Description

Technical Field

[0001] This utility model relates to the field of food processing machinery technology, and in particular to a feeding and unloading device for the pickling process. Background Technology

[0002] In the traditional pickling process, transferring the vegetables from one vat to another clean vat after pickling is complete is the core step. Currently, this step mainly relies on manual labor: operators need to manually lift the vats, which weigh tens of kilograms, to a high position, then tilt the vat to pour out the vegetables, and finally replace the empty vat.

[0003] The following problems exist: 1. Labor intensity and safety risks: Manual handling of heavy cylinders can easily lead to muscle strain, and the splashing of pickling liquid during tilting makes the working environment slippery, posing significant safety hazards; 2. Efficiency bottleneck: A single tilting of the cylinder takes as long as 5-8 minutes, which is difficult to match the pace of modern continuous production lines; 3. The existing simple lifting device can only achieve vertical lifting, and the tilting action still requires manual assistance, and it lacks key functions such as cylinder positioning and flexible protection.

[0007] As a preferred technical solution of this utility model, the feeding baffle includes: a U-shaped bracket with a waist-shaped hole at the bottom and adjustablely fixed to the side edge of the clamping base plate by bolts; a semi-circular bracket welded to the top of the U-shaped bracket, the inner arc radius of which is 5-10mm larger than the standard outer diameter of the vegetable crock; and an elastic buffer plate, which is detachably embedded in the inner wall of the semi-circular bracket by a buckle, and the thickness of the elastic buffer plate increases from top to bottom in the vertical direction.

The clamping mechanism automatically locks the cylinder body through symmetrical pneumatic grippers (semi-circular fixed clamp + movable clamp), and lifts it off the ground with the lifting cylinder, avoiding manual handling.

[0015] 2. The gradually thickened elastic buffer plate of the feeding baffle (thin upper and thick lower structure) absorbs the tipping impact force and reduces the risk of cylinder breakage. At the same time, the 5-10mm gap design is compatible with cylinder diameter tolerances. The 2-5mm deep anti-slip texture of the semi-circular movable clamp and the replaceable rubber layer of the fixed clamp achieve high torque gripping and avoid scratching the cylinder wall. The T-shaped guide rail and the lifting limit block / elastic buffer work together to ensure the positioning accuracy of ±2mm of the cylinder lifting stroke.

[0016] 3. The limit switch provides dual-point control (stop lifting at the highest position / stop lowering at the lowest position) to prevent equipment damage caused by misoperation. The entire process is non-contact and meets food hygiene control requirements. Attached Figure Description

[0026] like Figure 1-5 As shown, this utility model provides a feeding and unloading device for the pickling vat turning process. The core structure of this feeding and unloading device for the pickling vat turning process includes:

[0027] Base 1: It adopts a welded frame of channel steel, with anchor bolt mounting holes at the bottom to support the entire equipment.

Lifting Cylinder 22: The cylinder body is hinged to the rear side of the base 1, and the output end is connected to the crossbeam of the tilting frame 23 via a double-row roller chain. Tilting Frame 23: A rectangular frame welded from square steel, with 6 guide wheels at the four corners that cooperate with the L-shaped lifting tracks 21, and the wheel groove gap ≤0.5mm. Limit Switch 24: The first switch 241 is fixed at the top of the vertical track, and the second switch 242 is fixed 40cm above the bottom of the vertical track, connected to the controller 221 via a shielded cable.

[0029] Feeding Mechanism 3: Clamping Base Plate 31: 200×300×20mm steel plate, bolted to the right side of the tilting frame 23. Supporting Base Plate 32 and Feeding Baffle 33: welded to the upper surface of the clamping base plate 31, baffle height 300mm. Sliding Guide Rail 34: two T-shaped guide rails 341 are fixed parallel to each other on the left side of the tilting frame 23, guide rail length 300mm.

[0031] The elastic buffer plate 333 of the feeding baffle 33 is made of EPDM rubber and is embedded in the inner wall of the semi-circular bracket 332 by snap-fit. It features a thickness gradient design: 5mm thick at the top, 10mm in the middle, and 15mm at the bottom, capable of absorbing impact forces of ≥200N during tipping.

[0035] 3. Reset and unloading stage: The hydraulic cylinder 22 retracts to make the tilting frame 23 return to the vertical track; when the second switch 242 is triggered, it stops at the initial position; the lifting cylinder 35 descends to make the cylinder body touch the ground, and the telescopic cylinder 44 opens the movable clamp 43 to release the empty cylinder.

[0036] This invention relates to a loading and unloading device for the pickling vat turning process. It achieves integrated lifting and tilting of the vats through a unique L-shaped track and hydraulic cylinder combination, and rigidly integrates the loading mechanism into the motion unit, ensuring the accuracy and coordination of the vat position throughout the entire process. The finely designed flexible positioning baffle, buffer structure, clamping device with compensation mechanism, and reliable multi-level limiting and buffering together constitute an efficient, stable, and safe automated pickling vat turning and loading / unloading solution, significantly reducing manual labor intensity and improving production efficiency.
