Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mica plate production, and particularly relates to a mica plate fire-retardant glue automatic production equipment. BACKGROUND

[0002] In the manufacturing process of mica plate, a layer of fire-retardant glue is needed to be coated on the surface of the mica plate to improve its fire-retardant performance. However, in actual production, mica fragments will be attached to the surface of the mica plate in the forming process, which will have an adverse effect on the subsequent glue coating process. In the subsequent fire-retardant glue coating process, the mica fragments will be adhered to the surface of the glue coating roller, and then enter the glue containing groove to cause the outlet of the glue containing groove to be blocked, so that the glue liquid cannot be uniformly distributed on the glue coating roller, thereby causing uneven glue coating. In addition, the height of the glue coating roller of the existing glue coating device cannot be automatically changed according to the thickness of the mica plate during the working process, and manual adjustment needs to be performed after the mica plate specifications are changed, which reduces the flexibility of production and cannot realize dynamic flexible production of mica plates with different thicknesses.

DETAILED DESCRIPTION

[0032] The application is further described in combination with the following embodiments.

[0033] From Figures 1 to 6It can be known that the mica plate coating fire-retardant glue automatic production equipment comprises a forming device 11, a gluing device 12, a curing furnace 13, a bottom film pasting device 14 and a cutting device 15 arranged in sequence.

[0034] The gluing device 12 comprises a support 2; a transmission roller 21 is rotationally arranged at the bottom of the support 2; a sliding block 23 is movably arranged at the top of the transmission roller 21; a gluing roller 31 is rotationally arranged on the sliding block 23; the support 2 is provided with a connecting plate 3; the gluing roller 31 is rotationally arranged on the connecting plate 3; the connecting plate 3 is rotationally provided with an intermediate roller 32 and a driving roller 33; a gluing cloth 4 is movably arranged between the gluing roller 31, the intermediate roller 32 and the driving roller 33.

[0035] The support 2 is provided with a glue supply mechanism for supplying the gluing cloth 4 with fire-retardant glue and a filtering mechanism for filtering the mica fragments on the gluing cloth 4.

[0036] Specifically, the mica plate coating fire-retardant glue automatic production equipment forms the mica plate through the forming device 11, coats the mica plate with fire-retardant glue through the gluing device 12, solidifies the fire-retardant glue through the curing furnace 13 to form a fire-retardant layer, pastes a bottom film through the bottom film pasting device 14, and cuts the mica plate after the bottom film is pasted to obtain a finished product.

[0037] When the mica plate passes through the gluing device 12, the glue supply mechanism supplies the gluing cloth 4 with fire-retardant glue, the gluing cloth 4 transports the fire-retardant glue to the gluing roller 31, the gluing roller 31 coats the fire-retardant glue on the top of the mica plate when the mica plate moves to the lower side of the gluing roller 31 through the transmission roller 21, and the gluing cloth 4 drives the residual glue to pass through the filtering mechanism after the coating is completed, and the filtering mechanism filters the mica fragments.

[0038] In the embodiment, the gluing roller 31 is rotationally arranged on the sliding block 23, and the sliding block 23 is movably arranged at the top of the transmission roller 21, so that the gluing roller 31 can be lifted up when the mica plate passes through, and the height of the gluing roller 31 can be automatically adjusted according to the thickness of the mica plate; in addition, the filtering mechanism can filter the mica fragments to prevent the mica fragments from blocking the glue outlet groove 52.

[0039] The mica plate coating fire-retardant glue automatic production equipment comprises a support 2; a motor 24 is fixedly arranged on the support 2; and the output end of the motor 24 is connected with the driving roller 33.

[0040] The support 2 is provided with an arc-shaped groove 22; and the sliding block 23 is slidingly arranged in the arc-shaped groove 22.

[0041] Specifically, the embodiment drives the driving roller 33 to rotate by the motor 24, and when the driving roller 33 rotates, the rubber coating cloth 4 can be driven to move between the rubber coating roller 31, the intermediate roller 32 and the driving roller 33.

[0042] In addition, since the driving roller 33 is fixed on the motor 24, when the sliding block 23 moves up and down along the arc-shaped groove 22, the rubber coating roller 31 and the connecting plate 3 can be driven to rotate around the driving roller 33 as the axis, so that the stability of the overall structure can be ensured.

[0043] The mica plate fire-retardant glue automatic production equipment has the advantages that the height of the intermediate roller 32 is higher than the height of the driving roller 33, and the height of the driving roller 33 is higher than the height of the rubber coating roller 31, so that the stability of the overall structure can be ensured.

[0044] The mica plate fire-retardant glue automatic production equipment has the advantages that the rubber coating cloth 4 is formed with a glue containing section 41 between the intermediate roller 32 and the driving roller 33.

[0045] The support 2 is provided with a sealing plate 42 on both sides of the glue containing section 41, and the two sides of the glue containing section 41 abut against the sealing plate 42.

[0046] The glue supply mechanism comprises an adjusting plate 5 and a glue supply pipe 25 provided on the support 2, the two sides of the adjusting plate 5 abut against the sealing plate 42, a glue containing cavity 43 for storing fire-retardant glue is formed between the adjusting plate 5, the sealing plate 42 and the glue containing section 41, the glue supply pipe 25 is arranged at the top of the glue containing cavity 43, the bottom of the adjusting plate 5 is provided with an inclined section 51, and a glue outlet groove 52 is formed between the bottom of the inclined section 51 and the glue containing section 41.

[0047] Specifically, in use, the glue containing cavity 43 is formed between the adjusting plate 5, the sealing plate 42 and the glue containing section 41, then the glue supply pipe 25 supplies fire-retardant glue to the glue containing cavity 43, and the fire-retardant glue in the glue containing cavity 43 flows to the surface of the rubber coating cloth 4 between the driving roller 33 and the rubber coating roller through the glue outlet groove 52, so that the rubber coating roller can coat the fire-retardant glue on the surface of the rubber coating cloth 4 on the mica plate.

[0048] The mica plate fire-retardant glue automatic production equipment has the advantages that the glue supply mechanism further comprises a fixing plate 6 provided on the support 2, the fixing plate 6 is threadedly connected with a screw rod 61, the screw rod 61 abuts against the adjusting plate 5 after penetrating through the fixing plate 6, the adjusting plate 5 is provided with a limiting column 53, and a reset spring 54 is arranged between the limiting column 53 and the fixing plate 6 after penetrating through the fixing plate 6.

[0049] Specifically, by setting the screw rod 61, the adjusting plate 5 can be moved towards the direction of the rubber coating cloth 4 by rotating the screw rod 61; or the screw rod 61 can be moved away from the adjusting plate 5 by rotating the screw rod 61, and under the resetting action of the resetting spring 54, the adjusting plate 5 is moved away from the rubber coating cloth 4; therefore, the width of the glue outlet groove 52 between the bottom of the inclined section 51 and the glue containing section 41 can be adjusted by rotating the screw rod 61, so that the glue amount can be adjusted.

[0050] The mica plate fire-retardant glue coating automatic production equipment has the first cavity in the glue coating roller 31; the support 2 is provided with the cold water injection mechanism 71 which is communicated with the first cavity; the second cavity is arranged in the intermediate roller 32; and the support 2 is provided with the hot water injection mechanism 72 which is communicated with the second cavity.

[0051] Specifically, the temperature of the glue coating roller 31 is low due to the cold water in the first cavity, so that the viscosity of the fire-retardant glue at the glue coating roller 31 is larger, and more fire-retardant glue is coated on the surface of the mica plate; in addition, the residual glue on the rubber coating cloth 4 is heated when the rubber coating cloth 4 carrying the residual glue passes through the intermediate roller 32, so that the viscosity is smaller, and the flowability of the fire-retardant glue is better, facilitating the filtration of the mica fragments.

[0052] The mica plate fire-retardant glue coating automatic production equipment has the first cavity in the glue coating roller 31; the support 2 is provided with the cold water injection mechanism 71 which is communicated with the first cavity; the second cavity is arranged in the intermediate roller 32; and the support 2 is provided with the hot water injection mechanism 72 which is communicated with the second cavity.

[0053] Specifically, when the rubber-coated cloth 4 carrying the residual glue passes through the intermediate roller 32, the residual glue on the rubber-coated cloth 4 is heated, so that the viscosity becomes smaller, and the flowability of the fire-retardant glue is better, on the one hand, the flow resistance of the fire-retardant glue is smaller, and the filtering efficiency is improved; on the other hand, the large mica fragments with heavy quality in the residual glue are at the bottom layer of the residual glue under the action of gravity, and the small mica fragments are at the top layer of the residual glue under the action of gravity; therefore, when the residual glue passes through the large fragment retention area 82, the blocking groove 91 is more likely to retain the large mica fragments in the large fragment retention area 82 through the blocking groove 91, so as to avoid the large mica fragments entering the small fragment retention area 83 to block the filtering groove 92 and cause the filtering efficiency to be reduced; after the small mica fragments are filtered by the filtering groove 92 of the small fragment retention area 83, the residual glue flows back to the glue containing cavity 43.

[0054] The large fragment retention area 82 and the small fragment retention area 83 are both inclinedly arranged on the support 2; and the inclination angle of the large fragment retention area 82 is smaller than that of the small fragment retention area 83. Through the above arrangement, the flow of the residual glue can be accelerated.

[0055] The small fragment retention area 83 is provided with a hinge part 84 at the end away from the large fragment retention area 82; the hinge part 84 is rotationally connected with the support 2; the top of the hinge part 84 is provided with a limiting plate 85; the limiting plate 85 is provided with an elastic piece 86; and the elastic piece 86 abuts against the glue supply pipe 25. Specifically, since the connecting plate 3 can move, the intermediate roller 32 can move; through the arrangement of the hinge part 84, the limiting plate 85 and the elastic piece 86, the abutting part 81 can always abut against the end of the glue containing section 41 close to the intermediate roller 32 during the movement of the intermediate roller 32.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit the protection scope of the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present application.
