Description

Technical Field

[0001] The invention relates to the technical field of steel plate coating, in particular to a coating machine for galvanized steel plates. Background Art

[0002] Alu-zinc plate is a kind of alloy steel, which is composed of an iron matrix and an aluminum-zinc layer on the surface. Coating treatment of the galvanized plate can not only protect the coating on the surface of the plate, but also improve the surface performance, weather resistance and decorativeness of the plate.

[0003] In the patent with the announcement number CN117533578B, an aluminum plate laminating device is proposed, which can coat aluminum Great Wall plates (grating plates). By setting a side pressing mechanism for the extrusion groove and a surface pressing mechanism for the bottom of the extrusion groove, and setting a pneumatic mechanism to drive the two to move, the entire aluminum Great Wall plate (grating plate) can be laminarized. By setting an air exhaust and air pipe structure, the corner wheels of the edge pressing mechanism are pushed to move, so that the device can freely adjust the extrusion range of the edge pressing mechanism and the surface pressing mechanism according to the specifications of the aluminum plate.

[0004] However, during the extrusion process, the corner wheel and the film are in sliding contact, which will pull the film on the side of the groove, making it easy for the contact surface between the film and the plate to move relative to each other, increasing the probability of film stripping, thereby reducing the laminating effect, and there is an extrusion dead angle at the intersection of the edge pressing mechanism and the surface pressing mechanism, which is difficult to be extruded.

The two side pressure plates move sideways and press the side wall of the groove under the pressure of the laminating plate. The greater the pressure applied by the laminating plate, the greater the pressure of the side pressure plate on the side wall of the groove and the pressure of the bottom surface of the groove of the in-groove pressure plate, thereby attaching the adhesive film to the surface of the sheet and avoiding obvious sliding between the adhesive film and the sheet, reducing the pulling of the laminating mechanism on the adhesive film, and providing a rolling mechanism to increase the pressure of the laminating plate on the sheet.

Then, the laminating plate is pressed down laterally by the first cylinder and the second cylinder, so that the adhesive film is pulled outward from the static clamping plate to compensate for the extra adhesive film area required for laminating the groove, thereby avoiding the relative movement of the adhesive film and the plate due to the existence of the groove, so that the friction between the adhesive film and the plate after the adhesive film and the plate are bonded generates pulling, thereby improving the bonding effect between the adhesive film and the plate.

[0018] (3) The laminating machine for galvanized aluminum sheet is provided with a film clamping assembly and a cutter. After the cutting is completed, the electromagnet can be controlled to be energized in the reverse direction, so that the two movable film clamping plates are opened. The adhesive film near the two stationary film clamping plates loses the traction of the movable film clamping plates and is recovered with the tensioning roller under the action of the first spring, thereby entering the gap between the two stationary film clamping plates again, so as to facilitate repeated clamping of the adhesive film.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] In the description of the present invention, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0024] According to the following Figure 1 - Fig.16 A laminating machine for galvanized steel sheets provided in an embodiment of the present invention is described.

[0025] See also Figure 1-Figure 5 The embodiment of the present invention provides a technical solution: a laminating machine for galvanized aluminum sheet, comprising a bracket 1 and a bottom plate 2, the bottom plate 2 is used to carry a plate 3, the plate 3 here is a corrugated plate with a groove on the surface, and correspondingly, a receiving groove corresponding to the groove is opened on the bottom plate 2, so that the plate 3 and the bottom plate 2 can be in contact without gaps.

[0026] Combined Figure 1-Figure 4 In order to facilitate covering the surface of the plate 3 with the adhesive film, a covering and pressing mechanism is provided. The covering and pressing mechanism is installed on the bracket 1 and is located above the bottom plate 2. The covering and pressing mechanism includes a covering and pressing plate 4 and an in-groove pressing film assembly. The lower surface of the covering and pressing plate 4 can completely cover the plate 3. The in-groove pressing film assembly is installed on the lower surface of the covering and pressing plate 4 and moves with the covering and pressing plate 4. The position and number of the in-groove pressing film assembly correspond to the grooves on the plate 3 one by one. When it is necessary to cover the plate 3 with the adhesive film, the covering and pressing mechanism is driven to move downward to squeeze the plate 3. At this time, the covering and pressing plate 4 applies pressure to the non-groove surface of the plate 3, and the in-groove pressing film assembly applies pressure to the bottom and side surfaces of the groove, so that the adhesive film is completely fitted to the plate 3.

[0027] Combine 5 and Figure 6 The above-mentioned in-groove pressure film assembly includes a side pressure plate 22 and an in-groove pressure plate 23. The side pressure plate 22 is used to apply pressure to the side of the groove, and the in-groove pressure plate 23 is used to apply pressure to the bottom of the groove. A telescopic rod 24 is vertically installed on the lower surface of the covering plate 4. The bottom end of the telescopic rod 24 is fixedly connected to the in-groove pressure plate 23. The side pressure plates 22 are slidably installed between the two sides of the in-groove pressure plate 23 and the lower surface of the covering plate 4. When the covering mechanism applies pressure to the plate 3, the in-groove pressure film assembly is pressurized, thereby causing the telescopic rod 24 to shrink. At this time, the distance between the in-groove pressure plate 23 and the lower surface of the covering plate 4 is reduced, and then the two side pressure plates 22 are moved sideways under the pressure of the covering plate 4 to press the side wall of the groove. The greater the shrinkage of the telescopic rod 24, the greater the pressure of the side pressure plate 22 on the side wall of the groove and the pressure on the bottom surface of the groove of the in-groove pressure plate 23.

[0028] Optionally, in order to facilitate the adjustment of the number and position of the in-slot pressing film assembly to adapt to different panels 3, a top plate 21 can be fixed on the lower surface of the pressing plate 4, and the side pressing plates 22, the in-slot pressing plates 23 and the telescopic rods 24 can be installed on the top plate 21, so that the in-slot pressing film assembly becomes a detachable module (refer to Fig.16 ), so that the in-groove pressure film assembly and the top plate 21 are installed at different positions on the lower surface of the covering plate 4 according to needs, and at the same time, a contact plate 27 is fixed in the area on the lower surface of the covering plate 4 where the top plate 21 is not installed. The contact plate 27 is used to offset the uneven height of the lower surface of the covering plate 4 caused by the installation of the top plate 21.

[0029] Since the plate 3 is in a stationary state on the base plate 2, in order to facilitate the coating of the plate 3, a film pulling mechanism is also provided. The film pulling mechanism is installed on the bracket 1 and is located between the coating mechanism and the plate 3. The film pulling mechanism includes a film clamping assembly and a synchronous belt assembly 29. The film clamping assembly clamps one end of the film, and then, driven by the synchronous belt assembly 29, the film is pulled out and covers the top of the plate 3, thereby facilitating the coating mechanism to press the film to the upper surface of the plate 3.

[0030] Specifically, the synchronous belt assembly 29 may be composed of a motor, a pulley and a synchronous belt, and is mounted on the bracket 1 through the side plate 28 .

[0031] In addition, in order to improve the pressing force of the laminating mechanism, a rolling mechanism is provided on the bracket 1 and above the laminating mechanism. The rolling mechanism includes a pressure roller 10. The pressure roller 10 can move in the vertical direction to apply pressure downward to the laminating mechanism, and can also roll in the horizontal direction, thereby comprehensively applying pressure to the laminating mechanism, thereby improving the bonding effect between the film and the plate 3.

[0032] Combination Figure 3 and Figure 4 In order to drive the covering mechanism to move in the height direction, a first fixed block 7 is fixedly provided at the corner of one side of the upper surface of the covering plate 4, a first connecting block 9 is rotatably provided on one side of the first fixed block 7, and a first cylinder 5 is fixedly provided on the bracket 1 above the first fixed block 7, and the end of the piston rod of the first cylinder 5 is fixedly connected to the first connecting block 9, so that the height of one side of the covering plate 4 can be adjusted by the first cylinder 5.

[0033] In addition, a second fixed block 8 is fixedly provided at the corner on the other side of the upper surface of the pressure plate 4, and a displacement compensation groove 81 is opened on one side of the second fixed block 8. A second connecting block 91 is rotatably provided in the displacement compensation groove 81, and the second connecting block 91 can slide in the displacement compensation groove 81. A second cylinder 6 is fixedly provided on the bracket 1 above the first fixed block 7, and the end of the piston rod of the second cylinder 6 is fixedly connected to the second connecting block 91, so that the height of the other side of the pressure plate 4 can be adjusted by the second cylinder 6.

[0034] In this embodiment, the downward movement of the pressure plate 4 is carried out in two sides, first moving downward to the side away from the film discharge, and then moving downward to the side close to the film discharge, that is, firstly pushing the first connecting block 9 by the first cylinder 5, so that the side of the pressure plate 4 close to the first connecting block 9 moves downward to the lowest end, and then pushing the second connecting block 91 by the second cylinder 6, so that the side of the pressure plate 4 close to the second connecting block 91 moves downward to the lowest end. During the downward movement of the pressure plate 4, the second connecting block 91 slides in the displacement compensation groove 81 to avoid the pressure plate 4 from getting stuck. By moving the adhesive film downward in stages, the portion where the adhesive film is bonded to the plate 3 is fixed. As the second cylinder 6 pushes, the adhesive film is pulled outward from the discharge port to make up for the extra adhesive film area required for coating the grooves, and the adhesive film is gradually covered from one side of the plate 3 to the other side, thereby covering the entire plate 3 to avoid relative movement of the adhesive film and the plate 3 due to the presence of the grooves when the laminating plate 4 is moved downward in parallel, so that after the adhesive film and the plate 3 are bonded, traction is generated due to the friction between the two, thereby improving the bonding effect between the adhesive film and the plate 3.

[0035] In order to make the in-groove pressure plate 23 bear force evenly, a plurality of telescopic rods 24 are provided along the length direction of the in-groove pressure plate 23, and preferably, the plurality of telescopic rods 24 are equidistantly arranged.

[0036] Combination Figure 5 - Figure 7 In addition, a second spring 25 is sleeved on the outer circumference of the telescopic rod 24. The second spring 25 is compressed when the pressure plate 23 in the groove is compressed. After the pressure disappears, the second spring 25 can reset the telescopic rod 24.

[0037] Furthermore, in order to fix the side pressure plate 22, a connecting rod 26 is rotatably provided between the telescopic rod 24 and the side pressure plate 22. The height of the connecting rod 26 close to one end of the telescopic rod 24 is greater than the height close to one end of the side pressure plate 22, so that the two connecting rods 26 and the telescopic rod 24 form an umbrella-like structure. When the telescopic rod 24 is compressed, the connecting rod 26 and the end fixed to the telescopic rod 24 move downward with the covering plate 4, thereby pushing the side pressure plate 22 to move sideways. The connecting rod 26 can be a rod with flexibility.

[0038] In order to improve the coating effect on the side wall of the groove, the side surface of the side pressure plate 22 is parallel to the side surface of the groove of the plate 3, so that the side pressure plate 22 and the side surface of the groove can fit tightly.

[0039] In addition, combined Figure 6In order to facilitate the movement of the side pressure plate 22, a first slider 221 is fixedly provided on the upper surface of the side pressure plate 22, and a transverse groove 211 is opened on the lower surface of the covering plate 4, the first slider 221 slides in the transverse groove 211, and a second slider 222 is fixedly provided on the side of the lower end of the side pressure plate 22 close to the inner pressure plate 23, an inclined groove 231 is opened on the side of the inner pressure plate 23, the second slider 222 slides in the inclined groove 231, when the side pressure plate 22 is subjected to the pressure of the covering plate 4 and the thrust of the connecting rod 26, the side pressure plate 22 moves under the constraints of the transverse groove 211 and the inclined groove 231.

[0040] Specifically, the two side surfaces of the inner groove pressure plate 23 are inclined surfaces inclined toward the inner groove pressure plate 23, and the contact surfaces of the inclined groove 231 and the second sliding block 222 are parallel to the inclined surfaces of the inner groove pressure plate 23, so that the side pressure plate 22 moves sideways while moving downward.

[0041] In addition, the height of the lower surface of the side pressure plate 22 is greater than the height of the lower surface of the pressure plate 23 in the groove, thereby leaving space for the side pressure plate 22 to move downward. When the covering plate 4 contacts the upper surface of the plate 3, the side pressure plate 22 moves down to the maximum distance, and the bottom surface of the side pressure plate 22 is flush with the bottom surface of the pressure plate 23 in the groove to form a complete plane to apply pressure to the bottom surface of the groove.

[0042] Combination Figure 1 , Figure 3 , Figure 8 and Fig. 9 The above-mentioned diaphragm assembly includes two movable diaphragm plates 30 symmetrically arranged in the upper and lower parts. The distance between the two movable diaphragm plates 30 needs to be at least greater than the thickness of the film. The two movable diaphragm plates 30 are each provided with corresponding electromagnets 32. When the electromagnets 32 are energized, they adsorb each other, so that the two movable diaphragm plates 30 are attracted to each other. If the current passed is reversed, the two electromagnets 32 repel each other, so that the two movable diaphragm plates 30 are separated, thereby achieving the clamping and loosening of the film.

[0043] In addition, in order to facilitate the driving of the diaphragm assembly to move, fixing parts 34 are provided on both sides of the diaphragm assembly, and both sides of a movable diaphragm plate 30 are fixedly connected to the fixing parts 34. A limiting groove 342 is provided on the side of the fixing part 34 close to the movable diaphragm plate 30, and both sides of the other movable diaphragm plate 30 extend into the limiting groove 342, so that after the electromagnet 32 ​​is energized, the other movable diaphragm plate 30 can slide up and down under the constraint of the limiting groove 342, and the end of the fixing part 34 away from the movable diaphragm plate 30 is installed on the synchronous belt of the synchronous belt assembly 29.

[0044] Optionally, in order to improve the stability of the movement of the clamping assembly, a dovetail groove 341 can be opened on the side of the fixing member 34 close to the synchronous belt assembly 29, and a second slide rail 35 can be fixed on the side of the side plate 28 close to the fixing member 34, and the dovetail groove 341 can slide along the second slide rail 35, so that.

[0045] Combination Figure 1 and Figure 3 In order to facilitate the film clamping assembly to take the film, two static film clamping plates 31 are fixedly arranged symmetrically on one side of the bracket 1, and the film passes through the two static film clamping plates 31, and comb teeth 33 are provided on the sides facing each other of the dynamic film clamping plate 30 and the static film clamping plate 31. When clamping the film, the comb teeth 33 of the dynamic film clamping plate 30 are inserted into the comb teeth 33 of the static film clamping plate 31, so that the dynamic film clamping plate 30 and the static film clamping plate 31 are engaged with each other, so as to facilitate the film to be clamped from between the static film clamping plates 31.

[0046] Combination Fig.10 and Fig.11 A guide roller 17, a tensioning roller 18 and a reeling roller 19 are provided on one side of the bracket 1 close to the static film clamping plate 31. The guide roller 17 and the reeling roller 19 are rotatably mounted on the bracket 1, and a mounting plate 20 is fixedly provided on one side of the bracket 1. An arc groove 201 is provided on the mounting plate 20. The rotating shaft of the tensioning roller 18 passes through the arc groove 201 and can move along the arc groove 201. The reeling roller 19 is used to store the film to be used. The film is pulled out from the upper side of the reeling roller 19 and bypasses the lower side of the tensioning roller 18, and then passes through the upper surface of the guide roller 17 and then passes through the gap between the two static film clamping plates 31.

[0047] In addition, a first spring 202 is fixedly provided at the end of the rotating shaft of the tensioning roller 18, and the other end of the first spring 202 is rotatably mounted on the lower side of the mounting plate 20. When the rotating shaft of the tensioning roller 18 moves along the arc groove 201, it is always subjected to the pulling force of the first spring 202. When the film clamping assembly pulls the adhesive film, the rotating shaft of the tensioning roller 18 moves upward along the arc groove 201. At the same time, the first spring 202 also pulls the tensioning roller 18, so that the adhesive film is in a flattened state.

[0048] Optionally, for ease of installation, a rotating column 203 may be rotatably provided at the end of the rotating shaft of the tensioning roller 18 and the lower side of the mounting plate 20 , and both ends of the first spring 202 may be fixed to the two rotating columns 203 , respectively.

[0049] Combination Figure 3 , Figure 4 , Fig.12 and Fig.13 The above-mentioned rolling mechanism also includes a vertical driving assembly and a transverse driving assembly. The vertical driving assembly is used to drive the pressure roller 10 to move up and down and provide downward pressure for the pressure roller 10. The transverse driving assembly is used to drive the pressure roller 10 to move horizontally. Preferably, the axial direction of the pressure roller 10 is parallel to the length direction of the groove to achieve a better rolling effect.

[0050] The vertical drive assembly includes a third cylinder 16. The specific installation method of the third cylinder 16 is that a cross beam 15 is fixed at the upper end of the bracket 1, and a through slot 152 is opened on the cross beam 15. One end of the piston rod of the third cylinder 16 passes through the through slot 152 and is fixedly connected to the rotating shaft of the pressure roller 10. In order to facilitate the movement of the third cylinder 16, the third cylinder 16 can be fixed on a slide 153, and at the same time, a first slide rail 151 is fixed on both sides of the through slot 152 of the cross beam 15. The slide 153 cooperates with the first slide rail 151 and can slide along the first slide rail 151, thereby facilitating the horizontal movement of the third cylinder 16.

[0051] In addition, the transverse drive assembly includes a connecting member 11 arranged on both sides of the pressure roller 10, and a vertical groove 111 is opened on the side of the connecting member 11 close to the pressure roller 10. The rotating shaft of the pressure roller 10 is located in the vertical groove 111 and can move up and down. A threaded rod 13 is rotatably provided on the side of the bracket 1 close to the pressure roller 10. The threaded rod 13 is threadedly connected to a connecting member 11. A driving motor 14 is fixedly provided at one end of the threaded rod 13 on the bracket 1. The driving motor 14 is used to drive the threaded rod 13 to rotate, so that the connecting member 11 can be driven to move horizontally by the driving motor 14, and then the pressure roller 10 can be driven to move horizontally. A guide rod 12 is rotatably provided on the other side of the bracket 1 close to the pressure roller 10. The guide rod 12 is slidably connected to another connecting member 11, so that the other end of the pressure roller 10 is supported by the guide rod 12.

[0052] Combination Fig.14 and Fig.15 In order to cut the film, gaps are left between the bottom plate 2 and the bracket 1 on both sides along the moving direction of the film clamping assembly, and rodless cylinders 36 are fixedly provided on the lower surface of the bottom plate 2 near both ends of the gap, and a cutter 37 is fixedly provided on one side of the rodless cylinder 36. The cutter 37 passes upward from the gap. After the coating is completed, the two rodless cylinders 36 can drive the cutter 37 to cut the film from both sides of the plate 3. After the cutting is completed, the electromagnet 32 ​​can be controlled to be energized in the reverse direction, so that the two dynamic film clamping plates 30 are opened to facilitate the removal of the film remaining in the dynamic film clamping plates 30. The film near the two static film clamping plates 31 loses the traction of the dynamic film clamping plates 30, and is recovered with the tensioning roller 18 under the action of the first spring 202, thereby entering the gap between the two static film clamping plates 31 again.

[0053] A control unit is installed on the bracket 1, and the first cylinder 5, the second cylinder 6, the drive motor 14, the third cylinder 16, the synchronous belt assembly 29, the electromagnet 32 ​​and the rodless cylinder 36 are all electrically connected to the control unit. As for the specific connection between each component and structure and the control unit, based on the mechanical structure of this patent, technicians in this field can establish a variety of control forms according to the known technology. According to the action requirements of each mechanical component or mechanism of this patent, they can all be controlled to achieve the same purpose, so this patent will not be described in detail.

[0054] When in use (working), place the plate 3 on the bottom plate 2, and then clamp the film through the film clamping assembly. Pull the film out and cover the top of the plate 3 through the synchronous belt assembly 29, then control the first cylinder 5 to push downward, drive one side of the pressure plate 4 to move down to the lowest point, and then control the second cylinder 6 to drive the other side of the pressure plate 4 to move down to the lowest point. When the pressure plate 23 in the groove contacts the bottom surface of the groove, the pressure plate 4 continues to move downward, thereby compressing the telescopic rod 24, so that the side pressure plate 22 is pushed by the connecting rod 26 and pressed down by the pressure plate 4, and then the side pressure plate 22 moves sideways and squeezes the side wall of the groove until the pressure plate 4 moves down to the maximum distance, so that the film is pressed on the surface of the plate 3, and then the pressure roller 10 is driven by the third cylinder 16 along the vertical groove 111 on the connecting member 11 It slides downward and applies a certain pressure to the laminating plate 4 through the pressure roller 10, and then drives the threaded rod 13 to rotate through the driving motor 14, thereby driving the pressure roller 10 to move on the upper surface of the laminating plate 4 through the connecting piece 11. After the laminating is completed, the cutter 37 is driven to move by the rodless cylinder 36 to cut off the film on both sides of the plate 3. After the cutting is completed, the control electromagnet 32 ​​is reversely energized to open the two dynamic diaphragm plates 30 to facilitate the removal of the film remaining in the dynamic diaphragm plates 30. The film near the two static diaphragm plates 31 is recovered with the tensioning roller 18 under the action of the first spring 202, thereby entering the gap between the two static diaphragm plates 31 again for the next laminating use.
