Description

Technical Field

[0001] This invention belongs to the field of oil curtain technology, specifically relating to an automatic pre-installation system for oil curtains. Background Technology

[0002] An oil curtain is a structure consisting of two white strips and several support strips connected together. The white strips and support strips are glued together and then pressed through two pressing processes. The support strips and white strips are arranged in a cross shape.

[0003] Existing oil curtain drying devices use a single heating plate inside the drying box. When the heating plate is activated, it generates heat to dry the glue on the moving oil curtain. However, because the two ends of the drying box are open, when the heating plate generates heat, it fills the entire interior of the drying box with heat, which is then released into the outside air through the two openings, resulting in significant heat loss.

[0004] Therefore, an automatic pre-installation system for oil curtain is needed to solve the problem in existing technologies where heat is discharged into the outside air from the open ends, causing serious heat loss. Summary of the Invention

[0039] Please see Figures 1-13This invention provides an automatic pre-installation system for oil curtains, including an automatic pre-installation device 100 for oil curtains. A drying box 101 is fixed to one side of the top surface of the automatic pre-installation device 100. A U-shaped plate 106 is provided on the top surface of the drying box 101. A second top groove 200 is opened on both sides of the top surface of the U-shaped plate 106. A plurality of evenly distributed top holes 201 are opened on the bottom surface of the inner sidewall of the second top groove 200. A sleeve post 105 is fixed in the top hole 201. A vertical rod 202 is movably engaged in the sleeve post 105. A wrapping box 203 is fixed on the bottom surface of the vertical rod 202. A heating plate 204 is fixed on the top surface of the inner sidewall of the wrapping box 203. Polyimide elastic films 205 are fixed on both sides of the inner sidewall of the wrapping box 203.

[0040] As a further embodiment of the present invention, a plurality of side rods 404 are fixed on both sides of the top surface of the U-shaped plate 106, and a rotating shaft 403 is movably connected between two opposite side rods 404 on the same side. An incomplete rotating wheel 400 is fixed on the outer wall of the rotating shaft 403, and a first connecting rope 401 is fixed to one end of the incomplete rotating wheel 400. A counterweight ball 402 is fixed to one end of the first connecting rope 401.

[0041] The incomplete rotating wheel 400 allows the counterweight ball 402 to be lifted by the incomplete rotating wheel 400, and the first connecting rope 401 allows the counterweight ball 402 to be connected to the incomplete rotating wheel 400.

[0042] As a further embodiment of the present invention, a side hole 300 is provided on the top of one side of the outer wall of the sleeve 105, an inclined block 301 is fixed near the middle position on one side of the vertical rod 202, a positioning hole 304 is provided on the bottom surface of the inner side wall of the side hole 300, a positioning post 302 is fixed on the bottom surface of the inclined block 301, the bottom of the positioning post 302 is movably engaged with the positioning hole 304, a first spring 303 is provided on the outer side wall of the positioning post 302, the top end of the first spring 303 is fixed to the bottom surface of the inclined block 301, and the bottom end of the first spring 303 is fixed to the bottom surface of the inner side wall of the side hole 300.

[0043] By using the inclined block 301, the counterweight ball 402 falls onto the inclined block 301, and the inclined surface of the inclined block 301 can limit the position of the counterweight ball 402. By using the positioning post 302 and the first spring 303, the first spring 303 can be compressed after the counterweight pushes the inclined block 301 down. After the counterweight ball 402 moves off the inclined block 301, the first spring 303 can move up, causing the vertical rod 202 to move up, and then causing the package box 203 to move up.

[0044] As a further embodiment of the present invention, a control button 800 is fixed on one side of the bottom surface of the inner wall of the first top groove 102. Two first T-shaped grooves 408 are respectively opened on one side of the inner wall of the first top groove 102. A T-shaped block 410 is movably engaged in the first T-shaped groove 408. A roller 407 is fixed between the two T-shaped blocks 410 and one end of each other. A second spring 409 is fixed on one side of the inner wall of the first T-shaped groove 408. One end of the second spring 409 is fixed to one side of the T-shaped block 410.

[0045] The first T-slot 408 and T-block 410 allow the roller 407 to be movable and restrained. The second spring 409 allows the roller 407 to be pulled back to its original position when the counterweight ball 402 separates from the inclined block 301 after it approaches the incomplete rotating wheel 400.

[0046] This solution has the following working process: When drying the oil curtain, the generated oil curtain first passes through the interior of the drying box 101, and the white strips of the oil curtain contact the bottom surface of the inner wall of the drying box 101. When the five support strips on the oil curtain are about to correspond to the five pairs of packaging boxes 203, the electric actuator 701 is activated, pushing the U-shaped rod 700. The movement of the U-shaped rod 700 drives the two first racks 502 to move. The movement of the first racks 502 drives several first gears 504 to rotate. The rotation of the first gears 504 drives the rotating shaft 403 to rotate. The rotation of the rotating shaft 403 drives the incomplete rotating wheel 400 to rotate. The rotation of the incomplete rotating wheel 400 causes the counterweight ball 402 to be placed on the inclined block 301. Then the counterweight ball 402 slides on the inclined block 301 until the counterweight ball 402 is placed on the inclined block 301. When ball 402 contacts the outer wall of vertical rod 202, the weight of counterweight ball 402 causes inclined block 301 to move downwards. This downward movement of inclined block 301 causes vertical rod 202 to move downwards, compressing the first spring 303 until the package box 203 engages with the corresponding support bar. During the incomplete rotation of wheel 400, the tension of second connecting rope 406 decreases. At this time, second spring 409 pulls roller 407 to move, causing roller 407 to roll over the surface of control button 800, thus opening control button 800. Control button 800 then activates several heating plates 204 on the corresponding side. The heating plates 204 heat to the drying temperature of the glue between the support bar and the white strip, drying the glue. Simultaneously, when package box 203 engages with the support bar, the PLC... The controller 702 starts the dual-axis motor 505, which drives the two second gears 506 to rotate. The rotation of the second gears 506 moves the U-shaped plate 106. The moving speed of the U-shaped plate 106 is the same as the moving speed of the oil curtain, so that the glue can be dried during the movement of the oil curtain. When the U-shaped plate 106 is about to move to the side away from the automatic pre-installation equipment 100 of the oil curtain, the PLC controller 702 controls the electric push rod 701 to reset, which in turn causes several rotating shafts 403 to rotate in the opposite direction. Finally, the incomplete rotating wheel 400 rotates in the opposite direction. The incomplete rotating wheel 400 rotates in the opposite direction, causing the counterweight ball 402 to move off the inclined block 301. At this time, the first spring 303 pushes the vertical rod 202 to reset, and the package box 203 resets to its initial position. At the initial height, during this process, the incomplete rotating wheel 400 rotates, pulling the second connecting rope 406 to move, causing the roller 407 to approach the incomplete rotating wheel 400. The second spring 409 is stretched, and the roller 407 moves in the opposite direction, crushing the control button 800, causing the heating plate 204 to be turned off. Subsequently, the PLC controller 702 controls the dual-axis motor 505 to rotate in the opposite direction, causing the U-shaped plate 106 to reset. After the U-shaped plate 106 resets, the five pairs of packaging boxes 203 will correspond to the next five support bars to be dried. Then, the PLC controller 702 controls the electric push rod 701 to start again, causing the counterweight ball 402 to slide onto the inclined block 301. Then, the five packaging boxes 203 engage with the five support bars, and the heating plate 204 starts to dry the glue. The above operation is repeated.The system automatically dries the oil curtain, and the dried oil curtain then proceeds to the next processing step.

[0047] The timing involved in this process is controlled by a pre-set program within the PLC controller 702.

[0048] According to the above working process: the first rack 502 and the first gear 504 enable several rotating shafts 403 to rotate synchronously, thereby enabling several incomplete rotating wheels 400 to rotate synchronously; the counterweight ball 402 and the inclined block 301 enable the vertical rod 202 to move downwards, thereby allowing the package box 203 to wrap around the support bar; the positioning post 302 and the first spring 303 enable the counterweight ball 402 to move off the inclined block 301, allowing the package box 203 to move upwards to its initial height; the second connecting rope 406 and the second spring 409 enable the roller 407 to move, thereby facilitating the crushing of the control button 8. The heating plate 204 is opened and closed by the roller 407, and the control button 800 can be opened and closed by the roller. The glue between the support strip and the white strip is dried by the heating plate 204. The wrapping box 203 can wrap the support strip by the polyimide elastic film 205. The wrapping box 203 ensures that the heating plate 204 can only dry the glue between the support strip and the white strip, thereby reducing the space for heat dissipation and avoiding the problem of heat being discharged into the outside air from the open ends of the drying box 101 when using a whole heating plate 204 for drying, which would result in serious heat loss.

[0049] As a further embodiment of the present invention, a second connecting rope 406 is fixed to one side of the roller 407, and mounting plates 405 are respectively fixed to the bottom of the outer side wall of the two incomplete rotating wheels 400 on one side, and one end of the second connecting rope 406 is fixed to one side of the mounting plate 405.

[0050] The second connecting rope 406 and the mounting plate 405 are configured to connect the incomplete rotating wheel 400 and the roller 407.

[0051] As a further embodiment of the present invention, a second T-shaped groove 500 is provided on both sides of the top surface of the U-shaped plate 106. A T-shaped strip 501 is movably engaged in the second T-shaped groove 500. A first rack 502 is fixed on the top surface of the T-shaped strip 501. A first gear 504 is fixed on the outer side of the rotating shaft 403 on both sides, close to each other. Several first gears 504 on the same side mesh with the corresponding first racks 502. A U-shaped rod 700 is fixed between one end of two first racks 502. An electric push rod 701 is fixed on one side of the top surface of the U-shaped plate 106. The output end of the electric push rod 701 is fixed to one side of the U-shaped rod 700.

[0052] The second T-slot 500 and T-strip 501 allow the first rack 502 to be movably confined. The electric push rod 701 allows the two first racks 502 to move synchronously, thereby synchronously driving the rotation of several first gears 504 on both sides.

[0053] As a further embodiment of the present invention, a second rack 503 is fixed on both sides of the top surface of the U-shaped plate 106, and a dual-axis motor 505 is fixed in the middle of the top surface of the drying box 101. A second gear 506 is fixed on the two output ends of the dual-axis motor 505, and the second gear 506 meshes with the second rack 503.

[0054] The U-shaped plate 106 can be moved by the dual-axis motor 505, the second gear 506, and the second rack 503.

[0055] As a further embodiment of the present invention, the top surface of the drying box 101 is provided with a first top groove 102 on both sides, the sleeve 105 is located in the first top groove 102, the inner sidewalls of the first top groove 102 are provided with inner grooves 103 on both sides close to each other, and the outer sidewalls of the sleeve 105 are fixed with locking blocks 104 on both opposite sides, and the locking blocks 104 are movably locked with the inner grooves 103.

[0056] The first top groove 102 allows the position of the sleeve 105 to be movably limited, and the locking block 104 and inner groove 103 further limit the position of the sleeve 105.

[0057] As a further embodiment of the present invention, a limiting frame is fixed to the top of one side of the outer wall of the sleeve 105.

[0058] By setting a limiting frame, the counterweight ball 402 can be blocked when it slides off the inclined block 301, thus preventing the counterweight ball 402 from sliding off the side of the inclined block 301.

[0059] As a further embodiment of the present invention, a PLC controller 702 is fixed on one side of the outer wall of the drying box 101. The dual-axis motor 505, the electric push rod 701 and the control button 800 are electrically connected to the PLC controller 702 respectively. Several heating plates 204 on the same side are electrically connected to the control button 800 on the same side respectively.

[0060] The entire system can be controlled programmatically by using the configured PLC controller 702.

[0061] Polyimide elastic film 205 is a high-performance polymer material with excellent high-temperature resistance. It maintains stable performance at very high temperatures, generally withstanding temperatures above 400℃ for extended periods, and even reaching 500-600℃ for short periods. Elasticity and mechanical properties: This elastic film also possesses good elasticity and mechanical properties. It has high tensile strength, capable of withstanding a certain degree of stretching without breaking. Simultaneously, its elastic recovery ability is excellent; after being stretched by an external force, it can quickly return to its original shape when the force is removed.

[0062] In summary: When drying the oil channel curtain, the generated oil channel curtain first passes through the interior of the drying box 101, causing the white strips of the oil channel curtain to contact the bottom surface of the inner wall of the drying box 101. When the five support strips on the oil channel curtain are about to align with the five pairs of packaging boxes 203, the electric actuator 701 is activated, pushing the U-shaped rod 700. The movement of the U-shaped rod 700 drives the two first racks 502 to move. The movement of the first racks 502 drives several first gears 504 to rotate. The rotation of the first gears 504 drives the rotating shaft 403 to rotate. The rotation of the rotating shaft 403 drives the incomplete rotating wheel 400 to rotate. The rotation of the incomplete rotating wheel 400 causes the counterweight ball 402 to be placed on the inclined block 301. Then the counterweight ball 402 slides on the inclined block 301 until the counterweight ball 402 aligns with the vertical rod 202. When the outer wall contacts the counterweight ball 402, the inclined block 301 moves downward due to the gravity of the counterweight ball 402. The downward movement of the inclined block 301 causes the vertical rod 202 to move downward, which in turn compresses the first spring 303 until the package box 203 engages with the corresponding support bar. When the incomplete rotating wheel 400 rotates, the tension of the second connecting rope 406 decreases. At this time, the second spring 409 pulls the roller 407 to move, causing the roller 407 to roll over the surface of the control button 800, thus opening the control button 800. The control button 800 controls the activation of several heating plates 204 on the corresponding side. The heating plates 204 heat to the drying temperature of the glue between the support bar and the white strip, thus drying the glue. At the same time, when the package box 203 engages with the support bar, the PLC controller 702 controls the dual axes. Motor 505 starts, driving two second gears 506 to rotate. The rotation of the second gears 506 moves the U-shaped plate 106. The moving speed of the U-shaped plate 106 is the same as the moving speed of the oil curtain, allowing the glue to be dried during the movement of the oil curtain. When the U-shaped plate 106 is about to move to the side away from the automatic pre-installation equipment 100 of the oil curtain, the PLC controller 702 controls the electric push rod 701 to reset, which in turn causes several rotating shafts 403 to rotate in the opposite direction, ultimately causing the incomplete rotating wheel 400 to rotate in the opposite direction. The incomplete rotating wheel 400 rotates in the opposite direction, causing the counterweight ball 402 to move off the inclined block 301. At this time, the first spring 303 pushes the vertical rod 202 to reset, and the package box 203 resets to its initial height. During this process, the incomplete Rotating wheel 400 pulls the second connecting rope 406, causing roller 407 to approach the partially rotating wheel 400. The second spring 409 is stretched, and roller 407 moves in the opposite direction, pressing the control button 800, thus shutting off the heating plate 204. Subsequently, PLC controller 702 controls the dual-axis motor 505 to rotate in the opposite direction, causing the U-shaped plate 106 to reset. Once the U-shaped plate 106 resets, the five pairs of packaging boxes 203 will align with the next five support bars to be dried. Then, PLC controller 702 again controls the electric push rod 701 to start, causing the counterweight ball 402 to slide onto the inclined block 301. The five packaging boxes 203 then engage with the five support bars, and the heating plate 204 starts to dry the glue. Repeating this operation achieves automatic drying of the oil curtain.The dried oil curtain then proceeds to the next processing step.

[0063] The timing involved in this process is controlled by a pre-set program within the PLC controller 702.

[0064] The automatic pre-installation equipment 100 for oil curtain, heating plate 204, polyimide elastic film 205, dual-axis motor 505, electric actuator 701, PLC controller 702 and control button 800 can all be purchased from the market. They are mature technologies in this field and have been fully disclosed. Therefore, they will not be described again in the manual.
