Description

Technical Field

[0001] The present invention relates to the technical field of silicone tubes, and in particular to a cooling device for assembling silicone tubes. Background Art

[0002] Silicone tubing is a special type of rubber with excellent comprehensive properties. It has excellent electrical insulation, aging resistance, chemical stability, oxidation resistance, weather resistance, radiation resistance, physiological inertness, good air permeability, and high and low temperature resistance. It can be used for long-term use in temperatures of -60°C to 250°C. It is widely used in aviation, electronics, petroleum, chemical, machinery, electrical appliances, medical, ovens, food, and other industrial sectors as an excellent electrical insulation seal and liquid conveying material. Silicone rubber also has excellent high and low temperature resistance, oil resistance, and is non-toxic and odorless. The operating temperature range of silicone rubber is from -100°C to 350°C, and it has excellent resistance to thermal oxygen aging, ozone aging, light aging, and weather aging. Currently, glass fiber silicone tubing is produced by thermally compounding glass fiber silicone into a tubular shape using a thermal compounding device, and then assembling joints and other accessories for different applications.

[0003] During the assembly process, a clamp is usually used to clamp the silicone tube and the connector, and then the two are connected for assembly. However, the following problems may occur during the actual operation:

[0004] 1. During the assembly process, the temperature of the silicone tubes just off the production line is high, so they need to be cooled by a cooling device. Most existing devices accelerate the air flow near the silicone tubes to achieve rapid cooling of the silicone tubes. However, since the temperature near the production line is usually higher and the temperature difference with the silicone tubes is small, the cooling speed of the silicone tubes is relatively slow.

[0005] 2. In existing devices, it is usually necessary to send the end of the silicone tube into the cooling mechanism for cooling through a clamping component. The high-temperature silicone tube is prone to deformation during the clamping process. Summary of the Invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide a cooling device for silicone tube assembly, which can reduce the cooling time of the silicone tube and accelerate the cooling efficiency of the silicone tube.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] A cooling device for assembling silicone tubes comprises a workbench, a cooling mechanism fixedly mounted on the middle of the upper surface of the workbench, a pair of conveying mechanisms symmetrically arranged on both sides of the cooling mechanism and fixedly connected to the workbench, a pair of guide members symmetrically arranged front-to-back between the two conveying mechanisms and with the middle part thereof laterally passing through the cooling mechanism, and a pair of clamping mechanisms symmetrically arranged front-to-back on the right side of the workbench; the cooling mechanism comprises a cooling cylinder fixedly mounted laterally on the middle of the upper surface of the workbench and having a first cavity therein, a cooling component rotatably arranged on one side of the interior of the cooling cylinder, a cooling liquid circulation component arranged on one side of the upper surface of the workbench and connected to the cooling cylinder, a suction machine arranged on the input side of the cooling cylinder, and a cooling liquid circulation component arranged on the input side of the cooling cylinder. The upper surface of the workbench is located on one side of the cooling component and is used to drive the cooling component to rotate; the cooling component includes a pair of rotating liquid storage rings symmetrically arranged on both sides of the cooling cylinder and a spiral cooling tube with a middle part laterally arranged on one side of the cooling cylinder and two ends respectively connected with the rotating liquid storage rings on the corresponding sides; a second cavity is provided in the rotating liquid storage ring, the inner side of the second cavity is connected with the first cavity and the lower part is connected with the spiral cooling tube through a connecting tube; the inner diameter of the spiral cooling tube is larger than the radius of the cooling cylinder; each connecting tube is detachably connected to its corresponding rotating liquid storage ring; the middle parts of the two guide members are laterally penetrated in the spiral cooling tube and respectively abut against the lower parts of both sides of the silicone tube.

[0009] More preferably, the coolant circulation assembly includes a circulation pipe whose liquid inlet end is connected to one side of the cooling cylinder input end and whose liquid outlet end is connected to the other side of the cooling cylinder output end, and a water pump connected to the circulation pipe.

[0010] More preferably, the driving assembly includes a rotating gear fixedly mounted on the outside of one of the rotating liquid storage rings, a first mounting plate fixedly mounted on the upper surface of the workbench and located on one side of the rotating gear, a driving gear rotatably arranged on one side of the first mounting plate and meshing with the rotating gear, and a first driving motor fixedly mounted on the other side of the first mounting plate and with the driving end fixedly connected to the driving gear after passing through the first mounting plate.

[0011] More preferably, the conveying mechanism includes a first linear drive vertically fixed on the upper surface of the workbench input end, a mounting seat fixed to the mounting seat of the telescopic end of the first linear drive, a conveying roller rotatably installed in the mounting seat and arranged perpendicular to the conveying direction of the silicone tube, and a second driving motor fixed on one of the outer walls of the mounting seat and with the driving end fixedly connected to the shaft end of the conveying roller after passing through the outer wall.

[0012] More preferably, both ends of each guide member are fixedly connected to the mounting seats in the two conveying mechanisms.

[0013] More preferably, each set of clamping mechanisms includes a second mounting plate fixed to one side of the upper surface of the workbench, a second linear drive vertically fixed to the middle of the inner side surface of the second mounting plate, and a clamping plate fixed to the telescopic end of the second linear drive; the clamping plates of the two sets of clamping mechanisms are arranged opposite to each other.

[0014] The present invention has the following beneficial effects:

[0015] 1. In the present invention, the ambient temperature is lowered by the cooling cylinder to increase the temperature difference between the end of the silicone tube entering the cooling cylinder and the ambient environment, thereby achieving initial cooling of the end of the silicone tube. Subsequently, the coolant flows in the spiral cooling tube that is against one side of the silicone tube and the suction machine drives the rapid circulation of air in the cooling cylinder to achieve secondary double cooling of the silicone tube, thereby accelerating the cooling speed of the silicone tube and improving the efficiency of the silicone tube during assembly.

On the one hand, the clamping time of the silicone tube is reduced as much as possible, thereby avoiding the deformation of the silicone tube during the clamping process as much as possible. On the other hand, it also saves the time of sending the silicone tube from the input end of the workbench into the cooling mechanism, thereby improving the cooling efficiency.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] A cooling device for assembling a silicone tube comprises a workbench 1, a cooling mechanism 3 fixedly mounted in the middle of the upper surface of the workbench 1, a pair of conveying mechanisms 2 symmetrically arranged on both sides of the cooling mechanism 3 and fixedly connected to the workbench 1, a pair of guide members 5 symmetrically arranged between the two conveying mechanisms 2 and with the middle portion thereof laterally passing through the cooling mechanism 3, and a pair of clamping mechanisms 4 symmetrically arranged on the right side of the workbench 1; the cooling mechanism 3 comprises a cooling cylinder 31 laterally fixedly mounted in the middle of the upper surface of the workbench 1 and provided with a first cavity 311 therein, a cooling component 32 rotatably mounted in the middle portion on one side of the interior of the cooling cylinder 31, a cooling liquid circulation component 33 arranged on one side of the upper surface of the workbench 1 and connected to the cooling cylinder 31, a suction machine 34 arranged on the input side of the cooling cylinder 31, and a cooling liquid circulation component 33 arranged on the upper surface of the workbench 1 at the cooling component 31. 32 side and is used to drive the cooling component 32 to rotate; the cooling component 32 includes a pair of rotating liquid storage rings 321 symmetrically arranged on both sides of the cooling cylinder 31 and a spiral cooling tube 322 whose middle part is horizontally arranged on one side of the cooling cylinder 31 and whose two ends are respectively connected with the rotating liquid storage ring 321 on the corresponding side; a second cavity 3211 is provided in the rotating liquid storage ring 321, the inner side of the second cavity 3211 is connected with the first cavity 311 and the lower part is connected with the spiral cooling tube 322 through a connecting tube 323; the inner diameter of the spiral cooling tube 322 is larger than the radius of the cooling cylinder 31; each connecting tube 323 is detachably connected to its corresponding rotating liquid storage ring 321; the middle parts of the two guide members 5 are horizontally passed through the spiral cooling tube 322 and respectively abut against the lower parts of both sides of the silicone tube.

[0031] By replacing the spiral cooling tube 322 with a corresponding size according to the diameter of the silicone tube, it is achieved that when the rotating liquid storage ring 321 drives the spiral cooling tube 322 to rotate, the tube wall on one side of the silicone tube always maintains a state of abutting the spiral cooling tube 322, thereby driving the cooling of the spiral cooling tube 322 through the flow of coolant in the spiral cooling tube 322, and then driving the cooling of the silicone tube; in this device, the ambient temperature is lowered by the cooling cylinder 31 to increase the temperature difference between the end of the silicone tube entering the cooling cylinder 31 and the ambient temperature, so as to achieve preliminary cooling of the end of the silicone tube, and then the coolant is passed through the spiral cooling tube abutting against one side of the silicone tube. The flow in 322 and the rapid circulation of air in the cooling cylinder 31 driven by the suction machine 34 can achieve secondary double cooling of the silicone tube, so as to speed up the cooling speed of the silicone tube and improve the efficiency of the silicone tube during assembly; in this device, the tube end of the silicone tube can be transported by the arrangement of two conveying mechanisms 2 and the guide member 5, and there is no need to send the tube end of the silicone tube into the cooling mechanism 3 for cooling through the clamping assembly. On the one hand, the clamping time of the silicone tube is reduced as much as possible, thereby avoiding the deformation of the silicone tube during the clamping process as much as possible. On the other hand, it also saves the time of sending the silicone tube from the input end of the workbench 1 to the cooling mechanism 3, thereby improving the cooling efficiency.

[0032] As a possible implementation scheme of this solution, preferably, the coolant circulation component 33 includes a circulation pipe 331 whose liquid inlet end is connected to one side of the input end of the cooling cylinder 31 and whose liquid outlet end is connected to the other side of the output end of the cooling cylinder 31, and a water pump 332 connected to the circulation pipe 331; through the action of the water pump 332, the coolant can flow in the spiral cooling tube 322 in the opposite direction of the conveying direction, thereby accelerating the cooling of the silicone tube.

[0033] As a possible implementation of the present scheme, preferably, the driving assembly 35 includes a rotating gear 351 fixedly mounted on the outside of one of the rotating liquid storage rings 321, a first mounting plate 352 fixedly mounted on the upper surface of the workbench 1 and located on one side of the rotating gear 351, a driving gear 353 rotatably arranged on one side of the first mounting plate 352 and meshing with the rotating gear 351, and a first driving motor 354 fixedly mounted on the other side of the first mounting plate 352 and fixedly connected to the driving gear 353 after the driving end passes through the first mounting plate 352; the driving gear 353 is driven to rotate by the first driving motor 354, thereby driving the rotating gear 351 to rotate through the meshing action, so that the rotating liquid storage ring 321 drives the spiral cooling tube 322 and the other rotating liquid storage ring 321 to rotate, thereby realizing cooling of the silicone tube.

[0034] As a possible implementation of the present scheme, preferably, the conveying mechanism 2 includes a first linear drive 24 vertically fixed on the upper surface of the input end of the workbench 1, a mounting base 21 fixed on the telescopic end of the first linear drive 24, a conveying roller 22 circumferentially rotatably installed in the mounting base 21 and arranged perpendicular to the conveying direction of the silicone tube, and a second drive motor 23 fixed on one of the outer walls of the mounting base 21 and with the driving end fixedly connected to the axial end of the conveying roller 22 after passing through the outer wall; the conveying roller 22 is driven to rotate by the second drive motor 23, so that the silicone tube can be gradually conveyed to the spiral cooling tube 322 in the cooling cylinder 31 for cooling.

[0035] As a possible implementation scheme of the present invention, preferably, both ends of each guide member 5 are fixedly connected to the mounting seats 21 in the two conveying mechanisms 2 respectively; the setting of the guide member 5 can guide the silicone tube to avoid the silicone tube falling from the gap between the conveying roller 22 and the spiral cooling tube 322 during the process of the conveying roller 22 conveying the silicone tube, thereby affecting the cooling of the spiral cooling tube 322.

[0036] As a possible implementation of the present scheme, preferably, each group of clamping mechanisms 4 includes a second mounting plate 41 fixed on one side of the upper surface of the workbench 1, a second linear drive 42 vertically fixed to the middle of the inner side surface of the second mounting plate 41, and a clamping plate 43 fixed to the telescopic end of the second linear drive 42; the clamping plates 43 of the two groups of clamping mechanisms 4 are arranged opposite to each other; the tube ends of the silicone tube can be clamped by the two clamping plates 43, and at the same time, in order to avoid deformation of the silicone tube caused by excessive force of the two clamping plates 43 during the clamping process, an elastic layer (not shown in the figure) can be covered on the inner side surface of the clamping plate 43.

[0037] The general working process of this device is as follows:

[0038] First, select a spiral cooling tube 322 of corresponding size based on the outer diameter of the silicone tube. Install the spiral conveying tube 322 onto the two rotating liquid storage rings 321 via two connecting tubes 323. Then adjust the extension distance of the linear actuator 42 so that the center line of the silicone tube, which is mounted on the conveying roller 22 at the input end of the workbench 1, is aligned with the center axis of the two rotating liquid storage rings 321.

[0039] In the second step, the first drive motor 354 drives the drive gear 353 to rotate, which in turn drives the rotating gear 351 to rotate through meshing, thereby driving the cooling assembly 32 to rotate, turning on the suction machine 34, and then turning on the second drive motor 23 located on the input side of the workbench 1, so that the end of the silicone tube mounted above the conveying roller 22 on this side is transported into the cooling mechanism 3. The silicone tube end is cooled while moving in the cooling mechanism 3;

[0040] The third step is to stop the first drive motor 354, the second drive motor 23 and the suction machine 34 when the end of the silicone tube moves between the two clamping plates 43. Then, the two second linear drives 42 are driven to drive the two clamping plates 43 to move closer to each other until the two clamping plates 43 clamp the end of the silicone tube. At this time, the end of the silicone tube can be installed.

Any equivalent structural transformation made by using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
