Description

Technical Field

[0001] This application relates to the field of vegetable oil processing machinery and equipment, specifically to a feeding device for an oil press. Background Technology

[0002] In vegetable oil processing production lines, automated feeding of oil presses is a key element in improving efficiency and continuity. Currently, the most common oil press feeding equipment on the market mainly adopts two forms: inclined conveyors (such as belt conveyors) and vertical elevators. While inclined conveyors have a relatively simple structure, their conveying angle is limited, making it difficult to achieve completely vertical or large-angle lifting. This limits their application in oil pressing environments with limited space or requiring high vertical conveying. For vertical feeding needs, the industry commonly uses screw (or spiral, auger) feeders and vacuum feeders. Screw feeders rely on high-speed rotating spiral blades to forcibly push material upwards along a closed pipe. While this method can achieve vertical lifting, the strong extrusion and blade friction process easily cause mechanical damage to oilseed particles, leading to a high breakage rate. Simultaneously, its operation is accompanied by significant mechanical noise. Vacuum feeders utilize negative pressure airflow to suck in and transport oilseeds to a higher position. While they can achieve vertical feeding, the fan system typically generates significant operating noise, and the process of material intake and exhaust inevitably stirs up a large amount of dust, causing environmental pollution and posing certain hygiene hazards. The high breakage rate, high noise levels, and dust pollution associated with vacuum feeders—both of these mainstream vertical feeding devices—all negatively impact subsequent oil pressing processes. Excessive breakage of the oilseeds alters their fluidity and pressure behavior within the pressing chamber, interfering with ideal pressing pressure and oil permeation paths. This can lead to reduced oil yield and affect the color and flavor composition of the oil due to localized overheating or uneven heating.

[0003] Therefore, the current oil pressing industry urgently needs a new type of feeding device that can efficiently achieve vertical feeding and fundamentally solve the problems of high breakage rate, high noise and dust in existing equipment. Utility Model Content

[0004] The purpose of this application is to overcome at least one deficiency of the prior art and provide a feeding device for an oil press that can achieve vertical or large-angle lifting and reduce the breakage rate of oilseeds and operating noise.

[0005] To achieve the above objectives, this application discloses a feeding device for an oil press, which comprises a support frame, a circulating chain transmission mechanism mounted on the support frame, and a plurality of material carrying containers equidistantly arranged on the circulating chain transmission mechanism.

[0006] The support frame is fixedly connected to the external sealing cover to form a closed conveying channel, wherein the circulating chain transmission mechanism includes at least one closed-loop conveying chain, which is driven to circulate by a drive component set on the support frame.

[0007] Each material-carrying container is connected to the conveyor chain via a tail-end double-pivot hinge mechanism, which gives the container the freedom to rotate about its axis.

[0008] The container is equipped with a guide roller assembly at the tail end, and a linear constraint plate extending along the conveying path is set on the support frame. The guide roller assembly and the linear constraint plate form a kinematic pair to maintain the horizontal orientation of the material loading cavity during the conveying process.

[0009] The linear constraint plate is equipped with a termination limit structure near the discharge station to form an overturning station. When the guide roller assembly disengages from the constraint surface of the linear constraint plate, the material carrying container overturns around the axis under the action of gravity.

[0010] The feed inlet is located at the bottom of the enclosed conveying channel and is used to receive raw material input from the front-end storage system. The discharge guide is set at the overturning station at the top of the conveying path and is used to provide a quantitative and continuous material supply to the oil press.

[0011] Furthermore, the circulating chain drive mechanism includes two parallel closed-loop conveyor chains connected by a connector, which are driven by a drive assembly to operate synchronously in a cyclic manner.

[0012] Furthermore, the drive components include an electric motor and a reducer, which drive the conveyor chain to circulate through the main drive shaft of the reducer.

[0013] Furthermore, the material carrying container is provided with a V-shaped cross-section material loading cavity, the opening of which is perpendicular to the conveying plane.

[0014] Compared with the prior art, this application has at least one of the following beneficial technical effects:

[0015] 1. Significantly reduces oil breakage rate: The conveying mode with hopper and guide constraint is adopted to avoid screw-type forced extrusion or vacuum high-speed airflow impact, thus protecting the physical integrity of oil particles to the greatest extent.

[0016] 2. Effectively suppresses operating noise: The chain conveyor mechanism and the guide wheel-guide rail assembly operate smoothly and with low noise, eliminating the friction noise of the high-speed rotation of the screw and the noise of the vacuum system fan.

[0017] 3. Achieve dust-free and sealed conveying: The enclosed working chamber structure completely isolates the conveying process from the external environment, thoroughly solving the problems of dust emission and environmental pollution caused by vacuum material feeding.

[0018] The beneficial effects listed above are not exhaustive of all advantages. Other potential beneficial effects and detailed technical implementation methods will be further disclosed in the embodiments or other descriptive sections of this application. Attached Figure Description

[0029] To better realize the technical solution of the feeding device described in this application, a preferred embodiment is presented in conjunction with the specific structure and operation process. This embodiment adopts a modular, maintainable, and highly sealed structural design, and achieves efficient directional conveying of materials through mechanical coordination.

[0030] See attached document Figures 1 to 5 The feeding device includes a support frame 1, a circulating chain transmission mechanism 2, several material carrying containers 3, and a closed cover 4.

[0031] Specifically, the support frame 1 is a rigid structure used to install the supporting circulating chain transmission mechanism 2 and the material carrying container 3.

[0032] The support frame 1 is equipped with an enclosed cover 4, which extends along the conveying path to form a fully enclosed material conveying channel. The enclosed cover 4 is connected to the support frame 1 by a fastening structure to ensure airtightness and dust isolation performance during operation.

[0033] In this embodiment, the circulating chain transmission mechanism 2 consists of two closed conveyor chains 201 arranged on both sides of the support frame 1. A connecting member connects the two conveyor chains 201 to achieve synchronous movement. The conveyor chains 201 are circulated along the conveying path, and their two ends are respectively connected to a tension wheel assembly and a drive wheel assembly. The drive wheel is located at one end of the conveyor chain 201 and is mechanically connected to the drive assembly, ensuring that the two conveyor chains 201 maintain synchronous drive during operation. Several material carrying containers 3 are equidistantly arranged on the conveying path along the conveyor chain 201. Each material carrying container 3 is movably connected to the connecting space between the left and right conveyor chains 201 or to the conveyor chain 201 itself via a pivot structure located on both sides of its tail.

[0034] More specifically, the drive assembly is mounted on the side of the support frame, transmitting driving force through chains on both sides of the main drive shaft to ensure smooth operation of the entire system during conveying. Sprockets are located at both ends of the drive shaft, meshing with the chains for transmission. The chains drive the attached containers to move synchronously, forming a continuous and uniform conveying process. The movement of the drive assembly is centrally scheduled by the upper-level control system and can be linked with the oil press for control, ensuring that the feeding cycle and process rhythm are synchronized.

[0035] The material carrying container 3 is longitudinally extended and has a V-shaped cross-section material-carrying cavity inside. The opening of the material-carrying cavity faces upward and is perpendicular to the conveying plane of the conveyor chain 201. A guide roller assembly 301 is provided at the tail of the material carrying container 3. The rollers are connected to the outer side of the tail of the material carrying container 3 via a short shaft structure and cooperate with a linear constraint plate 101 correspondingly disposed on the support frame 1. The linear constraint plate 101 is distributed along the conveying path, and its trajectory forms a guiding relationship with the rollers in the guide roller assembly 301. This cooperation constitutes a sliding pair during the movement of the material carrying container 3, which can stably maintain the orientation of the container's material-carrying cavity in a horizontal state.

[0036] The aforementioned linear constraint plate 101 has a termination limit section near the discharge area. At this section, the linear track is interrupted, and the rollers in the guide roller assembly 301 are thus released from the constraint, allowing the material carrying container 3 to naturally tilt around its tail pivot under its own gravity. Because the material carrying container 3 has a rotational degree of freedom in its structural design, the tilting action can quickly unload the material while avoiding damage to the granular raw materials from severe vibration.

[0037] In this embodiment, the feed inlet 5 is located at the bottom starting position of the conveying channel. During implementation, a flexible connection can be formed with the front-end storage system through the interface component to ensure the closed and continuous material input process. The discharge guide port 6 is located near the top end of the enclosed cover 4, directly opposite the unloading path of the flipping end. The discharge guide port 6 has a guide slope and an anti-spillage baffle inside to ensure that the poured material can be smoothly introduced into the oil press feed inlet and to prevent material deviation and splashing.

[0038] Under typical operating conditions, raw materials enter the cavity of the material carrier container 3 located at the bottom through the feed port 5. As the chain moves forward, each material carrier container 3 sequentially enters the guide rail constraint area and is smoothly conveyed along the path. When it reaches the terminal position and is freed from the linear constraint plate 101, the material carrier container 3 automatically tilts to unload, completing the feeding process. The empty container enters the return section with the conveyor chain 201 and returns to the bottom feed section for the next cycle.

[0039] Understandably, through the above structural design, this device can significantly reduce the probability of oil particle breakage during operation, while avoiding particle squeezing and impact problems caused by screw or high-speed pneumatic conveying devices. It is suitable for clean conveying scenarios of various types of particulate materials and has good adaptability and practicality.
