Description

Technical Field

[0001] The utility model relates to the technical field of paper mounting machines, in particular to a paper mounting machine with a glue self-cleaning mechanism. Background Art

[0002] A paper mounting machine is an important mechanical device, and its main function is to laminate two or more layers of paper together through an adhesive to form a composite paper with specific properties. Through this process, the paper can obtain greater thickness and strength, and at the same time, depending on the material of the selected surface paper, additional functions such as reflectivity and waterproofness can be imparted to the composite paper. Traditional paper mounting machines mainly include a face paper conveying device, a bottom paper conveying device, and a flattening device. During the paper mounting process, after the face paper and the bottom paper are accurately aligned and bonded together, they jointly pass through the flattening device to ensure the flatness and firmness of the bond.

[0003] However, during actual use, since the area of the bottom paper is usually larger than that of the face paper, during the pressing process, the part of the bottom paper that extends beyond the face paper will carry unused glue. These excess glues are likely to adhere to the pressing roller, and as the production process continues, the accumulation of glue may cause the face paper to adhere to the pressing roller, affecting the product quality and production efficiency.

[0004] In view of this, the inventor has specifically designed a paper mounting machine with a glue self-cleaning mechanism, and this case is thus produced. Content of the Utility Model

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more obvious, the following further details the present utility model in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0036] Embodiment 1

[0037] Please refer to Figures 1 to 5 , which is a paper mounting machine with a glue self-cleaning mechanism as the best embodiment of the present utility model, including:

[0038] A main body 10, having a conveyor belt device 11 at its upper end;

[0039] A facial paper conveying mechanism 20, arranged at the starting end of the conveyor belt device 11 and above it, and the facial paper is successively conveyed from the starting end of the facial paper conveying mechanism 20 onto the conveyor belt device 11;

[0040] A base paper conveying mechanism 30, arranged at the starting end of the conveyor belt device 11 and below it, and the base paper is successively conveyed from the starting end of the base paper conveying mechanism 30 onto the conveyor belt device 11;

[0041] A glue coating mechanism, arranged on the transmission path of the base paper conveying mechanism 30, for coating glue on the upper end surface of the base paper;

[0042] A pressing roller 40, arranged on the conveyor belt device 11 and after the intersection position of the facial paper conveying mechanism 20 and the base paper conveying mechanism 30. After the glue-coated base paper and the facial paper are accurately overlapped at the intersection position, they are then conveyed backward to the position of the pressing roller 40 for further pressing and fixing, enhancing the composite firmness of the base paper and the facial paper;

[0043] The cleaning device is arranged on one side of the laminating roller 40, and includes a scraper assembly 50, a limit baffle 60, a movable seat 70 and an adjusting assembly 80. The scraper assembly 50 is fixed on the movable seat 70 and is slidably arranged in the axial direction of the laminating roller 40 through the adjusting assembly 80. The limit baffle 60 is arranged on one side of the scraper assembly 50.

[0044] There are two scraper assemblies 50 and two limit baffles 60 , which are symmetrically distributed about the center of the laminating roller 40 . The two limit baffles 60 are located on the side where the two scraper assemblies 50 are close to each other.

[0045] Preferably, Figure 1 , 2 As shown, the main body 10 is provided with an installation space 12 below the laminating roller 40, and the upper end surface of the main body 10 is provided with a linear through groove 13 which passes through the installation space 12 and is parallel to the axial direction of the laminating roller 40. The adjustment component 80 includes a bidirectional screw 81, a guide rod 82 and a driving member 83 for driving the bidirectional screw 81 to rotate which are horizontally arranged in the installation space 12 and parallel to each other. The upper end of the movable seat 70 is provided with an internal screw hole (not shown in the figure) which can be threadedly connected to the threaded section at the corresponding position of the bidirectional screw 81, and the lower end of the movable seat 70 is horizontally penetrated with a guide hole (not shown in the figure) which is clearance-matched with the guide rod 82. The upper end of the movable seat 70 is provided with a support frame 71, and the upper end of the support frame 71 passes through the linear through groove 13 and is fixedly connected to the lower end of the scraper assembly 50.

[0046] Specifically, the bidirectional screw 81 has two threaded sections with opposite thread directions. The movable seat 70 is provided with a threaded sleeve 72 for threaded connection with the threaded sections at corresponding positions. The threaded sleeve 72 has the aforementioned internal threaded hole in the axial direction. Similarly, a linear bearing 73 is provided at the lower end of the movable seat 70. A smooth guide rod 82 is inserted into a guide hole formed on the inner side of the linear bearing 73. Thus, the movable seat 70 is limited by the guide rod 82 so that it can only move along the axial direction of the bidirectional screw 81. Subsequently, the position of the two movable seats 70 is changed by the driving member 83, thereby realizing the synchronous adjustment of the position of the scraper assembly 50.

[0047] In particular, in this embodiment, a coupling is provided in the middle section of the bidirectional screw 81, and the coupling is connected to a driving motor (not shown in the figure) for conveniently adjusting the position of the movable seat 70 through the driving motor.

[0048] Preferably, Figure 3As shown, the glue scraping assembly 50 includes a storage box 51, a glue scraping guide plate 52 that extends obliquely upward along one side edge of the storage box 51, and glue blocking plates 53 that are covered on both sides of the glue scraping guide plate 52 and are connected to the upper edge of the storage box 51. The upper edge of the glue scraping guide plate 52 away from the storage box 51 forms a sharp and linear scraper end 54. The glue scraping guide plate 52 and the glue blocking plates 53 on both sides enclose a glue guiding channel 55. An upper opening and glue storage groove 56 that communicates with the glue guiding channel 55 is formed inside the storage box 51. In this embodiment, the upper end surface of the support frame 71 is rotationally connected to the lower end of the storage box 51 through a damping hinge structure (not marked in the figure). Thus, by rotating the storage box 51 to make it rotate around the damping hinge structure, the scraper end 54 is brought into contact with the roller surface of the pressing roller 40. The rotation direction of the pressing roller 40 is such that the residual glue on the roller surface can be blocked and scraped off by the scraper end 54. Since the above process occurs during the paper mounting process, at this time, the residual glue still has a certain fluidity and can flow into the glue storage groove 56 along the glue guiding channel 55 for temporary storage and then be disposed of after it is full.

[0049] Preferably, as Figure 3 , 5 shown, a hot melting device 57 is provided in the glue storage groove 56. The hot melting device 57 includes a heat-conducting metal tube 571 disposed at the bottom inside the glue storage groove 56 and an electric heating device 572 connected to the heat-conducting metal tube 571. In this embodiment, the heat-conducting metal tube 571 is a copper tube, and the electric heating device 572 is a resistance wire. Thus, the residual glue stored in the glue storage groove 56 can be melted through the hot melting device 57, avoiding affecting the fluidity of the residual glue due to a long storage time and facilitating subsequent cleaning of the residual glue in the glue storage groove 56, such as pouring out or flowing out.

[0050] Preferably, as Figure 5 shown, the heat-conducting metal tube 571 is distributed in a snake shape inside the glue storage groove 56, thereby further enhancing the heating area of the residual glue and enhancing the heating and melting effect.

[0051] Preferably, in this embodiment, all the wall surfaces of the glue scraping assembly 50 are made of heat-conducting metal, specifically formed by welding steel sheets. Thus, through the heat conductivity of the steel sheets, the waste heat of the hot melting device 57 can be transferred, making it difficult for residual glue to remain and solidify in the glue guiding channel 55 and the glue storage groove 56, and improving the cleaning effect.

[0052] Preferably, as Figure 2 , 3 shown, a glue outlet 58 is provided at the bottom of the storage box 51. A plugging member 581 is detachably provided at the glue outlet 58. The glue outlet 58 is closed by the plugging member 581, and then opened when the residual glue needs to be cleaned, facilitating the control of the cleaning process.

[0053] Preferably, as Figure 2 , 4As shown, the limit baffle 60 includes a vertically distributed connecting section 61, a horizontal section 62 extending horizontally along the bottom of the connecting section 61, and a connecting shaft 63 fixed between the upper end of the connecting section 61 and the side wall of the scraper assembly 50. The bottom of the connecting section 61 extends to the upper end surface of the main body 10, and the side of the horizontal section 62 close to the laminating roller 40 is provided with an arc-shaped fitting groove 64 adapted to the roller surface of the laminating roller 40.

[0054] Thus, the limiting baffle 60 can achieve adaptive fitting with the roller surface of the laminating roller 40, a gap is generated on the wall surface, and good guidance of the bottom paper and the surface paper can be achieved, so that the bottom paper and the surface paper can be transmitted more smoothly between the limiting baffles 60 on both sides.

[0055] Embodiment 2

[0056] See also Figure 3 , is a paper laminating machine with a glue self-cleaning mechanism as the second embodiment of the utility model, which is different from the first embodiment in that the glue outlet 58 is conical and gradually decreases in the downward direction.

[0057] Preferably, a glue outlet 58 is provided at the bottom of the storage box 51, and the glue outlet 58 is detachably connected to a glue guide tube 582, and the glue guide tube 582 is a flexible tube, such as a plastic hose.

[0058] Therefore, through the cooperation of the tapered glue outlet 58 and the glue guide tube 582, a stable glue outlet path can be formed, so that the residual glue can be discharged stably.

[0059] Embodiment 3

[0060] See also Figure 6 , is a paper laminating machine with a glue self-cleaning mechanism as embodiment three of the utility model. The difference from embodiment one is that the driving member 83 is a hand wheel 84, which is arranged on the outer wall of the main body 10 and is transmission-connected to the bidirectional screw 81, so that the position of the scraper assembly 50 can be easily adjusted by the hand wheel 84.

[0061] The beneficial effects of the utility model are as follows:

[0062] The utility model adjusts the positions of the scraper assembly 50 on both sides of the laminating roller 40 through the movable seat 70 and the adjustment assembly 80 according to the actual width of the base paper and the face paper, so that the roller surface of the laminating roller 40 not covering the base paper and the face paper is covered by the scraper assembly 50, and the base paper and the face paper are laminated on the laminating roller 40 between the scraper assemblies 50 on both sides, and the limit baffle 60 synchronously limits the base paper and the face paper, so that the excess glue accumulated on the laminating roller 40 can be scraped off and the laminating of the base paper and the face paper can be better limited and guided at the same time, thereby improving the cleaning and laminating effects.

[0063] The present utility model has been described exemplarily in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above-mentioned manner. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
