Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of conveying equipment, in particular to a Z-type elevator. BACKGROUND

[0002] In the industrial production fields of food processing and material conveying, the Z-type elevator is widely used in the lifting and transfer operations of various materials due to its small floor space, flexible conveying path and the advantages of realizing vertical and horizontal linkage conveying. Especially in the food processing industry of peanuts and the like, there are higher requirements for the continuity, cleanliness and efficiency of material conveying.

[0003] At present, the mainstream Z-type elevator in the industry is a chain type structure, and its core components include a single driving motor, a driving sprocket, a driven sprocket, a transmission chain and a loading hopper fixed on the chain. The working principle of this type of elevator is that the single driving motor drives the driving sprocket to rotate, thereby driving the transmission chain to move in a cycle, and the loading hopper on the chain moves with the chain. After scooping up the material from the feeding end, the change of the conveying direction is realized through the guidance of multiple driven sprockets, and finally the material is conveyed to the discharging end to complete the transfer. The number of driven sprockets is usually not less than three, and its main function is to realize the turning of the chain in cooperation with the Z-type conveying path, and to ensure the stable movement of the loading hopper along the preset track.

[0004] However, the loading hopper of the existing chain type Z-elevator is fixed on the transmission chain through a connecting piece, and the chain is prone to looseness and deviation in long-term high-speed cycle movement, which leads to a decrease in the connection strength of the loading hopper and the chain, and further causes the loading hopper to fall off, which requires maintenance and seriously affects the continuity of production. The driving force of the entire conveying system is provided by a single motor, and the chain needs to bear the weight of the loading hopper and the material, so the stress load is concentrated, and the chain is prone to stretching deformation, wear and even breakage after long-term operation, which requires frequent replacement of the chain and increases the equipment maintenance cost and downtime. The smooth running of the transmission chain depends on the lubrication of lubricating oil, and in the process of high-speed operation, the lubricating oil on the chain is prone to dripping and splashing, and directly contacts the conveyed material (such as food raw materials such as peanuts), which causes material pollution and violates the clean production standard of the food processing industry.

[0005] Therefore, it is urgent to design a technical solution with low failure rate, which can reduce material pollution and reduce maintenance cost. SUMMARY

Detailed Implementation

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

[0022] The purpose of this invention is to provide a Z-type elevator to solve the problems existing in the prior art, which has a low failure rate and can reduce material contamination and maintenance costs.

[0023] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] In existing chain-type Z-type elevators, the loading bucket is fixed to the drive chain via a connector. However, the chain is prone to loosening and shifting during long-term high-speed cyclic motion, leading to a decrease in the connection strength between the loading bucket and the chain. This can cause the loading bucket to fall, requiring machine shutdown for maintenance and severely impacting production continuity. The smooth operation of the drive chain relies on lubricating oil for lubrication and maintenance. However, during high-speed operation, the lubricating oil on the chain can easily drip and splash, directly contacting the conveyed materials (such as peanuts and other food ingredients), causing material contamination. To solve this problem, this invention provides a Z-type elevator, as described in the reference. Figures 1-7As shown, the device includes a frame 1, a feeding device 3, a discharging device 4, and a loading device 6. The frame 1 has a Z-shaped structure, and a drive device 5 is provided at both the bottom and top ends of the frame 1. The feeding device 3 is located above the drive device 5 at the bottom of the frame 1 and passes through the top wall at the bottom end of the frame 1. The discharging device 4 is located below the drive device 5 at the top of the frame 1 and passes through the bottom wall at the top end of the frame 1. Multiple loading devices 6 are connected in series to form a chain structure and surround the two drive devices 5. The drive devices 5 are connected to the loading devices 6 to drive the multiple loading devices 6 in the chain structure to rotate. The feed inlet of the loading device 6 is located on the outside of the chain structure. Material falls through the feeding device 3 and into the loading device 6, which is positioned directly below the feeding device 3. It then moves along the chain structure of the loading device 6 to the top of the frame 1. When the material inlet of the loading device 6 is directly above the discharge device 4, the material falls into the discharge device 4 and is discharged. This invention uses two drive devices 5 arranged vertically for synchronous drive, effectively reducing the load on the loading device 6, thereby reducing the failure rate, increasing the rotational speed, and improving material lifting efficiency. The loading devices 6, connected in a chain structure, replace the chain, thus solving the problem of the loading hopper 601 falling due to chain swaying. Existing chain elevators require lubrication and maintenance of the chain, which can easily contaminate the material during operation. This invention eliminates the chain, directly using multiple loading devices 6 connected in a chain structure, eliminating the need for lubrication and avoiding contamination problems caused by chain lubrication.

[0025] In one embodiment, the frame 1 is a hollow shell structure, including a vertical frame 103 and a horizontally arranged top frame 101 and bottom frame 102. One end of the top frame 101 is connected to the top of the vertical frame 103, and one end of the bottom frame 102 is connected to the bottom of the vertical frame 103, forming a Z-shaped structure. The discharge device 4 is located at the end of the top frame 101 away from the vertical frame 103, and the feeding device 3 is located at the end of the bottom frame 102 away from the vertical frame 103.

[0026] In one embodiment, to eliminate the need for a chain, the loading device 6 of this embodiment includes a loading hopper 601, a roller 602, and a connecting rod 603. The loading hopper 601 is arranged at an angle, and a connecting through hole 605 is provided on one side of the top of the loading hopper 601. Two extension plates 604 are symmetrically arranged on the side of the loading hopper 601 away from the connecting through hole 605. The connecting rod 603 passes through the two extension plates 604, and the end of the connecting rod 603 passes through the adjacent extension plate 604 and is connected to the roller 602. The part of the connecting rod 603 located between the two extension plates 604 is movably inserted into the connecting through hole 605 of another adjacent loading device, thereby realizing the connection of the two loading devices. The end of the connecting rod 603 is provided with a gasket and a limiting pin. The roller 602 is located between the gasket and the positioning pin, which can prevent the roller 602 from falling off during operation. The roller can be connected to the drive device 5 for transmission. The drive device 5 moves the roller, thereby driving the hopper 601 and the extension plate to move sequentially along their chain structure to realize the material conveying process.

[0027] In one embodiment, a steering device 2 is provided on the inner side of the connection position between the top frame 101 and the bottom frame 102, and a steering device 2 is provided on the inner side of the connection position between the bottom frame 102 and the top frame 101. The steering device 2 in this embodiment includes an arc-shaped guide rail with a U-shaped cross-section. Guide rails are provided at the upper and lower corner positions of the top frame 101 and the vertical frame 103, and the centers of the virtual circles containing the two guide rails are the same. Similarly, guide rails are provided at the upper and lower corner positions of the bottom frame 102 and the vertical frame 103, and the centers of the virtual circles containing the two guide rails are the same. This structural arrangement allows the chain structure formed by the loading device 6 to be smoothly guided and transitioned at both the upward and downward corner positions. The rollers at both ends of the connecting rod 603 can be rolled and connected to the guide rail on the same side, and the connecting rod 603 extends from the open end of the U-shaped structure, so that no interference occurs during the movement and turning along the guide rail. Steering device 2 uses a guide rail instead of a driven sprocket for steering, which reduces moving parts and lowers the mechanical failure rate.

[0028] In one embodiment, the driving device 5 includes a driving motor and a driving wheel. The output shaft of the driving motor is driven by the driving wheel, and the driving wheel can be driven by the roller. In another embodiment, a driving shaft is rotatably mounted on both the top frame 101 and the bottom frame 102. One end of the driving shaft is driven by the output shaft of the corresponding driving motor, and both ends of the driving shaft are fitted with driving wheels, which can be synchronously driven by the rollers at both ends of the connecting rod 603. To improve the transmission effect, a driving disc 501 is fixedly mounted on the outside of the driving wheel in this embodiment. Multiple actuation grooves 502 are sequentially opened on the outer edge of the driving disc 501. The sidewalls of the actuation grooves 502 are arranged at an incline, and the actuation grooves 502 can accommodate the rollers 602. During the rotation of the driving disc 501, the rollers 602 located in the actuation grooves 502 can be actuated, so that the rollers 602 of the multiple loading devices 6 sequentially enter the respective actuation grooves 502 and are actuated forward by the sidewalls of the actuation grooves 502, so that the rollers 602 drive the loading devices 6 to move cyclically, thereby realizing the conveying of materials.

[0029] In one embodiment, a tensioning device 7 is provided on the side wall of the base frame. The tensioning device 7 is connected to the drive device 5 located at the base frame position. The tensioning device 7 can adjust the horizontal position of the drive device 5 to change the tension of the chain structure of multiple loading devices 6 connected in series. In this embodiment, the tensioning device 7 includes slides fixed on both sides of the base frame. A groove is opened in the slide through the side wall of the base frame. A slider is provided in the slide and a bearing is connected to the slider. The drive shaft of the drive device 5 passes through the bearing. A cylinder is connected to the slider on one side. The fixed end of the cylinder is installed on the side wall of the base frame. A cylinder is also connected to the slider on the other side. The fixed end of the cylinder is installed on the side wall of the other side of the base frame. The drive motor is fixed to the slider on one side of the base frame. The output ends of the two cylinders extend and retract synchronously, which can drive the drive device 5 to move horizontally synchronously, thereby realizing its tensioning function on the chain structure formed by the loading devices 6 of the present invention and preventing the loading devices from being too tight or too loose due to thermal expansion and contraction.

[0030] In one embodiment, the feeding device 3 includes a feeding hopper, the bottom of which penetrates the top wall of one end of the base frame 102, and the top opening of the feeding hopper is larger than the bottom opening for easy feeding. The discharging device 4 includes a discharging hopper, the top of which penetrates the bottom wall of one end of the top frame 101, and the top opening of the discharging hopper is smaller than the bottom opening for easy discharging. The material enters the loading hopper 601 directly below it via the feeding device 3. The loading hopper 601 is driven by the driving device 5, and its direction is adjusted by the steering device 2 to reach the discharging device 4, where the material is discharged. After discharging the material, the loading hopper 601 rotates back to the position of the feeding device 3 for reloading, thus realizing the cyclical conveying of materials.

[0031] Existing chain-type lifting mechanisms use sprockets to drive chains, which in turn move the hoppers 601. The hoppers 601 are positioned between two chains; when the chains sway, the hoppers 601 are prone to detaching, causing malfunctions. This invention solves this problem by interconnecting the hoppers 601, eliminating the need for chains. Because the chains are eliminated, lubrication and maintenance are unnecessary, and lubricating oil dripping will not contaminate the material during operation. This invention uses two synchronously driven devices 5, reducing the force-bearing distance and lowering the load. This invention uses a guide rail instead of the driven sprocket as the steering device 2, simplifying the structure, reducing malfunctions, and thus significantly increasing the equipment's operating speed and improving material lifting efficiency.

[0032] Specific examples have been used to illustrate the principles and implementation methods of this invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this invention. Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this invention.
