Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of dough skin production, and particularly relates to a dough skin production line. BACKGROUND

[0002] As a key equipment for automatic production of dough skin, the dough skin production line needs to complete a series of processes such as conveying, processing and forming of dough skin in actual operation. Its automatic operation mode should improve production efficiency and ensure product quality stability, but in the actual production process, the automatic equipment of the production line still faces many problems affecting product quality and production efficiency, which become important factors restricting production effect.

[0003] In terms of product quality, the deficiencies of the dough skin production line mainly lie in two core links: one is the edge cutting link, due to the limitations of equipment design and control mode, sawteeth and indentation deviation are prone to occur, which directly leads to poor regularity of dough skin appearance, and does not meet the appearance standard of high-quality products; the other is the humidity control link, local over-drying or over-wetting of dough skin is prone to occur in production, such humidity unevenness not only destroys the ductility of dough skin (over-drying is prone to breakage, and over-wetting is prone to adhesion), but also has adverse effects on the taste of finished products, and reduces product quality.

[0004] In terms of production efficiency and cost control, the precision control ability of the existing dough skin production line is insufficient. This deficiency makes the pass rate of products fluctuate greatly in the production process, and part of batches need to be screened, reworked or even scrapped due to unqualified quality, which not only wastes raw materials and working hours, but also increases production cost. However, the existing dough skin production line lacks effective targeted solutions to the above-mentioned edge cutting quality, humidity control and pass rate fluctuation problems, therefore, it is necessary to improve the production line to solve these technical problems. SUMMARY

[0005] The application aims to solve the technical problems that sawteeth and indentation deviation are prone to occur in edge cutting, and dough skin is prone to local over-drying or over-wetting, which affect product quality.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0035] The following description is made in connection with Figures 1 to 6 Further details of the application are described below,

[0036] The dough production line disclosed by the embodiments of the application comprises a rack 1, a conveying mechanism 2 arranged on the rack 1, a humidity control device and a trimming device.

[0037] The conveying mechanism 2 comprises two mounting panels A202 arranged on both sides of the rack 1 and provided with straight notches A201, a roller frame 203 fixed between the two mounting panels A202 by bolts and nuts penetrating through the straight notches A201, and a plurality of conveying rollers 204 arranged on the roller frame 203 and used for conveying dough. The roller frame 203 is provided with an operation space 205 for subsequent operation of related components, so as to ensure that the devices can smoothly work on the dough being conveyed. The roller frame 203 is fixed by bolts and nuts penetrating through the straight notches A201, and the installation height and the inclination angle of the roller frame 203 can be adjusted, so as to facilitate feeding of the dough into the dough pressing wheel 12.

[0038] The humidity control device is used to solve the problem of local over-drying or over-wetting of the dough, and comprises a multi-sensor array 3, a blowing device 4 and a humidifying device 5.

[0039] The multi-sensor array 3 is arranged below the conveying mechanism 2 and is used to monitor the dough humidity and flow rate in real time. The array comprises at least two dough sensors, and the dough sensors are arranged on a support rod 301 fixedly arranged on the rack 1 and are arranged in mounting seats 302 arranged at the end of the support rod 301. The multi-sensor array 3 monitors the surface and internal humidity of the dough in real time based on resistance value feedback, so as to provide accurate basis for subsequent humidity adjustment.

[0040] The blowing device 4 is used to blow dry air flow to the local area of the dough that is over-wetted. The blowing device 4 comprises a gas pump, a gas pipe 401, a gas nozzle 402 and an air flow adjusting valve, the gas outlet of the gas pump is connected to the inlet of the air flow adjusting valve through a pipeline, the outlet of the air flow adjusting valve is connected to one end of the gas pipe 401, and the other end of the gas pipe 401 is connected to the gas nozzle 402. The gas nozzle 402 is arranged below the roller frame 203 and is fixed on a rotating shaft 404 rotatably connected between the rack 1 through a connecting seat 403, the rotating shaft 404 is driven to rotate by a motor arranged on the rack 1, so as to adjust the angle of the gas nozzle 402. The PID algorithm is used to control the blowing intensity and the angle, so as to realize humidity gradient compensation.

[0041] The humidifying device 5 is used to spray water mist to the local area of the dough sheet that is too dry. It includes a water supply pipeline 501 connecting the water storage bucket 502 and the water spraying head 503, a water quantity control valve installed on the water supply pipeline 501, and a water level sensor installed in the water storage bucket 502. The water spraying head 503 is an atomizing nozzle or an ultrasonic atomizer. The water storage bucket 502 is fixedly installed on the top of a vertical support rod 506, which is fixedly installed on the rack 1. The water spraying head 503 is fixed on a clamping seat 504, which is installed on the longitudinal support rod 505 through locking bolts, so that the position of the clamping seat 504 on the longitudinal support rod 505 can be adjusted. The spray opening of the water spraying head 503 faces the automatic belt conveying line B11. Two vertical supports 13 are arranged on the rack 1 and located on both sides of the automatic belt conveying line B11. The longitudinal support rod 505 is fixed on the two vertical supports 13.

[0042] The humidity state and flow rate of the dough sheet are monitored in real time by the dough sheet sensor (core component of the multi-sensor array 3) to provide data basis for subsequent adjustment. When the sensor detects that the dough sheet is too dry in a local area, the water spraying head 503 (belonging to the humidifying device 5) of the dough sheet humidifying device 5 sprays water mist to the area to supplement moisture. The multi-sensor array 3 can use the HC2-S3 series humidity sensor of Rotronic, Switzerland, which has high precision and fast response and can be used to monitor the humidity of the dough sheet. For flow rate monitoring, the DFS60B series photoelectric rotary encoder of SICK, Germany, can be used. By being installed on the conveying roller, the rotational speed of the conveying roller is monitored in real time to calculate the flow rate of the dough sheet. The combination of multiple HC2-S3 humidity sensors and DFS60B encoders can form a multi-sensor array.

[0043] When it is detected that the dough sheet is too wet in a local area, the air blowing device 4 (belonging to the air blowing device 4) blows air to the area to accelerate the evaporation of moisture. During the entire adjustment process, the device dynamically adjusts the intensity of water spraying / air blowing according to the flow rate and humidity changes fed back by the sensor to ensure accurate adjustment.

[0044] Through targeted water spraying and air blowing adjustment, the problems of decreased ductility (easy to break) caused by local dryness of the dough sheet or unstable forming (easy to stick) caused by local wetness of the dough sheet are avoided. Based on the dynamic adjustment mode of real-time monitoring, the product quality difference caused by humidity fluctuation is reduced, and the consistency of the finished product taste is improved. Combined with the flow rate monitoring of the dough sheet, the humidification / drying operation is matched with the conveying speed of the dough sheet to avoid adjustment lag or over-adjustment.

[0045] The edge cutting device is used to solve the problems of edge cutting sawteeth and dough sheet deformation, and includes a servo motor 7, a rotating circular knife 6, and an edge material recovery baffle 8.

[0046] The servo motor 7 is used to drive the rotary circular knife 6 to cut. The vertical support 13 is provided with a longitudinal screw linear module 14, and the moving platform 15 of the longitudinal screw linear module 14 is fixedly provided with a mounting plate 16 which is fixedly installed with the servo motor 7. The servo motor 7 cooperates with the dynamic adjustment of the cutting gap to eliminate the sawtooth and reduce the deformation of the dough.

[0047] The servo motor 7 can be selected from the IMS20B series general-purpose AC servo motor of Inovenc. The series motor frame numbers include 40, 60, 80, etc. The power range is 0.05kW-75kW. Various inertia configurations and speed segment configurations are provided. Various encoders such as 17-bit multi-turn absolute value magnetic encoding and 23-bit multi-turn absolute value optical encoding are supported. The driving demand of the rotary circular knife 6 in the dough production line can be met, and accurate position control and speed control can be realized.

[0048] The edge material recovery baffle 8 is fixed at one end of the mounting frame 17 at the top of the rack 1, and is used to block the cut edge material. The blocked edge material is recovered to the dough pulling vehicle and then put into the dough mixer for re-doughing and reuse.

[0049] The dough position and conveying state are monitored by the dough sensor, and the cutting structure (such as the rotary circular knife 6) driven by the servo motor 7 is used for edge cutting operation to ensure that the cutting position is aligned with the edge of the dough.

[0050] The edge material generated by cutting is guided to the dough pulling vehicle by a specific structure (such as a baffle), and then transported to the dough mixer at the initial point of the production line by the dough pulling vehicle, and re-input into the doughing process to realize the recycling of raw materials.

[0051] With the positioning effect of the dough sensor and the stable driving of the servo motor 7, the deviation during edge cutting is reduced, and the problems of sawtooth-shaped edge or indentation deviation easily occurring in traditional cutting are avoided. The edge material is recovered by the dough pulling vehicle and re-input into the dough mixer to realize the secondary use of raw materials, improve the utilization rate of raw materials, and reduce the production cost. The cutting and recovery process does not require manual intervention, matches the automatic conveying rhythm of the production line, and improves the overall production efficiency.

[0052] The rear end of the rack 1 is provided with a full-automatic dough pressing machine 9. The full-automatic dough pressing machine 9 can realize the automatic operation of dough pressing and molding. It can replace manual dough pressing, reduce the error caused by manual intervention, ensure the consistency of the initial molding of the dough, improve the dough pressing efficiency, and better connect with the subsequent automatic devices such as conveying and edge cutting, thereby improving the automatic continuity of the entire production line.

[0053] The rack 1 is provided with an automatic belt conveying line A10 and an automatic belt conveying line B11 on both sides of the conveying mechanism 2; in combination with the material conveying requirement of the production line, the two automatic belt conveying lines can undertake the material conveying function. They can realize accurate conveying of the dough, avoid material accumulation on a single conveying path, and improve the conveying efficiency. At the same time, automatic conveying reduces manual handling, reduces labor cost, and can ensure stable conveying speed and match the operation rhythm of the conveying mechanism 2, the dough pressing wheel 12 and other devices, to ensure that the production process proceeds in an orderly manner.

[0054] The conveying mechanism 2 and the automatic belt conveying line B11 are provided with a dough pressing wheel 12 rotatingly arranged on the rack 1 and used for pressing the dough to a required thickness; the dough pressing wheel 12 can press the passing dough to a required thickness, so that the dough reaches a preset uniform thickness, ensures uniform product specifications, and improves the quality stability of finished products.

[0055] The top of the rack 1 is provided with a support frame 18, and the support frame 18 is provided with a control box 19 for controlling the equipment of the entire production line. From the overall operation control of the production line, the control box 19 can centrally control the operating parameters of each device (such as the sensor of the humidity control device, the blowing / humidifying component, the servo motor 7 of the edge cutting device, etc.). Through unified control, the devices can be cooperated (such as adjusting the edge cutting rhythm according to the conveying speed, adjusting the humidifying / blowing intensity according to the humidity monitoring data), the equipment operation deviation can be corrected in time, the matching failure caused by independent operation of each device can be reduced, and the production precision and product qualification rate can be improved. At the same time, centralized control facilitates real-time monitoring of the production line state by the operator, and simplifies the operation process.

[0056] The dough production line realizes automatic production through the coherent process of "conveying-monitoring-adjusting-processing-recovery": the conveying mechanism 2 conveys the dough by means of the roller frame 203 with adjustable height and angle, to ensure that the dough enters the subsequent process stably; the humidity control device monitors the dough humidity and flow rate in real time through the multi-sensor array 3, and when detecting local dryness / wetness, triggers the humidifying device 5 to spray water mist or the blowing device 4 to blow air flow respectively, to dynamically adjust the humidity; the edge cutting device is driven to rotate by the servo motor 7, and the cutting gap is dynamically adjusted by the sensor positioning, and at the same time, the edge material recovery baffle 8 guides the corner material to the dough pulling vehicle for final recycling and recycling in the dough machine. The whole process is centrally controlled by the control box 19 to ensure the cooperative operation of each device.

[0057] The prior art has obvious short boards in dough quality control, and the production line realizes breakthrough through targeted design: in terms of humidity control, the prior art is difficult to accurately monitor and adjust the dough humidity, which is easy to cause local over-drying / over-wetting, the production line realizes real-time monitoring through sensors and closed-loop adjustment of dynamic water spraying / air blowing, avoids the decrease of ductility or instability of molding caused by humidity problems, and ensures the consistency of finished product taste; in terms of edge quality, the prior art cutting is easy to appear sawtooth and indentation offset, the production line realizes dynamic adjustment of cutting gap through servo motor 7 driving and sensor positioning, eliminates sawtooth and deformation, and improves product appearance regularity.

[0058] The prior art has limitations in production efficiency and cost control, and the production line effectively improves through optimized design: the prior art causes large fluctuation of qualified rate due to lack of precise control, and the corner material recycling rate is low, the production line realizes coordinated operation of each device through control box 19 centralized control, reduces unqualified products caused by equipment cooperation failure, and stabilizes product qualified rate; at the same time, the edge material is recycled through the closed-loop design of the skin car and the dough machine, avoiding raw material waste and reducing production cost; in addition, the automatic conveying, adjusting and recycling process reduces manual intervention, improves overall production efficiency, and solves the problem of manual participation and poor process connection in the prior art.

[0059] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or replace some technical features with equivalent, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application, should be included in the protection scope of the present application.
