Abstract
Description
Technical Field
[0001] This utility model relates to the field of pasta processing equipment technology, specifically to a fully automatic hydraulically driven dough sheet pressing and forming equipment. Background Technology
[0002] The fully automatic hydraulically driven dough pressing and forming equipment is an automated device that uses hydraulic pressure to press irregular dough (such as scraps cut from bread production) into regular shapes (such as squares). Its core function is to replace traditional manual kneading or semi-mechanized processing, realizing fully unmanned operation from dough input, pressing to forming output, thereby improving dough recycling rate and forming quality.
[0003] However, existing pressing equipment for recycling loose dough still has significant drawbacks: on the one hand, traditional manual dough presses rely on manual operation, requiring the dough to be manually kneaded and loosened before being fed into the pressing equipment, which is time-consuming and labor-intensive; on the other hand, existing dough sheeters and puff pastry machines can only stretch or fold the dough, unable to directly press loose dough into a regular shape in one go, resulting in the dough needing to be transferred through multiple machines, making the process cumbersome. Furthermore, repeated manual kneading or multiple processing steps by semi-mechanized equipment can easily cause the dough temperature to rise, leading to premature fermentation and seriously affecting the quality stability of bread products. Therefore, there is an urgent need for a fully automatic, high-precision dough pressing and shaping device that can avoid temperature rise and fermentation to solve the above-mentioned technical problems. Utility Model Content
[0004] The purpose of this utility model is to provide a fully automatic hydraulically driven dough pressing and forming equipment. Through hydraulic system drive, mold cavity forming and automatic control design, it can achieve efficient and regular pressing and forming of scattered dough, while avoiding fermentation problems caused by dough temperature rise. It solves the defects of existing technology such as inefficient manual operation, cumbersome multi-equipment transfer and the impact of temperature rise on quality.
[0005] The technical solution provided by this utility model is a fully automatic hydraulically driven dough pressing and forming equipment, including a cabinet. The bottom of the cabinet is equipped with a hydraulic oil tank and a compressor, and the top of the cabinet is equipped with a mold cavity. A sealing cover is rotatably connected to one side of the mold cavity on the top of the cabinet. The mold cavity is composed of a mold frame made of stainless steel and a pressing plate made of stainless steel at the bottom. The bottom of the pressing plate is connected to a hydraulic cylinder that is connected to the hydraulic oil tank and the compressor.
[0006] As a preferred embodiment of this utility model, one side of the sealing cover is fastened and sealed to the top of the cabinet by a rotating lock, and the sealing cover is provided with an auxiliary handle.
[0007] As a preferred embodiment of this utility model, an induction switch is provided on the top of the cabinet on one side of the sealing cover.
[0008] As a preferred technical solution of this utility model, the cabinet is provided with a partition for fixing the hydraulic cylinder, and the hydraulic cylinder is set vertically.
[0009] As a preferred embodiment of this utility model, the bottom of the pressing plate is connected to the output end of the hydraulic cylinder through a lifting plate, and the four corners of the bottom of the pressing plate are fixedly connected to the lifting plate through support rods.
[0010] As a preferred technical solution of this utility model, guide rods are provided at the four corners of the outer side of the mold inside the cabinet, and a limiting sleeve is provided at the guide rod of the lifting plate. A spring is sleeved on the outer side of the guide rod between the limiting sleeve and the cabinet.
[0011] As a preferred embodiment of this utility model, the mold frame is either rectangular or circular, and the shape of the pressing plate matches the inner side of the mold frame.
[0012] The advantages of this utility model compared with the prior art are as follows:
[0013] 1. Fully automated operation: The hydraulic cylinder is automatically started by triggering the induction switch when the sealing cover is closed, realizing the unmanned operation of the entire process of "dough input-pressing-forming output", which significantly reduces labor costs and improves production efficiency (3-5 times more efficient than traditional manual operation).
[0014] 2. High-precision forming: The hydraulic cylinder drives the pressing plate to press vertically upward (pressure range 10-50MPa adjustable). Combined with the regular inner shape of the stainless steel mold frame, scattered dough pieces can be pressed into regular dough pieces such as squares and circles in one go, solving the problem that traditional equipment cannot directly form dough pieces. The forming quality is stable (dimensional error ≤0.5mm).
[0015] 3. Anti-temperature rise design: The efficient drive of the hydraulic system shortens the pressing time (single pressing time ≤ 15 seconds), and the mold cavity is isolated from the hydraulic oil tank and compressor by the partition frame to reduce external heat transfer and prevent the dough from rising and fermenting due to repeated processing or prolonged heating, thus ensuring the quality of bread products.
[0016] 4. Strong structural stability: The coordinated design of the lifting plate, support rod, guide rod and spring ensures the verticality and stability of the pressing plate during lifting, reduces equipment vibration loss and extends service life (critical component life ≥ 100,000 cycles).
[0017] 5. High flexibility: The mold frame can be replaced with various shapes such as rectangle or circle to adapt to the dough requirements of different bread products and improve the versatility of the equipment. Attached Figure Description

[0028] In this utility model, the cabinet 1 is provided with a partition frame 12 for fixing the hydraulic cylinder 8. The hydraulic cylinder 8 is vertically arranged. While fixing the hydraulic cylinder 8, the upper mold cavity 4 area can be separated from the lower hydraulic oil tank 2 and compressor 3 to prevent oil contamination below and flour contamination above.
[0029] Working principle
[0030] 1. Power drive: The hydraulic oil tank 2 provides high-pressure oil, the compressor 3 regulates the oil pressure, and the hydraulic cylinder 8, as the actuator, converts hydraulic energy into mechanical energy, driving the pressing plate 7 to move vertically, thereby pressing the loose dough.
[0031] 2. Automated control: The closing action of the sealing cover 5 is triggered by the induction switch 11 to start the hydraulic system, realizing an automated process without human intervention and avoiding human operation errors.
[0032] 3. Structural stability assurance: The separator 12 isolates the hydraulic system from the mold cavity 4 area to prevent oil contamination below and flour contamination above; the guide rod 15 and the limiting sleeve 16 limit the lateral displacement of the lifting plate 13, and the spring 17 provides buffering during the pressing process to reduce the impact load damage to the equipment and ensure the verticality and stability of the lifting of the pressing plate 7.
[0033] 4. Forming precision control: The matching design of the regular inner shape (such as rectangle) of the stainless steel mold frame 6 and the pressing plate 7, combined with the adjustable pressure of the hydraulic system (10-50MPa), ensures that the dough is evenly stressed during the pressing process, forming regular dough blocks of consistent size.
[0034] 5. Anti-temperature rise mechanism: The efficient drive of the hydraulic system shortens the pressing time (≤15 seconds per cycle), reducing the heat accumulation of the dough due to prolonged pressure or friction; the isolation design of the separator 12 reduces the heat transfer from the hydraulic oil tank 2 and compressor 3 to the mold cavity 4, avoiding premature fermentation caused by dough temperature rise.
