Description

Technical Field

[0001] The invention relates to the technical field of curing furnaces, and in particular to an intelligent temperature-controlled reflective film curing furnace. Background Art

[0002] Reflective film curing furnace is a kind of equipment specially used for curing the surface coating of reflective film or making its material undergo curing reaction. Reflective film curing furnace heats the air or directly heats the reflective film, so that the coating, glue and other substances on the surface of the reflective film react chemically at a certain temperature, thereby forming a solid coating or curing the material into shape. Its heating methods usually include electric heating, gas heating, infrared heating, etc. Reflective film curing furnace is mainly used in the manufacturing and processing of reflective materials, such as traffic signs, road safety facilities, etc. Through curing treatment, the wear resistance, corrosion resistance and reflective performance of the reflective film can be improved, thereby extending its service life and enhancing safety.

[0003] The Chinese patent with announcement number CN219160943U discloses a tunnel curing furnace. The solution of this patent mainly solves the problem of difficulty in replacing the heating wire. It mainly removes the limit by pulling the pull block to make the plug rod leave the socket, and then pulls the long block outward to finally remove the heating wire. However, this manual method is relatively cumbersome, and there are too many heating wires in a curing furnace, and manual replacement is relatively troublesome and time-consuming. In addition, during the curing process, since the object to be cured is a reflective film, due to temperature reasons, the luminous film is prone to shrinkage, which will affect the final winding effect.

[0063] like Figure 1-2As shown, the present invention provides a technical solution: an intelligent temperature-controlled reflective film curing furnace, comprising a base 1, a furnace body 2, an adjustment component 5 and a drive component 6, the furnace body 2 is installed on the base 1, and a control console 11 with a PLC controller is installed on one side wall of the furnace body 2 by screws, an inlet and an outlet are respectively opened on the left and right sides of the furnace body 2, a cavity connected to the furnace body 2 is opened in the base 1, and an inclined guide plate 12 is installed between the base 1 and the inner wall of the furnace body 2 by screws, and the guide plate 12 is above the furnace body 2. A vertically arranged baffle is installed between the inner walls of the furnace body 2 by screws, and a plurality of heating components 3 are equidistantly arranged inside the furnace body 2 on one side of the baffle for heating and curing the reflective film, and an inspection component 4 capable of adjusting the position along the length direction of the furnace body 2 is arranged on the outer side of the furnace body 2, and the inspection component 4 can be individually matched and adjusted with the heating component 3, and a roller brush 21 is rotatably arranged between the inner walls of the furnace body 2 on the other side of the baffle, and a rotating motor 1 for driving the roller brush 21 is installed on the outer wall of the furnace body 2 by screws on one side of the roller brush 21.

[0064] An adjusting component 5 is arranged between two adjacent heating components 3. The adjusting component 5 is arranged between the furnace body 2 and the inner wall of the cavity, and is used for self-adjusting and restoring the shrinkage reaction of the reflective film during the heating and curing process. A driving component 6 is also arranged between the maintenance component 4 and the adjusting component 5. The driving component 6 is installed on the outside of the furnace body 2, and the driving component 6 is used to control the maintenance position adjustment of the maintenance component 4 and the driving of the adjusting component 5 respectively.

[0065] like Figure 3-5 As shown, the heating assembly 3 includes a fixing box 31, a mounting plate 32 and a heating element 322;

[0066] A mounting hole 1 is provided on the furnace body 2 and is arranged along the width direction of the furnace body 2. A fixing box 31 is fixed between the inner walls of the mounting hole 1 by screws. The bottom and one side end wall of the fixing box 31 are open, and inner grooves are provided on the opposite inner walls on both sides of the fixing box 31 along the length direction thereof.

[0067] The mounting plate 32 is provided with a second mounting hole that is set through, and a heating element 322 is detachably installed between the inner walls of the second mounting hole, wherein the heating element 322 is an electric heating wire or an infrared lamp (an electric heating wire is used in this embodiment), and guide bars that are connected to the mounting plate 32 are provided on both side walls of the mounting plate 32, and the guide bars slide and adjust along the inner groove, and an adsorption member 321 is installed on the bottom surface of the mounting plate 32 by screws, and the adsorption member 321 is a magnet sheet, and a suction strip matching the magnet sheet is embedded on the outer wall of the furnace body 2, and two tooth grooves symmetrically distributed on both sides of the second mounting hole are provided on the top surface of the mounting plate 32.

[0068] During the sliding process of the mounting plate 32 along the fixing box 31, one end of the mounting plate 32 never leaves the fixing box 31, and when the mounting plate 32 is Figure 5 The state shown is completely moved into the fixing box 31 until Figure 3 In the state shown, the suction strip is in contact with the magnet sheet and connected together by suction, and the heating element 322 is in a conductive state.

[0069] It should be noted that a power socket (not shown in the figure) is embedded on the inner wall of the end of the fixed box 31 that contacts the mounting plate 32, and a contact head (not shown in the figure) is embedded on the end wall of the mounting plate 32 that contacts the inner wall of the fixed box 31, that is, when the end of the mounting plate 32 contacts the inner wall of the fixed box 31, the power socket contacts the contact head and realizes the conduction of the circuit, thereby realizing the heating work of the heating element 322.

[0070] In addition, the output power upper limit of the power socket can be changed through the control console 11, so as to adjust the temperature of the heating element 322.

[0071] The maintenance assembly 4 includes a moving seat 41, a lifting seat 42 and an adjusting gear 43;

[0072] A guide groove 13 is provided on the outer wall of the furnace body 2 along its length direction. The movable seat 41 is in a "T"-shaped structure, and one end thereof slides between the inner walls of the guide groove 13. A screw hole is provided on the other end of the movable seat 41. A lifting motor is installed on the top surface of the movable seat 41 by screws, and a lifting seat 42 is installed on the end of the output shaft of the lifting motor by screws. The lifting seat 42 is in a "U"-shaped structure. A rotating motor 2 is installed on one side wall of the lifting seat 42 by screws. The output shaft of the rotating motor 2 penetrates and rotates between the side walls of the lifting seat 42. Two symmetrically arranged adjusting gears 43 are installed on the output shaft of the rotating motor 2 in a key connection manner. The position of the adjusting gear 43 remains unchanged, and the two adjusting gears 43 can respectively engage and match with the two rows of guide grooves on the same mounting plate 32.

[0073] It should be further explained that the position of the moving seat 41 is controlled by a screw transmission driving mode. After the moving seat 41 is adjusted to the maintenance position, the lifting motor is started, and its output shaft extends downward to the maximum distance, thereby driving the lifting seat 42 to adjust the position downward. At this time, one of the teeth of the adjusting gear 43 just contacts the end of the mounting plate 32, and another tooth adjacent to the tooth on the adjusting gear 43 also just meshes with the tooth groove on the mounting plate 32 (such as Figure 4Then, by starting the rotating motor 2, its output shaft drives the two adjusting gears 43 to rotate, so that the mounting plate 32 is driven by the adjusting gears 43 to move toward the outside of the fixing box 31, and the heating element 322 can be stopped when it moves out of the furnace body 2, and then the heating element 322 is replaced. After the replacement is completed, the adjusting gear 43 is controlled to rotate in the opposite direction, so that the mounting plate 32 is moved back into the fixing box 31, and the installation is completed when the mounting plate 32 contacts the inner wall of the fixing box 31. At this time, the heating element 322 also enters the working state under the matching of the contact head and the power socket.

[0074] like Figure 6-8 As shown, the adjustment assembly 5 includes an adjustment seat 51, an adjustment member 52, a clamping seat 53, an adjustment arm 54, a rotating handle 55 and a rotating arm;

[0075] The adjustment seat 51 is slidably adjusted along the inner walls of the cavity, a T-shaped frame 511 is installed in the middle of the top surface of the adjustment seat 51 by screws, two through holes are opened on the adjustment seat 51, the two through holes are symmetrically distributed about the T-shaped frame 511, and the bottom opening of the adjustment seat 51 is set, and an adjustment member 52 with a "⊥"-shaped structure is slidably set between the inner walls of the adjustment seat 51, the adjustment member 52 also slides between the inner walls of the through hole, and a "T"-shaped connecting bolt 522 is welded in the middle of the bottom wall of the adjustment member 52, and a reset tension spring 512 is installed between the connecting bolts 522 on both sides.

[0076] A key shaft 532 is installed on the side wall of the clamp seat 53 facing the inner wall of the furnace body 2 by screws, and a limiting sleeve 57 is slidably arranged on the inner wall of the furnace body 2 along the length direction of the furnace body 2 (that is, a sliding groove matching the limiting sleeve 57 is opened on the inner wall of the furnace body 2, not shown in the figure), one end of the key shaft 532 always slides between the inner walls of the limiting sleeve 57, the limiting sleeve 57 has a "convex" structure, and a connecting seat 531 is installed in the middle of the bottom wall of the clamp seat 53 by screws.

[0077] Two parallel and synchronous adjusting arms 54 are rotatably connected via an axis at the two opposite ends of the T-shaped frame 511. A connecting shaft 3 is passed through the inner walls of the connecting seat 531 and fixed thereto. A fixing hole 1 is provided along the length direction of the adjusting arm 54 at one end. The connecting shaft 3 slides between the inner walls of the fixing hole 1. Rotating blocks 521 are rotatably connected via an axis on both side walls of the adjusting member 52. A fixing hole 2 is provided along the length direction of the adjusting arm 54 at the other end. The rotating block 521 moves between the inner walls of the fixing hole 2.

[0078] It should be noted that in order not to affect the movement adjustment of the top of the adjustment arm 54, a bottom groove (not shown in the figure) adapted to the adjustment arm 54 is opened on the bottom wall of the clamp seat 53 to facilitate the top adjustment movement of the adjustment arm 54.

[0079] One end of the swing arm 58 is connected and rotated on the inner wall of the cavity through an axis, and a fixing hole three is opened on the other end of the swing arm 58 along its length direction, and a fixing hole four is also opened at the middle position of the swing arm 58, and the fixing hole four is also set along the length direction of the swing arm 58, and the limiting sleeve 57 slides between the inner walls of the fixing hole three.

[0080] One end of the rotating handle 55 is connected and rotated on one side of the inner wall of the furnace body 2 through an axis, and a T-shaped shaft is rotatably set on the other end of the rotating handle 55, and the other end of the T-shaped shaft slides between the inner walls of the fixing hole 4. The rotating handles 55 on both sides are connected to a bevel gear 1 551 that rotates synchronously with the outer wall of the furnace body 2 on one side of the rotation center of the rotating handle 55, and a bevel gear 2 56 is meshed with one side of the bevel gear 1 551, and the bevel gears 2 56 on both sides of the furnace body 2 are set in opposite directions.

[0081] A protective shell is installed on the top surface of the clamp seat 53 by screws. Two electric push rods are installed in the protective shell. The ends of the electric push rods are connected to a pressing piece 533. The edge of the reflective film is pressed between the pressing piece 533 and the clamp seat 53.

[0082] The rotation center of the rotating handle 55 and the swing center of the swing arm 58 are located on the same vertical line, and both fall on the perpendicular midline of the center connection line of two adjacent heating components 3 .

[0083] It should be further explained that the rotation of the bevel gear 1 551 synchronously drives the circular motion of the rotating handle 55, so that the T-shaped shaft continuously moves between the inner walls of the fixing hole 4, thereby synchronously controlling the reciprocating swing of the swing arm 58, thereby driving the clamping seat 53 to reciprocate between the two adjacent heating components 3, so as to Figure 2 As shown in the figure, when the clamp seat 53 moves to the adjacent and left side heating component 3, the electric push rod starts to control the pressing plate 533 to press the edge of the reflective film. When the clamp seat 53 moves to the adjacent and right side heating component 3, the electric push rod resets and stops, and the pressing plate 533 moves up and away from the reflective film. When the clamp seat 53 moves back to the left side heating component 3 again, the edge of the reflective film is clamped and fixed again, thereby coordinating the conveying work of the reflective film.

[0084] Furthermore, if Figure 7 As shown in FIG. 1 , if the reflective film shrinks during the heating and curing process, the clamping seats 53 on both sides will be driven to move toward the middle side, and at this time, the key shaft 532 will move outward along the inner wall of the limiting shaft sleeve 57 for adjustment, but the key shaft 532 will not separate from the limiting shaft sleeve 57, and the top of the adjustment arm 54 will also move synchronously with the movement of the clamping seat 53. Figure 7 The middle side moves, and at the same time, the bottom of the adjustment arm 54 moves to Figure 7The adjusting members 52 on both sides also slide opposite to each other as the adjusting arms 54 on both sides swing, thereby applying a force to the reset spring 512. Under the self-restoring action of the reset spring 512, the adjusting members 52 on both sides are driven to slide relative to each other and reset, thereby enabling the clamping seat 53 originally driven by the reflective film to be reset, thereby restoring the tension of the shrunk reflective film part, thereby achieving the problem of the shrinkage of the self-adjusting reflective film during the heating and curing process.

[0085] like Fig. 9 As shown, the driving assembly 6 includes an L bracket 61, a driving gear 62, an electric cylinder 63, an output shaft 1 64 and an output shaft 2 65;

[0086] Two groups of shaft seats 16 are installed on the opposite side walls of the furnace body 2 by screws, each group includes two shaft seats 16, and two shaft seats 15 are installed on the side wall of the furnace body 2 on one side by screws. The shaft seat 15 is located between the two shaft seats 16 at the same height, and an output shaft 164 (the output shaft 164 is a threaded rod) is rotatably arranged between one of the shaft seats 16 and the shaft seat 15 located at the top. The output shaft 164 passes through the movable seat 41 and is arranged with it through a threaded transmission, and the other shaft seat 15 located at the top is rotatably arranged between the two shaft seats 16 and the shaft seat 15. A connecting shaft 641 is rotatably arranged between the shaft seat 2 16 and the shaft seat 1 15, and a synchronous member 151 is passed through the inner wall of the upper shaft seat 15 and is in rotational contact with the synchronous member 151, and the synchronous member 151 is an electromagnet with an axial structure, and the synchronous member 151 and the control console 11 are connected and controlled by a wire, and the synchronous member 151 is connected to the output shaft 64 as a whole, one end of the connecting shaft 641 rotates between the inner walls of the synchronous member 151, and the connecting shaft 641 and the synchronous member 151 can be connected as a whole by the suction force of the electromagnet.

[0087] An output shaft 2 65 is rotatably arranged between one of the shaft seats 2 16 and the shaft seat 1 15 located below, and a connecting shaft 2 651 is rotatably arranged between the other shaft seat 2 16 and the shaft seat 1 15 located below. A synchronous member 151 is also passed through the inner walls of the shaft seat 15 below and is in rotational contact with the synchronous member 151. The synchronous member 151 is connected to the output shaft 2 65 as a whole, and one end of the connecting shaft 2 651 also rotates between the inner walls of the synchronous member 151, and the connecting shaft 2 651 and the synchronous member 151 can also be connected as a whole through the suction force of the electromagnet.

[0088] Among them, the synchronous member 151 and the shaft seat 15 can also be connected as a whole through suction, and a synchronous belt 1 is installed between one end of the connecting shaft 2 651 on both sides of the base 1 through a synchronous wheel 1.

[0089] A driven gear 1 642 is also installed on the connecting shaft 1 641 and rotates synchronously therewith, and a driven gear 2 652 is installed on the connecting shaft 2 651 and rotates synchronously therewith. The specifications and dimensions of the driven gear 1 642 and the driven gear 2 652 are set to be the same, and a synchronous belt 2 is also connected between the connecting shaft 1 641 and the connecting shaft 2 651 through a synchronous wheel 2. The two synchronous wheels 2 are fixedly installed on the connecting shaft 1 641 and the connecting shaft 2 651 respectively.

[0090] An electric cylinder 63 is also installed on the base 1, and an L bracket 61 is installed on the end of the output shaft of the electric cylinder 63 by screws, and a rotating motor three is installed on the L bracket 61 by screws, and a driving gear 62 is installed on the end of the output shaft of the rotating motor three. The driving gear 62 can mesh with the driven gear 1 642 and the driven gear 2 652 for transmission, which is equivalent to the driven gear 1 642 and the driven gear 2 652 being meshed on both sides of the driving gear 62, respectively. However, now the positions of the driven gear 1 642 and the driven gear 2 652 are only set above and below the driving gear 62, but the driven gear 1 642 and the driven gear 2 652 are always kept in a state of being able to mesh with the driving gear 62 through the action of the synchronous belt 2, that is, when either the driven gear 1 642 or the driven gear 2 652 rotates with the driving gear 62, the other also synchronously simulates the state of meshing transmission with the driving gear 62, so that after the driving gear 62 adjusts its position, the meshing effect can be directly achieved.

[0091] It should be further explained that the height adjustment of the driving gear 62 is achieved by controlling the output distance of the electric cylinder 63. When the output distance of the electric cylinder 63 is the shortest, that is, Fig. 9In the state shown, the driving gear 62 is in meshing contact with the driven gear 2 652, and there is no suction between the upper synchronizer 151 and the connecting shaft 1 641, and there is only rotational contact between the two, and there is suction between the synchronizer 151 and the shaft seat 1 15 and they are connected as one, and there is suction between the lower synchronizer 151 and the connecting shaft 2 651 and they are connected as one, and there is no suction between the synchronizer 151 and the lower shaft seat 15, and there is only rotational contact between the two. In the above state, the driving gear 62 is driven to rotate by rotating the motor 3, so that it is driven by the transmission action of the driven gear 2 652 The output shaft 2 65 is driven synchronously to rotate, thereby making the bevel gear 2 56 rotate synchronously, and driving the rotation of the bevel gear 1 551. Under the action of the synchronous belt 1 and the influence of the installation direction of the bevel gears 2 56 on both sides, the bevel gears 1 551 on both sides can cooperate and synchronously control the same group of adjustment components 5 to perform adjustment work. Moreover, in this process, under the action of the synchronous belt 2, the driven gear 1 642 always rotates synchronously with the driven gear 2 652, so that when the driving gear 62 moves up to contact with the driven gear 1 642, it can achieve the meshing state with the driving gear 62 without adjusting the state of the driven gear 1 642.

[0092] When the output distance of the electric cylinder 63 reaches the longest, the driving gear 62 is in meshing contact with the driven gear 1 642, and there is suction between the upper synchronizer 151 and the connecting shaft 1 641 and they are connected as one, while there is no suction between the synchronizer 151 and the upper shaft seat 15, and there is only rotational contact between the two, and there is no suction between the lower synchronizer 151 and the connecting shaft 2 651, and there is only rotational contact between the two, and there is suction between the lower synchronizer 151 and the shaft seat 15. And connected as a whole, in the above state, the rotation of the driving gear 62 is controlled by rotating the motor three, so that it synchronously drives the output shaft 64 to rotate through the transmission effect on the driven gear 642, so that the movable seat 41 is moved and adjusted along the direction of the guide groove 13 under the cooperation of the threaded transmission, and the rotating motor three is stopped after it moves to the maintenance position, and then the lifting motor is started, so that the adjusting gear 43 descends to the position where it meshes with the tooth groove on the mounting plate 32 and stops, and finally the replacement of the heating element 322 is completed.

[0093] Working principle:

[0094] The reflective film mounted on the feeding roller (not shown in the figure) is fed into the furnace body 2 from the inlet and sent out of the furnace body 2 from the outlet. It is rolled up by a winding roller (not shown in the figure) on one side of the outlet. During the conveying process of the reflective film in the furnace body 2, the clamping piece on the clamping seat 53 presses down to clamp the edge of the reflective film, and transports the reflective film synchronously with the speed of the feeding roller and the winding roller. The clamping seat 53 reciprocates under the two adjacent heating components 3. By making the driving gear 62 mesh with the driven gear 2 652, the output shaft 1 64 drives the bevel gear 2 56 to rotate. The bevel gear 2 56 rotates and drives the bevel gear 1 551 to rotate, so that the rotating handle 55 rotates synchronously with it. Under the action of the T-axis, the reciprocating swing of the swing arm 58 is controlled, thereby controlling the reciprocating motion of the clamping seat 53.

[0095] When the reflective film shrinks during the heating and curing process, the clamping seat 53 will be displaced and adjusted accordingly, thereby driving the movement of the adjusting member 52 through the adjusting arm 54, causing the reset spring 512 to change in length. Under the self-restoring effect of the reset spring 512, the force is reflected on the clamping seat 53, so that the clamping seat 53 drives the reflective film to straighten, thereby alleviating the shrinkage problem during the curing process;

[0096] When it is necessary to replace the heating element 322, the driving gear 62 is switched to mesh with the driven gear 642, and then the movable seat 41 is driven to move linearly through the output shaft 64, and stops after moving to the maintenance position, and then the lifting seat 42 is lowered to make the adjusting gear 43 mesh with the tooth groove on the mounting plate 32, so that the mounting plate 32 is controlled to be moved out under the action of the adjusting gear 43. After the mounting plate 32 is moved out, the heating element 322 can be replaced.
