Description

Technical Field

[0001] This utility model relates to the field of flooring processing technology, and in particular to a flooring UV curing device. Background Technology

[0002] In the flooring production process, to improve the wear resistance, corrosion resistance, and aesthetics of the flooring surface, a UV coating is usually applied to the surface, and then cured quickly using ultraviolet light through a UV curing device. Due to its advantages such as fast curing speed, low energy consumption, and good environmental friendliness, UV curing technology has become one of the key processes in the flooring manufacturing industry.

[0003] For example, a UV curing device for paint in wood flooring production, disclosed in CN218574166U, includes a support frame, conveyor belt, curing chamber, feeding frame, adjustment components, and UV lamps. The device allows adjustment of the distance between the UV lamps and the wood flooring via the adjustment components, thereby enabling the curing device to adjust the irradiation height of the UV lamps according to different specifications of wood flooring, thus improving the curing efficiency of the paint surface.

[0004] However, the above-mentioned solution has shortcomings in use. When the coating cures rapidly under ultraviolet irradiation, a small amount of incompletely reacted paint mist particles evaporate. These particles diffuse with the airflow within the curing chamber and easily adhere to the surface of the UV lamp. Over time, this accumulates into a dense layer of dirt, which directly blocks the UV lamp's UV transmission path, leading to a decrease in UV irradiation intensity. This, in turn, reduces the curing efficiency of the floor surface, and in severe cases, may even result in incomplete curing in certain areas, affecting the overall processing quality of the floor. Therefore, a floor UV curing device needs to be designed.

[0005] 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

[0006] This utility model provides a floor UV curing device to solve the problem that paint mist particles generated during paint curing adhere to the UV lamp, forming a dirt layer, which leads to UV attenuation, reduced curing efficiency, or even incomplete curing in some areas, thus affecting quality.

The two sets of mounting plates are arranged symmetrically from left to right, and a UV lamp is installed between the two sets of mounting plates by fasteners. The irradiation direction of the UV lamp is perpendicular to the conveying surface of the conveyor.

[0009] Furthermore, the adjustment unit consists of a support group and an adjustment group. The adjustment group includes two sets of fixing plates symmetrically installed at the junction of the frame of the conveyor and the inner wall of the curing box. The two sets of fixing plates are parallel to each other, and two vertically arranged and parallel guide rods are fixed between the two sets of fixing plates.

[0010] A lead screw is mounted on a bearing between the two sets of fixed plates. The lead screw is arranged parallel to the guide rod. A drive motor is installed on the top outer wall of the curing box corresponding to the end of the lead screw. The output shaft of the drive motor is rigidly connected to one end of the lead screw via a coupling.

[0011] Furthermore, the support assembly includes two sets of fixing plates symmetrically fixedly installed between the frame of the conveyor and the inner wall of the curing chamber. Guide rods are also fixedly installed between the two sets of fixing plates. The guide rods are aligned with the first guide rod. The two sets of mounting plates of the curing part are slidably sleeved on the guide rods of the support assembly and the first guide rod of the adjustment assembly, respectively, forming a stable double-set guide support structure. The mounting plate sleeved on the first guide rod of the adjustment assembly has a threaded hole at the corresponding position that matches the first lead screw, and is threadedly connected to the first lead screw.

[0012] Furthermore, the suction unit includes two sets of suction pipes parallel to the curing chamber and installed on the top of the curing chamber through flanges. Each set of suction pipes has two vertically arranged risers connected vertically to its body. The bottom of the risers passes through the top plate of the curing chamber and extends into the internal space. The bottom of the risers is connected to an absorption cover through a telescopic tube. The bottom of the absorption cover is provided with a grid plate with an inclined downward opening. The grid plate is detachably connected to the absorption cover by fasteners. One end of the suction pipe is connected to an external suction device through a hose connector. The absorption cover is rigidly connected to the mounting plate through a fixing strip.

[0013] Furthermore, the fixing part one consists of a first half-clamping ring and a second half-clamping ring that are hinged to each other.

A protrusion adapted to the waist groove is installed on the inner wall of the movable sleeve. The protrusion is embedded in the waist groove and threadedly connected to the lead screw.

[0015] Furthermore, the other end of the guide rod and the hollow rod is connected to a collection box via a second fixing part with a similar structure to the first fixing part. The second fixing part is composed of interlocking clamping ring components. The collection box is a box structure with an open top. The bottom surface of the opening slot in the collection box is lower than the bottom surface of the limiting plate, forming a height difference.

[0016] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0017] A floor UV curing device creates a stable curing environment through a curing component. An adjustment unit flexibly adapts to flooring of varying thicknesses, ensuring adequate UV irradiation distance and improving curing uniformity. A suction unit efficiently captures paint mist using negative pressure, promptly removing it from the curing chamber via a suction pipe, riser, and absorption hood, minimizing particle residue. A cleaning component, utilizing a support plate and guide rods, along with a reciprocating cleaning unit, periodically removes paint mist and dirt adhering to the UV lamp surface, maintaining stable UV transmittance. The combined effect of these three components prevents long-term paint mist accumulation from forming a dirt layer that obstructs the UV lamp and reduces irradiation intensity. Furthermore, adjustments and cleaning ensure efficient and high-quality curing of the floor surface. Attached Figure Description

[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0029] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0030] Reference Figures 1-6 As shown, this utility model embodiment provides a floor UV curing device, including a conveying component 1, which includes a conveyor 11, and the conveyor 11 is used to carry flooring of different specifications and realize continuous conveying. A curing component 2 is installed on the conveyor 11, and the curing component 2 includes a curing box 21 fixedly installed on the conveyor 11. The curing box 21 adopts a sealed box structure, and its two side walls are provided with openings 22 corresponding to the conveying surface of the conveyor 11.

[0031] The curing chamber 21 is equipped with a curing section 25 for curing the coating on the floor surface. The curing section 25 includes two sets of mounting plates 251 located at the upper end of the conveyor 11 and inside the curing chamber 21. The two sets of mounting plates 251 are arranged symmetrically from left to right, and a UV lamp 252 is installed between the two sets of mounting plates 251 by fasteners. The irradiation direction of the UV lamp 252 is perpendicular to the conveying surface of the conveyor 11, which can provide uniform and stable ultraviolet irradiation to the UV coating on the floor surface, ensuring that the coating is cured and formed quickly.

[0032] In this application, to achieve intelligent operation and energy-saving control of the equipment, an infrared sensor is embedded in the top position near the entrance end inside the curing chamber 21. The sensing probe of the infrared sensor is tilted towards the conveying surface of the conveyor 11, and its sensing range can cover the entire area inside the opening 22, which can detect whether the floor has entered the curing chamber 21. At the same time, the infrared sensor is connected to the controller 12 set on the frame of the conveyor 11 through a shielded cable. The controller 12 is used to receive the signal from the infrared sensor. When the floor is sensed to have entered the curing chamber 21, the UV lamp 252 is triggered to start and the conveying speed of the conveyor 11 is adjusted synchronously.

[0033] To accommodate the curing requirements of flooring of different thicknesses, an adjustment unit 24 for adjusting the height of the UV lamp 252 is provided on the conveyor 11 and inside the curing chamber 21. The adjustment unit 24 consists of a support group and an adjustment group. The adjustment group includes two sets of fixing plates 241 symmetrically fixed at the junction of the conveyor 11 frame and the inner wall of the curing chamber 21. The two sets of fixing plates 241 are horizontally parallel. Two vertically arranged and parallel guide rods 242 are fixed between the two sets of fixing plates 241 to provide guidance for the movement of subsequent components.

[0034] Meanwhile, a lead screw 243 is installed between the two sets of fixed plates 241. The lead screw 243 is arranged in parallel with the guide rod 242. A drive motor (not shown in the figure) is fixedly installed on the top outer wall of the curing box 21 at the end position of the lead screw 243. The output shaft of the drive motor is rigidly connected to one end of the lead screw 243 through a coupling. The motor can drive the lead screw 243 to rotate when it is running.

[0035] The support assembly includes two sets of fixed plates 244 symmetrically fixed between the conveyor frame 11 and the inner wall of the curing chamber 21. A guide rod (not shown in the figure) is also fixedly installed between the two sets of fixed plates 244. The guide rod 244 is aligned with the guide rod 242. Two sets of mounting plates 251 of the curing section 25 are slidably sleeved on the guide rod 242 of the support assembly and the guide rod 242 of the adjustment assembly, respectively, forming a stable double-set guide support structure. The mounting plate 251 sleeved on the guide rod 242 of the adjustment assembly has a threaded hole at a corresponding position that matches the lead screw 243, and is threadedly connected to the lead screw 243. When the drive motor rotates the lead screw 243, the mounting plate 251 can move smoothly along the direction of the guide rod, thereby adjusting the height of the UV lamp 252 to meet the ultraviolet irradiation distance requirements for different floor curing processes.

[0036] To solve the problem of paint mist particle pollution during UV curing, a suction unit 23 is provided on the top and side wall of the curing chamber 21. The suction unit 23 includes two sets of suction pipes 231 that are parallel to the curing chamber 21 and fixedly installed on the top of the curing chamber 21 through flanges. Each set of suction pipes 231 has two vertically arranged upright pipes 232 connected vertically on its body, and the bottom of the upright pipes 232 extends through the top plate of the curing chamber 21 and into the internal space.

[0037] The bottom end of the riser 232 is connected to the absorption hood 234 via the telescopic pipe 233. The bottom of the absorption hood 234 is provided with a downward-sloping grid plate 235. The grid plate 235 is detachably connected to the absorption hood 234 by fasteners. Its tilt angle guides the smooth intake of paint mist particles. At the same time, one end of the suction pipe 231 is connected to an external suction device (such as an industrial dust collector) via a hose connector. When the suction device is working, the negative pressure is used to make the paint mist in the curing box 21 enter the absorption hood 234 through the grid plate 235, and then collect through the riser 232 to the suction pipe 231, and finally be sucked to the external purification system, effectively reducing the residual accumulation of paint mist in the box.

[0038] It should be noted that, in order to ensure that the absorption cover 234 and the UV lamp 252 always maintain the best relative position relationship during the height adjustment process, the absorption cover 234 is rigidly connected to the mounting plate 251 through the fixing strip. When the drive motor of the adjustment part 24 drives the lead screw 243 to rotate, so that the mounting plate 251 moves up and down along the guide rod 242, the fixing strip can synchronously transmit the displacement to the absorption cover 234.

[0039] To solve the problem of cleaning paint mist and dirt on the surface of UV lamp 252, a cleaning component 3 is configured inside the curing box 21 between the two sets of mounting plates 251. The cleaning component 3 includes a support plate 31 fixedly installed on the opposite sides of the two sets of mounting plates 251. A guide rod 32 and a hollow rod 33 are fixed at the parallel ends of the two sets of support plates 31. The guide rod 32 is used to provide stable guidance, and a movable sleeve 34 is slidably sleeved on both the guide rod 32 and the hollow rod 33. The movable sleeve 34 is adapted to slide along the straight direction of the guide rod 32 and the hollow rod 33.

[0040] Two sets of movable sleeves 34 are connected to the cleaning part through a fixed part one. The fixed part one consists of a semi-clamping ring 36 and a semi-clamping ring 37 that are hinged to each other. The semi-clamping ring 36 and the semi-clamping ring 37 are wrapped around the outer periphery of the movable sleeve 34. A rotating shaft 38 is movably connected to the semi-clamping ring 36. The rotating shaft 38 is a stainless steel screw. The semi-clamping ring 37 has a matching opening groove (not shown in the figure) at the corresponding position. When the semi-clamping ring is closed around the pin, the rotating shaft 38 can be inserted into the opening groove. Then, a nut 39 is threaded to the exposed end of the rotating shaft 38. After tightening, the semi-clamping ring 36 and the semi-clamping ring 37 can be tightly locked together, thereby firmly clamping the cleaning part.

[0041] The cleaning unit includes a limiting plate 311 connected between two sets of fixing parts 36 by a semi-clamping ring 36. A cleaning block 312 is connected to the limiting plate 311 by bolts 313. The cleaning block 312 adopts a composite structure of a support block and a sponge block. The sponge block is a solvent-resistant PU sponge, which ensures that when wiping the surface of the UV lamp 252, it can effectively adsorb paint mist particles and dissolve light dirt without scratching the shell of the UV lamp 252, ensuring stable ultraviolet transmission performance and achieving flexible and efficient cleaning of the surface of the UV lamp 252.

[0042] To drive the sponge block to reciprocate wiping the surface of the UV lamp 252, thus achieving automated cleaning operations, such as... Figures 5-6 As shown, a drive unit is installed on the side of a set of support plates 31. The drive unit includes a stepper motor 35 fixedly installed on the side of the set of support plates 31. The output end of the motor 35 is connected to a lead screw 331 via a coupling. Meanwhile, a waist groove (not shown in the figure) is opened along the length direction on the side wall of the hollow rod 33. At the same time, a protrusion that matches the waist groove is fixedly installed on the inner wall of the movable sleeve 34. The protrusion is embedded in the waist groove and threadedly connected to the lead screw 331. When the motor 35 drives the lead screw 331 to rotate forward and backward, the protrusion can drive the movable sleeve 34 to slide smoothly along the guide rod 32 and the hollow rod 33, thereby pulling the cleaning block 312 to move back and forth.

[0043] At the other end of the guide rod 32 and the hollow rod 33, a collection box 315 is connected by a second fixing part 314 with a similar structure to the first fixing part. The second fixing part 314 is also composed of interlocking clamping rings, which facilitates quick assembly and disassembly of the collection box 315. The collection box 315 is a box structure with an open top. The bottom surface of the opening slot is lower than the bottom surface of the limiting plate 311, forming a height difference. When the cleaning block 312 wipes the surface of the UV lamp 252 to one end near the collection box 315, as the movable sleeve 34 moves, the paint mist dirt carried by the cleaning block 312 can fall into the collection box 315 due to gravity and inertia, thus achieving centralized collection of dirt. The collection box 315 can be cleaned regularly to ensure the continuous and efficient operation of the cleaning components, maintain the cleanliness of the UV lamp 252 surface, and ensure stable ultraviolet transmittance.

[0044] It should be noted that the setting of cleaning component 3 does not affect the normal use of UV lamp 252. Specifically, all components of cleaning component 3 are installed in the space between the two sets of mounting plates 251. Its guide rod 32 and hollow rod 33 maintain a safe distance from the mounting plane of UV lamp 252 to avoid interference during movement. In the initial state, the sponge block and the collection box 315 are located at the two ends of the guide rod 32 and will not block the path of ultraviolet radiation.

[0045] Working principle: When the equipment starts running, the conveyor 11 starts and transports the flooring to be cured to the entrance of the curing chamber 21. At this time, the infrared sensor near the entrance of the curing chamber 21 monitors in real time. Once the flooring is detected to have entered the curing chamber 21, a signal is sent to the controller 12 through the shielded cable. After receiving the signal, the controller 12 triggers the UV lamp 252 to start, emitting ultraviolet light in preparation for the curing operation. On the other hand, according to the preset program or flooring parameters, the conveyor speed of the conveyor 11 is adjusted synchronously to ensure that the flooring has a reasonable residence time in the curing chamber 21, preparing for subsequent uniform curing.

[0046] Meanwhile, if the height of the UV lamp 252 needs to be adjusted to match the floor thickness, the drive motor will rotate, causing the lead screw 243 to rotate. The mounting plate 251, which is threaded to the lead screw 243, will move smoothly along the guide rod 242, thereby adjusting the UV lamp 252 to a suitable height to ensure that the ultraviolet irradiation distance matches the floor and to ensure the curing effect.

[0047] After the floor enters the curing chamber 21, the ultraviolet rays emitted by the UV lamp 252 vertically irradiate the floor surface to cure the UV coating and make the coating form quickly. During this process, the suction unit 23 works simultaneously. The external suction equipment generates negative pressure through the suction pipe 231 and the riser pipe 232. The paint mist particles generated in the curing chamber 21 due to the curing of the coating are sucked in through the grid plate 235 with the bottom of the absorption cover 234 that is inclined downward. They are collected along the riser pipe 232 and then collected in the suction pipe 231. Finally, they are sucked to the external purification system, which effectively reduces the paint mist residue in the curing chamber 21 and prevents it from adhering and affecting the equipment components.

[0048] If the accumulated paint mist and dirt on the surface of the UV lamp 252 needs to be cleaned after the equipment has been running for a period of time, the cleaning component 3 is started. The stepper motor 35 drives the lead screw 331 to rotate forward and backward. The protrusion on the inner wall of the movable sleeve 34 slides along the waist groove of the hollow rod 33 and engages with the thread of the lead screw 331. This causes the movable sleeve 34 to move back and forth along the guide rod 32 and the hollow rod 33, thereby pulling the cleaning block 312 to wipe the surface of the UV lamp 252. The paint mist and dirt adsorbed by the sponge block of the cleaning block 312 falls into the collection box 315 due to the height difference formed by the bottom surface of the opening groove of the collection box 315 being lower than the bottom surface of the limiting plate 311, thus achieving centralized collection of dirt. The collection box 315 can be cleaned periodically afterward to ensure that the cleaning component 3 continues to work effectively, maintains the cleanliness of the UV lamp 252 surface, ensures stable ultraviolet transmittance, and does not affect the curing operation.

[0049] When the floor has completely passed through the curing chamber 21, the infrared sensor detects that the floor has left and sends a signal to the controller 12 again. The controller 12 controls the UV lamp 252 to turn off with a delay (the delay time can be preset). At the same time, the conveyor 11 resumes its initial or adapted conveying speed for the next operation. If the height of the UV lamp 252 has been adjusted or the cleaning component 3 has been operated, it returns to the initial standby state under the action of the controller 12 or its own mechanical structure. For example, the drive motor drives the lead screw 243 to reverse, so that the mounting plate 251 is reset; the stepper motor 35 stops running, and the cleaning block 312 returns to the initial position at one end of the guide rod 32, waiting for the next round of floor curing operation cycle, ensuring that the equipment continuously and stably performs UV curing treatment on subsequent floors.
