In order to rapidly cool and shape the bubble cap after heat sealing, as shown in fig. 1, the bubble cap cooling device 7 is arranged between the bubble cap heat sealing device 6 and the heat sealing traction device 8, as shown in fig. 2, the bubble cap cooling device 7 comprises a cooling box 70 and a cooling plate 71 (the cooling plate 71 is the prior art, a heat cooling pipe is arranged on the upper surface, water is filled in the heat cooling pipe to realize water cooling), the cooling plate 71 is arranged in the cooling box 70, and a cooling channel for the bubble cap to pass through is arranged below the cooling plate 71. After the bubble cap passes through the heat seal of the bubble cap heat sealing device, the bubble cap firstly enters a cooling box of the bubble cap cooling device, the bubble cap passes through a cooling channel below the cooling plate 71, the cooling plate 71 is attached to the bubble cap, and heat on the bubble cap is taken away, so that the bubble cap is rapidly cooled and shaped, then the bubble cap enters the heat seal traction device 8, and the bubble cap is cooled down, so that the heat seal traction device 8 cannot deform the bubble cap in the process of drawing the bubble cap.
In order to prevent the bubble cap heat sealing device 6 from influencing the PVC film in a stop state (high temperature can be generated between a heat sealing upper die and a heat sealing lower die of the bubble cap heat sealing device), the invention is provided with a guide shaft 73 in a cooling box 70, a moving seat 74 is arranged on the guide shaft 73 in a sliding way, a cooling plate 71 is connected on the moving seat 74, the moving seat 74 is in transmission connection with a cooling plate power source for driving the moving seat 74 to move back and forth, and the cooling plate 71 can be moved between the heat sealing upper die and the heat sealing lower die of the bubble cap heat sealing device 6 by the driving of the cooling plate power source. When the injection molding machine normally operates, the cooling plate 71 of the bubble cap cooling device 7 extends between the heat-sealing upper die and the heat-sealing lower die of the bubble cap heat-sealing device 6, so that the heat radiation of the bubble cap heat-sealing device 6 to the injection is blocked, and the product quality of the injection is ensured.
In order to make the bubble caps in the cooling box 70 always stick to the cooling plate 71, the bubble cap pallet 72 is arranged in the cooling box 70, the bubble cap pallet 72 is provided with a bubble tray guide groove 720 (the bubble caps are arranged in the bubble tray guide groove 720), and the bubble cap pallet 72 is positioned below the cooling plate 71. When the bubble cap enters the cooling box 70, the bubble cap enters the bubble cap supporting plate 72, and the bubble cap supporting plate 72 supports and positions the bubble cap, so that the bubble cap can be attached to the cooling plate 71 all the time, and a better cooling effect is achieved.
At present, most of existing foam tray forming devices adopt a cam mechanism form, a cam is in rolling friction contact with a roller at the bottom of a lower die, a motor reducer is connected with a spline shaft to drive the cam to rotate so as to change the up-and-down motion of a die for die assembly, when the cam rotates too fast, the roller of the lower die is separated from the contact with the cam, and when the cam is contacted with the roller of the lower die again, the cam can be in impact contact.
In order to solve the above problems, the present invention provides a novel foam tray forming apparatus 2. As shown in FIG. 4, the foam tray forming device comprises an upper mounting plate 29, a lower mounting plate 21, a guide post 22, an upper forming die 27 and a lower forming die 26, wherein the guide post 22 is mounted between the upper mounting plate 29 and the lower mounting plate 21, the lower forming die 26 is mounted on a lower forming die tray 24, the lower forming die tray 24 is slidably mounted on the guide post 22, in order to drive the lower forming die 26 to move upwards and to be matched with the upper forming die 27, a link transmission mechanism is provided between the lower forming die tray 24 and the lower mounting plate 21, as shown in FIG. 5 or FIG. 6, the link transmission mechanism comprises a middle link 211, an upper link 212 and a lower link 213, the lower end of the upper link 212 is hinged on the middle link 211, the upper end of the upper link 212 is hinged on the lower forming die tray 24, the upper end of the lower link 213 is hinged on the middle link 211, the lower end of the lower link 213 is hinged on the lower mounting plate 21, and the middle link 211 is hinged on a pull rod 217, as shown in fig. 7, the pull rod 217 is drivingly connected to the power source 215 for driving the pull rod 217.
The working principle is as follows: in operation, the power source 215 drives the pull rod 217 to move left and right, the pull rod 217 pulls the middle connecting rod 211 to move the middle connecting rod 211 left and right, the middle connecting rod 211 drives the upper connecting rod 212 and the lower connecting rod 213 to rotate synchronously by a certain angle, so that the lower molding die tray 24 moves up and down on the guide pillar 22 relatively, the lower molding die 26 is driven to move up and down, the upper molding die 27 is matched with the lower molding die when moving up, and the upper molding die 7 is opened when moving down. As the up-and-down movement of the lower molding die tray 24 is transmitted by the connecting rod transmission mechanism, the speed is higher and the operation is more stable.
As shown in fig. 5, the upper link 217 has two front and rear groups, two left and right groups, and the lower link 213 has two front and rear groups, two left and right groups. The multi-group connecting rod has the following advantages: when the upper and lower opening and closing die moves, the two groups of connecting rods are used, force in tandem acts on the lower forming die tray 24, so that the parallelism is better, the rising stability is higher, the upper and lower die films are laminated more, the requirement on the structural manufacturing precision is reduced, and the service life is longer. Compared with the prior art, the upper die and the lower die are jacked by the rotation of the cam, the force applied to the lower forming die tray is the tangential force of the rotation of the cam, the cam is in linear contact with the roller of the lower forming die tray, so the cam cannot rise in a balanced manner, the cam is positioned forcibly by the guide post guide sleeve to rise linearly, the requirements on the strength and the precision of the guide post guide sleeve are extremely high, and the output torque of the cam is correspondingly increased in order to enable the cam to rise rapidly.
As shown in fig. 7, the power source 215 of the present invention is a servo motor, the servo motor 215 is connected with the axle of an eccentric wheel 216, and the eccentric wheel 216 is connected with a pull rod 217 through a bearing. Because the device adopts the connecting rod transmission mechanism, the pressure of die assembly is decomposed, and the load is prevented from being directly acted on the wheel shaft of the eccentric wheel 216. When the pressure for closing the dies is a constant value, the torque of the axle of the driving eccentric wheel 216 is reduced by times when the lower forming die 26 is closer to the upper forming die 27, when the bubble blowing work is performed in the die, the upper connecting rod 212 and the lower connecting rod 213 are both in a vertical state, the upper connecting rod 212 and the lower connecting rod 213 bear the internal force at the moment, and the torque output by the servo motor is relatively zero, so that the torque output by the servo motor is reduced, the servo motor can output a higher rotating speed, and the operating speed for opening and closing the dies is improved.
In order to offset the inertia, the invention connects a buffer part (such as a spring, a gas spring and the like) between the lower molding die tray 24 and the lower mounting plate 21, the buffer part of the invention specifically adopts a buffer cylinder 214, and the vibration generated by the inertia can be effectively eliminated by adjusting the air pressure and the exhaust speed of the buffer cylinder 214, so that the machine can run more stably. Compared with the prior art, cam mechanism utilizes the roller rolling friction contact of cam and shaping lower mould to realize the up-and-down motion, the rotational speed of cam is greater than the shaping lower mould and falls to the acceleration, cam and shaping lower mould roller break away from this moment, the recontacting will strike, this condition is not allowed to exist at this in-process of normal operating, so the cam rotational speed just can not be too fast, can only be at low-speed work, secondly when shaping lower mould and shaping upper mould are more close, the moment of torsion of output is bigger and bigger, when the inside bubble blowing work that carries out of mould, the moment of torsion of output reaches the maximum value, so there is higher requirement to servo motor's output moment of torsion.
In order to provide a buffering effect between the upper mold 26 and the lower mold 27 during mold clamping, the upper mold 27 is mounted on the upper mold mounting plate 28, the buffer 210 is mounted on the upper mounting plate 29, and the buffer 210 is connected to the upper mold mounting plate 28. The buffer 210 is a spring in the prior art, and can effectively slow down the impact generated when the upper forming die 27 and the lower forming die 26 are closed through the buffering of the spring, so that the closing noise is reduced, the closing is more stable, and the service life is longer.
In order to cool the lower mold 26, the present invention mounts the lower mold 26 on the cooling water plate 25, and the cooling water plate 25 on the lower mold tray 24. The cooling water plate 25 can quickly cool the bubble tray, so that the bubble tray is not deformed when the forming traction device 8 draws the bubble tray.
The blister punch cutting device 9 is an important station in blister packaging machines and functions to punch individual blisters from a continuous blister sheet that has been sealed, and then to lower the blisters onto a blister grid conveyor from which the blisters are fed to a cartoning machine for cartoning. The existing bubble cap punching device comprises a punching female die, a punching convex film and a punching power source, the punching female die and the punching convex film are driven to be matched with each other through the punching power source, a bubble cap is punched from a continuous bubble cap plate, the bubble cap falls onto a grid conveying device, and the bubble cap is continuously conveyed forwards through the grid conveying device. However, a certain fall exists between the bubble cap punching point and the grid conveying device, and the bubble cap may bounce when directly falling down and cannot accurately enter the grid of the grid conveying device, so that subsequent work cannot be normally carried out.
