Detailed Description
The invention will be further described with reference to the accompanying drawings.
The cartoon bag comprises a frame 1, a conveying belt 2 extending in the front-back direction along the conveying direction is arranged on the frame 1, and a first induction switch 3, a second induction switch 4 and a third induction switch 5 are sequentially arranged on the frame from back to front along the conveying direction of the conveying belt 2. The conveyor belt 2 comprises a first conveyor belt 21 and a second conveyor belt 22 which are arranged from back to front in sequence, and the conveying directions of the two conveyor belts are consistent, so that the dough point green bodies are conveyed forwards continuously by the second conveyor belt 22 when moving to the foremost end of the first conveyor belt 21.
First inductive switch 3 is provided with before and is used for wetting a little unburned bricks surface water spray mechanism 6, and when conveyer belt 2's relevant position department had a little unburned bricks when first inductive switch 3 senses, control water spray mechanism 6 was sprayed water to a little unburned bricks so that a little unburned bricks surface is moist.
The second inductive switch 4 is disposed between the first conveyor belt 21 and the second conveyor belt 22, and is electrically connected to a first control switch for controlling the start and stop of the first conveyor belt 21. The dough point green compacts move forward along with the conveyer belt 2 to the second inductive switch 4 for detecting the quantity of the two adjacent dough point green compacts, and when the second inductive switch 4 detects that the distance between the two adjacent dough point green compacts is smaller than a set value, the second inductive switch 4 triggers the first control switch to enable the first conveyer belt 21 to stop operating so as to pull open the distance between the two adjacent dough point green compacts. After the previous one of the dough point green bodies moves forward for a certain distance until the distance between the two dough point green bodies meets the set value, the second inductive switch 4 triggers the first control switch again to enable the first conveyor belt 21 to continue to operate so as to convey the dough point green bodies forward.
Still be fixed with deflector 7 on the frame 1, deflector 7 sets up in the conveyer belt top and at least including setting up the baffle on 2 right sides of conveyer belt, and the baffle lower extreme is close to the transfer plane of conveyer belt, and the setting of baffle can avoid along the preceding face point unburned bricks off tracking that transports of conveyer belt 2. In other embodiments, the baffle can also be arranged at the left side or the left and the right sides of the conveying belt.
The front side of the third inductive switch 5 on the frame 1 is provided with a noodle pressing mechanism 8, a skinning mechanism 9, a stepping mechanism 10, a waste noodle recovery device 11 and an electric control part 12 electrically connected with the third inductive switch. The noodle pressing mechanism 8, the stepping mechanism 10, the veneer gluing mechanism 9 and the waste noodle recovery device 11 are sequentially arranged along the left and right direction.
The dough pressing mechanism 8 is used for pressing the wet dough into a flaky dough sheet, a plurality of conveying rollers for conveying the dough sheet are arranged on the rack, the conveying rollers are arranged from the outlet of the dough sheet of the dough pressing mechanism 8 on the right side to the feeding port of the waste dough recovery device 11 on the left side at intervals, and the conveying roller on the left end in the arrangement direction is positioned right above the feeding port of the waste dough recovery device 11, so that the waste dough with the skin cut off five sense organs can enter the waste dough recovery device 11 from the feeding port and be recovered by the waste dough recovery device 11. The recovered waste noodles can be sent into the noodle pressing mechanism 8 again manually or by an automatic conveying device to realize the working cycle. The conveying roller at the right end is used for being driven by the stepping mechanism 10 to convey the dough sheet. In order to avoid the deformation of the dough sheet, a dough sheet conveyor belt is arranged on the plurality of conveying rollers and is positioned above the conveying belt 2 in the up-down direction.
The skin sticking mechanism 9 comprises a machine body, a vacuum generator and a top core which is telescopically arranged at the end part of the machine body, the interior of the top core is of a hollow structure, and the upper end of the top core is communicated with an air supply port of the vacuum generator, so that the vacuum generator can pump air out of the top core to enable the interior of the top core to form a negative pressure environment which is enough to suck up small samples of five sense organs; the vacuum generator sends the outside air into the top core, and the five sense organs adsorbed at the end part of the top core can be blown out. Meanwhile, the two sets of the skin sticking mechanisms 9 are mutually independent, and the lower end of the top core of each set of the skin sticking mechanism is provided with a facial organ model which is suitable for the shape of the corresponding facial organ to press the corresponding facial organ sample, so that the top core can also be used as a mold for pressing the facial organ sample in the wrapper. Specifically, one set of skinning mechanism is used to stamp and post the thumbnail corresponding to both eyes, and one set of skinning mechanism is used to stamp and post the thumbnail corresponding to nose/mouth. In the specific position of five sense organs, the skin sticking mechanism provided with the eye mold is arranged on the rack along the vertical direction, and the skin sticking mechanism provided with the nose/mouth mold is obliquely arranged on the rack. Because the up end of face point unburned bricks is the cambered surface, and eyes and nose/mouth are located different high position department, so use different skinning mechanism to post different facial features galley proof can be according to the corresponding position of different facial features galley proof, the flexible height of adjusting the apical lamella in a flexible way to guarantee product appearance. Of course, in other embodiments, in the case that the heights of the various small samples of the five sense organs are not different, the end of the top core of one set of skin attaching mechanism can be provided with a mold corresponding to all the small samples of the five sense organs.
When the green pastry moves to the position corresponding to the third inductive switch 5 along with the second conveyer belt 22, the third inductive switch 5 triggers the second control switch electrically connected with the second inductive switch to stop the second conveyer belt 22, and at this time, the green pastry stops at the set position along with the second conveyer belt. The position at which the green compact is parked can be adjusted by adjusting the delay time of the control motor that controls the second conveyor belt 22.
When the third inductive switch 5 detects that the second conveying belt 22 completely stops, the electric control part 12 is triggered, the electric control part 12 controls the dough pressing mechanism 8 to press dough sheets, the dough sheets flowing out of the discharge port are placed on the conveying faces of the dough sheet conveying belts, and the stepping mechanism 10 drives the dough sheet conveying belts to move leftwards through the conveying rollers on the right side. The dough sheet conveyor belt comprises a first dough sheet conveyor belt on the right side and a second dough sheet conveyor belt on the left side, and the first dough sheet conveyor belt and the second dough sheet conveyor belt are arranged in a left-right connection mode. The conveying stroke of the first panel conveying belt on the right side extends to the right side of the skinning mechanism 9 from the lower part of the face pressing mechanism 8, and the second panel conveying belt is positioned below the skinning mechanism 9. The second panel conveyer belt includes two belts that the interval set up in the front and back direction, and the clearance between two belts forms and supplies the apical core to pass through in order to paste the skin hole on the face point unburned bricks with the sense organ galley proof. In order to ensure that the dough sheets can move forwards along with the dough sheet conveyor belt, a press roller is arranged on the first dough sheet conveyor belt in a vertically floating mode. In operation, a pressure roller is positioned above the dough sheet to increase the friction between the dough sheet and the first dough sheet conveyor. In other embodiments, the first panel conveyer belt can be omitted, and only the conveying starting point of the second panel conveyer belt needs to be arranged below the surface pressing mechanism.
When the stepping mechanism 10 moves one step forward, the dough sheet conveyor belt moves a certain distance leftwards, and after the dough sheet moves to the second dough sheet conveyor belt, the top core is controlled to extend out, so that the five sense organs sample can be pressed on the dough sheet. After the top core presses the small samples of the five sense organs on the dough sheet, the vacuum generator extracts the gas in the top core to adsorb the corresponding small samples of the five sense organs at the end part of the top core. The top core with the facial features small sample picked up at the end part continuously extends downwards through the skin sticking hole, the vacuum generator supplies air to the top core to stick the facial features small sample at the end part of the top core at the corresponding position of the dough point green body, the dough point green body after the facial features small sample is stuck forms a cartoon bag with a cartoon shape, and the cartoon bag can be conveyed to the next station along with the second conveying belt by starting the second control switch.
Because the pick-up and the sticking of the small samples of the five sense organs are realized by air pressure, the force applied to the small samples of the five sense organs is small and uniform, the small samples of the five sense organs cannot be damaged, and the appearance of the manufactured cartoon bag is more attractive.
In other embodiments, the first inductive switch and the water spraying mechanism can be omitted under the condition that the surface of the manufactured pastry green body is wet; the third inductive switch and the second control switch can be omitted, and the start and stop of the second conveying belt and the actions of mechanisms for pressing the dough, stepping, pasting the skin and the like can be manually controlled after the dough point green bodies are conveyed in place. The second inductive switch and the first control switch for detecting and pulling the distance between two adjacent surface point green bodies can be omitted.
