the roller row channel steels 21 on both sides of the second unpowered conveying roller 3.

[0042] Refer to the appendix Figure 2 and 6 As shown, the lifting drive device 6 is installed in the middle of the frame 1 and is used to drive the outer side of the second unpowered conveying roller 3 to turn downward and incline. In this embodiment, the top of the telescopic end of the lifting drive device 6 is hinged to the second connecting plate 16 through a first hinge seat 8, and both ends of the lifting drive device 6 are rotatably connected to the top of the mounting plate 104 through a rotating base 9. Among them, the rotating base 9 includes a support piece 91, a vertical bearing seat 92 and a support pipe 93. Support pieces 91 are fixedly connected to both sides of the lifting drive device 6, and the side parts of the support pieces 91 are rotatably connected to the support pipe 93 through the vertical bearing seat 92, and the support pipe 93 is fixedly connected to the top of the mounting plate 104. The lifting drive device 6 can be an electric screw jack or a gear rack electric jack. In this embodiment, the lifting drive device 6 is a gear rack electric jack.

[0043] When the lifting drive device 6 extends, it will push the side of the second unpowered conveying roller 3 close to the first unpowered conveying roller 2 to lift upward through the first hinge seat 8. At this time, the outer side of the second unpowered conveying roller 3 turns downward and inclines, and the goods on the second unpowered conveying roller 3 slide downward along the second unpowered conveying roller 3 under the action of gravity and move to the conveyor line with a lower height, so as to realize the transfer of the turnover box from the horizontal operating table with a higher horizontal height to the input end of the sloping conveyor line with a height difference (lower horizontal height).

[0044] Refer to the appendix Figure 1 and 7 As shown, the lifting baffle mechanism 4 is fixedly installed on the frame 1, and the baffle 43 at its upper end is located between the first unpowered conveying roller 2 and the second unpowered conveying roller 3 and is used to block the goods on the first unpowered conveying roller 2 from being conveyed towards the second unpowered conveying roller 3.

[0045] In this embodiment, the lifting baffle mechanism 4 includes a bottom plate 41, a horizontal fixed pipe 42, a baffle 43, a smooth shaft 44, a spring 45, a roller mounting plate 46 and rollers 47. A smooth shaft 44 is fixedly connected to the top of the bottom plate 41. The upper end of the smooth shaft 44 passes through a circular hole reserved on the horizontal fixed pipe 42 and is fixedly connected to the baffle 43. Both ends of the horizontal fixed pipe 42 are fixedly connected to the bottom of the channel steel platform 105 through hanging fixing members 14. Specifically, hanging fixing members 14 are fixedly connected to both ends of the horizontal fixed pipe 42, and the upper ends of the hanging fixing members 14 are fixedly connected to the bottom of the channel steel platform 105. The upper and lower ends of the spring 45 are respectively fixedly connected to the baffle 43 and the horizontal fixed pipe 42, and the spring 45 is sleeved on the smooth shaft 44. Two roller mounting plates 46 are also fixedly arranged on the top of the bottom plate 41. Two rollers 47 are rotatably connected between the two roller mounting plates 46. The two rollers 47 are longitudinally arranged at intervals. The end of the linkage mechanism 5 passes between the two rollers 47.

[0046] During operation, the linkage mechanism 5 can push the bottom plate 41 to move upward through the rollers 47 on the roller mounting plate 46. When the bottom plate 41 moves upward, it pushes the baffle 43 to lift upward through the smooth shaft 44 while the spring 45 is stretched. The baffle 43 lifts out between the first unpowered conveyor roller 2 and the second unpowered conveyor roller 3 to block the goods on the first unpowered conveyor roller 2 from being conveyed towards the second unpowered conveyor roller 3. Driven in the reverse direction by the linkage mechanism 5, the baffle 43 can be lowered to reset, and at the same time, the elastic force released by the spring 45 can also assist in pulling the baffle 43 to lower and reset.

[0047] When the second unpowered conveyor roller 3 conveys goods obliquely, if the goods on the first unpowered conveyor roller 2 continue to move towards the second unpowered conveyor roller 3 at this time, it is easy to cause the second unpowered conveyor roller 3 to get stuck and unable to flip back to the horizontal state. Therefore, when the second unpowered conveyor roller 3 conveys goods obliquely, the pushing baffle 43 on the lifting baffle mechanism 4 will lift upward to block the goods on the first unpowered conveyor roller 2 from being conveyed towards the second unpowered conveyor roller 3. When the second unpowered conveyor roller 3 returns to the horizontal state, the pushing baffle 43 will lower and reset under the unpowered roller 22 to avoid blocking the goods on the unpowered conveyor roller.

[0048] Refer to the appendix Figure 2 And 8As shown, the linkage mechanism 5 is installed on the frame 1 and is respectively connected and cooperated with the second non-powered conveying roller 3 and the lifting baffle mechanism 4. The linkage mechanism 5 drives the baffle 43 on the lifting baffle mechanism 4 to lift and lower through the pushing and pulling forces provided when the second non-powered conveying roller 3 flips. In this embodiment, the linkage mechanism 5 includes a lever fulcrum base 51, a hinge frame 52, a cross bar 53, a longitudinal bar 54 and a second hinge seat 55. The lever fulcrum base 51 is fixed on the mounting plate 104. The top of the lever fulcrum base 51 is fixed with a hinge frame 52. The middle of the cross bar 53 is hinged to the hinge frame 52. One end of the cross bar 53 is hinged to the longitudinal bar 54. The other end of the cross bar 53 passes between the two rollers 47, and there is a clearance fit between the cross bar 53 and the two rollers 47. The end of the longitudinal bar 54 is hinged to the third connecting plate 17 through the second hinge seat 55.

[0049] When the lifting drive device 6 pushes the second non-powered conveying roller 3 to flip, the outer side of the second non-powered conveying roller 3 inclines downward and presses down the longitudinal bar 54 through the third connecting plate 17. When the longitudinal bar 54 is pressed down, the end of the cross bar 53 passing between the two rollers 47 is lifted. The lifted end of the cross bar 53 pushes the bottom plate 41 to move upward through the roller 47 on the roller mounting plate 46. The upward movement of the bottom plate 41 pushes the baffle 43 to be jacked up and at the same time the spring 45 is stretched. The baffle 43 is jacked up and passes out between the first non-powered conveying roller 2 and the second non-powered conveying roller 3, blocking the goods on the first non-powered conveying roller 2 from continuing to be conveyed in the direction of the second non-powered conveying roller 3. When the lifting drive device 6 contracts and drives the second non-powered conveying roller 3 to flip to the horizontal position, the second non-powered conveying roller 3 pulls up the longitudinal bar 54 through the third connecting plate 17. The end of the cross bar 53 passing between the two rollers 47 presses down to make the bottom plate 41 descend and reset. The baffle 43 descends and resets under the drive of the elastic force of the bottom plate 41 and the spring 45. The baffle 43 descends and resets below the non-powered roller 22, avoiding blocking the goods on the non-powered conveying roller.

[0050] Refer to the appendix Figure 2 and 3 As shown, the lifting adjustment mechanism 7 is installed on the frame 1 and is used to adjust the height of the frame 1. Multiple groups of the lifting adjustment mechanism 7 can also be set to further ensure the stability of the device.

[0051] In this embodiment, the lifting and adjusting mechanism 7 includes a threaded rod 71, an upper handwheel 72 and a lower handwheel 73. The lower end of the threaded rod 71 is fixed on the channel steel base 101, and the upper end of the threaded rod 71 passes through the avoidance round hole reserved on the mounting plate 104. The upper handwheel 72 and the lower handwheel 73 are respectively located on the upper and lower sides of the mounting plate 104. Both the upper handwheel 72 and the lower handwheel 73 are threadedly connected to the threaded rod 71 and clamp the mounting plate 104. When it is necessary to adjust the height of the frame 1, first loosen the upper handwheel 72, and then adjust the height of the frame 1 by rotating the lower handwheel 73. After adjusting the height of the frame 1, tighten the upper handwheel 72 so that the upper and lower handwheels clamp the mounting plate 104 to fix the height of the frame 1. By setting the lifting and adjusting mechanism 7, the height of the unpowered conveying roller can be adjusted to adapt to conveying lines of different heights.

[0052] Refer to Attachment Figure 2 , 3 As shown in FIGS. 9, a diffuse reflection sensor 13 is provided below the second unpowered conveying roller 3. The diffuse reflection sensor 13 is fixedly installed on the channel steel platform 105 through a connecting piece and is used to detect whether there is goods on the top of the second unpowered conveying roller 3. When the diffuse reflection sensor 13 detects the in-place signal of the turnover box on the top of the second unpowered conveying roller 3, the lifting drive device 6 is triggered to start, driving the second unpowered conveying roller 3 to flip.

[0053] A second proximity switch 12 is installed on the mounting plate 104. When the second unpowered conveying roller 3 is in a horizontal state, the second proximity switch 12 is directly opposite to the bottom end of the telescopic rod on the lifting drive device 6.

[0054] A first proximity switch 11 is provided on the side of the lifting drive device 6. The first proximity switch 11 is fixedly connected to the lifting drive device 6 through a connecting piece, and the first proximity switch 11 is directly opposite to the side of the lower telescopic rod of the lifting drive device 6. Specifically, a fixing plate (the fixing plate is installed on the lifting drive device 6) is fixedly installed on the side of the lifting drive device 6. A strip-shaped groove is longitudinally opened on the fixing plate. The first proximity switch 11 passes through the strip-shaped groove and is directly opposite to the side of the lower telescopic rod of the lifting drive device 6. Two nuts are threadedly connected to the first proximity switch 11, and the two nuts are respectively located on both sides of the fixing plate and clamp the fixing plate to fix the position of the first proximity switch 11. The position of the first proximity switch 11 can be adjusted in this way; when the lifting drive device 6 rotates, the first proximity switch 11 will rotate with the lifting drive device 6.

[0055] The first proximity switch 11 and the second proximity switch 12 are used to define the lifting stroke of the lifting drive device 6. The first proximity switch 11 is facing the side of the lower telescopic rod of the lifting drive device 6. When the telescopic end of the lifting drive device 6 rises, the first proximity switch 11 detects the signal of the lower telescopic rod. When the first proximity switch 11 does not detect the telescopic rod, it means that the lifting drive device 6 has risen in place.

[0056] During the rising process of the telescopic end of the lifting drive device 6, it will flip on the rotating base 9. When the telescopic end of the lifting drive device 6 descends, the lifting drive device 6 will gradually rotate and reset. When the second proximity switch 12 detects that the bottom end of the upper telescopic rod on the lifting drive device 6 is in place, it is considered that the lifting drive device 6 has completed the contraction and reset.

[0057] When the connecting device provided by the present invention is in use, first, adjust the upper handwheel 72 and the lower handwheel 73 to make the non-powered conveying roller flush with the conveying line with a higher horizontal height.

[0058] Then start the device. When the diffuse reflection sensor 13 detects that the turnover box on the second non-powered conveying roller 3 is in place, the lifting drive device 6 drives the second non-powered conveying roller 3 to flip and tilt, so that the turnover box slides onto the conveying line with a lower horizontal height; at the same time, during the flipping process of the second non-powered conveying roller 3, under the action of the linkage mechanism 5, the baffle on the lifting baffle mechanism 4 is ejected from between the first non-powered conveying roller 2 and the second non-powered conveying roller 3 to block the further conveying of the materials on the first non-powered conveying roller 2 to the second non-powered conveying roller 3, and prevent the second non-powered conveying roller 3 from being stuck by the turnover box and unable to flip and reset.

[0059] After the diffuse reflection sensor 13 detects that there is no turnover box on the second non-powered conveying roller 3, the lifting drive device 6 drives the second non-powered conveying roller 3 to rotate and reset to make it return to the horizontal; during the rotation process of the second non-powered conveying roller 3, under the action of the linkage mechanism 5, the baffle on the lifting baffle mechanism 4 descends below the non-powered roller 22, so that the turnover box on the first non-powered conveying roller 2 can be normally conveyed to the second non-powered conveying roller 3. In this way, the turnover box is cyclically conveyed from the horizontal operating platform with a higher horizontal height to the input end of the sloping production line with a height difference (lower horizontal height). During the lifting process driven by the lifting drive device 6, the first proximity switch 11 and the second proximity switch 12 are used to define the lifting stroke of the lifting drive device 6.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
