Description

Air-cooled equipment for geocells Technical Field

[0001] This invention relates to the field of ultrasonic welding equipment technology, and more specifically to air-cooled equipment for geocells. Background Technology

[0002] Geocells are a three-dimensional mesh structure formed by high-strength welding of reinforced HDPE sheets. They are generally manufactured using an ultrasonic welding production line. The welding head transmits the received vibration energy to the joint of the workpieces to be welded. In this area, the vibration energy is converted into heat energy through friction, melting the surface of the workpieces to be welded, thus allowing the two workpieces to be welded together.

[0003] In the prior art, the working equipment generates a lot of heat when welding geocells with ultrasonic waves, thus requiring cooling equipment to reduce the temperature. For example, an automatic cooling system for an ultrasonic welding production line of geocells, disclosed in CN110789130A, includes a mounting frame. An mounting plate is fixedly mounted on the upper surface of the mounting frame, and electric push rods are uniformly fixedly mounted on the lower surface of the mounting plate. An ultrasonic transducer is fixedly mounted on the lower surface of the electric push rod, and an ultrasonic welding head is fixedly mounted on the lower surface of the ultrasonic transducer through a transmission mechanism.

[0004] This automatic cooling system uses two liquid inlet and outlet pipes to cool several miniature heat exchangers below. However, as the liquid flows through the inlet pipe, the flow rate of coolant supplied to the miniature heat exchangers decreases, resulting in varying degrees of cooling in the lower cooling structure and making it difficult to cool the distant working equipment. Furthermore, this cooling structure cools the interior of the working equipment through conduits, but cannot cool the outer surface of the working equipment or the geocells below after welding. Summary of the Invention

[0005] The purpose of this invention is to solve the problems of uneven working flow inside the inlet pipe in the above-mentioned background technology, which leads to different cooling levels of the working equipment below and the inability to cool the outer surface of the working equipment and the geocells welded below, and to propose an air-cooling device for geocells.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] An air-cooled device for geocells includes a base plate, a mounting plate on top of the base plate, and an air intake structure on top of the mounting plate. The air intake structure includes:

[0008] An air intake plate is installed on top of the mounting plate. An air intake groove is provided inside the air intake plate. Connecting pipes are provided on both sides of the air intake groove and connected to the blowing equipment. Several miniature heat exchangers are provided at the bottom of the air intake plate, and several ventilation grooves are provided on both sides of the bottom of the air intake plate.

[0009] A sliding plate is slidably connected to the bottom of the air intake plate. The surface of the sliding plate is provided with several ventilation slots and cooling slots. One end of the sliding plate is provided with a return spring connected to the air intake plate, and the other end of the sliding plate is provided with a metal connecting plate. An electromagnet is provided on the side of the air intake plate near the metal connecting plate.

[0010] The number, location, and shape of several micro heat exchangers are adapted to the cooling air troughs; the number, location, and shape of several venting bottom troughs are adapted to the venting troughs.

[0011] A cooling structure is provided below the mounting plate, the cooling structure including:

[0012] Several boxes are set below the micro heat exchanger. Each box is equipped with an electric push rod inside, and the output end of the electric push rod is equipped with an ultrasonic welding head.

[0013] The corresponding miniature heat exchanger, housing, and ultrasonic welding head are connected by several flexible hoses. An air outlet box is installed above the air inlet plate, and the air outlet box is connected to the ultrasonic welding head by a flexible hose.

[0014] As a further aspect of the present invention: two limiting rods are provided on the inner walls of both sides of the air intake channel. The limiting rods are located above the sliding plate and in contact with the sliding plate, and the limiting rods limit the connection of the sliding plate.

[0015] As a further aspect of the present invention: a first connecting hose is provided between the micro heat exchanger and the housing, and an electromagnetic valve is provided between the first connecting hose and the micro heat exchanger.

[0016] As a further aspect of the present invention: a second connecting hose connects the housing and the ultrasonic welding head, and a third connecting hose connects the ultrasonic welding head and the exhaust box.

[0017] As a further aspect of the present invention: an air pump is provided between the third connecting hose and the air outlet box.

[0018] As a further aspect of the present invention: a fan is provided inside the housing, and the fan is located on the opposite side of the first connecting hose.

[0019] As a further embodiment of the present invention: several ventilation grooves 44 on both sides of the bottom of the air intake plate are inclined.

[0020] As a further aspect of the present invention, the distance between adjacent ventilation troughs is greater than the diameter of the ventilation trough itself.

[0021] The beneficial effects of this invention are:

[0022] (1) The air-cooling device for geocells of the present invention is provided with an air intake structure. Air blowing devices are provided on both sides of the air intake channel inside the air intake plate through connecting pipes. The air blowing devices on both sides form convection in the air intake channel, so that the cooling air can flow evenly to the cooling structure below for cooling, avoiding the situation where the air flow is uneven due to the air only flowing in one direction.

[0023] (2) The air-cooling device for geocells of the present invention is provided with a sliding plate. The sliding plate slides under the force of an electromagnet, thereby blocking the input end of the micro heat exchanger and connecting the ventilation bottom groove with the air inlet groove. This allows the convective air in the air inlet groove to overflow directly from the ventilation bottom groove, thereby cooling and dissipating heat on the outer surface of the micro heat exchanger, the box, the ultrasonic welding head, and the geocell after welding on the bottom plate.

[0024] (3) The air-cooled equipment for geocells of the present invention is provided with a cooling structure. The micro heat exchanger, the box and the ultrasonic welding head of the cooling structure are connected by several hoses, so that the electric push rod avoids the pipes affecting the movement when it drives the ultrasonic welding head to weld.

[0025] (4) The air-cooled equipment for geocells of the present invention is provided with an air outlet box. The air cooled by the equipment will flow into the air outlet box separately, which facilitates the reprocessing and recycling of the cooled air after heat absorption. The separate collection avoids pollution of the newly produced cooled air. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please refer to Figures 1-6. The present invention is an air-cooled device for geocells, including a base plate 1, support plates 2 on both sides of the base plate 1, an mounting plate 3 on the top of the support plates 2, an air intake structure 4 on the top of the mounting plate 3, an air intake plate 41 of the air intake structure 4 on the top of the mounting plate 3, an air intake groove 42 inside the air intake plate 41, the air intake groove 42 extending through both sides of the air intake plate 41, an installation groove at the bottom of the air intake groove 42, a sliding plate 45 slidably disposed in the installation groove, a return spring 47 between one end of the sliding plate 45 and the inner wall of the air intake plate 41, a metal connecting plate 48 on the other side of the sliding plate 45 where the return spring 47 is disposed, and an electromagnet 49 on the side of the installation groove near the metal connecting plate 48. Two limiting rods 43 are fixedly installed on the inner walls of both sides of the air inlet channel 42. The limiting rods 43 are located on both sides above the sliding plate 45 and contact the top surface of the sliding plate 45, thus limiting the sliding plate 45. Several ventilation slots 44 are provided on both sides of the air inlet plate 41, arranged in two rows with equal distances between slots in the same row. Several miniature heat exchangers 51 are provided at the bottom of the air inlet plate 41, arranged in a row with equal distances. Several ventilation slots 46 are opened on both sides of the sliding plate 45, the number, shape, and position of which correspond to the ventilation slots 44. Several cooling slots 410 are opened on both sides of the sliding plate 45, located between the ventilation slots 44 on both sides, the number, shape, and position of which correspond to the miniature heat exchangers 51. The air intake plate 41 is detachably provided with sealing plates 411 on both sides. Each sealing plate 411 is provided with a connecting pipe 412. When the sealing plate 411 seals the air intake channel 42, the connecting pipes 412 on both sides are connected to the air intake channel 42.

[0036] A cooling structure 5 is provided at the bottom of the mounting plate 3. Several mounting trays 53 of the cooling structure 5 are arranged at the bottom of the mounting plate 3. The number and position of the mounting trays 53 are adapted to the micro heat exchanger 51. The mounting trays 53 are located below the micro heat exchanger 51. Each mounting tray 53 has a housing 54 at its bottom. An ultrasonic welding device is installed inside the housing 54. A first connecting hose 52 is provided between each housing 54 and the micro heat exchanger 51 above it. A solenoid valve 512 is provided at the end of the first connecting hose 52 closest to the micro heat exchanger 51. A fan 510 is provided inside the housing 54. An electric push rod 55 is provided inside each housing 54. An ultrasonic welding head 57 is provided at the bottom of the output end of the electric push rod 55. A second connecting hose 56 is provided between the ultrasonic welding head 57 and the housing 54. An air outlet box 59 is provided on the top of the air inlet plate 41. The air outlet box 59 has an inner cavity. The ultrasonic welding head 57 is provided with a second connecting hose 56 and a third connecting hose 58 is provided on the other side. The other end of the third connecting hose 58 extends upward and communicates with the inner cavity of the air outlet box 59. A vacuum pump 511 is provided between each third connecting hose 58 and the air outlet box 59.

[0037] When using this air-cooled geocell equipment, the geocell to be welded is placed on the base plate 1, directly below several ultrasonic welding heads 57. Then, the air blowers on both sides of the connecting pipe 412 are activated, blowing cooled air through the connecting pipe 412 into the air inlet channel 42, creating convection inside the air inlet channel 42. The cooled air overflows from several cooling air slots 410 at the bottom of the sliding plate 45 and flows into the micro heat exchanger 51. Then, the solenoid valve 512 is activated, allowing the cooled air to flow from the inside of the micro heat exchanger 51 through the first connecting hose 52 into the housing 54. The cooled air cools the equipment inside the housing 54. The fan 510 is then activated, accelerating the flow of cooled air to improve cooling efficiency. At the same time, the accelerated airflow inside the housing 54 generates negative pressure, increasing the airflow speed. Then, the electric actuators 55 are activated, and several electric actuators 55 drive the ultrasonic welding head 57 downward to weld the geocells on the surface of the base plate 1. Cooling air enters the interior of the ultrasonic welding head 57 through the second connecting hose 56, and then flows out through the third connecting hose 58 to dissipate heat from the ultrasonic welding head 57. The air that has absorbed a large amount of heat flows out from the third connecting hose 58 into the upper air outlet box 59. The air flowing inside the air outlet box 59 is recycled by the equipment, so that it can be further fed into the air blowing equipment and re-enter the connecting pipe 412 to complete the cooling cycle. After welding is completed, the electromagnet 49 is activated. The electromagnet 49 begins to attract the nearby metal connecting plate 48. The metal connecting plate 48 drives the sliding plate 45 to slide relative to each other in the mounting groove. At this time, the reset spring 47 on the other side begins to extend until the electromagnet 49 tightly attracts the metal connecting plate 48. The cooling air groove 410 at the bottom of the sliding plate 45 is staggered with the input end of the micro heat exchanger 51, so that the input end of the micro heat exchanger 51 is blocked by the bottom surface of the sliding plate 45. At the same time, the several ventilation grooves 46 on the surface of the sliding plate 45 are connected to the several ventilation bottom grooves 44 at the bottom of the air inlet plate 41, so that the airflow of the air blowing equipment on both sides enters the air inlet groove 42 from the connecting pipe 412, and then overflows to the outside from the several ventilation grooves 46 and ventilation bottom grooves 44 below. The overflowing air can cool and dissipate heat on the outer surface of the micro heat exchanger 51, the box 54, the ultrasonic welding head 57, and the geocell welded on the surface of the bottom plate 1. After cooling is complete, the switch of electromagnet 49 is turned off, and sliding plate 45 is restored by the traction force of return spring 47, so that the bottom of venting groove 44 is blocked by the bottom of sliding plate 45. At the same time, the output end of miniature heat exchanger 51 set in the middle of the bottom of air inlet plate 41 is connected to cooling air groove 410.

[0038] The fan 510 is positioned on the opposite side of the first connecting hose 52, allowing the air blown in by the first connecting hose 52 to form convection with the fan 510, thereby providing all-round heat dissipation and cooling for the interior of the housing 54. The lengths of the second connecting hose 56 and the third connecting hose 58 are designed to allow for deformation, so that when the electric push rod 55 moves the ultrasonic welding head 57, the second connecting hose 56 and the third connecting hose 58 will not be pulled by traction. Several ventilation grooves 44 on both sides of the bottom of the air inlet plate 41 are inclined, allowing cooling air to pass through the inclined ventilation grooves 44 to cool the welded geocell in the center of the bottom plate 1. The distance between adjacent ventilation grooves 44 is greater than the diameter of the ventilation groove 44 itself, so that the bottom of the corresponding sliding plate 45 can block the ventilation groove 44 during the sliding process.

[0039] The working principle of this invention: The air-cooled device for geocells of this invention features an air intake structure 4. Air blowing devices are installed on both sides of the air intake channel 42 inside the air intake plate 41 via connecting pipes 412. These air blowing devices create convection within the air intake channel 42, allowing cooling air to flow evenly to the cooling structure 5 below for cooling, avoiding uneven airflow caused by air flowing only to one side. Furthermore, the cooling structure 5 is connected to the micro heat exchanger 51, the housing 54, and the ultrasonic welding head 57 via several flexible hoses, preventing the pipes from interfering with the movement of the electric push rod 55 when it drives the ultrasonic welding head 57 for welding. The system features an exhaust box 59, which allows the cooled air to flow separately into the exhaust box 59. This facilitates the reprocessing and recycling of the cooled air after heat absorption, and separate collection prevents pollution of newly produced cooled air. A sliding plate 45 is also included, which slides under the force of an electromagnet 49. This blocks the input end of the micro heat exchanger 51 while connecting the ventilation trough 44 with the inlet trough 42. This allows the convective air in the inlet trough 42 to overflow directly from the ventilation trough 44, thereby cooling the outer surfaces of the micro heat exchanger 51, the housing 54, the ultrasonic welding head 57, and the geocell welded to the base plate 1.

[0040] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
