Description

Technical Field

[0001] This application relates to the field of air-cooled equipment, and particularly to a multi-head air-cooler. Background Art

[0002] An air-cooler is a device that uses air-cooling technology. It consists of a fan and an air duct. The fan supplies air, and the cold air is scattered on the material through the air duct to achieve the cooling of the material.

[0003] Then, the need for long-distance and multi-point cooling operations of materials in specific scenarios is becoming increasingly prominent. Most of the air-coolers on the market are designed in a single-point air outlet mode, mainly relying on a single fan and a fixed blowing pipeline to achieve the basic cooling purpose, with poor applicability, so it needs to be improved. Summary of the Invention

[0004] In order to improve the problem that the existing air-cooler can only perform air-cooling on a single point and is not applicable to multi-point cooling, this application provides a multi-head air-cooler.

[0005] The multi-head air-cooler provided by this application adopts the following technical solutions: A multi-head air-cooler includes a working frame, a fan, and an air duct. The fan is arranged on the working frame, the fan is communicated with the air duct, and a number of branch pipes are communicated with the air duct. The branch pipes are arranged along the length direction of the working frame. An air outlet head is provided at one end of the branch pipe away from the air duct, and a number of air outlets are opened on the air outlet head. The air outlets are arranged along the width direction of the working frame, and the air outlets face the working frame.

[0006] By adopting the above technical solutions, during use, the material to be cooled is placed on the working frame, the fan is started, so that the cold air enters a number of branch pipes along the air duct, then reaches the air outlet head through the branch pipes, and finally sprays out from the air outlets. The air outlet heads blow air, so that there are multiple points blowing cold air in the length direction of the entire working frame, so that the material undergoes multi-point air-cooling, realizing multi-point cooling at long distances, and having good applicability.

[0007] Optionally, a connecting pipe is fixed to the air outlet head. The connecting pipe is communicated with the air outlet head. The connecting pipe is sleeved on the branch pipe, and a fastener is provided on the connecting pipe for fixedly connecting the connecting pipe and the branch pipe.

[0008] By adopting the above technical solutions, during installation, the connecting pipe is aligned with the branch pipe and sleeved on the branch pipe, and then the connecting pipe and the branch pipe are fixed by using the fastener, realizing the installation of the air outlet head on the branch pipe.

[0009] Optionally, the fastener includes two semi-rings which are symmetrically arranged with respect to the central axis of the connecting pipe. One end of the two semi-rings close to each other is hinged to the connecting pipe, and the other ends of the two semi-rings are fixed by bolts.

[0010] By adopting the above technical solution, after the connecting pipe is sleeved on the branch pipe, the two semi-rings are driven to approach each other, so that the two semi-rings squeeze the connecting pipe, thereby pressing the connecting pipe against the branch pipe. Subsequently, the bolts are tightened to keep the two semi-rings in a state of mutual extrusion, thus realizing the clamping and fixing of the connecting pipe.

[0011] Optionally, a rotating mechanism for driving the connecting pipe to rotate is provided on the working frame. The rotating mechanism includes a driving component and a connecting component. The driving component is arranged on the working frame. The driving component is connected to the connecting component and is used to drive the connecting component to rotate. The connecting component is connected to the connecting pipe. When the connecting component rotates, it is used to drive the connecting pipe to rotate self.

[0012] By adopting the above technical solution, after the connecting pipe is sleeved on the branch pipe, the connecting component is connected to the connecting pipe, and then the driving component is started to drive the connecting component to rotate, thereby driving the connecting pipe to rotate self, so that the angle of the air outlet head changes, that is, the air outlet head inclines towards the working frame, so as to accurately cool different positions of the material.

[0013] Optionally, the driving component includes a worm and a plurality of worm wheels. The worm is arranged on the working frame, and the end of the worm is rotatably connected to the working frame. The plurality of worm wheels correspond to the branch pipes one by one. The worm wheels are rotatably connected to the working frame. The connecting pipe coaxially penetrates through the worm wheels. The worm meshes with the worm wheels. The connecting component is connected to the worm wheels.

[0014] By adopting the above technical solution, the worm is started to rotate, driving the plurality of worm wheels to rotate synchronously, so that the connecting component drives the plurality of air outlet heads to rotate by the same angle at the same time, so as to perform air cooling on the material in the entire length direction at the same angle.

[0015] Optionally, the connecting component includes a connecting crown gear and a fixed crown gear. The connecting crown gear is coaxially arranged on the worm wheel. The rotation of the worm wheel is used to drive the connecting gear to rotate synchronously. The connecting pipe coaxially penetrates through the connecting crown gear. The fixed crown gear is coaxially sleeved on the connecting pipe and is fixed to the connecting pipe. The connecting crown gear can mesh with the fixed crown gear.

[0016] By adopting the above technical solution, the connecting crown tooth meshes with the fixed crown tooth, and the side wall of the tooth on the connecting crown tooth abuts against the side wall of the tooth on the fixed crown tooth. When the worm gear rotates, it drives the connecting crown tooth to rotate synchronously, so that the tooth on the connecting crown tooth pushes against the tooth on the fixed crown tooth to move, realizing the simultaneous rotation of the fixed crown tooth, and then driving the air outlet head to rotate, realizing the adjustment of the angle of the air outlet head.

[0017] Optionally, an adjusting component for driving the connecting crown tooth to approach or move away from the fixed crown tooth is provided on the worm gear. The adjusting component includes a mounting sleeve and a moving sleeve. The mounting sleeve is coaxially fixed on the end wall of the worm gear. A plurality of sliding grooves are formed through the side wall of the mounting sleeve, and the sliding grooves are arranged along the axial direction of the mounting sleeve. The moving sleeve is coaxially sleeved on the mounting sleeve. One end of the moving sleeve away from the worm gear is coaxially fixed to the connecting crown tooth. A plurality of sliding blocks are fixed on the inner wall of the moving sleeve, and the sliding blocks are inserted into the sliding grooves and can move in the sliding grooves.

[0018] By adopting the above technical solution, the moving sleeve is driven to move, so that the sliding block moves in the sliding groove, so that the moving sleeve drives the connecting crown tooth to approach or move away from the fixed crown tooth. When the worm gear rotates, the mounting sleeve rotates synchronously, so that the inner wall of the sliding groove plays a role in pushing against the sliding block, thereby driving the moving sleeve to also drive the connecting crown tooth to rotate simultaneously.

[0019] When a part of the moving sleeve drives the connecting crown tooth to be separated from the fixed crown tooth, when the worm gear rotates, although the connecting crown tooth is still rotating, it can no longer drive the fixed crown tooth to rotate, so that the connecting pipe is in a static state at this time, that is, the air outlet head maintains the original angle unchanged, and then the angle of part of the air outlet head can be adjusted, so as to realize multi-directional comprehensive air cooling of the whole material at one time and improve the cooling efficiency.

[0020] Optionally, a moving component for driving a plurality of moving sleeves to move is provided on the working frame. The moving component includes a moving plate and a plurality of moving rods. The moving plate is slidably connected to the working frame. The moving plate is arranged along the length direction of the working frame. The moving plate can move along the width direction of the working frame. The moving rods penetrate through the moving plate. The moving rods are arranged along the width direction of the working frame. A plurality of the moving rods correspond to the branch pipes one by one. One end of the moving rod is provided with a connecting rod. A ring groove is provided on the outer side wall of the moving sleeve. One end of the connecting rod is inserted into the ring groove and can move in the ring groove.

[0021] By adopting the above technical solution, the moving plate is driven to move, driving a plurality of moving rods to move the same distance simultaneously, so that a plurality of connecting rods move synchronously. The side wall of the connecting rod abuts against the inner wall of the annular groove, thereby driving the moving sleeve to move along with the movement of the moving rod, realizing that a plurality of connecting crown teeth approach or move away from the fixed crown teeth simultaneously, and further realizing the simultaneous adjustment or stillness of the angles of a plurality of air outlets. When the moving sleeve rotates, the end of the connecting rod moves along the annular groove in the annular groove, so that the connecting rod does not interfere with the rotation of the moving sleeve.

[0022] Optionally, a limiting block is hinged to one end of the moving plate, and a positioning hole is provided on the working frame. When the limiting block is inserted into the positioning hole, the connecting crown tooth meshes with the fixed crown tooth.

[0023] By adopting the above technical solution, when the moving plate drives the moving rod to move in the direction close to the air outlet until the connecting crown tooth meshes with the fixed crown tooth, the limiting block just moves to the positioning hole. At this time, the limiting block is flipped so that the limiting block is inserted into the positioning hole, and the inner wall of the positioning hole abuts against the limiting block, thereby restricting the movement of the limiting block and positioning the moving plate on the working frame, improving the stability of the connecting crown tooth maintaining the meshing with the fixed crown tooth.

[0024] Optionally, the moving rod is threadedly connected to the moving plate, and the end of the moving rod is rotatably connected to the connecting rod.

[0025] By adopting the above technical solution, the moving rod is rotated, so that the end of the moving rod rotates on the connecting rod. Since the moving rod is threadedly connected to the moving plate, the moving rod will move along its own length direction while rotating, so that the connecting rod drives the corresponding connecting crown tooth to move, and the separation of a single connecting crown tooth from the fixed crown tooth can be realized, so that the angles of a plurality of air outlets can be independently adjusted.

[0026] In summary, the present application includes at least one of the following beneficial effects: 1. Start the rotation of the worm, driving a plurality of worm wheels to rotate synchronously, so that the connecting component drives a plurality of air outlets to rotate the same angle simultaneously, so as to perform air cooling at the same angle on the materials in the entire length direction; 2. Rotate the moving rod, so that the end of the moving rod rotates on the connecting rod. Since the moving rod is threadedly connected to the moving plate, the moving rod will move along its own length direction while rotating, so that the connecting rod drives the corresponding connecting crown tooth to move, and the separation of a single connecting crown tooth from the fixed crown tooth can be realized, so that the angles of a plurality of air outlets can be independently adjusted.

Detailed implementation manners

[0029] The following further Figures 1 - 3 describes the present application in detail.

[0030] The embodiment of the present application discloses a multi-head air-cooling machine. Referring to Figure 1 Figure 2 , a multi-head air-cooling machine includes a working rack 10, a fan 20 and an air duct 30. Among them, the fan 20 is arranged on the working rack 10 and communicated with the air duct 30. A plurality of branch pipes 31 are communicated with the air duct 30, and the plurality of branch pipes 31 are arranged along the length direction of the working rack 10. An air outlet head 40 is provided at one end of each branch pipe 31 away from the air duct 30. A plurality of air outlets are formed on the air outlet head 40, and the plurality of air outlets are arranged along the width direction of the working rack 10, and the air outlets face the working rack 10. This structure realizes multi-dimensional air-cooling coverage.

[0031] Among them, the air outlet head 40 can adopt the form of a telescopic sleeve, so that the length of the air outlet head 40 can be adjusted to adapt to working racks 10 of different widths and meet the air-cooling requirements for materials laid with different widths.

[0032] Referring to Figure 1 Figure 3 , specifically, a connecting pipe 41 is fixed on the air outlet head 40, and the connecting pipe 41 is communicated with the air outlet head 40. The connecting pipe 41 is sleeved on the branch pipe 31 and fixedly connected through a fastener 50. For example, the fastener 50 can be composed of two semi-rings 51. The two semi-rings 51 are symmetrically distributed with respect to the central axis of the connecting pipe 41, and the two ends are respectively connected to the connecting pipe 41 through hinges and can be fixedly clamped through bolts 52 in the middle part. In addition, a snap-fastening joint or a threaded locking fastener can also be selected to replace the above structure to meet the requirements of different application scenarios.

[0033] To further increase the functionality of the device, a throttle valve can be installed inside the branch pipe 31 to control the air flow rate. For example, manual adjustment components such as butterfly valves or needle valves can be selected, or an electric proportional regulating valve can be used to achieve precise automated control.

[0034] Refer to Figure 1 Figure 2 , in order to change the air outlet angle of the air outlet head 40 and cool the material more precisely, a rotating mechanism 60 is provided on the working frame 10. The rotating mechanism 60 is used to drive the connecting pipe 41 to rotate around its own axis, thereby changing the blowing angle. The rotating mechanism 60 includes two parts: a driving component 61 and a connecting component 62.

[0035] Refer to Figure 1 Figure 3 , the driving component 61 includes a worm 611 and a number of worm wheels 612. The worm 611 is installed on the working frame 10 and can rotate forward and backward. A motor is installed on the working frame 10 through bolts 52, and the output end of the motor is coaxially fixed to one end of the worm 611 for driving the worm 611 to rotate. Each worm wheel 612 corresponds to a branch pipe 31, and the worm 611 meshes with the worm wheels 612. The connecting component 62 includes a connecting crown gear 621 and a fixed crown gear 622. The connecting crown gear 621 is coaxially arranged on the worm wheel 612, and when the worm wheel 612 rotates, it drives the connecting crown gear 621 to rotate synchronously; the connecting pipe 41 coaxially passes through the connecting crown gear 621, and the fixed crown gear 622 is coaxially sleeved on the connecting pipe 41 and fixedly connected to the connecting pipe 41. The connecting crown gear 621 can mesh with the fixed crown gear 622. In this way, when the worm wheel 612 rotates, through the cooperation of the connecting crown gear 621 and the fixed crown gear 622, the self-rotation of the connecting pipe 41 can be realized.

[0036] The rotation angle of the motor can be controlled by programming, so that the rotation angle of the worm wheel 612 can be controlled, and further the precise control of the rotation angle of the air outlet head 40 can be achieved.

[0037] Refer to Figure 2 Figure 3 , in order to uniformly control the angle adjustment of multiple connecting pipes 41, a moving component 80 is provided on the working frame 10. The moving component 80 includes a moving plate 81 and a number of moving rods 82. The moving plate 81 is slidably connected to the working frame 10 and moves along the width direction of the working frame 10. The moving rods 82 pass through the moving plate 81 and are connected to the corresponding moving sleeves 72. The moving sleeves 72 are located between the connecting crown gear 621 and the fixed crown gear 622. Controlled by the movement of the moving plate 81, the connecting crown gear 621 is urged to approach or move away from the fixed crown gear 622, thereby realizing the meshing or separation of the connecting crown gear 621 and the fixed crown gear 622.

[0038] Refer to Figure 1 Figure 3, wherein the movement of the connecting crown gear 621 is implemented by an adjusting assembly 70. The adjusting assembly 70 includes a mounting sleeve 71 and a moving sleeve 72. The mounting sleeve 71 is coaxially fixed on the end wall of the worm gear 612. A plurality of sliding grooves 711 are formed through the side wall of the mounting sleeve 71. The sliding grooves 711 are arranged along the axial direction of the mounting sleeve 71. The moving sleeve 72 is coaxially sleeved on the mounting sleeve 71. One end of the moving sleeve 72 away from the worm gear 612 is coaxially fixed to the connecting crown gear 621. A plurality of sliding blocks 721 are fixed on the inner wall of the moving sleeve 72. The sliding blocks 721 are inserted into the sliding grooves 711 and can move in the sliding grooves 711. The moving rod 82 is threadedly connected to the moving plate 81. One end of the moving rod 82 is rotatably connected to a connecting rod 83. A ring groove 722 is provided on the outer side wall of the moving sleeve 72. One end of the connecting rod 83 is inserted into the ring groove 722 and can move in the ring groove 722.

[0039] When the moving plate 81 moves, it will drive all the moving rods 82 to move simultaneously, so that the connecting rod 83 pushes against the inner wall of the ring groove 722 to move, driving the moving sleeve 72 to move, so that the sliding block 721 moves in the sliding groove 711, thereby making the moving sleeve 72 drive the connecting crown gear 621 to approach or move away from the fixed crown gear 622. When the worm gear 612 rotates, the mounting sleeve 71 rotates synchronously, so that the inner wall of the sliding groove 711 plays a role in pushing against the sliding block 721, thereby driving the moving sleeve 72 to also drive the connecting crown gear 621 to rotate simultaneously. If the connecting crown gear 621 meshes with the fixed crown gear 622, that is, the connecting pipe 41 rotates with the rotation of the worm gear 612. If the connecting crown gear 621 is separated from the fixed crown gear 622, the connecting pipe 41 will not rotate with the worm gear 612, realizing whether the air outlet head 40 is angle-adjusted or not, and is not restricted by the rotation of the worm 611.

[0040] Refer to Figure 1 Figure 3 , wherein, since the moving rod 82 is threadedly connected to the moving plate 81, rotating the moving rod 82 causes the moving rod 82 to move along its own length direction while rotating, so that the connecting rod 83 drives the corresponding connecting crown gear 621 to move, and the separation of a single connecting crown gear 621 from the fixed crown gear 622 can be realized.

[0041] When some of the moving sleeves 72 drive the connecting crown gears 621 to be separated from the fixed crown gears 622, the worm gear 612 rotates. Although the connecting crown gears 621 are still rotating, they can no longer drive the fixed crown gears 622 to rotate, so that the connecting pipe 41 is in a stationary state at this time, that is, the air outlet head 40 maintains the original angle unchanged. Furthermore, the angle adjustment of some of the air outlet heads 40 can be realized, so as to realize multi-directional comprehensive air cooling of the whole material at one time and improve the cooling efficiency. When the moving sleeve 72 rotates, the end of the connecting rod 83 moves along the ring groove 722 relative to the ring groove 722, so that the connecting rod 83 does not interfere with the rotation of the moving sleeve 72.

[0042] Referring to Figure 1 Figure 3 , in order to improve the stability of the connecting crown gear 621 to maintain the meshing or non-meshing state with the fixed crown gear 622, a limiting block 811 is hinged at one end of the moving plate 81. There is a positioning hole 11 on the working frame 10. When the limiting block 811 is inserted into the positioning hole 11, the connecting crown gear 621 and the fixed crown gear 622 are in the meshing state. At this time, starting the driving assembly 61 can realize the rotation action of the connecting pipe 41. On the contrary, if the limiting block 811 disengages from the positioning hole 11, the connecting crown gear 621 can be separated from the fixed crown gear 622, and the connecting pipe 41 stops rotating.

[0043] At the same time, a limiting hole 12 is also opened on the working frame 10. The limiting hole 12 is located on the side of the positioning hole 11 away from the air outlet head 40. The limiting block 811 can also be turned and inserted into the limiting hole 12. At this time, the connecting crown gear 621 and the fixed crown gear 622 can be in a separated state, ensuring that when the angle adjustment of the air outlet head 40 is not required, the situation that the air outlet head 40 and the worm gear 612 rotate together will not occur.

[0044] The implementation principle of an air-cooling machine with multiple heads in an embodiment of the present application is as follows: During use, the material to be cooled is placed on the working frame 10, and the fan 20 is started, so that the cold air enters several branch pipes 31 along the air duct 30, then reaches the air outlet head 40 through the branch pipes 31, and finally sprays out from the air outlet. The multiple air outlet heads 40 blow air, so that there are multiple points blowing cold air in the length direction of the entire working frame 10, thereby enabling the material to be cooled by multiple points of air cooling, realizing multi-point cooling at multiple positions over a long distance, and having good applicability.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
