[0002] Aluminium -plastic blister packaging machine is a kind of plastic sheet is formed into blister first, then fills material in blister, and blister is heat-sealed film equipment again.Aluminium -plastic blister packaging machine is widely used in the packaging of drug, and its temperature is higher in working process due to heating plastic sheet, heat-sealing and other procedures, so aluminium -plastic blister packaging machine needs to be cooled.

[0003] Traditional aluminium -plastic blister packaging machine cooling mode is directly using tap water direct cooling, i.e., tap water is connected by water pipe forming lower mould cooling plate, guide rail cooling plate, heat-sealing lower mould cooling plate, heat-sealing cylinder base cooling plate.Manual valve is set on water pipe, and cooling speed is adjusted by manual valve by artificial adjustment.This cooling mode has the following shortcomings:

[0004] (1) cooling effect is poor, and valve is opened manually by operator, and since there is no quantitative water consumption, cooling effect has great uncertainty.

[0005] (2) water resource is wasted, and water consumption is adjusted by subjective consciousness of operator, so unnecessary waste of water resource is easily caused.

[0006] (3) there is quality risk, and since external environment temperature is influenced, water tank temperature is increased with high temperature weather, and equipment cooling effect is reduced with high temperature weather, so PVC plate and aluminium film are easily deformed, wrinkled and crushed.

[0007] (4) there is safety risk, and since cooling effect is poor, operator needs to adjust work station mould and packaging material frequently, so scalding is easily caused by colliding with mould.

[0008] (5) production efficiency is low, and since cooling effect is poor, high-speed production cannot be adopted, production speed is slowed down, so production efficiency is low, and production benefit is reduced.

[0009] (6) production cost is high, and since PVC forming and aluminium film mould cooling are not timely in production process, stroke traction is not matched, so material loss is easily caused, and production cost is increased. UTILITY MODEL CONTENTS

[0030] It should be noted that, unless otherwise specified, the relative arrangement of components and steps, numerical expression set forth in these embodiments should not be understood as limiting the scope of the utility model.

[0031] The following description of exemplary embodiments is merely illustrative in nature, and is not in any way limiting on the scope of the utility model and its applications or uses. Here, the technology, methods and devices known to those of ordinary skill in the related art can not be discussed in detail, but in the case of applying these technology, methods and devices, these technology, methods and devices should be regarded as part of the specification.

[0032] Example 1

[0033] This embodiment provides a cooling device, such as... Figure 1 As shown, the system includes a chiller unit, which includes a water tank 1. A coil 2 is installed around the water tank 1, and the coil 2 contains coolant. The coil 2 is connected to a compressor 3. The water tank 1 is connected to a water supply pipe 4, an inlet pipe 5, and an outlet pipe 6. The inlet pipe 5 and the outlet pipe 6 are connected to the component to be cooled.

[0034] The coolant in coil 2 is water, and coil 2 can be configured in a spiral shape, surrounding water tank 1. The compressor 3 cools the water in coil 2. When the low-temperature water in coil 2 passes through water tank 1, it exchanges heat with the water in water tank 1, thereby cooling the water in water tank 1. The cooled water in water tank 1 then cools the components being cooled.

[0035] To monitor the water level in water tank 1 in a timely manner, a level sensor 7, preferably a float level transmitter, is installed inside water tank 1. When the water level in water tank 1 falls below the set lower limit, water is replenished to water tank 1 through water supply pipe 4, which can be directly connected to tap water.

[0036] For ease of operation, a ball valve is installed on the water supply pipe 4, and / or a ball valve 8 is installed on the water inlet pipe 5, and / or a ball valve 8 is installed on the water outlet pipe 6. All ball valves 8 are manual valves. In other embodiments, the ball valves 8 may also be electric valves. In addition, a water pump 17 is installed on the water inlet pipe 5 to provide circulation power for the water in the water tank 1.

[0037] Furthermore, a temperature sensor 9 is installed inside the water tank 1. The temperature sensor 9 is connected to a control unit, which is connected to the compressor 3. The temperature sensor 9 is used to measure the water temperature inside the water tank 1. When the water temperature exceeds a set threshold of 3°C, the control unit starts the compressor 3. The compressor 3 cools the coolant in the coil 2, and the coolant then cools the water in the water tank 1 through heat exchange until the water temperature in the water tank 1 reaches or falls below the set threshold.

[0038] The chiller unit also includes a housing 10, in which the water tank 1, the coil 2, and the compressor 3 are all housed. An exhaust fan 11 is also installed above the housing 10 to exhaust the high-temperature gas inside the housing 10 and prevent heat buildup inside the housing 10.

[0039] A water guide plate 12 is provided below the box body 10 to collect condensate from the outer wall of the box body 10.

[0042] A first cooling pipe and a second cooling pipe are provided between the water inlet pipe 5 and the water outlet pipe 6. The first cooling pipe and the second cooling pipe are connected in parallel. The molding lower mold cooling plate 13 and the guide rail cooling plate 14 are connected in series on the first cooling pipe. The heat-sealing lower mold cooling plate 15 and the heat-sealing cylinder base cooling plate 16 are connected in series on the second cooling pipe.

[0043] After the aluminum-plastic blister packaging machine is powered on, the cooling device is activated, and the water in water tank 1 is circulated and cooled. When the water temperature in water tank 1 is higher than the set threshold by 3°C, the compressor 3 is started. The compressor 3 cools the water in coil 2. The cooled water in coil 2 then cools the water in water tank 1 through heat exchange. When the water temperature in water tank 1 reaches or falls below the set threshold, the compressor 3 stops. The cooled water in water tank 1 continues to circulate and cool.
