Description

Technical Field

[0001] The present invention relates to the technical field of UV dryers, and in particular to an omnidirectional UV dryer for thermal transfer films and a drying method. Background Art

[0002] When UV coating is cured on the board, natural air drying is often used. However, this UV coating curing method is time-consuming, costly, and has low production efficiency. In addition, the hardness of the UV coating on the surface of the board after air drying is low, which affects the subsequent production and processing of the board. Therefore, a UV dryer is used in the existing technology to dry the UV coating.

[0003] According to the publication (announcement) number: CN105478320A, the publication (announcement) date: 2016-04-13, a UV dryer is disclosed. Compared with the existing technology, the present invention can perform a full range of instant drying treatment on the plate after coating, ensuring the uniformity and integrity of the coating surface drying, greatly improving the hardening and curing effect and durability of the coating surface, and the coating surface dries quickly, efficiently, and with a high degree of automation, and is also easy to follow up on production and processing.

[0004] According to the publication (announcement) number: CN109158278A, the publication (announcement) date: 2019-01-08, an LED-UV curing dryer is disclosed. This solution improves the curing efficiency through a workpiece conveying mechanism, a lighting mechanism, a water cooling mechanism, and uses LED-UV curing technology. It does not require preheating operation and can complete the curing of UV paint within seconds.

[0005] In the prior art including the above-mentioned patent, when the plate is manually placed on the conveyor belt of the UV dryer, the conveyor belt transports the plate to the bottom of the drying box on the UV dryer, and the UV drying lamp in the drying box dries the UV coating. After the plate is placed on the conveyor belt, the back of the plate must be in contact with the surface of the conveyor belt. Although only the side of the plate coated with a thicker UV coating needs to be dried during drying, the back of the plate cannot be heated normally, which can easily affect the heat transfer through the inside of the plate to the side coated with UV coating, so that the back of the UV coating layer is heated less, and the all-round drying effect of the UV coating on the plate cannot be achieved, which affects the overall drying effect of the UV coating on the plate, and can easily cause the hardness of the UV coating to increase slowly, consuming more additional drying resources.

[0041] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0042] like Figure 1-10 As shown, a thermal transfer film omnidirectional UV drying machine includes a drying machine 1 provided with a conveyor belt 11 and a drying box 12, and also includes a plurality of symmetrically arranged on the conveyor belt 11:

[0043] The slide 2 and the plate frame 3 are kept moving closer to or farther away from each other, and a first elastic member 22 is provided between the two;

[0044] The plate shaft 33 provided on the plate frame 3 is rotated. A pair of vertically arranged straps 331 are provided on the plate shaft 33. The straps 331 are deflected at a predetermined angle and cooperate with the slide 2 and the plate frame 3 in the separated state.

[0045] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 5 and Figure 7As shown, the conveyor belt 11 is installed on the dryer 1 through a support frame, and a conveying baffle 111 is fixedly installed on the support frame, and the conveying baffle 111 is symmetrically arranged on both sides of the conveyor belt 11, and the conveyor belt 11 remains uniform during operation; the slide 2 is fixedly installed on the surface of the conveyor belt 11, and the conveyor belt 11 drives the slide 2 and the plate rack 3 to move when it is working, and when the slide 2 reaches the bottom of the drying box 12, the conveyor belt 11 stops working and stops for 40 minutes to 100 minutes, and the method of processing the drying time of the plate is the existing technology and will not be repeated here.

[0046] Furthermore, a main slide 211 and an auxiliary slide 311 are provided on the conveying baffle 111, and the auxiliary slide 311 is located on the outside of the main slide 211. A symmetrically arranged main slider 21 is fixedly installed on the slide 2, and the main slider 21 slides in the main slide 211. A secondary slider 31 is fixedly installed on the plate rack 3, and the secondary slider 31 slides in the secondary slide 311. The main slide 211 and the secondary slide 311 have the same depth, and lubricating oil is applied to both; and a secondary slide 312 connected to the auxiliary slide 311 is provided on the conveying baffle 111, so that when the secondary slider 31 slides to the position of the secondary slide 312, the distance between the slide 2 and the plate rack 3 is the largest, that is, the arc top of the secondary slide 312 is the high position of the plate rack 3 during movement.

[0047] Furthermore, the first elastic member 22 is fixedly installed between the slide 2 and the plate frame 3, and a telescopic rod is fixedly installed between the slide 2 and the plate frame 3, and the first elastic member 22 is arranged in a ring on the outside of the telescopic rod so that the plate frame 3 has a guiding and limiting effect when moving up and down; the first elastic member 22 is specifically a tension spring, and the first elastic member 22 keeps the distance between the slide 2 and the plate frame 3 to a minimum in the default state.

[0048] Furthermore, the middle of the plate frame 3 is hollowed out, and a strap 331 is set at the long side line of the rectangular plate frame 3. A symmetrically arranged support seat 32 is fixedly installed on the plate frame 3, and the plate shaft 33 is rotated circumferentially on the support seat 32. A pair of vertically arranged straps 331 are fixedly installed on the plate shaft 33, and this is a group, and the symmetrically arranged plate shafts 33 are two groups for placing plates coated with UV paint, and when the plates are placed on the vertically arranged straps 331, the edges of the plates still have a certain gap from the vertical straps 331 to facilitate the arc motion trajectory of the deflection of the straps 331. The panels are clamped and fixed, and when UV coating is applied to the panels, a distance of 2 mm is left from the edge of the panels so that the straps 331 do not touch the coating during clamping and affect drying. The panels (which may be lightweight wood panels, particle boards, or wood chip boards, etc.) are 5 to 10 cm thick. This is prior art and will not be described in detail here. The two vertically arranged straps 331 are of equal size. In the default state, the openings of the two sets of vertically arranged straps 331 are inclined at an angle of 45° facing upward. When the plate shaft 33 is rotated 45°, the two sets of vertically arranged straps 331 are completely arranged facing each other, that is, the openings are facing a point in the middle (such as Figure 7 As shown), the straps 331 are used to clamp and fix the four sides of the panel to fully display the panel.

[0049] In the above embodiment, the lifting drive source of the plate rack 3 can be an electric push rod, or a motor and a screw rod to drive the lifting, or any existing structure or existing component known to those skilled in the art.

[0050] In the above embodiment, the rotation driving source of the buttress 331 may be a motor.

[0051] The slide 2 is transferred by the conveyor belt 11 to the top of the conveyor belt 11, and then the plate coated with UV paint is placed on two sets of vertically arranged straps 331. At this time, the conveyor belt 11 works again to make the main slider 21 on the slide 2 and the auxiliary slider 31 on the plate rack 3 slide in the main slide 211 and the auxiliary slide 311 on the conveying baffle 111 respectively, and stops when the slide 2 reaches the bottom of the drying box 12. At this time, the auxiliary slider 31 reaches the top of the arc on the auxiliary sliding protrusion 312, and the plate rack 3 moves away from the slide 2, so that the first elastic member 22 is deformed, so that the two sets of straps 331 on the plate rack 3 lift the plate and suspend it in the air, so that the back of the plate The surface can be completely dried by the heat transfer in the drying box 12, which increases the heat transfer effect on the board and facilitates the rapid and uniform drying of the UV coating on the surface of the board; at the same time, with the two groups of straps 331 rotated 45 degrees towards each other, the two groups of straps 331 are arranged with their openings facing each other and clamp the board. At this time, the four side edges of the board and the surfaces of the two groups of vertically arranged straps 331 are in contact, so that under the action of line and surface contact, the board has the smallest contact surface and remains clamped and fixed, so that the board has an efficient and all-round effect when drying, thereby effectively solving the problem that the board coated with UV coating is unevenly heated and affects the curing.

[0052] As an embodiment further provided by the present invention, it also includes a screw rod 332 that is transmission-connected to the plate shaft 33 , and a screw protrusion 333 that is movable on the conveyor belt 11 is fixedly mounted on the screw rod 332 .

[0053] Specifically, such as Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the ends of the screw rod 332 and the plate shaft 33 maintain the screw transmission connection in the prior art, which is the prior art and will not be described in detail here; a wire protrusion 333 is fixedly installed on the end of the screw rod 332, and the wire protrusion 333 slides in the limiting path 334 opened on the conveying baffle 111, and the limiting path 334 is divided into a deep path 335 and a shallow path 336 according to the depth, and a hole is left between the limiting path 334 and the outside world for the movement of the screw rod 332, and the wire protrusion 333 will not be separated from the limiting path 334 during the sliding process (such as Figure 4 shown).

[0054] Furthermore, the cross section of the wire protrusion 333 is square, and the four edges of the wire protrusion 333 are rounded to ensure that the wire protrusion 333 does not rotate when sliding in the limit channel 334, and lubricating oil is applied in the limit channel 334 to facilitate the sliding of the wire protrusion 333.

[0055] The conveyor belt 11 is used to make the main slider 21 on the slide 2 and the auxiliary slider 31 on the plate frame 3 slide in the main slide 211 and the auxiliary slide 311 on the conveying baffle 111 respectively, so that the wire protrusion 333 is also affected by the conveyor belt 11 and slides in the limit path 334, and the wire protrusion 333 is respectively moved from the deep path 335 to the shallow path 336 and the shallow path 336 to the deep path 335, so that the screw rod 332 is kept close to / away from the plate shaft 33, thereby realizing the forward / reverse rotation of the plate shaft 33, so that the plate shaft 33 controls the vertically arranged strap 331 to rotate 45° to clamp and fix the plate, and when the plate is clamped and fixed by the strap 331, the auxiliary slider 31 reaches the top of the arc on the auxiliary slide 312, and the plate frame 3 moves away from the slide 2.

[0056] In the above embodiment, the driving source for the movement of the screw rod 332 can be an electric push rod, or a motor and a screw rod driven to move in translation, or any existing structure or existing component known to those skilled in the art.

[0057] As another embodiment further provided by the present invention, a mounting shaft 34 is horizontally movably provided on the plate frame 3 , and a pressure roller 36 is clamped and assembled on the mounting shaft 34 .

[0058] Specifically, such as Figure 3 and Figure 5 As shown, the middle of the plate frame 3 is hollowed out, and a pressure roller 36 is set at the short side line of the rectangular plate frame 3; a plurality of elastic metal plate protrusions are fixedly installed on the shaft 34, and the elastic metal plate protrusions are clamped in the holes opened on the inner ring of the pressure roller 36, and this clamping method is the existing technology and will not be described here. In the process of the pressure roller 36 approaching / moving away from the plate, the axis of the shaft 34 and the center line of the short side of the plate after placement remain parallel, and the diameter of the pressure roller 36 is specifically 8 cm.

[0059] By placing the panels coated with UV paint on two groups of vertically arranged straps 331, and when the panels are not placed regularly, that is, when the panels are twisted in the plane direction, the two pressure rollers 36 are moved closer to the panels to clamp and fix the panels, so that the panels placed on the straps 331 can be supported and positioned, that is, the panels are kept parallel to the conveyor belt 11 and the edges are aligned for transportation, ensuring that the panels are placed regularly when they arrive directly under the drying box 12, making it convenient for the two vertically arranged straps 331 to clamp and fix the panels, and when the panels are deflected, clamped and fixed by the straps 331, the two pressure rollers 36 are away from the panels, so that the panels are exposed to the maximum extent in the drying box 12 for drying; at the same time, the clamped and assembled pressure rollers 36 can be disassembled and cleaned, or replaced after being used for a long time.

[0060] As another embodiment further provided by the present invention, a symmetrically arranged sleeve shaft 341 is fixedly mounted on the mounting shaft 34 , a main sleeve ring 35 is movably sleeved on the sleeve shaft 341 , and a push rod 354 is provided on the main sleeve ring 35 to cooperate with the conveyor belt 11 .

[0061] Specifically, such as Figure 3 and Figure 5 As shown, a guide cavity 321 is provided on the support seat 32 for the sleeve shaft 341 to move repeatedly, a rack seat 322 is fixedly mounted on the support seat 32, a gear 342 is fixedly sleeved on the sleeve shaft 341, and the gear 342 and the rack seat 322 are meshed.

[0062] Furthermore, the sleeve shaft 341 rotates circumferentially on the main sleeve ring 35, and a torsion spring is provided at the rotating position so that the pressure roller 36 will deform the torsion spring when it is driven by the gear 342 to rotate and approach the plate; a slide column 351 is fixedly installed on the main sleeve ring 35, and the slide column 351 slides in the channel opened on the plate frame 3 to provide support force for the repeated movement of the pressure roller 36, and the end of the channel has a notch.

[0063] Furthermore, a push block 353 is fixedly mounted on the push rod member 354, and a second elastic member 352 and a telescopic rod are fixedly mounted between the push block 353 and the main sleeve 35, and the second elastic member 352 is arranged in a ring on the outside of the telescopic rod. The second elastic member 352 is specifically a spring. In the default state, the second elastic member 352 remains deformed (that is, the spring is in a compressed state) and minimizes the distance between the push block 353 and the main sleeve 35; a sliding block is fixedly mounted on the push rod member 354, and the sliding block slides in the sliding path opened on the conveying baffle 111, and the sliding path is the same as the limiting path 334, and the push rod member 354 is repeatedly moved by opening grooves of different depths, and acts on the main sleeve 35 to make the sleeve shaft 341 repeatedly move in the guide cavity 321 on the support seat 32.

[0064] The conveyor belt 11 is operated to make the main slider 21 on the slide 2 and the auxiliary slider 31 on the plate frame 3 slide in the main slide 211 and the auxiliary slide 311 on the conveying baffle 111 respectively, so that the sliding block on the push rod 354 also slides in the sliding path on the conveying baffle 111, and under the action of the shallow path in the sliding path, the push rod 354 pushes the main sleeve 35 to move closer to the plate, so that the sleeve shaft 341 pushes the pressure roller 36 to the plate, and the pressure roller 36 clamps and fixes the plate. At the same time, when the main sleeve 35 moves closer to the plate, the gear 342 on the sleeve shaft 341 and the rack seat 322 are engaged and drive the sleeve shaft 341 to move. When the plate is clamped, the roller 36 is rotated and squeezed, and the friction between the roller 36 and the plate is increased, thereby increasing the stability of the plate clamping. On the contrary, when the plate reaches the bottom of the drying box 12, the push rod 354 pulls the main sleeve 35 away from the plate under the action of the deeper channel in the sliding channel, so that the sleeve 341 moves the roller 36 away from the plate, thereby canceling the clamping and fixing of the plate by the roller 36, and facilitating the maximum exposure of the plate to the drying box 12 for drying.

[0065] In the above embodiment, the driving source for the pressing roller 36 can be a hydraulic rod, or a motor and a screw driven to drive the roller 36 to move horizontally, or any existing structure or component known to those skilled in the art.

[0066] As another embodiment further provided by the present invention, a locking rod 37 is movably provided on the plate frame 3, and a secondary collar 371 and a locking block 375 are fixedly installed on both sides of the locking rod 37;

[0067] A contact protrusion 337 is fixedly mounted on the plate shaft 33 , and the contact protrusion 337 abuts against the locking rod 37 to unlock the secondary collar 371 and the locking block 375 from locking the sleeve shaft 341 , and the pressure roller 36 moves repeatedly on the plate frame 3 under the action of elasticity.

[0068] Specifically, such as Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, the auxiliary ring 371 is fixedly mounted with a clamping block 372 which is symmetrically arranged in the upper and lower parts, and the guide cavity 321 is provided with a clamping channel 373 which is arranged in the upper and lower parts, and the clamping block 372 slides in the clamping channel 373, so that the auxiliary ring 371 corresponds to the repeated movement of the sleeve shaft 341 during the repeated movement; and a clamping hole 374 is provided at the end of the clamping channel 373, and when the auxiliary ring 371 unlocks the sleeve shaft 341, the clamping block 372 slides into the clamping hole 374.

[0069] Furthermore, when the locking rod 37 locks the sleeve shaft 341, the locking block 375 is inserted into the hole opened on the side wall of the push block 353; a fourth elastic member 376, specifically a spring, is fixedly mounted on the secondary collar 371, and the end of the fourth elastic member 376 abuts against the inner wall of the guide cavity 321. When the sleeve shaft 341 repeatedly moves in the guide cavity 321, the locking rod 37 in the locked state causes the end of the fourth elastic member 376 to slide in the guide cavity 321, and the fourth elastic member 376 is not deformed at this time; the length of the locking rod 37 corresponds to the length of the second elastic member 352 in the compressed state.

[0070] Furthermore, a contact frame 377 with a T-shaped cross section is fixedly mounted on the locking rod 37 , and a contact protrusion 337 is fixedly mounted on the side wall of the plate shaft 33 , and the contact protrusion 337 is abutted against one side of the contact frame 377 .

[0071] Furthermore, the butt plate 331 is provided with symmetrically arranged supply channels 338 , and the supply channels 338 are connected and matched with the notches on the channel where the sliding column 351 needs to slide.

[0072] Furthermore, since the drying box 12 uses a fan to circulate air during operation, and a small amount of dust remains on the plate, when the plate is dried by the drying box 12, the plate rack 3 continues to move so that the screw protrusion 333 continues to drive the screw rod 332 to rotate, and the vertically arranged straps 331 continue to rotate 45 degrees, so that the inclination angle of the openings of the two sets of vertically arranged straps 331 is 45 degrees downward (as shown in FIG. Figure 7 As shown), at this time, the plate falls onto the surface of the conveyor belt 11 due to the action of the strap 331, and at the same time, the strap 331 also secures the surface of the plate, so that the conveyor belt 11 continues to transport the plate frame 3 and the plate synchronously, and at this time the surface of the plate is below the low tangent of the side wall of the horizontal pressure roller 36.

[0073] When the conveyor belt 11 continues to work, the auxiliary slider 31 slides down from the arc top on the auxiliary sliding protrusion 312 and returns to the auxiliary slideway 311 again. At this time, as the first elastic member 22 recovers its deformation, the plate frame 3 is again close to the slide 2, and the two sets of vertically arranged straps 331 are close to the surface of the conveyor belt 11. At the same time, the plate frame 3 that continues to move makes the wire protrusion 333 continue to drive the screw rod 332 to rotate, and the vertically arranged straps 331 continue to rotate 45 degrees, so that the inclination angle of the openings of the two sets of vertically arranged straps 331 is 45 degrees downward, thereby achieving When the distance between the plate frame 3 and the slide 2 is kept at a minimum, the back of the plate contacts the surface of the conveyor belt 11 and falls onto the surface of the conveyor belt 11 with the action of the strap 331. At the same time, the strap 331 also secures the surface of the plate, so that the conveyor belt 11 continues to convey the plate frame 3 and the plate synchronously, and at the same time, the supply channel 338 on the strap 331 is connected to the notch on the channel required for the sliding of the slide column 351. At this time, the plate shaft 33 rotated 90 degrees makes the contact protrusion 337 contact one side of the contact frame 377, and causes the contact frame 377 to move away from the pressure roller 36, thereby The locking rod 37 is moved away from the second elastic member 352, and the secondary collar 371 is disengaged from the sleeve shaft 341, and the locking block 375 is disengaged from the hole on the push block 353. At this time, the blocking block 372 on the secondary collar 371 reaches the end of the blocking channel 373 and allows the blocking block 372 to enter the blocking hole 374. The fourth elastic member 376 is compressed and deformed, so that the locking rod 37 unlocks the sleeve shaft 341 and also unlocks and releases the compressed second elastic member 352. At this time, the second elastic member 352 suddenly recovers its deformation, so that the two pressure rollers 36 are subjected to the elastic potential equalization. It moves toward the middle of the plate, and the sliding column 351 on the main sleeve 35 enters into the supply channel 338 from the gap of the channel to provide the supporting force required for the translational sliding of the pressure roller 36. At the same time, the gear 342 and the rack seat 322 suddenly disengage, so that the torsion spring originally between the main sleeve 35 and the sleeve shaft 341 can quickly recover its deformation, and without the action of setting damping, the pressure roller 36 can quickly and repeatedly rotate forward and reverse alone, and without the action of setting damping on the second elastic member 352, the rotating pressure roller 36 can repeatedly move on the surface of the plate and gradually return to a standstill.

[0074] In the above embodiment, the driving source for the locking rod 37 can be a hydraulic rod, or a motor coupled with a screw to drive the translation, or any existing structure or component known to those skilled in the art.

[0075] As another embodiment further provided by the present invention, a plurality of cavities 361 are provided on the pressure roller 36 , and brush rods 363 for cooperating with the plate frame 3 are movably provided in the cavities 361 .

[0076] Specifically, such as Figure 5 and Figure 8As shown, multiple cavities 361 are arranged in a circular array on the side wall of the pressure roller 36, and symmetrically arranged scrapers 362 are fixedly installed at the ends of the cavities 361. The cross-section of the scrapers 362 is arc-shaped, and the ends of the scrapers 362 are facing the inside of the cavities 361.

[0077] Furthermore, soft bristles are fixedly installed on the brush rod 363, which is a prior art and will not be described in detail here. A plurality of third elastic members 364 are fixedly installed between the brush rod 363 and the cavity 361. The third elastic member 364 is specifically a tension spring, and the third elastic member 364 causes the brush rod 363 to be accommodated in the cavity 361 in the default state, thereby preventing the brush rod 363 from extending from the cavity 361 when the pressure roller 36 is driven to rotate by the gear 342; symmetrically arranged blocks are fixedly installed on the brush rod 363, and the blocks are caused to slide in the holes opened in the cavity 361 to provide guide limits for the brush rod 363 when it moves.

[0078] The locking rod 37 unlocks the sleeve shaft 341 and also unlocks and releases the compressed second elastic member 352. At this time, the second elastic member 352 suddenly recovers its deformation, so that the two pressure rollers 36 are able to translate and move closer to the middle of the plate due to the elastic potential of the shape. At the same time, the gear 342 and the rack seat 322 suddenly disengage, so that the torsion spring originally between the main sleeve ring 35 and the sleeve shaft 341 quickly recovers its deformation, and without the action of setting damping, the pressure roller 36 is able to quickly and repeatedly perform forward and reverse rotation alone, and without the action of setting damping on the second elastic member 352, the rotating pressure roller 36 is able to repeatedly perform forward and reverse rotation repeatedly. It moves on the surface of the plate, so that the centrifugal force generated by the rapid rotation of the pressure roller 36 causes the brush rod 363 to extend out of the cavity 361, and accompanied by the deformation of the third elastic member 364, the bristles on the brush rod 363 contact the completely preliminarily dried surface of the plate, and under the action of the second elastic member 352, the pressure roller 36 repeatedly moves on the surface of the plate, so that the bristles on the brush rod 363 wipe the surface of the plate under the synchronous action of the repeated movement and rotation of the pressure roller 36, thereby wiping the dust remaining on the surface of the plate, reducing the dust existing after the preliminary drying of the plate and affecting the subsequent processing.

[0079] Secondly, when the pressure roller 36 stops rotating, the brush rod 363 returns to the cavity 361 under the action of the third elastic member 364 restoring the deformation, and at the same time cooperates with the scraper 362 to scrape off the dust attached to the bristles and store it in the cavity 361, so that the pressure roller 36 can be used for a long time to temporarily store dust.

[0080] As another embodiment further provided by the present invention, a telescopic box 4 is movably mounted on the drying box 12 , and the plate frame 3 abuts against the telescopic box 4 to extend the telescopic box 4 .

[0081] Specifically, such as Figure 1 、 Figure 2 and Figure 9As shown, the telescopic box 4 is similar to a telescopic rod, an old-fashioned broadcast hand-pulled antenna, etc., and a pulley is provided between every two gradually shrinking telescopic boxes 4, and is used to facilitate the expansion of the telescopic box 4, and a tension spring is provided at the connection position. When the telescopic box 4 is expanded, the tension spring is deformed, and the tension spring has damping in the process of restoring the deformation, so that the telescopic box 4 keeps moving slowly when stored, and the telescopic box 4 as a whole and its components are all existing technologies and will not be described here.

[0082] Furthermore, when the plate frame 3 is moved by the conveyor belt 11, the support seat 32 on the plate frame 3 abuts against the smallest inner wall of the telescopic box 4, and the main slide 211 and the auxiliary slide 311 on the conveying baffle 111 near the conveying tail of the conveyor belt 11 are bent toward the surface of the conveyor belt 11 and restored to a horizontal position (as shown in FIG. Figure 9 (shown by the dashed line).

[0083] When the conveyor belt 11 continues to work, the auxiliary slider 31 slides down from the top of the arc on the auxiliary slide 312 and returns to the auxiliary slide 311 again. At this time, the first elastic member 22 recovers its deformation to make the plate rack 3 close to the slide 2 again. At the same time, the support seat 32 on the plate rack 3 pushes the smallest box in the telescopic box 4 to unfold, and all the boxes in the telescopic box 4 are unfolded in turn, so that the heat in the drying box 12 diffuses into the unfolded telescopic box 4, so that the diffused residual heat acts on the surface of the plate again, and uses the residual heat to dry the UV coating for a second time, which greatly reduces the need to assemble multiple drying boxes 12.

[0084] Secondly, when the main slider 21 and the auxiliary slider 31 reach the downward bending portion of the main slide 211 and the auxiliary slide 311 , the support seat 32 loses contact with the telescopic box 4 , making it easier for the plate frame 3 to detach from the telescopic box 4 .

[0085] As another embodiment further provided by the present invention, symmetrically arranged shift plates 43 are provided in the telescopic box 4 , and a pull rope 432 is provided between the shift plates 43 and the drying box 12 . When the telescopic box 4 is in the extended state, the shift plates 43 abut against the pressure roller 36 .

[0086] Specifically, such as Figure 1 、 Figure 3 、 Figure 5 、 Figure 9 and Figure 10 As shown, a bracket is fixedly installed in the drying box 12, one end of the pull rope 432 is fixedly installed on the bracket, and the other end is fixedly installed on the dial plate 43; and a dial frame 42 is fixedly installed on the inner wall of the smallest box in the telescopic box 4, and a rod is fixedly installed on the dial frame 42, and a pulley member 433 is movably provided on the rod, and the pull rope 432 and the pulley member 433 are assembled and used, which is existing technology and will not be described in detail here.

[0087] Furthermore, the shift rack 42 is symmetrically arranged in the telescopic box 4, and the shift rack 42 and the pressure roller 36 that is not fully released are in the same side position, the shift rack 42 is fixedly mounted with a symmetrically arranged sliding rod 421, and a stopper is fixedly mounted at the end of the sliding rod 421, the shift plate 43 slides on the sliding rod 421 without disengaging, and a symmetrically arranged fifth elastic member 431 is fixedly mounted between the shift plate 43 and the shift rack 42, and the fifth elastic member 431 is annularly arranged on the outside of the sliding rod 421, and the fifth elastic member 431 is specifically a spring, and the fifth elastic member 431 keeps the shift plate 43 away from the shift rack 42 in the default state.

[0088] The smallest box in the telescopic box 4 is pushed to unfold through the support seat 32 on the plate frame 3, and all the boxes in the telescopic box 4 are unfolded in turn, so that the smallest box in the telescopic box 4 causes the pull rope 432 to pull the dial plate 43 closer to the dial frame 42 through the pulley 433 during the process of moving away, and at the same time, the fifth elastic member 431 is deformed, so that the dial plate 43 pushes the pressure roller 36 that has returned to rest to the position of the shorter edge line of the plate frame 3, and at the same time, the second elastic member 352 is compressed and deformed again, until when the plate frame 3 slides out of the telescopic box 4, the second elastic member 352 is completely compressed and returns to the default state, which facilitates the pressure roller 36 to perform the extrusion and clamping work of the next plate and the wiping work of the plate surface.

[0089] Secondly, with the continued movement of the plate rack 3, the wire protrusion 333 is affected by the limit 334 of different depths, driving the screw rod 332 to rotate in the opposite direction, and the vertically arranged straps 331 are rotated in the opposite direction by 90 degrees, so that the inclination angles of the openings of the two sets of vertically arranged straps 331 return to facing upward at 45 degrees (as shown in FIG. Figure 7 As shown), the two sets of vertically arranged straps 331 are used to scoop up the panels again and place them in an upward position. At the same time, the sliding columns 351 on the main sleeve 35 are prevented from interfering with the deflection of the straps 331, making it convenient to remove the panels from the straps 331 when the panel rack 3 is moved out of the telescopic box 4.

[0090] In the above embodiment, the driving source for the movement of the dial plate 43 can be an electric push rod, or a motor and a screw driven to drive the translation, or any existing structure or existing component known to those skilled in the art.

[0091] As another embodiment further provided by the present invention, a cover door 41 is hingedly provided on the telescopic box 4 , and the locking rod 37 abuts against the cover door 41 and is used to lock the sleeve shaft 341 .

[0092] Specifically, such as Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 、 Figure 9 and Figure 10As shown, a torsion spring is provided at the hinged position of the cover door 41, and the torsion spring enables the cover door 41 to close the outlet of the telescopic box 4 in a default state.

[0093] When the main slider 21 and the auxiliary slider 31 reach the downward bending part of the main slide 211 and the auxiliary slide 311, the support seat 32 loses the contact with the telescopic box 4. At this time, the plate frame 3 is detached from the telescopic box 4, and the horizontal end of the "T"-shaped contact frame 377 contacts the cover door 41, so that the cover door 41 opens the outlet of the telescopic box 4, so that the plate placed on the strap 331 after 90° deflection in the opposite direction slides out of the telescopic box 4, and when the contact frame 377 contacts the cover door 41, the contact frame 377 slides in the opposite direction, and the auxiliary ring 371 on the locking rod 37 is again sleeved on the sleeve shaft 341 that returns to the extrusion and clamping position, and the locking block 375 is also inserted into the hole on the push block 353, so that the second elastic member 352 is compressed and stored again, and the gear 342 and the rack seat 322 are meshed again, and the pressure roller 36 can also perform the extrusion and clamping work of the plate again.

[0094] In the above embodiment, the deflection driving source of the cover door 41 may be a motor.

[0095] Working principle: The slide 2 is transferred by the conveyor belt 11 to the top of the conveyor belt 11, and then the plate coated with UV paint is placed on two groups of vertically arranged straps 331. At this time, the conveyor belt 11 works again to make the main slider 21 on the slide 2 and the auxiliary slider 31 on the plate rack 3 slide in the main slide 211 and the auxiliary slide 311 on the conveying baffle 111 respectively, and stops when the slide 2 reaches the bottom of the drying box 12. At this time, the auxiliary slider 31 reaches the top of the arc on the auxiliary slide 312, and the plate rack 3 moves away from the slide 2, so that the first elastic member 22 is deformed, and the two groups of straps 331 on the plate rack 3 lift the plate and suspend it in the air, so that the back of the plate can be completely dried by the heat transfer in the drying box 12, thereby increasing the heat transfer effect on the plate and facilitating the rapid and even drying of the UV paint on the surface of the plate.

[0096] Secondly, the conveyor belt 11 works to make the main slider 21 on the slide 2 and the auxiliary slider 31 on the plate frame 3 slide in the main slide 211 and the auxiliary slide 311 on the conveying baffle 111 respectively, so that the sliding block on the push rod 354 also slides in the sliding path on the conveying baffle 111, and under the action of the shallow path in the sliding path, the push rod 354 pushes the main sleeve 35 to move closer to the plate, so that the sleeve shaft 341 pushes the pressure roller 36 to the plate, realizing the clamping and fixing of the plate by the pressure roller 36. At the same time, when the main sleeve 35 moves closer to the plate, the gear 342 on the sleeve shaft 341 and the rack seat 322 are engaged. And drive the sleeve shaft 341 to rotate, so that the sleeve shaft 341 drives the pressure roller 36 to rotate under the action of the mounting shaft 34, so that the pressure roller 36 also rotates and squeezes in the process of approaching the plate for clamping, thereby additionally increasing the friction force of the pressure roller 36 on the plate and increasing the stability of the plate clamping; conversely, when the plate reaches the bottom of the drying box 12, under the action of the deeper channel in the sliding channel, the push rod 354 pulls the main sleeve ring 35 away from the plate, so that the sleeve shaft 341 moves the pressure roller 36 away from the plate, realizing the cancellation of the clamping and fixation of the plate by the pressure roller 36, and facilitating the maximum exposure of the plate to the drying box 12 for drying.

[0097] The cam 331 of the second conveyor belt 11 is fixed on the upper surface of the workbench 33 and the lower surface of the workbench 33 is fixed on the upper surface of the workbench 33 so that the workbench 33 is fixed on the upper surface of the workbench 33.

[0098] When the cam 331 is in the downward position, the first and second plates 331 are in the downward position, and the second and second plates 331 are in the downward position, so that the cam 331 is ... and the second and second plates 331 are in the downward position, and the second and second plates 331 are in the downward position, and the second and second plates 331 are in the downward position, and the second and second plates 331 are in the downward position, and the second and second plates 331 are in the downward position, and the second and second plates 331 are in the downward position, and the second and second plates 331 are in the downward position, and the second and second plates 331 are in the downward position, and the second and second plates 331 are in the downward position, and the second and second plates 331 are in The cam 375 is moved away from the second spring 352 and the second spring 376 is moved away from the second spring 353. At this time, the locking block 372 on the secondary collar 371 reaches the end of the channel 373 and enters the locking hole 377. 4, and accompanied by the compression deformation of the fourth elastic member 376, the locking rod 37 unlocks the sleeve shaft 341, and also unlocks and releases the compressed second elastic member 352. At this time, the second elastic member 352 suddenly recovers its deformation, so that the two pressure rollers 36 can move horizontally and move closer to the middle of the plate due to the elastic potential, and the sliding column 351 on the main sleeve ring 35 enters the supply channel 338 from the notch of the channel to provide the support force required for the translation and sliding of the pressure roller 36. At the same time, the gear 342 and the rack seat 322 suddenly disengage, so that the torsion spring originally between the main sleeve ring 35 and the sleeve shaft 341 quickly recovers its deformation, and without the action of setting damping, the pressure roller 36 can quickly and repeatedly perform forward and reverse rotations alone. And under the action of the second elastic member 352, which is also not provided with damping, the rotating pressure roller 36 repeatedly moves on the surface of the plate and gradually returns to stillness. At the same time, the centrifugal force generated by the rapid rotation of the pressure roller 36 causes the brush rod 363 to extend out of the cavity 361, and accompanied by the deformation of the third elastic member 364, the bristles on the brush rod 363 contact the completely preliminarily dried surface of the plate, and under the action of the second elastic member 352, the pressure roller 36 repeatedly moves on the surface of the plate, so that the bristles on the brush rod 363 wipe the surface of the plate under the synchronous action of the repeated movement and self-rotation of the pressure roller 36, thereby wiping the dust remaining on the surface of the plate, reducing the dust existing after the initial drying of the plate and affecting the subsequent processing.

[0099] Furthermore, as the support base 32 on the plate rack 3 pushes the smallest box in the telescopic box 4 to unfold, and all the boxes in the telescopic box 4 are unfolded in turn, the heat in the drying box 12 diffuses into the unfolded telescopic box 4, so that the diffused residual heat acts on the surface of the plate again, and the residual heat is used to dry the UV coating for a second time, which greatly reduces the need to assemble multiple drying boxes 12.

[0100] Finally, the support seat 32 on the plate frame 3 pushes the smallest box in the telescopic box 4 to unfold, and unfolds all the boxes in the telescopic box 4 in turn, so that the smallest box in the telescopic box 4 causes the pull rope 432 to pull the dial plate 43 close to the dial frame 42 through the pulley member 433 during the process of moving away, and at the same time, the fifth elastic member 431 is deformed, so that the dial plate 43 pushes the pressure roller 36 that has returned to rest to the position of the shorter edge line of the plate frame 3, and at the same time, the second elastic member 352 is compressed and deformed again until when the plate frame 3 slides out of the telescopic box 4, the second elastic member 352 is completely compressed and returns to the default state, making it convenient for the pressure roller 36 to perform the squeezing and clamping work of the next plate and the wiping work of the plate surface, and the main slider 21 and the auxiliary slider 31 reach the downward bending part of the main slide 211 and the auxiliary slide 311 When the support seat 32 loses its contact with the telescopic box 4, the plate frame 3 is now detached from the telescopic box 4, and the horizontal end of the "T"-shaped contact frame 377 contacts the cover door 41, so that the cover door 41 opens the outlet of the telescopic box 4, so that the plate placed on the strap 331 after being deflected 90 degrees in the opposite direction slides out of the telescopic box 4, and when the contact frame 377 contacts the cover door 41, the contact frame 377 slides in the opposite direction, and the secondary ring 371 on the locking rod 37 is again sleeved on the sleeve shaft 341 that returns to the extrusion and clamping position, and the locking block 375 is also inserted into the hole on the push block 353, so that the second elastic member 352 is compressed and stored again, and the gear 342 and the rack seat 322 are meshed again, and the pressure roller 36 can also extrude and clamp the plate again.

[0101] A method for omnidirectional UV drying of thermal transfer films, comprising the above-mentioned omnidirectional UV drying machine for thermal transfer films, and the steps are as follows:

[0102] S1. Prepare several panels to be dried and coated with UV coating;

[0103] S2, placing the plate to be dried on the board 331 for transportation preparation;

[0104] S3, the plate 331 is used to reach the bottom of the drying box 12 from the conveyor belt 11, and the auxiliary slider 31 on the plate rack 3 is slidably matched with the arc top of the auxiliary sliding protrusion 312 to lift the plate into the air, and at the same time, the two sets of plates 331 rotated 45 degrees in opposite directions are matched so that the openings of the two sets of plates 331 are arranged facing each other and the plate is clamped and fixed. At this time, the four side edges of the plate and the surfaces of the two sets of vertically arranged plates 331 are in contact, so that under the action of line and surface contact, the plate has a minimum contact surface and remains clamped and fixed, so that the plate has an efficient and all-round effect when drying, and then the UV paint applied on the surface of the plate is irradiated by multiple UV lamps to achieve full heat curing of the plate;

[0105] S4, when the conveyor belt 11 continues to work, the auxiliary slide 31 slides down from the arc top on the auxiliary sliding protrusion 312 and returns to the auxiliary slide 311 again. At this time, the first elastic member 22 recovers its deformation to make the plate rack 3 move closer to the slide 2 again. At the same time, the support seat 32 on the plate rack 3 pushes the smallest box in the telescopic box 4 to expand, and then all the boxes in the telescopic box 4 are expanded in turn, so that the heat in the drying box 12 is diffused into the expanded telescopic box 4, and the residual heat is used to heat cure the plate.

[0106] S5. The sleeve shaft 341 is unlocked by the locking rod 37, and the compressed second elastic member 352 is also unlocked and released. At this time, the second elastic member 352 suddenly recovers its deformation, so that the two pressure rollers 36 are able to translate and move closer to the middle of the plate due to the elastic potential of the shape. At the same time, the gear 342 and the rack seat 322 suddenly disengage, so that the torsion spring originally between the main sleeve ring 35 and the sleeve shaft 341 quickly recovers its deformation, and without setting the damping, the pressure roller 36 can quickly and repeatedly perform the forward and reverse rotation state alone, and no damping is set on the second elastic member 352. Under the action of the rubber, the rotating pressure roller 36 repeatedly moves on the surface of the plate, so that the centrifugal force generated by the rapid rotation of the pressure roller 36 causes the brush rod 363 to extend out of the cavity 361, and accompanied by the deformation of the third elastic member 364, the bristles on the brush rod 363 contact the completely preliminarily dried surface of the plate, and under the action of the second elastic member 352, the pressure roller 36 repeatedly moves on the surface of the plate, so that the bristles on the brush rod 363 wipe the surface of the plate under the synchronous action of the repeated movement and rotation of the pressure roller 36, thereby wiping the dust remaining on the surface of the plate;

[0107] S6. Finally, the cover door 41 is opened to allow the plate to be sent out via the conveyor belt 11.

[0108] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
