[0002] Plastic packaging is a box made of plastic as the main material and used to package goods. Compared with some other packaging materials (such as glass and metal), the production cost of plastic is relatively low and it can be produced on a large scale, which makes plastic packaging boxes have certain price advantages. Among them, blister packaging is usually a kind of packaging box that is formed by heating and softening plastic sheets and then using a mold to blister. This kind of packaging box is transparent, beautiful, and has a strong three-dimensional effect. It is often used to package food, toys, electronic products, etc.

[0003] The utility model application number 201922083843.3 discloses a blister device for producing plastic packaging boxes.

The device has high production efficiency and a high degree of automation, and is worthy of promotion.

[0004] However, in the above-mentioned blister forming device for producing plastic packaging boxes, the transmission belt is easily damaged when the heater and the heating block heat the plastic sheet, and the blister forming operation cannot be performed during heating, which easily affects the production efficiency. After the blister forming is completed in the above-mentioned blister forming device for producing plastic packaging boxes, the blister formed plastic packaging boxes still need to be cut out manually, so that the processing efficiency is affected by the labor efficiency.

[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0019] according to Figure 1 、 Figure 2 、 Figure 3As shown, this embodiment provides a three-station blister forming integrated machine for packaging boxes, including a workbench 1, a bracket 2, a first electric telescopic rod 3, a mold clamping bin 4, a stretching feeding mechanism, a heating mechanism, a blister mechanism and a cutting mechanism. The bracket 2 is fixed on the workbench 1, and the first electric telescopic rod 3 is symmetrically fixed on the top of the bracket 2 and on both sides below the workbench 1. A mold clamping bin 4 is fixed between the telescopic ends of the first electric telescopic rod 3. The stretching feeding mechanism includes a roll-off rack 5, a stretching roller 6, a transmission shaft 7, a motor 8 and a guide chute 9. The roll-off rack 5 is symmetrically fixed on one side of the bracket 2, and the stretching roller 6 is symmetrically rotated on the other side of the bracket 2. A transmission shaft 7 is fixedly connected between the stretching rollers 6. A motor 8 is fixed on the front of the other side of the bracket 2. Two groups of stretching rollers 6 are symmetrically arranged up and down, and the motor 8 outputs The end is driven and connected to a group of stretching rollers 6, and a guide slide groove 9 is fixed in the middle of the front and back of the bracket 2. A heating mechanism is provided on one side of the mold bin 4, a blister mechanism is provided in the middle of the mold bin 4, and a cutting mechanism is provided on the other side of the mold bin 4. When the packaging box is blister processed, the plastic coil is placed on the unwinding rack 5, and the plastic coil is pulled out from between the stretching rollers 6 after stretching. During the blister processing, the motor 8 drives the stretching roller 6 to frictionally drive the plastic coil to move, unwind and unfold, effectively improving the continuous processing capacity. Each time the mold bin 4 is opened, the stretching roller 6 pulls the edge of the plastic material to move and drive the plastic coil to enter the next process. When blistering is performed, the first electric telescopic rod 3 is reciprocated to drive the mold bin 4 to move and close the mold, which is convenient for multiple workstations in the mold bin 4 to perform heating, blistering and cutting in sequence, effectively improving production efficiency.

[0020] The heating mechanism includes a heating groove 10, an electric heating pipe 11 and a ventilation hole 12. A heating groove 10 is provided on one side of the mold closing chamber 4. Electric heating pipes 11 are arranged and fixed in the heating groove 10. Ventilation holes 12 are provided on one side of the mold closing chamber 4. When the electric heating pipe 11 is energized and heated before blister forming, the plastic coil is heated and softened when the mold closing chamber 4 is closed, which facilitates rapid blister forming.

[0021] The blister mechanism includes a blister groove 13, a diverter pipe 14, a through groove 15, a vacuum pump 16 and a corrugated hose 17. A blister groove 13 is provided in the middle of the mold chamber 4, and a diverter pipe 14 is provided below the lower blister groove 13. A through groove 15 is provided in the middle of the workbench 1, and a vacuum pump 16 is provided below the middle of the workbench 1. A corrugated hose 17 is fixed above the vacuum pump 16. The upper end of the corrugated hose 17 passes through the through groove 15 and is fixedly connected to the middle of the lower mold chamber 4, and the corrugated hose 17 is connected to the diverter pipe 14. When blistering is performed, the vacuum pump 16 starts to exhaust air when the mold chamber 4 is closed, and the air is diverted and exhausted by the corrugated hose 17 and the diverter pipe 14, so that the blister effect is more uniform.

[0022] The cutting mechanism includes a cutting groove 18, a second electric telescopic rod 19, a top block 20, a cutting grid 21, a limiting grid 22, a material discharge port 23 and a material receiving box 24. The other side of the mold clamping bin 4 is equipped with a cutting groove 18, and the other side of the upper mold clamping bin 4 is fixed with a second electric telescopic rod 19. A top block 20 is provided in the upper cutting groove 18, and a cutting grid 21 is fixed below the top block 20. A limiting grid 22 is fixed in the lower cutting groove 18. A material discharge port 23 is provided on the other side of the workbench 1. A material receiving box 24 is provided at the lower part of the other side. The output end of the second electric telescopic rod 19 is fixedly connected to the top block 20. The lower part of the other side of the mold closing chamber 4 is opened. After the blister forming is completed, the plastic material is moved to the corresponding position of the cutting groove 18 by the stretching roller 6. When the mold closing chamber 4 is closed, the cutting grid 21 and the limiting grid 22 cooperate to cut the formed packaging box from the whole. Then, the second electric telescopic rod 19 extends to drive the top block 20 to descend, push the packaging box down, and freely fall into the material receiving box 24 through the discharge port 23.

[0023] When the three-station blister forming machine for packaging boxes is working, the plastic coil used as the blister material is placed on the unwinding rack, the plastic coil is pulled out to the other side of the workbench and passes between the stretching rollers. The guide slide guides the plastic coil to move. When the molding process is being carried out, the first electric telescopic rod reciprocates to drive the mold closing chamber. When the mold closing chamber is opened, the motor drives the stretching roller to rotate and drive the plastic coil to move by friction, thereby realizing continuous blister processing. Before the blister processing is carried out, the electric heating tube is energized to heat it. When the mold closing chamber is closed, the plastic coil loaded into the heating chamber is heated. The mold is heated and softened, and then the first electric telescopic rod drives the mold chamber to open, and the stretching roller rotates and pulls the softened plastic to the corresponding position of the blister groove. After the mold is closed again, the vacuum pump is started to evenly blister through the corrugated hose and the diverter pipe. After that, the mold chamber is opened again, and the stretching roller rotates and pulls the molded plastic to the corresponding position of the cutting groove. When the mold chamber is closed, the cutting grid and the limit grid cooperate to cut the formed packaging box and the plastic residue. The second electric telescopic rod extends to drive the top block to descend, and the packaging box is pushed down and freely falls into the receiving box through the discharge port.
