Description

Technical Field

[0001] This utility model relates to a glue dispensing mechanism, and more specifically to a glue dispensing mechanism for a roll glue machine. Background Technology

[0002] In general, soft-covered surfaces in automotive interior trim parts require adhesive application before use. Existing methods mostly employ roller coating machines to apply the adhesive. For example, patent application number 202110834415.9, entitled "Apparatus and Method for Applying Adhesive to Automotive Interior Trim Surfaces," describes a process where adhesive is delivered via a delivery pipe to an application roller, and the upper surface is conveyed by a conveyor belt between the application roller and the drive roller for adhesive application.

[0003] However, in actual use, it was found that the glue dispensing method is to transfer the glue to the glue roller through the glue outlet on the glue supply pipe, and then the glue roller applies it to the product. In this way, the uniformity of the glue entering the glue roller cannot be guaranteed, and the thickness of the glue applied to the skin cannot be adjusted. The coating accuracy is poor, and the glue amount cannot be effectively controlled, which cannot meet the glue application needs of the existing multi-specification skin. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art by providing a glue dispensing mechanism for a roller glue machine, which has good glue uniformity, high coating accuracy, and can adjust the thickness of the glue applied to the product in real time, and has wide adaptability.

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

[0006] frame;

[0007] The upper roller is rotatably mounted on the frame;

[0008] An adhesive dispensing assembly is mounted on the frame and is movable relative to the upper roller to apply adhesive to the surface of the upper roller as the upper roller rotates.

[0009] Side sealing assembly, two side sealing assemblies are disposed on both sides of the dispensing assembly, and the two side sealing assemblies can move relative to the two ends of the upper roller respectively;

[0010] A scraping assembly is disposed on the glue conveying assembly and distributed along the length of the glue conveying assembly on one side of the upper roller.

[0011] When the two side sealing adhesive groups seal both ends of the upper roller, the adhesive delivery assembly drives the adhesive scraper assembly to move to one side of the upper roller. When the adhesive delivery assembly moves, it sprays adhesive onto the upper surface of the adhesive scraper assembly. Then, the adhesive flows along the front end of the adhesive scraper assembly into the adhesive application space and applies the adhesive to the surface of the upper roller. When the upper roller rotates, the adhesive scraper assembly scrapes the adhesive on the surface of the upper roller. Finally, when the upper roller rotates, it applies adhesive to the surface of the upper roller.

[0012] Furthermore, the glue dispensing assembly includes screw drive mechanisms disposed on both sides of the frame, the two screw drive mechanisms driving a receiving frame located within the frame to slide relative to the upper roller; a rodless cylinder is provided at the top of the receiving frame, the rodless cylinder is provided with a flow channel that can move laterally above the receiving frame, the flow channel is connected to an external glue tank; the outlet of the flow channel points to the upper surface of the glue scraper assembly; a glue trough is provided below the glue scraper assembly on the frame.

[0013] Furthermore, the flow channel is L-shaped.

[0014] Furthermore, the side sealing assembly includes a sealing block that can move laterally at the end of the upper roller via a sealing cylinder, the sealing cylinder being disposed on the receiving frame; wherein, when the sealing block moves to a set position, the sealing block seals one side end of the upper roller.

[0015] Furthermore, the adhesive scraping assembly includes an adhesive scraping bracket, which is disposed at the front end of the receiving frame. The adhesive scraping bracket is provided with scrapers distributed along the length direction of the upper roller, and the scrapers are inclined downward toward one side of the upper roller. The front end of the scraper and the upper roller form the adhesive application space.

[0016] Furthermore, the rodless cylinder also has a liquid level sensor that moves synchronously with the flow channel to sense the liquid level of the adhesive on the upper surface of the adhesive scraping assembly.

[0017] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0018] This utility model's roller coating machine uses a glue dispensing mechanism. Two side sealing glue groups seal both ends of the upper roller to prevent glue from flowing out from both sides of the upper roller, ensuring that the glue remains on the upper roller. When the glue feeding component slides laterally, the sprayed glue flows down into the glue scraper bracket and then into the scraper, so that the glue is evenly distributed on the scraper. When a certain amount of glue remains on the scraper, it scrapes, and the glue is applied to the surface of the upper roller from the front end of the scraper component along the glue coating space. At the same time, when the upper roller rotates clockwise, the scraper scrapes off the excess glue on the upper surface of the upper roller. Then, when the upper roller rotates clockwise, the glue is evenly applied to the product. The whole process is automated, with high production efficiency, good coating uniformity and high precision. At the same time, the distance between the scraper and the upper roller can be adjusted to adjust the thickness of the glue applied to the product. Attached Figure Description

[0026] 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.

[0027] This invention provides a glue dispensing mechanism for a roller coating machine to solve the problems of poor glue dispensing uniformity, difficulty in adjusting the thickness of the coating on the surface, and low glue quality in the prior art when coating the surface.

[0028] For ease of understanding, the specific processes in the embodiments of this application are described below. Please refer to [link / reference]. Figure 1 An adhesive dispensing mechanism for a roller glue machine according to an embodiment of this application includes a frame 1, an upper roller 2, an adhesive conveying assembly 3, a side sealing assembly 4, and a scraping assembly 5. The upper roller 2 is rotatably mounted on the frame 1. The adhesive conveying assembly 3 is mounted on the frame 1 and is movable relative to the upper roller 2 to apply adhesive to the surface of the upper roller 2 when the upper roller 2 rotates. Two side sealing assemblies 4 are mounted on both sides of the adhesive conveying assembly 3, and the two side sealing assemblies 4 are movable relative to the two ends of the upper roller 2, respectively. The scraping assembly 5 is mounted below the adhesive conveying assembly 3 and is distributed along the length of the upper roller 2, and a glue application space is formed between the front end of the scraping assembly 5 and the upper roller 2.

[0029] This utility model discloses a glue dispensing mechanism for a roller glue machine. Two side sealing glue groups 4 seal both ends of the upper roller 2 to prevent glue from flowing out from both sides of the upper roller. The glue conveying component 3 drives the glue scraping component 5 to move to one side of the upper roller 2. When the glue conveying component 3 moves, it sprays glue onto the upper surface of the glue scraping component 5. Then, the glue flows along the front end of the glue scraping component 5 into the glue coating space and coats the surface of the upper roller. Finally, when the upper roller rotates, the glue is coated onto the surface of the upper roller. The glue scraping component 5 scrapes the glue on the surface of the upper roller 2 while the upper roller 2 rotates to ensure the thickness of the glue. The entire glue dispensing process is fully automated, with good glue dispensing effect and adjustable glue thickness.

[0030] based on Figures 1 to 3In a preferred embodiment, the glue dispensing assembly 3 includes screw drive mechanisms 30 disposed on both sides of the frame 1. The two screw drive mechanisms 30 synchronously drive the receiving frame 31 located within the frame 1 to slide parallel to the upper roller 2. A glue trough 33 is located below the receiving frame 31 on the frame 1. A rodless cylinder 34 is located at the top of the receiving frame 31, and the rodless cylinder 34 has a flow channel 35 that moves along the length of the upper roller 2. One end of the flow channel 35 is connected to an external glue tank. The outlet of the flow channel 35 points towards the upper surface of the scraper assembly 5. The glue trough 33 is located below the scraper assembly 5 on the frame 1. During operation, the flow channel 35 moves laterally left and right to drip glue onto the upper surface of the scraper assembly 5. When the glue is evenly distributed on the scraper assembly 5, the glue flows in from the coating space between the scraper assembly 5 and the upper roller, thereby evenly coating the glue onto the upper roller 2.

[0031] Furthermore, based on Figure 2 The flow channel 35 is L-shaped, and one end of the flow channel 35 is connected to the external glue bucket, while the other end is open towards the upper surface of the glue scraper assembly 5. The glue in the glue bucket can enter the upper surface of the glue scraper assembly 5 through the flow channel 35, and then flow into the glue application space formed between the glue scraper assembly 5 and the upper roller and be applied to the surface of the upper roller. A portion of the glue flows directly into the glue tank 33.

[0032] Furthermore, based on Figure 1 The rodless cylinder 34 also has a liquid level sensor 36 that moves synchronously with the flow channel 35 to sense the liquid level of the glue on the upper surface of the glue scraper assembly 5. This allows for real-time detection of the amount of glue on the upper surface of the glue scraper assembly 5, ensuring accurate glue application.

[0033] For further details, please refer to [link / reference]. Figures 3 to 5 The side sealing assembly 4 includes sealing blocks 41 that can move laterally at the end of the upper roller 2 via sealing cylinders 40. The sealing cylinders 40 are mounted on the receiving frame 31. During operation, the sealing cylinders 40 on both sides synchronously drive the sealing blocks 41 to move towards the end of the upper roller 2. The movement stops when the two sealing blocks 41 are attached to both ends of the upper roller 2. In this way, the two sealing blocks 41 seal both ends of the upper roller 2, and the glue will not flow out from both ends of the upper roller 2, but will remain on the surface of the upper roller 2, which facilitates the glue application operation on the upper roller 2 and ensures good glue uniformity.

[0034] In addition, the sealing block 41 is made of silicone, which ensures that the sealing block 41 has a good seal on both sides of the upper roller 2.

[0035] Furthermore, the scraper assembly 5 is disposed on the receiving frame 31 on one side of the upper roller 2, and the scraper assembly 5 can move laterally relative to the upper roller 2 along with the receiving frame 31. The scraper assembly 5 includes a scraper bracket 50, which is inclined downward toward one side of the upper roller 2 and is disposed at the front end of the receiving frame 31. The scraper bracket 50 is provided with scrapers 51 that are distributed along the length direction of the upper roller 2 and inclined toward one side of the upper roller 2. When the scrapers 51 move with the receiving frame 31, the thickness of the adhesive applied to the product is adjusted by the distance between the scrapers 51 and the upper roller 2. And since the scrapers 51 are distributed along the length direction of the upper roller 2, excess adhesive on the upper roller 2 can be scraped off evenly, ensuring that the adhesive thickness applied to the product by the upper roller 2 is uniform and the coating quality is high.

[0036] During operation, the two lead screw drive mechanisms 30 drive the receiving frame 31 to move towards the upper roller 2 to a set position and then stop. The distance of movement is determined by the thickness of the adhesive applied to the product, i.e., the distance between the front end of the scraper 51 and the upper roller 2. The external glue bucket flows the adhesive into the scraper support 50 inclined to one side of the upper roller 2 through the flow channel 35, and then flows down to the scraper 51. At this time, the flow channel 35 is driven to move laterally left and right by the rodless cylinder 34, so that the adhesive is evenly coated on the upper surface of the scraper 51. Then the adhesive on the scraper 51 can flow out evenly from the glue application space and apply the adhesive to the surface of the upper roller 2. Then the upper roller 2 starts to rotate clockwise. When the upper roller 2 rotates clockwise, it applies the adhesive to the surface of the product. At the same time, the adhesive flowing from both ends of the upper roller 2 is blocked by the sealing block 41, so that the adhesive can only stay on the surface of the upper roller 2.

[0037] Simultaneously, as the upper roller 2, coated with adhesive, continues to roll clockwise, the scraper 51 scrapes off the adhesive on the surface of the upper roller 2 at a certain thickness, ensuring even distribution of the adhesive. Finally, the surface of the upper roller 2 applies the adhesive to the product located below it, quickly completing the adhesive application process with high precision. Furthermore, because the distance between the tip of the scraper 51 and the upper roller 2 is adjustable, adhesive of varying thicknesses can be applied to the product via the upper roller 2.

[0038] See Figures 1 to 5 The entire workflow of this utility model is as follows:

[0039] Two lead screw drive mechanisms 30 drive the receiving frame 31 to move towards the upper roller 2 to a set position. At this time, the distance between the scraper 51 and the upper roller 2 is the thickness coated on the product.

[0040] Driven by the sealing cylinder, the two sealing blocks move toward both ends of the upper roller until they seal both ends of the upper roller.

[0041] The external glue bucket flows the glue into the scraper holder 50 through the flow channel 35, and then the glue flows down to the scraper 51. At this time, the flow channel 35 is driven by the rodless cylinder 34 to move horizontally left and right so that the glue is evenly coated on the upper surface of the scraper 51.

[0042] When a certain amount of glue remains on the scraper, most of the glue flows from the glue application space onto the surface of the upper roller, and a small amount falls into the glue tank.

[0043] When the upper roller 2 starts to rotate clockwise, the scraper 51 scrapes off the glue on the surface of the upper roller 2 to a certain thickness, so that the glue can be evenly distributed on the surface of the upper roller. Then, when the upper roller rotates to a certain position, the glue is evenly applied to the product located below the upper roller.

[0044] The glue dispensing mechanism of this invention's roller glue machine can stably and evenly coat the glue onto the upper roller, and the thickness of the coated glue is adjustable, resulting in high quality and precision of glue application, meeting actual processing needs.

[0045] 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.
