Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing, and in particular to a pipe sealing machine. Background Technology

[0002] In fields such as biopharmaceutical and vaccine production, pipeline sealing is required, and current technology typically uses a sealing machine for this purpose. The sealing process involves first heating the pipeline with a heating device to melt it, then flattening, cooling, and shaping the melted portion to complete the seal. Therefore, the heating and heat dissipation efficiency of the sealing machine are the most important factors affecting its working efficiency.

[0003] Existing pipe sealing machines typically use relatively positioned heating elements to heat, melt, and clamp the pipes. However, due to limited internal space, a heat dissipation device (fan, air pump, etc.) is usually used for heat dissipation. This heat dissipation device is fixedly installed and uses pipes to transmit air. This structure results in significant air pressure loss and poor heat dissipation. Adopting a solution that increases airflow will significantly increase noise and may also cause vibration in the pipe sealing machine. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model discloses a tube sealing machine.

[0005] A pipe sealing machine includes a housing and a heating device disposed inside the housing. The heating device is used to melt and seal the pipe. The housing is also provided with a heat dissipation device for cooling the heating device.

[0006] The heat dissipation device includes a radiator fixed on the heating device, the heating device is provided with a heat dissipation channel for heat dissipation, and the housing is provided with ventilation holes; when the heating device is cooled, the heat dissipation channel is connected to the radiator and the ventilation holes.

[0007] Specifically, in the existing technology, when heat dissipating heat from a heating device, air is usually transmitted through pipes and then blown directly onto the heating device. Direct blowing has low heat dissipation efficiency, and the loss of air pressure during transmission leads to poor heat dissipation, meaning that the temperature of the heating device drops slowly. This results in a long time interval between two sealing operations, which seriously reduces the sealing efficiency of the sealing machine.

[0008] The solution provided by this utility model is to directly fix the radiator on the heating device, and at the same time, the radiator is connected to the heat dissipation channel provided on the heating device, and the heat dissipation channel is connected to the ventilation hole. That is, the air generated by the radiator directly enters the heat dissipation channel to dissipate heat from the heating device, and then the air is discharged through the ventilation hole. Good and directional air circulation can significantly accelerate the heat dissipation efficiency.

[0009] Preferably, the heating device includes a first heating module, a second heating module, and a driving device arranged opposite to each other, wherein the driving device is used to drive the first heating module and the second heating module to move closer to each other or further apart;

[0010] The radiator is a fan, and the fan includes two fans respectively fixed on the first heating module and the second heating module.

[0011] Specifically, since the first heating module and / or the second heating module are movable, the structure of directly fixing the fan to the first heating module and the second heating module ensures that the relative positional relationship between the fan and the first heating module and the second heating module remains unchanged. Therefore, regardless of the position or working state of the first heating module and the second heating module, high-efficiency and stable heat dissipation can be maintained.

[0012] Preferably, the first heating module includes a first fixing base and a first heating element that is detachably fixed on the first fixing base. The first fixing base is provided with a first groove, and a first heat dissipation channel is formed between the first groove and the first heating element.

[0013] The second heating module includes a second fixing base and a second heating element that is detachably fixed on the second fixing base. The second fixing base is provided with a second groove, and a second heat dissipation channel is formed between the second groove and the second heating element.

[0014] Specifically, in this structure, the positions of the first and second heat dissipation channels enable the fan to efficiently dissipate heat from the first and second heating elements, while also effectively reducing the weight of the entire sealing machine.

[0015] Preferably, the two fans are respectively fixed on the first fixed base and the second fixed base, and are respectively connected to the first heat dissipation channel and the second heat dissipation channel through the first connecting air duct and the second connecting air duct; the first connecting air duct is not connected to the second connecting air duct and the second heat dissipation channel; the first heat dissipation channel is not connected to the second connecting air duct and the second heat dissipation channel.

[0016] Specifically, in this structure, the first connecting air duct and the first heat dissipation channel form a heat dissipation channel for the first heating element only, and the second connecting air duct and the second heat dissipation channel form a heat dissipation channel for the second heating element only. The independent heat dissipation channels can achieve more efficient heat dissipation.

[0017] Preferably, the radial dimension of the first connecting air duct decreases towards the direction of the first heat dissipation channel, and the radial dimension of the second connecting air duct decreases towards the direction of the second heat dissipation channel;

[0018] The minimum radial dimension of the first connecting air duct is greater than the maximum radial dimension of the first heat dissipation channel;

[0019] The minimum radial dimension of the second connecting air duct is greater than the maximum radial dimension of the second heat dissipation channel.

[0020] Specifically, the structure in which air gradually enters the small-diameter first and second heat dissipation channels from the large-diameter first and second connecting air ducts can significantly reduce air pressure loss and improve the fan's heat dissipation efficiency.

[0021] Preferably, the housing is further provided with a support platform, the drive device is mounted on the support platform, and the support platform has a hollow structure; the housing is also provided with a number of reinforcing ribs, and the reinforcing ribs have a hollow structure.

[0022] Specifically, the hollowed-out support platform can significantly reduce the weight of the entire sealing machine on the one hand, and the multiple hollowed-out structures can make the gas circulation inside and outside the sealing machine smoother, which is more conducive to the cooling of the heating device.

[0023] The hollowed-out reinforcing ribs can significantly increase the stability of the components during operation of the sealing machine, without significantly increasing its weight.

[0024] Preferably, the housing is provided with a clearance section for the passage of a pipe, and the heating device seals the pipe at the clearance section. Preferably, it also includes a temperature sensor for real-time monitoring of the temperature of the heating device.

[0025] Specifically, during the operation of the pipe sealing machine, information such as whether the pipe has melted, whether it has been formed, and whether the heating device has cooled down to the point where it can be reused can all be obtained from the temperature of the heating device. Therefore, it is necessary to install a temperature sensor on the heating device.

[0026] Compared with the prior art, the advantages of this utility model are:

[0027] By directly fixing the radiator to the heating device, the distance between the radiator and the heating device remains constant. Simultaneously, air is transmitted through heat dissipation channels on the heating device, dissipating heat while transmitting air, significantly improving heat dissipation efficiency. Furthermore, the structure of the radiator, heat dissipation channels, and ventilation holes ensures smoother and faster air circulation, further facilitating heat dissipation. Moreover, the diameter of the heat dissipation channels decreases from the radiator to the heating device, reducing air pressure loss and further enhancing the radiator's heat dissipation efficiency.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1-5 As shown, a pipe sealing machine includes a housing 10 and a heating device disposed inside the housing 10. The heating device is used to melt and seal the pipe. The housing 10 is also provided with a heat dissipation device for cooling the heating device.

[0035] The heat dissipation device includes a radiator fixed on the heating device, a heat dissipation channel for heat dissipation on the heating device, and a ventilation hole 11 on the housing 10; when the heating device is cooled, the heat dissipation channel is connected to the radiator and the ventilation hole 11.

[0036] In existing technologies, when heat dissipating heat from a heating device, air is usually transmitted through pipes and then blown directly onto the heating device. Direct blowing has low heat dissipation efficiency, and the loss of air pressure during transmission leads to poor heat dissipation, meaning the temperature of the heating device drops slowly. This results in a long time interval between two sealing operations, which seriously reduces the sealing efficiency of the sealing machine.

[0037] The solution provided in this embodiment is to directly fix the radiator to the heating device, and at the same time, the radiator is connected to the heat dissipation channel provided on the heating device, and the heat dissipation channel is connected to the ventilation hole 11. That is, the air generated by the radiator directly enters the heat dissipation channel to dissipate heat from the heating device, and then the air is discharged through the ventilation hole 11. Good and directional air circulation can significantly accelerate the heat dissipation efficiency.

[0038] The heating device includes a first heating module 20, a second heating module 30 and a driving device 40 arranged opposite to each other. The driving device 40 is used to drive the first heating module 20 and the second heating module 30 to move closer to each other or further away from each other.

[0039] The heat sink is a fan 50, which includes two fans that are respectively fixed on the first heating module 20 and the second heating module 30.

[0040] Since the first heating module 20 and / or the second heating module 30 are movable, the structure of directly fixing the fan 50 to the first heating module 20 and the second heating module 30 ensures that the relative positional relationship between the fan 50 and the first heating module 20 and the second heating module 30 remains unchanged. Therefore, regardless of the position or working state of the first heating module 20 and the second heating module 30, high-efficiency and stable heat dissipation can be maintained.

[0041] The first heating module 20 includes a first fixing base 21 and a first heating element 22 that is detachably fixed on the first fixing base 21. The first fixing base 21 is provided with a first groove, and a first heat dissipation channel 61 is formed between the first groove and the first heating element 22.

[0042] The second heating module 30 includes a second fixing base 31 and a second heating element 32 that is detachably fixed on the second fixing base 31. The second fixing base 31 is provided with a second groove, and a second heat dissipation channel 62 is formed between the second groove and the second heating element 32.

[0043] In this structure, the positions of the first heat dissipation channel 61 and the second heat dissipation channel 62 enable the fan 50 to efficiently dissipate heat from the first heating element 22 and the second heating element 32, while also effectively reducing the weight of the entire sealing machine.

[0044] Two fans 50 are respectively fixed on the first fixed base 21 and the second fixed base 31, and are respectively connected to the first heat dissipation channel 61 and the second heat dissipation channel 62 through the first connecting air duct 71 and the second connecting air duct 72; the first connecting air duct 71 is not connected to the second connecting air duct 72 and the second heat dissipation channel 62; the first heat dissipation channel 61 is not connected to the second connecting air duct 72 and the second heat dissipation channel 62.

[0045] In this structure, the first connecting air duct 71 and the first heat dissipation channel 61 form a heat dissipation channel only for the first heating element 22, and the second connecting air duct 72 and the second heat dissipation channel 62 form a heat dissipation channel only for the second heating element 32. The independent heat dissipation channels can achieve more efficient heat dissipation.

[0046] The radial dimension of the first connecting air duct 71 decreases towards the first heat dissipation channel 61, and the radial dimension of the second connecting air duct 72 decreases towards the second heat dissipation channel 62.

[0047] The minimum radial dimension of the first connecting air duct 71 is greater than the maximum radial dimension of the first heat dissipation channel 61;

[0048] The minimum radial dimension of the second connecting air duct 72 is greater than the maximum radial dimension of the second heat dissipation channel 62.

[0049] The structure of the airflow gradually entering the small-diameter first heat dissipation channel 61 and second heat dissipation channel 62 from the large-diameter first connecting air duct 71 and second connecting air duct 72 can greatly reduce the loss of air pressure and improve the heat dissipation efficiency of the fan 50.

[0050] The housing 10 is also provided with a support platform 41, and the drive device 40 is set on the support platform 41. The support platform 41 has a hollow structure. The housing 10 is also provided with a number of reinforcing ribs 12, which have a hollow structure.

[0051] The hollowed-out support platform 41 can significantly reduce the weight of the entire sealing machine on the one hand, and the multiple hollowed-out structures can make the gas circulation inside and outside the sealing machine smoother, which is more conducive to the cooling of the heating device.

[0052] The hollowed-out reinforcing ribs 12 can significantly increase the stability of each component when the sealing machine is working, without causing a significant increase in its own weight.

[0053] The housing 10 is provided with a clearance section 13 for the passage of pipes, and the heating device seals the pipes in the clearance section 13.

[0054] It also includes a temperature sensor, which is used to detect the temperature of the heating device in real time.

[0055] During the operation of the pipe sealing machine, information such as whether the pipe has melted, whether it has been formed, and whether the heating device has cooled down to the point where it can be reused can all be obtained from the temperature of the heating device. Therefore, it is necessary to install a temperature sensor on the heating device.
