Description

Technical Field

[0001] This application relates to the technical field of bottle-making mold processing, and particularly to a cooling circulation device for a bottle-making machine. Background Art

[0002] In the pharmaceutical glass manufacturing industry, for bottle-making machines such as ampoule bottle-making machines and vial bottle-making machines, during the production of pharmaceutical glass bottles, a cooling circulation device is required to cool down the forming molds in the bottle-making machines. The working principle of this cooling circulation device is that cooling water is pumped by a water pump from the cooling tank into each bottle-making machine for cooling. After the cooling is completed, the cooling water in each bottle-making machine flows back to the buried return water main pipe through each return water branch pipe, and then returns to the cooling tank through the buried return water main pipe, and then is pumped into each device by the water pump, so as to circulate. For example, the application number is 202021599999.3, and the name is a water jacket type bottle-making machine material flow device.

[0003] In some prior arts, the buried return water main pipe used in the pharmaceutical glass bottle-making production workshop has a long pipeline and almost the same height, which makes the cooling water unable to completely flow back to the cooling tank, resulting in the problem of liquid deposition in the return water main pipe. Over time, scale is likely to deposit on the inner wall of the water pipe. The existence of scale will affect the water flow smoothness and also cause the water quality to deteriorate, thus affecting the working environment. Summary of the Utility Model

[0004] One technical problem to be solved by this application is: the liquid flow of the cooling circulation device for a bottle-making machine is not smooth.

[0005] To solve the above technical problem, a cooling circulation device for a bottle-making machine according to an embodiment of this application includes: a cooling tank, which is connected to the water inlet pipe of the cooling structure of the bottle-making machine through a circulating water cooling structure; a plurality of interconnected return water main pipes, one end of any return water main pipe is connected to the cooling tank, the length direction of the return water main pipe has a certain preset angle with the horizontal direction, and the end of the return water main pipe close to the cooling tank is lower than the other end; a plurality of return water branch pipes, all return water branch pipes are connected to the return water pipe of the cooling structure of the bottle-making machine; a plurality of connecting pipes, which are arranged at intervals along the length direction of the return water main pipe and are arranged in one-to-one correspondence with the return water branch pipes. The first end of the connecting pipe is connected to the return water main pipe, and the second end of the connecting pipe is connected to the return water branch pipe. At least part of the connecting pipe is located below the ground, and the return water branch pipe is located above the ground.

[0006] In some embodiments, the preset angle is specifically 2% to 5%.

[0007] In some embodiments, there are specifically two return water main pipes, and one end of any one of the return water main pipes extends into the cooling tank, and the extended end is connected to the other return water main pipe.

[0008] In some embodiments, the return water branch pipe is U-shaped and includes a horizontal pipe and vertical pipes provided at both ends of the horizontal pipe. The horizontal pipe communicates with the connecting pipe, and both ends of the vertical pipes communicate with the horizontal pipe and the outlet of the cooling structure of the bottle making machine respectively.

[0009] In some embodiments, it further includes: an outlet regulating valve provided at one end of the return water main pipe located in the cooling tank for regulating the flow rate of the cooling water in the return water main pipe.

[0010] In some embodiments, it further includes: an inlet check valve provided on each return water branch pipe for preventing the cooling water from flowing back into the cooling structure of the bottle making machine; an inlet regulating valve spaced from the inlet check valve on each return water branch pipe for regulating the flow rate of the cooling water in the return water branch pipe.

[0011] In some embodiments, the connecting pipe is vertically provided between the return water main pipe and the return water branch pipe.

[0012] In some embodiments, it further includes: a purging assembly provided at one end of all the return water main pipes away from the cooling tank, and each return water branch pipe is located between the purging port of the return water main pipe and the cooling tank of the return water main pipe.

[0013] In some embodiments, the purging assembly includes: an air pipe, one end of the air pipe is connected to an external pressurization system, and the other end is communicated with the return water main pipe; a pneumatic valve installed on the air pipe.

[0014] In some embodiments, it further includes: a controller electrically connected to the pneumatic valve, the outlet regulating valve, the inlet check valve and the inlet regulating valve to control the opening and closing of the pneumatic valve, the outlet regulating valve, the inlet check valve and the inlet regulating valve.

[0015] In the prior art, the return water branch pipe is directly connected to the return water main pipe. When the return water main pipe is inclined and arranged in the ground, the return water branch pipe will also be inclined under the interference of the return water main pipe, thereby increasing the installation difficulty of the return water branch pipe and reducing the flow rate of the cooling water. However, the technical solution of the present application adds a connecting pipe, which is arranged between the return water main pipe and the return water branch pipe, and can effectively solve the interference problem of the return water main pipe on the return water branch pipe, ensure that the return water branch pipe is straightened and in a horizontal state, reduce the floor area of the buried pipe, and better ensure that when the return water main pipe is pre-buried and poured, the return water main pipe maintains a certain slope in the direction of the cooling tank, so that the cooling water flows back more smoothly and avoids poor liquid circulation in the pipeline. The technical solution of the present application effectively solves the problem of poor liquid circulation in the cooling circulation device for bottle making machines in the prior art.

[0026] Technologies, methods and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, the technologies, methods and devices should be regarded as part of the specification.

[0027] As Figure 1 shown, a cooling circulation device for a bottle making machine provided by some embodiments includes: a cooling box 10. The cooling box 10 is connected to the water inlet pipe of the cooling structure of the bottle making machine through a circulating water cooling structure. A plurality of mutually connected return water main pipes 20, one end of any one of the return water main pipes 20 is connected to the cooling box 10, the length direction of the return water main pipe 20 has a certain preset angle with the horizontal direction, and the end of the return water main pipe 20 close to the cooling box 10 is lower than the other end. A plurality of return water branch pipes 30, all the return water branch pipes 30 are connected to the return water pipe of the cooling structure of the bottle making machine. A plurality of connecting pipes 40 are arranged at intervals along the length direction of the return water main pipe 20 and are arranged in one-to-one correspondence with the return water branch pipes. The first end of the connecting pipe 40 is connected to the return water main pipe 20, the second end of the connecting pipe 40 is connected to the return water branch pipe, at least part of the connecting pipe 40 is located below the ground, and the return water branch pipe is located above the ground.

[0028] In some embodiments, the return water branch pipe is directly connected to the return water main pipe. When the return water main pipe is disposed obliquely in the ground, the return water branch pipe will also be inclined under the interference of the return water main pipe, which increases the installation difficulty of the return water branch pipe and reduces the flow rate of the cooling water. The technical solution of the present application adds a connecting pipe, which is disposed between the return water main pipe and the return water branch pipe, and can effectively solve the interference problem of the return water main pipe on the return water branch pipe, ensure that the return water branch pipe is straightened and in a horizontal state, reduce the floor area of the buried pipe, and better ensure that when the return water main pipe is pre-buried and poured, the return water main pipe maintains a certain slope in the direction of the cooling tank, so that the cooling water flows back more smoothly and avoids poor liquid circulation in the pipeline. The technical solution of the present application effectively solves the problem of poor liquid circulation in the cooling circulation device used in the bottle making machine in the prior art. It should be noted that the cooling tank is lower than the lowest end of the return water main pipe. By providing the connecting pipe 40, the return water branch pipe 30 is located above the ground. When the return water branch pipe 30 is connected to the cooling structure of the bottle making machine, the connection error can be compensated by moving the return water branch pipe 30, which facilitates the connection between the return water branch pipe 30 and the cooling structure of the bottle making machine. The above structure solves the problem that it is difficult to connect the return water branch pipe 30 with the cooling structure of the bottle making machine.

[0029] As Figure 1 shown, in the technical solution of some embodiments, the preset angle is specifically two percent to five percent. In this way, the fluidity of the coolant is relatively good. In the technical solution of this embodiment, the preset angle is three percent, that is, in the direction from far away from the cooling tank 10 to close to the cooling tank 10, the return water main pipe 20 gradually decreases, and the inclination angle with the horizontal plane is three percent.

[0030] As Figure 1 shown, in some embodiments, the return water main pipe 20 is specifically two. One end of any one of the return water main pipes 20 extends into the cooling tank 10, and the extended end is communicated with the other return water main pipe 20. The two return water main pipes 20 can not only increase the cooling branch, but also facilitate control. For example, if there are 6 return water main pipes 20, the return water is not easy to control, that is, there are short-circuit situations in some branches.

[0031] As Figure 1 shown, in some embodiments, the return water branch pipe 30 is in a U shape, including a horizontal pipe and vertical pipes provided at both ends of the horizontal pipe. The horizontal pipe is communicated with the connecting pipe 40, and both ends of the vertical pipes are respectively communicated with the horizontal pipe and the outlet of the cooling structure of the bottle making machine. The connecting pipe 40 is located in the middle of the horizontal pipe, so that the valve openings of the two vertical pipes are easy to control. The return water branch pipe 30 is in a U shape, and one connecting pipe 40 can correspond to two water outlets of the cooling structure of the bottle making machine.

[0032] As Figure 1As shown, in some embodiments, the cooling circulation device for a bottle making machine further includes: a water outlet regulating valve 50. The water outlet regulating valve 50 is provided at one end of the return water main pipe located inside the cooling tank 10, and is used to regulate the flow rate of the cooling water in the return water main pipe 20. The setting of the water outlet regulating valve 50 facilitates the regulation of the water output of the return water main pipe 20.

[0033] As Figure 1 shown, the cooling circulation device for a bottle making machine further includes: a water inlet check valve 60. The water inlet check valve 60 is provided on each return water branch pipe 30, and is used to prevent the cooling water from flowing back into the cooling structure of the bottle making machine. This can prevent the cooling water from flowing back, affecting the production of the bottle making machine and even damaging the bottle making machine. The cooling circulation device for a bottle making machine further includes: a water inlet regulating valve 70. The water inlet regulating valve 70 and the water inlet check valve 60 are spaced apart on each return water branch pipe 30, and are used to regulate the flow rate of the cooling water in the return water branch pipe 30. By adjusting each water inlet regulating valve 70, the flow rate in each return water branch pipe 30 can be controlled. On the one hand, this can prevent the situation where there is no liquid in some return water branch pipes 30. On the other hand, the flow rate and flow volume of each return water branch pipe 30 can be adjusted according to needs, so as to better exchange heat with the bottle making machine.

[0034] As Figure 1 shown, in some embodiments, the connecting pipe 40 is vertically provided between the return water main pipe 20 and the return water branch pipe 30. The vertical setting of the connecting pipe 40 is convenient for use and installation on the one hand, and the return water flows more smoothly through the connecting pipe 40 on the other hand.

[0035] As Figure 1 shown, in some embodiments, the cooling circulation device for a bottle making machine further includes: a purging assembly. The purging assembly is provided at one end of all the return water main pipes 20 away from the cooling tank, and each return water branch pipe 30 is located between the purging port of the return water main pipe 20 and the cooling tank 10 of the return water main pipe 20. This can maximize the purging distance. When the purging assembly purges, it adopts the form of a shock wave, that is, the pressure is relatively high for a period of time and the pressure decreases for a period of time. In this way, the liquid can be blown out when the pressure is high, and the liquid in some return water branch pipes 30 can flow back to the return water main pipe 20 when the pressure is low, so that the purging is cleaner.

[0036] As Figure 1 shown, in some embodiments, the purging assembly includes: an air pipe 81 and a pneumatic valve 82. One end of the air pipe 81 is connected to an external pressurization system, and the other end is communicated with the return water main pipe 20. It is installed on the air pipe 81. The external pressurization system includes a compressor and a buffer tank. The compressor is connected to the air pipe 81 through the buffer tank, so that the air volume is relatively uniform and easy to control when purging with air.

[0037] As Figure 1As shown, in some embodiments, the cooling circulation device for a bottle making machine further includes: a controller. The controller is electrically connected to the pneumatic valve 82, the water outlet regulating valve 50, the water inlet check valve 60, and the water inlet regulating valve 70, and controls the opening and closing of the pneumatic valve 82, the water outlet regulating valve 50, the water inlet check valve 60, and the water inlet regulating valve 70. The setting of the controller facilitates automatic control, and has the advantages of accurate control, time saving and labor saving.

[0038] It should be noted that, in some embodiments, the cooling circulation device for a bottle making machine further includes: a plurality of temperature sensors. Temperature sensors are arranged on both of the two return water main pipes 20, a temperature sensor is arranged in the cooling tank 10, and temperature sensors are arranged on each return water branch pipe 30. Each temperature sensor is electrically connected to the controller. By setting the temperature threshold value in the controller, the controller realizes automatic control of the above-mentioned valves, which further improves the precise control of the heat exchange of the bottle making machine by the cooling circulation device. The cooling circulation device further includes a display, and the display can display the temperatures of each temperature sensor.

[0039] It should be noted that when the above-mentioned compressed air is purged, the general pressure is controlled between 0.5 Mpa and 0.8 Mpa, and the height of the connecting pipe 40 is between 2.5 cm and 7 cm. In this embodiment, it is set between 3 cm and 5 cm.

In order to avoid obscuring the concept of the present application, some details well known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed here based on the above description.

[0041] Although some specific embodiments of the present application have been described in detail by way of examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the present application. Those skilled in the art should understand that the above embodiments can be modified or partial technical features can be equivalently replaced without departing from the scope and spirit of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in each embodiment can be combined in any way.
