The double-layer blister product includes a double-layer blister tray, a cover of a surrounding plate box, a bottom of the surrounding plate box, a surrounding plate of the surrounding plate box, a circulating package or an automobile air pipe, and the like. Taking the double-layer blister tray as an example, the double-layer blister tray for loading, stacking, carrying and transporting goods can greatly improve the logistics efficiency. Commonly used trays are mainly made of wood. With the increasing demand for logistics, the double-layer blister tray has gradually been applied. In the prior art, the double-layer blister tray processing equipment is usually provided with a left extruder and a right extruder, and the left plastic sheet and the right plastic sheet are respectively cut and transported to the upper die and the lower die of the press machine through a left trolley and a right trolley, and finally the double-layer blister tray is formed by fusion. Since the double-machine extrusion mode of the left extruder and the right extruder has the problems of large equipment, large occupied area, low utilization rate and high power consumption, the processing cost of the double-layer blister tray is increased. SUMMARY

[0003] In view of the above problems, the application provides a processing method of a single-machine one-step double-layer blister processing equipment, which integrates the double-machine extrusion mode of the left extruder and the right extruder into a single-machine extrusion mode.

[0004] The technical scheme of the application is as follows:

[0005] The processing method of the single-machine one-step double-layer blister processing equipment comprises the following steps:

[0006] S1. Plastic raw materials are plasticized by an extruder, extruded into plastic sheets through a flat die at high temperature, and laid on an upper conveying belt;

[0007] S2. A cutting device cuts the plastic sheets on the upper conveying belt into upper plastic sheets and lower plastic sheets according to a predetermined length;

[0008] S3. The upper conveying belt conveys the cut upper plastic sheets and lower plastic sheets to a lower conveying belt of a lower transfer mechanism and a receiving mechanism of an upper transfer mechanism, respectively;

[0009] S4. The upper plastic sheets are conveyed by the upper transfer mechanism into a die combining device and lifted by the receiving mechanism into an upper die of the die combining device, and are adsorbed in the upper die by negative pressure generated;

[0010] S5. The lower plastic sheet is conveyed to the mold closing equipment by the lower transfer mechanism. It is conveyed to the lower mold by the movement of the lower transfer mechanism and the rotation of the lower conveyor belt, and is adsorbed onto the lower mold by the generated negative pressure.

[0011] S6. The upper and lower molds of the mold closing equipment are closed, the upper and lower plastic sheets are fused together, and a partial hollow is formed by air injection and pressure holding;

[0012] S7. After cooling, release the pressure and demold to form the double-layer thermoformed product.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] The upper and lower plastic sheets are processed using only one extruder, which greatly simplifies the equipment; it has a small footprint and low power consumption; it shortens the processing time; and it has added reinforcing parts to improve strength.

[0026] The application will be further described in conjunction with the accompanying drawings:

[0027] The application discloses a processing method of a single-machine one-step double-layer blister processing equipment, and embodiment 1 comprises the following steps:

[0028] S1. Plastic raw materials are plasticized by an extruder, extruded into plastic sheets at high temperature through a flat die head, and laid on an upper conveying belt 30;

[0029] S2. A cutting device 11 cuts the plastic sheets on the upper conveying belt 30 into upper plastic sheets and lower plastic sheets according to a predetermined length;

[0030] S3. The upper conveying belt 30 conveys the cut upper plastic sheets and lower plastic sheets to a lower conveying belt 60 of a lower transfer mechanism 5 and a receiving mechanism 28 of an upper transfer mechanism 2 respectively;

[0031] S4. The upper plastic sheets are conveyed by the upper transfer mechanism 2 into a die combining device 8 and lifted by the receiving mechanism 28 into an upper die 81 of the die combining device 8, and are adsorbed in the upper die 81 by negative pressure generated by air ports of the upper die 81;

[0032] S5. The lower plastic sheets are conveyed by the lower transfer mechanism 5 into the die combining device 8, conveyed to a lower die 82 under the movement of the lower transfer mechanism 5 and the rotation of the lower conveying belt 60, and are adsorbed on the lower die 82 by negative pressure generated by air ports of the lower die 82;

[0033] S6. The upper die 81 and the lower die 82 of the die combining device 8 are combined, the upper plastic sheets and the lower plastic sheets are fused into one, and local hollows are formed by gas injection and pressure maintaining;

[0034] S7. After cooling, the pressure is released and the die is demolded, forming double-layer blister products.

[0035] In embodiment 2, on the basis of embodiment 1, in step S3, the reinforcing piece placing mechanism on the upper transfer mechanism 2 can clamp the reinforcing piece 76 by a mechanical hand;

[0036] After step S5, the mechanical hand places the reinforcing piece 76 on a predetermined position of the lower plastic sheet.

[0037] Before step S3, the reinforcing piece conveying mechanism 7 previously conveys the reinforcing piece 76 from outside the processing equipment into the processing equipment, and the reinforcing piece placing mechanism clamps the reinforcing piece 76 from the reinforcing piece conveying mechanism 7.

[0038] In embodiment 3, on the basis of embodiment 1 and embodiment 2, two sets of single-machine one-step double-layer blister processing equipment are arranged, and each step of the two sets of equipment is completed alternately.

[0039] The single-machine one-step double-layer blister processing equipment involved in the embodiments is, for example, Figure 1 andFigure 2 As shown, comprising:

[0040] A mold closing device 8 is installed with an upper mold 81 and a lower mold 82 for forming a double-layer blister product;

[0041] An extruder 1 is capable of continuously extruding plastic sheets at high temperature;

[0042] A cutting device 11 is fixed at the outlet of the extruder 1, when the plastic sheet extruded by the extruder 1 reaches a predetermined length, a cutter in the cutting device 11 can cut the plastic sheet;

[0043] An upper conveying device 3 is provided with an upper conveying belt 30 capable of receiving the cut plastic sheet, each double-layer blister product is provided with two plastic sheets, which are an upper plastic sheet and a lower plastic sheet respectively;

[0044] An upper transfer mechanism 2 is provided with an upper walking mechanism and a receiving mechanism 28, the upper walking mechanism is capable of moving back and forth along two upper guide rails 41, the receiving mechanism is capable of receiving the upper plastic sheet sent out by the upper conveying device 3, lifting and sending the upper plastic sheet into the upper mold 81 of the mold closing device 8 and being vacuum adsorbed by the upper mold 81;

[0045] A lower transfer mechanism 5 is provided with a lower walking mechanism capable of moving back and forth along two lower guide rails 51, which are located below the upper guide rails 41;

[0046] A lower conveying device 6 is fixed on the lower transfer mechanism 5, when the lower transfer mechanism 5 moves towards the mold closing device 8, a lower conveying belt 60 of the lower conveying device 6 can receive the lower plastic sheet output from the upper conveying belt 30 of the upper conveying device 3, when the lower transfer mechanism 5 moves into the mold closing device 8, the lower conveying belt 60 moves following the lower transfer mechanism 5 while rotating, and can send the lower plastic sheet to the lower mold 82 of the mold closing device 8;

[0047] The upper mold 81 of the mold closing device 8 can move downwards to close with the lower mold 82 under the action of an oil cylinder, the upper plastic sheet in the upper mold 81 and the lower plastic sheet in the lower mold 82 are fused into one, and through air injection pressure maintaining, a local hollow is formed, after cooling, the pressure maintaining is released and demolding, forming a double-layer blister product;

[0048] A controller controls each electric appliance to complete the processing action according to the predetermined program.

[0049] It should be noted that, since the size of some products, such as double-layered blister trays, is usually several square meters and needs a certain thickness, more plastic is needed, and the speed of the plastic extruder 1 is relatively slow when extruding the plastic sheet, so the prior art with double-machine structure, although two sets of extruders are used to work simultaneously, the processing speed is still difficult to increase; in the present application, since the upper conveying device 3 is fixed in position and can continuously receive the plastic sheet output by the extruder 1, the upper conveying device 3 has a storage function, and this structure significantly improves the efficiency and shortens the waiting time during extrusion, in addition, the upper conveying device 3 can quickly transfer the plastic sheet to the lower conveying belt 60 or the receiving mechanism 28 of the upper transfer mechanism 2, so the overall time is shortened.

[0050] It should also be noted that, when the upper plastic sheet and the lower plastic sheet are extruded from the extruder 1, it is the temperature at which the plastic is melted, and the upper plastic sheet in the upper mold 81 and the lower plastic sheet in the lower mold 82 can be fused together.

[0051] The present application uses only one extruder 1 to complete the processing of the upper plastic sheet and the lower plastic sheet by setting the upper conveying device 3 and the lower conveying device 6, greatly simplifying the equipment, since the extruder 1 is large in size, occupies a large area, and consumes a lot of electricity, the single-machine structure of the present application significantly reduces the equipment cost, reduces the occupied area, and also significantly reduces the energy consumption and shortens the processing time.
