Description

Technical Field

[0001] This utility model belongs to the field of food processing machinery technology, and in particular relates to a roller pressing device with adjustable dough thickness. Background Technology

[0002] In the pasta processing industry (such as noodles and dumpling wrappers), dough rolling is one of the key processes. In traditional equipment, the distance between the two rollers (i.e., the dough thickness) is mostly adjusted manually. This adjustment process is time-consuming and labor-intensive, and the accuracy is difficult to guarantee, failing to meet the high requirements of modern food processing for product consistency and production efficiency. Manual adjustment also makes it difficult to quickly switch between different dough thicknesses during production. Furthermore, existing electric dough rolling devices have poor stability and cannot guarantee stable adjustment of dough thickness. Utility Model Content

[0003] In order to overcome the shortcomings of existing technologies, the purpose of this utility model is to propose a roller pressing device with adjustable dough thickness, which is designed with an automated thickness adjustment mechanism to achieve multi-level, precise and automatic control of dough thickness.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rolling device with adjustable dough thickness, comprising: a frame, a first dough roller and a second dough roller arranged in parallel, and a drive mechanism for driving the first dough roller and the second dough roller to rotate synchronously.

[0005] The first dough roller is mounted on the frame; the second dough roller is slidably mounted on the frame via a roller seat; the frame is provided with a thickness adjustment mechanism for driving the roller seat to move;

[0006] The thickness adjustment mechanism includes a power source, an adjustment output gear driven by the power source, an adjustment driven gear meshing with the adjustment output gear, and an adjustment gear shaft coaxially arranged with the adjustment driven gear; the adjustment gear shaft is provided with a threaded portion, and the threaded portion and a nut fixed to the roller seat form a threaded pair; at least one level stop assembly for limiting the movement position of the roller seat is also provided on the frame.

[0007] Furthermore, roller seats are provided at both ends of the second face roller, and driven gears and gear shafts of the thickness adjustment mechanism are provided on both roller seats. The two driven gears mesh with the same adjustment output gear.

[0008] The two ends of the second skin roller are mounted on the roller seat via bearings, and the roller seat is slidably mounted on the guide rail of the frame.

[0009] Furthermore, the stopping assembly includes at least one stopping cylinder, the piston rod of which adjusts the output gear in opposite directions.

[0010] Furthermore, the power source is an electric motor or a rotary cylinder.

[0011] Furthermore, both the first and second dough rollers are composite structures, with an inner support layer and an outer food-grade stainless steel layer.

[0012] Furthermore, the inner support layer is a roller frame made of steel or aluminum alloy.

[0013] Furthermore, the drive mechanism for driving the first and second leather rollers to rotate synchronously includes: a drive motor, a drive gear, and a driven gear; the drive motor is connected to the drive gear and drives the drive gear to rotate; the drive gear and the driven gear mesh with each other, and the drive gear drives the driven gear to rotate synchronously; the drive gear is connected to the rotating shaft of the first leather roller, and the driven gear is connected to the rotating shaft of the second leather roller.

[0014] Furthermore, the tooth lengths of the driving gear and the driven gear are greater than the distance the roller seat moves.

[0015] The beneficial effects of adopting this technical solution are:

[0016] Automatic and precise adjustment: Driven by a motor or rotary cylinder, combined with gear and threaded transmission, the thickness of the dough is automatically adjusted. The adjustment process is smooth and precise, avoiding human error.

[0017] Multi-level adjustable thickness: By setting up multi-stage stop cylinders, multiple different sheet thickness levels can be preset. During production, simply controlling the action of the corresponding stop cylinder allows for quick and accurate switching to the target thickness, greatly improving production flexibility and efficiency.

[0018] Stable and reliable structure: The thickness adjustment mechanism is symmetrically arranged at both ends of the roller, which ensures the synchronicity and uniformity of the roller gap adjustment and ensures the stability of the dough pressing quality.

[0019] Reduced costs and processing difficulty: The dough roller adopts a composite structure, with only the outer layer using expensive food-grade stainless steel and the inner layer using ordinary metal, which significantly saves material costs and reduces the overall processing difficulty.

[0024] To make the purpose, technical solution and advantages of this utility model clearer, the present utility model will be further described below with reference to the accompanying drawings.

[0025] In this embodiment, see Figure 1 - Figure 3 As shown, a rolling device with adjustable dough thickness includes: a frame, a first dough roller 1 and a second dough roller 2 arranged in parallel, and a drive mechanism for driving the first dough roller 1 and the second dough roller 2 to rotate synchronously.

[0026] The first dough roller 1 is mounted on the frame; the second dough roller 2 is slidably mounted on the frame via a roller seat 3; the frame is provided with a thickness adjustment mechanism for driving the roller seat 3 to move;

[0027] The thickness adjustment mechanism includes a power source 4, an adjustment output gear 5 driven by the power source 4, an adjustment driven gear 6 meshing with the adjustment output gear 5, and an adjustment gear shaft 7 coaxially arranged with the adjustment driven gear 6; the adjustment gear shaft 7 is provided with a threaded part, and the threaded part and a nut fixed to the roller seat 3 form a threaded pair; at least one first-stage stop assembly 8 for limiting the movement position of the roller seat 3 is also provided on the frame.

[0028] As an optimization of the above embodiments, such as Figure 1 - Figure 3 As shown, roller seats 3 are provided at both ends of the second face roller 2, and driven gears and gear shafts of the thickness adjustment mechanism are provided on both roller seats 3. The two driven gears mesh with the same adjustment output gear 5.

[0029] The two ends of the second face roller 2 are mounted on the roller seat 3 by bearings, and the roller seat 3 is slidably mounted on the guide rail of the frame.

[0030] When the thickness of the dough needs to be adjusted, the rotary cylinder is activated. The rotary cylinder drives the adjusting output gear 5 to rotate, which in turn drives the driven gear 11 and the gear shaft to rotate. Since the nut is fixed, the gear shaft will move axially while rotating. This axial movement directly pushes or pulls the roller seat 3, causing the second dough roller 2 to move closer to or further away from the first dough roller 1, thereby changing the roller gap.

[0031] The thickness adjustment mechanism is the core of this invention for achieving precise control, and its working process is a precise conversion of "rotational motion → linear motion".

[0032] Power start-up: After the operator issues the thickness adjustment command, the power source 4 motor or rotary cylinder starts to work.

[0033] Motion transmission: Power source 4 drives and adjusts the output gear 5 to rotate.

[0034] Gear transmission: Adjusting the output gear 5 drives the driven gear meshing with it to rotate. This stage of transmission usually has the effect of speed reduction and torque increase, making subsequent movements smoother and more powerful.

[0035] Motion conversion: The driven gear is fixedly connected to the gear shaft, driving the gear shaft to rotate together. The gear shaft has a threaded part machined on it, which, together with a nut fixedly mounted on the frame, forms a threaded pair.

[0036] Core action: Because the nut is fixed, according to the principle of thread transmission, the rotating gear shaft, under the constraint of the nut, converts its rotational motion into precise linear motion along its axis.

[0037] Adjustment: The linear motion of the gear shaft directly pushes or pulls the roller seat 3 connected to it, causing the second skin roller 2 to move closer to or further away from the fixed first skin roller 1, thereby steplessly and continuously changing the roller gap.

[0038] As an optimization of the above embodiments, such as Figure 3 As shown, in order to achieve rapid and accurate positioning of different thicknesses, the stop assembly 8 includes at least one stop cylinder. The piston rod of the stop cylinder is directed towards the adjusting output gear 5. When the piston rod of the stop cylinder extends, it blocks the rotation of the adjusting output gear 5, thereby limiting the movement of the roller seat 3 and fixing the moving position of the roller seat 3.

[0039] Multiple stop cylinders are installed on the frame. Figure 2 Two are shown. When the roller seat 3 moves to a preset position, the piston rod of the corresponding stop cylinder extends, preventing the roller seat 3 from moving forward, thereby precisely positioning the roll gap at the preset thickness value. For example, the first-stage stop cylinder extends to correspond to the thickest sheet, the second-stage stop cylinder extends to correspond to the thinner sheet, and so on.

[0040] Working principle of multi-level thickness positioning and stopping mechanism:

[0041] Preset positions: Several stop cylinders are pre-installed on the frame, and the extension position of each cylinder corresponds to a preset skin thickness value such as 1.0mm, 1.5mm, 2.0mm.

[0042] Positioning process: When the thickness adjustment mechanism drives the roller seat 3 to move in the direction of "reducing the roller gap", the roller seat 3 will pass through the positions of each stop cylinder in sequence.

[0043] Mechanical limit: If a 1.5mm thick dough sheet is required, the control system extends the corresponding stop cylinder piston rod. When the roller seat 3 moves to this position, its side is mechanically blocked by the extended piston rod, immediately stopping its movement.

[0044] Precision assurance: This rigid mechanical limiting method avoids the errors and drift that may exist in purely electrical or software positioning, ensuring extremely high repeatability of positioning for each adjustment, thereby guaranteeing the consistency of the skin thickness.

[0045] As an optimized solution of the above embodiments, both the first dough roller 1 and the second dough roller 2 are composite structures, with an inner support layer and an outer food-grade stainless steel layer.

[0046] Preferably, the inner support layer is a roller frame made of steel or aluminum alloy, which provides the main structural strength and rigidity required for rolling, and is low in cost and easy to process into the required shape.

[0047] Food-grade stainless steel outer layer: tightly wrapped around the outer surface of the inner layer, serving as the working surface that comes into contact with food, fully meeting hygiene and safety standards.

[0048] This structure minimizes the use of high-cost stainless steel while ensuring food safety, significantly reducing material costs and overall processing difficulty.

[0049] As an optimization of the above embodiments, such as Figure 1 - Figure 2 As shown, the driving mechanism for synchronously rotating the first leather roller 1 and the second leather roller 2 includes: a drive motor 9, a drive gear 10, and a driven gear 11; the drive motor 9 is connected to the drive gear 10 and drives the drive gear 10 to rotate; the drive gear 10 and the driven gear 11 mesh with each other, and the drive gear 10 drives the driven gear 11 to rotate synchronously; the drive gear 10 is connected to the rotating shaft of the first leather roller 1, and the driven gear 11 is connected to the rotating shaft of the second leather roller 2.

[0050] The drive motor 9 drives the first dough roller 1 and the second dough roller 2 to rotate in opposite directions via gears. The stirred and matured dough falls from above between the two rollers and is pressed into dough sheets.

[0051] The tooth lengths of the driving gear 10 and the driven gear are greater than the distance the roller seat 3 moves.

[0052] To better understand this utility model, the working principle of this utility model will be described in detail below:

[0053] Feeding and initial pressing: The mixed and matured dough falls from the upper feed port into the roller gap between the fixed first dough roller 1 and the adjustable second dough roller 2.

[0054] Roll forming: Driven by a motor, two rollers rotate in opposite directions, rolling the dough into a continuous dough belt of initial thickness.

[0055] Thickness adjustment preparation: When it is necessary to change the thickness of the dough, the thickness adjustment mechanism is activated.

[0056] Precise gap adjustment: The adjustment mechanism drives the second face roller 2 and its roller seat 3 to move smoothly, changing the gap between the two rollers.

[0057] Thickness positioning and locking: When the roller seat 3 moves to the preset position, it is mechanically blocked and positioned by the stop component 8, thereby precisely locking the roller gap at the new set value.

[0058] Continuous output and post-processing: After adjustment, the device continues to press out dough sheets of the new thickness and conveys them to the downstream roller cutter device for cutting into strips or forming.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
