Description

Technical Field

[0001] This invention relates to the technical field of peeling machine components, specifically to a grooved spiral rubber roller assembly for a plant tuber peeling machine. Background Technology

[0002] The peeling process of plant tubers is generally divided into manual and mechanical methods. Manual methods are time-consuming, labor-intensive, inefficient, and difficult to meet the requirements of industrial-scale production.

[0003] Regarding mechanical desquamation of plant tubers, the following Chinese patent documents disclose:

[0004] Reference 1, A high-efficiency corn peeling machine (201410385907.4): The spiral peeling roller is covered with a rubber cylinder, and the rubber cylinder is wound with spiral rubber ribs. The spiral rubber ribs are embedded with spring washers to adapt to the shape of the corn cob and make contact with the corn cob from multiple directions.

[0005] Reference 2, Automated and efficient nut peeling device (201310294250.6): Two peeling rollers are installed side by side on the frame, and there is a pusher screw on the peeling rollers.

[0006] Reference 3, A potato peeling mechanism and peeling machine (201820409752.7): A brush roller and at least two separated sanding rollers form an arc-shaped groove, and the potatoes peeled by the sanding roller and the brush roller are washed by spraying water through a spray pipe.

[0007] The aforementioned literature primarily employs friction to achieve the peeling operation, without considering the effect of water scouring during the peeling process, and further neglecting to consider improved designs for the peeling roller structure that can transform the jet water flow into a turbulent water flow. Therefore, the peeling effect is relatively low. Summary of the Invention

[0008] The purpose of this invention is to provide a grooved spiral rubber roller for a plant tuber peeling machine with better peeling efficiency. The design aims to combine the water flow sprayed from the nozzle with the V-shaped groove of the rubber roller to generate great turbulence, so that the material will continuously roll and collide during the spiral propulsion process, forming a water-cutting peeling method.

[0009] The objective of this invention is achieved as follows: a grooved spiral rubber roller for a plant tuber peeling machine using water-cutting peeling, characterized in that the grooved spiral rubber roller has the following structure: a shaft is fixed at each end of a steel cylinder, a polyurethane layer or a rubber layer is covered on the steel cylinder, a plurality of V-shaped grooves are evenly distributed on the polyurethane layer or rubber layer along the axis, and a spiral groove is provided on the polyurethane layer or rubber layer, a polyurethane strip or rubber strip is embedded and bonded in the spiral groove and protrudes from the polyurethane layer or rubber layer, or, the polyurethane layer or rubber layer has an outwardly protruding, integrally formed spiral strip.

[0010] The polyurethane layer or rubber layer has a thickness of 8mm, the V-groove has a depth of 4mm, an opening width of 4.36mm, and the pitch of the spiral groove or spiral strip is 50mm.

[0011] The grooved spiral rubber roller has a length of 1200mm and a diameter of 92mm.

[0012] The grooved rubber rollers are two or more, and the two or more grooved spiral rubber rollers are respectively mounted on the frame by a pair of bearings. The centerlines of all the grooved spiral rubber rollers are located in the same plane and are driven by the drive device to rotate in the same direction.

[0013] Another objective of this invention is to provide a grooved spiral rubber roller assembly for a plant tuber peeling machine with better peeling efficiency. The aim is to combine the water flow sprayed from the nozzle with the V-shaped groove of the rubber roller to generate great turbulence, so that the material continuously rolls, collides and rubs during the spiral pushing process, thereby forming a water-cutting peeling method that also has a rotary cutting friction peeling method between adjacent rubber rollers.

[0014] The objective of this invention is achieved as follows: a grooved spiral rubber roller assembly for a plant tuber peeling machine, comprising three identical grooved spiral rubber rollers mounted on a frame via a pair of bearings, with the three axis lines of the three grooved spiral rubber rollers located in the same plane; the structure of each grooved spiral rubber roller is as follows: a shaft is fixed at each end of a steel cylinder, a polyurethane layer or rubber layer is covered on the steel cylinder, several V-shaped grooves are evenly distributed along the axis line on the polyurethane layer or rubber layer, and a spiral groove is provided on the polyurethane layer or rubber layer, a polyurethane strip or rubber strip is embedded and bonded in the spiral groove and protrudes from the polyurethane layer or rubber layer, or, the polyurethane layer or rubber layer has an outwardly protruding, integrally formed spiral strip;

[0015] The motor is mounted on the base plate of the frame. The first drive sprocket on the motor shaft drives the first driven sprocket via a chain. The second drive sprocket, which is coaxial with the first driven sprocket, drives the second driven sprocket via a chain. The third drive sprocket, which is coaxial with the second driven sprocket, drives the third driven sprocket via a chain. The right ends of the three shafts of the three grooved spiral rubber rollers are respectively connected to the first driven sprocket, the third drive sprocket, and the third driven sprocket. The first driven sprocket, the second drive sprocket, the second driven sprocket, the third drive sprocket, and the third driven sprocket are all identical.

[0016] The polyurethane layer or rubber layer has a thickness of 8mm, the V-groove has a depth of 4mm, an opening width of 4.36mm, and the pitch of the spiral groove or spiral strip is 50mm.

[0017] The grooved spiral rubber roller has a length of 1200mm and a diameter of 92mm.

[0018] Compared with the prior art, the present invention has the following features and advantages:

[0019] 1. Compared with existing peeling rollers that rely solely on friction to peel plant tubers, this invention has a better peeling effect.

[0020] The peeling mechanism of this assembly is as follows: The three grooved spiral rubber rollers, the working components of the peeling machine, rotate in the same direction and at the same speed. The spiral rubber strips on the rollers push the material, and friction between the spiral rubber strips, the rubber layer, and the material generates a peeling effect during relative motion. Especially when combined with a water spray system, pressurized water is sprayed out in the form of water jets. Under the pressure of the pressurized water, the V-shaped grooves on the rollers and the spiral rubber strips create turbulent water flow in the material channel. Throughout the peeling process, as the material, such as irregularly shaped tubers of Aconitum carmichaelii, moves forward via the spiral pusher, the high-pressure water's scouring force, combined with the shearing effect of the V-shaped grooves on the rollers, creates significant turbulence in the water flow. Within this turbulence, vortices of varying sizes are formed. These vortices intertwine and move continuously, causing the Aconitum carmichaelii to tumble, collide, and rub against each other throughout the process from the feed hopper to the discharge hopper, ultimately resulting in the peeling of the outer skin.

[0021] 2. This peeling machine assembly adopts a three-roller, two-channel structure, which has the advantages of compact structure, reasonable layout, and higher production efficiency. Attached Figure Description
