Description

Technical Field

[0001] The utility model relates to the field of material conveying and packaging equipment, in particular to a cup-type elevator. Background Art

[0002] During the packaging process of materials or foods, it is necessary to package the materials in a quantitative manner, especially some bulk foods such as meat blocks. The traditional method is to put the materials directly into the hopper and control the output by controlling the opening and closing time of the hopper mouth. Since the pressure of the hopper outlet gradually decreases as the hopper load decreases, and bulk materials (such as meat products) are easily blocked and require manual intervention, the hopper mouth leads to unstable output per unit time, resulting in large differences in the amount of packaging carried by the packaging bag. The specifications of the packaging bags are different, which affects the independent sale of the products. Existing elevators (such as chain bucket type and belt type) cannot complete metering and transportation simultaneously. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a cup elevator, the purpose of which is to pour a quantitative amount of material into a measuring cup and output it from the hopper one by one, thereby ensuring that the output amount of the hopper each time remains consistent.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cup-type elevator, comprising a frame, a loading platform and a unloading platform located higher than the loading platform are provided on the frame, a lifting mechanism is provided between the loading platform and the unloading platform, a hopper is provided at the output end of the unloading platform, a swingable feed pipe is provided above the hopper, and a measuring cup is also provided. The measuring cup is flipped 180 degrees by the flipping mechanism and enters the feed pipe for dumping materials and pouring the measuring cup into the feed pipe at the same time, a return slide is provided between the feed pipe and the loading platform, and a closed-loop transmission path for the measuring cup is formed between the loading platform, the lifting mechanism, the unloading platform and the return slide.

[0005] The loading platform is provided with a first conveyor belt, a second conveyor belt and a third conveyor belt. A "U"-shaped limiting channel surrounded by steel wire is provided on the upper portion of the loading platform. A first conveyor belt is provided on one side of the "U"-shaped limiting channel, and a second conveyor belt is provided on the other side of the "U"-shaped limiting channel. The first conveyor belt and the second conveyor belt are provided in parallel and convey in opposite directions. An output platform is provided at the output of the "U"-shaped limiting channel, and limiting rods are provided on both sides of the output platform. The third conveyor belt is provided on the surface of the output platform, and the output end of the third conveyor belt is aligned with the entrance of the lifting mechanism. In this way, when a worker stands at the loading platform, the worker weighs or quantifies the material and pours it into the measuring cup on the loading platform. The measuring cup slides in from the left side of the "U"-shaped limiting channel and is output from the outlet on the right side. This gives the worker sufficient time to load the material. The loaded measuring cup then enters the third conveyor belt and is arranged in sequence, ready to enter the unloading platform through the lifting mechanism.

[0006] The lifting mechanism includes a surrounding lifting chain, which is installed on a lifting sprocket, which is driven by a lifting motor. There are evenly distributed trays on the chain, and the bottom size of the tray is smaller than the bottom size of the measuring cup. The front end of the tray is bent upward to form a limit hook to prevent the measuring cup from leaving the tray. The rising stage of the tray passes through the loading platform, and the lowering stage of the tray passes through the unloading platform. A rotating cylinder is installed on the loading platform, and the output shaft of the rotating cylinder is connected to a swing arm. A shifting groove is provided on the swing arm. The measuring cups arranged at the front end are stuck in the shifting groove and then quickly enter the tray through the swinging of the swing arm. A bottom plate is provided between the loading platform and the rising path of the tray. Two surrounding material receiving chains are arranged on the unloading platform. When the tray descends and passes through the gap between the two material receiving chains, the measuring cups on the tray are placed on the material receiving chain for output. The two material receiving chains are driven by a material receiving motor. When the pallet rises and approaches the pallet, the rotating cylinder drives the swing arm to scrape the measuring cups arranged on the third conveyor belt onto the rising pallet. Then the pallet lifts the measuring cups to the top of the lifting chain and moves down. When the pallet passes the two connecting chains, the measuring cups fall onto the connecting chain and are output and transported along the direction of the unloading platform.

[0007] Block rods are respectively provided on both sides of the unloading platform, and a fourth conveyor belt is arranged on the unloading platform. A blocking motor is arranged on one side of the output end of the unloading platform, and a positioning rod is installed on the output shaft of the blocking motor, which is in a "V" shape. A discharge trough is provided at the output end of the unloading platform, and a turning cylinder is installed on the side wall of the discharge trough. A turning plate is connected to the output shaft of the turning cylinder, and the cross-section of the turning plate is in an "L" shape. When not turned over, the bottom plate of the turning plate is flush with the end face of the unloading platform, and the outer diameter of the lower part of the feeding pipe is smaller than the outer diameter of the upper part thereof. The lower part of the feeding pipe is inserted in a rotating ring, and the rotating ring is rotatably installed in the discharge trough through a rotating shaft. A swing rod is connected to one end of the rotating shaft, and an adjustment rod is provided on the swing rod. The frame is provided with a swing cylinder, and the piston rod of the swing cylinder is adjustably connected to the adjusting slot on the rocker arm through the adjusting bolt position, so that the swing angle of the rotating ring can be controlled. The upper end of the feed pipe is provided with an extended edge guard on the side away from the fourth conveyor belt. After the flip plate is flipped, the measuring cup can contact the edge guard to prevent it from leaving the center hole position of the feed pipe. A cup baffle plate is also set in the discharge chute. The inner diameter of the perforation of the cup baffle plate is smaller than the outer diameter of the measuring cup, so that the measuring cup will not fall into the hopper with the material. After the feed pipe and the measuring cup contact the cup baffle plate, when the rotating ring drives the feed pipe to rotate toward the entrance of the return slide, the feed pipe will retract along the inner hole of the rotating ring, so that the measuring cup slides out of the feed pipe and enters the return slide.

[0008] The return slide consists of a protective plate, a frame, and guide wires. The protective plate and several frames are mounted on the frame, and multiple guide wires are connected to the frame. The protective plate is connected to the bottom of the frame. The guide wires form a slide for the measuring cup to slide along. The measuring cup slides along the slide to the loading platform.

[0009] How this device works:

[0010] 1. Loading process: After the worker puts the material into the measuring cup, it is aligned in the limiting channel through the first and second conveyor belts and then transported to the lifting mechanism by the third conveyor belt;

[0011] 2. Lifting process: After the pallet receives the measuring cup, it is lifted to the unloading platform via the lifting chain;

[0012] 3. Unloading process: After the positioning rod is positioned, the flip plate tilts the measuring cup, and the material enters the hopper through the conveying pipe;

[0013] 4. Return link: The empty measuring cup slides back to the loading platform through the guide wire of the return slide.

[0014] The beneficial effect of the utility model is that a closed-loop transmission path for the measuring cup is formed between the loading platform, the lifting mechanism, the unloading platform, and the return slide. When the measuring cup passes the loading platform, the worker adds a quantitative amount of material into the passing measuring cup, and then enters the unloading platform through the lifting mechanism. The measuring cup is on the unloading platform, and the measuring cup is turned 180 degrees by the turning mechanism to enter the feeding pipe. In this way, the material is poured into the feeding pipe and output through the hopper. The feeding pipe then swings to slide the measuring cup into the return slide and return to the loading platform. This is repeated, so as to achieve the goal of pouring a quantitative amount of material into the measuring cup and outputting it from the hopper one by one, thereby ensuring that the output amount of the hopper each time remains consistent.
