The returned mold tray 13 enters the empty tray elevator 1 through the empty tray elevator entrance 11 and rises, and then moves backward through the empty tray elevator exit 12. Above the feeding and tray loading machine 2 is the feeding port and below is the vibrating disk. The vibrating disk is used to drive the mold tray 13 to reciprocate so that the betel nuts falling from the feeding port can enter the female mold of the mold tray 13. The vibrating disk is provided with a limiter for fixing the mold tray 13, so that when the mold tray 13 enters the vibrating disk, it can reciprocate with the vibrating disk. At this time, the betel nuts falling on the surface of the mold tray 13 are shaken loose so that they can be evenly dropped into the female mold.

[0019] Refer to Figure 1 and Figure 2 As shown, the tail of the feeding and tray loading machine 2 is connected to the manual feeding machine 3. Inside the manual feeding machine 3, there is a vision and laser system 31 for identifying the vacant female molds on the mold tray 13, visually inspecting the mold tray 13 entering the manual feeding machine 3, and using laser dots to mark the empty female molds, so as to facilitate manual feeding to ensure that all the female molds on the mold tray 13 are filled with betel nuts.

The scraper can be controlled by a motor or hydraulics. When the punch rises to the highest position, the scraper is controlled to move along the surface of the punch to shovel out the foreign matters remaining on the surface of the punch. The punch is evenly provided with protrusions. Therefore, corresponding grooves can be opened on the scraper, and scrapers that can move horizontally and vertically can be provided to ensure the cleaning effect. Among them, the tail of the second precision pressing and shaping machine 6 is connected to the tray buffer machine 7, and the tail of the tray buffer machine 7 is connected to the flipping and discharging machine 8. The two mold trays 13 formed by the first precision pressing and shaping machine 5 and the second precision pressing and shaping machine 6 are successively conveyed to the tray buffer machine 7 and the flipping and discharging machine 8 to simultaneously process the two mold trays 13 by the first precision pressing and shaping machine 5 and the second precision pressing and shaping machine 6, improving the processing efficiency. After the processing is completed, both mold trays 13 move backward two workstations. Among them, the mold tray 13 removed from the second precision pressing and shaping machine 6 flows into the flipping and discharging machine 8 through the tray buffer machine 7, while the mold tray 13 removed from the first precision pressing and shaping machine 5 enters the tray buffer machine 7 through the second precision pressing and shaping machine 6 and waits. During the waiting process, the front rapid heating machine 4 can continue to heat the betel nut inside it.

[0022] Reference Figure 1 As shown in the reference, the front end of the flipping and discharging machine 8 is provided with a flipping and discharging machine inlet 81, the rear end is provided with a flipping and discharging machine outlet 82, and inside the flipping and discharging machine 8, there is also a flipping disk for controlling the flipping of the mold tray 13. A limiter for fixing the mold tray 13 is provided on the flipping disk so that the mold tray 3 can rotate together with the flipping disk. The flipping disk is controlled by a motor and can rotate 180 degrees at a time. A discharging bucket 83 is installed below the inside of the flipping and discharging machine 8. The flipping and discharging machine 8 is internally provided with an ejecting device adapted to the female mold of the mold tray 13. After the mold tray 13 rotates 180 degrees, the opening inside the female mold faces downward, and the betel nut inside is ejected through the ejecting device and falls downward into the discharging bucket 83.

[0023] Reference Figure 1As shown, the tail of the tipping and blanking machine 8 is connected to the vision inspection machine 9. The vision inspection machine 9 includes a vision system 91 at the top to detect the mold tray 13 when it enters. The front side above the vision inspection machine 9 is the empty tray lifting and vision inspection entrance 92, and the rear side below is the cleaning end exit 93. The cleaning end exit 93 corresponds to the foreign object tray removal and cleaning machine 10. The inspection is used to classify the mold tray 13. When there are residues on the mold tray 13, it will pass through the front end below the vision inspection machine 9, which is the reflux end exit 94. The mold tray 13 passes through the reflux conveyor line 14 and then enters the foreign object tray removal and cleaning machine 10 through the cleaning end exit 93 for cleaning. The cleaned mold tray 13 returns to the vision inspection machine 9 and then refluxes to the empty tray elevator 1 through the reflux conveyor line 14, so as to realize the recycling of the mold tray 13 and ensure the cleanliness of the surface of the refluxed mold tray 13.

[0024] Reference Figure 1 and 5 As shown, the mold tray 13 is made of edible aluminum. The mold tray 13 is fixed with a plurality of female molds through corresponding limiting devices.

Embodiment 2

[0025] The production method of the betel nut shaping automation equipment includes the following steps: Step 1: The mold tray 13 is conveyed from the empty tray elevator exit 12 to the loading and upper tray machine 2, and the loading work is carried out through the loading and upper tray machine 2. Step 2: After the loading of the mold tray 13 is completed, it is conveyed to the manual feeding machine 3. The vision and laser system 31 identifies the mold vacancies, the laser projects the mold vacancies, and the worker completes the vacancy feeding according to the projection points to ensure that all the female molds on the surface of the mold tray 13 are filled, so as to improve the efficiency and facilitate counting at the same time. Step 3: The mold tray 13 after manual feeding is conveyed to the rapid heating machine 4 and runs for a specific time on the heating machine conveyor line 43 to ensure that the betel nut reaches the required temperature before the mold tray 13 leaves the heating box. The high-temperature betel nut is convenient for the subsequent pressure forming work. Step 4: The mold tray 13 leaves the rapid heating box and is conveyed to the first precision pressing and shaping machine 5 and the second precision pressing and shaping machine 6. Every two mold trays 13 form a group, and each of the first precision pressing and shaping machine 5 and the second precision pressing and shaping machine 6 is assigned one mold tray 13. The hot water is introduced into the fixed plate of the mold tray 13 to keep the betel nuts inside at a high temperature, and the hot water is introduced into the fixed plate of the punch to preheat the punch, so as to reduce the temperature difference between the punch and the mold tray 13. The servo motor drives the press punch to press and shape the betel nuts, and maintain for a specified time. Then, the cold water is introduced into the fixed plate of the punch and the fixed plate of the mold tray 13 to cool and shape the betel nuts. After the shaping is completed, the punch rises, and the automatic scraper removes the foreign matters adhered to the punch to ensure the cleanliness of the punch surface, so as to facilitate the next pressing operation; Step 5: The mold tray 13 leaves the first precision pressing and shaping machine 5 and the second precision pressing and shaping machine 6. Every two mold trays 13 form a group. The mold tray 13 flowing out of the second precision pressing and shaping machine 6 is conveyed to the flipping and blanking machine 8 after passing through the tray buffer machine 7, and the mold tray 13 flowing out of the first precision pressing and shaping machine 5 is conveyed to the tray buffer machine 7 and waits. The flipping and blanking machine 8 flips the mold tray 13, and the ejecting device ejects the betel nuts from the mold. The betel nuts fall into the blanking bucket, and then the mold tray 13 is reset; Step 6: The mold tray 13 leaves the flipping and blanking machine 8 and is conveyed to the vision inspection machine 9 for inspection. The tray lifter 95 conveys the mold tray 13 from the upper layer of the production line to the lower layer of the production line. During the conveying process, the vision system 91 identifies the contaminated mold, and the contaminated mold tray 13 is output from the cleaning end outlet 93 and conveyed to the foreign matter tray removal and cleaning machine 10. After the cleaning is completed, the mold tray 13 returns to the production line from the cleaning end outlet 93; Step 7: The mold tray 13 is output from the return end outlet 94, and reaches the empty tray lifter 1 through the return conveying line 14.

[0026] Step 8: The empty tray lifter 1 conveys the mold tray 13 from the lower layer of the production line to the upper layer of the production line, reaches the empty tray lifter outlet 12, and enters the next cycle.

[0027] Working principle: During use, the mold tray 13 forms a cycle through the upper and lower conveying lines and the return conveying line 14, and realizes the transfer between the upper and lower layers through the empty tray elevator 1 and the tray elevator 95 inside the vision inspection machine 9. After the mold tray 13 moves to the blanking upper tray machine 2 through the empty tray elevator 1, it is placed on the vibrating tray and simultaneously under the material inlet. A limiter is provided on the vibrating tray to fix the mold tray 13. Then, the built-in motor is started, and the vibrating tray is driven to reciprocate by the eccentric wheel, and then the mold tray 13 is driven to reciprocate, so that the betel nuts falling from the feed inlet can enter the concave mold on the surface of the mold tray 13. The mold tray 13 moves backward into the manual feeding machine 3 and is detected by the vision and laser system 31. After detecting the empty concave mold, it is marked by laser. At this time, the operator supplements the betel nuts according to the laser marking points, and then enters the rapid heating machine 4 through the rapid heating machine inlet 41 to heat the betel nuts. The heating time is controlled by controlling the speed of the heating machine conveying line 43. Electric heating rods and temperature controllers are provided inside the rapid heating machine 4. The front and back of the first precision pressing and shaping machine 5 are the first precision pressing and shaping machine inlet 52 and the first precision pressing and shaping machine outlet 53 respectively. The front and back of the second precision pressing and shaping machine 6 are the second precision pressing and shaping machine inlet 62 and the second precision pressing and shaping machine outlet 63 respectively. Two heated mold trays 13 move synchronously in a group and enter the first precision pressing and shaping machine 5 and the second precision pressing and shaping machine 6 through the first precision pressing and shaping machine inlet 52 and the second precision pressing and shaping machine inlet 62 respectively; After the mold tray 13 enters the first precision pressing and shaping machine 5 and the second precision pressing and shaping machine 6, hot water is introduced into the mold tray 13 and the fixing plate of the punch to heat. The downward movement of the punch is controlled by the internal servo motor to press and form the betel nuts in the concave mold of the mold tray 13. Then, cold water is injected into the mold tray 13 and the fixing plate of the punch to accelerate the shaping. After shaping, the upward movement of the punch is controlled, and the residues on the punch are cleaned by the first automatic scraper 51 and the second automatic scraper 61 respectively. The two mold trays 13 continue to move forward, one enters the flipping and blanking machine 8 for blanking, and the other enters the tray buffer machine 7 to wait; After the mold tray 13 enters the tipping and blanking machine 8, it will be placed on the tipping plate. Limiters are provided on the tipping plate to ensure the fixation of the mold tray 13 and the tipping plate. Then, the tipping plate is rotated 180° by the motor control, and the betel nuts formed in the female mold of the mold tray 13 are ejected downward by the internal ejecting device and fall into the blanking barrel 83. After blanking, the tipping plate rotates 180° again to return to its original position and moves into the vision inspection machine 9. The vision inspection machine 9 inspects the material mold tray 13 and descends. The conveyor lines below the vision inspection machine 9 and the conveyor line of the foreign object tray removal and cleaning machine 10 are both two-way conveyor lines. Therefore, the detected mold tray 13 with residues will move backward to the foreign object tray removal and cleaning machine 10 for cleaning. After cleaning, it will return to the inside of the vision inspection machine 9, while the mold tray 13 without detected residues will directly move forward and return to the empty tray elevator 1 through the return conveyor line 14.
