Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, and in particular to a rotary material rack lifter. Background Technology

[0002] A rack lifter is a specialized device used to vertically lift a rack to a target height. Its core function is to drive the rack to lift it smoothly through a power component. It is widely used in material handling, production lines and other scenarios.

[0003] A right-angle turning conveyor belt for flower baskets, Chinese Patent No. CN221478678U, includes a main body and a turning part. The turning part has a cylinder lifting mechanism and is fixed to the main body via a turning connecting plate. Through-beam sensor assemblies are installed at the discharge ports on both sides of the aluminum profile. The advantages of this invention are: the silicon wafers in the flower basket can be directly reversed on the conveyor line, greatly reducing the space required for the equipment; the design structure is simple, the manufacturing cost is low, and the operation is convenient, effectively avoiding the problem of silicon wafer breakage in the flower basket.

[0004] In actual lifting operations, due to the possible differences in the weight distribution of the material rack to be processed, and the slight synchronous fluctuations that may occur during the lifting power output process, the material rack is very likely to break through the constraints of the simple limit structure during vertical lifting, resulting in lateral displacement, which makes it impossible for the material to be processed to stop accurately and stably at the target position. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rotary material rack lifter, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a rotary material rack lifter, including a material conveying outer frame, an inner bottom plate fixedly connected to the lower inner wall of the material conveying outer frame, electric push rods symmetrically fixedly connected to the upper left and right sides of the inner bottom plate, a horizontal top plate installed at the output end of the two electric push rods, a motor fixedly connected to the upper middle part of the horizontal top plate, a linkage vertical rod installed at the output end of the motor, a cross lifting reversing frame fixedly connected to the upper end of the linkage vertical rod, multiple rectangular grooves opened at the upper end of the cross lifting reversing frame, the multiple rectangular grooves being equidistantly arranged, a telescopic inner rod fixedly connected to the lower inner wall of the rectangular groove, a vertical spring sleeved on the outer end of the telescopic inner rod, and an inner vertical slider fixedly connected to the upper end of the telescopic inner rod.

[0007] As a further technical solution of this utility model, the two sides of the cross-lifting reversing frame are symmetrically fixedly connected with reinforcing side ribs, and the inner vertical slider is slidably connected in the rectangular groove.

[0008] As a further technical solution of this utility model, metal side guide frames are symmetrically fixedly connected to the left and right ends of the material conveying frame, and sliding guide blocks are symmetrically fixedly connected to the left and right ends of the motor.

[0009] As a further technical solution of this utility model, the sliding guide block and the metal side guide frame are slidably connected, and an electromagnetic linkage slider is fixedly connected to the end of the sliding guide block away from the motor.

[0010] As a further technical solution of this utility model, the electromagnetic linkage slider is externally connected to a controller, and a weight sensor is fixedly connected to the upper center of the rectangular groove.

[0011] As a further technical solution of this utility model, there is an intermittent magnetic connection between the electromagnetic linkage slider and the inner wall of the metal side guide frame, and multiple equidistant feeding roller shafts are rotatably connected to the upper end of the feeding outer frame.

[0012] As a further technical solution of this utility model, the cross lifting reversing frame rotates up and down and moves vertically within the cross gap of the feeding roller shaft.

[0013] This utility model provides a rotary material rack lifter, which has the following advantages compared with the prior art:

[0014] This rotary material rack lifter features a differentiated state of the inner vertical sliders of the cross-shaped lifting reversing frame during lifting operations. The slider at the material rack contact point is compressed and sinks, while the remaining sliders remain lifted, providing multi-point auxiliary limiting for the material rack and effectively preventing lateral deviation, thus laying the foundation for stable lifting. At the same time, the sliding guide block of the motor and the metal side guide frame of the outer conveyor frame form a rigid guiding engagement, precisely constraining the lifting trajectory of the motor and the cross-shaped lifting reversing frame, counteracting lifting sway, and ensuring no deviation during the lifting process. The reinforced side ribs of the cross-shaped lifting reversing frame enhance the structural strength and prevent structural deformation. When the material rack reaches the target height, the electromagnetic linkage slider is immediately energized and adsorbs the metal side guide frame, temporarily locking the mechanism and avoiding the risk of material falling due to sudden power outages or power fluctuations. This comprehensively improves the reliability and safety of the equipment operation. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution for a rotary material rack lifter: it includes a material conveying outer frame 1, an inner bottom plate 2 fixedly connected to the lower inner wall of the material conveying outer frame 1, electric push rods 3 symmetrically fixedly connected to the upper left and right sides of the inner bottom plate 2, a horizontal top plate 4 installed at the output end of the two electric push rods 3, a motor 5 fixedly connected to the upper middle part of the horizontal top plate 4, a linkage vertical rod 6 installed at the output end of the motor 5, a cross lifting reversing frame 7 fixedly connected to the upper end of the linkage vertical rod 6, a plurality of rectangular grooves 8 opened at the upper end of the cross lifting reversing frame 7, the plurality of rectangular grooves 8 being equidistantly arranged, a telescopic inner rod 16 fixedly connected to the lower inner wall of the rectangular grooves 8, a vertical spring 17 sleeved on the outer end of the telescopic inner rod 16, and an inner vertical slider 9 fixedly connected to the upper end of the telescopic inner rod 16.

[0023] Please see Figures 2-4 The two sides of the cross-lifting reversing frame 7 are symmetrically fixedly connected with reinforcing side ribs 10. The inner vertical slider 9 is slidably connected in the rectangular groove 8. The left and right ends of the material conveying outer frame 1 are symmetrically fixedly connected with metal side guide frames 11. The left and right ends of the motor 5 are symmetrically fixedly connected with sliding guide blocks 12. The sliding guide blocks 12 and the metal side guide frames 11 are slidably connected. This guiding and cooperating structure provides rigid constraints for the lifting of the motor 5 and the cross-lifting reversing frame 7, effectively offsetting the possible shaking during the lifting process. The end of the sliding guide block 12 away from the motor 5 is fixedly connected with an electromagnetic linkage slider 14. The electromagnetic linkage slider 14 is externally connected to a controller.

[0024] Please see Figures 2-4A weight sensor 15 is fixedly connected to the upper center of the rectangular groove 8. The electromagnetic linkage slider 14 and the inner wall of the metal side guide frame 11 are intermittently magnetically connected. Multiple equidistant feeding rollers are rotatably connected to the upper end of the feeding outer frame 1. The cross lifting reversing frame 7 rotates up and down and moves vertically in the cross gap of the feeding rollers.

[0025] The working principle of this utility model is as follows: Before the equipment operates, the conveying roller shaft at the upper end of the conveying outer frame 1 smoothly conveys the material rack to be processed to the top of the cross lifting reversing frame 7. During the lifting operation, the two electric push rods 3 fixed on the inner bottom plate 2 extend and retract synchronously, pushing the top horizontal plate 4 to rise smoothly in the vertical direction. During the lifting process, after the bottom of the material rack contacts the cross lifting reversing frame 7, its own weight will press the inner vertical slider 9 at the corresponding contact position downward in the rectangular groove 8, while the inner vertical slider 9 at other positions that are not in contact with the material rack remains in the lifted state. This differentiated state can form a multi-point auxiliary limiting effect on the material rack, effectively preventing the material rack from shifting laterally during lifting and improving the stability of the operation. The weight sensor 15 at the upper end of the rectangular groove 8 will detect the weight of the material rack in real time and accurately transmit the data to the equipment control system. The system automatically adjusts the output force of the electric push rod 3 according to the weight data. The operating parameters of the motor 5 provide a scientific basis for subsequent power adjustment. The sliding guide blocks 12, which are symmetrically fixed at both ends of the motor 5, will slide precisely along the metal side guide frames 11 fixed at both ends of the material conveying frame 1. This guiding and cooperating structure provides rigid constraints for the lifting of the motor 5 and the cross lifting reversing frame 7, effectively offsetting the possible shaking during the lifting process and ensuring that the entire lifting process is stable and without deviation. The reinforcing side ribs 10 on both sides of the cross lifting reversing frame 7 further enhance its structural strength and prevent deformation due to excessive load on the material frame. When the cross lifting reversing frame 7 lifts the material frame to the target height, the electromagnetic linkage slider 14 at the end of the sliding guide block 12 is immediately energized to generate strong magnetism, which tightly adheres to and fixes to the inner wall of the metal side guide frame 11, realizing the temporary locking of the mechanism and preventing the risk of material falling due to sudden power failure or power fluctuation, thus significantly improving the safety of operation.

[0026] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
