[0002] In the field of pasta forming technology, the shapes of shaped rice and flour products are diverse. In recent years, the quick-frozen food industry has flourished, and quick-frozen rice and flour products are becoming more and more popular among consumers. Among the quick-frozen rice and flour products, rice and flour products with different shapes are also more popular with family consumption, such as peach shape, rabbit shape, star shape, heart shape or walnut shape, etc. At present, rice and flour products with different shapes need to be shaped manually, such as lifting the dough or manually scratching it, which requires high skills of employees and is highly dependent on experienced employees. In addition, this operation mode requires a large amount of labor, has inconsistent appearance, unstable quality, and low production efficiency. Therefore, how to abolish artificial shaping, how to make the appearance more uniform and stable, and how to improve production efficiency have become important goals in the industry.

[0003] Taking the existing production of longevity peach pastries as an example, it can only be operated manually through single molding, with a low degree of automation and the production process requires multiple people to work, which is inefficient and has high production costs. In addition, there is no fixed unified mold for the molding of some longevity peach-shaped pastries on the market. It is not easy to demold the mold manually, and the quality of the pastries produced is uneven, affecting the quality of the pastries. Furthermore, even if the machine is equipped with a molding mold, different rice and flour products have different shapes, and it is necessary to achieve multiple uses of one machine, and the continuity of the machine's production work is poor, and the production efficiency is low. This case came into being. Utility Model Content

[0020] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments.

[0021] Combination Figure 1 , Figure 2As shown, the utility model discloses a multi-purpose negative pressure adsorption pastry shaping device, which includes a conveyor belt 2 for conveying dough on a support frame 1, a sensor 31, an encoder 32, a visual positioning mechanism 33, and at least two groups of linear modules 4 that can move forward and backward and left and right to form at least two workstations on the support frame 1, and the linear module 4 is located above the conveyor belt 2. In this embodiment, an upper cover plate 11 is supported on the support frame 1, and the visual positioning mechanism 33 and the linear module 4 are located on the upper cover plate 11. The lower end of each linear module 4 is also connected to a liftable cylinder 5, and the movable end of the cylinder is respectively connected to an adsorption shaping mold 6, and the adsorption shaping mold is respectively connected to a negative pressure system (not shown in the figure). Let the conveying motor (not shown in the figure) that drives the conveyor belt 2, the sensor 31, the encoder 32, the visual positioning mechanism 33, the linear module 4, the cylinder 5 and the negative pressure system be respectively connected to a central control system, and the central control system in this embodiment is a power distribution control cabinet 7. When working, the dough to be formed (not shown in the figure) is placed on the conveyor belt 2. The sensor 31 counts the dough passing through the front end of the conveyor belt 2 and then matches the dough sequence and the workstation of the linear module. The linear module 4 waits at a fixed distance, and then the central control system sends a signal to the encoder 32 to start measuring the distance of the dough in the corresponding sequence. The encoder 32 calculates the triggering action time of the linear module 4 at the corresponding workstation based on the distance between the dough and the linear module, the conveying speed of the conveyor belt, and the downward movement speed of the linear module (this part can be implemented according to the control program and will not be described in detail here), to ensure that the corresponding adsorption and shaping mold 6 can accurately move on the dough when the corresponding dough arrives and synchronously follow the negative pressure adsorption molding. The visual positioning mechanism 3 can take a photo of the dough on the conveyor belt 2 and then locate the dough coordinates and transmit the information to the central control system. The central control system drives and controls each linear module 4 to adjust the position according to the coordinate information, and then drives the cylinder 5 to press down according to the required trigger action time when the time is reached. At this time, the dough just arrives under the adsorption shaping mold to follow the dough, so that the adsorption shaping mold 6 just buckles on the dough, thereby adsorbing and shaping the dough, and lifts up after the dough is adsorbed and followed. The adsorption shaping mold continues to move forward during adsorption shaping, and the speed is consistent with the conveyor belt speed to achieve follow-up shaping (adsorption can be completed in a short time), and is lifted up after the dough is adsorbed and followed, and the action is repeated later.

[0022] Specifically, the sensor 31 is located at the front end of the conveyor belt, and the sensor sensing can be completed by an optical fiber beam sensor. The visual positioning mechanism 33 can be set on the upper cover plate 11 of the support frame 1 and located above the front end of the conveyor belt. It can include a visual lens and a visual light. The visual lens can continuously take pictures to calibrate the coordinate position of the dough after the dough enters the conveyor belt, and transmit the coordinate position signal to the central control system. The central control system can drive the corresponding linear module to adjust the position and then act. In the visual positioning mechanism, the visual lens can take pictures of the dough and transmit the pictures to the central control system of the machine. The central control system uses visual photography to locate and record the coordinates of the dough. The sensor will record the odd and even numbers of dough passing through (such as two linear modules) or the arrangement positions (when there are more than two linear modules). The central control system can send a signal to the encoder to start recording the distance traveled by the dough in the corresponding position, and use the encoder to measure the distance to calculate the driving time. The corresponding linear module can adjust the position according to the position of the dough, and then the cylinder 5 under the corresponding linear module 4 starts to act according to the distance of the dough, and presses down with the adsorption molding mold 6 to follow the shape.

[0023] In this embodiment, two sets of linear modules 4 are provided on the support frame 1 to form a double station. The visual lens can take a picture of the dough on the conveyor belt 2 to locate the dough coordinates and record the odd and even numbers of the dough. One linear module acts on the odd-numbered dough, and the other linear module acts on the even-numbered dough. Figure 2 As shown, each linear module 4 includes a forward and backward moving module 41 that can move forward and backward synchronously above the conveyor belt 2 in parallel. A longitudinal guide rail 42 (screw) parallel to the conveyor belt can be provided at the bottom of the upper cover plate 11 of the support frame. The forward and backward moving module 41 moves forward and backward on the longitudinal guide rail 41. The forward and backward moving module 41 is connected to a forward and backward moving motor 43. The forward and backward moving motor 43 can drive the forward and backward moving module to move forward and backward. At the same time, a left and right moving module 44 that can move left and right is installed at the bottom of the forward and backward moving module 41. The left and right moving module 44 is connected to a left and right moving motor 45 that can drive it to move left and right. The left and right moving module 44 can be installed on a transverse guide rail 46. The forward and backward moving motor 43 and the left and right moving motor 45 are both servo motors. The forward and backward moving motor 43 and the left and right moving motor 45 are respectively electrically connected to the central control system and receive movement instructions from the central control system.

[0024] Combination Figure 3 , Figure 4As shown, the adsorption shaping mold 6 may include a cavity 62 formed inwardly at the bottom of a mold body 61 to form a corresponding shape of the pastry to be formed. The cavity can be a peach shape, a rabbit shape, a heart shape, etc., so that the dough can be shaped into the shape corresponding to the cavity through adsorption. When it is necessary to produce pastry products of different shapes, it is only necessary to directly replace the adsorption shaping mold 6 to achieve multiple uses of one machine. A negative pressure port 63 is provided at the top of the cavity 62, and the negative pressure port 63 is externally connected to the negative pressure system to realize negative pressure suction and pulse backblowing. In this embodiment, the mold body is directly formed in one piece, and the negative pressure port is connected to the negative pressure cavity 64. The negative pressure cavity 64 can be connected to the negative pressure pipeline of the negative pressure system through a pipe joint 65 (not shown in the figure), and the negative pressure system is provided with a solenoid valve that can control the opening and closing of the negative pressure pipeline. When there is an indentation in the dough to be formed, such as a longevity peach-shaped bun, a pressure strip 66 can be convexly provided in the cavity 62.

[0025] Furthermore, a plurality of negative pressure ports 63 may be provided on the peripheral wall of the cavity 62, and the other end of each negative pressure port 63 is connected to the negative pressure cavity 64 to realize negative pressure suction and pulse backflush. The negative pressure port 63 may be connected to the negative pressure cavity 64 through a connecting channel 631 provided in the mold body 61. The plurality of negative pressure ports are distributed in the cavity 62, which can make the adsorption shaping process more stable, perform actions in multiple directions, make the dough surface smoother, avoid defects, and be more efficient.

[0026] The adsorption molding time of the adsorption molding mold 6 is set to 0.2-08s, the negative pressure adjustment range is 0.4-08MPa, and the volume range of the cavity is 500-800cm 3 . For dough that does not rebound, negative pressure suction is used in the cavity to make the dough adsorbed to the inner surface of the cavity for molding, so that the dough can be lifted and shaped directly, and the dough can be demolded directly after the adsorption is completed, with good molding effect and high efficiency. When demolding, since the inner wall of the cavity is smooth and non-stick, the dough can be demolded easily and completely by directly using the pulse backblowing method. Among them, the pulse backblowing time is 0.1s, and the gas can be backblown inward at a pressure of 1-5 kg.

[0027] When the utility model is used, the production and processing of longevity peach buns is taken as an example for explanation, and the specific situation is as follows:

[0028] The adsorption shaping mold used was replaced with a peach-shaped mold, and the mold cavity volume was 800cm 3, the adsorption shaping time is 0.6s, and the negative pressure value is 0.5MPa. There are two linear modules in the device, defined as the first station and the second station. The starting position of the adsorption shaping mold of the first station is fixed at 15cm away from the sensor, and the starting position of the adsorption shaping mold of the second station is fixed at 60cm away from the sensor; using visual photography positioning, sensor induction and encoder ranging, when the odd-numbered dough moves to 15cm away from the sensor, the linear module of the first station adjusts its position and presses the cylinder down at the same time, driving the adsorption shaping mold to adsorb and follow the odd-numbered dough to form; when the even-numbered dough moves to 60cm away from the sensor, the linear module of the second station adjusts its position and presses the cylinder down at the same time, driving the adsorption shaping mold to adsorb and follow the odd-numbered dough to form. The two adsorption shaping molds are lifted up after adsorption for 0.3s respectively, and then the action is repeated.

[0029] After adopting the utility model, the following advantages can be achieved:

[0030] 1. It eliminates the need for manual shaping of dough, greatly saving labor costs; 2. Through adsorption shaping, the appearance is more uniform and stable, and the molds can be diversified, such as peach shape, rabbit shape, star shape, heart shape, etc., and the production of different shapes of pastries can be done by simply replacing the mold and changing the control parameters, so one machine can be used for multiple purposes;

[0031] 3. The visual positioning mechanism cooperates with the linear module to ensure that the dough is accurately adsorbed and reduce defective products;

[0032] 4. The servo-driven linear module and adsorption shaping mold are both double-station or multi-station, which greatly improves the efficiency and can reach 70-90 pellets / minute.

[0033] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present utility model.
