The production process comprises the following steps:
firstly, the cut veneer is lifted to a first vacuum chuck 10 of a feeding device 77 by a bin lifting device 76, then the veneer is translated to a workbench 75 by the first vacuum chuck 10, an infrared diffuse reflection laser sensor a is arranged at the position, after the infrared diffuse reflection laser sensor a determines that the veneer is in place, a signal is sent to a TPC control system, then the TPC control system sends a command to a material pushing cylinder 7, the veneer is pushed to a glue dispensing station by a feeding push rod 9, an infrared diffuse reflection laser sensor b is arranged at the glue dispensing station, after the infrared diffuse reflection laser sensor b determines that the veneer reaches the designated position, the signal is sent to the TPC control system, then the TPC sends a command to a glue dispenser 28, glue dispensing is carried out on a veneer glue dispensing position 60 in a material 73 by a glue dispensing valve 30, after glue dispensing is finished, the TPC control system sends a command to a transmission servo motor 16, a straight lug push plate 14 arranged on a transmission chain 94 pushes the veneer to a forming station of the workbench 75, an infrared diffuse reflection laser sensor c is arranged at a forming station of the workbench 75, and after the wood skin is determined to reach a designated position by the infrared diffuse reflection laser sensor c, a signal is sent to the TPC control system, and then the TPC control system sends an action instruction to the multi-position cylinder 18, so that the action instruction is used for connecting the guide pillar on the fixing plate 58, and the inner die 85 falls on the wood skin by pressing down, so that the inner die 85 pressurizes and positions the wood skin. After positioning, the TPC control system sends a command to the bow outer membrane upward-folding driving cylinders 34, the other two bow outer membrane upward-folding driving cylinders 34 simultaneously move in the same direction to push the bow upward-folding push plates 44 upwards, so that the veneers simultaneously upward-fold and are tightly combined with the bow of the inner mold 85, after combination is completed, the TPC control system sends a command to the side outer membrane upward-folding driving cylinders 33 to push the same upwards, the movable ends of the side outer membrane upward-folding driving cylinders 33 push the guide post and guide sleeve mounting plates 38, then the side push rods 41 arranged on the guide post and guide sleeve mounting plates 38 push the side push rollers 45 to simultaneously lift the outer mold side upward-folding plates 2, so that the material side veneer upward-folding positions 63 are simultaneously upward-folded and are tightly combined with the left and right sides of the inner mold 85, and the motion is completed by the push rods in the outer mold driving device 20 mechanism,
after the actions are finished, the TPC control system sends instructions to the mechanical arm forming cylinder I1 and the mechanical arm forming cylinder II 3 in sequence to push the mechanical arm rubber coating roller 88 to enable the upper folding positions 63 of the side wood skin of the wood skin to move left and right respectively, so that the left and right sides of the wood skin are tightly attached to the left and right sides of the internal mold 85, after the actions are finished, the TPC control system sends instructions to the two clamp driving cylinders 54 to enable the two clamps to act, the clamps 52 are pushed in a lever mode to clamp the bow wood skin tightly, and then the forming process of the boat-shaped lunch box is finished preliminarily. After the clamp 52 finishes the action and keeps, the TPC control system releases all the keeping actions of the mechanical arm forming cylinder I1, the mechanical arm forming cylinder II 3, the upper folding driving cylinder 33 of the outer membrane of the ship side, the upper folding driving cylinder 34 of the outer membrane of the ship head and the multi-position cylinder 18, simultaneously, under the action of the ship model return pressure spring 59, the inner model 85 and the formed lunch box are integrally returned to the initial state of the inner model forming assembly 19, and meanwhile, the TPC control system sends an instruction to the turntable driving motor 22 of the rotary circulating turntable 80, so that the rotary turntable 55 stops after rotating according to the angle or the pulse number obtained by equally dividing the installation number of the inner model forming assembly 19, and the next inner model enters the working state.
The process flow comprises the steps of feeding, dispensing, forming and obtaining a finished product. On the use components and parts, except using four servo motors, all other power supplies all adopt the air supply output, and the electrical components and the heating element that use all adopt 24v safe voltage for this equipment has advantages such as occupation of land space is little, compact structure, the maintenance of being convenient for. Particularly, the equipped TPC control system does not need programming and is convenient to operate, and all control programs from feeding to finished products are completed by one machine, so that the equipment is full-automatic mechanical equipment for manufacturing and processing disposable edible meal boxes by taking pure natural wood veneers as raw materials.
The material 73 that this equipment adopted when preparation cutlery box is the wood skin, but is not limited to the wood skin, and this equipment also can use the material of other materials to carry out the production of cutlery box.
The shape of the lunch box manufactured by the equipment is ship-shaped but not limited to ship-shaped, and the shape of the inner mold 85 of the inner mold molding component 19 can be changed according to the requirement; the arrangement of the pushing cylinder and the push rod of the external mold driving device 20; the shapes of the outer die folded plate 86 and the manipulator of the outer die forming mechanism 79, the cutting position of the notch of the material 73 and the like.
