Description

Technical Field

[0001] This utility model relates to the technical field of rotary material gate equipment, specifically a rotary material feeding proportional gate. Background Technology

[0002] Quick-return conveyors are a type of high-efficiency material handling equipment widely used in food, chemical, and mining industries. They feature low breakage rates, high stability, and flexible control. However, most existing quick-return conveyors guide materials through reciprocating motion, which makes it inconvenient to unload materials proportionally according to user needs, thus reducing the practical performance of quick-return conveyors. Therefore, there is an urgent need for a rotary discharge proportional gate to solve the above-mentioned problems. Utility Model Content

[0003] The purpose of this invention is to provide a rotary feeding proportional gate to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a rotary feeding proportional gate, comprising a guide frame for support, a groove frame one located at one end of the guide frame, and a groove frame two located at the other end of the guide frame, a motor retainer for limiting movement located at the rear of the groove frame one and the groove frame two, and a motor protective cover located at the rear end face of the motor retainer, both the groove frame one and the groove frame two having a cover rotatably engaged inside, and two sets of pressure rollers located on the upper part of the inner end face of the cover. The plastic guide rail is provided in two sets. One set of the plastic guide rail is set inside the groove frame, and the other set of the plastic guide rail is set inside the groove frame. The unloading device is rotatably engaged with the front of the guide frame via the plastic guide rail, and is used for proportional unloading. A clamping plate is fixedly disposed on the inner end face side wall of the motor retainer. A speed reducer is disposed at the rear of the clamping plate, and a servo motor is disposed at the input end of the speed reducer. A gear is disposed at the output end of the speed reducer.

[0005] Preferably, the unloading device includes a roller housing for support, a handle is provided on the side end face of the roller housing, and a material guide opening is provided at the middle of the side end face of the roller housing. An annular toothed rack is provided on the side end face of the roller housing near the front.

[0006] Preferably, the cover drives the two sets of pressure rollers to press against the upper end face of the roller housing, which can improve the stability of the roller housing rotating inside the plastic guide rail.

[0007] Preferably, the gear drives the roller housing to rotate via the annular rack, which can improve the accuracy and stability of subsequent control of the material guide opening rotation.

[0008] Preferably, the roller shell is rotatably engaged with the two sets of plastic guide rails, which can improve the stability of the roller shell rotating inside the plastic guide rails and improve the accuracy of subsequent proportional unloading.

[0009] Preferably, the first and second trough frames are coaxial with the roller shell, which can effectively improve the accuracy and stability of subsequent material unloading and guiding.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. When materials are needed at both points A and B, the proportional gate at point A can be opened only 1 / 3 or a set value, so that the remaining materials after passing through A can flow smoothly to point B. This prevents the proportional gate at point A from being fully opened and leaving no materials after point A, which would cause point B to wait for a long time when it needs materials, thus greatly improving the conveying efficiency.

[0011] 2. The rotary proportional gate in this utility model optimizes the unloading method. In the past, the material gate's pull-out plate might crush or damage the material at the moment of closing. Here, a rotary method is used, so the rotary proportional gate does not damage the material when opening or closing, thus improving the protection performance of the discharged material.

[0012] 3. When the drum shell of this utility model is rotated open, the material may come into contact with the guide frame. Since the inner side of the guide frame is flat, the material will not accumulate there, thus improving the efficiency of the equipment in guiding the material.

[0013] 4. When cleaning the roller housing, the cover can be opened and the roller housing can be removed from the top using the handle welded on it. Then, the two plastic guide rails can be removed, which improves the convenience of disassembly.

[0014] 5. The roller shell of this utility model is made of 304 stainless steel, and plastic gears are made at both ends. They are interference-fitted with the roller shell by temperature difference method, eliminating the need for screws and avoiding the accumulation of material dust at the screws, thus improving the cleaning performance of the roller shell.
