Detailed Implementation

[0040] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0041] First aspect

[0042] The first embodiment of this application is as follows:

[0043] Please see Figures 1 to 15The lead-free preserved egg processing system of this embodiment includes a mixing tank 101, a stirring shaft 102 rotating in the mixing tank 101, a rotating tube 103 sleeved on the stirring shaft 102, a rotating rod 104 fixed to the rotating tube 103, a vertical rod 105 fixed to the rotating tube, multiple mixing rods 106 fixed to the inner side of the vertical rod 105, multiple mixing plates 107 fixed to the outer side of the vertical rod 105, two scraping mechanisms, a mud-coating mechanism, and a fermentation mechanism; the scraping mechanism includes a scraping plate 109, a first spring 110, two magnets 111, and two electromagnets 112; The mud-coating mechanism includes a gear 116, two moving components, a receiving box 124, and a return pipe 125. The moving components include a rack 117, a sliding box 118, a sliding plate 119, multiple mud-coating placement parts, and multiple rotating parts. Each mud-coating placement part includes four columns 120 and a placement tray 121 with through holes. Each rotating part includes a rotating shaft 122 and a soft brush 123. The fermentation mechanism includes a fermentation tank 126 and two sliding parts. Each sliding part includes a first lead screw 128, a mounting base 129, a second lead screw 130, a slider 131, and a fixed cylinder 132. This solution solves the problem in the prior art where raw materials easily adhere to the inner wall of the mixing tank 101, are difficult to scrape off, and lead to material waste.

[0044] In this embodiment, the lead-free preserved egg processing system also includes multiple motors and a controller. A motor is a device that converts electrical energy into mechanical energy; the rotation is caused by the force exerted by a magnetic field on an electric current, which in turn drives the rotation of connected structures, such as motor A, motor B, motor C, and motor D. The controller includes a program counter, an instruction register, an instruction decoder, a timing generator, and an operation controller, used to drive the motors and other electronic devices. The controller is connected to multiple motors, electromagnet 112, a first solenoid valve 143, and a second solenoid valve 137. The mixing tank 101 has a feed inlet 108 through which the raw materials to be mixed enter the mixing tank 101. Two scraping mechanisms are located between the two vertical rods 105 and the mixing tank 101, respectively, and are used to scrape off the raw materials adhering to the inner wall of the mixing tank 101. The scraper plate 109 has multiple sliding grooves 113 and multiple placement grooves 114. The sliding grooves 113 are adapted to the mixing plate 107, and the placement grooves 114 are used to place the first spring 110. The sliding grooves 113 and the placement grooves 114 are alternately arranged. Multiple mixing plates 107 are respectively inserted into multiple sliding grooves 113 and slidably connected to the scraper plate 109. The two ends of the first spring 110 are respectively fixedly connected to the scraper plate 109 and the vertical rod 105, and are located in the placement groove 114. When it is not necessary to scrape the inner wall of the mixing tank 101, the scraper plate 109 is attached to the vertical rod 105, and the first spring 110 is located in the placement groove 114 and is in a free extension state. Two magnets 111 are fixedly connected to the scraper plate 109 and located on both sides of the scraper plate 109. Two electromagnets 112 are fixedly connected to the vertical rod 105 and are respectively arranged opposite to the two magnets 111. The electromagnet 112 is a device that generates electromagnetism when energized. When scraping the inner wall of the mixing tank 101 is not required, the electromagnet 112 is not energized and has no magnetism. When scraping the inner wall of the mixing tank 101 is required, the electromagnet 112 is energized and has the same magnetism as the magnets 111. Like poles repel each other, creating a gap between the scraper plate 109 and the vertical rod 105. The mixing plate 107 slides towards the inner wall of the mixing tank 101 until it contacts the inner wall of the mixing tank 101 without detaching from the mixing plate 107. The stirring shaft 102 rotates through a rotary motor, drive wheel, belt, and driven wheel, thereby driving multiple mixing plates 107 and multiple mixing rods 106 to rotate and fully mix the raw materials in the mixing tank 101. At the same time, the scraper 109 scrapes off the raw materials adhering to the inner wall of the mixing tank 101 as the stirring shaft 102 rotates, avoiding the raw materials from adhering to the inner wall and causing waste, and also avoiding the imbalance of the raw material ratio, which would result in poor mud coating effect and poor quality of preserved eggs.

[0045] The mud-coating mechanism is located below the mixing tank 101 and is used to coat eggs or duck eggs with mud. The fermentation mechanism is located on one side of the mixing tank 101 and the mud-coating mechanism and is used to ferment the mud-coated eggs or duck eggs at a constant temperature. The bottom of the mixing tank 101 has two discharge ports 115, and each of the two discharge ports 115 is equipped with a first solenoid valve 143. The first solenoid valve 143 is an automated component used to control the fluid. The raw materials mixed in the mixing tank 101 are discharged by opening and closing the first solenoid valve 143. The gear 116 is located below the mixing tank 101. The gear 116 is connected to the output end of the motor A via a central shaft. The motor A drives the gear 116 to rotate. Two moving components are located on either side of the gear 116, used to move and coat eggs or duck eggs with mud. The rack 117 meshes with the gear 116, thereby driving the two racks 117 to move back and forth in opposite directions. The sliding box 118 is fixedly connected to the rack 117 and located on the side away from the gear 116, thereby driving the two sliding boxes 118 to move back and forth in two directions. The sliding box 118 has an opening at the top. The unit has a rectangular structure with a cavity, and a slide rail is provided inside. A baffle 142 is provided on the side of the sliding box 118 near the fermentation mechanism. The baffle 142 is fixed to the rotating shaft, which is connected to the output end of the motor B. The motor B drives the rotating shaft to rotate, which in turn drives the baffle 142 to rotate and block the outlet of the sliding box 118. The sliding plate 119 is slidably connected to the sliding box 118 through the slide rail, and moves back and forth below the mixing tank 101 as the sliding box 118 moves back and forth. Multiple mud-coating placement pieces are evenly distributed on the sliding plate 119 for placing eggs or duck eggs to be coated with mud. Four pillars 120 are fixedly connected to the sliding plate 119 and located above the sliding plate 119. There is a gap between the four pillars 120. The placement tray 121 with through holes is fixedly connected above the four pillars 120. Eggs or duck eggs are placed in the through holes of the placement tray 121 with through holes, and the bottom is located on the sliding plate 119. Eggs or duck eggs of different sizes can be placed. As the gear 116 rotates, it drives one of the sliding boxes 118 to move below the discharge port 115 corresponding to the bottom of the mixing tank 101. The first solenoid valve 143 connected to it opens, and the stirred raw materials fall from above the eggs or duck eggs to the sliding box 118. The raw materials in the sliding box 118 coat the eggs or duck eggs with mud through the gap between the four pillars 120. At the same time, it drives another sliding box 118 to move away from the fermentation mechanism to feed the sliding plate 119, which is where the eggs or duck eggs to be coated with mud are placed.Two rotating parts are positioned opposite each other on both sides of the sliding plate 119 for coating eggs or duck eggs with mud. One end of the rotating shaft 122 is connected to the output end of the motor C, and the other end of the rotating shaft 122 is rotatably connected to the sliding plate 119 and fixedly connected to the soft brush 123. The motor C drives the rotating shaft 122 to rotate, which allows the soft brush 123 to scrape and adhere the raw materials stored in the sliding box 118. As the sliding box 118 moves, the soft brush 123 coats the surface of the eggs or duck eggs with mud, increasing the coating area and the number of times, thereby improving the coating effect. The receiving box 124 is located between the moving component and the fermentation mechanism. When the baffle 142 rotates and does not enclose the sliding box 118, as the sliding plate 119 moves towards the fermentation mechanism, scraping blocks 141 on both sides of the sliding plate 119 scrape excess raw materials to the receiving box 124. The return pipe 125 connects the receiving box 124 and the mixing tank 101, and the return pipe 125 also enables the recycling of raw materials, saving resources. The fermentation box 126 is located on one side of the mixing tank 101 and has a temperature control device inside to keep the fermentation box 126 at a constant temperature, which is convenient for the fermentation of eggs or duck eggs after being coated with mud. The two sliding parts are respectively arranged opposite to the two moving components to move the sliding plate 119 into the fermentation box 126. The sliding plate 119 has a through groove 127 located on the side near the fermentation tank 126 and adapted to the fixed cylinder 132. A motor D is installed inside the fermentation tank 126, and the output end of the motor D is fixedly connected to the first lead screw 128, thereby driving the first lead screw 128 to rotate. The first lead screw 128 passes through the mounting base 129, and the first lead screw 128 and the mounting base 129 respectively have mutually engaging external and internal threads, thereby allowing the mounting base 129 to slide in and out of the fermentation tank 126. A motor is installed inside the mounting tank. E, the output end of motor E is connected to the second lead screw 130, driving the second lead screw 130 to rotate. The second lead screw 130 passes through the slider 131, and the second lead screw 130 and the slider 131 have mutually cooperating external threads and internal threads, thereby causing the slider 131 to move up and down along the second lead screw 130. The fixed cylinder 132 is fixedly connected to the slider 131 and is movably inserted into the through groove 127. The fixed cylinder 132 has a movable circular groove in the middle, which facilitates the fixed cylinder 132 to move synchronously with the up and down movement of the slider 131.The sliding box 118 moves toward the fermentation box 126, and the fixed cylinder 132 moves toward the through groove 127 of the sliding plate 119 until it is located in the through groove 127. The baffle 142 opens, and the mounting base 129 moves toward the interior of the fermentation box 126, thereby driving the sliding plate 119 to detach from the sliding box 118 and enter the fermentation box 126 for fermentation.

[0046] In addition, the vertical rod 105 has a first cavity 133, which is connected to the inner cavity of the mixing tank 101 and is equipped with a third solenoid valve. The scraping mechanism also includes a feed pipe 134 and a feeding rod 135. The feed pipe 134 is located on one side of the discharge port 115, one end of the feeding rod 135 is located below the feed pipe 134, and the other end of the feeding rod 135 is connected to the first cavity 133. The feed inlet 108 is used for feeding raw materials such as soda ash, salt, wood ash, black tea powder, and boiling water. The feed pipe 134 is used for feeding quicklime. The feeding rod 135 has a hollow internal structure and is in the same vertical direction as the feed pipe 134. The outlet of the first cavity 133 is located between the first spring 110 and the mixing plate 107. When quicklime is fed, the feeding rod 135 is located below the feed pipe 134 as the stirring shaft 102 rotates. The quicklime enters the first cavity 133 through the cavity of the feeding rod 135, and then between the vertical rod 105 and the scraper plate 109. The electromagnet 112 is turned on and off to realize the contact and separation of the scraper plate 109 and the vertical rod 105, thereby achieving the clamping and crushing of granular quicklime, preventing the quicklime from becoming granular, and making the raw materials more fully and evenly mixed.

[0047] In addition, the lead-free preserved egg processing system also includes a cleaning mechanism, which includes a cleaning rod 136 and a plurality of second solenoid valves 137. The vertical rod 105 also has a second cavity 138, and the mixing rod 106 has a third cavity 139. One end of the cleaning rod 136 is rotatably connected to the mixing tank 101, and the other end is connected to the second cavity 138 and the third cavity 139 in sequence. The second solenoid valves 137 are disposed in the third cavity 139. The cleaning rod 136 has a hollow structure and is connected to an external water pipe. When stirring and mud coating are not required, water flows from the cleaning rod 136 into the second cavity 138 and the third cavity 139, and then flows to the stirring and mixing blades to clean them. In addition, the feed inlet 108 is connected to an external water pipe to clean the inner cavity of the mixing tank 101, improving the cleaning effect. Then, the first solenoid valve 143 is opened to clean the sliding box 118 and the receiving box 124, and the water is discharged from the water hole of the receiving box 124.

[0048] The working / implementation / use principle of this invention is as follows: Quicklime enters the feeding rod 135 and the first cavity 133 through the feed pipe 134. The electromagnet 112 is switched on and off, having the same magnetism as or no magnetism as the magnet 111, causing the scraper plate 109 to move away from or adhere to the vertical rod 105, thereby clamping and crushing the quicklime. Raw materials such as soda ash, salt, wood ash, black tea powder, and boiling water enter the mixing tank 101 through the feed inlet 108. A rotary motor drives the stirring shaft 102 to rotate, which in turn drives multiple mixing rods 106, multiple mixing plates 107, and multiple stirring blades to stir the raw materials in the mixing tank 101 cavity, so that the raw materials are fully and evenly mixed. After a preset mixing time, the electromagnet 112 is energized and has the same magnetism as the magnet 111. Since like poles repel each other, the scraper 109 slides along the mixing plate 107 until it contacts the inner wall of the mixing tank 101. The stirring shaft 102 continues to rotate, driving the scraper 109 to rotate and scrape off the raw materials adhering to the inner wall of the mixing tank 101. During the stirring and scraping process, the eggs or duck eggs to be coated with mud are placed on the perforated placement plate 201. A robotic arm then places the sliding plate 119 containing the eggs into the sliding box 118, driving the gear 116 to rotate. The rack 117 meshes with the gear 116, causing the sliding box 118 to move with the rack 117 to below one of the discharge ports 115. The first solenoid valve 143 corresponding to the discharge port 115 opens, allowing the stirred material to flow through the discharge port 115 to the eggs or duck eggs to be coated with mud, thus coating the upper area of ​​the eggs or duck eggs with mud. Excess material flows into the sliding box 118. The rack 117 continues to move, and the rotating shaft 122 rotates, causing the soft brush 123 to rotate and adhere to the inside of the sliding box 118. The raw materials are adhered to the lower half of the egg or duck egg for coating with mud. At this time, another sliding box 118 is located on the side away from the fermentation box 126 to facilitate the feeding of the egg or duck egg to be coated with mud. Then, the baffle 142 is rotated and opened, the first screw 128 and the second screw 130 are rotated, so that the mounting box slides above the through groove 127. The fixed cylinder 132 moves downward and inserts into the through groove 127. The first screw 128 rotates, driving the mounting seat 129 to slide into the fermentation box 126, thereby driving the mud-coated sliding plate 119 to slide away from the sliding box 118. The excess raw materials in the sliding box 118 fall into the receiving box 124 under the scraping of the scraper block 141. The mud-coated sliding plate 119 is located in the fermentation box 126, and the mud-coated egg or duck egg is fermented at a constant temperature.

[0049] The second embodiment of this application is as follows:

[0050] Please see Figures 16 to 18Based on the first embodiment, the lead-free preserved egg processing system of this embodiment also includes a drying mechanism, which includes a placement plate 201, a drying rack, a push plate 202 and multiple fixing components.

After fermentation, the mounting base 129 moves towards the drying rack, causing the fermented sliding plate 119 to move onto the placement plate 201. The push plate 202 is connected to the output end of the electric push rod, which is an electric drive device that converts the rotational motion of an electric motor into the linear reciprocating motion of a push rod. It can drive the push plate 202 to move back and forth. The electric push rod is connected to the controller. The electric push rod drives the push plate 202 to push the sliding plate 119 towards the drying rack. The drying rack and the placement plate 201 are detachably connected. After a preset number of fermented preserved eggs are placed on the drying rack, the drying rack can be pushed to the next process for natural air drying for 30 days, after which the quality of the preserved eggs is tested.

[0052] Specifically, the drying rack includes a first connecting plate 203, a second connecting plate 204, two third connecting plates 205, multiple isolation strips 206, and multiple fasteners. The first connecting plate 203 and the second connecting plate 204 are arranged opposite to each other. The first connecting plate 203 is detachably connected to the placement plate 201. The two ends of the two third connecting plates 205 are respectively fixedly connected to the two ends of the first connecting plate 203 and the second connecting plate 204. The multiple isolation strips 206 are evenly distributed between the first connecting plate 203 and the second connecting plate 204. Every two fasteners are arranged opposite to each other on the two third connecting plates 205. The first connecting plate 203, the second connecting plate 204, and the two third connecting plates 205 form a rectangular structure. The first connecting plate 203 and the upper surface of the placement plate 201 are on the same horizontal plane. The multiple isolation strips 206 have gaps and are arranged perpendicularly to the sliding plate 119 to avoid them being arranged in the same direction. The sliding plate 119 is engaged in the gap and cannot be pushed to the designated position. At the same time, it avoids the preserved egg from being damaged by vibration. In addition, the gap is also conducive to natural air drying. The fixing member is used to fix the multiple sliding plates 119 in different positions to prevent accidental contact that would cause adjacent sliding plates 119 to move and collide, thereby improving the quality of the preserved egg.

[0053] The fixing component includes a wedge block 207 and a second spring 208. The wedge block 207 is slidably connected to the third connecting plate 205. The two ends of the second spring 208 are fixedly connected to the wedge block 207 and the third connecting plate 205, respectively, and are located between the wedge block 207 and the third connecting plate 205. The wedge block 207 has an upper bottom edge, a lower bottom plate, a right-angled edge, and a hypotenuse. The right-angled edge is close to the second spring 208, and the upper bottom edge faces the sliding plate 119. The length of the upper bottom edge is less than the length of the lower bottom edge. When the sliding plate 119 is not in contact with the wedge block 207, the second spring 208 is in a freely extended state. When the sliding plate 119 is pushed by the push plate 202, the scraping block 141 abuts against the hypotenuse, and the second spring 208 is compressed. Due to the decomposition of force, the wedge block 207 slides into the third connecting plate 205 until it is completely slid into the third connecting plate 205. Inside the connecting plate 205, the sliding plate 119 continues to push, and the scraping block 141 of the sliding plate 119 disengages from the wedge block 207. The second spring 208 extends and drives the wedge block 207 to reset. The sliding plate 119 is located between the third connecting plate 205 and two of the oppositely arranged fixing members. The push plate 202 resets, and the above operation is repeated so that multiple sliding plates 119 are located between four adjacent fixing members and between the third connecting plate 205 and two adjacent fixing members, avoiding accidental contact that could cause two adjacent sliding plates 119 to move and collide, thus improving the quality of the preserved egg.

[0054] Secondly, the present invention also provides a method for processing lead-free preserved eggs, applied to the lead-free preserved egg processing system described in the first aspect, comprising the following steps:

[0055] According to the first stirring command, the stirring shaft 102 is driven to rotate, which in turn drives the multiple mixing rods 106 and the multiple mixing plates 107 to rotate and stir the raw materials.

[0056] According to the scraping command, the electromagnet 112 is energized and has the same magnetism as the magnet 111. Since like poles repel each other, the scraping plate 109 slides towards the inner wall of the mixing tank 101 and contacts the inner wall of the mixing tank 101.

[0057] According to the second stirring command, the stirring shaft 102 is driven to rotate, which in turn drives the scraper 109 to rotate and scrape the raw material from the inner wall of the mixing tank 101.

[0058] In this embodiment, please refer to the details of the first aspect, which will not be repeated here.
