DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-8 As shown, the present invention proposes a multi-variable tunnel round steamed bun shaping device, including a rear shell 1, a processing table 2 and a water tank 3. A plurality of guide plates 201 are installed on the top of the processing table 2. The guide plates 201 are provided in three groups, and the three groups of guide plates 201 are arranged in parallel. The three groups of guide plates 201 are respectively installed at the top front end, top rear end and top center of the processing table 2. Two adjacent guide plates 201 in the same group are connected by bolts and nuts, and the tops of the guide plates 201 are all arc-shaped structures. The guide plates 201 are connected by nuts and bolts, so that the longitudinal installation position between the two adjacent guide plates 201 can be adjusted, and the distance between the two adjacent guide plates 201 can also be adjusted, so as to adjust the cross-sectional size and shape of the dough passing position, so as to facilitate the dough to be shaped to different degrees, so that the device has the function of a variable tunnel, thereby adapting to the processing of different steamed buns. The guide plates 201 can be combined with the guide cover to form an S-shaped channel, so that after the dough enters the interior of the device, it passes through the first transmission The dough is pushed by the belt 211, the second transmission belt 212, the first transmission belt 202 and the second transmission belt 210, so that the dough moves horizontally between the guide plate 201, the first transmission belt 211 and the second transmission belt 212. During the horizontal movement, since the guide plate 201 is fixedly installed, the dough rotates while moving horizontally, and the dough is shaped by simulating manual kneading. Several drive motors are fixedly installed inside the processing table 2. The drive motor adopts YE4-100KW type. The drive motors are respectively connected to The first transmission belt 211, the second transmission belt 212, the first conveyor belt 202, and the rollers inside the second conveyor belt 210 are connected, and the drive motor is also connected to the first reversing wheel 208 and the second reversing wheel 209. The drive motor drives the rollers, the first reversing wheel 208 and the second reversing wheel 209 to rotate, so that the first transmission belt 211, the second transmission belt 212, the first conveyor belt 202, and the second conveyor belt 210 rotate respectively, pushing the dough to move inside the device and cooperate with the guide plate 201 to achieve dough shaping; The rear shell 1 is fixedly installed on the top rear side of the processing table 2, and the front shell 101 is fixedly installed on the front of the rear shell 1. The top of the rear shell 1 and the front shell 101 are fixedly installed with a connecting plate 102. The top of the rear shell 1 and the inside of the front shell 101 are fixedly installed with a mounting plate 105, and the bottom of the mounting plate 105 is fixedly installed with a plurality of nozzles 106. The rear shell 1 and the front shell 101 are combined to form a hard protective structure. The plurality of nozzles 106 guide the steam to spray vertically downward to the left and right sides of the front shell 101 and the rear shell 1. The outlet forms an air curtain for protection, and the interior of the front shell 101 and the rear shell 1 is in a positive pressure environment. The combination of the three prevents dust and particulate matter from the external environment from entering the device and coming into contact with the dough, thereby preventing the dough from being contaminated during the shaping process. In addition, the steam sprayed by the nozzle 106 can change the ambient temperature and humidity inside the front shell 101 and the rear shell 1, making the ambient temperature and humidity inside the front shell 101 and the rear shell 1 constant, thereby ensuring that the shaping machine has a good and stable shaping effect on the dough; A water tank 3 is fixedly installed on the top of the connecting plate 102, a cover plate 302 is installed on the top of the water tank 3, a main control box 303 is fixedly installed on the top of the cover plate 302, and the bottom of the main control box 303 extends to the bottom surface of the cover plate 302 and is fixedly installed with a temperature detector and a humidity detector. The water tank 3 can provide a location for installing the surrounding components and can store a certain amount of clean water to generate steam to adjust the ambient temperature and humidity inside the front shell 101 and the rear shell 1. The cover plate 302 can seal the top of the water tank 3 and provide a location for installing the surrounding components. Box 303 can be connected to other electronic components through cables to control the automatic operation of the device. The temperature detector adopts AD592ANZ type and the humidity detector adopts RS495 type. The temperature detector and the humidity detector respectively detect the ambient temperature and ambient humidity inside the water tank 3, and then judge the temperature and concentration of the steam. After the steam reaches the set temperature and concentration, it is conducted to the nozzle 106 through the booster pump 103, and then sprayed into the interior of the front shell 101 and the rear shell 1, so as to regulate the ambient temperature and ambient humidity inside the front shell 101 and the rear shell 1.

[0022] Furthermore, a second conveyor belt 210 is installed at the top of the processing table 2 near the front end, and a second transmission belt 212 is installed at the rear end of the second conveyor belt 210 through a second reversing wheel 209. A first conveyor belt 202 is installed at the top of the processing table 2 near the rear end, and a first transmission belt 211 is installed at the rear end of the first conveyor belt 202. A first reversing wheel 208 is installed on the right side of the top of the processing table 2 for sliding, and the first reversing wheel 208 is located at the center of the second conveyor belt 210 and the first transmission belt 211. The second conveyor belt 210 and the first conveyor belt 202 can respectively apply horizontal thrust to the dough, thereby pushing the dough to move inside the S-shaped channel on the top of the processing table 2, and combining with the guide plate 201 to apply resistance to the dough, kneading the dough to achieve the shaping of the dough. The first conveyor belt 211 and the second conveyor belt 212 can apply horizontal thrust to the front or back side of the dough, so that the dough rotates while moving horizontally and generates friction with the guide plate 201, realizing the effect of simulating manual kneading and shaping the dough.

[0023] Furthermore, a box 205 is fixedly installed at the bottom of the processing table 2, and an electrical box 203 is fixedly installed inside the box 205. Two sets of casters 204 are installed on both sides of the bottom of the box 205, and two sets of support rods 207 are installed on both sides of the bottom of the box 205. Cabinet doors 206 are installed on the front and back sides of the box 205 through hinges. The box 205 can provide installation positions for surrounding components. A cooling fan and a PLC control unit are installed inside the electrical box 203, which can control the electronic components inside the device and cool the electronic components with air to ensure that the device can maintain stability in a continuous working state. The casters 204 can support the box 205 and facilitate the movement of the box 205, thereby improving the mobility of the device. The support rods 207 can support the box 205, so that after the device moves to the specified position, the device is limited and the influence of uneven ground on the stability of the device is eliminated, so that the device can maintain a stable connection with other equipment.

[0024] Furthermore, a guide cover is installed on the top of the processing table 2, located on the right side of the first reversing wheel 208 and on the left side of the second reversing wheel 209, and the guide cover is a semicircular plate. The guide cover can cooperate with the first reversing wheel 208 and the second reversing wheel 209 to guide the dough to move inside the device and then reverse inside the S-shaped channel.

[0025] Furthermore, a booster pump 103 is fixedly installed on one side of the top of the connecting plate 102, and two guide pipes 104 are fixedly installed on the output end of the booster pump 103. The guide pipes 104 are connected to several nozzles 106. The booster pump 103 adopts the NK-CL-3030 model. After the booster pump 103 is powered on, it can suck the steam inside the water tank 3, and then transmit the steam to the several nozzles 106 through the guide pipes 104, so that the steam enters the interior of the front shell 101 and the rear shell 1 from the nozzles 106.

[0026] Furthermore, a temperature sensor 107 is fixedly installed on the inner wall of the rear shell 1, and a humidity sensor 108 is fixedly installed on the inner wall of the rear shell 1. The temperature sensor 107 adopts the AD592ANZ type, and the humidity sensor 108 adopts the RS495 type. The temperature sensor 107 and the humidity sensor 108 can respectively detect the ambient temperature and ambient humidity inside the front shell 101 and the rear shell 1, so as to facilitate the knowledge of the actual temperature and humidity inside the front shell 101 and the rear shell 1. If the actual ambient temperature and ambient humidity deviate from the set value, the booster pump 103 is controlled to introduce steam into the front shell 101 and the rear shell 1, so as to eliminate the deviation value of humidity and temperature, thereby ensuring that the dough can have a stable environment during the processing process, and avoiding the dough being affected by the ambient temperature and ambient humidity and resulting in poor shaping effect.

[0027] Furthermore, several groups of spiral coils 307 are fixedly installed inside the water tank 3, and the spiral coils 307 are connected in series. An electric power controller 305 is fixedly installed on one side of the water tank 3, and the electric power controller 305 is electrically connected to the spiral coils 307. The spiral coils 307 can generate heat when energized, thereby heating the clean water in the water tank 3, so as to heat the clean water and steam. The heat is transferred to the front shell 101 and the rear shell 1 by using steam to ensure that the dough can be processed in a constant temperature and humidity environment. The electric power controller 305 can be electrically connected to the main control box 303, and the electric power controller 305 is energized by the main control box 303, so that the electric power controller 305 provides currents of different powers to the spiral coils 307, thereby generating heat to heat the clean water and steam when the spiral coils 307 are energized.

[0028] Furthermore, two sets of guide frames 309 are fixedly installed on the inner wall of the water tank 3, and longitudinally distributed grooves are provided on the guide frames 309. The installation height of the guide frames 309 is higher than the spiral coil 307. The guide frames 309 can limit the cross bar 306, so that the cross bar 306 moves longitudinally under the buoyancy of clean water, and the atomizer 308 is always working on the water surface.

[0029] Furthermore, a cross bar 306 is slidably installed between the guide frames 309. The cross bar 306 is a lightweight hollow tubular object, and a number of atomizers 308 are fixedly installed at equal intervals inside the cross bar 306. The cross bar 306 can float on the water surface with the help of buoyancy, so that the atomizer 308 is always in contact with the water surface. After the atomizer 308 is powered on, it can use ultrasound to atomize water into steam, and then use the form of gaseous water to introduce the hot water vapor into the rear shell 1 and the front shell 101, so as to adjust the ambient temperature and humidity inside the rear shell 1 and the front shell 101.

[0030] Furthermore, a suction pipe 301 is fixedly installed on one side of the top of the cover plate 302, and the input end of the suction pipe 301 is on the same horizontal plane as the bottom surface of the cover plate 302. A funnel 304 is fixedly installed on one side of the top of the cover plate 302, and the funnel 304 extends to the bottom surface of the cover plate 302. The suction pipe 301 can facilitate the booster pump 103 to suck the steam inside the water tank 3, and the funnel 304 can facilitate the addition of clean water into the water tank 3. A butterfly valve is installed at the connection position between the funnel 304 and the cover plate 302, which can control the opening and closing of the internal pipe of the funnel 304, thereby preventing steam from being discharged from the water tank 3 through the funnel 304.

[0031] Working principle: After the device is assembled, add clean water into the water tank 3, close the butterfly valve at the bottom of the funnel 304, and drive the motor to rotate, respectively driving the first transmission belt 211, the second transmission belt 210, the first transmission belt 211 and the second transmission belt 212 to roll, and at the same time, the driving motor drives the first reversing wheel 208 and the second reversing wheel 209 to rotate, and the temperature sensor 107 and the humidity sensor 108 on the inner wall of the rear shell 1 are used to detect the ambient temperature and humidity inside the rear shell 1 and the front shell 101, and then the detection data is fed back to the main control box 303, and the main control box 303 transmits current to the electric power controller 305, so that the spiral coil 307 generates heat after being energized to heat the clean water, and at the same time, the inside of the water tank 3 The temperature detector and humidity detector detect the ambient temperature and humidity inside the water tank 3. When the ambient temperature and humidity inside the water tank 3 reach the set value, the clean water is atomized by the atomizer 308. At the same time, the booster pump 103 sucks the water vapor inside the water tank 3 and transmits the water vapor with heat to the multiple nozzles 106. The water vapor is evenly sprayed inside the front shell 101 and the rear shell 1, and the ambient temperature and humidity inside the front shell 101 and the rear shell 1 are adjusted until the ambient temperature and humidity inside the front shell 101 and the rear shell 1 reach the set value. The device then intermittently maintains the ambient temperature and humidity by spraying steam into the front shell 101 and the rear shell 1. When shaping steamed buns, the dough enters the device through the first conveyor belt 202, and the guide plate 201 cooperates with the first conveyor belt 211 to move the dough horizontally, and at the same time, knead the dough to make it rotate. When the dough is transmitted to the right end of the first conveyor belt 211, the dough is guided by the first reversing wheel 208 and changes its moving direction through the guide cover, so that the dough enters between the second conveyor belt 212 and a group of guide plates 201 located in the middle. The second conveyor belt 212 drives the dough to move to the left until it contacts the guide cover on the left side of the second reversing wheel 209, and then the second conveyor belt 212 and the guide cover change the direction of the dough again, so that the dough enters between the second conveyor belt 212 and a group of guide plates 201 located at the front end, and contacts the second conveyor belt 210, so that the dough moves horizontally to the right while rotating, thereby realizing the shaping of the dough. The shaped dough is moved out from the rightmost side of the device and enters the subsequent processing equipment.
