Description

Technical Field

[0001] This application relates to the field of industrial dust removal equipment technology, specifically a reciprocating flame dust removal device. Background Technology

[0002] Existing flame dust removal devices are mainly used to burn, vaporize, or carbonize impurities, oil stains, coatings, etc. on the surface of workpieces through the high temperature of the flame, thereby cleaning the workpiece surface, improving the surface quality of the workpiece, and providing good surface conditions for subsequent processing procedures (such as painting, welding, etc.).

[0003] However, in actual industrial production, different workpieces vary in size and shape, and existing flame dust removal devices often cannot be flexibly adjusted according to the characteristics of different workpieces. For example, the fixed installation of the flame-spraying components in some devices cannot adapt to the dust removal needs of workpieces of different heights, which may result in the flame not being accurately sprayed onto the workpiece surface, resulting in poor dust removal effect; for some complex-shaped workpieces that require multi-directional dust removal, the existing fixed motion mode is difficult to achieve comprehensive and uniform dust removal treatment, resulting in some areas not being effectively cleaned;

[0004] Furthermore, existing flame dust removal devices have shortcomings in terms of automation control. On the one hand, they cannot automatically detect the position of the workpiece, requiring manual judgment to determine whether the workpiece has reached the dust removal area and to manually start the device. This not only increases labor costs but also easily leads to operational errors, resulting in inaccurate dust removal timing and affecting dust removal quality. On the other hand, the lack of automatic control over the stroke of the flame-spraying components may cause them to exceed their reasonable range of motion, leading to equipment malfunctions or safety hazards, such as the flame-spraying components colliding with other parts of the device and causing equipment damage.

[0005] Therefore, it is necessary to provide a reciprocating flame dust removal device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] The purpose of this invention is to provide a reciprocating flame dust removal device to solve the problems mentioned in the background art.

[0008] The technical solution adopted by this application to solve its technical problem is:

[0009] A reciprocating flame dust removal device includes a suspension mounted on a transport device. A drive assembly is rotatably mounted inside the suspension. Two fixing assemblies are fixedly mounted on the belt of the drive assembly, and the two fixing assemblies are symmetrically arranged on the side wall of the belt. The two fixing assemblies are staggered and move in the suspension as the belt of the drive assembly rotates.

[0010] Two flame-spraying components are slidably mounted on a fixed component, and the two flame-spraying components perform flame dust removal on the workpiece as the fixed component moves.

[0011] Two guide components, with the top ends of the fixing component respectively mounted on the two guide components;

[0012] Position sensors are respectively installed on the inner sidewalls of the suspension.

[0013] Preferably, the drive assembly further includes a drive wheel, a driven wheel, and a drive device. The drive wheel and the driven wheel are rotatably mounted on the inner top surface of the suspension. The drive wheel drives the driven wheel through a belt. The drive device is mounted on the top surface of the suspension and provides rotational power to the drive wheel.

[0014] Preferably, the fixing component includes a first clamping block, a second clamping block, and a height adjustment mechanism. The side walls of the first and second clamping blocks are provided with clamping grooves. The first and second clamping blocks are clamped and fixed to the side wall of the belt through the clamping grooves. The bottom surface of the second clamping block is fixedly connected to the height adjustment mechanism, and the flame-throwing component is mounted on the height adjustment mechanism.

[0015] Preferably, the height adjustment mechanism includes a vertical plate, a slider, and a fixed cylinder. The top of the vertical plate is fixed to the second clamping block. A groove is provided on the side wall of the vertical plate. The slider is slidably installed in the groove. A threaded hole is provided on one side wall of the slider. A knob is threaded into the threaded hole. A pressure plate is sleeved on the side wall of the knob. Both ends of the pressure plate abut against the side wall of the vertical plate. The fixed cylinder is fixedly connected to the other side wall of the slider. The flame-throwing assembly is installed on the fixed cylinder.

[0016] Preferably, the flamethrower assembly includes a flamethrower and an igniter, which are respectively installed and sleeved in a fixed cylinder, with the ignition end of the igniter located on the exhaust port side of the bottom of the flamethrower.

[0017] Preferably, the guide assembly includes a fixed plate, two cross plates, and a slide. The fixed plate is fixedly installed on the inner top surface of the suspension. The two cross plates are respectively installed on the side walls of the suspension. The end faces of the slide are respectively rotatably mounted with pulleys. The pulleys are slidably connected on the top and bottom surfaces of the cross plates. The bottom of the slide is fixedly connected by a connecting plate. The bottom surface of the connecting plate is fixedly connected to a second mounting plate. The top surface of the second clamping block is fixedly connected to a first mounting plate. The first mounting plate and the second mounting plate are installed in a staggered manner.

[0018] Preferably, limiters are installed on the inner top surfaces of the suspension located inside the driving wheel and the driven wheel, respectively, and a limit plate is fixedly connected to the side wall of the first clamping block;

[0019] When the first clamping block moves with the belt and approaches the driving wheel or driven wheel, the side wall of the limiting plate comes into contact with the limiting sensor element.

[0020] The beneficial effects of this application are:

[0021] 1. The fixing component in this technical solution includes a height adjustment mechanism. By rotating the knob, the friction between the pressure plate and the vertical plate can be changed, thereby moving the slider in the groove and precisely adjusting the height of the fixing cylinder and the flame-spraying component. The position of the flame-spraying component can be flexibly adjusted according to the workpiece of different heights to ensure that the flame is accurately sprayed onto the workpiece surface. At the same time, the two flame-spraying components work simultaneously, which can cover a larger area than a single flame-spraying component. More parts of the workpiece can be flame-dust-removed in one stroke, reducing the time and number of dust removals required, thereby improving the overall dust removal efficiency and completing the dust removal treatment of the workpiece surface more quickly to meet the needs of large-scale production.

[0022] 2. Using infrared transmitters and receivers installed on the side walls of the suspension as position sensors, when the transport device passes under the suspension carrying a workpiece, the infrared light is blocked by the workpiece, automatically determining that the workpiece has entered the dust removal area and triggering the reciprocating flame dust removal device to operate. Simultaneously, combined with the design of limiters and limit plates, the drive motor can be automatically controlled to stop or reverse, limiting the stroke of the flame-spraying components. This eliminates the need for real-time monitoring and manual operation, reducing human intervention and operational errors, improving the efficiency and stability of flame dust removal, and lowering labor costs and equipment failure risks.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0043] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0044] Please see Figure 1-5 The embodiments provided by this utility model are as follows:

[0045] like Figure 1 As shown, a reciprocating flame dust removal device 2 includes a suspension 21 installed on a transport device 1. A drive assembly 22 is rotatably installed inside the suspension 21. Two fixing components 25 are fixedly installed on the belt 222 of the drive assembly 22. The two fixing components 25 are symmetrically arranged on the side wall of the belt 222 and are staggered. The two fixing components 25 move in the suspension 21 as the belt 222 of the drive assembly 22 rotates, thus building a basic framework for subsequent flame dust removal work and allowing the flame-spraying assembly 26 to move within the specific space of the suspension 21, which facilitates the flame dust removal operation on the workpiece 3 on the transport device 1.

[0046] like Figure 2 and Figure 3As shown, the drive assembly 22 also includes a drive wheel 223, a driven wheel 221, and a drive device. The drive wheel 223 and the driven wheel 221 are rotatably mounted on the inner top surface of the suspension 21. The drive wheel 223 drives the driven wheel 221 through a belt 222. The drive device is mounted on the top surface of the suspension 21 and provides rotational power to the drive wheel 223. The drive device can be composed of a gear set 224 and a drive motor 225. The drive motor 225 is of model MDMA102A1 and is mounted on the housing of the gear set 224. The drive motor 225 outputs power to the gear set 224. The output shaft is keyed to the input shaft of the gear set 224, and the output shaft of the gear set 224 is keyed to the drive wheel 223 via a drive rod. The drive motor 225 drives multiple gear sets 224 in the gear set 224 to rotate, thereby driving the drive wheel 223 to rotate in the suspension 21 and providing rotational power to the drive wheel 223 so that the belt 222 rotates on the drive wheel 223 and the driven wheel 221. By controlling the forward and reverse rotation of the drive motor 225, the two fixed components 25 are driven to move in opposite directions on the belt 222 to achieve the reciprocating motion required for flame dust removal.

[0047] like Figure 4 As shown, in order to fix the flame-spraying assembly 26 and adjust the height of the workpiece 3 for flame dust removal as needed, the fixing assembly 25 includes a first clamping block 251, a second clamping block 252, and a height adjustment mechanism. The side walls of the first clamping block 251 and the second clamping block 252 are provided with clamping grooves 254. The first clamping block 251 and the second clamping block 252 are clamped and fixed to the side wall of the belt 222 through the clamping grooves 254. The bottom surface of the second clamping block 252 is fixedly connected to the height adjustment mechanism. The flame-spraying assembly 26 is mounted on the height adjustment mechanism. The height adjustment mechanism includes a vertical plate 256, a slider 258, and a fixing cylinder 2511. The top of the vertical plate 256 is fixed to the second clamping block 252, and the side wall of the vertical plate 256 is provided with a sliding groove. 257. The slider 258 is slidably installed in the slide groove 257. A threaded hole is opened on one side wall of the slider 258, and a knob 259 is threadedly connected in the threaded hole. A pressure plate 2510 is sleeved on the side wall of the knob 259. The two ends of the pressure plate 2510 abut against the side wall of the vertical plate 256. The fixed cylinder 2511 is fixedly connected to the other side wall of the slider 258. The flame-spraying assembly 26 is installed on the fixed cylinder 2511. When the knob 259 is rotated, the friction between the pressure plate 2510 and the vertical plate 256 changes, which can fix or move the position of the slider 258, thereby adjusting the fixed cylinder 2511, and thus flexibly adjusting the height of the flame-spraying assembly 26 to the workpiece 3, ensuring that the flame can accurately act on the surface of the workpiece 3, and improving the effect and applicability of flame dust removal.

[0048] Two flame-spraying components 26 are slidably mounted on the fixed component 25. The two flame-spraying components 26 perform flame dust removal on the workpiece 3 as the fixed component 25 moves. Specifically, the flame-spraying component 26 includes a flame-sprayer 261 and an igniter 262. The flame-sprayer 261 and the igniter 262 are respectively installed and sleeved in the fixed cylinder 2511. The ignition end of the igniter 262 is located on the exhaust port side of the bottom end of the flame-sprayer 261. When the fixed component 25 moves to the appropriate position, the flame-sprayer 261 sprays out gas, and the igniter 262 ignites the gas to generate a flame to remove dust from the workpiece 3.

[0049] To ensure the stability of the flame-throwing assembly 26 during movement with the fixed assembly 25 and to ensure it moves along a designated path, the top of the fixed assembly 25 is respectively mounted on two guide assemblies 27. The guide assembly 27 includes a fixed plate 271, two horizontal plates 272, and a slide 273. The fixed plate 271 is fixedly mounted on the inner top surface of the suspension 21. The two horizontal plates 272 are respectively mounted on the side walls of the suspension 21. The end faces of the slide 273 are respectively rotatably mounted with pulleys 274. The pulleys 274 are slidably connected on the top and bottom surfaces of the horizontal plates 272. The bottom of the slide 273 is fixedly connected through a connecting plate 275. The bottom surface of the connecting plate 275 is fixedly connected to a second mounting plate 276. The top surface of the second clamping block 252 is fixedly connected to a first mounting plate 255. The first mounting plate 255 and the second mounting plate 276 are installed in a staggered manner.

[0050] When the fixed component 25 moves, the first mounting plate 255 drives the second mounting plate 276, which in turn drives the slide 273 to move. The pulley 274 slides on the cross plate 272 to provide guidance and support, ensuring that the flame-spraying component 26 does not deviate or shake during movement, so that the flame can accurately act on the surface of the workpiece 3, improving the accuracy and effect of flame dust removal.

[0051] like Figure 2 As shown, position sensors 23 are respectively installed on the inner side walls of the suspension 21. Position sensors 23 can be infrared transmitters and receivers. The infrared transmitters and receivers are respectively installed on the inner side walls of the suspension 21, so that when the transport device 1 transports the workpiece 3 under the suspension 21, the infrared rays emitted by the infrared transmitter are blocked by the workpiece 3, and the receiver cannot receive the infrared signal, thereby determining that the workpiece 3 has fallen into the flame dust removal area, thereby triggering the reciprocating flame dust removal device 2 to work and perform flame dust removal on the workpiece 3.

[0052] like Figure 2As shown, limiters 24 are respectively installed on the inner top surface of the suspension 21 located inside the drive wheel 223 and the driven wheel 221. The side wall of the first clamping block 251 is fixedly connected to the limit plate 253. When the first clamping block 251 moves with the belt 222 and approaches the drive wheel 223 or the driven wheel 221, the side wall of the limit plate 253 abuts against the sensing element of the limiter 24 to limit the travel of the two flame-throwing assemblies 26 on the suspension 21.

[0053] Control principle of reciprocating flame dust removal device 2:

[0054] The reciprocating flame dust removal device 2 is also equipped with a driver, which can be model X2MH010A-N2LN. When the transport device 1 carries the workpiece 3 under the suspension 21, the workpiece 3 will block the infrared rays emitted by the infrared emitter, preventing the receiver from receiving the signal. The position sensor 23 transmits this signal change to the driver. After receiving the signal, the driver determines that the workpiece 3 has entered the flame dust removal area and then issues a command to start the drive motor 225, causing the drive assembly 22 to drive the fixing assembly 25 and the flame-spraying assembly 26 to start working and perform flame dust removal on the workpiece 3.

[0055] When the first clamping block 251 moves close to the driving wheel 223 or driven wheel 221 along with the belt 222, the limiting plate 253 will contact the sensing element of the limiter 24. The limiter 24 transmits this contact signal to the driver. After receiving the signal, the driver controls the drive motor 225 to stop its current rotation direction and reverses the drive motor 225 to control the reciprocating motion of the flame-spraying assembly 26. This also limits the travel of the flame-spraying assembly 26 on the suspension 21 so that it does not exceed the specified range, ensuring the safe and stable operation of the equipment.

[0056] When the driver starts the drive motor 225 according to the signal from the position sensor 23, it simultaneously sends a start signal to the igniter 262 and the flamethrower 261. For the igniter 262, its control circuit may include a power supply module and a trigger module. The power supply module provides the required electrical energy to the igniter 262. The trigger module generates a high-voltage pulse according to the signal received by the driver from the position sensor 23, causing the ignition end to generate a spark to ignite the gas in the flamethrower 261. The flamethrower 261 includes a power supply module, a gas supply control module, and a flow regulation module. The power supply module provides power to the control elements of the flamethrower 261. The gas supply control module controls the supply and cutoff of gas. The flow regulation module can adjust the gas ejection flow rate according to actual needs to control the size and intensity of the flame. The igniter 262 and the flamethrower 261 are both prior art known to those skilled in the art and will not be described in detail here.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
