Description

Technical Field

[0001] The utility model relates to the technical field of processing and feeding, in particular to a turnover and lifting mechanism. Background Art

[0002] Loading refers to sending the workpiece to the working position. In actual use, the workpiece to be processed is usually placed on a transmission mechanism (such as a conveyor belt), and the workpiece to be processed is transmitted through the transmission mechanism so that the workpiece is transmitted to the processing position.

[0003] Currently, the loading efficiency is low. Usually, one workpiece or a batch of workpieces is placed on the transmission mechanism. After the batch or workpiece is transported away, the next workpiece or the next batch of workpieces is manually placed on the transmission mechanism. In this way, a worker is required to load the workpiece onto the transmission mechanism at the loading position, which is time-consuming and requires a fixed worker to wait at the loading position. When the previous and subsequent workpieces are not continuous, it is easy to have a shortage of materials. Utility Model Content

[0029] Embodiment 1:

[0030] See also Figure 1-5 , the utility model provides a technical solution: a flip lifting mechanism, including: a silo 1 for storing a tray 3, a telescopic pushing mechanism located at the lower side of the silo 1, a moving plate 12 located in a protective cover 23, a flip pushing cylinder 13, and a swing rod 17;

[0031] The silo 1 is hollow and open on the right side, the upper end of the telescopic pushing mechanism is connected to a lifting push rod 10, the lower surface of the silo 1 is provided with a sliding hole corresponding to the position of the lifting push rod 10, the left side wall of the silo 1 is provided with a protective cover 23, the flip pushing cylinder 13 is installed on the left side wall of the silo 1, the telescopic end of the flip pushing cylinder 13 is connected to the support rod 14, the movable plate 12 is installed on the upper side of the support rod 14, and the left and right sides of the outer wall of the movable plate 12 are provided with movable connecting seats 15, and a swing driving block 16 is inserted into the movable connecting seat 15. The left and right outer walls of the silo 1 are rotatably connected with a swing rod 17, and the outer walls of the swing rod 17 are fixedly connected with a flip supporting arm 18 on both sides, and the left and right sides of the silo 1 are provided with a strip groove 19 corresponding to the flip supporting arm 18, and the end of the swing driving block 16 away from the movable connecting seat 15 is fixedly connected to one end of the swing rod 17.

[0032] Analysis of the above content: When in use, the pallet 3 carrying the workpiece is installed between the two slide rails 2 in the silo 1 through the slider 4, and is stacked longitudinally in sequence.

[0033] The silo 1 is set up on the upper side of one end of the processing and loading conveyor belt, and the jacking push rod 10 is located at the periphery of the processing and loading conveyor belt. When loading is required, the telescopic pushing mechanism pushes the jacking push rod 10 upward, and the jacking push rod 10 is pushed up from the periphery of the processing and loading conveyor belt and pushes all the pallets 3 upward (the pallet width is greater than the width of the processing and loading conveyor belt, which does not affect the normal transmission of the processing and loading conveyor belt) until the second pallet 3 from the bottom to the top reaches the flip support arm 18, the telescopic pushing mechanism stops working and drives the flip support arm 18 to support the second pallet 3 from the bottom to the top and the pallets 3 above. At this time, the telescopic end of the telescopic pushing mechanism drives the jacking push rod 10 to descend, and the lowermost pallet 3 is lowered, so that the lowermost pallet 3 can be separated from the upper pallet 3.

[0034] The transfer plate 21 moves to the lower side of the silo 1 under the transmission of the processing and loading conveyor belt, and the lowermost tray 3 descends onto the transfer plate 21 (the four corners of the transfer plate 21 are concave and will not contact the lifting push rod 10), and the positioning column 22 is plugged into the slider 4 on the lowermost tray 3. The slide rail 2 and the positioning column 22 are set to be cylindrical with the same specifications, so that the positioning column 22 and the slider 4 can be well matched, and the processing and loading conveyor belt can remove the transfer plate 21 and the tray 3 thereon. After that, the telescopic push mechanism pushes the lifting push rod 10 to rise, and the lifting push rod 10 is again supported on the tray 3 supported by the flip support arm 18, and then the flip support arm 18 rotates and resets, and the lifting push rod 10 descends to drive all trays 3 to descend, and the next loading is carried out. Under the transmission of the processing and loading conveyor belt, the transfer plate 21 moves back and forth between the silo 1 and the transmission destination.

[0037] Analysis of the above content: Through the cooperation between the slider 4 and the slide rail 2, the trays 3 are stacked longitudinally in sequence and keep a stable position, which is convenient for continuous loading and is not prone to jamming.

[0038] Embodiment three:

[0039] See also Figure 1-5 The utility model provides a technical solution based on the first embodiment: the telescopic pushing mechanism includes a lower bearing plate 6, the upper surface of the lower bearing plate 6 is connected to the lower surface of the silo 1 through the legs 7, the lower surface of the lower bearing plate 6 is provided with a longitudinal pushing mechanism, the upper surface of the lower bearing plate 6 is provided with a movable plate 8, the bottom end of the jacking push rod 10 is installed on the upper surface of the movable plate 8, and the longitudinal pushing mechanism is connected to the movable plate 8. The longitudinal pushing mechanism includes a reduction drive motor 5 installed on the lower surface of the lower bearing plate 6 and a lead screw 9 installed on the output shaft of the reduction drive motor 5, the lead screw 9 penetrates the lower bearing plate 6 and extends upward, and the middle part of the lead screw 9 is connected by threaded matching.

[0040] Analysis of the above content: When in use, the reduction drive motor 5 drives the lead screw 9 to rotate forward or reversely, and the lead screw 9 drives the movable plate 8 to move longitudinally through threaded engagement, and the longitudinal movement of the movable plate 8 drives the lifting push rod 10 to move longitudinally. A linear bearing can be installed at the connection between the lifting push rod 10 and the silo 1 to reduce friction.

[0041] Embodiment 4:

[0042] See also Figure 1-5 The utility model provides a technical solution based on the first embodiment: a guide slider is arranged on the side of the movable plate 12 facing the silo 1, and a guide rail 11 matched with the guide slider is arranged on the left side wall of the silo 1.

[0043] Analyzing the above contents: the cooperation between the guide slider and the guide rail 11 enables the moving plate 12 to move more smoothly on the outer wall of the silo 1 .

[0044] Embodiment five:

[0045] See also Figure 1-5 The utility model provides a technical solution based on the first embodiment: the end of the flip support arm 18 away from the swing rod 17 is rotatably connected to the support wheel 20.

[0046] Analysis of the above content: The setting of the support wheel 20, when the flip support arm 18 flips and there is a situation where the flip support arm 18 contacts the tray 3, the setting of the support wheel 20 makes the contact between the flip support arm 18 and the tray 3 rolling friction, thereby reducing wear.

[0049] Analysis of the above content: When in use, the telescopic end of the flip push cylinder 13 drives the moving plate 12 to move up and down, and the up and down movement of the moving plate 12 drives the end of the swing drive block 16 to swing up and down through the movable connection seat 15. The swing of the swing drive block 16 drives the swing rod 17 and the flip support arm 18 to swing, so that the flip support arm 18 swings up and down inside the strip groove 19. When the flip support arm 18 rotates from the inside of the silo 1 to the strip groove 19, it will not affect the up and down movement of the tray 3. When the flip support arm 18 rotates from the inside of the strip groove 19 to the silo 1, the flip support arm 18 protruding into the silo 1 can support the upper tray 3 to prevent the tray 3 from falling.
