Description
Technical Field
[0001] This utility model relates to the technical field of material conveying equipment for factory production lines, specifically a feeding mechanism that relies on the rotation of the material box by its own weight. Background Technology
[0002] In modern factory production lines, an efficient material handling system is a key element in ensuring smooth production processes. However, many factories today face the challenge of complex floor space layouts, with work areas and material delivery points often not aligned. Under traditional material handling methods, manually moving material boxes back and forth becomes a heavy and inefficient task. Workers need to frequently travel between the delivery point and the work area, consuming significant physical strength and time, and easily leading to fatigue and further reduced work efficiency, while also keeping labor costs high.
[0003] On the other hand, while ordinary conveyor belts have certain advantages in linear material transport, they are mostly linear structures and cannot flexibly adapt to complex spatial layouts. When it is necessary to change the direction of material transport, ordinary conveyor belts often cannot meet the requirements.
[0004] Therefore, it is urgent to develop a device that can efficiently turn and transport material boxes within a limited space. This is of great practical significance for improving factory production efficiency, reducing labor costs, and optimizing production processes. Utility Model Content
[0005] The purpose of this invention is to provide a feeding mechanism that allows the material bin to rotate under its own weight, thereby solving the problems of difficult and inefficient material handling caused by space constraints in factory production lines. This feeding mechanism enables the material bin to rotate and be transported by its own weight, thus saving manual handling effort and significantly improving the efficiency of material conveying on the production line. This solves the technical problems in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding mechanism that rotates by the weight of the material box, comprising a feeding section material rack, a steering material rack, and a discharging section material rack arranged from high to low.
[0007] The top of the feeding section material rack, the turning material rack, and the discharging section material rack are all equipped with lean pipe flow strips for conveying material boxes; the turning material rack is rotatably equipped with a turning frame, which receives the material box conveyed by the feeding section material rack and, after rotation, transfers the material box to the discharging section material rack.
[0008] It also includes a reset structure, which is connected to the bogie. When the bogie transfers the material box to the material rack in the discharge section, the reset structure drives the bogie to reset, so that the feeding end of the bogie is realigned with the material rack in the feeding section.
[0009] Furthermore, the steering material rack includes a bogie, bearings, an inclined fixing frame, and a rotating shaft;
[0010] The inclined fixing frame is inclinedly fixed to the upper part of the turning material rack as a fixed base for the bearing;
[0011] The bearing is mounted on an inclined frame and has the same inclination angle as the inclined frame. The rotating shaft passes through the bearing. The upper part of the rotating shaft is fixedly connected to the bottom of the bogie. The rotating shaft and the bogie also have a certain downward inclination angle.
[0012] Furthermore, the reset structure includes a pulley, a counterweight, and a stainless steel-coated rope;
[0013] The pulley is fixed to the side of the material rack in the feeding section. One end of the stainless steel plastic-coated rope is connected to the bogie, and the other end passes around the pulley and is connected to the counterweight bar.
[0014] The counterweight bar pulls the lower end of the stainless steel-coated rope downwards under the action of gravity; after the stainless steel-coated rope changes direction through the pulley, it is connected to the bogie and provides the tension for the bogie to return to its original position.
[0015] Furthermore, it also includes a blocking structure; the blocking structure includes a limiting rod and a stop rod; the limiting rod is hinged to the end of the bogie; the stop rod is fixed to the material rack of the discharge section on the side near the bogie;
[0016] The upper middle part of the limiting rod is hinged to the tail part of the limiting rod. The lower part of the limiting rod is heavier than the upper part. Under normal conditions, the limiting rod is in a vertical state under the action of gravity.
[0017] Furthermore, it also includes two limiting plates fixed to the steering material rack, with the two limiting plates respectively set at the initial and final positions of the bogie's rotational movement.
[0018] Beneficial effects
[0019] This invention achieves turning and transmission by the weight of the material box, eliminating the need for manual handling, saving time and labor costs in material handling, and significantly improving the material conveying efficiency of the factory production line.
[0020] The steering design of this utility model can adapt well to the complex spatial layout of the factory site, solve the problem of material transportation where the work area and the logistics feeding port are not on the same straight line, and improve the space utilization rate.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] To achieve the above objectives, this utility model provides the following technical solution, such as... Figure 1-4 As shown, a feeding mechanism that rotates by the weight of the material box is characterized by comprising a feeding section material rack 1, a steering material rack 2, a discharging section material rack 3, and a reset structure 4 arranged from high to low.
[0030] The tops of the feeding section material rack 1, the turning material rack 2, and the discharging section material rack 3 are all equipped with lean pipe flow strips 6 for conveying material boxes. In this embodiment, taking the need for the feeding mechanism to change the conveying direction of the material by 90 degrees as an example, different angles can be adjusted according to the actual situation on site in actual use. In order to achieve the purpose of changing the conveying direction, in this embodiment, the feeding section material rack 1 and the discharging section material rack 3 are set at a 90-degree angle. The turning material rack 2 is equipped with a turning frame 21, which can rotate at a 90-degree angle to receive the material boxes conveyed by the feeding section material rack 1, and transfer the material boxes to the discharging section material rack 3 after rotating 90 degrees. This completes the material box transfer work and changes the movement trajectory of the material boxes, allowing the material boxes to turn according to the setting direction of the feeding mechanism.
[0031] The reset structure 4 is connected to the bogie 21. When the bogie 21 transfers the material box to the material rack 3 of the discharge section, the reset structure 4 drives the bogie 21 to reset, so that the feeding end of the bogie 21 is aligned with the material rack 1 of the feeding section, ready to receive the next material box.
[0032] Furthermore, the steering material rack 2 includes a bogie 21, a bearing 22, an inclined fixing frame 23, and a rotating shaft 24;
[0033] The inclined fixing bracket 23 is inclinedly fixed on the upper part of the turning material rack 2 and used as a fixing base for the bearing 22. The inclined fixing bracket 23 is inclined downward in the direction away from the feeding part material rack 1 and the discharging part material rack 3.
[0034] The bearing 22 is mounted on the inclined fixing frame 23 and has the same tilt angle as the inclined fixing frame 23. The rotating shaft 24 passes through the bearing 22. The upper part of the rotating shaft 24 is fixedly connected to the bottom of the bogie 21. The rotating shaft 24 and the bogie 21 also have a certain downward tilt angle.
[0035] It should be noted that the connection position between the upper part of the rotating shaft 24 and the bogie 21 is not the center position of the bottom of the bogie 21. The connection position is on the side of the bottom of the bogie 21 near the material rack 1 of the feeding section. The purpose of this design is that, in conjunction with the inclined rotating shaft 24, the bogie 21 can rotate centrifugally around the rotating shaft 24 as the axis by gravity, and has a tendency to move towards the material rack 3 of the discharge section.
[0036] Furthermore, the reset structure 4 includes a pulley 41, a counterweight 42, and a stainless steel plastic-coated rope 43;
[0037] The pulley 41 is fixed to the side of the material rack 1 in the feeding section. One end of the stainless steel plastic-coated rope 43 is connected to the bogie 21, and the other end passes around the pulley 41 and is connected to the counterweight bar 42.
[0038] The counterweight 42 pulls the lower end of the stainless steel coated rope 43 downwards under the action of gravity. After the stainless steel coated rope 43 changes direction through the pulley 41, it is connected to the bogie 21 and provides the bogie 21 with the tension to reset. In the initial state, the counterweight 42 has a certain weight, and the tension it provides can counteract the rotation trend of the bogie 21, so that the feeding end of the bogie 21 faces the feeding section material rack 1, ready to receive the material box being conveyed. When the material box is conveyed to the bogie 21, the balance is broken due to the addition of the weight of the material box. The bogie 21 starts to rotate 90 degrees and aligns with the discharging section material rack 3. Finally, the material box slides onto the discharging section material rack 3. When the material box leaves the bogie 21, the tension provided by the counterweight 42 can again counteract the rotation trend of the bogie 21 and pull the bogie 21 to reset, ready to receive the next material box.
[0039] Furthermore, it also includes a blocking structure 5, which is used to control the material box that has a downward sliding tendency when the material box is transferred to the bogie 21; when the blocking structure 5 is in the locked state, the material box is blocked at the end of the bogie 21 and cannot enter the material rack 3 of the discharge section; when the blocking structure 5 is in the open state, the material box is released and the material box continues to move to the material rack 3 of the discharge section under the action of gravity.
[0040] The blocking structure 5 includes a limiting rod 51 and a stop rod 52; the limiting rod 51 is hinged to the end of the bogie 21; the stop rod 52 is fixed on the material rack 3 of the discharge section near the side of the bogie 21.
[0041] The upper middle part of the limiting rod 51 is hinged to the tail part of the limiting rod 51. The lower part of the limiting rod 51 is heavier than the upper part. Under normal conditions, the limiting rod 51 is in a vertical state under the action of gravity. At this time, the blocking structure 5 is in a locked state, and the material box is blocked at the end of the bogie 21. When the bogie 21 gradually rotates to the material rack 3 of the discharge section under the gravity of the material box, the lower part of the limiting rod 51 contacts the stop bar 52. The lower part of the limiting rod 51 is blocked by the stop bar 52 on the material rack 3 of the discharge section, causing the limiting rod 51 to tilt. When the top of the limiting rod 51 is lower than the bottom of the material box, the material box is released. The material box continues to move to the material rack 3 of the discharge section under the action of gravity.
[0042] Initially, the material box is placed on the material rack 1 of the feeding section. Under the action of gravity, the material box slides along the material rack 1 of the feeding section to the turning material rack 2. Then, the turning material rack 2 receives the material box from the material rack 1 of the feeding section. Under the action of the gravity of the material box, the turning frame 21 gradually rotates 90 degrees and then connects with the material rack 3 of the discharging section. During this process, the material box slides to the tail of the turning material rack 2 and is blocked by the top of the limiting rod 51 on the turning material rack 2. The limiting rod 51 is rotatably set at the tail of the turning material rack 2. The limiting rod 51 is initially in a vertical state. When the turning material rack 2 gradually rotates 90 degrees, the lower part of the limiting rod 51 is blocked by the stop bar 52 on the material rack 3 of the discharging section, causing the limiting rod 51 to rotate.
[0043] Furthermore, it also includes two limiting plates fixed to the steering material rack 2, with the two limiting plates respectively set at the initial and final positions of the rotational movement of the bogie 21.
[0044] The working principle and process are as follows:
[0045] Initially, the material box is placed on the material rack 1 of the feeding section. Due to the certain inclination of the lean pipe flow bar 6 at the top of the material rack 1, the material box slides along the lean pipe flow bar 6 towards the turning material rack 2 under its own gravity. During the sliding process, the speed and stability of the material box are ensured by the inclination of the lean pipe flow bar 6 and the performance of the rollers.
[0046] When the material box reaches the turning material rack 2, due to the weight of the material box and the special connection between the turning rack 21 and the rotating shaft 24 (the connection position of the rotating shaft 24 and the turning rack 21 is close to the material rack 1 of the feeding section, and both have a downward tilt angle), the turning rack 21 begins to gradually rotate 90 degrees around the rotating shaft 24 as the axis under the gravity of the material box. During the rotation, the material box moves together with the turning rack 21 and slides to the rear of the turning rack 21. At this time, the limiting rod 51 at the rear of the turning rack 21 is in a vertical state, blocking the material box at the end of the turning rack 21 and preventing the material box from slipping off prematurely.
[0047] As the bogie 21 gradually rotates 90 degrees, it aligns with the material rack 3 in the discharge section. During the alignment process, the lower part of the limiting rod 51 on the bogie 21 contacts the stop rod 52 on the material rack 3 in the discharge section. The stop rod 52 blocks the lower part of the limiting rod 51, causing the limiting rod 51 to tilt. When the top of the limiting rod 51 is lower than the bottom of the material box, the material box is released and continues to move along the lean pipe flow bar 6 at the top of the material rack 3 in the discharge section under the action of gravity. Finally, the material box is conveyed outward along the material rack 3 in the discharge section to the designated position.
[0048] After the material box leaves the bogie 21, the counterweight bar 42 pulls the stainless steel coated rope 43 downwards under the action of gravity. After the stainless steel coated rope 43 changes direction through the pulley 41, it provides a resetting force for the bogie 21. Under the action of the force, the bogie 21 overcomes its own rotational inertia and gradually resets, so that the feeding end of the bogie 21 is aligned again with the material rack 1 of the feeding section, ready to receive the next material box. During the resetting process, the lower part of the limit rod 51 gradually moves away from the stop rod 52, and the limit rod 51 also gradually returns to a vertical state under its own gravity.
[0049] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
