Description

Technical Field

[0001] This utility model relates to the field of adhesive application equipment technology, and in particular to a roller adhesive machine for automotive interior trim. Background Technology

[0002] Generally, automotive interior trim parts are mainly composed of a plastic base material coated with adhesive and then laminated with a soft-touch surface. The soft-touch surface enhances the appearance of the parts and provides a pleasant tactile experience. Currently, an adhesive applicator is used to apply adhesive to the surface of the parts, facilitating the subsequent application of the wrapping material.

[0003] However, the current adhesive coating equipment has a relatively simple adhesive coating structure for the skin. It can only coat skin of a single specification and cannot adjust the amount of adhesive applied. As a result, it has limited functionality, poor adaptability, and cannot meet the adhesive coating needs of the diverse skins currently available. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art by providing a roller coating machine that can coat surfaces of different thicknesses, adjust the amount of glue applied, and has high coating efficiency and is easy to operate.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a roller glue machine, comprising:

[0006] A frame having a conveyor surface;

[0007] Two upright plates are arranged opposite each other on both sides of the conveyor table surface;

[0008] The drive roller and the glue-applying roller are synchronously and rotatably arranged between the two vertical plates to transfer the skin on the conveyor table.

[0009] An adjusting roller is set parallel to one side of the glue-applying roller, and the distance between the adjusting roller and the glue-applying roller forms a glue inlet for glue to enter.

[0010] The side-blocking adhesive assembly can be raised and lowered above the adhesive inlet to prevent the adhesive from flowing out from the side of the adhesive inlet;

[0011] An adhesive spraying assembly is adjustable in angle and can be raised and lowered above the adhesive inlet; wherein, the adhesive spraying assembly is used to deliver the adhesive into the adhesive inlet, and then the adhesive is applied to the surface of the conveyor table by the rotating adhesive roller.

[0012] Lifting modules, two of which are respectively located on the outside of the two upright plates, are used to drive the glue-applying roller and the adjusting roller to move up and down synchronously within the upright plates;

[0013] The skin transmission line is connected to the frame to transmit the coated skin.

[0014] In one embodiment, a drive motor is provided on one side of the upright plate to drive one end of the transmission roller to rotate, and a transmission gear is provided on the other end of the transmission roller. The transmission gear is meshed with a first gear and a second gear respectively. The first gear is disposed on the upright plate, and the second gear is connected to the glue-applying roller. The third gear is meshed with the first gear. The third gear is rotatably disposed on the lifting module. The second gear is meshed with the third gear in a lifting manner through a linkage mechanism.

[0015] In one embodiment, the lifting module includes lifting blocks disposed on both sides of the upright plate. The lifting blocks move up and down on the upright plate along the lifting slide rail via lifting cylinders. The ends of the adjusting roller and the glue-applying roller are disposed in the lifting blocks via bearings. The adjusting roller and the glue-applying roller can move up and down along the lifting grooves in the upright plates on both sides via the lifting blocks. The upright plate is provided with a reset plate disposed vertically opposite to the lifting blocks, and a reset spring is provided perpendicularly between the reset plate and the lifting blocks.

[0016] In one embodiment, the lifting block also includes an adjustment assembly for adjusting the distance between the adjusting roller and the adhesive coating roller; the adjustment assembly includes a five-star handle, which pushes a sliding block connected to the end of the adjusting roller to slide within a sliding groove of the lifting block; the sliding groove has a spring connected to the sliding block for resetting the sliding block.

[0017] In one embodiment, the side baffle assembly includes a side baffle rod disposed between two upright plates. The side baffle rod is connected to the lifting block via a connecting plate and moves along with the lifting block on the upright plates. The two ends of the side baffle rod are provided with liftable baffle blocks. The baffle blocks are disposed between the adjusting roller and the applying roller, and the two ends of the baffle blocks are respectively provided with contoured portions adapted to the surfaces of the adjusting roller and the applying roller.

[0018] In one embodiment, the glue spraying assembly includes a glue mixing rod disposed between two upright plates; the glue mixing rod moves with the lifting block, and the glue mixing rod is provided with a rotatable glue spraying bracket, which has a spray nozzle.

[0019] In one embodiment, the bottom of the conveying platform has a cavity communicating with the glue inlet.

[0020] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0021] 1. The roller coating machine of this utility model sprays the coatable glue into the glue inlet between the coating roller and the adjusting roller. The coatable glue then enters the surface of the coating roller from the glue inlet. When the coating roller rotates, it automatically coats the coatable glue onto the surface of the conveyor table. Finally, the surface conveyor line automatically collects the material. The entire processing is automated, with high coating efficiency and convenient operation.

[0022] 2. The lifting module drives the adjusting roller and the glue-applying roller to rise and fall synchronously above the horizontal platform, thereby adjusting the distance between the glue-applying roller and the drive roller to adapt to different thicknesses of the skin, making it widely adaptable.

[0023] 3. By pushing the sliding block with the five-star handle, it moves laterally within the sliding groove, thereby causing the adjusting roller to move laterally. This changes the distance between the adjusting roller and the glue applicator roller, allowing adjustment of the glue feed amount at the glue inlet between the adjusting roller and the glue applicator roller to meet different usage requirements.

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0034] This utility model provides a roller coating machine to solve the problems of existing coating equipment for skins having simple structure, being unable to adapt to skins of different thicknesses, and having difficulty adjusting the amount of glue, resulting in poor coating adaptability and inconvenient operation.

[0035] The purpose of this roller coating machine is to coat an adhesive onto a surface, in which the surface 6 in this embodiment can be any one of leather, knitted fabric, and non-woven fabric.

[0036] For ease of understanding, the specific processes in the embodiments of this application are described below. Please refer to [link / reference]. Figures 1 to 2An embodiment of this application discloses a roll coating machine, comprising a frame 1, upright plates 2, a drive roller 3, a coating roller 4, an adjusting roller 5, a side-blocking glue assembly 6, a spraying glue assembly 7, a lifting module 8, and a skin transfer line 9. The frame 1 has a conveyor table 10. Two upright plates 2 are arranged opposite each other on both sides of the conveyor table 10. The drive roller 3 and the coating roller 4 are synchronously and rotatably arranged between the two upright plates 2 to transfer the skin onto the conveyor table 10. The adjusting roller 5 is arranged parallel to one side of the coating roller 4, and the distance between the adjusting roller 5 and the coating roller 4 forms an entry point for glue application. The glue inlet; the side-blocking glue assembly 6 is height-adjustable and positioned above the glue inlet to prevent the glue flowing in from the glue inlet from flowing out from the side of the glue inlet; the glue spraying assembly 7 is height-adjustable and positioned above the glue inlet; wherein, the glue spraying assembly 7 is used to deliver the glue into the glue inlet, and then the glue coating roller applies the glue onto the skin located on the conveyor table surface when it rotates; the two lifting modules 8 are respectively located on the outside of the two upright plates 2, and are used to drive the glue coating roller 4 and the adjusting roller 5 to move up and down synchronously within the upright plate 2; the skin transmission line 9 is connected to the frame 1 to transmit the glued skin 12 out.

[0037] The roller coating machine of this utility model drives the adjusting roller 5 and the coating roller 4 to move synchronously above the horizontal platform 10 through the lifting module 8, thereby adjusting the distance between the coating roller 4 and the transmission roller 3 to adapt to different thicknesses of the skin; secondly, the entire processing is automated, with high coating efficiency and convenient operation.

[0038] As a preferred embodiment, see [reference] Figures 2 to 3 The drive motor 30 is installed on the outside of any one of the upright plates 2, and the drive motor 30 drives the transmission roller 3 to rotate. A cavity is opened at the transmission roller 3 and the glue coating roller 4 located below the conveyor table 10. At this time, the transmission roller 3 is in the cavity and located below the conveyor table 10. In this way, the skin between the transmission roller 3 and the glue coating roller 4 is conveyed to the subsequent belt conveyor 9 through the conveyor table 10.

[0039] The other end of the transmission roller 3 is provided with a transmission gear 31, which is meshed with a first gear 32 and a second gear 33 respectively; the first gear 32 is disposed on the vertical plate 2 and located to the left of the transmission gear 31, and the second gear 33 is connected to the glue-applying roller 4 and located above the transmission gear 31; the first gear 32 is meshed with a third gear 34; the third gear 34 is rotatably disposed on the lifting module 8; the second gear 33 is meshed with the third gear 34 through a linkage mechanism 35 in a liftable manner.

[0040] During normal operation, the drive motor 30 starts and drives the transmission roller 3 to rotate. The transmission gear 31 on the other side of the transmission roller 3 starts to rotate. The transmission gear 31 drives the second gear 33 to rotate. The second gear 33 drives the glue-applying roller 4 to rotate synchronously. At this time, the second gear 33 drives the third gear 34 to rotate. The direction of rotation of the third gear 34 and the second gear 33 is the same as the direction of rotation of the transmission gear 31 and the second gear 33. Thus, the transmission roller 3 and the glue-applying roller 4 rotate synchronously, thereby driving the skin 12 to be conveyed on the conveyor table 10.

[0041] When the lifting module 8 moves the glue-applying roller 4 upward, the second gear 33 connected to the glue-applying roller 4 moves upward and loses engagement with the transmission gear 31. At the same time, due to the presence of the linkage mechanism 35, the glue-applying roller 4 drives the third gear 34 to move to the right. At this time, the third gear 34 maintains engagement with the first gear 32 and the second gear 33 respectively, so that it can continue to drive the glue-applying roller 4 to rotate, thereby realizing the glue-applying roller 4 to convey the skin on the conveying table 10 and to apply glue to the skin 12.

[0042] As a preferred embodiment, see [reference] Figures 3 to 6 The lifting module 8 includes lifting blocks 80 disposed on both sides of the upright plate 2. The lifting blocks 80 are elongated and horizontally distributed on the upright plate 2. The lifting blocks 80 are raised and lowered along the lifting slide rail 82 in the Z-axis direction of the upright plate by lifting cylinders 81. The two ends of the adjusting roller 5 and the glue-applying roller 4 are disposed in the lifting blocks 80 by bearings 83, so that the adjusting roller 5 and the glue-applying roller 4 can move with the lifting blocks 80. At this time, the lifting distance of the adjusting roller 5 and the glue-applying roller 4 is limited within the lifting grooves 20 of the two upright plates 2. Through the above steps, the height of the adjusting roller 5 and the glue-applying roller 4 on the conveyor table 10 can be adjusted to adapt to skins of different thicknesses, thus providing good adaptability.

[0043] Furthermore, when the adjusting roller 5 and the glue-applying roller 4 need to be reset, the lifting cylinder 81 stops working, and the reset spring 81 between the reset plate 84 and the lifting block 80 can quickly return the adjusting roller 5 and the glue-applying roller 4 to their original positions.

[0044] Furthermore, the lifting block 80 also has an adjustment component 11 for adjusting the horizontal distance between the adjusting roller 5 and the glue-applying roller 4; the adjustment component 11 includes a five-star handle 110; the five-star handle 110 pushes the sliding block 111 connected to the end of the adjusting roller 4 to slide laterally in the sliding groove 800 of the lifting block 80; the sliding groove 800 has a spring 112 connected to the sliding block 111 for resetting the sliding block 111.

[0045] When it is necessary to adjust the distance between the adjusting roller 5 and the glue-applying roller 4 to increase or decrease the amount of glue entering the glue inlet, the sliding block is manually pushed to move laterally in the sliding groove 800 using the five-star handle 110, thereby driving the adjusting roller 4 to move laterally. When it is necessary to reset, the five-star handle 110 is manually returned to its original position, and the spring 112 helps the sliding block 111 to reset.

[0046] In one embodiment, see Figure 4 , Figure 6 and Figure 7 The side baffle assembly 6 includes two side baffles 60 disposed between two upright plates 2. The two side baffles 60 are connected to the lifting block 80 via a connecting plate 61 and move with the lifting block 80 on the upright plate. The upright plate 2 has a limiting groove for the movement of the side baffles 60. The two ends of the side baffles 60 are provided with liftable baffle blocks 62. The baffle blocks 62 are disposed between the adjusting roller 5 and the glue-applying roller 4, and the two ends of the baffle blocks 62 respectively have contoured parts 63 that are adapted to the surfaces of the adjusting roller and the glue-applying roller.

[0047] During operation, the two glue-blocking blocks 62 automatically move down between the adjusting roller 5 and the glue-applying roller 4. The contoured parts 63 at both ends of the glue-blocking blocks 62 are adapted to the surfaces of the adjusting roller 5 and the glue-applying roller 4, respectively. The middle part of the glue-blocking blocks 62 inserts and seals the two ends of the glue inlet, thereby sealing the two ends of the glue inlet and preventing the glue from flowing out from the left and right ends of the glue inlet. This ensures that the glue can only flow out from the middle part of the glue-applying roller 4, and then the rolling glue-applying roller drives the glue to be applied to the surface 12.

[0048] In one embodiment, see Figure 7 The glue spraying assembly 7 includes a glue mixing rod 70 disposed between two upright plates 2; the glue mixing rod 70 moves with the lifting block 80, and the glue mixing rod 80 is provided with a manually rotatable glue spraying bracket 71. The glue spraying bracket 71 has a nozzle, and the angle of the nozzle can be adjusted according to actual usage requirements. In addition, in this embodiment, the nozzle sprays out an applicable glue, which then flows from the glue inlet onto the surface of the glue coating roller.

[0049] In one embodiment, the bottom of the conveyor table 10 has a cavity 13 communicating with the glue inlet. At this time, the nozzle sprays pure water, which can automatically clean the surfaces of the adjusting roller 5 and the glue coating roller 4. Then, the wastewater flows into the cavity 13 through the glue inlet and is discharged from the drain outlet.

[0050] In this embodiment, the coating method for applying adhesive to the skin 12 includes the following steps:

[0051] S1 adjusts the glue application roller 4 and the adjusting roller 5 to the set height according to the product to be glued by controlling the lifting cylinder 81 to match the thickness of the skin 12, and manually adjusts the five-star handle 110 to adjust the distance between the glue application roller 4 and the adjusting roller 5 to adjust the glue application amount.

[0052] S2 places the skin 12 to be coated onto the conveyor table 10, positioning it between the drive roller 3 and the coating roller 4;

[0053] S3 starts the nozzle valve, and the nozzle sprays the adhesive into the glue inlet. The two ends of the glue inlet are sealed by glue-blocking blocks, so the adhesive flows down along the middle of the glue inlet onto the glue roller.

[0054] As the S4 coating roller 4 is driven to rotate by the transmission roller 3, it simultaneously conveys the skin 12 forward and rotatably applies the coating adhesive from its own surface onto the skin.

[0055] The S5 coated skin continues to be conveyed forward and flows out onto the belt conveyor line;

[0056] S6 The coated outer layer can be collected manually at the end of the belt conveyor.

[0057] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
