Description

Technical Field

[0001] The invention relates to the technical field of film coating, in particular to a steel plate film coating device for automated sandwich panel production. Background Art

[0002] Sandwich panels consist of double-layer metal panels (such as galvanized steel panels, aluminum alloy panels) and a core material in the middle. The core material includes rigid polyurethane (PUR), rock wool, polystyrene (EPS), etc. Its structure is similar to a "sandwich" and is formed by hot pressing composite molding. The total thickness is between 50-300mm, and the panel thickness is usually 0.2-1.0mm. The steel plate laminating device for automated sandwich panel production is used in the production of sandwich panels and can perform laminating treatment on the sandwich panels.

[0003] According to Chinese patent publication number CN118205197A, a steel plate coating device for sandwich panel production is disclosed, wherein the transport component includes a track and a traction device; the track is arranged inside the inner wall of the support plate; a power component is arranged inside the track; the traction device includes a slider, a support block and a clamping block; the slider is arranged inside the track and slides along the track under the action of the power component; the support block is fixedly mounted on the slider, and the clamping block is slidably mounted on the other end of the support block; the transport component clamps the metal film with the clamping block under the control of an electrical signal, and carries the metal film along the track through a grinding roller, a bonding roller, a tightening roller and a coating roller in sequence. After the metal film reaches the coating roller, the clamping block releases the metal film under the control of the electrical signal, and returns along the track to a position on the vertical track close to the discharge roller for the next cycle operation, so as to realize automated operation, reduce manual operation, and achieve the purpose of improving production efficiency.

[0004] At present, the existing automatic sandwich panel production steel plate laminating device and the above-mentioned case are not convenient for longitudinal laminating when in use. The traditional laminating device adopts transverse laminating and cannot perform double-sided laminating at the same time. At the same time, it is impossible to perform contact limiting work more stably, so that the sandwich panel can be better pressed. Therefore, improvements are made to the above-mentioned problems. Summary of the invention

[0005] In view of the problems in the prior art, the present invention provides a steel plate coating device for automated sandwich panel production.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a steel plate laminating device for automated sandwich panel production, comprising a support and limiting structure, wherein a side end of the support and limiting structure is fixed to a first support structure, a side of the support and limiting structure facing away from the first support structure is fixed to a second support structure, and a laminating pressing structure is provided at a position limit between the first support structure and the second support structure;

[0007] The support and limit structure is used for the top limit of the core board and the steel plate film. The hydraulic control seat controls the height of the limit rotating wheel through the side frame and the control motor, and the limit rotating wheel rotates under the control of the control motor.

[0008] The first support structure is the same as the second support structure. The first support structure and the second support structure are symmetrically arranged and are used for the double-pass exhaust work.

[0009] The film laminating and pressing structure is used for the lamination of the steel plate film and the core board. The telescopic control seat changes the positions of the limit bottom wheel and the pushing folding frame through the telescopic control rod. The limit bottom wheel performs the bottom limit of the core board and the steel plate film. The hydraulic adjustment rod changes the lateral position of the guiding transmission roller. And the symmetrically arranged sliding blocks, hinge rods and support sleeve frames form a triangular structure. The semi-toothed disc drives the support vertical rod to rotate through the swing rod, and the electric telescopic rod controls the rotation adjustment of the pressing roller. The steel plate film is transmitted and guided through the pressing roller and the guiding transmission roller, and the steel plate film and the core board can be brought into secondary contact.

[0010] Specifically, the support and limit structure includes a support plate, on which a hydraulic control seat is installed.

The rear end of the suction fan is communicated with a guide exhaust pipe, and both sides of the bottom of the suction fan are communicated with a first air duct and a second air duct.

[0012] Specifically, the film laminating and pressing structure includes a first guiding component and a second guiding component. The first guiding component and the second guiding component are symmetrically arranged and are used for the transmission of the steel plate film. The core board is transmitted on the transmission component, and the side end of the transmission component is fixed to the bottom plate. The bottom plate is provided with a pressing component, and the pressing component is used for the lamination treatment of the core board and the steel plate film.

[0013] Specifically, the first guiding component includes a bottom support plate, on which a bottom support frame is fixedly provided. The bottom support frame is fixed to a docking shaft through a vertical roller, and a guiding roller is rotatably connected to the docking shaft. Through the structural setting of the transmission component, the position of the telescopic control rod can be changed through the telescopic control seat, so that the telescopic control rod drives the pushing folding frame to move, and the limit bottom wheel rotates and contacts the core board and the steel plate film to perform the limit treatment work. The steel plate film is transmitted in the center of the vertical roller and the guiding roller, which is convenient for the guiding transmission work of the steel plate film.

[0014] Specifically, the transmission component includes a transmission roller, and a telescopic control seat is fixedly provided at the side end of the transmission roller. The telescopic control seat changes the position of the pushing folding frame through the telescopic control rod, and a limit bottom wheel is rotatably connected to the pushing folding frame.

[0015] Specifically, the pressing component includes a fixed frame block, a track plate is fixed on the fixed frame block, and the track plate is limited by a limiting circular shaft to control the position of the regulating mechanism. Through the structural setting of the pressing component, the core plate and the steel plate membrane can be pressed together. The steel plate membrane is transmitted on the squeezing roller and the guide transmission roller, and then guided to the symmetrical squeezing roller to form a wave structure. The steel plate membrane can be controlled to contact the core plate for the second time. During the first contact, the excess colloid on the steel plate membrane can be coated on the core plate. The secondary structure is contacted at the symmetrical squeezing roller for squeezing limitation. The position of the symmetrical squeezing roller can be adjusted by an electric telescopic rod, and the spacing with the guide transmission roller can be controlled separately. The hydraulic adjustment rod changes the position of the support sleeve by extension and contraction, so that the support guard plate changes the position of the guide transmission roller and changes the spacing between the steel plate membrane and the core plate, thereby facilitating the docking and installation of the steel plate membrane. When the hydraulic adjustment rod controls the movement, the sliding block cooperates to move, and the articulated rod is swung and adjusted by the articulated shaft to change the angle relationship. The symmetrically arranged sliding blocks, articulated shafts, and articulated rods form a triangular structure to improve the connection stability.

[0016] Specifically, the control mechanism includes a hydraulic adjustment rod, the side end of the hydraulic adjustment rod is limited by the support sleeve, a motor seat is fixedly installed on the support sleeve, the lower end of the support sleeve is hinged to the hinged rod, the hinged rod is hinged to the sliding block through the hinge shaft, and the motor seat is limited by the support guard plate to guide the transmission roller to rotate on the support guard plate, and is provided with an independent motor drive.

The squeezing roller is connected to the sleeve through the support base and the telescopic docking block, and can be rotated and adjusted by the center position of the sleeve, so that when the support rail moves, the squeezing roller can be pulled to change its position, thereby changing the spacing between the squeezing roller and the guide transmission roller. The electric telescopic rod can squeeze the squeezing roller through the telescopic adjustment of the telescopic docking block, and change the spacing position of the core plate and the steel plate membrane through the squeezing roller.

[0018] Specifically, the sliding block, hinged shaft, and hinged rod are arranged in a double layer. The sliding block slides on the limiting circular shaft, the hydraulic adjustment rod is fixed to the side of the supporting frame, the steel plate film is transmitted between the guide roller and the vertical roller, and the steel plate film slides and is transmitted on the transmission roller.

[0019] Beneficial effects of the present invention:

[0020] 1. Through the structural design of the pressing component, the present invention can perform the pressing process of the core board and the steel plate film. The steel plate film is transported on the extrusion rollers and the guiding and transporting rollers, and then guided to the symmetric extrusion rollers to form a wave structure. Through control, the steel plate film can make secondary contact with the core board. During the first contact, the excess colloid on the steel plate film can be coated on the core board. The secondary structure is the contact at the symmetric extrusion rollers for extrusion and limiting. Moreover, the position of the symmetric extrusion rollers can be adjusted by the electric telescopic rod, and the distance from the guiding and transporting rollers can be controlled individually. The hydraulic adjusting rod changes the position of the support sleeve through telescoping, causing the support guard plate to change the position of the guiding and transporting rollers, thereby changing the distance between the steel plate film and the core board, facilitating the docking and installation of the steel plate film. When the hydraulic adjusting rod controls the movement, the sliding block moves in cooperation, and the articulated rod swings and adjusts through the articulated shaft to change the angular relationship. The symmetrically arranged sliding blocks, articulated shafts, and articulated rods form a triangular structure, improving the connection stability performance.

[0021] 2. Through the structural design of the motor base, the motor base drives the semi-toothed disk to rotate, changing the angles of the swing rod and the support vertical rod. The extrusion roller is connected to the sleeve through the support clamping seat and the telescopic docking block, and can be rotationally adjusted through the center position of the sleeve. Thus, when the support vertical rod moves, the extrusion roller can be pulled to change its position, altering the distance between the extrusion roller and the guiding and transporting rollers. The electric telescopic rod adjusts the extrusion roller through the telescopic adjustment of the telescopic docking block, changing the distance position between the core board and the steel plate film through the extrusion roller.

[0022] 3. Through the structural design of the transmission component, the position of the telescopic control rod can be changed by the telescopic control seat, causing the telescopic control rod to drive the pushing and folding frame to move, enabling the limiting bottom wheel to make rotational contact with the core board and the steel plate film for the limiting process. The steel plate film is transported in the center of the vertical rollers and the guiding rollers, facilitating the guiding and transporting of the steel plate film.

[0023] 4. Through the structural design of the support and limiting structure, the hydraulic control seat changes the positions of the control motor and the limiting runner through the telescopic frame. The control motor controls the rotation of the limiting runner to limit the upper core board and the steel plate film. The exhaust fan is connected through the first air duct and the second air duct to perform the two-way exhaust treatment. The rear end of the exhaust fan is connected to the external purification equipment through the exhaust pipe for connection treatment. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The film laminating structure 4 includes a first guiding component 16 and a second guiding component 17. The first guiding component 16 and the second guiding component 17 are symmetrically arranged and are used for transmitting the steel plate film 19. The core plate 18 is transmitted on the transmission component 20, and the side end of the transmission component 20 is fixed to the bottom plate 21. A laminating component 22 is arranged on the bottom plate 21, and the laminating component 22 is used for laminating the core plate 18 and the steel plate film 19.

[0050] The pressing component 22 includes a fixed frame block 35. A track plate 34 is fixedly provided on the fixed frame block 35, and the track plate 34 limits the regulating mechanism 33 through a limiting round shaft 36.

[0051] The regulating mechanism 33 includes a hydraulic regulating rod 39. The side end of the hydraulic regulating rod 39 is limited to the support sleeve frame 38. A motor seat 37 is fixedly installed on the support sleeve frame 38. The lower end of the support sleeve frame 38 is hinged to a hinge rod 42. The hinge rod 42 is hinged to a sliding block 40 through a hinge shaft 41. The motor seat 37 limits the guiding transmission roller 52 through a support guard plate 53. The guiding transmission roller 52 rotates on the support guard plate 53 and is driven by an independent motor. The steel plate film 19 reaches the pressing component 22 through the guiding roller 24 and the vertical roller 25. The steel plate film 19 is transmitted on the pressing roller 49, the guiding transmission roller 52 and the symmetrically arranged pressing rollers 49, and is transmitted in a wavy arc shape. The user can drive and control through the motor seat 37 to drive the half gear disc 43 to rotate. The half gear discs 43 are symmetrically arranged and can cooperate to rotate. The rotation of the half gear disc 43 can drive the swing rod 44 to move cooperatively, so that the support vertical rod 45 adjusts the angle, changes the position of the pressing roller 49, so that the pressing roller 49 drives the sleeve piece 46 to rotate and adjust through the connecting guide rod frame 50 and the telescopic docking block 51, changes the distance between the support clamping seat 48 and the connecting guide rod frame 50, and then the electric telescopic rod 47 extends to change the position of the connecting guide rod frame 50, so that the connecting guide rod frame 50 drives the telescopic docking block 51 to extend and adjust, so that the pressing roller 49 is pushed and adjusted through the support clamping seat 48 until the pressing roller 49 contacts the steel plate film 19 again, which is convenient for guiding and connecting the steel plate film 19 on the guiding transmission roller 52 after a roll of production is completed, and is convenient for introducing a new steel plate film 19 onto the guiding transmission roller 52 again.

[0052] A half-toothed disc 43 is drivingly connected to the motor base 37. A swing rod 44 is fixedly arranged on the half-toothed disc 43. A support vertical rod 45 is fixedly arranged on the swing rod 44. An electric telescopic rod 47 is hingedly arranged on the support vertical rod 45. The electric telescopic rod 47 is hingedly connected to the connecting guide rod frame 50. The connecting guide rod frame 50 is telescopically connected to the sleeve piece 46 through a telescopic docking block 51. And the sleeve piece 46 is rotatably connected to the lower end of the hinge rod 42. One side of the telescopic docking block 51 facing away from the sleeve piece 46 is fixed to the support clamping seat 48. A pressing roller 49 is rotatably arranged on the support clamping seat 48. The telescopic adjustment of the support sleeve frame 38 can be controlled by the hydraulic adjustment rod 39 to change the position of the support guard plate 53, so that the support guard plate 53 drives the guiding transmission roller 52 to adjust the position. The steel plate film 19 is introduced from the side of the pressing roller 49 facing away from the support clamping seat 48, and then winds around to the rear end of the guiding transmission roller 52 and is guided out through the front end of the symmetrical pressing roller 49. The two pressing rollers 49 can press the steel plate film 19 and the core plate 18 twice. The first time can make them fit and coat the excess colloid. The pressing roller 49 at the rear end controls the extrusion of the steel plate film 19 and the core plate 18 to realize the fixed fitting work of the core plate 18 and the steel plate film 19. The rotation angle of the half-toothed disc 43 is controlled within 70°.

[0053] The sliding block 40, the hinge shaft 41, and the hinge rod 42 are arranged in a double layer. The sliding block 40 slides on the limiting circular shaft 36. The hydraulic adjustment rod 39 is fixed to the side of the support vertical frame 15. The steel plate film 19 is transmitted between the guiding roller 24 and the vertical roller 25. The steel plate film 19 slides and is transmitted on the transmission roller 28. During the pushing process of the hydraulic adjustment rod 39, at this time, the support sleeve frame 38 can drive the hinge rod 42 to move in cooperation. At this time, the hinge rod 42 slides on the limiting circular shaft 36 through the sliding block 40. At the same time, the hinge rod 42 is hingedly connected to the sliding block 40 through the hinge shaft 41 and can change the angle to prevent jamming. At the same time, it improves the stability of the overall adjustment structure of the control mechanism 33 and facilitates covering the steel plate film 19 on the surface of the core plate 18.

[0054] The working principle is as follows: When in use, the steel plate film 19 is transmitted between the guiding roller 24 and the vertical roller 25, and the core plate 18 is also continuously introduced into the film covering and pressing structure 4. At this time, the transmission roller 28 rotates to control the longitudinal transmission of the core plate 18. At this time, the telescopic control seat 32 controls the telescopic control rod 31 to extend, so that the limiting bottom wheel 29 on the pushing folding frame 30 contacts the core plate 18 and the steel plate film 19 to perform bottom limiting;

[0055] At the same time, the hydraulic control seat 6 controls the height adjustment of the telescopic frame 7, so that the limiting rotating wheel 10 contacts the upper ends of the core plate 18 and the steel plate film 19. At this time, the control motor 9 can control the rotation of the limiting rotating wheel 10, so that the core plate 18 and the steel plate film 19 move. At the same time, the limiting rotating wheel 10 performs the top limiting work on the core plate 18 and the steel plate film 19;

[0056] The exhaust fan 11 is started and connected to the first air outlet pipe 13 and the second air outlet pipe 14, so as to extract and exhaust the internal air and guide and transmit it through the exhaust pipe 12, thereby performing environmentally friendly production work;

[0057] Among them, the steel plate film 19 reaches the pressing component 22 through the guide roller 24 and the vertical roller 25. The steel plate film 19 is transmitted on the squeezing roller 49, the guide transmission roller 52 and the symmetrically arranged squeezing roller 49, and is transmitted in a wavy arc shape. The user can drive and control it through the motor seat 37 to drive the half-toothed disc 43 to rotate. The half-toothed disc 43 is symmetrically arranged, which can make the two half-toothed discs 43 rotate in coordination. The rotation of the half-toothed disc 43 can drive the swing rod 44 to move in coordination, so that the support vertical rod 45 can adjust the angle, change the position of the squeezing roller 49, and make the squeezing roller 49 pass The connecting guide rod frame 50 and the telescopic docking block 51 drive the sleeve 46 to rotate and adjust, changing the distance between the support base 48 and the connecting guide rod frame 50. Then the electric telescopic rod 47 extends to change the position of the connecting guide rod frame 50, so that the connecting guide rod frame 50 drives the telescopic docking block 51 to extend and adjust, so that the squeezing roller 49 is pushed and adjusted through the support base 48, and adjusted until the squeezing roller 49 contacts the steel sheet film 19 again, which can facilitate the guide connection of the steel sheet film 19 on the guide transmission roller 52 after the steel sheet film 19 completes the production of one roll, and facilitates the introduction of a new steel sheet film 19 onto the guide transmission roller 52 again;

[0058] After the adjustment is completed, the support sleeve 38 can be controlled to be telescopically adjusted through the hydraulic adjustment rod 39 to change the position of the support guard plate 53, so that the support guard plate 53 drives the guide transmission roller 52 to adjust the position, and the steel plate film 19 is introduced through the squeezing roller 49 to the side away from the support card seat 48, and then goes around to the rear end of the guide transmission roller 52, and is discharged through the front end of the symmetrical squeezing roller 49. The two squeezing rollers 49 can press the steel plate film 19 and the core plate 18 twice. The first time can fit them together and coat the excess colloid. The squeezing roller 49 at the rear end controls the squeezing of the steel plate film 19 and the core plate 18 to achieve fixed fitting of the core plate 18 and the steel plate film 19. The rotation angle of the half toothed disc 43 is controlled within 70 degrees.

[0059] During the movement of the hydraulic adjustment rod 39, the support sleeve 38 can drive the articulated rod 42 to move in coordination. At this time, the articulated rod 42 slides on the limiting circular shaft 36 through the sliding block 40. At the same time, the articulated rod 42 is hinged to the sliding block 40 through the articulated shaft 41, which can change the angle to prevent jamming. At the same time, it improves the stability of the overall adjustment structure of the control mechanism 33, making it convenient to cover the steel plate membrane 19 on the surface of the core plate 18.
