Description

Technical Field

[0001] The utility model relates to the field of ceramic tile manufacturing, in particular to a fan control device. Background Art

[0002] At present, ceramic tiles are in a high-temperature state after being fired out of the kiln, so they need to be further cooled through a fan cooling line. In the existing fan cooling line, for example, a Chinese patent document discloses a technical solution with a patent application number of 202022070708.8, entitled "An energy-saving fan intelligent control system for tile cooling". The solution mainly includes a conveying line composed of several sections of conveyor racks, each of which is provided with a support rack. The top of each support rack is equipped with a cooling fan with an air outlet inclined towards the tiles. Each conveyor rack is also provided with a photoelectric eye for sensing the incoming bricks, and one of the conveyor racks is also provided with a PLC controller electrically connected to each cooling fan and each photoelectric eye. During use, the photoelectric eye senses whether there are tiles passing by, so that the PLC controller can control the opening or closing of each cooling fan to realize the intelligent selection of the system, making the operation of the cooling fan more energy-efficient. However, in actual application, this solution still has the following shortcomings:

[0003] From the appendix of this patent document Figure 1 It can be seen that the tile conveying component used on the conveyor rack is a conveyor belt, and most conveyor belts are a whole surface and airtight conveyor belt structure, so that the wind output by the cooling fan can only blow to the top surface of the tile, while the bottom surface of the tile is difficult to have wind pass through. This will lead to prolonged cooling time of the tile and low cooling efficiency, so that the length of the conveyor line needs to be extended to ensure that there is enough time for the tiles to completely cool down. However, the extension of the conveyor line requires the addition of conveyor racks, photoelectric eyes and cooling fans, which will lead to increased energy consumption, insufficient energy saving, and occupy more site space.

[0004] Therefore, in view of the aforementioned deficiencies of the existing fan control device, it is very necessary to further improve its structure in order to better meet people's application needs. Utility Model Content

[0005] The purpose of the present utility model is to solve the above-mentioned problems and shortcomings, and to provide a fan control device, which can make the wind blown out by the first cooling fan pass through the top and bottom surfaces of the tiles respectively, so as to speed up the cooling efficiency of the tiles, reduce the time spent on cooling the tiles, and improve the cooling effect. It can also reduce the number of conveying units accordingly while ensuring that the tiles are completely cooled, thereby shortening the assembly line, thereby reducing energy consumption and reducing the occupied area of ​​the site space.

[0006] The technical solution of the present utility model is implemented as follows: a fan control device includes a plurality of conveying units connected side by side, the top of each conveying unit is provided with a first cooling fan with an air outlet arranged obliquely, and each conveying unit is provided with a tile induction switch device electrically connected to the first cooling fan, which is characterized in that the conveying unit includes a conveying frame and a conveying roller assembly arranged on the conveying frame, the conveying frame is provided with a first cooling air duct and a second cooling air duct respectively located above and below the conveying roller assembly; the conveying roller assembly includes a plurality of conveying rollers arranged side by side on the conveying frame, and a connecting gap connecting the first cooling air duct and the second cooling air duct is formed between each two adjacent conveying rollers; the first cooling fan and the tile induction switch device are both arranged in the first cooling air duct.

[0007] Preferably, the conveying frame is further provided with a first transverse flow limiting baffle located below the conveying roller assembly, and the second cooling air duct is formed between the first transverse flow limiting baffle and the conveying roller assembly.

[0008] Preferably, a second cooling fan is provided above the first cooling air duct for discharging air into the first cooling air duct, the air outlet of the second cooling fan is arranged vertically, and the second cooling fan is located on a side close to the air outlet of the first cooling fan.

[0009] Preferably, a second transverse flow limiting baffle is further provided above the first cooling air duct, and the second cooling fan is arranged on the second transverse flow limiting baffle.

[0010] Preferably, an obliquely arranged mounting frame is further provided in the first cooling air duct, and the first cooling fan is arranged on the mounting frame.

[0011] Preferably, the tile induction switch device includes a control switch, and a light emitter and a light receiver that are arranged in conjunction with each other. The light emitter and light receiver are respectively arranged on the left and right sides of the first cooling air duct. The light emitter, light receiver, first cooling fan and second cooling fan are respectively electrically connected to the control switch.

[0012] Preferably, vertical adjustment components for installing the light emitter and the light receiver are respectively provided on the left and right sides of the first cooling air duct, and the light emitter and the light receiver can vertically enter and exit the connecting gap through the two vertical adjustment components respectively.

[0013] Preferably, the two vertical adjustment components respectively include a fixing seat with a through hole, a vertical screw inserted in the through hole, a mounting portion arranged at the lower end of the vertical screw, and two locking nuts threaded on the vertical screw, so that the vertical screw is fixed on the fixing seat by clamping the two locking nuts; the two fixing seats are respectively arranged on the left and right sides of the first cooling air duct, and the light emitter and light receiver are respectively installed on the corresponding mounting portions.

[0014] The beneficial effects of the present invention are as follows: since a first cooling air duct is provided above the conveying roller assembly, a second cooling air duct is provided below the conveying roller assembly, and a connecting gap is formed between each two adjacent conveying rollers, the air blown out by the first cooling fan can flow through the first cooling air duct, the connecting gap, and the second cooling air duct respectively, so that the air energy can pass through the top and bottom surfaces of the tiles respectively, thereby accelerating the cooling efficiency of the tiles, reducing the time spent on cooling the tiles, and improving the cooling effect. It can also reduce the number of conveying units used accordingly while ensuring that the tiles are completely cooled, thereby shortening the production line, thereby reducing energy consumption and reducing the occupied space. In addition, since a connecting gap is formed between each two adjacent conveying rollers, there are multiple connecting gaps, so that the air blown out by the first cooling fan can freely shuttle between the first cooling air duct and the second cooling air duct, so that both the top and bottom surfaces of the tiles can obtain a very good cooling effect. At the same time, since each conveying unit is provided with a tile induction switch device electrically connected to the first cooling fan, each conveying unit is provided with a control device for separately turning on or off the first cooling fan, so that the first cooling fan on it will be turned on only when the tiles pass through the corresponding conveying unit, and all the first cooling fans will not be turned on at the same time. This can make the operation of each first cooling fan more energy-efficient and reduce energy waste. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] like Figure 1 and Figure 4As shown, the fan control device described in the utility model includes a plurality of conveying units 1 connected side by side, and the top of each conveying unit 1 is provided with a first cooling fan 2 with an air outlet arranged obliquely, and each conveying unit 1 is provided with a tile induction switch device 3 electrically connected to the first cooling fan 2. In order to achieve the purpose proposed by the utility model, the conveying unit 1 includes a conveying frame 11, and a conveying roller assembly 12 arranged on the conveying frame 11, and the conveying frame 11 is provided with a first cooling air duct 13 and a second cooling air duct 14 respectively located above and below the conveying roller assembly 12; the conveying roller assembly 12 includes a plurality of conveying rollers 121 arranged side by side on the conveying frame 11, and a connecting gap 122 is formed between each adjacent two conveying rollers 121 to connect the first cooling air duct 13 with the second cooling air duct 14; the first cooling fan 2 and the tile induction switch device 3 are both arranged in the first cooling air duct 13. The utility model can make the wind blown out by the first cooling fan 2 pass through the top and bottom surfaces of the tiles respectively, so as to speed up the cooling efficiency of the tiles, reduce the time spent on cooling the tiles, and improve the cooling effect. It can also reduce the number of conveying units accordingly while ensuring that the tiles are completely cooled, thereby shortening the assembly line, thereby reducing energy consumption and reducing the occupied area of ​​the site space.

[0022] In order to make it easier to make the second cooling duct 14 on the conveyor frame 11, as shown in FIG. Figure 2 and Figure 4 As shown, the conveyor frame 11 is further provided with a first transverse flow-limiting baffle 15 located below the conveyor roller assembly 12, and the second cooling air duct 14 is formed between the first transverse flow-limiting baffle 15 and the conveyor roller assembly 12. This prevents the air blown by the first cooling fan 2 from directly blowing onto the ground. Instead, the air passing through the connecting gap 122 is also utilized to form the second cooling air duct 14 to cool the bottom surface of the tiles. This allows a single first cooling fan 2 to cool both the top and bottom surfaces of the tiles, resulting in significant energy savings.

[0023] In order to further improve the cooling effect on tiles, Figure 4As shown, a second cooling fan 4 is provided above the first cooling duct 13 to discharge air into the first cooling duct 13. The air outlet of the second cooling fan 4 is arranged vertically, and the second cooling fan 4 is located on the side close to the air outlet of the first cooling fan 2. With this structural design, when in use, the first cooling fan 2 blows out oblique wind, which allows the blown wind to flow along the length of the first cooling duct 13. The vertical wind blown out by the second cooling fan 4 can collide with the oblique wind, causing the oblique wind and the vertical wind to roll back and forth in the first cooling duct 13 and the second cooling duct 14, thereby extending the time the wind stays in the first cooling duct 13 and the second cooling duct 14, thereby better removing heat from the top and bottom surfaces of the tiles and improving the cooling effect and efficiency. Moreover, by adding the second cooling fan 4, the air volume can also be increased to improve the cooling efficiency, and the cooling effect is very good.

[0024] like Figure 3 and Figure 4 As shown, a second transverse flow-limiting baffle 16 is further provided above the first cooling air duct 13, and the second cooling fan 4 is disposed on the second transverse flow-limiting baffle 16. The provision of the second transverse flow-limiting baffle 16 can limit the air from being discharged from above the first cooling air duct 13, thereby allowing the air to more easily roll back and forth between the first cooling air duct 13 and the second cooling air duct 14, thereby extending the air's residence time and improving the cooling effect and efficiency.

[0025] In order to further improve the installation structure of the first cooling fan 2, as Figure 2 and Figure 4 As shown, the first cooling duct 13 is further provided with an obliquely arranged mounting bracket 17, and the first cooling fan 2 is mounted on the mounting bracket 17. This structural design allows the first cooling fan 2 to be fixedly installed in the first cooling duct 13 in an obliquely arranged position, thereby facilitating the oblique arrangement of the first cooling fan 2. Specifically, both ends of the mounting bracket 17 extend and are fixed to the conveyor frame 11.

[0026] In order to further improve the structure of the tile induction switch device 3, as Figure 3 and Figure 4As shown, the tile induction switch device (3) includes a control switch (31), and a light emitter (32) and a light receiver (33) that are arranged together in a coordinated manner. The light emitter (32) and the light receiver (33) are respectively arranged on the left and right sides of the first cooling air duct (13). The light emitter (32), the light receiver (33), the first cooling fan (2), and the second cooling fan (4) are respectively electrically connected to the control switch (31). When in use, the light emitted by the light emitter 32 is directly emitted to the light receiver 33, forming a protective light curtain. When a tile passes by and blocks the light curtain, the light receiver 33 generates a light blocking signal and transmits it to the control switch 31. Then the control switch 31 brakes and controls the first cooling fan 2 and the second cooling fan 4, thereby achieving the purpose of automatically sensing and turning on the first cooling fan 2 and the second cooling fan 4. That is, the tile induction switch device 3 adopts an existing common and commonly used photoelectric protection device. Its specific connection structure and operating principle are not elaborated here. In actual application, the control switch 31 can be set on the conveying frame 11 or outside the conveying frame 11.

[0027] In order to make the tile induction switch device 3 be able to sense tiles of different thicknesses, such as Figure 3 As shown, vertical adjustment assemblies 18 for mounting the emitter 32 and the light receiver 33 are respectively provided on the left and right sides of the first cooling air duct 13. The emitter 32 and the light receiver 33 are respectively able to vertically enter and exit the communication gap 122 via the two vertical adjustment assemblies 18. This structural design allows the vertical height positions of the emitter 32 and the light receiver 33 to be adjusted accordingly based on the thickness of tiles, ensuring sensing accuracy, improving applicability, and making use more reliable. Furthermore, by allowing the emitter 32 and the light receiver 33 to vertically enter and exit the communication gap 122, thinner tiles can be sensed, further improving sensing accuracy.

[0028] like Figure 3 and Figure 4 As shown, preferably, the light emitter 32 and the light receiver 33 are respectively located in the first communication gap 122 near the input end of the conveyor roller assembly 12. This allows the light emitter 32 and the light receiver 33 to quickly sense the passage of tiles, and also allows the light emitter 32 and the light receiver 33 to be enclosed and not easily damaged by bumps, and also does not affect the rotation and conveying action of the conveyor roller 121, thereby highly reliable in use.

[0029] In order to further improve the structure of the vertical adjustment component 18, as shown Figure 5 and Figure 6As shown, the two vertical adjustment assemblies 18 each include a fixing base 182 with a through-hole 181, a vertical screw 184 inserted into the through-hole 181, a mounting portion 183 disposed at the lower end of the vertical screw 184, and two locking nuts 185 threaded onto the vertical screw 184. The fixing base 182 is clamped by the two locking nuts 185, thereby securing the vertical screw 184 to the fixing base 182. The two fixing bases 182 are respectively disposed on the left and right sides of the first cooling duct 13, and the light emitter 32 and the light receiver 33 are respectively mounted on the corresponding mounting portions 183. Specifically, the fixing bases 182 of the two vertical adjustment assemblies 18 are respectively disposed on the conveyor frame 11 on the left and right sides of the first cooling duct 13. During use, the vertical position of the vertical screw 184 can be adjusted by loosening the two locking nuts 185, and the vertical screw 184 can be fixed to the fixing base 182 by clamping the two locking nuts 185 on the fixing base 182. The installation of the mounting portion 183 facilitates the installation of the light emitter 32 or the light receiver 33. In actual use, the mounting portion 183 and the light emitter 32 or the light receiver 33 can be assembled together by means of snap-on mounting, buckling mounting, hanging mounting, sleeve mounting, screw locking, etc. Preferably, the mounting portion 183 is provided with a sleeve mounting hole, and the light emitter 32 and the light receiver 33 are respectively sleeved into the sleeve mounting holes of the corresponding mounting portion 183 to achieve the purpose of sleeve fixing.

[0030] In actual application, each conveying roller 121 is driven by a motor to perform a rotational conveying action. When all the conveying rollers 121 in a conveying roller assembly 12 are driven by only one motor, each two adjacent conveying rollers 121 are also connected to a transmission belt. In this way, multiple conveying rollers 121 can be driven by one motor to perform a rotational conveying action at the same time. Its specific structure and operating principle can also be referred to the patent document with Chinese patent application number 202420480757.4, entitled "A Construction Material Lifting Device". This solution records the specific structure and operating principle of driving multiple conveying rollers by one motor, which will not be elaborated here.

[0031] In actual application, each conveying unit 1 is provided with multiple first cooling fans 2, and each first cooling fan 2 is arranged along the axial direction of the conveying roller 121. There are also multiple second cooling fans 4, and the number of the second cooling fans 4 is the same as the number of the first cooling fans 2. At the same time, the arrangement position of each second cooling fan 4 is opposite to the arrangement position of each first cooling fan 2.
